Described embodiments include a stroller with one or more first wheels, one or more first wheel support structures for supporting the one or more first wheels which are moveable from a collapsed position to an open position, with the stroller also having one or more second wheels, one or more second wheel support structures for supporting the one or more second wheels moveable from a collapsed to an open position, and one or more drive mechanisms operatively engaged with at least one of the one or more first wheel support structures and at least one of the one or more second wheel support structures to move the at least one of the one or more first wheel support structures from its collapsed to its open position, and the at least one of the one or more second wheel support structures from its collapsed to its open position.
Problems solved by technology
However, current strollers do not allow for movement or folding to as compact of a configuration as desired, and are cumbersome and sometimes difficult to move between their collapsed (closed) position and their open (operative) positions, particularly when attending to a baby or child.
