Definitions

• the invention relates to a handgun with a breech which is movable in an end position set up for firing a cartridge, a firing pin which is movably mounted in the breech along a preferably linear movement path, and a striking device which can be triggered by a trigger device and is set up for this purpose Igniting a cartridge to strike the firing pin end facing away from it and thereby to bring the firing pin into its firing position, according to the preamble of claim 1.
• Positional terms used in the following, such as “above” or the like, are based on the horizontal position of use of the weapon when firing, the firing direction pointing "forward" (to the left in the drawing).
• Lock penetrated and by a firing pin spring is pushed backwards such that its rear end protrudes from the closure by a protrusion distance and its front end, the tip, is set back at least by the protrusion distance from the front end face of the closure.
• the valve strikes the rear end of the firing pin, it accelerates and, due to its inertia, moves forward against the force of the firing pin spring, where it emerges with its tip from the end face of the breech, the bump bottom, and can strike the primer of the cartridge sitting on the bump floor from the front.
• a striking piece can also be provided, which, like a tap, cannot be pivoted about a fixed axis, but instead is guided, for example, in a straight line of motion and is movable under the load of a striking spring.
• a tap is used.
• an interruption mechanism is provided in the trigger device, which only then creates the triggering connection between the trigger and the tap or only releases the tap in case of continuous fire when the shutter is fully closed.
• This interrupter mechanism is controlled by the position of the breech, so that in principle a shot can only be fired when the breech is completely closed.
• the object of the invention is to provide an additional device, which inevitably allows a shot to be fired only when the breech has inserted the cartridge sufficiently far into the chamber.
• the invention therefore provides a separate device, the purpose of which is to prevent the firing pin from reaching its firing position until the breech has reached its end position to the extent of safety. It is clear to the person skilled in the art that the end position is not a point along the movement path of the closure, but rather a
• This invention also ensures that, for. B. a certain opening of the closure can occur by bouncing the closure, but the firing pin is controlled immediately from its application area of the tap.
• the additional device according to the invention could consist, for example, of a rocker arm which is pivotably mounted in the closure, can be pressed by a spring with its one leg into locking engagement with the closure and with its other end on the front end face or a side surface of the closure above it survives.
• this protruding leg In the path of movement of this protruding leg is on the barrel or a stop surface is provided on the housing, against which this protruding limb runs when the closure is closed and thereby lifts the other limb of the rocker arm out of engagement with the firing pin.
• the arrangement of the stop surface is such that the firing pin is only released when the closure has reached the tolerance range of its end position.
• Teeing facility to be knocked out. According to the invention, it is therefore preferred to remove the firing pin from the range of motion when ignition is to be prevented
• the firing pin could be tilted so that its rear end is offset transversely to its direction of movement, as is known from certain safety devices.
• the firing pin is moved forward to such an extent that it is still reliably behind its firing position, but immersed so far in the breech that its rear end before contact with the tap or an impact piece by forming the breech, preferably the rear end surface of the fastener, is protected.
• This configuration is particularly preferred in the case of a weapon in which the cock lies entirely within the housing, so that there is no risk that a foreign body will get between the cock and firing pin and could still cause ignition.
• the firing pin could be brought into the security position described by the closing spring acting on the closure.
• a counter spring is provided which is supported between the breech and firing pin, but can only push it into its safety position.
• the spring force of the counter spring is higher than that of the firing pin spring used (claim 4).
• the counter spring engages with a stationary housing design, for example a housing projection or the like, and thereby breaks off its action on the firing pin, which is now moved back so far by the action of its firing pin spring can that the tap can then hit the firing pin freely.
• the stationary housing design could be produced, for example, as an indentation of a housing formed from sheet metal;
• this housing design is preferably designed as a separate component, which can accordingly be made from a highly wear-resistant material optimized for its purpose (claim 5).
• This separate component can be non-detachably fastened in the housing, for example by composite casting, but can also be detachably attached, so that if it should be worn or damaged, it can easily be replaced by a new component or fitted before final installation can.
• This component is preferably provided with an engagement formation which engages in a counter-formation on the barrel, so that the critical distance between the rear end of the barrel and thus the cartridge chamber and the surface or edge of the component which cancels the action of the counter spring can be effortlessly achieved with a very narrow tolerance range can be maintained.
• the said separate component is preferred as
• Cartridge ejector formed (claim 6), which must be formed from wear-resistant material anyway and on which, according to the invention, a surface or edge is formed: that serves to intercept the counter spring or the part assigned to it. It is thus possible to provide the above-mentioned, separate component made of optimal material without an additional component of the weapon being necessary. It is therefore possible to provide a weapon of the type mentioned at the outset in a highly economical manner with a new type of safety device that is completely independent of the trigger device, and thus also from the accumulation of tolerances and wear, which ultimately can hardly be avoided with a trigger device are.

• An ejection window 12 is formed in the housing 11 to the side of the closure 15 when it is in its front end position.
• the breech 15, which is also shown in Fig. 5, is penetrated lengthwise in the middle by a firing pin 3, which is loaded by a firing pin spring 1 to the rear in such a way that it seeks to assume a position in which the rear firing pin end 10 comes from rear end face of the closure 15 protrudes to the rear by a projection Y (FIG. 3).
• a cock 9 is pivotally mounted, which is only very schematically indicated in FIGS. 3 and 4.
• This cock 9 can knock from a ⁇ pannlage, in which its upper end is arranged at a distance behind the front end position of the closure (Fig. 3) in a knock-down position, which is shown in Fig. 4 and in which the cock 9 to the rear over the breech 15 protrudes rear firing pin end 10; this causes the firing pin 3 to be thrown forward, strikes the primer of the cartridge 14 and thereby fires it (FIG. 4).
• a weapon is known from the prior art.
• an extractor and securing device in the form of a leaf spring 16, the rear end of which has a projection which engages in front of an end collar 20 of the firing pin 3 and prevents it from moving forward.
• the knocking-off valve 9 hits an inclined surface on the leaf spring 16 and deflects it in such a way that its projection is moved out of engagement with the collar 20 and only then is the firing pin released immediately before the valve 9 strikes.
• This leaf spring 16 is described in the German patent application 197 02 374.6-15 by the applicant; the disclosure of this patent application is expressly incorporated into the present documents by reference.
• this leaf spring 16 is modified such that it does not completely fix the firing pin 3 in its rearmost position, but rather leaves it with a certain mobility (over the distance X + Y) in the longitudinal direction to the front.
• the striker 3 is still prevented by the leaf spring 16 from moving with its tip beyond the front end face of the closure 15, as long as the cock 9 has not pushed the leaf spring 16 out of engagement with the striker 3 by its knocking off.
• the front end of the leaf spring 16 is designed as an extractor.
• the closure On the longitudinal side opposite the leaf spring 16, the closure has a longitudinal groove 18 opening into its front end face, into which an ejector projection 17 engages, which is formed on a fixed engagement part 8 fastened in the housing 11, which is designed as a sheet steel component, the engages with its front end in a recess in the outside of the barrel 13 near the rear end.
• the longitudinal groove 18 runs back over the projection 17 until the bottom of the cartridge case against the
• Front edge 19 of the projection 17 hits and is thereby ejected, whereby it is ejected through the ejection window 12.
• the firing pin 3 seen from the front to the rear (from left to right in the drawing), has a thin tip, followed by a thicker but slender shaft that extends approximately to the middle of the length of the firing pin 3, followed by a thickened, cylindrical one Section 21 and finally the already mentioned final covenant
• the firing pin spring 1 is guided on the slim shaft and is supported with its rear end on the shoulder which forms the transition between the slim shaft and the thickened section 21.
• a stop piece 6 with its longitudinal through bore, a helical counter spring 5 and a sleeve 4 with its longitudinal through bore are pushed onto the firing pin 3 and pressed backwards with a slight compression of the counter spring 5; a securing ring 2 is then attached, which sits in an annular groove which is introduced into the area of the transition between the shaft and the thickened section 21 of the firing pin 3.
• This locking ring 2 forms a front stop for the sleeve 4 and holds the parts together as an assembly.
• the sleeve 4 and the stop piece 6 each have a lateral projection which is guided in the longitudinal groove 18; in addition, the stop piece 6 is held stationary in the closure 15 by means of a mounting pin 7.
• the sleeve 4, starting from the rear end surface, has a blind bore, just like the stop piece 6, in which the blind bore starts from the front end surface.
• the counter spring 5 penetrates into each of the blind bores and is supported on the respective end face of the bore.
• the sleeve 4 sits with its front end face on a shoulder in the longitudinal bore in the closure 15.
• the firing pin spring 1 is supported with its front end on another shoulder in the longitudinal bore mentioned, with its rear end on the shoulder of the firing pin.
• the counter spring 5 is stronger than the impact pin spring 1, so that the counter spring 5 always tries to press the sleeve 4 against the action of the firing pin spring 1 to the front. If the breech is removed from the weapon, for example, as shown in Fig. 5, then the sleeve 4 sits on the associated paragraph of the breech longitudinal bore and presses the locking ring 2 and thus the firing pin 3 forward, so that the rear firing pin end 10 is offset forward by the dimension X relative to the rear end of the closure 15. In this position of the firing pin 3, which is shown, for example, in FIG. 2, the tap 9 hits when knocking off on the rear surface of the breech 15 without being able to reach the rear firing pin end 10.

• the front edge 19 of this projection 17 forms the ejector edge; if the breech 15 is moved backwards with a cartridge 14 or an empty cartridge case, the edge of this cartridge 14 or cartridge case meets the ejection edge 19 on the side opposite the ejection window 12 and is ejected by the latter.
• the projection 17 On the rear side opposite the ejector edge 19, the projection 17 has a further functional edge which is designed to engage in the lateral projection of the sleeve 4 and then to prevent this and thus the sleeve 4 from moving further forwards.
• This functional edge of the engaging part 8 strikes the lateral projection of the sleeve 4 when the breech is still a distance X + Y from its front end position which it is to assume when firing.
• the front end of the engaging part 8 engages in a recess of the barrel 13, so that the rear func tional edge of the projection 17 always remains at a fixed distance from the barrel 13 and thus from the position which the bottom of the cartridge 14 assumes when shot.
• Fig. 1 the closure 15 is shown as it moves forward; he has just removed a cartridge 14 from the magazine (which is hidden by the breech 15), with the extractor caral (at the front end of the leaf spring 16) detects and introduces them into the cartridge chamber of barrel 13.
• the leaf spring 16 engages with the projection in its rear region the collar 20 of the firing pin 3.
• the sleeve 4 is in its front end position and takes the firing pin 3 so far forward over the locking ring 2 that its rear end 10 by the distance X is offset from the rear end of the closure 15. If the cock 9 should accidentally knock off, it would hit the rear end of the closure 15, but not touch the firing pin 3.
• the lateral projection of the sleeve 4, which is guided in the longitudinal groove 18, is removed from the rear functional edge of the projection 17 of the engaging part 8 by the distance Z which the closure must at least still travel without the cartridge 14 being allowed to be fired.
• the closure 15 has moved forward by the distance X + Y relative to the position shown in FIG. 2 and has reached its prescribed end position in which the cartridge 14 is fully seated in the cartridge chamber.
• the sleeve 4 was held during the last phase of movement of the functional edge of the projection 17 of the engaging part 8, so that it is now removed from the associated paragraph in the longitudinal bore that receives the firing pin 3.
• the firing pin spring 1 loads the locking ring 2 and thus the firing pin 3 to the rear, so that the locking ring 2 still bears against the front end face of the sleeve 4 and the rear firing pin end 10 projects beyond the distance Y beyond the rear end of the closure 15 to the rear.
• Positional terms used in the following, such as “above” or the like, are based on the horizontal position of use of the weapon when firing, the firing direction pointing "forward" (to the left in the drawing).
• an interruption mechanism is provided which only establishes the triggering connection between the trigger and the tap or in the event of continuous fire only releases the tap when the shutter is fully closed.
