1. The child safety barrier which comprises:
a U-shaped frame which defines an opening between first and second vertical columns, and
a door which is pivotally connected to said U-shaped frame to open and close said opening, said door including a vertical post that, when the door closes said opening, is positioned adjacent said second vertical column, and mounts a locking pawl which is movable towards and away from the second vertical column,
said second vertical column defining a groove and containing a third column which is slidable therein, said third column mounting a lock housing which extends through said groove towards said opening and which includes a channel having an inclined wall and a magnet at a bottom thereof, the locking pawl being positionable within the channel by attraction of said magnet to lock the door in a closed position relative to the U-shaped frame,
a push-pull rod connected to said third column, and
an activation device connected to said push-pull rod to move said third column within said second column and said lock housing along said groove to move said locking pawl along said inclined wall and away from said magnet to unlock the door relative to the U-shaped frame after receiving a signal from a signal generator.
