Snow riding implement sidewall

Abstract

A snow riding implement includes a top face, a bottom face, a tail portion, a tip portion, and a midportion. A core of a first material extends from the tail portion to the tip portion. A sidewall extends between the top face and the bottom face and is formed from a second material different than the first material. The sidewall has a first side portion, a second portion and a third portion. The first side portion extends along the midportion at a first angle oblique to the bottom face, wherein the first side undercuts core. The second side portion extends along the tail portion at a second angle, different than the first angle, relative to the bottom face. The third side portion extends along the tip portion at a third angle different than the first angle relative to the bottom face.

What is claimed is: 
     
         1 . A snow riding implement comprising:
 a top face;   a bottom face;   a tail portion terminating at a tail end;   a tip portion terminating at a tip end;   a midportion between the tail portion and the tip portion;   a core of a first material extending from the tail portion to the tip portion; and   a sidewall extending between the top face and the bottom face, the sidewall being formed from a second material different than the first material, the sidewall comprising:
 a first side portion extending along the midportion at a first angle oblique to the bottom face, wherein the first side portion faces in an upward direction opposite to and facing the core; 
 a second side portion extending along the tail portion at a second angle, different than the first angle, relative to the bottom face; and 
 a third side portion extending along the tip portion at a third angle different than the first angle relative to the bottom face. 
   
     
     
         2 . The snow riding implement of  claim 1 , wherein the second angle is perpendicular to the bottom face. 
     
     
         3 . The snow riding implement of  claim 2 , wherein the third angle is perpendicular to the bottom face. 
     
     
         4 . The snow riding implement of  claim 1 , wherein the core is formed of a material selected from the group consisting of wood, a polyurethane foam and combinations thereof. 
     
     
         5 . The snow riding implement of  claim 1  further comprising a binding platform formed on the midportion. 
     
     
         6 . The snow riding implement of  claim 5 , wherein the core comprises a recess receiving the binding platform. 
     
     
         7 . The snow riding implement of  claim 1  further comprising an edge strip coupled to the bottom of the sidewall. 
     
     
         8 . The snow riding implement of  claim 7 , wherein the edge strip comprises a metal. 
     
     
         9 . The snow riding implement of  claim 7 , where in the sidewall comprises a polymer. 
     
     
         10 . The snow riding implement of  claim 8  further comprising a top sheet extending over the core and over a top of the sidewall. 
     
     
         11 . The snow riding implement of  claim 10  further comprising a base below the core alongside the edge strip. 
     
     
         12 . The snow riding implement of  claim 1 , wherein the first angle is no greater than 80 degrees. 
     
     
         13 . The snow riding implement of  claim 1 , wherein the first angle is no greater than 70 degrees. 
     
     
         14 . The snow riding implement of  claim 1 , wherein the first angle is no greater than 60 degrees. 
     
     
         15 . The snow riding implement of  claim 1  further comprising:
 a second sidewall extending between the top face and the bottom face, opposite the first sidewall, the second sidewall being formed from the second material, the second sidewall comprising: 
 a fourth side portion extending along the midportion at a fourth angle oblique to the bottom face, wherein the fourth side portion faces in an upward direction opposite to and facing the core; 
 a fifth side portion extending along the tail portion at a fifth angle, different than the fourth angle, relative to the bottom face; and 
 a sixth side portion extending along the tip portion at a sixth angle different than the fourth angle relative to the bottom face. 
 
     
     
         16 . The snow riding implement of  claim 1 , wherein the snow riding implement comprises a snowboard. 
     
     
         17 . The snow riding implement of  claim 1 , wherein the snow riding implement comprises a snow ski. 
     
     
         18 . The snow riding implement of  claim 1 , wherein the first side portion of the sidewall has a first vertical height and wherein the second side portion of the sidewall has a second vertical height less than the first vertical height. 
     
     
         19 . The snow riding implement of  claim 18 , wherein the second side portion slopes downwardly towards the tail end. 
     
     
         20 . The snow riding implement of  claim 1 , wherein the first side portion has a horizontal width that tapers towards the tail end. 
     
     
         21 . The snow riding implement of  claim 1 , wherein the first side portion of the sidewall has a first vertical height and wherein the third side portion of the sidewall has a second vertical height less than the first vertical height.
