Abstract

PROBLEM TO BE SOLVED: To solve such a problem that birds stop on the electric cables or wires, since a conventional bird repellent has no moving or movable elements and the birds are on their guard at the beginning but they become habituated to it before long and stop on the cables and wires. SOLUTION: This bird repellent device 2 is constituted of a base body 3 firmly fixed to the wire 1 and a rotor 4 that is loosely fitted to the firmly fixed base body. Accordingly, the loosely fitted rotor 4 is freely rotatable around the firmly fixed base body 3 as the rotation center. In addition, the rotor 4 is equipped with blades in the radial direction and is made readily rotatable by the wind blow. When a bird tries to stop on the bird-repelling device, the rotor promptly is rotated by the weight of the bird and it cannot stay long on the device 2. When the wind blows, the rotor continuously rotates to always change the whole shape offensively to the birds, thereby the birds are forced to be on guard and not habituated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird repelling device attached to an electric wire to prevent a bird from stopping on the electric wire.

[0002]

2. Description of the Related Art When birds stop on electric wires, they often drop feces there. There is no problem if the place directly below the electric wire is a field or a field, but if it is a veranda where you can dry clothes or a place where many people gather (eg, a bus stop, a taxi waiting place) The harm of falling droppings is a problem. Therefore, conventionally, various bird repelling devices for preventing birds from stopping on the electric wire have been considered.

FIG. 7 is a diagram showing a first conventional example of such a bird repelling device. In FIG. 7, 1 is an electric wire, 2 is a bird guard, 51 is a projection, and 52 is fixing means. The bird guard device 2 is configured by attaching a protrusion 51 to the electric wire 1 by a fixing means 52. Protrusion 5
1 is attached so that its protruding direction is directed upward from the electric wire 1. As the fixing means 52, for example, a means capable of being fastened such as a wire or a band is used. Such a bird repelling device 2 is attached to a portion of the electric wire 1 at a portion where the bird does not want to stop (for example, a portion above the veranda) with an interval that seems to hesitate to stop the bird. Can be

FIG. 8 is a diagram showing a second conventional example of a bird repelling device. The reference numerals correspond to those in FIG. 7, 53 is a stay (support), 54 is a wire, and 55 is a fixing means. The bird guard device 2 is configured by attaching a plurality of stays 53 to the electric wire 1 by fixing means 55 and stretching a wire 54 between the adjacent stays 53. The wire 54 may be much smaller than the electric wire 1 because the wire 54 may be of such a size that the bird does not get in the way when stopping on the electric wire 1 and gives up stopping. This bird repellent device 2
After all, attach it to the electric wire part that you do not want the bird to stop. As described above, conventionally, birds are prevented from stopping by attaching the bird repelling device 2 as shown in FIGS. 7 and 8 to the electric wire 1.

[0005]

[Problem to be Solved] (Problem) The above-mentioned conventional bird repelling device has a problem that the bird repelling effect is attached for a short time after being attached to an electric wire, but is ineffective thereafter. Was. (Explanation of the problem) The cause is not clear, but judging from the result of the observation, the cause is that the conventional bird repelling device has no moving parts and its shape is always the same fixed. There seems to be.

That is, for a while after the bird guard is attached to the electric wire, the shape of the electric wire portion to which it is attached is different from before, so that the bird does not stop with caution. . However, if it turns out that the shape is the same regardless of when it flies, and it does not perform any aggressive action against birds, the birds will become accustomed and will not be vigilant. Eventually, even if there is a bird repelling device, it will stop. An object of the present invention is to solve the above problems.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a bird is prevented from stopping on an electric wire.
In a bird guard device attached to an electric wire, a cylindrical body having a C-shaped cross section formed of an elastic material and having a first cut portion in a cylindrical direction, and a cylindrical body formed of an elastic material, and having two ends at both ends of the cylindrical body A fixing base, which is provided with a flange provided and is fixed by being fitted to an electric wire by opening the first cut portion, and a play having a C-shaped cross section formed of an elastic material and having a second cut portion in a cylindrical direction. A loosely-fitting rotary body comprising a fitted cylindrical body portion and a blade portion planted on an outer surface of the loosely fitted cylindrical body portion, wherein the second cut portion is opened and loosely fitted on the outer periphery of the fixed base. And a configuration that includes The brim portion may be constituted by a plurality of separated brim pieces. The opposite end of the second cut portion of the loosely fitted cylindrical body may have a cut edge smoothly folded back.

(Summary of operation to be solved) When a bird tries to stop on the bird repellent device of the present invention attached to an electric wire, there is no stopping other than the blade portion of the loosely fitted rotating body. But,
When the bird stops there, the loosely-fitting rotator rotates around due to the weight of the bird, and the bird cannot stop still. Further, when the wind blows, the loosely-fitting rotating body rotates around the fixed base by the force of the wind hitting the blade. The manner of rotation may be intense or slow depending on the force of the wind. That is, the bird repellent device of the present invention has a moving part, and has an appearance that varies from time to time. Therefore, for a bird, the object is reflected as an object having a different shape each time, and a sense of caution can be maintained forever.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a bird repellent device according to the present invention. The symbols correspond to those in FIG.
Reference numeral 3 denotes a fixed base, and 4 denotes a loose fitting rotating body. This figure shows an outline of the configuration of the bird guard device 2 of the present invention. That is, the bird repelling device 2 of the present invention is composed of two large components, that is, the fixed base 3 and the loosely fitted rotator 4. The fixed base 3 is a component that is directly attached to the electric wire 1, and the loose fitting rotator 4 is a component that is loosely fitted to the fixed base 3. Therefore, the configurations of the fixed base 3 and the loosely-fitting rotary body 4 will be described in detail, and then the entire configuration of FIG. 1 will be described.

FIG. 2 is a view showing a fixed base 3 constituting the bird repelling device of the present invention. 31 is a collar, 32 is a cylindrical body, 33 is a through hole, and 34 is a cutout. The cylindrical body portion 32 has one cut portion 34 in the cylinder direction, and the cross section of a plane perpendicular to the cylinder direction is C-shaped.
Accordingly, the cylindrical body 32 is cylindrical as a whole, but is not strictly a cylinder. The inside of the cylindrical body 32 is a through hole 33. The flanges 31 are provided at both ends of the cylindrical body 32. A portion corresponding to the through-hole portion 33 is an opening, and is cut open outward from a portion of the flange portion 31 facing the cut portion 34.

The fixed base 3 (the flange 31, the cylindrical body 3)
A material that is robust and has elasticity is used as a member constituting 2). For example, metal or plastic. The fixing base 3 is directly attached to and fixed to the electric wire 1. When the fixing base 3 is attached, the cut portion 34 is opened so as to have a large opening degree, and a side portion of the electric wire 1 is pressed against the cut portion 34. Attach by Since the fixing base 3 is distorted and attached in this manner, it is necessary to have elasticity. FIG. 4 is a diagram showing a state in which the fixing base 3 is attached to the electric wire in this manner.

The inner diameter of the cylindrical body 32 is set to be substantially equal to or slightly smaller than the outer diameter of the electric wire 1, and the material of the cylindrical body 32 is made of a material having strong elasticity.
Can be held firmly only by elastic force. However, after holding the electric wire 1 lightly, it is also possible to use other means to secure the holding. For example, after holding lightly, a pressing force may be applied from the outside to secure the holding. Further, it can be fixed using a band, a hook, a detachable tape or the like.

FIG. 3 is a view showing a loosely fitted rotating body 4 constituting the bird repelling device of the present invention. 41 is a blade portion, 42 is a loosely fitted cylindrical body portion, 43 is a through hole portion, and 44 is a cut portion. The loosely fitted cylindrical body 42 has the same shape as the cylindrical body 32 described above, has one cut portion 44 in the cylinder direction, and has a C-shaped cross section in a plane perpendicular to the cylinder direction. It has been.
The blade portion 41 is formed of a flat plate which is planted with a cylindrical straight portion on the outer surface of the loosely fitted cylindrical body portion 42 as a base, and whose tip extends in the radial direction. A plurality of blades 41 are provided on the outer surface of the loosely fitted cylindrical body 42. The positions are desirably provided at regular intervals in consideration of balance.

The members forming the loose fitting rotary member 4 are made of a rigid and elastic material, similarly to the fixed base 3. As shown in FIG. 4, the loose fitting rotator 4 is loosely fitted on the outer periphery of the fixed base 3 attached to the electric wire 1. The loose fitting is performed by opening the cut portion 44 in FIG. 3 so that the degree of opening is large, and fitting the outer periphery of the cylindrical body 32 of the fixed base 3. It is designed so that a gap is formed between the outer surface of the cylindrical body 32 and the inner surface of the loosely fitted cylindrical body 42 in the fitted state (that is, the loosely fitted state). That is, the inner diameter of the loosely fitted cylindrical body 42 is set to be sufficiently larger than the outer diameter of the cylindrical body 32. However, it is set smaller than the outer diameter of the collar portion 31. This is because the torso portion 31 is to prevent the loosely fitted rotating body 4 from coming off the fixed base 3 in the first place. Of course, in order to prevent the loose-fitting rotary body 4 from coming off, the size of the gap in the normal state of the notch 44 should not be large enough to pass through the cylindrical body 32. I do.

When assembled as described above, the bird repelling device 2 of the present invention as shown in FIG. 1 is obtained. In this bird guard 2, the fixed base 3 is fixed to the electric wire 1 and therefore does not move.
It is easily rotated because it is only loosely fitted to the. That is, the bird guard device 2 of the present invention has a structure having a moving part. For example, the bird tries to stop at the wing portion 41, and turns around with the weight of the bird, and the bird cannot physically stop. In addition, when the wind blows, it rotates violently or slowly according to the force of the wind, so that the appearance of a sudden change is exhibited. For a bird, this will appear as an object of a different shape each time,
You can have a sense of security forever. In particular, if the wings 41 are made to have a mirror finish that occasionally reflects sunlight, or a surface having a unique color or pattern, it is possible to further raise a sense of caution.

FIG. 5 is a view showing another example of the fixed base 3. A different point from the fixed base 3 in FIG. Although the brim portion 31 of FIG. 3 was configured by one plate material,
The collar 31 of FIG. 5 has several separate collar pieces 31A.
It is assumed to be composed of FIG.
It is a figure showing other examples of. The difference from the loose fitting rotary member 4 in FIG. 3 is that the opposite ends of the cut portion 44 are each an end having a cut edge portion 45 that is smoothly folded back. In this way, when performing the operation of fitting the loosely-fitting rotating body 4 to the outer periphery of the fixed base 3, the folded cutting edge 4
The portion 5 serves as a guide for fitting, and the work becomes easier.

[0017]

As described above, according to the bird repellent device of the present invention, the following effects can be obtained. Physically preventing the bird from stopping If the bird tries to stop on the electric wire part where the bird repelling device of the present invention is attached, the loosely fitted rotator will rotate with the weight of the bird, and the bird will physically stop. I can't stop.

Prevents the bird from getting used to. It has a loose-fitting rotating body as a moving part, and its whole shape constantly changes due to wind force. For this reason, the bird does not become accustomed to the bird, and can always be alert. Demonstration of aggressive action on birds When the loose-fitting rotating body makes a noise even with the wind, the sound exerts an aggressive action that makes it seem that it is a harbinger to the birds. I do.
If the wings are mirror-finished so as to reflect sunlight, or if they are given a unique color or pattern, they have the effect of surprising birds and keep them away from electric wires.
