Abstract

The invention relates to an automatic pistol (1) comprising a hammer (5) which is connected to a spring guide pin (7) which when the hammer is cocked (5) plunges into a detachable insert (11) which supports a mainspring (9). In the insert a locking element (17) is arranged which can preferably be released and is designed to prevent the spring guide pin from plunging into the insert. The insert (11) can be replaced with a conventional insert and receive a lock (17) or magazine safety mechanism or can be configured as an irremovable locking element.

Description

Automatic pistol {AUTOMATIC PISTOL}

Rotary revolvers are known (US Pat. No. 2,945,316 and Bock-Weigel, 1989, Handbook of Small Arms, page 139), which revolves around this problem. In this rotary revolver, a keyed lock is inserted into the bottom stem of the pistol stock so that the rod (guide rod for ball spring) connected to the tumbler is blocked when the tumbler is not pulled. The tumbler may no longer be pulled. The pistol is no longer fired.

Such known rotary pistols are not reliably guarded against theft, but are guarded against unauthorized use. The (very small) key for this lock can be worn by a chain around the neck which is inaccessible to the owner of the weapon, for example an unauthorized person.

However, the lock can be opened or ruined very easily. Due to these limited design dimensions and the required toughness (recoil during firing should not adversely affect the function of the lock), the key is not designed to open the tumbler but is a screwdriver for rotating the lock. This lock can thus be rotated and opened by a suitable tool even when there is no key. In addition, the handle claws can be removed such that they can be lifted from the side and lifted or otherwise not used. Finally, when the handle hinge is removed, the spring guide rod blocked by the lock may simply be clipped off. For this reason, an obstacle may occur while pulling the rotary revolver, but it may be fired without difficulty when the first retraction is pulled.

Since the lock is applied to the floor which can be clearly seen in the pistol stock, it can be immediately seen even in poor inspection, and the lock can be disabled in the manner described above in order to be able to use the weapon if necessary.

The closing cylinder is disclosed in the general German patent 39 37 042, which is placed in an accessible magazine from the bottom and controls the slide to engage the insert and prevent the movement of the rod. The reduction in magazine capacity is a particular drawback.

Another drawback of the known lock is that the component rotated by the key has an axis of rotation that traverses the firing direction. Thus, the moment of inertia generated during firing is applied roughly to these components in a tangential direction, causing them to rotate if they are not balanced. If such locks are slightly worn out over long periods of use or frequent operation, there is a risk that the locks will automatically lock after the launch is made. For this reason, other uses of this weapon are suddenly and unexpectedly impossible until the lock is released again.

The closed cylinder of German Patent No. 39 37 042 for young children and untrained persons discloses an almost insurmountable obstacle. Also, the mounting of such lock near the tumbler makes the movement of the spring guide rod impossible. Reliable attachment of the lock in the frame has at least no basic difficulty. However, the pistol stock must be redesigned. The necessary modifications to safety locks and weapons are very expensive.

The shortcomings just described are still not completely resolved, and the person who wants to take his hand to the weapon stored by Locke can see once and how the weapon has been secured. He opens one more to this safety device by roughly drilling the closing cylinder to release the lock.

Known proposals for placing measurement sensors and electronics in the pistol such that they are only used when a specific hand contour pattern is recognized are not feasible. If an authorized user is wearing gloves or is bandaging, and if his hands are very dirty, the authorized user may become unusable.

Another safety device is a so-called magazine safety device; This magazine safety device prevents the use of weapons when the magazine is removed. Civilians remove magazines when they remove their pistols, but they no longer care about cartridges in the barrel. Ammunition safety devices prevent accidents during handling of likely unloaded pistols.

Known magazine safety devices are mostly associated with triggers and advance mechanisms. They have a filler that extends into the magazine shaft, which actuates the obstruction when it is not pressed backward by the inserted magazine. This magazine safety device increases the complexity of the required device, thereby inevitably reducing the reliability.

Summary of the Invention

It is an object of the present invention to modify the aforementioned automatic pistol to eliminate at least some of the above mentioned disadvantages of the prior art.

In particular, the present invention provides a method for implementing by improving one of the safety device embodiments in the existing design of the automatic pistol of the type mentioned above in a simple manner.

The method should preferably be implemented in a simple, robust and reliable way.

This is solved by claim 1 of the present invention, i.e., the aforementioned general pistol has a protrusion that obstructs the movement of the rod, which is combined with the insert.

The rotary revolver with the lock described above also has a device for blocking the rod. However, the device is integrated in a self-reinforced frame and position normally reserved for magazines in automatic pistols.

On the other hand, in the present invention, the protrusion for blocking the rod is engaged with the insert as used in a conventional automatic pistol previously known. During assembly of the pistol it is necessary to engage the insert according to the invention instead of the previous insert to form the pistol, which is different from the usual one (if the protrusion is combined with the notch of the rod). Can selectively prevent advancement.

The insert may have a releasable detent (claim 2). However, the detents can be designed permanently and non-manufacturably so that tumble pulls or advances are prevented. Such a detent can be mounted and removed by a wrench tool as needed. In the last case, the automatic pistol according to the invention is provided with a lockable lock.

The detents placed in or formed by the inserts can be comparatively non-formal (claim 3), making the automatic pistol unusable by replacing existing known inserts with detent inserts according to the invention. These possibilities include gun shops that store weapons in showcases; Similarly, police stations or military units for storing stockpiles; Important for transport of weapons, etc .: If a shop thief has a pistol with a detent insert in the show window, or if he wants to steal a weapon from the inspection and run away with it, load the weapon with transported ammunition. There is no danger of his escape. At police stations or in the military, individuals responsible for the protection of weapons may not acquire weapons for private use of the weapons. Similarly, a transport company employee cannot misuse a weapon along the way to practice shooting. None of this is done because the weapon is properly assembled but not fired. Of course, inserts that operate weapons while locked must be stored away from the pistol being stored. No matter how he looks, replacing the insert and arming of the pistol is a trivial matter.

The detent is preferably designed as a lock from a broader perspective. To achieve this object, the back of the rod is coupled at the end of the lock or with the protrusion of the rod; Or a lock that engages the wrench tool. Closed cylinders are generally not provided because these closed cylinders are too sensitive to the high loads to which they are exposed (claim 4).

However, in order to limit abuse, the present invention has a very different and therefore very unique path in the weapon that hides the lock from the point of view of an unauthorized person so that the lock is invisible so that the weapon is protected from unauthorized use. The engagement protrusion of the lock to which the key must be inserted for operation is preferably configured so that unknown and unauthorized users are not aware of the presence of the detent (claim 5). The pistol will not work except in the case of its intended use. However, there are many reasons for this. In some cases, the lock cannot be manipulated because it does not know the lock. The above solution with a replaceable insert which prevents firing suggests the same advantages.

Applicants will appreciate that the claims are expressly claimed for separation protection for the application of hidden detents, and for hunting weapons, sports weapons and various military weapons as well as automatic pistols. The detents need not only operate on the rod, but also on other elements, and the fixation or movement is suitable to prevent the use of weapons.

The resulting deformation of the hidden application of the lock or detent can achieve independent protection.

Thus, for example, a lateral progression threading hole can be provided in a sports weapon having a cylinder closure in the frame, and the Allen screw 6 which can be rotated by an Allen wrench has a slightly open closure. Placed in the recess. In the tightly tightened state, the screw is placed deep in the hole and cannot be recognized from the outside without difficulty. The screw then penetrates into the counterprojection to protect the closure. When the screw is released by the wrench, the screw is visible from the outside and the closure is released so that the weapon can be used.

A modification of the invention is made by providing a cover for making the lock invisible (claim 6). In the case described above, the cover can be a screw with a short shaft, which is screwed into the hole in front of the stud screw.

An unauthorized user who realizes usability by acquiring an automatic pistol according to the present invention and checking the magazine will find that he cannot use it when he wants to fire this weapon.

Even if an unauthorized user tested the weapon to use the weapon and knew that the weapon did not work, he would disassemble the weapon, thinking that the weapon was defective. In general, however, this is not possible, since the detents are held together with the detents which are not pulled and the detents are fixed and the removal of the slides is prevented. In no case operation is caused on the lock because he does not know that such a lock exists. The presence of such locks is at best known to specialists in gun dealers or those skilled in the field of small arms.

It is therefore excluded that this weapon may be used immediately by an unauthorized individual or immediately after theft. Simple, small and sturdy locks can be used, which are more cost effective than expensive safety locks. If a young child or youth steals the weapon, after discovering the flaw of the weapon, a limited group of people generally associated with it believe that the weapon can be returned before the accident occurs.

In the simplest case, a lock may be placed on the rotary revolver described above, but some recess may be formed therein to allow access through a hole that may be closed by a plastic plug. This plastic plug is suitable in color and design for the part surrounding it, and cannot be recognized as a removable part. For release or blocking, the plug must be removed by the nail to provide access to the key. While purchasing a weapon, several plugs may be provided from the outset so that in case of damage or loss, a replacement can still be obtained. However, the problem of possible effects of inertial forces on locks is still not solved. When the lock is not balanced and the axis of the lock extends across the reaction direction, the inertial force can act on the lock to change the position of the lock.

The present invention thus constitutes a tilting of the lock by 90 ° in a preferred embodiment such that the rotational axis of the lock is parallel to the firing direction of the lock weapon (claim 7). The inertial forces that occur as a result of firing and aligned parallel to the firing direction act on the rotatable parts of the lock in the axial direction and cannot rotate these parts. Instead, these parts are axially pressed into their mounts and thus are firmly fixed while inertial forces are exerted.

In this case, the key can be inserted from the back side of the pistol stock after the cover provided on the back side of the pistol stock is removed.

However, the present invention proposes in the preferred embodiment (claim 8) that the magazine is designed as a cover, ie an engaging projection provided for use of the key is configured on the back side of the magazine shaft. It is generally believed that the bottom of the magazine lies above the front side of the magazine bottom. When the lock is disposed at the bottom end of the magazine shaft on the rear side of the magazine shaft, the straight key can comfortably reach the lock when the key is pressed along the lower front edge of the magazine shaft. It is preferable to use the aforementioned front edge as a support to reliably insert the key into the protrusion of the lock.

These protrusions then become unpolluted and invisible as in the case of different covers.

It was pointed out that magazine shafts in automatic pistols are limited to the rear only by guides, not by closed walls. The insert forms a guide on one end and the wall forms a magazine shaft. The insert is thus freely accessible from the magazine shaft but poorly recognizable.

However, the insert may form a magazine safety device (claim 9); The filler pressed into the empty magazine shaft by the spring actuates the detent in the insert; When the magazine is inserted, the filler is pressed by the magazine and pushed in and releases the detent. In this way, the weapon is blocked from firing as soon as the magazine is removed. Weapons cannot be fired.

The external dimensions of the different inserts (previous inserts without additional functions, inserts with permanent detents, inserts with releasable detents or locks, inserts with magazine safety devices) are the same. All other related features related to the present invention (length of spring guide rod, design and length of ball spring, hole in rear wall of magazine shaft) (with or without lock, permanent detent, magazine safety device) As it is preferably the same design in all types of pistols, an insert with a lock or the like can ultimately be provided later as an improvement component for an existing pistol (still without the variant according to the invention).

Also a kit consisting of a pistol and at least two different inserts is an article of the invention (claim 11).

The rod is then preferably intended for the wound ball as a spring guide rod for the spring. However, another ball can hinge the tumbler with a separate rod in the spring, the purpose of which is to engage the lock.

The pistol stock itself is preferably designed as a single part together with handle hinges of reinforced or unreinforced plastics (claim 10). Thus, it is not possible to remove the handle claws and act on a recognizable lock.

The object of the present invention is further described with reference to the accompanying schematic drawings.

The invention is preferably attached to a movable rod with a tumbler movable by a returning slide, a removable magazine, a tether extending down within the pistol stock, and a An automatic pistol having a hole or recess and an insert into which the free end of the rod is inserted into the hole while the rod is moving.

Automatic pistols of this type are manufactured by the applicant, but are already known with these features since the beginning of the century (eg Colt Model 1911).

The insert is in principle already known in Browning Model 1903, and the ball on the back side of the pistol stock, in which the components forming the blind shaft are individually machined and assembled, allows the pin to accommodate the pin. This is because the blind shaft cannot be formed by broaching or the like to accommodate. This problem no longer exists in many modern automatic pistols, since the pistol stock is mass produced in one piece of plastic by injection molding. However, the insert is generally retained because the insert forms a stop for the spring, which insert can assemble an improved inorganic mechanism without the ball being loaded by the spring during assembly. This insert is then joined, on which the ball is spring-loaded, thereby applying tension.

Simple designs have already been conceived in military weapons for reliability. However, private consumers often require a wider range of safety features. Thus, apart from mass production of military weapons, it is necessary to design for civilian use, which naturally leads to an increase in manufacturing costs. However, additional safety is often required by the consumer for military weapons as a result. Thus, previous efforts have been made to obtain safety devices that allow simple installation and improvement of weapons that do not have such safety.

One such safety is the safety against unauthorized use.

Small weapons for game protection, self-defense, etc. should, in principle, not be loaded when they are not transported and when they are not reliably protected against unauthorized use. However, the habits for many years are contingency, so loaded weapons are only placed in weapon cabinets, which are often improperly guarded. Therefore, it is common to remove the magazine from the automatic pistol and place it next to the weapon. However, often loaded weapons are safely placed in, for example, drawers or shelves.

Therefore, it cannot be excluded that a weapon ready to be used is in the hands of a person without permission to use it. Those without this permission can be young children who can threaten themselves and others with this weapon; It may also be a home invasion robber that may use the weapon during or after a home invasion.

Once someone knows where to store a weapon, a house employee can also steal the weapon and commit a crime.

People are often convinced that the ammunition is contained simply by removing the magazine. If that is the case, the weapon is removed or transported for actual use without other inspection.

Like reference numerals in the drawings denote like elements.

1 is a longitudinal cross-sectional view of an automatic pistol 1 manufactured by the applicant. The pistol 1 generally has a magazine 3, which is inserted into a magazine shaft formed in the pistol stock 13.

The tumbler 5 is mounted to pivot in the pistol stock 13, where the rod 7 runs down, the rod 7 being loaded by a spring 9, which spring It is designed as a wound spiral spring, on which the rod is pushed, the upper end of the spring is supported on the wide part of the upper side of the rod, and the lower end of the spring is supported on the insert 11. The lower end of the rod 7 is designed to be square and placed in a square blind hole 19 (FIGS. 3, 4, 5, 7 and 8), the hole 19 being in the insert 11. Extends downward and the top is open;

The lock 17 is formed in the insert 11 and the insert 11 is described in more detail below. The lock 17 can have two positions, a blocking position for blocking the square hole 19 and a release position for releasing the square hole 19.

1 shows a tumbler 5 in an unpulled position; The rod 7 is then the ball pushed upward by the spring 9; The lower end of the rod slightly penetrates into the square hole 19 (see FIG. 2). If the tumbler 5 is pulled, i.e., pivoted about 60 ° clockwise in the figure of FIG. 1, the tumbler 5 forces the ball to push the rod 7 downward in the opposite direction to the force of the spring 9 Thus, the square end of the rod 7 penetrates further downward in the square hole 19. When the lock 17 is in the locked position with the unpulled tumbler 5, the lock blocks the square hole 19 so that the rod 7 does not move downward, which causes the rod to engage the lock 17. This is because its square end stops. As a result, the debating machine 5 is blocked in the position shown in Fig. 1 and then blocks the slide of the pistol 1 (without reference sign), so that the pistol 1 can neither be pulled nor released. have.

On the other hand, if the lock 17 is in the unlocked position, the lock releases the square hole 19 when the tumbler 5 is pulled and the square end of the rod 7 can be inserted into the square hole 19 without obstruction. Can be. The pistol is then ready for use.

Under the end of the square blind hole 19, the insert 11 has a transverse hole 29 that can be adjacent to be aligned with a transverse hole of the same diameter in the pistol stock 13. The pin 15 penetrates through both transverse holes to make a transition fit or a slight press fit into the transverse holes of the pistol stock 13. However, the portion of the pin 15 penetrating the insert 11 is deflected with respect to its end and has a smaller diameter.

During assembly, the insert 11 is pushed into the barrel stock 13 in a direction opposite to the force of the spring 9 until the two transverse holes described above are correctly aligned. The pin 15 is pushed into it. Lose. If the insert 11 is released, the ball 9 acts on the insert 9 and lowers the insert until the wall of the transverse hole 29 lies on the cross section of the pin 15 having a smaller diameter. And to the outside. While again pressing the pin 15 outwards, the pin has a recess between the large diameter and the small diameter and reaches a rest position at the side of the insert 11 on the edge of the transverse hole 29 belonging to the insert. Thus, when the insert 11 is pressed into the pistol stock 13 against the force of the spring 9, the pin 15 can again be pushed outwards until the transverse holes are correctly aligned.

Thus removal and engagement of the insert 11 can be carried out easily and quickly only when it knows how it is done; It is not possible to simply disable the pin 15 without at least causing serious damage.

The insert 11 has guide pieces 21 on both sides (Figs. 4 and 6), which guide pieces 21 are pressed into complementary grooves in the pistol stock 13 and with the pin 15 Secure (11). The front surface 25 of the insert 11 forms a back wall on the lower end of the magazine shaft. The lower end of the insert 11 is designed as a stub or belt eyelet 23.

Pistol stock 13 is made of a single piece of plastic that is high load resistant and impact resistant; Inserts are also made of such materials.

Apart from the lock 17, the above detailed description of the pistol 1 and the insert 11 corresponds to the prior art.

In a first variant, the insert 11 is described in detail with reference to FIGS. 3 to 14.

The insert 11 has a receiving hole 27; This receiving hole 27 receives the lock 17 and is laterally displaced with respect to the square hole 19 (FIGS. 6 and 8) and a neck 31 narrowed towards the front surface 25. To form; The neck 31 and the receiving hole 27 are coaxial and both are cylindrical. The snap-in hole 33 is parallel to the transverse hole 29, has a diameter that is clearly smaller than the transverse hole 29, and is biased to one side near the neck 31. ) (FIG. 8).

The lock 17 is also formed by a cylindrical snap-in block 35, which has a smaller diameter neck piece 37 which is coaxial and cylindrical. The snap-in block 35 is rotationally fitted in the receiving hole 27 and the neck piece 37 fits in the neck 31, where the end piece having the front surface 25 of the insert 11 ( The radial end surface of the snap-in block 35 with the radial end surface of 37 and the rear surface of the insert 11 is closed horizontally.

The snap-in block 35 has a radial recess 41 adjacent the neck piece 37, which recess 41 is bounded by two rectangular surfaces of the snap-in block 35 (FIG. 10). This rectangular surface lies behind the square hole 19 after engagement of the snap-in block 35 and the insert 11, the axis of which is perpendicular to the axis of the snap-in block 35.

The spring pin 43 passes through the snap-in hole 33, which spring pin 43 is placed under some pretension with respect to either of the rectangular surfaces. When the snap-in block 35 is rotated, the vertex between the two rectangular surfaces extends above the spring pin 43 in the longitudinal direction of the spring pin 43, which spring bends elastically, which spring Pin 43 is reinserted into one of the rectangular surfaces to form a bistable lock.

In one locking position of the snap-in block 35, the peripheral surface of the snap-in block 35 opposite the recess 41 (position in FIG. 7) closes the square hole 19, thereby providing a rod ( 7) cannot be inserted into the square hole 19. In another locking position (FIG. 8), the square hole 19 is released. FIG. 8 is a cross-sectional view taken along line VII-VII of FIG. 7, but the lock 17 is in the locked position in FIG. 7, but in the unlocked position in FIG. 8.

The free radial surface of the neck piece 37 has two engaging blind holes 45 facing each other with equal radial spacing, with counterpieces on the ends of the tool (FIG. 14) engaged in the holes. Can be.

If the magazine 3 is removed from the pistol 1 shown in FIG. 1, the extension of the axis of rotation of the snap-in block 35 and the neck piece 37 passes under the extensions of the front and bottom edges of the magazine shaft. do. When the tool shown in FIG. 14 is inserted into the engagement hole 45 of the lock 17 and the neck piece 37 together with the engagement pin, the central axis of the tool is with the snap-in block 35 and the neck piece 37. Extending coaxially, the tool is placed and guided against the front lower edge of the pistol stock 13. By rotating the tool, the snap-in block is switched between its two locking positions, ie the lock 17 is switched between its blocking position and its release position. The spring pin 43 ensures proper retention of the block so that the lock cannot escape the release position by the shaking of the weapon during firing. The overlap of the lock components can be seen from the development of FIG. 13.

15 shows another variant of the insert, which is indicated by reference numeral 47. The insert 47 has only very short blind holes 53 (instead of the square holes 19). If the insert 47 is joined in place of a conventional insert, the rod 7 is placed at the lower end in the short blind hole 53, which blind hole centers the rod 7 but does not move downward. Do not allow it. The insert 47 thus prevents the use of the weapon 1 by preventing the tumbler 5 from being pulled out. This insert is inserted during storage, shipping or display of the pistol 1. If the pistols are sold, paid to soldiers or police officers or obtained by other recipients, insert 47 is removed in the manner described above and replaced with a conventional insert.

FIG. 16 illustrates another embodiment of an insert, which is indicated by reference numeral 49. The insert 49 has a filler 51, which is pressed into the magazine shaft by a spring (not shown). If the magazine 3 is inserted into the magazine shaft, the magazine is placed against the front surface 25 and then presses the filler 51 in the direction of the arrow into the insert 49.

For example, the pillar 51 intersects the square hole 19 and has a notch; If the pillar 51 is pressed into [the magazine 3 of the magazine shaft], the notch coincides with the hole 19 and the rod 7 can be inserted into the hole. If the pillar 51 is in the marked (removed) position, the magazine is removed and the shaft of the pillar 51 intersects the aperture 19 to prevent movement of the rod 7.

The rod 7 then has a notch through which the shaft of the pillar 51 can pass in a blocking manner when the tweezers are pulled and the rod 7 is in its lowest position. The pistol 1 can thus be secured even when the tumbler is pulled and the magazine 3 is removed, since the fixed rod 7 does not allow the ball to transfer the force of the spring 9. ) Is not priced. However, although the pulled catch holding hammer 5 can be released, the catch 5 becomes a safety catch when the magazine 3 is inserted.
