Abstract:
1. A collapsible stroller frame having a front and a back, the stroller frame comprising: a spine having a base part and an extension part telescopically connected with a forward end of the base part, the spine positioned generally along a center lengthwise axis of the stroller frame with the forward end coinciding with the front of the stroller frame and a rear end elevated above the forward end and coinciding with the back of the stroller frame, the base and extension parts being slidable between a shortened length in a collapsed configuration and an extended length in a ready for use configuration; a pair of rear legs each having a proximal end near the spine and a distal end portion located below, laterally outward, and rearward of the respective proximal end in a ready for use position, the distal ends being laterally spaced apart in the ready for use position; a seat frame coupled to the stroller frame and positioned on the top side of the spine; and a drive mechanism carried by the spine and actuated by relative sliding movement of the base and extension parts, the drive mechanism drawing the extension part toward the base part when the stroller is moved from the extended length to the shortened length and the drive mechanism drawing the extension part away from the base part when moved from the shortened length to the extended length, and the drive mechanism being connected with the proximal ends of the rear legs such that sliding the base and extension parts from the extended length to the shortened length drives the pair of rear legs inward toward one another and upward toward the underside of the spine to a collapsed position.
