In the present invention, the arm exercise frame 26 having the arm exercise unit 28 is attached to the treadmill frame 22. In a preferred embodiment of the invention, as described below, the arm exercise frame 26 is detachably attached to the treadmill frame 22 so that it is adjustable in the width direction and can be applied to treadmills of various sizes. ing.

【0013】

The arm exercise unit 28 has a pair of poles 30, 30 and is attached to the side surface of the treadmill frame 22.

【0014】

Thus, in the preferred embodiment of the present invention, the arm exercise frame 26 is detachably attached to the treadmill frame 22, but the arm exercise frame 26 is detachably attached in this way. This is to facilitate the attachment of the arm exercise frame, which is adjustable in the width direction when clamped to the treadmill frame 22.

【0015】

As shown in FIGS. 6 and 7, the arm exercise frame 26 has a pair of base members 32, which have an inverted U shape. The tube 34 is firmly connected to the leg of the base member 32 by welding, and the number of fixed tubes is four. A telescopic tube 36 is inserted into a fixed tube 34 in parallel to allow the base members 32 to move closer and further apart from each other so that the width of the frame 26 is adjustable.

【0016】

Each base member 32 has a plate-shaped mounting bracket 38, which has a vertical plane 40 and a horizontal plane 42 that is vertically bent inward. The horizontal surface 42 is in contact with the frame 22 of the treadmill 12. As shown in FIG. 9 for clarity, the hinge shaft 44 extends vertically outward from the vertical plane 40 of the bracket 38. The shaft 44 may be in the form of a rod with a smooth interior and threaded ends.

【0017】

An L-shaped mounting member 46 is fixed to the inside of the bracket 38, and is mounted on the top of the U-shaped base member 32. The treadmill frame 22 has a vertical wall 48 parallel to the mounting bracket 38. The vertical wall 48 ends at the flange 50, which is folded inward. The U-shaped bracket 52 is loaded on the flange 50. The bracket 52 has a hole 54, which is in line with the hole 56 of the L-shaped blanket 52. The bolt 58 extends through a row of holes and uses nuts 60 to secure the bracket 46 and flange 50 together. At the same time, the arm unit frame 26 is detachably attached to the treadmill frame 22. From the viewpoint of stability, a pair of U-shaped brackets 50 are provided on each L-shaped bracket 46.

【0018】

Further, an L-shaped bracket 62 is prepared to detachably fix the frame 26 to the treadmill frame 22, but this bracket 62 is fixed to the base member 32 by welding and is used for the treadmill. It is detachably attached to the flange 50 of the frame 22, which is done by a suitable fastener, for example a bolt 64 with a fixing nut. The L-shaped bracket 62 is shown, for example, in FIGS. 1 and 7.

【0019】

The pole 30 is rotatably attached to the hinge shaft 44, for example, as shown in FIG. 9, and the brake disc, i.e., the resistance plate 66, is attached to the shaft 44, as shown in the figure. It is located between the disc member 68 fixed to the pole 30 and the bracket 38. The contact angle between the pole disc member 68 and the resistance plate, i.e. the disc 66, is determined by the amount of force the user requires to swivel each pole during arm exercise.

【0020】

Further, as shown in FIG. 9, the knob 70 is screwed to the outer end screw portion of the shaft 44, and a boss 72 threaded inward is provided inside the knob 70. Used for connection with shaft 44. The boss 72 extends through a cup-shaped housing 74 mounted opposite the bracket 38, which housing 74 has a slot 76 into which the pole 30 is extended.

【0021】

A key washer 78 is provided on the shaft 44 between the boss 72 and the pole 30, which has a rectangular or slotted opening with a pair of spring washers 80 facing each other. There is. Subsequently, the flat washer, the thrust bearing, and the flat washer are attached to the shaft 44 in this order, and face the U-shaped extension portion 82 extending from the pole disc 68.

【0022】

Similar to the frame of the treadmill 12, the arm unit frame 26 is firmly fixed and operated by a clamp method to the frames of leg exercise units of various sizes. The frame 26 is originally arranged below the frame of the exercise device 10, and by increasing the width, the frame 26 moves left and right to provide a pole 30 corresponding to the user's arm.

【0023】

The clamp mechanism is designed to provide a very strong fit and resist forward and backward movement, without compromising the effectiveness of the exercise if the user uses the pole 30 beyond a fixed range. , Can move smoothly.

【0024】

What the user must do if he wants to adjust the force required to move the pole 30, that is, the resistance, is to rotate the knob 70 clockwise or counterclockwise to increase the resistance. Or reduce it.

【0025】

Figure 2 shows that the pole 30 is at the solid and alternate long and short dash lines during arm exercise.

【0026】

Another feature of the mounting bracket 38 is that it has multiple slots 84, which extend to the top wall 42 and front 40 of the mounting bracket 38. The function of slot 84 allows the pole to be fixed and mounted in the desired orientation, which is the case, for example, when the user exercises the legs without exercising the arms. Allows the user to have a balancing function. In order to achieve this adjustable mounting condition, each pole has a sliding retaining ring 86, and the user operates the retaining ring 86 to freely rotate and raise and lower the pole 30. Can be done. Retaining ring 86 includes a T-shaped pin 88, which is sized to accommodate a T-shaped slot 84. If there are four slots 84, four types of position settings are possible. The number of set positions can be changed according to the number of slots 84.

【0027】

If the pole is to be dormant or locked in a fixed position, the user arranges the lock pin 88 in line with the desired slot 84 by rotating the retaining ring 86 and turning the pole 30. .. The user then slides the retaining ring 86 onto the pole 30 and lowers it, placing the lock pin 88 in the proper slot to prevent any rotational movement of the pole 30. FIG. 8 shows an enlarged view of the lock pin 88 set in the T-shaped slot 84.

【0028】

A further feature of the present invention is that it has various adjustment functions for the length of the pole 30 and the inclination angle of the place where the user stands.

【0029】

As illustrated in the figure, the pole 30 has an outer tube 90 and an inner tube 92 that are telescopically positioned. The column of holes 94 is arranged so as to surround the surface of the outer tube 90. The various columns are zigzag-arranged with each other, giving them greater selectivity. The inner tube 92 has a spring-loaded lock pin 96, which is capable of engaging the selected hole 94. For example, in pole 30 shown in FIG. 1, the lock pin 96 is in the highest hole 94. By surrounding the surface and providing a series of holes, it is possible not only to adjust the height of the pole 30 but also to change the tilt angle. In consideration of this, the pole 30 has a bent portion 98 with a foam grip 100, which improves comfort when using the pole. The bends on the pole 30 provide an ergonomically superior design. Since a series of holes are provided so as to be separated in the vertical direction and also in the outer peripheral direction, it is possible to adapt to various body types of users and various exercise machines by expanding and contracting the pole 30. ..

【0030】

A further feature of the apparatus 10 of the present invention is that it has an electronic data reading mechanism 102, which allows the user to read various data indicating the type of exercise. This device is well known and has, for example, a timer, a speed indicator, a speed selector, a reset device, a stop device, and other well known indicator means. As shown, the reading unit 102 is attached to the upper end of a column 104 that is rotatably attached to the frame 22 using a pivot pin 104. The electrical wiring 108 used for the reading unit 102 is shown, for example, in FIG. 6 or FIG.

【0031】

FIG. 7 also shows the appropriate sensor 110 mounted on the frame 22. The flywheel 114 has a magnetic member 112, which is detected each time it passes through the sensor 110 and is used to count the number of revolutions of the flywheel 114, whereby the user uses the treadmill 12. It is possible to read the indicated values of speed and / or distance at the time of.

【0032】

A further feature of the present invention is that it has adjustable legs 116 at the front end of the frame 22. The leg portion 116 may have an appropriate shape, and for example, the inner tube 120 may be flexibly attached to the outer tube 118. The outer tube 118 has a pair of linear openings for inserting the lock pin 122, and the inner tube 120 has a series of vertical holes extending through the interior. The lock pin 122 is extended by inserting the hole of the fixed tube 118 and the hole of the inner tube 120, whereby the height of the leg portion 116 can be adjusted. To facilitate the operation of the lock pins 122, the ring 124 is provided so that it can freely rotate through the holes provided in each lock pin 122. A wheel, or roller 126, is provided at the lower end of the leg 116 to facilitate movement of the device 10. At the rear end of the treadmill frame 122 is a pair of fixed legs 128 having a pad 130 made of rubber or other suitable material.

【0033】

If you want to store the device 10, you can operate it in several places to make it compact enough to be easily transported. For example, the pole 30 can be operated to accommodate the entire inner tube 92 in the outer tube 90. Then, when the pole 30 is rotated, it can be arranged along the side surface of the treadmill frame 22. Loosening the nut at the end of the threaded hinge pin 106 for the stanchion 104 allows the stanchion 104 to rotate with respect to the belt 14. The leg 116 can be operated to insert the entire inner tube 120 into the outer tube 118. When compacted, the user can grab somewhere on the frame 22, for example the roller 16, lift the folded unit, or rotate and move the wheels or rollers 126.

【0034】

As described above, a preferred embodiment of the present invention is to provide a removable arm exercise unit, more specifically, the arm exercise unit 28 is adjustable in the width direction and is extant. It is to be freely attached to a leg exercise unit, for example, a treadmill 12.

【0035】

Further, by applying the present invention, the arm exercise unit can be firmly attached to the leg exercise unit rather than being removable. This is because such a fixed mounting means has a simpler structure and eliminates the need for those required for width adjustment and other parts required for being removable. However, such means of the present invention do not have the advantage that they can be detachably attached to and applied to any leg exercise unit.

【0036】

In addition, while the user is doing leg exercises or other aerobics exercises, the pole 30 is used alone to balance the user, but in this case both of the two poles. It is not necessary to arrange them in the same direction.

【0037】

Further, the inclination angle of this pole can be changed by selecting various slots 84 and engaging with the lock pin 88. Similarly, the direction of rotation of the pole and the length of the pole can be changed from each other, which is done by the lock pin 96 selecting an appropriate hole.

【0038】

As described above, the arm exercise device according to the present invention provides a unit that can be attached to an aerobics exercise machine and is used for upper body or whole body exercise. It should be noted that such aerobics exercise machines are not limited to treadmills, but may be other devices such as XC (cross-country) schema scenes, bicycles and steppers. The arm exercise unit is applied and fixed or removable to be attached to such an aerobics exercise machine.

【0039】

If the present invention is widely applied and the arm exercise unit is detachably mounted, the removable mounting device can have one or more removable brackets or posts, which are the handlebars, It can be attached to handlebar posts, bike frames, side frames for treadmills, front frames for treadmills, rear frames for treadmills, stepper handrails, stepper frames, or base plates for aerobics exercise machines.

【0040】

Also, as mentioned above, the pole 30 is fully adjustable, which is done by changing the height and orientation for proper balance and when used in arm exercises. This is because the direction of the pole can be changed freely.

【0041】

It is advantageous to have one or more tension regulators, which diversifies the load range of the adjustable exercise. With the pole function and, above all, the function of the top handle that can be fully rotated 360 degrees and fixed in multiple positions, it is applicable to a wide variety of users and therefore has the comfort and atmosphere that suits individual needs. It is possible to make it.

【0042】

The pole according to a preferred embodiment of the present invention has a bent portion at an end portion. However, the present invention is applicable even when the pole is perfectly straight.

【0043】

In addition, the device 10 is not only an effective whole body exercise device, but also provides a device that is convenient for transportation and storage. This is achieved because the poles and stanchions that are adjacent to, that is, in contact with, the treadmill can be folded.

【0044】

Adjustable legs 116 at the ends of the frame 22 provide a ready position for the wheels and not only facilitate transport when the device 10 is in the folded shape, but also the legs. The length portion of the extension of the 116 is to provide support, i.e., the base, and also to allow the folded device 10 to be stored upright, with the legs 116 for the treadmill. It will be supported and placed vertically.
