ABSTRACT:
An all-purpose/all-terrain tripodal stroller suitable for urban and rural or recreational and fitness related activities, including street strolling and shopping, or jogging and off-road hiking and strolling. An improved stroller chassis design with high ground clearance yet low center of gravity, maximizing collapsibility yet minimizing total size of vehicle envelope. When folding, the improved chassis allows the front wheel to pivot rearward until in alignment with both rear wheels, while the variable height steering handle folds down around central wheel. All pivot points engaged while collapsing are cantilevered out of plane with support members, which minimizes all scissoring and pinching actions between all framing members.
