ABSTRACT:
A hinge structure is disclosed which is especially suited for use in a double pivot hinge connecting together two panels for pivotal movement in their common plane. Such panels may be the frame members of a folding chair. In each panel, an aperture is provided having a partly circular socket portion and having two opposed abutment surfaces lying transverse to a circular arc centered on the socket portion, and a bushing is located in each socket portion. The two panels are connected by a rod having its opposite ends forming shaft portions rotatable within the bushings and having a lever portion extending along the outer surfaces of the panels and forming a connection between the panels, and having intermediate portions connecting the lever and shaft portions and configured to contact the abutment surfaces to limit pivotal movement of the rod relative to the two panels. The apertures are shaped to allow insertion of the rod member with the bushings mounted thereon, so that the whole hinge assembly can easily be assembled.
