Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
An alarming wallet comprising: a wallet having two leaves foldable upon each other; and an alarming circuit including: an alarm switch having two contactors respectively formed on two outer surfaces of the two leaves of the wallet, a transistor connected to and actuated by said alarm switch, a sounding integrated circuit connected with a piezoelectric buzzer and connected to a power source through said transistor, whereby upon a withdrawal of said wallet from an owner's pocket, purse or handbag by a pickpocket, the pickpocket's fingers will touch said two contactors of said alarm switch to render said transistor conductive to trigger said sounding integrated circuit and said piezoelectric buzzer for alerting a possible theft of said wallet.
