Description

Technical field

[0001] The invention relates to a grenade launcher having a barrel which is arranged slidably relative to a trigger mechanism base between a front and a rear position, the barrel being locked in the rear locked position by a latch.Background art

[0002] The grenade launcher is a light weapon designed to destroy armoured targets, live forces and military equipment located in open terrain or in field-type shelters. The grenade launchers can fire a wide variety of grenades, such as high-explosive, armour-piercing, fragmentation and special types (thermobaric, smoke, illuminating, incendiary, gas, etc.).

[0003] The grenade launcher can be used either on its own or attached to an assault rifle.

[0004] When a new cartridge is being loaded or a spent one is being extracted, the barrel can either be tilted to the side or moved forwards.

[0005] In well-known grenade launchers, a hinged or sliding barrel locks into the latch.

[0006] These systems have highly complex and articulated locking elements that are difficult both to manufacture and to operate

[0007] For grenade launchers with forward barrel movement, a latch that is housed in the frame of the weapon is sometimes used to lock the barrel.

[0008] The goal of the invention is to design a barrel lock that is simple both to manufacture and to operate,Relevant prior art:

[0010] US2019 / 011219Summary of the invention

[0011] The said goal is achieved with a grenade launcher having a barrel which is arranged slidably relative to a trigger mechanism base between a front and a rear position, the barrel being locked in the rear locked position by a latch, according to the invention the principle of which is that the barrel is slidably mounted on guide rails, whereby the guide rails are arranged on opposite sides of the trigger mechanism base and the latch is positioned on a side of the barrel and is pushed by the force of a spring against one of the guide rails. The latch in the locked position of the barrel engages a recess in the corresponding guide rail

[0012] According to the preferred embodiment, the guide rails pass through longitudinal holes in the barrel.

[0013] According to another preferred embodiment, the guide rails are interchangeably connected to the trigger mechanism base, preferably screwed on.

[0014] The latch of a grenade launcher for right-handed persons is positioned on the left side of the barrel and engages a recess in the left guide rail.

[0015] When the barrel is in the extended position, the latch preferably rests on the front of the guide rail to prevent the barrel from retracting spontaneously.

[0016] An advantage of the solution according to the invention is that the guide rails allow several functions to be carried out. They primarily serve to guide the barrel, but also bear a locking recess, and their front, in conjunction with the latch, is used to lock the barrel in the open position.

[0017] The desired extent to which the barrel is to be extended can be easily adjusted by selecting different lengths of exchangeable guide rails.

[0018] The barrel guidance on the side guide rails and the locking by means of a latch positioned on the side of the barrel enable the weapon to be lowered in height, making it ergonomically more user-friendly when the grenade launcher is deployed under the host weapon or on a separate carrier. At the same time, the side latch is much more intuitively accessible to the non-shooting hand.

[0019] The barrel guidance on the side guide rails is independent of the weapon frame. Therefore, it is not restricted by the host weapon's interface and installation size for the purposes of mounting the grenade launcher. Known "frame" grenade launchers require the mounting interface to be a certain length, which can be a problem with a weapon that has a shorter forend. The grenade launcher according to the invention requires only a minimum length, which is also used for common accessories (flashlights, lasers, etc.), i.e. it can be mounted on a very short rifle.

[0020] The solution according to the invention maintains simplicity while delivering much greater reliability and more intuitive user handling, and is much easier to manufacture and maintain.Brief Description of Drawings

[0021] The invention will be explained in more detail by reference to examples of a particular embodiment of the grenade launcher according to the invention, shown in the accompanying figures, each of which represents the following embodiment: Fig. 1 - incomplete grenade launcher according to the invention with the barrel in the forward open position, attached to an MIL-STD-1913 host mounting interface; Fig. 2 - grenade launcher according to Fig. 1 with the barrel in the rear locked position; Fig. 3 - grenade launcher according to the invention, mounted on a host assault rifle. Examples of Embodiments

[0022] Figs. 1 and 2 show the main parts of the grenade launcher according to the invention. For the sake of simplicity, Figs. 1 and 2 do not show parts that are not necessary for the description of the modifications according to the invention.

[0023] In the role of an underslung weapon, the grenade launcher is attached to the lower host mounting interface 4 of a assault rifle 8 (see Fig. 3).

[0024] In stand-alone use, not shown, the grenade launcher is mounted via an MIL-STD-1913 type host mounting interface 4 on a carrier fitted with a handle, folding detachable shoulder support, and simple mechanical sights on the top rail of the host mounting interface 4.

[0025] The grenade launcher has a barrel 1, which is slidably arranged between the front and rear positions relative to the base 5 of the trigger mechanism.

[0026] Guide rails 2 are screwed to opposite sides of the trigger mechanism base 5. The barrel 1 is slidably mounted on guide rails 2 which pass through longitudinal holes in the barrel 1.

[0027] The barrel 1 is secured in the locked position by a latch 3, which is located on a side of the barrel 1 and is pressed to the guide rail 2 by an unshown spring.

[0028] In the grenade launcher for right-handed persons as per Figs, 1 and 2, the latch 3 is located on the left side of the barrel 1 from the shooter's viewpoint and fits into a pair of recesses 7 in the left guide rail 2. Taking into account the amount of stress from the shot, a single recess 7 is naturally sufficient for certain embodiments.

[0029] In the extended position of the barrel 1, the latch 3 rests on the front of the guide rail 2 and thus prevents the barrel 1 from retracting spontaneously. This locking of the barrel 1 in the open position makes it easier for the user to remove a spent cartridge that is otherwise difficult to extract, where greater force is required to remove the cartridge from the chamber.

[0030] When the grenade launcher is being loaded, the latch 3 is pressed against the force of the unshown spring, causing the latch to disengage from the recess 7. By sliding along the guide rails 2, the barrel is moved to the forward position (see Fig. 1),

[0031] A cartridge is then inserted into the rear opening of the barrel 1. The barrel 1 is moved to the rear closed position, where the latch 3 automatically engages the recess 7 in the left guide rail 2 under the pressure of the spring, thus securing the barrel 1 and making the grenade launcher ready to fire, The shot is fired by pulling the unshown trigger, which activates the unshown trigger mechanism.

[0032] After the shot is fired, the shooter presses the latch 3, thereby releasing the barrel 1. The shooter moves the barrel 1 to the forward position so that the spent cartridge can be extracted.

[0033] When the barrel is extended to the maximum forward position, the latch 3 rests against the front of the guide rail 2 under the pressure of the spring and locks the barrel 1 in the open position. This makes it easier to extract the spent cartridge. After the latch 3 is depressed, the barrel 1 can then be moved back along the guide rails 2 to the closed position.List of reference signs
