BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention concerns a fixing means for fixing a barrel to the body of a firearm, said firearm further comprising an obturation mechanism and a cocking and fixing mechanism. In particular, the invention concerns a fixing mechanism for fixing the barrel to the body of the firearm for use in connection with small-calibre single-round and continuously firing, automatic arms.
Known fixing means and mechanisms attaching the barrel to hand firearms are complicated and frequently difficult to disassemble, i.e., the barrel is difficult to detach and to remount e.g. in connection with cleaning of the gun or when changing the barrel.
It is an object of the invention to provide a new kind of fixing means and mechanism for fixing the barrel to the body in particular for light--e.g. calibre less than 11 mm--automatic and mainly hand firearms, which means enables the barrel to be easily and rapidly detached and likewise to be easily and rapidly remounted. It is a further object of the invention to provide a fixing means that is simpler that any barrel fixing means known in the art.
SUMMARY OF THE INVENTION
The invention is based on fixing the barrel in support of the body with the aid of a particular, cradlelike and mainly U-shaped fork and attaching it to said fork with the aid of a fixing member. The fixing member consists of an eccentric lever disposed in the immediate vicinity of the barrel's muzzle part and which has been arranged in its locked position to press the barrel against the bottom of the fork. The barrel is preferably provided with a groove or notch and the bottom of the fork, or alternatively the eccentric locking member of the fixing member, has been fitted to enter said notch and thereby to lock the barrel unturnably fast to the fork.
Advantageously, the fixing means is so disposed on the muzzle part of the barrel that said notch or groove does not detract from the strength of the barrel in its highpressure portion.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is described in detail in the following with the aid of an embodiment example, referring to the attached drawing, wherein:
FIG. 1 presents in elevational view and partly sectioned, an automatic firearm according to the invention,
FIG. 2 presents in elevational view and partly sectioned, the barrel fixing means of the firearm of FIG. 1,
FIG. 3 presents the fixing of the barrel of firearm of FIGS. 1 and 2, viewed from the direction of the muzzle,
FIG. 4 presents in elevational view and partly sectioned, another barrel fixing means for an automatic firearm according to the invention, and
FIG. 5 presents the fixing of the barrel of the firearm of FIG. 4, viewed from the direction of the muzzle.
The automatic mechanical firearm depicted in FIGS. 1-3 comprises a body 2 provided with handle 14, with obturation mechanism 3 and with cocking and firing mechanism 4; the mode of functioning both of the obturation mechanism and the cocking and firing mechanism is conventional and shall not be more closely described here. The firearm furthermore comprises a barrel 1, which has been attached to the body 2 by the aid of a fixing means.
As taught by the invention, the fixing means comprises a mainly U-shaped fork 5 which has by its legs 6 been fixed to be borne by the body 2. The barrel 1 has been installed to be borne by the bottom or bridge 7 of the fork 5 and it has been fixed against said fork bottom with the aid of a fixing member 8. The fork 5 has been suspended by its legs 6 with the aid of a horizontal axle pin 10 placed above the barrel 1 and transversal to the barrel. The fixing member 8 urges the barrel 1 against the bottom 7 of the fork 5. On the barrel 1, a notch 12 has been provided, and the bottom of the fork 5 has been fitted to enter this notch to lock the barrel unturnably to the fork.
In the embodiment just presented, the fixing member 8 consists of an eccentric lever, that is part of the top housing 11 of the firearm, which has been pivoted to the body 2 of the firearm to be turnable in the vert
