  • Patent number: 12599249
    Abstract: An anti-rollover structure, applicable to the cot body, includes at least two fixing elements and at least two support elements. The fixing elements are adapted to be mounted on an outer bottom surface of the cot body. The support elements are rotatably disposed at the fixing elements respectively. When the support elements are on a support surface, the support elements are subjected to pressure from the cot body and thereby rotated to protrude protruded from the cot body. A carrying device and a baby carrier are further introduced. The carrying device and the baby carrier each have the anti-rollover structure.

  • Patent number: 12280816
    Abstract: A folding device of a stroller includes a folding assembly which is configured to fold the stroller and a safety assembly. The folding assembly includes an operable pull handle. The pull handle is slidably sleeved over a handle frame of the stroller and is movable between a holding position and a release position. The safety assembly is configured to cooperate with the folding assembly, in which the safety assembly includes a locking member for preventing misoperation of the pull handle, and the locking member is switchable between a locked position and an unlocked position. The locking member is configured to prevent the pull handle from moving to the release position responsive to the locking member being in the locked position; and the locking member is entirely located inside the handle frame responsive to the locking member being in the unlocked position.

  • Publication number: 20250042461
    Abstract: The disclosure provides an auxiliary mechanism for assisting folding or unfolding a frame of a pushcart as well as a pushcart. The frame includes a first rod and a second rod being pivotable relative to each other. When the first rod and the second rod are relatively pivoted to a first position, the frame is in an unfolded state; and when the first rod and the second rod are relatively pivoted to a second position, the frame is in a folded state, wherein the auxiliary mechanism includes an elastic member, the elastic member drives the first rod and the second rod to be relatively pivoted towards the first position or towards the second position. The auxiliary mechanism according to the disclosure facilitates the user to unfold or fold the frame more easily, and enables the frame to be unfolded or folded in place, thus avoiding potential safety hazards.
