Abstract
A corner connector for board shaped component parts for manufacture of boxes, drawers and the like is characterized in that a middle part, from which tenons project to both sides, is formed as a plastic sheeting hinge. There are formed on both sides of the hinge line inwardly projecting formations which interengage at the back in the angular position. The middle part forms in an inswung closed condition a post of rectangular cross section.

A corner connector for board shaped component parts comprising:
- a hinge member of a continuous sheet of plastic material having a first half and a second half formed and connected to pivot about a hinge line, each of said first and second halves having a flat outer surface, a flat inner surface parallel with said flat outer surface, a first edge surface defining part of said hinge line, and a second edge surface spaced from said first edge surface a distance equal to the width of said flat outer and inner surfaces, a first side wall extending transversely to said flat inner surface of said first half at said second edge surface, said first side wall being formed integrally with said second edge surface of said first half, a second side wall extending transversely to said flat inner surface of said second half at said second edge surface, said second side wall being formed integrally with said second edge surface of said second half, said first and second side walls both extending parallel to each other and a similar distance from their respective edge surfaces, a plurality of means for engaging the board shaped component parts extending outwardly from each of said first and second side walls in a direction perpendicular to said second edge surfaces and away from said hinge line formed by said first edge surfaces of said first and second halves, first means extending perpendicularly from said flat inner surfaces of said first half away from said flat outer surface for interengaging with similar means on said flat inner surface of said second half, and second means extending perpendicularly from said flat inner surface of said second half away from said flat outer surface similar to said means on said flat inner surface of said first half for interengaging therewith, whereby when said first and second halves are pivoted about said hinge line said means for interengaging on said flat inner surfaces of said first and second halves are locked together to thereby form the corner connector.
