Strength training amusement device for simulating arm-wrestling










Image Number 10 for United States Patent #4805900.

An upright mechanical arm is pivoted to a freestanding base for grasping by a player to simulate an arm-wrestling contest. The arm is power-driven in a given direction by a hydraulic jack. The force applied by the jack is adjustable. Switches detect grasping of the mechanical arm by the player and positioning of the player's elbow on an elbow pad. Such switches are interconnected with control of the hydraulic jack to cut off the supply of hydraulic liquid automatically. Bells and buzzers can be provided to indicate when the game has been "won" or "lost" by the player.
