ABSTRACT:
A reactive means for a punching bag comprising a shaft for mounting the bag, a resinous resilient bearing and housing through which the shaft passes and in which the shaft pivots, an adjustable pressure plate for imparting a damping effect upon the motion of the bag by compressing the resinous bearing, and a supporting structure. Also disclosed are optional attachments of reactive and motivative devices to the shaft such as springs, weights, and fluid activated cylinders. The effect of the resinous bearing, and the reactive and motivative means attached to the shaft, is to cause the movement of the bag to mimic that of a human opponent.
