Problems solved by technology

The trampoline in the prior art has the following defects: 1. The frame volume of the trampoline is relatively large, so when the manufacturer produces the trampoline product, each assembled trampoline will have a considerable volume, and not only the finished product will be stored in the factory. It will occupy the limited space in the factory, and it will also increase the transportation cost when it is exported. Moreover, regardless of the store for exhibition or individual users, the trampoline will occupy a considerable indoor space when it is not in use.
However, this kind of protective pad needs to increase the cost of the trampoline; increase the assembly time, and at the same time, due to the elastic deformation of the spring, the protective pad is tightly covered when not in use, but after the elastic deformation of the spring, the protective pad will deviate, causing The spring is exposed due to uneven coverage, which may increase the incidence of safety accidents
3. Because the spring is used as the elastic part and the protective pad is used to cover the laying, the effective use area of ​​the trampoline is greatly reduced, and the existence of the spring limits the actual jumping space of the trampoline
The elastic cloth of the trampoline in the prior art has problems such as short service life and poor elasticity uniformity of the cloth surface.

Abstract

The invention provides a long-life elastic uniform bedjump. The bedjump comprises a frame, an elastic trampoline cloth and a protective net; the frame comprises a bottom frame and legs installed on the lower portion of the bottom frame. The elastic bedjump cloth is of a double layer structure, one layer is elastic material strips made of nylon fibers, the other layer is material strips made of cellulose fibers, the two layers are combined through a polymer elastic layer; the nylon elastic material strips are subjected to anti-ageing treatment.

Description

technical field [0001] The invention belongs to the field of trampolines and elastic trampoline cloth used for trampolines. Background technique [0002] In 2009, "Bedjump" quickly became popular on the website, translated into Chinese as "trampoline" or "jumping bed". There are many fans who love this sport all over the world. Enthusiasts usually choose a springy bed, jump up, and make various movements in the air. The trampoline is mainly provided with a fabric tensed by a plurality of springs in the frame supported by the foot stand, for the user to stand on the bouncing surface and continuously bounce for interesting sports. The trampoline in the prior art has the following defects: 1. The frame volume of the trampoline is relatively large, so when the manufacturer produces the trampoline product, each assembled trampoline will have a considerable volume, and not only the finished product will be stored in the factory. It will occupy the limited space in the factory...
