ABSTRACT:
Luggage having alarm device to protect against robbery, burglary and being inadvertently left behind comprises, inside the luggage, an alarm and shocker assembly that includes a siren and circuitry with a transformer to produce a high voltage. Bare electrical wires are spread around the inner wall of the luggage. A remote controller that is capable of dispatching a coded signal is used to activate the circuitry to produce a high voltage electric shock and/or sound an alarm to prevent the luggage from being carried away or stolen. The alarm assembly may further include a signal transmitting circuit and a receiving circuit and a buzzer may be added to the remote controller carried by the luggage owner. The effective distance can be preset for the response of a signal so that when the luggage is in a position beyond said preset distance, the alarm is triggered to warn that the luggage is being burglarized or is being inadvertently left behind.
