Abstract: A locking device for protecting the contents of a container from theft includes an extension member having an adjustable length and a lock for inhibiting adjustment of the extension member's length when the lock is engaged. To secure the contents of a container from theft, the locking device is installed between two opposing surfaces, such as between two vertical wall surfaces, with the extension member extending across the container door with the door in its closed position. The locking device is installed by simply inserting each end of the extension member into suitable cavities formed in the opposing surfaces, or in brackets attached to the opposing surfaces, adjusting the length of the extension member as necessary. Thereafter, the lock can be engaged to prevent adjustment of the extension member's length, and thereby prevent removal of the ends of the extension member from the surface openings.

The anchors are oriented so that the slot in each anchor aligns with the slot in the other anchor when the door is in a closed position and the apparatus is engaged. A cross bar is placed between the anchors to prevent the door from opening. The cross bar is connected to the anchor on the edge of the door which is on the same edge of the door as the hinge of the door by a pin which allows the cross bar to be rotated upwardly. The anchor with the hinge is connected to the floor in such a manner as to allow the anchor to rotate on an axis which is perpendicular to the floor.

Abstract: A security indicator has a two part telescopic locking bar attached to the handle of a door at one end and to the door or door jamb at the other end through an end piece. The device includes a cup or tube which encases the door handle, preventing use of the handle. The length of the bar is fixed by aligning apertures in each part of the telescopic locking bar to form a continuous aperture, inserting a frangible pin through the continuous aperture and locking the frangible pin in place with a padlock received by a hole in the frangible pin. The pin has a narrow portion which can be broken by relatively little human force. The device requires someone who does not have the key to the padlock on the frangible pin to break the frangible pin to enter a door fixed with the device. A broken pin alerts the occupant that an entry has occurred during his/her absence. A sleeve normally protects the narrow portion but slides easily away to expose the narrow portion when entry is desired.
