  • Patent number: 4274639
    Abstract: An exercise and game apparatus in which a ball having shafts attached thereto is rotatably mounted by the shafts within a hoop. Two attachment bars extend diametrically outwardly from the hoop and are secured to devices on belts around two people using the apparatus. Handles on the bars are provided to assist in steadying the apparatus as a revolving movement of the person's hips causes the ball to spin within the annular ring. Baskets may be provided on the attachment bars so that the people using the device can throw a ball back and forth, attempting to throw the ball into the basket on the opposite side of the hoop while continuing the hip movement necessary to keep the ball spinning.
