ABSTRACT:
The present invention relates to a safety hinge mechanism for foldable play yard and that is used to pivotally connect a first frame rod and a second frame rod thereof. The connecting bracket can be selectively rotated along the longitudinal axis of the frame rod into a locking position, or a neutralized position. A locking device is provided and disposed onto any one of the first and second frame rods. The locking device can be moved along the longitudinal direction into a locked position, or a released position. Wherein in the locked position, the locking device is engaged with the connecting bracket and the connecting bracket is prevented from any rotational movement thereof. As a result, the first and second frame rods are allowed to fully extend while they are not allowed to fold together. However, when the locking device and the connecting bracket are disengaged, the connecting bracket is rotated to a neutralized position and the first and second frame rods can be folded in a side-by-side manner. By the provision of the locking device, the hinge mechanism can be readily locked and the possibility of being incidentally released during the usage can be therefore prevented. A durable hinge mechanism for foldable play yard is therefore provided.
