Abstract

A foldable stroller has a frame assembly with a fold joint, a fold joint, a handle push arm, a front leg with an upper end connected to the fold joint, a rear leg extending down from and pivotally connected to the fold joint, and a drive link. The drive link has a rear end pivotally coupled to the rear leg below the fold joint and a front end pivotally coupled to a lower end of the push arm. The frame assembly is reconfigurable between an unfolded and a folded configuration. In the folded configuration, the fold joint moves upward along the handle push arm. The rear end of the drive link and the rear leg are moved toward and lie closely adjacent the front leg and handle push arm. The frame assembly may automatically move to the folded and/or unfolded configuration. The foldable stroller may also stand upright in the folded configuration.
