Abstract

A shaft with a reinforcing core is provided for use in a hockey stick that improves the stiffness to weight ratio and durability of the shaft compared to a traditional wood shaft yet costs substantially less than an all composite shaft.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A shaft-like apparatus for playing sports comprising: 
 an outer portion formed of a first material; and    a core portion formed of a second material disposed within said outer portion wherein said core portion is at least one of stiffer and lighter than a material removed from said outer portion to accommodate said core portion.    
     
     
         2 . The apparatus according to  claim 1  wherein said outer portion comprises wood.  
     
     
         3 . The apparatus according to  claim 2  further comprising a plurality of side portions disposed adjacent to said outer portion.  
     
     
         4 . The apparatus according to  claim 3  wherein said plurality of side portions comprise composite laminates.  
     
     
         5 . The apparatus according to  claim 1  wherein said outer portion includes a first section secured to a second section along a longitudinal axis.  
     
     
         6 . The apparatus according to  claim 5  wherein said first section and said second section are secured along a major axis of said outer portion.  
     
     
         7 . The apparatus according to  claim 1  wherein said core portion comprises a composite material.  
     
     
         8 . The apparatus according to  claim 7  wherein said composite material comprises graphite composite.  
     
     
         9 . The apparatus according to  claim 1  wherein said core portion comprises metal.  
     
     
         10 . The apparatus according to  claim 1  wherein said core portion comprises a hollow tube.  
     
     
         11 . The apparatus according to  claim 10  wherein said hollow tube comprises metal.  
     
     
         12 . The apparatus according to  claim 1  wherein said core portion has an elliptical cross-sectional configuration.  
     
     
         13 . The apparatus according to  claim 1  wherein said core portion further comprises a plurality of core elements distributed within said outer portion.  
     
     
         14 . The apparatus according to  claim 1  wherein said core portion has a rectangular cross-sectional configuration.  
     
     
         15 . The apparatus according to  claim 1  wherein said core portion has an I-shaped cross-sectional configuration.  
     
     
         16 . The apparatus according to  claim 1  wherein said core portion has transverse bores formed therethrough.  
     
     
         17 . A shaft-like apparatus for playing sports comprising: 
 an outer portion formed of a first material; and    an elliptical core portion formed of a second material axially disposed within said outer portion.    
     
     
         18 . The apparatus according to  claim 17  wherein said outer portion comprises wood.  
     
     
         19 . The apparatus according to  claim 17  further comprising a plurality of side portions disposed adjacent to said outer portion.  
     
     
         20 . The apparatus according to  claim 19  wherein said plurality of side portions comprise composite laminates.  
     
     
         21 . The apparatus according to  claim 17  wherein said core portion comprises composite.  
     
     
         22 . The apparatus according to  claim 17  wherein said outer portion comprises two sections.  
     
     
         23 . The apparatus according to  claim 17  wherein said core portion is hollow.  
     
     
         24 . A hockey stick comprising: 
 a blade; and    a shaft coupled to said blade;    wherein said shaft of said hockey stick includes a wooden outer portion and a composite core portion.    
     
     
         25 . The apparatus according to  claim 24  further comprising a plurality of side portions disposed adjacent to said outer portion.  
     
     
         26 . The apparatus according to  claim 25  wherein said plurality of side portions comprise composite laminates.  
     
     
         27 . The hockey stick according to  claim 24  wherein said outer portion includes a first section secured to a second section along a longitudinal axis of said shaft.  
     
     
         28 . The hockey stick according to  claim 27  wherein said first section and said second section are secured along a major axis of said shaft.  
     
     
         29 . The hockey stick according to  claim 24  wherein said core portion has a substantially ellipsoidal configuration.  
     
     
         30 . The hockey stick according to  claim 29  wherein said core portion is hollow.
