1502824 Spigot-and-socket joints RAPID SA 8 April 1975 [11 April 1974] 14363/75 Heading F2M An element 4 of polygonal, e.g. square, crosssection is secured in a recess 5 of polygonal, e.g. square, cross-section of a panel 6, by means of a clamp device 1 of U-shape in section and polygonal, e.g. square, in plan, the side walls 3 being resilient and slightly concave to allow their edges 7 to be pressed into the corners of the recess on assembly, with the end of the element 4 received in the clamp. Portions of the side walls adjacent the web 2 are cut and turned down to form tongues 10 for penetrating the panel 6, and the top edges of the walls have claws 9 for gripping the element 4. The walls 3 diverge slightly before assembly, and have ribs 11 for abutting the sides of the recess 5. A pallet may be made up of two parallel cellular panels 6 joined by spacers 4 by means of clamps 1. |
