Safety device for firearms

The invention relates generally to firearms and in particular a safety device to prevent firing pin actuation during reloading

In various weapons it has been found that the firing pin in the forward position as a result of a A number of factors are jammed, e.g. by powder residues, dirt accumulation and even odor relatively low eccentricity between the firing pin and its guidance by a locking piece. It was also observed that the firing pin sometimes jams at a sufficient distance in front of the safety lock and this then can be brought into the "secured" position to effectively lock the firing pin when its firing head has been driven forward out of the firing pin guide. In this case e.g. during reloading, with a cartridge usually being hand-loaded into the chamber, an extremely dangerous situation a. The person who handles the weapon would have no reason to fear that the inserted cartridge was inadvertently could be fired, especially because the safety lock is on "secured". However, unintentional firing under these circumstances is not only during the closure of the chamber

309818/0245

possible, but most likely this will happen before the chamber is completely closed because the bolt is locked in a firing position. This not only leads to damage to the weapon, but If the cartridge explodes, any pereon in the immediate vicinity of the weapon can be fatal.

Accordingly, it is a primary purpose of the invention to provide an improved safety device for firearms Provide as much as possible to reduce the risk of accidental firing during reloading to decrease.

Another purpose of the invention is to provide a safety device of the type that includes a constant control of the firing pin under normal circumstances enables and is particularly suitable, the dismantling of the firing pin and that connected to it To simplify components »

Purpose, objects, features and advantages of the invention are expressed by the following description. the The invention will now be explained in more detail with reference to the drawing reproducing it, for example,

namely shows

Fig. 1 is a partly broken away and partly im.Querschnitt illustrated side view of a pistol in which the invention is incorporated,

FIG. 2 is a partially broken away sectional view along the line 2-2 of FIGS. 1 and

3 is an isometric view of a firing pin stop according to this invention;

In Fig. 1, a Toil a gun 10 is shown which CForm a preferred Ausführun ^ to the invention, however, is t, rfindung to other firearms types, such as revolver with clamping interruption or other weapons suitable which ^are equipped with inertia-firing pin · 3098 18/0265

According to the drawing, the gun 10 has a longitudinal direction attached locking piece or slide assembly 1.2, which consists of a slide 14 and a barrel 16, the for forward and backward movement in the longitudinal direction on Handle 18 are mounted. The gun 10 can be used as a automatic pistol of a known type with magazine loading and gas recoil, in which the combustion gases when firing a cartridge located in the chamber 20 of the barrel 16, the slide assembly Let it snap backwards to find a used bullet case to automatically pull out and eject and a spring held cock 22 during the backward movement of the slide 14- to be tensioned in relation to the barrel 16 and to the handle 18.

With the opposite movement of the slide in C5 a forward position to re-engage the barrel 16 to leave and to make the pistol 10 ready for operation again for the firing of the next cartridge, the pulls Slide 14 - automatically the top cartridge out of a magazine, not shown, and puts it in the Chamber in barrel 16. When the trigger is pressed, the hammer 22 falls down, and a firing pin 24, as in FIG Fig. 1 shown is driven in the longitudinal direction forwards to a primer (not shown) on the in the Chamber inserted cartridge to ignite and the above-described backward movement of the recoil device to bring about automatically.

The firing pin 24- lies in a longitudinal direction extending guide 26 within barrel 14 and is for back and forth movement between a rear Operational end position shown by broken lines at point 28 and a forward projectile firing position; shown in solid lines in Fig. 1 is set. The firing pin 24 shown is an inertia firing pin, in which the hammer has to strike fully in order to move it out of its rear end position to drive into its forward projectile firing position, The firing pin 24 is by means of a spiral spring 30,

309818/0246

which lies in the guide 26 is constantly pushed backwards into its rear operating end position. In each of the spring 30 presses against the slide 14 and lies in the front, narrower part of the guide 26 next to the barrel chamber 20, and opposite in the spring 30 presses against a round collar f> 2, which the Firing pin 24 in dor I'd do framed between his two Knderi.

A known pivotable safety lock 34 is built into the barrel 14 at the far rear end of the firing pin guide 26, which rotates about an axis which is transverse to the longitudinal axis of the slide 14. The pivotable safety lock A- can be operated in the tensioned state in the usual way by manual manipulation of an operating lever (not shown) between an "unlocked" position (shown in FIG. 1) and a "secured" position, whereby it is in the "secured" position in a position shown in the drawing in a clockwise direction, and a solid metal piece of the pivoting safety lock;) 4 is between the dome barge 22 and dome firing pin 24 that it does not hit any Hahns on the firing pin prevented.

Should the firing pin 24 for any reason jam within its guide 26 when the firing pin head 24Λ has been driven forward through the guide 26 and the firing pin 24 is overall in front of the safety lock ? 4, a cartridge could be manually inserted into chamber 20, e.g. normal reloading when the carriage 14 is in is withdrawn with respect to the handle 18, and the Safety lock; 54 could be in "face" position brought, and the firing pin 24 in its forward firing position actually lock. In this case someone might not be aware of the existing danger being aware and believing that the monkey is fully secured, the slide 14 would then in the usual manner solved to preclose the barrel chamber 20, so v.-ürde the carriage 14 by its drive, not shown:; - 3 0 9818/0245

spring driven forward, and the cartridge in the chamber would be similar to a submachine gun fired immediately. This would result in the weapon being fired when the slide 14 and barrel 16 are still in the unlocked position to each other, before chamber 20 is closed.

To avoid any danger of such a hasty rush of the firing pin 24 in relation to the safety lock 34 to a large extent, the firing pin 24 remaining overall in a position in front of the safety lock ^ 4, the firing pin 24 is on the Drawing with a middle piece 3 & shown, whose Cross-section in relation to the collar 32 is smaller, as well with a coaxial round collar attached to the rear part 385 which has the same diameter as collar 32 and serves as a radial stop 40, in which a lock or a latch 42 can engage, which is above the guide is built into the carriage 14 to control the firing pin and to ensure that it is under normal Circumstances relating to the security shutter 34 constantly is in the normal operating position.

The bolt 42 is held in a relatively large bolt chamber 44 with a rectangular cross-section, which, according to the drawing, is connected to the firing pin guide 26, dix'ekt is arranged below a dovetail-shaped recess 46 and protrudes transversely over the rear surface of the slide 14, with a corresponding shaped support surface 48 in the visor 50, which is mounted within the recess in the carriage 14 according to the drawing ₀

In the lower rear part of the brick wall 42 is a Cut out milled out so that a rearward facing vertically running smooth bearing surface 54 is created, in dio the radial projection: 4ü of the firing pin 24 engages; on can to limit its forward movement and prevent that the firing pin 24 over the front Goschoßabfc- uerstellunc or the anterior, in Fig, I in Γ. 09818/0245

operating end position shown in solid lines. The stop surface 54- of the bolt 4-2 has a according to the drawing (Fig. 2) in the middle of the lower edge arcuate recess 56, which the surface Xorm dos thinner l-dttelctücks 36 of the firing pin 24 between the collars 32 and 38 corresponds to enable that the firing pin 24- unhindered by the impact ■ the Hahns snaps forward and is driven back by the pressure of his spring 30 without it being clamped on the handle 4-2,

•• Venn the .'aim 22 in his in the drawing Is in the stop position, the firing pin 24-normally against the hammer 22, the firing pin 24 - here for illustration in its projectile firing position is shown. When the cock 22 is cocked, the firing pin 24- is in a certain amount due to the pressure of its spring Distance from its stop position against the cock 22 driven backwards until it hits the safety lock 34- strikes.

In any case, the liiegel 4-2 will, under normal conditions, always hold the rear end of the firing pin 24- in a straight line with a correspondingly shaped firing pin opening 58, which is jammed in the safety lock 34-, and hold it there, regardless of whether the safety lock is set to "secured" or "unlocked", and thereby prevents the firing pin 24 from being driven too far forward in relation to its safety lock 34. If the firing pin 24 should be clamped in a forward position within its guide 26, the locking construction described above, which is built into the "V / monkey" according to the invention, ensures that the firing pin 24 is unintentionally due to the setting of the safety lock .34 - is locked in the "secured" position, but rather it is for a backward movement into the firing pin opening 58 by any pressure exerted on the firing pin head 24A when it shoots out past the guide 26

set within the outline of the safety lock 34- As a result, there is no risk of accidentally firing a manually inserted one into the chamber Cartridge during reloading when the slide is released 14 considerably reduced. Any jamming of firing pin 24 in a forward position would normally cause its firing head 24A to be directed backwards on contact with the cartridge inserted in the chamber, without igniting the cartridge's primer.

To be able to safely install the bolt 42 and also d: s Taking apart the firing pin 2 * - and the pivoting one Safety lock 3 ^ - to facilitate is a . Fixed mounting bolt 60 installed, which is in a preferred Embodiment forms an integral part of the bolt 42 and in the opposite direction to the lower arcuate edge 56 of the bolt 42 protrudes downwards, in order to be able to be inserted into a vertical recess 62 which, in relation to the retaining bolt 60 a slightly larger diameter and on the surface of the upper inner wall of the carriage 14 an exposed one Opening 64 has. A recess 66 is in the upper part of the latch 42 in a straight line with the protruding Halt,:. Retaining bolt 60 milled around one end of the spiral spring 68, the opposite end of which abuts against the support surface 48 of the visor 5 °.

In order to remove the firing pin 24 from the slide 14, the slide 14 is removed from the handle 18 so that the mounting pin 60 is exposed and can simply be pushed inwards to push the locking stop 54 upwards into the recess inside the bolt chamber 44, to the extent that it is possible to push the firing pin 24 forward into the guide against the pressure of its i'eder;? 0 so that the safety lock 34 can be pulled out of the slide 14 from the side . For this purpose, a Hanschette 70 at the rear "Jnde the striker 24 in the retracted bolt 42 may be additionally beneficial because \; hen the firing pin 309818/024 5

in this case is pushed forward, the cuff 70 can be placed in front of the bolt 42, the then, when it is released again, snaps into the sleeve 70 to temporarily put the firing pin in a To hold position in which he is not in connection with the safety preclusion 34, which then quickly and can be easily pulled out.

When the safety lock ^ A- is removed, the retaining bolt 60 of the latch 42 can be pushed in again, and the compressed spring 30 pushes the firing pin 24 backwards again so that it can be removed from the slide 14. In a preferred embodiment as shown in the drawing, the front side of the bolt 42 has a bevel 72 in order to make it easier for the firing pin 24 to be pulled out.

The assembly of firing pin 24 and safety lock y \ - is simply carried out in reverse order, a complete dismantling of bolt 42 and spring 50 from the bolt chamber 44 is done by pulling out the side and removing the visor 50 from the slide 14,

The spring-held firing pin lock according to this invention enables constant control of the Firing pin and effectively largely reduces any risk of the firing pin advancing too far and possible fatal consequences when reloading the weapon. A spring-operated firing pin lock of the The design described above is used to keep the firing pin in constant contact under all normal conditions to hold with the safety lock and protect every person handling the weapon against a false sense of security, when the security lock is set to "secured". In addition, the design includes that described Construction in which the bolt is installed below the visor attached to the slide, all the equipment required for this purpose that makes up the bolt
