Exercise machine with adjustable tension

Abstract

An exercise machine has an exercise machine body, and the exercise machine body is combined with a soft pad, such that a user can put both knees onto the soft pad for abdominal or hip exercises. The exercise machine body has a base, an upper cover, an elastic line, a sliding set, an adjusting device and an adjusting screw.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an exercise machine with adjustable tension, and more particularly to an exercise machine which can provide different levels of pulling force training for a user.[0003]2. Description of the Related Art[0004]As the quality of life improves, people are eating increasingly unhealthy foods, which is leading to increased cholesterol levels, hypertension, heart disease and other cardiovascular diseases. As the pace of life increases, people have less time to devote to sports and fitness, with the result the waistlines increase even as people become more listless. In view of this, given the need to conserve space and provide convenience for the user, exercise equipment that can be easily stored when not in use is desired. An example of such equipment is push / pull exercise machines.[0005]Please refer to FIG. 8. A typical pulling exercise machine comprises two tubes 81 forming a frame 80, a separ...

Benefits of technology

[0010]In order to provide different tensions, the knob of the exercise machine in the embodiment of the present invention can be adjusted to rotate the adjusting screw; since the adjusting device is limited by the limiting edge and the extending wings, the rotational movement is converted into horizontal movement which acts on the elastic line and changes its tension. When the adjusting device is moved forward, the distance between the adjusting device and the first bar is increased, which stretches the elastic line and increases its tension; therefore, the user needs to put more strength into pushing the sliding set. On the other hand, when the adjusting device is moved backward, the distance between the adjusting device and the first bar is shortened, which looses the elastic line and decreases its tension; therefore, the user can push and pull the sliding set easier. Without changing the exercise machine and the elastic line, the user can obtain different levels of training, which is very economical.

[0011]With the above-mention embodiment structure, the following benefits can be obtained: 1. By rotating the adjusting screw to drive the adjusting device to move horizontally to change the tension providing by the exercise machine, the elastic line does not need to be changed, which is suitable for various training regimens. 2. The embodiment structure for an exercise machine is also simple, which is inexpensive and easy to assemble.

Problems solved by technology

As the quality of life improves, people are eating increasingly unhealthy foods, which is leading to increased cholesterol levels, hypertension, heart disease and other cardiovascular diseases.

As the pace of life increases, people have less time to devote to sports and fitness, with the result the waistlines increase even as people become more listless.

However, the tension of the elastic line 86 is not adjustable, and when the user wants to exercise using different tension strengths, he or she must change the elastic line 86 or even buy a different exercise machine, which can be expensive.
