Shoes and sneakers having hydromagnetic joints

Abstract

A shoe or sneaker includes a hydromagnetic joint having a first joint part including a first magnetic element having a first magnetically charged surface, and a first buoyant element coupled with the first magnetic element. The first buoyant element overlies a surface of the first magnetic element that is opposite the first magnetically charged surface. The shoe includes a second joint part including a second magnetic element having a second magnetically charged surface that opposes the first magnetically charged surface of the first magnetic element, and a second buoyant element coupled with the second magnetic element. The second buoyant element overlies a surface of the second magnetic element that is opposite the second magnetically charged surface. A liquid is disposed between the first and second joint parts. The first and second joint parts are moveable relative to one another and are in fluid communication with the liquid.

         2 . The shoe as claimed in  claim 1 , wherein said liquid is contained within an enclosure that is disposed between said first and second joint parts. 
     
     
         3 . The shoe as claimed in  claim 2 , wherein said enclosure for said liquid is flexible. 
     
     
         4 . The shoe as claimed in  claim 1 , wherein at least one of said first and second joint parts comprises a solid body having at least one aperture extending therethrough adapted for enabling said liquid to pass through said at least one aperture. 
     
     
         5 . The shoe as claimed in  claim 4 , wherein said at least one aperture comprises a plurality of apertures. 
     
     
         6 . The shoe as claimed in  claim 1 , wherein said first and second joint parts are moveable relative to one another. 
     
     
         7 . The shoe as claimed in  claim 6 , wherein said first and second joint parts are aligned with one another along an axis and are moveable relative to one another along the axis. 
     
     
         8 . The shoe as claimed in  claim 1 , wherein said first and second joint parts are adapted to move toward one another for compressing said liquid therebetween. 
     
     
         9 . The shoe as claimed in  claim 1 , wherein said first and second magnetically charged surfaces have the same polarity and are adapted to repel one another. 
     
     
         10 . The shoe as claimed in  claim 1 , wherein said shoe is a sneaker. 
     
     
         11 . The shoe as claimed in  claim 1 , wherein said shoe has a heel region and said hydromagnetic joint is incorporated into said heel region. 
     
     
         12 . A shoe comprising:
 an upper part of said shoe;   a lower part of said shoe;   a hydromagnetic joint incorporated into said lower part of said shoe;   said hydromagnetic joint comprising   a first part including a first magnetic element having a first magnetically charged surface and a first buoyant element coupled with said first magnetic element, wherein said first buoyant element overlies a surface of said first magnetic element that is opposite said first magnetically charged surface,   a second part including a second magnetic element having a second magnetically charged surface that opposes said first magnetically charged surface of said first magnetic element and a second buoyant element coupled with said second magnetic element, wherein said second buoyant element overlies a surface of said second magnetic element that is opposite said second magnetically charged surface, and   a liquid body disposed between said first and second parts, wherein said liquid is disposed between said first and second magnetic elements which, in turn, are disposed between said first and second buoyant elements, respectively, and wherein said first and second parts are in fluid communication with said liquid body and are adapted to move relative to one another.   
     
     
         13 . The shoe as claimed in  claim 12 , wherein said lower part of said shoe includes a heel region, and wherein said hydromagnetic joint is incorporated into said heel region. 
     
     
         14 . The shoe as claimed in  claim 13 , wherein said first and second magnetically charged surfaces have a common polarity so that said first and second magnetically charged surfaces repel one another. 
     
     
         15 . The shoe as claimed in  claim 14 , further comprising an enclosure extending between said first and second parts for containing said liquid body. 
     
     
         16 . The shoe as claimed in  claim 15 , wherein said enclosure is flexible for changing shape as said first and second parts move relative to one another. 
     
     
         17 . The shoe as claimed in  claim 12 , wherein said shoe comprises a sneaker. 
     
     
         18 . A shoe comprising:
 a hydromagnetic joint including   a first joint part including a first buoyant element having a top surface and a bottom surface, a first magnetic element having a negatively charged top surface and a positively charged bottom surface, wherein said bottom surface of said first buoyant element overlies and is coupled with said negatively charged top surface of said first magnetic element,   a second joint part including a second buoyant element having a top surface and a bottom surface, a second magnetic element having a positively charged top surface and a negatively charged bottom surface, wherein said top surface of said second buoyant element overlies and is coupled with said negatively charged bottom surface of said second magnetic element, and wherein said positively charged top surface of said second magnetic element opposes said positively charged bottom surface of said first magnetic element, and   a liquid disposed between said positively charged bottom surface of said first magnetic element and said positively charged top surface of said second magnetic element, wherein said first and second joint parts are moveable relative to one another and are in fluid communication with said liquid.
