A stroller has a first frame part and a second frame part capable of movement between at least two positions relative to the first frame part. A push-pull mechanism has a push-pull element that directly or indirectly connects the first and second frame parts. Moving the first frame part causes the push-pull mechanism to move the second frame part. The mechanism can be employed on the stroller frame to assist in folding and/or unfolding the stroller. |
