摘要：An electrically operated rebound adjuster for a punching bag, comprising a reversible electric drive motor which rotates a vertically mounted screw threaded spindle or shaft on the lower end of which a punching bag is supported so as to lectively rai or lower the position of the punching bag relative to a horizontal rebound board. Limit controls prevent excessive travel of the shaft in either direction to prevent excessive raising or lowering of the punching bag relative to the rebound board. The rebound board supports the entire control asmbly through supporting brackets.
