Description

  The present invention relates to footwear and footwear parts that improve the environment inside the footwear and facilitate the addition of electronic functions.

Conventionally, as a factor that deteriorates the comfort of footwear, there is the occurrence of stuffiness and bad odor inside the shoe, and various attempts have been made to structure air flow between the inside and outside of the shoe to prevent this. It has been. For example, a structure in which an outsole of a toe or arch is opened to take in outside air is known. In this case, the insole needs to be made of a highly breathable material. In addition to this, there are air pumps and air blowers provided in the heel portion, and forced air is forced into the toe portion via a ventilation pipe.

  The problem to be solved is that the footwear provided with an opening in the conventional outsole described above, rainwater easily infiltrates into the footwear from the opening of the outsole if a slight water puddle is stepped on, In addition to feeling uncomfortable, it sometimes accelerated footwear damage. In addition, it is necessary to use a highly breathable insole material, and there is a problem that comfort is deteriorated. As an improved version, a moisture-permeable waterproof sheet is interposed between the opening of the outsole and the insole to prevent the infiltration of rainwater. However, the moisture-permeable waterproof sheet is clogged by dust and is naturally The air flow was hindered and the ventilation performance was reduced.

  On the other hand, footwear provided with an air pump or blower on the heel uses the load difference applied to the heel when walking, so there was the inconvenience that ventilation was not sufficient when there was no walking movement, such as when sitting. . In addition, the air pump and blower at the heel part and the ventilation duct at the sole part are prone to failure due to impact and bending during walking, and have a physical thickness and volume that restrict the design of footwear. It was difficult to apply to other footwear. In addition, footwear that uses a moisture-permeable waterproof sheet for the waterproofing of the upper and the vents of the outsole has been put to practical use. However, as described above, there was a problem that sufficient ventilation performance could not be exhibited when sweating. . Moreover, since the impact of walking and the inside of the footwear are always humid, it is not preferable as an environment for using the electronic device, so it is difficult to control the environment inside the footwear according to the situation using electronic technology.

  The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a ventilation mechanism that prevents the infiltration of water while promoting natural ventilation inside the footwear. It is another object of the present invention to provide footwear that can be ventilated according to the environmental conditions inside the footwear even when seated, and that has a higher degree of design freedom and electronic functions.

  In order to solve the above-mentioned problem, a first feature of footwear according to the present invention includes a ventilation pipe that communicates an interior air opening that opens inside the footwear and an outside air opening that opens to the outside, and the ventilation pipe The road has water resistance with respect to the inside of the footwear and has a highest point in the middle between the inside air mouth and the outside air mouth.

  As a result, a passage that can directly exchange the steamed inside air of the footwear and cool outside air can be secured, and the ventilation line will be used as long as it does not exceed the highest point of the ventilation line even if water or dust infiltrates from the outside air mouth. Since it is water resistant to the inside of the footwear, it cannot penetrate into the inside of the footwear. As a result, the ventilation volume is increased to improve the ventilation performance of the footwear, and at the same time, it is possible to simultaneously achieve the waterproof deterioration due to the improvement of the ventilation performance, which has been a problem.

  In a further preferred aspect, the highest point of the ventilation line is higher than the insole of the footwear. According to this configuration, even if the outside air port is disposed at a position lower than the insole such as the bottom of the sole, the outside air port is equivalent to the case where the outside air port is disposed on the upper part of the upper part of the footwear. For this reason, even when there is a depth of water up to the height of the insole, it is possible to prevent water from infiltrating directly from the outside air port. On the other hand, for rain, there is no fear that the rain flows directly from the outside air mouth because there is no outside air mouth serving as an opening in the upper part of the crust.

  In a further preferred aspect, the toe portion of the footwear includes the outside air mouth, the inside air mouth, and a structure having water resistance that constitutes the ventilation duct adjacent to the crust. According to this configuration, in many footwear, the toe portion is provided with a space (toe box) for ensuring the movement of the toe during walking and showing the shape of the footwear well. A structure constituting the ventilation line having the highest point can be provided. As a result, the ventilation performance of the toe portion that requires the most ventilation in the footwear can be improved without changing the appearance of the footwear. Moreover, although the tip which reinforces this space may be used, the said structure can be substituted for a tip. Furthermore, a ventilation conduit can be configured by combining the structure and the upper shell. In addition, since the inside air mouth, the ventilation pipe, and the outside air mouth are located near the toe part that is most likely to be steamed inside the footwear, the flow resistance of the ventilation pipe is reduced, and high ventilation performance is obtained.

In addition, by implementing an electronic device using a structure that forms a space in the toe part where there is room in the overall structure of the footwear and it is difficult to apply external force, advanced ventilation controllability is realized and the control system is expanded. New functional equipment becomes possible. That is, it becomes possible to arrange | position a ventilation apparatus other than an outsole part because a ventilation duct exists in a toe part. Furthermore, by mounting the electronic device on a water-resistant structure provided on the toe portion, it is possible to open a way to add advanced air conditioning functions and intelligent functions to footwear while ensuring the reliability of the electronic device.

  In a further preferred aspect, the ventilation duct and the interior air port are formed integrally with the structure. According to this structure, since the inside air mouth can be disposed in the footwear near the toe portion that is most likely to be stuffy, the flow resistance of the ventilation line is reduced, and high ventilation performance is obtained. In many footwear, a space (toe box) is provided in the toe portion to secure the toe movement during walking and to show the shape of the footwear well, so ventilation is not hindered by the position of the foot. Ventilation means can be provided without difficulty using space.

  In a further preferred aspect, the outside air opening is opened at a toe portion, and the ventilation duct and an inside air opening where the ventilation duct opens into the footwear are formed integrally with the tip core structure. According to this structure, even if it is a complicated structure of ventilation ducts and inside mouths, it is integrally molded as a lead-core structure using plastic, metal, or composite material separately from the upper and sole members of footwear Can do. In addition, since it can be separately formed as a toe-end structure, a small blower that is electronically controlled and its control device are mounted in the ventilation duct or in the toe-end structure, so that they can be externally supplied. It can protect against impact and dust.

  In a further preferred aspect, the outside air port is disposed through the outsole of the toe box portion (toe portion). That is, the outside air port is formed in a range that warps upward on the lower surface of the front end portion of the outsole. According to this structure, since the outside air port is disposed in the part where the ground contact surface of the outsole portion is slightly lifted, it is easy to take in outside air even when sitting or standing. Further, since there is no outside air mouth in the upper part, the appearance of conventional footwear is not greatly changed. Furthermore, it is not affected by the deterioration of ventilation performance due to clogging of the outside air mouth due to maintenance such as glazing and waxing on the upper.

  In a further preferred aspect, the vicinity of the outside air port of the ventilation pipe is formed so that the cross-sectional area of the pipe increases toward the outside air. In other words, the outside air port end portion of the ventilation pipe is continuously or stepped inwardly from the outside air port. According to this structure, since the ventilation duct portion toward the outside air port is disposed in the vertical direction, water and dust that have infiltrated from the outside air port are easily discharged to the outside due to gravity. For this reason, compared with the case where the ventilation pipes are arranged in the horizontal direction, the ventilation pipes are not easily clogged even when water or the like enters, and the ventilation performance is easily maintained.

  In a further preferred embodiment, the inside mouth faces the gap between the structure and the toes. More preferably, it arrange | positions centering on the position which opposes the index finger of a foot | leg. According to this structure, the outside air sent from the inside mouth is diffused in a space in front of the toes of the toes and then flows through the gaps between the toes. As a result, the high-temperature air accumulated between the toes is stably discharged toward the mouth through the gap space between the foot and the insole of the footwear and the crust. For this reason, ventilation performance can be improved compared with the case where there is an inside air mouth on the insole surface where ventilation is easily disturbed on the back of the foot. In addition, since the insole is not on the insole surface, the material and structure of the insole can be selected giving priority to comfort.

  In another aspect, a forced ventilation device is disposed in the ventilation line adjacent to the interior air port. According to this structure, since the ventilation line length is short, it is possible to blow air from the inside air mouth without attenuating the blowing force of the forced ventilation device. In addition, since the conventional footwear originally has a play space (toe box) in front of the toes of the toes, even if a forced ventilation device is disposed adjacent to the inside air mouth, the size of the footwear does not affect the appearance of the footwear. Few. Furthermore, since an external force is not directly applied to the forced ventilation device because it is protected by the upper skin part or the tip core structure, a failure due to the external force of the forced ventilation device can be avoided.

  In a further preferred aspect, the ventilation conduit reaches below the forced ventilation device at the end on the inside air port side. Specifically, the forced ventilation device is fixed to the tip core structure at a position higher than the lowermost part of the ventilation duct. According to this structure, even if water droplets are generated in the ventilation pipeline due to condensation or the like, the water droplets are accumulated at the lowermost portion of the ventilation pipeline, and it is difficult to reach the position where the forced ventilation device is fixed. As a result, the probability that water drops adversely affect the forced ventilation device having an electrical rotation mechanism can be greatly reduced.

  In another aspect, the forced ventilation device is electronically controlled by a control device in accordance with humidity and / or temperature inside the footwear, and the control device is stored in the lead core structure. . According to this configuration, the integrated circuit (LSI) control device receives the output data from the humidity and / or temperature sensor embedded in the footwear, and provides optimal ventilation in a timely manner with a short wiring to the forced ventilation device. The number of rotations of the blower fan can be controlled so as to be the amount. Furthermore, the reliability of the control device can be improved by storing the control device in a tip-core structure having water resistance and mechanical strength.

  As a preferred embodiment of the present invention, a breathable member is coated on the inner side of the upper side of the footwear from at least the inside mouth to the footwear portion. According to this structure, the outside air sent out from the inside mouth passes through the breathable member provided on the inner side of the upper part of the footwear, flows to the mouth, and is discharged outside the footwear. Ventilation performance can be increased. The air-permeable member is preferably a loofah fiber structure having a large space in the blowing direction.

  In another aspect, the control device controls another electronic device mounted on the footwear in response to a signal input from an input means embedded in the upper member of the footwear. According to this configuration, the operation of the forced ventilation device and the control of various electronic devices that can be mounted on the footwear are greatly controlled by the input means mounted on the member of the upper part that is most easily operated by the person wearing the footwear. It is possible to instruct the control device without cost. Examples of various electronic devices include displays, light emitters, sensors, speakers, and wireless devices.

  The footwear structure of the present invention is provided with a ventilation line for ventilating inside air and outside air inside the footwear, and an inside air opening in which the ventilation line opens into the footwear. According to this structure, even if it is a complicated structure ventilation pipe | tube_line or inside-mouth shape, it becomes possible to manufacture in a process different from a footwear manufacturing process, and to incorporate in a footwear as a quality-guaranteed module part. As a result, the productivity and quality of footwear can be significantly improved compared to the case where the ventilation means are individually made.

  As another aspect of the present invention, an electronic device for adding a function for improving the convenience and comfort of a user of footwear or a function for improving the productivity of a producer / distributor is mounted in the structure. According to this configuration, the toe portion has a space, and the structure is preferably made of a molded product of plastic or metal. Therefore, even in an electronic device that is easily affected by moisture and stress, It is easy to mount the electronic device so as to be wrapped with the structural member of the structure. In addition, since the toe portion is less susceptible to impact among the constituent members of the footwear and the degree of influence of the constituent materials on the comfort is low, it is possible to select a material that prioritizes the protection characteristics of the electronic device. Furthermore, by providing the ventilation mechanism of the present invention, the humidity around the electronic device can be kept low, so that the moisture resistance cost of the electronic device can be kept low. Accordingly, it is possible to mount electronic devices and other functional parts on footwear while suppressing generation of new costs and mounting space, and promote new added value to the footwear.

  As a preferred aspect of the invention, a power supply device for supplying electric power for operating the forced ventilation device and the control device is disposed in the vicinity of the boundary between the foot portion and the tongue (tongue) portion of the footwear. According to this configuration, if the power supply device needs to be replaced like a primary battery, the user can easily replace it. Moreover, since the impact and pressure accompanying walking are not directly applied to the power supply device, the power supply device can be easily mounted. Further, by covering the power supply device with the members constituting the blade part and the tongue part, it is possible to suppress the influence of deterioration due to impact or moisture. Further, the power supply device can be made inconspicuous in design, or can be a part of decoration.

  Embodiments of the present invention will be described below with reference to the drawings. The form shown below shows one mode of the present invention, and is not limited to the present invention, and can be arbitrarily changed within the scope of the present invention. Further, in the respective drawings shown below, the dimensions and ratios of the respective constituent elements are appropriately different from the actual ones so that the respective constituent elements can be recognized on the drawings. Further, in any of the drawings, a detailed portion is omitted as long as the contents of the present invention can be understood. In addition, the same code | symbol is attached | subjected to the same member in these drawings, and the duplicate description is abbreviate | omitted.

[Embodiment 1]
FIG. 1 is a perspective view showing a configuration of footwear provided with a tip-toe structure 1 of the present invention, which is Embodiment 1 of the present invention, in a toe portion 40. FIG. 2 is a cross-sectional view of the tip core structure 1 taken along line AB in FIG. This is shown with a part of the ventilation duct. FIG. 3 is a plan perspective view of the toe portion 40 as viewed from the upper side of the footwear. FIG. 4 is a plan view seen from the outsole side of the present invention.

  1-4, 100 shows the whole footwear, and footwear 100 is roughly shown outsole 3 (outsole), insole (insole) 4, upper (upper) 2, and a lead core structure. 1. In the following description, details of the present invention will be described focusing on leather men's business shoes, but the present invention is not limited to this.

  The outsole 3 is integrally formed of a synthetic resin such as leather or polyurethane, or an elastic foam material. In the conventional footwear, the toe core structure 1 corresponds to a toe core that is inserted into the tip of the shoe in order to secure an upper space (toe box) of the toe portion 40, but the present invention is not limited to this. The core structure 1 is formed of a lightweight water-resistant material such as a composite resin material (ACM) including a fiber material, elastic polycarbonate, polyurethane, or the like. In the present invention, since the tip core structure 1 is not intended to ensure safety against dropping of heavy objects, the tip core structure 1 is not necessarily formed of a hard material and does not cover the entire toe. A shape covering up to the top is preferred. As shown in FIG. 2, the bottom side of the lead core structure 1 has an overhang portion 23 that wraps around the lower side of the insole, and is embedded and fixed in the outsole 3 portion so as to be covered with the crust.

  As shown in FIG. 2, the lead core structure 1 is provided with ventilation ducts 20 and 21 for increasing the waterproof height of the footwear at the head portion. The ventilation duct 20 is formed of a water-resistant material that does not allow water to permeate in a short time or more, and extends from the outside air opening 19 that opens to the outsole 3 to the top of the leading end structure. After passing through the core structure upper part 22, it descends to the head part of the tip core structure and is connected to the inside air port 17 that is an opening to the toe box 9. As shown in FIG. 2, the outside air port 19 preferably opens at a portion where the toe portion of the outsole 3 warps upward. In the present embodiment, as shown in FIG. 3, the outside air port 19 is composed of two outside air ports 31 and 32, and two ventilation lines 35 rise from the outside air ports 31 and 32, respectively. They join at the uppermost portion 22 of the core structure, which is the highest point, and are connected to the ventilation duct 36. In the case where a plurality of ventilation lines are provided, the highest point area of the optimum ventilation line in footwear is limited.

  The upstream ventilation pipe 20 and the outside air port 19 have a structure in which the diameter of the ventilation pipe increases toward the outside in order to prevent clogging of the pipe line due to surface tension of water and foreign matters. Further, the minimum diameter of the upstream ventilation duct 20 is set to a value larger than about 0.7 mm, preferably 2 mm or more, at which water does not penetrate into the duct against the gravity due to capillary action. The cross-sectional shape of the ventilation duct 20 is not limited to a circular shape, and is configured in an arbitrary shape according to the shape of the footwear. Further, the ventilation duct 20 and the outside air port 19 attenuate the momentum of water entering the outside air mouth 19 during walking, or prevent foreign objects from reaching the inside of the footwear and damaging the foot. As shown in FIG. 5, it is preferable to curve the ventilation conduit three-dimensionally. Furthermore, it is preferable that the ventilation duct 20 extends obliquely toward the heel side toward the outside air port 19 at the end on the outside air port 19 side (FIG. 2). Further, in order to prevent foreign matter from clogging the outside air port 19, a lattice may be provided at the outside air port 19 portion. Due to the above structural features, even if rainwater infiltrates from the outside air port 19, if it does not exceed the uppermost part 22 of the ventilation duct, the rainwater that has been discharged from the outside air port 19 is discharged from the outside air port 19, and the inside air port 17. Never reach.

  Further, in order to reduce the weight of the lead core structure 1, it is preferable to hollow out a thick portion other than the ventilation pipe as shown by hatched portions 33 and 34 in FIG. The cavities 33 and 34 can be formed at the same time as the ventilation pipe, and can be a space for mounting an electronic device to be described later or a new ventilation pipe.

  Further, a breathable member 13 is covered up to the mouth portion 5 inside the tip core structure 1 and the buffer member 14 at the end thereof. Therefore, a frame member for fixing the end of the air-permeable member 13 may be fitted to the inside air port 17. According to this structure, the airflow F3 delivered from the inside mouth 17 shown in FIG. 2 flows through the breathable member provided on the inner side of the upper part of the footwear to flow to the portion of the footwear. Since it is discharged to the outside, ventilation performance can be improved. The air-permeable member is preferably a loofah fiber structure having a large space in the airflow direction.

  According to the above configuration, the low-temperature, low-humidity air flow F1 is introduced from the outside air opening 19 slightly floated from the floor surface 25 even when seated, and the ascending ventilation pipes in the outsole 3 and the front core structure 1 are introduced. 20, reaches the upper tip 22 of the lead core, and then flows into the toe box 9 as air currents F <b> 2 and F <b> 3 from the inside air port 17 via the down ventilation duct 21 in the tip core structure 1. Due to the ventilation airflow, the air in the toe box 9 that has become hot and humid due to heat generation and sweating of the foot passes through a space formed between the upper 10 and the instep 15 or the insole 15 and the sole. It is discharged to the mouth 5. In the air circulation path configured as described above, the wear mouth 5 is located at a higher position than the outside air port 19. Therefore, a negative pressure acts on the outside air port 19 due to the chimney effect, and natural circulation of air is performed. Further, during walking, the intake and exhaust through the ventilation line of the present invention is performed in addition to the ventilation by the natural circulation path described above, due to the bellows action in which the spatial volume of the toe box 9 is changed by the movement of the foot. . As a result, fresh outside air is directly introduced into the toe, so that discomfort inside the footwear is greatly reduced.

  2 and 3 is formed by separately forming the outer member 11 and the inner member 12 using a mold and bonding them together. Thereby, even a complicatedly shaped ventilation pipe can be easily formed. Further, it is possible to easily mount a forced ventilation device, another electronic device, or the like in the ventilation pipeline at the time of bonding.

[Embodiment 2]
FIG. 5 is a cross-sectional view of the center portion of the lead core structure 37 provided with the forced ventilation device of the present invention, which is Embodiment 2 of the present invention, taken along line CD in FIG. This is shown with a part of the ventilation duct. FIG. 6 is a plan perspective view of the tip core structure 37 part. FIG. 7: is a perspective view which shows the component arrangement | positioning regarding the forced ventilation of the footwear provided with the forced ventilation apparatus of this invention which is Embodiment 2 of this invention. Since Embodiment 2 adds the component related to a forced ventilation apparatus with respect to Embodiment 1, description of a common part is abbreviate | omitted.

  In FIG. 5, the forced ventilation device 50 is disposed in such a manner as to slightly expand the downward ventilation duct 21 in the tip-core structure 37. The attachment position of the forced ventilation apparatus 50 is arrange | positioned in the ventilation pipe line 21 adjacent to the inside air port 17, as shown in FIG. 5, FIG. The forced ventilation device 50 can be mounted without affecting the outer shape and the comfort of the footwear since the combined thickness of the blower blades and the motor can be about 4 mm. In FIG. 5, the forced ventilation device 50 takes in outside air that has passed through the ventilation line from the upper surface of the forced ventilation device 50, and blows air by bending the wind direction in a right angle direction. The casing of the forced ventilation device 50 may be integrally formed with the tip-core structure structure, but it is attached to the tip-core structure via a suspended structure or a flexible member that relieves external shock and vibration caused by forced ventilation. It may be attached. Further, if there is a support for obtaining the space strength between the outer tip core structure 11 and the inner tip core structure 12 near the forced ventilation device 50, the impact strength can be further improved. Moreover, the height from the floor surface of the bottom part 30 as the lowest part of the ventilation pipe line 21 shown by h3 of FIG. 5 is formed to be a position lower than the bottom surface height h4 of the forced ventilation device. Thereby, the influence probability to the forced ventilation apparatus by the water | moisture content and dust which arose in the ventilation pipe line can be reduced.

  The forced ventilation device 50 is preferably a cross-flow fan using an ultra-compact brushless DC motor with a sealed bearing structure, but a propeller fan, other type of fan, blower, bellows type pump, ion conductive polymer actuator or the like. A device having an air blowing function such as an air blowing device using the above may be appropriately selected and used. In the case of a cross flow fan, the wind direction can be bent at a right angle, and the air flow is a quiet laminar flow with the width of the fan, which is convenient for achieving the object of the present invention. In this case, even with a size of about 15 mm long × 4 mm in diameter, there is a maximum blowing capacity of about 0.010 m 3 / min, which is sufficient to ventilate the footwear. The fan is resin-molded, and its weight is about several g to several tens g, and does not affect the center of gravity balance of footwear. The rotation axis of the cross flow fan may be integrated with the rotation axis of the DC motor and arranged in the direction of the rotation axis, but the cross flow fan and the DC motor may be arranged vertically by way of a gear or a belt. Good. In the case of vertical stacking, the space in the ventilation pipe can be used effectively, and a motor with a large torque can be used. In the case of a propeller fan, in FIG. 5, the forced ventilation device 50 is arranged in the vertical direction with respect to the rotational surface of the fan. May be. In this case, it is necessary to secure a ventilation space between the forced ventilation device and the inside air mouth.

  In FIG. 7, the forced ventilation device 50 controls the amount of blown air by changing the pulse width and phase of the drive current using the control device 70 using three or more phases. The control device 70 has a semiconductor integrated processor and motor driver as main components, and operates by receiving power supply from a power supply device 73 through a conductor 76 embedded inside the upper shell. The control device 70 also performs inverter control on the pulse width and phase of the drive current according to the detection signal sent from the temperature and humidity sensor 72 mounted on the footwear via the conductor 71, so that the toe portion 40 is comfortable. The air flow rate of the forced ventilation device 50 is adjusted so as to be maintained. For example, when the tip portion is hot and humid, the air flow is increased, and when the temperature is below a certain temperature, the air blowing is stopped. In the middle, the air flow rate is controlled so that ventilation is performed gently. Thereby, the power consumption of the forced ventilation apparatus 50 is suppressed significantly.

Further, when the footwear is not worn, the entire apparatus is controlled to stop its operation and consume little power. The fact that the footwear is not worn can be detected by an output signal from the temperature sensor or the humidity sensor, but may be controlled by an automatic detection method using a pressure sensor, an infrared sensor or a vibration sensor, or a manual switch. . In addition, when walking, the forced ventilation device 50 is brought into a free-run state by detecting the walking motion by a pressure sensor, a vibration sensor, a back electromotive force of a motor, etc., so that the positive ventilation by the above-mentioned bellows action is performed on the ventilation pipe. It may be performed without any obstacles via the road.

  The control device 70 may be integrated with the forced ventilation device, or may be mounted in such a manner that a part or all of the control device 70 is embedded in the lead core structure 80. Thereby, corrosion and deterioration of the electronic device due to moisture such as sweat can be prevented.

  The power source device 73 is a button type primary battery or paper battery that is thin and light and suitable for mounting. However, other types of primary batteries and secondary batteries, fuel cells, Peltier elements, solar cells, DC type fan motors, etc. are used. A combination of a power generation device and a power storage device may be used. When using a button-type primary battery, for example, as shown in FIG. 7, the button-type primary battery is disposed at or near the overlapping portion of the blade portion 6 and the tongue portion 7, and the inside of the upper portion is connected by a conducting wire 76 to supply power to the control device 70. . Accordingly, when a plurality of button-type primary batteries are used, by using a soft battery pack 74 with high confidentiality, the battery can be disposed at a position that does not hinder the shape of the foot or the movement of the foot, and the battery can be easily replaced. . In addition, by reducing the power consumption by changing the motor speed of the forced ventilation device 50 described above over a wide range, even with a button type lithium battery of about CR2032, it is possible to ensure a practical battery life of about 2-3 weeks. It is.

[Embodiment 3]
FIG. 8: is a top view which shows the structure of the footwear provided with the tip core structure 80 of this invention which is Embodiment 3 of this invention. This embodiment is an embodiment suitable for footwear with a long nose, and the outside air ports 81 and 82 are located on the front end side of the footwear from the ventilation duct bottom portion 86 in the front core structure 80. The ventilation duct bottom portion 86 corresponds to the ventilation duct bottom portion 30 of FIG. Further, a plurality of inside air ports 83, 84, 85 may be provided. In this case, since the cross-sectional area of the ventilation path can be increased, higher ventilation performance than that of the first embodiment can be obtained. Also in this case, there may be one or a plurality of outside air ports and ventilation lines, and the arrangement pattern of the ventilation lines can be arbitrarily changed according to the shape of the footwear and the ventilation performance. 8 is formed by separately forming and bonding the intermediate member in addition to the outer member and the inner member. The ventilation path has an ascending ventilation line 87 that rises from the outside air ports 81 and 82 to the top 22 of the ventilation line, and a down ventilation line 88 that descends from the top 90 toward the inside air ports 83, 84, and 85. is doing. Similar to the bottom of the lead core structure 1 in FIG. 2, the bottom of the lead core structure 80 has an overhanging portion 89 that wraps around to the lower side of the insole, and is embedded in the outsole 3 in a form covered with the crust. It is fixed.

  As described above, in the present embodiment, the outside air introduced using the ventilation pipe is sent to the space of the toe portion as indicated by the arrows in FIGS. 2 and 5, so that the toe as described in the first embodiment. The humid air of the part is pushed out to the upper part of the foot or the arch part, and is exhausted from the wearing mouth 5 through the gap between the foot and the upper part of the shell. In other words, cool and damp outside air is always introduced into the toes where there are many sweat glands and most likely to cause athlete's foot. In addition, since ventilation is performed by natural ventilation due to the chimney effect or forced ventilation device even when sitting without walking, the toes are always kept comfortable, and athlete's foot and odor can be prevented.

  As mentioned above, although the footwear provided with the ventilation mechanism integrated with the tip core structure of this invention was demonstrated based on embodiment, this invention is not limited to these embodiment, A various deformation | transformation is possible. For example, as long as it is below the highest point of the ventilation pipe, the outside air port 19 may be disposed on the side of the upper part or the side of the outsole 3. Further, the ventilation line connected to the outside air port may be separately provided for intake and exhaust. In this case, if a forced ventilation device is provided in either the intake ventilation duct or the exhaust ventilation duct, ventilation in the toe box at the time of sitting is further promoted than in the second embodiment.

  As yet another modified example, in Embodiment 1 of the present invention, the lead core structure 1 is formed by being divided into the outer member 11 and the inner member 12 and bonded together. , 21 may be formed by opening the portion on the crust side and replacing the opened ventilation duct wall portion with the crust 10 so that the tip core structure 1 is formed of a single member. Alternatively, as shown schematically in FIG. 9, the tip core structure 1 opens the pipe wall of the upper side of the upstream ventilation pipe 20 and the upper part of the tip core 22 and opens the opened ventilation pipe wall. While covering with the leather 10, the pipe wall of the front lining side part of the descending ventilation pipe 21 is opened, and the ventilation pipe wall is formed by covering the opened ventilation pipe wall part with the front lining 13. Thus, the up ventilation duct and the down ventilation duct may be collectively formed as one member. In this case, it is preferable to use a water-resistant material for the lead core structure 1 and to use a moisture-permeable waterproof material (including a moisture-permeable waterproof sheet attached to the leather). This modification can realize footwear with lower cost as a simple embodiment of the present invention. The above-described simple ventilation pipe structure can be applied to the second and third embodiments of the present invention.
