Description

Adjustable shoes {THE FOOTWEAR OF LENGTH REGULATION}

The present invention relates to a shoe, and more particularly, to a shoe that can be adjusted in length by fixing the length adjusting device without using a tool such as an adhesive to the midsole and the side of the shoe.

Shoes are worn by men and women of all ages in terms of foot size and design form, or functional aspects. The types of shoes include sneakers, shoes, and slippers, and according to the purpose of wearing shoes, Shoes for a variety of purposes are being created to suit a wide range of activities, including mountain, body correction, and specific sports.

Shoes are made of various sizes according to the size of the foot, that is, shoes are manufactured by increasing the size of the shoes step by step to have a certain dimension (generally about 5 ~ 10mm) between each size of the shoe.

As such, as the size of the shoe is not uniform and is made uniform so as to be gradually increased by a certain dimension, there have been the following problems.

In the case of a fast-growing child, the shoes are not old enough to wear small.

The present invention has the purpose to increase the length of the shoe in accordance with the above steps in accordance with the above steps to allow the shoe to be extended for a certain period of time to improve the economics.

To this end, the upper portion of the upper and the sole of the sole is formed by the pleats, so that even if the shoes are stretched, the side does not become excessive, and the length of the sole can be adjusted in a sliding manner at the bottom of the sole at the bottom of the pleats.

The length adjustment shoes of the present invention as described above can purchase and use shoes, and as the foot grows and the shoes become smaller, the shoes can be stretched and used as much as the shoes grow, so that the shoes can be adjusted and worn as the foot grows, which can give economic effects. have.

Hereinafter, with reference to the accompanying drawings will be described in detail the features and configuration according to a preferred embodiment of the present invention.

Figure 1 is a perspective view of the adjustable length shoe 10 of the present invention, Figure 2 is a description of the length adjustment portion of the adjustable length shoe 10 of the present invention, Figure 1 is the sole of the adjustable length shoe 10 of the present invention (11) A partial sectional view.

As shown in FIG. 2, the sole 11 and the middle portion of the length adjusting shoe 10 are formed as wrinkles 13.

In addition, the middle portion of the sole 11 is configured to be adjustable in length in the sliding form.

A locking protrusion 22 having an elastic member is formed at both ends of the middle portion and protruding the locking jaw 23 at both inner end surfaces so that the locking groove 21 can be elastically caught by the elastic member.

The locking jaw 23 prevents the locking protrusion 22 from being separated.

The locking groove 21 is formed at regular intervals and can be adjusted according to the size of the shoe and is based on having three or more adjustment units.

Therefore, the extending portion 14 of the sliding type is formed of a flexible body of the elastic material.

To increase the length, the user grasps the epithelium 20 with one hand, grabs the heel portion of the sole 11 with one hand with the other hand, and pulls together, and the locking protrusion 22 formed on the middle portion of the shoe slides and locks. After being separated from the groove 40 and adjusted to an appropriate length, the locking protrusion 22 is fixed to the appropriate locking groove among the locking grooves 40 formed in the cross section of the shoe to fix the shoe.

At this time, the locking protrusion 22 is not easily separated from the locking groove 21 by the elastic force of the elastic member formed in the shoe to firmly fix the shoe.

Although the technical spirit of the present invention has been described in detail according to the preferred embodiment, the above-described embodiment is for the purpose of description and is not intended to be limited to the above-described embodiment. Those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
