    [0001] The present invention relates to an access device enabling controlled or even secure communication between different areas of an enclosure and for example an aircraft. More particularly, the device allows in particular to protect the cockpit access from the cabin. The present invention also relates to the aircraft equipped with such an access device. TECHNICAL FIELD In current aircraft, the cockpit is separated from the cabin by a shielded partition wall with an access door. The door can be locked from inside the cockpit to avoid any aggression from the cabin. The cabin may have different types of arrangement near the cockpit: - A toilet adjacent to the partition wall between the cabin and the cockpit and positioned on one side of the door of said partition; - toilets and kitchens attached to the partition wall between the cabin and the cockpit and positioned on either side of the door of said partition in a direction transverse to the aircraft; - Passenger seats placed as close as possible to the bulkhead between the cabin and the cockpit. Very few aircraft have toilets assigned only to pilots. The latter must leave the cockpit to use the toilets intended for passengers. Pilots may also wish to access the cabin for example to check the status of an aircraft system. The crew of an airplane may also need access to the cockpit for example to bring a meal to the pilots. But the use of the access door exposes pilots to aggression from the cabin.
    [0002] There is a configuration offering toilets and kitchens adjoining the cockpit and arranged on both sides of the cockpit access door. In this case, the toilets and the kitchens form a protection corridor at the access of the cockpit. However in other configurations, it is necessary to provide an additional protection system such as an airlock.
    [0003] PRIOR ART It is known from patent FR2965793 filed on October 8, 2010 to protect access to the cockpit by an airlock formed of movable walls capable of moving independently of one another so as to provide a single opening between them. allowing access to the cockpit or cabin. This device has the disadvantage of occupying a large cabin volume, particularly in configurations in which the seats are close to the partition separating the cockpit from the cabin. However, it is necessary for passenger comfort to have a minimum access perimeter to the airlock thus taking up space in 15 cabins for passenger seats. SUMMARY OF THE INVENTION To this end, the present invention proposes an access device 20 allowing secure communication between at least two zones of an enclosure, characterized in that it comprises at least three movable walls capable of moving, independently of each other, to form a closed cylinder, the walls then being in a position called SAS position and overlapping at least two to close access to one or more areas while removing the airlock, the walls then being in a position called retracted position. The SAS-shaped access device being retractable by superimposing its walls at the openings whose access must be managed, it avoids cluttering the space of the cabin adjoining said openings.
    [0004] The invention has at least one of the following optional features, taken alone or in combination. Each wall is made in one piece in one piece.
    [0005] Each wall has a perforated circular cylindrical shape and the walls are positioned concentrically about a common axis. The device comprises four perforated cylindrical walls forming a shutter, concentric circular section walls around a common axis such that in the SAS position, the shutters together form a closed circular cylinder and in another retracted position, they are superimposed on the less by two.
    [0006] Each wall is connected to means for holding and moving in rotation independently of those provided for each other wall. Each wall has two cylindrical rings to stiffen its structure and to ensure the link with the holding and moving means. The means for holding and moving each of the walls are such that they do not protrude from a floor.
    [0007] The present invention also relates to an aircraft comprising at least one access device having the above feature or characteristics. The aircraft comprises at least two zones provided with access openings that can be closed by the walls of the access device.
    [0008] 3036097 4 One of these areas is the cockpit, another of these areas is the cabin; the walls are superimposed to form a closure flap in the cockpit and completely release the cabin.
    [0009] Another of these areas are the toilets; the walls are likely to form a closure of the toilet access and simultaneously closing the access to the cockpit while completely freeing the cabin. BRIEF DESCRIPTION OF THE DRAWINGS Other objects, advantages and features of the invention will become apparent on reading the following description of the device according to the invention, given by way of non-limiting example with reference to the drawings appended hereto. which: - Figure 1 is a schematic plan view of a front portion 15 of an aircraft not provided with the access device according to the present invention; FIG. 2 is a perspective view of an embodiment of the access device according to the present invention; FIG. 3 is a perspective view of the access device in the form illustrated in FIG. 2 in several positions of use; FIG. 4 is a view making it possible to schematically illustrate the guide tracks of the access device according to the embodiment of FIGS. 2 and 3 represented in perspective; Figure 5 is an exploded perspective view of the various parts included in an access device according to the embodiment of Figures 2 to 4; FIGS. 6a to 6d are diagrammatic views from above of use positions of an embodiment of the access device illustrated in FIGS. 2 to 5 integrated with an aircraft.
    [0010] SUMMARY OF THE INVENTION As shown in FIGS. 1 to 6, the access device 1 is presented in the following description in the illustrative and nonlimiting context of access to a cockpit 2 in an aircraft. 4. The access device may be used in any other application requiring secure access to a plurality of adjacent areas of an enclosure and completely releasing the space taken by the access device in certain areas when no access is available. these are not required or only unsecured access. In general, and as shown in FIG. 1, the cockpit 2 is separated from a cabin 6 by a partition 8. The partition 8 has an opening 10 allowing a passage between the cockpit and the cabin for the pilots, the hostesses, 15 crew or other personnel. The cabin 6 comprises an area provided with rows 12 of seats 14 arranged transversely with respect to the longitudinal axis XX of the aircraft 4, toilets 16, kitchens, rest areas, storage areas or any other type of vehicle. zones according to various and varied arrangements. The purpose of the access device 1 is to be integrated with the aircraft so as to perform the above-mentioned function between areas of the cabin and the cockpit constituting itself a zone. In the embodiment illustrated in FIG. 1 and representing a particular cabin configuration, the cabin 6 comprises a toilet 16 25 adjoining the partition 8 and provided with an opening 18 providing a passage between the toilets 16 and the cabin 6. Rows 12 of seats follow one another up to the partition 8 and 16 to the toilet 16. A central circulation corridor 20 separate the rows 12A of seats located transversally to the side of the toilet 16 and the rows 12B of seats located from the floor. 'other side. Only 30 seats occupied by a passenger are represented by certain seats of the rows 12A 'and 12B' closest to the toilets 16 and the partition 8, respectively, in order to clearly indicate the space to be provided for the legs of the passengers. The access device 1 is integrated with the configuration illustrated to manage the access between the different zones of said illustrated configuration, namely a first zone constituted by the cockpit 2, a second zone constituted by the toilets 16 and a third zone constituted by the by the passenger area of the cabin in which are aligned the rows 12 of seats 14. The required accesses are shown in Figure 1 by double arrows: access to the cockpit 2, access to the toilet 16, access to the cabin 6 and more precisely to a longitudinal and transverse corridor 22 of the cabin 6.
    [0011] Figure 1 shows the bulk of a conventional airlock that would require removing the nearest 12 passenger seats from it. The access device 1 is located on the central longitudinal axis XX in the extension of the central corridor 20 and on a transverse axis passing through the toilet 16 and the transversal corridor 22 situated between the partition 8 and the row 12'B of seats. It is thus positioned more generally at the intersection of adjacent areas for which access management is desired while preserving the free space when this management is not required.
    [0012] The access device 5 comprises at least three movable walls 24A, 24B, 24C capable of moving independently of one another along closed and concentric paths. At least a part of one or more walls 24 makes it possible to seal the openings 10 and / or 18: this part is called flap in the following description. The geometry of the flaps of the walls 24 is determined so that contiguously they form a closed cylindrical surface (surface 26 in FIG. 3). The closed volume delimited by said closed cylindrical surface, the floor 28 and the ceiling (not shown) of the cabin 6 of the aircraft form the interior volume of said access device 1.
    [0013] Each of the walls 24 is movable along guide tracks 30 provided at the floor and the ceiling of the car and shown in FIG. 4. Tracks 30 may for example be in the form of grooves. inside which the walls 24 are introduced and move. The grooves 30 provided for each of the walls are concentric. According to the illustrated embodiment, the cylindrical surface 28 has a circular section; the grooves 30 then have a circular shape. In the latter case, the walls move around a same vertical axis located in the center of the circular grooves. The flaps of the walls 24 are of such shape and dimensions that they can be arranged with respect to each other so as to form a closed cylinder and in the form illustrated in FIG. 3 a cylinder 26 of circular section. According to a particular embodiment such as that illustrated, the walls 24 have a substantially identical shape and dimensions (they are slightly different from being positioned on separate guide tracks 15). In this way, when the walls are moved along the corresponding groove 30 to be placed one behind the other, they are superimposed thus leaving the occupied space previously free. That there are three, four walls 24 or more, they are movable independently of one another. The flaps of the walls 24 are likely to be positioned adjacent to form a closed cylinder 26 used in a position called SAS 32 position and to overlap at least two to close access to one or two zones while The size of the walls 24 and in particular the flaps and consequently the size of the guide tracks 30 is a function of the width of the openings allowing the passage between the different zones. which one wishes to manage the access control. Indeed, at least one of the flaps of the walls 24 must be adapted to the width of the opening that is intended to mask. For example, in the case of access management of two passages, at least two of the flaps have widths adapted to the width of the opening that each of them is intended to close.
    [0014] 3036097 8 When the access device 1 is in SAS position, it is necessary that two adjoining shutters are adjacent to each other, namely being located on neighboring concentric guide tracks. Thus, no space is released between the flaps from being on different guide tracks except between one of the edges of the flap of the outer wall (at the outermost guide track). ) and one of the edges of the flap of the inner wall (at the level of the innermost guide track). There is then provided a wall 36 for closing the space freed by positioning on non-neighboring guide tracks (the outermost and the innermost guide track). The wall 36 is more clearly visible in Figure 6d. The wall 36 has a parallelepipedal shape and in the illustrated rectangular example. It is positioned so that in the closed position of SAS, one edge adjoins the flap of the inner wall and the other of its edges adjacent the flap of the outer wall.
    [0015] In the case where the closed cylindrical surface 28 is of circular section, each of the walls 24 is rotatable about a central longitudinal axis of said cylindrical surface 28. The closing wall 36 is then positioned in a radial direction.
    [0016] According to the embodiment illustrated in Figures 2 to 5, each wall 24 is in the form of a perforated cylinder 38, the cylinder 38 being visible in its entirety in Figure 5. The cylinder 38 is perforated so as to forming two lower integral crowns 40 and upper 42 and a flap 44. Each of the rings 40 and 42 has a cylindrical shape of circular section. Each flap 44 has a curved parallelepipedal shape. The walls 24 are four in number 24A, 24B, 24C and 24D. The crowns 40 and 42 are placed in the grooves 30 above the ceiling and below the level of the floor so that the upper edge of the lower crown 40 is flush with the floor surface and so that the lower edge of the floor the upper crown 42 is flush with the ceiling surface. The floor and ceiling of the cabin are adapted to allow it. In this way, the crowns 3036097 9 and 42 are not visible in the cabin. Only the flap 44 appears. Each of the flaps 44A, 44B, 44C and 44D extends over an angular sector of 90 ° (or slightly more than a few degrees, which is made possible because each flap is on a guide track distinctly from that of the other 5 panels) so as on the one hand to completely close the internal volume at position 32 of SAS when each of the longitudinal ends of the flaps 44 abut the longitudinal end of another flap 44 (or the wall 36 closing) and on the other hand to leave free the space occupied by the flaps 44 in SAS position in the cabin, by superposing at least in two said flaps 44 at the openings 10 and / or 18 provided. Each groove 30 comprises systems for moving the walls 24 of known type. According to an exemplary system, the rings 40 and 42 can be displaced by means of lift, guide and / or safety rollers within the grooves 30. The lift rollers provided at the level of the floor support the wall to which they are associated and ensure its mobility along the groove. The guide rollers at the ceiling have the same functions as the lift rollers with the exception of support since they are positioned at the crowns 42 upper. The safety rollers 20 operate in case of negative accelerations. Locking devices and displacement control of known type are also provided. The locking systems can lock the walls relative to their fixed environment or relative to the other walls. It is also possible to add devices for the removal of particles of dust, fibers, various debris or other types likely to interfere with the operation of the installed systems. Such devices are also of known type and will not be described in more detail. They may be for example in the form of bristles, brushes, brushes or equivalents disposed on either side of the lift and guide rollers or suction systems.
    [0017] The walls 24 are made of a material that offers a good compromise between rigidity and lightness. They are for example made of composite sandwich materials, and more particularly based on carbon / Nomex (registered trademark), the carbon structure being made by overlapping plies 5 thin carbon fibers (for example 0.13 millimeters) (carbon of conventional thickness between 25 and 30 millimeters) structure within which is provided a central core of Nomex. All or only some parts of the access device may be shielded. The shielding is achieved for example by adding a coating of thin sheet steel bulletproof. Any other embodiment different from that presented above is possible.
    [0018] Thus, for example, the access device may comprise three movable flaps of angular sector 120 ° or slightly more than a few degrees, or a larger number of flaps of smaller angular sector.
    [0019] In another example, the walls 24 may be in a curved parallelepipedal shape. The illustrated embodiment in which a wall is constituted by a perforated integral cylinder improves the rigidity of the wall and facilitates mobility: increased rigidity avoids any bending may cause a blockage of the device. The crowns have closed geometries which make mobility easy to rotate. Rigidity plays an important role in the dynamic aspect namely mobility, rotation ... but also in the safety aspect which is the primary function of the access device. The access device must protect the passage of an individual from one area to another against any external aggression.
    [0020] The access device can be operated manually or automatically. In the case of a manual control, it is a person in the cabin who must ensure the unlocking / locking of the flaps for the deployment of the SAS. Thus, if a person from the cockpit wants secure access, he must contact a person in the cabin securely by radio or other means to ask him to set up the SAS. Additional visual means such as cameras can be used to visualize the area in question to ensure the establishment of the SAS. In the case of an automatic control, the triggering of the installation of the SAS can be carried out from the cabin and / or from the cockpit. Again, the system can include for people in the cockpit means for viewing the area in question. Figures 6a to 6d show four states of the access device 15 when used in the environment described in more detail below. As shown in FIGS. 6a to 6d, the aircraft equipped with the access device 1 is a single-aisle aircraft. The central circulation corridor 20 is located on the same central longitudinal axis as the opening 10 allowing passage between the cockpit 2 and the cabin 6. A toilet 16 is positioned against the partition 8 and on the same side of the corridor 20 , and in this case, the left side of the longitudinal axis XX facing the cockpit 2 inside the cabin 6. The toilet 16 is provided with an opening 18 allowing access between the toilet 16 and the cabin 2. One of the rows 12'A passenger seats is 25 near the toilet 16 and one of the rows 12'B near the partition 8. The access device is positioned to control the passages at 10 cockpit openings and 18 toilets. It is therefore at the intersection of the passages provided between the cockpit 2, the toilet 16 and the cabin 30 6. The size of the flaps 44 is determined in such a way that the flap (s) intended (s) to block the passage between the cabin and the cockpit and / or between the cabin 3036097 12 and the toilet closes the opening 10 and / or 18. The flap 44 being curved, its edges protrude relative to the flat surface of the partitions at which are the openings 10 and 18.
    [0021] In conditions of unsecured use, the access device 1 is retracted. The SAS used only in case of secure access is not visible and the space in front of the openings 16 of the toilet and 10 of the cockpit is clear. The access to the toilet and cockpit is therefore achieved in a conventional manner in addition to the fact that the doors are movable along guide tracks.
    [0022] FIG. 6a shows the use of access device 1 for unsecured control of the passage between cockpit 2 and cabin 6, for example for a pilot or a hostess. One of the flaps 44 is in the innermost illustrated form, hereinafter referred to as the closure flap 44f, moves to conceal or release the opening 10. The set of the other three flaps are positioned at from the opening 18 of the toilet. In this way, the toilets are closed so as not to be visible to the passengers sitting on the row 12'B seats. In addition, none of the flaps is located in the cabin 6 and more particularly in the space near the two openings 20 and 18. The passengers at the end of the rows 12'A and 12'B thus do not suffer from no discomfort. The flap 44f can move in two different directions to release the opening 18. According to the direction, the flap is locked in two different positions 46 and 48. In the position 46, the flap 44f is superimposed with the other three flaps 44 at the same level. from the opening 18 of the toilet. In this configuration, the passage between the cockpit 2 and the cabin 6 is released without taking on the space of the cabin. In position 48, the flap 44f faces the opening 18 and is in the illustrated embodiment in a position diametrically opposed to that of the other three flaps; it then protects the access to the cockpit of the passenger at the end of range 12'B. Once the passage 30 is no longer desired, the flap 44f returns to the closed position of the cockpit.
    [0023] Figure 6b shows the use of the access device 1 to unsecured control the passage between the cabin 6 and the toilet 16. The flap 44f is positioned to block the passage between the cabin 6 and the cockpit 2. In order to provide access to the toilets for the persons (passengers, pilot, hostess, etc.) the applicant 5, the three remaining shutters 44 are moved to be locked in a position facing the opening 10, and in the form illustrated embodiment, diametrically opposed to that held by the flap 44f. The access is then released and the three flaps make it possible to temporarily hide the person requesting access to the toilet from the rest of the cabin 6 since the three flaps are positioned at the central corridor. Once the person in the toilet, the three flaps return to the closed position of the toilet and the cabin space is cleared. To exit the toilet 16, the same operations are renewed.
    [0024] Figure 6c shows the use of the access device 1 in a secure manner to allow the pilot or any other person in the cockpit access to the toilet 16 while being protected from possible aggression of a person in the cabin. As shown in FIG. 6c, the flaps 44 are deployed to move to position 32 of SAS and form a closed cylinder 26 by means of the wall 36. The flap 44f is then moved to be locked in a facing position. at the opening 18 of the toilet and in the illustrated embodiment in a position diametrically opposed to that held by the shutter masking the opening 18 of the toilet. The pilot can then enter the SAS formed by the cylinder 26 whose access is released by moving the flap 44f. The flap 44f then returns to the closed position of the cockpit to avoid any intrusion into the cockpit of a person hiding in the toilet for example. The shutter blocking the opening 18 is then moved to be superimposed on the adjacent shutter facing the opening 10 (and in the illustrated embodiment diametrically opposite the shutter 44f closing the opening 10). The pilot can then access the toilets. The flap in question returns to the closing position of the toilet. Two options are then possible: the SAS remains in position or it retracts and redeploys when the pilot wishes to return to the cockpit. To return to the cockpit, the operations take place in the opposite direction. The present invention therefore provides a completely secure solution for access between the cockpit and the toilet while avoiding a bulky system in the cabin.
    [0025] Figure 6d shows the use of the access device 1 securely to allow the pilot or any other person in the cockpit access to the cabin or a hostess or any other person in the cabin to access the cockpit 2, while being protected from possible aggression of a person in the cabin. As shown in FIG. 6d, in the case where a person in the cockpit wishes to access the cabin or in the case where a person in the cabin wishes to access the cockpit in a secure manner, the flaps 44 unfold to move to position 32 of the cabin. SAS and form a closed cylinder 26. In the case where it is a person in the cabin, it is placed near the openings 10 and 18 so that the flaps 44 unfold around it and surround it completely. The flap 44f is then moved to be locked in a position facing the opening 18 and in the illustrated embodiment diametrically opposed to the position held by the shutter masking the opening 18 of the toilet. The person in the cockpit can then enter the SAS formed by the cylinder 26 or the person in the SAS out to get into the cockpit. The flap 44f then returns to the closed position of the cockpit to avoid any intrusion during the next step. In the illustrated embodiment, the shutter facing the opening 18 moves to release the passage to the booth. The flaps then resume their original positions or any other position depending on the desired operation. The present invention thus provides a completely secure solution for access between the cockpit and the cabin while avoiding a bulky system in the cabin.
