  • the lever 104 can be adapted to cooperate with the second bolt 100 so that a rotation of the outer square 50 about the first axis X1 is suitable for causing a movement of the second bolt 100 between the extended position and the retracted position.
  • the rotation of the outer square 50 being independent of the rotation of the inner square 10, the rotation of the outer square 50 causes the second bolt 100 to move between the extended and retracted position, but does not cause the bolt 60 to move between the locked position. and the unlocked position.
  • the mechanism leading to the movement of the bolt 60 between the locked position and the unlocked position is as follows.
  • the bolt 60 is in the locked position, and the lock is in the first configuration, the indexing pin corresponding to the first nut 30.
  • the bolt 60 may have been moved to the locked position by actuation of a key in the lock, from inside or outside.
  • the inner square 10 is in a first angular position.
  • the inner square 10 is actuated in rotation about the first axis X1 towards a second angular position.
  • the inner square 10 can be operated by an individual by means of a handle mounted on the inner square 10 and integral with the latter in rotation about the first axis X1.
  • the rotation of the inner square 10 around the first axis X1 causes a corresponding rotation of the driver 20, of the indexing follower 30 and of the fork 40, these elements being integral in rotation about the first axis X1 of each other.
  • the fork 40 comes into contact with the link 70.
  • the branch 41 of the fork 40 can come into contact with the first end 71 of the link 70.
  • the fork 40 exerts a force on the first end 71 of the link 70 so as to cause a displacement of the link 70.
  • the movement of the first end 71 of the link 70 can cause a movement of the third end 73 of the link 70 via the pivot point 74 of the link 70.
  • the movement of the third end 73 of the link 70 which is articulated on the locking piece 80, leads to move the locking piece 80, initially located in position in contact with the bolt 60, to the position without contact with the bolt 60, as illustrated by way of illustration. 'example in figure 6 .
  • the locking piece 80 can in particular reach the position without contact with the bolt 60 when the inner square 10 reaches a second intermediate angular position.
  • the hook of the third end 73 of the connecting rod 70 can, by cooperation with the groove 82 of the locking piece 80, move the locking piece 80 in translation along the third axis X3, until the teeth 81 of the locking piece 80 are no longer in contact with the slots 611 of the bolt 60, when the inner square 10 reaches the second intermediate angular position.
  • the second end 72 of the link 70 can exert a force on the first end 91 of the return lever of the bolt 90, which leads to a displacement of the second end 92 of the return lever of the bolt 90 via the point of pivot 93 of the bolt return lever 90.
  • the second end 92 of the bolt return lever 90 which is in contact with the pin 612 of the bolt 60, then exerts a force on the pin 612 of the bolt 60 in the direction of the second axis X2, which generates a translation of the bolt 60 along the second axis X2 towards the unlocked position.
  • the displacement of the first end 91 of the return lever of the bolt 90 on the pin 612 can be facilitated by the elastic means 94, such as a spring, located in contact with the return lever of the bolt 90.
  • the bolt 60 In a second angular position of the inner square 10, the bolt 60 reaches the unlocked position, as illustrated by way of example in figure 7 . More specifically, the locking end 62 of the bolt 60 no longer protrudes out of the lock, so that the door can be operated by an individual located inside the room.
  • the unlocking mechanism of the emergency lock allows an individual located inside a room to move the bolt 60 from the locked position to the unlocked position by a rotary actuation of the inner square 10.
  • the rotation of the inner square 10 also causes the following sequence.
  • the second bolt 100 is initially in the extended position, its locking end 102 projecting out of the lock, thus blocking the movement of the door.
  • the indexing nut 30 comes into contact with the stop 103 of the shaft 101 of the second bolt 100.
  • the indexing nut 30 then exerts a force on the stop 103, which tends to move the second bolt 100 to the retracted position.
  • the branch 32 of the indexing pin 30 comes into contact with the annular stop 103 of the shaft 101 and exerts a force in the direction of the second axis X2 on the annular stop 103, which causes a translation along the second axis X2 of the stop 103 of the second bolt 100, therefore of the second bolt 100.
  • the second bolt 100 is thus moved until it reaches the retracted position, in which the locking end 102 does not project out of the lock, thus allowing movement of the door.
  • the mechanisms described in the preceding paragraphs can operate when the indexing follower is the second follower 110, a rotation of the inner square 10 then causing a corresponding rotation of the indexing follower 110, causing a rotation of the fork 40 put. in position in the housing 114 of the indexing pin 110, causing the bolt 60 to move between the extended position and the retracted position.
  • the lock makes it possible to resist an outward pulling action of an individual on the outer square 50, as illustrated by way of example in figure 8 . It thus offers an anti-break-in guarantee, for example during a pulling action towards the outside on a handle mounted on the outer square 50 and integral with the latter in translation.
  • the ring 55 placed in a groove 54 of the outer square 50 then abuts against the inner square 10.
  • the tensile force F exerted on the outer square 50 is therefore transmitted to the inner square 10, and transmitted to Coach 20's turn, the inner square abutting against the second part 22 of coach 20.
  • the first part 21 of the driver 20 is in abutment against the indexing follower 30, which blocks the translation along the first axis X1 of the driver 20 and of the inner square 10.
  • the second part 22 of the driver 20 is placed in the indexing follower 30 and the fork 40 is placed in the housing 34 of the indexing follower 30. Furthermore, the fork 40 is held in place between the contact face 53 of the outer square 50 and the housing 34 of the indexing pin 30. Thus, the indexing pin 30 and the fork 40 are held in position relative to each other at the level of the second part 22 of the trainer 20, between the first part 21 of the trainer 20 and the contact face 53 of the outer square 50.
  • the fork 40 remains in position in the housing 34 of the indexing pin 30.
  • the emergency opening function of the lock will continue. therefore to operate for an individual located inside the room, even in the event of actuation of the outer square 50 by an individual located outside the room.
  • the mechanism for retracting the second bolt 100 by rotating the outer square 50 around the first axis X1 is as follows.
  • the lever 104 comes into contact with the stop 103 of the shaft 101 of the second bolt 100.
  • the lever 104 then exerts a force on the stop 103, which tends to move the second bolt 100. towards the retracted position.
  • the lever 104 exerts a force in the direction of the second axis X2 on the annular stopper 103, which causes a translation of the stopper 103 of the second bolt 100, therefore of the second bolt 100, along the second axis X2.
  • the second bolt 100 is thus moved until it reaches the position in which the locking end 102 does not project out of the lock, thus allowing movement of the door.
  • the inner square 10, the driver 20, the indexing follower 30 and the fork 40 are not moved during the rotation of the outer square 50.
  • the output mechanism of the second bolt 100 initially in the retracted position by a rotation of the outer square 50 about the first axis X1 corresponds to the reverse mechanism.
  • the steps of installing the elements of the lock with respect to each other can be carried out in any other possible order.
  • the lock can be reversible, that is to say that a lock initially intended to be installed on the right can be adapted to be installed on the left, and vice versa.
  • a first configuration of the lock has been described, in which the first follower 30 is the indexing follower.
  • the second follower 110 is the indexing follower and the fork 40 is indexed to the second follower 110.
  • the indexing follower 110 is then secured to the drive 20 in rotation about the first axis X1, while the first follower 30 may be integral with the outer square 50 in rotation about the first axis X1.
  • the fork 40 may be, in the first configuration, placed in position in the housing 34 of the first follower 30, or may be, in the second configuration, placed. in position in the housing 114 of the second follower 110.
  • the follower 30, 110 in the housing of which the fork 40 is placed is the indexing follower, which is integral with the driver 20 in rotation about the first axis X1.
  • the steps for changing the direction of the lock can be carried out in any other possible order.
  • the latch bolt 60 can be turned over before removing the inner square 10, the outer square 50 and the driver 20.
  • the outer square 50 and the driver 20 can be removed from the lock separately or simultaneously while remaining assembled to each other, then replaced separately or simultaneously.
  • a door comprising an emergency lock as described above offers advantages similar to the advantages of the lock in terms of emergency opening of the door and guarantee against burglary.
