| 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.

First Claim:
Show all 5 claims |
What is claimed is:
1. A punching or speed bag simulator comprising a base member having provisions for mounting upon a stationary vertical surface, a pivot arm, means serving to pivotally interconnect said pivot arm to said base member, return spring means acting between said base member and said pivot arm and biasing said pivot arm in a rest condition so that a first end of said arm is disposed outwardly and away from said base, and a second end of said arm is disposed adjacent to said base, first bumper means interposed between said first end of said pivot arm and said base and being formed of a material and sized to absorb the excess kinetic energy imparted to said simulator in the punching action as the first end of the pivot arm approaches the limit of movement about the pivot axis, second bumper means interposed between said second end of the arm and said base member and being formed of a material serving to deaden the tendency of said pivot arm to bounce and rebound from the punching action, a punching bag element secured adjacent to said first end of said arm and being configurated to serve as a target for the human fists and being formed from a resilient material for deformation upon impact with the fists, the kinetic forces applied to said punching bag element by the fists serving to pivot said pivot arm against the bias of said return spring means about said pivot axis and towards said first bumper means, the forces developed in said spring means serving to snap back said pivot arm about said pivot axis so that said second end of said pivot arm engages said second bumper means in a substantially non-rebound action serving to position said punching bag element for a subsequent blow by the fists.
