    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.
