Abstract

An elongated resilient pad is removably mounted in an elongated structure and is removably retained on the bottom surface of the structure. A portion for underlying the keyboard extends from the bottom surface along one edge of the structure and in the same plane as the bottom surface. The resilient pad is covered with a soft, absorbent, washable material and the cover encases a washable, foam material. The resilient pad may be a water-filled pouch which is also covered with a soft, absorbent, washable material.

Claims

1. A wrist support arrangement for use with a stand-alone keyboard, comprising:

an elongated resilient pad;

an elongated structure, having a bottom surface, for removably mounting said pad, said structure including pad retaining means for removably retaining said pad on said bottom surface of said structure, said retaining means being spaced from said bottom surface and overlying a portion of said resilient pad when said resilient pad is mounted in said elongated structure, wherein unaided movement of said resilient pad away from said bottom surface is prevented by said retaining means; and

means for maintaining said elongated structure in fixed relationship with said keyboard.

2. An arrangement as defined in claim 1 wherein said elongated structure comprises a rectangular box-like structure having a bottom wall, two end walls and two side walls, said end walls and side walls all being of the same height, an open top defined by the top edges of said end walls and said side walls;

said retaining means comprising a first member extending from one of said side walls to the other one of said side walls and disposed at one end of said boxlike structure and a second member extending from said one side wall to said other one of said side walls at the other end of said structure.

3. An arrangement as defined in claim 2 wherein said resilient pad includes a cover, said cover comprising a soft, absorbent, washable material.

4. An arrangement as defined in claim 3 wherein said material comprises a cotton cloth material.

5. An arrangement as defined in claim 1 wherein said resilient pad comprises a water-filled pouch.

6. An arrangement as defined in claim 5 wherein said water-filled pouch has a cover, said cover comprising a first, inner, water-impermeable layer, and a second, outer, layer covering said first layer, said second layer being made of a soft, absorbent, washable material.

7. An arrangement as defined in claim 6 wherein said material of said second layer is a cotton cloth material.

8. An arrangement as defined in claim 3 wherein said means for maintaining comprises a portion for underlying said keyboard, said portion extending from said bottom surface of said elongated structure along an edge thereof and in the same plane as said bottom surface.

9. An arrangement as defined in claim 1 wherein said resilient pad comprises a flocked foam material.

10. An arrangement as defined in claim 1 and further including a static discharge path, said path comprising a conductive thread knit or woven into said material, one end of said thread being connected to a primary power ground.

11. An arrangement as defined in claim 3 wherein said material comprises a knit material.

12. An arrangement as defined in claim 3 wherein said material comprises a woven material.

24. An arrangement as defined in claim 11 or 13 wherein said resilient pad comprises a washable foam material encased in said cover.

13. A wrist support arrangement for use with a stand-alone keyboard, comprising:

an elongated resilient pad;

an elongated structure, having a bottom surface, for removably mounting said pad, said structure including pad retaining means for removably retaining said pad on said bottom surface of said structure; and

means for maintaining said elongated structure in fixed relationship with said keyboard;

said means for maintaining comprising a portion for underlying said keyboard;

said portion extending from said bottom surface of said elongated structure along an edge thereof and in the same plane as said bottom surface.

14. An arrangement as defined in claim 13 wherein said resilient pad includes a cover, said cover comprising a soft, absorbent, washable material.

15. An arrangement as defined in claim 14 wherein said material comprises a cotton cloth material.

16. An arrangement as defined in claim 15 wherein said material comprises a knit material.

17. An arrangement as defined in claim 16 wherein said material comprises a woven material.

18. An arrangement as defined in any one of claims 15, 16, or 17 wherein said resilient pad comprises a washable foam material encased in said cover.

19. An arrangement as defined in claim 13 wherein said resilient pad comprises a water-filled pouch.

20. An arrangement as defined in claim 19 wherein said water-filled pouch has a cover, said cover comprising a first, inner, water-impermeable layer, and a second, outer, layer covering said first layer, said second layer being made of a soft, absorbent, washable material.

21. An arrangement as defined in claim 20 wherein said material of said second layer is a cotton cloth material.

22. An arrangement as defined in claim 13 wherein said resilient pad comprises a flocked foam material.

23. An arrangement as defined in claim 13 and further including a static discharge path, said path comprising a conductive thread knit or woven into said material, one end of said thread being connected to a primary power ground.
