Definitions

  • the invention relates to a striking device with integrated safety device for firearms of the type specified in the preamble of claim 1.
  • a striking device is known to the person skilled in the art.
  • This mechanism which is housed in the base of the rifle, usually has a so-called striking piece, to which a correspondingly strong compression spring is assigned.
  • the striking piece When the rifle is cocked, the striking piece is directed towards the rifle butt, i.e. to the rear, pivoted until a release lever engages in a corresponding catch on the underside of the striking piece and thereby locks it in the clamping position.
  • the aforementioned compression spring is tensioned.
  • the shooter actuates the trigger of the rifle, which adjusts the trigger lever via a so-called rocker arm and thus releases the striking piece so that it is pivoted against the assigned firing pin under the force of the prestressed compression spring.
  • the firing pin in turn acts on the ignition element of the cartridge, which triggers the shot.
  • the invention has for its object to design a striker of the type mentioned so that the above disadvantages are avoided, i.e. It is ensured that the unwanted "going off" of shots is reliably excluded, regardless of the direction of the unintended impact forces acting on the weapon. It must also be ensured that the weapon can also be cocked and locked when the rocker arm is locked by a known, manually operated safety device.
  • This safety device is e.g. formed as a slider arranged on the top of the frame, which can be transferred manually from a "safe" position to a "release” position.
  • the impact piece is guided in corresponding guides of the frame and connected to the release lever, which on the one hand is pivotable and on the other hand has such a shape that on the one hand its rear end and the rocker arm engage in a form-fitting manner in the clamping position and on the other hand the front end of the release lever is in this position can be supported on a stop of the frame.
  • the release lever itself is additionally locked in an advantageous manner.
  • the striking piece is released in such a way that the usually provided "outer” slide lock of the rocker arm is to be canceled so that it can be moved by actuating the trigger of the weapon so that the positive connection between the rear end of the trigger lever and the rocker arm will be annulled. It is advantageously pivoted simultaneously by the rocker arm movement of the release lever so that its front end slides off at the locking stop and changes into a "release” position, whereupon the striker can be displaced into its relaxed position against the firing pin under the force of the prestressed compression spring.
  • the rocker arm instead of the forced pivoting movement of the release lever by means of the rocker arm, it can also be provided that the rocker arm only releases the rear end of the release lever and then, under the action of the prestressed compression spring, the front end of the release lever on the locking stop slides in such a way that the release lever in turn performs a pivoting movement and thus goes into the "release" position.
  • the trigger lever can e.g. be arranged on the underside of the striker designed as a slide, in which case corresponding recesses must be provided in the frame.
  • the training according to claim 2 is provided.
  • the rocker arm can be fitted with a correspondingly shaped cam, e.g. engage the rear end of the release lever.
  • the positive connection between the release lever and the rocker arm is preferably realized in accordance with claim 3.
  • a particularly advantageous arrangement of the off release lever is specified in claim 4, which leads to a particularly compact and robust design.
  • the front end of the release lever protrudes more or less over the top of the striker from the groove, so that it can be properly supported in the clamping position on the stop formed in the frame.
  • the release lever is then pivoted such that its front end is completely in the longitudinal groove, so that the striker can slide freely against the firing pin in the corresponding guide of the frame.
  • the release lever can be provided with a corresponding torsion spring in the region of its pivot axis.
  • the embodiment according to claim 5 is preferred.
  • the locking stop provided in the frame has a surface formed in such a way that, on the one hand, the release lever can be reliably supported on it with its front end in the tensioned position, and the front end of the release lever for transferring it into the release position of the release lever but in turn can slide smoothly at this stop with a corresponding tilting movement of the lever.
  • a training according to claim 6 proves to be particularly advantageous for this.
  • Figure 1 shows the striking device 1, which is arranged within the frame 10, in the clamping position A in the secured state.
  • the frame 10 is housed inside the basket, for example a rifle, which is not shown here.
  • the striking piece 2, which is designed as a parallel-flat slide, is moved by a tilting movement of the gun barrel, not shown, when cocked, in accordance with the arrow H 1, into the rear position A shown, it being guided accordingly in the frame 10.
  • the helical spring 3 assigned to the striking piece 2 is tensioned at the same time.
  • the longitudinal groove 15 is incorporated, in which the release lever 4 is housed.
  • the release lever 4 is designed as a slightly curved or slightly angled rod and can be pivoted about an axis 14 provided in the center thereof in the form of a pin.
  • the pin 14 is connected to the striker 2.
  • the length and the bend or curvature of the release lever 4 are selected such that in its "effective" position shown in FIG. 1, which is designated C, its rear end engages in a form-fitting manner in the groove 12 of the rocker arm 6 and engages with it its front end is supported on the stop 8, which is designed here as a roller rotatably fixed in the frame 1.
  • the front end of the release lever is pressed out of the groove 15 over the upper side of the striker 2 by the force of the compression spring 5 arranged in the striker 2.
  • the roller 8 is adjacent to the top of the striking piece 2 or at a short distance therefrom.
  • the rocker arm 6, which can be actuated via the trigger 7, is locked in the position shown by means of the “outer” securing means 9, which is designed here as a slide, and in the effective position Gi shown in the shown position by means of the cam 13 on the rocker arm 6 is present.
  • the slider 9 - as shown in FIG. 2 - is moved forward so that it assumes the position G 2 shown, in which the cam 13 is no longer supported on the upper side of the rocker arm 6.
  • the rocker arm is raised in accordance with the arrow T.
  • the rear end of the release lever 4 is forcibly lifted so that it slides out of the groove 12 of the rocker arm 6 and assumes the position D.
  • the front end of the release lever 4 is lowered into the groove 15 by a corresponding rotational movement of the roller 8 by this pivoting movement, which in turn releases the locking of the striking piece 2.
  • This can then be moved with relaxation of the coil spring 3 according to the arrow H 2 into the relaxation position B, ie forward against the firing pin, not shown, whereby the shot is triggered.
  • the trigger 7 is moved back in a known manner by spring elements, not shown, back to the starting position according to FIG. 1 and, accordingly, the rocker arm 6 is also brought back into the position shown there.
  • the weapon can be cocked and locked again by tilting the at least one barrel, ie the state shown in FIG. 1 again getting produced.
  • the trigger lever 4 is completely blocked by the rocker arm 6. This reliably prevents any unsolicited bumps from triggering shots. If the slide 9 is moved to the front ineffective position G 2 , the rocker arm 6 is released and the weapon is again ready to fire.
