In general, athletic shoes, running shoes, jogging shoes, basketball shoes, soccer shoes, tennis shoes, golf shoes, hiking shoes, and industrial safety shoes have significant impact on the ankles and knees when exercising or working. The impact force is transmitted to the ankle or knee whenever the shoe contacts the ground, and the impact force transmitted to the foot or knee causes inconvenience to the user of the shoe and causes fatigue and injury. In particular, middle-aged women and seniors, as well as sneakers, golf shoes or hiking boots, when the normal shoes are worn, the ankles or knees are shocked, causing ankle or knee injury and arthritis.

In order to absorb such impact force, a sneaker is usually equipped with a cushion for absorbing shock, and the cushion for absorbing shock is mounted on the middle sole portion of the back of the shoe, and occurs when a load by the weight of the athlete is applied downward. To absorb shocks. The shock absorbing cushion is made of rubber or sponge but is equipped with an air tube. Sneakers consist of an out sole that forms the bottom of the shoe, a midsole that is attached to the top of the outsole, and an upper sole that forms the top of the shoe. An insole is attached to the upper surface of the midsole inside the shoe to contact the sole of the athlete. Shock absorbing air tubes are mounted on the midsoles of the front and rear portions of the sneakers. When an impact force is applied to a shoe equipped with an air tube, the hollow portion of the air tube is sealed with air filled, so that the compressed air flows into a non-compressed area where the top plate is not pressed. The upper and lower plates of the unpressed area are inflated in the up and down direction, and a temporary bulging phenomenon occurs in the unpressed area, so that the sneakers have a shock-lowering function and a bad fit.

Korean Utility Model Registration No. 20-0176002 relates to a shock absorbing shoe that absorbs shock by mounting a spring on the midsole portion of the shoe. Utility Model Registration No. 20-0176002 developed an air tube sneaker equipped with a shock absorbing spring to improve the problem of the sneaker equipped with an air tube. Utility Model Registration No. 20-0176002 is equipped with a shock absorbing cushion unit in which a spring is installed parallel to the midsole of the shoe sole. However, Utility Model Registration No. 20-0176002 forms a locking jaw at the outer circumferential portions of the plurality of through holes formed in the upper pad and the lower pad, and the spring is mounted so that the upper and lower ends of the spring are hooked up and held by the locking jaw, respectively. will be. As a utility model registration No. 20-0176002, a shoe with a spring does not have a protective device to fix the spring when the spring is compressed. Therefore, when the spring is compressed by the external impact force, the spring itself is rubbed. There is a problem that can not be used as a shock-absorbing shoes because the problem occurs that the spring breaks or breaks and the spring is separated from the locking jaw and further springs go through the bottom of the shoe. Utility Model Registration No. 20-0176002 is a method of injecting the upper pad, the lower pad, and the spring through the injection mold using a separate mold, and then bonding the upper pad, the lower pad, and the spring storage through-hole to high frequency or bond. Since it must be manufactured, there was a problem that can not be used as a shock-absorbing shoe.

In addition, Korean Patent Application No. 2003-53584 relates to a shock-absorbing shock absorber for relieving shock by mounting a coil spring on the midsole of the shoe. Korean Patent Application No. 2003-53584 has a plurality of annular flanges formed on an upper pad and a lower pad, and a spring is fitted by forcibly fitting a coil spring to the flange. However, Korean Patent Application No. 2003-53584 has a problem in that the coil spring is pulled out of the flange or the spring itself is broken when the coil spring mounted on the shock absorber is compressed or inflated by applying an impact force to the shoe. In Korean Patent Application No. 2003-53584, an annular flange fitted with a coil spring when the coil spring mounted on the shock absorber by applying a shock force to the shoe is compressed, does not function as a protective rod to support and protect the spring and is annular by a strong force. There was a problem that the flange itself is broken or broken.

In addition, in Korean Patent Application No. 2003-53584, the sum of the height (h ₁ ) of the flange formed on the upper pad and the height (h ₂ ) of the flange formed on the lower pad is smaller than the height (x) of the spring at the maximum compression of the coil spring. If formed, the upper and lower flanges do not act as a protective rod to secure the spring fixed, so that a strong impact is applied to the bottom of the shoe has a problem that the spring is separated or broken. When the sum of the height (h ₁ ) of the flange formed on the upper pad and the height (h ₂ ) of the flange formed on the lower pad is smaller than the height (x) of the spring at the maximum compression of the coil spring, the spring itself is rubbed when the spring is compressed. When the spring itself acts as a fixed rod in the shock absorber, the strong impact applied to the bottom of the shoe is transmitted to the compressed spring itself, which acts as a fixed rod, causing the spring to break away or to be broken. There was a problem that the state itself goes through the outsole of the shoe.

In addition, in Korean Patent Application No. 2003-53584, when the spring itself serves as a fixed rod, the upper and lower pads are torn or broken by a strong impact applied to the bottom of the shoe as the shoes are used, and the spring sweats when the pads are broken. However, the moisture is soaked in the spring is rusted and the spring was rusted, if you continue to use the shoes there was a problem that the spring is broken.

In addition, in Korean patent application No. 2003-53584, when manufacturing a shoe equipped with a shock absorber, a separate storage compartment for attaching the shock absorber to the midsole should be configured, and the midsole having a separate storage compartment is separately cushioned after the midsole is manufactured. Since the device should be mounted, it should be manufactured by high frequency bonding method or bond bonding method, and injection pylon (PHYLON: foamable ethylene vinyl acetate) had a problem that cannot be manufactured by the manufacturing method of midsole. In addition, in Korean Patent Application No. 2003-53584, in the case of manufacturing a shoe equipped with a shock absorber, when the outer air cover is not wrapped in the shock absorbing shoe shock absorber, injection pylon (PHYLON: foamable ethylene vinyl acetate) There was a problem in that it is not possible to manufacture the midsole in the manner and to manufacture shoes by the adhesive bond method. When the outer air cover is not packed in the shock absorber cushioning device, the shock-absorbing functional well-being shoe cushioning device of the present invention is inserted into the upper and lower injection molds, and the pylon foaming enters between the shock absorber and the spring. There was a problem that can not produce shoes by the pylon foam method.

The sneaker of the shock-absorbing functional well-being shoes of the present invention surrounds the outsole 101 forming the bottom of the shoe, the midsole 103 attached to the top of the outsole, and the upper area attached to the top of the midsole to accommodate the user's foot. It consists of an upper sole 105 and a shock absorbing member 110 which is installed equilibrium in the midsole portion to form a space. On the upper surface of the midsole 103 inside the sneaker is attached to the insole 107 is in contact with the sole of the person exercising.

One or more shock absorbing members are mounted on the midsole portion of the rear axle of the sneaker. In addition, one or two shock absorbing members are mounted on the midsole portion of the sneaker sole as well as on the midsole portion of the heel of the sneaker. The shock absorbing member includes an upper pad 112; A lower pad 114 which is disposed in the upper and lower sides of the upper pad in parallel with the upper pad while maintaining a constant distance therebetween; A plurality of spring fixing protrusions 116 for fixing the coil springs to the inner surfaces of the pads, the upper part and the lower part of which correspond to each other; It is composed of a plurality of coil springs 118 interposed between the upper pad and the lower pad in the state fixed to the spring fixing protrusion to mitigate the impact so that the shock transmitted from the bottom of the shoe to the user's foot can be alleviated by the coil spring. Can be.

In the shock-absorbing functional well-being shoe buffer of the present invention, a plurality of fixing protrusions are formed on the inner surface of the upper pad and the inner surface of the lower pad. Shoes with regular springs can cause the spring to twist itself or generate noise from the spring when it gives a strong impact to the shoe. By the way, the present invention has a locking jaw is formed in the lower portion of the fixing projection, the lower end of the spring is caught on the locking jaw prevents the spring from being broken or twisted when it is contracted or expanded and prevents noise that may occur in the spring itself. . In addition, in the present invention, the fixing protrusion has a tapered angle 116-2 from the upper end of the locking jaw to the upper end of the protrusion to form a tapered angle 116-2 to prevent the spring from being twisted or broken by an external force and is generated from the spring itself. Prevent noise In the present invention, it is preferable that the spring fixing protrusion has a tapered angle 116-2 from 30 to 85 degrees from the bottom to the top of the protrusion. When the tapered angle 116-2 of the fixing protrusion is formed at 85 ° or more, the taper is not formed on the protrusion, and the spring mounted on the shoe collides to generate noise or noise from the spring itself. If the tapered angle 116-2 of the fixing protrusion is formed to be 30 ° or less, it cannot form a locking jaw in the fixing protrusion, and when the spring is not fixed to the locking jaw, the spring mounted on the shoe hits the noise or the spring itself Noise is generated from the

In addition, in the shock-absorbing functional well-being shoes shock absorber of the present invention, the spring fixing protrusion has the same height (h ₁ ) of the upper fixing protrusion and the height (h ₂ ) of the lower fixing protrusion, as well as the height of the upper fixing protrusion (h). ₁ ) and the height (h ₂ ) of the lower fixing projections is formed to be different. In addition, in the shock-absorbing functional well-being shoes shock absorber of the present invention, the spring fixing protrusion is the sum of the height h ₁ of the fixing protrusion formed on the upper pad and the height h ₂ of the fixing protrusion formed on the lower pad. It is larger than the height (x) of the sea spring. If the height of the spring (x) is 8mm at the maximum compression of the coil spring, the sum of the height (h ₁ ) of the fixing protrusions formed on the upper pad and the height (h ₂ ) of the fixing protrusions formed on the lower pad should be at least 8 mm in size. May act as a fixing rod to protect the spring. In the shock-absorbing functional well-being shoes shock absorber of the present invention, the sum of the height h ₁ of the fixing protrusion formed on the upper pad and the height h ₂ of the fixing protrusion formed on the lower pad is the height of the spring at the maximum compression of the coil spring ( When formed larger than x), the upper and lower fixing projections act as a protective rod to fix the spring so that the spring does not break or break even if a strong impact is applied to the sole of the shoe. The height of the fixing protrusion when the height of the spring (x) is 8mm and the sum of the height (h ₁ ) of the fixing protrusion formed on the upper pad and the height (h ₂ ) of the fixing protrusion formed on the lower pad is 8mm when the coil spring is compressed at maximum. It is preferable to use a pad whose (h ₁ , h ₂ ) is 4 mm.

However, when the sum of the height h ₁ of the fixing protrusions formed on the upper pad and the height h ₂ of the fixing protrusions formed on the lower pad is smaller than the height x of the spring at the maximum compression of the coil spring, the spring is compressed. The friction itself causes the spring itself to act as a stationary rod. In the shock-absorbing functional well-being shoe buffer of the present invention, when the spring itself serves as a fixed rod, a strong impact applied to the bottom of the shoe is transmitted to the compressed spring itself serving as a fixed rod, and thus the spring is separated or broken and further compressed. The spring itself will break through the sole of the shoe. In addition, when the spring itself acts as a fixed rod in the shock absorber functional well-being shoe shock absorber of the present invention, the upper pad and the lower pad are torn or broken by a strong impact applied to the bottom of the shoe as the shoe is used, and the pad is broken. If the spring is wicked with sweat or moisture, the spring will be rusted. If you continue to use the shoes with the spring rusted, the spring will be broken.

In addition, the shock-absorbing functional well-being shoe shock absorber of the present invention is formed in a pair of two to four pairs of spring fixing protrusions on the inner surface of the upper and lower pads in order to prevent noise that may occur in the space during the contraction and expansion of the spring. It is preferable to form 3 pairs in a line, and it is most preferable. Shock-absorbing functional well-being shoes shock absorber of the present invention has a spring displacement (y) of 16mm at the time of relaxation to prevent temporary bulging due to the depressed area when applying a force to the upper pad and the displacement of the spring at the maximum compression (x) It is preferable to arrange three pairs of coil springs which are 8 mm in a row.

In addition, in the shock absorbing functional well-being shoes shock absorber of the present invention, the coil spring is preferably formed in a square cross-sectional shape to prevent the breakage of the spring itself, the maximum compression so that the spring itself can perform the shock-releasing functional well-being action to the maximum. Preferably, the displacement x of the sea spring is 50% of the spring displacement y upon relaxation. In the shock-absorbing functional well-being shoe shock absorber of the present invention, the coil spring has a spring displacement (y) of 16 mm at relaxation and a spring displacement (x) of 8 mm at maximum compression.

In addition, in the shock-absorbing functional well-being shoes shock absorber of the present invention, the coil spring is preferably plated with a dark color to support a strong impact force, and prevents the spring from expanding or stretching even when a strong impact force is applied to the spring, and the upper pad by expansion of the spring. Alternatively, it is preferable to use a strong coil spring plated with dark to prevent the bottom pad from swelling. The coil spring is preferably coated with luminous or fluorescent material to prevent rust and to see the shock absorber mounted on the shoe from the outside. In addition, the upper and lower pads in the shock-absorbing functional well-being shoe buffer of the present invention is generally made of a polymer resin. However, the present invention prevents the spring itself from twisting or crushing to one side by the strong impact applied to the bottom of the shoe, and the upper and lower pads are injected into the polyurethane polymer or the polyurethane elastomer to prevent the shoe from being torn or broken. It is preferable to produce. In addition, when the spring is mounted on the shoe, the upper pad and the lower pad are made of hardness (Shore A) to prevent noise generated by the spring itself and to prevent the spring itself from twisting or crushing to one side due to the strong impact on the bottom of the shoe. After 24 hours) injection molding with a 75 to 90 polyurethane polymer is preferred. When injection molding the upper pad 112 and the lower pad 114 using polyurethane having a hardness of 90 or more (after Shore A / 24 hours), the spring mounted on the shoe collides to generate noise, and the spring itself generates noise. It can have a strong feeling of rejection for the person who wears the shoes and affect the noise. When injection molding the upper and lower pads using polyurethane (less than Shore A / 24 hours) of 75 or less, the hardness of the pad itself is weak and the spring mounted on the shoe hits the noise, or the spring itself generates noise. .

In addition, the shock-absorbing functional well-being shoe shock absorber of the present invention further includes an outer air cover 120 that surrounds the outside of the upper pad and the lower pad to form an air chamber filled with air therein. When the outer air cover 120 is packed in the shock-absorbing functional well-being shoe buffer device 110 of the present invention, an air chamber in which air is filled is formed, and an air chamber in which the outer air cover is formed is filled with shoes. Even if an impact is applied to the upper pad or the lower pad, the shock applied to the primary pad can be primarily mitigated, and at the same time, the external shock is mitigated by the elastic force of the spring.

If the shock absorber is not packed with an outer air cover in the shock absorber, the midsole cannot be manufactured by injection pylon (foamable ethylene vinyl acetate) in the production of the midsole. When manufacturing shock-mounted shoes, if the outer air cover is not wrapped in the shock absorber, the shoes should be manufactured by high frequency bonding or bond bonding. If the shock absorber is not packaged with an outer air cover, if the shock absorber is placed inside the upper and lower injection molds and the foam is produced, the foam can not be made into the shock absorber.

However, when the outer air cover is packaged in the shock absorber, the midsole can be manufactured by injection pylon (foamable ethylene vinyl acetate) without producing the midsole by high frequency bonding or bond bonding. In addition, when the outer air cover is packaged in the shock absorber, the cushioning device is inserted into the upper and lower injection molds without making the shoes by the high frequency bonding method or the bond bonding method, and the shoes are injected by the injection pylon (PHYLON: foamable ethylene vinyl acetate) method. I can make it.

The outer air cover is preferably made of a polyvinyl chloride resin, polyvinyl acetate resin, polystyrene resin, ABS resin, acrylic resin, polyethylene resin, polypropylene resin and a thermoplastic resin including polyethylene vinyl acetate, stretchable polyvinyl resin Most preferred.
