When described in more detail on the basis of the accompanying drawings the preferred embodiment of the present invention.

1 to 3, the present invention includes a blower tube 20 installed below the shoe 11 inside 11.

Since the blower tube 20 is manufactured by a rubber material having elasticity, the upper surface portion 21 and the lower surface portion 22 having elasticity are integrally formed to form an air chamber between the upper and

lower surface portions

21 and 22. 23) by being configured to have a pressurizing force applied from the outside to the blower tube 20 itself is compressed and is made in a state that will have the elasticity to be restored to its original state when the pressing force is lost.

In addition, the rear side of the blower tube 20 is configured to include an expansion air chamber 231 having a larger volume and communicating with each other than the air chamber 23 on the ship side. Preferably, the expanded air chamber 231 has a volume about 2-3 times larger than that of the air chamber 23.

And the side of the upper surface portion 21 of the blowing tube 20 is provided with a blowing means 24 to allow the air of the air chamber 23 to be blown into the shoe (11) inside (11).

The air blowing means 24 is made to include a plurality of air holes 241 on the side of the upper surface portion 21 of the air blowing tube 20 in one embodiment.

Therefore, when the blower tube 20 is compressed, the air of the air chamber 23 is blown into the shoe 10 inside 11 through the plurality of blower holes 241.

On the other hand, Figures 4 and 5 show the blowing means 24 'of another embodiment.

Referring to FIG. 4, the blowing means 24 ′ of the other embodiment cuts the upper surface portion 21 side of the blowing tube 20 in a cross shape so that a plurality of cross cutting lines 242 are formed.

Therefore, the cross cut line 242 is provided with several opening and closing ends 243 in four directions.

Therefore, when the shoe 10 is lifted from the ground when no pressure is applied to the blower tube 20, each opening / closing end 243 of the blower tube 20 as shown in FIG. Parallel to the upper surface portion 21 is in a state in which the air chamber 23 is closed.

However, when the shoe 10 comes into contact with the ground during walking, pressing force is applied to the blower tube 20, so that the air pressure in the air chamber 23 is exhausted to the outside, whereby the exhaust pressure is increased. It is in a state acting on the inner surface portion of the blowing tube (20).

At this time, the air having the exhaust pressure to escape the air in the air chamber 23 pushes the opening and closing end 243 in the upper direction, so that several opening and closing ends 243 are upper as shown in FIG. The opening hole 244 is formed while being bent in a direction so that the air in the air chamber 23 is blown into the shoe 10 inside 11 through the opening hole 244.

When the shoe 10 is lifted again from the ground by continuous walking, the compressed blower tube 20 is expanded as shown in FIG. 5 (a), so that the upper surface portion 21 is moved up to its original position. In this case, as the upper surface portion 21 is moved upward, as the external air is pushed up and down the open end (243) lifted upwards, the open and close end (243) is moved downwards and the open and close end (243) is blown tube Parallel to the upper surface portion 21 of the (20) is to close the air chamber (23).

That is, when the shoe 10 is lifted from the ground during walking, the opening and closing end 243 acts as a closing action to block air from the inside of the shoe 10 from entering the blower tube 20. When 10) lands on the ground, the opening / closing end 243 is opened so that the air in the air chamber 23 of the blower tube 20 is blown into the shoe 10 inside 11. Will be.

Therefore, in the case of the blowing means 24, which is the blowing hole 241, when the blowing tube 20 is inflated, the air in the shoe 11 inside 11 is blown through the blowing hole 241 even though a small amount of air. In the case of the blowing means 24 ′ having the cross-cut 242, the opening and closing end 243 may be inflated when the blowing tube 20 expands. The air blowing means 24 having the cross-cutting cutting line 242 in the present invention because the closing action is to prevent the air in the shoe 11 inside 11 to be sucked into the air chamber 23 of the blower tube 20. ') Is preferably employed.

Referring back to Figures 1 to 3, it is configured to have a suction hole 31 at the rear of the lower surface portion 22 of the blower tube (20).

In addition, the present invention is provided with a backflow prevention means 30 for blocking the air of the air chamber 23 introduced into the suction hole 31 back flow through the suction hole 31 again.

The reverse flow prevention means 30 of the embodiment, the fixed end portion 32a of one side is attached to the inner surface of the lower surface portion 22 of the blower tube 20, and the free end portion 32b of the other side opens and closes the suction hole 31. It is comprised by the valve seat 32 to make.

The valve seat 32 has a fixed end portion 32a indicated by a hatched portion in FIG. 3 attached to one side of the suction hole 31 by fixing means such as an adhesive, and the free end portion 32b is a suction hole 31. It is to be covered close to the top.

Therefore, when the outside air enters the air chamber 23 through the suction hole 31, the free end 32b of the valve seat 32 is lifted upward as shown in the phantom line in FIG. By the opening action to be opened) is the external air is introduced into the air chamber 23 through the suction hole (31).

However, when the air in the air chamber 23 tries to escape again through the suction hole 31, the air to be escaped through the suction hole 31 in the air chamber 23 pushes the free end 32b. Since the free end 32b is in close contact with the suction hole 31 to block the air, the air introduced into the air chamber 23 through the suction hole 31 escapes to the suction hole 31 again. Because of this, backflow is prevented beforehand.

6 and 7 show a non-return means 30 'of another embodiment according to the present invention.

Referring to FIG. 6, the backflow prevention means 30 ′ of the other embodiment includes a body 33 attached to the lower surface portion 22 of the blower tube 20, and a flow hole inside the body 33. 34).

In addition, the upper and lower portions of the flow hole 34 to have a vent hole 35 and the suction hole 31, respectively, in the flow hole 34, the bowl 36 for opening and closing the suction hole 31 It is built.

In addition, the outer periphery of the vent hole 35 is configured such that a plurality of anti-shielding protrusions 37 protrude as shown in FIG. 7 and a vent 38 therebetween.

Therefore, in normal times, the bowl 36 is in a state in which the suction hole 31 is blocked by its own weight to shield the suction hole 31 as shown in the solid line of FIG. As the bowl 36 rises by an input, external air flows into the suction hole 31.

At this time, the rising bowl 36 is in contact with the shielding projection 37 and is no longer raised and is stopped so that the outside air introduced through the suction hole 31 is vented between the shielding projections 37. It is introduced into the air chamber 23 of the blower tube 20 through the furnace 38 and the vent hole 35.

However, as the blower tube 20 is compressed, when the air in the air chamber 23 is pushed into the vent hole 35, the bowl 36 is moved downward in the direction of the suction hole 31. Bowl 36 is to shield the suction hole 31, thereby preventing the backflow of the air in the air chamber 23 through the suction hole 31 is prevented again.

Referring back to Figures 1 to 3, the present invention is provided with an elastic member 40 in the air chamber 23 in order to forcibly expand the tail portion of the air chamber 23 of the blower tube (20).

The elastic member 40 is preferably a coil spring. However, since the resilient member 40 only needs to be forced to expand the rear portion of the air chamber 23, other types of resilient members may be employed in some cases.

Therefore, the present invention is provided with an expansion air chamber 231 extending in the rear portion of the air chamber 23 of the blower tube 20 and the elastic member 40 is embedded therein.

At this time, the elastic member 40, as shown in Figure 8 so that both ends are fixed to the inner surface of the blowing tube 20, respectively by the fixing pad 41. In some cases, however, it may be fixed using a separate spring bracket 42 as illustrated in FIG. 9.

That is, as an example, the installation of the elastic member 40 in the expansion air chamber 231 is to cut a part of the lower surface 22 of the blower tube 20 as shown in FIG. 9 and to both sides of the separate tube member 20a. Attaching the spring bracket 42 with the elastic member 40 and the valve seat 32 installed therein, and then inserting the upper spring bracket 42 into the upper surface 21 by inserting it into the blower tube 20. In addition, the inner surface of the lower surface portion 22 can be attached to the tube member 20a. However, the present invention is not limited thereto, and the elastic member 40 may be embedded by various other methods.

On the other hand, the present invention is provided with an air induction path 50 for inducing external air to be sucked under the backflow prevention means 30 and the suction hole (31).

The air induction path 50 is composed of a guide member 51 having elasticity such as rubber as shown in Figure 1 attached to the lower rear portion 25 of the blower tube (20).

In addition, the present invention includes an intake pipe 60 connected to the air induction path 50.

The intake pipe 60 is installed to stand up so as to be supported in the after-wearing member 12 of the shoe 10 as shown in FIG. Reference numeral 61 denotes a through hole that is to be drilled through the post-wear member 12. This case is preferable when the present invention is manufactured to be completely mounted on the shoe 10 at the time of manufacturing the shoe 10.

However, according to the present invention, as shown in the solid line in FIG. 10, only a part of blowing outside air into the shoe 10 is separately manufactured and inserted into the shoe 10 in the finished state 11. It can also be employed.

In this case, such as adhesive or double-sided tape (not shown) on the inner surface of the after-wear member 12 in the state in which the skin member 62 such as cloth or leather is attached to the outer surface of the intake pipe 60 as shown in FIG. It can also be used to attach. In this case, when the intake pipe 60 is made of a soft material, the intake pipe 60 may be attached to the inner surface of the rear wear member 12 without the skin member 62 alone.

Therefore, the operation of the present invention will be described with reference to FIGS. 11 and 12, which are illustrated only by main components in a state in which the air blowing means 24 and the backflow prevention means 30 according to the embodiment of the present invention are employed.

11 shows the main configuration of the shoe 10 when wearing it and landing on the ground (not shown) when walking.

Therefore, since the first contact with the ground from the heel of the shoe, as shown in Figure 11 (a) at this time, the foot hindgatch (Fb) by the weight first presses the rear end of the blowing tube (20).

Therefore, the rear end portion of the blower tube 20 is pressed flatly so that the elastic member 40 is compressed and the air in the expansion air chamber 231 presses the free end 32b of the valve seat 32 so that the suction hole ( By closing 31, the air in the air chamber 23 does not escape to the suction hole 31.

In addition, as the expansion air chamber 231 of the blower tube 20 is pressed flatly, the air moves forward to the front part through the blower hole 241 as the air moves forward. Will be blown.

And when it is completely landed on the ground as shown in Fig. 11 (b) the foot gum (Fb) is pressed in the expansion air chamber 231 of the blowing tube 20, the front gum Fa (Fa) is blown tube 20 As the pressurized side portion of the pressurized side is pressed, the air blowing tube 20 of the side portion is compressed, so that the air remaining in the front air chamber 23 passes through the air blowing hole 241 to the front toe gum portion Fa. It will be blown secondarily.

Next, when the foot (F) is lifted as the user continues to walk, first, as shown in FIG.

Therefore, the front portion of the blower tube 20 is further pressed by the front toe gum (Fa) while the foot toe gum (Fb) located on the rear side of the blower tube 20 is lifted up, thus being compressed and in close contact. Since the air chamber 231 is opened by the elasticity of the elastic member 40, the expansion air chamber 231 is expanded.

In addition, the guide member 51 compressed under the expanded air chamber 231 is also in a state of being unfolded by its own elasticity.

Therefore, as the expansion air chamber 231 and the induction member 51 are opened, suction force is generated, and as a result, external air is sucked through the intake pipe 60 and expanded through the air induction path 50 and the suction hole 31. External air is primarily suctioned into the air chamber 231.

In addition, at this time, the free end 32b of the valve seat 32 is lifted by the external air sucked, thereby allowing the external air to be sucked into the suction hole 31.

In addition, since the expansion air chamber 231 is rapidly expanded by the elasticity of the elastic member 40, a strong suction force is generated, thereby sucking the outside air quickly.

At this time, the air blowing hole 241 is a very small hole, and because the small hole is not partly blocked by the front toe gum (Fa), and the side portion of the blower tube 20 is pressed by the toe gum (Fa). Since the air is sucked in through the air blowing hole 241 can be said to be very small, it can be ignored.

Next, when the foot F is completely lifted up in the air by continuing to walk, the pressing force of the side portion of the blower tube 20 pressed by the front toe gum Fa is released as shown in FIG. 12 (b). Since the side portion of the blower tube 20 is due to its elasticity, the upper and

lower portions

21 and 22 are separated from each other and are in a state of being unfolded in the original state.

Therefore, as the blower tube 20 has a secondary suction force, a state in which external air flows into the blower tube 20 secondarily through the intake pipe 60 and the air induction path 50 and the suction hole 31. Becomes

Therefore, in the present invention, when lifting the foot (F) when walking, the external air is sucked into the entire air chamber 23 including the expansion air chamber 231 of the blowing tube 20, and the foot ( F) When stepping on the ground, the fresh air outside the shoe (10) is repeatedly operated since the outside air sucked into the blower tube 20 continues to be repeatedly operated whenever the air is blown into the inside of the shoe 10. ) Is continuously blown into the interior (11).

And the present invention is characterized in that when blowing abundant outside air reliably blows into the shoe (10) inside (11).

In order to facilitate the understanding of the present invention, in the past, not only the external air receiving volume that can be accommodated by the blower tube was small, but also because the compressed blower tube 20 was restored to be unfolded only by its elastic force. For example, when the air blower tube 20 is not fully opened or the speed of unfolding is slowed when walking or running fast, the suction force is weak and the speed of sucking external air is slowed down, so that the external air cannot be sucked enough. Only a small amount of external air was supplied into the interior 11.

However, since the present invention includes the expansion air chamber 231, the blower tube 20 can accommodate a large amount of external air, and the expansion air chamber 231 is reliably expanded by the elastic member 40 and is also strong. Since a large amount of external air can be sucked by generating a suction force, it is possible to blow abundant external air into the shoe 10 inside 11 even during a quick walk or a run.

Therefore, in the past, the ventilation efficiency was low in the active shoes such as sneakers, sports shoes or military boots due to the insufficient amount of external air blowing, but the present invention reliably blows the rich outside air even in the active shoes such as sneakers, sports shoes and military boots. It is possible to improve the ventilation efficiency is very high.

In addition, since the blower tube 20 is installed in the upper portion of the sole 10 of the shoe 10 as shown in FIG. 1, the height of the expanded air chamber 231 can be increased, so that the shoe 10 is placed on the ground. Since it is possible to reliably absorb the walking impact force generated while touching, it also serves as a significantly improved buffering effect.

In particular, in the present invention, since the air induction path 50 is formed by the induction member 51 having the elasticity at the rear of the blowing tube 20, the induction member 51 is first placed when the hind paw Fb lands on the ground. While closely contacting the lower surface portion 22, the first buffering action, and then the secondary buffering action that absorbs the walking impact force while the air and the resilient member 40 accommodated in the expansion air chamber 231 is compressed. do.

Therefore, the pedestrian impact force of the hind gingival (Fb) portion, which receives more pedestrian impact force when walking, is relatively improved compared to the former, and thus will have a very improved buffering effect.

And since the present invention is provided on the sole 13 of the shoe 10, as shown in Figure 1 has a sole 13 with a protective metal plate 14 and easily ventilated safety shoes or boots or boots Adoption is possible.

Therefore, the present invention is to provide a shoe 10 that can be easily employed in all shoes regardless of the type of shoes, but can reliably blow abundant outside air in the shoe 11 inside (11).

Although the present invention has been illustrated and described by some embodiments, it is not intended to be limited thereto, and the present invention may be modified in various forms by those skilled in the art to which the present invention pertains. It is self-evident that it must be widely protected unless it deviates.
