Description

Technical Field

[0001] The technologies described herein generally relate to building equipment. Embodiments of this technology particularly relate to building equipment for separating entrances to a building or its interior, and to a method for operating such 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, this separation is typically achieved through doors. For example, it is known that when constructing building walls made of brick, concrete, and / or drywall (e.g., wood and / or metal structures combined with gypsum board), door frames (frames) are installed at designated locations and doors are installed within them. These doors can be designed as sliding doors with movable door panels, rotatably fixed to the door frame (frame, doorway) by two or more hinges (door hinges), or as folding doors, where one or more door panels are divided into multiple sections by hinged straps or articulated flexible strips, unrolling from the closing plane when opened. Sliding doors are also known, which are fixed to a frame via a running track, with the door panels suspended or inserted into the frame and capable of lateral movement.

[0003] For example, EP2876241A1 describes a sliding door that can be moved between a closed position and an open position in 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. One or more seals on the sliding door seal it to prevent noise, smoke, and fire. Despite such sealing, this may not be sufficient for buildings with higher requirements for protection against noise, smoke, and fire. Therefore, a technology is needed that can meet one or more of these requirements.

[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 passageway area and a wall shell area, and a sliding door that can move between a closed position and an open position within the frame structure, in which the wall shell area at least partially accommodates the sliding door. The building sliding door system also has an electromechanical drive unit and control device designed to control the movement of the sliding door. Additionally, the building sliding door system includes a fire-resistant unit having a control console and a fire-resistant device movably supported on the control console, the fire-resistant device being made of a material with defined fire resistance properties. The fire-resistant device can move horizontally within the wall shell area in relation to the control console between a retracted position and an extended position, in which the sliding door is in the open position and in the extended position is in the closed position. Summary of the Invention

[0005] The technology described herein proposes a building sliding door system with additional fire protection measures. These measures are located in the wall shell area and are particularly effective when the sliding door is in the fully closed position. This means that although the cavity used to house the sliding door cannot be filled with soundproofing or fire-resistant materials, sufficient fire resistance is still provided within the cavity of the wall shell area.

[0006] The fire-resistant device is designed to create an effective fire-resistant surface at least equivalent to the vertical surface provided in the wall shell area for accommodating the sliding door. The fire-resistant device can be configured such that it is equal to or larger than the area occupied by the sliding door in its open position.

[0007] Fire-resistant units can be designed in different ways. One type is a passive fire-resistant unit, where the fire-resistant device can move horizontally along with a sliding door. In one embodiment, the sliding door is connected to the fire-resistant device, wherein the sliding door, when closed, actuates the fire-resistant device and pushes it into an extended position. In another embodiment, when the sliding door is opened, it can also carry the fire-resistant device and push it into a retracted position. In yet another embodiment, controlling the sliding door is sufficient, and the sliding door then acts on the fire-resistant device.

[0008] According to one embodiment, the fire-resistant unit can be designed as an active fire-resistant unit. Here, when the sliding door is in the closed position, the fire-resistant device can extend horizontally independently of the sliding door. In one embodiment, the fire-resistant unit has an electromechanical drive unit connected to a control device and / or interface device. As an active fire-resistant device, the fire-resistant unit can be selectively activated and extended or retracted, for example, at a set time or in the event of a fire alarm in the building.

[0009] In one embodiment, the control console is mounted on a frame structure. In another embodiment, the control console is designed to be fixed to a building wall. Those skilled in the art will know that the control console can also be fixed to both a frame structure and a building wall. Therefore, the structure of the control console can be selected based on the construction and design of the fire-resistant unit.

[0010] The movement method of the sliding door and the fire-resistant device can also be selected. In one embodiment, an upper guide rail is provided on the frame structure, and the sliding door has a roller mechanism by means of which the sliding door can be pushed along the upper guide rail. If a roller mechanism is used on the sliding door, the fire-resistant device can be connected to the roller mechanism of the sliding door and moved along the upper guide rail via the roller mechanism. In another embodiment, a sliding mechanism can be provided instead of a roller mechanism; here, the aforementioned connection scheme can also be provided so that the fire-resistant device can be movably arranged on the upper guide rail.

[0011] In one embodiment, the fire-resistant device is vertically guided through a channel on the lower side of the upper guide rail and is movable along the channel. In another embodiment, the fire-resistant device is movable along the outer long side of the upper guide rail. These structural options allow the fire-resistant device to move in a (controlled) guided manner on or very close to the guide rail. Additionally, this creates the possibility of guiding the fire-resistant device upwards as much as possible within the frame structure, such that the fire-resistant device at least covers the vertical surface of the wall shell area and, depending on the dimensions, extends beyond that vertical surface. This achieves optimal fire and smoke sealing.

[0012] Sliding doors arranged in a building sliding door system can be designed in different ways. In one embodiment, the sliding door has an inner door leaf, an outer door leaf, and an actuator designed to move the two door leaves toward each other during the opening movement of the sliding door, wherein the thickness of the sliding door to be accommodated is reduced so as to be accommodated by the wall shell area, and during the closing movement, the two door leaves are moved away from each other, thereby increasing the thickness of the sliding door. The technology described herein can be used in conjunction with such sliding doors; however, the technology can also be used in conjunction with sliding doors in which the thickness of the sliding door remains unchanged.

[0013] In one embodiment, fire protection measures in a building sliding door system are supplemented by the placement of fire-resistant and / or sound-insulating materials between the door panels, the fire-resistant and / or sound-insulating materials being selected according to building-specific regulations.

[0023] Figure 1 This 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, where it can separate a private interior area of ​​an apartment (e.g., the first building area 21) from a (non-private) exterior area (e.g., a corridor or stairwell) (e.g., the second building area 22). Similarly, the building sliding door system 1 may be used, for example, in the interior walls of office buildings, hotels, etc.; in a hotel, it may, for example, 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, covering the interior area of ​​a non-public building (e.g., a residential building, hotel, commercial building, etc.) from a public exterior area (e.g., a street or public square) (e.g., the second building area 22). Hereinafter, the first building area 21 will be referred to as the interior area, and the second building area 22 as the exterior area.

[0024] In the illustrated embodiment, the building sliding door system 1 includes a frame structure 2 within which different areas can be fixed. For illustration and distinction, these areas are hereinafter referred to as door frame area 2a, passageway area 2b, and wall shell area 2c. Figure 1 In this configuration, door frame area 2a is located to the left of passageway area 2b, and the door frame area may also extend over passageway area 2b. Wall shell area 2c is located to the right of passageway area 2b, and therefore, this wall shell area may also extend over passageway area 2b. Thus, passageway area 2b is surrounded by door frame area 2a, wall shell area 2c, and building floor or thresholds or guide rails arranged there.

[0025] Wall panels 25 facing the interior area (hereinafter also referred to as inner wall panels 25), wall panels 23 facing the exterior area (hereinafter also referred to as outer wall panels 23), and lateral fasteners 17 are arranged on the frame structure 2. The inner wall panels 25 are arranged substantially parallel to the outer wall panels 23. The wall panels 23 and 25 specifically cover (clad) the door frame area 2a and the wall shell area 2c, and are designed to conform to the surrounding walls. Lateral fasteners 17 are provided for connecting the building's sliding door system 1 to the building. Relative to... Figure 1 The building sliding door system 1 is shown in the xyz coordinate system. It has a length L in the x direction, a depth T in the y direction, and a height H in the z direction. The building sliding door system 1 extends in a plane supported by the x-axis and z-axis.

[0026] The building sliding door system 1 also includes a sliding door 4, which is movable within the frame structure 2 between a closed position and an open position. In the closed position, the sliding door 4 closes the passageway area 2b, while in the open position, the sliding door 4 fully or partially opens the passageway area 2b, allowing, for example, a person, pet, or robot to move from one of the building areas 21, 22 to a corresponding other area. The wall shell area 2c includes a cavity located between wall panels 23, 25, the size of which is set such that the cavity at least partially accommodates the sliding door 4 in the open position.

[0027] Figure 2 This is also a schematic perspective view of an embodiment of the building sliding door system 1, wherein, exemplarily, the sliding door 4 is shown in a middle position, in which the sliding door 4 is partially open and the passage area 2b is partially open. Figure 2 The diagram shows that the building sliding door system 1 includes electronic and electromechanical components and is connected to the building control system 20 (BM). The building control system 20 can be connected to a fire alarm system. Additionally, in... Figure 2 The wall panel 25 has been removed to show the fire-resistant unit 6 arranged in the building's sliding door system 1. Figure 1 In the diagram, fire protection unit 6 is drawn with a dashed line because, in the illustrated embodiment, the fire protection unit is not visible from the outside behind the wall panel 25.

[0028] Fire protection unit 6 includes a control console 8 and a fire-resistant device 10, which is designed to form a fire and smoke barrier in the wall shell area 2c of the building sliding door system 1. This barrier exists specifically when the sliding door 4 is in the closed position and the fire-resistant device 10 forms an effective fire-resistant surface. In one embodiment, the effective fire-resistant surface extends parallel to the xz plane, and the dimensions of this surface at least correspond to the vertical surface of the wall shell area 2c; this is as follows: Figure 1 As shown. Figure 2In this configuration, the sliding door 4 is slightly open, resulting in a relatively small effective fire-resistant area for the fire-resistant device 10. In this case, the portions of the fire-resistant device 10 and the sliding door 4 located within the wall shell region 2c provide fire resistance. In one embodiment, the size of the fire-resistant surface of the fire-resistant device 10 is selected such that the fire-resistant device extends beyond the vertical surface of the wall shell region 2c, thereby achieving the best possible fire and smoke seal. Embodiments of the fire-resistant device 10 are given elsewhere in this specification.

[0029] exist Figure 1 and Figure 2 In the case shown, the techniques described herein can be advantageously used. Simply and as an example, the techniques described herein enable the installation of fire-resistant measures within the cavity of the wall shell region 2c, particularly when the sliding door 4 is in the fully closed position. Since the cavity is designed to accommodate the sliding door 4 when it is open, the cavity cannot be filled with sound-insulating or fire-resistant materials, which may be desirable depending on the purpose of the building and / or the building's sliding door system 1. According to the techniques described herein, the fire-resistant measures consist of: a fire-resistant unit 6 in the wall shell region 2c, the fire-resistant device 10 of which can extend and retract horizontally relative to a fixed control panel 8, so as to fill at least one vertical surface of the wall shell region 2c with the formed effective fire-resistant surface, which in its current position does not cover the sliding door 4. Fire protection unit 6 (or its fire protection device 10) may be designed, for example, in the form of a roller shutter or (vertical) barrier or a folding mechanism, wherein the vertical (proximal) side arranged on or near the control panel 8 is substantially fixed in position (it may be fixed to the control panel 8, for example), and is designed with a vertical (far) side opposite to the control panel 8 that moves with the sliding door 4, thus allowing the fire protection device 10 to extend and retract in the horizontal direction.

[0030] Fire protection device 10 is composed wholly or partially of a material having defined or specific fire-resistant properties. In the field of fire protection, the fire resistance (also known as fire toughness) of a material indicates how long the material maintains its function under standard fire conditions. This material can be, for example, textiles, made from flame-retardant synthetic fibers, glass fibers, or a combination of synthetic and glass fibers. The material can also be a construction of flexible, connected metal and / or plastic elements, or a combination of these elements with textiles. Those skilled in the art are familiar with fire-resistant materials suitable for fire protection in the form of barriers or fire curtains; for example, fire curtains from SIMON PROtec Systems AG of Switzerland. Therefore, further description is unnecessary here.

[0031] The fire protection device 10 can be designed in different ways. The type of material chosen for the fire protection device 10 can be a factor in the design of the fire protection unit 6, for example. For example, a structure made of flexibly connected metal elements can have a certain inherent rigidity or stability and can be rolled up or folded. On the other hand, textile fabrics, such as glass fabrics, have lower rigidity and can be rolled up, for example. In combination with a load-bearing or supporting structure (e.g., made of metal), textiles can also be made into foldable shapes.

[0032] The control console 8 of the fire protection unit 6 can be mounted on the frame structure 2 or on a building wall to which the frame structure 2 is fixed. In one embodiment, the control console 8 includes a reel having a roller, coil, or cross-shaped structure, which is rotatable about a central axis. The central axis is substantially vertical. Figure 1 Extending along the z-axis. In this embodiment, the fire-resistant device 10 may primarily consist of a flexible textile fabric that is wound onto and unwound from a spool. In the unwound state, the fire-resistant device 10 extends parallel to the xz-plane within the wall shell region 2c, as shown in the image. Figure 1 and Figure 2 As shown.

[0033] Before further explaining the fire-resistant unit 6 and its working principle, details of the sliding door 4 are given below. The sliding door 4 has two generally parallel door panels 26 (located on the inner and outer sides of the sliding door 4, respectively). The door panels 26 are spaced apart (along the y-direction) such that an internal space exists between them, for example, to house system components and insulating materials for sound insulation and fire protection. The door panels 26 can be connected to each other in the region of their end faces 30 pointing towards the passage area 2b. Each door panel 26 extends parallel to the xz plane.

[0034] exist Figure 2 Exemplary system components of a building sliding door system 1 are shown: an electrical interface device 16, a controller 12 (DC), and a first drive unit 14 (M). In one embodiment, the building sliding door system 1 is connected to a building control system 20 (BM); Figure 2 In the illustrated embodiment, the connection is achieved via an electrical connection 28. Through this electrical connection 28, the building sliding door system 1 can, for example, be powered. In one embodiment, the operation of the building sliding door system 1 can be guaranteed using the supplied energy without requiring external control signals or commands to be sent to it. System components, such as inspection keys, access codes, or other types of access authorization, are integrated (locally) into the building sliding door system 1 in this embodiment, enabling the building sliding door system 1 to operate autonomously in addition to electrical power.

[0035] In another embodiment, external control signals or commands may be provided to the building sliding door system 1, for example, in conjunction with access authorization checks. 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 connected. The building management system 20 may include a computer-aided building management system in which data about authorized users and objects is stored.

[0036] Those skilled in the art will recognize that the building control system 20 can be arranged within a building, wherein the building control system 20 is designed as a local, 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 among subsystems or components arranged both locally within the building and remotely. For this purpose, the subsystems arranged within the building can be connected to an IT infrastructure used for so-called cloud computing (commonly referred to as the “cloud”). This includes, for example, storing data in a remote data center and running programs that are remotely installed rather than locally. Depending on the configuration, specific functionalities can be provided, for example, in the control device 12 or via the “cloud.” For this purpose, a software application or part of a program can be executed in the “cloud.” Then, when needed, the control device 12 accesses the infrastructure via the interface device 16 to execute the software application.

[0037] In the execution system, the electrical connection 28 may include an electrical bus system. In one embodiment, the electrical connection (including its power delivery) of the building sliding door system 1 is made via interface device 16. Those skilled in the art will recognize that multiple building sliding door systems 1 may exist in a building, and each of these building sliding door systems 1 may be coupled to the electrical connection 28 to communicate with the building control system 20, for example in conjunction with the determination and verification of access authorization, which is centrally performed by the building control system 20.

[0038] In the illustrated embodiment, the sliding door 4 includes a sensor unit 18 connected to the control device 12 via an electrical connection 32. The sensor unit 18 is arranged on the end face 30 of the sliding door 4, wherein the arrangement of the sensor unit is selected such that electromagnetic radiation (light or radio waves) emitted by, for example, the sensor unit 18 can propagate unimpeded toward the passage region 2b during operation. The sensor unit 18 can be inserted, for example, into a recess on the end face 30 and is protected by a radiation-permeable cover from damage and dirt. The control device 12 is also connected to the first drive unit 14 and the interface device 16 via an electrical connection 34. The electrical connection 32 between the sensor unit 18 and the control device 12 (… Figure 1) and electrical connection part 34 ( Figure 1 The electrical connections 32 and 34 extend within the sliding door 4, for example, between the door panels 26. These electrical connections are used for signal and / or energy transmission and may each comprise a separate electrical line or electrical bus system.

[0039] Below, for reference Figures 3A to 3C This section introduces the working principle of building sliding door system 1. Figures 3A to 3C Schematic diagrams of horizontal cross-sections of embodiments of a building sliding door system 1 having sliding doors 4 and fire-resistant units 6 are shown. In each of these figures, components included by the sliding door 4 are depicted: sensor unit 18(S), control device 12(DC), and first drive unit 14(M); for illustrative purposes, interface device 16 and its connection to the building control system 20 are not shown. The first drive unit 14 and control device 12 are arranged within the sliding door 4, particularly between the door leaves 26. Figures 3A to 3C Also shown is a fire-resistant unit 6 located in the wall shell area 2c, which has a control console 8 and a fire-resistant device 10.

[0040] 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 panels are coupled to an actuator that moves the door panels toward or away from each other. Based on the building sliding door system 1 according to the technology described herein, this means 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 3A to 3C The two door panels move toward each other to such an extent that they have a door panel distance d2, which is set such that the sliding door 4 has such a small thickness in its fully or partially open position (3B and 3C) that the sliding door fits into the receiving structure of the wall shell region 2c. The door panel distance d1 is greater than the door panel distance d2. When the sliding door 4 is pushed out of the wall shell region 2c, the two door panels 26 move away from each other (separate), so that the sliding door 4 is in the closed state ( Figure 3A The wall has a fixed thickness. The thickness is determined 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). This results in a substantially smooth finish on the two wall sides in the door area.

[0041] In one embodiment, the building sliding door system 1 has a guide device on the door lintel that carries the sliding door 4 and guides it between a closed and open position along its path. For this purpose, the sliding door 4 has a complementary device on its upper edge. When the first drive unit 14 moves the sliding door 4, the guide device and the complementary device cooperate and, for example, act on the complementary device. The guide device and the complementary device form, for example, a roller mechanism (e.g., a roller-supported slide system (roller slide)). The first drive unit 14 may, for example, include a motor or pneumatic push-pull actuator that acts, for example, on the sliding door 4. Those skilled in the art will appreciate that this design is not limited to a roller mechanism, and the guide device and the complementary device can be designed in different ways, for example, as a telescopic extension.

[0042] 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 opening and closing mechanism. The opening and closing mechanism is designed such that when the sliding door 4 is to be opened, the two door panels 26 move toward each other, and when the sliding door 4 is to be closed, the two door panels 26 move away from each other. Those skilled in the art will appreciate that alternative opening and closing mechanisms, such as cylinders operated by a pressure medium, may also be provided.

[0043] As mentioned elsewhere in this specification, the fire protection device 10 is in the retracted position relative to the control console 8 within the wall shell area 2c, along the horizontal axis. Figure 3C ) and retraction position ( Figure 3A The sliding door 4 moves between the two positions. In the retracted position, the sliding door 4 is in the open position, and in the extended position, the sliding door 4 is in the closed position. Figure 3B Exemplary positions of the fire-resistant device 10 with portions extended or retracted are shown. It can also be seen in these figures that the effective fire-resistant surface formed by the fire-resistant device 10 depends on the degree to which the fire-resistant device 10 is extended or retracted. Those skilled in the art will understand that, in particular, the fire-resistant surface between the fire-resistant device 10 and the wall panels 23, 25... Figure 3A and Figure 3B The visible distances are not drawn to scale.

[0044] According to one embodiment, the fire-resistant unit 6 is designed as a passive fire-resistant unit 6. In one embodiment, the fire-resistant device 10 is coupled to a sliding door 4, wherein the fire-resistant unit 6 is designed such that the sliding door 4 moves the fire-resistant device 10 horizontally from a fully or partially retracted position to a fully or partially extended position. The sliding door 4 may be coupled to the distal end of the fire-resistant device 10 and pull the fire-resistant device to extend the fire-resistant device 10. In one embodiment, the fire-resistant unit 6 may be designed such that the sliding door 4 moves the fire-resistant device 10 horizontally from a fully or partially extended position to a fully or partially retracted position. In one embodiment, the fire-resistant device 10 can therefore extend and retract through the sliding door 4. In this embodiment, this also means that the fire-resistant device 10 and the sliding door 4 move together.

[0045] In one embodiment, the fire-resistant unit 6 may be designed such that the fire-resistant device 10 extends against a restoring force. For example, the restoring force supports the retraction of the fire-resistant device 10 through the sliding door 4. In another embodiment, the fire-resistant device 10 may retract autonomously by a restoring force without needing to be moved through the sliding door. In these embodiments, the fire-resistant device 10 and the sliding door 4 may also move together.

[0046] To apply a restoring force, one or more springs may be present in the fireproof unit 6, which are tensioned when the fireproof device 10 is extended. For example, the control console 8 may have a helical spring mechanism (roller spring mechanism) in which the helical spring moves back and forth between two housings (e.g., as a reel for an output roller and a storage roller). When the fireproof device 10 is extended (i.e., when the helical spring mechanism is pulled up), the spring is wound up in the output roller. At the end, the spring retracts into the storage roller to return to its original shape, and here drives the reel.

[0047] According to another embodiment, the fire protection unit 6 can be designed as an active fire protection unit 6. For this purpose, the fire protection unit 6 can have an electromechanical second drive unit 7 (electric motor). Figure 2 The electromechanical second drive unit is connected to the control device 12 and / or the interface device 16. The operation of the second drive unit 7 can be designed to cause the fire-resistant device 10 to retract and extend. In this case, it is not necessary for the sliding door 4 to extend or retract the fire-resistant device 10. In another embodiment, the operation of the second drive unit can be designed to cause the fire-resistant device 10 to extend only in the event of a fire alarm.

[0048] According to another embodiment, a retaining device can be provided in conjunction with the passive design of the fire-resistant unit 6, which is triggered only in the event of a fire alarm. The building sliding door system 1 can be designed such that the fire-resistant device 10 remains in the retracted position and the sliding door 4 moves independently therefrom. If a fire alarm is triggered in the building, the fire-resistant device 10 extends. This can be achieved by controlling the movement of the sliding door 4 from the closed position to the open position to engage with the fire-resistant device 10, and the sliding door 4 is closed when it subsequently moves back to the closed position. The advantage of this is that only one actuator is required, and the extension of the fire-resistant device 10 can still be controlled. Therefore, the fire-resistant unit 6, and in particular the fire-resistant device 10, suffers less wear and tear. In this design, the fire-resistant device 10 can also extend only, for example, at night or when the building is empty; in other cases, such as during business hours, office hours, or periods of frequent use, the fire-resistant device can remain in a "deactivated position".

[0049] Figure 4 A schematic diagram of the building sliding door system 1 is shown in side view. The sliding door 4 is movable along an upper guide rail 40 and a lower guide rail 48. In one embodiment, the sliding door 4 has a first roller mechanism 44, by which the sliding door 4 is suspended on the upper guide rail 40. The lower guide rail 48 supports the sliding door 4 in the x-axis direction and prevents (or reduces) possible swaying in the y-axis direction. In one embodiment, the fire-resistant device 10 can also be movable along these guide rails 40, 48; for example, it can also be suspended within the upper guide rail 40.

[0050] The sliding door 4 is connected to the fireproof device 10 via the example connecting element 46.

[0053] The second roller mechanism 50 is shown, for example, as a pair of rollers, wherein the rollers in the pair are arranged on opposite sides of the fire protection device 10. The second roller mechanism 50 may have more than one pair of rollers along the x-axis. Those skilled in the art will appreciate that the illustrated guide device with the second roller mechanism 50 is exemplary, and the guide device can also be designed in different ways; for example, the rollers may be arranged only on one side of the fire protection device 10, or a sliding mechanism may be used instead of the second roller mechanism 50.

[0054] In another embodiment, the fire-resistant device 10 can be fixed to the sliding door 4 and / or its guide rail or guide slide. In this case, the fire-resistant device 10 does not need to be provided with a separate guide rail (or guide slide). Here, the reinforcement at the upper end of the fire-resistant device 10 can tighten the fire-resistant device 10. Those skilled in the art also know that, as an alternative to passing through the passage 56, the fire-resistant device 10 can be arranged laterally on the guide rail 40, as in... Figure 6 As shown, the fire-resistant device 10 can be moved along the longitudinal outer side 54 of the guide rail 40. If a single fire-resistant device 10 is insufficient to meet certain fire protection requirements, two fire-resistant devices 10 can be provided, each of which can be moved by means of this lateral arrangement.

[0055] In one embodiment, the lower guide rail 48 ( Figure 4 This can be used to guide the fire protection device 10 along the x-axis direction from below. In another embodiment, a separate guide rail can be provided for the fire protection device 10, or the guide at the bottom of the fire protection device 10 can be omitted.
