AI Technical Summary

Problems solved by technology

The biggest weak point of such a frame structure is located at the joint A between the two equally divided pipe fittings 10. When this point is subjected to a certain external force, the entire circular peripheral frame is likely to form a folded shape, which seriously affects its safety.
In some cases, in order to increase the strength of the circular peripheral frame, screws are fixed at the junction A of the two equally divided pipe fittings 10, so that while the strength increases, the production difficulty and manufacturing cost also increase.

Embodiment Construction

[0018] The present invention mainly includes the peripheral frame with the short branch pipe 3 at the bottom, the elastic element 8 with the bouncing surface 9 placed in the peripheral frame, the connecting pipe 4 and the foot bracket 5 placed at the bottom of the short branch pipe 3, and fixed on the short branch pipe 3 and the foot support respectively. Guard bar 7 on the support 5. The peripheral frame is composed of 3-8 sections of long outer frame 1 and short outer frame 2 alternately socketed, and short branch pipes 3 are affixed to positions close to both ends of the long outer frame 1 . The length ratio of the long outer frame 1 and the short outer frame 2 is 1.1-2:1, and the distance L between the fastening point H of the short branch pipe 3 on the long outer frame 1 and the joint A at both ends of the long outer frame 1 is 5-30 cm, the short branch pipe 3 and the foot support 5 are connected and fixed with the guard bar 7 by the hinged holding clip 6.

Abstract

A novel jumping bed as a sports apparatus is composed of a peripheral frame consisting of 3-8 long tubes and short tubes, which are alternatively sleeved, the short supporting tubes fixed to both ends of said long tubes, a jumping surface, several elastic elements arranged between peripheral frame and jumping surface, supporting feet, and connecting rods between said short supporting tube and supporting foot. It has high impact strength.

Description

technical field [0001] The invention relates to a novel trampoline, belonging to the technical field of trampoline manufacturing in sports equipment. Background technique [0002] The trampoline is mainly provided with a bouncing surface composed of multiple elastic elements inside the circular frame, and a safety fence higher than the bouncing surface of the trampoline is provided on the periphery. The frame structure usually consists of a peripheral frame, a short branch pipe, a connecting pipe, a foot bracket and Fence protection poles and other combinations. In order to facilitate manufacturing and transportation, the circular peripheral frame is usually divided into multiple sections, which are combined and connected by necking at one end. [0003] Referring to accompanying drawings 1 and 2, the frame structure of the existing trampoline is mainly a circular peripheral frame composed of multiple equally divided pipe fittings 10, and a short branch pipe 3 is fixed in th...
