  • Elevated hand-held merry-go-round
    Patent number: 8529362
    Abstract: An elevated hand held merry go round provides a hand hold elevated a distance above a playing surface to which a user may grab and rotate through an unobstructed zone between the hand hold and the playing surface. In the preferred embodiment the hand hold may be tilted at an angle relative to the playing surface so the user may pump themselves to maintain the round momentum in a manner somewhat similar to an individual pumping themselves on a swing to maintain themselves swinging. Alternative embodiments lack the tilt may be made in various dimensions to accommodate various numbers of users and may have more than one set of locations for hand holds.
