Abstract: An adjustable keyboard support assembly including a keyboard tray support bracket; a work surface mounting bracket adapted to be coupled to a work surface; a connector mechanism having one end coupled to the work surface mounting bracket and an opposite end coupled to the keyboard tray support bracket, the connector mechanism comprising a support arm coupled to the keyboard support at an outer end, such that the keyboard tray support bracket is rotatable about a horizontal axis with respect to the support arm; an angle control mechanism between the keyboard tray support bracket and the support arm for locking the keyboard tray support bracket at a desired angular inclination with respect to the support arm, the angle control mechanism including a spring exerting a clamping pressure on the support arm and the keyboard tray support bracket and a spring lifter for repositioning the spring so as to relieve the pressured applied to the support arm and the keyboard tray support bracket; and a lever control bar coup

Abstract: A mouse pad support adapted for mounting to a keyboard support and having a platform adapted to support a computer mouse, a connector arm adapted for mounting to the keyboard support, and a joint mounting the connector arm to the platform for swivel movement of the platform with respect to the connector arm. The joint typically includes ball and socket portions. The mouse pad support has a connector adapted to removably mount the connector arm to a complementary pocket in the keyboard support without the use of tools. A keyboard support includes a first platform having a pocket for receiving a connector on a connector arm, and a second platform adapted to support a computer mouse, the connector arm extending between the first and second platforms for detachably mounting to the first platform and for adjustably mounting the second platform relative to the first platform.
