Abstract

A foldable push chair having two side frames, each side frame having a forward strut and a rear strut attached at its uppermost end to the forward strut, and a base strut linking the rear and forward struts, wherein the forward strut has an upper section and a lower section, pivotally connected by a connection. The connection allows the upper section and lower section to pivot relative to each other, between a folded state and an unfolded state, the upper and lower sections being parallel and co-linear when the push chair is in the unfolded state.
