Abstract

PURPOSE:To associate the level and angle gauge and to reduce the size and weight so that they can be put in a pocket by indicating the angle between the reference surface of a main body and a subordinate plate in the form of the movement distance of a connecting line which connects an angle gauge main body and the subordinate plate by using the connecting line. CONSTITUTION:The level 2 is fixed to one end of the angle gauge main body 1 and the reverse surface of the main body 1 which is parallel to the level 2 is used as the reference surface. Further, the line 7 for connecting the main body 1 and subordinate plate 4 is connected to nearby the center part of the subordinate plate 4. Further, a pointer 11 is set at a position meeting the 0 point of the angle scale of the connecting line 7 on an angle scale plate 10. Further, the angle (a) between the reference surface 3 and subordinate plate 4 is read directly on the angle scale board 10 on the same surface with the level 2. Then the reverse surface of the subordinate plate 4 is brought into contact with an object surface and the one end of the main body 1 is lifted to hold the level 2 horizontal, so that the angle to the horizon is indicated on the scale board 10. Thus, the level 2 and angle gauge are associated with each other to reduce the size and weight.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a portable spirit level with a goniometer that is small and light.

``Prior Art'' Many spirit levels that can measure angles with respect to the horizontal have been used in the past, but there have been few that are relatively large, easy to carry, and convenient to use.

``Problems to be Solved by the Invention'' The present invention attempts to solve these problems by linking a level and an angle meter, making it small and light enough to fit into a bog, and making it more convenient to carry. This is what I am trying to do.

"Means for solving the problem" In the invention of claim 1, the angle (a
) is intended to be replaced with the distance traveled by the line.

In the invention of claim 2, when a plurality of spring mold members are connected and one end thereof approaches the end of the capacity, the connected body of the members is constructed so as to form a semicircle, and this ? 1%1
A transparent flexible resin pipe for a spirit level is passed through the member, and when in use it forms a semicircle, and when not in use it is stretched out into a rod shape to be stored and carried.

"Function" In claim 1, after first bringing the lower surface of the sub-plate into close contact with the target surface, one end of the main body of angle a1 is lifted and the spirit level is leveled, so that the angle 1'7 relative to the water level becomes the scale. be instructed.

In claim 2, first, the slide side of the connecting body of the erasable part t (t) is brought closer to the fixed side, the connecting body of the fan-shaped member is made into a semicircle, and the lower surface of the holder is brought into close contact with the object 1-. By doing so, you can read the angle of the scale based on the position of the bubble on the spirit level.

“Example IJ An embodiment of claim 1 will be described with reference to the drawings.

1 is a plan view, FIG. 2 is a cross-sectional view taken along line 8 in FIG. 1, and FIG. 3 is a left side view.

A sub-W for angle measurement, in which a level (2) is fixed to one end of the rectangular angle meter body (1), and the lower surface of the body (1) parallel to the level is the reference plane (3), (,4) At one end of the level fs side of the −fi reference plane, insert the hinge (5) and place the #1 axis (6) on the same plane as the reference plane to join the 0 body ( 1) and the sub-plate (
Tie it near the center of 4). An elastic body (8) such as rubber for tension is tied to the other end of the connecting wire. This elastic body is made of two thread-like rubber or the like so that they do not cross each other when intersecting the connecting line inside the book 14, so that the connecting line can pass between them. Make it.

Pass the ends of the connecting wires on the elastic body side through the holes (14) and (15) provided on the bottom and top surfaces of the main body (1).

Pass over the angle dial (10) provided on the top surface of the main body, insert into the hole (16) in the main body, and insert the pulley (1) provided inside the main body.
7) to the end (18) on the level side.

A pointer (11) is set on the connecting line (7) on the angle scale (10) at a position that matches the zero point of the angle scale.

For the angle scale, the pointer position when the reference surface and sub-plate are in close contact is 0, and the maximum angle between the sub-plate and reference surface is the maximum scale.
A scale is engraved between the two, corresponding to the angle.

It has the following configuration, and the angle 1t (a
) is a portable spirit level that can be read directly from the angle scale on the same surface as the spirit level.

[Example 2J An embodiment of claim 2 will be explained based on the drawings.

Figure 4 is a front view when in use, Figure 5 is a top view when not in use,
Figure 6 is a front view when not in use.

A clear part t (9) with a side plate (8) of yilIJTj inscribed with an angle scale consisting of 9 or an integral multiple of 9.
Build a connecting body (12) whose outer periphery is connected by a bendable transparent connecting band (6), and slide the fixed plate (2) on one side of the store and the other end! When (5) are brought close to each other, the side parts (12) of the fan-shaped side plates are closely spaced with each other to form a connecting body (12) of the wave-shaped members.

A bubble is created in a transparent flexible resin pipe (13) for a spirit level, which has a length approximately equal to the circumference of the semicircular shape of the above-mentioned connecting body (12), and a transparent liquid is poured into the pipe (13). This transparent pipe (13), which is enclosed and its both ends are closed, is passed through the connecting body (12) of the groove-shaped member, and both ends of the pipe are connected to both end face plates (15), (16) of the connecting body (12). Fixed to. One end of a connecting body (12) of the ray-shaped member is fixed to a fixing plate (2) at the end of a rectangular plate-shaped base (1) via a hinge (3). Also, attach the slide plate 5) to the other end of the connecting body via fi'# (4), so that the end of the connecting body slides over the rectangular plate-shaped base (1). Make it possible to do it.

With the above structure, when in use, one end of the connecting body is placed close to the edge of the pond, making the connecting body semicircular, and used as a level with an angle gauge, and when not in use, the slide side is stretched out and the connecting body is shaped like a rod, with a presser frame at the end. (17) is moved to near the center of the base to make it convenient to carry.A portable level with an angle gauge.

"Effects of the Invention" 1) Effects of Claims 1) Small and lightweight, convenient to carry. 2) If you place the subplate tightly on the object and hold one end of the spirit level, you can read the angle directly.

3) Depending on the purpose, the angle measurement range can be selected by selecting the position for attaching the connecting line connecting the sub-plate and the main body to the sub-plate. In other words, usually around 0100 degrees is practical, but By moving the connection position with the secondary plate closer to the hinge side, the range can be set to 0180 degrees, although the accuracy will decrease slightly.
By placing the connection line and sub-plate close to the free end of the sub-plate, it is possible to accurately measure angles within a small range. 4) Can also be used as a normal angle meter.

2. Effects of Claim 2 l) Small and lightweight and portable: I) Convenient. 2) If the reference plane is brought into close contact with the opposite object, the angle can be adjusted to 1π depending on the position of the bubble. 3) Level 2: Since there is no need to touch the plane, you can change the direction freely and easily know the angle of inclination of the plane and the direction of inclination at the same time.

4) By aligning the () points of a spirit level inside a moving object such as a car, the angle of inclination for climbing and descending can be determined.
