Hand/Arm fulcrum and exercise device

Abstract

A hand/arm fulcrum acting exercise device made of two semi-cylindrical components whose lengths and diameter differ, with the smaller sized semi-cylinder optionally permanently or removably affixed to the larger component, the smaller diameter half cylinder acting to position the internal cavity of the palm of a user's hands. The larger semi-cylinder or base structure acts as a support base for the hand aligning member and further acts as the support base for the load-bearing structures of the anatomy of a user's hand.

What is claimed is: cm  1 ) A hand/arm fulcrum acting exercise device, so configured as to address the unique geometry of a user's hand comprised of a base and attached members comprising: 
 A) semi-cylindrical base structure with a hollow or opened bottom cavity for adding density; and  
 B) a second smaller semi-cylindrical structure permanently affixed or removably attached to said base structure having a distance between 1½″ to 2 inches in diameter and a length of not less than 2 inches to serve as a hand positioning member.  
 
   
   
       2 ) The hand/arm fulcrun exercise device as defined in claim  1 , wherein said base structure further comprises high friction pads or feet to restrict or prevent the movement of said base unit.  
   
   
       3 ) The hand/arm fulcrum exercise device as defined in claim  1 , wherein said smaller semi-cylindrical hand positioning member comprises an adjustable and removable strapping mechanism, having a tension adjustable means, which is attached via slots or cut-outs at either side of the hand location.  
   
   
       4 ) The hands/arm fulcrum exercise device as defined in claim  1 , wherein: 
 A) the base structure with the “opened-bottom” arrangement is equipped with two sets of straps that pass through slots running the lengthwise direction of the base structure, such that a weighted member may be added to said base structure, and then secured into place via said straps; and    B) the base structure having a closed bottom arrangement.    
   
   
       5 ) The hand/arm fulcrum acting exercise device as defined in claim  1 , wherein: said base structure having the open bottom configuration is equipped with key ways on either end of said hand positioning member, acting as passageways for cable, with loops at both ends, such that the cable and base structure can be attached to an external resistance mechanism.  
   
   
       6 ) The hand/arm fulcrum acting exercise device as defined in claim  1 , wherein said hand, distinct member is: 
 A) fixedly attached at a position, eccentric to the centerline of the bottom base structure component; and    B) removably attached to said base structure component, such that, it may be attached and removed and repositioned as desired via a series out of slot and tap configuration. With tabs fixedly attached to the hand positioning member and slots fixedly attached to said base member.    
   
   
       7 ) A body fulcrum device comprising: 
 C) semi-cylindrical base structure with a hollow or opened bottom cavity for adding density; and    D) a second smaller semi-cylindrical structure permanently affixed or removably attached to said base structure having a distance between 1½″ to 2 inches in diameter and a length of not less than 2 inches to serve as a hand positioning member.    
   
   
       8 ) The device of  claim 7  wherein said base structure further comprises high friction pads or feet to restrict or prevent the movement of said base unit.
