Description

[Technical Field]

[0001] The present invention relates to a bird damage prevention device that is attached to an overhead wire such as an electric wire. [Background technology]

[0002] Birds and animals may land on overhead wires such as electric wires. When birds and animals land on overhead wires, they soil the surrounding area with droppings, feathers, etc. Furthermore, if large birds or animals land on them, or if a large number of birds and animals land on them, it may cause damage to the overhead wires and short-circuit accidents.

[0003] In order to prevent such so-called bird damage, it is known to use bird damage prevention devices.

[0004] For example, Patent Document 1 describes a bird-damaging device for electric wires, which includes a plurality of clip portions, each of which is a cylindrical, elastically deformable clip portion detachably attached to an electric wire and has a peripheral wall with discontinuous portions extending in the axial direction. The discontinuous portions of the clip portion are provided with a pair of flange portions protruding in a direction perpendicular to the axial direction. Each flange portion has an insertion guide portion at both axial ends that inclines toward each other in the axial direction and expands as it moves away from the axis in a direction perpendicular to the axis. When an operator holds the clip portion on the side opposite the insertion guide portion, the operator abuts the insertion guide portion against the outer peripheral surface of the electric wire and applies force from the clip portion toward the electric wire. This causes the clip portion to elastically deform so as to separate the flange portions, thereby expanding the discontinuous portions. This allows the electric wire to pass through the discontinuous portions and be inserted into the clip portion. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-158332 Summary of the Invention [Problem to be solved by the invention]

[0006] Recently, bird pest control devices have been installed remotely using tools such as insulated pliers. However, it can be difficult to install bird pest control devices like those described in Patent Document 1 from a remote location.

[0007] The present invention has been made to solve the above-mentioned problems, and one of its objects is to provide a bird damage prevention device that can be more easily attached even from a remote location. [Means for solving the problem]

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to each embodiment, and the components can be modified and embodied without departing from the spirit of the present invention. Furthermore, various inventions can be formed by appropriately combining multiple components disclosed in each embodiment. For example, some components may be omitted from all the components shown in the embodiments. Furthermore, components of different embodiments may be appropriately combined.

[0012] In this specification, the "height direction" means the direction connecting the center position of the discontinuous portion in the circumferential direction of the clip portion 100 and the axial center of the clip portion 100 when the clip portion 100 is viewed along the axial direction c, and the "width direction" means the direction perpendicular to the height direction when the clip portion 100 is viewed along the axial direction c.

[0013] 1 is an external view showing the configuration of a bird pest prevention device 1 according to an embodiment of the present invention. The bird pest prevention device 1 is a device that is attached to an overhead line such as an electric wire to prevent bird damage. The bird pest prevention device 1 may be made entirely of a synthetic resin that has excellent electrical insulation, flexibility, and abrasion resistance, and in one embodiment, may be realized as an injection-molded product made of an opaque thermoplastic synthetic resin, such as a black, gray, or other colored polyethylene resin.

[0014] The bird damage prevention device 1 comprises at least one clip portion 100, a pair of grip portions 200, at least one rib portion 300, and a plurality of bird-deterrent protrusions 400.

[0015] At least one clip portion 100 is formed in a cylindrical shape and has a discontinuous portion 110 extending in the axial direction c at a portion of the circumferential direction. The discontinuous portion 110 is a portion where the clip portion 100 is divided at one location in the circumferential direction. In the illustrated embodiment, multiple clip portions 100 are provided. However, the number of clip portions 100 is arbitrary.

[0016] The pair of gripping portions 200 are arranged at opposing positions across the discontinuous portion 110 in the circumferential direction of the clip portion 100, and are spaced apart from each other in the circumferential direction and protrude outward in the radial direction of the clip portion 100 from the peripheral wall 120 of the clip portion 100. When the clip portion 100 is viewed along the axial direction c, assuming a vertical axis passing through the axial centers of the discontinuous portion 110 and the clip portion 100 and a horizontal axis passing through the axial center of the clip portion 100 and perpendicular to the vertical axis, and assuming that the position of the discontinuous portion 110 is at a 270° position in the coordinate system of the vertical and horizontal axes, when the pair of gripping portions 200 are arranged within a range of 60° to 120°, it can be understood that the pair of gripping portions 200 are arranged at opposing positions across the discontinuous portion 110.

[0017] At least one rib portion 300 extends in the axial direction c of the clip portion 100 inside the pair of gripping portions 200 in the circumferential direction of the clip portion 100 .

[0018] By gripping the pair of gripping portions 200 with a tool such as an insulated operating rod (pliers), the clip portion 100 is elastically deformed, and the discontinuous portion 110 of the clip portion 100 can be expanded. Then, the overhead wire is inserted into the inside of the clip portion 100 through the discontinuous portion 110, and the bird pest control device 1 can be attached to the overhead wire. By providing the rib portion 300 as described above, the discontinuous portion of the clip portion 100 can be more easily expanded by gripping the gripping portion 200, making it easier to attach the clip portion 100 even from a remote location. The rib portion 300 can reduce the force required to grip the gripping portion 200 with a tool such as an insulated operating rod (pliers) in order to elastically deform the clip portion 100.

[0019] The bird barrier protrusions 400 protrude radially from the clip part 100. Providing such bird barrier protrusions 400 can prevent birds and animals from landing on the clip part 100. The bird barrier protrusions 400 only need to be provided to provide an obstacle for birds and animals, and the number of bird barrier protrusions 400 and the spacing between the bird barrier protrusions 400 may be set appropriately. There are no limitations on the length by which the bird barrier protrusions 400 protrude from the clip part 100.

[0020] The height of the pair of gripping portions 200 in the height direction may be 15 mm or more and 25 mm or less from the apex of the arc of the clip portion 100 in the circumferential direction. The maximum separation distance between the pair of gripping portions 200 in the width direction is assumed to be shorter than the maximum separation distance between a pair of jaws of pliers, but may be, for example, 65 mm or less. The opening angle between the pair of gripping portions 200 in the circumferential direction is not particularly limited, but may be, for example, 20° or more and 40° or less from the viewpoint that the pair of jaws of a tool such as an insulated operating rod (pliers) can easily grip the pair of gripping portions 200.

[0021] The height position of the rib portion 300 is not particularly limited, but is as follows. That is, the ratio of the length from the apex to the lowest point of the rib portion 300 to the length from the apex to the bottom point when the peripheral wall 120 of the clip portion 100 in the height direction is extended circumferentially may be, for example, 18% or more and 25% or less. Although not shown, the rib portion 300 may have at least one opening. The size of the opening of the rib portion 300 is not particularly limited, but may be large enough so that it does not cause any deformation when gripped by the gripping portion 200.

[0022] From the viewpoints of reducing weight, reducing wind pressure load, improving visibility of the attached state, etc., one or more holes 140 may be provided in the peripheral wall of the clip part 100. The holes 140 may be of a size that does not cause deformation of the clip part 100 even when the grip part 200 is gripped. The holes 140 may be omitted.

[0023] The bird pest control device 1 may further include a pair of flange portions 500 that protrude outward in the radial direction of the clip portion 100 from the peripheral wall 120 of the clip portion 100 on both sides of the discontinuous portion 110 in the circumferential direction of the clip portion 100. The spacing between the pair of flange portions 500 in the circumferential direction of the clip portion 100 may increase with increasing distance from the peripheral wall 120 of the clip portion 100. When an overhead wire is inserted into the clip portion 100 through the discontinuous portion 110, the pair of flange portions 500 guide the overhead wire to the discontinuous portion 110.

[0024] Next, Figure 2 is a front view of the bird pest prevention device 1 of Figure 1, Figure 3 is a partially enlarged cross-sectional view showing the configuration of the upper part of the bird pest prevention device 1 of Figure 1 in the axial direction c, and Figure 4 is an enlarged view of the discontinuous portion 110 of the clip portion 100 of the bird pest prevention device 1 of Figure 1.

[0025] 3, the rib portion 300 may protrude toward the inside of the clip portion 100 with respect to an extension plane obtained by extending the peripheral wall 120 of the clip portion 100 on the outer side of the pair of gripping portions 200 in the circumferential direction of the clip portion 100. However, the rib portion 300 may also protrude toward the outside of the clip portion 100 with respect to the extension plane.

[0026] As particularly shown in FIG. 3 , the clip portion 100 includes a first peripheral wall 122 and a second peripheral wall 124, each of which has one circumferential end connected to each other via a rib portion 300 and a discontinuous portion 110 between the other circumferential ends. The rib portion 300 also includes a first side wall 322 connected to the first peripheral wall 122, a second side wall 324 connected to the second peripheral wall 124, and a connecting portion 330 connecting the other end of the first side wall 322 to the other end of the second side wall 324. The first side wall 322 and the second side wall 324 of the rib portion 300 may extend on the same straight line as the pair of gripping portions 200. That is, in the illustrated embodiment, the shape of the rib portion 300 is V-shaped when the clip portion 100 is viewed along the axial direction c as shown in FIG. 3 . However, the shape of the rib portion 300 is not limited thereto and may be, for example, U-shaped or bellows-shaped.

[0027] A protruding piece 130 may extend circumferentially from the other end of at least one of the first peripheral wall 122 and the second peripheral wall 124 so as to overlap the discontinuous portion 110 when viewed in the radial direction. After the overhead wire is inserted into the clip portion 100, the protruding piece 130 prevents the overhead wire from passing through the discontinuous portion 110 and slipping out of the clip portion 100.

[0028] Next, FIG. 5 is a partially enlarged front view showing the configuration of the upper part of the bird pest prevention device 1 of FIG. 1, and FIG. 6 is a partially enlarged front view showing the pair of gripping parts 200 of FIG. 5 before being gripped with pliers 1000.

[0029] As shown in Fig. 5, an over-insertion prevention protrusion 410 may protrude from the outer surface of each of the pair of gripping portions 200 in the circumferential direction of the clip portion 100 below the upper ends of the pair of gripping portions 200. As shown in Fig. 6, the over-insertion prevention protrusion 410 prevents over-insertion of the pliers 1000. When an operator abuts the tip of the jaw portion 1100 of the pliers 1000 against the over-insertion prevention protrusion 410, the jaw portion 1100 of the pliers 1000 is positioned appropriately for grasping the gripping portion 200. The over-insertion prevention protrusion 410 also contributes to preventing birds and animals from approaching the overhead wire.

[0030] In addition, from the viewpoint of adjusting the position of the jaw portion 1100 of the pliers 1000 to a position suitable for grasping by the gripping portion 200, it is preferable that the distance in the width direction from the tip of the over-insertion prevention protrusion 410 to the tip of the other over-insertion prevention protrusion 410 positioned opposite the over-insertion prevention protrusion 410 is shorter than the maximum separation distance between the pair of jaw portions of the pliers, but the distance in the width direction from the tip of the over-insertion prevention protrusion 410 to the tip of the other over-insertion prevention protrusion 410 may be, for example, more than 65 mm and 80 mm or less.

[0031] Next, Figure 7 is a partially enlarged external view showing the configuration of the clip portion 100 of the bird pest prevention device 1 of Figure 1, Figure 8 is a partially enlarged external view showing another configuration of the clip portion 100 of the bird pest prevention device 1 of Figure 1, and Figure 9 is a partially enlarged external view showing another configuration of the clip portion 100 of the bird pest prevention device 1 of Figure 1.

[0032] As shown in FIG. 7 , the extension length of the rib portion 300 in the axial direction c of the clip portion 100 may be shorter than the entire length of the clip portion 100 in the axial direction c. While FIG. 7 shows an embodiment in which one rib portion 300 is provided on one clip portion 100, as shown in FIG. 8 , at least one rib portion 300 may include multiple rib portions arranged side by side in the axial direction c of the clip portion 100. Furthermore, as shown in FIG. 9 , the rib portion 300 may extend over the entire length of the clip portion 100 in the axial direction c. In any of the above embodiments, when attaching the bird prevention device 1 to an overhead wire, the rib portion 300 can relatively easily expand the discontinuous portion 110 of the clip portion 100 by gripping the gripping portion 200 with a relatively small force. As a result, an operator can easily attach the bird prevention device 1 to an overhead wire.

[0033] Next, FIG. 10 is a partially enlarged front view showing the configuration of the upper part of another embodiment of the bird damage prevention device 1 of FIG.

[0034] As shown in Figure 10, the thickness of at least a portion of the rib portion 300 may be thinner than the thickness of the peripheral wall 120 of the clip portion 100. This allows the discontinuous portion 110 to be expanded with less force. The reduction rate of the thickness is not limited, but may be, for example, 30% to 40%. Here, the reduction rate of the thickness is expressed as [{(thickness (mm) of the peripheral wall 120 of the clip portion 100) - (thickness (mm) of at least a portion of the rib portion 300)} / (thickness (mm) of the peripheral wall 120 of the clip portion 100)] x 100%.

[0035] Next, FIG. 11 is a side view showing the configuration of the bird damage prevention device 1 of FIG.

[0036] As shown in FIG. 11 , at least one clip portion 100 may include a first clip portion 100 and a second clip portion 102. The bird pest control device 1 may further include a connecting portion 150 connecting one end of the first clip portion 100 and one end of the second clip portion 102 in the axial direction c. The connecting portion 150 may be a portion formed with a convex cross section and may be molded integrally with the first clip portion 100 and the second clip portion 102. Alternatively, the connecting portion 150 may have an engaging body extending from one end of one of the first clip portion 100 and the second clip portion 102 and an engaging hole provided in the other end of the first clip portion 100 and the second clip portion 102, and the engaging body may be engaged with the engaging hole to connect the first clip portion 100 and the second clip portion 102. The connecting portion 150 is not limited to these embodiments, and known techniques may be used as appropriate.

[0037] As in the illustrated embodiment, at least one clip portion 100 may further include a third clip portion 104, and the connecting portion 150 may further connect one end of the second clip portion 102 and one end of the third clip portion 104 in the axial direction c. However, the number of clip portions 100 is arbitrary and may be four or more. Conversely, the number of clip portion 100 may be one. When the number of clip portion 100 is one, the connecting portion 150 may be omitted.

[0038] Although the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to these examples. It is clear that a person skilled in the art to which the present invention pertains can conceive of various modifications and alterations within the scope of the technical ideas set forth in the claims, and it is understood that these also naturally fall within the technical scope of the present invention.
