EP2561303B1 - Weapon with barrel having a wedge-type breech locking mechanism - Google Patents

Description

The invention relates to a gun barrel with a weapon tube slidably mounted in a cradle tube from a rest position to a return position with bottom piece, wherein the bottom piece comprises a wedge lock with a transverse to the soul tube axis of the barrel from a closed to an open position by means of a Öffnerhebels slidable sealing wedge.

Such a gun is, for example, from the document DE 103 17 177 A1 known. In this known barrel weapon, a holding arm extending axially to the bottom piece of the gun is provided on the cradle tube, to which a guide means is attached. In this case, the length of the holding arm is selected such that the guide device is arranged in the rest position of the gun barrel laterally on the bottom piece, so that at a return of the gun barrel (after firing) from its return position to its rest position with the opener lever (or an opener shaft) the wedge closure connected peg-shaped carrier is supported on the guide device and causes a rotation of the opener lever and thus an opening of the closure wedge.

A disadvantage of this known tube weapon, inter alia, that a relatively wide-extending support arm for the guide device is required to operate the arranged on the opening lever driver intended. This is associated with a high weight of the holding arm and a large space requirement for the gun. In addition, the opening of the shutter long back and flow paths are required so that corresponding large return spaces behind the weapon are required.

Starting from the DE 103 17 177 A1 The invention has for its object to provide a gun barrel, are avoided in the wide-spreading and thus heavy holding arms for the guide means of the peg-shaped driver for actuating the closure wedge.

This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

The invention is based essentially on the idea to provide for controlling the shutter movement on the bottom piece from an initial to an actuating position axially displaceable push rod which acts on its side facing away from the cradle on the connected to the shutter wedge opening lever, and on their the Cradle tube facing side is connected via a lever mechanism with the driver, which is supported during the return of the gun barrel on the control contour (control curve) of a guide tube attached to the cradle tube.

In a preferred embodiment of the invention for realizing the invention, the displaceable push rod is arranged in a bottom-fixed guide member which projects axially on its side facing the cradle tube slightly in front of the bottom piece. In this case, the push rod is axially connected on its end facing the cradle tube via a sliding joint with the first end of a coupling member. The second end of the coupling member is connected via a first pivot with a rocker whose first end is pivotally mounted at the weigh tube end of the guide member in a second pivot and the second end carries the itself supported on the control cam of the guide means driver.

Since the rocker with driver is located on the cradle tube side in front of the bottom piece, (unlike in the case of DE 103 17 177 A1 ) are dispensed with a longer support arm for the guide device.

The guide member may preferably also be at least partially integrated directly into the bottom piece. For example, the push rod can be performed in a hole directly in the bottom piece.

In one embodiment of the invention, the first hinge is arranged approximately in the central region between the second pivot and the catch of the rocker. Of course, the arrangement of the first pivot on the rocker can also be chosen differently if the axial displacement of the push rod for opening the closure wedge requires this. Such is the axial displacement of the push rod the larger, the closer the first pivot is located at the second end of the rocker.

Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:

In Fig. 1 is denoted by 1 a gun barrel according to the invention with a in a cradle tube 2 a cradle slidably mounted from a rest position to a return position gun barrel 3, wherein in Fig. 1 the return position of the gun barrel 3 is shown.

The weapon barrel 3 comprises at the rear a bottom piece 4 with a lifting wedge closure 5 which contains a transversal wedge 7 which can be displaced transversely to the tube axis 6 of the weapon barrel 3 from a closed to an open position.

At the bottom piece 4, a push rod 8, which is axially displaceable from an initial position into an actuating position, is arranged in a guide element 9 which is fixed to the floor ( Fig. 2 ), which on the side facing away from the viewer of the bottom piece 4 or on the viewer side facing the bottom piece 4 (Fig. Fig. 3 ) can be attached. The attachment can be done via mounting holes 24 and 25 by means of a feather key. The push rod 8 acts on its side facing away from the cradle tube 2 or on a connected to the closure wedge 7 opening lever 10, such that a displacement of the push rod 8 to the closure wedge 7 towards a pivoting movement of the opening lever 10 and thus to an opening of the closure wedge. 7 leads.

For actuating the opener lever 10, the push rod 8 is formed on its side facing the opener lever 10 or side facing away as a rack, and the guide member 9 has a recess 11, via which a connected to the opening lever 10 gear (not shown) engages the rack ,

As Fig. 1 Removable, the guide member 9 projects axially on its side facing the cradle tube 2 slightly in front of the bottom piece. 4

The push rod 8 is connected on its end facing away from the cradle tube 2 via a sliding joint 12 with the first end 13 of a fork-shaped coupling member 14, the second end 15 is connected via a first pivot 16 with a rocker 17 ( FIGS. 2 and 3 ). In this case, the first end 18 of the rocker 17 is pivotally mounted on the weigh tube end of the guide member 9 in a second pivot 19. At the second end 20 of the rocker 17, a cam-shaped driver 21 is arranged. Like that Fig. 1 and 2 removed, in the illustrated embodiment, the first pivot 16 is disposed approximately in the central region between the first and second ends 18, 20 of the rocker 17.

On the cradle tube 2 is located on the bottom piece 4 side facing a guide device 22 with a cam 23rd

Below will be discussed in more detail on the operation of the gun barrel 1 according to the invention. It may be the gun barrel 3 (after firing) in his in Fig. 1 be shown return position. In this position, the shutter wedge 7 initially remains closed, the push rod 8 and the existing of the rocker 17 and the coupling member 14 lever mechanism remain in the in Fig. 2 illustrated starting position.

From this return position, the gun barrel 3 is moved with bottom piece 4 by a pipe recuperator, not shown, to the cradle tube 2, which in Fig. 1 through a Arrow 100 is indicated. In this case, the cam-shaped driver 21 comes to the control cam 23 of the attached to the cradle tube 2 guide means 22 and slides on the corresponding control contour along ( Fig. 3 ).

As a result, the rocker 17 is pivoted clockwise about the passing through the second pivot 19 axis of rotation and causes the coupling member 14 a displacement of the push rod 8 against the weft direction along the guide member 9, so that the opener lever 10 is pivoted and the shutter wedge 7 is moved to its open position becomes. In this position, the cartridge case of the fired cartridge is then ejected by means of corresponding cartridge ejector (not shown).

After the driver 21 has passed the control cam 23, the wedge lock 5 initially closes until it reaches a loading position and is held in this position by the cartridge ejectors arranged on the closure side.

The gun 1 can now be reloaded. The cartridge ejectors are pivoted when inserting the cartridge in the bottom piece 4 and release the shutter wedge 7 so that it is moved to its closed position. The barrel weapon 1 is ready to fire.

Of course, the invention is not limited to the embodiment described above. So can the in the FIGS. 2 and 3 shown control curve 23 may be arranged, for example, instead of a horizontal plane in a vertical plane. In this case, the rocker 17 must be pivotally mounted on the guide member 9, that their pivotal movement is also in a vertical plane.

Furthermore, the opener lever does not necessarily have to be designed as a lever which acts on an opener shaft connected to the closure wedge, as in FIG Fig. 1 is indicated, but it can also be a gear or sprocket part in the opening lever, which is mounted on the opener shaft.
