Abstract

The present invention relates to a shoe insole (shoe sole) laminated with a shoe sole having an air cushion layer by forming numerous unit air tight seals of the same or different shapes as a rubber material inside the sole surface. The protruding part is formed to have an excellent air cushion layer by rubber and airtight seal, and at the same time, it can be expected to have acupressure effect by the protruding part, and also to a shoe sole having an air cushion layer which can continuously preserve the cushioning function and the acupressure effect even after long-term use. It is about.

Description

Shoe sole with air cushion layer {THE SHOE SOLE HAVING RUBBER CUSHION LAYER OF AIR}

The present invention relates to a shoe insole (hereinafter referred to as a shoe sole) in which a shoe sole having an air cushion layer is laminated, and more specifically, to a shoe sole in which numerous hemispherical air cushion layers of rubber material are formed on the surface of the sole.

Conventionally, soles having a cushion function include PVC foam sheets, ethylene vinyl acetate copolymer resin (EVA resin) foam sheets, and other synthetic resin foam sheets in midsole, cut, support layers, and non-woven or fabric layers. Acupressure effect could not be expected with the cushion layer of the layer.

As another example of a conventional shoe sole, the foam foam sheet, the ethylene vinyl acetate copolymer foam sheet, and the urethane soft foam sheet are formed in a second pressurized thermoforming, so that many protrusions are formed, and a cushion function and acupressure effect can be expected at the same time. to be.

However, such a shoe sole has a drawback that the protruding portion is pressed by the pressure of the body's own weight with a prolonged use and eventually loses the acupressure effect as a flat cushion form.

The present invention aims to provide a shoe sole having an air cushion layer by forming numerous unit air chambers of the same or different shape as a rubber material inside a shoe insole (hereinafter referred to as a shoe sole) on which a sole is stacked. As the protrusions are formed by numerous unit air tight seals on the surface layer, it has excellent air cushion layer by rubber and air tight seals, and it can expect the excellent acupressure effect due to the protrusions. Another object of the present invention is to provide a shoe sole having an air cushion layer that can maintain and maintain excellent cushioning and acupressure effects.

Figure 2a to 2c is a step-by-step manufacturing process diagram of the shoe sole of the present invention

The present invention is to solve the problems occurring in the cushioning function and acupressure function of the prior art shoe soles to have a light fit at the same time to understand this more clearly, first to find out the manufacturing method thereof,

In the first step, as shown in Fig. 2a, the sole is dug into a shape of a sole, and the bottom is laid with a certain weight of sheet-shaped vulcanized rubber in a female mold B1 having dozens of hemispherical concave grooves formed thereon, and engaged with the female mold B1. The air cushion layer B3 is formed by pressurizing with the mold B2, and a thin film nonwoven fabric fusing layer B4 of polyester pibar is laminated on the upper layer as shown in FIG. 2B in a two-step process, and the lower layer is polypropylene or polypropylene. The shoe sole is formed of the sheet layer B5 of ethylene (PP, PE) and the hole B6 is drilled at a predetermined interval on the laminated layer, and the shoe sole is covered on the air cushion layer B3 formed in the mold B1. After stacking a sheet-shaped uncured rubber sheet (B7) of a predetermined weight and pressurized with a pressure press (B8) to form a shoe sole as shown in Figure 2c and take it out of the mold and vulcanized in a conventional manner, the shoe sole as shown in Figure 1 This is done.

In the above, the unvulcanized rubber raw material supplied in the female mold B1 is supplied in the form of a sheet and must be molded to a certain distance from the position where the unit air tight chamber B3 'of the air cushion layer is formed on the flat plate. The midsole consisting of the fluoropropylene sheet layer (B5) and the thin film nonwoven fabric welding layer (B4) of polyester pibar is designed to be cut to a certain distance without touching the sidewall (B1 ') of the female mold (B1). When the rubber sheet (B7) is laid on the back and press-molded, the raw material of the unvulcanized rubber sheet (B7) is pressurized by the press pressure, and the edge of the midsole is the sidewall of the female mold (B1). B1 ') is filled with the generated space so that the air cushion layer and the rubber sheet B7 are integrated, and a binding band B7' is formed between both layers of the air cushion layer B3 and the rubber sheet B7. Air cushion layer (B3) and rubber sheet (B7) The rubber sheet (B7) is vulcanized in a state that is deeply bound to the thin film nonwoven fabric welding layer (B4) of the polyester fiber bar fused to the polypropylene pyrostyrene sheet layer (B5), and is pushed between the layers. This does not happen.

The shoe sole B having the air cushion layer manufactured by the above method is an air cushion layer B in which dozens of unit air tight chambers B 'are formed of rubber material, and dozens of holes are evenly distributed underneath. It is directly laminated on the surface of the PP or PE sheet (B5) on which the thin film nonwoven fabric fusion layer (B4) of polyester piba is laminated, and the rubber sheet (B7) layer is provided on the thin film nonwoven fabric fusion layer (B4). Strong adhesive bonding and forming a binding band (B7 ') and at the same time wrap the edge of the PP or PE sheet with a rubber layer together with the upper air cushion to unite, so as to bond the adhesive to the sole of the sole or leans (inclined bar) It can be referred to as a shoe sole having an air cushion layer formed with a thick portion (B3 ~ B7).

The sole manufactured according to the present invention has dozens of binding bands (B ′) formed between the air cushion layer and the PE or PP layer, and the PE or PP layer between the thin film nonwoven fabric welding layer (B4) and the rubber sheet (B7) layer. Heat-sealed nonwoven fabric bar and rubber sheet are strong binding by vulcanization adhesion, so there is no rolling phenomenon between laminated sheets, and unlike the cushion function of conventional foam, you can feel a light cushion texture and keep the shape of the cushion even after long-term use. It is a shoe sole having an air cushion layer that can be continuously preserved and has excellent cushioning function and can be widely used in slippers, shoes, and sneakers.

Claims (1)

The upper layer is an air cushion layer (B3) formed with dozens of unit air tight chambers (B3 ') made of rubber material, and immediately below the dozens of holes are evenly distributed and cleaned. ) Is laminated directly to the surface of the laminated PP or PE sheet (B5), and the rubber sheet (B7) layer is strongly bonded and bonded to the thin film nonwoven fabric bonding layer (B4) and at the same time forms a binding band (B7 '). The air cushion layer having the thick parts B3 to B7 formed thereon is integrally formed by wrapping the edge of the PP or PE sheet together with the upper air cushion with a rubber layer to enable adhesive adhesion or an Arith (inclined rod) to the midsole edge.
