Abstract

A child stroller apparatus includes a handle frame having a first side segment, a first leg frame having a second side segment, a second leg frame, a linkage assembly connected with the handle frame and the second leg frame, and a latching mechanism. The second side segment is connected with a joining part, and the first side segment is connected pivotally with the joining part. Moreover, a handle is disposed adjacent to the joining part and connected with the joining part. The latching mechanism includes a latch assembled with the second side segment, and a release actuator assembled adjacent to the handle and operatively connected with the latch. The latch can engage with the linkage assembly for locking the child stroller apparatus in an unfolded state, and the release actuator is operable to urge the latch to disengage from the linkage assembly for folding the child stroller apparatus.

First claim

What is claimed is:

1. A child stroller apparatus comprising:
a handle frame having a first side segment;
a first leg frame having a second side segment, and a second leg frame having a third side segment, wherein the second side segment is connected fixedly with a joining part, and the first side segment and the third side segment are respectively connected pivotally with the joining part;
a handle disposed adjacent to the joining part and connected fixedly with the joining part;
a linkage assembly connected with the handle frame, the first leg frame and the second leg frame; and
a latching mechanism including a latch assembled with the second side segment, and a release actuator that is assembled adjacent to the handle and is operatively connected with the latch, the latch being operable to engage with the linkage assembly for locking the child stroller apparatus in an unfolded state, and the release actuator being operable to urge the latch to disengage from the linkage assembly for movement of the child stroller apparatus between the unfolded state and a folded state;
wherein the joining part includes a first coupling portion pivotally connected with the first side segment, a second coupling portion fixedly connected with the second side segment, and a third coupling portion pivotally connected with the third side segment, the handle being respectively connected with the first and second coupling portions, the handle and the first and second coupling portions at least partially delimiting an opening for passage of a caregiver's hand for grasping the handle.

2. The child stroller apparatus according to claim 1 , wherein the joining part including the first, second and third coupling portions are formed integrally as a single part.

3. The child stroller apparatus according to claim 1 , wherein the linkage assembly comprises a sliding sleeve and a first and a second side bar, the sliding sleeve being assembled for sliding movement along the second side segment, the first side bar being respectively connected pivotally with the sliding sleeve and the first side segment, and the second side bar being respectively connected pivotally with the sliding sleeve and the third side segment, the latch engaging with the sliding sleeve to lock the child stroller apparatus in the unfolded state.

4. The child stroller apparatus according to claim 3 , wherein the sliding sleeve slides away from the joining part during folding of the child stroller apparatus, and toward the joining part during unfolding of the child stroller apparatus.

5. The child stroller apparatus according to claim 3 , further comprising a second latch disposed on the second side segment, the second latch engaging with the sliding sleeve for locking the child stroller apparatus in the folded state.

6. The child stroller apparatus according to claim 3 , further comprising a seat assembly including a seat bar, a support bar and a backrest frame, the seat bar being respectively connected pivotally with the second side segment and the support bar, the support bar being further pivotally connected with the second side bar.

7. The child stroller apparatus according to claim 1 , wherein the release actuator is movable relative to the handle between an initial position where the release actuator protrudes outside the handle, and a depressed position where the release actuator is displaced toward an interior of the handle, the release actuator moving from the initial position to the depressed position for unlocking the child stroller apparatus.

8. The child stroller apparatus according to claim 7 , wherein the latching mechanism further comprises a spring respectively connected with the release actuator and the handle, the spring biasing the release actuator toward the initial position.

9. The child stroller apparatus according to claim 1 , wherein the release actuator is pivotally connected with the handle.

10. The child stroller apparatus according to claim 1 , wherein the latching mechanism further comprises a driving part that is movably linked to the latch via a sliding connection, and a wire that is respectively connected with the driving part and the release actuator.

11. The child stroller apparatus according to claim 10 , wherein the driving part is assembled with the second side segment for sliding along a direction of extension of the second side segment, and the latch is assembled with the second side segment for sliding substantially perpendicular to the second side segment.

12. The child stroller apparatus according to claim 11 , wherein the sliding connection includes an inclined slot provided on the driving part, and a pin fixedly connected with the latch and slidably received through the inclined slot.

13. The child stroller apparatus according to claim 10 , wherein the latching mechanism further comprises a second spring connected with the driving part, the second spring biasing the driving part in a direction for urging the latch to a locking position.

14. A child stroller apparatus comprising:
a handle frame having a first side segment;
a first and a second leg frame respectively having a second and a third side segment, wherein the second side segment is fixedly connected with a joining part, and the first and third segments are respectively connected pivotally with the joining part, the joining part including at least two coupling portions respectively connected pivotally with the first and third side segments;
a handle disposed adjacent to the joining part and fixedly connected with the joining part, the two coupling portions and the handle at least partially delimiting an opening for passage of a caregiver's hand for grasping the handle;
a linkage assembly respectively connected with the handle frame, the first and second leg frames; and
a latching mechanism including a latch assembled with the second side segment, and a release actuator that is assembled adjacent to the handle and is operatively connected with the latch, the latch being operable to engage with the linkage assembly for locking the child stroller apparatus in an unfolded state, and the release actuator being operable to urge the latch to disengage from the linkage assembly for movement of the child stroller apparatus between the unfolded state and a folded state.

15. The child stroller apparatus according to claim 14 , wherein the release actuator is movable relative to the handle between an initial position where the release actuator protrudes outside the handle and inside the opening, and a depressed position where the release actuator is displaced toward an interior of the handle, the release actuator moving from the initial position to the depressed position for unlocking the child stroller apparatus.

16. The child stroller apparatus according to claim 14 , wherein the linkage assembly comprises a sliding sleeve and a first and a second side bar, the sliding sleeve being assembled for sliding movement along the second side segment, the first side bar being respectively connected pivotally with the sliding sleeve and the first side segment, and the second side bar being respectively connected pivotally with the sliding sleeve and the third side segment, the latch engaging with the sliding sleeve to lock the child stroller apparatus in the unfolded state.

17. The child stroller apparatus according to claim 14 , wherein the joining part and the handle are formed integrally as a single part.
