Description

La présente invention concerne les systèmes de commande des dispositifs de déverrouillage de secours pour des portes palières de gaine d'ascenseur.The present invention relates to control systems for emergency unlocking devices for landing hoist landing doors.

Afin de permettre l'ouverture d'urgence d'une porte palière d'ascenseur, il est connu de placer sur l'ouvrant ou le dormant de cette porte palière, un dispositif de déverrouillage de secours. Ce dispositif de déverrouillage de secours est généralement actionné au moyen d'une clef telle qu'un triangle que tous les services de secours possèdent. Le logement réceptionnant cette clef est localisé en un emplacement accessible aussi bien aux services de secours, qu'à n'importe quel utilisateur et donc à des utilisateurs malveillants.In order to allow emergency opening of an elevator landing door, it is known to place an emergency unlocking device on the opening or the frame of this landing door. This emergency unlocking device is generally actuated by means of a key such as a triangle that all the emergency services have. The accommodation receiving this key is located in a location accessible both to the emergency services and to any user and therefore to malicious users.

Par conséquent, même si de tels dispositifs donnent entièrement satisfaction quant au déverrouillage de secours, ils peuvent être vandalisés de sorte qu'un utilisateur malveillant peut déverrouiller la porte palière de la gaine d'ascenseur sans que la cabine d'ascenseur soit présente en arrière de la porte. Un utilisateur non averti de l'absence de la cabine peut ainsi ouvrir la porte et chuter dans la gaine d'ascenseur vide. Ces dispositifs entraînent donc malheureusement de nombreux accidents par malveillance.Therefore, even if such devices are entirely satisfactory with regard to emergency unlocking, they can be vandalized so that a malicious user can unlock the landing door of the elevator shaft without the elevator car being present behind Door. A user not informed of the absence of the car can thus open the door and fall into the empty elevator shaft. These devices therefore unfortunately lead to numerous malicious accidents.

La présente invention a donc pour but de remédier aux inconvénients précités en fournissant des moyens qui permettent d'éviter l'utilisation malveillante d'un dispositif de déverrouillage de secours.The present invention therefore aims to remedy the aforementioned drawbacks by providing means which make it possible to avoid the malicious use of an emergency unlocking device.

A cet effet, selon l'invention, il est fourni un système de commande d'un dispositif de déverrouillage de secours pour porte palière de gaine d'ascenseur essentiellement caractérisé en ce qu'il comprend :

  • un organe d'entraînement destiné à être relié au dispositif de déverrouillage de secours, et qui est mobile entre une position de repos et une position active pour entraîner le dispositif de déverrouillage entre respectivement une position de verrouillage de la porte palière et une position de déverrouillage de cette porte,
  • un doigt rotatif qui est destiné à être entraîné en rotation par une clef de manoeuvre extérieure au système,
  • des moyens de sélection pour sélectivement permettre la mise en prise du doigt rotatif et de l'organe d'entraînement, et qui sont mobiles entre une première position dans laquelle le doigt rotatif est libre en rotation par rapport à l'organe d'entraînement et une deuxième position dans laquelle le doigt rotatif et l'organe d'entraînement sont solidaires en rotation, et
  • des moyens de commande du déplacement des moyens de sélection entre les première et deuxième positions.
To this end, according to the invention, there is provided a system for controlling an emergency unlocking device for an elevator shaft landing door, essentially characterized in that it comprises:
  • a drive member intended to be connected to the emergency unlocking device, and which is movable between a rest position and an active position to drive the unlocking device respectively between a locking position of the landing door and an unlocking position from this door,
  • a rotary finger which is intended to be driven in rotation by an operating key external to the system,
  • selection means for selectively allowing the engagement of the rotary finger and the drive member, and which are movable between a first position in which the rotary finger is free to rotate relative to the drive member and a second position in which the rotary finger and the drive member are integral in rotation, and
  • means for controlling the movement of the selection means between the first and second positions.

Ainsi, grâce à ces dispositions, seuls les services de secours ou des personnes autorisées peuvent actionner les moyens de commande du déplacement des moyens de sélection afin de pouvoir mettre en prise, au moyen de leur clef de manoeuvre, le doigt rotatif avec l'organe d'entraînement qui actionne le dispositif de déverrouillage de secours pour déverrouiller la porte. Même si une personne non autorisée possède une clef de manoeuvre, le doigt rotatif étant monté fou lorsque les moyens de sélection sont dans leur première position, le dispositif de déverrouillage de secours ne pourra pas être actionné. De plus, puisque le doigt rotatif est monté fou, il n'offre pas de résistance mécanique et ne peut donc pas être forcé par vandalisme. De même, les moyens de sélection étant inaccessibles, ils ne pourront pas être forcés.Thus, thanks to these provisions, only the emergency services or authorized persons can actuate the means for controlling the movement of the selection means in order to be able to engage, by means of their operating key, the rotary finger with the member. drive which activates the emergency unlocking device to unlock the door. Even if an unauthorized person has an operating key, the rotary finger being mounted idly when the selection means are in their first position, the emergency unlocking device cannot be actuated. In addition, since the rotary finger is mounted idly, it does not offer mechanical resistance and therefore cannot be forced by vandalism. Likewise, since the selection means are inaccessible, they cannot be forced.

De préférence, l'organe d'entraînement et le doigt rotatif forment un dispositif à crabot.Preferably, the drive member and the rotary finger form a dog device.

Dans un mode préféré de réalisation, le doigt rotatif et l'organe de commande sont mobiles en rotation autour d'un même axe et sont alignés suivant cet axe, le doigt rotatif étant en outre déplaçable en translation suivant ledit axe.In a preferred embodiment, the rotary finger and the control member are movable in rotation about the same axis and are aligned along this axis, the rotary finger also being displaceable in translation along said axis.

En variante, les moyens de sélection comprennent une fourche mobile transversalement par rapport au dispositif à crabot entre la première position dans laquelle elle est interposée entre le doigt rotatif et l'organe d'entraînement et la deuxième position dans laquelle elle est dégagée du dispositif à crabot.As a variant, the selection means comprise a fork movable transversely with respect to the clutch device between the first position in which it is interposed between the rotary finger and the drive member and the second position in which it is released from the device to dog.

De préférence, les moyens de sélection comprennent en outre des moyens de blocage qui coopèrent, dans la première position des moyens de sélection, avec l'organe d'entraînement pour bloquer la rotation de l'organe d'entraînement. Le dispositif de déverrouillage de secours est ainsi bloqué en position de verrouillage.Preferably, the selection means further comprises locking means which cooperate, in the first position of the selection means, with the drive member to block the rotation of the drive member. The emergency unlocking device is thus locked in the locked position.

Encore de préférence, le doigt rotatif comprend un pignon à denture extérieure et l'organe d'entraînement comprend une couronne à denture intérieure située en regard du pignon.More preferably, the rotary finger comprises a pinion with external teeth and the drive member comprises a crown with internal teeth situated opposite the pinion.

Selon encore une autre caractéristique de l'invention, la fourche délimite un logement dans lequel le pignon du doigt rotatif pénètre lorsque la fourche est dans sa première position, la dimension de la fourche suivant ledit axe étant au moins égale à celle du pignon.According to yet another characteristic of the invention, the fork delimits a housing in which the pinion of the rotary finger penetrates when the fork is in its first position, the dimension of the fork along said axis being at least equal to that of the pinion.

Avantageusement, le système comprend en outre un ressort de compression qui s'étend suivant l'axe du dispositif à crabot et qui est interposé entre le doigt rotatif et l'organe d'entraînement pour écarter le pignon et la couronne d'un espace au moins égal à la dimension de la fourche.Advantageously, the system further comprises a compression spring which extends along the axis of the dog clutch and which is interposed between the rotary finger and the drive member to separate the pinion and the crown from a space at the less equal to the size of the fork.

Dans une autre variante, les moyens de commande de la fourche comprennent un électro-aimant dont l'alimentation en courant électrique est commandée à distance et provoque le déplacement de la fourche vers sa deuxième position.In another variant, the control means of the fork comprise an electromagnet whose supply of electric current is remotely controlled and causes the displacement of the fork towards its second position.

Avantageusement, les moyens de blocage comprennent une encoche ménagée dans la fourche et qui est destinée à coopérer avec un ergot porté par l'organe d'entraînement.Advantageously, the blocking means comprise a notch formed in the fork and which is intended to cooperate with a lug carried by the drive member.

Encore de préférence, le système comprend en outre un palier dont une première extrémité immobilise axialement l'organe d'entraînement et dont une deuxième extrémité loge à coulissement et en rotation le doigt rotatif, le palier comprenant en outre une lumière dans laquelle la fourche est déplaçable transversalement au palier.More preferably, the system further comprises a bearing, a first end of which axially immobilizes the drive member and a second end of which houses the rotary finger sliding and rotating, the bearing further comprising a slot in which the fork is movable transversely to the bearing.

Avantageusement, l'organe d'entraînement est monté solidaire en rotation d'une bielle de commande d'un pêne pour porte battante de gaine d'ascenseur.Advantageously, the drive member is mounted for rotation with a control rod for a bolt for a swing door of the elevator shaft.

En variante, l'organe d'entraînement est relié à un câble de commande d'une tringlerie pour porte coulissante de gaine d'ascenseur.As a variant, the drive member is connected to a control cable for a linkage for an elevator shaft sliding door.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant à titre d'exemple non limitatif une forme de réalisation préférentielle d'un système de commande selon l'invention.In any case, the invention will be clearly understood with the aid of the description which follows with reference to the appended schematic drawing showing by way of nonlimiting example a preferred embodiment of a control system according to the invention.

La figure 1 est une vue en perspective de l'ensemble du dispositif de déverrouillage de secours et du système de commande, ce dispositif étant installé sur le dormant d'une porte palière battante de gaine d'ascenseur, la clef de manoeuvre étant prête à être insérée dans le système de commande.FIG. 1 is a perspective view of the whole of the emergency unlocking device and of the control system, this device being installed on the frame of a swinging landing door of the elevator shaft, the operating key being ready for be inserted into the control system.

Les figures 2 et 3 sont respectivement des vues en perspective et en plan du dispositif de déverrouillage équipées du système de commande selon la présente invention, les capots métalliques ayant été retirés.Figures 2 and 3 are respectively perspective and plan views of the unlocking device equipped with the control system according to the present invention, the metal covers having been removed.

Les figures 4 à 7 sont respectivement des vues en perspective éclatée, en perpective arrière et avant, et en coupe longitudinale du système de commande de la figure 2.FIGS. 4 to 7 are respectively exploded perspective views, rear and front perspective, and in longitudinal section of the control system of FIG. 2.

La figure 8 est vue en perspective éclatée d'une première variante du système de commande.Figure 8 is an exploded perspective view of a first variant of the control system.

Les figures 9 et 10 représentent une deuxième variante du système de commande selon la présente invention.Figures 9 and 10 show a second variant of the control system according to the present invention.

Le dispositif de déverrouillage 1 représenté aux figures 1 à 3 est destiné à permettre le déverrouillage de secours d'une porte palière à battant pour une gaine d'ascenseur. Dans le cas présent, ce dispositif est monté dans le dormant 2 de la porte à battant (non représentée). On comprend bien entendu qu'en variante, ce dispositif pourrait être monté sur l'ouvrant de la porte palière.The unlocking device 1 shown in Figures 1 to 3 is intended to allow emergency unlocking of a swing landing door for an elevator shaft. In this case, this device is mounted in the frame 2 of the swing door (not shown). It is understood of course that, as a variant, this device could be mounted on the opening of the landing door.

Les dispositifs de déverrouillage de secours pour porte d'ascenseur sont largement connus et ne sont pas ici décrits en détail. On peut simplement rappeler, pour mémoire, que le dispositif de déverrouillage 1 est destiné à agir sur un pêne 5 destiné à être engagé dans ou désengagé hors d'une gâche (non représentée) complémentaire portée par le battant de la porte palière. Ce pêne 5 a généralement un mouvement transversal par rapport à la direction X-X selon laquelle s'étend le dormant 2 de la porte.Emergency unlocking devices for an elevator door are widely known and are not described here in detail. It can simply be recalled, for the record, that the unlocking device 1 is intended to act on a bolt 5 intended to be engaged in or disengaged from a keeper (not shown) complementary carried by the leaf of the landing door. This bolt 5 generally has a transverse movement relative to the direction X-X in which the frame 2 of the door extends.

Le dispositif de déverrouillage de secours 1 comprend de manière connue en soi, un palonnier 7 qui comprend une tête 8 et au moins une branche supérieure 9. Dans les dispositifs de déverrouillage connus, la tête 8 possède une forme complémentaire de celle d'une clef de manoeuvre 10 utilisée par les services de secours ou tout autre personne habilitée à déverrouiller la porte en cas d'urgence.The emergency unlocking device 1 comprises, in a manner known per se, a lifter 7 which comprises a head 8 and at least one upper branch 9. In known unlocking devices, the head 8 has a shape complementary to that of a key button 10 used by the emergency services or any other person authorized to unlock the door in the event of an emergency.

Par l'intermédiaire de la clef de manoeuvre 10, la branche supérieure 9 du dispositif de déverrouillage de secours 1 est entraînée en rotation parallèlement au plan de la porte, entre une position de verrouillage de cette porte dans laquelle le pêne 5 est en saillie (tel que représenté aux figures 1 à 3) pour pénétrer dans la gâche de la porte, et une position de déverrouillage de cette porte dans laquelle le pêne 5 est en retrait à l'intérieur du dormant de la porte pour libérer l'ouvrant de cette porte.By means of the operating key 10, the upper branch 9 of the emergency unlocking device 1 is rotated parallel to the plane of the door, between a locking position of this door in which the bolt 5 is projecting ( as shown in Figures 1 to 3) to enter the keeper of the door, and an unlocking position of this door in which the bolt 5 is recessed inside the frame of the door to release the door from this door.

Selon la présente invention, un système de commande 12 est interposé entre la clef de manoeuvre 10 et le dispositif de déverrouillage de secours 1. Ce système de commande 12 est plus particulièrement représenté aux figures 4 à 7. Le système 12 possède un organe d'entraînement 13 qui est destiné à être relié au dispositif de déverrouillage de secours 1, et qui est mobile entre une position de repos et une position active pour entraîner ce dispositif 1 entre respectivement les positions de verrouillage et de déverrouillage de la porte.According to the present invention, a control system 12 is interposed between the operating key 10 and the emergency unlocking device 1. This control system 12 is more particularly shown in Figures 4 to 7. The system 12 has a drive member 13 which is intended to be connected to the emergency unlocking device 1, and which is movable between a rest position and an active position to drive this device 1 between respectively door locking and unlocking positions.

Le système de commande 12 possède en outre un doigt rotatif 14 qui est destiné à être entraîné en rotation par la clef de manoeuvre 10, ainsi que des moyens de sélection 15 pour sélectivement permettre la mise en prise du doigt rotatif 14 et de l'organe d'entraînement 13, et qui sont mobiles entre une première position dans laquelle le doigt rotatif 14 est libre en rotation par rapport à l'organe d'entraînement 13 et une deuxième position dans laquelle le doigt rotatif 14 et l'organe d'entraînement sont solidaires en rotation.The control system 12 also has a rotary finger 14 which is intended to be driven in rotation by the operating key 10, as well as selection means 15 to selectively allow the engagement of the rotary finger 14 and the member. drive 13, and which are movable between a first position in which the rotary finger 14 is free to rotate relative to the drive member 13 and a second position in which the rotary finger 14 and the drive member are integral in rotation.

Selon une autre caractéristique essentielle de l'invention, le système 12 possède en outre des moyens de commande 16 pour déplacer les moyens de sélection 15 entre les première et deuxième positions.According to another essential characteristic of the invention, the system 12 also has control means 16 for moving the selection means 15 between the first and second positions.

Plus particulièrement, l'organe d'entraînement 13 est solidaire en rotation de la tête 8 du palonnier 7 et le doigt rotatif 14 possède une face avant 11 tournée vers l'extérieur du dormant 2 de la porte qui est de forme complémentaire à celle de la clef 10 de manoeuvre.

This shape can be triangular, or even polygonal.

Selon une autre caractéristique de l'invention, l'organe d'entraînement 13 et le doigt rotatif 14 forment un dispositif à crabot d'axe Y-Y perpendiculaire à l'axe X-X. L'organe 13 et le doigt 14 sont ainsi mobiles en rotation autour d'un même axe et sont alignés suivant cet axe.According to another characteristic of the invention, the drive member 13 and the rotary finger 14 form a dog clutch device of axis Y-Y perpendicular to the axis X-X. The member 13 and the finger 14 are thus movable in rotation about the same axis and are aligned along this axis.

En position de repos, c'est-à-dire lorsque le dispositif de déverrouillage de secours n'est pas actionné, le doigt 14 est monté fou de sorte que la rotation du doigt 14 n'entraîne pas en rotation l'organe 13.In the rest position, that is to say when the emergency unlocking device is not actuated, the finger 14 is mounted idly so that the rotation of the finger 14 does not cause the member 13 to rotate.

A cet effet, les moyens de sélection 15 sont interposés entre le doigt 14 et l'organe d'entraînement 13 pour interdire la coopération par engrenage du doigt 14 et de l'organe 13.To this end, the selection means 15 are interposed between the finger 14 and the drive member 13 to prohibit the cooperation by gear of the finger 14 and the member 13.

La face arrière 17 (tournée à l'opposé de la face avant 11) du doigt 14 est munie d'un pignon à denture extérieure 18 tandis que l'organe d'entraînement 13 possède une couronne à-denture intérieure 19 située en regard du pignon 18 en étant complémentaire de ce pignon pour coopérer sélectivement.The rear face 17 (facing away from the front face 11) of the finger 14 is provided with a pinion with external toothing 18 while the drive member 13 has an internal toothed crown 19 situated opposite the pinion 18 being complementary to this pinion to cooperate selectively.

Le pignon 18 et la couronne 19 sont de même axe et sont centrés sur l'axe Y-Y.The pinion 18 and the crown 19 are of the same axis and are centered on the axis Y-Y.

Le doigt 14 et l'organe 13 sont sollicités l'un à l'encontre de l'autre par un ressort de compression 20 interposé entre les deux faces en regard du doigt 14 et de l'organe 13 qui portent respectivement le pignon 18 et la couronne 19. Ainsi, le ressort de compression 20 est logé dans un alésage 21 qui débouche sur la face arrière 17 du doigt 14 et est en butée contre un ergot 22 qui est en saillie à l'intérieur de la couronne 19, à partir de l'organe 13. En variante, le ressort de compression peut être remplacé par un aimant qui repousse le doigt et l'organe d'entraînement l'un à l'encontre de l'autre par répulsion magnétique.The finger 14 and the member 13 are biased against each other by a compression spring 20 interposed between the two opposite faces of the finger 14 and the member 13 which respectively carry the pinion 18 and the crown 19. Thus, the compression spring 20 is housed in a bore 21 which opens on the rear face 17 of the finger 14 and is in abutment against a lug 22 which protrudes inside the crown 19, from of the member 13. As a variant, the compression spring can be replaced by a magnet which repels the finger and the drive member one against the other by magnetic repulsion.

Le doigt 14 est ainsi non seulement mobile en rotation autour de l'axe Y-Y, mais également est monté déplaçable en translation selon cet axe à l'intérieur d'un palier 25. Une première extrémité 26 ou extrémité avant de ce palier est en appui contre le dormant 2 de la porte et une deuxième extrémité 27 ou extrémité arrière de ce palier immobilise axialement l'organe d'entraînement 13 tout en permettant la rotation de cet organe autour de l'axe Y-Y.The finger 14 is thus not only movable in rotation about the axis YY, but also is mounted displaceable in translation along this axis inside a bearing 25. A first end 26 or front end of this bearing is supported against the frame 2 of the door and a second end 27 or rear end of this bearing axially immobilizes the drive member 13 while allowing the rotation of this member around the axis YY.

Le ressort de compression 20 permet d'écarter le doigt 14 et l'organe d'entraînement 13 en libérant un espace dans lequel les moyens de sélection 15 pénètrent, lorsque le système de déverrouillage 1 ne doit pas être actionné, pour être interposés entre le doigt 14 et l'organe 13.The compression spring 20 makes it possible to separate the finger 14 and the drive member 13 by freeing up a space in which the selection means 15 penetrate, when the unlocking system 1 must not be actuated, to be interposed between the finger 14 and organ 13.

A cet effet, les moyens de sélection 15 comprennent une fourche 30 déplaçable en translation selon l'axe X-X, parallèlement à la direction de la double flèche F (figure 7), et qui définit un logement 31 dans lequel le pignon 18 pénètre lorsque la fourche 30 est interposée entre le doigt 14 et l'organe d'entraînement 13. La fourche 30 s'étend transversalement au palier 25, en étant extérieure à celui-ci, et pénètre à l'intérieur de ce palier au travers d'une ouverture 32 pour atteindre le pignon 18.To this end, the selection means 15 comprise a fork 30 movable in translation along the axis XX, parallel to the direction of the double arrow F (FIG. 7), and which defines a housing 31 in which the pinion 18 penetrates when the fork 30 is interposed between the finger 14 and the drive member 13. The fork 30 extends transversely to the bearing 25, being external to the latter, and penetrates inside this bearing through a opening 32 to reach the pinion 18.

Dans la variante représentée à la figure 8, les moyens de sélection 15 comprennent en outre des moyens de blocage en rotation 37 de l'organe d'entraînement 13 qui coopèrent avec cet organe 37 lorsque les moyens de sélection sont dans la première position. Les moyens de blocage comprennent une encoche 37 située dans le fond de la fourche 31 et l'organe d'entraînement 13 possède un ergot 38 qui fait saillie selon l'axe Y-Y à partir de la couronne 19. Cet ergot pénètre dans l'encoche 37 lorsque la fourche 30 est dans la première position dans laquelle le doigt 14 est monté fou. Le dispositif de déverrouillage de secours est alors bloqué en position de verrouillage. On comprend que les moyens de blocage 37 peuvent également prendre la forme de deux méplats portés par l'organe 13 destinés à coopérer avec des formes complémentaires de la fourche 30.In the variant shown in Figure 8, the selection means 15 further comprises means for locking in rotation 37 of the drive member 13 which cooperate with this member 37 when the selection means are in the first position. The locking means comprise a notch 37 located in the bottom of the fork 31 and the drive member 13 has a lug 38 which projects along the axis YY from the crown 19. This lug penetrates into the notch 37 when the fork 30 is in the first position in which the finger 14 is mounted mad. The emergency unlocking device is then locked in the locked position. It is understood that the locking means 37 can also take the form of two flats carried by the member 13 intended to cooperate with complementary shapes of the fork 30.

Le mouvement de translation en va et vient de la fourche 30 est commandé par les moyens de commande 16 qui peuvent par exemple être un électro-aimant.The translational movement back and forth from the fork 30 is controlled by the control means 16 which may for example be an electromagnet.

La fourche 30 est mobile entre une première position dans laquelle elle est interposée entre le doigt 14 et l'organe 13 tel que représenté aux figures 5 à 7, et une deuxième position dans laquelle l'électro-aimant a entraîné la fourche 30 vers le bas pour la dégager du doigt 14 et ainsi permettre de repousser le doigt 14 en direction de l'organe 13, à l'encontre de la force du ressort de compression 20.The fork 30 is movable between a first position in which it is interposed between the finger 14 and the member 13 as shown in FIGS. 5 to 7, and a second position in which the electromagnet has driven the fork 30 towards the bottom to release it from finger 14 and thus allow finger 14 to be pushed back towards the member 13, against the force of the compression spring 20.

La fourche 30 est sollicitée par un autre ressort de compression 35 vers sa première position. L'alimentation en courant électrique de l'électroaimant 16 provoque le déplacement de la fourche 30 depuis sa première position vers sa deuxième position, à l'encontre de la force du ressort 35.The fork 30 is biased by another compression spring 35 towards its first position. The supply of electric current to the electromagnet 16 causes the fork 30 to move from its first position to its second position, against the force of the spring 35.

L'alimentation en courant électrique de l'électro-aimant 16 est commandée à distance du système 1, en un emplacement distinct de la clef de manoeuvre 10. Cet emplacement est de préférence non apparent pour un utilisateur non averti. Il est par exemple situé dans le local où est implanté le moteur d'entraînement de la cabine d'ascenseur.The supply of electric current to the electromagnet 16 is controlled remotely from the system 1, at a location separate from the operating key 10. This location is preferably not apparent to an untrained user. It is for example located in the room where the drive motor of the elevator car is located.

Lorsque la fourche 30 est dans sa deuxième position ou position effacée, la clef de manoeuvre 10 peut d'une part entraîner le doigt 14 en translation selon l'axe Y-Y pour venir coopérer avec l'organe 13, mais également en rotation pour entraîner en rotation l'organe 13 entre sa position de verrouillage de la porte palière et sa position de déverrouillage de cette porte.When the fork 30 is in its second position or erased position, the operating key 10 can on the one hand drive the finger 14 in translation along the axis YY to come cooperate with the member 13, but also in rotation to drive in rotation of the member 13 between its locking position of the landing door and its unlocking position of this door.

Au contraire, lorsque la fourche 30 est dans sa première position, le doigt 14 ne peut pas coopérer avec l'organe 13. Le doigt est alors monté fou de sorte que toute action malveillante sur ce doigt n'a pas de conséquence sur le déblocage intempestif de la porte puisque l'organe de manoeuvre reste immobile, n'entraînant donc pas le dispositif de déverrouillage de secours.On the contrary, when the fork 30 is in its first position, the finger 14 cannot cooperate with the member 13. The finger is then mounted mad so that any malicious action on this finger has no consequence on the release. untimely door since the operating member remains stationary, therefore not causing the emergency unlocking device.

Dans la variante représentée aux figures 9 et 10, le système de commande 12 selon la présente invention comporte les mêmes parties constitutives, l'organe d'entraînement n'est toutefois plus solidaire en rotation de la tête 8 du palonnier 7, un câble 40 logé dans une enveloppe 41 est entraîné à coulissement par la rotation de l'organe 13. Ce câble 40 est destiné à être relié à une tringlerie (non représentée) pour une porte coulissante de gaine d'ascenseur. Le fonctionnement du système de commande 12 est identique à celui décrit précédemment.In the variant shown in Figures 9 and 10, the control system 12 according to the present invention comprises the same parts constitutive, the drive member is however no longer integral in rotation with the head 8 of the lifter 7, a cable 40 housed in an envelope 41 is slidably driven by the rotation of the member 13. This cable 40 is intended to be connected to a linkage (not shown) for a sliding elevator shaft door. The operation of the control system 12 is identical to that described above.

Comme il va de soi, l'invention ne se limite pas à la forme de réalisation préférentielle décrite ci-dessus à titre d'exemple non limitatif, elle en embrasse au contraire toutes les variantes de réalisation dans le cadre des revendications ci-après.It goes without saying that the invention is not limited to the preferred embodiment described above by way of nonlimiting example, on the contrary it embraces all the variant embodiments thereof within the scope of the claims below.
