Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a horizontal/vertical instrument that accurately measures horizontality and verticality.

A conventional horizontal/vertical level (level) is constructed as shown in FIG.

This has a leveler 2 provided on one side of a rectangular parallelepiped member 1 made of wood, and a verticalizer 3 provided on the other side.

The level device 2 has a liquid 5 sealed in a straight glass tube 4, and the levelness is checked by aligning the position of a bubble 6 formed inside the glass tube 4 with a reference line T drawn on the glass tube 4. ing.

The vertical device 3 is designed to seal a liquid 5 in a curved glass tube 4, and to check the verticality by placing a bubble 6 formed inside the liquid 5 at the bottom of the curved glass tube 4.

However, in the conventional horizontal/vertical device, the horizontal/vertical degree is determined based on the position of the bubble 6 sealed in the glass tube 4, so there is a large error, even if the horizontality is adjusted over a distance of about 5 to 6 meters.
There was an error of several meters at both ends, so it could not be used to check accurate levelness.

Similarly, when checking verticality, there is a large error, so it was usually done visually using a ``plumb swing'' with a weight suspended from the bottom end of a string.

In addition, conventional horizontal and vertical meters do not have angle display scales, so they cannot measure the angle of sloped parts.When adjusting the slope of a roof or stairs, a protractor or similar device is used to measure the slope. The error was large.

The present invention improves the above-mentioned conventional drawbacks and provides a horizontal/vertical instrument that can accurately check the horizontal/vertical degree and also easily measure the inclination angle.

Embodiments of the present invention will be described in detail below with reference to the drawings.

2 to 4 show an embodiment of the present invention. In the figures, 8 is a main body case 8 formed in the shape of a rectangular parallelepiped with a hollow interior. A window 9 is formed in each, and an L-shaped transparent cover 10 is attached to the window 9.

The inside of the main body case 8 has a level 2 as shown in FIG.
and a vertical device 3 are respectively attached.

The level 2 includes a link mechanism 11, a weight 12A attached to one end of the link mechanism 11, an enlarged angle indicator 13 attached to the other end of the link mechanism 11, and a weight 12B at one end.
Angle pointer 1 is rotatably attached to the shaft 14.
5, and a protractor 16 disposed between the angle pointer 15 and the enlarged angle pointer 13.

The link mechanism 11 has five connecting rods 17a.

17b, 17. 17d, 1γ.

These are movably connected with a pin 18 in a substantially S-shape.

Connecting rod 1γ8, 1γ. , 17e is the axis 1 which serves as a rotational fulcrum.
4, and its shaft 14 is offset from its center so that t<r=.

Reference numeral 19 denotes a support frame for the protractor 16, and a connecting rod 118 with an enlarged angle pointer 13 attached is arranged on the back side of this support frame 16.
Support rod 20 with angle pointer 15 attached to the front side of protractor 16
are arranged, and these are coaxially supported by a shaft 14.

The vertical device 3 has almost the same structure as the level device 2, but the link mechanism 11 has a different structure.

This link mechanism 11 has three connecting rods 21a.

21b and 21o are connected by a pin 18, and each is rotatably supported by a shaft 14 which serves as a rotational fulcrum, and the diagonal shaft 14 is provided with its center shifted so as to be t(L). There is.

In addition, the connecting rod 21a. The connecting portions 21b and 21c by the pins 18 are formed in a long hole shape, and the connecting rods 21a and 21
b.

21c can rotate freely.

Next, the operation of the horizontal/vertical device having the above structure will be explained.

When checking the levelness, arrange them horizontally as shown in FIGS. 2 and 3.

When the object to be measured is tilted, the weight 12A of the leveler 2 is always vertical, so the connecting rod 1γa rotates in the direction of the arrow by an angle θ.

This rotation of the connecting rod 17a is transmitted to the enlarged angle pointer 13 by the link mechanism 11 as rotation and movement in the direction of the arrow. Since the shaft 14, which is the auxiliary fulcrum of the 178, is mounted offset from the center so that /, expanded,
This results in a large rotation to an angle θ2.

Therefore, when the enlarged angle pointer 13 is located at the O scale 22 of the protractor 16, it is in an accurate horizontal state, and even if there is a slight inclination, the enlarged angle pointer 13 will be greatly assisted. Compared to those that check the levelness based on position, it can determine the level with higher accuracy.

Since the angle pointer 15 has a weight 12B attached to the support rod 20, it rotates according to the inclination angle θ. Can be read.

In addition, since the enlarged angle pointer 13, the angle pointer 15, and the protractor 16 are attached coaxially, the enlarged angle pointer 13
When the angle pointer 15 and the O scale 22 of the protractor 16 match, the horizontal state is reached, and the horizontality can be checked more easily and accurately than in the conventional case.

To check the levelness in a very low place, as shown in FIG. By aligning the reference point scale 22 on the same straight line, the levelness can be easily and accurately checked.

When checking the perpendicularity of the met, the enlarged angle pointer 13 can be aligned with the reference point scale 22 of the protractor 1600 by the same action as described above by starting from the state shown in FIGS. 2 and 3 and using it vertically. This allows you to easily and accurately check the verticality.

rj The link mechanism 11 of the leveler 2 has three connecting rods 17a and 17o whose pivot points are offset from the center.

1γ8, the bent vertical device 3 forms the link mechanism 11 by combining three connecting rods 21a, 21b21c with the pivot point shifted from the center, so the magnification is large and the angle is The deflection directions of the pointer 15 and the enlarged angle pointer 13 are the same, and misreading of the tilt direction can be prevented.

Weights 12A and 12C attached to the link mechanism 11 of the enlarged angle pointer 13 and weight 12B attached to the angle pointer 15
, 12D, the weight of each can be changed, and in particular, by increasing the weight of the link mechanism 11, the movement can be instructed quickly and accurately.

Further, both the enlarged angle pointer 13 and the angle pointer 15 may be arranged on the front side or the back side of the protractor 16.

In the above embodiment, the main body case 8 includes a level device 2 and a vertical device 3.
Although shown is a case in which both are attached together, they may be attached separately.

As explained above, according to the horizontal vertical device according to the present invention, the link mechanism applying the lever principle and the weight are combined, and the enlarged angle pointer is attached to show the enlarged angle larger than the actual inclination angle. Even a slight inclination can be detected, and accurate horizontal and vertical degrees can be easily checked, and the upward tilt angle can also be easily read, and the angle pointer and magnified angle pointer swing in the same direction. There is no misreading of the direction of inclination, and this has extremely high practical value.
