Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card type simple level.

[0002]

2. Description of the Related Art Recently, the use of a spirit level in the home is increasing due to popularization of cameras and video cameras, installation of electric refrigerators, do-it-yourself carpenters and the like. Along with this, small levelers are also available. However, these small levelers are simply small and easily lost, and they are inconvenient to carry around when put in a pocket of clothes, etc. , Or the angle of inclination could not be investigated, or the shape was various.

[0003]

SUMMARY OF THE INVENTION In view of the above situation, it is an object of the present invention to provide an inexpensive and convenient card-type simple leveling device which can easily see the horizontal, vertical and tilt angles. .

[0004]

In order to achieve the above object, the spirit level according to the present invention is provided with a flat hollow portion 2 on the upper surface of a sheet 1, and a liquid 3 is sealed in the flat hollow portion 2. One small bubble 4 is provided inside the flat hollow portion 2 so that the lower surface of the sheet 1 becomes horizontal when the bubble 4 is located at the central portion 5 of the flat hollow portion 2.
Has a circular outer peripheral line, and an angle graduation 6 centered on the center point 5 is provided around the outer rim of the circle. When the bubble 4 is positioned at the zero angle of the angle graduation 6, one of Two or more sides are made horizontal, and the outer peripheral edge of the flat hollow portion 2 is circular, and the upper surface of the sheet 1 is located on a line on a circle centered on the central portion 5 of the flat hollow portion 2. A circular annular hollow portion 7 is provided, a liquid 8 is enclosed in the annular hollow portion 7, a small bubble 9 is provided therein, and an angle scale 10 is provided around the outer peripheral edge of the annular hollow portion 7. One or more sides of the outer peripheral edge of the seat 1 are made horizontal when the air bubbles 9 are positioned at the zero angle of the angle scale 10, and the seat 1 is embodied as a car, flower, animal or the like. It has a shape.

[0005]

The first embodiment shown in FIGS. 1 and 2 constitutes a sheet 1 by laminating and sticking a transparent plastic film 12 on the upper surface of a plastic thin plate 11 of a telephone card size. The liquid 3 is sealed between the central part of the transparent plastic film 12 and the plastic thin plate 11 and a small air bubble 4 is contained therein.
It is provided with a flat hollow portion 2 having a central portion 5 with a mark, and is dedicated to a spirit level.

The second embodiment shown in FIGS. 3 to 5 is the first embodiment described above.
A level body main body 13 having a circular flat hollow portion 2 in the center is constructed in the same manner as the dedicated level spirit of the embodiment, and a central portion 5 is provided around the outer peripheral edge of the flat hollow portion 2 of the level body 5.
An angle scale 6 centered on the
Is such that one or two or more sides of the outer peripheral edge of the sheet 1 are horizontal when is positioned at the zero angle of the angle scale 6.

The third embodiment shown in FIGS. 6 to 8 is the first embodiment described above.
A level body main body 14 having a circular flat hollow portion 2 in the center is constructed in the same manner as the dedicated level spirit of the embodiment, and the central portion 5 of the flat hollow portion 2 is centered on the upper surface of the level body body 14. A circular annular hollow portion 7 for enclosing a liquid 8 having a small bubble 9 therein is provided at a position on the circle line, and an angular scale 1 is provided around the outer peripheral edge of the annular hollow portion 7.
0 is provided so that one or more sides of the outer peripheral edge of the sheet 1 become horizontal when the bubble 9 is located at the zero angle of the angle scale 10.

In the fourth embodiment shown in FIG. 9, the seat 1 has a concrete shape of a car, and the rest of the construction is the same as that of the first embodiment.

In the present invention, a part or the whole of the sheet is made of paper, the sheet is made of a rubber magnet or a plastic magnet, and a pressure-sensitive adhesive layer and a release paper for covering the same layer are provided on the back surface of the sheet. Or, by providing male and female surface fasteners, it can be attached anywhere.

[0010]

In the electronic level according to claim 1, when the sheet 1 is placed on the measuring surface 16 and the bubble 4 coincides with the central portion 5 of the flat hollow portion 2, the measuring surface 15 is horizontal. Some things are known to be non-horizontal when out of alignment.

A level according to claim 2 is the above level 1
It is of course possible to know whether or not it is horizontal by using it in the same way as the electronic level relating to the above. However, if it is not horizontal, as shown in FIG. When contacting the measurement surface 18, the bubbles 4 correspond to the angle scale 6, and the inclination angle can be known from this.

[0012] The spirit level according to claim 3 is the above level 1
Alternatively, it is of course possible to know whether or not the level is horizontal by using it in the same way as the spirit level according to 2, and it is possible to know the inclination angle, but the bubble 3 existing in the flat hollow portion 2 in the center can be detected from the central portion 5. In the case of a slight deviation that cannot be easily discerned by eye, the bubbles 9 present in the annular hollow portion 7 will stop facing the frequency of the angular scale 10, and thus the slight deviation will be discriminated by the frequency. be able to.

The spirit level according to claim 4 is the above level 1
It is of course possible to know whether or not it is horizontal by using it in the same way as the electronic level related to, but the seat 1 is shaped like a car, a flower, or an animal. It is something that can be aroused by the interest.

[0014]

Since the spirit level according to the present invention has the above-mentioned structure and is thin like a card, it is advantageous for carrying, storing, packaging, etc., and it is desired to know the horizontal, vertical and inclination angles. Sometimes it is easy to know by using this, and as can be seen from the above embodiment, it can be provided easily and inexpensively. Further, since the structure is simple and the shape is not narrowed down, there is an advantage that the size and shape can be freely set and a large commercial space can be taken as a sales promotion item.
