[0002]

[Prior art]

 Traditionally, drawing tools such as triangle rulers, protractors, compasses, straight scales and design rulers have been used for drawing and arts and crafts in math classes, but they had the following drawbacks. . 1. It was inconvenient to carry because I needed a lot of equipment. 2. It requires a lot of equipment and occupies a large area on the table when it is used. 3. When the equipment was put apart, it took time to find the equipment needed. 4. When drawing a corner, it was necessary to use a protractor and then draw a connecting line with a ruler, which was a complicated procedure. 5. When I draw a regular polygon with a ruler, the process is complicated and time consuming. 6. When drawing a circle with a compass, if the applied force was not uniform, the density of the lines was not uniform. Due to the above-mentioned drawbacks, there has been a demand for a multi-function ruler which has functions of a triangle ruler, a protractor, a compass, a straight scale, and a pattern ruler and is convenient to use.

 FIG. 1 is a perspective view of the present invention after assembly, and FIG. 2 is an exploded perspective view of the present invention. According to the present invention, a single straight main body 1 is provided with a plurality of protrusions 13 at appropriate positions, a disc portion 23 is provided at one end, and an angle scale 25 and a number of sides are provided at appropriate positions on the disc portion 23. One turning ruler 2 provided with a scale 24, a flat compass 3 having a plurality of small circular holes 31 arranged on the upper side thereof, a scale fixing knob 4 provided with an angle table 41 thereon, and one rotation center point 51. The above-mentioned structure is connected to the vertical scale main body 1 by the scale fixing knob 4 and the fixing knob 5.

FIG. 3 is a diagram showing the operation of the swivel ruler of the present invention, and FIG. 4 is a diagram showing the operation of the flat compass of the present invention. The feature is that the swivel ruler 2 connected to the straight-scale main body 1 swivels with the scale fixed knob 4 or the fixed knob 5 as the center of the circle, and the angular scale 25 and the scale fixed knob 4 on the swivel ruler 2 By combining the angle table 41, various angles can be drawn, and the lengths of the two sides of the angle can be determined based on the scale on the ruler. Further, a regular polygon can be drawn by a combination of the side number scale 24 on the turning ruler 2 and the side number table 42 on the scale fixing knob 4. In addition, the present proposal, on the other hand, allows the flat compass 3 to be rotated around the rotation center point 51 on the fixed knob 5 in the small circular hole 31 on the flat compass 3 to form circles or arcs of various radii. It can be drawn and thus has the function of replacing various conventional drafting tools.

In order to smoothly turn the flat compass 3, three convex points are provided at appropriate positions on the straight-scale main body 1, and the height of the three points is equal to the height of the turning center point on the fixed knob. Since the straight-sized main body 1 is set slightly higher, the flat compass 3 is smoothly rotated, and a plurality of circular holes with a predetermined radius are formed on the joint surface between the straight-sized main body 1 and the flat compass 3. 11 is provided and a circle can be drawn.

A plurality of design holes 32 for drawing various designs are provided on the flat compass 3 of the present invention, and are used for drawing simple basic geometric figures.

The combination of the swivel projection and swivel track of the swivel ruler 2 of the present invention is displayed in the A and B parts of FIG. In the swivel ruler 2 and the straight length main body 1 of the present invention, the swivel protrusion 21 on the swivel ruler 2 and the swirl track 12 on the straight length main body 1 are closely combined. In the process of drawing a line, the required angle swivel ruler 2 is swiveled without changing the fixed position of the scale, and when plotting with changing the angle, slightly pull up the end 22 of swivel ruler 2 in the direction of A, The turning protrusion 21 on the ruler 2 is slightly disengaged from the turning track 12 on the straight-length main body 1, the contact between the two is loosened to adjust the turning ruler 2, and when the proper position is reached, the end of the turning ruler 2 ends. 22 should be returned to the original position.

[0016]

[Effect of device]
