Abstract

Waterboards such as surfboards are described that are formed of a combination of a resilient foam core with an outer shell of polycarbonate or polyurethane. Such waterboards may further include fibrous material bonded to or embedded in the outer shell for additional strength.

Claims

exact text as granted — not AI-modified
1 . A buoyant waterboard, comprising
 an expanded, elastomeric plastic core;   and a plastic resin shell coating and adhered to said core.   
   
   
       2 . (canceled) 
   
   
       3 . The waterboard of  claim 1 , wherein said core comprises expanded polypropylene.

       13 . (canceled) 
   
   
       14 . (canceled) 
   
   
       15 . The waterboard of  claim 1 , wherein said core further comprises a fibrous material in the interior of said core. 
   
   
       16 . (canceled) 
   
   
       17 . The waterboard of  claim 1 , where in said shell coating further comprises a fibrous material. 
   
   
       18 . The waterboard of  claim 13 , wherein said fibrous material comprises glass fiber. 
   
   
       19 . The waterboard of  claim 13 , wherein said fibrous material comprises KEVLAR®. 
   
   
       20 . The waterboard of  claim 13 , wherein said fibrous material comprises polymide fiber. 
   
   
       21 . The waterboard of  claim 13 , wherein said fibrous material comprises polyurethane fiber. 
   
   
       22 . The waterboard of  claim 13 , wherein said fibrous material comprises carbon fiber. 
   
   
       23 . The waterboard of  claim 1 , further comprises a stringer. 
   
   
       24 . The waterboard of  claim 19 , wherein said stringer is perforated. 
   
   
       25 . (canceled) 
   
   
       26 . (canceled) 
   
   
       27 . (canceled) 
   
   
       28 . The waterboard of  claim 19 , wherein said stringer is a composite material stringer. 
   
   
       29 . (canceled) 
   
   
       30 . The waterboard of  claim 1 , wherein said shell coating is a polycarbonate. 
   
   
       31 . The waterboard of  claim 1 , wherein said shell coating is a polyurethane. 
   
   
       32 . The waterboard of  claim 1 , wherein said shell coating is a polyester. 
   
   
       33 . (canceled) 
   
   
       34 . The waterboard of  claim 1 , wherein said shell coating is a polyvinyl ester. 
   
   
       35 . (canceled) 
   
   
       36 . (canceled) 
   
   
       37 . (canceled) 
   
   
       38 . The waterboard of  claim 1 , wherein said waterboard is a surfboard. 
   
   
       39 . The waterboard of  claim 1 , wherein said waterboard is a sailboard. 
   
   
       40 . The waterboard of  claim 1 , wherein said waterboard is a body board. 
   
   
       41 . (canceled) 
   
   
       42 . (canceled) 
   
   
       43 . The method for making a buoyant waterboard, comprising
 forming a core in the desired shape of said waterboard from an expanded elastomeric plastic; and   applying and adhering to said core a coating substantially comprising a polycarbonate or polyurethane resin.   
   
   
       44 . The waterboard of  claim 1 , wherein
 said expanded elastomeric plastic core comprises expanded polypropylene, expanded polyethylene, or expanded SBS, and   said plastic resin shell comprises polyurethane and polycarbonate.
