Abstract

The present application describes a gooseneck coupler assembly that may include a gooseneck trailer pivot, an extension arm, and a pivot retention mechanism having a ball socket. The ball socket may engage with a hitch ball located on a towing vehicle. The gooseneck trailer pivot may be mounted on a towed vehicle or trailer and be capable of pivoting about a vertical axis relative to the trailer. During engagement, the ball socket and the extension arm may provide tilt capability but thereby prevent any rotational movement relative to the hitch ball. However, the gooseneck coupler assembly may still be able to tilt fore-and-aft or side-to-side relative to the hitch ball. Therefore, the only pivotal movement relative to a vertical axis would be permitted at the gooseneck trailer pivot.

First claim

Having thus described the invention, we claim:

1. A coupler assembly comprising:
a trailer pivot capable of engagement with a towed vehicle;
an extension arm attached to the trailer pivot;
a vehicle engagement member capable of selectively engaging a hitch ball mounting aperture of a towing vehicle;
an engaging device secured to the extension arm and attached to the vehicle engagement member; and
a pivot retention member engaged with the engaging device generally preventing rotation of the towing vehicle relative to the extension arm.

2. The coupler assembly of claim 1 , wherein the trailer pivot includes a generally vertical axis whereby the towed vehicle may rotate relative to the vertical axis.

3. The coupler assembly of claim 2 , wherein the towed vehicle is capable of tilting relative to towing vehicle at the vehicle engagement member.

4. The coupler assembly of claim 3 , wherein the towed vehicle is capable of tilting fore and aft relative to the vertical axis at the vehicle engagement member.

5. The coupler assembly of claim 1 , wherein the vehicle engagement member includes a mounting body shaped and sized to be secured to the hitch ball mounting aperture of the towing vehicle.

6. The coupler assembly of claim 5 , wherein the engaging device includes a mounting block and a generally U-shaped bracket attached to the mounting body.

7. The coupler assembly of claim 6 , wherein the pivot retention member includes a mounting pin attached to the generally U-shaped bracket and engageable with the mounting block generally preventing rotation of the towing vehicle relative to the extension arm.

8. The coupler assembly of claim 7 , wherein the mounting pin prevents rotation about a first vertical axis at the mounting body.

9. The coupler assembly of claim 8 , wherein the trailer pivot is capable of rotation about a second vertical axis.

10. The coupler assembly of claim 1 , wherein the vehicle engagement member includes a socket attached to the extension arm and a hitch ball engaged with the socket and attached to the hitch ball mounting aperture of the towing vehicle.

11. The coupler assembly of claim 10 , wherein the engaging device includes a retention arm attached to the socket.

12. The coupler assembly of claim 11 , wherein the pivot retention member includes a support plate attached to the towing vehicle.

13. The coupler assembly of claim 12 , wherein the retention arm is generally aligned with a center of the hitch ball.

14. The coupler assembly of claim 13 , wherein the retention arm is capable of engaging the support plate.

15. The coupler assembly of claim 14 , wherein the support plate includes a retention pocket capable of engaging the retention arm.

16. A coupler assembly comprising:
a trailer pivot capable of engagement with a towed vehicle;
an extension arm attached to the trailer pivot;
a vehicle engagement member capable of being mounted to a hitch ball mounting aperture of a towing vehicle;
an engaging device secured to the extension arm and attached to the vehicle engagement member;
a first pivot retention member engaged with the engaging member generally preventing rotation of the towing vehicle relative to the extension arm; and
a second pivot retention member attached to the vehicle engagement member and capable of engaging the towing vehicle generally preventing rotation of the towing vehicle relative to the extension arm.

17. The coupler assembly of claim 16 , wherein the vehicle engagement member includes a platform and the second pivot retention member includes a pin capable of engaging the towing vehicle.

18. The coupler assembly of claim 17 , wherein the vehicle engagement member includes a socket attached to the extension arm and a hitch ball attached to the platform and engaged with the socket.

19. The coupler assembly of claim 17 , wherein the vehicle engagement member includes a mounting body attached to the platform.
