Abstract
Abstract A full height partition wall system is characterized by a unitary panel with a vertically movable head panel and a vertically movable foot panel secured thereto and forming a part thereof adapted to be moved upwardly and downwardly, respectively, to secure the panel to and directly against a ceiling and floor, respectively. The system has no posts, but rather a narrow vertical on each end of the panel which has an outwardly directed relatively shallow channel at the top in which is positioned a strut supporting the corresponding end of the head panel. A drive in the form of a small cog is operative vertically to move the strut and thus the head panel, with a spring detent member holding the strut in adjusted position. An adjustable foot is secured to the bottom of each vertical and the foot panel is spring loaded against the bottom of the foot for movement either with the bottom of the foot or movement independently against the spring loading. The vertical further has laterally directed edge flanges flush with the open end of the channel and adapted to be held to juxtaposed edge flanges of an adjacent panel to form a partition wall, and lateral access may be had to the strut drive for vertical adjustment of the head panel without disassembly of the partition wall. The panels include metal face plates formed with locating flanges at inwardly bent vertical edges thereof which cooperate with lateral stops on the vertical properly to position on the face plates the vertical forming the vertical edge of the panel.
