Abstract

A shoe sole is composed of particles of Ethylene Vinyl Acetate and the particles are connected with each other with gaps defined between the particles so as to form irregular surface of the shoe sole. The sole is made by filling the particles to 77% to 87% of volume of a cavity in a mold set, wherein an angle 40 to 50 degrees is clamped between a spinning axis of the cavity and an axis to which the mold set is rotated about. The mold set is then heated to 140 to 160 degrees Celsius and spins the mold set about the spinning axis 22 to 32 minutes. After cooling the mold set, the shoe sole is formed and is removed from the cavity.

Description

    FIELD OF THE INVENTION
  • [0001]
    The present invention relates to a shoe sole composed of particles of EVA and the particles are connected with each other with gaps defined therebetween so that the sole is light in weight and has good ventilation feature.
  • BACKGROUND OF THE INVENTION
  • [0002]
    A conventional shoe sole such as the sole of sandals is made of rubber or foam material which is a solid structure and does not have any ventilation feature. The foam material can be injected to be the shoe sole which includes a flat bottom and upper surface. This conventional shoe sole tends to trap sweater or damp on the surface where the wearer's foot steps on. Besides, the rubber made shoe sole is heavy and does not provide satisfied ventilation either.
  • [0003]
    The present invention intends to provide a shoe sole that includes gaps defined between the particles so as to drain water and provides a good ventilation feature.
  • SUMMARY OF THE INVENTION
  • [0004]
    The present invention relates to shoe sole includes an irregular outer surface which includes gaps defined between the particles of the material of the sole. The method for making the sole includes the following the steps:
      • step 1: preparing short and cylindrical particles:
      • step 2: filling the particles to 77% to 87% of volume of a cavity in a mold set, an angle 40 to 50 degrees clamped between an axis of the cavity and a spinning axis to which the mold set is rotated about;
      • step 3: heating the mold set to 140 to 160 degrees Celsius and spinning the mold set 22 to 32 minutes, and
      • step 4: cooling the mold set and removing a shoe sole from the cavity.
  • [0009]
    The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • [0010]
    FIG. 1 shows the steps of the method for making the shoe sole of the present invention;
  • [0011]
    FIG. 2 shows the particles are filled in the cavity of the mold set;
  • [0012]
    FIG. 3 shows the shoe sole of the present invention;
  • [0013]
    FIG. 4 shows the particles are heated and filled in the cavity of the mold set, and
  • [0014]
    FIG. 5 is an enlarged view to show the arrangement of the particles of the shoe sole.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • [0015]
    Referring to FIGS. 1 to 3, the method for making the shoe sole 30 of the present invention comprises the following steps which are:
  • [0016]
    Step 1: Preparing Material
  • [0017]
    Short and cylindrical particles 10 made of Ethylene Vinyl Acetate for example are prepared.
  • [0018]
    Step 2: Filling in Cavity of Mold Set
  • [0019]
    The particles 10 are filled to 77% to 87% of volume of a cavity 21 in a mold set 20, and an angle 40 to 50 degrees is clamped between an axis 22 of the cavity 21 and a spinning axis 23 to which the mold set 20 is rotated about.
  • [0020]
    Step 3: Forming Process
  • [0021]
    The mold set 20 is heated up to 140 to 160 degrees Celsius and spun for 22 to 32 minutes as disclosed in FIG. 4.
  • [0000]
    Step 4: Cooling and Removing the Shoe Sole
  • [0022]
    The mold set 20 is cooled and a shoe sole 30 is removed from the cavity 21.
  • [0023]
    Referring to FIGS. 3 and 5, the particles 10 are spread and filled in the cavity 21 due to the eccentric force when the mold set 20 spins and the particles 10 are expanded and connected with each other at the contact areas therebetween by way of fusion. Because the particles 10 are filled only 77% to 87% of volume of the cavity 21 of the mold set 20, there will be gaps 32 defined between the particles 10 and the sole 30 includes an irregular outer surface 31. The shoe sole is light in weight and easily to manufacture. Besides, the irregular and uneven outer surface 31 of the shoe sole 30 allows damp and water to be escaped when the sole 30 is in use.
  • [0024]
    While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.

    step 3: heating the mold set to 140 to 160 degrees Celsius and spinning the mold set for 22 to 32 minutes, and
    step 4: cooling the mold set and removing a shoe sole from the cavity.
