发明名称 Amusement devices
摘要 An amusement device is shown which comprises a lightweight bag tethered at its opposite ends to upper and lower, pivotal swivels. The bag is suspended by the upper cord and the lower cord has a length substantially greater than the normal distance of the bag from the lower swivel. The bag is readily deformable and resilient so that it cannot cause injury. The cords are elastic and resilient so that when it is struck by a players hand, or fist, it gyrates and travels in an unpredictable fashion presenting a challenge to its being repetitively hit, as is the object of its competitive use where players attempt to cause the bag to strike an opponent. The device is uniquely adapted for use by persons confined in wheel chairs.
