1. A compact collapsible stroller comprising
a cart including a frame mount and at least one rear wheel mounted to rotate relative to the frame mount, a rolling cart stabilizer including a front wheel mount and at least one front wheel mounted to rotate relative to the front wheel mount, a first cam-fold unit including a base member coupled to the frame mount of the cart to move therewith, a follower coupled to the rolling cart stabilizer to move therewith, a motion-transfer pin arranged to extend into a pin-receiver slot formed in the base member and a motion-transfer slot formed in the follower, and a pin mover formed to include a motion-inducement slot receiving a portion of the motion-transfer pin therein, and a cart pusher coupled to the pin mover, wherein the motion-transfer pin is arranged to move in a first direction simultaneously in each of the pin-receiver, motion-transfer, and motion-inducement slots to engage the pin mover to simultaneously rotate the follower about a pivot axis in a counterclockwise direction and the cart pusher about the pivot axis in an opposite clockwise direction to cause the follower and the rolling cart stabilizer coupled to the follower to pivot about the pivot axis in a counterclockwise direction toward the cart to assume a folded front position alongside a front portion of the cart in response to movement of the cart pusher about the pivot axis in a clockwise direction toward an opposite rear portion of the cart so that the compact collapsible stroller is converted from an expanded use mode to a compact collapsed storage mode and to simultaneously rotate the follower about the pivot axis in the clockwise direction and the cart pusher about the pivot axis in the counterclockwise direction to cause the follower and the rolling cart stabilizer coupled to the follower to pivot about the pivot axis in a clockwise direction away from the cart to assume an unfolded front position extending in a forward direction away from the cart in response to movement of the cart pusher about the pivot axis in a counterclockwise direction away from the cart so that the compact collapsible stroller is converted from the compact collapsed storage mode to the expanded use mode. |
