Front Opening Shoe Design -- Design Features

In addition to shoes with ears and tongue shoes, there are also a large class of shoes called open shoes.

Because the opening position is different, it is subdivided into two forms: the front opening shoe and the side opening shoe.

Opening and closing is a pair of contradictions. The closed shoe has small opening and closing functions. By opening the opening in the back midline position, the opening and closing functions of the shoes can be increased, and the front opening shoes are formed.

Since it is a front opening structure, the front opening front part and the two side parts are connected into a whole, which is the characteristics of the front opening shoe.

The width of the front opening day can vary. The parts on both sides of the opening are very similar to the shoe ears, often called shoes ears, but the structure of the front opening shoes and the ear shoes is completely different. The ears of two ears of the inner ear or the outer ear are separated, while the front opening shoes ears are connected.

Generally speaking, the medium width open pattern is referred to as the open shoe, and the shoe with wide opening is called wide opening shoes. The narrow opening shoes are called narrow opening shoes.

See color F series.

The color picture F-l is a front opening leisure shoe with eye cover. It uses a Velcro instead of a shoelace. The front end is designed with a T shaped Baotou, and the mouth and shoe tongue are flip flapped, and the shoe is wrapped with foam.

The color picture F-2 is a lady's light front opening shoe, with the opening near the toe end, which is very convenient to wear. It can improve the foot holding ability of shoes by fastening the shoelace.

The color picture F-3 is a narrow opening shoe. The front end is equipped with the front Baotou, the shoe bag has the foam cotton, belongs to the leisure shoes style.

The color picture F-4 is special. The front cover has eye cover, but it only plays the role of decoration. The shoe eye position is in the inner side of the eye lid.

There is no break between the front and back of the shoe. The design of the half panel is a very simple way to handle it.

The color picture F-5 is a saddle style man's shoe with a front opening designed on the back part.

The shape of the middle part is similar to that of the saddle.

The color map F-6 is very like an inner ear type shoe, but the two shoe ears are linked together with a strip along the mouth.

A careful observation of the shoe ear parts is made in order to save material, but the front opening structure is adopted in the structure.

The color picture F-7 is a super long shoe. The front band looks very long. But by observing the metatarsophalangeal joint, we can see that the position of the front opening is relatively close.

However, because the front opening is very narrow, it is necessary to design the switch.

Characteristics of 1. last type

For men and women, the front opening shoes should be designed with male and female prime last.

Because the shoes on the sides of the opening are usually tied up, or the auxiliary parts such as rubber band, buckle and shoe drill are connected, a closed cavity is formed. Therefore, the circumference of the shoe last can not be too small to ensure the comfort when wearing.

2. features of upper structure

The location of the front opening position of leather shoes is generally designed at V point. The front opening position of sports shoes is usually taken at V point, and the front opening position of leisure leather shoes is more flexible, and it can also be taken between V or V J.

The front opening shoe is the structure of the tomorrow door, and the position of the door is relatively close.

The shape of the front opening shoe has leisure and sports style. It gives people a feeling of comfort, freedom and liveliness, and some shoes are very rough.

The shape of the front opening occupies a major position in the appearance of the shoes.

In the structural design of the front opening shoe, the position of the back midline directly affects the design of the opening width.

For this reason, the width of the openings should be determined according to the requirements of the styles, and then the different seesaw lines should be used to control the width of the openings so as not to affect the preparation and opening of the templates.

As shown in figure 1- 7-1, the design of the middle width opening is controlled by a pair of take off line (A1 line). When the narrow opening is designed, the switch line (A2 line) is used to control the design, and the positioning take off line (Ao line) is used to control the opening width.

Take off line refers to the back of the front line in the different state of taking off.

 

By comparing the control of three different opening widths, it is found that the positions of the three midline are in different states.

The positioning and picking line is called Ao line for short. Its position is the highest, but its extension line is the lowest, which is used to control the wider opening design.

Conversion to take off line referred to as A2 line.

Its location is the lowest, but its extension line is the highest, which is used to control the narrow opening.

The counterpoint line is referred to as the A1 line. Its position is in the center, so its extension line position is also centered, which is used to control the design with medium opening.

The width of opening can be divided into three types: wide opening, open middle opening and narrow opening, so as to facilitate finding corresponding positioning, aligning and converting three fetching lines, which is conducive to the smooth design of structural drawings.

In experience design, the width of the opening is controlled by data, though very simple.

However, learners can only accept passive status and can not open their minds and design independently.

If the structural design is adopted, the width of the opening can be freely chosen. There will always be a corresponding midline to control the effect of no plan, so that we can develop our innovative thinking boldly and design more and better products.

Characteristics of 3. components

Because the parts on both sides of the opening are similar to the shoe ears, the length of the shoe set will change with the number of shoes.

Generally speaking, the tongue length of the front opening shoe of the front opening shoe belongs to the dark shoe tongue, which is similar to that of the front shoe.

Inner ear shoe tongue.

It is a kind of "fill" up the tongue.

But the structure is different. The inner ear type shoe tongue is mended under the back shoe ears, and the stitch of the shoe tongue is covered by the front cover.

The front opening tongue is added to the front openings. The stitches of the shoe tongue can be clearly seen.

It is obvious that the trails of the car are also designed, as shown in figure 1-7-2.

 

4. characteristics of inlay connection

The structure of front opening is usually designed on the front side. This type of shoe is designed with a front pressure connection. The front opening can also be designed in the middle of the back. This kind of shoe usually adopts the insertion relation between the two ends of the middle pressure. If the front opening is designed on the eye cap, the upper pressing down connection is generally adopted.

This can highlight the structural features of the front opening type.

5. requirements for opening molding

Although the shape of the opening is wide and narrow, the outline of the opening should be parallel to the back line. The appearance of the shoe feels that the structure of the shoe is relatively stable.

The wider opening can be treated by the folding process when dealing with the open edge line, and the narrow opening can be treated by the mouth process.

Rough style openings can be directly cut and trimmed.
