Fully functional gripable apertured weightlifting device

Abstract

A polyurethane coated weighted core is provided which is adapted to receive and be lifted by a bar in the hand or hands of a user. The core which may be in configuration of a conventional weightlifting plate is provided with at least one aperture which when gripped by a user presents a gripable surface possessing sufficient friction to allow safe use.

1 . A polyurethane coated apertured weighted core comprising: 
 a core having a hole at its center disposed to receive a bar for lifting and supporting said core, at least one aperture located on the periphery of said core which is adapted to conform to a user's hand in order to allow lifting of the core, a polyurethane coating disposed over the entirety of said apertured core wherein the gripable interior surface of said polyurethane coated aperture is provided with a gripable surface which possesses sufficient friction to allow a user to safely lift the core.    
   
   
       2 . The polyurethane coated apertured weighted core as defined in  claim 1  wherein said core comprises a metal.  
   
   
       3 . The polyurethane coated apertured weighted core as defined in  claim 1  wherein said aperture comprises at least one slot.  
   
   
       4 . The polyurethane coated apertured weighted core as defined in  claim 1  wherein said apertured weighted core comprises a plate.  
   
   
       5 . The polyurethane coated apertured weighted core as defined in  claim 3  wherein said surface of said slot which comes into contact with a user's hand comprises lands and grooves.  
   
   
       6 . The plate as defined in  claim 1  wherein the polyurethane coating is applied by employing injection molding.  
   
   
       7 . The plate as defined in  claim 1  wherein the polyurethane coating is applied by employing cast molding.  
   
   
       8 . The plate as defined in  claim 1  wherein the polyurethane coating is applied by employing open pour molding.  
   
   
       9 . The plate as defined in  claim 1  wherein the polyurethane coating is applied by employing compression molding.  
   
   
       10 . The plate as defined in  claim 4  wherein the aperture in the plate comprises a slot and wherein said plate further comprises a slot in opposition to said slot.  
   
   
       11 . The plate as defined in  claim 1  wherein the area that provides the gripable surface comprises grooves.
