Description

  The present invention relates to a bird damage prevention tool that is attached to an outdoor structure and prevents bird damage caused by birds.

  Birds may stop in outdoor structures such as utility pole braces, or nest and cause bird damage. The brace is used to support the distribution line on the upper part of the utility pole, and the distribution line is supported by the brace via a lever. The brace has various shapes and sizes depending on the application, and may have a flat upper surface. This flat top is suitable for birds to nest and rest. As specific bird damage, there are cases where wires scattered on the ground are collected to form a nest on the armor, or manure discharged from birds nesting or resting on the armor is dropped on the ground.

In order to cope with such bird damage, techniques related to prevention of bird damage have been proposed. For example, Patent Document 1 discloses a bird damage prevention device in which birds such as the upper surface of a brace are fixed at a place where nesting and resting are easy and a plurality of rods having a predetermined shape are bundled. This bird damage prevention tool includes a plurality of rods each shaped in an inverted U-shape as a whole, and a mounting bracket for bundling one end of the plurality of rods so as to expand in a fountain shape and fixing them to a brace. including.
Japanese Utility Model Publication No. 63-31589

  The conventional bird damage prevention device can block a space where birds on the upper surface of the arm metal can nest and rest with a plurality of rods developed in a fountain shape. This makes it difficult for birds to stop on the upper surface of the brace and prevents bird nesting and resting. Further, since this bird harm prevention tool is formed by bundling a plurality of rods shaped into a predetermined shape, the amount of material used is small, and formation (shaping) is easy.

  However, even if the bird damage prevention device can prevent bird nesting and resting on the upper surface of the brace, it is difficult to prevent birds from stopping on the bird damage prevention device itself. That is, each rod has a substantially inverted U shape, and the curved portion in the middle in the length direction extends in a direction close to the horizontal direction. Birds tend to stop at the curved portion close to the horizontal direction, and feces and urine discharged by the birds stopped near the horizontal direction due to rest may fall on the ground.

  The present invention has been made in view of the above-mentioned problems, and while enjoying the advantages of the above conventional bird damage prevention device, it can solve the problems and prevent bird nesting and resting in outdoor structures, and also resting etc. Therefore, an object of the present invention is to provide a bird damage prevention tool that can prevent birds from stopping on the bird damage prevention tool itself.

The bird damage prevention device according to the present invention is a bird damage prevention device attached to an outdoor structure as described in claim 1, wherein the plurality of linear members and the plurality of linear members are bundled together. A fixture that is fixed to an outdoor structure, and each linear member includes a first straight portion that is bundled with the fixture, an elastic portion having one end connected to the first straight portion, and the elastic portion. A second linear portion connected to an end, and the elastic portion is arranged such that each second linear portion is positioned above the first linear portion, and the second linear portions are each It has the elasticity which bends in a dogleg shape with respect to a 1st linear part.

According to the bird damage prevention device of the present invention, since the elastic portion is formed in the middle of the plurality of linear members, the elastic portion is displaced when the birds try to stop on the other end side of the elastic portion . As a result, it is difficult for birds to stop on the other end side of the elastic part which is easily displaced, and feces caused by the birds stopping on the bird damage prevention tool itself can be prevented. In addition, a plurality of linear members occlude the upper surface and the upper space of outdoor structures to expand like a fountain by having an elastic portion, birds or close to the outdoor structures, it is difficult to stop on its upper surface Therefore, nesting on the upper surface of the outdoor structure can be prevented.

Then, the elastic portion Ru can use coil springs for example (claim 2 see). Thereby, the desired elasticity which makes it easy to displace the 2nd straight part can be obtained simply and reliably by the coil spring. Moreover, you prevent even it if coil elastically deformed and weight of birds, stops the elastic portion.

In addition to the plurality of linear members, one end of the linear member may be attached to the fixture, and may include at least one linear linear member that extends upward (hereinafter, referred to as “linear linear member” as appropriate) ( ( See claim 3 ). Accordingly, the birds are disturbed by the linear linear member and are difficult to approach the linear member from above, and it is possible to prevent the birds from stopping on the bird harm prevention tool from above.

Moreover, the wind receiving part which receives a wind and displaces a 2nd linear part can be formed in the free end of the 2nd linear part of a shaping linear member (refer Claim 4 ). As a result, the area receiving the wind increases, so even if the birds do not contact the first straight portion or the like, the second straight portion is easily displaced even when a breeze is blown, and the elastic portion is elastically deformed. 2 It becomes difficult for birds to stop at the straight part and the elastic part .
