Abstract
Abstract An improved wrist rest (10) is disclosed for reducing repetitive motion strain injuries on the wrists of a typist or computer keyboard operator. Wrist rest (10) is located in front of and parallel to a keyboard (60) or other typing device such that the wrist or wrists (15) of a user is (are) positioned directly over the wrist rest (10) while typing. Wrist rest (10) consists of an elastic envelope (40) filled with a gelatinous material (50) which provides cushioned support for a user's wrists while maintaining the wrist or wrists in a relatively straight position. In some embodiments the gelatinous material (50) can be chilled or heated to provide a source of cold or heat for a period of time. The gelatinous material (40) can be held in place by a base support means (20). In some embodiments wrist rest (10) can be grasped with both hands and squeezed, propelling the gelatinous material within the elastic envelope, thereby functioning as an exercise means for the hands and fingers of the hands.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
75 words
A wrist rest and exercise apparatus, for a user's wrists, hands, and fingers comprising, in combination: a thermally conductive gelatinous resilient means for providing a cushion for a user's wrist, said gelatinous resilient means having a generally deformable surface for providing a contact area shaped to said user's wrist; enveloping means for containing and protecting said gelatinous resilient means; covering means disposed about said gelatinous resilient means on which said user's wrists may be disposed.
Claim 2
Dependent Claim
75 words
A wrist rest and exercise apparatus, for a user's wrists, hands, and fingers comprising, in combination: a thermally conductive gelatinous resilient means for providing a cushion for a user's wrist, said gelatinous resilient means having a generally deformable surface for providing a contact area shaped to said user's wrist; enveloping means for containing and protecting said gelatinous resilient means; covering means disposed about said gelatinous resilient means on which said user's wrists may be disposed.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 wherein said thermally conductive gelatinous resilient means may be chilled to less than zero degrees Centigrade.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 wherein said thermally conductive gelatinous resilient means may be heated from about 32 to about 50 degrees Centigrade.
Claim 5
Dependent Claim
18 words
The apparatus of claim 3 wherein said thermally conductive gelatinous resilient means may be heated using microwave radiation.
Claim 6
Dependent Claim
16 words
The apparatus of claim 1 in which said enveloping means is comprised of an elastic envelope.
Claim 7
Dependent Claim
14 words
The apparatus of claim 1 in which said covering means comprises a removable fabric.
Claim 8
Dependent Claim
31 words
The apparatus of claim 1 in which said covering means contains frictional means embedded within, and protruding throughout, a lower surface of said covering means in communication with a support surface.
Claim 9
Dependent Claim
33 words
The apparatus of claim 1 in which said covering means contains massaging means embedded within, and protruding throughout, an upper surface of said covering means in communication with said wrist of said user.
Claim 10
Dependent Claim
24 words
The apparatus of claim 1 wherein contained within said enveloping means are internal support means for providing support and shape to said wrist rest.
Claim 11
Dependent Claim
11 words
The apparatus of claim 1 further comprising a base support means.
Claim 12
Dependent Claim
18 words
The apparatus of claim 10 wherein said base support means, longitudinally, concavely and rigidly seats said wrist rest.
Claim 13
Dependent Claim
23 words
The apparatus of claim 10 wherein said base support means consists of flexible material such that it may be shaped by said user.
Claim 14
Dependent Claim
22 words
The apparatus of claim 10 wherein said base support means includes means for adhering said wrist rest to said base support means.
Claim 15
Independent Claim
139 words
A method for relieving repetitive motion stress on the wrists of a user while using a device on a work station wherein using said device requires repetitive motion of the fingers and hands, said device including a keyboard and a mouse of a computer, said method including the steps: positioning on a surface of said work station, and positioned parallel to a leading edge of said keyboard, a relief means with a length substantially equal to said leading edge, a height and a width, said relief means including a deformable thermally conductive gelatinous material having a generally cylindrical shape, a means for containing said gelatinous material, and a fabric covering wrapped around said means for containing said gelatinous material and wherein said height has a value selected to position said wrists on said relief means while using said device.
Claim 16
Independent Claim
139 words
A method for relieving repetitive motion stress on the wrists of a user while using a device on a work station wherein using said device requires repetitive motion of the fingers and hands, said device including a keyboard and a mouse of a computer, said method including the steps: positioning on a surface of said work station, and positioned parallel to a leading edge of said keyboard, a relief means with a length substantially equal to said leading edge, a height and a width, said relief means including a deformable thermally conductive gelatinous material having a generally cylindrical shape, a means for containing said gelatinous material, and a fabric covering wrapped around said means for containing said gelatinous material and wherein said height has a value selected to position said wrists on said relief means while using said device.
Claim 17
Dependent Claim
22 words
The method of claim 14 wherein said thermally conductive gelatinous material may be chilled below the freezing point of the gelatinous material.
Claim 18
Dependent Claim
22 words
The method of claim 14 wherein said thermally conductive gelatinous material may be heated from about 32 to about 50 degrees Centigrade.
Claim 19
Dependent Claim
17 words
The method of claim 14 wherein said thermally conductive gelatinous material may be heated using microwave radiation.
Claim 20
Dependent Claim
27 words
The method of claim 14 wherein said method further includes manipulation of relief means by a user for exercising the hand and the fingers of the hand.
Claim 21
Dependent Claim
22 words
The method of claim 14 wherein said relief means includes a means for providing internal support and shape for said wrist rest.
