DE19508966A1 - Protective gas mini-pistol with hand palm dimensions - Google Patents

Abstract

The mini-pistol has dimensions adaptable to a spectacles casing so that it can be concealed from the attacker in the user's pocket. It easily fits into the user's hand palm, and can be therefore fired without alerting the attacker. The pistol barrel (2) has a tetragonal casing over its entire length, with the cartridge chamber (4) of the same shape. A U-shaped slider (28) with two arrest positions can be moved over the entire length. Pref. the barrel and cartridge chamber form a tetragonal body of identical size.

Description

The criminal potential has increased steadily in recent years increased. In particular, robberies against individuals (hand robbery) or political or religious raids or rape and ill-treatment of women in confusion low-traffic street situations (underpass of foot after extensive "market research" reveal that the existing defenses are unsuitable and are ineffective. This situation has caused us a new defense weapon and also an improved one Defense method to develop, which the attacker a far higher risk than previously imposed. So that the robbery company significantly reduced and at the same time the penalty persecution can be improved.

The new defense weapon is so ver in weight and dimensions been reduced (despite the 9 mm gas cartridge) that it was in a pair of glasses lenetui can be accommodated. So that the weapon can steadily  be carried in your handbag or coat pocket. Consequently can never be seen from the outside whether the attacker is defenseless Glasses wearers or a ready-to-fight, quick-reacting Person with gas protection pistol in front of him.

The outer dimensions of the protective pistol are so handy dimensioned so that it is comfortable in the palm of your hand (outward hardly visible) while walking through a danger zone in the Can be worn hand ready to fire. The index finger lies permanently on the trigger and with a slightly angled arm can be surprisingly shot from the hip when in danger, so that the opponent does not have a conspicuous targeting process, as is more common wise before a robbery. With that the attacker's will to attack is significantly disturbed.

The gas pistol has only one shot for weight reasons addition, but the scattering effect and glare of the gas jet enables the attacked to flee immediately. Within of a few seconds can be reloaded, as usual 3 cartridges are also housed in the case. With others Persecutions can be of particular importance.

For defense, there are three cartridges (9 mm) with different fill lungs provided:

• a) Anti-glare protection with strong air pressure wave and bang effect  
• b) irritant gas cartridge with a relatively narrow jet effect, the causes considerable breathing difficulties in the attacker.
• c) "Color stink gas cartridge" that the attacker's clothing leaves a non-washable large stinky mark (similar to skunk defense), so that a police pursuit tion is made considerably easier. When using car or other escape aids are provided by the non-washable Leave more escape marks everywhere. The Stinky odor effect also results in considerable persistence Difficulty breathing for the attacker.
• d) Except for the above characteristics of gas cartridge action also still intends to additionally in the gas jet to spray chemical agents that un in the clothes visible and not washable leaves a mark that becomes clearly recognizable with UV radiation.

The features under points c) and d) are combinations that also may be present in a) and b). You are by the afterwir kung particularly suitable, the attack risk particularly through unexpected effect of the gas cartridge content on the attacker to make it incalculable.

In Fig. 1, a longitudinal section through the center of the gun housing is shown (section line AA in Fig. 2). The pistol consists of a box-shaped main carrier 1 , which is made of light metal (or plastic of high strength), and in which the pipe run 2 made of steel is equipped with the practically inaccessible lock 3 .

Aligned with the axis of the pipe run 2 , the steel cartridge housing 4 with the cartridge 5 . The steel cartridge housing 4 is supplemented by a firmly screwed steel back wall 6 with the conical opening 7 , so that the striking bolt 8 can act on the cartridge.

The steel cartridge housing 4 can be swung out to the side for removing the empty cartridge case and for reloading the new ammunition, as will be explained in the next FIGS. 3 to 6.

In Fig. 1, the box-shaped main carrier 1 is supplemented by an outer arch-shaped, also box-shaped end wall 9 , so that an overall stable box is created with the aid of two screws 10 . Within the arc-shaped box part 9 , a holding magnet 11 is accommodated in the lower corner, which magnetically holds the hammer 12 made of soft iron in the rest position of the pistol. The entire release kinematics, starting from the trigger 13 to the percussion hammer 12, are accommodated in the generally flat, tabular housing 1 and 9 and magnetically fixed in its starting position.

The kinematics of the gun consists of the following parts: the trigger 13 is mounted in the fulcrum 14 and moves the base head part 16 when the trigger 13 is actuated in the direction R via the pin bearing 15, which is fastened in the tube 17 by the pin 18 . This is the base bearing for the spiral spring 19 accommodated within the tube 17 .

In the rest position of the pistol (as shown in FIG. 1), the prestressed spring 19 presses on the head part 20 , which is movably mounted as a counter-bearing in the tube 17 and is limitedly movable with the tube 17 in a longitudinal slot 25 by means of a transverse pin 24 . The bias of the spring 19 is thus fixed via the tube 17 by the distance from the base head part 16 and the movable abutment 20 gela in the tube. The counter bearing pin 20 is defined in its position by the cross pin 24 and the slot end 25 in the tube 17 in its position, whereby the length of the biased spring 19 and thus the size of the spring preload is determined. (Further details in Figs. 9 to 12)

For the firing process it should be noted that at the end of the tube 17, the counter-head piece 20 is movably supported by the longitudinal slot 25 in the tube 17 , so that when the trigger 13 (in the direction of arrow R) is actuated, the spring pressure force can be increased further and the bolt 24 in is moved along the longitudinal slot 25 .

The counter head piece 20 is connected via the bolt 21 to the percussion hammer 12 and this is again supported with the bolt 22 in the box-shaped main main part 1 and 9 .

The triggering of a pistol shot thus takes place in such a way that the trigger 13 is pressed in the direction R and the spring in the tube 17 is compressed by the described suspension of components 15 to 17 , the hammer 12 initially by the permanent magnet system is held magnetically. Shortly before the end of the trigger 13 , the spring force has practically reached the holding force of the magnet and has reached the pressure point for triggering the shot.

As can be seen in Fig. 8, the pin 24 has arrived at further movement of the trigger lever 13 at the end of the slot 25 and thus a pressure point circuit is inevitably now completely ceases with the hammer 12 torn forcibly from the holding magnet 25 similar and the spring energy can the hammer 12 Accelerate radially around the axis of rotation 22 .

It is thus ensured that after complete travel of the pistol trigger 13 , the tensioned spring 19 with its energy content via the toggle 21 , 22, the hammer 12 opens with the necessary impact energy via the firing pin 8 on the patron ignition point and triggers the ignition.

After releasing the trigger 13 there is still a restoring force due to the preload, and the spring 9 brings the whole kinematics back to its starting position, ie the permanent magnet also fixes the basic position of the whole after the return of the hammer 12 by the magnetic holding force Gun mechanics.

In Figs. 3 to 7 are shown details of the structure of the gun.

For the cross sections shown in FIGS. 3 to 7, it should be noted in particular that the tubular pipe 2 made of steel in FIG. 1 has a square sheathing which essentially corresponds exactly to the square dimensions of the cartridge chamber 4 , so that the U-shaped slide 28 in its entire movement length, the cartridge chamber is covered as well as can be drawn off beyond the gun barrel. A brake spring is located in the inside of the U-shaped slide to ensure handling, supplemented by a raceway to prevent it from falling off to the outside.

It is the decisive function of this U-shaped slide the fissure gas escapes when positioned above the cartridge chamber to prevent hand protection. In addition, the Slider the construction of a laterally swiveling Cartridge chamber.

FIG. 3 shows a broken section of the line AA in FIG. 1. The suspension bolt 14 in the housing 1 of the pull lever 13 with the axis of rotation 15 in the base head part 16 shows the power transmission from the pistol trigger 13 to the spring 19 .

Fig. 4 shows the broken section B-B in Fig. 1, it can be seen from that the cartridge chamber 4 is such rotatably suspended on a bearing pin 4, by 90 degrees, that axis in eingeschwenktem state of the cartridge chamber, the cartridge axis and gun barrel aligned centrically becomes.

As can be seen from FIG. 5, the cartridge housing 4 can be pivoted out by 90 degrees for loading and unloading, so that the cartridge can be changed on the side of the pistol. For this purpose, the slide 28 must first be pushed forward in order to be able to swing out the cartridge housing.

As soon as the chamber 4 is reloaded with a new cartridge, the chamber 4 can be pivoted in again and the slide 28 can be withdrawn again. Thus, the slide 28 concentrates the chamber 4 exactly on the axis of the barrel 2 and thus makes the pistol ready to fire again.

Fig. 6 shows the existing steel cartridge chamber 4 into two section line representations which require no further explanation.

Fig. 7 shows the section CC in Fig. 1 and shows the cross section of the gun housing (without the arcuate end part 9 in Fig. 1). The box housing, which is open on one side, provides high mechanical stability for firing the shot, despite the small wall thicknesses, and facilitates the production of the flat plastic housing.

In Fig. 8 the trigger 13 is pulled in the direction R until it stops. The shot has been triggered and the kinematics is shown in a corresponding situation with the trigger 13 depressed.

The pressure force exerted on the bolt 21 by the trigger lever 13 to the highest tension of the spring 19 has now torn the bolt 22, the hammer 12 away from the holding magnet by the torque and, upon impact by the firing pin 8 on the ignition capsule, causes the cartridge to fire.

For a more detailed explanation, the blank 17 in this shot-triggered position of the kinematics is additionally shown separately from the overall view. It can be seen here that the bolt 24 has arrived in the slot of the tube 17 in the end position E of the slot 25 . As will be seen below in FIGS. 11 and 12, the length of the slot 25 in the tube 17 is through the moving operation of the kinematics (as in FIG. 1 and FIG. 8) to sionieren dimen functionally exactly in its length. It should be noted here that the trigger 13 is shown in the direction R in its end position and also the hammer 12 with firing pin 8 is shown in its end position for ignition of the cartridge.

Usually, the trigger 13 is released immediately after the shot, so that the spring tension 19 carries out the return of the entire kinematics and the situation shown in FIG. 1 is restored. This is of particular importance since the reloading process can only be carried out in the kinematic position according to FIG. 1.

In FIG. 8, the magnet holding system 25 is additionally shown separately from the side. The permanent magnet core 32 has two pole shoes 33 and 34 arranged on the side. As a result, the impact hammer 12 is held magnetically on its rear side with a precisely determined holding force (as can be seen in FIG. 1).

In addition, it can be seen in the overall drawing according to FIG. 8 that the slide 28 is arranged above the pivotable cartridge chamber 4 . As a result, when the shot is fired, the air gap gases emerging under ignition under high pressure in the column 4, which is necessary by the pivotably suspended cartridge chamber, protects ge against the hand of the gunner.

In FIG. 9 to 12, the kinematics is shown in its NEN Various operating states, wherein the position of the trigger 13 is shown in FIG. 1 only by the connecting line Zvi rule bolts 14 and 15.

Fig. 9 rest position of the gun: the magnet 25 magnetically holds the hammer 12 and the spring 19 causes that with little tension the trigger lever 13 (shown additionally in Fig. 1) is set at 75 ° of the connecting line 14-15 to the start of stroke . The bolt 13 lies on one side of the longitudinal slot in the tube 17 at the stop and thus defines the tensioning of the spring 19 .

Fig. 10 The trigger lever 14-15 has been moved to the 46 degree position and thus the spring tension has been increased and the bolt 13 is shortly before the end of the longitudinal slot in the tube 17th The spring tension force above the toggle lever 21 in conjunction with the hammer axis of rotation 22 almost reaches the adhesive force of the magnet 25 on the hammer 12 .

Fig. 11 In Fig. 11, the print dot position for the withdrawal at a level setting of 40 ° is reached, that is, the bolt 13 is is at the stroke end of the slot in the tube 17 and upon further movement of the trigger 14-15 necessarily the magnetic pull-off of the hammer 12 the magnet 25 surmounted with certainty and the hammer 12 is accelerated by the full energy content of the spring via the toggle lever 21-22 in its rotational movement about the axis 22 in order to hit the primer with corresponding kinetic energy.

Fig. 12 The firing pin 8 has ignited the cartridge by the kinetic energy of the hammer 12 with a high impact speed and after releasing the trigger 13, the bias of the spring certainly pushes the entire kinematics back into the initial position of Fig. 9. The trigger 13 has thus returned to the starting position and the hammer 12 comes back to the magnet 25 .

Additional note

As shown in Fig. 11 and Fig. 12 by a dotted line in the alternative, the bolt 13 has from the upper end of the slot when firing the shot (since the trigger cock 13 is still held at the end of the direction R) moved in the tube 17 to the opposite end, since the hammer 12 is still shown in the striking position on the primer. So that the length of the slot in the tube 17 is precisely defined for its function.

In Figs. 13 to 17 based on external views of the gun, the convincing ease of use is illustrated.

In Fig. 13, the slider 28 (which is determined in its end positions by the holding markings 29/30 in its range of movement) is particularly qualified for protecting the hand as well as for quick reloading by its double function in the two end positions.

Fig. 14 shows the spring-loaded spherical grid device 31 in section DD of Fig. 13. It should be noted again that the U-shaped slide 28 takes over both the centering of the cartridge chamber 4 in Fig. 1 compared to the cartridge barrel 3 in Fig. 1 and avoids any hand injury against escaping gases in the air gaps when firing.

FIG. 14 shows a section DD in FIG. 13. Here it can be seen that the slide 28 completely encloses the cartridge chamber 4 and the spring-loaded pen with a hemisphere-shaped tip in the markings 29 and 30 in Fig. 13 is able to mark the slide positions.

In Fig. 15, the slider 28 is moved forward to the front end of the tube up to the mark 29 and thus the patro nenkammer 4 can be pivoted 90 degrees according to Fig. 4 and Fig. 5.

Thus, when the slide 28 is returned by the pin 29, the empty cartridge (see FIG. 17) can be ejected, as is shown by a sectional view of the chamber 4 . The 9 mm cartridge is marked with 31 . Now, the empty swung cartridge chamber 4 can be loaded with new ammunition to be then returned back to its original position of FIG. 15 in order to make ready followed by return of the slide 28 in the position according to Fig. 13, the gun shot again .

Fig. 16 shows a section in the direction EE of Fig. 15, wherein it can be seen that the U-shaped slide 28 (slidable over the square-shaped cartridge chamber) has a lateral bulge, so that the cartridge sleeve 4 is made to measure by the stroke movement of the ejection pin 40 in Fig. 17 can eject.

Fig. 17 of the cartridge shell 31 is the pivoted cartridge chamber 4, with the U-shaped by the stroke movement of the slider 28 of the ejector pin 30 engages in the interior of the cartridge case 31, abuts the bottom on and accomplished the ejection.
