  • the first rotary coupling elements 21 comprise at least one coupling slot 261 delimited by the receiving housing 26 and oriented transversely to the axis of rotation of the rotating drive part.
  • each coupling slot 261 is oriented perpendicular to the axis of rotation of the rotary drive piece 20.
  • the depth of each coupling slot 261 is counted, for its part, parallel to the axis of rotation of the rotary drive part 20.
  • the figures 3, 5 , 6 and 7 illustrate the situation after the insertion of the connecting piece 25 in the receiving housing 26.

  • the receiving housing 26 delimits two separate coupling slots 261 aligned with each other in a direction common passing through the axis of rotation of the rotary drive part 20.
  • the connecting piece 25 then advantageously comprises two coupling wings 251 so that the connecting piece 25 adopts a general shape of a butterfly, as is visible on the figure 2 .
  • the receiving housing 26 and the connecting part 25 are configured so that the insertion of the connecting part 25 in the receiving housing 26 is carried out by a relative displacement collinear with the axis of rotation of the driving part. in rotation 20.
  • the third rotational coupling elements 23 are arranged in an orifice delimited by a central body 252, for example generally cylindrical, of the connecting piece 25 and configured so as to be able to cooperate, after coupling of the connecting piece 25 with the piece rotational drive 20 and after insertion of the coupling member 102 into this orifice, with fourth rotary coupling elements 24 integral with the coupling member 102.
  • Each of the coupling wings 251 extends in particular radially around and from the outside of the central body 252.
  • the third rotational coupling elements 23 are for example formed by radial impressions such as recesses, shoulders or the like, having a shape at least partially complementary to the constituent members of the fourth rotational coupling elements 24.
  • the coupling member 102 has a general fork shape with two arms 102a, 102b, typically parallel to each other axially, and offset radially with respect to each other, while the fourth coupling elements in rotation 24 are precisely formed by these two branches 102a, 102b of the coupling member 102 (visible for example on the figure 1 ) offset radially between them.
  • the third rotational coupling elements 23 are formed in particular on the internal wall of the orifice delimited by the central body 252. They appear here as imprints adopting a shape complementary to the external shape of the two branches 102a, 102b of the coupling member 102.
  • They may also include radial lugs (visible on the figure 8 ) arranged radially projecting towards the inside of the orifice which is delimited by the central body 252, these radial lugs being configured to be inserted in the radial interval which separates the two branches 102a, 102b from the member of coupling 102 at the time of the insertion of the connecting piece 25 on the coupling member 102.
  • This insertion of the radial lugs in the interval which separates the two branches 102a, 102b from the coupling member 102 has the effect of participate in the relative rotation lock between the connecting piece 25 and the coupling member 102.
  • This type of coupling member 102 is extremely widespread and relatively universal, which gives the electromechanical device for actuating the lock very great adaptability to existing lock cylinders.
  • the coupling member 102 has a cylindrical shape or is constituted by a straight rod, for example of rectangular section.
  • the shape of the coupling member is provided so that the coupling member is breakable.
  • this type of coupling member is very widespread and relatively universal, which gives the electromechanical lock actuation device very great adaptability to existing lock cylinders.
  • the third rotating coupling elements delimited by the connecting piece 25 are configured in an appropriate way to adapt by complementary shape, by axial insertion of the connecting piece 25 on the coupling member 102, with the fourth connecting elements. rotation coupling defined by the coupling member 102.
  • the cooperation of the third and fourth coupling elements 23, 24 between them is generally obtained by the insertion of the connecting piece 25 on the coupling member 102, this insertion taking place in particular collinearly with the axis of rotation of the rotating drive piece 20.
  • the figures 2 , 5 , 6 and 7 illustrate the situation after this insertion, unlike the figure 3 which illustrates the situation before the fitting of the connecting piece 25 on the coupling member 102.
  • the coupling member 102 is in one piece with the rotor of the lock cylinder of the lock.
  • the coupling member comes in one piece with the rest of the rotor of the lock cylinder. It is however possible that the coupling member is formed in a separate part from the rest of the rotor of the lock cylinder, these two parts being made integral with each other to be in one piece by any means such as example welding or bonding.
  • the coupling member 102 adopts a generally cylindrical shape, which is the case in the case where the coupling member 102 has the shape of a fork with two branches 102a, 102b and when has the shape of a cylindrical tail or a straight stem. In the latter case, even in the case of a rectangular section, the dimensions of the cutting section are so small that the rectangular flat rod cannot be gripped radially in a manner allowing manual rotation of the coupling member. , and concomitantly the rotor of the lock cylinder.
  • the shape of the coupling member is devoid of radial manual drive means and it is the connecting piece 25, once attached to the coupling member, which allows this manual entry suitable for transmitting sufficient rotary torque to rotate the coupling member and the rotor of the lock cylinder.
  • the coupling mechanism 11 comprises a pushing piece 27 capable of moving in the rotating driving piece 20 along its axis of rotation and coming to bear against the key 106 ( figure 10 ) inserted into the rotor of the lock cylinder 101 when the key 106 cooperates with the first rotating coupling elements 21, or against the connecting piece 25 when the drive mechanism 11 cooperates with the coupling member 102 by means of the interposition of the connecting piece 25.
  • the coupling mechanism 11 also comprises a return element 28, for example constituted by one or more compression springs, urging the pushing piece 27 in a direction directed towards the rotor of the lock cylinder 101.
  • the key 106 inserted in the rotor of the lock cylinder 101 is biased by the pushing piece 27 in opposition to a displacement of the pushing piece 27 imposed by the key 106 relative to the piece rotary drive 20 along the axis of rotation of the rotary drive part 20 in a direction away from the lock cylinder 101.
  • These arrangements allow the key 106 not to inadvertently come out of the rotor of the lock cylinder 101, in particular in the event of a clapper flap 200.
  • the electromechanical lock actuation device 10 comprises recognition elements making it possible to identify, when the coupling mechanism 11 is rotatably attached to the rotor of the lock cylinder 101, whether the rotary drive part 20 is coupled in rotation with a key 106 inserted in the rotor of the lock cylinder 101 and cooperating with the first rotary coupling elements 21 carried by the rotary drive part or if the rotary drive part 20 is coupled in rotation with the connecting part 25, the second rotation coupling elements 22 of which cooperate with the first rotation coupling elements 21 carried by the rotation drive part 20.
  • Such recognition elements can be obtained by presence or object recognition sensors from a key 106 and a coupling member 102 or for example by sensors for recognizing the shape of the back plate of the case 18 used, the shape of this plate being adapted to the nature of the lock cylinder 101 used, that is to say as a function of the fact that it has an interior lock entry for the introduction of a key 106 or a locking member coupling 102 permanently present.
