Definitions

  • the invention relates to a tube weapon with a front tube piece which can be tilted by means of an actuating device about a shield pin, and with a rear tube piece which can also be pivoted about the shield pin, the tube pieces in their coaxial position by means of a sealing ring at a separation point without an axial Moving one of the pipe pieces are sealed.
  • Such a gun is described in DE-OS 34 40 467.
  • the front barrel section is pivoted into a horizontal position relative to the rear barrel section.
  • the front pipe section is pivoted in front of the rear pipe section.
  • the ammunition then falls on a striking pin of the rear pipe section.
  • This barrel weapon is suitable as a firearm.
  • the elevation angle is adjusted by swiveling the two pipe sections together around the shield spigot.
  • DE-OS 22 38 345 describes a grenade launcher in which the front pipe section, pivoted away from the rear pipe section, can be loaded from below. In order to seal the two pipe sections at the point of separation, the front pipe section is pushed axially onto the rear pipe section. This is done with the same actuating device with which the front pipe section can be tilted. A locking sleeve is provided to lock the two pipe pieces.
  • the object of the invention is to propose a tube weapon of the type mentioned, in which the sealing of the tube pieces is improved.
  • the above object is achieved in the case of a tubular weapon of the type mentioned at the outset in that a closure sleeve is provided which is guided on a thread, and in that in the coaxial position of the tube pieces the actuating device rotates the closure sleeve, which rotates together with that arranged in it Axial sealing ring pushes over the separation point of the pipe sections.
  • the sealing sleeve pushed over the separation point ensures the coaxial alignment of the pipe sections, which is a prerequisite for a secure seal.
  • the sealing ring pushed by the breech over the separation point prevents gas escaping when the shot is fired.
  • the sealing sleeve does not axially lock the pipe sections against one another.
  • the rear tube is guided axially in the tube holder.
  • Another advantage of the invention is that, with the same actuating device with which the front pipe section can be tilted, the closure sleeve is pushed over the separation point by its thread guide.
  • the thread on which the closure sleeve is guided is preferably arranged on the rear pipe section and the closure sleeve pushes the sealing ring over the front pipe section.
  • the thread itself contributes to the sealing.
  • the sealing sleeve is pushed forward, the Separation point of the two pipe sections between the thread and the sealing ring.
  • this has a toothed ring, into which a first toothed gear engages, which can be driven by the actuating device. This allows the locking sleeve to be rotated by a simple pivoting lever of the actuating device.
  • the actuating device has a second toothed gear with which the front tube piece can be tilted.
  • the first toothed gear is locked when the second toothed gear is active.
  • the second gear is locked when the first gear is in effect. This ensures that the closure sleeve is not moved until the pipe pieces are aligned coaxially. On the other hand, this also ensures that when the actuating device is actuated in reverse, the closure sleeve is first withdrawn and then the front tube piece is tilted.
  • an ammunition stop is arranged in the front pipe section, which pivots towards the end of the displacement of the closure sleeve over the separation point of the pipe sections from the front pipe section. This ensures that the ammunition only slides into the rear pipe section and is fired when the seal has been made.
  • the closure sleeve preferably pivots the ammunition stop over the push rod even when it is pushed forward over the separation point from the front pipe section. This makes it unnecessary to provide a special coupling between the actuating device and the ammunition stop.
  • the actuating device has a latching device which blocks the actuating device after the closure sleeve has been pushed forward.
  • the latching device prevents the actuating device from being able to be actuated in the opposite direction after the ammunition has slid into the rear tube piece.
  • the locking device is triggered after the ammunition has been completed. The locking device can be released manually or by the gas pressure of the shot.
  • a barrel weapon is mounted on a carrier (1), for example in a vehicle.
  • the barrel weapon is mounted on a shield pin (2) so that it can pivot about an elevation axis (A).
  • the barrel weapon has a front barrel section (3) and a rear barrel section (4). Both pipe sections (3, 4) are pivotably arranged on the shield pin (2).
  • the front pipe section (3) can be pivoted around the shield pin (2) by means of an actuating device (5) shown in FIGS. 2 to 4 relative to the rear pipe section (4).
  • An adjusting device (6) engages on the rear pipe section (4), with which the elevation angle of the rear pipe section (4) can be adjusted.
  • the rear pipe section (4) has a base part (7) which is guided on a slide rail (8) and is provided with a firing pin (9).
  • the front pipe section (3) is pivoted into a horizontal position relative to the rear pipe section (4). It is coaxial with a charging cradle (10) from which an ammunition (11) can be inserted into the front pipe section (3).
  • a head stop (12) is provided to prevent the ammunition from being pushed out of the front tube section (3).
  • the stop (13) displaced by the inserted floor snaps behind the floor at the end of the stroke and secures it against premature sliding.
  • the rear pipe section (4) sits in a pipe holder (14) which is pivotally mounted on the shield pin (2).
  • a thread (15) is formed on the rear pipe section (4), on which a closure sleeve (16) with an internal thread (17) is guided.
  • a sealing ring (19) is inserted on the closure sleeve (16) by means of a cap (18).
  • the closure sleeve (16) is provided on the outside with a ring gear (20).
  • a pinion (21) of a first toothed gear (22) engages in the ring gear (20) and can be driven by a toothed segment (23) which can be pivoted about an axis (24).
  • a wheel (25) of the actuating device (5) interacts with the toothed segment (23), on which a manually operable pivot lever (26) is attached.
  • a second toothed segment (27) also interacts with the wheel (25) as a second toothed gear, which can be pivoted about the cutting pin (2) to which the front pipe section (13) is attached.
  • the wheel (25) has tooth gaps (28) for teeth (29) of the toothed segment (23).
  • the wheel (25) also has tooth gaps (30) for engaging teeth (31) of the second tooth segment (27).
  • the wheel (25) is provided with a locking surface (32).
  • This locking tabs (33) of the toothed segment (23) and locking lugs (34) of the toothed segment (27) are assigned.
  • the locking surfaces (32) and the locking lugs (33, 34) on the one hand and the tooth gaps (28, 30) and the teeth (29, 31) lie in different parallel planes.
  • Two steps (35, 36) are provided on the toothed segment (23).
  • a latch (37) is assigned to these.
  • the latch (37) is under the action of a tension spring (38).
  • the latch (37) can be lifted off the steps (35, 36) by means of a handle member (39).
  • An ammunition stop (13) (40) is pivotally mounted about an axis (41) on the front pipe section (3).
  • a push rod (43) which is loaded by a spring (44), engages on a pin (42) of the stop member (40).
  • the pull rod (43) is connected to a slide (45) which can be acted upon by the cap (18) of the closure sleeve (16) (cf. FIG. 4).
  • the teeth (31) of the second tooth segment (27) engage in the tooth gaps (30).
  • the locking lugs (33) of the toothed segment (23) rest on the locking surface (32).
  • the latch (37) rests on the head of the tooth (29).
  • the swivel lever (26) is actuated clockwise (U).
  • the front pipe section (4) is pivoted via the engagement of the teeth (31) in the tooth gaps (30).
  • the locking lugs (33) of the toothed segment (23) slide on the locking surface (32), so that the toothed segment (23) does not move and the closure sleeve (16) thus also stands still.
  • the latch (37) must be released from the step (36) by means of the handle member (39). Then you can counteract by moving the pivot lever (26) clockwise (U) the front pipe section (3) can be moved into its loading position.
  • the closure sleeve (16) is withdrawn via the separation point between the two pipe sections (3, 4) because the teeth (29) engage in the tooth gaps (28) so that the closure sleeve (16) on the thread (15) is turned back .
  • the stop member (13) is brought back into the position by means of the spring (44) in which it does not allow ammunition (11) to fall out directly into the rear pipe section (4). Then the teeth (31) engage in the tooth gaps (30) so that the front pipe section (3) is tipped over from the rear pipe section (4).
