Abstract

The invention relates to a device for supporting the wrist of a hand guiding a computer mouse. The device also ensures that the user's hand remains comfortable during every action, whilst guaranteeing freedom of movement across the top of the mouse. Figure 1 illustrates an inventive embodiment of the wrist support for use with the right hand. The invention overcomes the disadvantages of other models and meets the requirements of a wrist support for working with a computer mouse in an advantageous way. The design consists of a foam block (1) with an advantageous density volume. One of the four horizontal faces of the block is oriented towards the user's arm and one face is oriented towards the mouse. An asymmetric, wedge-shaped recess is created in the level top surface (8) of the block, said recess running from the arm end to the mouse end, that is from B to B', at an angle of 12 degrees to the axis AA'.

Description

WRIST LOPS FOR WORKING WITH THE COMPUTER MOUSE

description

The invention is based at work with the computer mouse, the joint of them leading hand and holds the hand in all phases of the work easily and at the same time freely movable at the height of the top of the computer mouse.

To control the input to display units of computers all computer configurations with its own hand are practically - positioning device (computer mouse) as standard.

With the computer mouse both a number of general control operations and special commands in the applications run on the screens of computer configurations. Therefore, as many times as the computer mouse is used.

This performed with the computer mouse operations on the screen lead to increased stress on the joint of the computer mouse guiding hand. By prolonged labor, particularly for work in professional work, it can therefore be used for "wrist - stress - syndrome" come.

To reduce the resulting in use of the computer mouse strain of the wrist and hand muscles leading the forearm are the following requirements to fulfill that objects of the invention:

Requirement 1: With each movement of the computer mouse, the entire guiding hand including her wrist up to the arm-side approach of the lower arm must be free to move.

Requirement 2: In the resting phase the guiding hand must be able to support up to the hand-side edge of her wrist. This support must be on the level of the upper edge of the computer mouse.

Requirement 3: The embedding of the wrist needs in relation to the arm in an anatomically appropriate angle to the outside, by the right hand to the right, with the left hand to the left, take place.

Requirement 4: Only the immediately adjacent to the wrist zone (5 - 3 cm) must be the underside of the forearm permanently elastically supported. This support must be significantly higher than the support of the hand-side edge of the wrist.

Requirement 5: The unsupported part of the forearm must remain free to move both the individual coordination with the guiding hand as well as the change in posture. Requirement 6: Joint support must each be mirror-symmetrical different for the use of the right and left hand.

Requirement 7: The device must be flexible to different formations of the hand, wrist and forearm can customize and inviting in its form directly to the functionally correct use.

Support item to work with the computer mouse are a number of solutions. To view the current state of the art.

DP 44 93 807 shows in no. 10 of FIG. 3 is a rigid support which makes the functional support of the wrist possible, but does not include the arm-side region of the forearm. Likewise, when moving the computer mouse the wrist can not be relieved. US 5,165,630 embeds the guiding hand on a flat, stapled to the back of the computer mouse foam - surface. However, the support of the wrist is required only in the resting phase at this point; on movement of the hand lacks the arm-side support behind the wrist. By attachment of the post described therein both the guiding hand and the computer mouse are hindered in their movement. US 5,340,067 shows in no. 18 of FIG. 4, the correct functional support of the wrist and its armseitig adjacent region of the forearm, but additionally supports disadvantageously palm and thumb of the guiding hand and thus makes the movement of a leading hand and computer mouse impossible. US 5,472,161 can be attached for use with the computer mouse on the arm-side zone behind the wrist, but does not support the hand in the resting phase and, thanks to their hard material not comfortable embedding. US 5,335,888 embeds wrist and the entire forearm adversely in a rail-like foam structure one; This construction prevents the free movement of the forearm and thus leads in addition to the load of the wrist, in addition to the stress by leading arm and shoulder.

In Fig.1 a erflndungsgemässe embodiment of the joint support for use is shown with the right hand, which overcomes the disadvantages of the solutions described and combines the requirements of a hinge support for the work with the computer mouse outset in an advantageous manner and thus the total of assigned tasks Fulfills. The execution consists of a block 1 made of foam (hereinafter referred to as "block") with an advantageous space density of 30 to 10 kg / m.3. The maximum length of this block is 160 mm, the maximum breadth of 120 mm and its maximum height 50 mm. of the 4 horizontal sides of the block, one each side facing the arm, and one of the computer mouse. In the flat top face 8 of the block an asymmetrical, wedge-shaped recess with its leading line 2 (hereinafter referred to as "well") is attached. This recess proceeds at an angle of 2 degrees to the axis AA 'of the arm - side to the computer mouse - side, ie, from B to B' and has a length of 57 mm. The lowest point of this recess 3 lies on the side facing the computer mouse 22 mm above the support surface of the block and thus reaches the height of the upper edge of commercially available computer mice. The recess in the block, through line 2, is at its (of the arm side as seen) left-hand side of an area formed by line 2 and the top of the block cutting edge 4 soft at an angle of 17 degrees to the axis AA 'of the arm - side to the computer mouse - page runs. The third edge of the left side of the recess is formed by connecting the end points of the lines 2 and 4 to the vertical, facing the side computer mouse. The right side of the recess consists of a wider trapezoidal and a smaller triangular area. The larger trapezoidal surface is formed by 2 and the top of the block which the cutting edge 5 at an angle of 51 degrees to the axis AA 'of the arm - extending side - side to the computer mouse. The third edge of the larger trapezoidal surface of the right side of the recess formed by the bottom of the smaller triangular area 6, which extends parallel to the axis AA 'and has a length of 20 mm. The fourth side is formed by connecting the end points of the lines 2 and 6 on the vertical, the computer mouse facing side. The smaller triangular surface of the right side of the recess is formed from line 6 and that the top of the block cutting edge 7 in an angle of 35 degrees to the axis AA 'of the arm - extending side of the block - side to the computer mouse. The third edge of the smaller triangular area is formed by connecting the end points of the lines 6 and 7 on the vertical faces of the computer mouse of the block. Between the edge 5 and the arm-side edge of the block is the support surface 8 for the arm-side region of the forearm.

The effectiveness of the inventive joint support was tested with 5 trained in the use of computer mouse people. These individuals have a CAD - created system the floor plan of a house, including dimensioning. This work lasted 1 hour each, and was conducted in separate sessions once each with and without the inventive joint support. It was found that without the use of the inventive joint support which borders on the wrist region of the forearm in 4 of the 5 persons occurred tenderness, swelling and dull pain. When applying the inventive joint support these phenomena occurred only at a person and there in significantly geringerm extent.
