【考案の詳細な説明】
本考案は電柱に電線やケーブル(以下電線類と
称する)を架渉した場合の取付角度を測定する角
度測定器である。[Detailed description of the invention] This invention is an angle measuring device that measures the installation angle when an electric wire or cable (hereinafter referred to as electric wires) is strung on a utility pole.
電柱に電線類を架渉した場合でそのルートがカ
ーブになつた場合には、カーブになつた電柱に対

て異なつてくる、即ちカーブがきつければ太くて
強い支線が必要になる。 When wires are strung across utility poles and the route becomes a curve, a branch wire is attached to the curved utility pole toward the outside of the curve to prevent the pole from falling, but the strength of this branch wire is Depends on the number and size of wires to be spanned and the degree of curve; in other words, if the wire is curved, a thicker and stronger branch line will be needed.

た。 The method of measuring the size of this curve is to draw an isosceles triangle of several meters on the ground along the conventional route with the utility pole as the apex, and calculate the triangular triangular number from the distance between the midpoint of the base and the utility pole. was used to find the angle. For this reason, it has been desired to have a method for measuring curves that is simple and time consuming.

力を発することができる。 The present invention was devised in an attempt to solve this drawback, and the angle scale 2 from 0 degrees to 180 degrees is displayed on the upper surface of the peripheral edge of a semicircular mirror 1, and the semicircular mirror 1 is displayed at the center position of the scale. 1 has a hole 3, a core rod 4 is rotatably inserted into the hole 3, a measuring device main body 7 consisting of a pointer 5 and a knob 6 fixed to the core rod, and a transparent top lid covering the measuring device main body. This is an angle measuring instrument consisting of a case 8 equipped with a case 8, which can be sufficiently effective for work such as adding electric wires to an existing route or checking the strength of branch lines on an existing route.
以下図面によつて説明する。 This will be explained below with reference to the drawings.

の上部から見る事ができる。 Figure 1 is a front view of the angle measuring instrument according to the present invention.
The main body of the measuring instrument is covered by a case, but since the top cover is transparent, the semicircular mirror 1, the angle scale 2 and the pointer 5 displayed on the upper surface of the periphery of the mirror can be seen from the top of the measuring instrument.

This shows the relationship between the two, and when the knob 6 is rotated, the pointer 5 is also rotated at the same time.

5の指す角度目盛りを読みとればよい。 FIG. 3 shows how the angle measuring device according to the present invention is used to perform measurements. First, the measuring device is pressed horizontally and at a nearly right angle to the side of the utility pole to be measured. Then, the head of the utility pole and the electric wires attached to it are reflected in the semicircular mirror 1. Next, make sure that the head of the telephone pole is reflected at the position of the core rod of the mirror, and that the image of either the left or right side of the electric wires attached to the pole is at 0 degrees on the angle scale of the measuring instrument.
Adjust the direction of the measuring device so that it overlaps the line connecting 180 degrees (hereinafter referred to as the baseline). Next, turn the knob 6 to overlap the pointer 5 on the image of the other electric wire that was not aligned with the base line. The above is the measurement procedure, and the angle formed between the position of the pointer 5 and the base line at this time is the installation angle of the electric wires strung across the utility pole, and therefore, it is sufficient to read the angle scale indicated by the pointer 5.

帯にもいたつて便利である。 As described above, the present invention reflects the electric wires strung in the air in a mirror directly below it, and the installation angle is directly read from the angle scale displayed on the mirror, so measurement does not take much time or effort, and there is no error. few. Furthermore, the angle measuring device according to the present invention is small enough to be stored in a pocket, making it convenient to carry.
