  • Patent number: 4487522
    Abstract: A device for joining furniture panels comprises a pin (2) in the form of a steel screw having a commonly employed thread on its shank, which can be any of the standard threads used on screws for insertion in wood and chipboard. The screw is inserted into one edge of a panel (4). The screw is symmetrical about its axis so its angular orientation is irrelevant. The other part of the device is a plug-like holding member (8) fitted into a recess (10) in the face of another panel (12). A grub screw (66) is screwed into the holding member (8) and pushes against the head of the screw (2) to clamp the two panels together. Screw (2) can be manufactured cheaply on common screw making machines, does not need to be orientated, has a collar (18) to ensure automatic correct axial positioning, is thin thus involving little risk of bursting the edge of panel (4), and does not need to be of cranked shape for use in relatively thin panels (4).
    Type: Grant

    Date of Patent: December 11, 1984
