Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The object of the present invention is to fly to fields and orchards,
Alternatively, the present invention relates to a technology for threatening small animals such as wild birds and rats that inhabit the surroundings and harm the crops and seeds after sowing, and in particular, a novel structure utilizing the property that these small animals repel raptors. It is intended to provide a bird-watching tool consisting of

[0002]

2. Description of the Related Art Starlings that inhabit many parks, shrines, and villages in urban areas and nest under eaves and rain gutters of buildings, and starlings that come to Hokkaido and the Tohoku region as summer birds have electric wires, antennas, and verandas. It only stops at the railing, etc. and disperses feces around it, pollutes the roofs and windows of houses, outdoor facilities, etc., and also creates nests and disperses dead grass and straw etc. In particular, horticultural farmers who cultivate fruits that are easily targeted by wild birds, such as cherry blossoms, grapes, and persimmons, apply a series of manure and pruning in winter to control ash sickness, etc., and take measures to prevent fruit cracking during the rainy season. After being chased by the growing work that takes a long time, at the end of the harvest season, wild birds such as starlings flying in a group from nowhere flock to the fruit field and eaten the fruits just before the harvest, Takubaku Regardless of the scars, the fruits are completely lost in commercial value and are severely affected economically, so the problem in these farms is not the ratio of the ordinary citizens, but the cherry growing area. In Japan and other countries, the starling that causes such damage is called a cherry tree and it is abhorrent.

[0003] For this reason, as a technique for preventing such damage by small animals including wild birds, for example, a bat or a crow hung on a hanging string is not attached to the tip of an elastic spring rod supported on the ground. Japanese Unexamined Utility Model Publication No. Hei 5-70281 has a configuration in which a simulated bird is suspended. In this bird simulated bird, the simulated bird that has been subjected to the wind is moderately deformed by an elastic spring. It has a structure that aims to simulate the appearance of living simulated birds as if they were alive, and to surprise the birds and prevent them from approaching.
As disclosed in Japanese Patent No. 83, the fiberglass fishing rod attached to the upper part of the stand is decelerated and rotated by a motor for an automobile wiper, and further provided with an irregular timer. A sparrow, a crow dispelling machine, and the like, which are configured so as not to be caught and have a structure in which wild birds can be dispelled relatively quietly, have also been proposed.

Further, in the invention disclosed in Japanese Patent Application Laid-Open No. 10-248472, a ferromagnetic metal plate having a permanent magnet mounted thereon is hung on an upper end of a support member erected on the ground using a coil spring and a fishing line. The ferromagnetic metal plate receives wind and repeats irregular swings due to the elasticity of a coil spring to form an abnormal magnetic field in the vicinity. Outside with protective gear,
It features a technology that automatically and intermittently emits an intimidating sound in response to the frequency band of the starling's cry, so that it can efficiently threaten only when a starling approaches. Various prevention techniques have been developed or put to practical use, such as a harmful bird threatening device disclosed in JP-A-5-123093, and a known threatening device using a gas explosion sound.

[0005] However, these prior bird damage prevention technologies are:
All of them have been used by small animals including wild birds in a while, so they can not expect the threatening effect, or they will be affected by the complaints from neighboring residents, so that sufficient effects can not be expected. Therefore, the present invention provides an effective effect that does not cause any inconvenience to neighboring residents, because the preventive effect which cannot be realized by the conventional ones is maintained for a long time. Judging from the possibility that bird harm prevention technology could not be obtained, we started development and research quickly and repeated trial and error over a long period of time and numerous trial productions and experiments. The present invention has succeeded in realizing a bird's eyepiece, and the configuration thereof will be described in detail below, together with an embodiment representative of the present invention shown in the drawings.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be clearly understood from the embodiments of the present invention shown in the drawings, the bird guard included in the present invention basically has the following structure. That is, on the upper end side of a pillar portion of a predetermined height vertically set up on the ground, a rotary suspension portion which is rotatable around the axis of the pillar portion by an appropriate power source is arranged, and the rotary suspension portion is provided.

The gist of the present invention is a structure in which a raptor model body, which is light and lightweight and imitates a flying attitude, is attached.

[0007] In other words, the bird embedding tool included in the present invention can be basically configured as follows. On the upper end side of a pillar portion of a predetermined height vertically set up on the ground, a rotating suspension portion that is rotatable around the axis of the pillar portion by an appropriate power source is arranged, and the rotation of the rotating hanging portion is rotated. A suitable portion on the outer edge side is used as a support portion, and one end of a connection line portion of an appropriate length formed through an expansion / contraction mechanism portion is connected to an appropriate position in the middle to form a suspension shape, while the play end side is relatively lightweight. It is assumed that the raptor model body that imitates the flight attitude is attached, and the connecting line that operates following the rotation operation of the rotating suspension, the rotational force of the rotating suspension and the mass of the raptor model body and its This is a bird guard that has a configuration in which the expansion and contraction mechanism is actuated by interaction with wind pressure resistance and the like, so that the movement of the raptor model body resembles the flight posture of an actual raptor.

[0008] More specifically, the bird tool of the present invention having the above-mentioned basic structure is provided with a power source as needed at the upper end side of a column having a predetermined height standing vertically on the ground. A rotating suspension part that is rotatable around the axis of the part is arranged, and a suitable part on the rotating outer edge side of the rotating suspension part is used as a support part, via a twist preventing joint and a telescopic mechanism part at an appropriate place in the middle. While connecting one end of the connection line part of appropriate length to make it suspended, the raptor model, which is relatively lightweight and imitates the flight attitude, is attached to the free end. It will be.

[0009] The bird guard of the present invention has a wind receiving wing on the upper end side of a pillar portion of a predetermined height vertically erected on the ground, and the pillar shaft axis is powered by wind power. After arranging a rotating suspension part which can be turned around, a connecting line part of an appropriate length formed via a telescopic mechanism part at an appropriate place in the middle as a supporting part at a suitable position on the rotating outer edge side of the rotating hanging part. On the other hand, one end side is connected to form a suspension, while the play end side includes a structure in which a relatively light weight and a raptor model body imitating a flying posture is attached. In a different expression, the bird guard included in the present invention has a wind receiving wing on the upper end side of a pillar portion having a predetermined height vertically erected on the ground, A rotary suspension is arranged so as to be rotatable around the axis of the column using the wind power as a power source, and a rotary outer edge of the rotary suspension is provided at a suitable position on a rotary outer edge side. As a support portion, one end of a connection line portion of an appropriate length formed through an expansion / contraction mechanism portion at an appropriate position in the middle is connected to form a suspension shape, while the free end portion is relatively light and fly. By attaching the raptor model body that imitates the posture, the wind receiving wings that have received the wind rotate the rotating suspension part, and the rotational force of the rotating suspension part and the mass of the raptor model body side The bird's torch tool has a structure in which the expansion and contraction mechanism is actuated by interaction with the wind pressure resistance, etc., and the movement of the raptor model body is made to closely resemble the flight posture of the actual raptor. It is possible.

[0010] The support portion has a function of supporting the rotary suspension at a predetermined height position, and must support the rotary suspension so as to be rotatable around a predetermined axis.
While having enough strength to support the rotating suspension,
The base end shall be installed on the ground and shall be vertically erected, and shall be installed in arable land or orchards such as galvanized steel pipes or structural I- or H-shaped steel. Even inconspicuous,
It is desirable to have a shape that is easy to dissolve into the landscape, but it is a surface finish that has been subjected to processing such as glossy plating, painting or film sticking, and that can reflect sunlight and threaten birds It is also possible to use

[0011] Further, it is sufficient for the support portion to have a portion on the upper end side that rotatably supports the rotary hanging portion can be erected so as to maintain a vertical posture with respect to the ground.
It does not limit the shape of the middle part from the ground to the upper end side.For example, the upper end part is extended directly above the fruit tree, and it is erected in an inclined shape or bent in a crank shape. In addition to the above, a plurality of legs or a leg for enlarging the installation area may be provided to enhance the ground installation structure.

The rotary suspension has a function of suspending the raptor model body on the upper end side of the column so that the raptor can swing freely. The suspension must be capable of being appropriately rotated by receiving a driving force from a power source. Instead, it can be formed into a ring shape having a predetermined diameter centered on the support portion, one or a plurality of horizontal or obliquely upward or diagonally downward from the support portion,
It can be formed in a rod shape that is radially or in a branch shape, and is preferably formed from a relatively lightweight steel pipe or light metal pipe or the like that facilitates turning drive. A matte surface treatment that easily dissolves into the scenery or a surface finish that can sharply reflect sunlight and threaten birds can be used, and it is rotatably supported at the top end of the support section via a bearing structure as appropriate. Alternatively, it may be configured to be directly connected to a drive shaft of a drive motor provided on the upper end side of the column portion or via a speed reduction mechanism, and to turn by receiving a rotational driving force.

The power source has a function of rotating and driving the rotary suspension. The power source should be automatically driven to rotate without being operated by a person.
It shall be rotationally driven by the wind blowing naturally, and one wind receiving blade is provided to turn following the change in wind direction, or a plurality of wind receiving blades are provided in a windmill shape, In addition to being able to be configured to repeat turning continuously when receiving wind blowing,
A motor drive using a power source such as a battery or a solar cell can be used to drive the motor continuously or intermittently, or a combination of the two to pierce the two jointly, wind power has priority, and the power supply motor side complements it. It is also possible to use a timer to perform a turning drive at a preset time or to operate a switch in response to the sound of wild birds, which is a technology of arable land. It is also possible to use such a method.

[0014] The wind receiving wings perform the function of rotating and driving the rotating suspension part in response to natural wind, and endure strong winds.
The model must be strong enough to route the raptor model body, and should be lightweight enough to be able to turn, even in weak winds. It is desirable to have an area, and it is desirable to provide it on the rotating outer edge side which is the centrifugal side of the rotating suspension, and it is not limited to a specific shape, and the surface is provided with a display imitating eyes that threatens birds Or a permanent magnet attached or embedded or formed from a magnetic material.

The supporting portion serves to connect and support one end of the connecting wire portion, and should be provided on the outer peripheral side of the rotating suspension portion. The one formed around the outer peripheral edge of the hanging part, or near the centrifugal end of the rotating hanging part formed in a branch shape, or the wind receiving wing provided at the centrifugal side edge of the rotating hanging part. It is assumed that the connecting wire portion is formed from a connecting hole, a connecting ring portion, or a connecting metal fitting or the like that can firmly connect the connecting wire portion.

The connecting line portion has a function of suspending the raptor model body on the rotating suspension, and a material for securing the raptor model body with sufficient strength must be selected, so that it is conspicuous in the air. Instead, the raptor model should appear to be flying in the sky under its own power, and should be formed from a high-strength thin rod made of metal, carbon resin, or glass fiber resin. Although it is possible, it is desirable to select and adopt a relatively flexible thin wire material such as a piano wire, a metal wire, or a synthetic resin rope.

The expansion / contraction mechanism has a function of adding elasticity to the connecting wire portion, and must have such a strength as not to be plastically deformed or damaged by a strong wind. It should be relatively lightweight and small, and it is desirable to use a tension spring, a compression spring, natural rubber or a soft synthetic resin or the like as it is, but the elastic material is used for a link mechanism, a slide mechanism, etc. A structure in which a compressible gas is sealed in an intervening or cylinder having a piston, compresses the gas when subjected to tensile force, and restores the stretched shape when the tensile force is removed. Of course, it is also possible.

The joint for preventing torsion serves to prevent the torsion of the connecting wire portion. When one end of the connecting wire portion is fixed, the free end is rotatable and no torsion occurs. It must be structured so that one end side and the free end side of the connecting line are rotatably connected around the same axis, or even if they are inclined to the same axis and a predetermined angle range. It should be a flexible joint that can be freely connected, and it is most preferable to use a small, lightweight and inconspicuous sarkan.

The raptor model has a function of visually threatening small animals such as birds and rats, and should be light enough to fly in the presence of a breeze and have sufficient durability. There, the two wings stretched out and made a posture that made a turning flight in response to the rising air current, or the two wings were slightly narrowed and shaped into a posture that made a quick horizontal flight or a descent, or For the body part that balances horizontally, the front sides of both wings and tail wings are bent almost vertically downward, imitating a posture that is trying to land for prey and bent. It is extremely convenient to make the wings easily swing in response to the crosswind.

The raptor model body is formed by welding a relatively lightweight hollow synthetic resin molded product, a foamed resin molded product, or a synthetic resin sheet to form a bag and injecting air into the bag, or It is possible to adopt a sheet formed by punching a thick sheet or plate made of a synthetic resin.For example, a falcon, a goshawk, a golden eagle, a crowned eagle, a Norris, and the like are formed into a model very similar to a real bird of prey. However, a model having characteristic beaks, eyes, wings and the like, and which can be recognized as a kind of bird of prey from a distance may be used.

The raptor model body may be provided with a permanent magnet on the inner or outer surface side.
It can be installed on the head or torso, or scattered throughout the body.In addition, the entire model can be manufactured as a composite material made of synthetic resin with a magnetic material added. It can be coated with a paint or synthetic resin film containing the material.In addition, it is not completely integrated or embedded in the raptor model body, but becomes floating at the place of attachment. Appropriate structure, for example, a structure in which a magnet is simply housed in a case integrated with the raptor model body side, or attached to the tip of a wing that fluctuates due to wind, or a coil spring protruding to resemble a foot, Of course, there is no problem even if it is a structure attached to it or another application of a known floating structure.

Further, the bird embrace included in the present invention is:
A power controller, an audio board, an amplifier, a speaker, a battery power source and / or a solar cell can be disposed in place on the support, and the raptor can automatically generate a crowing sound to the surroundings at a predetermined time in daytime. A sound generator may be incorporated. In the following, the structure of the present invention will be described in detail, together with the embodiment shown in the drawings.

[0023]

The pillar 1 is made of a steel pipe which has been subjected to rust-proofing by galvanizing or coating as appropriate. The base end is buried to a predetermined depth in the ground, or the base is cast on the ground. The part is connected via a joint structure through a flange part, or a joint structure by welding, etc., is erected vertically, and has a total height set to about 4 to 5 m. The base end side of the rotary hanging part 2 bent in an L-shape and formed in a branch shape is mounted via a bearing part (not shown), is rotatable around the axis of the support part 1, and has a radius of rotation. Is set to about 1 to 1.5 m, and at the tip of the rotation outer peripheral end, at the center of the front and back faces oriented horizontally,
An arrow blade-shaped wind receiving wing 21, which is affixed with a double circle for reflection by a reflective film and is displayed, is integrally fixed, and a lower edge of the wind receiving wing 21. Is formed with a support portion 22 formed of a through hole to which one end of the connection line portion 3 can be connected.

The support portion 22 is composed of a sarkan forming a twist prevention joint 31, a tension coil spring forming an expansion / contraction mechanism portion 32, and a metal wire rope or a piano wire 33 from one end side to the free end side. One end of the connecting wire portion 3 having a total length set to about 30 to 40 cm is connected, one end of the sarkan 31 is connected to the support portion 22, and the metal wire rope 3
3 is connected to the back of the raptor model body 3.

The bird of prey model 3 is made of a relatively lightweight synthetic resin molded article of a falcon, which is one of typical birds of prey, or a synthetic resin sheet in which a bird body is printed in color in advance. Is welded in a bag shape and filled with air or other gas, a granular material made of foamed resin, or a material that can be stuffed relatively easily, such as sponge, into a model that resembles a falcon, and furthermore, inside A permanent magnet having a strong magnetic force (not shown) is embedded or encapsulated and fixed.

A sound generator 5 having a box-shaped main body is mounted and fixed to the upper halfway portion of the column 1 with a metal fitting as appropriate. A battery 51 is provided in an exposed state, and a battery power supply 52, a power supply controller 53, an audio board 54, an amplifier 55, and a speaker 56 are provided inside. The power supply controller 53 is exposed outside the box-shaped main body.

The current from the battery power supply 52 is supplied to the audio board 54. The sound board 54 is provided with a function of reproducing the sounds of a plurality of birds of prey, and has a manual channel that can select any of the sounds. A cry of a raptor (a falcon) selected by a manual channel is generated and sent to an amplifier 55, and a loud sound is generated through a speaker 56.

Further, as shown in the configuration diagram of the sound generating device in FIG. 3, the sound generating device 5 can use a dry battery as a power source. (Comprising a group of AA batteries)
The dry battery 57 can be exchangeably connected.

[0030]

According to the bird guard of the present invention having the above-described structure, the strut 1 is vertically driven on the ground such as a field or an orchard as shown in FIG. A sound generator 5 is attached to the upper halfway, and a rotary suspension 2 is rotatably mounted on the upper end of the column 1, and a sarkan 31 and a coil spring 3 are mounted on a support 22 of an arrow-shaped wind receiving blade 21.
2, and the raptor model body 4 is suspended via the connecting line portion 3 composed of the wire rope 33, the wind receiving wings 21 catch the wind blowing around, and the rotating suspension portion 2 is rotated around the axis of the support portion 1. The connecting line portion 3 which has received the turning movement force of the rotary suspension 2 forcibly turns the raptor model body 4, and the raptor model body 4 to be turned around has its wings. Is moved in a swirling manner while taking a flying attitude while receiving air resistance. Also, when the raptor model body 4 is pulled and moved, the coil spring 32 forming the expansion / contraction mechanism is elastically stretched, and the raptor model body 4 finishes turning. When the air resistance applied to the wings is weakened, the coil spring 32 exerts a restoring force to pull back the raptor model body 4, and as a result, the raptor model body 4 moves in a trackless manner around the column 1. Such continuous movement is repeated while smoothly changing the flight speed.

The sulkan 31 as a torsion preventing joint provided between the support portion 22 of the wind receiving blade 21 and the coil spring 32 receives a continuous flight movement in a trackless manner,
The connecting line portion 3 becomes entangled, and prevents the raptor model body 4 from causing an unnatural spinning motion due to the return, and the bird's wings 21 displayed on the front and back of the wind receiving wing 21 are prevented. The heavy circle reflects the natural light, and reflects the sunlight in a blinking manner with the rotation of the rotary hanging part 2. Furthermore,
The permanent magnet (not shown) built in the raptor model body 4 always generates a magnetic field within a predetermined radius range of the raptor model body 4 and generates a magnetic field every time the raptor model body 4 moves in a swirling manner. It will be moved tracklessly.

[0032] The sound generating apparatus 5 configured as shown in FIG.

To reproduce the call of a bird of prey (falcon) selected in advance by a manual channel, and receive the reproduced signal.
Will generate a sound that is loudspeaked around through the speaker 56. Also, as shown in FIG. 3, if a plurality of dry batteries 57 are installed instead of the solar battery 51 and the battery power supply 52, the dry batteries 57 are periodically replaced, and the same The sound of birds of prey can be reproduced.

[0033]

[Effects] As described above, according to the bird power tool of the present invention,
A raptor model that rotates and receives a rotational force from the drive source as appropriate, while stretching the telescopic mechanism, pulls the raptor model body in flight attitude to apply centrifugal force, and turns and returns. The body turns smoothly while changing the turning direction greatly due to the stability of the telescopic mechanism, and it seems as if wild birds of prey are willing to pursue their prey, dancing and jumping vigorously. In addition, their flight attitudes change every time and continue to reproduce the state close to nature at any time.Thus, threaten small animals such as wild birds and rats that approach the vicinity for a long time and keep chasing away. The excellent feature that can be obtained.

Further, by providing a twist preventing joint at the connecting line portion, it is possible to prevent an unnatural rotation of the raptor model body during flight and to make it possible to move more smoothly and quickly so that the fear of small animals can be prevented. It will be able to inspire the heart, and furthermore, by providing wind receiving wings on the rotating suspension, it will repeat the irregular turning by receiving the wind blowing naturally without the need for a special drive source As a result, the raptor model body can be promoted in an orbitless flight movement, and the effect of repelling small animals can be significantly enhanced.

In particular, the bird guard described in the embodiment is a rotary hanging part 2 in which a vertical part corresponding to a part of the support part 1 and an upper end thereof are bent substantially horizontally at the upper end of the support part 1. And a rotatable hanging part 2 with respect to the support part 1 can be easily attached and detached. Exchange,
In order to make it easier to use or to adapt to the height of the fruit tree, it is possible to prepare several types of hook-shaped members, suspend the raptor model body 4 at an appropriate height, and use it. Practical effects will be obtained if it is advantageous for handling operability.

Further, by using the sarkan 31 for the torsion-preventing joint and the coil spring 32 for the expansion and contraction mechanism, the size and weight can be reduced, and the flying movement of the agile raptor model body 4 can be facilitated. In addition to these features being inconspicuous, they would be very advantageous in convincing small animals to be wild birds of prey, in addition to having the advantage of being displayed on the front and back surfaces of the wind wing 21. The double circle for birds reflects natural light, blinks with the rotation of the rotary suspension 2, and gives the illusion of the small animal illuminating the eyes of an unknown large animal. It has the effect of becoming something.

Further, since the permanent magnet buried in the body of the raptor model body 4 moves together with the turning of the raptor model body 4, an abnormal magnetic field is generated to disturb the magnetic field sensing ability of the birds. As a result, there is an effect that wild birds hate them and it is difficult to approach them, and furthermore, the sound generation device 5 causes the same falcon to sing from the vicinity of the raptor model body 4 that models a falcon that is turning. And the small animals such as wild birds and rats that are distant from the voice reach the sound, and the effect is that the birds and the birds of prey in the direction of the small animals can be driven further. The fruit trees grow in the fields and orchards, so they can repel the existence of fruits growing in the fields before they realize it. The ones Xiu the advantage of being able to minimize the damage caused by small animals, such as starlings to be Muragaro to.

As described above, the bird-watching device of the present invention can achieve its intended purpose by its novel structure, is easy to manufacture, and has a large driving device and explosive sound. Since it does not require any equipment to generate noise, it is economical because it can be kept at a unit price that is approximately the same as that of conventional birds and birds, and it causes noise to nearby residents due to noise problems. If there is no fear, there is an advantage that the installation work can be relatively easily completed, etc., and it is possible to surely achieve cost reduction and work efficiency for bird damage prevention measures. To do
It is highly evaluated not only by farmers who have suffered damage to crops by small animals, but also by the general public who suffers from the damage of buildings and outdoor facilities due to nesting and dung, and has been widely used as a bird damage prevention tool. It is expected to be used and spread.

On the other hand, on the side of the play end, a relatively lightweight and raptor model body that imitates the flying attitude was attached, so that the wind receiving wing that received the wind It turns, and the expansion and contraction mechanism is operated by the interaction between the rotating force of the rotating suspension and the mass of the raptor model body and its wind pressure resistance, etc., so that the movement of the raptor model body is like the flight of a real raptor. A torture tool characterized by having a posture very similar. 6. The rotary suspension comprises a hook-shaped member in which an upper end side of a vertical portion corresponding to a part of a column is bent at an appropriate angle, but is not realized by the bent portion. The lower end of the hook-shaped member is rotatably connected to the upper end of a pillar having a predetermined height vertically erected on the ground. Any of the bird-watching tools described. 7. A rotary suspension, a connecting line, a raptor model body, or one or two of them,
The bird guard according to any one of claims 1 to 6, wherein the permanent magnet is fixed or variably fixed. 8. A power controller, an audio board, an amplifier, a speaker, a battery power source, and / or a solar cell are arranged at appropriate positions on the support portion, and the raptor's cry is automatically directed to the surroundings at a predetermined time in daytime. 8. A sound generator which can be generated in an integrated manner.
