Abstract

Magazine safety units for use in a self-loading firearm with a removable magazine are disclosed. An example safety unit includes a swiveling lever which is held by a spring in the movement path of a bar which is connected with a trigger. The lever engages the bar in an impeding manner. Engagement of the lever with a part of the magazine swivels the lever out of engagement with the bar.

Description

The invention relates to a pistol with magazine security according to the preamble of claim 1; as known from US 5,355,768.

All location designations used in these documents Start from a self-loading pistol, which is in normal Stop, with the barrel running horizontally and the magazine is more or less obliquely from below extends upwards. The mouth points forward. The Magazine has two opposing surfaces, which end up and back in the magazine lips. In front the magazine lips, the magazine is lowered down, so that the cartridges unobstructed between the magazine lips can be pushed forward.

The front surface of the magazine is often bent, but is not fully on the contour of the floors, so that Do not scrub them if possible. It is therefore usually between the bullet and the magazine wall a certain Travel before. This is especially true for magazines with zigzag storage the cartridges.

Magazine backups have been known and have been around for a long time the superficial task of not being able to shoot when the magazine is removed from the weapon. there the most different constructions are known. For pistols of this type (about S & W Mod. 559), too when the magazine is removed, the closure withdrawn and the cock can be cocked, however not over the tension trigger. Also from US 4 031 648 a magazine backup known.

Modern pistols have a plastic grip, in which the handles are molded to the handle and not can be removed. The inner parts of the weapon are then not accessible, but it can not Parts are assembled, if to this assembly the Grips would have to be removed.

For its part, the applicant has recently had a magazine security suggested that at the bottom of the magazine shaft mounted backwards and has a finger, pressed by a spring in the magazine shaft becomes. When this finger is pushed back from the magazine is, then the mechanism of the weapon remains untouched. If the magazine is removed, then inhibits Part interacting with the pin with a relaxed cock a spring rod around which the striker is laid is, and thus prevents the movement of this spring rod and thus cocking the cock; the loading movement and thus the disassembly of the weapon - and of course the shooting.

The disadvantage, however, is the fact that the magazine is practical must be completely removed to the magazine backup to press. It is therefore not possible for the shooter made aware of the circumstance by the magazine security that the magazine is not yet fully inserted and is engaged.

In contrast, in the aforementioned US 5,355,768 a Magazine lock with a pivot lever shown around the axis of the trigger is pivotable and from the front the bar engages behind. This swivel lever is on train loaded and can be bent when the trigger strong is pressed, but the magazine is removed.

In certain cock lock constructions is with the Rod and the cock locked. Then it can be locked Rooster the sled of the pistol not withdrawn so far to retrieve a cartridge from the chamber. If the magazine with loaded gun unloading is not possible.

Now it is common in military and civilian guards, e.g. in the case of changing of the guard, first to remove the magazine, then to load the weapon, the supplied cartridge and then unload the weapon and the to pass full magazine to the changing of the guard. For weapons of the type mentioned above, this is not possible because after the removal of the magazine, the weapon can not more are loaded. It is not possible that loaded weapon without unloading a magazine.

Now you could empty the removed magazine, then the insert empty magazine into the weapon and then this discharged. In years of use but that tends Security personnel sometimes to the safety in favor of Comfort neglect something.

Starting from this problem situation, it is an object of the invention to find a more reliable magazine backup. Also, the magazine backup with a gun with Discharge prevent the movement of the rod, and with it also the movement of the trigger.

The magazine security itself can be any of these parts directly or via an intermediary, since all these parts between each other movements in the opposite direction transferred, if not an interrupt mechanism this prevents.

The invention has the further task of this source of danger defuse and seek a magazine backup, the - while preserving proven castle constructions - allows unloading of the weapon with the magazine removed, although there is a magazine backup.

To solve the problem contributes according to the invention that the Part of the magazine on which the pivot lever is applied, whose Top edge is.

The magazine does not need any additional training but the pivoting lever settles with any Training on the top of the magazine and will be so pivoted out of engagement with the rod by this, though it is introduced so far that the magazine holder holding the magazine in place.

The magazine is in turn through the magazine shaft of the Self-loading pistol led very precisely, so that even the Narrow sheet edge reliably supports the pivoting lever. Besides, the magazines are getting straight nowadays of heavy pistols, for reasons of weight reduction, made of plastic. The plastic wall but the magazine is relatively thick, so that a even better support of the pivot lever takes place.

But it is especially important that there is no magazine special training is required, so that a magazine from another series production can. This reduces the cost of the magazine security invention. But it may also be appropriate to have a counter seat to train on the magazine, but very simple can be.

Particularly important, however, is the position of the pivoting lever: this is located in the area of the magazine lips, ie in a region of the handle, which from the closure or Sled is covered. The pivot axis of the pivoting part is therefore not accessible after removal of a grip, or in other words: the handle required no removable handles. It is also located the magazine security, seen from below, so far on top of the magazine shaft, that it is very difficult becomes ineffective, the magazine backup with a tool close. So can be practically ruled out that an unauthorized person can shoot with his gun if he does does not own a suitable magazine.

As stated earlier, the magazine points up, a corner at the front and sides, in or near it the cartridge or its projectile from the inside of the Magazines not her rests on the wall. Prefers the pivoting lever sits on the magazine at this point, because he can cover the top of the magazine there, without causing a malfunction.

The pivot lever is in a recess laterally in Handle arranged next to the magazine (claim 1), so that he then, when the weapon shaken by a shot is additionally supported laterally from the magazine. Furthermore, the pivot lever is located at this point under the Rod, so that the pivoting lever when it is at its front End is pushed up through the magazine, he with the rear end pivots down and thereby the Rod releases. The bar needs only one Projection or a recess on its lower side, So at one point, the best against the ingress of dirt is protected.

The pivot pin of the pivot lever sits approximately in the Middle, so that a Eingriffsweg formed in the rod which corresponds approximately to the engagement path in the magazine. These power and road conditions have as expediently exposed.

The pivoting lever can simply be a flat sheet metal lever. But to optimize the management of the magazine is the Swivel lever at its front end bent so that a tongue is formed when inserted magazine flat against its front, the front of the magazine, set aside, towering over and there after bent back (claim 2). This will be a rich installation of the magazine at the front end of the pivot lever guaranteed, so that it is impossible that the Swivel lever is not pivoted when the magazine is inserted becomes. The reliability of the weapon is increased because the magazine lock reliable when inserted Magazine can be lifted. At the same time but can the pivot lever loading spring are reinforced, so that she interacts with the magazine in a surprising way and this pushes back when the catch of the magazine should not have interfered. It occurs accordingly not a situation that the magazine after the first Shot from the gun slips, because the rest of the magazine or the magazine holder has not held, but the Spring of the pivot lever on the one hand ensures that the Sagittarius can not mistake the state if the rest should not intervene, and on the other hand, that the Magazine is firmly pressed into his rest and this is why holds reliably, even if the forces of the massecuite occur should when the weapon falls down about.

The pivot lever sits either in a lateral groove (Claim 3) or over a projection of the housing. Between the bottom of the groove or the said projection and the rear part of the pivot lever is a leaf spring attached, the pivot lever with the rear end pushes up and into engagement with the rod when no magazine is introduced. This forms a structural simple and reliable solution. It is noted that understood by a leaf spring and a wire spring which consists of an angled wire, so a leaf spring with a round cross section of the spring leaf.

• der festgelegte Hahn eine geringe Rückwärtsbewegung des Schlittens zuläßt,
• daß der Hahn nach dieser Rückwärtsbewegung des Schlittens den Schlagbolzen nicht mehr erreichen kann und/oder der Schlagbolzen so blockiert ist, daß er nicht mehr zünden kann, und
• daß der Schwenkhebel vom Schlitten nach dessen geringer Rückwärtsbewegung aus seinem hemmenden Eingriff in die Stange dann herausgehoben wird, wenn der Hahn nicht mehr auf den Schlagbolzen schlagen und/oder dieser nicht mehr zünden kann, so daß trotz entnommenen Magazins und bei voller Sicherheit der Hahn und damit der Schlitten beweglich sind (Anspruch 4).

The further object is achieved by the subject matter of claim 4, thus the fact that in the aforementioned self-loading pistol

• the fixed tap allows a slight backward movement of the carriage,
• that the cock after this backward movement of the carriage can not reach the firing pin and / or the firing pin is blocked so that it can not ignite, and
• that the pivot lever is then lifted out of the carriage after its slight backward movement from its inhibiting engagement in the rod, when the cock no longer beat on the firing pin and / or this can no longer ignite, so that despite the magazine removed and the safety of the cock and so that the carriage are movable (claim 4).

In a so-called "Rücksprungschloß" moves to Example of the cock after reaching its foremost position, where he strikes the firing pin for firing automatically back to a middle position in which he no longer touch the firing pin. The carriage points Training on the return to the tap runs up and this tense. When the cock in the "middle" position is, so if the trigger is not pressed is, then there is a gap between the tap and the training of the sled, if this in his foremost position. This foremost Position is the firing position in which the magazine security must secure when removing the magazine.

Now moves the carriage from the firing position back, then picks up after a certain backward movement the sledge a position in which the cock under no Circumstances can beat more on the firing pin as he on the training of the sled bounces, before he Striker touched. Here now uses an inventive Set up and cancel the magazine backup, although no magazine is in the gun.

If the shutter is let forward again, the Magazine backup effective again.

Instead of a return lock or in addition to this can also be present a firing pin safety, the the firing pin locks if the shutter is not fully closed is closed, and / or an interrupt mechanism, when opening, without the carriage unlocked is, makes an ignition impossible.

According to the invention, the pivot lever and the carriage are now directly or indirectly coupled with each other so that after said backward movement of the pivot lever from Returning sled is made ineffective, and although still before the blocked cock in turn the Can block sledges. By disabling the Swivel lever but the inhibition of the rod and thus the blocking of the cock is lifted.

The gun according to the invention can now readily at unloaded magazine because then during - - and only during - the return movement of the carriage, if the gun is not capable of firing anyway, the magazine lock will be annulled. In short, before the sled arrived again in his firing position (foremost position) and the gun is capable of firing again, the Magazine backup effective again.

Preference is given to the pivot lever training, in particular a cam, formed in the case of inhibiting engagement the pivoting lever into the pole into a counter-training, in particular, a groove, which falls on the carriage trained or connected to this or connectable (Claim 5). In inhibitory intervention, so in the Sled in the front position (firing position), lies the Training in counter-training. Moves the Sledge (and thus the counter training) relative to Handle of the weapon (and thus to training), then The counter-training is training and burdened they and thus the pivot lever against the direction the spring, the pivot lever against the top edge of the magazine. The pivot lever takes so then (in no longer completely closed and open state of the Schlittens) as well as when imported Magazine. The tactile finger, which is formed on the pivot lever is to feel the magazine is, therefore, after pressed up.

This is a particularly useful training in that the one end of the pivot lever for engagement is set up in an abutment of the pole, the other End (called the tactile finger) for engaging the top edge of the magazine, and both ends on both sides the pivot axis are arranged, and that close formed the first end of the training or the cam is (claim 3). The cam is thus under the sled and dive into a groove that is formed in the overlying slide. The disassembly The pistol is, as usual, possible because not parts of carriage and handle behind each other.

a view as in Fig. 1, but with a relative to the handle components easily retracted slide.

A trigger 6 is extended upward and there has two Fulcrums on, of which the lower on a transverse axis sitting in the handle and the upper on a transverse axis sitting, which is mounted in a pole 5. Will the deduction 6 subtracted, so pressed to the right, then pivots He around the lower, fixed pivot and pulls the Rod 5 forward or to the left.

The rod 5 is forward (in the drawing to the left) extended; There is a (not shown) backup provided that the movement of the rod 5 forward or can prevent to the left.

At the rear (right) end of the rod 5 engages indirectly or directly into a tap (not shown) to to tension and remove this.

As can be seen from Fig. 2, the rod extends 5 right past a magazine shaft, which is a magazine 8 takes up.

Under the rod 5 (and hidden in Fig. 2 by the magazine 8) a pivot lever 2 is arranged and around a in the Handle fixed anchored transverse axis pivotable. Of the Swivel lever 2 has a rear end 3, with which he can occur before a level 4 in the rod 5, as well a front end 9. This front end 9 is from the Drawing plane angled out to the viewer, where a web extending transversely to the plane of the drawing is formed is, from the pivot lever 2 from approximately rectangular extends upward and at the top again approximately at right angles angled backwards.

Below the rear end 3 is a handle projection 7 educated. Between this and the back of the Swing lever 2 is a blade or leg spring 1 is inserted, the pivot lever 2 counterclockwise charged while the rear end in front of the stage 4 of the rod 5 presses.

The magazine 8 (Fig. 2) has laterally front in front of the magazine lips a contact edge 10, on the back bent portion of the front end 9 of the pivot lever can sit up. At the same time, the front ensures upwardly extending part of this front end 9, the attaches to the front wall of the magazine 8 that the Swivel lever 2 assumes a precise, defined position.

Is no magazine 8 in the self-loading pistol not shown in detail introduced, then take the parts described the position shown in Fig. 1: the rear end 3 of the pivot lever 2, by the spring 1 with this Swung up at the end of 3, falls before level 4 the rod 5 a.

Now, if the trigger is pressed, nothing happens and the trigger 6 can not be moved.

If the shooter overlooks that no magazine in the gun and wants to shoot, then he must Attempt to go to pressure point or the trigger to the Pull point to determine that the trigger can not move. The shooter can thus not only the Automatically secure the weapon by removing the magazine, but he also adjusts while trying to use the gun properly to use, immediately realizes that the magazine is missing.

If the magazine 8 is inserted (FIG. 2), then it engages it with the edge 10, the front end 9 of the rocker arm second and pivots it so that the rear end 3 of the Swing lever 2 dives in front of the projection 4 of the rod 5 and releases them. The weapon can now be as usual to be used. This position of the pivot lever 2 is shown in Fig. 3.

In this situation simultaneously exerts the spring 1 on the Swing lever 2 a considerable force on the magazine, which seeks to push the magazine out of the gun. Should not the magazine 8 when inserting into the gun locked properly, this is doubtless and instantaneous recognizable.

The leg spring 1 is always flat on the projection 7 on; even if this should be made of plastic is the surface pressure occurring low, so that the plastic This also reliably withstands in the long run.

In Fig. 4, a carriage body 10 is shown. Attachment parts, like the extractor's claw, the rear sight or the like omitted for simplicity. The weft direction in the drawing is to the right (right is "front").

Below the carriage is an elongated control section 20 is shown. This extends parallel to Lengthwise of the carriage, but is usually a part of the carriage, so a longitudinal web of the carriage, which protrudes downwards. This longitudinal ridge points to the Bottom of a cam 12, with a groove 14. The aforementioned longitudinal web or the said control part 20 or the cam 12 must go so far forward, that at fully retracted carriage at the Place where the groove is in Fig. 4, nor the Edge of the cam 12 is present.

The (not shown) handle on which the carriage 10th has a tap and a trigger (both Not shown). Between these parts extends the Rod (sear) 5. If the trigger is pulled off, then moved the rod 5 is forward and gives with its rear Part the cock free.

In a step 4 of the rod 5 engages from the front Swivel lever 2 with its rear end 3 a, which is a Pivot axis 18 is pivotally mounted. The front End 9 of this pivoting lever 2 carries a (in Fig. 5 better visible) tactile finger, which engages the top edge a magazine is set up. Will the magazine (not shown) pushed from below against the carriage 10, then it engages under said finger and finger raises with this the front end 9 of the pivot lever. 2 at. The rear end 3 lowers and gives the step 4 of the rod 5 free. The rod 5 can now in move freely forward and backward in their longitudinal direction. When the magazine is removed, the front end 9 dives Swing lever 2 off, and its rear end 3 engages the level 4. The pistol is now secured. These Position is shown in Fig. 4.

The pivot lever has at its rear, upper side a cam 16 which engages in the groove 14, when the carriage 10 is in its forwardmost position.

Will now, with removed magazine, the carriage 10 a pulled a little to the rear, then enters the slide 10th in a first position, in which due to the structure the lock parts, not shown here a firing a Cartridge would no longer be possible, even if the magazine backup would be missing. The cams can a recoil lock of the type mentioned or a commercially available one Lock design of the applicant. These first position is just before a second position, in the sledge through the severed tap at the load would be hindered. After leaving the first, but before reaching the second position, the groove must be 14 now have the cam 16 pressed down into a position which corresponds to the situation with inserted magazine. Now is the rod 5 is released, and the weapon can continue be loaded as usual. In Fig. 5, the mechanism the gun shortly after passing through the said shown second position.
