Fixing with clamp metal fittings, fixing with adhesive tape, adhesive (material), resin binding band, etc. are free.

Next, the usage method (action) of the bird parking prevention apparatus according to the present invention will be described.
Laying on the armrests (arms) where birds such as utility poles and steel towers are parked, and the upper surfaces (installation surface G) of transformers and switches, etc., eliminate the bird parking space and prevent bird parking.

  Further, even if birds carry nesting materials such as branches and wires and drop them between the needles 11 and 11, the nesting material slides on the flexible wire 3 or the spring of the flexible wire 3 Play with action to prevent accumulation. In particular, when the flexible wire 3 is in a position above the top 10 of the needle 11, it slides more smoothly to the outer side in the longitudinal direction and the outer side in the lateral direction to prevent deposition.

Further, even if the birds try to stay on the flexible wire 3, the birds are bent downward when the weight of the birds is applied, and the birds are brought into contact with the needle 11 to prevent the birds from being parked. Moreover, since it has flexibility (softness | flexibility), it becomes an unstable scaffold with respect to birds, and bird-resting is prevented.
In particular, as shown in FIGS. 6 to 10, when the flexible wire 3 is fixed in a cantilever shape, when the nesting material comes into contact, the nesting material is shaken well to repel the nesting material and prevent deposition. In addition, since it becomes a more unstable scaffold for birds, the effect of preventing bird parking is improved.

  The present invention can be changed in design, and is not limited to the embodiment in which the illustrated column is three columns, and the column may be only one column, two columns, or four columns or more. Further, the shape of the top portion 10 of the needle 11 may be a conical shape having a sharp point or a sword shape. The needle 11 may be formed in a quadrangular pyramid shape. The needle 11 may be a round bar type or a square bar type having a straight outer peripheral surface. Moreover, you may comprise the bird-holding prevention main-body part 1 as an assembly. As shown in the figure, the base end connecting member 15 is not limited to the shape in which the longitudinal direction connecting member 12 and the width direction connecting member 13 are arranged in a rectangular shape in a plan view, and the shape arranged in a U shape in a plan view, A plurality of needles 11 may be connected by arranging the longitudinal direction connecting member 12 and the width direction connecting member 13 in an uneven wave shape in a plan view. The proximal end connecting member 15 may be formed in a strip shape. Further, the longitudinal direction connecting member 12 and the width direction connecting member 13 are free to have a bowl-like shape, a rod-like shape, a plate-like shape or the like (a plan view shape or a cross-sectional shape). Further, in FIG. 3, the ridge line connecting the tops 10 of the needles 11 constituting a horizontal row in a front view has a trapezoidal upper half shape having a straight line part and an obliquely slanted part extending downward from both ends of the straight line part. It may be formed so as to be a ridge line T or an arch (semi-arc) ridge line T. The material of the bird-holding prevention main body 1 is an insulating material such as plastic, for example, polypropylene. Moreover, the cross-sectional shape of the flexible wire 3 is free, such as circular or rectangular.

  As described above, the bird parking prevention apparatus of the present invention includes a bird parking prevention main body 1 in which a plurality of upwardly protruding needles 11 are arranged in the longitudinal direction N, and a longitudinal end of the bird parking prevention main body 1. The arc-shaped flexible wire 3 that is fixed to the portion 1E and bends in an upward convex shape is provided, so that the landing of birds by both the needle 11 of the bird-preventing main body 1 and the arc-shaped flexible wire 3 is provided. This makes it more difficult to reliably park birds. Bird's nest material does not accumulate between the needles 11 and 11, and nesting can be reliably prevented.

  A ridge line S connecting the apexes 10 of the plurality of needles 11 arranged in the longitudinal direction N is formed in an upward convex arch shape when viewed from the side, and the arcuate flexible wire 3 is roughly aligned with the ridge line S when viewed from the side. Since the nesting material is arranged along the nesting material, the nesting material can be smoothly slid down or repelled to prevent nesting.

  Alternatively, the plurality of needles 11 are arranged in parallel so that the height dimension H is different in the lateral direction W, and the top 10 of the needles 11 in the high needle column 8b among the plurality of needle columns 8a, 8b, 8c is arranged. The connecting ridge line S is formed in an upwardly convex arch shape when viewed from the side, and the arc-shaped flexible wire 3 is disposed so as to be substantially along the ridge line S when viewed from the side. In addition, the nesting material can be smoothly slid down or reliably reinforced to prevent nesting.

  In addition, since the plurality of arc-shaped flexible wires 3 are arranged in parallel to each other, the flexible wires 3 are easily shaken, and the nesting material can be surely repelled to prevent nesting. In addition, when the birds try to stay on the flexible wire 3, the birds swing well and become unstable, thereby preventing birds from standing.

  Alternatively, since there are a plurality of the arc-shaped flexible wires 3 and they are arranged so as to intersect with each other in plan view at the longitudinal central portion 1F of the bird-preventing main body 1, Accumulation of nesting material can be reliably prevented. Moreover, the arch shape of the flexible wire 3 can be easily held, and can be slid down or played without being defeated by the nesting material.

  In addition, a bird-preventing main body 1 in which a plurality of needles 11 protruding upward are arranged in the longitudinal direction N, and an arc-shaped flexible wire 3 that is fixed to the bird-preventing main body 1 and is bent in an upward convex shape. , And the predetermined or all of the plurality of needles 11 are the fixing needles 11z to which the arc-shaped flexible wire material 3 is fixed. Connection is possible without using a special connection member 9, and the number of parts may be two, which can be easily and inexpensively manufactured.

  Further, a locking projection 71 having a stepped surface 71a having an orthogonal surface is projected from the base end portion of the fixing needle 11z on the axis L11 of the fixing needle 11z, and the end portion 30 of the arc-shaped flexible wire 3 is projected. The cylindrical portion 36 is provided on the lower end opening inner peripheral edge portion 36a of the cylindrical portion 36, and the locking claw portion 61 is projected from the cylindrical portion 36 so that the cylindrical portion 36 of the arc-shaped flexible wire 3 is attached to the fixing needle 11z. The locking claw portion 61 is locked to the stepped surface 71a and the arc-shaped flexible wire 3 is fixed to the bird-preventing main body 1 so that the flexible wire fixing operation can be performed easily and quickly. . Thick (larger) cylindrical part than the flexible wire part 37 of the flexible wire 3 even when using a long work gripping tool in construction in a live line (power transmission) state or construction in a high place 36 can be gripped, and positioning for fitting the cylindrical portion 36 to the fixing needle 11 is easy, and a safe and quick operation can be realized.

  Further, since the locking convex portion 71 has a guide gradient surface 71g that gradually approaches the needle outer peripheral surface 80 from the radial outer edge 71b of the step surface 71a toward the needle tip side, the lower end opening of the tubular portion 36 is smoothly formed. The engaging claw portion 61 can be easily and quickly engaged with the engaging convex portion 71 by expanding the diameter by elastic deformation.
