In the coupled state of the auxiliary bolt 9, as visible in FIG. 1, the spacer tube 21 is located in the vicinity of the end 22 a of the oblong hole 22.
- the releasable coupling of bolt 8 and auxiliary bolt 9 is made by means of a fuse element 20 at low temperature of fusion, rigid at room temperature when using the lock (see figure 1).
- the fuse element 20 may for example consist of a plastic material, said low melting temperature being for example of the order of 180 ° C.
- the fusible element 20 comprises a plastic rod, visible in FIG. 1, housed in the vicinity of the end 22b of the oblong hole 22 and occupying a substantial part of the space complementary to the spacer tube 21 in the oblong hole 22, so as to prevent the angular displacement of the spacer tube 21 relative to the bolt 8.

- the bolt 8 and the bolt auxiliary 9 are thus linked in rotation about the axis of rotation 10.
- the torque is transmitted to the bolt auxiliary 9 by means of the fuse element 20 which comes in abutment on the spacer tube 21 in the first variant of the invention, or the coupling pin 11 which abuts on said element fuse in the second variant of the invention, so that the auxiliary bolt is also driven in the open position of the lock.
- the fusible element 20 loses its rigidity following the rise in ambient temperature up to the vicinity of its melting temperature. This loss of rigidity occurs before the melting of said bolt 8, before or at the latest at the start of the sliding stroke of the bolt 8 on the strike 5 under the effect of the differential pressure exerted on the leaf 2 and / or of the expansion of said leaf 2. The fusible element 20 is then no longer able to resist the force exerted by the spring 19 on the auxiliary bolt 9 in the opening direction of the latter.
- auxiliary bolt 9 The rotational connection of the auxiliary bolt 9 with the bolt 8 is then eliminated, the spacer tube being able to slide freely angularly towards the end 22 b of the oblong hole 22 and the coupling pin 11 being able to slide freely angularly towards the end 15 a lights 15.

- the keeper 5 is fire resistant, for example made of steel or cast iron, and has a hollow boss 23 of substantially rectangular parallelepiped shape with rounded edges for ergonomic reasons, which can be obtained for example by stamping a sheet metal steel, and the base 23a is extended along the short sides by two fastening flanges 24 to be applied on a striker carrier 25 so that the long side of the base 23a parallel to the axis of rotation 10; the support 25 being fixed either to the frame of a single door, or to the second leaf 6 of a double door.
- the fixing wings 24 have holes 24 a intended to receive fixing screws (not shown) for fixing the keeper 5 to the support 25.
- the surface portion 5 a of the keeper 5 faces the bolt 3 in closed position of the door and is rounded with a larger radius of curvature than the other edges of the striker 5 to ensure sufficient contact surface with the bolt 8 in the closed position of the lock.
- the surface portion 5 a has two grooves 26 extending perpendicular to the axis 10 and located respectively opposite the edges 17 of the flanges 9 a and 9 b of the auxiliary bolt 9, so that the edges 17 do not enter not in contact with the strike 5 when the lock works with the two bolts 8 and 9 coupled (see figure 1).
- the auxiliary bolt 9 When, the door being initially closed, the auxiliary bolt 9 is brought into its decoupled position (see FIG. 2) following the melting of the fuse element 20, due for example to a fire, if the leaf 2 of the door is pushed in the direction of its opening under the effect of the pressure differential which is exerted on its faces and / or its expansion, the bolt 8 can slide on the keeper 5, for example due to the low coefficient of friction Zamak® on the steel, without causing the bolt 9.
- This sliding of the bolt 8 is due to the fact that the force exerted by the keeper 5 on the bolt 8 in reaction to the pressure force exerted perpendicularly on the leaf 2 and transmitted to the bolt 8 via the axis 10, may include a component whose moment relative to the axis of rotation 10 tends to cause the bolt 8 to enter the housing 1.
- the leaf 2 is curved or rotates a small angle on the axis of its hinges (not shown) in its d opening irection, so that the midpoint of the leaf 2 which carries the housing 1 has an offset d in the opening direction of the door relative to the leaf 6 carrying the keeper 5.
- the edges 17 of the flanges 9 a and 9 b of the auxiliary bolt 9 come into contact with the bottom of the grooves 26 of the keeper 5.
- the auxiliary bolt 9 and the keeper 5 being made of material resistant to fire, for example in steel, and the coefficient of friction of the steel on itself being higher, the blocking of the door in the substantially closed position, called the fire closing position, is then ensured, even after complete melting of the bolt 8 , as shown in Figure 3.
- the ambient temperature having largely exceeded 200 ° C when this occurs, the lock is no longer intended to be opened using the operating member at this stage.
- the coupling pin 11 can be driven by the bolt 8 and lose contact with the case 1; but it is subsequently pushed back into abutment against the wing 1 a by the auxiliary bolt 9.
- the edges 17 of the flanges 9 a and 9 b have notches 27 intended to hang on the front edge 26 has grooves 26 during the movement of the housing 1 in the opening direction of the door, said notches 27 facing said front edge 26 has grooves 26 when the auxiliary bolt is in the decoupled position, as visible in FIG. 2.
- the flanges 9 a and 9 b are hung on the front edges 26 has grooves 26 of the keeper 5, so as to prevent the sliding of the auxiliary bolt 9 on the keeper 5.
- the maximum offset d that can present the midpoint of the leaf 2 on which is mounted the housing 1 of the lock is then determined by the position of the notches 27 and by the phase shift angle which the auxiliary bolt 9 has turned in its decoupled position.
- This offset d is in fact substantially equal to the distance between the bottom of the notch 27 and the rim 26 a of the groove 26 facing it when the fuse element 20 has melted and the bolt 8 has remained in the closed position. of the lock without sliding on the keeper 5 (see figure 2).
- the leaf 2 of the door on which the lock is mounted has an intumescent seal 28 inserted in a housing hollowed out over the entire height of said leaf 2 substantially in the middle of its edge 2a.
- this intumescent joint expands so as to obstruct day 29 which exists between the two leaves 2 and 6 of a double door or between a door and the door frame, in order to make the door more airtight, as visible in FIG. 2.
- the phase shift of the auxiliary bolt 9 is such that the offset d presented by the midpoint of leaf 2 on which is mounted the housing 1 of the lock is substantially less than half the thickness of the second leaf 6 in the case of a double door, or the frame in the case of a single door (not shown), so that the intumescent seal 28 inflated comes into contact with the edge 6a of the second leaf 6 in the case of a double door or the door frame in the case of a single door, so as to maintain the function of fire tightness of the door.
