Abstract
A compact collapsible stroller includes a main stroller frame. The main stroller frame includes a central frame hub, and a handle portion, a rear leg portion and a front leg portion that can separately be pivotally coupled to the central frame hub. The main stroller frame further includes an adapter portion attached to the handle portion. The stroller has an unfolded state for use and a folded state for storage. When the stroller changes from the unfolded state to the folded state, the adapter portion approaches a rear wheel set. The main stroller frame can be compactly folded using a series of pivot points, which may accept child seats of various configurations during installation. The seat can be folded in a manner suitable to the folding boundary size of the main stroller frame, thereby keeping the folding size of the stroller unit minimal.
