US 2003/0155745 A1 · Foldable infant jogging stroller

Abstract

A three-wheeled jogging stroller with a collapsible frame assembly. The frame assembly includes a primary structural rear axle assembly having a member of an enlarged diameter tubular construction with couplers at opposite ends thereof for supporting large diameter spoked wheel pneumatic tires. The rear axle assembly has fixedly coupled thereto a pair of upright support members and a fork assembly. A pair of generally parallel fork members support the front wheel at one end thereof, while at the other end, the fork members are pivotally coupled to the rear axle member by means so that the pivotable coupling is displaced, or offset, a given distance from the axis of the rear axle member so that, on folding, the fork and the upright support members are generally parallel to one another. The handlebar assembly includes a first generally U-shaped handlebar member and a second tubular portion including first and second tubes having first ends thereof fixedly coupled to an interconnect member to which is pivotally coupled the upright support members. Third and fourth frame tubes are attached at the forward end of the fork, the other ends are slidably received through the interconnect member. The interconnect member and the respective third or fourth tube have cooperative hold and release means for either locking said interconnect to said tube, to maintain the stroller in an erect position, or for releasing said interconnect to allow it to slide down the tube to fold the stroller into a collapsed position.

Dependent claims

A foldable stroller for use while walking or running, said stroller comprising:

a rear axle assembly;
three wheels;
a pair of upright support tubes having first ends thereof fixedly coupled to said axle assembly in proximate relation to the ends thereof;
a base fork assembly having first tube ends thereof pivotally coupled to said rear axle assembly proximate the center thereof in general parallel relation;
coupling means, affixed at the other tube ends of said fork assembly, configured for supporting a third of said wheels;
an upper frame assembly including generally U-shaped handlebar member configured for gripping by the user;
first and second handlebar tubes;
first and second hinges pivotally coupling free ends of said U-shaped handlebar to a first ends of said first and second handlebar tubes;
third and fourth tubes having first ends pivotally coupled to said coupling means at said other ends of said fork assembly;
and first and second generally identically configured interconnect members, each of said interconnect members including
a) means for fixedly securing the other end of one of said first and second handlebar
b) means for pivotally coupling thereto the free end of one of said upright support tubes;
and
c) means for slidably receiving therethrough the free end of one of said third and fourth tubes at a position which enables said interconnect member to slide freely along said one of said third and fourth tubes to thereby enable said upper frame assembly to fold from an erect position into a collapsed position overlying said base fork assembly.
