    [0001] TECHNICAL FIELD The invention relates to a device for locking a door, in particular a toilet door, for example for a vehicle. railway, aeronautical, maritime or road, or for a building. Already known in the state of the art, a locking device of a door, comprising a movable latch between a locking position and an unlocking position, and means for actuating this lock, suitable for moving this lock enters its unlocking and locking positions. These actuating means are for example formed by a door button accessible from the inside of the cabin, so as to be actuated by a user wishing to lock himself. Such a locking device generally comprises other means for actuating this lock, also suitable for moving this lock between its locking and unlocking positions. These other actuating means are then intended to be accessible from outside the cabin, by means of an actuating element, for example a key of suitable shape. Such a locking device makes it possible to define different locking states of the cabin, in particular so-called "free", "occupied" and "condemned" states. The cabin is said to be in a free state when a user can freely access the interior of the cabin. In the case of the locking device mentioned above, the cabin is in the free state when the lock is in the unlocked position. The cabin is said to be in an occupied state when a user occupies it and is locked in it. In the case of the locking device mentioned above, the lock is then in the locked position, the user having moved in this locking position by actuating the door knob accessible from inside the cabin. Finally, the cabin is said to be condemned when access is forbidden, in particular by a member of a technical team. This is for example the case when the cabin, having been considered as non-functional, is locked deliberately and manually by a member of a technical team. In the case of the locking device mentioned above, the lock has been moved into the locking position by means of said other actuating means accessible from outside the cabin. It is important for users to be able to distinguish the busy state from the condemned state. Indeed, in the busy state, users know that another user is currently occupying the cabin, so this cabin should be released 3025822 2 shortly. On the other hand, in the condemned state, users know that the cabin will remain inaccessible. Usually, in particular in certain railway vehicles, it is desirable to list the cabins in a condemned state, in particular by transmitting a signal of conviction from a locked cabin to a central control unit. For this purpose, the cabin is usually equipped with an additional lock which, when activated, sends a locking signal to the central control unit, according to which the cabin is locked. It should be noted that such a lock does not act on any lock, but is only intended for the transmission of the locking signal. Thus, when a member of the technical team wishes to condemn the cabin, it must, on the one hand, actuate said other actuating means to move the lock in the locking position and, on the other hand, actuate the additional lock to transmit the judgment signal to the central control unit.
    [0002] In other words, this member of the technical team must operate two separate locks to cleanly pass the cabin in the condemned state. However, there is no guarantee that the two locks are actuated, which can lead to errors if you forget to operate one of these locks. For example, the lock may be in the unlocked position while the judgment signal is issued. In particular, it is important that a user locked in a cabin can leave at any time, especially when the cabin is in the condemned state. In the case of the locking device mentioned above, the user can exit the cabin by actuating the lock towards its unlocking position, even when the cabin is considered as locked, and that said additional lock has been activated to transmit the condemnation signal. In this case, after the user has left the cabin, this cabin is free to access, while it is considered condemned by the technical team. The object of the invention is in particular to remedy this disadvantage by providing a locking device making it possible to avoid errors in indicating a busy or condemned state of the door, particularly because of the presence of a user. in the cabin if the door is locked. For this purpose, the invention particularly relates to a locking device for a door intended to be mounted on a frame, said door having an inner face and an outer face, and said frame having an inner face and an outer face, the locking device comprising: - an outer door handle, intended to be arranged on the outer face of the door, and an inner door handle, intended to be arranged on the inner face of the door, and - a first bolt, intended to be carried by the door, movable between a projecting position and a retracted position, characterized in that it comprises: - first means for moving the first bolt between its protruding position and its retracted position, these first moving means being activatable only by the interior door handle among the inner and outer door handles, - a first waste removable, intended to be carried by the frame facing the first bolt, having a movable portion, movable tilting about a tilting axis, regardless of the position of the first bolt, - a latch, intended to be carried by the frame movable between a first position, in which the latch cooperates with the movable part to keep it immobilized so that it forms a stop for the first bolt in the projecting position, and a second position, in which the latch is maintained at the deviation of the moving part to allow its free tilting around the tilting axis, - mechanical means for actuating the latch, intended to be accessible from the outer face of the frame, suitable for moving the latch between its first and second positions. The locking device according to the invention is in the condemned state when the latch is in its first position. This latch is passed into this first position by means of said mechanical latch operating means, which are independent of any other user operable locking member, such as a door knob. When the latch is in its first position, the first striker forms a stop for the first bolt. However, this first bolt can be operated by means of the inner door handle, so that it is not possible to open the door from the outside. On the other hand, a user locked in the cabin can get out by operating the interior door handle, retracting the first bolt which can thus leave the first striker, then allowing the opening of the door. When the user exits the cabin, he releases the interior door handle, so that the first bolt returns to its retracted position. When the door is closed, for example by means of an automatic door closer, this first bolt is located in the first striker, so that the cabin remains inaccessible from the outside. The cabin remains in its condemned state, even if a user, who was locked inside, leaves.
    [0003] A locking device according to the invention may further comprise one or more of the following features, taken alone or in any technically feasible combination. The locking device comprises electronic means for controlling the first removable striker, switchable between a locking configuration, in which said movable part is immobilized, forming a stop for the first bolt in the protruding position, and a release configuration. wherein said movable portion is free to tilt about its tilt axis. The locking device comprises first means for detecting the position of the latch, and first means for transmitting a signal to a control unit, suitable for emitting a signal according to which the door is locked when the first means detection detects the latch in its first position. - The first detection means comprise a movable pusher between a high position and a low position, said pusher being arranged near the latch, so that the latch in its first position cooperates with the pusher by passing it in its lower position. - The actuating means of the latch comprises a form of engagement, intended to be accessible from the outer face of the door, and intended to cooperate with a complementary actuating element, including a key. - The locking device comprises a second bolt, intended to be carried by the door, movable between a projecting position and a retracted position, and second means for moving the second bolt between its projecting position and its retracted position, these second moving means being activatable by each door handle among the inner and outer door handles. The locking device comprises second means for detecting the position of the second bolt, and second means for transmitting a signal to a control unit when the second detection means detect the second bolt in its retracted position. - The locking device comprises a third bolt, intended to be carried by the door, movable between a projecting position and a retracted position, an actuating element 35, in particular a door knob, intended to be carried by the door on its inner face, and third means for moving the third bolt between its protruding position and its retracted position, these third moving means being activatable by the actuating element. The third means for moving the third bolt can be activated by the inner door handle for the passage of the third bolt from its protruding position towards its retracted position. The locking device comprises third means for detecting the position of the third bolt, and third means for transmitting a signal to a control unit when the third detection means detect the third bolt in its projecting position. The locking device comprises a control unit, and visual display means, such that: when the control unit receives a signal according to which the latch is in its first position, then the display means indicate that the door is locked, and when the control unit receives a signal that the third latch is in its projecting position, but does not receive a signal that the latch is in its first position, then the means display indicates that the door is locked by a user. The locking device comprises audio indication means, such as: when the control unit receives a signal according to which the second bolt is in its retracted position, and when the control unit receives a signal according to which the latch is in its first position, then the audio indication means emits an audio message that the door is locked, and when the control unit receives a signal that the second bolt is in its retracted position, and that the control unit receives a signal that the third latch is in its projecting position, but that it does not receive a signal that the latch is in its first position, then the audio indication means emits an audio message according to which door is locked by a user. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, in which: FIG. 1 is a view of an outer face of a door, equipped with a locking device according to an exemplary embodiment of the invention; - Figure 2 is a detail of a part of the locking device equipping the door of Figure 1, shown partially broken away and seen from the side of an inner face of the door.
    [0004] FIG. 1 shows a door 10, in particular a toilet cabin door for a railway vehicle.
    [0005] This door 10 is carried by a frame 12, in which is arranged a door frame 14 defining a passage opening. The door 10 is movable conventionally between an open position allowing access to the cabin through the passage opening, and a closed position prohibiting access to the cabin by closing the passage opening.
    [0006] The door 10 has an outer face 10A, shown in Figure 1, and an inner face 10B, partially visible in Figure 2. The door 10 is equipped with a locking device, designated by the general reference 16. The device lock 16 comprises an outer door handle 18, 10 arranged on the outer face 10A of the door 10, and an inner door handle 20, arranged on the inner face 10B of the door 10. These outer handles 18 and inner 20 allow to operate different door bolts that will be described later. The locking device 16 comprises a first bolt 22, carried by the door 15, movable between a projecting position and a retracted position. This first bolt 22 is for example of the type latch bolt. The first bolt 22 is moved between its projecting position and its retracted position by first moving means (not shown). These first moving means are connected only to the inner door handle 20 among the inner door handles 20 and outer 18. Thus, the first bolt 22 can pass into its retracted position by actuating the inner handle 20 The actuation of the outer handle 18 has no effect on the first bolt 22. The first displacement means further comprise an elastic element for returning the first bolt 22 to its projecting position, for example a spring.
    [0007] These first moving means are of conventional type, and will therefore not be described in more detail. The locking device 16 also comprises a first striker 24, of removable type, intended to be carried by the frame 12, in particular by the door frame 14. The first striker 24 comprises a movable part 26, movable in tilting around a tilting axis, independently of the position of the first bolt 22. The first striker 24 is arranged opposite the first bolt 22, so that the first bolt 22 is housed in the first striker 24 when it is in its position. projection. Advantageously, the locking device 16 comprises electronic means (not shown) for controlling the first removable keeper 24, switchable between a locking configuration, in which said movable portion 26 is immobilized, and a release configuration, in which the mobile part 26 is free to swing around its tilting axis. Such electronic control means are conventional and will not be described further. When the movable portion 26 is immobilized, it forms a stop for the first bolt 22 in projecting position, thus opposing the opening of the door. It is then necessary to pass the bolt 22 in its retracted position, by actuating the inner handle 20, to release it from the first striker 24, and thus allow the opening of the door. In this case, since the outer handle 18 does not operate the first bolt 22, it is impossible for a user to open the door from the outside. On the other hand, when the movable part 26 is free, it does not form an obstacle 10 for the first bolt 22 in projecting position when the door 10 is opened. The first bolt 22 and the first striker 24 are not visible. thus not opposing the opening of the door by a user from outside the cabin. These first electronic control means can be activated automatically. For this purpose, the locking device comprises means 15 for detecting an operating anomaly of the toilet cabin (for example linked to arrivals and discharges of water), so as to switch the control means to a locking configuration in case of detection of an anomaly. In other words, when an anomaly is detected, the washroom is automatically placed in condemned state.
    [0008] The locking device 16 according to the invention further comprises a latch 28, carried by the frame 12, movable between a first position (designated by the reference 28A in Figure 2), wherein the latch 28 cooperates with the movable part 26 to maintain it immobilized, so that it forms a stop for the first bolt 22 in projecting position, and a second position (designated by the reference 28B in FIG. 2), in which the latch is held in position. distance from the mobile part 26, to allow its free tilting around its tilting axis, so that it thus does not form an obstacle for the first bolt 22 in projecting position when the door 10 is opened. The latch 28 is for example rotatable about a pivot 29 between its first 28A and second 28B positions. Alternatively, the latch 28 could be movable in translation. The latch 28 is moved between its first 28A and second 28B positions by first mechanical actuating means 30, accessible from the outer face of the door 10. These first mechanical actuating means 30 are generally arranged on the frame 12, in view of the pivot 29 around which the latch 28 is movable in rotation.
    [0009] These first actuating means of the latch 30 comprise a form of engagement, accessible from outside the cabin, integral in rotation with the latch 28. This form of engagement is intended to cooperate with a complementary actuating element. (not shown), including a key. In other words, this form of engagement has a shape that can be rotated by this actuating member. The form of engagement forms for example a male part, and the actuating element then comprises a cylindrical portion provided with a complementary hole forming a female part. Thus, the actuating member makes it possible to manipulate the rotation of the latch 28 when engaged on the engagement form. For example, the form of engagement has a square section, but any other form allowing a drive in rotation of the engagement form by the actuating element is alternatively feasible. Thus, it appears that a member of a technical team, provided with the actuating element, can tilt the latch in its first position, thus passing the cabin into the condemned state. The locking device 16 also comprises first means 32 for detecting the position of the latch 28. These first detection means 32 comprise, for example, a switch, carried by the frame 12, comprising a pusher 34, movable between a high position and a low position. This pusher 34 is arranged near the latch 28, so that the latch 28 in its first position 28A cooperates with the pusher 34 by passing it in its lower position. The first detection means 32 are connected to first means of transmitting a signal to a control unit 36, able to send a signal relating to the position of the latch 28 detected by these first detection means 32. For example these first transmission means emit a signal according to which the door is locked when the first detection means 32 detect the latch 28 in its first position 28A, that is to say when the pusher 34 is in its low position.
    [0010] Advantageously, the first transmission means are also connected to said electronic control means, in order to send to the control unit 36 a signal according to which the gate 10 is in the condemned state when the electronic control means are in condemnation configuration. Preferably, the transmitted signal carries a different information in the case where the mobile part 26 of the striker 24 is immobilized automatically and in the case where this mobile part 26 is immobilized mechanically by the latch 28. Thus, the unit 3025822 9 control 36 can distinguish the case where the conviction is manual, through the latch 28, or when it is automatic, through the electronic control means. The locking device 16 further comprises a second bolt 37, carried by the door 10, movable between a projecting position and a retracted position. This second bolt 37 is for example of the type latch bolt. The second bolt 37 is moved between its projecting position and its retracted position by second displacement means (not shown). These second moving means are connected to the inner door handle 20 and to the outer door handle 18. Thus, the second latch 37 can move into its retracted position by actuating one or other of the inner handles 20 and 18. The second displacement means further comprise an elastic return element of the second bolt 37 to its projecting position, for example a spring. These second moving means are of conventional type, and will therefore not be described in more detail. The second bolt 37 cooperates with a second fixed keeper 38 of conventional type formed in the frame 12, in particular in the door frame 14. The second striker 38 is arranged facing the second bolt 37, so that the second latch 37 is housed in this second striker 38 when in its projecting position. Thus, the second bolt 37 abuts against one edge of the second striker 38 when it is in projecting position, preventing the opening of the door 10. On the other hand, when the second bolt 37 is in its retracted position, it leaves the second striker 38, and therefore does not oppose the opening of the door 10. The locking device 16 comprises second means 40 for detecting the position of the second bolt 37. These second detection means 40, of conventional type, are connected to second means for transmitting a signal, relative to the position of the second bolt 37, to the control unit 36. More particularly, the second transmission means emit a signal when the second detection means 40 detect the second bolt 37 in its retracted position.
    [0011] The locking device 16 finally comprises a third bolt 42, of dead bolt type, carried by the door 10, also movable between a projecting position and a retracted position in the door 10. The third bolt 42 is moved between its position in position. protrusion and its position retracted by third moving means (not shown). These third moving means are connected to an actuating element 44, for example a door knob, carried by the door 10 on its inner face 10B.
    [0012] Advantageously, the third moving means are also connected to the inner door handle 20 for the passage of the third bolt 42 from its projecting position to its retracted position. Thus, the actuation of the inner handle 20 makes it possible to pass each of the first 22, second 37 and third 42 bolts in their respective retracted position, and thus allows the door 10 to be opened from the inside of the cabin in all case. The third moving means are of conventional type, and will not be described in more detail. The locking device 16 comprises a third fixed striker 46 of the conventional type designed to cooperate with the third latch 42. The third striker 46 is arranged opposite the third latch 42, so that this third latch 42 is housed in this third latch. keeper 46 when in its projecting position. Thus, the third bolt 42 abuts against an edge of the third striker 46 when it is in projecting position, preventing the opening of the door 10. On the other hand, when the third bolt 42 is in its retracted position, it leaves the third striker 46, and therefore does not oppose the opening of the door 10. In addition, the locking device 16 comprises third means 48 for detecting the position of the third bolt 42, connected to third means for transmitting a signal, relating to the detected position of the third bolt 42, to the control unit 36. More particularly, a signal is emitted when the third detection means 48 detect the third bolt 42 in its projecting position. It should be noted that the latch 28, the electronic control means, the different strikes and the different detection means are usually hidden from inside the cabin by a panel (not shown in Figure 2).
    [0013] Advantageously, the locking device 16 comprises second mechanical means 54 for actuating the inner door handle 20 from outside the cabin. These second actuating means 54 comprise a form of engagement connected to the same bolt moving means as the inner handle 20, for example rotatably connected to the inner handle 20. This form of engagement is intended to cooperate with a complementary actuating element, forming a key, and thus has a shape capable of being rotated by such an actuating element. This actuating element is generally the same as that used to activate the first mechanical means for actuating the latch 30. These second actuating means 54 allow a member of the technical team to access the cabin, which it is in its occupied state or condemned, for example to assist a user locked in this cabin.
    [0014] The locking device 16 comprises visual display means 50 intended to display a visual indication relating to the free, occupied or condemned state of the cabin. Indeed, it is important for the users to know the state of the cabin, in particular in order to know if it is accessible (free state), whether it will be released 5 soon (busy state), or if it will remain inaccessible (condemned state ). The control unit 36 is able to determine the state of the cabin, depending on the positions of the latch 28 and the third latch 42, as will be described later. Furthermore, the locking device 16 advantageously comprises means 52 audio indication, may indicate by an audio message what is the state 10 of the cabin. For example, an audio message is delivered when the second detecting means detects that the second latch 37 is in its retracted position, which means that a door handle 18, 20 is actuated. These audio messages allow a visually impaired user to know the status of the booth. The operation of the locking device 16 will be described below.
    [0015] The cab is in the free state when: - the latch 28 is in its second position 28B, - the electronic control means are in their release configuration, - the second bolt 37 is in its projecting position, and - the third bolt 42 is in its retracted position.
    [0016] The first bolt 22 is also in its projecting position, but it does not hinder the opening of the door 10 since the movable portion 26 of the first striker 24 is not immobilized by the latch 28 or by electronic means. control. In the absence of receiving a signal that the latch 28 is in its first position 28A (or, alternatively, in the presence of receiving a signal that the latch is in its second position 28B) and in which lack of reception of a signal according to which the electronic control means are in their locking configuration (or alternatively in the presence of a signal according to which the electronic control means are in their release configuration), the control 36 infers that the cabin is not in a condemned state.
    [0017] Then, in the absence of receiving a signal according to which the third bolt 42 is in its projecting position (or, alternatively, in the presence of a signal according to which the third bolt 42 is in its retracted position), the control unit 36 deduces that the cabin is in the free state. The display means 50 thus display that the cabin is in its free state.
    [0018] When the outer handle 18 is actuated, the control unit 36 receives a signal that the second latch 37 is in its retracted position, and the audio indication means 52 then emits an audio message that the booth is in free state. As a variant, in the free state, the audio indication means 52 emit no audio message, since a simple activation of the external handle 18 makes it possible to know that the door can open, which corresponds in all cases. cases in a free state. Once the user inside the cabin, it closes the door, so that the second bolt 37 returns to its projecting position, and it actuates the actuating element 44 to lock the door. The cab is in the occupied state when: the latch 28 is in its second position 28B, the electronic control means are in their release configuration, the second bolt 37 is in its projecting position, and the third bolt 42 is in its projecting position. The first bolt 22 is also in its projecting position, but it does not hinder the opening of the door 10 since the movable portion 26 of the first striker 24 is not immobilized by the latch 28 or the electronic means of control. As before, the control unit 36 deduces that the cabin is not in a condemned state. Then, upon receiving a signal that the third latch 42 is in its projecting position (or, alternatively, in the absence of a signal that the third latch 42 is in its retracted position), control unit 36 deduces that the cabin is in the busy state. The display means 50 thus display that the cabin is in its busy state. If the outer handle 18 is actuated, the control unit 36 receives a signal 25 in which the second latch 37 is in its retracted position, and the audio indication means 52 then issue an audio message that the car is in the same position. busy state. Alternatively, the audio indication means 52 emit no message if it is the inner handle 20 is actuated. The control unit 36 deduces that it is the inner handle 20 is actuated when the second bolt 37 and the third bolt 42 both pass into their retracted position, while the third bolt 42 was in its projecting position. In the event of an anomaly detected, the automatic control means immobilize the moving part 26 of the first striker 24. In this case: the latch 28 is in its second position 28B, 3025822 13 - the electronic control means are in their locking configuration, - the second bolt 37 is in its projecting position, and - the third bolt 42 is in its protruding position if a user is locked in the cabin, and in the retracted position in the opposite case. The first bolt 22 is in its projecting position, cooperating with the first striker 24 whose movable portion 26 is immobilized, thus preventing the door 10 from being opened from the outside by a user, since the external handle 18 does not allow act on this first bolt 22.
    [0019] On receipt of a signal according to which the electronic control means are in their locking configuration (or alternatively in the absence of a signal according to which the electronic control means are in their release configuration), the control 36 deduces that the cabin is in condemned state, and this whatever the position of the third bolt 42.
    [0020] The display means 50 thus display that the cabin is in its condemned state. If the outer handle 18 is actuated, the control unit 36 receives a signal that the second latch 37 is in its retracted position, and the audio indication means 52 then emits an audio message that the car is in a state of readiness. condemned. Alternatively, the audio indication means 52 emit no message if it is the inner handle 20 is actuated. The control unit 36 deduces that it is the inner handle 20 that is actuated when the second latch 37 and the third latch 42 are both in their retracted position, while the third latch 42 is in its protruding position. If a user was in the cabin during his conviction, he can get out by operating the inner handle 20, which acts on each of the first 22, second 37 and third 42 bolts, all of which pass into their retracted position, out of their latch respective, thereby allowing the door to open.
    [0021] This actuation of the inner handle 20 has no effect on the automatic control means, so that the cab remains in the locked state. When the door closes, the first bolt 22 returns to its projecting position in the first striker 24, so that the door 10 can still not be opened from the outside by a user.
    [0022] A member of the technical team may however open the door with the second actuating means 54, which have the same effect as the actuation of the inner handle 20, as described above. The cabin can also be passed into the condemned state by a member of the technical team, who actuates for this purpose the first actuating means 30. In this case, the latch 28 comes to immobilize the moving part 26 of the first keeper 24, so that: - the latch 28 is in its first position 28A, - the electronic control means are in their release configuration 10 (or condemnation), - the second bolt 37 is in its projecting position, and the third bolt 42 is in its protruding position if a user is locked in the cabin, and in the retracted position in the opposite case. The first bolt 22 is in its projecting position, cooperating with the first striker 24, the movable portion 26 of which is immobilized, thus preventing the door 10 from opening from the outside by a user, since the external handle 18 does not allow not acting on this first bolt 22. Upon receipt of a signal that the latch is in its first position 28A (or alternatively in the absence of signal that the latch is in its second position 28B), the control unit 36 deduces that the cabin is in condemned state, and this regardless of the position of the third latch 42. The display means 50 thus display that the cabin is in its condemned state. If the outer handle 18 is actuated, the control unit 36 receives a signal 25 in which the second latch 37 is in its retracted position, and the audio indication means 52 then emit an audio message according to which the cab is in state condemned. Alternatively, the audio indication means 52 emit no message if it is the inner handle 20 is actuated. The control unit 36 deduces that it is the inner handle 20 is actuated when the second bolt 37 and the third bolt 42 both pass into their retracted position, while the third bolt 42 was in its projecting position. If a user was in the cabin during his conviction, he can get out by operating the inner handle 20, which acts on each of the first 22, second 37 and third 42 bolts, all of which pass into their retracted position, leaving their respective latch, thus allowing the opening of the door.
    [0023] This actuation of the inner handle 20 has no effect on the position of the latch 28, so that the cab remains in the locked state. When the door closes, the first bolt 22 returns to its projecting position in the first striker 24, so that the door 10 can still not be opened from the outside by a user.
    [0024] A member of the technical team, on the other hand, can open the door by means of the actuating means 54, which have the same effect as the actuation of the inner handle 20, as described above. Note that the invention is not limited to the embodiment described above, but could have various variants.
    [0025] For example, the automatic control means could alternatively act on the position of the latch 28. According to another variant, the position of the latch 28 could act on the configuration of the automatic control means. 15
