Abstract

A wheeled carrying apparatus includes a standing frame, a handle frame, a wheel mount, a locking assembly and a release mechanism. The handle frame is rotatable between a first and a second position. The wheel mount carries a wheel and is rotatable relative to the standing frame for changing an orientation of the wheel axis. The locking assembly is configured to rotationally lock the wheel mount with respect to the standing frame, and configured to unlock the wheel mount so that the wheel mount is rotatable relative to the standing frame for changing an orientation of the wheel axis. The release mechanism includes a first portion provided on the standing frame and coupled to the locking mechanism, and a second portion carried with the handle frame, the second portion being movable along with the handle frame toward and away from the first portion during rotation of the handle frame.

First claim

What is claimed is:

1. A wheeled carrying apparatus comprising:
a standing frame and a handle frame pivotally coupled to each other, the handle frame being rotatable relative 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 connected with the standing frame, the locking assembly being configured to rotationally lock the first wheel mount with respect to the standing frame; and
a release mechanism synchronously moved with the handle to couple or decouple with the locking assembly, wherein the release mechanism includes a first portion provided on the standing frame and coupled to the locking assembly, and a second portion carried with the handle frame, the second portion being movable along with the handle frame during rotation of the handle frame between a first position and a second position;
wherein the second portion is operable to actuate the first portion and cause the locking assembly to unlock the first wheel mount when the handle frame is in the first position, and the second portion is decoupled from the first portion so that the second portion is inoperable to cause the locking assembly to unlock the first wheel mount when the handle frame is in the second position.

2. The wheeled carrying apparatus according to claim 1 , wherein causing the locking assembly to unlock the first wheel mount allows the first wheel mount to rotate relative to the standing frame for changing an orientation of the first wheel axis.

3. The wheeled carrying apparatus according to claim 1 , wherein the second portion is located adjacent to the first portion so that the second portion is operable to actuate the first portion and cause the locking assembly to unlock the first wheel mount when the handle frame is in the first position, and the second portion is displaced away and disconnected from the first portion so that the second portion is inoperable to cause the locking assembly to unlock the first wheel mount when the handle frame is in the second position.

4. The wheeled carrying apparatus according to claim 1 , wherein the locking assembly includes a first wheel mount latch movably connected with the standing frame, the first wheel mount latch being movable to engage with the first wheel mount for rotationally locking the first wheel mount with respect to the standing frame and to disengage from the first wheel mount for rotation of the first wheel mount relative to the standing frame.

5. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism is symmetrically arranged on the handle frame.

6. The wheeled carrying apparatus according to claim 1 , wherein the release mechanism is coupled to a distal end of a side portion of the handle frame.

7. The wheeled carrying apparatus according to claim 6 , wherein the release mechanism extends in a direction parallel to an extension direction of the side portion of the handle frame.

8. A wheeled carrying apparatus comprising:
a standing frame and a handle frame pivotally coupled to each other, the handle frame being rotatable relative 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 connected with the standing frame, the locking assembly being configured to rotationally lock the first wheel mount with respect to the standing frame; and
a release mechanism synchronously moved with the handle to couple or decouple with the locking assembly, wherein the release mechanism includes a first portion provided on the standing frame and coupled to the locking assembly, and a second portion carried with the handle frame, the second portion being movable along with the handle frame during rotation of the handle frame between a first position and a second position;
the first portion includes a link actuator that is coupled to the locking assembly via a first linking part, and the second portion includes a driving part and an operating part that are coupled to each other via a second linking part, the driving part being located adjacent to the link actuator when the handle frame is in the first position and is displaced away from the link actuator when the handle frame is in the second position.

9. The wheeled carrying apparatus according to claim 8 , wherein the driving part is movably connected with a side portion of the handle frame.

10. The wheeled carrying apparatus according to claim 8 , wherein the handle frame has a side portion and a grip portion connected with each other, the driving part being movably connected with the side portion, and the operating part being provided on the grip portion.

11. The wheeled carrying apparatus according to claim 8 , wherein any one of the first linking part and the second linking part includes a cable.

12. The wheeled carrying apparatus according to claim 8 , wherein the first linking part loops around a pulley.

13. The wheeled carrying apparatus according to claim 8 , wherein the link actuator is connected with a spring, the spring biasing the link actuator in a direction that urges the link actuator in contact with the driving part.

14. The wheeled carrying apparatus according to claim 8 , wherein the standing frame includes a carrier bar pivotally connected with the handle frame, the link actuator being movably connected and carried with the carrier bar.
