Abstract

The present invention relates to a functional shoe and, more particularly, to a shoe having a sole and a body which are freely separated and coupled so as to have a function of changing a color thereof according to wear of the sole of the shoe and a fashion and a shape thereof according to a function. The present invention provides the functional shoe in which an interval between the body and the sole of the shoe is not widened and the body and the sole of the shoe are also easily coupled, using a coupling structure of the surface of the body of the shoe coupled to the sole of the shoe.

Description

TECHNICAL FIELD

The present invention relates to a shoe for enabling a sole to be easily separated and coupled, and more particularly, to a functional shoe including a replaceable sole, which is capable of changing a functionality thereof because the sole of the shoe is easily replaced and replacing the sole of the shoe when worn so as to continuously maintain the function thereof.

BACKGROUND ART

In general, a shoe is classified by a function thereof. Especially, a function of a shoe is expressed according to a sole of the shoe and, as time elapses, a surface of the shoe is torn out or the sole is worn to replace the shoe by a new product. Lifetime and function of the shoe are determined by especially a shape or wear of the sole of the shoe, thereby replacing the shoe by the new product.
The function and usage of a current shoe are variously varied by the sole contacting the ground, and the shoe is generally replaced because a surface contacting the ground is worn. Hereinafter, various structures for replacing the sole will be described.
First, in the Patent Application No. 10-2012-0044579, as a sole of a shoe is replaced by using an insertion groove and an insertion slot respectively disposed in a front side and a rear side of the sole of the shoe. Since a bolt and a nut are used to connect them, the sole of the shoe increases in height to cause discomfort while walking. Further, replacing the sole of the shoe is difficult.
Also, in the Patent Application No. 10-2012-0030783, a shoe itself needs to be assembled. Since the sole itself includes too many components, the components need to be assembled instead of simple replacement. That is, the replacement and detachment/attachment are difficult.
Also, in the Patent Application No. 10-2009-0109622, a structure in which a main body and a sole of a shoe are coupled by using a protrusion having an uneven structure, which seems to be similar to that of the present invention. However, when the shoe is made by the present invention, although the main body and the sole of the shoe seem to be well fitted to each other, an interval may occur between the main body and the sole of the shoe while moving, and foreign substances such as a stone may be inserted into the interval to make a visually poor appearance and cause a serious problem while moving.
That is, when the related arts are put together and considered, regardless of the kinds of a shoe, since the sole contacting the ground is worn the most, the lifetime of the shoe is generally determined on the basis of a degree of wear of the sole.
Accordingly, although product lifetime is maintained because the rest portion excluding the sole is not worn, only the sole of the shoe is worn to replace the entire shoe, thereby causing an economic burden and also environmental pollution including waste of resources. Also, when characteristics of the shoe are closely checked, the shoe is often named after the sole thereof. In case of golf shoe, for example, since an object called a spike or a stud of a golf shoe is attached to the sole of the shoe to name the shoe as the golf shoe, a function using the characteristics of this sole may be added to be realized separately by sole.
Thus, the present invention is provided to solve the above-described conventional problems.

DISCLOSURE OF THE INVENTION

Technical Problem

Accordingly, to solve the above-described limitations, the purpose of the present invention is to provide a shoe for enabling a sole of a shoe to be easily separated and coupled, in which the sole of the shoe is capable of being easily separated and coupled and further a coupled portion is not separated while moving not to interrupt any kind of movement.

Technical Solution

To solve the above-described purpose, the present invention, so as to enable a sole of a shoe to be easily separated and coupled, may provide an attaching/detaching unit on the sole of the shoe with various structures. For example, the present invention may be realized through a structure in w a snap button is attached to a main body and the sole of the shoeto couple or separate the main body and the sole of the shoe to/from each other, a structure in which a protrusion including a body and a head in a hook method is inserted into a hole and pushed back and forthto couple or separate the main body and the sole of the shoe to/from each other, and a structure in which a Velcro that is easily purchased is used to couple or separate the main body and the sole of the shoe to/from each other. Also, the above-described specific structures for attaching/detaching may be mixed together to be used.
In the structure using the snap button of the above-described attaching/detaching units, a snap button female is installed to a main body of a shoe and a snap button male is installed to a sole of the shoe, thereby being matched and coupled to each other.
Also, in the hook structure, a circular shaped (or possibly another shaped) head portion and a circular shaped hole corresponding thereto may be provided. Since one side is greater than the head portion and thus, through the side, the head portion is inserted and pushed to be coupled or separated in a reverse method.
Also, in the Velcro structure using a conventional Velcro, a Velcro female may be installed to a main body of a shoe and a Velcro male may be installed to a sole of the shoe to couple/separate the main body of the shoe to/from the sole of the shoe. Here, in consideration of a thickness of the Velcro, a groove may be defined in a portion in which the Velcro is disposed to prevent an interval between the main body and the sole of the shoe from occurring.
Also, in the valley type coupling structure, valleys that contact each other and respectively disposed on a sole and a main body of a shoe may be provided to be coupled by contacting each other and pressing. Here, coupling and separation between the sole and the main body of the sole may be easy and convenient.

Advantageous Effects

The present invention relates to the shoe for enabling the sole of the shoe to be easily coupled or separated. According to the present invention, the present invention also provides the functional shoe for replacing the sole to fit to the function of the shoe and also easily replacing the sole that is worn due to wear to thereby solve three limitations including the function, the wear, and the fashion
Thus, the present invention provides an effect in which costs for purchasing shoe due to wear of the sole of the shoe is reduced, expenses for purchasing shoe for other purpose due to a functional aspect of the shoe is reduced, and the shoe are renewed by replacing only the sole of old shoe.

MODE FOR CARRYING OUT THE INVENTION

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the same or similar components in the drawings are designated by the same reference numerals as far as possible even if they are shown in different drawings. Also, in the following description, specific details such as concrete process flow are described to provide more general understandings of the present invention.
The present invention provides a functional shoe, in which a sole of the shoe is coupled and separated by using a coupling structure. Here, the coupling structure is prevented from being separated while moving with wearing the shoe. An attaching/detaching unit for coupling and separating the sole of the shoe may be variously provided to be selectively provided to shoe fitted to each of functions and additionally replace only the sole of the shoe, which is relatively more worn than other portions of the shoe.
FIG. 1 is a basic configuration view illustrating shoe including a replaceable sole according to the present invention.
This structure, in which the attaching/detaching unit is a general button, is an extremely simple structure for manufacturing shoe in such a manner that a button is attached to a main body of shoe to connect the sole.
FIG. 2 illustrates that a snap button structure, which is usually used in general clothing or bags, is improved so that a snap button is attached to a main body and a sole of shoe. When manufactured as described above, there are a limitation in which coupling time is delayed due to the many number of coupling and, on the other hand, an advantage in which separation time for is reduced.
FIG. 3 illustrates a hook structure in which a groove 301 is defined in a sole of shoe and the interval is coupled by using a head protrusion 302 and a body protrusion 303.
This structure has an advantage in which the coupling and separation are easy and also, when once coupled, the sole of the shoe is not separated while moving.
FIG. 4 illustrates a Velcro structure in which a Velcro female 401 and a Velcro male 402 are engaged to be coupled to and separated from each other. Here, due to a thickness of the Velcro, although an interval may be widened therebetween, the interval may be removed by defining a groove having a thickness corresponding thereto at a position in which a sole 1000 or a main body 2000 of shoe is engaged.
FIG. 5, which helps to understand an operation principle of a hook of the hook structure, illustrates that a head protrusion 302 is inserted into a head protrusion insertion groove 304 to push and couple a body protrusion 303 to a body protrusion joining groove 305.
Although the shoe in FIGS. 1, 2, 3, 4, and 5 are assumed to have a heel, FIG. 6 illustrates a constitution in which a sole 1000 and a main body 2001 of shoe are separable from each other even for shoe without the heel.
FIG. 7 illustrates that, to replace only a heel instead of an entire sole of shoe,
only the heel of the shoe is replaced in the structures of FIGS. 1, 2, 3, and 4. This also may reduce costs for purchasing shoe due to wear of the heel of the shoe and further add a functional element to the heel to add a function. In addition, a design function capable of applying a color to the heel to differentiate only the color of the heel may be performed.
FIG. 8 illustrates a structure of coupling of shoe in a different way, in which a valley 1001 of a sole of shoe and a valley 2001 of a main body of shoe are provided and the valley 1001 of the sole of the shoe and the valley 2001 of the main body of the shoe contact each other and are pressed to be coupled.
Hereinafter, a structure for embodying the present invention will be described.
FIG. 1 illustrates a structure in which a sole 1000 of shoe, a main body 2000 of the shoe, a hole 102 disposed in the sole, and a button 101 are provided and, when coupled, the hole 102 and the button 101 are engaged to be coupled. When the structure is manufactured by the present structure, time and period may be remarkably reduced and also have excellent usability.
Also, positions of the button and the groove of the sole and main body of the shoe may be exchanged with each other. Here, the positions of the groove and the button may be defined to be alternately installed.
FIG. 2 illustrates a structure in which the sole 1000 of the shoe, the main body 2000 of the shoe, a snap button male 201 on the sole of the shoe, and a snap button female 202 are provided, and, when the shoe are coupled, the snap button male 201 and the snap button female 201 are engaged to be coupled. When the structure is manufactured by the present structure, time and period may be remarkably reduced and also the coupling and separation may be easily performed.
Alternatively, positions of the snap button male and the snap button female of the sole and the main body of the shoe may be exchanged with each other. Here, the positions of the snap button female and the snap button male may be defined to be alternately installed.
FIG. 3 illustrates a constitution that is constituted by the shoe sole 1000 including the groove 301, the head protrusion 302, and body protrusion 301, and the shoe main body 2000, in which the groove 301 has one end having a size 305 corresponding to the body protrusion and the other end having a size 304 corresponding to the head protrusion so that the head protrusion 302 is inserted into the head protrusion insertion groove 304 and pushed toward the body protrusion to couple the body protrusion 303 to the body protrusion joining groove 305. Here, the structure has an advantage in which the coupling and separation are easily performed and also, once coupled, the sole of the shoe is never separated while moving.
FIG. 4 illustrates a structure that is capable of coupling and separating by using a Velcro, in which a Velcro female 401 is attached to a sole 1000 of a shoe and a Velcro male 402 is provided on a main body 2000 of the shoe to perform the coupling of the shoe.
Here, since an interval may occur between the sole and the main body of the shoe due to the thickness of the Velcro, a groove having a thickness corresponding to the thickness of the Velcro is defined in the sole and the main body of the shoe.
FIG. 5, which helps to understand an operation principle of a hook in a hook structure,
illustrates a head protrusion 302 is inserted into a head protrusion insertion groove 304 to push and couple the body protrusion 303 to the body protrusion joining groove 305.
The hook of the hook structure includes a hook groove 301 and a hook fastener 306. The hook fastener is inserted through the head protrusion insertion groove 304 of the hook groove and pushed toward the body protrusion joining groove 305 for fastening.
Although the shoe in FIGS. 1, 2, 3, 4, and 5 are assumed to have a heel, FIG. 6 illustrates a constitution in which a sole 1000 of a shoe is separable from a main body 2001 of the shoe even for a shoe without the heel.
FIG. 7 is an exemplary view illustrating a structure for replacing only a heel instead of an entire sole in case of shoe having the heel. As the structure for replacing only the heel instead of the entire sole, FIG. 7-1 illustrates a structure for coupling and separating using a general button, FIG. 7-2 illustrates a structure for coupling and replacing only the heel of the shoe using a snap button, FIG. 7-3 illustrates a structure for coupling and separating the heel of the hook structure, and FIG. 7-4 illustrates a structure for separating and coupling in the Velcro structure.
FIG. 8 illustrates, as a structure for coupling shoe in a different manner, a structure that is easily coupled and separated, in which a valley 1001 of a sole of a shoe and a valley 2001 of a main body of the shoe are provided and the valley 1001 of the sole of the shoe and the valley 2001 of the main body of the shoe may contact each other and be pressed to be coupled, and, in a reverse manner, the sole 1001 or 1000 and the main body 2001 or 2000 of the shoe may be separated from each other when a force is applied in directions different from each other.
Although the button 101, the snap button 201 and 202, the groove 301, the body 302, and head protrusion 303, the Velcro 401 and 402, the valley 1001 of the sole, and the valley 2001 of the main body of the shoe are constant in number in FIGS. 1, 2, 3, 4, 7, and 8, it is apparently understood to the skilled in the art that the number thereof may be variously varied.
The description of the present invention is intended to be illustrative, and those with ordinary skill in the technical field of the present invention pertains will be understood that the present invention may be embodied and modified in other specific forms without departing from the technical idea or essential features.
