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.
