Abstract
A child stroller apparatus includes a standing frame having a first and a second leg frame, a handle frame pivotally connected with the first leg frame via a joint structure that defines a pivot axis about which the handle frame is rotatable relative to the first leg frame, the handle frame further being pivotally connected with the second leg frame via a pivot connection away from the pivot axis, a first coupling part pivotally connected with the joint structure in a coaxial manner, and a locking mechanism including a front guard latch disposed adjacent to the joint structure. The front guard latch is movable between a locking position where the front guard latch locks the first coupling part to the joint structure, and an unlocking position for rotation of the first coupling part relative to the joint structure.
Claims20
A child stroller apparatus comprising:
- a standing frame including a first and a second leg frame;
- a handle frame, wherein the handle frame is pivotally connected with the first leg frame via a joint structure that defines a pivot axis about which the handle frame is rotatable relative to the first leg frame, and the handle frame is pivotally connected with the second leg frame via a pivot connection away from the pivot axis;
- a first coupling part pivotally connected with the joint structure in a coaxial manner so that the handle frame, the first coupling part and the first leg frame are rotatable relative to one another about the same pivot axis, wherein the joint structure includes a second coupling part fixedly connected with the handle frame, and a third coupling part that is fixedly connected with the first leg frame and is pivotally connected with the second coupling part, the first coupling part being pivotally connected with the second coupling part;
- and
- a locking mechanism including a front guard latch disposed adjacent to the joint structure, the front guard latch being movable between a locking position where the front guard latch locks the first coupling part to the joint structure, and an unlocking position for rotation of the first coupling part relative to the handle frame and the standing frame.
A child stroller apparatus comprising:
- a standing frame;
- a handle frame pivotally coupled to the standing frame via a joint structure;
- a first coupling part pivotally connected with the joint structure;
- a first locking mechanism including a front guard latch disposed adjacent to the joint structure, the front guard latch being movable between a locking position where the front guard latch locks the first coupling part to the joint structure, and an unlocking position for rotation of the first coupling part relative to the joint structure;
- a second locking mechanism including a frame latch disposed inside the joint structure, the frame latch being operable to lock the child stroller apparatus in an unfolded state;
- and
- a release actuator operable to cause the front guard latch and the frame latch to move concurrently in an unlocking direction.
A child stroller apparatus comprising:
- a standing frame including a first and a second leg frame;
- a handle frame, wherein the handle frame is pivotally connected with the first leg frame via a joint structure that defines a pivot axis about which the handle frame is rotatable relative to the first leg frame, and the handle frame is pivotally connected with the second leg frame via a pivot connection away from the pivot axis;
- a first coupling part pivotally connected with the joint structure in a coaxial manner so that the handle frame, the first coupling part and the first leg frame are rotatable relative to one another about the same pivot axis;
- and
- a locking mechanism including a front guard latch disposed adjacent to the joint structure, the front guard latch being movable between a locking position where the front guard latch locks the first coupling part to the joint structure, and an unlocking position for rotation of the first coupling part relative to the handle frame and the standing frame, wherein the front guard latch is configured to slide along the pivot axis between the locking position and the unlocking position.
