ABSTRACT:
The joint comprises a pair of parallel tongues of uniform thickness on an edge of one member which are pressed into grooves of uniform width in another member. The grooves are inclined from top to bottom relative to each other, bending the tongues out of parallelism and thereby locking them in the grooves to form a self-locking joint equivalent to a dovetail joint. Such tongues on the top and bottom edges of a vertical member are pressed into longitudinal grooves in elongated top and bottom chord members to form an I-beam or truss section. The tongues may be formed on the edge of a board or they may comprise the opposite face sheets on a plywood panel. Also, the joint members may be metal.
