Abstract

A foldable bassinet apparatus includes a bassinet locking mechanism and a bassinet releasing mechanism. The bassinet releasing mechanism is used to actuate the bassinet locking mechanism. The bassinet locking mechanism includes a first hinge component, a second hinge component, an outer capping component and a locking hub component. The second hinge component is rotatably connected to the first hinge component. The outer capping component is rigidly connected to the second hinge component and configured to cap the first hinge component. The locking hub component is slidably located between the first hinge component and the outer capping component. The locking hub component is fully retracted into the first hinge component to allow relative rotation between the first hinge component and the second hinge component, and is further partially protruded from the first hinge component to constrain the relative rotation.

First claim

What is claimed is:

1. A bassinet locking mechanism for a foldable bassinet apparatus, comprising:
a first hinge component;
a second hinge component rotatably connected to the first hinge component about a rotation axis;
a locking hub component slidably located between the first hinge component and the second hinge component, the locking hub component being fully retracted into the first hinge component to allow relative rotation between the first hinge component and the second hinge component, and being partially protruded from the first hinge component to constrain the relative rotation between the first hinge component and the second hinge component; and
an end of a linkage connected to the locking hub component, wherein the linkage is positioned such that a force applied to the linkage in a direction that is substantially parallel to the rotation axis facilitates retraction of the locking hub component into the first hinge component.

2. The bassinet locking mechanism of claim 1 , wherein the first hinge component comprises at least one first tooth, the second hinge component comprises at least one second tooth, and the locking hub component comprises at least one third tooth engaged between the at least one first tooth and the at least one second tooth to constrain the relative rotation.

3. The bassinet locking mechanism of claim 2 , wherein
while the locking hub component is fully retracted into the first hinge component, the at least one third tooth is disengaged from the second tooth, allowing the relative rotation between the first hinge component and the second hinge component for folding and unfolding the foldable bassinet apparatus; and
while the locking hub component is partially protruded from the first hinge component, the at least one third tooth is engaged with the first tooth and the second tooth to constrain the relative rotation for locking modes of the foldable bassinet apparatus.

4. The bassinet locking mechanism of claim 2 , wherein while the second hinge component is rotated between a folding position and an unfolding position, the second hinge component is rotated relative to the first hinge component and the third tooth is not engaged with the second tooth; and while the second hinge component is rotated to the folding position and the unfolding position, the third tooth is simultaneously engaged with the first tooth and the second tooth.

5. The bassinet locking mechanism of claim 2 , wherein the second hinge component comprises a hinge body and an outer capping component rigidly connected to the hinge body and configured to cap the first hinge component, and the at least one second tooth is located in the outer capping component.

6. The bassinet locking mechanism of claim 2 , wherein the second hinge component comprises a hinge body and an outer capping component detachably connected to the hinge body, and the at least one second tooth is located in the hinge body.

7. The bassinet locking mechanism of claim 1 , further comprising:
a resilient component disposed between the first hinge component and the locking hub component, a resilient recovering force of the resilient component being used to move the locking hub component toward the second hinge component.

8. The bassinet locking mechanism of claim 7 , wherein the resilient component is a compressed spiral spring, an end of the compressed spiral spring abuts against an inner surface of the first hinge component, and the other end of the compressed spiral spring is disposed on a protruding body of the locking hub component.

9. The bassinet locking mechanism of claim 1 , wherein the first hinge component is mounted to a tube, the linkage is a pull wire, an end of the pull wire disposed inside the tube is jointed with the locking hub component, and the locking hub component is pulled by a releasing component via the pull wire to retract into the first hinge component.

10. The bassinet locking mechanism of claim 1 , wherein the locking hub component comprises a main body, a protruding body and a retaining rib, the protruding body and the retaining rib are respectively disposed on a first surface and a second surface of the main body opposite to each other.

11. A bassinet locking mechanism, comprising:
a first hinge component;
a second hinge component rotatably connected to the first hinge component; and
a locking hub component slidably located between the first hinge component and the second hinge component, the locking hub component being fully retracted into the first hinge component to allow relative rotation between the first hinge component and the second hinge component, and being partially protruded from the first hinge component to constrain the relative rotation,
wherein the locking hub component further comprises:
a main body,
a protruding body and a retaining rib, the protruding body and the retaining rib are respectively disposed on a first surface and a second surface of the main body opposite to each other, and
at least one third tooth is disposed on an edge of the main body, the at least one third tooth is configured to engage with the first hinge component and the second hinge component.

12. A bassinet locking mechanism, comprising:
a first hinge component;
a second hinge component rotatably connected to the first hinge component;
a locking hub component slidably located between the first hinge component and the second hinge component, the locking hub component being retracted into the first hinge component to allow relative rotation between the first hinge component and the second hinge component, and being protruded from the first hinge component to constrain the relative rotation, the locking hub component comprises a main body, a protruding body and a retaining rib, the protruding body and the retaining rib are respectively disposed on a first surface and a second surface of the main body opposite to each other; and
an end of a pull wire passes through a channel formed between the main body and the protruding body, and is reached to the second surface to abut against the retaining rib.

13. A bassinet releasing mechanism applied to a tube connected with a locking hub component, the bassinet releasing mechanism comprising:
a pull wire located inside the tube, and an end of the pull wire being jointed with the locking hub component positioned at an end of the tube, the locking hub component being biased into engagement with a hinged locking mechanism having a rotation axis substantially parallel to a direction of the tube; and
a releasing component jointed with the other end of the pull wire, the releasing component being actuated to pull the pull wire for guiding motion of the locking hub component towards the tube in a direction substantially parallel to the rotation axis to release the locking engagement between the locking hub component and the hinged locking mechanism.

14. The bassinet releasing mechanism of claim 13 , further comprising:
a handle disposed on the tube; and
a pressing component movably disposed on the handle and configured to drive motion of the releasing component.

15. The bassinet releasing mechanism of claim 14 , wherein the releasing component is a rotary plate rotatably disposed on the handle.

16. The bassinet releasing mechanism of claim 14 , wherein the pressing component has a bearing surface configured to contact against a protruding portion of the releasing component.

17. The bassinet releasing mechanism of claim 16 , wherein the pressing component is linearly slid relative to the handle to rotate the releasing component via contact bet
