Abstract
A front wheel shock absorbing system for a bicycle wherein the legs of the front wheel fork includes struts slidable in tubes. The struts are attached at one end to the wheel axle. The tubes slide over the struts and are fixedly secured to the forks steering tube through a triple clamp. A rim type braking mechanism is secured to the struts by a bypass attachment mechanism, preferably by the provision of a slot through the tube to permit a fastener to extend through the tube and onto the strut. The slot permits reciprocation of the strut relative to the tube. Compressible bumpers in the tube are compressed by the strut and tube interacting to provide the shock absorbing effect.
Claims10
In a bicycle, a front wheel fork, shock absorbing suspension system, said bicycle having front and rear wheels supporting a frame adapted to support a rider, the front wheel having an axle and the suspension system extending from the axle to handlebars pivotally mounted on the frame and rider controlled for turning the front wheel and thereby the direction of the bicycle, said shock absorbing suspension system comprising;
- a strut on each side of the front wheel connected to the axle and extended upwardly, a tube slidably surrounding each strut, a member connecting both tubes to the handlebars, and a biasing member between the tubes and the struts whereby upon thrusting of the strut in the tube deforms the biasing member for absorbing the upward thrusting movement, said biasing member urging return downward movement of the strut in the tube, and
- a rim actuating braking mechanism, and a by-pass connection connecting said braking mechanism to each of said struts while avoiding interference with the relative movement of said tubes.
