ABSTRACT:
The arm wrestling device is for providing a clockwise and counterclockwise rotational resistance force in opposition to the rotation of an individual user's forearm about its respective, stationary elbow joint. The device includes a base structure for supporting the user's rotational forces and the remaining elements of the device. These elements include an elbow placement and receiving means, a rigid lever arm and a clockwise and counterclockwise rotational force resistance means. The rigid lever arm has an upper portion for hand gripping by the user and a lower portion having a generally horizontal axis of rotation. At rest, the lever arm extends in a generally vertical direction in proximity to the elbow placement means so that the user can comfortably grasp the upper portion of the lever arm. Subsequent to elbow placement and hand grasping the user rotates the lever arm in either rotational direction, depending upon left or right handed predisposition, and encounters the resistance force which is communicatively connected to the axis of rotation of the lever arm. The device is equipped with adjustable elbow placement means to effectuate device use for athletic or therapeutic purposes to users irrespective of arm length. The device is also equipped with rotatable gripping handle at the upper portion of the lever arm, adjustable resistance force means, force readout means, and a pair of hand gripping posts to closely assimilate the sport of arm wrestling.
