Adjustable computer keyboard support mechanism
First Claim
1. An adjustable platform assembly for attachment of a generally horizontal platform to a generally horizontal work surface and providing means for transporting said platform between a work position and a storage position, while maintaining substantially the same orientation of the platform relative to the work surface, comprising in combination:
- a first member for attachment to said work surface including a first substantially horizontal axis;
a second member for attachment to said platform and including a second substantially horizontal axis substantially parallel to the first horizontal axis;
a support arm pivotally connected at its opposite ends to the first member and the second member, said support arm forming an angle less than 180°
whereby the support arm may transport the platform between the work position and the storage position by pivoting about said first substantially horizontal axis and where the platform is adjustable to a position above or below the level of the work surface; and
a mechanical compensating mechanism mounted on the support arm for altering the orientation of the platform about the second axis with respect to the support arm when the second member and platform are rotated about the first substantially horizontal pivot axis between the work position and the storage position.

Abstract
The present computer keyboard support assembly comprises a platform suitable for supporting a keyboard mechanism having one end of an arm pivotally mounted to the platform and the other end pivotally mounted to a mounting bracket which is attached to the underside of a work surface. A compensating mechanism utilizing a driving mechanism interacting with the pivot mountings for the arm and controlling the orientation of the platform, as the platform is moved to and from a storage and use position.
