Abstract

An infant stroller apparatus includes a front leg frame, a rear leg frame and a handle frame. The front leg frame has a first side portion fixedly connected with a first stop abutment. The rear leg frame has a second side portion having a protrusion. The handle frame has a side segment fixedly connected with a second stop abutment, the first and second side portions and the side segment being pivotally connected with one another about a common first pivot axis. The protrusion is restrictedly positioned between the first and second stop abutments when the infant stroller apparatus is in a deployed state.

First claim

What is claimed is:

1. An infant stroller apparatus comprising:
a front leg frame having a first side portion, the first side portion being fixedly connected with a first stop abutment;
a rear leg frame having a second side portion, the second side portion having a protrusion; and
a handle frame having a side segment, the first and second side portions and the side segment being pivotally connected with one another about a common first pivot axis, and the side segment of the handle frame being fixedly connected with a second stop abutment;
wherein the protrusion is restrictedly positioned between the first and second stop abutments when the infant stroller apparatus is in a deployed state, respective abuttal of the protrusion against the first and second stop abutments in the deployed state preventing rotation of the rear leg frame relative to the handle frame and the front leg frame.

2. The infant stroller apparatus according to claim 1 , wherein the second stop abutment travels away from the first stop abutment and the protrusion of the second side portion when the handle frame is rotated in a collapsing direction toward the front leg frame.

3. The infant stroller apparatus according to claim 1 , further comprising:
a seat frame pivotally connected with the side segment of the handle frame about a second pivot axis; and
a bar linkage having a first and a second end, the first end being pivotally connected with the second side portion of the rear leg frame about a third pivot axis, and the second end being pivotally connected with the seat frame about a fourth pivot axis;
wherein when the infant stroller apparatus is in the deployed state, the second pivot axis is above the first pivot axis, the third pivot axis is above the first pivot axis, and the fourth pivot axis is above and behind the first pivot axis.

4. The infant stroller apparatus according to claim 3 , wherein when the infant stroller apparatus is in the deployed state, the second pivot axis is located in front of the fourth pivot axis and above and behind the first pivot axis.

5. The infant stroller apparatus according to claim 3 , further including a guard member pivotally connected with the seat frame about the second pivot axis.

6. The infant stroller apparatus according to claim 3 , wherein the seat frame has a rear transversal portion, and the first side portion of the front leg frame and the side segment of the handle frame are connected with each other via a pivot joint, the rear transversal portion of the seat frame being located behind the pivot joint when the infant stroller apparatus is in the deployed state, and the rear transversal portion of the seat frame being displaced to a position adjacent to the pivot joint when the infant stroller apparatus is folded from a deployed state to a collapsed state.

7. The infant stroller apparatus according to claim 3 , wherein the seat frame includes a first and a second frame portion pivotally connected with each other, the first frame portion extending at a front of the seat frame, the second frame portion extending at a rear of the seat frame and further being respectively connected pivotally with the side segment of the handle frame and the second end of the bar linkage.

8. The infant stroller apparatus according to claim 1 , wherein the first side portion of the front leg frame and the side segment of the handle frame are connected with each other via a pivot joint that includes a latch, the pivot joint thereby having a locked state preventing rotation of the handle frame relative to the front leg frame such that the infant stroller apparatus is locked in the deployed state, and the pivot joint further having an unlocked state allowing folding of the handle frame toward the front leg frame.

9. The infant stroller apparatus according to claim 8 , wherein the handle frame has a foldable structure and includes a release actuator operatively connected with the latch of the pivot joint, the release actuator being operable to cause an unlocking displacement of the latch for switching the pivot joint from the locked state to the unlocked state.

10. The infant stroller apparatus according to claim 9 , wherein the release actuator includes a push handle of the handle frame that is pivotally connected with the side segment via a second pivot joint and is connected with the latch via a drawing member, the release actuator when rotated toward the side segment pulls the drawing member and causes an unlocking displacement of the latch.

11. The infant stroller apparatus according to claim 10 , wherein the second pivot joint includes a second latch operable to lock the handle frame in an unfolded state, and a release button exposed on the second pivot joint, the release button being operable to cause a displacement of the second latch to unlock the second pivot joint for rotation of the push handle relative to the side segment.

12. The infant stroller apparatus according to claim 9 , wherein the handle frame further includes a push handle that is pivotally connected with the side segment via a second pivot joint, and the release actuator is assembled with the side segment at a location near the second pivot joint.

13. The infant stroller apparatus according to claim 12 , wherein the push handle is rotatable relative to the side segment in a folding direction to hit the release actuator, thereby causing a movement of the release actuator that drives an unlocking displacement of the latch.

14. The infant stroller apparatus according to claim 13 , wherein the release actuator is connected with a sliding member that is disposed inside the side segment, and the sliding member is connected with the latch via a drawing member, the release actuator when hit by the push handle rotates and drives a displacement of the sliding member that causes unlocking of the latch.

15. The infant stroller apparatus according to claim 13 , wherein the release actuator is connected with a sliding member that is disposed inside the side segment, and the sliding member is connected with the latch via a drawing member, the release actuator when hit by the push handle slides and drives a displacement of the sliding member that causes unlocking of the latch.

16. The infant stroller apparatus according to claim 1 , wherein the first stop abutment is provided on an inner side of the first side portion, and the second stop abutment is provided on an inner side of the side segment.
