Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

 The invention relates to a protective device according to the preamble of claim 1.

[0002]

[Prior art]

There is always a danger of crime (kidnapping, robbery, assault, murder, etc.) in public spaces where citizens operate. Private spaces can be secured at the discretion of the citizens themselves. But,
Safety outside a four-walled house is directly related to the full presence of public safety agencies (such as police).

[0003] Municipalities have insufficient security agencies for many citizens, so they try to defend themselves. To defend, "free weapons" are basically used (weapons that can be purchased without a firearms license). These "weapons" (C
S-spray, gas-type threat weapon, signal weapon, etc.) can be used with restrictions.
Causes the attacker to be slightly injured, so that the attacker stops trying to do so.

One self-defense device is known from GB-A2 161 908. Known devices have only one operating module or several operating modules in one drum. Each operating module contained a shooting charge with a shooting charge in a ceramic plug. The charge can be ignited via electrical resistance. Each movement output was closed with foil to keep out dust. In addition, the operating module had one battery to power the known device, one electric lock switch, and one electric controller for controlling the firing device according to one shot or continuous firing. . The manufacture of this known self-defense device is expensive, complicated to use and troublesome.

[0005]

[Problems to be solved by the invention]

It is an object of the present invention to develop a true self-defense weapon which is unobtrusive but robust and easy to handle. In particular, it must be something that can be seen as a weapon at best (or not at all). The self-defense weapon of the present invention preferably maintains its function without trouble and maintenance for a long time (several years).

[0006]

[Means for Solving the Problems]

The problem is solved by providing the multifunction for the trigger of the release device of the self-defense device. The trigger acts on a high pressure pulse source that generates a high pressure pulse, which ignites the propellant charge. At the same time, the trigger acts on the electrical switching unit,
When the trigger is released and the firing charge is activated, it is preferably switched to another unfired movement. This switching is performed without using the explosive power generated by ignition. Battery-less switching will happen, but you'll have to check the charge from time to time. For the first time, the multifunction of the trigger simplifies the construction of the self-defense device according to the invention and keeps it ready for use without care for a long time.

[0007] It is a very simple and rugged structure, making the device inconspicuous and easy to operate by hand. Preferably, the plurality of movements are formed in an integrated motion module. Since the operating module or its movement is preferably designed to be non-rechargeable, it is a much simpler movement than a rechargeable movement and can be manufactured from cheap and less viscous materials. The entire operation module can be designed to be a suitable execution form and can be exchanged as a whole. Depending on the switching unit used, it can also be designed such that the unit can be exchanged alone or integrally with the operating module.

[0008] The self-defense device of the present invention can only be recognized as a weapon "at best". However, it is not set to be harmless. In the case of weapons, the setting as a harmless product is not permitted, for example, by German weapons law.

[0009] In addition to the priming and propelling charge ignited by the high pressure pulse, the firing charge includes a working charge. The active charge can be a single bullet (a bullet or a shot charge). Here, the active charges are liquid or gaseous stimulants and light rockets and color markers. The special shaping of the shooting charge is described below.

[0010] The device in the preferred execution form is designed as an integral one-piece synthetic product and the entire operating module is cast, so that the propellant charge of the movement of the operating module is not wet and unusable. . There are no sources of energy that will not be usable over time. This self-defense device can be used for several years without care, even in poor environments. The method of implementation will be described with emphasis on a simple and extremely inexpensive structure suitable for mass production.

The self-defense device has some moving parts, which results in a trouble-free structure. The self-defense device of the present invention is lightweight, weighing about 200 g, and is suitable for carrying because it is as small as a wallet.

This self-defense device has a light and compact design. It becomes portable with simple steps and methods. It can be used at any time with sufficient safety and can be used under extreme weather conditions. The energy to ignite the propellant charge is only made when needed. The compression tank also has no batteries and no springs to apply pressure for the priming. In addition, this self-defense device has ergonomic advantages. Unconsciously and automatically, the user grips the device correctly (think so-called pepper spray, which may spray itself). Unlike protective sprays that cannot be used above the head, they can be used anywhere. Other advantages and variations of the present invention are described below.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The self-defense device 2, shown in a vertical longitudinal section in FIGS. 1 and 2, is of a one-piece handy shape and matches any bag, pants pocket, skirt pocket. . No sharp edges on the outside. The self-defense device 2 is provided with a release device 3 which is cast and which operates with the operation module 1 and the operation module 1 which are entirely cast. Only the trigger 5 of the cast release device 3 can be moved with a finger.

The operating module 1 is designed to be non-refillable. The upper and lower movements 7a and 7b are arranged on the operation module. Each movement 7a, 7b has one shot charge 9, one shot charge 11, one priming 13
Contains. Both movements 7a, 7b are holes 15a, 15b drilled in the metal block 17. For this, a brass block is preferably used. It is also possible to choose to make the block 17 from, for example, a steel casting or an aluminum compression casting.

The operating module 1 is not in a form reminiscent of a shooting weapon, as is particularly evident from FIG. The sight gate, a typical element of pistols, has no sight. Both the operating module 1 and the movement end are entirely cast of synthetic material. The movement filling (here, for example, the shooting charge 9, the firing charge 11, the priming 13) is watertight because it is entirely covered with synthetic material. It is implied that the self-defense device 2 has one aiming device. The shape and operation of the aiming device are not described. An open movement is a threat and can inevitably trigger an unintended counterattack. In order to indicate the shooting direction, the upper part of the self-defense device 2 is a slider 12, which is distinguished from the other parts of the self-defense device 2 in shape and color.

In order to make the propellant charge 11 as small as possible, the thickness of the synthetic cover 14 over the end of the forward movement is reduced by the usual mechanical damage, for example in bags, trouser pockets, skirt pockets. Cover 14 thick enough not to break when damaged
The thickness should be such that it does not rupture, and that it can be broken down with minimal propellant charge energy. Otherwise, you would run out of energy when accelerating the shooting charge. A cut may be made in the cover 14 to make a predetermined breaking point.

The self-defense device 2 does not have the aiming device cast as described above. No cast grip. The lower part of the self-defense device 2 is a holder 18 and has an annular metal fitting 19. The annular metal fitting 19 separates the space 21, into which the index finger for operating the trigger 5 and the ring finger and the middle finger for stabilizing the self-defense device 2 are inserted, and the holder 18 is grasped. The annular fitting 19 serves as a trigger protector. If the self-defense device 2 is in the correct position, as in FIG. 1, a recess 23 is provided on the upper side of the trigger 5 opposite the extension 18 for placing the palm between the thumb and the index finger. The outer contour of the self-defense device 2 is a part important in terms of function (
Although the dents 23) are different, they are almost square.

From the release device 3, as already mentioned, only the trigger 5 is visible. The trigger 5 fits into the recess 27 of the holder 18 with a margin. The trigger 5 has two recesses 29a, 29b in which the front part 31 serving as the carrier of the switching unit 33 fits and the front part 35 of the ignition unit 37 is pushed in. The rearward-facing portions 39 and 40 of the switching unit 33 and the ignition unit 37 are
8 fits exactly. The trigger 5 acts on the center of the igniter 37. By this central action, the inclination of the release device 3 which has been loosely fitted is removed.

The front part 35 of the ignition unit 37 is a capsule. It receives the spring 41. The spring 41 acts on the hammer 43, which is stopped by a stop on the rearward facing portion 40. When such release inhibiting force is overcome by the strong pressure of the trigger 5, the hammer 43 strikes the piezoelectric crystal 45 in the ignition unit 37. The stop is lifted or restrained when about 5 kg of force is applied to trigger 5. This force is a protective measure for preventing an unintended release, and is useful for the self-defense device 2. By hitting the hammer 43, an electric high-voltage pulse is released, which is sent to the switching unit 33 via a conductor 47. When trigger 5 is released, spring 44 returns front portion 35 to the position of FIG.

[0020] The capsule-shaped return portion 39 of the switching unit 33 has two contacts 49a, 49b that are separated from each other but are electrically connected. Contacts 49a, 49
b is connected to the conducting wire 47. Portion 39 also has two contacts 49a, 49b
There are contacts 51a and 51b facing each other. The contact 51a is connected to the wire 7 by the movement 7
The contact 51b is connected to the initiator 13 of the movement 7b by a conducting wire 54. The contacts 49a, 51a and 49b, 51b are part 3
At 9, it becomes possible to connect to the slider 55 that slides coaxially. The slider 55 includes
There are contacts 59a and 59b loaded by the pressure spring 57, and these two contacts electrically connect the contacts 49a / 51a and 49b / 51b when the corresponding slide position is reached. The slider 55 has a hammer 60, and its front end supports one crosspiece 61, as shown in FIG. On the front part 31 there is a serrated fixture 64 with two further joining plates 63a and 63b. This will be the coupling part of the stop coupling, the manner of operation of which will be explained later. The crosspiece 61 is another connecting part of the stop coupling.

FIG. 5 shows the basic positions of the switching unit 33 and the ignition unit 37 shown in FIGS. 2 to 4, and a state in which the trigger 5 is pushed for the first defense fire. The arrow indicates the pushing direction. The hammer 43 strikes the crystal 45, causing a high-voltage pulse. This high-voltage pulse is transmitted to the switching unit 33 via the conductor 47. In the switching unit 33, the high-voltage pulse is transmitted to the contact 49a, and then the contact 51a is passed through the two contacts 59a and 59b of the slider 55 in the returning state.
, 39. The high-voltage pulse from the contact 51a is transmitted to the priming 13 of the movement 7a via the conducting wire 53 and ignites the priming 13 with an electric spark (of course, other ignition mechanisms may be used). When the trigger 5 is pushed in the direction of the arrow in FIG. 5, the front part 31 of the switching unit 33 slides to the right. Crossbar 61 is fixture 6
It slips off from two vertices 65 of 3a and 63b.

When the trigger 5 is released, the spring 44 pushes the trigger and returns to the initial state. The front part 31 places the crosspiece 61 on the two fixtures 63a, 63b. The slider 56 comes to the position shown in FIG. Here, a connection is made from the conductor 47 to the conductor 54 via the contacts 49b, 59a, 59b and 51b. Here, when the trigger 5 is pressed again, the crystal 45 produces a high-pressure pulse, which ignites the priming 13 of the movement 7b. If the trigger 5 is released, the subsequent release becomes impossible. Self defense device 2
Can no longer be used.

An apparatus having two or more movements is also possible. In this case, the switching unit is provided with n-1 separate contacts or a hammer 60.
Aside from the hammer resembling, put a crossbar apart from each other. The switching unit is lengthened accordingly. n indicates the number of movements.

7 to 10 show variations of the self-defense device 2 shown in FIGS. 1 to 6. In this self-defense device 70 having an operation module 71, a liquid stimulant 74 (eg, oleoresin capsicum) can be injected. Depending on the configuration of the operating module 71, gaseous stimulants, liquid color markers or light rockets and bullets can be fired. The operation module 71, unlike the operation module 1, has four movements 72a to 72d. The operation module 71 is not a fixed component of the self-defense device. The module can be placed on the basic body 73 (grip module) and becomes replaceable. The basic body 73 is reusable,
1 is a “one-way operation module”. The electrical connection of the priming 75 igniting the corresponding propellant charge 76 and entering the operating module 71 is made by means of electrical plug-in leads 77a,
77b. Overall shooting charge (working charge, propellant charge and detonator)
Is divided into capsules 79. All four capsules 79 are contained in the operating module 71. The operating module 71 can be exchanged in a simple manner, so that the basic body 73 and the operating module 71 are provided with matching devices, for example one tailcoat guide 78a, 78b. Furthermore, the operating module 71 has a single spring-operated lever 82a which, when retracted (FIG. 7), fits into a corresponding recess 82b in the basic body 73.

The cross section of the capsule 79 is a circle. A primer 75 is packed at the bottom of the capsule,
The projectile charge 76 is on it. Above the propellant charge 76 is an expansion space 80. The expansion space 80 is delimited by a sealed firing mirror 83 facing a space 81 for receiving a liquid stimulant 74. At the end of the capsule 79 facing the initiator 75, a thin film 8
There is a nozzle 85 closed at 4. The thin film 84 is designed to confine the stimulant 74 for a long period of time (several years) without trouble and to ensure that the stimulant 74 pops out when ignited. The nozzle 85 is designed to have, for example, an injection circle of 1/10 of the working distance.

To “explode” the stimulant 74, a release device 87 similar to the release device 3
The high pressure pulse is transmitted to the priming 75 described below via the switching unit 88 described below. This ignites the charge 76 (eg, black powder). When the propellant charge 76 is ignited, an inflation gas is generated which fills the inflation space 80. When the pressure in the expansion space 80 exceeds a specified value, the propellant charge mirror 83 comes off. The propellant charge mirror 83 presses the liquid stimulant 74 against the thin film 84, breaking the thin film. The stimulant 74 is ejected from the nozzle 85 in the above-described ejection shape. In the inflation space 80 between the propellant charge 76 and the propellant charge mirror 83, the pressure peak of the inflation gas generated when the propellant charge 76 burns is determined by the fact that the propellant charge mirror 83 causes the stimulant 74 from the nozzle 85 of the space 81. Is attenuated so as to accelerate the injection of the fuel gas substantially uniformly.

It is also possible to assign separate nozzles for each of the movements 72a to 72d as in FIGS. 7 and 8, or to move all movements with one nozzle.

The slidable trigger 89 of the basic body 73 is sealed with a ring seal 91 so that the self-defense device 70 can always be used even in a bad environment. By sealing, the ignition unit 92 having the piezoelectric high-voltage pulse source and the switching unit 8
8 is moisture proof.

In addition to the trigger 89, the release device 87 has an ignition unit 92 having a structure similar to that of the ignition unit 37 and having the same function. The ignition unit 92 has a first capsule portion 94 which is fixed to a ladder-type skirt plate 93 and a second capsule portion 95 which slides on the shaft with a margin but does not rotate toward the capsule portion 94. . The ladder type skirting board 93 is fixed to the basic body 73. The capsule portion 94 has a cylindrical end 96, which is one of the electrodes of the release unit and fits snugly into a depression 97 in the basic body 73. As a result, a “free” position of the ignition unit 92 is secured. Capsule part 9
At the bottom of 4, a piezoelectric crystal 99 having a recess 100 is arranged. As the depression 100 is pushed mechanically, the crystal 99 creates a high-pressure pulse, which ignites the corresponding priming 75. Further, a pressure spring 101 is provided in the capsule portion 94.
Which pushes another capsule part 95 towards the back 103 of the trigger 89. In this ignition unit 92, unlike the case of the ignition unit 37 partially pushed into the trigger 5, the capsule portion 96 is connected to the back side 103 by a spring. The mechanical connection between the ignition unit 92 and the switching device 88 takes place on the back 103 of the trigger 89.

The capsule part 95 has a hammer 105 which is pulled by a pressure spring 104. In the hammer 105, a plug 107 radially protrudes from the cover of the hammer 105, and the plug is provided in an opening 109 of the cover of the capsule portion 94. Opening 109
Has a rectangular shape, and an inclined portion 110 is formed in one of the rectangular vertical portions. The rim 111 of the opening 109 is perpendicular to the driving direction of the hammer 105. When the ignition unit 92 is in the stop position, the plug 107 is on the rim 111. In the cover of the capsule 94, a T-shaped depression 113 shown by a broken line in FIG. 10 is formed. The depression 113 is indicated by a broken line in FIG. 10 because it is located at the “cut” portion. To make a high-pressure impulse, only the part 114 whose axis moves and the T-shaped rung 116 that moves under the depression 113 in FIG. The rest is only needed for mounting.

The trigger 89 is pushed in the direction of A to create a high pressure pulse. Bottom 10 of trigger 89
3 pushes the upper side of the capsule part 95 against the force of the springs 101 and 104. The capsule part 95 is drawn into the capsule part 94 in the direction A. The opening 109 also moves in the direction A. The plug 107 remains in the recess 116 as it is. When pushed a further distance a, the plug 107 hits the beginning of the ramp 110 and is further pushed in a full distance b until it fits into the axially driven recess 114, FIG.
Is pushed up according to the position of. In addition, the stopper is opened by a pressure spring 104 in recess 114, which is stretched by a pushing distance b, to create a high-pressure pulse.
Hit 9 and hit hollow 100. In this state, the stopper 107 no longer hits the opening rim 111 because the opening rim 111 has already moved in the direction of A. When the trigger 89 is released, the pressure spring 101 pushes the capsule portion 95 in the opening 109 in a direction opposite to the direction A. The stopper 107 comes into contact with the opening rim 111 again, the stopper reaches the height of the recess 116, and returns to the initial state. Portion 95 of capsule portion 94 is slidable, but one end of pressure spring 104 is fixed to portion 95 and the other end is fixed to the top of the hammer so that the spring recesses plug 107 , It is possible to pull the spring 104 in the rotational direction. Two spring actions (linear action and rotary action) of the spring 104 are used.
The stopper 107 is inserted, and preparation for triggering is completed.

The high-voltage pulse produced by the crystal 99 is also transmitted first to the switching unit 88 in the case of the self-defense device 70. The switching unit 88 is designed such that not only can two priming agents be ignited one after another by two firing charges, but also more, for example four priming agents. There is no coupling with a serrated lever for sliding, but a serrated coupling 119 for rotation. The serrated coupling 119 is connected to a rotor 120 having electrical contacts. The rotor 120 is structured so as to be always in contact with the electrical connection line with the unburned detonator. Only when a high-pressure pulse is released is a new priming switched on (the contact position is on the already-burning priming, which can then be switched only the next time the trigger is triggered) ).

With regard to the indentation distance, a new initial connection with a new priming is made at the specified initial indentation distance, and the hammer 10 cannot be driven until it is pushed further deeply.
The distance is set so that 5 hits the crystal 99.

Initiator 75 is high resistance and works particularly well with high pressure pulse sources. With respect to the energy release from the voltage source, in a known manner, the energy is optimally released when the internal resistance of the voltage source is equal to the internal resistance of the consumer, here the initiator. Since the internal resistance of the high-pressure pulse source is high, the internal resistance of the initiator must be high.

Instead of the mechanical switching units 33 and 88 described above, it is also possible to use electrically operated switching units which do not require an additional switching voltage source.
One of the two electrodes can be connected to one pole of the piezoelectric crystal via a blocking diode. Choose a blocking diode that can contain a blocking diode with a higher blocking voltage in the conductor leading to the primer electrode. Diodes must be laid out so that they do not become short-circuited so that when current flows, the inside heats up and interrupts the current.

When the first high-voltage pulse occurs and there is an initial breakdown voltage, current flows through the first blocking diode in the lead for the first initiator. Current does not flow through another blocking diode. Because the breakdown voltage is higher than the initial voltage. If the first blocking diode is destroyed, the voltage of the high voltage pulse will not rise. Because current is created. The first blocking diode is destroyed in response to the current.
When the second high pressure pulse occurs, no more current is made to the first already burned initiator. The high voltage pulse rises until the second blocking diode is destroyed. The switching unit described here must always be replaced with the operating module.

[0037] Instead of a blocking diode, a corresponding transistor or tristar can also be used. Tristors and transistors can also be chosen with high passing voltages. There is no need to replace the electrical switching device. However, such circuits are slightly more expensive than the "non-burnable" semiconductor elements described above. Component prices are also high.

Instead of using semiconductors with different cut-off or passing voltages, it is also possible to use differently sized inductive inductances, which slow the current increase of the high-voltage pulse. For the first detonator, a current feeder with very low inductance would be chosen. For other initiators, the partial inductance is a value larger by one. The shape of the electrode ends should be such that, after successful ignition, no wires are formed between the electrode ends so that the distance between the electrode and the opposite side increases so that it burns. This is basically fixed. Since the ignition voltage of the first burning initiator is substantially higher, the inductance of the supply line is increased in the second ignition. The same applies to the subsequent detonator.

The self-defense device must be usable by persons who are not firing training. The problem is grasping the goal. Visible target firing lines are available to allow such people to make optimal use of the device. One small laser (He-Ne)
A laser, diode laser) or white light source is integrated into the device and its radiation axis is adjusted to correspond to the ballistic flight path and one effective range. The radiating ball of radiated radiated material can also be tracked by the imaging system in the same way as the injection charge injection circle.

A security lock with a firing element can be provided to prevent unauthorized use of the self-defense device. This safety lock preferably blocks the triggers 5-89 in the pull direction A. Key adjustable bolts can be used as safety locks. The safety lock is preferably provided on the grip.

In the above-described method of implementation, the active charge, the propellant charge, and the priming are placed in capsules having a round cross section. This cross section is not mandatory, especially for gaseous and liquid working charges. Oval or square cross sections are also possible.
