Definitions

  • the present invention relates to a shoe sole having an upwardly sloped front side and an upwardly rear side so that it has a substantially arch-shaped bottom surface, in which a middle sole made of a rigid material is embedded in an outsole. More particularly, the present invention relates a shoe sole capable of allowing a user to walk in such a manner that the total portions of the foot can contact the ground in sequence with absorbing a shock given by a weight of the user while walking, by attaching an elliptical stamping cushion made of a material that is a softer than the outsole in an arch-shaped groove formed at a rear lower portion of the outsole, and which is capable of allowing the stamping cushion to be rapidly compressed and to rapidly expand so as to alleviate the shock by embedding a plate spring having a circular shape in a main body of the stamping cushion, and which is capable of preventing water from penetrating into the main body of the stamping cushion by installing a waterproof cover on an outer surface of the stamping cushion.
  • a prior art shoe sole structure is shown in Korean Utility Model Registration No. 226048.
  • This shoe sole structure includes a resilient material, which has a U-shape and is embedded in a heel portion of an outsole usually made of polyurethane. If a user putts on a shoe having the shoe sole, the weight of the user tends to concentrate in the heel portion while wearing the shoe. Then, the U-shaped resilient material becomes slightly constricted and it has a function of supporting the weight of the user, thereby absorbing and alleviating a shock given to the sole of the foot to a minimum.
  • the resilient material comprises a U-shaped steel plate having a smooth surface.
  • the outsole is usually made of polyurethane and the resilient material is made of the steel plate, so that they cannot firmly combine with each other.
  • the U-shaped resilient material becomes constricted and restored repeatedly, thereby absorbing and alleviating a shock given to the sole of the foot. Since the outsole and the resilient material are not firmly combined with each other, a nerve-racking noise may be generated there between at the time of contacting the ground. In addition, the outsole usually made of polyurethane tears easily because of the contact with the U-shaped resilient material made of steel plate.
  • FIG. 575875 Another prior art shoe sole structure is shown in Korean Patent Registration No. 575875.
  • This shoe sole structure includes an outsole having a rear side slanted upwards.

  • FIG. 6 shows a plate spring 22 a according to the second preferred embodiment of the present invention.
  • the plate springs 22 a are made of an elastic metal plate.
  • the plate spring 22 a has circular-shaped tension portions 23 and rounded resilient portions 25 , which are integrally formed with each other. Both ends of the resilient portion 25 are integrally connected with one side of the circular-shaped tension portion 23 , respectively.
  • the resilient portion 25 extends between the circular-shaped tensions portions 23 .
  • the resilient portion 25 is radially outwardly rounded between the circular-shaped tension portions 23 . This structure widens the space between two resilient portions 25 .
  • a reinforcing portion 26 is added to an outer surface of the resilient portion 25 in a cylindrical embossing pattern thereon, respectively, thereby forming an X-shaped pattern. At positions adjacent to the reinforcing port ion 26 , a plurality of through holes 27 are formed through the resilient portion 25 .
  • FIGS. 1 to 6 the operational relationship of the shoe sole can be understood as follows with reference to accompanying drawings FIGS. 1 to 6 .
  • the shoe sole according to the present invention may be attached to a bottom surface of a shoe sheath. If a user walks on a street while wearing the shoe having this shoe structure, the heel is the first portion of the foot to contact the ground. That is, if the user walks on a street to Masai's manner of walking, the heel portion of the foot contacts the ground earliest of all.
  • a front side and a rear side of the bottom surface of the outsole 10 of which the middle sole 20 is attached to the upper surface of the outsole 10 are sloped upwardly, thereby forming a substantially arch shape of the shoe.
  • the heel is the first portion of the foot to contact the ground. As the step continues and the remainder of the foot contacts the ground, the weight of the body is carried forward along the outer circumferential side of the foot. If the heel leaves the ground, the weight of the body shifts back towards the medial side of the foot. Continuously, if the medial side leaves the ground, the weight of the body shifts back towards the toe, especially a great toe of the foot.
  • the elliptical stamping cushion 20 is installed in the arch-shaped groove 11 formed at a rear lower portion of the outsole 10 , which is corresponding to the hill portion contacting the ground at first. Since the stamping cushion 20 is made of a material that is a softer than the outsole 10 and a pair of plate springs 22 is embedded in the main body 20 a of the stamping cushion 20 , the stamping cushion 20 can primarily absorb the shock given by a weight of the user while walking.
  • the plate springs 22 embedded in the stamping cushion 20 is also compressed, thereby absorbing the shock given by a weight of the user while walking.
  • the plate springs 22 restores its original state due to the elastic force thereof and the stamping cushion 20 restores its original oval shape.
  • the stamping cushion 20 contacts the wet ground and then it is compressed while walking, water can flow into the main body 20 a of the stamping cushion 20 , which is made of a material belonging to the sponge system. Because of the waterproof cover 21 is attached to an outer surface of the stamping cushion 20 or is wound around or applied onto the total outer surface of the main body 20 a of the stamping cushion 20 , it is possible to prevent water from flowing into the stamping cushion 20 while it being compressed.
  • the main body 20 a of the stamping cushion 20 If water flows into the main body 20 a of the stamping cushion 20 , the main body 20 a made of a material belonging to the sponge system hydrolyzes and thereby it is apt to corrode. Since the waterproof cover 21 for preventing water from penetrating into the main body 20 a of the stamping cushion 20 is attached to the total outer surface of the stamping cushion 20 , it is possible to prevent water from flowing into the main body 20 a of the stamping cushion 20 while it being compressed. Accordingly, there is nothing to worry about the corrosion of the main body 20 a of the stamping cushion 20 .
  • the main body 20 a of the stamping cushion 20 is made of a material belonging to the sponge system and a pair of plate springs 22 embedded in the main body 20 a of the stamping cushion 20 is made of the steel plate. That is, since the main body 20 a is usually made of polyurethane and the plate springs 22 are made of the steel plate, they cannot firmly combine with each other.
  • the reinforcing portion 26 is added to the outer surface of the resilient portion 25 in a cylindrical embossing pattern thereon, respectively, thereby forming an X-shaped pattern.
  • a plurality of through holes 27 are formed through the resilient portion 25 .
  • a rounded portion 28 is formed at a free end of the resilient portion 25 , respectively. Due to this structure, the plate springs 22 are firmly combined with the main body 20 a . Since the outwardly projected portions, the recessed portions and the through holes 27 in the reinforcing portion 26 are filled with the materials of the main body 20 a , the materials of the main body 20 a are integrally formed together.
  • the rounded portion 28 is combined with the materials of the main body 20 a in such a manner that it is driven into the materials of the main body 20 a . Consequently, the plate springs 22 are firmly combined with the materials of the main body 20 a.
  • the support pin 24 is inserted into the opening of the circular-shaped tension portion 23 of the plate spring 22 . If the plate spring 22 is continuously compressed and restores its initial state, the circular-shaped tension portion 23 is apt to cause breakage owing to the fatigue accumulated thereon. At this time, the support pin 24 inserted into the opening of the circular-shaped tension portion 23 prevents the circular-shaped tension portion 23 from being compressed and restoring its initial state, thereby minimizing the breakage of the circular-shaped tension portion 23 .
  • the main body 20 a made of soft materials belonging to the sponge system is apt to cause breakage by means of the distal end of the resilient portion 25 made of steel plate.
  • the rounded portion 28 is provided at the distal end of the resilient portion 25 so that it is possible to minimize the breakage of the main body 20 a of the plate spring 22 .
  • the plate spring 22 has a relatively wide width of 40 mm or so. If a user walks on a street while wearing the shoe, the plate spring 22 is not always equally stepped on by means of the heel. Since different persons have different manners of walking and the road is not always smooth, the plate spring 22 is unevenly inwardly or outwardly stepped on by means of the heel.
  • the reinforcing portion 26 is added to the outer surface of the resilient portion 25 in a cylindrical embossing pattern thereon, respectively, thereby forming an X-shaped pattern. Due to this structure, if the plate spring 22 is continuously stepped on to one side by means of the heel, the reinforcing portion 26 supports the plate spring 22 so as to prevent the plate spring 22 from being transformed. As a result, the stamping cushion 20 can be equally stepped on and restore its initial state while walking.
  • the middle sole 30 made of a rigid material is embedded in the outsole 10 .
  • This middle sole 30 has an arch shape that is substantially the same as the shape of the outsole 10 so as to continuously maintain the arch shape of the outsole 10 .
  • the rib-shaped reinforcing portion 33 is provided at a middle portion of the middle sole 30 . This rib-shaped reinforcing portion 33 has a function of preventing the middle portion of the middle sole 30 from unfolding so that the middle portion 30 is not transformed.
  • the middle sole 30 of the walking shoe according to the present invention is made of soft foam polyurethane and is embedded in the outsole 10 , it is possible to attenuate the oppressive feeling and to alleviate the pain applied to the sole of the foot.
  • the shoe sole of the present invention has significant advantages over previously known shoe sole.
  • the uneven surface 31 is provided on an upper surface and a lower surface of the middle sole 30 , respectively.
  • a plurality of through holes 32 are formed through the middle sole 30 and a plurality of cut-away portions 34 are formed at positions of the front side of the middle sole 30 . Due to this structure, the middle sole 30 is firmly combined with the outsole 10 so that it is possible to prevent the middle sole 30 from being released from the outsole 10 .
  • the pluralities of cut-away portions 34 are formed at positions of the front side of the middle sole 30 , which are corresponding to the toe, thereby forming resilient supporting portions 35 .
  • the toe is corresponding to the resilient supporting portions 35 .
  • the user feels at ease due to operation of the resilient supporting portions 35 .
  • this front portion of the middle sole 30 can be easily bent so that the user can move the toe with easy.
  • the plate spring 22 a according to the second embodiment of the present invention operates in the same manner as the plate spring 22 according to the first embodiment of the present invention, except for partial operation.
  • the rounded resilient portions 25 are integrally formed with the circular-shaped tension portions 23 and extend between the circular-shaped tensions portions 23 . Between the circular-shaped tensions portions 23 , the resilient portions 25 are radially outwardly rounded and they exhibit an elastic force. Accordingly, the plate spring 22 a is formed as a substantially oval shape. Due to this structure, when the plate spring 22 a is continuously compressed and restores its initial state, it is possible to prevent the plate spring 22 a from being damaged.
  • the reinforcing portion 26 is added to an outer surface of the resilient portion 25 in a cylindrical embossing pattern thereon, respectively, thereby forming an X-shaped pattern. Accordingly, the degree of strength of the resilient portion 25 is enhanced due to operation of the reinforcing portion 26 . If the resilient portion 25 is pressed down at its outer side or inner side, it is possible to minimize the excessive compression of the resilient portion 25 due to operation of the reinforcing portion 26 . As a result, it is possible to prevent the user from getting sprained due to operation of the reinforcing portion 26 .
