Abstract
A vehicle extender is connected to a towing vehicle by way of a towing beam bolted to the normal tow hitch and presenting two ball and socket joints so that the vehicle extender can pitch upwardly and downwardly but cannot yaw from left to right nor roll clockwise or anti-clockwise relative to the vehicle. The vehicle extender has a single castor mounted wheel set so located that even in reversing mode in which by castor action the wheel set swivels to a forward located position the center of gravity of a load in the vehicle extender such as sand still remains forwardly of the horizontal axis of rotation of the wheels of the wheel set providing for security and stability in use. The vehicle extender is very adaptable to different applications.
Claims8
A vehicle extender provided with two horizontally spaced apart pivotal connectors for connection to a towing vehicle and adapted to restrict swingable movement of the vehicle extender relative to the towing vehicle, including structure defining a load space and a single caster attached to the vehicle extender, the caster swivelably attached to a rear portion of the vehicle extender so that a horizontal axis of rotation of a wheel of the caster does not extend forwardly of a centroid of the load space of the vehicle extender, the caster including:
- a downwardly depending shaft attached to an underneath portion of the vehicle extender and;
- a suspension device attached to the downwardly depending shaft, wherein:
- an axis of the downwardly depending shaft is at a non-orthogonal angle with respect to said underneath portion of the vehicle extender so that the plane of swivelling of the caster is angularly offset with respect to said underneath portion of the vehicle extender, the axis of the downwardly depending shaft being in a vertical longitudinally directed plane and inclined forwardly.
