Sheet steel simple scale compass

Abstract

To provide a revolutionary sheet steel compass which is yet another addition to the world-renowned stationery that Japan can be proud of, which fits easily into a pencil case, does not require a case, and is compact enough to fit inside a pencil case or wrap around the user's wrist for easy portability, and by connecting the compasses together, the user can draw large, perfect circles, and simply glue them together and trace the inside of the compass with a pencil to draw perfect circles, the compass having been achieved after countless attempts to improve upon the inconveniences, poor usability, and dangers of the needles attached to traditional educational compasses, then making a ruler that allows anyone, even elementary school students, to draw perfect circles safely and easily, without the need for a traditional compass.

Description

[Technical Field]

[0001] Of course, you can use a ruler to draw lines, but it is also the first in the world to be able to draw circles with a ruler, adding another item to the Japanese stationery that Japan is proud of around the world. [Background technology]

[0002] With this single ruler, anyone, even elementary school students, can easily draw a round circle. One stationery item that shows no signs of improvement is the forked compass, used by children from elementary school to adulthood for the sole purpose of drawing a round circle. Apart from compasses for precision drawings and nautical charts, it is difficult for anyone to use when drawing a round circle. This problem has been solved by using a single ruler instead of the conventional compass. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0003] It is a ruler made of thin steel, with a width of 1cm or 1.5cm, and lengths of 0 to 15cm and 20cm, marked with 0mm and 1cm. The steel plate can be bent into a curve, so you can draw circles by tracing the inside with a pencil or ballpoint pen. [Means for solving the problem]

[0004] Made from thin steel plate, this is the ultimate scale compass that can be easily carried anywhere, in a pencil case, file folder, or breast pocket. [Effects of the Invention]

[0005] Everyone, especially the younger students, were delighted with this product. Conventional compasses are difficult to write with and tend to slip on the writing pad, making it difficult to write with. However, with this plate steel scale compass, students can simply attach a circle of the desired size to the magnetic (magnet) and trace the inside of it with a pencil to draw a beautiful circle, which has been well received. BEST MODE FOR CARRYING OUT THE INVENTION

[0006] Conventional compasses have not shown any signs of improvement for decades or even centuries to come, but we are not criticizing compasses for drafting or nautical charts. Rather, they were developed for educational and arts purposes, with the sole aim of being able to draw circles quickly, neatly, and easily, using just a ruler. [Example]

[0007] Now that we know that a single line drawing ruler can replace a compass, we want to make it a better product that is safe and reliable so that even younger students can use it to study circles and pie charts quickly. [Industrial Applicability]

[0008] This plate steel scale compass can be used in a wide range of industries, including the education industry and stationery-related industries, and will be a replacement for conventional compasses in the future. [Brief explanation of the drawings]
