ABSTRACT:
A child safety latch which cannot be actuated by those having relatively short fingers. A spring-biased lock is slidably moved within the J-shaped tracks of a guard tube. The latch is in an unlocked position when the locking pin rests in the larger side of the J-shaped track. In this position, the spring biases the locking pin against the top of the larger side of the track. Actuation of the latch, i.e. pushing down on the button located on top of the lock, lowers the lock against the spring. The complete lowering of the lock and the full compression of the spring occurs when the locking pin is at the bottom of the J-shaped track. A slight counter-clockwise twist of the finger urges the locking pin into the smaller side of the J-shaped track, where the lock is spring biased against the top of the smaller side. Thus, the lock is in a locked position and can only be opened by someone having fingers long enough to reach into the tube and to disengage the lock, by depressing the actuation means and rotating it in a clockwise direction.
