Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fecal damage prevention device. More specifically, the present invention relates to a pigeon dropping prevention device used for protecting temple roofs, bridge bridges, roofs of warehouses and relatively large houses, and eaves from the damage of pigeons.

[0002]

[Prior art]

 Since pigeons have often gathered on temple roofs, bridge bridges, warehouses and roofs of relatively large houses, and the back of eaves, pigeon droppings have often been a problem in those areas. In temples, etc., nets are stretched over the entire roof, and in the case of bridges with bridges, nets are stretched around the bridges to prevent pigeons from approaching the relevant places.

[0003]

[Problems to be solved by the device]

 However, the method of laying a net around the roof of the temple or the bridge of the bridge had the following problems. The roofs of the temples and the nets stretched around the bridges around the bridges are not beautiful to look at, and the scenery is significantly impaired especially in the case of temples. In the bridge girder, it is often inconvenient for bridge maintenance because the pigeon droppings adhered to it. In the case of a temple roof, a net is stretched over the entire roof, and in the case of a bridge, the net is stretched around the bridge and up to the back side of the bridge body above the bridge. Get higher Getting rid of dead pigeons entangled in the net is very time consuming and the work is very dangerous.

[0006] Furthermore, since no measures have been taken for the roof of a warehouse, a relatively large house, or the back of an eaves, there are the following problems. The current situation is that pigeons stop on the roof or the eaves and make dung, and the dung makes the roof and the eaves unsightly, and the dung causes damage to the gutter. In the case of a warehouse, since the entrance is often open, pigeons enter the interior of the warehouse to form nests and drop feces when entering or leaving the nest. There are also many damages, such as the things that are left behind being polluted. From the rainy season to the summer, the feces give off an offensive odor and make the surroundings uncomfortable. During the breeding season, dozens of birds form a group and roar around the roof in the early morning, making it very noisy and unpleasant.

On the other hand, at present, pigeons that have been kept in ordinary households have become wild and have propagated in large quantities, and there is no way to prevent the breeding. There is no doubt that it will become a social problem.

In view of such circumstances, the present invention prevents the pigeon from stopping at the location by installing it on the roof of the temple, the bridge of the bridge, the roof of the warehouse / relatively large house, or the back of the eaves. The aim is to provide a pigeon dropping prevention device for protecting roofs and the like from pigeon dropping damage.

[0007]

[Means for Solving the Problems]

 The bird damage prevention device of the present invention is composed of a wire rod having a thickness such that a pigeon cannot be stopped and a support rod supporting the wire rod, and the height of the support rod is 5 cm to 30 cm.

[0008]

[Action]

 In the pigeon dropping prevention device of the present invention, since the thickness of the wire rod is such that the pigeon cannot stop, the pigeon cannot use the wire rod as a perch. Since it is supported and stretched at a height of ~ 30 cm, if the pigeon flaps its wings when attempting to land near the bottom of the wire, the wings will touch the wire, so it will not be possible to land near the bottom of the wire.

[0009]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a pigeon dropping prevention device A according to an embodiment of the present invention. This pigeon dropping prevention device A is composed of a wire rod 1 and a support 2.

As the wire rod 1, any wire rod can be used without particular limitation as long as the wire rod has a thickness that does not allow the pigeon to stop. In other words, when the pigeon stops on the wire rod, it has the habit of holding the body by holding the wire rod inside the claws, so that the diameter of the wire rod is small and the portion of the wire rod against which the inner surface of the pigeon claws abuts. If the size is very small, the pigeon cannot stably hold the wire on the inside of the claw, so that the pigeon cannot hold its body stably on the wire and cannot stop on the wire. Specifically, iron wire, coated iron wire, copper wire, coated copper wire, nylon thread, tegu thread, etc. can be used, but in this example, strength, durability, ease of processing, price, etc. are taken into consideration. Then, 20 # (0.8 mm diameter) copper wire was used.

The stanchion 2 supports the wire 1 and attaches the wire 1 to a height at which the wings come into contact when the dove flaps to stop at the building, that is, a height of 5 cm to 30 cm from the building. If possible, there is no particular limitation on the material, shape, etc., and any material can be used, but in the present embodiment, it is easy to attach to the building, and the wire rod 1 can be attached easily and securely. A rectangular iron plate with a plate thickness of 3 mm was processed and used. That is, the support column 2 is an L-shaped member composed of a vertical portion 21 and a horizontal stop portion 22 as shown in FIG. 1, and a groove 21 a is formed around the upper end portion of the vertical portion 21 and the horizontal stop portion 22 is formed. Has a bolt hole 22a. In this embodiment, the distance h between the lowermost end of the horizontal stop 22 and the groove 21a is set to about 20 cm.

Then, in order to actually support the copper wire 1 on the column 2, the following procedure is performed. First, as shown in FIG. 2, the columns 2 are fixed to the building 3 so that the mutual distance L between the columns 2 is 3 m to 5 m. Next, the copper wire 1 is wound a plurality of times around the groove 21a formed in the vertical portion 21 of the pillar 2, and the copper wire 1 is sequentially locked to the pillar 2 so that the copper wire 1 is lifted from the building 3. Stretch around with.

Next, the installation location and installation method of the pigeon dropping prevention device A of this embodiment will be described. First, in a temple, as shown in FIGS. 3 (A) and 3 (B), the upper part a of the ridge, the eaves b of the roof on the second floor, the attic c on the second floor, the four corners d of the roof on the first floor, The copper wire 1 is laid over the peripheral part e of the upper end of the roof on the first floor by the method shown in FIG. At this time, if the fixing point of the supporting column 2 is a plate material, a nail or the like is driven into the bolt hole 22a formed in the supporting column 2 to fix the supporting column 2. Further, when the fixed portion of the support column 2 is a roof tile or the like, anchor bolts are driven into the bolt holes 22a formed in the support column 2 to fix the support column 2.

Further, in the bridge girder of the bridge, as shown in FIGS. 4 to 5, the copper wire 1 is quadrangled over the upper part of the bridge girder 4 by the method shown in FIG. At this time, since the fixing point of the column 2 is generally concrete, an anchor bolt is driven into the bolt hole 22a formed in the column 2 to fix the column 2.

Further, inside the warehouse or the like, as shown in FIGS. 6 to 7, the copper wire 1 is laid between the upper ends of the pillars 5 and the roof by the method shown in FIG. At this time, when the fixing point of the support column 2 is a plate material, a nail or the like is driven into the bolt hole 22a formed in the support column 2 to fix the support column 2. When the support 2 is fixed to an iron plate or the like, a bolt is passed through the bolt hole 22a formed in the support 2, and a nut is tightened or a steel plate text screw is used to fix the support. Further, when the fixing point of the support column 2 is a thick steel plate, it is fixed by welding.

Further, in the warehouse / roof of a relatively large house, as shown in FIG. 8, the copper wire 1 is laid over the upper part 1 of the ridge, the eaves m and the gab part n by the method shown in FIG. At this time, when the fixing point of the support column 2 is a plate material, a nail or the like is driven into the bolt hole 22a formed in the support column 2 to fix the support column 2. Further, when the fixed portion of the support column 2 is a roof tile or the like, anchor bolts are driven into the bolt holes 22a formed in the support column 2 to fix the support column 2. Moreover, when the eaves back o is deep, it is preferable to bridge the copper wire 1 also on the eaves back o.

If the width of the mounting portion of the support column 2 is 20 to 30 cm, the support column 2 may be fixed to the center and one copper wire 1 may be stretched along the support column 2, but the mounting location If the width is large, it is preferable to stretch a plurality of copper wires 1, and as a standard, the distance between the plurality of copper wires 1 may be about 30 cm.

Since it is empirically known that pigeons flock very well at all of the above locations, if the copper wire 1 is laid over the location, the copper wire 1 will be 20 # (diameter 0.8 mm), so the pigeon cannot stop on its copper wire 1. Also, when the pigeon flapping its wings trying to land near the area where the copper wire 1 is spanned, the wings come into contact with the copper wire 1, and therefore it is not possible to land near the lower portion where the copper wire 1 is stretched. In other words, the pigeon will not approach the building at all because the copper wire 1 is stretched over the desired location and cannot be approached. Therefore, it is possible to protect the building and the like from the damage of pigeon droppings.

[0019]

[Effect of device]

 With the pigeon droppings prevention device of the present invention, the pigeon cannot stop on the wire rod and cannot land near the lower portion of the wire rod, so the pigeon does not approach the place where the wire rod is stretched. Therefore, it is possible to protect the building and the like from the damage of pigeon droppings.
