Abstract

A child carrier apparatus comprises first and second leg frames, a seat frame including first and second tube portions, a joint housing connected with the first and second tube portions, an impeding part assembled adjacent to the joint housing, and a release actuator. The first tube portion is pivotally connected with the first leg frame. The second tube portion is pivotally connected with the second leg frame and the joint housing, and is rotatable between unfolded and folded positions. The impeding part can move between a first position obstructing rotation of the second tube portion relative to the joint housing from the unfolded position, and a second position displaced away from a path of rotation of the second tube portion to allow folding of the second tube portion. The release actuator is operable to drive the impeding part to move from the first to second position.

First claim

What is claimed is:

1. A collapsible child carrier apparatus comprising:
a first and a second leg frame;
a seat frame assembled with the first and second leg frames, the seat frame including a first tube portion pivotally connected with the first leg frame, and a second tube portion pivotally connected with the second leg frame;
a joint housing connected with the first and second tube portions, wherein the second tube portion is pivotally connected with the joint housing, the second tube portion being rotatable relative to the joint housing between an unfolded position and a folded position;
an impeding part assembled adjacent to the joint housing, wherein the impeding part is movable between a first position where the impeding part obstructs rotation of the second tube portion relative to the joint housing from the unfolded position, and a second position where the impeding part is displaced away from a path of rotation of the second tube portion relative to the joint housing and the first tube portion to allow folding of the second tube portion;
a seat affixed with the first tube portion, an underside of the seat having a bracket where the impeding part is assembled, the impeding part being movable through the bracket transversally relative to the child carrier apparatus; and
a release actuator operable to drive the impeding part to move from the first position to the second position.

2. The child carrier apparatus according to claim 1 , wherein the impeding part is biased toward the first position by a spring force.

3. The child carrier apparatus according to claim 1 , wherein parts of the first and second tube portions adjacent to the joint housing are substantially aligned and parallel to each other when the second tube portion is in the unfolded position.

4. The child carrier apparatus according to claim 1 , wherein the first tube portion is affixed with the joint housing.

5. The child carrier apparatus according to claim 1 , further including a rotary arm pivotally connected with the bracket, the release actuator being connected with the rotary arm, the bracket having an elongated slot along which a connection shaft respectively connecting with the rotary arm and the impeding part is guided for displacement.

6. The child carrier apparatus according to claim 1 , further including an arresting part assembled with the bracket, the arresting part being movable between a locking position where the arresting part forms an obstruction that blocks displacement of the impeding part from the first position to the second position, and an unlocking position where the obstruction formed by the arresting part is removed from a path of displacement of the impeding part from the first position toward the second position.

7. The child carrier apparatus according to claim 6 , wherein the arresting part has an opening, the arresting part when in the unlocking position has the opening substantially aligned with the path of displacement of the impeding part from the first position toward the second position.

8. The child carrier apparatus according to claim 6 , wherein the arresting part is biased by a spring force toward the locking position.

9. The child carrier apparatus according to claim 6 , further including a second release actuator assembled with the arresting part, the second release actuator being operable to drive the arresting part in movement between the locking position and the unlocking position.

10. The child carrier apparatus according to claim 9 , wherein the arresting part has a sleeve portion, and the second release actuator has a coupling portion pivotally assembled with the sleeve portion and a cam surface that rests in contact with the seat, the second release actuator being operable to rotate relative to the seat about a pivot axis, and the second release actuator and the arresting part being mutually linked in displacement along the pivot axis via a connection shaft assembled at the sleeve portion and the coupling portion.

11. The child carrier apparatus according to claim 10 , wherein the seat has a raised portion, and the second release actuator is adapted to engage with the raised portion to hold the arresting part in the unlocking position.

12. The child carrier apparatus according to claim 9 , wherein the second leg frame drives the second release actuator in rotation to cause the arresting part to recover the locking position, when the child carrier apparatus is folded.

13. The child carrier apparatus according to claim 9 , wherein the second release actuator is mounted with the seat for transversal movement relative to the seat, the second release actuator having a slot through which a connection shaft mounted with the arresting part is movably assembled, whereby a transversal movement of the second release actuator relative to the seat drives displacement of the arresting part between the locking position and the unlocking position.

14. The child carrier apparatus according to claim 13 , wherein the arresting part has a mount portion, and the release actuator has a knob that is adapted to engage with the mount portion to hold the arresting part in the unlocking position.

15. The child carrier apparatus according to claim 1 , wherein folding of the child carrier apparatus causes the first leg frame and the first tube portion to rotate in a same first direction, and the second leg frame and the second tube portion to rotate in a same second direction opposite the first direction toward the first leg frame and the first tube portion.

16. The child carrier apparatus according to claim 1 , wherein the release actuator is formed by a strap extending across a width of the seat.

17. The child carrier apparatus according to claim 16 , further including a cover made of a fabric material that wraps at least partially the seat and the release actuator, the cover having an opening through which the release actuator is accessible for operation.

18. The child carrier apparatus according to claim 1 , being implemented as a stroller apparatus further including a handle, and an armrest having a transversal portion and a side segment, the second leg frame and the handle being respectively connected pivotally with the side segment, and the first leg frame being affixed with the side segment.

19. The child carrier apparatus according to claim 18 , further including a linkage structure comprised of a rod segment having a first and a second end portion, the first end portion of the rod segment being pivotally connected with the handle, and the second end portion of the rod segment being pivotally connected with the second tube portion.

20. The child carrier apparatus according to claim 19 , wherein the second tube portion is affixed with a holding bracket configured to keep a backrest at different inclinations, and the second end portion of the rod segment is pivotally connected with the holding bracket.

21. The child carrier apparatus according to claim 1 , being implemented as a high chair apparatus.

22. A collapsible child carrier apparatus comprising:
a first and a second leg frame, the first and second leg frame being rotatable toward each other to collapse the child carrier apparatus, and away from each other to unfold the child carrier apparatus;
a seat frame assembled with the first and second leg frames, the seat frame including a first seat frame segment pivotally connected with the first leg frame, and a second seat frame segment pivotally connected with the second leg frame, the
