JP3246935U - Adjustable size ruler & round ruler with even graduations - Google Patents

Abstract

[Problem] Rather than using a ruler to measure length in the same way as a ruler, adding small circles every 2 mm and large circles every 10 mm to the solid lines of the even graduations allows for quicker determination. [Solution] A ruler 1 has broken lines 2 engraved on odd graduation lines every 2 mm, solid lines 3 engraved on even graduation lines every 2 mm, large circles 4 on even graduation lines every 10 mm, small circles 5 on odd graduation lines every 2 mm, and rectangular lines 6 on odd graduation lines every 10 mm. A ruler has broken lines 13 on odd graduation lines every 2 mm, small circles 9 on solid lines of even graduation lines every 2 mm, and large circles 10 on odd graduation lines every 10 mm, and italics 11 with large numbers on the even graduation lines and italics 12 with small numbers on the odd graduation lines.

Description

This invention relates to rulers and scales.

It took a lot of time to count the length of each line, every 1mm, using a ruler just like a set square, and to draw parallel lines to the dimensions taken on layouts, squares, and shapes.

We had to use a set square to draw parallel lines by sliding from top to bottom using several measurement marks, and we also had the problem that rulers usually only have markings every 1 mm.

Steps to resolve the issue

Rulers and rulers also have even-numbered scales that measure in 1mm increments, with one large circle every 10mm and one small circle every 2mm, allowing you to quickly distinguish between one, two, and three marks to mark the dimensions.

Effect of the idea

The ruler has even graduations, with large circles every 10 mm and small circles every 2 mm, making it easy to measure. The wide 2 mm intervals make it easy to see and are gentle on the eyes. The ruler also makes it easy to measure quickly, jumping from one to four graduations.

Use a ruler to draw lines on shapes and squares, and also draw lines on the cut pieces to match the dimensions of the reference lines, or slide them up and draw further up. Use a ruler to measure objects quickly and easily, jumping between the small and large circles on the scale.

For example, on a ruler, you can also draw large circles every 10 mm and small circles every 2 mm to match the measurements before and after the even graduations. When creating squares, you can draw five lines at equal intervals of 22 mm and 27 mm. If the odd graduations on a ruler are 33 mm, you would measure from 30 mm on the even graduations to the adjacent line. You can measure back and forth between the first graduation and four graduations on the small circle on the ruler, and then the large circles every 10 mm.

Claims (2)

This flexible dimension-matching ruler is characterized in that a single color of red scale lines are engraved on the transparent plate of the ruler body, short broken lines are added at odd scale lines aligned with each other every 2 mm in units of 1 mm, and solid parallel lines are added at even scale lines every 2 mm, two types of top and bottom lengths, 54 mm and 104 mm, are created, 0.25 mm is shaved off the upper side surface for accurate dimensions when drawing with a 0.5 mm thick core, and small circles are formed here and there at even scale lines every 2 mm and large circles are formed every 10 mm. 2. A round ruler with even graduations as claimed in claim 1, characterized in that the ruler has odd graduation lines with broken lines and even graduation lines with solid lines lined up every 1 mm, odd graduation lines with short thick rectangular lines and small numerical values at 5 mm and 15 mm onwards every 10 mm, even graduation lines with long thick rectangular lines and large numerical values at 10 mm and 20 mm onwards every 10 mm, and small circles at even graduations every 2 mm and large circles at 10 mm onwards.
