The present disclosure relates to a juvenile playyard, and particularly to a collapsible frame for a juvenile playyard. More particularly, the present disclosure relates to a collapsible playyard frame including top rail segments that fold up when the playyard frame is collapsed.
A playyard in accordance with the present disclosure includes a collapsible frame. The collapsible frame includes a multi-segment top rail and a rail support coupled to the top rail and adapted to support a playyard floor.
In illustrative embodiments, a playyard top rail includes a left rail segment and a right rail segment. Both the left rail segment and the right rail segment are coupled to a bracket for pivotable movement relative to the bracket. The rail segments move relative to the bracket from an inline-use position to a folded-storage position when a playyard including the playyard top rail is collapsed for storage or transportation.
In illustrative embodiments, the playyard top rails further includes a rail segment lock associated with the left and right rail segments. The rail segment lock moves from a locked position, blocking the left and right rail segments from moving to the folded-storage position, to an unlocked position, allowing the left and right rail segments to move to the folded-storage position. The rail segment lock is moved to the unlocked position by a user lifting the bracket, pressing a blocker-mover button included in the rail segment lock, and dropping the bracket while continuing to press the blocker-mover button.
In illustrative embodiments, the playyard top rail also includes visual means for indicating the position of the rail segment lock so that a caregiver can quickly determine if the rail segment lock is in the locked or unlocked position. The visual means includes a locked indicator coupled to the rail segment lock and an unlocked indicator coupled to the bracket. The locked indicator is illustratively green in color. It is exposed when the rail segment lock is in the locked position. The unlocked indicator is illustratively red in color and is exposed when the rail segment lock is in the unlocked position.
Additional features of the disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
