TONNEAU COVER SYSTEM AND SIDE LOCK CLAMP

摘要

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.

主权项

1. A tonneau cover system for a cargo box of a pickup truck, the cargo box comprising a frame, the tonneau cover system comprising:
a tonneau cover for covering the cargo box, and a clamp to secure the tonneau cover to the frame, the clamp comprising: a first clamp member coupled to the tonneau cover and having a first clamping surface; a second clamp member coupled to the tonneau cover and having a second clamping surface, the second clamp member being moveable relative to the first clamp member between an unclamped position and a clamped position; a ramp mechanism including at least one ramp surface between the first and second clamp members shaped to cause lateral translation of the second clamping surface toward the first clamping surface in response to movement of the second clamp member toward the tonneau cover as the clamp moves from the unclamped position to the clamped position; and a cam lock member positioned to engage with the second clamp member and including a lever for placing the cam lock member in a locked state or an unlocked state, wherein the cam lock member causes the second clamp member to move toward the tonneau cover as the cam lock member moves from the unlocked state to the locked state and causes the second clamp member to move away from the tonneau cover as the cam lock member moves from the locked state to the unlocked state.
