a first housing mounted to the exterior surface of said door with an opening in a side of the first housing that is adapted and arranged for receiving a lock bolt;
a second housing enclosing a lock for actuating a lock bolt adapted and arranged for being received by the opening in the side of the first housing when the door is closed;
a blocking means coupled to a side of the second housing and positioned substantially horizontally above and below the lock bolt for blocking access to the lock bolt from above the lock bolt and below the lock bolt and is located between the first housing and second housing; and,
a receiving means recessed in the first housing for receiving the blocking means wherein the receiving means is positioned adjacent the lock bolt opening and blocks access to the lock bolt.
2. The apparatus of claim 1 further comprising:
the first housing has a first wall including a first stop surface disposed external to the cell and the door opening and overlapping a portion of the second housing; and,
the second housing has a second wall including a second stop surface conformed to abut against the first stop surface when the cell door is closed.
3. The apparatus of claim 1 wherein the blocking means comprises a protruding strip.
4. The apparatus of claim 3 wherein the protruding strip has either a smooth edge, a saw-tooth edge, or a square tooth edge.
5. The apparatus of claim 1 wherein the receiving means comprises a recess in the first housing for receiving the blocking means within the recess.
6. An apparatus for mounting and supporting a locking mechanism for locking a detention cell door having a surface exterior to the cell and supported within a door opening defined in a cell wall, said cell wall also having a surface exterior to the cell, said apparatus comprising:
a first housing mounted to the exterior surface of said door with an opening in a side of the first housing that is adapted an arranged for receiving a lock bolt;
a second housing enclosing a lock for actuating a lock bolt adapted and arranged for being received by the opening in the side of the first housing adjacent to the lock bolt when the door is closed;
a strip protruding from the second housing and positioned substantially horizontally above and below the lock bolt for blocking access to the lock bolt and located between the first housing and second housing; and,
a recess positioned adjacent the lock bolt opening between the first housing and the second housing that is recessed in the first housing for receiving the strip and blocking access to the lock bolt.
7. The apparatus of claim 6 further comprising:
the first housing has a first wall including a first stop surface disposed external to the cell and the door opening and overlapping a portion of the second housing; and,
the second housing has a second wall including a second stop surface conformed to abut against the first stop surface when the cell door is closed.
8. The apparatus of claim 6 wherein the strip has either a smooth edge, a saw-tooth edge, or a square tooth edge.
9. A detention cell door locking apparatus comprising:
a first housing with an opening on the side of the first housing adapted an arranged for receiving a lock bolt;
