Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for chasing birds when they approach the device to prevent harm to the birds.

[Prior Art 1] At present, so-called pigeon damage, in which pigeons fly onto balconies and cause damage by dropping on balconies, etc., has become a problem in residential buildings, general residences, and other buildings. Furthermore, in fields and orchards, crows such as sparrows, crows, and pigeons cause damage by pecking at seeds that have been sown, or by pecking at crops.

For this reason, various methods have been used to disperse birds, such as:
As shown in Japanese Utility Model Application Publication No. 62-104679, a bird chaser has been proposed in which an eyeball pattern is drawn on a balloon-shaped bag made of plastic film. When the wind blows, these bird chasers move, and their large eyeballs move to frighten the birds and try to scare them away.

[Problem to be solved by the invention 1 However, in the above conventional example, the bird chaser with the eyeball pattern does not move unless the wind blows, and therefore the effect of driving away the crows is not very good. . Furthermore, when the wind blows, there are no birds (but there was a problem in that the bird chasers formed from balloon-shaped bags made flapping noises and were noisy).

The present invention was invented in view of the problems of the above-mentioned conventional examples, and its purpose is to ensure that the eyeball moves only when a crow flies, regardless of whether the wind is blowing or not. To provide a bird chasing device which can disperse crows, does not move without crows even when the wind is blowing, and does not make the sound of flapping by the wind as in conventional devices.

In the embodiments shown in Figures, #S9, etc., the size of the eyeball body 4 is always the same, and the eyeball body 4 of the same size is always exposed regardless of the presence or absence of the crow 1. However, the eyeball body 4 is formed of an elastic bag-like material, and when the crow 1 is not present, it contracts and becomes compact, and when the bird detection means 2 detects the island 1, it expands or expands. It may be designed to repeat contraction.

That is, an air pump 24 is installed inside the main body case 13, a balloon-like eyeball 4 is connected to the end of an air passage 25 connected to the F-pump 24, and there are no birds in the detection area of the bird detection means 2. At times, the air pump 24 does not operate, so the eyeball body 4 is in a contracted state as shown in FIG. As shown, the eyeball body 4 is designed to swell.

Effects of the Invention 1 The present invention is composed of a bird detection means for detecting the presence of a bird as described above, and an eyeball body having an eyeball display section that moves when detected by the bird detection means. Unlike conventional methods, regardless of whether the wind is blowing or not, when a crow flies in, the bird detection means will always detect the crow and the eyeball will surely move to disperse the crow, and Even if the wind is blowing, if the crow is not present, the eyeball will not move, and as a result, the sound of the eyeball flapping in the wind will not be heard as in the past.

In addition, by making the eyeball body having the eyeball display part spherical and providing a plurality of eyeball display parts around this spherical eyeball body,
No matter where the crow is in the front, rear, left, right, or upper and lower positions relative to the eyeball, the crow can see the eyeball display, and by moving the eyeball, the crow can be reliably dispersed.

Furthermore, by providing the eyeball display section with a light emitting device, the light emitting device is turned on to illuminate the eyeball display section, thereby making it possible to effectively disperse birds.

Furthermore, by providing a lens on the eyeball display section, it is possible to converge the light or, conversely, to diffuse it, thereby scattering the crows.

By making it possible to select different movements of the eyeball, it is possible to scatter the birds by selecting various movements of the eyeball.

In addition, by making the rotatable arm that supports the eyeball body telescopic, the arm can be extended or retracted depending on the installation location.
By shrinking it, you can choose the most effective eyeball level depending on the installation location to intimidate the crows.

In addition, by imparting spring properties to the rotatable arm, when the arm moves with a drive source, the movement of the spring part of the arm during rotation is added to the movement of the drive source, resulting in complex movement. This further improves the effect of dispersing.

In addition, by causing the eyeball body to repeatedly expand or expand and contract using the bird detection means, the eyeball body expands when a crow flies and can scare the crow and scare it away.

Not only the eyeball body but also the arm expands, making it even more effective to scare the crows away.

Further, by providing a sound generator that makes a sound when the eyeball body contracts or the eyeball body and arm contract, the crows can be effectively startled and dispersed by the sound linked to the movement of the eyeball body.

In addition, as the inflated arm swings irregularly, the inflated arm and the inflated eyeball make complex movements and sway as if they were alive, making it possible to frighten the crows and drive them away.

In addition, by placing the eyeball that expands and contracts in parallel with the eyeball that always remains the same size, the synergistic effect of the two can startle the crows and drive them away.

In addition, by providing a safety device that stops the eyeball's movement when it hits a resistive object such as a human body, if a person is hit or pinched, the safety device will stop the eyeball's movement and cause an accident. It is safe and can prevent this.

Furthermore, by detecting the sound of flapping bird wings as a bird detection means, it is possible to reliably detect the arrival of a crow.

Furthermore, by arranging the bird detection means at a different position from the device to which the eyeball is attached, it is possible to place the bird detection means at the position where birds fly the most, making it possible to effectively catch ravens. .

Furthermore, by providing a sound wave generating means that emits sound waves upon detection by the bird detection means, the sound waves are emitted in addition to the movement of the eyeballs, and the synergistic effect of these can reliably disperse the crows.

Furthermore, by providing a solar cell as a power source, it can be easily installed outdoors, such as in fields, orchards, or on balconies.

Furthermore, by providing a flash device that emits a flash of light when detected by the bird detection means, the flash can be emitted in addition to the movement of the eyeballs, and the synergistic effect of these can reliably disperse crows.
