Description

[Detailed description of the invention] (Industrial application field) Regarding the improvement of inclinometers, the technical contents described in this specification are particularly focused on the improvement of inclinometers used in civil engineering, architecture, etc. The purpose of the present invention is to provide the results of development regarding an inclinometer that can easily and accurately measure inclination angles.

(Prior Art) Conventionally, inclinometers used to measure inclination angles with respect to the vertical and horizontal in civil engineering, construction, and other construction work or inspection of constructed parts have been used to measure inclinometers that are perpendicular to a single measurement reference plane provided on a base. It has a built-in structure that rotatably holds a rotor with a level indicating vial in the orientation, and when measuring the inclination angle, the measurement reference surface of the base is placed on the measurement surface and the vial is rotated. It was common to move the bubble in a straight line, and read the angle when the bubble in the vial became horizontal using an angle display scale plate provided on the base.

Reference may be made to, for example, JP-A-55-147610 and JP-A-56-40706 as documents.

By the way, the above-mentioned inclinometer has a structure that requires holding the inclinometer with one hand and rotating the vial directly with the other hand when measuring the inclination angle, so it is especially difficult to reach high places with your hand. There was a problem in that it was difficult to accurately align the position of the bubbles in places where measurements were difficult.

On this point, Utility Model No. 56-31684, Utility Model Application No. 59-
No. 144416 and Japanese Utility Model Application Publication No. 60-8814 disclose a modification to the rotor that has a horizontal indicating bubble tube built into the base, and a finger can be attached to the outer ring of the rotor while holding the base with one hand. A structure has been proposed in which the rotor is driven directly by placing the finger on the rotor, or the rotor is connected to a built-in adjustment knob or gear adjacent to the rotor, and the rotor is rotated by placing the finger on the adjustment knob or gear. Although the above-mentioned problems have been somewhat improved, since there is only one measurement reference plane for the base, it is still difficult to easily measure various angles of inclination with respect to the vertical and horizontal directions. I had left it behind.

(Problems to be solved by the invention) By solving the above-mentioned problems of conventional inclinometers, it can be used to measure the angle of depression, especially in places where it is difficult to measure, such as at high places, when inspecting civil engineering, architecture, or construction parts. The purpose of this invention is to propose an inclinometer that is advantageous in easily and accurately measuring inclination angles such as elevation angles.

(Means for solving the problem) This invention consists of a case body having two measurement reference planes extending orthogonally to each other and used for measuring inclination angles with respect to the vertical and horizontal, and a cover that closes the internal cavity of the case body. An angle display scale plate is arranged on at least one surface of the case body and the cover, and a ring having a pointer to check with the angle display scale plate and a level indicator bubble tube is rotatably built into the case body. A rotary knob that is held and exposed from the case body is conductively connected to the ring within the case, and the case body has a grip adjacent to the rotary knob. It is an inclinometer.

(Function) A ring with a horizontal indicating bubble tube provided inside the case body is connected to a rotary knob exposed from the case body, and can be rotated by operating the rotary knob with a finger. It's becoming like that. Furthermore, this ring is equipped with a pointer that is compared with the angle display scale plate located on the case body and/or on the cover surface that closes the internal cavity of this case body, so that the two measurement reference planes provided on the case body are Selectively place either one of them on the surface to be measured, and operate the rotary knob with the finger of the hand holding the grip so that the horizontal indicator bubble tube is horizontal (see Figure 4 a, b). At this time, by reading the angle of the angle display scale plate that matches the pointer,
Even in locations where measurement is relatively difficult, inclination angles (elevation angles, depression angles, etc.) relative to the vertical and horizontal can be easily, reliably, and stably measured.

(Example) The inclinometer according to this invention is shown in FIG. 1, and the cross section AA and longitudinal section BB are also shown.

In the figure, reference numeral 1 denotes a case body constituting an inclinometer, and this case body 1 has two measurement reference planes S and L that extend perpendicularly to each other and are used for measuring inclination angles with respect to the vertical and horizontal. 2 is a cover that closes the internal cavity of the case body 1, and 3 is an angle display scale plate. The angle display scale plate 3 is shown here as having a protective plate 3a and is arranged on the surface of the cover 2. However, this angle display scale plate 3 is
Anything can be applied, such as something that is stuck to the case body 1 or the cover 2, or something that is integrally formed and engraved thereon, and is not particularly limited. Further, 4 is a ring (hereinafter simply referred to as a center gear) consisting of a main ring 4a and a sub-ring 4b, which is rotatably held inside the case body 1, and this center gear 4 is checked against the angle display scale plate 3. It has a pointer 5 and a bubble tube 6 for horizontal indication. Reference numeral 7 denotes a rotary knob exposed from the case body 1, and this rotary knob 7 engages with teeth provided on the outer periphery of the center gear 4 via a pinion gear 8 and an idle gear 9 connected to the pinion gear 8. By rotating the rotary knob 7, the gear 4 can be rotationally driven. Reference numeral 10 denotes a grip provided adjacent to the rotary knob 7, and this grip is shown here as a two-piece structure formed by integrally forming the case body 1 and the cover 2 and combining them. Further, 11 is an arm for rotatably holding the idle gear 9 within the case body 1;
2 is a screw that connects the case body 1 and the cover 2, 13
is the name plate provided on the surface of cover 2,
14 is a thrust gasket for adjusting the thrust along the rotation axis of the center gear 4.

As for the materials of this inclinometer, the case body 1, cover 2 and grip 10 are made of ABC resin, the angle display scale plate 3 is made of aluminum, the protection plate 3a is made of polycarbonate, and the rotary knob 7 is made of ABC resin.
The horizontal indicating bubble tube 6 can be made of acrylic, the center gear 4 and pinion gear 8 can be made of ABC, and the idle gear 9 and arm 11 can be made of polyacetal.

FIG. 2 shows the inside of the case body 1 with the cover 2 removed, and the horizontal indicating bubble tube 6 is fixed between the rims of the center gear 4 using a holding frame.
It can be seen that the center gear 4 is transmission connected to the pinion gear 8 via the idle gear 9.

FIG. 3 shows a perspective view of the assembled structure of this inclinometer.

To measure the inclination angle of a structure or a construction part with respect to the vertical and horizontal using this inclinometer, two measurement reference planes S and L provided on the case body 1 are used (see FIG. 1).

Figure 4a shows that when measuring the inclination angle using the S measurement reference plane, the inclination angle is particularly measured when the horizontal length is 1 (unit length) with respect to the vertical length N of a structure such as a building. This is an example of a case. In addition, when measuring the slope angle using the L measurement reference plane, Fig. 4b shows the slope angle when the horizontal length is N for the vertical length 1 (unit length) of the construction part, especially in civil engineering. This is an example of a case where There are no particular restrictions on how to use the measurement reference surface, and the measurement reference surface can be selected depending on the situation at the time.You can apply the S or L measurement reference surface to the measurement surface and use the finger (thumb) of the hand that grips the grip 10. The rotary knob 7 may be rotated so that the horizontal bubble tube 6 becomes horizontal. When measuring the inclination angle, if a comparison table is provided on the surface of the case body 1, the slope length (normal length) can be easily determined from the measured inclination angle.
By displaying the slope corresponding to the angle on the angle display scale plate 3, the slope can be known at the same time.

In this embodiment, as shown in FIG. 5a, a horizontal indicating bubble tube 6 is arranged between the rims of the center gear 4,
Although this center gear 4 is transmission-connected using an idle gear 9 and a pinion gear 8, it can also be driven by, for example, a transmission connection between the center gear 4 and the pinion gear 8 via a belt as shown in FIG. 5b. You can also do it.

(Effect of the invention) According to this invention, structures such as civil engineering architecture, etc.
When measuring inclination angles and slopes, such as elevation and depression angles, especially in places that are difficult to reach, use the measurement reference surface (S surface or L surface) of the inclinometer and hold it with one hand to measure the inclination angle and slope relative to the vertical or horizontal plane. This inclinometer has great practical value as it allows quick and accurate measurements.
