Description

The invention relates to a drive device for closing system, gate type or the like, comprising at least one leaf, said device comprising means for rotating said leaf, between an open position and a closed position through suitable transmission means.

The present invention will find application in the field of closure systems, more particularly for buildings, such as shutters, doors, gates or the like.

Numerous manual or motorized drive devices are already known for controlling the opening of a single or double leaf closing system, such as the leaves of a gate or swinging shutters.

In particular, these drive devices, whether manual or motorized, are individualized at each leaf. In other words, each of these wings has its own training device, to manage individually, their opening.

It should be noted that for closing systems with two leaves without central mullion, one of these leaves, said first leaf, comprises a designed pan adapted to come to overlap the other leaf, said second leaf, this when they are in the closed position in the same alignment. This batée ensures, thus, the closure of the seal between these two leaves in this closed position.

However, this pan prevents a simultaneous and synchronized operation of the leaves, said first flap equipped with it being obliged to begin its opening maneuver before the second wing is driven. Similarly, when closing, it must be brought into the closed position before the first leaf is pushed into abutment through its bat against the second leaf. However, in the open position, it must be possible to bring each of these wings in support against the facade of the construction. In short, during the closing and opening maneuver, the drive devices are obliged to communicate to these leaves, an identical rotation angle.

It will be noted that for a double-leaf gate closure system, the situation is reversed.

Indeed, the leaves of such a portal are generally intended to open towards the inside of an enclosure, while the batten comes to recovery outwardly of the joint plane between these leaves, when they are closed. In this case, the second flap, not equipped with the pan, necessarily comes first and close last.

When manual control drives are used, compliance with this order is managed by the user himself, while motorized drive devices are necessarily connected to a management unit of their operation. allowing, for example, to delay the opening and closing of one leaf relative to another.

It should be understood that by motorized drive device, one targets as much the electromechanical systems as pneumatic or hydraulic or even combining several of these technologies.

Note, for electromechanical systems, it is, very commonly, a motor that, through a compass arm, acts individually on a flap of the closure system.

For the gates, it is also known engines designed to be housed in structures in the ground so that they can act on the pivot axis of the leaves.

Actuators of the jack type are generally suitable only for gate opening control insofar as they can communicate to a leaf only a limited angle of rotation.

There are drive devices comprising a single drive means for the simultaneous control of two leaves of a closure system. In particular, it is known from document GB-2,087,475 a device comprising, for each leaf, a compass arm controlled in rotation by pulleys driven by a continuous belt or chain system coming to wind on the gear wheel. drive of an engine. On this belt or chain is interposed a spring whose voltage is capable of ensuring a differential stroke of a leaf relative to the other, especially in the final closing phase, where one of the leaves (without pan) closes in first, to authorize the closure of the flap equipped with the batten in recovery of the previous one. This race differential can be provided by a torsion shaft, according to another embodiment described in this document.

Similarly, it is known from FR-2,612,237 a system for remote operation flap shutters comprising a race differential between the two leaves.

In any case, the holding in the closed position of such a flap or gate leaf is ensured through the manual or motorized drive means itself. Thus, this drive means can be designed irreversibly. In other words, a direct action on the leaf does not make it possible to open it. It is also known, in the case a motor drive means, to equip the latter with an electromagnetic brake operating by lack of current. Thus, as soon as the motor is turned off, the activated brake prevents any rotation of the leaf.

In the same principle, maintaining a certain pressure in a pneumatic cylinder and / or hydraulic, it can maintain the closing stop the flap on which it intervenes.

Such holding in the closed position through the only manual or motorized drive means, often provides only relative safety.

Thus, for example, the compass arm, through which a motor drives a flap, is able to ensure that a localized maintenance of the flap, for example in the lower part or in the upper part.

By acting on this shutter opposite to the action of this arm, particularly during an attempted break-in, there is a sufficient lever arm to move it away from its frame and allow the introduction of a tool to force opening.

The problem is of course the same in case of use of a jack of any kind whatsoever.

It is already customary to equip overhead doors of the garage door type with additional locking devices which, in addition to the drive means for controlling the opening and closing of such doors, are able to guarantee their safety against attempted break-ins.

Such additional locking devices are very often in the form of electromechanical systems and consist, for example, in a latch bolt, latch-type latch return latch in the locked position, knowing that an electromagnetic coil or the like is likely, when supplied with current, to control the recoil of this bolt against these means of elastic return.

The locking bolt team frequently opens the door while a keeper arranged on the door frame is designed to cooperate with this bolt.

Thus, during the opening control of the opening, through the motorized drive means which it is equipped, an operation management unit of the drive control means, in order, the unlocking of the or additional locking devices before activating this driving means.

It is understood, of course, that closure systems comprising such additional locking devices are subject to a risk of aggravated dysfunction.

The present invention is intended to respond to the aforementioned problem, this through a drive device for shutter-type closure system, gate or the like, comprising a manual or motorized drive means which is capable, not only , to control the opening and closing of this system, but, moreover, to ensure the locking and unlocking of a locking device type espagnolette bolt or similar which comes to be equipped thereof.

Thus, the invention relates to a drive device for a closure system, such as a shutter, gate or the like, comprising at least one leaf, said device comprising a manual or motorized drive means for controlling said leaf, in rotation, between a opening position and a closed position, through transmission means adapted, characterized in that said transmission means comprise at least one cam with which acts a drive member for the control in rotation of said leaf, the cam or cams being defined in such a way as to provide a vacuum stroke of said means of transmission with respect to said wing, as the case may be, in the initial or final phase of control of the opening or closing of this wing.

The invention will find particular application to closing systems with two leaves without central mullion, one of said leaves, said first leaf, having a designed pan adapted to overlap the other leaf, said second leaf, said transmission means comprising, for each leaf, at least one cam with which is defined able to act a drive member for the control in rotation of said leaf, said cams being angularly offset relative to each other with a angular offset γ, so as to define an empty stroke of said transmission means with respect to the first or second leaf, as appropriate, in the initial or final phase of opening or closing control of these leaves, in order to ensure the opening of the first leaf, respectively of the second leaf, before the opening of the second leaf, respectively of the first leaf, and to bring back, from the open position of said flaps, the first flap, respectively the second flap, in its closed position, after closing the second flap, respectively of the first flap.

Moreover, in the final opening phase, said transmission means have a second idle stroke with respect to the second leaf or the first leaf, respectively, to make up for the phase shift of one relative to the other resulting from the first empty stroke in the initial opening phase.

According to another feature of the drive device, according to the invention, in the initial phase of opening and at the end closing stroke, said driving means is designed capable of executing an additional stroke for unlocking and locking control of a locking device, such as a cremone lock or the like, fitted to said closure system.

Advantageously, the transmission means are of the disengageable type to allow, at the end of the closing stroke of the leaf, the additional idle stroke of the manual or motorized drive means.

The device according to the invention can indifferently be integrated in the lintel or in the threshold, and is in no way limited to one or other of the executions, in the upper part or in the lower part.

As seen in FIG. 1, the present invention relates to the field of closing systems of the shutter type, gate, door or the like.

Thus, in Figure 1 it is more particularly illustrated a closure system 1 in the form of two flaps 3, 4 coming to close, for example, in front of a window of a building.

From now on, it will be observed that the present invention is not limited to such a design. In particular, the invention will also find application in the case of a closure system having only one leaf, the type pivoting about an axis, including vertical.

In particular, one of these leaves 3, said first leaf, comprises a pan 5 designed adapted to overlap the other leaf 4, said second leaf, this when these leaves are pushed in the closed position in the same alignment .

In the usual manner, such flaps 3, 4 are intended to open towards the outside of a building, the presence of the pan 5 on the first leaf 3 imposing the opening thereof before the second leaf 4 .

However, it will be appreciated that the present invention is in no way limited to such a design. For example, in the case of a gate, opening, usually, towards the inside of a chamber, the pan 5 comes, for all that, to close the joint plane between the flaps on the outside of this enclosure.

In this case and if one retains the name above consisting of denominating first flap that equipped with the pan, the opening command occurs in the following order: second flap, then first flap.

Consequently, it should be understood that in the remainder of the description, when an order is specified in the command to open or close one of the leaves relative to the other, the invention also applies. in a situation where a reverse order must be respected.

Thus, the invention more particularly relates to a drive device 6 comprising a manual drive means or motorized 7 for controlling in rotation the flap (s) 3, 4, between an open position O and a closed position F, through transmission means 8. In particular, these comprise at least one cam 25A, 25B ; 25 'with which a drive member 27A, 27B acts; 27 'for the control in rotation of the wing (s) 3, 4, the cam or cams 25A, 25B; 25 'being defined so as to provide a vacuum stroke of said transmission means 8 with respect to said leaves, as the case may be, in the initial or final phase of opening or closing control of this or these leaves 3, 4.

This device according to the invention is of particular interest in the case of a closure system 1 with two leaves 3, 4 in the absence of central mullion. The transmission means 8 are then adapted, through the single manual or motorized drive means 7, to control, from the closed position F of the leaves, as illustrated in FIGS. 2 and 3, the opening of the first leaf 3 before the opening of the second leaf 4 and to bring back, from the opening position of said leaves 3, 4, the first leaf 3 in its closed position, after the closing of the second leaf 4.

Particularly advantageously, these transmission means 8 are designed to push these flaps 3, 4 in the open position, marked O in Figure 9, by communicating an identical rotation angle α from their closed position F , visible Figures 1 to 3.

The driving device 6 comprises, according to the embodiments illustrated in the drawings, a compass arm 10A, 10B for each leaf 3, 4. These can be rotated about an axis 24 to one end 11 by the transmission means 8, while their opposite end 12 cooperates with a slide 13 mounted on the inner side 14 of the wings 3, 4.

According to the invention, said transmission means 8 are designed to act, in the initial phase of opening control beyond a first idle stroke on the second leaf 4. In other words, if, during this phase initial opening, said transmission means 8 are able to act on the first leaf 3 so that it starts its rotation towards the open position 0, they cause the second leaf 4 after have run this first empty race. This results in a pivot angle γ of the first leaf 3 which results in the release of the pan 5 before the second leaf 4 begins its rotation.

According to the configuration, the transmission means 8 are therefore designed capable of acting, in the initial opening control phase, directly on the first leaf 3 or, as the case may be, the second wing 4 and, beyond a first empty stroke on, respectively, the second wing 4 or the first wing 3.

According to a first embodiment, to enable these transmission means 8 to give the wings 3, 4, on the whole opening control, a rotation of an identical angle α or the like, they may be suitable to retransmit to each of these leaves 3, 4, a rotation with a different transmission ratio so that, precisely at the end of opening, the second leaf 4 has caught up with the first leaf 3 of the angle γ resulting from the first empty stroke.

However, according to a second preferred embodiment, in the final opening phase, said transmission means 8 present a second idle stroke relative to, this time, the first leaf 3 allowing the second leaf 4 to catch up the pivot angle γ.

In sum, as the case may be, this second empty stroke relative to the second leaf 4 or to the first leaf 3, respectively, makes it possible to make up for the phase shift of one relative to the other resulting from the first empty stroke. initial phase of opening.

Thus, in the context of an identical transmission ratio, the second idle stroke is at least equal to the first idle stroke.

According to another advantageous feature of the invention, said transmission means 8 are designed capable of acting beyond an initial emptying race 17 for unlocking on the leaves 3, 4, in the initial opening control phase. These transmission means 8 have the same vacuum stroke 17 with respect to these leaves 3, 4 in the final phase of closure to ensure a locking action.

In sum, through this initial and final emptying stroke 17, respectively, of unlocking and locking, the driving device 6, according to the invention, is designed capable of controlling a locking system 18 adapted.

The second empty stroke which allows the second leaf 4 to catch the first 3 in the final opening phase, is used, during the closing command, to allow the transmission means 8 to give the second leaf 4 an advance , a sufficient angle of rotation γ relative to the first leaf 3, so that it, equipped with the pan 5, does not close after closing the second leaf 4. Similarly, when the latter comes to a stop closing end of stroke, the first empty stroke with respect to this second flap 4 allows to continue the drive of the first leaf 3 to ensure its closure.

According to one particularity of the invention, the transmission means 8 are designed to be disengageable with respect to a wing 3, or 4 beyond a determined resistance force.

According to a preferred embodiment, the transmission means 8 are of the drive cable type 19 describing a closed circuit while coming to wind, partially, around two driving pulleys 20A, 20B, each acting on an arm of compass 10A, 10B. This closed circuit can in particular be crossed so as to obtain a reversal of the direction of rotation of the pulleys.

More particularly, the drive cable 19 describes between said pulleys 20A, 20B a forward strand 22 and a return strand 23 on one of which is designed capable of acting the drive means 7, here represented in the form of a jack pneumatic and / or hydraulic and / or electrical or other.

According to a first embodiment visible in FIGS. 4 to 12, on the axis 24 of which the end 11 of a compass arm 10A, 10B is secured in rotation, a cam 25A, 25B is fixedly mounted with the periphery 26 of which comes to cooperate the drive member 27A, 27B in the form of a finger integral in rotation with a pulley 20A, 20B rotatably mounted on the pivot axis 24 of said compass arm 10A, 10B.

Such a drive finger 27A, 27B is mounted radially movable at said pulley 20A, 20B and is subjected to resilient return means 28 designed to push this drive finger 27A, 27B towards the axis 24 against the profile of the cam 25A, 25B.

This comprises at least a first ramp 29 which, under the effect of the radial force exerted by the elastic return means 28, has the consequence of subjecting said cam 25A, 25B, in other words, the axis 24 to a pair in a direction corresponding to the closing of a wing 3, 4, whatever the direction of rotation communicated to the drive finger 27A, 27B through the pulley 20A, 20B on which it depends.

This first ramp 29 is adjacent to at least one second ramp 30 with a reverse effect, that is to say whatever the direction of rotation communicated to the drive finger 27A, 27B through the pulley 20A, 20B, drive finger 27A, 27B exerts on the cam 25A, 25B, under the effect of the radial force of the elastic return means 28, a torque in the opening direction of the corresponding leaf 3, 4.

Thus, if we imagine the drive finger 27A, corresponding to the pulley 20A of the first leaf 3 on the second ramp 30 and that, parallel, the drive finger 27B of the pulley 20B corresponding to the second leaf 4 is, it, on the first ramp 29, the driving of the transmission means 8 in the context of an opening control has the consequence of maintaining the second leaf 4 in the closed position, as long as the drive finger 27B remains the along the first ramp 29, while, for its part, the drive finger 27A, being on the second ramp 30 and exerting, therefore, a torque in the opening direction of the first leaf 3, will have consequently the drive in rotation of the latter in this opening direction.

The cam 25A on the axis 24 of the compass arm 10A corresponding to the first leaf 3 adopts a position symmetrical with respect to the cam 25B on the axis 24 of the compass arm 10B acting on the second leaf 4, with an angular offset γ which corresponds at least the length of the first ramp 29 (in the initial opening phase).

Similarly, in the final opening phase, when the first leaf 3 reaches the opening stop, resulting in the rotational locking of the cam 25A, the drive finger 27A, rotated by the pulley 20A, progresses. along the second ramp 30, the latter coming to repel it radially against the action of the elastic return means 28. This makes it possible to catch the angular offset γ of the cams 25A and 25B. Consequently, this is the second empty stroke of the transmission means 8 with respect to this first leaf 3, knowing that, on the side of the second wing 4, the driving finger 27B exerts, in parallel, a rotation torque on the cam 25B to bring this second flap 4, too, in the fully open position.

Finally, the cams 25A, 25B are angularly offset from the angle γ corresponding to the angular offset that it is desired to obtain at the beginning of opening between the first leaf 3 and the second leaf 4, knowing that with respect to this angular offset γ the ramps 29, 30 are adapted.

In sum, the angular offset γ defines the first and second empty stroke of the transmission means 8 relative to the first 3 or second flap 4, as appropriate, in the initial or final phase of opening control.

As already indicated above, during closing, the second empty stroke of the transmission means 8, allowing the second flapper 4 to catch the first 3 in the final phase of opening, advantageously allows to confer, in the initial phase of closing, the necessary advance to said second flapper 4 relative to the first flapper 3 so that the pan 5 of the latter does not meet the second flap 4 which would prevent the total closure of the flaps.

During this initial closing phase, during this second idle stroke, the drive finger 27A of the arm 10A evolves on the second ramp 30 now on the cam 25A a torque towards the opening of the first leaf 3, while that conversely, the drive finger 27B, at the attack of the first ramp 29 of the cam 25B comes to exert on it a torque in the closing direction of the second leaf 4.

It is only once the drive finger 27A at the bottom of the ramp 30, corresponding to an angular offset γ between the leaves 3, 4, that the drive of the first leaf 3 intervenes.

As can be seen in the drawings and in particular in FIG. 11, the ramps 29, 30 of the cam 25A, 25B are substantially in the extension of one another. They are also framed by cam profiles 31, 32, concentric with the axis of rotation 24 of the latter, and thus compass arms 20A, 20B. In other words, when, for example, in the fully open position of the leaves 3, 4, the driving means 9 continue to drive the transmission means 8, the driving fingers 27A, 27B successively leave the second ramp 30 of their respective cam 25A, 25B to join the cam profile 32 of the latter. This has the effect of annihilating the torque exerted by these drive fingers 27A, 27B on these cams 25A, 25B. This results in the disengagement of the transmission means 8 with respect to the leaves 3, 4.

In similar circumstances when closing the latter, an identical disengagement occurs when the drive fingers 27A, 27B leave the first ramp 29 to join the opposite cam profile 31.

This design still allows such disengagement during operation of the wings 3, 4, especially if one or the other of these comes to meet an obstacle. Note, in this regard, that the user can itself constitute this obstacle by interposing at the level of the trajectory of one or the other flying. The solution according to the invention makes it possible, in the end, to avoid the risks of accident by jamming.

The resistance force to be produced to obtain this clutch is directly dependent on the profile of the ramps 29, 30 and the restoring force of the spring constituting the elastic return means 28, exerting their force radially on the drive finger 27A, 27B, towards said ramps 29, 30.

It should be observed that if in the embodiment described above and shown in the accompanying drawings, the driving fingers 27A, 27B are integral in rotation with the pulleys 20A, 20B, while the axis 24 of the 10A compass arm, 10B fixedly receives the cam 25A, 25B, it is quite possible to imagine an inverted kinematics of equipping the arms 10A, 10B of a drive finger capable of cooperating with a rotating integral cam pulleys.

Figures 13 to 15 correspond to a second embodiment of the invention wherein the cam 25 'is defined by a first disk 101 mounted to rotate with the pivot axis 24 of a compass arm 10A, 10B. In this disc is provided at least one cavity 102 whose bottom 103 is preferably of hemispherical shape fitted to that of a spherical ball 104 defining the drive member 27 '. Moreover, said cavity 102 is designed flared from this bottom 103, to define ramps 29 ', 30' with functions identical to the ramps 29, 30 described with reference to the embodiment referred to above. A second drive disc 105, applied under the impetus of elastic return means 106 on the first disc 101, maintains said ball 104 at the bottom of the cavity 102.

This second drive disc 105 has a cavity 107 preferably of similar shape to that 102 of the first disc 101 so as to accommodate, in part and like the latter, said ball 104. It is also secured in rotation to the pulley 20A, 20B. So when ordering in rotation of this pulley 20A, 20B under the influence of the drive means 7, the rotation of said second disk 105 has the consequence of driving the first disk 101 through the ball 104, precisely because of the axial pressure exerted one on the other. However, in the case of a resistant torque, in one direction of rotation or in the other, provided by the compass arm 10A, 10B, the further control in rotation of the pulley 20A, 20B by the drive means 7 results in the displacement of the ball 104 on one or the other ramp 29 ', 30'. This obviously results in a vacuum stroke of the drive means 7 with respect to said transmission means 8, but also the stressing of the elastic return means 106. Thus, under the influence of a reverse rotation control of said pulley 20A, 20B by the driving means 7, the pressure exerted by the elastic return means 106 through the ball 104 on said ramp 29 ', 30' leads to printing on the first disc 101 a torque in the opposite direction relative to the direction of rotation of the pulley 20A, 20B, this at least until the ball 104 regains the bottom 103 of the cavity 102. In short, a vacuum stroke of the drive means 7, for example in closing end of a leaf 3, 4, results in a new empty stroke of the drive means 7 in the initial phase of opening said leaf 3, 4.

Preferably, the first disc 101 as the second disc 105 are provided with at least three cavities 102 distributed regularly about the axis 24 and each receiving a ball 104.

Furthermore, as can be seen in FIGS. 13 and 14, the cam 25 ', according to this second embodiment, adopts a symmetrical configuration with respect to a plane perpendicular to the axis of rotation 24 of a compass arm 10A, 10B . In other words, on either side of the first disk 101 are formed cavities 102 for the reception of a ball 104 maintained in these last by a second disc 105 and elastic return means 106. This leads to a balance of forces in the pulley 20A, 20B in which advantageously takes position said cam 25 '. It will be noted that the cavities 102 on one side of the disk 101 are angularly offset from those on the opposite side.

As for the elastic return means 106, they consist preferentially by spring washers. The stack composed of these washers 106, disks 105 and the first central disk 101, as visible in FIG. 13, is held under stress between two lateral cheeks 108, 109 of the pulley 20A, 20B.

Note also that as in the first embodiment, it is able to provide a disengagement of the transmission means 8 with respect to the wings 3, 4. In particular, the length of the empty stroke of the means of drive 7 relative to said transmission means is determined by the length of the ramps 29 ', 30' knowing that when the ball 104 comes to leave one or the other of these ramps, it comes to evolve along a track of planar cam 110, in particular at the second disc 105, to which said ball 104 then no longer offers resistance. There is disengagement and this second disk 105 can therefore freely rotate relative to the first 101. Of course, in the symmetrical configuration to which reference has been made above and corresponding to the embodiment shown, the disengagement occurs on both sides of the first record 101.

Particularly advantageously, the cam profile 32 provides the empty stroke 17 necessary, initially, for the unlocking control of a locking fitting 18, when the opening control of the leaves 3, 4, as, at the time of closing, it allows, conversely, to provide a lock control.

In the end, this drive device 6 can be designed such that through this clutch and / or the profile of the cam 25A, 25B; 25 ', the driving means 7 is able, in the initial opening phase and at the end of the closing stroke, to perform the additional stroke 17 for unlocking, respectively locking, control of a locking device. lock 18, in particular a espagnolette bolt, a lock or the like fitted to the closure system.

In sum, by virtue of this additional vacuum stroke 17 or by disengaging the drive means 7 with respect to the leaf which it actuates, this once this leaf is closed, said drive means 7 becomes the driving member of the locking device 18 for controlling the lock knowing that when the opening control of the leaf, the drive means 7 is again involved, as a driving member to act on the locking device 18 to control the unlocking, the clutch with the wing intervening only later.

In particular, the locking device 18 which is equipped with the closure system shown in the accompanying drawings, is in the form of a cremone equipping, on the inner side 170 the amount before 260 of the first leaf 3, that is to say ie the one equipped with the pan 5.

This cremone 18 comprises a rod 270 rotatably mounted by bearings 280 along the front post 260 of the wing 3, said rod 270 carrying at least one locking bolt 290 which, by rotation, is designed to accommodate extend to the rear of a typed 300 of the type equipping the lintel or the threshold of a door, window or the like, and on which come to closing stop the wings 3, 4. In short, after closing the latter by controlling the rotation, in the locking direction, of the rod 270 of the espagnolette 18, the the lock bolts 290 at the rear of this or these typed 300. While ensuring the immobilization in rotation of said rod 270, it ensures a perfect locking of these wings 3, 4, directly at their front uprights. Any attempted break-in will therefore be reflected on the locking device 18 and not on the drive means 7 as was the case in the past.

The espagnolette 18 comprises holding means in the unlocked position as long as the leaf is not folded down on the frame; for example, the espagnolette 18 may be equipped with an elastic return means ensuring the maintenance of the rod 270 in its unlocked position.

Finally, in a design corresponding to the embodiment described above, the drive means 7 are defined suitable, during the additional stroke 8, after disengagement with respect to the leaves 3, 4, to control the rotation of the espagnolette rod 270.

In the context of a cylinder substantially designing the drive means 7, the drive device 6 according to the invention comprises means 310 for converting a linear stroke of the cylinder into a rotary drive.

In particular, these means 310 are constituted, substantially, by a pivoting lever 320, a first end 330 of which is designed to cooperate with a drive pin 340 fitted to the jack for the control in rotation of this lever around its axis. pivoting 350, this during said additional stroke 8. The other end 360 of this lever 320, located on the opposite side relative to the pivot axis 350, comprises attachment means 370 designed to cooperate with means of additional hooking 380 equipping the locking device 18, in this case the espagnolette.

These attachment means 370 are designed capable of cooperating with the complementary hooking means 380 which equip the locking device 18 to push back the locking bolt or bolts 290, as the case may be, in the locked position V or in the unlocked position D under the influence of the drive means 7 during the execution by the latter of the additional idle stroke 17.

Note that if the drive means 7, more particularly the cylinder, must be designed capable of actuating the lever 320 in each of the unlatched locking and unlocking races, the unlocking control itself can be ensured under the impulse. resilient return means 390 designed to pull said lever 320 in the unlocked position knowing that during the execution of the locking stroke by the drive means 7, it acts on the end 330 of said lever 320 through its drive finger 340, against the action of the elastic return means 390. To come more particularly to the attachment means 370 which equip the end 360 of the lever 320, they are constituted by a control finger 400 on which are designed able to come into engagement with the complementary hooking means 380 in the form of a driving fork 410 secured to the espagnolette rod 270.

The cooperation is thus designed so that by rotation of the lever 320 about its axis 350, said control finger 400, engaged in said fork 410, is able to give the rod 270 a rotation between a locking position V , at which point the locking bolt or bolts 290 are positioned at the rear of the corresponding keys 300, and an unlocked position D in which this or these locking bolts 290 are in a position allowing a free rotation of the first leaf 3 and the clearance of the fork 410, thus additional fastening means 380, compared to the means fastening 370 defined by the control finger 400 of the lever 320.

Note, in this connection, that each of the branches 420, 430 of the fork 410 can act, in the manner of cams in cooperation with the control finger 400 to give the cremone rod 270, the desired rotation angle of to reach the locking position V from the unlocked position D and vice versa.

In addition, one of the branches 420 of this fork 410 can be defined, substantially, by a locking bolt 290.

Indeed, insofar as such a bolt is made to cooperate with a tap 300 equipping either the lintel or the threshold of the door or window, the locking bolt takes position, necessarily, at the upper or lower end of the rod rod 270, while the drive device 6, according to the invention, is preferably implanted in a box at the top or bottom of said door or window. It is understood, in these conditions, that it is easy to pass through the control finger 400 of the lever 320, as the case may be, the threshold or lintel to come into cooperation with a locking bolt 290 under the predefined conditions.

It will be noted that the driving means 7 pushing the lever 320 into a position in which it keeps the latching device 18 locked by a permanent action on the locking bolt 290 during the idle locking stroke 8, any risk of Unlocking the shutters 3, 4 is impossible.

Preferably, but not mandatory, the device comprising the drive means 7 is designed to allow a manual opening control of the leaf in case of failure of power supply, or disaster, or other, of preferably from inside the building. Thus the drive means 7, more particularly the jack, may be a reversibly designed mechanism, for example with a manual operating point from inside the building in the form of a lever or an operating knob, or other.

In addition, the locking action may be irreversible.

More particularly, the cam defined by the branch 420 of the fork 410 may be designed so as to oppose, in the locked position V, the control finger 400, a cam track 440 leading to a contact zone 450 with this finger. control 400 which is substantially in the axis of the lever 320, thus creating a jamming.

Thus, by imagining an attempted break-in having the effect of exerting, through the tap 300, a torque in the unlocking direction, on the locking bolt, this torque is reflected through the contact zone 450 of the cam track 440 defined by the branch 420 by an axial thrust on the lever 320. The latter can not pivot under these conditions and keeps perfectly locked the shutters or 3, 4.

It is understood from the above description that the present invention provides a real solution to the problem.
