Description

[Detailed description of the invention] The present invention relates to a shoe and a method for manufacturing the same.

The purpose is to form the base of shoes from the smallest piece of material, to easily and quickly produce shoes that are comfortable to wear and highly durable, and to provide a preferable manufacturing method. be.

Shoes are indispensable equipment for humankind's outdoor activities today, and research and development has been carried out since ancient times to manufacture these shoes. Therefore, in order to obtain shoes, it is considered that there is no choice but to use a sole member as a base and attach a plurality of covering members for the instep or heel to the upper circumferential side of the sole member. There is. In other words, when using such a method, even if the desired shape can be formed depending on the covering member, since a plurality of unit materials are required to form the basic body, it is difficult to manufacture it. many 1
In particular, the sewing process is very time-consuming, and the number of necessary parts must also increase due to the need for auxiliary materials, which inevitably leads to an increase in cost. Moreover, its strength is mainly due to, as mentioned above,
Since it depends on the sewn joint between the base member and the covering member, it is obvious that special care must be taken with regard to the seam joint of this part, and even if this is done, it will not be sufficient. It is not easy to obtain sufficient strength and durability.In addition, its shape W, % fA, and composition do not necessarily suit the feet of users.

For this reason, it has disadvantages such as not necessarily being comfortable to wear.

The present invention was developed after repeated consideration in view of the above-mentioned circumstances, and it is clear that the minimum necessary
The purpose is to form the base of this polar axis with a piece of material, thereby minimizing the number of seams or joints in the base, thereby making it possible to easily and quickly obtain the desired shoe. Furthermore, they succeeded in providing shoes that were comfortable to wear.

That is, the specific manufacturing process and structure of the product according to the present invention will be explained with reference to the attached drawings.'In the present invention, a piece of material 1 as shown in FIG. The material piece 1 has a toe-corresponding part 11 and a heel-corresponding part 1 in the front and back.
2, and between these parts 11 and 12, side pieces 13 and 1 are to cover the instep part or the foot lock part in series on the masterpiece side.
3 are integrally formed, and the end edges of these side pieces 13, 13 have a first joint II & 14 to be joined on the instep, a opening rim 15 of the opening to form the first joint, and a rear surface of the heel. The second joining edge 16 that should be joined laterally is the part corresponding to the toe 1.
1 to the heel equivalent portion 12. Incidentally, such a side piece 13.13 is formed with a notch step IT projecting moderately between the first joining edge 14 and the toe corresponding part 11, and the notch step 1T is connected to the toe corresponding part 11.゛Department-,
By joining to the edge of t-S-, a swell a sufficient to accommodate the toe part is formed, and each heel corresponding part 12 and the second joining edge 16 are glued together. Another cut step 18 is similarly formed to protrude, and by joining the cut step 18 to the edge of the heel equivalent portion 12, the heel or heel portion 18 is formed behind the heel portion 12 as shown in FIG. After foot failure rI
An rJ accommodating portion is formed.

Each of the joints #14 and 1B as described above are joined, and the cut step portions 1γ and 18 are connected to the toe equivalent portion 11 and the heel equivalent portion 1.
The state in which it is joined to the edge of 2 is as shown in Fig. 2,
The joint may be formed by four-way stitching or by gluing, but either way the shoe base 10 as shown in FIG. 2 is automatically obtained. Regarding these mating points, it is clear that the joints are all linear, and it is also clear from the illustrations that they are relatively short and small, and furthermore, it is clear that the joints are straight butt joints. It can be easily understood at a glance from the illustration that the bonding can be done very easily and quickly regardless of the force used. It should be noted that the joints formed in this way are coated with @ adhesive tape 3 as appropriate.
A stable bonding strength can be obtained by adhering the adhesive tape 3 to the outside. In other words, even a relatively thin layer of adhesive tape 3 with a release material 3a attached can provide a preferable adhesive strength, especially at the joint part. Effective strength against tension in the corner direction can be ensured. This adhesive tape 3 may be of a general type, but it is clear that it is preferable to use a waterproof and moisture-permeable adhesive as will be explained next with respect to the material piece 11. Since the parts are aligned and joined in a straight line, they can be easily and stably bonded.

As for the above-mentioned material piece 1, use fllf: what you want! Ordinary leather or woven fabric with appropriate strength.
It is obvious that any cloth will do.

Of course, it is preferable to use waterproof and breathable materials.
Examples of such waterproof and moisture permeable fabrics include laminate fabrics of non-hydrophilic porous films, such as stretched porous ethylene tetrafluoride resin films developed by the present applicant. That is, a preferred example of such a material piece 11 as a laminated fabric of such a non-hydrophilic porous film is as shown in FIG.
A is laminated with a sponge-like cushion layer 1c and a protective cloth 1d bonded to the inside of the laminated material, and has appropriate flexibility and moldability as a shoe, and is waterproof. A product with guaranteed moisture permeability can be obtained. However, even if Akira Motomoto's work uses laminate or synthetic materials like Kozukiko's, its f.
li:! It is the above-mentioned advantage that the above seven materials can be appropriately adopted, and the above-mentioned waterproof and moisture-permeable fabric can also be coated with a non-hydrophilic porous layer (for example, non-hydrophilic polyacrylic resin, etc.). coating materials), laminate fabrics with water vapor permeable non-porous films (e.g. laminates with films coated with hydrophilic raw polyurethane resins or hydrophilic fluorine tree fertilizers), coated fabrics with water vapor permeable non-porous R layers (e.g. Porous Layer Coating Material Made of Hydrophilic Polyurethane or Hydrophilic Fluorine Tree Fertilizer) When the desired high-density 1-fiber fabric is selected, one of these materials can be selected and adopted as appropriate.

For the base body 10 obtained as shown in the above CC, in order to ensure the durability of the outer layer, final cut, and other necessary parts of the shoe, an outer cover body 2 and a fifth cover body as shown in FIG. 4 are attached. A bottom member 4 as shown in the figure is attached. In other words, it is possible to use any arbitrary material as the outer sheath body 2 and the bottom member 4. As the bottom member 4, a wide variety of common commercially available products are used. Available.

The base body 10 has already been obtained as the outer cover body 2, and since it is adhesively attached to the surface of this body to obtain an external appearance, a simple one is sufficient. .

A cross-sectional view of one example of the completed shoe is shown in FIG. 6, and is obtained with appropriate appearance, strength, and durability. An example of a cross-sectional structure in which the jacket body 2 is adhered to the surface of the base body 10 as described above is shown in FIG.

The outer cover body 2 can be formed into a stable structure using a laminate material of an inner material 21 and an outer material 22.

The embodiments described above are used as short shoes, but
It is clear that the same effect can be obtained even in half-boots or rain boots by extending the opening edge 15 of groove 1 in the piece of material 1 shown in Fig. 1. In these cases, the first joining edge 1-4,
14 and the joining length between the second mating edges 16 and 16 are slightly improved, and there is no substantial difference in ease from what has been described above.

Also, as the bottom member 4, spikes or something similar +9
It is clear that by using the self-produced ones, running shoes can be obtained as special floppy shoes for various ball games, and in some cases, high heels with a high heel can also be used.

According to the present invention as described above, this polar axis can be easily and quickly obtained by employing a piece of material having the structure typically shown in FIG. It is clear that the base 10 can be obtained with a minimum number of single material pieces, the length of the joint is small, and the joint is a -P surface edge joint, so sewing or polymerization is not necessary. Whichever method you choose, it is simple and accurate, and can ensure sufficient strength. Trouble due to
Therefore, it is possible to obtain the desired shoes quickly and at low cost, and in addition, there are almost no scratches such as the I-wear joint on the sole of the wearer's foot or its surroundings. Because it is not used, it is comfortable to wear regardless of whether you are walking or running, and it has the advantage of being comfortable to use.Furthermore, the amount of cut-off waste that can be produced by molding and collecting multiple pieces of material from the base material is low. Industrial ζ is an invention with great effects.
