ABSTRACT:
A mortise-and-tenon joint for assemblying three or more components. The mortise receives a pair of opposed tenons with their end surfaces in contact inside the mortise. The tenons are in substantially play-free mating engaging with the mortise and are substantially of the same volume as the mortise. In one embodiment the tenons are right trapezoidal in contact along their inclined surfaces of equal slope. In another embodiment there are two pairs of tenons for each mortise which comprises a pair of cylindrical cavities. Threaded fasteners extending through appropriate hole with internally threaded bushes and apertures in the tenons and through the mortise secure the assembled joints.
