A lock plug cylinder has a face with a key slot therethrough, the lock plug cylinder received within the lock housing through the orifice in the front face. A mounting bracket has a front face with an orifice, a pair of laterally disposed flanges projecting from the front face, and a pair of retaining flanges projecting substantially perpendicularly from the front face. The lock housing is received between the retaining flanges in such a way as to have the retaining flanges received by respective upper and lower opposing ears.

Abstract: A freestanding framework having a plurality of generally vertically disposed support columns supporting a plurality of generally horizontally disposed overhead beams. The overhead beams include a portion that provides a raceway for the delivery of an electrical conduit. One or more barrier members are connected with framework.

Abstract: A system for defining a plurality of work zones within an otherwise open area. The system includes a framework formed from a plurality of spaced apart poles extending upward from a base surface. The poles are interconnected by a plurality of crossbeams at a height substantially above a standing user. At least some of the poles are adapted to provide a raceway for the delivery of utilities. The system also includes a height-adjustable light fixture connected to the crossbeams. The light fixture extends outward from the crossbeams and is capable of projecting a light beam directly downward on the work zone of a user.

Abstract: A freestanding framework having a plurality of generally vertically disposed support columns supporting a plurality of generally horizontally disposed overhead beams. The overhead beams include a portion that provides a raceway for the delivery of an electrical conduit, and a lower portion formed as an open-sided rail. One or more barrier members are connected with the open-sided rail.

Abstract: A support system having a support member, a bracket and a work surface is disclosed. The support member has a slotted face and a support wall adjacent the slotted face. The bracket has a plurality of teeth adapted to engage the slotted face of the support member. The plurality of teeth include upper teeth and lower teeth. At least one of the lower teeth is sized to pass through the slotted face of the support member and engage the support wall. A work surface is supported by the bracket.

Abstract: A synchronous tilt control mechanism is provided for a chair. The chair includes a base, a seat, a back, a torsion spring, a first slide member and a second slide member. The base further includes a tilt control housing mounted thereon. The back includes a forwardly extending support member. The seat and back are pivotally attached to the tilt control housing. The torsion spring has a forwardly extending leg and a rearwardly extending leg. The forwardly extending leg is mounted to the tilt control housing. The seat slidably engages the support member by way of the first slide member, which is disposed on one of the seat and the support member. The support member slidably engages the rearwardly extending leg of the torsion spring by way of the second slide member, which is disposed on one of the support member and rearwardly extending leg. A downward movement of the seat causes the back to move downwardly and rearwardly against an upward force provided by the torsion spring.

Abstract: A height adjustable table that has a base and a table top. A support is attached to the tabletop where the support selectively engages the base solely via friction so that the tabletop is prevented from moving relative to the base.

Abstract: A stackable wall panel system including at least one upper and lower wall panel and a first and second post. The second post is disposed on the first post. One or more upper wall panels are connected to a pair of lower wall panels having a rail with a pair of draw blocks and a draw rod.

Abstract: A wall panel including a rectangular frame, a pair of wall members and a thin decorative sheet covering the wall members. The frame includes two spaced apart, generally parallel vertical frame members. The horizontal frame members are connected to the vertical frame members at opposite ends thereof to form the rectangular frame. In one embodiment, each of the frame members includes a core member and a pair of sidewall member attached to opposite sides of the core member. The wall member are attached to the sidewalls on opposing sides of the frame members. In another embodiment, inner wall members are attached to the opposing sides of the frame members, and outer wall members are thereafter attached to the inner wall member. A decorative sheet covers the outer surface of each outer wall member. The wall panels are connected to each other with a connector member.

Abstract: This invention is directed to a shelf assembly having a shelf, a mounting block and a barrier member. The shelf has a first edge. The mounting block is attached to the first edge. A barrier member is adapted to be attached to the mounting block. The barrier member is capable of being oriented in at least two positions with respect to the shelf. The two positions include an article retaining position and an article access position.

Abstract: A tiltable chair including a housing, a back support pivotally attached to the housing about a first horizontal axis and a seat support pivotally attached to the housing about a second horizontal axis. A leaf spring includes a first end engaging the housing and a second end biasing the back support and seat support in an upward direction. A fulcrum member is moveably supported in the housing and engages a bottom surface of the spring intermediate the first and second ends of the spring. The chair also include an adjustable backrest and armrests slideably mounted on the back support, and a seat slideably mounted on the seat support. A tilt limiter is provided to limit the rearward tilting of the chair. A selector member includes indicia that indicates the setting of the tilt limiter so as to apprise the user of maximum available rearward tilt position of the chair.

Abstract: A tiltable chair including a base member (44), a seat (32), a back (34), and a linkage assembly (40) adapted to allow the seat and back to tilt downwardly and rearwardly and to allow pivotal movement of the seat about a pivot axis (52) in substantial alignment with the hip joints of a user. Other aspects of the invention are to provide a vertically adjustable column (42) for supporting the seat of the chair, a support assembly including a frame member (33) having a central opening therethrough and a receptacle formed around the perimeter thereof, a carrier member adapted to fit inside the receptacle, and a membrane of elastic material (210) covering the central opening, and a pair of armrests (36) adapted to be mounted to the chair to allow pivotal movement thereof.

Abstract: A machine and method for securing fabric layers to the core of a fabric panel. The machine includes top rollers and side rollers for stretching the fabric layers along the top surface and side surfaces of the core. Staplers preserve the stretch by stapling the edge of the fabric to the side surfaces. A front stapler and rear stapler are also provided for stapling the fabric to the rear surface and front surface of the core.
