[0001] “Safety apparatus for doors”

[0002] Description

[0003] Field of the invention

[0004] The invention relates to the field of safety systems for doors. More specifically, the present invention is aimed at providing a safety system for opening a door capable of monitoring the surrounding environment and any emergency situations, consequently unlocking or locking the door.

[0005] Prior art

[0006] To ensure safe access to private and public facilities and even to restricted areas of public facilities, technology is increasingly relied upon to identify the people attempting to gain access, to allow easier access for people with disabilities, and to send emergency warnings. There are several solutions currently offered by industrial patents to solve problems of various kinds related to safety efficiency and the implementation of monitoring and verification technologies on doors.

[0007] An example is the subject matter of patent CN102081813A of GUOYUAN XU which provides a smart face identification safety door comprising a DSP (digital signal processor) controller, a laser shooting module assembly, a display screen, a keyboard, an electronic lock, a shock sensor, an alarm speaker, a shooting and recording apparatus, a synchronous dynamic random access memory (SDRAM), a flash memory, a clock chip with backup cells, a buzzer, a universal serial bus (USB) interface chip, a network interface chip, a storage hard disk, a power circuit and a door body. By employing automatic alarm projects, automatic shooting and recording, and image and sound data storage, the invention moves from physical feature identification to biological feature identification and from passive burglar alarm to active burglar alarm.

[0008] Another example is the invention of CN106522792A by ZHOU WEI. The invention describes an automatic-opening fire door suitable for opening in an emergency, allowing the evacuation of a building / room. The door opening occurs by means of a magnetic unlocking system that activates equipment that uses pressurized gas to separate the door from the wall and push it to the ground in the event of a fire.

[0009] Another example is the patent of CN215644296U of ZHENG ZHIYING. The patent describes a magnetic switch for smart doors, which comprises a rectangular seat, a fixed magnetic block and a movable magnetic block, the fixed magnetic block is arranged in the rectangular seat, the movable magnetic block is placed on the door leaf. A safety structure is arranged in a rectangular seat and is connected to the movable magnetic block. The safety structure comprises an adjustment part and a limitation part, the adjustment part is arranged on the surface of the seat, the limitation part is arranged between the seat and the movable magnetic block. The safety structure improves the opening, possibly limiting the possibility thereof and providing an additional element of resistance.

[0010] The inventions reported so far, by way of non-exhaustive example, are representative of the inventive-technological framework available to date.

[0011] Technical problems related to the inventions currently available on the market include the clear identification, even in conditions of poor visibility (for example due to smoke from a fire), of the escape routes, as well as knowing the blocked / unblocked status of a door due to the emergency situation (for example, a door blocked by debris fallen following a seismic event).

[0012] There is also a need to create a safety device for a door that can solve technical problems of accessibility for disabled people, that can monitor not only the surrounding environment but also parameters indicative of emergency conditions and that can consequently combine the information acquired through specific acquisition devices / sensors to respond effectively in emergency conditions. In the following text, emergency conditions are understood as conditions such as fires of any nature and cause, seismic events and partial structural and / or non-structural collapses and / or deformations.

[0013] The object of the present invention is to provide a solution to the aforementioned technical problems by providing a safety system for a door that ensures greater safety and easier accessibility for users.

[0057] FIG. 2 shows an embodiment of the present invention in which the elements of said apparatus just described are arranged on a leaf of a door 1, on its frame and in its vicinity.

[0058] A presence signal of a living body is produced by said signaling apparatus 105 and / or said projectors 110 when said presence sensors 112 and / or said movement sensors 104 detect the presence / movement of a living body in the spaces in front of the door 1.

[0059] In other preferred embodiments of the present invention such as that shown in FIG. 1, said locking device 101, said magnetic sensor 102, said inertial sensor 103, said movement sensor 104, said presence sensor 112, said signaling apparatus 105, said cameras 106, said temperature sensor 107, said smoke detectors 108 and carbon dioxide detectors 109, said projector 110, said PLC 120, said wireless communication unit 121 and / or said button 140 are comprised in a single device 200. Said signaling apparatus 105 comprised in the device 200 comprises emergency lights and a buzzer.

[0060] It is to be understood that the device 200 comprises therein, in a single case (preferably made of plastic and / or metal material), the locking device 101 and / or the magnetic sensor 102 and / or the inertial sensor 103 and / or the movement sensor 104 and / or the presence sensor 112 and / or the signaling apparatus 105 and / or the cameras 106 and / or the temperature sensor 107 and / or the smoke detectors 108 and / or the carbon dioxide detectors 109 and / or the projector 110 and / or the PLC 120 and / or the wireless communication unit 121 and / or the button 140. This implies the existence of embodiments of the invention in which all the cited elements are inside said device 200, as shown in FIG. 1 and embodiments in which only some of the cited elements are therein. Said device 200 comprises at least a light suitable for illuminating when said presence sensor 112 detects the presence of a living body; said cameras 106 suitable for being optical and / or thermal and provided with microphones; said device 200 comprising one or more loudspeakers. In some embodiments of the present invention, said camera microphones are used to acquire audio which is then used to perform speech recognition as will be described below.

[0061] With specific reference to FIG. 1, it shows an embodiment of the device 200 which can be mounted at the bottom, as shown, or also at the top, as well as horizontally or vertically on said leaf of the door 1. The positioning shown in FIG. 1 is such as to allow even nonambulatory people, for example in wheelchairs, to easily reach the button 140 and press it.

[0062] Components that are mounted directly on the door 1 (as well as the device 200) can be mounted, by way of non-limiting or binding example, by means of metal anchoring brackets. The components can be mounted in a substantially horizontal or substantially vertical position and the bracket allows a mounting thereof on both doors with uneven jambs and doors with straight jambs.

[0063] The dashed lines shown in FIG. 2 are to be considered representative of electronic connections between the components.

[0064] In some embodiments of the present invention, said PLC 120 is adapted to receive a signal from said temperature sensors 107 and said detectors 108, 109 relating to the presence of a fire and / or smoke, on the side of a first side of the door 1. Said PLC 120 is suitable for sending an input to said projectors 110 to project on a second side of the door 1 a graphic and / or textual signal relating to the presence of said fire and / or smoke on said first side. Here, the term “project on a second side of the door 1” means that the projectors 110 project images and / or text messages onto the floor, wall and / or leaf on the side of said second side of door 1. Said PLC 120 being suitable for further sending an input to said signaling apparatus 105 to produce a visual and / or acoustic signal relating to the presence of said fire and / or smoke.

[0065] In some embodiments of the present invention, said PLC 120 acquires the data from the shots of said cameras 106 and sends them to said projectors 110. Said projectors 110 are suitable for projecting, from a first side of the door 1, the shots of said cameras 106 taken on a second side of the door 1. Said proj ectors 110 are suitable for proj ecting said shots when said inertial sensor 103 detects the presence of a person from said second side who knocks or is trying to open said door 1 and / or when said movement sensors 104 detect the presence of a person from said second side for a time that is defined via said web portal and / or application 130 and / or when a specific command to project the shots is sent via said web portal and / or application 130. The “time defined” via the web portal and / or application 130 is a time that can preferably be expressed in seconds or minutes, and is for example equal to 2 minutes. Preferably, the PLC 120 associates the recording of a vibration (recorded by the inertial sensor 103) due to someone knocking on door 1 with the start of the counting of said defined time during which the person remains in front of the door 1. Thereby, not only can people on one side see if someone on the other side is trying to gain access without authorization, but it is also possible for rescue teams who cannot open blocked doors (for example blocked on the other side by debris that has fallen in front of the door) to have a shot directly projected onto the door to communicate with people inside and / or to see if the door is clear to try to break it down during an emergency operation.

[0066] In some embodiments of the present invention said PLC 120 is suitable for receiving a signal from said temperature sensors 107 relating to the temperature of a handle and / or a surface of the leaf of the door 1. When one or more of said temperatures exceeds a threshold value defined via said web portal and / or application 130, said signaling apparatus 105 and said projectors 110 receive input from said PLC 120 to send visual and / or acoustic signals and to project images and / or text warnings relating to the high temperature of said components of the door 1. By way of non-limiting or binding example, said threshold value is defined as 51 °C (via the web portal and / or application 130), it is in fact known that contact with a surface at a temperature higher than 51 °C for more than 2 minutes causes first degree burns. By way of non-limiting or binding example, a second threshold value can be defined as equal to 60°C, it is in fact known that contact for more than 1 second with a surface at temperatures higher than or equal to 60°C causes first degree bums. For the two threshold values, the signaling device 105 and the projectors 110 can provide different signals / warnings. For example, the projectors 110 can project onto the surface of the door above the handle an image relating to the prohibition of touching the handle and also a warning which can include the following example wording: “Warning: handle temperature equal to 62°C” where 62°C can be the temperature detected by the temperature sensors 107 on the surface of the handle and which, in the warning projected by the projectors 110, can be updated in real time.

[0067] In other embodiments of the present invention, such as that shown in FIG. 3, the apparatus 100 further comprises one or more accelerometers 150 distant from the gate 1 suitable for detecting the occurrence of a seismic event. “Distant” from the door 1 means that the accelerometer 150 must preferably be mounted at a distance greater than 1 meter from the door 1 so as not to be affected by vibrations induced by opening / closing the door 1, nor by vibrations induced by attempts to break into / break down the door 1. Thereby, the presence of the accelerometer 150 allows to immediately and unequivocally distinguish a seismic event from a burglary / breaking down of the door 1. Said accelerometer 150 is connected to said PLC 120. Said PLC 120 is suitable for comparing the data acquired by said accelerometer 150 and said inertial sensor 103. Said PLC 120 is suitable for detecting the presence of a seismic event and carrying out an emergency operation when the data acquired by said accelerometer 150 and said inertial sensor 103 are both indicative of vibrations which can therefore be traced back to a seismic event; said emergency operation being the sending of a signal via said signaling apparatus 105, said projectors 110 and / or said web portal and application 130, the automatic unlocking of said locking device 101 and / or the release of the hinges of the door 1 operated by a special expulsion apparatus. Said PLC 120 is suitable for detecting the presence of an attempted break-in / breaking down of the door 1 and of sending an intrusion alert signal via said signaling apparatus 105, said projectors 110 and / or said web portal and / or application 130 when said accelerometer 150 detects an absence of structural / ground vibrations and said inertial sensor 103 detects vibrations on the door 1.

[0068] With reference to FIG. 4, it shows a block diagram representative of the connections between said PLC 120 and other components of the system 100.

[0069] Specifically, FIG. 4 shows how said PLC 120 can be connected to a power supply network 30 (generally an AC / DC power supply) and how the button 140 can act directly on the connection between the said PLC 120 and network 30. FIG. 4 also shows the presence of a buffer battery 21 and a charging circuit. The PLC 120 is shown in FIG. 4 as further connected to an emergency LED light 5, to an energy consumption control sensor 12, to an interface board 14 with external devices, to a voice activation sensor 13, in addition to the components already mentioned and shown in FIGS. 1 and 2.

[0070] The energy consumption control sensor 12 checks the electricity consumption and also checks the presence of power supply, the interface board 14 allows external devices to be connected to the PLC 120. An example of an external device connection is the one operated with a proximity sensor as shown in FIG. 5. In other embodiments of the present invention such as that shown in FIG. 5, in fact, the apparatus 100 comprises one or more proximity sensors 111 suitable for triggering a rapid action, defined via a web portal and / or application 130, when they detect a proximity sensor 111' of a user. Said rapid action, in some preferred forms of the present invention is defined through the web portal and / or application 130 and can be the unlocking of said locking device 101 and / or be the activation of a projection operated with said projectors 110 of one or more data processed by the PLC 120.

[0071] In various embodiments of the present invention, said proximity sensor 111 can use RFID, NFC, Bluetooth and / or other wireless detection technology.

[0072] Specifically, FIG. 5 shows a user (a firefighter) using his own proximity sensor 111' (an NFC chip on his smartphone) to unlock, via the proximity sensor 111, said locking device 101.

[0073] Lastly, the voice activation sensor 13 is a sensor which is part of one or more microphones that the apparatus 100 comprises. In fact, the apparatus 100 in other embodiments of the present invention, such as that shown in FIG. 1 and 4, comprises one or more microphones and loudspeakers suitable for allowing the recording and reproduction of acoustic signals and / or audio recordings. Said microphones are suitable for acquiring an audio recording. The recordings acquired by said microphones are analyzed by speech analysis and recognition software; said speech analysis and recognition software are suitable for translating an audio recording into a command for said PLC 120. Said command is executed by said PLC 120 when said speech analysis and recognition software recognizes the vocal timbre of a user registered in the web portal and / or application 130 and / or when said image recognition software, using facial recognition algorithms, recognizes the face of said user through the shots of said cameras 106. In some embodiments of the invention, said microphones can be comprised in said cameras 106. All the connections between the components shown in FIG. 4 are to be considered “two-way,” thus allowing communication to and from the PLC 120.

[0074] In some embodiments of the present invention, the apparatus 100 further comprises said expulsion apparatus suitable for expelling at least a leaf of said door 1 by releasing the hinges thereof. The “release” of said hinges is carried out, in various embodiments of the present invention, with mechanical devices that lower and retract the lower part of the hinges inside the profile of the frame of the door 1. In other embodiments of the invention, the “release” is operated with mechanical devices that lift and retract the upper part of the hinges inside the door profile. In some embodiments, the mechanical devices that operate the movement of the hinges are devices governed by gears and other known means for producing movement, connected to electric motors, pneumatic devices and / or other moving members. It is believed that means are known to the person skilled in the art for producing a movement of mechanical parts and these will therefore not be described in detail. Said expulsion apparatus is connected to said PLC 120. Said PLC 120 is suitable for sending an input to the expulsion apparatus to release said hinges when said movement sensors 104 and / or said cameras 106 detect the absence of people in the spaces in front of door 1. Said PLC 120 being suitable for sending inputs to said projectors 110 to project a warning to move away from the door 1, of imminent release of the hinges and / or of the leaf of the door 1 when said movement sensors 104 and / or said cameras 106 detect the presence of people in the spaces in front of the door 1. Said PLC 120 sends a further input to said signaling apparatus 105 to signal said warning to move away and / or of release.

[0075] In other embodiments of the present invention, such as that shown in FIG. 6, said image recognition software comprises artificial intelligence algorithms for processing the images acquired by said cameras 106. Said PLC 120 is suitable for receiving a signal from said image recognition software regarding structural / non-structural debris blocking the door 1 from a first side. Said PLC 120 is suitable for sending an input to said projectors 110 to project, on a second side of the door 1, a graphic and / or textual signal relating to the presence of debris on said first side and that the door 1 is blocked and cannot be opened. This signaling is shown in FIG. 6 as a large “X” which is preferably red, which is projected onto both the leaf of the door 1 and the floor in front of the door 1. FIG. 6 shows how even in the presence of dust / smoke, at least one of the projections remains immediately visible even from a distance. Said PLC 120 is suitable for further sending an input to said signaling apparatus 105 to produce a visual and / or acoustic signal relating to the presence of debris blocking the door 1. “Debris” is intended as parts of structural and non-structural elements such as plaster, bricks, beams, columns, parts of floors, but also fixed and / or movable furniture that may constitute an obstacle to opening the door. The artificial intelligence algorithms of the image processing software are trained on special databases to be able to distinguish said debris. The artificial intelligence algorithms are also trained to determine the level of debris in front of a door 1 (knowing in advance the opening side of one or more leaves) and thus being capable of determining whether the leaf can be opened, and if so, whether the size of the debris is large enough to allow the passage of people or to prevent it. This feature allows people, even in cases of poor visibility (such as in the case of smoke from a fire, or dust raised by partial collapses of the building) to identify, even from afar, the usability of a door 1 (FIG. 6). In fact, if the door could not be opened due to the presence of debris, the projectors 110, in some embodiments of the invention, would signal the fact that it is not possible to open it with a clear message, or even, to maximize visibility, by projecting a red screen or a red “X” (FIG. 6), having specifically informed users that, for example, a red screen corresponds to a non- usable door 1, while a green screen corresponds to a usable one. The ability to identify from afar whether the door is usable or not allows for faster and more effective evacuation in the event of an emergency. The apparatus 100 further comprises LED lights, buzzers and redundancy devices with autonomous batteries suitable for allowing the operation of the components of the apparatus 100 even in the absence of electrical energy from an electrical network.

[0076] Finally, it is clear that modifications, additions or variations that are obvious to a person skilled in the art can be made to the invention described so far, without thereby departing from the scope of protection provided by the attached claims.
