Abstract

A tonneau system for a cargo box of a vehicle including a support frame, a cover spanning the support frame; and a clamp. The support frame includes side rails having an inboard section and an outboard section, such that the outboard section is positioned adjacent to the top surface of the sidewall of the cargo box to aid in the supporting and positioning of the support frame. The clamp is capable of hanging from the support frame during installation to improve the ease thereof. The clamp also includes a pair of members being positionable in any one of a plurality of discrete positions for improved installation. A front rail adjustment mechanism permits the selective tensioning of the cover to maintain a predetermined load therein. While a front rail retaining mechanism is slidably coupled to the front rail member to prevent the front rail member from being inadvertently disengaged from the side rail members. A rear rail retaining mechanism is used to lock the rear rail member or unlock the rear rail member and urge the rear rail member upward.

Claims

1. A tonneau system for a cargo box of a vehicle, said cargo box having a sidewall, said sidewall has a top surface and an inside wall, said tonneau system comprising:

a support frame having a generally horizontal portion and a generally vertical portion downwardly extending from said generally horizontal portion from a position bisecting said generally horizontal portion into an inboard section and an outboard section, said outboard section being positionable adjacent the top surface of the sidewall, said generally vertical portion being positionable adjacent the inside wall of the sidewall;

a cover spanning said support frame; and

a seal positionable between said outboard section and the top surface of said sidewall.

2. The tonneau system according to claim 1 wherein said seal is a D-shaped seal.

3. The tonneau system according to claim 1, further comprising:

a seal positionable between said generally vertical portion and the inside wall of the sidewall.

4. The tonneau system according to claim 3 wherein said seal is a flat seal.

5. The tonneau system according to claim 1, further comprising:

a first hook-and-loop fastener coupled to said cover; and

a second hook-and-loop fastener coupled to said generally horizontal portion of said support frame, said second hook-and-loop fastener detachably engagable with said first hook-and-loop fastener.

6. The tonneau system according to claim 1 wherein said second hook-and-loop fastener is detachably engagable with said first hook-and-loop fastener during a rolling operation of said cover.

7. A tonneau system for a cargo box of a vehicle, said cargo box having a sidewall, said sidewall has a top surface and an inside wall, said tonneau system comprising:

a support frame having a generally horizontal portion and a generally vertical portion downwardly extending from said generally horizontal portion from a position bisecting said generally horizontal portion into an inboard section and an outboard section, said outboard section being positionable adjacent the top surface of the sidewall, said generally vertical portion being positionable adjacent the inside wall of the sidewall;

a cover spanning said support frame;

a first seal positionable between said outboard section and the top surface of said sidewall; and

a second seal positionable between said generally vertical portion and the inside wall of the sidewall.

8. The tonneau system according to claim 7 wherein said first seal is a D-shaped seal.

9. The tonneau system according to claim 7 wherein said second seal is a flat seal.

10. The tonneau system according to claim 7, further comprising:

a first hook-and-loop fastener coupled to said cover; and

a second hook-and-loop fastener coupled to said generally horizontal portion of said support frame, said second hook-and-loop fastener detachably engagable with said first hook-and-loop fastener.

11. The tonneau system according to claim 7 wherein said second hook-and-loop fastener is detachably engagable with said first hook-and-loop fastener during a rolling operation of said cover.
