Sports shoe such as a ski boot or suchlike

Abstract

A sports shoe comprising a lower part which contains the user's foot, an upper part pivoted on the lower part to contain the ankle joint, and a clamping device that selectively clamps the upper part with respect to the lower part. The clamping device comprises a command mechanism mounted at least partly outside on the upper part, and at least a lever element pivoted on the lower part and selectively moved by the command mechanism between a first clamped position, in which the lever element cooperates with the upper part, in order to keep the upper part in a determinate clamped position with respect to the lower part, and a second released position, in which the lever element allows the upper part to oscillate freely with respect to the lower part.

1 . Sports shoe comprising a lower part, able to contain the user's foot, an upper part pivoted on said lower part and able to contain the ankle joint, and a clamping device able to selectively clamp said upper part with respect to said lower part, wherein said clamping device comprises a command mechanism mounted at least partly outside on said upper part, and at least a lever element pivoted on said lower part and able to be selectively moved by said command mechanism between a first clamped position, in which said lever element cooperates with said upper part, in order to keep said upper part in a determinate clamped position with respect to said lower part, and a second released position, in which said lever element allows said upper part to oscillate freely with respect to said lower part. 
   
   
       2 . The sports shoe as in  claim 1 , wherein said command mechanism is pivoted to said upper part at a point substantially opposite the pivoting point of said lever element on said lower part, with respect to the zone of cooperation between said lever element and said upper part in said first clamped position. 
   
   
       3 . The sports shoe as in  claim 1 , wherein said command mechanism comprises a first lever at least partly external to said upper part and a second lever articulated to an end of said first lever, pivoted to said upper part and able to contact said lever element, so as to take said lever element selectively between said first clamped position and said second released position. 
   
   
       4 . The sports shoe as in  claim 3 , wherein the pivoting point of said second lever to said upper part is substantially opposite the pivoting point of said lever element to said lower part, with respect to the contact point between said first lever and said lever element. 
   
   
       5 . The sports shoe as in  claim 3 , wherein said first lever is positioned substantially above said second lever and has a gripping end shaped towards the outside in order to facilitate the user's grip. 
   
   
       6 . The sports shoe as in  claim 3 , wherein said first lever of said command mechanism comprises an external surface at least partly shaped so as to guarantee that the articulation dead point between said first lever and said second lever is surpassed, in a limit position of rotation in opening of said first lever. 
   
   
       7 . The sports shoe as in  claim 1 , wherein said upper part internally comprises a stop surface, against which said lever element is able to rest in said first clamped position. 
   
   
       8 . The sports shoe as in  claim 1 , wherein said clamping device comprises an elastic element operationally connected to the lever element in order to keep the latter normally in said first clamped position.
