Abstract: An adjustable keyboard support device having a keyboard support platform and an arm connected to the platform and adapted for attachment to a base unit. Positioning of the keyboard support platform is secured by frictional engagement of coil springs on cylindrical surfaces. Release mechanisms may be activated to change diameters of the coil springs, unsecuring the engagement of the springs against the surface. Varying spring constants allows progressive release of more than one spring. An adjustable peripheral device support platform is attached to the keyboard support platform. A wrist support is provided at the front of the keyboard support platform, and includes a rack and pinion adjustment of the height of the support surface.

The bottom wall has an upper surface and a lower surface with a pair of integral, opposing guide rails projecting therefrom. Each guide rail has a length oriented substantially parallel to the bottom wall. The middle wall is configured to both resiliently bias the lower surface of the top wall against the working surface of the work surface and resiliently bias the upper surface of the bottom wall against the underside of the work surface, thereby clamping the work surface between the top wall and the bottom wall.

Abstract: This invention is directed to an electrical distribution terminal block and modularly couplable electrical receptacles wherein the terminal block is formed by a plurality of stackable wafers. Each wafer has upper channels formed therein that radiate from a common upper interior intersection point to an outer surface thereof, and lower channels formed therein that radiate from a common lower interior intersection point to an outer surface thereof. When the wafers are vertically stacked, the upper channels of one wafer complementally form ducts with the lower channels of another wafer, each duct having an outlet or port in communication with the exterior of the terminal block. An electrical terminal, formed in a configuration adapted to be received in the upper or lower channels, is disposed in each formed duct and includes connectors for coupling to incoming and outgoing wires of a polarity including neutral, and for coupling that polarity or neutral to a terminal of the receptacle.

Abstract: The invention is directed to a modular electrical outlet including a housing; a pair of plug-in connectors carried by and disposed at opposing ends of the housing; and a conductor disposed within the housing. Each of the connectors includes a plurality of terminal receiving openings. The conductor includes a pair of blade receiving sockets, with a longitudinal axis extending between the blade receiving sockets. The conductor includes a pair of terminals at opposing ends thereof, with each terminal being offset from the longitudinal axis. The conductor may be selectively positioned in the housing at one of two reversible positions. To wit, the conductor may be selectively disposed within the housing in a first position such that each terminal is received within an associated terminal receiving opening of a respective connector, and a second position such that each terminal is received within an associated terminal receiving opening of the other respective connector.

Abstract: A receptacle assembly for multi-wire, multi-circuit power distribution systems for modular wall panels has a body, at least one outlet formed in the body, at least one input plug formed in the body, the input plug have a plurality of openings therein, and three conductors, one line conductor, one neutral conductor, and one ground conductor.
