  • Patent number: 9701169
    Abstract: A unique adjustable trailer-locking system comprises a locking ball, a lock, a locking pin, a key, and first, second, third, and fourth size-adjusting caps. The locking ball has a through hole. Each of the first, second, third, and fourth size-adjusting caps has a dome shape and a hollow shaft attached to its center. Each of the hollow shafts can be inserted into the through hole or another hollow shaft to assemble, disassemble, and switch the size of the locking ball, to fit inside a hitch-ball receiver of one of standardized sizes to eliminate all the gaps therebetween, to prevent a crowbar from being inserted therebetween to pry the locking ball off. The locking pin is for being inserted through a hitch-ball-receiver lever and through the lock. The key is for turning the lock to secure the locking pin and the hitch-ball-receiver lever.

  • Patent number: 8286985
    Abstract: An architecture is presented that provides a double hinged tow hitch. The tow hitch is attached to a tow vehicle and allows full traction to the ground and complete control of steering. The tow hitch comprises two hinges secured together by a pin positioned at an upper portion of the hinges and a pin positioned at a lower portion of the hinges. The pins secure the hinges together and allow the hinges to flex in two positions. Additionally, the tow hitch comprises springs positioned on either side of the hinges and rubber positioned between the hinges to act as a shock absorber. When pressure is applied to the tow hitch, the springs will collapse into either the upper or lower portions of the hinges, causing the hinges to flex in two positions and pressing against the rubber between the hinges, thus acting as a suspension system for the tow hitch.

  • Patent number: 7815210
    Abstract: The present trailer hitch assembly addresses the problem of lost tongue weight support and towing capacity when a person adds an extension to a trailer hitch for adding a slide-in camper to a truck or for moving a trailer back a little to increase the turning radius. Generally, when such an extension is utilized, the towing capacity of the vehicle to which the extension is attached is downgraded, due to the lengthening of the overall trailer hitch assembly and lack of structural support. Disclosed herein is a trailer hitch assembly that addresses this problem by providing extra structural support to boost this lack of structural support.

  • Patent number: 5918896
    Abstract: A self locking chain device for locking a chain to a vehicle comprises an elongated cross bar having an upwardly extending arm attached to each end thereof. Each arm comprises first and second arbors which define a receiving slot for receiving a first interior link of a chain and configured in such a manner to enable two adjacent contiguous links to lock the interior link therein. Both first and second arbors are provided with cusps or projections for limiting passage of the chain link to and from the receiving slot. The first arbor also is provided with a concavity. A second contiguous or selected link, serving as a locking link, is slid over and down the first arbor and to the concavity, thereby double locking the first interior link since the opening between the cusps or projections is less than the combined diameter of the interior link and locking link.

  • Patent number: 5906387
    Abstract: A retractable ball or kingpin hitch is provided for the load bed of a vehicle. The retractable ball or kingpin hitch is provided with a movable pin mounted in a wall of the hitch for locking the ball or kingpin in an upright operational position. The locking feature assures that the retractable ball or kingpin will not be able to partially retract thereby compromising the effectiveness of the hitch and coupling when hauling a trailer.

  • Patent number: 5893575
    Abstract: A hitch assembly is provided with a hitch mount and a safety chain connector, both of which adjust 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 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.

  • Patent number: 5788258
    Abstract: A folding ball hitch having a recessed safety chain latching mechanism is of the type normally mounted in the bed of a pickup truck. The ball is foldable from an upright or active position to a down or stowed position in which the ball does not interfere with the usage of the bed when the truck is not towing a trailer. To accommodate the safety chains of a trailer, the present invention provides a sliding rod mounted below the mounting plate of the hitch. Chain link sized slots are formed in the mounting plate. The end links of the safety chains can be inserted into the slots and the rod can be slid from one side to the other to securely lock the chains in respective slots. The rod is biased toward a latching position wherein the rod can be manually translated to open the slot for allowing insertion of a link of the safety chain, following which the rod can be returned to its center position in which the link is secured and any chain forces are transferred by the rod directly to the mounting structure.

  • Patent number: 5732967
    Abstract: 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.

  • Patent number: 5465991
    Abstract: 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.
