ABSTRACT:
This invention relates to a portable gun for discharging highly pressurised capsicum or lachrymatory material, for use in law enforcement.
A requirement exists for a portable gun for discharging highly pressurised fluid material that is both safe and reliable in operation, yet is simple in construction and capable of being readily serviced to mart operational requirements. Such a portable gun potentially has utility for discharging fluid material in law enforcement applications.
According to the present invention, there is provided a portable gun for discharging highly pressurised capsicum or lachrymatory material for use in law enforcement, including a pressure vessel, a valve assembly connected to an outlet of the vessel for controlling discharge of the material, the valve assembly including a trigger for actuation thereof, and an elongate barrel coupled to the valve assembly for directing the discharge of the material, wherein the pressure vessel, valve assembly and barrel are adapted to be rigidly connected and wherein the pressure vessel is provided with liquefied CO
2
in combination with said material.
Preferably the valve assembly is removably connected to the pressure vessel to allow for replenishment of said material and is adapted to allow the pressure vessel to be recharged with liquid CO
2
through an outlet nozzle of the gun.
In a preferred embodiment of the invention, be gun is designed to be used in an orientation in which the longitudinal axes of the vessel and the barrel are generally horizontally directed, with the gun being carried by a sling on the body of the user so that the vessel lies between the torso of the user and an arm of the user, with the trigger being in a position to be actuable by the hand of that arm. Advantageously, the valve assembly includes a pistol grip extending from the valve assembly substantially perpendicular to the longitudinal axis of the barrel and the trigger is located adjacent the pistol grip whereby the trigger is actuable by squeezing the trigger towards the pistol grip. Advantageously, the barrel also includes a hand grip which is able to be gripped by the other hand of the user to facilitate manipulation and aiming of the gun.
Preferably, the valve assembly includes a rupture disc assembly arranged in fluid communication with the pressure vessel. The rupture disc assembly acts as a safety means to release pressure in the event that pressure in the pressure vessel exceeds a predetermined amount.
Conveniently, a trigger guard extends around the trigger from a lower portion of the pistol grip to the barrel.
Preferably, an insulating and protective sleeve substantially surrounds the vessel.
Further according to the invention, there is provided a portable gun for discharging highly pressurised fluid material such as tear gas or capsicum spray, said gun including an elongate refillable pressure vessel for storing under pressure fluid material to be discharged, a valve assembly coupled to an outlet of the pressure vessel, and a discharge barrel coupled to the pressure vessel via the valve assembly and through which the material is discharged when the valve assembly is opened, the longitudinal axis of the barrel being orientated in the same direction as the longitudinal axis of the pressure vessel, a manually-operable trigger coupled to the valve assembly for opening and closing the valve assembly, and a sling for supporting the gun from the body of a user so that the gun can be supported from the user's body with the pressure vessel lying between the torso of the user and an arm of the user and with the longitudinal axes of the pressure vessel and barrel being generally horizontally directed.
