Abstract: An interior partition system wherein with relatively few components, most of which can be roll formed from common sets of roller dies, a wide variety of interior screens or full height partitions can be constructed, thus avoiding the necessity of the manufacture and inventory of a large number of parts. For some parts, where volume may not justify the investment in the required roll sets, other manufacturing techniques may be employed, but such parts are readily compatible with the high volume components and usable interchangeably therewith.

Abstract: A partition head assembly for a partition wall panel is characterized by a telescoping head in the top of the partition panel and a strut at at least one end of the head which is adjustably vertically secured to the partition panel at all vertical positions thereof by a strut retaining clip. Vertical adjustment of the head assembly may be obtained without disassembly thereof and with the panel assembled in a partition wall.

Abstract: A chair of the tilting type which includes a base, a seat and back, with the base pivotally supporting the seat with two opposite non-parallel links of the four bar non-parallel linkage, with one of the opposite links extending to support the back and also being formed to provide an arm rest. The four bar linkage is duplicated on each side of the chair by forming the two opposite non-parallel links or cranks from the upturned ends of the tubes which pass through the base in parallel but vertically offset fashion, the base thus forming the fixed bar of the linkage with its opposite bar or coupler being formed by the seat. A spring within the base is operative on one of the tubes to urge the chair to an upright position. The tubes are pivotally connected to the seat and one of the tubes extends and is fixedly connected to the back in a manner to emphasize the isolated and separate appearance of the seat and back.

Abstract: A light fixture for horizontal or wall task surfaces for office and like interiors adapted to be used with an ambient light system which fixture utilizes a plain rectangular elongated housing for a fluorescent lamp with simplified end brackets which permit the fixture to be mounted directly or indirectly on screens or partitions at any desired elevation, and providing angular adjustment. Direct glare is avoided and veiling reflections reduced by angular selection, lens selection, and recessing the lens within the housing. The adjustment brackets provide precise angular incremental adjustment but are designed to slip if excessive force is exerted on the fixture to avoid damage to the fixture, partition, or screen.

Abstract: A knock-down drawer construction held together by resilient clamps. A pair of front clamps, U-shaped in cross section, are fastened to the rear face of the drawer front by threaded fasteners, such as screws or bolts, and the sides of the drawer are inserted into the clamps. Longitudinal slots along the inside faces of the sides support the drawer bottom, and the drawer bottom is retained in position by the drawer back which is fastened to the sides by corner clamps. The clamps are retained in position by integrally formed tabs which are inserted in transverse grooves on the outer faces of the drawer sides. Clearance recesses along the front edges of the drawer sides are formed adjacent each threaded fastener so that the major portion of the front edges may abut the clamps. The front clamps extend along the full length of the front edge, and notches formed in the clamps adjacent the longitudinal slots allow the bottom to extend forward of the clamps to abut the drawer front.

Abstract: A sheet metal face for a structural panel has at least one edge portion bent and folded to define a recessed double-thickness flange. A plurality of longitudinally-spaced slots in the flange are used for attaching mounting members having upwardly facing hooking projections receivable in a hook pocket integral with a wall-hanging structural unit. A non-metallic protector strip may be interposed between the hooking projections and hook pocket. The structural unit has bottom and rear sheet metal panels with an integral assembly flange and assembly hook. A load bar assembly may be interposed between the mounting members and the structural unit.
