Description

[Detailed description of the invention] (Industrial application field) This invention relates to a shoe sole.

(Prior Art) The applicant first installed a reinforcing decorative piece with a pattern on the bottom surface of an opaque shoe sole main body according to Utility Model Application No. 57-93202, and covered this reinforcing decorative piece to create a transparent ground sole. We have proposed a shoe sole in which the pattern on the reinforcing decorative piece can be seen through the ground sole, but in order to form such a sole, a decorative piece is prepared separately and this is attached to an opaque sole. After the main body is formed, it must be glued and set at a specified position on the bottom of the sole body, and then a transparent ground sole must be coated on the bottom of the sole, which complicates the molding process and significantly increases costs. was there. In particular, when the sole body and the transparent adhesive sole are continuously molded by injection molding, the decorative piece setting process is interposed between the sole body molding and the transparent ground sole molding process, which significantly reduces the injection molding efficiency. There were drawbacks.

(Problems to be Solved by the Invention) The present invention aims to provide, at a low cost, a shoe sole in which a clear three-dimensional decorative pattern can be seen through the ground surface using a simple method.

(Means for Solving the Problems) As explained below with reference to the drawings, the present invention provides a ground bottom 1
A shoe sole is characterized in that a notch 11 is provided in the notch 11, and an intermediate sole 2 formed of a colored transparent material having a pattern 21 on the upper surface thereof with a fine unevenness design 211 is exposed and laminated. This is the gist of the invention.

In this invention, the colored transparent intermediate sole 2 is made of a transparent compound rubber vinyl chloride resin, vinyl chloride/ethylene copolymer resin, vinyl chloride vinyl acetate copolymer resin, 1.2 polybutadiene resin, polyurethane, etc. A polymer whose main component is one or a mixture of two or more synthetic resins to which a colored transparent pigment is added, or a fluorescent pigment such as zinc sulfide, zinc silicate, zinc cadmium sulfide, or lucium sulfide is added to these polymers. , strontium sulfide,
Inorganic fluorescent pigments such as calcium tungstate, organic fluorescent pigments such as Lumogen L Yellow, Lumogen Yellow Orange, and Lumogen L Red Orange, or plastic powders such as formalin condensation resin, acrylic resin, and vinyl chloride resin, Rhodamine B, Rhodamine 6G, etc. , a dye dyed with a fluorescent dye such as Azosol Brilliant Yellow 6G (in the present invention, such dyes are referred to as fluorescent pigments) is added to 100 parts by weight or less of the polymer, and if necessary, It is preferable that the material is formed by adding a colored transparent pigment to a fluorescent pigment.

When adding a fluorescent pigment, if the amount added is less than that, the modification effect of the fluorescent pigment, that is, the sharpness of the pattern 21 will decrease,
Moreover, if the amount added is more than that, the transparency of the intermediate sole 2 tends to decrease, and the sharpness of the pattern 21 tends to decrease.

In the present invention, it is advantageous if the pattern 21 is made to protrude or recess as a whole, since this can give a three-dimensional effect to the pattern 21.

In addition, in this invention, the hardness of the intermediate sole 2 (JISK63
01 Spring type hardness test If the hardness according to type A) is made softer by 10° to 30° than the grounding sole 1, the landing impact can be absorbed by the intermediate sole 2, and the landing stability can be provided by the grounding sole 1. This is convenient because it can be done.

Further, in this invention, the notch 1 of the grounding sole 1 of the intermediate sole 2
If the exposed part 20 for 1 is recessed from the ground contact surface 10 of the ground sole, the exposed part 20 will not be worn and roughened during wear, and the transparency of the midsole will not be reduced, and the midsole will remain clear for a long time. The pattern 21 can be seen through.

Further, in this invention, the ground sole 1 may be colored in a different color from the intermediate sole 2.

The pattern 21 on the intermediate sole can be made to stand out even more.

(Operations and Effects of the Invention) As described above, in this invention, the pattern 21 is formed by the fine unevenness design 211 on the upper surface of the intermediate sole, so when the intermediate sole 2 is molded by injection molding etc., The pattern 21 can be easily formed by engraving a design corresponding to the uneven design 211 on the mold, and since the intermediate sole 2 is transparent and colored, the uneven reflection 211 causes diffused reflection from the notch 11 of the ground sole 1. The pattern 21 with a three-dimensional effect can be clearly seen through.

Therefore, it is significantly cheaper than conventional shoe soles with transparent patterns.

Note that 3 in the drawings is a wedge sole that is laminated and molded on the upper surface of the intermediate sole 2.
