Abstract
Abstract A device for providing work surfaces for writing, typing or other such activities, that collapses to an easily storable position and readily reassembles for use. The device includes a plurality of hinged work surfaces of shelves, which are connected to a rear support wall and in the assembled position are also connected to side support walls. The side support walls are, in turn, also connected to the rear support wall. In addition, partition extension walls can be connected and disconnected from the side support walls to provide increased seclusion from adjoining areas when the device is used in a crowded area.

Claim 1
Independent Claim
249 words
A collapsible work station comprising a rear support wall having a front and back surface and a pair of side support walls, means pivotally mounting each of said side support walls to a different side edge of said rear support wall such that said side support walls may be pivoted toward each other and toward said front surface of said rear support wall; a plurality of shelves, the length of each of said shelves being substantially equal to the width of said rear support wall, each of said shelves being pivotally mounted to said front surface of said rear support wall and being movable between a first position wherein said shelves are parallel to said rear wall and a second position wherein said shelves are perpendicular to said rear wall, support means associated with said side support walls for maintaining said shelves in said second position; said means pivotally mounting said side support walls mounting said side walls such that when they are pivoted toward the front surface of said rear support wall and substantially parallel thereto, they are spaced from said front surface of said rear wall a distance at least equal to the thickness of said shelves, whereby said station is collapsed by first pivoting said shelves to their first position wherein they are parallel to the front surface of the rear support wall and thereafter pivoting said side support walls toward said front surface of said rear support wall so that they lie on said shelves.
