Definitions

  • the present invention relates to a shoe sole, and more particularly to a shoe sole, wherein an angle of a portion corresponding to toes is regularly maintained at any time for attaining the correct walking mechanism of the sole of the foot.
  • the sole of a person may be partitioned into a toe part, an arch part and a heel part from the front side.
  • the general walking mechanism of the sole of the foot will be explained as follows.
  • the heel of the right foot for example contacts the ground first, and almost at the same time, the arch part becomes in contact with the ground.
  • the left foot is moved to the front side.
  • the heel part and arch part of the right foot are upward separated from the ground.
  • the toe part is thoroughly attached onto the ground.
  • the toe part pushes the ground to move one's body forward.
  • the heel part is moved upward, so that an angle formed by the toe part and heel part greatly differs from that of normal times.
  • Such a walking mechanism is repeatedly executed by alternating the right foot and left foot.
  • the above-described walking mechanism cannot be appropriately maintained when using a conventional shoe sole.
  • the foregoing walking mechanism cannot be performed. That is, the conventional shoe sole is flat to be detrimental to performing the above-stated normal walking mechanism. Therefore, when the shoe provided with the conventional shoe sole is worn, the gait becomes abnormal to negatively walk with a measure step.
  • the angle of the portion corresponding to the toe part of the shoe sole has a specific value, but the shape thereof is easily deformed during wearing the same to have no effect. Moreover, in order to make the angle of the portion corresponding to the toe part have the specific value, the shoe sole should be thick to involve a problem of significantly consume the materials.
  • the present invention is developed to solve the aboveenumerated conventional problems. Accordingly, it is an object of the present invention to provide a shoe sole for allowing the foot to perform the normal walking mechanism by maintaining the angle of the front end of the shoe sole corresponding to the toe part by a constantly regular angle.
  • a shoe sole formed by joining a middle sole and a bottom sole to provide a regular inclination angle upon a front end corresponding to a toe part includes an elastic plate embedded into the internal front end of the bottom sole for allowing the front end of the bottom sole to maintain an inclination angle within a range of 5° to 20°.
  • FIGS. 1 to 3 One embodiment of the present invention is illustrated in FIGS. 1 to 3.
  • the shoe sole 10 herein illustrated is formed by a bottom sole 20 and a middle sole 30.
  • Bottom sole 20 forms the lower portion of shoe sole 10, which becomes in contact with the ground.
  • Bottom sole 20 has the front end upwardly-slanted by as many as a regular angle ⁇ .
  • regular angle ⁇ has a value within a range of 50 to 20°, and most preferably, 13.7°.
  • 13.7° is the upwardly-slanted angle of the toe in view of the normal sole of one's foot.
  • Bottom sole 20 is embedded with an elastic plate 25 for maintaining the angle of the front end of bottom sole 20 with the above value.
  • Elastic plate 25 also has the front end which is upwardly-slanted by as many as 5° to 20° with respect to the rear end thereof.
  • elastic plate 25 may be formed of a plastic resin only. At this time, the hardness thereof is to be larger than that of the bottom sole while the elasticity is provided. Otherwise, the plastic resin is mixed with any one of a material selected from the group consisting of metal particles, glass fiber particles, carbon fiber particles and glass carbon fiber particles.
  • the elastic plate can be formed by mixing 90% of plastic resin with 10% of metal particles; 80% of plastic resin with 20% of glass fiber particles; 75% of plastic resin with 25% of carbon fiber particles; or 80% of plastic resin with 20% of glass fiber particles.
  • the mixing is performed in the ratio of 6:4.
  • the reason of mixing the variety of materials in the variety of ratios is for using a suitable one in accordance with the kind of a shoe 40.
  • Such elastic plate 25 has a characteristic of considerably great elasticity in considering the property of the substance utilized. Consequently, the shape of the bottom sole is not deformed regardless of wearing shoe 40 for a long time period.
  • Middle sole 30 is placed onto the upper plane of bottom sole 20, of which front end is upwardly-slanted, too.
  • FIG. 3 illustrates another embodiment of the present invention, in which an elastic plate 35 is embedded into a middle sole 30. That is, elastic plate 35 is embedded into middle sole 30 to maintain the angle of the front end of middle sole 30 within the range of 5° to 20°.
  • the front end of bottom sole 20 is upwardly-slanted by as many as 5° to 20°.
  • FIG. 4 illustrates still another embodiment of the present invention.
  • shoe sole 10 is formed by only bottom sole 20, of which front end is upwardly-slanted by as many as 5° to 20°.
  • elastic plate 25 is embedded into the front end for maintaining the slope of the front end of bottom sole 20. Since the substance, shape and the like of elastic plate 25 are the same as those of foregoing embodiments, further description will not be presented.
  • shoe sole 10 has the front end upwardly-slanted by approximately 13.7° to consistently distribute one's body weight throughout the arch part and heel part of the sole of one's foot, thereby lowering the fatigue of the leg muscle.
  • the aforementioned walking mechanism can be correctly executed. That is, when the person walks around in one's bare feet, the heel part of the sole of one's foot contacts the ground first, and the arch part is then in contact with the ground. Lastly, while the toe part of the foot touches the ground, the heel part is detached from the ground. The toe part is further closely attached to the ground at the moment the heel part is detached from the ground, and the toe part is separated from the ground while the toe part pushes the ground. In this walking mechanism, a contact point between the sole of the foot and ground is continuously moved from the heel part to the toe part.
  • the above-stated walking mechanism can be correctly performed when wearing shoe 40 provided with shoe sole 10 according to the present invention. More specifically, the front end of shoe sole 10 is formed to have the angle identical to the upwardly-slanted angle of the toe part, so that the normal walking mechanism is performed even when walking in one's shoes. That is, since the front end of shoe sole 10 is formed to be upwardly slanted, the contact point of shoe sole 10 with the ground is moved from the rear end to the front end while the front end of shoe sole 10 is naturally in contact with the ground. Thus, the normal walking is performed as a tire rolls over and over.
  • the toe part never fails to press the ground just before the foot is separated from the ground.
  • the arch part of the sole of the foot is continuously stimulated to excite the spots on the body suitable for acupuncture, thereby being good for health.
  • the shoe sole according to the present invention is applied to mountain-climbing boots, the forward sliding of the foot within the mountain-climbing boot is prevented to make it possible to protect the toes when descending the mountain. Furthermore, it is effective when those who wear the shoes for a long time like soldiers or medical staffs employ the shoe sole according to the present invention.
  • the elastic plate is inserted into the bottom sole or inner sole to lead the front end to upwardly slant, thereby realizing the correct walking mechanism. Therefore, the shoe sole is advantageous of having favorable sense when being worn, inhibiting the fatigue upon the leg muscle when being walked for a long time period, and stimulating the spots of the body suitable for acupuncture distributed throughout the sole of the foot to be good for health.
