Benefits of technology
[0006]A primary object of the invention is to eliminated the above-mentioned drawbacks and to provide a method for providing a resistance to an exercise apparatus with an inertia resistance wheel and a resistance-providing apparatus employing the same that ensures a temporary removal of the exercise resistance force within the range of the force-application dead point and a renewed provision of the exercise resistance force within the better force-acting range. In this way, the operator can easily drive the crank when the crank is just located within the range of the force-application dead point. In this way, any frustration feeling won't be created or a difficult force-application won't take place. As a result, an excellent smooth feeling is created during the whole exercise sessions.
Problems solved by technology
The reason for that lies in that the flywheel is still not ready for rotation or the inertia speed is still not enough.
Consequently, the operator will be frustrated in applying force at this moment.

Embodiment Construction
[0014]The present invention will now be described in more detail hereinafter with reference to the accompanying drawings that show various embodiments of the invention.
[0015]The resistance-providing apparatus in accordance with the invention has a mechanic or an electromagnetic control system. It will be described more hereinafter.
[0016]Referring to FIGS. 2 and 3, a mechanic resistance-providing apparatus is applied to a fitness bike 20. It is apparent from the drawings that the fitness bike 20 includes a bike frame 21, an upright frame 23 with an electronic console 22, a seat tube 25 with a saddle 24, a pedal crank 26, a sprocket 27 driven by the pedal crank 26, a transmission chain 28, an inertia resistance wheel 29, and a resistance-providing apparatus 40. A cam 30 synchronically rotatable with the pedal crank 26 is interposed between the pedal crank 26 and the sprocket 27 in such a way that the cam 30 is in constant contact with a contact portion 45 of a magnetic resistance asse...

A method for providing a resistance to an exercise apparatus with an inertia resistance wheel and a resistance-providing apparatus employing the same wherein a temporary removal of the resistance produced by the resistance-providing apparatus is achieved when a crank of the exercise apparatus is located in the range of the force-application dead point. The resistance-providing apparatus provides the original and prearranged exercise resistance when the crank is situated in a better force-acting range. In this way, the exercise process is more smoothly operable. Moreover, an expected fitness effect created by the exercise resistance can be maintained.
Description
BACKGROUND OF THE INVENTION[0001]1. Fields of the Invention[0002]The invention relates to a method for providing a resistance to an exercise apparatus with an inertia resistance wheel and a resistance-providing apparatus employing the same, and more particularly, to a method and an apparatus that permits a more smooth operation of the exercise apparatus with a satisfied fitness effect by application of a proper exercise resistance.[0003]2. Description of the Related Art[0004]The so-called exercise apparatuses with an inertia resistance wheel relates to conventional indoor exercise apparatuses including fitness bikes, an elliptical cross trainers, rowing exercisers, etc. The inertia resistance wheel is often constructed as a flywheel. A unidirectional bearing is mounted on the shaft of the flywheel. The flywheel will be in-place-rotated in single direction by the drive of a sprocket and a transmission chain 28 after the operator applies a force to the crank. Moreover, the inertia rot...
