ABSTRACT:
A self-clamping spline and mortice joint is utilized at each of the corners of a rail and stile door. Mortices in each of the rail and stiles extend to the top or bottom edges of the door and a spline is received in the mortices and is exposed along the top and bottom edges of the door. Screws extend through the spline in opposite directions and into the rail and stile functioning to pull the rail and stile together around the spline. The self-clamping joint requires no external clamping. The self-clamping joint may be used on a plank-type door where the spline is L-shaped with one leg extending into the mortices and the second leg extending horizontally over the door and edges to cover the ends of the vertical grooves in the faces of the door. Weatherstripping on the door frame engages the horizontal leg of the spline and prevents transmission of air and moisture from the outside to the inside through the grooves.
