Definitions

• the invention relates to the technical sector of launchers for the firing of large caliber projectiles.
• the object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner
• the present invention relates to a particularly compact and ergonomic large caliber firearm, in particular with superimposed double barrels tilting at 180 ° designed so as to allow, optionally, the mounting of a third small caliber rifled rifle firing a powerful munition of handgun for a short model or with a grazing path for a long model with stock, the weapon being equipped with a single trigger even with three barrels.
• the design of the two models according to the invention authorizes the use of boxes for a very compact transport, for example 46 x 24 x 8 cm (shoulder model 45 cm of cannons) and 24 x 24 x 8 cm (fist model 20 cm of cannons ).
• the propellant distribution device and their low pressure allow the firing of projectiles with a fragile envelope, which reduces the mass of structure by increasing the capacity in active products of grenades with neutralizing effects while avoiding the formation of dangerous fragments during the use of the pyrotechnic disperser.
• the weapon comprises at least one barrel and has a handle acting as a stock having at the top, a single inverted trigger, said handle being arranged in alignment with the barrel or barrels.
• the handle is arranged in coaxial alignment with the barrel without projecting in height over the entire coast of said barrels.
• the barrels can be folded angularly by 180 ° to be positioned in juxtaposition and very substantially parallel to the handle acting as a butt.
• Another problem which the invention proposes to solve is to be able to fire any of the shots from the one and only trigger.
• the single inverted trigger is subject to two levers mounted at right angles, which actuate one or the other of the corresponding triggers, according to the positioning of a selector.
• the large caliber departure trigger system includes a stop limiting the trigger stroke to very substantially 2 mm, or approximately, 1/3 of the stroke required for the start of the scratch when the selector is in position. median, thus excluding any simultaneous departure of a large caliber cannon with the rifled shot.
• the system for triggering a striped hit has two safety features, namely a dog safety device and a double trigger, said system also comprising a special snap mechanism to raise awareness of the start if it is previously armed.
• the weapon has a rapid laser beam sighting system.
• Figure 1 is a front view of the weapon according to the invention, showing the trigger system with the selector.

• FIG. 13 is a view showing the security system 0 for starting shots.
• the battery is fixed vertically behind the breech plate (O), while the dogs are opposite and have an external handle (1), for an ergonomic armament between the thumb and the index finger.
• the trigger (2) is in the inverted position and acts by its vertical back (3) on a pusher (4) held in a part of a selector sliding vertically.
• the external control of the selector (5) is placed on the left and is in the form of a button (6) with ball catch and spring in three positions, namely a high position for the use of the upper barrel, a middle position in safety and a low position for the use of the lower barrel.
• the battery and the expansion system are integrated in a fairing composed of two flanges (7) arranged vertically behind the cylinder head plate (O) and integral with the latter which stiffens the assembly.
• a handle (8) is fixed to the rear of the flanges (7), in alignment with the assembly, barrels, battery heads.
• the tilting axis (9) connects the rear of the lower barrel, with the flanges (7) projecting from the bottom and the top of the breech plate.
• the lock is articulated on the flanges, the latch of the lock being fixed at the top and at the rear of the upper barrel, control of the lock by pedal on the left side of the battery fairing (10).
• the long model (long gun) is fitted with a U-shaped metal profile stock, which is fixed by screws at the top and bottom of a handle (11).
• a layer plate (12), of molded material of variable thickness, is removably mounted at the end of the handle (11).
• the mechanical sighting system varying from one model to another, the handgun being rather intended for live shooting, is provided with a fixed device, notch cut in the bolt and its tenon and protected handlebar mounted on a ramp at the end of the upper barrel (15 and 16).
• the long gun intended for curved shooting has a wide angle rise mounted on the butt of the butt.
• a slider eyelet (14) lengthens the line of sight in relation to the raised and foldable handlebars at the end of the upper barrel (13).
• the locking of the third barrel (17) on the breech plate is ensured over a semi-circular reach of 170 ° by a latch with the same arc (18) kept open by a ball pawl (19) and closed by a latch (20) .
• a laser (21) fixed on the support sleeve (22) of the gun allows a fast and precise aiming by placing the light point on the target.
• a contact under rubber protection is fixed under the lower barrel at the location of the grip, the pressure of this establishing contact with the light system.
• the two triggers (25 and 27) are controlled by a second expansion back mounted horizontally by fitting at the end of the expansion axis (29).
• the lever arm thus formed releases the position of the trigger (27) at 2/3 of the pressure on the trigger, the last 1/3 preparing for departure by detaching the trigger (25).
• the start when the trigger (25) is released, can be sensitized by first arming a snap system (30) pressurized at the end of the trigger lever (29).
• the ramp of the breaker (31) passing by force under the lever (29) performs this function without the finger of the shooter.
• the safety device (32), in the low position interposes a metal plate between the breech plate and the dog's head, which prevents striking of the striker (33) mounted on a pin spring (34).
• Percussion devices controlled by a single trigger, are designed in such a way that the start of two simultaneous shots is made impossible, even if the three dogs are armed and without safety.
• Figures 12 and 13 illustrate the case of the three armed dogs, safety (32) of the striped strike not lowered.
• the selector is positioned on one of the large caliber smooth strokes (L2), pusher (4-P2) opposite the trigger (36-G2).
• a pressure on the trigger (D) equal to 2 mm of stroke which is transmitted by the lever (3) to the pusher (4-P2) generates an advance of the latter equal to 1 mm passed on to the trigger (36 -G2), sufficient stroke to start the smooth stroke of large calbire (L2).
• the trigger stop (35) limits the travel of the parts used as defined in this case (firing of one of the large caliber smooth shots).
• the start of the rifled shot requires a defined stroke equal to 6 mm on the trigger, this stroke is only obtained in the only case where the selector is in the middle position, pusher (4) in free passage between the triggers (G1 and G2 ) position normally defined when you want to trigger the strike from the strike by canceling the possibility of starting heavy shots.
