Description

The two-way actuating device of trampling

[technical field]

The utility model relates to exercise and fitness equipment, relates to particularly that a kind of forward that can be used for bicycle or exercise bicycle is trampled and the reverse actuating device of trampling.

[background technology]

Because the modern city people's work is very busy, rhythm of life is very fast, and the center of gravity overwhelming majority of therefore living all is placed in the work, to such an extent as to even the time of having a holiday or vacation and lying fallow is arranged, rest often also can only stay at home.In the course of time, in case people's health does not keep the activity of physiological function by suitable motion, the thing followed then will be the burden on the spiritual aspect, and then cause situations such as work burnout, deterioration of efficiency.Therefore, move and the demand of body-building indoor, released multiple exercise and fitness equipment (as exercise bicycle) on the market in order to satisfy people.No matter be bicycle or exercise bicycle, all can only do the trample action of single direction, period of service is long can be felt uninteresting unavoidably and reduce the interest of using, and this structure of trampling has often been ignored the importance of oppositely trampling, because oppositely trampling the muscle position that moved to and forward tramples and differs widely, the effect that it brought differs widely when also trampling with forward, particularly for the people who bends over one's desk working all day or learn, oppositely tramples the hardship of allaying tiredness and aching pain in waist and back effectively.

At the problems referred to above, someone has developed and can do forward and heterodromous exercise bicycle, but, this forward can have multiple different combination with oppositely directed mode of motion, and in the process of trampling, can't turn to immediately owing to action of inertia, then can make the leg muscle damage in step, exist potential safety hazard in the use if turn to by force.

[summary of the invention]

The utility model is intended to address the above problem, and a kind of direction of trampling that can arbitrarily change pedal in the process of trampling is provided, and can not influence the two-way drive configuration of trampling of the rotation direction of flower wheel in the process that forward is trampled and oppositely trampled.

For achieving the above object, the utility model provides a kind of two-way actuating device of trampling, and it is characterized in that it comprises:
