Window frame, window frame assembly and method of fabrication

摘要

An improved window frame is provided. The window frame utilizes one or more locking panels coupled to the frame body via a living hinge. In accordance with one embodiment of the present invention, the window frame includes a plurality of frame segments extending between respective corners of the window frame. Each of the frame segments defines a cross section comprising a frame body including a locking structure catch formed therein, a frame locking structure arranged to engage the locking structure catch, and a locking panel secured to the frame body via a living hinge. The living hinge is arranged to permit the first locking panel to pivot relative to the frame body between a closed state and an open state. The locking panel is arranged to engage the frame body and define a window securing dimension between the frame body and the locking panel upon pivoting to the closed state. The locking panel and the frame body are provided with opposing locking panel catches arranged to secure the locking panel in the closed state. The frame body, the locking panel and the living hinge include a co-extruded unit including the opposing locking panel catches.
