Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) This invention relates to a car that runs on wind power.

(Prior Art) This type of conventional vehicle is called a land yacht, and like a yacht, it runs by changing the direction of its sails depending on the direction of the wind.

(Problems to be Solved by the Invention) The aforementioned land yacht has the advantage of being able to travel freely by changing the direction of its sails, but it has the problem that it is difficult to operate for children to play with.

Therefore, the purpose of the present invention is to change the direction of the vehicle body depending on the direction of the wind so that the vehicle can travel while being sufficiently exposed to the wind at all times.

[Structure of the invention] (Means for solving the problems) The car that runs on wind power according to the invention has rotatable wheels 3 and 3' mounted on both sides of the car body 1, respectively.
A rotatable direction-changing wheel 8 is attached to the other side of the vehicle body 1 on a vertical shaft 6 so that the running direction can be changed with respect to the vehicle body 1, and a rudder 11 whose direction changes depending on the wind is attached to the vertical shaft 6. The wheels 3 are mounted on both sides of the vehicle body 1 so that they can rotate in the opposite direction in conjunction with each other.
A sail 16 is fixed to the upper surface of the side where 3' is provided.

(Function) In the present invention, when the wind blows from a direction perpendicular to the sail 16, the vehicle body 1 runs parallel to the rudder 11 and the direction changing wheels 8, but when the direction of the wind changes, the rudder 11 moves the wind. Change direction to receive and blow. This rotation of the rudder 11 causes the vertical axis 6 to
are interlocked to rotate the direction changing wheel 8 in the opposite direction. With this rotation of the direction changing wheels 8, the traveling direction of the vehicle body 1 is changed to the traveling direction of the direction changing wheels 8, so that the sails 16 can receive sufficient wind. As the running direction of this vehicle body 1 changes, the rudder 1
1 and the directions of the direction changing wheels 8 are also parallel to the traveling direction of the vehicle body 1.

(Embodiment) An embodiment of the present invention will be described in detail with reference to the drawings.Brackets 2, 2' are fixed to one side of a rectangular vehicle body 1, and wheels 3, 3' are rotated by these brackets 2, 2'. I freely support it. Further, on the other side of the vehicle body 1, two fixing plates 4, 4' are provided upwardly projecting outwardly to support the support plate 5 horizontally. A vertical shaft 6 is rotatably passed through the support plate 5, a U-shaped wheel support member 7 is fixed to the lower end of the vertical shaft 6, and a direction changing wheel 8 is rotatably mounted on the wheel support member 7. ing.

In addition, a V-pulley 9 is attached to the vertical shaft 6 on the upper side of the support plate 5.
A rudder support tube is fixed to the vehicle body 1, and a rudder 11, which rotatably passes through a pulley support plate 10 above the pulley support plate 10, and whose direction changes in response to the wind, is fixed to the upper side of the pulley support plate 10. 12 are fitted together so as to be rotatable and not to come off. And the rudder support tube 1
A V-pulley 13 is fixed to the lower end of the V-pulley 2 so as to be parallel to the V-pulley 9. Moreover, the pulley support plate 10
On the opposite side of the vehicle body 1, there are intermediate pulleys 14 and 1 on both sides.
4' is mounted rotatably in the vertical direction and hooked on the V pulley 9 via the V pulleys 14 and 14', and the V
A pulley 13 and a V-pulley 9 are formed to rotate in opposite directions.

Further, a sail 16 is fixed to the upper surface of the vehicle body 1 on the side of the wheels 3 and 3' to allow the vehicle body 1 to travel while sufficiently receiving wind. In addition, 17 and 17' in the figure are stoppers for sail 1.
6 is designed to prevent it from colliding with objects and being damaged.

The present embodiment is constructed as described above, and the sail 16 receives the wind that normally blows in the direction of arrow A at right angles to cause the vehicle body 1 to travel in the direction of arrow A, as shown in FIG. 3A. In this state, if the direction of the wind changes to the direction of arrow B as shown in B, the sail 16 will only be able to receive the force component of the broken line arrow B'. At this time, the rudder 11 receives the wind and rotates clockwise as shown in C, causing the direction support tube 12 to rotate clockwise. Along with this rotation, the V pulley 13 rotates clockwise, and the V belt 15 causes the intermediate pulley 14,
The V-pulley 9 is rotated counterclockwise via 14'. The rotation of the V pulley 9 in the counterclockwise direction causes the direction changing wheel 8 to rotate in the counterclockwise direction so as to be inclined with respect to the traveling direction of the vehicle body 1. The vehicle body 1 changes direction in the direction of arrow C so that the vehicle body 1 faces in the running direction of the direction changing wheels 8. This allows the sail 16 to receive sufficient wind, as well as the rudder 11 and the direction changing wheels 8.
becomes parallel to the direction of arrow B, and the vehicle body 1 travels in the direction of arrow B.

Also, as shown in Figure 4 B, the direction of the wind is indicated by the arrow.
When the direction is changed to B', the rudder 11 rotates counterclockwise, contrary to FIG. 3 (see C), and the direction changing wheel 8 rotates clockwise. As a result, car body 1
Change direction so that it is parallel to arrow B′ as shown in D.

It has a simple structure and can be manufactured by children.

[Effect of idea]

In the present invention, the sail 16 is fixed to the car body 1 and the traveling direction of the car body 1 is automatically changed to be parallel to the wind direction, so that the sail 16 can receive sufficient wind.

As a result, the vehicle body 1 can be driven in accordance with the direction of the wind.
