Abstract
A portable door lock that includes a tension plate insertable into the clearance space between the edge of a door and the facing surface of a door jamb. Ears on the plate hook into a striker plate opening. A door keeper element is swingably connected to the tension plate for movement against the exposed face of the door. The door-engagement surface of the keeper element is a cam surface adapted to move angularly along the door face at a relatively slight angle, such that the keeper element assumes a wedged condition. The cam surface gives the keeper element an adjustability that compensates for tolerance variations in the spacing between the door face and the striker plate opening.
