Description

Technical Field

[0001] The technologies described herein generally relate to the technical equipment used in buildings. In particular, embodiments of this technology relate to technical building equipment for separating entrances to a building or its interior, and to a method for operating such technical building equipment. Background Technology

[0002] Buildings can be equipped in various ways to separate entrances to the building or entrances to interior spaces within the building. In buildings, separation is typically achieved through doors. Doors can be designed as stop doors with movable door panels rotatably fixed to a door frame (frame, door casing) by two or more hinges (door hinges), or as folding doors, in which one or more door panels are divided into several sections that fold when opened from the closing plane by hinge bands or flexible strip structures. Sliding doors are also known, which are attached to a frame via a running track, with the door panels suspended or inserted into the frame and capable of lateral movement. For example, EP2876241B1 describes a sliding door that can move between a closed position and an open position within a frame structure. 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.

[0003] The systems mentioned pertain to various requirements of building doors and their related designs. Beyond these known requirements, other demands exist, such as the need for increased building security and greater automation due to changing lifestyles or living conditions (e.g., dense housing in urban apartments). Therefore, technologies capable of further automating the operation of building doors are needed. Summary of the Invention

[0004] One aspect of this technology relates to a building sliding door system that separates a first building area from a second building area. The building sliding door system includes a frame structure having a door frame area, a passageway area, and a wall shell area. The sliding door is movable within the frame structure along a sliding axis between a closed position and an open position. The sliding door has an end face and a door leaf, and the wall shell area at least partially accommodates the sliding door in the open position. The end face points towards the passageway area and extends laterally to the sliding axis. The door leaf extends from the end face, substantially parallel to the sliding axis. An electromechanical drive unit and a control device are designed to move the sliding door. An electronic display device is also provided, disposed in defined height segments on the sliding door and connected to the control device. The display device has a user interface that extends across edges between defined areas of the end face and defined areas of the door leaf. The control device is used to manipulate the display device to display information, wherein the information is displayed on the door leaf side and / or the end face.

[0005] On the other hand, a method for operating a building sliding door system is provided. According to this method, an electronic display device for information display is controlled by a control device, causing information to be displayed on the side and / or end face of the door leaf.

[0006] The technology described herein proposes a building sliding door system in which an electronic display device, or information represented thereon, can be perceived by the user in both the closed and open positions of the sliding door. In the (fully) open position, the portion of the display device on the side of the door leaf can protrude completely or partially into and be covered by the wall shell area, while the end face of the display device remains visible and can display information there.

[0007] In one embodiment, the control device manipulates the display device based on a determined position of the sliding door, particularly based on the distance D between the end face and the door frame area. Information is displayed on the door side in the closed position, on the end face in the open position, and on the door side and / or end face in the intermediate position. For example, the information display can occur when the door is open, such that the information to be displayed (from the perspective and perception of a user standing in front of the sliding door) moves approximately fluidly from the display on the door side to the display on the door side, so that the user can perceive the information in the best way when the door is open.

[0008] In one embodiment, the information is moved to the end-face display when the distance D reaches or exceeds a predetermined threshold. The threshold can be selected based on the architecture 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 is initiated when the threshold is reached; therefore, with the threshold at approximately 80%, the information display moves only from the display on the door side to the end-face when the sliding door is already relatively wide open. Thus, the user can perceive the information even when the sliding door is substantially fully open.

[0009] Various techniques can be used to determine the position of a sliding door. In one embodiment, a rotation detector located in an electromechanical drive unit can be used to detect angular changes as the sliding door is moved by the drive unit. The control device is designed to determine the position of the sliding door based on the angular changes, specifically determining the distance D between the end face and the door frame area. In another embodiment, a sensor unit (e.g., a 3D camera) disposed on the sliding door can be used. The sensor unit is connected to the control device and determines the distance D to determine the position of the sliding door.

[0010] Depending on the type or purpose of the building or sliding door system, the display device may include at least one additional device for other functions. Therefore, in one design, the visible (multi-functional) unit can only be positioned in a single location on the sliding door for ease of installation, maintenance, and cleaning. These additional devices may, in particular, be cameras for door observer functions and / or for detecting optical codes, radio units for detecting authorization credentials and / or for communication with a user's mobile phone, speakers, proximity sensors for detecting approaching users, and / or LED lighting devices for illuminating the display device and / or the surrounding environment of the sliding door. Those skilled in the art will recognize that one or more of these devices can be positioned externally to the display device; for example, a camera may be positioned at the typical head / face height of a standing adult.

[0015] Figures 4A to 4C Showing according to Figure 1 A diagram showing the sliding door in different positions (closed, partially open, fully open). Detailed Implementation

[0016] Figure 1This is a schematic perspective view of an embodiment of a building sliding door system 1 used to separate a first building area 21 from a second building area 22. In one embodiment, the building sliding door system 1 may be part of an interior wall of a building; for example, in an apartment building, the building sliding door system may separate a private interior area of ​​an apartment (e.g., the first area 21) from a (non-private) exterior area (e.g., a corridor or stairwell) (e.g., the second area 22). Similarly, the building sliding door system 1 may be used as an interior wall of a building, such as an office building, hotel, or similar establishment; for example, in a hotel, the building sliding door system 1 may separate two adjacent rooms. In another embodiment, the building sliding door system 1 may be part of an exterior wall of a building; for example, the building sliding door system may separate an interior area (e.g., the first area 21) of a non-public building (e.g., a residential building, hotel, commercial building, or the like) from a public exterior area (e.g., a street or public square) (e.g., the second area 22). Hereinafter, the first area 21 will be referred to as interior area 21, and the second area 22 will be referred to as exterior area 22.

[0017] In the illustrated embodiment, the building sliding door system 1 includes a frame structure 2, within which different areas can be defined. For illustration and distinction, these areas are hereinafter referred to as door frame area 2a, passageway area 2b, and wall shell area 2c. The building sliding door system 1 also includes a sliding door 4, which is movable along a sliding axis x within the frame structure 2 between a closed position and an open position. In the closed position, the sliding door 4 closes passageway area 2b; in the open position, the sliding door 4 fully or partially opens passageway area 2b, allowing, for example, a person, pet, or robot to enter the corresponding other area from one of areas 21 or 22. Figure 1 In the partially open position shown, the end face 30 of the sliding door 4 is at a distance D from the door frame region 2a. Further details regarding the mechanical structure of the frame structure 2 and the sliding door 4 are given in other parts of this specification.

[0018] exist Figure 1The diagram shows that the building sliding door system 1 includes electronic and electromechanical system components and is connected to the building control system 20 (BM). In one embodiment, the building sliding door system 1 is communicatively connected to the building control system 20 (BM). As exemplary system components of the building sliding door system 1, 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. The control device 12 controls the opening and closing of the sliding door 4 and stores the current operating state of the sliding door 4 in a storage device 12a (D%) for at least a set time period. This includes information about the distance D from the end face 30 to the door frame area 2a, which can vary between zero and a maximum distance Dmax (0 ≤ D ≤ Dmax). Therefore, the control device 12 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 determined as an absolute value (length, e.g., in centimeters) or a percentage value. Examples of how to determine this distance D are given in other parts of this specification.

[0019] exist Figure 1 In the case shown, the techniques described herein can be advantageously used. Briefly and as an example, the techniques described herein enable the electronic display device 10, or the information displayed thereon, to be perceived by the user in both the open and closed positions. For this purpose, the display device 10 is arranged in defined height segments on the sliding door 4 (e.g., between approximately 1m and 1.5m). The user interface 10a of the display device 10 extends across the edge between a defined area of ​​the end face 30 and a defined area of ​​the door leaf 26 of the sliding door 4. Since the cavity in the wall shell region 2c accommodates the sliding door 4 in the (fully) open position, the door leaf side portion of the display device 10 protrudes completely or partially into and is covered by the wall shell region 2, while the end face of the display device 10 is visible and information can be displayed there. The control device 12 accordingly operates the display device 10 via electrical connection 33 to display information. In one embodiment, the control device 12 controls the display device 10 based on a determined position of the sliding door 4, particularly based on a distance D, wherein information is displayed on the door side when the sliding door 4 is closed, on the end face when open, and on the door side and / or end face in an intermediate position. For example, the information display can be performed in such a way that the information to be displayed moves in an approximately flowing manner from the display on the door side to the display on the end face, so that the user can perceive the information in the best possible way. In one embodiment, the information moves to the display on the end face when the distance D reaches or exceeds a determined threshold. Exemplarily, display options include... Figures 2A to 2CAs shown. In this specification, the terms “flow,” “move,” “press,” “flow process,” and “flow pattern” are used to describe and characterize the process, particularly from the user’s perspective and perception.

[0020] A schematic diagram of an embodiment of the display device 10 is shown in Figures 2A to 2D The electrical connection ports or lines for connection to the control device 12 are not shown; however, those skilled in the art will recognize that they exist. Those skilled in the art will also recognize that the display device 10 may include control electronics (not shown). The display device 10 is designed such that its user interface 10a extends across an edge between a defined area of ​​the end face 30 and a defined area of ​​the door leaf 26. In one embodiment, the display device 10 has an end face segment 6 and a door leaf side segment 8, which, in the illustrated embodiment, are arranged at an angle to each other, substantially at right angles. This is particularly suitable for… Figure 2D As shown in the top view, this can be two separate segments 6, 8 (individual display devices) connected to each other in or at the edge region and controlled by the control device 12 or control electronics of the display device 10 in such a way as to display information across the edge. In another embodiment, the (unique or single) curved display device may include segments 6, 8, as described elsewhere in this specification.

[0021] from Figure 2D The top view shown also reveals that segments 6 and 8 in the illustrated embodiment have different lengths (L-shaped arrangement) in both the x and y directions, with the shorter segment 6 extending along the y direction at the end face and the longer segment 8 extending along the x direction on the door side. In the z direction, segments 6 and 8 have the same length. In another embodiment, segments 6 and 8 may have equal lengths in both the x and y directions, or the end face segment 6 may be longer than the door side segment 8. In one design, segments 6 and 8 may be longer in the z direction than in both the x and y directions to achieve an edge-arranged display device 10. The dimensions of the display device 10, particularly the dimensions of segments 6 and 8, can be determined based on the type of building and / or the perimeter of the information to be displayed.

[0022] from Figures 2A to 2DThe illustrations also show that the display device 10 or its user interface 10a extends across an edge. In other words, the user interface 10a does not end at or in front of the edge between the door leaf 26 and the end face 30 on the end face or door leaf side, and then begin again on the other side, approximately as a new second user interface 10a, on that edge. Instead, the user interface 10a covers the edge, surrounds the edge, begins on one side of the edge, and continues to extend on the other side. Specifically, in one embodiment, the display device 10, bent into a single piece, includes a light-emitting diode network (also called an LED network or LED fabric) or a flexible light-emitting diode screen (LED (display) unit), particularly composed of LEDs fixed to a flexible carrier material (flexible circuit board) and then embedded in the fabric. Flexible display devices may also include organic LEDs (OLEDs), resulting in each OLED unit; the OLED units may also be designed as touch-sensitive display devices, the structure and function of which, including information regarding electronic control, are known, for example, from US2017 / 0336831A1 and WO2013 / 048881A1. In another embodiment, the display device 10 includes an LCD unit that can also be designed to span the edges.

[0023] In one embodiment, the display device 10 has a glass or plastic surface extending above the user interface 10a. The glass or plastic surface may be shaped to extend seamlessly along the curvature of segments 6, 8 and between them, as in... Figures 2A to 2D As can be seen in the illustration. To enable the information display to be perceived by the user, the glass or plastic surface is transparent to visible light. Furthermore, the glass or plastic surface can be designed such that the display device 10 can be designed as a touch-sensitive display device. In addition to these properties, the glass or plastic surface also protects the display device 10 from damage and makes it easy to clean. Methods for producing glass or plastic surfaces with the aforementioned properties are known to those skilled in the art.

[0024] In the technology described herein, the display device 10 is used to display information that informs the user, for example, about the status of the sliding door 4, its use, and / or the status of the building or the areas 21, 22 separated by the sliding door 4. The information can be represented by pictographs, symbols, and / or text; pictographs or symbols may, for example, indicate that the sliding door 4 is locked, the sliding door 4 is unlocked, certain actions are undesirable or prohibited (e.g., smoking or making a phone call), and entry is not permitted. Text, alone or in combination with pictographs or symbols, may be, for example, instructions or messages (e.g., “Please touch,” “Please wait,” “No entry,” “Do not disturb,” “Emergency exit,” “Escape route,” “Fire alarm,” or similar content) or display the user's name. Additionally, in one embodiment, an audible signal and / or a voice message corresponding to the pictograph or symbol may be triggered.

[0025] If the sliding door 4 is in the closed position, the display device 10 is operated to display information on the side segment 8 of the door leaf, such as... Figure 2A As shown. In the closed position, the end face segment 6, which is substantially covered by the door frame area 2a, is not controlled. Figure 2C In this embodiment, the sliding door 4 is in the open position, and the display device 10 is operated to display information on the end face segment 6. Between these two positions of the sliding door 4, the display device 10 is operated to display information on the end face segment 6 and / or the door leaf side segment 8, such as... Figure 2B As exemplified. In one embodiment, control is performed in such a way that when the sliding door 4 retracts into the wall shell region 2c, the user perceives the information display as if the information display were being “pushed” forward by the wall shell region 2c, as if the displayed content were standing upright while the sliding door 4 continues to move; this is exemplarily referred to as a flow mode in conjunction with the flowchart shown in FIG4. In one embodiment, this flow mode begins when a distance D reaches or exceeds a predetermined threshold; in one embodiment, this threshold 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 from the wall shell region 2c), in this embodiment, the door leaf side segment 8 remains active and displays the information. This flow process begins only shortly before the sliding door 4 is fully open. Those skilled in the art will recognize that the flow process of the information display can occur throughout the entire opening process or only near the end of the opening process. Those skilled in the art will also recognize that different thresholds can be selected depending on the type and purpose of the building or the sliding door 4. It is known to those skilled in the art that, similar to the opening process, during the closing process, the information display can move from the end face segment 6 to the door leaf side segment 8. For example, movement can begin when a threshold (80%) is reached during the shutdown process.

[0026] As described above, control of the display device 10 for displaying information or its user interface 10a is based on the determined position of the sliding door 4, particularly based on the distance D. In one embodiment, a rotation detector integrated in the drive unit 14 (motor) can be used to determine the position or distance D of the sliding door 4. Rotation detectors (also known as incremental encoders or encoders) are known to those skilled in the art; rotation detectors can be designed to detect changes in angle and direction of rotation. If the motor rotates to move the sliding door 4, each change in angle to the left or right results in a determined change in the regulating variable (e.g., the distance traveled by the sliding door increases or decreases by one (increment (+1) or decrease (-1))); if the values ​​of the closed and open positions of the sliding door 4 are known, the distance (D) can be determined based on the change in angle or the distance traveled. For example, when the sliding door 4 is put into operation via an initial run, the values ​​of the closed and open positions of the sliding door 4 can be determined.

[0027] In one embodiment, sensor unit 18 can be used to determine the position or distance D of sliding door 4. Sensor unit 18 is connected to control device 12 via electrical connection 32 and is arranged in the area of ​​end face 30 of sliding door 4. The arrangement of sensor unit 18 can be selected such that passage area 2b can be monitored and distance D can be determined. Monitoring can identify whether passage area 2b is vacant, i.e., there is neither a user nor an obstacle there, and sliding door 4 can be closed. This arrangement can be selected such that, for example, electromagnetic radiation (light or radio waves) emitted by sensor unit 18 can propagate unimpeded in the direction of passage area 2b during operation. If sensor unit 18 includes a camera for detection in the infrared or visible electromagnetic spectrum, this arrangement can be selected such that passage area 2b is within the camera's "field of view". Sensor unit 18 can be inserted, for example, into a recess on end face 30 and protected from damage and dirt by a radiation-permeable cover. To determine distance D, sensor unit 18 can also be arranged at a height such that under normal circumstances there are no obstacles or users between sensor unit 18 and door frame area 2a.

[0028] For these functions, sensor unit 18 may include one or more sensors, such as one or more sensors based on the time-of-flight (TOF) measurement principle or a 3D camera. Such a 3D camera includes, for example, a light-emitting diode or laser diode unit that emits light in the infrared range in short pulses (e.g., tens of nanoseconds). The 3D camera also includes a sensor array consisting of multiple photosensitive elements. The sensor array is connected to a processing chip (e.g., a CMOS sensor chip) that determines the propagation time of the emitted light. The processing chip can simultaneously measure the distance to multiple target points in space within milliseconds. The 3D camera may also be based on the measurement principle of recording the propagation time of emitted light by measuring the phase of the light. By comparing the phases when the light is emitted and when it is received, the elapsed time or the distance to a reflecting object is determined. For this purpose, it is preferable to emit modulated light signals rather than short light pulses. More detailed information on these measurement principles is given, for example, in the following publications: “Fast Range Imaging by CMOS Sensor Array Through Multiple Double ShortTime Integration (MDSI)”, P. Mengel et al., Technical Department, Siemens AG, Munich, Germany; and “A CMOS Photosensor Array for 3D Imaging Using Pulsed Laser”, R. Jeremias et al., IEEE International Conference on Solid State Circuits, 2001, p. 252.

[0029] In another embodiment, the functions of the sensor device 18 and the display device 10 can be combined in one device; for example, the functions of the sensor device 18 can be implemented in the display device 10, such as... Figure 2D As shown. For the function of sensor device 18, the 3D camera may be disposed, for example, on an end face below the glass or plastic surface of display device 10. In one embodiment, at least one other device for other functions may be implemented in display device 10. Figure 2DA design with multiple such devices is illustrated, showing by way of example a camera 10d for door observer function and / or for detecting optical codes (e.g., barcodes, QR codes), radio units 10b and 10c (e.g., according to RFID or Bluetooth standards) for detecting authorization credentials and / or for communication with a user's mobile phone, a speaker 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 the environment around the sliding door 4. These devices can be connected to a control device 12 via an interface device 10. Alternatively, these devices can be exclusively or additionally connected to the control device of the display device 10 so that they can be controlled and / or communicated with by the control device. The above-described devices and their functions are known to those skilled in the art, and therefore it seems unnecessary to elaborate on the implementation process at this time.

[0030] Having understood the basic system components and their functions, the following will discuss... Figure 1 Starting with the situation shown, combined with Figure 3 An exemplary method for operating a building sliding door system 1 is provided. Figure 3 The method shown begins at step S1 and ends at step S8. Those skilled in the art will recognize that the division into these steps is exemplary, and one or more of these steps may be divided into one or more sub-steps, or multiple steps may be combined into one step.

[0031] In step S2, the state of the sliding door 4 is determined. As described above, for example, the distance D from the end face 30 to the door frame region 2a can be determined by using a rotation detector. From this, the state of the sliding door 4 is determined: the sliding door 4 is closed (D=0), fully open (D=Dmax), or partially open (0<D<Dmax).

[0032] In step S3, it is checked whether the sliding door 4 is closed, i.e., D = 0. If this is the case, the process proceeds along the "yes" branch to step S5. When the sliding door 4 is closed, in step S5, information is displayed on the door side. The control device 12 accordingly operates the display device 10.

[0033] If the check in step S3 indicates that the sliding door 4 is not closed, the method proceeds along the "No" branch to step S4. In step S4, it is checked whether the sliding door 4 is fully open, i.e., D = Dmax. If this is the case, the method proceeds along the "Yes" branch to step S6. When the sliding door 4 is fully open, in step S6, information is displayed on the end face. The control device 12 accordingly manipulates the display device 10.

[0034] On the other hand, if the check in step S4 shows that the sliding door 4 is not fully open, the method proceeds along the "No" branch to step S7. Therefore, the sliding door 4 is neither closed nor fully open. In this state of the sliding door 4, information is displayed in step S7 in a flow mode (exemplarily referred to here), in which the information display moves from one segment 6, 8 to another segment 6, 8. Figure 3 In this process, the method ends in step S8.

[0035] Those skilled in the art will recognize that, for example, when a user operates the sliding door 4 to open it, the state of the sliding door 4 changes. If the sliding door 4 is subsequently fully opened, it is able to remain in the fully open position for a defined period of time before automatically closing.

[0036] See you again Figure 1 The mechanical structure of frame structure 2 and sliding door 4 will be described in further detail below. Door frame area 2a is located to the left of passageway area 2b, and door frame area 2a may also extend above passageway area 2b. Wall shell area 2c is located to the right of passageway area 2b, and wall shell area 2c may also extend above passageway area 2b. Therefore, passageway area 2b is surrounded by door frame area 2a, wall shell area 2c, building floor, or a threshold or guide rail disposed there.

[0037] Wall panels 25 facing the interior area 21 (hereinafter also referred to as interior wall panels 25), wall panels 23 facing the exterior area 22 (hereinafter also referred to as exterior wall panels 23), and lateral fasteners 17 are provided on the frame structure 2. The interior wall panels 25 are arranged substantially parallel to the exterior wall panels 23, wherein the wall panels 23, 25 specifically cover (clasp) the door frame area 2a and the wall shell area 2c and are designed to adapt to the surrounding walls. Lateral fasteners 17 are provided for connecting the building's sliding door system 1 to the building. Figure 1 The diagram shows an xyz coordinate system. 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 formed by the x-axis and z-axis. The sliding door 4 can move along the sliding axis in the x-direction. Figure 1 In the diagram shown, the sliding axis corresponds to the x-axis; therefore, the sliding axis is labeled x (sliding axis x) in this diagram.

[0038] The wall shell region 2c includes a cavity located between wall panels 23 and 25, configured to at least partially accommodate a sliding door 4 in its open position. The sliding door 4 has two substantially parallel door leaves 26 (located on the inner and outer sides of the sliding door 4, respectively) and end faces 30 pointing towards the passage region 2b and extending transversely to the sliding axis x. The door leaves extend substantially parallel to the sliding axis x from the end faces 30 and are spaced apart from each other (along the y-direction), creating an internal space between the door leaves 26 in which system components and insulation materials, for example, for sound insulation and fire resistance, are placed. Each door leaf 26 extends substantially parallel to the xz plane.

[0039] exist Figure 1 In the illustrated embodiment, the building sliding door system 1 is connected to the building control system 20 (BM) via an electrical connection 28. The building sliding door system 1 can be powered, for example, via this connection 28. In one embodiment, the supplied energy can be used to ensure the operation of the building sliding door system 1 without providing it with external control signals or commands. For example, in this embodiment, a key, access code, or other type of access authorization system component (locally) is integrated into the building sliding door system 1, enabling it to operate autonomously (in addition to electrical power).

[0040] The control device 12 is also connected to the drive unit 14 and the interface device 16 via electrical connection 34. Electrical connections 32 and 34 between the sensor unit 18 and the control device 12, and electrical connection 33 between the control device 12 and the display device 10, are distributed within the sliding door 4, for example, between the door panels 26. Electrical connections 32, 33, and 34 are designed for signal and / or energy transmission; for this purpose, the electrical connections may each comprise separate wires or electrical bus systems.

[0041] In one embodiment, the building sliding door system 1 may be provided with external control signals or control commands, such as external control signals or control commands related to checking access authorization. In this embodiment, the electrical interface device 16 is also configured for communication between the building control system 20 and the building sliding door system 1. For this purpose, the electrical connection 28 includes a communication network to which the building control system 20 and the interface device 16 are coupled. The building control system 20 may include a computer-aided building management system in which data about authorized users and objects is stored.

[0042] Those skilled in the art will recognize that the building control system 20 can be located within building 2, wherein the building control system 20 is designed as a local and externally independent unit for operating the building sliding door system 1 (or multiple such systems). In one embodiment, the functionality of the building control system 20 can be distributed to subsystems or components located locally within building 2 and remotely from building 2.

This includes, for example, storing data in a remote data center and executing programs that are not locally installed but remotely installed. Depending on the design, specific functions can be provided, for example, in control device 12 or via the “cloud.” For this purpose, for example, a software application or part of a program can be executed in the “cloud.” If needed, control device 12 then accesses the infrastructure via interface device 16 to execute the software application.

[0043] Electrical connection 28 may include an electrical bus system in the implemented system. In one embodiment, the electrical connection of the building sliding door system 1, including its power supply, is made via interface device 16. Those skilled in the art will recognize that multiple building sliding door systems 1 may exist in building 2, each of which is connected to electrical connection 28 to communicate with building control system 20, for example, in conjunction with determining and checking access authorization, in which case this process is centrally performed by building control system 20.

[0044] The following is for reference. Figures 4A to 4C Introduce the functions of building sliding door system 1. Figures 4A to 4C Each of these figures shows a schematic horizontal cross-sectional view of an embodiment of a building sliding door system 1 having a sliding door 4. In each of these figures, the components included in the sliding door 4 are a sensor unit 18(S), a control device 12(DC), a display device 10, and a drive device 14(M); for illustrative purposes, 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, particularly between the door panels 26.

[0045] The illustrated embodiment of the building sliding door system 1 is based on a principle similar to that known from EP28166241A1. 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. In relation to the building sliding door system 1 according to the technology described herein, it is shown that the two door panels 26 have a door panel distance d1 in the closed position of the sliding door 4. During the opening of the sliding door 4, the two door panels 26 are moved by the actuator 9 (… Figures 4A to 4CThe two door panels are moved toward each other to such an extent that the two door panels have a door panel distance d2, which is set such that the sliding door 4 is in the fully or partially open position ( Figure 4B and Figure 4C The door has a sufficiently small thickness to fit into the receiving structure of the wall shell region 2c. The door leaf distance d1 is greater than the door leaf distance d2. When the sliding door 4 is pushed out of the wall shell region 2c, the two door leaves 26 move away from each other (unfold), so that the sliding door 4 is in the closed state ( Figure 4A The thickness is defined such that the outer sides of the two door panels 26 in the closed position are substantially flush with the outer sides of the wall shell area 2c or its cladding (wall panels 23, 25). Thus, there are substantially smooth finishes on both sides of the wall in the door area.

[0046] In one embodiment, the building sliding door system 1 has a guide on the door lintel that carries the sliding door 4 and guides it along a path between its closed and open positions. The sliding door 4 has a complementary device on its upper edge. When the drive unit 14 moves the sliding door 4 and acts on the complementary device, for example, the guide and the complementary device cooperate. The guide and the complementary device form, for example, a roller mechanism (e.g., a roller bearing slide system (roller slide)). The drive unit 14 may include, for example, a motor or a pneumatic sliding actuator that acts on, for example, the sliding door 4. Those skilled in the art will appreciate that this design is not limited to a roller mechanism, and that the guide and the complementary device can be designed in different ways, for example, as telescopic devices.

[0047] In one embodiment, the two door panels 26 move toward or away from each other via an actuator 9. The actuator 9 may include a mechanically, electrically, or electromechanically activated deployment device. The deployment device is designed to move the door panels 26 toward each other when the sliding door 4 is to be opened, and to move the door panels 26 away from each other when the sliding door 4 is to be closed. Those skilled in the art will appreciate that alternative deployment devices, such as cylinders operated by a pressure medium, may also be provided.
