Abstract

A hitch apparatus includes a housing configured to be attached to a vehicle, a tow bar movably disposed within the housing, a hitch member assembly, and a fastener configured to removably secure the hitch member assembly to the height adjustment member at any of a plurality of selected elevations. The tow bar is movable relative to the housing between retracted and extended positions, and is pivotable relative to the housing when in an extended position. As such, a hitch member at the distal end of the tow bar has horizontal and vertical adjustment capabilities.

a fastener that is engagable with aligned apertures in the support members and height adjustment member side walls so as to removably secure the hitch member assembly to the height adjustment member at any of the plurality of elevations.

2. The hitch apparatus of claim 1, wherein the housing comprises a longitudinally extending forwardly opening cavity with a restricted opening, wherein the tow bar comprises a front portion and a rear portion connected by a medial portion, the rear portion having a width greater than the restricted opening such that the rear portion cannot be extended through the opening.

3. The hitch apparatus of claim 2, wherein the medial portion comprises outwardly diverging curvilinear edge portions that cooperate with the restricted opening such that an extent to which the tow bar can pivot relative to the housing progressively increases as the tow bar is progressively extended.

4. The hitch apparatus of claim 1, wherein the hitch member comprises a weight distribution apparatus having at least one member configured to be attached to a towed vehicle.

5. The hitch apparatus of claim 1, wherein the support member first and second portions are respective first and second elongated segments that are oriented transverse to each other.

6. The hitch apparatus of claim 5, wherein the first and second elongated segments are oriented substantially orthogonal to each other.

7. The hitch apparatus of claim 1, wherein the fastener comprises a pair of pins, each pin engagable with aligned apertures in the support members and height adjustment member side walls at a selected elevation.

8. The hitch apparatus of claim 1, wherein the height adjustment member comprises an elongated stiffening member attached to the rear wall thereof, wherein the stiffening member comprises a notch that matingly engages a corresponding notch in the tow bar distal end.

9. The hitch apparatus of claim 1, wherein the height adjustment member comprises a plate having opposing front and rear sides and rows of vertically spaced apertures formed therethrough, wherein the height adjustment member is configured to support a hitch member at a plurality of selected elevations.

10. The hitch apparatus of claim 9, further comprising:

a hitch member; and

a plurality of fasteners configured to removably secure the hitch member to the height adjustment member at any of the plurality of elevations.

11. The hitch apparatus of claim 1, further comprising a frame having an elongated base member with opposite end portions, and a pair of arms extending away from the base member end portions in side by side, spaced-apart relationship, wherein each arm includes a mounting bracket configured to be attached to a frame of a vehicle, and wherein the housing is secured to the frame base member.

12. The hitch apparatus of claim 1, further comprising a locking member operably secured to the housing that releasably engages the tow bar to maintain the tow bar in a retracted position.

13. The hitch apparatus of claim 12, wherein the tow bar has an opening formed therethrough, and wherein the locking member is retractably extendable through the opening to maintain the tow bar in a retracted position.

14. The hitch apparatus of claim 13, further comprising a biasing member that compressively biases the locking member toward the tow bar.

15. The hitch apparatus of claim 14, wherein the locking member engages a surface of the tow bar when the locking member is retracted from the opening and the tow bar is extended.

16. The hitch apparatus of claim 13, wherein the locking member comprises a handle that is configured to disengage the locking member from the tow bar in response to user activation.

17. The hitch apparatus of claim 1, wherein the hitch member is selected from the group consisting of a ball coupler, a pintle hook, a cushioned pintle hook, a swivel pintle hook, a lunette ring, and a clevis pin attachment.

18. A hitch apparatus, comprising:

a housing configured to be attached to a vehicle;

a tow bar movably disposed within the housing, wherein the tow bar is movable relative to the housing between retracted and extended positions, and is pivotable relative to the housing when in an extended position, and wherein a guide pin extends outwardly from a surface of a proximal end portion of the tow bar and is operably engaged with a slot in the housing to limit movement of the hitch assembly relative to the housing; and

an elongated height adjustment member attached to a distal end of the tow bar, wherein the height adjustment member is configured to support a hitch member at a plurality of elevations.

19. The hitch apparatus of claim 18, further comprising:

a hitch member assembly; and

a fastener configured to removably secure the hitch member assembly to the height adjustment member at any of a plurality of elevations.

20. The hitch apparatus of claim 19:

wherein the height adjustment member comprises a rear wall and opposing, elongated side walls extending outwardly from the rear wall in adjacent, spaced-apart relationship, wherein each side wall includes a plurality of vertically spaced apertures formed therethrough;

wherein the hitch member assembly comprises a base having opposite side portions, a hitch member secured to the base, and a pair of support members, wherein each support member has a first portion secured to a respective side of the base and a second portion that includes a pair of spaced-apart apertures formed therethrough; and

wherein the fastener is engagable with aligned apertures in the support members and height adjustment member side walls at selected elevations.

21. The hitch apparatus of claim 20, wherein the support member first and second portions are respective first and second elongated segments that are oriented transverse to each other.
