Shoe Having Active Air Ventilation

Abstract

The invention relates to a shoe, comprising a sole construction, which has an upper sole part and a lower outsole part and an air-pumping device having a pumping vol-ume, an air-supplying device, which is connected to the air-pumping device, an air-discharging device, which is connected to the air-pumping device, wherein the upper sole part, the lower outsole part, and the air-pumping device are de-signed in such a way that air in the amount of the pumping volume can be sucked into the air-pumping device through the air-supplying device from outside the shoe and above the upper sole part due to the unloading of the sole con-struction during the walking motion of a user, air in the amount of the pumping volume can be discharged into the interior of the shoe through the air-discharging device due to the loading of the sole construction during the walking motion of the user, and the pumping volume of the air-pumping device is at least 5 ml, in particular at least 10 ml.

1 . Shoe with
 a sole construction having an upper sole part, a lower outsole part and an air-pumping device,   where said air-pumping device is formed either by a cavity substantially embedded in said upper sole part or formed separately as an independent entity fully or partially embedded in a cavity of said upper sole part;   an air-supplying device which is connected to said air-pumping device,   an air-discharging device which is connected to said air-pumping device,   wherein said upper sole part, said lower outsole part, and said air-pumping device are configured in such a way that
 air can from outside said shoe and above said upper sole part be sucked into said air-pumping device by said air-supplying device due to the unloading of said sole construction during the walking motion of a user, 
 air can be discharged into the interior of said shoe by said air-discharging device due to the loading of said sole construction during the walking motion of the user, and said air-pumping device can there be compressed by a pumping volume corresponding to the amount of air discharged, 
 where said pumping volume is at least 5 ml, in particular at least 10 ml. 
   
     
     
         2 . Shoe according to  claim 1  in which air guides, in particular channels or mesh fabric, are formed in said sole construction and are connected to said air-pumping device. 
     
     
         3 . Shoe according to  claim 2 , where said air guides are formed in said upper sole part. 
     
     
         4 . Shoe according to  claim 2  in which said air guides are channels and openings are provided along said channels such that air flowing through said channels can be discharged through said openings into the interior of said shoe. 
     
     
         5 . Shoe according to  claim 1  in which openings are provided in said upper sole part through which air can be discharged info the interior of said shoe. 
     
     
         6 . Shoe according to  claim 2  comprising plastic tubes which are arranged in said air guides, where said plastic tubes comprise openings along their longitudinal axes. 
     
     
         7 . Shoe according to  claim 1 , wherein a valve is arranged in said air-supplying device such that air can be sucked into said air-pumping device only in the direction from the outside of said shoe and above said upper sole part; and/or
 a valve is arranged in said air-discharging device which is configured such that air can be discharged from said air-pumping device into the interior of said shoe.   
     
     
         8 . Shoe according to  claim 1 , in which a directional valve is provided such that air can in a first direction of opening of said directional valve be sucked into said air-pumping device from the outside of said shoe and above said upper sole part and air can in a second direction of opening of said directional valve be discharged from said air-pumping device into the interior of said shoe. 
     
     
         9 . Shoe according to  claim 1  in which said air-pumping device is formed in a portion of said upper sole part and at least this portion is configured more resilient than said lower outsole part. 
     
     
         10 . Shoe according to  claim 1  in which said lower outsole part at an outer tread area in the region of said air-pumping device comprises a raised portion which is adapted to be pressed in the direction of said upper sole part when being loaded by the user's foot. 
     
     
         11 . Shoe according to  claim 1  in which said upper sole part and said lower outsole part are formed separately. 
     
     
         12 . Shoe according to  claim 1  in which said upper sole part and said tower outsole part are formed integrally together, in particular as an injection-molded part. 
     
     
         13 . Shoe according to  claim 1  in which said air-pumping device is formed by a cavity which is substantially embedded in said upper sole part and which is filled with elastic filling material permeable to air. 
     
     
         14 . Shoe according to  claim 1  in which said air-pumping device is provided in the heel region or in the joint region of said shoe. 
     
     
         15 . Shoe according to  claim 1  in which said air supply is provided by use of a heel part attached by injection molding. 
     
     
         16 . Shoe according to  claim 1  further with an upper tor slipping in a foot of a user of said shoe, where said upper comprises a sole construction proximal part and a sole construction distal part, and in which said air-supplying device extends from said proximal part to said distal part partially along said upper, in particular, separated by an inner lining of said upper from said foot of the user of said shoe, such that air from said distal part can be pumped into said air-pumping device.
