DETAILED DESCRIPTION OF THE INVENTION

[0097] Corresponding or identical parts are provided with the same reference numerals in the figures.

[0098] Referring now to the figures of the drawings in detail and first, particularly to FIG. 1 thereof, there is shown a schematic illustration of a control and information system 1 which is integrated in a system architecture. The system architecture include an aircraft 2 with an on-board computer and a compartment 3 which is in the form of a washroom, shower room or changing room for passengers and/or staff members or a rest room for the crew of the aircraft. The compartment 3 is integrated in a cabin of the aircraft 2. The compartment 3 is connected to a power supply of the aircraft 2 and connected to the aircraft 2, in particular to the on-board computer, via a data bus in technical signal terms.

[0099] According to FIG. 4, the compartment 3 has a door 4 which is arranged in a wall structure 45 which at least partially surrounds the compartment 3. The door 4 is in the form of a folding door with an external door leaf 30a and with an internal door leaf 30b. The external and internal door leaves 30a, 30b are pivotably connected to each other via at least one hinge device 31. The internal door leaf 30b adjoins the external door leaf 30a of the folding door, wherein the external door leaf 30a adjoins a wall portion 44 of the wall structure 45 of the compartment 3 and can be pivoted relative to it. Via the door 4, the compartment 3 can be entered and left again.

[0100] The control and information system 1 is constructed to control the door 4 and to exchange information items about the compartment 3. It contains a door actuator 5, a lock actuator 6, a control device 7 with an evaluation device 8. The control device 7 is connected to the power supply of the aircraft 2 and connected to the aircraft 2, in particular to the on-board computer, via the data bus.

[0101] The lock actuator 6 forms together with a locking apparatus 43 a component of a locking arrangement 9 which is a component of the control and information system 1 and which is shown in FIGS. 4 to 6. The locking arrangement 9 is constructed to lock and block the movement of the door 4. The lock actuator 6 is constructed to actuate the locking apparatus 43. Alternatively, the locking apparatus 43 can be manually actuated by a user 15, by a crew member 16 and/or additional staff members 17 of the aircraft 2. The additional staff members 17 are, for example, cleaning or service operators who are present in the aircraft 2 during a downtime of the aircraft 2 on the ground.

[0102] The control and information system 1 contains a first human/machine interface 10. The first human/machine interface 10 is arranged at a first side of the door 4 inside the compartment 3. The first human/machine interface 10 contains at least one first sensor device 12a with at least one sensor which is an optical proximity sensor or a capacitive proximity sensor or a time-of-flight sensor. The first human/machine interface 10 comprises a first display device 13a which is in the form of a monitor or display. The first display device 13a contains a touch screen, on which inputs can be carried out and on which displays and/or audio outputs can be output. The first human/machine interface 10 is connected to a store 14 and has a communication interface 21.

[0103] The control and information system 1 contains a second human/machine interface 11 which is arranged at another side of the door 4 outside the compartment 3. The second human/machine interface 11 contains at least one second sensor device 12b with at least one sensor which is an optical or capacitive proximity sensor or a time-of-flight sensor. The second human/machine interface 11 comprises a second display device 13b which is in the form of a monitor or display. The second display device 13b contains a touch screen, on which inputs can be carried out and on which displays and/or audio outputs can be output. The first and the second human/machine interfaces 10, 11 use the store 14 and the communication interface 21 together.

[0104] The user 15 of the door 4, the crew 16 and additional staff members 17 are present in the system structure. The crew 16, the additional staff members 17 and the on-board computer of the aircraft 2 form an authorized location 22 inside the system structure.

[0105] The user can unlock and/or open the door 4 as an incoming user 15 from outside the compartment 3 in order to enter the compartment 3. This can be carried out by manually actuating the locking apparatus 43 of the locking arrangement 9 (FIGS. 4 to 6). Alternatively, since the second human/machine interface 11 and the door actuator 5 are provided, the second sensor device 12b detects a triggering action 18b of the incoming user 15.

[0106] As a leaving user 15 who is leaving the compartment 3 through the door 4, the user 15 can unlock and open the door 4 from inside the compartment 3 in order to leave the compartment 3. To this end, the first sensor device 12a detects the triggering action 18a of the leaving user 15. The crew 16 and/or the additional staff members 17 can also carry out the triggering action 18a, 18b accordingly as humans similar to the user 15 and not in the capacity as an authorized location 22. In other words, they can use the compartment in the same manner as a “normal” user 15.

[0107] The triggering action 18a, 18b is an approach by the user 15, the crew 16 and/or the additional staff members 17 toward the sensor device 12a, 12b if it comprises at least one proximity sensor. The triggering action 18a, 18b is alternatively a gesture 20 in front of the sensor device 12a, 12b. The gesture 20 may be a wiping movement with the hand by the user 15, the crew 16 and/or the additional staff members 17 in front of the time-of-flight sensor, as shown in FIG. 2. Alternatively or optionally additionally, the triggering action 18a, 18b can be carried out by a corresponding input of the user 15a, 15b, the crew 16 and/or the additional staff members 17 on the touch pad of the display device 13a, 13b.

[0108] The respective sensor device 12a, 12b transmits the triggering actions 18a, 18b as triggering signals 19a, 19b to the control device 7. The control device 7 can control the door actuator 5 on the basis of the respective triggering signal 19a, 19b in order to open the door 4. It can also control the lock actuator 6 on the basis of the triggering signal 19a, 19b in order to unlock the door 4 and to cancel a blocking of the movement of the door 4. On the basis of the respective triggering signal 19a, 19b, the control device 7 can control the door actuator 5 in order to close the door 4 and can control the lock actuator 6 in order to lock the door 4 and to block the door movement.

[0109] The lock actuator 6 contains a first position sensor 25 and a second position sensor 26 (see FIGS. 4 and 5). The first position sensor 25 detects a position of the door 4, particularly whether the door 4 is open, partially open or closed. The second position sensor 26 detects a position of a first actuation element 27, in this instance in the form of a bolt, of the lock actuator 6 (see FIGS. 5 and 6) and consequently whether the door 4 is locked and blocked in terms of the door movement or unlocked and movable.

[0110] The position of the door 4 is transmitted as a first position signal 28 and the position of the first actuation element 27 is transmitted as a second position signal 29 from the position sensor 25, 26 to the control device 7. The evaluation device 8 evaluates the first position signal 28 and the second position signal 29. The control device 7 controls the door actuator 5 during or after the transmission of the respective triggering signal 19a, 19b in accordance with the first position signal 28 in order to produce a torque for opening or closing the door 4. The control device 7 controls the lock actuator 6 during or after the transmission of the respective triggering signal 19a, 19b in accordance with the second position signal 29 in order to move the first actuation element 27 in translation in order to lock the door 4 by means of the locking apparatus 43 and to carry out the blocking of the movement of the door 4 or to unlock the door 4 and to cancel the blocking of the movement.

[0111] The control device 7 further controls the display device 13a, 13b which is relevant to the user 15, the crew 16 and/or the additional staff members 17 in order to display triggering actions 18a, 18b which are intended to be initiated. The triggering actions 18a, 18b which are intended to be initiated are particularly requests for the user 15, the crew 16 and/or the additional staff members 17 concerning measures which have to be carried out next. The control device 7 also controls the display device 13a, 13b in order to display the triggering actions 18a, 18b in particular as information items which the user 15, the crew 16 and/or the additional staff members 17 has/have already carried out. Furthermore, the control device 7 can control the display device 13a, 13b in order to display the current door status, particularly whether the door is open, closed, unlocked or locked.

[0112] The communication interface 21, by means of which information items can be transmitted between the control device 7 and the authorized location 22, is provided between the authorized location 22 which includes the on-board computer of the aircraft 2, the crew 16/the additional staff members 17—in this instance appearing as an authorized entity—the first human/machine interface 10 and the second human/machine interface 11. Input information items 23 can be communicated to the control device 7 from the authorized location 22 and/or output information items 24 can be transmitted from the control device 7 to the authorized location 22. It is also possible to have a mutual exchange of the input and output information items 23, 24.

[0113] The input information items 23 comprise instructions of the authorized location 22, in particular the crew 16, the additional staff members 17 and/or the on-board computer of the aircraft 2, by means of which access of the authorized location 22 to the control device 7 is ensured. The control device 7 can be caused by the authorized location 22 by means of the input information items 23 to control the door actuator 5 and/or the lock actuator 6 accordingly. This is carried out, for example, in accordance with flight phases, such as taxiing, take-off, landing and/or in the event of turbulence of the aircraft 2. The authorized location 22 can also transmit corresponding input information items 23 to the control device 7 in order to maintain and/or clean the compartment 3. Furthermore, the control device 7 can be deactivated by the authorized location 22 by means of the input information items 23, in particular switched to the powerless state, should this be necessary.

[0114] The authorized location 22 can input the input information items 23 via the touch screen of the display device 13a, 13b and transmit them to the control device 7. Via the touch screen and/or via the communication interface 21, the authorized location 22 can also store contents of files and/or storage media on the store 14 which can be called up by the control device 7. To this end, an authorization, for example, by entering a password, by the crew 16 and/or the additional staff members 17 may be provided. The authorization can be carried out via the touch screen or via a wireless connection, for example, near field communication, with the corresponding human/machine interface 10, 11, in particular via the communication interface 21. The control device 7 checks the authorization and enables the access of the authorized location 22, in particular the crew 16 and/or the additional staff members 17. By inputting such an authorization, therefore, the crew 16 and/or the additional staff members 17 become(s) the authorized location 22 or receives the functionality, access rights thereof, etc.

[0115] The output information items 24 can be output, in particular displayed, via the display device 13a, 13b or via the communication interface 21 to an external output device at the authorized location 22. For example, the contents of the files and/or the storage media which have been stored on the store 14 can be displayed as individual displays on the respective display device 13a, 13b.

[0116] The output information items 24 also include the implemented actions which the control device 7 has carried out as a result of the input information items 23. Thus, the output information items 24 can be output, in particular displayed, in the form of the door status and/or the actions which are intended to be initiated by the user 15.

[0117] The output information items 24 further include status messages concerning maintenance, servicing, defects and/or emergencies which are output on the respective display device 13a, 13b and/or the external output device of the authorized location 22. The status messages can be produced on the basis of an operating state of the control and information system 1. The operating state can be established in accordance with operating data of the door actuator 5 and/or the lock actuator 6 which are detected by the control device 7 and evaluated by the evaluation device 8.

[0118] The operating data can include operating times, a power consumption and/or a drive torque of the door actuator 5 and/or the lock actuator 6. The operating state can indicate, for example, on the basis of the established operating times, that the compartment has to be cleaned and/or maintained and/or that there is a defect of components of the control and information system 1. The conventional operating times of the compartment 3, which are stored in the control device 7, being exceeded can particularly indicate an emergency in the compartment 3 or a blocked door 4. As a result of the transmitted output information items 24, the authorized location 22 and also the user 15 can receive important messages and initiate corresponding measures.

[0119] FIG. 3 shows the door actuator 5 of the control and information system 1 as an exploded illustration. The door actuator 5 is constructed to open and close the door 4. A cutout of the internal door leaf 30b of the door 4 which is in the form of a folding door is also shown. The hinge device 31 and a coupling 32 are fitted in the internal door leaf 30b.

[0120] The door actuator 5 is mechanically connected to the door 4 via the coupling 32. Alternatively, the coupling 32 may be constructed so that the door 4 is mechanically connected to the wall structure 45 of the compartment 3 via the coupling 32 and the door actuator 5 is not thereby connected to the door 4. It is also possible for the coupling 32 to be able to be released from the wall structure 45 so that the door 4 can be removed from the wall structure 45.

[0121] The door actuator 5 contains a drive unit 33 having an electric motor and a gear mechanism, a housing 34, two sliding bearings 35 and a double cardan joint 36. The electric motor of the drive unit 33 is connected to the power supply of the aircraft 2. The double cardan joint 36 is actively connected to the hinge device 31. It transmits a torque which is generated by the electric motor to the hinge device 31 so that it is actuated, the internal door leaf 30b is pivoted relative to the external door leaf 30a (FIG. 4) and the door 4 carries out an opening or closing movement. The sliding bearings 35 are constructed to absorb transverse forces during the transmission of the torque by the double cardan joint 36 and allow exclusively a pivot movement of the hinge device 31.

[0122] FIG. 4 shows a perspective plan view of an inner side of the door 4 from an interior/inner space of the compartment 3. An installation situation of the locking arrangement 9 in the door 4 and in the wall structure 45 is schematically indicated by arrows which are directed in an additional stylized view of the compartment 3 (dashed box at the bottom right).

[0123] The locking arrangement 9 contains the lock actuator 6 and the locking apparatus 43. The locking apparatus 43 can be activated/operated by the lock actuator 6. The lock actuator 6 and the locking apparatus 43 are arranged one after the other and successively. They extend in the installation situation substantially horizontally and/or levelly relative to a base 40 of the compartment 3.

[0124] The wall structure 45 at least partially surrounds the compartment 3, wherein in the wall structure 45 the door 4 is arranged as a folding door. The wall structure 45 has the wall portion 44 which is arranged in abutment with the external door leaf 30a of the door 4. The external door leaf 30a is pivotable relative to the wall portion 44. The internal door leaf 30b is pivotably connected to the external door leaf 30a via the hinge device 31.

[0125] The lock actuator 6 is integrated in the wall portion 44. The locking apparatus 43 is integrated in the external door leaf 30a. The first human/machine interface 10 which is arranged on the wall portion 44 in the interior of the compartment 3 is also shown.

[0126] FIG. 5A shows a plan view of a front side V of the locking arrangement 9 and FIG. 5B shows a plan view of a rear side S of the locking arrangement 9. The locking arrangement 9 is in an unlocked state. FIGS. 6A, 6B shows the plan views of the front side V (FIG. 6A) and rear side S (FIG. 6B) of the locking arrangement 9, wherein it is in a locked state.

[0127] According to FIGS. 5A and 6B, the locking arrangement 9 extends, as described in FIG. 4, in the wall portion 44 and in the external door leaf 20a, wherein the door leaf 30a and the wall portion 44 are omitted from the drawing. The front side V is directed toward the interior of the compartment 3 and the rear side S is directed outside the compartment 3.

[0128] The locking arrangement 9 has the lock actuator 6. The lock actuator 6 comprises the first position sensor 25 which detects the absolute door position of the door 4. The lock actuator 6 transmits the door position as the first position signal 28 to the control device 7 of the control and information system 1.

[0129] The lock actuator 6 contains a housing 38, a first actuation element 27 in the form of a first bolt, a second actuation element 41 in the form of a second bolt and a first toothed wheel 42. The first actuation element 27 and the second actuation element 41 are directed in the same direction in the housing 38 (relative to the longitudinal axis or longitudinal extent direction of the bolts, directions R1, 2) and/or received parallel with each other, wherein both actuation elements 27, 41 extend substantially horizontally and/or levelly relative to the base 40. The first actuation element 27 and the second actuation element 41 are arranged or guided/supported for translational movement in the housing 38, wherein they can partially move out of the housing 38. Both actuation elements 27, 41 are actively connected by means of the first toothed wheel 42. To this end, both actuation elements 27, 41 have external toothings on the outer sides thereof which are directed toward each other and with which the first toothed wheel 42 can mesh.

[0130] The lock actuator 6 has a drive device 37 having an electric motor for generating a torque. The drive device 37 contains a spindle device 39, for example, a steep-threaded spindle, which converts the torque into a linear force and which transmits it to the first actuation element 27 in a non-self-locking manner. To this end, the spindle device 39 engages in the first actuation element 27 by being arranged in a hollow space of the first actuation element 27.

[0131] When the linear force is introduced into the first actuation element 27, it is moved in a first linear direction R1 toward the external door leaf 30a. As a result of the active connection via the first toothed wheel 42, the second actuation element 41 is simultaneously and synchronously moved in the opposite direction in a second opposite linear direction R2 away from the external door leaf 30a in the event of or during the movement of the first actuation element 27.

[0132] The locking arrangement 9 contains the locking apparatus 43. The locking apparatus 43 has an additional housing 50. It contains a blocking element 47 which is in the form of a blocking bar. The locking apparatus 43 further has a closure element 49 which is in the form of a closure bar.

[0133] The blocking element 47 and the closure element 49 are received in the additional housing 50 (relative to the longitudinal extent or movement directions B, G thereof) in the same direction and/or parallel with each other, wherein both elements 47, 49 extend substantially horizontally and/or levelly with respect to the base 40. The blocking element 47 and the closure element 49 are arranged for translational movement in the housing 50, wherein they can move partially out of the housing 50. Both elements 47, 49 are actively connected by means of a second toothed wheel 51. To this end, both elements 47, 49 have external toothings at the outer sides thereof which are directed toward each other and with which the second toothed wheel 51 can mesh.

[0134] The blocking element 47 can be moved from a movement position, which is shown in FIGS. 5A, 5B, into a blocking position which is shown in FIGS. 6A, 6B. In the blocking position according to FIGS. 6A, 6B, the blocking element 47 engages in the hinge device 31 and thereby blocks a door movement of the door 4, in particular an opening movement and a closing movement. In the movement position according to FIGS. 5A, 5B, the blocking element 47 is arranged outside the hinge device 31 in the external door leaf 30a so that it is possible to move the door.

[0135] In order to move the blocking element 47 into the blocking position, it can be moved in a blocking direction B. The blocking direction B corresponds to the first linear direction R1. By moving the blocking element 47 in an opposite direction to the blocking direction B, that is to say, the closing direction G, it can be moved into the movement position. The closing direction G corresponds to the second linear direction R2.

[0136] The closure element 49 can be moved from an unlocking position, which is shown in FIG. 5A, 5B and in which the door 4 is unlocked, into a locking position which is shown in FIGS. 6A, 6B and in which the door 4 is locked. In the locking position according to FIGS. 6A, 6B, the closure element 49 engages in the wall portion 44. In the unlocking position according to FIGS. 5A, 5B, the closure element 49 is arranged outside the wall portion 44 in the external door leaf 30a. In order to move the closure element 49 into the locking position, it can be moved in the closing direction G. By moving counter to the closing direction G (in the blocking direction B), the closure element 49 can be moved into the unlocking position.

[0137] As a result of the active connection via the second toothed wheel 51, the closure element 49 is simultaneously and/or synchronously moved in the opposite direction in the closing direction G in the event of and during the movement of the blocking element 47 in the blocking direction B, and vice versa.

[0138] The first actuation element 27 is aligned with the blocking element 47 so that an end, which is directed in the first linear direction R1, of the first actuation element 27 is arranged adjacent to/adjoining and not connected to an end, which is directed counter to the direction R1, of the blocking element 47. The two ends are arranged in the movement position of the blocking element 47 according to FIGS. 5A, 5B between the wall portion 44 and the external door leaf 30a. Consequently, it is possible to pivot the external door leaf 30a relative to the wall portion 44 in the movement position. In that the ends are not connected, the first actuation element 27 can transmit exclusively a pressing force in the direction R1 to the blocking element 47, that is to say, not a tension force counter to the direction R1.

[0139] The second actuation element 41 is aligned with the closure element 49 so that an end, which is directed counter to the direction R2, of the second actuation element 27 is arranged adjoining/adjacent to and not connected to an end, which is directed in the direction R2, of the closure element 49. The two ends are arranged in the unlocking position of the closure element 49 according to FIGS. 5A, 5B between the wall portion 44 and the external door leaf 30a. Consequently, it is possible to pivot the external door leaf 30a relative to the wall portion 44 in the movement position. In that the ends are not connected, the second actuation element 41 can transmit exclusively a pressing force to the closure element 49, that is to say, not a tension force.

[0140] The transition from the situation from FIGS. 5A, 5B (door unlocked) to the situation from FIGS. 6A, 6B (door locked) is carried out in this manner.

[0141] In the case of/during the transmission of the linear force by the spindle device 39, the first actuation element 27 is moved in the first linear direction R1. In this case, it displaces the blocking element 47 in the blocking direction B in a state not connected thereto and exclusively by applied pressure and moves it from the movement position into the blocking position. By means of the first toothed wheel 42, the second actuation element 41 is synchronously/simultaneously moved in the opposite direction to the first actuation element 27 in the second linear direction R2. By means of the second toothed wheel 51, the closure element 49 is synchronously/simultaneously moved in the opposite direction to the blocking element 47 in the closing direction G from the unlocking position into the locking position.

[0142] The transition from the situation from FIGS. 6A, 6B (door locked) to the situation from FIGS. 5A, 5B (door unlocked) is carried out in this manner.

[0143] If the rotation direction of the spindle device 39 is changed, the first actuation element 27 is moved back counter to the first linear direction R1. In this case, the second actuation element 41 is moved in the opposite direction counter to the second linear direction R2 by means of the first toothed wheel 42 so that the second actuation element 41 displaces the closure element 49 counter to the closing direction G from the locking position into the unlocking position. This is again carried out simply by pressing/abutment without any connection between the two components. By means of the second toothed wheel 51, the blocking element 47 is moved in the opposite direction counter to the blocking direction B and moved from the blocking position into the movement position.

[0144] In order to move the blocking element 47 into the blocking position and to move the closure element 49 into the locking position, a pushing force is transmitted from the first actuation element 27 to the blocking element 47. In order to move the closure element 49 into the unlocking position and to move the blocking element 47 into the movement position, a pushing force is transmitted by the second actuation element 41 to the closure element 49.

[0145] The lock actuator 6 contains the first and second position sensor 25, 26 and transmits the position of the first actuation element 27 as the first position signal 28 and the door position as the second position signal 29 to the control device 7 of the control and information system 1.

[0146] The locking apparatus 43 can be manually actuated in addition to the lock actuator 6. This is possible as a result of the non-self-locking force transmission of the drive device 37. For manual actuation, the locking apparatus 43 has a gripping element which is arranged in a concealed manner at the outer side or rear side S and at the front side V. It has the advantage that the door 4 can be unlocked and opened or closed and locked in the event of a defect of the lock actuator 6 or during a power failure. The gripping element is actively connected to the closure element 49 so that, in the case of actuation, for example, during a displacement of the gripping element, the closure element 49 can be moved in the closing direction G or in the blocking direction B and so that the blocking element 47 which is actively connected via the second toothed wheel 51 can be moved accordingly synchronously in the opposite direction.

[0147] The locking arrangement 9 contains an indication device 52. The indication device 52 has an indication element 53. The indication element 53 outputs at the outer side/rear side S and optionally additionally at the front side V through a recess in the external door leaf 30a an indication of whether the door 4 is locked and the compartment 3 is occupied or whether the door 4 is unlocked and the compartment 3 is free. The indication element 53 is coupled to the gripping element and/or the closure element 49 so that it is movable or displaceable together therewith and outputs the corresponding indication in accordance with the locking position or the unlocking position.
