US Patent 7334830 Tonneau cover

A soft top tonneau cover is formed from a plurality of hinged frame sections that are foldable between overlaying positions and extended positions. Camlock clamps are integrated into the frame so as to provide a stable, quick release latch to the walls of the bed with a minimum of spacial intrusion into the bed. The hinge between the frame sections has a double pivot so as to automatically tension the top when folded open. Strap clamps are integrated into the frame so as to permit the sections to be secured when folded closed.
