Description

Prefabricated Shoes {A self-assembly shoes}

The present invention relates to a prefabricated shoe, which will be described in more detail so that each component of the shoe can be easily detached and assembled without the use of sewing or adhesive, and prefabricated so that each component can be replaced when old and damaged. To provide shoes.

Generally, various shoes such as slippers, sandals, shoes, and sneakers are mainly divided into soles and uppers, and the uppers are combined by using sewing or adhesives on the soles. There was a problem in that the shoe could not be used because the upper part was easily detached from the sole because the sewing was dropped or the adhesive had reached the end of the life of the sole and the upper, and the joint was not repaired and reused. In addition to the downsides, when the sole part is worn out or damaged due to the aging of the sole, the sole cannot be replaced. Therefore, the entire shoe must be purchased regardless of the old or damaged part. will be.

In order to solve the problems of the conventional general shoes, a number of shoes have been developed to be made as a prefabricated as in the following prior art document, Republic of Korea Utility Model Publication 20-1989-0001989 (March 25, 1989) or Korea Korean Patent Laid-Open Publication No. 10-2005-0013028 (2005.2.2.) Discloses sneakers in which the soles and uppers are assembled with zippers, or shoes in which uppers and soles are connected by bolts and nuts, but such conventional prefabricated sneakers are described. Shoes are separated only a part of the components of the entire shoe, the remaining components are all made using the existing sewing or adhesive, and for the assembly of the shoes separate from the shoe components of the zipper or bolts, nuts There was a disadvantage to have an assembly means such as.

In addition, Korean Utility Model Publication No. 20-1992-0007612 (1992.10.16.) Describes a configuration in which the sole consists of a main body and a pallet inserted into the lower part of the assembly slipper so that the sole is composed of the main body and the pallet. , Republic of Korea Utility Model Publication No. 20-2010-0011161 (2010.11.17.) Discloses a configuration in which the base having a plurality of fixing parts and the band to be detachably attached to the fixing part is made to be assembled, but these Also, in shoes such as slippers, only the pallet of the sole is separated and assembled, or only the band corresponding to the upper is assembled to the sole, so that only some components are detached, so the overall configuration of the shoe is the basic configuration of the outsole, midsole, insole, and upper. Even if it is made only of the components of each part can not be separated independently because the aging and damage of each part There was a limit in the repair and replacement of the city, which could not completely solve the problem of having to purchase a whole new shoes in case of partial aging and breakage.

Accordingly, in the slipper consisting of the sole and the upper divided into insoles, midsoles, and outsoles, as in the pre-registered Korean registered utility model 20-0449828 (2010.8.6.), The insole, midsole, outsole, and upper are assembled. And disassembled so that when the part of the slipper is old and damaged, only the member of the old and damaged part can be repaired and replaced without having to purchase a new slipper. However, the pre-registered utility model of the present inventors As it is made by assembling, rainwater flows in between the upper and midsole of the slipper and into the upper surface of the insole inside the slipper, so it cannot be used as shoes or sports shoes. Used to connect upper band and midsole coupling groove or insole lower and outsole coupling stones. Combining means each attached to the machine consists mainly of a magic tape when a strong external force acting on the slipper had the problem that the upper and middle soles, insoles and outsoles are easily separated and the assembly strength falls.
