Abstract

An infant stroller apparatus includes a first and a second leg frame respectively having a first and a second side segment respectively connected fixedly with a first and a second coupling part, and a handle frame having a third side segment fixedly connected with a third coupling part. The second and third coupling parts are respectively connected pivotally with the first coupling part. Moreover, the infant stroller apparatus includes a first latch operable to rotationally lock the handle frame with respect to the first leg frame, a second latch operable to rotationally lock the second leg frame with respect to the first leg frame, and a linkage assembly respectively connected with the third coupling part and the second latch such that a folding rotation of the handle frame relative to the first leg frame urges an unlocking displacement of the second latch.
