Description

  The present invention relates to an avian repellent device that uses birds 'habits and body structure and prevents damage caused by droppings of birds and birds' crying by installing them in places where birds do not want to stop.

  Traditionally, birds such as pigeons stop flying on public transportation such as railways, airfields, or external structures of public facilities, and they are polluted by dropping feces on the clothes and hair of passers-by. Has occurred. In addition, the crowing sounds of birds make noise, which is annoying to the users who use the public institutions to go near the birds.

  As countermeasures, various instruments have been devised and put into practical use in order to avoid the effects on agricultural products and the invasion of apartment houses on the veranda.

  Farmers, for example, still use birds-preventing equipment that prints patterns on balloons and resin discs, highlighting the eyes of raptors, and shines brightly by reflecting sunlight. Further, for example, Japanese Utility Model Laid-Open No. 4-80379 discloses a means for preventing birds from approaching by applying a teg string by utilizing the property that birds dislike foreign matter coming into contact with the wings or being difficult to see. .

  However, these means cannot quickly cope with the following problems because birds become accustomed immediately.

  For example, in urban areas, there is a problem that pigeons gather on the veranda and clothes line of apartment houses, dropping and dropping feces and feathers on the spot. Similarly, there are many problems that pigeons nest on an electric bulletin board or destination sign board on a platform where passengers of public transportation are gathered, or stop and drop feces from above.

  Therefore, in order to deal with these problems, a means for birds such as pigeons to dislike strange things or to disrupt the sense of direction with magnetism is disclosed in Utility Model Registration No. 30430902, It makes it difficult for birds to get close.

  However, birds certainly use geomagnetism, but they also use vision and solar compass, so it has been found that as long as they can be used, they do not affect the sense of direction. See sub-team report). Therefore, it is considered difficult to prevent birds from approaching with magnets alone.

  Similarly, a method of applying, spraying, or spraying a medicine that smells, tastes or feels that birds dislike is also being carried out, but it can be easily inferred that the medicine will eventually flow with water or the like and the effect will be dilute.

  Therefore, as another measure, means having a structure that does not stop well when birds try to stop is disclosed in Japanese Utility Model Publication No. 60-36084 (rotary shaft in which a number of perches made of rod-shaped protrusions are arranged in the longitudinal direction) Japanese Unexamined Patent Publication No. 60-49784 (a mandrel through which a rotating body arranged in a bead shape passes).

Further, these means are further improved in appearance and simplified in structure, for example, disclosed in Japanese Utility Model Laid-Open No. 4-103484 and Japanese Utility Model Laid-Open No. 5-20582, and the flying bird tries to stop with peace of mind. If you ride on the device, the birds will suddenly lose balance and become unstable, so they can learn the dangers and not fly again.
Japanese Utility Model Publication No. 4-80379 Utility Model Registration No. 3043902 Japanese Utility Model Publication No. 60-36084 Japanese Utility Model Publication No. 60-49784 Japanese Utility Model Publication No. 4-103484 Japanese Utility Model Publication No. 5-20582

  However, the means disclosed in Japanese Utility Model Laid-Open No. 4-103484, Japanese Utility Model Laid-Open No. 5-20582, etc. were manufactured according to the drawings of the application specification and actually tested with a pigeon. It was found that it was easy to balance and rest on the rotating body.

  Also, even in the experiment using a thin metal plate with a thickness of about 0.5 mm, it was found that even at the end face, the bird balances with the tail and whole body dexterously.

  That is, as shown in FIG. 11, the rotating body 100 disclosed in Japanese Utility Model Laid-Open No. 4-103484, Japanese Utility Model Laid-Open No. 5-20582 and the like described above has a uniform surface, and this surface is uniform. When trying to stop at the rotating body 100, the birds 101 approach the rotating body 100 with their toes opened in advance (FIG. 11A).

  Thereafter, the birds 101 ride on the surface of the rotating body 100 with their toes open (FIG. 11B), and the gravity G acting on the birds 101 passes through the center of gravity C of the rotating body 100 so that the tail And the whole body is balanced and the movement is stopped.

  The state of the legs L and legs F of the birds in this case is as shown in FIG. 10 (see page 140 of the field observation pictorial book 5 “Birds” published by Keibunsha Co., Ltd. 2003).

  That is, in FIG. 10, if the upper part from the heel N is the leg L and the lower part from the heel N is the foot F, the tendon K on the back of the foot F is connected to the muscle M, and the other is the toe A1. , A2, A3, A4.

  When the birds are standing or walking, the heel N is raised and the toes are standing, as shown in the figure. At this time, the tendon K is loose and the fingers A1 to A4 of the foot F are opened. Yes.

  Then, as shown in FIG. 11 (B), when the bird 101 is performing a motion of being balanced and stationary, as described above, the toes A1 (FIG. 10), A2, A3, A4 Is open, at which time the tendon K is loose.

  Therefore, as shown in FIG. 11 (B), as long as the bird G performs a stationary operation with a balance between the tail and the whole body so that the gravity G acting on the bird 101 passes through the center of gravity C of the rotating body 100, Technology is ineffective.

  In other words, as long as the bird 101 can stand or walk with the fingers A1, A2, A3, and A4 (FIG. 10) of the foot F open, the conventional technique (see Japanese Utility Model Laid-Open No. 4-103484 and Japanese Utility Model Application 5- (Means disclosed in Japanese Patent No. 20582) No matter how much the rotating body is supported by a bearing having high lubricity, the birds ride on the balance and stand still.

  For this reason, damages such as dropping of feces while birds are on the rotating body occur, and conventional techniques (such as the above-mentioned Japanese Utility Model Publication No. 4-103484) are ineffective.

  In short, the operation shown in FIG. 11 (B) in which the bird 101 balances with the tail and the whole body so that the gravity G acting on the bird 101 passes through the center of gravity C of the rotating body 100, and the bird 101 has the foot F. The posture shown in FIG. 10 where the fingers A1 to A4 can stand and walk with the fingers A1 to A4 open is in a one-to-one correspondence, and the two are inseparable.

  Therefore, as long as the posture shown in FIG. 10 is possible, the birds 101 (FIG. 11B) are balanced on the rotating body 100 and are stationary, and as described above, the prior art has no effect.

  Therefore, the inventor of the present application does not allow the bird to get on the rotating body and take a balanced and stationary motion (FIG. 11B), in other words, the bird can move its toes A1 (FIG. 10). ) Birds bend the leg L (see page 140 of Chapter 5 “Birds” in the Field Observation Book 5 published by Sobunsha Co., Ltd., 2003) so that A2, A3, A4 cannot be opened and walked. In order to solve the above-mentioned problem, pay attention to the means of tightening the tendon K, closing the fingers A1, A2, A3, A4 of the foot F and grasping the tree branch B, etc. As described in Item 1, there is provided a bird repelling device comprising a rotating body 4 (FIG. 1) made of a bar and a protrusion 5 provided on the rotating body 4.

  In this case, the rotating body 4 is rotatably supported by attachment members 2 and 3 provided at both ends in the longitudinal direction, and the protrusion 5 extends over the entire longitudinal direction (X-axis direction) of the rotating body 4. A plurality of protrusions 5 (FIGS. 2 and 3), and among the plurality of protrusions 5, there is a surface 11 on which the bird 1 can stop between adjacent protrusions 5; In some cases, such a surface 11 does not exist, and when the surface 11 exists (for example, FIG. 4), the width Q of the surface 11 is the width P of the fingers A1 to A4 of the legs F opened by birds (FIG. 10). 11 (B)), the rotary body 4 and the protrusion 5 are laterally symmetric, with the former being square or round and the latter being square, round or fan-shaped.

  According to the configuration of the present invention described above, the bird 1 (FIG. 9A) approaches the rotating body 4 with the toe open and puts the protrusion 5 provided on the rotating body 4 over the weight. First, the fingers A1, A2, A3, A4 of the foot F are brought into contact with the protrusion 5 (FIG. 9B), and then the legs A1 to A4 of the foot F are placed on the protrusion 5 while being put on the leg. When the portion L is bent, the tendon K (FIG. 8) is stretched and the finger begins to close (FIG. 9C), and when the leg L is further bent (FIG. 9D), the tendon K is further stretched and the fingers A1 to A1. A4 is completely closed and grips the protrusion 5. At this time, a force R is applied from the birds 1 side to the rotating body 4 side to generate a moment R and try to rotate the rotating body 4. As shown in FIG. 10, gravity G acting on the birds 1 (FIG. 9E) passes through the center of gravity C of the rotating body 4 so that the tail and the whole body are balanced and stationary. As shown in FIG. 8, the legs 1 try to open the fingers A1 to A4 of the foot F by extending the leg L and loosening the tendon K, but the birds 1 are grasping the protrusion 5, and as shown in FIG. 10 is closed and the fingers A1 to A4 of the foot F are closed and the protrusions 5 are gripped, so that the posture of FIG. 10 cannot be taken simultaneously with FIG. However, the bird 1 cannot rotate the stool while remaining on the rotating body 4, thereby preventing the damage that has occurred in the past.

  As described above, according to the present invention, the bird's habits and the structure of the body are used, and it is installed in a place where the birds do not want to stop to prevent harm caused by the droppings of birds or the noise of birds. The effect is to provide a bird repelling device.

  FIG. 1 is an overall view of a bird repelling apparatus according to the present invention. In FIG. 1, reference numeral 1 is a bird such as a pigeon, 2 is a mounting member, 4 is a rotating body, and 5 is a protrusion.

  The rotating body 4 is made of a bar material that is long in the X-axis direction, and the rotating shaft 6 passes through the center of the rotating body 4. The rotating shaft 6 extends outward from both ends of the rotating body 4, and the portions extending outward are rotatably supported by the attachment members 2 and 3.

  The mounting members 2 and 3 have the same shape. For example, the mounting member 3 (FIG. 2) has a substantially cubic shape, and the rotating shaft 6 is supported by a bearing in the mounting member 3. . That is, an inner ring 7 and an outer ring 8 are arranged on the mounting member 3 (FIG. 2), and an outer bearing 9 and an inner bearing 10 (FIG. 3) are inserted between the inner ring 7 and the inner ring 7. The rotating shaft 6 described above is attached. The same applies to the other mounting member 2 (FIG. 1).

  The cross-sectional shape of the rotating body 4 includes various shapes such as a square shape (for example, FIG. 5A) and a round shape (for example, FIG. 5B), but the left and right (Y-axis direction) are symmetrical, It is preferable that it is easy to rotate.

  Among them, a representative example of a square is, for example, a regular square (FIG. 4), and projections 5 are provided corresponding to the vertices a, b, c, and d of the regular square. (FIG. 9) It is grasped with fingers A1, A2, A3, A4 of the foot F.

  Each of the apexes a, b, c, and d is provided with a substantially triangular projection 5 via a connecting portion 5B, and each projection 5 is formed with a hollow portion 5A to reduce the weight. This protrusion 5 is provided over the entire longitudinal direction (X-axis direction).

  If the protrusion 5 is not halfway in the longitudinal direction (X-axis direction) but is interrupted (FIG. 1), for example, when the cross-sectional shape of the rotating body 4 is circular (FIG. 5B), The interrupted portion is in the same state as the rotating body 100 (FIG. 11A) having a uniform surface as before, and the gravity G acting on the birds 101 passes through the center of gravity C of the rotating body 100 as described above. As described above, the bird 101 is balanced with the tail and the whole body (FIG. 11B), and the bird 101 stops there and drops feces and the like, causing harm to passers-by.

  Therefore, as described above, by providing the projection 5 over the entire length direction (X-axis direction) (FIG. 1) so that the bird 101 cannot perform such a movement, the fingers A1 to A4 of the foot F are always held. (FIG. 9) Closed and grasped.

  In addition, the cross-sectional shape of the rotating body 4 includes a regular triangle (FIG. 6A), a regular pentagon (FIG. 6B), a regular hexagon (FIG. 6C), etc. (Y-axis direction) is symmetrical. Also in this case, the protrusion 5 is provided over the entire longitudinal direction (X-axis direction) (FIG. 1).

  On the other hand, a plurality of protrusions 5 are provided (FIGS. 4 to 6), and the width Q (FIG. 4) of the surface 11 between the adjacent protrusions 5 is the width P of the fingers A1 to A4 of the open legs F of birds. It is smaller than (FIG. 10, FIG. 11 (B)).

  If the width Q (FIG. 4) of the surface 11 between the adjacent protrusions 5 is larger than the width P (FIG. 10, FIG. 11 (B)) of the fingers A1 to A4 of the open legs F of birds. The bird stands on the surface 11 (FIG. 4) with the fingers A1 to A4 of the foot F open.

  As a result, as usual (FIG. 11 (B)), the birds 101 are stationary and balanced between the tail and the whole body so that the gravity G acting on the birds 101 passes through the center of gravity C of the rotating body 100 (FIG. 11 ( B)), the bird 101 stops there and drops feces and the like, causing harm to passersby.

  Therefore, as described above, the width Q (FIG. 4) of the surface 11 between the adjacent protrusions 5 is greater than the width P (FIGS. 10 and 11 (B)) of the fingers A1 to A4 of the open legs F of birds. Is also small.

  This condition is necessary because, as shown in FIGS. 5A, 5B, and 6A to 6C, the adjacent protrusions 5 are discontinuous, and the surface 11 exists. As shown in FIG. 5C, when the adjacent projections 5 are so-called continuous and the surface 11 does not exist, the above condition is not necessary.

  That is, in the case of FIG. 5C, there is no surface 11 (for example, FIG. 5A) on which the birds can stop between the adjacent protrusions 5, in other words, the birds hardly stop.

  Therefore, in the case of FIG. 5C, the bird G stands up or walks with the fingers A1 to A4 of the foot F open (FIGS. 10 and 11B), and the gravity G acting on the birds is a rotating body. Birds do not balance with the tail and the whole body so as to pass through the center of gravity C of 100, and birds do not stop there and drop their shit and do not harm passers-by.

  Therefore, when the adjacent protrusions 5 are continuous as shown in FIG. 5C, the width Q (FIG. 4) of the surface 11 between the adjacent protrusions 5 is determined by the fingers A1 to A1 of the open legs F of the birds. The condition that the width is smaller than the width P of A4 (FIGS. 10 and 11B) is not necessary.

  Further, as shown in FIG. 7, the number of fingers A1 to A4 of the bird's foot F is generally four, and when grasping the protrusion 5, it is divided into three front and one rear (FIG. 7A). ), Two front and two rear (FIG. 7B), and all fingers A1 to A4 are facing forward (FIG. 7C).

  If all the fingers A1 to A4 of the birds are forward-facing, that is, only in the case of FIG. 7C, the cross-sectional shape of the protrusion 5 is asymmetric even if the left and right (Y-axis direction) are asymmetric. Birds can grasp the projection 5 with the fingers A1 to A4 of the foot F.

  However, as described with reference to FIG. 7, there are various types of birds for separating the toes A1 to A4 of the foot F, and it is unclear what kind of birds will fly.

  Therefore, the lateral cross-sectional shape of the protrusion 5 is preferably symmetrical in the left and right (Y-axis direction) so that the way of dividing the fingers A1 to A4 of the foot F can correspond to any bird (FIGS. 5 to 5). 6).

  That is, as the cross-sectional shape of the protrusion 5, a square shape such as a substantially triangular shape (FIG. 5A, FIG. 6A to FIG. 6C), a round shape such as a substantially circular shape (FIG. 5B), Alternatively, there is a fan shape (FIG. 5C), and both are symmetrical in the left and right (Y-axis direction).

  The operation of the present invention having the above configuration will be described below with reference to FIG.

  The structure of the bird body shown in FIG. 8 used when the operation of FIG. 9 is performed will be described in detail.

  In other words, there is a tendon K on the back of the bird's foot F, and this tendon K is connected to the muscle M and also to the fingers A1 to A4. As shown in FIG. 10), the tendon K is loose and the fingers A1 to A4 are also open.

  However, as shown in FIG. 8, when the leg L is bent and the tendon K is tightened, the fingers A1 to A4 of the foot F are also closed and the tree branch B and the like are firmly grasped. The present invention utilizes such a bird's body structure.

  Birds 1 (FIG. 9A) approach the rotating body 4 with their toes open, try to grab the protrusions 5 provided on the rotating body 4 over their weights, A1, A2, A3, and A4 are brought into contact with the protrusion 5 (FIG. 9B), and then the leg L is bent while the fingers A1 to A4 of the foot F are placed on the protrusion 5 (FIG. 9C )).

  When the bird 1 bends the leg L, as explained in FIG. 8, the tendon K is stretched and the finger begins to close (FIG. 9C), and the leg L is further bent (FIG. 9D). The tendon K is further stretched and the fingers A1 to A4 are completely closed to grasp the protrusion 5, but at this time, a force R is generated from the birds 1 side to the rotating body 4 side, and a moment R is generated to try to rotate the rotating body 4. In order to prevent this, the gravity G acting on the birds 1 as in the past (FIG. 9 (E)) is to balance the tail and the whole body so as to pass through the center of gravity C of the rotating body 4 so as to perform a stationary operation. As shown in FIG. 10, by extending the leg L and loosening the tendon K, the fingers A1 to A4 of the foot F are to be opened.

  However, as described above, the birds 1 are grasping the protrusion 5, and as shown in FIG. 8, the leg L is bent and the tendon K is stretched to close the fingers A 1 to A 4 of the foot F and grasp the protrusion 5. It is in posture.

  Therefore, the birds 1 cannot take the posture of FIG. 10 at the same time as FIG. 8, and therefore cannot perform a balanced and stationary operation, and as shown in FIG. Birds 1 cannot drop stool while staying on the rotating body 4, and the conventional harm is prevented.

  INDUSTRIAL APPLICABILITY The present invention is used for an avian repellent device that uses birds' habits and body structure and prevents damage caused by droppings of birds and bird calls by installing them in places where birds do not want to stop. When a bird such as a pigeon flies and stops at a station name signboard installed in a railway station building, which is a public transportation system, pollution such as dropping and dropping feces on the clothes and hair of passers-by underneath Blocked and extremely effective.
