Abstract

A collapsible device for a baby carriage has a locking disc as a male joint fixed with an inverted U-shaped push rod and a female joint fixed with each of the ends of a protective rod combined together and locked or unlocked by a push button fitted in the female joint. A locking block deposited and moved back and forth in a chamber in the female joint to engage or disengage from the locking disc so that the female joint can be locked together or unlocked from the locking disc so as to swing up the protective rod relative to the push rod for collapsing the baby carriage.
