Skiing device including two supplemental elements held together by a connecting structure

Abstract

A board ( 1 ) for sliding on snow such as a ski, a monoski or a snowboard, with vertical plane of general symmetry (P), comprising a principal part, known as body or base ( 2 ), having the shape of an elongated beam having its own thickness distribution, contour, width and stiffness, and can be of any type of structure, and which includes a central zone known as of the waist ( 7 ) extended towards the front by a front part ( 8 ) raised at its end to form a tip ( 6 ), and towards the rear by a rear part ( 9 ) terminating in a tail ( 6 ′), including at least two supplemental elements ( 10 ) extending towards the front at least on the front part, to extend the zone of the waist, said supplemental elements including two longitudinal side arms ( 10 a , 10 b ) disposed laterally relative to the plane “P”, said longitudinal side arms constituting at least a dynamic means for recall of the base, characterized in that the side arms are connected by a transverse connector ( 11 ) including a part independent of the side arms.

1 . A board for sliding on snow such as a ski, a monoski or a snowboard, with a vertical plane passing through the central axis of the ski, comprising: 
 a base having the form of an elongated beam having its own thickness distribution, contour, width and stiffness, and including a central zone extended forwards by a front part raised at its end to form a tip, and towards the rear by a rear part ending in a tail;    at least two supplemental elements extending towards the front and/or towards the rear, at least on the front part and/or rear part to extend the central zone, said supplemental elements including two longitudinal side arms disposed laterally relative to the central plane, said longitudinal side arms constituting at least a dynamic means of recall for the base, the side arms being connected by a transverse connector including a part independent of the side arms.    
     
     
         2 . The board for sliding on snow according to  claim 1 , wherein the transverse connector is attached to the side arms  
     
     
         3 . The board for sliding on snow according to  claim 1 , wherein it includes a position adjustment means for adjusting the longitudinal position of the transverse connector.  
     
     
         4 . The board for sliding on snow according to  claim 3 , further including a slide means for permitting longitudinal displacement of the transverse connector along the side arms.  
     
     
         5 . The board for sliding on snow according to  claim 4 , further including a means for indexing the longitudinal position of the transverse connector.  
     
     
         6 . The board for sliding on snow according to  claim 3 , further including a locking means for allowing the locking of the transverse connector relative to the side arms.  
     
     
         7 . The board for sliding on snow according to  claim 1 , wherein the front part of the base includes a longitudinal slit open to the front, said longitudinal slit separating the two side arms.  
     
     
         8 . The board for sliding on snow according to  claim 1 , wherein the two side arms are parallel.  
     
     
         9 . The board for sliding on snow according to  claim 1 , wherein the two side arms are convergent.  
     
     
         10 . The board for sliding on snow according to  claim 9 , wherein two side arms converge towards the front.  
     
     
         11 . The board for sliding on snow according to  claim 9 , wherein two side arms converge towards the central zone of the base.  
     
     
         12 . The board for sliding on snow according to  claim 1 , further including a platform attached to the base to support bindings for a boot.  
     
     
         13 . The board for sliding on snow according to  claim 12 , wherein the two side arms extend from the platform.  
     
     
         14 . A ski comprising: 
 an elongated body including a front part, a central zone, and a rear part;    a pair of side arms extending along and joined to the front part;    a cross piece independent from the side arms and being connected to the side arms.    
     
     
         15 . The ski according to  claim 14 , wherein the side arms form a pair of longitudinally extending profiles and the cross piece has grooves that receive the profiles.  
     
     
         16 . The ski according to  claim 15 , wherein the cross piece is slidably mounted on the profiles and further including indexing means for indexing to the cross piece to position the cross piece along the side arms.  
     
     
         17 . The ski according to  claim 15 , wherein the side arms are integrally molded with the body.
