Description

[0001] The invention relates to an escape route safety device, in particular for escape doors in a building, according to the features of the preamble of claim 1.

[0002] In practice, escape route security devices are used to secure escape routes in buildings and to provide people in the building with a safe escape route in the event of danger.

[0003] DE 10 2010 019 103 A1 describes a door terminal control unit for escape and rescue routes. This door terminal control unit features a rectangular surface-mounted housing with an emergency switch, a key switch, and a keypad. To display complex information in plain text, this door terminal features a display.

[0004] In practice, it is advantageous if information on an escape door is clearly and unambiguously visible even from a considerable distance. Especially in the event of an emergency, for example, when escape routes are filled with smoke, good visibility of the escape route and, if applicable, the status of the escape door is of great importance.

[0005] The invention is based on the object of creating an escape route safety device which, with a structurally simple design, offers a visually easily comprehensible representation of information and wherein this information is particularly easy to perceive even from a certain distance or in unfavourable visibility conditions.

[0006] This object is achieved according to the invention by an escape route safety device having the features of claim 1.

[0007] According to the invention, an escape route securing device, in particular for escape doors in a building, is proposed, comprising a locking device cooperating with an escape door, and a door terminal connected to the locking device with an emergency switch for unlocking the locking device, wherein the door terminal has a display for displaying an escape route symbol, in particular a rectangular or square escape route symbol.

[0008] It is essential that the display has at least one light bar of a status indicator extending parallel to the edge of the display in an edge area.

[0009] One advantage is that the light bar, which extends parallel to the edge of the display, provides a relatively large and long area for the visual presentation of information, while also allowing for a relatively high luminosity. This increases the perceptibility and visibility of the information displayed by the status indicator.

[0010] In particular, the status indicator can display information using the light bars in different colors and / or, for example, in the event of an alarm, by blinking or flashing the light bar. In particular, the light bar can be designed as a multi-colored light bar.

[0011] Preferably, a light bar is understood to mean a linear light source. This linear light source can extend along an edge of the display, preferably in a straight horizontal and / or vertical line. The light bar can have a homogeneous luminous surface, such that the light bar illuminates with the same light color and / or the same luminous intensity across its entire surface.

[0012] Preferably, the light bar can also have a segmented luminous surface, so that different segments or areas of a light bar can be controlled with different colors or with different luminous intensities or with different luminous patterns or flashing patterns.

[0013] Preferably, an escape route safety device is understood to be one that is approved according to a standard for escape routes. For example, the escape route safety device meets the requirements of DIN EN 13637. Alternatively, the escape route safety device can also meet the national German standard EltVTR.

[0014] Preferably, the term locking device is understood to mean an escape route locking device, for example an escape door opener or a corresponding surface holding magnet.

[0015] In particular, an escape route symbol is understood to be an escape route symbol provided for in a standard which indicates an escape route.

[0016] Preferably, the term display is understood to mean a display which is designed as an active display and which, at least in one operating state,

[0017] Displays an escape route symbol, with the escape route symbol being illuminated or backlit. Alternatively, the display can also be designed as an actively controllable display for displaying various symbols and / or information.

[0018] In one embodiment, it can be provided that the light bar has several LEDs and / or is designed as an LED bar.

[0019] The LEDs ( L ight- E mitting- D LEDs (light-emitting diodes) can be designed as single-color and / or multi-color and / or controllable RGB LEDs. It can be provided that all LEDs of a light bar can be controlled jointly and / or that multiple LEDs of a light bar can be controlled in groups and / or that each individual LED of a light bar can be controlled individually. This allows one light bar to display either homogeneous lighting effects and / or multi-color lighting effects and / or different patterns.

[0020] Preferably, a countdown can also be displayed by means of the light bar, in which individual LEDs can be controlled individually and, for example, indicate the expiration of a predetermined period of time by one LED going out and / or another LED being additionally controlled as time progresses.

[0021] In order to increase visibility and / or perceptibility, it can be provided that the status display comprises at least two light bars which are arranged on opposite edge regions of the display, preferably arranged vertically in a right-hand region of the display and a left-hand region of the display.

[0022] Alternatively or additionally, it can be provided that the status display comprises a third light bar and / or a fourth light bar, which are arranged in an upper and / or a lower area of ​​the display, preferably arranged horizontally.

[0023] In order to display different information in an easily perceptible manner, it can be provided that the light bar or the light bars are each designed as a controllable multi-colored light bar for the targeted display of several colors, and / or that the light bars are designed to be controllable individually or in groups.

[0024] In one embodiment, the light strips can be arranged circumferentially around the escape route symbol, in particular, the light strips can frame the escape route symbol. The centrally located escape route symbol, which is illuminated and / or backlit, draws the eye to the display. By arranging the light strips around this escape route symbol, a person can see at a glance that this is an escape route and can also visually perceive specific information via the light strips.

[0025] In particular, the status indicator can indicate whether the door is locked or unlocked by changing the color of the light bars. For example, the color red can be selected for a locked door and green for an unlocked door. Furthermore, the status indicator can indicate an alarm, for example, by flashing or blinking one or more of the light bars. The alarm can also be displayed in an alarm color, for example, red and / or yellow.

[0026] Furthermore, the status display can, for example, indicate a pre-alarm by changing the color of the status display and / or indicate a time lapse by, for example, switching individual light bars on or off one after the other and / or by switching individual light elements of a light bar on or off one after the other according to the time lapse.

[0027] In particular, the escape route symbol can be designed as an illuminated escape route symbol or as an escape route symbol backlit by lamps.

[0028] In one embodiment, it can be provided that several buttons are arranged in the area of ​​the escape route symbol, in particular that a keyboard and / or a membrane keyboard is arranged in the area of ​​the escape route symbol. In particular, the several buttons or the keyboard or the membrane keyboard are arranged such that they partially cover the escape route symbol. This enables a particularly space-saving arrangement, since no additional space is required for the keyboard or the buttons.

[0029] To ensure the escape route symbol remains clearly visible, the multiple keys or the keypad or membrane keypad can be designed to be transparent or translucent, so that the escape route symbol is visible through the keys or the keypad or membrane keypad. In particular, the keypad or membrane keypad or keys are designed to be translucent or transparent in such a way that they do not obstruct the visibility of the escape route symbol.

[0030] In order to make an input, however, it is advantageous if the person can clearly see the keypad and / or the individual keys. For this purpose, the keys or the keypad or the membrane keypad can be provided with lighting which is switched on when activated and / or when the keys or the keypad or the membrane keypad are operated, so that the keys or the keypad or the membrane keypad become visible. This ensures that the escape route symbol is visible, and on the other hand, the keypad is visible when an input is made. One advantage is that the keypad or the keys share the same surface area with the escape route symbol, meaning the housing of the escape terminal can be more compact.

[0031] In particular, it can be provided that the display has a proximity sensor that switches on the lighting of the keyboard and / or the keys when the display is approached.

[0032] In one embodiment, the display can be provided with a touchscreen, and the escape route symbol can be displayed on the touchscreen. A touchscreen or a touch-sensitive display can combine both functions. The touchscreen can display both the escape route symbol and optionally other symbols or information. The touchscreen can also display buttons or a keyboard for operation or entering data or parameters.

[0033] Preferably, it can be provided that the door terminal or the escape route security device can be operated and / or parameterized via the plurality of buttons and / or the keypad and / or the membrane keypad. For example, parameters such as an alarm duration and / or a pre-alarm duration and / or an expiration time until the escape door is unlocked can be entered via the buttons and / or the keypad. It can also be provided that an alarm is reset via the keypad. Likewise, the keypad can be designed, for example, as an access control device, so that by entering a correct opening code or a PIN code when the door is locked, the escape door can be accessed without triggering an alarm.

[0034] To make the display more convenient to use when using a touchscreen, the display can be provided with a proximity sensor that, upon approach, activates several buttons and / or a keypad on the touchscreen for operating the door terminal and / or the locking device. This allows an escape route symbol to be displayed on the touchscreen, which can also be backlit. As soon as a person approaches the display, several buttons and / or a keypad for operating the door terminal and / or the locking device are displayed or activated on the touchscreen.

[0035] Preferably, the display can include a brightness sensor that controls the brightness of the escape route symbol and / or the brightness of the status indicator depending on the ambient brightness. For example, in bright environments, the brightness of the escape route symbol and / or the brightness of the status indicators can be increased, and in dark environments, the brightness can be reduced.

[0036] In one embodiment, the door terminal can be provided with an acoustic alarm device and / or a key switch. The acoustic alarm device can be used to indicate an alarm not only visually but also acoustically, for example by a signal tone. A triggered alarm can, for example, be reset using the key switch. Alternatively or additionally, the key switch can also be used to enter a secured, i.e. locked, door without triggering an alarm. Furthermore, the key switch can be used to verify the input of parameters or certain operating commands. In particularly compact embodiments of the door terminal, the function of the key switch can also be integrated into the keypad and / or the multiple buttons of the display in order to reduce the components of the door terminal and / or to make the door terminal particularly compact.

[0037] In particular, it can be provided that the locking device has a door opener, in particular an escape route door opener.

[0038] In order to enable simple installation, it can be provided that the display and the emergency switch are each designed as an independent unit that can be inserted separately into a housing of the door terminal or that can be inserted separately into a flush-mounted unit of the door terminal.

[0039] The escape route safety device according to the invention is intended for use on escape doors in buildings. The escape route safety device can be used for new installations in newly constructed buildings. However, it is also possible to retrofit existing systems with the escape route safety device according to the invention.

[0040] Further embodiments of the invention are shown in the figures and described below in the description of the figures. Herein: Fig. 1: a schematic representation of an escape route security device according to the invention; Fig. 2: an exemplary design of the upper area of ​​the door terminal with a display and membrane keypad; Fig. 3: an exemplary design of the upper area of ​​the door terminal with a touchscreen.

[0041] The Figures 1 to 3show exemplary embodiments of the invention. In particular, the figures are not intended to be limiting. In the figures, functionally identical devices and / or functions are provided with the same reference symbols. It is clear to the person skilled in the art that, within the scope of protection defined by the claims, they can combine the features illustrated in the figures with one another in order to adapt the escape route safety device to local requirements based on their specialist knowledge, without thereby departing from the scope of protection.

[0042] The Fig. 1shows an escape route securing device 1 on an escape door 9. The escape door 9 has a rotatable door leaf 91. The door leaf 91 is rotatably mounted on a door frame 92 via door hinges 93a, 93b. Furthermore, the door leaf 91 has a door lock 94, which is designed as a mortise lock and cooperates with a lock countercase 95 arranged in the door frame 92 to lock the door in the closed position. Furthermore, the escape route securing device comprises a locking device 2. In the Fig. 1 In the example shown, the locking device 2 is shown as an escape route door opener 2, which is arranged in the door frame 92 and interacts with a bolt arranged in the door leaf 91 to lock or release the door 9.

[0043] A door terminal 3 is mounted on the wall in the area of ​​the escape door 9. The door terminal 3 has a housing 31 in which an emergency switch 32 or emergency button 32, a key switch 33, and a display 4 are arranged.

[0044] In an emergency, the emergency switch 32 can be used to open the escape door 9, generating an alarm when the emergency switch is triggered. For example, the key switch 33 can be used to reset the alarm, or an authorized person can access the secured escape door 9 without triggering an alarm. The display 4 is designed as an active, i.e., illuminated display and shows an escape route symbol 6, so that it is clearly visible to a person that this door 9 is an escape door.

[0045] The door terminal 3 is connected to the locking device 2 via a cable connection 34 and / or a bus connection 34 in order to control the locking device 2 for unlocking and / or locking. Alternatively and / or additionally, the door terminal 3 can also be connected to other components, such as a central escape route control device and / or the door lock 94, via the cable connection 34 and / or bus connection 34.

[0046] In the Fig. 2The door terminal 3 is shown with its housing 31 in the upper area of ​​the display 4. In this exemplary embodiment, the display 4 includes a backlit escape route symbol 6. The escape route symbol 6 can be displayed, for example, using a glass plate and / or Plexiglas plate containing the escape route symbol and illuminated from the back by a light source. Light strips 41, 42, 43 are arranged around the escape route symbol 6 on three sides. The light strips each have an LED strip 411, 421, 431.

[0047] Together, the light strips 41, 42, and 43 form a status indicator 44. This status indicator 44 can be used, for example, to indicate the status of the escape door 9, in particular whether it is locked or unlocked. For example, when the escape door is locked, the status indicator can light up red and when it is unlocked, green. In the event of an alarm, the status indicator can flash to provide visual attention to the alarm. The status indicator can also include one or more briefly flashing LEDs (flash), or moving light points, each represented by a lit LED, or a progress bar.

[0048] It can be provided that the two opposing, vertically extending light bars 41 and 42 are connected together as a group, each visually displaying the same status and / or information. The upper light bar 43, which is arranged horizontally, can be used to display special information. Such special information can, for example, be the display of information regarding the operating status and / or a specific operating menu and / or error information.

[0049] A sensor 45 is arranged in the housing 31 of the door terminal 3. This sensor can be designed as a combined proximity sensor and brightness sensor. This makes it possible to use the sensor 45 to control the brightness of the escape route symbol 6 and / or the status indicator 44.

[0050] The proximity sensor 45 can be used to activate the keypad 5, which is arranged on the display 4 in the area of ​​the escape route symbol 6.

[0051] The keyboard 5 has several individual keys 511, 512, 513. In the figure of the Figure 2 Only these three keys have been marked with reference symbols to maintain clarity. Keypad 5 is designed as a transparent keypad, specifically a transparent membrane keypad, and is invisible or only slightly visible during standard operation. As a result, keypad 5 does not impede the visibility of the escape route symbol 6, or only very slightly.

[0052] When proximity sensor 45 is triggered, it activates the illumination 52 of keypad 5 or the escape route symbol 6. The illumination 52 illuminates the dividing lines between the individual keys. At the same time, the individual keys 511, 512, and 513 of keypad 5 are clearly visible. This makes it possible to accommodate both the escape route symbol 6 and an input device using keypad 5 or membrane keypad 5 on the same surface.

[0053] In the Fig. 3 An embodiment of the door terminal 3 is shown with its door housing 31 and a display 4, which has a touchscreen 7. The escape route symbol 6 is also displayed on the touchscreen 7. The status display 44 is arranged around the touchscreen 7, as in the previous example. The status display 44 has light bars 41, 42, and 43, each of which includes an LED light bar 411, 421, 431.

[0054] In this example, a sensor 45 is also present, which is designed as a combined proximity and brightness sensor 45. The brightness sensor 45 can be used to adjust the brightness of the touchscreen 7 to the ambient brightness in order to improve visibility and / or readability.

[0055] Via the proximity sensor 45, a keypad 5 can be displayed or activated on the touchscreen 7 in addition to the escape route symbol 6 to operate the door terminal 3. Operation can include, on the one hand, parameterization or setting of the door terminal 3. On the other hand, operation can also include resetting an alarm and / or access control, so that the secured escape door 9 can also be accessed without triggering an alarm. For this purpose, a code, for example a PIN number, can be entered via the keypad 5 and / or the touchscreen 7 to release the door 9 for access.

[0056] To achieve a visually appealing design, the display 4 can be provided with a cover frame, for example, a cover glass, which is green in the edge area. The green color of the edge area can correspond to the green color of the escape route symbol and / or the color of the door terminal 3.

[0057] In particular, it can be provided that the display 4 is designed as a rectangular and / or square display 4.

[0058] The side lengths of the display 4 can, for example, range from 35 mm to 145 mm, preferably between 45 mm and 90 mm. This ensures good visibility of the display even at greater distances.

[0059] In an alternative embodiment, the touchscreen 7 can also be designed as a capacitive touchscreen, wherein the proximity sensor can be formed by the touchscreen 7 itself. By changing the capacitance of the touchscreen 7 when a hand approaches, the approach of an operator can be detected and a keyboard 5 can be displayed. List of reference symbols
