Abstract
A hitch to be used with a one-wheeled trailer to be towed by a bicycle, motorcycle, moped, or other cycle or two-wheeled vehicle. The hitch is mounted relatively permanently to the seat post of the towing cycle but is free to swivel around said seat post as the trailer tracks around curves. The frame of the trailer to be towed has a frame the front reach of which consists of transversely disposed rounded bar or tubing. The essential universal-joint connection that makes a one-wheeled trailer feasible is completed by this rounded front reach of the frame captured rotatably within a horizontally disposed, rearward-facing slot in the hitch block. The capture is completed by means of a vertical, quickly removable pin preferably containing a spring-ball plunger. The pin is inserted behind said bar or tubing. The invention enables the hitching and towing of a trailer while leaving the trailer free to track around curves and over rough roads and paths, yet at the same time keeping the trailer normally upright by preventing its rotation around a longitudinal axis unless the cycle tilts or falls over with it. The bearing surfaces are normally lined with inserts of polyamide (nylon) strip or other bearing-quality material. These bearing linings prevent undue wear, scuffing and rattling.
