10696316 · 2020-06-30 ·

The stair-climbing stroller is a baby stroller with retractable front and rear wheels for use on flat travel surfaces and a pair of tracks for use on inclined travel surfaces including, but not limited to, staircases. The front wheels are coupled to a pivoting front wheel support shaft and the rear wheels are coupled to a pivoting rear wheel support shaft. A wheel retract motor located on the underside of the stroller may cause a retraction drive shaft to pivot the front and rear wheel support shafts, retracting the wheels. When the front and rear wheels retract, the stroller may be lowered such that the left and right track rest on the ground. Left and right track motors may then be used to drive the stroller up an inclined travel surface using the tracks.
