Description

Technical Field

[0001] This invention relates to an elevator system. The elevator system for transporting passengers or goods has an elevator car capable of moving between floors within an elevator shaft. At least one shaft door for closing the elevator shaft is provided on at least one floor. The shaft door includes a door leaf with an integrated control and / or display panel. The invention also relates to a control and / or display panel for such an elevator system. Background Technology

[0002] Elevator equipment used for transporting people and goods has been known and commonly used for a long time. Call detection units for receiving floor calls are typically located on the floors. When someone makes a floor call from the departure floor, the elevator car travels to that floor. Floor indicators integrated into the door frame of the shaft door inform personnel which floor the approaching elevator car is currently located on.

[0003] A door leaf with an integrated control and display panel for a shaft door of an elevator system is known from WO2014 / 067895A1. Summary of the Invention

[0004] One object of the present invention is to provide an elevator device having door panels with integrated control and / or display panels, which meets high safety requirements even in the event of a fire.

[0005] According to the present invention, this and other objectives are achieved by an elevator device. The elevator device for transporting people or goods may include an elevator car capable of moving between floors within an elevator shaft. The elevator device also includes at least one shaft door comprising door panels through which access from a floor to the elevator car is made. The elevator device may then have an elevator control unit for operating the elevator device, specifically controlling a drive unit for moving the elevator car. An operating and / or display panel is integrated into the door panel. Control commands can be input to the elevator control unit using the operating panel. The display panel is used to display information. For example, the operating panel may include a display element, such as a light-emitting display, to confirm the input commands. On the floor side, for example, an operating unit designed as an operating panel may be provided, particularly in the form of a call detection unit for inputting floor calls. The operating panel can also be used to detect target calls. The operating and / or display panel may also be designed as a floor indicator or include a floor indicator. Floor information signals to the person calling the elevator car which floor the elevator car is currently on. Alternatively, the control and / or display panel may also indicate which target floor was selected after a target call was made, in the presence of a target call control mechanism.

[0006] By equipping the door panels with pop-out devices, the control and / or display panels can be at least partially removed from the door panels in the event of a fire, ensuring that the elevator equipment with such doors still meets high safety requirements during a fire. "Partially" refers to the control and / or display panels, which should not be completely removed from the door panels but rather partially removed by means of the pop-out devices in the event of a fire. Relatively flammable and combustible components of the control and / or display panels can be safely and reliably separated from the door panels. Without these components, the door panels can withstand higher temperatures in the event of a fire. This significantly improves the fire safety of the elevator equipment. The door panels are preferably equipped with pop-out devices that are automatically activated by heat. In this case, the pop-out devices are activated in the event of a thermal overload, i.e., when a predetermined temperature corresponding to the occurrence of a fire is exceeded. Upon activation, the ejector device will push the component to be removed from the control and / or display panel, or if necessary, the entire control and / or display panel, outward until it falls; or, upon activation of the ejector device, the component to be removed from the control and / or display panel will move outward until it falls.

[0007] Preferably, each floor of the elevator system is equipped with a shaft door, which has a door leaf with an integrated control and / or display panel having the aforementioned pop-out device. However, it is also conceivable that not every floor has such a fire door.

[0008] In a first embodiment, the ejection device includes a heat-extending actuator having a shape memory metal or bimetallic structure. However, it is also conceivable that the heat-extending actuator comprises an extension material element. Alternatively, the ejection device may have an actuator that can be activated by heat, having a pre-tensioned spring to form a mechanical accumulator. The spring-containing actuator may have an actuator housing in which the spring is arranged. The actuator housing holds the spring in a pre-tensioned, ready-to-use position. The actuator housing may be made, for example, of a composite material that melts in a fire and thus releases the spring to generate a spring force, thereby achieving the desired movement for removing the corresponding component of the operating and / or display panel. The actuator housing may also be made of a heat-resistant material such as metal. In this case, the actuator housing may securely hold the spring in the ready-to-use position by means of a brazed connection. When the brazed connection melts in a fire, the pre-tensioned spring is released and the spring force causes the desired movement, causing at least a portion of the operating and / or display panel to be removed from the door.

[0009] In a preferred embodiment, the ejector device includes an inflatable material. Thanks to the ejector device, which can be operated with the inflatable material, at least a portion of the operating and / or display panel can be removed from the door in a simple and reliable manner. The inflatable material is a material known in fireproofing that expands in volume under heat. The inflatable material forms an actuator that, based on the increase in volume of the inflatable material, induces movement in the event of a fire, causing the operating and / or display panel to move or at least partially move outward. The advantage of an ejector device incorporating inflatable material is a high level of safety and reliability. In practice, this ejector device reliably prevents malfunctions.

[0010] Intumescent materials can be formed from organic synthetic materials and other additives. In the event of a fire, the intumescent material foams to form a non-combustible or flame-retardant material, thus providing a flame-retardant effect. Intumescent materials can be made, for example, from polyurethane incorporating expanded graphite or "Vermiculite®," whereby the expanded graphite doubles in volume upon ignition. Alternatively, intumescent materials can be manufactured based on epoxy resins with added additives. Besides polyurethane, silicone foam composites and / or polyimide foam composites can also be used to manufacture intumescent materials.

[0011] Thanks to this expandable material, the door panel can achieve excellent thermal insulation.

[0012] The door panel has an outer wall, preferably made of metal sheet, facing the floor to cover the shaft passage. The door panel may also have a rear wall, also made of metal sheet. A supporting structure made of the same metal can be provided between the outer wall and the rear wall, which are typically arranged parallel to each other and spaced apart by a certain distance.

[0013] The control and / or display panel may include a circuit board and a carrier frame for supporting the circuit board, wherein, in the event of a fire, the circuit board can be removed from the door leaf by means of a pop-out device, and the carrier frame is preferably fixedly connected to the door leaf. In other words, in the event of a fire, the circuit board can be removed from the door leaf by means of a pop-out device, while the carrier frame remains on the door leaf. Therefore, the control and / or display panel is not completely separated, but only a part of it, namely the circuit board, is separated. The carrier frame is preferably made of the same metal as the door leaf. The circuit board may contain electronic components for operating the control and / or display panel. In addition to the circuit board, components to be removed in the event of a fire may also include, for example, a touch screen surface. The circuit board and the touch screen surface contain flammable or combustible parts. Removing such fire safety sensitive components is advantageous. Of course, other components such as flexible buttons may also be arranged on the circuit board instead of on the touch screen surface.

[0014] The expanding material can be arranged on the circuit board, for example, in the form of strips. This expanding material can be a component of the aforementioned ejection device. This expanding material can also form spacers to maintain separation, at least in the first stage, from the built-in metal door components that protect the sensitive circuit board from the heat of a fire.

[0015] Advantageously, a ejector plate that can move toward the circuit board is arranged in the door leaf. The ejector plate is part of the ejection device. In the event of a fire, the ejector plate moves toward the circuit board, for example, using an actuator as described above; the ejector plate contacts the circuit board and knocks the circuit board away upon further movement.

[0016] Preferably, the ejector plate is designed such that, after a portion of the control and / or display panel is removed from the door leaf, the ejector plate closes the gap in the door leaf created by the removal process. This significantly improves fire safety.

[0017] When the control and / or display panel has a circuit board and a carrier frame, the ejector plate is preferably designed and constructed in the door leaf in such a way that after the circuit board is removed, the ejector plate closes the carrier frame or the internal space of the carrier frame.

[0018] Particularly preferred is that a guiding mechanism for the guided movement of the ejector plate is provided in the door leaf, or particularly preferred is that the operating and / or display panel has a guiding mechanism for the guided movement of the ejector plate. This guiding mechanism can be, for example, a guide rod or other guiding element, arranged in the door leaf and extending horizontally between the outer wall and the rear wall corresponding to the operating and / or display panel, the rear wall being opposite to the outer wall and preparing for the case of the elevator car shaft door. However, the guiding mechanism can also be a guiding element belonging to the operating and / or display panel. The ejector plate advantageously has a mechanism corresponding to the guiding mechanism, for example in the form of a recess or notch, which remains effectively connected to the aforementioned guiding mechanism.

[0019] To facilitate the guidance of the launch plate, the guiding element formed by bending on the carrier frame can take the form of a guide tongue, for example, serving as a guiding mechanism. Preferably, the guiding element, formed on and integrally connected to the carrier frame, can be arranged on both sides of the carrier frame. The guide tongue is an arm segment formed by bending, preferably joined at right angles to the outside of the frame. The guide tongue and the carrier frame form a U-shape in cross-section. Particularly preferably, two guide tongues or other guiding elements are formed or fixed to the carrier frame on each side. The launch plate may have slits in which the guide tongues are received.

[0020] To ensure the reliable operation of the ejection device, it is advantageous to mount the expanding material, preferably in the form of a plate, on the ejection plate. At least one or more such plates may be mounted on the ejection plate. The expansion effect can be adjusted by the thickness of the plates(s). Alternatively, the expanding material may be mounted on the rear wall. In the event of a fire, the expanding material, whose volume increases, will propel the ejection plate against the control and / or display panel, ultimately dislodging it.

[0021] When expansion material is provided on both the launch plate and the rear wall, a two-stage ejection motion or ejection process will occur.

[0022] The door leaf may have a rear wall, wherein the rear wall may be closed in the area of ​​the operating and / or display panel by a cover removably fixed to the rear wall. The rear wall or cover may form a fixed stop for the ejection device, on which the ejection plate or its expansion material may be supported in the event of a fire, thereby achieving ejection.

[0023] Another aspect of the invention relates to a control and / or display panel for elevator equipment, and more particularly to a control and / or display panel for the aforementioned elevator equipment. The advantage of a control and / or display panel comprising a circuit board and a carrier frame for supporting the circuit board is that such a control and / or display panel has an expansion material for fire safety. For example, in the event of a fire, the expansion material can be used to separate the circuit board from the carrier frame. Instead of an expansion material, or if necessary, an extension thereof, the control and / or display panel may have an actuator that extends when heated or an actuator with a pre-tensioned spring to form a pop-out device, which can be used to separate the circuit board from the carrier frame in the event of a fire.

[0024] Finally, another aspect of the invention relates to a fire-resistant flat-panel elevator component with an integrated control and / or display panel. Since the aforementioned control and / or display panel and ejection device can also be used in other flat-panel elevator components as an alternative to the door panels of the elevator shaft doors, and are advantageous for these flat-panel elevator components. In the present context, a flat-panel elevator component is understood to refer to a plate-like or other flat-panel member used to enclose the space or other boundaries of the elevator shaft and elevator car; thus, it applies not only to door panels but also to car walls, floors, ceilings, and windows, etc. A flat-panel elevator component can also be a component of the door frame of the shaft door. In conventional elevators, the call detection unit is typically arranged on the front wall of the shaft next to the shaft door. The control and / or display panel or its components (e.g., circuit boards) arranged on the front wall of the shaft can also be removed from the front wall of the shaft in the aforementioned manner by means of an ejection device in the event of a fire.

[0025] Preferably, the flat-panel elevator component is designed such that, after the entire control and / or display panel or its corresponding components have been removed from the flat-panel elevator component, the gap created by the removal is closed by means of a ejector plate. As an alternative to the control and / or display panel, the fire-resistant flat-panel elevator component may also have other potential fire hazards, such as control devices, which can be removed from the flat-panel elevator component in the event of a fire by means of an ejector device.

[0036] Figure 1An elevator system, designated 1, for use in a multi-story building is shown. The building has an elevator shaft 3, or multiple elevator shafts as needed. The elevator system 1 illustrated herein comprises an elevator car 2 that can move vertically up and down within the elevator shaft 3 for transporting people or goods to various floors. The elevator car 2 has a car door 16. A shaft door 8 is provided for each floor 4. The elevator system 1 has a counterweight 5 connected to the elevator car 2 via a hoisting device (e.g., belt, cable). A drive unit 6, controlled by an elevator control unit 6, is provided for moving the elevator car 2 and the counterweight 5. The drive unit 6 (e.g., a traction sheave drive) drives the hoisting device, thereby causing the car 2 and the counterweight 5 to move in opposite directions.

[0037] Shaft door 8 is designed as the floor door of elevator equipment 3, enclosing elevator shaft 3 and forming a passageway from floor 4 to elevator equipment 3. If a person on floor 4 wants to use the elevator, they operate the control panel marked 10, for example, by pressing a button. This button can be an expandable button. The button can also be pre-defined via a touchscreen interface.

[0038] In the current configuration, the control panel 10 is designed as a call detection unit for inputting floor calls. After a floor call is issued, the elevator car 2 moves to the floor where the call was made. To notify passengers waiting in the elevator car 2, the control panel 10 may include a floor indicator 10; therefore, component 10 may also be referred to below as the "control and display panel". The floor indicator displays the elevator car's location information, such as which floor the elevator car is currently on. Instead of or attached to this commonly used digital indicator, the control and display panel 10 may include a direction indicator. The direction indicator indicates which direction the elevator car is currently moving in. The control and display panel 10 may also indicate: the elevator car is about to arrive, whether the elevator car is currently waiting behind the shaft door, whether the elevator car is empty or full, where the elevator car is going next, etc. The aforementioned indicators may also be provided by a display panel 10, independent of the control panel 10 and also integrated into the door panel 9.

[0039] The shaft door 8 is equipped with a pop-out device (not shown here), which is described in detail below, allowing the operating and / or display panel 10 to be completely or partially removed from the door leaf 9 in the event of a fire. Figure 1 The fire situation is illustrated schematically. The pop-out device of the shaft door 8' on floor 4' is activated by the temperature generated during the fire, and the operating and / or display panel, indicated by 10', separates from the door leaf of the shaft door 8' and falls to the floor.

[0040] Figure 2The shaft door 8 is shown from the front of floor 4. The shaft door 8 has two door panels that can move in opposite directions, allowing it to move between an open position and a closed position. In this embodiment... Figure 2 The rightmost door leaf, designated by 9, is equipped with a control and / or display panel 10. The left door leaf, designated 9', can alternatively be equipped with a control and / or display panel 10. It is even conceivable that both door leaves 9 and 9' be equipped with control and / or display panels 10. Door leaf 9 is equipped with a previously mentioned (not shown) ejector device, by which the control and / or display panel 10 can be completely or partially removed from door leaf 9 in the event of a fire.

[0041] Figure 3 A door leaf 9, in which an operating and / or display panel 10 is integrated, is shown. The door leaf 9 has an outer wall 20 and a rear wall 21, the rear wall 21 extending parallel to and at a distance from the rear wall. Furthermore, a support structure (not shown) may be provided between the outer wall 20 and the rear wall 21, connecting the two walls and ensuring sufficient rigidity of the door leaf. The operating and / or display panel 10 is fixed to the outer wall 20. Fixing can be accomplished, for example, by adhesive bonding. The ejection device 11 includes an actuator with a pre-tensioned spring 12. The spring 12 is held in an actuator housing 13 made of synthetic material, which holds the spring 12 in a pre-tensioned standby position. This position corresponds to the normal state of the elevator equipment. In the event of a fire, the actuator housing 12 melts and releases the spring 12. The spring 12 then pushes the operating and / or display panel 10 in the direction indicated by f until the operating and / or display panel 10 falls off. Figure 4 The image shows door 9 after the pop-out device 11 is activated in the event of a fire. In this manner, the control and / or display panel 10 can be removed from door 9.

[0042] By appropriately selecting an adhesive or by applying the adhesive in dots, the aforementioned adhesive bond is advantageously weakened to such an extent that the spring force can separate the operating and / or display panel 10 from the outer wall 20. Instead of adhesive bonding, detachable connections are also possible. Mechanical fastening using screws or the like is also possible. The mechanical fastening of the operating and / or display panel 10 to the outer wall 20 may have a rated breakage point or element that breaks or otherwise yields when subjected to spring force, thereby allowing the operating and / or display panel 10 to be removed in the event of a fire.

[0043] Instead of based on Figure 3The actuator has a pre-tensioned spring 12. The ejection device 11 may also include a body made of an expanding material (not shown here) that, in the event of a fire, causes the control and / or display panel 10 to be ejected outward due to the expansion of the expanding material under heat.

[0044] exist Figure 5 A variation of the ejection device 11 based on inflatable material is shown. A body 19 made of inflatable material is attached to the inside of wall 21. In door 9, an ejector plate 16 is arranged between the inflatable material 19 and the control and / or display panel 10. The ejector plate 16 is movably supported on guide rod 22. When the inflatable material 19 foams in the event of a fire, the ejector plate 16 moves toward the control and / or display panel 10 in the direction indicated by arrow f. The ejector plate 16 then ejects the control and / or display panel 10 from its fixed portion in outer wall 20. The ejector plate 16 impacts the outer wall 20 on the inside and closes any gaps left in the outer wall 20 due to the falling control and / or display panel 10. Thanks to the inflatable material 19, an advantageous ejection device 11 that is automatically activated by heat is achieved to remove the control and / or display panel 10 containing flammable or combustible components, which has a positive impact on the fire safety of elevator equipment 1.

[0045] To optimize the ejection process, an expansion material 18 is attached to the inner side of the control and / or display panel 10, which additionally facilitates the ejection of the control and / or display panel 10. However, the expansion material 18 may be omitted, particularly when the inner side of the control and / or display panel 10 has a bulge or protrusion pre-defined by electronic components or, if necessary, by additional spacers, for reliable separation.

[0046] Figure 5 The structure shown with the ejector plate 16 would also be advantageous if other actuators were used. Thus, the expansion material 19 could be replaced by an actuator with a pre-tensioned spring that can be activated by heat, or, if necessary, by an actuator with a shape memory metal or bimetal that can stretch when heated.

[0047] Figures 6 to 9 Another embodiment of the door leaf 9 relating to the shaft door 8, wherein the door leaf 9 has an integrated control and / or display panel 10, and the door leaf 9 has a pop-out device 11 based on an expansion material for removing the control and / or display panel 10 at least partially from the door leaf 9. The control and / or display panel 10 includes a circuit board 14 having electronic components for operating the control and / or display panel and a carrier frame 15 for supporting the circuit board 14. A touch screen surface 25 may be arranged on the circuit board 14. However, other control and display elements may also be provided if necessary.

[0048] The circuit board 14, having a touchscreen surface 25, can be adhered to the carrier frame 15. From Figure 8 As can be seen from the example, the expansion material 18 is arranged on the circuit board 14. The expansion material 18 can form spacers, thereby separating the circuit board 14 from the built-in metal door panel component 17 that heats up in the event of a fire. As for the rest... Figure 6 , Figure 7 and Figure 8 As shown, the expansion material 18 arranged on the circuit board 14 can also be omitted.

[0049] A rectangular recess 27 corresponding to the outer wall is indicated by a dashed line, into which the control and / or display panel 10 is inserted. After being inserted from the inside, the control and / or display panel 10 is fixed to the outer wall using adhesive. A corresponding frame-shaped adhesive area on the carrier frame 15 is indicated as 26. The recess 27 in the outer wall 20 can... Figure 2 I saw it again in the middle.

[0050] Furthermore, a launch plate 16 movable toward the circuit board 14 is arranged inside the door leaf 9. A guide element in the form of a guide tongue 23, formed by bending, is formed on the carrier frame 15 to guide the launch plate 16. The launch plate 16 has four slits 24 in which the guide tongue 23 is accommodated. Thus, the launch plate 16 can be easily guided horizontally along the guide tongue 23.

[0051] An expansion material 19 in the form of a relatively thick plate is attached to the ejection plate 16. The rear wall 21 is closed in the area of ​​the control and / or display panel 10 by a cover 17 detachably fixed to the rear wall. The cover 17 forms a fixed stop on which the expansion material 19 can be supported in the event of a fire.

[0052] Like the outer wall 20, rear wall 21, and support structure, the ejector plate 16 is made of metal, and is therefore relatively fireproof. The ejector plate 16 is designed and integrated into the door leaf 9 in such a way that after the circuit board 14 is removed, the ejector plate closes the carrier frame 15 or the internal space of the carrier frame.

[0053] In the event of a fire, for example, the following situation may occur: when a fire occurs inside a building, the smoke and hot gases generated by the fire can reach the shaft door through the elevator shaft. When a certain temperature is exceeded, the expansion material 19 is activated. At this time, the activated expansion material 19 increases its volume, causing the ejector plate 16 to be pushed towards the circuit board 14. The expansion material 18 arranged on the circuit board 14 can also increase its volume due to heat, thereby causing the circuit board 14 to move further outward. Therefore, the circuit board 14 can be pushed outward in a highly efficient manner until it falls. However, in the event of a fire, it is also possible to consider the following situation: the expansion material 18 is activated first, and then the expansion material 19 is activated. The ejection device 11 shown here, which has two expansion materials 18 and 19, thus produces a two-stage ejection process. The ejector plate 16 moves further to the outer wall 20 and closes the carrier frame 15. The gap in the recess 27 in the door leaf 9 created by the removal of the circuit board 14 is then closed again.
