Abstract

A firing pin control device for a small arm is disclosed. The small arm includes a hammer, a housing including a fixed part, a slide disposed in the housing, with the slide being moveable between an open position and a closed position, and a firing pin mounted to the slide and being moveable relative to the slide along a linear path between a first position in which contact between the firing pin and the hammer is prevented and a second position in which contact between the firing pin and the hammer is permitted. The firing pin control assembly includes a pair of sleeves mounted in the slide, with the firing pin being slidable relative to the sleeves. A forward one of the sleeves engages the firing pin and is moveable between a forward position in which the firing pin is disposed in the first position and a rearward position in which the firing pin is disposed in the second position. The firing pin control assembly includes a counterspring arranged to bias the forward sleeve toward the forward position. A portion of the sleeve cooperates with the fixed housing part to thereby move the firing pin to the second position in response to movement of the slide to the closed position.

Description

The invention relates to a handgun with a Lock moving into one for igniting one Cartridge fitted end position is movable, one in Closure along a trajectory movably mounted firing pin with a striker pin spring (1) loading it backwards and one Demolition device by a trigger device is triggered and is set up to ignite a Cartridge on the side facing away from this firing pin end aufzuschlagen and thereby the firing pin in his To spend ignition position. Such a weapon is out No. 1,363,040.

In the following used terms such as "top" o. The like. go out from the horizontal position of use of the weapon when Shot, wherein the weft direction points to "front" (in the Drawing to the left).

Many self-loading handguns have a tap provided that abschlägt when pressing the trigger and on the rear end of a firing pin hits the Closure interspersed and by a firing pin spring pushed backwards so that its rear end to a protrusion line protrudes from the shutter and its front end, the tip, at least around the Projection distance from the front face of the Lock is reset. At the serve of the cock on the rear end of the striker this is accelerates and moves due to its inertia against the force of the firing pin spring forward, where he out the face of the lock, the push bottom, with its Exit the tip and hit the primer of the cartridge can sit on the bottom of the shock from the front. Instead of a cock can also be provided a hammer, the not, as a cock is pivotable about a fixed axis, but e.g. guided in a straight-line movement path and is movable under load a striker. In the following is for the sake of simplicity, but without any Restriction, only spoken by a "cock".

To prevent the tap from knocking off already, open the firing pin end hits and the ignition of the cartridge caused before the shutter is completely closed is in the trigger means a breaker mechanism provided that the triggering connection between the Deduction and the cock only then produces or with continuous fire the cock only triggers when the shutter is full closed is. At the same time, this breaker mechanism becomes controlled by the position of the shutter, so that In principle, the delivery of a shot only possible is when the shutter is completely closed.

However, there may be manufacturing tolerances, pollution and / or wear on the interrupt mechanism or the breakage of a component so that this already the connection of trigger and cock or its triggering at Continuous fire then produces when the shutter is still open or unlocked or partially locked.

Based on this problem situation, the invention is the Task is to provide an additional device, the forcible triggering a shot only then allows if the shutter the cartridge sufficiently far introduced into the chamber.

This object is achieved by the features of Ansprüchs 1. It is the one independent of the trigger device, additional Device for preventing the by the Demolition device or the cock triggered movement of the Firing pin provided in its firing position.

This facility is set up to handle this movement Only allow firing pin in its firing position, if the shutter has reached its end position and thus the Cartridge so far introduced into the chamber, that this is sufficiently supported.

Experience has shown that the Trigger mechanism, which is actually the premature firing a cartridge should prevent, from the most diverse Reasons not able to do so with the utmost reliability is. The invention therefore provides for a separate Device whose purpose is to use the firing pin for so long to prevent reaching its ignition position until the shutter reached its final position until the security measure. in this connection it is clear to those skilled in the art that the end position no point along the movement distance of the shutter is, but a Tolerance field, which is very narrow.

In this invention, it is also ensured that z. B. by bouncing the shutter a certain opening of the However, the firing pin can occur immediately is controlled from its loading area of the tap.

The, additional facility could be about consist of a rocker arm, the pivoting in the closure is stored by a spring with his one leg in locking engagement with the closure is depressible and with its other end on the front face or one Side surface of the closure over this protrudes. in the Movement path of this protruding leg is on the barrel or on the housing a stop surface provided against the when closing the shutter this protruding Thigh starts while doing the other leg of the Rocker arm out of engagement with the firing pin lifts. The Arrangement of the abutment surface is such that the Firing pin is released only when the shutter has reached the tolerance field of its final position.

However, such a mechanism is high forces exposed, which act on sliding moving parts and thus can cause significant wear; In particular, this mechanism can be achieved by the action of Knockdown device are knocked out.

According to the invention is therefore further provided, the firing pin then, if ignition should be prevented from the range of motion to spend the tee-off facility.

It would be too possible, the firing point set up for ignition from a position opposite the primer of the cartridge remove, but then could be a knock off the Demolition device may damage the firing pin to lead.

Although the firing pin could be tilted so that it with its rear end transverse to its direction of movement is offset, as known from certain backups ago is. According to the invention but the firing pin is such Measure moved forward, that he reliably still behind its firing position lies, but so far in the lock dips in that his rear end before contact with the Rooster or a hammer by training of the Closure, preferably the rear end face of the Closure, is protected. This embodiment is especially with a weapon to prefer, where the cock is completely within the housing, so that not the There is a risk that a foreign body between cock and Firing pin device and then still for an ignition could provide.

The firing pin could in the described security situation by the closing spring acting on the closure be spent. However, according to the invention is one Provided counter spring, extending between shutter and Striker supported, but this only up in his Can press security. The spring force of the opposing spring This is higher than that of the firing pin spring used. In the forward movement of the shutter occurs just before it reaches its final position, the Counter spring with a stationary housing education, about a housing projection o. The like., Engages and breaks thereby their action on the firing pin off, the now as far as moved back by the action of his firing pin spring can be that the cock then unhindered on the Can strike the firing pin.

The following prior art is known:

• einem Verschluß, der beweglich in einem Gehäuse in eine für das Zünden einer Patrone eingerichtete Endlage beweglich ist,
• einem im Verschluß längs einer geradlinigen Bewegungsbahn beweglich gelagerten Schlagbolzen mit einer diesen nach hinten belastenden Schlagbolzenfeder, und
• einer Abschlageinrichtung, die von einer Abzugseinrichtung auslösbar ist und dazu eingerichtet ist, zum Zünden einer Patrone auf das von dieser abgewandte Schlagbolzenende aufzuschlagen und dadurch den Schlagbolzen in seine Zündlage zu verbringen.

US 1 363 040 A, which describes a gun, with

• a closure which is movably movable in a housing into an end position adapted for firing a cartridge,
• a firing pin movably mounted in the shutter along a rectilinear trajectory with a firing pin spring loading it backwards, and
• a knock-off device, which is triggered by a trigger device and is adapted to strike for igniting a cartridge on the side facing away from this firing pin end and thereby spend the firing pin in its firing position.

• eine von der Abzugseinrichtung unabhängige, zusätzliche Einrichtung zum Verhindern der durch die Abschlageinrichtung ausgelösten Bewegung des Schlagbolzens in die Zündlage vorgesehen, und
• die Einrichtung dazu eingerichtet, die Bewegung des Schlagbolzens in seine Zündlage erst dann zuzulassen, wenn der Verschluß seine Endlage erreicht hat.

This pistol is

• an independent of the trigger device, additional device for preventing the triggered by the knock-off movement of the firing pin provided in the ignition position, and
• the device adapted to allow the movement of the firing pin in its firing position only when the shutter has reached its end position.

In this known pistol but is not the device formed as a counter-spring, with a housing-fixed Training cooperates.

From GB5124 A.D. 1914 Although a counter spring is known, but not with a housing-proof training interacts.

The stationary housing education could be about as indentation be made of a sheet formed housing; However, this housing training is preferred as its own Part formed, which accordingly consists of a for its purpose optimized, highly wear-resistant material can be made. This separate component can be permanently attached in the housing, such as by composite casting, but can also be releasably attached, so that if it worn or damaged, without further ado can be replaced by a new component or even before the final installation can be fitted. Is preferred this component provided with an engagement training, the engages in a counter training on the barrel, so that the critical distance between the back end of the barrel and thus the cartridge chamber and the surface or edge of the Component that cancels the action of the opposing spring effortlessly can be maintained with a very narrow tolerance field.

Preferably, said separate component is as Cartridge ejector formed; anyway off wear-resistant material must be formed and on the According to the invention, a surface or edge is formed, the for catching the opposing spring or its associated part serves. It can thus be the said, separate component be provided optimal material without that, therefore an additional part of the weapon is required. It is therefore possible, a weapon of the type mentioned in a most economical way with a novel Safety device to be provided by the Discharge device is completely independent, and therefore also of the summation of tolerances and the wear at a trigger device are ultimately difficult to avoid.

The object of the invention will be explained in more detail with reference to the accompanying schematic drawing, for example; in this shows:

1 is a front and rear broken plan view of a submachine gun, in longitudinal section, during the closing movement of the closure and with partially inserted into the cartridge chamber cartridge,

2 is a view as in Fig. 1, but with almost inserted into the chamber cartridge,

3 is a view as in Fig. 1 or 2, but ready to fire and with fully inserted into the chamber cartridge,

Fig. 4 is a representation as in Fig. 1 to 3, but at the shot, and

Fig. 5 is a longitudinal elevation through the closure of the submachine gun.

The submachine gun shown in Figs. 1 to 4 has Housing 11, in which a barrel 13 is attached to the his rear end has a cartridge chamber in the a cartridge 14 is insertable. Behind the barrel 13 is a in the longitudinal direction movable, unlocked Closure 15 (ground closure) arranged in the housing 11th is guided and by a (not shown) closing spring pushed forward and against the barrel 13. Laterally from the shutter 15, when this in its front End position is an ejection window 12 in the housing 11th educated.

The shutter 15, which is also shown in Fig. 5, is in the middle of the length of a firing pin 3 interspersed, which loads a firing pin spring 1 to the rear in such a way, that he seeks to take a position in which the Rear striker end 10 from the rear End face of the closure 15 by a supernatant Y after protrudes behind (Fig. 3).

Below the lock 15 and behind the front End position is a cock 9 pivotally mounted, which in Figs. 3 and 4 is indicated only very schematically. This cock 9 can be from a clamping position, in which its upper end with Distance behind the front end position of the closure is arranged (Fig. 3) in a tee-off position, which is shown in Fig. 4 and in which the cock 9 on the to the rear beyond the closure 15 projecting, rear Striker end 10 hits; This will be the Firing pin 3 thrown forward, hits the Primer of the cartridge 14 and fires this off (Fig. 4). Such a weapon is from the state of the art known.

In the closure 15 is also an extractor and Safety device in the form of a leaf spring 16th attached, whose rear end has a projection, engages in front of an end collar 20 of the firing pin 3 and prevents this from moving forward. The tee off Cock 9 meets an inclined surface on the leaf spring 16th and deflects them so that their projection from the Engagement with the collar 20 is moved and only then Firing pin immediately before the hammer is hit 9 is released. This leaf spring 16 is in German Patent application 197 02 374.6-15 described by the applicant; the disclosure of this patent application is by the Reference expressly included in the present documentation added. In the invention, this leaf spring is the 16th modified so that they do not the firing pin 3 in completely fixed his backward situation, but one to him certain mobility (over the route X + Y) in Leads longitudinally forward. The firing pin 3 is from the leaf spring 16, however, still prevented with its tip over the front face of the Fastener 15 move out, as long as not the cock 9 by its knocking off the leaf spring 16 from the engagement with the firing pin 3 has pressed. The front end of the Leaf spring 16 is designed as an extractor.

On the leaf spring 16 opposite longitudinal side the closure has a in the front end face opening longitudinal groove 18, in which a Ausstoßervorsprung 17 engages the stationary at a, in the housing 11th fixed engaging part 8 is formed, which as Sheet steel component is formed, with its front End in a recess in the outside of the barrel 13 engages near the rear end. When the Closure 15 after a shot with the empty cartridge case moved back, the longitudinal groove 18 passes over the projection 17th backwards until the bottom of the cartridge case against the Leading edge 19 of the projection 17 meets and thereby is ejected, passing through the ejection window 12th is ejected.

The firing pin 3 points, seen from the front to the rear (in the drawing from left to right), a thin point on, subsequently a thicker, but slender shaft, the approximately to the middle of the length extension of the firing pin 3 ranges, followed by a thickened, cylindrical Section 21 and finally the already mentioned Endbund 20. The firing pin spring 1 is on the slender shaft guided and supported with its rear end on the Paragraph, which marks the transition between the slender stem and the thickened portion 21 forms.

From the front are successively a stop piece. 6 with its longitudinal through-hole, a helical Counter spring 5 and a sleeve 4 with its LÄngs through-bore pushed onto the firing pin 3 and with slight compression of the opposing spring 5 to the rear pressed; then a locking ring 2 attached, which sits in an annular groove, which is in the range of Transition between the shaft and the thickened section 21 of the bolt 3 is introduced into this. This Circlip 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 one lateral projection on, which is guided in the longitudinal groove 18 is; In addition, the stop piece 6 is stationary in the lock 15 held by a mounting pin 7. The sleeve 4 has, starting from the rear end surface, a Blind hole on, as well as the stopper piece 6, in which the blind bore from the front end surface starting. The Counter spring 5 penetrates into each of the blind holes and rests on the respective bore end face. In addition, the sleeve 4 sits with its front end surface a paragraph in the longitudinal bore in the closure 15. The Striker pin 1 is supported by its front end another paragraph in said longitudinal bore from, with its rear end on the heel of the firing pin.

The opposing spring 5 is stronger than the firing pin spring 1, so that the opposing spring 5 is always the sleeve 4 against the effect seeks to push the firing pin spring 1 forward. If the closure is e.g. removed from the weapon, as in Fig. 5, then the sleeve 4 sits on the associated Paragraph of the closure longitudinal bore on and presses the Circlip 2 and thus the firing pin 3 forward, so that the rear firing pin end 10 by the dimension X towards the rear end of the shutter 15 forward is offset. In this position of the Schagbolzens 3, the e.g. is shown in Fig. 2, the tap 9 hits when knocked off on the rear surface of the shutter 15, without the rear striker end 10 to achieve.

On the inside of the ejection window the housing 11 has a stationary engagement part 8 Sheet steel on, with a projection 17 in the longitudinal groove 18 of the shutter 15 is immersed. The leading edge 19 of this Projection 17 forms the ejector edge; if the shutter 15 with a cartridge 14 or an empty cartridge case moved backwards, then the edge of this hits Cartridge 14 or cartridge case on the ejection window 12 opposite side on the ejector edge 19 and is ejected by this.

On the opposite of the ejector edge 19 Rear side, the projection 17 has another Function edge, which is set up in the engage lateral projection of the sleeve 4 and then this and thus the sleeve 4 at another To prevent forward movement. This functional edge of the Engagement part 8 meets the lateral projection of Sleeve 4 on, when the shutter is still around the distance X + Y of his front end position is removed, which he shot should take.

The front end of the engaging part 8 engages in one Recess of the barrel 13, so that the rear Function edge of the projection 17 is always in fixed distance from the barrel 13 and thus of the The situation remains that the bottom of the cartridge 14 at gunpoint occupies.

In Fig. 1 ist der Verschluß 15 bei der Bewegung nach vorne gezeigt; er hat soeben eine Patrone 14 aus dem (vom Verschluß 15 verdeckten) Magazin entnommen, mit der Auszieherkaralle (am vorderen Ende der Blattfeder 16) erfaßt und führt sie nun in das Patronenlager des Laufes 13 ein.

The operation of the above-described arrangement will be described below.

In Fig. 1, the shutter 15 is shown in the movement forward; he has just taken a cartridge 14 from the (hidden by the shutter 15) magazine, detected with the extractor carousel (at the front end of the leaf spring 16) and now introduces it into the chamber of the barrel 13 a.

The leaf spring 16 engages with the projection in her rear area the collar 20 of the firing pin 3. The sleeve 4 is in its front end position and takes it over the locking ring 2 the firing pin 3 so far front, that is its rear end 10 around the distance X opposite the front end of the shutter 15 is moved forward is. Should now stop the tap 9 accidentally, then he would hit the back end of the shutter 15, but do not touch the firing pin 3. The in the longitudinal groove 18 guided lateral projection of the sleeve 4 is of the rear functional edge of the projection 17 of the Engaging part 8 removed by the distance Z, the Closure must cover at least, without the Cartridge 14 may be fired.

In Fig. 2, the shutter 15 has its position moved forward in Figure 1 by the distance Z; all in Closure 15 built-in parts have the same Relative layers on as in Fig. 1; the projection of the sleeve 4th has the functional edge of the projection 17 of the engaging part 8 reached.

In Fig. 3, the closure 15 with respect to that in Fig. 2 shown position around the distance X + Y moves forward and reaches its regulatory end position, in which the Cartridge 14 fully seated in the chamber. It was the Sleeve 4 during the last movement phase of the Functional edge of the projection 17 of the engagement part 8 held, so that they now from the corresponding paragraph in the Longitudinal bore which receives the firing pin 3, removed is. The firing pin spring 1 loads the circlip 2 and thus the firing pin 3 to the rear, so that the Circlip 2 still against the front face the sleeve 4 rests and the rear striker end 10 to the distance Y over the rear end of the shutter 15th protrudes to the rear.

In Fig. 4, the moment of firing of the cartridge 14 shown; the cock 9 is in the direction of the arrow up in moved his front end position, has over the Inclined surface at the rear end of the leaf spring 16 whose Projection from the path of movement of the Federal 20 of the Striker 3 moves and has to the rear Striker end 10 pitched; the firing pin 3 became accelerated by this impact and against the power of Firing pin spring 1 forward until hitting the Cartridge 14 primer moves. The opposing spring 5 acts not on the firing pin 3, as they over the Stopping piece 6 and the mounting pin 7 on the shutter 15th is supported. If now the shutter 15 through the Recoil of the fired cartridge 14 moves backwards, the cock 9 is stretched again and the firing pin 3 is pushed so far forward by the opposing spring 5, as shown in Figs. 1 and 2, as soon as the projection the sleeve 4 of the functional edge on the projection 17 of the Engaging part 8 is released. The guaranteed one-piece construction of the handle part 8 and its solid Intervention in the barrel 13 always a constant position of named functional edge.

It may be dirt between barrel 13 and shutter 15 accumulate, or a foreign body can go to the chamber arrive, which then prevents each that the shutter 15 his front end position can still reach quite. Here too decreases according to the supernatant Y, so that ultimately, when the closure situation is no longer the safe delivery of a shot ensured, no Shot can be made more.

In the following used terms such as "top" o. The like. go out from the horizontal position of use of the weapon when Shot, wherein the weft direction points to "front" (in the Drawing to the left).

Many self-loading handguns have a tap provided that abschlägt when pressing the trigger and on the rear end of a firing pin hits the freely flying firing pin interspersed and by a Striker pin spring is pressed backwards so that its rear end around a projection distance from the Shutter protrudes and its front end, the tip, at least the overhang distance from the front End face of the closure is reset. At the Serve the tap on the back end of the firing pin this is accelerated and moves due to its Mass inertia against the force of the firing pin spring front, where he is from the end face of the closure, the Shock floor, with its tip exits and, where appropriate on the primer of the cartridge meets the front sitting on the bottom of the shock.

To prevent the tap from knocking off already, open the firing pin end hits and the ignition of the cartridge caused before the shutter is completely closed is a breaker mechanism is provided, which is the triggering Connection between the trigger and the tap only then produces or with continuous fire the cock only then triggers, when the shutter is fully closed. This will be this Breaker mechanism by the position of the closure activated, so that basically the delivery of a shot only possible if the shutter completely closed is.

This applies to all unlocked weapons, but also for locked weapons.
