Description

Technical Field

[0001] The present invention relates to an air-conditioning shoe that exhausts air to the feet (wearing feet) with shoes on by means of an exhaust mechanism of a built-in air-conditioning fan. It includes all of a cooling shoe that cools the wearing feet by blowing air, a warming shoe that keeps warm by warm air, and a cooling shoe that cools by cold air through heat exchange. Further, as shoes provided with the exhaust mechanism, in addition to work shoes such as safety shoes, it relates to sports shoes such as hiking boots and jogging shoes, or general shoes such as boots.

Background Art

[0002] Conventionally, shoes provided with a blower inside to impart an air-conditioning function have been disclosed. For example, as an air-conditioning shoe, there is disclosed one provided with a blower 27 that blows air in an air circulation path 101 into a shoe internal space 11d, a Peltier element 34 that transfers heat to the air blown by the blower 27, and a heater 39 (see Patent Document 1). It is said that control means 29a controls the operation and stop of the blower 27, the Peltier element 34, and the heater 39 so that the shoe internal temperature T1 detected by the temperature sensor 30 maintains the set temperature TS.

[0003] Also, there is disclosed one that forms a space in an L shape in a side sectional view from the back surface to the bottom surface of the heel portion of the footwear, provides an intake hole on the back surface, and has a rotary blower in the space at the bottom of the heel (see Patent Document 2). In this footwear, when the switch is turned on to drive the blower (12), the outside air sucked from the intake hole passes through the communication path (8) → air chamber (6) → ventilation path (7) → ventilation holes (11)(11) ··· and is introduced into the shoe interior <4), and the shoe interior (4) is constantly exposed to fresh outside air.

Patent Document 1

Patent Document 2

[0006] However, the air-conditioned shoes described in Patent Document 1 above use a system that takes in outside air only through intake holes on the back of the sole plate and blows it out through a horizontal path connected to these holes using a nearby vertical blower. As a result, the efficiency of outside air intake is limited by using only the back holes and horizontal path. Furthermore, if the sole plate is compressed or twisted due to long-term use of the shoes, causing deformation of the intake holes and horizontal path, outside air intake becomes impossible.

[0007] Furthermore, the footwear described in Patent Document 2 above takes in outside air through intake holes arranged in a vertical row within the space inside the heel back plate. However, since the airflow path is limited to the L-shaped space in the side cross-section extending from the inside of the heel back plate to the inside of the sole plate, there is a problem in that the airflow path becomes impossible if the airflow path is deformed due to compression or twisting of the heel back plate or sole plate due to long-term use of the shoes.

[0008] Furthermore, as seen in the aforementioned literature, conventional shoes equipped with air blowers either embed the rotary air blower directly into the sole plate or place it directly in the space within the bottom plate. As a result, when the vertical-axis rotary air blower located within the sole plate deforms due to compression of the sole plate, the air blower is easily subjected to mechanical limitations, leading to problems with the durability of the air intake and supply mechanism.

[0009] Therefore, the object of the present invention is to provide air-conditioned shoes that improve the efficiency of outside air intake, ensure a flow path even after prolonged use of the shoes, thereby enabling continuous intake of outside air, and that allow the intake and supply mechanism of the blower housed inside to continuously perform its function. [Means for solving the problem]

[0010] To address the above issues, the following solutions have been implemented. Note that the strings of numbers or combinations of numbers and letters following each term are reference symbols conveniently added to indicate the corresponding parts of each configuration shown in the figures as examples of embodiments, and do not in themselves limit the concept or scope of each configuration.

[0011] [1] The air-conditioned shoes of the present invention are A sole plate (1) has a box-shaped hole (100) in the heel portion, and multiple flow channel grooves (110, 120, 130) extending from the box-shaped hole 100 to the front sole portion, provided on the upper surface of the plate. A box-shaped fan (2) is provided within the box-shaped enclosure, comprising a flat box-shaped housing housed in the aforementioned box-shaped hole 100, and an intake / exhaust mechanism 2F that draws in air from at least one side 23 of the housing and blows air forward from the front 22 of the housing. A counter heel (4) is erected on the upper part of the sole plate (1) at the rear of the heel portion, and consists of a curved plate body that integrally surrounds the rear of the heel portion and the surrounding sides, with multiple convex ridges (42, 43) formed integrally on the outer surface of the curved plate body that extend horizontally or diagonally downward. A heel cover (5) of the curved plate body is erected to cover the outer circumference of the curved plate body of the counter heel (4), and surrounds the outer shape of the curved plate body of the counter heel and the protruding tip of the protrusion, and constitutes the rear part of the heel portion and the surrounding side circumferences, Air-conditioned shoes comprising at least the following: The heel cover (5) is the end or surface of a curved plate body, and a plurality of small openings (5M) for taking in outside air are provided in a range that integrally encloses the area from the rear of the heel to the surrounding sides, arranged in the lateral and vertical directions. The outer edges of the heel cover (5) and the counter heel (4) are enclosed and sealed with shoe fabric and sole plate. Between this sealed heel cover (5) and the counter heel (4), Convex A partitioned air passage is formed, This air passage is characterized by communicating with the small opening (5M) and with the space on the side of the box-shaped hole (the space near the side of the housing of the box-shaped fan 2 housed in the box-shaped hole).

[0012] With this structure, a continuous space that serves as an air passage is secured between the sealed heel cover (5) and the counter heel (4), extending in three directions circumferentially from the rear of the heel to both sides. The sides of this continuous space can take in outside air through numerous small openings (5M) formed circumferentially, and the lower part of this continuous space communicates with the space on the side of the box-shaped hole, thereby securing an air passage in the direction of the heel side. As a result, even if the heel plate deforms due to long-term use, a flow path for taking in outside air is secured, allowing the intake and supply mechanism to continue to perform and obtain a sufficient air supply effect. Furthermore, by providing a box-shaped opening in the sole plate to serve as a housing space for a box-shaped enclosure, and housing a box-shaped fan covered by the box-shaped enclosure inside, the durability of the fan is improved, and the fan's suction and blowing function can be maintained even when the sole plate is compressed or twisted.

[0013] The upper edge of the heel cover (5) is molded to follow the curved upper edge of the counter heel (4), and the heel cover (5) and the counter heel (4) are combined and their upper and lower edges are sealed, forming the inner and outer surfaces of the heel portion of the air-conditioned shoe, as well as creating a structure for the airflow channel of the taken-in air.

[0014] In this embodiment, the small opening 5M of the heel cover (5) consists of a mesh opening divided in a polygonal direction and arranged in a predetermined configuration. Other forms of the small opening may include a slit-shaped opening divided by parallel bars, or an elongated rectangular opening.

[0015] In this embodiment, the multiple protrusions consist of curved ridges that extend diagonally downward from the center of the back of the counter heel toward both sides. Specifically, they consist of three central protrusions 42 that extend horizontally along the back of the counter heel, and four lateral protrusions 43 that extend diagonally forward and downward along the sides of the heel cover, with a small gap between them (Figures 2, 6, and 7).

[0016] [2] In the air-conditioned shoes of the present invention, Of the box-shaped holes formed in the sole plate (1), an enlarged hole 124 is provided on the side corresponding to at least one of the housing sides 23 of the box-shaped fan 2, by enlarging the upper and / or side portions of the box-shaped hole 100. The outer surfaces of both ends of the curved plate body of the counter heel (4) are formed such that the protrusions (42, 43) extend diagonally downward, and the ends of the extended protrusions are oriented toward the opening of the enlarged hole 124 or penetrate into the hole. The air drawn in through the small opening in the heel cover 5 is introduced into the enlarged hole 124 through the airflow passage between the heel cover (5) and the counter heel (4), and is drawn in by at least one side of the housing 23 of the box-shaped fan 2.

[0017] In this embodiment, the enlarged hole 124 is formed as a U-shaped notch in plan view that widens the box-shaped hole 100 over a predetermined length in front of the side of the box-shaped hole 100, and multiple upright columns 124 are formed to protrude from the side of the notch so as to divide the direction of the predetermined length of the notch shape (Figure 3). Each of the multiple upright columns 124 is formed at a position corresponding to the end of a diagonally downward protrusion formed on the counter heel 4, and as the end of each protrusion abuts against each of the multiple upright columns 124, each flow path partitioned by the multiple protrusions is re-partitioned by the multiple upright columns 124 of the enlarged hole 124 and opened to the box-shaped hole 100 (Figures 3 and 4).

[0018] The inhaled air is exhausted forward by the operation of the box-shaped fan, and is blown face-to-face upward inside the shoe from the ventilation openings (310M, 320M, 330M) of the sole sheet through the flow path groove in front of the sole plate. Thereby, an effective air-conditioning function inside the air-conditioned shoe is achieved.

[0019] Also in the embodiment, the heel upper-6HC constituting the upper part of the heel structure is sewn in a sealed state along the curved upper side of the heel cover. The heel upper-6HC is composed of a front cloth, a back cloth, and an interference material filled between them, and its lower edge is formed by closely adhering the front cloth and the back cloth along the shape of the curved upper side of the heel cover, and further reinforcing with a line-shaped resin material to form a line reinforcement part. This line reinforcement part closely adheres and seals the curved upper side of the counter heel and the upper side of the heel upper having a shape along this upper side, and frames the structure of the flow path composed of the counter heel and the heel cover.

[0020] 〔3〕In the air-conditioned shoe of the present invention, The counter heel (4) is composed of an elastic flat plate having a mountain-shaped upper side that is symmetric about the left and right. It is vertically arranged on the inner circumference of the heel part of the sole plate in a state where it is bent by applying a bending stress to this elastic flat plate. The heel cover (5) is composed of a three-dimensional molded body in a deformed spherical shape, which is three-dimensionally molded with an outer shape along the curved shape of the elastic flat plate in the curved state of the counter heel (4) and an inner surface shape along the tip shape of the convex strip. This three-dimensional molded body is fixed to the outer circumference of the heel part of the sole plate in a state of being elastically contacted with the outer surface of the vertically arranged counter heel. Characterized in that a thick three-dimensional heel part is formed by closely fixing the counter heel and the heel cover in a state of overlapping the inner and outer surfaces to the heel part of the sole plate.

[0021] This three-dimensional heel part has a counter heel (4) having an internal stress of elastic reaction due to bending stress as an internal structure, and a heel cover of a three-dimensional molded body surrounding the counter heel (4) in a state where a bending stress is applied thereto as an external structure.

[0022] Furthermore, the heel cover (5) has a mesh-like small opening 5M formed by a wire grid within the surface of the deformed spherical shape, excluding the periphery of the three-dimensional molded material, with honeycomb-shaped small holes arranged within it. This mesh-like small opening 5M on the heel cover is exposed to the outside of the air-conditioned shoe, giving it a distinctive appearance as part of the heel design.

[0023] [4] In the air-conditioned shoes of the present invention, The heel cover (5) has a curved horizontal edge for most of its length, except for the tip of the lower edge of the three-dimensional molded material, and the variable tips on both sides of the three-dimensional molded material are formed into protruding pieces 5E that partially protrude downward from the horizontal edge. The protruding pieces 5E at both ends of this heel cover are fitted into fixing holes 125 provided in the front of the enlarged hole 124 in the sole plate and are glued in place. The heel cover 5 also has a mesh-like small opening 5M within the plane of the deformed spherical surface, excluding the periphery, in which honeycomb-shaped holes are arranged by a wire grid. The heel cover 5 is also firmly bonded and fixed by embedding the protruding pieces (5E) at the lower ends of both sides of the plate into the holes of the enlarged hole 124 in the sole sheet (3) or into fixing holes near the front of the hole.

[0024] [5] In the air-conditioned shoes of the present invention, The outer edge of the upper part of the sole plate (1) has a raised portion formed around it that conforms to the shape of a foot. A sole sheet (3), which is a foot-shaped sheet body that follows the rising portion, is sewn or glued to the upper surface of the sole plate (1) to cover the entire sole plate surface as the bottom surface of the shoe. This sole sheet is characterized by having ventilation openings (310M, 320M, 330M) (with mesh) formed in the front portion corresponding to the planar position of the aforementioned flow channel grooves (110, 120, 130).

[0025] The multiple flow channel grooves (110, 120, 130) of the sole plate (1) are, Multiple vertical channel grooves (110, 120, 130) run parallel to each other from the front of the box-shaped hole towards the toes, These multiple vertical channel grooves are interconnected in the width direction at multiple points along the vertical grooves, and multiple horizontal channel grooves (140, 150, 160) are also provided. It is formed from a tip channel groove (170) that brings together all of the multiple vertical flow channels (110, 120, 130) in a curved line that follows the shape of the toe, The sole sheet is characterized in that the opening edge is formed in a manner corresponding to the positions of the longitudinal flow groove, the transverse flow groove, and the tip flow groove (170).

[0026] The aforementioned protrusions of the counter heel are composed of multiple rows of diagonal protrusions (43) extending diagonally downward on the side surface and horizontal protrusions (42) extending horizontally at the same height on the heel portion, which are intermittently connected via vertically intermittent regions. On the inner surface of the enlarged hole 124, vertical grooves are formed between each of the multiple protruding vertical columns. These vertical columns are formed at positions corresponding to the extended ends of the oblique protrusions.

[0027] (6) The box-shaped fan is characterized in that a buffer plate of a predetermined thickness is provided on the top surface of the box-shaped housing, and the total height of the box-shaped fan, including the buffer plate, is housed in the box-shaped hole.

[0028] The three-dimensionally molded heel section, constructed in this manner, consists of a heel cover 5 that is relatively resistant to deformation and receives most of the external force, and a counter heel 4 that is easily elastically deformed by a three-dimensional curved material in the shape of an elastic plate. As a result, it is resistant to deformation even with use and ensures an internal airflow passage. In other words, the above combination configuration allows the heel section to easily take in outside air and stably introduce outside air into the box-shaped fan inside the sole plate, fulfilling an outside air intake function, and this function can be maintained unchanged even after long-term use. [Effects of the Invention]

[0029] By employing the above methods, the elastic recovery force of the heel structure itself can be relatively maintained even when deformed by repeated weight-bearing on the heel, providing a heel structure that can repeatedly and independently return to its original shape. Furthermore, it provides a heel structure that maintains durability even when repeatedly deformed and is resistant to breakage. [Brief explanation of the drawing]

[0031] Hereinafter, examples of embodiments for carrying out the present invention will be described with reference to Figures 1 to 7.

[0032] The air-conditioned shoes of the present invention consist of the following basic components. A sole plate (1) integrally molded with a shape that includes a housing hole for a box-shaped fan and multiple flow channel grooves connected thereto on its upper surface, A box-shaped fan (2) is enclosed in a flat, box-shaped casing, has a vertically rotating fan inside, has intake sections on both sides of the box-shaped casing, and has a blower section on the front for forward airflow. A thin, panel-shaped enclosure connected by a wire to a box-shaped fan, comprising a charging control panel (26) for operating and charging the box-shaped fan, The sole sheet (3) consists of a foot-shaped sheet with a partial opening that covers and fixes the top surface of the sole plate housing the box-shaped fan, and the periphery of the foot shape in plan view is sealed. The counter heel (4) consists of an elastic flat plate with a curved upper edge erected on the sole plate, and has multiple horizontal and diagonally downward convex ridges formed on the outer surface of the plate. A heel cover (5) is erected and fixed on the sole plate so as to surround and overlap the entire outer circumference of the counter heel, with an internal space open, and consists of a three-dimensional curved plate formed slightly larger than the upper edge of the counter heel. The shoe upper (6) is constructed to cover the foot by securing the sole sheet and overlapping the counter heel and heel cover to form a sole plate, with the area around the sole plate and above it being reinforced and made of fabric. An insole (7) having evenly spaced dot holes in the front half of the foot shape, It is composed of.

[0033] (Sole plate (1)) The sole plate (1) is provided with a box-shaped hole (100) in the heel section, and a number of flow channel grooves (110, 120, 130) that extend from this box-shaped hole to the front of the sole section.

[0034] (Flow channel groove) The predetermined flow path for the exhaust air is formed from vertical flow grooves (110, 120, 130) that run from the front of the box-shaped hole towards the toes, horizontal flow grooves (140, 150, 160) that connect these flow grooves in the width direction of the toes, and a tip-end flow groove (170) that brings together the multiple vertical flow passages along the shape of the toes.

[0035] (Enlarged hole 124) On both sides of the heel portion of the sole plate (1), enlarged holes 124 are provided, which are connected to each side of the box-shaped hole 100, thereby widening the width of the box-shaped hole over a certain range. In this embodiment, the enlarged hole 124 is formed as a U-shaped notch in plan view that widens the box-shaped hole 100 over a predetermined length in front of the side of the box-shaped hole 100, and multiple upright columns 124 are formed to protrude from the side of the notch so as to divide the direction of the predetermined length of the notch shape (Figure 3). Each of the multiple upright columns 124 is formed at a position corresponding to the end of a diagonally downward protrusion formed on the counter heel 4, and as the end of each protrusion abuts against each of the multiple upright columns 124, each flow path partitioned by the multiple protrusions is re-partitioned by the multiple upright columns 124 of the enlarged hole 124 and opened to the box-shaped hole 100 (Figures 3 and 4).

[0036] (Blow channel) The intake air is expelled forward by the operation of a box-shaped fan and blown upwards into the shoe through the airflow grooves at the front of the sole plate and through the ventilation openings (310M, 320M, 330M) of the sole sheet. This provides effective air conditioning inside the shoe.

[0037] (Box-type fan (2)) The box-shaped fan (2) is housed in a box-shaped enclosure, and includes an intake and exhaust mechanism that draws in air through slit holes on the sides 23 of the enclosure and blows air forward through air outlets on the front 24 of the enclosure. The box-shaped fan (2) is housed in a box-shaped enclosure of the sole plate 1, which is integrally molded from elastic resin, thereby covering the box-shaped enclosure with a so-called cushioning material and providing double protection for the intake and exhaust mechanism. Furthermore, because it is designed to be inserted and fitted into the box-shaped enclosure, it is possible to remove the box-shaped fan once it has been housed by exposing the sole plate, and it is also possible to replace the box-shaped enclosure itself, or parts such as the rotating fins or rechargeable battery.

[0038] The box-shaped fan 2 is cased as a rigid body by a box-shaped housing that has reinforcing columns and braces inside. The rechargeable battery and terminals are housed towards the rear of this box-shaped housing, and the blade-shaped rotating fins are housed towards the front so as to be able to rotate in a perfect circle when viewed from above (Figure 3). A buffer plate 24 of a predetermined thickness, approximately 20% of the thickness of the box-shaped housing, is provided on the top surface of the box-shaped housing. The rotating fins 2F blow air towards the front of the box-shaped housing as they rotate around a vertical axis. The vertical axis is supported at its upper and lower ends within the housing of the box-shaped housing via a clearance space, and the vertical axis and the fins attached to its outer circumference are made of elastic resin, making them less susceptible to vibrations of the box-shaped housing and compression deformation of the housing itself.

[0039] (Charging control panel 26) The charging control panel 26 is embedded within the reinforcing liner 62 on the inner side of the shoe, with only a thin panel box exposed to the outside (Figure 1). The panel box of the charging control panel has controls for switching the fan's operation on and off, adjusting the fan speed, and a power supply port for charging the fan's battery. Specifically, a push-button type circular switch 26S with an illumination function and a display panel 26S for displaying the operating status are arranged side by side on the side of the panel box. The rear end of the panel box is covered with an openable / closable cap 26C (Figure 1). Opening this openable / closable cap 26C exposes the charging port.

[0040] (Sole sheet (3)) The sole sheet (3) consists of a sheet body that covers the upper surface of the sole plate and is equipped with ventilation openings (310M, 320M, 330M) (with mesh) in the foot shape foreground portion corresponding to the flow channel grooves (110, 120, 130).

[0041] Specifically, the ventilation openings of the sole sheet (3) consist of three first ventilation openings (310M), second ventilation openings (320M), and third ventilation openings (330M) arranged in order toward the toe of the shoe. The opening area is set to decrease in the order of the first ventilation opening (310M), second ventilation opening (320M), and third ventilation opening (330M), and each opening has a vertical trapezoidal, horizontal trapezoidal, and triangular shape, and a mesh-like net is formed inside the opening. Horizontal bars 31 and 32 are provided between adjacent ventilation openings to separate the openings (Figures 3 and 4). The edges of each of these three openings and the edges of the horizontal bars are formed to correspond to the positions of the vertical flow grooves, horizontal flow grooves, and toe-end flow grooves (170) of the sole plate 1 (Figure 5).

[0042] (Counter Heal (4)) The counter heel (4) is a curved plate that is located on the upper part of the sole sheet and surrounds the side or rear part of the heel section. Multiple protrusions (42, 43) are integrally formed on the outer surface of the plate, extending horizontally or diagonally downwards. The protrusions of the counter heel 4 form an intake channel that guides outside air drawn in from the outer surface of the sole into the enlarged hole 124, and also function as a reinforcing material inside the three-dimensional heel section to maintain moldability even when external force is applied.

[0043] (Articles 42, 43) The convex ridges of the counter heel are composed of multiple rows of diagonal convex sections (43) that extend diagonally downward on the side surface and horizontal ridge sections (42) that extend horizontally at the same height on the heel section, which are intermittently connected via vertically intermittent regions.

[0044] On the outer surfaces of both sides of the curved plate body of the counter heel (4), protrusions (42, 43) extend diagonally downward, and the ends of the protrusions are oriented toward the opening of the enlarged hole 124 or penetrate into the hole.

[0045] (Heel cover (5)) The heel cover (5) is made of a breathable fabric and covers the outer surface of the counter heel and forms the outer surface of the heel portion.

[0046] An elastic heel cover (5) is provided on the lower part of the heel upper (6HC) and on the outer circumference of the curved plate body of the counter heel (4), surrounding the protrusions of the counter heel (4). The heel cover (5) has a mesh-like opening extending along its sides or back, and the lower ends (5E) of both sides of the plate are embedded and fixed to the edge of the enlarged hole 124 of the sole sheet (3) or its vicinity. An intake channel is formed to guide outside air drawn in from the outer surface of the sole into the enlarged hole 124.

[0047] (Small opening 5M) Furthermore, the heel cover (5) has a mesh-like small opening 5M formed by a wire grid within the surface of the deformed spherical shape, excluding the periphery of the three-dimensional molded material, with honeycomb-shaped small holes arranged within it. This mesh-like small opening 5M on the heel cover is exposed to the outside of the air-conditioned shoe, giving it a distinctive appearance as part of the heel design.

[0048] (Protruding piece (5E)) The heel cover is composed of a curved horizontal line along its lower edge, excluding the tip, and has protruding pieces (5E) on both sides that project diagonally downwards in a parallelogram shape. The sole plate is provided with fixing holes corresponding to the protruding pieces 5E, and the protruding pieces (5E) at the lower ends of both sides of the plate are embedded and fixed in the holes of the enlarged holes 124 in the sole sheet (3) or in fixing holes near the front of them.

[0049] (Shoe upper (6)) The shoe upper (6) is constructed in a foot-covering shape from the periphery to the upper part of the sole plate, which is erected by fixing the sole sheet and overlapping the counter heel and heel cover, with a reinforcing part and a fabric body. Specifically, it consists of a periphery liner 61 that integrally covers the lower part, the side and the heel, a reinforcing liner 62 that reinforces the inner side of the shoe-covering shape in the vertical direction, an upper fabric 63, an eyelet 65 that is integrally formed with the center liner, a heel upper 6HC that seals the upper part of the heel and forms the opening, and a tongue 66 (Figures 1 and 2).

[0050] (Heel Upper - 6HC) In this embodiment, the heel upper-6HC, which constitutes the upper part of the heel structure, is sewn to the heel cover in a sealed state along the curved upper edge. The heel upper-6HC is composed of an outer fabric, a lining fabric, and an intervening material filled between them, and its lower edge consists of a line reinforcement section in which the outer fabric and lining fabric are tightly pressed together along the shape of the curved upper edge of the heel cover and further reinforced with a line-shaped resin material. This line reinforcement section tightly seals the curved upper edge of the counter heel and the upper edge of the heel upper, which is shaped to follow this upper edge, and also frames the structure of the airflow passage consisting of the counter heel and the heel cover.

[0051] (Reinforcement Liner 62) The reinforcing liner 62 consists of a thick reinforcing material containing lining reinforcing wires, which restricts excessive expansion and contraction of the shoe cover-shaped sides. Liner wires 25 (Figures 3, 4, and 5), which are wired to the box-shaped fan 2, are housed within the liner structure of the reinforcing liner 62, and a charging operation panel 26, connected to the end of the liner wires 25, is supported within an opening in the reinforcing liner 62, with the panel portion exposed (Figure 1).

[0052] (Three-dimensional heel section) The three-dimensional heel section has an internal structure consisting of a counter heel (4) that has an internal stress of elastic reaction force due to bending stress, and an external structure consisting of a three-dimensional molded heel cover that surrounds the counter heel (4) when bending stress is applied.

[0053] (Outside air intake channel) The convex shape and the heel cover seal the surrounding area, forming an air intake channel that draws in outside air from the outer surface of the sole and brings it into a box-shaped fan inside a box-shaped hole, while maintaining moldability. Air drawn in from the heel fabric of the heel upper 6HC is drawn in through the enlarged holes 124 on both sides of a box-shaped fan housed within a box-shaped hole. The exhaust air from the fan is expelled forward through the flow channel grooves in the sole plate and is blown upwards inside the shoe through the ventilation openings (310M, 320M, 330M) of the sole sheet.

[0054] (Flow channel grooves (110, 120, 130)) The multiple flow channel grooves (110, 120, 130) of the sole plate (1) are, Multiple vertical channel grooves (110, 120, 130) run parallel to each other from the front of the box-shaped hole towards the toes, These multiple vertical channel grooves are interconnected in the width direction at multiple points along the vertical grooves, and multiple horizontal channel grooves (140, 150, 160) are also provided. It is formed from a tip channel groove (170) that brings together all of the multiple vertical flow channels (110, 120, 130) in a curved line that follows the shape of the toe, The opening edge of the sole sheet is formed to correspond to the positions of the longitudinal channel grooves, the transverse channel grooves, and the tip channel groove (170).

[0055] The convex ridges of the counter heel are composed of multiple rows of diagonal convex sections (43) extending diagonally downward on the side surface and horizontal sections (42) extending horizontally at the same height on the heel section, which are intermittently connected via vertical intermittent regions. On the inner surface of the enlarged hole 124, vertical grooves are formed between each of the multiple protruding vertical columns. These vertical columns are formed at positions corresponding to the extended ends of the oblique protrusions.

[0056] The present invention is characterized by the following features.

[0057] By a box-shaped fan housed in the heel The heel structure, which is three-dimensionally molded by a double resin structure on the inside and outside, is exposed at the heel. Air is drawn in through small honeycomb-shaped openings formed on the entire back and sides of this heel structure, enters through a diagonally downward flow path on the side of the heel, and enters through enlarged holes on both sides of the box-shaped hole in the sole plate, where it is introduced into a box-shaped fan inside the box-shaped hole. The exhaust air from the front of the box-shaped fan blows air across the majority of the insole towards the upper part of the inside of the shoe.

[0058] The predetermined flow path is defined by horizontal and diagonal protrusions that secure space and define the flow path, with the three-dimensional curved space within the heel serving as the intake section, and each of the multiple flow paths separated by these protrusions being connected to slit-shaped enlarged holes on the side of the box-shaped fan, thus communicating with the top of the box-shaped fan as multiple three-dimensional flow paths.

[0059] The rows of convex ridges extending diagonally downwards from the horizontal on the heel counter maintain the shape of the internal space formed between it and the heel cover, and also function as internal reinforcement for the three-dimensional heel structure formed by the double-layered heel counter and heel cover, thereby ensuring durability.

[0060] The heel cover is made of an elastic resin molded body that has a three-dimensional spherical shape, and the entire spherical surface of this molded body, excluding the surrounding frame, has small mesh-shaped openings, making the entire surface an air intake area, thus enabling efficient air intake.

[0061] The sole plate is made of integrally molded elastic resin, and a box-shaped hole and a flow channel groove are continuously formed on the upper surface of the plate, and the housed box-shaped fan draws in air along the vertical groove spaces on both sides of the housing hole, and the box-shaped fan, while housed, blows air along the flow channel grooves in the direction of three curved lines plus intersecting lines that are connected to the box-shaped hole for housing the fan in the sole plate.

[0062] The method for air-conditioning shoes using the air-conditioned shoes of the present invention consists of the following steps.

[0063] 1. Heel intake step in a horizontal to diagonal-downward direction. Outside air drawn in from the back and sides of the shoe heel travels diagonally downwards and to the left and right of the heel along the convex grooves of the heel counter, and flows downwards through the longitudinal grooves on both sides of the heel of the sole plate.

[0064] 2. Air blowing step from the "front-top" surface through the housing hole in the sole plate: Air blown in from the slit openings on the front side of the box-shaped fan travels through the flow grooves in the sole plate towards the toe, and is blown upwards over the majority of the toe area inside the shoe through the mesh net of the insole.

[0065] 3. Exhaust step: Air is blown upward from the toe area of ​​the insole and exhausted to the outside of the shoe through the mesh fabric and gaps in the shoe's upper, throat, and tongue.

[0066] Furthermore, the present invention is not limited to the embodiments described above and can be modified in various ways. Combinations of individual elements, extraction of some elements, disassembly into individual parts, or integrated configurations are all possible. [Explanation of Symbols]
