Wrist rest assembly
First Claim
1. A wrist rest for use in supporting a person'"'"'s wrist while operating a computer keyboard or mouse, said wrist rest comprising:
- a base having a top surface and a bottom surface, said bottom surface adapted to reduce movement of the wrist rest in use;
an elastomeric gel layer supported by the top surface of said base, said elastomeric gel layer having;
a) a top surface and a bottom surface;
b) an elastomeric polymeric network with a substantial portion of liquid entrapped within the polymeric network;
c) stability, such that the elastomeric gel layer has substantially invariant physical properties over time;
d) flexibility and compressibility in the general range of flexibilities and compressibilities of elastomeric gels made by mixing from about 4 to about 10 parts of U.S.P. Nujol brand mineral oil with one part Kraton 107 styrene-isoprene-styrene and heating the mixture to approximately 149 degrees C while agitating vigorously until the styrene-isoprene-styrene appears visually dissolved, wherein the flexibility is such that the elastomeric gel layer flexes in a lateral direction so that the top surface of the elastomeric gel layer moves relative to the bottom surface of the elastomeric gel layer in a plane generally parallel to the top surface of the base and wherein the compressibility is such that the elastomeric gel layer compresses in a direction generally perpendicular to the bottom surface of the elastomeric gel layer, such that the elastomeric gel layer conforms to a user'"'"'s wrist; and
e) a sufficient thickness of the elastomeric gel layer between the top and bottom surfaces thereof to afford significant movement of the top surface of the elastomeric gel layer in direction generally parallel to the bottom surface of the gel layer.

Abstract
A wrist rest assembly for use along the front edge of a device to be operated by a person'"'"'s hands or fingers, such as in front of a computer keyboard, including an elongate base on which is supported an elongate pad comprising a layer of gel within the covering. The pad has sufficient thickness between its top and bottom surfaces and width between its edges to afford supporting a users wrists on the top surface with a portion of the layer of gel beneath and conforming to the supported wrists and to afford significant motion of the top surface of the pad with the supported wrists relative to the bottom surface in a plane generally parallel to the upper surface of the base. The base has a top portion supporting the pad, a bottom portion adapted to be supported on a horizontal surface; and structure that allows the top portion to be supported on the bottom portion with the top surface of the pad at a predetermined one of several different distances above that horizontal surface.
