Leg support particularly for snowboard bindings

Abstract

A leg support, for snowboard bindings, comprising a base to be fixed to a snowboard and from which a heel unit protrudes to the rear, the support comprising: a first vertically elongated plate element arc-like shaped in a lower region, with ends pivoted to the heel unit; a second vertically elongated arc-shaped plate element forming a calf support and arranged in front of the first element, by at least one first adjustable fixing assembly, engaging in a corresponding hole formed in the first element and slideable transversely in a first hole formed in the second element; at least one second adjustable fixing assembly, engaging in a corresponding hole formed in the first element and slideable in a second hole formed in the second element; so as to allow, when the first and second fixing assemblies are loosened, a translational motion of the second element with respect to the first element, substantially on the plane of arrangement of the first and second shaped holes.

What is claimed is:  
     
         1 . A leg support, particularly for snowboard bindings, of the type that comprises a base to be fixed to a snowboard and from which an arc-shaped heel unit protrudes to the rear, further comprising: 
 a first vertically elongated plate-like element that has an arc-like shape in a lower region, with ends pivoted to said heel unit;    a second vertically elongated arc-shaped plate-like element that forms a calf support and is arranged in front of said first element with respect to a heel-toe direction of the foot, by means of    at least one first adjustable fixing assembly, which engages in a corresponding calibrated hole formed in said first element and can slide transversely in a first shaped hole formed in said second element; and    at least one second adjustable fixing assembly, which engages in a corresponding calibrated hole formed in said first element and can slide in a second shaped hole formed in said second element;    so as to allow, when said first and second fixing assemblies are loosened, a translational motion of said second element with respect to said first element, substantially on the plane of arrangement of said first and second shaped holes.    
     
     
         2 . The leg support according to  claim 1 , wherein said second element comprises a rigid body and a front padding.  
     
     
         3 . The leg support according to  claim 2 , wherein said first hole is slotted, is elongated longitudinally so as to match said second element, and is formed in said rigid body of the second element.  
     
     
         4 . The leg support according to  claim 2 , wherein said second hole is substantially square so as to form a space for sliding on its own plane of arrangement and is formed in said rigid body of the second element.  
     
     
         5 . The leg support according to  claim 2 , wherein said first adjustable fixing assembly comprises a first internally threaded bush in which a first screw is engaged, with a base that is provided with two flanges that retain it so that it slides, without being able to escape, along said first hole, said lower flange being arranged within a first interspace formed between said rigid body and said padding of the second element.  
     
     
         6 . The leg support according to  claim 5 , wherein said second adjustable fixing assembly comprises a second internally threaded bush in which a second screw is engaged, said screw being provided with a flanged base that is arranged within a second interspace formed between said rigid body and said padding of the second element, said flanged base being larger than said second hole.  
     
     
         7 . The leg support according to  claim 6 , further comprising a third plate-like element that is arranged behind said first element with respect to said second element.  
     
     
         8 . The leg support according to  claim 7 , wherein said first screw is provided with a flanged head that rests on said third element, said first bush and said first screw passing through corresponding calibrated holes formed respectively in said third element and in said first element.  
     
     
         9 . The leg support according to  claim 8 , wherein a cover is hinged in an upper region on the head of said first screw and allows, once open, to actuate the rotation of said first screw.  
     
     
         10 . The leg support according to  claim 7 , wherein said second screw has a head that rests on said third element in opposition to said flanged base of said second bush, said second bush and said second screw passing through corresponding calibrated holes formed respectively in said third element and in said first element.
