Abstract

A wheeled carrying apparatus includes a frame structure including a standing frame, a wheel mount carrying a wheel and pivotally connected with the standing frame, the wheel being rotatable relative to the first wheel mount about a wheel axis, a locking assembly including a wheel mount latch movably connected with the standing frame, the wheel mount latch being engaged with the wheel mount to rotationally lock the first wheel mount with respect to the standing frame, and disengaged from the wheel mount to unlock the wheel mount for rotation of the wheel mount to change an orientation of the wheel axis, an actuating assembly coupled to the wheel mount latch and including one or more linking part, and a release mechanism including an operating part provided on the frame structure that is operable to cause the actuating assembly to pull the wheel mount latch to disengage from the wheel mount.

First claim

What is claimed is:

1. A wheeled carrying apparatus comprising:
a frame structure including a standing frame and a handle frame coupled to the standing frame;
a first wheel mount carrying a first wheel and pivotally connected with the standing frame, the first wheel being rotatable relative to the first wheel mount about a first wheel axis;
a locking assembly including a first wheel mount latch movably connected with the standing frame, the first wheel mount latch being adapted to be engaged with the first wheel mount to rotationally lock the first wheel mount with respect to the standing frame, and adapted to be disengaged from the first wheel mount to unlock the first wheel mount so that the first wheel mount is rotatable relative to the standing frame for changing an orientation of the first wheel axis;
an actuating assembly coupled to the first wheel mount latch; and
a release mechanism being operable, independently from operating the handle frame, to cause the actuating assembly to actuate the first wheel mount latch to disengage the first wheel mount latch from the first wheel mount,
wherein
the first wheel mounting latch has an engaging portion configured to be engaged in an opening at an upper surface of the first wheel mount, and
a size of the opening corresponds to the engaging portion of the first wheel mounting latch.

2. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism is operable to cause the actuating assembly to push or pull the first wheel mount latch so that the first wheel mount latch disengages from the first wheel mount.

3. The wheeled carrying apparatus according to claim 1 , wherein the locking assembly includes a locking spring connected with the first wheel mount latch, the locking spring being adapted to apply a biasing force for engaging the first wheel mount latch with the first wheel mount.

4. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism includes an operating part that is optionally placed on the handle frame.

5. The wheeled carrying apparatus according to claim 4 , wherein the operating part is slidably or pivotally connected with the frame structure, in particular with the handle frame.

6. The wheeled carrying apparatus according to claim 1 , wherein the actuating assembly includes a link actuator and a linking part, the link actuator being movably connected with the frame structure, the linking part coupling the first wheel mount latch to the link actuator.

7. The wheeled carrying apparatus according to claim 6 , wherein the link actuator is movable to actuate the linking part, in particular to push or pull the linking part, and to urge the first wheel mount latch to disengage from the first wheel mount.

8. The wheeled carrying apparatus according to claim 6 or 7 , wherein the linking part includes a cable.

9. The wheeled carrying apparatus according to claim 8 , wherein the release mechanism includes an operating part that is coupled to the link actuator via a cable.

10. The wheeled carrying apparatus according to claim 1 , wherein the actuating assembly includes a link actuator and wherein the handle frame is coupled to the standing frame via a bar linkage, the link actuator being movably connected with the bar linkage.

11. The wheeled carrying apparatus according to claim 10 , wherein the bar linkage includes a bar having two ends respectively connected pivotally with the handle frame and the standing frame, and the link actuator is slidably connected with the bar.

12. The wheeled carrying apparatus according to claim 10 , wherein the release mechanism includes an operating part that is placed on the handle frame.

13. The wheeled carrying apparatus according to claim 1 , wherein the actuating assembly includes a link actuator and wherein the link actuator is slidably assembled with the frame structure, and the release mechanism includes an operating part that has a ramp surface, the release mechanism being operable to cause the first wheel mount latch to unlock the first wheel mount via a sliding contact between the ramp surface and the link actuator.

14. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism includes an operating part that includes a barrel pivotally connected with the frame structure, and wherein the actuating assembly includes a linking part, and the linking part includes a cable having an end anchored to the barrel, the barrel being rotatable to wind at least partially the cable so that the first wheel mount latch is actuated in movement by the actuating assembly, in particular pushed or pulled in movement by the actuating assembly, and disengages from the first wheel mount.

15. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism includes an operating part that includes a barrel pivotally connected with the frame structure, and a button slidably connected with the frame structure, and wherein the actuating assembly includes a linking part, and the linking part includes a cable having an end anchored to the barrel, the button being operable to urge the barrel to rotate for operating the cable so that the first wheel mount latch is actuated in movement by the actuating assembly, in particular for pulling the cable so that the first wheel mount latch is pulled in movement by the actuating assembly and disengages from the first wheel mount.

16. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism includes an operating part, and the actuating assembly includes a single cable having two opposite ends respectively connected with the operating part and the first wheel mount latch.

17. The wheeled carrying apparatus according to claim 1 , being implemented as a child stroller apparatus.

18. The wheeled carrying apparatus according to claim 1 , wherein the first wheel mount is configured to, in response to the engaging portion of the first wheel mount latch engaging with the opening at the upper surface of the first wheel mount without changing the orientation of the first wheel axis, be rotationally locked with respect to the standing frame.

19. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism includes an operating part provided on the frame structure at a location distant from the first wheel mount latch.

20. A wheeled carrying apparatus comprising:
a frame structure including a standing frame;
a first wheel mount carrying a first wheel and pivotally connected with the standing frame, the first wheel being rotatable relative to the first wheel mount about a first wheel axis;
a locking assembly including a first wheel mount latch movably connected with the standing frame, the first wheel mount latch being adapted to be engaged with the first wheel mount to rotationally lock the first wheel mount with respect to the standing frame, and adapted to be disengaged from the first wheel mount to unlock the first wheel mount so that the first wheel mount is rotatable relative to the standing frame for changing an orientation of the first wheel axis;
