[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a Bunsen hardware relates Bunsen hardware especially can secure attachment from the ground side to the support line.
[0002]
[Prior art]
When a communication cable or the like installed on a utility pole is drawn into a building or the like, a separating hardware is used to branch the lead-in support line from the support line. FIGS. 5A and 5B are explanatory views showing the form of a conventional segmented hardware, wherein FIG. 5A is a top side view and FIG. 5B is a front view. As shown in these drawings, the segmented hardware 1 includes a hook fitting 2 that can lock an outdoor wire retainer (not shown) and a pair that is inserted into the base side end of the hook fitting 2 and is clamped to a support line. Support plate 3 (3L, 3R).
[0003]
At the base side end of the hook metal fitting 2, there is a male screw portion that enables screwing with the nut 4 and a support plate stopper 5 for preventing the support plate 3 from moving to the tip side of the hook metal fitting 2. Is provided. By tightening the nut 4, the support wire can be clamped by the recess 6 provided in the facing portion of the support plate 3.
[0004]
When fixing such a segment metal fitting 1 to a support line, first, a foam material piece 7 serving as a mounting aid is sandwiched between a pair of support plates 3, and the nut 4 is slightly tightened so that the support line is interposed between the support plates 3. Produces easy entering intervals. Then, the segment metal fitting 1 is mounted on a segment metal fixture (not shown), and the support line is accommodated in the concave portion 6 by visual operation from the ground, and then the ratchet wrench equipped on the segment metal fixture is attached. The nut 4 is tightened to fix the metal part 1 to the support wire.
[0005]
[Problems to be solved by the invention]
However, since the support wire exists at a high place, it has been difficult to visually confirm the mounting state of the segment metal fitting to the support wire by the conventional mounting method. For this reason, when a rotational moment or the like is applied to the concave portion 6 by tightening the nut 4 or the like, the support wire is not properly fitted in the concave portion 6 and the gripping becomes insufficient, and there is a possibility that the segment metal fitting 1 falls.
[0006]
Further, the support plate 3R on the side in contact with the nut 4 is held only by the compressive force of the foam piece 7 without the guide groove 8 entering the distal end side of the hook fitting 2 when the support line is inserted. For this reason, there is a problem that when the support wire comes into contact or the nut 4 is tightened, the support plate 3R rotates around the hook metal fitting 2 due to friction, and the separating metal fitting 1 cannot be reliably fixed to the support wire.
[0007]
The present invention pays attention to the above-mentioned conventional problems, and can confirm the mounting state of the segmented hardware with respect to the support line by the feel and mounting sound during operation, and the relative position between the support plates can be maintained even when an external force is applied to the support plates. It is an object of the present invention to provide a segmented hardware that can be securely attached to a support wire without changing.
[0008]
[Means for Solving the Problems]
In the present invention, when a support wire introduction port that can be expanded by a pressing force from the support wire is provided in the mounting aid for the segmented hardware, a pressing reaction force (resistance force) when passing through the support wire introduction port. This is based on the knowledge that it is possible to confirm the mounting state of the metal fittings with respect to the support line by the change of the above and the sound generated by the passage through the support line introduction port.
[0009]
That is, the segment metal fitting according to the present invention is a segment metal fixture having a pair of support plates inserted into the base side end of the hook metal fitting, and holding the support wires by the concave portions provided in the support plates. A through hole is formed in the mounting aid formed of an elastic body, the root side end is inserted into the through hole, the mounting aid is interposed between the support plates, and the mounting aid is A support wire introduction port set narrower than the diameter of the support wire; and provided on the support wire introduction port side of the through hole and set to a larger diameter than the support wire introduction port and in the recess This is a configuration provided with a support wire wrapping portion that has a shape to follow and fits with the concave portion.
[0012]
[Action]
According to the above configuration, when the support wire is pressed against the support wire introduction port, the support wire introduction port is expanded by an elastic action, and the support wire moves to the support wire wrapping portion. When the support line passes through the support line introduction port, the pressing reaction force (resistance force) applied to the support line is increased or decreased, so that the mounting state of the segment hardware relative to the support line can be confirmed by touch. Further, after the support line has passed through the support line introduction port, the pressing force for expanding the support line introduction port is released, so that the support line wrapping portion comes into contact with the support line. Since a contact sound (collision sound) is generated by this contact, it is possible to confirm the attachment state of the separated hardware to the support line by hearing. Further, since the segment metal fitting is attached to the segment metal fixture, it can be moved to the support line existing at a high place by the operation rod and attached to the support line.
[0013]
In addition, since the support plates are connected to each other via the attachment assisting device main body by fitting the concave portion and the support wire wrapping portion, the attachment assisting device main body receives this even if a rotational force is applied to the support plate on one side. The rotational force is transmitted to the other support plate side. For this reason, it is possible to prevent the relative position between the support plates from fluctuating.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the segmented hardware according to the present invention will be described in detail with reference to the drawings.
[0015]
FIG. 1 is an enlarged view of a main part when a segmented hardware is mounted on a segmented hardware fixture, and FIG. 3 is a state explanatory diagram showing a procedure for mounting the segmented hardware on the segmented hardware fixture. As shown in these drawings, a segment metal fitting 12 to which a V-shaped leaf spring 10 serving as an attachment auxiliary tool body is attached includes a hook fitting 16 that can lock an outdoor line retainer 14, and the hook fitting 16. It is composed of a pair of support plates 18 that are inserted into the root side end portion 16 </ b> A and sandwich the support line.
[0016]
The hook metal fitting 16 has a form in which a metal round bar is bent in a substantially U shape, and a male thread portion that enables screwing with the nut 20 is provided at the base side end portion 16A serving as a guide shaft. Yes. Further, a brim-shaped support line stopper 22 for preventing the support plate 18 from moving toward the distal end portion 16 side is provided on the inner side of the male screw portion at the root end portion 16A.
[0017]
A pair of support plates 18 (18L, 18R) inserted through the root side end portion 16A is provided with a semicircular recess 24 at the facing portion, and the support wire 26 is formed by abutting the recesses 24 together. Is possible. A communication cable 27 is suspended below the support line 26. Further, a gap due to thinning exists between the concave portion 24 in the facing portion of the support plate 16 and the through hole 25 through which the base side end portion 16A is inserted, so that a mounting space for the V-shaped leaf spring 10 is formed. ing. Further, a guide groove 28 is formed on the upper portion of the support plate 18, that is, on the opposite side of the concave portion 24 across the root side end portion 16A, and the end portion 16B of the hook metal fitting is taken into the guide groove 28, thereby The support plate 18 can be prevented from rotating around 16A.
[0018]
The form of the V-shaped leaf | plate spring 10 used for such a split metal fitting 12 is demonstrated below. FIG. 2 is an explanatory view of the structure of the mounting aid for the segmented hardware according to the present embodiment. As shown in the figure, the V-shaped leaf spring 10 is formed by bending a spring material made of a flat plate into a V-shape so as to be symmetrical. A through hole 34, a support wire wrapping portion 36, and a support wire introduction port 38 are formed in this order from the bent root 30 side to the distal end side in the leg portion 32 extended in a V shape from the bent root 30. Yes. Here, the diameter of the through hole 34 is set to be slightly larger than the outer diameter of the hook metal fitting 16, and the V-shaped leaf spring 10 can be moved along the root side end portion 16A. Further, a support wire wrapping portion 36 is provided on the distal end side of the through hole 34 in the leg portion 32, that is, in the center portion of the leg portion 32. The support wire wrapping portion 36 is bent so as to follow the shape of the concave portion 24 in the support plate 18, and therefore, when the space between the left and right leg portions 32 is narrowed, the support wire 26 is closely attached to the support wire 26. It is possible. A support wire introduction port 38 for introducing the support wire 26 is continuously formed from the support wire embedding portion 36. This is composed of an arc portion 38A that is bent in the opposite direction to the arc that forms the support wire embedding portion 36, and supports the butting interval (dimension A in the figure) of the arc portions 38A in the left and right leg portions 32. By setting the width smaller than the outer diameter of the wire 26, a resistance force is generated when the support wire 26 passes.
[0019]
A procedure for fixing the segment metal piece 12 to the support line 26 using such a V-shaped leaf spring 10 will be described.
When fixing the segmented metal object 12 to the support line 26, first, the V-shaped leaf spring 10 is inserted between the pair of support plates 18. For this attachment, the nut 20 and the support plate 18R may be removed from the base side end portion 16A, and the base side end portion 16A may be inserted through the through hole 34. Then, the V-shaped leaf spring 10 is sandwiched between the support plates 18 on both sides, and the support wire wrapping portion 36 is brought into close contact with the left and right recesses 24 to determine the relative position of the V-shaped leaf spring 10 with respect to the support plate 18. To do.
[0020]
After attaching the V-shaped leaf spring 10 to the segment metal fitting 12 in this way, the segment metal fixture 12 is attached to the segment metal fixture 40 on the ground surface side. The segment metal fitting 40 is provided with a wrench 42 corresponding to the nut 20 of the segment metal fixture 12. The nut 20 is attached to the wrench 42 and the segment metal fixture 12 is pressed from the opposite end. By doing so, the segment metal fitting 12 can be attached to the segment metal fixture 40. In addition, if the release chain 44 pulled out from the separating hardware fitting 40 is pulled, the pressing force of the separating hardware 12 can be released, and the separating hardware 12 and the separating hardware mounting 40 can be separated. It has become. Further, the segment metal fitting 40 is provided with a handle 46 for rotating the wrench 42 only in a predetermined direction and an extension chain 48 connected thereto, so that the nut 20 can be screwed together. An operating rod 50 that can be extended to the height of the support wire 26 can be attached to such a segmented metal fixture 40, and can be attached to the segmented hardware fixture 40 by moving the operating rod 50. The segmented hardware 12 thus made can be moved to the vicinity of the support line 26.
[0021]
After the operating rod 50 is moved and the segment metal fitting 40 is moved to the upper part of the support line 26, the operating bar 50 is pulled to the ground side and the support line 26 is pressed against the support line introduction port 38. When the support line 26 is pressed against the support line introduction port 38, the leg portion 32 expands (deforms) according to the magnitude of the pressing force, and the distance between the left and right arc portions 38A (dimension A in the figure) increases. To go. When this distance reaches the outer diameter of the support wire 26, the support wire 26 passes through the support wire introduction port 38 and moves to the support wire wrapping portion 36 side. Here, when the support line 26 passes through the support line introduction port 38, a pressing reaction force due to the restoration of the leg portion 32 is applied. That is, since the leg portion 32 expands from the contact of the support line 26 to the arc portion 38A to the top (narrowest width portion) of the arc portion 38A, the pressing force applied to the support line 26 is increased. Power increases. Then, when the support line 26 exceeds the top (narrowest width part) of the arc portion 38A, the force for pulling down the segment metal piece 12 and the restoring force of the leg 32 are applied to the support line 26, and the support line 26 is at once. It moves to the support wire embedding part 36 side. Thus, when the support line 26 passes through the support line introduction port 38, the pressing reaction force applied to the support line 26 increases and decreases, so that an operator operating the operation bar 50 feels transmitted from the operation bar 50. It is possible to confirm the mounting state of the segment metal fitting 12 with respect to the support line 26.
[0022]
As described above, when the support line 26 exceeds the top part (narrowest width part) of the arc part 38A, the force for pulling down the segment metal piece 12 and the restoring force of the leg part 32 are applied to the support line 26, and the support line 26 is supported. The wire | line 26 moves to a support wire attachment part at a stretch. For this reason, the support wire embedding part 36 contacts the surface of the support wire 26, and this contact generates a mounting sound (collision sound). From this mounting sound, the operator can also check the mounting status of the segment hardware 12 with respect to the support line 26.
[0023]
Further, in the state of the segment metal fitting 12 mounted on the segment metal fixture 40, the tip end portion 16B is not taken into the guide groove 28 of the support plate 18R. However, since the leg portion 32 having the support wire wrapping portion 36 that follows the left and right concave portions 24 connects the left and right support plates 18 via the bent root 30, even if a rotational force is applied to the support plate 18R. However, the spring restoring force does not act and the support plate 18R does not rotate. For this reason, it is possible to prevent the support plate 18R from rotating around the root end 16A due to the contact of the support line 26 with the support plate 18R generated during the operation, the tightening amount of the nut 20, and the like.
[0024]
After guiding the support wire 26 to the support wire wrapping portion 36 in this way, the extension chain 48 is pulled, the handle 46 is rotated, and the nut 20 is tightened with the wrench 42. After the nut 20 is tightened, the release chain 44 is pulled to release the pressing force from the segment metal fixture 40 applied to the segment metal fixture 12, and the segment metal fixture 40 is removed from the segment metal fixture 12. FIG. 4 shows a state diagram after attaching a metal part to the support line. In this state, the interval between the left and right leg portions 32 is narrowed by tightening the nut 20. For this reason, the restoring force of the leg part 32 acts on the thinned portion of the support plate 18, and the loosening of the nut 20 can be prevented.
[0025]
