Abstract

Disclosed is a single-driving dual-directional operation device for fitness equipment, including a driver assembly, a first motion assembly, and a second motion assembly. The first and second motion assemblies respectively include first and second one-way bearings that are operable in first rotational direction and opposite second rotational direction respectively to allow the first and second motion assemblies to selectively get in driving engagement with the driver assembly to be respectively driven thereby to rotate in the first and second directions. Thus, when the driver assembly is put in operation selectively in the first and second directions, rotation motion is respectively induced in the first and second motion assemblies via the first and second one-way bearings in an interference-free and independent manner.

Description

BACKGROUND OF THE INVENTION

[0001] (a) Technical Field of the Invention

[0002] The present invention relates to driving of fitness equipment, and in particular to a driving device that uses a single driving source to operate in two different modes or exercise functions in an interference-free and independent manner so that a user's need of different exercise modes can be satisfied

[0003] (b) Description of the Prior Art

[0004] To cope with the substantial reduction of exercising sites and time that are available for modern people, a variety of exercising device or fitness equipment is available in the market. Unless no driving structure is adopted, most of the currently available fitness devices have effect a single type of exercise or training. Alternatively, the fitness device may achieve different type of training by altering the operation mode thereof For example, a treadmill comprises a chassis having two ends to which front and rear cylinders are respectively mounted and a tre...
