Definitions

  • the invention concerns a blocking device for a pistol.
  • U.S. Pat. No. 3,553,877 A demonstrates a weapon, in which a type of locking tab extends into the motion path of the trigger slide, which tab can be brought by means of a key from this position into a position in which movement of the trigger slide is not adversely affected.
  • This mechanism is as bulky as the entire trigger mechanism, which plays no role in weapons with a big shaft, but prevents application in pistols and revolvers.
  • U.S. Pat. No. 4,136,475 A demonstrates a similar device adapted for revolvers, in which the lock and locking mechanism are accommodated in the grip of the revolver. Since the revolver grip with its entire volume is available for this purpose, it is possible with this device to accommodate such a blocking device, but accommodating it in the grip of a pistol in which the magazine is situated is ruled out. To this we must add that the slide is situated directly above the grip in pistols and no space is therefore available there for a blocking device.
  • a miniaturized cylindrical lock is arranged in the grip of the weapon behind the magazine and whose closing cylinder can be rotated with a key, and, by a rotary movement by means of a transmission mechanism that can include rods, levers, threading, etc., a blocking element can be brought from a position in which it is situated outside the movement path of part of the trigger mechanism of the weapon into a position in which it extends into the movement path of this part during the trigger movement.
  • Cylindrical locks are known per se and are excellently suited for the present purpose because they are quite stable mechanically even in miniaturized form and permit the use of keys, also in miniaturized form, which have a large number of key-lock combinations, so that it is possible to use several thousand different keys even in such small locks and thus reduce the hazard of inadvertent fitting of a key.
  • the rotational movement of the closing cylinder can be converted into a translatory movement by means of a torsion bar and a type of reversed nut-spindle design, through which translatory movement ultimately a protrusion, a tab, a slide or the like is pushed far enough so that it extends into the path of the firing pin tab and prevents release of the shot.
  • the device in one embodiment, it is also proposed to incorporate the device so that it can only be disassembled free of disturbance with cooperation of the corresponding key, in order to prevent a stolen weapon from being broken down (removal of the slide) and the safety mechanism then disassembled.
  • an indicator pin or indicator plate should extend through a slit in the housing of the weapon, preferably in the rear region of the grip, and indicate both optically and by touch whether the weapon is blocked or released.
  • FIG. 1 shows a weapon equipped with a blocking device according to the invention without the slit, in cross section along the center plane of the weapon,
  • FIGS. 2 and 3 show details II and III of FIG. 1,
  • FIG. 4 shows a part of the known trigger mechanism of a pistol, provided with a blocking device according to the invention in the open position
  • FIG. 5 shows the depiction of FIG. 4 in the blocked position
  • FIG. 6 shows the mechanism of FIGS. 4 and 5 in a perspective view
  • FIG. 7 shows a hammer pistol equipped according to the invention.
  • a blocking device according to the invention is apparent from FIG. 1, showing that the invention makes it possible to incorporate a reliable blocking device even in pistols, with very limited space requirements.
  • a blocking device 14 according to the invention is accommodated in the housing 1 of a pistol with a grip 2 , which has a shaft 26 for a magazine, in the rear region of grip 2 .
  • the blocking device 14 consists essentially of a cylindrical lock 3 arranged in the lower region of grip 2 , which lock can be operated with a corresponding key 7 , i.e., the closing cylinder can only be rotated when a key 7 is inserted.
  • the rotational movement of the closing cylinder is transmitted to a rotating rod 6 and a converter 4 arranged in the upper region of grip 2 , which is further described below with reference to FIG. 2, and converted to a translatory movement that causes a blocking plate 9 (FIGS. 4 and 5) to be situated either, as shown in FIG. 4, in a lower position that releases the weapon, or into a blocking position pushed upward.
  • FIG. 3 shows the region of the lock 3 of the blocking device 14 according to the invention in an axial section with the key 7 inserted.
  • the closing cylinder can be rotated around its rotational axis and thereby entrains the lower end of the rotating rod 6 that runs normal to the axis of rotation in a longitudinal slit.
  • a moving stop is provided in the depicted example, which permits rotation of the key by 360°, so that it poses no problem for the user to find the correct rotational position for removal of the key.
  • An indicator 8 which in the blocked position of blocking device 14 emerges outward through a slit-like recess in the rear region of grip 2 and therefore indicates to the user both optically and by touch during handling of the weapon that the weapon is in the blocked state and that no shot can be fired, is connected to the movable stop.
  • FIG. 2 shows the upper region of the rotating rod 6 , the converter 4 , which is called this because the rotational movement of the rotating rod 6 is converted in converter 4 to a translatory movement of the blocking plate 9 .
  • This conversion occurs through a threaded piece 16 positioned rotationally fixed, but axially movable on the lance-like, flattened tip 17 of rotating rod 6 and cooperates with its threaded section 18 arranged on the outer surface with a not shown protrusion of the hole 19 of a connector mount 22 , in which the threaded piece 16 sits.
  • the connector mount 22 carries a driver pin 28 that moves an operating device 29 for the blocking plate 9 .
  • the converter 4 operates in similar fashion to a spindle-nut device, in which the rotational movement of the spindle is also converted to a translatory movement of the nut.
  • the rotary movement of the threaded piece 16 thus causes translatory movement of the operating device 29 , so that its direction of motion need not fully coincide with the direction of rotating rod 6 or with the direction of the rotational axis of threaded piece 16 and significant deviations are quite possible.
  • the operating device 29 carries the actual blocking plate 9 on its side facing away from converter 4 , which plate is forced into a blocking position by a spring (not shown) and brought into the release position against the force of this spring by the operating device 29 . Because of this, even with extensive destruction of the blocking mechanism, this is held in the blocking position and the weapon remains inoperable.
  • a stepped holding surface (FIGS. 4 and 5) formed on it prevents a trigger tab 10 of the trigger mechanism, designated 13 in its entirety, from moving downward during operation of the trigger 27 (FIG. 7).
  • This downward movement of the trigger tab 10 and the clamping edge 12 connected to it (FIG. 1) permits the firing pin tab 11 , extending downward from the slit (not shown), to be released and accelerated toward the cartridge (to the right in FIG. 1) under the influence of the firing pin spring (not shown), thus releasing the shot.
  • the trigger device 13 depicted in FIGS. 1 to 6 corresponds to the trigger devices disclosed in U.S. Pat. No. 4,539,889 A, U.S. Pat. No. 4,825,744 A and U.S. Pat. No. 4,893,546 A, the disclosure of these documents being included in the disclosure of the present application by reference.
  • the depicted blocking device 14 is also characterized by the fact that, even when the weapon is broken down, i.e., with the slide removed, as shown in FIG. 1, it is not possible to disassemble it, regardless of its momentary blocking or open position, as long as the matching key is not available.
  • the upper region of blocking device 17 together with the threaded piece 16 , is held by a retaining pin 20 in the direction of rotating rod 6 , specifically by a recess 21 in the connector mount 22 .
  • the recess 21 has an essentially circular shape and opens downward (toward rotating rod 6 ) with a radially running slit 25 . Only when the retaining pin 20 lies in the direction of slit 25 is it possible to separate the rotating rod 6 from the threaded piece 16 .
  • the direction of slit 25 is chosen according to the invention so that it does not coincide with either the open position or the blocked position, but with an intermediate position. This intermediate position can only be reached with the inserted key 7 , since the key can only be withdrawn in the open position or blocked position.
  • a blocking tab 9 ′ can extend into a notch, recess 24 , etc. of a part that is rotated with hammer 23 , in order to block the weapon.
  • a type of kinematic reversal is also possible, in which a protrusion on hammer 23 cooperates with a corresponding surface of the blocking tab 9 ′.
  • the blocking tab 9 ′ can be forced under the influence of a spring into the movement path of recess 24 , when this is desired.
  • Both metal, for example, steel, especially for rotating rod 6 , and plastic can be used for the blocking device material according to the invention and, in particular, the connector mount 22 , the threaded piece 16 and other parts can consist of plastic and the lock 3 and its cylinder, as well as key, can be purchased in a shop in the form of a precision part.
