Design Of Front Opening Gallbladder Opening Shoes

The front opening type gallbladder shoes are very common in sports shoes. The width of the half opening is between 12 and 15mm, but the width of the opening of the shoes varies greatly, depending on the style requirements.

1. finished product drawing

As shown in figure 2-3-6, the opening width of this shoe is relatively narrow, the technology of trimming is adopted, and the mouth of the shoe is turned over.

The shoe is intended to stretch forward to reduce the length of trimming.

The shoes and the shoes and ears are integrated into one body, with motion design elements.

The side arms of the shoes are relatively large, and are suitable for designing various signs (logo).

2. structure design drawing

The structure design of front opening type gallbladder shoes is shown in figure 2-3-7.

First, the opening structure, shoe ears, shoe eye positions, shoe ends, rear heels and other components are designed, and then the shoes and gallbladder parts are designed.

The design steps of the shoe gallbladder are the same as the whole tongue type opening shoes.

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

Connect the JoO'line to the auxiliary line, where the 0' point controls the width of the shoe ear.

The line of shoes and gallbladder changes under the JoO'line.

Before the Jo0 line 1 / 2, the shoe gallbladder line is convex, forming a concave line after the Jo0 line 1 / 2. It extends parallel to the AJ line and extends back to the width of the shoe ear.

In the shape of Shun Yue Yue, the shoes and gallbladder should be determined.

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: to make the front line of the back line of the shoe parts is relatively narrow, make the switch to 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.

Use the replica board to design the shoe gall parts in the straight line of the back.

First, the J point of the copy board is aligned with the J3 point on the back midline, and the Jo'is ensured to keep the width of the shoe gallbladder unchanged.

Then draw the outline line of the shoe parts like the shoe covers, and the parts that are not long enough to be linked up.

The front section can be used as a parallel line to control the upper and lower lengths (Aj length and A'jO length).

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.

This kind of processing is like dealing with the shoe, only making a difference between the concave arc.

Complete the design of shoe tongue and trademark logo.

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

The length of the shoe gallbladder will be less than that of the half girth when it is connected to the shoes, and it will still be inserted with the method of stretching the bottom edge, which is the same as that of the cover.
