ABSTRACT:
A hitch (10) for attaching an item of equipment to be towed, e.g. a caravan or trailer, to a towing vehicle, such as a car, comprises a framework (12) carried by at least one road wheel or roller (30) located between the rear of the car and the forward end of the caravan. A towbar (40) is connected to the framework (12) for attachment to the caravan, e.g. via a ball and socket connection for detachably joining the framework (12) to the rear of the car. Use of the hitch (10) means that the forward weight of the caravan is not supported on the rear of the car as with a conventional ball and socket hitch, but by the intermediate framework (12) and road wheel(s) attached to the rear of the car, improving road handling and allowing a greater load to be towed. Ease of hitching and unhitching is also greatly improved. The wheels are attached to the framework of the hitch by telescoping supports containing airsprings. These are formed by one or more airbags (24) containing pressurized air. The framework is conveniently formed from hollow tubing to reduce weight.
