Description

[Detailed Description of the Invention] This invention relates to an attached pole for drawing in electric wires that is attached to a house or the like in order to hold down and support the electric wires drawn in from a utility pole or the like.

Conventionally, when connecting electric wires to houses from telephone poles, etc., there is a standard that the electric wires must be installed at least 5 meters above the ground on the road, but if the house is low, the standard height cannot be achieved, and various measures are required. .

This idea was devised in consideration of these points. A pole is erected on the roof of a house, etc., and the electric wire is drawn into the pole tube from the top, and the electric wire is pulled out from the bottom to ensure the standard height of the point where the wire is drawn. The object of the present invention is to provide an attached pole for leading in electric wires, which can be easily attached to various parts of a house and also improves the aesthetic appearance of the place where electric wires are led in.

An embodiment of this invention will be described below with reference to the drawings. Reference numeral 1 denotes a square tubular support arm, and this support arm 1 has a square tubular rising part 2 on the upper side of one end and a cylindrical part 3 on the other end. It is something.

4 is a bolt hole drilled on both sides of the rising portion 2 and on both sides of one end of the support arm 1 where this rising portion 2 is located; 5 is a pole whose lower end is passed through the cylindrical portion 3; 6 is a bolt hole of this pole 5; Convex stoppers 6 are provided at opposing positions on the outer periphery of the lower portion, and the convex stoppers 6 are in contact with the upper edge of the cylindrical portion 3.

Reference numeral 7 denotes a locking protrusion having protrusions at both ends of a saddle portion having a semicircular cross section, and the locking protrusion 7 abuts and fixes its own saddle portion to an appropriate location on the outer periphery of the pole 5.

Reference numeral 8 denotes a locking hole drilled in the protrusions on both sides of the locking protrusion 7, 9 a rubber bushing for protecting electric wires which is capped on the upper and lower edges of the pole 5, and 10 a rubber bushing on the rising portion 2 of the support arm 1. This auxiliary tool 10 can be installed freely, and this auxiliary tool 10 consists of a vertical plate 11 and a horizontal plate 12 made by bending a channel template at right angles, and a hook 13 facing outward is provided at the center of the upper end of the vertical plate 11. ,
Bolt holes 14 are bored in each of the vertical plate 11 and the horizontal plate 12, and the vertical plate 11 of the vertical plate 11 and the horizontal plate 12
Both proximal edges each have an outwardly directed channel edge 15.

The vertical plate 11 is arranged so that the channel edge 15 of the auxiliary tool 10 comes into contact with both narrow sides of the rising portion 2 of the support arm 1.
is applied to the rising portion 2, and the hook 13 is hooked onto the upper edge of the rising portion 2.

The outer and inner circumferences of the pole 5 and the locking protrusion 7 are each coated with an insulating resin.

This invention has the above structure, and a stainless steel band 17 is wrapped around the end side of the main building 16 that supports the roof of the house.
The vertical plate 11 and the horizontal plate 12 of the auxiliary tool 10 are brought into contact with the side and bottom surfaces of the main building 16, respectively, and bolts, screws, or nails are driven through the bolt holes 14 of the horizontal plate 12 to provide assistance. Temporarily fasten the tool 10 to the main building 16, lock the upper end edge of the rising part 2 of the support arm 1 to the hook 13 of this auxiliary tool 10, and fit both narrow sides of the rising part 2 between both channel edges 15. and support arm 1 as described above.
The supporting arm 1 is bolted, screwed or nailed to the main building 16 through the bolt hole 4 of the rising part 2 and the bolt hole 14 of the vertical plate 11 of the auxiliary tool 10. Fix it.

Note that when fixing the support arm 1 to the main building 16, instead of attaching the supporting tool 10 to the main building 16 first and then fixing the rising part 2 as described above, instead of attaching the supporting tool 10 to the main building 16 in advance. 13 to the upper edge of the rising part 2, and fitting both narrow sides of the rising part 2 between both channel edges 15, and then abutting against the main house 16 to fix the auxiliary tool 10 and the rising part 2 at the same time. I don't mind.

Then, insert the lower end of the pole 5 into the cylindrical part 3 of the support arm 1, and cap the upper and lower edges of the pole 5 with rubber bushings 9.
A branch line 1 is connected between the locking hole 8 of the locking protrusion 7 and an appropriate location on the roof.
8 is tensioned, the lead-in electric wire 20 from the telephone pole is held by the retainer 19 supported by a suitable locking protrusion 7, and the electric wire 20 is inserted into the pole 5 from the upper end of the pole 5.
The electric wire 20 is pulled out from the lower end and connected to a power meter or the like attached to the house.

In this way, in this invention, the pole 5 is made to protrude from the roof,
Since the lead-in electric wire 20 from the utility pole is held at the upper end of the pole 5, a sufficient standard height for holding the lead-in line can be secured.

Moreover, since the electric wire 20 that has been held back is inserted into the pole 5 and pulled out from the lower end of the pole 5, the electric wire 20
The pole 5 is exposed outside, giving it a clean and beautiful look.

In addition, in this design, when installing on the main building 16, the auxiliary tool 1
0 is used, and auxiliary tools 10 are applied to the two sides of the main building 16 and fixed with bolts, screws, or nails to the side and bottom surfaces of the main building 16, and stainless steel bands 1 are attached to the end sides of the main building 16.
7, there is no fear of cracks occurring in the purlin 16 even when bolts, screws, or nails are inserted into the purlin 16, and furthermore, the support arm 1 is firmly fixed to the purlin 16.

Further, in this invention, as shown in FIGS. 6A and 6B, the support arm 1 is attached to the main building 16 in various ways, and the support arm 1 is shaped like a key by the rising part 2 provided at one end of the support arm 1. In combination with this, the support arm 1 can be attached to the house while avoiding the gables and the like, and the pole 5 can be made to protrude outward from the house.

Note that FIG. 6A shows the same aspect as the above embodiment, and FIG. 6B shows the main building 16.
This is an example in which the support arm 1 is attached by applying the vertical plate 11 of the auxiliary tool 10 to the end surface and applying the horizontal plate 12 to the lower surface of the main building 16.

In addition, the locking protrusion 7 of the pole 5 can be used not only for the retainer 19 and the branch line 18, but also for hooking a worker's lifeline, and two or more lead-in electric wires can be attached to the upper and lower locking protrusions 7. It can also be used for a variety of purposes, such as running power lines to neighboring houses.

Furthermore, the bolt holes 4 in the support arm 1 contribute to reducing the weight of the support arm, and are convenient for locking other members, such as a ground wire.

In addition, if instead of the above embodiment, the structure is such that the space between the rising part 2 and the cylindrical part 3 of the support arm 1 is curved, it will be even easier to attach the support arm 1 to a house while avoiding obstacles such as gables. It's convenient.

Further, the locking protrusion 7 is not limited to the one described above, and may have an appropriate shape.

As described above, this idea is based on an angled pole for connecting electric wires, which can easily secure the standard height by securing the lead-in wires from utility poles, etc. at the top of the pole that protrudes above the roof, and by increasing the height of the retaining point. By removably attaching the auxiliary tool to the support arm, the pole can be supported and fixed on two sides perpendicular to the attachment point of the main house, etc., and therefore it can be firmly supported and fixed.
