Abstract
A keyboard support mechanism is disclosed as including an improved arrangement for supporting a trolley of such mechanism for movement relative to a guide track by which the mechanism is mounted on a work station. The trolley is fitted with two pairs of rollers arranged to roll lengthwise of the guide track within a pair of edge mounted mounting channels thereof and a follower; and the guide track is fitted with guide member having a guide channel adapted to slidably receive the follower while preventing movement of the trolley transversely of the guide channel. The guide channel extends rearwardly of a front end of the guide track, whereby to cooperate with the follower to stabilize an auxiliary surface on which a keyboard is supported against undesired transverse or sidewise movement when in its extended use position, while permitting loose fitting of the trolley within the guide track during a substantial portion of its movement of the auxiliary surface to an from its rearward storage position.
