摘要： The tilting trailer hitch (10) includes a compressible main support assembly (22) having a hitch coupler (24) and a hitching mechanism (26) attached thereto. The hitch coupler (24) is configured to connect a towing connector (92) to a towing vehicle (94) and the hitching mechanism (26) is configured to couple with a trailer (12). An actuator (28) is pivotally connected to the main support assembly (22) in response to trailer loading and is operable to rotate part of the main support assembly (22), thereby raising or lowering the hitching mechanism (26) along a generally arcuate path (116). When the hitching mechanism (26) is in the raised position, a loading end (20) of the trailer (12) is lowered to assist in loading the trailer (12).

摘要： A means for attaching a safety chain to a retractable ball or kingpin hitch is described. The means includes a metal face plate with an aperture therein. A first and second ring are coupled together while one or both is within the aperture such that both rings cannot simultaneously be removed from said aperture. The rings are size so that each has one large dimension that prevents the rings from passing completely through the aperture.

摘要： A tow hitch alignment apparatus having a pair of light sources that emit different colored light beams. The light sources are positioned such that, when the trailer hitch components are in proper position for engagement, both light beams intersect at the target location and emit a the third colored light, which indicates to the driver that the tow vehicle is in the proper position for coupling with the trailer. In an alternate embodiment, the tow vehicle has a horizontal sensor plate embedded with photoelectric cells adjacent the tow ball which detects the approach of the tow hitch from the trailer. A laser emitter is placed adjacent the trailer hitch and directed at a pre-focused position. As the tow ball approaches the hitch, laser light from the emitter strikes various photoelectric cells on the sensor plate, which is in connection with a display within the driver's compartment. The display provides information and guides the driver regarding the tow vehicle's path towards the trailer hitch.

摘要： 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.

摘要： A trailer hitch guide system comprising a trailer hitch having an inboard end coupled to a truck and having an outboard end with an upstanding ball. The trailer has a central extent for receiving a boat and an inboard end with an associated coupling component adapted to receive the ball and with an associated locking component. An attachment assembly interfacing between the ball and guide assists the driver of a truck in positioning the ball into position with respect to the guide. The assembly includes a rod with an upstanding vertical section and with a flag marker at the top thereof and a C-shaped section adjacent to the bottom thereof. A short vertical section at the bottom of the attachment assembly is coupled at its central extent to the bottom of the rod and has a contact plate therebeneath and an associated sphere thereabove. The sphere has a cylindrical aperture extending upwardly from the bottom of the sphere with a coil spring within the ball. A washer is coupled to the upper end of the vertical section and has a nut with exterior threads securing the washer and spring within the aperture.
