Description

TECHNICAL FIELD The present invention relates to a healthy shoe that has the ability to prevent foot fatigue and maintain foot health, and a method for producing the same.

[Conventional technology]

The human sole has three arches, two inside and two outside.
Two vertical arches and a lateral arch of the forefoot are made, especially the inner vertical arch is made large so that it can be seen from the outside as an arch. These arches serve as springs that soften the cushion of landing during walking and help the weight load applied to the sole of the foot from the outside to the inside. If the load is continued for a long time, not only the fatigue of the muscles of the foot but also the talus head of the foot is pushed down, the scaphoid is deteriorated, the plantar fascia is overstrained, and the triangular ligament is overstrained. The skeletal structure of the foot deforms in the order that the heel warps,
Scholars have reported that the arch is depressed, resulting in fatigue, leg pain, or leg deformity.

Therefore, there is provided a health shoe having an arch cushion that projects so as to push up the inner arch portion of the foot from the inner surface of the bottom of the shoe.

[Problems to be Solved by the Invention]

As shown in FIG. 7, in the conventional health shoe, an arch cushion 2 formed of a material having a cushioning property such as sponge is fixed to a portion of the insole 1 corresponding to the inner arch portion of the foot, and the arch cushion. Since the insole 3 is used to cover 2 with the insole 3, the manufacturing process is complicated and the manufacturing process is troublesome, and the manufacturing cost is relatively high.

The present invention aims to influence a health shoe and a method for producing the same that can eliminate such drawbacks.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention covers a shoe type having a recessed part which is recessed after the inner arch part of the foot and covers the shoe upper with a material such as nonwoven fabric which is easily deformed by pressing. Suspend it on the molded insole, and place a shoe bottom molding die on the lower surface of this insole and the outer surface of the shoe cover, facing the archion, and put a urethane resin and other shoes in the die. A bottom molding material is put in to form a shoe bottom, an arch cushion, and an outer arch, and at the same time, the sole bottom surface is bottomed.

[Action]

A shoe bottom molding material is placed in a mold to mold the shoe bottom, and at the same time, the shoe bottom material pushes up the insole to form an arch cushion integrally with the shoe bottom at a portion corresponding to the recess of the shoe mold.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
4 is a shoe shape, and in its bottom part, a recessed part 5 which is scooped out following the medial arch part of the foot, and a recessed part 6 which is scooped out in the form of a midfoot pad that presses the part forward of the stepped part of the sole of the foot.
Have and. Reference numeral 7 denotes a shoe upper. The shoe upper 7 is covered with a shoe mold 4 as shown in FIG. 2, and the lower peripheral edge of the shoe upper 7 is suspended from an insole 8 formed of a material such as nonwoven fabric which is easily deformed by pressing. Then, spaces 9 and 10 are formed inside the shoe upper 7 and the insole 8 corresponding to the recesses 5 and 6, respectively.
The other parts are in close contact with the shoe mold 4. A gap 12 is formed between the insole 8 in this state and the rubber outsole 11, and a shoe bottom molding die (not shown in the drawing) together with a portion of the outer surface of the shoe cover facing the arch cushion. When the urethane resin liquid is injected into the gap 12, the urethane resin foams and adheres to the insole 8 and the outsole 11 to form the shoe bottom 13, and at the same time, the concave portion 5 and the concave portion of the urethane resin are formed. A portion corresponding to 6 is raised so as to fill the middle portions 9 and 10 while deforming the insole 8 by the foaming pressure as shown in FIG. 4, and the arch cushion 14 and the midfoot pad 15 are integrated with the socks bottom 13. Molded. At the time of molding the arch cushion 14, an outer arch 16 protruding from the shoe sole 13 is simultaneously molded on a portion of the outer side surface of the instep 7 facing the arch cushion 14. The outer arch 16 acts to reinforce the arch cushion 14 so that it will not escape by the foot pressure of the wearer.

The present invention is not limited to the above-described embodiment, and for example, not only a non-woven fabric but also two non-woven fabrics are stacked on the insole 8 and a resin film is sandwiched between them, and other pressures at the time of forming the shoe bottom. In some cases, various materials that are easily deformed may be used, and the outsole 11 may be omitted and the insole 13 may be directly molded on the insole 8 with urethane resin.
13 may be molded with a material other than urethane resin, and the foot pad 15 may be omitted from the shoe mold to create an arch cushion.
A shoe mold in which only 14 is molded may be used, and the lunar core in the shoe upper 7 may be extended to a portion facing the arch cushion 14 and used for reinforcement, and the design may be appropriately changed.

〔The invention's effect〕

Since the present invention is configured as described above, since the arch cushion or the arch cushion and the insole pad can be formed at the same time when the shoe bottom and the outer arch are formed, the manufacturing process of the healthy shoe is simplified and the production efficiency is improved. By further improving it, the production cost can be reduced. Further, since the arch cushion is reinforced by the outer arch so as not to escape due to the foot pressure of the wearer of the shoe, there is an advantage that the comfort of wearing the shoe is not deteriorated.
