Abstract

The door lock is turned by a rectangular section shaft (8) which is permanently connected to an interior handle. The rectangular section shaft (8) may be connected to an external shaft (16) and handle (18) through coupling members (40,52). The coupling members (40,52) are made solid mechanically by a radial pin (68) when it bridges them and in this position the lock may be operated by the external handle (18). When the motor (120) is started by the keyboard (28) a ring (104) with an internal cam profile substitutes a ball (108) for the pin tip (78) and this releases the coupling members isolating the lock from the outside.

Description

La présente invention concerne un dispositif d'accouplement débrayable d'une première tige avec une deuxième tige coaxiales, associées chacune à une poignée d'actionnement d'une serrure, l'une des deux tiges étant engagée dans un fouillot de commande de la serrure.The present invention relates to a disengageable coupling device for a first rod with a second coaxial rod, each associated with a handle for actuating a lock, one of the two rods being engaged in a lock control nut .

L'invention concerne plus particulièrement un dispositif d'accouplement débrayable de ce type comportant en outre, disposés dans un boîtier, un premier organe d'accouplement solidaire de la première tige et monté libre en rotation dans un trou axial d'un deuxième organe d'accouplement solidaire de la deuxième tige, le premier organe d'accouplement comportant un doigt mobile radialement de solidarisation avec le deuxième organe d'accouplement et un organe de rappel du doigt vers la position de solidarisation, le deuxième organe d'accouplement comportant un trou traversant radial de réception d'une extrémité du doigt de solidarisation.The invention relates more particularly to a disengageable coupling device of this type further comprising, arranged in a housing, a first coupling member integral with the first rod and mounted for free rotation in an axial hole of a second member d coupling integral with the second rod, the first coupling member comprising a radially movable finger for securing with the second coupling member and a member for returning the finger to the securing position, the second coupling member comprising a hole radial through receiving one end of the securing finger.

Le présent dispositif d'accouplement débrayable est destiné à être associé sur une porte à une serrure de type classique, dont le pêne demi-tour est actionné par des béquilles ou des boutons de porte, le pêne dormant de cette même serrure étant actionné par une clé adaptée ou un dispositif de commande électrique à code.The present disengageable coupling device is intended to be associated on a door with a lock of the conventional type, the bolt of which is turned by crutches or door knobs, the deadbolt of this same lock being actuated by a suitable key or an electrical code control device.

Un tel dispositif d'accouplement débrayable est destiné à être interposé entre les deux béquilles disposées de chaque côté de la serrure et rendre ainsi débrayable l'accouplement entre les tiges respectives de chacune de ces béquilles, l'une de ces tiges étant solidaire du fouillot de commande de la serrure.Such a disengageable coupling device is intended to be interposed between the two crutches arranged on each side of the lock and thus make disengageable the coupling between the respective rods of each of these crutches, one of these rods being integral with the follower of the lock.

Ainsi, en position débrayée, ce dispositif permet d'interdire l'actionnement du pêne demi-tour de la serrure à partir de l'une des deux béquilles qui est rendue folle. L'autre béquille par contre, même lorsque le dispositif est en position débrayée, est en mesure de commander la serrure.Thus, in the disengaged position, this device makes it possible to prohibit the actuation of the bolt turn of the lock from one of the two crutches which is driven mad. The other stand, on the other hand, even when the device is in the disengaged position, is able to control the lock.

Ce type de dispositif est particulièrement utile pour des portes de chambres d'hôtel ou des portes intérieures de bureau.This type of device is particularly useful for doors of hotel rooms or interior office doors.

Dans ce cas, le dispositif d'accouplement est disposé sur le panneau extérieur de la porte et permet d'interdire l'ouverture de la porte par désolidarisation de la béquille extérieure de la tige d'actionnement du pêne demi-tour de la serrure. L'accès est alors interdit même sans utiliser le verrouillage à clé. Par contre, quel que soit l'état d'accouplement, l'ouverture est possible depuis la béquille disposée sur le panneau de porte intérieur.In this case, the coupling device is disposed on the exterior panel of the door and makes it possible to prohibit the opening of the door by detaching the exterior crutch from the actuating rod of the latch turn latch. Access is then prohibited even without using the key lock. On the other hand, whatever the state of coupling, the opening is possible from the crutch arranged on the interior door panel.

Il existe déjà dans l'état de la technique des dispositifs permettant de débrayer l'accouplement de deux tiges coaxiales de commande d'une serrure associées chacune à une béquille.There already exist in the state of the art devices making it possible to disengage the coupling of two coaxial rods for controlling a lock, each associated with a crutch.

En particulier, la demande de brevet français publiée sous le numéro 2.686.117 décrit un tel dispositif, dans lequel les deux organes d'accouplement sont des cylindres creux disposés bout à bout, l'un des deux cylindres comportant à son extrémité en regard de l'autre cylindre un doigt de solidarisation, chargé par un ressort. Ce doigt de solidarisation est mobile radialement entre une position escamotée à l'intérieur de l'organe d'accouplement et une position active de solidarisation dans laquelle une extrémité de celui-ci est reçue dans une rainure radiale de la face d'extrémité de l'organe d'accouplement complémentaire.In particular, the French patent application published under number 2,686,117 describes such a device, in which the two coupling members are hollow cylinders arranged end to end, one of the two cylinders having at its end opposite the other cylinder a securing finger, loaded by a spring. This securing finger is movable radially between a retracted position inside the coupling member and an active securing position in which one end of the latter is received in a radial groove of the end face of the 'complementary coupling member.

Un organe formant poussoir, mobile en translation dans la structure fixe du dispositif permet de repousser le doigt de solidarisation en position escamotée et ainsi permettre le débrayage des deux organes d'accouplement.A pusher member, movable in translation in the fixed structure of the device makes it possible to push the securing finger back into the retracted position and thus allow the disengagement of the two coupling members.

Un inconvénient de ce dispositif réside dans le fait qu'en position débrayée, l'organe formant poussoir rencontre le trajet de déplacement de l'organe d'accouplement portant le doigt de solidarisation, limitant ainsi le débattement angulaire de celui-ci.A drawback of this device lies in the fact that in the disengaged position, the pusher member meets the path of movement of the coupling member carrying the securing finger, thereby limiting the angular movement thereof.

Un autre inconvénient de ce dispositif connu résulte du fait que l'extrémité du doigt de solidarisation est reçue dans une rainure de l'organe d'accouplement complémentaire, la liaison n'étant alors effectuée entre ces deux organes d'accouplement que par les faces latérales opposées de cette rainure, ce qui rend cette liaison relativement fragile et nécessite des ajustements précis des différentes pièces.Another drawback of this known device results from the fact that the end of the securing finger is received in a groove of the complementary coupling member, the connection then being made between these two coupling members only by the faces opposite sides of this groove, which makes this connection relatively fragile and requires precise adjustments of the different parts.

Il est par ailleurs connu, d'après le brevet US-A-5,027,629 de disposer dans un dispositif d'accouplement débrayable un doigt de solidarisation à l'intérieur d'un premier organe d'accouplement, ce dernier étant reçu en rotation dans un deuxième organe d'accouplement. Le deuxième organe d'accouplement comporte un évidement de réception de l'extrémité du doigt de solidarisation dans lequel est disposé en outre un poussoir actionné par un dispositif adapté disposé à l'extérieur des premier et deuxième organes d'accouplement afin de définir l'état d'accouplement du dispositif.It is also known, from US-A-5,027,629 to have in a disengageable coupling device a securing finger inside a first coupling member, the latter being received in rotation in a second coupling member. The second coupling member includes a recess for receiving the end of the securing finger in which is further disposed a pusher actuated by a suitable device disposed outside the first and second coupling members in order to define the state of coupling of the device.

Le dispositif d'accouplement débrayable selon l'invention a pour but de remédier à ces inconvénients, tout en permettant un actionnement facile de celui-ci, notamment en étant compatible avec l'utilisation d'un moteur électrique, ce dispositif étant réalisable facilement et à faible coût tout en garantissant une protection sûre contre les intrusions.The purpose of the disengageable coupling device according to the invention is to remedy these drawbacks, while allowing easy actuation thereof, in particular by being compatible with the use of an electric motor, this device being easily achievable and low cost while ensuring secure protection against intrusion.

The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the drawings in which:
  • FIG. 1 is a perspective view of a disengageable coupling device according to the invention mounted on a door provided with a conventional lock,

Sur la figure 1, on a représenté une portion d'une porte 2 dans l'épaisseur de laquelle est reçue une serrure 4 de type classique, munie d'un pêne demi-tour 6 et d'un pêne dormant 7.In FIG. 1, a portion of a door 2 is shown in the thickness of which is received a lock 4 of the conventional type, provided with a latch bolt 6 and a dead bolt 7.

De manière classique, le pêne demi-tour 6 est commandé par une tige de section carrée 8 introduite dans le fouillot de commande (non représenté) de la serrure, et à l'extrémité de laquelle est fixée une béquille ou poignée d'actionnement 10.Conventionally, the latch bolt 6 is controlled by a rod of square section 8 introduced into the control nut (not shown) of the lock, and at the end of which is fixed a crutch or actuating handle 10 .

De même, le pêne dormant 7 est commandé par un dispositif de verrouillage non représenté, disposé dans la serrure.Likewise, the deadbolt 7 is controlled by a locking device, not shown, arranged in the lock.

La porte 2 représentée à la figure 1 est supposée être la porte d'un bureau. Sur le panneau extérieur de la porte, c'est-à-dire à l'extérieur du bureau, est fixé un dispositif d'accouplement débrayable 14 de la tige de section carrée 8 engagée dans le fouillot (non représenté) de la serrure, avec une tige complémentaire coaxiale 16 de commande du pêne demi-tour 6 de la serrure 4 depuis l'extérieur. La tige 16 dont une extrémité fait saillie en dehors du dispositif d'accouplement débrayable 14 est munie d'une béquille ou poignée d'actionnement 18.Door 2 shown in Figure 1 is assumed to be the door to an office. On the outside panel of the door, that is to say outside of the office, is fixed a disengageable coupling device 14 of the square section rod 8 engaged in the follower (not shown) of the lock, with a coaxial complementary rod 16 for controlling the latch bolt 6 of the lock 4 from the outside. The rod 16, one end of which projects outside the disengageable coupling device 14 is provided with a stand or actuating handle 18.

Ainsi, le pêne demi-tour 6 de la serrure est commandé par la tige 8 de section carrée solidaire de la béquille intérieure 10, le dispositif d'accouplement débrayable étant disposé entre la tige 8 et la tige 16 associée à la béquille d'actionnement extérieure 18.Thus, the latch bolt 6 of the lock is controlled by the rod 8 of square section secured to the interior stand 10, the disengageable coupling device being disposed between the rod 8 and the rod 16 associated with the actuating stand exterior 18.

En position débrayée, c'est-à-dire lorsque les tiges 8 et 16 ne sont pas solidarisées, l'ouverture de la porte est impossible par actionnement de la béquille 18, mais reste possible par actionnement de la béquille intérieure 10.In the disengaged position, that is to say when the rods 8 and 16 are not secured, the opening of the door is impossible by actuation of the crutch 18, but remains possible by actuation of the interior crutch 10.

Sur la figure 2 est représenté en détail l'agencement du mécanisme intérieur du dispositif d'accouplement débrayable.In Figure 2 is shown in detail the arrangement of the inner mechanism of the disengageable coupling device.

Ce dispositif 14 comporte un boîtier allongé 24 de protection du mécanisme d'accouplement, dont le profil extérieur est visible sur la figure 1, réalisé par exemple par usinage dans un bloc de métal massif. Il présente deux faces latérales verticales parallèles 24A, 24B reliées l'une à l'autre par des portions planes successives définissant la face principale du dispositif.This device 14 comprises an elongated housing 24 for protecting the coupling mechanism, the external profile of which is visible in FIG. 1, produced for example by machining in a block of solid metal. It has two parallel vertical side faces 24A, 24B connected to each other by successive flat portions defining the main face of the device.

Sur cette face principale sont disposées successivement une portion de commande inclinée 26 sur laquelle fait saillie un clavier à touches 28 de commande de l'état de solidarisation du dispositif d'accouplement débrayable, suivie d'une portion centrale 30 verticale munie d'un trou central 32 de passage de la tige 16 associée à la béquille extérieure 18 et enfin, reliée à cette face centrale 30 par des portions inclinées successives, une seconde portion verticale en retrait 34.On this main face are successively disposed an inclined control portion 26 on which protrudes a keyboard with keys 28 for controlling the state of attachment of the disengageable coupling device, followed by a central central portion 30 provided with a hole central 32 for passage of the rod 16 associated with the outer stand 18 and finally, connected to this central face 30 by successive inclined portions, a second recessed vertical portion 34.

Au lieu du clavier à touches, le dispositif peut comporter un lecteur de carte magnétique ou un autre système de commande à code.Instead of the keypad, the device may include a magnetic card reader or other code control system.

Le boîtier 24 est complété par un couvercle plat 36 de fermeture fixé au boîtier 24 par l'intermédiaire de avis de fixation 38.The box 24 is completed by a flat closing cover 36 fixed to the box 24 by means of fixing notices 38.

Ce premier organe d'accouplement 40 comporte une première portion cylindrique 44 reçue dans un passage 46 formant palier du couvercle 36 dans lequel le premier organe d'accouplement 40 est libre de tourner autour de l'axe de la tige 8.The rod 8 engaged in the follower (not shown) for controlling the U-bolt 6 and one of whose ends is integral with the inner stand 10 has a first coupling member 40 fixed at its second end by a key 42 This first coupling member 40 comprises a first cylindrical portion 44 received in a passage 46 forming a bearing of the cover 36 in which the first coupling member 40 is free to rotate around the axis of the rod 8.

L'organe 40 comporte en outre une seconde portion cylindrique coaxiale 48 de plus grand diamètre. Entre ces première et seconde portions cylindriques 44 et 48 est disposée une jambe radiale 50 de butée adaptée pour limiter la course angulaire du premier organe d'accouplement 40 le long de la surface intérieure du couvercle 36.The member 40 further comprises a second coaxial cylindrical portion 48 of larger diameter. Between these first and second cylindrical portions 44 and 48 is disposed a radial leg 50 of abutment adapted to limit the angular travel of the first coupling member 40 along the inner surface of the cover 36.

La tige 16 liée à la béquille extérieure 18 est solidaire à son extrémité engagée à l'intérieur du boîtier 24 d'un deuxième organe d'accouplement 52 auquel elle est fixée par une clavette 54. Ce deuxième organe d'accouplement 52 comporte une première portion cylindrique 56 reçue dans un alésage 58 formant palier réalisé dans le boîtier 24 dans le prolongement du passage 32 de la tige 16. Le deuxième organe d'accouplement 52 comporte une deuxième portion cylindrique 60 coaxiale de plus grand diamètre, séparée de la première portion 56 par une jambe radiale 62 formant butée et adaptée pour limiter la course angulaire du deuxième organe d'accouplement 52 le long de la surface intérieure du boîtier 24.The rod 16 linked to the outer stand 18 is secured at its end engaged inside the housing 24 of a second coupling member 52 to which it is fixed by a key 54. This second coupling member 52 comprises a first cylindrical portion 56 received in a bore 58 forming a bearing produced in the housing 24 in the extension of the passage 32 of the rod 16. The second coupling member 52 comprises a second cylindrical coaxial portion 60 of larger diameter, separated from the first portion 56 by a radial leg 62 forming a stop and adapted to limit the angular travel of the second coupling member 52 along the interior surface of the housing 24.

Comme cela est représenté sur les figures 2 et 3, le deuxième organe d'accouplement 52 comporte à son extrémité opposée à la tige 16 dans sa portion cylindrique 60 de plus gros diamètre un trou borgne axial 64 dans lequel est reçue la portion de plus grand diamètre 48 du premier organe d'accouplement 40.As shown in Figures 2 and 3, the second coupling member 52 has at its end opposite the rod 16 in its cylindrical portion 60 of larger diameter an axial blind hole 64 in which is received the larger portion diameter 48 of the first coupling member 40.

Ce dernier comporte dans sa portion de plus grand diamètre 48 reçue dans le trou borgne 64 un logement diamétral 66 formé de deux trous coaxiaux successifs de diamètres différents débouchant de part et d'autre de la portion cylindrique 48. Dans ce logement 66 est reçu un doigt de solidarisation 68 formé par une tige 70 prolongée axialement par un fût de plus gros diamètre 72 dans lequel est ménagé un siège 72a de réception d'extrémité d'un ressort de rappel hélicoïdal 74 dont l'autre extrémité prend appui sur la surface latérale intérieure du trou borgne 64.The latter comprises in its portion of larger diameter 48 received in the blind hole 64 a diametral housing 66 formed of two successive coaxial holes of different diameters opening on either side of the cylindrical portion 48. In this housing 66 is received a joining finger 68 formed by a rod 70 extended axially by a larger diameter barrel 72 in which is formed a seat 72a for receiving the end of a helical return spring 74 whose other end takes support on the inner lateral surface of blind hole 64.

Le deuxième organe d'accouplement 52 comporte dans sa portion de plus grand diamètre 60 en regard du doigt de solidarisation 68 porté par le premier organe d'accouplement 40 un trou traversant radial 76 de réception d'une extrémité 78 du doigt de solidarisation 68. Le trou 76 est avantageusement de section constante. Telle que représentée sur les figures 2 et 3, l'extrémité 78 du doigt est reçue dans le trou 76.The second coupling member 52 comprises, in its portion of larger diameter 60 facing the connection finger 68 carried by the first coupling member 40, a radial through hole 76 for receiving an end 78 of the connection finger 68. The hole 76 is advantageously of constant section. As shown in FIGS. 2 and 3, the end 78 of the finger is received in the hole 76.

La portion de plus gros diamètre 60 du deuxième organe d'accouplement 52 est reçue mobile en rotation dans un alésage 80 d'une embase 82 formant une structure de support fixe. Cette dernière représentée en perspective sur la figure 4 a une base rectangulaire 84 reçue dans un logement intérieur de forme complémentaire 86 du boîtier 24 dans lequel elle est fixée par l'intermédiaire de vis 87.The larger diameter portion 60 of the second coupling member 52 is received movable in rotation in a bore 80 of a base 82 forming a fixed support structure. The latter shown in perspective in FIG. 4 has a rectangular base 84 received in an interior housing of complementary shape 86 of the housing 24 in which it is fixed by means of screws 87.

Sur une face en regard du boîtier 24 de la base 84 est ménagé un évidement 88 (figure 2) de forme générale cylindrique pour le passage de la jambe 62 du deuxième organe d'accouplement 52. Sur sa face opposée, la base 84 est prolongée par une portion cylindrique 90 représenté sur la figure 4 venue de matière et traversée par l'alésage 80. Cette portion cylindrique 90 a son axe parallèle mais décalé par rapport à l'axe de l'alésage 80. Elle présente en outre à son extrémité libre une portion cylindrique 92 coaxiale de plus faible diamètre.On a facing face of the housing 24 of the base 84 is formed a recess 88 (FIG. 2) of generally cylindrical shape for the passage of the leg 62 of the second coupling member 52. On its opposite face, the base 84 is extended by a cylindrical portion 90 shown in FIG. 4 integrally formed and traversed by the bore 80. This cylindrical portion 90 has its axis parallel but offset with respect to the axis of the bore 80. It further has at its end free a coaxial cylindrical portion 92 of smaller diameter.

Sur la face d'extrémité plane 93 de celle-ci est vissé un flasque 94 cylindrique plat de même diamètre extérieur que la portion de cylindre 90, délimitant avec celle-ci une rainure périphérique 96.On the flat end face 93 of the latter is screwed a flat cylindrical flange 94 of the same outside diameter as the cylinder portion 90, delimiting therewith a peripheral groove 96.

Comme représenté en détail sur la figure 4, le flasque 94 est traversé par un trou central 95 prolongeant l'alésage 80 de l'embase 82 et de même diamètre que celui-ci. Il comporte en outre sur sa face en regard de l'embase 82 une couronne intérieure 98 en surépaisseur de même diamètre extérieur que la portion cylindrique 92 de l'embase 82 et dont la surface périphérique forme avec la surface périphérique de la portion 92 le fond de la rainure 96. Cette couronne 98 est prolongée vers l'extérieur du flasque 94 en travers de la rainure 96 par une portion plane en saillie radiale 100.As shown in detail in Figure 4, the flange 94 is traversed by a central hole 95 extending the bore 80 of the base 82 and of the same diameter as the latter. It further comprises on its face opposite the base 82 an inner ring 98 in excess thickness of the same outside diameter as the cylindrical portion 92 of the base 82 and whose peripheral surface forms with the peripheral surface of the portion 92 the bottom of the groove 96. This ring 98 is extended towards the outside of the flange 94 across the groove 96 by a planar portion projecting radially 100.

Un trou de guidage radial 102 formé par des canaux 102A, 102B ménagés respectivement dans l'embase 82 et le flasque 94 débouche à l'une de ses extrémités dans l'alésage 80 de l'embase 82 prolongé par le trou 95 du flasque 94 et à l'autre de ses extrémités dans la surface latérale extérieure de la portion cylindrique 90 de l'embase 82 prolongée par le flasque 94. Ce trou 102 est partiellement ménagé dans les parois latérales de la rainure périphérique 96 dans la partie rétrécie de celle-ci par la portion en saillie radiale 100 du flasque 94. En particulier, le canal 102A a une portion d'extrémité ménagée dans la paroi latérale de la rainure 96 portée par l'embase 82 qui débouche sur la portion cylindrique 90 de celle-ci. De même, le canal 102B ménagé dans le flasque 94 a une portion d'extrémité qui s'étend dans la portion plane en saillie radiale 100 jusqu'à la périphérie du flasque 94.A radial guide hole 102 formed by channels 102A, 102B formed respectively in the base 82 and the flange 94 opens at one of its ends in the bore 80 of the base 82 extended by the hole 95 of the flange 94 and at the other of its ends in the external lateral surface of the cylindrical portion 90 of the base 82 extended by the flange 94. This hole 102 is partially formed in the side walls of the peripheral groove 96 in the narrowed part of that -this by the radial projecting portion 100 of the flange 94. In particular, the channel 102A has an end portion formed in the side wall of the groove 96 carried by the base 82 which opens onto the cylindrical portion 90 thereof. this. Likewise, the channel 102B formed in the flange 94 has an end portion which extends in the planar portion projecting radially 100 as far as the periphery of the flange 94.

Une bague 104 représentée sur la figure 4 est montée à cheval sur l'extrémité de la portion cylindrique 90 et sur la surface latérale du flasque 94. Elle est munie sur sa paroi cylindrique intérieure d'une rampe 106 de hauteur progressivement croissante suivant environ 260° de sa périphérie et reçue dans la rainure 96 définie par l'assemblage du flasque 94 sur l'embase 82. La rampe 106 comporte sur sa paroi latérale à son extrémité de plus grande hauteur un pion latéral d'arrêt 107, de limitation du mouvement en rotation de la rampe 104 dans la rainure 96 par coopération de celui-ci avec les parois latérales de la portion plane 100 en saillie radiale dans la rainure 96 et formant butée complémentaire.A ring 104 shown in Figure 4 is mounted astride the end of the cylindrical portion 90 and on the lateral surface of the flange 94. It is provided on its inner cylindrical wall with a ramp 106 of progressively increasing height according to approximately 260 ° of its periphery and received in the groove 96 defined by the assembly of the flange 94 on the base 82. The ramp 106 has on its side wall at its end of greatest height a lateral stop pin 107, limiting the rotational movement of the ramp 104 in the groove 96 by cooperation of the latter with the side walls of the planar portion 100 projecting radially in the groove 96 and forming a complementary stop.

A l'intérieur du trou radial 102 est reçue une première bille 108 formant organe de substitution. La bille 108 a un diamètre égal à la profondeur du trou radial 76 du deuxième organe d'accouplement 52. Elle est repoussée vers l'alésage 80 par un poussoir constitué d'un ressort hélicoïdal 110 et de deux billes d'extrémité 112, 114 disposées de part et d'autre du ressort.Inside the radial hole 102 is received a first ball 108 forming a substitution member. The ball 108 has a diameter equal to the depth of the radial hole 76 of the second coupling member 52. It is pushed back towards the bore 80 by a pusher consisting of a helical spring 110 and two end balls 112, 114 arranged on either side of the spring.

La longueur occupée par les deux billes 112, 114 et le ressort 110 du poussoir est égale à la profondeur du trou 102 minorée du diamètre de la bille 108 formant organe de substitution ; ainsi, le trou 102 peut contenir simultanément le poussoir et l'organe de substitution sans que le ressort ne soit comprimé.The length occupied by the two balls 112, 114 and the spring 110 of the pusher is equal to the depth of the hole 102 minus the diameter of the ball 108 forming a substitution member; thus, the hole 102 can simultaneously contain the pusher and the substitution member without the spring being compressed.

La bille 114 est en contact avec la rampe 106 formant came ou la paroi intérieure de la bague 104 alors que la bille 112 est en contact avec la bille 108 et repousse celle-ci vers l'alésage axial 80 de l'embase 82 sous l'action de la rampe 106 transmise par le ressort 110 dont la valeur du coefficient de raideur est choisie supérieure à celle du ressort 74 repoussant le doigt 68.The ball 114 is in contact with the ramp 106 forming a cam or the inner wall of the ring 104 while the ball 112 is in contact with the ball 108 and pushes the latter towards the axial bore 80 of the base 82 under the action of the ramp 106 transmitted by the spring 110, the value of the stiffness coefficient of which is chosen to be greater than that of the spring 74 repelling the finger 68.

La bague de commande 104 comporte sur une portion de sa périphérie extérieure une couronne dentée 116 actionnée par un pignon d'entraînement 118 monté sur l'arbre d'un moteur d'entraînement 120 et qui coopère avec la couronne dentée 116 par l'intermédiaire de pignons de démultiplication coaxiaux 121.The control ring 104 has on a portion of its outer periphery a toothed ring 116 actuated by a drive pinion 118 mounted on the shaft of a drive motor 120 and which cooperates with the toothed ring 116 through of coaxial reduction gears 121.

Le moteur électrique 120 est alimenté par une batterie non représentée reçue dans le boîtier 24 et est piloté par un dispositif de pilotage 122 connu, relié au clavier 28 et adapté pour piloter le moteur 120 en fonction de la composition de codes prédéterminés sur le clavier à touches 28 en vue de commander l'état du dispositif d'accouplement.The electric motor 120 is powered by a battery (not shown) received in the housing 24 and is controlled by a known control device 122, connected to the keyboard 28 and adapted to control the motor 120 according to the composition of predetermined codes on the keypad 28 to control the state of the coupling device.

Des micro-interrupteurs 123, représentés sur la figure 3, sont disposés sur l'embase 82 à la périphérie de la bague 104 et sont adaptés pour être déclenchés par des saillies 123A représentées sur la figure 4 disposées sur la surface extérieure de la bague 104 afin de stopper le moteur 120 lorsque la bague a atteint une position extrême de sa course.Micro-switches 123, shown in Figure 3, are arranged on the base 82 at the periphery of the ring 104 and are adapted to be triggered by projections 123A shown in Figure 4 arranged on the outer surface of the ring 104 in order to stop the motor 120 when the ring has reached an extreme position of its travel.

Un ressort hélicoïdal 124 disposé autour de la tige 16 dans un logement adapté 126 du boîtier 24 a ses deux extrémités liées à un pion non représenté de la jambe de blocage 62 du deuxième organe d'accouplement 52.A helical spring 124 disposed around the rod 16 in a suitable housing 126 of the housing 24 has its two ends linked to a not shown pin of the locking leg 62 of the second coupling member 52.

Ce ressort 124 constitue un organe de rappel du deuxième organe d'accouplement et de la béquille associée dans une position neutre, correspondant à celle représentée aux figures.This spring 124 constitutes a return member of the second coupling member and of the associated stand in a neutral position, corresponding to that shown in the figures.

Une butée constituée par une tige telle qu'une vis sans tête 128 par exemple est reçue dans un trou taraudé 130 de l'embase 82 prolongé dans le flasque 94 et dépasse de part et d'autre de cette embase pour limiter la course angulaire des jambes de blocage respectivement 50 et 62 des premier et deuxième organes d'accouplement 40 et 52.A stop constituted by a rod such as a headless screw 128 for example is received in a tapped hole 130 of the base 82 extended in the flange 94 and protrudes on either side of this base to limit the angular travel of the locking legs 50 and 62 respectively of the first and second coupling members 40 and 52.

Deux trous taraudés symétriques 130 sont disposés de part et d'autre du trou radial 102 afin de déterminer sélectivement par insertion dans l'un d'eux de la vis 128 deux sens différents opposés de limitation de la course en rotation des béquilles d'actionnement de la serrure.Two symmetrical tapped holes 130 are arranged on either side of the radial hole 102 in order to selectively determine by inserting in one of them the screw 128 two different opposite directions of limitation of the rotation stroke of the actuating legs of the lock.

Sur les figures 2 et 3, on a représenté le dispositif d'accouplement débrayable en position embrayée ou de liaison.In Figures 2 and 3, there is shown the disengageable coupling device in the engaged or connecting position.

Dans cette situation, comme cela est visible sur la figure 3, la bague 104 est placée de telle façon que la rampe 106 portant la surface de came ne soit pas en contact contre la bille d'extrémité 114 du poussoir et que cette dernière soit en contact avec la paroi intérieure de la bague 104. Dans cette situation, la première bille 108 formant organe de substitution est escamotée dans une portion d'extrémité du trou radial 102 formant un logement d'escamotage pour celle-ci et l'extrémité 78 du doigt de solidarisation 68 est reçue dans le trou radial 76 du deuxième organe d'accouplement 52, permettant ainsi une solidarisation des premier et deuxième organes d'accouplement.In this situation, as can be seen in FIG. 3, the ring 104 is placed in such a way that the ramp 106 carrying the cam surface is not in contact with the end ball 114 of the pusher and that the latter is in contact with the inner wall of the ring 104. In this situation, the first ball 108 forming a substitution member is retracted into an end portion of the radial hole 102 forming a retraction housing for the latter and the end 78 of the securing finger 68 is received in the radial hole 76 of the second coupling member 52, thus allowing a securing first and second coupling members.

Dans cette situation, l'action sur l'une ou l'autre des béquilles 10, 18 permet la commande du pêne demi-tour et, si la serrure n'est pas verrouillée par son pêne dormant, l'ouverture de la porte.In this situation, the action on one or the other of the crutches 10, 18 allows the control of the latch bolt and, if the lock is not locked by its dead bolt, the opening of the door.

Afin de procéder à la désolidarisation des deux tiges du dispositif, la composition d'un code particulier sur le clavier à touches 28 pilote le moteur 120 pour qu'il entraîne en rotation la bague 104 dans le sens inverse des aiguilles d'une montre pour atteindre la position représentée aux figures 5 et 6.In order to separate the two rods from the device, the composition of a particular code on the keypad 28 controls the motor 120 so that it rotates the ring 104 in an anti-clockwise direction to reach the position shown in Figures 5 and 6.

Dans cette position, le poussoir et en particulier sa bille d'extrémité 114 est repoussé dans le trou radial 102 vers le doigt de solidarisation par la portion la plus haute de la surface de came portée par la rampe 106. Le poussoir dont le ressort 110 a un coefficient de raideur élevé repousse la bille 108 formant organe de substitution de l'extrémité du doigt de solidarisation à l'intérieur du trou radial 76 du deuxième organe d'accouplement 52. Ainsi, cet organe de substitution interdit à l'extrémité 78 du doigt de solidarisation 68 de pénétrer dans le trou radial 76 et maintient le doigt de solidarisation 68 escamoté à l'intérieur du premier organe d'accouplement 40.In this position, the pusher and in particular its end ball 114 is pushed back into the radial hole 102 towards the securing finger by the highest portion of the cam surface carried by the ramp 106. The pusher whose spring 110 has a high stiffness coefficient pushes the ball 108 forming a substitution member of the end of the securing finger inside the radial hole 76 of the second coupling member 52. Thus, this substitution member prohibited at the end 78 of the joining finger 68 to penetrate into the radial hole 76 and keeps the joining finger 68 retracted inside the first coupling member 40.

Si, lors de la rotation de la bague 104, le trou 102 de l'embase 82 et le trou radial 76 du deuxième organe d'accouplement 52 ne sont pas correctement alignés, en raison par exemple d'un défaut de retour de ce dernier à sa position imposée par le ressort de rappel 124, la bille 108 ne peut pas pénétrer dans le trou radial 76. Sous l'effet de la poussée de la surface de came de la rampe 106, le ressort 110 du poussoir se comprime alors, permettant ainsi à la bille 114 de suivre la surface de came sans que le moteur 120 et les divers moyens mécaniques d'actionnement du poussoir associés ne soient détériorés. L'engagement de la bille 108 dans le trou radial 76 a lieu sous la poussée du ressort 110 dès que le deuxième organe d'accouplement 52 est correctement positionné dans l'alésage 80 de l'embase 82.If, during the rotation of the ring 104, the hole 102 of the base 82 and the radial hole 76 of the second coupling member 52 are not correctly aligned, due for example to a return defect of the latter in its position imposed by the return spring 124, the ball 108 cannot penetrate the radial hole 76. Under the effect of the thrust of the cam surface of the ramp 106, the spring 110 of the plunger then compresses, thus allowing the ball 114 to follow the cam surface without the motor 120 and the various mechanical means of actuation of the associated pusher being damaged. The engagement of the ball 108 in the radial hole 76 takes place under the thrust of the spring 110 as soon as the second coupling member 52 is correctly positioned in the bore 80 of the base 82.

Lorsque le doigt de solidarisation 68 est maintenu escamoté totalement dans le premier organe d'accouplement 40, ce dernier est alors libre de tourner à l'intérieur du trou borgne 64 du deuxième organe d'accouplement 52 puisque l'extrémité 78 du doigt de solidarisation 68 n'est plus en position de solidarisation. De même, le deuxième organe d'accouplement 52 est libre de tourner dans l'alésage 80 de l'embase 82, ce dernier entraînant dans sa rotation la bille 108 formant organe de substitution, mais il n'entraîne pas avec lui le premier organe d'accouplement 40 qui reste immobile.When the securing finger 68 is kept fully retracted in the first coupling member 40, the latter is then free to rotate inside the blind hole 64 of the second coupling member 52 since the end 78 of the securing finger 68 is no longer in the secured position. Similarly, the second coupling member 52 is free to rotate in the bore 80 of the base 82, the latter driving in its rotation the ball 108 forming a replacement member, but it does not carry with it the first member coupling 40 which remains stationary.

On conçoit que dans cet état de fonctionnement, le dispositif d'accouplement débrayable 14 assure la désolidarisation des deux tiges 8 et 16 et donc interdit la commande du pêne demi-tour 6 de la serrure depuis la béquille d'actionnement extérieure 18 liée à la tige 16. La commande du pêne demi-tour 6 est seulement possible depuis la béquille intérieure 10.It is understood that in this operating state, the disengageable coupling device 14 ensures the separation of the two rods 8 and 16 and therefore prohibits the control of the latch bolt 6 of the lock from the external actuating stand 18 linked to the rod 16. The control of the latch bolt 6 is only possible from the interior stand 10.

Pour établir de nouveau la solidarisation entre les deux tiges, la composition d'un code approprié sur le clavier à touches 28 permet le pilotage du moteur 120 par le dispositif de pilotage 122, de telle manière que celui-ci entraîne en rotation la bague 104 dans le sens des aiguilles d'une montre jusqu'à une position correspondant à celle représentée sur les figures 2 et 3. Dans cette position, le pion de blocage 107 vient en contact avec la paroi latérale de la partie en saillie 100 du flasque 94 limitant ainsi la course de la bague 104. L'extrémité 78 du doigt de solidarisation 68 est alors à nouveau reçue dans le trou radial 76, alors que l'organe de substitution formé par la bille 108 est escamoté à l'extrémité du trou radial 102 de l'embase 82.To re-establish the connection between the two rods, the composition of an appropriate code on the keypad 28 allows the motor 120 to be controlled by the control device 122, so that the latter rotates the ring 104 clockwise to a position corresponding to that shown on the Figures 2 and 3. In this position, the locking pin 107 comes into contact with the side wall of the projecting part 100 of the flange 94 thus limiting the stroke of the ring 104. The end 78 of the securing finger 68 is then again received in the radial hole 76, while the substitution member formed by the ball 108 is retracted at the end of the radial hole 102 of the base 82.

On conçoit qu'un tel dispositif permet une liaison d'une grande résistance entre les premier et deuxième organes d'accouplement et ainsi une grande solidité du dispositif.It is understood that such a device allows a connection of great resistance between the first and second coupling members and thus a high strength of the device.

De même, aucun organe de blocage n'étant mis en oeuvre pour interdire l'ouverture de la serrure depuis la béquille extérieure lorsque le dispositif d'accouplement est en position débrayée, un tel dispositif ne peut être forcé par application d'une force excessive sur la béquille extérieure puisque celle-ci est rendue folle et que toute action sur celle-ci est sans effet pour l'ouverture de la serrure.Likewise, since no locking member is used to prevent the opening of the lock from the outside stand when the coupling device is in the disengaged position, such a device cannot be forced by applying excessive force. on the outside stand since it is made crazy and any action on it has no effect for opening the lock.
