Abstract

An infant stroller apparatus includes a front leg frame having a first side segment, a handle frame having a second side segment pivotally coupled with the first side segment via a first pivot connection, a rear leg frame having a third and a fourth side segment pivotally coupled with each other via a second pivot connection, the third side segment being further pivotally coupled with the first side segment via a third pivot connection, and the fourth side segment being further pivotally coupled with the second side segment via a fourth pivot connection, a seat portion pivotally coupled with the first side segment via a fifth pivot connection, and a support frame portion respectively coupled with the seat portion and the fourth side segment.

First claim

What is claimed is:

1. An infant stroller apparatus comprising:
a front leg frame having a first side segment;
a handle frame having a second side segment pivotally coupled with the first side segment via a first pivot connection;
a rear leg frame having a third and a fourth side segment pivotally coupled with each other via a second pivot connection, the third side segment being further pivotally coupled with the first side segment via a third pivot connection, and the fourth side segment being further pivotally coupled with the second side segment via a fourth pivot connection;
a seat portion pivotally coupled with the first side segment via a fifth pivot connection;
a support frame portion respectively coupled with the seat portion and the fourth side segment;
a latch assembled with the seat portion, the latch being movable to engage with the support frame portion for locking the infant stroller apparatus in an unfolded state, and to disengage from the support frame portion for movement of the infant stroller apparatus between the unfolded state and a collapsed state; and
a release actuator pivotally connected with the seat portion and operatively connected with the latch, the release actuator being rotatable in either direction relative to the seat portion to cause the latch to move for disengaging from the support frame portion.

2. The infant stroller apparatus according to claim 1 , wherein the rear leg frame has a rear wheel assembly, and the second pivot connection is located near the rear wheel assembly.

3. The infant stroller apparatus according to claim 1 , wherein the support frame portion is pivotally coupled with the fourth side segment via a sixth pivot connection that is located between the second and fourth pivot connections.

4. The infant stroller apparatus according to claim 3 , wherein the support frame portion is further pivotally coupled with the seat portion via a seventh pivot connection.

5. The infant stroller apparatus according to claim 3 , wherein the first pivot connection is located above the third pivot connection and the sixth pivot connection when the infant stroller apparatus is in the unfolded state.

6. The infant stroller apparatus according to claim 1 , wherein the first pivot connection is located vertically between the third pivot connection and the fourth pivot connection when the infant stroller apparatus is in the unfolded state.

7. The infant stroller apparatus according to claim 1 , wherein the first side segment, the second side segment, the third side segment and the fourth side segment define a triangular frame geometry when the infant stroller apparatus is in the unfolded state, the second, third and fourth pivot connections being respectively adjacent to three apexes of the triangular frame geometry.

8. The infant stroller apparatus according to claim 1 , wherein the third and fourth side segments are positioned substantially parallel and adjacent to each other between the first side segment and the second side segment when the infant stroller apparatus is in the collapsed state.

9. The infant stroller apparatus according to claim 1 , wherein the latch is further operable to engage with the support frame portion for locking the infant stroller apparatus in the collapsed state.

10. The infant stroller apparatus according to claim 9 , wherein the latch includes a first and a second locking portion respectively disposed at two sides of a pivot connection that pivotally couples the support frame portion with the seat portion, the first locking portion of the latch engaging with the support frame portion for locking the infant stroller apparatus in the unfolded state, and the second locking portion of the latch engaging with the support frame portion for locking the infant stroller apparatus in the collapsed state.

11. The infant stroller apparatus according to claim 10 , wherein the seat portion has a seat surface, and the support frame portion is restrictedly positioned between the seat surface and the first locking portion of the latch in the unfolded state, and between the seat surface and the second locking portion of the latch in the collapsed state.

12. The infant stroller apparatus according to claim 1 , wherein the latch is slidable along an axis extending transversally from a left to a right side of the seat portion.

13. The infant stroller apparatus according to claim 1 , wherein the seat portion has an opening, and the release actuator is disposed in the opening of the seat portion.

14. The infant stroller apparatus according to claim 1 , wherein the support frame portion is pivotally coupled with the seat portion about a pivot axis, and the release actuator is pivotally connected with the seat portion at a rearward location relative to the pivot axis.

15. The infant stroller apparatus according to claim 1 , further including a linking part connected with the release actuator and assembled with the seat portion for sliding along a lengthwise axis extending from a rear to a front of the seat portion, the linking part having a sliding contact with the latch, the release actuator being rotatable relative to the seat portion to urge the linking part to slide and cause the latch to disengage from the support frame portion.

16. The infant stroller apparatus according to claim 15 , wherein the linking part has a slot defining a first and a second ramp surface connected with each other at an inflection region of the slot, and the latch has a protrusion in sliding contact with the slot, the protrusion being in the inflection region when the latch is engaged with the support frame portion, and the protrusion sliding away from the inflection region and in contact with the first or second ramp surface when the latch disengages from the support frame portion.

17. The infant stroller apparatus according to claim 1 , wherein the support frame portion is a basket frame.

18. An infant stroller apparatus comprising:
a front leg frame;
a handle frame pivotally coupled with the front leg frame;
a rear leg frame having two side segments respectively coupled pivotally with the front leg frame and the handle frame;
a seat portion pivotally coupled with the front leg frame;
a support frame portion respectively coupled pivotally with the seat portion and the rear leg frame; and
a latch assembled with the seat portion, the latch being movable to engage with the support frame portion to lock the infant stroller apparatus in an unfolded state and a collapsed state, the latch being further movable to disengage from the support frame portion for movement of the infant stroller apparatus between the unfolded state and the collapsed state.

19. The infant stroller apparatus according to claim 18 , wherein the rear leg frame has a rear wheel assembly, and the two side segments are pivotally connected with each other at a location near the rear wheel assembly.

20. The infant stroller apparatus according to claim 19 , wherein the two side segments of the rear leg frame are positioned substantially parallel and adjacent to each other between the front leg frame and the handle frame when the infant stroller apparatus is in the collapsed state.

21. The infant stroller apparatus according to claim 18 , wherein the latch includes a first and a second locking portion respectively disposed at two sides of a pivot connection that pivotally couples the support frame portion with the seat portion, the first locking portion of the latch engaging with the support frame portion for locking
