Device for fixing the boot attachment base to a snowboard

Abstract

A device for fixing a boot attachment base to a snowboard, the device including a base with a seat housing a first disc, the disc and seat having cooperating teeth. The first disc includes a rim defined about its upper surface, multi-lobed holes or apertures, and a centrally located slotted hole extend through the first disc. A second, smaller disc fits within the rim on the first disc, the second disc includes a centrally located slotted hole and multi-lobed holes. The slotted holes in the discs are disposed perpendicular to one another, the multi-lobed holes are aligned, and a locking assembly, including a parallelepiped block, fits within the holes and engages them simultaneously. A square nut, screw, and washer, complete the locking assembly for the pair of discs.

We claim:  
     
         1 . A device for fixing the boot attachment base to a snowboard comprising: 
 a base provided with a seat, the edge of which is provided with a plurality of teeth, said seat housing a first disc provided on its lower surface with a plurality of teeth cooperating with the teeth on the edge of said seat;    a second disc superposed on said first disc, said first and second discs being provided with slotted holes disposed mutually perpendicular and engagable by a member slidable within said slotted holes, said first and second discs being rotatively locked relative to said member; and    fixing means passing through said first and second discs to secure said base to the snowboard.    
     
     
         2 . A device as claimed in  claim 1 , characterized in the first disc has a greater diameter than the second disc.  
     
     
         3 . A device as claimed in  claim 2  wherein an annular rim is defined on the upper surface of said first disc and said second disc fits within said rim.  
     
     
         4 . A device as claimed in  claim 1 , characterized in that said member is of parallelepiped shape.  
     
     
         5 . A device as claimed in  claim 1 , characterized in that surface of the first disc which faces the second disc is provided with friction-generating ribs.  
     
     
         6 . A device as claimed in  claim 1  wherein said slotted hole in said first disc is located in the center of said first disc, and said slotted hole in said second disc is located in the center of said second disc.  
     
     
         7 . A device for fixing the boot attachment base to a snowboard comprising: 
 a base provided with a seat, the edge of which is provided with a plurality of teeth, said seat housing a first disc provided on its lower surface with a plurality of teeth cooperating with the teeth on the edge of said seat,    the invention being characterized by: 
 a second disk superposed on said first disc, said first and second discs being provided with slotted holes disposed mutually perpendicular and engagable by a member slidable within said slotted holes, said first and second discs being rotatively locked relative to said member; and  
 fixing means passing through said first and second discs to secure said base to the snowboard.
