摘要:
Embodiments of the present disclosure are directed to a rotatable play device that comprises a central support post, a hub rotatably mounted to an upper end of the central support post, and an arm assembly attached to the hub and comprising a plurality of arms, a seat being suspended from the distal end of each of the plurality of arms. Rotation of the hub about the central support post causes the plurality of seats to rotate around the central support post in a substantially circular rotation path. Each of the seats may also be configured to move up and down by way of a spring assembly or a plurality of springs. Two or more seats may share the up-and-down movement in an alternating manner or each seat may be configured to have an independent up-and-down movement. In addition, each of the seats may optionally be configured to swing in substantial alignment with the circular rotation path and/or to swing outward due to centripetal forces created by the circular rotation path.
