Abstract
An adjustable platform support mechanism for a keyboard includes a platform and a connecting assembly for the platform. The connecting assembly is attached to the platform by means of first and second pivotal connecting arms. The quadrilateral formed by connecting the pivots is in all instances a non-parallelogram. Thereby the platform, when moved from an extended position to a storage position, is pivoted upwardly in order to increase the space available in the kneehole underneath the desk. The shelf also features an adjustable tilt mechanism associated with keyboard platform support bracket so that the operator will be able to adjust the platform to any one of a number of tilt positions.

An improved adjustable support mechanism for a keyboard platform assembly of the type including a platform supported by said support mechanism, said platform associated with a desk, said support mechanism comprising in combination:
- a mounting plate for attachment to the underside of a desk platform;
- a slide assembly cooperative with the mounting plate and slidable between an extended position and a retracted position;
- first bracket means projecting downwardly from the slide assembly, said first bracket means including an upper pivot and a lower pivot;
- a forward platform for support of the keyboard;
- second bracket means projecting downwardly from the forward platform, said second bracket means including an upper pivot and a lower pivot;
- a first connecting arm between the upper pivots;
- and
- a second connecting arm between the lower pivots whereby the arms and pivots provide a non-parallel, unequal connecting linkages between the pivots, said arms defining means for tilting the platform to a non-horizontal position in the kneehole under a desk top as the platform is moved by pivoting of the arms to the retracted position.
