Patent attributes
A collapsible frame structure, movable between an open arrangement and a folded arrangement, includes a plurality of legs, a plurality of cross members arranged in pairs, a plurality of slider joints and pivot joints, and at least one latch mechanism. Each pair of cross members is located between respective adjacent legs to form sides of the collapsible frame structure that define an interior of the collapsible frame structure. Each slider joint slidingly engages a respective one of the legs and pivotably attaches to two adjacent cross members. Each pivot joint is at a respective one of the legs to pivotably attach two adjacent cross members. The latch mechanism, which is mounted to another frame component of the collapsible frame structure, remains so mounted in both the open arrangement and the folded arrangement. Nonadjacent legs and nonadjacent sides of the collapsible frame structure remain unconnected across an interior of the collapsible frame structure.
