  • Patent number: 7806424
    Abstract: A fifth wheel hitch for towing a trailer behind a motor vehicle is adjustable between a forward position and a rearward position. The fifth wheel hitch includes a base assembly for mounting to the motor vehicle, head assembly for engaging the trailer and at least one pivoting arm coupled between the base assembly and the head assembly. The head assembly moves in an arcuate path between the forward position and the rearward position as the pivoting arm articulates relative to the base assembly. Once positioned in the forward or rearward position, the head assembly is locked relative to the base assembly so as to prevent further movement.

  • Publication number: 20070257469
    Abstract: A hitch is disclosed for vertical and horizontal loading of a trailer latching device. The hitch includes a locking extension positionable to interface with a lesser diameter portion of a coupling member to prevent vertical movement of the coupling member. The hitch also includes a cup comprising an at least partially arcuate sidewall positionable to interface with a greater diameter portion of the coupling member to prevent horizontal coupling member movement. Linkage coordinates relative movement of the locking extension and the cup such that the coupling member is receivable into lockable engagement with the hitch upon either vertical or horizontal movement of the coupling member relative to the hitch.
