Safety device, for ski bindings

Abstract

A safety device, particularly usable in ski bindings including a lever-equipped button that is selectively and rotatably associated with a central body, constituted by a lever that has a first end, which is pivoted to the button, and a second free end, which interacts, by abutment, with at least one locator provided in the central body. The lever thus arranged acts as a device for the temporary locking of the rotation of the button.

What is claimed is:  
     
         1 . A safety device, particularly for ski bindings comprising a lever-equipped button that is selectively and rotatably associated with a central body, wherein it comprises a lever that has a first end, which is pivoted to said button, and a second free end, which interacts by abutment with at least one first locator provided in said central body for the temporary locking of the rotation of said button.  
     
     
         2 . The device according to  claim 1 , wherein said lever is pivoted to said lever-equipped button by means of a pivot that passes within one or more holes formed within said button and said first end of said lever.  
     
     
         3 . The device according to  claim 2 , wherein said central body has a first seat for positioning said button, which interacts in a lower region with a plurality of gears for activating a device for adjusting said binding, an elastically deformable element being associated with said lever and being adapted to keep it in abutment and accommodated within a second seat, which is formed in said button and is shaped complementarily to a first inner lateral edge of said lever.  
     
     
         4 . The device according to  claim 3 , wherein said elastically deformable element is constituted by a cylindrical spring arranged coaxially to said pivot.  
     
     
         5 . The device according to  claim 4 , wherein said lever-equipped button is arranged laterally to said central body, said pivot passing approximately vertically through two first holes formed in said first end of said lever and through a second hole formed at the end of the button that is directed toward the outer lateral edge of said central body.  
     
     
         6 . The device according to  claim 5 , wherein said lever-equipped button assumes a first locking position, in which it is accommodated within said first seat, and a second position for activating said adjustment device, in which said button protrudes approximately at right angles to said ski, when said button is in the locking position said lever being arranged approximately parallel to the longitudinal axis of said ski and being accommodated within said second seat.  
     
     
         7 . The device according to  claim 6 , wherein when said button is arranged in the locking position, said second end of said lever is shaped so as to interact by abutment with said first locator provided in said central body.  
     
     
         8 . The device according to  claim 7 , wherein said first locator is constituted by a portion of the raised edge that constitutes said first seat.  
     
     
         9 . The device according to  claim 8 , wherein the interposition of parts between said first locator and said lever, arranged in abutment, ensures the temporary locking of the rotation of said button.  
     
     
         10 . The device according to  claim 9 , wherein the second lateral edge of said lever, which is external and opposite with respect to said first lateral edge, has an approximately linear shape that is suitable to arrange itself approximately on the same plane as the lateral edge of said ski when said is lever is in the abutment position.  
     
     
         11 . The device according to  claim 10 , wherein once said lever has been turned so that said second end does not interact with said first locator, the user can turn said lever-equipped button until it reaches the second activation position.  
     
     
         12 . The device according to  claim 11 , wherein when said button is arranged in the activation position, said elastically deformable element forces said lever to assume a position that is approximately parallel to the longitudinal axis of said ski, so that said second end of said lever interacts with a second locator provided along the lateral edge of said central body.  
     
     
         13 . The device according to  claim 12 , wherein when said button is arranged in the activation position, said lever, by protruding laterally and externally from said ski, acts as a visual indicator of the activation position of said button.
