However, it has been pointed out in the above-mentioned patent document that the method using the scarecrow and the air cannon is neutralized due to the high learning ability of the birds, and it is pointed out in the above-mentioned patent document. It is unsuitable for use in residential areas.
In recent years, home gardens using garden flower beds, apartment veranda planters and the like have been widely used in residential areas, and such gardens are often damaged by birds. For this reason, various devices and equipment as described above have been devised, but further improvement techniques are required.

The inventor has reconsidered the above-described conventional technology, and has studied the device for preventing the birds from coming close efficiently, and has come up with the present invention. That is, the present invention provides a bird repelling device having a structure that generates a sound that can be used even in a residential area while using a magnet, a reflector, and the like.

Specifically, the present invention is provided with rotatable rotor blades on both sides of the main body simulating the shape of a bird, and (a) a magnet and (b) a reflector are attached to the rotor blade. The purpose is to play. Furthermore, in order to surprise birds and make them inaccessible, the greatest feature is that (c) a sound generating portion is provided in the main body portion or the rotor blade portion. The present invention relates to a bird repelling device comprising at least one of the parts (a) to (c).

According to the bird repelling device according to the present invention, the shape of the main body imitates the shape of the bird itself in addition to the magnet, the reflector and the sound-damping effect, so for example when this is used in a home garden Because the rotor blades imitating the blades are rotating with awkward sounds, birds who have sensed an unusual situation are expected to detect danger and not come close. Also, by letting the bird know that it is dangerous to turn the main body upside down and look like a dead bird, it is said that it will not bring birds to the vicinity where the bird repelling device according to the present invention is installed The effect is expected.

In the following, an embodiment of the present invention will be described using the example shown in FIGS.
FIG. 1 is a side view of a bird repelling device according to the present invention, and FIG. . The case (3) contains a small ball (8) for generating sound.

The bird repelling device of the present invention shown in FIG. 1 is provided with a rotatable rotor blade (2) on both sides of a main body (1) simulating a bird shape, and a magnet (4) on the rotor blade (2). A reflector (5) is attached. Furthermore, in order to surprise birds and make them inaccessible, a case (3) is provided that encloses a small ball (8) serving as a sound generation site at the center of the rotor blade (2).

In the present invention, the greatest feature is to provide one or more of the following parts on the rotor blade.
(A) Magnet (b) Reflector (c) Sound generation site

Next, each part will be described in detail.
The main body (1) imitating the shape of a bird according to the present invention may be the same size and color as a bird to be repelled. For example, in the case of a crow, the main body (1) is colored about black with a length of about 50 cm. In the case of, it is appropriate to have a blue-gray color of about 30 cm, and in the case of buds, it is appropriate to have a tea-based color of about 25 cm. The material is not particularly limited, and may be made of light wood such as balsa material, plastic material such as polycarbonate, polystyrene and polyethylene, and light metals such as aluminum and steel. The material is not particularly limited as long as it has a hole penetrating the main body portion (1) and the rotor blade (2) is attached through the hole, and has a strength that can withstand wind and rain.

Next, the rotor blades (2) attached to both sides of the main body (1) are not particularly limited as long as the rotor blades are rotated in response to the wind, and may have any shape including bamboo dragonflies, windmills, propellers, and hemispherical cups. However, it may be anything that rotates in response to the wind. The material may be a lightweight material that can withstand wind and rain as in the case of the main body, and examples thereof include plastic materials such as wood, bamboo, light metal, polycarbonate, polystyrene, and polyethylene. If the size of the rotor blade (2) is too small compared to the main body (1), the effect of repelling birds will be insufficient, and if too large, the device itself may be damaged by the force of rotation, which is not preferable. For example, it is preferable that the length is the same as the length of the main body (1). Specifically, in the case where a main body simulating the above-mentioned crow is formed, when a bamboo dragonfly type rotary wing is adopted, the diameter of the wing is about 50 cm, the width is 5 cm, and the thickness is about 1 cm.

The main body (1) and the rotor blade (2) pass through the shaft (7) through a hole extending from the side surface of the main body (1) through the main body (1) to the opposite side surface, and the shaft (7). What is necessary is just to attach a rotary blade (2) to the both ends. As for the attachment method, it is only necessary to fix the rotating blade (2) and the shaft (7) together with an adhesive or the like in addition to screws. The material of the shaft (7) may be wood, bamboo, iron, or a plastic material, but a plastic material is preferable because of ease of processing and molding.

The magnet (4) used in the present invention may be a generally available permanent magnet, and the shape thereof may be any of a tablet shape, a plate shape, a columnar shape, and a sheet shape. The size of the magnet used should not affect the rotation of the rotor blade (2). For example, in the case of a crow, a tablet or sheet magnet having a diameter of 2 cm and a thickness of about 2 mm is used as the rotor blade (2). Can be pasted on both ends, or a rod-like magnet having a length of 2 cm and a cross-sectional area of about 1 cm2 can be inserted into the groove provided in the rotor blade (2) or adhered with an adhesive, and it can be simply sheet-like The magnet may be cut into an appropriate size and attached with an adhesive or a double-sided tape so as not to easily fall off.

At this time, it is necessary to attract the magnet attached to the rotor blade on the opposite side of the main body, and to have a size and magnetic strength that do not hinder the rotation of the rotor blade, but it is particularly necessary to consider the orientation of the poles Absent.

The reflecting plate (5) can be used without particular limitation as long as it has an effect of receiving light from the sun or the like and reflecting or irregularly reflecting the light. Preferably, it is convenient if the rotor blade (2) itself is formed of a material that becomes a reflector. Examples of materials used include plastic materials such as polycarbonate, polystyrene, and polyethylene in which fluorescent dyes, aluminum foils, and the like are dispersed or coated with these.

The sound generating part is a part that emits a sound to surprise the bird. A case (3) having a hollow inside is provided at the tip of the rotor blade (2) or the joint with the shaft (7). 3) By inserting a bell or small ball (8) in the case, when the rotor blade (2) rotates in response to the wind, the bell or small ball (8) rolls in the case (3) and becomes irregular. Sound is generated. In order to produce more effective sound, it is possible to provide a slit that does not drop the bells or small balls (8) contained in the case (3). The material of the case (3) may also be formed using the same material as that of the rotor blade (2), and the rotor blade (2) has a structure that can enclose the same bell or small ball as one of the internal structures. It may be provided.

Further, the inside of the main body (2) is hollowed out, and a case (3) including the above-mentioned small balls (8) is provided in the inner part of the main body (1) of the shaft (7) penetrating the main body. It is good also as a shape which makes the slit and hole which make a sound in (1). The bell used here may be a commercially available one, and the small ball may be made of glass such as marbles, iron such as pachinko balls, or wooden or plastic. Even if it is any of a bell and a small ball, it is sufficient that about 1 to 5 pieces are included in the case (3) so as to have a gap that can sufficiently rotate in the case (3). Specifically, it may be appropriately selected from about 0.3 to 2 cm.

Any of these three types of sites can be used alone or in combination, and an effect obtained from a plurality of sites can be expected when used in combination. Furthermore, since the shape of the bird repelling device according to the present invention simulates a bird, it can be used in a kitchen garden or a planter without a sense of incongruity.

The bird repelling device having the above configuration can be used in any place by providing a rod-like support (6) or a fixing clamp on the lower surface of the main body by a known method. For example, when it is used for a kitchen garden or a planter, it may be attached to a rod-shaped support (6) and pierced and fixed to the soil surface. Moreover, when using it on the veranda etc. of an apartment, a clamp can be attached and it can fix to the handrail etc. of a veranda. If it is a garbage collection point, it is possible to enhance the effect by attaching a plurality of bird repelling devices according to the present invention around the device.
