ABSTRACT:
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.
