摘要： A pair of stuffed or, preferably, inflated bags or balls are suspended by respective elastic cords or strips from a support, such as a slotted buckle, permitting selective adjustment of the length of the strips. The buckles are attached by universal-type, swivel connectors to opposite ends of a U-shaped arm which is supported at its center from a fixed, overhead support by connecting means which also permit universal, swiveling motion of the arm, which may also be pivoted about a vertical axis with respect to the connecting means. The balls may be struck by the hands or feet, depending upon the height of adjustment, of one or more individuals utilizing the apparatus either solely for exercise or amusement, or as a game with specified rules or patterns.
