Orthopedic computer mouse

[0001] The present invention relates generally to computer peripherals, in particular shaped mice designed to prevent diseases caused by the use of computer mice such as tendinitis, bursitis and carpal tunnel syndrome. [0002] Computer cursors are generally operated by manually operated position indicators such as mice, trackballs, touchpads, digitized tablets or similar objects. The mouse includes a housing that moves on a flat, fixed surface. The housing electrically communicates with a motion detection sensor that tracks the movement of the mouse on its bottom side, a single or multiple buttons attached to or near the anterior edge of the mouse, and a computer to which the mouse is attached. Includes circuit elements. When the mouse moves on the support surface, the cursor moves in the direction corresponding to the movement of the mouse. When the button is pressed, certain actions are performed according to the application of the software that uses the mouse. The internal components of computer mice and the operation of electrical software are well known in the past. [0003] The typical mouse, shown in U.S. Pat. No. D302.426 granted to Bradley et al., Is effectively larger in the width direction than in the height direction and is nearly lateral so that it can be used with either left or right hand. It has a symmetrical shape. Some mice have a shape specifically for the right hand. In the mouse, which is indicated by US patent number D328.597 granted to Mr. Cruzo and is a registered trademark "MouseMan" of Logitech, Inc. in Fremont, California, the finger of the right hand (hereinafter, "finger" is simply referred to as "finger") It is slightly inclined except for the index finger, middle finger, ring finger, little finger) and the approximately horizontal top surface to support the palm. Microsoft Mouse Version 2, released by Microsoft in Redmond, Washington, includes a dent on the left side that fits snugly against the bottom of the thumb and palm of the right hand. The mouse set forth in US Pat. No. 4,862.165 granted to Mr. Ghat includes a surface that supports the fingers in a substantially bent position. Some ergonomic mice, such as the registered trademark Logitech MouseMan, are also manufactured for the left hand. [0004] The most common conventional mouse is a near-horizontal main that supports the hand in a horizontal position, as illustrated in the drawing of US Pat. No. 5.157.381 granted to Mr. Chen and the drawing of the Microsoft Mouse User's Manual. Has a supportive surface. However, such prior art mice force the hands, wrists and forearms to rotate 80-90 ° from a natural and relaxed (muscle relaxed) position, in this relaxed position. It is necessary to give a certain amount of muscle strength to the hands, wrists and forearms in order to maintain the condition. For a three-button mouse, the index, middle, and ring fingers must maintain a constant tension to prevent the buttons from being overloaded and accidentally pressed down. The horizontal hand holding the conventional mouse is supported by the desk only in a small area of the palm on the little finger side, which may double the rubbing of the skin due to pressure. Overall fatigue and discomfort are less noticeable at first, but when these mice are used continuously for extended periods of time, users may experience computer mice with tendinitis, bursitis, carpal tunnel syndrome, etc. on their hands and palms. May be associated with illness, experience fatigue, discomfort, and pain associated with the use of. [0005] U.S. Pat. No. 5,576.733 discloses an ergonomic computer mouse that includes an upright primary finger that supports a surface that supports all the fingers of an upright hand in a serially stacked, vertically stacked position. .. The opposite thumb support surface is provided to support the thumb. At first glance, this arrangement is a very comfortable position. However, both the mouse disclosed in U.S. Pat. No. 5,576.733 and the other mice present have an optimal "position of action" (hereinafter also referred to as "physiological position") in which the hand, forearm, and muscle tissue rest as a whole. Will not support the hand. Maintaining the hand in a "pinching" position (such as when gripping a vertical rod) to support both the hand and the forearm in a vertically twisted position is laborious. [0006] A detailed description of the "position of action" can be found, for example, in THE HAND, 2nd Edition, Chapter 53, published by WBS aumders in 1985. It is described on pages 497 to 501, and is replaced with the description in this specification by reference to this. The action position assumes a predetermined position with respect to the position of the stationary hand. This position is primarily in the middle of the range between all movements of each joint, including the wrist, and rotation of the forearm. The forearm is in the middle position between the upward and downward palms. The wrist bends about 20 ° and bends about 10 ° (bends toward the ulna). The fingers are slightly bent at each joint, at least the index finger is bent, and the little finger is bent the most. The thumb extends forward, partially facing the palm, and the thumb joint is bent. A more detailed description of the position of action can be made with respect to the thumb. At this position, the angle between the first and second metacarpal bones is about 45 °. All of each "position of action" must be sought to combine a number of favorable conditions that are almost incompatible with each other. These positions are easy to grip, are rarely fixed, and even when finally fixed, leave room for small aptitude movements within an effective range. In the concept from the medical field, long-term working positions are acted upon to form a fixed state. It is stated in THE HAND 2nd Edition, Chapter 53, page 501 that "there is no fixed'action position'and the hand always has the action of movement". [0007] According to the above description, an object of the present invention is a physiological position or action position of the hand holding the mouse, that is, a natural, twist-free relax.<u style="single">To</u>It is to provide a shaping computer mouse having a shape to be maintained in position. [0008] Another object of the present invention is designed to prevent diseases such as tendinitis, bursa cystitis, carpal tunnel syndrome, etc., and minimizes fatigue, discomfort, and pain after long-term continuous use. Or to provide a shaping computer mouse to eliminate. [0009] Yet another object of the present invention is to provide a shaped computer mouse that is sized to fit an individual user based on the dimensions of the user's hand. [0010] Yet another object of the present invention is to provide a shaping computer mouse that is compatible with both the left and right hands. [0011] Yet another object of the present invention is to provide a "harmless" shaped computer mouse, i.e., a computer mouse that does not harm or harm the user. [0012] According to the above objectives and additional objectives described below, the present invention is a shaping computer that is movable on a supporting surface and is adapted to support a hand in a "position of action" or "physiological position". -Provide a mouse. The shape of the shaped mouse according to the present invention is developed from the shape of the human hand obtained at the position of action. This mouse is located higher than the first ridge with respect to the bottom surface, the anterior end, the posterior end, the bilateral ends, and the little finger and bottom surface located on the first ridge. It is provided with a substantially hemispherical surface for supporting the fingers of the hand at a position substantially raised with respect to the supporting surface by the index finger arranged on the raised portion. In addition, the substantially hemispherical surface is designed to support the depression of the hand, so that the hand is 45 ° with respect to the supporting surface (ie desk) and the forearm in the semi-prone position (ie between upward and downward). It is allowed to stand at the angle of. The substantially hemispherical finger support surface extends upward in the lateral direction from one of both sides. The thumb support surface is provided to support the thumb of the hand, and the mouse is placed between the thumb and the other fingers so that the thumb support surface is easily aligned with the substantially hemispherical finger support surface. It is firmly gripped. The substantially hemispherical finger-supporting surface and thumb-supporting surface work together to support the hand in a physiological position on the mouse. This form, which is an important part of the position of action, is the most characteristic property of the human hand. The work of conflicting hands is a characteristic of human beings and requires no effort. [0013] In a preferred embodiment, the surface of the substantially hemisphere joins a hypothenar depression that supports the ridge of the hypothenar of the hand and a depression of the ball that supports the ridge of the ball of the hand. There is a depression between the two ridges (hypothenar and ball). Each complementary shape is shown in the accompanying drawings referred to as "rear extension" and is shown using the ridges described in detail below. The raised forks are arranged above a substantially hemispherical surface that places the fingers of the hand in the pinching position. [0014] According to the description above, the invention is described in detail with respect to the accompanying drawings. [0015] With reference to a few figures, the shaping computer mouse of the present invention is shown. [0016] FIG. 1 shows a hand with the palm pointing downwards in the force-applied position used with the normal mouse of FIG. FIG. 3 shows a hand with the palm pointing upwards, which is opposite to the position shown in FIGS. 1 and 2. FIG. 4 shows a hand clasped by the action of the flexor muscles. FIG. 6 shows the normal mouse usage with the spread hands. [0017] Figure 7a shows the hand in the "physiological position" or "action position". "Action position" is WB It is stated in Chapter 53, pp. 497-501 of "THE HAND Second Edition" published by Saunders in 1985, and is replaced by the description herein by reference. The skeleton of the hand has lateral and longitudinal or bidirectional recesses that give the cup shape using the palm recesses as shown in FIG. 7b. Preserving the recessed portion is indispensable for the gripping action of the hand. It will be maintained in a suitable position by the substantially hemispherical surface 22. As shown in FIG. 7c, the lateral axis is positioned at an angle and extends through the metacarpophalangeal joint of the index finger and the metacarpophalangeal joint of the little finger. This axis has an angle of about 75 ° with respect to the longitudinal axis and is given approximately along the shape of the present invention. It is important that the anterior and posterior ends of the shaped mouse are aligned at the same angle on both sides, as shown in FIGS. 7d and 9. The position of action is related to the position of the hand in a stationary state and takes a fixed position. It is primarily in the middle of each range of motion of all joints, including wrist motion and forearm rotation. The forearm is in a state between when the palm is facing up and when it is facing down. The wrist bends about 20 ° to the dorsal side and about 10 ° to the ulnar side. The fingers bend slightly at each joint, the index finger does not bend the most, and the little finger bends the most. The thumbs are partially facing each other and their joints are partially bent. The position of action will be described in more detail with respect to the thumb. At this position, the angle between the first and second metacarpal bones is about 15 °. There are many ways to describe an "action position" that leads to the possible existence of one or more "action positions". THE HAND In the second edition, chapter 53, p. 494, it is stated that each and every "position of action" must ensure that a large number of favorable states, which are not necessarily comoatible, are assembled. These action positions tend to place the nodal joints in positions that are easy to grip and are rarely fixed, and ultimately, even if fixed as a result, leave room for small aptitude movements within a useful range. This is the position where the joint is placed. [0018] The shaping computer mouse 10 of the present invention can keep the hand in the "acting position" during use. Referring to FIGS. 8-16, the shaping computer mouse 10 includes a bottom surface 12, a front end 14, a rear end 16, and side surfaces 18 and 20. The front and rear ends 14 and 16 are arranged at an angle of about 75 ° with respect to the side surfaces 14 and 16, respectively, as shown in the plan overview views of FIGS. 7d and 9. The above angle of about 75 ° is given in the general shape of the present invention. The substantially hemispherical surface 22 is raised with respect to the supporting surface by the little finger placed on the first raised portion and the index finger placed on the second raised portion located higher than the first raised portion with respect to the bottom surface 12. It is provided to support the fingers of the hand at the designated position. The substantially hemispherical surface 22 joins the extension 25 for supporting the palm so that the hand rests at a 45 ° angle with respect to the support surface shown in FIG. The substantially hemispherical finger support surface 22 extends laterally upward from one 18 on both sides. The plurality of control buttons 23a, 23b, 23c are located proximal to the anterior end 14. Although shown to have three buttons, the shaping computer mouse 10 may include any number or, if desired, a single operating button. The plurality of adjacent raised ridges 23 are formed integrally with the surface 22 defined in the recess to fit the fingers. The thumb support surface 26 is provided to support the thumb of the hand, and the mouse is firmly gripped between the thumb and other fingers as shown to remain stationary without effort. The thumb support surface 26 is arranged on the opposite side of the substantially hemispherical finger surface 22. The thumb support surface 26 may have one recess defined to grip the thumb so that the thumb does not descend in the lateral edge 20 direction. The approximately hemispherical finger support surface 22 and thumb support surface 26 allow the hand to rest at a 45 ° angle with respect to the support surface in a physiologically relaxed, unbending, natural upright position (Figures 7 and 19). Collaborate with. [0019] In a preferred embodiment, the substantially hemispherical surface 22 joins the hypothenar recess 28 and the thumb 32 to support the hypothenar of the hand. The raised fork 36 is arranged above the surface of the hemisphere so as to place the fingers of the hand in the holding position. An important form of this position of action is the most characteristic property of the human hand. Hand reversal is a human characteristic and requires no effort. The entire supporting surface of the hand of the shaping computer mouse 10 may be sized to fit a particular user based on the hand dimensions measured by the hand imprint method or a similar method. In this way, deformation of the fingers and other parts of the hand is prevented. [0020] The flat bottom of the mouse comprises legs (not shown) made of conventional low friction material such as the registered trademark Teflon and a motion sensor 38 that detects mouse motion on a fixed surface or desk. ing. Although other suitable types of motion sensors can be used, in the example the motion sensor 38 is a conventional ball type device well known to those skilled in the art. The electrical cable 30 communicates electrical signals between the shaping computer mouse 10 and a computer (not shown). [0021] [0021] FIG. 17 shows an alternative embodiment in which the screen search ball 40 is provided in the thumb area. The search ball 40 contacts a conventional circuit of a type well known to those skilled in the art. This arrangement eliminates the need to physically displace the shaping computer mouse 10, and cursor operations are performed simply by operating the search ball. FIG. 18 shows another embodiment having an internet search wheel 42 in the thumb support area. It is also possible to include additional buttons located on the thumb support surface 26 to perform the desired function (action). [0022] The unfavorable conventional mouse gripped by the horizontal hands shown in FIGS. 2 and 6 is approximately parallel to the desk, and the orthopedic computer mouse is in the natural position of the approximately upright and relaxed position of FIG. It is grasped by hand. When gripped in this way, the shaping computer mouse 10 can move a long distance by moving the hand and arm together, or the shaping computer mouse 10 can move by bending the thumb and other fingers. It can be operated precisely. [0023] The upright (directional) shape of the shaping computer mouse 10 relaxes the hand<u style="single">To</u>It can be held in a natural upright position. This eliminates the substantial twisting of the hand, wrist, and forearm that was typical for traditional mouse users. The weight of the upright hand is hung over the entire lower edge, and the ball and hypothenar eminence eliminate the pressure-induced rubbing pain on the wrist that often occurs in conventional mice. Anatomically, these areas (mother, hypothenar and fingertips) are inherently supportive areas and are therefore accurately absorbed. As a result, this physiological position minimizes or eliminates fatigue, discomfort, and pain after continued long-term use and protects the user from disease. There is a depression between the two ridges (thumb and hypothenar). This ancillary and complementary shape is referred to as the "posterior extension" and is shown with the ridge of reference number 25 shown in FIGS. 8-10, 15. Ultimately, the shaping computer mouse 10 can be formed according to the user's choice, whether it is left or right. [0024] In the present invention, what are the most practical and preferred embodiments have been shown. However, it will be appreciated that those skilled in the art will make obvious modifications starting from the present invention.
