Abstract

An assembly for mounting a firing pin to a bolt assembly of a firearm is provided and includes a bolt assembly adapted for mounting to the firearm, a firing pin mounted to the bolt assembly for reciprocating movement relative to the bolt assembly, and a retaining member releasably engaging a portion of the bolt assembly and slidably engaging a rearward portion of the firing pin. The retaining member is shiftable between an engaged position in which the retaining member is secured to the bolt assembly and a release position in which the retaining member and the firing pin are removable from the bolt assembly. The retaining member is biased against the portion of the bolt assembly when the retaining member is in the engaged position.

Description

The invention relates to a firing pin holder according to the preamble of claim 1. Such a firing pin holder is known from GB 803 034 A.

For the sake of simplicity, the location designations in the following description throughout from the normal Use position of a handgun with a horizontal soul axis (Center line of the barrel), the Shot direction "forward" points. The firing pin center axis usually falls with this soul axis together.

For small arms, the firing pin should occasionally to be inspected for any compression or any To be able to determine the crack. These can then form if the firing pin is due to a manufacturing inaccuracy is not properly hardened, or if it is about by penetration of a jammed grain of sand a hard surface has been hit. Such mistakes occur extremely rarely, but cannot completely be excluded.

Even if a weapon falls into the water or very strongly the firing pin should be removed, to be able to clean it itself and its pilot hole.

The firing pin is generally only used by the gunsmith or expanded by specialist personnel, insofar as the Expansion not in the course of the usual dismantling of the Weapon results. It is with modern rapid-fire guns the soldier even expressly forbidden individual parts, like the firing pin. The soldier is allowed to disassemble his weapon only to the extent that it is normal Cleaning and care is essential.

Furthermore, a firing pin holder is known, the one Cross slide has (DE-PS 741 616). This cross slide however requires a guide, the manufacture of which is expensive is. From DE 196 05 851 A1 is also a cross slide known, which serves as firing pin safety.

However, the applicant has a self-loading handgun invented and at the same time with the present invention to Patent pending (German patent application No. 199 03 327.7 "Locking device for a handgun", file number the applicant H0473-084-DEPOOSk), in which the locking head can be installed in two different positions is to selectively eject the cartridge to the right or left to be done. The content of that patent application is expressly stated by the above reference in including the available documents. At a preferred embodiment of this handgun is required when moving the breech head Remove firing pin. With a conventional one A firing pin holder would require a tool for this. Moreover small parts would come free (such as a spring washer), the easily lost or damaged if installed incorrectly could become.

Based on this problem, the invention is the Task based on an improved firing pin holder to find. This firing pin holder should preferably can be easily detached and attached without tools can and if possible have no small parts that can be lost.

The above object is achieved by the subject of claim 1 solved, that in that at the beginning called a firing pin holder a slide that extends across the firing pin, longitudinally attached to this and also in resilient engagement with the closure can be brought.

FR 2 609 538 (MANURHIN) relates to a facility with convertible firing pin, so that for central and rimfire cartridges the same firing pin can be used is. The firing pin is held by a cross pin, the longitudinally displaceable compared to the firing pin but is firmly and unsprung in the weapon.

DE 334 448 C (WALTHER) relates to a firing pin transverse, longitudinally movable holding pin, the in one piece with the extractor via a leaf spring section connected is. The retaining pin itself is stuck and unsprung in the breech of the weapon.

By overcoming the spring force that engages the slider holds, this can be solved and then together with the Firing bolts are removed; the latter because the Slider is also connected to the firing pin - however, so that the firing pin is its trigger can perform the necessary longitudinal movement of a shot.

The slide could, for example, from a spring pin consist of an elongated hole in the firing pin and is bent up on both sides of it.

To overcome the spring force without tools is the Slider attached freely accessible so that can simply be pressed against it with your finger. When the slide is released, it still hangs on the firing pin and therefore cannot be lost.

The spring force can, for example, from the firing pin spring that pushes the firing pin back, so that he doesn't constantly come out of the front of the breech protrudes. The firing pin has one Projection by the action of the firing pin spring is pressed against the slider while doing this burdened behind (claim 2). The term "lead" is to be understood here in the broadest sense. That would be about the front end of the slot mentioned above in the firing pin such a head start.

Press the firing pin to release the slide contribute to so that from the firing pin spring cancel the applied preload.

With some weapons, especially the above Self-loading weapon, in which the cartridge ejection is switched is an ejector or ejector pin provided the lock parallel to the firing pin interspersed. This ejector must be used when changing the cartridge ejection be implemented, just like the Firing pin removed and then on the appropriate one Point to be reinstalled.

The slide can translate transversely to the longitudinal central axis be, but is preferred as a rotary valve designed and arranged (claim 3). Should the Rotary slide valve through one with the weapon assembled Release errors from its engagement in the closure or should the clasp accidentally not work properly built-in rotary valve in the weapon, then the slide is not laterally above the closure beyond, like a translational slider. Therefore, it cannot cause an inhibition of charging.

The center of rotation of the rotary valve is from the same Reason chosen as centrally as possible in the closure, so that the Rotary valve is rotatable around the firing pin (claim 4).

Now the firing pin must be with the rotary valve stuck be movable in its longitudinal direction around a cartridge to be able to ignite. So that the rotary valve this longitudinal movement According to a further training, the Invention (claim 5) provided that the firing pin with a length section with a reduced diameter a bore of the Rotary valve penetrated. At the ends of the length section is a paragraph with an enlarged diameter provided that not through the hole can.

To make it, it would be possible to split the firing pin, insert a part into the bore of the rotary valve and then assemble the firing pin.

However, the material of the rotary valve is preferred by permanent deformation or by resilient Deformation on the reduced cross section of the length section adapted, which is a particularly simple Assembly and reliable captivity results. To facilitate the elastic or plastic deformation are radial slots formed by the bore of the rotary valve.

The rotary valve can have openings or axial projections have, which engage in projections on the closure. Prefers (Claim 7), however, are peripheral tabs on the rotary valve formed, which extend radially outwards, in any rotational position of the slide within the cross-section of the closure lie and in the security position on Reach behind the attached protrusions from the front. This is one that is as large as possible, but also simple design of the rotary valve can be achieved, so that it is readily accessible, but not in any Position impair the function of the closure can.

This also makes it possible to remove the rotary valve from one Form spring washer (claim 8), the approximately Punching out can be produced particularly inexpensively can.

This spring washer is preferred with respect to the vertical axis symmetrical (claim 9). This is particularly beneficial for a weapon with a selectable cartridge ejection direction, because there the ejector either on one or other side in the closure. The symmetry mentioned also has the advantage that a wrong Assembly due to the misaligned spring washer not possible. Because of the symmetry of the The spring washer does not matter which one Their surfaces face them forwards or backwards has.

Preferably (claim 10), the spring washer has two short circumferential tabs at the bottom and one in the middle long circumferential flap upwards. The long perimeter strap grips - from the front and under spring tension the spring washer - into a recess, at the front of a projection of the closure carrier is trained. The long circumferential tab must be unlocked only with your finger from the back to the front to be pushed forward out of the latch to become. An oblique load on the long circumferential tab the spring washer then turns with the user's finger so far that it frees itself from all protrusions.

The object of the invention is explained in more detail with reference to an embodiment and the accompanying drawing. The drawing shows:

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,

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, and

Fig. 4 is a view as in Fig. 3, but with the firing pin holder unlocked.

In the drawing, a closure is shown, which consists of a Closure carrier 1 and a closure head 3 is formed. Closure carrier 1 and closure head 3 have a center Longitudinal bore in which a firing pin 5 sits, the is pushed back by a firing pin spring 7.

An ejector 9 is provided parallel to the firing pin 5, the one on the left next to the firing pin 5 the closure 1, 3 penetrates. At the very edge of the breech head 3 is an extractor claw 11 at the front right appropriate.

The firing pin 5 holds an unspecified one Control pin in its position. If the firing pin 5 is removed, the control pin can be removed and the Closure head 3 can be removed from the closure carrier 1 become. When reassembling, the locking head can 3 can be installed in two different positions, and either with the extractor claw 11 on the left and the Ejector 9 right (cartridge ejection to the left) or how shown with the extractor claw 11 on the right and the ejector 9 left (cartridge ejection to the right). Subsequently the control pin is reinserted and with the Firing pin 5 secured.

To attach the firing pin 5, this has on his rear end of a length section 17, the after in front by a paragraph 19 and in the back by a Thickening 21 is limited, both of which are larger Have diameters than the longitudinal section 17.

An approximately Y-shaped, flat locking washer 23 made of spring sheet has one at the intersection of their legs Drilling on. The legs of two short 27th and a long 29 circumferential tab formed. The center line the long peripheral tab 29 lies on the vertical axis the weapon and forms an axis of symmetry for the locking washer 23. From the hole in the locking washer 23 radially go out three short slots 25, between them Material tongues stop coming out of the plane of the lock washer 23 can spring out. Concentric to Bore has the Y-shaped locking washer 23 in the area a section of the junction of their three legs with a circular arc-shaped peripheral edge 31.

The locking washer 23 with its bore from behind pressed here on the thickening 21. The material tongues between the slots 25 then dodge and let the thickening 21 through the (too small) Step through the hole. On length section 17 the material tongues spring back so that the locking washer 23 with its bore the length section 17 with encloses little play, so captive on the Firing pin 5 is attached, but its limited Axial movement is not hindered.

The locking washer 23 can be a securing position or take a release position. The security position is in Fig. 3 shown. In it the firing pin 5 is in the breech carrier 1 attached. The release position is in FIG. 4 shown. In it, the locking washer 23 is in hers Level at an angle of 45 ° to the securing position twisted and removable together with the firing pin 5.

At the back of the fastener carrier 1 are three projections 13, 15 arranged, which are complementary to the peripheral tabs 27, 29 of the locking washer 23 are. Each of the two lower projections 13 has one Circumferential groove. Both circumferential grooves are radially inward open and have approximately the same radius around the firing pin 5 on. In the circumferential direction is the distance between the two lower projections 13 dimensioned so that in the Release position of the locking plate 23 a short peripheral tab 27 remains within this distance and after can be lifted out at the back. In the secure position however, the radially outermost ends of the two engage short peripheral tabs 27 in the peripheral grooves of the lower Projections 13 a.

An upper projection assigned to the long peripheral tab 29 15 has a forward-facing surface in which a recess is made to the rear, which is the end the long peripheral tab 29 can accommodate. The reason of the The depression lies approximately in the plane of the rear side edges of the circumferential grooves in the lower protrusions 13.

The circumferential dimension of the upper projection 15 is chosen that the long peripheral tab 29 in the release position of the locking plate 23 in front of the upper projection 15 laterally has emerged and the lock washer 23 with the firing pin 5 removed from the breech carrier 1 can be.

On the other hand, the long circumferential tab sits in the secured position 29 (if necessary with spring preload) in the recess of the upper projection 15. The side faces of this Indentation prevent it from locking washer 23 is rotated unintentionally.

However, if the long circumferential tab 29 from behind the finger (springy) bent forward or pressed then it leaves the intervention in the recess and can be rotated 45 ° clockwise or against it become. So the lock washer 23 comes in their release position in which all circumferential tabs 27, 29 of the corresponding projections 13, 15 come free.

The locking washer 23 is not only captive in turn, because it is permanently attached to the firing pin 5 is. The created from disc 23 and firing pin 5 Component is also so bulky that it (in contrast to firing pin 5 alone) not easily lost can go.

With a movement of the closure 1, 3 that particularly in the continuous fire can be intense and persistent no force components in the circumferential direction. It exists so far there is no danger that the recess in the upper Projection 15 worn out. Furthermore, the mass of the lock washer 23, which is made of thin spring plate or a thin resilient plastic plate is so low that the long peripheral tab 29 is not due to mass forces from the locking recess in the upper projection 15 pops out. For safety's sake, however, the bottom of this Resting recess so far in front of the plane that defined by the circumferential grooves in the lower projections 13 is that the long circumferential tab 29 with stronger Preload sits in its recess.
