ABSTRACT:
A foldable baby stroller having left and right side front wheel supports with a front wheel mounted to a forward end, and a laterally extending rear axle with a rear wheel mounted to each end. The stroller has left and right side rear wheel supports, each with a lower end attached to the rear axle; and left and right side handle supports with a handle spanning between them. The stroller has left and right side folding assemblies, each having a pair of mounting plates and a guide pivotally attached therebetween. Each folding assembly has a rearward end of one of the front wheel supports fixedly attached between the plates. A forward end of one of the handle supports is pivotally attached between the plates and rotatable relative to the front wheel support. An upper end portion of one of the rear wheel supports is positioned between the plates with an upper end being pivotally attached to the forward end of the corresponding handle support for application of a drive force thereto by the handle support. The guide has an aperture with one of the rear wheel supports slidably disposed therein. The guide and guide aperture are configured to rotate the rear wheel support and to also slide the rear wheel support in the guide aperture in response to rotation of the corresponding handle support. Alternative style guides can also be used.
