Description

Technical area

The invention relates to a firearm comprising a housing, an insertable into a receptacle of the magazine magazine, wherein the cartridges located in the magazine are biased by a Magazinzubringers towards a takeover opening, a movable relative to the housing closure for transporting cartridges from the takeover opening of the magazine in an in-housing cartridge chamber or for transporting the cartridge cases from the chamber to an ejection window and a pivotally or slidably disposed on the housing closure catch lever, which is held in cooperation with the Magazinzubringer the shutter with the magazine empty in a rear disengaged position.

State of the art

The currently common firearms, which are used for example by emergency forces around the world, have the following operation. When firing a cartridge pushes the recoil or the gas pressure, the closure, also called slide or Verschlußssstück backwards. In this case, the extractor attached to the closure (also called the extractor claw) pulls the empty cartridge case out of the cartridge chamber at the groove intended for this purpose. Also the "Handbook of Fist Firearms", Bock G. Weigel, XP002729838 discloses a firearm with a catch catcher.

In the further return, the sleeve held by the extractor hits the ejector, which is usually mounted inside the handle of the gun. As a result, the sleeve is usually ejected laterally upwards through the ejection window of the closure, while the closure continues to run back and a possibly existing hammer or a striker (also called hammer or cock) spans and thus manufactures the fire readiness.

Arrived in its rear disengaged position, pushes the closing spring (also called closing spring or feed spring) the closure back to the front. The closure introduces a new cartridge from the magazine to the cartridge chamber. In the front In the closed position, there is a new cartridge in the cartridge chamber and the hammer or the firing pin is stretched and the weapon ready to fire. For another shot, the shooter now only has to release the trigger and press again.

If the magazine is shot empty, the magazine feeder presses on the catch catch, which engages in a corresponding recess of the closure and holds the closure in the rear disengaged position. After the magazine change, the shutter catch lever, which is under relatively high pressure by the closing spring, must be unlocked by at times strong force application. With gloves on, with sweaty hands, or under enormous stress in the field, this process step can become a difficult task, which in the worst case can lead to the death of the task force in the event of failure or delay.

Currently, there are several approaches that should facilitate this powerful unlocking or try to circumvent. For example, projections on the catch lever, so-called thumb pads or textures are provided in order to increase the friction and thus prevent slipping of the finger when unlocking. The handling technique of the so-called "Double Hand Release" tries to address this problem by the thumb of the second hand of the shutter lever is actuated, as this more pressure can be exerted on the catch lever.

Another possibility is to change the handling of the weapon to unlock the lock after inserting a new magazine and to bypass the operation of the shutter catch lever, such as the so-called "Overhand Release" or the "Sling Shot", in which with the second hand the shutter is manually moved further back to the disengaged position to release the pressure on the shutter catch lever, which is returned to the release position by its return spring.

However, the previous procedures require a comprehensive training from the user in order to be "blind" in case of emergency can. This can not be assumed by a task force, which was most likely never involved in a firefight.

From the company Mauser-Werke A.-G. There are several gun models, such as Model 1914 or Model HSc, which automatically release the shutter upon insertion of a magazine so that it can move to the forward closed position. All these model variants, however, have in common that can not be distinguished between a full and an empty magazine, whereby a closed closure represents an uncertain state of charge, which is detrimental to the usual safety aspect in the handling of such firearms.

Presentation of the invention

It is therefore an object of the invention to improve a firearm to the effect that the above problem is eliminated and an automatic release of the shutter and return movement is made possible in the closed front position during insertion of a new magazine. At the same time, the solution should be as simple and inexpensive as possible to keep the production costs of the weapon low.

This object is achieved in that a trigger element for automatically releasing the shutter in the closed front position is provided exclusively when inserting a new loaded magazine, and that the trigger element in a front starting position with an attack surface in the path of movement of a control surface of the magazine in the Magazine receptacle protrudes and when inserting the magazine is engageable with this, and further that the trigger element is kinematically coupled at least for a movement portion when moving from the front starting position to a rear end position via an active surface with the closure, wherein at the end of the coupled movement section of the Closure relative to its rear disengaged position is offset by a further portion along its path of movement to the rear, whereby the shutter catch lever is released, and further that the effective surface of the trigger element in his hi nteren end position with the closure is again disengaged.

The invention allows the shutter, which is fixed after the magazine is empty in the rear position, to automatically unlock again upon insertion of a new full magazine and to restore the fire readiness. This results in a gain of time and security for the user. The conventional function of the shutter catch lever is not adversely affected. It Thus, as before, the shutter in the rear position for transfer or control of the weapon can be fixed (manually or after emptied magazine). Only when inserting a new full magazine, the shutter is released, but not when removing the old magazine or when inserting an empty magazine.

The invention can thus be realized by adding only a single component. The closure is pressed a little backwards during insertion of the magazine and thus the same movement is exercised, as in the conventional case, manually by the withdrawal of the closure with the second hand ("overhand release") must be performed.

One possible particularly simple embodiment of the invention provides that the triggering element is a displaceable plate provided with at least one control pin and arranged in the housing.

Another feature of the invention is that the scenery has a game or a corresponding alternative track section, so that when ejecting the magazine, the platelet is movable past the shutter in its initial position. As a particularly simple and thus cost-effective variant, it is an inventive feature that the backdrop is a substantially parallel to the direction of running slot.

When removing a magazine, the trigger must be moved past the shutter to return to the starting position. For a certain game in the backdrop or an alternative track section is provided. It will be understood by one of ordinary skill in the art that in both embodiments, the control surfaces and engagement surfaces and / or the link and the control pin may be disposed on the respective other component (magazine or trigger element or trigger element or housing).

In order to ensure a functional reliability of the firearm according to the invention in any position, it is according to a further feature of Invention provided that the trigger element is biased by a spring in the direction of its initial position.

According to a further feature of the invention, it is provided that the control surface of the magazine is an upper edge or a lateral projection of the magazine housing. By using already existing magazine edges and projections as a control surface, the magazines of a certain type of weapon already on the market need not be modified and can continue to be used, which increases the economic efficiency of the invention.

Finally, it is a feature of the invention that the engagement surface of the trigger element is at the same time the end stop of the magazine in the magazine holder. Depending on the type of weapon, the triggering element and the other interacting surfaces must be adjusted in such a way that the magazine locks in the moment in which the closure is also released. If the attack surface of the trigger element simultaneously forms the end stop of the magazine, this can be realized in a particularly simple manner.

Way (s) for carrying out the invention

The in the Fig. 1 and 2 The firearm shown in the prior art comprises a housing 1 in which a magazine 2 with cartridges 3 can be used. An unillustrated closure is movably disposed relative to the housing 1 at the top of the weapon and provides for the transport of the cartridges 3 to the loading chamber and the transport of the Partonenhülsen to the ejection window. The shutter is biased toward the front closed position by a shutter spring and is moved rearwardly against the force of the shutter spring by the recoil when firing the weapon. Once the last cartridge 3 is fired from the magazine 2, the shutter moves backwards and an upper edge of the Magazinzubringer 7 pushes a projection 5 on the catch lever 4 the same upwards (see Fig. 2 ). The illustrated embodiment is realized for example in a Glock® such. In other manufacturers, the shutter catch lever 4 is actuated at different locations, for example laterally on the magazine.

As a result, the shutter catch lever 4 engages in a corresponding recess of the shutter and holds it in the rear disengaged position. After changing the magazine 2, the shutter catch lever 4 must be released to bring the shutter back to the front closed position. This can be done for example by pressing down the shutter catch 4 via the actuating surface 6. Since the force of the closing spring acts on the closure and thus also on the catch catch 4, some effort is required to release the catch catch 4 via the actuating surface 6. As an alternative method, the user with the second hand, the shutter a little further pull backwards, whereby the shutter catch lever 4 is relieved and moves again by its own return spring in the release position. Both methods require force and / or exercise by the user and are difficult to accomplish in an emergency in the field.

The Fig. 3 to 5 schematically show a magazine change in a firearm according to the invention. In addition to those already in the Fig. 1 and 2 Parts described a trigger element 9 is provided, which a guided with a control pin 13 in a gate 14 platelets. The triggering element 9 has an engagement surface 10 which cooperates with a corresponding control surface 11 on the magazine 2. Fig. 3 shows the situation when inserting a new magazine 2 just before the attack surface 10 comes into contact with the control surface 11. The shutter 8 is secured in the rear disengaged position and by the shutter catch lever 4, because as soon as the magazine 2 is empty, the magazine feeder pushes the shutter catch lever 4 upwards ( Fig. 5 ).

If a magazine 2 is inserted ( 3 and 4 ), the triggering element 9 is pressed by the control surface 11 with its active surface 12 against the closure 8, whereby this is moved a little further back. As a result, the shutter catch lever 4 is relieved and can move by its return spring in its release position. Once the magazine is fully inserted ( Fig. 5 ) releases the trigger 8 the shutter 8 and this can move back to the front closed position.

When inserting an empty magazine, although the shutter 8 is released by the trigger element 9, but the shutter catch lever 4 catches the shutter 8 at the same time, since this is pushed up again by the Magazinzubringer 7. As a result, a distinction can also be automatically made by the invention between an empty and a full magazine, so that the usual practice in the aspect of the open closure when the magazine is empty is not impaired by unintentional closing of the closure.

When ejecting the magazine 2, the active surface 12 must be able to move past the closure, so that the trigger element 9 again in his starting position can return. The provision is made by a spring 15. So that the trigger element 9 does not hang on the closure 8, a game is provided in the gate 14.

The embodiment according to the FIGS. 3 to 5 In effect, it mimics the movement normally performed by the user with the second hand in retracting the shutter to release the shutter catch lever. However, this at the same time as changing the magazine, which can not be done manually.

By automating the release of the shutter catch lever, the operational readiness of the firearm can thus be restored faster, without the user consuming training or high effort required. At the same time, the safety of the usual function of the shutter catch lever is not affected.
