Description

Water rides {DEVICE FOR A RIPPLING}

The present invention relates to a water play equipment, and more particularly, when the gas is injected into the inside to expand and form an inflatable body of various shapes to float on the water, due to the expansion of the inflatable body, the occupant to ride inside A space is provided so that the occupant can ride on the water while the occupant is moving in the desired direction, and the plurality of inflatables can be interconnected and simultaneously move to the mutual inflated by a plurality of users. It is about playing with water at the same time.

In general, water play equipment is a device that floats a person who can not swim on the water to swim or enjoy playing, which is a tube of various shapes to inject air therein, and to inject air into the user Life jackets worn on the upper body are used in places with no depth.

In addition, water play equipment for use in water such as rivers and seas, such as rubber boats and yachts that a user boards and paddles, yachts, windsurfing boards, water skis, and motor boats that are powered by a motor, etc. The upper part of the surface of the water, and if the user tries to dive into the water to move, it has been developed in various forms, such as purchasing and using expensive equipment separately, especially in summer cool feeling and great fun Many people enjoy leisure on the water.

However, since general water leisure products are very large and expensive, and it is economically expensive for ordinary people to purchase and use them, most water leisure sports people rent and use leisure equipment on site. This too costs a lot, the reality is that only a limited number of people enjoy water leisure sports.

In addition, there was a problem that can cause a dangerous situation even when wearing a life jacket when drowned.

In addition, leisure equipment using the sphere-shaped air, which is enjoyed in the existing water, has a complicated problem of use for the individual because it is complicated to manufacture and assemble and difficult to carry and move. There was a problem that it is difficult to guarantee the safety because it is exposed to the risk of being bounced out of the sphere during the rapid rotation of the mechanism.

In addition, the ordinary water play equipment has a limitation of the number of users difficult to be used simultaneously by a large number of users, and there is a problem that a large number of people cannot enjoy simultaneously because a small number of people must use them individually.

The present invention has been made to solve the above problems,

When air is injected through the air injection unit to float in the water by using buoyancy, it expands to form an inflatable body having various shapes, and due to the expansion of the inflatable body, a space for occupants to ride therein is provided. Passengers on board can enjoy water play without moving on the water, and the occupants move in the desired direction, and a plurality of personnel can be connected to each other by interconnecting a plurality of the inflatable bodies and moving from the occupants and their own inflated bodies to other inflatables. This can be enjoyed at the same time, and by removing the air from the inflatable after using the water playground equipment, it is easy to carry and move by making the volume small, so that the individual can easily purchase and use the equipment at a low price. It is safe to enjoy water leisure without any risk of use by preventing it from being separated from inside to outside. The purpose is to provide a long play equipment.
