Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ruler for guiding cutting of cutters, circular saws, etc.

[Conventional technology]

Conventionally, there was no dedicated guide ruler used when cutting workpieces such as wood and plastic materials, and 30°,
For angles of 45° and 60°, a triangular ruler is used and a cutter or circular saw is attached to the edge of this ruler for cutting, but for angles other than 30°, 45°, and 60°, The angle is determined in advance with a protractor and the guide ruler is applied to cut according to this angle, which is time consuming and less efficient, and the work is only moved by placing the guide ruler on top of the workpiece and holding it down by hand. In some cases, the work was difficult because one hand was occupied when holding the guide ruler.

[Problem that the invention attempts to solve]

The present invention solves such drawbacks, and it is technically possible to provide a cutting guide ruler that integrates a guide ruler and a protractor and allows accurate cutting by installing the guide ruler at a predetermined angle. This is a challenge.

[Means for solving problems]

A locking plate 4 that locks to the edge 3a of the workpiece 3 is provided on the lower edge of a protractor plate 2 with a protractor scale 1 arranged around it, and a scale alignment plate 5 that aligns the protractor plate 2 with the protractor scale 1 at the center of the protractor plate 2. A ruler mounting plate 6 is provided on one side of this scale setting plate 5 in a direction perpendicular to the scale setting plate 5, and a guide ruler plate 7 is freely slidable in a direction perpendicular to the scale setting plate 5 at the upper end of this ruler mounting plate 6. establish.

[Effect]

Place the protractor plate 2 on the workpiece 3, lock the locking plate 4 to the edge 3a of the workpiece 3 to fix the protractor plate 2 on the workpiece 3, and then rotate the guide ruler plate 7. When the reference mark 8 on the scale setting plate 5 is aligned with the predetermined minute scale 1, the guide ruler plate 7 is set at a predetermined angle.

In this state, by applying a cutter or a circular saw to the guide edge of the guide ruler plate 7 and moving it along the guide edge, the workpiece 3 can be cut at a predetermined angle.

〔Example〕

The minute scale 1 in the drawing has a degree scale in the upper half, a gradient scale in the lower half, and the degree scale is on the scale alignment plate 5.
The case is shown in which the upper end notch 9 is used for alignment, and the gradient scale is aligned at the lower end.

The scale setting plate 5 is shown fixed with bolts and nuts 11.

This guide ruler plate 7 is shown in the form of a channel, and when installing this guide ruler plate 7, a grip plate 13 is provided on the ruler mounting plate 6 and moves in and out by the rotation of a cam screw 12. The tip gripping piece 14 of the gripping plate 13 grips and holds one side edge 7a of the guide ruler plate 7, 15 is a holding plate, and 10 is a lever.

It is best to manufacture this product using stainless steel material.

[Effect of idea]

Since the present invention is configured as described above, the protractor plate 2 is placed on the workpiece 3, and the locking plate 4 is attached to the edge 3a of the workpiece 3.
After fixing the protractor plate 2 on the workpiece 3 by locking it, the guide ruler plate 7 is rotated to set the scale setting plate 5.
When the is set to the predetermined minute scale 1, the guide ruler plate 7
is set at a predetermined angle, and in this state, by sliding and moving a cutter or circular saw along the guide edge of the guide ruler plate 7, the workpiece 3 can be cut at a predetermined angle.

Therefore, since it is only necessary to align the scale setting plate 5 with the degree scale 1, it is possible to easily cut at angles other than 30°, 45°, and 60°. Since the guide ruler plate 7 is also fixed via the ruler mounting plate 6 and the scale setting plate 5, the protractor plate 2 and the guide ruler plate 7 do not move, which makes cutting easier.

Also, if the length of the guide ruler plate 7 is smaller than the width of the workpiece (3 widths) and the length of the guide ruler plate 7 is insufficient, it is convenient because the guide ruler plate 7 can be moved while being slid. Furthermore, the guide ruler plate 7 can be pulled out from the ruler mounting plate 6 and used as a straight line ruler, which has excellent practical effects.

Claims (1)

[Scope of utility model registration request] A locking plate that locks to the edge of the workpiece is provided on the lower edge of a protractor plate with a minute scale arranged around it, and a scale adjustment plate that is rotatable to match the minute scale is provided at the center of the protractor plate. A cutting guide ruler characterized in that a ruler mounting plate is provided on one side of the scale alignment plate in a direction perpendicular to the scale alignment plate, and a guide ruler plate is provided at the upper end of the ruler mounting plate so as to be slidable in the direction orthogonal to the scale alignment plate.
