  • Patent number: 10814706
    Abstract: A tonneau cover for covering a cargo box of a pickup truck. The tonneau cover includes a cover assembly having at least one panel and a clamp assembly having a clamp base and a clamp. The clamp base is supported by the panel and has portions defining multiple discrete pockets, each of which includes a seat defining a mounting position for the clamp. The clamp including a hanger with a portion shaped to engage the seats. A clamp jaw is freely and slideably mounted on the shank, and a clamp actuator is in fitted engagement with the shank to move the clamp jaw between engaged and disengaged positions. In the disengaged position, the hanger is moveable from the seat of one pocket to the seat of another pocket, and in the engaged position the tonneau cover is retained over the cargo box of the pickup truck.

  • Patent number: 10730375
    Abstract: A tonneau cover for a pickup truck. The tonneau cover includes a first panel, a second panel and hinge assembly pivotally connecting the two panels. The hinge assembly has first and second pivot members fixed to respective edges of the panels. The pivot members including a cylindrical portion within which a pivot pin is received. The hinge assembly also includes a base member positioned between the two pivot members. The base member is connected to the pivot pins so as to be pivotally moveable relative to the two pivot members. With this construction, the base member is pivotable relative to the second pivot member, and the first pivot member and first panel are pivotable relative to the base member so that the first panel is foldable into a position where the first panel overlies the second panel.
