A child seat is detachably mounted on a foldable stroller comprising a stroller handle and front and rear leg portions. The stroller handle is foldably connected to the rear leg portion. The front leg portion is foldably connected to the rear leg portion and has a first adaptor. The child seat includes a first pivot and a seat frame having a lower seat portion and an upper seat portion foldably connected to the lower seat portion. The first pivot is pivotably connected to the lower seat portion and detachably mounted on the first adaptor. When the front leg portion and the stroller handle are folded relative to the rear leg portion, the upper seat portion is folded on the lower seat portion, and the lower seat portion is folded on the front leg portion via the first pivot together with the upper seat portion.

A child seat detachably installable on a child stroller apparatus includes a seat frame including a first and a second frame portion rotatable relative to each other for unfolding and collapsing the child seat, a side coupling part fixedly connected with the first frame portion and pivotally connected with the second frame portion, a tray connected pivotally with the side coupling part, a tray latch assembled with the side coupling part and operable to engage with the tray for locking the tray in a deployed position for use, and a linking member operatively connected with the tray latch and the second frame portion. A rotation of the second frame portion for collapsing the child seat causes the linking member to move for urging the tray latch to disengage from the tray.

A foldable push chair comprises a central chassis assembly defining a central axis extending substantially perpendicularly to a normal direction of travel of the push chair, the push chair has at least three wheel supporting legs extending from the central chassis and rotatable about the central axis between a folded and unfolded state, in the unfolded state at least one wheel supporting leg extending in a forward direction and at least one wheel supporting leg extending in a rearward direction, the forwardly and rearwardly extending wheel supporting legs being coupled together such that they rotate in opposite directions around the central axis during a folding or unfolding operation, latching means engagable with at least one wheel supporting leg and the central chassis or handle assembly for ensuring the push chair can be latched in either or both of an unfolded state or a folded state, energy storage means associated with at least one wheel supporting leg and the central chassis or handle assembly, configurable to be loaded with energy either: a) when the push chair is changed from a folded state to an unfolded state, or b) when the push chair is changed from a unfolded state to a folded state; when the energy storage means is at least partially loaded with energy at least some of the energy stored in the energy storage means being used to assist in either: a) folding the push chair, or b) unfolding the push chair respectively when the latching mechanism is released.

Strollers with removable seats and related methods are disclosed herein. An example stroller includes a wheeled frame, a receiver coupled to the frame, and a seat. The seat includes a hub, a mount, and a lock disposed in the mount. The lock is to move from a first positon to a second position when the mount is disposed in the receiver to removably couple the seat to the frame. The seat includes a handle and a pin disposed between the handle and the hub. The handle is moveable from a retracted position to an extended position when the pin is in a third position relative to the handle and the lock is to move from the second position to the first position when the handle moves from the retracted position to the extended position.

A child stroller apparatus includes a first and a second leg portion, a handle frame, a child seat slidably assembled with the first leg portion, and a linkage. The handle frame has a side segment that is respectively connected pivotally with the first leg portion via a first pivot connection and with the second leg portion via a second pivot connection, the first pivot connection and the second pivot connection respectively defining a first pivot axis and a second pivot axis spaced apart from each other about which the first leg portion and the second leg portion are respectively rotatable relative to the side segment of the handle frame. The linkage is respectively connected with the side segment and the child seat, whereby a sliding movement of the child seat along the first leg portion is linked to a rotation of the handle frame relative to the first leg portion.

Foldable strollers with removable seats and related methods are disclosed herein. An example stroller disclosed herein a wheeled frame, a receiver coupled to the frame, and a seat. The seat includes a mount, a lock disposed in the mount; and a handle having an extended positon and a retracted position relative to the seat. The lock is to move from a first position to a second position when the mount is disposed in the receiver to removably couple the seat to the frame, and the lock to move from the second position to the first position to release the seat from the receiver when the handle moves from the retracted position to the extended position.

The application discloses a frame of double-person baby carriage and a frame folding mechanism thereof. The frame folding mechanism comprises an upper link, a lower link, a middle upright rod, two upper supporting rods, two lower supporting rods and two foot frames. The upper link and the lower link are spaced apart in a vertical direction; the middle upright rod is vertically connected between the upper link and the lower link; first ends of the two upper supporting rods are pivotally connected to both ends of the upper link; first ends of the two lower supporting rods are pivotally connected to both ends of the lower link; the foot frames are arranged in a vertical direction, top ends of the foot frames are pivotally connected to second ends of the upper supporting rods, bottom ends of the foot frames are pivotally connected to second ends of the lower supporting rods.

A child transport carrier includes a lower frame, an upper frame, a rear frame, and a first upper seat support. The lower frame includes a first end and a second end. The upper frame includes a first end and a second end. The rear frame extends from the second end of the lower frame to the second end of the upper frame. The first upper seat support includes a cross-member extending transversely across the first upper seat support and having a first end and a second end. The cross-member is configured to move the first upper seat support between a first seat position and a second seat position. The upper frame extends from an upper end of the rear frame and the lower frame extends from a lower end of the rear frame.

A wheeled carrying apparatus includes a standing frame, a handle frame, a wheel mount, a locking assembly and a release mechanism. The handle frame is rotatable between a first and a second position. The wheel mount carries a wheel and is rotatable relative to the standing frame for changing an orientation of the wheel axis. The locking assembly is configured to rotationally lock the wheel mount with respect to the standing frame, and configured to unlock the wheel mount so that the wheel mount is rotatable relative to the standing frame for changing an orientation of the wheel axis. The release mechanism includes a first portion provided on the standing frame and coupled to the locking mechanism, and a second portion carried with the handle frame, the second portion being movable along with the handle frame toward and away from the first portion during rotation of the handle frame between the first position and the second position.
