TENSION EXERCISER WITH ELASTIC LIMIT FUNCTION
A tension exerciser with elastic limit function includes a weaving tape without stretching elasticity which is made of weaving materials and defined into a flexible elongated band pattern. The weaving tape includes a tape body, a fixed part and an operating end. The fixed part is provided with a positioning member. A handle is connected with the operating end, allowing the users to hold it for pulling. An elastic part is connected between the tape body and the operating end, so that elastic resistance occurs when holding the handle for pulling. An elastic limiter is connected between the tape body and the operating end. The elastic limiter enables the extension of the elastic part to be limited within the maximum load range, so as to prevent elasticity fatigue or even rupture of the elastic part of the tension exerciser, extend the service life and improve the operating safety.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to a tension exerciser, and more particularly to an innovative one which is designed with an elastic limit function.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
The tension exerciser referred hereto is a fitness device that is specifically designed with a fixed end, elastic section and handle, etc. When said tension exerciser is used, it is mounted onto a fixed object (e.g.: door plank, partition wall and rack body) by its fixed end, and the user could hold the handle for pulling and stretching so as to make physical exercises and realize fitness effect via the elastic resistance generated by the elastic section. Due to its comparative advantages, such as simple construction, small volume, portability and retractility over other treadmills and exercise bikes, such tension exerciser with excellent fitness effect is now widely used by many customers in a broad market.
Some shortcomings and problems of existing tension exerciser are still observed during actual applications. For example, the elastic section of conventional tension exerciser is designed with a maximum elastic stretching tolerance, or the pulling force of many users could reach said maximum elastic stretching tolerance. However, in the event of excessive force applied by the user, this will cause rapidly the elasticity fatigue or even rupture of the tension exerciser. In particular, upon rupture, the rebounding of the elastic material will possibly endanger the users. If the elastic section is under high tension state for a long period of time, elastic fatigue will be caused rapidly by excessive use, shortening the service life of the tension exerciser.
If the user intends to control the pulling force to extend the service life of the tension exerciser, it is very difficult for the user to find out the elastic setting limit of the tension exerciser and control accurately the force.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.
Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
BRIEF SUMMARY OF THE INVENTIONBased on the innovative structural design of the present invention wherein the tension exerciser with elastic limit function comprises: a weaving tape, handle, elastic part and an elastic limiter, the extension of the elastic part of the present invention could be limited within the maximum load range via the elastic limiter, so as to prevent elasticity fatigue or even rupture of the elastic part, extend the tension exerciser's service life and promoting the operating security.
The improvements brought about by this invention are as follow:
Based on the structural design wherein an adjustable member is located on the elastic limiter formed by the bending section, the stretched length and stroke of the elastic limiter could be adjusted to meet diversified user requirements.
Based on the structural design wherein a secondary handle is set onto the tape body of the weaving tape, but not connected with the elastic part and the elastic limiter for another operating mode for users, when the user holds the secondary handle for pulling, the tape body of the weaving tape is directly pulled without elastic stretching effect, to as to meet diversified user requirements.
Based on the structural design of said hook-shaped body and the second hook-shaped body, two different installation modes (with or without elasticity) could be provided to the users and adapted to the elastic part for flexible operation.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
Said tension exerciser comprises a weaving tape 10 without stretching elasticity, which is made of weaving materials and defined into a flexible elongated band pattern. The weaving tape 10 comprises a tape body 11, a fixed part 12 and at least an operating end 13. Of which, the fixed part 12 is provided with a positioning member 14 for positioning onto an object (e.g.: door plank, partition wall and rack body).
At least a handle 20 is connected with the operating end 13 of the weaving tape 10, allowing the users to hold it for pulling.
At least an elastic part 30 is connected elastically between the tape body 11 of the weaving tape 10 and the operating end 13, so that elastic resistance occurs via the elastic part 30 when the users hold the handle 20 for pulling.
At least an elastic limiter 40 is connected between the tape body 11 of the weaving tape 10 and the operating end 13. The elastic limiter 40 enables the extension of the elastic part 30 to be limited within the maximum load range, so as to prevent elasticity fatigue or even rupture of the elastic part 30.
