20090302573 | DUMP TRAILER COUPLING APPARATUS - A dump trailer coupling apparatus is described. The apparatus is joins a vehicle hitch to the push tongue of a trailer in a way that accounts for and permits all movements of the dump trailer when on a roadway and during the dump process, without translating that stress to the hitch. In one embodiment, the apparatus is a swivel coupler including a pair of swivel structures. The first swivel structure enables lateral movement of the trailer with respect to the vehicle. The second swivel structure enables complete dumping of the trailer without stress on the hitch. In another embodiment, the apparatus is a hinged coupler including a support plate, a ball mount and a ball coupler. The ball coupler retains a roller that moves along on the support plate and addresses lateral movement of the dump trailer. The ball coupler includes a hinge connector attached to the trailer push tongue and enables complete dumping of the trailer without stress on the hitch. | 12-10-2009 |

20130020785 | COUPLER ASSEMBLY - The present application describes a gooseneck coupler assembly that may include a gooseneck trailer pivot, an extension arm, and a pivot retention mechanism having a ball socket. The ball socket may engage with a hitch ball located on a towing vehicle. The gooseneck trailer pivot may be mounted on a towed vehicle or trailer and be capable of pivoting about a vertical axis relative to the trailer. During engagement, the ball socket and the extension arm may provide tilt capability but thereby prevent any rotational movement relative to the hitch ball. However, the gooseneck coupler assembly may still be able to tilt fore-and-aft or side-to-side relative to the hitch ball. Therefore, the only pivotal movement relative to a vertical axis would be permitted at the gooseneck trailer pivot. | 01-24-2013 |

20110254250 | SWIVEL HEAD ASSEMBLY - Various embodiments of the present invention comprise apparatus, assemblies and methods for towing a vehicle using a swivel head assembly. The swivel head assembly can permit a grid head of a towing system to roll as well as yaw with respect to a tow arm. Spring members are also provided that can help dampen roll motions. | 10-20-2011 |
20130056957 | Off-Road Hitch Assembly - Disclosed is an improved all terrain vehicle (ATV) trailer hitch system, comprising a first and second pivotal joint connected by an elongated driveshaft for navigating uneven terrain and maneuvering through tight turns without joint binding or trailer tipping. The driveshaft comprises a length adjustable member having a first end connecting to a lead vehicle via a first pivotal joint that statically supports the joint and allows pitching of the driveshaft. The driveshaft second end attaches by way of a second pivotal and rotatable joint to a trailer attachment assembly. The trailer attachment assembly provides connection to the trailer and for receiving an elongated drive screw member that establishes a rotational joint. The second pivotal joint therefore provides yaw and roll capability for the trailer. The system provides a multiple joint connection separated by an elongated driveshaft between a vehicle and a trailer for reduced binding and off-road maneuvering. | 03-07-2013 |
20130140792 | DRAWBAR HITCH ADAPTER PROVIDING ROLL AND PITCH FREEDOM - An adapter for connecting a agricultural implement swivel hitch to a drawing hitch on a towing vehicle that enables relative pitch and roll movement between the implement and vehicle at a single, pinned joint. Elongated openings in a first portion of the hitch adapter receive a transversely aligned connection pin. The openings are sized to allow limited pin angular movement about a vehicular roll axis. A second portion of the hitch adapter is also connected to the connection pin and configured to allow limited relative angular movement about a transverse pitch axis. The connection between the first and second portions at the connector pin allows relative angular movement therebetween about generally co-planar pitch and roll axes. The connector pin is formed from a softer material than the surrounding first and second portions thereby providing an inexpensive and easily replaceable weak link in the hitch adapter assembly. | 06-06-2013 |
20150334910 | Swivel Drawbar Hitch Mechanism for Pull-Type Implement - A drawbar hitch mechanism has a fore-and-aft extending receiver, a gearbox assembly coupled to the receiver and a tongue assembly attached to the gearbox assembly. A first pivot mechanism couples the receiver with the gearbox assembly for side-to-side movement about a longitudinal axis of the receiver. A draft arm is configured to disperse draft loads between the tongue assembly and the receiver. A second pivot mechanism couples the gearbox assembly and the draft arm. The second pivot mechanism is oriented such that it pivots about an upright axis such that the gearbox assembly and second pivot mechanism enable pivoting movement of the tongue assembly relative the receiver. | 11-26-2015 |
