Covering structure having automatic coupling system
View Patent ↗A tonneau system for a cargo box of a vehicle having a support frame connectable to the cargo box. A cover spans the support frame and is positionable between a tensioned position and an untensioned position. A pivot block is mounted to the support frame, while the cover is coupled to a front bracket member. The front bracket member carries the cover and pivotally engages the pivot block such that the front bracket member rotates between a raised position and a lowered position. The front bracket member can be automatically locked in the lowered position. The front bracket member can also be unlocked and rotated to a raised position. In the raised position, bracket member may be removed from the support frame and positioned to provide temporary access to the cargo box without unsecuring the remaining portions of the tonneau cover. A bow member couples the cover along a cross vehicle direction. The bow member or other member can operate to tension the cover in the cross vehicle direction.
1. A method of releasably securing a cover to a vehicle, said method comprising:
providing a cover spanning at least a portion of a frame, said frame having a retaining member and a pivot block;
coupling a first end of said cover to a first bracket member;
engaging and rotating said first bracket member relative to said frame from a first position to a second position, wherein at said second position, said first bracket member applies a tensioning force to said cover to bias said cover in a first direction and causes a bow member of said cover to engage said retaining member of said frame;
coupling a second end of said cover to a second bracket member;
engaging and rotating said second bracket member relative to said pivot block from a first position to a second position; and
releasably securing said second bracket member at said second position relative to said pivot block.
2. The method according to claim 1 wherein said releasably securing said second bracket member at said second position relative to said pivot block comprises:
providing a locking pawl system rotatably coupled to said pivot block, said locking pawl system positionable between a retracted position and an extended position;
urging said locking pawl system into said retracted position while said engaging and rotating said second bracket member relative to said pivot block from said first position to said second position; and
positioning said locking pawl system in said extended position to engage and retain said second bracket member relative to said pivot block.
3. The method of claim 2 wherein said urging said locking pawl system into said retracted position comprises pulling on a latch strap coupled to said locking pawl system.
4. The method of claim 1 , further comprising:
unsecuring said second bracket member; and
positioning said second bracket member at a retracted position, wherein at said retracted position a portion of the vehicle beneath said cover is accessible.
5. The method of claim 4 , wherein said unsecuring said second bracket member occurs after said engaging and rotating said first bracket member relative to said frame from said first position to said second position.
6. The method of claim 1 , wherein said vehicle defines a forward end and a rear end, wherein said engaging and rotating said first bracket member comprises engaging and rotating said first bracket member adjacent said rear end of said vehicle, and wherein said engaging and rotating said second bracket member comprises engaging and rotating said second bracket member adjacent said forward end of said vehicle.
