Abstract: Joints and connector mechanisms for use in a modular wall system which consists of a series of interchangeable panels that may be combined in various ways in order to create a business environment encompassing of a series of private offices. A joint is adapted for disposition between two sections of a movable wall for interconnecting the sections. Each section includes a panel having an elongated vertical edge defines by a pair of spaced parallel walls. The joint generally comprises two elongated vertical posts each including a mounting strip for mounting the posts to the edges of adjacent panels. A pair of spaced parallel tongues extends outwardly from the mounting strip away from the edge of the panel. First and second flexible connecting strips have first and second flange-receiving portions. In use, each of the strips is positioned between adjacent tongues of the first and second posts for receiving the tongues in each of the flange-receiving portions.

Abstract: A corner work center includes a mounting unit for a computer and like equipment which quickly attaches to two adjoining surfaces at the same height. The unit eliminates the need for an expensive and complex intermediate or third top and the requisite hardware. The unit includes an elevated plate mounted on the frame and a forward tray or bridging surface which is captured by the frame and extends forwardly of the frame at a lower elevation and bridges the included angle between the adjoining surfaces. The unit may also include an articulating arm assembly having a positionable keyboard tray which may be positioned beneath and forwardly of the forward tray. With the arm assembly the keyboard tray can be extended for use or retracted when not in use. The tray includes handles and adjustable bumpers. The unit also includes one or more swing arm supports secured to the frame to position computer components or accessories at desired locations for effective use.

Abstract: A space divider system utilizes horizontally extending beams mounted on height adjustable legs. The system includes main beams on which are two enclosed wire raceways at substantially work surface height. Also included are stabilizer beams which may be attached at their inner ends to any point along the main beam between the legs. The outer ends of the stabilizer beams are connected to a relatively short transverse beam which includes height adjustable posts or legs at each end. The outer end of the stabilizer beam may optionally be connected to the center of the transverse beam or to either leg or to a leg alone to form a T, I or L-shape configuration. The stabilizer beam and transverse beam have the same configuration and may support work surfaces or other components. Work surface such as table tops may also be supported from the legs at the ends of the transverse beams.

Abstract: A door hinge assembly includes a frame and a door with top and bottom hinge pivot assemblies. The top hinge pivot assembly includes a plate fixed to the frame and thereabove a parallel vertically movable plate. The upper plate includes a downwardly projecting hinge pin which projects through a clearance hole in the fixed plate. The fixed plate also includes an upwardly extending guide pin which extends through a clearance hole in the upper plate. A screw extends through the fixed plate and is threaded into the upper plate. When the screw is loosened the upper plate and thus the hinge pin may be pushed up, or permitted to drop into place. By tightening the screw the hinge pin is locked in its extended position and the screw head is flush with the bottom of the fixed plate. The bottom hinge pivot assembly includes an L-shape bracket with the vertical leg secured to the frame and the horizontal leg beneath the door.

Abstract: An improved and more versatile space divider system for open office interiors includes as a major component a structure beam or spine supported at each end by vertically adjustable legs. Feet on the legs provide the required lateral stability to support or hang components such as work surfaces, filing systems and the like from the beam. Each beam includes two enclosed electrical ducts on the top thereof superjacent work surface height, such ducts being provided for power and communication wiring respectively, with the latter being above the former and laterally enlarged. The power wiring duct is prewired with outlets on both sides, while the communications wiring duct includes both lateral and top access. The legs have a smooth exterior surface yet permit beams to be connected thereto at a wide variety of angles. Enclosures or fillets for the beams and legs permit the ducts to pass through the legs fully enclosed.

Abstract: A locking system for a filing cabinet which permits only one drawer to be pulled out at a time includes a vertical track at the side of the cabinet in which move vertically extending bars, one for each drawer, against the pressure of a spring through a predetermined limited distance. When the cabinet is locked the bars are held against any movement. When the cabinet is unlocked, such movement is permitted. When one drawer is withdrawn, a two position cam on the respective bar is rotated 90.degree.. The cam is rotationally mounted on one bar but bears against a projecting shelf on the next adjacent bar or a fixed shelf. When the cam is rotated by the respective drawer being pulled out further movement of the bars is precluded locking all of the other drawers against withdrawal.

Abstract: An assembly for supporting and storing paper, reference materials and other like items on a space divider and furniture system off of work surfaces includes paired hanging vertically extending brackets having one or more horizontally projecting cantilevered arms. Each bracket includes an upper hook and alternative forms of a lower foot which maintains the brackets vertical and the arms horizontal. The hook and feet are removably secured to the ends of the brackets and the alternative feet are employed depending on the height at which the assembly is mounted on the space divider system. The brackets may be mounted anywhere along the space divider system. The arms in turn support with a snap fit several forms or sizes of molded plastic trays which interconnect the paired brackets. The arms are circular in section and the edges of the tray are provided with downwardly turned circular edges which snap over the arms. Projections partially closing such openings assist in retaining the trays on the arms.

Abstract: A sound and visual partition screen panel utilizes a treated corrugated cardboard septum to which is secured a frame. Acoustic insulation pads are provided on each side of the septum within the frame. The frame is designed with rounded vertical and top edges which are adapted to receive a fabric covering in the form of a sewn sock or sleeve which includes seams with inwardly formed welts adapted to be threaded into recesses in the verticals which open to the edges of the panels through a very narrow slot. The top and bottom of each vertical is provided with a removable pin, the one on the bottom also adjustably supporting the panel, which pins in turn secure plastic blocks having semi-circular gear segments, the gear teeth projecting just beyond the rounded surface of the verticals. The gear teeth extend for only slightly less than one half the height of the semi-circular face of the block. The blocks may be inverted by removing and replacing the pins.

Abstract: A lamp for use with a recline chair, or like item of furniture includes a pedestal, a horizontally extending light fixture and a three-link parallelogram linkage supporting said fixture from said pedestal. The pedestal and fixture include parallel surfaces extending approximately 45.degree. to the horizontal in which the links are mounted with ball and socket joints. Two of the links extend beyond the ball joints and are interconnected by short transverse links. In the pedestal the connecting transverse link is connected to one or two tension coil springs balancing the light fixture in any position. The pedestal may support a cantilever table to serve as a side table for the furniture used with the lamp. The fixture may include a semi-cylindrical reflector with pivotal shades at each edge.

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.
