A multi-purpose retractable desk or table top is provided for use in conjunction with a shelving or wall system. The system includes vertical standards having channels which typically are receptive to shelf brackets. The retractable desk top is attached to the standards by a linkage and mechanism which enables the top to be infinitely oriented at any angle from horizontal to vertical. In its vertical, retracted configuration, the desk top lies substantially flat against the standards and the linkage is substantially concealed within the standards. The attachment linkage and mechanism is constructed to enable the height of the entire device to be adjusted.

A retractable work surface system comprising: a pair of vertically-extending, laterally spaced elongate standards, each standard defining a longitudinal channel having a rear wall, a pair of spaced sidewalls extending forwardly from the rear wall, said channel having a forwardly facing restricted opening formed along its length and at the forward region thereof, the restricted opening being defined by a pair of flanges extending inwardly toward each other from the forward end of the sidewalls; means enabling each standard to be secured in an upright position without presenting any obstruction in the channel; an upper yoke slidable in each channel; a lower yoke slidable in each channel; means for releasably securing each of said yokes in any position along its respective channel; an upper link associated with each standard, the upper link being pivoted at one end to the upper yoke; a lower link associated with each standard, the lower link being pivoted at one end to the lower yoke; each of the upper links being pivoted to its associated lower link at a common pivot located forwardly of the pivotal connection between the links and their respective yokes; a table secured to the upper links for movement therewith and to connect the linkages for movement in unison with each other; said linkages being movable between a vertial position in which the upper and lower links are in longitudinal alignment with each other and in which at least portions of the upper and lower links are received within the channels in the standards.
