Description

[Detailed description of the invention] [Industrial technical field] The present invention uses a concave insole made of an elastic material with a convex portion formed on the periphery, and a shell with a shell or a battledore with a shell on the flat concave surface. This relates to a method of manufacturing slippers in which the sole is iron-inserted, the outsole is placed on the back side of the midsole, and all of these are twilled at the peripheral edge.

[Following technology] Slippers that are currently in general use can be roughly divided into two types: products using the hook-in method as shown in Figures 1 and 2, and products using the outside stitching method as shown in Figures 4 and 5.
It is a kind.

In the former case, when manufacturing the upper part 1 of the slipper, a fishing machine is used to hook the deck 3 onto the lower peripheral edge of the middle plate 2, which is called a ghost, as shown in Fig. 3. The structure is such that a middle plate 1 with an instep is made, a heel part 4 and an outsole 5 are overlapped and sewn to this, and an insole 8 is attached to the upper surface.
On the other hand, the latter outside sewing method involves bending the peripheral green part of the deck 3 outward without using the fishing machine, and extending the new curved edge 3' to the upper peripheral green part of the slipper sole 2' as shown in FIG. It has a structure in which the fabric is layered on top of the fabric, a hemline 6 is applied thereto, and the fabric is sewn together using a sewing machine 7. The latter method of outside stitching creates a border 3' around the periphery of the upper of the slipper, which may be because it acts as a kind of decorative border, and has become a popular product as it matches consumer tastes. There is.

However, as is clear from Figure 5, the tip of this shoe has a triangular cross-section, so when the slipper is covered, the tip of the foot does not fit all the way to the tip of the slipper, and it tends to fall off. Ta. On the other hand, according to the hook-in method shown in FIGS. 1 and 2, since the cross-sectional shape of the toe portion is oval, there is an advantage that the above-mentioned foot insertion effect is excellent and the shoe is comfortable to wear. In addition, Jitsuneki Publication No. 53-513y discloses a method for manufacturing slippers, sandals, and other coverings using a footwear stand with a concave cross section; Furthermore, the upper is attached to the insole or footwear stand, and it is not a so-called fishing method.
It lacks flexibility, which is essential for slippers, and is not suitable for mass production due to the bonding method.Furthermore, a separate footwear stand must be prepared each time the specifications of the tane part and insole are changed. It's inconvenient.

[Purpose of the invention]

Here, the present invention maintains the appearance of the product created by the above-mentioned outside stitching method, and also has flexibility and flexibility by using the hook-in method, and has good foot-insertion action. The aim was to obtain a robust product that would not lose its shape or lose its shape.

Furthermore, in order to improve workability during manufacturing, the present invention adopts a concave insole with a flat concave surface at the center and a convex surface at the periphery as the base of the slipper. By making it possible to freely set the height of the seed part and to replace the insole without changing the specifications of the insole, which is the base, we aim to mass-produce a wide variety of products. It is something that [Example] Figures 6 to 8 are conceptual diagrams showing the method of manufacturing slippers of the present invention, in which reference numeral 11 is a main sole, 12 is a sole having a convex part 13 on the periphery, and a flat central part. This is a fan-flat midsole with a concave overall cross section as a recessed surface 14.

Therefore, this concave insole is made of a material with elastic hem, such as sponge foam or rubber, and in front of the upper surface of this concave surface, a midsole with a shell manufactured by the fishing method as described below is installed. At the same time as ironing, a heel part is interposed on the lower surface of the insole as necessary, and the outsole is stacked on top of each other, and then these are sewn together by a machine.

Next, the insole is inserted into the insole with the instep, and the insole of the braces is also completely fitted into the recessed surface 3 of the concave insole and attached to the insole integrally. In addition, code 15
16 is an insole, 16 is a heel, 17 is a deck hooked into a middle plate 18 made of a ghost or a battledore, etc., and 19 is a sewing thread using an Happo sewing machine or a flat bed sewing machine. The three-sole sole 11 may be made of any material such as leather, foamed plastic, synthetic rubber, or felt, and if necessary, an outer skin material 11a such as vinyl leather may be attached from the bottom to the periphery as shown in FIG. good. Note that when the outsole 11 is made of felt sole 4, there is no need to attach an outer skin material. The insole 15, heel 16, etc. other than the concave insole 12 are also included in the outsole 1.
It can be made from the same material as 1, but it is possible to make it from a material with high cushioning properties such as sponge. As mentioned above, the concave inner sole 12 is made of foamed plastic,
The requirement is that it be made of a material with elasticity such as synthetic rubber, and that a protrusion 13 is formed on the periphery, and a flat concave surface 14 is formed in the center. Although it is preferable that the concave surface is integrally molded, the convex portion 13 may be added later by pasting a molded strip with a rectangular cross section around the flat portion.
As shown in FIGS. 9 and 10, the heel 16 is covered with green wrapping 12a or 16a using cloth, vinyl leather, or the like. Depending on the case, the insole 15 may have a sponge cushioning material 10 inserted into that part.
The outer material 5a, such as cloth or vinyl leather, can be worn from the upper surface of the insole including 0 to the surrounding green.
To manufacture slippers by this method, first, the deck mass 7 is hooked into a middle plate 18, such as a ghost or battledore made of non-woven fabric, using a fishing machine.

Since the deck 17 is attached to the middle plate 181 by a fishing machine, the toe portion thereof is bulged in a relatively large oval shape, and then
The lower side 17a is adhesively fixed to the lower surface of the middle plate 18. Therefore, a depth with height is formed at the tip of the toe in Koto. On the other hand, after temporarily attaching a heel 16 having a rectangular cross section to the seed part of the outsole 11 if necessary, the concave insole 12 is placed thereon, and on the other hand, the upper surface of this concave insole 12, that is, the convex ratio part 13 In the first half of the flat depressed surface 14 surrounded by
Insert the middle plate 18 into which the deck 17, which is the upper part, is attached, and attach it to the inner sole if necessary, and then attach the upper part, the inner sole, and the original (including the heel if there is a heel). Sew the three parts together using the sewing machine 19. In this way, the deck 17
is a flat depressed surface 1 surrounded by a convex part 13 of a concave inner sole 12
4, so the protrusion around the deck 13
As a result, a buffer body is provided around the slipper with a predetermined width from the toe to both sides, like a protective wall.By the way, the sewing thread 19 is used as shown in Figure 10. It is inserted along the inside of the convex part 13, including the fishing part of the deck 17, thereby integrating the upper part with the outsole 11 and the concave insole 12. , insert the insole 16 into the deck 17 and
Paste this to obtain the finished slipper product. By the way,
When the concave insole 12, heel 16, etc. in the embodiment described above are covered with green wrappings 12a, 16a of kohl or other fabric, the entire slipper has a warm appearance and has a good feel.

Furthermore, when the outsole 11, concave insole 12, insole 15, heel 16, etc. are all made of foamed plastic sheets or synthetic rubber sheets such as EVA, urethane, and styrene, they are water resistant and durable. It can also be made to have excellent washability. [Effects] ■ Since the present invention has the above-mentioned configuration, it is possible to manufacture slippers having a type of buffer wall in which the convex part of the concave insole protrudes in an inorganic manner on the outside of the instep. Even if the toe of the slipper gets caught on a threshold or the like, the protrusion cushions the shock, making the slipper strong.

■ To manufacture slippers that look as if they were manufactured using the outside sewing method, and that, unlike the conventional outside sewing method, the instep is recessed so that the slippers fit easily and are comfortable to wear. I can do it.

■ Also, according to the present invention, when positioning the upper part, which is the most important part in adjusting the appearance of the slippers, by iron-fitting the upper part into the front half of the upper surface of the concave inner sole, the predetermined position can be set simply by iron-fitting the upper part. Once it is decided, the sewing process is easy as all you have to do is to sew it with a sewing machine along the inside of the convex part of the concave insole, and the upper part is already hooked into the midsole, so it is easy to sew the shape of the upper. This prevents the product from collapsing, making it possible to mass-produce products with consistent quality.

■Furthermore, since the present invention is characterized by the use of a concave insole made of a material with rock-like properties, it is possible to manufacture products that are easy to handle, have a good texture, and do not easily fall off when walking. Since the concave insole has a flat concave surface in the center, it is possible to sew not only the front half but also the seed part in the latter half, and if necessary, the heel 16 can be inserted between the insole and the main sole. Since the height of the seed part can be adjusted in such a manner that the height of the seed part can be adjusted, a variety of products with different heights of the seed part can be manufactured using the same member.

■According to the present invention, the upper part, the concave midsole, and the outsole are superimposed and all of them are sewn together by a sewing machine over the entire circumferential area, making it possible to make a sturdy product. The insole is fixed by fitting it into the inside of the protruding part of the periphery of the insole, so there is no misalignment, and only this area can be integrated in the courtyard, outsole, and instep. It also has the effect of being able to be replaced regardless of the part.
