ABSTRACT:
An operating mechanism disposed on a handle bar of a baby carriage for actuating locking mechanisms disposed at opposite ends of the handle bar and which locks the handle bar at a predetermined position or locks the baby carriage in a folded or an unfolded position. The handle bar has a hollow tubular construction and is bent in a U-shape or an inverted U-shape as viewed from its front. The operating mechanism includes a pair of slide members each of which is slidably disposed at the central portion of the handle bar, operating wires inserted into the handle bar, each of the operating wires having an upper end respectively retained by each of the slide members and a lower end attached to the locking mechanisms, and slide guide projections projecting from upper and lower sides of each of the slide members and an operating grip rotatably mounted on the surface of the handle bar, the operating grip having U-shaped guide grooves formed therein into which the slide guide projections are received. In this manner, the slide members can slide in the horizontal directions in the handle bar in response to rotation of the operating grips to thereby actuate the locking mechanisms.
