Cargo carrier assembly with hinge mechanism

1. A cargo carrier assembly comprising:

a draw bar;

a carrier member to support cargo thereon;

a hinge mechanism attached to the draw bar that includes a linkage device, the linkage device includes a first plate spaced from a second plate such that the carrier member is pivotally secured between the first plate and the second plate;

a guide aperture that includes a contoured path to receive a guide member attached to the carrier member, the guide aperture includes a straight position groove, an unlock position groove, a drop position groove, and an upward position groove;

wherein the carrier member is configured to be selectively pivoted between a straight position as the guide member is positioned in the straight position groove, an unlock position as the guide member is positioned in the unlock position groove, an up position as the guide member is positioned in the upward position groove, and a drop position as the guide member is positioned in the drop position groove.

2. The cargo carrier assembly of claim 1 , wherein the hinge mechanism allows the carrier member to be selectively pivoted between the straight positon and the unlock position by translating the carrier member along a first direction.

3. The cargo carrier assembly of claim 1 further comprising at least one pivot arm that is rotatably attached to the draw bar at a first pivot point and is rotatably attached to the carrier member at a second pivot point.

4. The cargo carrier assembly of claim 3 wherein the at least one pivot arm includes a contoured surface and the linkage device includes a contoured surface wherein the contoured surface of the pivot arm nests with the contoured surface of the linkage device as the carrier member is pivoted.

5. The cargo carrier assembly of claim 4 , wherein the contoured surface of the pivot arm and the contoured surface of the linkage device provide a pivotal range of motion that allows for stable movement during pivoting motion.

6. The cargo carrier assembly of claim 1 wherein the contoured path includes at least one guide aperture.

7. The cargo carrier assembly of claim 6 , wherein the guide aperture includes a straight position groove, a drop position groove, a rotational groove, an unlock position groove, and an upward position groove wherein the grooves are arranged in a generally continuous shape.

8. The cargo carrier assembly of claim 7 , wherein the guide aperture further comprises a protrusion positioned between the straight position groove and the unlock position groove wherein the guide member selectively overcomes the protrusion to pivot between the straight position groove and the unlock position groove.

9. The cargo carrier assembly of claim 1 , wherein the hinge mechanism includes a locking feature to assist with locking the carrier member in a position relative to the draw bar.

10. The cargo carrier assembly of claim 9 , wherein the locking feature is a pin selectively positioned in at least one aperture within the hinge mechanism.

11. The cargo carrier assembly of claim 1 wherein the draw bar is attachable to a hitch receiver of a vehicle.

12. The cargo carrier assembly of claim 1 , wherein the cargo is a bike carrier assembly.

13. The cargo carrier assembly of claim 12 , further comprising a support arm to support additional bike carriers in a generally scalable arrangement such that a plurality of bike carriers can extend from the hinge mechanism and pivot between the upward position, the straight position, and the lower position.

14. A hinge mechanism for attaching a cargo accessory to a vehicle, the hinge mechanism comprising:

a linkage device selectively attachable to a vehicle,

a carrier member having a draw bar pivotally attached to the linkage device, wherein the cargo accessory carrying member is pivotable between a straight position, an unlock position, an upward position, and a drop position;

at least one pivot arm that is rotatably attached to the draw bar at a first pivot point and is rotatably attached to the carrier member at a second pivot point wherein the at least one pivot arm includes a contoured surface and the linkage device includes a contoured surface wherein the contoured surface of the pivot arm nests with the contoured surface of the linkage device as the carrier member is pivoted;

wherein the contoured surface of the pivot arm and the contoured surface of the linkage device provide a pivotal range of motion that allows for stable movement during pivoting motion.

15. The hinge mechanism of claim 14 , wherein the wherein the carrier member includes a guide member and the linkage device includes guide apertures wherein the guide member may be selectively positioned within the guide apertures permitting pivoting of the cargo accessory carrying member relative to the linkage device.

16. The hinge mechanism of claim 14 , wherein the guide aperture includes a straight position groove, a drop position groove, a rotational groove, an unlock position groove, and an upward position groove wherein the grooves are arranged in a generally continuous shape.

17. The hinge mechanism of claim 14 , wherein the carrier member is a platform type bike carrier assembly.

18. The hinge mechanism of claim 17 , wherein the guide aperture further comprises a notch to receive a portion of the guide member that is positioned between the straight position groove and the unlock position groove to allow the guide member and carrier member to be maintained in the straight position.

19. The hinge mechanism of claim 14 further comprising a locking member to toggle the hinge mechanism between a locked configuration and an unlocked configuration.
