Description

  The present invention relates to an attachment device for attaching a nesting device to a brace fixed to a utility pole.

  Conventionally, a nest protector has been installed on a brace fixed to a utility pole in order to prevent bird damage. For example, a technique shown in Patent Document 1 below has been proposed as an attachment device that attaches the nest-proofing device to the brace. The attachment device disclosed in Patent Document 1 (see in particular FIG. 6) has an upper arm portion and a lower arm portion, and the armor having a rectangular cross section is sandwiched between the upper arm portion and the lower arm portion. This is a fixed configuration.

In order to attach the nesting device to the arm using this attachment device, the upper arm portion to which the nesting device is fixed in advance is engaged with the upper surface and one side surface of the arm metal, and the entire attachment device is temporarily armed. The procedure is carried out in such a manner that the state is held in gold, the lower arm portion is subsequently lifted, and the shaft portion in the vicinity of the protruding portion of the lower arm portion is inserted into the slit-like groove of the upper arm portion.
However, it is difficult for an operator to perform the above-described detailed work by the indirect hot wire method used in recent years, and much labor is required.

Therefore, Patent Document 1 proposes the following attachment device.
That is, it has a configuration having a bolt fixed to the arm metal side, a mounting plate in which a hole is inserted and a bolt is inserted, and a nut member screwed into the bolt.
In order to attach the nest to the arm using this attachment device, the bolt is fixed to the arm in advance, and the mounting plate on which the nest is fixed is moved to above the bolt. The hole is aligned with the bolt and lowered so that the hole is inserted into the upper part of the bolt protruding upward from the upper surface of the arm metal, and the fixture is placed on the arm metal, and then the nut member is mounted on the upper part of the bolt. It is performed by the procedure of fastening.

JP 2007-174968 A

  However, such an installation operation includes an operation of fastening a nut to a bolt, which is a difficult operation to perform using the indirect hot wire method, and imposes a burden on the operator accordingly. It has become work.

  In view of the above problems, an object of the present invention is to provide an attachment device that can attach a fender to a brace with as little effort as possible and can reliably prevent it from falling off the brace.

  The present invention is an attachment device for attaching a nesting device to a bracelet having a rectangular cross-sectional shape, and a fixing portion for fixing the nesting device, and a fixing portion integrally provided on the fixing portion and attached to the armrest A clip part, and the clip part has a clamp member that is locked to the outer surface of the arm metal so as to be non-rotating with respect to the arm metal in the attachment attitude to the arm metal, and the attachment position of the clamp member And a holder that is mounted on the clamp member and holds the mounting posture is provided.

In the above configuration, the clamp member is attached to the arm metal so that the clamp member is locked to the outer surface of the arm metal and the clip portion is not rotated with respect to the arm metal, and the holding member is attached to the clamp member. The mounting posture is maintained.
By doing so, the clip part can be attached to the arm metal without performing the operation of tightening the nut to the bolt. Mounted on the bracelet.

In particular, when attaching a nest to a brace using the indirect hot wire method, there is no work of tightening a nut on a bolt, so the work of attaching the nest is extremely small.
In order to remove the nesting tool from the arm for maintenance or the like, the holder is removed from the clip portion, and the grip of the arm from the clamp member is removed.

  Since the attachment device of the present invention has a fixing portion for fixing the shroud portion and a clamp member that is mounted so as to sandwich the side surface of the armature having a rectangular cross section, the troublesome work of fastening the nut to the bolt By sandwiching the side surface of the arm metal by the clamp member without needing, it is possible to attach the fixing part to which the nest part is fixed to the arm metal, and by attaching the holder to the clamp member, The non-rotating state with respect to the arm metal can be securely held, and the attachment device can be effectively prevented from falling off the arm metal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a bullproof device attaching apparatus according to an embodiment of the present invention will be described with reference to the drawings. The nest prevention means not only the nesting of birds such as crows but also the prevention of bird damage in a broader sense.
FIG. 1 is a front view showing a state in which the protective device attaching device is attached to a brace, FIG. 2 is a side view of the same, FIG. 3 is a perspective view showing a relationship between a fixing portion and a clip portion, and FIG. FIG. 5 is a schematic front view and FIG. 5 is a schematic front view after installation.

The nesting device attaching apparatus 1 in this embodiment is an apparatus for attaching the nesting device 2 to the armrest 3.
The arm metal 3 is held substantially horizontally on the upper part of the electric pole 4 by using appropriate fixing means such as a binding band 4a, and the arm metal 3 is formed in the same rectangular cross section in the longitudinal direction. The outer surface of such a brace 3 is constituted by an upper surface 3a, a lower surface 3b, and both side surfaces 3c, 3c, and each surface is formed as a flat surface.

The nesting device attaching apparatus 1 has a fixing plate (fixing part) 5 for detachably fixing the nesting device 2. The fixing plate 5 is formed of a horizontal flat plate arranged in parallel with the upper surface 3a of the arm metal 3, and the attachment hole 5a of the fender 2 is formed through substantially the center of the plate surface.
The nest protector 2 is a known radial saddle-type nest protector, specifically, a base portion 6 and a plurality of needle-like bodies 7 extending upward or obliquely upward from the upper portion of the base portion 6. It is configured.

A bolt 10 protrudes downward from the lower surface of the base portion 6, and the bolt 10 penetrates the attachment hole 5 a from above and protrudes downward from the lower surface of the fixing plate 5. Are screwed together and fastened. With such a configuration, the nesting device 2 is detachably fixed to the fixing plate 5.
A spring support portion 12 is integrally formed at the front portion of the fixed plate 5. The spring support portion 12 is formed in a plate shape that is set to be thicker than the fixed plate 5.

The nesting apparatus attaching device 1 has a clip portion 13 that is provided integrally with the fixing plate 5 and is attached to the arm metal 3. The clip portion 13 includes clamp members 14 and 14, operation members 15 and 15 for opening and closing the clamp members 14 and 14, and kick springs 16 and 16. The clamp members 14 and 14, the operation members 15 and 15, and the kick springs 16 and 16 are provided in a pair of left and right.
Among these members constituting the clip portion 13, the clamp members 14 and 14 and the operation members 15 and 15 are integrally formed. Specifically, the clamp members 14 and 14 constitute the lower part of the clip part 13, and the operation members 15 and 15 constitute the upper part of the clip part 13.

The clamp members 14, 14 have flat plate-like holding walls 17, 17 that can be locked to both side surfaces 3 c, 3 c of the arm metal 3 by sandwiching both side surfaces 3 c, 3 c of the arm metal 3 from the left and right, and the arm metal 3 It has plate-like claw members 18 and 18 that can be locked to the lower surface 3b. The claw members 18 and 18 are integrally formed at the lower end portions of the sandwiching walls 17 and 17, respectively. The claw members 18, 18 are extended in a direction perpendicular to the sandwiching walls 17, 17 from the lower ends of the sandwiching walls 17, 17 so as to face each other (to face each other).
The lengths of the claw members 18, 18 in the left-right direction are set to be smaller than half of the left-right width of the lower surface 3 b of the armrest 3, and the claw members 18, 18 are closer to the left and right regions of the lower surface 3 b, respectively. Opposing in the vertical direction.

Thus, the clamping walls 17 and 17 and the claw members 18 and 18 of the clamp members 14 and 14 can be locked to both side surfaces 3c and 3c and the lower surface 3b, respectively. Thus, it has a structure that can be locked to the outer surface of the armrest 3 so as to be non-rotating. Therefore, the clamp members 14 and 14 are set to a predetermined length in the front-rear direction so as not to rotate with respect to the arm metal 3.
In this case, the term “lockable” means that the holding walls 17 and 17 can be opposed to the both side surfaces 3c and 3c in a substantially contacted state in the left-right direction, and the claw members 18 and 18 are substantially in contact with the lower surface 3b. It means a state that can be opposed in the vertical direction.

  Locking projections 20 and 20 projecting outward are formed at substantially the centers of the outer surfaces of the holding walls 17 and 17, respectively. The locking projections 20 and 20 are provided to hold a holder 21 to be described later, and the holder 21 will be described in detail later.

The operation members 15, 15 are formed to extend further upward from the upper end front side of the sandwiching walls 17, 17.
On the outside of the upper end portions of the operation members 15 and 15, the operation tool C does not slip or reliably when it is gripped by the operation tool C such as a yatco while being held between the upper end portions of the operation members 15 and 15. There are provided gripped portions 22, 22 formed in a concavo-convex shape so that they can be gripped.

A pair of left and right support protrusions 23 and 23 are formed on the front surface of the spring support portion 12 so as to protrude forward. The kick springs 16 and 16 are held so as to be fitted onto the support protrusions 23 and 23, respectively. One end portions of the kick springs 16 and 16 are fixed to the front surface of the spring support portion 12, and the other end portions are fixed to the front surfaces of the operation members 15 and 15. The kick springs 16 and 16 urge the clip portion 13 in a direction in which the operation members 15 and 15 are separated from each other around the kick spring and the clamp members 14 and 14 are brought closer to each other around the kick spring.
That is, the clip portion 13 is provided so as to be swingable around the kick springs 16 and 16 within a vertical plane.

  The nesting device attaching apparatus 1 includes the holding device 21. The holding tool 21 is packaged so as to be held between the clamping walls 17 and 17 of the clamp members 14 and 14 so as to hold the clamp members 14 and 14 in a posture locked to the outer surface of the arm metal 3. And the holder 21 is provided in the clamp members 14 and 14 so that attachment or detachment is possible.

The holding tool 21 has plate-like first holding walls 25 and 25 that overlap the left and right outer sides of the holding walls 17 and 17 and a second holding wall 26 that overlaps the claw members 18 and 18 from below, and is open upward. It has a U-shaped cross section. The holder 21 is formed to have a length in the front-rear direction substantially equal to the clamp members 14 and 14 so as to cover the clamp members 14 and 14.
On the lower surface of the second holding wall 26, a bulging portion 31 that is gripped by the operation tool C is formed.

The first holding walls 25, 25 are formed with holes 27, 27 that engage with the locking projections 20, 20. Further, the first holding walls 25, 25 are provided with the first holding walls 25, 25 so that the locking projections 20, 20 engage with the holes 27, 27 when the clamp members 14, 14 are mounted. The slit parts 30 and 30 (refer FIG. 2) for guiding along are formed.
The slit portions 30 and 30 are formed to extend from the upper ends of the first holding walls 25 and 25 to the hole portions 27 and 27, and the upper end side is formed wide and the hole portions 27 and 27 side are formed narrow. The width of the slits 30 and 30 on the side of the holes 27 and 27 is set to be smaller than the diameter of the holes 27 and 27.
In addition, the said nest protector attachment apparatus 1 is formed with the synthetic resin except kick springs 16 and 16.

  A procedure for mounting the snare fitting attaching device 1 having the above-described configuration to the arm metal 3 will be described. In this case, an indirect hot wire method is used. First, the fender 2 is fixed to the fixing plate 5 with bolts 10 and nuts 11. In this way, the nest protector mounting apparatus 1 in a state where the nest protector 2 is fixed is gripped by the operating tool C and positioned above the armrest 3. At this time, the clip portion 13 has kick springs 16, 16. Since the operation members 15 and 15 are rotated around the support protrusions 23 and 23 so as to be separated from each other due to the elasticity of the operation members 15 and 15, the operation members 15 and 15 are made to approach each other against the elasticity of the kick springs 16 and 16. The gripping portions 22 and 22 are gripped by the operating tool C. Then, the nest protector mounting apparatus 1 is moved to above the armrest 3.

When the gripping portions 22 and 22 are gripped by the operating tool C so that the operating members 15 and 15 are brought close to each other, the claws 18 and 18 of the clamp members 14 and 14 are separated from each other. The device 1 is lowered so that the arm metal 3 enters between the claw members 18 and 18, and the nesting device attaching device 1 is further lowered (see FIG. 4). Then, when the lower surface of the spring support 12 is placed on the upper surface 3 a of the arm metal 3, the grip by the operation tool C is released.
Then, due to the elasticity of the kick springs 16, 16, the operation members 15, 15 of the clip portion 13 are separated from each other, and the clamp members 14, 14, that is, the clamping walls 17, 17, and the claw members 18, 18 approach each other. .

However, since the arm metal 3 exists between the clamp members 14 and 14, when the clamp members 14 and 14 approach each other, the clamping walls 17 and 17 come into contact with the side surface 3 c of the arm metal 3 from the outside (side). Then no further approach. Further, the claw members 18 and 18 are opposed to the lower surface 3b so as to contact from below the lower surface 3b of the arm metal 3.
That is, the clamping walls 17 and 17 are locked to the side surfaces 3 c and 3 c of the arm metal 3, and the claw members 18 and 18 are locked to the lower surface 3 b of the arm metal 3. Therefore, the outer surface of the arm metal 3 is in a mounting posture in which the outer surface of the arm metal 3 is covered on all sides by the spring support portion 12 and the clamp members 14, 14. The

  However, since wind loads, vibrations, and the like often act on the nest protector 2, it is necessary to more securely fix the nest protector 2 to the brace 3. Therefore, the holder 21 is attached to the clamp members 14 and 14.

That is, the bulging portion 31 formed on the lower surface of the second holding wall 26 is gripped by the operation tool C and lifted so that the clamp members 14 and 14 are inserted into the holding tool 21 from the opened portion. At this time, if the holding tool 21 is lifted so that the locking projections 20, 20 match the slit portions 30, 30 formed on the first holding walls 25, 25, the slit portions 30, 30 serve as guides, The holder 21 can be easily lifted with the clamp members 14 and 14 aligned in the front-rear direction. Moreover, since the slit parts 30 and 30 are formed wide at the upper end side, it is easy to align the slit parts 30 and 30 with the locking projections 20 and 20.
In addition, since the claw member 18 is locked to the lower surface 3b of the arm metal 3 in the vertical direction, the clamp members 14 and 14 are held in place even when the holder 21 is lifted.

When the holder 21 is further raised, the locking protrusions 20 and 20 enter the holes 27 and 27, and the width of the slits 30 and 30 on the holes 27 and 27 side is smaller than the diameter of the holes 27 and 27. Since it is set, the locking projections 20 and 20 are locked in the holes 27 and 27. This locking can prevent the holder 21 from falling off.
Since the first holding walls 25 and 25 of the holder 21 cover the support walls 17 and 17 on the side and the second holding wall 26 covers the claw members 18 and 18 from below, the clamp members 14 and 14 are on the side. The mounting posture of the clamp members 14 and 14 is maintained in a state covered with the lower three sides. For this reason, even if a wind load or the like is applied to the nest protector 2, the nest protector 2 can reliably hold the non-rotating state with respect to the brace 3. That is, it is possible to reliably prevent the nest protector 2 from coming off the armrest 3.

According to this embodiment, in order to attach the nesting device 2 to the brace 3, the operation members 15 and 15 of the clip portion 13 are brought close to each other with the operation tool C, and the clamping walls 17 and 17 (claw members 18 and 18). The nest protector 2 can be easily attached to the arm metal 3 by separating them from each other and covering the arm metal 3 from above. That is, since the difficult operation of tightening the nut with respect to the bolt using the operation tool C is unnecessary, the burden on the operator can be reduced by that much even when using the indirect hot wire method.
This becomes more conspicuous as compared with the conventional device, as the number of the fenders 2 attached to the arm 3 is larger.

In the above embodiment, the nesting device 2 has been described by taking a radial cocoon-type nesting device as an example. However, the nesting device 2 is not limited to this and may be other nesting devices.
Further, although the kick springs 16 and 16 are used as means for biasing the clip portion 13 in a predetermined direction, the invention is not limited to this.
