To improve a trailer device for motor vehicles, comprising a holding unit for a crossmember mountable on a vehicle body on the rear-end side thereof and a ball neck receiving body having a ball neck receptacle, in which an insertion portion of a ball neck supporting a coupling ball is insertable and fixable therein, wherein the ball neck receiving body is arranged mounted on the holding unit so as to be pivotable at least between a working position, in which a ball neck is insertable by means of its insertion portion into the ball neck receptacle, and a rest position, it is proposed that the trailer device comprises a locking device which fixes the ball neck receiving body in the rest position in a locking state relative to the holding unit and has an unlocking state, in which the locking device allows the ball neck receiving body to pivot from the rest position in the direction towards the working position, and that an actuator is provided, by means of which the locking device is movable from the locking state into the unlocking state.

A vehicle jack configured to provide lifting of either the front end or the rear end of the vehicle wherein the vehicle jack is operably coupled to a winch secured to the vehicle. The vehicle jack includes a frame having a vertical support member wherein the vertical support member further includes a base member secured to the first end thereof. The vehicle jack includes a vehicle attachment assembly that is slidably coupled to the vertical support member and is provided in a first embodiment operable to secure to the rear end of a vehicle and a second embodiment that is configured to be secured to the front end of the vehicle. The first embodiment of the vehicle attachment assembly is configured to operably couple with a frame hitch. The second embodiment of the vehicle attachment assembly operably couples to the front bumper.

An improved coupler for a tongue on a towed vehicle that attaches to a tow hook mounted on a towing vehicle to either pull the towed vehicle over a road or to pull the towed vehicle located on an elevated surface. The coupler includes an elongated tongue tube attached to the end of the tongue attached to the towed vehicle. Upper and lower rings are axially aligned and mounted or attached to the front surface of the tongue tube. The rings are spaced apart on the tongue tube to allow the towing vehicle to pull or push the towed vehicle over the same roadway or an elevated surface. Brackets are used between the tongue tube and the trailer tongue to prevent compression, collapse, and fore to aft or aft to fore movements. An adjustable jack is attached to the side of the tongue tube. An optional lid is provided over the top opening of the tongue tube that covers a storage compartment inside the tongue tube. An optional chock holder plate and a pair of compatible chocks may be placed inside the storage compartment.
