Clamp for ski boots and similar

Abstract

A clamp for ski boots and similar, having a supporting plate fixed rigidly to a first portion of the outer shell of the boot; a lock lever hinged at one end to the supporting plate; and a lock arm having a first end hinged to slide freely along a central portion of the body of the lock lever, and a second end shaped to engage an anchoring plate fixed rigidly to a second portion of the outer shell of the boot.

1 ) A clamp ( 1 ) for ski boots and similar, comprising a supporting plate ( 2 ) fixed to the outer shell of the boot; a lock lever ( 3 ) hinged at a first end ( 3   a ) to said supporting plate ( 2 ); and a lock arm ( 4 ) fixed at a first end ( 4   a ) to said lock lever ( 3 ); said clamp ( 1 ) being characterized in that the first end ( 4 a) of said lock arm ( 4 ) is hinged to slide freely along a central portion ( 3   b ) of the body of said lock lever ( 3 ).  
     
     
         2 ) A clamp as claimed in  claim 1 , characterized in that said lock lever ( 3 ) comprises, at the central portion ( 3   b ) of its body, at least one contoured slot ( 8 ); and the first end ( 4   a ) of said lock arm ( 4 ) is mounted to slide freely inside said at least one contoured slot ( 8 ).  
     
     
         3 ) A clamp as claimed in  claim 1 , characterized in that the first end ( 3   a ) of said lock lever ( 3 ) is hinged to a pair of flat brackets ( 2   a ) projecting from said supporting plate ( 2 ), so as to rotate freely about a first axis of rotation (A) perpendicular to the mid-plane (M) of the lock lever.  
     
     
         4 ) A clamp as claimed in  claim 3 , characterized in that said lock lever ( 3 ) has a central opening ( 6 ) extending from said first end ( 3   a ) of the lock lever inwards of the body of the lock lever, and parallel to the mid-plane (M).  
     
     
         5 ) A clamp as claimed in  claim 4 , characterized in that said lock arm ( 4 ) is divided into two longitudinal portions ( 9 ,  11 ); and the longitudinal portion ( 9 ) comprising the first end ( 4   a ) of said lock arm ( 4 ) is shaped to engage and slide along said central opening ( 6 ).  
     
     
         6 ) A clamp as claimed in  claim 4 , characterized in that said central opening ( 6 ) divides the first end ( 3   a ) of said lock lever ( 3 ) into two parallel facing appendixes, each having a respective contoured slot ( 8 ); the two contoured slots ( 8 ) being located on opposite sides of the mid-plane (M) of the lock lever and aligned with each other; and the longitudinal portion ( 9 ) of the lock arm ( 4 ) comprising the first end ( 4   a ) of the lock arm having a pair of pins ( 10 ) extending on opposite sides of the body of said longitudinal portion ( 9 ), so as each to engage and slide along a respective contoured slot ( 8 ).  
     
     
         7 ) A clamp as claimed in  claim 1 , characterized in that said lock arm ( 4 ) has a second end ( 4   b ) shaped to rapidly engage and easily release an anchoring plate ( 5 ) also fixed to the outer shell of said boot.
