Trailer for all-terrain vehicle
First Claim
1. Detachable all-terrain trailer which is suitable for use with an all-terrain vehicle, characterisedin that the trailer includes a frame and a trailer axle;
- in that the trailer includes left and right road wheels, one at each end of the trailer axle;
in that the trailer includes a hitching link, which is secured to the frame of the trailer;
in that the hitching link includes a hitching connection, which is suitable for attaching the link to a hitching point on the vehicle;
in that the hitching connection includes a universal-joint means, which is effective, when attached to the said hitching point, to permit the trailer to move, substantially freely, in a universal mode, i.e. in a pitch mode, in a roll mode, and in a yaw mode, relative to the vehicle;
in that the trailer includes a spring means;
in that the spring means is suitable for attachment to, and for operative engagement with, the rear of the vehicle;
in that the spring means is so constructed and arranged that the spring means acts, when attached to the vehicle;
(a) to resiliently urge the rear of the vehicle upwards, thereby to transfer some of the weight of the vehicle to the trailer; and
at the same time(b) in the event that the trailer becomes deflected to right or left of the vehicle in the yaw mode, about the hitching connection, to resiliently urge and restore the trailer positively to a directly trailing position, in line behind the vehicle.

Abstract
The trailer disclosed is hitched to an all-terrain vehicle, particularly an all-terrain tricycle, not just by the conventional universal-swiveling trailer hitch but also by spring struts. The springs extend and converge forwards and upwards from the ends of the trailer axle to attachment points behind the seat of the vehicle. The springs aid in making the combined vehicle and trailer more manageable over rough ground. The springs especially curb a tendency of a tricycle when under power to rear up at the front. The invention is particularly for use when tracks are added between the trailer wheels and the vehicle wheels.
