Description

La présente invention concerne un appareil de signalisation, en particulier pour des besoins industriels, par exemple pour la signalisation de différents états de service et/ou de dérangement, avec des machines électriques, de préférence des machines automatiques, comprenant plusieurs, au moins deux transmetteurs de signal optique et/ou acoustique, qui sont disposés de façon sensiblement linéaire, juxtaposés et/ou superposés et sont reliés par des lignes d'énergie à une source d'énergie, les transmetteurs de signaux présentant chacun un boítier dans lequel sont disposés les récepteurs électriques pour générer un signal optique et/ou acoustique, par exemple des lampes, des boítiers disposés à côté étant reliés entre eux par un élément d'accouplement.The present invention relates to a signaling device, in particular for industrial needs, for example for signaling different states of service and / or fault, with electric machines, preferably automatic machines, comprising several, at least two transmitters optical and / or acoustic signal, which are arranged in a substantially linear fashion, juxtaposed and / or superimposed and are connected by energy lines to a source energy, signal transmitters each having a housing in which electrical receivers are arranged to generate an optical signal and / or acoustics, for example lamps, housings arranged next to each other being connected between them by a coupling element.

Des appareils de signalisation de ce type sont connus dans l'état actuel de la technique. Par exemple, DE 90 10 187 U1 dévoile un dispositif d'affichage optique, en particulier pour des besoins industriels, qui a un boítier creux et étiré en longueur avec au moins deux bandes longitudinales ou parties longitudinales, qui sont transparentes au moins partiellement. Dans ce boítier est insérée une construction porteuse de lampes, qui supporte au moins deux lampes, lesquelles sont affectées à des positions correspondantes dans les bandes du boítier et sont reliées de façon électrique à des branchements électriques disposés dans une zone d'extrémité de la construction porteuse. De plus, ce dispositif d'affichage déjà connu présente au moins un connecteur électrique, qui est relié à la zone d'extrémité citée de la construction porteuse de lampes et est disposé de façon à permettre la liaison électrique des lampes et des dispositifs de commutation disposés à l'extérieur du boítier. Le boítier comprend plusieurs parties disposées de façon linéaire, qui sont vissées entre elles. Pour le remplacement des lampes disposées dans les constructions porteuses de lampes, il est donc nécessaire que le boítier soit ouvert à une extrémité et que la construction porteuse de lampes soit sortie. L'inconvénient de ce dispositif déjà connu est qu'il est impossible d'avoir un écran pour la lumière entre les différentes parties du boítier, de sorte qu'on ne peut pas voir, en particulier à partir d'une grande distance, quelle lampe est allumée à l'intérieur de l'appareil. De plus, on doit remplacer l'ensemble de la construction porteuse de lampes en cas de défaillances dans celle-ci. Signaling devices of this type are known in the current state of the art. technical. For example, DE 90 10 187 U1 discloses an optical display device, especially for industrial needs, which has a hollow case and stretched in length with at least two longitudinal strips or longitudinal parts, which are at least partially transparent. In this case is inserted a construction lamp carrier, which supports at least two lamps, which are assigned to corresponding positions in the housing bands and are connected in a way electrical to electrical connections arranged in an end area of the load-bearing construction. In addition, this already known display device present at minus an electrical connector, which is connected to the cited end area of the lamp-carrying construction and is arranged to allow connection electric lamps and switching devices arranged outside the housing. The housing comprises several parts arranged in a linear fashion, which are screwed together. For the replacement of the lamps arranged in the lamp-carrying constructions, it is therefore necessary that the housing is open to one end and that the lamp-carrying construction is out. The downside of this device already known is that it is impossible to have a screen for the light between the different parts of the case, so that we can not see, especially at from a great distance, which lamp is lit inside the device. Of addition, the entire lamp-carrying structure must be replaced in the event of failures in it.

On connaít également par FR 2 517 021 un appareil de signalisation qui comprend plusieurs parties de boítier disposées de façon linéaire et superposées, dans lesquelles sont disposés des éléments conducteurs, de sorte que les différentes lampes peuvent être commandées dans les différentes parties de boítier au moyen d'un socle qui relie l'appareil à une source d'énergie. Cet appareil a fait ses preuves, mais présente des raccords à vis par lesquels les différentes parties du boítier sont reliées entre elles.We also know from FR 2 517 021 a signaling device which comprises several housing parts arranged in a linear fashion and superimposed, in which are arranged conductive elements, so that the different lamps can be ordered in the different parts of the housing by means a base that connects the device to an energy source. This device has proven itself, but has screw connections by which the different parts of the housing are interconnected.

Cet appareil de signalisation comprend plusieurs éléments lumineux identiques et superposés, qui comprennent chacun un capot transparent, lequel est fixé sur une cloison de séparation transversale, sur laquelle est logée une ampoule. On prévoit également des lignes d'alimentation traversant les éléments lumineux, dont les extrémités sont conçues comme des systèmes à contact pour des éléments lumineux voisins. La cloison de séparation présente des systèmes de raccord élastiques, qui, lorsqu'on tourne la cloison de séparation par rapport au capot cylindrique, s'engagent dans une position déterminée entre des épaulements de celui-ci. En dehors des deux lignes d'alimentation pour les lampes d'un élément lumineux, on prévoit d'autres lignes d'alimentation pour des éléments lumineux disposés au-dessus.
La liaison des éléments lumineux s'effectue par un premier système de liaison, le premier système de liaison comprenant des zones avec un pas en forme de vis, qui sont reliées à une couronne, laquelle est fixée sur la paroi de séparation avec une certaine élasticité axiale. En outre, on sait par cette publication antérieure réaliser les systèmes de liaison sous la forme de fermeture à baïonnette, fermeture à vis, fermeture mobile dans le sens radial ou également de fermeture à aspiration ou fermeture magnétique.Another signaling device is known from DE 22 11 801 B2. This signaling device comprises several identical and superimposed light elements, each of which comprises a transparent cover, which is fixed to a transverse partition, on which is housed a bulb. Supply lines are also provided passing through the light elements, the ends of which are designed as contact systems for neighboring light elements. The partition has elastic connection systems, which, when the partition is turned relative to the cylindrical cover, engage in a determined position between the shoulders of the latter. Apart from the two supply lines for the lamps of a light element, other supply lines are provided for light elements arranged above.
The connection of the light elements is carried out by a first connection system, the first connection system comprising zones with a screw-shaped pitch, which are connected to a crown, which is fixed to the partition wall with a certain elasticity axial. In addition, it is known from this previous publication to realize the connection systems in the form of bayonet closure, screw closure, movable closure in the radial direction or also of suction closure or magnetic closure.

Les parties de boítier superposées sont disposées entre un socle et un couvercle, le socle étant relié au couvercle par des tiges filetées et/ou des vis.Document FR 1 526 306 discloses a signaling device with several housing parts arranged superimposed, in each of which is inserted a lamp. The superimposed housing parts are arranged between a base and a cover, the base being connected to the cover by threaded rods and / or screws.

Le document DE 297 19 399 U décrit un appareil de signalisation à boítiers superposés reliés entre eux par des bagues d'accouplement, chaque bague étant liée à un premier boítier et ayant un évidement du type à baïonnette dans lequel s'engage une saillie correspondante prévue sur le second boítier pour assurer le couplage entre les deux boítiers. La liaison de la bague d'accouplement avec le premier boítier n'est pas définie de manière suffisamment rigoureuse.Document DE 297 19 399 U describes a signaling device with stacked boxes interconnected by coupling rings, each ring being linked to a first housing and having a bayonet type recess in which engages a corresponding projection provided on the second housing to ensure coupling between the two boxes. The connection of the coupling ring with the first housing is not sufficiently rigorously defined.

En partant de cet état de la technique, l'invention à pour objectif de créer un appareil de signalisation à boítiers couplés par des bagues à baïonnette, les bagues ayant des premiers évidements qui s'étendent en sens périphérique et coopèrent avec des pattes élastiques d'un premier boítier pour s'y fixer axialement tout en pouvant tourner, et au moins un évidement du type à baïonnette dans lequel s'engage une saillie correspondante d'un deuxième boítier, cet appareil devant être de conception simple et pouvant être monté essentiellement sans raccords vissés, tout en permettant de préférence l'exécution de tâches simplifiées de maintenance et d'extension, en particulier en ce qui concerne le remplacement de lampes défectueuses et/ou d'autres composants électriques et/ou électroniques, sans qu'il soit nécessaire d'effectuer un démontage pratiquement complet.Starting from this state of the art, the invention aims to create an apparatus signaling with housings coupled by bayonet rings, the rings having first recesses which extend in peripheral direction and cooperate with elastic tabs of a first housing to fix it axially while being able turn, and at least one bayonet type recess in which engages a corresponding projection of a second housing, this apparatus having to be of design simple and can be mounted essentially without screw connections, while preferably allowing the execution of simplified maintenance tasks and extension, in particular with regard to the replacement of lamps defective and / or other electrical and / or electronic components, without it it is necessary to carry out a practically complete disassembly.

La solution à ce problème prévoit qu'un tenon ou came du premier boítier est logé dans la bague d'accouplement de façon que celle-ci puisse tourner de façon limitée par rapport au boítier et que le premier évidement sert au logement d'un élément élastique conçu comme élément de verrouillage pour bloquer la rotation relative de la bague par rapport au premier boítier. Un dispositif de signalisation réalisé selon ce principe a en particulier l'avantage de permettre de séparer facilement l'un de l'autre les boítiers superposés et de bloquer la rotation relative de la bague d'accouplement par rapport au premier boítier.The solution to this problem provides that a tenon or cam of the first housing is housed in the coupling ring so that it can rotate in a limited way relative to the housing and that the first recess is used to house an element elastic designed as a locking element to block the relative rotation of the ring with respect to the first case. A signaling device produced according to this principle in particular has the advantage of allowing easy separation from one another the overlapping housings and blocking the relative rotation of the coupling ring compared to the first box.

Cette conception signale à la personne chargée de la manipulation le début et la fin de la rotation nécessaire de la bague d'accouplement pour séparer les boítiers voisins les uns des autres. Du reste, on évite de cette façon que le nouveau montage de boítiers voisins soit compliqué par de multiples essais de rotation.This design signals the start and end to the person handling it of the necessary rotation of the coupling ring to separate the housings neighbors of each other. Besides, this avoids that the new mounting of neighboring boxes is complicated by multiple rotation tests.

Selon une autre caractéristique de l'invention, le tenon du premier boítier est logé dans un deuxième évidement de la bague d'accouplement et dans ce deuxième évidement est disposée une came derrière laquelle le tenon peut être verrouillé. La came maintient le tenon du boítier avec la position d'ouverture dans une certaine position, de sorte qu'une torsion involontaire de la bague d'accouplement pendant le démontage ou le montage des boítiers voisins est indiquée de façon perceptible par une résistance qui est obtenue en raison du glissement de la came devant le tenon ou du tenon devant la came. De plus, la combinaison de la came et du tenon permet de fixer la bague d'accouplement dans sa position d'ouverture, de sorte que le montage de l'appareil de signalisation est sensiblement simplifié par le fait que la personne montant l'appareil de signalisation n'est pas obligée pour commencer de déplacer la bague d'accouplement dans la position correspondante et doit rechercher la position nécessaire par un examen visuel ou par différents essais.According to another characteristic of the invention, the post of the first housing is housed in a second recess in the coupling ring and in this second recess is arranged a cam behind which the tenon can be locked. The cam maintains the tenon of the case with the open position in a certain position, so that an involuntary twisting of the coupling ring during the disassembly or assembly of neighboring enclosures is clearly indicated by a resistance which is obtained due to the sliding of the cam in front of the tenon or the post in front of the cam. In addition, the combination of cam and tenon allows to fix the coupling ring in its open position, so that the mounting of the signaling device is significantly simplified by the fact that the person mounting the signaling device is not required to start move the coupling ring to the corresponding position and should search the necessary position by visual inspection or by various tests.

L'élément élastique peut faire partie d'un élément de verrouillage inséré dans un évidement correspondant situé dans le boítier et présenter une saillie d'arrêt sur l'un de ses côtés. Il est prévu ici que l'élément de verrouillage n'est pas relié au boítier, ce qui permet d'une part une fabrication avantageuse et simple du boítier avec l'élément de verrouillage séparé et d'autre part un déplacement limité de l'élément de verrouillage par rapport au boítier, afin de compenser des tolérances de fabrication entre la bague d'accouplement et le boítier. L'élément de verrouillage est logé de préférence de façon coulissante dans la direction de l'axe du boítier. Cette conception permet que l'élément du verrouillage puisse coulisser par rapport à la bague d'accouplement après l'avoir sorti de l'orifice d'arrêt, de sorte que l'élément de verrouillage est fixé dans sa position sortie derrière la bague d'accouplement et ne revient pas dans l'orifice d'arrêt après avoir enlevé un outil permettant la sortie de l'élément de verrouillage.The elastic element may be part of a locking element inserted in a corresponding recess located in the housing and have a stop projection on one on his side. It is provided here that the locking element is not connected to the housing, this which allows on the one hand an advantageous and simple manufacture of the housing with the element separate locking and on the other hand limited movement of the element locking relative to the housing, in order to compensate for manufacturing tolerances between the coupling ring and the housing. The locking element is housed in preferably sliding in the direction of the axis of the housing. This design allows the locking element to slide relative to the coupling ring after removing it from the stop hole, so that the lock is fixed in its extended position behind the coupling ring and does not not return to the stop hole after removing a tool allowing the exit of the locking element.

Il est également prévu que le premier évidement présente une surface inclinée s'étendant dans le sens d'axe longitudinal de la bague d'accouplement, qui sollicite l'élément de verrouillage avec une force dans le sens de l'axe longitudinal du boítier et que l'élément de verrouillage est logé de façon à pouvoir coulisser dans le sens axial du boítier. Cette surface inclinée sert à déplacer par rapport au boítier l'élément de verrouillage poussé dans le sens axial du boítier lors du verrouillage de la bague d'accouplement sur le boítier dans la position axiale nécessaire, de sorte que l'élément de verrouillage ou la lame élastique s'engage dans l'ouverture d'arrêt de la façon nécessaire et souhaitée. It is also expected that the first recess has an inclined surface extending in the longitudinal axis direction of the coupling ring, which urges the locking element with a force in the direction of the longitudinal axis of the housing and that the locking element is housed so that it can slide in the direction axial of the housing. This inclined surface is used to move the element relative to the housing. locking pushed in the axial direction of the housing when locking the ring coupling on the housing in the necessary axial position, so that the locking element or the elastic blade engages in the stop opening of the necessary and desired way.

Avec un autre mode de réalisation de l'invention, il est prévu que l'élément élastique présente deux positions d'arrêt espacées l'une de l'autre, dans lesquelles une came disposée sur le premier boítier peut s'engager, la première position d'arrêt étant disposée dans la zone d'une ouverture d'accès allant dans le sens de l'axe. La came du boítier est donc introduite dans l'ouverture d'accès de la bague qui va dans le sens de l'axe, la bague étant tournée ensuite par rapport au boítier. De cette façon, la came est amenée par l'élément élastique dans la deuxième position d'arrêt, dans laquelle la came s'appuie de tous les côtés de façon limitée sur les parois de la bague ou sur une surface de butée de l'élément élastique.
L'élément élastique est conçu de préférence comme une plaque sensiblement en forme de W. Les deux branches extérieures de la plaque en forme de W constituent les surfaces de butée des positions d'arrêt, de sorte que la branche extérieure de la plaque est disposée dans la zone de l'ouverture d'accès. Les branches disposées entre les deux branches extérieures de la plaque en forme de W forment un élément en forme de V, l'angle entre les deux branches étant sensiblement obtus, c'est-à-dire compris entre 90° et 180°. Ces deux branches permettent un déplacement élastique de l'élément, de sorte que la came peut être déplacée sur les deux surfaces de butée constituées par les branches extérieures de l'élément en forme de W.With another embodiment of the invention, it is provided that the elastic element has two stop positions spaced from one another, in which a cam disposed on the first housing can engage, the first stop position being arranged in the area of an access opening going in the direction of the axis. The cam of the housing is therefore introduced into the access opening of the ring which goes in the direction of the axis, the ring then being turned relative to the housing. In this way, the cam is brought by the elastic element into the second stop position, in which the cam rests on all sides in a limited manner on the walls of the ring or on a stop surface of the elastic element.
The elastic element is preferably designed as a substantially W-shaped plate. The two outer branches of the W-shaped plate constitute the abutment surfaces of the stop positions, so that the outer branch of the plate is arranged. in the area of the access opening. The branches arranged between the two outer branches of the W-shaped plate form a V-shaped element, the angle between the two branches being substantially obtuse, that is to say between 90 ° and 180 °. These two branches allow an elastic displacement of the element, so that the cam can be moved on the two abutment surfaces formed by the external branches of the W-shaped element.

Un appareil de signalisation représenté sur la figure 1 comprend plusieurs (ici 2) transmetteurs de signal 2 disposés de façon linéaire et superposée. Chaque transmetteur de signal 2 présente un boítier 3, dans lequel est disposé un récepteur électrique 4 pour la génération d'un signal optique et/ou acoustique.A signaling device shown in the Figure 1 includes several (here 2) transmitters signal 2 arranged linearly and superimposed. Each signal transmitter 2 has a box 3, in which an electrical receiver 4 is arranged for the generation of an optical and / or acoustic signal.

Chaque boítier comprend une partie de forme cylindrique avec une insertion 24, qui est disposée sur une extrémité du boítier 3 et forme dans la zone de son enveloppe un décrochement 25, dont le diamètre extérieur est plus faible que le diamètre extérieur du boítier 3. Sur ce décrochement 25, on peut poser un joint 16, qui assure l'étanchéité de 2 boítiers 3 voisins, de sorte qu'on évite une pénétration de la poussière et/ou de l'humidité dans le boítier.Each case includes a shape part cylindrical with an insert 24, which is arranged on one end of the housing 3 and forms in the sound area envelops a recess 25, the diameter of which outside is smaller than the outside diameter of the box 3. On this recess 25, we can put a seal 16, which seals 2 housings 3 neighbors, so that penetration of the dust and / or moisture in the housing.

Le boítier 3 est représenté de façon détaillée sur la figure 4. On peut voir que le boítier 3 présente sur une extrémité axiale trois cames 5 de conception trapézoïdale, qui débordent de l'enveloppe extérieure 6 du boítier 3. Les cames 5 sont réparties à intervalles réguliers sur l'enveloppe extérieure 6. En conséquence, ces cames 5 sont prévues avec un déport de 120° sur l'enveloppe extérieure 6.The housing 3 is shown in detail on Figure 4. We can see that the housing 3 presents on one axial end three cams 5 design trapezoidal, protruding from the outer casing 6 of the housing 3. The cams 5 are distributed at intervals regular on the outer envelope 6. Consequently, these cams 5 are provided with a 120 ° offset on the outer casing 6.

Le boítier 3 présente dans la zone de son extrémité axiale opposée à la came 5 une gorge 7, qui fait approximativement le tour de l'ensemble du boítier 3 et est interrompue par un évidement 8. L'évidement 8 sert à loger un élément de verrouillage 9 représenté sur la figure 6. En conséquence, l'évidement 8 est conçu comme une cavité sensiblement rectangulaire, qui présente dans sa zone centrale un creux cunéiforme vu en coupe.Box 3 present in the area of its end axial opposite to cam 5 a groove 7, which makes approximately the turn of the whole case 3 and is interrupted by a recess 8. The recess 8 serves to house a locking element 9 shown in the Figure 6. Consequently, the recess 8 is designed as a substantially rectangular cavity, which has in its central zone a cuneiform hollow seen in section.

D'autre part, le boítier 3 présente un dispositif d'affichage 10 de forme triangulaire, qui est dispose également dans l'enveloppe extérieure 6 et se situe entre deux cames 5.On the other hand, the housing 3 has a device display 10 of triangular shape, which is has also in the outer casing 6 and is located between two cams 5.

Dans la gorge 7 est insérée une bague 11 à base de matériau élastique, qui est donc réalisée de façon ouverte en fonction de la longueur de la gorge 7. La bague 11 relie le boítier 13 à un élément d'accouplement 27. L'élément d'accouplement 27 est représenté de façon détallée sur la figure 5 et est décrit ci-dessous.In the groove 7 is inserted a ring 11 based on elastic material, which is therefore made so open depending on the length of the groove 7. The ring 11 connects the housing 13 to an element coupling element 27. The coupling element 27 is shown in detail in Figure 5 and is described below.

Chaque élément d'accouplement 27 est conçu comme une bague. En conséquence, chaque élément d'accouplement 27 présente une enveloppe extérieure 28 et une enveloppe intérieure 29. Dans l'enveloppe intérieure 29 est disposée une gorge 30 qui fait pratiquement tout le tour et sert au logement de la bague 11. La gorge 30 à deux extrémités, entre lesquelles est disposé un premier évidement 31 allant dans le sens périphérique. L'évidement 31 est conçu en forme de L et a une ouverture dirigée vers un bord axial de l'élément d'accouplement 27. D'autre part, l'évidement 31 présente sur son extrémité disposée en face de l'ouverture 32 un orifice d'arrêt 33, qui englobe par rapport à l'évidement 31 l'épaisseur globale de l'élément d'accouplement 27, de sorte que l'orifice d'arrêt 33 est ouvert aussi bien en direction de l'enveloppe extérieure 28 qu'en direction de l'enveloppe intérieure 29.Each coupling element 27 is designed as a ring. Consequently, each element coupling 27 has an outer casing 28 and an inner envelope 29. In the envelope inner 29 is arranged a groove 30 which makes practically all around and is used to house the ring 11. The throat 30 at two ends, between which is disposed a first recess 31 going in the peripheral direction. The recess 31 is designed in L-shaped and has an opening directed towards an edge axial of the coupling element 27. On the other hand, the recess 31 present on its end arranged in face of the opening 32 a stop orifice 33, which includes with respect to the recess 31 the thickness overall of the coupling element 27, so that the stop orifice 33 is open both towards of the outer casing 28 only towards the inner envelope 29.

Un deuxième évidement allant dans le sens périphérique de l'élément d'accouplement 27 est disposé de façon diamétralement opposée au premier évidement 31 allant dans le sens périphérique de l'élément d'accouplement 27. De ce deuxième évidement, on peut voir sur la figure 5 uniquement une ouverture 34 qui est disposée dans le même sens que l'orifice 32 en direction de l'élément d'accouplement 27.A second recess going in the direction device of the coupling element 27 is arranged diametrically opposite to the first recess 31 going in the peripheral direction of the element of coupling 27. From this second recess, one can see in Figure 5 only an opening 34 which is arranged in the same direction as the hole 32 in direction of the coupling element 27.

L'élément d'accouplement 27 conçu comme une bague est relié au boítier 3 de façon à pouvoir pivoter avec lui par l'intermédiaire de la bague 11 insérée dans la gorge 30 de l'élément d'accouplement 27 d'une part et dans la gorge 7 du boítier 3 d'autre part. A cet effet, la bague 11 mise sous prétension est insérée dans la gorge 30 de l'élément d'accouplement 27. Au moyen d'un mandrin de montage de forme conique et non représenté plus en détail, qui est prévu sur le bord inférieur du boítier 3, la bague 11 est écartée dans la gorge 30 de l'élément d'accouplement 27 lors de la pose de l'élément d'accouplement 27 sur le boítier 3. Dès que la bague atteint la gorge 7 du boítier 3, la bague 11 s'enclenche sous l'effet de sa prétension dans cette gorge 7, de sorte que l'élément d'accouplement 27 est fixé par la bague 11 dans le sens axial sur le boítier 3 d'un transmetteur de signal 2.The coupling element 27 designed as a ring is connected to the housing 3 so as to be able to pivot with him through the ring 11 inserted in the groove 30 of the coupling element 27 on the one hand and in the groove 7 of the housing 3 on the other hand. To this end, the pre-tensioned ring 11 is inserted into the groove 30 of the coupling element 27. By means of a cone-shaped mounting mandrel, not shown in more detail, which is provided on the bottom edge of the case 3, the ring 11 is spread in the groove 30 of the coupling element 27 when fitting the coupling element 27 on the housing 3. As soon as the ring reaches the groove 7 of the housing 3, the ring 11 snaps under the effect of its pretension in this groove 7, so that the coupling element 27 is fixed by the ring 11 in the axial direction on the housing 3 of a signal transmitter 2.

En outre, l'élément d'accouplement 27 présente sur son enveloppe intérieure 29 des guides à baïonnette 35, qui peuvent être verrouillés avec les cames 5 d'un boítier voisin 3, de sorte que les boítiers voisins 3 sont reliés de façon fixe entre eux dans le sens axial. Les guides à baïonnette 35 sont également conçus en forme de L, mais l'ouverture disposée dans le sens axial de l'élément d'accouplement 27 est orientée dans le sens contraire aux directions des ouvertures 32 et 34. D'autre part, on peut voir que les guides à baïonnette 35 sont disposés dans une partie située au-dessous de la gorge 30, alors que l'évidement 31 et l'évidement relié à l'ouverture 34, qui sont encore décrits ci-dessous, sont disposés au-dessus de la gorge 30.In addition, the coupling element 27 present on its inner casing 29 of the bayonet guides 35, which can be locked with cams 5 of a neighboring housing 3, so that the neighboring housing 3 are fixedly connected to each other in the axial direction. The bayonet guides 35 are also designed in L shape, but the opening arranged in the direction axial of the coupling element 27 is oriented in the opposite direction to the directions of the openings 32 and 34. On the other hand, it can be seen that the guides to bayonet 35 are arranged in a part located below throat 30, while the recess 31 and the recess connected to the opening 34, which are still described below, are arranged above the throat 30.

L'ouverture 34 est reliée à un évidement 12 représenté sur les figures 10 à 15, qui est disposé dans le sens périphérique sur l'enveloppe intérieure 29 de l'élément d'accouplement 27. Sur une extrémité de l'évidement 12, il est prévu une saillie 13, qui subdivise l'évidement 12 en une partie plus grande et une partie plus petite. La saillie 13 agit conjointement avec une came 14 sur l'enveloppe extérieure 6 du boítier 3 de telle façon que la came 14 puisse être déplacée sur la saillie 13 et s'enclenche derrière la saillie 13 dans la partie plus courte de l'évidement 12, afin d'indiquer une position définie de l'élément d'accouplement 27 par rapport au boítier 3.The opening 34 is connected to a recess 12 shown in Figures 10 to 15, which is arranged in the peripheral direction on the inner envelope 29 of the coupling element 27. On one end of the recess 12, a projection 13 is provided, which subdivides the recess 12 into a larger part and a smaller part. The projection 13 acts together with a cam 14 on the casing outside 6 of the housing 3 so that the cam 14 can be moved on the projection 13 and snaps behind the projection 13 in the shorter part of the recess 12, in order to indicate a defined position of the coupling element 27 relative to the housing 3.

Sur la figure 6, on présente un élément de verrouillage 9, qui peut être inséré dans l'évidement 8, dans l'enveloppe extérieure 6 du boítier 3. L'élément de verrouillage 9 comprend quatre barrettes 15, 16, 17 et 18 disposées à angle droit les unes par rapport aux autres. Les barrettes 15, 16, 17 et 18 présentent une longueur sensiblement identique et délimitent une ouverture 19, dans laquelle est disposée une lame 20 élastique. La lame 20 élastique s'étend de la barrette 18 à l'ouverture 19, la lame élastique allant approximativement jusqu'à la barrette 15. La lame élastique déborde du plan déterminé par les barrettes 15, 16, 17 et 18 et présente une saillie d'arrêt 21.In Figure 6, an element of lock 9, which can be inserted into the recess 8, in the outer casing 6 of the housing 3. The locking element 9 comprises four bars 15, 16, 17 and 18 arranged at right angles to each other compared to others. Bars 15, 16, 17 and 18 have a substantially identical length and delimit an opening 19, in which is disposed an elastic blade 20. The elastic blade 20 extends from the bar 18 at the opening 19, the elastic blade going approximately to bar 15. The elastic blade extends beyond the plane determined by the bars 15, 16, 17 and 18 and has a projection stop 21.

D'autre part, l'élément de verrouillage 9 a un système de guidage 22 débordant sur le côté, qui est conçu comme une barrette et s'étend sur le bord extérieur de la barrette 16 dans le sens longitudinal de la barrette 18. Ce système de guidage 22 est guidé dans une ouverture correspondante de l'évidement 8.On the other hand, the locking element 9 has a guide system 22 projecting from the side, which is designed as a bar and extends over the edge outside of the bar 16 in the longitudinal direction of the bar 18. This guide system 22 is guided in a corresponding opening in the recess 8.

Chaque boítier 3 est à base d'un plastique perméable à la lumière, en particulier teinté en couleur, et semi-dur, les faces et les insertions 24 étant conçues de façon étanche à la lumière. Dans les insertions 24, il est prévu respectivement une ouverture 36 pour le passage d'un système conducteur 37 du récepteur électrique 4.Each box 3 is based on a plastic permeable to light, in particular tinted color, and semi-hard, faces and inserts 24 being designed in a light-tight manner. In the inserts 24, there is provided respectively a opening 36 for the passage of a conductive system 37 of the electrical receiver 4.

L'appareil de signalisation 1 représenté sur la figure 1 présente également un couvercle de fermeture qui n'est pas représenté de façon plus détaillée, est posé sur le dernier boítier 3, c'est-à-dire le boítier supérieur, sous la couche intermédiaire d'un autre joint 16 et est relié au boítier 3. A cet effet, on peut utiliser également un élément d'accouplement 27. Cependant, on peut également imaginer que le couvercle de fermeture, qui ne présente pas de systèmes conducteurs électriques, est vissé sur le dernier boítier 3. Le récepteur électrique 4 comprend le système conducteur 37, qui est conçu comme une carte imprimée 39. La carte imprimée 39 est conçue avec une forme sensiblement en U et a deux branches 40 et 41. Entre les deux branches 40 et 41 est disposé un support 42 pour une lampe 43. A la place, on peut prévoir dans cette zone également un transmetteur de signal acoustique. Le support 42 est relié de façon électrique à la carte imprimée 39. De plus, une fiche 44 avec un grand nombre de broches 45 est disposée sur la branche 40 de la carte imprimée 39. Sur ces branches 45, au moins deux broches 45 sont reliées électriquement au support 42, les récepteurs électriques 4 disposés de façon linéaire et superposée dans les boítiers 3 étant commandés par le grand nombre des broches 45.The signaling device 1 shown in the Figure 1 also shows a closure cover which is not shown in more detail, is placed on the last box 3, that is to say the box upper, under the middle layer of another seal 16 and is connected to the housing 3. For this purpose, can also use a coupling element 27. However, one can also imagine that the cover closing, which has no systems electrical conductors, is screwed on the last box 3. The electric receiver 4 includes the conductive system 37, which is designed as a card printed 39. The printed card 39 is designed with a substantially U-shaped and has two branches 40 and 41. Between the two branches 40 and 41 is disposed a support 42 for a lamp 43. Instead, we can provide in this area also a signal transmitter acoustic. The support 42 is electrically connected on printed board 39. In addition, sheet 44 with a large number of pins 45 is arranged on the branch 40 of the printed map 39. On these branches 45, at at least two pins 45 are electrically connected to the support 42, the electrical receivers 4 arranged linearly and superimposed in the boxes 3 being controlled by the large number of pins 45.

La carte imprimée 39 présente également sur son extrémité, opposée à la fiche 44, de la branche 40 un logement de fiche 46, qui présente un nombre d'orifices de logement 52 correspondant au nombre des broches 45. Ce logement de fiche 46 est disposé dans la zone de l'ouverture 36 dans l'insertion 24 avec l'appareil de signalisation 1 monté, de sorte que le récepteur électrique 4 voisin peut être enfiché avec sa fiche 44 dans le logement 46 du récepteur électrique 4 situé au-dessous et qu'on peut ainsi avoir une liaison électrique continue entre la source d'énergie et le récepteur électrique 4 supérieur dans le boítier supérieur 3. La carte imprimée 39 peut être équipée à cet effet de composants électriques ou électroniques pour commander certaines fonctions du récepteur électrique 4 et/ou de l'influencer. Par exemple, on peut prévoir ici des éléments de temporisation.Printed card 39 also shows on its end, opposite plug 44, of branch 40 a plug housing 46, which has a number of holes housing 52 corresponding to the number of pins 45. This plug housing 46 is arranged in the area of the opening 36 in the insertion 24 with the apparatus of signaling 1 mounted, so that the receiver neighbor 4 electric can be plugged in with plug 44 in the housing 46 of the electrical receiver 4 located below and that we can thus have an affair between the power source and the upper 4 electric receiver in the housing upper 3. Printed card 39 can be equipped with this effect of electrical or electronic components to control certain receiver functions electric 4 and / or influence it. For example, we can provide timing elements here.

Grâce à la conception de l'appareil de signalisation 1 décrit ci-dessus, on a la possibilité de relier entre eux des boítiers voisins 3 ou de les séparer, sans qu'on ne soit obligé de tourner les boítiers voisins 3 les uns par rapport aux autres. De cette façon, les cartes imprimées 39 ou fiches 44 et le logement de fiche 46 de transmetteurs de signal voisins 2 sont protégés des détériorations ou d'une destruction consécutive à un mouvement de rotation.Thanks to the design of the device signaling 1 described above, we have the possibility to connect neighboring boxes 3 to one another or to separate, without having to turn the neighboring housings 3 relative to each other. Of this way, the printed cards 39 or cards 44 and the plug housing 46 of neighboring signal transmitters 2 are protected from damage or destruction following a rotational movement.

Sur les figures 7 à 15, on représente différentes positions des composants décrits plus haut les uns par rapport aux autres. Les figures 7 à 9 présentent ici une partie du boítier 3 avec l'élément d'accouplement 27 dans une vue latérale agrandie et une vue latérale en perspective, alors que les figures 10 à 14 présentent une vue de dessus tronquée du boítier 3 avec l'élément d'accouplement 27 dans le plan de l'élément de verrouillage 9.In Figures 7 to 15, different positions of the components described above by compared to others. Figures 7 to 9 show here part of the housing 3 with the coupling element 27 in an enlarged side view and a side view in perspective, while Figures 10 to 14 have a truncated top view of the housing 3 with the coupling element 27 in the plane of the element lock 9.

Sur la figure 7, on peut voir la position verrouillée entre le boítier 3 et l'élément d'accouplement 27. Dans le cas présent, l'élément de verrouillage 9 se trouve dans sa position supérieure à l'intérieur de l'évidement 8 du boítier 3. Dans cette position, la lame 20 s'engage dans l'ouverture d'arrêt 33, de sorte qu'une rotation relative de l'élément d'accouplement 27 par rapport au boítier 3 est bloquée par l'élément de verrouillage 9. A cet effet, l'ouverture d'arrêt 33 présent un bord d'arrêt 23. On peut voir sur la figure 7 également un autre dispositif d'affichage 10, qui est disposé sur l'enveloppe extérieure de l'élément d'accouplement 27.In figure 7, we can see the position locked between box 3 and element of coupling 27. In this case, the element of lock 9 is in its position above inside the recess 8 of the housing 3. In this position, the blade 20 engages in the stop opening 33, so that a relative rotation of the element coupling 27 relative to the housing 3 is blocked by the locking element 9. For this purpose, the stop opening 33 has a stop edge 23. We can see in Figure 7 also another device display 10, which is arranged on the envelope outside of the coupling element 27.

Sur la figure 8, on montre la façon dont la lame 20 peut être désengagée avec l'ouverture d'arrêt 33. A cet effet, la lame 20 est appuyée dans le sens contraire à son effet de ressort en direction de l'enveloppe extérieure 6 et déplacée en même temps dans le sens axial du boítier 3 en direction de la flèche 85. A cet effet, il est prévu sur la lame 20 la saillie d'arrêt 21, sur laquelle on peut poser par exemple un tournevis, afin d'appliquer la force nécessaire pour le déplacement de l'élément de verrouillage 9 à l'intérieur de l'évidement 8.In Figure 8, we show how the blade 20 can be disengaged with the stop opening 33. At this effect, the blade 20 is pressed in the opposite direction to its spring effect towards the envelope outside 6 and moved in the same direction axial of the housing 3 in the direction of arrow 85. At this effect, the stop projection is provided on the blade 20 21, on which one can for example place a screwdriver, in order to apply the force necessary for the movement of the locking element 9 to inside the recess 8.

Dans cette position, l'élément d'accouplement 27 peut être tourné par rapport au boítier 3, ce qui fait que la lame 20 avec l'élément de verrouillage 9 parvient derrière la paroi interne de l'élément d'accouplement 27 dans la zone de l'évidement 31.In this position, the coupling element 27 can be rotated relative to the housing 3, which makes that the blade 20 with the locking element 9 reaches behind the internal wall of the element 27 in the region of the recess 31.

Lors du mouvement de fermeture opposé à cette action, l'élément de verrouillage 9 est soulevé par une surface inclinée 86 disposée dans le sens périphérique de l'élément d'accouplement 27 dans sa position supérieure, représentée sur la figure 7, à l'intérieur de l'évidement 8. Afin d'obtenir un verrouillage sûr de la lame 20 dans l'ouverture d'arrêt 33, l'élément d'accouplement 27 présente également une surface inclinée 87 allant dans le sens radial de l'élément d'accouplement 27, qui déplace la lame 20 dans la direction radiale vers l'élément de verrouillage 9 lors d'un déplacement de l'élément d'accouplement 27 par rapport au boítier 3, de sorte que la lame 20 s'enclenche sous l'effet de sa force de ressort dans l'ouverture d'arrêt 33 lorsqu'elle atteint et dépasse le bord d'arrêt 23.During the closing movement opposite this action, the locking element 9 is lifted by a inclined surface 86 disposed in the peripheral direction of the coupling element 27 in its position upper, shown in Figure 7, inside of the recess 8. In order to obtain a secure locking of the blade 20 in the stop opening 33, the element coupling 27 also has a surface inclined 87 going in the radial direction of the element coupling 27, which moves the blade 20 in the radial direction towards the locking element 9 when displacement of the coupling element 27 by relative to the housing 3, so that the blade 20 snaps under the effect of its spring force in the stop opening 33 when it reaches and exceeds the stop edge 23.

La figure 10 représente la position verrouillée entre l'élément d'accouplement 27 et le boítier 3. On peut voir qu'on dispose globalement d'une course de déplacement entre la position verrouillée et la position ouverte de 26°. Cette course de déplacement est déterminée essentiellement par la longueur de l'évidement 31. En conséquence, l'évidement 12 est conçu également avec une longueur appropriée.Figure 10 shows the locked position between the coupling element 27 and the housing 3. On can see that we have a race of movement between the locked position and the 26 ° open position. This displacement race is essentially determined by the length of the recess 31. Consequently, the recess 12 is also designed with an appropriate length.

Sur la figure 11, on représente par la flèche 88 l'extraction par pression de la lame 20 de l'ouverture d'arrêt 33. Comme on l'a déjà décrit précédemment, la lame 20 est déplacée en même temps que l'élément de verrouillage 9 dans la direction axiale du boítier 3 à l'intérieur de l'évidement 8, de sorte que la lame 20 parvient dans une position bloquée derrière l'enveloppe intérieure 29 de l'élément d'accouplement 27.In FIG. 11, the arrow 88 represents pressure extraction of the blade 20 from the opening 33. As already described above, the blade 20 is moved at the same time as the element of locking 9 in the axial direction of the housing 3 to inside the recess 8, so that the blade 20 arrives in a locked position behind the envelope inside 29 of the coupling element 27.

Ensuite, l'élément d'accouplement 27 peut être tourné par rapport au boítier 3 en direction des flèches 89 pour obtenir la position d'ouverture à partir de la position de fermeture. On peut voir sur la figure 12 que la lame 20 se trouve derrière le bord d'arrêt 23 avec un mouvement de rotation de 3°.Then, the coupling element 27 can be turned relative to the housing 3 in the direction of arrows 89 to obtain the open position at from the closed position. We can see on the Figure 12 that the blade 20 is behind the edge stop 23 with a rotational movement of 3 °.

Si l'élément d'accouplement 27 est alors tourné des 23° restants par rapport au boítier 3, la came 14 s'engage derrière la saillie 13, de sorte que l'élément d'accouplement 27 est protégé également dans la position d'ouverture présentée sur la figure 13 contre une rotation réciproque involontaire des deux composants. Dans cette position, on peut alors séparer des transmetteurs de signaux voisins 2 ; pour cette opération, on peut sortir en tirant les cames 5 des guides à baïonnette 35 correspondantes de l'élément d'accouplement 27. Grâce à la conception de l'élément d'accouplement 27 et du boítier 3, on empêche à cette occasion un déplacement relatif de transmetteurs de signal voisin 2, c'est-à-dire du boítier 3 avec les systèmes conducteurs 37 disposés à l'intérieur.If the coupling element 27 is then turned 23 ° remaining relative to the housing 3, the cam 14 engages behind the projection 13, so that the element coupling 27 is also protected in the open position shown in Figure 13 against an involuntary reciprocal rotation of the two components. In this position, we can then separate neighboring signal transmitters 2; for this operation, you can exit by pulling the cams 5 corresponding bayonet guides 35 of the element 27. Thanks to the design of the element coupling 27 and the housing 3, this is prevented occasion a relative displacement of transmitters from neighboring signal 2, that is to say from the housing 3 with the conductive systems 37 arranged inside.

Sur les figures 14 et 15, on présente enfin encore le déplacement relatif de l'élément d'accouplement 27 par rapport au boítier 3, qui est nécessaire pour ramener l'élément d'accouplement 27 à la position de fermeture. Le mouvement de rotation est représenté ici par des flèches 90, et sur la figure 14 on indique la première surface inclinée 86 qui déplace, c'est-à-dire soulève l'élément de verrouillage 9 dans le sens axial du boítier 3. On peut voir que la surface inclinée 86 comprend à peu près une zone de 17° de l'évidement 31, avant que l'élément de verrouillage 9 soit soulevé à un niveau où sa lame 20 se trouve à la hauteur de l'ouverture d'arrêt 33. Sur la figure 15, on peut voir enfin que, après un mouvement de rotation d'environ 23°, la lame 20 est déplacée au-dessus de la deuxième surface inclinée 87 en direction du centre du boítier 3 et est donc prétendue, avant que la lame 20 s'engage ensuite dans l'ouverture d'arrêt 33.Finally, in FIGS. 14 and 15, the relative displacement of the coupling element 27 compared to the housing 3, which is necessary for return the coupling element 27 to the position of closing. The rotational movement is shown here by arrows 90, and in FIG. 14 the first inclined surface 86 which moves, that is to say raises the locking element 9 in the axial direction of the housing 3. We can see that the inclined surface 86 roughly includes a 17 ° zone of the recess 31, before the locking element 9 is lifted to a level where its blade 20 is at the height of the stop opening 33. In FIG. 15, we can see finally that after a rotational movement of about 23 °, the blade 20 is moved above the second inclined surface 87 towards the center of the housing 3 and is therefore claimed, before the blade 20 engages then in the stop opening 33.

Sur les figures 16 à 22, on présente un mode de réalisation différent de l'appareil de signalisation décrit plus haut dans ses détails concernant la liaison entre le boítier 3 et l'élément d'accouplement 27. Les composants identiques sont donc désignés par des chiffres de référence identiques.In FIGS. 16 to 22, a mode of different design of the signaling device described above in its details regarding the binding between the housing 3 and the coupling element 27. The identical components are therefore designated by identical reference figures.

La figure 17 présente un boítier 3, qui est sensiblement identique au boítier selon la figure 4. Dans la zone périphérique inférieure, c'est-à-dire la zone périphérique opposée à la came 5, le boítier 3 présente une came 100, qui dépasse de l'enveloppe extérieure 6 du boítier 3.Figure 17 shows a housing 3, which is substantially identical to the housing according to FIG. 4. In the lower peripheral area, i.e. the peripheral zone opposite the cam 5, the housing 3 has a cam 100, which protrudes from the envelope outside 6 of the housing 3.

L'élément d'accouplement 27 selon les figures 16 et 18 à 22 se différencie de l'élément d'accouplement 27 décrit plus haut par le fait qu'un élément élastique sous la forme d'une plaque 91 est inséré dans l'évidement 31. La plaque 91 est réalisée sous la forme d'une bande et avec une forme pratiquement de W, la plaque 91 présentant deux branches 92 et 93, qui sont coudées sur leurs extrémités libres dans le sens périphérique de l'élément d'accouplement 27 et s'appuient sur la surface interne de l'évidement 31. Entre les broches 92 et 93 s'étendent deux autres branches 94 et 95, sensiblement de même longueur, qui se touchent en formant un angle obtus et détermine pour l'essentiel les propriétés élastiques de la plaque. Dans le cas présent, on peut voir que la ligne de liaison des deux branches 94 et 95 est disposée à peu près au centre de l'évidement 31, ce qui est prévu en ce qui concerne l'étirement longitudinal ainsi qu'un étirement perpendiculaire à l'étirement longitudinal de l'évidement 31.The coupling element 27 according to FIGS. 16 and 18 to 22 differs from coupling element 27 described above by the fact that an elastic element in the form of a plate 91 is inserted into the recess 31. The plate 91 is produced in the form of a band and with a practically W shape, the plate 91 having two branches 92 and 93, which are angled on their free ends in the direction device of the coupling element 27 and are supported on the internal surface of the recess 31. Between pins 92 and 93 extend two others branches 94 and 95, substantially the same length, which touch each other at an obtuse angle and determine for essentially the elastic properties of the plate. In this case, we can see that the line of connection of the two branches 94 and 95 is arranged slightly near the center of the recess 31, which is provided in regarding the longitudinal stretch as well as a stretch perpendicular to the longitudinal stretch of the recess 31.

La plaque détermine des deux côtés des branches 92 et 93 une position d'arrêt 96 et 97, la position d'arrêt 96 étant disposée dans la zone de l'ouverture 32, de sorte que la came 100 peut être introduite par l'ouverture 32 dans la position d'arrêt 96 dans le sens axial de l'élément d'accouplement 27 et peut être guidée ensuite dans la position d'arrêt 97 au-delà de la plaque en faisant tourner l'élément d'accouplement 27 par rapport au boítier 3. Les deux positions finales de la came sont représentées sur les figures 21 et 22, la figure 21 comprenant la position non enclenchée entre l'élément d'accouplement 27 et le boítier 3 et la figure 22 la position enclenchée entre le boítier 3 et l'élément d'accouplement 27. Si la came est transférée de la position d'arrêt 96 à la position d'arrêt 97, l'élasticité de la plaque 91 est suffisante pour éviter le déplacement de la came 100.The plate determines on both sides of the branches 92 and 93 a stop position 96 and 97, the position stopper 96 being arranged in the opening area 32, so that the cam 100 can be introduced by the opening 32 in the stop position 96 in the direction axial of the coupling element 27 and can be then guided into the stop position 97 beyond the plate by rotating the coupling element 27 relative to the housing 3. The two end positions of the cam are shown in FIGS. 21 and 22, figure 21 including the position not engaged between the coupling element 27 and the housing 3 and the Figure 22 the position engaged between the housing 3 and the coupling element 27. If the cam is transferred from the stop position 96 to the stop position 97, the elasticity of the plate 91 is sufficient to avoid displacement of the cam 100.
