Abstract
A cover includes multiple panels pivotally connected together and foldable between a stacked arrangement and a deployed arrangement. Side rails are attachable to opposite sides of the cargo box and include ledges. The stack can be rotated between an intermediate position and an upward position in which the stack extends above the plane with the upper surface of at least one section disposed at an angle intersecting the plane. A slidable member can slide along a side rail and support a cam lock mechanism moveable between locked and unlocked positions. A link arm can be coupled between the slidable member and the stack to require movement of the slidable member longitudinally along the side rail in response to movement of the stack between the intermediate position and the upward position.
Claims20
A tonneau cover system for a cargo box of a truck comprising:
- a cover comprising at least one section mountable to the cargo box and rotatable into an upward position in which the section extends above the cargo box;
- at least one side rail;
- a slidable member comprising a body slidably coupled to the side rail and a post protruding from the body;
- a cam lock mechanism mounted on the post and movable between a locked position, in which the cam lock mechanism engages the side rail preventing longitudinal movement of the body along the side rail, and an unlocked position, in which the body is permitted to slide longitudinally along the side rail;
- and
- a link arm between the post and the section to require movement of the slidable member longitudinally along the side rail in response to movement of the section into the upward position.
A tonneau cover system for a cargo box of a truck comprising:
- a cover comprising a plurality of panels pivotally connected together, the plurality of panels comprising a forward panel having a forward edge and a rear edge, the panels being foldable between a deployed arrangement wherein the panels are deployed with the forward panel in a forward position, and a stacked arrangement wherein the panels are folded onto the forward panel to form a stack;
- at least one side rail attachable to at least one lateral side of the cargo box, the side rail comprising a longitudinally extending ledge and a longitudinally extending open channel adjacent the ledge;
- a slidable member comprising a body received within the open channel and a post extending through a slot of the open channel;
- a cam lock mechanism mounted on the post and movable between a locked position, in which a wall of the side rail adjacent the open channel is frictionally sandwiched between the cam lock mechanism and the body preventing longitudinal movement of the slidable member along the open channel, and an unlocked position, in which the slidable member is permitted to slide along the open channel;
- and
- a link arm is coupled between the post and the forward panel;
- wherein the stack is rotatable between an intermediate position, in which both the forward and rear edges of the forward panel are adjacent the side rail, and an upward position, in which the rear edge of the forward panel is spaced above the forward edge of the forward panel and the side rail;
- and
- wherein the link arm is coupled between the post and the forward panel to require movement of the slidable member longitudinally along the open channel throughout movement of the stack between the intermediate position and the upward position.
