Abstract
A wrist support is detachably connectable to a computer keyboard by means of two connector plates which are received within two cavities formed on the wrist support and movable between a stow position where the connector plates are completely received within the cavities and an extended position where an end of the connector plates is extended out of the wrist support to be pivotally connected to the keyboard. Each of the cavities has two side walls each having two spaced flanges defining therebetween a rail for receiving and guiding a lateral side edge of the plate so as to allow the movement of the plate within the cavity. The plate has first paws which are engageable with ends of the flanges to define the extended position and a second paw engageable with stop blocks provided in the cavity to define the stowed position. The second paw is releasable from the stop blocks to allow the connector plate to move from the stowed position to the extended position. By means of such a detachable connection, the keyboard and the wrist support may be packed and sold separately and allow the general consumers to selectively mount the wrist support to the keyboard.
