US Classification:

254423, 2807631, 254424, 29428

Abstract:

A system for supporting a vehicle. The system may include a vehicle jack in mechanical communication with a jack foot and a striker plate. The jack foot is rotatable relative to the vehicle jack on a rotation axis disposed on the vehicle jack and perpendicular to a long axis of the vehicle jack. The jack foot includes a base at a distal end of the jack foot. The jack foot also includes a cam surface at least in part at a proximal end of the jack foot. The cam surface is aligned with the striker plate and interacts with the striker plate to rotate the jack foot in response to movement of the vehicle jack from a lowered position to a raised position.

International Classification:

B60D 1/36
B60D 1/167
B60D 1/48

Abstract:

A trailer hitch system for attaching a trailer to a tow vehicle, is disclosed having a shank attachable a trailer, the shank having a nose at a terminal end of the shank and a mid-shank extending in a substantially horizontal direction immediately adjacent to the nose, the nose and mid-shank being configured to be received in a receiver attachable to said tow vehicle. The shank also includes a vertical adjustment extending in a substantially vertical direction, a depth stop connected to the shank and configured to abut the receiver to limit a depth that the shank extends within the receiver. The mid-shank includes step reduction which decreases a cross-sectional area of the mid-shank immediately adjacent to the nose, and the nose is configured to reduce in cross-sectional area toward the terminal end of the shank. The shank also includes an alignment indicator connected to the shank, such that the alignment indicator to provide a visual indicator of the orientation of the shank.

International Classification:

B60D 1/28
B60D 1/06

Abstract:

An adjustable height trailer hitch may include a shank portion configured and adapted to be installed into a hitch receiver. The hitch may further include a drop bar extending downwardly from the shank portion. The drop bar may further include a plurality of pin receiving holes formed in the drop bar. The hitch may further include a ball support member having a locking pin disposed in a locking-pin bore and an actuator pin disposed in an actuator bore. The hitch may further include a locking ring disposed in an annular groove of a cylindrical sidewall of the actuator bore. The locking ring may prevent backout of the actuator pin.
