Abstract

A tonneau cover can include at least one pair of cooperating locking elements coupled thereto with the cooperating locking elements being positioned to engage and automatically lock with each other when rearward sections of the tonneau cover are folded onto the forward section and into a stack. Thus, the cooperating locking elements can operate to retain the sections together in the stack when locked with each other.

First claim

What is claimed is:

1. A tonneau cover system for a cargo box of a truck, the cargo box having a forward end, the tonneau cover system comprising:
a tonneau cover including a plurality of sections hingedly coupled together, the plurality of sections including a forward section and a plurality of rearward sections;
the tonneau cover being foldable between a closed configuration in which the plurality of sections are arranged in a first plane to cover the cargo box and an open configuration in which the plurality of sections are arranged in a stack with the rearward sections stacked upon the forward section;
at least one pair of cooperating locking elements coupled to the tonneau cover with the cooperating locking elements being positioned to engage and automatically lock with each other when the rearward sections are folded onto the forward section in the stack, the cooperating locking elements retaining the sections together in the stack when locked with each other.

2. The tonneau cover system of claim 1 , wherein the forward section is mountable adjacent the forward end of the cargo box and a first of each pair of cooperating locking elements is coupled to a forward edge of the forward section.

3. The tonneau cover system of claim 2 , wherein a second of each pair of cooperating locking elements is coupled to the rearward sections at a hingedly coupled edge of an adjacent pair of the plurality of sections.

4. The tonneau cover system of claim 3 , wherein the second of each pair of cooperating locking elements is coupled to a hinge at the hingedly coupled edge of the adjacent pair of the plurality of sections.

5. The tonneau cover system of claim 3 , wherein the second of each pair of cooperating locking elements comprises a latch with a major dimension that extends generally parallel to the first plane in the closed configuration and extends generally perpendicular thereto in the open configuration.

6. The tonneau cover system of claim 1 , wherein a first of each pair of cooperating locking elements is a striker and a second of each pair of cooperating locking elements comprises a latch.

7. The tonneau cover system of claim 1 , wherein the cooperating locking elements are designed to automatically lock with each other under the weight of the rearward sections when the rearward sections are folded onto the forward section in the stack.

8. The tonneau cover system of claim 1 , wherein the pair of cooperating locking elements are coupled to the tonneau cover at fore-aft spaced apart locations, and at least one of the sections in the stack being positioned between the fore-aft spaced apart locations.

9. The tonneau cover system of claim 1 , further comprising at least one biasing member biasing a first of each pair of cooperating locking elements toward a locking position.

10. The tonneau cover system of claim 1 , wherein the tonneau cover further comprises a cab rail forward of the forward section and a first of each pair of cooperating locking elements is coupled to a forward edge of the forward section by being mounted to the cab rail.

11. The tonneau cover system of claim 1 , wherein the plurality of sections comprises a plurality of rigid panels.

12. The tonneau cover system of claim 1 , wherein the cooperating locking elements comprises a first pair of cooperating locking elements positioned adjacent a first lateral side of the tonneau cover and a second pair of cooperating locking elements positioned adjacent a second, opposite lateral side of the tonneau cover.

13. The tonneau cover system of claim 12 , further comprising an actuator coupling the pairs of cooperating locking elements together, and wherein actuation of the actuator simultaneously unlocks both the first and second pairs of cooperating locking elements.

14. The tonneau cover system of claim 13 , wherein the actuator includes a grasping handle adjacent the first lateral side of the tonneau cover, which first lateral side is positionable adjacent a driver's side of the truck.

15. The tonneau cover system of claim 13 , wherein the actuator comprises an cable extending between the first and second pairs of cooperating locking elements.

16. The tonneau cover system of claim 13 , wherein the actuator includes a grasping handle adjacent the first lateral side of the tonneau cover, which first lateral side is positionable adjacent a driver's side of the truck and wherein the grasping handle comprises a flexible tether.

17. The tonneau cover system of claim 6 , wherein the latch comprises a latch assembly including a pivoting latch and an independently pivoting actuator, wherein each of the pivoting latch and pivoting actuator is biased by a spring.

18. The tonneau cover system of claim 13 , wherein the actuator comprises a rigid elongate member extending between the first and second pairs of cooperating locking elements.

19. The tonneau cover system of claim 18 , wherein the actuator includes a grasping handle adjacent the first lateral side of the tonneau cover, which first lateral side is positionable adjacent a driver's side of the truck and the grasping handle comprises an extension of the rigid elongate member.

20. The tonneau cover system of claim 6 , wherein the latch comprises a hook member having a relatively long support arm and the striker comprises a hook member having a relatively short support arm.

21. The tonneau cover system of claim 1 , wherein a U-shaped member carries a first of each pair of cooperating locking elements.

22. The tonneau cover system of claim 21 , wherein a pair of brackets slidably couple the U-shaped member to the tonneau cover.

23. The tonneau cover system of claim 22 , further comprising a biasing member between the U-shaped member and at least one of the brackets to bias the first locking element of each pair of cooperating locking elements toward a locked position.

24. The tonneau cover system of claim 22 , wherein at least one of the brackets engages the U-shaped member to prevent rotational movement of the U-shaped member relative to the brackets.

25. The tonneau cover system of claim 1 , wherein each pair of cooperating locking elements comprises a pair of hook members.

26. The tonneau cover system of claim 1 , further comprising at least one biasing member biasing a first of each pair of cooperating locking elements toward a locking position, and wherein engagement of each pair of cooperating locking elements with each other initially counteracts the biasing member, and thereafter the biasing member moves each pair of cooperating locking elements into a lock position in which each pair of cooperating locking elements are locked with each other.
