Spring assisted jumping bicycle

摘要

The present invention is a bicycle having a frame capable of flexing under downward force so that when downward force is applied a front spring assembly and a rear spring assembly are able to store and release the energy allowing the bike to jump in the air. The spring assemblies of the present invention use bow springs made from fiberglass/epoxy, graphite/epoxy, or fiberglass/nylon instead of traditional coil springs. The bow springs allow the spring assemblies to return a greater amount of energy than their coil spring counterparts while keeping overall weight of the spring assembly down.

主权项

1. A bicycle comprising: a two-piece frame defined by a front end and a rear end, said front end coupled to a front wheel assembly having a front wheel, at least a portion of the front wheel assembly being slidably moveable to permit said front wheel to move vertically in relation to said front end of said frame, said front wheel assembly including a front axle to permit rotation of said front wheel, and said rear end having a pivot attached to said front end and a rotatable rear wheel mounted to said rear end of said frame;
at least one bow spring having an upper end pivotally attached to said front wheel assembly and a lower end pivotally attached to said front wheel assembly, said at least one bow spring bendable to store potential energy when a downward force is applied to said frame; and at least one rear spring located a distance from said pivot, said at least one rear spring having a first end secured to said front end of said frame and a second end secured to said rear end of said frame, said at least one rear spring being compressible and configured to store potential energy when a downward force is applied to said frame; wherein a downward force applied on said front and rear ends of said frame induces said at least one bow spring and at least one rear spring to store potential energy, whereby removal of the downward force on said front and rear ends of said frame results in a release of said potential energy and propels said frame vertical such that said bicycle jumps into the air.
