Safety Fence and Protection Pole Connection Apparatus for Trampoline

Abstract

A kind of safety fence and protection pole connection apparatus for trampoline, belonging to the manufacture technique field for trampoline subassembly. It comprises a fence protection stem; an outside frame with a short pole attached its bottom; a foot supporter located under the short pole; wherein the fence protection stem, short pole and foot supporter are clamped down together by hinge style embrace clamps separately. The hinge style embrace clamp comprises a clamp body with a hole for protection hole and a hole for tube, a hinge located the end of the clamp body, a clamping device located the open part of the embrace clamp. The present invention provides a safety fence and protection pole connection apparatus for trampoline; it has reasonable design, enough structure strength for the frames, nice orientation for the fence protecting stems, and conveniences in the assembly and manufacture.

Description

CROSS REFERENCE TO RELATED PATENT APPLICATION This application claims the priority benefit of a Chinese patent application No. 200520013345.7, filed on Jul. 14, 2005. FIELD OF THE INVENTION [0001] This invention involves a kind of safety fence and protection pole connection apparatus for trampoline, belonging to the manufacture technique field for trampoline subassembly. BACKGROUND OF THE INVENTION [0002] Usually, a trampoline has a circular frame, a bounce surface constituted by multiple spring components is located in the circular frame. A safety ring fence that is higher than the bounce surface is established on the outer circle of the bounce surface. The safety fence includes fence protecting stems and a ring fence. Therefore, users can play jumping on the trampoline, avoid falling outside in result harm. [0003] The safety fence always is set around the trampoline. The most convenient way is that connect the fence protection stem with the foot supporter. However, the conventiona...

AI Technical Summary

Benefits of technology

[0005] The purpose of the present invention is to provide a safety fence and protection pole connection apparatus for trampoline, it has reasonable design, enough structure strength for the frames, nice orientation for the fence protecting stems, and conveniences in the assembly and manufacture.

[0012] The present invention uses the hinge style embrace clamp to clamp down the fence protection stem with the short pole and foot supporter. The design is reasonable. Therefore, the assembly of the fence protection stem and short pole is fast and the orientation is better. Since the join of the fence protection stem and the short pole is clamped down by the hinge style embrace clamp, the stress area becomes two orientation circular surfaces rather than points. By this means, the combining force for fence protection stem and foot supporter is increased greatly. Comparing the present invention with the prior art, the new connection apparatus improves heavy and complicated operations caused by the U style clamp and avoids the disadvantages of swaying, slipping and the collapse of the combination of structures. In the mean time, the new designs of the screw and nut style clamping device, eccentricity handle style clamping device and turn pucker handle style clamping device satisfy the requirements by the new trampolines with different style and scale. When dismantlement of the ring fence, the hinge style embrace clamp can clamp on tubes. Thus, people do not worry loss of it.

Problems solved by technology

However, the conventional connecting type is inconvenient and lacks strength in structure, etc.

This kind of combining structure for the fence protecting stems 1 brings inconvenience in the assembly, and causes the ring fence difficult to fit the outside frame 6.

Consequently, to the conventional connection apparatus its design is not reasonable, its strength of structure is weak.

Thereby, its frames always shake and skid when people play on the conventional trampoline.
