Abstract

A trailer hitch-mounted utility carrier for vehicles includes a carrier member having an upper wall to which vehicle accessories can be attached and a lower wall which is slotted to receive a "ball" type trailer hitch. In one embodiment, a clamping member pivotally connected to the carrier member is pivotable from a nonclamping position in which the carrier can be removed from the hitch to a clamping position in which the clamping member engages the ball to force a lower portion of the carrier into a clamped position between the ball and an underlying carrier support surface. In a second embodiment, turnbuckles exert a force between rear portions of the carrier member and underlying support to clamp a forward portion of the carrier into a clamped position between the ball and another portion of the support.

Claims

1. A utility carrier for attachment to a trailer hitch of a vehicle in which the hitch includes a hitch ball and an underlying support for the carrier, said carrier comprising:

a carrier member including an upper wall for attaching and supporting a load, and a slotted lower wall for receiving a neck portion of the hitch ball; and

force-applying means cooperable with said carrier member for selectively applying a clamping force to clamp a portion of said carrier member between said ball and said underlying support to secure said carrier member to the vehicle.

2. An apparatus according to claim 1 wherein said force-applying means includes a clamping member pivoted to said carrier member for selectively applying a clamping force against one portion of said ball to force said portion of said carrier member against an opposing portion of said ball.

3. An apparatus according to claim 1 wherein said force-applying means includes a clamping means operable to apply a clamping force against one portion of said hitch ball to draw said slotted lower wall against an opposing portion of said ball and thereby clamp said lower wall between said ball and said underlying support.

4. An apparatus according to claim 2 wherein said clamping member is pivoted to said carrier member for pivoting movement about an axis offset on one side of the center of said hitch ball and is operable upon movement about said axis to engage a portion of said ball on the opposite side of said center.

5. An apparatus according to claim 1 including antirotation means cooperative with said carrier member for restraining said carrier member against rotation on said underlying support about said ball.

6. An apparatus according to claim 2 including clamp operating means connected to said clamping member for pivoting said clamping means from a nonclamping position in which said lower wall is free to move relative to said hitch ball to a clamping position.

7. An apparatus according to claim 2 wherein said clamping member includes a force adjustment means for varying the magnitude of the clamping force applied to said carrier member.

8. An apparatus according claim 4 wherein said force-applying means includes a yoke member mounting said clamping member and pivoting said clamping member to said carrier member.

9. An apparatus according to claim 1 wherein said force-applying means includes extensible means operable to exert a force between said carrier member and said underlying support.

10. An apparatus according to claim 1 wherein said force-applying means includes means for applying a force between a first portion of said carrier member and one portion of the hitch to clamp a second portion of said carrier member in compression between said hitch ball and another portion of said hitch.

11. An apparatus according to claim 10 wherein said force-applying means applies said force to said hitch ball.

12. An apparatus according to claim 10 wherein said force-applying means applies said force to said underlying support.
