Abstract
A modular room divider system has plural upright juxtaposed panels having cylindrical anchor receiving apertures disposed about upright axes in the panels top and bottom surfaces. A coupling assembly has a pair of spaced apart anchors mating with the anchor apertures. Threaded portions having opposingly directed right and left hand threads extend inwardly from the anchors and are centrally engaged by an internally threaded sleeve having adjacent right and left hand threaded portions. The sleeve has a square prismoidal exterior surface and is traverseable by a notched wheel having a mating central aperture. A channel extends from the anchor apertures to the edge of each channel. In use, two panels are assembled by placing them in juxtaposition. The coupling assembly is placed in alignment over the panels, the anchors being lowered into the anchor apertures and the threaded portions over corresponding channels. The wheel is rotated causing opposing axial movement of the threaded portions, thereby moving the anchors and the panels toward each other, the anchors distributing the tensile load upon tightening transversely across the panel. A similar coupling assembly is placed on the bot…
