Abstract
When using a computer keyboard, or a computer cursor display control device known as a mouse, the shoulder, elbow, and wrist can become tense and uncomfortable as a result of strained muscle.
To prevent such cases, a tool generally known as a wrist rest is used to support the hand Different wrist rests are used for keyboards and mice. In this invention, unlike prior art wrist rests which all have a flat base, a shorter member with a convex base and a top surface covered with suitable material such as neoprene etc., and having straight sides is used. Two separate devices are preferred for supporting the two hands. One device can be used as a wrist support for using a mouse. If desired, two or more of this device can be connected together to form a longer device.
The convex base enables the flat top surface of the device to conform automatically, by tilting backward or forward as the hands work, to the changing angle of the hand. The tilting action can be steadied by placing the side of the device against the side of the keyboard or mouse pad if desired. Unlike the prior art desk pads, the mobile wrist support device can be used with keyboards and mice of any size and shape. Its shorter length allows it to be carried easily in laptop computer cases.

Description
Specification This invention relates to a tool for supporting the hand, wrist, forearms and elbow to prevent or reduce muscle strain while working with keyboards and computer mice. Prior art wrist supports for using keyboards consist of a pad positioned horizontaUy, in normally fixed relation above and along the front edge of the keyboard, usually connected to a tray on which the keyboard rests.
Prior art wrist support for using computer mice consists of a pad as the surface on which to move the mouse in combination with a pedestal on which to rest the wrist. Other prior art wrist supports for computer mice include Canadian patent number 2105033. Tools of this type are inefficient and ineffective because the pads are designed for either the mouse or the keyboard. They usually are fixed in one position and are fitted exactly to the length, height and shape of a particular type of keyboards or mouse pads. Thus, the pad used for the keyboard cannot be used for the mouse thus ~ pads are required for the keyboard and mouse. Further, they are ineffective for forearm and elbow support because they usually are too narrow, not long enough to support the two elbows which are wider apart than the hands while typing, or in a fixed position thus not convenient to be moved under the forearm or elbow. Some pads designed to support the forea~ns are unnecessary wide thus take up too much desk space. Still further, the height and angle of the wrist support in relation to the keyboard or mouse pad require a complex mech~ni~m and manual adjll~t~n~nt in order to m~;nt~in its effectiveness. Still further, it is not convenient to transport the previous wIist supports because of their large size.
I have found that the disadvantages of the previous wrist supports may be overcome by using two separate support pads for the two hands and by having the convex part of the semicircle member as the base of the device, the flat part of the semicircle member as the top surface and shorten the side length of the support pads.
The shorter side length of my invention is aim to fit the hand instead of the keyboard or mouse pad; thus it can be placed anywhere on the desk and under either the wrist, forearm or elbow.
Further, the hand fitting feature allows the device to be used alternately for a keyboard or a mouse.
Therefore this will avoid the inefficiency of purchasing different size pads to ft di~clc~l size keyboards and mice.
The convex base of my device allows the top surface of the device to incline, automatically, backward or forward to conform with the angle of the hands while wolkillg with different keyboards or mice, or when chqt ~in~ the hands' position to avoid pres~u,e points. This feature and the mobility of the device enable it to m-q~ tqin its effectiveness regardless of difference in height, angle and length of different keyboards and mouse pads. Thus no complex mechal~-.l and manual adjustment are required to mq;~fqill its effectiveness. If desired, the tilting action can be ~te~1ied by placing the side of the device against the side of the keyboard or mouse pad.
Further, the device is small thus it is convenient to carry from place to place in a laptop computer case.
Still further, if a longer device is desired, two or more of my device can be connected together to form a longer device. This can be achieved by placing a sturdy inner member along and inside the center of the device, having its two ends exposed and having means of fastening another wrist support device. To connect the two devices, simply insert the protruding dowel at one end of the inner member into the cavity at the end of the inner ...~mbel on the next device.
It is among the objects of my invention to provide a device that can be used to support the hand, wrist, forearm and elbow as desired when used with keyboards and mice of any size and shape.
It is a further object of my invention to provide a device that conforms to the angle of the hand, forearm etc. automatically while work1ng without requiring a complex mech~ni~m and manual ~djll~tn~ent.
It is a further object of my invention to provide wrist supports that are easier to carry from place to place in a laptop COnl~ il case.
These objects and adv~nt~g~s, as well as other objects and advantages, can be achieved by the mobile support device illustrated in the dld~lll~ in which Figure 1 is a top plan view of the mobile support device, Figure 2 is a front view with a pad cushion ~ ed to the top surface, Figure 3 is a side view, Figure 4 is a view in p~ pe~ Je with a pad cushion shown above the top surface. Figure 5 shows how one device can be connected to another. Figure 6 is a view in perspective of the device without the pad cushion and the sturdy inner n~nlber in the middle of the device.
Referring to the ~a~il~ in detail, my mobile support device is co~ lng of an outer semicircle member 1 having straight sides 2. The semicircle member has a preferred radius of four cm and the sides have a preferred length of seventeen cm. The convex side 3 of the semicircle member is the base, the flat side 4 is the top surface to which a pad cushion 9 is attached. Along and inside the center of the semicircle member is a sturdy member S having its two square ends with a convex bottom exposed 6 and having means of fa~tçning 7 another wrist support device. The two ends 6 of the inner member being larger in size then the middle section 8 of the inner member which is square shaped.
The outer nlember can be made from material such as polyurethane, vinyl, rubber, plastic, foam and the like or a combination thereof. The top surface can be covered with va1ious m~t~n~l~ such as soothing gel, neoprene, Iycra and the like to make it comfortable for users to rest the hand.
Also, the top surface can also be formed, shaped or moulded to fit the palm and wrist to increase the comfort level. The plefell~d material for making the inner member is sturdy plastic.
The use of my invention is to support the hands, wrist1 forearm and elbow while typing on keyboards or using a mouse. To use this invention, one device is placed under each of the right and left hand, wrist, elbow, or forearm where it feels comfortable. You can change the position of the device under and along the hand, wrist, elbow, and forearm as desired to avoid p~es~ul'e points.
To use the mouse, only one device is required.
I have shown one preferred embodiment of a mobile support device, of course, any top surface and any minor change in the shape may be used. The ful~goillg is intended merely to be illustrative of one embodiment of my invention, for many changes may be made in the construction, selection, and allangement of the parts, all within the scope of the appended claims without departing from the spirit of the invention.
