MECCANISMO DI BLOCCAGGIO PER LA BARRA D'IMPUGNATURA DI UNA CARROZZINA PER NEONATI.

摘要

A locking mechanism for a divided grip rod of a foldable baby carriage permits automatically locking the grip rod in an unfolded state and this locking can be canceled by a simple operation. The grip rod (2) is divided into two portions (2a, 2b), which are interconnected at their ends while being supported for rotation around the axes of parallel rotary shafts (6). Lateral surfaces of the ends of the portions of the grip rod intersect the rotary shafts. Each lateral surface has a locking recess (12). A locking plate (4) is movable axially of the rotary shafts so that it can fit simultaneously in the two locking recesses when the grip rod is in its straight state. The locking plate is urged by a spring in the direction in which it fits in the locking recesses for normally maintaining the locked state. An unlocking member (5) is provided to for disengaging the locking plate from the locking recesses against the force of the spring to permit folding of the grip rod.
