Abstract

PURPOSE:To secure a sufficient strength of stability in standstill state and secure the superior movement performance in sailing by installing the foldable vanes on the both broadsides of the vessel body of a water playing device equipped with a steering mechanism at the front part, injection propulsion machine at the rear part, and a flat deck at the center part. CONSTITUTION:Vanes 20 are installed onto the both sides of the vessel body of a water playing device having a steering mechanism 7 at the front part of the vessel body consisting of a flat and slender board, water-jet type propulsion machine at the rear part, and a flat surface deck 10 at the center part. Said vane 20 is connected in foldable ways around a hinge onto the vessel body. Therefore, in standstill state, the vanes can be extended to the both sides, and a sufficient strength of stability can be provided, and in sailing, the vanes are folded and can be accommodated into the vessel body and the superior movement performance can be developed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to improvements in water play equipment, particularly to water play equipment with eyes that are lightweight and have excellent maneuverability.

(Prior Art) Recently, various types of water play equipment have been proposed that have a small and lightweight boat body, have a propulsion device, and glide on water. In these devices, the hull is constructed to be large enough to have sufficient buoyancy and restoring force even when the boat is stationary with people on board, so the maneuverability during sailing is hindered accordingly. become.

In other words, because the boat is constructed to have sufficient restoring force when stationary and when cruising at low speeds, it is not possible to tilt the hull and turn into sharp corners when cruising at high speeds, making it difficult to make sharp turns like water skiing. The disadvantage is that you cannot enjoy slalom.

(Objective of the Invention) This invention was made against this technical background, and provides a boat with sufficient buoyancy and restoring force when stationary, and the ability to freely tilt the hull when cruising at high speed. To provide a water toy equipment that enables the user to exercise freely and exhibit excellent exercise performance.

(Structure of the Invention) The present invention is a water play equipment having a steering mechanism in the front part of the boat body made of a flat and elongated board, a water jet type propulsion device in the rear part, and a deck with a flat surface in the center part. There are wings on both sides of the body, and these wings are rotatably connected to the hull around a hinge, so they have sufficient restoring force when stationary, and have excellent maneuverability when sailing. is also excellent.

(Embodiment) In FIGS. 1 and 2, a boat body 1 made of a flat and elongated board has a flat deck 10 on which a person rides formed in the center, and an engine casing 9 is covered at the rear. A powered engine 90 is disposed, and a steering device, which will be described later, is formed in the front portion. A passage for water to pass through is formed below the engine 9.0, and an impeller rotated by the engine 90 is arranged therein to suck water under the bottom of the ship into the passage and jet it out at high speed from the outlet. This creates a propulsive force.

A water exhaust nozzle 6 is provided at the outlet of this passage to rotate the boat body 1 by discharging the water flow sent out from the passage in an arbitrary direction. This water exhaust nozzle 6 is configured to be able to swing around a shaft 60 that is vertically attached to the hull 1, and is configured to be able to swing by means of steering cables connected to both sides of the shaft.

The steering device includes a steering handle 7 supported by a support 12.
A steering leg rod 70 connected to the steering handle 7 extends in the longitudinal direction of the boat body 1, and the steering rod 70 passes through the support 12 and is rotatably held around its axis. A floating body 77 is attached to the base end of the stair leg rod 70, thereby preventing the steering handle 7 from sinking into the water when the boat body 1 overturns.

The steering handle 7 is located on a deck 10 in the center, and the occupant stands on the deck 10 and grasps the steering handle 7, thereby supporting his body and steering the vehicle.

Wings 2 are rotatably coupled to both sides of the hull 1 by hinges 4 and 44. Hinge 4 is shown in Figures 3 and 4.
As shown in the figure, opening and closing means are provided. That is, a spring 40 is attached to the center of a pair of members 41 and 42 constituting the hinge 4, so that the wing 2
A force is applied so that χ points upward (perpendicular to the hull 1). The member 41 also has a pair of holding members 80.
is attached, thereby movably holding the U-shaped actuating rod 8. A block 5 is fixed to the member 42, and the block 5 has holes 51 and 52 that are perpendicular to each other.
is formed, and the actuating rod 8 is fitted into either the hole 51 or 52, so that the state shown in FIG.
4) or in the state shown in FIG. 4 (H2 is parallel to the hull 1).

Also, only the spring 40 is attached to the hinge 44! ! ! A force is applied such that 2 is perpendicular to the hull 1.

5 and 6 show another embodiment of the present invention, in which a fixed 9i20 and a movable m21 are provided on both sides of the hull 1, and the movable wings 21 are connected to the hull 1 by the hinge. 4
The blades 21 are connected by the hinges 4, so that the blades 21 can rotate around the hinges 4 between a vertical state and a horizontal state as shown in FIG.

In addition, hinge 4! Various other types of l@ can be used as long as they do not cause ridges in the configuration of the above embodiment and can make the blades horizontal and vertical.

In the above configuration, first, as shown in FIGS. 1 and 4, with the blade 2 in a horizontal state, the actuating rod 8 is inserted into the hole in the block 5.
1 is fitted and fixed, the boat body 1 is floated on water in that state, and a person gets on the deck 10. In this state, the boat 112 also acts as a floating body and has a wide hull, so the buoyancy and restoring force are large, and the boat 112 can stand on the deck 10 stably. Then, by gripping the steering handle 7 and starting the engine, the vehicle sails on the water.

As the cruising speed increases, the buoyancy force increases due to the dynamic pressure of the water, so not only does the buoyancy force t from the wings 2 become unnecessary;
The large surface area of the hull in contact with the water creates a lot of resistance, and it is also a national problem to tilt the hull. Therefore, by removing the operating rod 8 from the state shown in FIG. 4, the blade 2 is brought into a vertical state by the force of the spring 40, and the operating rod 8 is fitted into the hole 52 of the block 5 as shown in FIG. let As a result, the wings 2 are separated from the water surface, and the boat can sail only with the hull 1. Therefore, the area in contact with water is reduced, reducing running resistance, and the occupant can turn at a fish angle by tilting the hull 1 together with his or her body. In other words, you can enjoy slalom like Niski on water. When tilting the hull 1, the crew member must use the steering wheel 7.
You can support your body by holding on to it. If the hull 1 overturns while sailing, the crew members can raise the hull 1, spread the wings 2, and get on the boat, and use the following operations to move to the running position. .

Note that the operation and effect of the embodiment -b of FIG. 5 are the same as those described above, and by rotating the movable wing 21, it is possible to meet the respective requirements in the stationary state and the cruising state.

(Effects of the Invention) As explained above, in this invention, wings are provided on both sides of the hull, and the wings are rotatably connected to the hull around the hinge, so that the wings can be fully restored when in a stationary state. It is designed to have great power and exhibit excellent maneuverability when sailing.
