US Patent 10913478 Outdoor stroller for children

An outdoor stroller for children is disclosed, including a top frame and a bottom frame which are frame units parallel to each other. An upper lateral bar is pivoted with a lower lateral bar which is crossed over and put upright with a crossbar in an X-shape. By the arrestment of a disengaging mechanism and a clamping device, the upper lateral bar and the lower lateral bar are formed into a straight bar to support and level the top frame parallel, thereby unfolding the stroller. On the other hand, the upper lateral bar and the lower lateral bar are turned backward, the top frame is lowered down parallel, and the lower lateral bar and the crossbar that are crossed over in the X-shape are folded with each other, so as to fold the stroller.
