Description

  The present invention relates to a bird collision prevention transparent plate used for a soundproof wall of a highway or a window glass of a building.

  Generally, a highway in a residential area is provided with a light shielding plate or a soundproof wall along the road so that light emitted from a car light or noise does not enter the residential area. In addition, there are places where a transparent plate is attached to a part of the light shielding plate or soundproof wall so that the scenery can be seen. However, in places where transparent plates (also called translucent plates) are attached, it is impossible to recognize that birds have plates, so there are many accidents in which birds die by colliding with transparent plates. It is.

  In addition, it is difficult for birds to recognize that window glass with a half-mirror function and general window glass used in buildings such as buildings have an accident where birds collide with the window glass. Many have occurred.

  In recent years, modern high-rise buildings in large cities, in particular, tend to have large glass windows and glass walls throughout to allow sunlight to enter the room. For this reason, the number of accidents in which migratory birds can not be recognized as window glass during flight and die due to death is increasing year by year. Furthermore, at night, many migratory birds collide with the illuminated high-rise buildings, or at night when fog and low clouds sag, the direction sense is distorted by the light, and the illuminated high-rise buildings Around New York's skyscrapers, people swung around and either fell to the ground with exhausted physical strength or crashed into buildings and died. The number of birds was 5% of all birds in the United States, or nearly 1 million. There are reports that many migratory birds die in accidents that collide with buildings every year. To prevent this, every year, in April and May, the spring season, and September-October, the autumn season, we turn off the night lights on the famous skyscrapers in New York to prevent birds from colliding. I'm trying.

  For this reason, Japanese Patent Application Laid-Open No. 7-289142 “Avian Collision Prevention Glass” is proposed to prevent birds from colliding with the window glass. In this structure, a plate glass is used in which a geometric pattern is applied to the transparent glass plate in a substantially uniform distribution on one side. Further, a plurality of means for adhering a sheet on which a geometric pattern is printed in a substantially main region to one side of a plate glass or attaching a geometric pattern is used.

  However, since JP-A-7-289142 is a transparent glass plate, there is a risk of cracking, and since the geometric pattern is deposited almost uniformly distributed over the entire surface, the amount of light collected is reduced and the room is There was a possibility that the wonderfulness of the scenery to be seen was halved or could hardly be seen. Furthermore, since the geometric pattern is adhered to one side of the transparent glass plate with an adhesive or adhesive sheet, the adhesive or adhesive sheet may be peeled off over a long period of time, and may be faded by wind or rain. .

  On the other hand, Japanese Patent Application Laid-Open No. 2006-63744 proposes a translucent soundproof wall proposed for preventing birds from colliding with each other. In this structure, a transparent soundproof board is attached to a support column, and a bird of prey image imitating a bird of prey in a plane is depicted on the soundproof board. This effect is not limited by the background color tone, and the bird can be visually recognized as a bird of prey, so that a high bird collision prevention effect can be obtained regardless of the installation location.

  However, according to Japanese Patent Application Laid-Open No. 2006-63744, a seal on which a flying bird of prey is depicted in a plane is attached to a soundproof plate. For this reason, the portion on which the bird of prey drawing is depicted becomes opaque and the translucency deteriorates, and therefore, it is up to the size of the bird of prey drawing in the drawing shown in FIG. Considering the nature, it could not be drawn large on the entire plate. Further, the seal adhesive peeled off over a long period of time, and there was a risk of fading due to wind and rain or ultraviolet rays.

  An object of the present invention is to provide a bird collision prevention transparent plate that prevents the collision of birds, the light intensity is not halved, and the view of the scenery from the window is not halved.

  The present invention has been made in view of the above situation, that is, a structure in which a figure of an animal or an obstacle afraid of birds is displayed as dots on the transparent plate body. Moreover, it is preferable that the above-mentioned point is hollowed out. Further, the transparent plate body may be made of synthetic resin, or the transparent plate body may have a function of reflecting ultraviolet rays.

  It is easy and reliable to prevent birds from colliding by displaying on the transparent plate main body (1) the graphic (2) such as animals or obstacles that are afraid of birds by points (21). It will be something that can be done. For this reason, bird strike prevention is possible. Moreover, even if a large figure (2) such as an animal or obstacle that fears birds is displayed in large size, the amount of light collected from the window is not reduced so much, and it is possible to warn the birds of collision prevention. It is possible to make the view not halved. Furthermore, when the product of the present invention is attached to a large window glass of a high-rise building, it becomes possible to recognize the window glass as an obstacle while the migratory bird is flying. By displaying the company's trademark and tagline as 2), it can be used to improve the company's image and the advertising effect can be expected.

  By eliminating the point (21) as in claim 2, a larger figure (2) can be displayed without reducing the amount of light collected from the window than in claim 1 and preventing collision with birds. This warning becomes more effective, and the view of the scenery from the window can be reduced by half.

  By making the transparent plate body (1) made of synthetic resin as shown in claim 3, it is possible to prevent birds from colliding, especially when the product of the present invention is attached to a part of a soundproof wall of a highway as a light transmitting plate. Therefore, the damage to the transparent plate main body (1) due to the collision of birds as in the prior art is eliminated, and the useful life of the transparent plate main body (1) is longer than before and the maintenance is easy. Moreover, even if a bird collides with the transparent plate body (1), it does not break and scatter like conventional glass, and there is no fear of breaking.

  By providing the transparent plate main body (1) with a function of reflecting ultraviolet rays as shown in claim 4, birds can avoid collision with the transparent plate main body (1) with their eyes and also by irradiation with ultraviolet rays by reflection. Since birds can avoid collision with the transparent plate body (1), it is possible to more reliably prevent birds from colliding.

It is explanatory drawing which displayed the figure of the tiger in embodiment of this invention. It is explanatory drawing which displayed the figure of the eyelid in embodiment of this invention. It is explanatory drawing which displayed the figure of the eye in embodiment of this invention. It is explanatory drawing which showed the cross section of this embodiment.

  An embodiment of the present invention will be described with reference to FIGS. (1) is a transparent plate body of a glass plate or a synthetic resin plate, and the transparent plate body (1) is preferably made of a synthetic resin. The transparent plate main body (1) may display a graphic (2) to be described later on one side of the transparent plate main body (1). However, the transparent plate main body (1) is newly transparent from above the transparent plate main body (1) displayed on one side. It is good also as a laminated board which laminated | stacked the board main body (1) (refer FIG. 4). Further, the figure (2) may be displayed on a transparent film, and the transparent film may be sandwiched between two transparent plate bodies (1).

  (2) is a figure displayed with a point (21) on the transparent plate main body (1), and as the figure (2), an animal feared by birds, for example, an eagle, tiger, eagle, hawk or eye is displayed. good. The obstacle may be a large wall, a rock or a building that can easily be seen by birds during the flight, and the company's trademark or tagline is displayed to show the obstacle figure (2). It is also good. The figure (2) at this time can be used to improve the image of the company. Further, when the graphic (2) is displayed as the point (21), it is preferable that the graphic (2) is displayed as the point (21) having a predetermined size. Further, the point (21) may be a black circle or a colored circle, but it is preferable that the point (21) is hollow. In addition, when displaying the said figure (2), it is good to use the acrylic silicon-type ink etc. which are excellent in the weather resistance and durability which can be printed on a transparent plate main body (1). Further, the figure (2) may be printed on the transparent sheet with the ink, and the sheet may be adhered to one side of the transparent plate body (1). Furthermore, the shape of the point (21) is not limited to a round shape, and may be a polygonal shape such as a square shape or a triangular shape.

  Further, in order to provide the transparent plate body (1) with a function of reflecting ultraviolet rays, a metal oxide such as titanium oxide or zinc oxide is applied to one side of the transparent plate body (1) to reflect the ultraviolet rays. Easy to use. In addition, it is good also as what applied the ultraviolet absorber which not only reflects an ultraviolet-ray but absorbs an ultraviolet-ray to a transparent plate main body (1). By applying this ultraviolet absorber, the role of notifying birds of the presence of the transparent plate body (1) is fulfilled.

  Next, the operation of the present invention will be described. First, the product of the present invention is installed on a part of a soundproof wall of an expressway or attached to a window glass of a building. At this time, especially in the room, since the figure (2) is displayed as the point (21), it is far from the case where the figure (2) is drawn on the transparent plate body (1) by a general method. Therefore, the amount of light collected is large. That is, if the light can be taken from the interval between the points (21), and the point (21) is a light-colored circle or the like, the light can be taken in a state slightly reduced from the point (21) itself. At this time, if the point (21) is hollowed out, the lighting condition is further improved.

  On the other hand, in the outdoor bird, the figure (2) is displayed as a point (21), but since the figure (2) is far away from the flying bird, the point (21) is a line. Since the figure (2) drawn by the point (21) is an animal or an obstacle feared by the birds, the birds do not approach the transparent plate body (1). As a result, even the transparent plate body (1) can almost prevent birds from colliding.

  In particular, if the product of the present invention is installed on a part of the soundproof wall of an expressway, there will be almost no bird's rear-end collision, and conventional bird carcasses disposal, road surface and translucent plate cleaning work, translucent plate repair And no need for replacement, maintenance of the highway is easy and management costs are reduced.
