Abstract

A Circular Easy-draw Flat compass is a training aid and stationery, and is used to draw a circle. The design of this compass is such that in making it the fixed and moving parts of the compass are completely removed and is created from only one circular page, and the other innovation in creating is that there is no need to measure the radius and any radials that the user wants, is specified.

Description

The description of the invention
A) Invention Title: A Circular Easy-draw Flat compass
B) Invention technical field: Training aid and stationery
(C) The technical problem and the explanation of the invention aims
C. l = Technical Problem: Since I have had a record of mathematical training in schools for 25 years, Repeatedly I've seen technical problems in using the current compass like the following:
Opening the axes and measuring the radius is difficult for student and generally, the size of the opened-axes is not as the wanted radius and has a measure error, to the extent dissuaded teachers to ask drawing circles e.g. with a 33 mm radius.
2. The intersection of the two axes of compasses would be loosen after several uses, and that causes to seperate the two axes while drawing and makes changes in radius so the circle wouldn't be uniformly drawn.
3. The sharp tip of the fixed axis makes cavity at the center of the circle.
4. Sometimes ,the sharp and needle-like of the compasses is turned to a dangerous game for students, It is seen that caused perforation and bleeding the hands or feet and even their faces.
5 .At the movable tip of the compasses is designed a pencil that would be shortened after a few uses, and changing them is impossible or very difficult, and a mechanical pencil is used in some other types of compasses, these leads are getting broken consistently and Students are constantly are putting leads or setting them.
6. Assuming that I do not consider any of the above problems, in fact in many cases of drawing a circle, the end point and the starting point of the circle is not the same, because along with rotating the tip of the movable axis, the fixed tip must be rotated in its place on the center of the circle.
7 .Due to the above problems, drawing is very time-consuming.
C -2 = Invention Objectives
It is so clear that my invention purpose of the flat compasses is, first of all, to solve the technical problems and, secondly, to serve at the country educational system , and ultimately to entrepreneurship, employment, commercialization and entrepreneurship.
D) A description of the condition of previous technical knowledge
The available compasses in the market are generally made of two axes connected on one side and a fixed axis and a movable axis. The using way of them is, at first, opening the tip of the two axes as much as the desired radius, and then placing the sharp pointed axis as the center of the circle and rotating its designed movable tip at the end of the pencil and drawing a circle.
E. l) Provide solutions for the existing technical problem:
In order to explain the solution to the existing technical problems, we must first find the root cause of these problems. In the existing compasses while drawing the circle , the fixed tip would rotate with the movable tip necessarily because they're attached, this means actually it's the fixed tip should be rotated to rotate the movable tip ,in the other word, the fixed tip on the center forms a circle with a zero radius and this causes these mentioned problems.
Therefore, in the flat compasses, it is thought as these two axes are completely separated, and in the true sense of the word, the fixed tip is fix and only the movable tip gets rotated.
E-2-A detailed, adequate and integrated description of the invention Before describing and explaining this part of the invention, it's necessary to explain and remind you that this compass is merely designed for drawing circles in different educational bases, and in this case, according to my research , the minimum radius is 1 cm and the maximum is 5 cm, and Generally these sizes are accurate, and occasionally and rarely there were questions from 15, 25, 35, and 45 mm radii. However, in my description, the radius is considered from 5 to 50 mm. It is so clear that these dimensions and precision can be changed if needed, and even can use different materials, and this description is only an example of the invention.
My flat compass is made of a transparent plex or talc circular plane with 11 cm diameter. On this plane, we seperate ten arces with 36 degrees and draw 5 diameters or radius of the circle with the equal distances ,then create a hole with a diameter of 0.7 mm at the center of the circle where is the fixed tip of the compass and the center of the conventional circles.
Starting with an arbitrary radius on it with the distances of 5, 15, 25, 35, and 45 mm, and then on the second radius with the distances of 6, 16, 26, 36, and 46 mm, respectively, on the third radius with the distances of 7, 17, 27, 37, and 47 mm, and on the fourth radius with the distances of 8, 18, 28, 38, and 48 mm, and the fifth radius with the distances of 9, 19, 29, 39, and 49 mm, and the sixth radius with the distances of 1, 2, 3, 4, and 5 cm, and on the seventh radius with the distances of 11, 21, 31, 41, and mm, and on the eighth radius with the distances of 12, 22, 32, and 42 mm, and on the ninthe radius with the distances of 13, 23, 33, and 43 mm, and on the tenth radius with the distances of 14, 24, 34, and 44 mm ,we create holes with a diameter of 0.7 mm, and the considered intervals (distances) is written under those holes (as shown in Figure 1, page 1)
In this way and such easily, the considered compass is ready and, meanwhile, writing the numbers under the holes is done as each radius is positioned at 9 o'clock (180 degrees of trigonometry). The numbers under it are horizontally placed to view and read the most comfortable position, this will make the user to start drawing the circle from this point (at 9 o'clock), so the best starting condition of the circle is due to experience the same point ,as needed, can be used for the fixed and moving tip of any available pencil or pen.
F) Explaining the shapes, drawings and patterns
Figure 1 is from page 1 is circle plane with a diameter of 11 cm, where there is a hole in the center of it, that is the fixed tip of the compass. Ten radii of 5 centimeters are plotted, and on each radius, some holes has been created that is the place of the movable tip of the compass, and the distance between each hole to the center of the circle is written below it and the user selects its considered radius from these units of each radius hich are written at the end of that radius . the central hole is surrounded by a small circle to better seen the center of plot.
G) Clearly and accurate explaination of the invention benefits
1. Solves all the technical issues and problems of previous compass; 2. Does not require a ruler to measure the desired radius; 3. Stationary and movable axes of any user's choice can be choosed; 4. Simple production. 5- The ability to use different materials in production 6- Cheap production 7-High commercialization ability 8- Excellent economic justification9- Ability to advertise other brands on the compass 10- Very easy and accurate use method
H) Explaining an implementation method for applying the invention
Suppose that we want to draw a circle of 3.5 cm or 35 mm in radius. To do this, we put a pencil in the center hole of the page, which specifies the center of the wanted circle. Turn the plane to the radius 5, 15, 25, 35, and 45 at 9 o'clock, Now insert another pencil in a hole above 35, the circle would be easily drawn by rotating the pencil in a circular clockwise direction .(it is better to hold the center pencil with the left hand and hold the second pencil with the right hand and necessarily both pencils should be perpendicular on the page and be hold from the above, and if you use two non-sized pencils, place the taller pencil in the center.)

Claims

Claiming the invention
Claim 1 : A Circular Easy-draw Flat compasses is made of a circular plane of an arbitrary material especially transparent talc or plex , with ten equal devided parts, and 10 radii is drawn in it, a hole in the center of the circle is created to insert the fixed tip of the compass and on each radius, there are holes with the specified distances with the written size underneath (as shown in Fig. 1, No. 1), the first radius on the intervals of 5, 15, 25, 35 and 45 mm, the second radius on the intervals of 6, 16, 26, 36, and 46 mm, the third radius on the intervals of 7, 17, 27, 37 and 47 mm and the sixth radius on the intervals of 1, 2, 3, 4, and 5 cm , and the seventh radius on the intervals of 11, 21, 31 and 41 mm, and on the eighth radius on the intervals of 12, 22, 32, and 42 mm , and the ninth radius on the intervals of 13, 23, 33, and 43 mm, and on the tenth radius on the intervals of 14, 24, 34, and 44 mm, this holes are for the moving tip of the compass to draw the circle with the desired radius. To draw a circle, use a pencil or pen for the center hole and a pencil or an arbitrary pen for the movable tip in the desired hole, which is the distance from the center of the same circle's radius. By rotating the second pencil around the first pencil, the circle would be drawn.
The innovation used in this compass is that the two standard tips of traditional compasses are removed and there is no need to measure the radius with the ruler, and each of the tip is chosen by the user.
