ABSTRACT:
A gate locking device for a fence which includes a security box having a mounting plate affixed within the box. The security box is mounted to a pole of the fence. An oarlock is hingeably mounted within the security box. The oarlock is capable of movement between an unlocked position and a locked position. In the locked position the oarlock engages another pole of the fence. A dead bolt is securely affixed to the mounting plate within the security box and is movable between an extended and unextended position. The dead bolt is disposed in mechanical relation to the heel plate of the oarlock so that when the dead bolt is moved to the extended position it substantially prevents the pivotal movement of the oarlock. A barrel lock is mounted to the security box and mechanically connected and adapted to the dead bolt for moving it between the extended and unextended position. When the oarlock is moved to the locked position and the dead bolt is moved to the extended position the oarlock can not be moved back to the unlocked position and the gate is securely locked to prevent unauthorized intrusion.
