Description

The present invention relates to the field of devices for electrically locking and unlocking a movable panel. The present invention relates more particularly to a device for locking and unlocking a shutter type window, door or French window, said shutter comprising a frame and an opening which is openable "French" or "tilt-and-turn" And which is rotatable relative to the frame at least along an axis of vertical rotation, said device comprising an electric motor and a movable arm with said electric motor, the opening comprising a locking-unlocking mechanism comprising at least a movable handle and a linkage assembly attached to said handle, said handle being movable between a locking position in which the opening is held against the frame and an unlocking position in which the door is free to open or to close relative to the dormant. The prior art discloses from European Patent Application No. EP 1,312,742 an electric locking-unlocking and electrical opening-closing device of a shutter using a compass system. In this document, there is a means for attaching-detaching an element of the sash which is particular, in the form of a hook openable and reclosable under the action of the engine.

The present invention provides a solution to allow to lock-unlock electrically opening a vis-vis of a frame and to allow manually lock-unlock an opening vis-vis of a frame. The present invention further provides a solution to allow manual unlocking of the sash even if the sash has been electrically locked and manually lock the sash even if the sash has been unlocked electrically. Thus, in the latter case, even if the power supply of the device is cut off after the electrical unlocking, it is still possible to manually lock the door.

The present invention thus relates in its broadest sense to a device for locking and unlocking a shutter type window, door or French window, said shutter comprising a frame and an opening which is openable "French" or "tilt and turn" and which is rotatable relative to the frame at least along an axis of vertical rotation, said device comprising an electric motor and a movable arm through said electric motor, the opening comprising a locking mechanism unlocking device comprising at least one movable handle and a linkage assembly attached to said handle, said handle being movable between a locking position in which the opening is held against the frame and an unlocking position in which the door leaf is free of open or close in relation to that frame. According to the invention, said arm comprises firstly a hook having an aperture oriented towards a pin attached to said linkage assembly and movable with said linkage assembly, said opening being intended for receiving said pin when the door is closed and on the other hand a tongue which is mechanically connected to said arm and extends over only a part of said opening, so that for the electrical locking of said handle, said pin passes under said tongue when closing opening it against the frame and retains said pin to prevent the opening of the opening until the electrical lock through said electric motor.

The object of the invention is thus, when the opening is in the closed position against the frame but the handle is unlocked, to maintain the opening against the frame: it is therefore necessary to prevent the opening does not open under the effect of a wind coming from outside or under the effect of the joints which guarantees the windtightness between the opening and the frame.

The tongue thus exerts a holding force on the pin and thus holds the opening in the closed position; however, a manual effort contrary to this effort restrained free the pawn and thus opens the opening. The tongue preferably has a length substantially identical to the length of said pin and the portion of said opening which is not covered by said tongue has a width corresponding to the stroke of said pin during locking-unlocking. Said pin has a flared head and said tongue has a return to an end opposite 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 tongue and triggering the electrical lock. This increases the reliability of the device. The tongue then preferably comprises a hole for the optical detection of the presence of said pin under said tongue. Preferably, the pin is not a pin which cooperates with a specific cavity formed in the frame: it is present specifically to allow the operation of the device 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, to effect a translational movement only in a general direction which is preferably horizontal. Said hook and said arm are preferably made of material and are, preferably, made from an integral metal plate.

The electric locking-unlocking device comprises a casing which is fixed to the frame, which itself is fixed in the bay that the closing must allow to close. 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 the locking-unlocking, a pin is moved with a translation movement in a direction that is parallel to the adjacent amount of the frame while in the lock unlocking, a bolt is driven in a translation movement in a direction that is perpendicular to the adjacent amount of the frame.

The handle to which is connected the pin can be protruding, type "L" and allowing locking-unlocking by rotation along a horizontal axis; it can also be recessed and allow locking-unlocking by translation in a horizontal or vertical direction. The present invention also relates to a shutter of the window, door or French window type, comprising a frame and an opening that is openable "French" or "tilt-and-turn" and which is rotatable relative to the frame at the door. less according to an axis of vertical rotation and further comprising at least one electrical locking and unlocking device according to the invention, or even two electric locking and unlocking devices according to the invention, said device or devices being preferably positioned in a high amount and-or in a low amount of said frame. Advantageously, the present invention thus makes it possible to lock-unlock an opening electrically, but above all it makes it possible to lock the sash manually, even if the sash has been previously electrically unlocked or to lock the sash electrically, even if the sash has been previously unlocked manually. Advantageously, the present invention thus makes it possible to catch the pin attached to the opening to allow the electric lock that the latter has been opened manually or electrically. Advantageously again, the present invention makes it possible to avoid using a specific electric strike that is difficult to install when it is desired to maintain a manual locking-unlocking device. Advantageously, the present invention provides a solution that is reliable, robust and inexpensive to manufacture and use.

In the description which follows, an example of a shutter of the window type is taken; however, the present invention applies to any type of shutter and in particular to a door or a French window. Figures 1 to 3 illustrate the opening movement of a shutter 1 which is here a window "French", the window may itself be simply "French" or "tilt-and-turn", respectively in position locked handle closed window (Figure 1), in unlocked window closed handle position (Figure 2) and in open window position (Figure 3). This window comprises a fixed frame, or "dormant 2", and an opening 3 which is movable relative to the frame along an axis of rotation Rv, which is in the case of the French opening, an axis of rotation vertical. In FIGS. 1 to 3, the window is positioned inclined in order to better visualize the movement of the opening relative to the frame, but in reality, the window is intended to be positioned vertically and the axis of rotation Rv is thus vertical. Throughout the present document, the length is considered horizontally in the left-right direction in Figure 1 and the height is considered vertically, also referring to Figure 1. Considerations of the type "above" or "below" are made in reference to this orientation. 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 mobile pin 32 ', which is mechanically linked to the movement of said handle through a linkage assembly known per se. As can be seen by comparing FIGS. 1 and 2, the handle 31 is movable between a locking position, in FIG. 1, in which the opening 3 is held completely against the frame 2 and an unlocking position, in FIG. 2, in which the opening 3 is free to open or close relative to said frame 2. This explanation is important because it is this movement (and its inverse), a first device can be made in an electrical manner; it is not a question, for this first device to electrically realize the opening of the opening (passage of Figure 2 in Figure 3), or the closure of the opening (reverse movement). To do this, the window comprises inside a high horizontal cross member of the frame 2, a first device 10 for locking and unlocking the window, illustrated in Figures 4 to 9. This device 10 comprises a housing 11 which houses an electric motor 12 and further comprises an arm 15 which comes out of this housing 11 and which is mobile in translation thanks to said electric motor 12 in a general direction of translation D. The arm 15 is attachable to the opening 3 and detachable from the opening through a hook 16 located on the arm 15, this hook can push or pull in the general direction of translation DG a pin 32 of the opening 3 which is mechanically linked to the movement of the handle 31 through the set of linkage. During the locking and the electrical unlocking the arm 15 is attached to the pin 32 of the opening 3 through the hook 16.

The drive movement of the arm 15 by the motor will be described later. FIG. 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 the state 1. Figure 5 illustrates the operation of the device 10 when the unlocking-manual lock is implemented; this implementation takes place in five states, numbered 1, 2 ', 3' and 4 'in dashed boxes, to return then to the state 1. In these two figures, - the state 1 thus corresponds to the state of FIG. 1, closed and locked window - the states 2 and 2 'correspond to the state of FIG. 2, window closed but unlocked, and the states 3 and 3' correspond to the state of FIG. 3, open window (and unlocked). The state 1 thus corresponds to a traditional state where the handle 31 is in the extension of a vertical cross member of the opening 3, as can be seen in FIG.

The transition from state 1 to state 2 or 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 step.

In state 2 or 2 ', the opening 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 less a seal present, as usual, between the opening and the frame. The state 3 or 3 'illustrates the pin 32, free: the opening 3 can be manipulated "French", manually, by rotation about the vertical axis Rv; in this state, the pin 32 may be more or less remote from the device 10, depending on the degree of opening of the opening. In the 4 or 4 'state the opening 3 has been closed so that it is pressed against the frame 2, despite the presence of the joint (s): this state is reached not adequate human thrust; as explained previously, the device 10 does not intervene in the opening and closing of the opening in the proper sense; it intervenes only in the unlocking-locking of the opening vis-à-vis the frame when energized and electrically controlled. As can be seen in FIG. 5, the arm 15 is stationary at the states 1, 2 ', 3', 4 'and 1, as well as at the intermediate stages between these states, when the device 10 is not energized and is not not electrically controlled. The two figures 4 and 5 have in common the stroke c, horizontal, of the pin 32: this stroke corresponds to the horizontal displacement of this pin during the unlocking of the handle 31 (electrically from state 1 to state 2; state 1 at state 2 ') and when locking handle 31 (electrically from state 4 to state 5, manually from state 4' to state 1). Although this is not illustrated, it is easy to understand that the unlocking and the electric lock are seen from the inside since the handle 31 moves: - from its state of Figure 1 to that of Figure 2 during the electric unlocking , and - from its state of Figure 2 to that of Figure 1 during the electrical lock. As can be seen in FIG. 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 door is closed, that the handle is locked or not, and - on the other hand a tab 20 which is mechanically connected to the arm 15 and which extends over only a portion 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 during the closing of the opening 3 against the frame 2 (corresponding to the step of the state 3 to the state 4) by elastic deformation of the tongue and holds the pin 32 to prevent the opening of the opening 3 (maintaining the state 4) to the electrical locking by translation of the arm 15 through the electric motor 12. The opening 17 of the hook 16 is thus intended for home of the pin 32 of the opening when unlocking-locking the 31. This pin 32, unlike the pin 32 'visible in Figure 3, is not a pin which cooperates with a specific cavity in the frame of the frame 2; it cooperates only with the hook 16 of the arm 15. The state 1 of the device 10 is illustrated in Figure 6. For the device, it is a state at rest, window closed and locked, waiting an unlock instruction. As shown in this figure, the translation of the arm 15 in the general direction DG under the casing 11 is facilitated by the presence, on the arm 15, of a pin 39 which can slide inside a guide slot 19 carried out on the lower face of the housing 11. From this state, the unlocking of the pin 32, and consequently of the handle 31, is effected by translation of the arm 15 to the left, as indicated by the state 2 in FIG. 4 In this state, the opening is unlocked and free to open. The state 3 of the device is illustrated in Figures 7 and 8: these figures show that the opening 17 of the hook 16 is disposed vis-à-vis the pin 32 in the expectation that the door is pushed against the frame: this step allows the pin 32 to lift the tongue 20 and pass under the tongue 20 by elastic deformation of the tongue; this is the passage from Figure 8 to Figure 9. The state 4 of the device is illustrated 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 connected 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 space requirement. FIG. 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.

FIGS. 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 locking and unlocking of the handle 31, that this locking unlocking is electric as in Figure 4, or manual as in Figure 5. This race can be for example 20 or 30 mm. As can be seen in FIG. 8, the tongue 20 has a length L20 substantially identical to the length L32 of the pin 32. In the present embodiment, the pin 32 has a flared head 34 and the tongue 20 has a return 21 at an opposite end. at its connection with said arm to retain said head 34. The device 10 further comprises, preferably, a presence sensor 23 for detecting the presence of said pin 32 under said tongue 20 and trigger the electrical lock. For this, the tongue 20 has a hole 22: the optical signal emitted by the presence sensor 23 can thus detect the presence of the pin 32 through the 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 connected to the electric motor 12 by a fixing element 18. The electric motor 12 rotates 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 seen in FIGS. 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 "disposed under the first, while being offset laterally, and finally to a screw pinion 25, which drives the screw endless 13 in rotation and thus allows the translation of the arm 15. In Figures 6 and 7 the electric motor 12 is disposed above the worm 13 so that the device 10 is more compact; it is possible that the worm is in continuity with the axis of the electric motor, with an axis of worm exactly aligned with that of the electric motor or shifted a few millimeters, or that the electric motor is arranged next to the worm, on the same horizontal plane or on a very close horizontal plane.

As can be seen in FIG. 4, if the device 10 is no longer electrically powered while the window is open (state 3), then all that is necessary is to push the opening 3 against the frame 2 (state 4) and to actuate Manually handle 31, that is to say to place the window in closed and locked position through state 4 and then returning to state 1. Thus, it is not necessary to provide a system of Specific disengagement for the device 10. It is sufficient just to provide, for the correct operating order, that during the subsequent power supply of the device 10, it starts a reset cycle for the arm 15 to return to the state 1.

It is important that the electric motors used for electrical locking-unlocking applications are in general engines which do not support being driven in "idle" rotation, that is to say without power supply. However, it is possible to provide a mechanical release system 24 of the plug between the electric motor 12 and the worm 13.

FIGS. 10a and 10b illustrate a disengaging system 24 which is mechanically located between the electric motor 12 and the worm 13 in order to allow free rotation of the worm 13 and thus free movement of the arm 15 without rotation of the electric motor 12. This clutch system 24 comprises a screw gear 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 gear 25 and vice versa. The screw gear 25 is serrated in a centripetal manner and is mounted on a hub 26, coaxially with the latter; the screw gear 25 can move longitudinally along the axis of the hub 26 but remains mechanically engaged with the hub 26 by means of a draft-undercut system: for example, the hub 26 may have on its outer face a flat surface and the pinion gear 25 a similar and inverse female shape allowing the latter to slide longitudinally along the hub 26.

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

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

This support is notched because means are provided to block-stop this even more compressed position of the disengagement spring 27. The spring 27 is thus compressed between the proximal end of the worm 13 and the pinion screw 25, the screw gear 25 having a ring 28, coaxial with said screw gear 25 and of a smaller diameter than the screw gear 25, to allow the screw gear 25 to rotate without driving the second motor gear 12 " To push on the screw gear 25, a support washer 25 'is provided: its diameter is greater than that of the ring 28 but smaller than that of the screw gear 25 so as not to touch the second motor pinion 12 ". The detent support thus comprises here a pin 29, rotatable about a horizontal axis located inside the housing 11 and out of the housing 11 by a hole 14 located on the underside of the housing 11, said pin 29 having a shape to press the ring 28 to compress the release spring 27 and the hole 14 having a notch 14 'to allow to block the support. The pin touches on one side, or preferably on two sides, the washer 25 ', without contact with the ring 28. Thus, the pin 29 is accessible from the crack between the frame and the opening, in order to to disengage the worm of the electric motor and allow the worm to rotate without movement of the electric motor and without movement of the rest of the mechanical drive mechanically linked to the electric motor. The declutching system 24 has been presented above in connection with the opening "à la française", illustrated in FIGS. 1 to 3 and the device 10 for unlatching and unlocking the handle, illustrated in FIGS. 4 to 9, however, this declutching system is applicable to any type of unlocking device-electric unlocking using an electric motor and a worm. The clutch system 24 is applicable in particular to a second device 10 'for double unlocking and electric unlocking and opening-closing of a "tilt-and-turn" or "oscillating" window, as presented hereinafter with reference to FIGS. 11 to 31 and partially visible in Figures 22 to 31. In this configuration, the electric motor 12 rotates a worm 13 having an axis Ad and mechanically connected to a movable arm 45. During the locking and the electric unlocking, the arm 45 is attached to a pin 72 of the opening 3, similar to the pin 32, by means 46 'for attaching-detaching an element (the pin 72) of the opening 3 .

FIGS. 11 to 13 illustrate the oscillating opening movement of a shutter, which is here an "oscillating" or "tilt-and-turn" window, respectively in a closed handle locked window position, in a closed unlocked handle window position, and in open window position, in a similar manner to Figures 1 to 3 for a window opening "French".

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

In FIGS. 11 to 13, the window is positioned inclined in order to better visualize the movement of the opening 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 comprises 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 means of a linkage assembly known per se. As can be seen by comparing FIGS. 11 and 12, the handle 31 is movable between a locking position, in FIG. 1, in which the opening 3 is held against the frame 2 and an unlocking position, in FIG. opening 3 is free to open or close relative to said frame 2. This explanation is important because it is this movement (and its inverse), the device 10 'allows to achieve an electrical way; however, in the case of the device 10 ', it is also necessary to electrically open the opening of the opening (passage of Figure 12 to Figure 13), or closing the opening (reverse movement) but only for oscillatory movement with respect to the horizontal axis of rotation Rh. To this end, the window comprises, inside an upper horizontal cross member of the frame 2, a device 10 'for locking and unlocking the electric lock. window and opening and closing of the window, illustrated in Figures 14 to 31. This device 10 ', different from the device 10, comprises a housing 11', different from the housing 11, but which houses in a manner similar to the housing 11 an electric motor 12 and further comprises an arm 45 which comes out of this housing 11 and one end of which is movable in translation thanks to the electric motor 12 in a general direction of translation D. The drive movement of the arm 45 by the motor will be described further lo in. FIG. 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 dashed boxes, to return then to the state 11. FIG. 15 illustrates the operation of the device 10 'when the manual unlocking-locking and the opening manual closing are implemented; this implementation takes place in three states, numbered 11, 12 ', in dotted boxes, to return then to the state 11.

In these two figures, the state 11 thus corresponds to the state of FIG. 11, closed and locked window. The states 12 and 12 'correspond to the state of FIG. 12, with the window closed but unlatched, and the states 13 and 13 'correspond to the state of FIG. 13, window open (and unlocked). The state 11 thus corresponds to a traditional state where the handle 31 is in the extension of a vertical cross member of the opening 3. The transition from state 11 to state 12 or state 12 'thus corresponds at 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 step. In the 12 or 12 'state, the opening is openable: it opens under the effect respectively of the electric motor or a manual pull on the opening.

In the state 12 ', the pin 72 is free: the opening 3 can be manipulated manually, by rotation around the horizontal axis Rh; in this state, the pin 72 may be more or less remote from the device 10 ', depending on the degree of opening of the opening. The state 13 illustrates the pin 72 about to move away from the frame under the effect of the thrust of a compass 44, illustrated bottom right of Figure 14. In the state 14 the opening 3 is pushed by the compass 44 to open by rotation along the horizontal axis of rotation Rh. In the state 15, the opening 3 is open to the maximum as permitted by the compass 44.

In states 13 to 15, the pin 72 remains firmly attached to the compass by 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 opening and closing the electric opening in the proper sense in addition to intervene for the electric unlocking-locking of the opening vis-à-vis the frame. As can be seen in FIG. 15, the arm 45 is stationary at the states 11, 12 ', and 11, as well as at the intermediate steps between these states. Although this is not illustrated, it is easy to understand that the unlocking and the electric lock are seen from the inside since the handle 31 moves: - from its state of Figure 11 to that of Figure 12 during the electric unlocking (states 11 to 13), and - from its state of Figure 12 to that of Figure 11 during the electrical lock (states 13 to 11).

The device 10 'comprises a means 46' for attaching-detaching an element of the opening 3 which is particular. It is thus provided that the arm 45 comprises a latch 46, visible in FIG. 16, having: a ring 47 which is closed on itself and which has a round hole 48 opening 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 situated 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 retaining force of the ring against the arm 45. The wing 51 has a lower face 53 which is bevelled in the direction of an upper face 54 of the wing (that is to say which is not in line with the underside 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 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. This pin 72, unlike the pin 32 'visible in Figure 13, is not a pin which cooperates with a specific cavity formed in the frame of the frame 2; it cooperates only with the lock 46 of the arm 45. The inner section of the hole 48 must be greater than the outer section of the pin 72 of 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 larger than the outside diameter of the peg. In the present embodiment, the pin 72 has a flared head 74 in the form of a circular ring and the diameter D74 of the head is smaller than the diameter D48 of the hole 48. D48 can be for example 12 mm and D74 can be for example of 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 secure the pin 72 to the linkage assembly of the opening. The thickness of the trunk 75 substantially corresponds 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 enter the hole 48 or be extract.

The latch 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 lock. In the version illustrated here, the latch 46 comprises two wings 51, 51 'situated on the other side of the ring 47 with respect to the axis of rotation Rv and which are separated from one another 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, as visible Figures 22 to 27.

Thus, thanks to this double sliding, the friction forces between each wing and each stop are reduced by half and the reliability of the device 10 'is increased. As can be seen in FIGS. 18 to 21, a horizontal translation towards the rear (towards the left in these figures) causes the powering up of an attenuation spring 43 and a translation towards the front is made to generate the return. the lower face 49 against the arm 45 under the effect of the magnet retention force, this force being attenuated by the relaxation of the attenuation spring 43. Thus the clacking sounds of the latch 46 against the arm 45 are attenuated and premature wear of these parts is avoided.

The upper face 50 and the lower face 49 of the ring 47 are beveled, said ring being thicker near the axis of rotation Rv, in order to increase the mechanical strength of the lock. The arm 45 terminates under the latch 46 by a flat U-shape whose opening is at least as wide as the width of the hole 48 and whose U-branches are situated opposite the two magnets 52, 52 The housing 11 comprises at least one abutment 63, 63 ', and preferably two abutments 63, 63' each of which has a rounded downward shape to allow the opening and closing of the latch. 46 by sliding a wing 51, 51 'and preferably each wing 51, 51'.

In the device 10 'closing and the oscillating opening of the opening 3 are made using a compass system 44 comprising: - an arm 45 whose end is driven in translation relative to the casing 11 by the electric motor 12 while being rotatable relative to a vertical axis Rb and another end has a means 46 'for attaching-detaching an element of said opening 3 and in particular a latch 46, - a cane 55 whose one end is mobile in rotation along a vertical axis Rd relative to a point of the arm 45 located between the two ends of the arm 45 and whose other end is movable in horizontal translation relative to said housing 11 while being rotatable about an axis of rotation vertical Rc relative to the housing 11. After attaching the pin 72 to the means 46 '(latch 46) the device 10' operates, as shown in Figures 28 to 31, a horizontal translational movement to the g then rotational movement: - the axis of rotation Rd of the rod 55 being guided in horizontal translation and then rotated relative to the vertical by a guide 60 of the casing having a guide element is in the form of 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 relative to the vertical by a stop 63 of the housing 11 The rod 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 can limit the clutter.

As can be seen in particular in FIGS. 29 and 31, the end of the rod 55 which is rotatable about 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 rod 55. In addition, the end of the rod 55 which is movable in horizontal translation relative to said housing 11 while being movable in rotation along a vertical axis of rotation Rc relative to the casing 11 comprises a freely rotating cylindrical roller 57 located on said rod 55. The guide 60 having a rounded L-shaped guide member is constituted by a straight groove disposed in a general longitudinal DG direction of the housing 11 and a bent groove opening on a longitudinal edge of said housing 11. This bent groove may preferably be arranged opening to the left or to the right of the housing: in the application of the device 10 'to a f Being oscillobattante, this allows a use that the vertical axis of rotation is to the right or left of the opening.

The straight guide 61 is a groove formed in the lower face of the casing 11, this groove extending preferably in the general longitudinal DG direction of the casing 11. The stop 63 has a rounded shape downwards to allow opening and closing 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 foregoing by way of example. It is understood that the skilled person is able to achieve different variants of the invention without departing from the scope of the patent as defined by the claims. For example, the device 10, 10 'can be arranged not in a high cross member of the frame, but in a low cross member. In this case, the figures must be reversed to be seen as by a horizontal mirror.
