Abstract
Lateral stabilizer clamps, clamp kits for retrofitting such stabilizers, trailer-transporting dollies equipped with same, and methods for use thereof are variously disclosed. The stabilizer comprises a clamp operable to apply active clamping force to engage a variable-terrain-type trailer hitch coupler member in actively clamped relation against a co-operable dolly-associated clamping surface of the clamp. This engagement restrains variable-terrain lateral degrees of mechanical design freedom between the hitch coupler member and the co-operable dolly hitch member in a stabilized mutual coupling thereof.
Claims10
A variable-terrain-movement restricting clamp for use in a dolly for towing a trailer equipped with a hitch having variable terrain trailer coupler, said variable-terrain-movement restricting clamp comprising:
- a dolly coupler and a dolly-coupler-opposing, variable-terrain-movement restriction plate, respectively positionable between paired mutual clamping and unclamping positions with said trailer coupler correspondingly clamped or unclamped therebetween;
- and,
- with said dolly coupler being adapted to mutually couple with said variable terrain trailer coupler to provide anchored opposition for said restriction plate to secure said trailer coupler in clamped variable terrain movement restricting relation between said dolly coupler and said restriction plate when in said clamping position.
A variable-terrain-movement restricting clamp kit comprising a dolly-coupler-opposing, variable-terrain-movement restriction plate and an actuator, for use in a dolly having a dolly coupler for towing a trailer equipped with a hitch having variable terrain trailer coupler to provide a variable-terrain-movement restricting clamp, and wherein said dolly coupler and said dolly-coupler-opposing, variable-terrain-movement restriction plate are adapted to be respectively positionable between paired mutual clamping and unclamping positions by said actuator with said trailer coupler correspondingly clamped or unclamped therebetween;
- and, with said dolly coupler being adapted to mutually couple with said variable terrain trailer coupler to provide anchored opposition for said restriction plate to secure said trailer coupler in clamped variable terrain movement restricting relation between said dolly coupler and said restriction plate when in said clamping position.
A lunette-compatible dolly coupler comprising an inverted cone or dome for engaging tapering sidewall portions thereof in self-centering, mutually concentric contacting relation with inside ring wall portions of a compatible lunette.
