Abstract

A child stroller apparatus includes a handle frame having a first side segment fixedly connected with a first coupling part, a front leg frame having a second side segment fixedly connected with a second coupling part, a rear leg frame having a third side segment fixedly connected with a shell, the third side segment being respectively connected pivotally with the first and second coupling parts, a linking member received at least partially inside the shell and respectively connected pivotally with the first and second coupling parts about two different pivot axes, the handle frame and the front leg frame being thereby rotationally linked to each other, and a latch disposed adjacent to the first coupling part, the latch being operable to rotationally lock the handle frame with respect to the rear leg frame so as to lock the infant stroller apparatus in an unfolded state.

First claim

What is claimed is:

1. A child stroller apparatus comprising:
a handle frame having a first side segment fixedly connected with a first coupling part;
a front leg frame having a second side segment fixedly connected with a second coupling part;
a rear leg frame having a third side segment fixedly connected with a shell, the third side segment being respectively connected pivotally with the first and second coupling parts;
a linking member received at least partially inside the shell and respectively connected pivotally with the first and second coupling parts about two different pivot axes, the handle frame and the front leg frame being thereby rotationally linked to each other;
a latch disposed adjacent to the first coupling part, the latch being operable to rotationally lock the handle frame with respect to the rear leg frame so as to lock the infant stroller apparatus in an unfolded state, wherein the latch is assembled with the shell and is movable to engage with or disengage from the first coupling part; and
an actuating arm that is exposed outside the shell and is pivotally connected with the latch, the actuating arm and the latch further being respectively connected pivotally with the shell, a rotation of the actuating arm in one direction urging the latch to rotate and disengage from the first coupling part.

2. The child stroller apparatus according to claim 1 , wherein the linking member is pivotally connected with the second coupling part via a pivot connection, the pivot connection moving inside the shell when the child stroller apparatus is switched between the unfolded state and a folded state.

3. The child stroller apparatus according to claim 1 , wherein the linking member is respectively connected pivotally with the first and second coupling parts via two pivot connections, the two pivot connections moving inside the shell when the child stroller apparatus is switched between the unfolded state and a folded state.

4. The child stroller apparatus according to claim 1 , further including a seat mount fixedly attached to the shell, the seat mount being configured to receive a detachable installation of a child seat.

5. The child stroller apparatus according to claim 1 , further including a safety lock mechanism configured to prevent accidental folding of the child stroller apparatus, the safety lock mechanism including an impeding part connected with the shell, the impeding part being movable to engage or disengage the actuating arm, an engagement of the impeding part with the actuating arm blocking movement of the actuating arm in a direction that causes unlocking of the latch.

6. The child stroller apparatus according to claim 1 , further including a safety lock mechanism configured to prevent accidental folding of the child stroller apparatus, the safety lock mechanism including an impeding part exposed outward and assembled with the first side segment, the impeding part being operable independent from the latch, an engagement of the impeding part with the shell blocking rotation of the handle frame in a folding direction.

7. A child stroller apparatus comprising:
a handle frame having a first side segment fixedly connected with a first coupling part;
a front leg frame having a second side segment fixedly connected with a second coupling part;
a rear leg frame having a third side segment fixedly connected with a shell, the third side segment being respectively connected pivotally with the first and second coupling parts;
a linking member received at least partially inside the shell and respectively connected pivotally with the first and second coupling parts about two different pivot axes, the handle frame and the front leg frame being thereby rotationally linked to each other;
a latch assembled with the shell, the latch being engaged with the first coupling part to lock the infant stroller apparatus in an unfolded state, and the latch disengaging from the first coupling part for folding of the child stroller apparatus;
a release actuator movably assembled with the shell for rotational movement, the latch and the release actuator respectively having ramp surfaces in contact with each other, the release actuator being movable upward to cause an unlocking displacement of the latch for disengaging from the first coupling part; and
a safety lock mechanism configured to prevent accidental folding of the child stroller apparatus, the safety lock mechanism including an impeding part assembled with the release actuator, the impeding part being movable relative to the release actuator to protrude outward and engage with the shell for blocking upward displacement of the release actuator, or to retract inward and disengage from the shell.

8. The child stroller apparatus according to claim 7 , wherein the latch is connected with a spring, the spring biasing the latch to a locking state.

9. The child stroller apparatus according to claim 7 , wherein the linking member is respectively connected pivotally with the first and second coupling parts via two pivot connections, the two pivot connections moving inside the shell when the child stroller apparatus is switched between the unfolded state and a folded state.

10. The child stroller apparatus according to claim 7 , further including a seat mount fixedly attached to the shell, the seat mount being configured to receive a detachable installation of a child seat.

11. The child stroller apparatus according to claim 7 , wherein the release actuator is further fixedly connected with a transversal bar assembly, and the safety lock mechanism further includes a release part that is disposed on the transversal bar assembly and is operatively connected with the impeding part via a cable, the release part being operable to urge the impeding part to move and disengage from the shell.

12. A child stroller apparatus comprising:
a handle frame having a first side segment fixedly connected with a first coupling part;
a front leg frame having a second side segment that is fixedly connected with a second coupling part;
a rear leg frame having a third side segment that is fixedly connected with a third coupling part, the third coupling part being respectively connected pivotally with the first and second coupling parts;
a first and a second shell respectively connected fixedly with the third coupling part and the first coupling part, the first coupling part being received at least partially in the second shell, the third coupling part being received at least partially in the first and second shells;
a linking member received at least partially inside the first and second shells and respectively connected pivotally with the first and second coupling parts about two different pivot axes, the handle frame and the front leg frame being thereby rotationally linked to each other; and
a latch assembled with the first coupling part, the latch being engaged with the third coupling part to lock the child stroller apparatus in an unfolded state, and the latch disengaging from the third coupling part for folding of the child stroller apparatus.

13. The child stroller apparatus according to claim 12 , wherein the linking member is connected pivotally with the second coupling part via a pivot connection, the pivot connection moving inside the first shell when the child stroller apparatus is switched between the unfolded state and a folded state.

14. The child stroller apparatus according to claim 12 , wherein the latch is slidably assembled with the first coupling part and is connected with a spring, the spring biasing the latch for engagement with the third coupling part.

15. The child st
