The actuating system 30 comprises for example a jack 44 mounted on the outer automatic locking plate 28 for actuating the latter in rotation relative to the frame about the axis D. One or more of the inner locking plate 12 the outer locking plate 16, the outer manual locking plate 22, the inner manual locking plate 26, the outer automatic locking plate 28 and the inner automatic locking plate 32 respectively form an advantageously partial disk, in which a sector angular about the axis D is at least partially withdrawn, or perforated, as shown in Figures 3 and 4.

The electric strike 34 is movable between a locked configuration adapted to automatically block the door 5, for example by holding a latch bolt of the door 5 (not shown), and a removable configuration adapted to allow the door to open, even if a latch bolt of the door is engaged in the electric strike.

The operation of the system 1 will now be described.

When the space 7 is free for use by a user (not shown), the door 5 is unlocked. The locking button 14 is then, in the example shown, in a vertical position deduced from that shown in Figure 2 by a rotation of a quarter turn upwards about the axis D. The locking plate inner 12 and the outer locking plate 16 are then in their open positions. The deadbolt 18 is in its retracted position, which is deduced from that shown in the figures by a translation of the deadbolt towards the interior of the frame 10. The first sign S1 and the third sign S3 are respectively aligned with the inner bezel 38 and the outer bezel 36.

The outer manual locking plate 22 is in its neutral position, in which the first window F1 is aligned with the outer bezel 36. Similarly, the outer automatic locking plate 28 is in its neutral position in which the third window F3 is aligned. with the outer bezel 36. Thus, the third sign S3 representative of the "free" state of the door 5 is visible from the outer side B through the first window F1, the third window F3 and the outer bezel 36.

Similarly, the inner manual locking plate 26 is in its neutral position, so that the second window F2 is aligned with the inner bezel 38. The outer automatic locking plate 32 is also in its neutral position, so that the fourth window F4 is aligned with the inner bezel 38. Thus, the first sign S1 also representative of the "free" state of the door 5 is visible from the inside through the second window F2, the fourth window F4 and the inner bezel 38. The user can then open the door 5 and enter the space 7. The user closes the door 5 and locks it with the locking button 14 by placing it in the position shown in FIG. This displacement of the locking button 14 causes the block formed by the inner locking plate 12 and the outer locking plate 16 to rotate about the axis D v to the respective closed positions of these plates. Through the connecting system 20, this actuates the deadbolt 18 from its retracted position to its extended position, and locks the door 5.

The second sign S2 and the fourth sign S4 are then aligned respectively with the inner bezel 38 and the outer bezel 36 and are respectively visible from the inner side A and the outer side B.

To exit, the user unlocks the door 5 by actuating the lock button 14 to return the inner locking plate 12 and the outer locking plate 16 to their open positions. This returns the deadbolt 18 to its retracted position and the door 5 can be opened.

To put the space 7 in the state "out of manual service", an operator (not shown), belonging in principle to the on-board staff of the railway vehicle, acts on the lock 24 using a key (not shown). The action on the lock 24 moves the outer manual locking plate 22 from its neutral position to its closed position (shown in FIG. 3). The first window F1 and the second window F2 are then no longer aligned with the outer bezel 36 and the inner bezel 38. The fifth sign S5 and the sixth sign S6, however, are aligned with the glasses. The fifth sign S5 is visible by the outer bezel 36 and the sixth sign S6 is visible by the inner bezel 38.

The outer manual locking plate 22 drives the inner manual locking plate 26 in rotation about the axis D. Similarly, the outer manual locking plate 22 drives, thanks to the stop 42 (FIG. 4), the locking plate 16 and the inner locking plate 12 rotated about the axis D to bring them into their respective closed positions. This, through the connecting system 20, moves the deadbolt 18 back to its extended position, which locks the door 5.

Regardless of the "free" or "busy" state, "manually condemned" or not of the door 5, the latter can be locked automatically thanks to the electric strike 34. To do this, the electric strike 34 passes from its detachable configuration. to its locked configuration.

In order to display the "automatic off" state of the space 7, the actuating system 30 actuates the outer automatic locking plate 28 in rotation about the axis D, from its neutral position to its automatic off position. The third window F3 is then no longer aligned with the outer bezel 36. In contrast, the seventh sign S7 is aligned with the outer bezel 36 and visible through it.

The inner automatic locking plate 32, being mechanically secured to the outer automatic locking plate 28, also moves from its neutral position to its automatic off position. The fourth window F4 is no longer aligned with the inner bezel 38, but the eighth sign S8 is. Thus, from the inner side A, it is the eighth sign S8 which is visible through the inner bezel 38.

Thanks to the elements described above, the system 1 is of a reduced cost, even in the presence of the optional elements which are the inner manual locking plate 26, the outer automatic locking plate 28 and the inner automatic locking plate 32.

In addition, thanks to the optional elements, the system 1 has a modular character. More specifically, the optional presence of the inner manual locking plate 26 makes it possible to create a visual and tactile indicator module "out of service" inside the toilet when the door 5 is in the "out of manual" state.

The optional presence of the external automatic locking plate 28 makes it possible to create a visual and tactile indicator module "out of automatic service" outside the space 7 when the door 5 is in the "off automatic" state.

The optional presence of the inner automatic locking plate 32 makes it possible to create an "automatic off" visual and tactile indicator module on the inner side A when the door 5 is in the "off automatic" state.
