CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of China patent application No. 201410605158.1, filed on Oct. 31, 2014. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.

TECHNICAL FIELD OF THE INVENTION

The invention belongs to the technical field of fitness and entertainment facilities, specifically to a trampoline with a guardrail cushion mechanism.

BACKGROUND OF THE INVENTION

A trampoline is sports equipment which helps train the balance, response capability, dynamic vision and muscle softness of a human body. Meanwhile, the moderate shaking by the bouncing motion helps the development for young persons. Therefore, the trampoline is an entertainment and leisure activity for all ages. A conventional trampoline basically consists of the following components: a mat, a trampoline frame, a flexible component connecting the mat with the trampoline frame, a shield covering part of the trampoline frame and the flexible component, as well as a leg component connected with the trampoline. In order to improve safety, some trampolines also include a safety net preventing the user from falling off from the trampoline during use.
However, the trampoline of the current market has the following problems: (1) small elastic range, large impact on the human body, and backward damping functions; (2) a stiff guardrail structure, small bearing capacity, and poor bounce effect; (3) the lack of an electronic competition vocal device and thus low entertainment.
In order to address the problems of small elastic range and backward damping function, Invention Patent CN102000411A discloses a fence support structure of a trampoline. It is an improved connection structure between the trampoline and the fence. It is characterized in that it includes a main body of the trampoline, a plurality of support rods and a fence. The main body of the trampoline includes a bounce area in which bouncing motion is carried out. A support rod stands upright along the outer periphery of the main body of the trampoline. The top ends of the support rod are respectively provided with a cushion device and connected with a support frame through the cushion device. The top end of the support rod, in the direction toward the center of a bouncing area, is bent and forms a bending section and an end connected with the cushion device toward the bouncing area. Thus, the cushion device may obtain better stretching and cushion effects.
In order to solve the problems of a stiff guardrail structure, small bearing capacity and poor bouncing effect, Invention Patent CN201105113Y discloses a fence structure of a trampoline. A fence structure of the trampoline includes a main body of the trampoline and a fence provided at the outer periphery of the main body of the trampoline. The fence is connected with the main body of the trampoline through a fence rod. It is characterized in that the fence rod includes a rod body connected with the main body of the trampoline and a connection base at the top end of the rod body. A hook is provided on the connection base. The hook is connected with the fence rod through a flexible body. One end of the flexible body is fixed in the hollow rod body, and the other end passes through a port on the rod body and a through hole on the connection base and then is connected with the hook. Therefore, it may make the fence freely stretch and cushion the impact force on the fence.
