Abstract

The hand gun has a trigger mechanism and a cock (5). It also has a clamping piece (15) acted on by a striking spring and driving the cock. The clamping piece has an additional lock (17) which is independent of the trigger mechanism. This lock can selectively secure the clamping piece in its stressed position.

Description

The invention relates to a handgun with a Trigger device, a tap and one of these separate clamping piece, on which an impact spring acts and which in turn affects the tap.

Such a handgun is from DE 197 32 857 C1 known.

Terms such as "top", "front", etc., the following used to refer to the weapon in normal, horizontal stop; "front" points in the direction of the shot.

A pistol has recently become known (Daewoo, Korea), in which the previously known tap in two parts is trained and from an actual tap and one Clamp exists. The tap has a handle that is available for tensioning. The clamping piece is with the Combination spring connected and driven by this. The Clamp acts on the tap. The trigger device this gun works by means of the cocking device (Double-action facility) on the tap while the Rest, which trigger the shot when the weapon is cocked should (single-action rest) is arranged on the clamping piece.

When the cocking trigger is actuated, the tap turns on the tensioner moves and takes with it at the rear. When pressed the trigger on a previously tensioned clamping piece strikes this and takes the tap with him.

The advantage of this arrangement is that you can the cocked clamping piece simply put it back in its can move the front end position; it's just a discontinued one Overcome frictional resistance. So the tap stays e.g. do not hang there when pulling the gun out of clothing. Nevertheless, the shot is only the low trigger weight to overcome the cocked weapon. When moving the Hahnes with tensioned clamping piece against the set The trigger moves back into frictional resistance the front position (double-action position) that the corresponds to the cocked weapon. When pulling off is with the deduction only the low friction resistance mentioned overcome until the trigger then with the tap moved back Triggers and the shot is triggered.

In the position just described (clamping piece clamped, Cock in front) the trigger is in the front position (Double-action trigger position) and is therefore from the pressure point (Single-action trigger position) far away, making a far there is a higher level of security than with a conventional, cocked weapon. Nevertheless, it is conceivable that the tension Tension piece unintentionally out of the rest (single-action rest) is released, for example as a result of a violent vibration such as when the weapon falls onto hard ground. Though then strikes the tension piece after putting his Stroke path against the one resting in its forward position Hahn, which has a considerable mass, but this one could fire a cartridge in the worst case. Even if the tap should then be secured, the Failure of the fuse to trigger the cartridge.

This problem was exacerbated by the fact that many User the trigger of the known pistol only in Use case of a cartridge failure, but the usual one Guide the weapon, do not unclamp the clamping piece, but just push the tap forward. So you run it cocked weapon. But that should basically be done by the Hahn should actually be prevented.

Proceeding from this, the invention aims to: Security with a weapon of the type mentioned at the beginning improve.

This object is achieved in that of such a weapon an additional one, of the Trigger device independent fuse is provided, the sets the clamping piece directly (claim 1). The The above-mentioned problem is thus eliminated.

Percussion safeguards are known, but so far the hammer was a handle with a handle of course, the entire tap was always replaced by the Strike protection set. It would therefore be obvious been, even with the generic weapon the cock, like known to fix with a striking device, not the separate clamping piece. It actually shows the preferred one Embodiment shown in the accompanying drawing is shown, in addition to the invention Clamping device protection also an impact piece protection on.

The advantage of the invention is that Knocking off the clamping piece not made ineffective, but is prevented from the outset, so that an optimal Security is guaranteed.

The clamping piece fuse according to the invention can with a other existing fuse be coupled so that when Operate this usual fuse also Clamping fuse according to the invention inserted or released becomes. The clamping piece fuse according to the invention could also be connected to the magazine shaft and as Magazine lock act so that they automatically indented when the magazine is removed.

The clamping piece fuse according to the invention is for this set up to fix the tensioned clamping piece; she but can be modified so that it also does so can be used, the untensioned clamping piece to determine and with a suitably trained weapon, such as a self-loading pistol, also retracting the Hahnes and thus to prevent the closure movement. If about the actuation of the invention Clamping device security via a lock or similar Establishment is carried out which the weapon before unauthorized Protects use, then prevents setting the unstressed clamping piece also at the same time that the weapon is loaded or unloaded.

According to an advantageous embodiment of the invention the clamping piece fuse according to the invention with its own Operating handle provided so that it is independent of other fuses can be operated and released (Claim 2). This does not preclude them not is additionally coupled with other fuses and for example, indented automatically when that Magazine is removed.

This operating handle can be used as a standard safety wing or advantageously as a handle securing bracket be trained so that the weapon is automatically secured is when put down and automatic is unlocked when the handle, the fore-end or the like. is firmly gripped by hand.

A particularly advantageous embodiment of the invention but is that the operating handle of the Clamping device according to the invention in the range of motion of the tap or a handle of the tap is attached (Claim 3). If the shooter with the thumb after the tap grasps him in his front with tensioned clamping piece Bring position, then he can with his thumb if necessary also operate the operating handle and the Engage the clamping piece fuse according to the invention. Vice versa a shooter can then, when he reaches for the cock, to withdraw it and thereby pull the trigger into the single-action position to move, even the operating handle capture and thereby the clamping piece protection ineffective make or unlock.

The clamping piece lock can be designed as an eccentric shaft be, which passes through the handle and when twisted engages under a projection of the clamping piece. It can Clamping piece can even be lifted out of the catch, so that there is no risk that the clamping piece at Unlock dismisses.

In a preferred embodiment, the Operating handle but at the end of an angle lever, the order a transverse axis is pivotable, the other end of the Angle lever with a projection on the circumference of the clamping piece can be brought into engagement (claim 4). The angle lever reaches around the clamping piece and reaches it on the one hand a position where a convenient way for the Arrangement of the projection exists. On the other hand, achieved the angle lever with the operating handle is special favorable range in the range of movement of the handle Cock. This operating handle can also be used as narrow, corrugated projection be formed, the next the tap is arranged and with the tip of the thumb User is easy to operate, even if this should wear thick gloves.

The length of the two legs of the bell crank will be like this chosen that a reasonable range of motion for the Handle is reached. The formation of the two legs is such that their mass, based on the distance to the Transverse axis, is substantially the same, so that one on the Gun applied mass force (for example, on impact hard surface) no tilting movement in the angle lever can trigger.

As far as the position of the transverse axis is concerned, it is preferred between the axis of the tensioned clamping piece and one Tangent to the circumference of the clamping piece in the projection (Claim 5). The power from the lead to the Angle lever is exerted, which engages behind the projection, thus has a component that seeks the Pull the angle lever against the clamping piece. It is thus a particularly reliable security intervention guaranteed.

The operating handle is preferably located next to the side Hahn and the axis of the angle lever is preferably above that of the clamping piece (claim 6); is a situation for that Angle lever on the side next to the parts of the trigger and Teeing facility found that their training is not limited. In addition, the operating direction corresponds to Control handle of the movement of the tap: the arched forward and upward movement causes this Secure, the backward movement unlocking.

The angle lever can be arranged accordingly Transverse axis are prevented from the projection of the Clamp to get free because it engages with this is pressed. The bell crank could, however, out of his unlocked position behind the said lead come up with it if it were too smooth.

This interference could be prevented by Angle lever gives a certain frictional resistance, which prevents the angle lever from being moved unintentionally becomes.

In a preferred embodiment, the angle lever however assigned at least one rest (claim 7), the him at least in the release position (unsecured position) holds. Preferably, the angle lever is also in the Secure position can be determined by a rest. So is excluded that the position of the angle lever is unintentional is changed, for example by touching the clothes at Pulling the gun. The angle lever can advantageously instead or additionally loaded with a spring that always presses it against the clamping piece. This Spring is preferably designed as a leaf spring and can thus used under the tightest spatial conditions become.

So the invention creates an additional one Security device, the special, generic Weapons provides additional security, but without the Operation of these weapons unduly difficult or difficult To delay emergency.

The object of the invention is explained in more detail using an exemplary embodiment. The attached schematic drawing shows:

Fig. 1

a longitudinal section through the rear part of the handle of a self-loading pistol, parts being omitted for the sake of simplicity, with the clamping piece relaxed, and

Fig. 2

the longitudinal section of FIG. 1, but with a tensioned clamping piece and further simplified.

In both figures, the rear part of a handle 1 a self-loading pistol shown in longitudinal section. This Handle 1 has a recess 3 into which the tap 5 during its pivoting movement about an axis 7 of the tap 5 can immerse. The axis 7 is for the sake of simplicity not shown hatched. The tap 5 has a handle 9 on which when pivoting the tap 5 in the Recess 3 protrudes beyond the handle 1 to the rear and can be gripped by the user's thumb when this holds the handle 1 ready to fire in hand.

When it swivels forward, the tap 5 can open open a firing pin 11 and so a cartridge ignite (not shown). In the drawing, the tap is 5 however in a position not so far forward secured. The cock 5 is namely on a catch pawl 13th on, which prevents the tap 5 the firing pin 11th can reach. This catch pawl 13 forms one "Striking piece protection", as previously in technology was known.

In a lower recess of the cock 5 sits Clamping piece 15, which is also pivotable about the axis 7. The clamping piece 15 is by a (not shown) Shock spring loaded in the direction of the tap 5. The clamping piece 15 can be in a tensioned position Trigger lock occur, which is not shown. In Fig. 1, the clamping piece 15 is tensioned or untensioned and therefore sits in the recess on the tap 5.

On a transverse axis 19, which is in front of and above axis 7, however parallel to this, attached in the handle 1, sits pivotable about an angle lever 17 with two to each other arranged at right angles and almost the same length Thighs. The angle lever 17 is approximately in the range of Angle between the two legs with a hole provided and swivels with it on the transverse axis 19th

The angle lever 17 is by a leaf spring (not shown) constantly towards the clamping piece 15 loaded.

The one leg of the angle lever 17 pointing downward has an engagement nose 25 on its rear edge, which is set up in a projection 21 of the to engage tensioned clamping piece 15 (see FIG. 2). At the End of the other, rear - facing leg of the Angle lever 17 is a bent down on the Web with a corrugation on the outside, which serves as an operating handle 23.

The backward, approximately horizontal leg of the Angle lever 17 is shown broken through in FIG to show the catch pawl 13.

The angle lever 17 is by a (not shown) Locking device in the position shown in Fig. 1 held so that the pivoting movement of the clamping piece 15th can take place freely.

In the tensioned position of the Clamping piece 15 is the angle lever 17 in its shown Location set. The operating handle 23 can therefore not be moved.

If the clamping piece 15 is tensioned against it, then there is whose projection 21 is exactly behind the engaging nose 25 now the operating handle 23 pushed up, then engages under the engaging nose 25 and holds the projection 21 so the clamping piece 15 firmly (as shown in Fig. 2).

Now, for some reason, the clamping piece 15 comes loose the projection 21 tries to engage the engaging nose 25 Pull up clamping piece 15. The engagement nose 25 remains therefore in their tense situation. In addition, another (Not shown) locking device may be provided, the Engagement between the engagement nose 25 and projection 21 still further secures.

The operating handle 23 is only a narrow, corrugated one Web, which next to the handle 9 of the tap 5 in the Recess 3 is arranged, but hardly from this protrudes behind. This ensures that the Operating handle when handling the weapon is not is accidentally pressed, for example when pulling out the Gun out of your clothes or bag. On the other hand, the Operating handle 23 effortlessly with the user's thumb be operated, if necessary when operating the handle 9 of the tap 5, even if the operating hand is a thick one Wearing glove.

The clamping device fuse shown is in the present Example built into a handgun, but could can also be provided for a long gun. It has to be also not, as shown, to act as a self-loading weapon, but could just as easily be a repeating weapon act, or also a single loader or a multi-barrel weapon.
