JPS6027673Y2 - Three-dimensional drawing template - Google Patents

Description

[Detailed explanation of the invention] Most three-dimensional drawings use perpendicular lines, diagonal lines at 30 degrees left and right, and ellipses, and many ellipses are arranged on the same line.
The rounded corners also use ovals.

Therefore, drawing an ellipse on the same line or in the same direction will affect the quality of the drawing.

A drawing with ellipses drawn in different directions in the same direction is not something that has been seen.

Generally, a triangle ruler is used to draw left and right diagonal lines and perpendicular lines, but since these three lines are always related, it is difficult to change the position of the triangle ruler, and it is difficult to draw lines on the line. I have to draw many ellipses in the same direction, and it takes a lot of time and effort to align their centers.

An ellipse ruler is used to round the corners, but it is difficult to see the intersection of the small ellipse and the straight line, making it extremely time-consuming.

Therefore, various templates have been released so far, but they are all difficult to use, and many of them are broken.

There are some things you can't write without using a drafter.

This invention was devised in order to solve the above-mentioned inconveniences, and as a result of prototype testing, it was found to be the best in terms of ease of use, drawing speed, and quality compared to conventional ones, and it is very popular among not only drafters but also printers. This is a convenient 3D drawing template that can be used with a ruler as well.

To draw a three-dimensional diagram, a diagonal line extending 30 degrees left and right and a perpendicular line are basically used as the axis, and in the case of an ellipse, this axis becomes the short axis.

A line perpendicular to this short axis is the long axis, and a 60 degree line perpendicular to the 30 degree line is required.

The two are always related.

A horizontal line is used as a ruler for a perpendicular line.

Also, as a basic rule, an ellipticity of 35 degrees and 16 minutes is generally used.

The present invention will be explained based on the drawings, with the right 30 degree line being the X axis, the left 30 degree line being the Y axis, and the vertical direction being the Z axis.

The W plate 1 has a Y-axis and an X-axis with an opening degree of 120 degrees, which are inclined 30 degrees to the left and right at the top with respect to the bottom, and in the middle thereof,
A 60 degree chevron is arranged, and scales are attached to the X and Y axes based on the intersection of the chevrons.

The left end is the Z axis, which is perpendicular to the base, and is graduated from the base, that is, the horizontal line.

The 60 degree line and the horizontal line are the long axis lines on the drawing.

Others are attached, and using the margin, several 35 degree 1
A round guide, cylindrical shape is a 55 degree oval guide for the root, a perfect circle and a body oval guide for the part number, and IP on the base,
It has a conversion scale for ID.

The elliptical plate 2 has several elliptical guides 4 arranged in 35 degree increments on an axis parallel to one side, and a rectangular guide 5 for hexagonal bold and nuts arranged at the upper end. It is an equilateral triangular plate.

The corner plate 3 has several diamond-shaped corner guides 6 arranged on an axis parallel to one side using ellipses with size increments.
It is an equilateral triangular plate with an arrow guide 7 indicating the direction at the top and a cylindrical equally divided scale 8 at the bottom.

Next, we will explain how to use this.

By simply moving the axis and long axis from side to side using the W plate 1, it functions in the same way as a conventional triangular ruler.

Furthermore, since each scale is graduated from the long axis line, the next long axis line can be drawn by setting the pencil to the required size and moving the W plate 1 or the ruler.

If the elliptical plate 2 is aligned in the X and Y directions, which are marked respectively, an elliptical array can be formed on the surface in those directions.

The Z axis may be used together with the corner plate 3.

The rectangular guide 5 can draw straight parts on four sides of the six straight sides of a hexagonal bold nut, excluding the major axis direction.

If the corner plate 3 is also aligned with the X and Y directions, which are the markings, the two intersecting lines of the surfaces in those directions will be easy to see, so the corners can be easily rounded.

When the arrow guide 7 is combined with the W plate 1, marks can be made in six directions.

The cylindrical equally divided scale 8 is used when drawing a three-dimensional pattern on the cylindrical part.
As a scale for the line spacing, if you align the lines with the same symbols on the W plate 1 and divide them one by one at the center, you can draw symmetrical lines.

As described above, by using the three plates in combination, the drawing speed becomes even faster and the drawings become more beautiful.

Of course, if you use a large-diameter ellipse or a different ellipse, use W.
It can be used along Plate 1.

Also, in this proposal, the IP size is 1:0.82, but if the scale and oval diameter are the old size of 1:1, the IP size is 0.82.
Useful.

According to the results of prototype testing, we can expect the fruit to have several layers of peel compared to conventional products.
