Abstract

An emergency stop device for a weapon with a drive for transporting a breech block of the weapon. At least one guide, at least one connecting rod guided in the guide, and at least one lever are provided. When a shot is not being fired, the kinematic system is deactivated. When a shot is being fired, the at least one guide is moved rearwards, and the at least one connecting rod is guided upwards along the guide such that the lever exerts a lever movement, by means of which the transport of the breech block is made possible. The weapon drive has a complete control slide for transporting the breech block of the weapon. A bolt is laterally embedded in the transverse slide, said bolt being integrated below the complete control slide of the drive in a movable manner in the slide.

First claim

What is claimed is:

1 . An emergency stop device for a weapon comprising:
a drive for transporting a breech of the weapon; a kinematic system which is formed by at least one guide with a control curve; at least one connecting rod guided in the at least one guide; and at least one lever, wherein, when a shot is not fired and there is no recoil, the kinematic system is without effect, and wherein, when a shot is fired, the at least one connecting rod is guided along the control curve such that the lever exerts a lever movement.

2 . The emergency stop device as claimed in claim 1 , wherein the drive comprises an overall control slide for transporting the breech of the weapon, said overall control slide having, on its bottom side, a fixed lug and a movable cross slide.

3 . The emergency stop device as claimed in claim 2 , wherein a pin is incorporated into the side of the cross slide, which is integrated movably into the overall control slide of the drive, beneath the latter.

4 . The emergency stop device as claimed in claim 3 , wherein the lever acts on the pin in the cross slide.

5 . The emergency stop device as claimed in claim 2 , wherein the cross slide has a recess.

6 . The emergency stop device as claimed in claim 1 , wherein a driving pin of a connecting rod of the drive is mounted in the connecting rod in a spring-loaded manner.

7 . The emergency stop device as claimed in claim 2 , wherein the movable cross slide has a slope.

8 . A weapon having an emergency stop device as claimed in claim 1 .

9 . The weapon as claimed in claim 8 , wherein slopes or ramps are incorporated into the main weapon housing or into a weapon cradle, said slopes or ramps serving to guide the cross slide and the pin back into their original position.

10 . The weapon as claimed in claim 8 , wherein the drive comprises a drive curve and a connecting rod guided in the drive curve, wherein the drive curve includes the firing cycle of the weapon, the connecting rod, in addition to a connecting rod shaft, comprises a front pin and a rear pin as driving pin, the connecting rod engages with its front pin in the drive curve and is guided therein, and wherein the front pin is connected to a crank which is driven by an external drive, and the driving pin is connected to an overall control slide of the breech of the weapon and acts between the lug, incorporated underneath the overall control slide, and the cross slid.

11 . The weapon as claimed in claim 8 , wherein a connecting rod slide has a groove in which the driving pin is guided, and the connecting rod shaft is articulated at a pivot point that is located behind the driving pin, such that the driving pin is pivoted in the groove in the connecting rod slide during the idle times of the breech.

12 . The weapon as claimed in claim 8 , wherein the drive curve comprises a front region extending transversely to the breech and a region having a radius, said regions defining the idle times of the breech.

13 . The weapon as claimed in claim 12 , wherein the radius is as great as the length of the connecting rod guided in the drive curve.

14 . The weapon as claimed in claim 8 , wherein the drive curve is nonround.
