  • Publication number: 20240016310
    Abstract: A foldable mechanism is applied to locking an infant carrier and includes first and second mounts and a locking member. The second mount is pivoted to the first mount and has first and second mating portions. The locking member is movably disposed between the first and second mounts and is movable along an axial direction of a rotating axis of the first and second mounts to lock and release rotation of the first mount. The locking member has a positioning portion and a locking portion. The first mount is locked at a first rotating position or a second rotating position via movement of the locking member. The positioning portion is engaged with the first mating portion to lock the first mount at the first rotating position. The locking portion is engaged with the second mating portion to lock the first mount at the second rotating position.

  • Patent number: 11805920
    Abstract: A foldable mechanism is applied to locking an infant carrier and includes first and second mounts and a locking member. The second mount is pivoted to the first mount and has first and second mating portions. The infant carrier is locked in the folded state when the first mount rotates to a first rotating position, and is locked in the expanded state when the first mount rotates to a second rotating position. The locking member is movably disposed between the first and second mounts and has a positioning portion and a locking portion. The positioning portion is engaged with the first mating portion to lock the first mount at the first rotating position. The locking portion is engaged with the second mating portion to lock the first mount at the second rotating position. A depth of the first mating portion is shallower than a depth of the second mating portion.

  • Patent number: 11484129
    Abstract: The present invention discloses a foldable mechanism and an infant carrier thereof. The foldable mechanism includes a first mount, a second mount and a locking member movably disposed between the first mount and the second mount. The first mount is pivotally connected to the second mount. The infant carrier is locked in the folded state when the first mount rotates to a first rotating position relative to the second mount. The infant carrier is locked in the expanded state when the first mount rotates to a second rotating position relative to the second mount. The first mount is locked at the first rotating position or the second rotating position via movement of the locking member, so as to make the foldable mechanism have a simple folding mechanical design and improve folding stability of the foldable mechanism.
