Mechanism Using a Single Power Source to Provide Two Exercising Functions for a Physical Exerciser

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...

Benefits of technology

[0008] The primary purpose of the present invention is to provide a single-driving dual-directional operation device for fitness equipment, which operation device uses a single driving source to generate or perform two different exercise operations so as to add value to the fitness equipment.

[0009] To achieve the above objective, the present invention provides a single-diving dual-directional operation device comprising: a chassis; a driver assembly mounted on the chassis and comprising a motor; a first motion assembly comprising a first shaft mounted to the chassis and a first transmission roller mounted to the shaft and in driving coupling with the motor, a first transmission cylinder being rotatably mounted to the first shaft, a first one-way bearing being arranged and coupled between the first transmission roller and the first transmission cylinder, the first one-way bearing being operable in a first direction; and a second motion assembly comprising a second shaft rotatably mounted to the chassis and in driving coupling with the first transmission roller of the first motion assembly, a second one-way bearing being mounted to the second shaft to couple a second transmission roller to the second shaft, the second one-way bearing being operable in a second direction that is opposite to die first direction of the first one-way bearing, the second shaft being in diving coupling with a driving shaft that is rotatably mounted to the chassis via the second one-way bearing. Thus, with the above arrangement, a fitness device in which the present invention is embodied uses operations of the driver assembly in the first and second directions to respectively drive a transmission cylinder of a first exercising portion and a driving shaft of a second exercising portion to selectively effect two different exercising modes in an interference-free and independent manner. Consequently, the effectiveness of exercising can be enhanced, the costs of installation and maintenance are reduced, and economic values are increased.

Problems solved by technology

Purchasing two different fitness devices to perform different exercise functions or combining an additional driving source to an existing device, such as a treadmill, to achieve two different types of training or exercise operations both are costly for general consumers and require more space for the increased total volume of the fitness device(s).

Also, increase the number of driving sources also give more potential risks of handling malfunction or broken devices.

As a result, the two solutions mentioned above are both inefficient in both economics and market competition.
