  As shown in FIG. 1, the bird damage prevention tool 1 has a base 100 provided in a substantially lattice shape as a skeleton. The bird damage prevention device 1 includes a needle-like body 200 on the base body 100 that cannot be grasped even when birds such as pigeons and crows try to land. The bird harm prevention tool 1 is connected to another bird harm prevention tool 1 (hereinafter referred to as “bird harm prevention tool 1 ′”) in order to arrange a plurality of the bird harm prevention tools 1 in a bird harm occurrence place. 300. The bird damage prevention device 1 including the base body 100, the needle-like body 200, and the coupling body 300 is integrally formed of a known resin material having weather resistance, such as polypropylene, and is formed to be elastically deformable. It is formed so that it can be easily cut at the installation work site.

  The base body 100 includes a plurality of support portions 110 that extend in parallel and a plurality of connection portions 120 that connect adjacent support portions 110 among the plurality of support portions 110. In the present embodiment, the direction in which the support portion 110 extends (X direction in the drawing) and the direction in which the connection portion 120 extends (Y direction in the drawing) are respectively referred to as “extension direction of the support portion 110” and “connection portion”. 120 extension directions ”. The direction in which the needle-like body 200 projecting from the base body 100 extends (the Z direction in the figure) is referred to as the “projection direction of the needle-like body 200”. Moreover, in this embodiment, the direction of the ground contact surface side of the bird damage prevention device 1 when the bird damage prevention device 1 is installed at the bird damage occurrence location is defined as the downward direction, and the direction opposite to this is defined as the upward direction. The upper side is the side where the needle-shaped body 200 of the bird harm prevention tool 1 is present.

  The support part 110 has a shape in which the cross-sectional shape is extended into a rod shape with a substantially semicircular shape. And the support part 110 forms the bottom face of the support part 110, and the bottom face part 111 used as the grounding surface when installing the bird damage prevention tool 1 in a bird damage occurrence place (refer FIG. 4, FIG. 5), bottom face part An upper surface portion 112 that faces the upper surface 111 and has a substantially curved surface shape that protrudes upward and forms the upper surface of the support portion 110 (see FIGS. 3 and 5).

The thickness of the support part 110 and the dimension of the extension length Lx are not particularly limited, and can be appropriately designed in consideration of the characteristics of the place where bird damage occurs, the type of birds, cost, workability, and the like. For example, the wall thickness = about 7 mm and the extension length Lx = about 600 mm. The substrate 100, such support section 110 extends a plurality of parallel with a predetermined interval I ₁ (see FIGS. 3 and 4). In the present embodiment, as shown in the figure, two support portions 110 extend in parallel with a predetermined interval I _1. The size of the gap I ₁ between the support portion 110 also, if sufficiently larger than the thickness dimension of the needle body 200 is not particularly limited. As an example, the spacing I ₁ can be about 40 mm.

  The connecting portion 120 has a shape that is formed in a rod shape with a substantially rectangular cross-sectional shape. And the connection part 120 forms the bottom face of the connection part 120, the bottom face part 121 used as the grounding surface at the time of installing the bird damage prevention apparatus 1 in a bird damage occurrence place (refer FIG. 4, FIG. 6), and a bottom face part An upper surface portion 122 (see FIGS. 3 and 6) that forms the upper surface of the connection portion 120 is provided opposite to 121.

In the present embodiment, a plurality of connection portions 120 are arranged at a predetermined interval I ₂ along the extending direction of the support portion 110 (see FIGS. 3 and 4). The extending direction of each connecting portion 120 is substantially orthogonal to the extending direction of the support portion 110. The thickness of the connecting portion 120 is not particularly limited, and can be appropriately designed in consideration of the characteristics of the bird damage occurrence location, the type of birds, cost, workability, and the like. Further, the dimensions of the gap I ₂ of the connecting portion 120 between the adjacent well, if sufficiently larger than the thickness dimension of the needle body 200 is not particularly limited. Further, the extension length Ly of the connecting portion 120 is substantially the same as the interval I ₁ of the support portion 110. For example, the wall thickness = about 7 mm, the extension length Ly = about 40 mm, and the interval I ₂ = about 30 mm.

  A pair of projecting portions 130 projecting outward are provided on both outer side surfaces of the support portion 110 (see FIGS. 3 and 4). When there are three or more support portions 110, the two support portions 110 located on both outer sides are used as a pair of support portions 110, and a pair of protrusions 130 are provided on both outer side surfaces of the pair of support portions 110. ing. When there are two support portions 110, each support portion 110 forms a pair of support portions 110. Further, the protruding length of each of the pair of protruding portions 130 is not particularly limited, and can be appropriately designed. As an example, the protrusion length of each protrusion 130 may be approximately 12.5 mm.

  In the present embodiment, each protrusion 130 has substantially the same shape as the connection portion 120. And a pair of protrusion part 130 is provided so that each may protrude toward the outer side along the extended line of the both ends of the one connection part 120 which connects the two support parts 110. As shown in FIG. Therefore, in the present embodiment, it can be considered that both ends of the connection portion 120 extend beyond the pair of support portions 110. The pair of projecting portions 130 can be considered to be a part of one connection portion 120 that extends beyond the pair of support portions 110. That is, the connecting portion of the present invention also includes the protruding portion 130 of the present embodiment.

In addition, the base body 100 includes an opening 140 surrounded by the adjacent support portion 110 and the adjacent connection portion 120 (see FIGS. 3 and 4). A plurality of connection portions 120 are arranged at a predetermined interval I ₂ along the extending direction of the support portion 110, and the extending direction is also orthogonal to the extending direction of the support portion 110. Therefore, a plurality of substantially rectangular openings 140 are formed in the base body 100 along the extending direction of the support portion 110. The external dimensions of the opening 140 are the dimension of the interval I ₂ in the extending direction of the support part 110 and the dimension of the interval I ₁ in the extending direction of the connecting part 120.

  The opening 140 may be formed by preparing a single resin flat plate and drilling a plurality of through holes in the resin flat plate. However, as in the present embodiment, the base 100 is configured by the rod-shaped support portion 110 and the connection portion 120 to form the opening 140, so that the resin material can be made while having sufficient rigidity and flexibility. The amount used can be reduced. Therefore, the weight reduction and cost reduction of the base body 100 can be achieved.

  In addition, a concave groove 150 is provided on the bottom surface portion 111 of the support portion 110 and the bottom surface portion 121 of the connection portion 120 (see FIGS. 4, 6, and 7). In the present embodiment, one groove 150 is provided at the center of the bottom surface portion 111 of each support portion 110, and one groove 150 is provided at the center of the bottom surface portion 121 of each connection portion 120. Further, the extending direction of the groove 150 is substantially parallel to the extending direction of the support portion 110.

  In the present embodiment, since the extension length Ly of the connection part 120 is sufficiently shorter than the extension length Lx of the support part 110, the bending rigidity of the connection part 120 is larger than the bending rigidity of the support part 110. ing. For this reason, in this embodiment, by providing the groove 150 along the support portion 110, the base body 100 can be easily bent upward in the extending direction of the connecting portion 120, and the extending direction of the connecting portion 120 can be increased. The flexibility is ensured.

  Therefore, by providing the groove 150, the bird damage prevention tool 1 of the present embodiment can be easily curved upward and convex in the extending direction of the connecting portion 120. At this time, the protruding direction of the needle-shaped body 200 extends radially outward. Thereby, in the bird damage prevention tool 1 of this embodiment, even if the mounting surface of the bird damage occurrence place is a curved surface, it can be installed along the mounting surface and can sufficiently exhibit the bird damage prevention effect. it can.

  The upper surface 122 of the connecting portion 120 is provided with a curved portion 123 that protrudes upward along the shape of the groove 150 provided in the bottom surface 121 (see FIGS. 6 and 7). The curved portion 123 plays a role of reinforcing the strength of the thinned portion by providing the connecting portion 120 with the groove 150. In addition, by making the shape of the curved portion 123 convex upward along the shape of the groove 150, the base body 100 can be further easily bent upward in the extending direction of the connecting portion 120.

  Further, the flexibility in the extending direction of the support portion 110 of the base body 100 is ensured by the support portion 110 having a rod-like shape formed of an elastically deformable resin material. 100 is easily bent upward in the extending direction of the support portion 110.

  By the way, on the upper surfaces of the connection part 120 and the protrusion part 130, a plurality of needle-like bodies 200 are provided so as to protrude upward, avoiding the curved part 123. Specifically, the needle-like body 200 has only the upper surface portion 122 of the connecting portion 120 and the upper surface portion 131 of the protruding portion 130 as the base ends, and the distal end extends toward the upper side of the bird harm prevention tool 1 (FIG. 3). reference). The projecting directions of the needle-like bodies 200 are substantially perpendicular to the extending direction of the support portion 110 and the extending direction of the connecting portion 120, respectively.

  The needle-like body 200 has a substantially spire shape in which the cross-sectional shape of the base end portion is substantially hollow and the outer diameter gradually decreases upward. The tip of the needle-like body 200 is rounded to the extent that it does not damage birds. Further, the inside of the needle-like body 200 is hollow so that the amount of the resin material used can be reduced.

  The protruding length and the thickness of the needle-shaped body 200 are sufficiently longer than the length of the leg of the bird, and can secure the strength that the needle-shaped body 200 does not buckle even when the bird lands. The size is not particularly limited as long as the size is not possible. For example, the thickness of the base end portion of the needle-like body 200 may be about 7 mm, and the protruding length Lz may be about 147 mm.

  In addition, a plurality of needle-like bodies 200 are disposed on one connection part 120 that connects adjacent support parts 110 to each other so as to be spaced apart from each adjacent support part 110 (see FIG. 3). . At this time, the interval between the needle-like bodies 200 adjacent to each other in the extending direction of the one connecting portion 120 is not particularly limited as long as each interval is sufficiently narrower than the bird's trunk.

In this embodiment, the needle body 200 is assumed to be more disposed with a predetermined interval I ₃ along the extending direction of the one connecting portion 120 which includes a pair of protrusions 130 (FIG. 3, (See FIG. 6). For example, the interval I ₃ is set to about 17 mm, two are arranged on the upper surface portion 122 of one connection portion 120, and one is disposed on each upper surface portion 131 of the pair of projecting portions 130 on the extension line. It can be arranged. That is, a total of four needle-like bodies 200 can be provided on one connection part 120 including a pair of protrusions 130 with an interval I ₃ = 17 mm. The needle-like body 200 is arranged at the same interval as the interval I ₂ of the connection portion 120 in the extending direction of the support portion 110.

  In addition, the base body 100 is provided with a connecting body 300 for connecting a plurality of bird damage prevention tools 1 side by side with other bird damage prevention tools 1 ′ when the bird damage prevention tools 1 are installed in a bird damage occurrence place. In this embodiment, the connection body 300 engages with the connection portion 310 that plays the role of an engagement protrusion piece having a hook-shaped barb (see FIG. 7B), and the engagement protrusion piece of the connection portion 310. It is comprised from the to-be-connected part 320 which plays the role of an engagement protrusion hole, and (refer Fig.7 (a)).

  The dimension of the coupling body 300 is set smaller than the dimension of the interval between the needle-like bodies 200 adjacent to each other in the extending direction of the support portion 110. In addition, the size of the connecting body 300 is such that when it is connected to another bird harm prevention tool 1 ′, it is adjacent to the connecting part 310 and the connected part 320 of the other bird harm prevention tool 1 ′ and is adjacent to the needle-like body. The interval between 200 is set to be a length that can secure a distance for obtaining a bird damage prevention effect.

  Then, by engaging the connecting portion 310 with the connected portion 320 of the other bird damage prevention device 1 ′, the plurality of bird damage prevention devices 1 can be connected to each other. Moreover, the place where the connection part 310 and the to-be-connected part 320 are provided differs with respect to the one bird damage prevention tool 1 according to which direction the other bird damage prevention apparatus 1 'is connected.

  For example, in order to connect another bird harm prevention tool 1 ′ in the extending direction of the connecting portion 120, the connecting portion 310 or the connected portion 320 is directed outward from both outer side surfaces of the pair of support portions 110. Projecting. Specifically, the connecting portion 310 is provided so as to protrude outward from the outer surface of one support portion 110 of the pair of support portions 110 (corresponding to reference numeral 310a in the drawing), and the connected portion 320 is , And is provided so as to protrude outward from the outer surface of the other support portion 110 of the pair of support portions 110 (corresponding to reference numeral 320a in the figure).

  In the present embodiment, a pair of protrusions 130 are provided on the outer side surfaces of the pair of support portions 110 so as to protrude outward along the extending direction of the connection portion 120. Further, the needle-like body 200 is provided on the upper surface portion 131 of each protrusion 130. Therefore, the connection part 310 of this embodiment is provided in the front-end | tip part outside the needle-like body 200 provided in one protrusion part 130 of a pair of protrusion parts 130 along the extending direction of the connection part 120. It protrudes toward the outside. In addition, the connected portion 320 of the present embodiment is provided at the distal end portion outside the needle-like body 200 provided on the other protruding portion 130 so as to protrude outward like the connecting portion 310.

  Further, in order to connect another bird harm prevention tool 1 ′ in the extending direction of the support part 110, the connecting part 310 or the connected part 320 protrudes outward from both end surfaces of the supporting part 110 in the extending direction. Is provided. Specifically, the connecting portion 310 is provided so as to protrude outward from one of the end surfaces in the extending direction of the support portion 110 (corresponding to reference numeral 310b in the drawing), and the connected portion 320 is The support portion 110 is provided so as to project outward from the other end surface of the both end surfaces in the extending direction (corresponding to reference numeral 320b in the figure).

  In addition, the connection part 310 and the to-be-connected part 320 for connecting other bird damage prevention tools 1 'with the extension direction of the support part 110 with respect to one bird damage prevention tool 1 are the extension of the connection part 120. The connecting part 310 and the connected part 320 for connecting other bird harm prevention tools 1 ′ in the direction may be the same or different, but in the present embodiment, they are the same. For this reason, in this embodiment, the shape of the shaping | molding die of the connection part 310 and the to-be-connected part 320 can be completed with one kind, and manufacturing cost can be reduced.

  Next, the aspect of each structure at the time of stacking the above bird damage prevention tools 1 in the up-down direction is demonstrated using FIG. 8 thru | or FIG.

  Specifically, two bird damage prevention tools 1 are prepared, and the extension direction of each base body 100 and the protruding direction of the needle-like body 200 are aligned in the same direction, and one bird damage prevention tool 1 is attached to another The case where it stacks | stacks on the bird damage prevention tool 1 'from the upper side of another bird damage prevention tool 1' is demonstrated. In such a case, the ground contact surface (specifically, the bottom surface portion 111 of the support portion 110 and the bottom surface portion 121 of the connection portion 120) of the base body 100 of the bird damage prevention device 1 is a needle of another bird injury prevention device 1 ′. The tip of the body 200 ′ is approached. In FIG. 8 to FIG. 10, description will be made with “′” added to the reference numerals of the members constituting the other bird damage prevention tool 1 ′.

First, the support unit 110 is configured such that one bird damage prevention device 1 (located on the upper side in FIG. 8A) is opposite to another bird damage prevention device 1 ′ (located on the lower side in FIG. 8A). Is shifted by a distance d shorter than the interval I ₂ . Subsequently, the bird harm prevention tool 1 shifted by the distance d is moved downward toward another bird harm prevention tool 1 ′. In addition, the dashed-two dotted line of Fig.8 (a) has shown the state after stacking the bird damage prevention tool 1 on the other bird damage prevention tool 1 'in the up-down direction.

At this time, in this embodiment, in each bird harm prevention tool 1, the needle-like body 200 is provided only in the connection part 110 and the protrusion part 130, and the needle-like body 200 is not provided in the support part 110. Further, in each bird damage prevention device 1, the connection part 110 is disposed with a predetermined interval I ₂ in the extending direction of the support part 110. Further, since the protruding portion 130 is provided on the extension line of the connecting portion 120, the protruding portion 130 is arranged with a predetermined interval I ₂ in the extending direction of the support portion 110. Further, the opening 140, the length in the extending direction of the supporting portion 110 is substantially the same as the length of the interval I _2.

Further, in the present embodiment, the thickness dimension in the extending direction of the support portion 110 of needle body 200 is sufficiently smaller than the length of the interval I _2. Further, the thickness dimension in the extending direction of the connection portion 120 of the needle body 200 is sufficiently smaller than the length of the interval I _1. In addition, the needle-like body 200 is disposed apart from the adjacent support portions 110 on one connection portion 120 that connects the adjacent support portions 110 to each other. Further, the needle-like bodies 200 are disposed at an interval I ₂ in the extending direction of the support portion 110. Further, the projecting direction of the needle-like body 200 is also substantially perpendicular to the extending direction of the support part 110 and the connection part 120, respectively.

  Therefore, in this embodiment, as shown in FIG. 8, the needle-like body 200 ′ on the connection part 120 ′ of the other bird damage prevention device 1 ′ is inserted into the opening 140 of the bird damage prevention device 1. Thus, the bird damage prevention tool 1 can be moved downward. Then, as shown in FIG. 9, both the bottom surface portion 111 of the support portion 110 of the bird damage prevention tool 1 and the upper surface portion 112 ′ of the support portion 110 ′ of the other bird damage prevention device 1 ′ are brought into contact with each other. The bird damage prevention device 1 can be stacked.

  Therefore, in this embodiment, the bird damage prevention tool 1 can be easily stacked on another bird damage prevention tool 1 ′ by shifting the distance d only in one direction (the extending direction of the support portion 110). For this reason, in the bird harm prevention tool 1 of this embodiment, since it is not bulky even if the several bird damage prevention tool 1 is stacked, the packing property and workability | operativity at the time of conveyance and storage can be improved.

  Moreover, in this embodiment, the bird damage prevention tool 1 has flexibility in the extending direction of the support part 110 and the extending direction of the connection part 120, and the base body 100 is placed with the needle-shaped body 200 facing upward. It can be curved upward and convex. That is, in this embodiment, even if the mounting surface of the bird damage occurrence place is a curved surface, the bird damage prevention tool 1 can be appropriately installed by following the mounting surface.

For example, as shown in FIG. 10, the bird damage prevention device 1 can be stacked while being shifted from the other bird damage prevention device 1 ′ by a distance longer than the interval I _{2 in} the extending direction of the support portion 110. In other words, in the present embodiment, the size of the bird harm prevention tool 1 installed on the placement surface is set in accordance with the size or shape of the placement surface of the bird damage occurrence location, for example, the extending direction of the support portion 110. Can be adjusted to a longer size. In particular, when a plurality of bird damage prevention devices 1 are installed in the extending direction of the support portion 110, the length of the bird damage prevention device 1 installed on the mounting surface without cutting the bird damage prevention device 1 is set. Since it can be adjusted, the adjustment work is easy.

  Therefore, in the present embodiment, when the bird damage prevention device 1 is installed at the bird damage occurrence location, the size and shape thereof can be flexibly changed at the installation work site according to the size or shape of the placement surface of the bird damage occurrence location. Can be adjusted. For this reason, in the bird harm prevention tool 1 of this embodiment, workability | operativity at the time of installation can be improved irrespective of the condition of the mounting surface of a bird damage occurrence place.

The present invention can be modified in various ways as long as there is no particular contradiction or problem in its purpose and configuration. For example, in the present embodiment, the number of support portions 110 is two, but the present invention is not limited to this, and may be three or more. In the present embodiment, a plurality of connection portions 120 are arranged at a predetermined interval I ₂ along the extending direction of the support portion 110, but the present invention is not limited to this, and the interval I _2. May be different for each adjacent connecting portion 120.

  In the present embodiment, the extending direction of each connecting portion 120 is substantially orthogonal to the extending direction of the support portion 110. However, the present invention is not limited to this, and the extending direction of the connecting portion 120 is not limited thereto. The exit direction and the extending direction of the support 110 may not be substantially orthogonal. Further, the protruding direction of the needle-like body 200 may not be a direction substantially perpendicular to the extending direction of the support portion 110 and the extending direction of the connecting portion 120. Further, the protruding direction of the protruding portion 130 may not be along the extension line at both ends of the connecting portion 120.

Further, in the present embodiment, a plurality of needle-like bodies 200 are arranged with a predetermined interval I ₃ along the extending direction of one connecting portion 120 including a pair of protruding portions 130. The present invention is not limited to this, and the interval I ₃ may be different for each needle-like body 200. In addition, the needle-like body 200 may not be provided on the protrusion 130.

  In any case, according to the present invention, in the bird harm prevention tool 1, the needle-like body 200 is provided and supported only on the connecting portion 110 (the protruding portion 130 is optional) out of the supporting portion 110 and the connecting portion 120 constituting the base body 100. The part 110 may not be provided with the needle-like body 200. Then, the needle-like body 200 projecting on the one connection part 120 is adjacent to the one connection part 120 in the extending direction of the support part 110 (hereinafter referred to as “the opening part”). In contrast, any arrangement and shape that can be inserted may be used.

  Then, if the bird damage prevention device 1 is shifted in the extending direction of the support portion 110 by a distance shorter than the dimension of the opening portion in the extending direction of the support portion 110, the opening portion of the one bird damage prevention device 1 is used. In 140, the needle-like body 200 ′ on the connection part 120 ′ of the other bird damage prevention device 1 ′ can be inserted vertically. In other words, the bird damage prevention device 1 can be stacked up and down while being shifted from the other bird damage prevention device 1 ′ by a distance shorter than the dimension in the extending direction of the support portion 110 of the opening.
