Abstract

Provided is a cartridge for an electrically-ignited simulated firearm and a simulated firearm using the cartridge remarkably similar to a real firearm and a cartridge used in a real firearm, wherein the simulated firearm emits a discharge sound similar to a real firearm, generates muzzle flash and smoke from a muzzle and is capable of loading and ejecting the cartridge, and the cartridge is safe and reusable. An inner member 120 that is slidable inside an outer case 110 of a cartridge 100 and loaded with powder is formed into a stepped cylindrical shape with a small diameter section capable of partially projecting from an opening 112 of the outer case 110, and has a front powder chamber 122 and a rear powder chamber 123 that communicate with each other via a fuse hole 124, a base member 130 is formed to fit in the outer case 110 via an insulating member 131, and an ignition member 140 is configured to be installed between the inner member 120 and the base member 130.

Claims

1. A cartridge for an electrically-ignited simulated firearm, comprising:

a case body having an opening at least in a front portion and loaded with powder therein;

an ignition member that electrically ignites the powder; and

a base member installed in a rear portion of the case body to be electrically connected to the ignition member,

wherein the case body is composed of an outer case formed into a hollow cylindrical shape, and an inner member slidable inside the outer case and loaded with the powder,

the outer case has an opening in a front portion that stops the inner member from dropping from the outer case, and an engaging groove provided along a circumference in a rear portion thereof,

the inner member is formed into a stepped cylindrical shape with a small diameter section capable of projecting from the opening of the outer case, and has a front powder chamber having an opening in a front portion and loaded with ejection powder and a rear powder chamber having an opening in a rear portion and loaded with propulsive powder,

the front powder chamber and the rear powder chamber are formed to communicate with each other via a fuse hole,

the base member is formed to fit in a rear end portion of the outer case via an insulating member, and

the ignition member is installed between the inner member and the base member.

2. The cartridge for a simulated firearm according to claim 1, wherein the outer case is composed of a front case and a rear case that are detachably engaged with each other.

3. The cartridge for a simulated firearm according to claim 1, wherein the ignition member is composed of an insulating member and formed into a ring shape having a hollow, through which a heating element is provided while extending to both surfaces of the ignition member, and in which ignition powder is loaded.

4. The cartridge for a simulated firearm according to claim 3, wherein an auxiliary conductive plate composed of an electrical conductor having a diameter slightly larger than an inner diameter of the outer case is provided between the ignition member and the inner member to electrically connect the heating element of the ignition member with the outer case.

5. An electrically-ignited simulated firearm capable of loading the cartridge for a simulated firearm according to claim 1 provided in a rear portion of a barrel, including a bolt that slides and pushes the cartridge in a direction of the barrel, and capable of igniting powder in the cartridge by operating a trigger,

wherein the barrel has a stopper that comes into contact with the cartridge on a tip side, and an ejection hole penetrating from the stopper to a tip of the barrel, and

the bolt includes an engaging claw that engages with an engaging groove provided on an outer case of the cartridge, a penetration hole or a penetration groove to receive an ejector that loosely fits therein and comes into contact with a base of the cartridge when the cartridge moves backward, and a current supply member that supplies a current from the base member.

6. The cartridge for a simulated firearm according to claim 2, wherein the ignition member is composed of an insulating member and formed into a ring shape having a hollow, through which a heating element is provided while extending to both surfaces of the ignition member, and in which ignition powder is loaded.

7. The cartridge for a simulated firearm according to claim 6, wherein an auxiliary conductive plate composed of an electrical conductor having a diameter slightly larger than an inner diameter of the outer case is provided between the ignition member and the inner member to electrically connect the heating element of the ignition member with the outer case.
