BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe and a method for manufacturing the shoe, which can be adjusted to fit the foot, particularly in terms of width.

[0002]

2. Description of the Related Art Conventionally, custom-made shoes have been used as a means for obtaining shoes that are suitable for the feet. this is,
The length of each part of the foot is measured, the foot is placed on a piece of paper, a pencil is put around the foot, the shape is recorded, a shoe mold is formed in accordance with this, and a shoe is manufactured using this shoe mold.

This made-to-order product, after receiving an order,
Since the shoe mold and shoes are manufactured from the beginning, it takes time and trouble. Moreover, since this method measures and records the outer shape of the foot, it cannot cope with changes in the swelling state with time, differences in the thickness of subcutaneous fat, or individual differences in preference for the tightening force of shoes, so it is not always accurate. I can't get shoes that fit my feet.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention has been devised for the purpose of obtaining a shoe that is more similar to a ready-made shoe and more suitable to the foot, and is as easy as the existing shoe. is there.

[0005]

The present invention is a shoe characterized in that the front portion of the shoe sole is formed so as to be capable of expanding and contracting in the width direction.

The present invention also includes a shoe characterized in that a front end of the shoe sole is formed with a slit extending in the front-rear direction so that the shoe can expand and contract in the width direction.

According to the manufacturing method of the present invention, the front portion of the shoe sole is formed to be expandable and contractible in the width direction to form a semi-finished shoe, and thereafter, a shoe mold having an appropriate width is selected inside the semi-finished shoe. It is a method of manufacturing a shoe in which the shoe is completed by putting it in, adhering the surface portion of the outsole, and making the front portion of the shoe sole incompatible.

According to another method of the present invention, the front part of the shoe sole is formed to be stretchable in the width direction to give a semi-finished shoe, and then this semi-finished shoe is put on the user's foot, Measure and record the outer shape of the semi-finished shoe, and then put the shoe mold corresponding to the measurement record inside the semi-finished shoe or other semi-finished shoe similar to the semi-finished article, and bond the outer surface of the outsole. This is a shoe manufacturing method that completes a shoe by making the front part of the shoe sole inelastic.

Yet another method of manufacturing the present invention is to use a shoe sole whose front portion is separated and replaceable, and which is attached with a shoe sole front portion formed to be stretchable in the width direction. The shoe semi-finished product is put on the user's foot to measure and record the outer shape of the shoe semi-finished product, and then the shoe mold corresponding to the measurement record is placed inside the shoe semi-finished product. It is a method of manufacturing a shoe in which the shoe is completed by inserting the shoe, replacing the front portion of the book sole with another front portion of the book sole that is not stretchable, and fixing the same.

Embodiments of the present invention will be specifically described below with reference to the drawings.

1 and 2 show a shoe 10 of the present invention. The shoe 10 is a high heel shoe for women. Slits 13, 13 extending in the front-rear direction are formed in the front part of the outsole 12 forming the shoe sole 11 of the shoe 10. This outsole 12
Inside, an inside material 14 and an insole 15 are provided. Both slits 13 and 13 are located between the lower end of the upper 16 and the midsole 14, and the midsole 15 is formed of a stretchable material such as thin leather or cloth. Therefore, the sole 11
The front part of can be expanded and contracted in the width direction. In the figure,
17 is the heel.

Since the shoe 10 has the above-mentioned structure, when it is worn on the foot, the slits 13, 13 are opened in conformity with the foot, and the width of the front part of the shoe sole 11 is extended, so that a comfortable wearing feeling can be obtained.
Since the slits 13, 13 have a shape extending in the front-rear direction, the shoe sole 11 does not extend in the front-rear direction.
In particular, since the shoe 10 uses the slits 13 and 13, the force for tightening the foot is small and the shoe 10 has a soft feel. It should be noted that if the slit is made deeper to reach the insole, it becomes even softer. This shoe 10 is suitable for indoor use because the waterproof property is lowered by the slits 13, 13.

3 and 4 show another shoe 20 of the present invention.
The shoe 20 is a high heel shoe for women. This shoe 20
A long hole 23 extending in the front-rear direction is formed in the front portion of the outsole 22 forming the shoe sole 21, and a rubber sheet 24 is bonded thereto. Inside the book bottom 22, a midsole 25 and a midsole 26 are provided. The midsole 25 is made of foamed rubber or the like, and the midsole 26 is made of thin leather, cloth or the like, both of which have elasticity. Therefore, the front part of the shoe sole 21 can be expanded and contracted in the width direction. In the figure, 27 is upper, 28
Is the heel.

Since the shoe 20 has the above-mentioned structure, when it is worn on the foot, the rubber sheet 24 stretches in accordance with the foot and the long hole 2
3 is opened and the width of the front part of the sole 11 is extended to provide a comfortable fit. In particular, since the shoe 20 uses the rubber sheet 24, the force for tightening the foot can be adjusted by selecting the hardness of the rubber sheet 24, and the foot can be tightened more strongly. Become.

In each of the above examples, the slit and the long hole with the rubber sheet are used. However, the shoe of the present invention may be made of cloth, mesh or the like, and the width of the shoe sole can be expanded and contracted. If it is possible, any structure and material can be used.

Next, regarding the first method of manufacturing the shoe of the present invention,
This will be described in detail with reference to FIGS.

In this manufacturing method, the shoe 10 of the above example is used as it is as a semi-finished shoe 30. That is, the slits 33, 33 are formed in the front part of the outsole 32 forming the shoe sole 31, so that the front part of the shoe sole 31 can expand and contract in the width direction. In the figure, 34 is a medium item, 3
5 is an insole, 36 is an upper, and 37 is a heel. Usually, these semi-finished products are stored in retail stores, wholesalers or factories.

When an order for shoes is received, a shoe mold 38 having a width according to the order is selected from the shoe molds prepared in advance, and the shoe mold 38 is placed inside the semi-finished product 30 of shoes and the surface of the outsole. The part 39 is adhered to complete the shoe 40. As the outsole surface portion 39 used here, ones having various widths are prepared in accordance with the width of the shoe, and are selectively used, or a large portion is adhered, and an unnecessary protruding portion is removed later. However, since the difference between the maximum and minimum widths of the finished shoe is usually about several millimeters, usually 5 millimeters or less, it is sufficient to prepare one type and simply bond these.

The shoe 40 thus formed has a width according to the order, and the front portion of the shoe sole is not expandable or contractable, like a normal shoe. This bonding work is extremely easy and can be done in a short time of a few minutes, so not only in the factory but also in retail stores,
It can also be implemented at a wholesaler.

In this manufacturing method, since the shoe sole has a double layer of the outsole 32 and the surface portion 39 of the outsole, it is desirable that the thickness of the outsole 32 is thinner than that in the above example. Semi-finished shoes
The shoe of the above example may have any configuration, but the configuration having slits is simple and practically suitable.

Next, the second method of manufacturing the shoe of the present invention will be described in detail. In this manufacturing method, the shoe mold of the above manufacturing method is fitted to the foot of the customer.

In this manufacturing method, the above-described shoe of the present invention, which has the front part of the shoe sole capable of expanding and contracting, is directly used as a semi-finished product. This specific configuration is arbitrary such as one using a slit or one using a long hole with a rubber sheet. Usually, this semi-finished product is stored in a retail store.

When the customer selects a desired semi-finished shoe, the semi-finished shoe is put on the customer's foot, and the outer shape of the semi-finished shoe is measured and recorded. This measurement recording method is arbitrary as long as it can record the outer shape of the semi-finished shoes, and for example, the following method can be used. (1) Measure the width of a specific position on the bottom of the shoe and record the value. (2) Measure the circumference of a specific position on the instep and record the value. (3) Place on a piece of paper and put a pencil around the front part of the shoe sole to wrap it around and record the shape. (4) Apply a stamp to the front of the shoe sole to apply ink, and copy the shape onto paper. (5) Place on clay and record the shape of the sole by the depression.

Next, a shoe last is prepared and placed inside the semi-finished product of the shoe so as to match the measurement record. The method of preparing the shoe last is arbitrary, but the following method can be used, for example. (1) Prepare shoe molds corresponding to various widths in advance, and select an appropriate one from them. Usually several, at most one
It suffices to prepare 0 or less widths. (2) A piece of leather, plastic or the like having a suitable thickness is attached to both side surfaces of the shoe mold. (3) The shoe mold is divided into two pieces, and the two are expanded using a screw or the like.

[0024] In this preparation, a shoe last having an appropriate width is usually obtained by trial and error. However, with experience, the desired shoe last can be obtained once according to the measurement record. In particular, if the semi-finished shoe product uses the above-mentioned slits and the method of using the stamp of (4) or (5) or clay as the measurement recording method, the extension amount of the width becomes clear as the width of the slit. Since it can be determined to, especially (2) above
The preparation method for adhering the sheet pieces is easy, and it becomes possible to obtain a desired shoe last in a short time with a short-term experience.

The shoe mold thus prepared is put into the inside of the above-mentioned semi-finished product of shoes, and the surface portion of the outsole is adhered to complete the shoe. The shoe will fit exactly on the customer's foot.

The above is a semi-finished shoe product when measuring and recording,
Although the semi-finished shoes to be completed by adhering the outsole surface portion are the same, they may be different. That is, the same semi-finished shoes as the ones to be completed are prepared for measurement as the semi-finished shoes to be measured and recorded, and a plurality of semi-finished semi-finished products with different tightening strength are prepared. . Of course, the color of this semi-finished shoe for measurement,
You only need to prepare one type of design. Thus
For the measurement, the one with the tightening force that suits the customer's preference is selected and used, and the semi-finished shoe product to be completed has the design of the customer's preference.

In the shoe thus completed, not only the size fits the customer's foot, but also the foot tightening force meets the customer's preference.

Next, regarding the third method of manufacturing shoes of the present invention,
This will be described in detail with reference to FIGS. This manufacturing method is
In the second manufacturing method described above, the shoe sole can be made thinner.

In this manufacturing method, the outsole 50 shown in FIGS. 7 and 8 is used. The outsole 50 includes a outsole front portion 51 and an outsole rear portion 52.
Is formed by adhering, and the two can be separated by peeling off the adhering portion, and further, the outsole front part 51 can be replaced with another outsole front part 51 ′. Outsole front part 5
1 has slits 53, 53 extending in the front-rear direction and can be expanded and contracted in the width direction, and a book bottom front part 51 'has a flat plate shape similar to a normal book bottom.

In this manufacturing method, the outsole 50 is used and the outsole front part 51 is attached to form a semi-finished shoe product. At this time,
An adhesive agent having a weak adhesive force is used for the front part 51 of the bottom of the bottom so that it can be easily peeled off. This semi-finished shoe product is placed in a retail store and thereafter used in the same manner as in the second production method.
That is, when the customer selects this semi-finished shoe, the semi-finished shoe is put on the foot and the outer shape of the semi-finished shoe is measured and recorded. Next, a shoe mold corresponding to the above measurement record is prepared and put into the inside of this semi-finished shoe, and the outsole front part 51 is peeled off and removed, and the outsole front part 51 ′ is bonded instead. For this adhesion, a normal one, that is, a strong one that does not easily come off is used.

The shoe thus completed is light and supple because the sole does not become double as in the above-mentioned manufacturing method.

In the above description, the stretchable bottom bottom front portion has a slit, but it is possible to prepare various rubber sheets, elongated holes, etc. having different tightening forces. In this way, the front part of the outsole of the semi-finished shoes can be replaced with the one with the tightening force of the customer's preference, and the measurement record can be made. Can be

[0033]

As described above, in the shoe according to the first aspect of the present invention, since the width of the sole can be expanded and contracted, it is only necessary to adjust the size of the foot, that is, the length of the foot in the front-rear direction. It will be suitable for. Therefore, the user can easily obtain shoes that are suitable for the foot. Also,
When the user stands for a long time, the foot becomes thicker and the shoe becomes tighter. However, since this shoe also copes with this shape change, a good comfort is always obtained. Further, it is not necessary for the shoe manufacturer and the seller to prepare a large number of wise shoes according to the width of the customer's foot, and the stock quantity can be reduced. Further, in this shoe, if various kinds of foot tightening forces are prepared, not only the size of the foot can be matched but also the tightening force can be matched to the customer's preference.

If the slit is used as the structure which can be expanded and contracted, the structure becomes extremely simple and practical.

In the first method of manufacturing shoes according to the present invention as set forth in claim 3, since the shoes are stored in the state of semi-finished products and the width is set according to the order to complete the shoes, the width is different. Since it is not necessary to store many kinds of shoes in stock and only one kind of shoes having a width of one kind is stored, it is possible to reduce the amount of stock and prevent out of stock. Also, from semi-finished shoes,
Since the shoe is manufactured by simply adhering the front part of the outsole, anyone can easily and quickly perform the process.
Moreover, the types of shoe molds required for this are significantly smaller than the types of shoes, so this bonding work can be performed not only at the factory but also at wholesalers and retailers, and the delivery time is extremely short. You can

According to the second method of manufacturing a shoe of the present invention as defined in claim 4, the shoe is completed by storing the shoe in a semi-finished product state and setting the width according to the customer's foot. Can be adjusted to Moreover, if a semi-finished product for measurement is used, it is possible to adjust the tightening force when the shoe is put on. Further, after the customer places an order, the outer shape of the shoe is measured and recorded, and only the work of adhering the front part of the outsole is performed, so that the desired shoe can be completed easily and in an extremely short time. . Therefore, by performing these operations at a retail store, it is possible to provide shoes that are made to order or more appropriately matched in almost the same time as when purchasing ready-made shoes. Further, similar to the above-mentioned manufacturing method, it is possible to omit the stock of many kinds of shoes having different widths and reduce the stock quantity.

In the third method of manufacturing a shoe according to the present invention as set forth in claim 5, in addition to the advantages of the above-mentioned manufacturing method, the shoe sole is not doubled as in the above-described manufacturing method, and is light and supple. .
