Description

Footwear product with opening and closing parts in midsole and manufacturing method thereof

The present invention relates to a footwear product and a manufacturing method thereof, in particular to a footwear product having a midsole with opening and closing parts, and a footwear manufacturing method using a midsole with opening and closing parts.

Roughly speaking, the method of shaping the upper in the shoemaking process is mainly divided into two methods: board lasting (board lasting, also known as lasting or climbing) and slip lasting. Among them, the clamp upper method is mainly used for the production of leather shoes and boots, and the last method is mainly used for the production of sports shoes and casual shoes.

In the lasting method, the upper and the midsole are mostly stitched together by sewing, and form a foot space for the foot to enter, and the last is built into this foot space to make the upper Stereotyped. Then, at the bottom outside this foot space, stick the sole against the midsole to complete the bottom molding. In the clamp-on method, the midsole is first fixed to the bottom of the last, and the upper is then wrapped around the last, and the bottom end of the upper and the periphery of the midsole are attached together by climbing, which can also make the upper close to the last After setting the shape, the sole is attached to the midsole to complete the bottom molding.

The clamp lasting method requires a lot of processes, and a shoemaker with a certain number of years can be engaged in the work that requires skilled craftsmanship such as front climbing, rear climbing and side climbing, which consumes more labor costs and relatively low production efficiency. However, for some shoe types, either because the last is difficult to insert from the foot space above the upper, or because of the aesthetic considerations of the upper being straight, the last manufacturing method cannot be used and the clamp upper manufacturing method is adopted. The present invention provides a novel method. The midsole structure can achieve another simple manufacturing method, without the need for professional machines or years of manual training, that can achieve the effect of the traditional clamping method.

The present invention provides a shoe midsole. The shoe midsole has an opening and closing component, and the opening and closing component can be a zipper or a devil felt.

The invention provides a shoe midsole. The shoe midsole has an opening and closing component. When the opening and closing component is fully opened, the shoe midsole is divided into two to become two completely separated half-piece midsoles.

The invention provides a shoe midsole, which includes: a midsole body with an opening; and an opening and closing component arranged along the opening to open and close the opening.

The invention provides a shoe midsole, which is composed of a midsole body and a zipper. The midsole body has an opening, and the zipper is arranged along the opening. Among them, the zipper includes a slider, a top stop, a bottom stop, and chain teeth. Wherein, the slider is flat, so that the thickness of the zipper is approximately equivalent to the thickness of the midsole body.

The present invention provides a footwear product, including an upper that matches the three-dimensional shape of the foot; a midsole that conforms to the shape of the sole and has a zipper; wherein the upper and the periphery of the midsole are combined to produce a foot A foot space into which the body extends. The upper and the midsole can be stitched together by sewing. The footwear product further includes a sole, which is tightly attached to the midsole outside the foot space; wherein, the sole can be attached to the midsole by using an adhesive in a step of attaching the sole. The footwear product further includes an insole which is stacked on the midsole in the foot space.

The present invention provides a method for manufacturing footwear. When a shoe upper is combined with a periphery with a zipper midsole, it becomes a semi-finished footwear product; a last can pass through the loosened zipper from the bottom of the semi-finished product , Into the foot space formed by the upper and midsole. When the last is attached to the midsole and the zipper is closed, the subsequent shoe-making steps of bottom molding and upper shaping can be carried out.

With the present invention, a new method for making shoes with a zipper upper can be realized, making the shoe making process more efficient and saving costs.

The opening and closing component referred to in the present invention refers to a buckle, zipper, devil's felt or the like, which is a component that combines an opening. The so-called opening can also be an open type, which is an opening and closing part that combines two separate objects, such as a jacket opening. When the opening and closing part is loosened, objects can pass through the opening; when the opening and closing part is tightly closed, the opening is combined to form a tight state. Since the zipper is the most well-known among them, the following embodiments take the zipper as the representative of the opening and closing parts for illustration.

Please refer to FIGS. 1A to 1B. The present invention provides a midsole 10 of a shoe, which includes a midsole body 11 and a zipper 12. The midsole body 11 has an opening, and the zipper 12 is arranged along the opening to open and close the opening. Figure 1A shows a state where the zipper 12 is closed tightly to close the opening. Among them, the zipper includes a slider 13, a top stop 14, a bottom stop 15, and chain teeth 16. Sometimes, in order to make the thickness of the zipper approximately equal to the thickness of the midsole body, the slider 13 may be in a flat and thin style, and does not need to have a pull tab and a cap. As shown in Figure 1B, the zipper 12 may have a structure without a top stop, and its slider 13 can be further separated from the midsole 10 when a certain force is applied. In addition, Figures 1A to 1B are for the convenience of explaining the structure of the zipper, and do not show the actual relative size relationship and position of the midsole body 11 and the zipper 12. For example, in conjunction with the shoemaking process, when the zipper 12 is fully opened, the midsole of the shoe may become two completely separated half-piece midsoles.

Referring to Figure 2, the present invention provides a kind of footwear 20, including an upper 21, matching the three-dimensional shape of the foot; a midsole 22, conforming to the shape of the sole, and having a zipper 23; wherein, the upper In combination with the periphery of the midsole, a foot space 24 for feet to extend into is created. The upper 21 and the midsole 22 may be sewn into one body by sewing, or other bonding methods may be used. Sewing methods can be divided into three-dimensional sewing and flat sewing. The three-dimensional sewing is as shown in Figure 2. The bottom edge 25 of the upper will cover the periphery 26 of the midsole, and then the foot space 24 will be inserted into the foot space 24 along the overlap of the periphery 26 of the midsole and the bottom edge 25 of the upper . Flat sewing means that the bottom edge 25 of the shoe upper and the periphery 26 of the midsole are attached to the same plane as the midsole 22, and can be placed on the sewing machine table. Sewing combination.

Please refer to Fig. 3, a last 27 can pass through the loosened zipper 23 from the bottom of the footwear product 20 to enter the foot space formed by the upper 21 and the midsole 22. When the last 27 is attached to the midsole 22 and the zipper 23 is closed, the upper 21 will tightly adhere to the last 27, forming a climbing effect, and then the shoe-making steps of bottom molding and upper shaping can be carried out. . The zipper 23 may have a structure without a top stop. When the zipper 23 is closed and finished, the slider can also be directly separated from the midsole 22 to make the sole relatively flat.

Even for the current shoe production process that has adopted the last (Slip Lasting) manufacturing method, the present invention is also helpful. Because the last is automatically loaded by manual or machine, because the upper and midsole are difficult to move after the last is inserted, if the position of the last is deviated, it is necessary to pull the last heavy industry. With the present invention, when the zipper is loosened, the last can be moved to the correct position in the foot space, and the zipper is closed after the positioning is completed, so that the midsole and the upper are tightly attached to the last to form a shape. Therefore, the existing shoes of either the lasting method or the lasting method can be modified to the zipper lasting method of the present invention.

In another embodiment, the midsole can also have both a zipper and a devil felt. When it is necessary to further climb the upper near the toe and heel, in addition to the zipper in the middle, the midsole has a structure of devil felt near the toe and heel. The inner lining of the upper part close to the toe cap and heel has a corresponding structure of devil felt, and this part may not be stitched with the midsole first. After the last enters the foot space and fits the upper and the midsole, after closing the zipper, pull the upper close to the toe and the heel of the shoe to the corresponding devil felt part of the midsole and combine it with the buckle to make the upper Presents a straight effect.

Please refer to Figure 4, the footwear product 30 of the present invention further includes a sole 28, outside the foot space 24 and the midsole 22 tightly; wherein, the sole 26 is a step of attaching an adhesive and middle sole The bottom 22 fits and fixes the upper 21. In another embodiment of the present invention, the sole 28 may be stitched and integrated with the midsole 22, or may be stitched and pasted.

Referring to Fig. 5, the footwear product 40 of the present invention further includes an insole 29, which is stacked on the midsole 22 in the foot space, so that the foot does not feel the presence of the zipper. Since the insole 29 is placed in the foot space and cannot be seen from the side of the shoe, Figure 5 shows the position of the insole 29 and the midsole 22 in the shoe with a dotted line, and a dotted chain line shows a perspective view area to mark In addition, the insole 29 and the midsole 22. In addition, the zipper of the midsole 22 may have a flat and thin style. For example, the thickness of the slider, top stop, bottom stop, and sprocket of the zipper are approximately equivalent to the thickness of the midsole shoe material, and the slider can be flat. , You don’t need to have pull tabs and caps.

In summary, the present invention provides a shoe midsole and its footwear products, as well as a new shoe manufacturing method, which makes the way the last enters between the upper and the midsole different from the past, thereby reducing labor costs, and more Efficient shoemaking process.
