1. Field of the Invention
The present invention relates to an exercise apparatus, especially to a rope pulling exercise apparatus with variable resistance.
2. Description of the Prior Art(s)
With progress of the society, people's activities are more and more depending on machines and technical products. The people without regular and enough exercises have reduced muscle strength and mass. Therefore, the people nowadays should have to pay attention to exercise.
Diseases of affluence occurring on the modern people are relevant to if the people exercise regularly. Mentally, exercise is helpful in reducing stress and tiredness. As the people are in good moods, the people are also good in interpersonal relationships. To have habits of exercise allows the people to have high self-esteem and have confidence on themselves. Physically, exercise is helpful in increasing metabolism, improving cardiovascular health, reducing incidence of heart disease and apoplexy, and lowering cholesterol and blood pressure.
Moreover, through weight training, muscles can be trained to support bones and joints and to protect important organs of a human body, so the people become strong and health. Since doing exercises is not only good for mental and physical health but also protects a human body, in urban areas with high population density, the people go to exercise in fitness clubs, sports centers or gymnasiums. However, since fitness equipments in the fitness clubs, the sports centers or the gymnasiums are almost the same, the people might feel bored over time, and lose their desire to keep on exercising.
To overcome the shortcomings, the present invention provides a rope pulling exercise apparatus with variable resistance to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONThe main objective of the present invention is to provide a rope pulling exercise apparatus with variable resistance. The rope pulling exercise apparatus has a main supporting frame, a rotary cylinder assembly, a rotary wheel, a driving device and a resistance generating device. The rotary cylinder assembly is pivotally mounted on the main supporting frame and has a pull-rope wrapped around a rotary cylinder. The rotary wheel is pivotally mounted on the main supporting frame. The driving device is disposed between the rotary cylinder and rotary wheel and has a driving wheel coaxially mounted on the rotary cylinder, a driven wheel coaxially mounted on the rotary wheel, aligning with the driving wheel and being smaller than the driving wheel in radius, and a transmission belt mounted around the driving wheel and the driven wheel. The resistance generating device is disposed adjacent to a peripheral surface of the rotary wheel and selectively resisting rotation of the rotary wheel.
When a user pulls the pull-rope of the rotary cylinder assembly, the rotary cylinder rotates accordingly and the rotary cylinder rotates the rotary wheel through the driving device. The resistance generating device applies rotational resistance to the rotary wheel. Thus, the user can pull the pull-rope back and forth to train himself The rope pulling exercise apparatus provides the user one more option on choosing fitness equipments, and increases the user's desire on exercising. Moreover, as the driving wheel is larger than the driven wheel in radius, the rope pulling exercise apparatus provides effective fitness effect.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The rope pulling exercise apparatus as described has the following advantages. The resistance generating device 50, 50A, 50B is disposed around the rotary wheel 30, 30A and applies the adjustable rotational resistance to the rotary wheel 30, 30A. When the user pulls the pull-rope 23 of the rotary cylinder assembly 20, the rotary cylinder 21 rotates accordingly and the rotary cylinder 21 rotates the rotary wheel 30, 30A through the driving device 40. The resistance generating device 50, 50A, 50B applies the rotational resistance to the rotary wheel 30, 30A. Thus, the user can pull the pull-rope 23 back and forth to train himself. The rope pulling exercise apparatus provides the user one more option on choosing fitness equipments, and increases the user's desire on exercising. Moreover, as the driving wheel 41 is larger than the driven wheel 42 in radius, the rope pulling exercise apparatus provides effective fitness effect.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
