Description

[0001] The present invention relates to a device for securing and / or monitoring locking means, in particular locking means of doors and / or windows, preferably emergency exit doors, wherein the device comprises a base element and a movable element which is movably held on the base element between a securing position for securing a locking means against unintentional opening and a release position for opening the locking means.

[0002] Furthermore, the invention relates to an arrangement and a method for securing and / or monitoring locking devices, in particular locking devices of doors and / or windows, preferably emergency exit doors. Finally, the invention relates to a movable component for closing an opening in a building, in particular a door and / or window, preferably an emergency exit door.

[0003] Such devices, which are also known as door monitors, are used to continuously monitor movable components for closing an opening in a building, for example an emergency exit door. The movable components can be doors, windows, in particular emergency exit doors. Such movable components usually have locking devices, for example a door handle, a window lever or an operating rod. For example, the device, specifically the movable element, is attached to a door below a door handle. In its secured position, it then usually rests against the door handle, which is in its closed position. If the door handle needs to be moved down in an emergency, for example, the movable element moves out of its secured position so that the door handle can be moved down.As a result of the movement of the movable element from its locking position towards its release position, an alarm can be triggered, for example in the form of an acoustic and / or optical alarm signal.

[0004] There are various designs of such door guards. One design involves the movable element being pivotally mounted on the base element, allowing it to pivot about a pivot axis between its locking position and its release position. In other words, in this case, the movable element is first moved out of the door handle's range of motion so that the door handle can be moved. Since the direction of movement, specifically the pivoting movement, does not correspond to the direction of movement of the door handle, the movable element must be manually moved out of its locking position before the door handle can be operated.

[0005] There are also embodiments in which the movable element is held on the base element so that it can be moved translationally between an upper securing position and a lower release position. In this case, the direction of movement of the movable element corresponds to the direction of movement of the door handle, so that the movement of the door handle also indirectly moves the movable element from its securing position toward its release position. Since separate manual actuation of the movable element is not required, but rather the movement results inevitably from the movement of the door handle, this embodiment is also referred to as a one-hand door guard. Such a door guard is previously known, for example, from DE 20 2016 103 349 U1.

[0006] Such devices have generally proven effective. However, especially in larger building complexes with a large number of locking devices and, accordingly, a large number of devices for securing and / or monitoring these locking devices, there is a need to monitor the status of the individual devices.

[0007] Against this background, the object of the present invention is to provide an alternative device for securing and / or monitoring closure elements, an arrangement and a method, as well as a movable component for closing an opening in a building. Preferably, the device should allow monitoring of its condition.

[0008] This object is achieved in a device of the type mentioned at the outset in that it has a communication interface which is designed to send status data relating to the status of the device, in particular to a receiver device.

[0009] The invention is therefore based on the fundamental idea that the device can transmit its status via a communication interface, in particular to a receiver device, so that, for example, the status of a plurality of devices and thus of the locking means interacting with them, for example of emergency exit doors, can be centrally monitored via this receiver device. In other words, the device is designed to transmit information about its status so that this can be monitored by a receiver device. The locking means can be, for example, door handles or window levers or operating levers for opening doors, in particular emergency exit doors.Typically, the closure means are characterized in that they are normally located in a closed position, in which the respective movable element is kept closed to close an opening in a building, and can be moved from this closed position into an open position, in which the movable element can be opened. In other words, in its secured position, the movable element engages in the movement range of the closure means, whereas in its release position it is moved out of the movement range, so that the closure means can be moved or actuated. Preferably, the closure means and / or receiver device are not part of the device, but interact with it during the intended use of the device.

[0010] The communication interface can be configured to wirelessly transmit status data relating to the state of the device to a receiver device. In principle, the communication interface can be configured to transmit status data via WLAN or Bluetooth or another common wireless system.

[0011] In a further embodiment, the communication interface can be designed as a mobile communications interface. This allows an existing mobile network, which is available virtually everywhere, to be used to transmit the status data. This eliminates the need to install a separate local network or install complex cabling in the building in question.

[0012] Specifically, the communication interface can be configured to send status data to a receiving device using the Narrow Band Internet of Things (NB-IoT) protocol. The NB-IoT protocol, also known as LTE Cat NB1, is a wireless technology that can be seamlessly integrated into existing mobile networks. This protocol is preferably characterized by the fact that only low energy consumption is required to transmit data while at the same time achieving good penetration, especially in buildings. It has been shown that, with the use of appropriate batteries, operating periods of up to ten years are possible. Furthermore, components such as modems are available at low cost. The NB-IoT protocol can also be encrypted.

[0013] The NB-loT protocol is preferably characterized by being based on the LTE standard, but with a bandwidth limited to a single narrowband of 200 kHz. It can use orthogonal frequency division multiplexing (OFDM).

[0014] The status data can include information on the position of the movable element and / or on the triggering of an alarm and / or identification data of the device and / or information on the positioning of the device in a building. In other words, the status data can indicate whether the movable element is in its release position or in its secure position. Furthermore, it can be transmitted whether an alarm has just been triggered, for example if the movable element is moved out of its secure position. For unique identification, identification data relating to the device can be provided, as well as information on the positioning of the device in a building. This enables unique identification and assignment of the individual devices, particularly in larger building complexes.

[0015] The device can further contain an energy storage device. This can be designed as a battery or an accumulator. For example, it can be a lithium-ion accumulator. The energy storage device is preferably rechargeable. The status data can include information on the charge level of the energy storage device. This embodiment is based on the idea of ​​transmitting this to a receiver device if the charge level of the energy storage device is too low, in order to be able to replace or recharge the energy storage device in a timely manner. In this way, it can be ensured that an alarm is always triggered when the movable element is moved out of its secured position. A situation in which an emergency exit door is opened without an alarm being triggered due to an empty energy storage device can thus be avoided. It can be provided that the device is not connected or connectable to the power grid.

[0016] The device preferably includes a sensor configured to detect whether the movable element is in its secured position or outside its secured position. The device may include a computer connected to the communication interface and configured to process the data provided by the sensor and transmit instructions to the communication interface. The computer may also be integrated into the communication interface.

[0017] According to a preferred embodiment, the device comprises an acoustic and / or optical signal generator configured to emit an acoustic and / or optical alarm signal. An acoustic signal generator may comprise or consist of a loudspeaker. An optical signal generator may comprise or consist of a light source, which, for example, flashes when an alarm signal is emitted.

[0018] The device is preferably designed to emit an acoustic and / or visual alarm signal when the movable element is moved from its secured position toward its release position. In other words, a corresponding alarm signal can be emitted when the locking means is actuated and, in conjunction with this, the movable element of the device is moved from its secured position. In this way, it can be signaled that an emergency has occurred, for example, when an emergency exit door is opened.

[0019] The communication interface can be configured to receive commands, in particular from a receiver device. This configuration is based on the idea that the device not only transmits status data to a receiver device, but can also receive instructions from a receiver device. These commands can be transmitted to the device in the same way as the status data is sent from the communication interface. Specifically, the device can be configured to output an acoustic and / or visual alarm signal upon a corresponding command from a receiver device.In this case, the device can emit an alarm signal not only when the movable element of this device is moved from its securing position towards its release position, but also on the instruction of a receiving device, for example when there is a fire alarm and the entire building has to be evacuated.

[0020] In a further embodiment, the device can comprise a pre-alarm sensor element for detecting a movement, in particular an opening movement of the locking means, preferably when the movable element is in its secured position. In other words, the device can be suitable for detecting an intended opening movement of the locking means, for example a door handle, before the locking means is fully actuated and / or brought into an open position. Specifically, the pre-alarm sensor element can be designed as a button on an upper side of the movable element. This means that such a button is first actuated before the movable element is moved out of its secured position. When the button is actuated, an intended opening of the locking means can thus be detected, even if the movable element is still in its secured position.The device can be configured to emit an acoustic and / or visual pre-alarm when the pre-alarm sensor element is actuated. The pre-alarm can be different from an alarm signal that is emitted when the movable element is moved out of its secured position. In this way, a user can be warned that they are, for example, at an emergency exit door and that an alarm will be triggered if they continue to move or actuate the locking means.

[0021] Preferably, the communication interface can be designed to send information about a pre-alarm, in particular to a receiver device, when the pre-alarm sensor element detects an opening movement of the closure means.

[0022] According to a preferred embodiment of the invention, the movable element can be pivotally mounted on the base element, so that the movable element can be pivoted about a pivot axis between its locking position and its release position. Typically, in this case, the movable element must be manually pivoted before the locking means, for example, a door handle, can be moved into its opening position.

[0023] Alternatively, the movable element can be held on the base element so that it can be moved translationally between, in particular, an upper securing position and a particularly lower release position. In this case, gravity can preferably be used to move the movable element from an upper securing position into a lower release position, for example by moving the locking means in the direction of its open position. The device is preferably designed such that when moving out of the securing position, a resistance must first be overcome before the movable element moves towards the release position. With such translational mobility, one can speak of a one-hand door guard, i.e. the movement of the locking means, for example a door handle, is sufficient to move the movable element out of its securing position.A separate manual movement of the movable element out of its locking position, which would require the use of the other hand, for example, is not necessary, unlike in the case of a pivoting movable element.

[0024] The movable element can have a cuboidal basic shape. In particular, it can be open towards the base element, so that together with the base element it forms a receiving space for various components, for example, the communication interface, an energy storage device, sensor means, etc. These components can be partially or completely attached to the movable element or to the base element. The movable element preferably covers the base element and / or is flush with it when in its secured position.

[0025] Furthermore, a mechanism can be provided that holds the movable element in its locking position. The mechanism can be designed such that, when the movable element moves out of its locking position, a resistance must first be overcome before the movable element moves out of its locking position.

[0026] In a further embodiment, the device can have resetting means for terminating an alarm. In particular, these resetting means can comprise a preferably manually operable lock. The lock can have or consist of a locking cylinder. This embodiment is based on the idea of ​​terminating the alarm signal after the movable element has been moved out of the secure position and the alarm signal has been triggered, for example by using a manually operable lock. A specific key may be required for this, so that only certain people can operate the lock. The device can also be designed such that the movable element can be moved back from its release position to its secure position only by actuating the resetting means, in particular the lock. Resetting via a chip card is also conceivable.Alternatively or additionally, the device can also be designed in such a way that a receiver device sends a corresponding signal via the communication interface of the device, by which the alarm is terminated.

[0027] The base element of the device can comprise fastening means for attachment to a movable structural element for closing an opening in a building, for example a door and / or a window, preferably an emergency exit door. For example, the base element can have corresponding bores to which the device can be screwed. Furthermore, an adapter plate can be provided, by means of which the base element can be attached, in particular screwed, to a door or window frame. Specifically, the base element can be attached to the adapter plate and the adapter plate can in turn be attached, in particular screwed, to a door or window frame. In a further embodiment, the base element can be at least substantially plate-shaped.

[0028] The object underlying the invention is further achieved by an arrangement for securing and / or monitoring closure means comprising at least one device for securing and / or monitoring closure means, in particular as described above, and at least one, in particular exactly one, receiver device to which the communication interface(s) of at least one, in particular each, or of the at least one device can transmit status data relating to the status of the respective device. The arrangement preferably contains a plurality of devices which are or can be attached in particular to various movable structural elements for closing an opening in a building and preferably interact with the closure means of these structural elements. The respective devices can be designed identically or differently. The devices are preferably designed as described above.

[0029] The arrangement may comprise a central receiver device, which in particular comprises a central computer unit or a central server or is connected to such a central computer unit or server. For example, such a central receiver device may be housed in a building complex and thus communicate directly with one or more devices distributed within the building complex.

[0030] Alternatively, the arrangement can comprise a platform, in particular a cloud-based platform, which contains at least one receiver device. A cloud-based platform, which can also be referred to as a cloud platform, is preferably not set up locally at a fixed location, but is arranged distributed via the Internet across various computers, servers, or the like. This can ensure, for example, that, unlike a central receiver device in the building, status data is transmitted to another location, in particular wirelessly, preferably via mobile communications, and thus reliable monitoring of the status of the devices is possible even in the event of a fire or natural disaster. In other words, such a cloud-based platform is preferably formed by a computer network, wherein the various computer units are connected to one another, for example, via the Internet.Preferably, the receiver device is designed to communicate wirelessly with the at least one, in particular each, device, specifically to receive status data from it and / or to send commands to it.

[0031] In a further embodiment, the receiver device preferably contains a mobile radio module which is particularly designed to communicate with at least one, in particular each, or with the at least one device according to the NB-loT protocol, specifically to receive status data from it and / or to send commands to it.

[0032] The platform, in particular a cloud-based one, or the central receiving device can provide or include human-machine interfaces, for example, by allowing access to the status data via a web browser. The platform or the receiving device can also be configured to provide information relating to the device(s) via mobile devices, such as smartphones or tablets, or to transmit messages to such devices, for example via mobile communications.

[0033] The arrangement may comprise additional components, which are arranged, for example, in a building and which are configured to transmit data concerning their status to the receiver device. The additional components may be motion detectors, smoke detectors, emergency lights, and / or escape sign lights. These additional components preferably have a communication interface configured to communicate with the receiver device in the same manner as described in connection with the device according to the invention, i.e., to transmit status data and / or receive commands.

[0034] Furthermore, the arrangement, in particular the receiver device or the particularly cloud-based platform, can comprise a computer unit or be connected to such a unit. The computer unit can be configured to process and / or monitor status data received from the at least one device and, depending on the history of the status data, to transmit messages about the status, for example, to mobile devices or to send commands to the at least one device.

[0035] The object mentioned above is further achieved by a method for securing and / or monitoring locking devices, in particular locking devices for doors and / or windows, preferably emergency exit doors. An arrangement as described above can be used here. It is provided that the communication interface transmits status data relating to at least one device, in particular each device, or to the at least one device, to a receiver device. The status data can be transmitted to the receiver device at regular intervals. It is also conceivable that, in particular, certain status data are only transmitted when a change in the status occurs. This can be the case, for example, when the movable element is moved from its secured position to its released position.

[0036] Preferably, the communication interface(s) of at least one, in particular each, device or the at least one device transmits status data wirelessly, in particular via mobile radio, to a receiving device. In a further embodiment, the communication interface of at least one, in particular each, device or the at least one device can transmit the status data to the receiving device according to the NB-iOT protocol.

[0037] The status data may include data on the position of the movable element, on triggering an alarm, identification data and data on the location of the at least one device in a building.

[0038] At least one, in particular each device or the at least one device can contain an energy storage device and the information on the charge state of the energy storage device can be transmitted to a receiving device.

[0039] In addition, at least one, in particular each device or the at least one device if it contains a pre-alarm sensor element, can transmit a pre-alarm to the receiver device via its (respective) communication interface if the pre-alarm sensor element detects an opening movement of the closure means.

[0040] If the arrangement contains additional components, these can also send data regarding their status to the receiving device. The central receiving device or the platform can also monitor and process this data.

[0041] In particular, if the arrangement comprises a cloud-based platform containing at least one receiver device, the platform can send commands via the (respective) communication interface to at least one, in particular each, device or to the at least one device. It can be provided that the platform sends a command to one or more devices to trigger a visual and / or acoustic alarm signal at the respective device. This can occur, for example, if a break-in into a building is detected, for example, by a motion detector or a door sensor. In this case, the devices can function as alarm devices.

[0042] In a further embodiment, the central receiving device or the in particular cloud-based platform can send information about the status of at least one, in particular each device or the at least one device to a mobile device, in particular to a smartphone or a tablet, or to a human-machine interface, in particular a PC, or to a corresponding interface, in particular a web browser. The use of an app on a mobile device or on a stationary computer is also conceivable in order to access the status data. Accordingly, the platform or a central receiving device can be designed to send such information. For this purpose, the central receiving device or the in particular cloud-based platform can have a computer unit which processes and monitors the status data transmitted by the at least one device.The computing unit can also process data transmitted by other components. Specifically, the cloud-based platform or the central receiving device can have a corresponding interface, particularly a mobile communications interface.

[0043] The idea behind this design is that the devices not only transmit information about their status, but that an operator / user / provider of such an arrangement is also informed of problems by means of corresponding messages. For example, the operator can be informed early on if the charge level of an energy storage device in a device reaches a critical value. This ensures that the energy storage device is replaced or recharged in a timely manner. It is also possible for an operator to be informed via a corresponding message if the movable element in a device moves out of its secured position and an alarm is triggered. This not only makes it possible to detect accidental or intentional alarm triggering, but also to determine whether a break-in into a building is taking place.

[0044] In a further embodiment of the method according to the invention, the central receiving device or the particularly cloud-based platform can forward information about the status of at least one, in particular each, device or the at least one device, particularly in an emergency situation, to rescue personnel, for example, to provide information about used emergency exits. Especially in larger building complexes, rescue personnel such as the fire department or paramedics can be directed directly to the locations where emergency exits have been used. This way, valuable time can be saved during rescue activities and access to injured persons, for example, can be accelerated.

[0045] The in particular cloud-based platform or the central receiving device can further send commands to the communication interface(s) of at least one, in particular each, device or the at least one device, for example to trigger and / or mute an alarm, in particular an optical and / or acoustic alarm signal.

[0046] The central receiving device or, in particular, the cloud-based platform can record and / or save the status data transmitted by the respective device. This allows, for example, the areas in larger building complexes where problems regularly occur to be identified. It is then possible, for example, to implement increased video surveillance in these priority areas. In other words, the status data can be evaluated accordingly by recording and / or saving it.

[0047] Based on the status data transmitted by the devices, the central receiving device or the cloud-based platform in particular can send messages to human-machine interfaces, in particular to mobile devices, preferably tablets or smartphones.

[0048] The object underlying the invention is further achieved by a movable component for closing an opening in a building, in particular a door and / or a window, preferably an emergency exit door, with a locking means, in particular a door handle or a window lever, wherein the component is provided with a device as described above. The locking means can be, for example, a pivotable door handle or a window lever or an operating lever and / or can be movable, in particular pivotable, between a closed position and an open position. A door handle can have a substantially horizontal orientation in a closed position, whereas the door handle can be inclined downwards from the pivot axis in the open position.

[0049] The device can be attached to the movable component such that the closure means rests directly against the movable element, in particular against a pre-alarm sensor element, when the movable element is in its secured position and the closure means is in its closed position. In this case, movement of the closure means from its closed position can directly trigger a pre-alarm.

[0050] Preferably, the device is attached to the movable component in such a way that the movable element in its securing position prevents or impairs a movement of the closure means, and that the movable element in its release position is moved out of the movement range of the closure means.

[0051] For further details of the invention, reference is made to the dependent claims and the embodiment described below with reference to the drawing. The drawing shows: Figure 1 shows a device for securing and monitoring closure means according to the present invention in a perspective view; Figure 2 shows the device from Figure 1 in a front view; Figure 3 the device from Figure 1 in a side view; and Figure 4 shows an arrangement according to the present invention with the device from Figure 1 in a schematic representation.

[0052] The Figures 1 to 3 show a device 1 according to the invention for securing and monitoring locking devices, for example door handles, of emergency exit doors. This device comprises a Figures 1 to 3non-directly visible base element 2, which has fastening means, for example in the form of fastening holes 3, for example, to be attached to an emergency exit door. The base element 2 is shown hatched in Figure 3. The fastening holes 3 are also shown in Figure 3 indicated by dotted lines.

[0053] The device 1 further comprises a movable element 4, which has a cuboidal basic shape. The movable element 4 is mounted on the base element 2 so that it can be moved translationally between an upper locking position, as shown in the figures, for securing a closure means against unintentional opening, and a lower release position for opening the closure means.

[0054] The front of the movable element 4 is provided with a pictogram 5 for an emergency exit door and an arrow 6. The arrow 6 indicates the direction in which the movable element 4 is to be moved when it is to be brought into its release position.

[0055] On its upper side, the movable element 4 carries a pre-alarm sensor element in the form of a button 7, which is designed to detect an opening movement of the locking means when the movable element 4 is in its secured position. In other words, it detects when the button 7 is pressed slightly downward, which happens, for example, when the door handle of an emergency exit door is moved slightly downward.

[0056] The device 1 further includes sensor means designed and suitable for detecting whether the device is in its securing position or outside of its securing position or in its release position. The sensor means are not shown in the figures. Furthermore, the device 1 includes an energy storage device 8, which is designed, for example, as a battery or rechargeable accumulator and is arranged in the Figure 3 is shown schematically.

[0057] In addition, the device 1 contains a communication interface 9, which is designed as a mobile radio interface. The communication interface 9 is shown schematically in the Figure 3 and in the Figure 4 and is designed to send status data relating to the status of the device 1 to a receiver device according to the Narrow Band Internet of Things (NB-loT) protocol.

[0058] The device 1 can be attached to an emergency exit door in such a way that the door handle of the emergency exit door rests directly on the button 7 when the door handle is in its closed position and the movable element 4 is in its secured position. In this case, a slight downward movement of the door handle causes the button 7 to be actuated and a pre-alarm to be detected by the pre-alarm sensor element. An acoustic output device 10 in the form of a loudspeaker, which is shown only schematically in Figure 3In this case, the door handle, as shown, emits a signal so that the person operating the door handle recognizes that an alarm is about to be triggered. If the person continues to operate the door handle downward, a certain resistance is overcome, which holds the movable element 4 in its upper locking position, so that the movable element 4 moves downward into its release position under gravity. In this case, the acoustic output device 10 emits an alarm signal.

[0059] If the alarm needs to be silenced or the movable element 4 needs to be returned to its secure position, a manually operable lock 11 can be used with a corresponding key. By turning the locking cylinder of the lock 11, the alarm can be silenced or acknowledged, and the movable element 4 can be returned to its release position.

[0060] Alternatively, the alarm can also be silenced by a corresponding command from the receiver device. For this purpose, the communication interface 9 is designed to receive commands from a receiver device.

[0061] In the Figure 4 Finally, an arrangement according to the invention is shown. This comprises a device 1 as described above and a cloud-based platform 12, which is schematically depicted as a computer network. The cloud-based platform 12 contains a receiver device 13. The communication interface 9 of the device 1 is designed to transmit status data relating to the status of the device 1 to the receiver device 13 of the cloud-based platform 12 at regular intervals. Specifically, this occurs via mobile radio according to the NB-IoT protocol.

[0062] The transmitted status data includes information on the position of the movable element 4, on triggering an alarm, identification data concerning the device 1, and information on the positioning of the device 1 in a building. Furthermore, the status data includes information on the charge level of the energy storage device 8.

[0063] For example, if the door handle of the emergency exit door to which device 1 is attached is moved downwards, the pre-alarm sensor element (button 7) first detects the opening movement of the door handle. The acoustic output device 10 then emits a pre-alarm, informing the person operating the door handle that the emergency exit alarm in question is secured. If the door handle is no longer operated but is released again, the pre-alarm ceases and the movable element 4 remains in its upper secured position. If the person in question decides to operate the door handle further downwards, the movable element 4 is moved against resistance from its upper secured position and falls into its lower released position due to gravity.

[0064] The sensor means detect this, so that an alarm signal is emitted via the acoustic output device 10. At the same time, the communication interface 9 transmits this change in state to the receiver device 13 of the cloud-based platform 12. The cloud-based platform 12 can then send a corresponding message to a mobile device 14, for example, a smartphone. In this way, information can be forwarded to rescue personnel, for example, that the emergency exit in which the device 1 is mounted has been used.

[0065] Furthermore, it is possible to send a message to the cloud-based platform 12 by corresponding operation on the mobile terminal 14 in order to send a message to the communication interface 9 of the device 1 via the receiver device 13 and, for example, to mute the alarm.

[0066] It is also possible, in an arrangement containing multiple devices 1, which are distributed, in particular, throughout a building complex, to practically control them via the cloud-based platform 12. For example, if a break-in is detected, each device 1 can be controlled, and an alarm signal can be issued regardless of the position of the movable element 4. List of reference symbols
