Device for sliding on snow

Abstract

Device for sliding on snow, especially a carving ski, having a base running face, which extends over a front, a central and a rear zone and which is waisted in the longitudinal direction, wherein in the front and/or in the rear zone of the base running face, the latter is overlaid by at least one additional running-face segment which, together with a portion, especially the central portion, of the base running face defines a second running face having a second waist with a substantially larger radius of curvature.

1 . A carving ski or other device for sliding on snow, said device comprising: 
 a front zone,    a central zone,    a rear zone, and    a base running face, said base running face extending over said front, central and rear zones, and said running face being waisted in the longitudinal direction, wherein in the front and/or in the rear zone of said base running face, said base running face is overlaid by at least one additional running-face segment which, together with the central or another portion of the base running face defines a second running face having a second waist with a substantially larger radius of curvature.    
     
     
         2 . A device for sliding on snow according to  claim 1 , wherein the base running face and the running-face segments overlying it to the front and/or to the rear, are so matched with one another that, as the edging angle of the device for sliding on snow is changed, a corresponding change occurs in the active, that is effective, radius of the waist defined by the base running face and overlying running-face segment(s).  
     
     
         3 . A device for sliding on snow according to  claim 2 , wherein said device is so constructed and arranged that as the edging angle increases, the active radius becomes correspondingly increasingly smaller.  
     
     
         4 . A device for sliding on snow according to  claim 2 , wherein the active radius is a maximum at a first edging angle of approximately 0° and a minimum at a second edging angle.  
     
     
         5 . A device according to  claim 4 , wherein said second edging angle is an angle selected from the group consisting of at least 8°, from 8° to 12°, and 10°.  
     
     
         6 . A device for sliding on snow according to  claim 1 , wherein the waist of the base running face and/or the second waist is/are formed substantially from one or more circular arcs constructionally matched with respect to one another.  
     
     
         7 . A device for sliding on snow according to  claim 1 , wherein the radius of curvature of the waist of the base running face and/or of the second waist decreases from the front zone and/or from the rear zone to the central zone.  
     
     
         8 . A device for sliding on snow according to  claim 1 , wherein the second waist has a substantially constant radius of curvature over the front zone and/or the rear zone with respect to the central zone.  
     
     
         9 . A device for sliding on snow according to  claim 1 , wherein the base running face and the running-face segment(s) overlying it are bounded laterally by steel edges or like edges and define a corresponding “sidecut”.  
     
     
         10 . A device for sliding on snow according to  claim 1 , wherein said overlying running-face segment(s) is/are fastened to the running-face side of the device for sliding on snow in such a manner as to be detachable.  
     
     
         11 . A device according to  claim 10 , wherein said overlying running-face segment(s) is/are fastened to the running-face side of the device for sliding on snow by means of fastening screws that are operable from the top side of the device.  
     
     
         12 . A device for sliding on snow according to  claim 1 , wherein the front and/or the rear overlying running-face segments each extend outwards from the base running layer rising increasingly, in a direction towards the front or towards the rear, respectively, beyond the base running face.  
     
     
         13 . A device for sliding on snow according to  claim 1 , wherein said overlying running-face segment(s) are fastened to the device with resilient elements interposed.  
     
     
         14 . A device according to  claim 13 , wherein said overlying running-face segment(s) are fastened to the device through an interposed elastomeric layer.  
     
     
         15 . A device according to  claim 14 , wherein said interposed elastomeric layer has a shock-absorbing action.
