JOGGING STROLLER FRAME WITH A FRONT WHEEL AUTOMATIC FLATTENING FOLDING MECHANISM

摘要

A jogging stroller frame with a front wheel automatic flattening folding mechanism is provided with a jogging stroller frame which can be folded into a substantially flattened configuration for compact storage by an associating of a linking rod. When the foldable jogging stroller frame is folded into the substantially flattened configuration, the seat support rack shall pull the front wheel set to rotate backward about a horizontal axis to the pair of rear struts through the linking rod, thereby converting the foldable jogging stroller frame into a successively smaller size for more compact storage.
