Description

[Detailed Description of the Invention] The present invention relates to a guide ruler that is most suitable for cutting a large number of grooves at a predetermined angle in a board or the like using an electric tool during construction.

Recently, it has become possible to easily cut grooves in board materials during construction using power tools. When a large number of fitting grooves are formed at regular intervals and at a prescribed angle, it takes a lot of time to draw lines (mark) for the grooves, and conventionally, a piece of wood was used as a guide ruler for power tools. This work was done by cutting one groove, removing the needle, and nailing the piece of wood to the next groove line, which was extremely inefficient.

The present invention not only allows the angle of grooves and other cutting operations to be set arbitrarily, but also fixes the set angle, and moreover, can be easily and accurately fixed to the plate material to be cut, allowing accurate cutting operations using power tools. The purpose of the present invention is to provide a guide ruler for cutting work in architecture, which enables the following.

In the figure, 30 is an operating handle for the tightening rod 16, and 31 is an operating handle for the adjusting screw 26.

Incidentally, a scale may be formed by attaching appropriate graduations to the side surface of the guide ruler main body 1 or the ruler piece 2.

Next, an example of operation will be explained.

Figure 1 shows the grooves for the stair treads and the grooves E for the closing plates on board B.
An example is shown in which the base lines L□ and L2 are drawn near one end edge B2 and the other end edge B3 of the plate material B, respectively.

First, in the example of cutting the grooves E, the base points P of each groove E are displayed (marked) at predetermined intervals on the base line L2.

The guide ruler main body 1 is moved by sliding the reference point setting piece 29 in accordance with the distance between the guide portion C1 and the cutting edge C2 of the power tool C.
Set the distance from the side of the base point setting piece 29,
Set the angle of the guide ruler body 1.

In this case, any angle can be set by abutting the ruler piece 2 against one side wall surface B1 of the plate B.

When the angle is set, the tightening rod 16 is tightened by the operating handle 30.
to fix the ruler piece 2.

The guide ruler body 1 is moved so that the base point setting piece 29 matches the base point P, and at that position, the pivot shaft 14 is rotated by the handle 19, and one side edge of the plate material B is moved by the clamping plate 18 and the guide ruler body 1. The tip of the guide ruler main body 1 is fixed by holding the portion B2.

By tilting the handle 19, it can be locked even more firmly, but the handle 19 must be oriented parallel to the guide ruler main body 1.

Next, the movable mounting member 20 is slid in accordance with the width of the plate material B, and the rear end portion of the guide ruler main body 1 is firmly fixed by the second clamping means 5.

By removing the arm par 28 or tilting it to the opposite side, the guide portion C1 of the power tool C will not be obstructed in any way.

Further, since the force 41 C1 normally has a considerable height, the tilted handle 19.22 does not pose any problem.

Then, the guide portion C1 of the power tool C is connected to the guide ruler main body 1.
The groove E can be formed accurately by cutting the groove E in contact with the groove E.

Next, in order to cut the groove E, the fixation by the first clamping means 4 and the second clamping means 5 is released, and since the ruler piece 2 is fixed, it is moved at the same angle, and the base point setting piece 29
It is sufficient to perform the above-described operation to set the position where P matches the next base point P.

To cut a groove, the guide ruler main body 1 may be set at the opposite angle.

According to the guide ruler for cutting in architecture of this invention,
Not only can cutting operations be carried out accurately and easily using power tools, but the cutting angle can also be set arbitrarily, and by sequentially moving the set angle while keeping it fixed, cutting operations at the same angle can be performed. As shown in the figure, there is no trouble such as marking each cutting part or installing a guide piece of wood, and the work can be carried out quickly.

In addition, the guide ruler body is equipped with a stopper for power tools that can be slid and adjusted, so it is safe and there is no risk of over-cutting. It is easy to set the starting point.

Furthermore, since the clamping plates of the first and second clamping means for fixing both ends of the guide ruler body to the plate material are disc-shaped, no matter what angle the guide ruler body is at, the side edges of the plate material It has the effect of holding together.
