Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decoy of a crow which repels a crow by inducing damage association and a method of manufacturing a control device for preventing habituation.

[0002]

2. Description of the Related Art A conventional decoy of a crow is intended to repel sparrows and doves by suspending it in a normal flight state. There were no crow decoys and their controls to repel crows.

[0003]

The imitation decoy of the conventional crow has a problem that a constant crow repulsive effect cannot be expected because the crow does not have an effect of inducing damage association to the crow. The present invention expresses and emphasizes fear and intimidation by a combination of a crow's artificial decoy that represents the aggression state and the sound of fluttering when moving, screaming, screaming, etc. It is an object of the present invention to provide a method of manufacturing a control device for preventing habituation and a decoy of a crow.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, an inverted suspension is used as a mimicry of the expression of aggression.
By connecting natural and imitation wind-faces, an illusion that resembles the appearance of damage by a natural crow is induced at a distance, and the crow is repelled by preventing habituation.

The biggest problem with the crow repelling device is how to get used to it, and the crow, which has the highest alertness and associative power of the crows, accidentally exposes the aggression mode and approaches. Repeatedly appealing to the visual and auditory sense by mimicking the danger signal, in order to meet the same dangerous eyes.

Further, as a means for preventing habituation, instead of a fixed one-sided posture, a movement that constantly changes and operates is taken in response to it, and flapping of both wings and rocking of the posture are intermittently activated.

Further, human power, wind force, and
Electric power can be used, but with fixed time fixed to operate in the early morning, daytime, evening, etc., automatic control of time, switch and optical switch (photo switch) that operates with brightness etc. It is also possible to control.

[0009] In addition to the above operation, the re-voice of the recording of screaming and screaming at the time of harm, which is particularly effective for the occurrence of fear and intimidation, is more effective, and is also accustomed to the action of creating a serious danger signal or danger zone. According to the degree of the stage, it will be combined in stages.

In order to protect and maintain the area of the danger zone where the crow is vigilant, imitation decoys of the crow are hung at high intervals upside down so as to be conspicuous as much as possible, and in order to constantly raise the awareness of the danger level of the area, The crow's artificial decoy was hung upside down with a thread of about 1 m on the tip of the prepared bamboo pole of 3 to 4 m and swung around, and threatened by threatening the crow approaching at times and making the area of the danger zone against the crow conscious And constantly protect the area.

[0011]

[Function] By suppressing the habit of imitation decoy of the crow configured as described above, even if a human may exterminate a part of the crow, as long as another crow exists,
A substitute crow invades and the damage is repeated, but humans arbitrarily specify a certain area by fear and threatening tactics of the present invention, and newly

It is a control function that controls the exclusion and repulsion by declaring [dangerous, keep close, go out].

Also, the upper and lower intermittently bonded portions 9 shown in FIG.
The wings bend downward and extend downward, but the bent surface acts as a hinge and flutters and swings in response to movement and wind.

Further, an electric waterproof small motor 23 attached to the arm 16 for making a positive movement in the imitation decoy of the crow is rotated at a low speed by a gear, and is connected to the main shaft of the rotating arm and the rotating disk (tan table). The set fulcrums 25 and 22 are eccentric to the main shaft, and produce a vertical motion when rotated sideways, and a swinging orbital motion when rotated downward.

[0014]

EXAMPLE An example will be described with reference to some drawings. In FIG. 1, thin films of plastic or rubber having weather resistance are combined and bonded or thermocompressed to form a crow, and blown with air. The crow is shaped like a balloon in the shape of a hollow crow, and a suspension 8 is attached to the tip of the tail portion 7 of the artificial bait 1 of the crow, and the air injection valve 6 is provided near the tail portion or under both wings (3a, 3b). It is attached to either the right or left ventral part, and both wings naturally hang down along the body 2 and extend, and the natural and imitation wind blades are connected to the tubular holes of the attachment part 4 of the wind blades of both wings. 5 are connected and juxtaposed in a row to be adhesively fixed.

In the embodiment shown in FIG. 2, both wings (3a,
3b) the upper and lower inner surfaces of the root of the base of the joint, which are discontinuous, are bent downward while allowing air to pass therethrough, so that both wings flutter and swing in accordance with movement and wind.

Further, in the embodiment shown in FIG. 2, the wind-blade mounting portion 4 is integrated into both the blades (3a, 3b) and the wind-blading blade 5 without being separated, and the integrally-molded blade 10 and one of the blades are formed. A natural wind blade 5 is embedded and adhered to the place 11 left out of the place.

In the embodiment shown in FIG. 3, first, a branch line 14 is attached to a pole 13 such as a plastic or a conset pipe, which is bound to a pillar pile 12 driven into the ground, and is fixed with a retaining pile 15, and a arm bar 16 is attached to this pole. Attach it and attach the pulley 17 near its tip, close to the base of the pole, and attach the metal or plastic storage box 18 in which a small drive motor 19, mini stereo, mini amp,
Batteries etc. are stored, and a string or thin wire 27 for hanging a dummy decoy of a crow is tied to a fulcrum 22 at the side end of a rotary disk (tan table) 21 connected to a motor spindle, and it is attached to a pole. A balance weight 28 and a crow's artificial decoy are attached to the tip of the extension and the descent through the pulley to create a fluttering swing of vertical movement.

Further, in the embodiment shown in FIG. 3, the storage box 1
A mini-stereo / mini-amplifier stored in 8 that records the screaming and screaming when the crow was harmed by the association of the present invention with the damage association induction. Play the tape and sing through the speaker 29 at the top of Paul. In this case, in order to set and operate a certain time zone such as early morning, daytime, and evening, the time switch and the optical switch (photo switch) that operates with brightness may be activated, and automatic voice output is performed for continuous vocalization. A reverse mechanism is preferred. Furthermore, in addition to the above, by combining the mechanism, a set of speakers, mini stereo, amplifier, etc., can be used as a portable device in a form similar to a handheld microphone, and used as small as possible in a patrol destroyer.

In the embodiment shown in FIG. 4, the pole 13
The waterproof small motor 23 attached downward near the tip of the arm 16 to be connected to is fixed by a stopper b20, and the balancer 26 is attached to one side end of the rod-shaped turning arm 24, and the other side end thereof is also attached. The artificial decoy of the crow suspended from the fulcrum 25 of the above makes a circular motion of swinging by the rotation of the drive motor. In this case, if the mounting method of the drive motor of the arm 16 is changed and the arm is turned sideways, the imitation decoy of the crow will flutter and swing up and down.

As an example of application of the embodiment incidental to the present invention, when an imitation decoy of a crow is made to resemble a hawk and swung,
It should be possible to help sparrows, pigeons and other harmful birds. In addition, as an incidental matter, it is convenient to use the wind blades used for the artificial decoy of crows by dyeing the wind blades of chickens, which are relatively easily available, with a weather-resistant paint or by spraying the paint with a black paint.

[0021]

[Effects of the Invention] Eclectic processing of artificial and natural combinations hides unnaturalness and maintains the threat of crows, while combining measures that are suitable for the degree of familiarity to achieve constant habituation. Pressing down to make the effect permanent.

Compared to the case of using a natural crow's body, it is difficult to replenish it, and it is possible to overcome the weathering resistance of corrosion and to use it for a certain period of year.

This crow decoy is simply inflated with air and suspended when necessary, so that it is easy to operate and lightweight and compact, and thus easy to handle.

In addition, the mechanism is composed of multi-stage fear and intimidating repetitive control, and it also corresponds to the multi-stage condition of the crow, with the imitation decoy of the crow being a permanent danger zone, Crows can be shunned and stay away, thus helping to control damage.
