    2. Description of Related Art
  • [0004]
    A conventional shoe includes an insole having front vent holes; and an outsole including a heel having an open cavity, a first check valve extending from the cavity to the external, and a flexible protrusion on the heel bottom; a cover fitted on the cavity and including grooves and a second check valve communicating with the grooves and the cavity; front projections on the insole top; and a channel on the arch top. Foot stepping compresses the protrusion to close the first check valve and open the second check valve such that air within the cavity is expelled to a insole of the foot via the second check valve, the grooves, the channel, and the vent holes. Foot lifting returns the protrusion to its original shape with the first check valve open and the second check valve closed, thereby drawing air into the cavity.

  • DETAILED DESCRIPTION OF THE INVENTION
  • [0034]
    Referring to FIGS. 1 to 4, a multi-function ventilated insole 1 in accordance with the invention comprises the following components as discussed in detail below.
  • [0035]
    An elastic airbag 2 is disposed on the heel of the insole 1 and the said elastic airbag 2 includes a top layer section 23, a bottom layer section 24 and an air chamber 3 forming between the top layer section 23 and the bottom layer section 24. A check valve 20 and an integral inlet 10 are disposed on the rear of the elastic airbag 2 and both are communicated each other with the air chamber 3. Two outlets 21 is formed on the front of the elastic airbag 2 and communicated with the air chamber 3. The said top layer section 23, a bottom layer section 24, air chamber 3, check valve 20, inlet 10, and two outlets 21 are integrally formed with the elastic airbag 2. The air chamber 3 is formed of a flexible material the same as that of the top layer section 23 but having a different hardness. For example, the top layer section 23 has a hardness of 30-35, and the bottom layer section 24 has a hardness of 50-55 are formed as a dual density unit.
  • [0036]
    Two spaced channels 11 each extend from the elastic airbag 2 to a plantar arch portion 4 of the insole 1. The channel 11 includes a plurality of vent holes 12 disposed from a front end to an intermediate portion, and a rear concealed tunnel 110 extending to communicate with one of two outlets 21 to the air chamber 3 and the check valve 20.
  • [0037]
    An oval, flexible main support 22 is disposed in the air chamber 3 and connected to the top layer section 23 and bottom layer section 24. Two spaced flexible auxiliary supports 25 are disposed in the air chamber 3 and connected to the top layer section 23 and the bottom layer section 24 and formed on one side of the flexible main support 22 respectively. The main support 22 and the auxiliary supports 25 are integrally formed. The main support 22 and the auxiliary supports 25 are formed of a flexible material which has hardness less than that of the bottom layer section 24.
  • [0038]
    The ventilation effect of the invention will be described in detail below. The elastic airbag 2 is compressed when a wearer's foot wearing the shoe puts the most pressure down on the insole 1 in a stepping action of walking. And in turn, the main support 22 and the auxiliary supports 25 are flexibly compressed and the space of the air chamber 3 is reduced. The pressurized air within the air chamber 3 forces the check valve 20 to close. Also, this forms a mechanism that expels air from within the air chamber 3 to the vent holes 12 via the outlet 21, the tunnels 110, and the channels 11. As a result, foul air is expelled out of the insole 1 via the vent holes 12.
  • [0039]
    The elastic airbag 2 is expanded to return to its original shape when the person lifts his or her feet in a lifting action of walking. And in turn, both the main support 22 and the auxiliary supports 25 return to its original shape. The air pressure within the air chamber 3 decreases sharply. This means that the air pressure within the air chamber 3 is less than the atmospheric pressure. Further, this forms a mechanism that draws atmospheric air into the air chamber 3 via the inlet 10 of the open check valve 20. At about the same time, air inside of insole 1 trapped is drawn into the air chamber 3 via the vent holes 12, the channels 11, the tunnels 110, and the outlet 21. As a result, the air chamber 3 returns to its original state.
  • [0040]
    Weight of the wearer can be sufficiently supported by both the main support 22 and the auxiliary supports 25 return to its original shape. Thus, a ventilation effect to the insole 1 is carried out by repeating the stepping and lifting actions of the foot in walking. As a result, breathability of the shoe greatly increases and unpleasant odors no longer exist.
  • [0041]
    A plurality of recesses 13 are formed on top of a front portion of the insole 1 corresponding to the toes of the foot of a wearer. Each recess 13 has a knob 14 on a central portion of its top. A curve protrusion 15 is formed on the top of the insole 1 proximate to the recesses 13. A heart shaped protuberance 17 is formed on the top of insole 1 between the front ends of the channels 11. A cavity 16 is formed on the top of the insole 1 between the protrusion 15 and the protuberance 17. Thus, a wearer can feel a degree of comfort on the feet when wearing shoes incorporating the insole of the invention.
  • [0042]
    As shown in FIG. 5 specifically, the bottom layer section 24 is formed as a part of outsole 5. It is envisaged by the invention that ventilation, shock absorbing, foot massaging, anti-slippery, and steadying walk are brought about to the feet while walking.
  • [0043]
    The invention further has the following advantages:
      • 1. Shock absorbing to the feet is obtained due to the provision of the main support and the auxiliary supports by flexibly returning to its original shape after lifting the foot.
      • 2. Check valve is provided on the heel so that fresh air can be drawn into the shoe and foul air can be expelled via outlet in the heel. As a result, ventilation is achieved.
      • 3. In response to a wearer's foot stepping on the insole, the main support, the auxiliary supports, and the elastic airbag are compressed, pressure of air in the elastic airbag increases to close the check valve, and draw the air from the elastic airbag to the vent holes via the outlet, the tunnels, and the channels, thereby expelling the air. In response to the wearer's foot lifting the sole, the main support, the auxiliary supports, and the elastic airbag return to its original shape, draw atmospheric air into the elastic airbag via the check valve, and draw air above the insole into the elastic airbag via the vent holes, the channels, the tunnels, and the outlet. As a result, foot hygiene can be obtained by sufficiently ventilating the air inside of shoe.
      • 4. The at least one recessed and raised portions from a front end to an intermediate portion of the insole can increase traction and comfort while walking in addition to the wearer's foot massaging.
      • 5. The bottom layer section can be formed as a part of outsole. It is envisaged by the invention that ventilation that ventilation, shock absorbing, foot massaging, anti-slippery, and steadying walk are brought about to the feet while walking.
  • [0049]
    While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
