| 20090014983 | System and method for preventing rattling in receiver hitch arrangement - The present invention prevents rattling in a receiver hitch arrangement including 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. Such rattling is caused due to movement between hitch components and is prevented by forming a pair of through and threaded apertures in at least one predetermined 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. | 01-15-2009 |
| 20090115165 | HITCH BAR ASSEMBLY - A hitch assembly is provided having a hitch shank configured to be received within an opening of a hitch receiver of a tow vehicle and a wedge member disposed about the hitch shank. The wedge member has first and second surfaces on opposing sides of the wedge member, angled relative to one another. An engagement device is coupled to the wedge member to press the wedge member to an engaged position that causes the hitch shank to bias away from the receiver tube to minimize play therebetween. | 05-07-2009 |
| 20090250903 | Nesting stabilizer - 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. The nesting stabilizer connects the accessory to the hitch receiver upon engagement of the flanged collar with the protruding ring on the outward end of the hitch receiver. | 10-08-2009 |
| 20100201102 | Pin-engaging drawbar and lock plate assembly - 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. In another embodiment the bolt extends through a slotted front stabilizing plate to the lock plate and rotating the nut forces the lock plate against the hitch receiver and the angle plate and further tightens and stabilizes the drawbar against the hitch receiver. A second stabilizing plate can be provided rearwardly of the angle brace for engaging the drawbar and the hitch receiver and further stabilizing the assembly inside the hitch receiver. The locking action in all embodiments substantially eliminates both vertical and horizontal slack or play between the drawbar and the hitch receiver. | 08-12-2010 |
| 20100283225 | ANTI-RATTLE HITCH ASSEMBLY - An anti-rattle hitch ( | 11-11-2010 |
| 20110210530 | Tow hitch - A tow hitch for connecting a towing vehicle to a towed vehicle or other towed object including a receiving member to receive an insert member. The insert member has multiple connectors for selected use in securing a towed vehicle or other towed object, and a wedge secured to the insert member so that the wedge is positioned on a top surface of the insert member and between the insert member and the receiving member and is held against working it's cog out from between the insert and receiving member during us. | 09-01-2011 |
| 20120018980 | RING-MOUNT JOINT - A ring-mount joint between two vehicle units of an articulated bus, with the joint comprising two cantilevers, wherein each cantilever is arranged on one of the vehicle units, with each cantilever comprising a slewing ring, wherein the two slewing rings of the cantilever are mounted in each other so that they can be pivoted, wherein a damping device is provided for damping the rotational motion of the two cantilever relative to each other, wherein in the space enclosed by the inner slewing ring, there is arranged an annular chamber damper, wherein the annular chamber damper comprises two inter-mounted housing parts that are rotatable relative to each other, wherein the one housing part is in connection with the one cantilever and the other housing part is in connection with the other cantilever. | 01-26-2012 |

| 20140327228 | ANTI-RATTLE DEVICE FOR RECEIVER HITCHES AND ACCESSORIES - An anti-rattle device is shown and described. The anti-rattle device may include a pin member configured for insertion into aligned apertures of a draw bar and receiver hitch, and a block member configured to be inserted into an interior cavity of the draw bar and to receive the pin member. The anti-rattle device may also include an engaging member engaged with the pin member outside of the draw bar and receiver hitch, where the engagement of the engaging member, the pin member and the block are operable to clamp the draw bar against the receiver hitch. | 11-06-2014 |
| 20150076793 | ANTI-RATTLE DEVICE WITH HITCH COVER - An anti-rattle device is shown and described. The anti-rattle device may include a frame configured to engage a receiver hitch and to receive a draw bar. The anti-rattle device may also include a cam engaging assembly operatively engaged with the frame, where the cam engaging assembly is selectively positionable between disengaged and engaged positions whereby the cam engaging assembly is adapted to engage the draw bar against the receiver hitch in the engaged position. | 03-19-2015 |
