Abstract:
A suspension system for a rotatable wheel vertically mounted in a frame, wherein said wheel has a horizontal axle aligned perpendicular to the plane of the wheel and the frame has a triangular wheel suspension component comprising:a) a first solid member with a long axis, a wide lateral side, and a relatively thin vertical side, said member being substantially more rigid laterally than vertically, said first member having a solid wide first end, and a bifurcated left/right pair of tapering segments adapted to receive the wheel, the segments having left and right second ends, said first member being solid from said first end to said left and right second ends; b) a second strut member, with a long axis, longitudinally expandable and compressible, comprising a unitary top segment with a first end and an integrated shock absorbing means adapted to dampen the longitudinal movement, and a bifurcated left/right pair of bottom segments adapted to receive the wheel, the bottom segments having left and right second ends, wherein said second left end of said second member is attached to said second left end of said first member and said second right end of said second member is attached to said second right end of said first member, and a left/right pair of wheel dropouts is integrally located proximal to the second ends of the first member and second ends of the second member and adapted to receive the axle of the wheel; and c) a rigid third member with a first and second end wherein said first end is rigidly attached to said first end of said first member, and said second end is attached to said first end of said second member.
