Hitch device
Described herein are improved devices for rotatably-coupled trailer hitch assemblies. A converter device can be used to convert the front arm of a trailer into a configuration that can be rotatably attached to a pivoting hitch member or coupler arm.
1 . A device for adapting an elongate arm for use with a pivoting hitch assembly, comprising:
a first shaft structures defining a first shaft configured to receive a pivot pin of the pivoting hitch assembly;
a second shaft structure defining a second shaft configured to receive a lock pin of the pivoting hitch assembly;
a connecting member connecting the first shaft structure and the second shaft structure, wherein the connecting wall, first shaft structure, and second shaft structure define a space adapted to receive the end of the elongate arm.
2 . The device of claim 1 , wherein the elongate arm comprises a coupler arm of the pivoting hitch assembly.
3 . The device of claim 1 , wherein the elongate arm comprises a front arm of a trailer.
4 . The device of claim 1 , wherein the space is substantially rectangular.
5 . The device of claim 1 , wherein the first and second shaft structures a barrel-shaped.
6 . The device of claim 1 , wherein the first and second shaft structures are elongated and taper in width moving away from the connecting member.
7 . The device of claim 1 , wherein the connecting member comprises a rectangular wall.
8 . The device of claim 1 , wherein the space has a width that is slightly larger than a width of the elongate arm.
9 . A pivoting hitch assembly, comprising:
a first elongate arm;
an adapter device attached to the first elongate arm, the adapter device comprising a first shaft member connected to a second shaft member, the first shaft member defining a first shaft and the second shaft member defining a second shaft, the adapter device defining a space between the first and second shaft members in which an end of the first elongate arm is positioned;
a second elongate arm;
at least one plate attached to the second elongate arm, the plate defining a first aperture aligned with the first shaft and a second aperture aligned with the second shaft;
a pivot pin positioned through the first shaft and the first aperture, the pivot pin defining an axis for relative rotational movement between the first and second elongate arms.
10 . The assembly of claim 9 , wherein the first elongate arm comprises a front arm of a trailer and the second elongate arm comprises a coupler arm for coupling the trailer to a towing vehicle, the second elongate arm being rotatable relative to the first elongate arm about the axis.
11 . The assembly of claim 9 , wherein the second elongate arm comprises a front arm of a trailer and the first elongate arm comprises a coupler arm for coupling the trailer to a towing vehicle, the first elongate arm being rotatable relative to the second elongate arm about the axis.
12 . The assembly of claim 9 , wherein the adapter device includes a connector wall connecting the first and second shaft members, the first and second shaft members positioned on opposed ends of the connector wall.
13 . The assembly of claim 9 , wherein the space has a size and shape that correspond to a size and shape of the first elongate arm.
14 . The device of claim 9 , wherein the first and second shaft structures a barrel-shaped.
15 . The device of claim 9 , wherein the first and second shaft structures are elongated and taper in width moving away from the connecting member.
