The present invention relates to a trampoline, and more particularly, to an underground trampoline that is easy to maintain.

A trampoline is an exercise device made by connecting a thin elastic net to a metal frame with a stronger spring or jumping band. It is a device that can jump and perform aerial acrobatics on the net.

This device is known to have the effect of stimulating the growth plate in children in the growing stage, and it is also widely used as a play equipment for infants because of its effects on the development of whole-body movement and sense of balance.

However, infants who do not have sufficient sense of balance and body do not withstand the recoil of the trampoline well, so if several people run together, they may be thrown out of the trampoline and fall or get injured by hitting the frame.

Accordingly, trampolines recently installed cover the upper part of the trampoline's spring with a mat and install a safety net around the trampoline to prepare for crash and fall accidents that occur in the trampoline. There is a risk of injury.

Recently, a trampoline that is installed underground rather than on the ground has been developed. However, as trampolines are installed underground, when performing maintenance, repair, or cleaning, the mat fixed to the spring must be removed, then go down under the mat to work, and after the work is finished, the spring and mat must be installed again. There is discomfort.

In addition, the mat is worn out and frayed when used for a long time, and it is necessary to replace the worn mat in time to prevent safety accidents. There is a problem in that the replacement time is missed because it is difficult to easily determine the degree of wear of the mat with the naked eye.

The present invention has been devised to solve the above-described problems, and an object of the present invention is to provide a trampoline that is easy to maintain, repair and clean when the trampoline is installed underground.

Another object of the present invention is to provide a trampoline that can easily check the degree of wear of the mat.

By providing a trampoline can be achieved.

According to one aspect of the present invention, the spring board includes a first jump board including a plurality of first jumping bands installed across the space in one direction, and a plurality of second jump boards installed to intersect the first jumping bands. It may include a second springboard including a jumping band.

According to another feature of the present invention, it may further include a jumping mat coupled to the upper side of the spring board.

According to another feature of the present invention, the first jumpboard may further include an elastic member having one end coupled to the inner side of the frame and the other end coupled to the first jumping band.

According to another feature of the present invention, it may further include a coupling member for detachably coupling the jump plate and the jumping mat.

According to another feature of the present invention, an entry space portion open up and down may be formed between the inner corner portion of the frame and the take-off plate.

According to another feature of the present invention, it may further include a ladder installed in the entry space.

According to another feature of the present invention, it may further include a binding member for coupling the frame and the jumping mat.

According to the trampoline according to the present invention, since the entry space is formed in the inner corner of the frame, it is possible to enter the lower part of the take-off board without separating it during maintenance, repair or cleaning work.

In addition, according to the trampoline according to the present invention, when the jumpboard is worn over a long period of time, since the wire embedded in the jumping band of the jumpboard is exposed to the outside, it is possible to easily check the timing of replacement or repair of the jumping band.
