<p>This specification discloses a tube connector system adapted to convenient and removable assembling of square, round or other shaped hollow tubes. It finds use in the construction of temporary and permanent store displays, furniture, shelves, and the like. In one embodiment the connector comprises a joining member having a plurality of insertion members each of which in closely but slidably fitted to the aperture in the end of a hollow tube. Each insertion member has a plurality of recesses on the side thereof. Each recess is provided with a resilient spring member, said spring member having a portion resting on the bottom surface of said recess, and a portion protruding above the top of said recess, permitting forceable entry of the insertion member and retaining it removably in place in the tube. No rotation of the parts is necessary for secure assembly, and no external parts such as screws, bolts, and the like are needed. A joining member involving a plurality of these insertion members can be used for assembling various types of structures, including two or three dimensional assemblies. In a preferred embodiment this spring member is formed from substantially flat spring metal such as spring steel, and is curved to provide a force fit between the insertion member and the inside wall of the tube.</p> |
