The inventive disclosures described herein pertain to an improved folding trailer that is comprised of an improved load-absorbing swivel jack featuring a load-absorbing torsion-spring assembly to more-easily aid in safe trailer-folding operations, a hinged trailer tongue, an integral winch with an extended flexible coupling shaft, and an external or onboard rotational power source to drive the winch. More specifically, this folding-trailer configuration minimizes the physical exertion required of a user to fold or unfold the trailer, as well as significantly reduces the potential for serious user injury during the folding/unfolding process. The improved folding trailer also features foldable cargo-containment sides and multi-positionable tailgate, as well as removable/configurable cargo-carrying racks/rails.

One example embodiment is a tow bar retention mechanism for a vehicle tow bar of a combat vehicle. The tow bar retention mechanism includes a tow bar retention arm, an elongated locking beam, a quick-release locking mechanism, and a quick-release safety mechanism. The quick-release locking mechanism locks the tow bar retention arm in a locked position placing the vehicle tow bar in a stowed position. The quick-release locking mechanism also unlocks the tow bar retention arm allowing the tow bar retention arm to move to an unlocked position allowing the vehicle tow bar to move to a tow position. The quick-release safety mechanism may be placed in a first position preventing the quick-release locking mechanism from moving from the locked position. The quick-release safety mechanism may also be placed in a second position allowing the quick-release locking mechanism to move from the locked position.

A towbar with a hitch ball system is shown and described. The towbar with a hitch ball system may include a first bushing member, a second bushing member telescopingly engaged with the first bushing member, the second bushing member including at least one aperture, and a pivoting arm telescopingly engaged with the second bushing member. The towbar with a hitch ball system may also include an engagement device operatively coupled with the second bushing member, the engagement device including a pin member and an electrically-operating device, where the electrically-operating device generally aligns the pin member with the at least one aperture of the second bushing member.

In order for a trailer hitch, comprising a pivot bearing unit mountable on a rear end portion of a vehicle body, in fixed relation to the vehicle, and a pivot element supported on the pivot bearing unit for pivotal movement about at least one pivot axis, said pivot element having fixedly connected thereto a ball neck carrying a hitch ball, said ball neck being pivotable, by pivoting the pivot element about the at least one pivot axis relative to the pivot bearing unit, between two final positions, one of which is an operating position and another one of which is a rest position, to be improved such that the location of the pivot element can be detected as simply and unambiguously as possible, it is proposed that a sensor system be provided for detecting at least one location of the pivot element relative to the pivot bearing unit with respect to the at least one pivot axis, which sensor system detects the locations of the pivot element relative to the pivot bearing unit mounted in fixed relation to the vehicle and generates position information representative of the respective location of the pivot element.

The inventive disclosures described herein pertain to an improved folding trailer that, in many embodiments, is comprised of an improved swivel jack to more-easily aid in safe trailer-folding operations, a hinged trailer tongue, an integral winch with an extended flexible coupling shaft, and an external or onboard rotational power source to drive the winch. More specifically, this folding-trailer configuration minimizes the physical exertion required of a user to fold or unfold the trailer, as well as significantly reduces the potential for serious user injury during the folding/unfolding process. The improved folding trailer also features foldable cargo-containment sides and multi-positionable tailgate, as well as removable/configurable cargo-carrying racks/rails.

In order to improve a trailer device for motor vehicles, comprising a crossmember, which is mountable on a vehicle body at the rear-end side thereof, a holding unit, which is provided on the crossmember and which carries a ball neck receiving body comprising a ball neck receptacle, into which receiving body an insertion portion of a ball neck supporting a coupling ball is insertable and fixable therein, in such a way that the ball neck receiving body is both visible and intrusive to the least possible extent when the ball neck is not inserted, it is proposed that the holding unit comprises a pivot bearing unit, by means of which the ball neck receiving body is movable from a working position, in which the ball neck is insertable into said receiving body for trailer operation, into a rest position, and that at least one stop element fixedly connected to the holding unit is provided, which stop element has a first support surface, which, in the working position, abuts against the insertion portion with the insertion portion inserted into the ball neck receptacle and thus blocks a pivoting of the ball neck receiving body in at least one pivot direction.

A transport dolly includes a base and a tongue rotatably mounted to the base. At least one support is mounted to the base. A first cable guide is coupled to the at least one support. A lever is rotatable between a first orientation and a second orientation. A cable has a first portion attached to the tongue. The cable extends from the tongue to the first cable guide, then to the lever. The lever pulls on the cable when the lever is rotated from the first orientation to the second orientation, so as to decrease a distance between the cable first portion and the first cable guide, thereby rotating the tongue from a lowered orientation to a raised orientation. A spring mechanism exerts a force on the lever to prevent rotation of the lever from the second orientation to the first orientation when the tongue is raised.

An exemplary tow hook assembly for a vehicle includes a tow hook, a bracket, and a coupling member. The tow hook is coupled to the bracket by the coupling member. The tow hook is pivotable between a first position and a second position about the coupling member. In the second position, the tow hook is contained within a horizontal dimension and a vertical dimension defined by the bumper.

A multi-attachment trailer hitch features a shank for coupling with a receiver tube of a towing vehicle, and first and second hitch attachments of different size or type from one another movably carried on the shank by one or more supports. Each support is movably coupled to the shank for selective swiveling or rotation thereof about an upright axis to move one or more of said hitch attachments between a working position situated rearwardly beyond the rear end of the shank, and a storage position situated more forwardly than the working position. The one or more supports are movable into a full-storage state in which no hitch attachment occupies the working position, thereby eliminating or minimizing a rearward projection of the hitch from the rear of a towing vehicle to reduce or eliminating tripping or rear-end puncture hazards.

A trailer coupling for a motor vehicle is disclosed, which comprises a carrier assembly having a transverse carrier designed as a profiled part and a retainer retained on the transverse carrier for retaining a coupling element, of the trailer coupling, wherein the coupling element is provided for fastening a trailer or a load carrier, wherein the retainer is connected to the transverse carrier by a tension anchor of a tension anchor assembly wherein the tension anchor penetrates the transverse carrier along the tension anchor load axis of the tension anchor and loads an abutment surface of the retainer, through which abutment surface the tension anchor load axis or an axis parallel to the tension anchor load axis passes, against a side wall of the transverse carrier, said side wall having a through-opening for the tension anchor wherein the tension anchor assembly has a support element having a support surface and a support protrusion, which protrudes from the support surface in the direction of the tension anchor load axis and which engages in the through-opening of the side wall, wherein the support surface of the support element is supported on the side wall of the transverse carrier next to the through-opening by at least one force component in the direction of the load axis and the support protrusion is supported in the through-opening by at least one force component transverse to the load axis.
