CONSTITUTION:This is a water leisure boat which is provided with a propeller, and slides on the surface of water, and is provided with a brake plate 4, which consists of a plate rotatable around a horizontal shaft 6 on the front end, on the bottom of the boat roughly in the center in longitudinal direction of a hull 1, a brake pedal 7, which immerses this brake plate 4 in water by pressing it down around a shaft 6, and recover means 71 and 73 for the brake plate 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-operated playground equipment with a propeller, which is usually for one passenger and slides on the water surface.

[0002]

2. Description of the Related Art Heretofore, various small and lightweight water play equipments have been proposed, and the braking action thereof is performed by decelerating the engine, so that the braking action is very weak. However, since the water play equipment has become faster due to an increase in its output, there is a demand for the development of a device capable of excellent braking for safety and various competitions.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and provides a water play equipment capable of favorably performing a braking action with a simple structure. The purpose is to do.

[0004]

SUMMARY OF THE INVENTION The present invention is a water play equipment with a propulsion device that slides on a water surface, and a plate that is rotatable about the axis of the front end is provided at the bottom of the ship at approximately the center in the longitudinal direction of the hull. The above-mentioned brake plate is provided, and the operating means for pushing the brake plate down around the axis to immerse it in the water and the returning means for the brake plate are provided.

[0005]

In the above construction, the bottom of the ship is provided with a brake plate made of a plate rotatable about a horizontal axis at the front end, and the brake plate is rotated about the axis to be submerged in water for braking. Therefore, it is possible to surely exert the braking action with a simple configuration, and it is also possible to make a sharp turn and to exert excellent exercise performance.

[0006]

1 to 3, an operating handle 2 is installed on a hull 1 of a water playground equipment at substantially the center of the hull, and a seat 20 extending in the stern direction is formed on the rear side thereof, and A foot deck 21 that opens to the stern end is formed on both sides. The hull 1 is configured to slide on the water surface by operating a propulsion device (not shown). A brake plate 4 is arranged on the bottom of the hull 1 approximately at the center in the longitudinal direction. The brake plate 4 is configured to be rotatable around a shaft 6 at its front end, and is pushed down by an operating shaft 40 to be immersed in water. Is configured. A brake pedal 7 is arranged at the front end portion of the foot deck 21 on the ship, and a person straddling the seat 20 depresses the brake pedal 7 to thereby operate the cylinder 7
1 is operated so that the brake cylinder 73 is operated by the pressure oil supplied through the oil pipe 72,
The brake plate 4 is operated by the cylinder rod of the brake cylinder 73 (which constitutes the operating shaft 40). Further, the brake pedal 7 is configured to be restored by an appropriate restoring means by releasing the stepping force.

FIG. 4 shows another embodiment of the present invention. An operating shaft 50 directly connected to a brake pedal 8 is connected to a brake plate 5 rotatably mounted around a shaft 6 at the front end, and this brake is used. The rear end of the pedal 8 is rotatably supported around the shaft 51, and an upward force is applied by the return spring 52 to raise the front end of the brake pedal 8. By stepping on the brake pedal 8 against the force of the spring 52, the brake plate 5 is directly pushed down and immersed in the water.

In each of the above-mentioned embodiments, the brake plates 4 and 5 respectively form a part of the chine or a part of the bottom of the ship, and are housed so as not to project from the bottom of the ship when they are inactive, and therefore, during normal running. No resistance. In the configuration shown in FIGS. 1 to 3, by depressing the brake pedal 7, the cylinder 71 and the brake cylinder 73 are operated to immerse the brake plate 4 in water. Further, in the configuration of FIG. 4, the brake plate 5 is directly immersed in the water by depressing the brake pedal 8. When the brake plates 4 and 5 are immersed in the water, a great resistance is generated in the boat while traveling, and a large braking force is generated. For this braking, the brakes on both sides may be simultaneously actuated to act as a brake for a sudden stop, or a sudden turn may be performed by actuating only one of them. Further, the combination of the both may be made to perform both the sharp turning and the braking. The magnitude of the braking force of the left and right braking forces at that time can be adjusted by the rotation angle of the brake plate, that is, the inclination angle.

[0009]

As described above, according to the present invention, the bottom of the ship is provided with the brake plate made of a plate rotatable about the horizontal axis of the front end, and the brake plate is rotated about the axis to be immersed in water. The braking action can be performed by means of a simple structure, the braking action can be reliably exerted, a sharp turn is also possible, and the exercise performance is excellent.
