[0003] BUILDING EQUIPMENT FOR ELEVATOR-SERVED FLOOR

[0004] Description

[0005] The technology described here generally relates to the technical equipment of a building. Exemplary embodiments of the technology relate to the technical building equipment on a floor served by an elevator system, in particular a building system with an elevator system and a method for operating such a building system.

[0006] A multi-story building, starting at a certain number of floors, is typically equipped with an elevator system in addition to a stairwell, serving the individual floors. In such a building, which may contain apartments and / or office / commercial spaces, the top floor may be more attractive to some user groups than a lower floor, for example, due to the view, exclusivity, and / or lower noise levels. Such an apartment is also known as a penthouse. A penthouse occupant can reach their floor by elevator or via the stairwell. To access the penthouse floor by elevator or stairwell, the occupant usually needs to possess authorization (e.g., an electronic or physical key).

[0007] In the event of a fire, an elevator shaft can, under certain circumstances, contribute to fire spread due to the chimney effect. Furthermore, elevator shafts transmit noise effectively vertically, which can then be heard on the floors below because the shaft doors of the elevator system are not optimized for sound insulation. Particularly for these reasons, and also for the (personal) safety interests of the occupants, there is usually a vestibule in front of the actual penthouse apartment or apartment door, providing access to the elevator and stairwell. However, this vestibule is an unused space for residential purposes. Therefore, there is a need for a technology that resolves the conflict between fire and noise protection requirements and safety interests on the one hand, and the desire for better space utilization on the other.

[0008] One aspect of the technology concerns a building system with an elevator system and 2024P00085WÖ

[0009] - 2 - a building sliding door system. The elevator system comprises an elevator control unit and an elevator car with a car door. The elevator car travels in an elevator shaft between floors of a building. The elevator shaft has a shaft door on each floor, located on a shaft wall, which can be coupled to the car door for opening and closing. The building sliding door system defines an access-restricted zone in the direction of the elevator system, is communicatively connected to the elevator system, and has a frame structure installed in a building wall, a sliding door, an electromechanical drive unit, and a control unit on each floor. The electromechanical drive unit and the control unit are designed to move the sliding door within the frame structure between a closed position and an open position.The building sliding door system is designed to receive a control signal generated by the elevator system via the communicative link, indicating the opening or closing of the cabin door and the shaft door, and to control the sliding door according to the control signal when the control signal indicates the opening or closing of the cabin door and the shaft door, and to open or close the sliding door according to the control signal.

[0010] Another aspect concerns a procedure for operating the building system. A control signal from the elevator system is received by the building's sliding door system. The status of the sliding door is then determined. This status indicates whether the sliding door is closed or open. If the sliding door is open and the control signal is received, the electromechanical drive unit of the building's sliding door system is activated to close the door. If the sliding door is closed and the control signal is received, the electromechanical drive unit of the building's sliding door system is activated to open the door.

[0011] The technology described here creates a building system that considers fire and noise protection requirements, security interests, and space utilization. The building sliding door system is designed with fire protection, sound insulation, thermal insulation, and burglar resistance in mind, possessing properties that at least match those of a conventional building or apartment entrance door. Therefore, a vestibule is no longer necessary, or the vestibule can be significantly smaller. This prevents a person from having to deal with a 2024P00085WÖ

[0012] - 3 -

[0013] If someone has to handle keys (apartment keys) or similar items, or wait until the apartment door is opened, the sliding door will be activated to open, for example, when the cabin door and the shaft door open.

[0014] The technology described here offers additional degrees of freedom in the planning of the penthouse apartment or the penthouse apartment itself, with regard to the aforementioned room usage. The elevator system and the building's sliding door system remain two independent systems that are interconnected. The elevator system continues to meet the safety requirements specified in elevator standards (e.g., the car door and shaft doors remain unchanged, and their operation is controlled and monitored in the usual manner); this applies analogously to the building's sliding door system (e.g., it remains ensured that only authorized persons have access and that fire and burglar protection is in place). Within the building system, the elevator system and the building's sliding door system, in combination, enable these additional degrees of freedom and offer enhanced comfort for occupants.

[0015] The additional degrees of freedom arise particularly with regard to the arrangement of the building's sliding door system, with or without a vestibule. The frame structure of the building's sliding door system comprises a passage area, a door frame area, and a wall panel area. In one embodiment, the passage area can be located directly opposite the shaft door. From both the elevator car and the apartment door, the person has a direct view of the open door. This is also the case in another embodiment, according to which the passage area is directly adjacent to the shaft door; in this case, there is also only one door from the person's perspective. Since there is no vestibule in this embodiment, the living space can be optimized.

[0016] In one embodiment, the sliding door opens essentially synchronously with the cabin door and the shaft door, allowing the person to walk directly from the elevator through the already open door. This ensures that, from the person's perspective, there is only one door. Furthermore, the person can move seamlessly, without delay, from the elevator into the access-restricted area (apartment) and from the apartment into the elevator. 2024P00085WÖ

[0017] - 4 -

[0018] In one embodiment, the building's sliding door system is designed to send an elevator call signal to the elevator system via a communication link. This elevator call signal indicates that the elevator car has been requested at the floor of the building's sliding door system. For example, if a person wishes to leave the access-restricted zone (apartment) through the building's sliding door system, they can initiate the opening of the sliding door (e.g., by pressing or touching a control device); the elevator call signal is then generated, in particular without any further action required from the person. Once the elevator car is at the floor, the sliding door is activated according to the control signal to open it. The sliding door therefore opens when the elevator car is ready for boarding. Instead of entering a separate elevator call, it is sufficient for the person to initiate the opening of the sliding door.

[0019] In one embodiment, the building system is designed to verify a person's authorization for the restricted access zone before they travel in the elevator car to the floor of the building's sliding door system. The control signal generated by the elevator system indicates valid authorization, so the building's sliding door system only activates the sliding door to open it if the authorization is valid according to the control signal. The person wishing to travel to the floor must not only be authorized to do so, but also to open the sliding door and enter the restricted access zone. For example, a service technician for elevator maintenance can travel to the floor, e.g., to service the landing door, but they are not authorized to enter the restricted access zone; in this example, the sliding door remains closed.If a person wishes to enter the restricted area via the elevator system, such access control ensures that the sliding door is only opened if the person is authorized to access it.

[0020] The following section explains various aspects of the improved technology in more detail using exemplary embodiments in conjunction with the figures. In the figures, identical elements have the same reference numerals. Figure 2024P00085WÖ shows:

[0023] Fig. 2 shows a schematic front view of the building's sliding door system;

[0024] Fig. 3 shows a schematic representation of a horizontal cross-section through the building's sliding door system, a shaft door and a cabin door;

[0025] Figs. 4A-4C schematic representations of the building sliding door system according to Fig. 1 in different positions (closed position, partially open position, fully open position); and

[0026] Fig. 5 shows a flowchart of an exemplary embodiment of a method for operating the building system.

[0027] Fig. 1 is a schematic representation of a building with a building system 1, which includes an elevator system 10 and a building sliding door system 2. The elevator system 10 and the building sliding door system 2 are two independent systems that can communicate with each other. A building entrance 28 can, for example, open onto a ground floor L into an entrance hall in which an elevator control terminal 26 of the elevator system 10 is located and from which there is access to an elevator car 12. The building has at least one access-restricted zone Z; this zone Z can be, for example, an apartment or an office or commercial space. Depending on the building, it can have a number of access-restricted zones, in particular apartments. In the situation shown in Fig. 1, the access-restricted zone is located on a floor ATT above the ground floor L.The access-restricted zone Z is, in the following, an apartment, in particular a penthouse apartment belonging to person P; the building's sliding door system 2 separates the access-restricted zone Z from the elevator system 10. The elevator system 10 serves the penthouse apartment; in addition, the penthouse apartment can be accessed and exited via a stairwell 8, particularly when the elevator system 10 is unavailable, e.g., during maintenance or in case of fire.

[0028] The elevator system 10 shown in Fig. 1 comprises, in the illustrated embodiment, an elevator control unit (EC) 14, a drive unit (M) 16, and an elevator car 12 with a car door 12a. Those skilled in the art will recognize that the elevator system 10 comprises further components. The components of the elevator system 10 and its 2024P00085WÖ

[0029] - 6 -

[0030] The operating principles are generally known to those skilled in the art, so more detailed explanations are only provided to the extent necessary for a better understanding of the technology described here. For example, the elevator control unit 14 processes a received elevator call and accordingly controls the drive unit 16 to move the elevator car 12 in a vertical shaft 20. A shaft door 20a, 20b is located on each floor L, ATT, separating the shaft 20 from the respective floor L, ATT. The car door 12, controlled by a door control unit (DC) 18, can be coupled to the shaft door 20a, 20b on each floor L, ATT for closing and opening movements. The door control unit 18 is connected to a car control unit 22, which is connected to the elevator control unit 14.

[0031] The building sliding door system 2 is arranged on floor ATT of the penthouse apartment in Fig. 1; the penthouse apartment essentially occupies floor ATT and therefore constitutes the access-restricted zone Z. A schematic front view of the building sliding door system 2 from the perspective of the penthouse apartment is shown in Fig. 2. The building sliding door system 2 comprises a frame structure 2a (shown in Fig. 2 without cladding), a sliding door 4 arranged therein, and an operating device 6. Different areas are defined in the frame structure 2a. For illustration and differentiation, these areas are referred to below as door frame area 2d, passage area 2b, and wall panel area 2c. The sliding door 4 is movable within the frame structure 2a between a closed position and an open position along a horizontal sliding axis.In the closed position, the sliding door 4 closes off the passageway 2b, and in the open position, the sliding door 4 fully or partially opens the passageway 2b, allowing, for example, person P to pass through. The wall panel area 2c fully or partially accommodates the sliding door 4 in the open position.

[0032] Using the control unit 6, person P in the penthouse apartment can send a control command to open the sliding door 4 to a control unit of the building's sliding door system 2. Person P can make a manual input at the control unit 6, or person P can operate a radio device 5 (e.g., a mobile phone) or send a command to the (radio-communication-equipped) 2024P00085WÖ

[0033] - 7 -

[0034] Hold the operating device 6 to initiate the control command. The control device controls the opening and closing of the sliding door 4. In one embodiment, the building sliding door system 2 is communicatively connected to the elevator system 10; for illustration, this is indicated in Fig. 1 by an interface device (IF) 30. The interface device 30 can be configured for wired and / or wireless communication; wireless communication can, for example, be based on WiFi / WLAN radio technology. The building sliding door system 2, or its operating device 6, can be communicatively connected to a door intercom system. Further details of the building sliding door system 2 are given elsewhere in this description.

[0035] In the building system 1 shown in Fig. 1, the technology described here can be advantageously applied to resolve the aforementioned conflict between fire and noise protection requirements and security interests on the one hand, and the interest in better space utilization on the other. The building sliding door system 2 is designed with regard to fire protection, sound insulation, thermal insulation, and burglar resistance such that it possesses properties that at least correspond to those of a conventional building or apartment entrance door. The building system 1 is designed such that, for example, if person P is in the penthouse apartment, a control command to open the sliding door 4 also triggers an elevator call signal, thereby requesting the elevator car 12 to floor ATT.Depending on the configuration of building system 1, the control command can be transmitted from the building sliding door system 2 to the elevator system 10, which is communicatively connected to it, or a control command entered on a mobile phone to open the sliding door 4 is transmitted to the elevator system 10 via a communication network (mobile network). When the elevator car 12 arrives at floor ATT, the correspondingly controlled car door 12a engages with the floor door 20a, thereby opening both the car door 12a and the shaft door 20a. In one embodiment, the building sliding door system 2 is controlled essentially simultaneously to open the sliding door 4. In another embodiment, the control can originate from the elevator system 10, which signals to the building sliding door system 2 that the elevator car 12 is arriving or has arrived at floor ATT.In another embodiment, the control can originate from a sensor device that detects the presence of the 2024P00085WÖ.

[0036] - 8 -

[0037] The elevator car 12 on floor ATT is detected. Person P can then leave the penthouse apartment through the open sliding door 4 and enter the elevator car 12, which is ready with the elevator doors open (shaft door 20a, car door 12a).

[0038] According to the technology described here, in one embodiment the building sliding door system 2 can be arranged separated from the shaft door 20a by an anteroom. In another embodiment, the building sliding door system 2 can be arranged directly opposite the shaft door 20a; here too, an anteroom can be present. In this embodiment, a vertical plane of the sliding door 4 is essentially parallel to a vertical plane of the shaft door 20a. Upon leaving the penthouse apartment, person P then sees the elevator car 12, ready for boarding, directly in front of them.

[0039] In the embodiment shown in Fig. 1, the building sliding door system 2 is arranged on a building wall where the shaft door 20a is also located; the frame structure 2a of the building sliding door system 2 can, for example, be attached to a shaft wall and / or to the adjoining building wall. The building sliding door system 2 can be considered to be arranged directly on the shaft door 2a. In such an arrangement, the sliding door 4 and the shaft door 20a are arranged parallel to each other and directly opposite each other, separated only by a small gap (e.g., due to the design of the sliding door 4 and / or the shaft door 20a). In this embodiment, there is no vestibule; instead, person P moves directly from the penthouse apartment into the elevator car 12, or from the elevator car 12 directly into the penthouse apartment. From person P's perspective, there is only one door. Since there is no vestibule, the living space in the penthouse apartment is optimized.The requirements for access control, fire protection, sound insulation, thermal insulation, and burglar resistance for the penthouse apartment floor and / or the penthouse apartment itself are met, among other things, by the building's sliding door system 2. Furthermore, the building's sliding door system 2 is designed as a so-called "wallpaper door," which can be customized for the penthouse apartment according to a choice of materials, colors, and designs—something that is generally not possible with a shaft door. In addition to the building's sliding door system 2, a door, such as a swing door, is installed on the penthouse floor (e.g., in the penthouse apartment) providing access to the penthouse apartment (2024P00085WÖ).

[0040] - 9 - to stairwell 8 is made possible and is designed accordingly with regard to safety and design.

[0041] The minimum distance between the sliding door 4 and the shaft door 20a is also shown in Fig. 3. Fig. 3 shows a schematic representation of a horizontal cross-section through the building sliding door system 2, the shaft door 20a, and the car door 12a. The building sliding door system 2 is arranged parallel to the shaft wall and the shaft door 20a; the shaft wall is indicated by a dashed line. The elevator car 12 and the connection between the door control unit 12 and the elevator control unit 14 via the car control unit 22 are shown schematically in Fig. 3 for illustration purposes.

[0042] Figure 3 also shows the aforementioned options for controlling the building sliding door system 2. In one embodiment, the control can originate from the elevator system 10, which transmits a signal to the building sliding door system 2 indicating that the elevator car 12 is arriving or has arrived at floor ATT; this is indicated by a broken line. In another embodiment, the control can originate from a sensor device 21 located on floor ATT, which detects the presence of the elevator car 12 on floor ATT; this is also indicated by a broken line. The sensor device 21 can include an electromechanical switch that is activated by the elevator car 12 upon its arrival or presence on floor ATT.Alternatively or additionally, the electromechanical switch device can detect the unlocking and / or movement of the shaft door 20b and thereby be activated. Upon activation, the sensor device 21 generates a sensor signal to control the building sliding door system 2. The building sliding door system 2 has an interface device to receive the sensor signal or the signal from the elevator system 10.

[0043] The following describes the operation of an embodiment of the building sliding door system 2 with reference to Figures 4A to 4C. Figures 4A to 4C each show a schematic representation of a horizontal cross-section of an embodiment of the building sliding door system 2 with the sliding door 4. In 2024P00085WÖ

[0044] - 10 - In each of these illustrations, the following components encompassed by the sliding door 4 are shown: a control unit 36 ​​(DC), a drive unit 32 (M), the operating unit 6, and a sensor unit 38; for illustrative purposes, further electrical connections to a door intercom system and a power supply are not shown. The sliding door 4 can comprise a (single) door leaf or two door leaves 34 arranged parallel to each other. The drive unit 32 and the control unit 36 ​​are arranged within the sliding door 4, in one embodiment in particular between the two door leaves 34. The control unit 36 ​​is connected to the aforementioned interface unit 30, which—depending on the embodiment—receives the signal from the elevator system 10 or the control signal from the control unit 21.

[0045] The building sliding door system 2 is described below with reference to a sliding door 4 with two door leaves 34, but is not limited to this. The illustrated embodiment of the building sliding door system 2 is based on a principle similar to one known from EP 2 876 241 A1. This patent describes a sliding door system in which two opposing door surfaces are coupled to an actuator that moves the door surfaces towards or away from each other. With reference to the building sliding door system 2 according to the technology described here, this means that the two door leaves 34 have a leaf gap dl when the sliding door 4 is in the closed position. During the opening of the sliding door 4, the two door leaves 34 are moved towards each other by an actuator 44 (Fig. 4A - Fig. 4C) so that they have a leaf gap d2 which is dimensioned so that the sliding door 4 is in its fully or partially open position (Fig. 4B and Fig. 4C).4C) has such a small thickness that it fits into the receiving structure of the wall panel area 2c. The leaf spacing dl is greater than the leaf spacing d2. When the sliding door 4 is pushed out of the wall panel area 2c, the two door leaves 26 are moved away from each other (spread apart) so that the sliding door 4 has a defined thickness in the closed state (Fig. 4A). The thickness is defined such that the outer surfaces of the two door leaves 34, in the closed position, are essentially flush with the outer surfaces of the wall panel area 2c, or its cladding. This results in an essentially smooth surface finish on both sides of the wall in the door area. 2024P00085WÖ.

[0046] - 11 -

[0047] With an understanding of the principal system components and their functionalities described above, an exemplary method for operating the building system 1 is described below in conjunction with Fig. 5, starting from the situation shown in Fig. 1. The method shown in Fig. 5 begins in step S1 and ends in step S7. Those 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.

[0048] In step S2, a control signal from elevator system 10 is received by the building sliding door system 2. Elevator system 10 generates the control signal when, following an elevator call from person P, it operates floor ATT (e.g., a journey of elevator car 12 to or from floor ATT), where the building sliding door system 2 is located, and the car door 12a and / or the shaft door 20a are to be activated. The control signal thus indicates the activation of car door 12a and / or the shaft door 20a.

[0049] In step S3, the status of sliding door 4 of the building sliding door system 2 is determined. The status indicates whether sliding door 4 is closed or open. For example, sliding door 4 is closed when traveling to floor ATT (before the arrival of elevator car 12), and open when traveling from floor ATT (after person P has entered elevator car 12).

[0050] If step S4 shows that the sliding door 4 is open, the process proceeds along the "yes" branch to step S5. In step S5, with the sliding door 4 open and the control signal received, the electromechanical drive unit 32 of the building sliding door system 2 is activated to close the sliding door 4.

[0051] If step S4 shows that sliding door 4 is not open, the process proceeds along the "no" branch to step S6. In step S6, if sliding door 4 is not open and the control signal is received, the electromechanical drive unit 32 of the building sliding door system 2 is activated to open sliding door 4. 2024P00085WÖ

[0052] - 12 -

[0053] In both steps S5 and S6, the sliding door 4 moves essentially synchronously with the cabin door 12a and the shaft door 20a. Therefore, the sliding door 4 is only open when the elevator car 12, with its cabin door 12 and shaft door 20a open, is on floor ATT. Otherwise, the sliding door 4 is closed; in this case, the penthouse apartment can be accessed via stairwell 8. The procedure ends in step S7.

[0054] In one embodiment, building system 1 can check whether person P is authorized to travel to floor ATT to enter the access-restricted zone Z. For this purpose, an access control function can be implemented in building system 1, which is configured accordingly. For example, a reader configured to capture an authorization certificate can be located on floor L. The reader or its function can be implemented in the elevator control terminal 26. An authorization certificate is typically assigned to a person or group of people in building system 1 (e.g., in a user profile database) and must be presented by the person, for example, to use elevator system 10. The authorization certificate can be stored as a password (code) on an information carrier (e.g., a USB drive).in a chip of a smart card, a magnetic stripe of a magnetic stripe card, or the memory of a mobile phone) or represented (e.g., as an optical code in the form of a QR code, a barcode, or a color code). For a person, the proof of authorization can, in one embodiment, be a biometric characteristic, e.g., a fingerprint pattern or a facial pattern.

[0055] The elevator control terminal 26 can be adapted to the authorization credential(s) used in the building. In one embodiment, the elevator control terminal 26 can have an optical reading device (e.g., a digital camera) to capture, for example, an optical code from an information carrier. The information carrier can be, for example, in the form of a credit card-sized employee ID card or similar; in another embodiment, a mobile phone (or a similar electronic device) serves as the information carrier for the person displaying the optical code on a screen. In one embodiment, the digital camera can be used to capture a biometric 2024P00085WÖ

[0056] - 13 -

[0057] The biometric authorization can be used. The captured biometric authorization can then be used in conjunction with a recognition device and stored biometric data of persons registered in the building to determine access authorization, e.g., by means of facial recognition.

[0058] Additionally or alternatively, the elevator control terminal 26 can include a radio-based reader that reads the authorization certificate, for example, from a chip of an RFID transponder. An employee ID card, a mobile phone, or similar device can serve as the RFID transponder. In one embodiment, the radio-based reader can be configured to communicate with the mobile phone or the RLID device using near-field communication (NEC) or Bluetooth technology. In one example, the mobile phone transmits the (electronic) authorization certificate to the radio-based reader using Bluetooth technology as soon as the mobile phone is within radio range of the reader.

[0059] The control signal received in step S2 indicates whether the authorization certificate, recorded, for example, on floor L, is valid and whether the person is authorized to access the restricted zone Z. If the authorization is valid, the building's sliding door system 2 controls sliding door 4 according to the control signal to open it. The person wishing to travel to floor ATT must therefore not only be authorized to do so, but also to open sliding door 4 and enter the restricted zone Z. If there is no authorization to access the restricted zone Z, sliding door 4 will not open.

[0060] Referring again to Figures 1 and 2, further details of the building system are described below. Interior wall panels facing the penthouse apartment are arranged on the frame structure 2. These panels cover (cladding) the wall shell area 2c and can be aesthetically adapted to the surrounding wall. The wall shell area 2c comprises a cavity between the interior wall panels and an exterior wall, dimensioned to at least partially support the sliding door 4 in the open position. The sliding door 4 has two essentially parallel door leaves (one on the inside and one on the outside of the sliding door 4). 2024P00085WÖ

[0061] - 14 -

[0062] The door leaves are spaced apart, creating an interior space between them where system components and insulation material, e.g. for sound and fire protection, can be placed.

[0063] A person skilled in the art recognizes that essentially all components and functions of the building system can be located within the building, with the building system 1 being designed as a local unit independent of any external system. In one embodiment, functions of the building system 1 can be distributed across subsystems or components located both locally within and remotely from the building. The subsystem located within the building can be connected to an IT infrastructure for so-called cloud computing (colloquially also referred to as "the 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, within the building or via the "cloud."For example, a software application or parts thereof can be run in the "cloud". A control unit then accesses this infrastructure via an interface as needed to execute the software application.
