Description

SOLE-REPLACEABLE SHOES}

The present invention relates to replaceable sole shoes.

Shoes are made up of several layers of sole, each sole performing a different role. Recently, with the increase in leisure activities and sports activities, not only are shoes with various functions and purposes appearing, but as interest in fashion is increasing, people are trying to stock a variety of shoes according to their outfits.

However, it is uneconomical to purchase multiple pairs of similar shoes with only minor differences, such as color differences, and trends often pass before the shoes wear out.

In addition, since most shoes are not made of eco-friendly materials, efforts to minimize shoe waste are continuing.

Accordingly, there is a need for shoes that can replace the sole of the shoe depending on the situation, but are also easy to replace, securely fixed, and, in some cases, prevent slipping.

The purpose of the present invention is to provide a sole replaceable shoe that can replace the sole of the shoe depending on the situation, is easy to replace, is stably fixed, and can even prevent slipping in some cases.

And, it may further include the coupling pin 300 for fixing the upper sole 200 and the lower sole 100 in the vertical direction through the coupling holes 170 and 270.

The coupling pin 300 couples and secures the upper sole 200 and the lower sole 100 in the vertical direction, thereby forming the first and second fitting grooves 110 and 120 and the first and second fitting grooves 110 and 120 formed at both ends of the shoe. The insertion portions 210 and 220 can prevent clearance in the central portion and improve the durability of the shoe by inducing a firm connection.

In another embodiment, the sole replaceable shoe further includes a button 400 that improves the fixation force by pressing the coupling pin 300 in the horizontal direction through fitting from the lower part of the coupling pin 300 to the inside of the upper direction. can do.

The button 400 is inserted and coupled into the coupling pin 300, and can be stably fixed to the lower sole 100 by expanding the diameter of a portion of the coupling pin 300 in the horizontal direction. .

Specifically, the upper sole 200 further includes a coupling pin locking portion 250 on which the coupling pin 300 rests, and the lower sole 100 has a button locking portion 150 on which the button rests. It is further provided, and the coupling hole 170 of the lower sole 100 is formed with an uneven portion 190 having a larger diameter to improve the fixing force by horizontal pressure of the coupling pin 300 and button 400. It can be.

The coupling pin 300 includes a coupling pin protrusion 310 formed with a relatively large diameter to correspond to the coupling pin engaging portion 250; A coupling pin engaging portion 330 extending vertically from the coupling pin protrusion 310 to a diameter corresponding to the coupling hole 170, 270; and a button coupling portion 350 having an open bottom so that the button 400 can be internally fitted into the coupling pin 300.

The button 400 includes a button protrusion 410 formed with a relatively large diameter to correspond to the button locking portion 150; a button insertion portion 430 extending vertically to a diameter corresponding to the button engaging portion 350; and a coupling pin pressing portion 450 for horizontally pressing the coupling pin 300 to expand its diameter to correspond to the concavo-convex portion 190.

Referring to FIG. 9, in another embodiment, the coupling pin engaging portion 330 is cut vertically in the area of the button engaging portion 350 to enable coupling with low pressure when engaging the coupling pin pressing portion 450. One or more slit portions 370 may be formed. At this time, when the coupling pin pressing portion 450 is inserted into the button coupling portion 350, the coupling pin coupling portion 330 is opened by the slit portion 370, thereby creating a gap, thereby preventing the coupling of the button 400. It has the advantage of becoming easier.

Hereinafter, a sole replaceable shoe according to another embodiment of the present invention will be described with reference to FIG. 10. Figure 10 is a simple illustration to explain an anti-slip member according to another embodiment of the present invention.

Referring to Figure 10, the sole replaceable shoe according to another embodiment of the present invention includes an anti-slip member 500 made of a ring-shaped elastic material coupled to the outer peripheral surface of the lower sole 100 to prevent slipping while the wearer is walking. ), wherein the lower sole 100 further includes an anti-slip groove 195 that can be fitted to the outer peripheral surface in a direction perpendicular to the length of the wearer's foot so that the anti-slip member 500 is coupled to the anti-slip member 500. The length along the outer peripheral surface of the anti-slip groove 195 is formed to be 80% to 85% of the length of the anti-slip member 500, and the width of the outer peripheral surface of the anti-slip groove 195 is 75% of the thickness of the anti-slip member 500. It can be formed from % to 80%. Since the anti-slip member 500 has elasticity, it can be stably fixed to the lower sole 100 when applied to the specifications in the above range, and the anti-slip member 500 does not separate even while the wearer is walking and has an anti-slip function. can be used efficiently. In particular, even within the above-described thickness range, the anti-slip member 500 is extended and joined to the lower sole 100, so not only can it be inserted and fixed into the anti-slip groove 195, but also the tensile force disappears again after coupling. As the thickness becomes thicker, it can protrude and be fixed beyond the anti-slip groove 195, which has the advantage of fully demonstrating the anti-slip effect.

The anti-slip member may include one or more materials of elastic rubber, elastic PVC, and elastic TPR. For example, the anti-slip member may include 55 to 65% by weight of elastic rubber, 25 to 35% by weight of elastic PVC, and 5% by weight of elastic TPR. It may contain from 15% by weight.
