[Structure] A sheet material formed by crushing open-cell synthetic resin foam is punched into a predetermined shape, a solvent-inert coating layer is formed on both side surfaces thereof, and heat is applied to the outside of each coating layer.
Or, an adhesive layer that can be reactivated by a solvent is provided.
Further, a sheet material formed by crushing open-cell synthetic resin foam is punched into a predetermined shape, and a solvent-inert coating layer is layered on both side surfaces of the sheet material.
A core material such as synthetic leather is adhered, and an adhesive layer that can be reactivated by heat or a solvent is provided on the outer surface of the core material and the coating layer.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a core body such as a heel portion and a toe portion of a shoe.

[0002]

[Prior art]

  Traditionally, polyurethane foam, leather and synthetic leather shoe cores have already been used. ing.

[0003]

[Problems to be solved by the device]

  The polyurethane foam products described in the above conventional technology are soft and light. It has excellent quantitative properties, but has the drawback that it easily loses its shape. Also, those made of leather or synthetic leather are rigid. , Is excellent in shape retention but inferior in softness, which causes slippage of shoes.     The present invention has been made in view of the above problems of the prior art. , Its purpose is excellent in shape retention and elasticity, and there is no fear of deformation, and An object of the present invention is to provide a core body capable of preventing slippage of shoes.

[0004]

[Means for Solving the Problems]

  In order to achieve the above object, the core body of the present invention is an open-cell synthetic resin foam. The sheet material formed by crushing the body is punched into a predetermined shape, and both sides of the sheet material are Layers of active coating layers can be reactivated by heat or solvent on the outside of each coating layer That is, the adhesive layer is provided. Also formed by crushing open-cell synthetic resin foam The formed sheet material is punched into a specified shape, and a solvent-inert coating layer is layered on both sides of the sheet material. A core material such as leather or synthetic leather is adhered to one side of the core material with an adhesive, and And an adhesive layer that can be reactivated by heat or solvent on the outer surface of the coating layer Is.

[0005]

[Action]

  The core of the heel and toe of the shoe according to the present invention is resistant to solvent on both sides of the sheet material. Since an active coating layer is layered, it is necessary to apply an adhesive layer on both outer surfaces and Since there is no risk of solvent penetrating the sheet material when reactivating the adhesive layer of The elasticity of the material can be retained, and the sheet material is retained by the coating layers on both sides. Be done.

【Example】

  In FIGS. 1 and 2, reference numeral 1 is a core body of a heel part (commonly called a moon type), which is a continuous body. A sheet material 2 formed by crushing a synthetic resin foam such as urethane foam of foam, The heel portion is punched out, and solvent-inert coating layers 3 and 3 are layered on both sides thereof. And an adhesive layer 4, which can be reactivated by heat or a solvent, on the outer surfaces of both coating layers 3, 3. 4 is provided. Further, in FIG. 3, 1a is a core of a toe part (commonly called a toecap) In the body, the sheet material 2 is punched into the shape of the toe portion, and other configurations are as described above. It is similar to the embodiment. Further, each sheet material of the core bodies 1 and 1a of the heel portion and the toe portion. 2 is provided with slanted thin layer portions 5 and 5a by performing skiving along the outer peripheral edge. It   Further, in the embodiment shown in FIG. 4, a core material 6 such as leather or synthetic leather is provided on one of the coating layers 3 and 3. It is bonded via an adhesive agent 7 and is heated or melted on each outer surface of the core material 7 and the other coating layer 3. The adhesive layers 4 and 4 which can be reactivated by the agent are provided.

[0007]

[Effect of device]

  Since the present invention is constructed as described above, the core body has an appropriate rigidity and a good protection. It retains its shape and does not lose its shape even after long-term use. Since both sides of the are coated with a solvent-inert film layer, they should be protected during production and use. The solvent can be surely prevented from penetrating into the coating material. Therefore, the sheet material Since it can be held, shoe slippage can be prevented.
