Abstract: 1502970 Furniture joints H-W DUPREE 30 May 1975 [1 June 1974] 23549/75 Heading F2M A corner connector for the manufacture of boxes, drawers and like items of furniture, of the kind comprising a body having a number of tenons or equivalent projections for sliding engagement with mortices in the ends of elongate components, e.g. boards, or panels to be connected, has the body formed of two parts connected together by a sheet plastics hinge, the connector being preferably moulded wholly out of plastics material, and on either side of the hinge there being provided interlocking formations which interengage in snap-in fashion after pivoting of the connector halves through a predetermined angle to form a rigid post having tenons or projections arranged at the predetermined angle for connecting to boards or panels to be secured together at the predetermined angle, e.g. a right angle. As shown, the connector is moulded to provide sets of tenons 10, 11, 13, 14 each set projecting outwardly from a wall 15 which is integral with a hinge structure comprising plates 18, 19 interconnected by an integral thin flexible plastics hinge 17. The plate 18 together with the associated wall 15 forms one half of the connector body and the plate 19 together with the other wall 15 forms the other body half. Complementary interlocking formations are formed on end plates 22, 20 of the respective body halves and at intermediate locations such that when the body halves are swung about the hinge 17 through 90 degrees these formations interlock so that a rigid post of rectangular section is formed from which the two sets of tenons 10, 11, 13, 14 project at right angles to each other. The outermost tenons 10, 14 are either offset from the plane of the outer surfaces of the plates 20, as shown, so that the body lies between square cut ends of the boards or panels when the tenons are inserted into the mortices (Fig. 1, not shown) or are flush with the plane of the outer surfaces of the plates 20, so that the body is, when assembled with the tenons inserted into the mortices in the boards or panels and mitred end surfaces of the latter are brought into engagement, totally enclosed within hollow spaces in the ends of the boards or panels (Fig. 4, not shown). Fig. 15 shows a modification of the former arrangement wherein the outer surfaces of the end plates of the body are of quadrant form and abut each other instead of overlapping. The interlocking formations comprise wedge formations 23 on end plates 22 which engage complementary recesses on the inner faces of end plates 20 and inner plates 21, pins 26 which engage in undercut grooves, Fig. 11, in a slot formed in a block 25, and a tongue 31 having a hook formation at its end such that it can be forced through an aperture 33 in a flange 34, Fig. 13.
