Playard with compact folded configuration and storage latch

Abstract

A frame for a foldable playard includes multiple leg support assemblies and X-frame assemblies that provide and maintain clearances in accordance with consumer safety standards when the playard is fully folded, fully unfolded, or between the folded and unfolded configurations. These assemblies further facilitate a compact size in the folded configuration. Each leg support assembly includes a leg tube, a corner, and a slider where the corners and the sliders have arms rotatably coupled to the X-frame assemblies. For each pair of adjacent leg support assemblies, the respective arms of the sliders and the corners are dimensioned to provide the desired clearances while being offset such that the respective arms of the sliders and the corners overlap one another when the frame is folded, thus facilitating a compact size of the folded frame. The frame may also include a storage latch to lock the frame in the folded configuration.
