Patent ID: 8454254

Claim:
An adjustable keyboard support assembly for adjusting a tenting angle of a pair of keying modules by supporting an inner lateral end of each of the pair of keying modules at different user-selectable heights, the adjustable keyboard support assembly comprising: a pair of lift modules, each lift module configured to be fixedly coupled with respect to a lower portion of a respective one of the pair of keying modules at the inner lateral end thereof for spacing the inner lateral end of the respective keying module from a resting surface and configured to fix the respective keying module at a variety of tenting angles between the lower portion of the respective keying module and the resting surface, each of the lift modules including a coupling portion and at least first and second limbs, each of the first and second limbs being pivotably coupled with respect to the coupling portion of the respective lift module to pivot about a common pivot axis, the orientation of the first and second limbs with respect to the coupling portion and with respect to each other being variable to allow for varying of the tenting angle of the respective keying module, and wherein one of the first and second limbs of each respective keying module includes a stabilizing structure configured to transmit force directly between the first and second limbs when the stabilizing structure contacts the other one of the first and second limbs as the first and second limbs collectively support the keying module in at least one of the variety of tenting angles.
