Description

The present invention relates to an injured gauge capable of providing a contour mark for drilling a square hole having standardized dimensions such as an outlet installation hole and a power switch hole on a wall surface in electrical work, construction work, etc. is there.

Conventionally, as this kind of injured gauge, for example, there is one with a spirit level as shown in FIGS. 14 and 15. This injured gauge is said to be able to significantly improve work efficiency when drilling square holes with standardized dimensions such as outlet installation holes and power switch holes on the wall surface, and has the following configuration. (Patent Document 1).

This injured gauge has a rectangular parallelepiped shape made of transparent synthetic resin having a required thickness, a front surface 11a having a short dimension of 50 to 55 mm and a longitudinal dimension of 95 to 100 mm, and has a plate shape on another surface 11b of the gauge body 11. It is assumed that the magnet M is fixed. Then, it is assumed that the transparent bubble tube portions 12, 12 for measuring the horizontal and vertical positions are arranged in the inside of the gauge body 11 along the longitudinal direction and the minor dimension direction in the directions orthogonal to each other. Each bubble tube portion 12 is provided with a hole 12a having a slightly bulging central portion along the longitudinal direction and the short dimension direction inside the gauge body 11, and is used for confirming the horizontal state on both sides of the central portion of the hole 12a. An annular wire 13 to be a mark is formed, and a liquid L is filled in the ring road 13 while leaving bubbles B, and the ring road 13 is sealed with a stopper 14.

To make a contour mark for drilling a square hole with standardized dimensions such as an outlet installation hole or a power switch hole on the wall surface using an injured gauge having such a configuration, make the gauge body 11 horizontally long. In this case, the front surface 11a has a vertical dimension of 50 mm or 51 mm and a longitudinal dimension of 95 mm. By setting such numerical dimensions, it is possible to appropriately attach a contour mark for forming an outlet installation hole by using the outer peripheral edge thereof.

In order to attach the contour mark for forming the outlet installation hole to the wall surface, as shown in FIG. 16, the gauge body 11 is brought into contact with a predetermined position of the surface material 15 of the wall so as to be vertical in the longitudinal direction, and is horizontal. If the bubble B of the bubble tube portion 12 is adjusted so as to be located between the annular lines 13 and 13, it can be confirmed that the bubble tube portion 12 is horizontal, and the 51 mm side of the gauge body 11 can be confirmed. Is horizontal and the 95 mm side is vertical. Therefore, if the outer line of the gauge body 11 at this time is copied onto the wall surface, the position where the rectangular hole having a length of 95 mm and a width of 51 mm is formed is accurately marked.

By the way, in recent years, not to mention offices and factories, double-sized outlets have become widely used in ordinary households, and along with this, it has become necessary to support double-sized outlets.

However, the above-mentioned conventional injured gauge can only handle a series of sizes, and in the case of a double-sized outlet installation hole, the gauge body 11 is parallel while the gauge body 11 is in contact with the wall surface. We had to move it and continuously copy the outline of the gauge body 11, but in such a case, it is necessary to accurately attach the contour mark for forming the outlet installation hole of the size of two consecutive outlets. Had the problem of not being able to.

Further, in order to attach the contour mark for forming the outlet installation hole to the wall surface by using the conventional injured gauge, as shown in FIG. 16, a suitable portion of the front surface 11a of the gauge body 11 may be pressed with a finger. Alternatively, the gauge body 11 is positioned on the wall surface by holding the circumference of the gauge body 11 with a finger.

However, since the gauge body 11 is made of a transparent synthetic resin and its front surface 11a is smooth, simply pressing an appropriate portion of the front surface 11a with a finger makes the pressed finger slippery, and the finger is slippery. The gauge body 11 also slips and moves in response to the slippage of the gauge body 11, and there is a problem that the gauge body 11 cannot be accurately positioned on the wall surface.

Further, when the circumference of the gauge body 11 is held by a finger, when the contour mark is attached, the holding finger becomes an obstacle and must be changed, and at that time, the position of the gauge body 11 is changed. It had the problem that it could shift.

Therefore, the present invention aims to solve the problem of the conventional injured gauge, and is a contour for drilling a square hole having standardized dimensions such as an outlet installation hole and a power switch hole on the wall surface. When marking, the outlet and power switch can be of either a series size or a double size, and the gauge body can be easily pressed, and the pressed finger slips. By making it difficult, the gauge body also slips and is difficult to move, and it is not necessary to change the gauge body, prevent misalignment at that time, and provide an injured gauge that can accurately position the gauge body on the wall surface. It was made for the purpose of doing so.

Therefore, in the injured gauge of the present invention, two rectangular parallelepiped gauge bodies 1 and 2 made of transparent synthetic resin are superposed, and these superposed gauge bodies 1 and 2 are flattened via a hinge 3. It is assumed that they are connected so that they can be opened.

In the injured gauge of the present invention, the one gauge body 1 has a dimension of 41 to 51 mm in the short dimension direction and a dimension in the longitudinal direction of 89 to 99 mm, and the other gauge body 2 has a dimension in the short dimension direction. Is 46 to 56 mm, and the dimension in the longitudinal direction is 90 to 100 mm.

In the injured gauge of the present invention, the hinge 3 has one bracket 3a fixed to the rear surface 1b of the one gauge body 1 and the other bracket 3b fixed to the front surface 2a of the other gauge body 2. ..

In the injured gauge of the present invention, finger insertion portions 4 and 5 are provided at opposite positions of the one gauge body 1 and the other gauge body 2, respectively, and inside at least one of the gauge bodies 1 and 2. , It is assumed that the bubble moving portion 6 is provided along the short dimension direction or the longitudinal direction.

In the injured gauge of the present invention, the finger insertion portions 4 and 5 are through holes so as to penetrate from the front surfaces 1a and 2a of the gauge bodies 1 and 2 to the rear surfaces 1b and 2b, and the gauge bodies 1 and 2 respectively. It is assumed that it is installed in at least one place.

The injured gauge of the present invention is configured as described above, and is used to provide a contour mark for drilling a square hole having standardized dimensions such as an outlet installation hole or a power switch hole on a wall surface. When the square hole has a series size, the two gauge bodies 1 and 2 are overlapped (closed), and when the square hole has a double size, the two gauge bodies 1 and 2. If 2 is opened, contour marks corresponding to each can be added.

Further, in the injured gauge of the present invention, even when the gauge bodies 1 and 2 are overlapped (closed) or opened, fingers are inserted into the finger insertion portions 4 and 5 provided on the gauge bodies 1 and 2. By hooking and pressing the gauge bodies 1 and 2 against the wall surface, the gauge bodies 1 and 2 can be easily pressed and the pressed fingers become less slippery, so that the gauge bodies 1 and 2 also move without slipping. It becomes difficult, and the gauge bodies 1 and 2 can be accurately positioned on the wall surface.

Further, in the injured gauge of the present invention, when the contour mark is attached, a finger is hooked on any of the finger insertion portions 4 and 5 provided on the gauge bodies 1 and 2, and the gauge bodies 1 and 2 are pressed against the wall surface. If it is attached, the pressed fingers do not get in the way, so it is not necessary to change the gauge bodies 1 and 2, and it is possible to prevent misalignment at that time, and the gauge bodies 1 and 2 are accurately positioned on the wall surface. be able to.
