Interface device between a gliding board and a boot biding element

Abstract

An interface device between an element for binding a boot and a gliding or rolling board, the device including at least one longitudinally extended platform having a lower surface provided to be applied against the ski, and an upper surface provided for receiving at least one element for binding a boot. The platform has at least one set of transverse notches, the notches being made over the entire width or height of the platform and opening out onto two opposite surfaces of the platform, so that the plate has at least two platform blocks connected by an extensible and retractable connecting zone.

1 . An interface device for positioning between at least one binding element for a boot and a gliding or rolling board, said device comprising: 
 at least one longitudinally extending platform comprising: 
 a lower surface to be supported above the board;  
 an upper surface including at least one receiving zone for receiving at least one binding element for a boot;  
 at least one set of transversely extending notches;  
 said set of notches being made in said receiving zone over an entirety of the width or an entirety of the height of the platform;  
 said notches of said set of notches opening out on two opposite surfaces of said platform, thereby defining at least two platform blocks in said receiving zone of said platform, said two platform blocks thereby being connected by an extensible and retractable connecting zone.  
   
   
   
       2 . An interface device according to  claim 1 , wherein: 
 said set of notches comprises a series of notches alternately opening successively onto said two opposite surfaces of said platform.    
   
   
       3 . A interface device according to  claim 1 , wherein: 
 two adjacent notches of said set of notches are spaced apart by one centimeter or less than one centimeter.    
   
   
       4 . An interface device according to  claim 1 , wherein: 
 for a complete set of said set of notches, a bottom of each notch opening onto the upper surface of the platform is lower than a bottom of each notch opening onto the lower surface of said platform.    
   
   
       5 . An interface device according to  claim 1 , wherein: 
 said platform includes: 
 rows of housings to house screws for assembling said platform to the board; and  
 rows of holes for assembling a binding element to said platform;  
   each of said two platform blocks has at least one row of holes or at least one row of housings.    
   
   
       6 . An interface device according to  claim 1 , wherein: 
 said platform has an upper portion comprising opposite lateral extensions, said lateral extensions forming opposite lateral rails to guide a support plate of a binding element for adjustable movement to a fixed position on said platform;    said notches opening out on two opposite surfaces include notches opening out onto said upper surface of said platform;    said notches opening out onto said upper surface of said platform create discontinuities in said lateral extensions.    
   
   
       7 . An interface device according to  claim 1 , wherein: 
 said platform has a lower portion and anchoring pins extending from said lower portion to be nested within the board;    at least a respective one of said anchoring pins is associated with each of said platform blocks.    
   
   
       8 . An interface device according to  claim 1 , wherein: 
 said platform has two parallel arms;    each of said two parallel arms includes a plurality of said notches of said set of notches;    notches of said two parallel arms are aligned with one another.    
   
   
       9 . An interface device according to  claim 1 , wherein: 
 at least one set of said at least one set of notches connect said two platform blocks and comprises notches opening out onto a single one of said two opposite surfaces of said platform joined together to form a connecting arch between said two platform blocks, said connecting arch having a thickness reduced relative to a width of said platform.    
   
   
       10 . An interface device according to  claim 1 , wherein: 
 said upper surface of said longitudinally extending platform comprises a receiving zone for a front binding element, for securing a front of a boot onto the board, and a receiving zone for a rear binding element for securing a rear of a boot onto the board.    
   
   
       11 . An assembly comprising an interface device according  claim 1  in combination with at least one binding element for a boot, said binding element adapted to be fixed to said platform of said interface device.  
   
   
       12 . An assembly according to  claim 11 , wherein: 
 said binding element comprises a toe binding and/or a heel binding.    
   
   
       13 . An interface device for an alpine ski, adapted to be positioned between the ski and at least one binding for a boot, said interface device comprising: 
 at least one longitudinally extending platform comprising: 
 a lower surface to be supported above the board;  
 an upper surface including at least one receiving zone for receiving a toe binding and/or a heel binding for a boot;  
 at least one set of transversely extending notches;  
 said set of notches being made in said receiving zone over an entirety of the width or an entirety of the height of the platform;  
 said notches of said set of notches opening out on two opposite surfaces of said platform, thereby defining at least two platform blocks in said receiving zone of said platform, said two platform blocks thereby being connected by an extensible and retractable connecting zone.  
   
   
   
       14 . An assembly comprising an interface device according  claim 13  in combination with at least one of a toe binding and a heel binding, said toe and/or heel binding element adapted to be fixed to said platform of said interface device.  
   
   
       15 . An assembly according to  claim 14 , wherein: 
 said binding element has a greatest width greater than a greatest width of said platform.
