  • Patent number: 6162071
    Abstract: An electrical receptacle adapted to be recessed into a work surface, having a concealed compartment containing electrical ports for connection to a remote power supply and communications devices and an exposed compartment for connecting electrical cables to the ports. The ports are mounted on a partition plate isolating the exposed compartment from the concealed compartment, which is disposed at an oblique angle relative to the work surface to facilitate the connection and detachment of electrical cables and reduce clutter in the work space. The receptacle housing is preferably formed from components which are longitudinally linear, and are thus able to be extruded from aluminum and formed to interlock so that the housing can be assembled without welding. In the preferred embodiment the front portion is engaged to the rear portion along a slip-fit interlock and the partition plate is engaged between the front and rear portions in snap-fit relation.

  • Patent number: 5799803
    Abstract: A cantilevered shelf system includes a shelf bracket having an upper jaw, a lower jaw extending beyond the upper jaw and a back plate adjoining the upper jaw and the lower jaw, and a shelf having a top face with an engaging surface which contacts the upper jaw as the shelf is mounted into the bracket. The shelf has a bottom face with a rear cam edge and a longitudinal groove forwardly of the cam edge for insertion of a projection on the lower jaw. The distance between the cam edge and the engaging surface is slightly greater than the distance between the upper jaw and the lower jaw, so that the cam edge splays the jaws apart as the shelf is being mounted and the shelf snaps into a mounted position in which the projection is seated in the groove. When the shelf is fully mounted the cam edge resists upward displacement of the shelf and the projection prevents forward displacement of the shelf.
