Connector

Claim 1

A connector for interconnecting lengths of square tubing to form frameworks comprising, in combination, a three-dimensional central body member having a plurality of facets in each of which is formed a threaded bore, and a plurality of separate connectors adapted to be releasably secured by said bores to selected facets on the body member to provide any one of a number of possible configurations, the connector members in turn being adapted to be releasably connected to the lengths of square tubing, characterized in that: (a) each connector member is a hollow tube, of square cross section throughout its length and closed at one end by a wall; (b) a central hole is formed in the end wall of each connector member to accept a screw by means of which the connector member may be secured to the central body; (c) each connector member is adapted to accommodate the head of the screw within it; (d) a recess is formed in each facet adjacent its threaded bore and radially spaced therefrom; (e) the external face of the end wall of each connector member is formed with a complementary protuberance adapted to engage one of the recesses on the central body to prevent rotation of the connector member when secured to the central body.
