Abstract
A collapsible infant's stroller has a pair of elongated tubular side frames each with a front wheel at its lower end. A fabric seat is supported upon the side frames and upon a pair of side struts, with said struts being pivotally connected to the side frames and extending forwardly therefrom. The side struts also extend rearwardly and downwardly from the side frames and have rear wheels connected to their lower ends. A bottom X-frame pivotally interconnects the side frames and the side struts adjacent their respective wheels, and a rear X-frame pivotally interconnects the side struts adjacent the rear wheels with slide lock assemblies on the side frames above the fabric seat. The slide lock assemblies have cam levers receivable in slots in said side frames for locking the stroller in an unfolded operating position. When released from the slots, the slide lock assemblies are slidable along the side frames for moving the stroller to a low-profile folded position with the bottom and rear X-frames disposed end-to-end in substantially the same plane.
