ABSTRACT:
A portable, auxiliary lock assembly of the type used to secure the conventional or permanently installed lock bolt in its locked position thereby preventing inadvertent admittance through the use of a key or through unauthorized manipulation of the lock mechanism itself. A pair of clamp arms are spaced between the door frame and the edge of the door containing the locking assembly and disposed into firm grasping engagement with the portions of the lock bolt when it is in its locked position. Movement of the lock bolt into its unlocked position is thereby prevented until such bolt is released by the clamp arms of the auxiliary lock assembly.
