Abstract

A breech ammunition drive for the breech of a weapon using an external drive is provided. A long connecting rod converts the rotational movement into a linear breech movement, and a short connecting rod moves the breech. The rear end or pin of the long connecting rod is fixed on or in the drive, and the front end engages onto a rack that is fixed to the weapon and onto a slider of the breech support or the breech via a toothing. The short connecting rod is retained in the slider and guided by same, and the connecting rod engages into a transverse slot introduced above the connecting rod and below the breech support. The short connecting rod is guided in the slot fixed to the weapon, the slot having a rear end point into which the connecting rod is inserted.

Claims

1. A breechblock feed for a breechblock of a weapon, comprising

a drive;

and

a long connecting rod and a short connecting rod being integrated functionally connected to the drive, the long connecting rod being fastened at a back end thereof or pinned in the drive and at a front end engages via toothing with a rack, which is fixed with respect to the weapon, and with a slider of a breechblock support or the breechblock, the short connecting rod being held in and guided by the slider and also engages in a transverse slot introduced above the connecting rod and below the breechblock support.

2. The breechblock feed according to claim 1, wherein the short connecting rod is guided in the slot that is fixed with respect to the weapon, which slot has a rear end point into which the connecting rod is pushed.

3. The breechblock feed according to claim 2, wherein the short connecting rod is pivotable in the rear end position in the end point of the slot.

4. The breechblock feed according to claim 1, wherein the breechblock support and the breechblock are structurally connected to one another by a carrier that is functionally attached in a fixed manner to the breechblock.

5. The breechblock feed according to claim 4, wherein the locking of the breechblock is achieved via an additional locking slot integrated into the breechblock support, into which the carrier is adapted to escape for locking.

6. The breechblock feed according to claim 5, wherein the locking slot has a locking path via which a floating support that accommodates the reverse motion of the breechblock is achieved in the firing position.

7. The breechblock feed according to claim 1, wherein the drive is a disk.

8. The breechblock feed according to claim 7, wherein the drive has an external toothing.

9. The breechblock feed according to claim 7, wherein the long connecting rod serves to convert the rotary motion into a linear breechblock motion, and the short connecting rod serves to move the breechblock or the breechblock support.

10. A weapon comprising:

a breechblock feed according to claim 1; and

a rear-locking breechblock.

11. The breechblock feed according to claim 1, wherein the breechblock feed is a rear-locking breechblock.
