Abstract

Official abstract text for this publication.

A child stroller apparatus includes a rear and a front leg frame respectively having a first and a second side segment, a handle frame having a grip portion and a third side segment respectively connected fixedly with a first and a second joining part that are pivotally connected with each other, a latching mechanism for locking the rear and front leg frames and the handle frame in an unfolded state, and a latch carried with the third side segment. The latch can engage and disengage the first joining part to lock and unlock the grip portion relative to the third side segment. Moreover, a linking part couples the latch to the rear leg frame or the front leg frame so that a folding rotation of the handle frame relative to the rear leg frame causes the latch to disengage from the first joining part.

First claim

Opening claim text (preview).

What is claimed is: 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. 2. The child stroller apparatus according to claim 1 , further comprising: a spring operable to bias the latch to engage with the first joining part. 3. The child stroller apparatus according to claim 1 , wherein the first, second and third side segments are respectively connected fixedly with a first coupling part, a second coupling part and a third coupling part, the second and third coupling parts being respectively connected pivotally with the first coupling part, and the linking part including a cable having a first end connected with the latch and a second end connected with the first coupling part, the second coupling part or the latching mechanism. 4. The child stroller apparatus according to claim 3 , wherein the second and third coupling parts are respectively connected pivotally with the first coupling part about two pivot axes spaced apart from each other. 5. The child stroller apparatus according to claim 3 , wherein the third coupling part is pivotally connected with the first coupling part about a pivot axis, and the second end of the cable is anchored to the first coupling part at a location offset from the pivot axis. 6. The child stroller apparatus according to claim 3 , wherein the second and third coupling parts are pivotally connected with a linking member, thereby the front leg frame and the handle frame are rotatable in unison relative to the rear leg frame during folding and unfolding of the child stroller apparatus. 7. The child stroller apparatus according to claim 1 , wherein the first, second and third side segment are respectively connected fixedly with a first, a second and a third coupling part, the second and third coupling parts being respectively connected pivotally with the first coupling part, and the latching mechanism includes a locking part movably connected with the first coupling part, the locking part being movable to engage with the second and third coupling parts for locking the rear and front leg frames and the handle frame in the unfolded state. 8. The child stroller apparatus according to claim 7 , wherein the second and third coupling parts are spaced apart from each other by a gap when the rear and front leg frames and the handle frame are in the unfolded state, the locking part protruding into the gap and respectively engaging with a first edge surface of the second coupling part and a second edge surface of the third coupling part for locking the rear and front leg frames and the handle frame in the unfolded state. 9. The child stroller apparatus according to claim 7 , wherein the latching mechanism further includes a spring operable to bias the locking part for engagement with the second and third coupling parts, and a release actuator connected with the locking part and operable to urge the locking part to disengage from the second and third coupling parts. 10. The child stroller apparatus according to claim 1 , further comprising: a spring operable to bias the grip portion toward the folded position. 11. 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 to a first joining part, and the third side segment being fixedly connected to 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 the latching mechanism so that an unlocking movement of the latching mechanism disengages the latch from the first joining part for unlocking the grip portion. 12. A child stroller apparatus, comprising: a rear leg frame; a front leg frame; a handle frame having lower portion and a grip portion, the front leg frame and the lower portion of the handle frame being connected pivotally to the rear leg frame; a first joining part fixedly connected to the grip portion; a second joining part pivotally connected to the first joining part and fixedly coupled to the lower portion of the handle frame so that the grip portion is movable relative to the lower portion of the handle frame between an unfolded position and a folded position; a latching mechanism operable to lock the rear leg frame, the front leg frame and the handle frame in an unfolded state; a latch coupled to the lower portion of the handle frame, 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 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 to unlock the grip portion, or the linking part coupling the latch to the latching mechanism so that an unlocking movement of the latching mechanism disengages the latch from the first joining part to unlock the grip portion.
