Title:
COOL BOX WITH ALARM
Document Type and Number:
Japanese Patent JP2011246905
Kind Code:
A
Abstract:

To increase a deterrent effect of theft of stored objects in a cool box having a locking device.

A locking device 5 is provided in a door 2 of the cool box, and locking and unlocking of the locking device 5 and an operation switch 6 (a key switch) are interlocked. When the locking device 5 is in a locked state, the operation switch 6 shifts into on-state, and if the door 2 is opened in this state, a door switch 10 shifts into on-state. Then, a circuit consisting of a main power supply 11, the operation switch 6, the door switch 10 and an alarm 7 (an alarm buzzer) turns to a closed circuit, and the alarm 7 operates by being supplied electricity by the main power supply 11. On the other hand, when the locking device 5 is in an unlocked state, the operation switch 6 shifts into off-state and the circuit turns to an open circuit, and the alarm 7 does not operate regardless of whether the state of the door 2 is opened or closed. Since the main power supply 11 is provided with an auxiliary power supply 12 and electricity is supplied by the auxiliary power supply 12 when the main power supply 11 fails, reliability of crime prevention is high.
