8/562201

Inventors:

Russell S. Robinson - Tucson AZ

International Classification:

B62K 2700

US Classification:

280204

Abstract:

Appl. No.:

5/478935

Inventors:

Russell S. Robinson - Tucson AZ

International Classification:

B62K 2702
B62K 2712

US Classification:

280204

Abstract:

A two-wheeled trailer for towing behind a cycle having a tongue which extends forwardly and on one side of the rear end of the rear wheel of the cycle. The forward end of the tongue is provided with a conveniently disconnectable hitch which is mounted on one side of the cycle and usually adjacent the rear wheel axle of same. The hitch comprises a resilient member having a pivotal connection disposed between the tongue and the cycle which provides the trailer with freedom of movement about one axis relative to the cycle, the resilience of the member providing the trailer with freedom of movement about the other two axes relative to the cycle.

Abstract:

A resilient suspension means for vehicles having at least one pair of oppositely disposed wheels, said suspension means being particularly adaptable to trailers for towing behind bicycles and mopeds. Said suspension means comprises a transversely-disposed flexurally resilient axle component having axle shafts at each end for rotatably supporting a wheel, said component usually being formed with a downwardly-concave curvature and the center of said component being connected to the center of the body of the vehicle in such manner that the outer ends of said component can move substantially vertically, longitudinal movement of the ends of said component being prevented by a device connected to said body which restrains said outer ends of said component against forward or rearward movement. Stops may be provided which impart an upward deflection and strain to the ends of said axle component to minimize excessive bouncing. The invention also provides for upwardly-extending structures to be connected to the ends of said resilient axle component outside the sides of the body of the vehicle, to the top ends of which structures the axle shafts are connected in such manner that the center of gravity of the vehicle may be lowered, or larger diameter wheels may be fitted without raising said center of gravity, or both.
