Abstract
Abstract A portable defense device combining a flashlight with a renewable, interchangeable cylinder containing compressed gas which may be used to generate a noise, to disperse dye and/or an odoriferous spray. The compressed gas may be stored in a canister which may take the form of a spray can having the typical articulated dispensing nozzle which is then received in an articulated throat assembly displaced to release the contents by a pivoted trigger engaging a pivoted arm assembly. In the normal state the trigger is aligned over the exit opening of the throat, thus protecting the dispensing nozzle from inadvertent release, and when released the trigger aligns to engage the arm.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
210 words
A personal defense device comprising: a hollow housing including a first elongate cavity formed on the interior thereof, said first cavity terminating in an orifice at one end thereof; a container of compressed gas received on the interior of said first cavity, said container including a dispensing nozzle at one end thereof adapted to dispense said compressed gas upon the inward articulation thereof, said container being aligned in said first cavity to deploy said nozzle towards said orifice; a throat assembly generally formed as a conical frustum surface engaging the nozzle and providing a discharge flow path for the compressed gas issuing from the nozzle, said throat assembly disposed in the cavity at said one end and aligned to translate within said orifice to effect the articulation of said nozzle, said throat assembly including two exteriorly directed opposed projections on the exterior thereof; a pivoted lever suspended inside said housing for pivotal articulation and aligned to translate said projections on said throat assembly thereby; and a pivoted trigger assembly conformed as an L-shaped surface hinged at one end within said housing proximate said throat assembly and adapted to align the free leg thereof over said orifice in one position thereof and to movably engage said lever in another position thereof.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
26 words
Apparatus according to claim 1 wherein: said trigger includes serrated surfaces aligned for mating engagement with said lever assembly in said second position of said trigger.
Claim 4
Dependent Claim
31 words
Apparatus according to claim 2 wherein: said lever assembly is conformed to advance said throat assembly and said nozzle to release said compressed gas upon the engagement of said serrated surfaces.
Claim 5
Dependent Claim
35 words
Apparatus according to claim 3 further comprising: a second cavity formed in said housing and including a lamp at one end thereof; and battery means stored in said second cavity for excitation of said lamp.
Claim 6
Dependent Claim
21 words
Apparatus according to claim 4 further comprising a buzzer stored in said housing and adapted for selective connection to said batteries.
