Abstract

Abstract A detachable multi-purpose self-defending device and in particular to one mainly composed of a grip and a barrel, the grip being provided with a high voltage oscillating circuit for supplying a high voltage to the electrodes mounted at the front end of the barrel so as to be able to make the wicked faint temporarily, a pizo siren for sending out warning signal to arouse the other's attention to arrest the wicked, a flashlight for giving light in the dark, and a strobe light for emitting rapid, brief and brilliant flashes of light to cause the weaked to lose consciousness momentarily. Moreover, the grip may be connected to a leaf-spring switch which is inserted between the door and the frame so that when the door is opened, the spring leaves thereof will separate from each other hence actuating the pizo siren. In addition, the grip may be connected with a sensor which is designed so that in case the fume conncentration and the temperature exceed the rated value, the pizo siren will be actuated to send out a warning signal.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 175 words
A detachable multi-purpose self-defending device comprising: a grip provided with a plurality of slots formed within an inner surface thereof, a light switch for controlling a flashlight mounted on a top surface thereof, a strobe light switch for controlling a strobe light located beside the flashlight, and a pizo siren switch for controlling a pizo siren located on one side of said grip, a detachable hook member located on an opposing side of said grip for releasably mounting said self-defending device to a user's clothing ; and a barrel having a front end, two electrodes mounted on said front end of said barrel defining a pair of electrical discharging components, a switch connecting said electrodes with a high voltage oscillating circuit disposed in the barrel for passing a high voltage electrical charge to said electrodes and a plurality of protruding members adapted to engage with corresponding slots of the grip for releasably coupling said barrel to said grip, said grip including a room for receiving a battery electrically coupled to said high voltage oscillating circuit.
Claim 2
Dependent Claim 175 words
A detachable multi-purpose self-defending device comprising: a grip provided with a plurality of slots formed within an inner surface thereof, a light switch for controlling a flashlight mounted on a top surface thereof, a strobe light switch for controlling a strobe light located beside the flashlight, and a pizo siren switch for controlling a pizo siren located on one side of said grip, a detachable hook member located on an opposing side of said grip for releasably mounting said self-defending device to a user's clothing ; and a barrel having a front end, two electrodes mounted on said front end of said barrel defining a pair of electrical discharging components, a switch connecting said electrodes with a high voltage oscillating circuit disposed in the barrel for passing a high voltage electrical charge to said electrodes and a plurality of protruding members adapted to engage with corresponding slots of the grip for releasably coupling said barrel to said grip, said grip including a room for receiving a battery electrically coupled to said high voltage oscillating circuit.
Claim 3
Dependent Claim 85 words
A detachable multi-purpose self-defending device as claimed in claim 1, wherein said grip is further provided with a socket connecting said pizo siren to a leaf-spring switch and a sensor, said leaf spring switch coupled to said pizo siren including a pair of leaf springs which may be inserted between a door and a frame member in contiguous contact each with respect to the other, when said door is opened, said leaf springs being separated for actuating said pizo siren to emit a warning signal.
