Benefits of technology

The patent describes a type of exercise machine that can rotate two pedals to control the movement of the machine. When the machine is operating at a high pace, both pedals are used to move the machine. This causes one of two flywheels to rotate while the other rests. The technical effect of this design is that it creates a more natural and effective exercise experience for the user.

Problems solved by technology

In a conventional stepper using a driving mechanism composed of linkage rods, when the stepping motion is performed, the inertia of the flywheel improves the smoothness of the pedaling operation, but this is limited to a large pace (that is, a large reciprocating distance of the pedal).
When the stepper operates with a small pace, the inertia of the flywheel cannot immediately convert the stepping operation into the other direction, and hence there is blockage when switching the operation direction.

Embodiment Construction

[0027]Embodiments of the invention are now described and illustrated in the accompanying drawings, instances of which are to be interpreted to be to scale in some implementations while in other implementations, for each instance, not. In certain aspects, use of like or the same reference designators in the drawings and description refers to the same, similar or analogous components and / or elements, while according to other implementations the same use should not. According to certain implementations, use of directional terms, such as, top, bottom, left, right, up, down, over, above, below, beneath, rear, front, clockwise, and counterclockwise, are to be construed literally, while in other implementations the same use should not. While the invention will be described in conjunction with these specific embodiments, it will be understood that it is not intended to limit the invention to these embodiments. On the contrary, it is intended to cover alternatives, modifications, and equival...

Abstract

Embodiments of the present invention disclose an exercise machine including a supporting mechanism, two driving units, and a resistance device. The supporting mechanism supports the two driving units and the resistance device. The two driving units are respectively mounted at the left and the right side of the supporting mechanism for the user to operate. When the exercise machine is operated with a “small pace,” the resistance device is operated in both directions to eliminate the blockage when switching the operating direction of the driving units. When the exercise machine is operated with a “large pace,” the resistance device can provide resistance for the driving units in either direction.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The entire contents of Taiwan Patent Application No. 108114018, filed on Apr. 22, 2019, from which this application claims priority, are expressly incorporated herein by reference.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to an exercise machine, and more particularly to an exercise machine for performing stepping exercise.2. Description of Related Art[0003]A stepper is an exercise machine that increases heart rate, burns calories, and improves myocardial endurance.[0004]In the traditional stepper design, a user stands on two pedals supported by a given level of resistance. The user lifts alternating feet, as if walking up a set of stairs, so as to build muscle in legs and gluteus. The stair stepper is also a lower-impact training machine compared to a treadmill, making it useful for those with leg injuries.[0005]U.S. Pat. No. 9,566,466 discloses an exercise device for stepping exercise, the ma...
