The cushion function is to improve the feeling of landing by absorbing the shock applied to the heel of the shoe that comes into contact with the ground first when walking. That is, by cushioning the shock transmitted from the heel to reduce the fatigue that the pedestrian feels. Conventional techniques for cushioning function include manufacturing soles of shoes such as mid-soles and out-soles using elastic materials such as polyurethane or synthetic rubber, or a plurality of coils in the heel of shoes. The method of using elasticity, such as injecting the spring vertically, was mainly used. However, in the case of using the stretchable material, a lot of manufacturing costs are required, and the elasticity of the stretchable material gradually decreases over time. In addition, the method of incorporating the coil spring in the heel can not expect a sufficient cushioning function because the stretch distance of the spring is limited, there is a problem that the manufacturing of the shoe is difficult to have a complicated structure.

The air circulation function is to improve the fit by removing the moisture present in the shoes. That is, the air circulation function to prevent the growth of various bacteria by drying the moisture caused by the sweat generated from the foot of the pedestrian, and to prevent skin diseases such as foot odor or athlete's foot. Conventional techniques for the air circulation function is mainly to manufacture the upper of the shoe using a breathable material.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, the same reference numerals are used for the same components as much as possible even if they are shown in different drawings.

First, with reference to the accompanying drawings will be described the configuration of a functional shoe having a cushion and an air circulation function according to an embodiment of the present invention.

1 is a side view showing the insole, the midsole and the outsole to show the main part of the functional shoe having a cushion and air circulation function according to an embodiment of the present invention, Figure 2 is a folding elastic member of FIG. It is an exploded perspective view shown. Functional shoe 100 having a cushion and air circulation function according to an embodiment of the present invention is large insole 110, midsole 120, outsole 130, foldable elastic member 140 as shown in FIG. , The sealing member 150 and the air passage (160).

Insole (110) is a part in contact with the sole of the pedestrian, aka insole is called. Upper 102 is bonded to the upper surface of the insole 110 along the circumference. In addition, the insole 110 may be attached to the upper surface of the midsole 120 or may be positioned on the upper surface of the midsole 120 to be replaceable.

On the other hand, the insole 110 contains an inorganic material that emits far infrared rays. Far infrared rays are widely known to be effective in penetrating the human body to improve blood circulation through heat action, bactericidal action, prevention and improvement of diabetic disease. In addition, it is known to have effects such as deodorization, dehumidification, and air purification. Inorganic materials that emit such far infrared rays include natural rock, such as MgO, SiO ₂ and ZrO ₂ , ceramics, charcoal, jade, and germanium. Such a far infrared ray emitting material may be made of fibers, which may be used for the manufacture of the insole 110.

In addition, the insole 110 is preferably anion treatment to release the anion. Negative ions are known to have effects such as purification of blood, improvement of blood circulation, activation of cells, fatigue recovery, and pain relief by ionizing and alkalizing mineral components such as calcium, sodium, and potassium in blood.

Midsole 120 is located between the insole 110 and the outsole 130, made of a material such as polyurethane, synthetic rubber has a cushion function in itself. As shown in FIG. 1, the midsole 120 has a tunnel portion 122 formed at an opening at a rear end thereof. The tunnel portion 122 has a lower surface 122a formed in parallel with the ground, and an upper surface 122b that forms a predetermined angle α with the lower surface 122a. At this time, it is preferable that the predetermined angle (alpha) of the tunnel part 122 is 10 degrees-30 degrees.

On the other hand, the midsole 120 is formed to be curved in a form in which the front side and the rear side is spaced apart from the ground to enable the cloud movement of the shoe 100 when walking as shown in FIG.

In addition, the midsole 120 is formed with a reinforcing member 170 for maintaining the shape of the midsole 120 therein. The midsole 120 has a problem in that its elasticity decreases due to repeated deformation, and thus the original recovery capability is lowered. Therefore, the reinforcing member 170 is improved by using a high elastic material such as synthetic rubber, or by inserting a hard material such as hard synthetic resin into the midsole 120. According to the present exemplary embodiment, the reinforcing member 170 may include a first reinforcing member 170a formed in the midsole 120 and a second reinforcing member 170b formed under the tunnel portion 122, as shown in FIG. 1. Consists of The first reinforcing member 170a reinforces the front side of the midsole 120, and the second reinforcing member 170b supports and reinforces the folding elastic member 140. As such, the reinforcing

members

170a and 170b reinforce the midsole 120 in a double manner, thereby preventing a segmentation phenomenon in which the center portion of the midsole 120, that is, the front side of the tunnel portion 122 is bent. Therefore, the shape of the midsole 120 is kept constant during the cloud movement of the shoe 100, it is possible to smooth the cloud movement.

The outsole 130 is joined to the lower surface of the midsole 120 as a part in contact with the ground. At this time, the outsole 130 is formed with a tread (132) made of a plurality of grooves or protrusions, to prevent the slip.

Foldable elastic member 140 is inserted into the tunnel portion 122 described above serves to absorb the impact of the pedestrian load. According to an embodiment of the present invention, the folding elastic member 140 has a plate-shaped support portion 142 for supporting the lower surface 122a of the tunnel portion 122 as shown in FIGS. 1 and 2, and the tunnel portion. The plate-shaped rotating part 144 which supports the upper side surface 122b of 122 is provided. In addition, the support part 142 and the rotation part 144 are hinged by the rotation shaft 145. At this time, the rotation shaft 145 is fixed by the rotation shaft fixing member 145a. In addition, the elastic part 146 is installed on the rotation shaft 145 so as to be positioned between the support part 142 and the rotation part 144. As shown in FIG. 2, the elastic portion 146 includes a pair of torsional coil springs 146a, a first extension portion 146b and a second shape having a “C” shape extending from the torsional coil spring 146a, respectively. Extension 146c. The first extension part 146a and the second extension part 146c form a predetermined angle α as described above, and support the support part 142 and the rotating part 144, respectively. At this time, since the support part 142 supports the lower surface 122a of the tunnel part 122 formed in parallel with the ground, the pivoting part 144 is folded to the relatively fixed support part 142. Therefore, when the load is applied to the upper surface of the pivoting elastic member 140, the pivoting portion 144 is elastically folded by the elasticity of the elastic portion 146.

Alternatively, the folding elastic member 140 may be a leaf spring 140 "having the support 142" and the pivot 144 "integrally, as shown in Fig. 3. That is, the support 142" and It is elastically folded by the elasticity of the part which connects the rotation part 144 ".

As described above, the folding elastic member 140 may be designed by adjusting the elastic modulus of the torsion coil spring 146a and the leaf spring 140 "in consideration of the fit of the shoe 100, the impact absorption efficiency, and the like. The same foldable elastic member 140 has the advantage of being easy to manufacture in a simple structure, and also because the foldable elastic member 140 is deformed as large as a predetermined angle (α) can significantly improve the impact absorption efficiency compared to the prior art. .

The sealing member 150 is manufactured in a thin film form using a stretchable material and serves to seal the tunnel portion 122. As shown in FIG. 1, the sealing member 150 is inserted into the tunnel portion 122 while completely surrounding the outer circumference of the folding elastic member 140. Alternatively, it is also possible to seal the tunnel portion 122 by bonding the sealing member 150 to the tunnel portion 122 into which the folding elastic member 140 is inserted.

The air flow path 160 serves to communicate the air inside the shoe 100 with the tunnel portion 122. According to this embodiment, the air flow path 160 uses a hose. One end of the air passage 160 is located at the front side of the insole 110 to communicate with the inside of the shoe 100, and the other end of the through-hole 143 formed in the support part 142 of the folding elastic member 140. In communication with the tunnel portion 122 through.

The

check valves

162 and 164 are small valves using thin films, and serve to flow air in one direction. According to one embodiment of the present invention as shown in Figure 1 is provided with a check valve 162 for discharging at one end of the air flow path 160 located in the front side of the insole 110, the sealing member 150 One side is provided with a suction check valve (164). This ventilates the inside of the shoe 100 by continuously supplying air into the shoe 100 by the pumping action of the tunnel 122.

Alternatively, one end of the air passage 160 may be provided with a suction check valve 164, and one side of the sealing member 150 may be provided with a discharge check valve 162. This continuously inhales the air in the shoe 100 and discharges it to the outside to ventilate the inside of the shoe 100.

Hereinafter, with reference to the accompanying drawings will be described the operation of the functional shoe 100 having a cushion and the air circulation function according to an embodiment of the present invention.

First, the cushion function and rolling motion of the present invention will be described.

When walking and wearing the shoe 100 according to an embodiment of the present invention, the rear side of the shoe 100 first touches the ground. At this time, the load of the pedestrian is applied to the heel, and the foldable elastic member 140 inserted into the tunnel portion 122 is elastically folded to efficiently absorb the shock transmitted to the heel, thereby resulting in a feeling of landing. Greatly improved. At this time, the shape of the midsole 120 and the outsole 130 is curved in the form in which the front and rear sides are spaced apart from the ground, so that soft landing is possible, and the landing surface of the shoe 100 has a large landing area. There is a decreasing effect.

Next, after landing, the pedestrian's load is moved to the toe. In addition, the outsole 130 of the shoe 100 has a cloud movement along the ground, and the impact that is not absorbed by the foldable elastic member 140 is absorbed by being continuously dispersed. In addition, since the load of the pedestrian gradually moves to the toe along the curved surface of the outsole 130, smooth and natural walking is possible. The elastic member 140, which was folded in this process, is unfolded again by the elastic restoring force to generate a repulsive force, and has an effect of pushing the pedestrian's foot forward. This enables efficient walking.

Next, the air circulation function of the present invention will be described.

When walking and wearing the shoe 100 according to an embodiment of the present invention, when the folding elastic member 140 is folded at the time of landing, the tunnel portion 122 of the midsole 120 is contracted. At this time, the air inside the tunnel portion 122 is pumped and supplied into the shoe 100 through the discharge check valve 162 through the air flow path 160. When the load applied to the foldable elastic member 140 is released, the tunnel portion 122 expands to its original state while being unfolded. At this time, air is introduced through the suction check valve 164 provided on one side of the sealing member 150. As this process is repeated, fresh external air is continuously introduced into the shoe 100, and thus, an efficient air circulation is achieved, thereby achieving a comfortable wearing feeling. In addition, when the check valve 164 for suction is provided at one end of the air flow path 160 and the check valve 162 for discharge is provided at one side of the sealing member 150, in the opposite case, the humid air inside the shoe 100. By continuously inhaling the discharge to the outside it is to circulate the air inside the shoe (100).

On the other hand, the insole 110 is to effectively discharge far infrared rays with the air circulation made in the shoe 100 to perform deodorization, dehumidification, antibacterial effect, etc., further improves the fit. In addition, there is an advantage that can improve the foot health of the wearer, such as improved blood circulation, prevention and improvement of diabetic diseases, pain relief through far infrared rays and anions emitted from the insole 110.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications are It is obvious that it belongs to the scope of the appended claims.
