发明名称 Dangling play ball or swing - is fixed by rope of adjustable length to hook in ceiling
摘要 <p>The play ball is similar in size to a football and is fixed by means of loops (1a, 2a) to a rope (2). The length of this rope is adjustable by an adjusting ring (3) in the form of a double loop, one loop being fixed to the free end of the rope, the other forming an adjusting slide on the rope, to raise or lower the height of the ball from the floor whilst the looped rope is held in a hook (x) in the ceiling so that the ball can be hit by any part of the head, body or legs, or used as a swing.</p>
