| Abstract: |
A punching bag simulator has a base for mounting on a stationary surface and a spring biased arm pivotly connected to the base and constrained to move only in a single plane with one end of the arm biased by the spring against a resilient bumper. On the other end of the arm a deformable pad is presented for striking by the fists and each time the pad is struck, the arm moves along a lineal path against the spring bias and snaps back to its original position for repeated striking. A pair of resilient bumper elements are placed between the pivoted arm and base in spaced relation to each other. One resilient element serves to absorb kinetic energy of the pivot arm when the pivot arm is moved towards the base against the spring bias and the other resilient element serves to absorb the kinetic energy of a pivot arm when the pivot arm is moved away from the base as a result of the spring bias.
