Description

Dispositif de commande électrique de verrouillage/déverrouillage d'une serrure présentant une fonction anti-panique et serrures anti-paniαue équipées d'un tel dispositif.Electric control device for locking / unlocking a lock having an anti-panic function and anti-panic locks equipped with such a device.
La présente invention concerne un dispositif de commande électrique de verrouillaqe/déverrouillage d'une serrure présentant une fonction anti-panique et des serrures anti¬ panique équipées d'un tel dispositif.The present invention relates to an electrical control device for locking / unlocking a lock having an anti-panic function and anti-panic locks equipped with such a device.
Les serrures à commande électrique sont largement développées dans divers domaines pour accroître la sécurité grâce à l'utilisation de moyens électroniques de commande d'un moteur électrique. Les moyens électroniques eux-mêmes peuvent être commandés par des dispositifs très variés tels que des lecteurs de cartes magnétiques, perforées ou autres, des claviers, des lecteurs de badges, etc.Electrically operated locks are widely developed in various fields to increase security through the use of electronic means for controlling an electric motor. The electronic means themselves can be controlled by a wide variety of devices such as magnetic, punched or other card readers, keyboards, badge readers, etc.
La commande électrique est souvent faite par un moteur électrique réversible commandant un élément de blocage/déblocage mécanique d'un organe de la serrure tel qu'un organe de manoeuvre (bouton ou béquille de porte) ou un organe de verrouillage tel que le pêne. Ainsi, on connaît par GB-A-2 107 778, une serrure verrouillable/déverrouillable de manière électrique. Un élément tel qu'une tige d'accouplement coopère avec une fente ménagée dans un moyeu présentant des moyens d'entraînement du pêne de la serrure. Cet élément est commandé par un solénoïde entre une position d'engagement dans la fente (position verrouillée) et une position de désengagement de la fente (position déverrouillée). Ces deux positions sont obtenues par l'entraînement en rotation d'une tige excentrée montée sur un disque pouvant être entraîné en rotation, la tige coopérant avec une fente linéaire d'une pièce portant l'élément d'accouplement, l'entraînement en rotation du disque par le solénoïde provoquant l'entraînement dudit élément d'accouplement entre ses deux positions.The electrical control is often done by a reversible electric motor controlling a mechanical blocking / unlocking element of a lock member such as an operating member (button or door handle) or a locking member such as the bolt. Thus, GB-A-2 107 778 discloses an electrically lockable / unlockable lock. An element such as a coupling rod cooperates with a slot formed in a hub having means for driving the bolt of the lock. This element is controlled by a solenoid between an engagement position in the slot (locked position) and a disengagement position from the slot (unlocked position). These two positions are obtained by the rotary drive of an eccentric rod mounted on a disc which can be driven in rotation, the rod cooperating with a linear slot of a part carrying the coupling element, the rotary drive of the disc by the solenoid causing the drive of said coupling element between its two positions.
Afin d'assurer une plus grande sécurité dans l'utilisation de ce type de serrure, il est cependant utile de prévoir une fonction anti-panique permettant notamment d'actionner la serrure, par exemple depuis l'intérieur d'un local, sans avoir besoin d'actionner les moyens électroniques de commande du moteur électrique de verrouillage/déverrouillage de la serrure, en particulier lorsque celle-ci est verrouillée.In order to ensure greater security in the use of this type of lock, it is however useful to provide an anti-panic function making it possible in particular to actuate the lock, for example from inside a room, without having need to actuate the electronic means for controlling the electric motor for locking / unlocking the lock, in particular when the latter is locked.
A cet effet, on rend manoeuvrable de manière constante un organe de commande d'une serrure alors même que le second organe de commande peut être verrouillé. De préférence, l'axe dudit premier organe le reliant au mécanisme de serrure est alors distinct de 1 ' axe du second organe de commande et peut ainsi être actionné indépendamment dudit second organe de commande, que celui-ci soit verrouillé ou déverrouillé. Un mécanisme de serrure de ce type peut comporter soit un simple fouillot soit un double fouillot.To this end, a control member of a lock is made maneuverable constantly, even though the second control member can be locked. Preferably, the axis of said first member connecting it to the lock mechanism is then distinct from the axis of the second control member and can thus be actuated independently of said second control member, whether the latter is locked or unlocked. A lock mechanism of this type can comprise either a single follower or a double follower.
On connaît par EP-A-0 172 796, une serrure verrouillable/déverrouillable de manière électrique mais qui peut être manoeuvrée manuellement, au moins d'un côté de la porte, sans avoir recours aux moyens de commande électrique. Le dispositif d'accouplement manoeuvrable électriquement comporte une plaque fixée en rotation sur l'un des axes d*actionnement de la serrure et qui comporte une encoche à sa périphérie dans laquelle un doigt d'accouplement s'engage ou se désengage sous l'effet des moyens d'actionnement électriques. Cependant, le dispositif d'actionnement électrique permettant la manoeuvre du doigt d'accouplement est relativement complexe et encombrant dans la mesure où il comprend le moteur électrique sur lequel est monté un excentrique et une came, l'excentrique étant relié au doigt d'accouplement à l'aide de deux bras de liaison qui, lorsque l'excentrique est entraîné en rotation par le moteur, entraînent en pivotement le doigt d'accouplement entre une position d'accouplement (déverrouillage) et une position de non accouplement (verrouillage) .EP-A-0 172 796 discloses an electrically lockable / unlockable lock which can be operated manually, at least on one side of the door, without using electrical control means. The electrically operable coupling device comprises a plate fixed in rotation on one of the axes of actuation of the lock and which has a notch at its periphery in which a coupling finger engages or disengages under the effect electrical actuation means. However, the electrical actuating device allowing the operation of the coupling finger is relatively complex and bulky insofar as it comprises the electric motor on which is mounted an eccentric and a cam, the eccentric being connected to the coupling finger by means of two link arms which, when the eccentric is driven in rotation by the motor, pivotally drive the coupling finger between a coupling position (unlocking) and a non-coupling position (locking).
Il convient de proposer un dispositif de commande électrique de verrouillage/déverrouillage du second organe de commande qui soit d'une structure et d'une réalisation simple tout en offrant un encombrement réduit et qui permet, en position de verrouillage, d'empêcher la transmission de 1 'actionnement dudit second organe de commande au mécanisme de serrure et en position déverrouillée, de libérer cette transmission et ce quel que soit le type de mécanisme de serrure utilisé.It is necessary to propose an electrical control device for locking / unlocking the second control member which is of a simple structure and construction while offering a reduced bulk and which makes it possible, in the locked position, to prevent transmission. 1 actuation of said second control member to the lock mechanism and in the unlocked position, to release this transmission and this regardless of the type of lock mechanism used.
A cet effet, l'invention a pour objet un dispositif de commande électrique de verrouillage/déverrouillage d'une serrure anti-panique comportant deux organes de commande dont l'un est manoeuvrable de manière constante, du type comprenant un moteur électrique réversible commandant un élément de verrouillage/déverrouillage de l'autre organe de commande de la serrure comprenant un doigt d'accouplement coopérant avec une encoche périphérique prévue sur un disque solidaire de l'autre organe de commande d'une serrure à verrouiller/déverrouiller, caractérisé en ce que le moteur électrique porte une couronne ou un disque solidaire de l'axe du moteur et muni d'une pluralité de saillies axiales excentrées, l'élément de verrouillage/déverrouillage étant constitué par le doigt d'accouplement monté pivotant sur une platine et par un élément de liaison élastique solidaire dudit doigt d'accouplement à une de ses extrémités et dont une extrémité libre est disposée dans la trajectoire desdites saillies axiales en pouvant échapper auxdites saillies.To this end, the subject of the invention is an electrical control device for locking / unlocking a panic lock comprising two control members, one of which is constantly operable, of the type comprising a reversible electric motor controlling a locking / unlocking element of the other control member of the lock comprising a coupling finger cooperating with a peripheral notch provided on a disc secured to the other control member of a lock to be locked / unlocked, characterized in that than the electric motor carries a crown or a disc integral with the axis of the motor and provided with a plurality of eccentric axial projections, the locking / unlocking element being constituted by the coupling finger pivotally mounted on a plate and by a elastic connecting element integral with said coupling finger at one of its ends and one free end of which is disposed in the path of said axial projections, being able to escape from said projections.
Ainsi, l'élément de liaison élastique entraîne en pivotement le doigt d'accouplement qui coopère avec l'encoche périphérique prévue sur le disque solidaire de l'axe de l'organe de commande de la serrure à verrouiller/déverrouiller tel que, par exemple, la poignée de commande extérieure d'une porte.Thus, the elastic connecting element pivots the coupling finger which cooperates with the peripheral notch provided on the disc secured to the axis of the control member of the lock to be locked / unlocked such as, for example , the exterior control handle of a door.
De préférence, le doigt d'accouplement est monté à pivotement à une de ses extrémités sur une saillie de la platine, l'axe de pivotement dudit doigt d'accouplement étant parallèle à ladite platine.Preferably, the coupling finger is pivotally mounted at one of its ends on a projection of the plate, the pivot axis of said coupling finger being parallel to said plate.
La rotation du moteur dans un sens ou dans 1 ' autre provoque, par l'intermédiaire des saillies axiales excentrées, une contrainte sur l'élément de liaison qui, à son tour, entraîne le pivotement du doigt d'accouplement autour de son axe de pivotement sur la platine.The rotation of the motor in one direction or in the other causes, via the eccentric axial projections, a stress on the connecting element which, in turn, causes the pivoting of the coupling finger around its axis of pivoting on the plate.
Le dispositif de commande électrique de verrouillage/déverrouillage peut être utilisé aussi bien avec une serrure anti-panique dont le mécanisme comporte un simple fouillot qu'avec une serrure comportant un double fouillot. Selon le type de serrure utilisé, l'engagement du doigt d'accouplement dans l'encoche permet le verrouillage ou le déverrouillage de ladite serrure.The electrical locking / unlocking control device can be used both with a panic lock, the mechanism of which comprises a single follower, and with a lock comprising a double follower. Depending on the type of lock used, the engagement of the coupling finger in the notch allows the locking or unlocking of said lock.
De ce fait, l'invention a également pour objet une serrure présentant une fonction anti-panique comportant un mécanisme de serrure à simple fouillot et un dispositif de verrouillage/déverrouillage selon l'invention, caractérisée en ce qu'elle comprend un premier organe de commande constamment manoeuvrable dont l'axe, solidaire en rotation du fouillot du mécanisme de serrure, est également solidaire en rotation de la platine sur laquelle est fixée le doigt d'accouplement, la platine étant libre en rotation et un second organe de manoeuvre dont l'extrémité de l'axe est pourvue d'un disque dans lequel est ménagée une encoche périphérique, le doigt d'accouplement, commandé par le moteur électrique, s'engageant ou s'effaçant de ladite encoche périphérique.Therefore, the invention also relates to a lock having an anti-panic function comprising a lock mechanism with single follower and a locking / unlocking device according to the invention, characterized in that it comprises a first constantly maneuverable control member whose axis, integral in rotation with the follower of the lock mechanism, is also integral in rotation of the plate on which the coupling finger is fixed, the plate being free to rotate and a second operating member, the end of the axis of which is provided with a disc in which a peripheral notch is formed, the coupling finger, controlled by the electric motor, engaging or disappearing from said peripheral notch.
Ainsi, lorsque le dispositif de commande électrique de verrouillage/déverrouillage commande l'effacement du doigt d'accouplement hors de l'encoche, l'axe du second organe de commande n'est pas solidaire du mécanisme de serrure et la serrure est en position de verrouillage.Thus, when the electrical locking / unlocking control device clears the coupling finger from the notch, the axis of the second control member is not integral with the lock mechanism and the lock is in position lock.
La commande de l'engagement du doigt d'accouplement dans l'encoche par pivotement du doigt d'accouplement entraîne la solidarisation du second organe de commande avec le mécanisme de serrure, ce qui permet 1 'actionnement de la serrure.Controlling the engagement of the coupling finger in the notch by pivoting the coupling finger leads to the securing of the second control member with the lock mechanism, which allows actuation of the lock.
Lorsque la serrure est du type comportant un double fouillot, elle comprend un premier organe de commande constamment manoeuvrable dont l'axe est solidaire en rotation du premier fouillot et un second organe de commande dont l'axe, ayant son extrémité solidaire en rotation du second fouillot, comporte un disque pourvu d'une encoche périphérique avec laquelle coopère le doigt d'accouplement, la platine étant fixe sur une embase et traversée par l'axe dudit second organe.When the lock is of the type comprising a double follower, it comprises a first constantly operable control member whose axis is integral in rotation with the first follower and a second control member whose axis, having its end integral in rotation with the second follower, comprises a disc provided with a peripheral notch with which the coupling finger cooperates, the plate being fixed on a base and traversed by the axis of said second member.
Ainsi, le doigt d'accouplement, lorsqu'il s'engage dans l'encoche du disque solidaire de l'axe du second organe de commande, bloque 1 ' actionnement dudit second organe et, lorsqu'il s'efface hors de l'encoche, déverrouille 1 »actionnement de l'organe de commande.Thus, the coupling finger, when it engages in the notch of the disc secured to the axis of the second control member, blocks the actuation of said second member and, when it disappears out of the notch, unlocks 1 " actuation of the control member.

la figure 1 est une vue schématique en perspective éclatée d'une serrure à simple fouillot équipée K) d'un dispositif de commande électrique selonFIG. 1 is a schematic exploded perspective view of a single-bolt lock fitted with K) of an electrical control device according to
1 ' invention ;The invention;
la figure 2 est une vue schématique en élévation latérale d'une serrure selon la figure 1 ; et 15 la figure 3 est une vue schématique en élévation latérale d'une serrure à double fouillot équipée d'un dispositif selon l'invention.Figure 2 is a schematic side elevational view of a lock according to Figure 1; and FIG. 3 is a schematic view in side elevation of a double follower lock equipped with a device according to the invention.
0 Le dispositif de commande électrique représenté à la figure 1 comprend un moteur électrique réversible 1 et un doigt d'accouplement 2 monté pivotant sur une platine 3. La platine 3 présente une forme parallélépipèdiques et s'étend le long d'une embase E contre laquelle la serrure est0 The electrical control device shown in FIG. 1 comprises a reversible electric motor 1 and a coupling finger 2 pivotally mounted on a plate 3. The plate 3 has a parallelepiped shape and extends along a base E against which the lock is
25 posée. Le doigt d'accouplement 2 est sensiblement orthogonal à la platine 3.25 asked. The coupling finger 2 is substantially orthogonal to the plate 3.
L'axe du moteur 1 porte une couronne 4 ou disque muni de saillies axiales en forme de plots 5 disposés régulièrement 30 espacés à la périphérie de la couronne 4 ou du disque. Le doigt d'accouplement 2 est muni d'un trou médian 6.The axis of the motor 1 carries a crown 4 or disc provided with axial projections in the form of studs 5 arranged regularly 30 spaced apart at the periphery of the crown 4 or of the disc. The coupling finger 2 is provided with a middle hole 6.
Entre la couronne 4 et le doigt d'accouplement 2 est interposé un élément de liaison élastique 7 constitué par 35 une tige en un matériau élastique. Une extrémité de la tige 7 est en prise dans la trajectoire des plots 5 de manière à pouvoir échapper à ces plots et l'autre extrémité de la tige 7 est enfilée dans le trou 6. Le doigt d'accouplement 2 peut occuper une position dans laquelle une de ses extrémités 2" est maintenue dans une encoche périphérique 14 d'un disque 13 solidaire d'un axe 12 d'une poignée de commande 11.Between the crown 4 and the coupling finger 2 is interposed an elastic connecting element 7 constituted by a rod made of an elastic material. One end of the rod 7 is engaged in the path of the studs 5 so as to be able to escape these studs and the other end of the rod 7 is threaded into the hole 6. The coupling finger 2 can occupy a position in which one of its ends 2 "is held in a peripheral notch 14 of a disc 13 secured to an axis 12 of a control handle 11.
55
En effet, la rotation du moteur 1 dans un sens ou dans l'autre produit, par l'intermédiaire des plots 5, une contrainte sur l'extrémité de la tige 7 qui est entraînée jusqu'à ce qu'elle échappe à un plot 5 et retombe sur le 10 plot 5 suivant dans le sens de rotation. Le déplacement de la tige 7 provoque un pivotement du doigt d'accouplement 2.Indeed, the rotation of the motor 1 in one direction or the other produces, via the studs 5, a stress on the end of the rod 7 which is driven until it escapes a stud 5 and falls back onto the next stud 5 in the direction of rotation. The displacement of the rod 7 causes the coupling finger 2 to pivot.
Selon le sens de rotation du moteur 1, après arrêt du moteur, l'extrémité 2" du doigt d'accouplement 2 est M maintenue dans la position représentée aux figures 1 et 2 dans laquelle elle échappe à l'encoche 14 ou bien dans une position dans laquelle le doigt d'accouplement 2 est engagé dans l'encoche 14. L'axe de pivotement X du doigt d'accouplement 2 est perpendiculaire à la platine 3. 0According to the direction of rotation of the motor 1, after the engine has stopped, the end 2 "of the coupling finger 2 is M held in the position shown in FIGS. 1 and 2 in which it escapes the notch 14 or else in a position in which the coupling finger 2 is engaged in the notch 14. The pivot axis X of the coupling finger 2 is perpendicular to the plate 3. 0
A l'arrêt du moteur 1, qui peut être commandé par tout moyen convenable tel qu'une horloge, la saisie ou le relâchement de la poignée, etc., la tige 7 est toujours en appui sous contrainte sur un plot 5, de sorte que la s position du doigt d'accouplement 2, déterminée par le sens de rotation précédent du moteur 1, est maintenue de manière stable.When the engine 1 stops, which can be controlled by any suitable means such as a clock, the grip or the release of the handle, etc., the rod 7 is always supported under stress on a stud 5, so that the position of the coupling finger 2, determined by the preceding direction of rotation of the motor 1, is maintained stably.
On obtient ainsi un dispositif de commande simple, sûr, peu 0 encombrant et économique.This gives a simple, safe, space-saving and economical control device.
Lorsque la serrure est du type à fonction anti-panique comportant un mécanisme de serrure à simple fouillot (figures 1 et 2), l'organe de commande 8, constamment ^ manoeuvrable, comporte un axe 9 solidaire en rotation du simple fouillot 10 (représenté schématiquement) . L'axe 9 est également solidaire en rotation, à son extrémité, de la platine 3 qui est montée libre en rotation par rapport à l'embase E contre laquelle elle s'étend.When the lock is of the type with anti-panic function comprising a lock mechanism with a single follower (FIGS. 1 and 2), the control member 8, constantly ^ maneuverable, comprises an axis 9 integral in rotation with the simple follower 10 (shown schematically). The axis 9 is also integral in rotation, at its end, with the plate 3 which is mounted free in rotation relative to the base E against which it extends.
L'organe de commande 11, verrouillable et déverrouillable par le dispositif selon l'invention, comporte un axe 12 pourvu à une extrémité d'un disque 13 porteur d'une encoche périphérique 14.The control member 11, lockable and unlockable by the device according to the invention, comprises an axis 12 provided at one end with a disc 13 carrying a peripheral notch 14.
Lorsque le doigt d'accouplement 2 est entraîné en pivotement, il peut s'engager dans l'encoche 14. L'axe 12 de l'organe de commande 11 est ainsi solidarisé au mécanisme de serrure et 1 ' actionnement de cet organe 11 permet 1 ' actionnement du mécanisme de serrure, l'entraînement en rotation de l'axe 12 étant transmis par le doigt d'accouplement 2 à la platine 3, libre en rotation et qui entraîne à son tour l'axe 9 de l'autre organe de manoeuvre 8 lié au fouillot 10 du mécanisme de serrure.When the coupling finger 2 is pivotally driven, it can engage in the notch 14. The axis 12 of the control member 11 is thus secured to the lock mechanism and the actuation of this member 11 allows 1 actuation of the lock mechanism, the rotation drive of the axis 12 being transmitted by the coupling finger 2 to the plate 3, free in rotation and which in turn drives the axis 9 of the other member of operation 8 linked to the follower 10 of the lock mechanism.
Pour verrouiller la serrure, le doigt d'accouplement 2 est effacé de l'encoche 14 et l'axe 12 de l'organe de commande 11 est désolidarisé de mécanisme de la serrure, l'organe de commande 11 étant alors fou en rotation.To lock the lock, the coupling finger 2 is erased from the notch 14 and the axis 12 of the control member 11 is disconnected from the lock mechanism, the control member 11 then being mad in rotation.
La figure 3 représente une serrure à fonction anti-panique équipée d'un dispositif selon l'invention et dont le mécanisme de serrure comporte un double fouillot. Les mêmes références que pour les figures 1 et 2 sont utilisées avec un indice prime pour les mêmes éléments qu'aux figures 1 et 2.FIG. 3 represents a lock with an anti-panic function equipped with a device according to the invention and the lock mechanism of which comprises a double follower. The same references as for FIGS. 1 and 2 are used with a prime index for the same elements as in FIGS. 1 and 2.
L'organe de commande 8' comporte un axe 9' relié au premier fouillot 10', ce qui permet 1 'actionnement du mécanisme de serrure à tout moment, tandis que le second fouillot 10' ' est relié à l'axe 12' du second organe de commande 11' .The control member 8 'has an axis 9' connected to the first follower 10 ', which allows actuation of the lock mechanism at any time, while the second follower 10' 'is connected to the axis 12' of the second control member 11 '.
La platine 3' est fixée à l'embase E contre laquelle elle s'étend par tous moyens de fixation, par exemple à l'aide de vis. Elle comporte un alésage 15' traversé par l'axe 12', ledit axe 12' étant libre en rotation dans l'alésageThe plate 3 'is fixed to the base E against which it extends by any fixing means, for example using quote. It has a bore 15 'crossed by the axis 12', said axis 12 'being free to rotate in the bore
15' .15 '.
L'engagement du doigt d'accouplement 2' dans l'encoche 14' du disque 13' porté par l'axe 12' bloque en rotation ledit axe 12', ce qui empêche 1 ' actionnement de la serrure. L'effacement du doigt d'accouplement 2' hors de l'encoche libère alors l'organe de commande 11'.The engagement of the coupling finger 2 ′ in the notch 14 ′ of the disc 13 ′ carried by the axis 12 ′ blocks said axis 12 ′ in rotation, which prevents the actuation of the lock. Erasing the coupling finger 2 'from the notch then releases the control member 11'.
Ainsi, selon l'invention, on a un dispositif de commande électrique de verrouillage/déverrouillage d'une serrure présentant une fonction anti-panique et ce quel que soit le type de serrure qu'il équipe. Thus, according to the invention, there is an electrical control device for locking / unlocking a lock having an anti-panic function and this regardless of the type of lock which it equips.
