A stroller frame including a bottom member 40, a handle 20, a supporting component 30, a linking assembly 50, a front leg 10 with a front wheel assembly (122, Fig.7), and a rear leg 60 with a rear wheel assembly (62). The front leg is pivoted to the bottom member at a first point A1 and to the handle at a second point A2. The supporting component is pivoted to the handle at a third point A3, to the bottom member at a fourth point A4, and to the linking assembly at a fifth point A5. The rear leg is pivoted to the linking assembly at a sixth point A6 and to the bottom member at a seventh point A7. A first four-bar mechanism including the first to the fourth points is linked with a second four-bar linkage mechanism including the fourth to the seventh points for folding or unfolding the front and the rear wheel assembly when the stroller frame is folded or unfolded. The linking assembly may be sprung and comprise a first and second connecting component (52, 54, Fig. 5). A locking member may be provided between the front leg and handle to maintain the frame in an unfolded state. |
