Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
As shown in FIG. 1 to FIG. 3, the bird flying prevention device according to the present invention includes a plurality of resin long needles 1 and a plurality of resin short hands 2, which are mixed to form a resin band plate. It protrudes from the front surface 3a of the mounting board portion 3 in the shape of a ring.
In other words, a long needle 1 for preventing large birds such as crows and pigeons and a short needle 2 for preventing small birds such as sparrows and swallows are provided on the substrate portion 3 in a mixed manner.

  The long needle 1 and the short hand 2 are formed in a conical shape, and the tip portion has a round mountain shape. The substrate portion 3, the long needle 1 and the short needle 2 are integrally formed of resin.

Long hands 1 and short hands 2 are alternately arranged in the longitudinal direction (longitudinal direction) N of the substrate portion 3. It can also be said that a short hand 2 for preventing small birds is provided between the long hand 1 for preventing large birds and the long hand 1.
Further, the long hands 1 and the short hands 2 are alternately arranged in the lateral direction (width direction) W of the substrate portion 3.

  Four rows of needle rows each composed of the long needles 1 and the short hands 2 arranged at a predetermined pitch in the longitudinal direction N of the substrate unit 3 are provided. The long needle 1 and the short hand 2 of the two rows of needles that are arranged near the center in the lateral direction protrude vertically. The long needle 1 and the short hand 2 of the needle row provided in a row on the both side outer end portions 3d and 3d in the lateral direction W of the substrate portion 3 are inclined outwardly (projected obliquely upward). . Inclined long needles 1 and short hands 2 are provided at both outer ends in the lateral direction W of the substrate portion 3.

  Here, when the long needle 1 and the short needle 2 are collectively referred to as a threatening needle 7, the inclined threatening needles 7 projecting outwardly from both sides at the vertical side edges along the vertical direction N of the substrate portion 3 are arranged in a row. In the remaining two rows, it can be said that the threatening needles 7 are provided in a vertically projecting manner.

As shown in FIG. 2, the long hand 1 has a length dimension (protrusion dimension from the surface 3a of the substrate portion 3) S1 set to 120 mm or more and 180 mm or less.
If it is less than 120 mm, before the trunk or blade of a large bird such as a pigeon or crow comes into contact with the long needle 1, the leg of the bird can land on the substrate portion 3 and there is a possibility that it will be parked. In addition, a sufficient threat to large birds cannot be obtained. If it exceeds 180 mm, molding with a resin mold becomes difficult (the manufacturing cost increases).

The short hand 2 has a length dimension (protrusion dimension from the surface 3a of the substrate portion 3) S2 set to 30 mm or more and 80 mm or less.
If it is less than 30 mm, the leg of the bird can land on the substrate 3 before the short needle 2 comes into contact with the trunk or blade of a small bird such as a sparrow or a swallow, and there is a possibility that the bird will be parked.
If it exceeds 80 mm, it will approach the long hand 1 and, as a whole, a group of threatening needles 7 of the same size will protrude and the threatening effect will be weakened.

Further, the inclined long needle 1 and the short hand 2 have an inclination angle θ between the needle axis L and the reference horizontal plane J (the surface 3a of the substrate portion 3) set to 62 degrees or more and 75 degrees or less.
If it exceeds 75 degrees, the threatening effect on birds flying in comparison with the case of projecting vertically is not significantly changed, and if it is less than 62 degrees, the long hand 1 and the short hand 2 are too tilted, There is little threatening effect, and small birds may park on the inclined threatening needle 7. In addition, mold forming becomes difficult.

The needle lateral gap dimension Ea between the long needle 1 and the short needle 2 adjacent in the lateral direction W is set to 13 mm or more and 19 mm or less at a predetermined first reference height dimension Ha from the surface 3a of the substrate portion 3. Yes.
When the length is less than 13 mm, the needles are too close to each other to be difficult to manufacture, and the long needle 1 and the short needle 2 are densely packed, the sharpness is not emphasized, and the threatening effect is reduced. If it exceeds 19 mm, the distance becomes wide and small birds may enter.
In addition, the first reference height dimension Ha is preferably a height corresponding to the leg or trunk of a small bird when it is assumed that a small bird has landed on the substrate unit 3, for example, 18 mm or more and 30 mm or less. It is desirable to do.

Further, as shown in FIG. 3, the needle vertical gap dimension Eb of the long needle 1 and the short needle 2 adjacent to each other in the vertical direction N is set to 13 mm at a predetermined second reference height dimension Hb from the surface 3a of the substrate portion 3. It is set to 19 mm or less.
When the length is less than 13 mm, the needles are too close to each other to be difficult to manufacture, and the long needle 1 and the short needle 2 are densely packed, the sharpness is not emphasized, and the threatening effect is reduced. If it exceeds 19 mm, the distance becomes wide and small birds may enter.
Further, the second reference height dimension Hb is preferably set to a height corresponding to a leg or trunk of a small bird when it is assumed that a small bird has landed on the substrate unit 3, for example, 18 mm or more and 30 mm or less. It is desirable to do.

As shown in FIGS. 1 to 3, separation folds 31 are formed in the substrate portion 3 in the vertical direction N and the horizontal direction W.

In other words, the longitudinal fold groove 31a is formed at a central position between one needle row composed of the vertical long needle 1 and the short needle 2 and the other needle row composed of the vertical long needle 1 and the short needle 2. .
The lateral folding grooves 31 b are formed at the center position between the long hands 1 and the short hands 2 adjacent to each other in the vertical direction N, and a plurality of the horizontal folding grooves 31 b are provided on the substrate portion 3.

As shown in FIG. 4, the lateral folding groove 31 b is for dividing the substrate portion 3 into a plurality of portions in the vertical direction N. That is, when the long needle 1, the short needle 2 and the substrate portion 3 as shown in FIGS. 1 to 3 are integrally formed of resin, the preventive tool body 8 is referred to as a vertical dimension. It can be adjusted in correspondence. In other words, the prevention tool main body 8 can be divided into a plurality of small prevention tools 80 each having a strip-like divided substrate piece 81 whose longitudinal dimension is shorter than that of the belt-like substrate portion 3.

That is, it is possible to obtain a plurality of elongated small preventers 80 having a vertical dimension and a horizontal dimension smaller than those of the preventer body 8.

  Although not shown in the drawing, the vertical folding groove 31a and the horizontal folding groove 31b are divided into the smallest divided substrate piece 81 obtained by dividing (the substrate part 3 is divided into the smallest parts), one long needle 1 and one short needle 2. It is provided to project. Further, on the smallest divided substrate piece 81, one of the long hand 1 and the short hand 2 protrudes vertically and the other protrudes inclined.

As shown in FIG. 7, an adhesive is applied to the back surface 3b of the substrate portion 3 and a concave groove 38 for the adhesive is provided along the vertical direction N for guiding the discharge nozzle of the adhesive container. A plurality (three in the figure) are provided.
The tip of the discharge nozzle is made to correspond to the concave groove 38, and the adhesive can be discharged while sliding the discharge nozzle along the concave groove 38, so that the adhesive application work can be performed easily and appropriately. It becomes possible.

  The three concave grooves 38 are arranged in the lateral direction W, one at the same position in the horizontal direction as the vertical fold groove 31a (the center position in the horizontal direction) and one on each side in the horizontal direction around the vertical fold groove 31a. Provided. By providing in this way, when the substrate part 3 is divided by the longitudinal folding groove 31a, one groove 38 is left in the strip-like divided substrate piece 81, and is bonded to the elongated small preventer 80. The agent can be easily applied.

In addition, the substrate portion 3 is notched inward in the lateral direction between the long needle 1 and the short hand 2 adjacent to each other in the longitudinal direction N from both outer ends (both longitudinal side edges along the longitudinal direction N of the substrate portion 3). A notch-shaped relief part 36 (which was recessed inward inward) was formed.
Although not shown, the escape portion 36 and the through hole 37 may be communicated with each other.

  As shown in FIG. 8, one preventer main body 8A and the other preventer main body 8B are arranged in the vertical direction so that the horizontal center lines coincide with each other. A stack in which one preventive tool body 8A and the other preventive tool body 8B are shifted in the vertical direction N so that the vertical threatening needles 7B of the lower protector body 8B correspond to the holes 37A. Prepared.

  From the stacking preparation state, when one preventive tool main body 8A and the other preventive tool main body 8B are relatively approached in the vertical direction, as shown in FIG. 8 to FIG. 9, the lower vertical threatening needle 7B is While passing through the upper through-hole 37A, the lower inclined threatening needle 7B corresponds to the upper relief part 36A, and contact (interference) between the upper board part 3A and the lower threatening needle 7B is prevented. The That is, it can be stacked up and down until the rear surface 3b of the upper substrate portion 3A contacts the surface 3a of the lower substrate portion 3B. As shown in FIG. 9, the upper threatening needles 7 </ b> A and the lower threatening needles 7 </ b> B are alternately arranged in the vertical direction N in the stacked state. It is not bulky and can be easily stored, packed, and transported.

Further, as shown in FIGS. 2 and 3, the thickness t (excluding the folding groove 31 and the concave groove 38) of the substrate portion 3 is preferably a thin plate shape of 1.5 mm or more and 5 mm or less. If it is less than 1.5 mm, the strength becomes weak. If it exceeds 5 mm, the folding groove 31 needs to be formed deeply, and the strength becomes excessive, and the material is wasted.
Further, it is desirable that the preventer main body 8 (the long needle 1, the short needle 2, and the substrate portion 3) is made of polycarbonate or ABS. Alternatively, PP (polypropylene) or PE (polyethylene) may be used.

The operation (use method) of the bird flying prevention tool of the present invention will be described.
Adhesive is applied to the concave groove 38 on the back surface 3b of the substrate portion 3, and as shown in FIGS. 10 and 11, the covering portion of the attached portion (bird guarding portion) K such as a block rail or a handrail of a veranda is provided. It adheres (adheres) to the attachment surface (upper surface) Ka.

The prevention tool main body 8 to which the adhesive is applied can be easily held. Further, a finger is put between the long needle 1 and the long hand 1 so that the surface 3a of the substrate portion 3 can be easily pressed, and the back surface 3b of the substrate portion 3 is brought into close contact with the upper surface Ka of the attachment portion K with a strong pressing force. It can be made to adhere.

  After the prevention device main body 8 is installed, the size of the long hand 1 is emphasized by the step between the long hand 1 and the short hand 2, and the threatening effect on large birds can be improved. In addition, the step between the long hand 1 and the short hand 2 emphasizes the sharpness of the long hand 1 and the short hand 2 and produces a zigzag shape like a saw, (compared to a case where needles of the same size are simply projected). ) Improving the threat and repelling effect on birds, can surely prevent flying (parking of birds).

  In addition, small birds approach to try to park between the long needle 1 and the long needle 1 that are easy to hide from external enemies such as crows and cats. It feels a threat to the people, provides threats and avoidance effects, and prevents flying. In addition, the short needle 2 eliminates the space for holding small birds between the long hand 1 and the long hand 1.

  Here, as an example of how to attach the bird flying prevention tool (bird flying prevention structure), the side outer end portion 3d of the board portion 3 is placed on the upper edge Kd of the attachment portion K where there is a high possibility that birds will approach. Correspondingly, the substrate portion 3 is bonded to the attachment surface Ka so that the outer edge of the substrate portion 3 does not protrude outward from the upper edge Kd. Preferably, the upper side edges Kd and Kd of the attachment portion K are bonded so as not to protrude outward from the both side outer ends of the substrate portion 3. By providing in this way, a plane or space where small birds can park is not formed between the inclined long needle 1 and the short needle 2 and between the attachment surface Ka, and the flying of small birds can be prevented. .

  Furthermore, as shown in FIG. 12, when the attachment portion K is a narrow stepped portion such as the vicinity of a window of a building or a beam, as shown in FIG. 5 or FIG. The substrate part 3 is divided in the lateral direction W by the longitudinal folding grooves 31a, and the lateral dimension of the substrate part 3 is adjusted. Further, the vertical dimension is set by the lateral folding groove 31b. In other words, the prevention device main body 8 is divided into the elongated small preventive device 80 having the strip-like divided substrate pieces 81, and the elongated small preventive device 80 is bonded to the attachment surface Ka.

  The elongated small preventive device 80 is composed of a long needle 1 and a short needle 2 protruding in an inclined manner, with a vertical needle row composed of a long needle 1 and a short needle 2 projecting vertically as a vertical surface F side such as a wall surface or a window. The inclined needle row (the outer outer side of the substrate portion 3) is bonded (fixed) in correspondence with the upper edge Kd where there is a high possibility that birds will approach. In this way, the size of the prevention tool main body 8 can be adjusted flexibly at the construction site by hand without using a cutting tool by means of the folding groove 31, and it can be constructed according to various attachment parts K (birds) (Flying prevention work) can be performed.

Formed in the shape of a window (through hole), the outer ends on both sides of the substrate part 3 are connected along the vertical direction N in the form of connecting rods (both vertical side edges along the vertical direction N of the substrate unit 3 are formed in a narrow rod shape ) Remains. Other configurations and operations are the same as those in the above-described embodiment.
By providing in this way, when separating the substrate part 3 in the fold groove 31, it is easy for an operator to grip, and the force of fingers is easily transmitted, so that the separation work can be performed easily and smoothly. Can do. In FIG. 14, the groove 38 is not shown.

The present invention can be modified in design, and four or more needle rows may be provided. A plurality of vertical folding grooves 31a may be provided. For example, it may be provided between a needle row projecting vertically and a needle row projecting inclined. The long needle 1 and the short hand 2 are not limited to a conical shape, and may be a quadrangular pyramid shape or a polygonal pyramid shape (the cross-sectional shape of the long needle 1 and the short hand 2 is not limited to a circle, but may be a rectangular shape or a polygonal shape). .
In addition, the direction is described with the posture in which the surface 3a of the substrate unit 3 is directed upward being the reference posture. Therefore, the posture in use is not limited based on the direction. For example, it is possible to use the substrate unit 3 bonded to a vertical surface such as a wall surface. Alternatively, a double-sided adhesive tape may be adhered to the back surface 3 b of the substrate unit 3 and fixed to the attachment portion K. Moreover, the board | substrate part 3 may form both the vertical side edge parts (both outer edge part 3d, 3d of the board | substrate part 3) in uneven | corrugated shape or a wave shape in planar view along the vertical direction N. FIG. In other words, a double-edged saw plate may be used in plan view.

  As described above, the bird flying prevention tool of the present invention projects a plurality of resin long needles 1 and a plurality of resin short needles 2 in a projecting manner from the resin mounting substrate portion 3. Not only large birds such as crows and pigeons but also small birds such as sparrows and swallows do not fly, and fecal damage can be reliably prevented. The resin can be integrally formed and can be easily manufactured. Lightweight and easy to handle, construction work can be performed safely and smoothly.

  Further, since the long hands 1 and the short hands 2 are alternately arranged in the longitudinal direction N of the substrate portion 3 and the long hands 1 and the short hands 2 are alternately arranged in the lateral direction W, the irregularities of the long hands 1 and the short hands 2 are arranged. Can increase the threat and repellent effect on birds and prevent the arrival of birds of various sizes.

  Further, since the separation folding grooves 31 are formed in the vertical direction N and the horizontal direction W in the substrate portion 3, separation can be performed easily and quickly by hand without using a cutting tool such as a nipper or a cutter. The horizontal dimension and the vertical dimension can be easily adjusted at the construction site so as to correspond to various attachment parts K.

  In addition, since the length dimension S1 of the long hand 1 is set to 120 mm or more and 180 mm or less and the length dimension S2 of the short hand 2 is set to 30 mm or more and 80 mm or less, the sharpness of the long needle 1 and the short needle 2 is obtained, and the needle tip Can be enhanced, and threatening and avoidance effects can be improved.
