  • Patent number: 9707811
    Abstract: A multi-function, anti-rotational, power-sports utility hitch receiver assembly includes a four-sided hollow receiver tube having a forward end configured to attach to a tow vehicle and a rearward end configured to house an attachment of an accessory shank. Aligned apertures are present in the opposing sidewalls between the forward end and the rearward end for securing a hitch accessory shank within the receiver tube by inserting a hitch-pin through apertures. A removable, adjustable tightening bar is attachable to an underside of the hitch receiver tube for maintaining the receiver tube in a stationary position when the receiver tube is installed on a tow vehicle by abutting a surface on the tow vehicle. The assembly further includes a tow loop, e.g., for attaching tow chains, straps, bungee cords, tow hooks and the like to the receiver.

  • Patent number: 9630463
    Abstract: A hitch accessory retaining device includes a pair of opposed engagement pins and a biasing device. When positioned within a shank body, the engagement pins are slidable within shank pinning apertures and are normally urged in outward, extended positions by the biasing device. When biased outwardly, a portion of each engagement pin extends outwardly from and projects beyond a shank sidewall while an additional portion of each engagement pin is retained within the shank body. A portion of the biasing device contacts, is attached to, or is part of, the engagement pins. The normally outwardly biased engagement pins are biasable inwardly to a retracted position within the shank pinning apertures to a position wherein the outward ends of the engagement pins are flush with the outward sides of shank sidewalls.

  • Publication number: 20160137012
    Abstract: A hitch accessory retaining device includes a hitch pin having a first end and a second end. The second end is configured to be inserted completely through a hitch receiver and an accessory shank. The hitch pin includes a first shank portion and a second shank portion. The second shank portion has a smaller diameter than the first shank portion, such that a shoulder is formed between the first shank portion and the second shank portion. The hitch pin includes an externally-threaded region. At least a portion of the hitch pin is configured to be located within a hollow cavity of an accessory shank when an accessory shank is installed and pinned within a hitch receiver.

  • Patent number: 8840130
    Abstract: The maximum security/maximum versatility ball mount assembly provides an assembly for securing a ball mount or other accessory shank to a receiver hitch on automotive vehicles, tractors, ATVs, and other vehicles equipped with a receiver-type hitch. As the shank of a hitch accessory or implement is inserted into a receiver, dual retractable hitch pins automatically engage the receiver when the pins align with the two hitch-pin apertures in the receiver tube, thereby securing the ball mount/accessory's shank to the vehicle's receiver. A shank end cap shields the hitch pin assembly's internal components from dirt and/or rust particles, and the end cap also serves as an innovative and useful alignment aid when inserting the shank into a vehicle's receiver.

  • Patent number: 8376387
    Abstract: The Multi-Function Anti-Rotational/Anti-Theft Hitch Ball Assembly of the present invention provides a trailer hitch assembly that includes an anti-rotational hitch ball mechanism that can also serve as an anti-theft hitch ball mechanism and can further simultaneously function as an attachment method for securing additional hitch accessories to the ball mount. The invention provides an engagement method for interlocking the hitch ball with the ball mount preventing rotation of the hitch ball relative to the ball mount. The interlocking engagement assembly may also be locked in place preventing the hitch ball from being removed from the ball mount if the hitch ball fastener is removed. In addition, a component of the assembly can serve as an attachment method for securing additional accessories to the ball mount.

  • Patent number: 8276932
    Abstract: The multi-task trailer hitch assembly of the present invention provides receiving tubes for the attachment of one or more trailer hitch-mounted receiver-type accessories while retaining a trailer hitch for pulling a trailer in the single hitch receiver provided on many trucks and ATVs. This permits the simultaneous use of multiple accessories while retaining the concurrent ability to tow. Multiple receiver tubes can be provided, both horizontal and vertical, and oriented not only toward the rear but also at right angles from the ball mount. This permits fastening one or more attachments from not only the rear but also from the top and inward from both sides toward the ball mount. Extra hitch ball mounts and other towing accessories may also be conveniently stored in the receiver tubes of the present invention while towing with a particular Class II or Class III hitch ball mount in the appropriate vehicle-mounted hitch receiver.
