Abstract

The present application relates to devices and methods for introducing a filler material into the movement chamber of a firearm which has a movement chamber arranged in a housing of the firearm. The movement chambere is provided for a moveable component of the firearm or for a fluid that can move in the firearm, such that the movement chamber is at least partially filled and the filler material preferably solidifies when a condition arises in which the firearm is required to be rendered inoperative.

Description

The present invention relates generally to firearms and, more particularly, to apparatus and methods for at least partially permanently disabled one or more of its components in the event of unauthorized unauthorized use of firearms.

Background of the invention

In order to prevent the misuse of firearms, such as To prevent pistols, revolvers and rifles, various approaches are known. For example, access to a firearm can be prevented by allowing physical access to the firearm only to authorized persons (e.g., keeping the firearm in a gun cabinet). Furthermore, it is known to activate and / or deactivate electrical and / or electronic components of firearms depending on whether an authorized person operates the firearm (eg by means of a transmitter of the authorized person releasing a release to a receiver in the firearm - or blocking signal sends).

These approaches are i.a. so far prone to error, as the firearm itself remains functional and can be used in overcoming the security measures the firearm. Also, it is not possible with firearms, similar to an immobilizer of a motor vehicle to make a firearm software-based unusable.

In order to actually make a firearm useless, there are attempts to at least partially destroy the firearm by means of an explosive device arranged in the firearm. These approaches are susceptible to error, inter alia, for the following reasons. In some approaches, the explosive means are contained in devices provided separately from the firearm, which, for example, are to be introduced into the barrel or magazine slot of the firearm and consequently are only effective. Also, by the explosives surrounding people are injured. Furthermore, in these approaches mechanical components of the firearm are destroyed, which can also be replaced by unauthorized persons, such as the barrel. Object of the invention

Description of preferred embodiments

Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. The following statements apply, even if made with reference to a drawing, in principle for all illustrated and described variants of the present invention, unless expressly noted to the contrary.

1 schematically shows a firearm in the form of an exemplary pistol 2, without thereby restricting the present invention to such firearms.

The firearm 2 has a generally designated 4 housing, which may comprise several parts, such as a handle 6, in which generally housed (not designated) magazine and in the case of more recent types of firearms and electronic and / or electronic components can be. The latter can also or additionally be arranged in other areas of the firearm 2, for example in the area 12 of the closure and the like. The housing 4 of the firearm 2 shown also comprises a part 8 in which a barrel 10 is arranged and the part 12 which contains the closure (not marked here). The firearm 2 also has a tap 14. In the housing 4, a controller is further arranged, which is shown in Fig. 2.

FIG. 2 schematically illustrates a firearm 2 according to the invention with a controller 16. The controller 16 serves to control electrical and / or electronic components of the firearm 2 and in particular one or, as shown in FIG. 2, a plurality of so-called destruction units 18, 20 and 22. The term destruction unit should specify in particular their function to override a function of the firearm, that is to destroy, preferably permanently. In particular, it is provided that the function of an ner or more mechanical and / or structural components of the firearm to disable. This will be explained further below with examples.

The controller 16 and the destruction units 18, 20 and 22 are communicatively connected to each other, for example by wire, to transmit data and / or signals at least from the controller 16 to the destruction units 18, 20 and 22. There may also be provided information transfer from the destruction units 18, 20 and 22 to the controller, e.g. Transfer information about the functionality of the destruction units 18, 20 and 22 to the controller 16.

The controller 16 has a receiving part 24, which is integrated as shown in the controller 16 and for the representative in Fig. 1 an antenna for receiving (in other embodiments also for transmitting) wireless information is shown. In further variants, the receiving part may be a unit which is executed separately by the controller 16 and is arranged in the firearm 2, which unit is communicatively connected to the controller 16.

About the receiving part 16 information can be transmitted to the controller wirelessly to control the firearm 2 from the outside. In particular, it is provided for the present invention to provide the controller 16 information on the basis of whose presence and / or absence the controller 16 controls the destruction units 18, 20 and 22.

For example, the controller 16 may activate one or more of the destruction units 18, 20, and 22 when the controller 16 receives certain information and / or does not receive certain information. Examples of this are described in more detail below. Fig. 2 shows three destruction units 18, 20 and 22 without intending to be limited to this number. Any number or only a few units of destruction can be accommodated in a firearm. Criteria for the number of destruction units include available space in the firearm to what extent functions of a firearm are to be rendered unusable and under what conditions this should be done.

In the embodiment of FIG. 2, the destruction unit 18 is assigned to the cock 14, the destruction unit 20 to the firing pin of the firearm 2, and the destruction unit 22 to the closure of the firearm 2.

The firearm 2 is preferably such a controlled firearm that only under certain conditions (eg in and / or outside predetermined geographical areas (Eg rooms, open-air grounds, etc.), and / or in predetermined directions (in particular for firing released directions) and / or by authorized persons a firing is possible. The firearm 2 may be provided with information about whether a condition exists, whether a firing is permitted and / or not permitted, and / or whether an authorized person is handling the firearm, by means of a separate device 26. In Fig. 2, a device 26 is shown, which can wirelessly transmit information to the firearm 2. An example of such an enabling and / or blocking device 26 is, for example, a transmitter carried by an authorized person who can transmit authentication information to the firearm 2. The device 26 can also be a device which is arranged in an area in which the firearm 2 may be used and / or in which the firearm 2 may not be used. If the firearm 2 is in the corresponding area, the firearm 2 can be released for firing by means of such a device 26 or blocked to prevent a firing.

Regardless of the control of the firearm 2 with regard to its release and / or blocking, with regard to the destruction unit it is intended to activate it in and / or outside predetermined areas, e.g. when the firearm leaves a predetermined area (e.g., shooting range / facility, etc.) and / or enters a predetermined area (e.g., school grounds, authority, etc.). For this purpose, the determination of the position of the firearm, for example by means of a GPS location of the firearm can be done.

Additionally or alternatively, the destruction unit can be activated time-dependent. For example, it may be checked if a predetermined time has elapsed and, if so, the destruction unit activated. If one or more predetermined conditions are met within the predetermined time, the timing may be stopped and restarted so that once the condition (s) have been satisfied, the predetermined time is completely available again. Such conditions include the entry of a control command, code, etc. on the firearm itself (eg, by keying on firearm keys, by data transmission by means of a transponder) and / or on a separate, remote device, which will then issue a corresponding control command, code, etc. transmitted to the firearm. If such an input occurs before the predetermined time has elapsed, the (automatic) time-dependent destruction of the firearm is prevented within the currently running predetermined time. Thereafter, the predetermined timeframe begins again, in which the firearm is reset either with regard to the passage of time or after which the firearm (automatically) is destroyed in a time-dependent manner. Additionally or alternatively, the time reset can also be position-dependent, eg by bringing the firearm into a predetermined area (back), for example into a gun cabinet.

The destruction unit can be intentionally destroyed at the request of a person, for example by a control command, code, etc. on the firearm itself (eg by entering by means of buttons on the firearm, by data transmission by means of a transponder) and / or on a separate, remote device , which then transmits a corresponding control command, code, etc., to the firearm. A blocking and / or release of the firearm can (supplementary or alternative) by voice control / voice recognition / voice activation, radio controlled (eg by means of special transmitters and / or a radio communication network, eg GSM, UMTS, LTE, W-LAN) and / or control signals carried out, for example, via a communication network (eg Internet, Intranet, W-LAN) are transmitted to the firearm. In the latter case, the control signals can be transmitted wirelessly to the firearm, for which it has a corresponding receiving device, such as. one for W-LAN, and / or wired when the firearm (e.g., in a gun cabinet) is connected to a corresponding communications interface. Furthermore, the blocking and / or release of the firearm can take place by means of image recognition. Thus, for example, by means of an image capture device that is structurally connected to the firearm or integrated into it or that is communicatively coupled as an external component with the firearm. By image recognition, e.g. the face, hand, or other body part (or parts thereof) of a current user is detected and checked to see if it is an authorized user or not. The check may e.g. by comparison with a database or database storing image data of body areas of authorized users.

Furthermore, it is provided to make the firearm unusable by the destruction unit is activated externally controlled. This can be done, for example, by voice control / voice recognition / voice activation, radio-controlled (eg by means of special transmitters and / or via a radio communication network, eg GSM, UMTS, LTE, W-LAN) and / or by means of control signals, for example via a communication network (eg Internet, intranet, W-LAN) are transmitted to the firearm. In the latter case, the control signals can be transmitted wirelessly to the firearm, for which it has a corresponding receiving device, such as one for W-LAN, and / or wired, when the firearm (eg in a gun cabinet) is connected to a corresponding communication interface. Furthermore, the activation of the destruction unit by means of Image recognition done. Thus, for example, by means of an image capture device that is structurally connected to the firearm or integrated into it or that is communicatively coupled as an external component with the firearm. By image recognition, for example, the face, the hand or another body part (or parts thereof) of a current user can be detected and checked whether it is an authorized user or not. For example, the check may be made by comparison with a database or database storing image data of body areas of authorized users.

Embodiments of destruction units according to the invention are described with reference to FIGS. 3 to 10. Unless otherwise stated, statements relating to the various embodiments basically apply to all shown and described variants of destruction elements according to the invention.

FIG. 3 illustrates a destruction unit 30 with a housing 32, which may be formed, for example, in the form of a sleeve of zirconium oxide. In the housing 32, a Anzündelement 34 is arranged, which also serves as a base or ground for the other components here. The lighting element 34 may be provided as a wire lighter which may be electrically activated by means of two terminals 36 and 38, e.g. can be formed on a pressure and heat-resistant glass-metal socket.

On the ignition element 34, a primer 40 is arranged, which may have, for example, a Cu-O / Zr mixture. The ignition charge 40 may be e.g. pasty to be applied to the ignition element 34 and / or plastic bound. The temperature at which the ignition charge 40 is activated may be e.g. at about 480 ° C.

The space lying above in the housing 32 is substantially filled with a heating pack 42, in which a filling set 44 is embedded so that it is exposed at the upper housing opening 46. The heating set 42 may e.g. have a Ti / mo0 mixture. The heating set 42 may also be e.g. be pasty applied and / or plastic-bound.

The filling set 44 can comprise, for example, an aluminum alloy which can form an aluminum foam by heating, or a Ti-based intermetallic reactive mixture, preferably with a high reaction temperature, which can form a metallic hard material by heating. The operation of the destruction unit 30 is substantially as follows. By applying an electrical voltage to the terminals 36 and 38 of the ignition element 34, the ignition charge 40 is ignited, which generates heat and pressure thereon and thus acts on the heating unit 42. The pressure acting on the heating set 42 and thus also on the filling set 44 from the ignition charge 40 conveys the heating set 42 and the filling set 44 out of the housing 32 through a housing opening 46. The housing opening 46 forms the outlet opening of the destruction unit 30 here from the primer 40, the heater set 42 is also ignited thereby generating heat, preferably for a longer period of time than the primer 40 (eg 50-100 ms). Longer heat generation is required in particular when the filling set 44 requires a high initiating energy for its conversion.

When using a filling set 44 comprising an aluminum alloy, an aluminum foam is produced by supplying heat (e.g., over 450 ° C) to form, as described below, e.g. to fill a room or cavity (at least partially)

When using a filling set 44, which comprises a Ti-based intermetallic reactive mixture, an exothermic reaction is caused by heat supply, the reaction product is a metallic hard material. This can be used, as described below, e.g. to fill a room or cavity (at least partially)

The embodiment of a destruction unit 30 illustrated in FIG. 4 differs from the embodiment of FIG. 3 in that a cover 48 with a substantially central passage 50 is arranged at the opening 46 of the housing 32.

The cover 48 may be formed in the form of a cover layer which is applied to the surfaces exposed to the housing opening 46 (not labeled) of the heating unit 42. The cover 48 may alternatively or additionally comprise a ring (e.g., plastic and / or metal).

In all cases, the passage 50 of the cover 48 is preferably formed so that the exposed at the housing opening 46 region of the filling set 44 is not or only slightly covered. In such embodiments, the passage 50 forms the outlet opening of a destruction unit.

The cover 48 provides for a more directional manner in which the heating pack 40, and in particular the filling set 44, are conveyed out of the housing 23 when activated. Insbesonde- The heat dissipation from the heating set 42 via the opening 46 is at least reduced by the cover 48, so that more heat of the heating set 42 can be supplied to the filling set 44. Furthermore, through the passage 50, the discharge of the filling set 44 is better controlled.

FIG. 5 illustrates the above-mentioned possibility provided according to the invention for filling (at least partially) a space 54 or cavity provided by a body 52 by means of a destruction unit. Fig. 5 shows the embodiment of Fig. 4, in the place of any other embodiment of the invention can be used. Upon activation of the ignition element 30, as explained above, the filling set is conveyed out of the housing 32. To fill the space 54 (at least in part) with material and / or reaction products of the fill set 44, the destruction element 30 is arranged so that the passage 50 substantially coincides with an opening 56 of the space 54. Upon activation of the destruction unit 30, material and / or reaction products of the fill set 44 are conveyed through the passage 50 of the cover 48 into the space 54 and at least partially fill it. Preferably, the filler solidifies.

Depending on the type of filling set 44 used, the space 54 is (at least partially) filled in such a way that the filling material firmly bonds to the wall of the space 54 and is difficult, if at all, to remove it from the space.

In principle, the variant of FIG. 3 can also be used. Then, the destruction unit 30 is disposed on the body 52 so that the portion of the filling member 44 exposed at the opening 46 substantially coincides with the opening 56 of the space 54. Thus, the space 54 can also (at least partially) be filled with material and / or reaction products of the filling set 44. When using a destruction element 30 without cover 48 an improved backfilling of the space 54 is achieved when the destruction element 30 (eg by means of contact pressure) is firmly connected to the body 52, preferably such that even upon activation of the destruction element 30 this and the body 52 are interconnected and do not move relative to each other substantially. This avoids that material and / or reaction products conveyed out of the housing 32 do not enter the space 54 and accumulate, for example, on the underside 58 of the body 52. In the variant of FIG. 6, an insert 60 is arranged in the housing 32. The insert 60 has a space 62, which provides for defined internal structures on the one hand for receiving in particular the heating set and the filling set and on the other hand for material and / or reaction products from the housing 32 preferably targeted to challenge when the destruction element 30 is activated.

The insert 60 has a mouth region 64 and a region 66 which is provided for receiving the components 34 to 44.

As illustrated in FIGS. 7 and 8, the orifice area 64 and / or the receiving area 66 may be varied (for example, depending on the particular application) to control the exit behavior of material and / or reaction products from the housing 32 or sets of heating elements / or quantities to vary. For example, by increasing or decreasing 68 of a receiving area 66 stronger or weaker reactions, larger or smaller quantities, etc. can be achieved. By varying 70 of the mouth region 64, different "nozzle" geometries can be achieved by means of which, for example, the exit velocity of material and / or reaction products can be influenced.

The insert 70 preferably comprises a material which is thermally stable under the exclusion of oxygen, for example graphite. Fig. 9, like Fig. 5, serves to illustrate how a space 54 can be at least partially filled. Fig. 9 shows an application in which (for structural reasons, for example) there is a distance A between the filling element 30 and the body 52. In such cases, to at least partially fill the space 54 with material and / or reaction products from the destruction element 30, the use of an insert 60 may be advantageous.

Fig. 10 shows schematically the production of a destruction unit 30 according to the embodiment of Fig. 6. First, an ignition element 34 is arranged in the housing 32, for example by gluing. Thereafter, an insert 60 is inserted, and the ignition charge 40 is placed on the ignition element 34. In variants, preferably the ignition element 34 is provided in advance with the ignition charge 40 and arranged together in the housing 32. Furthermore, it is possible, after arrangement of the ignition element 34, first to arrange the ignition charge 40 thereon and then to introduce it into the housing 32 together. In the next step, a heating set 42 is arranged in the receiving region 66 of the insert 60. By means of a tool 72, a receptacle 74 is formed in the heating unit 42, in which a filling set 44 is arranged in the next step. Depending on the type of materials used, in particular for the heating set 42 and / or the filling set 44, the entire arrangement can then be dried. By means of a lid or closure 76, the destruction unit 30 can be closed to pour it after manufacture until its use / installation.

Referring to FIGS. 11 and 12, basic operations of a destruction unit according to the present invention will be explained. Fig. 1 la and 1 lb illustrate a destruction unit ZE, with a positive disabling is achieved. Figures 12a and 12b illustrate a destruction unit ZE that achieves substantially frictional depletion.

Figures 11 and 12 illustrate functionally embodiments in which a movable component BK movable in directions B relative to a stationary part ST is rendered unusable, can no longer be moved in direction B by moving a movement space BR with it Filling material FM is at least partially filled.

FIG. 11a illustrates an arrangement with a movable component BK which is movable in directions B in a relatively stationary component ST. In order to move the movable component BK in the stationary part, there is provided a movement space BR into which the movable component can be moved in and out. This is illustrated in Fig. 1 1 a by the dashed line.

The arrangement of FIG. 1 a has a destruction unit ZE, of which embodiments are described above with reference to FIGS. 3 to 10. Of the destruction unit ZE is in Fig. 1 la simplifying only a filling set FS indicated. The destruction unit ZE has an outlet opening A, which is in fluid communication with an inlet opening E of the movement space BR and thus in fluid communication therewith. The outlet opening A and the inlet opening E form a material passage.

In the state shown in Fig. 1 la, the arrangement is functional, that is, the movable component BK is movable.

In order to make the arrangement inoperative / unusable, the destruction unit ZE is activated, in particular by firing its destructive element. The activation causes, as described above, the filling set from the destruction unit ZE is conveyed through the outlet opening A and the inlet opening E in the movement space BR. In this Operation, at least in the movement space BR, the filling set, as described above, implemented in filler FM. The filling material FM at least partially fills the movement space BR such that movements of the movable component in the direction B are no longer possible.

For this purpose, it is not necessary, as illustrated simplistically in FIG. 1 b, to completely fill the movement space. The functional inability of the arrangement of FIG. 11 is achieved when the movement space BR is filled with filling material FM to such an extent and / or at such locations that the movable component BK can not be moved into the movement space BR. Movements of the movable component BK in the opposite direction are prevented when the filler FM at least partially connects to the front side FS of the movable component BK.

The state shown in Fig. 1 lb shows the arrangement in an inoperative / unusable made state.

Embodiments in which the principle illustrated in FIG. 11 is used are also referred to as form-locking embodiments. Fig. 12a illustrates an arrangement with a movable component BK which is movable in directions B relative to a stationary part ST. The movable component BK in Fig. 12a has a recess N. The movement space BR of the arrangement of FIG. 12 comprises a movement space BRa that is comparable to the movement space BR of FIG. 11. Further, there is a movement space BRb, both movement spaces BRa and BRb are required for the arrangement to be functional, that is, the movable component BK can be moved. Again, a destruction unit line, simplistic shown with a filling set FS, available, which is connected via an outlet opening A with an inlet opening E to the movement space BRb and thus in fluid communication therewith.

Fig. 12a shows the arrangement in the functional state.

In order to make the arrangement inoperative / unusable, ie to prevent movements of the movable component BK, the destruction unit ZE is activated. This leads to at least partial filling of the movement space BRb with filling material FM. Due to the filling material FM present in the movement space BRb, the movement space BRb is not or not completely available, so that the movable component can not be moved.

In such arrangements, smaller interfaces between filler FM and movable component BK are available as compared with FIG. 11. Such arrangements can be compared with the action of a brake pad of a bicycle brake, which acts on a wheel rim during braking. Therefore, such arrangements may also be referred to as frictional arrangements. A combination of positive and frictional configurations can be achieved by combining the arrangements of FIGS. 11 and 12 by providing two destruction units ZE which at least partially expire the movement spaces BRa and BRb. Fig. 13 schematically illustrates an embodiment for disabling a firing pin of a firearm. FIG. 13 schematically shows a partial cross-sectional view of the firearm 2 from above through the part 12 comprising the shutter 82 and a firing pin 78. The firing pin 78 is movable in the directions B. In order to ignite a cartridge arranged in a cartridge chamber 80, the firing pin 78 is moved to the left as shown in FIG. This is illustrated by the arrow Z. Thereafter, the firing pin 78 is moved back in the opposite direction. If the firing pin 78 is movable, he and thus the firearm 2 is functional and ready if their other components also work properly and not, as described below, were rendered inoperative / unusable.

For movement of the firing pin 78, a movement space BRb is provided, which is basically comparable to the movement space BRb of FIG. The firearm 2 has a destruction unit ZE, which is denoted by 20 in the above FIG. 2. To disable the striker 78, i. To prevent a movement of the same permanently, the destruction unit ZE (20) is activated and thus introduced filler in the movement space BRb. As explained with reference to FIG. 12, movements of the firing pin 78 are thereby prevented.

FIG. 13 shows a further movement space BRa, which is comparable to the movement spaces BR of FIG. 11 or BRa of FIG. 12. By means of a further destruction unit, as explained above with reference to FIG. tively the movement space BRa are at least partially filled with filler material to prevent movements of the firing pin 78.

FIG. 14 illustrates a variant for rendering a closure 82 of the firearm 2 useless. 14 schematically shows a cross-sectional view in the region of the part 12 of the firearm 2. There, the closure 82 is movably arranged in the directions B. By means of a destruction unit ZE, which is designated by 22 in the above FIG. 2, as described above, a movement space BRb can be filled with filling material (at least partially). This prevents the shutter 82 from being moved. Further, the embodiment shown in Fig. 14 includes two spaces 84 and 86. Instead of the spaces 84 and 86 shown, an annular space may be used. When the destruction unit ZE (22) is activated, filling material is also introduced into the spaces 84 and 86 (or the annulus). By means of the filling material in the movement space BRb and in the spaces 84 and 86, a preferably fixed, non-detachable connection of the closure 82 is achieved with a part 88 of the grip in which the spaces 84 and 86 are arranged. This connection provides an additional safeguard which prevents removal of the closure 82.

FIG. 15 shows a further variant in order to render the closure of a firearm inoperative / useless. Apart from the following explanations, the statements relating to FIG. 14 also apply to FIG. 15. In the embodiment of FIG. 15, a movable lock 90 is arranged between the movement space BRb and the destruction unit ZE (22). Upon activation of the destruction unit ZE (22), the lock 90 is moved by the exiting filling set or the generated filling material into the movement space BRb. It is envisaged that filling material also enters the movement space BRb. By means of the filling material, the lock 90 is fixed in the movement space BRb. Movements of the closure 82 are then no longer possible. Furthermore, provision is made for filling material to be present between the lock 90 moved in the movement space BRb and the destruction unit ZE (22) in order to backfill the lock 90 and thereby fix it in addition.

Fig. 16 illustrates an embodiment for rendering a cock of a firearm inoperative / unusable. Fig. 16 shows schematic cross-sectional views of the part of the firearm 2, in which the tap 14 is arranged. The cock 14 is rotatably supported by a shaft 92 in the handle. The cock 14 has a recess N, which defines a movement space BRb. Adjacent to the movement space BRb, a destruction unit ZE, which is designated by 18 in FIG. 2, is arranged in the grip piece. When activating the Destruction unit ZE (18), the movement space BRb is at least partially filled with filling material, so that the cock 14 can not be pivoted, and thus rendered inoperative / unusable. Fig. 16 illustrates an embodiment in which a fluid provided for movement space of the firearm 2 with filler material is at least partially filled. Fig. 17 is based on a firearm, which is designed as a so-called gas pressure loader, ie a firearm, is used in the case of delivery of a shot in the barrel generated gas pressure for reloading a new cartridge. Fig. 17 shows a section of the area of such a firearm in the region in which a gas bore 94 is arranged. The gas bore 94 provides a channel-like fluid connection between the interior 95 of the barrel 10 and a hollow cylinder-like space 96, for example. Upon delivery of a shot 10 resulting pressure is passed through the gas bore 94 in the space 96, where by means of this gas pressure, an actuating element 98 (eg punch) is moved in the direction of the arrow 100 in the run 10. This movement of the actuator 98 is typically used in conjunction with other downstream components to reload the firearm. After reloading the actuator 98 is moved back in the opposite direction, for example by means of spring before voltage. Adjacent to the gas bore 94, a destruction unit ZE is arranged, which, when activated, introduces the gas bore 94 in such a way that there is no fluid connection between the inner tube 95 and the space 96. This closure has the consequence that the firearm is then no longer usable insofar as its function to automatically reload is no longer available.

FIG. 18 illustrates an embodiment in which a board 102 of the firearm can be destroyed by means of a destruction unit ZE. In contrast to the variants described above, in this embodiment, the board 102 is substantially thermally damaged or destroyed. Reference icon list
