Abstract

A playpen includes an upper frame assembly having an unfolded and a folded state, a standing leg rotatable relative to the upper frame assembly between a folded and an unfolded position, a first locking mechanism for locking the standing leg in the unfolded position, and a second locking mechanism for locking the upper frame assembly in the unfolded state. The upper frame assembly includes an unfoldable side frame portion including a corner joining part, and a foldable side frame portion including a coupling part pivotally connected to the corner joining part. The corner joining part includes a cavity delimited at least partially between two opposite sidewalls thereof, and the standing leg has an end pivotally connected to the corner joining part, the end of the standing leg being movable inside the cavity of the corner joining part as the standing leg rotates relative to the corner joining part.

First claim

What is claimed is:

1. A playpen comprising:
an upper frame assembly coupled to at least one standing leg, the upper frame assembly having an unfolded state and a folded state, the standing leg being rotatable relative to the upper frame assembly between a folded position and an unfolded position; and
a first locking mechanism for locking the standing leg in the unfolded position, and a second locking mechanism for locking the upper frame assembly in the unfolded state;
wherein the upper frame assembly comprises:
an unfoldable first side frame portion including a corner joining part; and
a foldable second side frame portion including a coupling part pivotally connected to the corner joining part;
wherein the corner joining part includes a cavity delimited at least partially between two opposite sidewalls of the corner joining part, and the standing leg has an end pivotally connected to the corner joining part via a pivot connection, the end of the standing leg being movable inside the cavity between the two sidewalls of the corner joining part as the standing leg rotates relative to the corner joining part.

2. The playpen according to claim 1 , wherein the coupling part is pivotally connected to the corner joining part about a pivot axis, the pivot axis extending substantially vertically when the playpen stands on a floor surface.

3. The playpen according to claim 1 , wherein the coupling part is pivotally connected to the corner joining part above the pivot connection of the standing leg.

4. The playpen according to claim 1 , wherein the pivot connection of the standing leg is disposed adjacent to the two sidewalls of the corner joining part.

5. The playpen according to claim 1 , wherein the coupling part has a curved shape.

6. The playpen according to claim 1 , wherein the first side frame portion includes a first bar that is fixedly connected to the corner joining part, and the second side frame portion includes two second bars connected to a middle joining part, one of the two second bars being fixedly connected to the coupling part.

7. The playpen according to claim 6 , wherein the two sidewalls of the corner joining part extend downward from the first bar, and the first locking mechanism includes a first latch that is at least partially received in the cavity between the two sidewalls of the corner joining part.

8. The playpen according to claim 7 , wherein the first latch is coupled to the standing leg, and is movable along with the standing leg as the standing leg rotates relative to the corner joining part.

9. The playpen according to claim 6 , wherein the second locking mechanism is assembled with the middle joining part.

10. The playpen according to claim 9 , wherein the second locking mechanism includes a second latch movably connected to the middle joining part, the second latch being movable relative to the middle joining part to engage with and disengage from the two second bars.

11. The playpen according to claim 10 , wherein the two second bars are respectively connected pivotally to the middle joining part about two second pivot axes, and the second latch has a locking portion disposed in a gap between the two second pivot axes.

12. The playpen according to claim 11 , wherein each of the two second bars has an end coupling part provided with an extension in the gap between the two second pivot axes, the locking portion of the second latch being movable in the gap to engage with and disengage from the extension of the end coupling part of each of the two second bars.

13. The playpen according to claim 10 , wherein the second locking mechanism further includes a spring connected to the second latch, the spring being configured to bias the second latch for engagement with the two second bars.

14. A playpen comprising:
an upper frame assembly coupled to at least one standing leg and having an unfolded state and a folded state, the upper frame assembly having a side frame portion including two bars that are respectively connected pivotally to 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 including a latch movably connected to the middle joining part;
wherein the latch is movable relative to the middle joining part 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 for rotation of the two bars, the latch being held with the middle joining part and configured to move along with the middle joining part relative to the two bars as the two bars rotate between the unfolded state and the folded state.

15. The playpen according to claim 14 , 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.

16. The playpen according to claim 14 , wherein the locking mechanism further includes a spring connected to the latch, the spring being configured to bias the latch for engagement with the two bars.

17. The playpen according to claim 14 , wherein the latch is movable vertically to engage with and disengage from the extension of the end coupling part of each of the two bars.

18. The playpen according to claim 14 , wherein the middle joining part includes a housing, and the latch has an actuating portion exposed through the housing for operation, the actuating portion being operable to cause the latch to move from the locking position to the unlocking position.

19. The playpen according to claim 18 , wherein the actuating portion is movable along with the middle joining part relative to the two bars when the upper frame assembly moves between the unfolded state and the folded state.

20. The playpen according to claim 18 , wherein the actuating portion is formed integrally with the latch.
