A plastic article is recited having a plastic shell including walls defining a cavity. Within the cavity is an in-situ foam core including expanded polymer beads. A layer of the expanded polymer beads includes a layer of distorted beads adjacent to the walls. The in-situ foam core has a thermal bond to the walls.

An amusement ride requires the participant to ascend to a platform for the beginning of the amusement ride via a single or a double helix ladder. The participants are tethered for safety. Operators attend the tether lines. The moving climbing wall surmounts an upper roller and a lower roller. One of the rollers is connected to a power source for movement of the moving climbing wall around the rollers. A controller controls the power source.

The present disclosure provides a collapsible activity structure. The structure includes panels arranged in a chain-like structure through hinges. Each hinge is coupled to a first connecting end of a panel to a second connecting end of an adjacent panel of the plurality of panels. In a folded position of hinges, the panels are in a stacked configuration. A coupling member including a male coupling member and a female coupling member is provided. The male coupling member is disposed onto the first connecting end of a first end panel and the female coupling member is disposed onto the second connecting end of a second end panel of the chain-like structure. The male and the female coupling members are coupled to each other to lock the first and the second end panels in an unfolding position of the hinges to form a frustum configuration.

The present disclosure is directed to climbing units that provide an enhanced play experience through the incorporation of any of a variety of elements including nets, suspended portions, and coupling elements, and to playground structures that contain those climbing units. In some embodiments, the climber unit may comprise one or more rigid portions and one or more net-containing portions connected end-to-end to produce a continuous climbing pathway. In other embodiments, the climber unit may comprise one or more rigid portions and one or more suspended portions connected end-to-end to produce a continuous climbing pathway. The suspended portion may be attached to adjacent rigid portions by flexible couplers, such that the suspended portion will move when a child climbs through it. In other embodiments, the climber unit may be mounted to an elevated playground structure such that there are no footers connecting the climber unit to the ground.
