Shoe comprising an upper, an intermediate sole and a bottom support

Abstract

A shoe comprising an upper sole ( 11 ) receiving the user's foot, an intermediate sole ( 12 ), a bottom support ( 13 ) and linking mechanism ( 14 ) for detachably linking the bottom support ( 13 ) to the intermediate sole ( 12 ). The linking mechanism ( 14 ) comprise protuberances ( 15 ) inclined at an angle or relative to the vertical and designed to be inserted in recesses ( 16 ). The shoe further comprises a locking mechanism ( 19 ) formed by an elastic catch ( 21 ) co-operating with a locking rod ( 22 ). The elastic catch can be released from the locking rod to separate the intermediate sole ( 12 ) from the bottom support ( 13 ).

1 . A shoe consisting of an upper, an intermediate sole integral with said upper, and a bottom support detachably joined to the intermediate sole, said shoe further comprising a means for connecting the intermediate sole to the bottom support, said connecting means comprising at least one projection and at least one recess, each projection cooperating with a recess, characterized in that said projections ( 15 ) comprise an axis ( 17 ,  17 ′) forming a non-null angle α with the vertical ( 18 ) on a contact plane between the intermediate sole ( 12 ) and the bottom support ( 13 ).  
     
     
         2 . A shoe according to  claim 1  characterized in that it comprises at least two projections ( 15 ), the axes ( 17 ,  17 ′) of these projections being parallel to each other.  
     
     
         3 . A shoe according to  claim 1  characterized in that said projections ( 15 ) are essentially cylindrical in shape and in that their axis ( 17 ) is parallel to the generatrix of the cylinder.  
     
     
         4 . A shoe according to  claim 1  characterized in that said projections ( 15 ) are essentially truncated in shape and in that their axis ( 17 ) passes through the center of the base of the trunk of the cone and through the tip of a cone containing said projection.  
     
     
         5 . A shoe according to  claim 1  characterized in that said projections ( 15 ) are curved and in that their axis ( 17 ′) passes through their center of gravity and through their free end.  
     
     
         6 . A shoe according to  claim 1  characterized in that the angle between the axis ( 17 ,  17 ′) of each projection ( 15 ) and the vertical ( 18 ) on the contact plane between the intermediate sole ( 12 ) and the bottom support ( 13 ) ranges from 10° to 80°.  
     
     
         7 . A shoe according to  claim 1  characterized in that it comprises a means ( 19 ) to lock the intermediate sole ( 12 ) to the bottom support ( 13 ).  
     
     
         8 . A shoe according to  claim 7  characterized in that the means ( 19 ) for locking the intermediate sole ( 12 ) to the bottom support ( 13 ) comprises at least one flexible hook ( 21 ).  
     
     
         9 . A shoe according to  claim 8  characterized in that the flexible hook ( 21 ) is held by a flexible plate movable within a plane containing a straight line parallel to the axis ( 17 , 17 ′) of at least one of the projections ( 15 ).  
     
     
         10 . A shoe according to  claim 9  characterized in that it comprises a housing ( 23 ) cooperating with said flexible hook ( 21 ).  
     
     
         11 . A shoe according to  claim 10  characterized in that the housing ( 23 ) cooperating with said flexible hook ( 21 ) comprises a locking bar ( 22 ).  
     
     
         12 . A shoe according to  claim 8  characterized in that the flexible hook is removable.  
     
     
         13 . A shoe according to  claim 1  characterized in that the projections ( 15 ) are connected to the intermediate sole ( 12 ).  
     
     
         14 . A shoe according to  claim 1  characterized in that the projections ( 15 ) are connected to the bottom support ( 13 ).  
     
     
         15 . A shoe according to  claim 1  characterized in that the bottom support ( 13 ) is a sole.  
     
     
         16 . A shoe according to  claim 1  characterized in that the bottom support ( 13 ) is a sports board.  
     
     
         17 . A shoe according to  claim 1  characterized in that the bottom support ( 13 ) is a ski.  
     
     
         18 . A shoe according to  claim 1  characterized in that the bottom support ( 13 ) is a wheeled device.
