Description

The present invention relates to the field of devices making it possible, on the one hand, to electrically lock and unlock a movable panel and / or on the other hand to electrically open and close a movable panel.

The present invention relates more particularly to an electric locking-unlocking and electric opening-closing device of a shutter of the window, door or patio door type, said shutter comprising a frame and an opening which is movable in rotation by relative to the frame according to a vertical axis of rotation and / or according to a horizontal axis of rotation, said device comprising an electric motor as well as a movable arm thanks to said electric motor, the opening comprising a locking / unlocking mechanism comprising a set of linkage.

The prior art knows the patent application European N ° EP 1 312 742 an electric locking-unlocking and electric opening-closing device for a shutter using a compass system.

In this document, there is a way to attach / detach an element (a pin) of the opening which is particular, in the form of a hook which can be opened and closed again under the action of the motor.

It is this means which makes it possible to open or close the window manually, without the aid of the device.

The mechanical elements of this device of the prior art which are in mechanical contact with each other during the opening and closing of the hook are necessarily subject to wear.

The reliability over time of the reclosable hook system of the prior art could be improved.

The present invention provides a very reliable means for attaching / detaching an element of the opening. This means comprises a lock which is movable along an axis and which is massive. It is thus very resistant to wear.

The present invention thus relates to an electric locking-unlocking device according to claim 1. This electric locking-unlocking device may also be an electric opening-closing device for a shutter of the window, door or French window type. Said shutter comprises a frame and an opening which is movable in rotation with respect to the frame according to a vertical axis of rotation and / or according to a horizontal axis of rotation. Said device comprises an electric motor as well as a movable arm thanks to said electric motor. The sash has a locking / unlocking mechanism comprising a linkage assembly. Said arm comprises a means for attaching-detaching a pin attached to said linkage assembly which is openable and reclosable under the action of said motor.

• un anneau fermé sur lui-même et présentant un trou débouchant sur une face inférieure et sur une face supérieure,
• un axe de rotation horizontal situé entre ces deux faces et à côté dudit trou
• au moins une aile, située de l'autre côté de l'anneau par rapport audit axe de rotation, et
• au moins un aimant, et de préférence deux aimants situé(s) en face inférieure et réalisant une force de retenue dudit anneau contre ledit bras,

et en ce que ladite aile présente une face inférieure qui est en biseau en direction d'une face supérieure de l'aile afin qu'une translation horizontale vers l'arrière dudit verrou provoque la rotation dudit verrou autour de son axe à l'encontre de ladite force de retenue, par glissement de l'aile sur une butée indépendante dudit bras et qu'un pion attaché audit ensemble de tringlerie puisse pénétrer dans ledit trou ou en être extrait.Said electric locking-unlocking and / or electric opening-closing device remarkable in that said arm comprises a lock having:

• a ring closed on itself and having a hole opening on a lower face and on an upper face,
• a horizontal axis of rotation located between these two faces and next to said hole
• at least one wing, located on the other side of the ring with respect to said axis of rotation, and
• at least one magnet, and preferably two magnets located on the lower face and providing a retaining force of said ring against said arm,

and in that said wing has a lower face which is bevelled towards an upper face of the wing so that a horizontal translation rearwardly of said lock causes said lock to rotate about its axis against of said retaining force, by sliding the wing on a stop independent of said arm and a pin attached to said linkage assembly can enter said hole or be extracted therefrom.

The horizontal translation towards the rear of said lock is carried out by the translation of said arm driven by said motor.

Said device comprises a casing to be fixed to said frame and housing said electric motor, and said arm is movable relative to said casing.

Thus, by this rotational movement of the ring of the lock relative to the axis of rotation of the lock, the pin can be gripped firmly and there is no point physical contact liable to cause premature wear, but surface physical contact.

Said lock preferably comprises two wings located on the other side of the ring relative to said axis of rotation and separated from one another, each wing sliding on a stop independent of said arm so that said pin can penetrate in said hole or be extracted therefrom. Thanks to these two wings, the wing-thrust friction on each wing is halved and wear resistance is further improved.

Said horizontal rearward translation preferably causes the tensioning of an attenuating spring and a forward translation is carried out to cause the lower face to return against said arm under the effect of the force. retaining force, this force being attenuated by the release of said attenuating spring. Thus the contact between the lower face of the lock and the upper face of the arm is softened. The wear resistance is further improved and there is no risk of a "clicking" noise.

The upper face and the lower face of said ring are bevelled, said ring being thicker near said axis of rotation, so that the lock is even more massive and therefore even more resistant.

Said pin preferably has a flared head, an interior section of the hole being greater than an exterior section of said head, in order to facilitate gripping of the pin by the ring of the lock.

The hole is preferably of circular inner section and said head is preferably of circular outer section, with the inner diameter of said hole being greater than the outer diameter of said head.

Said arm ends under the lock, preferably in a flat U-shape whose opening is at least as wide as the width of said hole and whose branches of the U are located opposite two magnets of said lock . Thus, the same device can be used whatever the direction of rotation, to the left or to the right, up or down, of the opening vis-à-vis the frame.

Said casing preferably comprises at least one stopper, and more preferably two stops which has (each) a rounded shape downwards in order to allow the opening and closing of the lock by sliding a wing and preferably of each wing.

The device furthermore preferably comprises a presence sensor for detecting the presence of the pin.

The electric locking-unlocking and electric opening-closing device comprises a casing which is fixed to the frame, which itself is fixed in the opening which the closure must allow to be closed.

This housing is closed and houses the electric motor, but the arm is located outside the housing.

Said stop (or said stops) on which (or which) slide (s) the wing (or wings) of the lock is (or are) preferably fixed, that is to say fixed (s) or belonging to the casing of said device.

The opening preferably comprises a locking-unlocking mechanism comprising at least one movable handle and attached to the linkage assembly.

This handle is preferably movable between a locking position in which the opening is held against the frame and an unlocking position in which the opening is free to open or close relative to said frame.

The handle may be protruding, of the "L" type and allowing locking-unlocking by rotation about a horizontal axis; it can also be embedded and allow locking-unlocking by translation in a horizontal or vertical direction.

The pin referred to here is different from a bolt in the sense that during locking-unlocking, a pin is driven in a translational movement in a direction which is parallel to the adjacent upright of the frame while during locking -Unlocking, a bolt is driven in a translational movement in a direction which is perpendicular to the adjacent upright of the frame.

Preferably, said pin is not a pin which cooperates with a specific cavity made in the frame of the frame; this pin is in mechanical contact only with the arm of said device (that is to say more precisely than with the lock of the arm).

The present invention also relates to a shutter of the window, door or French window type, comprising a frame and an opening which is movable in rotation with respect to the frame at least along a vertical axis of rotation and / or along an axis of rotation. horizontal, and further comprising at least an electric locking-unlocking and / or electric opening-closing device according to the invention, said device preferably being positioned in a top post of said frame.

Advantageously, the present invention makes it possible to grip the pin which is very reliable because it limits the point mechanical contacts.

Again advantageously, the present invention allows the device to be easily used for opening by vertical rotation to the left or to the right.

SPECIFIC TONGUE HOOK

The prior art knows the patent application European N ° EP 1 312 742 an electric locking-unlocking and electric opening-closing device for a shutter using a compass system.

In this document, there is a means for attaching-detaching an element of the opening which is particular, in the form of a hook which can be opened and closed again under the action of the motor.

This document proposes a solution to allow electrically locking-unlocking an opening vis-à-vis a frame and possibly allowing manual locking-unlocking of an opening vis-à-vis a frame.

This document also proposes a solution for making it possible to manually unlock the opening even if the opening has been electrically locked and to manually lock the opening even if the opening has been electrically unlocked.

Thus, in the latter case, even if the power supply to the device is cut after the electric unlocking, it is still possible to manually lock the opening.

Completely independently, a device for locking and unlocking electrically a shutter of the window, door or patio door type is thus disclosed, said shutter comprising a frame and an opening which can be opened "à la française" or "Tilt and turn" and which is movable in rotation with respect to the frame at least along a vertical axis of rotation, said device comprising an electric motor as well as an arm movable by means of said electric motor, the opening comprising a locking mechanism. release and a set of linkage.

Said locking-unlocking mechanism optionally comprises at least one movable handle and said linkage assembly is then attached to said handle, said handle being movable between a locking position in which the leaf is held against the frame and an unlocking position in which the opening is free to open or close with respect to said frame.

• Ledit bras comporte d'une part un crochet présentant une ouverture orientée vers un pion attaché audit ensemble de tringlerie et mobile avec cet ensemble de tringlerie, ladite ouverture étant destinée à l'accueil dudit pion lorsque l'ouvrant est fermé et d'autre part une languette qui est liée mécaniquement audit bras et s'étend au-dessus d'une partie seulement de ladite ouverture, afin que pour le verrouillage électrique de l'ouvrant (ou de ladite poignée), ledit pion passe sous ladite languette lors de la fermeture de l'ouvrant contre le dormant et retienne ledit pion pour empêcher l'ouverture de l'ouvrant jusqu'au verrouillage électrique grâce audit moteur électrique.
• Ainsi, lorsque l'ouvrant est en position fermée contre le dormant mais que la poignée est déverrouillée, de permettre de maintenir l'ouvrant contre le dormant : il s'agit donc d'empêcher que l'ouvrant ne s'ouvre sous l'effet d'un vent venant de l'extérieur ou sous l'effet des joints qui garantisse l'étanchéité aux vents entre l'ouvrant et le dormant.
• La languette exerce ainsi un effort de retenu sur le pion et retient ainsi l'ouvrant en position fermé ; toutefois, un effort manuel contraire à cet effort de retenu permet de libérer le pion et permet ainsi d'ouvrir l'ouvrant.
• La languette présente de préférence une longueur sensiblement identique à la longueur dudit pion et la partie de ladite ouverture qui n'est pas recouverte par ladite languette présente une largeur correspondant à la course dudit pion lors du verrouillage-déverrouillage.
• Ledit pion présente une tête évasée et ladite languette présente un retour à une extrémité opposée à sa liaison avec ledit bras pour retenir ladite tête.
• Le dispositif comporte en outre ; de préférence, un capteur de présence pour détecter la présence dudit pion sous ladite languette et déclencher le verrouillage électrique. Ceci augmente la fiabilité du dispositif.
• La languette comporte alors de préférence un trou pour la détection optique de la présence dudit pion sous ladite languette.
• De préférence, le pion n'est pas un pion qui coopère avec une cavité spécifique ménagée dans le dormant : il est présent spécifiquement pour permettre le fonctionnement du dispositif. Ce pion est en contact mécanique qu'avec le bras dudit dispositif.
• Ledit crochet est, de préférence, situé à une extrémité dudit bras et ledit bras est attaché à une vis sans fin à une autre extrémité, pour opérer un mouvement uniquement de translation selon une direction générale qui est, de préférence, horizontale.

The additional features of this electric locking and unlocking device are as follows:

• Said arm comprises on the one hand a hook having an opening oriented towards a pin attached to said linkage assembly and movable with this linkage assembly, said opening being intended to receive said pin when the opening is closed and on the other hand a tongue which is mechanically linked to said arm and extends above only a part of said opening, so that for the electrical locking of the opening (or of said handle), said pin passes under said tongue during the closing of the opening against the frame and retains said pin to prevent the opening of the opening until electrically locking by means of said electric motor.
• Thus, when the sash is in the closed position against the frame but the handle is unlocked, to allow the sash to be held against the frame: it is therefore a matter of preventing the sash from opening under the effect of a wind coming from the outside or under the effect of the joints which guarantees the wind tightness between the sash and the frame.
• The tongue thus exerts a retaining force on the pin and thus retains the opening in the closed position; however, a manual effort contrary to this retention effort frees the pin and thus allows the opening to be opened.
• The tongue preferably has a length substantially identical to the length of said pin and the part of said opening which is not covered by said tongue has a width corresponding to the travel of said pin during locking-unlocking.
• Said pin has a flared head and said tab has a return at an end opposite to its connection with said arm to retain said head.
• The device further comprises; preferably, a presence sensor for detecting the presence of said pin under said tab and triggering the electrical locking. This increases the reliability of the device.
• The tab then preferably comprises a hole for the optical detection of the presence of said pin under said tab.
• Preferably, the pin is not a pin which cooperates with a specific cavity made in the frame: it is present specifically to allow the device to operate. This pin is in mechanical contact only with the arm of said device.
• Said hook is preferably located at one end of said arm and said arm is attached to a worm at another end, in order to effect a translational movement only in a general direction which is preferably horizontal.

• Le dispositif de verrouillage-déverrouillage électrique comporte un carter qui est fixé au dormant, qui lui-même est fixé dans la baie que l'obturation doit permettre d'obturer.
• Ce carter est fermé et abrite le moteur électrique mais le bras est situé en dehors du carter.
• Le pion auquel il est fait référence ici est différent d'un pêne dans le sens où lors du verrouillage-déverrouillage, un pion est animé d'un mouvement de translation selon une direction qui est parallèle au montant adjacent du dormant alors que lors du verrouillage-déverrouillage, un pêne est animé d'un mouvement de translation selon une direction qui est perpendiculaire au montant adjacent du dormant.
• La poignée à laquelle est liée le pion peut être saillante, de type « en L » et permettant le verrouillage-déverrouillage par rotation selon un axe horizontal ; elle peut être aussi être encastrée et permettre le verrouillage-déverrouillage par translation selon une direction horizontale ou verticale.
• Une obturation de type fenêtre, porte ou porte-fenêtre, est en outre divulguée, comportant un dormant et un ouvrant qui est ouvrable « à la française » ou « oscillo-battante » et qui est mobile en rotation par rapport au dormant au moins selon un axe de rotation vertical et comportant en outre au moins dispositif de verrouillage et déverrouillage électrique avec le crochet à languette spécifique, voire deux dispositifs de verrouillage et déverrouillage électrique avec chacun le crochet à languette spécifique, ledit dispositif ou lesdits dispositifs étant de préférence positionné(s) dans un montant haut et/ou dans un montant bas dudit dormant.
• Avantageusement le crochet à languette spécifique permet ainsi verrouiller-déverrouiller électriquement un ouvrant, mais elle permet surtout de verrouiller l'ouvrant manuellement, même si l'ouvrant a été auparavant déverrouillé électriquement ou de verrouiller l'ouvrant électriquement, même si l'ouvrant a été auparavant déverrouillé manuellement.
• Avantageusement le crochet à languette spécifique permet ainsi d'attraper le pion attaché à l'ouvrant pour permettre le verrouillage électrique que ce dernier ait été ouvert manuellement ou électriquement.
• Avantageusement encore, le crochet à languette spécifique permet d'éviter d'utiliser une gâche électrique spécifique qui est difficile à installer lorsqu'il est souhaité conserver un verrouillage-déverrouillage manuel.
• Avantageusement enfin, le crochet à languette spécifique réalise une solution qui est fiable, robuste et peu onéreuse à fabriquer et à utiliser.

Said hook and said arm are preferably integral and are more preferably made from a single piece of metal plate.

• The electric locking-unlocking device comprises a casing which is fixed to the frame, which itself is fixed in the opening which the closure must allow to be closed.
• This housing is closed and houses the electric motor, but the arm is located outside the housing.
• The pin referred to here is different from a bolt in the sense that during locking-unlocking, a pin is driven in a translational movement in a direction which is parallel to the adjacent upright of the frame while during locking -Unlocking, a bolt is driven in a translational movement in a direction which is perpendicular to the adjacent upright of the frame.
• The handle to which the pin is linked may be projecting, of the “L” type and allowing locking-unlocking by rotation about a horizontal axis; it can also be embedded and allow locking-unlocking by translation in a horizontal or vertical direction.
• A shutter of the window, door or patio door type is also disclosed, comprising a frame and an opening which can be opened "à la française" or "tilt-turn" and which is movable in rotation with respect to the frame at least according to a vertical axis of rotation and further comprising at least an electrical locking and unlocking device with the specific tongue hook, or even two electrical locking and unlocking devices each with the specific tongue hook, said device or devices preferably being positioned ( s) in a high upright and / or in a low upright of said frame.
• Advantageously, the hook with a specific tongue thus makes it possible to electrically lock-unlock an opening, but above all it makes it possible to lock the opening manually, even if the opening has been previously unlocked electrically or to lock the opening electrically, even if the opening has previously unlocked manually.
• Advantageously, the hook with a specific tongue thus makes it possible to catch the pin attached to the opening to allow electrical locking whether the latter has been opened manually or electrically.
• Again advantageously, the hook with a specific tongue makes it possible to avoid using a specific electric strike which is difficult to install when it is desired to keep a manual locking-unlocking.
• Finally, advantageously, the hook with a specific tongue provides a solution which is reliable, robust and inexpensive to manufacture and to use.

It is specified that in these figures the elements in the background are not always represented but that in these figures the proportions between the various elements represented are respected, in order to facilitate reading. The embodiments of figures 1 to 10 do not form part of the present invention.

In the following description, an example of a window type shutter is taken; however, the present invention applies to any type of shutter and in particular to a door or a French window.

The figures 1 to 3 illustrate the opening movement of a shutter 1 which is here a "French-style" window, the window itself being able to simply be "French-style" or "tilt-and-turn", respectively in the window closed position handle locked ( figure 1 ), in the window closed position, handle unlocked ( figure 2 ) and in the window open position ( figure 3 ).

This window comprises a fixed frame, or "frame 2", as well as an opening 3 which is movable relative to the frame according to an axis of rotation Rv, which is in the case of the French opening, an axis of rotation vertical.

On the figures 1 to 3 , the window is positioned inclined in order to make it possible to better visualize the movement of the opening with respect to the frame, but in reality, the window is intended to be positioned vertically and the axis of rotation Rv is thus vertical.

Throughout this document, the length is considered horizontally in the left-right direction in figure 1 and the height is considered vertically, also with reference to the figure 1 . Considerations of the "above" or "below" type are made with reference to this guidance.

The opening 3 comprises a locking-unlocking mechanism 30 which is located against the vertical edge of the opening which is furthest from the axis Rv. This mechanism comprises at least one movable handle 31 and at least one movable pin 32 'which is mechanically linked to the movement of said handle by virtue of a linkage assembly known per se.

As visible by comparing the figures 1 and 2 , the handle 31 is movable between a locking position, in figure 1 , in which the sash 3 is held against the sash 2 and an unlocking position, by figure 2 , in which the sash 3 is free to open or close with respect to said frame 2.

This explanation is important because it is this movement (and its reverse) that a first device allows to achieve in an electrical manner; For this first device, it is not a question of electrically opening the sash (passage of the figure 2 to the figure 3 ), or closing the sash (reverse movement).

To do this, the window comprises inside a top horizontal cross member of the frame 2, a first device 10 for electrically locking and unlocking the window, illustrated in figures 4 to 9 .

This device 10 comprises a casing 11 which houses an electric motor 12 and further comprises an arm 15 which emerges from this casing 11 and which is movable in translation by virtue of said electric motor 12 in a general direction of translation D.

The arm 15 can be attached to the sash 3 and detachable from the sash thanks to a hook 16 located on the arm 15, this hook being able to push or pull depending on the direction general translation DG a pin 32 of the opening 3 which is mechanically linked to the movement of the handle 31 through the linkage assembly.

During electrical locking and unlocking, the arm 15 is attached to the pin 32 of the leaf 3 by means of the hook 16.

The drive movement of the arm 15 by the motor will be described later.

The figure 4 illustrates the operation of the device 10 when the electric unlocking-locking is implemented; this implementation takes place in six states, numbered 1 to 5 in dotted boxes, to then return to state 1.

The figure 5 illustrates the operation of the device 10 when the manual unlocking-locking is implemented; this implementation takes place in five states, numbered 1, 2 ', 3' and 4 'in dotted boxes, to then return to state 1.

• l'état 1 correspond ainsi à l'état de la figure 1, fenêtre fermée et verrouillée
• les états 2 et 2' correspondent à l'état de la figure 2, fenêtre fermée mais déverrouillée, et
• les états 3 et 3' correspondent à l'état de la figure 3, fenêtre ouverte (et déverrouillée).

In these two figures,

• state 1 thus corresponds to the state of the figure 1 , window closed and locked
• states 2 and 2 'correspond to the state of the figure 2 , window closed but unlocked, and
• states 3 and 3 'correspond to the state of the figure 3 , window open (and unlocked).

State 1 thus corresponds to a traditional state where the handle 31 is in the extension of a vertical cross member of the leaf 3, as visible in figure 1 .

The passage from state 1 to state 2 or to state 2 'thus corresponds to the opening of the handle 31, here in a rotational movement of 90 ° along a horizontal axis, from the bottom to the right, seen from the inside: this is the unlocking stage.

In state 2 or 2 ', the sash is free to open: it opens under the effect of a wind directed from the outside to the inside and / or under the effect of minus a seal present, as usual, between the sash and the frame.

State 3 or 3 ′ illustrates the pin 32, free: the leaf 3 can be manipulated "à la française", manually, by rotation around the vertical axis Rv; in this state, the pin 32 can be more or less distant from the device 10, depending on the degree of opening of the leaf.

In state 4 or 4 'the sash 3 has been closed in such a way that it is pressed against the frame 2, despite the presence of the seal (s): this state is not reached by an adequate human thrust; as explained previously, the device 10 does not intervene in the opening and closing of the leaf literally; he only intervenes in the unlocking-locking of the opening vis-à-vis the frame when it is energized and electrically controlled.

As visible in figure 5 , the arm 15 is stationary in states 1, 2 ', 3', 4 'and 1, as well as in the intermediate stages between these states, when the device 10 is not energized and is not electrically controlled.

The two figures 4 and 5 have in common the horizontal stroke c of the pin 32: this stroke corresponds to the horizontal displacement of this pin when unlocking the handle 31 (electrically from state 1 to state 2; manually from state 1 to 'state 2') and when locking the handle 31 (electrically from state 4 to state 5; manually from state 4 'to state 1).

• de son état de la figure 1 à celui de la figure 2 lors du déverrouillage électrique, et
• de son état de la figure 2 à celui de la figure 1 lors du verrouillage électrique. Comme visible en figure 4, le bras 15 du dispositif 10 comporte :
• d'une part un crochet 16 présentant une ouverture 17 orientée vers ledit ouvrant 3, et plus précisément orientée vers le pion 32 lorsque l'ouvrant est fermé, que la poignée soit verrouillée ou non, et
• d'autre part une languette 20 qui est liée mécaniquement au bras 15 et qui s'étend au-dessus d'une partie seulement de l'ouverture 17 du crochet 16, afin que pour le verrouillage électrique de la poignée, ledit pion 32 passe sous ladite languette 20 lors de la fermeture de l'ouvrant 3 contre le dormant 2 (correspondant à l'étape de l'état 3 à l'état 4) par déformation élastique de la languette et retienne le pion 32 pour empêcher l'ouverture de l'ouvrant 3 (maintien de l'état 4) jusqu'au verrouillage électrique par translation du bras 15 grâce au moteur électrique 12.

Although this is not illustrated, it is easy to understand that the unlocking and the electric locking can be seen from the inside since the handle 31 moves:

• of his state of figure 1 to that of the figure 2 when unlocking electrically, and
• of his state of figure 2 to that of the figure 1 when electrically locking. As visible in figure 4 , the arm 15 of the device 10 comprises:
• on the one hand a hook 16 having an opening 17 oriented towards said opening 3, and more precisely oriented towards the pin 32 when the opening is closed, whether the handle is locked or not, and
• on the other hand a tongue 20 which is mechanically linked to the arm 15 and which extends above only a part of the opening 17 of the hook 16, so that for the electrical locking of the handle, said pin 32 passes under said tongue 20 when closing the opening 3 against the frame 2 (corresponding to the step from state 3 to state 4) by elastic deformation of the tongue and retains the pin 32 to prevent opening from the leaf 3 (maintaining state 4) to the electric locking by translation of the arm 15 using the electric motor 12.

The opening 17 of the hook 16 is thus intended to accommodate the pin 32 of the opening when unlocking-locking the handle 31.

This pawn 32, unlike the pawn 32 'visible in figure 3 , is not a pin which cooperates with a specific cavity formed in the frame of the frame 2; it only cooperates with the hook 16 of the arm 15.

State 1 of device 10 is illustrated in figure 6 . For the device, it is an idle state, window closed and locked, pending an unlocking instruction.

As visible in this figure, the translation of the arm 15 in the general direction DG under the housing 11 is facilitated by the presence, on the arm 15, of a pin 39 which can slide inside a guide slot 19. made on the underside of the housing 11.

From this state, the unlocking of the pin 32, and consequently of the handle 31, takes place by translating the arm 15 to the left, as indicated by state 2 in figure 4 . In this state, the sash is unlocked and free to open.

Status 3 of the device is shown in figures 7 and 8 : these figures show that the opening 17 of the hook 16 is arranged opposite the pin 32 while waiting for the opening to be pushed against the frame: this step allows the pin 32 to lift the tab 20 and to pass under the tongue 20 by elastic deformation of the tongue; it is the passage of the figure 8 to the figure 9 .

Status 4 of the device is shown in figure 9 .

To allow this passage, the tongue 20 is made for example from a stainless steel plate, deformed by stamping and then preferably has a thickness of less than 3 mm and in particular of the order of 1 mm.

The tongue 20 is linked to the arm 15, for example by crimping.

The arm 15 and its hook are preferably integral.

The arm 15 and its hook can be made from a single steel plate, but they are then thicker than the tongue because they must be more rigid than the tongue. The fact that the arm and the hook are flat makes it possible to limit the bulk.

The figure 5 clearly shows that during the manual unlocking-locking of the handle 31, the pin 32 does not cooperate with the hook 16 and the arm 15 is stationary.

The figures 4 and 5 show moreover that the part of the opening 17 which is not covered by the tongue 20 has a width corresponding to the stroke c of the pin 32 during the locking-unlocking of the handle 31, whether this locking-unlocking is electric as in figure 4 , or manual as in figure 5 . This stroke can be for example 20 or 30 mm.

As visible in figure 8 , the tongue 20 has a length L ₂₀ substantially identical to the length L ₃₂ of the pin 32.

In the present exemplary embodiment, the pin 32 has a flared head 34 and the tongue 20 has a return 21 at an end opposite to its connection with said arm to retain said head 34. Said return 21 has a V-shape open towards the bottom. casing 11 so that a wing of the V constitutes a bearing face which facilitates the lifting of the tongue 20 when the head 34 of the pin 32 bears against this wing.

The device 10 furthermore preferably comprises a presence sensor 23 for detecting the presence of said pin 32 under said tab 20 and triggering the electrical locking.

For this, the tab 20 has a hole 22: the optical signal emitted by the presence sensor 23 can thus detect the presence of the pin 32 through this hole 22.

The hook 16 is located at one end of the arm 15; at the other end of the arm 15, the latter is mechanically linked to the electric motor 12 by a fastening element 18.

The electric motor 12 drives in rotation a worm 13 having an axis Ad and mechanically connected to the arm 15 by the fixing element 18, the arm 15 being movable in the general direction DG which is here parallel horizontally and vertically with the axis Ad.

As visible in figures 6 and 7 , the device 10 is particularly compact: the rotation of the electric motor 12 is first transmitted to a first motor pinion 12 ', arranged coaxially with the motor, then to a second motor pinion 12 "placed under the first, while being offset laterally, and finally to a screw pinion 25, which drives the worm 13 in rotation and thus allows the translation of the arm 15.

To figures 6 and 7 the electric motor 12 is placed above the worm 13 so that the device 10 is more compact; however, it is possible that the worm is in continuity with the axis of the electric motor, with a worm axis exactly aligned with that of the electric motor or offset by a few millimeters, or even that the electric motor is placed next to the worm, on the same horizontal plane or on a very close horizontal plane.

As visible on the figure 4 , if the device 10 is no longer electrically powered while the window is open (state 3), then it suffices to push the sash 3 against the frame 2 (state 4) and manually actuate the handle 31, c 'that is to say to place the window in the closed and locked position by going through state 4 then returning to state 1.

Thus, it is not necessary to provide a particular release system for the device 10. It is sufficient just to provide, for good order of operation, that when subsequent power supply to device 10, that initiates a reset cycle so that arm 15 returns to state 1.

It is important that the electric motors used for electric locking-unlocking applications are generally motors which cannot withstand being driven in “no-load” rotation, that is to say without a power supply.

However, it is possible to provide a mechanical disengagement system 24 of the engagement between the electric motor 12 and the worm 13.

The figures 10a and 10b illustrate a disengagement system 24 which is located, mechanically, between the electric motor 12 and the worm 13 in order to allow free rotation of the worm 13 and therefore free movement of the arm 15 without rotation of the electric motor 12.

This release system 24 comprises a screw pinion 25 which is located along the axis Ab of the worm 13, mechanically secured to this worm, that is to say that any rotation of the worm causes the rotation of this screw pinion 25 and vice versa.

The screw pinion 25 is serrated in a centripetal manner and is mounted on a hub 26, coaxially with the latter; the screw pinion 25 can move longitudinally along the axis of the hub 26 but remains in mechanical engagement with the hub 26 thanks to a draft-undercut system: for example, the hub 26 can have on its outer face a flat and the screw pinion 25 a similar and reverse female shape allowing the latter to slide longitudinally along the hub 26, here inside the hub 26.

However, the teeth of the screw pinion 25 do not touch the worm 13 and the screw pinion 25 is maintained, in normal driving operation at a non-zero distance dp from a proximal end of said worm 13 below. the effect of a clutch spring 27 interposed between the worm 13 and the screw pinion 25. The clutch spring 27 is coaxial with the hub 26.

To operate the clutch, it is then sufficient to modify this distance dp, here by pressing from the right to the left to compress the clutch spring 27 even more and release the screw pinion 25 from the direct or indirect engagement (via other pinion (s) 12 ', 12 ") of the electric motor 12.

This support is notch because means are provided to enable this even more compressed position of the release spring 27 to be blocked-stopped.

The spring 27 is thus compressed between the proximal end of the worm 13 and the screw pinion 25, the screw pinion 25 comprising a ring 28, coaxial with said screw pinion 25 and of a diameter smaller than the pinion of screw 25, in order to allow screw pinion 25 to rotate without driving the second 12 "motor pinion.

To push on the screw pinion 25, a support washer 25 'is provided: its diameter is larger than that of the ring 28 but smaller than that of the screw pinion 25 so as not to touch the second motor pinion 12 ".

The stopper support thus comprises here a pin 29, having the general shape of a U, with the wings of the U twisted transversely to the general direction of the U, said pin being movable in rotation about a horizontal axis located at the inside the casing 11 and the base of the U emerging from the casing 11 through a hole 14 located on the underside of the casing 11, said pin 29 having a shape enabling the ring 28 to be pressed in order to compress the release spring 27 and the hole 14 comprising a notch 14 'to enable this support to be blocked.

The pin touches on one side, or preferably on both sides, the bearing washer 25 ', without contact with the ring 28.

Thus, the pin 29 is accessible from the gap between the frame and the opening, in order to allow the worm screw of the electric motor to be disengaged by pressing on the support washer 25 'and to allow the worm to be able to disengage it. rotate without movement of the electric motor and without movement of the rest of the mechanical drive mechanically linked to the electric motor.

The release system 24 was presented above in connection with the opening "à la française", illustrated in figures 1 to 3 and the device 10 for electric unlocking-unlocking of the handle illustrated in figures 4 to 9 However, this release system is applicable to any type of electric unlocking-unlocking device using an electric motor and a worm.

The release system 24 is applicable in particular to a second device 10 ′ for double electric unlocking-unlocking and electric opening-closing of a “tilt-and-turn” or “oscillating” window, as presented below with reference to figures 11 to 31 and partially visible on the figures 22 to 31 .

In this configuration, the electric motor 12 drives in rotation a worm 13 having an axis Ad and mechanically connected to a mobile arm 45.

During the electric locking and unlocking, the arm 45 is attached to a pin 72 of the leaf 3, similar to the pin 32, thanks to a means 46 'for attaching-detaching an element (the pin 72) from the leaf 3 .

The figures 11 to 13 illustrate the swinging opening movement of a shutter 1 'which is here an “oscillating” or “tilt and turn” window, respectively in the closed window position with the locked handle, in the closed window position with the unlocked handle and in the open window position, in a manner similar to figures 1 to 3 for a window opening “à la française”.

The window of figures 11 to 13 is identical to that of figures 1 to 3 in that it comprises a fixed frame, or "frame 2", as well as an opening 3 which is movable relative to the frame; however, in the case of figures 11 to 13 , mobility is along an axis of rotation Rh, which is in the case of the oscillating opening, a horizontal axis of rotation.

On the figures 11 to 13 , the window is positioned inclined in order to better visualize the movement of the sash relative to the frame, but in reality, the window is intended to be positioned vertically and the axis of rotation Rh is thus horizontal.

The opening 3 also includes a locking-unlocking mechanism 30 which is located against a vertical edge of the opening. This mechanism also comprises at least one movable handle 31 and at least one movable pin 32 ', which is mechanically linked to the movement of said handle by virtue of a linkage assembly known per se.

As visible by comparing the figures 11 and 12 , the handle 31 is movable between a locking position, in figure 1 , in which the sash 3 is held against the sash 2 and an unlocking position, in figure 12 , in which the sash 3 is free to open or close with respect to said frame 2.

This explanation is important because it is this movement (and its reverse) that the device 10 ′ enables to be carried out electrically; however, in the case of the device 10 ′, it is also a question of electrically opening the opening (passage of the figure 12 to the figure 13 ), or the closing of the leaf (reverse movement) but only for an oscillating movement with respect to the horizontal axis of rotation Rh.

To do this, the window comprises inside a top horizontal cross member of the frame 2, a device 10 'for electrically locking and unlocking the window and for opening and closing the window, illustrated in figures 14 to 31 .

This device 10 ', different from the device 10, comprises a casing 11', different from the casing 11 of the figures 6 to 9 , but which houses in a manner similar to the casing 11 an electric motor 12 and further comprises an arm 45 which comes out of this casing 11 'and one end of which is movable in translation with respect to the casing 11' thanks to the electric motor 12 according to a general direction of translation D. The driving movement of the arm 45 by the motor will be described below.

The figure 14 illustrates the operation of the device 10 'when the electric unlocking-locking and the electric opening-closing are implemented; this implementation takes place in six states, numbered 11 to 15 in dotted boxes, to then return to state 11.

The figure 15 illustrates the operation of the device 10 'when the manual unlocking-locking and manual opening-closing are implemented; this implementation takes place in three states, numbered 11, 12 ', in dotted boxes, to then return to state 11.

• l'état 11 correspond ainsi à l'état de la figure 11, fenêtre fermée et verrouillée
• les états 12 et 12' correspondent à l'état de la figure 12, fenêtre fermée mais déverrouillée, et
• les états 13 et 13' correspondent à l'état de la figure 13, fenêtre ouverte (et déverrouillée).

In these two figures,

• state 11 thus corresponds to the state of the figure 11 , window closed and locked
• states 12 and 12 'correspond to the state of the figure 12 , window closed but unlocked, and
• states 13 and 13 'correspond to the state of the figure 13 , window open (and unlocked).

State 11 thus corresponds to a traditional state where the handle 31 is in the extension of a vertical cross member of the leaf 3.

The passage from state 11 to state 12 or to state 12 'thus corresponds to the opening of the handle 31, here in a rotational movement of 90 ° along a horizontal axis, from the bottom to the right, seen from the inside: this is the unlocking stage.

In state 12 or 12 ', the sash is openable: it opens either under the effect of either the electric motor or manual traction on the sash.

In state 12 ', the pin 72 is free: the leaf 3 can be manipulated manually, by rotation around the horizontal axis Rh; in this state, the pin 72 can be more or less distant from the device 10 ', depending on the degree of opening of the opening.

State 13 illustrates the pin 72 on the point of moving away from the frame under the effect of the thrust of a compass 44, illustrated at the bottom right of the figure 14 .

In state 14, the sash 3 is pushed by the compass 44 to open by rotation along the horizontal axis of rotation Rh.

In state 15, the sash 3 is open to the maximum according to what is allowed by the compass 44.

In states 13 to 15, the pin 72 remains firmly attached to the compass thanks to a means 46 'for attaching / detaching an element of said opening 3, illustrated here by a lock 46 described below.

As explained previously, the device 10 ′ intervenes for the electric opening and closing of the leaf literally in addition to intervening for the electric unlocking-locking of the leaf vis-à-vis the frame.

As visible in figure 15 , the arm 45 is stationary in states 11, 12 ', and 11, as well as in the intermediate stages between these states.

• de son état de la figure 11 à celui de la figure 12 lors du déverrouillage électrique (états 11 à 13), et
• de son état de la figure 12 à celui de la figure 11 lors du verrouillage électrique (états 13 à 11).

Although this is not illustrated, it is easy to understand that the unlocking and the electric locking can be seen from the inside since the handle 31 moves:

• of his state of figure 11 to that of the figure 12 during electrical unlocking (states 11 to 13), and
• of his state of figure 12 to that of the figure 11 during electrical locking (states 13 to 11).

The device 10 'comprises a means 46' for attaching / detaching an element of the opening 3 which is particular.

• un anneau 47 qui est fermé sur lui-même et qui présente un trou 48 rond débouchant sur une face inférieure 49 et sur une face supérieure 50,
• un axe de rotation Av horizontal situé entre ces deux faces et à côté du trou 48
• au moins une aile 51, située de l'autre côté de l'anneau 47 par rapport audit axe de rotation Rv, et
• au moins un aimant 52, et de préférence deux aimants 52,52' situé(s) en face inférieure 49 et réalisant une force de retenue de l'anneau contre le bras 45.

It is thus provided that the arm 45 comprises a lock 46, visible in figure 16 , presenting:

• a ring 47 which is closed on itself and which has a round hole 48 opening out on a lower face 49 and on an upper face 50,
• a horizontal axis of rotation Av located between these two faces and next to the hole 48
• at least one wing 51, located on the other side of the ring 47 with respect to said axis of rotation Rv, and
• at least one magnet 52, and preferably two magnets 52, 52 ′ located on the lower face 49 and providing a force for retaining the ring against the arm 45.

The wing 51 has a lower face 53 which is bevelled towards an upper face 54 of the wing (that is to say which is not in the extension of the face bottom of the ring) so that a horizontal translation towards the rear of the latch 46 causes the rotation of said latch about its axis Av against the retaining force of the magnet 52, by sliding of the wing 51 on a stop 63 independent of the arm 45 and that the pin 72 can enter the hole 48 or be extracted therefrom.

This pawn 72, unlike the pawn 32 'visible in figure 13 , is not a pin which cooperates with a specific cavity formed in the frame of the frame 2; it only cooperates with the latch 46 of the arm 45.

The inner section of hole 48 must be larger than the outer section of pin 72 from the top of the pin to allow the pin to enter the hole.

For example, the hole 48 may be circular and the pin 72 may be cylindrical and the inside diameter of the hole 48 is greater than the outside diameter of the pin.

In the present exemplary embodiment, the pin 72 has a flared head 74 in the form of a circular crown and the diameter D ₇₄ of the head is less than the diameter D ₄₈ of the hole 48. D ₄₈ may for example be 12 mm and D _74. may for example be 11 mm.

The pin 72 also comprises under its head 74 a foot 75, thinner than the head and a base 76 longer and wider than the head, which serves to fix the pin 72 to the linkage assembly of the opening. The thickness of the trunk 75 corresponds substantially to the thickness of the arm 45.

Thus, the sliding of the wing 51 on the stop 63 independent of the arm 45 allows more than the head 74 of the pin can penetrate into the hole 48 or be extracted therefrom.

The lock 46 is made for example from a machined steel plate and then preferably has an overall thickness of the order of 6 mm.

The arm 45 can be made from a steel plate, but it does not need to be as thick as the latch.

In the version illustrated here, the latch 46 has two wings 51.51 'located on the other side of the ring 47 with respect to the axis of rotation Rv and which are separated from each other with a space empty between it, each wing 51, 51 'sliding on a stop 63, 63' independent of the arm 45 so that the pin 72 (and more precisely the head 74 of the pin) can enter the hole 48 or be extracted therefrom, as visible to figures 22 to 27 . Thus, thanks to this double sliding, the friction forces between each wing and each stopper are halved and the reliability of the device 10 'is increased.

As visible on the figures 18 to 21 , a horizontal translation towards the rear (towards the left in these figures) causes the tensioning of an attenuating spring 43 and a translation towards the front is carried out to generate the return of the lower face 49 against the arm 45 under the effect of the retaining force of the magnets, this force being attenuated by the release of the attenuation spring 43. Thus the noises of the latch 46 slamming against the arm 45 are attenuated and wear premature of these parts is avoided.

The upper face 50 and the lower face 49 of the ring 47 are bevelled, said ring being thicker near the axis of rotation Rv, in order to increase the mechanical strength of the lock.

The arm 45 ends under the latch 46 in a flat U-shape whose opening is at least as wide as the width of the hole 48 and whose branches of the U are located opposite the two magnets 52,52 'lock 46.

The housing 11 'comprises at least one stop 63, 63', and preferably two stops 63, 63 'which has (each) a rounded shape downwards in order to allow the opening and closing of the latch 46 by sliding d 'a wing 51, 51' and preferably each wing 51, 51 '.

• un bras 45 dont une extrémité est entrainée en translation par rapport au carter 11' par le moteur électrique 12 tout en étant mobile en rotation par rapport à un axe vertical Rb et dont une autre extrémité comporte un moyen 46' pour attacher-détacher un élément dudit ouvrant 3 et en particulier un verrou 46 pour attacher-détacher le pion 72,
• une cane 55 dont une extrémité est mobile en rotation selon un axe vertical Rd par rapport à un point du bras 45 situé entre les deux extrémités du bras 45 et dont une autre extrémité est mobile en translation horizontale par rapport audit carter 11' tout en étant mobile en rotation selon un axe de rotation vertical Rc par rapport au carter 11'.

In the device 10 ′, the closing and the oscillating opening of the leaf 3 are carried out using a compass system 44 comprising:

• an arm 45, one end of which is driven in translation with respect to the casing 11 'by the electric motor 12 while being movable in rotation with respect to a vertical axis Rb and of which another end comprises a means 46' for attaching / detaching an element of said opening 3 and in particular a lock 46 for attaching / detaching the pin 72,
• a cane 55, one end of which is movable in rotation along a vertical axis Rd with respect to a point of the arm 45 located between the two ends of the arm 45 and of which another end is movable in horizontal translation with respect to said casing 11 'while being movable in rotation along a vertical axis of rotation Rc relative to the housing 11 '.

• l'axe de rotation Rd de la cane 55 étant guidé en translation horizontale puis en rotation par rapport à la verticale par un guide 60 du carter ayant un élément de guidage est en forme de L arrondi, puis est libre, et
• l'axe de rotation Rc de la cane 55 étant guidé en translation horizontale par un guide droit 61 et une came 62 fixée à ladite cane 55 étant guidée en rotation par rapport à la verticale par une butée 63 du carter 11'.

After having attached the pin 72 to the means 46 '(to the lock 46) the device 10' operates, as can be seen on the figures 28 to 31 , a horizontal translational movement to the left then a rotational movement:

• the axis of rotation Rd of the cane 55 being guided in horizontal translation then in rotation with respect to the vertical by a guide 60 of the housing having a guide element is in the shape of a rounded L, then is free, and
• the axis of rotation Rc of the rod 55 being guided in horizontal translation by a straight guide 61 and a cam 62 fixed to said rod 55 being guided in rotation with respect to the vertical by a stop 63 of the housing 11 '.

The cane 55 can be made from a steel plate and can be of the same thickness as the arm 45. The fact that the arm 45 and the cane 55 are flat makes it possible to limit the bulk.

As visible in particular on figures 29 and 31 , the end of the cane 55 which is movable in rotation along a vertical axis Rd relative to a point of the arm 45 is disposed on the arm 45 (and not below) and comprises a cylindrical roller 56 in free rotation and located on the cane 55.

In addition, the end of the rod 55 which is movable in horizontal translation with respect to said casing 11 'while being movable in rotation about a vertical axis of rotation Rc with respect to the casing 11' comprises a cylindrical roller 57 in free rotation located on said cane 55.

The guide 60 having a guide element is in the shape of a rounded L consists of a straight groove arranged in a general direction DG central longitudinal of the casing 11 'and of an angled groove opening onto a longitudinal edge of said casing 11' .

This bent groove can preferably be arranged opening to the left or to the right of the housing: in the application of the device 10 'to a tilt-and-turn window, this allows use that the vertical axis of rotation is to the right. or to the left of the sash.

The straight guide 61 is a groove made in the underside of the casing 11 ', this groove preferably extending in the general central longitudinal direction DG of the casing 11'.

The stop 63 has a rounded shape downwards in order to allow the opening and closing of a means 46 'for attaching / detaching an element (in this case a pin 72) from the opening 3 by sliding a wing 51, 51 ', as described below.

The present invention is described in the above by way of example. It is understood that a person skilled in the art is able to produce different variants of the invention without, however, departing from the scope of the patent as defined by the claims.

For example, the device 10, 10 'can be placed not in a top cross member of the frame, but in a low cross member. In this case, the figures must be reversed to be seen as through a horizontal mirror.

Furthermore, each of the devices 10, 10 'has been described above in a version which can be described as "the most successful", in which it is both an electric locking-unlocking device for a shutter and a device for locking and unlocking a shutter. '' electric opening-closing of this shutter with in addition on the one hand the possibility of manually operating the unlocking and opening when the opening is closed (as visible respectively in figures 5 and 15 ) and on the other hand the possibility of disengaging the device 10, 10 'in order to make it possible to manually close the opening and lock it manually (thanks to the release device illustrated in figures 10 and 10 ' ).

It has already been specified that the disengagement is optional.

Furthermore, by different programming of the devices 10, 10 ', in a so-called “electric locking-unlocking” version of these devices, the possibility of manually operating the unlocking and opening when the door is closed can be blocked. electrically.

Thus, when the device 10 illustrated in figures 1 to 9 is used as an electric locking-unlocking device with electric locking-unlocking and electric opening-closing of a shutter, it is possible to program a different operation so that steps 1 to 5 in figure 4 are identical but that step 5 is not an automatic transition step to step 1; thus, this step 5 can become a step of electrically locking the pin 32 and maintaining this pin in the locked position. In this situation, as the pin 32 is mechanically linked to the locking / unlocking mechanism 30 of the leaf 3, the leaf is blocked in the closed position. To cause the electric unlocking of the opening, and then allow its opening, it is then necessary to electrically control the passage from step 5 to step 1; step 5 becomes an "at rest" position in which the opening is electrically blocked and in which it is not possible to manually operate the opening as illustrated in figure 5 .

Thus, when the device 10 'illustrated in figures 11 to 31 is used as an electric locking-unlocking device with electric locking-unlocking and electric opening-closing of a shutter, it is possible to program a different operation so that steps 11 to 15 in figure 14 are identical but that step 12 is not an automatic transition step to step 13; so, this step 12 can become a step of electrically locking the pin 72 and maintaining this pin in the locked position. In this situation, as the pin 72 is mechanically linked to the locking / unlocking mechanism 30 of the leaf 3, the leaf is blocked in the closed position. To cause the electric unlocking of the opening, and then allow its opening, it is then necessary to electrically control the passage from step 12 to step 13 and continue opening or return to step 11 and authorize use. manual; step 12 becomes an “at rest” position in which the opening is electrically blocked and in which it is not possible to manually operate the opening as illustrated in figure 15 .

In addition to the versions presented above, each of the devices 10, 10 ′ can be used in a so-called “simple” version in which it is simply an electric locking-unlocking device for a shutter and other means are provided for. opening-closing of the shutter (for example a spring system for the automatic closing of the opening).

Each of these simple electric locking-unlocking devices 10, 10 ′ can be installed in the frame of a shutter, the leaf 3 of which comprises a locking / unlocking mechanism 30; however, the presence of the handle 31 (what a person skilled in the art also calls “a crutch”) is then not essential: the locking / unlocking mechanism 30 is then not operable manually; it can only be operated electrically, by the simple electric locking-unlocking devices 10, 10 '.

Thus, when the device 10 illustrated in figures 1 to 9 is used as a simple electric locking-unlocking device, it is possible to program a different operation so that steps 1 to 5 in figure 4 are identical and that step 5 is the step of electrically locking the pin 32 and maintaining this pin in the locked position. In this situation, as the pin 32 is mechanically linked to the locking / unlocking mechanism 30 of the leaf 3, the leaf is blocked in the closed position. To cause the electric unlocking of the opening, it is then necessary to electrically control the passage from step 5 to step 1; step 5 becomes an "at rest" position in which the opening is electrically blocked and in which it is not possible to manually operate the opening as illustrated in figure 5 .

Thus, when the device 10 'illustrated in figures 11 to 31 is used as a simple electric locking-unlocking device, it is possible to program a different operation so that steps 11 and 12 in figure 14 be identical but without steps 13 to 15; thus, this step 12 can become a step of electrically locking the pin 72 and maintaining this pin in the locked position. In this situation, as the pin 72 is mechanically linked to the locking / unlocking mechanism 30 of the leaf 3, the leaf is blocked in the closed position. To cause the electric unlocking of the opening, it is then necessary to electrically control the passage from step 12 to step 11; step 12 becomes an “at rest” position in which the opening is electrically blocked and in which it is not possible to manually operate the opening as illustrated in figure 15 .

In this simple electric locking-unlocking application with the latch 46, the latch is located at the end of an arm similar to the arm 15 of the device 10. The latch 46 then constitutes an alternative to the hook 16.

The electrical locking-unlocking thus described is applicable to any type of shutter. Each locking-unlocking device 10, 10 ′ uses a pin 32, 72 which is mechanically linked to the locking / unlocking mechanism 30 with linkage of the leaf 3 and which is driven by a locking-unlocking movement by horizontal translation or vertical.
