Device with combustible charge with smoke-generating, tear-generating or signaling effects

Abstract

Device with combustible charge with smoke-generating, tear-generating or signaling effects, which comprises a casing ( 1 ) housing a series of charges ( 2 ) traversed by an ignition cord ( 16 ), which casing is closed by means of a cover ( 3 ) which delimits an inner chamber ( 25 ) and carries a fuse ( 18 ). Between the charges ( 2 ) and the end wall ( 6 ) of the casing ( 1 ) there is a spacer ( 7′ ) which defines a chamber ( 8 ), between said end wall ( 6 ) and the nearest charge ( 2 ), and which may consist of a cylindrical wall, inside which are housed one or more parachutes ( 26 ), to each of which a charge ( 2 ) is connected.

1 . A device with combustible charge with smoke-generating, tear-generating or signaling effects, which comprises a casing housing a series of charges ( 2 ) of combustible, smoke-generating, tear-generating or signaling mixture, which have a coaxial passage ( 15 ) through which an ignition cord ( 16 ) passes, which casing is closed by a detachable cover ( 3 ) which delimits an internal chamber and carries a fuse ( 18 ) whose activation gives rise to ignition of the cord and thereby the ignition of the charges, wherein, between the combustible charges and the end wall ( 6 ) of the casing, there is a spacer ( 7 ) which defines a chamber between said end wall and the closest charge, in which chamber, and also in the chamber delimited by the cover, once combustion of the charges has been initiated, the combustion gases are progressively stored until sufficient pressure is achieved to cause detachment of the cover and expulsion of the charges outside the casing.  
     
     
         2 . The device as claimed in  claim 1 , wherein the cover of the casing is coupled in a tight-fitting manner inside said casing and is externally held on by means of crimping of the wall of the casing on the cover, the wall or skirt of said cover resting on the combustible charges in order to push them against said spacer.  
     
     
         3 . The device as claimed in  claim 1 , wherein the spacer ( 7 ′) consists of a cylindrical wall, close to the wall of the casing, which delimits a space housing one or more parachutes ( 26 ), as many as there are combustible charges ( 2 ) housed in the casing, each one of said parachutes being connected to the housing of one of the combustible charges.  
     
     
         4 . The device as claimed in  claim 3 , wherein the casing houses a single combustible charge ( 2 ) and the space defined by the cylindrical wall houses a single parachute ( 26 ), the casing of said charge having, from the outer surface of said end wall, a ring ( 27 - 28 ) to which the parachute is connected.
