Description

House Type Trampoline

The present invention relates mainly to a trampoline that can be of interest to infants and children as an exercise, and more particularly, it relates to a house-type trampoline in which a ceiling is installed so that it can be opened and opened at the same time as a safety net is wrapped around the edge of a normal trampoline. will be.

Trampoline is equipped with a stepping board bound by an elastic body such as a spring in a basic frame having a predetermined height. made to be able to

These trampolines can be used in indoor spaces as well as playgrounds because they can provide fun to growing children and at the same time improve the flexibility or balance of the body, and also give an exercise effect to adults. there is.

However, since the repulsive force of the elastic body acts differently depending on which part of the stepping board is stepped on to jump, the existing trampoline loses its center of gravity and falls easily and is injured.

In relation to such a mechanism, in the case of "trampoline holder" shown in Korean Patent Application Laid-Open No. 2008-0066183, a cross tube, a support tube, a connecting sleeve, etc. can be mutually assembled to replace the conventional assembly method, A locking device and a connecting sleeve are combined to improve the safety of the trampoline in use, as well as assembling and disassembling it so that it can be easily stored after use.

However, there is a disadvantage in that it is merely a connection sleeve for binding the transverse pipe and the support pipe to each other, and the elastic member such as a spring is exposed as it is, and there is a high risk of injury to the user.

In addition, in Patent Publication No. 2014-0013458, a piezoelectric element is installed on the bottom surface of a conventional trampoline so that kinetic energy can be converted into electrical energy, and at the same time, a storage battery for storing this electrical energy is installed. There is a way to produce eco-friendly electricity while having fun, but in this case, it was mainly designed to be used in the form of children's play equipment, so it was difficult to realize electricity generation realistically.

On the other hand, in the case of the "iron rod for jumping play" disclosed in Patent Registration No. 0666280, by adding an iron rod to the frame constituting the main body of the trampoline, not only the jumping movement but also the iron rod movement has the effect of ensuring stability by the safety fence. It is configured to be able to

However, since the bracket for fixing the iron bar is integrally formed with the frame itself, when jumping from the jump on the frame, the shaking of the iron bar is so severe that other children cannot play with the iron bar properly, and the safety fence is not attached to the frame. It surrounds the entire perimeter, so if a child who enjoys jumping rather gets caught or bumps into it, it can cause a greater safety accident.

Moreover, since most trampolines are configured so that jumping can be performed indoors, their use is extremely limited.
