ABSTRACT:
This invention is a hitch device particularly adapted for connecting a single wheel trailer to a bicycle. The ball member of the hitch device is connected to the bicycle frame. The cup member for coupling to the ball is connected to the end of the draw bar. The draw bar is provided with a depending lever, the distal end of which extends below the ball member. A bracket member is connected to the bicycle frame for anchoring one end of a spring member. The other end of the spring member is connected to the distal end of the depending lever. The distal end of the depending lever is in vertical alignment with the center of the ball, and the spring which is under a tension bias maintains this vertical alignment during the towing operation. The hitch device of this invention provides stability to the trailer and allows the bicycle to maintain its maneuverability.
