Abstract: A tonneau cover system for a pickup truck cargo box comprising a tonneau cover sized and shaped for covering the cargo box. A side rail comprises a first clamping surface adapted to engage the first side of the downward flange. A rod has a rod axis and is mounted on the side rail. A clamp body is mounted on the rod and includes a clamp arm having a second clamping surface adapted to engage the second side of the side rail. A cam is included with one of the side rail and the clamp body. A cam follower engages with the cam. The cam follower is included with the other one of the side rail and the clamp body. Movement of the clamp body along the axis of the rod advances the cam follower along the cam to thereby move the first clamping surface toward the downward flange.

Abstract: A tonneau cover has rectangular elements pivotally connected together. An automatic latch can be coupled to a first rectangular element end of one of the rectangular elements. A latch actuator can extend from the automatic latch to a first latch-rearward rectangular element. The first latch rearward element can be rearward of the first rectangular element end. Movement of the first latch-rearward rectangular element relative to the first rectangular element end, as the tonneau cover moves between closed and open positions, can move the latch actuator which moves the first automatic latch between the latched and unlatched configurations, respectively.

Abstract: A tonneau clamp including a link slidably coupled to tonneau cover; a clamping link pivotably coupled to the link and having a clamping surface; and a handle pivotably coupled to the link and the clamping link and moveable between lowered and upper positions. The handle can be pivotably coupled to the link at a first pivot joint and to the clamping link at a second pivot joint. Handle movement causes the clamping link to pivot relative to the link to raise the clamping surface from an unclamped position to a clamped position in which the clamping surface applies a clamping force against the underside of a ledge of a vehicle cargo box. In the unclamped position the first pivot joint is on a first side of a line and in the clamped position the first pivot joint is on a second side of the line opposite the first side.

Abstract: A tonneau cover system clamp can include first and second clamp members with first and second clamping surfaces, respectively. The second clamp member can be slidably coupled to an elongate member relative to the first clamp member. A locking mechanism can be movable to engage the elongate member to prevent lateral translation of the second clamping surface relative to the first clamping surface in response to the first and the second clamp members being in the locked position. The locking mechanism can be movable to release the elongate member to allow lateral translation of the second clamping surface relative to the first clamping surface in response to the first and the second clamp members being in the unlocked position. A biasing member can apply a biasing force biasing the first clamp member and the second clamp member toward the proximal end of the elongate member.

Abstract: A tonneau cover system includes a cover and a pivot mechanism. The cover includes a plurality of panels hingedly coupled together, and is foldable between an extended configuration and a folded configuration. The pivot mechanism includes a first link bar and a second link bar. The first link bar has an upper end pivotally connected to a forward panel and the second link bar has an upper end pivotally connected to the forward panel. With the cover in the folded configuration, the pivot mechanism may move the stack from an initial stack configuration in which the forward panel is in the first plane to a storage stack configuration in which the forward panel of the cover extends upright along a second plane, and to simultaneously move the forward edge of the forward panel rearwardly and above the first plane.

Abstract: A threaded rod can be pivotably coupled to the tonneau cover via a proximal end. A housing can have first and second housing portions slidably coupled to the threaded rod and moveable along the threaded rod relative to each other between locked and unlocked positions. The second housing portion can include a channel positioned to receive a downwardly disposed distal edge of an inboard flange. Locking pawls within the housing can move to engage threads of the rod to prevent movement of the channel relative to the elongate member when in the locked position. The locking pawls can move to release the threads of the rod to allow movement of the channel relative to the rod when in the unlocked position. A biasing member can apply a biasing force biasing the housing toward the proximal end of the elongate member and biasing the housing toward the locked position.

Abstract: Rigid panel sections can include a rigid panel, a first frame member, a second frame member and a coupling mechanism. The rigid panel can have a first face, a second face opposite the first face, and an edge therebetween. The first face can having a first margin adjacent the edge and the second face can have a second margin adjacent the edge. The first frame member can be disposed along at least a portion of the edge and can have a first flange overlying the first margin. A second frame member, distinct from the first frame member, can be disposed along at least a portion of the edge and can have a second flange overlying the second margin. The coupling mechanism connecting the second frame member and the first frame member together can be positioned outboard of the edge. Methods of assembling the rigid panel sections are also provided.

Abstract: A tonneau cover for covering a cargo box of a vehicle. The tonneau cover includes a plurality of flexible hinges, each of which is between two rigid members. Each flexible hinge includes an elastomeric material having a first portion connected to a first one of the rigid members, a second portion connected to a second one of the rigid members, and a web between the first portion and the second portion. A cut-resistant barrier is associated with the flexible web and bridges between the first portion and the second portion. The cut-resistant barrier is effective to resist penetration by a sharp edge.

Abstract: A clamp to secure a tonneau cover to a frame of a cargo box includes a first clamp member coupled that has a first clamping surface. A second clamp member that has a second clamping surface. A ramp mechanism that causes lateral translation of the second clamping surface toward the first clamping surface, as the clamp moves between clamped and unclamped positions. A cam lock member positioned to engage with the second clamp member and includes a lever for placing the cam lock member in locked or unlocked states. When the cam lock member moves from the unlocked state to the locked state, the second clamp member moves toward the tonneau cover to the clamped position. When the cam lock member moves from the locked state to the unlocked state, the second clamp member moves away from the tonneau cover to the unclamped position.

In the unclamped position the first pivot joint is on a first side of a line and in the clamped position the first pivot joint is on a second side of the line opposite the first side.
