Abstract:
1. Angular corner structures that join universal foldable frame moulding lengths comprising: a. pre-formed polygon angles including triangular, rectangular, pentagonal, hexagonal, and octagonal; b. an exterior side wall body structure in perpendicular intersection with an integral exterior lip body in perpendicular intersection with an integral lip edge body in perpendicular intersection with an integral inner lip body in perpendicular intersection with an integral inner side wall body; c. a hollow perpendicular sleeve or slot or opening bordered by the exterior and inner side wall bodies and the exterior and inner lip bodies and the lip edge body and an integral abutment or stop and forms an interior rabbet or a recess or a shelf or a stop; d. the integral abutment or stop terminates the sleeve and continues to an integral vertex corner; e. the lip body, sleeve, side wall body, and other elements on each side of the integral vertex corner are identically duplicated on an adjoining integral vertex angular body including the lip body, sleeve, side wall body, and other elements.
