Abstract

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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 104 words
In a vehicle having a body and oppositely disposed wheels, a resilient suspension comprising a flexurally resilient axle component disposed transversely across said body, the center of said component being connected to said body, and each end of said component having an axle shaft extending outside the sides of said body and adapted to rotatably support a wheel, and a device connected to said body which restrains the outer ends of said component against forward or rearward movement, said device comprising channel means having a web connected to said body, and flanges between which the outer portions of said component can move substantially vertically.
Claim 2
Dependent Claim 104 words
In a vehicle having a body and oppositely disposed wheels, a resilient suspension comprising a flexurally resilient axle component disposed transversely across said body, the center of said component being connected to said body, and each end of said component having an axle shaft extending outside the sides of said body and adapted to rotatably support a wheel, and a device connected to said body which restrains the outer ends of said component against forward or rearward movement, said device comprising channel means having a web connected to said body, and flanges between which the outer portions of said component can move substantially vertically.
Claim 3
Dependent Claim 118 words
In a vehicle having a body and oppositely disposed wheels, a resilient suspension comprising a flexurally resilient axle component disposed transversely across said body, the center of said component being connected to said body and the outer ends of said component being formed to comprise upwardly extending wings disposed outside the sides of said body, the upper end of each said wing having an axle shaft connected thereto, and a device connected to said body which restrains the outer ends of said component against forward or rearward movement, said device comprising channel means having a web connected to said body and opposite flanges between which the outer portions of said component and said wings can move substantially vertically.
Claim 4
Dependent Claim 118 words
In a vehicle having a body and oppositely disposed wheels, a resilient suspension comprising a flexurally resilient axle component disposed transversely across said body, the center of said component being connected to said body and the outer ends of said component being formed to comprise upwardly extending wings disposed outside the sides of said body, the upper end of each said wing having an axle shaft connected thereto, and a device connected to said body which restrains the outer ends of said component against forward or rearward movement, said device comprising channel means having a web connected to said body and opposite flanges between which the outer portions of said component and said wings can move substantially vertically.
Claim 5
Dependent Claim 40 words
A resilient suspension according to claims 1 or 2 in which said device is provided with stops disposed adjacent each end thereof, each said stop cooperating with an outer portion of said component to restrain same against excessive downward movement.
