<<Operation>> The power propulsion type leisure vehicle of the present invention can be enjoyed in the following manner.

First, the floating vehicle 1 is floated on the water surface of the aqua leisure facility. The floating vehicle 1 itself is in an upright posture while floating on the water surface.

Next, the player A rides on the floating vehicle 1 in an upright position and either straddles it or stands up. As a result, the floating vehicle 1 becomes unstable and prone to overturn, so the player A maintains his/her balance to avoid falling over and enjoys the game.

Then, when the player A opens the propulsion operation valve 4, the pressurized gas stored in the gas cylinder 2 operates the pressurized gas-operated propulsion device 5, and the floating vehicle 1 is propelled by the propulsion force. Even when floating vehicle 1 is being propelled, it is unstable and tends to overturn, so player A
They enjoy keeping their balance and propelling themselves forward without falling over.

You can laugh when you fall while trying to keep your balance, applaud when you are able to move forward, and have fun with everyone around you.

Also, you can compete to see how far you've progressed, make fun of people around you or shake them to make them lose their balance, or fight each other in one-on-one combat.
You can have fun together with everyone in a variety of ways.

<<Effects of the Invention>> The power propulsion water leisure vehicle of the present invention can be used and enjoyed as described above, and has the following effects.

(b) You can enjoy the vehicle by propelling it while maintaining balance so that it does not fall over, so you can fully enjoy the vehicle without propelling it at high speeds, and eliminate the risk of colliding with other objects at high speeds and causing a serious accident. .

(b) Since it eliminates the risk of major accidents caused by collisions at high speeds, it can be used satisfactorily and safely in aqua leisure facilities such as beaches, leisure pools, and leisure hot springs where swimmers are present.

C) It can be enjoyed in a safe manner at low speeds, and it can be operated very easily by simply opening and closing the propulsion control valve, so anyone from children to the elderly can easily enjoy it.

D. Even when the floating vehicle falls over, the problem of the gasoline for the conventional engine contaminating the water surface does not occur at all.

Furthermore, the conventional product never becomes inoperable due to water intrusion.

E. Compared to conventional engines, the gas cylinder of the present invention is much lighter, so floating vehicles can be made smaller and have less buoyancy.

Since the water leisure vehicle of the present invention uses a gas cylinder instead of the conventional engine, manufacturing costs can be significantly reduced, there will be almost no breakdowns, and maintenance will be much easier.

<<Example>> Hereinafter, an example of a power propulsion type water leisure vehicle according to the present invention shown in the drawings will be described.

FIGS. 1 and 2 show a first embodiment of the power-propelled water vehicle play equipment according to the present invention,
This power propulsion type water vehicle play equipment has a cylinder storage part 1a formed in the lower part of a floating vehicle 1 made of foamed plastic or other lightweight material formed in the shape of an animal (a horse in the figure). A propulsion control valve 4 connected to the gas cylinder 2 through a pipe 3 is arranged on the upper part of the floating vehicle 1 so as to house a gas cylinder 2 filled with a pressurized gas consisting of harmless gas such as air, nitrogen, carbon dioxide, etc. Further, a pipe 6 is guided from the propulsion operation valve 4 to the rear of the floating vehicle 1, and an injection nozzle 5a is installed at the rear end of the pipe 6.
A pressure gas operated propulsion device 5 consisting of the following is installed.

The floating vehicle 1 is formed in such a shape that the center of gravity G with a person on it is higher than the center of buoyancy H so that it is easy to fall over while floating on the water surface with a person on it.

The propulsion control valve 4 is incorporated into, for example, a handle 12 so that it can be operated from the outside of the floating vehicle 1 while a person is riding on the floating vehicle 1. Also,
The propulsion operation valve 4 may be of an open/close switching type or an opening amount adjustable type.

The gas cylinder 2 has a valve 2 for adjusting gas pressure.
a and a gas filling port 2b for filling the gas cylinder 2 with pressure from the outside. This gas cylinder 2 may be of a replaceable type in addition to the illustrated filling type. Moreover, the pressure gas filled in this gas cylinder may be compressed gas or liquefied gas.

By using a spring or other mechanism to close the valve when it is not operated from the outside, if the player falls and takes his or her hand off the operating part, the propulsion device will stop and the floating vehicle will move automatically. You can prevent it from running on its own.

Note that the floating vehicle 1 does not necessarily need to be provided with a handle, as long as the propulsion operation valve 4 can be operated from the outside.
