Training stun grenade

Abstract

A training stun gun consisting of a main valve body and a base cylinder which are screwed together and have a cavity therein. A CO2 cartridge is located in the cavity. The lower end of the main valve body has a piercing element therein that faces the top of the CO2 cartridge . When the two bodies are screwed together to a certain extent, the piercing element will pierce the top of the CO2 cartridge and release high pressure fluid. A valve assembly controls the release of the high pressure fluid to a burst diaphragm cap on top of the main valve body. The cap will burst and release the high pressure with an explosion-like noise. No pyro-technique is involved.

1 . A training stun grenade consisting of a base cylinder and a main valve body screwed together to form a structure, a cavity is located within said structure, a CO2 cartridge is located within said cavity, a valve assembly is located within said main valve body having means to be activated from an outside of said main valve body, a burst diaphragm cap
 is located on top of said main valve body, means for piercing said CO2 cartridge to release its high pressure fluid therein, said valve, when activated, will let the high pressure fluid escape into the cap of said burst diaphragm to result in a bursting of the diaphragm with an explosive-like noise to achieve the object of the training stun grenade.   
   
   
       2 . The training stun gun of  claim 1 , wherein said valve body has O-rings thereon to prevent high pressure fluid from escaping toward the outside of said stun gun. 
   
   
       3 . The training stub of  claim 1 , wherein said means for activating said valve body is an elongated spoon movably mounted at a top of said main valve body, means for movably connecting said spoon to said main valve body to move said valve body relative to said main valve body including means for preventing said movement. 
   
   
       4 . The training stun gun of  claim 3 , wherein said means for preventing said movement is a retaining clip surrounding said main valve body and overlapping said spoon 
   
   
       5 . The training stun gun of  claim 1 , wherein said means for piercing consists of a piercing disc having a piercing point on its underside, said piercing disc is located on an underside of said main valve body and in the vicinity of a top of said CO2 cartridge, when said main valve and said base are screwed to a certain extent, the piercing point of said piercing disc will pierce said top of said CO2 cartridge. 
   
   
       6 . The training stun gun of  claim 1  , wherein an underside of said burst diaphragm cap has a thickness reduction on about 85% of its circumference as an aid to enhance a bursting of said cap. 
   
   
       7 . The training stun gun of  claim 1  having means thereon for bleeding off the high pressure fluid in case of failure of the stun gun. 
   
   
       8 . The training stun gun of  claim 7 , wherein said means for bleeding off is an orifice in the wall of the valve body and is in line with said valve body.
