Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird damage preventive tool used in advance to prevent bird damage such as fecal damage caused by a bird staying on an electric wire.

[0002]

2. Description of the Related Art With the progress of urbanization, the number of trees that can be used as bird residences and bird rest areas has decreased, and electric wires have become a perch for birds, but many birds stop on electric wires. In the place, problems such as fecal damage and cutting of electric wires due to the weight of birds have occurred. Therefore, in order to eliminate such bird damage, for example, FIGS. 7 and 8 are disclosed in Japanese Utility Model Publication No. 3-83426.
A bird damage preventive tool 100 as shown in 1 has been proposed.

This bird damage preventive device 100 is shown in FIGS.
As shown in FIG. 2, the electric wire surrounding portion 101 and a large number of needle-like bodies 102 projecting outward from the electric wire surrounding portion 101 are provided, and a cut 103 formed in the electric wire surrounding portion 101.
When the electric wire surrounding portion 101 is mounted so as to surround the electric wire 104 as shown in FIG.
The needle-like bodies 102 are provided so as to project around the wire 4, thereby eliminating the place where the bird can be grasped and preventing the bird from stopping on the electric wire 104.

[0004]

However, the bird damage prevention device 100 is bulky and very inconvenient during transportation because the wire surrounding portion 101 has a structure in which a cut 103 is formed in an elastic cylindrical body. is there. Further, the electric wire 104 is erected, and the mounting work must be performed at a high place, but the work of pushing the slit 103 wide against the elastic force is very unstable and dangerous.

Further, even if the birds 100 can be prevented from stopping on the electric wire 104 by using the bird damage prevention device 100 as described above, instead of the electric wires 104, the birds can be stopped on the roof of the house or the handrail of the balcony. There is also a problem that bird damage will occur in a new place.

In view of such circumstances, the present invention provides a bird damage preventive device which is easy to carry and mount on an electric wire and which can also be used for preventing bird damage at a place other than the electric wire. It is an object.

[0007]

In order to achieve such an object, a bird damage prevention device according to the present invention has a large number of needle-shaped bodies protruding from one side surface of a synthetic resin plate having a desired thickness. A plurality of grooves are provided in parallel on the other side surface of the synthetic resin plate, and the synthetic resin plate is bent with the acicular body side facing outward at the thinned portion due to the formation of the grooves,
The configuration is such that it can be transformed into a tubular shape.

In the above structure, although not particularly limited,
The material of the synthetic resin plate is not particularly limited, but polyethylene resin is preferable. Further, it is preferable to provide a connecting means that can be connected to another flat plate-shaped member of the same kind at the longitudinal end portion of the flat plate-shaped member.

The needle-shaped body needs to have a certain degree of rigidity so that it will not be bent or bent even if a bird is placed on it.

[0010]

According to the above structure, if the two bird damage prevention tools are stacked so that the sides on which the needle-shaped bodies are provided are aligned, they can be stacked without being bulky. Also, arrange the side of the synthetic resin plate on which the needles are not provided along the electric wire, and hold both ends in the width direction so as to surround the electric wire and bend it to the side on which the needles are not provided. Then, the synthetic resin plate becomes a tubular shape and completely surrounds the electric wire.

Then, the engaging means and the engaged means provided at both ends in the width direction are engaged with each other, or a belt-like fixing member is tightened and fixed from the outside of the cylindrical body to form a synthetic resin plate. While being held in a tubular shape and attached to an electric wire, needle-like bodies are projected radially around the tubular body, so that a bird cannot hold the tubular body and stop.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments thereof. 1 and 2 show an embodiment of a bird damage prevention tool according to the present invention.
As shown in FIGS. 1 and 2, the bird damage prevention tool 1 includes a synthetic resin plate 2 and a large number of needle-shaped bodies 3 ... 3, and a flat plate-shaped member 2 and a large number of needle-shaped bodies 3 ...・ 3 and 3 are integrally molded by polyethylene resin.

As shown in FIGS. 1 and 2, the synthetic resin plate 2 has needle-like bodies 3 ... 3 projecting from one side surface at equal pitches. Through-holes 21 ... 21 are provided in the space between them to reduce the weight. In addition, as shown in FIG. 2, the synthetic resin plate 2 has a plurality of grooves 22 ... 22 extending parallel to the longitudinal direction on the other side surface not provided with the needle-shaped bodies 3. It is provided.

That is, by forming the groove 22 in the synthetic resin plate 2 having a large thickness and poor flexibility, as described above, the thick portion passes through the bottom portion 22a of the groove 22, that is, the thin portion. It becomes a shape that is connected. Then, the groove 2 which is thinned with the needle-shaped body 3 side as the outer side to give flexibility is formed.
When bent at the bottom 22a of the second synthetic resin plate 2, the synthetic resin plate 2 is deformed into a tubular shape.

Further, on one side in the width direction of the synthetic resin plate 2, two protrusions 23, 23 project outward.

The protrusion 23 has a hook-like barb 23a at its tip and a slit 23b at the center. Engagement holes 24, 24 are provided on the other side in the width direction of the synthetic resin plate 2 at positions corresponding to the protrusions 23, 23.

The engagement hole 24 is formed in such a size that the tip of the projection 23 can be press-fitted therein. Also, this synthetic resin plate 2
Has two cone-shaped projections 25, 2 at one end in the longitudinal direction.

A hole 26 with which the projection 25 is engaged is provided at a position corresponding to one of the projections 25 of the 25, and an elongated hole 27 into which the projection 25 is fitted is provided at a position corresponding to the other projection.

Since the bird damage preventive tool 1 is constructed as described above, when not in use, the two bird damage preventive tools 1 can be superposed so that the needle-like bodies 3 face each other. That is, if done in this way, one of the bird damage prevention tools 1
The needle-shaped body 3 of the other is the needle-shaped body 3 and the needle-shaped body 3 of the other bird damage prevention tool 1.
It can be stacked between and without being bulky.

Of course, in this bird damage preventive tool 1, as shown in FIG. 3, the synthetic resin plate 2 is provided in the groove 2 so that the needle-shaped body 3 is on the outside.
If the tip end of the protrusion 23 is press-fitted into the engagement hole 24 and engaged with the synthetic resin plate 2, the synthetic resin plate 2 is held in a tubular shape and the electric wire 4 is surrounded by the tube. It can be attached to any shape. The protrusion 23 has a slit 2 at the tip.
Since 3b is provided, when press-fitted into the engagement hole 24,
The return bar 23a bends inward at one end and smoothly enters the engaging hole 24. When the return bar 23a passes through the engaging hole 24, the return bar 23a returns to its original position due to the elastic restoring force, so that the return hole 23a is firmly engaged with the engaging hole 24. It is supposed to be done.

As shown in FIG. 4, the other bird damage preventive tool 1 is attached to the projections 25 provided at one end of the previously installed bird damage preventive tool 1 in the longitudinal direction. If the hole 26 and the long hole 27 provided at the other end in the longitudinal direction of the electric wire 4 are attached to the electric wire 4 one after another while engaging with each other, as shown in FIG.

Moreover, in this bird damage preventive tool 1, the groove 22 is provided from the surface where the needle-shaped body 3 is not provided toward the needle-shaped body 3 side to form a thin-walled portion, and the thin-walled portion forms the synthetic resin plate. 2 is made flexible so that the synthetic resin plate 2 can be wound around the electric wire 4 in a tubular shape.
The bottom portion 22a of the above does not directly contact the electric wire 4. Therefore, the bird damage prevention tool 1 will not be disassembled due to abrasion and the bottom portion 22a, which is a thin portion, will not be worn out.

Further, as shown in FIG. 6, the bird damage preventive tool 1 includes a plurality of bird damage preventive tools 1, 1 arranged side by side, and the protrusion 24 of one bird damage preventive tool 1 is adjacent to the other bird. If birds are stopped on the roof or the like by connecting them one after another so as to engage with the engagement holes 23 of the damage prevention tool 1 and laying them on the roof or the like.

The bird damage prevention tool according to the present invention is not limited to the above-mentioned embodiments. For example, in the above-mentioned embodiment, the projection is press-fitted into the engaging hole to hold the synthetic resin plate in the tubular shape, but it may be held in the tubular shape via bolts and nuts. . In addition, although the through holes are provided in the synthetic resin plate in the above-mentioned embodiments, the through holes may be omitted.

Further, in the above embodiment, the synthetic resin plate 2 is used.
Although the two protrusions are provided on one side in the width direction and the engaging holes are provided on the other side, the protrusions and the corresponding engaging holes may be alternately provided on both sides.
