Federal Republic of Germany-Förbundsrepubliken Tyskland (DE) G 7339065.5 Proof-Styrkt (71) Mauser-Jagdvaffen GmbH, 7238 Oberndorf / Neckar, Federal Republic of Germany-Förbundsrepubliken Tyskland (DE) (Ober) Porf (N), Rolf Kölblin, OF.,

This invention relates to a chamber lock for a magazine, in particular to a magazine for hunting. a rear piece that rotates to the rear end of the lock, with the hammer lever in one of its two operating positions retaining the axial movement of the striker when the trigger is depressed.

It has long been known to equip military as well as hunting magazine weapons with a chamber lock device.

Likewise, devices for securing such weapons have long been known.

In rifles for military use, the impactor causing the firing of the cartridge is secured to the rear of the lock by a pivoting locking lever which, in the secured position, acts on the impactor or the impactor nut.

DE patent publication 900.426 discloses a safety device which produces the same effect, although it is functionally designed in different ways. This lock comprises a lock lever mounted on the left side of the lock rear, which is likewise provided with a spring-loaded pin mounted on the lock rear. When the lock lever is turned to the lock position, the pin is pushed into the recess in the lock head by the oblique surface at the bottom of the lock lever. Thus, the lock cannot be rotated.

These and similar safety devices have been completely satisfactory for military use. However, they do not meet the requirements for hunting magazines. In such weapons, it is desired to provide additional security, or so-called double security. As far as possible, the safety device must be able to prevent hunting accidents, for example due to a branch hitting a gun in the forest.

The present invention is based on the principle of the above-mentioned wing safety device, and the object of the invention is to further improve these previously known magazine rifle security devices.

According to the invention, this object is achieved in that the locking lever, which is shaped as a relatively flat plate and coaxially with respect to the axis of the weapon, has a slot into which secured rests on a correspondingly shaped fixed abutment surface in the rear piece and only by overcoming the force of the resilient member together with the securing lever can be brought into an unsecured position.

an embodiment of the invention, the elastic member is a compression spring, which is prestressed arranged on one side and the other side varmistinvivun in the latch lever.

A further feature of the invention is that the mating surface in the rear piece is vertical.

A number of advantages are associated with the present invention:

The fuse according to the invention is inherently simple in construction; 3 56444 it consists, in practice, of only a few add-ons which do not present any manufacturing difficulties. Thanks to the locking lever, which is flexible relative to the safety lever, the magazine weapon is optimally secured, and accidents caused by unintentional removal of the safety device and trigger release are virtually impossible. In addition, existing magazine weapons can subsequently be equipped with a safety device according to the invention at negligible cost. To do this, all you have to do is remove the previous rear part of the weapon and replace it with another one with a latch lever according to the invention.

In the accompanying drawing, the invention is shown as an application example. In the drawing, Fig. 1 shows a partial vertical section of the securing device in the securing position, Fig. 2 shows the securing device according to Fig. 1 in the unsecured position, and Fig. 3 shows the securing device according to Fig. 1 seen from above.

As a whole, the rear part marked with reference numeral 1 can be screwed from its thread 1a in a manner known per se and not included in the invention to a - not shown - deck lock device or the like.

On the side of the rear piece 1 - above its longitudinal center line 2 - there is an oblique surface 1b, an associated arcuate surface 1c and a vertical surface 1d.

A securing shaft 3 for securing a nut, not shown, or a percussion nut, is mounted on the rear piece 1 for rotation about a point 4. The locking shaft 3 has a slot, a recess or the like 3b for the locking lever 5, which is substantially parallel to the longitudinal center line 2 of the rear part 1. The latch lever 5 is mounted by means of a bolt 6 so as to pivot relative to the securing shaft 3; a compression spring 7 is pre-tensioned between the securing shaft 3 and the locking lever 5.

To turn the locking lever 3 from the "secured" position (Fig. 1) to the "unsecured" position (Fig. 2), the locking lever 5 must first be pressed down against the resistance of the spring 7 so that the surface 5a of the locking lever 5 comes into contact with the correspondingly shaped surface 3a of the locking lever 3. Fitted in the slot 3b and pivotable on the bolt 6

Claims (3)

56444 4 The locking lever 5 can now be folded up together with the locking lever 3. The surface 5b of the latch lever 5 then rests against the vertical surface 1d belonging to the stern piece. When the safety lever 3 and the locking lever 5 are folded up together, the striker is unsecured and the weapon is therefore ready to fire. When the weapon must be secured after the loading movement, i.e. with the cartridge in the cartridge housing, the locking lever 3 and the locking lever 5 are moved together, turning counterclockwise, to the "secured" position (Fig. 1). When the surface 3c rests against the oblique surface 1b and the load is removed from the spring 7, the surface 5c rests against a correspondingly shaped vertical surface 1d (Fig. 1) and thus locks the impactor via the securing shaft 3 against unintentional operation. A chamber lock, in particular for a magazine rifle for hunting, in which the chamber lock has a rear hinge with a pivotable locking lever and rotatable at the rear end of the lock, the locking lever in one of its two operating positions retaining the perpendicular axial movement the locking lever (3) arranged axially with respect to the axis of the weapon has a slot (3b) into which a latch lever (5) under the action of a resilient member (7), similarly formed as a relatively flat plate and coaxially with respect to the axis of the weapon, is pivotally mounted. ) with the lock secured (Fig. 1) rests on a correspondingly shaped fixed mating surface (1d) in the stern and only by overcoming the force of the resilient member (7) together with the securing lever (3) can be brought into an unsecured position (Fig. 2). A chamber lock according to claim 1, characterized in that the resilient member is a compression spring (7) which, when prestressed, is arranged inside the safety lever (3) on the one hand and the latch lever (5) on the other hand. Chamber lock according to Claim 1, characterized in that the mating surface (Id) in the rear part is vertical.
