Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a level for measuring the verticality of a wall surface as a measurement surface, for example. 2. Description of the Related Art In verticality measurement using a bubble tube level, for example, a rectangular shape in which a reference surface that abuts a vertical surface such as a wall surface is provided on the bottom surface. A window hole is provided on the side of the container, and the bubble tube level 3 provided on the mounting body is mounted in the container so as to be visible from the window hole. In addition, the verticality of the vertical surface is measured by observing the bubble position of the bubble tube level 3 that is horizontally arranged in the horizontal direction that is the normal direction of the vertical surface. However, measurement surfaces (elevated surfaces such as wall surfaces)
The measurer who is directly facing the instrument, after placing the container on the vertical surface, has to look into the container from the side because the bubble tube level 3 is provided on the side of the container. Don't be. Accordingly, it cannot be said that the work efficiency is poor because the measurement with the bubble tube level cannot be performed with the posture facing the elevation. Moreover, on the upper surface of such a container,
A horizontal bubble tube level for measuring the level of the horizontal plane is often provided. Therefore, when measuring the level, the bubble tube level is viewed from the top as it is. However, when measuring the verticality, the bubble level should be viewed from the side of the body. You will have to change your view of the body. In the present invention, the levelness is seen from the upper surface of the body.
The verticality is different from this, breaking the fixed idea that the side of the body must be looked into, and using the mirror part, it can be measured even from the top of the body, and the body is placed on the elevation that becomes the measurement surface. This is an epoch-making level in which the work efficiency can be greatly improved by allowing you to visually measure the bubble tube level without looking into it from the side while keeping the posture facing the elevation. The purpose is to provide a vessel. The gist of the present invention will be described with reference to the accompanying drawings. A container body 2 provided with a reference surface 1 that contacts the measurement surface
Is provided with a bubble tube level 3 and a wall surface as a measurement surface.
When the reference surface 1 is brought into contact with the vertical surface, the bubble tube level
3 is arranged in the horizontal direction, and the air
The perpendicularity of the measurement surface according to the position of the bubble in the bubble tube level 3
The bubble tube level device 3 is fitted to a resin-molded mounting body 10 and is removed.
By mounting the Tsuketai 10 in device body 2, the device body 2 of the bubble tube type level gauge 3 from the window hole 11 provided on one surface 5 is configured to be visible, the resin molding of the mounting member 10 The other surface 6 different from the one surface 5 from the side of the bubble tube level 3
The light guide portion 7 communicating with the provided course of the slope of the light guide section 7
A mirror in which the mirror part 8 is provided on the inner surface part and the bubble tube level 3 reflected by the mirror part 8 can be visually recognized from the window hole 12 provided in the other surface 6 of the container body 2.
It relates to a spirit level characterized by constituting the visual recognition mechanism 9 . BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention considered to be the best (how to carry out the invention) will be briefly described with reference to the drawings showing the effects thereof. An instrument body 2 provided with a reference surface 1 which is in contact with the measurement surface
Is provided with a bubble tube level 3 and a wall surface as a measurement surface.
When the reference surface 1 is brought into contact with the vertical surface, the bubble tube level
3 is arranged horizontally and the bubbles are installed horizontally in the horizontal direction.
Measure the perpendicularity of the measurement surface by the position of the bubble in the tube level 3
The bubble tube level 3 is molded with resin.
Fitted to the mounting member 10, mounting the mounting member 10 in Utsuwatai the 2
Then, the air is released from the window hole 11 provided on the one surface 5 of the container body 2.
The bubble tube level 3 can be visually recognized. By the resin molding of the mounting body 10 , the bubbles are
From the side of the tube level 3 to the other surface 6 different from the one surface 5
A light guide portion 7 that is in communication is formed, and a slope in the middle of the light guide portion 7
When the mirror 8 is provided on the inner surface, the container 2
From the window hole 12 provided on the other surface 6, the mirror portion 8
Mirror viewing that allows you to see the bubble tube level 3
The mechanism is configured, and such a mounting body 10 is manufactured.
Easy to produce and mass production. The preferred embodiments of the present invention will be described with reference to the drawings. In this embodiment, a hollow rectangular container 2 having a reference surface 1 abutting on a measurement surface (an elevation surface such as a wall surface) provided on the bottom surface.
The bubble tube level 3 is provided so as to be visible from the side surface 5 of the container body 2, and when the reference surface 1 of the bottom surface of the container body 2 is brought into contact with the vertical surface as the measurement surface, the bubble tube level The vessel 3 is arranged in the horizontal direction which is the normal direction of the vertical surface, and the verticality of the measurement surface can be measured by the position of the bubble 4 of the bubble tube level 3 placed horizontally in the horizontal direction. The light guide unit 7 is configured so that the bubble tube level 3 can be visually reflected from the upper surface 6 of the container 2 which is the opposite surface of the bottom of the container 1 provided with the reference surface 1. A mirror visualizing mechanism 9 including a mirror unit 8 is provided. Specifically, a hollow portion extending from the side of the bubble tube type level 3 embedded in the vessel body 2 to the upper surface 6 of the vessel body 2 is provided, and the light guide portion 7 is placed inside the vessel body 2. The bubble tube level 3 can be seen from the side surface 5 of the vessel body 2 and the upper surface 6 of the vessel body 2. The mirror visualizing mechanism 9 is configured so that it can be visually recognized by the light guide portion 7 and the mirror portion 8. More specifically, in this embodiment,
A transparent resin material 3A in which the bubble tube level 3 is embedded is fitted into a fitting portion 10A of a mounting body 10, and the mounting body 10 is attached to the container 2
The bubble tube level 3 can be seen through a circular window hole 11 provided on the side surface 5 of the container 2 by being mounted inside, and the bubble tube level 3 is attached to the mounting body 10. Forming a cavity communicating with the upper surface 6 of the vessel 2 from the side of the light guide 7
The plate-like mirror part 8 is provided on the inclined inner surface part in the middle of the light guide part 7 and is reflected by the mirror part 8 from the rectangular window hole 12 provided in the upper surface 6 of the container 2. The bubble tube type level 3 is configured to be visible. Therefore, in this embodiment, the bubble tube type level 3
By providing the light guide part 7 and the mirror part 8 on the mounting body 10 provided with the mirror, the mirror visualizing mechanism 9 can be configured, and the manufacture is easy and the practicality is excellent. In particular, in this embodiment, the light guide 7 is formed by resin molding of the mounting body 10 and the mirror portion 8 only needs to be provided on the inner surface of the light guide 7, so that it is extremely practical. Since the present invention is constructed as described above, the mirror portion can be used to measure, for example, from the upper surface of the vessel, and therefore the vessel is placed on the vertical surface as the measurement surface. It is possible to measure by directly viewing the bubble tube level without looking into from the side while keeping the posture facing the surface, greatly improving work efficiency, easy to manufacture, and excellent in mass production. It will be an extremely practical level.
