Abstract
Abstract A wrist and forearm support apparatus for use at a desk or table to prevent overuse of the forearm muscles and to prevent nerve compression at the wrist of individuals performing typing or other keying activities. The wrist and forearm support apparatus comprises a cushioned wrist support member having a pair of cushioned armrest members pivotably connected thereto for adjustment to angular positions providing optimal support for an individual user, and a clamping mechanism disposed at forward ends of the armrest support members for attaching the wrist support member and the armrest as a unitary structure to an edge of the table.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
192 words
An apparatus for clamping to a table to support both wrists and forearms of a person while working at the table comprising: (a) a cushioned wrist support member; (b) a pair of cushioned armrest members pivotally connected to said cushioned wrist support member to adjust the angle between said armrest members and said wrist support member; and (c) means at forward ends of said armrest members including a generally planar, upwardly facing surface for attaching said wrist support member and said armrest members to an edge of the table with said wrist support member adapted to be fixed in a horizontal position generally parallel to the table edges, said armrest members arranged in horizontal positions extending outwardly from the table edge at angles set by a user for maximum comfort, said wrist support member having a downwardly facing, generally planar portion spaced from said forward ends of said armrest members and disposed opposite the upwardly facing surfaces of said armrest members to provide a clamping space having a vertical dimension which matches the edge of the table for attaching said armrest members and wrist support member to the edge of the table.
Claim 2
Independent Claim
192 words
An apparatus for clamping to a table to support both wrists and forearms of a person while working at the table comprising: (a) a cushioned wrist support member; (b) a pair of cushioned armrest members pivotally connected to said cushioned wrist support member to adjust the angle between said armrest members and said wrist support member; and (c) means at forward ends of said armrest members including a generally planar, upwardly facing surface for attaching said wrist support member and said armrest members to an edge of the table with said wrist support member adapted to be fixed in a horizontal position generally parallel to the table edges, said armrest members arranged in horizontal positions extending outwardly from the table edge at angles set by a user for maximum comfort, said wrist support member having a downwardly facing, generally planar portion spaced from said forward ends of said armrest members and disposed opposite the upwardly facing surfaces of said armrest members to provide a clamping space having a vertical dimension which matches the edge of the table for attaching said armrest members and wrist support member to the edge of the table.
Claim 3
Dependent Claim
29 words
A wrist and forearm support apparatus according to claim 1 further including means for varying the vertical dimension of the clamping space to fit support edges of different thickness.
Claim 4
Dependent Claim
146 words
A wrist and forearm support apparatus comprising: (a) a cushioned wrist support member having a downwardly facing generally planar portion; (b) a pair of spaced cushioned armrest members pivotally connected adjacent forward ends to said wrist support member and extending perpendicularly from said wrist support member, each armrest member having an upwardly facing surface at a forward end; (c) a structural element interconnecting said armrest members at forward ends having said wrist support member attached thereto so that the downwardly facing portion of said wrist support member is disposed opposite to the upwardly facing surfaces of the armrest members; (d) a clamping mechanism carried by said wrist support member and said armrest members to clamp said members to a support, said clamping mechanism defined by said structural element, the downwardly facing portion of said wrist support member and the upwardly facing surface of said armrest members.
Claim 5
Dependent Claim
146 words
A wrist and forearm support apparatus comprising: (a) a cushioned wrist support member having a downwardly facing generally planar portion; (b) a pair of spaced cushioned armrest members pivotally connected adjacent forward ends to said wrist support member and extending perpendicularly from said wrist support member, each armrest member having an upwardly facing surface at a forward end; (c) a structural element interconnecting said armrest members at forward ends having said wrist support member attached thereto so that the downwardly facing portion of said wrist support member is disposed opposite to the upwardly facing surfaces of the armrest members; (d) a clamping mechanism carried by said wrist support member and said armrest members to clamp said members to a support, said clamping mechanism defined by said structural element, the downwardly facing portion of said wrist support member and the upwardly facing surface of said armrest members.
Claim 6
Dependent Claim
53 words
A wrist and forearm support apparatus according to claim 3 wherein said clamping mechanism includes a transverse groove at a forward portion of each of said armrest members providing a space at a connection point with said wrist support member such that an edge of the support fits snugly into the clamping space.
Claim 7
Dependent Claim
23 words
A wrist and forearm support apparatus according to claim 3 wherein said clamping mechanism is adjustable to fit supports edges of different thickness.
Claim 8
Independent Claim
106 words
An apparatus for clamping to a table to support both wrists and forearms of a person while working at the table comprising: (a) a generally rectangular wrist support member; (b) a pair of generally rectangular armrest members pivotally connected at respective forward portions and disposed generally perpendicularly to said wrist support member; and (c) a structural element interconnecting said armrest members and said wrist support members, each of said generally rectangular armrest members having a transverse groove along one lengthwise edge at a forward portion having said structural element disposed in the groove so that said structural element bisects the groove thereby providing a clamping space.
Claim 9
Independent Claim
106 words
An apparatus for clamping to a table to support both wrists and forearms of a person while working at the table comprising: (a) a generally rectangular wrist support member; (b) a pair of generally rectangular armrest members pivotally connected at respective forward portions and disposed generally perpendicularly to said wrist support member; and (c) a structural element interconnecting said armrest members and said wrist support members, each of said generally rectangular armrest members having a transverse groove along one lengthwise edge at a forward portion having said structural element disposed in the groove so that said structural element bisects the groove thereby providing a clamping space.
Claim 10
Dependent Claim
37 words
A wrist and forearm support apparatus according to claim 6 wherein said wrist support member and said armrest members each comprise a generally rectangular beam having a cushion covering substantially the entire upper edge of the beam.
