Definitions

  • the invention relates to a gun barrel with a weapon tube slidably mounted in a cradle 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 sliding closure wedge.
  • Such a gun is known for example from the document DE 101 46 423 A1.
  • To automatically open the shutter wedge in this gun after a firing shot, so that the cartridge case ejected by an ejector and then a new cartridge can be reloaded acts on the bottom piece of an output into an actuating position axially displaceable piston rod via intermediate links on with the Closing wedge connected opener lever, such that a displacement of the piston rod to the wedge closure leads to a pivoting movement of the opener lever and thus to an opening of the closure wedge.
  • the piston rod and a parallel to the piston rod attached to the bottom piece of control via a arranged on the cradle control unit in operative connection such that in a flow of the barrel from its return to its rest position, the piston rod moved by the control unit and thus the Closure wedge is brought into its open position.
  • the control unit comprises a fixed to the cradle of the gun barrel housing which encloses a against the pressure of a first spring axially displaceable towards the mouth of the gun barrel and aligned with the piston rod shift rod, and at least one of the control via a control rod from a locking position in a release position operable, pivotable locking element, wherein the locking element engages positively in its locking position in a locking groove of the shift rod.
  • the countries gene of the piston rod and the shift rod chosen such that the closure wedge has already moved in the lead of the gun barrel by the axial displacement of these rods in its open position before the control acts on the control rod and thus before the locking element passes into its release position.
  • the invention has the object to provide a gun barrel, in which the control unit for actuating the force acting on the opening lever piston rod has a more compact structure, as this is the case with the known gun barrel.
  • the bottom piece includes a wedge lock with a transversely to the soul tube axis of the barrel from a closed to an open position sliding closure wedge.
  • axially displaceable piston rod is arranged, which protrudes axially in its initial position on its side facing the cradle axially in front of the bottom piece and which acts on its side facing away from the cradle via intermediate members on an opener lever connected to the closure wedge ,
  • a displacement of the piston rod to the closure wedge leads to a pivoting movement of the opener lever and thus to an opening of the closure wedge.
  • a rod-shaped control element is fixedly arranged parallel to the piston rod at the bottom piece, wherein the piston rod and the control element are operatively connected via a control unit arranged on the cradle, such that the piston rod of., Is returned to its rest position when the weapon barrel advances the control unit (11) moved and thus the shutter wedge is moved to its open position.
  • the control unit comprises a housing attached to the cradle, which encloses a, for example, against the pressure of a first spring axially displaceable towards the mouth of the gun barrel and aligned with the piston rod shift rod, and at least one actuatable by the control of a locking position in a release position latching element, wherein the locking element engages in its blocking position in a locking groove of the shift rod.
  • the lengths of the piston rod and the shift rod are chosen such that the Closing wedge has already moved in the forward flow of the gun barrel by the axial displacement of these rods in its open position, before the control actuates the locking element in its release position,
  • the invention is based essentially on the idea to replace the control rod and the pivotable locking element of the known control unit by a on the housing of the control unit against the pressure of a second spring axially displaceably arranged control sleeve whose inner wall portion has a control contour on which in the latching elements mounted radially displaceably on the wall region of the housing in guide recesses are supported on the outside.
  • a plurality of ball-shaped or cylindrical locking elements are provided, which are each mounted radially displaceably in a separate guide recess of the housing surrounding the switching rod, and engage in their respective locking position in a ring around the shift rod around running locking groove.
  • control sleeve with its bottom piece of the gun barrel end facing axially displaceable on the closure side protruding from the housing shift rod and its cradle end axially slidably mounted on a tubular housing part of the housing.
  • the inner wall region of the control sleeve forming the control contour can be formed, for example, by a substantially conical wall section widening in the direction of the bottom piece.
  • the bottom of the gun barrel facing away from the housing base of the control unit axially slidably mounted in the cradle Housing part stored and operable from the outside.
  • Figure 1 is a side view of the closure-side region of a gun located in the firing position invention with Hubkeilver gleich, cradle tube and control unit.
  • FIG. 2 shows an enlarged longitudinal section through the control unit shown in FIG. 1;
  • FIG 3 shows the side view of the gun shown in Figure 1 in the maximum return position of the gun barrel with a closed closure.
  • FIG. 4 shows an enlarged longitudinal section through the control unit shown in FIG. 3;
  • Fig. 5 is a side view of the gun shown in Fig. 1 with open shutter wedge and
  • Fig. 6 is a side view of the gun shown in Fig. 1 with befindlichem in loading position open shutter wedge.
  • Fig. 1 the closure-side region of a gun barrel according to the invention with 1 in a cradle tube 2 from a rest position to a return position slidably mounted barrel 3 is designated.
  • 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.
  • a piston rod 8 which is axially displaceable from an initial position to an actuating position, is arranged, which in its initial position protrudes axially in front of the bottom piece 4 on its side facing the cradle tube 2 (FIG. 3) and on their side facing away from the cradle tube 2 via intermediate members, not shown, acts on an opener lever 9 connected to the closing wedge 7, such that a displacement of the piston rod 8 towards the wedge 7 leads to a pivoting movement of the opening lever 9 and thus to an opening of the closure wedge 7.
  • a rod-shaped control element 10 is also fixedly arranged parallel to the piston rod 8.
  • the piston rod 8 and the control element 10 are connected via a arranged on the cradle tube 2 control unit 11 in operative connection, the structure of Figs. 2 and 4 show and their function will be explained in more detail below.
  • the control unit 11 comprises a housing 12, which essentially consists of a tubular housing part 13 fastened to the cradle tube 2 and a housing floor 14 closing the housing part 13 on the side facing away from the floor piece 4.
  • the tubular housing part 13 encloses partially against the pressure of a first (pressure) spring 15 axially displaceable towards the mouth of the gun barrel 3 and aligned with the piston rod 8 shift rod 16.
  • the piston rod 8 facing end 17 protrudes from the front side of the tubular housing part and is connected via a shock absorber 18 with the remaining part of the shift rod 16.
  • the first spring 15 is supported on its side facing away from the shift rod 16 on the housing bottom 14.
  • a plurality of spherical locking elements 19 are provided on the cradle-fixed housing part 13, which are mounted radially displaceable in attackssaus strictly adopted (holes) 20 of the tubular housing part 13, wherein the holes 20 are arranged distributed uniformly over the circumference of the housing part 13.
  • a control sleeve 21 which is axially displaceable on the cradle-fixed housing part 13 of the control unit 11, is provided with a control wall 22 having an inner wall region 23.
  • the control sleeve 21 is pressed against the pressure of a second spring 24 from a rest position in which the locking elements 19 acted upon by the control contour 22 in an annular locking groove 25 of the shift rod 16 and therefore in their Locking positions are (Fig. 4), displaceable in a release position in which the radial fixation of the locking elements 19 is released and the locking elements from the locking groove 25 of the shift rod 16 out in the control sleeve 21 are displaced (Fig. 2).
  • the gun 1 may first be in the firing position shown in Fig. 1, in which the shutter wedge 7 is closed.
  • the control element 10 has the control sleeve 21 of the control unit 1 1 against the pressure of the second spring 24 to the mouth of the gun barrel 3 moved into its release position (Fig. 2), so that the fixation of the shift rod 16 is repealed and the maximum extended piston rod 8 is in its initial position.
  • the shift rod 16 is therefore displaced in this position of the piston rod 8 against the pressure of the first spring 15 in the direction of the mouth of the gun barrel 3.
  • the bottom piece 4 of the gun barrel 3 is moved back to the cradle tube 2 by a pipe recuperator (not shown) (FIG. 5).
  • the maximum extended piston rod 8 hits the locked and disengaged in its initial position shift rod 16, so that the piston rod 8 is moved to the opening lever 9 back to its operating position, before the control 10 causes a displacement of the control sleeve 21 in the release position.
  • the shutter wedge 7 is moved by the pivoting opening lever 9 in its open position and ejected the cartridge case of the fired cartridge.
  • control element 10 reaches the control sleeve 21 and displaces it against the pressure of the second spring 24 in the release position (FIG. 6), so that the spherical locking elements 19 are displaced radially outward and the fixation of the shift rod 16 is canceled.
  • the shutter wedge 7 falls back slightly and is now from Shuttering arranged ejectors (not shown) held in its loading position.
  • the gun 1 can now be loaded.
  • the ejectors, not shown, are pivoted when inserting the gun 1 and release the shutter wedge 7 so that it is moved to its closed position.
