  • Patent number: 7618301
    Abstract: Playsets having pop-up structures. Pop-up structures may be adapted to transition to an erect configuration when the playset is in an open configuration, in which at least a portion of the pop-up structure may extend outside of a perimeter of the playset, and to a compact stowed configuration when the playset is in a closed configuration, in which the pop-up structure is disposed within the perimeter. Playsets may include elements adapted to urge a portion of the pop-up structure toward the erect configuration or one or more playset-accessory retention chambers. Some examples may include first and second latch elements that are adapted to cooperatively retain the playset in the open configuration. Other examples may include a fastener adapted to be moved selectively between a clasping position in which the fastener retains the playset in the closed configuration and a linking position in which the fastener couples to a second playset.
