摘要： A collapsible frame structure for a playard. The collapsible frame structure includes a plurality of legs, and a plurality of cross members arranged so that at least one cross member extends between, and is pivotally connected to, respective adjacent legs to form a side of the playard. The frame structure also includes a plurality of slider joints, each slider joint slidingly engaging a respective one of the legs, and a plurality of pivot joints, each pivot joint on a respective one of the legs. The frame structure also includes at least one latch mechanism configured to selectively engage at least one of the slider joints with its respective leg, wherein each cross member is mounted to the respective adjacent legs by the slider joint on a first of the respective adjacent legs and by the pivot joint on a second of the respective adjacent legs.
