Front Opening Shoe Design -- Women'S Shoes Design

The following is to select a group of front opening shoes with different widths for the design, and grasp the application of the front midline.

1. finished product graph analysis

(1) the structure of the women's shoes is a front opening structure (see Figures 1 - 7 - 3).

The location of the door is fixed at V, and there are 4 eyes on the shoe ears. The length of the shoe ears is about 50mm, and the first eye position occupies only half of the eye spacing.

 

(2) the last type is a female prime last.

(3) the components include four parts, the front, back, tongue and rear reinforcement five.

(4) insert the front press, press the back, press the back bar to press the middle seam, and the shoe tongue is placed underneath the front opening.

(5) the opening width is moderate before the special request, and the position of the opening is controlled by using the opposite position take off line.

2. structure design drawing

(1) the design of the front opening and the front Gang should be carried out on the A. line and extended.

The front opening line is a line parallel to the VE line, and the shoe ear should not exceed the extension line of the A1 line, otherwise it will cause the overlap of the shoe ears.

As the distance between the A1 line and the VE line is angular, the longer the shoe ear is, the larger the distance between the two wires is, and the wider the front opening is.

You can shorten the length of the shoe ears with the hope of opening slightly narrower.

The intersection point between the Ai line and the EP line is the parallel line of the VE line, which is the basic width of the front opening.

The parallel line spacing lOmm is used as the eye bit line.

The V point is the vertical line of the eye bit line.

Starting from the foot point, half the eye position is cut back, and the first shoe eye is determined. Then 3 other shoe eyes are intercepted one by one, and the length of the shoe ears is finally determined.

Find the P'point, from shoe day, shoe ear, P' point to qpoint to make the shoe contour.

The front opening line is only a part of the shoe contour line, as shown in figure 1-7-4.

 

As shown in the picture, the shoe ear distance to the Ai line is more than 5mm, considering the requirement of the folding edge.

The starting point of the broken ear position is equivalent to the position of the shoe ears, the distance from the eye line 12mm, and the design of the break line of the front arm and the Hi point at the bottom.

Take the arc line shape of the break line, design the most prominent radian near the OO line, and determine the 07 points of the center.

The position is taken to handle.

Make a pair of H1O'H2, and make H1O'H2 = AoO'A1.

Connect the front contour of the bottom.

(2) the design of the rear group has the shoe contour and the front side break line, and the contour line of the rear support is also determined.

(3) the design of tongue and tongue has a set rule and can be designed independently.

In order to compare the shoe tongue with the front opening, this picture is designed in the front opening position.

The basic length of the tongue is based on the length of the opening. The front pressure is 12 to 15mm, and the rear end is 6 to 7mm.

The width of the rear end to the pseudo line position should be included, including the width of the opening, and the width of the front end should be 6 to 8mm below the first eye position.

When designing the shoe helix profile, the front end is also designed to be arcs.

Finally, the front and rear sides of the front line are respectively made to distinguish the difference between the inside and outside.

3. sample preparation

First prepare the marking board, see figure 1-7-5.

 

As shown in the figure, the shoe tongue is designed inside the upper, which helps to control the contour of the front opening.

Then make the basic template, see Figure 1 - 7-6.

 

As shown in the figure, the markings on the front shoe are the rules of the shoe tongue, and the markings on the tongue are controlled by the door.

The solid line in the picture is the outline of the basic template, and the dashed line is the amount of processing added to the opening material.

Finally, draw the shoe template, see 1-7-7.

 

Taking into account the integrity of the opening position and the rear side, the 12mm position is designed in front of the door.

There is a stubble quantity between the front and back sides, and the tongue is left with a punch.

   

(two) the design of front opening narrow type women's shoes

Narrow the front opening and narrow it to a knife die. The width of the opening is about 3mm.

Such a narrow width, without the margin, should be treated along the mouth.

1. finished product graph analysis

(1) the structure of this woman's shoes is a front opening structure. As shown in figure 1-7-8, the location of the door is fixed at V point, and there are 4 eye positions on the shoe ears. The first eye position occupies only half of the eye spacing.

The front break line is closer, and the back is equipped with a longer back pack.

The process of shoe opening is along the mouth, without the amount of hem.

 

(2) the last type is a female prime last.

(3) the components include five parts, the front, back, back, follow, and tongue, six.

(4) insert the front side, press the back, press the back and press the back, and the shoe tongue is laid under the opening.

(5) the width of the special opening is 3mm and the method of conversion is adopted.

The front arm is disconnected at about AH 2/3 of the bottom port, and the rear package is longer, reaching the waist position.

2. structure design

(1) the front opening and the front part are designed to be converted to the A2 line, and the parallel line with the width of 3mm is opened. After crossing the EP line, the shape of the shoe ear is directly designed, and the contour line is connected with the shoe mouth.

13mm was taken from the eye line and 4 eyes were designed.

When the opening is wider, the margin of eye line should be reduced to prevent excessive hypertrophy of the ear. When the opening is narrow, the margin of eye line will return to normal.

Take the 12mm from the false line position and make the break line of the front side.

Take the nearest position from the 0 point of the line to take the center of O.

Make a switch to H1O'H2 and make H10'H2= AoO'A2.

The bottom line increases the length of the 1/3 to make the contour line of the bottom of the front support, as shown in figure 1-7-9.

 

(2) the design of the rear Gang is confirmed after the confirmation of the broken line and the shoe line.

The back pack and the position are divided in the range of the back Gang, and the shoe tongue parts are designed.

The width of the mouth is about 14mm, and the length of the shoe is lOmm.

Make the difference between the bottom and the outside of the front and back.

3. sample preparation

First prepare the marking board, see Figure 1 - 7-10.

Then make the basic template, see figure 1-7-11.

 

As shown in the figure, the dotted line in the graph represents the amount of work to be produced.

Finally, the shoe template is similar to that of the front opening middle width female shoe, as shown in figure 1-7-12.

 

The width of the front opening widens, and the positioning and taking off angle can be directly positioned at the front end of the opening.

1. finished product graph analysis

(1) the structure of the women's shoes is a structure with a front opening. As shown in figure 1-7-13, it looks very much like a woman's shallow shoe, but the two sides of the door are relatively high and still belong to full shoe.

The opening of the door is fixed at V point, and the front opening is connected with rubber band on both sides, and a shoe drill band is on the rubber band.

Shoelace has both decorative function and increased ability to hold feet.

Take the stilt angle at the front opening end.

 

(2) the last type is a female prime last.

(3) the components include five pieces of front, back, rubber, shoelace, and safety skin six.

Shoes need to be supplied with shoes to assemble on the rear side.

(4) insert the front opening to press the rubber band, the front side presses the back to help, the shoelace presses on the break line.

In traditional design, shoes are often used to cover up the break line. Attention should be paid to nail nails and shoelaces when shoelaces and shoelaces are used.

Now the usual way is to open the incision with the dark nail method, shoelace into the opening and then stitch.

If the dark nail method is used, the position of the shoelace should not be broken, or the strength will be reduced.

(5) in special requirements, the position of the car shoe lace is 14mm from the shoe's mouth, and the shoe's crossbeam position is based on the shoe 14mm.

As the shoelace is pressed on the rubber band, the design should be increased by 3mm.

The shoelace is 5 to 8mm away from the rear end of the rubber band.

The center position of the shoelace is the same as the position of the crossbeam of the shoe drill. It is also 14mm; the effective length of the shoelace is 30 to 35mm beyond the center hole position, and the center hole position is taken up from the 5mm spacing to get 4 holes.

Attention should be paid to selecting the width of the inner diameter of the shoe, which is greater than the width of the shoelace 1 to 2mm.

2. structure design drawing

First, the shoe contour is designed, and then the rubber contour is designed. The length of the rubber band is less than the turning point of the shoe ear.

Then the shoelace position is designed, which is less than 5 to 8mm of the length of the rubber band.

Design the rear end line, take the straight line, higher than the rubber band 3mm.

Then design the front end line and take the straight line.

Fix the 14mm position below the shoe to mark the point. The shoe is used to tie the shoelace, and the outer arms are used for spiking shoes.

The length of the end of the shoelace is 30 to 35mm from the marking point, and 5 drill holes are evenly allocated.

Finally, make the difference between the bottom stretch and the inside and outside, see Figure 1 - 7-14.

 

3. sample preparation

First prepare the marking board, see figure 1-7-15.

 

The basic template is 1-7-16.

 

As shown in the figure, the rules on the front and back indicate the position of the shoelace and the shoe drill.

The basic pattern of the rubber band has the same amount of stubble as the opening plate.

The broken line of shoelace is the amount of hem added to the opening material.

The shoe model is shown in Figure 1 - 7-17.

 

As shown, the two section shoe lining is adopted.

The rubber band should be lined with rubber strips under the rubber band to prevent the rubber from being stretched and deformed.

One of the shoelaces is a hint. When producing, the shoes are sewn together on a piece of Lippi, and then cut and used separately.
