水の侵入を防止する必要があった。[0002] A conventional laminated shoe sole has been formed by integrally laminating outer sole and inner sole sheets cut into a contour of a sole using an adhesive or a method such as heat fusion.
Therefore, since the cross section of the laminated sheet is exposed at the peripheral edge of the shoe sole, it is necessary to apply wax, waterproof paint, or the like to prevent water from entering from the edge.

【０００３】また全体が積層構造の靴底は層間で剥離す

ので障害物に引っかかり易いなどの欠点が見られる。Further, there is a problem that the sole of the sole having a laminated structure as a whole has a problem of peeling between the layers, and since the bottom surface of the laminate and the end face are almost perpendicular to each other, the sole is easily caught by an obstacle.

【０００４】そこで本考案は、外周縁において積層物の
断面が露出せず、軽量であり、高強度かつ障害物への引
っかかりの少ない積層靴底を提供する。Accordingly, the present invention provides a laminated shoe sole that is lightweight, has high strength, and is less likely to be caught by obstacles, without the cross section of the laminate being exposed at the outer peripheral edge.

解決される。The present invention relates to a laminated shoe sole comprising an artificial leather outer bottom layer having a silver surface and at least one middle sole layer integrally laminated on a surface opposite to the silver surface. The problem of the present invention is solved by the fact that the outer sole layer at the outer periphery of the laminate having the sole profile is curved toward the opposite surface of the midsole layer to form a bottom shape.

で障害物との引っかかりが少なく、安全である。For this reason, the outer periphery of the sole of the present invention is covered by the outer layer of artificial leather having a silver surface, and since the cross section of the laminate is not exposed, water does not enter therefrom. Further, since the outer sole layer and the middle sole layer are heat-sealed at the peripheral edge, the shoe sole is lightweight and has high strength. In addition, since the outer edge of the outer edge is gently curved from the silver surface to the opposite surface of the midsole, the outer edge is less likely to be caught by an obstacle and is safe.

The shoe sole 10 is formed by integrally laminating an artificial leather layer 12 having a silver surface and a plurality of foamed EVA layers 14 by simultaneous pressing. At the edge 16 of the sole 10, the artificial leather layer 12 curves gently toward the opposite side of the foamed EVA layer to form a ship bottom, so that the edge 16 is covered by the artificial leather layer 12 and the cross section of the laminate. Is not exposed. In this specific example, artificial leather having a silver surface is used as the outer sole layer, and the inner sole is composed of two foamed EVA layers. These may be changed according to the thickness of the entire shoe sole and the thickness of each sheet. Is possible. As long as the outer sole is artificial leather having a silver surface and the innermost inner sole layer is an EVA sheet, the material and the number of intermediate sole layers used in the middle are arbitrary. For example, artificial leather may be used for the inner bottom layer except for the innermost layer.

の靴底１０が得られる。The sole 10 is provided with a female mold having a recess having a three-dimensional shape corresponding to the sole 10, and a mold comprising a flat male mold covering the recess, and an artificial leather having a contour larger than the recess. The outer bottom sheet and the required number of middle bottom sheets are stacked on the female mold, and the male mold can be heated and pressed with the male mold from the side opposite to the silver surface to form the sheet. The softened material at the curved peripheral portion of the depression is subjected to higher pressure than the central portion and flows out of the depression and flows. After molding, the molded product is removed from the mold, and the protruding portion outside the recess is cut and removed to obtain the shoe sole 10 of the present invention.

Preferably, the heel also has an outer sole 12 curved toward the insole 14, similar to the sole body 10, and foam EVA is formed between the outer sole of the heel and the outer sole of the body so that the heel has a desired height. Layers etc. are interposed. The rim member may be simultaneously formed by using a male mold having a cavity having a space shape corresponding to the rim member.

ことができる。The sole 10 of the present invention has a generally flat outer sole 12 surface. Therefore, it is preferable to provide a slip stopper at a required portion of the outer bottom 12, particularly at a portion corresponding to the base of the thumb. FIG. 2 is a partial cross-sectional view of the shoe sole 10 provided with the non-slip member 30. For example, a circular opening 18 is cut out of the outer bottom artificial leather 12 at a portion where the non-slip member 30 is to be mounted, and a metal mold is press-formed so that a curved periphery is formed around the opening 18. Non-slip member 3 having projections or irregularities on the surface of exposed inner bottom 14 in opening 18
0 is attached by bonding or the like. The member 30 is a foamed EVA,
It can be made of elastic sheet materials such as foamed polyurethane and rubber.

In this case, a through hole corresponding to the outer diameter of the cylindrical stud socket 42 having the female screw 44 inside is provided in the outer bottom 12 at a required position, and the base plate 42 is connected to the outer bottom layer 12 so that the stud socket penetrates the outer bottom layer 12. The metal fitting 40 is attached to the shoe sole 10 by interposing the middle sole layer 14 and pressing the outer sole layer 12 and the middle sole layer 14 simultaneously. A tack (not shown) is fixed to the inside of the socket 42 by screw engagement. Depending on the thickness of the outer bottom layer 12, the base plate 46 of the mounting bracket 40 may be interposed between the middle bottom layers 14.

れる。FIG. 4 is a sectional view similar to FIG. 1 illustrating the sole of the present invention according to another embodiment. In the shoe sole 110 according to this specific example, a liquid foamed polyurethane resin composition is injected into the mold on the surface opposite to the silver surface of the artificial leather outer bottom layer 112, and the outer peripheral edge of the shoe sole is formed into a ship bottom shape by internal pressure during foaming. At the same time, the artificial leather layer 112 and the foamed polyurethane inner bottom layer 114 are laminated and adhered to each other to manufacture. When a liquid urethane foam resin composition is used, it has excellent adhesiveness to polyurethane-based artificial leather, so that sufficient adhesive strength can be obtained without applying a primer, an adhesive or the like to the artificial leather layer.

In this case, it is necessary that the artificial leather layer 112 around the opening is pressed tightly against the mold with an appropriate member such as a pin to prevent the injected liquid foamed polyurethane resin composition from diffusing to the silver surface. Similarly, the rim 120 corresponding to the rim member 20 of FIG. 1 can be formed simultaneously with the insole 114 by the foamed polyurethane.

In any case, the weight is excellent and the strength is excellent, water can be prevented from entering from the peripheral edge of the shoe sole, and the advantage of being less likely to be caught by an obstacle can be exhibited.
