  However, the above measures for preventing damage caused by birds may reduce the effect of reflecting birds by reducing the effect of reflecting light by long-term use, or by getting used to birds. There is a problem that the present invention intends to solve.

  The present invention has been made in order to solve this problem in view of the above situation, and the invention of claim 1 is directed to the main surface of one of the elongated strip-shaped stainless steel plates. The coil portion is formed in a spiral shape, and is provided in each of the elongated coil-shaped coil portions having flexibility in the axial direction, the radial direction, and the circumferential direction, and both end portions in the axial direction of the coil portions. It is a bird damage prevention apparatus characterized by including a latching | locking part.

  Next, an embodiment of the present invention will be described based on the drawings of FIGS.

  In the drawings, reference numeral 1 denotes a bird guard as a bird damage prevention device for preventing damage caused by birds such as crows, chicks, pigeons, sparrows, wagtails, long-tailed birds, etc., and the bird guard 1 is an elongated strip-shaped stainless steel. The coil part 10 which is an example of the latching | locking part comprised by winding the board A helically, and the hook part 20 attached to each of the both ends of the axial direction of this coil part 10 are comprised. Has been.

  As shown in FIG. 2, the coil unit 10 is a spring machine formed in a coil spring shape having elasticity by a strip-like stainless steel plate A, and is easily caused by wind or shaking of an installation place accompanying the wind. It moves erratically and repels birds. Here, the stainless steel plate A is a plate-like body made of stainless steel having high corrosion resistance, in which both plate surfaces, that is, the inner surface 11 and the outer surface 12 are mirror-finished.

  Further, the coil portion 10 is configured to be flexible by being spirally wound in a state where the inner surface 11 which is one main surface of the stainless steel plate A is directed in the central axis direction. In other words, the coil portion 10 is formed in an elongated cylindrical shape formed by bending the stainless steel plate A with the same curvature in the longitudinal direction of the stainless steel plate A. That is, the coil portion 10 is formed in a parallel normal spiral shape in which the diameter from the center position to the stainless steel plate A and the distance between the stainless steel plates A are equal, and the axial direction and diameter of the coil portion 10 are the same. It is configured to have flexibility in each of the direction and the circumferential direction (twist direction). Furthermore, this coil part 10 is wound in parallel so that the distance between adjacent stainless steel plates A is equal.

  Specifically, the coil part 10 has a thickness dimension of, for example, 0.1 to 0.5 mm (preferably 0.3 mm), for example, a stainless steel plate A having a width dimension of 1 to 5 mm (preferably 3 mm). For example, 1-5 mm (preferably 3 mm) with an interval (pitch), for example, 10 to 50 mm (preferably 23 mm) having a diameter dimension of 10 to 50 mm (preferably 23 mm). It is formed in the shape of an elongated coil having a length dimension (preferably 2 m).

  On the other hand, the hook portion 20 is formed by bending a stainless steel bar B having a diameter of 1.5 mm, for example, into a substantially J-shape and being bent 180 degrees. The base 21 on the end side is further bent 180 degrees in a J-shape to form a welded portion 22. The welded portion 22 is bridged and welded between the inner side surfaces 11 of the stainless steel plate A located at the end portion of the coil portion 10 in the axial direction. Here, the end portion of the stainless steel plate A of the coil portion 10 is wound around and fixed to the proximal end portion of the welded portion 22 of the hook portion 20.

  The hook portion 20 is attached in a state in which the bending direction of the hook portion 23 curved in a J-shape on the tip side of the hook portion 20 is aligned with the radial direction of the coil portion 10. Further, the hook portion 23 is curved with a curvature substantially equal to the diameter of the coil portion 10, and the stainless steel plate A constituting the coil portion 10 is formed in a state where the axial direction of the coil portion 10 is linear. It is comprised so that it may not protrude outside the outer surface 12 which is another main surface. That is, the hanging portion 23 is formed to have a width dimension substantially equal to the diameter dimension of the coil portion 10. Furthermore, the front end portion of the hook portion 23 is provided along the axial direction of the coil portion 10.

  In the embodiment of the present invention configured as described above, the bird guard 1 is configured such that the coil portion 10 is hooked around a place where bird damage such as noise, excrement, and eating damage is assumed. By installing so that it can move freely, the coil part 10 moves largely and irregularly in the axial direction, the radial direction, and the torsional direction due to the wind and the shaking of the installation location accompanying the wind.

  In particular, the coil portion 10 is formed long in the axial direction and is configured to have flexibility in each of the axial direction, the radial direction, and the torsional direction, so that the wind is weak or the shaking of the installation place is small. Even if it is a case, it moves relatively large, and it is not a simple vibration but an irregular motion with no predictability.

Further, the coil portion 10 is formed of a stainless steel plate A, and the inner surface 11 of the stainless steel plate A constituting the coil portion 10 is directed in the central axis direction so that the diameter dimension from the center position to the stainless steel plate A, and the stainless steel plate Since each of the spacing dimensions between A is wound in a regular spiral shape, the outer surface 12 of the stainless steel plate A is in a state of being directed in the radial direction of the coil portion 10, and the light irradiated to the coil portion 10. Is greatly diffused by the outer surface 12.
By the way, when the bird guard 1 of the present invention was installed in a place where a crow flew in an outdoor test site where others could not enter and could not be seen from outside, more than one year had passed. However, it has been confirmed that crows do not fly and come close to it, and the usefulness of the present invention is confirmed.

  Therefore, because of the irregular and unpredictable movement of the coil part 10, birds are not accustomed even if used for a long time, and the use of the stainless steel plate A makes it difficult to rust even if installed outdoors, such as CD or Since there is little suppression of irregular reflection that can occur when a DVD is used, the effect of irregular reflection of the irradiated light is unlikely to decrease. Therefore, birds can be efficiently avoided over a long period of time.

  That is, by installing the bird guard 1 in which the present invention is implemented in a place where birds approach, birds can be prevented from approaching and birds can be avoided for a long period of time, so that blueberries, strawberries, cherries, strawberries, watermelons, Birds such as corn and other fruits and cereals are cultivated outdoors, houses and greenhouses, fish farms, garbage dumps (garbage stations), verandas of manure-affected condominiums, schools, shrines and temples, etc. Damage from birds in the place where they are received can be prevented continuously over a long period of time.

  In addition, by installing the bird guard 1 in which the present invention is implemented in the poultry farm, migratory birds can be prevented from entering the poultry farm to prevent avian influenza infection (countermeasures against bird flu), and in construction structures such as high-voltage power transmission towers. It is also effective for measures against bird damage (countermeasures for crows) by creating nests.

  Of course, the present invention is not limited to the above-described embodiment, and the hook portions 20 attached to both ends of the coil portion 10 are not shaped to be bent by 180 degrees in a substantially J shape, Any other configuration and shape are possible as long as they can be locked. Furthermore, for example, an auxiliary locking portion having locking hooks formed at both ends, such as an S-shape or C-shape, is used, and one locking hook of the auxiliary locking portion is attached to the protective arm in which the present invention is implemented. Of course, it is possible to engage with the middle part of the bird 1 and attach the other engagement hook to the building or plant side.

  Further, although the coil portion 10 is formed in a regular spiral shape in which the diameter from the center position to the stainless steel plate A and the distance between the stainless steel plates A are equal, it is possible in each of the axial direction, the radial direction, and the circumferential direction. If the configuration has flexibility, the configuration in which the diameter dimension of the coil portion 10 gradually increases as it progresses in the axial direction, or the configuration in which the interval dimension of the coil portion 10 gradually increases as it progresses in the axial direction, It is also possible to adopt a configuration in which the diameter dimension and the interval dimension change regularly.

  EXAMPLES Hereinafter, although an Example demonstrates this invention further in detail, this invention is not limited to the following Example.

<Example 1>
When the bird guard 1 in which the present invention is implemented is attached to an outdoor tree 30 such as a relatively large fruit tree, as shown in FIG. 3, the coil portion 10 of the bird guard 1 is swayed by wind or the tree 30. Since one hook portion 20 of the bird guard 1 is hooked and fixed to a branch of a tree 30 around a place where bird damage is assumed, the bird guard 1 is fixed. After the coil portion 10 of the bird device 1 is slightly bent and entangled with a branch of the tree 30, the other hook portion 20 of the bird guard 1 is hooked on the branch of the tree 30 and fixed.

  As a result, because the coil portion 10 of the bird guard 1 moves irregularly due to wind or shaking of the tree 30, birds can be avoided from the tree 30 to which the bird guard 1 is attached. Bird damage can be prevented. Further, when it is desired to further increase the movement of the coil portion 10 of the bird guard 1, it is preferable that the hook portions 20 at both ends are hooked on the tree 30 and fixed while the coil portion 10 is further bent. Furthermore, when the tree 30 in which bird damage is assumed is large or the place in which bird damage is assumed is wide, it can be dealt with by attaching a plurality of bird guards 1 to the tree 30.

<Example 2>
When the bird guard 1 in which the present invention is implemented is attached to the fence 40, as shown in FIG. 4, the hook parts 20 at both ends are fenced with the coil part 10 of the bird guard 1 bent. 40 is hooked and fixed at a predetermined position, and the intermediate portion of the coil portion 10 is hooked on the fence 40 and fixed. Furthermore, when a plurality of bonsai trees 41 are placed in a place surrounded by the fence 40 and the bird damage of the bonsai trees 41 is prevented, the coil unit 10 is placed on the bonsai trees 41 as shown in FIG. It is preferable to install the bird guard 1 so as to pass through.

  As a result, when the coil portion 10 of the bird guard 1 moves irregularly due to wind or the swing of the fence 40, birds can be avoided from the bonsai 41 or the like placed at the place where the bird guard 1 is attached. Therefore, bird damage of these bonsai 41 can be prevented.

Are hooked between the fences 51 of the garbage collection place 50 and fixed. At this time, when the garbage collection place 50 is wide, the wide garbage collection place 50 can be handled by attaching the plurality of bird guards 1 while being shifted up and down between the fences 51.

  As a result, because the coil portion 10 of the bird guard 1 moves irregularly due to wind or shaking of the fence 51, birds can be avoided from the garbage collection place 50 to which the bird guard 1 is attached. It is possible to prevent bird damage such as eating and rubbing of the garbage 52 put out at the collection place 50.

<Example 4>
When the bird guard 1 in which the present invention is implemented is attached using a tree 61 planted around the garbage collection place 60, as shown in FIG. 7, one hook portion 20 of the bird guard 1 is provided. Is hooked on the top of the tree 61 and fixed, and the other hook of the bird guard 1 is attached to the fence 63 installed on the rear side of the net 62 covering the garbage (not shown) put out at the garbage collection place 60. The portion 20 is appropriately entangled, adjusted in length, and hooked and fixed. At this time, if the garbage collection place 60 is wide, the large garbage collection place 60 can be dealt with by shifting the plurality of bird guards 1 to the left and right in parallel.

  As a result, because the coil portion 10 of the bird guard 1 moves irregularly due to wind or shaking of the tree 61, birds can be avoided from the surrounding garbage collection place 60 to which the bird guard 1 is attached. It is possible to prevent bird damage such as devourage of garbage put out at the garbage collection place 60.

<Example 5>
When the bird guard 1 in which the present invention is implemented is installed in a large greenhouse 70 that can be partially opened, the coil portion 10 of the bird guard 1 is bent as shown in FIG. In this state, the hooks 20 at both ends of the bird guard 1 are hooked and fixed to a frame 71 constituting the greenhouse 70, a lighting fixture 72 installed in the greenhouse 70, and the like. At this time, in order to prevent bird damage in the greenhouse 70 when opened, the plurality of bird guards 1 are crossed so that the coil portion 10 of the bird guard 1 passes above the greenhouse 70. It attaches in the greenhouse 70 by making it.

  As a result, when the coil portion 10 of the bird guard 1 moves irregularly by the wind flowing in the open greenhouse 70, the birds are removed from the plants 73 growing in the greenhouse 70 to which the bird guard 1 is attached. Since it can be avoided, bird damage in the greenhouse 70 can be prevented.
