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. Thus, the closer the first pivot is located at the second end of the rocker, the greater the axial displacement of the push rod.

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

1 a side view of the rear-end portion of a movable in a cradle barrel with bottom piece, the gun barrel is in its return position and in the bottom piece a Hubkeilverschluss is arranged, which connected to a bottom piece side lever mechanism for opening the shutter wedge in the movement of the gun barrel in its rest position is;

2 a schematic perspective view of the in 1 arranged on the gun barrel lever mechanism with a driver before it reaches a arranged on the pipe cradle guide device and

3 a 2 corresponding view after the driver of the lever mechanism has reached the guide device and is supported on a control cam of the guide device.

In 1 is with 1 a gun according to the invention with one in a cradle tube 2 a tubular cradle from a rest position to a return position slidably mounted barrel 3 denotes, in 1 the return position of the weapon barrel 3 is shown.

The gun barrel 3 includes a bottom piece at the rear 4 with lifting wedge closure 5 , the one across to the soul tube axis 6 of the barrel 3 from a closed to an open position sliding shutter wedge 7 contains.

At the bottom piece 4 is a push rod axially displaceable from an initial to an actuated position 8th in a bottom-fixed guide part 9 arranged ( 2 ), which on the side facing away from the viewer of the bottom piece 4 or on the viewer facing side of the bottom piece 4 ( 3 ) can be attached. The attachment can via mounting holes 24 and with the help of a feather key 25 respectively. The push rod 8th acts on her the cradle tube 2 off or facing side on one with the closure wedge 7 connected opening lever 10 , such that a displacement of the push rod 8th to the lock 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 is the push rod 8th on her the opener lever 10 side facing away from or designed as a rack, and the guide member 9 has a recess 11 on, over which one with the opening lever 10 connected gear (not shown) engages the rack.

As 1 removable, protrudes the guide part 9 on his the cradle tube 2 axially facing slightly before the bottom piece 4 ,

The push rod 8th is on her the cradle tube 2 facing or opposite end via a sliding joint 12 with the first end 13 a fork-shaped coupling member 14 connected, its second end 15 over a first hinge 16 with a swingarm 17 connected is ( 2 and 3 ). This is the first end 18 the swingarm 17 at the weigh tube end of the guide member 9 in a second pivot 19 pivoted. At the second end 20 the swingarm 17 is a cam-shaped driver 21 arranged. Like that 1 and 2 removed, is in the illustrated embodiment, the first hinge 16 approximately in the middle region between the first and second end 18 . 20 the swingarm 17 arranged.

At the cradle tube 2 is located on the bottom piece 4 side facing a guide device 22 with a control curve 23 ,

The following will be closer to the operation of the gun according to the invention 1 received. Thereby may the weapon barrel 3 (after firing) in his in 1 be shown return position. In this position, the shutter wedge remains 7 first closed, the push rod 8th as well as from the swingarm 17 and the coupling member 14 existing lever mechanism remain in the in 2 illustrated starting position.

From this return position becomes the weapon barrel 3 with bottom piece 4 by a pipe recuperator, not shown, to the weighing tube 2 postponed what was in 1 through an arrow 100 is indicated. Here comes the cam-shaped driver 21 to the control curve 23 the on the cradle tube 2 attached guide device 22 and slides along the corresponding control contour ( 3 ).

This will make the swingarm 17 clockwise around the second pivot 19 going axis of rotation pivots and causes via the coupling member 14 a shift of the push rod 8th against the weft direction along the guide part 9 so the opener lever 10 panned and the shutter wedge 7 is moved to its open position. 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 at the control curve 23 has passed, the wedge lock closes 5 initially until reaching a loading position and is held in this position by the closure side arranged cartridge ejectors.

The barrel weapon 1 can now be reloaded. The cartridge ejectors are when inserting the cartridge in the bottom piece 4 pivoted and give the shutter wedge 7 free, 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 2 and 3 illustrated cam 23 for example, be arranged in a vertical plane instead of in a horizontal plane. In this case, the swingarm needs 17 such on the guide part 9 be pivotally mounted so 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 1 is indicated, but it can also be a gear or sprocket part in the opening lever, which is mounted on the opener shaft.
