Abstract (en)
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 (67) of the enclosure have apertures or projections (69) which interlock with mating projections or apertures (73, 75) 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.
