Modular frame for door or window has interlocking edge elements that align the frame edges in all directions

摘要

A modular construction frame for a door or a window has the adjoining frame sections (2, 3) connected by a simple press fit coupling (16, 17) at the corner, with the one frame section positioned onto the other section at right angles using self aligning couplings. The couplings align the frames in all directions and require no additional adjustment in alignment. The frames support the window/door and provide supports the window/door mechanism.
