Abstract: A hitch ball assembly includes a towing ball having a mounting aperture and an annular race in communication with the mounting aperture. A post includes a base, an axial bore and a plurality of openings in communication with the axial bore. A ball bearing is received in each of these openings. A plunger is axially displaceable in the post between a first position allowing the towing ball to be removed from or attached to the post and a second position for securing the towing ball to the post while allowing the towing ball to turn on the post. A spring, received in the axial bore, engages an end of the plunger and biases the plunger to the first position.

Abstract: A alignment apparatus for assisting a driver in directing coupling engagement between a towing vehicle hitch and a trailer hitch. The apparatus includes a guide carried by the towing vehicle representing the position of the towing vehicle hitch for being visible to the driver. A target is carried by the trailer representing the position of the trailer hitch for being visible to the driver. The target has a pair of laterally spaced posts defining a target zone for receiving the guide to align the towing vehicle hitch with the trailer hitch for coupling engagement. A sensor is carried by the guide for determining whether the guide is within the target zone. An indicator is operatively associated with the sensor for indicating to the driver when the guide is within the target zone to alert the driver of alignment between the towing vehicle hitch and the trailer hitch for coupling engagement.

Abstract: A hitch extension apparatus for attaching an implement with a pto driven drive shaft having front and rear universal joints to a tractor drawbar. The apparatus comprises a first member adapted for attachment to the tractor drawbar by insertion of a drawbar pin through the drawbar such that the first member is fixed with respect to the drawbar. An extension member is pivotally attached to the first member about a horizontal pitch axis oriented perpendicular to the travel direction, and about a horizontal roll axis oriented parallel to the operating travel direction. The extension member defines a pivotal attachment location rearward of the draw pin hole adapted for pivotal attachment of the implement about a vertical yaw axis located equidistant from the front and rear universal joints when the drive shaft is connected to the tractor power take off. The pitch axis can be located forward of the yaw axis, and forward of the draw pin hole in order to reduce bending forces on the drawbar.

Abstract: The present invention is a system for hooking a trailer to a towing vehicle. The system has a winch attached to the trailer and a cable that wraps around the ball hitch and is attached to a plate on the trailer. By spacing the cable wide at the plate on the trailer and narrow at the ball of the hitch, the trailer is automatically adjusted to position the tongue of the trailer to center it on the ball hitch.

Abstract: A bumper assembly for a motor vehicle includes a bumper structure having a bumper beam adapted for attachment to a structure of a motor vehicle such as a frame or rails, or the like. A hitch is attached to the bumper beam, and a bumper cover conceals the bumper beam. The bumper cover has an opening for accessing the hitch and an access door for selectively concealing the hitch. The access door is mounted to the bumper structure such that the access door will be retained upon the bumper structure not only when the access door is concealing the hitch but also when the access door is open to allow an accessory such as a trailer to be coupled to the hitch.

Abstract: A receiver cover includes a stationary member that is configured to be secured to an end of a receiver for a trailer hitch. The receiver cover also includes a door which is hingedly connected to the stationary member. A biasing element, such as a spring, causes the door of the receiver cover to be biased in a closed position over the stationary element of the receiver cover. Thus, when the receiver is not in use, the door automatically closes and is secured in a closed position over a receptacle in a receiver with which the receiver cover is used. When access to the receptacle of the receiver is desired, such as for coupling a trailer hitch therewith, the door may be manually opened against the bias of the biasing element so as to expose the receptacle.
