ABSTRACT:
A security locking assembly comprises a face plate locatable upon a dead bolt lock having a turn knob and a C-shaped component. The face plate has first and second apertures extending through it above and below the turn knob. A planar member with a circular hole is affixed to the face plate and extends within the dead bolt lock opposite from the turn knob. The C-shaped component includes a first horizontal bar, a second horizontal bar and a vertical bar. Each horizontal bar has an inboard end and an outboard end. The vertical bar includes an upper end, a lower end and a center point. The first and second horizontal bars are pivotally coupled in a generally perpendicular orientation to the upper and lower ends of the vertical bar, respectively. The vertical bar is pivotally coupled to the planar member by a hinge pin coupled through the aligned central hole of the vertical bar and circular hole of the planar member. The outboard extent of the first and second horizontal bars extend through the apertures of the face plate adjacent to the turn knob.
