Abstract
A locking mechanism for locking two foldable sections (2a, 2b) of a grip rod (2) of a baby carriage has two gears (26) meshing with each other. The grip rod sections are foldably interconnected by a coupling (12) which supports the gears (26) for rotation around their respective axes. One end surface of each gear (26) is formed with a locking recess (29) for receiving a locking plate (20) in the locked state. The locking plate is movable axially of the gears (26) for unlocking. The locking plate (20) is urged by a spring (32) into the locking recesses (29) to maintain the locked state. A push button (23) moves the locking plate (20) out of the locking recesses (29) against the force of the spring (32) to permit the folding.
