Clamped nut. An appropriately constructed weapon is

CONFIRMATION COPY from WO2008 / 060310 and US Pat. No. 7,610,844.

From EP 0 666 462 a weapon is known in which a pin is used to make a positive connection between the housing and barrel, so that the barrel is fixed together with the cartridge chamber on the housing. A disadvantage of this embodiment is that the clamping of the barrel takes place only from one side, namely from below. This can lead to tension and concomitant impairment of the

Running vibrations in the shot and thus the weapon precision come. Also, there is through the use of only a rearwardly extended, adapted for running recording, system bed with molded

Magazine recording and the use of a separate shaft attached thereto for receiving the composite not the possibility of an integral formation of the system housing and hand protection and possibly additional equipment mounting points along the gun barrel in

Weft direction. In particular, a corresponding, on the

Top running mounting option with regard to the installation of sighting is considered to be particularly advantageous.

A one-piece housing, which forms the closure housing and the hand guard, is known from US 2006/0236582. Here, the attachment of the barrel or the locking sleeve by means of a

Clamping, in which by means of at least one screw two integrally formed on the housing bending regions against the locking sleeve can be pressed, whereby it is firmly clamped and held and fixed in particular in the axial direction positively and non-positively. Object of the present invention is to provide a locking possibility for the barrel and / or the locking sleeve, wherein the housing can be easily formed.

This object is achieved according to the first idea of the invention in that at least two locking means transversely or obliquely to the barrel axis and at equidistant intervals around the barrel axis arranged in a housing part of the weapon introduced, in particular can be screwed, and against the locking sleeve or a

Press intermediate part to lock the locking sleeve. Advantageous embodiments of this invention will become apparent from the features of the dependent claims back to claim 1. By distributed around the circumference arranged locking means, which may be screws in its simplest embodiment, the barrel or the locking sleeve is pressed uniformly against the housing and held in position so that no tension occurs. This object is achieved according to a second aspect of the invention in that at least two locking means transversely or obliquely or tangentially to the barrel axis in a housing part of the weapon introduced, in particular screwed or clamped, with each locking means partially supported on the housing part and form-locking the locking sleeve and / or an intermediate part and / or a closure guide sleeve and / or the barrel in the axial direction locked relative to the housing. Particularly preferred are only two locking means, which are arranged in particular parallel to each other, is provided. These may be the intermediate part, the closure guide sleeve and / or the barrel between them

pinch. In addition, it is ensured by the positive connection that the parts are accurately positioned relative to the housing.

By using two, three or four symmetrical to

Running axis arranged locking means which the positive axial fixation of the barrel, the locking sleeve and / or the

Guarantee closure guide sleeve relative to the housing, it is achieved that the parts are loaded symmetrically. As a result, the problem of unilateral tension is advantageously eliminated.

The embodiment of the invention advantageously also allows a one-piece housing, which is understood to include a housing which the closure and / or the closure receptacle and / or the Closure movement range and at least the hand protection includes.

On the housing advantageously several additional components can be attached. For this purpose, the housing has standardized outer contours, as they have been international standard for years.

In FIGS. 14 and 15, the guide sleeve 18 is additionally pushed over the closure guide sleeve 20, which is positively locked, e.g. by means of a latching connection, is connected to the locking sleeve 12. This ensures that the two parts, at least in the axial direction relative to each other can not be moved against each other without releasing the positive connection. It is of course also possible for the locking sleeve to have a collar,

corresponding to the collar 2b of the first embodiment, which with the radially inwardly directed collar 18k of

Guide sleeve 18 cooperates. The guide sleeve 18 has two parallel and tangentially arranged through holes or recesses 18b, through which the bolts 15 engage. The

Through holes 18b are also arranged in the region of the recesses 12a of the locking sleeve 12, so that the parts 11, 12, 14, 18 and 20 are fixed relative to one another by the inserted bolts 15. The closure guide sleeve 20 has molded-on tabs 20p, which in turn have holes 20m, which serve for attachment to the lower weapon housing or magazine housing, not shown.

FIG. 16 shows a section through the locking sleeve 12 with a locking pin 15 which presses against the contact surface 12a.

FIG. 17 shows a cross-sectional view through the plane of the locking bolts 15. The bolts 15 may be designed with a diameter such that they embrace an interference fit in the housing recesses 14a and the recesses 20a, 18b and 12a. They then lie firmly against the inner wall 14i of the housing recesses 14b and center the housing 14 with the barrel 11, the locking sleeve 12 and the closure guide sleeve 20.

FIGS. 18 to 23 show a further possible embodiment of the weapon according to the invention. FIG. 18 shows a perspective view of the barrel 1, the locking sleeve 2 and the closure 30. The barrel 1 is screwed into the locking sleeve. The

Locking sleeve 2 has a circumferential outwardly directed collar 2v, against which the locking means 25 press in the axial direction R after they have been pushed or pushed into the housing openings 14a. The locking means 25 are pin-shaped and have a head 25b and a shaft 25d. The closure 30 is stepped, with its end 30 c being encompassed by a guide sleeve 31 in the form of a C, via which it is supported on the closure housing 14. FIG. 19 shows a partial sectional view of the weapon in the region of the connection of the barrel 1, the locking sleeve 2 and of the barrel

Shutter housing 14. The locking means 25 press against the peripheral collar 2v and the locking sleeve 2 with its front end against the 2st assets 14 _TO the closure housing 14 by the locking means 25 of the running are thus one and the

Locking sleeve 2 securely held in position. The locking agent 25 has a bearing surface 25c, with which it presses against the projection 2v of the locking sleeve. The abutment surface 25c is formed by a wall of a recess 25a extending along the shank 25d. The walls bounding the recess 25 are slightly beveled in the direction of the end 25e, so that a trouble-free introduction of the locking means during assembly of the weapon is ensured.

FIG. 20 shows the parts according to FIG. 19 from another one

Line of sight. Above the barrel 1 and the locking sleeve 2, a part 40 is arranged, which in a housing opening 14z of the

Closing housing in particular fits exactly and from

Lock housing 14 is secured against rotation. The part 40 has a groove-shaped recess 40b, which engages around a not shown projection of the locking sleeve 2 accurately, whereby the locking sleeve is held relative to the closure housing in a unique position.

FIG. 21 shows a perspective partial view of the

Closure housing 14 and the hand protection molded or attached thereto. The two recesses 14a for the locking means are arranged parallel to each other on both sides of the barrel or the locking sleeve.

Figures 22 and 23 show the end-side support of the stepped closure 30. The closure 30 has two regions 30a and 30b, which have different outer diameters. The end 30c is encompassed by a c-shaped ring 31, which rotatably rests in the closure housing 14. For this purpose, the ring 31 has radial projections 31a, which engage in grooves 14n of the closure housing 14. The inner diameter of the ring corresponds to the outer diameter of the end portion 30c. The outer diameter of the ring corresponds in turn to the inner diameter of the

Closure housing 14. By using differently shaped rings 31 thus different closures in a and the same closure housing are installed. In addition, there is a significantly improved linear guidance of the closure in the rear region to prevent tilting moments during the actuation process. It goes without saying that the locking means 25 can also press against the barrel 1. Also, a part, for example in the form of a sleeve or a ring, between locking means and barrel or

Locking sleeve can be arranged.
