Abstract
A locking device for securing to a door or the like and including a rotatable knob adapted for mounting at a front surface of the door and having locked and unlocked positions, a locking member adapted for positioning at an opposite rear surface of the door and in alignment with the rotatable knob and a key-controlled lock supported at the front surface of the door and having locked and unlocked positions. The locking member includes a locking bar and an integral latch plate having a free end. The locking bar is for engagement with a door striker in the locked position. The key-controlled lock is spacedly disposed from the locking member and adapted for engaging, inside the door, with the free end of the latch plate. The key-controlled lock, in its locked position, engages with the latch plate to prevent rotation of the rotatable knob, and in its unlocked position, disengages from the latch plate to enable rotation of the rotatable knob from its locked position to its unlocked position.
