BACKGROUND OF THE INVENTION

1) Field of the Invention

The invention herein relates to a physical fitness-use trampoline structure in which the user can, according to different positional exercise requirements, directly utilize the rotative twisting resiliency and differently orientated placement capabilities of the physical fitness-use trampoline for producing various physical fitness approaches and thereby achieve the appropriate physical fitness exercise performance.

2) Description of the Prior Art

In currently utilized physical fitness trampolines (as shown in FIG. 1), the trampoline consists an upper seat 1 of a certain thickness and resiliency, a lower base 2 of appropriate thickness, and a compressed spring 3 of a certain height. As indicated in FIG. 2, the drawing that illustrates usage, when the user wants to utilize the trampoline for physical fitness exercises, the user stands directly on top of the upper seat 1, the bodily weight moving upward and downward causing the trampoline compressed spring 3 to simultaneously produce a compressive and decompressive action to achieve the exercise objectives.

As such, the said prior art structure has the following drawbacks: 1) The compressed spring 3, the two extremities of which are conjoined between the upper seat 1 and the lower base 2, has a certain height and when the user standing on the trampoline upper seat 1 does an up and down bouncing exercise and the bodily center of gravity is biased, then the compressed spring 3 at the lower extent of the upper seat 1 is subjected to unequal force, causing the user to fall off due to bodily center of gravity instability (refer to FIG. 2). 2) Since the trampoline consists of an upper seat 1 and a lower base 2 conjoined to the two extremities of the compressed spring 3, the trampoline is only capable of up and down bouncing exercises and utilization is limited to only a single exercise that easily becomes uninteresting to the user. 3) The trampoline only has a single exercise capability and when the user desires other bodily position exercise, different exercise equipment must be additionally purchased, easily resulting in the wasting of money by the user.

In view of the said drawbacks, the applicant of the invention herein conceived of a thoughtful and original idea that following extensive design and investigation as well as repeated sample testing and numerous refinements culminated in the introduction of the invention herein.

SUMMARY OF THE INVENTION

The primary objective of the invention herein is to provide a physical fitness-use trampoline structure in which flexile elastic members are angularly arrayed at equal intervals apart to conjoin two frame members into a single structural entity to thereby produce an appropriate twisting resiliency such that the user can, according to different position exercise requirements, utilize the rotative twisting resiliency and differently orientated placement capabilities of the physical fitness-use trampoline for producing various physical fitness approaches and thereby achieve multiple efficacy physical fitness exercise performance.

Another objective of the invention herein is to provide a physical fitness-use trampoline structure in which the flexile elastic members are angularly arrayed at equal intervals apart and conjoined to the frame members and as a result have balanced twisting resiliency such that after an upper cover body and a circular guard strip are assembled to the two ends of the physical fitness-use trampoline, when the user stands on the upper cover body and does up and down bouncing exercise, the user does not hazardously fall off due to bodily center of gravity biasing.

Yet another objective of the invention herein is to provide a physical fitness-use trampoline structure in which the physical fitness-use trampoline provides for users, according to different physical fitness position requirements, to directly utilize the rotative twisting resiliency and differently orientated placement capabilities to produce various physical fitness approaches and without necessitating additional purchases of different physical fitness equipment such that the user does not end up wasting money.

Still another objective of the invention herein is to provide a physical fitness-use trampoline structure in which the frame members conjoined by the elastic members are wrapped in a suitably thick surrounding layer such that when the physical fitness-use trampoline is utilized horizontally by the user, this enables the physical fitness-use trampoline to smoothly roll forward and backward and, at the same time, without the floor generating frictional wear to achieve the objectives of waist, abdominal, and back section exercising.
