Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing shoes, and more particularly to a method for manufacturing shoes having a cushion material on the heel portion.

[0002]

2. Description of the Related Art The loading of a cushioning material on the heel of a shoe is generally done in consideration of the fact that the heel of the shoe is an important part for absorbing shock. As a method of manufacturing a shoe having a cushion material in its part, the method is generally performed as follows. First, temporarily fix the insole to the shoe mold and fish in the instep. Next, the outsole is fixed to the ground contact surface side of the sewn-in instep through a medium such as a shank. Then, the shoe mold is pulled out, a cushion material is laminated on the upper surface of the heel portion of the insole, and the entire laying is laid so as to cover the upper surfaces of the insole and this cushion material.

As described above, according to the method of loading the cushion material after fixing the outsole which is the finishing stage of the shoe, when the cushioning property of the cushion material is deteriorated due to long-term use, the cushion is simply removed. Since the materials can be replaced, there is an advantage that the replacement work is easy.

[0004]

However, in the shoe manufacturing method described above, since the cushion material is loaded so as to be interposed between the insole and the whole lining, if a too thick material is loaded, after the shoe is worn. , A part of the whole sheet will be raised, which gives the wearer an unpleasant feeling. Therefore, as the cushioning material, one having a relatively small thickness (usually, a thickness of 2 to
There is no choice but to be limited to about 3 mm). That is, the conventional shoe manufacturing method has a problem in that it is not possible to load a cushion material having a thickness that can sufficiently improve the wearing feeling (per foot).

The present invention has been made to solve the above problems. That is, it is an object of the present invention to provide a shoe manufacturing method in which replacement work is as easy as in the conventional case and a cushion material having a desired thickness that can sufficiently improve the wearing feeling can be easily loaded.

[0006]

In order to achieve the above-mentioned object, a method of manufacturing a shoe according to the present invention comprises a step of temporarily fixing an insole to a shoe mold, a step of fishing in an instep, and an instep and an instep. In the method of manufacturing a shoe, which comprises a step of pulling out the shoe mold after fixing the outsole to the ground contact surface side of the sole, and a step of laying an entire lining covering the upper surface of the insole, as the insole, A lid member having a flange portion projecting from one end surface is used as a pre-step of the step of temporarily fixing the insole to the shoe mold by using the one having a through hole formed in the heel portion in advance. Is fitted into the through hole so as to project toward the grounding surface side of the insole, and the step of removing the lid member before fixing the front bottom to the grounding surface side of the instep and insole, Before the step of laying the entire bed, the step of loading the cushion material into the through hole is included.

[0007]

EXAMPLES The method for manufacturing shoes according to the present invention will be described in more detail with reference to the examples shown in FIGS.

As shown in FIG. 1, the shoe manufacturing method according to this embodiment comprises the following steps. First, the insole 3 (see FIG. 2) having a circular through hole in the heel portion is prepared, and the lid member 12 fitted into the through hole 3a is fitted into the through hole.
The material of the lid member 12 is generally the same as that of the shoe mold 1, but is not particularly limited as long as it is removable. Here, the shape of the lid member 12 is not particularly limited as long as it can close the through hole 3a, but, for example, as shown in FIG. 1A, the thickness is substantially the same as the thickness of the insole 3. It is possible to use a disk which is the same and is formed on a disk having substantially the same diameter, and further has a flange portion 12a protruding outward on one surface. Then, the through hole 3a of the insole 3 is fitted with the surface on which the flange portion 12a does not project from the ground surface side as the tip,
The flange portion 12a is projected to the ground contact surface side of the insole 3. When the through hole 3a is formed in the shape of a triangle, a quadrangle or the like, it goes without saying that the lid member 12 is also formed in a plate of a triangle, a quadrangle or the like.

Next, the insole 3 to which the lid member 12 is fitted.
Is temporarily fixed to the shoe last 1. As shown in FIG. 1 (a), the temporary fixing is usually made by driving tacks 11, 11, 11 at least at three points on the lid member, at least in the vicinity of the tip portion and the step portion of the insole. The lid member 12 is
Since it is used for temporary fixing, the insole 3 needs to be fixed without coming off when the tack 11 is driven.
Therefore, as described above, the flange portion 12a needs to be mounted so as to project toward the ground contact surface side of the insole 3. Insole 3
If necessary, cover the shoe former 1 with a toecap and a lunar core (both not shown) embedded in it and fix it to the insole 3 by fishing it in further. To do.
(See Figure 1 (b))

Next, the tacks 11, 11, 11 are removed, the above-mentioned lid member 12 is removed, and the through hole 3a is loaded with the cushion material 13 (see FIG. 1 (c)). Usually, the thickness and shape of the cushion material are adapted to the through hole 3a of the insole 3. However, it goes without saying that a cushion material having a larger thickness can be loaded by previously providing the heel portion of the outsole 6 with a recess whose planar shape matches the through hole 3a of the insole heel portion. (See Figure 4). Although it is possible to use sponge or the like as the cushion material 13, in order to prevent stuffiness during wearing, a cushion material having hygroscopicity and moisture retention, or a cushion material 13 ′ as shown in FIG. 3 is used. Can be used. That is, the upper plate portion 13'a and the lower plate portion 13 'are made of an elastic material such as synthetic resin.
b, a plurality of tubular portions 13'c having a substantially circular cross section formed so as to be substantially parallel to each other between the upper plate portion and the lower plate portion, and a connecting portion 13 that connects the peripheral surfaces of the tubular portions. 'd is integrally formed. When such a cushion material 13 'is used, the tubular portion 13'c can be deflected to absorb an impact, and the connecting portion 13'd can prevent over-deflection, thereby exhibiting good impact absorption characteristics. it can.
Here, the drawing shows a structure in which the tubular portion 13'c also forms part of the upper plate portion 13'a and the lower plate portion 13'b, but the present invention is not limited to this, and the tubular portion 13'c is not limited thereto. It is also possible to form independently the'c and fix it to the upper plate portion 13'a and the lower plate portion 13'b.

Thereafter, the outsole 6 is attached with an intermediate material (not shown) such as a shank interposed. After finishing the finishing process such as the edge cutting work around the outsole, the shoe mold 1 is removed, and the whole lining 2 is laid on the upper surface of the insole 3 (see FIG. 1D). As a method for attaching the sole of the shoe, Goodyear-welt type, cemented type, McKay type, stitch-down type, etc. can be applied.

In the above-described embodiment, the cushion material 13 is loaded before the step of fixing the front sole 6 to the ground contact surface side of the upper 4 and the insole 3, but the front sole 6 is fixed. After removing the shoe mold 1, the cushion material 13 may be loaded into the through hole 3a from the upper surface of the insole 3. According to the method for manufacturing a shoe having such a cushioning material, as compared with the conventional case where the cushioning material 13 is inserted between the insole 3 and the entire lining 2, the through hole 3a in the insole is provided. Since it can be loaded into the space formed by the above, it is possible to easily load the relatively thick cushioning material 13 having substantially the same thickness as the insole 3. Also, the cushioning material may be damaged due to long-term use,
When the cushioning property is deteriorated, the entire lining 2 can be simply removed and replaced as in the conventional case. Furthermore, the shoe manufacturing method according to the present invention does not significantly change the conventional steps, and thus is relatively easy to introduce.

[0013]

According to the method of manufacturing a shoe having a cushion material on the heel portion according to the present invention, a through hole is previously formed at a predetermined position of the insole heel portion, and a lid member fitted to the through hole is temporarily fixed. However, since the sole is bottomed, a cushion material having a sufficient thickness can be loaded to improve the feeling of wearing. Also,
The cushion material replacement work is as easy as the conventional one because it is only necessary to remove the entire lining.
