DE19629978A1 - Cable-less laser pistol for firearms training - Google Patents

Abstract

The pistol simulates the effects of firing using a built-in laser which is supplied with power by a mains-independent accumulator (25) built into the pistol grip. The circuit between the laser and the accumulator contains microswitches which open and close the circuit during firing and activate the laser. The trigger device enables continuous firing using the same operating procedure as for a real self-loading pistol, whereby the same trigger characteristics are produced.

Description

The invention relates to laser guns according to the preamble of claim 1.

In the shooting training of weapon carriers, for. B. by police officers, instead of using sharp loaded pistols with laser pistols, which are not used for shooting, son which simulates a sharp shot. Conventional laser guns different Design allow a realistic or even realistic shooting training not because they can only fire a single simulated shot, for another shot, however, actuate the cocking handle again (for a P7 pistol) or the firing lever (for other types of pistols) has to be cocked again. There with repeated shots in a continuous shot sequence without renewed Operation of the clamping handle or renewed tensioning of the impact lever was not released be, so that the shooting training takes place under conditions that from the knitting deviate significantly. Furthermore, a Ka is in the known laser guns Bel connection between laser and power grid required, d. that is, the trainee such a training pistol can not use anywhere and the cable in the end often feels disturbing or obstructive when practicing.

The object of the invention is to propose a laser gun for shooting training, the practical one as far as possible under practice conditions corresponds to the set, which can be operated in a location-independent and wireless manner, and several shots immediately with the pistol used in practice one after the other without pressing the clamping handle again or re-tensioning the Stroke can be "delivered" d. H. the delivery can be simulated.

According to the invention, this object is achieved with the features of the characteristics of the An Proverb 1 solved. Further embodiments of the invention are the subject of the Unteran claims.  

In the case of a pistol that is operated with live ammunition, it accelerates through the Conversion of the propellant charge from the solid gas to the gaseous state push the bullet through the pipe. For a P7 pistol (as used as a service weapon is used by the police, and as described below in the description of the invention is used), is immediately after the separation of the projectile and sleeve Part of the powder gases are passed through the bore into the gas cylinder. The one in the gas cylinder The resulting gas pressure delays the backward movement of the joint via the piston closure. After the gas pressure in the pipe has dropped, the piston slides with it the lock backwards to the rear reverse position; thereby the lock the excited.

At the beginning of the lock return, the interrupter lever is removed from the control cam of the lock pressed down against the trigger bar. This trigger rod will pivoted about its pivot point and releases the front arm of the transfer lever; this breaks the connection between the trigger and the transmission lever. The rear arm of the transfer lever swivels under the pressure of the form spring above and lies down in front of the flag of the firing pin. At the same time, the fallsi moves upwards and locks the firing pin.

The extractor takes the cartridge case with it, which is pulled out of the cartridge chamber. In the further closure return, the sleeve is guided against the closure catch lever and ejected shortly before reaching the rear locking position. Now the next one ste cartridge inserted under the pressure of the feed spring into the sealing track. The Tensioned closing spring drives the lock forward, the push floor pushes edged the cartridge out of the magazine and inserted it into the cartridge chamber. In the last Section of the breech forward, the firing pin from the ge up pivoted transmission lever gripped and cocked again. As long as clamping handle and Ab the shooter is still depressed, the interruption remains between transfer lever and trigger lever exist. Only when the breech is back in front Has reached position and the shooter releases the trigger, trigger and Un  Breaker lever pivoted into its starting position. The breaker lever engages its reinforced part into the semicircular cut of the closure. The deduction bel comes with its approach to lie behind the front arm of the transmission lever. The interruption is canceled and the pistol is ready to fire again. The An set on the trigger pulls the transmission lever on its when you pull the trigger Nose up front.

In contrast to pistols, those with live ammunition are used for laser pistols shooting is done without ammunition and only one shot can be fired simulated will. Another shot is not possible because the gas pressure / back pressure of the ignited cartridge and thus the functions of the breech-back and pre-run for the preparation of the new readiness for fire are omitted. With previously known Laser guns must therefore be fired in order to simulate multiple shots in a row can be released, the cocking handle released and for each subsequent shot the cocking handle operated again or the firing lever is cocked for other pistol brands.

With the laser gun according to the invention, these problems are eliminated and it becomes a realistic or realistic shooting training, also under Ab multiple shots and thus simulate under real operating conditions Conditions.

To do this, it is necessary to turn self-loading pistols into laser pistols using the following measures retrofit or these retrofits in the manufacture of laser guns view:

• 1. A special laser is installed in the tube or in the barrel of self-loading pistols,
• 2. the laser is operated by batteries, the battery preferably being a plug-in, replaceable battery is designed in the form of a dummy dummy, so that a ka bellless pistol is achieved
• 3. When loading or cocking the gun, the laser is switched on via a microswitch Current laid,  
• 4. via a further microswitch, the laser is activated when the shot is triggered fourth, the microswitch being operated by a trigger blade with grub screw becomes,
• 5. the trigger device is modified in such a way that a constant firing is possible with the same handling as with a self-loading pistol, d. H. the existence permanent deduction or a permanent shot at the same deduction values, namely preferred path, preferred weight, pressure point, trigger weight, trigger diameter case, is ensured.

The necessary to convert from a self-loading pistol to a laser pistol Conversion measures are extremely simple, inexpensive in the solution according to the invention stig and exceptionally effective. These changes are as follows:

• a) A special laser is installed in the barrel or barrel of the gun. That laser is according to a special embodiment of the invention in the rear with egg A rubber ring is fixed in the pipe or barrel and in the front area by means of a thread grub screws held in the tube wall so that the laser on the visor of the Pi stole can be aligned.
• b) The laser is powered by one (or more) accumulator. The battery mulator is a plug-in, replaceable battery in the form of a dummy dummy formed, which instead of a cartridge magazine in the magazine slot of the pistol is stuck.
• c) A microswitch is used to switch the current through the laser The gun is cocked or loaded.
• d) Via a further microswitch, the laser is activated when the shot is triggered fourth; this microswitch is located behind the trigger. So the activation tion of the laser exactly at the moment the shot is triggered in the trigger device, d. H. when overcoming the pressure point / trigger weight is in the trigger tongue ei  ne grub screw provided that acts on the microswitch. This grub screw can be screwed in or screwed out further for this purpose. The switching path of the microswitch is extremely small and the trigger tongue becomes Triggering the shot moved further back (trigger diarrhea). Therefore the Microswitch in its own housing, movable in the direction of pressure under spring pressure stored against the direction of actuation.
• e) The trigger device is changed in such a way that a constant firing at same handling as with a self-loading pistol is possible, d. that is, so many Shots can be fired one after the other as in the cartridges magazine they are. When the pistol is fully loaded and cocked, the trigger is made for each one A shot was pressed and then released. The so-called Unterbre function that is missing in the trigger device for laser guns because the back pressure / Gas pressure from a fired cartridge is missing, is via a control pin and the Abän reached the trigger lever or the trigger rod, by a sub break between trigger lever and transmission lever or catch pawl and ent speaking lever arrangements, depending on the gun type. For example, the gun P7 the trigger lever through the control pin when pulling the trigger forward pivoted and releases the transmission lever. It becomes a V-shaped depression (at an angle of 130 °) in which the trigger lever slides on the control pin. The transmission lever is returned to its rest position by a special spring pivots. When the trigger is released, the trigger pulls down with its attachment again behind the nose on the transmission lever. The control pin is in one Hole fixed. The trigger is operated by the trigger spring Pressed pressure against the control pin and slides with the V-shaped recess on the control pin. The control pin is below the transmission lever and has no contact with this.

With the proposal according to the invention, a conventional pistol P7 for the Use appropriate laser gun in a particularly simple and convenient manner enough. Handling and trigger characteristics are not compared to the P7 pistol  changes. For the conversion of the fume cupboard, the new ones are limited Parts on a control pin, a special spring and an additional spring. The additional spring is stored in their pivot point by a roll pin on the handle. The short leg the spring is supported on the handle, the long leg presses against the clamping lever, who sits under the grip. Tension lever and tension handle are both together does. Only minor modifications to the P7 pistol are required, namely that Remove the flag on the firing pin and modify the trigger bar. By the flag on the firing pin is the firing pin ge by the transmission lever tense. In particular, there is no interference with the essential parts of the existing pistol, and are no complex milling and turning work or no heat treatment of the Steel parts necessary. The conversion can be carried out in a short time the.

For a better understanding of the invention, a pistol 1 of the type P7, as is used in the police service, is shown schematically in FIGS. 1, 2 and 3. The function of such a gun, insofar as it is of interest in connection with the laser gun according to the invention, is described below.

The gun barrel 2 has a forward and backward closure 3 . By implementing the propellant charge from the solid to the gaseous state, a gas pressure is created which accelerates the projectile through barrel 2 . As soon as the projectile and the sleeve have separated, part of the resulting powder gases is passed through a hole in the gas cylinder 11 . The gas pressure arising in the gas cylinder 11 delays the backward movement of the articulated closure 3 via the brake piston ben 12 . If the gas pressure drops in the barrel 2 , the brake piston 12 slides backwards with the closure 3 into the rear reverse position and the closing spring 13 is tensioned.

At the beginning of the closure recoil of the interrupter lever 6 is pressed by the cam of the shutter 3 downwards against the trigger bar 5 which is pivoted about its pivot point and releases the front arm of the transmission lever. 7 So that the connection between the trigger 4 and the transmission lever 7 is interrupted. Under the pressure of spring 8 form the rear arm swings the transmission lever 7 upwards and lies in front of the lug of the striker 10th At the same time, a fall arrester (not shown) moves upward and locks the firing pin 10 . An extractor takes the cartridge case with it. In the further closure return, the sleeve is guided against a closure catch lever and ejected shortly before reaching the rear closure position. The next cartridge is inserted into the sealing web under the pressure of a feed spring. The tensioned closing spring 13 drives the breech 3 forward, the cartridge is pressed out of the magazine and inserted into the cartridge chamber.

In the last part of the breech advance, the firing pin 10 is gripped by the upwardly pivoted transmission lever 7 and tensioned again. As long as the clamping handle 9 and trigger 4 are pressed in by the shooter, the interruption between the transmission lever 9 and trigger rod 5 remains. Only when the plug 3 returns to its foremost position and the shooter releases the trigger 4, the trigger will rod 5 and the circuit breaker lever 6 pivoted to its initial position and the Un terbrecherhebel 6 engages in a cutout of the shutter 3 with its reinforced part. The trigger rod 5 comes with its approach to lie behind the front arm of the transmission lever 7 . The interruption is now canceled and the pistol is ready to fire again.

To convert such a self-loading pistol into a laser pistol for practice shooting and the shooting training with a laser pistol largely to the conditions of the Shooting with self-loading pistol to adapt and simulate with the invention proposed the following changes:

• a) Special lasers are installed in the barrel of the gun ( Fig. 10, Fig. 11),
• b) the laser is powered by a rechargeable battery ( FIG. 13),
• c) the laser is switched via a microswitch when the gun is loaded or cocked ( FIG. 14),
• d) the laser is activated via a microswitch when the shot is triggered ( FIGS. 14, 15 and 16),
• e) the trigger device is designed so that a constant firing with the same handling as with a self-loading pistol is achieved, ie a continuous trigger is achieved with the same trigger values ( Fig. 4, 5, 6, 7, 8, 9, 17- 20).

Regarding a): As shown in FIGS. 10 and 11, a laser 21 , in a preferred embodiment with a housing diameter of approximately 7 mm and a length of approximately 70 mm, is fitted into the barrel 20 of the gun. The laser 21 is fixed at the rear barrel end with a rubber ring 22 in the barrel 20 and positioned at the front barrel end with three threaded grub screws 24 , each offset by 120 ° in the circumferential direction in the tube wall. This allows the laser 21 to be aimed at the gun sight.

The arrangement of the rechargeable battery or rechargeable batteries 25 in the magazine slot 26 of a laser gun according to the invention is shown in FIG. 12. The housing 27 accommodating the batteries 25 consists of an upper part with chinch sockets 29 and a lower housing part 28 . The chinch sockets 29 take on chinch plugs 31 of an adapter 30 which has power connections 32 and which is fastened by means of a threaded bore 33 and screw connection in the handle 34 or in the magazine shaft 26 . The battery, the z. B. is a 4.8 V battery and has four P15 Lady cells and has dimensions of 30 × 12 mm, is designed as a dummy dummy and is inserted like a cartridge magazine in the magazine slot of the pistol.

To c) and d): When cocking or loading the gun, the circuit 35 from the connections 32 to the battery 25 to the laser 21 is closed or interrupted by actuating a microswitch 36 . When the shot is triggered, another laser microswitch 37 activates the laser 21 , which is located behind the trigger tongue. So that the laser can be activated in the trigger device at the moment of triggering the shot and thus when the trigger weight is overcome, the microswitch 37 is actuated via a threaded grub screw in the trigger tongue. Since the switching path of the micro switch in a special embodiment is only 0.2 mm and the trigger tongues after triggering the shot moves further backwards due to the trigger diarrhea, the microswitch 37 is movable in a separate housing in the direction of pressure under spring pressure against the Direction of actuation stored. In Figs. 15 and 16 of the trigger 4 is designated. 38 is the grub screw that can be screwed in or out. The switch housing 39 of the microswitch takes the switch body 40 , which is spring-loaded gela gert by a spring 41 in the switch housing 39 , and the switch button 42 is connected to the switch body 41 so that it protrudes from the switch housing 39 and from the grub screw 38 in Deduction 4 can be operated. In the illustration according to FIG. 15, the switch in the rest position and the trigger is shown in the unactuated position, while in Figure 16 the switches in the operating state Be., That is turned on and the trigger is shown in the actuated position.

Regarding e): The trigger device of the laser gun according to the invention is shown in FIGS. 4-9 in different operating positions. In order to enable continuous firing with the same handling as with a self-loading pistol, a constant trigger or a constant firing with the same trigger values, namely the preferred distance, preferred weight, pressure point, trigger weight and trigger diarrhea must be achieved with the laser gun according to the invention, although in the trigger device the "breaker function" is missing. This interrupter function is achieved with the help of a control bolt 43 , which interacts with the trigger rod 44 , and through a special formation of this trigger rod 44 . Here, an interruption between the trigger rod 44 and the transmission lever 45 , which corresponds to the transmission lever 7 in the illustration according to FIGS. 1-3, is achieved. Depending on the type of pistol used, a catch and other levers can be used instead. By the changed trigger rod 44 and by using the control bolt 43 , the trigger characteristic of the trigger is maintained and is analogous to that of a conventional Dienstpi stole. When the clamping handle 9 is pressed in, the pull-off process can be continuously repeated.

If the flag on the firing pin 10 is removed, the striking spring is no longer tensioned when the clamping handle is pressed in. The tensioned striking spring, however, has affected the trigger behavior. Since this spring force is only available when the first shot is fired and is then missing as a force for the trigger behavior, this spring force is replaced by the built-in special spring 46 for the transmission lever 7 ; this spring force acts as a constant component on the trigger behavior. So that the clamping handle 9 due to the lack of clamping force of the impact spring can not be pressed wall with less force, an additional spring 47 is provided which acts on the clamping lever.

As shown schematically in FIGS. 4 and 5 and shown in FIGS. 6-9 in the sequence of movements. The trigger device consists of the trigger 4 of the trigger rod 44 , the transmission lever 45 , the special spring 46 and the Zusatzfe the 47th The trigger 4 is mounted at 48 in the gun housing and articulated at 49 on the trigger rod 44 . The trigger rod 44 has a recess 51 in which the control bolt 43 can occur. The transmission lever 45 interacts with the trigger rod 44 and the control bolt 50 in such a way that when the trigger 4 is pressed, the trigger rod 44 is pivoted forward by the control bolt 43 and the transmission lever 45 is released. The special spring is connected to the transmission lever 45 so that it pivots it back into its rest position when released. If the trigger 4 is released, the trigger rod 44 again lies behind a nose 52 of the transmission lever 45 . Because the flag on the firing pin 10 has been removed, the striking spring is no longer tensioned when the trigger 4 is pressed in. This lack of spring force, which is only present when the first shot is fired and is missing as a force for the pulling behavior from further firing, is replaced by the built-in special spring 46 for the transmission lever 45 and acts as a continuous, equally large component on the trigger behavior. So that the clamping handle 9 cannot be pressed in with less force by the lack of clamping force of the impact spring, the additional spring 47 is provided, which acts on the clamping lever. In Fig. 6 the transmission lever 45 is in engagement with the trigger rod 44 and the control pin 43 shown. This corresponds to the rest position of the trigger device. If, as shown in FIG. 7, the trigger is pressed up to the pressure point, the trigger rod 44 pulls the transmission lever 45 upward at the front against the pressure of the special spring 46 . If the trigger is pressed fully, as shown in Fig. 8, the pressure point or the trigger weight is overcome. The trigger rod 44 is pivoted forward by the control pin 43 , the transmission lever 45 is released and rotates under the action of the special spring 40 back to the rest position. If, as shown in FIG. 9, the trigger 4 is released, the trigger 4 rotates into the rest position by the trigger spring. The trigger rod is placed again with its approach 53 under the transmission lever 45 .

Fig. 17a and 17b show in side and front view of the control bolt 50. Figs. 18a and 18b provide in side and front view of the trigger bar 44 with recess 51, linkage 49 and approach or recess 53.

Fig. 19 shows the auxiliary spring 47 as a torsion spring made of spring steel and Figs. 20a and 20b show the special spring 46 in the lateral and front view.
