  • Patent number: 7837282
    Abstract: A cabinet includes side panels, a back panel, and a top panel that frictionally-attach together with non-intrusive integrally-formed connectors. The illustrated base is screw-attached, and includes openings for routing wiring within the cabinet. Brackets are adapted to support shelves in the cabinet in either a flush or inset condition, and at different heights based on which cabinet slots they engage and based on their orientation in those slots. A light-transmitting top panel and top shelf can be used to provide improved light within the cabinet. Hinge brackets on the cabinet support either a thick door with internal storage space, a proud door or an inset door. Drawers supported in the cabinet include a lock within the drawer's header for operating a vertical cabinet lock rod.

  • Patent number: 5632166
    Abstract: A locking mechanism for furniture unit is provided which utilizes a single component for translating rotary motion of a tumbler cylinder of a key lock into reciprocating, linear motion of a pair of opposing lock rods. The mechanism includes a base having a pair of linear guide channels which are defined by spaced sidewalls, a lock rod received in each of the linear guide channels, each of the lock rods having a radially extending projection engaging the sidewalls of one of the guide channels, a key lock, and an actuator which is attached to a drive shaft connected to the tumbler cylinder of the key lock. The actuator includes a pair of arcuate channels, each of which is at least partially defined by spaced camming surfaces which engage opposing sides of the projections on the lock rods, whereby rotation of the actuator in one direction retracts the rods to the unlocked position and rotation in the opposite direction extends the rods to the locked position.

  • Patent number: 5057039
    Abstract: An electrical or communications monument for selective mounting along an edge of a work surface which may have a predetermined minimum spacing between the edge and an adjacent obstruction. The monument includes a one-piece bracket having a back portion from which a base and first and second spaced support arms extend. The base joins the back portion with a curved section which has a predetermined relative large radius. The back portion extends above the support arms to provide a flange upon which a receptacle is mounted. The curved section enables the bracket to be mounted along an edge of a work surface, notwithstanding a closely spaced wall, with the support arms resting upon the work surface. A screw is threadedly engaged with the base. Engagement of the screw with the lower side of the work surface provides a firm three-point support for the monument.
