Description

Structure of input button of anti-Carpal Tunnel Syndrome mouse}

The present invention relates to an input button structure of a mouse for preventing carpal tunnel syndrome, and more particularly, to an input button structure of a mouse for protecting the wrist when the input button is clicked and reducing fatigue of the most used and important detection and stopping.

A mouse is a kind of computer peripheral widely used as an input means. It is a ball installed on the bottom surface of the lower case, a contact shaft which is installed in contact with the ball and rotates synchronously as the ball rotates, and a plurality of uniform grooves on the outer peripheral surface. Is formed and provided at one end of the rotating shaft, the optical sensor for generating a signal according to the rotation direction, the rotation angle of the slit, the microcomputer for detecting the coordinate value according to the signal generated from the optical sensor, the lower case It consists of a tact switch installed in the transverse direction at the front end, and two input buttons (right and left but of course not universal) having respective contact protrusions to operate each tact switch. have.

Therefore, the conventional mouse 100 moves by hand to adjust the position of the cursor, and inputs a coordinate value by pressing an input button by using the index finger and the middle finger.

However, in the conventional mouse, as shown in FIG. 5, since the inclination angle of the input button maintains the inclination which is almost horizontal when the inclination angle is based on the horizontal plane, as shown in FIG. The input button is pressed at, which moves the entire index finger and middle finger to apply force to the input button, which causes the transfer of force when clicked through the entire tendon of the finger, causing diseases such as hay fever and carpal tunnel syndrome. Is how to use a large finger.

For reference, the structure of the finger (physical phalanx) consists of 3 nodes (ignorance 2 nodes), respectively, from the end of the node to the distal phalanges, middle phalanges, and proximal phalanges, with the nodes between the distal phalanges and the proximal phalanges. It is composed of limb joints. In addition, hands and wrists are composed of flexors and extensors, which can bend or extend the fingers and wrists. In particular, when looking at the structure of the wrists, the base of the carpal bone forms a concave arch. Covering the carpal tunnel (tunnel) and through the narrow carpal tunnel through the jangmujijigeun tendon to the thumb, shiji, middle finger, rehabilitation, cheonjiguleuneun tendon and wickedjiguneuneun going to the base, the median nerve pass each to perform the flexor movement of the fingers. When repeated mechanical stimulation is applied to the carpal tunnel, which is filled with various structures as described above, edema is generated, which causes pressure on the median nerve, causing symptoms such as numbness, pain, numbness, and muscular atrophy of the hand and wrist. This is called carpal tunnel syndrome.

Therefore, as the utilization of the mouse gradually increases, the ligaments and tendons of the index finger and middle finger can be concentrated and used excessively, which causes carpal tunnel syndrome, which leads to numbness, pain, paralysis, muscle atrophy, and even unusability of the hand. Will be exposed to. Therefore, in order to prevent computer users such as internet users and game workers from diseases such as hay salt and carpal tunnel syndrome, the mouse manufactured by considering only aesthetic and convenience-oriented engineering until now, human body design Considering the surface, the mouse is more desperately needed than ever.

Therefore, the present invention is to form a hill at the distal joint to block the transmission of the force when clicking the entire finger tendon by limiting the force at the click of the button to the distal phalangeal region by the movement of the index finger and middle finger By reducing or dispersing the force as much as possible to transmit to the carpal canal can prevent wrist diseases such as carpal tunnel syndrome.

In addition, the pressing portion corresponding to each finger is formed on the input button so that the fatigue concentrated on one or two fingers can be distributed to all the fingers, and the pressing portion is able to use all five fingers by varying the height by the step. By increasing the height of the pressing part corresponding to less important fingers (ie, thumb, ring finger, and possession) instead of using it frequently, the frequency of use can be increased, and thus the fingers can be used in a balanced manner. Is a significant improvement.

In addition, in order to secure the efficiency of the instantaneous force, and to prevent the loss of force due to the sliding by forming a ring-like protrusions in the pressing portion of the input button is configured so that the fingers do not slip.

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of the present invention, the present invention is conventional in inputting coordinate values by pressing the input button (10, 20) with a finger in the known input button (10, 20) used in the conventional mouse (100) It was not possible to press the finger down from the top like a way to bend the switching so that switching can be made, for this purpose, the hills protruding along the input button (10, 20) on the top of the input button (10, 20) 50) but the hill 50 is formed at a position corresponding to the distal joint, so that the force to click is not transmitted to the carpal canal but limited to only the distal phalangeal region, thereby reducing or dispersing the movement and power of the finger as much as possible. To prevent wrist diseases such as carpal tunnel syndrome.

In addition, the pressing portions (11, 12, 21, 22, 23) corresponding to each finger are formed on the input buttons (10, 20), the pressing portions (11, 12, 21, 22, 23) is stepped (30) By changing the height by the five fingers can be used all, especially by increasing the height of the pressing portion (11, 22, 23) corresponding to less important fingers (ie thumb, ring finger, and possession) without using relatively often By increasing the frequency of use, it was possible to balance the fingers.

That is, in order to be able to press the input buttons (10, 20) using all five fingers, the left input button 10 is formed with a thumb pressing portion 11 and the index pressing portion 12, the right input button 20 ), The stop pressing portion 21, the ring finger pressing portion 22, the holding pressing portion 23 is formed, the input button (10, 20) has a step 30, such as a step for each pressing portion to raise the height The fingers, fingers, and fingertips, which are fingers that are not frequently used, are slightly higher in order than the middle finger or fingertips, so that the frequency of use of the thumb, ring finger, and fingertips is increased. It is to reduce the fatigue and burden on the two fingers.

In addition, the surface of the pressing portion (11, 12, 21, 22, 23) bulge (40) formed by protruding minute projections of the ring shape or fingerprint, which is a means for preventing the loss of force by preventing the sliding of the moment when the button is pressed ) Was formed.

As described above, the mouse according to the present invention has five fingers in contact with each input button (10, 20), but the low frequency of use of the finger is different from the height so that the contact is easy to press the force of the finger applied when clicking the input button Dispersion is spread across all fingers, which significantly reduces the strain on the wrist.

Like this, click of input button is not always index or stop but thumb and index or stop and ring finger or possession can be clicked. The formed contact protrusion presses the tact switches 10a and 20a to generate an electrical signal for inputting a coordinate value, thereby driving the desired mouse.

The present invention is to form a hill at the top of the input button by using the mouse to push the input button as usual, instead of pressing from the top to the bottom of the finger so that switching is made by limiting the force to the distal phalanx to the carpal tunnel. It also minimizes the force transmitted, and integrates the click buttons horizontally and heights so that all five fingers can be used, and increases the frequency of use of less important fingers rather than relatively frequently. By forming a ridge to minimize the force lost by the configuration, it is possible to minimize the frequency of use of the most commonly used index finger and middle finger, and to use the fingers in a balanced manner to prevent carpal tunnel syndrome. Having All.
