An infant carrier apparatus comprises a support frame, a handle assembly having two side segments, two handle adjusting mechanisms pivotally connecting the two side segments of the handle assembly with the support frame, a release actuator and two transmission elements. Each of the handle adjusting mechanisms has a locked state for securely holding the handle assembly in place relative to the support frame, and an unlocked state allowing rotation of the handle assembly about a pivot axis relative to the support frame. Each of the transmission elements has a first and second distal end, wherein the first distal end is connected with one of the handle adjusting mechanisms, and the second distal end is connected with the release actuator. The release actuator is operable to switch the handle adjusting mechanisms from the locked state to the unlocked state.

1. An infant carrier apparatus comprising: a support frame;a handle assembly having two side segments;two handle adjusting mechanisms pivotally connecting the two side segments of the handle assembly with the support frame, wherein each of the handle adjusting mechanisms has a locked state for securely holding the handle assembly in place relative to the support frame, and an unlocked state allowing rotation of the handle assembly about a pivot axis relative to the support frame;two transmission elements, wherein each of the transmission elements has a first and second distal end, the first distal end being connected with one of the handle adjusting mechanisms; anda release actuator connected with the second ends of the transmission elements, wherein the release actuator is operable to switch the handle adjusting mechanisms from the locked state to the unlocked state;wherein each of the handle adjusting mechanisms includes: a first and a second coupling element pivotally assembled with each other; anda latch device operable to lock the first coupling element with the second coupling element, thereby blocking rotation of the handle assembly relative to the support frame, the latch device including: two latches movably assembled at two radially opposite sides of the pivot axis, wherein the latches are driven in movement toward the pivot axis when the handle adjusting mechanisms are switched from the locked state to the unlocked state. 2. The apparatus according to claim 1, wherein the second coupling element includes a housing in which the two latches are movably assembled. 3. The apparatus according to claim 1, wherein the latches are placed in the second coupling element, the first coupling element includes a plurality of locking slots distributed radially relative to the pivot axis, and the latches engage with two diametrically opposite ones of the locking slots when the handle adjusting mechanisms are in the locked state. 4. The apparatus according to claim 3, wherein the first coupling element includes a guide track in which are defined the locking slots. 5. The apparatus according to claim 4, wherein the guide track includes at least one end stop against which one of the latches comes in abutment for limiting a range of rotation of the second coupling element relative to the first coupling element. 6. The apparatus according to claim 3, wherein each of the latches is connected with a spring element operable to bias the connected latch to engage with one corresponding locking slot. 7. The apparatus according to claim 3, wherein each of the handle adjusting mechanisms further comprises: a rotary plate pivotally assembled about the pivot axis and having two first guide slots located on opposite sides relative to the pivot axis,wherein the two latches are respectively assembled in a movable manner with the two first guide slots, and the rotary plate is connected with the first distal end of one transmission element, whereby when the release actuator is operated to pull on the transmission elements, the rotary plate is driven in rotation about the pivot axis to cause the two latches to disengage from the corresponding locking slots. 8. The apparatus according to claim 7, wherein each of the first guide slots includes a first and second end, the second end being closer to the pivot axis than the first end. 9. The apparatus according to claim 7, wherein each of the latches includes an engagement pin movably assembled through one associated first guide slot of the rotary plate, the engagement pin being engaged with one corresponding locking slot of the guide track when the handle adjusting mechanisms are in the locked state. 10. The apparatus according to claim 7, wherein the transmission elements respectively drive the rotary plates in rotation to cause the latches to displace toward each other when the handle assembly is rotated about the pivot axis. 11. The apparatus according to claim 1, wherein the handle assembly includes a transverse segment connecting between the two side segments, and the release actuator is placed on the transverse segment. 12. The apparatus according to claim 1, wherein the release actuator comprises: a housing having two elongated slots;a button having two second guide slots;wherein the second distal ends of the transmission elements are respectively assembled in a movable manner through the elongated slots and the second guide slots, whereby the button is operable to pull the transmission elements in movement for switching the handle adjusting mechanisms from the locked state to the unlocked state. 13. The apparatus according to claim 1, wherein the infant carrier apparatus is a stroller, and the support frame includes front and rear leg frames having lower ends provided with a plurality of wheels. 14. The apparatus according to claim 13, wherein the handle adjusting mechanisms are connected with the front leg frame. 15. An infant carrier apparatus comprising: a support frame;a handle assembly having a side segment pivotally connected with the support frame about a pivot axis;a handle adjusting mechanism including: two coupling parts respectively assembled with the support frame and the side segment and pivotally connected with each other; andtwo latches assembled at two radially different positions relative to the pivot axis, wherein the latches are operable to lock each other the two coupling parts for blocking rotation of the handle assembly relative to the support frame in a locked state, and the latches are driven in radial movement relative to the pivot axis when the handle adjusting mechanism is switched from the locked state to an unlocked state for allowing rotation of the handle assembly relative to the support frame; anda release actuator operatively coupled with the handle adjusting mechanism via a transmission element, the release actuator being operable to switch the handle adjusting mechanism from the locked state to the unlocked state. 16. The apparatus according to claim 15, wherein the two coupling parts include a first and a second coupling part, the latches are placed in a housing portion of the second coupling part, the first coupling part includes a plurality of locking slots distributed radially relative to the pivot axis, and the latches respectively engage with two ones of the locking slots when the handle adjusting mechanism is in the locked state. 17. The apparatus according to claim 16, wherein the first coupling part includes a guide track in which are defined the locking slots, and the guide track includes at least one end stop against which one of the latches comes in abutment for limiting a range of rotation of the second coupling part relative to the first coupling part. 18. The apparatus according to claim 16, wherein each of the latches is connected with a spring element operable to bias the connected latch to engage with one corresponding locking slot. 19. The apparatus according to claim 16, wherein the handle adjusting mechanism further comprises: a rotary plate pivotally assembled about the pivot axis and having two first guide slots;wherein the two latches are respectively assembled with the two first guide slots, and the rotary plate is connected with an end of the transmission element, whereby when the release actuator is operated to displace the transmission element, the rotary plate is driven in rotation about the pivot axis to cause the two latches to disengage from the corresponding locking slots. 20.
