Abstract

A rifle has a shoulder support and at least one barrel connected to the shoulder support. A trigger is provided and a chamber is arranged behind the trigger when looking in a direction from a front end of the barrel toward the shoulder support. A movable breechblock has a closed position in which the chamber is closed off. At least one firing pin for firing a cartridge inserted into the chamber when the trigger is triggered is provided. A coupling mechanism connects the shoulder support or a swivel arm to the breechblock. The breechblock is movable by a pivot movement of the shoulder support or the swivel arm transmitted by the coupling mechanism. An axis of rotation of the shoulder support or the swivel arm is arranged within a space delimited by the breechblock and the trigger viewed across a length of the rifle.

Claims

1. A rifle comprising:

a shoulder support;

at least one barrel connected to the shoulder support;

a trigger;

a chamber arranged behind the trigger when looking in a direction from a front end of the at least one barrel toward the shoulder support;

a movable breechblock having a closed position in which the chamber is closed off;

at least one firing pin for firing a cartridge inserted into the chamber when the trigger is triggered;

a coupling mechanism connecting at least one of the shoulder support and a swivel arm to the breechblock, wherein the breechblock is movable by a pivot movement of at least one the shoulder support and the swivel arm transmitted by the coupling mechanism onto the breechblock; and

wherein an axis of rotation of at least one of the shoulder support and the swivel arm is arranged within a space delimited by the breechblock and the trigger when viewed across a length of the rifle.

2. The rifle according to claim 1, comprising two of the at least one barrel arranged over and under and defining a top barrel and a bottom barrel.

3. The rifle according to claim 2, wherein the breechblock is a unit closing off the chamber of the two barrels, respectively.

4. The rifle according to claim 2, wherein the breechblock comprises a movable block for blocking a transmission of a movement of a trigger bolt of the trigger, caused by triggering the trigger, onto the at least one firing pin.

5. The rifle according to claim 2, wherein the trigger comprises a trigger mechanism connected to a frame that is connected to one of the two barrels.

6. The rifle according to claim 5, wherein the frame is connected fixedly to the top barrel or the bottom barrel and has a passage through which the bottom barrel passes when the frame is attached to the top barrel and through which the top barrel passes when the frame is attached to the bottom barrel.

7. The rifle according to claim 2, comprising a switching mechanism with a rocker for alternatingly switching transmission of an action of the trigger onto the at least one firing pin of the top barrel or the bottom barrel.

8. The rifle according to claim 1, comprising a guide for the breechblock.

9. The rifle according to claim 1, wherein a section of the guide where the guide supports the breechblock in the closed position engages the breechblock positively for receiving explosion forces from the at least one barrel.

10. The rifle according to claim 1, wherein the breechblock comprises a mechanism for actuating the at least one firing pin.

11. The rifle according to claim 1, wherein the breechblock is moveable in a direction substantially perpendicular to a longitudinal direction of the at least one barrel.

12. The rifle according to claim 1, wherein, in a firing position of the rifle, the axis of rotation is substantially horizontal and the breechblock is moveable in a substantially vertical direction.

13. The rifle according to claim 1, wherein the trigger is arranged within a central third of a length of the at least one barrel.

14. The rifle according to claim 1, wherein a triggering movement of the trigger is transmitted onto the at least one firing pin only in the closed position of the breechblock.

15. The rifle according to claim 1, further comprising an ejector, wherein the coupling mechanism comprises coupling elements connected to the ejector such that a swivel movement of the shoulder support causes the ejector to be driven.

16. The rifle according to claim 1, further comprising at least one storage device for ammunition or small parts, wherein the at least one storage device is provided in or on a stock of the rifle or the shoulder support.

17. The rifle according to claim 16, wherein the at least one storage device is detachable.
