ABSTRACT:
A locking/unlocking manipulation mechanism for locking and unlocking the locking device of a baby carriage which precludes the collapsing of the carriage. The locking/unlocking manipulation mechanism includes a housing, a pulley rotatably supported in the housing, a wire connected at one end to the pulley and at the other end to the locking device, a manipulation button including a drive plate extending vertically from the main body of the button into the housing and engaged with a portion of the pulley and a sliding prevention stopper slidably disposed in the upper portion of the housing. When the button is urged into the housing the drive plate causes the pulley to rotate to thereby tension the wire and unlock the locking device. The stopper includes a sliding prevention plate extending from the bottom thereof into the housing so that the tip of the prevention plate can selectively contact the drive plate to prevent the button from being moved.
