ABSTRACT:
An anti-vandalism lock device particularly adaptable for panic-type doors includes a substantially C-shaped housing having a substantially vertically disposed threaded bolt secured therein. The housing is adapted to be mounted upon one of the pivotable lever arms supporting the panic bar and connected with the panic door latching mechanism in such a manner that an end wall of the housing abuts one side surface of the lever arm while upper and lower laterally projecting sections of the housing similarly engage the upper and lower surfaces of the arm, and the threaded bolt is secured within the housing in such a manner as to engage the opposite side surface of the lever arm thereby fixedly securing the device upon the panic-bar assembly and positively preventing actuation of the door latching mechanism.
