Abstract

A cargo support system for a motor vehicle includes a `U`-shaped bar rotatable from a stowed position to an operable position. The `U`-shaped bar preferably has a pair of end members rotatably coupled to the dropgate of the motor vehicle and a cross member interconnecting the pair of end members. A locking hinge mechanism is operable to secure the U-shaped bar in either the stowed or operable position.

Claims

1. A cargo support system for a motor vehicle, comprising:

a cargo bed having a bed floor, a back wall, and first and second sidewalls;

a dropgate rotatably coupled to said cargo bed and being rotatable from a closed position to an open position, said dropgate having a support surface formed therein; and

a `U`-shaped bar having a pair of end members, a pair of side members extending from said pair of end members and a cross member interconnecting said pair of side members, said pair of end members being operably coupled to said dropgate for relative pivotal and lateral movement;

said `U`-shaped bar being releasably securable in a stowed position wherein said `U`-shaped bar is generally co-planar with said dropgate and in an operable position

wherein said `U`-shaped bar is generally perpendicular to said dropgate and laterally displaced from said stowed position such that at least one of said pair of side members engages said support surface formed in said dropgate.

2. The cargo support system of claim 1, further including at least one roller operably supported on said cross member of said `U`-shaped bar.

3. The cargo support system of claim 1, wherein said dropgate includes a latch grasping a portion of said cross member when said `U`-shaped bar is in said stowed position.

4. The cargo support system of claim 1 further comprising first and second slat pockets respectively formed in said first and second sidewalls and a supporting slat having ends received in said first and second slat pockets, said supporting slat and said cross member providing a supporting surface which is substantially parallel with and offset above said bed floor.

5. The pickup truck of claim 1 further comprising:

a plate secured to said dropgate and providing a pin-receiving bore;

at least one of said end members having an aperture formed therethrough which aligns with said pin-receiving bore when said `U`-shaped bar is in said operable position; and

a lock pin received in said pin-receiving bore and said aperture for releasably securing said `U`-shaped bar in said operable position.

6. The pickup truck of claim 5 further comprising at least one of said end members having a second aperture formed therethrough which aligns with said pin-receiving bore when said `U`-shaped bar is in said stowed position, said lock pin received in said pin-receiving bore and said second aperture for releasably securing said `U`-shaped bar in said stowed position.

7. A cargo support system for a vehicle of the type having first and second sidewalls and a bed, the dropgate cargo support system comprising:

a dropgate articulable from an open position to a closed position and having a support surface formed therein; and

a `U`-shaped bar having a pair of end members, a pair of side members extending from said pair of end members and a cross member interconnecting said pair of side members, said pair of end members being operably coupled to said dropgate for relative pivotal and lateral movement;

said `U`-shaped bar being releasably securable in a stowed position wherein said `U`-shaped bar is generally co-planar with said dropgate and in an operable position wherein said `U`-shaped bar is generally perpendicular to said dropgate and laterally displaced from said stowed position such that at least one of said pair of side members engages said support surface formed in said dropgate.

8. The cargo support system for a vehicle of claim 7, further including at least one roller operably supported to said cross member of said `U`-shaped bar.

9. The cargo support system of claim 7, wherein said dropgate includes a latch grasping a portion of said cross member when said `U`-shaped bar is in said stowed position.

10. The cargo support system of claim 7 further comprising a hinge plate disposed over said pair of end members and secured to said dropgate for operably coupling said `U`-shaped bar to said dropgate.

11. The cargo support system of claim 10 further comprising a lower hinge plate disposed beneath said pair of end members and secured to said dropgate for operably coupling said `U`-shaped bar to said dropgate.

12. The cargo support system of claim 11 further comprising a bushing placed over said pair of end members and interdisposed between said hinge plate and said lower hinge plate.

13. The cargo support system of claim 10 wherein said hinge plate defines a pin-receiving bore and wherein at least one of said end members has an aperture formed therethrough which aligns with said pin-receiving bore when said `U`-shaped bar is in said operable position and receives a lock pin for releasably securing said `U`-shaped bar in said operable position.

14. The cargo support system of claim 13 wherein at least one of said end members has a second aperture formed therethrough which aligns with said pin-receiving bore when said `U`-shaped bar is in said stowed position and receives said lock pin for releasably securing said `U`-shaped bar in said stowed position.

15. The cargo support system of claim 7 further comprising a pair of end caps, each of said pair of end caps disposed in a free end of each of said pair of end members.

16. A pickup truck comprising:

a body including a bed, first and second laterally spaced apart sidewalls and a dropgate;

a cargo support system including a `U`-shaped bar having a pair of end members, a pair of side members extending from said pair of end members and a cross member interconnecting said pair of side members, said pair of end members being operably coupled to said dropgate for pivotal and lateral movement such that said `U`-shaped bar is releasably securable in a stowed position wherein said `U`-shaped bar is generally co-planar with said dropgate and in an operable position wherein said `U`-shaped bar is generally perpendicular to said dropgate and laterally displaced from said stowed position and at least one of said pair of side members engages said support surface formed in said dropgate;

at least one roller operably supported on said cross member of said `U`-shaped bar;

a first locking mechanism operably disposed between said dropgate and said `U`-shaped bar to lock said `U`-shaped bar in said stowed position; and

a second locking mechanism operably disposed between said dropgate and said `U`-shaped bar to lock said `U`-shaped bar in said operable position.

17. The pickup truck of claim 16 wherein said first locking mechanism comprises a latch grasping a portion of said cross member when said `U`-shaped bar is in said stowed position.

18. The pickup truck of claim 16 wherein said second locking mechanism comprises:

a plate secured to said dropgate and providing a pin-receiving bore;

at least one of said end members having an aperture formed therethrough which aligns with a pin-receiving bore when said `U`-shaped bar is in said operable position; and

a lock pin received in said pin-receiving bore and said aperture for fixing said `U`-shaped bar in said operable position.

19. The pickup truck of claim 18 further comprising at least one of said end members having a second aperture formed therethrough which aligns with said pin-receiving bore when said `U`-shaped bar is in said stowed position, said lock pin received in said pin-receiving bore and said second aperture for releasably securing said `U`-shaped bar in said stowed position.

20. The pickup truck of claim 16 further comprising first and second slat pockets respectively formed in said first and second laterally spaced apart sidewalls and a supporting slat having ends received in said first and second slat pockets, said supporting slat and said cross member providing a supporting surface which is substantially parallel with and offset above said bed.
