ABSTRACT:
A portable door locking apparatus for use in combination with a door frame supporting a door, the frame having a latch recess for engaging a latch on an edge of the door. A planar member has an inner end adapted to be located between the door frame and the edge of the door and a free end projecting laterally from the door when the inner end is disposed between the door frame and the edge of the door. A tab projecting from the planar member is located within the latch recess to connect the planar member to the door frame so that the inner end of the planar member is located between the door frame and the edge of the door. At least one slot is located within the free end of the planar member. The slot has an edge disposed substantially parallel to the edge of the door when the planar member is connected to the door frame. A bolt having one end with a substantially, at least partially annular groove engages the edge of the slot and is adapted to be received in the slot. When the planar member is located between the door frame and the edge of the door and the planar member is connected to the door frame by the tab located in the latch recess and the groove of the bolt engages the edges of the slot, the bolt precludes opening of the door.
