Abstract

The present invention relates to an insole to which an upper can be attached and from which an upper can be detached, which said insole comprises a main insole body made of a plastic material constituted in such a way as to comprise an arch-supporting part projecting in an upward curve in order to support the arch portion of the foot of the wearer, and comprises an upper able to be attached to and detached from the upper surface of the said main insole body, and the lower surface of the said upper is covered with a selectively attachable and detachable member. Additionally, with regard to the selectively attachable and detachable upper, the present invention relates to a selectively attachable and detachable upper in which a selectively attachable and detachable member is coated onto the lower surface of the upper and which can be attached to and detached from an insole of a plastic material which is inserted into a shoe. When the present invention described above is employed, there is the advantage that, even though the selectively attachable and detachable member is stably adhered to the main insole body made of a plastic material, it can be detached when a physical force is applied and, additionally, even if detritus becomes stuck to the surface of the selectively attachable and detachable member when it has been detached, the detritus can be easily removed by washing with water and the said upper can be attached to and detached from the insole semi-permanently.

Insoles, commonly called insoles, are curved to correspond to the shape of the sole, and the edges are bent upwards to wrap the bottom of the foot so that the foot is comfortable when wearing shoes. In addition, it is made of a material that can absorb shock when walking to absorb a portion of the shock generated when the foot touches the ground to reduce the fatigue of the foot and serves to reduce the risk of injury.

Insol's materials include all types of plastics available today, depending on the application. Among these, nylon, polypropylene (PP), glass fiber, glass composite, and the like are mainly used. The composite plastic mixture refers to a form in which polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) are used in combination, or a mixture of nylon and glass fiber is used. However, when a pedestrian wears only a plastic insole, the elasticity is weak and the ignition feeling is reduced, and the soles of the foot are hard to come. Therefore, materials such as polyurethane (PU), EVA (Ethylene Vinyl Acetate), and latex have excellent elasticity on the upper surface of the insole. It is used by adding upper. Conventionally, the insole and the upper are provided in the form of the upper attached to the insole upper surface to provide a fixed position in the shoe when walking.

On the other hand, as an insole member for absorbing the impact of walking or softening the insole texture, thermoplastic rubber such as neoprene rubber (NR), styrene butadiene rubber (SBR), butadiene rubber (BR), and chloroprene rubber (CR) TPR, Thermoplastic Rubber) is used. However, when walking, more impact is applied to the rear part than the front part of the foot, so insoles made of thermoplastic rubber become hard on the heel part when worn for a long time, and the rear part of the insole is settled down.

Insole body 12 is manufactured by plastic mold technology. General plastic molding methods vary widely, but are roughly classified into injection molding, compression molding, trans molding, thermoforming, blow molding, film blowing, extrusion molding, calendering, and fiber spinning. Among them, injection molding, compression molding, transfer molding, and rotational molding are a method of pushing and molding a plastic material into a closed mold, that is, a cavity formed between two molds closed to form a molded article.

As a semi-permanent selective detachable member capable of providing an attached state and a detached state, for example, a polyurethane gel may be used to control adhesion by mixing two different types of polyurethane and a curing agent. When two different types of polyurethane and hardener are mixed, the gel becomes viscous and becomes viscous. Thus, it becomes a polyurethane gel having adhesive strength that can be semi-permanently removable as well as attached.

Examples 1 and 2 with low viscosity show the average adhesive strength of 0.84-1.24 (Kg f / cm) which is the highest adhesive force. That is, in Examples 1 and 2, since the viscosity is low, the surface tension is low, and the elongation is about 170 mm, the tendency to maintain the adhesion state with the specimen is strong.
