Description

[0001] The invention relates to a device for preventing the continuation of a burglary into or in a building by means of a substance comprising a gas.

[0002] From the provider Verisure ® It is known that a fog-like visual barrier ("smoke barrier") can be used to protect business premises, as it obscures the view of burglars. Shock sensors on windows and doors, as well as motion detectors, report attempted break-ins to an emergency call and service center. At the control center, staff can monitor the situation using live audio and video recordings. If burglars are indeed present, the visual barrier is activated, and the police, the building owner, and, if necessary, emergency services are notified.

[0003] This procedure is very complex due to the necessary involvement of the emergency control center.

[0004] The idea of ​​using gas to deter burglars is also found in the prior art. In many cases, this involves a kind of trigger mechanism acting on an aerosol can. For example, DE 41 33 110 A1 shows a mechanism that actuates an aerosol can valve. DE 88 04 829 U1 shows the use of a tear gas cylinder and a radio receiver for triggering the gas.

[0005] From DE 203 16 116 U1, it is known to release an irritant for burglar deterrence. A sensor (e.g., a light barrier) sends signals to a receiving element in a housing, which then causes the release of gas.

[0006] WO 2012 / 085606 A1 describes an electronic triggering of the release of irritant gas by a wake-up signal, for example from a central unit.

[0007] The GB 2 324 636 A reveals a wireless triggering of an anti-burglar device.

[0008] From US 8 692 670 B2 it is known that a spray nozzle is arranged in or on a door and repels burglars there.

[0009] US 10 366 589 B2 also concerns the defense against intruders (or assassins).

[0010] US patent 11308782B1 describes a self-contained defense device that can be controlled from a central location; for example, the spray direction can be adjusted. Artificial intelligence is used.

[0011] A tear gas dispenser integrated into the door is known from US 2012 / 0325127 A1.

[0012] US 2019 / 0151691 A1 describes the embedding of the dispensing devices in house walls, whereby dosing is possible.

[0013] The EP 3 853 548 B, the US 2025 / 0218276 A1, the US 10 507 793 B1, the US 12 400 533 B1 and the US 11 636 745 B2 reveal the use of artificial intelligence in systems for burglar prevention.

[0014] German patent DE 34 46 815 C2 demonstrates the defense against a burglar using spray applied directly at a door. A solenoid valve is used.

[0015] DE 101 48 641 A1 concerns the use of a pressurized container for spray liquid. This container includes a switchable valve.

[0016] DE 10 2007 021 267 B4 mentions a metered release of CS gas.

[0017] US patent 12 131 615 B2 deals, among other things, with the targeted selection of the spray triggers to be activated from several such spray triggers.

[0018] The current state of the art is based on the idea of ​​using a spray can that can be easily purchased as an accessory. This has disadvantages, such as a limited range for the gas supply.

[0019] The object of the present invention is to provide an improved device for preventing the continuation of a burglary.

[0020] The problem is solved by the device with the features according to claim 1 and the gas delivery device with the features according to claim 16.

[0021] The device according to the invention for preventing the continuation of a burglary into or in a building by means of a substance comprising a gas has: - At least one detection device to record unauthorized entry into a private area; - a data processing facility; and - at least one substance dispensing device for dispensing the substance, comprising a storage unit in which the gas is under overpressure, a valve, and an electrical circuit, wherein the valve can be brought into an open position by the electrical circuit so that the substance automatically dispenses, wherein the overpressure is between 3 and 10 bar, preferably more than 4 bar and particularly preferably at most 6 bar, and wherein an outlet leading over the valve opens into a dispensing hose, the respective outlet openings of which are spatially separated from the storage unit, wherein the spatial separation is provided by passing the dispensing hose through an obstacle and / or by a minimum length of the dispensing hose up to a first outlet opening of 2 m, preferably 3 m, further preferably 5 m; - wherein the at least one detection device has a transmitter and the substance delivery device has a receiver, wherein the data processing device can determine whether and when a signal is received by the receiver as a result of a signal emitted by the transmitter, wherein the receiver serves to activate the electrical circuit upon receipt of a signal in order to bring the valve into the open position and thus cause the substance to be released.

[0022] The combination of the storage device with the gas under particularly high overpressure and the valve makes releasing the substance with the gas very simple, as the valve only needs to be opened (moved to the open position), and the gas then escapes automatically due to the overpressure. Control by human operators (such as those at a control center) is therefore unnecessary. The invention thus departs from the use of conventional aerosol cans. Due to the overpressure of more than 3 bar or more than 4 bar, the substance can travel through extensive hose connections precisely to the location where the intruder needs to be repelled.The aforementioned spatial separation, in the variant where the delivery hose has a minimum length of 2 m, preferably 3 m, and further preferably 5 m to a first outlet opening, ensures that the substance delivery device can be discreetly installed, while the release of the substance / gas can be concealed from the intruder, for example, even located away from the storage unit. As explained below, such a first outlet opening can be integrated into a building element, such as a window or door. There may only be one (the first) outlet opening; however, the combination of high pressure with spatial separation also allows for the use of two, three, or more outlet openings to precisely target (or at least deliver) the substance to the correct location, far away from the storage unit.

[0023] Preferably, a measure is taken to ensure that the pressurized substance is released exclusively to intruders upon unauthorized entry into a private area.

[0024] According to a preferred embodiment, particularly for providing this type of measure, the housing of the substance dispensing device is designed as a highly stable, tamper-proof unit. It comprises a base or main body milled from a solid block of aluminum and a precisely manufactured lid (made of aluminum or another metal), which are gas-tightly connected to each other by means of a circumferential, chemical- and pressure-resistant seal. This design ensures maximum mechanical stability and tamper resistance, so that even in the event of external force or deliberate manipulation attempts, uncontrolled release of the substance is reliably prevented. Preferably, the wall thickness of the main body and / or the wall thickness of the lid is at least 1 cm and, more preferably, at least 2 cm.This wall thickness, which must be traversed, acts as a barrier, ensuring that the gas does not accidentally escape into the environment.

[0025] The housing contains all critical components – especially the memory, solenoid valve, electrical circuitry, receiver and power supply – protected against tampering.

[0026] The gas leaves the housing exclusively via a specially designed pressure line that leads out of the sealed housing. The pressure hose used is high-pressure resistant, chemical-resistant, and suitable for concealed installation through walls, ceilings, or other building structures. This allows the actual output module, e.g., with one or more targeted outlet openings, to be positioned remotely from the housing (i.e., spatially separated from the storage tank) and concealed within the area to be protected.

[0027] This significantly hinders access to the gas source and the dispensing module for burglars or saboteurs. The entire device thus achieves a very high level of operational reliability and protection against sabotage, manipulation, and external influences.

[0028] According to a preferred embodiment, the data processing device is designed to collect all signals received from transmitters of the at least one detection device and to determine, based on the signals, whether and, if applicable (especially in the presence of a plurality of substance delivery devices), which of the at least one substance delivery device receives a signal to activate the electrical circuit.

[0029] The data processing unit performs tasks comparable to those of the control center. By determining, based on the signals, whether a substance delivery unit receives a signal, the task previously performed by the control center in the known state of the art is automated.

[0030] According to a preferred embodiment, the data processing device is also designed to receive signals from at least one further detection device, such as a microphone and / or a camera, and to use these signals, preferably with the aid of a machine learning model, to perform a verification and / or a final determination.

[0031] When audio signals are received from a microphone or image signals from a camera, or both, verification can now be automated by artificial intelligence (machine learning model), similar to what was previously done by the control center.

[0032] According to a further preferred embodiment of the invention, the gas comprises (or is) CS gas, namely 2-chlorobenzylidene malononitrile. This gas belongs to the group of tear gases and takes effect immediately upon release. It causes severe eye irritation, namely tearing, burning, and temporary visual impairment. It causes respiratory irritation, namely coughing, shortness of breath, and a burning sensation in the mucous membranes. It also causes skin irritation, namely a burning sensation on unprotected skin. The effect occurs within seconds and lasts for approximately 30 minutes, depending on the concentration and exposure. The burglar is disoriented and unable to continue acting. The use of CS gas interrupts the intrusion in a particularly effective manner.

[0033] According to a preferred embodiment of the invention, the valve comprises a solenoid valve. It is preferably normally closed (closed by de-energizing). It can be a brass 1 / 8" FSA solenoid valve for 12V DC operation at a pressure range of 0 to 10 bar. The use of a solenoid valve makes tampering less likely, thus enabling the aforementioned measure to be implemented in this way.

[0034] In connection with the solenoid valve, but also in general, the electrical circuit can include (or is) a relay circuit.

[0035] According to a preferred embodiment, the electrical circuitry of the substance dispensing device can be supplied with electrical energy from an electrical energy storage device, such as a rechargeable battery or a battery. Thus, the system itself, and in particular the substance dispensing device, can operate autonomously, and no mains connection is required. It can therefore be easily installed in locations where no mains connection is available, for example, on doors, windows, or exterior walls.

[0036] According to a preferred embodiment, the transmitter of the at least one detection device is designed to output wirelessly transmitted signals and / or the receiver of the at least one substance delivery device is designed to receive such wirelessly transmitted signals. By using wireless signal transmission, the detection devices and / or the substance delivery devices can be positioned almost arbitrarily and, in particular, do not need to be coupled to each other, nor to the data processing device, which, as an intermediate device, can itself be equipped with a receiver and / or a transmitter in order to receive signals from the at least one detection device and / or send signals to the at least one substance delivery device. However, any combination of wired and wireless transmission is possible.The detection devices can transmit data to the data processing unit via wired connections, optionally in combination with wireless data transmission from other detection devices. Furthermore, wired signal transmission to at least one substance delivery unit is also possible, again optionally in conjunction with wireless signal transmission to other substance delivery units.

[0037] In connection with the wireless transmission of signals, the use of radio technology has proven advantageous. Suitable frequency bands include, in particular, the range from 800 to 1000 MHz, preferably 866 MHz to 922 MHz, and sub-bands thereof, such as 866.0 to 866.5 MHz, 868.0 to 868.5 MHz, 868.7 to 869.2 MHz, 905.0 to 926.5 MHz, and / or 921.0 to 922.0 MHz, depending on the application. Thus, the transmitter is preferably a radio transmitter and the receiver preferably a radio receiver, preferably mirrored with corresponding receivers and transmitters in the area of ​​the data processing equipment.Instead of simply placing the data processing unit between the at least one detection unit and the at least one substance delivery unit, the data processing unit can also be coupled to (or directly part of) either a detection unit or a substance delivery unit, so that only a single wireless transmission path is necessary. If the data processing unit is part of a detection unit, it is not necessary to transmit wirelessly from the detection unit to the data processing unit; instead, the data processing unit can directly transmit signals to the receiver at the substance delivery unit via a wireless transmitter.Conversely, the data processing unit may be part of a substance delivery unit, so that only the at least one detection unit needs to send data wirelessly (especially via radio) to the substance delivery unit, where no wireless data traffic is required between the data processing unit and the electrical circuit / valve.

[0038] As an alternative to transmitting data via direct radio signals, data transmission can also take place via a local area network (Wireless Local Area Network, WLAN), using known (and possibly already existing in the building) Bluetooth devices. ® -Coupling devices are used, and the like.

[0039] According to a further preferred embodiment, the at least one detection device comprises at least one of: The invention can be used with a motion detector, a vibration detector, a glass break detector, a door opening detector, or a radio frequency detector, whereby measurements using infrared, microwaves, etc., are possible, either in conjunction with or as a supplement. The invention is generally applicable to detection devices that may already be present in a home alarm system. Existing motion detectors and glass break detectors can simply transmit their signals to the data processing unit, whereby the substance delivery unit must then be present in the building as additional equipment, possibly in conjunction with said data processing unit.

[0040] According to a preferred embodiment of the invention, a substance delivery device comprises a housing sealed against the gas, which includes the storage device, the valve, the electrical circuitry, and the receiver. An outlet leading from the housing, via the valve, opens into a delivery hose. In this way, the storage device can be safely contained within the housing to prevent the optional CS gas from accidentally escaping. The delivery hose allows for virtually any location where the substance is dispensed along with the gas.

[0041] According to a preferred embodiment, the delivery hose is provided for in that at least one section is embedded in a building wall, a window frame with a window and / or a door frame with a door, wherein respective outlet openings in the embedded section allow the gas to be released in front of the building wall, the window and / or the door.

[0042] Interior and / or exterior fogging is possible. By mounting the system on building walls, especially exterior walls, windows, and / or doors, an intruder can be targeted precisely with the substance. Since only small outlet openings are visible to the intruder, the entire system can be installed discreetly. For example, the substance delivery unit with its sealed housing can be located inside the building, while the outlet openings from the delivery hose inserted into the building wall, window frame, and / or door frame can then face outwards.

[0043] According to a further preferred embodiment of the substance delivery device with the housing, the device is portable and can therefore be freely positioned within the building. This makes retrofitting the device particularly easy. In the example with the delivery hose and the respective sections with outlet openings embedded in the building wall, window frame, and / or door frame, retrofitting is very easy, despite the installation within the building.

[0044] In connection with the aforementioned embodiment with the electrical energy storage device, the substance dispensing device is preferably provided with a window in the housing, allowing a view of a charge level indicator on / in the electrical energy storage device. Here, "window" means, while maintaining gas tightness, that a recess has been made in the housing material into which a transparent material (glass, clear plastic) is gas-tightly inserted. With a solid housing, the radio signal intended for the receiver inside the housing can also enter through such a window. Alternatively, the receiver is located outside the housing and connected to components inside the housing via cabling that passes through a small opening.

[0045] The gas dispensing device according to the invention (as an example of a substance dispensing device of the aforementioned device for preventing the continuation of a break-in into or within a building) comprises a housing in which a gas reservoir, in particular a gas cylinder, is housed, wherein the gas in the reservoir is under overpressure, the overpressure being between 3 and 10 bar, preferably more than 4 bar and particularly preferably at most 6 bar. The housing has a base body and a lid that seals against the base body. It also includes a valve at an outlet of the reservoir and an electrical circuit for moving the valve into an open position.A hose is connected downstream of the valve, having at least one outlet. This outlet leads into a delivery hose, the respective outlet openings of which are spatially separated from the storage unit. This spatial separation is achieved by routing the delivery hose through an obstruction and / or by a minimum length of 2 m, preferably 3 m, and more preferably 5 m, up to a first outlet opening. A receiver for wirelessly transmitted signals is located within the housing. This receiver is designed to activate the electrical circuit upon receiving at least predetermined signals, thereby opening the valve so that the gas automatically enters the hose. This gas delivery device, together with the housing, can be constructed as a particularly compact component of the device discussed above, thus facilitating easy retrofitting to provide the complete device.

[0046] According to a preferred embodiment of the gas delivery device, the base body is milled from a solid block of aluminum. This makes the gas delivery device particularly stable and, if necessary, tamper-proof.

[0047] According to a preferred embodiment, as already mentioned above, the gas is, or comprises, 2-chlorobenzylidene malononitrile (CS gas). Also preferably, as already mentioned above, the valve is a solenoid valve, the electrical circuit preferably includes a relay, and the receiver is preferably a radio receiver.

[0048] According to a further preferred embodiment of the gas delivery device, the hose to each outlet includes a pressure relief valve and / or a misting nozzle. Thus, the gas entering the hose from the storage tank under high pressure exits precisely at the hose outlets.

[0049] As mentioned above, a window is preferably provided in a substance dispensing device. In the gas dispensing device according to the invention, a closed viewing window is preferably provided in the lid (as an alternative to the also possible provision in the aluminum block). Alternatively, any opening can be omitted to prevent possible interference and to secure the (magnetic) valve. The (radio) receiver is then ideally arranged outside the hernetically sealed housing and couples signals in via a cable.

[0050] According to a preferred embodiment, an electrical energy storage device is provided for operating the receiver, the electrical circuit, and / or the valve. This device preferably includes a charge level indicator, which is visible through the preferably present viewing window. As already explained, this allows for system self-sufficiency. Even if burglars, for example, sabotage the central power supply, they can still be prevented from continuing the burglary, provided a comparable existing detection / data processing device is equipped with a new gas delivery device and the electrical energy storage device.

[0051] According to a preferred embodiment, the housing is furthermore cuboid in shape and has a dimension in a first direction of between 25 and 35 cm (approximately 30 cm), a dimension in a second direction perpendicular to the first preferably between 20 and 30 cm (approximately 25 cm), and preferably a dimension in a third direction perpendicular to the first and second directions of between 10 and 20 cm (approximately 15 cm). The cuboid housing can thus particularly preferably have dimensions of 30 cm x 25 cm x 15 cm, with variations of a few centimeters (approximately ± 5 cm).

[0052] According to a further preferred embodiment, the gas dispensing device comprises a holder for the storage, preferably a receptacle for the foot area (which may be designed as a retaining ring if a typical bottle with a round cross-section is present), and furthermore, there are retaining arms and / or a clamp for an upper area of ​​the storage.

[0053] The device mentioned at the outset for preventing the continuation of a break-in into or in a building by means of a substance comprising a gas preferably has as a substance delivery device the gas delivery device according to one of the embodiments mentioned above.

[0054] The device according to the invention provides a method, which can be considered an aspect of the invention, for preventing a continuation of a break-in into or in a building by means of a substance comprising a gas, wherein the method comprises: - Detecting unauthorized entry into a private area; - Sending a signal indicating detection to a data processing unit; - Determining by the data processing unit whether and to which unit a signal is issued that is intended to release the substance; - Transmission of the signal to a substance delivery device (in particular the gas delivery device of the type according to the invention, also in preferred embodiments); - Enabling the escape of a gas under overpressure through the substance dispensing device due to the signal from the data processing device, wherein the overpressure is between 3 and 10 bar, preferably more than 4 bar and particularly preferably at most 6 bar, wherein the gas flows into a dispensing hose, the respective outlet openings of which are spatially separated from the substance dispensing device, wherein the spatial separation is given by passing the dispensing hose through an obstacle and / or by a minimum length of the dispensing hose up to a first outlet opening of 2 m, preferably 3 m, further preferably 5 m.

[0055] In this context, it is preferably provided that the release is enabled by switching a valve, that the data processing device uses a machine learning model, and that detection is carried out by means of an intrusion detector, and that the machine learning model additionally uses image data from a camera and / or audio data from a microphone to determine whether the substance delivery device, and if so, which of a plurality of substance delivery devices, should release gas.

[0056] The invention is described in more detail below with reference to the drawing. The drawing shows: Fig. 1 an exploded view of a gas release device according to one aspect of the invention, which can be used in a device according to the invention to prevent the continuation of a burglary, Fig. 2 schematically the gas release device Fig. 1 with associated hose, Fig. 3 the outlet arrangement of the gas delivery device as well as Fig. 4A the inside of a building's exterior wall, in which the gas supply device is made Fig. 1 / 2 is assembled and Fig. 4B the outside of the building's outer wall made of Fig. 4A with gas outlets and detection devices.

[0057] One in Fig. The gas dispensing device 10, shown in exploded view, comprises a base body 12 milled from a block of aluminum and a cover 14 for tightly sealing the base body, for which purpose the seal 15 is used. A holding device 16 for a gas cylinder 18, containing CS gas (2-chlorobenzylidene malononitrile) at an overpressure of between 3 bar and 10 bar, is attached to the base body. The holding device 16 includes a mounting plate 20, on which the support 22 is attached. This support 22 comprises a rod 24 with a receptacle in the form of a ring 26 with a bearing surface 28 and, in its upper region, retaining arms 30a, 30b. The cylinder 18 can be inserted from above between the retaining arms 30a, 30b up to the ring 26 and is held by the bearing surface 28. The holding device 16 can then be pushed into the base body 12 with the cylinder in place.Furthermore, a rail 32, preferably in the form of a DIN rail, is provided on the mounting plate 20 for insertion, as well as a pluggable cable bridge 34.

[0058] The bottle 18 has a valve 36 in the region of its outlet, in a manner known per se. Downstream of the valve 36 is a quick-release coupling 38 with a fixed outlet pipe 40, the outlet pipe being followed by two reducers 42, 44. The pipe 40 with the reducers 42 and 44 and a further elastic section, as described below with reference to Fig. As described in section 2, within the scope of this utility model it is also to be understood as a hose.

[0059] As from Fig. As can be deduced from Figure 1, the housing of the gas delivery device is milled from a solid block of aluminum (forming the base body 12) and sealed with a precisely fitted aluminum cover 14, with a circumferential seal 15 ensuring gas tightness. The remaining wall thickness is nowhere less than 1 cm and preferably not less than 2 cm. The high stability and tamper resistance allow for the permanent and secure housing of all functional units within the enclosure.

[0060] As from Fig. As can be seen in Figure 2, the reduction 44 is followed by a hose section 46, which may be made of elastic, high-pressure resistant plastic material. The hose section 46 has two outlet openings 48 and 50, in the area of ​​which high-pressure valves are provided, in particular, that open as soon as the gas escaping from the bottle 18 when the valve 36 is opened enters the hose 46. The outlet openings do not have to be provided directly in a hose body, but may also be located in branches 52 and 54, for which a [missing information] may be provided in the Fig. 3. The T-piece shown can be provided in the hose.

[0061] From the Fig. Figure 1 further shows that the solenoid valve 36 can be controlled by an electrical circuit in the form of a radio relay 56. Its antenna can optionally be located outside the housing and couple in via a cable routed through an opening in the housing. A battery 58, for example a lithium-ion battery with an integrated battery management system (BMS), is associated with the radio relay 56. The state of charge of the battery can be read on a display 60, which is held in a holder 62, through a viewing window 64 in the area of ​​the cover 14.

[0062] For the exploded view according to Fig. It is to be explained that, as stated above, the holding device 16 can be inserted into the base body 12. It is assumed here that the gas cylinder 18 is arranged in the holder 22. In order for the gas to escape to the outside, the base body 66 has a bore, with the reducer 42 on the inside of the bore and the reducer 44 on the outside of the bore.

[0063] Fig. Figure 4A schematically shows an arrangement for providing a device according to the invention in or on an exterior wall 80 of a building, as seen from the inside. The device 10 is shown here, with the hose 46 belonging to the device 10 being mounted on the exterior wall 80 with the outlets 48 and 50. Furthermore, there is a data processing unit 90.

[0064] Fig.Figure 4B shows the same building exterior wall 80 in an external view. Outlets 48 and 50 are visible. A motion detector 92a, a door opening detector 92b, and a window glass break detector 92c are provided as detection devices on the building exterior wall 80. These detection devices are equipped with transmitters 94a, 94b, and 94c, which transmit wirelessly to the data processing unit 90, which is equipped with a corresponding receiver 96. The data processing unit is then able to determine whether a break-in is actually taking place. Images of the area in front of the building, captured by a camera 92d, can also be recorded, if necessary by an artificial intelligence implemented in the data processing unit 90, which is provided by a machine learning model 97.The data processing device 90 can send signals via a transmitter 98 to the radio relay 56, which then energizes the solenoid valve 36, whereupon this is moved into an open position, whereupon the gas from the bottle 18 exits and enters the elastic hose section 46 via the pipe section 40 of the hose and the reduction 42 and 44, and exits via the high-pressure valves at the openings 48 and 50.

[0065] Fig. 3 shows the integration of the outlets, such as outlet 48, into the building's outer wall 80: This wall has a passage 68 for the outlet nozzle 70, which branches off from the T-piece 52. The outlet nozzle 70 leads into a high-pressure outlet valve 74. This valve can be covered by an open protective housing 76, which protects against damage but allows the gas to escape.

[0066] When CS gas is used, a burglar standing in front of the door or window is prevented from continuing the break-in. Due to eye, respiratory, and skin irritation, the burglar becomes disoriented and unable to act further. The intrusion is thus effectively interrupted. The invention combines a classic defense effect using tear gas with modern security technology (especially IoT security technology, where IoT stands for "Internet of Things") in a robustly constructed housing. The system not only provides an alarm but also active defense. Furthermore, it is possible to trigger an immediate response without relying on external power sources or manual operation.
