  • Patent number: 8419041
    Abstract: A hitch, which can be rigidly yet removably attached to a vehicle-mounted sleeve, comprises a longitudinally extending member which is configured to slide into the sleeve and which locks therewith with a transverse locking device in a conventional manner. The member is divided into two sections along a plane which is inclined with respect to the longitudinal axis of the member. The sections are connected together by a bolt threading into one section while being operable from the outside of the other section. Due to the inclined plane separating both sections, tightening of the bolt causes the sections to slide in opposite directions within the sleeve until they abut and press on opposite inner walls of the sleeve, thereby eliminating play between the member and sleeve. The hitch is conceived such to prevent a user to drive without the locking device in place.

  • Patent number: 7806425
    Abstract: A trailer hitch having a retaining latch bolt to reduce shaking includes a locking head, a bolt seat, a retaining element, a latch bolt and an elastic element. The retaining element has a first directing rib to be rapidly positioned in a first bolt aperture of a first coupling member. The bolt seat has a positioning rib anchored in a second bolt aperture of a second coupling member to facilitate coupling of the first coupling member and the second coupling member. Hence the latch bolt can be coupled easily and adjustment of coupling tolerance can be performed as desired. Locking can be done to thwart pilferage of the trailer. And the latch bolt can be held firmly without sliding or shaking.

  • Publication number: 20100201102
    Abstract: A pin-engaging drawbar and lock plate assembly is designed to mount and stabilize in the drawbar of a trailer hitch or alternative trailer and accessory hitch or receiver assembly. In one embodiment the pin-engaging drawbar and lock plate assembly includes a bolt extending into the drawbar, typically having the bolt head secured to a lock plate positioned beneath a locking pin extending transversely through the receiver and the drawbar. An angle brace is fixed to the lock plate and engages the locking pin, and the locking pin openings are typically vertically elliptical or elongated in the drawbar to facilitate rotating a nut on the extending threaded end of the bolt and forcing the angle brace against the locking pin, thus tightening the drawbar against the hitch receiver.

  • Patent number: 7740267
    Abstract: A nesting stabilizing device for limiting the rotation of accessories connecting to a hitch receiver with an outward end defining an opening. The outward end of the hitch receiver has a protruding ring about an outward surface. The nesting stabilizer has a base with a body portion receivable in the hitch receiver and also has a flanged collar for engaging the protruding ring on the hitch receiver in an interference fit, the flanged collar further being coupled with an accessory. In addition, the nesting stabilizer includes a fastener operatively connected with the base for urging the flanged collar against the outward end to cause the flanged collar to engage the protruding ring on the outward end. The nesting stabilizer connects the accessory to the hitch receiver upon engagement of the flanged collar with the protruding ring on the hitch receiver.

  • Patent number: 7726681
    Abstract: A receiver hitch arrangement includes a receiver tube, a mount having a shank portion received within the receiver tube and a hitch pin inserted through hitch pin apertures which are formed in both the receiver tube and the shank portion and which are aligned at assembly to maintain the mount in a position for towing. A rattling that is usually caused due to movement between hitch components. is prevented by forming a pair of through and threaded apertures in each vertical wall of the receiver tube and in close proximity to a free end thereof, threadeably engaging a threaded shank of a fastener with each of the pair of apertures and then operably advancing each fastener for direct contact with the shank portion of the mount inserted into the receiver tube until the shank portion is frictionally caged and immobilized.

  • Patent number: 7717455
    Abstract: A drawbar assembly includes a shank that can slidingly engage a first hitch receiver having an interior opening with a first size, which may be a class I receiver with a one and one-quarter inch square opening and provisions for a one-half inch hitch pin. First and second adapter parts, each having two sides forming a right angle, are removably coupled to the shank on opposite sides. The drawbar assembly can slidingly engage a second hitch receiver having an interior opening with a second size, which may be a class III receiver with a two inch square opening and provisions for a five-eighths inch hitch pin. A threaded hitch pin may clamp the drawbar assembly to the receiver.

  • Patent number: 7600774
    Abstract: A hitch adapter comprises an inner square tube member for receiving Class-II 1.25? drawbars and an outer U-channel member for plugging into a Class-III 2? receiver. The inner square tube and outer U-channel members are welded together such that one wall of the inner square tube bridges the gap between the distal edges on opposite legs of the outer U-channel. One such leg of the outer U-channel is longer than the other and is positioned and aligned to protrude about 1/16? beyond the adjacent outer corner of the inner square tube member. Such protrusion nests into the respective inside corner of the particular Class-III 2? receiver it is mated to. The protrusion provides a camming action to take up any looseness and slack, and thereby eliminate wobble and rattle when installed by a user. A series of hitch pin holes allows a threaded hitch pin to pass through the adapter, a Class-II 1.25? drawbar and a Class-III 2? receiver. Threads inside the Class-II 1.

  • Publication number: 20090250903
    Abstract: A nesting stabilizing device for limiting the rotation of accessories connecting to a hitch receiver with an outward end defining an opening. The outward end of the hitch receiver has a protruding ring about the outward surface, fully encompassing the outward end. The nesting stabilizer has a base with a body portion receivable in the hitch receiver. The body portion is adapted for coupling with the hitch receiver to locate the base in a predetermined position thereon. The nesting stabilizer also has a flanged collar for engaging the protruding ring on the outward end of the hitch receiver in an interference fit upon engagement of the flanged collar with the protruding ring on the outward end, the flanged collar being coupled with the accessory. In addition, the nesting stabilizer includes a fastener operatively connected with the base for urging the flanged collar against the outward end to cause the flanged collar to engage the protruding ring on the outward end.

  • Patent number: 7594673
    Abstract: A collar or sleeve configured to lie snugly adjacent the cavity formed by the inner wall of a bumper hitch receiver, and including a longitudinal gap allowing the sleeve to resiliently flex inwardly to facilitate insertion of the sleeve within the receiver, to assure contact with the inner wall of the receiver. The device may also include a flange or lip outstanding from the trailing edge of the sleeve, to prevent insertion within the receiver too far to allow easy extraction when no longer needed; a finger curl may also extend rearward from the sleeve, to facilitate extraction of the sleeve from the bumper hitch receiver.
