ABSTRACT:
A passive air, gas aerosol or pressurized fluid activated personal self-protection screech alarm device that is armed prior to the person utilizing it entering into a potentially dangerous area or situation. The primary and radically different feature of this device from those currently patented and/or on the market is that no action is demanded of the person carrying it in the event of an attack other than the natural inclination to release ones grip. Releasing ones grip on the aerosol can and lever and dropping the device then activates an irrevocable screech alarm. This device plays to the psychological implications of attack in that if active, overt action is taken by the person who is the subject of a rape, for example, the attacker oftentimes becomes more violent. With this device, the natural inclination to show fright and drop whatever one is carrying serves to activate the alarm. More particularly, when the device is released from the hand, a spring loaded lever (similar in feature to a military hand grenade) flies up and away from the can and becomes separated. That in turn releases a spring loaded fly-away plug valve allowing the propellant to escape and sound the alarm signaling portion of the device.
