Description

Technical Field

[0001] The technology described herein generally relates to an elevator and a method for displaying information at or within the elevator. More specifically, the technology relates to an elevator door for displaying information, an elevator car including the elevator door, an elevator including the elevator door and / or the car, and a method for displaying information at or within the elevator (e.g., in the car and / or on a floor of a building in which the elevator is arranged, at the elevator). Background Technology

[0002] Elevators are used to transport passengers throughout the shaft of a building using elevator cars. Typically, multiple passengers and / or one or more goods can be accommodated in the car and then transported from a starting floor to a landing floor. During such a journey of the car, other passengers may enter or leave the car during intermediate stops at other floors, where these passengers may have called the car from one of those floors. Passengers who called the car and are waiting in front of one of the landing doors, as well as passengers inside the car, may be interested in information about the car's current journey. For example, a passenger waiting for the car may be interested in the car's current location (i.e., on which floor) and / or the location where the passenger is waiting for the car (i.e., on which floor). In contrast, passengers inside the car may be interested in where the car is currently (i.e., on which floor) and / or from which it was called (i.e., from which floor), in other words, which call (e.g., from which floor) is still pending processing.

[0003] It is known that keypads for calling the car to a building floor are positioned next to the landing door at the hoistway opening. Furthermore, it is known that keypads for selecting the destination (i.e., the floor) are positioned inside the car near the car door. In many cases, these keypads include buttons with a light source configured to display information about the car's current location, which calls are waiting, and / or the current landing floor. Additionally, scales containing the building's floor numbers may be printed on or next to these buttons, or a display for showing the numbers may be positioned next to or above the keypad.

[0004] However, most passengers automatically look towards the elevator doors. Specifically, passengers waiting for the elevator on a floor typically look towards one or more landing doors on that floor, while passengers moving inside the elevator typically look towards one or more car doors. Therefore, placing the keypad and / or numbers next to the corresponding doors and thus guiding passengers' gaze away from those doors is not very intuitive, and passengers may miss some information when not looking towards the corresponding door. Furthermore, when two or more passengers are waiting for the elevator or moving inside, at least some of them may block the view of other passengers towards the keypad and / or displays next to the doors. Summary of the Invention

[0005] Therefore, a possibility may be needed that allows information about the current travel of an elevator car to be presented in an intuitive, cost-effective, easy, and / or simple manner, and / or to ensure that one or more passengers of the elevator do not miss the information. Furthermore, a car and / or elevator that provides the possibility of presenting the information accordingly may be needed. Additionally, a method for displaying information at or within the elevator may be needed that allows the information to be presented in an intuitive, cost-effective, easy, and / or simple manner, and / or to ensure that one or more passengers of the elevator do not miss the information.

[0006] This need can be met by the subject matter of the independent claims. Advantageous embodiments are defined in the dependent claims, as well as in the following description and related drawings.

[0007] According to a first aspect of the technology described herein, an elevator door is described for opening or closing a passageway for entering an elevator car. The elevator door includes a first set of two or more first light sources arranged vertically above and below each other when the elevator door is oriented as intended for its purpose, wherein the first light sources are configured to indicate at least one piece of information regarding the current travel of the car.

[0008] According to a second aspect of the technology described herein, a car for an elevator is described. The car includes at least the aforementioned first door, wherein the first door is arranged in the car such that it is movable in a horizontal direction, and such that a first end surface is a front surface in the closing direction of the first door.

[0009] According to a third aspect of the technology described herein, an elevator for a building is described. The elevator includes the aforementioned car and a control unit communicatively coupled to light sources at one or both elevator doors of the car, and the control unit is configured to activate or deactivate one or more of the light sources to display one or more pieces of information regarding the current travel of the car accordingly.

[0010] According to a fourth aspect of the technology described herein, an elevator for a building is described. The elevator includes: a shaft extending across two or more floors of the building in which the elevator is disposed, wherein the shaft is configured such that an elevator car can move from one floor to another; shaft openings for entering or exiting the car at each of the floors where entry or exit is possible; at least one first door, as described above and below, at each shaft opening, wherein the first door is mechanically and horizontally movable to the building at the respective floor; and a control unit communicatively coupled to a first light source at the first door, and the control unit is configured to activate or deactivate one or more of the first light sources to display one or more pieces of information regarding the current travel of the car accordingly.

[0011] According to a fifth aspect of the technology described herein, a method for displaying information at or within an elevator is described. The method includes: determining one or more pieces of information regarding the current travel of the elevator car; and, based on the determined information, activating or deactivating two or more light sources on the elevator doors, wherein the elevator doors are configured according to a first door as described above and below.

[0012] It should be noted that the possible features and advantages of embodiments of the technology described herein are described in part with respect to one aspect of the foregoing and in part with respect to another aspect of the foregoing. Those skilled in the art will recognize that features can be suitably transferred from one aspect to another and / or from one embodiment to another, and that features can be modified, adapted, combined, and / or replaced, etc., to lead to further embodiments of the technology described herein.

[0013] Elevators can be installed in buildings with shafts, in which the car moves from one floor to another. Most passengers waiting in the car on one of the floors corresponding to the shaft opening, as well as most passengers already in the car, view the elevator doors, or, in the case of two doors, view the elevator doors themselves. Therefore, placing the first set of light sources at the elevator doors helps passengers perceive information in a very comfortable, intuitive, and pleasant way. This helps passengers not miss information. This can contribute to passenger safety and / or a good passenger experience.

[0014] The light source may each include, for example, one or more LEDs or OLEDs. The light source may be a light-emitting component of an LED strip, wherein the LED strip is arranged at the elevator door. The first set of LED strips and / or light sources may be a component attached to a light panel of the elevator door. The doorway may be a doorway at one of the shaft openings. In this case, one or more elevator doors may be one or more landing doors of the elevator. Alternatively, the elevator doorway may be a doorway of the elevator car. In this case, one or more elevator doors may be one or more car doors of the elevator car.

[0015] The light sources can be distributed across the entire height of the elevator door, with at least one light source positioned near the bottom of the elevator door and at least one light source positioned near the top of the elevator door. In this case, when the elevator door is open, the light source near the bottom can additionally illuminate the threshold of the elevator shaft or the gap between the car and the building within the elevator shaft. Alternatively, the light sources can be arranged within a vertical extension of the elevator door that is much smaller than the height of the elevator door. For example, this extension may extend beyond approximately half or a quarter of the height of the elevator door. For example, this extension may be positioned at a height corresponding to the eye level of an average adult passenger.

[0016] The current journey of the car can begin when a call to the car is made from one of the floors of the building. The current journey of the car can end when the last passenger has left the car and there are no calls pending from another floor of the building. During the current journey of the car, the car can be called from one or more floors, the car can be moved to one or more floors based on pending calls, and / or the car can be moved to the floor called from inside the car.

[0017] Optionally, there are no buttons or switches, such as those for selecting floor levels, located at the elevator doors, and / or coupled to the light sources. Therefore, it is possible that the first set of light sources cannot be used as a control element for controlling the movement of the elevator car. Instead, it is possible that the first set of light sources can be used only to provide information associated with the respective light source and / or the color of the light emitted by that light source.

[0018] For ease of explanation, it is assumed throughout this specification that the elevator door is oriented as intended for its purpose. In this context, this may mean that, if the elevator door is one of the landing doors, it is oriented to be located at the corresponding shaft opening in one of the floors of the building, or if the elevator door is one of the car doors, it is oriented to be located in the car. When the elevator door is oriented as intended for its purpose, it has a bottom surface facing downwards and a top surface facing away from the bottom, wherein the bottom and top surfaces are perpendicular to the main surface and the first end face. The door has another end face opposite to the first end face. However, this other end face may not play any significant role in the invention, as it is generally not visible when the elevator door is located in the elevator shaft, as it is intended for its purpose.

[0019] When elevator doors are located in the car, the elevator door (e.g., the first door) is the first car door of the car. When elevator doors are located at one of the shaft openings in one of the floors, the elevator door (e.g., the first door) is the first landing door of the shaft. Optionally, the elevator includes at least one car door (i.e., the first car door) and at least one landing door (i.e., the first landing door), which is located, for example, on at least one floor of the building, for example, at least one first landing door on each floor. Each of the elevator doors can be a single door or a telescopic door with two or more door panels. The closing direction is parallel to the horizontal direction.

[0020] This information can be determined by a control unit, such as a floor control unit for controlling the corresponding landing door or a car control unit for controlling the car doors. In this case, the control unit can be coupled to several sensors capable of detecting where the car is positioned, where the car is currently being called from, and / or which floor has been selected as the landing floor. Alternatively, this information can be sent from an elevator control unit coupled to the sensors and configured to control the movement of the car through the hoistway. The elevator function controlled by at least one of the control units can be, for example, any function relating to the movement of the car, for example, in the vertical direction and / or the movement of one or more doors, for example, in the horizontal direction. The movement of the car can be controlled by the respective control unit via a motor for lifting the car. The movement of one or more doors can be the movement of one or more car doors or one or more landing doors.

[0021] According to one embodiment, an elevator door includes: a first main surface extending in both vertical and horizontal directions; a second main surface opposite to the first main surface, extending in both vertical and horizontal directions, wherein the main surfaces are the largest outer surfaces of the elevator door; and a first end surface connecting the first main surface to the second main surface and extending vertically and perpendicularly to the main surfaces, wherein a first set of first light sources is arranged at the first end surface of the elevator door. Arranging the first set of light sources at the first end surface can help make the light sources invisible to passengers when the elevator door is closed. Furthermore, when the elevator door is open, the light sources can be turned off, making the visibility of the light sources very low in the open state of the elevator door, and can help at least some passengers not even be aware of the presence of the light sources. In the case where the elevator door is a telescopic door with two or more door panels, the main surface can extend to all panels, and the end surface is one end surface of the elevator door, particularly one end surface of one of the outermost panels of the elevator door.

[0022] According to one embodiment, a first light source is arranged such that its main emission direction is perpendicular to a first end surface, in which light is primarily emitted from the first light source. Alternatively, the first light source is arranged such that its main emission direction is parallel to the first end surface. The main emission direction may be defined by the center of a beam emitted from a respective light source. The main emission direction may be perpendicular to the light-emitting surface of the respective light source. When the first light source is arranged such that its main emission direction is perpendicular to the first end surface, and two doors are arranged for opening or closing the elevator shaft, the light source can directly illuminate the other elevator door opposite the one with the light source. Alternatively, when only one elevator door is arranged for opening or closing the elevator shaft, the light source can directly illuminate the frame of the elevator shaft. As another alternative, the first light source may be arranged such that its main emission direction is perpendicular to the first end surface, and additionally, a reflector, such as a prism, may be arranged on the light source to redirect the light in a direction parallel to the first end surface.

[0023] According to one embodiment, the elevator door includes a scale comprising two or more numbers arranged on a first main surface, wherein each of the numbers indicates a floor of a building in which the elevator is located, and wherein each of the numbers is arranged horizontally close to a corresponding first light source among the first light sources.

[0024] According to one embodiment, the information includes one or more pieces of information from a set of information, said set including the current position of the car within the elevator shaft, the car's landing position within the shaft, and pending car calls. The current position of the car may correspond to the floor the car is currently positioned at. The landing position of the car may correspond to the floor the car is positioned at the end of its current journey. For example, the landing position may be the target floor the car is next to move to. The pending call may represent the floor from which one of the passengers currently requesting the car, either inside the car or waiting at the floor where the car was called, is currently requesting the car's floor.

[0025] According to one embodiment, a first light source is configured to emit light having at least two different colors, wherein the first color of the different colors indicates first information in the information, and the second color of the different colors indicates second information in the information. For example, each light source is configured to emit light having two different colors (e.g., green and red), wherein each light source may include only one light-emitting element, such as an LED or OLED, configured to emit light of the two different colors, or each light source may include one light-emitting element for one of the colors and another light-emitting element for the other color. For example, red light may be assigned to information about the current position of the car. Alternatively or additionally, green light may be assigned to information about the car's landing position or pending calls. For example, when the elevator door is a car door, green light may be assigned to information about pending calls, and / or when the elevator door is a landing door, green light may be assigned to information about the car's landing position.

[0026] According to one embodiment, the car includes a second door having: a third main surface extending in both vertical and horizontal directions; a fourth main surface opposite to the third main surface, extending in both vertical and horizontal directions; and a second end surface connecting the third main surface to the fourth main surface and extending vertically and perpendicular to both the third and fourth main surfaces, wherein the third and fourth main surfaces are the largest outer surfaces of the second door, and the first and second doors are arranged such that the first and second end surfaces face each other. In this context, the second door is the second car door of the car and may be referred to as the second car door.

[0027] According to one embodiment, the second door includes a second set of two or more second light sources arranged vertically above and below each other, wherein the second light sources are configured to indicate at least one piece of information regarding the current travel of the car. The second set of light sources can be configured as a first set of light sources. The second set of second light sources can be arranged at the second end surface of the second door. There can be one second light source for each first light source, such that a corresponding second light source is arranged at each horizontal position of the first light source. Therefore, the first light source can face the corresponding second light source among the second light sources.

[0028] According to one embodiment, the second door includes at least one reflector disposed at a second end surface of the second door, such that light emitted from one or more first light sources of the first door is reflected by the reflector of the second door. The reflector may extend over the entire height of a first set of first light sources. Alternatively, there may be two or more reflectors, for example, one reflector for each first light source, such that a corresponding reflector is disposed at each horizontal position of the first light source. Thus, the first light source may face the corresponding reflector in the reflector. The reflectors may be arranged as a supplement to or alternative to a second set of second light sources.

[0029] According to one embodiment, each of the elevator doors at the shaft opening is configured as a landing door, and the elevator includes a car with one or two elevator doors as described above, wherein each of the elevator doors of the car is configured as a car door. Therefore, when the car is positioned at a door opening in one of the floors, the corresponding doorway can be opened or closed by at least one of the car doors and at least one of the landing doors, wherein the car door and / or landing door can be configured according to a first door and optionally a second door. In this case, the corresponding car door and the corresponding landing door can move together to open or close the corresponding doorway, for example, simultaneously opening or closing the corresponding doorways. This movement can be controlled by a control unit.

[0030] According to one embodiment, the light source is activated when one or more elevator doors are closed, and deactivated when one or more elevator doors are open. Therefore, when the elevator doors are closed, the light from the light source can escape from the gap between the respective first and second doors and can be perceived by passengers in front of the elevator doors, while when the elevator doors are open, the light source is less visible and less obstructive to the passenger's view. In the case where the light source is positioned at the corresponding end surfaces of the opposing first and second doors, when the elevator doors are closed, the light from the light source illuminates the opposing door; or, in the case of only one elevator door (i.e., the first door), it illuminates the frame of the elevator doorway, while when the elevator doors are open, the deactivated light source is almost invisible. This can contribute to a positive passenger experience.

[0031] According to one embodiment, the light source brightens during the closing movement of one or more elevator doors, causing the light source to emit more and more light as the one or more elevator doors close. Alternatively or additionally, the light source dims during the opening movement of one or more elevator doors, causing the light source to emit less and less light as the one or more elevator doors open.

[0032] According to one embodiment, when one or more elevator doors are open, all light sources except the lowest one are deactivated. This allows the lowest light source to illuminate the elevator door threshold and / or the gap between the elevator car and the building within the elevator doorway. This can help ensure that the elevator door threshold and / or gap are visible to passengers. This can help prevent passengers from tripping when passing through the elevator doorway. This can contribute to passenger safety. Attached Figure Description

[0045] The accompanying drawings are schematic only and are not drawn to scale. The same reference numerals refer to the same or similar features. Detailed Implementation

[0046] Figure 1 A cross-sectional side view of an elevator 1 according to an embodiment of the technology described herein is shown. The elevator 1 can be configured to transport one or more passengers and / or goods from one floor 10 of a building to another floor 10. The building has an elevator shaft 3 in which a car 5 of the elevator 1 is movably arranged. The car 5 is displaceably arranged (e.g., vertically) in the shaft 3. The car 5 is mechanically connected to a counterweight 2 of the elevator 1 via at least one suspension element 4 (e.g., a rope). The suspension element 4 can be guided between the car 5 and the counterweight 2 via one or more deflection rollers 12. The suspension element 4, and therefore the car 5 and the counterweight 2, can be moved by means of a motor (not shown) of the elevator 1, thereby enabling the displacement of the car 5. The motor can be controlled by means of an elevator control unit 16. For example, the elevator control unit 16 can be arranged at or above the top of the shaft 3.

[0047] The car 5 can be configured to accommodate one or more passengers and / or one or more loads to be transported. The car 5 has a car opening 6 through which passengers can enter or exit the car 5, or through which loads can be placed into or removed from the car 5. The car 5 has at least one car door 7, namely a first door 22 (see...). Figures 2 to 9The elevator 1 includes a car door actuator 8, mechanically coupled to the car door 7, allowing the car door 7 to move horizontally. The elevator 1 may include a car door actuator 8, which is mechanically coupled to the car door 7, allowing the car door 7 to move by means of the car door actuator 8, specifically opening or closing. Such mechanical couplings are known from the prior art. The elevator 1 may include a car control unit 14, communicatively coupled to the car door actuator 8, allowing the car door actuator 8 to be controlled by means of the car control unit 14. Specifically, the car control unit 14 may be communicatively coupled to the car door actuator 8, allowing the car control unit 14 to transmit control signals to the car door actuator 8, for example, wirelessly or via cable. Furthermore, the car control unit 14 may be communicatively coupled to the elevator control unit 16, for example, via wires or wirelessly.

[0048] The elevator shaft 3 includes shaft openings 9 at each of the floors 10, through which the elevator car 5 can enter or exit to provide an entrance to the corresponding floor 10 of the building from which the elevator car 5 begins. At least one landing door 11, such as a first door 22 (see...). Figures 2 to 9 The elevator car 5 can be positioned at each of these shaft openings 9. The landing door 11 is mechanically and horizontally movable to the building on the corresponding floor 10. If the elevator car 5 is located on one of the floors 10, the corresponding shaft opening 9 can be positioned opposite the car door opening 6. With the car door 7 open and the landing door 11 open, the elevator car 5 can then enter or exit the corresponding floor 10 through the shaft opening 9 and the car door opening 6, passing through the elevator 1's doorway 20. Within the doorway 20, there may be a gap between the elevator car 5 and the shaft 3 and / or a threshold (not shown).

[0049] Therefore, each of the elevator doors at the shaft opening 9 is one of the landing doors 11, and each of the elevator doors of the car 5 is one of the car doors 7. Thus, when the car 5 is positioned in one of the floors 10, the corresponding doorway 20 can be opened or closed by at least one of the car doors 7 and at least one of the landing doors 11. In this case, the corresponding car door 7 and the corresponding landing door 11 can move together to open or close the corresponding doorway 20, for example, simultaneously.

[0050] Elevator 1 may include a shaft door actuator 13 and a floor control unit 19. The shaft door actuator 13 may be mechanically coupled to a landing door 11, allowing the landing door 11 to move, specifically open or close, by means of the shaft door actuator 13. Such mechanical couplings are known from the prior art. The floor control unit 19 may be communicatively coupled to the shaft door actuator 13, allowing the shaft door actuator 13 to be controlled by means of the floor control unit 19. Specifically, the floor control unit 19 may be communicatively coupled to the shaft door actuator 13, allowing the floor control unit 19 to transmit control signals to the shaft door actuator 13, for example, wirelessly or via wires. Furthermore, the floor control unit 19 may be communicatively coupled to a car control unit 14 and / or an elevator control unit 16, for example, via wired or wireless means. Specifically, the car control unit 14 and the floor control unit 19 may be coupled to the elevator control unit 16, allowing one or more control signals and / or sensor signals to be exchanged between the car control unit 14 and the elevator control unit 16 and / or between the floor control unit 19 and the car control unit 16. For example, elevator control unit 16 can be configured to start and / or stop the movement of car door 7 and / or landing door 11 via corresponding control units 14, 19.

[0051] The function of elevator 1 controlled by elevator control unit 16 can be, for example, any function relating to the movement of car 5 and / or elevator doors 7, 11. For example, this function could be the movement of car 5, such as movement in the vertical direction. This function can be controlled by elevator control unit 16 via a motor for lifting car 5. Alternatively or additionally, this function could be the movement of one or more elevator doors 7, 11 of car 5 or the hoistway 3.

[0052] At least one of elevator doors 7 and 11, such as car door 7 and all landing doors 11, includes a first set 24 of two or more first light sources 26 (see...). Figure 2 (and subsequent accompanying diagrams), when the corresponding elevator doors 7 and 11 are oriented as intended for their purpose (e.g. Figures 1 to 5 , Figure 8 and Figure 9 As shown, a first set 24 of two or more first light sources 26 is arranged vertically above and below each other, wherein the first light sources 26 are configured to indicate at least one piece of information regarding the current travel of the car 5. At least one of the control units 14, 16, and 19 is communicatively coupled to the first light source 26. For example, the car control unit 14 is coupled to the first light source 26 at the car door 7, and the floor control unit 19 is coupled to the first light source 26 at the corresponding floor door 11. The control units 14, 16, and 19 are configured to activate or deactivate one or more of the corresponding light sources 26 so as to display one or more pieces of information regarding the current travel of the car 5 accordingly through the first light source 26.

[0053] When a call is made to car 5 from one of the floors 10 of the building, the current journey of car 5 may begin. The current journey of car 5 may stop when the last passenger has disembarked from car 5 and there are no pending calls from another floor 10 of the building. During the current journey of car 5, car 5 may be called from one or more floors 10, car 5 may be moved to one or more floors 10 based on pending calls, and / or car 5 may be moved to a floor 10 that was called from inside car 5.

[0054] This information can be determined by the car and / or floor control units 14, 16 coupled to the corresponding first light source 26. In this case, the corresponding control units 14, 16 can be coupled to several sensors capable of detecting the current position of the car 5, the location from which the car 5 was called, and / or which floor 10 has been selected as the landing floor. Alternatively, this information can be sent from the elevator control unit 16 to one or both of the car and / or floor control units 14, 19, which are coupled to the sensors and configured to control the movement of the car 5 through the hoistway 3.

[0055] The information may include one or more pieces of information from a set of information. This set of information may include the current position of car 5 within the shaft 3 of elevator 1, the landing position or floor of car 5 within the shaft 3, and pending car calls. The current position of car 5 may correspond to the floor 10 where car 5 is currently positioned. The landing position and / or floor of car 5 may correspond to the floor 10 where car 5 is positioned at the end of its current journey. For example, the landing position may be the target floor within floor 10 that car 5 is next to move to. A pending call may indicate that one of the passengers waiting in car 5 or at the floor 10 from which they called car 5 is currently waiting from that floor within the floor 10 from which they requested car 5.

[0056] For ease of explanation, throughout this specification it is assumed that the elevator doors 7, 11, and all other elevator doors described above and below are oriented as intended for their intended use, as shown in the figures. In this context, this may mean that, in the case of an elevator door being one of the landing doors 11, the elevator door 11 is located in one of the floors 10 of the building at the corresponding shaft opening 9, or, in the case of an elevator door being car door 7 of car 5, the elevator door is located in car 5.

[0057] Figure 2 A perspective view of a first door 22 according to an embodiment of the technology described herein is shown. The first door 22 can be one of the elevator doors. For example, when elevator doors are arranged at car 5, the first door 22 can be car door 7, and in particular, the first car door 62 (see...). Figure 6 and Figure 7 Alternatively, when the first door 22 is located at one of the shaft openings 9 in one of the floors 10, the first door 22 may be one of the landing doors 11, particularly the first landing door 66 (see...). Figure 6 and Figure 7 Optionally, elevator 1 includes at least one car door 7, namely a first car door 62, and at least one landing door 11, namely a first landing door 66, the at least one landing door being located, for example, on each floor 10 of the building. Each of the elevator doors may be a single door or a telescopic door with two or more door panels. The closing direction 38 of the elevator doors is parallel to the horizontal direction.

[0058] An elevator door, specifically a first door 22, includes a first main surface 32, a second main surface 33, and a first end surface 36. The first main surface 32 extends in both vertical and horizontal directions. The second main surface 33 is arranged opposite to the first main surface 32. The second main surface 33 may extend in both vertical and horizontal directions, wherein the main surfaces 32 and 33 are the largest outer surfaces of the first door 22. The first end surface 36 connects the first main surface 32 to the second main surface 33 and extends vertically and perpendicular to the main surfaces 32 and 33. The first end surface 36 is the front surface of the first door 22 in the closing direction 30. The first door 22 has a bottom surface facing the bottom and a top surface 34 facing away from the bottom, wherein the bottom surface and the top surface 34 are perpendicular to the main surfaces 32 and 33 and the first end surface 36. The first door 22 has another end surface opposite to the first end surface 36, wherein this other end surface is not visible when the first door 22 is arranged in the doorway 20, which is intended for its purpose.

[0059] Preferably, the first set 24 of the first light source 26 is arranged at the first end surface 36 of the first door 22. However, the first set 24 of the first light source 26 may alternatively be arranged at one of the main surfaces 32, 33. In the case that the first door 22 is a telescopic door with two or more door panels, the main surfaces 32, 33 may extend over all the panels, and the first end surface 36 may be the end surface of one of the panels, particularly the end surface of one of the outermost panels of the first door 22.

[0060] The first light sources 26 can be distributed across the entire height of the first door 22, such that at least one of the first light sources 26 is arranged near the bottom of the first door 22, and at least one of the first light sources 26 is arranged near the top surface 34 of the first door 22. In this case, when the first door 22 is opened, the first light source 26 near the bottom can be used to illuminate the threshold of the doorway 20 or the gap between the car 5 and the building within the doorway 20.

[0061] For example, each of the first light sources 26 may include one or more LEDs or OLEDs. The first light source 26 may be a light-emitting component of an LED strip, wherein the LED strip may be arranged at the first gate 22. The first set 24 of the LED strip and / or the first light source 26 may be a component attached to a lamp panel of the first gate 22.

[0062] The first light source 26 can be configured to emit light having at least two different colors. The first color of the different colors can indicate first information in the information, and the second color of the different colors can indicate second information in the information. For example, each of the first light sources 26 can be configured to emit light having two different colors (e.g., green and red), wherein each of the first light sources 26 can include only one light-emitting element, such as an LED or OLED, configured to emit light of the two different colors. Alternatively, each of the first light sources 26 can include one light-emitting element for one color and another light-emitting element for the other color.

[0063] Optionally, there are no buttons or switches, such as those for selecting floor levels, located at elevator doors 7, 11, and / or coupled to the light source 26. Corresponding keypads including such buttons or switches may be located on the walls of each floor 10 of the building and / or on the walls of the car body or shell of the car 5. Therefore, it is possible that the first set 24 of the first light sources 26 cannot be used as a control element for controlling the movement of the car 5. Instead, it is possible that the first set 24 of the first light sources 26 may be used only to provide information associated with the respective first light source 26 and / or the color of the light emitted by the respective first light source 26.

[0064] Optionally, the first door 22 may include a scale 28 comprising two or more numbers arranged on the first main surface 32. Each number may indicate one of the floors 10 of the building. Each of the numbers may be arranged horizontally adjacent to a corresponding first light source 26, such that each number is assigned to one of the light sources 26. In the example shown in the figure, the scale 28 includes "E" representing the ground floor of the building and numbers "1" through "9" for the other nine floors of the building. However, this is only an example, and the numbering can be easily adapted to the actual number of floors 10 of the building in which the elevator 1 is located.

[0065] Figure 3 Embodiments of the technology described herein are shown. Figure 2 Perspective view of the first door and the second door 42. The first door 22 and the second door 42 can be configured as car door 7 or landing door 11. For example, the first door 22 can be a first car door 62, and the second door 42 can be a second car door 64 (see Figure 6 and Figure 7 Alternatively, the first door 22 may be the first-level station door 66, and the second door 42 may be the second-level station door 68 (see...). Figure 6 and Figure 7 ).

[0066] The second door 42 may have a third main surface 54, a fourth main surface 56, and a second end surface 48. The third main surface 54 extends in both vertical and horizontal directions. The fourth main surface 56 may be arranged opposite to the third main surface 54. The fourth main surface 56 may extend in both vertical and horizontal directions. The second end surface 48 may connect the third main surface 54 to the fourth main surface 56. The second end surface 48 may extend vertically and perpendicular to the third main surface 54 and the fourth main surface 56. The third main surface 54 and the fourth main surface 56 may be the largest outer surfaces of the second door 42. The first door 22 and the second door 42 may be arranged such that the first end surface 36 and the second end surface 48 face each other.

[0067] The second door 42 may include a second set 44 of two or more second light sources 46, the second set 44 of which are arranged vertically above and below each other. The second light sources 46 may be configured to indicate at least one piece of information regarding the current travel of the car 5. The second set 44 of the second light sources 46 may be configured as a first set 24 of first light sources 26. The second set 44 of the second light sources 46 may be arranged at the second end surface 48 of the second door 42. Each first light source 26 may have one second light source 46, such that a corresponding second light source 46 is arranged at each horizontal position of one of the first light sources 26. Thus, the first light source 26 may face the corresponding light source among the second light sources 46.

[0068] Figure 4 Embodiments of the technology described herein are shown. Figure 2 Perspective view of the first door 22 and the second door 42. Figure 4 The second gate 42 shown can broadly correspond to the information about Figure 3 The second section, 42, is described. Therefore, for the sake of brevity, only the section 42 will be described below. Figure 4 The second door 42 shown is Figure 3 The second gate 42 shown has those features that are different from those of the second gate 42.

[0069] The second gate 42 may include at least one reflector 50 disposed at the second end surface 48 such that light emitted from one or more first light sources 26 of the first gate 22 is reflected by the reflector 50 of the second gate 42. The reflector 50 may extend over the entire height of the first set 24 of the first light sources 26. Alternatively, two or more reflectors 50 (not shown) may be present, for example, one reflector for each first light source 26, such that a corresponding reflector 50 is disposed at each horizontal position of one of the first light sources 26. Thus, the first light source 26 may face the corresponding reflector among the reflectors 50. The reflectors 50 may be arranged as a supplement to or alternative to the second set 44 of the second light sources 46.

[0070] Figure 5 A perspective view of a first gate 22 according to an embodiment of the technology described herein is shown. Figure 5 The first gate 22 shown can broadly correspond to the information about Figure 2 The first section, 22, is described. Therefore, for the sake of brevity, only the following section will describe... Figure 5 The first door 22 shown is Figure 2 The first gate 22 shown has those features that are different from the first gate 22.

[0071] The first light source 26 may be arranged only within the vertically extending section 52 of the first door 22. This section 52 may be much smaller than the height of the first door 22. For example, the section 52 may extend approximately half or a quarter of the height of the first door 22. For example, the section 52 may be positioned at a height corresponding to the eye level of an average adult passenger.

[0072] Figure 6 A cross-sectional top view of the elevator 1's doorway 20, two car doors 7, and two landing doors 11, according to an embodiment of the technology described herein, is shown. In particular, Figure 6 A door frame 60, fixedly connected to the building, is shown. The door frame 60 is arranged in one of the floors 10 and at least partially surrounds the corresponding shaft opening 9. Furthermore, Figure 6 A portion of the car 5 is shown, which at least partially surrounds the car opening 6. The car 5 includes a first car door 62 and a second car door 64, the first car door 62 being configurable as a first door 22 and / or a car door 7, and the second car door 64 being configurable as a second door 42 and / or a car door 7. A first landing door 66, configurable as a first door 22 and / or a landing door 22, and a second landing door 68, configurable as a second door 42 and / or a landing door 11, are sandwiched between the car doors 62, 64 and the door frame 60.

[0073] Car doors 62 and 64 are arranged such that they can move toward each other in the closing direction 38 to close car opening 6, and can move away from each other in the opposite direction to open car opening 6. For example, car doors 62 and 64 can move simultaneously to open or close car opening 6. Landing doors 66 and 68 are arranged such that they can move toward each other in the closing direction 38 to close hoistway opening 9, and can move away from each other in the opposite direction to open hoistway opening 9. For example, landing doors 66 and 68 can move simultaneously to open or close hoistway opening 9. Doorway 20 can be opened by (e.g., simultaneously) opening car doors 62 and 64 and landing doors 66 and 68. Doorway 20 can be closed by (e.g., simultaneously) closing car doors 62 and 64 and landing doors 66 and 68.

[0074] The first light source 26 can be arranged such that the main emission direction 70 is perpendicular to the first end surface 36, along which light is mainly emitted from the first light source 26. The main emission direction 70 can be defined by the center of the light beam emitted from the corresponding first light source 26. The main emission direction 70 can be perpendicular to the light emitting surface of the corresponding first light source 26.

[0075] When both car doors 62 and 64 are arranged to open or close the car door opening 6, the first light source 26 at the first car door 62 can directly illuminate the second end surface 48 of the second car door 42. Alternatively, when only the first car door 62 is arranged to open or close the car door opening 6, the first light source can directly illuminate the frame of the car door opening 6. When both landing doors 66 and 68 are arranged to open or close the hoistway opening 9, the first light source 26 at the first landing door 66 can directly illuminate the second end surface 48 of the second landing door 68. Alternatively, when only the first landing door 66 is arranged to open or close the hoistway opening 9, the first light source 26 can directly illuminate the frame 60 of the doorway 20.

[0076] The second car door and / or landing door 64, 68 can be configured to... Figure 3 The second door 42 is described, and may include a second set 44 of a second light source 46. Alternatively, the second car door and / or landing doors 64, 68 may be configured to... Figure 4 The second door 42 is described, and may include a reflector 50 and optionally only include a second set 44 of second light sources 46. Furthermore, each of elevator doors 62, 64, 66, and 68 may correspond to... Figure 5 The first gate 22 is configured such that the first set 24 and / or the second set 44 of the first light source 26 and / or the second light source 46 and / or the reflector 50 are arranged only in the segment 52.

[0077] Figure 7 A cross-sectional top view of the elevator 1, including the doorway 20, two car doors 62, 64, and two landing doors 66, 68, according to an embodiment of the technology described herein, is shown. Figure 7 The elevator doors 62, 64, 66, and 68 shown can broadly correspond to the information about Figure 6 Elevator doors 62, 64, 66, and 68 are described. Therefore, for the sake of brevity, only these are described below. Figure 7 Elevator doors 62, 64, 66, and 68 shown are... Figure 6 The elevator doors 62, 64, 66, and 68 shown have those characteristics of different elevator doors 62, 64, 66, and 68.

[0078] from Figure 7 It can be seen that the first light source 26 can be arranged such that the main emission direction 70 is parallel to the first end surface 36. Therefore, the first light source 26 can be arranged such that the main emission direction 70 is directed towards the passengers inside the car 5 or the passengers waiting in the car 5.

[0079] Figure 8 A front view of two of the landing doors 11, 66, 68 according to an embodiment of the technology described herein is shown. As described above, the first light source 26 can be configured to emit light having at least two different colors, wherein a first light 72 of a first color indicates first information, and a second light 74 of a second color indicates second information. The second light source 46 can also be configured similarly. For example, each of the first light source 26 and / or the second light source 46 can be configured to emit light having two different colors (e.g., green and red). For example, the first light 72 can be red and can be assigned to first information, such as the current position of the car 5. Alternatively or additionally, the second light 74 can be green and can be assigned to second information, such as the landing position of the car 5 or an pending car call. For example, when the elevator door is one of landing doors 66, 68, the green second light 74 can be assigned to information about the landing position of the car 5.

[0080] Therefore, in Figure 8 In the example shown, the first light source 26 assigned to number "8" in scale 28 emits a first light 72 representing information that the car 5 is currently located on the 8th floor 10, while the first light source 26 assigned to number "2" in scale 28 emits a second light 74 representing information that the current floor position of the car 5 is the 2nd floor 10.

[0081] However, as an alternative, light sources 26 and 46 can emit light of other colors, and / or other information can be assigned to the corresponding light. Furthermore, more or fewer than two different colors can be used to represent the information to be displayed.

[0082] exist Figure 8 In the illustrated case, landing doors 66 and 68 are closed. In this closed state, landing doors 66 and 68, particularly their end surfaces 36 and 48, can contact each other, with the gap between landing doors 66 and 68 only for illustrative purposes. Figure 8 As shown in the diagram. In reality, gaps may or may not exist. However, even when the landing doors 66 and 68 are closed and even when there are no gaps, the light emitted from the light sources 26 and 46 can be directed toward passengers waiting in front of the landing doors 66 and 68 on the corresponding floors 10 and / or reflected off the passageway 20.

[0083] When light emitted from light sources 26 and 46 such that the main emission direction 70 is perpendicular to the corresponding end surfaces 36 and 48, as per the relevant information... Figure 6 As described, light sources 26 and 46 may not be visible when the landing doors 66 and 68 are closed.

[0084] Figure 9 A front view of two car doors 7, 62, 64 according to an embodiment of the technology described herein is shown. Figure 9 The car doors 7, 62, and 64 shown can broadly correspond to the information about Figure 8 The landing doors 11, 66, and 68 are described. Therefore, for the sake of brevity, only the features of car doors 7, 62, and 64 will be described below, where... Figure 9 The car doors 62 and 64 shown are Figure 8 The floor doors 66 and 68 shown are different.

[0085] In the case where one or more elevator doors are car doors 62, 64, the first light 72 may also be red and may be assigned to first information, such as the current position of car 5. Furthermore, the second light 72 may also be green, but may be assigned to information about pending car calls.

[0086] Therefore, in Figure 9 In the example shown, the first light source 26 assigned to, for example, number "2" in scale 28 emits a first light 72 representing information that car 5 is currently located on the second floor 10, while the first light source 26 assigned to, for example, numbers "E", "5" and "9" in scale 28 emits a second light 74 representing information that there is an pending car call from floors "E", "5" and "9".

[0087] However, as an alternative, light sources 26 and 46 can emit light of other colors, and / or other information can be assigned to the corresponding light. Furthermore, more or fewer than two different colors can be used to represent the information to be displayed.

[0088] exist Figure 9In the illustrated case, car doors 62 and 64 are closed. In this closed state, car doors 62 and 64, particularly their end surfaces 36 and 48, can contact each other, wherein the gap between car doors 62 and 64 is only for illustrative purposes. Figure 9 As shown in the diagram. In reality, gaps may or may not exist. However, even when the car doors 62 and 64 are closed and even when there are no gaps, light emitted from light sources 26 and 46 can be directed toward and / or reflected off the aisle 20 towards passengers traveling inside the car 5.

[0089] When light emitted from light sources 26 and 46 such that the main emission direction 70 is perpendicular to the corresponding end surfaces 36 and 48, as per the relevant information... Figure 6 As described, the light sources 26 and 46 themselves may not be visible when the car doors 62 and 64 are closed.

[0090] Figure 10 A flowchart illustrating a method for displaying information at or within elevator 1 according to an embodiment of the technology described herein is shown. The method may be executed by one or more controllers 14, 16, 19, wherein the respective controllers 14, 16, 19 may perform these steps independently or in cooperation with one of the other controllers 14, 16, 19.

[0091] In step S2, one or more pieces of information about the current journey of car 5 can be determined. For example, it can be determined where car 5 is currently located, where car 5 was currently called from, and / or which floor 10 is the next landing location of car 5.

[0092] In step S4, two or more light sources among the light sources 26, 46 of the corresponding elevator doors of elevator 1 are activated or deactivated based on the determined information, wherein the corresponding elevator door is at least one of one or more car doors 7, 62, 64 and / or landing doors 11, 66, 68 and / or first door 22 and / or second door 42. Preferably, the information is displayed at one or more car doors 7, 62, 64 and all landing doors 11, 66, 68, wherein the information provided by one or more car doors 7, 62, 64 may differ from the information provided by landing doors 11, 66, 68, such as regarding... Figure 8 and Figure 9 As explained.

[0093] Optionally, in step S4, the light sources 26 and 46 can be activated when the corresponding elevator door(s) are closed, and can be deactivated when the corresponding elevator door(s) are open.

[0094] Alternatively or additionally, in step S4, the light sources 26 and 46 may brighten during the closing movement of the respective elevator door(s), such that the light sources 26 and 46 emit more and more light as the respective elevator door(s) close. Alternatively or additionally, in step S4, the light sources 26 and 46 may dim during the opening movement of the respective elevator door(s), such that the light sources 26 and 46 emit less and less light as the elevator door(s) open.

[0095] Alternatively, in step S4, when the corresponding elevator door(s) open, light sources 26, 46 can be deactivated except for the lowest light source(s) among light sources 26, 46. In this case, when the corresponding elevator door opens, the corresponding lowest light source among light sources 26, 46 illuminates the threshold and / or gap in the doorway 20.

[0096] Figure 11 Embodiments of the technology described herein are shown. Figure 1 Perspective view of the first door 22 of elevator 1. Figure 11 The first gate 22 shown can broadly correspond to the information about Figure 2 The first section, number 22, is explained. Therefore, the following text will only explain... Figure 11 The first door 22 shown is with Figure 2 The first gate 22 shown is different Figure 11 The features of the first gate 22 shown.

[0097] The first door 22 may include a reflector 50, wherein in this embodiment, the reflector 50 and the first light source 26 are arranged on the same door and are implemented as a prism that redirects light emitted by the light source to approximately 90°, such that light is emitted from the reflector 50 parallel to the first end surface 36. This light emission direction corresponds to... Figure 7 The direction of light emission is explained, where the first set of light sources 24 can be as follows: Figure 6 The arrangement shown, wherein the reflector 50 will emit light as... Figure 7 The redirection is shown.

[0098] This invention is not limited to the embodiments described above. For example, these embodiments can be combined and / or modified without departing from the scope of the invention as defined by the independent claims. In particular, in the above description, the first door 22 is always the elevator door located on the left when viewed from one of the passengers in front of the respective elevator door, and the first end surface 36 is arranged on the right side of the first door. However, in an alternative embodiment, the first door 22 may be the elevator door located on the right when viewed from one of the passengers in front of the respective elevator door, and the first end surface 36 may be arranged on the left side of the first door 22. Furthermore, the sets 24, 44 of light sources 26, 46 may include more or fewer light sources 26, 46, for example, depending on the number of floors 10 in the building, wherein the scale 28 may be adapted accordingly. Furthermore, the sets 24, 44 of light sources 26, 46 may be arranged at the first main surface 32 and / or the third main surface 54, rather than at the end surfaces 36, 48. In addition, light sources 26 and 46 can be configured to display only one or more colors and / or to emit light of different colors (e.g., blue, white, yellow, etc.).

[0099] Finally, it should be noted that the term "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude multiple. Elements described in association with different embodiments may also be combined. It should also be noted that reference numerals in the claims should not be construed as limiting the scope of the claims.
