Abstract

An object of the present invention is to provide a bird and beast repelling device which aims at repelling a crow so that it does not nest on a tree and irradiates reflected light in various directions with different elevation angles. When hanging at the apex, such as a rectangular parallelepiped or a rectangular parallelepiped formed by combining mirror plates 11a, 11b, 11c, it is suspended at an appropriate apex of the polyhedron 1 having an asymmetric shape at the suspended center of gravity. A ring 12 is provided, and a rubber string 22 is attached to the suspension ring via a connecting part 21. By suspending the polyhedron on the desired tree, the reflected light from each specular plate will irradiate in different directions and positions with the shaking of the tree, and the birds and beasts (crows) do not approach the tree, nest You can stop making.

Description

  The present invention relates to a wildlife repelling device used to repel wildlife (especially crows).

  As a means of repelling birds and beasts (mainly crows), an instrument that uses reflection of sunlight is known. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-58415) discloses an instrument in which a strip with glass mirrors attached to each other is hung with a string, and Patent Document 2 (Registered Utility Model No. 3053306). (Patent Publication) discloses a device in which a horizontally long specular body and a rectangular specular body are vertically connected by a ring body and suspended by an elastic body.

JP 2002-58415 A. Registered utility model No. 3053306.

  The birds and beasts repelling device by sunlight reflection shown in Patent Documents 1 and 2 is hung above the garbage collection point, and the reflected light of the plate-like specular body irradiates crows (birds and beasts). To keep away from.

  However, the above-mentioned light reflection is in the range of the ground height, and it does not surprise the crows flying over the sky. In particular, in order to repel crows from trees in the urban area where crows nest, the plate-shaped specular body simply limits the irradiation range of reflected light and the reflected light is blocked by tree branches. So it is difficult to eliminate effectively so that crows do not nest.

  Therefore, the present invention proposes a bird and animal repelling device aimed at repelling crows on trees.

  The bird and animal repellent device according to claim 1 of the present invention is characterized in that a hanging ring is provided at an appropriate vertex of a polyhedron formed by combining mirror plates.

  Thus, if the polyhedron is a tree that you want to take measures to prevent the formation of crow's nest or a tree close to it, if it is hung in a position that is susceptible to sunlight, the tree will be shaken by the wind, so the polyhedron will rotate with vertical movement Movement is performed, and the reflected light is irradiated in different elevation angles and rotation angle directions.

  Moreover, the bird and animal repellent device according to claim 2 of the present invention is further provided with a hanging ring at an appropriate apex of a polyhedron formed by combining a mirror plate, and a rubber string is attached via a return connecting portion. However, by interposing a rubber string between the tree and the polyhedron, the up and down movement of the polyhedron is expanded, the sudden movement of the tree is absorbed, and the twisted string (rubber string) is excessively twisted by returning. To prevent.

Further, in the bird and beast repelling device according to claim 3 of the present invention, the polyhedron has an asymmetrical shape (for example, a rectangular parallelepiped or a rhomboid) at the hanging center of gravity line of the hanging ring. The reflection light of each mirror surface of the polyhedron is different in elevation angle, and the reflected light irradiation range is widened.

  The configuration of the present invention is as described above. By hanging the polyhedron on a desired tree, the reflected light from each mirror plate of the polyhedron irradiates in different directions and positions with the shaking of the tree. (Crows) could not get close to the tree and could be eliminated so as not to nest.

1 is an overall perspective view of an embodiment (first example) of the present invention. Explanatory drawing of the same use state. Explanatory drawing of the principal part (rubber string). The whole perspective view of the second embodiment. The whole perspective view of the said 3rd Example. The whole perspective view of the fourth embodiment.

  Next, an embodiment of the present invention will be described. FIG. 1 to FIG. 3 show a first embodiment. The bird and animal repellent device according to the first embodiment includes a polyhedron 1 and a suspension member 2.

  In the polyhedron 1, the surface of each surface is formed by mirror plates 11a, 11b, 11c... And a hanging ring 12 is provided at an appropriate apex. The mirror surface plates 11a, 11b, 11c,... May be a resin mirror plate or a mirror polished stainless steel plate, and are attached to the surface of an appropriate frame to form the polyhedron 1, and the hanging ring 12 is also attached to the frame. Link.

  The suspension member 2 includes a return body 21 that is detachable from the suspension ring 12 and a rubber cord 22 that is further tied to the return body 21. In particular, the rubber string 22 is formed by bundling a plurality of round rubbers or narrow flat rubbers and forming knots 23 at appropriate intervals, and the bundled one is broken as compared with the case where a single rubber string is employed. However, since the load of the polyhedron 1 can be supported by another rubber cord, the durability is excellent.

  The bird and animal repellent device hangs the polyhedron 1 by tying the rubber string 22 to an appropriate branch of a desired tree A so that crows do not nest. The hanging position is a place where sunlight is as easy as possible.

  Thus, the suspended polyhedron 1 swings up and down and left and right as the tree is swung by the wind, and the polyhedron 1 itself also receives the wind and rotates. When this polyhedron 1 is exposed to sunlight, the mirror plates 11a, 11b, 11c,. The reflected light is irradiated at different elevation angles depending on the specular plates 11a, 11b, 11c,... And the reflected light is applied to a wide area of the tree A by the vertical movement and rotation of the polyhedron 1.

  Accordingly, the crow does not come close to the tree A, and naturally no nesting is performed.

  The polyhedron 1 is not limited to the first embodiment, but is a rhombohedral polyhedron 1A shown in FIG. 4 (second embodiment), and a triangular pyramid and a quadrangular pyramid shown in FIG. 5 (third embodiment). An appropriate polyhedron can be employed, such as the polyhedron 1B and the polyhedron 1C composed of an octahedron shown in FIG. 6 (fourth embodiment).
