Building sliding door system with edge-spanning electronic display device

Description

[0001] The invention described here generally relates to the technical equipment of a building. Embodiments of the invention relate in particular to the technical building equipment for separating access to the building or to an interior space of the building, and to a method for operating the technical building equipment. Buildings can be equipped in a variety of ways to separate access to the building or, within the building, access to an interior space. In a building, the separation is often achieved by doors. A door can be designed as a hinged door with a movable door leaf that is rotatably attached to the door frame (jamb, door casing) with two or more hinges (door hinges), or as a folding door in which one or more door leaves are divided into several parts by hinge bands or flexible strips that fold out from the closing plane when opened.Sliding doors are also known that are attached to the frame by means of guide rails in which the door leaf is suspended or inserted and can be moved laterally. EP 2 8166 241 B1, for example, describes a sliding door that can be moved in a frame structure between a closed position and an open position. In the closed position, the sliding door is flush with the surrounding wall, and in the open position, a recess in the wall at least partially accommodates the sliding door. WO 2020 / 182511 A1 and WO 2006 / 074785 A1 describe sliding doors with a display device.

[0002] The systems mentioned relate to different requirements for building doors and their respective designs within a building. In addition to these known requirements, further demands arise, for example, due to changing lifestyles and living conditions (e.g., densely populated apartment buildings in a city), a need for increased security, and increasing automation of and within buildings. Therefore, there is a need for a technology that enables further automation of the operation of a building door.

[0003] One aspect of the invention relates to a building sliding door system that separates a first building area from a second building area. The building sliding door system comprises a frame structure that has a door frame area, a passage area, and a wall shell area. A sliding door is displaceable in the frame structure between a closed position and an open position along a sliding axis. The sliding door has a front side and a door leaf, wherein the wall shell area at least partially accommodates the sliding door in the open position. The front side points towards the passage area and extends transversely to the sliding axis. The door leaf extends from the front side essentially parallel to the sliding axis. An electromechanical drive unit and a control device are designed to displace the sliding door.In addition, an electronic display device is provided, which is arranged at a defined height on the sliding door and connected to the control device. The display device has a user interface that extends across the edges between a defined area of ​​the front side and a defined area of ​​the door leaf. The control device is designed to control the display device for information display, with the information being displayed on the door leaf side and / or the front side.

[0004] Another aspect relates to a method for operating the building sliding door system. According to the method, the electronic display device for an information display is controlled by the control device such that the information display occurs on the door leaf side and / or the front side.

[0005] The invention described here creates a building sliding door system in which the electronic display device, or the information displayed by it, can be perceived by a user in both the closed and open positions of the sliding door. In the (fully) open position, the door-side portion of the display device can protrude fully or partially into the wall shell area and be concealed by it, while the front portion of the display device remains visible and can display information there.

[0006] In one embodiment, the control device controls the display device as a function of a determined position of the sliding door, in particular as a function of a distance D between the front side and the door frame area, wherein the information is displayed on the door leaf side in the closed position of the sliding door, on the front side in the open position, and on the door leaf side and / or front side in an intermediate position. For example, the information can be displayed during opening in such a way that the information to be displayed (from the perspective and perception of a user standing in front of the sliding door) is shifted virtually seamlessly from a display on the door leaf side to the display on the front side, so that it can be perceived as best as possible by the user during opening.

[0007] In one embodiment, the display is shifted to the front-side display when the distance D reaches or exceeds a specified threshold. The threshold can be selected for the specific building and / or application. In one embodiment, the threshold is approximately 80%, i.e. the sliding door is 80% open. In one embodiment, a flow mode begins when the threshold is reached; with a threshold of approximately 80%, the information display is therefore only shifted from the door-side display towards the front side when the sliding door is already relatively wide open. The information can therefore be perceived by the user even when the sliding door is essentially fully open.

[0008] Various technologies can be used to determine the position of the sliding door. In one embodiment, a rotary encoder present in the electromechanical drive unit can be used, which detects a change in angle when the sliding door is moved by the drive unit. The control device is designed to determine the position of the sliding door, in particular the distance D between the front side and the door frame area, from the change in angle. In another embodiment, a sensor unit arranged on the sliding door (e.g., a 3D camera) can be used, which is connected to the control device and determines the distance D in order to determine a position of the sliding door from the distance D.

[0009] Depending on the type or use of the building or the sliding door system, the display device can comprise at least one further device for an additional functionality. In one embodiment, a visible (multifunctional) unit can be arranged on the sliding door in a single location, thereby facilitating installation, maintenance, and cleaning. The further devices can, in particular, comprise a video camera for a peephole function and / or for capturing an optical code, a radio unit for capturing authorization and / or for communicating with a user's mobile phone, a loudspeaker, a proximity sensor for detecting an approaching user, and / or an LED lighting device for illuminating the display device and / or an area surrounding the sliding door.Those skilled in the art will recognize that one or more of these devices may be located external to the display device; for example, a video camera may be located at a typical head / face height of a standing adult.

[0010] The invention is explained in more detail below using exemplary embodiments in conjunction with the figures. In the figures, like elements have like reference numerals. They show: Fig. 1 shows a schematic perspective view of an embodiment of a building sliding door system with a partially opened sliding door and a display device arranged thereon; Fig. 2A-2D show schematic representations of the display device according to Fig. 1 with an exemplary information display; Fig. 3 a flowchart of an embodiment of a method for operating the building sliding door system; and Fig. 4A-4C schematic representations of the sliding door according to Fig. 1 in different positions (closed position, partially open position, fully open position).

[0011] Fig. 1 is a schematic perspective representation of an embodiment of a building sliding door system 1 for separating a first building zone 21 from a second building zone 22. The building sliding door system 1 can, in one embodiment, be part of an interior building wall. For example, in an apartment building, it can separate the private interior area of ​​an apartment (e.g., the first zone 21) from a (non-private) exterior area (e.g., hallway or stairwell) (e.g., the second zone 22). Analogously, the building sliding door system 1 can, for example, be used in an interior building wall in an office building, hotel, or the like; in a hotel, the building sliding door system 1 can, for example, separate two adjacent rooms. In another embodiment, the building sliding door system 1 can be part of an exterior building wall. For example, it can separate the interior area (e.g., the first zone 21) of a non-public building (e.g.,A residential building, hotel, commercial building, etc.) is separated from the public outdoor area (e.g., a street or public square) (e.g., the second zone 22). In the following, the first zone 21 is referred to as the interior zone 21, and the second zone 22 is referred to as the exterior zone 22.

[0012] The building sliding door system 1 comprises, in the illustrated embodiment, a frame structure 2 in which different areas can be defined. For illustration and differentiation, these areas are referred to below as door frame area 2a, passage area 2b and wall shell area 2c. The building sliding door system 1 further comprises a sliding door 4, which is displaceable in the frame structure 2 between a closed position and an open position along a sliding axis x. In the closed position, the sliding door 4 closes the passage area 2b, and in the open position, the sliding door 4 completely or partially releases the passage area 2b, so that, for example, a person, a pet or a robot can pass from one of the zones 21, 22 into the other zone. In the Fig. 1 In the partially open position shown, an end face 30 of the sliding door 4 has a distance D from the door frame area 2a. Further details on the mechanical construction of the frame structure 2 and the sliding door 4 are given elsewhere in this description.

[0013] In Fig. 1 It is indicated that the building sliding door system 1 comprises electronic and electromechanical system components and is connected to a building control system 20 (BM). In one exemplary embodiment, the building sliding door system 1 is communicatively connected to the building control system 20 (BM). An electrical interface device 16, a control device 12 (DC), a drive unit 14 (M), a sensor unit 18 and an electronic display device 10 are shown as exemplary system components of the building sliding door system 1. The control device 12 controls the opening and closing of the sliding door 4 and stores a current operating state of the sliding door 4 in a memory device 12a (D%) for at least a specified period of time. This includes, among other things, information about the distance D of the front side 30 to the door frame area 2a, wherein the distance D can vary between zero and a maximum distance Dmax (0 ≤ D ≤ Dmax).The control device 12 thus contains information indicating whether the sliding door 4 is closed (D = 0), fully open (D = Dmax), or partially open (0 < D < Dmax). The distance D can be specified as an absolute value (length, e.g., in centimeters) or as a percentage. Exemplary embodiments of how this distance D can be determined are given elsewhere in this description.

[0014] In the Fig. 1 In the situation shown, a building sliding door system according to the invention can be advantageously used. Briefly and by way of example, the invention described here enables the electronic display device 10, or the information displayed by it, to be perceived by a user in the closed position and in the open position. For this purpose, the display device 10 is arranged at a defined height (e.g., between approximately 1 m and 1.5 m) on the sliding door 4. A user interface 10a of the display device 10 extends across edges between a defined area of ​​the front side 30 and a defined area of ​​a door leaf 26 of the sliding door 4.Since a cavity in the wall shell area 2c accommodates the sliding door 4 in the (fully) open position, the door leaf-side part of the display device 10 can protrude completely or partially into the wall shell area 2 and be concealed by it, while the front part of the display device 10 is visible and information can be displayed there. The control device 12 accordingly controls the display device 10 for information display via an electrical connection 33. In one exemplary embodiment, the control device 12 controls the display device 10 as a function of a determined position of the sliding door 4, in particular as a function of the distance D, wherein the information is displayed on the door leaf side in the closed position of the sliding door 4, on the front side in the open position, and on the door leaf side and / or front side in an intermediate position.For example, when opening a door, the information can be displayed in such a way that it moves seamlessly from a door leaf-side display to the front-side display, allowing the user to perceive it as best as possible. In one embodiment, the display moves to the front-side display when the distance D reaches or exceeds a specified threshold. Example display options are shown in . Fig. 2A - Fig. 2C shown. In this description, the terms "flow," "move," "press," "flow process," and "flow mode" are used to describe and characterize a process, particularly from the perspective and perception of a user.

[0015] Schematic representations of an embodiment of the display device 10 are shown in Fig. 2A - Fig. 2D shown. Electrical connections or lines for connection to the control device 12 are not shown; however, the person skilled in the art will recognize that these are present. The person skilled in the art will also recognize that the display device 10 can comprise control electronics (not shown). The display device 10 is designed such that its user interface 10a extends across edges between a defined area of ​​the front side 30 and a defined area of ​​the door leaf 26. In one embodiment, the display device 10 has a front-side segment 6 and a door leaf-side segment 8, which in the embodiments shown are arranged at an angle to one another, essentially at right angles; this is particularly evident in the Fig. 2D This can be seen in the top view shown. These can be two separate segments 6, 8 (individual display devices) that are connected to one another at or in the region of the edge and controlled by the control device 12 or the control electronics of the display device 10 such that the information display is shown across the edges. In another embodiment, a (single or one-piece) curved display device can comprise the segments 6, 8, as explained elsewhere in this description.

[0016] From the Fig. 2D The plan view shown also shows that the segments 6, 8 in the exemplary embodiments shown are of different lengths (in the x-direction and y-direction) (L-shaped arrangement), with the shorter segment 6 extending in the y-direction on the front side and the longer segment 8 on the door leaf side in the x-direction. In the z-direction, the segments 6, 8 have the same length. In another exemplary embodiment, the segments 6, 8 can be of equal length in the x-direction and y-direction, or the front-side segment 6 can be longer than the door leaf-side segment 8. In one embodiment, the segments 6, 8 can be longer in the z-direction than in the x-direction and y-direction, resulting in an upright display device 10. The dimensions of the display device 10, in particular the size of the segments 6, 8, can be determined depending on the type of building and / or the scope of the information to be displayed.

[0017] From the representations of the Fig. 2A - Fig. 2D It is also evident that the display device 10 or its user interface 10a extends across the edges. In other words, the user interface 10a does not end on the front or door leaf side at or in front of the edge between the door leaf 26 and the front side 30 and then begin again on the other side at this edge as a new, second user interface 10a, but rather it is a user interface 10a that covers the edge, encompasses it, begins on one side and continues on the other side. The display device 10, which is in particular bent in one piece, comprises in one embodiment a light-emitting diode network (also known as LED network or LED fabric) or a flexible light-emitting diode screen (LED (display) unit), in particular consisting of LEDs that are attached to a flexible carrier material (flexible circuit board), which in turn is embedded in a fabric.Flexible display devices can also include organic LEDs (OLEDs), each resulting in an OLED unit. These can also be configured as touch-sensitive display devices, whose structures and functionalities, including information on electronic control, are known, for example, from US 2017 / 0336831 A1 and WO 2013 / 048881 A1. In another embodiment, the display device 10 comprises an LCD unit, which can also be configured to encompass edges.

[0018] In one embodiment, the display device 10 has a glass or plastic surface that extends over the user interface 10a. The glass or plastic surface can be shaped to extend seamlessly over the segments 6, 8 and a curve therebetween, as shown in the illustrations of the Fig. 2A - Fig. 2D is visible. So that the information display can be perceived by a user, the glass or plastic surface is transparent to visible light. In addition, the glass or plastic surface can be designed such that the display device 10 can be configured as a touch-sensitive display device. In addition to these properties, the glass or plastic surface protects the display device 10 from damage and enables easy cleaning. Methods for producing glass or plastic surfaces with the aforementioned properties are known to those skilled in the art.

[0019] According to the invention, the display device 10 is used to display information, which can inform a user, for example, about the status of the sliding door 4, its use, and / or about the condition of the building or the zone 21, 22 separated by the sliding door 4. The information can be displayed using pictograms, symbols, and / or text; pictograms or symbols can, for example, inform that the sliding door 4 is locked, that the sliding door 4 is unlocked, that certain actions are undesirable or prohibited (e.g., smoking or making phone calls), and that access is not permitted. Text, alone or in combination with a pictogram or symbol, can, for example, be an instruction or notification (e.g., "Please touch," "Please wait," "No access," "Do not disturb," "Emergency exit," "Escape route," "Fire alarm," or similar) or display the user's name.In addition, in one embodiment, an audible signal and / or a voice message corresponding to the pictogram or symbol can be initiated.

[0020] If the sliding door 4 is in the closed position, the display device 10 is controlled so that information is displayed on the door leaf side segment 8, as shown in Fig. 2A The front segment 6, which is essentially covered by the door frame area 2a in the closed position, is not activated. Fig. 2C the sliding door 4 is in the open position and the display device 10 is controlled in this embodiment such that information is displayed on the front segment 6. Between these two positions of the sliding door 4, the display device 10 is controlled such that information is displayed on the front segment 6 and / or the door leaf segment 8, as shown in Fig. 2B is shown as an example. In one embodiment, the control is carried out in such a way that the information display when the sliding door 4 moves into the wall shell area 2c is perceived by the user as if the information display were being "pushed" forward by the wall shell area 2c, as if the display content were stationary while the sliding door 4 continues to move; in conjunction with the Fig. 4 In the flow diagram shown, this is illustratively referred to as flow mode. In one embodiment, this flow mode begins when the distance D reaches or exceeds the specified threshold value; in one embodiment, this threshold value is 80%, i.e. the sliding door 4 is 80% open. Until the door is 80% open (e.g., until the display device 10 begins to disappear into the wall shell area 2c), in this embodiment, the door leaf-side segment 8 remains active and displays the information. The flow process only begins shortly before the sliding door 4 is fully opened. A person skilled in the art will recognize that the flow process with regard to the information display can take place during the entire opening process or only towards the end of the opening process. A person skilled in the art will also recognize that a different threshold value can be selected depending on the type and use of the building or of the sliding door 4.The person skilled in the art will recognize that, analogous to the opening process, during the closing process the information display can be shifted from the front-side segment 6 to the door leaf-side segment 8; for example, the shifting can begin when the threshold value (80%) is reached during the closing process.

[0021] As mentioned above, the control of the display device 10 or its user interface 10a for displaying information takes place as a function of a determined position of the sliding door 4, in particular as a function of the distance D. In one embodiment, a rotary encoder integrated in the drive unit 14 (motor) can be used to determine the position of the sliding door 4 or the distance D. Rotary encoders (also called incremental encoders or encoders) are known to those skilled in the art; they can be designed to detect angular changes and a direction of rotation. If the motor rotates to move the sliding door 4, each angular change by a specified angle to the left or right leads to a specified change in a manipulated variable (e.g.The distance traveled by the sliding door is increased or decreased by one (increment (+1) or decrement (-1)); if the values ​​for the closed position and the open position of the sliding door 4 are known, the distance (D) can be determined from the angle change or the distance traveled. The values ​​for the closed position and the open position of the sliding door 4 can be determined, for example, during commissioning of the sliding door 4 by an initialization run.

[0022] In one embodiment, the sensor unit 18 can be used to determine the position of the sliding door 4 or the distance D. The sensor unit 18 is connected to the control device 12 by an electrical connection 32 and arranged in an area of ​​the front side 30 of the sliding door 4. The arrangement of the sensor unit 18 can be selected such that the passage area 2b can be monitored and the distance D can be determined. The monitoring can be used to detect whether the passage area 2b is clear, i.e. there is neither a user nor an obstacle there, and the sliding door 4 can be closed. The arrangement can be selected such that electromagnetic radiation (light or radio waves) emitted by the sensor unit 18, for example, can propagate unhindered in the direction of the passage area 2b during operation.If the sensor unit 18 comprises a camera that detects in the infrared or visible electromagnetic spectrum, the arrangement can be selected so that the passage area 2b is in the camera's "field of view." The sensor unit 18 can, for example, be inserted into a recess on the front side 30 and protected from damage and dirt by a radiation-permeable cover. To determine the distance D, the sensor unit 18 can also be arranged at a height such that, under normal circumstances, there is no obstacle or user between the sensor unit 18 and the door frame area 2a.

[0023] For these functions, the sensor unit 18 can comprise one or more sensors, for example, one or more sensors or 3D cameras based on the principle of time-of-flight (TOF) measurement. Such a 3D camera comprises a light-emitting diode or laser diode unit that emits light, for example, in the infrared range, with the light being emitted in short pulses (e.g., several tens of nanoseconds long). The 3D camera also comprises a sensor group consisting of a number of light-sensitive elements. The sensor group is connected to a processing chip (e.g., a CMOS sensor chip) that determines the time of flight of the emitted light. The processing chip simultaneously measures the distance to a number of target points in space in a few milliseconds. The 3D camera can also be based on a measurement principle in which the time of flight of emitted light is recorded via the phase of the light.The phase position during transmission and reception of the light is compared, and the elapsed time or distance to the reflecting object is determined from this. For this purpose, a modulated light signal is preferably emitted instead of short light pulses. Further details on these measurement principles can be found in the following publications, for example: "Fast Range Imaging by CMOS Sensor Array Through Multiple Double Short Time Integration (MDSI)", P. Mengel et al., Siemens AG, Corporate Technology Department, Munich, Germany, and "A CMOS Photosensor Array for 3D Imaging Using Pulsed Laser", R. Jeremias et al., 2001 IEEE International Solid-State Circuits Conference, page 252.

[0024] In another embodiment, the functionality of the sensor device 18 and the functionality of the display device 10 can be combined in one device; for example, the functionality of the sensor device 18 can be implemented in the display device 10, as shown in Fig. 2D shown. For the functionality of the sensor device 18, the 3D camera can be arranged, for example, on the front side under the glass or plastic surface of the display device 10. In one embodiment, at least one further device for a further functionality can be implemented in the display device 10. Fig. 2D shows an embodiment with several such devices, shown as examples are a video camera 10d for a door spy function and / or for capturing an optical code (e.g. a barcode, a matrix code (QR code)), a radio unit 10b, 10c (e.g. according to a standard for RFID or Bluetooth technologies) for capturing an authorization credential and / or for communicating with a user's mobile phone, a loudspeaker 10e, a proximity sensor 10f for detecting an approaching user, and / or an LED lighting device 10g for illuminating the display device 10 and / or an area surrounding the sliding door 4. These devices can be connected to the control device 12 via an interface device 10. Alternatively, the devices can be connected exclusively or additionally to the control electronics of the display device 10 in order to be controlled by it and / or to communicate with it.The devices mentioned and their modes of operation are known to the person skilled in the art, so that further explanations on this point do not appear necessary.

[0025] With the understanding of the principal system components and their functionalities described above, the following in connection with Fig. 3 a description of an exemplary method for operating the building sliding door system 1 starting from the Fig. 1 shown situation. The Fig. 3 The process shown begins in one step S1 and ends in one step S8. The person skilled in the art will recognize that the division into these steps is exemplary and that one or more of these steps can be divided into one or more sub-steps or that several of the steps can be combined into one step.

[0026] In one step S2The status of sliding door 4 is determined. As explained above, the distance D between the front end 30 and the door frame area 2a can be determined using the rotary encoder, for example. This determines the status of sliding door 4: sliding door 4 closed (D = 0), fully open (D = Dmax), or partially open (0 < D < Dmax).

[0027] In one step S3 it is checked whether the sliding door 4 is closed, ie D = 0. If this is the case, the process proceeds along the yes branch to a step S5. When the sliding door 4 is closed, the step S5 the information display on the door leaf side. The control device 12 controls the display device 10 accordingly.

[0028] If the test in step S3, that the sliding door 4 is not closed, the process proceeds along the No branch to a step S4. In step S4it is checked whether the sliding door 4 is fully open, ie D = Dmax. If this is the case, the process proceeds along the yes branch to a step S6. When the sliding door 4 is fully opened, the step S6 the information display on the front. The control device 12 controls the display device 10 accordingly.

[0029] If the test in step S4 against the fact that the sliding door 4 is not fully opened, the process proceeds along the No branch to a step S7. The sliding door 4 is therefore neither closed nor fully open. In this status of the sliding door 4, the information display takes place in step S7 in the flow mode (here referred to as an example), in which the information display is moved from one segment 6, 8 to the other segment 6, 8. In Fig. 3 the procedure ends in step S8.

[0030] A person skilled in the art will recognize that the status of the sliding door 4 changes, for example, when it is operated by a user, e.g., to open it. If the sliding door 4 is subsequently fully opened, it can remain in the fully open position for a specified period of time and then close automatically.

[0031] Referring again to Fig. 1 The following describes further details of the mechanical structure of the frame structure 2 and the sliding door 4. The door frame area 2a is located to the left of the passage area 2b, although it can also extend beyond the passage area 2b, and the wall shell area 2c is located to the right of the passage area 2b, although it can also extend beyond the passage area 2b. The passage area 2b is thus surrounded by the door frame area 2a, the wall shell area 2a, and a building floor or a threshold or guide rail arranged there.

[0032] On the frame structure 2, a wall panel 25 facing the inner zone 21 (hereinafter also referred to as inner wall panel 25), a wall panel 23 facing the outer zone 22 (hereinafter also referred to as outer wall panel 23), and lateral fastening devices 17 are arranged. The inner wall panel 25 is arranged essentially parallel to the outer wall panel 23, wherein the wall panels 23, 25 cover (clad) in particular the door frame area 2a and the wall shell area 2c and can be adapted to the surrounding wall in terms of design. The lateral fastening devices 17 are provided for connecting the building sliding door system 1 to the building. With reference to the Fig. 1 In the xyz coordinate system shown, the building sliding door system 1 has a length in the x-direction, a depth in the y-direction, and a height in the z-direction; the building sliding door system 1 extends in a plane spanned by the x- and z-axes. The sliding door 4 is movable in the x-direction along a sliding axis. In the Fig. 1 In the illustration shown, the sliding axis corresponds to the x-axis; in this illustration, the sliding axis therefore has the reference symbol x (sliding axis x).

[0033] The wall shell area 2c comprises a cavity between the wall panels 23, 25, which is dimensioned to at least partially accommodate the sliding door 4 in the open position. The sliding door 4 has two substantially parallel door leaves 26 (each on an inner side and an outer side of the sliding door 4) and the end face 30, which faces the passage area 2b and extends transversely to the sliding axis x. Starting from the end face 30, the door leaves extend substantially parallel to the sliding axis x and are spaced apart from one another (in the y-direction), such that an interior space exists between the door leaves 26 in which system components and insulating material, e.g., for sound and fire protection, can be arranged. Each of the door leaves 26 extends substantially parallel to the xz plane.

[0034] In Fig. 1 In the embodiment shown, the building sliding door system 1 is connected to the building control system 20 (BM) by means of an electrical connection 28. The building sliding door system 1 can be supplied with electrical energy, for example, via this connection 28. In one embodiment, the supplied energy can ensure operation of the building sliding door system 1 without the need for external control signals or control commands. System components that, for example, check a key, an access code, or another type of access authorization are (locally) integrated into the building sliding door system 1 in this embodiment, so that it can be operated autonomously—except for the electrical energy.

[0035] The control device 12 is also connected to the drive unit 14 and the interface device 16 by means of an electrical connection 34. The electrical connection 32 between the sensor unit 18 and the control device 12 and the electrical connection 34, as well as the electrical connection 33 between the control device 12 and the display device 10, run within the sliding door 4, for example, between the door leaves 26. The electrical connections 32, 33, 34 are designed for signal and / or energy transmission; for this purpose, they can each comprise individual electrical lines or an electrical bus system.

[0036] In one embodiment, external control signals or control commands can be supplied to the building sliding door system 1, for example, in connection with verifying access authorization. In this embodiment, the electrical interface device 16 is also provided for communication between the building control system 20 and the building sliding door system 1. For this purpose, the electrical connection 28 comprises a communications network to which the building control system 20 and the interface device 16 are coupled. The building control system 20 can comprise a computer-based building management system in which data on authorized users and objects are stored.

[0037] Those skilled in the art will recognize that the building control system 20 can be located in building 2, wherein the building control system 20 is configured as a local unit independent of an external system for operating the building sliding door system 1 (or even several such systems). In one embodiment, functions of the building control system 20 can be distributed among subsystems or components located locally in and remotely from building 2. For this purpose, the subsystem located in building 2 can be coupled to an IT infrastructure for so-called cloud computing (colloquially also referred to as "cloud"). This includes, for example, storing data in a remote data center, but also executing programs that are not installed locally but remotely. Depending on the configuration, a specific functionality can be provided, for example, in the control device 12 or via the "cloud."For example, a software application or parts of it can be executed in the cloud. The control device 12 then accesses this infrastructure via the interface device 16 as needed to execute the software application.

[0038] The electrical connection 28 can comprise an electrical bus system in one embodiment. In one embodiment, the electrical connection of the building sliding door system 1, including its supply with electrical power, is established via the interface device 16. Those skilled in the art will recognize that multiple building sliding door systems 1 can be present in the building 2, and that each of these building sliding door systems 1 can be coupled to the electrical connection 28 to communicate with the building control system 20, for example, in connection with determining and verifying access authorizations, if this is done centrally by the building control system 20.

[0039] The following describes the operation of the building sliding door system 1 with reference to Fig. 4A - Fig. 4C described. Fig. 4A - Fig. 4C each show a schematic representation of a horizontal cross-section of an embodiment of the building sliding door system 1 with the sliding door 4. In each of these representations, the components comprised by the sliding door 4, namely the sensor unit 18 (S), the control device 12 (DC), the display device 10, and the drive unit 14 (M), are shown; for illustrative reasons, the interface device 16 and its connection to the building control system 20 are not shown. The drive unit 14 and the control device 12 are arranged within the sliding door 4, in particular between the door leaves 26.

[0040] The illustrated embodiment of the building sliding door system 1 is based on a principle similar to that known from EP 28166241 A1. This describes a sliding door system in which two opposing door surfaces are coupled to an actuator that moves the door surfaces toward or away from each other. With respect to the building sliding door system 1 according to the invention described here, this means that the two door leaves 26 have a leaf spacing d1 in the closed position of the sliding door 4. During the opening of the sliding door 4, the two door leaves 26 are moved by an actuator 9 ( Fig. 4A - Fig. 4C ) are moved towards each other to such an extent that they have a leaf distance d2 which is dimensioned such that the sliding door 4 in its fully or partially open position ( Fig. 4B und Fig. 4C ) has such a small thickness that it fits into the receiving structure of the wall shell area 2c. The leaf distance d1 is greater than the leaf distance d2. When the sliding door 4 is pushed out of the wall shell area 2c, the two door leaves 26 are moved away from each other (spread apart), so that the sliding door 4 in the closed state ( Fig. 4A ) has a specified thickness. The thickness is determined such that the outer sides of the two door leaves 26, in the closed position, are essentially flush with the outer sides of the wall shell area 2c, or its cladding (wall panels 23, 25). This achieves a substantially smooth finish on both sides of the wall in the door area.

[0041] In one embodiment, the building sliding door system 1 has a guide device on a door cross member, which supports the sliding door 4 and guides it on its path between the closed position and the open position. For this purpose, the sliding door 4 has a complementary device on its upper edge. The guide device and the complementary device interact when the drive unit 14 causes the sliding door 4 to move and, for example, acts on the complementary device. The guide device and the complementary device form, for example, a roller mechanism (e.g., a roller-bearing carriage system (roller carriage)). The drive unit 14 can, for example, comprise a motorized or pneumatic sliding drive, which, for example, acts on the sliding door 4.The person skilled in the art will recognize that the design is not limited to a roller mechanism and that the guide device and the complementary device can be designed in a different way, for example as a telescopic extension.

[0042] In one embodiment, the two door leaves 26 are moved toward or away from each other by the actuator 9. The actuator 9 can comprise a spreading device that is activated mechanically, electrically, or electromechanically. The spreading device is designed to move the door leaves 26 toward each other when the sliding door 4 is to be opened and to move them away from each other when the sliding door 4 is to be closed. Those skilled in the art will recognize that other spreading devices, for example, pressure-operated cylinders, can also be provided instead.
