GRENADE LAUNCHER

Abstract

A grenade launcher, comprising a barrel (10), a trigger mechanism base (3) and a breech (2) wherein the trigger mechanism base (3) is adapted to be mounted on a host rail interface (1). On the opposed sides (3) of the trigger mechanism base (3), guide rails (5, 8) are arranged for sliding mounting of the barrel (10). The host rail interface (1) is clamped between the breech (2) and the trigger mechanism base (3). The breech (2) is fitted with a cavity (11) that surrounds one of the guide rails (5). The inner wall of the cavity (11) is pressed to this guide rail (5) by a detent (4) that is insertable between this guide rail (5) and the opposed inner wall of the cavity (11) that is inclined in a wedge-like way. A pin (6) bears on this guide rail (5) from the inner side, the pin being mounted in a sliding way in a recess transversally in the breech (2) and fitted with a compression spring (7).

Claims

1. A grenade launcher, comprising a barrel (10), a trigger mechanism base (3) and a breech (2) wherein the trigger mechanism base (3) is adapted to be mounted on a host rail interface (1), and on the opposed sides (3) of the trigger mechanism base (3), guide rails (5. 8) are arranged for sliding mounting of the barrel (10), characterized in that the host rail interface (1) is clamped between the breech (2) and the trigger mechanism base (3) and the breech (2) is fitted with a cavity (11) that surrounds one of the guide rails (5) and the inner wall of the cavity (11) is pressed to this guide rail (5) by a detent (4) that is insertable between this guide rail (5) and the opposed inner wall of the cavity (11) that is inclined in a wedge-like way and a pin (6) bears on this guide rail (5) from the inner side, the pin being mounted in a sliding way in a recess transversally in the breech (2) and fitted with a compression spring (7).

2. The grenade launcher according to claim 1, characterized in that the host rail interface is the MIL-STD-1913 (STANAG 4694) interface.

3. The grenade launcher according to claim 1, characterized in that the detent (4) is pressed to the locking engagement between the guide rail (5) and the opposed inner wall of the cavity (11) having a wedge-like inclination by a detent spring (9).

[0018] FIG. 2a side view of the breech and the trigger mechanism base of the grenade launcher on a host rail interface;

[0019] FIG. 3a sectional view of the breech and the trigger mechanism base of the grenade launcher, locked on a host rail interface;

[0020] FIG. 4the embodiment of FIG. 3 in the unlocked state.

EXAMPLES OF EMBODIMENTS

[0021] The grenade launcher according to FIG. 1 has a barrel 10 that is mounted in a sliding way between the front and rear position on guide rails 5, 8, arranged at the opposed sides of the trigger mechanism base 3.

[0022] The trigger mechanism base 3 is adapted to be slid onto a host rail interface 1 of the MIL-STD-1913 STANAG 4694 type. This host rail interface 1 may be either part of a host weapon, e.g., an assault rifle, or a grenade launcher carrier if the grenade launcher is used in a standalone way.

[0023] The breech 2 is also attached to the host rail interface 1 in such a way that the host rail interface 1 is clamped between the breech 2 and the trigger mechanism base 3 (see FIGS. 3 and 4).

[0024] The breech 2 is fitted with a cavity 11 that surrounds the left guide rail 5 and the inner wall of the cavity 11 is pressed to this left guide rail 5 by a detent 4 that is inserted between the left guide rail 5 and the opposed inner wall of the cavity 11 that is inclined in a wedge-like way, forming a wedge lock.

[0025] A pin 6 that is mounted in a sliding way in a recess transversally in the breech 2 and fitted with a compression spring 7 bears on the left guide rail 5 from the inner side. The pin 6 is pressed to the left guide rail 5 by the compression spring 7 (see FIGS. 3, 4), thus pressing the breech 2 to the side and thereby the prism of the host rail interface 1 towards the trigger mechanism base 3. This way, the plays resulting from production tolerances are delimited.

[0026] The detent 4 is pressed to the locking engagement between the guide rail 5 and the opposed inner wall of the cavity 11 having a wedge-like inclination by a detent spring 9.

[0027] The grenade launcher can be disassembled from the host rail interface 1 of the host weapon or the grenade launcher carrier without the use of tools.

[0028] During the disassembly, the barrel 10 is first moved to the front position, which at the same time causes removal of the barrel 10 from the not shown collar at the bottom edge of the breech 2.

[0029] Then, the breech 2 is unlocked by pushing the detent 4 downwards against the action of the detent spring 9.

[0030] After pressing the detent 4, which extends between the left guide rail 5 and the opposed inner wall of the cavity 11 having a wedge-like inclination, the breech 2 can be tilted in the trigger mechanism base 3 to the left by approx. 45 (see FIG. 4) as seen from the shooter's view, which will simultaneously force the pin 6 against the action of the compression spring 7.

[0031] After tilting of the breech 2, the entire grenade launcher can be slid backwards or forwards along the host rail interface 1, and thus the grenade launcher can be easily removed from the host rail interface 1.

[0032] The grenade launcher is mounted on the host rail interface 1 of the host weapon or a grenade launcher carrier in the reverse order.
