Patent attributes
A stroller frame has a body, two front wheel assemblies, a seat supporting mechanism, and a rear wheel folding mechanism. The two front wheel assemblies are respectively and pivotally disposed on the body. The seat supporting mechanism is moveably disposed below a seat plate of the body. The rear wheel folding mechanism is disposed on a rear side of the body and has two rear wheel assemblies and two linkage assemblies. The two rear wheel assemblies are moveably disposed on a first transverse rod of the body. The two linkage assemblies are respectively disposed on two ends of a second transverse rod of the body. When the stroller frame is folded, two rear wheels of the two rear wheel assemblies move between two front wheels of the two front wheel assemblies to decrease the overall width and volume of the folded stroller frame.
