Abstract
Abstract A portable palm, wrist, or forearm (appendage) rest is disclosed which includes the rest (1), adjustable supports (2), work surface, computer, typewriter, keyboard, or data input device attachment (3), means for reducing resistance to movement (4), and work surface protector (5). The said device provides a light, portable means for supporting a computer, typewriter, keyboard or data input device user's palms, wrists, or forearms in order to alleviate fatigue and increase productivity wherever the aforementioned device is used.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
175 words
An improved rest for appendages operable to be mounted on a work surface adjacent to a data input device such as a keyboard or computing device, comprising: (a) said rest having a base mounted on the work surface adjacent the data input device being in a complementary shape relative thereto; (b) means for releasably connecting said base to the data input device; (c) support means connected to said base and engagable with the work surface to selectively adjust the work surface to selectively adjust the height of said base relative to the data input device to achieve a proper working relationship between the user's appendage and a keyboard of the data input device; (d) a work surface protector secured to said base to contact the work surface; (f) said work surface protector constructed of a material that reduces frictional contact between said rest and said work surface, whereby said rest may move easily and not damage the work surface; (g) said work surface protector comprising a wheel member, a roller member, or a ball bearing.

Claim 3
Dependent Claim
153 words
An improved rest for appendages operable to be mounted on a work surface adjacent to a data input device such as a keyboard or computing device, comprising: (a) a base means mounted on the work surface adjacent the data input device to receive an operator's appendage thereon; (b) support means connected to said base mans operable to adjust spacing, angular relationship, and height between said base means and the work surface; (c) pad means secured to said base means; (d) covering mounted on said pad means to provide a protective surface; (e) a work surface protector secured to said base to contact the work surface; (f) said work surface protector constructed of a material that reduces frictional contact between said rest and said work surface, whereby said rest may move easily and not damage the work surface; (g) said work surface protector comprising a wheel member, a roller member, or a ball bearing.
Claim 4

Claim 5
Dependent Claim
136 words
An improved rest for appendages operable to be mounted on a work surface adjacent to a data input device such as a keyboard or computing device, comprising: (a) said rest having a base mounted on the work surface adjacent the data input device; (b) means for releasably connecting said base to the data input device; c) support means connected to said base and engagable with the work surface to selectively adjust the height of said base relative to the data input device to achieve a proper working relationship between the user's appendage and a keyboard of the data input device; (d) conductive means connected to said base and a ground connection to dissipate static electrical charges from the operator and said base to ground; and (e) said means for releasably connecting being hook and loop connectors.
