Abstract:
An arm exercising device for strengthening a user's bicep and tricep muscles, said exercising device comprising:an upper arm support platform attachable to a user's upper arm adjacent a user's tricep muscle under a user's upper arm, said upper arm support platform having a pivot end and a remote end and an arm support area therebetween;means for holding said upper arm support platform against a user's upper arm;a hand driven assembly having a platform-attaching end and a hand grasping end, said hand driven assembly being pivotally attached at a pivot hinge at its platform-attaching end to the pivot end of said upper arm support platform;a handle attached to said hand driven assembly at said hand grasping end said handle being held to said hand driven assembly so that while the handle is moved toward and away from the remote end of the upper arm support platform by a user grasping, actively exerting force, and moving the handle by exertion of the user's bicep and tricep muscles whilst the upper arm support platform is attached to a user's upper arm during exercise, the handle will move in an axial direction along the hand driven assembly closer to and further away from the pivot end;means for adjustably applying frictional resistance at said pivot hinge to absorb the force exerted by the user by the exertion of the user's bicep and tricep muscles during the pivoting back and the pivoting forth between the upper arm support platform and the hand driven assembly to actively exercise the user's bicep and tricep muscles and wherein said hand driven assembly comprises:a pair of cylinder assemblies each cylinder assembly having a hinged end attached to said pivot hinge and a piston rod support end;a pair of piston rods, each piston rod having a piston end slidably held in one of said pair of cylinder assemblies and extending out of the piston rod support end and each piston rod terminating in a handle end; andsaid handle is held between said handle end of each of said pair of piston rods and while the handle is moved toward and away from the remote end of the upper arm support platform by a user, the pair of piston rods slide in and out along each cylinder assembly.
