Description

  The present invention relates to a ruler.

  Conventionally, the drawing method using a ruler is the most basic drawing method in schools and workplaces. By using a protractor and a scale, a geometric figure or a figure with a more complicated pattern can be created.

Currently, drawing on a PC is the mainstream in many cases. However, many hand-drawn drawing methods are also used. For example, it is used when a student examines a composition during class. The most commonly used drawing with a ruler is to draw a corner with a fixed angle. Conventionally, when drawing an angle having a fixed angle, a scale and a semicircular protractor are simultaneously used, and the drafting process is as follows.
1. A first side that is a line segment of a predetermined length is drawn on the drawing.
2. Remove the ruler and use a semicircular protractor.
3. Align the straight side of the semicircular protractor with the first side.
4). The center of the semicircular protractor is aligned with one end of the first side.
5. Point the arc-shaped side of the semicircular protractor corresponding to the required angle.
6). The one end of the first side and the point are connected using a scale.
7). A line connecting the one end and the point is drawn.

  The above drafting process is quite cumbersome and requires the use of a scale and a semicircular protractor at the same time, which is inconvenient. In each of the above steps, it is necessary to align the scale or semicircular protractor with the center of a circle, a side line, or the like, and an angle or figure error occurs depending on the user's vision or operation.

  Therefore, the present inventor considered that the above-mentioned drawbacks could be improved, and as a result of intensive studies, he came up with a proposal for the present invention to improve the problem reasonably and effectively.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a ruler having a length measuring function and an angle measuring function.

  Further, the present invention provides a ruler that is convenient for carrying and can simplify operations such as drawing and angle measurement.

  In order to solve the above-described problems and achieve the object, a ruler according to the present invention includes a main body, an extending portion, a length measuring portion, and an angle measuring portion. The main body has a long side on one side. The extending portion extends outward from the long side of the main body, and a recess is formed at a location connected to the main body. The length measurement part is formed in the longitudinal direction on the side where the extension part of the main body is formed, and extends from the extension part to the end of the main body. The angle measuring unit has a concave portion as a center and is distributed radially in the main body.

  According to the present invention, when creating a geometric figure by conventional techniques, a large number of tools are prepared, and through a complicated process, a corner having a fixed angle can be drawn at a high speed. Since operations such as drawing creation and angle measurement can be completed, the efficiency of drafting can be improved. By combining the conventional scale and the protractor together, the portability can be improved, and advantages such as easier use can be obtained.

A ruler according to a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is an inclined view showing a ruler according to the first embodiment of the present invention. As shown in FIG. 1, the present invention has a main body 10 made of a transparent material, which is a long rectangular object made of a plastic material such as acrylic or PVC. 12, a length measurement unit 13 and an angle measurement unit 14 are provided, and each side of the main body 10 has a long side 101.

The extending portion 11 extends toward the outside of the long side 101 of the main body 10, and a concave portion 12 is formed at a location where the main body 10 and the extending portion 11 intersect perpendicularly. The length measuring unit 13 is provided on the surface of the main body 10 and is formed in the same longitudinal direction as the one side having the extending part 11 of the main body 10. It is extended from one side toward one end of the main body 10. The angle measuring unit 14 is provided on the surface of the main body 10, and scales in units of measure are distributed radially in the main body 10 with the recess 12 as a center.

  Incidentally, when the length measuring unit 13 and the angle measuring unit 14 are installed on the main body 10, they are installed on the surface of the main body 10 by a method such as printing, screen printing, or spray coating, other than being integrally molded with the main body 10. . In order to respond to different requirements at the time of use, an international unit system (meter, millimeter, degree) or a non-international unit system is adopted as a unit of scale of the length measuring unit 13 and the angle measuring unit 14.

  FIG. 2 is an operation schematic diagram showing the ruler according to the first embodiment of the present invention. As shown in FIG. 2, when drawing a narrow angle with a fixed angle according to the present invention, first, the first side 21 is extended so as to extend toward one end of the main body 10 starting from the concave portion 12 of the main body 10 according to the required length. The length to be drawn is the required length collated with the unit of measure of the length measuring unit 13.

  Next, after the concave portion 12 is a center and the main body 10 is rotated to a necessary angle, the scale unit of the angle measuring unit 14 is aligned with or overlapped with the first side 21 (displayed at 60 degrees in the drawing of the present embodiment). Thus, the second side 22 is drawn by extending toward the one end of the main body 10 starting from the concave portion 12, and the angle between the first side 21 and the second side 22 is a narrow angle of 60 degrees.

  When drawing a polygon, the drawing step for each line is similar to the implementation method shown in FIG. 2, and the drawing operation is performed after calculating the narrow angle of each side according to the required number of sides of the polygon. Complete, but omit restatement.
