Abstract: A chair having a metal rod frame back assembly where the frame includes generally horizontal top, bottom and middle members and spaced apart generally vertical side members. Two seat brackets are welded to the middle and bottom members and attach to a seat board and two rod segments are welded to the side members. The seat board is covered with foam and upholstery. The back frame may be covered with springy mesh to give a thin elegant, yet comfortable back structure. Alternatively, foam is glued to a structural material and the material and foam combination and the frame are covered with upholstery. Arms and armrests are attached to the seat board and the seat and back assemblies with arms are mounted to a pedestal connected to a five spoke base riding on casters.

Abstract: A decorative chair base having a metal substructure, a single molded plastic cover and a plurality of decorative inserts. The metal substructure has a central hub and radiating leg portions. At the extended ends of the leg portions are sleeves for mounting casters. The plastic cover also has a central hub and leg portions. The central hub of the cover fits over the central hub of the substructure and each leg portion of the cover overlays a leg portion of the substructure. Each leg portion of the cover has a raised end section, and a recess and there is a raised section surrounding the hub portion. An insert is mounted in each recess so as to be flush with the raised portions.

Abstract: An AC line power coupling system secures a conventional plug (700) of an appliance cord or extension cord (702). A adapter (400) is fitted onto the prongs (704) of the cord, and semi-permanently attached with a connector (300) including two half housings (301 and 302) that fasten over the plug and a clamp (200) that holds the cord. The adapter prongs mate, which have a conventional layout, with a special socket (600). The adapter is locked onto the socket by a sleeve (500). The sleeve moves relative to the socket, rotating and axially sliding. When the sleeve is slid onto the protruding cylindrical end of the adapter and rotated, lugs on the inside of the sleeve engage in grooves, locking the adapter to the socket; the sleeve motion is reversed to unlock. The adapter can be plugged into conventional sockets while the connector remains fastened over the plug, but when plugged into the special socket and locked, the cord is prevented from pulling out under tension.
