Description

Technical field of the invention

The present invention relates to an electromechanical device for actuating a lock intended to be mounted on an inner face of an opening movable relative to a wall and equipped with a lock comprising a lock cylinder provided with a rotor, the electromechanical device lock actuator comprising a box provided with a proximal face and fixing elements making it possible to fix the box on the opening by placing the proximal face of the box against the inner face of the opening, and a locking mechanism drive movable in rotation with respect to the housing and intended to be coupled to one end of the rotor of the lock cylinder.

The invention also relates to a method having a step of providing an electromechanical device for operating a lock.

The invention applies in particular to the fields of locks which include a lock cylinder equipped with a rotor with, on the exterior side, an exterior lock entry allowing the introduction of a key admitted by the lock and, on the interior side. , either an interior lock entry allowing the introduction of a key admitted by the lock, or a coupling member allowing the connection of the rotor with a manual button. The rotational actuation of the rotor of the lock cylinder by means of a key or the manual button makes it possible to control the movement of a spring bolt and / or a dead bolt of the lock in order to open or close the door and / or lock or unlock the lock.

The opening may in particular relate to a movable part of a window or of a door.

State of the art

Conventionally, a lock comprises a lock cylinder having a stator fixedly mounted on the opening and a rotor mounted to rotate in the stator so as to pass through the thickness of the opening. The rotational actuation of the rotor of the lock cylinder can actuate in translation a deadbolt of the lock, the latter being movable in translation with respect to the stator and capable of locking the lock by insertion into a keeper secured to a fixed frame, or jamb, on which the sash is mounted movably. The lock may also include a handle pivotally mounted on the opening to actuate at least one spring bolt movable in translation in the stator of the lock. The rotational actuation of the rotor of the lock cylinder can also be used to actuate this spring bolt.

The rotor of the lock cylinder comprises, on the exterior side, an exterior lock entry allowing the introduction of a key admitted by the lock and, on the interior side, either an interior lock entry allowing the introduction of an admitted key by the lock, or a rotor coupling member allowing the installation of a manual button so as to couple in rotation the rotor of the lock cylinder with the manual button. The rotary actuation of the rotor of the lock cylinder by means of a key or the manual button makes it possible to control the movement of a spring bolt and / or a dead bolt of the lock in order to open or close the door and / or lock or unlock the lock.

There are electromechanical devices intended for motorized actuation of such locks, for example in the image of the solution described in the document EP2762661A1 . These electromechanical lock actuation devices are intended to be fixed on the inside of the opening in a manner that cooperates with the rotor of the lock to be motorized with a view to its actuation in order to control its locking and unlocking.

The electromechanical lock actuation devices generally comprise a box to be fixed to an inner face of the opening, the lock of which is to be motorized and a drive mechanism movable in rotation with respect to the box and intended to be coupled to one end of the door. lock cylinder rotor. They also include a source of electrical energy for supplying, on the one hand, an electric actuator suitable for driving the drive mechanism in rotation, and an electronic control unit suitable for communication with the outside, in particular with a view to reception. external instructions and the transmission of outgoing information. The control unit controls the electric actuator taking into account, among other things, these instructions and this information.

It is also known to equip electromechanical lock actuation devices with various sensors, such as movement sensors or position sensors, connected to the control unit which ensures management according to the additional information delivered by these. sensors.

The cooperation between the rotor of the lock cylinder and the drive mechanism internal to the electromechanical lock actuator can be done by placing one of the keys admitted by the lock cylinder at the level of the interior lock entry, this key then being engaged with the drive mechanism to be integral in rotation with one and the other. Alternatively, the cooperation between the rotor of the lock cylinder and the drive mechanism internal to the electromechanical device for operating the lock can take place through the aforementioned coupling member, which can be made integral with the rotor of the cylinder. lock and is intended initially for the installation of the manual button also mentioned above. Once the manual button has been removed, the coupling member can be brought into engagement with the drive mechanism internal to the electromechanical actuating device so that these two elements are integral in rotation with one another.

The electromechanical lock actuation devices must be reversible, that is to say they can be used in combination with a lock mounted on a door opening to the right or opening to the left. In other words, an electromechanical device for actuating a lock must be programmable in order to be indifferently associated with a lock placed on the left side of an opening which is itself articulated on its right side or with a lock placed on the right side of a door. opening itself hinged on its left side. Indeed, depending on whether the lock is placed on the left side or on the right side of the opening, the directions of rotation of the rotor of the lock cylinder required to respectively control the locking of the deadbolt and the unlocking of the deadbolt or even of the spring bolt are reversed. The electromechanical lock actuation device must therefore be aware of the configuration of the lock that it is intended to actuate electrically.

This operation is carried out by configuring, typically programming, the electromechanical device for actuating the lock at the time of its installation.

A first technique for implementing this setting consists of the user carrying out manual programming, but the user is then liable to make errors in the interpretation of the concepts linked to the opening directions of the leaves.

A second technique for implementing the parameterization of the electromechanical lock actuator consists of the electromechanical lock actuator device learning autonomously from a starting position, that is to say that the user initiates a self-learning of the electromechanical device for actuating the lock from a predetermined position of the lock among a locked configuration or a unlocked configuration. During this self-learning, the electromechanical device for actuating the lock seeks to identify the stops of the lock and to deduce the opening direction of the leaf.

Unfortunately, these solutions do not yet give complete satisfaction. In fact, in the two techniques described above, the user is called upon either to inform the type of opening of the leaf on which the lock is mounted, or to inform the predetermined position from which the self-learning is performed. This human factor inevitably induces sources of potential error, liable to lead to an erroneous parameterization of the electromechanical device for actuating the lock. It is possible, for example, to erroneously end up with a setting in which the electromechanical device for actuating the lock seeking to unlock the lock drives its rotor in a direction of rotation leading in practice to its locking, and vice versa.

This problem is all the more important and potentially damaging as the error made may not be detected. In fact, the movement of the lock induced by the electromechanical device for actuating the lock is generally carried out when the opening is closed. The bolts of the lock then being invisible to the user, checking that the lock exerts a movement corresponding to the user's request is delicate and the errors are virtually undetectable visually.

The document US2018 / 142498A1 describes an electromechanical device for actuating a lock comprising a box to be fixed to the inner face of the opening, a drive mechanism movable in rotation with respect to the box and allowing coupling to the rotor of the lock cylinder, and various sensors for define the open or closed state of the leaf. However, this solution still does not make it possible to determine the movements of the opening in a simple manner.

The object of the present invention is to propose an electromechanical device for actuating a lock which responds to the problems raised by the state of the art presented above, in particular which simplifies and makes the initial settings more reliable and which confers good security and ergonomics. improved.

detailed description

On the figures 1 to 4 and in the remainder of the description, the same references represent identical or similar elements. In addition, the various elements are not shown to scale so as to favor the clarity of the figures. Furthermore, the different embodiments and variants are not mutually exclusive and can be combined with one another.

The electromechanical lock actuator 10 which is visible on the figures 2 to 4 is intended to be mounted on an inner face 201 of a leaf 200 equipped with a lock 100, for example for a door pivotally mounted on a fixed frame 401 connecting the leaf 200 to a wall 400. For example, the face interior 201 corresponds to a face of the opening 200 intended to be positioned on the interior side of the part closed by the opening 200 and the wall 400.

The lock 100 comprises, in a known manner, for example as described in the document EP2762661A1 , a lock cylinder having a stator 102 mounted on the leaf 200 and a rotor 101 mounted to rotate in the stator 102 so as to pass through the thickness of the leaf. The rotational actuation of the rotor 101 actuates in translation a bit or a dead bolt 103, as well as optionally a closing bolt 104, also called end-of-travel bolt or spring bolt, able to retractably fit into a keeper secured to the fixed frame 401 on which the 'leaf 200 is mounted, in order to lock or unlock the lock 100 and / or to open or close the leaf 200. The arrangement of such bolts 103, 104 is for example described in the document FR2795120A1 . The lock 100 can also include a handle 105 pivotally mounted on the opening 200 to actuate at least the closing bolt 104. The lock cylinder can be single clutch or double clutch.

The rotor 101 comprises, on the exterior side, an exterior lock entry allowing the introduction of a key 106 admitted by the lock 100, as shown diagrammatically on the diagrams. figures 3 and 4 .

The electromechanical device for actuating the lock 10 can equally well cooperate, with a view to its motorized drive, with a lock cylinder, the rotor 101 of which comprises, on the interior side, either an interior lock entry allowing the introduction of a key 106. admitted by the lock 100, or a coupling member 107 adapted to be driven in rotation, for example by a manual button (not shown). Such a coupling member 107 is for example a tail or a cylinder fork. The motorized actuation of rotor 101 in rotation, whether by means of a key 106 or by means of the coupling member 107, makes it possible to control the movement of the closing bolt 104 and / or of the deadbolt 103 in order to open or close the leaf 200 and / or to lock or unlock the lock 100.

The electromechanical lock actuator 10 comprises a housing 11 in one or more parts, provided with a proximal face 12 and fixing elements 13 allowing the housing 11 to be fixed on the opening 200 in a manner placing the proximal face 12 of the housing 11 against the inner face 201 of the opening 200. The fixing elements 13 are for example in the form of one or more screws placed in corresponding through openings made through a wall of the housing 11 delimiting the proximal face 12, these screws being intended to engage in the opening 200. It is possible to provide for the presence of a damping material between the inner face 201 of the opening 200 and the proximal face 12 of the housing , to provide a damped mechanical connection between the housing 11 and the opening 200 for vibratory and mechanical decoupling.

The electromechanical device for actuating the lock 10 comprises a drive mechanism 14 movable in rotation with respect to the housing 11 and intended to be coupled to one end of the rotor 101 of the lock cylinder, in particular at the level of the end of the rotor 101 located on the inside. This coupling can, as explained above, be achieved by means of a key inserted beforehand into the interior entry of the lock or by means of the coupling member 107. Depending on the variant adopted, the mechanism d The drive 14 is adapted accordingly and comprises suitable rotational coupling elements for cooperation either with the key 106 or with the coupling member 107.

The lock 100 comprises two opposite maximum angular stops, the nature of which is not important here, to limit the displacement of the rotor 101 of the lock cylinder or of the drive mechanism 14 of the electromechanical device for operating the lock 10 at the same time. within a predetermined angular stroke. The assembly can indifferently be configured for an angular travel limited to about a quarter of a turn of the rotor, as is the case for example on the North American market, or for an angular travel of several turns of the rotor, as it is. is the case for example on the European market.

The electromechanical lock actuator 10 may also include a rotary operating button 20 adapted for manual engagement and for manually driving the drive mechanism 14, ultimately allowing the rotor 101 of the lock cylinder to be rotated manually when this rotor 101 is rotatably coupled to the drive mechanism 14.

The electromechanical lock actuation device 10 comprises a movement sensor 16 capable of determining a displacement of the box 11, and therefore of the opening 200 on which the box 11 is fixed, and capable of delivering movement information β representative of the presence or absence of a displacement of the housing 11 and of the opening 200.

The electromechanical lock actuator 10 also comprises a first distance sensor 15 capable of emitting a first beam of waves F directed in a first direction contained in a first half-space E located on a first side of a main plane P oriented vertically when the housing 11 is fixed to the inner face 201 of the leaf 200 and containing the axis of rotation of the drive mechanism 14, which coincides in practice with the axis of rotation of the rotor 101 with respect to to the stator 102. The first wave beam F has a first lateral component X perpendicular to the principal plane P moving away from the principal plane P and a first axial component Y parallel to the axis of rotation of the drive mechanism 14 and s 'approaching the proximal face 12 of the housing 11. The first distance sensor 15 is able to deliver first distance information α representative of a first distance d determined by virtue of the first beam of waves F.

The electromechanical device for actuating the lock 10 further comprises a second distance sensor 15 'distinct from the first distance sensor 15 and capable of emitting a second beam of waves F' directed in a second direction contained in a second half. space E 'located on a second side of the principal plane P. The second wave beam F' has a second lateral component X 'perpendicular to the principal plane P away from the principal plane P and a second axial component Y' parallel to the axis of rotation of the drive mechanism 14 and approaching the proximal face 12 of the housing 11. The second distance sensor 15 'is able to deliver a second distance information α' representative of a second distance of determined by the second beam of waves F '.

In this document, it is therefore understood that all the quantities and components which relate to the second distance sensor 15 ′ are identified by the acronym “′”.

Furthermore, the distances d and d 'associated respectively with the first distance sensor 15 and with the second distance sensor 15' are represented with an index i in the figures corresponding to the instant ti when the distances d and d 'are measured. In other words, on the figure 3 which represents a situation at a time t1, the distance d is marked d1 while the distance is represented by 1. On the other hand on the figure 4 which represents a situation at an instant t2, the distance d is marked d2 while the distance is represented by 2.

The first distance sensor 15 is therefore organized so as to emit the first beam of waves F on one side of the electromechanical device for actuating the lock 10 among the right side and the left side, while the second distance sensor 15 'is arranged so as to emit the second wave beam F' to the other side of the electromechanical lock actuator 10 among the right side and the left side. According to the provisions shown by way of example on the figures 3 and 4 , the first distance sensor 15 is organized so as to emit the first beam of F waves on the left side of the electromechanical device for operating the lock 10 for a user located on the interior side, while the second distance sensor 15 ' is arranged so as to emit the second wave beam F 'on the right side of the electromechanical lock actuator 10 seen from the interior side.

Advantageously but in a nonlimiting manner, the wave beams F, F 'can correspond to optical wave beams (advantageously in the domain invisible to the human eye but potentially in the visible region if necessary) or ultrasonic.

The determination of the distances d and d 'by the distance sensors 15, 15' can in particular be done by using the beams of waves F, F 'in a concrete way using a time of flight put by the beam of waves F , F 'to travel the outward and return distance between the distance sensor concerned and a corresponding reflection surface, on which the wave beam is reflected towards the distance sensor.

The electromechanical lock actuation device 10 also comprises a programmable electronic control unit 17, of microcontroller type, capable of receiving the first distance information α delivered by the first distance sensor 15 and the second distance information α 'delivered by the second distance sensor 15 '. The programmable electronic control unit 17 is also able to receive the movement information β delivered by the movement sensor 16, or generally any information, called initial condition, able to trigger the start-up of the first sensor. distance 15 and / or the second distance sensor 15 '.

The control unit 17 is configured to trigger, when the initial condition is verified, for example according to which the movement information β is representative of the presence of a movement of the box 11 and of the opening 200, the transmission of at least one of the first beam of waves F by the first distance sensor 15 and of the second beam of waves F 'by the second distance sensor 15' and to monitor the evolution of at least one of the first distance d and the second distance d 'during a determined period of time known to the control unit 17.

The determined period of time referred to here can typically be in a range from one hundredth of a second to a few tenths of a second.

A possible use of the electromechanical lock actuator 10 is given below.

The method relating to this use firstly comprises a step of providing such an electromechanical device for actuating a lock 10 comprising the housing 10, the drive mechanism 14, the movement sensor 16, the two distance sensors 15. , 15 'and the control unit 17. The process further comprises a distance control step comprising triggering the emission of at least one of the first beam of waves F by the first distance sensor 15 and of the second beam of waves F 'by the second sensor of distance 15 'then monitoring the evolution of at least one of the first distance d and of the second distance d' during the determined period of time, this distance control step being implemented automatically by the unit control 17 when an initial condition is verified, in particular a condition according to which the movement information β is representative of the presence of a movement of the housing 11 and of the leaf 200.

According to a particular embodiment, the first direction in which the first beam of waves F is emitted by the first distance sensor 15 and the second direction in which the second beam of waves F 'is emitted by the second distance sensor 15 'are oriented so that, when the housing 11 is fixed on the inner face 201 of the opening 200, one of the first beam of waves F and the second beam of waves F' is incident on a surface reflection integral with the opening 200 and the other among the first wave beam F and the second wave beam F 'is incident on a reflection surface integral with the wall 400 or the fixed frame 401 connecting the opening 200 to the wall 400, in particular at least when the opening 200 is closed or almost closed.

In the particular variant, but not limiting, illustrated on the figures 3 and 4 where the sash 200 is a sash with a left-hand lock by pulling (seen from the interior side), the electromechanical lock actuator 10 is positioned on the left vertical side of the sash 200 and the first direction in which the first beam of waves F is emitted by the first distance sensor 15 is oriented so that, when the housing 11 is fixed on the inner face 201 of the opening 200, the first beam of waves F is incident on a surface of reflection integral with the wall 400 or the fixed frame 401 connecting the opening 200 to the wall 200 in particular when the opening 200 is closed or almost closed, while the second direction in which the second wave beam F 'is emitted by the second distance sensor 15 'is oriented so that, when the box 11 is fixed on the inner face 201 of the opening 200, the second wave beam F' is incident on a reflection surface integral with the opening 200 whatever or the position occupied by the opening 200 relative to the wall 400. Thus in this example, the components X, Y are liable to change over time as a function of the position occupied by the opening 200 relative to the wall 400. Conversely, the components X ', Y' are invariable over time regardless of the position occupied by the opening 200 with respect to the wall 400. Reverse configurations would be adopted in the case where the leaf 200 is a leaf with a lock on the right by pulling (seen from the interior side).

According to a particular embodiment, the control unit 17 comprises algorithms making it possible to determine a direction of opening of the leaf 200 relative to the wall 400, typically from a direction of opening to the right and a direction of opening. 'opening to the left, depending on the increase or decrease of one of the first distance d and the second distance d' during the determined period of time following a joint emission, in particular when an initial condition is verified, of the first beam of waves F by the first distance sensor 15 and of the second beam of waves F 'by the second distance sensor 15' and of the monitoring of the evolution of the first distance d and of the second distance of during that determined period of time.

• déclenchement de l'émission du premier faisceau d'ondes F par le premier capteur de distance 15 et de l'émission du deuxième faisceau d'ondes F' par le deuxième capteur de distance 15',
• surveillance de l'évolution de la première distance d et de la deuxième distance d' durant la période de temps déterminée,
• détermination d'un sens d'ouverture de l'ouvrant 200 par rapport à la paroi 400 en fonction de l'augmentation ou de la diminution de l'une parmi la première distance d et la deuxième distance d' durant la période de temps déterminée.

Thus the method is such that during an initialization phase of the electromechanical device for actuating the lock 10, the distance control step comprises the following steps implemented automatically by the control unit 17, preferably when a condition initial is checked:

• triggering of the emission of the first beam of waves F by the first distance sensor 15 and of the emission of the second beam of waves F 'by the second distance sensor 15',
• monitoring of the evolution of the first distance d and of the second distance d 'during the determined period of time,
• determining a direction of opening of the leaf 200 relative to the wall 400 as a function of the increase or decrease of one of the first distance d and the second distance d 'during the determined period of time .

Thus, it is advantageously provided to use two distance sensors 15, 15 'respectively on the two sides of the electromechanical device for actuating the lock 10, analyzing distances d and on either side of the lock 100, to allow to know automatically and advantageously without any human intervention (avoiding any risk of error coming from a human factor), at the time of the installation and the parameterization of the electromechanical device for actuating the lock 10, the direction of rotation of the leaf 200. In other words, it is advantageously carried out a self-learning of the opening direction of the leaf 200 by the use of two separate distance sensors 15, 15 ′. The two distance sensors 15, 15 'are intended to be used jointly only at the time of the initialization phase.

Advantageously, these distance sensors 15, 15 'are only used when an initial condition is verified, for example when a movement of the electromechanical device for actuating the lock 10 and of the opening 200 is detected, and are not used otherwise. In other words, in this example, the motion sensor 16 is used for the decision-making of the detection of a change of state of the opening leaf 200, this change of state detected being the condition for activating the distance sensors. 15, 15 '. Therefore, the distance sensors 15, 15 ', which can advantageously be of high precision compared to a motion sensor and which are very reliable due to their inability to be disturbed by natural or induced variations. 'outside the magnetic field or by the vibrations of the sash 200 (but which are likely to consume significantly more electrical energy than the motion sensor 16), only consume electrical energy at the instants when the initial condition is checked, in the example if the opening 200 is considered to be in motion: consequently, the electromechanical device for actuating the lock 10 nevertheless has a very low power consumption despite its very high measurement accuracy and its high reliability .

Furthermore, because no human intervention is required, the electromechanical lock actuator 10 is very easy to use, reliable, while being user-friendly and ergonomic for the user.

The figure 3 shows an example of the situation of an opening 200 in a closed state with respect to the fixed frame 401 at an instant t1, unlike the figure 4 which shows the situation at a time t2 when the opening 200 is partially closed, that is to say that it has barely been opened so as to release the lock 100 from the fixed frame 401.

On the figure 3 , at the instant t1, the first distance determined by the first distance sensor 15 is marked d1 and the second distance determined by the second distance sensor 15 'is marked with 1. On the figure 4 , at the instant t2, the first distance determined by the first distance sensor 15 is marked d2 and the second distance determined by the second distance sensor 15 'is marked with 2.

The example shown on figures 3 and 4 corresponds to a particular non-limiting application where the opening 200 is mounted on the fixed frame 401 so as to be an opening with a lock on the left by pulling, seen from the interior side. The first distance d1, d2 determined respectively at times t1, t2 corresponds to the distance between the first distance sensor 15 which emits towards the left side of the lock 100 in the direction of the reflection surface integral with the wall 400, and this surface of reflection. The second distance of 1, of 2 determined respectively at times t1, t2 corresponds to the distance between the second distance sensor 15 'which emits towards the right side of the lock 100 in the direction of the reflection surface integral with the opening 200, and this reflection surface. Consequently, it is understood that the first distance d determined is, in this particular case, a distance liable to vary over time as a function of the movements of the opening leaf 200. Conversely, the second distance d 'determined by the second distance sensor 15 'is constant whatever the position of the leaf 200. Consequently, and as can be seen on the figures 3 and 4 , the value d1 taken by the first distance d at time t1 is strictly different from the value d2 taken by the first distance d at time t2. Conversely, the value of 1 taken by the second distance d 'at time t1 is strictly identical to the value of 2 taken by the second distance d' at time t2.

Reverse configurations would be adopted in the event that the leaf 200 is a leaf with a lock on the right by pulling (seen from the interior side).

In the particular case of figures 3 and 4 , due to the passage of the leaf 200 from a closed state to a partially closed state, it is further determined that the value d1 taken by the first distance d at the instant t1 is strictly less than the value d2 taken by the first distance d at time t2.

According to a particular embodiment, in particular following an initialization phase, the control unit 17 is configured to determine, among the first distance sensor 15 and the second distance sensor 15 ', the operational distance sensor which delivers distance information a, α 'representative of an operational distance among the first distance d and the second distance d' which is liable to vary during the period of time determined as a consequence of a movement of the leaf 200 with respect to the wall 400 and, when the condition according to which the movement information β is representative of the presence of a movement of the box 11 and of the opening 200 is verified, to trigger the emission of the wave beam F, F 'by this operational distance sensor and not trigger the emission of the beam of waves F, F' by the other distance sensor among the first distance sensor 15 and the second distance sensor 15, then to monitor the é change in the operational distance during the determined period of time, in particular making it possible to determine that the movement of the leaf 200 is within a predetermined range of movement and / or that the leaf 200 is in one of the following states: open, closed, partially open, partially closed (or almost closed).

Thus, the initialization phase comprises a step of determining, among the first distance sensor 15 and the second distance sensor 15 ', an operational distance sensor which delivers distance information a, α' representative of a operational distance, among the first distance d and the second distance d ', which is liable to vary during the period of time determined as a consequence of a movement of the opening 200 relative to the wall 400.

• déclenchement de l'émission du faisceau d'ondes F, F' par le capteur de distance opérationnel, durant laquelle l'émission du faisceau d'ondes F, F' par l'autre capteur de distance, parmi le premier capteur de distance 15 et le deuxième capteur de distance 15', n'est pas déclenchée,
• surveillance de l'évolution de la distance opérationnelle durant la période de temps déterminée, notamment permettant de déterminer que le mouvement de l'ouvrant 200 se situe dans une plage prédéterminée de mouvement et/ou que l'ouvrant 200 est dans l'un des états suivants : ouvert, fermé, partiellement ouvert, partiellement fermé.

Then after the initialization phase, the method comprises a phase of normal use during which the distance control step comprises the following steps automatically implemented by the control unit 17 when the condition is verified that the movement information β is representative of the presence of a movement of the box 11 and of the leaf 200:

• triggering of the emission of the beam of waves F, F 'by the operational distance sensor, during which the emission of the beam of waves F, F' by the other distance sensor, among the first distance sensor 15 and the second distance sensor 15 ', is not triggered,
• monitoring of the evolution of the operational distance during the determined period of time, in particular making it possible to determine that the movement of the leaf 200 is within a predetermined range of movement and / or that the leaf 200 is in one of the following states: open, closed, partially open, partially closed.

Thus, during the phase of normal use, only one of the distance sensors 15, 15 '(the one intended to determine the distance d, d' likely to be modified over time due to a movement of the opening 200 relative to the wall 400) is used, which makes it possible to optimize electricity consumption. On the other hand, unlike the initialization phase, the other distance sensor 15, 15 ′ is no longer intended to be used for the purpose of controlling the change of state of the leaf 200. On the other hand, it can be subsequently used. used for other possible functions, such as for example the proximity management of a user or an object. The other distance sensor 15, 15 'thus functions for example as a switch, a modification observed in the distance measured by the other distance sensor corresponding for example to an activation of the switch.

In particular, the monitoring of the evolution of the distance d, d determined by the operational distance sensor makes it possible to establish a safety check. Indeed, when the movement sensor 16 has determined a movement information β representative of a movement of the housing 11 and of the opening 200, it is it may be that this movement has actually occurred and that the movement information β corresponds well to a movement of movement between two states of the leaf 200, or that this movement of movement between two states of the leaf 200 has not occurred product concretely and that the motion information β is then false. For example, the movement information can correspond to vibrations undergone by the opening 200, without a final movement of displacement of the opening 200 having taken place. To eliminate the cases of false detections of movement of the opening leaf 200, the distance d, d determined by the operational distance sensor can be used as confirmation of the detections. In particular, in the case where the distance d, d 'determined by the operational distance sensor does not vary within the determined period of time, the control unit 17 can consider that the detection of movement by the movement sensor 16 is likely to be wrong.

The electromechanical lock actuation device 10 also comprises a position sensor 19 capable of determining an angular position of the drive mechanism 14 and capable of delivering position information γ representative of the angular position of the drive mechanism 14 thus determined. by the position sensor 19. The control unit 17 is configured to trigger, when a condition is verified according to which the position information γ is representative of a locking and / or an unlocking of the lock 100 of opening it 200, the emission of at least one of the first beam of waves F by the first distance sensor 15 and of the second beam of waves F 'by the second distance sensor 15' and to monitor the evolution of at least one of the first distance d and of the second distance d 'during the determined period of time. The position information γ representative of the angular position of the drive mechanism 14 thus determined by the position sensor 19 corresponds to an initial condition, capable of triggering the emission of the beam F by the first distance sensor 15 and / or of the beam F 'by the second distance sensor 15' and to activate the monitoring of the distance d and / or the distance d '.

Thus during the normal use phase, the distance control step is implemented automatically by the control unit 17 when a condition is verified according to which the position information γ is representative of a locking and / or unlocking the lock 100 of the leaf 200.

In particular, the monitoring of the evolution of the distance d, d determined by the operational distance sensor makes it possible to establish a safety check. By way of example, the control unit 17 will thus be able to monitor a position or the state (among the partial open state, the total open state or the closed state). partial) of the leaf 200 after unlocking of the lock 100 has been ordered. In addition, the control unit 17 will also be able to check that after a command to lock the lock 100, the distance d, determined by the operational distance sensor does not change: otherwise, this could mean that the lock 100 was locked although the opening 200 was not in a position to cooperate with the fixed frame 401 and although the bolts 103, 103 were not able to fulfill their respective roles.

Each time the operational distance sensor is called upon, the movement sensor 16 undergoes a recalibration step to configure it to its environment after the determined period of time, whether or not a movement of the opening 200 has occurred. In fact, environmental conditions, such as ambient light, for example, the change in the state of reflection of surfaces, can have an impact on the distance measured by the operational sensor. This recalibration can also be carried out automatically each time the position information γ is representative of a locking and / or an unlocking of the lock 100 of the leaf 200.

According to a particular embodiment, the electromechanical lock actuator 10 comprises an electric actuator 18 capable of rotating the drive mechanism 14. The control unit 17 is configured to drive the electric actuator 18 in rotation. taking into account the evolution and / or the value of at least one of the first distance d and of the second distance d 'during the determined period of time.

Thus, the method can include a control step implemented by the control unit 17 after the distance control step, during which the electric actuator 18 is controlled by the control unit 17 taking into account the 'evolution and / or the value of at least one of the first distance d and of the second distance d' during the determined period of time.

By way of example, the control unit 17 can thus decide to condition the control of the lock 100 towards its locking or its unlocking by a suitable control of the electric actuator 18, to a condition linked to the distance d, d 'determined by the operational distance sensor. Typically, a control of the electric actuator 18 inducing the passage of the lock 100 towards its locking or its unlocking will be conditioned on the determination of a distance by the operational distance sensor confirming that the opening is closed in order to guarantee the correct operation of the lock 100 with respect to a keeper secured to the fixed frame 401.

According to a particular embodiment, the motion sensor 16 comprises at least one element chosen from the group comprising a magnetometer and an accelerometer, and at least one of the first distance sensor 15 and of the second distance sensor 15 'comprises at least at least one element selected from the group consisting of an ultrasonic beam distance sensor and an optical beam distance sensor

The use of sensors 15, 15 ', 16 of this nature advantageously makes it possible to have all the advantages presented above: high measurement precision, good reliability and the guarantee of low power consumption.

In order to be able to manually actuate the rotor 101 of the lock cylinder in rotation by means of a key 106 inserted at the level of the exterior lock entry and / or by means of the operating button 20 of the electromechanical device of lock actuation 10, it is necessary to disconnect the rotor 101 from the electric actuator 18. The electromechanical device for actuating the lock 10 for this purpose comprises a clutch mechanism interposed between the drive mechanism 14 and the electric actuator 18 and varying between a disengaged configuration in which the electric actuator 14 is not coupled to the drive mechanism 14 and at least one engaged configuration in which the electric actuator 18 is coupled to the drive mechanism 14.

The electromechanical lock actuator 10 comprises an electrical energy storage device 21, such as stand-alone batteries, for supplying the electrical actuator 18 and the control unit 17.

The control unit 17 is suitable for communication with the outside via means of communication of the radiofrequency, wifi, Bluetooth, or equivalent type such as for example ZIGBEE, Zwave or proprietary protocols, in particular with a view to receiving instructions. external to the control unit 17 and the transmission of outgoing information from the control unit 17. The control unit controls the electric actuator 18 from these external instructions and this outgoing information and as a function of distance sensors 15, 15 ', of the movement sensor 16 and of the position sensor 19 in the manner described above. Other sensors can optionally be integrated into the electromechanical device for actuating the lock 10, for example to determine the mechanical torques of rotation of the rotor 101, the absolute angular position of the rotor 101, its speed of rotation or for determining the presence of a key 106 or of any other element necessary for the operation of the lock 100 or of the electromechanical device for actuating the lock 10.

Advantageously, the control unit 17 emits an alarm signal in certain identified cases of operation: for example if the state of the opening 200 is considered to be partially (or almost) closed according to the information supplied by the 'one of the distance sensors 15, 15' and that the lock 10 is activated to lock the leaf 200, an alarm signal will be sent to the attention of a user to signal that the leaf 200 cannot be Locked. Likewise, an alarm signal may be emitted if the opening 200 remains in a partially open or partially closed state for a period greater than a predetermined period.
