Abstract

A shoe sole includes: a sole unit defining at least one recess; at least one elastic body received in the recess and having a cellular structure that defines at least two levels of cells, the two levels of the cells being disposed one above the other, each of the cells defining a cell space therein; and a filler material that fills the cell space of each of the cells.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates to a shoe sole, more particularly to a shoe sole including an elastic body having a cellular structure that defines a plurality of horizontally extending cells.

  • FIG. 1 illustrates a conventional shoe sole 1 attached to an upper of a footwear article. The shoe sole 1 includes an outsole 10 formed with a recess 11, and an elastic body 12 received in the recess 11. The elastic body 12 is formed with a plurality of vertically extending through-holes 13, each of which is filled with a filler 14 so as to provide a shock absorbing effect. However, since the structure thus formed for the elastic body 12 has a relatively poor compressibility in a compression direction (Y) toward the ground, the shock absorbing effect provided by the conventional shoe sole 1 is relatively poor when a downward force (F) is applied to the shoe sole 1.

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • FIGS. 2 to 4 illustrate the first preferred embodiment of a shoe sole of a footwear article according to this invention.
  • The shoe sole includes: a sole unit 2 defining at least one recess 20; at least one elastic body 3 received in the recess 20 and having a cellular structure that defines at least two levels of cells 30, the two levels of the cells 30 being disposed one above the other, each of the cells 30 defining a cell space therein; and a filler material 34 that fills the cell space of each of the cells 30.
  • In this embodiment, the sole unit 2 includes an outsole 21 that defines the recess 20 disposed at a heel portion of the shoe sole, and a tread member 22 attached to the outsole 21 and covering a bottom side of the recess 20. The cellular structure of the elastic body 3 has a surrounding wall 31 that defines an inner space 310 and that is disposed between and that is attached to the outsole 21 and the tread member 22, and a plurality of interconnected webs 32 that are disposed in the inner space 310 and that are connected to the surrounding wall 31 so as to define the cells 30. Note that the webs 32 and the surrounding wall 31 are formed integrally into one single piece in this embodiment.
  • Preferably, the filler material 34 is selected from the group consisting of gel, silicone, polyurethane resin, and soft rubber.
  • The surrounding wall 31 has two open ends 35 that are opposite to each other in a horizontal direction (Z). Each of the open ends 35 of the surrounding wall 31 defines an opening 350. Each of the webs 32 extends between the open ends 35 of the surrounding wall 31. Each of the cells 30 extends in the horizontal direction (Z). The shoe sole further includes an elastic film 33 that is attached to one of the open ends 35 of the surrounding wall 31 so as to cover the opening 350 of said one of the open ends 35 of the surrounding wall 31.
  • In this embodiment, the surrounding wall 31 has a curved upper wall portion 311 and a curved lower wall portion 312 connected end-to-end to the upper wall portion 311. The webs 32 are grouped into substantially parallel first webs 32 and substantially parallel second webs 32 that extend in a direction opposite to that of the first webs 32 and that intersect the first webs 32 to form the cells 30. Preferably, each of the webs 32 is inclined relative to the upper and lower wall portions 311, 312 of the surrounding wall 31 such that a top vertex angle θ of each of the cells 30 is greater than 90 degrees.
  • FIG. 5 illustrates the first preferred embodiment disposed in a compressed state. By virtue of the cellular structure, the compressibility of the elastic body 3 in the compression direction (Y) toward the ground is enhanced as compared to the aforesaid conventional shoe sole, and the elastic body 3 can be easily deformed by a downward force (F), thereby enhancing the shock absorbing effect. At the compressed state, the top vertex angle θ is enlarged as a result of the downward force (F).
  • FIG. 6 illustrates the second preferred embodiment of the shoe sole according to this invention. The shoe sole differs from the previous embodiment in the cellular structure of the elastic body 3. The cellular structure of the elastic body 3 of this embodiment has four levels of the cells 30. Each level includes different sizes of the cells 30. The different sizes of the cells 30 of the four levels are arranged in a staggered manner.
  • FIG. 7 illustrates the third preferred embodiment of the shoe sole according to this invention. The shoe sole differs from the previous embodiments in the cellular structure of the elastic body 3.
  • FIG. 8 illustrates the fourth preferred embodiment of the shoe sole according to this invention. The shoe sole of this embodiment differs from the previous embodiments in that the shoe sole of this embodiment includes two elastic bodies 3 and that the sole unit 2 is formed with two recesses 20, each of which receives a respective one of the elastic bodies 3. One of the recesses 20 is disposed adjacent to a toe portion of the shoe sole, while the other of the recesses 20 is disposed adjacent to the heel portion of the shoe sole.
  • FIG. 9 illustrates the fifth preferred embodiment of the shoe sole according to this invention. The shoe sole of this embodiment differs from the previous embodiments in that the recess 20 in the outsole 21 of this embodiment extends from the heel portion to the toe portion of the shoe sole.
  • FIG. 10 illustrates the sixth preferred embodiment of the shoe sole according to this invention. The shoe sole of this embodiment differs from the previous embodiments in that the recess 20 substantially spans two lateral sides of the heel portion of the shoe sole.
  • By virtue of the cellular structure of the elastic body 3, which includes multi-level cells 30 disposed one above the other, the shoe sole of this invention can enhance the compressibility in the compression direction (Y) toward the ground as compared to the aforesaid conventional shoe sole.
  • While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
