【発明の属する技術分野】本発明は、作業靴等に用いる
靴底及びその製造方法に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe sole used for work shoes and the like and a method for manufacturing the same.

求される。2. Description of the Related Art Shoes are required to have various functions according to their uses. For example, in the case of work shoes used in a restaurant kitchen, the shoes are lightweight and water or oil adheres to the floor. In many cases, the bottom of the shoe sole is required to have excellent slip resistance.

ばりが生じて外観的に見苦しくなったり、耐滑性が低下
することがある。However, since a shoe sole made of a synthetic resin material generally has a large weight, a foamed synthetic resin is used. There is a problem with dimensional accuracy. Also,
If an air vent is provided in order to improve the reproducibility of the design pattern of the shoe sole, the material will get into that part, making it difficult to release the molded product, and sometimes the foam layer may break.
Burrs may appear and make the appearance unsightly, or the slip resistance may decrease.

匠パターンを設けることが困難であり、縦又は横に連続

にせざるを得ず、デザイン的な制約だけでなく耐滑性に
影響を与えている。For this reason, it is difficult to provide a convex design pattern on the bottom surface by the conventional method, and it is unavoidable that the design is linear in a vertical or horizontal direction, or has a wavy design or a circular design with a concave pattern. Not only design constraints but also slip resistance is affected.

る。Further, conventionally, since the shoe sole is formed by molding with a plate-shaped mold having a pattern on the ground contact area, it is cut by punching or the like to form a shoe sole, so that the side surface is exposed and the skin layer is removed. Not only is it ugly in appearance, but also
There is a problem that dirt, such as oil, water, and dust, and mold are likely to adhere to and enter the holes during use. Therefore, the actual Kaihei 5-1
As shown in Japanese Patent No. 3208, a method of covering the side surface with foamed polyurethane has been proposed. However, since the foamed polyurethane has a specific gravity of 0.5 to 0.7, the weight increases, and the manufacturing process and cost increase. The problem of inviting
【0006】また、高発泡の合成樹脂は輸送中のコンテ
ナや自動車の車内温度上昇に伴い、変形し易いという問
題もある。Further, there is a problem that the highly foamed synthetic resin is apt to be deformed as the temperature inside the container or the vehicle during transportation rises.

掛かりによるつまずきや剥離を生じ易い。In the conventional method, it was difficult to form a thin rise from the shoe sole, so that oil was added at the boundary with the upper.
Water and dust are likely to accumulate, which facilitates the separation of the sole of the shoe and also causes tripping and separation due to being caught.

First, in order to make a primary molded product, for example, EVA resin (ethylene vinyl acetate copolymer resin) is used as a main component, and slip resistance is also improved. 1 rubber for
From the plate material 1 mixed with about 5% by weight and made into a highly foamed material, as shown in FIG.
As shown in, the shoe sole member 2 having a substantially shoe sole shape is punched out.

The shoe sole member 2 is inserted into the lower mold 4b of the shoe 4.

The bottom and side surfaces are once melted and then solidified to form a skin layer, which improves the surface density.

である。また硬さについては、耐滑性は小さい方が地面
に密着するため好適であり、耐摩耗性は高い方が良い。Generally, it is preferable that the specific gravity of the shoe sole 6 is small in terms of slip resistance and high in terms of wear resistance. With regard to hardness, it is preferable that the slip resistance is small because it is in close contact with the ground, and the wear resistance is preferably high.

いため柔らかく、滑り難くなる。According to various experiments using EVA resin,
Specific gravity is about 0.15 to 0.35, hardness is 45 to 65 °,
It was confirmed that preferably about 50 to 60 ° (SRIS 0101 standard: measured by Asker C type hardness meter) satisfies both the slip resistance and the wear resistance. Outside this range,
It was observed that any of the properties dropped sharply. Further, in the concave-convex pattern 8, the concave portion is compressed and has a higher density than the grounding block 7 serving as a grounding surface, and the grounding block 7 has a relatively low density and a low hardness, and is soft and difficult to slip.
【0023】また、加熱により靴底6の底面、側部には

る。The slip resistance is greatly influenced by the design shape of the uneven pattern 8, and the size of the ground block 7 is 1 to 6 cm.
2 is suitable, and the total area of the grounding block 7 is 35 to 55%, preferably 40 to 50% of the entire bottom surface. Furthermore, each grounding block 7 is preferably rectangular rather than circular, and the larger the component of the horizontal line segment orthogonal to the vertical line segment connecting the toe and the heel, the greater the slip resistance. The ratio of the vertical and horizontal line segments of the block 7 is preferably about 1: 1 to 1: 3, and if the ratio is out of these ranges, the slip resistance decreases.

Through holes 10 having a diameter of about 1 mm are formed in the corners of the portion of the unevenness 5 for forming the grounding block 7 for removing air.

In this heating and compression step, the shoe sole member 2 is not melted enough to flow, so that the material does not leak from the through hole 10. Therefore, scars due to the through holes 10 hardly occur in the grounding block 7 of the completed shoe sole 6.

It is also possible to mold the shoe sole 6 having a partially different hardness.

に優れ、汚れやカビの発生を防止できる。As described above, the shoe sole according to the present invention is excellent in shape stability, slip resistance and abrasion resistance by providing the uneven pattern on the bottom surface and forming the skin layer on the bottom surface and the side surface. It can prevent the generation of dirt and mold.

In addition, by making appropriate adjustments, it is possible to obtain a shoe sole that is lightweight, has improved shape stability and dimensional accuracy of the product, and is capable of preventing stains and mold from occurring. In the secondary molding, since heat compression is performed again for the primary molding, heat resistance, shape stability, and dimensional accuracy are improved by the annealing effect, which is effective in preventing deformation during transportation.
