Definitions

• This invention relates to a wrist support and especially to such a wrist support which is used to support a person's hand, arm or wrist when typing with a typewriting machine and especially with a keyboard of a computer or when using the mouse of a computer.
• US Patent specification 5,050,826 tries to solve this problem with a horizontal shaft having rotatable cylindrical support pads which can be moved along the shaft.
• the apparatus has some advantages it, however, has also disadvantages.
• One of the main disadvantages is that the apparatus is quite expensive to manufacture.
• Another disadvantage is that the same is inevitably quite heavy as it is aimed to rest on a desk or table as it is.
• the support pads are also short and so the user of the pads must always relocate the pads to be in right position is respect of the wrists.
• the present invention gives a support that is also inexpensive to manufacture and always ready for use without any excessive steps to relocate any pads.
• the solution of the present invention is suitable to be used both when typing and when using of a mouse of a computer.
• Figure 1 shows one embodiment of the invention as a side view
• Figure 2 shows another embodiment of the invention as a same kind of side view as in Figure 1 in the connection of a mouse;
• Figure 3 shows a third embodiment of the invention as a same kind of side view as before.
• Figure 4 shows the movements of the solution, which is of the type shown in Figure 1 , when the hand moves resting on the same.
• Figure 1 thus shows the first embodiment of the invention where a pillow like support part 2 has been attached in a plate like part 1 .
• the keyboard 3 of a comptuter is located at least partly on the plate 1 and is at a small, adjustable distance from the pillow 2.
• the pillow 2 has been designed, according to the invention, so that its upper part 6 is separated from the lower part 7 by a narrow neck 4.
• the pillow 2 has been notched 5 on each side of the same so that the neck 4 remains between the notches 5.
• This kind of pillow construction allows the hand/wrist resting on it to be moved forward and backward (right and left in the figure) so that the contact point between the pillow and the hand changes only by "rolling" the pillow along the lower surface of the wrist. This happens so that the upper part 6 of the pillow 2 moves to certain extent and on the other hand inclines bending in the neck 4.
• Figure 2 shows another embodiment of the invention showing an analogous solution to figure 1 but the pillow has been constructed in another way.
• the mouse has been designated with the reference number 3 which mouse is moved by the hand resting on support to thereby move an arrow or another pointer on the computer's monitor.
• the flexibility of the upper part 6 of the pillow 2 is effected so that there is a hollow 8 in the pillow which is extended nearly from one side to the other whereby there remains quite narrow necks 4 on both sides of the hollow.
• the hollow 8 By making the hollow 8 suitably large the upper part 6 may move in a suitable way.
• Figure 3 shows a third alternative of the invention wherein the pillow 2 has been supported on springy members 9 on the plate like part 1 whereby the whole pillow 2 may move forward and backward following the movements of the arm resting on it.
• the members 9 may be for instance metal springs or plate like parts made of plastics having springy properties.
• Firure 4 shows how the wrist support according to one embodiment of the invention yeilds and moves following the movements of the wrist when the fingers type using the keyboard.
• the invention has been described above only schematically and for that reason the persons skilled in the art may find in the embodiments shown in the drawings many parts which may be modified. So the design or form of the pillow 2 is irrelevant in respect of the invention.
• the pillow 2 may be designed with round or angular forms or as is seen suitable.
• the upper part of the pillow may be made of material which does not induce perspiration of the hand resting on it and the lower part and especially the part 4 between the upper and the lower parts is made of suitably springy and firm material which does not loose its properties but gives, for long periods, a form which is resilient and returns flexibly to its original form.
