Definitions

  • the present invention relates to a multi-layered shock- absorbing structure for a shoe sole and, more particularly, to a multi-layered shock-absorbing structure for a shoe sole, in which shocks transmitted to a human body when the shoe sole contacts the ground are distributed and relieved step by step through a multi-layered structure, thereby increasing shock absorption to effectively prevent worsening of wearing sensation and injuries caused by the shocks, and increasing durability to correctly perform its original function over a long period.
  • a shoe sole is a constituent of a shoe, and absorbs shocks transmitted to a human body due to the weight thereof when the shoe contacts the ground, and simultaneously prevents the shoe from sliding on the ground.
  • the shoe sole can improve the wearing sensation of the shoe, and can promote stable walking.
  • the shoe sole must simultaneously exhibit good shock absorption and ground contact force.
  • shock-absorbing means are embedded in front and rear parts or a rear part of the shoe sole so as to exhibit good shock absorption.
  • This shock- absorbing means has various structures, which will be described below.
  • the most common structure is an airbag type in which air is airtightly injected in the shoe sole, so as to absorb shocks using the pressure of air.
  • a typical structure is an erect spring type in which a plurality of springs stands erect in the shoe sole so as to absorb shocks using the elasticity of the springs.
  • a shock-absorbing space is defined between a midsole and an outsole so as to absorb shocks using a leaf spring function based on the space.
  • shock-absorbing means have a single structure that absorbs shocks all at once.
  • the shock-absorbing means fails to perform its original function, and serves merely to double the weight of the shoe sole.
  • the weight of the shock-absorbing means increases the fatigue of a foot, far from conducting the shock-absorbing function.
  • the present invention has been made in an effort to solve the problems occurring in the related art, and an object of the present invention is to provide a multi- layered shock-absorbing structure for a shoe sole, which absorbs shocks using a multi- layered structure rather than a single layered structure, thereby correctly performing its original function even after long-term wearing, to thus relieve the fatigue of a foot and effectively prevent injuries caused by the shocks.
  • a multi- layered shock-absorbing structure of a shoe sole absorbs shocks transmitted from the ground to the heel of the shoe sole due to a load
  • the midsole of the heel constituting the shoe sole, is divided into an upper midsole and a lower midsole having a leaf spring shape by an arcuate shock-absorbing space
  • a shock-absorbing ball case in which a hemispherical shock-absorbing ball is held, protrudes downward from the middle of the upper midsole so as not to contact the lower midsole
  • a disc-shaped shock-absorbing plate having at least one air vent hole is installed in a shock-absorbing plate fitting hole formed in the middle of an outsole.
  • the shock-absorbing case may include protrusions at regular intervals on the inner surface thereof, and shock- absorbing slots defined by the protrusions.
  • the multi-layered shock- absorbing structure for a shoe sole distributes and relieves shocks transmitted to a human body when the shoe sole contacts the ground step by step through a multi- layered structure, so that it can increase shock absorption to effectively prevent the worsening of the wearing sensation and injuries caused by the shock, and improve durability so as to correctly perform its original function over a long period.

  • the multi-layered shock-absorbing structure 100 of a shoe sole of the present invention is designed so that the part absorbing the shocks has a multilayered structure, and thus it can maximize the function of absorbing the shocks of the shoe sole, and increase the duration of the shock-absorbing function. Thereby, even if the shoe is worn for a long time, the multi-layered shock-absorbing structure 100 can correctly perform its original function.
  • the multi-layered shock-absorbing structure 100 is designed so that the midsole 1 of the shoe sole, constituting the shoe heel, is divided into the upper midsole 3 and the lower midsole 4 having the shape of a leaf spring by the arcuate shock-absorbing space 2, and the shock-absorbing ball case 7, in which the hemispherical shock-absorbing ball 6 is held, protrudes downwardly from the middle of the upper midsole 3 so as not to contact the lower midsole 4, and the disc-shaped shock-absorbing plate 10 having at least one air vent hole 9 is installed in the shock- absorbing plate fitting hole 8 formed in the middle of the outsole 5.
  • the operation of the multi-layered shock- absorbing structure 100 will be described below in detail.
  • shock relieved by the shock- absorbing ball 6 is again relieved by the elasticity of the shock-absorbing ball case 7 supporting the shock-absorbing ball 6 while being absorbed until the shock-absorbing ball case 7 contacts the lower midsole 4.
  • shock-absorbing slots 12 are defined in the inner surface of the shock- absorbing ball case 7 by the protrusions 11, the shock-absorbing slots 12 function as airbags to absorb the shock to some extent.
  • shock relieved by the shock-absorbing space 2 and the lower midsole 4 is again relieved by an air resistance structure and a leaf spring structure, which are provided by the shock-absorbing plate fitting hole 8 of the outsole 5 and the shock- absorbing plate 10 while being absorbed until the shock- absorbing plate 10 contacts the ground.
  • shock transmitted from the ground due to the load when the shoe sole contacts the ground is sequentially distributed and thus completely relieved by the multi-layered structure provided by the shock- absorbing ball case 7, the shock- absorbing ball 6, the shock-absorbing slots 12, the shock-absorbing space 2, the lower midsole 4, the shock-absorbing plate fitting hole 8, and the shock-absorbing plate 10.
  • the multi-layered shock-absorbing structure can maximize shock absorption to further improve the wearing sensation of the shoe, and can effectively prevent injuries to a human body due to the shocks.
  • the multi-layered shock-absorbing structure absorbs the shock step by step to increase the durability of the shoe, so that it can solve the problem of a conventional multi-layered shock-absorbing structure, which relieves the shock in a single step to reduce durability and fails to correctly exhibit the shock absorption over a long period.
  • the multi-layered shock-absorbing structure 100 of a shoe sole of the present invention increases the durability along with the shock absorption, so that it can effectively prevent injuries caused by the shock and improve the wearing sensation of the shoe even after it has been worn for a long time.
