Description

The invention relates to a drive device for a system of

  double-leaf closure, without central mullion, one of said leaves, said first leaf, comprising a bathe which is designed capable of coming to overlap the other wing, said

  second leaf, in the closed position in the same alignment.

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

  Many manual or motorized drive devices are already known for controlling the opening of a double-leaf closing system, such as the leaves of a gate or flaps.

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

  It should be noted, in fact, that in the context of these two-leaf closing systems without central mullion, one of these wings, said first leaf, comprises a designed pan adapted to come to recovery of the other leaf, said second flap, 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 leaf 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, with regard to 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, of course, drive devices comprising a single drive means for the simultaneous control of two leaves of a closure system.

  However, in this case, these two flaps are necessarily subjected to perfectly synchronized movements, without opening delay of one of the leaves relative to the other, solution not allowing the recovery of the joint plane between these flaps at through a pan.

  Thus, in the context of these drive devices with synchronized operation of two leaves, it is for example known chain drive mechanisms or belt cooperating with gears or pulleys mounted on the axis of rotation of these leaves, the translational control of said chain or belt being provided by appropriate motor means, which may again be of the electric type and / or pneumatic and / or hydraulic.

  Thus, it is for example known from the document FR-2.754.009, such a training device for folding door accordion.

  In short, the individual control of two leaves of a closure system was possible, until now, only through training devices equipping, individually, each of these leaves.

  The present invention proposes to provide a solution to this problem through a drive device comprising a single manual or motorized drive means designed able to control the opening or closing of the two leaves of a system. closing, respecting a pre-established order. Furthermore, advantageously, these drive means are designed to give these flaps of the closure system an identical pivot angle during each opening and closing maneuvers.

  The advantages that flow from the present invention consist, essentially, in that comprising only one manual or motorized drive means, the drive device according to the invention is necessarily a cost less cost compared to multiple drive devices hitherto necessary to ensure the opening or closing, for example, two flaps, a window, door or the like.

  Furthermore, the use of such a single manual or motorized drive means avoids control errors in the opening and closing of these closure systems. Indeed, in the context of the solutions proposed in the state of the art, a malfunction of the drive means of a leaf could lead to poor management of the order of opening and / or closing of these leaves This could have serious consequences for the closure system itself, or even for securing a building. For example, by not respecting the closing order, the shutters of a window can remain partially open facilitating a possible break-in of the building.

  Thus, the invention relates to a drive device for closing system with two leaves without central mullion, one of said leaves, said first leaf, comprising a designed pan adapted to come to recovery of the other leaf, said second leaf , in the closed position in the same alignment, characterized in that it comprises means for controlling the rotation of the leaves, comprising transmission means conceived adapted, through a single manual or motorized drive means, to controlling, from the closing position of the leaves, the opening of the first leaf, respectively of the second leaf, before the opening of the second wing, respectively of the first leaf, and to bring back, from the open position of said leaves, the first beating, respectively the second leaf, in its closed position, after the closing of the second leaf, respectively of the first leaf.

  According to another characteristic of the invention, said transmission means are designed able to push the leaves in their open position by communicating to them an identical rotation angle from their closed position.

  According to another particularity of the invention, said transmission means are designed capable of acting, in the initial phase of opening control, directly on the first leaf or, as the case may be, the second leaf and, beyond a first empty race, on, respectively, the second wing or the first wing.

  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 invention, in the initial opening phase and in the final closing phase, the transmission means have a vacuum stroke, depending on the unlocking or locking case, with respect to each of the leaves.

  According to another particularity of the invention, the transmission means are designed to be disengageable with respect to said leaves beyond a determined resistance force.

  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.

  Other objects and advantages of the present invention will become apparent from the following description relating to an exemplary embodiment given by way of indication and not limitation.

  The understanding of this description will be facilitated with reference to the accompanying drawings in which: Figure 1 is a schematic representation and a shutter type double-leaf shutter; - Figure 2 illustrates, schematically and partially, the two wings in the closed position on which acts the drive device by means of articulated arms compasses; it refers to an installation in the upper part; FIG. 3 is a diagrammatic representation seen from above of FIG. 2; Figure 4 is a partial schematic and bottom view of Figure 2 in the initial phase of opening; FIG. 5 is a view similar to FIG. 4 illustrating the transmission means of the driving device beyond a preliminary unlocking control stroke; - Figure 6 is a view similar to Figure 5 showing the transmission means acting on the second flap beyond a first vacuum stroke; - Figure 7 corresponds to a view similar to Figures 4 to 6, the wings being opened; FIG. 8, which is a view similar to FIGS. 4 to 7, and illustrates the transmission means of the drive device during the final opening phase, during which a second idling stroke enables the second leaf to make up the delay related to the first empty race; FIG. 9 illustrates the transmission means at the end of the opening control stroke of the two leaves; - Figure 10 is a schematic and elevational representation of the drive device in the context of Figure 9; 11 shows, schematically and partially, the drive cam of the transmission means, cam through which it is controlled the rotation of the compass arm acting on a leaf; FIG. 12 is a schematic and partial representation of a sectional view of the drive cam in the frame of FIG. 11.

  As shown in Figure 1 of the attached drawing, the present invention relates to the field of closing systems of the type with two leaves, without central mullion, such as shutters for window, door or the like, gate 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.

  In particular, one of these leaves 3, said first leaf, comprises a pan 5 designed capable of overlapping the other leaf 4, said second leaf, this 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 relates more particularly to a drive device 6 applicable to such a closure system 1 with two leaves 3, 4 in the absence of central mullion, this drive device 6 comprising means for controlling rotation 7 of these leaves 3, 4, comprising transmission means 8 designed adapted, through a single manual or motorized drive means 9, to control, from the closed position F of the leaves, as shown in the figures 2 and 3, the opening of the first leaf 3 before the opening of the second leaf 4 and to return, from the opening position of said leaves 3, 4, the first leaf 3 in its closed position, after the closure of the second leaf flying 4.

  Particularly advantageously, these transmission means 8 are designed able to push these leaves 3, 4 in the open position, marked O in Figures 9 and 10, by communicating to these leaves 3, 4 an angle of rotation a identical since their closed position F, visible Figures 1 to 3.

  Said rotation control means 7 comprise, according to an embodiment illustrated in the drawings, a compass arm 10A, 10B for each leaf 3, 4. These are capable of being rotated about an axis 24 at 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.

  In particular, 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 initial opening phase, said transmission means 8 are able to act on the first leaf 3 so that it starts its rotation towards the open position O, they do not lead the second leaf 4 than after running this first empty race. This results in a pivot angle y of the first leaf 3 which results in the disengagement of the pan 5 before the second leaf 4 begins its rotation.

  According to a first embodiment, to allow these transmission means 8 to give the wings 3, 4, on the whole opening control, a rotation of an identical or similar angle, they may be suitable to retransmit 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 y 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 y.

  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 17 which allows the second leaf 4 to catch the first 3 in the final phase of opening, is used, during the closing command, to allow the transmission means 8, to give the second leaf 4 an advance, a rotation angle y sufficient, relative to the first leaf 3, so that it, equipped with the pan 5, closes after closing the second leaf 4. Similarly, when the latter arrives in closing limit stop, the first empty stroke relative to the second leaf 4 allows to continue the drive of the first leaf 3 to ensure its closure.

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

  Particularly, the drive cable 19 described 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 9, here represented in the form of a pneumatic jack and / or hydraulic and / or electric or other.

  According to the invention, on the axis 24 of which is made integral in rotation the end 11 of a compass arm 10A, 10B, is fixedly mounted a cam 25A, 25B with the periphery 26 of which comes to cooperate a finger of drive 27A, 27B rotatably secured to 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 leaf 3, 4, regardless of the direction of rotation communicated to the drive finger 27A, 27B through the pulley 20A, 20B 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 y 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 push it radially against the action of the elastic return means 28. This makes it possible to catch the angular offset y 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 y corresponding to the angular offset that it is desired to obtain at the beginning of opening between the first leaf 3 and the second wing 4, knowing that with respect to this angular offset y the ramps 29, 30 are adapted.

  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 exerts 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 y between the leaves 3, 4, that intervenes the drive of the first leaf 3.

  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 spring restoring force constituting the elastic return means 28, exerting their force radially on the drive finger 27A, 27B, towards said ramps 29, 30.

  In a very particularly advantageous manner, the cam profile 32 provides this empty stroke 17 necessary, initially, for the unlocking control of a locking fitting 18, during the opening control of the leaves 3, 4, just as, at the time of closing, it allows, conversely, to provide a lock control.

  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.

  The advantages deriving from the present invention consist, not only, in that a single manual or motorized drive means is capable of controlling, in a well-defined order, the opening of two leaves of a closure system such that described above, but, in addition, greatly increases the security in this type of application for the control of closure systems.

  In particular, thanks to disengageable transmission means, the drive device according to the invention avoids any risk of accident.

  In addition, as can be seen from the foregoing explanations, the closure system can be equipped with a locking fitting whose locking and unlocking control can be provided by the drive device itself.

  In previously known solutions, the maintenance in the closed position of flaps, such as roller shutters, could be ensured only through the drive means.

  The present invention has therefore provided an advantageous solution to the problem.

  Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. various elements without departing from the scope and spirit of the invention.
