[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing birds such as pigeons from entering a veranda or the like.

[0002]

2. Description of the Related Art In recent years, birds such as pigeons, crows, sparrows, and starlings that inhabit cities have increased, and excreted feces and pathogens have become a problem. For example, a method using a false eye, a needle, an ultrasonic wave, or the like has been proposed in order to prevent the above problem. Among them, bird repellent devices that use magnets, focusing on dislikes strong magnetism that disturbs the biomagnetism of birds themselves (which judge the direction of flight and are signs of homing) Have been proposed, and for example, an apparatus disclosed in Japanese Utility Model Publication No. 4-10789 is known.

[0003]

However, a method of simply attaching a plurality of hemispherical magnets at predetermined intervals to a tension line as in the invention disclosed in this publication has a certain degree of effect, but has a certain effect. However, there is a problem that satisfactory results cannot be obtained for the user, for example, the pigeon is insensitive to the above, and stops at the tension wire between the hemispherical magnets. The present invention has been made in view of the above-described conventional problems, and has as its object to provide a bird repellent device that can efficiently and reliably prevent birds such as pigeons from entering a veranda or the like.

[0004]

According to the present invention, in order to achieve the above object, a support and a central portion fixed to an upper portion of the support are provided.
Consists of a mounting girder arm, it swingable fulcrum central portion of the arm is provided with a magnetic body on both ends of the arm
It is configured as follows. The arms may be provided in an upper limit of two or more stages, or may intersect at an arbitrary angle of two or more arms on the same plane. Also in these cases, magnetic bodies are provided at both ends of each arm. Note that the magnetic body may be provided not only at both ends of the arm but also at the center, and the column and / or the arm may be formed by a coil spring. In addition, this device
Not only one device but also a plurality of devices may be arranged on a straight line without any gap, or a plurality of devices arranged in series may be further arranged at predetermined intervals.

[0005]

According to the present invention, a magnetic body is attached to both ends of an arm swingably supported on a single support, so if this device is installed on, for example, a handrail of a veranda, a bird that dislikes magnetism can be used. Can be prevented from approaching. Also, even if a bird insensitive to magnetism tries to stop between the magnetic bodies of the arm, the bird will be surprised to escape because the arm swings with respect to the support. In addition, when the column and / or the arm are formed of a coil spring, there is an advantage that the column and / or the arm swing more. Also, if the apparatus is installed in a straight line at that time, if one bird approaches the arm and swings, the magnetism will fly around and other birds will not approach, and other devices will not approach. The arm also swings simultaneously by magnetism, so that the bird is surprised and has the effect of not approaching other devices.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a bird repellent device according to the present invention, and FIG. 2 is a partially enlarged sectional view thereof.

In these figures, reference numeral 1 denotes a column such as a bolt, a round member, a square member, a plate, and the like. Reference numeral 2 denotes an arm which is mounted on an upper portion of the column 1 in a horizontal direction. Is supported so as to be able to swing freely at the intersection 3 with the arm, so that the bird stops on the arm, flutters the bird, or swings up and down and left and right due to the wind generated by nature. It is configured. Reference numerals 4a and 4b denote magnetic bodies provided at both ends of the arm 2, and a magnetic body 4c may be provided at the fulcrum 3 if necessary. The length of the arm 1 and the weight of the magnetic bodies 4a and 4b are configured to be balanced.

[0008] The pillar 1 is a place where birds do not want to be stopped and dung, for example, a railing 5 on a veranda of a residential apartment, a roof of an apartment or a temple, a panapet on a building roof, a light top of a street tree, a mat of a small boat. Adhesive on top of mercury lamp, etc.
Fix with screws, bolts, etc. In the illustrated example, known simple attachment / detachment tools 6a and 6b are illustrated. In addition, the height of the strut 1 should be changed according to the type of bird.
For m and crows, it is preferably about 20 cm. For this reason, in the case of a relatively large bird such as a crow, it is desirable to arrange the arms in two stages, 2A and 2B, as shown in FIG. The length of the arm depends on the number of magnetic bodies to be attached. However, when the arm is attached at three places at both ends and at the center as shown in the illustrated example, the length is about 30 to 40 cm. The magnetic force is such that the bird feels the magnetism and affects the biomagnetism of the head.
000 gauss or more.

As a method of mounting the bird repellent device,
First, dust, oil, bird droppings, etc. on the surface of the installation place (for example, the veranda handrail 5) are thoroughly cleaned, and one of the known simple attaching / detaching tools 6b is provided on the handrail in advance. The other attachment / detachment tool 6a is provided on the base 7 and attached. This has the advantage that it can be easily removed when unnecessary, such as when drying the futon on the veranda. It is also desirable to install a plurality of the present apparatuses on a straight line without any gap. In this case, if the adjacent magnetic bodies 4a and 4b have the same magnetic pole (positive or negative) (see FIG. 1), there is an advantage that they repel each other and swing more.

When the bird repellent device according to the present embodiment configured as described above is installed, the birds dislike magnetism.
Keep away from a-4c. Also, even if a bird insensitive to magnetism tries to stop on the arm 2, the arm 2 swings up and down and left and right with respect to the support 1, so that the arm shakes and flies away surprisingly. Further, when the magnetic body swings, the magnetism flies to the surroundings, and the surrounding magnetic field fluctuates and becomes an abnormal magnetic field.

FIG. 4 shows a second embodiment of the present invention, in which the columns and / or arms are made of coil springs 1C and 2C and other elastic materials. The use of a coil spring swings more greatly, so that there is an advantage that the repelling effect can be enhanced.

FIG. 5 shows a third embodiment in which two or more arms 2D, 2E... Cross at an arbitrary angle .alpha. The magnetic members 4a and 4b are provided at both ends in the same manner as described above. In this embodiment, two or more steps may be used as shown in FIG.
Of course, D, 2E... May be a coil spring or another elastic material. FIGS. 7 and 8 show a case in which a rotary bird guard 8 is provided on a plurality of arms, an eye pattern 9 such as a bird of prey is formed on the bird guard 8, and a magnetic field is formed at an arbitrary position. This is an example in which a body 10 is provided. In this example, not only the magnetism of the magnetic body 10 but also the birds can be scared by the eye-shaped crests 9, and since they rotate, the repelling effect is further enhanced. Further, the bird-watching tool 8 is not limited to the cross shape as shown in FIG. 7, but a plurality of eye-marks 12 are formed on the bird-watching tool 11 inflated in a balloon shape as shown in FIG. It may be something.

FIGS. 10 and 11 show an example in which the present apparatus is installed on a bay window 14 or a building roof 15. Birds generally tend to stop on the bay window 14 or the building roof 15, and are easily contaminated with feces. For this reason, if this device is installed, birds can be reliably avoided. Although the repelling device of this embodiment is exemplified by those shown in FIGS. 2 and 5, it is needless to say that other embodiments shown in FIGS. 3, 4, 6, 7, and 9 can be implemented. .

[0014]

[Effects of the Invention] As described above, the present invention includes a support,
An arm fixed at the center at the top of the support, and a magnetic body is provided at both ends of the arm to secure the arm.
It was constructed so that it could swing around the center.
In this way, you can avoid birds that dislike magnetism. Also, even if a bird insensitive to magnetism tries to stop on the arm, the arm swings up and down, left and right, and flies away surprisingly because the arm is swingably attached to the support. The magnetic field of the near zone shakes the magnetism flying around the Ru which no further or birds closer than abnormal next <br/>. Furthermore, since the support column is formed by a coil spring, the size of the support column is increased by the rotation range of the arm and the magnet, so that birds such as pigeons can be more efficiently prevented from entering the veranda or the like.
