Description

  This device improves bird repellents and bird repelling devices to prevent birds such as pigeons and crows from coming and approaching houses, stations, factories, and fields, and preventing various damages caused by these birds. In particular, the present invention relates to a bird-repellent body made of a permanent magnet that imparts directivity to generated magnetic field lines, and a bird-repelling device using the bird-repellent body.

  In recent years, bird nesting and fecal damage in houses, stations, factories and the like have become a problem. In addition to fouling roofs and verandas, bird stool mediates various pathogens and scatters fine powder of dried stool, causing respiratory diseases. In addition, damage to crops caused by birds is also significant. Therefore, in order to avoid the approach of birds and prevent various harms, various bird flying prevention devices have been proposed.

  Among them, birds that have biomagnets (magnetites) in their bodies are designed to prevent birds from flying by using the property of sensitively reacting to weak geomagnetic fluctuations and forming locally anomalous magnetic field. The device is known. For example, as shown in Patent Document 1, the present applicant also supports a device in which a large number of permanent magnets are supported at regular intervals on a yarn stretched through struts, and this is installed at a place where birds fly. We are developing. This type of device attempts to repel birds by the magnetic field generated by a permanent magnet.

Utility Model Registration No. 2558011

  However, many of these repelling devices support spherical or disk-shaped permanent magnets on the yarns at appropriate intervals, so that the formed magnetic field is formed on concentric circles centering on the permanent magnets. For this reason, in order to form a variable magnetic field in a wide range, it has been necessary to support magnets having a strong magnetic flux density at close intervals. Further, no ingenuity has been made on the appearance of the permanent magnet.

  In the present invention, in order to solve these problems in the prior art, the magnetic field lines generated from the magnets have directivity, and are particularly effective for birds flying from the sky. It is devised to visually threaten birds.

  In order to achieve the above-described object, the present invention provides a bird repellent, a hemisphere made of a permanent magnet, a steel ball provided in a contact state protruding from the center of the cut surface of the hemisphere, the cut surface and A means of constituting with a resin film covering a steel ball was adopted.

  And the said resin film employ | adopted the means that the place corresponding to the said steel ball is a transparent or semi-transparent resin film.

  In addition, the bird repelling device is composed of a plurality of the above-mentioned bird repelling bodies, a line connecting the respective bird repelling bodies, a plurality of struts supporting the line reeds, and a fixing plate for attaching each strut. The bird repelling body connected to the wire was installed between the columns.

  Further, at this time, the support column is provided with a thread groove on the upper end and the lower end, and provided with a vertical groove into which the wire can be inserted in the diameter direction of the upper end, and a retaining nut for clamping the wire on the upper end. Adopted the means that is screwed.

  Further, the fixing plate is composed of two plane plates parallel to each other at a predetermined interval, and a support plate that extends one step higher between the plates, and a support hole for screwing the support column is formed in the support plate. At the same time, the means that each flat plate was formed with a countersink was adopted.

  Also. A means of further providing an insertion hole on the side surface of the support plate of the fixed plate was adopted.

  In the bird repellent body having the above configuration, a steel ball attached to a hemisphere is magnetized by a permanent magnet, and magnetic field lines having a high magnetic flux density are concentrated and emitted from the upper end portion. Therefore, a high repellent effect for birds can be obtained in the upper surface direction of the hemisphere. In addition, since the resin film is transparent or translucent, the steel ball can be seen through, and the light is reflected on the metal surface and the appearance is observed like an eyeball. Can not be.

  In addition, since the bird repelling device having the above-described structure has a plurality of bird repelling bodies having the above-described structure installed between the support columns, an abnormally varying magnetic field is generated around each bird repelling body, and the birds do not approach over a wide range. . In particular, as described above, the magnetic lines of force are concentrated and released in the upper surface direction of each bird repellent body, so that the repellent effect on birds flying from above is high.

  The lower end of the column can be firmly fixed to the fixing plate by screwing. At the upper end, the wire can be pinched by a lock nut after the wire is inserted into the vertical groove, so that the wire is not damaged and the wire is not cut carelessly. .

  The fixing plate is fixed by screwing the support column into the support hole. By applying an adhesive to the lower surface of the flat plate, it can be fixed to a flat surface of various materials. It is also possible to fix with a screw or the like using a countersunk hole drilled in the flat plate. Furthermore, if both are used together, it can fix to a plane more firmly. Furthermore, by using a string or a binding band, it can be easily fixed to a bar such as a pipe. At this time, the string and the binding band can be fixed without being displaced by inserting and tightening the string or the binding band in the insertion hole provided on the side surface of the support plate, so that the string or the binding band is not accidentally dropped from the pipe or the like.

  Hereinafter, preferred embodiments of a bird repellent and a bird repellent device according to the present invention will be described with reference to the drawings. 1A is a sectional view of a bird repellent body, FIG. 1B is a plan view, and FIG. 1C is a perspective view. The bird repellent body is composed of a hemisphere 1, a steel ball 2, and a resin coating 3 as shown in the figure. The hemisphere 1 is made of a permanent magnet such as a ferrite magnet, for example, and is magnetized such that the cut surface 1a has an N pole and the top 1b has an S pole (or vice versa). The steel ball 2 protrudes to the center of the cut surface 1a of the hemisphere 1 and is attached in contact. Since the steel ball 2 is in close contact with the hemisphere 1 of the permanent magnet, the steel ball itself has magnetism under the influence of the permanent magnet, and magnetic field lines with high magnetic flux density are concentrated and emitted from the upper end 2a. Will be. Therefore, high-density magnetic field lines are emitted especially in the upper surface direction, and a high repellent effect is exhibited against birds. The resin coating 3 is made of a transparent or translucent material, and covers the cut surface 1a of the hemisphere 1 and the steel ball 2 to protect them. Therefore, the steel ball 2 can maintain a gloss for a long time. When this bird repellent is installed outdoors, the resin film is transparent, so the steel ball 2 reflects sunlight well, increasing the repellent effect on birds, and the steel ball penetrates through the center of the cut surface. It can be seen and its appearance looks like an eyeball as shown in FIG. As shown in FIG. 1 (c), this bird repellent body is constructed as a bird repellent apparatus by connecting a plurality of steel balls 2 with nylon tegs or the like and laying it on a roof or a veranda. be able to. In addition, it is also possible to arrange each bird repellent body as it is on the flat surface at an appropriate interval, and in that case, the same bird repellent effect is exhibited.

  Next, a bird repelling apparatus using the bird repellent will be described. FIG. 2 is an exploded perspective view of a part of the bird repelling apparatus according to the present invention. This bird repellent device includes a plurality of bird repellent bodies 11 and 11 described above, a line 12 made of nylon tegus or the like for connecting the bird repellent bodies 11 respectively, and a plurality of struts 13 that support the line 12, It is comprised from the fixing plate 14 which fixes each support | pillar 13. That is, the column 13 is attached to the fixed plate 14, and the fixed plate 14 is installed at a predetermined interval on a veranda or a roof. Specific means for installing the fixing plate 14 will be described later. Next, the bird repelling device is completed by fixing the wire 12 connecting the plurality of bird repelling bodies 11 to the upper end portion of the support 13 of the fixing plate 14 and laying the bird repelling body 11 in the air. As a result, an abnormally variable magnetic field is generated around each bird repellent body 11 so that the birds cannot feel it and approach it. In particular, since each bird repellent body 11 has a structure in which a steel ball protrudes and is attached to the cut surface of the hemisphere, many magnetic field lines are concentrated and released from the steel ball portion, and the repelling effect in the upper surface direction is high. Further, since the bird repellent body 11 is erected in the air, it swings irregularly due to wind or the like. As a result, the direction and size of the magnetic field lines to be emitted become irregular. It becomes easier to form and the repellent effect is higher. As in the case of a single unit, the appearance of each bird repellent body is eye-catching, so that it is possible to visually threaten birds.

  Then, the detail of each structural member of the said bird repellent apparatus is demonstrated. The structure of the bird repellent 11 is as described above. About the filament 12, although the nylon teg is used in the above example, it is not limited to this. As long as the bird repellent body 11 can be connected and installed, a steel wire, a piano wire, or the like may be used. However, since it is installed outdoors, it is preferable that it has excellent durability and does not cause rust.

  FIG. 3 shows one embodiment of the support column 13. The column 13 is formed by, for example, threading grooves on the upper end 15a and the lower end 15b of a stainless bar 15 having a predetermined length (about 12 cm). The lower end 15b is fixed to a support hole 14d of the fixing plate 14 described below with screws. The upper end 15a is provided with a longitudinal groove 15c in the diametrical direction so that the line 12 is depressed. Then, the locking nut 16 is screwed from the upper end 15 a so that the wire 12 is pinched by the bar 15 and the locking nut 16. With such a fixing means, the filament 12 is not damaged and the filament 12 is not inadvertently cut. As the stop nut, a wing nut or a round head nut as shown in the figure is used so that the filament can be securely fixed.

  FIG. 4 shows one embodiment of the fixed plate 14. In the figure, (a) is a plan view, (b) is a sectional view, (c) is a side view, and (d) is a perspective view. The fixing plate 14 is made of, for example, an aluminum plate or the like, and has a cross-sectional shape of Ω and has a support plate 14b straddled between the two flat plates 14a and 14a arranged in parallel at a predetermined interval. Countersunk holes 14c and 14c are formed in the center of each flat plate 14a. Further, a support hole 14d having a screw groove formed inside is formed in the center of the support plate 14b, and the screw groove of the lower end 15b of the support column 13 is screwed to support the support column 13. . Further, an insertion hole 14e is provided on a side surface of the support plate 14b so as to penetrate the support plate in the lateral direction. The countersunk holes 14c are not limited to one for each flat plate, and a plurality of countersunk holes 14c may be provided.

  Next, a method for fixing the fixing plate 14 will be described. This fixing plate 14 can be fixed regardless of the material and shape of the installation location. That is, the material can be fixed to wood, resin, metal, concrete, tile or the like. In addition to a flat surface, the shape can be fixed to a square bar or a round bar like a railing on a veranda.

  Specifically, when fixing to the flat surface (H), for example, as shown in FIG. 5A, an adhesive 17 corresponding to the material of the flat surface (H) is applied to the lower surface of the flat plate 14a, and the flat surface (H). Paste to and fix. In this case, if the adhesive 17 is applied excessively, the adhesive 17 leaks from the countersunk hole 14c and solidifies, so that it can be fixed more firmly. When the plane is wood or concrete, the countersunk hole 14c is used as shown in FIG. 5B, and it is fixed to the plane (H) using wood screws 18 or flat screws according to the material. You can also. Furthermore, if an adhesive and a screw are used in combination, the fixing plate 14 can be more firmly fixed.

  On the other hand, when fixing to rods such as square bars and round bars, strings made of various materials such as nylon and stainless steel, known binding bands (for example, “Unic Band”, “Insulok Tie” (trade name)), hose Use clamps. For example, FIG. 5 (c) shows an example in which the SUS band is fixed to the pipe (P) by a binding band 19 of a method of winding up with a ratchet gear or the like. At this time, the binding band 19 penetrates the support plate 14b. The fixing plate 14 can be securely fixed by inserting it through the provided insertion hole 14e, winding it around the pipe (P), and tightening and fixing it with the ratchet gear portion 19a.

  Alternatively, a hose clamp-like fixing tool in which a stainless steel band is tightened with a screw screw may be used. In addition, the fixing plate 14 is attached to a known saddle metal fitting that can be attached to pipes or a “pyrack” (trade name) that is a clip-like support metal fitting by an appropriate means, and is attached to a desired location. It is also possible to construct the bird repellent body 11.
