Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an insole for a shoe that makes it possible to manufacture a product having an auxiliary fA structure in cloth shoes and leather shoes using a hanging method, and the insole for the shoe. The present invention relates to a manufacturing method.

[Conventional technology]

Conventionally, this type of device is as follows.

1. When wearing shoes, most people suffer from leaky feet due to sweating, and many suffer from injuries and illnesses such as athlete's foot.

As a way to relieve this pain, some people put moisture-proof insoles inside their shoes, but this reduces the width of the shoes and makes the feet feel tight and uncomfortable. , toes may become deformed.

Wearing shoes that don't fit your feet can also cause other health problems.

Therefore, when considering how to wear shoes under normal conditions, it is desirable that the moisture-proofing effect be incorporated into the shoe manufacturing process and commercialized.

2. For a highly moisture-proof insole, the material is a non-water-absorbing synthetic resin with a diameter of 0.5 mm to 2 mm, and LIL fiber is good.
The structure should preferably be a rope-like structure with many spaces.

In addition, in order to further enhance the moisture-proofing effect, it is preferable to laminate several layers of this net-like knitted fabric to a thickness of 2 mm to 5 mm so that the entire insole forms an air layer.

However, this insole is structurally easily deformed by external forces such as tension and compression, and is difficult to mold in the shoe manufacturing process, so it has hardly ever been commercialized.

3. Generally speaking, in cloth shoes or leather shoes where the lace material is hung and attached or nailed to the midsole, the midsole is hard and matches the shape of the bottom of the shoe last, and can be pulled from front to back and from side to side. An important condition in the manufacturing process is that it does not deform even when it is compressed or compressed.

In other words, human feet are rounded and swollen. It is a series of depressions or depression curves.

Therefore, the same goes for shoe lasts; in the hanging-type molding process for cloth shoes and leather shoes, the material of the shoe's heel is strongly stretched along the curve of the shoe last, and is glued or nailed to the insole. Hit and fix.

At this time, if the lace material that has been stretched on the insole stretches or shrinks against the force of trying to return to its original shape, it will not be able to maintain the shape of the shoe last, making it extremely difficult to mold the shoe. .

[Problem B to be Solved by the Invention] The conventional techniques described above had the following problems.

1. In particular, in the case of an insole with a net-like structure that has a high moisture-proofing effect, the insole deforms significantly depending on the amount of force applied, and the heel, toe, and tread may be on the inside of the part, on the outside of the part, or on the inside of the part that is not stepped on, or on the outside of the same part. Even if the material of the splint is fixed by suspending adhesive or nailing while dispersing the tensile force, the workability is poor and the normal midsole surface cannot be maintained.

In particular, when hanging by a machine, the inner sole of the net-like structure bulges toward the center and cannot be formed because it is hung from the front, back, left, and right toward the center at the same time.

2. As described above, it is a necessary condition in the molding process that the insole is hard and does not deform even if some force is applied.

The present invention has been devised in view of the above-mentioned problems of the prior art, and its purpose is to provide a device that can do the following.

In order to make shoes using a net-like inner sole that has a high moisture-proofing effect, it is necessary to improve the net-like inner sole so that it does not deform when suspended, and it must not stretch even when it is pulled. .

For this reason, first, the net-like midsole is combined and integrated with a hard material that can withstand tension, thereby making the net-like midsole non-stretchable.

Next, when hanging, the heel part of the insole is made of hard and thick material such as moon-shaped material or shank material, and since there is air convection while walking and there is relatively little humidity, the heel part of the insole is moisture-proof. It should be made of a hard material that can withstand the force of lifting when removed from the structure.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

The midsole in the shoe of the first invention is constructed as follows.

The inner sole of the net-like structure is combined with a hard material to make the inner sole of the rope-like structure non-stretchable, and the heel part of the inner sole is made of a hard material that can withstand the force of lifting when removed from the moisture-proof structure. It is configured as.

In addition, when the net-like structure part and the concave part are combined, an air layer with a width of 3 mm to 7 cm is formed in the rice insole. Shoes with this moisture-proof inner sole have extremely high cold-proofing effects (they have a moisture-proof and cold-proof structure).

In addition, water droplets with a diameter of lam are formed in the form of particles in the recesses provided in the sheet, but each recess is formed independently, which prevents the water droplets from flowing and gathering in one place to wet the soles of the feet. It has the effect of preventing

Also, the water droplets can evaporate at room temperature by the next morning after taking the drug.

A heel portion 4 made of a hard sheet is obtained.

Next, apply rubber glue to the slotted part 4A (see Figure 7).
.

The sheet refers to foamed rubber, foamed synthetic resin, or compressed board impregnated with synthetic resin or glue that does not deform or deteriorate during vulcanization.

Fifth step: The non-water-absorbing semi-hard sheet is pressed on in part 2, the unvulcanized rubber sheet is pressed on in part 3, the heel part 4 of the non-water-absorbent hard sheet is placed on the mold body 6 for creating a moisture-proof inner sole, Set the heel part 4 of the non-water-absorbent hard sheet, the part 2 for the non-water-absorbent semi-rigid sheet, and the part 3 for the unvulcanized rubber sheet (see Figure 13), and create a moisture-proof inner sole. The upper lid 5 of the creation mold is closed, and vulcanization is performed by applying pressure and heating with a vulcanizing press.

On the upper lid 5 of the mold for creating an inner sole with a moisture-proof structure, an unvulcanized rubber sheet is pressed on the upper surface of the part 3 to a depth of 1.5 sm to 2111 m.
, a rectangular recess with a length of 2 m 11 to 311 @ and a width of 10 mm to 20 mm, a depth of 1.5 mm to 2 mm, and a diameter of 3 mm.
It is engraved and designed so that a large number of circular recesses 5A of ~5cm are formed.

After the 6th step vulcanization time has elapsed, the mold for producing a moisture-proof inner sole is taken out from the vulcanizing press, the upper mold lid 5 is opened, and the semi-finished product 7 of the moisture-proof inner sole is taken out.

The non-water-absorbing semi-rigid sheet is stepped on in part 2, the unvulcanized rubber sheet is stepped on in part 3, the non-water-absorbent hard sheet is stepped on in part 4, and the rubber glue and unvulcanized rubber sheet are stepped on in part 2. 3, and a number of recesses 3A are formed on the upper surface of the tread portion 3 by the molded upper cover 5 (see FIG. 14).

Seventh step: Next, the non-water absorbent network structure knitted fabric tread section 1 is stacked and fixed on top of the semi-finished product 7 of the moisture-proof structure insole (above the concave shape) so as not to shift from front to back and from side to side.

Fixing methods include: ■ Dotting in several places with adhesive;
There are two methods: ■Sewing method in which the center and periphery are sewn using a sewing machine, and ■Punching method in which the material is stopped by caulking, etc., but the choice should be made in consideration of preference, workability, cost, etc.

With the above steps, the moisture-proof structure insole A according to manufacturing method 1 is completed.

Manufacturing method 2 First step: Hard thermoplastic vinyl chloride is rolled at a temperature of 80° C. to 120° C. using a rolling press plate with a design or a roll dispensing machine, and then cooled.

As a result, a semi-finished product 8 shown in FIG. 17 is obtained.

The press plate is engraved with the same thickness and the same design as the semi-finished product 8 of the moisture-proof inner sole created in the 6th step of manufacturing method 1 on the vinyl chloride sheet. Both have a long length (sheet width) of about 35 cm.

Also, in the case of roll dispensing, the rolls are engraved so that sheets similar to those described above are dispensed.

In the case of press plates, workability is good if the length (vertical) of each sheet is 051 to Im (see Figure 17), but in the case of roll dispensing, 2 m to 3 ffi will result in less loss and better retention. expensive.

The second step is the same as the first step of manufacturing method 1, and the meltable network structure knitted fabric 8A is layered on the vinyl chloride-based 1a layer.
(See Figure 19).

In this case, in the third step, which may be laminated to any desired thickness, a cutting die for the insole is attached to a 1m high-frequency heat fusion welder, and the vinyl chloride sheets stacked in the second step of manufacturing method 2 and the rope are laminated.

By placing several short metal rods with a diameter of 21 to 3 mm and made of the same material as the insole cutting die inside the insole cutting die, the surrounding area is cut by heat melting, and several parts of the treading part are heat fused. (see Fig. 21 and Fig. 20).

In the figure, reference numeral 8B indicates a groove-shaped portion carved with a metal rod.

After cutting out in the 4th step, the moisture-proof 4.1 was cut into a midsole shape using a high-frequency Kuhe fusion machine! Remove the midsole.

The Kosho A heat fusion machine has functions such as fusion, melt cutting, etc. by adjusting the current, time, and pressure, as well as the shape of the presser die.

With the above steps, the moisture-proof structure inner sole B according to manufacturing method 2 is completed.

Manufacturing method 3 First step: Put an appropriate amount of hard unvulcanized rubber (mixed with vulcanizing agent) into the mold body 6 to create the M structure inner sole, which is used in the fifth step of manufacturing method 1. Vulcanize.

After the second step of vulcanization, open the upper mold lid 5 and remove the semi-finished product 9 with a moisture-proof inner sole.
(See Figure 22).

The shape of the semi-finished product 9 of the moisture-proof insole is the same as that created in the sixth step of manufacturing method 1, but the material is one piece made of hard vulcanized rubber.

Third step Next, on top of the semi-finished product 9 of the moisture-proof inner sole (above the concave shape), the non-water-absorbing network structure knitted fabric part 1 is stacked and fixed so that it does not shift from front to back and from side to side. (See Figure 24).

Fixing methods include: ■ Dotting in several places with adhesive;
■There is a sewing method that uses a sewing machine to sew around the center and the periphery, ■a punching sewing machine that uses crimping, etc., but depending on your preference,
The selection may be made in consideration of workability, cost, etc.

With the above steps, the moisture-proof structure inner sole C is completed.

From then on, cloth shoes and leather shoes will be manufactured using normal shoemaking methods.

In manufacturing method 1.3, a moisture-proof insole is created by fixing a knitted fabric in the shape of a tread to an integral part (semi-finished product) of a heel and a tread in the shape of the insole.

In manufacturing method 2, the shape of the insole is obtained for the first time in the fourth step, and until then, the vinyl chloride sheet and the knitted fabric are just materials.

In manufacturing method 1.3, the insole is made one pair at a time, but in manufacturing method 2, it is in the form of a large sheet until it is punched out with a cutting die (electrothermal).

In addition, in manufacturing method 2, the vinyl and knitted fabric are punched out and simultaneously fixed (become one) to form the inner sole.

Referring to FIG. 18, 10 is a shoe manufactured using the moisture-proof inner sole obtained by manufacturing method 1.

In the figure, IOA is the core sole, IOB is the outer sole, tOC is the toe reinforcing material, 100 is the moon-shaped material, and IOE is the lace material.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

When manufacturing cloth shoes or leather shoes using normal shoemaking methods,
This moisture-proof structure insole does not deform even if it is strongly pulled by the lace material during hanging, and can be molded easily and accurately. Now it is possible to create products with a moisture-proof structure in the inner sole.

The moisture-proof structure insole obtained according to the present invention is made of non-water-absorbing synthetic fibers from the non-stepping part to the toe part, and is constructed by knitting single fibers of a predetermined diameter into a rope-like structure and having a predetermined thickness.

For this reason, the moisture sweated during employment does not accumulate on the soles of the feet, but passes through the socks and the net-like structure, reaching the rubber sheet (vinyl chloride sheet in manufacturing method 2) underneath, and reaching the top surface of the sheet. Water drops of a predetermined diameter accumulate in the rectangular or circular recesses that make up the structure, and the soles of the feet are maintained in a dry state with extremely low humidity, eliminating the feeling of stuffiness.

In addition, when the net-like structure part and the recessed part are combined, an air layer of a predetermined width is formed in the rice insole.This air layer not only increases the moisture-proofing effect of the sole of the foot, but also has a high insulation effect. Shoes with moisture-proof inner soles can also have extremely high cold-proofing effects (they have a moisture-proof and cold-proof structure).

In addition, water droplets of a predetermined diameter form in the recesses provided in the sheet, but each recess is formed independently, which has the effect of preventing the water droplets from flowing and gathering in one place and wetting the soles of the feet. There is.

In addition, these water droplets can evaporate at room temperature by the next morning after wearing.
