Definitions

• the invention relates to a firing pin holder on a breech for a handgun, the breech being penetrated by a firing pin.
• the designations in the following description are based on the normal position of use of a handgun with a horizontal soul axis (barrel center axis), the direction of the shot pointing "forward".
• the firing pin center axis usually coincides with this soul axis.
• the firing pin In the case of small arms, the firing pin should be inspected occasionally in order to identify any compression or crack. These can form if the firing pin is not properly hardened due to a manufacturing inaccuracy, or if it has hit a too hard surface due to the penetration of a jammed grain of sand. Such errors occur extremely rarely, but cannot be completely excluded. Even if a weapon has fallen into the water or is very dirty, the firing pin should be removed in order to be able to clean it and its guide bore.
• the firing pin is generally only removed by the gunsmith or specialist personnel, provided that the removal does not result from the usual dismantling of the weapon. With modern rapid-fire guns, the soldier is even expressly prohibited from removing individual parts, such as the firing pin. The soldier may only disassemble his weapon to the extent that is absolutely necessary for normal cleaning and care.
• a firing pin holder which has a cross slide (DE-PS 741 616).
• this cross slide requires a guide, the manufacture of which is expensive.
• DE 196 05 851 AI a cross slide is also known, which serves as firing pin safety.
• the invention has for its object to find an improved firing pin holder.
• This firing pin holder should preferably be able to be detached and attached easily and without tools and if possible have no small parts that can be lost.
• the slide could, for example, consist of a spring pin which penetrates an elongated hole in the firing pin and is bent up on both sides thereof.
• the slide is sufficiently freely accessible so that it can be simply pressed against it with your finger. If the slide is released, it is still attached to the firing pin and therefore cannot be lost.
• the spring force can originate, for example, from the firing pin spring, which presses the firing pin back so that it does not constantly protrude from the front of the closure.
• the firing pin has a projection which is pressed by the action of the firing pin spring against the slide and thereby loads it to the rear (claim 2).
• the term "lead” is to be understood in the broadest sense. That would be about the front end of the above-mentioned elongated hole in the impact bolt ⁇ such a projection.
• Pressing in the firing pin can help to release the slide, so that the preload exerted by the firing pin spring is released.
• an ejector or ejector pin is provided which passes through the breech parallel to the firing pin. This ejector must be implemented when changing the cartridge ejection, so removed just like the firing pin and then reinstalled in the appropriate place.
• the slide can be translationally movable transversely to the longitudinal central axis, but is preferably designed and arranged as a rotary slide (claim 3). If, when the weapon is assembled, the rotary slide comes loose from its engagement in the breech due to a fault or if the breech is accidentally inserted with the rotary slide not properly installed in the weapon, then the slide does not protrude laterally beyond the breech, like a slide which can be moved in translation . Therefore, it cannot cause an inhibition of charging.
• the center of rotation of the rotary valve is chosen as centrally as possible in the closure, so that the rotary valve can be rotated around the firing pin (claim 4).
• the firing pin must be movable in its longitudinal direction when the rotary valve is stuck in order to be able to ignite a cartridge. So that the rotary valve does not hinder this longitudinal movement, it is provided according to a development of the invention (claim 5) that the firing pin with a length section with a reduced diameter penetrates a bore of the rotary valve which is dimensioned to this diameter. At the ends of the length section there is a step with an enlarged diameter which cannot pass through the bore.
• the material of the rotary valve is preferably adapted to the reduced cross-section of the longitudinal section by permanent deformation or by resilient deformation, which results in particularly simple assembly and reliable captivity.
• radial slots are formed, which start from the bore of the rotary valve.
• the rotary slide valve can have openings or axial projections which engage in projections on the closure.
• circumferential tabs are preferably formed on the rotary slide valve, which extend radially outward, lie within the closure cross-section in each rotary position of the slide valve, and on the securing position
• This spring washer is preferably symmetrical with respect to the vertical axis (claim 9). This is particularly Partial for a weapon with a selectable cartridge ejection direction, since the ejector is located there on one side or the other in the breech.
• the symmetry mentioned also has the advantage that incorrect assembly is not possible due to the incorrectly oriented spring washer. Because of the symmetry of the spring washer, it does not matter which of your surfaces it faces forwards or backwards.
• the spring washer has two short circumferential tabs standing down and one long circumferential tab standing centrally up.
• the long circumferential tab engages - from the front and under the spring tension of the spring washer - in a locking recess which is formed on the front of a projection of the closure carrier.
• the long circumferential tab only has to be pushed forward with your finger from the back in order to be lifted out of the latch at the front. An oblique load on the long circumferential tab with the user's finger then turns the spring washer so far that it is released from all projections.
• FIG. 1 is a side view of the breech of a rapid-fire rifle which is equipped with the firing pin holder according to the invention
• FIG. 2 shows a longitudinal section through the closure of FIG. 1,
• Fig. 3 is a view of the closure of Fig. 1 from behind from the direction of arrow A, with the firing pin holder locked
• Fig. 4 is a view as in Fig. 3, but with the firing pin holder unlocked.
• a closure which is formed from a closure carrier 1 and a closure head 3.
• Breech holder 1 and breech head 3 have a central longitudinal bore in which a firing pin 5 is seated, which is pressed backwards by a firing pin spring 7.
• An ejector 9 is provided parallel to the firing pin 5 and passes through the closure 1, 3 on the left side next to the firing pin 5. At the extreme edge of the closure head 3, an extractor claw 11 is attached at the front right.
• the firing pin 5 holds a control pin (not shown in more detail) in its position. If the firing pin 5 is removed, the control pin can be removed and the locking head 3 can be removed from the locking carrier 1.
• the closure head 3 can be installed in two different positions, either with the extractor claw 11 on the left and the ejector 9 on the right (cartridge ejection to the left) or, as shown, with the extractor claw 11 on the right and the ejector 9 on the left (cartridge ejection to the left) right) .
• the control pin is then reinserted and secured with the firing pin 5.
• the firing pin 5 has a length section 17 at its rear end, which is delimited at the front by a shoulder 19 and at the back by a thickening 21, both of which have a larger diameter than the length section 17.
• a generally approximately Y-shaped, flat locking washer 23 made of spring plate has a bore at the intersection of its legs.
• the legs are formed by two short 27 and one long 29 peripheral tab.
• the middle never the long circumferential tab 29 lies on the vertical axis of the weapon and forms an axis of symmetry for the locking washer 23.
• Three short slots 25 extend radially from the bore of the locking washer 23, between which material tongues remain which can spring out of the plane of the locking washer 23.
• the Y-shaped locking washer 23 Concentric to the bore, the Y-shaped locking washer 23 has a section with a circular arc-shaped peripheral edge 31 in the region of the junction of its three legs.
• the locking washer 23 is pressed onto the thickening 21 with its bore from behind.
• the material tongues between the slots 25 then yield resiliently and allow the thickening 21 to pass through the bore (which is too small).
• the material tongues spring back, so that the locking washer 23 with its bore encloses the longitudinal section 17 with little play, that is to say it is captively attached to the firing pin 5, but does not hinder its limited axial movement.
• the locking washer 23 can assume a locking position or a release position.
• the securing position is shown in Fig. 3.
• the firing pin 5 is fastened in it in the closure carrier 1.
• the release position is shown in Fig. 4. In it, the locking washer 23 is rotated in its plane by an angle of 45 ° with respect to the locking position and can be removed together with the firing pin 5.
• each of the two lower projections 13 has a circumferential groove. Both circumferential grooves are open radially inwards and have approximately the same radius around the firing pin 5. In the circumferential direction, the distance between the two lower projections 13 is dimensioned so that a short circumferential tab 27 remains within this distance and can be lifted out to the rear. In the secured position, however, the radially outermost ends of the two short peripheral tabs 27 engage in the peripheral grooves of the lower projections 13.
• An upper projection 15 assigned to the long circumferential tab 29 has a forward-facing surface in which a recess is made to the rear, which can receive the end of the long circumferential tab 29.
• the bottom of the depression lies approximately in the plane of the rear side edges of the circumferential grooves in the lower projections 13.
• the circumferential dimension of the upper projection 15 is selected so that the long circumferential tab 29 in the release position of the locking plate 23 has emerged laterally in front of the upper projection 15 and the locking washer 23 with the firing pin 5 can be removed from the closure carrier 1.
• the long peripheral tab 29 (possibly with spring preload) is seated in the recess of the upper projection 15.
• the side surfaces of this recess positively prevent the locking washer 23 from being turned unintentionally.
• the lock washer 23 is not only captive because it is permanently attached to the firing pin 5.
• the component created from disk 23 and firing pin 5 is also so bulky that (in contrast to the firing pin 5 alone) cannot easily be lost.
• the bottom of this latching recess can lie so far in front of the plane defined by the circumferential grooves in the lower projections 13 that the long circumferential tab 29 sits in its latching recess with a strong prestress.
