Patent ID: 8690020

Claim:
A self-defense device comprising: a trigger with an ON state and an OFF state; an air horn, wherein the air horn produces a noise in response to the trigger being in the ON state; a self-defense aerosol spray unit, wherein the self-defense aerosol spray unit sprays a stream of self-defense aerosol in response to the trigger being in the ON state; and a coupling device, wherein the coupling device couples the air horn to the self defense aerosol spray unit, wherein the coupling device comprises a nozzle, a trigger guard, a coupling piece and a coupling piece cover; wherein the trigger comprises: a first trigger portion, wherein the first trigger portion places the self-defense aerosol spray unit in the ON state in response to the first trigger portion receiving pressure; a second trigger portion, wherein the second trigger portion places the air horn in the ON state in response to the first trigger portion receiving pressure; and a trigger portion coupler, wherein the trigger portion coupler mechanically couples the first trigger portion to the second trigger portion; wherein the second trigger portion comprises: a semi-annular ring coupled to the trigger portion coupler, wherein the semi-annular ring comprises: a first tab; and a second tab; wherein the first tab and the second tab place the air horn in the ON state in response to the first trigger portion receiving pressure; and a lever mount coupled to the semi-annular ring, wherein the lever mount couples the trigger to the coupling device.
