The folding mechanism includes an intermediate component and a pair of connecting components. The intermediate component includes a tubular casing, a press block, and an unlocking piece. A rear part of the press block passes through a front surface of the casing to extend into the casing, and is movable back and forth. The connecting component includes a tubular housing and an engaging piece. The engaging piece is slidably mounted in the housing. In a locked state, a front end of the engaging piece penetrates into the casing. The unlocking piece has a fixing part, and the fixing part is disposed with a free end extending between a rear end of the press block and the front end of the engaging piece.

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 foldable push chair comprises a central body portion extending across the push chair and defining a central axis, the central axis extending substantially perpendicularly to the normal direction of travel of the push chair, a handle assembly connected to the central body and extending therefrom, at least three wheel supporting legs are rotatable around the central axis and extending from the central body, in the unfolded state one or more wheel supporting legs extend in a forward direction from the central axis and one or more wheel supporting legs extend in a rearward direction from the central axis; the forward and rearward extending legs are coupled together such that they rotate in opposite directions around the central axis during a folding or unfolding operation.

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.
