Design Of Inner Ear Shoes -- Structural Design Of Men'S Two Shoes

Analysis of men's two quarter shoes (see figure 1-2-9) should be done with two women's head shoes, so that new knowledge can be quickly found.

 

1. structure

The structure of men's two section shoes is the same as that of women's two quarter shoes. It also belongs to the inner ear structure of ear shoes.

That is to say, the design of the two toe shoes is the same, but the difference is only the difference of the last shape and the style of the parts.

2. last type

The design of male prime shoe last is adopted.

This is a shoe last for the production of popular products. The last type has a metatarsal circumference than the foot sole type (3. 5mm). It has a certain ability to hold feet. The shape of the last shape is o.5mm larger than that of the foot, and it is suitable for producing all kinds of bandage shoes, drill shoes, rubber shoes and so on.

The main dimensions are shown in table 1-2-2.

3. components

The main components are the front and the back, as well as the tongue and the safety skin, which are also four kinds of five pieces.

Pay attention to the change of the shape of the safety leather, and design the curve shaped insurance cover with the overall modeling requirements.

Because men's shoes VE line is longer than women's shoes, 5 eye positions should be designed.

4. inlay

The connection between the main parts is that the front wall is pressed behind, and the front end is pressed with stubble.

The shoe tongue parts are pressed under the two shoe ears, and the safety leather is pressed on the upper end of the back seam.

5. special requirements

Although the two heads of men and women are the same in terms of structure, last type, part, and splicing, the design style of men's shoes and women's shoes is 4 in the District, mainly in the shape of the last body and the change of the outline of the parts.

One of the more prominent lines is the front and back sides of the line, men's shoes require a steady, rigorous and dynamic.

Therefore, the two sides of men's shoes are more plump and thick.

Because of the changes in the shape of the two sides of the Chinese Gang, the problem of interlocking can be drawn out.

How do we control the width of the two wings?

See picture 1-2-10.

As a whole, one wing of a component is inserted into the door of another component, and the width of the door is about 1/3 of the overall width.

Obviously, if we analyze the width of the half side from the location of the midline, it should occupy 1 / 3.

Whether the whole or the half side is analyzed, in the content of the width of the door, the design width of the two wings should be removed. It should also include a width width (16mm), three hem width (3 x 5mm), and a multiple width of 4mm (about 4mm).

Therefore, when controlling the width of the door, 1/3 should be included under the condition of 35mm, as shown in figure 1-2-11.

 

As shown in the figure, first extend the back midline of the front, then find the midpoint of the two wings HF F2.

Cross the F2 point as the vertical line of the extension line of the back midline, and the intersection point is F3 point.

The Fz point of the bottom port is extended to 35mm for about F4.

Intercept 1/3 on F3 F4 to locate Fo points.

That is to say, the width of the door is controlled by the Fo point, which ensures the mutual fit between the two wings.

If two can not be interwoven, it will inevitably lead to waste of raw materials. This model can not be put into production. This is also a design with unreasonable structure.

Increase the 3mm by 0 points, then connect to the Fo point to form a width control line.

The Fo point is the biggest difference between designing two pairs of shoes for men and women. The two wings of women's shoes stretch down and the mouth naturally grows bigger, so there is no need to find Fo points.

Note that when the Fo point is applied, if the Fo point exceeds OQ line, it should be used on the OQ line. This situation is not impossible to draw, but to form a "gourd" out of shape.

In the two section of the shoe line, there are three lines in front of the front car, one by one, one by one, the other by the same line.

1. the design of the former Gang

The front design is shown in Figure 1-2 -12.

 

Draw the outline of the half panel, connect 4 basic control lines, and make the natural angle VOV'by compasses.

Connect the vJ line and extend the A point from the front end to A.

Point, A.

V'is the front line of the front team.

The length of the two wings is F1 point, and the midline of HF1 is the perpendicular line of the extension line of the back midline, intersecting at F3 point. F2

From the point of F2, we extend the 35mm point to F4 point and take the upper 1/3 of F3 F4 length to set Fo point.

The vertical line of the OQ line is controlled by F1 points to control the outline of the two wings.

The O'point is set as the reserved amount of the tensile deformation of the door.

Connect the O'Fo line and extend the verticals along the Fi point.

Go through the V'point to make the vertical line of the front midline.

The front contour is designed in the auxiliary line V'to O' to Fo to F1.

Also use the V Post's vertical line to standardize the outline of the door.

The design of the 2. Gang

The structural design of three section shoes is shown in figure 1-2-13.

 

 

The inner ear shoe tongue design method is the same: first take the reference length VE, add 10 ~ 12mm stubble at the front end, add 6 ~ 7mm at the back end.

The width of the front line is reduced to 5mm after controlling.

The rear end of the shoe tongue is arc-shaped, and the front end presses the stubble to mark the inclination angle.

The design of the safety leather is curved: a vertical middle line, the basic height of the insurance cover is 10 to 12mm, and the top back is 8 to 9mm.

The basic length is 20 ~ 22mm, and the upper part is 30.

The tilting angle is a reverse mark, and the lower segment is rectangular after being taken to a curve, which is similar to the half braces.

This kind of insurance cover is very special. It is used for men's two quarter shoes or three quarter shoes. The purpose is to match the steady style of shoes.

After the design of the front, back, tongue, and insurance skin, the structural design is completed.

The addition and opening of the bottom and the difference between the inside and outside is the purpose of making the template.

In general, when drawing the design chart, do not add the amount of the bottom opening, so that you can see clearly the relationship and proportion of the parts on the last surface, and will not be affected by the increase of the bottom.

4. bottom treatment

After the completion of the structural design, check carefully, do not appear careless, and finally add the bottom stretch.

There is a fixed pattern for adding and releasing the bandage. Men's shoes are added in sequence from 14mm to 15mm to 16mm to 17mm, from the front, metatarsophalangeal joints, waist, heel and so on.

Note that the back line is connected to the arc, and the bottom can not be oversized or too small.

According to the difference between the inside and outside of the original sample, we make the line of the mouth.

Through the above two design examples, we can know the principle and application method of positioning and taking off.

Positioning and taking off is a simple and practical way to take off. Of course, with the change of shoes, the position of picking up and taking off center will also change slightly, though not as direct as the inner ear shoe, but it is also very simple, and will be introduced one by one in the following chapters.
