Abstract
A coupling system that uses a standard receiver box found on most new vehicles to attach a coupler with a universal joint allows full movement between the vehicle and the trailer, including vertical, lateral and rotational motion. The device also incorporated lubrication fittings so that it can be lubricated in the field. The rear of the universal joint has a spindle that extends rearward. The spindle fits through a sleeve that is used to attach the unit to the trailer. The spindle is rotatable secured in the sleeve with a nut and a pin, to provide the 360 degrees of rotation. A limiter plate can be installed to limit the rotation of the trailer in use. The sleeve has two flat side plates that are bolted to the trailer tongue. The unit provides a strong, compact functional hitch system.
Claims17
A coupler for trailers for use with an all terrain vehicle, or the like, having a box hitch receiver installed thereon, comprising:
- a) a universal joint mechanism having a first end and a second end;
- b) a shaft, attached to the first end of the universal joint and extending outwardly therefrom, said shaft being sized to fit into the box hitch receiver on said all terrain vehicle;
- c) a means for temporarily securing and retaining said shaft in said box hitch receiver;
- d) a spindle, attached to the second end of said universal joint and extending outwardly therefrom, said spindle having distal end and further wherein said distal end has a plurality of threads formed thereon;
- e) a sleeve, slidably placed onto said spindle such that said spindle is rotatably fitted within said sleeve;
- f) a means for securing said sleeve onto said spindle;
- and
- g) a means for attaching said sleeve to a tongue of a trailer, fixedly attached to said sleeve wherein said means for attaching comprise:
- i) a flat bottom plate, fixedly attached to said sleeve;
- ii) a pair of oppositely disposed side plates, attached to said flat bottom plate and extending downward therefrom;
- and
- iii) at least one fastener to attach said pair of oppositely disposed side plates to said tongue of said trailer.
A coupler for trailers for use with an all terrain vehicle, or the like, having a frame member for receiving a hitch ball installed thereon, comprising:
- a) a universal joint mechanism having a first end and a second end;
- b) a shaft, attached to the first end of the universal joint and extending outwardly therefrom;
- c) a spindle, attached to the second end of said universal joint and extending outwardly therefrom, said spindle having distal end and further wherein said distal end has a plurality of threads formed thereon;
- d) a sleeve, slidably placed onto said spindle such that said spindle is rotatably fitted within said sleeve;
- e) a means for securing said sleeve onto said spindle;
- f) a means for attaching said sleeve to a tongue of a trailer, fixedly attached to said sleeve, including:
- i) a flat bottom plate, fixedly attached to said sleeve;
- ii) a pair of oppositely disposed side plates, attached to said flat bottom plate and extending downward therefrom;
- and
- iii) at least one fastener to attach said pair of oppositely disposed side plates to said tongue of said trailer;
- g) an adapter receiver box, including:
- i) a box portion for receiving said shaft;
- and
- ii) a means for attaching said adapter receiver box to said frame member for receiving a hitch ball;
- and
- h) a means for temporarily securing and retaining said shaft in said box portion.
