Since the plane was shaped like a plane with a horizontal tail on the surface, when the wind blows, it seems that the plane is flying around while sometimes making swirl flight and horizontal rotation flight, so you will not get tired of watching and value as an exterior Will increase.

  In the invention according to claim 3, in the anemometer / bird protection device according to claim 1 or 2, since the weight is provided on the lower side of the fuselage, even if the fuselage is turned upside down by the wind, By the action of the weight, it can return to the original posture.

It is a figure which shows the anemometer combined use bird guard which concerns on one Example of this invention. FIG. 2 is a plan view of the anemometer / birdbird device of FIG. 1. It is a figure for demonstrating how to make a propeller. It is a figure which shows an example of the conventional bird guard. It is a figure which shows an example of the conventional anemometer.

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

  FIG. 1 is a view showing an anemometer / bird guard according to an embodiment of the present invention, and FIG. 2 is a plan view thereof. 1 and 2, 1 is a fuselage, 2 is a main wing, 3 is a horizontal tail, 4 is a vertical tail, 5, 6 is an opening, 7 is a propeller, 8 is a weight, and 9 to 11 are support shafts.

  In this embodiment, a used plastic bottle for beverage is reused to form a zero battle. The body 1 cuts a part of the side surface of the empty plastic bottle with a knife or the like to open the openings 5 and 6 to form windows, and puts a brush through the openings 5 and 6 to apply the paint to the inner surface of the plastic bottle. The body 1 is colored. Further, the main wing 2 is provided on both side surfaces of the center part of the fuselage 1 so as to project on both the left and right sides, the horizontal tail 3 is provided on both sides of the rear end, and the vertical tail 4 is provided on the upper surface of the rear end. Yes. The attachment to the trunk | drum 1 can be performed using appropriate means, such as screwing and adhesion | attachment.

  Further, a propeller 7 is provided at the front end of the body 1. This propeller 7 is made using the bottom part of another plastic bottle. To make it, first cut a few centimeters of the body from the bottom of the plastic bottle into a cup with scissors. Then, as shown in FIG. 3, a plurality of cuts C and D are made from the cut edge portion A toward the bottom B. At this time, the length of one cut C is made longer than the length of the other cut D. Further, a cut E is made in the lateral direction, leaving a portion F to be used as a propeller blade, and the portion F to be used as a propeller blade is folded outward along a line G connecting the lower ends of both cuts C and D.

  The propeller 7 thus created is arranged at the front end portion of the body 1, and the horizontal axis of the first support shaft 9 is passed through both of them. Further, a weight 8 is attached to the lower side of the center portion of the body 1. The weight 8 simulates a bomb and can be made by processing a piece of wood, for example. The fuselage 1 and the propeller 7 are individually rotatable about the horizontal axis of the first support shaft 9, and the fuselage 1 is blown by the wind to rotate and may be turned upside down. Even so, the weight 8 returns to the original horizontal position.

  The behavior of the body 1 in response to such a wind can be adjusted by changing the weight of the weight 8. That is, when the weight 8 is made heavy, the body 1 is difficult to rotate even if a little wind blows, and the posture is stabilized. On the other hand, when the weight 8 is lightened, the body 1 is easy to rotate and the movement becomes light. From such a point of view, the weight 8 should be selected so as to make the desired movement.

  The effect of the weight 8 also changes depending on the attachment position of the weight 8. That is, even if the weight 8 has the same weight, the rotation of the body 1 is suppressed as the position of the weight 8 is separated from the horizontal axis of the first support shaft 9 (as it is attached to the outside of the body 1 away from the body 1). Can do. On the other hand, the closer the weight 8 is to the horizontal axis of the first support shaft 9, for example, when it is attached to the inside of the body 1, the body 1 becomes easier to rotate and the movement becomes lighter.

  The first spindle 9 is bent at a right angle from the horizontal axis and the vertical axis extends downward. The vertical axis is inserted into the cylindrical portion 13 of the second spindle 10 and is integrated with the vertical axis. The flange 12 provided on the upper end of the cylindrical portion 13 is rotatably held in contact with the upper end edge of the cylindrical portion 13. The second spindle 10 has a cylindrical portion 13 at the upper end, extends downward from the lower end of the cylindrical portion 13, then bends at a right angle and extends in a horizontal direction, and further bends at a right angle and downwards. It extends and has a crank shape. And the lower end part is inserted in the cylindrical part 15 provided in the upper end of the 3rd spindle 11, and the collar 14 integrally provided in the lower end part contact | abuts the upper end edge of the cylindrical part 15 It is held so that it can rotate freely.

Since the body 1 is supported by the first support shaft 9, the second support shaft 10, and the third support shaft 11, the cylindrical portion of the first support shaft 9 and the second support shaft 10 is used. 13 and between the lower end portion of the second support shaft 10 and the tubular portion 15 of the third support shaft 11 can be freely rotated in the horizontal direction. The support shaft 9 can be freely rotated around the horizontal axis. Therefore, the horizontal axis of the first support shaft 9 moves in various positions in the horizontal direction according to the wind blowing condition, and the body 1 supported by the horizontal axis can move freely in the horizontal direction. In addition, it can freely rotate around the horizontal axis of the first support shaft 9 and can move like a turning flight or a horizontal rotation flight. Even if the body 1 rotates around the horizontal axis of the first support shaft 9 and is turned upside down, the weight 8 is provided on the lower side, so that it can return to the original horizontal position. .

  As described above, the fuselage 1 exhibits a complicated movement in accordance with the blowing condition of the wind, and the main wing 2 overlaps with the wing of the bird, which is combined with the resemblance to the bird, thereby increasing the threatening effect on the bird. By looking at the movement of the body 1, not only the wind direction but also a complicated change in the wind, such as how the wind is wound, can be understood. In addition, you will not get tired of seeing the movements complicated, and the value as an exterior will increase.

  In the above-described embodiment, the fuselage 1 attached to the horizontal axis of the first support shaft 9 has an airplane shape, but is not limited thereto, and other shapes such as a helicopter or a bird may be used. In that case, when making the shape of a helicopter, the left and right skids (legs) can be made thick. Moreover, when it makes it the shape of a bird, if it makes the shape resembling a raptor like a eagle and a hawk, the effect of bird removal can be heightened. At that time, if the shape of the prey is grabbed by the nail of the leg, the prey can be weighted.

  Moreover, in the said Example, it produced using the used PET bottle. If such a used PET bottle is used, the resource is effectively used. However, the material is not necessarily limited thereto, and an appropriate material such as molding from a plastic raw material can be used.
