Description

  The present invention relates to an apparatus for preventing birds such as pigeons and crows from flying, and preventing contamination and damage to buildings due to dung damage and nesting.

  Various damage caused by the arrival of birds at various stadiums such as racetracks, bicycle racetracks, baseball stadiums, athletic stadiums, shrines, stations, underpasses on roads and tracks, condominiums, factories, warehouses, etc. ") Has become a major problem in recent years. As measures against damage to birds, we used methods such as human-type kakashi, eagle-shaped artificial birds, eyeballs, reflectors, and other visual devices, methods using auditory devices such as explosive sounds, and bird-proof nets. A method using a plurality of needles, a method using a repellent, a method using an electric shock, and the like.

  Each measure is used in various places depending on the application. For example, in a method using a bird-proof net, if it is constructed reliably, it is possible to prevent the arrival of birds almost certainly. However, the appearance is impaired, and if there is a gap in a part, birds can enter. Moreover, if a drug is used, a certain degree of effect can be expected, but there are problems such as animal welfare and safety.

  1A and 1B are schematic views showing a stadium stand, where FIG. 1A is an overall configuration diagram, and FIG. 1B is an enlarged view of part A. FIG. As shown in FIG. 1, there are many special viewing seats 1 called box seats in the vicinity of the top of a stadium such as a racetrack. Since the special seat 1 is at a high place, the window cleaning is performed with the window cleaning gondola 4 suspended from the roof 2 or the like by the wire 3. A gap 5 having a width of about 300 mm exists in order to move the window cleaning gondola freely left and right and up and down through the wire 3 on the lower surface of the roof 2. A pigeon or the like may enter the roof 2 from the gap 5.

  If the gap 5 is covered with a bird net, the wire 3 of the gondola 4 cannot be moved freely. Although it is conceivable to narrow the gap 5, the wire 3 is likely to come into contact with the inner surface of the gap 5, which is not suitable for practical use. On the other hand, a bird net is often used as a measure to prevent the apartment from flying into the balcony. However, the bird net is made of heat-sensitive material such as polyester, so it can be used at high temperatures such as a chimney of a water heater. It cannot be used near the part.

  The present invention has been made in order to solve the above-described problems of the prior art, and a bird-proof net due to a gap provided for moving some object such as a gondola wire, heat or other reasons. It is an object of the present invention to provide a bird protection apparatus for gaps that could not be prevented by conventional bird damage countermeasures, such as gaps that are formed because the cable cannot be stretched.

  The present invention relates to a bird proof having “an attachment portion that fixes one end of a plurality of first metal rods arranged in parallel and at equal intervals in the same plane, and a needle portion that opens the other end of the first metal rod. The gist of the present invention is a birdproof device characterized in that at least the tip of the needle portion is made of an elastic material.

  In this birdproof device, it is preferable that the attachment portion is configured by joining a plurality of first metal bars and a plurality of second metal bars perpendicular to the first metal bars. Moreover, it is preferable that a spring is attached to the tip of the needle portion. The first metal bar is preferably made of a spring stainless steel wire.

  The bird protection device of the present invention is a gap for a gondola wire for which a conventional bird protection device could not be installed, and for a chimney of a water heater that was ineffective with a conventional bird protection device. It can be installed even in places where gaps are unavoidable.

  2A and 2B are schematic views showing an example of the configuration of the birdproof device according to the present invention. FIG. 2A is a top view and FIG. 2B is a side view. As shown in FIG. 2, for example, the birdproof device 6 according to the present invention includes a plurality of first metal rods 7 arranged in parallel and at equal intervals in the same plane, and one end of the first metal rod 7. And a needle portion 9 having the other end of the first metal rod opened. And the spring 10 is attached to the front-end | tip of the needle part 9 as an elastic material, for example.

  The space | interval of the 1st metal rod 7 should just be a space | interval of the grade which birds cannot pass. However, if the interval is too narrow, the number of metal bars increases and only the mass of the birdproof device is increased. Moreover, although the diameter of the 1st metal rod 7 is determined by the relationship between the mass of the bird-proof apparatus 6, and required mechanical strength, it is desirable to set it as 1.5-2.5 mmphi.

  The length of the first metal rod is determined by the relationship with the size of the gap to be installed. However, birds cannot enter the gaps that are too narrow, so bird protection measures are not necessary in the first place. Therefore, for example, when assuming a gap with a width of 300 mm, the first metal rod 7 is preferably about 50 to 150 mm so that the length of the needle portion is about 100 to 200 mm. In addition, when attaching an elastic body such as the spring 10 to the tip of the needle portion 9, it is possible to make a bird protection device corresponding to various gaps by changing the length of the spring at the work site. It is not necessary to prepare the first metal rod.

  There are no particular restrictions on the number of first metal rods 7. In the example of the above gondola, the length of the gap may reach several tens of meters. Therefore, it is desirable to prepare a birdproof device to which as many first metal rods 7 are fixed as possible. If the number of the rods 7 is too large, the mass increases and the size also increases, so that the workability during transportation, loading, mounting, etc. is deteriorated. For this reason, it is preferable that the number of the birdsproof device 6 is 500 mm or less with the first metal rod 7 fixed. For example, when the width of the birdproof device 6 is 480 mm and the interval between the first metal rods 7 is 40 mm, the number is 13 and when the interval between the first metal rods 7 is 120 mm, the number is 7. When the gap is long, a plurality of bird protection devices can be mounted side by side.

  FIG. 3 is a schematic view showing an example of an attachment state of the birdproof device according to the present invention, wherein (a) is a top view and (b) is a side view. As shown in FIG. 3, for example, the birdproof device 6 according to the present invention is attached to each end portion of the support 12 that constitutes the gap 5, such as a building beam, a roof lower surface, and the like. In this case, the birdproof device 6 according to the present invention is attached so that the respective needle portions 9 face each other.

  Since the bird-proof device 6 according to the present invention has at least the tip of the needle portion made of an elastic body, for example, when a gondola wire or the like is passed through the gap 5, the wire is connected to the needle portion 9 of the bird-proof device. Even if it contacts, a needle part and a wire will not be damaged.

  Although the attachment state of the attachment portion 8 and the support 12 is not shown, the attachment portion 8 and the support body 12 can be joined using screws, nails, tuckers, or other fasteners. Moreover, about the location where joining is difficult, you may join using a double-sided tape, an adhesive agent, etc.

  As the attaching part 8, what welded to the metal plate which threaded the 1st metal rod 7, for example can be used. However, if it comprises a metal plate, the mass increases and the degree of freedom of joining to the support 12 becomes worse. Therefore, as shown in FIG. 3, the mounting portion 8 is formed by joining a plurality of first metal rods 7 and a plurality of second metal rods 11 perpendicular to the first metal rods 7. Is preferred. If the first metal rod and the second metal rod are configured in this way, the width of the bird protection device 6 can be adjusted by cutting the second metal rod at an appropriate location at the work site. There is also an advantage that it is not necessary to prepare various sizes.

  FIG. 3 shows an example in which three second metal rods 11 are used. However, the joining is not limited to the example in FIG. 3 because two or more metal rods 11 can be joined. However, when the number of the second metal rods 11 is increased, the mass is increased and the material cost and the manufacturing cost are increased. Therefore, the number of the second metal rods is preferably 5 or less.

  In the example shown in FIG. 3, the facing needle portions 9 are attached so as to be substantially in a straight line, but the configuration is not limited to this. For example, in the case of a birdproof device in which the interval between the first metal rods 7 is 120 mm, it can be configured by shifting in the width direction by 60 mm.

  It is desirable that at least the tip of the needle portion is made of an elastic material. As the elastic material, in addition to the spring shown in FIG. 3, rubber or a material attached with an elastic metal rod thinner than the first metal rod 7 can be used. It is desirable to use a spring for reasons such as durability and ease of joining. At this time, for example, the inner diameter of the spring is set to be substantially equal to the outer diameter of the first metal rod, and the spring can be fitted into the tip of the first metal rod and fixed with an adhesive or the like. Further, the first metal rod 7 itself may be made of an elastic material. In this case, for example, a stainless steel wire for spring (JIS G 4314) can be used.

  In the example shown in FIG. 3, the spring 10 is attached only to the tip of the needle portion 9 of one of the birdproof devices 6, but the spring 10 may be attached to the tip of the needle portion 9 of both of the birdproof devices 6. When the first metal rod 7 itself is made of an elastic material, the spring 10 does not have to be attached to the tips of the needle portions 9 of both the bird protection devices 6.

  FIG. 4 is a side view showing another example of the state of attachment of the birdproof device according to the present invention. As shown in FIG. 4, the birdproof device according to the present invention can be used by bending a part of the first metal rod 7. That is, the first metal rod 7 can be attached to the side surface of the support 12 by substantially bending the position in the vicinity of the attachment portion 8.

  The bird protection device of the present invention is a gap for a gondola wire for which a conventional bird protection device could not be installed, and for a chimney of a water heater that was ineffective with a conventional bird protection device. It can be installed even in places where gaps are unavoidable.
