Abstract:

A portable partition panel is provided for open office plans, and the like, and includes a panel frame and removable cover panels that removably attach thereto. Clips on the cover panels releasably engage side frame segments of the panel frame, and hooks on the bottom of the panel frame releasingly engage mating apertures on the cover panel to form a detachable interconnection therebetween. A top cap includes a catch which pulls the cover panels against the panel frame as the cap is installed to assist in securely, yet removably attaching the cover panels to the panel frame. Connectors on the cover panels can be removed and reinstalled, so that the cover panels can be installed in a second orientation to hide mars upholstery tears, and the like. Also, the panel frame includes an upwardly open channel for receiving articles such as wires in a raceway. The upper segment of the panel frame further includes a reduced cross-section that allows cables to be routed from the utility channel into the interior of the partition panel.

Abstract:

A freestanding privacy screen comprises a plurality of like panels shaped to be positioned in a side-by-side relationship. Each panel includes a frame on which an insert panel can be mounted, and hollow side members or uprights. A pair of hinge rods are positioned in the hollow uprights of the frame for axial rotation therein, and have first key members positioned adjacent opposite ends thereof. Panel connectors interconnect adjacent panels in a mutually vertically aligned relationship. Each panel connector has a two-part body construction interconnected by a removable fastener to capture associated end portions of adjacent hinge rods therebetween. The connectors have second key members that mate with the first key members on the hinge rod ends which rotationally interconnect adjacent hinge rods, such that when the privacy screen panels are pivoted, the hinge rods retain adjacent panels in their vertically aligned relationship.
