はいずれも全て一直線上に並ぶからである。The weight device of the present invention is used by connecting a hanging string that is wrapped around a support and hanging down to a fixture, and the weight device of the present invention is stopped from swinging by placing a finger on the swinging weight device of the present invention.
Immediately, visually through the transparent cylinder, gently guide the tip of the medium weight with your fingers so that it lines up with the tip of the medium weight, and when it lines up with the tip of the medium weight, point it downward. The direction in which the downward cusp of the body points is the vertical direction. This is because the direction in which the stationary point of the medium weight points is on a vertical line, and the center axis of the medium weight passing through the hanging string and the point, as well as the upward and downward points, are all aligned. This is because they line up on a line.

In the figure, reference numeral 1 indicates a transparent hollow cylinder made of synthetic resin, and an upper weight 2 and a lower weight 3 made of metal such as brass are screwed into the upper and lower openings of this cylinder 1, respectively. It is fitted. The upper weight 2 has a hanging string 5 from the support 4 on its upper surface.
A fitting 6 is provided for connecting the two (see FIG. 2), and the fitting is positioned such that the hanging string 5 from the support 4 is on an extension of the central axis of the cylinder 1. A bullet-shaped intermediate weight 8 having a conical point 7 facing downward is swingably suspended from the lower surface of the upper weight 2 via an intermediate thread 9, and its hanging position is such that the cylinder 1 is in an upright position. When the state is
The central axis of the intermediate weight 8 hanging from the intermediate thread 9 is arranged to coincide with the central axis of the cylinder 1. Therefore, the pointed end 7 at that time also coincides with the central axis of the cylinder 1. Both ends of the intermediate thread 9 are attached to the lower surface of the upper weight 2 and the upper surface of the intermediate weight 8 by means of fasteners 10.11.

な間隙を保って対向配置している。The lower weight 3 includes a conical upper indicator 13 having an upward pointed part 2 protruding into the cylinder 1, and an inverted conical lower indicator having a downward pointed part 14 protruding outside the cylinder 1. It consists of 15 bodies. Both the upward pointed head 12 and the downward pointed head 14 are disposed at positions passing on the central axis of the cylinder 1, and the upward pointed head 12 of them is located above the pointed end 7 of the medium weight. They are placed facing each other with a small gap between them.

るための操作を直ちに行なうことができる。That is, the plumb-down weight device of the present invention has a double structure in which another medium weight is suspended in a liquid with low viscosity inside a weight with a transparent circumferential side, and the hanging line and the tip are suspended inside the weight. Since the center axis of the intermediate weight passing through the center line, and the upward and downward pointed heads are arranged so that they can be lined up in a straight line, the weight device of the present invention can be restrained from swinging by placing your fingers on it. The vertical direction can be reliably determined by visually confirming and guiding the upward pointed head so that it is aligned with the pointed end of the medium weight pointing in the vertical direction. Furthermore, if you stop the weight device of the present invention from shaking by placing your finger on it, the middle weight will quickly come to a standstill due to the action of the low-viscosity liquid, so you can immediately perform the operation to determine the vertical direction. I can do it.
従って、迅速且つ容易に垂直方向の測定ができ、しかも
視覚で確認しながら測定できるので正確な垂直方向を導
