Further, the present invention has an effect that the cushioning force can be maintained for a longer time by delaying the air stored in the air tube as much as possible from being discharged into the footwear.
In addition, the present invention has an effect that exhausted air can be intensively supplied to a site where sweat is generated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 attached herewith is a diagram showing the overall configuration of a ventilated footwear. As shown in FIG. 1, the ventilated footwear includes an upper shell 10 that forms an outer shape, an insole 12 (or a pad) that forms the bottom of the upper shell 10, an insole 14, and a footwear bottom main body 16.
On the other hand, a cushion and a ventilation device 20 which constitutes a main component of the present invention are installed on the bottom surface of the ventilation shoes, preferably under the insole 12. Hereinafter, the cushion and the ventilation device 20 according to the present invention will be described as being limited to be installed under the insole 12, but the ventilation device 20 is manufactured by being inserted into the inside bottom 14 by an insert injection method, Alternatively, it may be installed in a state of being fitted between the insole 14 and the footwear bottom body 16, which will be obvious to those having ordinary knowledge in the field.
Attached FIG. 2 is a plan view of the cushion and ventilation device 20. As shown in FIG. 2, the cushion and ventilation device 20 is provided with an air pump 22 at the rear, and an air tube 38 is connected to the air discharge pipe 30 provided in the air pump 22 by a connecting pipe 44. Has a structure. The air pump 22 sucks external air by contraction and restoration operations and discharges the air to the air discharge pipe 30, and the air discharged to the air discharge pipe 30 is formed in the air tube 38 through the connection pipe 44. The air chamber 48 is stored.
FIG. 3 attached herewith is an exploded view showing the configuration of the cushion and the ventilation device.
As shown in FIG. 3, the air pump 22 includes an upper sheet 24 and a lower sheet 26.
The upper sheet 24 is made of a polyurethane (PU) material, and a hollow portion 24a of a certain size is formed at the center.
The lower sheet 26 is made of a polyurethane material having the same physical properties as the upper sheet 24, and is attached by heat-sealing the peripheral surface thereof at a high frequency with the upper sheet 24 placed thereon.
A suction hole 26 a is formed in the center of the lower sheet 26. The suction hole 26 a allows the outside air to be sucked into the hollow portion 24 a in the upper seat 24 when the air pump 22 composed of the upper seat 24 and the lower seat 26 contracts.
An elastic film 28 is attached to the inner surface of the lower sheet 26 in which the suction hole 26a is formed. The elastic membrane 28 is elastically bent by the pressure of the air sucked into the suction hole 26a, and when air is sucked into the hollow portion 24a with the function of opening the suction hole 26a, the pressure of the sucked air is increased. The suction hole 26a is sealed again to prevent the air from being discharged to the outside.

As described above, the air discharge pipe 30 is integrally extended on one side of the air pump 22 constituted by the upper sheet 24 and the lower sheet 26. The air discharge pipe 30 is a pipe through which the air sucked by the air pump 22 flows into the connection pipe 44 of the air tube 38, and a valve 31 is built in the air discharge pipe 30.
Meanwhile, a sponge 32 is built in the air pump 22. The sponge 32 is inserted into the hollow portion 24a of the upper sheet 24 before the upper sheet 24 and the lower sheet 26 are heat-sealed. The restoring force (that is, the pumping operation) increases the restoring force of the air pump 22, particularly the upper seat 24, with its own cushioning force so that the restoring force of the air pump 22 does not decrease. It is possible to prevent a decrease in force.
A separate elastic member 36 is further provided on the sponge 32. The elastic member 36 is made of a material having elasticity such as rubber, and the elastic member 36 includes a flat portion 36a that is in close contact with the upper surface of the sponge 32, and a peripheral surface of the flat portion 36a. The elastic protrusion 36b is provided along the surface of the sponge 32 and surrounds the peripheral surface of the sponge 32. The elastic member 36 elastically increases the restoring force of the sponge 32, and when the elastic protrusion 36b provided on the elastic member 36 is not restored from the collapsed state in the process of the sponge 32 being contracted, The sponge 32 is restored by elastic reinforcement.
On the other hand, the air tube 38 is a state in which the upper sheet 40 and the lower sheet 42 made of polyurethane (PU) are brought into surface contact with each other, and the peripheral surfaces thereof are heat-sealed at a high frequency, thereby the upper sheet 40 and the lower sheet 42. The connecting pipe 44 and the air chamber 48 that is extended from the connecting pipe 44 are formed.
A non-conductor 46 made of a material such as polyethylene (pe) or polypropylene (pp) is fitted into the inlet of the connecting pipe 44. The non-conductor 46 blocks the sealing of the inlet 44 a of the connecting pipe 44 in the process of thermally fusing the peripheral surfaces of the upper sheet 40 and the lower sheet 42.
That is, as described above, the non-conductor 46 is made of a material (polypropylene) having physical properties different from those of the upper sheet 40 and the lower sheet 42, so that the non-conductive body 46 is formed on the inlet 44a side where the connection pipe 44 is formed. When the entire peripheral surfaces of the upper sheet 40 and the lower sheet 42 are heat-sealed in a state where the non-conductor 46 is fitted, the upper sheet 40 and the lower sheet 42 are formed in the portion where the non-conductor 46 is fitted. Since they are not brought into contact with each other, heat fusion does not occur, and therefore, it can be manufactured with the inlet 44a of the connecting pipe 44 open.

The non-conductor 46 also functions as a check valve that allows air to pass only in one direction. As shown in FIGS. 7A and 7B, when air is supplied to the air discharge pipe 30 by the pumping operation of the air pump 22, the non-conductor 46 and the connection pipe line 44 are connected by the supplied air pressure. A gap K is generated therebetween, and air can be stored in the air chamber 48 via the connecting pipe 44 through the gap K. Further, when the supply of air is completed, the non-conductor 46 and the inlet 44a of the connecting pipe 44 are brought into close contact with each other, so that the reverse flow of the air stored in the air chamber 48 can be blocked. The description will be described in more detail in the following description of the operation.
FIG. 4 attached herewith shows the air chamber provided in the air tube in more detail.
As shown in FIG. 4, the air chamber 48 is means for storing air supplied through the inflow conduit 44 for a certain period of time and providing cushioning force to the pedestrian's feet to alleviate the impact. .
That is, when air is introduced into the air chamber 48 through the inflow conduit 44 by the pumping operation of the air pump 22, the air chamber 48 expands and inflates, and thereafter, the sole of the foot contacts the air chamber 48. When this happens, the air chamber 48 is elastically pressed to absorb the impact on the sole of the foot.
A heat fusion part 50 is formed in front of the air chamber 48, and an auxiliary chamber is separately formed. At this time, a discharge flow path 50a is formed in the center of the heat fusion part 50 so that air stored in the air chamber 48 can pass through the auxiliary chamber.
The auxiliary chamber is divided into three spaces, specifically, a central auxiliary chamber 52 communicating with the discharge flow path 50a, and side surfaces partitioned by auxiliary fusion portions 56 on both sides of the central auxiliary chamber 52. The auxiliary chamber 54 is divided. At this time, each auxiliary flow path 56 a is formed in the auxiliary fusion part 56, and the branch flow path 56 a allows the air stored in the central auxiliary chamber 52 to pass through the side auxiliary chamber 54.
A discharge port 58 is formed through the side auxiliary chamber 54. The outlet 58 discharges the air supplied to the central auxiliary chamber 52 and the side auxiliary chamber 54 to the inside of the footwear, preferably between the toes of the user, thereby realizing a ventilation effect.
That is, as described above, the air chamber 48 is thermally fused 50 to form a separate auxiliary chamber 48a, and the air chamber 48 is configured to communicate with each other via the discharge channel 50a and the branch channel 56a. This is because the cushioning force of the air chamber 48 can be maintained for a longer time by delaying the time during which the air stored in 48 is discharged into the footwear as much as possible.

Attached FIG. 5 is a diagram showing in more detail the structure of a flow path and a branch flow path for supplying air to the air chamber and the auxiliary chamber.
As shown in FIG. 5, the discharge flow path 50a for communicating the air chamber 48 and the central auxiliary chamber 52 is manufactured to have a gradually narrower diameter from the inlet 50b side to the outlet 50c side. This is because the air chamber 48 has a cushioning force by delaying the discharge speed of the air discharged from the air chamber 48 to the central auxiliary chamber 52.
Further, the branch flow path 56a that connects the central auxiliary chamber 52 and the side auxiliary chamber 54 is also made to have a gradually decreasing diameter from the inlet 56b side to the outlet 56c side. This is because the discharge speed of the air discharged into the chamber 54 is delayed, and the remaining pressure remains as the remaining pressure, thereby creating an air chamber and having a cushion portion.
In addition, a spot heat fusion part 60 is fused and formed in the central auxiliary chamber 52. The spot heat fusion part 60 is means for stably adjusting the discharge speed of air discharged to the central auxiliary chamber via the discharge flow path 50a. That is, the air that has passed through one discharge flow path is divided into two ways via the spot heat fusion part and stored in the central auxiliary chamber, so that the air discharge speed can be stably adjusted. it can. Here, to stably adjust the air discharge speed means to delay the air discharge speed as much as possible.
On the other hand, the spot heat fusion part 60 can adjust the air discharge speed again according to the fusion position, but specifically, the spot heat fusion part is formed in the state close to the outlet 50c side of the discharge flow path 50a. As a result, the discharge pressure rises while the outlet 50c of the discharge flow path 50a becomes narrow, so that the discharge speed of air can be stabilized. On the contrary, the spot heat fusion portion 60 is connected to the discharge flow path 50a. If it is formed far away from the outlet 50c side, the outlet 50c of the discharge channel 50a becomes wider, so that the air discharge speed can be increased.
On the other hand, the spot heat fusion part 62 is also fused and formed in the side auxiliary chamber 54. The spot heat fusion part 62 is means for stably adjusting the discharge speed of air discharged from the central auxiliary chamber 52 to the side auxiliary chamber 54 via the branch flow path 56a. That is, the air that has passed through the branch flow path 56a is divided into two ways through the spot heat fusion part 62 and stored in the side auxiliary chamber 54, thereby delaying the air discharge speed as much as possible. it can. Moreover, the discharge speed of the air can be adjusted by forming the fusion position of the spot heat fusion part 62 close to or far from the outlet 56c side of the branch flow path 56a.
As a result, the present invention is divided into two types in the process in which the air exhausted through the single exhaust flow path 50a through the spot heat fusion parts 60, 62 flows into the central auxiliary chamber 52, and The air stored in the central auxiliary chamber 52 via the branch flow path 56a has a discharge structure in which the air is divided into four ways and flows into the side auxiliary chamber 54, thereby stabilizing the air discharge speed. Can be adjusted.
Hereinafter, the operation of the ventilated footwear in which the cushion and the ventilation device according to the present invention are installed will be described with reference to FIGS. 3 to 7B attached.

First, the manufacturing process of the cushion and ventilation device 20 corresponding to the main configuration of the present invention will be described.
As shown in FIG. 3, the cushion and ventilation device 20 is manufactured by heat-sealing the connecting portion with high frequency in a state where the air pump 22 and the air tube 38 are separately manufactured.
First, the sponge 32 and the elastic member 36 are sequentially placed on the lower sheet 26, and then the upper sheet 24 is stacked thereon to manufacture the air pump 22.
Next, after manufacturing the air tube 38 having the connecting pipe 44 and the air chamber 48 through the previous process, the inlet 44 a of the connecting pipe 44 of the air tube 38 is placed between the air discharge pipe 30 of the air pump 22. After the portion is inserted, the peripheral surfaces of the upper sheet 24 and the lower sheet 26 of the air pump 22 are heat-sealed at a high frequency, and the air tube 38 and the air pump 22 are fused to each other. To manufacture.
At this time, in the process of fusing the air pump 22 and the air tube 38 through the non-conductor 46 fitted into the inlet 44a of the connecting pipe 44 of the air tube 38, the inlet 44a of the connecting pipe 44 is melted together. It can be worn and kept open without being closed.
On the other hand, the action of the footwear provided with the cushion and the ventilation device 20 manufactured as described above will be described.
When the pedestrian starts walking with the cushion and the ventilation device 20 installed on the footwear, as shown in FIGS. 6A and 6B, the sole side (heel) first comes into contact with the ground, and in this process the air pump 22 contracts and air is sucked through the suction hole 26a. At this time, when the suction of air is completed, the air pump 22 can quickly return to the initial state via the sponge 32 and the elastic member 36 that elastically supports the sponge 32.
Next, the air sucked into the air pump 22 is supplied to the air discharge pipe 30 and then flows into the connection pipe 44 of the air tube 38 inserted between the air discharge pipes 30. At this time, the non-conductor 46 fitted into the inlet 44a of the connecting pipe 44 functions as a check valve, and allows air to pass through only in one direction. That is, as shown in FIG. 7A and FIG. 7B attached, the upper and lower surfaces of the non-conductive body 46 fitted into the inlet 44a of the connecting pipe 44 due to the pressure of the air supplied to the air discharge pipe 30, A gap K is generated, and air flows into the connecting pipe line 44 through the gap K. When the inflow of air is completed, the upper and lower surfaces of the non-conductor 46 are brought into close contact with the connection pipe 44 again, thereby preventing the backflow of air. The air that has flowed into the connection pipe 44 is stored in the air chamber 48 thereafter.
Next, as shown in FIG. 4, when the front part of the foot of the pedestrian (the sole of the foot) comes into contact with the air chamber 48, the cushioning force is exerted by the pressure of the air stored in the air chamber 48, Reduces the impact on the soles of pedestrians.

At the same time, the air stored in the air chamber 48 flows into the central auxiliary chamber 52 via the discharge flow path 50a by the pressure of the sole of the foot, and then the side auxiliary chamber 54 via the branch flow path 56a. And then flows into the footwear through the outlet 58 formed in the side auxiliary chamber 54. That is, the air stored in the air chamber 48 passes through the plurality of auxiliary chambers 48a (from the central auxiliary chamber 52 to the side auxiliary chamber 54) via the plurality of discharge channels 50a and the branch channels 52a. By flowing into the interior, the air discharge time is delayed, and the cushioning force of the air chamber 48 can be maintained for a long time.
In addition, as shown in FIG. 5, the discharge channel 50a and the branch channel 56a are made narrower in diameter from the inlet side to the outlet side, thereby delaying the air discharge time and increasing the pressure to stabilize In this structure, the cushioning force of the air chamber 48 can be delayed more effectively.
On the other hand, the air stored in the air chamber 48 through the discharge flow path 50a and the branch flow path 56a as described above is discharged to the central auxiliary chamber 52 and the side auxiliary chamber 54, and the central auxiliary chamber 52 and the side support. The spot heat fusion parts 60 and 62 fused and formed in the chamber 56 adjust the outlet 50c of the discharge channel 50a and the outlet 56c of the branch channel 56a, thereby adjusting the air discharge time.
FIG. 8 is a plan view showing a cushion and a ventilating apparatus according to another embodiment of the present invention. The same reference numerals are used for the same components, and a detailed description thereof will be omitted.
The cushion and ventilation device 20a of another embodiment is provided with an air pump 22 at the rear, and an air tube 38 is provided with a second air chamber 49 and an air chamber 48 in the air discharge pipe 30 provided in the air pump 22. Consists of.
The second air chamber 49 is formed so as to be located at the arch portion of the sole of the foot, that is, the recessed portion of the sole of the foot, and when the second air chamber 49 is expanded by the inflow of air, It is preferable to support the palm of the foot.
Between the air discharge pipe 30 and the second air chamber 49, a non-conductor 46 that allows air to pass in only one direction is formed. Between the second air chamber 49 and the air chamber 48, a second A discharge channel 49a is formed.
The second discharge channel 49a is preferably formed to have a gradually narrower diameter from the inlet 49b to the outlet 49c. This is because the second air chamber 49 has a cushioning force by delaying the discharge speed of the air discharged from the second air chamber 49 to the air chamber 48.
Although the operation state of the cushion and the ventilating device of the other embodiment configured as described above will be described, the same configuration has the same operation state, so the description of the operation will be omitted.
First, when the pedestrian starts walking with the cushion and the ventilation device 20a installed on the footwear, the sole side (heel) first touches the ground, and in this process, the air pump 22 inhales external air while contracting, The sucked air flows into the air tube 38 through the air discharge pipe 30.

The air tube 38 is composed of a second air chamber 49 and an air chamber 48, and the air discharged from the air discharge pipe 30 allows air to flow in only one direction by the non-conductor 46, so that the second The air chamber 49 expands.
The air flowing into the second air chamber 49 flows into the air chamber 48 via the second discharge channel 49a. The second discharge channel 49a becomes narrower as it goes from the inlet 49b to the outlet 49c. Since it is formed with a diameter, it delays the air discharge time and supports the palm of the sole of the foot along with the cushioning force.
Further, the air discharged through the second discharge flow path 49a of the second air chamber 49 flows into the air chamber 48, and as described above, flows into the auxiliary chamber through the air chamber 48, It is discharged outside through a discharge port formed in the auxiliary chamber.
