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.

An auxiliary lock assembly primarily designed to prevent longitudinal displacement of a conventional lock bolt element, said assembly comprising:
- frame means dimensioned and configured for placement between door edge and a door frame and including two clamp arms movably interconnected to one another, each clamp arm comprising grasping means formed on correspondingly positioned interior edge portion of each arm in spaced apart relation to one another, closing means interconnected to each clamp arm and disposed to position said clamp arms into and out of grasping engagement with oppositely disposed external surface portions of the lock bolt element, whereby movement of the lock bolt along its own longitudinal axis and into a non-locking position is prevented.
