| 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.

We claim:
1. In conjunction with a one-wheeled trailer adapted to be towed behind a two-wheeled towing vehicle such as a bicycle, motorcycle, or moped and secured to the seat post thereof, said towing vehicle having a normally upright position with said trailer normally being in an upright position directly behind and in longitudinal alignment with said towing vehicle, said trailer comprising a trailer frame which frame comprises a front transverse reach of rounded material, the trailer hitch apparatus comprising
- a block and a cap connected by removable fastening means which together between them about equally define a split hole, whereby said seat post is captured so as to constitute a nonrotating journal about which said block and said cap are free to pivot, the hitch being further characterized in that
- said block is placed behind said seat post and defines within itself a horizontally disposed, rearward-facing slot which partially captures said rounded front reach of said tailer frame, said capturing being completed on the rearward side of said front reach of trailer frame by means of a movable blocking device, said capture allowing said front transverse reach of said trailer frame to rotate about a generally transverse horizontal axis.
