Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird stopping device for preventing birds such as pigeons from stopping on the upper surface of a structure such as a window stand.

[0002]

2. Description of the Related Art For example, a bird such as a pigeon may fly into a building which is a structure and stop on a window sill, an eaves, or an upper surface of a handrail of a veranda or the like.

[0003]

By the way, if the bird is allowed to stop on the upper surface of the structure, a large amount of feces may be accumulated on the upper surface, and in this case, the appearance of the structure is remarkable. There is a risk of damage and it is also unsanitary.

[0004]

SUMMARY OF THE INVENTION The present invention has been made by paying attention to the above circumstances, and prevents birds from stopping on the upper surface of the construct to keep the appearance of the construct in good condition. The purpose is to prevent the sanitary problems caused by the feces of.

[0005]

[Means for Solving the Problems] To prevent the above problem, a bird's stop prevention device of the present invention comprises a plurality of wire rods which are spaced apart from a top surface of a structure by a predetermined distance and are stretched along the top surface. The wire rods are arranged substantially parallel to each other at a predetermined distance from each other in plan view.

In the above case, each wire may be detachable from the structure.

[0007]

[Operation] The operation of the above configuration is as follows.

The bird stop prevention device 8 is constructed with the constructions 1, 19, 2
A plurality of wire rods 15 are provided so as to be spaced apart from the upper face 6 of the upper part 2 by a predetermined distance H and stretched along the upper face 6 of the same.
5 are provided substantially parallel to each other at a predetermined distance W from a plan view.

Therefore, when the bird 7 tries to enter between the upper surface 6 and the wire rod 15, the wire rod 15 interferes with the operation of the bird 7 to prevent the bird 7 from entering.

Further, the bird 7 has its foot 7a adjacent to the wire 1
When it tries to stop on the upper surface 6 by passing between 5, 5 and 15, the body 7b of the bird 7 contacts the wire 15 before the foot 7a contacts the upper surface 6, and the bird 7 moves the upper surface 6 Stopping on top is prevented.

On the other hand, it is assumed that the bird 7 stops on the wire 15 as shown by the phantom line in FIG.

Then, since the wires 15 are separated from each other by a predetermined distance W in a plan view, the bird 7 has its foot 7a.
Cannot be stopped by straddling a large number of wire rods 15, and the posture for stopping is unstable.

Moreover, the wire 1 which is loaded by the bird 7
In No. 5, the posture for stopping cannot be fixed because it flexes or shakes according to the magnitude of the load, and therefore the posture for stopping always becomes extremely unstable. However, the bird 7 is prevented from stopping on the upper surface 6.

In the above case, each wire 15 may be attachable / detachable to / from the structures 1, 19, 22.

In this way, the constructs 1, 19, 22

In FIG. 2, reference numeral 1 is a building which is a building, and a side wall 2 of the building 1 has a window opening 3 formed therein. A sliding glass window 4 for opening and closing the window opening 3 is provided.

A lower opening edge of the window opening 3 on the outdoor side is a window stand 5, and an upper surface 6 of the window stand 5 faces the outside.
I'm leaning down. A bird stop prevention tool 8 is provided on the upper surface 6 of the window stand 5 to prevent birds 7 such as pigeons from stopping.

In FIGS. 1 to 4, the above-mentioned bird stop prevention tool 8 means the left and right directions (directions toward FIGS. 1, 2 and 3).
The same applies to the following). Each of these mounting bases 10 is formed of an angle made of aluminum, each mounting base 10 extends substantially horizontally, and is attached to and detached from each of the left and right side walls 11 at the opening edge of the window opening 3 by a pair of anchor bolts 12, 12. It is fixed freely.

Between the left and right mounts 10 and 10, a plurality of (4
The wire 15) is stretched without slack and with a slight tensile force applied. Each of these wire members 15 is spaced apart from the upper surface 6 in the vertical direction by a predetermined distance H, and extends left and right along the upper surface 6. Further, the respective wire members 15 have a predetermined distance W from each other in the width direction, particularly in a plan view shown in FIG.
Adjacent wire rods 1 that are spaced apart and substantially parallel to each other
Reference numerals 5 and 15 are located substantially horizontally to each other.

In the above case, the wire 15 is made of one elastic stainless wire having a diameter of 1 to 3 mm (preferably about 2 mm) as the material 16. This material 16 is used in the following manner for each of the mounting bases 10 described above. Is attached to.

That is, four through holes 17 are formed in each of the mounting bases 10 at equal intervals, and the material 16 is inserted into the through holes 17 in a left-right zigzag shape. Further, each end 15a of the wire 15 is tied to the mounting base 10 on the right side, and thus the plurality of wires 15 are formed. The wire 15 can be easily removed from each of the mounting bases 10 by unfastening each of the end portions 15a bound to the mounting bases 10.

The above-mentioned predetermined vertical spacing H is such that when the bird 7 tries to enter the upper surface 6, each wire 15
Has a dimension that interferes with the movement of the bird 7 and prevents it from entering, and is about 60 mm or less. Further, when the bird 7 tries to stop on the upper surface 6 by passing its foot 7a between the adjacent wire rods 15, 15, the body 7b of the bird 7 contacts the wire rod 15 prior to this contact. The dimension of the predetermined interval H is determined. From this point of view, the predetermined distance H is about 30 mm or more.

On the other hand, the predetermined width W in the width direction is such that when the bird 7 tries to stop on the wire 15, the foot 7a is in contact with at least one wire 15 and the upper foot 7a is 3
Approximately 20 to 80, which does not straddle one or more wires 15.
mm (preferably 40 to 70 mm).

When the bird 7 tries to enter between the upper surface 6 and the wire rod 15, the wire rod 15 prevents the entry as described above.

Also, the bird 7 has its foot 7a adjacent to the wire rod 1
When it tries to stop on the upper surface 6 by passing between 5, 5 and 15, the body 7b of the bird 7 contacts the wire 15 before the foot 7a contacts the upper surface 6, and the bird 7 moves the upper surface 6 Stopping on top is prevented.

On the other hand, it is assumed that the bird 7 stops on the wire 15 as shown by the phantom line in FIG.

Then, since the wires 15 are separated from each other by a predetermined distance W in a plan view, the bird 7 has its foot 7a.
Cannot be stopped by straddling a large number of wire rods 15, and this stopping posture becomes unstable.

Moreover, the wire 1 which is loaded by the bird 7
5 is elastically bent or swayed in accordance with the magnitude of the load, so that the posture for stopping cannot be constant, and therefore the posture for stopping is always in an extremely unstable state. Become.

Therefore, also in this respect, the bird 7 is prevented from stopping on the upper surface 6.

Since each of the wires 15 is thin and difficult to see from a distance, the appearance of the bird's perimeter 8 will not hinder the appearance of the building 1. .

Further, as described above, the constructs 1, 19, 2
Since each wire 15 is detachable with respect to No. 2, when cleaning the upper surface 6 of the structure 1, 19, 22 or the like, when each wire 15 is in the way, remove it and clean the above. Good.

Although the above is based on the illustrated example, the structure may be a utility pole or the like. The wire 15 may be a wire or a coil spring having a small diameter. Further, the adjacent wires 15, 15 may be tilted downward toward the outside along the upper surface 6 of the window stand 5. The wire 15 may be stretched in a slightly loosened state.

[0046]

According to the present invention, the bird stop prevention device is
A plurality of wire rods are provided so as to be spaced apart from the upper surface of the structure by a predetermined distance and stretched along the upper surface of the same. The wire rods are arranged substantially parallel to each other at a predetermined distance in plan view.

Therefore, when the bird tries to enter between the upper surface and the wire rod, the wire rod interferes with the operation of the bird and the above bird is prevented from entering.

When the bird tries to stop on the upper surface by passing its foot between the adjacent wire rods, the body of the bird comes into contact with the wire rod before the foot comes into contact with the upper face, Are prevented from stopping on the upper surface.

On the other hand, it is assumed that the bird stops on the wire.

Then, since the wire rods are separated from each other by a predetermined distance in a plan view, the bird cannot stop by straddling its legs over a large number of wire rods, and the posture for stopping is unstable. Become.

Moreover, the wire rod loaded by the bird is
Since it bends or shakes according to the magnitude of the load, the posture for stopping cannot be fixed, and therefore,
The stopping posture is always extremely unstable, and in this respect also, the bird is prevented from stopping on the upper surface.

Since birds are prevented from stopping on the upper surface of the building as described above, a large amount of feces is prevented from accumulating on the upper surface.

Therefore, the appearance of the building can be kept good and the sanitary condition can be maintained.

Since each of the above wires is thin and difficult to see from a distance, the appearance of the building will not be obstructed even if the above-mentioned bird stop prevention device is provided. Keeps good.

In the above case, each wire may be detachable from the construct.

By doing so, when each wire rod is in the way, such as when cleaning the upper surface of the structure, it is sufficient to remove it, thereby facilitating the above cleaning and the like.
