  By the way, bird droppings such as wild bird droppings or nesting are not limited to overhead wires such as electric wires, but are also the same for steel towers and other buildings. If the conventional rotary bird damage prevention device shown in the above cited references 1 and 2 is installed, the frictional resistance with the angle member increases, so there is a problem that even if the wild bird stops, it does not rotate smoothly. At the same time, there is a problem in that the angled material stretched obliquely cannot be fixed at a required position because the rotary bird damage prevention device is displaced downward due to its own weight.

Moreover, even in the stay prevention device shown in Patent Document 3, since the thin plate-like elastic engagement piece is only elastically engaged with the surface of the angle member, the load on the elastic engagement piece is large, The elastic engagement piece is easily deformed in a short period of time, and the elastic engagement piece formed of a plastic material is elastically deteriorated in a short period of time by ultraviolet rays.
In addition, since the width and thickness of the L-shaped angle members that make up the steel tower and the like are not constant, conventionally, in order to be able to fix them firmly, they are individually elastically matched to their width and thickness. There is a problem that it is necessary to design a piece, which increases the manufacturing cost.

  For this purpose, the bird damage prevention rotator support tool according to the present invention is composed of a pair of semicircular arc-shaped members in which a rail part on which the bird damage prevention rotator is rotatably supported is formed on the outer periphery. A V-shaped receiving portion having an opening angle of 90 degrees is integrally formed on the inner peripheral edge of the arc-shaped member, and the other semi-arc-shaped member has convex crimping portions facing the V-shaped receiving portion on both sides. By forming a curved arm-like highly elastic portion that is continuous with the inner peripheral edge of both ends of the arc-shaped member, the V-shaped receiving portion and the aforesaid are formed by integrally joining the pair of semi-arc-shaped members in an annular shape. An angle member having an L-shaped cross section is elastically sandwiched between the convex crimping portion.

  The bird damage prevention rotating body support tool according to the present invention can be easily attached to a building such as a steel tower made of an angle material having an L-shaped cross section and can be fixed so as not to be displaced for a long time. Further, even if there are some differences in the width and thickness of the angle member, it can be attached without any problem, so the cost can be reduced.

It becomes. On the outer peripheral edges of the semicircular arc member 10 and the semicircular arc member 20, concave groove-like rail portions 11 and 21 for rotatably supporting a bird harm prevention rotating body 40 described later are integrally formed. The connecting structure of the semicircular arc member 10 and the semicircular arc member 20 is formed by integrally forming the connecting pieces 12 on both side surfaces of one end of the semicircular arc member 10 and opening a through hole 13 at the tip of the connecting piece 12. At the same time, protrusions 22 are provided on both side surfaces of one end of the semicircular arc member 20, the protrusions 22 are loosely fitted into the through holes 13, and the semicircular arc member 10 and the semicircular arc member 20 are connected to the protrusions. It is connected so that it can be opened and closed with 22 as a fulcrum. On the other hand, an engagement piece 14 is formed on one side surface of the other end portion of the semicircular arc member 10, an engagement hole 15 is formed in the engagement piece 14, and one end surface of the other end portion of the semicircular arc member 20 is formed. A protrusion 23 is provided so that the protrusion 23 can be loosely fitted in the engagement hole 15 and is hooked to the support shaft 16 protruding from the other side of the other end of the semicircular arc member 10. The child member 18 is provided so as to be rotatable, and a protrusion 24 is provided on one side surface of the other end of the semicircular arc member 20 so that the hook-shaped knob member 18 can be engaged with the protrusion 24. ing.

  Further, by forming a pair of slant pieces 17a, 17b integrally adjacent to the inner peripheral edge of one semicircular arc member 10, an open angle α downwardly in FIG. The character receiving portion 17 is formed integrally. In addition, a convex crimping portion 25 having slope portions 25 a and 25 b facing the V-shaped receiving portion 17 is formed integrally with the other semicircular arc member 20. A flat surface portion 25c is formed between the slope portions 25a and 25b. The convex crimping part 25 is formed integrally with the semicircular arc member 20 by providing curved arm-like highly elastic parts 26a, 26b connected to the inner peripheral edges of both ends of the semicircular arc member 20 on both sides. The reinforcing ribs 19 are integrally formed in a series from the inner peripheral surface of the semicircular member 10 to the back surface of the V-shaped receiving portion 17, and the convex crimping portion is formed from the inner peripheral surface of the semicircular member 20. 25 and the reinforcing ribs 27 are integrally formed over the back surfaces of the high elastic portions 26a and 26b. By molding these reinforcing ribs 19 and 27, the rigidity and strength of the V-shaped receiving part 17 and the highly elastic parts 26a and 26b are increased.

  The semi-arc-shaped member 10 and the semi-arc-shaped member 20 configured as described above are annularly aligned by engaging the protrusion 23 with the engagement hole 15 and engaging the hook-shaped knob member 18 with the protrusion 24. Worn. And, as shown in FIGS. 5 and 6 and indicated by a two-dot chain line in FIG. 2, the building such as a steel tower is constituted by the V-shaped receiving part 17 and the convex crimping part 25 at the time of fitting. An angle member 30 having an L-shaped cross section is elastically sandwiched. Thereby, the support tool according to the present invention is fixed to the angle member 30 in a stationary manner.

A bird damage prevention rotating body 40 as shown in FIG. 4 is rotatably provided on the outer periphery of the support tool fixed to the angle member 30 in this way. In the bird damage prevention rotating body 40, semicircular arc-shaped split rings 42 and 43 are provided at both ends of a plurality of rod-shaped bodies 41, and the split rings 42 and 43 are connected at one end so as to be opened and closed. The hook-shaped knob member 45 provided at one end of one split ring 42 can be engaged with a protrusion 46 formed at the other end. The inner diameter of the split rings 42 and 43 is set so that the inner peripheral edge can be loosely fitted to the rail portions 11 and 21, and as shown in FIGS. 5 and 6, a pair of the support tools is attached to the angle member 30. It is fixed in the longitudinal direction at an appropriate interval, the inner peripheral edges of the split rings 42 and 43 are loosely fitted to the rail portions 11 and 21, and the hook-shaped knob member 45 is engaged with the projection 46 to thereby split the split. The rings 42 and 43 are attached in a ring shape. As a result, the bird damage prevention rotator 40 is rotatably supported on the outer periphery of the support tool, and when the wild bird stops on the rod-like body 41, the bird damage prevention rotator 40 is rotated by its weight. Staying is prevented.
In FIG. 4, reference numeral 47 denotes hemispherical protrusions formed on both surfaces of the inner peripheral portions of the split rings 42 and 43, and the hemispherical protrusions 47 are formed on the rail portion 11 when the bird harm prevention rotating body 40 rotates. , 21 can be slidably brought into contact with the inner surface of the belt 21 to reduce friction, so that the bird damage prevention rotating body 40 can always rotate lightly by the weight of the wild bird.

In this embodiment, the groove-shaped rail portions 11 and 21 are formed on the outer peripheries of the semicircular arc member 10 and the semicircular arc member 20, but the outer peripheries of the semicircular arc member 10 and the semicircular arc member 20 are concave grooves. Even if it is not made into the rail part which consists of a mere plate-shaped outer periphery, the inner periphery of the rotating body for bird damage prevention is formed in a concave groove shape, and the outer periphery of the semicircular arc members 10 and 20 is prevented from bird damage. You may make it loosely fit in the concave inner peripheral edge of the rotating body for use.
Further, in this embodiment, the bird damage prevention rotating body 40 configured to stop the wild bird on the rod-like body 41 is shown, but a bird damage prevention rotating body in which a wire is stretched instead of the rod-like body 41 may be used. . That is, it may be a bird damage prevention rotating body configured such that a wire is stretched between a pair of rings provided at an appropriate interval and a wild bird is stopped on the wire. Further, in this embodiment, an example is shown in which a pair of bird damage prevention rotating body support tools are fixed to the angle member 30 at a predetermined interval. However, the bird damage prevention rotating body support tool according to the present invention is a It is also possible to fix a number of bird damage prevention rotating body support tools to the angle member of the book, and to continuously provide the bird damage prevention rotating body in the longitudinal direction. On the other hand, as shown in Patent Document 3, for example, the bird damage prevention rotating body can be rotatably supported by only one supporting tool. In short, the bird damage prevention rotating body support tool according to the present invention can support not only the bird damage prevention rotating body shown as the embodiment but also various shapes of bird damage prevention rotating bodies.

  Thus, the bird damage prevention rotary body support device according to the present invention sandwiches the angle member 30 having an L-shaped cross section between the V-shaped receiving portion 17 and the convex crimping portion 25 having an opening angle of 90 degrees, Since the convex crimping portion 25 is connected to the inner peripheral edge of the other semicircular member 20 by curved elastic arms 26a and 26b on both sides, the semicircular member 10 and the semicircular member 20 are joined together. When worn, the convex crimping portion 25 can sandwich the angle member 30 with a strong force due to the elasticity of the high elastic portions 26a and 26b and with an excellent elasticity such as a metal leaf spring. Such an action is caused by the fact that the highly elastic portions 26a and 26b are formed in a curved arm shape. For this reason, even if there is a slight difference in the thickness or width of the angle member 30, the angle member 30 can always be firmly clamped and fixed without being displaced for a long period of time. For example, a steel material constituting the angle member generally has a thickness of 4 mm to 6 mm, but the support tool according to the present invention can be firmly fixed to any of these angle members. Moreover, even when the support tool is fixed to an angle member that is slanted like the angle member constituting the steel tower, it is fixed immovably over a long period without shifting due to its own weight, etc., and can prevent bird damage. .
