Abstract

The utility model relates to an adjusting eccentric wheel structure, which is particularly applied to a pedal wheel device. Compared with the common bicycle which can not only carry out horizontal running and riding, but also can make control a bicycle body to generate dynamic states of upper and lower fluctuation or front and back wave fluctuation in the horizontal direction during the running, the utility model is mainly characterized in that a group of structural components and a mechanical eccentric shaft principle are utilized to make pedal wheels generate a shaft eccentric state during the running rolling; in such a way, the bicycle body can generate the situation of fluctuation during the running, and the degree for the eccentric fluctuation can be adjusted.

Description

Adjustable eccentric wheel structure

The utility model relates to a kind of " adjustable eccentric wheel structure ", You Zhiqi is applied on the bicycle wheel apparatus, except that the level that can still have general bicycle advance drive, more can be controlled make advancing of car body the generation level to following, down rise and fall or forward and backward lumpy dynamically.

By " the bicycle stepless eccentric structure device " applied for before the contriver is a kind of eccentric roller car wheel structure design about foot-operated wheel, make foot-operated car body during advancing, must produce upper and lower wave or forward and backward fluctuating maybe can switch on normal flat sail state and advance during the original creation design of capable adjusting wheel swing fluctuating quantity, this design and apply for the novel patent in Taiwan on October 8th, 1997, and obtain and check and approve that to vouchsafe the patent warrant number be that No. 143641, the U.S. invent the 6th, 024, No. 367, the contriver also also successively wins Europe, day, moral simultaneously.Justice ... check and approve etc. multinational patent, and be subjected to affirming and favor of industry, the designed product of the bright contriver of sequitur has the progressive and the practicality in the quite leading world.

The above-mentioned patent that this is got permission, thereafter and under contriver's lasting research and improvement, some shortcomings at its original design, for example the spare part number causes too much that productive costs improves, structure too complexity cause industrial economies such as being unfavorable for assembling and utilize problem to be discussed, eventually success develop farther brand-new improvement design-" the adjustable eccentric wheel structure " that belongs to own patented invention originally that be better than, be enough to this product ommercialization and must be extended to sporting goods or be applied on each industry demand purposes.

Main purpose of the present utility model is to be to provide a kind of " adjustable eccentric wheel structure ", utilize this structure design, can make foot-operated car body during advancing, produces upper and lower wave or forward and backward fluctuating maybe can switch on normal flat sail state and advance during capable adjusting wheel swing fluctuating quantity to reach the double effects of sport and body-building and interest.

A purpose more of the present utility model is according to the costliness, the disadvantages that belong to proprietary design originally, is improved the economic utilization, stock production, the cost-cutting that enable to reach on the industry and respectively likes bicycle body building person to be extended to.
