JPH01227702A - Sole fitting part construction for french seam upper - Google Patents

Abstract

PURPOSE:To use a French seam upper and to make footwear into one having even the merit of a Goodyear Welt type footwear by joining-planting a rib member on the lower surface of a surface corresponding to a middle sole of the French seam upper. CONSTITUTION:A sole surface forming part 71a and an instep side surface forming part 72a are integrally formed by a cutting piece in approximately U shape, and a French seam upper 7 to fix a plug member 10 to it is used. A rib member 11 is plant-fixed along the full periphery or partial periphery of the sole surface forming part 71a, and a thin leather 12 is suture-linked to a rake sewing thread 13 to the rib member 11. Further, an internal article 14 is arranged in a space surrounded by the rib member 11, next, a face sole 15 is arranged in overlapping, and it is outgoing-sew-fixed to the thin leather 12. As a result, since a feeling of fatness can be obtained by the footwear to use the above-mentioned French seam upper 7, it can be made abundant in a flexibility and the face sole 15 is joined to the thin leather 12, the intrusion of water can be prevented, and since the insertion of the internal article 14 can be executed, an impact absorptivity at the time of walking can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a shoe sole structure for a bag-stitched upper to which the Gutteyer-welt shoemaking method can be applied.

<Prior art> As shown in Fig. 6, as shown in Fig. 6, as shown in Fig. 6, as shown in Fig. 6, the forming part of the bottom (la) and the upper side are formed by two U-shaped upper pieces. The forming part (1b) is integrally formed, and the plug member (2) is attached to it by mocha stitching (
Moka sewing thread (5)) is used to form a bag-like upper (3), and the bottom of the upper is brought into contact with the outsole (4), and the periphery is sewn with matsuke stitches (matsuke sewing thread (6)) to attach the bottom. There are two known methods.

<Problems to be Solved by the Invention> However, such conventional bag-stitched shoes wrap the foot in a bag-like manner, so while they provide a good fit and have excellent flexibility, they have the following drawbacks: I had a problem like this.

That is, in shoes using such a bag-shaped upper, there is no rib on the bottom surface of the upper (3), so the sole cannot be sewn by scooping thin leather during the process. Therefore, the so-called Gutdeyerwelt type bottoming cannot be used as a structure.

As a result, the outsole (4) is directly joined to the bottom surface of the upper (3), that is, the part corresponding to the midsole, making it easy for water to enter, and the thin contact surface reduces shock absorption when walking. It has the disadvantage of being inferior.

Therefore, in view of the above-mentioned conventional problems, the present invention makes it possible to attach a Gutsdeyer welt type sole to a bag-stitched shoe, thereby making the most of the advantages of bag-stitching.
The sole structure of the bag-stitched upper combines the advantages of Gutdeyer welt and shoemaking methods.

<Means for Solving the Problems> For this reason, the structure of the shoe sole according to the present invention is such that the bottom surface forming part and the upper 1-1 surface forming part are integrally formed by a substantially U-shaped cut piece. In a shoe bottom opening structure using a bag-stitched upper to which a plug member is fixed, a rib member is erected and fixed along the whole or part of the periphery of the bottom forming part, thereby making it possible to combine fine leather with fine leather. The bottom of the bag-stitched upper is characterized by the fact that it allows for scoop-stitching.

<Function> According to the shoes using the bag-stitched upper according to the present invention, the advantages of the bag-stitched method of providing a good fit and excellent flexibility are exhibited, and at the same time, the upper bottom and outsole are made of fine leather. Since they are joined via scoop stitching, it is possible to prevent water from entering, and since it is possible to insert inner items, the shock absorption properties when walking are improved. Furthermore, it is also possible to insert a shank that is large enough to support the load and maintain the shape of the arch of the foot, and to absorb shock when walking.

<Example> Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows an example of the structure of the sole of a shoe using the bag-stitched upper according to the present invention, and (7) shows the bag-stitched upper, which is made of a substantially U-shaped Chinese cut piece. A bottom part (71) and a middle side part (72) are formed in one body, and a plug member (10) is sewn thereon with moka stitching (moka sewing thread (9)) to form a bag shape. (11) is a rib member erected and fixed to the bottom surface (71) of the upper (7);
12) is a scoop sewing thread (scoop sewing thread) on the rib member (11).
13)) Fine leather stitched and connected, (14) upper (
(15) is inserted into the inner space of the rib member (11) on the bottom surface (71) of the
2) and an outsole which is disposed on the outer bottom surface of the midsole (14) and is connected and fixed to the fine leather (12) by a raised stitch (raised sewing thread (19)).

Note that (16) is a shoe last used in the shoe manufacturing process.

Next, the method of attaching soles to shoes using a bag-stitched upper having such a structure will be explained.

First, in the main cut piece (18) for cowhide shown in FIG. 2.3, a bottom surface forming part (71a) corresponding to the midsole surface and an instep side surface forming part (72a) are integrally formed. Note that the imaginary line indicated by the - dotted chain line (71b) is the inner edge of the outer peripheral edge of the bottom surface forming portion (71a). Next, a substantially U-shaped rib member (11) that is open toward the heel is attached and erected inside the bottom surface forming portion along the outer peripheral edge line (71b).

The rib portion (11) is made of cloth, leather, plastic, etc., and is sewn or glued to the bottom surface forming portion (71a).
) is firmly fixed.

Next, while bending and forming the main cut piece (18), the plug member (10) (see Fig. 4) is sewn to form a bag-stitched upper (7) (see Fig. 5), and then the rib member (11 ) A middle material (14) such as a viscoelastic material such as sponge or cork and a shank (not shown) are arranged in the space surrounded by (12) Fix the protruding stitches (see Figure 1).

Shoes using the bag-stitched upper of the above structure exhibit the advantages of bag-stitched uppers, such as a good fit and high flexibility, and the outsole (15) is made of fine leather (12
) to prevent water from entering, and the ribs (
Since the insert (14) can be inserted into the space between the outer sole and the outer sole according to 11), the impact absorption property when walking is good. Furthermore, it is also possible to insert a shank material large enough to support the load and maintain the shape of the arch without stepping on it.

<Effects of the Invention> As described above, according to the structure of the shoe sole according to the present invention,
Since the rib member is attached to the lower surface of the inner sole of the bag-stitched upper, it is possible to use the bag-stitched upper to create a shoe that has both the advantages of the Goodyear welt shoemaking method.
