Design Of Outer Ear Type Gallbladder Shoes

The design of the outer ear type gallbladder shoes is roughly the same as the design of other gallbladder shoes. Because the difference between the front point and the inside of the shoe ear itself exists, the design of the shoe gall should follow the principle of "looking for the outer side and looking for the arms inside the outside."

1. finished product drawing

As shown in figure 2-3-10, the shoe ears are joined to the half girth. Because the shoe ears are small, most of the tongue are exposed, so the tongue is kept open.

Use square head last, shoe toe is wider, the width of shoe gallbladder takes 3.4 of the head width.

The rear part has the back package and the parts echoes with the broken line of the shoe ears.

2. structure design drawing

The structure design of the outer ear type gallbladder shoes is shown in figure 2-3-11.

First design the parts of the shoes, shoes, tongue, shoe, broken line, back pack and so on, then design the shoes gallbladder according to the three step method.

The first step is to design the original shoe gall according to the pattern requirements of the finished product, set the width of the shoe gallbladder on the front width line and connect the auxiliary line.

The dividing line of shoes and gallbladder changes under auxiliary line.

Extending forward and parallel to the half panel toe ends, extending back to the inside and outside positions of the shoe ears.

After the shape is smooth, the dividing line of the shoes and gallbladder is determined, and the shoes and the shoes and ears are integrated into one body.

The shoe dash line and the original back middle curve form the original shoe gall, and the original shoe shoe is made as a duplicate board.

The length of the replica board can be taken to V'.

The second step: make the back midline of the shoes and parts to make the conversion and take the line, extend the EV line as the middle line of the back of the shoe.

The J2 point is found by intersecting the arc between the J point and the midline.

The J2 point is the conversion length point, and the actual length should be found to determine the length difference.

And take the length difference of the 2 parts to fill the shoes and set the J3 point.

The third step: design the outline of the shoe bladder parts, and use the replica board to design the shoes and gallbladder parts in the straight line of the back.

First, the points of the replica board are aligned with the J3 points on the back midline, and Jo points are determined to ensure that the width of the shoe gallbladder remains unchanged.

Then draw the outline line of the shoe bladder parts, and the rear part should be connected to the shoe tongue position.

The location of the intersection with half girth is 01 points.

The curve after 01 points naturally connects to the 0'point of the shoe ear.

The front part is drawn according to the replica curve, and the length of the upper and lower lengths (AJ length and A'J'o length) should also be controlled.

After the graphic design is completed, the difference between the inside and outside of the line and the outline of the shoe should be concentrated.

Also set out 02 points, 01 and 02 points and the location of the lock mouth is the rules of the shoe ears.

Finally, the contour of the bottom rib and the difference between inside and outside are designed.

3. sample preparation

The basic template of the front Gang is shown in figure 2-3-12.
