  By the way, bird damage such as wild bird droppings or nesting is not limited to overhead lines such as electric wires, but is the same for steel towers and other buildings, for example, for angle members with an L-shaped cross section that composes steel towers. If the conventional rotary bird damage prevention device shown in the above cited documents 1 and 2 etc. is attached, the frictional resistance with the angle material becomes large, so there is a problem that the bird does not rotate smoothly even if the wild bird stops. At the same time, in the case of an angled member stretched diagonally, since the rotary bird damage prevention device is shifted downward by its own weight, there is a problem that it can not be fixed at a required position.

Further, even in the case of the stay preventing device disclosed 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 time, and the elastic engagement piece formed of a plastic material is elastically deteriorated by ultraviolet rays in a short time, and there is a problem that the fixation tends to be loose.
Moreover, although the rotary bird damage prevention device for overhead cables shown in Patent Document 4 is configured such that the rotary bird damage prevention device can be attached to the overhead cable, the cross section has a completely different cross-sectional shape from the overhead cable. It was impossible to attach the rotary birdcage protection device to the L-shaped angle material.
Furthermore, since the width dimension and thickness etc. of the L-shaped cross-sectional angle member which constitutes a tower etc. are not constant, in order to be able to fix firmly, the elastic engagement is individually made according to the width dimension and thickness conventionally There is a problem that it is necessary to design a piece, which increases the manufacturing cost.
Therefore, the present invention is intended to provide a rotary bird damage prevention device which can be easily and firmly attached to a building such as a steel tower made of an angled member having an L-shaped cross section.

  To this end, the rotary birdcage protection device according to the present invention comprises a parking protection rotary body and a support tool for rotatably supporting the parking protection rotary body, the support tool comprising a plurality of annular support members The annular supporting members are disposed at predetermined intervals by providing a rod-like body on each of the pair of semicircular supporting members each having a rail portion on the outer peripheral edge of which the parking rotation roller is rotatably supported. A V-shaped receiving portion formed of an arc-shaped member and having an open angle of 90 degrees is integrally formed on the inner peripheral edge of one semi-circular member, and the other semi-circular member faces the V-shaped receiving portion. Forming integrally a convex crimped portion on both sides by providing a highly elastic portion in the form of a curved arm continuous with the inner peripheral edge of the both ends of the semicircular arc member, and joining the pair of semicircular arc members in an annular shape; Ang whose cross section is L-shaped by the V-shaped receiving part and the convex crimping part Characterized in that the wood has to be resiliently mounted and clamped.

  The rotary birdcage protection device according to the present invention can be easily attached to a building such as a steel tower made of an angle member having an L-shaped cross section, and attached so as not to shift over a long period of time. Further, even if there are slight differences in the width dimension, thickness, etc. of the angle material, the cost can be reduced because it can be installed without any problem.

  Further, V is formed such that the downward opening angle α in FIG. 3 is 90 degrees by integrally forming a pair of oblique piece members 17 a and 17 b adjacent to the inner peripheral edge of one semicircular arc member 10. The letter shaped receiving portion 17 is integrally formed. Further, a convex crimped portion 25 having slope portions 25a and 25b opposite to the V-shaped receiving portion 17 is integrally formed on the other semicircular arc member 20. In addition, the flat part 25c is formed between both slope part 25a, 25b. The convex crimped portions 25 are integrally formed on the semicircular arc member 20 by providing curved elastic high elastic portions 26a and 26b continuous with the inner peripheral edge of the both ends of the semicircular arc member 20 on both sides. A reinforcing rib 19 is formed integrally and continuously from the inner circumferential surface of the semicircular arc member 10 to the back surface of the V-shaped receiving portion 17, and the convex crimped portion from the inner circumferential surface of the semicircular arc member 20. Reinforcing ribs 27 are integrally formed in series integrally on the back surfaces of the high elastic parts 26a and 26b, and by forming the reinforcing ribs 19 and 27, the V-shaped receiving part 17 and the high elastic parts 26a and 26b Rigidity and strength of the

Then, both ends of the rod-like members 3a and 3b are fitted to the bearing portions 28a and 28b, and an adhesive is appropriately applied to the fitting portions, so that both end portions of the rod-like members 3a and 3b are the bearing portions 28a. , 28b. By interposing the two rod-like members 3a and 3b between the annular supporting member 1a and the annular supporting member 1b as described above, the annular supporting member 1a and the annular supporting member 1b are arranged at a predetermined interval. The rod-like members 3a and 3b are formed so as to be lightweight and have high rigidity by applying a resin coating to the outer periphery of a rod made of a plurality of glass fibers. It may be molded with other materials such as a rod.

  The semicircular arc member 10 and the semicircular arc member 20 are engaged in an annular shape by engaging the projection 23 with the engagement hole 15 and engaging the hook-shaped knob member 18 with the projection 24. Ru. As shown in FIGS. 5 and 6 by the V-shaped receiving portion 17 and the convex crimped portion 25 at the time of joining, as shown by a two-dot chain line in FIG. The angled member 30 having an L-shaped surface is elastically fitted. Thereby, the support tool 1 according to the present invention can be fixedly fixed to the angle member 30.

In this way, the stationary rotation rotor 40 shown in FIG. 4 is rotatably provided on the outer periphery of the support tool 1 fixed to the angle member 30. In this parking preventing rotary body 40, half arc-shaped split rings 42 and 43 are provided at both ends of a plurality of rod-like members 41, and the split rings 42 and 43 can be opened and closed at the connecting portion 44 at one end. A hook-like knob member 45 provided at one end of one of the split rings 42 is engaged with a projection 46 formed at the other end. The dividing ring 42, 43 has an inner diameter dimension so that the inner peripheral edge can be loosely fitted to the rail portion 11, 21 as shown in FIG. 5 and FIG. The inner peripheries of the split rings 42 and 43 are loosely fitted to the rail portions 11 and 21 of the second embodiment, and the split rings 42 and 43 are joined in a ring shape by engaging the hook-like knob members 45 with the projections 46. As a result, the stationing prevention rotating body 40 is rotatably supported on the outer periphery of the support tool 1. Then, when a wild bird stops at the rod-like body 41, the parking protection rotary body 40 is rotated by the weight of the wild bird. This prevents wild birds from being stationed.
In FIG. 4, reference numeral 47 denotes hemispherical projections formed on both sides of the inner peripheral portion of the split rings 42 and 43, and the hemispherical projections 47 serve as rail portions 11 when the parking rotation body 40 rotates. The sliding contact with the inner surface 21 reduces the friction, so that the parking rotation body 40 can always be lightly rotated by the weight of a wild bird.

In this embodiment, the grooved rail portions 11 and 21 are formed on the outer circumferences of the semicircular arc member 10 and the semicircular arc member 20. However, the outer circumferences of the semicircular arc member 10 and the semicircular arc member 20 are grooved While the rail portion consists of a mere plate-like outer peripheral edge without forming it, the inner peripheral edge of the retention preventing rotary body is formed in a concave groove shape, and the outer peripheral edge of the semicircular arc members 10 and 20 is a rotation preventing retention. It may be loosely fitted to the concave inner peripheral edge of the body.
Further, in this embodiment, although the parking preventing rotary body 40 configured to stop the wild birds in the rod-like body 41 is shown, it may be replaced with the rod-like body 41 and a wire may be stretched. That is, a wire may be stretched between a pair of rings provided at appropriate intervals to make the wire stop wild birds.

Moreover, although the example which connected two cyclic | annular support members 1a and 1b by rod-shaped body 3a, 3b was shown in the support tool 1 shown to this embodiment, as needed, it connects a further many cyclic | annular support members. It is also good. That is, two or more annular support members can be connected in the longitudinal direction of the angle member by providing a rod-like body between them, and a parking rotation body can be provided rotatably on the support tool.
In the support tool 1 shown in this embodiment, the rod-like members 3a and 3b separate from the semicircular arc member 20 are provided between the pair of semicircular arc members 20, but a pair of semicircular arc members 20 And the rod-like body may be integrally formed of plastic.
In any case, in this support tool, the distance between the both annular support members is kept constant by providing the rod-like body, and therefore the above-mentioned stationary body rotating body 40 is mounted on the both rails 11 and 21 of this support tool. The two split rings 42 and 43 can be easily fitted loosely. It becomes easy to attach the stationary rotation roller to the support tool, and the installation work can be completed in a short time even if the work environment is severe, such as on a steel tower.

  Further, the support tool 1 of the rotary birdcage protection device according to the present invention sandwiches the angle member 30 having an L-shaped cross section by the V-shaped receiving portion 17 having an opening angle of 90 degrees and the convex crimping portion 25. The convex crimped portion 25 is connected to the inner peripheral edge of the other semicircular arc member 20 by the curved high elastic portions 26a and 26b on both sides, so that the semicircular arc member 10 and the semicircular arc member 20 can be When bonded, the convex crimped portion 25 can clamp the angle member 30 with a high strength and an excellent elasticity like a metal plate spring due to the elasticity of the high elastic portions 26a and 26b. Such an action is particularly caused by the high elastic portions 26a and 26b being formed in a curved arm shape. For this reason, even if there is a slight difference in the thickness, width, etc. of the angle member 30, the angle member 30 can be always firmly fixed and fixed without being displaced for a long time. For example, although 4 mm to 6 mm are generally used for the thickness of the steel material constituting the angle material, the support tool according to the present invention can be firmly fixed to any of these angle materials. Also, even when the support is fixed to an angled member such as an angled member constituting a steel tower, it can be fixed immovably over a long period without being displaced by its own weight etc., and bird damage can be prevented. .
