Abstract
This invention relates to a product built into the sole of a shoe that will cool and dehumidify one's feet, providing superior comfort to the feet of the person wearing the shoe. The invention comprises two layers, one of which has a liquid-filled area with a liquid powered turbine and the other layer containing a built-in air fan or fans or other turbines which are powered by the liquid turbine responding to the liquid movement in the other layer. These two layers are molded or otherwise connected to a shoe sole.
Claims6
A shoe sole, comprising:
- a top air ventilation section with holes in the top surface of the top section of the sole, said holes being in fluid communication with a hole in a side of the sole top section, and an air fan located in said top section, said air fan being in fluid communication with the hole in a side and in fluid communication with the holes in the top of said sole top section;
- a bottom fluid power section connected to said sole top section, said sole bottom section having a closed fluid power circuit comprising a front reservoir and front channel located near the front of said sole bottom section and a back reservoir and back channel located near the back of said sole bottom section, said front and back channels being connected to said front and back reservoirs, respectively, and said front and back channels being located nearer the center of said sole bottom section than said front and back reservoirs, and a fluid power turbine located between and in fluid communication with said front channel and said back channel;
- and
- drive means connecting said fluid power turbine to said air fan;
- wherein stepping on the front of the shoe sole will cause the wearer's toes and ball of foot to compress the front reservoir and drive fluid through the front channel, fluid power turbine and through the back channel to the back reservoir and, alternatively, stepping on the back of the shoe sole will cause the wearer's heel to compress the back reservoir and drive fluid through the back channel, fluid power turbine and through the front channel to the front reservoir, thereby driving the air fan.

A shoe sole, comprising:
- a first, fluid power collection section having a closed fluid power circuit comprising a front reservoir and front channel located near the front of said sole section and a back reservoir and back channel located near the back of said sole section, said front and back channels being connected to said front and back reservoirs, respectively, and said front and back channels being located between said front and back reservoirs, and a first rotating member comprising a fluid power collection turbine located between, and in fluid communication with, said front channel and said back channel;
- a second, power distribution section comprising a second rotating member comprising a power distribution shaft;
- and
- drive means connecting said first rotating member to said second rotating member;
- wherein stepping on the front of the shoe sole will cause the wearer's toes and ball of foot to compress the front reservoir and drive fluid through the front channel, through the first rotating member, the fluid power collection turbine, and through the back channel to the back reservoir and, alternatively, stepping on the back of the shoe sole will cause the wearer's heel to compress the back reservoir and drive fluid through the back channel, again through the first rotating member, and through the front channel to the front reservoir, thereby imparting angular momentum to the second rotating member, the power distribution shaft.
