Collapsible stroller

摘要

A collapsible stroller comprises a single front wheel and a front wheel support mounting the front wheel for rotation on an axis extending transversely with respect to the stroller. Two generally horizontal side frame members extend in a generally rearward direction from the front wheel support. Each side member has a forward end pivotally connected to the front wheel support for pivoting about a generally vertical axis. Two rear wheels are each rotatably mounted on a respective side frame member adjacent its rearward end. A collapsible rear frame member extends between the side frame members generally between the rear wheels. An upper frame extends up from the side frame members for supporting a child seat and a child therein. A handle is attached to the upper frame. The rear frame member is lockable in an uncollapsed condition for holding the side frame members in a diverging relationship in which they diverge rearwardly from the front wheel support. The rear frame member is movable from the uncollapsed condition to a collapsed condition to permit the side frame members to be pivoted about their respective vertical axes.
