Shoe, in Particular a Ski Boot, and Skiing Equipment

Abstract

A shoe contains an adjustable space for the foot and several fluidically connected chambers. In order to adjust the space for the foot, the flowability of a magnetorheological liquid can be influenced by at least one device generating a magnetic field thereby adjusting the space for the foot resulting in a better fitting of the shoe.

1 . A shoe, comprising:
 a variable foot area;   at least one device for producing a magnetic field;   deformable chambers with flow links connecting said deformable chambers to each other; and   a magnetorheological liquid having a capability to flow being influenced for varying said variable foot area by said at least one device for producing the magnetic field.   
   
   
       2 . The shoe according to  claim 1 , wherein said at least one device for producing the magnetic field is associated with said flow links. 
   
   
       3 . The shoe according to  claim 2 , wherein said least one device for producing the magnetic field is disposed adjacent to said flow links disposed between said deformable chambers. 
   
   
       4 . The shoe according to  claim 2 , further comprising a supply container for supplying said magnetorheological liquid, said at least one device for producing the magnetic field is disposed adjacent to said flow links disposed between said supply container and said deformable chambers. 
   
   
       5 . The shoe according to  claim 1 , wherein said at least one device for producing the magnetic field is one of a plurality of devices for producing the magnetic field, each of said flow links has an associated one said devices for producing the magnetic field. 
   
   
       6 . The shoe according to  claim 4 , wherein said flow links disposed between said deformable chambers and said supply container have said at least one device for producing the magnetic field being a common device for producing the magnetic field. 
   
   
       7 . The shoe according to  claim 2 , wherein said at least one device for producing the magnetic field has at least one permanent magnet. 
   
   
       8 . The shoe according to  claim 7 , wherein said permanent magnet is disposed to move relative to said flow links to attenuate or deactivate the magnetic field. 
   
   
       9 . The shoe according to  claim 8 , wherein said permanent magnet can be removed from the shoe. 
   
   
       10 . The shoe according to  claim 7 , wherein said permanent magnet has an associated moveable, magnetic shield to attenuate or deactivate the magnetic field. 
   
   
       11 . The shoe according to  claim 10 , wherein said magnetic shield can be removed from the shoe. 
   
   
       12 . The shoe according to  claim 11 , further comprising at least one motor for moving said magnetic shield. 
   
   
       13 . The shoe according to  claim 7 , wherein said permanent magnet has an associated switchable electromagnet to attenuate or deactivate the magnetic field of said permanent magnet. 
   
   
       14 . The shoe according to  claim 2 , wherein said device for producing the magnetic field has at least one switchable electromagnet. 
   
   
       15 . The shoe according to  claim 1 , wherein at least two of said deformable chambers contain said magnetorheological liquid at different pressures. 
   
   
       16 . The shoe according to  claim 1 , wherein said magnetorheological liquid is also contained in said deformable chambers. 
   
   
       17 . The shoe according to  claim 1 , wherein said flow links each have two sealing elements moveable within said flow links, said magnetorheological liquid in each of said flow links is enclosed by said two sealing elements and is separated from a different compound, which can flow, in said deformable chambers. 
   
   
       18 . The shoe according to  claim 1 , wherein each of said flow links has a constriction disposed approximately centrally in the magnetic field. 
   
   
       19 . The shoe according to  claim 1 , wherein the shoe is a ski boot. 
   
   
       20 . Skiing equipment, comprising:
 a ski with a ski binding;   a ski pole;   a ski boot, said ski boot including:
 a variable foot area; 
 at least one device for producing a magnetic field disposed adjacent to one of said ski binding said ski; 
 deformable chambers with flow links connecting said deformable chambers to each other; and 
 magnetorheological liquid having a capability to flow being influenced for varying said variable foot area by said at least one device for producing the magnetic field; and 
   a source for electrical energy disposed on one of said ski boot, said ski pole, said ski binding, and said ski.   
   
   
       21 . The skiing equipment according to  claim 20 , wherein said source has a generator for converting vibration movements into the electrical energy. 
   
   
       22 . The skiing equipment according to  claim 20 , further comprising a control system and at least one sensor.
