JPH07128054A - Apparatus for measuring horizontalness of object - Google Patents

Abstract

PURPOSE:To allow easy measurement of horizontalness of a long material or between two points by filling a soft tubular body part with water, applying the opposite ends of a detector enclosed (opposite ends of the tubular body are opened) by flexible movable parts to measuring parts, and then reading the movement of the movable parts on graduations. CONSTITUTION:One graduation 4 on the body part 1 is applied, at the central part thereof, to a reference point of an object to be leveled. The other end of the graduation 4 is shifted and the detector (body part 1) is secured at a position where the upper part of the movable part 3 is aligned, at the opposite ends thereof, with the center of the graduation. When the object to be leveled is shifted, at the other end thereof, to the center of the latter graduation 4, the object is leveled. Horizontalness of the object is determined by applying the graduations 4 at the opposite ends to the object, reading both graduations, i.e., the shifted state of the upper part of both movable parts 3, and then determining the difference between.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple and accurate reading of the horizontality of a long object or two points apart from each other.

[0002]

2. Description of the Related Art Conventional levelers have a measuring device for short objects, and cannot measure points apart from each other.

[0003]

In the conventional spirit level, an error is large when a long object is measured, and an expensive and large-scale device is required to measure a distant point.

[0004]

In order to achieve the above object, the horizontality measuring device according to the present invention has a soft tubular shape and is composed of a movable portion and a graduation portion at both end portions.

[0005]

[Operation] When both ends are brought into contact with the measurement point, the movable part moves and changes.

[0006]

EXAMPLES Examples will be described with reference to the drawings. Apply one end of Drawing 4 to the center of the scale of 4 at the reference point of the object to be horizontal. The other end of 4 is moved, and the device is fixed at the position where the upper part of 3 coincides with the center of the scale. If you move the other end of the object you want to be horizontal to the center of the latter's 4 scale, the object becomes horizontal.

The levelness of the object can be confirmed by applying both ends of 4 to the object and reading the scale to know the levelness.

[0008]

Since the present invention is configured as described above, it has the following effects.

Due to the simple structure, there are few failures.

The levelness of the object or the measuring point can be easily known.
