Ski with brake

Abstract

A brake plate is swingably carried on the base of a snow ski for automatic deployment upon initial rearward movement of the ski. A pivot pin permits arcuate movement of the brake plate, between limit stops, about an axis transversely disposed of the ski. The pivot pin is recessed in the bottom of the ski. A base plate also may be inset into the base of the ski.

We claim:  
     
         1 - A brake for a snow ski having a bottom surface and a forward end and a rearward end, said brake comprising, 
 a base for installation on the bottom of the ski,    a brake plate,    a pivot coupling said brake plate to said base,    a first limit stop stopping travel of the plate in a position so as to depend from the pivot to inhibit rearward travel of the ski, and    a second limit stop limiting retraction of the brake plate toward the ski bottom during forward travel of the ski.    
     
     
         2 - A brake for a snow ski comprising, 
 a base for installation on the ski,    a brake plate,    a pivot coupling said brake plate to said base,    first and second limit stops limiting the brake plate to movement between a downwardly deployed position for braking of the ski and an upwardly retracted position allowing forward travel of the ski.    
     
     
         3 - The brake claimed in  claim 1  wherein said first limit stop is a surface area on the base.  
     
     
         4 - The brake claimed in  claim 3  wherein said second limit stop is inclined relative a horizontal plane containing the pivot.  
     
     
         5 - The brake claimed in  claim 1  wherein said brake plate at all times projects below the bottom surface of the ski.  
     
     
         6 - A snow ski including, 
 a bottom surface defining a recessed area,    a base for installation on the bottom of the ski,    a brake plate having a segment disposed below the bottom of the ski,    a pivot coupling said brake plate to said base,    a first limit stop stopping forward travel of the brake plate in a position so as to depend from the pivot to inhibit rearward travel of the ski, and    a second limit stop limiting rearward retraction of the brake plate toward the ski bottom during forward travel of the ski.    
     
     
         7 - A snow ski including, 
 a brake plate,    a pivot carried by the ski,    said brake plate swingably carried by said pivot, and    at least one surface area on said ski limiting brake plate travel about said pivot.    
     
     
         8 - A snow ski comprising, 
 top and bottom surfaces the latter defining a recess    a brake including a brake plate inhibiting rearward travel of the ski,    a pivot in said recess and on which said brake is carried,    means for attaching said pivot to the snow ski, and    limit stops for limiting brake plate movement between a deployed braking position and a retracted trailing position during forward travel of the ski.    
     
     
         9 - The snow ski claimed in  claim 8  wherein one of said limit stops is a surface of the ski.  
     
     
         10 - The snow ski claimed in  claim 9  wherein said means for attaching said pivot to the snow ski includes a base plate.  
     
     
         11 - The snow ski claimed in  claim 8  wherein one of said limit stops limits travel of the brake plate to the trailing position whereat a segment of the brake plate projects below the bottom surface of the ski.
