Title: Lower frame structure of a foldable playyard

Abstract: A lower frame structure of a foldable playyard comprises a hub which is operable to lock the lower frame structure at an erected state and to unlock the lower frame structure to allow it to collapse to a collapsed state; four hub legs, one end portion of each of the hub legs being pivotally coupled to the hub such that the hub legs is capable of pivotal in a longitudinal direction of the hub between a erected position and a collapsed position; and a first and a second auxiliary supporting units disposed between a first hub leg and a forth hub leg, and a second hub leg and a third hub leg respectively, each auxiliary supporting member comprising a first tube whose first end is pivotally coupled to a hub leg, a second tube whose first end is pivotally coupled to another hub leg, and an elbow joint member pivotally coupling a second end of the first tube and a second end of the second tube, whereby as the lower frame structure is extended to a erected state the hub legs and the first and second auxiliary supporting units form a substantially horizontal co-planar spread-out configuration, and as the lower frame structure is collapsed to a collapsed state the hub legs and the tubes of the auxiliary supporting units being substantially parallel with each other.
