Description

The present invention relates to a ruler, a triangle ruler, and a protractor.

Today, a ruler, a triangle ruler, and a protractor are provided together as a ruler set due to their common usage.

However, the ruler, the triangle ruler, and the protractor are all easily lost due to their thin shape, and some points in the set are often lost, so it is difficult to manage them as a set.

Therefore, until now, it has been easy to manage the ruler set collectively by storing the ruler, the triangle ruler, and the protractor in a dedicated storage bag that can store the ruler set.

As mentioned above, it is desirable that rulers, triangle rulers, and protractors can be managed together as a ruler set due to their common usage. However, rulers, triangle rulers, and protractors are all easily lost due to their thin shape. Since some of the sets are often lost, there is a drawback that it is difficult to manage them as a set.

Therefore, the present invention comprises a ruler, a triangle ruler, and a protractor with protrusions and receiving holes, and each ruler, triangle ruler, and protractor protrusions are inserted and fitted into the other ruler, triangle ruler, and protractor receiving holes. By combining ruler, triangle ruler, and protractor, we provide ruler set, triangle ruler, and protractor that are easy to manage as a ruler set.

The ruler, the triangle ruler, and the protractor according to the present invention include a plurality of receiving holes 58 that are provided on the upper surface 52 of the base portion 52 and have a plurality of receiving holes 58 that are open downward. Triangular ruler, protractor protrusion 57 can be inserted and fitted with a ruler, triangular ruler, and protractor.

The height of each projection 57 in the ruler, the triangle ruler, and the protractor is set to a value smaller than the height of the ruler, the triangle ruler, and the base 51 of the protractor, and the value of the diameter is an adjacent projection. The value is smaller than the distance between the centers of the part 57.

This ruler, triangle ruler, and protractor are a combination of a ruler, a triangle ruler, and a protractor with different numbers of protrusions 57 provided on the upper surface 52 of the base 51.
