[Prior art]

 2. Description of the Related Art Conventionally, there has been known a device which is installed on a veranda, a balcony, a handrail or the like of a condominium, a building or the like to prevent invasion of birds, especially pigeons (for example, Japanese Patent Publication No. 3-69253). The applicant also proposed a bird repellent device in which a pair of columns are erected on the handrail, wires are stretched between the columns, and a magnetic material is provided on the wires (Japanese Patent Application No. 4-93897).

[0003]

[Problems to be solved by the device]

 All of these are effective in preventing the pigeons from stopping on the handrails, but many intrusion prevention devices had to be installed when the veranda was large. It was also not always effective against birds trying to enter directly through the window. Therefore, a method of fixing and attaching a net etc. to the whole building opening such as a veranda could be considered, but there was a risk that the net would be obstructed in the event of an emergency such as a fire, and the activities of firefighters could be disturbed. In view of the above, it is an object of the present invention to provide a bird invasion prevention device that can prevent birds from invading a veranda or the like and that can be easily removed in an emergency such as a fire and that does not interfere with fire fighting activities.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an embodiment of a bird invasion prevention device according to the present invention, FIG. 2 is an enlarged vertical sectional view of an essential part of FIG. 1, and FIG. 3 is a front view showing a use state.

In these drawings, 1 is a first base member, 2 is a wire rod such as a plurality of wires suspended vertically from the base member 1 at appropriate intervals, and 3 is a wire member of the wire 2. The second base member 4, which is attached to the other end side and is elongated in the horizontal direction, is a wire attaching / detaching mechanism for attaching / detaching a part or all of the wire 2 to / from the second base member 3. The first base member 1 is longitudinally attached to the ceiling 7 (Fig. 3) of the building 5 such as a veranda by a screw or the like, and one end of which is fixed to the first base member 1. The wires 2 are suspended in parallel at appropriate intervals so that birds do not enter the opening 6. Also, the distance between the wires 2 depends on the type of bird, but for pigeons, about 5-10 cm is preferable. Further, the length of the wire 2 is set to a height from the ceiling 7 of the veranda to the handrail 8 so as to cover the open rear portion without a gap, as shown in FIG.

In the illustrated example, the second base member 3 is provided on the lower end side of the wire 2, and a plurality of holes 3 a are formed to penetrate the wire 2, and the wire 2 is also aerated by wind or the like. The weight is combined so that it may not exist. Although the wire attaching / detaching mechanism 4 is optional, in the case of the figure, a chuck 9 for passing the wire 2 through is provided in the second base member 3, and is located below the chuck 9 and upward so as to hold the chuck. It consists of a spring 10 for urging the spring 10 and a holding pin 11 for releasing the wire 2 when the chuck 9 is split into two when pressed against the spring 10. Therefore, when the pressing pin 11 is pressed against the spring 10, the chuck 9 opens and becomes loose, so that the wire 2 can slide in the vertical direction. When the pressing pin 11 is released, the spring 9 closes the chuck 9 to bite the wire 2 and fix it.

Therefore, in order to remove all the wires 2 from the second base member 3, it is sufficient to press the holding pin 11 of each wire, but it takes too much time in an emergency such as a fire. Further, a pressing plate member 12 may be provided so that each pressing pin 11 can be pressed at once. By pressing the plate member 12 downward with a hand or a foot, the pressing pin 11 can be pressed at once, and the wire 2 can be removed all at once. In this case, if the second base member 3 is detached from the wire and it falls and is dangerous, the length of the pressing plate member 12 is adjusted as shown in the figure so that the pressing pins 11 on both ends of the wire are contacted. The length should not touch. Reference numeral 13 is a magnetic sphere, and in general, a bird has a property that it dislikes a strong magnetism that disturbs the biomagnetism (which determines the flight direction and is a sign of homing) that the bird itself has, so the wire 2 The wires are attached to every few wires at approximately the same height as shown in the figure, but they may be attached to all the wires. In this case, it is advisable to change the mounting height so that the magnetic balls do not attract each other.

In a conventional building or the like, an outdoor unit 14 of an air conditioner may be installed on a veranda as shown in FIG. In this case, birds are likely to gather due to the heat of the outdoor unit 14, and in some cases a nest may be formed on the veranda. For this reason, the balcony was polluted with feces and it was unsanitary. However, if the intrusion prevention device of the present invention is used, the opening 6 of the veranda or the like is completely covered with the wire, so that it is possible to prevent birds from entering the veranda. In particular, since the wire 2 is positioned vertically rather than horizontally, the bird does not stop by grasping the wire. In addition, in the event of an emergency such as a fire, the wire 2 can be easily removed from the first base member 3, and it is easy to evacuate the room or invade a room such as a firefighter. Further, the magnet 13 can prevent not only bird's invasion but also approaching, and does not damage the bird, which is extremely practical. In the figure, reference numeral 15 is a room, 16 is a doorway between the room 15 and the balcony, and 17 is a floor.

Next, a second embodiment of the bird intrusion prevention device of the present invention will be described with reference to FIGS. 4 to 6. 4 is a front view showing a second embodiment of the present invention, FIG. 5 is an enlarged view showing the curtain mechanism of FIG. 4, and FIG. 6 is a side sectional view taken along the line AA of FIG. In the second embodiment, the same members as those of the first embodiment are designated by the same reference numerals.

In this embodiment, a curtain mechanism 18 is used in place of the wire attaching / detaching mechanism 4, and a plurality of hooks 21 are slidably attached along a rail 20 in a casing 19, and the hooks 21 are slidably attached. The wire 2 is hung on each of 21. In addition, the wires 2 are supported by a flexible support member 22 with their upper ends bent so that the wires 2 are opened at appropriate intervals in the horizontal direction. The structure of the curtain mechanism 18 (casing 19, rail 20, hook 21) is similar to that of a general indoor curtain mechanism. A base member 23 also serving as a weight and a magnetic ball 13 are provided below the wire 2 so as to prevent the wire 2 from being hit by wind or the like, as in the above embodiment.

Therefore, in the second embodiment as well, the opening 6 of the veranda or the like is completely closed by the wire, so that it is possible to prevent a bird from entering the veranda and to prevent a fire. In the event of an emergency such as by shifting the wire 2 to the left or right as shown in FIG. 7, it is possible to evacuate from the space to the outside or enter the room such as firefighters. Further, the magnet 13 can prevent not only birds from entering but also approaching birds.

[Effect of device]

 INDUSTRIAL APPLICABILITY As described above, the present invention comprises a horizontally elongated upper base portion that is attached along the ceiling of a veranda, a plurality of wires that are suspended from the upper base portion in the horizontal direction at appropriate intervals, and Since it has a horizontally elongated lower base that is attached below the plurality of wires and also serves as a weight, and a wire attaching / detaching mechanism that attaches / detaches the plurality of wires and the lower base, the wires completely block the veranda. Therefore, it is possible to prevent birds from entering the veranda. In addition, the wire can be easily removed from the base member in the event of a fire or when drying clothes. Even if a curtain mechanism is provided instead of the wire attachment / detachment mechanism, the wire can completely block the veranda and prevent birds from entering the veranda as in the previous case, and the wire can be displaced when a fire occurs. There is an advantage that people can come and go. Further, since the magnetic body is provided below the wire, there is an effect that the bird cannot be brought close to it.
