ABSTRACT:
A collapsible stroller has a frame assembly that is reconfigurable between an in-use configuration and a collapsed configuration. The frame assembly has a fold latch on a side of the frame assembly and has two latch parts that are pivotally coupled to one another. A plunger is slidable within a cavity in one of the latch parts and has an end extendible from the cavity. A receiver in the other of the latch parts is positioned to receive the end of the plunger in the in-use configuration. A push arm of the frame assembly has a lower end that is connected to the one latch part. The push arm extends upward and rearward to a handle of the frame assembly. A front leg of the frame assembly has a lower end and extends upward and rearward to an upper end that is connected to the other of the latch parts. A support strut of the frame assembly has an upper end that is pivotally coupled to the one latch part at a pivot defining a pivot axis. The plunger has an elongate slot that is aligned with the pivot axis such that the pivot extends through the slot.
