Definitions

  • the invention relates to a weapon barrel lock for a weapon barrel mounted in a cradle such that it can be moved from a rest position to a return position, comprising a base piece, comprising a locking wedge that can be displaced between a closed and an open position, which is displaceable by a locking lever connected to an opener shaft and a the cradle attached plunger.
  • the wedge lock has a lock wedge which can be opened downwards perpendicular to the barrel axis of the weapon barrel.
  • the DE 10 2009 037 899 A1 discloses a wedge lock for a barrel weapon with a base piece connected to the rear of the weapon barrel.
  • the wedge lock has several locking devices that hold the lock wedge in an open position when loading the weapon.
  • the locking wedge remains in its open position as long as a piecer for loading a cartridge holds the locking devices in a position that locks the wedge lock.
  • each a barrel weapon with a barrel lock which have a wedge lock.
  • the wedge lock has a base piece and a locking wedge that opens via a locking mechanism. and is lockable.
  • a spring-loaded control unit is arranged on the cradle with movable elements which actuate the locking mechanism on the base piece when the base piece has advanced so far after a shot that these elements come into contact.
  • the already known gun barrel closures have an opener lever or a closer lever for manual opening and closing apart from a shot, which are to be actuated separately.
  • the invention is based on the object of creating a weapon barrel lock which automatically locks in the open position.
  • a weapon barrel closure for a weapon barrel mounted in a cradle such that it can be displaced from a rest position into a return position.
  • the barrel lock comprises a base piece, a locking wedge which can be displaced between a closed and an open position and which is displaceable by a locking lever connected to an opening shaft, and a plunger attached to the cradle.
  • the barrel lock has a stop coupling which is connected to the opening shaft and which is in contact with the plunger when the locking wedge is in the closed position.
  • a barrel weapon with a cradle and a weapon barrel mounted in the cradle such that it can be moved from a rest position to a return position comprising at least one such barrel lock or a barrel lock that is further developed as described below.
  • the cradle can comprise a cradle tube on which a trunnion and a mounting plate are arranged.
  • the overrun coupling and tappet are designed in this way. That the opening process can take place in any section of the advance and that the advance movement of the returning mass of the barrel weapon is not blocked in spite of the cradle-proof plunger.
  • the plunger can be displaced with respect to the stop coupling in the direction of the weapon barrel axis, whereby the stop coupling can be unlocked from the plunger and the locking wedge can be unlocked in its closed position.
  • the end of the plunger interacts with the overrun coupling so that it is moved, rotates around its axis and opens the locking wedge.
  • the weapon advance should be used to open the wedge, since there is enough energy and high performance available.
  • stop coupling is rotatably mounted and, in a position unlocked by the tappet, can be actuated by the tappet to open the locking wedge.
  • a plunger front can be contacted with the overrun coupling and the overrun coupling can be displaced by the plunger in the direction of the weapon barrel axis.
  • the stop coupling is guided by a guide part for opening the locking wedge.
  • the guide part has a guide curve along which the overrun coupling is forcibly guided in order to open the locking wedge.
  • the plunger and the guide component are arranged such that they can be displaced relative to one another, the plunger being arranged such that it can be pushed into the guide component.
  • the opening of the barrel closure is thus realized by the plunger which is attached to the cradle.
  • the ram hits parts of a wedge opening mechanism in advance.
  • the stop coupling is connected to a wedge-closing spring which pretensions the stop coupling with respect to the plunger.
  • the locking wedge is caught in the open position via the ejector lever.
  • the closing of the breech block is realized by loading a cartridge during continuous shooting. The edge of the case base is pressed against the ejector lever during loading, so that it releases the lock and the locking wedge is closed.
  • the weapon barrel lock has an opening lever connected to the opening shaft in a rotationally fixed manner.
  • the overrun coupling is rotatably mounted on the opening lever, so that the wedge closing spring biases the locking wedge in the direction of its closed position.
  • the locking wedge is opened and closed by turning the opening shaft.
  • the wedge closing spring on the one hand biases the closing wedge in the direction of its closed position. If the locking wedge is in its open position or in an intermediate position between the open and closed position, the locking wedge is pretensioned in the direction of the closed position of the locking wedge by the wedge closing spring.
  • the provision of the wedge locking spring ensures that the locking wedge is caught in its open position after opening, e.g. is caught by the ejector lever.
  • the wedge locking spring biases the coupling towards the closed position.
  • the weapon barrel lock has a drive attached to the cradle which is designed to adjust the position of the plunger in the direction of the weapon barrel axis.
  • the drive is cradle-proof so that the shock loads and the high return accelerations do not affect the drive.
  • the provision of the drive allows intermediate positions for opening the locking wedge to be approached. Because the drive interacts with the ram, the position of the ram in the direction of the weapon barrel axis can be adjusted by the drive.
  • the tappet is arranged within a sliding sleeve connected to the drive and is pretensioned by a tappet spring arranged in the sliding sleeve.
  • the fact that the plunger with the pretensioned plunger spring is provided in the sliding sleeve means that when a predetermined force is exceeded, the plunger can spring into the sliding sleeve and damage can be prevented.
  • suspension of the plunger in relation to the drive ensures that the maximum forces of the drive are limited and that weaker drives can also be used.
  • the sliding sleeve is mounted displaceably in the direction of the weapon barrel axis in a guide tube connected to the cradle.
  • a linearly displaceable drive shaft of the drive is arranged parallel to the plunger.
  • a linearly displaceable drive shaft of the drive is arranged coaxially with at least part of the plunger. It can be provided here that parts of the drive are provided within the guide tube.
  • the barrel lock has an ejector release which is connected to a wedge closer shaft and can be actuated via the plunger.
  • the ram locks and actuates the overrun coupling to unlock and open the locking wedge and, on the other hand, the ram actuates the ejector release.
  • the ram can have a ramp that interacts with the ejector release.
  • the drive is arranged in such a way that it can be decoupled from the plunger when the weapon is returned. This ensures that intermediate positions of the drive for actuating the lock, intentionally or unintentionally, for example due to errors, do not lead to dangerous operating states or to damage to the barrel lock.
  • the plunger is set up to actuate the overrun coupling in a state unlocked by the plunger in order to unlock the wedge lock in its closed position.
  • Fig. 1 shows a weapon barrel closure 10 for a weapon barrel mounted in a cradle 40 such that it can be displaced from a rest position into a return position.
