Abstract

A flash unit includes a main body (7) having a cavity (15). The cavity (15) containing a standard blank cartridge (14) and a sachet (9) containing a metal powder or flash powder. There may be a firing pin 2.

Description

FLASH UNITS Field of the Invention
This invention relates to flash units and is concerned with the provision of a novel form of flash unit.
Summary of the Invention
According to a first aspect of the present invention there is provided a flash unit that includes a main body having a cavity containing a standard blank cartridge and a sachet containing a metal powder or flash powder.
The sachet containing the metal powder or flash powder is preferably contained within a cardboard tube.
According to a second aspect of the present invention there is provided a flash unit that includes a body having a chamber within which there is a sachet containing metal powder or flash powder and means for effecting ignition of the powder comprising a firing pin.
Brief Description of the Drawing
The single figure of the accompanying drawing is a sectional view of a flash unit in the form of a trip line device using a grenade flash chamber.
Description of the Preferred Embodiment
The device shown in the drawing is so designed that a standard blank cartridge can be used to blow a metal powder or flash powder into a cloud of dust and then ignite it to provide a brilliant flash or more intense explosion.
The metal powder or flash powder is contained in a sachet 9 placed in a cavity 15 within the cartridge chamber body 7 close to a blank cartridge 14 which is located in a communicating cavity 6 within the cartridge chamber body 7 so that the sachet 9 surrounds an array of flash holes 13 in the cartridge chamber. The sachet 9 containing the powder is enclosed within a cardboard tube 8 which is slipped over the cartridge chamber body 7 and, as the tube 8 is made of cardboard, it will be disrupted into a large number of harmless particles when an explosion takes place.
Ignition of the flash unit as a trip-line device is achieved by pulling out a rod or line pin 1 in the firing pin 2 to release balls 4 from their positions against a shoulder in a trip-line body 5, at which point a spring 3 will urge the firing pin 2 downwardly as viewed in the drawing to fire the blank cartridge. The trip-line body 5 includes an internally threaded portion 11 so that the cartridge chamber body 7 can readily be fitted in position. This permits versatile exchange of chamber bodies.
It is to be noted that, by providing an arrangement in which the cartridge chamber body 7 has a screw-threaded connection with the trip-line body 5, which is part of a standard impact grenade, it is to create a “Flash-Bang” impact grenade. A cross hole 12 is provided to accept a safety ring-pin (not shown) which provides a safety feature when setting up the device by blocking movement of the firing pin 2. A removable rod 10 extends from the base of the chamber body 7 to act as an anchor point and is provided with a ring to facilitate attachment of the device to a suitable fixed object. The rod 10 can be of such a length that it can be used to push out a spent cartridge case.

Claims (8)

Claims:-
1. A flash unit that includes a main body having a cavity containing a standard blank cartridge and a sachet containing a metal powder or flash powder.
2. A flash unit as claimed in Claim 1, in which the sachet containing the metal powder or flash powder is contained within a cardboard tube.
3. A flash unit as claimed in either of the preceding claims, which includes a firing pin acted on by a spring and releasable means for holding the firing pin in position.
4. A flash unit as claimed in Claim 3, in which the firing pin is positioned above the main body and in which a removable rod extends from the base of the main body.
5. A flash unit that includes a body having a chamber within which there is a sachet containing metal powder or flash powder and means for effecting ignition of the powder comprising a firing pin.
6. A flash unit as claimed in Claim 5, in which the sachet containing the metal powder or flash powder is contained within a cardboard tube.
7. A flash unit as claimed in Claim 1, in which the main body includes a portion that can be connected to the body of a standard impact grenade to create a “Flash-Bang” impact grenade.
8. A flash unit substantially as hereinbefore described with reference to and as shown in the accompanying drawing.
