Abstract
Description
- The present invention relates to a check valve plate for shoes, and more particularly, to a check valve plate for shoes, which suggests a structure in which valves are formed inside a porous valve plate having a predetermined thickness (t), and the lower portions of the valves do not protrude downwardly from the porous valve plate, such that the thickness of the porous valve plate having the valves formed therein can be minimized, and the porous valve plate can be easily applied to and used in shoes having thin soles, and thus versatility of a product can be guaranteed.
- As well known, shoes are means for protecting feet of a person who walks, and are typically manufactured by using leather or synthetic resin which is not breathable. Therefore, air circulation is not well performed in shoes. Accordingly, shoes may have a bad odor due to sweating or moisture and may cause diseases such as athlete's foot or eczema due to the propagation of germs,
- In order to solve these problems, shoes having an air-ventilation device installed therein have been developed in recent years. A typical structure of such air-ventilated shoes includes a pump which is installed inside a shoe sole, for drawing-in or discharging air, and an air suction pipe and an air discharge pipe, to which check valves connected with the pump are attached, and which are installed at the front or back of shoes, such that, when a user lands while walking, air inside the shoes is drawn into the pump through the air suction pipe by the pumping action of an elastic member installed in the pump, and is discharged to the outside through the air discharge pipe.
- However, in the case of the related-art air-ventilated shoes described above, since the air suction pipe is connected to a certain area of the front or back of the shoes, only the air in a specific area is drawn in or discharged. Therefore, there is a problem that the air distributed all over the shoes cannot efficiently circulated.
- As a prior art to solve the above-mentioned problems, there is disclosed Korean Patent Registration No. 10-1164463 (titled “Shoes Having Air Circulation Function”) (hereinafter, referred to as “prior art”), which was filed by the same applicant as the applicant of the present application on Jul. 12, 2010 and registered on Jul. 4, 2012,
- This prior art discloses shoes having an air circulation device installed therein, including: a sole which has a receiving groove formed on the center of the upper surface thereof, and has an air chamber, an air passage, and a passage part formed on the bottom of the receiving groove, for discharging air; an inner cushion which is inserted into the receiving groove of the sole to provide a high cushion force while a user is walking; an inclined adhesion protrusion which is formed along the outer circumference of the receiving groove of the sole and is inclined downwardly from the outside to the inside; a porous valve plate which is stacked on the upper surface of the inner cushion and has the outer circumferential surface of the lower end thereof brought into surface contact with the upper surface of the inclined adhesion protrusion, thereby forming a contraction and restoring space above the inclined adhesion protrusion; a plurality of valves which protrude downwardly from the porous valve plate, and are inserted into holes formed on the inner cushion and are selectively opened/closed according to contraction and restoring of the porous valve plate which is pressed by a midsole, and which discharge polluted air in the shoes to the air chamber of the sole; and the midsole and an insole which are stacked on the upper surface of the porous valve plate in sequence, wherein the midsole and the porous valve plate are greatly contracted and restored by weight transferred during the walking process through the contraction and restoring space, and thereby discharge the air inside the shoes to the outside.
- In the prior art as shown in
FIG. 1 , however, due to the downwardly protruding structure of the valves 3 on the porous valve plate 2, the thickness (T) of the porous valve plate 2 in which the valves 3 are formed increases and the thickness of the shoe sole 1 on which the porous valve plate 2 is installed is required to increase. Therefore, there are problems that it is difficult to apply the above-described prior art to shoes having thin soles 1, and versatility of a product is low. - Furthermore, due to the downwardly protruding structure of the valves 3 on the porous valve plate 2, a hole 4 a is formed to elastically support the porous valve plate 2 and simultaneously to allow the valves 3 to be inserted and fixed therein. Therefore, the thickness of the inner cushion, which supports the valves 3 so as to prevent the valves 3 from being brought into the lower surface of the sole 1 when the porous valve plate 2 is pressed, is inevitably required to increase, and thus, there is a problem that the sole 1 is required to have a large thickness.
- The present invention has been developed in order to solve the above-mentioned problems, and an object of the present invention is to provide a check valve plate for shoes, which suggests a structure in which valves are formed inside a porous valve plate having a predetermined thickness (t), and the lower portions of the valves do not protrude downwardly from the porous valve plate, such that the thickness of the porous valve plate having the valves formed therein can be minimized, and the porous valve plate can be easily applied to and used in shoes having thin soles, and thus versatility of a product can be guaranteed.
- Furthermore, another object of the present invention is to provide a check valve plate for shoes, which has a structure in which valves are not exposed under a porous valve plate, such that, even when an inner cushion for elastically supporting the porous valve plate has a small thickness, the valves can be prevented from being brought into contact with a sole as the porous valve plate is pressed and an opening/closing part can be stably prevented from being opened, and thus the porous valve plate can be easily applied to thin soles and versatility of a product can be guaranteed.
- In addition, another object of the present invention is to provide a check valve plate for shoes, which absorbs and removes an external force transferred to valves at tension grooves so as to prevent the valves formed in a porous valve plate from having their shapes deformed by the influence of the external force even when the porous valve plate is exposed to the external force and has its shape deformed, such that the valves can be guided to stably perform an opening/closing function.
- To achieve the above-stated objects of the present invention, a check valve plate for shoes according to the present invention includes: a porous valve plate which is stacked on the upper surface of a shoe sole having receiving grooves formed therein, and thereby closes the receiving grooves, and which has elasticity; and a plurality of valves which are formed inside the porous valve plate and are selectively opened/closed according to air pressure, and are formed so as not to deviate from a thickness (t) of the porous valve plate.
- The valves may be formed inside the porous valve plate having the predetermined thickness (t), and the lower portions of the valves may not protrude downwardly from the
porous valve plate 10, such that the thickness of the porous valve plate having the valves formed therein can be minimized and the porous valve plate can be easily applied to and used in shoes of soles having a small thickness. - In addition, the check valve plate for shoes may include: first annular tension grooves which are formed to be spaced apart from the circumferences of the valves toward the outside on the upper surface of the porous valve plate; second annular tension grooves which are formed to be spaced apart from the first tension grooves toward the outside on the lower surface of the porous valve plate; and annular locking protrusions which extend downwardly from the lower portion of the porous valve plate having the valves formed therein.
- When the porous valve plate is exposed to an external force, the external force transmitted to the valves may be absorbed and removed by the tension grooves, such that the valves formed in the porous valve plate are prevented from having their shapes deformed by the external force.
- The check valve plate for shoes may further include shape deformation prevention grooves which are formed along the outer circumference of the porous valve plate, and are formed on the upper surfaces of the circumferences of the valves.
- According to the present invention as described above, the check valve plate for shoes suggests the structure in which the valves are formed inside the porous valve plate having the predetermined thickness (t), and the lower portions of the valves do not protrude downwardly from the porous valve plate, such that the thickness of the porous valve plate having the valves formed therein can be minimized, and the porous valve plate can be easily applied to and used in shoes having thin soles, and thus versatility of a product can be guaranteed.
- Furthermore, the check valve plate for shoes absorbs and removes an external force transferred to the valves at the tension grooves so as to prevent the valves formed in the porous valve plate from having their shapes deformed by the influence of the external force even when the porous valve plate is exposed to the external force and has its shape deformed, such that the valves can stably perform an opening/closing function.
- Furthermore, the valves are not exposed under the porous valve plate, such that, even when an inner cushion for elastically supporting the porous valve plate has a small thickness, the valves can be prevented from being brought into contact with the sole as the porous valve plate is pressed and the opening/closing part can be stably prevented from being opened, and thus the porous valve plate can be easily applied to thin soles and versatility of a product can be guaranteed.

porous vale plate 10, which may occur during the process of fixing theporous valve plate 10 to the sole 1 and a midsole 7 by bonding, such that the valves 20 can be prevented from being widened and opened as theporous valve plate 10 is expanded and stretched, or a problem which may hinder the valves 20 formed in theporous valve plate 10 from being smoothly opened as theporous valve plate 10 contracts can be prevented in advance. - As shown in
FIG. 2 , the valves 20 are formed inside theporous valve plate 10 in plural number, and are selectively opened/closed according to air pressure and are formed so as not to deviate from the thickness (t) of theporous valve plate 10. - That is, the valves 20 are formed inside the
porous valve plate 10 having a predetermined thickness (t), and the lower portions of the valves 20 do not protrude downwardly from theporous valve plate 10. Therefore, compared to the thickness (T) of the porous valve plate 2 including the valves 3 in Korean Patent Registration No. 10-1164463 (titled “Shoes Having Air Circulation Function”), which was developed by the same applicant as the applicant of the present application, the thickness (t) of theporous valve plate 10 including the valves 20 can be greatly reduced, such that thecheck valve plate 100 for shoes of the present invention can be easily applied to and implemented in shoes having thin soles, and versatility of a product can be guaranteed. - As shown in
FIG. 2 , each of the valves 20 has predetermined elasticity and is formed in a hemispherical shape to have an upper end opened and have an empty space therein, and one or more opening/closing parts 21 are formed on the side surface of the valve 20 by cutting. - The
check valve plate 100 for shoes of the present invention, which includes the porous valve plate and the valve as described above, may be installed on the sole of the shoe. When a wearer walks, theporous valve plate 10 is pressed downwardly. In this case, the receiving grooves 1 a of the sole 1 are contracted and air pressure is generated therein as shown inFIG. 3A . The opening/closing part 21 of each of the valves 20 is pressed by the air pressure and is closed. Accordingly, the air in the receiving grooves 1 a flows into the check valve 6 through the passage part 6, and is discharged to the outside. - To the contrary, when the press to the
porous valve plate 10 is removed and theporous valve plate 10 is restored as shown inFIG. 3 b, the receiving grooves 1 a of the sole 1 expands. In this case, external air flows into the shoes due to an air suction force, which is generated in the process of expanding the receiving grooves 1 a, and flows to the upper portions of the valves 20 and flows into the receiving grooves 1 a through the opening/closing parts 21 of the valves 20. In this case, the opening/closing part 21 of each of the valves 20 is naturally widened and opened by the inflow of air pressure, such that air flows into the receiving grooves 1 a. - As shown in
FIG. 2 , theporous valve plate 10 may further include: a first annular tension groove 31 which is formed to be spaced apart from the circumference of each of the valves 20 toward the outside on the upper surface of theporous valve plate 10; and a second annular tension groove 32 which is formed to be spaced apart from the first tension groove 31 toward the outside on the lower surface of theporous valve plate 10. Therefore, the valves 20 are configured in the form of typical bellows. - That is, the
porous valve plate 10 is continuously pressed by the weight of a wearer while the wearer is walking. In this case, when a pressing force is transferred to the valves 20 formed in theporous valve plate 10, and the opening/closingpart 21 of each of the valves 20 has its shape deformed and is opened, air is not smoothly circulated in the shoes. Accordingly, as shown inFIG. 3A , the tension grooves 31 and 32 formed on the outside of the valves 20 in the form of typical bellows receive the transferred force, and are induced to have their shapes deformed, such that the force transferred to the tension grooves 31 and 32 is naturally removed and thus the valves 20 is not influenced by the external force. - As shown in
FIG. 2 , thecheck valve plate 100 may further include annular locking protrusions 33 which are formed on the lower portion of theporous valve plate 10 in which the valves 20 are formed, for being inserted into holes 4 a of the inner cushion 4. - The locking protrusions 33 guide the valves 20 to be securely fixed in place to fluidly communicate with the holes 4 a of the inner cushion 4 during the process in which the
porous valve plate 10 expands and is restored, and, as shown inFIG. 3A , the locking protrusions 33 guide external air to flow into the holes 4 a of the inner cushion 4 through the valves 20 and to be stably transferred to the receiving grooves 1 a of the sole 1. - When the
porous valve plate 10 is pressed and descends and is brought into contact with the sole 1, the locking protrusions 33 support the valves 20 and guide to prevent the opening/closingpart 21 of each of the valves 20 from having its shape deformed and being opened. - Herein, in Korean Patent Registration No. 10-1164463 (titled “Shoes Having Air Circulation Function”) developed before by the same applicant as the applicant of the present application, the inner cushion 4 for supporting the porous valve plate 2 is manufactured to have a large thickness in order to prevent the valves 3 protruding downwardly from the porous valve plate 2 from being brought into contact with the sole 1. However, in the
check valve plate 100 for shoes of the present invention, the valves 20 do not protrude downwardly from theporous valve plate 10, such that thecheck valve plate 100 can be manufactured to have a small thickness and can be easily applied to shoes having thin soles. - The
check valve plate 100 for shoes of the present invention configured as described above suggests the structure in which the valves 20 are formed inside theporous valve plate 10 having the predetermined thickness (t), and the lower portions of the valves 20 do not protrude downwardly from theporous valve plate 10, such that the thickness of theporous valve plate 10 having the valves 20 formed therein can be minimized, and the constitution (feature) of thecheck valve plate 100 for shoes of the present invention can be easily applied to and used in shoes having thin soles, and thus versatility of a product can be guaranteed. - Furthermore, the
check valve plate 100 for shoes has the structure in which the valves 20 are not exposed under theporous valve plate 10, such that, even when the inner cushion 40 for elastically supporting theporous valve plate 10 is formed to have a small thickness, the valves 20 can be prevented from being brought into contact with the sole 1 as theporous valve plate 10 is pressed, and the opening/closingpart 21 can be stably prevented from being opened, and thus thecheck valve plate 100 can be easily applied to shoes having thin soles and versatility of a product can be guaranteed. - In addition, the
check valve plate 100 for shoes absorbs and removes an external force transferred to the valves 20 at the tension grooves 31 and 32, which are formed in the form of bellows, so as to prevent the valves 20 formed in theporous valve plate 10 from having their shapes deformed by the influence of the external force even when theporous valve plate 10 is exposed to the external force and has its shape deformed, such that the valves 20 are guided to stably perform an opening/closing function. - The
check valve plate 100 for shoes having the above-described constitution according to an exemplary embodiment of the present invention is installed on the shoe sole 1 and continuously circulates air as follows. - First, when the
porous valve plate 10 is pressed downwardly and is expanded by the weight of a walker during the walk as shown inFIG. 3A , the inner spaces of the receiving grooves 1 a of the sole 1 are contracted and air pressure is generated therein. Since the opening/closingpart 21 of each of the valves 20 is pressed and closed by the air pressure, the air in the receiving grooves 1 a flows into the check valve 6 through the passage part 5 and thus is discharged to the outside. - Thereafter, when the press is removed and the
porous valve plate 10 is restored as shown inFIG. 3B , the inner spaces of the receiving grooves 1 a of the sole 1 expand, and external air flows into the shoes due to an air suction force, which is generated during the process in which the inner spaces of the receiving grooves 1 a expand, flows to the upper portions of the valves 20, and then flows into the receiving grooves 1 a through the opening/closing parts 21 of the valves 20. In this case, the opening/closing parts 21 of the valves 20 are naturally widened and opened by the inflow of air pressure, such that the air flows into the receiving grooves 1 a. - Accordingly, the
porous valve plate 10 is continuously expanded and restored by the weight of the walker during the walk, and air in the shoes is discharged to the outside and external air flows into the shoes as much as discharged air, such that ventilation can be smoothly performed in the shoes. - While the invention has been described with reference to certain preferred embodiments illustrated in the drawings, the embodiments are merely examples and are not limited to the above-described embodiments, and it will be understood by those skilled in the art that various changes can be made and other equivalent embodiments can be provided based on the descriptions provided herein. In addition, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention. Therefore, the scope of the invention is defined not by the detailed description of the invention but by the appended claims and the technical idea thereof.
