Abstract

(57) [Summary] [Purpose] A fine depression that stimulates the sole of the foot can be easily and surely formed on the upper layer surface of the insole that glides well and looks beautiful. [Structure] On the upper side of the male lower layer surface 1, female concave protrusions 7, 7, ... Extruded by the male concave protrusions 2, 2, ... Formed on the surface of the male lower layer surface 1 are formed on the surface. The female upper layer surface 3 is heavily bonded via the adhesive 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an insole laid inside a shoe, and more particularly, to an insole formed of two layers, in which an upper layer surface formed by pressing a depression on a lower layer surface is laminated. is there.

[0002]

[Prior art]

 Conventional insoles are usually made by using a single material such as synthetic rubber, synthetic resin, PVC, etc. to form a single layer, and a material for forming the upper surface that makes the upper surface look better, For example, it is manufactured by a method in which synthetic leather, leather, etc. are layered and heated and pressure is applied to attach the two layers.

[0003]

[Problems to be solved by the device]

 Among the conventional methods for manufacturing insoles, the one manufactured by the former method has more layers, so the colors of synthetic rubber, synthetic resin, etc. are as they are, so the colors and slippage are poor. However, there is a drawback that it does not look good, and the latter method of pressing two layers and pressing them while heating is because the fine protrusions melt due to heating and the shape collapses, so a fine protrusion is expressed. In addition to being technically difficult to do, there was a problem that it took a lot of time and labor to attach the two layers. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to form a male recess having a small diameter of about 0.5 to 3 mm on the lower surface. It aims to provide a nice-looking insole that expresses fine depressions on the surface by simply pressing the protrusions against the upper surface that looks good from the back side as well. Is.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the insole of the present invention supplies a hard plastic material into a mold, and first molds a lower layer surface having a fine hemispherical male concave protrusion on the surface of the mold. Take it out of the mold, and then press the upper layer surface, which is made of soft synthetic leather, on the side of the lower layer surface where the male depressions are provided, superposed and polymerized with adhesive glue, and press it with a sponge from the top and bottom. And press the formed male depressions on the lower surface strongly against the upper surface side.``When forming the female depression projection surface by extrusion molding on the upper surface, the lower and upper surfaces are superposed at the same time. To do.

[0005]

[Action]

 The silhouette of a fine, roughly hemispherical male recess that has already been molded on the lower layer is surely extruded.It is formed on the upper layer by molding, and the fine recess formed on the upper layer is used on shoes when wearing shoes. Stimulates the soles of the feet.

[0006]

【Example】

 An embodiment will be described with reference to the drawings. In FIGS. 1 to 4, a male lower layer surface 1 is a plastic material such as vinyl chloride resin in a molding die K in which a desired depression is formed on the inner surface. Is injected and mold-molded by a method such as injection molding, and substantially hemispherical male recesses 2, 2, ... With a fine diameter of 0.5 to 3.0 mm are formed on one surface. In this case, the hardness is preferably 90 to 95. The female upper layer surface 3 may be made of, for example, leather or vinyl chloride material, but it is preferable to use a synthetic leather material having a thickness of about 0.5 mm and contact the male surface recess 2 with the adhesive surface side. Adhesive 4 is applied and superposed on the male recesses 2, 2, ..., And about 50 tons by a press 6.6 through a sponge 5.5 having a hardness of about 80 and a thickness of about 10 mm from above and below. By pressing with a pressing force of -80 tons for about 5 seconds, the male concave protrusions 2, 2, ... Are formed on the surface of the female upper layer surface 3 by extrusion molding, and at the same time the male lower protrusion is formed. The layer surface 1 and the female upper layer surface 3 are heavy-bonded to form two layers.

[0007]

[Effect of device]

 As described above, since the insole of the present invention can extrude and bond the upper layer surface of a beautiful color without heating due to the male recess of the lower layer surface, when used in a shoe, the blood circulation of the sole of the foot It is possible to provide an insole which has fine depressions for improving the wear, which is slippery and looks good at low cost.
