Claim 1
Independent Claim
147 words
A keyboard operator arm, wrist or hand support comprising: a member having a bottom adapted to rest upon a horizontal surface; said member having a top surface including a forward surface portion in a relatively low, generally horizontal plane adapted to support at least the portion of a keyboard which is proximate the keyboard operator, and a rear surface portion higher than said forward surface portion adapted to support the lower arms, wrists or hands of the keyboard operator; said top surface including at least one generally horizontal, stepped surface portion between said forward surface portion and said rear surface portion; said at least one stepped surface portion being higher than said forward surface portion and lower than said rear surface portion; and said at least one stepped surface portion being of such dimension to support the portion of a keyboard which is proximate the keyboard operator.
Claim 2
Dependent Claim
147 words
A keyboard operator arm, wrist or hand support comprising: a member having a bottom adapted to rest upon a horizontal surface; said member having a top surface including a forward surface portion in a relatively low, generally horizontal plane adapted to support at least the portion of a keyboard which is proximate the keyboard operator, and a rear surface portion higher than said forward surface portion adapted to support the lower arms, wrists or hands of the keyboard operator; said top surface including at least one generally horizontal, stepped surface portion between said forward surface portion and said rear surface portion; said at least one stepped surface portion being higher than said forward surface portion and lower than said rear surface portion; and said at least one stepped surface portion being of such dimension to support the portion of a keyboard which is proximate the keyboard operator.

Claim 5
Dependent Claim
40 words
The support as specified in claim 3 wherein: the height of each of said stepped surface portions from an adjacent lower surface portion being approximately the same as the height of the portion of the keyboard proximate the keyboard operator.
Claim 6
Dependent Claim
