Definitions

• Grenade Launcher having a barrel which is arranged slidabiy relative to a trigger mechanism base
• 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.
• 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.).
• the grenade launcher can be used either on its own or attached to an assault rifle.
• the barrel 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.
• a latch that is housed in the frame of the weapon is sometimes used to lock the barrel.
• the goal of the invention is to design a barrel lock that is simple both to manufacture and to operate.
• 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
• the guide rails pass through longitudinal holes in the barrel.
• the guide rails are interchangeably connected to the trigger mechanism base, preferably screwed on.
• 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
• the latch 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.
• guide rails allow several functions to be carried out. They primarily serve to guide the barrel, but also bear a lucking recess, and their front, in conjunction with the latch, is used to lock the barrel in the open position.
• the desired extent to which the barrel is to be extended can be easily adjusted by selecting different lengths of exchangeable guide rails.
• 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.
• the side latch is much more intuitively accessible to the non-shooting hand.
• 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.
• 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.
• Fig. 1 - incomplete grenade launcher with the barrel in the forward open position, attached to an MIL-STD-1913 host mounting interface;
• Fig. 3 - grenade launcher mounted on a host assault rifle.
• Figs, 1 and 2 show the main parts of the grenade launcher according to the invention.
• Figs. 1 and 2 do not show parts that are not necessary for the description of the modifications according io the invention.
• the grenade launcher is attached to the lower host mounting interface 4 of a assault rifle 8 (see Fig, 3),
• 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,
• 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.
• 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 .
• 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.
• 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.
• the latch 3 In the extended position of the barrel 1 , the latch 3 rests on the front of the guide rail 2 and thus preyvents 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.
• the latch 3 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.
• 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,
• 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.
