  • Patent number: 7377856
    Abstract: A playground apparatus comprising at least three separate elongated plank extending in a generally horizontally spaced end-to-end relationship, at least one pivotal support member for pivotally supporting each of the elongated plank in vertically spaced relationship above a support surface for vertical pivotal movement of opposite ends of the elongated planks, and at least two resiliently flexible living hinges each providing a void-free connection between adjacent ends of the elongated planks to eliminate a pinch point while providing for simultaneous vertical movement of said elongated planks.

  • Patent number: 5364313
    Abstract: A child's amusement device having a torsible beam with the torsible beam having a child-support surface for a child to sit or stand on with pivotal supports spaced about and supporting the periphery of the torsible beam, with the torsible beam having sufficient rigidity to remain in a fixed position when no external force is applied to the child-support surface, and the torsible beam having sufficient resiliency so that when an external force deflects the torsible beam, the torsible beam flexes and twists in response thereto, causing the torsible beam to oscillate about the pivotal supports and thereby provide an amusement ride for a child thereon.
