Abstract

A playpen includes a plurality of standing legs, an upper frame assembly coupled with the standing legs and having an unfolded state and a folded state, and a locking mechanism for locking the upper frame assembly in the unfolded state. The upper frame assembly includes a corner joining part, a middle joining part, and a bar respectively connected pivotally with the corner joining part and the middle joining part about a first and a second pivot axis, the first and second pivot axes extending substantially vertically when the playpen stands on a floor surface.

First claim

What is claimed is:

1. A playpen comprising:
a plurality of standing legs;
an upper frame assembly coupled with the standing legs and having an unfolded state and a folded state, the upper frame assembly having a first side frame portion and a second side frame portion connecting with each other at a corner of the upper frame assembly, wherein the first side frame portion includes a corner joining part and a first bar fixedly connected with each other, and the second side frame portion includes a middle joining part, and a second bar respectively connected pivotally with the corner joining part and the middle joining part about a first and a second pivot axis, the first and second pivot axes extending substantially vertically when the playpen stands on a floor surface, the corner joining part further being pivotally connected with an end of a first one of the standing legs, the first standing leg being rotatable relative to the corner joining part between a folded position where the first standing leg is folded toward the upper frame assembly and an unfolded position where the first standing leg is deployed for providing standing support on a floor surface; and
a locking mechanism for locking the upper frame assembly in the unfolded state;
wherein the corner joining part includes two opposite sidewalls that extend downward from the first bar and delimit at least partially a cavity adjacent to the first bar, the end of the first standing leg being movable inside the cavity between the two sidewalls as the first standing leg rotates relative to the corner joining part.

2. The playpen according to claim 1 , wherein the second bar is fixedly connected with a coupling part having a curved shape that is pivotally connected with the corner joining part about the first pivot axis.

3. The playpen according to claim 1 , wherein the corner joining part and the first bar of the first side frame portion are provided at a first side of the upper frame assembly that is not foldable, and the middle joining part and the second bar are provided at a second side of the upper frame assembly that is foldable.

4. The playpen according to claim 1 , wherein the locking mechanism is carried with the middle joining part.

5. The playpen according to claim 4 , wherein the locking mechanism includes a latch movable relative to the middle joining part between a locking position where the latch engages with the second bar for locking the upper frame assembly in the unfolded state, and an unlocking position where the latch is disengaged from the second bar for movement of the upper frame assembly between the unfolded state and the folded state.

6. The playpen according to claim 5 , wherein the second bar has an end coupling part provided with an extension, the latch being engaged with the extension of the end coupling part in the locking position.

7. The playpen according to claim 5 , wherein the locking mechanism further includes a spring connected with the latch, the spring being configured to bias the latch toward the locking position.

8. The playpen according to claim 5 , wherein the latch has an actuating portion exposed for operation, the actuating portion being operable to cause the latch to move from the locking position to the unlocking position.

9. The playpen according to claim 8 , wherein the actuating portion is formed integrally with the latch.

10. The playpen according to claim 1 , further including a second locking mechanism disposed adjacent to the corner joining part, the second locking mechanism having a latch operable to lock the first standing leg in the unfolded position and unlock the first standing leg for rotation of the first standing leg between the unfolded position and the folded position.

11. A playpen comprising:
a plurality of standing legs;
an upper frame assembly coupled with the standing legs and having an unfolded state and a folded state, wherein the upper frame assembly has a side frame portion including two bars that are respectively connected pivotally with a middle joining part about two pivot axes, the two pivot axes extending substantially vertically when the playpen stands on a floor surface; and
a locking mechanism for locking the upper frame assembly in the unfolded state, wherein the locking mechanism includes a latch carried with the middle joining part, the latch being movable relative to the middle joining part and the two bars between a locking position where the latch engages with the two bars for locking the upper frame assembly in the unfolded state, and an unlocking position where the latch is disengaged from the two bars so that the two bars are movable relative to the middle joining part and the disengaged latch for switching the upper frame assembly between the unfolded state and the folded state;
wherein the latch has a locking portion disposed in a gap between the two pivot axes, and each of the two bars has an end coupling part provided with an extension in the gap between the two pivot axes, the locking portion of the latch being movable in the gap to engage with and disengage from the extension of the end coupling part of each of the two bars.

12. The playpen according to claim 11 , wherein the locking mechanism further includes a spring connected with the latch, the spring being configured to bias the latch toward the locking position.

13. The playpen according to claim 11 , wherein the latch has an actuating portion exposed for operation, the actuating portion being operable to cause the latch to move from the locking position to the unlocking position.

14. The playpen according to claim 13 , wherein the actuating portion is formed integrally with the latch.

15. The playpen according to claim 11 , wherein the upper frame assembly further has a second side frame portion that is connected with the side frame portion via a corner joining part, the side frame portion defining a first side of the upper frame assembly that is foldable, and the second side frame portion defining a second side of the upper frame assembly that is not foldable.

16. The playpen according to claim 15 , wherein the standing legs include a first standing leg pivotally connected with the corner joining part, the first standing leg being rotatable relative to the corner joining part between a folded position where the first standing leg is folded toward the upper frame assembly and an unfolded position where the first standing leg is deployed for providing standing support on a floor surface.

17. The playpen according to claim 16 , further including a second locking mechanism disposed adjacent to the corner joining part, the second locking mechanism having a latch operable to lock the first standing leg in the unfolded position and unlock the first standing leg for rotation of the first standing leg between the unfolded position and the folded position.
