1. A child stroller apparatus, comprising:
a rear leg frame having a first side segment;
a front leg frame having a second side segment, and a handle frame having a third side segment and a grip portion, the second and third side segments being respectively connected pivotally with the first side segment, the grip portion being fixedly connected with a first joining part, and the third side segment being fixedly connected with a second joining part that is pivotally connected with the first joining part, whereby the grip portion is movable relative to the third side segment between an unfolded position and a folded position;, a latching mechanism operable to lock the rear and front leg frames and the handle frame in an unfolded state;
a latch coupled to the third side segment, the latch being engaged with the first joining part to lock the grip portion in the unfolded position and disengaged from the first joining part to unlock the grip portion for movement of the grip portion between the unfolded position and the folded position; and
a linking part coupling the latch to one of the rear leg frame and the front leg frame so that a folding motion of the handle frame relative to the rear leg frame disengages the latch from the first joining part for unlocking the grip portion, or the linking part coupling the latch to the latching mechanism so that an unlocking movement of the latching mechanism causes the latch to disengage from the first joining part for unlocking the grip portion.
