Definitions

  • the invention relates to a device for generating sounds and/or for dispersing paint, dyes, smoke or similar materials into the air for simulating a range of explosive effects for use in paint-balling, the film industry or as training tool for military, police or other emergency services personnel.
  • the device can be used as a flare for attracting attention in both emergency and non-emergency situations.
  • the invention provides an electronically actuated hand grenade which can be repeatedly used to discharge a variety of blank cartridges containing paints, dyes or other special effects cells. It is safe and reliable to use and inexpensive to manufacture.
  • the cartridges and the discharging device are transported and stored separately and are preferably assembled shortly before or more preferably immediately prior to discharge there is a reduced risk of the effects cell being discharged in error before the device is required.
  • the device When the device is to be used as a flare in emergency situations it has the advantage that because it can be reused repeatedly large numbers of blank cartridges can be discharged using a single device making it more space efficient.
  • the device can discharge different types of blank cartridges each containing different effects cells a range of cartridges can be carried and the most appropriate selected for use in different circumstances for example at night, in heavy seas or desert conditions or with properties such as slow sustained release or noise to help maximise the chance of the flare being spotted from either the air, sea or ground.
  • the invention in a first aspect relates to a device comprising an electronically actuated hand grenade for discharging a blank cartridge.
  • the device is reusable.
  • the blank cartridge when the device is discharged the blank cartridge emits one or more of smoke, percussion, flash, flash bang, whistle, crackle, scream, flash crackle, strobe, white phosphorous simulation or other special effect.
  • the blank cartridge when the device is discharged the blank cartridge emits a flare. In another aspect of the invention when the device is discharged the blank cartridge emits a paint, dye or stain.
  • the blank cartridge when the device is discharged the blank cartridge emits a harmless coloured or scented gas or vapour, or one or more solid or filled non-lethal projectiles.
  • the blank cartridge comprises an effects cell a contact means and a detonator.
  • the contact means comprise one or more circular or ring shaped connector regions.
  • the device further comprises a timer for delaying the discharge of the blank cartridge.
  • the timer is preset to delay the discharge of the blank cartridge by between lsec and 45 minutes.
  • the device further comprises a light which is illuminated when the blank cartridge has been actuated and is about to be discharged.
  • the device emits a sound when the blank cartridge has been actuated and is about to be discharged.
  • the device a sound is emitted after the blank cartridge has been discharged.
  • the device further comprises one or more openings through which the flash bang, flare, paint, dye or stain is released after the blank cartridge has been discharged.
