Japanese Patent Application Laid-Open No. 61-239832

  However, since birds such as crows drop nest materials such as twigs which are materials of nests from the upper side when forming nests, the conventional multiple rows of needles for preventing birds are provided. There is a problem in that the nest material is caught by the needle and nests.

  Then, an object of the present invention is to provide a bird nesting prevention tool capable of surely preventing nesting while preventing the bird being placed.

In the bird nesting prevention device of the present invention, a plurality of upwardly projecting needles and an elongated proximal connecting portion for connecting the proximal ends of the plurality of needles are integrally formed of an insulating resin. The avian nest prevention tool, wherein the plurality of needles are arranged in only one row along the longitudinal direction of the proximal connection portion.
Moreover, it has an intermediate | middle connection collar part which mutually connects the upper-and-lower-intermediate part of the said adjacent needle | hook.
Further, the plurality of intermediate connection collars are disposed in a zigzag form in a side view.
Moreover, the said intermediate | middle connection collar part is cross-sectional circular shape, Comprising: The diameter dimension is set to 2 mm or more and 4 mm or less.
Moreover, the height dimension from the installation back surface of the proximal end connecting portion to the tip of the needle is set to 170 mm or more and 230 mm or less, and the vertical dimension from the tip of the needle to the intermediate connecting collar portion is 80 mm or more and 150 mm or less It is set to.

  According to the present invention, when a bird such as a crow makes a nest, it is possible to prevent the nest material from being caught on the needle even if a rod-like nest material such as a twig is dropped from above (dropped). That is, it is possible to reliably prevent nesting while preventing birds from being parked by the needles.

It is a perspective view which shows one form of embodiment of the bird nesting prevention tool which concerns on this invention. It is an expansion perspective view. It is a side view. It is a front view. It is a top view. It is a bottom view.

Hereinafter, the present invention will be described in detail based on the illustrated embodiments.
The bird nesting prevention tool according to the present invention is, as shown in FIGS. 1 to 5, an elongated proximal connecting portion connecting the proximal ends of the plurality of needles 1 projecting upward and the plurality of needles 1. And 2 are integrally molded of an insulating resin.

  A plurality of needles 1 are arranged in one row along the longitudinal direction (front-rear direction) N of the proximal end connecting portion 2. The plurality of needles 1 are disposed at the same position in the width direction (the same position in the left-right direction), and as shown in FIG. That is, a plurality of needles 1 are arranged in a row on a straight line in plan view.

  Furthermore, it has the middle connecting collar part 3 which mutually connects the upper-and-lower middle part of the adjacent needle | hook 1 and 1 mutually. One intermediate connecting rod portion 3 is provided between the needle 1 and the needle 1 so as to connect the adjacent needles 1, 1 in the longitudinal direction N. A plurality of intermediate connection collars 3 are provided along the longitudinal direction N as a whole. The intermediate connection collar portion 3 is provided in a shape orthogonal to the needle axial center of the needle 1 (in a horizontal shape when the installation surface G is horizontal) in a side view.

  When a bird such as a crow makes a nest, when the rod-like nest material such as a twig that is a material of the nest is dropped (dropped) from above, the intermediate connection ridge portion 3 is provided with a nest material that is falling Before reaching the surface G and the proximal end connection portion 2, contact (first) causes the nest material to slide left and right outwards (repelled) to deposit on the installation surface G and the proximal end connection portion 2 To prevent

Furthermore, when snow falls between the adjacent needle 1 and needle 1, the intermediate connecting ridge portion 3 forms a snow mass separated in the left-right direction (width direction) W and slides outward in the left-right direction. It's easy to do. Also, between the needle 1 and the needle 1, the lump of snow once deposited is divided in the left-right direction W by the intermediate connecting rod 3, and it is easy to slide off. Thus, the presence of the intermediate connecting ridge 3 can prevent the snow mass from becoming large.
In addition, since the needle row is one row, the needle 1 does not disturb the falling of the snow (does not help the growth of snow) as compared with the case where the needle row is provided in a plurality of rows.

The intermediate connection collar portion 3 is circular in cross section, and the diameter d (see FIG. 3) is set to 2 mm or more and 4 mm or less.
If it is less than 2 mm, the action of separation and division (described above) in the lateral direction W of snow can not be obtained. Furthermore, resin molding becomes difficult, and there is a possibility that the product may be deformed or damaged during product transportation or construction. If it exceeds 4 mm, birds may be easily grasped by the legs and may be parked.

  And a plurality of middle connection collar parts 3 are arranged in the upper and lower zigzag form in side view. The upper and lower positions of one intermediate connection collar 3 (3A) adjacent to each other in the longitudinal direction N and the upper and lower positions of the other intermediate connection collar 3 (3B) are made different. Even if one leg of the bird grabs one of the middle connecting ridges 3 (3A) and the other leg of the bird tries to grab the other middle connecting ridge 3 (3B), the height (upper and lower position) is Differently, because the attitude becomes unstable, the birds instinctively hated and prevent the birds.

  In addition, as shown in FIG. 3, the upper and lower step dimension Δh from one intermediate connection flange 3A (upper edge 3a) to the other intermediate connection flange 3B (upper edge 3a) is set to 15 mm or more and 30 mm or less It is desirable to do. If it is less than 15 mm, the possibility of being parked is increased. If it exceeds 30 mm, one (upper position) of the intermediate connection collar 3A approaches the tip 11 of the needle 1 too much, and the effect of the needle 1 for preventing a bird's nest becomes weak. Alternatively, before the other (lower position) intermediate connection ridge portion 3B approaches the installation surface G too much and the falling nest material abuts the lower position intermediate connection ridge portion 3B on the installation surface G There is a possibility that the nest material may be caught in an inclined manner by the installation surface G and the intermediate connection collar portion 3B at the lower position to be left.

  Furthermore, the height dimension H from the installation back surface 2b of the proximal end connection part 2 to the tip 11 of the needle 1 is set to 170 mm or more and 230 mm or less, and the intermediate connection collar 3 (upper edge 3a) from the tip 11 of the needle 1 The upper and lower dimensions h are set to 80 mm or more and 150 mm or less.

When the height dimension H is less than 170 mm, the threat (repelling) effect on birds is weakened. If it exceeds 230 mm, the handling of production, transportation and construction becomes difficult, and the usability becomes worse.
In addition, when the vertical dimension h is less than 80 mm, the tip end 11 of the needle 1 is less likely to come into contact with the birds trying to grip the intermediate connection collar portion 3, and the fowling prevention effect is weakened. Moreover, when it exceeds 150 mm, the nest material coming close to the installation surface G and falling comes in contact with the installation surface G before contacting the intermediate connection collar portion 3 and the nest material with the installation surface G There is a possibility that it may be caught in an inclined manner and remain by the intermediate connection collar portion 3 (the risk of nest material deposition is increased).

Moreover, the space | interval dimension K between the needle | hook 1 which adjoins the longitudinal direction N and the needle | hook 1 is set to 20 mm or more and 40 mm or less.
When the diameter is less than 20 mm, the needles 1 come close to each other to reduce the intimidation effect and increase the possibility of the nest material being caught. If it exceeds 40 mm, the distance between the needles 1 will be too large, and birds (heads) can easily enter between the needles 1 and the needles 1 and there is a high possibility of being parked.

The needle 1 is formed in a tapered shape in which the diameter gradually decreases from the base end (lower part) to the tip (upper part) 11, and the top is formed in a round mountain shape.
Further, in the tapered needle 1, a plurality of groove portions 12 along the vertical direction are formed in predetermined upper and lower regions (portions) from the base end portion to the predetermined position in the upper and lower middle. The four groove portions 12 are disposed at equal intervals around the needle shaft center in plan view (see FIG. 5). That is, the needle 1 forms the cross-sectional shape of the upper and lower predetermined area in a cross shape. Moreover, the upper area of the upper position above the upper and lower predetermined area has a circular cross section.

Further, the proximal end connection portion 2 is a portion to be fixed to a surface (a bird's nest nest preventing surface) G for which a bird or nest should be prevented in a power facility (a power transmission facility) such as a utility pole or a steel tower. Well, it's a fish bone type.
As shown in FIG. 1 to FIG. 6, the proximal end connection part 2 is a linear (one) vertical collar 21 connecting the proximal ends of a plurality of needles 1 and a width direction from the vertical collar 21. It is disposed between the lateral leg collar 22 which protrudes outward (right and left outward) and the lateral leg collar 22 adjacent to the longitudinal direction N, and protrudes outward from the vertical collar 21 respectively to the left and right. And a block-shaped reinforcing leg 23 having a rectangular shape in plan view.

  The pair of left and right lateral leg hooks 22, 22 correspond (coincide) with the position of the needle 1 in the longitudinal direction N so as to correspond to each of the plurality of needles 1, and the needle 1 falls sideways due to a gust or the like. To prevent. In addition, since there is no (excluded) horizontal leg tip connecting portion for connecting the distal end portions of the horizontal leg collar portions 22 adjacent to each other in the longitudinal direction N, the installation surface (a bird nesting prevention surface) Even if the width dimension of G is small and the tip of the lateral leg collar portion 22 protrudes from the installation surface G, there is no risk of being parked.

  The pair of left and right reinforcing legs 23 correspond to (coincide with) the position of the longitudinal direction N between the needle 1 and the needle 1. The reinforcing leg portion 23 is provided to have a shorter widthwise dimension (right and left projecting dimension) than the lateral leg collar portion 22. Further, the longitudinal dimension (the dimension in the front-rear direction) is provided larger than that of the lateral leg collar portion 22 to form a flat shape, and the contact area with the bird-preventing surface is increased to prevent falling and positional deviation.

  The means for fixing (fixing) the proximal end connecting portion 2 to the installation surface G such as the upper surface of the utility pole or the arm metal of the steel tower is the lower end of the proximal end connecting portion 2 (the vertical rod portion 21 or the horizontal leg portion 22). Fixing by screwing through metal fittings (fittings) to be held in a cinch form, fixing by U-shaped clamp fitting (fittings), adhesive tape, adhesive, resin binding band (fittings) It is free to fix by etc.

In addition, the proximal end connection portion 2 has a pair of front and rear horizontal column portions 25d, 25d protruding leftward and rightward at a position above the horizontal leg heel portion 22 in the longitudinal middle portion (average stands are arranged in front and rear) And a gripped portion 25 of such a shape (see FIGS. 1, 4 and 5).
The to-be-held part 25 is a site | part held by high-place installation work tools, such as a remote stick (long-handed work tool of a pin end shape) which has a wedge-like clamping mechanism, when installing in electric equipment. .
The intermediate connection collar portion 3 can prevent the entire shape from being bent in an arc mountain shape when the gripped portion 25 is gripped by a remote installation tool such as a remote stick. In other words, the intermediate connection collar 3 can prevent the needle 1 and the needle 1 from being deformed open, and the shape and posture are stabilized, and installation at a high place using a remote installation tool such as a remote stick is possible. It becomes easy.

In the present invention, the design can be changed, and a plurality of intermediate connection collars 3 may be provided in a ladder shape (ladder shape) between the adjacent needles 1 and the needles 1.
The plurality of intermediate connection flanges 3 disposed along the longitudinal direction N may be disposed at substantially the same upper and lower positions (on a straight line) in a side view. The material of the needle 1 and the proximal connection portion (base portion) 2 is an insulating material, and for example, polypropylene is desirable. In the illustrated example, the height dimensions H of the plurality of needles 1 are all the same, but the height dimensions H of the respective needles 1 may be different.

  As mentioned above, the bird nesting prevention tool of the present invention insulates a plurality of upward projecting needles 1 and an elongated proximal connecting part 2 connecting the proximal ends of the plurality of needles 1. Or the like, since the plurality of needles 1 are arranged in a single row along the longitudinal direction N of the proximal end connecting portion 2, When birds form a nest, even if a rod-shaped nest material such as a twig is dropped from above (dropped), the nest material is less likely to be caught by the needle 1, and nesting can be reliably prevented. In other words, nesting can be reliably prevented while preventing birds from being parked by the needle 1. It is possible to surely prevent the birds from being parked by eliminating the space for the birds to be parked. Moreover, compared with the case where a plurality of needle rows are provided, the needle 1 does not help upsizing (growth) of the snow. In other words, it is most suitable for preventing bird nesting in cold regions (heavy snow areas).

  Moreover, since it has the intermediate connection collar part 3 which mutually connects the upper-and-lower-intermediate part of the said adjacent needle | hook 1 and 1, the nest material which falls is an installation surface (a bird nesting prevention surface) G or a proximal end connection part Before reaching 2, the nest material slips outward to the left and right, or the nest material is repelled to contact the intermediate connection butt 3 and deposits on the installation surface G and the proximal end connection part 2 Can be prevented. In addition, it is possible to prevent the snow mass from becoming large (it is possible to prevent the growth of snow).

  Further, since the plurality of intermediate connection collars 3 are arranged in a zigzag form in a side view, one leg of the bird grips one intermediate connection collar 3A, and the other leg of the bird is: Even when trying to grasp the other middle joint ridge 3B, the height (upper and lower position) is different, and the posture becomes unstable, so the birds instinctively hated and can prevent the birds from entering the middle trunk 3 .

  Moreover, since the said intermediate connection collar part 3 is a cross-sectional circular shape and diameter diameter d was set to 2 mm or more and 4 mm or less, while being hard to grasp the intermediate connection collar part 3, birds can be prevented from being placed. Sufficient strength can be obtained to prevent deformation or breakage during product transportation or construction. In addition, it is easy to manufacture a resin mold.

  In addition, the height dimension H from the installation back surface 2b of the proximal end connecting portion 2 to the tip 11 of the needle 1 is set to 170 mm or more and 230 mm or less, and from the tip 11 of the needle 1 to the intermediate connecting collar 3 Since the upper and lower dimension h is set to 80 mm or more and 150 mm or less, it is possible to prevent the bird from being parked on the intermediate connection collar portion 3 while maintaining the threat (repelling) effect on the birds by the needle 1. In addition, the needle 1 is not too long, and its manufacture and handling are easy and convenient. The tip end 11 of the needle 1 is brought into contact with the abdomen of the bird which is trying to grasp the intermediate connection butt portion 3, and the fowling prevention effect can be improved. In addition, the nest material can be prevented from being caught on the installation surface G and the intermediate connection collar portion 3.
