Boxing exercise apparatus with damping adjustment
First Claim
1. A boxing exercise apparatus comprising:
- a stand providing a base for supporting the apparatus;
a support arm means having a distal end and a proximal end, the distal end being hingably engaged with the stand enabling the support arm means to move between a rocked-back position and a rocked forward position, a neutral position thereof dividing the rocked-back and the rocked-forward positions;
a strike absorbing means attached at the proximal end of the support arm means and movable therewith;
a primary biasing means comprising a primary energy storing means joined end-to-end with a rigid rod means, the primary biasing means being pivotally engaged at one end thereof with the stand and at the other end thereof with the support arm means so as to urge the support arm toward the neutral position, the primary energy storing means biasing the rigid rod means to move in contact along a sliding surface of the stand when the support arm means is moved into the rocked-back position, said movement of the rigid rod means being retarded by the primary energy storing means.

Abstract
A boxing exercise apparatus is mounted on a stand. A pivoted support arm provides a strike absorbing means. In a first embodiment, the support arm is connected to the stand with a spring joined to a rigid rod. The rigid rod is preferably positioned in a neutral position with an integral positioning means. Displacement of the support arm away from the neutral position toward a rocked-back position is counteracted by the spring. In a second embodiment, the apparatus further includes a second spring joining segments of the stand so as to bias lateral movement of the support arm. When the support arm is deflected, the first spring and the second spring retards the motion of the support arm within two degrees of freedom. A friction adjustment is provided so as to adjust motion stiffness. This adjustment provides a novel approach using a friction washer.
