Abstract

(57) [Abstract] [Purpose] A shoe that has moderate hardness and cushioning properties and is a pad body that is easy to hold, and that can be easily modified into a required shape by means such as heating and grinding after molding. The purpose is to provide a pad body for use in the bottom. [Structure] A corrugated grain 1 and a non-woven fabric fiber 2 made of nylon fiber, and a synthetic resin having thermoplasticity such as ethyl vinyl alcohol (EVA), polyethylene, isoprene, rubber, etc. which softens at 50 ° C. or higher and hardens at less than 50 ° C. Mixing the binder 3 which is a single or a mixture of two or more kinds,
A softening-deformable original plate formed by molding means into a desired shape corresponding to either the arch part or the heel part is used as the toe part pad 4, the arch part pad 5, and the heel part pad 6, which is required for each individual. This is a structure in which the shape of the sole can be modified by heat deformation using a dryer or the like, or paper grinding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a pad body that is used between a sole and an insole.

[0002]

[Prior art]

 Conventionally, a pad body has been devised, put into practical use, and publicly known, in which a urethane sponge material is interveningly used in a shoe sole formed into a shape corresponding to any of a toe portion, an arch portion, and a heel portion.

[0003]

[Problems to be solved by the device]

 However, since the pad body made of urethane sponge material is soft, it is possible to secure the cushioning property required for normal walking, but it is very fragile and can be used like sports shoes. Even if it is used in the shoe sole where it is required to be used, the foot cannot be easily compressed and deformed or ruptured by the foot, resulting in a meaningless use of the pad body. There is a problem to be solved in that it cannot be processed to transform the formed original plate into a shape that matches the required sole shape of each individual.

[0004] The present invention provides a pad body that has appropriate hardness and cushioning properties and is easy to support, and the inside of the shoe sole that can be easily modified into a required shape by means such as heating and grinding after molding. The purpose is to provide a pad body to be used for the intermediary use.

[0005]

[Means for Solving the Problems]

 The pad body used in the shoe sole of the present invention is a mixture of cork particles and fibers for a non-woven fabric with a binder having thermoplasticity, and this is applied to any desired toe part, arch part, or heel part. The feature is that the original plate, which is formed into a desired shape by a forming means and is softened and deformable by heating, is modified by heating or grinding so as to match the sole shape of each individual.

[0006]

[Action]

 The pad body of the present invention having the above-described structure can be easily supported by the legs having appropriate hardness and cushioning property, and can be formed into any desired shape by heating or grinding after molding. It becomes easy to deform.

[0007]

【Example】

 FIG. 1 is a plan view of a set of pad bodies according to the present invention, and FIG. 2 is a partially enlarged cross-sectional view taken along the line AA of FIG. 1, showing a cork grain 1 and a non-woven fabric fiber 2 made of nylon fiber. Ethyl vinyl alcohol (EVA) that softens above 50 ° C. and cures below 50 ° C., a synthetic resin having thermoplasticity such as polyethylene, isoprene, rubber and the like, alone or in combination with two or more binders 3 mixed, The softening-deformable original plate formed by a molding means into a desired shape corresponding to any one of the toe part, the arch part, and the heel part is used as the toe part pad 4, the arch part pad 5, and the heel part pad 6. It has a structure that can be modified by heating deformation using a dryer etc. or paper grinding etc. to the sole shape required by the individual, and it is interposed between the sole and the insole consisting mainly of the sole and the insole. And let it be in the middle Wear to be used.

[0008]

[Effect of device]

 As described above, the pad body used in the shoe sole of the present invention is a mixture of cork particles and fibers for a non-woven fabric with a binder having thermoplasticity, and the mixture is mixed with a desired toe portion, arch portion, and heel portion. The original plate that is softened and deformed by heating and formed into a desired shape corresponding to any of the above is modified by heating or grinding so as to match the shape of the sole of each individual. Therefore, it is a pad body that has appropriate hardness, cushioning, heat retention, and breathability as a pad body, is excellent in strength, and has good footing, and is required by means such as heating or grinding after molding. It can be easily modified into any shape and can provide a pad body that fits the soles of different orderers, which is especially required for sports shoes. It is possible to provide a putt body of chrysanthemum.

Claims (1)

[Scope of utility model registration request] 1. A softening deformation by heating by mixing a cork grain and a fiber for a non-woven fabric with a binder having a thermoplasticity and forming the mixture into a desired shape corresponding to any one of a toe portion, an arch portion and a heel portion by heating. A pad body for use in a shoe sole, characterized in that a possible original plate is modified by heating or grinding so as to conform to the sole shape of each individual.
