Abstract
The present invention is a joint structure which is particularly adapted for the construction of a frame for windows and doors. The joint structure includes a tenon which is cooperatively connected to a first portion at a mortise which is formed in a second portion. The mortise is positioned and sized to receive the tenon. A first groove is formed in the tenon and is transverse to the tenon. A second groove is formed in the second portion wherein when the tenon is inserted into the mortise, the second groove is aligned with the first groove to form a dowel cavity. A locking dowel pin is inserted into the dowel cavity and provides a resistance to sheer force along substantially the length of the pin.
