Apparatus and method for using multi-element load distribution to perform fitness exercises that simulate riding a bicycle

APPARATUS AND METHOD FOR PERFORMING A SIMULATED BICYCLING EXERCISE USING MULTIPLE ELEMENT LOAD DISPERSION

The present invention is generally related to the field of fitness equipment, and more specifically to a fitness device for aerobic, resistance, balance and skill training, which allows the user to perform a fitness exercise that simulates riding a bicycle .

The cardiopulmonary, cardiovascular, and strength training fitness equipment that can be seen in today's fitness centers and at home is pursuing the improvement and maintenance of personal aerobic and strength fitness. Many types of fitness equipment, including treadmills, boat trainers, stationary bicycles, steppers, ski machines (cross-country and alpine skiing), and dry-land swimming training machines are necessary to maintain and enhance their The overall health status and health-regulated individuals can be obtained.

Stationary bicycles provide users with a mechanism for exercising certain muscles, which generally involve the legs, and if any, involve the central core to a small extent, that is, help the rider's Balanced abdominal muscles and lower trunk muscles; arm and upper body muscles, that is, biceps, triceps, obliques, and back muscles. The current state of stationary bicycle design has generally been limited to the following design: attaching a handle, pedal and seat to, for example, a single rigid platform bolted in place and resting on the floor, the platform is Constructed to replicate only the spin dynamics associated with pedaling bicycles. In this configuration, the current design can only It can simulate some of the very limited total dynamic forces that can be achieved when actually riding, for example, a traditional bicycle, and makes the user in a fixed and unchanging posture, which is different from the traditional bicycle. Operating the current stationary bicycles in a fixed posture or position because the contact pressure of the seat is still quite fixed when riding a stationary bicycle, which may cause certain nerves in the rider's body and the body close to the bicycle seat Part, like the prostate, becomes numb.

The current stationary bicycle design cannot replicate or simulate the actual dynamic force displayed when riding a traditional bicycle, and it also limits the number and types of muscle groups involved in the residence. These designs cannot engage in many muscles that need to be stimulated and balance traditional bicycles, and these stationary bicycles cannot satisfy certain core muscles in the rider's physique. These stationary bicycles can be considered unpopular and generally not suitable for training by enthusiasts and dedicated competitors. A design that is restricted in this way cannot simulate the overall experience of riding a bicycle, and does not involve the muscle groups that can be obtained when riding a bicycle.

Other designs try to improve the simulation situation by involving the use of existing traditional bicycles positioned on fixed rollers or on a frame in which the rear tire does not make contact with the ground. Such a stand can use a resistance mechanism, such as a stand for magnetic training equipment.

The fixed roller design generally involves a traditional bicycle and a fixed cylindrical rolling mechanism, in which the rider first places the bicycle on a series of rollers. Once the bicycle is properly positioned, the cyclist can board and begin to pedal a traditional bicycle with his feet Heng this traditional bicycle. One of the main reasons for the unpopularity of fixed roller designs is that they are very difficult to learn and precise to master, and their operation can be very dangerous. Although this type of design can provide additional comfort because the seat can move relative to the contact area of the rear tire and the roller, and can allow the torque from the pedal to affect the movement of the bicycle on the roller, this The configuration method is still undesirable because this design does not release the pressure on the seat contact area, that is, the "bicycle seat" that has numbness of nerves or body parts adjacent to or close to the seat. Chair complications". The roller design does not allow the user to properly lean and control the bicycle while exercising.

The stand designs including those using magnetic training equipment are similar in operation to current stationary bicycle designs and subject to the same limitations as those found in roller and stationary designs.

Part of the issues related to the design of a stationary bicycle with a rolling mechanism is the fact that the design of mounting on a stationary roller and starting pedaling on this design is quite different from starting a bicycle. The roller design is also easy to cause the overall bicycle to operate aimlessly, causing the user to lose balance or slip off the roller. Since the rollers are generally positioned on a hard surface, such as the concrete floor that can generally be seen in gyms and health centers, if the user loses his balance at any point during fitness, the user generally You will fall and hit the ground, and you will be vulnerable to possible injuries.

In order for the cyclist to properly ride a traditional bicycle, the user must provide propulsion by rotating the pedal, control the direction of the bicycle by the steering handle to drive, and maintain balance, that is, Tilt, turn, stop, accelerate and decelerate, etc. Riding a bicycle properly requires a person or user who is riding a bicycle to apply many complex and dynamic steering and tilting forces in multiple directions at the same time on the handlebars, pedals, seats, or any combination, and change the strength To balance, control, drive and propel the bike. The bicycle rider can provide additional control forces to further control and guide the frame. ), that is, the amount of lean forward, deflection, and so on.

Today's fixed designs cannot fully reflect the steering and forward tilt forces that users apply to the pedals, handles, and seats. The roller design is still difficult and dangerous to operate, and it is still not suitable for use in group or class environment settings.

The current stationary bicycle design system tends to be quite restricted by the significant dynamic interaction between the user and the device occurring at the pedal, which limits the fitness simulation of the pedaling part of the riding experience. These designs limit the muscle groups involved and the quality of the spin effect that may be produced. Users of these devices may be interested in devices that can simulate the complete experience of riding a bicycle, and hope to obtain benefits involving a wider range of muscle groups required for riding a traditional bicycle.

Due to the wear of certain parts, certain problems may occur, and other problems related to overall riding comfort may occur. It is necessary to provide a bicycle fitness design that can last for a long time, can withstand a large amount of wear, and provide a riding characteristic that almost simulates a user riding a real bicycle.

Therefore, it is beneficial to provide a more accurate simulation of traditional bicycles It is a bicycle fitness device which is operated and overcomes the limitation of the current fixed bicycle design.

According to an aspect of the design of the present invention, a device is provided that allows a user to perform a fitness exercise that simulates riding a bicycle. The design includes a frame with a first lower front frame position point and a second upper rear frame position point. The first lower front frame position point includes a multi-element distributed load configuration, and the second The upper rear bracket position point includes a pin that defines an axis that substantially represents a line that combines the second upper rear bracket position point and the first lower front bracket position point. The design also includes a seat connected to the frame, the frame being constructed to support the user and a wheel, and multiple pedals that interact with the wheel. The frame is constructed to be able to pivot around the axis corresponding to the user's leaning.

The handle can be set to enable the application of force, and to enhance the leaning or pivoting effect of the simulated experience of bicycle riding.

From the following detailed description of the present invention and the accompanying drawings, these and other advantages of the present invention will become apparent to those who are familiar with the technology.

The design of the present invention is a bicycle fitness device. Generally speaking, the device includes a bicycle frame and elements attached to a fixed frame, namely, handles, receivers worn on the head, pedals, seats, and chains. The drive and flywheel, the fixed frame is generally positioned on a smooth surface such as a hardwood or concrete floor, and the device can pivot or rotate with articulations relative to the two bracket positions. These frame positions are constructed between the fixed frame and the bicycle frame, and can allow the bicycle rider to move the entire frame and components to the left and right, and when the bicycle rider steps on or When "coasts" are not stepped on, the bicycle is tilted forward within the fixed frame in response to the force applied to the handlebars, pedals, and seat.

Basically, the front and rear frame seat positions are platforms that suspend the bicycle frame in the space, allowing the bicycle frame to pivot or rotate in the left and right directions with joints, and connect the bicycle as a single joint. Leaning forward, more precisely, simulates the forces encountered in actual riding a bicycle. For example, in this configuration, the suspended bicycle frame can respond to the moment generated by the pedaling action of the rider, causing the frame to move or tilt forward within the fixed frame. In a similar way, the suspended bicycle frame can be applied to the handlebars, pedals, and seat in response to the guidance of the rider, and these forces also cause the bicycle frame to fall within the fixed frame. Lean forward or move around in space. For example, a person riding a bicycle can move his hips from side to side, where the force system applied to the seat will cause the bicycle frame to move from left to right or from right to left , And simulate turning the bicycle through the seat in a way that can be compared with the way a traditional bicycle is moving on a road.

In addition, people riding bicycles can Operating the present invention is designed to use his hips to reposition his body relative to the bicycle frame for balancing and maneuvering the bicycle. Furthermore, a person riding a bicycle can get up from the seat, take himself out of the seat, transfer his body mass to the handles and pedals, while still pedaling, and can throw his weight from one side to the other to simulate climbing. Slope, a technique used by riders in often competing bicycle races. People riding a bicycle can generate force by operating in this position away from the seat or by turning on the pedal. Combined with the force generated by the turning action of the flywheel element, a turning effect can be produced, allowing the back of the device to go back and forth. "Wag" to simulate the actual behavior and operation of a traditional bicycle.

The bicycle fitness device may include a handle that steers with the bicycle, or the handle may be fixed or loose and can move freely. The drive line designed by the present invention can be fixed so that the action of stepping forward will cause the flywheel to move in the forward direction that would be considered to be on a conventional bicycle, while stepping backward will cause the flywheel to move in the opposite direction. , Or it can be unrestricted, in which stepping forward will cause the flywheel to move, while stepping backward, that is, the wheel rotates freely, it will not provide resistance or apply force to the flywheel. A blocking mechanism can be provided to fix the relationship between the fixed frame and the bicycle frame that allows the device to operate and run according to the current fixed bicycle design.

Other materials may be used to manufacture the components and elements used to form the assembly to construct the bicycle fitness device designed in accordance with the present invention.

From Figure 1, the fixed frame 101 or base or base component designed by the present invention can be constructed from multiple sections made of steel, where section 105 generally uses at least one steel flange or bracket element It is attached to a connection location point. For example, FIG. 1 illustrates a top flange and a bottom flange at the element symbol 125, and at least one bolt, nut, and washer set at the element symbol 126 or other assembly means such as welding, which are It is sufficient to secure one or more sections 105 when the top and bottom flanges at the element symbol 125 are tightly fitted. Another type of attachment element may include a 90-degree elbow bracket at the element symbol 120, a flat bracket at the element symbol 121, and suitable to fit one or more sections 105 in a tight fit or Other types/shapes of brackets for the purpose of fastening these sections when combined with each other. Although the construction technique described herein uses multiple sections, brackets, and flanges, forming the fixed frame 101 may have to provide a single component with the described functions. Generally speaking, the base or base assembly must support the frame, and allow the user or rider to step on, lean over, and perform the functions discussed in this article, and can Different from the depicted components.

Figure 1 illustrates the construction of the frame 102 or frame assembly of the present invention, which involves a plurality of frame pipes formed of steel, such as top pipes, lower pipes, head pipes, seat pipes, chain stays and seats Strut. Generally speaking, the pipe element 130 is attached by glue or is formed by welding two or more pipe elements together to form the frame 102, or other pipe elements used as a frame. 130 is designed according to the present invention to be a mechanism sufficient to fasten the sub-element when assembled together.

The top tube connects the head tube to the seat tube at the top, the lower tube connects the head tube to the bottom bracket shell, the head tube accommodates the receiver on the head and connects the top tube to the lower tube , The seat tube accommodates the seat column and supports the seat, and connects the top tube to the bottom bracket shell, the chain brace extends parallel to the chain and connects the bottom bracket shell to the rear extension, and the seat brace connects the seat The top of the pipe fitting is connected to the rear splicing part. Those familiar with the technology should have a good understanding of the terminology used to describe the structure of the present invention.

The design of the present invention can attach the drive line assembly 109 to the frame 102. The drive line assembly 109 can support the pedals and provide a place for positioning the feet, and can help the user maintain the balance of the frame 102 suspended in the fixed frame 101 while performing a simulated bicycle fitness exercise. The drive line assembly 109 may include a pedal and flywheel subassembly configuration. The pedal subassembly may include a pedal 106 that provides a place for the user to position his or her feet, a crank arm 107 for attaching the pedal 106 to a chain ring, and a bottom bracket support element (not shown in the figure) ), And it is possible to connect a first crank arm 107A to a second crank arm 107B element. The flywheel subassembly may include a fixed gear element (not shown in the figure) that is firmly installed and attached to the flywheel 108. The fixed type, that is, a single gear, can optionally be replaced by a set of gears (for example, a cassette), and an appropriate shift mechanism element that allows the user to change the magnitude of the pedaling resistance experienced while pedaling To replace.

A chain or belt element (not shown in the figure) can transmit the force applied by the user who spins the pedal 106 from the pedal sub-assembly to the flywheel sub-assembly. The chain or belt element is generally constructed to be used by positioning the chain on the front chain ring and on a fixed single gear, or selectively on a set of gears, and attaching a key chain connection. (Not shown in the figure) to form a single continuous chain loop, the front chain loop element is matched or connected to the rear fixed gear element, and such a design is generally known in the art. A cover on the top of the drive line assembly 109 for the purpose of protecting the user during operation and providing access to the previously described drive line elements can cover the chain, chain ring, and fixed gear elements. The design of the present invention may involve a free-wheel assembly or a direct drive assembly together with the chain, chain ring, and related chain drive elements in the drive line assembly 109 to operate or spin the flywheel 108.

The design of the present invention can be attached to the control assembly at the front of the frame 102 as illustrated in FIG. 1. The control component can support the handle element, allowing the user to have a place to place his hand, and is used to help the user perform a simulated bicycle fitness exercise while keeping the frame 102 suspended within the fixed frame 101 balance. The control component handle 110 components generally come It is equipped with a grip or a strap suitable for being held by the user, which is used to "steer" the design of the present invention and can be used in conjunction with the drive line assembly 109 to help the user in pedaling Come and keep your balance while performing simulated cycling exercises.

The handle 110 is generally fixed at one end of the handle 111 by tightening a clamping mechanism at the symbol 112. For the purpose of simplification, the illustrated handle 111 passes through the top of the frame element of the head tube and protrudes at the bottom of the frame element. The other end of the handle 111 can be attached to an adjustable swing arm 113 device, wherein the swing arm 113 can be set to a fixed position by tightening the adjustable collar at the symbol 114.

According to an aspect of the design of the present invention, the bicycle fitness device 100 can use a traditional head-mounted receiver configuration for attaching the handle 111 to a control connection positioned through a head tube via an adjustable clip 127Pipe fittings128.In this configuration, the other end of the manipulation connector tube 128 can be attached to an adjustable swing arm 113 device, where the swing arm 113 can be tightened by tightening the adjustable collar at the symbol 114 Set to a fixed position.

Continuing, the handle 111 may be configured to connect the power manipulation force input at the handle 110 and applied by the user, and transfer the force received at the handle 110 to the first stand 103. Although most of the force can be transferred from the handle 111 or the manipulation connector tube 128 to the first mount, a small force can also be transferred to the second mount 104.

As shown in Figure 1, the design of the present invention can attach the sitting component in place Above the drive line assembly 109 at the pipe frame element under the frame 102. The seat assembly can support the seat 115 or the car seat, and can provide users with a place to place their upper legs and contact their upper legs with the core, so as to help maintain maintenance while performing simulated cycling exercises. The balance of the frame 102 suspended in the fixed frame 101 is designed according to the present invention. According to the design concept of the present invention, the seat assembly may include a seat 115 fixed to the seat pillar 116, which is sufficient to provide a sitting posture that allows the user to properly position his body on the frame 102 and provide additional manipulation force input To lean further and turn to the frame 102.

The seat assembly can be used in conjunction with the drive line assembly 109 and the control assembly to help the user maintain balance while rotating the pedals to perform a simulated bicycle fitness exercise. The design of the present invention can fix the seat 115 to one end of the seat post 116 by tightening the clamping mechanism at the element symbol 117. The other end of the seat post 116 is generally fixed to the lower tube frame element portion of the frame 102 by tightening the adjustable collar at the element symbol 118. The bicycle fitness exercise device may be configured with a seat post 116 to connect the power manipulation input applied by the user at the seat 115 and transfer these forces to the second frame 104. Again, although most of the force can be transferred from the seat post to the second frame, small forces can also be transferred to the first frame 103.

The connection configuration and the transfer of force from the handle 110, the pedal 106 and the seat 115 will be described further below.

Figure 2 illustrates the formation along the main axis 203 designed in accordance with the present invention A side view of the angular relationship between the first frame 103 and the second frame 104. According to the design concept of the present invention, the first frame 103 may include an elastic spring 201 device for attaching and suspending the frame 102 within the fixed frame 101 at a forward position. According to another aspect of the design of the present invention, the second frame 104 may include a pivoting ball joint 202 device for attaching and suspending the frame 102 within the fixed frame 101 at a rear position.

The elastomer spring shown is related to the position of the front and lower frame, but such a device or similar device can be connected to the position of the upper frame (the second frame 104) or the position of the lower frame (the first frame 103). ) Or both. In addition, although the orientation of the bracket position points shown is at different predetermined distances above a surface such as a floor or an upright or flat ground, it should be understood that when the bracket position points and the main axis formed thereby are The function described in this article can be achieved when the value of the level change is included.

These two frame position points, together with the user input provided at the handle 110, the pedal 106 and the seat 115, can allow the fixed frame 101 to be tilted forward or articulated relative to the main shaft 203 of the frame 102. Pivot. The ability of the bicycle frame to tilt, lean and/or roll back and forth and horizontally in a way that deviates from the main axis is not available on the conventionally designed stationary exercise bikes. The ability of the frame 102 to pivot and rotate in the space defined by the position of the frame fixed to the fixed frame can significantly more accurately simulate the riding of a bicycle. The precise simulation achieved by operating the design of the present invention may involve exercise and training that are not involved when operating the current stationary exercise bike design Muscle groups.

First, the suspension technology of erecting the frame 102 can use the elastomer spring 201. However, such a stand may include a hydraulic strut or other components suitable for providing suspension and spring elements designed in accordance with the present invention. The second frame 104 may involve a pivoting ball joint 202 that is assembled to form a rear suspension point for the frame 102. Generally speaking, the ball joint assembly can be constructed to connect the frame 102 to the fixed frame 101. The ball joint design may include a support stud and a bracket surrounded by a shell (not shown in the figure) generally constructed of steel. In one example, the housing surrounding the socket can provide an installation configuration that allows the housing to be attached and fixed to the frame 102. The ball joint bearing generally sits on the inside of the shell and can support a threaded stud structure. The threaded stud can be fastened or fastened by a fixed frame 101 with a washer and nut configuration. The ball joint 202 can be constructed to suspend the frame 102 and allow pivotal movement within a fairly well defined semicircle established by the fixed frame 101 at the position of the second mount. The design of the present invention is not limited to the use of a ball joint 202 at the second bracket position, and any device or element that can perform a range of motion or pivot around the bracket position can be used. Those who are familiar with this technique should have a good understanding of the use and assembly of a ball joint device constructed to suspend one part from another. The first and second seat positions may involve an elastomer sleeve through which a bolt passes, or may involve a ball-and-socket device. In another example, the first and second pedestal position points may involve the end of the spherical rod member, or together with an extension A sleeve that extends through the tube of each sleeve.

As used herein, the term "elastomer" is generally used to describe a material formed using vulcanized rubber, but again in the orientation or configuration shown or other configurations (for example, near the upper and/or lower frame positions) In point), other resistant materials can be used as resistance elements, and the term elastomer is not intended to be used as a restriction. The actual elastomer material can tolerate considerable movement when subjected to external forces. Generally speaking, elastomeric materials are characterized by their ability to deform when subjected to an external force and return to their original shape when there is no external force. The ability to buckle or deform and return to their original shape can provide a spring-like resistance effect. The spring effect exhibited at the first stand and the pivoting action exhibited at the second stand, when aligned along the main axis 203 and combined with the previously described assembly, allows the user to rock back and forth And swing the frame 102 horizontally, and simulate the steering at an angle, that is, generated from the user's forward lean, steering, and a combination of these, and at the same time generate a kind of simulating bicycle fitness exercise by rotating the pedals A steering effect similar to "feedback from the road". The spring-like resistance effect can involve any type of spring device that is suitable for performing the function of the first or second stand by allowing the frame 102 to return to a neutral position.

As used herein, the term "roll" or tilt angle is generally used to describe rotation or pivoting around a main axis called the longitudinal main axis, which is shown as being drawn in the diagram. In the direction the user is facing, the main axis of the seat is reached from the handle through the design. Use the word water Panning means to define the rotation relative to the vertical main axis drawn from the top pipe frame element to the bottom pipe frame element and perpendicular to the main axis of the front and back shaking. The terms pivot, shake back and forth, shake horizontally, lean forward, and lean together in this disclosure are used to describe the horizontal and vertical movement of the frame 102 within the fixed frame 101 and relative to the described main axis or element Or the offset of the angle. Figure 2 illustrates the assembled bicycle fitness exercise device 100, which includes a fixed frame 101, a frame 102, a drive line, a control, a seat, and a bracket position point assembly; it is constructed to allow the user to use a circular shape The pedal 106 is operated by the rotating or rotating action of the pedal, and is configured to help the user maintain a balance while performing a simulated bicycle fitness exercise.

The handle 110 can receive a force derived from the user's hand, such as turning left, and connect or transfer the force to the frame 102 through the handle 111. In addition, the force may be derived from the user pushing on the side of the seat 115, such as pressing down the upper left leg or the area of the thigh, and the force may be transferred to the frame 102 through the seat pillar 116. Furthermore, the pedal 106 can receive the force derived from the user's feet, and can connect the force to the frame 102 through the drive line assembly 109. The force received by the frame 102 can be lost due to the following reasons: the suspended bicycle frame surrounds the elastic body spring 201 and the bracket position device of the pivoting ball joint 202 and is located within the space defined by the fixed frame 101 Forward tilting, tilting, rocking back and forth, horizontal rocking, or articulated pivoting.

The force elimination mechanism between the frame 102 and the fixed frame 101 may involve the construction of a pivoting ball joint 202 installation device An elastic body spring 201 holder position point device is provided, wherein the devices are positioned and aligned along the main shaft 203, as illustrated in FIG. 2. The force transfer mechanism can enable the design of the present invention to transfer the force while the user applies the force to the handle 110, the pedal 106 and the seat 115, and can allow the bicycle fitness exercise device to absorb, distribute and disperse the source It comes from the force generated by the user while pedaling, turning the handle, and maintaining balance. In other words, the design of the present invention can transform the force applied to the handles, pedals, and seats into the force absorbed and dissipated by the front and back rocking and horizontal rocking forms of the frame 102, thereby generating a frame 102 relative to the fixed frame 101 moves from side to side. The bicycle fitness exercise device 100 is used to transfer the force from the handle 111 and the seat post 116 (not shown in the figure) to the element of the elastomer spring 201 is shown in FIG. 3 and discussed below.

Figure 2 shows the design of the present invention, which is constructed to allow the user's hand and seat position to be adjusted relative to his feet or pedals, and to adjust the first frame 103 and the second frame 104 relative to each other. Angular relationship formed by the alignment of the main shaft 203. The design of the present invention can allow the handle 110 to move forwards and backwards relative to the head tube 208 at the position point 204, and the handle 110 can be exposed or protruded in the adjustable clamp by increasing or shortening the handle 111 The amount of the head tube 208 at 127 moves up and down at the position point 205. In a similar manner, the design of the present invention can allow the seat 115 to move forwards and backwards relative to the seat tube 209 at the position point 206, and the seat 115 can be exposed or protruded from the seat tube by lengthening or shortening the seat post 116 209 to move up or down. The ability to adjust or reposition the handles and seat allows users to modify the geometry of the frame and properly position their body mass relative to the frame to accommodate the arms and legs of riders of different heights. Properly positioning the mass of the user's body relative to the two mounts aligned along the main axis 203 can enable the simulation designed in the present invention to be converted into the user's size. Such conversion may include changing the elements displayed and/or the elastomer used.

The angular relationship formed by the movement of the first frame 103 and the second frame 104 relative to the main shaft 203 along the main shaft 203 can be described in conjunction with the combination of horizontal and vertical components used in this design. The horizontal offset component may be generated by the frame 102 moving in the horizontal direction when measured from a stop or static position within the space established by the fixed frame 101. The vertical offset component may be generated by the frame 102 moving in the vertical direction when measured from a stop or static position within the space established by the fixed frame 101. The angular relationship caused by the user's input such as turning the handle and/or pressing the thigh into the seat, etc., that is, forward, tilt, forward and backward rocking, horizontal rocking, or any combination of these The amount can be described by dynamically changing the horizontal and vertical offset caused by the frame 102.

According to the design example of the present invention, the combination of these two angular offsets forms an angular relationship that specifies the movement in the two spatial dimensions. In general, when used in this document, the term horizontal offset, that is, rocking back and forth, or other similar terms, refers to the top pipe frame element illustrated in FIG. 2, where the frame 102 is such as the bottom The lower part of the bracket is the one of the orientations of "entering toward the page" and "leaving the page". direction. The term vertical offset, that is, horizontal shaking, or other similar terminology, when compared with the frame 102 as illustrated in FIG. The position is the direction in one orientation that moves "leftward" or "rightward". The combined effect of the horizontal and vertical offset produced by the design of the present invention is illustrated in FIG. 6.

Furthermore, the angular relationship formed between the two bracket positions is combined with the structure of the installation device, such as the elastomer spring 201 device and the pivoting ball joint 202 assembly, which can produce a control effect and allow it to be changed. The tilt-to-turn ratio, that is, the pivoting of the joints relative to the two bracket positions, is used to closely simulate the experience achieved when operating a traditional bicycle. The tilt-to-steer ratio can be produced by the combination of the user moving the handlebar and leaning on the seat and lifting or pushing against the pedal. In this configuration, the design of the present invention can allow the user to steer by simulating tilt at an angle obtained when operating a conventional bicycle in a similar manner. The control effect or force generated by the design of the present invention can provide a realistic "feedback from the road" as analog information, which is transmitted like the reaction force received by the user at the handle, seat, and pedal. The user can process the simulation information generated by the design of the present invention to determine the magnitude and duration of the required force. The simulation information is provided as input to the handle, pedal, and seat, as if it were sufficient to simulate The continuous adjustment of the way of controlling and maintaining balance while exercising on bicycles is provided.

This orientation is generally used during operation, but as It can be seen that the bicycle exercise device 100 may include a blocking mechanism (not shown), which prevents the frame 102 from moving relative to the position of the suspension frame seat during operation to produce a simulation effect of a traditional stationary exercise bicycle.

In addition, the design of the present invention can optionally involve transport wheels 210 to help the mobile device, brake cables 211 and hand brake 212 that provide control of the rotation speed of the flywheel 108, and a tension adjustment mechanism 213. The adjustment mechanism 213 is used to move one or more brake pads or to move one or more brake pads by resisting a flywheel or similar friction device suitable for providing resistance to stepping while performing the pedaling action designed according to the present invention. The brake pad moves away from the flywheel or friction device to control the amount of resistance applied to the flywheel 108.

Various views of the first stand 103 are illustrated in FIG. 3, FIG. 4, and FIG. 5. Figure 3 illustrates the first stand 103 in a parked or static position. FIG. 4 illustrates the resultant deformation of the user turning the handle and pressing on the elastic spring device at the first bracket 103. A view of an exploded part of the first frame 103 and a schematic assembly are illustrated in FIG. 5.

Figure 3 is a close-up view illustrating the suspension mechanism of the first frame, which involves an elastomer spring 201 device attached to a manipulation input assembly that can be used with the design of the present invention. The first frame 103 generally uses an elastomer material 301 and is positioned between a top plate 302 and a bottom plate 303. Generally speaking, the elastomer material can be used to simply fix the elastomer material and the top and bottom plates in place by a through bolt or be suitable for connecting the elastomer material and the top and bottom plates. The bottom panel is held in place by other mechanisms, while being aligned and positioned between the top and bottom panels.

The top plate 302 illustrated in FIG. 3 can generally attach the first frame 103 to a fixed frame section 105 by welding the section 105 to the bottom side of the top plate 302. In addition, the top plate 302 may include a fixed arm 304, wherein one end of the fixed arm can be welded or bonded, otherwise it is attached to the top side of the top plate 302. At least one mounting hole 305 may be provided at the other end of the fixed arm 304. The mounting hole 305 can allow a connecting rod 306 to be assembled between the fixed arm 304 and the swing arm 113 device. The design of the present invention can allow the use of a threaded sleeve configuration as shown in the figure to change the length of the connecting rod 306, and can use a bolt, nut washer configuration or other designs suitable for attaching the connecting rod according to the present invention The fastening device of the piece is fastened to the swing arm 113 and the fixed arm 304. The design of the present invention can allow the effective length of the swing arm 113 to be changed by positioning and fastening the connecting rod 306 on one of the plurality of holes located at the component symbol 310, as shown in FIG. 3, the holes The holes are located at different distances from the center of the handle 111. Changing the effective length of the swing arm 113 can modify the amount of deformation achieved by the elastic body spring 201 device, thereby increasing or decreasing the force generated by the rotating handle 110. In addition, changing the effective length can change the overall range of movement of the handle relative to the frame 102.

The bottom plate 303 illustrated in FIG. 3 can generally be welded to the bottom side of the bottom plate 303 by fusing a mounting bracket 307 and using a fastener such as a bolt, nut, and washer configuration. First frame 103 Attached to a pipe element used to form the frame 102, the frame element connected to a bottom pipe 320 is shown to match and attach the frame element of the bracket 307 to the bottom pipe 320 of the frame 102. Although illustrated using a bolt, nut, and washer configuration, the mounting bracket 307 may be connected to the bottom tube by welding or other mechanisms sufficient to fasten the mounting bracket to the frame member.

The elastomer material 301, the top plate 302, and the bottom plate 303 are each constructed with a mounting hole for receiving a fastener configuration such as a combination of bolts, nuts, and washers, for attaching the first The stand 103 is attached to the fixed frame 101 and the frame 102. It can be noticed that the mounting holes cannot be seen in this view.

FIG. 4 is a close-up view of the design of the present invention in a steering position, which illustrates that the suspension position point mechanism in front of the first frame involves an elastomer spring 201 device attached to a steering input assembly. As described above, the design of the present invention can transfer the rotational movement of the handle 110 in the left or right steering position by moving the swing arm 113 in proportion to the movement of the handle 110. Figure 4 illustrates the implementation of the current design that can be referred to as "turning to the right", or the rider leaning to his right.

The connecting rod 306 can transfer these rotational motions to the fixed arm 304 and the elastic material 301 that can be partially deformed. Represents the amount of deformation of the joint or joint or intersection between the elastic material 301 and the bottom plate 303 at the element symbol 401, which is directly related to the following: the hardness or stiffness of the elastic material, the application to The tightness or moment of the first bracket 103 of the fastening bolt, the length of the connecting rod 306, the length of the swing arm 113, and The magnitude and direction of the force applied to the handle 110 by the user. The elastic material will eliminate some force generated by moving the handle 110, and changing the structure or size of these elements may change the operation of the device and the "feel" of the simulated riding experience.

The force that has not been eliminated by the elastomer material can continue to remain in the frame 102, resulting in the steering of the bicycle. The design of the present invention can modify the generated horizontal and vertical offset, and therefore, by changing the hardness or stiffness of the elastic material, the moment applied to the first bracket 103 of the fastening bolt, that is, compressing the elastic body material , The effective length of the connecting rod 306, the effective length of the swing arm 113, the magnitude and direction of the force applied to the handle 110 by the user, and the positioning of the body mass can customize the riding simulation experience.

The design of the present invention generally does not provide a change in the alignment of the main shaft 203 formed by the two mount position points without substantially different riding experience. However, it can be seen that changing the alignment spindle 203 can change the riding simulation experience. In fact, the experiment showed that the angle of the main shaft 203 in the range of about 30 to 45 degrees from the level measured relative to the two mounts 103 and 104, and in some cases 37 degrees, plus Increasing or subtracting 8 degrees will produce a substantially appropriate simulated response when performing a bicycle fitness exercise on the bicycle fitness exercise device 100. Other angles can be used, and various factors of these angles are very relevant. These factors include but are not limited to the size and dimensions of the frame 102, the position of the pedal 106 and the seat 115, etc., but the operation in these ranges seems For most people on the device reflecting this specific example, an accurate riding simulation experience can be provided. In this configuration, the design of the present invention can In order to allow the user to perform bicycle fitness exercises, the horizontal and vertical movements exhibited by the bicycle frame suspended within the fixed frame can closely simulate the operation of a traditional bicycle.

In addition, the design of the present invention can use various elastomer materials to provide a method for gradually increasing resistance when subjected to steering force. Each material exhibits a different hardness in terms of hardness measurement to adjust the The frame 102 within the fixed frame exhibits horizontal and vertical movements that deviate from the main axis, and allows adjustment of the amount or angle of forward tilt, leaning, forward and backward rocking, and horizontal rocking to improve the accuracy and reality of bicycle fitness simulation sex. The term "hardness measurement" is generally used to indicate the resistance of elastomer materials to deformation, and the hardness measurement of elastomer materials can be changed to create different riding qualities.

FIG. 5 is an exploded view of the design of the first frame 103, which illustrates many elements in FIG. 3 and FIG. 4 from another perspective view. Referring to Figure 5, the handle 111 is shown protruding away from the bottom of the head assembly collar 501, which is mounted on the frame 102 inside the head tube frame element, as a part of a typical head assembly . The illustrated swing arm 113 is coupled with an integrated clamp 502 device, which allows the swing arm 113 to be fastened to the handle 111 while maintaining a fixed relationship.

In this example, the connecting rod 306 is used to attach the swing arm 113 to the fixed arm 304, allowing the connecting rod 306 to be shortened or lengthened. In this configuration, according to the design of the present invention, the connecting rod 306 shown includes two threaded eye bolts, and a nut system is constructed to increase or decrease the gap between the swing arm and the fixed arm. The measured distance between. The first A threaded eyebolt is shown as a female eyebolt 503 element, which at one end supports an inner sleeve 503A such as elastomer, metal, plastic, etc., wherein the bolt 506 can pass through the sleeve 503A center of. Once the eye bolt 503 is passed through the sleeve 503A, the bolt 506 can pass through the center of a plurality of holes 511 seated on the swing arm 113. After the bolt 506 successfully passes through a hole in the swing arm 113, it can then pass through the hole 512, and a nut 507 can be screwed to the bolt 506 to fasten the swing arm to the connecting rod 306 Mother ring bolt 503. It can be noted that the sleeve 503A can allow the eye bolt 503 to rotate concentrically around the bolt 506, and allow a movable pivot point in the horizontal direction to be formed at the junction of the swing arm 113 and the connecting rod 306.

In this example, the female eye bolt 503 shown has an internal thread at the other end, which is positioned to match the male eye bolt 508. The male eyebolt 508 shown is threaded with an external screw die, which is positioned for assembly with the female eyebolt 503. Before assembling with the female eyebolt 503, installing the adjusting lock nut 504 on the male eyebolt 508 can allow changing the position of the adjusting lock nut 504 along the threaded shaft of the male eyebolt 508 To change the effective length of the connecting rod 306 measured between the swing arm 113 and the fixed arm 304. Seating the adjusting locking nut 504 further toward the sleeve 508A of the male eye bolt 508 can shorten the connecting rod, and seating the adjusting locking nut 504 further away from the male eye bolt sleeve 508A can lengthen the connecting rod. In other words, by rotating the male eyebolt clockwise or counterclockwise relative to the female eyebolt, the effective length of the connecting rod can be shortened or increased. Those who are familiar with the technology should A good understanding of the use and manipulation of eye bolts to form connecting rods with adjustable lengths.

Continuing, the second eyebolt element shown as a male eyebolt 508 supports an inner sleeve 508A, such as elastomer, metal, plastic, etc., at one end, where the bolt 509 passes through the center of the sleeve 508A . Once through the sleeve 508A, the bolt 509 will pass through the center of the hole 304A on the fixed arm 304. After the bolt 509 successfully passes through the hole in the fixing arm 304, a nut 510 can be screwed onto the bolt 509 that fastens the fixing arm 304 to the male eye bolt 508 of the connecting rod 306. It can be noted that the sleeve 508A can allow the eye bolt 508 to rotate concentrically around the bolt 509, while allowing a movable pivot point in the horizontal direction to be formed at the junction of the fixed arm 304 and the connecting rod 306. Furthermore, the movable pivot position formed by the sleeve 508A, the eye bolt 508, and the bolt 509 can exhibit a small amount of vertical rotation, as generally exhibited by the ball joint design, allowing movement in the vertical direction. Pivot position point.

The fixed arm 304 shown is fastened to the top plate 302 by welding, glue or other methods (not shown in the figure) to fix the two elements in place. The top edge of the elastomer material 301 may be seated on the bottom side of the top plate 302 and positioned above the installation hole 515. In a similar manner, the bottom edge of the elastomeric material 301 may be seated on the top side of the bottom plate 303 located above the mounting hole at 516. When the above components are aligned, a bolt 517 can pass through the washer 518, the mounting hole 515, the elastomer material 301, the mounting hole 515, and the washer 519. And finally fastened by the nut 520.

It can be noted that the top plate 302 is attached to a section 105 used to construct the fixed frame 101, and the bottom plate 303 is attached to a top pipe frame element used to construct the frame 102.

Figure 6 is a right side perspective view of the user who is riding on the device in a right-turned position, and by leaning, tilting, and rotating the bicycle frame while simultaneously applying a compound control input force to the handle and seat And the pedal to spin the pedal. Figure 6 illustrates the fixed frame, bicycle frame, drive line, handling, seating, and mounting point components used to construct the design of the present invention. Each component has been described above.

FIG. 6 illustrates that the rider 600 makes a right turn on the bicycle fitness exercise device 100 and the frame 102 is pivoted relative to the first frame 103 and the second frame 104. The handle 110 is turned or rotated clockwise as indicated by the arrow 601, and the frame 102 is pivoted as indicated by the arrow 602. As shown in the figure, the rotating system at the handle rotates the adjustable collar 114 and allows the connecting rod 306 to push against the fixed arm 304. In this configuration, the bicycle frame 102 can rotate relative to the main shaft 203 and lean to the right. As a result, the movement in the direction indicated by the arrow pivots relative to the first frame 103 and the second frame 104 about the main shaft 203 as indicated by the arrow 603. This ability to lean or pivot the bicycle frame relative to the two frames provides a unique experience, especially when compared to previously available designs for stationary or spinning bicycles.

In such an operation, the user can first stand on a pedal Use the design of the present invention on the board and on the frame 102 and sitting on the seat. The user can drive in the standing position as shown in FIG. 6 or in the sitting position by simultaneously turning on the pedals, balancing the bicycle frame, steering the handle, and leaning over the seat. When the frame 102 pivots around the first frame 103 and the second frame 104, the user can lean to the right or left at a certain position for the required amount. At this time, the device that includes the seat is attached. Tilt to the side. As can be seen, the section 105 of the fixed frame 101 shown in FIGS. 1 and 3 is fixed in this example, just like the plate 302, and the bicycle frame 102, including the mounting bracket 307. And tilt. As a result of this inclination, the design of the present invention results in the handle lever 111 fixed to the swing arm portion 113, the bolt arrangement 306, and the fixed arm 304 can provide a level of handle rotation due to the torque caused by the arm portion. In other words, the tilt of the frame 102 generates a rotating force applied to the handle 111, thereby turning the handle and the handle attached to the handle. As a result, the handlebar is tied to turn in the proper direction when tilted, so that the rider can ride without putting his hands on the handlebar and causing the handlebar to turn or pivot. Generally, the user puts his hand on the handle and actively rotates the handle to tilt and position the bicycle frame 102.

The design system of the present invention is set to generally produce a balance position point in terms of the body mass position and the angle of the main shaft 203. Too little resistance may cause rapid leaning to one side even with very slight leaning, which may cause the user to fall off the bicycle. Too much resistance may prevent the rider from leaning over. Generally speaking, the rider has a body mass center position, and the center position indicates that when sitting upright or leaning forward and holding The handle provides the perception of turning relative to the main shaft. Changing the size of the design of the present invention may result in a change in the ratio of turning for leaning. Among them, the current bicycle frame articulated pivot system provides a steering response and the tilt of the frame 102.

Especially when the rider leaves the bicycle, since the steering device of the handle includes a swing arm 113 and an adjustable collar 114, applying pressure or torque to the handle of the present invention may cause the bicycle frame to tilt. A more practical application of this feature is that because the increased force is applied through the handlebars, the rider can lean his body and apply pressure to both the handlebars to "lean into" a turn, thereby As a result, the described turn or lean can be constructed more quickly. In addition, the seat 115 can receive pressure from the rider's thighs or buttocks, and by applying torque above the main shaft 203, such pressure can increase the tilting effect of the bicycle design.

The handle of the example in FIG. 1 is attached via the adjustable collar 114 and the swing arm 113, but these elements can be omitted or disconnected, causing the handle to twist freely or be fixed, like being welded to a pipe. Component 130. The combination of the pedaling (driving pipeline) mechanism and the manipulation input relative to the main shaft 203 results in the perception of movement or the design of the present invention is used to simulate the riding of a bicycle. The design of the present invention provides a leverage point similar to that of a traditional bicycle, in which the polar moment and the polar moment of inertia are generated relative to the position of the body mass and the angle principal axis. With the current design, due to the relationship between the element and the resistance force, such as those produced with the elastic body 301, the user can easily restore his right side to the center or neutral position when leaning. Location.

The placement of the first frame 103 and the second frame 104 depends on the required performance, the components used, and the position of the spindle 203. Generally speaking, the placement of the main shaft 203 can be regarded as a placement relative to the rider, which is generally close to placing or positioning a front wheel on a conventional bicycle.

Figures 7A, 7B, and 7C illustrate a "manipulation" or handle lockout mechanism for use with the design of the present invention.

Fig. 7A is an enlarged view illustrating the blocking mechanism connected to a front suspension position point of a first frame, the first suspension position point of the first frame involves an elastomer spring attached to a control input assembly 201 device and a pinch bolt device that can be used with the design of the present invention. Generally speaking, according to an aspect of the design of the present invention, the pinching bolt device can be positioned to fix the geometric relationship, that is, to maintain substantially parallel, formed on the top part matching the elastomer spring 201 And between the bottom plates, and it is enough to prevent the spring from deforming. The squeezing bolt device can be constructed of steel or other materials sufficient to prevent the spring from being deformed. Figure 7A illustrates an example of a lockout mechanism that involves one half of a two-piece cylindrical collar at symbol 701. The collar is constructed to have symbols at 702 and 703. The two bolts are used to attach the two pieces together to form a strong fixed collar. In the "locked-out" position, the design of the present invention can fix the manipulation input assembly, which is sufficient to prevent the user from turning the handle 110 and can prevent any tilt of the frame 102.

Due to the buckling of the materials used and the tolerances of the device assembly, the locking mechanism is set in the "locked-out" position to manipulate the input components, The frame and other elements can exhibit a small amount of movement. This small amount of movement can provide a suspension mechanism in the blocked position, that is, the design of the present invention can combine the suspension mechanism with a simulated stationary pedal bicycle, that is, there will be no manipulation input from the user . The combination of a suspension mechanism and a fixed pedal bicycle is currently not available in a completely rigid fixed design.

The design of the present invention may include a mechanism for fully locking or fully releasing the frame 102 to provide the experience of the rigid fixed bicycle or bicycle fitness exercise device 100, respectively. Referring back to FIG. 1, a pin or rod device (not shown in the figure) attached to the seat tube 209 can, for example, fall downward through a sleeve between the pedals 106 and be inserted into a seat Hole in section 105. The pin is completely inserted into the hole to lock the frame and the frame 102 can be fixed enough to simulate a typical stationary bicycle. According to the design of the present invention, retracting the pin device from the hole seated in the section 105 allows the frame 102 to rotate relative to the main shaft 203. Constructing the pin device between the pedals can eliminate possible interference when the frame is completely released and can be moved. In a preferred embodiment, the pin device will be attached to the frame 102, in fact, as far away as possible from the first frame 103 to reduce the stress applied to the frame 102 when it is fully locked. Other locking mechanisms that basically lock or inhibit rotation of the frame can be used.

FIG. 7B is an enlarged view of the deformation of the suspension position in front of the first stand during the use of the bicycle fitness exercise device 100 when the bicycle fitness exercise device 100 is built in the "unlocked" position. When in the unlocked position, the user can apply force on the pedal, seat and handle, which is sufficient as shown in Figure 7B Ming's deformable elastomer spring 301. Compared with the distance measured at the position point 706, when viewed at the position point 705, the deformation of the elastic body can change the distance between the top plate 302 and the bottom plate 303. In this embodiment, the distance at the position point 705 is greater than the distance at the position point 706, and the bicycle fitness exercise device 100 is tilted due to the elastic body spring 301 being deformed under the influence of the dynamic force applied by the user. FIG. 7B illustrates that the frame 102 is tilted or deflected by a certain amount at the position point 707. FIG.

FIG. 7C is an enlarged view showing no deformation of the suspension position in front of the first frame during the use of the bicycle fitness exercise device 100 when the bicycle fitness exercise device 100 is built in the "locked" position. In the locked position, a cylindrical collar 710 is positioned and constructed to maintain the "stationary" or "static" shape of the elastomer spring. When present or "locked", the blocking mechanism keeps the top plate 302 and the bottom plate 303 in a fixed parallel configuration. When constructed in the "locked" position, the bicycle fitness exercise device 100 is tied at a position 711 to maintain a fixed distance between the plates.

The illustrated chain 820 is shown as "entering page" at the top of the clutch plate configuration 802 and the chain is shown as "off page" at the bottom of the clutch plate configuration 802. When the user operates the pedal and the chain in a clockwise direction (when viewed from the right side), the clutch plate, or "dogs", is configured to contact and interfere with it, enough to operate the flywheel 108 . When the pedal and the chain are operated in a counterclockwise direction, the clutch plate or puller s is configured so as not to contact or interfere, and is sufficient to allow the pedal 106 to spin freely without affecting the flywheel 108.

Figure 8B is a close-up view illustrating a reversible flywheel device that involves a direct drive mechanism 805 attached to the flywheel 108, which is configured to operate a flywheel that can be used with the design of the present invention. Referring to the right hand side of FIG. 8B, the direct drive mechanism 805 may include a fixed plate configuration 806, which is attached to the flywheel 108 using bolts 807 and 808. The chain 820 shown is tied "into the page" at the top of the fixed plate configuration 806, and the chain 820 shown is tied "out of the page" at the bottom of the fixed plate configuration 806. The bolts at the symbol 807 and 808 can allow the flywheel 108 to continuously contact and engage with the fixed plate arrangement 806 to move and operate as a single component. When the user operates the pedal and the chain in a clockwise or counterclockwise direction, the design of the present invention is to spin or rotate the flywheel 108 in the same direction as the pedal and the chain.

An additional embodiment may involve the handle bar 912 passing through the top of the head tube frame element and protruding away from the bottom of the frame element. In this configuration, the other end of the handle 912 can be attached to an adjustable swing arm assembly 917, wherein the swing arm assembly 917 can be set in a fixed position by locking an adjustable collar.

The handle 912 can be configured to apply dynamic control force input by the user connected to the handle 909, and convert these forces received at the handle 909 to the first stand 910, for example, a multi-element installation located under the handle 909 Set up device. Most of the force can be transmitted from the handle 912 or the manipulation connector tube 914 to the first frame 910, and a small amount of force can also be transmitted to the second frame 911.

In the design of the present invention, the seating assembly can be attached above the driving pipeline assembly at the lower pipe frame element of the frame 902, as shown in FIG. 9. The seat component can support the seat 908, or the car seat, and can provide users with a place to place their upper legs and contact their upper legs with the core to help while performing simulated bicycle fitness exercises. The balance of the frame 902 suspended in the fixed frame 901 is maintained. The seating assembly may include a seat 908 fixed to the seat post 918, which is sufficient Provides a sitting posture that allows the user to properly position their body on the frame 902 and provides additional manipulation force input to further lean and steer the frame 902.

The seat component can be used together with the drive line component and the control component to help the user maintain balance while rotating the pedals to perform a simulated bicycle fitness exercise. The design of the present invention can fix the seat 908 to one end of the seat post 918 by tightening the clamping mechanism at 919. The other end of the seat post 918 is generally fixed to the lower tube frame element portion of the frame 902 by tightening the adjustable collar at the element symbol 920. The bicycle fitness exercise device may be configured with a seat post 918 to connect the power control input applied by the user at the seat 908 and transfer these forces to the second frame 911. Again, although most of the force can be transferred from the seat post to the second frame, small forces can also be transferred to the first frame 910.

The connection configuration and the force transfer from the pedal 904, the seat 908 and the handle 909 in this embodiment are similar to the design of the present invention described above, and will be further explained according to the following drawings.

Fig. 10 is a left side view illustrating the angular relationship between the first (lower front) frame and the second (upper rear) frame formed around the main shaft. The first frame 910 may include a load distribution configuration, such as a multi-link elastomer spring device 1002, which is configured to attach and suspend the frame 902 within the fixed frame 901 at a forward position. The first frame 910 shown in FIG. 10 includes a pin 1004 with a housing 1005, which is configured to attach and suspend the frame 902 within the fixed frame 901 in a forward position Place. The second mount 911 may include a similar pin with a housing configuration.

The load-distributing, multi-linked elastomer spring-yellow device shown is related to the front lower frame location point, but such devices or similar devices can be connected to the upper frame location point (second frame 911). In addition, although the orientation of the bracket position points shown is at different predetermined distances above a surface such as a floor or an upright or flat ground, it should be understood that when the bracket position points and the main axis formed thereby are The function described in this article can be achieved when the value of the level change is included.

These two frame position points, together with the user input provided at the pedal 904, the seat 908, and the handle 909, can allow the fixed frame 901 to move forward or move away from the main shaft 1001 of the frame 902. Section pivot. The ability of the frame 902 to pivot and rotate in the space defined by the position of the frame fixed to the fixed frame can significantly and more accurately simulate the riding of a bicycle, and the load is distributed and the connection is flexible. The use of the body spring device can prevent the wear of the parts provided therein.

The frame 902 may use a multi-linked elastomeric spring device 1002, which incorporates a pin configuration 1003 with a housing. However, such a stand may include a hydraulic strut or other components suitable for providing suspension and spring elements designed in accordance with the present invention. The first and second brackets 911 may involve a separate pin with a housing device, which is assembled to form a front and rear suspension point for the frame 902. Generally speaking, a pin member with a housing can connect the frame 902 to the fixed frame 901.

A pin part with a shell can suspend the frame 902 and allow a suitable When defining a point or pivoting or rotating movement of the main shaft 1001, where the main shaft 1001 is established via the first and second mount position points. The design of the present invention is not limited to the use of pin parts with shells at the position of the first and second brackets, and any device or part that can produce a certain range of movement or pivot around the position of the bracket can be used. It is sufficient to provide the function exhibited by the structure of the pin with the shell. The use and assembling of the pin part with the housing that suspends one component from another component can be thoroughly understood by those having ordinary knowledge in this technical field.

The term "elastomer" used in this article is generally used to describe a material formed by using vulcanized rubber, but other resistant materials can be used as resistance elements, and load distribution can be achieved by one large part or multiple small parts. Parts or structures are provided as a non-elastomeric body that can distribute the load while providing excellent bicycle simulation performance. The term elastomer is not intended to be limiting. The actual elastomer material can tolerate considerable movement when subjected to external forces. Generally speaking, elastomeric materials are characterized by their ability to deform when subjected to an external force and return to their original shape when there is no external force. The ability to buckle or deform and return to their original shape can provide a spring-like resistance effect. The spring effect exhibited at the first stand and the pivoting action exhibited at the second stand, when aligned along the main axis 1001 and combined with the previously described assembly, allows the user to rock back and forth And swing the frame 902 horizontally, and simulate turning at one angle, that is, generated from the user's forward tilt, turning, and a combination of these. At the same time, this second embodiment produces a kind of difference when pedaling pedals to simulate a bicycle fitness exercise. "Feedback from the road" has a similar steering effect. The spring-like resistance effect can involve any type of spring device that is adapted to perform the function of the first or second stand by allowing the frame 902 to return to a neutral position.

The terms "pivot", "roll", "roll", "yaw", "lean", and "tilt" are like The foregoing is generally used in this disclosure, and is used to describe the horizontal and vertical movement or angular offset of the frame 902 within the fixed frame 901 and around the described main axis or element.

Figure 10 illustrates the assembled bicycle fitness exercise device 900, which includes a fixed frame 901, a frame 902, drive lines, control, seating, and stand position point components; it is constructed to allow the user to use a circular shape The pedal 904 (only one pedal is shown in the figure) is operated by the rotating or rotating action of the pedal, and is configured to help the user maintain a balance while performing a simulated bicycle fitness exercise.

The handle 909 can receive a force derived from the user's hand, such as turning left, and connect or transfer the force to the frame 902 through the handle 912. In addition, the force may be derived from the user pushing on the side of the seat 908, for example, pressing down the upper left leg or the area of the thigh, and the force may be transferred to the frame 902 through the seat post 918. Furthermore, the pedal 904 can receive the force from the user's feet, and can connect the force to the frame 902 through the drive line assembly. The force received by the frame 902 can disappear due to the following reasons: the suspended bicycle frame is connected to the elastic body around the front frame seat combined with the pin frame seat position point device 1003 with the outer shell. The spring device 1002 is used for forward tilting, tilting, shaking back and forth, horizontal shaking or joint pivoting within the space defined by the fixed frame 901.

The force elimination mechanism between the frame 902 and the fixed frame 901 may involve the construction of a bracket position 1003 with a front pin of the housing, including a multi-connected elastomer spring 1002 device to form the first bracket 910, wherein The front frame seat pin with the outer shell device is positioned and aligned along the main axis 1001 with the rear frame seat pin with the outer shell device. The rear frame seat pin with the outer shell device forms a second frame seat 911, as shown in FIG. 10 .

The force transfer mechanism enables the design of the present invention to transfer the force while the user applies force to the handle 909, the pedal 904 and the seat 908, and can allow the bicycle fitness exercise device to absorb, distribute and disperse the source It comes from the force generated by the user while pedaling, turning the handle, and maintaining balance. In other words, the design of the present invention can transform the force applied to the handle, pedal and seat into the force absorbed and dissipated by the frame 902 in the form of front and back shaking and horizontal shaking, thereby generating a frame 902 relative to the fixed frame 901 Movement from side to side. The bicycle fitness exercise device 900 is related to the transfer of force from the crank arm 905, the handle bar 912, and the seat post 918 to the components that constitute the first frame 910 with the multi-linked elastomer spring 1002 is shown in FIG. 11 And discussed below.

The angular relationship formed by the movement of the first bracket 910 and the second bracket 911 relative to the main shaft 1001 along the main shaft 1001 can be described in conjunction with the combination of horizontal and vertical components used in this design. The horizontal offset component can be a stop or static in the space established from the fixed frame 901. It is generated by the frame 902 moving in the horizontal direction when measuring at the state position. The vertical offset component may be generated by the frame 902 moving in the vertical direction when measured from a stop or static position within the space established by the fixed frame 901. The angular relationship caused by the user's input such as turning the handle and/or pressing the thigh into the seat, etc., that is, forward, tilt, forward and backward rocking, horizontal rocking, or any combination of these The amount can be described by dynamically changing the horizontal and vertical offset caused by the frame 902.

The angular relationship formed between the two bracket positions combined with the structure of the installation device can produce a control effect and allow the tilt-to-turn ratio to be changed, that is, relative to the two The joint pivots at the position of each frame are used to closely simulate the experience achieved when operating a traditional bicycle. The tilt-to-steer ratio can be produced by the combination of the user moving the handlebar and leaning against the seat and lifting or pushing against the pedal. In this configuration, the design of the present invention can allow the user to steer at an angle that is obtained when operating a conventional bicycle in a similar manner.

The control effect or force generated by the design of the present invention can provide a realistic "feedback from the road" as analog information, which is transmitted like the reaction force received by the user at the handle, seat, and pedal. The user can process the simulation information generated by the design of the present invention to determine the magnitude and duration of the required force. The simulation information is provided as input to the handle, pedal, and seat, as if it were sufficient for simulation The continuous adjustment of the way of controlling and maintaining balance while exercising on bicycles is provided.

The pin is generally installed inside the housing supported by the bearings 1101 and 1102. The pin can support a screw pile structure with threads. The threaded pin can pass through a bearing 1101 before passing through the fixed frame 901, that is, the pin 1004 can be supported in the housing 1005 by the bearings 1101 and 1102, and double The "locking" nut 1103 is configured to be fixed or tightened. A support flange 1113 engaged with the frame 902 can be positioned between the housing 1005 and the lock nut 1103, and attached by passing the pin 1004 through a hole 1115 in the support flange The attachment is fixed to the frame 902, which is sufficient to allow pivoting and rotation about the attachment point.

The fixed frame member 1104 may be attached to other fixed frame members 1116 to form a fixed frame 901. At the other end, the frame member 1104 can be attached to the manipulation connector tube 914 via the swing arm 917, as described above. In this embodiment, multiple elastomer springs, forming a distributed load configuration, can be provided to form a front frame seat suspension mechanism. FIG. 11 illustrates an embodiment that uses three elastomer spring devices combined with a pin having a housing member to form the first bracket 910, but more or fewer load dispersing elements or different configurations of load dispersing elements may be used.

The right elastic body spring device 1105 can be installed in a self-positioning seat holding cup at the fixed frame 1104 via a holding bolt 1106. Self-positioning can be achieved by using a lip that surrounds the circumference of the holding cup. However, other self-positioning mechanisms can also be used, such as a positioning pin in a spring, which is installed in the building to receive a predetermined position of the positioning pin. Position in the hole. In a similar manner, the left elastomer spring device 1107 can be joined to a self-positioning seat cup at the fixed frame member 1104 via the retaining bolt 1108.

The design of the invention may include a central elastic body spring device 1109, which is positioned between the right elastic body and the left elastic body according to the design of the invention. Each elastomer spring device can be positioned and held in position using an installation top positioning cup with an integrated threaded installation screw, so as to correctly position and align the springs relative to each other, or an elastomer spring. It should be noted that the central elastomer spring does not have retaining bolts similar to those provided to the left and right springs. In this embodiment, the central spring is formed by the left and right springs and their related The combination of the holding mechanism and/or the bolt is held in position.
