  • Patent number: 11400837
    Abstract: A handle adjusting mechanism for adjusting a handle relative to a carrier body pivotally connected to the handle, includes a locking component slidably disposed at a pivotal connection of the handle and the carrier body. The locking component includes a first locking portion and a second locking portion. The first locking portion is for engaging with the handle. The second locking portion is for engaging with the carrier body. The handle is restrained from pivoting relative to the carrier body when the locking component slides to an engaging position to engage the first locking portion with the handle and to engage the second locking portion with the carrier body. The handle is allowed to pivot relative to the carrier body when the locking component slides to a disengaging position to disengage the first locking portion from the handle and to disengage the second locking portion from the carrier body.

  • Patent number: 11155292
    Abstract: A safety lock includes a releasing component and a locking component. The locking component is movably disposed on a frame releasing component or a stroller frame. The locking component is driven by the releasing component to move relative to the frame releasing component or the stroller frame between a blocking position and a releasing position. The locking component engages with the frame releasing component to restrain the frame releasing component from unlocking the stroller frame or engages with the stroller frame to restrain the stroller frame from being folded when the locking component is located at the blocking position, and the locking component disengages from the frame releasing component to allow the frame releasing component to unlock the stroller frame or disengages from the stroller frame to allow the stroller frame to be folded when the locking component is located at the releasing position.

  • Patent number: 9743779
    Abstract: An infant chair apparatus includes a support base, a seat frame, a support base and a motion driving module. The seat frame is pivotally supported on the support base by an upright column, the seat frame being rotatable relative to the support base about a pivot axis, and the upright column including a column portion affixed with an underside of the seat frame. The motion driving module is attached with the support base, and includes a driving part that is arranged below the seat frame at a location offset from the pivot axis, the motion driving module being operable to cause reciprocated rotation of the driving part that imparts a substantially horizontal oscillating motion to the column portion and the seat frame.
