  • Pivoting trailer hitch
    Patent number: 12454159
    Abstract: A trailer coupling mechanism includes a first end, a second end, a height adjustment assembly, a first swivel assembly, and a second swivel assembly. The first end is adapted to couple to one of a trailer and a vehicle. The second end is adapted to couple to the other of the trailer and the vehicle. The height adjustment assembly is coupled between the first and second ends and is operative to adjust the relative height between the first and second ends. The first swivel assembly is coupled between the height adjustment assembly and the first end and facilitates rotation of the first end with respect to the height adjustment assembly about a first axis. The second swivel assembly is coupled between the second end and the height adjustment assembly and facilitates rotation of the height adjustment assembly with respect to the second end about a second axis parallel to the first axis.
