  • Patent number: 4706577
    Abstract: A lockable enclosure is disclosed which may be installed at locations accessible to customers for vending merchandise, dispensing money or receiving deposits, and where a potential attacker would have only a limited period of time to break into the enclosure before the police or security personnel would be able to arrive and intervene against the attacker. The latches and latch bolts of the enclosure have apertures or projections which interlock with mating projections or apertures upon deformation of the sheet metal door or the sheet metal walls of the enclosure when an attacker deforms the enclosure sufficiently to cause damage to the lock or latches. Such interlocking prevents retraction of the latches or latch bolts holding the door closed even if the lock mechanism is completely destroyed or removed by force.

  • Patent number: 4686912
    Abstract: The electronically controlled locking apparatus is used with a door such as a safe door, and enables the door to be released by either a mechanical combination lock or an electrical lock control circuit. The control circuit generates an output signal when a correct access code is entered by a user for causing a control linkage to release the door. Alternatively, the mechanical lock can also cause the control linkage to release the door by authorized personnel, in the event of either a control circuit malfunction, or the authorized user being unable to recall the access code. The circuit includes both a non-volatile and a volatile memory means for storing the access code, and a display device for providing a visual indication of the correct code within the protected area, so that the door can be unlocked with the mechanical lock, and then the access code for the electrical lock circuit can be viewed at the protected side of the door.
