Abstract: An upright storage cabinet has a lock assembly which operates a vertically movable lock bar to simultaneously lock all drawers of the cabinet. The lock assembly includes a rotatable cam body which has a resiliently deflectable cam that projects radially therefrom. The cam body is rotatable between a locked position wherein the cam rotates a drive element to vertically displace the lock bar into engagement with the drawers, and an unlocked position wherein the cam allows the drive shaft to return to an initial position which disengages the lock bar from the drawers. The cam generates a driving force on the drive shaft during rotation of the cam body and is also resiliently deflectable to accommodate dimensional variations which varies the radial position of the drive shaft relative to the drive element.

Abstract: A wall having an interior channel extending vertically along one and preferably both end edges thereof. This interior channel is closed by an openable door arrangement which can be hingedly moved into an open position so as to uncover one side of the channel and permit cables to be laid directly therein. The door arrangement is externally covered by a portion of the flexible side mat which extends over the entirety of the panel side, including the door, so as to permit the portion thereof over the door to hinge outwardly when the door is opened so that removal of the side mat is not required. The side mat is formed as a continuous covering so as to avoid undesired seam or joint lines.

Abstract: A portable, prefabricated panel adapted to be connected with a plurality of similar panels to form a wall or partition structure. The panel is electrically prewired and includes electrical power blocks disposed adjacent the opposite lower corners of the panel, which power blocks are connected by electrical cables which extend internally of the panel. When two or more panels are connected together, electrical power is transmitted between each adjacent pair of panels by a flexible electrical connector which plugs into the power blocks of the adjacent panels. The panel also has electrical sockets integrally associated therewith, which sockets are preferably associated with the power blocks. The power blocks are symmetrical so that the same electrical connections can be made on either side of the panel. A channel-like raceway extends along the bottom edge of the panel for permitting the hidden storage of communication cables.

Abstract: A raceway structure for association with a wall panel so as to enclose and confine power and communication cables which extend longitudinally along the wall panel and longitudinally throughout several series-connected such panels. The raceway structure utilizes a pair of side covers which removably attach to the wall panel and cooperate to define a raceway for enclosing therein electrical terminals and communication cables. The raceway structure has access openings for providing convenient access to the electrical terminals, such as by permitting an electrical receptacle, power feed, or communication cable to be positioned therein or passed therethrough.

Abstract: A space divider panel having fabric sheets positioned to extend across the side surfaces of the panel, with the edges of the fabric sheets being held by channel-like retainers which extend longitudinally along the panel edges. The improved retainer relies upon a spring-type clip for permitting secure holding of the fabric edge, which clip simplifies insertion of the fabric edge into the retainer while effectively providing a secure one-way holding of the edge to prevent its withdrawal. The spring clip solely holds the fabric edge, and accomplishes this without requiring the use of a deformable bead or strip.

Abstract: An attachment structure for mounting a furniture component, such as a work surface member, on the slotted uprights of a wall panel. The attachment structure is releasably engageable with both the slotted upright and the work surface member, such as a desk top. A hook-carrying support is releasably attached to the upright, and the support in turn has the work surface member releasably attached thereto. A latching device, as mounted on the support, automatically engages the slotted upright to fixedly lock the support thereto only when the work surface member is mounted on and properly engaged with the support. The latching device also causes the front edge of the work surface member to be locked down against the support.
