摘要： 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.

摘要： In conjunction with a cycle trailer having a frame the front reach of which consists of rounded tubing or bar, a universal-joint hitch consisting essentially of two diametrically opposed wafer-like sector bearings each of which contains on its face multiple diametrally disposed sector channels, in order to render easy the assembly of the trailer to one such sector channel in the bearings. The bearings include trunnions and integral annular thrust surfaces on their opposite faces. Through the thrust surfaces, the bearings are constrained to bear on the rounded tubing or bar of the frame from opposite directions by clamping and mounting arrangements which may include a hinge on one side of the bearings and a hand nut on the opposite side. This hand nut, when employed, is restrained from unwanted loosening by contrived interference or engagement, most conveniently through glancing interference of protrusions of its handle with the trunnion of one sector bearing. The hitch may be mounted sandwich-wise to the rear frame of the cycle by a single bolt and a sandwich plate or member which embraces a slot disposed in such wise that easy but secure assembly of the hitch to the cycle is enabled. A convenient arrangement is described for suspending a bag from the frame of a trailer while allowing easy removal of the bag when desired.
