Description

The present invention relates to the field of devices for opening by a non-manual operation a movable panel only along an axis of rotation and to close the movable panel by a non-manual operation. It is pointed out that the invention does not target locking / unlocking operations, but operations make it possible to release (open) or obstruct (close) a passage without application of human force directly on the mobile panel.

The present invention relates more particularly to the field of double-action opening-closing devices, which can, from the fixed amount, allow opening in one direction or the other with respect to the closed situation.

It may seem obvious if it is desired to be able to open and close a mobile opening in rotation in both directions by non-manual operations to provide that an electric motor can cause this opening to rotate about its axis of rotation in a direction of rotation. opening or closing, and in one direction or the other from the closed position.

When the electric motor acts directly or almost directly on the opening, without lever arm, it is then possible to produce a device integrated in the fixed amount, without visible moving part.

The present invention relates to such an opening-closing device, double action, without lever arm, that is to say to an opening-closing device essentially hidden in a shutter of the shutter .

However, in practice, when an electric motor acts directly or almost directly on an opening, there is a problem of safety because it is preferable to continue to be able to manually operate the opening (opening or closing), especially when the power supply of the motor is not assured; this is particularly important for a fire door, which performs a compartmentalization, in case of fire detection, by automatic closing of the door, while allowing the evacuation of people by manual opening and automatic reclosing.

The present invention thus relates particularly to a non-manual opening-closing device which also allows manual operation, that is to say the application of a human force directly on a mobile opening to allow the opening and closing of a closure.

The prior art knows the US patent US 4,333,270 such a device, in particular by its Figures 11 to 13 . In this variant, an electric motor and a transmission system allow the electric opening of the opening in both directions relative to the axis of rotation of the opening. Closing of the opening is operated by reaction of a single spring directly and as soon as the power supply of the electric motor is cut off.

In this device also, the transmission of the movement between the output of the motor and the axis of rotation of the opening is, essentially, a transmission by cam.

In this device in addition, the motor is always engaged with the mechanical transmission which causes the rotation of the opening. Any manual action on the opening causes a rotation of the output shaft of the motor and this rotation generates, as for any motor, the production by the motor of an electric current, which must be dissipated. The document explains in particular that this production of electric current is managed by a controller to provide dynamic braking by the motor, in order to limit the speed of closure of the sash under the action of the spring.

Finally, the electric motor must be powered all the time waiting between the end of the opening and the beginning of closing.

The prior art also knows the US patent US 3,874,117 an automatic opening-closing device of an opening comprising on the one hand an electric door opener fixed to the frame and comprising an electric motor and a transmission system to allow the electric opening of the opening and secondly a traditional door closer.

In this document, on the one hand the electric motor does not allow the opening of the opening in both directions relative to the axis of rotation because it is indicated that the motor is unidirectional and secondly the closing door is not fixed to the frame but to the opening and it is not double action.

In addition, the output shaft of the door closer is not oriented along the axis of rotation of the opening as there are pivoting arms; the device is not compact and can not be hidden in the frame.

The present invention is based on a solution that uses two different means to achieve on the one hand the opening in one direction or the other from the closed position and on the other hand the closure from one or the other. Another open position, providing that each of these means does not interfere with the other when it is implemented and further providing that each of these means can be disabled to allow to manually operate the movement of the opening .

• une ouverture électrique double action, par un ouvre-porte électrique double action comportant un moteur électrique, et
• une fermeture mécanique à régulation hydraulique double action par un ferme-porte à amortissement hydraulique double action,

et de prévoir en outre, après l'ouverture et avant la fermeture, une désactivation de l'ouvre-porte électrique par mise en oeuvre d'un système d'embrayage électromagnétique. Ce système est mis en oeuvre pour débrayer l'ouvre-porte électrique et l'isoler ainsi mécaniquement du ferme-porte à amortissement hydraulique double action et de l'axe de rotation de l'ouvrant.More specifically, the present invention proposes to provide:

• a double action electric opening, by a double action electric door opener comprising an electric motor, and
• a double action hydraulic mechanical closing mechanism with a double action hydraulic damping door closer

and further provide, after opening and before closing, a deactivation of the electric door opener by implementing an electromagnetic clutch system. This system is implemented to disengage the electric door opener and mechanically isolate the double-acting hydraulic damping door closer and the axis of rotation of the opening.

The present invention thus relates in its broadest sense to an automatic opening-closing device for a shutter of a door or French window, said shutter comprising a frame and at least one opening which is movable in rotation relative to the only depending on an axis of vertical rotation, according to claim 1. The dependent claims present advantageous variants of this device.

Said opening-closing device is remarkable in that it comprises firstly an electric door opener fixed to said frame and comprising an electric motor and a transmission system to allow the electric opening of said door in both directions by relative to the vertical axis of rotation, as well as an electromagnetic clutch system for disengaging said motor relative to the vertical axis of rotation and secondly a double action hydraulic damping door closer fixed to said frame and having an output shaft oriented along said vertical axis of rotation to allow closure of said opening in each direction.

The electric door opener only performs the opening of the opening through the implementation of said electric motor; it does not close the door: it is passive during closing because disengaged from the axis of rotation of the opening by the system clutch; in other words, the electromagnetic clutch system disengages said motor relative to the vertical axis of rotation of the opening at the end of the opening, during all the maintenance of the open sash, throughout the closure of the opening by said double action hydraulic damping door closers and all the time the door is closed.

The door closer only closes the opening through the implementation of a mechanical force operated by a mechanical spring and hydraulic regulation for damping the closure; it does not realize the opening of the opening: it is not its mechanical force that acts directly on the opening during opening to allow this opening.

Thus, when the clutch system is engaged, the electric motor delivers, according to the direction of rotation of its output shaft, an opening rotation, and only opening, to the opening by rotation about its axis. of rotation.

Then, at the end of the opening the clutch system is disengaged, then after a waiting time "open door" the hydraulic damping door closer manages the closing of the opening to its closed position.

The electromagnetic clutch system is particularly advantageous because it allows a precise and quick shutdown of the opening, without risk of drift (or release of the opening) for the duration of the step "open door"; this is an important aspect for the reliability of the device.

The prior art already knows many non-manual closing devices of an opening such as door closers with hydraulic damping.

A hydraulic door closer of the prior art allows to manually open an opening and operates the automatic closure of the opening by controlled movement of a fluid from a sealed chamber to another sealed chamber under the effect of a mechanical spring.

The prior art knows in this respect the French patent application No. FR 2 311 918 or the international patent application N ° WO 2007/135341 to which it is possible to refer for the implementation of said hydraulic damping door closer.

In the context of the invention, preferably, a driving pinion transmits the rotation of said electric motor to a clutch system and then to a reducing system via said transmission system which comprises a moving belt; in this variant, there is preferably no cam between the electric motor and the axis of rotation of the opening. This solution makes it possible to apply a continuously varying torque; this participates in the reliability of the device according to the invention because generates less wear than when cams are used. In addition, the torque varies in a higher range than when cams are used and the opening can be heavier.

Preferably, a reduction system is interposed between the engine of said electric door opener and said axis of rotation of the opening, preferably between said clutch system and said axis of rotation of the opening.

Thus, the motor of said electric door opener is in direct contact with the axis of rotation of the opening leaf, with the interposition of a transmission element, a clutch system and possibly a reduction system, but without use lever arms, to allow for a compact device that can be hidden in an amount.

The transmission system between said electric motor and said clutch system preferably comprises a belt and more preferably still consists of a belt; however, it may comprise a pinion, or even consist of a pinion. A belt is preferred because its operation generates less noise and less friction.

Preferably, said door closer is interposed between said opening and said electric door opener. Thus, the electric opener operates directly the door closer, which is located closer, and a better transmission of efforts is obtained.

In this situation, said door closer preferably comprises a through shaft protruding firstly towards said opening and secondly towards said electric door opener. This traversing shaft is oriented vertically, along the axis of rotation of the opening.

Preferably also, said electric door opener and said door closer are each located in an independent housing, to allow to intervene on one or even change, without changing the other.

In order to increase the compactness of the device, the motor of said electric door opener is preferably located next to said door closer and the clutch system of said electric door opener is located above said door closer.

Said device further comprises, preferably a protection plate to be positioned under said door closer so that the door closer is not accessible.

Said device also preferably comprises an angle sensor for detecting the position of said opening relative to said frame, said angle sensor being preferably located in a housing of said electric door opener.

Said device preferably further comprises for each opening: a high hinge to be hidden in the upper edge of the opening, a low hinge to be hidden in the lower edge of the opening and a thrust collar.

The present invention also relates to a shutter of a building, type door or French window, and in particular a fire door, comprising a frame and at least one opening which is movable in rotation relative to the frame only along an axis vertical rotation and further comprising at least one opening-closing device according to the invention, said device preferably being positioned in a high amount of said frame.

In a particular variant, said closure comprises two openings, and two opening-closing devices are arranged in opposite directions so that the opening direction of the one for an opening is opposite to the opening direction of the opening. other for the other opening and that the closing direction of one is opposite to the closing direction of the other.

Advantageously, the present invention makes it possible to achieve complete automation of the operation of a door, with automation of the opening by the electric door opener and automation of the closing by the door closer.

Advantageously, the present invention allows the device to be used easily for automatic opening and automatic closing by vertical rotation to the left or right (ie "pushing" or "pulling", that is to say "Double action").

Advantageously, especially, the present invention makes it possible to automate the electrical opening and non-electric closing of a fire door, by performing a subdivision in case of fire detection by automatic closing, while allowing the evacuation of persons by manual opening and automatic non-electric reclosing.

It is specified that in these figures the elements in the background are not always represented but that in these figures the proportions between the various elements represented are respected, in order to facilitate reading.

In the description which follows, an example of a door-type shutter is taken; however, the present invention applies to any type of shutter for the passage of people and in particular to a French window.

The figure 1 illustrates a shutter 1 which is here a door "to the French", in half open position; the thick arrow indicates a direction of opening "pulling".

This door comprises a fixed frame, or "dormant 2", and an opening 3 which is movable relative to the frame along an axis of rotation R _v , which is here a vertical axis of rotation. The opening is movable in rotation and solely with respect to this axis R _v . The door is of "double action" type: the opening is movable in both directions of opening relative to the closed position, pulling and pushing.

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

The frame 2 has a high amount 21, a low amount 22, a left amount 23 and a right amount 24; the low amount, as well as the left and right amounts are optional.

• d'une part un ouvre-porte électrique 4 double action, et
• d'autre part un ferme-porte 5 à amortissement hydraulique double action

qui sont tous les deux situés dans le montant haut 21.The high upright 21 comprises an automatic opening-closing device 10 for automatic opening and automatic closing of the opening 3. This device 10 comprises:

• on the one hand a double electric door opener 4, and
• on the other hand a door closer 5 with hydraulic damping double action

which are both located in the high amount 21.

The electric door opener 4 and the door closer 5 are each located in an independent housing 40, 50 and its two housings are fixed to each other.

• un moteur électrique 41 orienté selon un axe moteur A_m parallèle à l'axe de rotation R_v de l'ouvrant et un système de transmission 45 pour entraîner l'ouvrant en rotation et permettre l'ouverture de l'ouvrant 3 dans les deux sens par rapport à l'axe de rotation R_v par rapport à la position fermée ;
• un pignon moteur 42, orienté selon l'axe moteur A_m ;
• un système d'embrayage 43 électromagnétique (à bobine) pour permettre de débrayer le moteur par rapport à l'axe de rotation R_v ;
• un système réducteur 44 ;
• un système d'entraînement 45 constitué d'une courroie animée d'un mouvement sur elle-même qui est horizontal ;
• un axe femelle 46 et qui est mobile en rotation sur lui-même autour de l'axe de rotation R_v ;
• une carte électronique ;
• un capteur d'angle 39 pour détecter la position de l'ouvrant 3 par rapport au dormant 2.

The electric door opener 4 comprises a housing 40 which houses:

• an electric motor 41 oriented along an engine axis A _m parallel to the axis of rotation R _v of the opening and a transmission system 45 to drive the opening in rotation and allow the opening of the opening 3 in both direction relative to the axis of rotation R _v with respect to the closed position;
• a motor pinion 42, oriented along the motor axis A _m ;
• an electromagnetic clutch system (coil) 43 for disengaging the motor with respect to the axis of rotation R _v ;
• a reducing system 44;
• a drive system 45 consisting of a belt driven by a movement on itself which is horizontal;
• a female axis 46 and which is rotatable about itself about the axis of rotation R _v ;
• an electronic card;
• an angle sensor 39 for detecting the position of the opening 3 with respect to the frame 2.

The driving pinion 42 transmits the rotation of the electric motor to a remote clutch system 43 and then a reduction system 44 via a transmission system 45 here constituted by a moving belt horizontally. In contrast to the clutch system 43, the reduction system 44 drives the female axis 46 which accommodates a male secondary axis 51 'of the door closer 5.

Thus, when the clutch system 43 is engaged, the rotation of the electric motor 41 is divided by the reduction system 44 and causes the opening rotation of the opening 3 along the axis R _v . The clutch system 43 is only engaged during the opening phase: the system engages upon receipt of a door opening command and disengage upon disappointment of confirmation that the "door open" position is reached; the engine is therefore engaged for a very short period, which limits the risk of bad action against him and contributes to the overall reliability of the device.

The clutch system 43 is located along a vertical shaft 43 'oriented along an axis R _d : at its upper end this shaft is integral with the transmission system 45 and rests in the housing 40, at its low end on a low bearing 45 '. This shaft 43 'also rests on an annular bearing 47 located between the upper end and the lower end of the shaft which is not completely full but has a vacuum 47' between its center fixed to the shaft 43 ' and its circular periphery which rolls on an adjacent post connected to the housing 40.

The vacuum 47 'serves to make a mechanical connection between a gear 48 located above the annular bearing 47 and a clutch plate 48' located below the annular bearing 47.

Clutch disc assembly 48 '/ gear 48 is both coaxially mounted with shaft 43' and both free to rotate with respect to this shaft through the interposition of several bearings between this assembly and the tree 43 '.

The clutch disc 48 'is rotatable along the axis R _d integrally of the gear 48 and is movable in vertical translation along the shaft 43' under the effect of an electromagnetic field; the application of this electromagnetic field causes the descent of the clutch disk assembly 48 '/ gear 48.

This downward pull is achieved by a flat-headed bell 49.

The bell 49 with the clutch disc 48 'forms what is called an "electromagnetic lock".

• lorsque l'embrayage est ouvert, comme visible en figure 8, la distance d est non nulle : le disque d'embrayage 48' et la cloche 49 ne sont pas solidaires ; toute rotation du moteur 41 entraine la rotation de l'axe R_d mais n'est pas transmise à l'ensemble disque d'embrayage 48'/engrenage 48 qui est ainsi libre ; toute rotation de l'ouvrant 3 est transmise jusqu'à l'ensemble disque d'embrayage 48'/engrenage 48 mais n'est pas transmise plus loin ;
• lorsque l'embrayage est fermé, comme visible en figure 9, la distance d'est nulle : le disque d'embrayage 48' et la cloche 49 sont solidaires, l'engrenage 48 est alors en prise avec le système de transmission 45 ; toute rotation du moteur 41 entraine la rotation de l'axe R_d et cette rotation est transmise à l'engrenage 48.

The electromagnetic field created by an electric current makes it possible to vary the distance d between the clutch disk 48 'and the bell 49:

• when the clutch is open, as visible in figure 8 the distance d is non-zero: the clutch disk 48 'and the bell 49 are not integral; any rotation of the motor 41 causes rotation of the axis R _d but is not transmitted to the clutch disk assembly 48 '/ gear 48 which is thus free; any rotation of the opening 3 is transmitted to the clutch disk assembly 48 '/ gear 48 but is not transmitted further;
• when the clutch is closed, as visible in figure 9 , the distance is zero: the clutch plate 48 'and the bell 49 are integral, the gear 48 is then engaged with the transmission system 45; any rotation of the motor 41 causes the rotation of the axis R _d and this rotation is transmitted to the gear 48.

The distance d is here 0.15 mm.

This clutch system is very reliable and very compact.

The reduction system 44 is interposed (when the direction of transmission of the force required for opening is observed) between the motor 41 of the electric door opener 4 and the female axis 46 intended to be oriented along the axis of rotation R _v , and preferably is interposed between the clutch system 43 and the female axis 46 intended to be oriented along axis of rotation R _v .

The reduction system 44 is a set of movable pinions along axes that are all parallel to the motor axis A _m and to the axis of rotation R _v , while being of different diameters in order to reduce the speed available at the output of electric motor and finally transmitted to the opening, while multiplying the force available at the output of the electric motor and finally transmitted to the opening by the female axis 46.

The figure 10 shows with the black curve, at the top, the torque C (in Nm) which is applied to the axis of the sash as a function of the opening angle G (in degrees) of the sash by a device whose drive system 45 consists of a belt and whose reduction system 44 is a set of movable pinions along axes which are all parallel to the motor axis A _m and the axis of rotation R _v . This pair varies in a fairly high range, from 47 to 23 Nm and it varies continuously.

The gray curve, at the bottom, illustrates the torque that is applied to the axis of the sash as a function of the opening angle of the sash by a device whose drive system and reducing system use only cams. This pair varies in a lower range, from 40 to 12 Nm and it varies discontinuously. The two discontinuities visible in the figure at 32 ° and 65 ° are due to sharp contacts and these contacts cause wear in use.

The door closer 5 comprises a housing 50 which houses a hydraulic damping system of the closure, such as that known for example from the international patent application No. WO 2007/135341 .

The door closer 5 comprises an output shaft 51 projecting outside the casing 50 and oriented vertically along said axis of rotation R _v to allow the closure of said opening in each direction. This output axis 51 has a square outer section.

• une plaque de protection 6 destinée à être positionnée sous ledit ferme-porte 5 et à permettre la liaison au montant haut 21 ;
• une penture haute 7 destinée à être cachée dans le chant supérieur de l'ouvrant et comportant une cavité 71 de section intérieure carrée pour l'accueil de l'axe mâle 51 du ferme-porte ;
• une crapaudine 9 présentant un axe mâle 91 de section extérieure carrée et orienté selon l'axe de rotation R_v ;
• une penture basse 8 destinée à être cachée dans le chant inférieur de l'ouvrant et comportant une cavité 81 de section intérieure carrée pour l'accueil de l'axe mâle 91 de la crapaudine ;
• un faisceau 11 de câbles électrique.

The figure 2 illustrates an exploded view of the device 10 showing that it further comprises:

• a protection plate 6 intended to be positioned under said door closer 5 and to allow the connection to the high post 21;
• an upper hinge 7 intended to be hidden in the upper edge of the opening and having a cavity 71 of square inner section for receiving the male pin 51 of the door closer;
• a clutch 9 having a male axis 91 of square outer section and oriented along the axis of rotation R _v ;
• a low hinge 8 intended to be hidden in the lower edge of the opening and having a cavity 81 of square inner section for the reception of the male axis 91 of the crapaudine;
• a bundle 11 of electric cables.

The hinges comprise means for adjusting the verticality and horizontality of the opening 3 in the open positions and in the closed position.

As visible in figure 2 and 3 , the device 10 is particularly compact: the door opener 4 and the door closer 5 are hidden in the upright 21 and no element of the device is visible on the front or rear of the upright; only the plate of 6 protection is visible when the leaf is not closed at the lower edge of the upright 21, and, of course, that the male axis 51 of the door closer through this protection plate and which is housed in the cavity 71 of the high hinge 7; The high hinge 7 and the low hinge 8 are hidden in the thickness of the opening 3 and are visible only, respectively, by the high edge and the low edge of the opening.

The figure 4 illustrates the assembly of the electric door opener 4 with the door closer 5 and the protection plate 6; this assembly is done in the workshop, well before installation in the opening, thanks to a multitude of screws 12.

The figure 4 shows also the door closer 5 is interposed between the protection plate 6 and the electric door opener 4.

This figure further shows that the electric door opener 4 has a general shape of r, as also visible in figure 5 , so that the motor 41 is located in the base of the r and the wing of the r houses the rest of the electric opener 4: the clutch system 43, the reduction system 44, the drive system 45, the female axis 46, the electronic card, the angle sensor 39, ...

In the device 10, the motor 41 of the electric door opener 4 is located next to the door closer 5 and the clutch system 43 of the electric door opener 4 is located above the closer 5 .

The figure 6 shows that the door closer 5 comprises a traversing shaft oriented along the axis of rotation R _v and consists of the male pin 51 protruding from the housing 50 in the direction of the opening and the male pin 51 'protruding from the housing 50 towards the electric door opener 4 and intended to be positioned in the female axis 46 of the electric door opener 4.

The electronic card drives the electric motor 41 which, associated with the reduction system 44 drives the opening 3 and the output shaft of the hydraulic door closer 5, in opening rotation.

An internal angular sensor makes it possible to manage the positions and stops of the opening and the different operating phases by possibly varying speeds and torques.

At least one "command" (with or without contact) makes it possible to launch an opening request. Additional presence sensors or other information (eg from a motorized lock) may be present to refine the operation of the device. These different information are processed by the map program that drives the electric motor accordingly, managing direction and priorities of passage.

A speed and torque control is present to guarantee the safety of people in case of physical contact with the moving sash.

A feedback to the user is possible to indicate if necessary: the state of the system, the priority direction, an opening in progress ...

The electronic card also drives the magnetic clutch system 43 to maintain the opening in the open or semi-open position.

A permanent and priority control of the signal of a Fire Safety Control Panel is present, to release the mechanism (electric motor and clutch system) in case of fire alarm.

In the absence of specific control or lack of power supply it is possible to manually manipulate the opening without affecting the electronic card.

Example of standard operation

A selector is used to select the operating mode. The possible operating modes are: free motor free, permanent opening mode Push side, permanent opening mode draw side, automatic mode and so-called "Safety" mode.

In automatic mode a specific command (eg a presence sensor) is triggered by the user on the push side. If the leaf is closed or closed (<45 °), the electronic card opens the opening in the pulling direction by driving the electric motor.

Once its open position is reached, the leaf remains motionless for an adjustable time, thanks to the active maintenance of the clutch, the electric motor is then no longer requested.

It is also possible to provide that the manual opening of the opening of an angle greater than 10 ° from its closed position allows to initiate the motorized opening movement in the direction initiated manually.

Once the open position is reached, after a delay and in the absence of a command or active sensor, the clutch is released: the opening closes under the action of the hydraulic door closer 5.

When the device is in permanent open mode, the clutch system remains active.

• Depuis la position fermée, priorité du sens de passage activée : Tout mouvement entamé dans le sens prioritaire de fonctionnement est terminé, quel que soit l'état des entrées en cours (sauf mode Sécurité, toujours prioritaire).

In automatic mode, it is possible to provide priority management:

• From the closed position, priority of the direction of passage activated: Any movement started in the priority direction of operation is completed, whatever the state of the inputs in progress (except Security mode, always priority).

All movement is complete regardless of the state of the current inputs (except Security mode).

• Coupure secteur (ou chute de tension < 10% tension nominale) : la carte électronique s'éteint en relâchant le système d'embrayage 43 et le moteur électrique 41 en moins de 3 secondes, pour assurer la fermeture mécanique de la porte sous l'effet du (ou des) ferme-porte (si la porte à plusieurs ouvrants) ; l'ouvrant ou les ouvrants s'il y en a deux passe(nt) en mode libre.
• Déclenchement CMSI : Après une mise en sécurité par une commande de la CMSI (Centrale de Mise en Sécurité Incendie), la motorisation ne peut être remise en fonctionnement que par une action volontaire sur le sélecteur.
• Cas manipulation en mouvement : Si le passage est forcé alors que le moteur électrique est en fonctionnement, la carte électronique cesse le pilotage (cf. sécurité) le mouvement est stoppé sur l'ouvrant pour laisser la porte libre.
• Cas manipulation embrayage actif: Si le passage est forcé alors que l'embrayage magnétique est actif (position capteur angulaire modifiée), la carte électronique cesse le pilotage et l'ouvrant passe en mode libre.

Special cases :

• Mains failure (or voltage drop <10% nominal voltage): the electronic board turns off by releasing the clutch system 43 and the electric motor 41 in less than 3 seconds, to ensure the mechanical closing of the door under the effect of the door closer (s) (if the door has multiple doors); opening or opening if there are two pass (s) in free mode.
• CMSI trip: After a safety trip by a command from the CMSI (Fire Alarm Control Panel), the drive can only be put back into operation by a voluntary action on the selector.
• Case handling in movement: If the passage is forced while the electric motor is running, the electronic board stops driving (see security) the movement is stopped on the opening to leave the door free.
• Active clutch handling case: If the passage is forced while the magnetic clutch is active (modified angular sensor position), the electronic board stops driving and the opening switches to free mode.
