Description

  The present invention is firmly and stable in the assembled state, even though it is configured to be removable so that it can be combined and removed without bonding the outer shoes, inner shoes and outsole. The present invention relates to a snap-fit shoe that can provide a comfortable wearing feeling.

  Shoes that have been used to protect legs while walking on two legs have developed new materials as science and technology develop, and today, home, walking, mountain, body correction, special exercise Various shoes are made to suit various activities such as for use.

  FIG. 1 is an exploded perspective view showing the structure of a conventional shoe. Referring to FIG. 1, a conventional shoe generally includes a sole (outsole) 10, a midsole 20, and an upper 30. The outsole 10 is a portion where the bottom portion is landed on the ground when the shoe wearer walks, and is generally made of a rubber material to prevent slipping, wear resistance, and landing force on the ground. Is. The outsole 10 may have a flat bottom surface or a flat structure, and a cushion protrusion may be formed in a through hole penetrating the side surface or in a space inside the through hole. The midsole 20 is made of natural rubber, synthetic rubber, or synthetic resin such as polyurethane foam or polypropylene, and is bonded to the upper portion of the outsole 10 to serve as a cushion that absorbs an impact applied to the sole of the foot during walking. The upper 30 is formed on the upper portion of the midsole 20 so as to cover the legs of the wearer, and an insole (insole) 35 that is in contact with the sole of the wearer's legs is formed inside the upper 30. The insole 35 is laminated so as to cover the upper surface of the midsole 20, and the midsole 20 and the upper part of the insole 35 are usually covered with an upper 30.

  Such shoes generally require a process of bonding the outsole 10 and the midsole 20 or the outsole 10 and the upper 30 with an adhesive during the manufacturing process. Adhesives used to bond shoes generally use organic solvents as solvents, but the bonding process is difficult due to the toxic odor generated by the adhesive during the adhesive application process, and environmental problems are caused by toxic substances. In addition, there is a problem that the labor cost of manpower and the production time for the bonding work increase.

  At this time, the method of heating the adhesive used in the bonding step can be classified into a hot air heating method and an induction heating method. However, the hot air heating method applies high-temperature energy to the general part of the material after the adhesive is applied, so it is easy to cause damage to the material. The induction heating method is essential as a method for generating heat at the bonding site using induced current. In addition, since the metal forming mold or the metal plate must be provided, not only the manufacturing cost increases, but also there is a problem that various forms of the product cannot be formed. In particular, adhesives used in shoes can have a reduced adhesive strength or damage over time, which can cause discomfort in wearing and using the shoes.

  In order to solve such problems, conventionally, a snap fit shoe capable of separating an outsole or an insole from an upper has been disclosed. For example, Japanese Patent Application Publication No. 10-2010-0050273 (a sandal having a replaceable insole) is configured such that the insole of the sandal can be replaced, thereby extending the service life of the sandal. Japanese Patent Application Publication No. 10-2010-0050274 (snap-fit shoes with a functional outsole) includes at least a pair of assembly means so that both sides of the outsole and the upper can be assembled with each other. In addition, registered patent publication No. 10-1054622 (assembled shoe) has an outsole formed with a plurality of coupling protrusions protruding from the bottom and an upper formed with a coupling hole selectively sandwiched between the coupling protrusions. It is configured as possible.

  However, such conventional techniques focus on structures that allow the upper and insole or upper and outsole to be easily separated or joined. As a result, the insole and the outsole are easily separated from the upper, which is inconvenient for activities while wearing shoes. In particular, the conventional technology forms a protruding assembly in some areas so that the upper and the outsole, or the upper and the midsole are easily separated, so that the upper can be used in situations where the wearer does not want it. The problem of separating the insole and outsole can occur.
