Support apparatus with dual palm rests for keyboards and the like
First Claim
1. A support apparatus comprising:
- a base portion defining a working surface on which to place an item to be supported;
at least one abutment member defined on the working surface for abutting a rear portion of the item on the working surface;
dual palm rests positionable in various clamping relationships against a front edge of the item on the working surface toward the abutment member ;
a carriage movably connected to the base portion for displacement of the dual palm rest in a front to back direction relative to the front edge of the item;
interconnecting means for interconnecting the palm rests with the carriage such that each palm rest can swivel about a swivel axis generally perpendicular to a plane defined by the displacement of the carriage, and such that each palm rest is hinged about a hinge axis that extends in a plane generally perpendicular to the associated swivel axis; and
,biasing means for biasing each palm rest about the swivel and hinge axes thereof, and for biasing the carriage toward the front edge of the item on the working surface;
wherein the carriage, dual palm rests, biasing and interconnecting means cooperatively effect a multiply adjustable clamping action on front edge portions of the item on the working surface.

Abstract
A support apparatus has dual, or left and right, palm rests. The apparatus is positionable to support an item like a keyboard in various inclined positions. The dual palm rests are mounted separately on a common carriage that slides in a plane back and forth relative to a front edge of an item on the apparatus. The manner of mounting the palm rests permits each palm rest to swivel about a generally vertical swivel axis and, additionally, move hingeally about a hinge axis that extends in a plane generally perpendicular to the associated swivel axis. The palm rests are connected to sets of torsion springs or the like to normally bias the palm rests about both the swivel axes and the hinge axes for clamping. Likewise, the sliding action of the carriage is preferably normally biased for clamping as well. Overall, the carriage, dual palm rests and biasing cooperatively effect a multiply adjustable clamping action on the from edge of the item. The support apparatus optionally includes a dual side-pad assembly positionable in either left or right use positions, or in a storage position. Each side panel is independently inclinable, and can carry a clip-on wrist rest. The side panels provide surfaces for use, for example, with a cursor positioning device like a mouse or a trackball. For the cursor positioning device, there is also a storage device which is removably attachable to the edges of the support apparatus, for releasably storing the cursor positioning device during non-use.

13. A support apparatus comprising:
-
a base portion defining a working surface on which to place an item to be supported; a palm rest assembly positionable in various clamping relationships with a front edge of the item on the working surface; the palm rest assembly including a carriage movably connected to the base portion for displacement in a front to back direction relative to the front edge of the item; the base portion defining a passageway below the working surface, the passageway extending in a left to right direction relative to the front edge of the item on the working surface; a dual side-pad assembly, slidably disposed in the passageway, comprising left and right side pads interconnected with a shaft for counter rotation relative to each other; wherein the dual side-pad assembly has a storage position generally occupying the passageway, and left and right extended positions in which one of the left and the right side pads extends out from below the working surface; the dual side-pad assembly further having relatively extreme left and right extended positions in which one of the left and the right side pads respectively is permitted to be rotated to various inclined positions relative to the working surface. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
