ABSTRACT:
A decorative molding utilizes a tongue and groove system which produces a stable bond between a frame and covering. The frame possesses a projection which corresponds to a groove on the shell, and the two units are slidably engaged to form a connection. This tongue and groove design prevents the shell and frame from being pulled apart except in the direction of the groove. A slot is also provided in the frame to reduce friction between the frame and shell and to alleviate the problem of lateral thermal expansion. A gap is provided in the frame to allow the molding to compensate for linear thermal expansion. This invention not only maximizes stability, flexibility and attractiveness, but also prevents the bowing effect of both linear and lateral thermal expansion on the molding.
