ABSTRACT:
A stroller includes a pair of side frames, each including a main side tube comprised of upper and lower tube portions pivotally mounted to each other, a rear side tube pivotally connected to the upper tube portion, and a support rod pivotally connected to the rear side tube and to the lower tube portion; a rear articulated spreader bar mechanism for connecting together the rear side tubes of the pair of side frames, the rear articulated spreader bar mechanism including a pair of rear pivoting spreader bars, each pivotally connected at one end thereof to a respective rear side tube and at an opposite end thereof to the other rear pivoting spreader bar; a front articulated spreader bar mechanism for connecting together the lower tube portions of the pair of side frames, the front articulated spreader bar mechanism including a pair of front pivoting spreader bars, each pivotally connected at one end thereof to a respective lower tube portion and at an opposite end thereof to the other front pivoting spreader bar; and actuating rods connected between the support rods and each of the rear articulated spreader bar mechanisms and the front articulated spreader bar means, such that folding of the upper tube portions relative to the lower tube portions in a lengthwise direction of the stroller causes articulation of the front and rear articulated spreader bar mechanisms which results in widthwise contraction of the stroller.
