Abstract:
1. A compact collapsible stroller comprising a mobile base and a juvenile seat coupled to the mobile base, wherein the mobile base includes a cart and a gear-driven foldable frame mounted for folding and unfolding movement on the cart and configured to include a cart pusher and a rolling cart stabilizer, the rolling cart stabilizer is mounted on the cart for pivotable movement about a front pivot axis between an unfolded front position extending in a forward direction away from the cart and a folded rear position alongside the cart, the cart pusher is mounted on the cart for pivotable movement about a rear pivot axis between an unfolded rear position extending in an opposite rearward direction away from the cart and a folded rear position alongside the cart, the rolling cart stabilizer includes a rotatable driven gear, and the cart pusher includes a rotatable drive gear mated to the rotatable driven gear to provide means for rotating the driven gear to move the rolling cart stabilizer relative to the cart about the front pivot axis from the unfolded front position to the folded front position in response to rotation of the drive gear caused by movement of the cart pusher relative to the cart about the rear pivot axis from the unfolded rear position to the folded rear position so that the stroller is converted from an expanded use mode to a compact collapsed storage mode wherein the rolling cart stabilizer further includes a rotatable front gear axle coupled to the cart for rotation about the front pivot axis, a wheel mount coupled to the rotatable front gear axle and arranged to pivot about the front pivot axis in response to rotation of the front gear axle about the front pivot axis, and a front wheel coupled to the wheel mount, and wherein the rotatable front gear axle is coupled to the rotatable driven gear to rotate therewith in response to rotation of the rotatable drive gear during folding and unfolding of the gear-driven foldable frame.
