Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides an inner portion and an outer portion on a ruler and presses the inner portion so that the inner use contact surface comes into close contact with the side surface of a rectangular plate or bar to be inspected, drawn or measured. It relates to a ruler with a step that improves the accuracy of inspection, drawing and measurement.

[0002]

2. Description of the Related Art Conventionally, in the case of an angle straight scale, a so-called curved ruler, a right angle ruler, a so-called square, a fixed ruler, a fixed ruler, a triangle ruler, and a straight ruler, inspection and drawing of dimensions and angles are mainly performed.
As a measuring instrument, it has been used in the construction industry, manufacturing industry, ordinary households, and the like. And the four-sided ruler did not appear in the market.

[0003]

The conventional rulers have the following drawbacks. In the case of a straight angle, when a rectangular plate or bar is thick, a vertical line is drawn by pressing against the side surface of a short branch or a long branch so as to hook the inside thereof, so that a vertical line can be drawn accurately. However, in the case of thin rectangular bars or rods, the contact area that gets stuck on the inner working surface of the short branch or the inner working surface of the long branch is reduced, so the pressing is insufficient, and the displacement and wobble occurs, and the accurate vertical I can't draw a line. The flat square ruler has the same principle.

Further, in the case of the square ruler with a base, a thick short piece is caught on the side surface of a plate or a rod, regardless of whether the plate or the bar is thick or thin, so that a vertical line can be drawn accurately. However, when used on a flat surface, the short piece is thick, so that the long side floats off the flat surface. In the case of the conventional ruler and ruler, it is mainly equipped with a stand.
The table is pressed against the side of a square plate or bar, but the ruler body with the width of the table floats on a flat plate or flat surface, so that accurate dimension and angle inspection, drawing and measurement cannot be performed. or,
Conventional triangular rulers and straight rulers are often used on desks and flat surfaces, and are often positioned visually, so it is difficult to position a three-dimensional object, and the present invention solves the above problems. is there.
