Description

  The present invention provides a novel ruler, compass, protractor, etc. for measuring line length, radius and diameter of circles and arcs, angles, etc., and drawing geometric figures such as lines, circles, arcs and corners. Related to geometric tools.

The conventional geometric tools currently used worldwide include the following tools.
(1) Ruler for measuring line length and drawing lines (2) Compass for drawing arcs (3) Protractor for measuring angles and drawing angles All of these tools They are both handled by conventional methods and perform geometric figure measurement and drawing work. That is, at present, drawing of a geometric figure is realized by performing a two-step laborious process of measurement and drawing using the above-described tools. In particular, when drawing an arc, two types of tools, a ruler and a compass, must be used separately. In contrast, the basic model (basic model SA, A1, B, B1, B2, B3 and C) of the geometric tool according to the present invention, which replaces a ruler, a compass, and a protractor, has a simplified coordinate hole mechanism. Since it is adopted, marking and drawing can be performed in one operation. The coordinate hole error prevention mechanism is a completely new mechanism used when creating a new tool as described above, and there is no example actually used in the whole world. Therefore, there is no prior art that completely corresponds to the present invention. However, since the present invention replaces any conventional geometric tools such as rulers, compass, protractors, etc. currently in use, these tools may be considered as prior art of the present invention.

  In the fields of education and industry, millions of people around the world can measure line length, radius and diameter of circles and arcs and angles, and geometry of lines, circles, arcs and corners. Geometric tools such as rulers, compass, and protractor are used to draw figures. And the user of these tools has experienced the trouble and trouble accompanying the inefficiency of these tools when using these conventional tools. In particular, preschool children and school children feel more stressed and annoyed by the use of the above tools, but they do not talk about such issues. The reason is probably that the existing ruler, compass, and protractor were established as the final shape, and the user assumed that there was no room for further invention. For this reason, a tool having a completely new shape relative to these conventional tools has never been invented. We, the three inventors, noticed the above problem and tried to solve the problem. We thought that a completely new mechanism should be invented and that the above problem could be solved if such a mechanism was employed in a geometric tool. Based on this idea, we spent the past few years to create a new geometric tool, and finally invented the new coordinate hole simplification mechanism shown below. And by adopting this new coordinate hole simplification mechanism, we have invented a basic model of a geometric tool that groups rulers, compass and protractor as shown below.

Coordinate hole simplification mechanism newly invented to create new geometric tools such as rulers, compass, protractors, etc. According to the present invention, lines, circles, arcs, angles after measuring with a ruler or protractor Instead of drawing geometrical figures such as the above, it is possible to draw directly with small coordinate holes. These coordinate holes have an appropriate size and shape, and are provided at appropriate positions on the tool body. The coordinate holes are provided at exact distances and angles and function as a complete simplification mechanism. The tool may be provided with another simplification mechanism.

This allows partial measurement with maximum accuracy and very simple, quick and accurate drawing of lines, circles, arcs and corners.

Using the coordinate hole simplification mechanism of the present invention for three groups of basic models (models A, B, and C) of new geometric tools applying the coordinate hole simplification mechanism according to the present invention, we Invented several new geometric tools to replace rulers, compass and protractors. And we select the basic model A, B, C group, which is a new geometric tool to replace the ruler, compass and protractor from the basic model of the newly invented geometric tool. A patent application was filed with the simplified mechanism. All these tools are used to measure line length, radius and diameter of circles and arcs, angles, etc., and to draw geometric figures such as lines, circles, arcs and corners in a very simple task. Invented. In particular, when drawing a circular arc, if a newly invented compass is used, there is no need to use two tools, a ruler and a compass, separately to perform different tasks. Unlike the conventional method of performing one task of measurement using a ruler and drawing a circle or arc as another task using a compass, according to the tool of the present invention, it is necessary to perform these separate tasks. There is no. The measuring part is an important part of the tool of the present invention, and if this single new tool is used, measurement and drawing can be performed simultaneously and very easily.
(1) Basic model-A, A1 : Ruler with coordinate hole (2) Basic model-B, B1, B2, and B3 : Compass with center leg assembly (with or without tilt slide, coordinate hole and simplified mechanism)
(3) Basic model-C : Protractor with coordinate holes and simplification mechanism

All of the general form tool parts of the basic model of the geometric tool according to the present invention are made of aluminum, metal, plastic or any material. The measuring part of all tools (removable and replaceable ruler part) can also be composed of a thin spring seat.

  The circular hole of the drawing tool can be provided with a metal or non-metal sleeve or ring. Thereby, if necessary, marking and drawing tools such as pens, pencils, ballpoint pens, microchips, metal pins, sketch pens, or any other marking tools and drawing tools can be used easily and without failure. . In addition, by providing the ring as described above, it is possible to prevent wear (wear and tear) of the coordinate hole and ensure the durability of the coordinate hole. By providing a female or male thread (screw) in a ring of circular coordinate holes, the ring can be secured to any particular marking, drawing and cutting tool having a corresponding female or male thread.

  The coordinate holes provided in the tool may be rectangular, triangular, or any suitable shape. The size depends on the desired tool, eg, a plotter (marker) such as a pen, pencil, ballpoint pen, microchip, metal pin, sketch pen, or any other marking tool, drawing tool and cutting tool.

  The removable and replaceable ruler in the novel tool according to the invention is formed to be able to accommodate measurement of line lengths up to 15 cm and drawing lines up to 15 cm. This ruler can be designed to any length as required. For example, it may be 30 cm, 40 cm, 60 cm, or the like. In order to draw very small circles and arcs very simply and easily, the length of the ruler may be shortened as necessary, such as 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, and the like. This allows us to use very small arcs or very large depending on the required radius by replacing the short or long ruler as required using only the center leg assembly and its corresponding parts. An arc can be easily drawn.

  The width of the ruler portion of the tool according to the present invention can be made narrower than the width of a conventional ruler currently used. Specifically, the ruler body is formed of a strip of spring plate or any very narrow plastic or metal or material.

  The tool of the present invention may be manufactured according to the FPS unit system (measurement scale by inch).

  The basic model of the protractor (Model-E) can be made up to 360 degrees, 180 degrees, or any angle measurement and any angle drawing.

(1) Basic model-A: Ruler with coordinate holes and simplification mechanism (see top of Fig. 1)
The ruler basic model-A of the present invention is manufactured so as to be usable up to 15 cm by adopting the coordinate hole simplification mechanism according to the present invention described above. With this tool, the coordinate hole is completely configured as a mistake prevention measure. This makes it very easy and very quick to mark 150 different lengths (1 mm to 150 mm) and draw lines of such length. In this ruler, 60 small coordinate holes are arranged in 4 rows at 1 cm intervals. Thereby, marking can be performed in units of 1 cm. When the ruler is made of a thick material, the coordinate holes may be conical (tapered holes). On the other hand, when the ruler is composed of a very thin spring seat, a cylindrical hole with a ring can be provided. This makes it possible to use marking tools and drawing tools such as pens, pencils, ballpoint pens, microchips, metal pins, sketch pens, or any other marking tools and drawing tools easily and without failure, as required. it can. Further, by providing ten small coordinate holes (conical shapes) at one end of the ruler body in millimeter units, marking in millimeter units can be performed. By combining markings in centimeters and millimeters, it is possible to accurately draw a line having a required length. This work can be performed quickly and easily and without any trouble compared to the work required by the method using a conventional ruler. If a separate metal leg pointer is used, the ruler can also be used as a compass for drawing a circle or arc. For this purpose, another 10 pointer holes (columnar holes for installing metal leg pointers as shaft legs of the compass) are provided at the other end of the same ruler body. Therefore, in this model, a total of 80 coordinate holes are arranged in four rows.

Basic model-A1: Compass with center leg assembly, coordinate holes and simplification mechanism (see Fig. 1 bottom)
By adopting the coordinate hole simplification mechanism according to the present invention, the ruler (basic model-A) is changed as described below and used as a compass for MODEL-A1 that can be used up to 15 cm. Can do. In this compass, a circle and an arc corresponding to a required radius can be drawn very easily and with as much accuracy as possible by a completely simplified mechanism. This compass is provided with 145 small coordinate holes. With this compass, measurement and drawing can be performed in units of 1 mm in a range of 6 mm to 150 mm. And a leg assembly is fixed to the center of 145 coordinate holes provided with a complete simplification mechanism. At the center of the leg assembly having a spiral spring, a metal leg pointer (needle) is provided as a compass foot. The pointer is inserted into a spiral spring that moves the pointer in the vertical direction along the Z axis (up and down). The 145 small coordinate holes with rings function as the legs of the compass when drawing. That is, a complete simplification mechanism is applied to this coordinate hole, and marking tools and drawing tools such as pens, pencils, ballpoint pens, microchips, metal pins, sketch pens, or any other marking tools and drawing tools are inserted. The Thereby, a circle and an arc can be drawn. A coordinate hole simplification mechanism is provided for measuring and drawing a circle having a radius of 5 mm to 150 mm. Instead of a leg assembly having a helical spring, the assembly may be modified appropriately to provide a leg assembly having a flat spring or any other shape spring. The leg assembly may not have a spring.

(2) Basic model-B: Compass with center leg assembly (with or without tilting slide, coordinate hole and simplification mechanism) (See Fig. 2)
We have invented a new compass (MODEL-B) that can be used up to 15 cm by adopting the coordinate hole simplification mechanism of the present invention described above. The compass mainly includes (1) a slide accommodating portion, (2) an inclined slide, (3) a leg assembly, and (4) a replaceable ruler. The ruler body has 15 coordinate holes with rings (functioning as compass legs when drawing) at 1 cm intervals as a complete simplification mechanism. Pencils, ballpoint pens, microchips, metal Marking and drawing tools such as pins, sketch pens, or any other marking and drawing tools are inserted. Thereby, a circle and an arc can be drawn. Optionally, coordinate holes of different sizes may be arranged in two or three rows on the same ruler body. Thereby, it is possible to use plotters (drawing tools) having the same ruler and different sizes.

  The ruler body, the inclined slide and the leg assembly are assembled together with the slide housing. A center leg assembly (a metal needle as a metal pointer having a helical spring that functions as a shaft foot of a compass) is fixed to a sleeve of the leg assembly in the same manner as the basic model A1. A spiral spring provided in the leg assembly can move the metal leg pointer in the vertical direction along the Z axis (up and down). Leg assembly, because the entire tilt slide is tilted and moved (up and down and left and right) at a fixed ratio (desirably any ratio between 3: 1 and 4: 1) along the X and Y axes. The whole can move left and right along the X axis with a value less than the required centimeter within a maximum moving distance of 9 mm. Then, after the leg assembly is tilted, the leg assembly is securely fixed by a locking mechanism provided in the assembly. By this sliding mechanism, the central part of the metal leg pointer fixed to the central part of the leg assembly can also be moved within a maximum moving distance of 9 mm with a value less than the required centimeter unit. As the ratio of Y: X increases, the moving distance of the inclined slide also increases. This improves accuracy and makes handling very easy. The recommended Y: X ratio is 3: 1. This means that every time the tilt slide moves 3 mm vertically, the metal leg pointer moves 1 mm horizontally. Therefore, the total moving distance of the inclined slide is 27 mm (9 × 3).

  The main function of the tilting slide mechanism is to reliably move the center point to the required position accurately, smoothly and quickly. That is, the tilt slide mechanism moves the entire leg assembly to move the metal center leg pointer to the required sub-centimeter value position very accurately, easily and quickly. Other mechanisms can be introduced to accomplish the same purpose. For example, a gear assembly mechanism, a lever assembly mechanism, a screw assembly mechanism, or any other mechanism can be used. The basic model-B of the compass with a spiral spring can be changed by omitting the inclined slide. Further, the basic model-B can be configured as a basic model-B1, a basic model-B2, and a basic model-B3 as shown in detail below.

Basic model -B1 : (See the top of Fig. 3)
In this model, the entire leg assembly is moved horizontally (left and right) within the maximum travel distance of 9 mm and less than the required centimeter by moving the axle assembly directly in the horizontal direction (left and right) along the X axis. Can be made.

Basic model -B2 : (Refer to the bottom of FIG. 3)
In this model, a small fork-shaped horizontal slide is provided at the left end of the ruler, and the horizontal slide is moved in the horizontal direction (left and right) along the X axis within a range of a maximum moving distance of 9 mm. Since a horizontal slide is attached to the ruler body, the ruler body can be moved horizontally. Thereby, after moving to the value below the required centimeter within the range of the maximum moving distance of 9 mm, it can be firmly fixed. Thus, in this model, the center leg assembly is always fixed at a constant center point without any movement of the entire center leg assembly. The entire ruler body can be moved within a maximum moving distance of 9 mm with a value less than the required centimeter unit.

Basic model-B3 : (Refer to the top of FIG. 4)
In this model, a ruler body is provided with a small coordinate hole with a ring (optionally two or three differently sized coordinate holes can be provided) and a leg assembly. By moving and adjusting the ruler body of the tool to the required position in the horizontal direction (left and right), the tool is moved by a value less than the required centimeter. After the position adjustment, the ruler body is firmly fixed. In this model, the ruler slides horizontally under the leg assembly along the direction of the entire lateral length. Thus, even in this model, the entire center leg assembly does not move at all, and the center leg assembly is always placed at a constant center point. Only the ruler can move up to 150 cm. All removable rulers belonging to the Model B group can be made of spring seats, transparent plastic, aluminum, metal, or any other material. The other parts of the tool can be formed of plastic, aluminum, metal, or any other material.

  In the basic model B3, instead of configuring the ruler body with a thin spring seat, the ruler body may be configured with a small rod having a single coordinate hole with a ring (a small rod in any cross section). Depending on the cross-sectional shape of the selected ruler, simple changes can be made to the other parts of the corresponding tool.

(5) Basic model-C: Protractor with coordinate holes and simplification mechanism (see bottom of Fig. 4)
We have invented a protractor (MODEL-C) that can be used up to 360 degrees by using the coordinate hole simplification mechanism of the present invention described above. This protractor is provided with a marking hole (coordinate hole) with a completely simple function, which makes it possible to measure angles up to 360 degrees with maximum accuracy and very easily, quickly and efficiently. Such corners can be drawn. This 360-degree protractor is provided with 36 main coordinate holes at intervals of 10 degrees. On the left side, nine sub-coordinate holes are provided at intervals of 1 degree in the clockwise direction. Nine sub-coordinate holes are provided on the right side at intervals of 1 degree in the counterclockwise direction. One coordinate hole (arbitrary hole) is provided at the center. That is, in this model capable of measuring from 0 degree to 360 degrees, a total of 54 or 55 coordinate holes with or without rings are provided in the clockwise and counterclockwise directions. Angle measurements can be made at 10 degree intervals and 1 degree intervals. If the left and right sub-coordinate holes are appropriately increased, it is possible to measure and mark values less than one degree. The sub-coordinate holes (7 + 7) are arranged in a trajectory outside the main coordinate hole so that the drawing operation can be performed with maximum accuracy. On the other hand, when a protractor having a large diameter is constructed, all the sub-coordinate holes (9 + 9) can be arranged in the trajectory inside the main coordinate hole. In this case, the protractor can be configured as a complete circle by eliminating the left and right extensions of the sub-coordinate holes.

  Alternatively, the protractor may be provided with 37 or 38 coordinate holes with or without a ring so that angle measurement up to 180 degrees can be performed.

  The protractor body can be formed of a transparent thin plastic, aluminum, other metal, or any other material. When the protractor body is made of a transparent plastic, as described above, the coordinate hole is provided with a metal ring.

Inventions of other geometric tools Geometry created to measure the length of lines, radius and diameter of circles and arcs, and angles, and to draw geometric figures such as lines, circles, arcs and corners Based on the working mechanism of the above three types of basic models of scientific tools, new geometric tools can be created. For example, with respect to the basic model-A1, 30 coordinate holes with rings can be arranged in a small strip of a ruler made of any material at intervals of 0.5 cm so that a maximum of 15 cm can be used. Similarly, for the ruler body of the basic model-B, coordinate holes can be provided at intervals of 0.5 cm. By making such a change, the total length of the inclined slide can be shortened by 15 mm. Further, the vertical movement distance of the inclined slide is limited to 12 mm (4 × 3), and the horizontal movement distance of the leg assembly is limited to 5 mm. By combining Model-A and Model-B, it is also possible to create an integrated new tool in which a limited number of coordinate holes are provided in a common ruler body.

Advantages of the tool of the present invention (1) A circle or arc drawn using all the tools of the present invention (model A and model B group) naturally has a clear center point. This is because drawing is performed using a new mechanism provided in the tool. The existence of the center point is mentioned because there are almost no tools that can draw circles with a small diameter without using a compass in existing tools (tools that can draw four or five different diameter circles). But the maximum diameter is slightly smaller than the width of the ruler). In the method of drawing with an existing tool, there is a circular cutout in the body of the tool, and the circle is drawn directly along this cutout. But these circles naturally have no center point. Therefore, when it is desired to mark the center point, a troublesome work of finding the center point is required. However, the problem of finding the center point does not occur in the tool of the present invention. This is because this new tool is created by adopting a completely new mechanism called coordinate holes, and circles and arcs are drawn by this new mechanism.
(2) Any marking tool and drawing tool such as a pen, pencil, ballpoint pen, microchip, metal pin, sketch pen, or any other marking and drawing tool can be used.
(3) With only one setting, it is possible to draw as many concentric circles with different diameters as possible.
(4) If a special cutting tool is used as a leg of a compass, paper, sheets, wrapping paper, and other arbitrary thin materials can be cut into a circle.
(5) Tools can be made in large sizes suitable for industrial use.
(6) Maintenance and repair of tools are very easy.
(7) Tool life is long.
(8) Reliability and accuracy are increasing.
(9) There is no need to use an accessory when drawing a circle or arc having a large radius.
(10) There is no need to handle two tools when drawing an arc.
(11) Efficiency is improved in accuracy and speed.
(12) The tool of the present invention is less expensive than the price of an existing tool in which many accessories are stored in a box.

  The geometric tool adopting the coordinate hole simplification mechanism according to the present invention and the working mechanism of the models A, B, and C groups according to the present invention can be applied to all existing geometric tools currently used in the world (for example, , Rulers, compass, split compass, compass of different lengths, split compass, other accessory tools, tool boxes including protractors, etc.). The tool of the present invention makes it possible to measure the radius and diameter of circles and arcs with very large radii and to draw such circles and arcs very easily and quickly without the use of accessories. Therefore, there is no need to rely on accessories. Similarly, the tool of the present invention makes it very easy and quick to measure the radius and diameter of circles and arcs with very small radii and to draw such circles and arcs without using accessories. it can.

  We hope that the geometric tool of the present invention will soon be available to millions of children around the world.
