Sports board with adjustably flexible stringer

Abstract

An adjustably flexible stringer and a sports board employing the stringer are disclosed. The sports board includes a foam core in which the stringer is embedded. The stringer includes a plurality of flexible longitudinal strips overlapped with one another and is arranged from one end to the other end in order of increasing flexibility. Specifically, the strips vary in length from each other. Alternatively, the strips may vary in height, width or materials. By varying the arrangement of the strips, an almost unlimited number of configurations may be attained. As such, the sports board employing that stringer may be constructed in a variety of maulers with desired flexibility.

1 . A sports board comprising:
 a foam core having a front end and a rear end; said front end facing in a forward direction of said sports board; and   a stringer arranged within said foam core, extending substantially from said front end toward said rear end of said foam core, and including a plurality of flexible longitudinal strips overlapped with one another.   
   
   
       2 . The sports board of  claim 1 , wherein said stringer is arranged from one end to the other end in order of increasing flexibility. 
   
   
       3 . The sports board of  claim 2 , wherein said strips are arranged within said foam core top to bottom in order of increasing length. 
   
   
       4 . The sports board of  claim 3 , wherein said strips are vertically aligned at one end toward said rear end of said foam core. 
   
   
       5 . The sports board of  claim 3 , wherein said strips are arranged top to bottom in order of increasing flexibility. 
   
   
       6 . The sports board of  claim 4 , wherein said strips are arranged top to bottom in order of increasing flexibility. 
   
   
       7 . The sports board of  claim 5  further comprising a reinforcing bar arranged in said foam core and parallel with said stringer. 
   
   
       8 . The sports board of  claim 6  further comprising a reinforcing bar arranged in said foam core and parallel with said stringer. 
   
   
       9 . A stringer including a plurality of flexible longitudinal strips overlapped with one another, wherein said strips are arranged top to bottom in order of increasing length and are vertically aligned at one end. 
   
   
       10 . The sports board of  claim 9  wherein said strips are arranged top to bottom in order of increasing flexibility.
