Abstract

PURPOSE:To facilitate handling and to achieve a quick stationary stabilization state by mounting a plurality of grounding resistors which virtually do not prevent the suspension of a plumb bob body to a member for mounting the plumb bob body. CONSTITUTION:A fixing screw 12 through a peripheral wall is mounted to the peripheral wall part of a cylindrical part 11 where an upper projecting part P1 of a body P can be inserted in a member 1 for mounting the plumb bob body P and at the same time a plane table body 13 for mounting a grounding resistor protruding from a maximum expansion part P2 of the body P is formed at the outer periphery of the lower part of the cylindrical part 11. A lower bent piece 13a for mounting grounding resistor which is shorter than a body is formed in one piece with the flat-plate body 13 at the lower edge of the plane table body 13. A grounding resistor 2 is mounted to the lower edge of the bent piece 13a. Then, in the body P, the cylindrical part 11 of a stationary tool is covered and inserted into an upper protruding part P1 and is mounted and fixed by a fixing screw 12, thus quickly stopping and stabilizing the plumb bob.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plumb bob and a plumb bob.

[0002]

2. Description of the Related Art A plumb bob is used to check a vertical state, to give a red ink, or to give a vertical ink by hanging it from the upper part. Was simply composed of a cone.

Therefore, the conventional plumb bob is easily affected by pendulum motion, wind, etc., so that it does not stand still easily and it takes a long time for vertical confirmation.

[0004]

Therefore, as a result of various studies, the present inventor has carried out various studies for the purpose of solving such a conventional problem and providing a plumb bob which becomes a natural stationary state in an extremely short time. The present invention has been completed.

[0005]

That is, the first feature of the present invention is that a plurality of grounding resistors that do not substantially hinder the suspended body of the plumb bob body are attached to the plumb bob body mounting member. It is a stationary device for plumbing,
A second aspect of the present invention is a plumb bob, which is characterized in that a plurality of grounding resistors are attached to the plumb bob body so as not to substantially interfere with the suspended state of the main body.

In the present invention, the grounding resistor may be of any kind as long as it does not substantially hinder the body from being suspended and suspended. For example, a chain,
A preferable example is a string, a brush, a spring, a bendable iron ball or a rubber ball connecting sphere, or a combination of these, and the middle chain hangs down and exerts an excellent static action without disturbing the suspended state of the main body. At the same time, a particularly good result is given in that the length can be freely adjusted by appropriately selecting and locking the wheel portion.

It is desirable that a plurality of grounding resistors, preferably 2 to 4, and especially 3 are attached and hung down at equal intervals.

In the first aspect of the present invention, as the lower swing body mounting member, a fixing screw that penetrates the peripheral wall is provided on the peripheral wall portion of the upper protrusion inserting cylinder portion of the lower swing body, and It is preferable to use a flat body for attaching the grounding resistor or an arm rod projecting from the maximum bulging portion of the swinging main body on the outer periphery of the lower portion of the portion.

Here, it is stable that the ground resistor mounting flat plate or the arm rod is integrally molded with the lower bent portion for mounting the ground resistor at the outer edge thereof in correspondence with the number of ground resistors to be mounted. It is advantageous in obtaining a static effect.

Further, in the second aspect of the present invention, the grounding resistor may be directly attached to and fixed to the body.
It is simple and effective to attach the above-described down swing stationary device according to the first aspect of the present invention to the down swing body detachably.

[0011]

According to the present invention, if the plumb bob body is suspended according to a conventional method, the grounding resistor also hangs down from the body, and its lower end contacts the ground. In addition to stabilizing the movement in a very short period of time, there is no hindrance to the suspension of the main body.

[0012]

The present invention will be further described with reference to the drawings showing the following embodiments.

First, a description will be given of the down swinging stationary device of the present invention. As shown in FIGS.
With the attachment member, a total of three fixing screws 12 penetrating the peripheral wall are attached to the peripheral wall portion of the cylindrical portion 11 into which the upper protruding portion P1 of the plumb bob body P can be inserted from three sides.
On the outer periphery of the lower portion of the cylindrical portion 11, a flat plate body 13 for attaching a grounding resistor, which projects from the maximum bulging portion P2 of the swinging main body P, is formed. Further, on the outer edge of the flat plate member 13, three lower bent portions 13a for attaching a grounding resistor, which are shorter than the lower swing body P, are integrally formed with the flat plate member 13 at equal intervals.

Reference numeral 2 denotes a grounding resistor, which is each of the lower bent portion pieces 1 described above.
A total of three are attached to the lower end of 3a. Here, as the ground resistor, as shown in FIGS. 1, 3 and 5 (1),
In the example of (3), a chain; in the example of FIG. 5 (2), a chain in which a rubber ball is connected to the lower end; in the example of FIG. 5 (4), a spring; Brushes are used in the examples.

Next, the plumb bob of the present invention will be described. As shown in FIG. 1, the plumb bob main body P is inserted into the upper protrusion P1 of the tubular portion 11 of the stationary tool shown in FIGS. And is fixedly attached by a fixing screw.

[0016]

According to the present invention, the stationary state can be achieved in a short period of time in which the handling is easy and the swinging motion is extremely short. Also, since the influence of wind etc. is less than before,
The weight of the plumb bob body can make it lighter.
