Description

Chamber unit for self-loading weapons Chamber units for self-loading weapons with conversion device from single loader to self-loader, in which a locking piece the telescopically interlocking chamber parts locks and in which the Closure of the chamber, causing rotation of the outer chamber that unblocks the bolt, have become known. "With such chamber units, if it is opened, it does not run Reverse rotation the inner chamber into the outer chamber, while with a reverse rotation both chamber parts locked by the locking piece can be pulled out as a whole. the The outer chamber is unblocked from the fixed weapon parts by turning back.

In such chamber units, the bolt handle attached to the outer chamber stands still during the shot, both with single fire and with continuous fire. However -This known constructions have the defect that the striker was tense even before the arrival of the outer chamber in their Verblockungslage, "sö that it could happen that the firing pin has already been accidentally once withdrawn before the outer chamber - blocked the fixed gun parts became.

Avoiding this deficiency is primarily an object of the invention. For this purpose, the locking piece, which, as I said, the two telescope-like interlocking chamber parts interlocked, designed so that it is at the same time with this interlocking, the firing pin is also interlocked. The reverse is the The firing pin is only unblocked when the two chamber parts are also unblocked.

Since with the aforementioned chamber units the unblocking of external and inner chamber at the same time with the blocking of the outer chamber with the fixed Weapon parts takes place, it follows that the subject of the invention of the firing pin is blocked until the outer chamber is blocked with the fixed Gun parts is done. It can then no longer happen that when loading Hand a shot is accidentally released before the outer chamber is in its final position has taken. In order to achieve this result, the locking piece is expedient in the bolt handle, which locks the outer chamber with the fixed weapon parts causes, inevitably led.

It is known per se to block the firing pin until the chamber is completely locked. However, this has not yet been done: with -chamber units of the type described at the outset, which have the advantage, that the already existing locking piece can be used for another function can.

The bolt handle, in which the bolt is guided, can be rotated, but immovably connected to the outer chamber and in the L-shaped Be guided housing groove, in the axially parallel part of the locking piece the outer chamber with the inner chamber and the firing pin and in their circumferential stiffness the chamber handle even the outer chamber rffit. blocked the weapon housing. It consists; ' then Possibility of blocking the inner chamber with the outer chamber in any position of its way, what z. B. when removing jams when shooting automatically as very proves beneficial. Because only the bolt handle, but not the outer chamber needs to be rotated when it is locked to the fixed weapon housing, the operation of the chamber unit is simplified.

Since the inner chamber then no longer rotates either, they are locked to the barrel when loading by turning the locking ring, as is already the case with known weapons.

In the drawings, the subject matter of the invention is in one embodiment shown.

Fig. I shows the chamber unit according to the invention in longitudinal section.

Fig. Z is another longitudinal section, in the direction of arrow A of Fig. I seen in the position in which the inner chamber is already closed is locked, but the outer chamber is not yet blocked with the fixed parts is.

Ab'b.3 is a section in the direction of line B-B of Fig. 2, showing the Shows bolt handle together with its ring in the blocking position.

Fig.4 is a section in the direction of line B-B of Fig. Z showing the Shows bolt handle together with its ring in the release position.

The chamber unit according to the invention consists of the outer chamber m and the telescopic inner chamber o. In the inner chamber is the Firing pin g mounted. The usual procedures are used to fetch and tension these parts Springs provided.

A blocking ring i is screwed onto the outer chamber, from which the bolt handle a protrudes radially. The connection of the bolt handle with the outer chamber about the locking ring i is such that when the bolt handle is moved in the direction of the axis of the soul, the outer chamber is taken along during a rotation but not of the bolt handle.

For movement: the bolt handle is L-shaped in the lock case Groove is provided, the leg p1 of which extends in the circumferential direction from the wall n of the lock case is complete. When twisting the bolt handle vön From the position according to Fig. 4 to that according to Fig. 3, the outer chamber is therefore axially immovable connected to the box, d. H. so blocked. : via locking ring i becomes with the Schloßj ', s-th by a bayonet catch k-Aiogelt.

Bolt handle a is mounted movably in the radial direction, a slide b, which is pressed inward by a spring c. The locking ring i is below of the slide is provided with a recess l so that it can pass through to the inside can. The inner chamber has an opening f and the firing pin with a further opening h provided, both of which are in the direction of the bolt handle, when this has taken its release position (Fig. 4). The slide b can therefore pass through all these parts under the influence of its loading spring c. The slide is provided with flattened sides d for better guidance.

In this position of the slide, the firing pin g is in his held back in the tensioned position and at the same time the inner chamber with the outer chamber locked.

When the bolt handle with the slide b in the position according to Ab-b. 3 moves is, the slide is through the boundary surfaces of the openings in the firing pin and pushed outwards at the parts of the chamber until he is finally in the withdrawn Position is caught by the edge of the housing, which has an opening a1 in the bolt handle jumps into a notch e of the slide. The firing pin is now released and the inner chamber can move freely with respect to the outer chamber.

So it cannot happen that the outer chamber is not yet blocked a shot is fired.

The locking of the inner chamber o with the one not shown here In the illustrated embodiment, the run is carried out by a rotary stud lock, its locking ring q during its longitudinal displacement in the weapon housing by inclined surfaces is rotated and .taking the opposing teeth on the inner chamber or releases. The locking ring leads this movement not only during self-loading under the influence the recoil, but also under the influence of the inner chamber during single loading hand-applied axial movement.

During self-loading it can happen that for some reason the inner chamber stops on its way into the outer chamber. In order to make the weapon ready to fire again, the outer chamber is pulled back by the bolt handle until the opening 1 in the locking ring is above the opening f in the inner chamber and the slide can penetrate it. As a result, the inner and outer chambers are locked together and can be moved together.

Claims (5)

PATENT CLAIMS: i. Chamber unit consisting of inner and outer chambers for self-loading weapons, in which the outer chamber telescopes into the inner chamber pushes in and in which the inner and outer chambers are connected to one another by a locking piece can be blocked or unblocked, characterized in that this locking piece In addition to the aforementioned functions, there is also a known locking of the firing pin causes with the chamber parts. 2. Chamber unit according to claim i, characterized in that that the locking piece in the bolt handle, which locks the outer chamber with the fixed weapon parts takes over, is so inevitably performed that bolt handle and locking piece their interlocking and unblocking take in. 3. Chamber unit according to claim i and 2, characterized in that the bolt handle rotatable but immovable connected to the chamber and in one L-shaped housing groove is guided, in the axially parallel part of the bolt handle guided bolt piece the outer chamber with the inner chamber and the firing pin and in the peripheral part of the bolt handle itself the outer chamber with the weapon housing blocked. q .. Chamber assembly according to Claims 1 to 3, characterized in that the locking piece as a slide which can be moved radially to the axis of the soul in the bolt handle is formed, which when guiding the bolt handle on the axially parallel groove part in corresponding recesses occur in both chamber parts and in the firing pin, while he; when guiding the bolt handle in the peripheral part of the groove from the side walls this recesses is pressed radially outward in its inoperative position. 5.
