Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a windsurfing simulator for safely and easily training basic windsurfing operations on the ground.

[Conventional technology]

In order to be able to sail freely on the water with windsurfing, you must first stand on the board, raise the sail, hold the boom, point the board in the desired direction, and operate the sail so that it catches the wind. Must be.

Traditionally, training for these basic operations has been carried out suddenly at the sea or lake, which is not efficient as training is limited to moderately weak winds, and it is difficult to perform operations that stand up on the board and cause a sail. This requires a long period of training, but if you are heading from land to offshore, there is a danger that you will be far away from the shore without realizing it, and this is a big problem, especially for beginners. It has become.

Therefore, Japanese Patent Laid-Open No. 5 (1973) regarding a windsurfing training device
No. 9-69087 has been invented, but in this case, an aquarium is installed on land and a windsurfing device is installed in it, which increases the equipment cost for installing the aquarium and requires extensive training. There is.

[Problems to be Solved by the Invention] The present invention has been made to solve the above-mentioned problems of the conventional art. The object of the present invention is to provide an inexpensive windsurfing simulator that can be used safely and efficiently.

[Means to solve the problem]

As a means for solving the above-mentioned problems, the windsurfing simulator of the present invention has a movable frame at one end, which is provided with an operation console on which wheels are attached to the lower part and windsurfing units are attached to the upper part in the same direction. One end of the rotating frame is rotatably supported using the fixed part as a fulcrum, and the other end of the rotating frame is rotatably connected, and between the pulley attached to the operating table of the movable frame and the boot attached to the fixed part of the rotating frame. The movable frame and rotating frame are connected to each other by an endless cable via a pulley that rotates together at the connection part of the rotating frame, and the windsurfing on the operation console can be positioned at any position while facing the wind direction. can be moved to.

In addition, in order to move the windsurfing board in a well-balanced manner, it is best to attach each balance weight to the rotating frame connection part of the above-mentioned moving frame and the fixed part of the rotating frame, protruding in the opposite direction to the extension direction of each frame. desirable.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a plan view of a windsurfing simulator according to an embodiment of the present invention, FIG. 2 is a side sectional view of FIG. 1, and FIG. 3 is a side view showing the operating state of the windsurfing simulator of FIG. Figure 4 is a plan view showing the principle of the pulleys provided at the ends of each frame in Figure 1.
It is an explanatory view showing balance of each balance weight of a figure.

This windsurfing simulator shown in FIGS. 1 and 2 has a wheel 1 at the bottom, and a windsurfing 10 consisting of a sail 11, a boom 12, and a board 13 on the top, as shown in FIG. 3, in the same direction. A moving frame 3 has an attached operating table 2 at one end, and a rotating frame 6 is rotatably supported at the other end of the moving frame 3 with the rotating shaft 5 of the fixed part 4 as a fulcrum. 7, they are rotatably connected.

Next, the movable frame 3 and the rotary frame 6 are connected between the pulley 8A attached to the operating shaft 8 of the operating table 2 of the movable frame 3 and the pulley 5A attached to the rotary shaft 5 of the fixed part 4 of the rotary frame 6. They are connected and interlocked by an endless cable 9 made of a chain or rope through pulleys 7A and 7B, which rotate together on a pivot shaft 7, which is a connecting part of the two.

Note that the wheels 1 shown in FIGS. 2 and 3 are of a tire type that can move on a relatively flat ground 14, and the height of the operating table 2 from the ground 14 may be, for example, about 501. Desirably, each pulley 5A, 7A, 7B, 8A attached to the rotating shaft 5, the turning shaft 7, and the operating shaft 8, respectively.
A sprocket type pulley may be used.

Further, in this embodiment, a suitable weight W is provided by protruding toward the rotating shaft 7 side of the movable frame 3 and the rotating shaft 5 side of the rotating frame 6.
, a balance weight 3A of weight W and a balance weight 6B of appropriate weight W are provided respectively.As shown in FIG.
If the distance of A from the rotation axis 7 is b, the length of the rotating frame 6 is C, the distance of the balance weight 6A from the rotation axis 5 is d, and the weight on the operation console 2 side is W, then W-a −
Balance as Wl ・b, and (w+w,)c=
W-d is balanced, and the degree of freedom of movement of the simulator itself increases.

Furthermore, regarding the wind direction required during training in this simulator, two directions are set: wind 1iilX during running and wind direction Y during closed hold, and each wind is generated by a blower or the like (not shown). .

Next, the procedure for using the windsurfing simulator with the above configuration will be explained. In FIGS. 1 and 4, the moving point of the pulley 8A of the operation console 2 is
By fixing the pulley 5A attached to the rotating shaft 5 of the fixing part 4, the pulley 8A is formed.

In other words, the operation objects are A+, Az, All,
It can move while facing in a fixed direction like Aa.

On the other hand, by making the pulley 5A of the fixed part 4 free, the pulley 8A can move in a circle indicated by the actual fiR and freely move freely, so that the pulley 8A can move around the fixed part 4 as shown by the two-dot chain line in FIG. 360” allows windsurfing movement in any direction.

Here, the more equal the lengths of the movable frame 3 and the rotating frame 6, the more linear lateral movement of the console 2 becomes possible.

In addition, in FIG. 4, each pulley 5A, 7A.

To show that each direction of 7B and 8A is in a certain direction,
For convenience, the circumference is numbered from 1 to IO, and the rotational positions of pulleys 7A and 7B as the operation console 2 moves are indicated by B.
In addition, the position of the pulley 5A of the fixed part 4 is shown as C.

〔Effect of the invention〕

According to the windsurfing simulator of the present invention described above, even beginners can practice windsurfing on land by moving in a fixed straight line, in a circle, or in any direction with respect to the wind direction during running and the wind direction during closed hold. The effect is that training is carried out efficiently and with a high degree of safety, and the level of skill can be improved in a short period of time.

In particular, the simulator of the present invention does not use a water tank or the like,
Since it can be installed on relatively flat ground, equipment costs are low and windsurfing training can be done at a low cost.
