ABSTRACT:
A connector which may be readily assembled to and disassembled from a guideway, such as, in particular, a box-shaped channel, for the construction of knockdown furniture, shelving and the like. This knockdown connector is characterized by requiring only a standard box-shaped channel without special machining thereof. The knockdown connector and guideway assembly includes a box-shaped channel forming a U-shape transverse cross-section and having opposite internal faces, and a pair of flanges projecting edgewise toward each other. The knockdown connector includes an elongated base member having a pair of lugs at opposite ends thereof respectively; the central portion of the base member is formed with a threaded bore to removably screw a threaded holding member therein; and the lugs are formed with at least one camming face extending transversely to the longitudinal direction of the base member and operatively obliquely relative to at least one of the opposite internal faces.
