Further, below the insole 2, an insole 2c is provided. For the insole 2c, for example, natural leather, leather board, pulp board, or the like is used. The insole 2 generally has good breathability, moisture absorption and desorption properties, and is preferably excellent in water resistance and sweat resistance. In addition, the insole 2 must be sufficiently tattered while being worn and have sufficient flexibility in the bending portion. It is preferable to use a simple processing that can be shaped to fit the shape of the bottom of the last.

Specifically, at a position corresponding to the sole of the foot,
A coarse porous member 2e is mounted through a through hole 2d having a predetermined shape, so as to improve the contact with the sole of the foot, as well as sweat resistance and air permeability.

Further, the wound leather 3 is mainly made of the same material as the upper 1 and is sewn together with the insole 2 around the edge of the upper 1 (see FIG. 4). In other words, this leather 3
The lower end 3a side is superimposed on the peripheral surface of the upper 1 to protrude from the lower edge of the upper 1, and in such a state, the upper 1 and the insole 2 are sewn at once, and The surplus part projecting downward from the instep 1 is folded as it is on the bottom side of the insole 2c.

The wound leather 3 does not necessarily have to be the same as the material of the upper 1, and different colors or different materials may be used to bring out a change.

An outsole 4 is adhered and fixed to the bottom side of the insole 2c around which the leather 3 is wound, with an insole 5 described later. The outsole 4 is made of a suitable material such as a synthetic resin material, and has a concave portion 4a on the middle bottom surface and guide grooves 4b, 4b,... Communicating with the concave portion 4a, and a separate body in the concave portion 4a. Is detachably disposed.

This shank piece 4c is made of wood, leather, iron,
Rigid material such as plastic or elastic steel spring,
An air hole 4d is made of an elastic material such as rubber or a foamable material, and is vertically penetrated at the center thereof, and air passages 4e, 4e, which are recessed at one end to communicate with the air hole 4d.

In other words, the inside of the shoe (the upper 1) passes from the porous member 2e interposed in the through hole 2d of the inner sole 2c through the guide grooves 4b, 4b. Further, the air reaches the outside air holes 4f, 4f,... Through the air passages 4e, 4e and the air holes 4d of the shank piece 4c, and communicates with the outside air.

A counter 6 made of an appropriate material such as natural leather or synthetic leather is mounted on the heel side of the upper 1 (see FIG. 4). As the natural leather of the counter 6, a tannin-tanned product is used, and there are a single product using tanned leather and a product obtained by laminating several pieces of floor leather. Examples of the synthetic leather include a leather board, a pulp board, and a thermoplastic counter. In addition, 7 in a figure is a suture.

The shoe of the present invention constructed as described above has a structure in which the lower end of the leather 3 is superposed on the peripheral surface of the upper 1 so as to protrude from the lower edge of the upper 1, 3 instep 1
And, since it is sewn together with the insole 2 at the same time, the wound leather 3 does not get rolled up twice and rise up like a bank on the outer periphery of the lower end of the armor 1 as in the prior art. 3E (EEE) or 4E with wide feet without feeling
(EEEE) size people can be handled skillfully.

Since the suture thread 7 of the leather 3 appears as a stitch line from the toe to the side of the instep 1, the stitch down type is apparently a California style shoe. It has novelty and taste, such as the appearance of a wind shoe.

Next, the first step of the shoe manufacturing method according to the present invention will be described. Members such as toe leather, waist leather, back leather and the like cut into a predetermined shape are sewn together to form an upper. As the material of the armor, for example, natural leather, synthetic leather, synthetic resin sheet, cloth, or a composite material thereof is included.

Further, members such as toe leather, upper leather, waist leather, tongue leather, and back leather are cut according to a wooden mold (not shown) or a paper mold, and are trimmed, folded, sewn, and mouth-opened. Sewing around,
It is pierced, eyelet-stitched, tongue-stitched, and knotted.

Next, the second step will be described. First
The armor obtained in the process, the insole and the winding leather are stitched together at once. In this wound leather, the lower end side in the longitudinal direction is superimposed on the peripheral surface of the upper so as to protrude from the lower edge of the upper, and in such a state, the upper and the insole are stitched at once. (See FIG. 4). As such a suturing method, a chain stitch is mainly used, and it is preferable to sew only from the toe to the foot side.

The local stitching of such a portion is not limited to the above-described chain stitch, and it goes without saying that appropriate stitching means such as a lock stitch may be used according to the type of shoes.

Next, the third step will be described. Second
The shoe last and the insole are inserted into the upper made in the process, and the leather is wound as it is or the insole is put on the bottom side. By the way, in the present specification, the middle thing refers to a filling such as sponge, cork or fiber used for filling a concave surface generated during the hanging allowance when an upper is suspended in a last. Say.

Next, the fourth step will be described. Third
The bottom surface side of the insole obtained in the process is subjected to a bonding process such as adhesion or sewing, so that the outsole is brought into close contact, and is removed from the last to complete the final product. As such a bonding process, for example, after the adhesive surface between the upper and the outsole is sufficiently raised and an adhesive is applied, the adhesive is completely dried, and then the adhesive is further adhered with heat. After that, it is preferable to press and adhere the outsole by pressing.

The shoes of the present invention and the method for manufacturing the same are not limited to the present embodiment, but can be freely designed and modified within the scope of the present invention. It is inclusive. For example, as shown in FIGS. 7 and 8, the upper 1, the winding leather 3, and the insole 4 may be sewn at a time, and if necessary, the toe to the foot side and the heel. It may be sutured over the entire circumference of the part.

Next, a first embodiment of a shoe provided with a shank piece according to the present invention will be described with reference to FIGS. To facilitate understanding, the same parts as those in the above-described shoe embodiment are denoted by the same reference numerals, and only the parts having different configurations will be described with new numbers.

FIG. 9 is a perspective view of the insole 2c to which the new shank piece 8 is assembled. The insole 2c is formed from an insole material such as natural leather, a leather board, or a pulp board in which approximately half of the toe side is formed. Almost half from the abdomen to the heel of the foot is made of a highly permeable porous material or a permeable material such as a mesh.

As shown in FIGS. 10 to 12, the shank piece 8 has a plate-shaped piece body 8a and a piece body 8a.
Bulge portion 8b provided on the tip side of
And a cushion portion 8c provided on the rear end side, and ventilation means 9 is formed on the bottom surface.

The piece main body 8a is made of a hard material such as wood, leather, iron, plastic or the like, or an elastic material such as an elastic steel spring, rubber or foamable material. Vent holes 8a ₁ , 8a ₁ ...
When, air passage 8a ₂ which is recessed to communicating vent 8a _1, 8a ₁ ... between each other, 8a ₂ ... and are formed.

The bulging portion 8b is curved so as to bulge upward at least from the surface of the midsole 2c, and has a plurality of ventilation holes 8b ₁ , 8b ₁ .
b ₂ , 8b ₂ ... are formed.

[0045] Furthermore, the cushion portion 8c has a fixed substrate 8c ₁ having a predetermined shape, the elastic member 8c ₂ annular rubber of large and small projecting concentrically on the stationary substrate 8c _1, 8c ₂
, And mainly absorbs the impact force of the foot effectively.
When c ₂ , 8c _2, ... expand and contract, air (inside air and outside air) is forcibly supplied to the ventilation means 9.

[0046] Further, on the bottom surface of the fixed substrate 8c _1, a plurality of inner pores 8c ₃ through the planar recess, 8c ₃ ... and, projecting so as to surround the inner pores 8c _3, 8c ₃ ... Partition wall 8c

Are formed in the outer sole 4 to communicate with the outside.

Therefore, in the shank piece 8 of the present invention thus constructed, the bulging portion 8b stimulates the sole of the foot every time the user walks, and improves the blood circulation by gently pushing up the metatarsal portion. , Can also promote the function of the built-in.

Further, since the cushion portion 8c absorbs the impact force to the foot and is displaced according to the shape and size of the heel, the hitting of the foot against the heel becomes gentle, and the sitting of the heel is also reduced. Because it improves, you will not feel tired even after prolonged use.

Each time the user walks, the cushion portion 8
c automatically operates, so the cushion portion 8c
Depending on the operation of the heat, the heat and odor in the shoes are exhausted to the outside of the shoes, and the outside air is forcibly taken into the shoes, so the heat does not accumulate in the shoes and It can be effectively prevented.

In the shoes of the present invention, when used on a wet road surface such as a rainy or snowy day, if necessary, a device such as a non-slip device is provided on the outsole 4 so as not to slip easily. Needless to say, this is done.

For example, by forming the outsole 4 from a synthetic resin material such as a water-repellent polymer, or by attaching a water-repellent rubber to the bottom surface, water droplets and a water film are quickly removed, and even on a rainy or snowy day. By using a material with anti-slip properties and abrasion resistance and a high coefficient of friction (adhesive friction force), it can withstand long-term walking and fits shoes on roads in adverse conditions. be able to.

Examples of the polymer satisfying the above conditions include a double bond and a five-membered ring formed by ring-opening polymerization of norbornene synthesized from ethylene and cyclopentadiene (by a Diels-Alder reaction). It is preferable to use polynorbornene having a structure in which are bonded alternately.

Since the polynorbornene is a low rebound resilience rubber having a large vibration absorbing power, it is mounted on the outsole 4 to detect high rebound resilience and low rebound resilience depending on the road surface conditions and the like. This is because, in order to cope with the problem, an advantage of preventing fatigue and pain of the foot can be obtained.

Further, unlike conventional sponge rubber, it has a property of not absorbing water, and has a low hardness and a high strength as compared with other rubber materials, so that the wear rate is extremely low.
In addition, it is sensitive to changes in hardness with temperature, changes in climate,
Because it can quickly detect temperature conditions, cope with walking conditions in sunny, rainy and snowy conditions, and provide the outsole 4 that satisfies all conditions of shoes, such as the ability to firmly grip the road surface and floor surface. is there.

As described above, according to the present invention, the use of such a polymer for the outsole 4 has an effect of removing a water film on a wet road surface due to high water repellency, and has a high abrasion resistance and a high coefficient of friction (adhesive friction). Force), it can withstand walking for a long time, and has both high resilience and low resilience to cope with road conditions, preventing foot fatigue and pain, low hardness and high strength Therefore, the wear rate is extremely low, and it is possible to freely control a warm sensation region such as a change in climate or a temperature condition.

Next, the second shank piece according to the present invention will be described.
