Description

Device at a computer mouse
The present invention relates to an arrangement for a computer mouse formed by a body projecting upwards from a base, which body is provided with a number of manually actuated buttons or similar controls on the front part of the mouse together with a movement ball. When working with a so-called computer mouse of the conventional kind, the hand is positioned with the flat of the hand facing down towards the table, i.e. m a pronation position above the mouse.
This position of the hand and the forearm leads to (unnatural) stresses m the forearm, and these stresses have a tendency to spread upwards (m a proximal direction) towards the region of the shoulder and the neck. This working position leads to static loading of the muscles m both the arm and the shoulder region. Depending on individual factors, certain individuals are better able to cope with this loading, and others less so. Many individuals are nevertheless obliged to take frequent breaks and to perform stretchmg-like movements to counteract the pain that has arisen due to the unfavourable, imposed unnatural working position. Some individuals even need to visit a physiotherapist or to take time off work because of problems with pain m the neck-shoulders-arms.
A computer mouse previously disclosed m US, A, 5,576,733 is designed m such a way that it also permits the hand to be held m an almost vertical position, although m so doing it lacks a bottom support for the back of the hand and for the outside of the little finger. The aforementioned previously disclosed computer mouse exhibits buttons for clicking with the fingers m the conventional way. The principal object of the present invention is thus, in the first instance, to make available a computer mouse which leads, amongst other things, to reduced stresses in the musculature of those persons who use the aforementioned mouse.
The aforementioned object is achieved by means of an arrangement in accordance with the present invention, which is characterized essentially in that the aforementioned mouse body is provided with an upward-projecting part of the body formed by a central part with arched surfaces, of which one is transformed into a horizontally extending support part for the outer edge of a hand, so that the hand that comes into contact with it, in an operating position between pronation and supination, rests with the side of the little finger on a lower support part of the mouse, in that contact takes place between the inner part of the hand and one side of the mouse, in conjunction with which actuating buttons are situated on the front, essentially upright side of the mouse, in that the aforementioned upward-projecting part is fixed in relation to the aforementioned supporting part, and in that an actuating button for clicking is situated on the top side of the mouse in the area directly in line with the inside of the hand, so that clicking with the aforementioned button can be executed by performing a pronation movement with the whole hand, i.e. the flat of the hand is rotated towards the base from an upright rest position.
The invention is based on the principle that, if the flat of the hand is placed against the desk in a "pronated position", this leads to stresses in the musculature. The same is true if the back of the hand is placed against the desk in a "supinated position" (although probably to a rather smaller extent) . If, however, the hand is placed on the desk in a position half-way between pronation and supination, the least possible stresses will occur in the musculature of the arm and shoulders. The present ergonomic computer mouse is designed so that the side of the little finger rests on the mouse, and sufficient contact occurs between the hand and the computer mouse due to the weight of the hand, so that the mouse can be moved over the desk without the need to grip the top of the mouse in order to cause the computer mouse to move. The computer mouse provides support from the wrist region all the way to the little finger. The mouse is constructed to some extent in the wrist region to correspond to the anatomical conditions. The height of the computer mouse is adapted to provide support for the flat of the hand. The ergonomic computer mouse also represents a novel approach with regard to the click function. On the one hand, the possibility is provided for clicking with the index finger on the front part of the mouse. A click function is also provided in the rear upper part, so that clicking can be executed by performing a pronation movement with the whole of the hand. (Pronation movement: i.e. the flat of the hand is rotated towards the base from the normal position) . The ergonomic computer mouse in accordance with the invention can be summarized as representing a novel approach to working with a computer mouse. A more relaxed working position is obtained by changing the working position and the clicking function as described above. The muscles that are used and placed under load are larger and more capable of resisting loading than the muscles used with a conventionally designed computer mouse. Furthermore, a smaller number of muscles in the arm is activated by the ergonomic computer mouse in accordance with the invention, which leads to reduced stresses in the arm and shoulder. Fewer computer users will probably now be affected by injuries at work. There will be a lower frequency of absences from work due to illness, a reduction in the consumption of pain-killing medicines (analgesics), and employees will no longer have to interrupt their work as often to perform stretching movements .
The invention is described below as a preferred illustrative embodiment, m conjunction with which reference is made to the drawings, in which:
Fig. 1 shows a perspective view of a mouse m accordance with the invention, viewed at an angle from below and from the front;
Fig. 2 shows the mouse viewed at an angle from the front and from above;
Fig. 3 shows the mouse viewed at an angle from behind;
Fig. 4 illustrates schematically how a hand is positioned when using a mouse m accordance with the invention, viewed in a direction away from the inside of the hand; and
Fig. 5 shows the mouse with a hand viewed from its outside .
An arrangement 1 for a computer mouse 2, which is formed by a body 4 projecting upwards from a base 3, for example a mouse mat or some other such device, which body is provided with a number of manually actuated buttons 5, 6 or a similar means of control on the front part 7 of the mouse and a movement ball 8 on its under surface 9, has the aforementioned mouse body 4 so arranged m accordance with the present invention as to comprise an upward-projecting mouse body part 10, which is designed and arranged m a special way. More specifically, the upward-projecting body part 10 is designed so that the hand 11 that is placed on it, with its inside 11A m an operating position I between pronation and supination, rests with the side 11B of the little finger on a support part 12 of the mouse 2, so that contact takes place between the inner part 11A of the hand and one side 2A of the mouse 2. Actuating buttons 5, 6 are situated m this case on the front, essentially upright side 2B of the mouse, and the aforementioned upward-projecting part 10 is arranged so that it is fixed m relation to the aforementioned lower support part 12.
The upward-projecting body part 10 of the mouse is formed m this case by a central part provided with arched surfaces 13, of which one is transformed into a horizontally extending support part 14 for the outer edge 11B of a hand 11; see Fig. 5. The aforementioned central part 10 in this case exhibits a height H that is less than the width B of an adult person's hand. The height H is selected so that the inner part 15A of the thumb 15 is so arranged as to make contact with a central part 16 of the body part 10, with the index finger 17 extending along the upper part 16 of the central part m a forward direction towards the front, upright side 2B of the mouse.
A wrist support 18 is situated on the rear projecting side part 14A of the mouse, m the form of an extended raised part. An actuating button 19, which is so arranged as to be applied for clicking with so-called double clicks, is situated on the top side 10 of the mouse m the area directly m line with the inside 11A of the hand and the inner part 15A of the thumb, so that clicking with the aforementioned button 19 can be executed simply by performing a pronation movement with the whole hand 11, i.e. the flat of the hand 11A is caused to rotate towards the base 3 and m towards the mouse 2 from an upright rest position I .
Pairs of actuating buttons 5, 6 intended for clicking are also situated m line on the front upward- projecting side 2B of the mouse, with one of the buttons, the so-called selector button-primary button 5, positioned above the other button 6, the so-called function button-secondary button.
A horizontal finger support part 20 projecting m a forward direction is situated on the front side 2B of the mouse on its lower part 21. The invention should by now have been appreciated from what is described above and illustrated in the drawings, although it is not restricted to the foregoing and may be varied within the scope of the Patent Claims without departing from the idea of invention.
