ABSTRACT:
The carriage has a pair of elongated handles each having an upper sleeve slidable therealong and each having an elongated front leg of the carriage secured to the sleeve. A pair of rear legs have their upper ends pivotally connected to respective front legs intermediate the ends of the latter, and each leg has a support wheel rotatably mounted on its lower end. Respective lower sleeves are slidable along the lower portions of each front leg. A pair of elongated frame members have their lower ends pivotally connected to respective front legs, and straps are secured to the upper end of each frame member, and each strap is formed with spaced apertures therealong and extends through a slot in one of the upper sleeves. The seat back of a carriage seat is secured to its side edges to these frame members and is foldable about a longitudinal center line. By virtue of the apertured straps sliding in the slots of the upper sleeve members, the seat back can be inclined at any selected angles relative to the handles. Spring biased hook means are provided to latch the seat back in adjusted position. An X-frame is formed by a pair of arms pivotally interconnected intermediate their ends, and each arm has its upper end pivotally connected to a respective lower sleeve. Tie rods are connected to the upper ends of the arms, and are interconnected to an operating knob. By upward or downward movement of the operating knob, the X-frame can be contracted or expanded to selectively collapse or erect the carriage.
