Braking device for a binding for a gliding board

Abstract

A braking device for a gliding board, such as a ski, that includes a plate adapted to be fixed on an upper surface of the gliding board; two braking arms movable between a gliding position and a braking position; and two flanges, each guiding a braking arm. Each flange is rotationally movable in relation to the plate about separate axes of rotation.

1 . A braking device for gliding board, comprising:
 a plate adapted to be fixed on an upper surface of the gliding board;   two braking aims movable between a gliding position and a braking position;   two flanges each guiding a braking arm;   the two flanges being rotationally movable in relation to the plate about separate axes of rotation.   
     
     
         2 . A braking device according to  claim 1 , wherein:
 the axes of rotation of the flanges are substantially perpendicular to the upper surface of the gliding board in the assembled configuration of the braking device on the gliding board.   
     
     
         3 . A braking device according to  claim 1 , further comprising:
 a removable assembly element structured and arranged to rotationally lock the two flanges in relation to the plate in at least one assembly position.   
     
     
         4 . A braking device according to  claim 1 , wherein:
 the braking arms are guided by the flanges, so that a transverse distance between the arms in the braking position, measured perpendicular to a longitudinal median plane of the braking device, varies depending upon the angular position of the flanges around their respective axes of rotation.   
     
     
         5 . A braking device according to  claim 1 , wherein:
 the flanges are coplanar blades.   
     
     
         6 . A braking device according to  claim 3 , wherein:
 the assembly element comprises at least two first indexing mechanisms structured and arranged to cooperate respectively with at least one first complementary indexing mechanism arranged on each flange when the braking device is in the assembled configuration.   
     
     
         7 . A braking device according to  claim 3 , wherein:
 the assembly element comprises at least one second indexing mechanism structured and arranged to cooperate with at least one second complementary indexing means arranged on the plate when the braking device is in the assembled configuration.   
     
     
         8 . A braking device according to  claim 1 , wherein:
 a first flange of the two flanges comprises a movement transfer mechanism;   a second flange of the two flanges comprises a complementary movement transfer mechanism;   the movement transfer mechanism cooperates with the complementary movement transfer mechanism when the braking device is assembled, so that rotation in a direction of the first flange about a respective axis of rotation causes rotation in an opposite direction of the second flange about a respective axis of rotation.   
     
     
         9 . A braking device according to  claim 3 , wherein:
 the assembly element comprises at least two lateral stop surfaces arranged on respective ones of both sides of a center line;   each of the two flanges comprises at least one abutment surface arranged to be opposite a lateral stop surface in at least one assembly position of the assembly element.   
     
     
         10 . A braking device according to  claim 1 , wherein:
 in an assembly position of the assembly element, a lateral stop surface and an abutment surface of a corresponding flange are generally in contact.   
     
     
         11 . An assembly comprising:
 a binding for binding a boot to a gliding board;   a braking device for the gliding board, the braking device comprising:
 a plate adapted to be fixed on an upper surface of the gliding board; 
 two braking arms movable between a gliding position and a braking position; 
 two flanges each guiding a braking arm; 
 the two flanges being rotationally movable in relation to the plate about separate axes of rotation. 
   
     
     
         12 . An assembly comprising:
 a gliding board;   a braking device for the gliding board, the braking device comprising:
 a plate adapted to be fixed on an upper surface of the gliding board; 
 two braking arms movable between a gliding position and a braking position; 
 two flanges each guiding a braking arm; 
 the two flanges being rotationally movable in relation to the plate about separate axes of rotation. 
   
     
     
         13 . An assembly according to  claim 12 , further comprising:
 a binding for binding a boot to the gliding board.
