Abstract: A tonneau system for a pickup bed comprising a bracket system connectable with a sidewall of the pickup bed and a plurality of hingeable sections pivotally coupled to each other to define a continuous surface. Each of the plurality of hingeable sections being connected to adjacent hingeable sections to permit at least some of the plurality of hingeable sections to be rolled together into a generally circular cross-section to selectively reveal the pickup bed.

Abstract: A tonneau cover system for a cargo box of a pickup truck comprising a plurality of tonneau sections each being pivotally coupled to the other to permit pivotal movement of a first tonneau sections relative to a second tonneau sections between an opened position and a closed position. The tonneau cover system further comprises a side rail member connectable to a side wall of the cargo box, a keeper member downwardly extending from the first tonneau sections for pivotal movement therewith between the opened position and the closed position; and a first keeper pin coupled with the side rail member. The keeper member automatically engages the first keeper pin when the first tonneau section is pivoted into the closed position and automatically disengages the first keeper pin when the first tonneau section is pivoted into the open position.

Abstract: A tonneau system for a cargo box of a vehicle having at least one panel section having opposing edge members. The edge members each have a downwardly extending cam surface engagable with opposing sides of the cargo box of the vehicle to generally self-center the panel section between the opposing sides of the cargo box.

Abstract: A quick release clamp including a first clamp member, a second clamp member, and a clamp handle. The first clamp member has a first gripping surface. The second clamp member has a second gripping surface. The clamp handle has a partially curved outer surface that is defined by a central clamp axis. The cylindrical plug is defined by a central plug axis that is offset from the central clamp axis. The shaft operably attaches the first clamp member and the cylindrical plug.
