Abstract: A foldable crib includes a side rail and an underframe. The side rail includes foldable horizontal bars. The foldable horizontal bar includes a first locking mechanism and a movable unlocking member. The movable unlocking member has a first unlocking stroke for unlocking the first locking mechanism. The underframe includes a lifting and flipping mechanism. The lifting and flipping mechanism includes a second locking mechanism and a handle. The handle has a second unlocking stroke for unlocking the second locking mechanism. The handle is linked with the movable unlocking member through a first linkage structure such that the second unlocking stroke of the handle is capable of causing the first unlocking stroke of the movable unlocking member. A second linkage structure is configured to link the foldable horizontal bar to be unfolded when the underframe is unfolded.

Abstract: Embodiments provides a side structure of a fence frame, a fence frame, and a folding method. In the embodiments, the side structure includes two vertical struts, between which is provided: two upper rods provided horizontally, adjacent ends of them can be connected relatively rotatably, and remote ends of them are respectively detachably provided above the two vertical struts, the two upper rods are rotated downward to approach each other after disassembly; two lower rods provided horizontally provided, adjacent ends of them can be connected relatively rotatably, remote ends of them are rotated downward relative to the lower ends of the two vertical struts to approach each other; two diagonal struts, adjacent ends of them are rotatably connected to the intersection of the two upper rods, and remote ends of them can rotate upward relative to the lower ends of the vertical struts to approach each other.
