Definitions

  • the invention relates to a handgun with a barrel having at least one transverse bore and a removable silencer which has an expansion space into which the transverse bore opens, with one in the Path of the combustion gases from the inside of the barrel into the expansion space, optionally operable closing device.
  • Such a weapon is essentially known from EP-A 0 071 799.
  • the silencer can be removed, in particular unscrewed, at least for cleaning purposes.
  • a locking device which can optionally be operated by the shooter, it has previously been accepted that if the weapon is fired with the muffler removed, there is a considerable risk of injury to the shooter in that the combustion gases emerge from the transverse bore and, for example, the hand of the Shooters can hit.
  • Such a danger also exists if the muffler is removed from the handgun described at the outset and, for whatever reason, the weapon then has to be fired if the shooter does not make sure that the locking device is closed in this case.
  • the invention has for its object to design a weapon of the type described in such a way that the described hazards to the shooter are avoided.
  • This object is achieved according to the invention in that the arrangement is such that an opening or keeping open the closing device is prevented in the absence of a silencer.
  • the advantage of the invention is that when the closing device is removed when the silencer is removed has been in its closed position, the closure device cannot be opened after removal, and that even if the silencer is removed when the closure device is open (if this is not prevented by the embodiments of the invention described below), the closure device remains open when the Silencer closes.
  • a locking device which senses the presence of the muffler and which prevents the closing device from opening when the muffler is missing.
  • the shooter can try to operate a handle provided for opening the closing device, but either the drive connection between the operating device and the closing device is canceled, i.e. decoupled, by the blocking device, or it is possible for the closing device or the actuating element of the closing device to move blocked.
  • the closing device cannot be opened if the silencer is missing.
  • the described embodiment can be developed in the manner in which it is provided according to an embodiment of the invention that the locking device is designed in this way is that when the silencer is removed, the closure device closes when the closure device is open.
  • an element to be actuated to open the closing device is arranged on the silencer, and that a spring holding the closing device in the closed position is provided in the absence of the silencer.
  • the closing device cannot be opened when the silencer is missing because the element to be actuated for the opening process is located on the removed silencer and is therefore not in drive connection with the closing device.
  • the closing device is kept closed by the spring as long as the muffler is removed or after said attachment the element has not yet been actuated to open the closing device. Even if it is possible to remove the silencer when the closing device is open, the closing device is immediately brought into the closed position by the spring mentioned.
  • the locking device is designed such that it blocks the position of the muffler when the closing device is open.
  • an actuating device for the locking device is mounted in a housing part of the weapon, depending on its actuating position, the locking device is opened or closed, and a bolt is provided which is held in a first position by the silencer in the operating position , in which he releases the actuation of the actuating device, and which, in the absence of the silencer, is in a second position in which it blocks the actuating device.
  • This embodiment can be implemented in a structurally simple and reliable manner.
  • the bolt interacts with a stop of the muffler in the operating position in such a way that a ' rotational movement of the muffler required to remove the muffler is prevented, and that a device for disengaging the bolt from the stop is provided .
  • the described rotary movement may be necessary in particular when unscrewing the muffler, but may also be necessary if the muffler is connected to the weapon by means of a bayonet catch.
  • the bolt is also a security against unintentional or unnoticed loosening or loosening of the muffler, so that this bolt therefore preferably does not automatically come into its unlocked position when the closing device is closed, but rather Device for disengaging the bolt is preferably designed so that it must be operated by the shooter specifically for the purpose of releasing the muffler.
  • the abovementioned stop on the muffler can preferably be part of a toothing of the muffler, and this toothing can, according to one embodiment of the invention, have sawtooth-shaped teeth, such that, when the muffler is attached to rotate, the bolt is counteracted by the oblique flanks of the teeth against the force of one Spring, with which it is held in contact with the toothing, is moved back, but, when the muffler is rotated in the opposite direction of rotation, bears against the locking flanks of the teeth lying essentially in axial planes with respect to the axis of the muffler.
  • the muffler can therefore only be released if the bolt is disengaged from the locking flanks by the device described above.
  • the actuating device has a shaft pivotably mounted in the housing part, with which a control disk is connected in a rotationally fixed manner, and the control disk has a recess into which a projection of the latch engages when the latch is in its second position (when Absence of the muffler or if the muffler is not completely in its operational position) and the actuating device is set such that the closing device is closed. With this out the closing device must be closed before loosening the silencer.
  • the advantage of this embodiment lies in the fact that a simple actuation possibility is created for the closing device, which can be used in a simple manner for unlocking the rotary movement of the silencer without constructive difficulties.
  • said control disk has a control cam which, when the control shaft is rotated starting from the position in which the closing device is closed, causes the closing device to open in a first direction of rotation.
  • control disc has a control cam which, when the shaft is rotated starting from the position in which the closing device is closed, engages on the bolt and the bolt from in the opposite direction of rotation as required for opening the closing device the stop of the muffler.
  • the silencer can be released in this position.
  • said control cam is designed so that when the shooter releases the actuating device, the control disc is moved back by the force of the spring that acts on the bolt into the position in which the bolt with the silencer removed into said recess in the control disc penetrates and prevents rotation of the control disk in the sense of opening the closing device.
  • a locking pin is slidably guided on the bolt, the end of which can be brought into engagement with recesses of the shaft which define locking positions of the shaft.
  • the locking pin can be displaced essentially in the same direction in which the bolt moves when the silencer is locked and released.
  • the locking pin could be driven by its own spring.
  • the spring that moves the bolt against the projection of the muffler is supported with its two ends on the one hand on the bolt and on the other hand on the locking bolt.
  • the closing device has a bolt which can be moved in a bore, the bore expanding in a funnel shape at one end and the bolt at the same end having a valve disk adapted to the funnel-shaped expansion has, it is provided that the bolt is displaceably guided that a spring engaging him in the closed position acts on the bolt, and that the actuating device is in drive connection with the bolt.
  • the bolt is not displaceable, but guided in a screwed manner and can therefore only be moved by a rotational movement about its longitudinal axis in the open position and closed position.
  • the drive device is in drive connection with the bolt via a two-armed lever. This makes it possible to drive the bolt, which will generally extend essentially transversely to the longitudinal direction of the tube, in a particularly space-saving manner.
  • the submachine gun shown in Fig. 1 comprises a housing 1 with a hand guard 10 covering the barrel, a sight 2 and a loading device 3.
  • the weapon further comprises a pistol grip 4 with a trigger box 5 and a trigger 6, as well as a shoulder rest 7, a rod magazine 8 and a muzzle muffler 9.
  • a weapon with the appearance of the weapon shown in FIG. 1 and with the parts just mentioned is known, with the exception of the switch lever 113, from the publication mentioned at the beginning.
  • a barrel 11 has a cartridge chamber 12 at its rear end, which is indicated by a not shown Closure part is closed, similar to that described in the publication mentioned.
  • Cross bores 14 penetrating the barrel wall are machined into the barrel at a short distance in front of the cartridge chamber 12 and open into an annular channel 16 provided on the outside of the barrel 11.
  • a threaded bushing 22 is screwed into a locking piece 20 which is fixed relative to the cartridge chamber 12, in such a way that its longitudinal axis is directed radially to the barrel 11.
  • the threaded bushing 22 has an external thread 23 with a length of approximately 2/3 of the thickness of the locking piece 20. At its end region facing the barrel, the threaded bushing 22 has a smooth cylindrical outer surface 224 which fits exactly into a cylindrical bore 225 in the locking piece 20. With its inner cylindrical end portion 226, the threaded bushing 22 engages in a precisely fitting cylindrical bore 227 which cuts the barrel 11 and whose diameter is slightly smaller than the diameter of the bore 225. The inner end face 228 of the threaded bushing 22 lies against the bore 225 delimiting end face 229 of the barrel 11. The end face 228 is annular.
  • the outer diameter of the threaded bushing 22 in the example is approximately as large as the outer diameter of the barrel 11, it is understood that the end face 228 cannot be in contact with the entire face of the end face 229 of the barrel 11.
  • the barrel 11 is precisely defined by the threaded bushing 22 and firmly held in the locking piece 22.
  • the threaded bushing 22 has wrench flats 230 for an open-ended wrench and can therefore be easily unscrewed. This allows the barrel to be changed easily because it is arranged in the locking piece 20 with a sliding seat.
  • the threaded bushing 22 has a bore which is formed approximately in the middle and upper part in the illustration in FIG. 2 as a smooth bore 26 and widens in its part closest to the barrel 11 to a funnel-shaped space 28.
  • the funnel-shaped surface bears the reference number 29.
  • Down the smooth bore 26 continues through a smooth bore 30 with a smaller diameter.
  • a bolt 32 is arranged in the bore 26, 30. It has a valve disk 34, the diameter of which is larger than the diameter of the bore 26 and which, in the position shown, bears against the funnel-shaped surface 29. Following the valve plate 34, the bolt 32 is tapered in a section 36, so that it has a smaller diameter than the bore 26.
  • the bolt 32 then widens again to the diameter of the bore 26 in a section 38, this section 38 is used for guidance as well as for sealing. Following the section 38, the bolt has a section 40 whose diameter is adapted to the diameter of the bore 30. The bolt 40 protrudes outward beyond the threaded bushing 22.
  • a tubular sleeve 44 is closed by means of a cross pin 42 be strengthens, the inner diameter of which is greater than the outer diameter of the section 40, and in the space formed hereby is arranged a compression spring 46 designed as a helical spring, which is supported on the one hand on a support surface 48 of the sleeve 44 and on the other hand on a surface 50 of the threaded sleeve 22 and thereby endeavors to keep the valve plate 34 constantly in contact with the surface 29.
  • the bore 26 is connected via five further bores 52 arranged in a star shape to an annular channel 54 provided on the outside of the threaded bushing 22, into which a bore 56 which penetrates the locking piece 20 and which connects to an expansion space 58 opens.
  • the expansion space 58 is delimited by the outer surface of the barrel 11 and a tubular part 62 with an end wall 64 which is penetrated by a channel 66 (or more channels) which opens into an annular channel 67 which is in communication with the bore 56 .
  • the tubular part 62 is permanently connected to the muffler 9.
  • the entire muffler arrangement comprising the muffler and the expansion chamber is screwed to the tube 11 in the vicinity of the cartridge chamber 12 by means of a thread 68 and is therefore detachably connected.
  • the thread 68 is a common right-hand thread.
  • a shaft 70 which is rotatably connected to the lever 13 (FIGS. 1 and 7) is pivotally mounted.
  • a control disk 72 is connected to the shaft 70 in a rotationally fixed manner, the plane of which runs parallel to the plane of the drawing in FIG. 2.
  • a latch 74 has a latch finger 76 pointing forward, to the left in FIG. 2, an angle 78 protruding downward from the housing 1, which is supported on a lower end face 80 and thus forms a guide for the latch 74, and one rear portion 82, which is in Fig.
  • the rear section 82 of the latch 74 carries a stop 86 which projects at right angles to the plane of the drawing in FIG. 2 and projects into the plane of the control disk 72.
  • a locking pin 92 is slidably guided, the rear-facing end is tapered and forms a locking lug 94 which is supported on the outer surface of the shaft 70.
  • the shaft 70 has two wedge-shaped recesses 96 and 98 adapted to the shape of the locking lug 94, and in two of three pivoting positions which the shaft 70 can assume, the locking lug 94 is located in one of the recesses 96 and 98 and thereby holds the recesses Shaft 70 in this swivel position.
  • the shooter can change the pivot position of the shaft 70 by operating the lever 13 .
  • the locking lug 94 thus forms a locking mechanism with the recesses 96 and 98.
  • the locking pin 92 is pressed against the shaft 70 by a spring 100 designed as a helical compression spring, which is supported on the one hand on a support surface 102 of the locking pin and on the other hand on a bolt 104 penetrating the bore 90 and fastened in the bolt 74.
  • a spring 100 designed as a helical compression spring, which is supported on the one hand on a support surface 102 of the locking pin and on the other hand on a bolt 104 penetrating the bore 90 and fastened in the bolt 74.
  • the prerequisite for this is that the bolt 74 is limited in its forward movement by an abutment.
  • This abutment is formed in the illustration of FIGS. 2 and 3 in that the locking finger 76 of the locking bolt 74 is supported on a sawtooth-shaped toothing 110, which is provided in an area 112 of the tubular part 62, in which this changes to a larger diameter is.
  • the individual teeth 114 of the toothing 110 each have an inclined flank 116 and a steep flank 118 lying in a radial plane with respect to the barrel 11.
  • the locking finger 76 is elastically pressed against the toothing 110 by the spring 100 because the locking bolt 92 is supported on the shaft 70. If the case is first considered that the muffler is detached from the weapon and is to be screwed on, the oblique flanks 116 push the locking finger 76 back against the force of the spring 100 when the muffler is turned to the right as soon as it is with the locking finger 76 come into contact. However, as long as the locking finger 76 assumes its position shown in FIG.
  • the muffler cannot be unscrewed by a screwing movement in the opposite direction of rotation, because in this case the locking finger 76 comes into contact with the steep flanks 118 and does not disengage due to a rotary movement of the muffler these steep flanks 118 can be brought.
  • the latch 74 forms thus, together with the toothing 110, a locking mechanism which is effective when the silencer is unscrewed, and a locking mechanism which is effective when attempting to unscrew the silencer.
  • a two-armed lever 132 is pivotally mounted, the two arms 134 and 136 of which have approximately the same effective length.
  • Arm 134 which faces rearward, abuts the lower end of sleeve 44, and front arm 136 lies in the same plane as control disk 72, but is in the position shown in FIG. 2, in which valve plate 34 abuts the surface 29, a small distance from the control disk 72.
  • combustion gases cannot get into the expansion chamber 58 when a shot is fired through the bores 14.
  • the shot energy is therefore not reduced, and if suitable ammunition is used, the projectiles leave the weapon at supersonic speed.
  • the muffler 9 causes a in the vicinity of the weapon certain noise reduction.
  • the shooter can also pivot the control disk 72 in FIG. 2 by pivoting the lever 13 (FIGS. 1 and 7) downward, namely counterclockwise, because the stop 86 does not enter the edge recess 130 engages.
  • the control disk 72 its control surface 140 presses against the upper side of the front arm 136 of the two-armed lever 132 and pivots the lever 132 counterclockwise, as a result of which its rear arm 134 lifts the valve plate 34.
  • This position is shown in Fig. 3. In this position, when a shot is fired, part of the combustion gases developed by the propellant charge of the ammunition escapes through the bores 14 into the expansion space 58.
  • the pressure of the propellant gases within the barrel 11 is reduced to such an extent that the projectiles only carry the barrel Leave subsonic speed so that the supersonic bang of the projectiles is avoided. Since the existing muffler also dampens the muzzle bang, the noise of the weapon is very effectively reduced in this position of the valve.
  • the compression spring 46 acts on the lever 132 in the sense of a pivoting movement in the clockwise direction.
  • the force exerted by the front arm 136 on the control disk 72 which acts essentially in the vertical direction, only acts on a relatively short lever arm, namely essentially at a point 146 which is only slightly further forward than the axis of the shaft 70 , this force exerted by the arm 136 is not sufficient to pivot the control disk 72 clockwise by pushing the locking bolt 92 back.
  • the shooter can switch on the position of the closing device shown in FIG. 2 by actuating the lever 1 3 starting from the position shown in FIG. 3.
  • the shooter can also pivot the lever 13 upwards, thereby making it possible to remove the silencer from the weapon.
  • the arrangement is such that the stop 86 is only fully pushed out of the edge recess 130 when the muffler is almost completely screwed on, so that the escape of combustion gases between the rear end region of the land 64 and the front end of the channel 56 is not or at least not to such an extent that faults or hazards are generated.
  • This also contributes to the fact that an annular projection 160 of the muffler, as known per se from the publication mentioned, penetrates into an annular groove 162 of the closure part 20.
  • the arms 134 and 136 of the two-armed lever 132 which can also be referred to as a lip, are of the same length. In other embodiments of the invention, however, it is possible to make the arm length different. It is thus possible to make the front arm 136 much longer than in the exemplary embodiment and, with the shaft 70, the control disk 72 and the locking bar 74, engage it with a control cam arranged on the outer surface of the muffler, which cam is also relative to the muffler is rotatable, in particular on a ring rotatably mounted on the muffler.
  • This control curve only engages with the extended arm 136 when the muffler is sufficiently wide (ie, there is a danger from escaping propellant gases) prevented) is screwed into the weapon.
  • the two-armed lever can then be pivoted and the valve plate 34 can be lifted off the surface 29. dird unscrewed the silencer, this eliminates the support for the front arm of the two-armed lever, and the valve plate 34 resumes its closed position.
