Abstract: Embodiments of an arch-based play system are disclosed. The system incorporates an arch assembly or a group of arch assemblies. Play elements are connected to the arch assembly or assemblies. The system is modular in nature such that there are a wide variety of different possible implementation configurations. The wide variety of possible implementation configurations corresponds to a wide variety of different play experiences.

Abstract: An interactive activity system is disclosed. One embodiment includes a generator configured to produce electrical power based on physical interaction with a human being, a storage component configured to store the electrical power, and at least one play-oriented application configured to utilize a portion of the electrical power for operation. In one embodiment, the interactive activity system is implemented in a traditional, non-electronic playground environment.

Abstract: A climbing structure includes a first strut having an elongate portion, a first end portion and a transition portion between the elongate portion and the first end portion. The transition portion has a reduced thickness relative to the first end portion. A connection member has first and second connectable plates defining a first cavity. The first cavity is sized to receive and secure the first end portion therein.

Abstract: A device is disclosed for suspending a playground swing seat from an overhead support. The device comprises a length of stranded steel cable having a relatively small diameter with first and second connecting means at each end taking the form of an annular bushing with the cable looped around the bushing and secured by a ferrule. A swing handle formed from resilient material and having a diameter of about 1 inch is molded onto the lower end of the steel cable. The remaining length of the steel cable and both bushings are encapsulated by a molded resilient coating that has a diameter of about 5/16 inch.

Abstract: A playground apparatus is disclosed which includes four upright posts secured in the ground in a square configuration. Playground apparatus further includes four curved beam members formed from substantially rigid material, each of which is pivotally connected at its midpoint. The adjacent ends of the beams are interconnected by a resilient spring assembly, and the assembled beams define a ring-like support surface upon which children can stand and jump, producing undulating and resilient motion.
