The hitch mount is configured for retractable extension from a hitch base plate, providing a seat for a matching trailer mount. The safety chain connector is configured to selectively provide a seat for a trailer-connected safety chain. The hitch base plate attaches to the towing vehicle body, defining a support surface which is contoured substantially similar to the body contour of the towing vehicle. The hitch mount and safety chain connector are adjustable such that the hitch assembly may be conformed generally to the body contour of the towing vehicle, thus minimizing any interference with the vehicle's use.Type: GrantFiled: July 1, 1996Date of Patent: April 14, 1998Inventor: Kenneth M. Larkin

Patent number: 5732967Abstract: A safety chain for securing a towed vehicle to a towing vehicle and which has a safety basket for limiting downward movement of a tongue of the towed vehicle relative to a hitch of the towing vehicle to prevent the tongue from contacting the roadway. The chain is attached to at least one of the vehicles by a latch that has a shackle for engagement with a mount of the vehicle and a catch carried by the shackle that can be spring biased toward its latched position and which is movable to a position disposed from its latched position to unlatch the latch. Preferably, the catch can be retained in the latched position by a retainer that engages the catch and shackle. Preferably, to secure the latch to a vehicle to deter theft of the chain, the retainer can be a lock. To secure the safety chain to the tongue to prevent theft of the tongue and preferably the towed vehicle, a securing chain and a locking chain are wrapped around the tongue to prevent withdrawal of the tongue free of the chains.Type: GrantFiled: October 19, 1995Date of Patent: March 31, 1998Assignees: Andrew G. Behling, Susan J. CorcoranInventor: Andrew G. Behling

Patent number: 5571270Abstract: A hitch assembly is proved with a retractable hitch mount and a retractable safety chain connector, both of which retract to provide a hitch assembly which conforms substantially to the contour of the towing vehicle body when the hitch assembly is not in use. The hitch mount is configured for retractable extension from a hitch base plate, providing a seat for a matching trailer mount. The safety chain connector is configured for retractable extension from the base plate, providing a seat for a trailer-connected safety chain. The hitch base plate attaches to the towing vehicle body, defining a support surface which is contoured substantially similar to the body contour of the towing vehicle. When the hitch mount and safety chain connector are retracted, the hitch assembly conforms generally to the body contour of the towing vehicle, minimizing any interference with the vehicle's use.Type: GrantFiled: May 15, 1995Date of Patent: November 5, 1996Inventor: Kenneth M.

Patent number: 5562298Abstract: A weight distributing hitch for towing a trailer includes a hitch bar, a ball mount head and spring bars for distributing the weight of the trailer relative to a towing vehicle. The spring bars include mounting trunnions and the ball mount head includes cooperating sockets for receiving those mounting trunnions. The spring bars are installed in the ball mount head by inserting a first end of the mounting trunnion in a first cooperating mounting socket, passing a second end of the mounting trunnion through a channel communicating with a second cooperating mounting socket and engaging the second end of the trunnion in the second cooperating mounting socket.Type: GrantFiled: October 7, 1994Date of Patent: October 8, 1996Assignee: Reese Products, Inc.Inventors: John J. Kass, Philip K. Hoopes

Patent number: 5465991Abstract: A weight distributing hitch for towing a trailer behind a vehicle includes a hitch bar for mounting to the vehicle and a ball mount head for mounting on the hitch bar at a selected tilt angle. A pair of spring bars are mounted to the ball mount head. These spring bars distribute the weight of the trailer relative to the vehicle. Each spring bar is substantially L-shaped and includes a turned groove at a proximal end received in a cooperating aperture in the ball mount head. A retainer of spring steel engages in the grooves to hold the spring bars in position. The relative tilt angle of the ball mount head is adjusted by means of an eccentric angle adjusting element in the form of a washer. This washer is fixed to one of the ball mount head or hitch bar and includes a cam surface for engaging the other of the two elements.Type: GrantFiled: December 13, 1994Date of Patent: November 14, 1995Assignee: Reese Products, Inc.Inventors: John J.
