Description

Ventilated shoes using semicircular leaf springs

The present invention relates to a ventilated shoe that allows air to be blown inside a shoe such as shoes or boots, and more particularly, a semi-annular leaf spring improved to allow ventilation and comfortable walking by allowing natural walking while being ventilated. It relates to a gout shoe using.

In general, a lot of ventilation shoes have been developed in the past, but in general, the ventilation volume is insufficient or difficult to manufacture, the price of the product is not practically desirable or impossible to manufacture it is often not released as a real product.

In addition, a ventilated shoe using a spring and a ventilated shoe using a spring are disclosed.

However, the ventilation shoes without the spring is relatively low ventilation, while the ventilation shoes using the spring are relatively unventilated because they do not overcome the disadvantage that the ventilation is relatively high but the walking is not comfortable. .

That is, when the spring is used, it is more preferable to use the spring for the ventilation shoes because the ventilation action is more reliably performed by the spring force.

However, the conventional spring-ventilated shoes simply use a coil spring, and since the coil spring is adopted, the sole of the foot is sore or injured, especially when walking or running quickly. As the case occurs, it is accompanied by a problem that can not be released as a product.

In the prior art, the ventilation shoes such as the Republic of Korea Utility Model Publication No. 20-1985-0008316 is the ventilation structure is built in the coil spring in the front heel in the ventilation structure, but the ventilation efficiency because it is not pressurized well in front of the coil spring when walking This is accompanied by a disadvantage of deterioration.

In addition, the ventilation shoes, such as the Republic of Korea Utility Model Publication No. 20-1990-0001782 has a disadvantage that the air is drawn in only inside the shoe because a plurality of coil springs are built in the ventilation structure to be ventilated. In the case of new utility model publication No. 20-1993-0005060, the coil spring is built into the rear of the shoe so that the air simply enters and exits.

And as the above-described prior art ventilation shoes with a coil spring is built in the compressed state because the coil spring is compressed so that it is folded in the same state as a vertical column in the state of walking when walking In the state of being in a state of stepping on a rigid vertical column, the sole of the coil spring portion is crushed and is in a state of hurting.

In particular, when you are walking or running fast, the weight of the coil springs in the vertical posture will put more weight on your body. Since the soles of the coil springs are very painful due to the pain, there is a problem that the exercise cannot be continued continuously, and there is a serious problem that the ventilation shoes using the coil springs are not released into the product.

In addition, whenever you put your foot on the ground, such as walking or running fast, you put more weight on the coil spring in a vertical column. Rather, depending on the uneven ground conditions, the weight will be carried in the diagonal direction.

Therefore, when the weight is loaded in a diagonal direction, since the coil spring is formed by winding the wire in the circumferential direction, the wires are slid in the lateral direction and become slipped, thereby causing ankle to be sprained or fall down. .

Since the coil springs are made of iron wires, it is difficult to fix the wire strands or cannot be firmly fixed even if the wire strands are fixed. The elasticity is lost or the coil spring is twisted ankle is a problem such as to sprain the ankle is in a situation that can not be further commercialized.

Therefore, conventionally, the ventilation shoe using the spring does not start as a real product, and only the ventilation shoe without the spring is released as a product and does not overcome the problem that only the ventilation shoe having insufficient ventilation is spread at all.

Applicants have therefore been able to study ventilated shoes that use springs to ensure reliable ventilation, while the soles are not vented, allowing them to continue walking longer and not to suffer ankle injuries.

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

The shoe 1 to which the present invention is practiced can be implemented not only in the boots illustrated in FIG. 1 but also in all the shoes 1 ranging from shoes and sneakers or boots. In the case of long necks such as boots or boots, the zipper 6 may be provided at one side to be easily worn, and the present invention may be implemented in the shoe 1 having the zipper 6.

Therefore, referring to FIG. 1, the present invention provides a blower tube 10 having a air chamber 11 and seated longitudinally from the front heel 3 to the heel 4 of the interior 2 of the shoe 1. Equipped.

In addition, the tube upper surface portion 14 toward the rear end portion 13 of the blower tube 10 is provided with a backflow prevention combined intake means 20 so as to suck air into the air chamber 11.

In addition, the tube top surface portion 14 toward the tube front end portion 12 of the blower tube 10 includes an air discharge means 30 through which air from the air chamber 11 is discharged into the shoe 11.

In addition, the air chamber 11 is forcibly expanded in the air chamber 11 between the tube upper surface portion 14 and the tube lower surface portion 15 toward the rear end portion 13 of the blower tube 10, and the up and down direction It is configured to have a semi-arc plate spring means 40 for elasticity and compression action.

2, the semicircular leaf spring means 40 has a gentle slope arc portion 41 and a steep slope arc portion 42 on the line and the rear end, respectively, and the lower surface of the tube portion 15 on both sides. It is comprised so that it may be provided with the fixed end part 43 fixed to ().

The fixed end 43 is fixed to the lower surface of the tube 43 by an adhesive or other fixing means, and as shown in FIG. 3, the fixed end 43 may be configured to be bent in an outward direction, respectively.

Referring back to FIG. 2, the air discharging means 30 may be formed of discharge holes 31 provided in the tube upper surface portion 14.

However, the air discharge means 30 of another embodiment as shown in Figs. 4 and 5 may be employed.

In this case, as shown in FIG. 4, the tube upper surface portion 14 is cut in the shape of a cross to have a plurality of cross-cut lines 32, and as a result, four open-ended portions 33 are formed in four sides of the cross-cut lines 32. Will be provided.

Therefore, in the state in which the blower tube 10 is not pressurized as shown by the solid line in FIG. 5A, the opening and closing end 33 is in a closed state.

However, when the upper tube portion 14 of the blower tube 10 is pressed downward as shown in the solid line of FIG. 5B, the air in the air chamber 11 is compressed and the opening / closing end portion 33 is closed by the air compression force. As it is bent in the upper direction, the discharge hole 31 'is formed, whereby the air in the air chamber 11 is discharged into the discharge hole 31', and the air is blown into the inside of the shoe 1. .

When the compressed blower tube 10 is in an expanded state as shown in the solid line of FIG. 5A, the tube upper surface 145 moves upwardly as shown in the solid line to open and close the open end ( 33 is drawn to the closed state as shown by the arrow shown in the state that the air in the shoe 2 inside (2) is blocked to prevent inflow into the air chamber (11).

That is, when the shoe 1 is lifted from the ground during walking, the air chamber 11 of the blower tube 10 expands and the opening / closing end 33 is closed so that the air in the shoe 2 inside the shoe 2 is closed. The reverse flow into the air chamber 11 is blocked. On the contrary, when the shoe 1 lands on the ground during walking, the blower tube 10 is compressed and the air in the air chamber 11 is compressed, thereby compressing the air. As the opening and closing end 33 is opened, the discharge hole 31 ′ is generated, and the air in the air chamber 11 is discharged to the discharge hole 31 ′.

And the reverse flow prevention combined intake means 20 of the present invention, as shown in Figure 6, the bolt member 23 each having a flange 21 and the intake hole 22 to press the tube upper surface portion 14 to be fixed And nut members 24, respectively.

Therefore, when the bolt member 23 and the nut member 24 are fastened, the blower tube 10 is pressed and fixed between the flanges 21 provided therebetween. At this time, if the adhesive is applied to the blowing tube 10, which is sandwiched between the flanges 21 to be compressed, it is possible to more surely prevent the air leakage.

In addition, the intake hole 22 of the nut member 24 is configured to be opened and closed by the free end 25b of the open / close sheet member 25 to which the fixed end 25a is fixed to the nut member 24.

However, the inflow preventing combined intake means 20 according to the present invention is not necessarily fixed by fastening the bolt member 23 and the nut member 24, but is fixed to the blower tube 10 by other fixing means in some cases. It can be done.

Therefore, when the shoe 1 lands on the ground at the time of walking, the air blowing tube 10 is compressed, and the air in the air chamber 11 is compressed to open and close the sheet member by the air to be discharged to the intake hole 22. Since the free end 25b of 25 is brought into close contact with the intake hole 22, the intake hole 22 is shielded so that the air in the air chamber 11 flows back to the intake hole 22 and does not escape. Becomes

When the shoe 1 is lifted from the ground during walking, the air chamber 11 of the blower tube 10 is expanded, and a suction force for sucking external air is generated, thereby opening and closing the seat member. The free end 25b of the 25 is sucked as shown in the solid line in FIG. 6 to open the intake hole 22, so that the outside air is sucked into the air chamber 11 through the intake hole 22. do.

And as described above, as the intake hole 22 is opened and closed, the reverse flow prevention action and the intake action are repeatedly performed whenever the shoe 1 is landed or heard when walking.

Therefore, when the blower tube 10 is compressed at the time of walking as shown in the solid line in FIG. 7, the air in the air chamber 11 is discharged through the discharge hole 31 ′ because the intake valve 20 for preventing the flow of back flows. When the blower tube 10 is in a state in which the blower tube 10 is expanded as shown in the phantom line in FIG. 7, the intake valve 20 for the non-return flow acts as an opening action to inhale external air into the air chamber 11. In this way, this action is that the shoe (1) inside the ground (2) is ventilated repeatedly when the shoe (1) is landing on the ground or heard when walking.

On the other hand, when the shoe 1 lands on the ground at the time of walking, the semi-arc leaf type spring means 40 is compressed by the weight as shown in FIG.

At this time, the gentle inclined arc shaped portion 41 and the steep inclined arc shaped portion 42 of the half arc-shaped leaf spring means 40 are pressed by the weight and are in close contact with the tube upper surface portion 14 of the blower tube 10. Since it is straight and flat, the soles do not exhaust or hurt.

In particular, when the shoe (1) when the foot touches the ground mainly landing on the ground from the heel (4) to put more weight on the back of the foot portion to press the semi-circular leaf spring means (40) is gentle slope Relatively steep inclination than the arc 41, the repulsive resilience acts more strongly to the steep slope arc 42, the weight of the weight on the back portion of the foot is first pressed.

Therefore, even when a strong landing force is applied by running, the resilience is strong enough to withstand a strong landing force in the sharp slope arc 42, while also absorbing the strong walking impact force is to buffer.

In addition, when the landing force is first applied to the steep slope arc 42 when landing on the ground, since the bottom surface of the shoe 1 gradually comes to the ground toward the front ridge, the landing force and weight gradually become gentle slope arc It is loaded toward the (41) side and is in a state of being compressed.

Therefore, the landing power and body weight are absorbed while being first absorbed by the steep slope arc part 42 having a relatively strong resilience and then moved to the gentle slope arc part 41 secondly. As in the prior art, it is not concentrated on one point and is dispersed in the half arc type leaf spring means 40, so that the sole is not sore or exhausted.

And when the shoes 1 are lifted from the ground, the half-circular leaf spring means 40 is expanded by elasticity, so that the blower tube 10 is forcibly expanded. In this case, the outside air is reliably provided and the outside air intake means 20 is able to intake a large amount of air.

And the present invention can be provided with the outside air intake means 50 to the outside air intake outside the shoe (1).

The external air intake means 50 is provided with an intake pipe 51 on the inner surface of the rear bent lip 5 of the shoe 1 and attaches a concealment member 52 to the inner surface of the rear bent lip 5 to intake pipe ( 51) is concealed.

In addition, the concealing member 52 allows the lower end portion 54 of the lower fold portion 53 to be attached to the blower tube 10 so that the air passage 55 is disposed between the intake pipe 50 and the intake prevention unit for double back flow prevention. It is configured to have.

The lower side fold 53 is unfolded when the blower tube 10 is compressed so that the lower portion 54 can be smoothly compressed without being detached from the blower tube 10.

Therefore, the present invention is in the state in which the blower tube 10 is expanded to open the backflow prevention combined intake means 20 to suck in the air through the intake pipe 51 and the air passage (55) outside the shoe (1) Atmospheric air is sucked into the air chamber 11 of the blower tube 10 to allow clean outside air to be sucked in, so that fresher air can be blown into the shoe 1 into the inside of the shoe 1 at the time of landing. will be.

And the semi-circular leaf spring means 40 according to the present invention is formed in the vent hole 47 in the portion that is not pressed by the sole at the time of landing as shown in FIG. You can also have a smoother flow.

Fig. 10 shows another embodiment of the half arc leaf spring means 40 according to the present invention.

The half arc-shaped leaf spring means 40 is provided with a gentle slope arc portion 41 and a steep slope arc portion 42 on the line and the rear end, respectively, and the slip end portion 44 at the distal end of the gentle slope arc portion 41. ) Is provided.

In addition, there is provided a fixing member 45 having a long length that is bent in the horizontal direction with the steep inclined arc 42, and fixed to the tube lower portion 15, the slip end 44 is fixed to the fixing member 45 during the compression action It is configured to allow the slip motion in the longitudinal direction from above.

In this case, since the long fixing member 45 is fixed to the bottom surface of the tube 15 so that the fixing area is large, the semicircular plate spring means 40 is more firmly and stably fixed.

In addition, since the slip end 44 is pushed to one side when the semi-arc leaf spring means 40 is compressed by the landing force when walking, as shown in the solid line of Fig. 11, the half arc-shaped leaf spring means The repulsive resilience of 40 does not significantly affect the sole of the foot and is softly compressed to absorb the landing force, thereby preventing the sole of the foot from exhausting or hurting during landing.

Since the landing power and the body weight are absorbed primarily by the steep inclined arc part 42 having a relatively strong repulsive elasticity and then secondarily moved to the gentle inclined arc part 41, the landing power and body weight are increased. As shown in FIG. 7, the semi-arc type leaf spring shown in FIG. 7 described above does not hurt the soles or exhausts by being dispersed in the half arc-shaped leaf spring means 40 without intensively acting at one point as in the related art. Same as the means 40.

On the other hand, Figure 12 shows another embodiment of a semi-arc leaf plate means 40 according to the present invention.

In this case, the semi-arc plate spring means 40 is provided with a gentle slope arc shaped portion 41 and a steep slope arc shaped portion 42 at the front and rear ends thereof, and the slip end portion 44 at the distal end of the gentle slope arc shaped portion 41. The slip end 44 is bent in a horizontal direction with the steep inclined arc 42, so that the slip end 44 in the longitudinal direction on the fixing member 45 is fixed to the tube lower portion 15, the steep arc inclined portion Between the 42 and the fixing member 45 is further provided with a vertical standing portion 46 standing in the vertical direction with the fixing member 45 and not bent by the landing force.

Therefore, as shown by the solid line in Fig. 13, when the half arc type leaf spring means 40 is compressed by the landing force when walking, the slip end portion 44 is compressed while being pushed to one side. The repulsive resilience of the spring means 40 is in a state that absorbs the landing force while being softly compressed without being largely applied to the sole, so that the sole does not exhaust or hurt when landing. The same function as the leaf spring means (40).

However, even when a strong landing force is applied to the semi-arc leaf plate means 40 at the time of landing, the vertical standing portion 46 is not bent or compressed so that the steep arc-shaped portion 42 is compressed so that it does not completely settle down. Since the sharp slope arc 42 has a stronger rebound resilience, a strong landing power and weight is mounted on the shoes (1) at the time of optical illusion, that is, such as sports shoes or sports shoes or hiking shoes or boots ( It is preferable to employ | adopt in 1).

In addition, even when the landing force is applied to the semi-arc plate spring means 40, the vertical standing portion 46 is not bent, so that it may be employed in a so-called tall shoes so that the height is visible.

In the case of the semi-arc leaf spring means 40, which is mainly made of metal, the vertical erecting portion 46 is hardly bent if the metal body is erected in the vertical direction in a state of strong strength. Has a vertical rising portion 46 which is integral with the steep inclined portion 42, and further attaches another vertical member (not shown) to the inner side or the outer side of the vertical rising portion 46 to be folded at the time of landing. It can also be configured not to.

14 to 16 show another embodiment of the half arc leaf spring means 400 according to the present invention.

The embodiment is a side elastic member 410 having a fixed end portion 412 and a gentle slope arc portion 411 is fixed to the tube lower end portion 15 toward the tube rear end 13 side of the blowing tube 10 and fixed Each of the rear side elastic members 420 having the end portion 422 and the steep inclined arc portion 421 is provided to face each other.

In addition, the gentle inclined arc 411 and the steep inclined portion 421 is inserted into each of the arc-shaped elastic connecting member 430 having a flow groove portion 431, respectively, which flows in the longitudinal direction. The arc-shaped elastic connection member 430 is preferably made of a reinforced resin material having a hardness and elasticity.

In this case, when the shoe 1 is lifted from the ground at the time of walking, as shown in FIG. 14, the gentle slope arc portion 411 and the steep slope arc portion 421 of the front and rear

elastic members

410 and 420 are elastically extended, respectively. Since the end portion is in a state that is slightly inserted into the flow groove 431.

Accordingly, when the landing force acts on the semi-arc leaf spring means 400 at the landing in the above state, the whole is compressed as shown in FIG. 16 and the gentle slope arc portion 411 and the steep arc arc portion 421 are respectively flow groove portions. 431 Since the repulsive elasticity of the leaf spring means 400 of the arc-like type is in a state that is significantly offset than the other embodiments described above will be in a state of being pressed into the compressed state is a weaker repulsive elasticity is applied to the state.

That is, when it is compressed by the landing force, the front and rear

elastic members

410 and 420 are compressed. At this time, the gentle slope arc portion 411 and the steep arc arc portion 421 are pushed into the flow groove portion 431 without resistance. Due to the only elastic force of the gentle slope arc 411 and the steep arc arc 421 is repulsive elasticity is acting on the sole is to be compressed without a large repulsion.

In addition, since the landing force and the weight are first absorbed by the steep inclined arc part 421 having a relatively strong repulsive elasticity and then secondarily moved to the gentle inclined arc part 411, the landing power and the weight are As shown in FIG. 7, the semi-arc type leaf spring shown in FIG. 7 does not hurt or exhaust the sole by being dispersed in the half arc-shaped leaf spring means 400 without being concentrated at one point as in the related art. Same as the means 40.

Therefore, the semi-arc leaf spring means 400 of the above embodiment is relatively weak repulsive elasticity is applied at the time of landing is very natural walking is promoted, it is preferable that it is employed in shoes for children or the elderly (1).

In addition, the present invention has a semi-arc plate spring means (40,400) has a gentle slope arc portion (41,411) and a steep arc arc portion (42,421) as described in the embodiments already described to have a relatively strong resilience and landing force and weight After being absorbed primarily by the inclined steep arcs 42 and 421, it is absorbed as it is moved to the gentle slope arcs 411 secondly. Therefore, landing force and weight do not work intensively at one point as in the prior art. It is in the state of being dispersed in the leaf spring means (40,400) of the type so that the sole does not hurt or exhaust, and in the state where the shoes (1) is lifted from the ground of the semi-arc leaf spring means (40,400) Its elasticity is spread by the air blowing tube 10, the rear part is forcibly expanded to act quickly and surely to intake the outside air its features and advantages It is.

Accordingly, the present invention has been shown and described by way of various embodiments, but is not limited thereto, and may be modified in various forms by those skilled in the art, so long as the scope of the claims is not so large. It is self-evident that it should be widely protected.
