2. Description of the Related Art Conventionally, there are marine sports such as surfing, unsurfing, and jet skiing, which are performed in the sea. These marine sports are performed using waves, wind, or an engine.

[0003]

[Problems to be solved] Of these, for example, surfing uses waves, so in countries such as Japan where there are no large waves, it is not possible to fully enjoy surfing, and jet skis are equipped with engines etc. Since there is a high unit price for each unit, there is the drawback that consumers cannot comfortably do it.

On the other hand, since windsurfing is a sport that uses wind, it can be enjoyed even in places with few waves, such as Japan, but in itself it is large.
It has the drawback of being difficult to carry and not very fast.

Therefore, an object of the present invention is to provide a marine sports tool which can be enjoyed comfortably even in the absence of waves, is easy to carry, and can enjoy a sense of speed to some extent. Another object of the present invention is to provide a marine sports tool whose operation is easy. Furthermore, it aims to provide a safety tool for marine sports.

[0006]

In order to achieve the above-mentioned object, the present invention is a moving body on the water including a floating body capable of floating on the water, a wing, and a supporting rope for supporting the wing. The supporting ropes originate from the levitation body and are attached to both side ends of the wing in pairs.

It is preferable that the floating body is provided with a pulley, and the supporting rope is connected from one side end of the wing to the other side end of the wing through the pulley. It is preferable that the supporting rope is configured such that each length from the floating body to both side ends of the wing is constant, and further, a steering rope is attached to both side edges of the wing.

It is preferable that a part of the steering rope is slidably provided in an inner hole formed in the supporting rope, and a pipe is provided at an inlet / outlet port of the inner hole. Is preferred.

Then by pulling one of the supporting ropes,
The wings are tilted, and as a result, the water vehicle can be turned.

Since the steering rope is provided in addition to the supporting rope, pulling the steering rope causes an imbalance such that the wing twists, and as a result, the movable body on the water can be turned. In this case, since the lengths of the supporting ropes are equal to each other, the wing is automatically returned to its original even state by releasing the pulling of the steering rope.

Further, since the steering rope can slide inside the supporting rope, the supporting rope and the steering rope are not entangled with each other, and the air resistance can be reduced. Further, by providing a pipe at the entrance and exit of the inner hole, the supporting rope can slide smoothly in the inner hole. Furthermore, when both the left and right control ropes are pulled at the same time, the wings tilt in either the front or back direction, and the moving speed of the water vehicle can be controlled. Further, by providing the steering rope with a handle, the operation of the steering rope becomes easy.

Further, by constructing the wing, the supporting rope, or the steering rope from either synthetic resin or synthetic fiber, it can float on the water, and as a result, for example, once while moving on the water, Even if the wind stops, it can be moved again immediately when the wind blows again. In addition, by adding air to the wing, this effect is enhanced.

Further, by providing the control means for controlling the force received from the blade, the moving speed of the moving body on the water can be changed and the movement can be stopped suddenly.

Is attached. The inside of the blade 14 is hollow, and first and second support members 32 and 34 are embedded in the hollow as described later. The air in this cavity can be evacuated from the wings 14. The blade 14 is made of a flexible synthetic fiber or a synthetic resin such as a plastic sheet.

FIG. 3 is a front view of the blade 14, and as shown in the figure, the blade 14 is formed in a semicircular shape when viewed from the front. FIG. 4 is a sectional view taken along line IV-IV in FIG. 3, and as shown in this figure, the tip end portion 36 of the blade 14 is formed in a tapered shape. Further, the rear end portion 38 of the blade 14 is formed to be rounded, and the first support material 32 is internally provided along the front shape (semicircular shape) of the blade. The first support member 32 tapers toward both side ends 16 of the blade (see FIG. 5). A second support member 34 is attached from the first support member 32 toward the tip portion 36, and a plurality of the second support members 34 are arranged in parallel in the direction of the first support member 32. Further, the second support member 34 is formed in a tapered shape along the shape of the blade 14.

The support rope 18 is composed of one rope in the present embodiment, and is connected from the right end 16 of the wing on the water moving body through the pulley 26 to the left end 16B. The supporting rope 18 is made of synthetic resin or synthetic fiber, for example, polyethylene. This polyethylene has low ductility and low frictional force, and has the property of floating in water.

Next, a method of using this embodiment will be described. The operator 22 puts on the water skis 20, 20 and attaches the waist mounting portion 24 to the waist of the operator 22. Next, the pilot 22 stands on the water toward the windward and waits for the wind to blow. When the wind blows, the wind blows the central portion 2 of the wing.
At 8, the wing 14 advances due to the wind force. As a result, the operator 22 also advances through the supporting ropes 18. Next, when the operator pulls the supporting rope 18 on the right side,
The support rope 18 on the left side is raised via the pulley 26, so that the wing 14 leans to the right side and the body turns to the right side.
Conversely, when the left support rope 18 is pulled, the right support rope 18 rises, and as a result, the wings 14 tilt to the left,
The body turns to the left. Therefore, if the driver turns the direction of his body every time the wind direction changes, he will always receive the force of the wind.
2 can move.

Even if the wind stops and the wing 14 falls on the water, the wing 14 is made of synthetic fiber or the like, and the inside thereof is hollow, and further, the supporting rope is used. Since 18 is also made of synthetic resin, the blade 14
And the support rope 18 does not sink into the water. Then, if the next wind blows, it can receive the wind force,
You can immediately move on to the next move.

As described above, according to this embodiment, it is possible to easily enjoy without using waves. In this embodiment, a wing 14 capable of removing air, a supporting rope 18,
Since it is composed of the water ski plate 20 and the waist mounting portion 24, it is easy to carry. You can also enjoy full speed with wind power.

In this embodiment, the levitation body 12 is attached to the operator who wears the water ski 20 and the waist attachment portion 24.
However, the supporting rope 18 may be attached to, for example, a boat or a surf. Further, in the present embodiment, the first and second support bodies 32 and 34 are provided inside the blade 14, but it is also possible to provide no air inside the blade without providing any support.

Next, a second embodiment of the present invention will be described with reference to FIG. The floating body 12 of the second embodiment is a semicircular boat as shown in the figure. In the second embodiment, a pair of steering ropes 40, 40 are provided on the edge of the wing 14 to which the supporting rope 18 is attached, on the front side of the side end portion 16, and the steering rope 40 is It is attached to the levitation body 12. Like the supporting rope 18, the steering rope 40 is made of synthetic resin and has a diameter smaller than that of the supporting rope 18. In the present invention, for example, when the surface area of the wing is 7 m ² , the diameter of the steering rope is 1 mm, while the diameter of the supporting rope is 6 mm. In the present embodiment, the supporting rope 18 is fixed to the levitation body 12 so that the length of the supporting rope 18 from the levitation body 12 to the side end portion 16 is the same on the left and right. Further, the second embodiment is provided with a device (not shown) by which one of the supporting ropes 18 can be easily detached from the levitation body 12, and this device is, for example, a snap jackle used in a yacht. is there.

Next, a method of using the second embodiment will be described. Until the floating body 12 moves forward, it is the same as in the first embodiment. When the levitation body 12 is turned to the right, the supporting rope 18 is left as it is and the operator pulls the right-hand steering rope 40. This causes an imbalance such that the wing 14 twists to the right, and the levitation body 12 turns to the right. Then, when the hands are released from the pulling rope 40 for control, since the left and right lengths of the supporting rope 18 are equal, the wings 14 automatically return to the original balanced state, and the levitation body 12 is again moved. Move forward with wind power. On the contrary, when turning to the left, it can be done by the operator pulling the left control rope 40, and when the hand is released, the wing 14 automatically returns to the original position as when turning to the right. Return to a balanced state. Moreover, since the wing 14 falls forward by pulling the respective control ropes 40, 40 at the same time, the water surface moving body 10
