Gliding or rolling board

Abstract

A gliding or rolling board having, from a first end to a second end, a first end zone, a central zone, and a second end zone. The board has in height at least a first reinforcement. In the central zone, at least one of the reinforcements has at least a portion whose structure is mechanically weakened with respect to the rest of the reinforcement structure.

1 . A gliding or rolling board comprising: 
 a first end and a second end;    a length measured along a longitudinal direction between said first and second ends;    a first edge and a second edge;    a width measured along a transverse direction between the first and second edges;    a gliding surface and a rider support surface;    a height measured between the gliding and rider support surfaces;    at one reinforcement extending along the board at a predetermined height-wise position;    from the first end to the second end, the board having a first end zone, a central zone, and a second end zone;    in the central zone, at least one of the at least one reinforcement having at least a portion with structure mechanically weaned structure with respect to a structure of a remainder of the reinforcement.    
     
     
         2 . A board according to  claim 1 , wherein: 
 the central zone successively has a first retention zone, a second intermediary zone, and a second retention zone;    the portion having a mechanically weakened structure is positioned in the second intermediary zone.    
     
     
         3 . A board according to  claim 1 , wherein; 
 the portion having a mechanically weakened structure comprises a mechanical weakening made by a reduction in quantity of material within the reinforcement.    
     
     
         4 . A board according to  claim 1 , wherein: 
 the reinforcement has at least one groove, each of the at least groove having a substantially liner form and being substantially oriented along the longitudinal direction of the board.    
     
     
         5 . A board according to  claim 4 , wherein; 
 a fitting demarcates an inside of a groove, the fitting extending opposite the reinforcement and the core.    
     
     
         6 . A board according to  claim 4 , wherein: 
 the core has a housing for a fitting, the fitting extending only along the core in order to form a bottom of a groove of the reinforcement by being flush with the reinforcement on the side of the core.    
     
     
         7 . A board according to  claim 4 , wherein; 
 a groove of the reinforcement is plugged by a fitting.    
     
     
         8 . A board according to  claim 1 , wherein: 
 the reinforcement has at least one groove, the groove reducing the thickness of the reinforcement in the area in which the reinforcement extends.    
     
     
         9 . A board according to  claim 8 , wherein: 
 the groove is oriented substantially longitudinally with respect to the board.    
     
     
         10 . A board according to  claim 8 , wherein 
 the groove has a rounded form.
