Description

Dispositif déclencheur d'alarme, notamment pour installation de détection d'incendieAlarm triggering device, in particular for a fire detection installation
L'invention concerne un dispositif déclencheur d'alarme destiné à une installation de détection d'incendie ou analogue.The invention relates to an alarm triggering device for a fire detection installation or the like.
On connaît déjà des dispositifs déclencheurs de ce genre qui sont réalisés le plus souvent sous la forme d'un boîtier propre à être placé par exemple près d'une issue de secours et à être actionnés manuellement pour déclencher un signal d'alarme sonore et/ou visuel.Triggering devices of this type are already known which are most often produced in the form of a box suitable for being placed, for example, near an emergency exit and to be actuated manually to trigger an audible alarm signal and / or visual.
De tels dispositifs doivent être d'un fonctionnement sûr pour permettre le déclenchement de l'alarme, laquelle doit rester enclenchée jusqu'à ce que l'on vienne réenclencher ou réarmer le dispositif sur intervention d'un agent de sécurité.Such devices must be of safe operation to allow the triggering of the alarm, which must remain triggered until the device is reset or reset on intervention of a security officer.
Ce réarmement ne doit pas être fait à distance mais sur place uniquement, l'agent de sécurité n'effectuant le réarmement que dans le cas où la situation anormale qui a généré l'incendie a été réparée.This rearming must not be done remotely but only on site, the safety officer carrying out the rearming only in the event that the abnormal situation which caused the fire has been repaired.
Les dispositifs déclencheurs du genre précité existent sous deux formes de réalisation principales, la première compre¬ nant un boîtier dit "bris de glace" et la seconde un boîtier à membrane déformable.Triggering devices of the aforementioned kind exist in two main embodiments, the first comprising a so-called "broken glass" box and the second a box with a deformable membrane.
Dans le premier cas, il faut briser une glace pour déclen¬ cher le signal d'alarme, ce qui oblige à changer de glace pour remettre en route ou réarmer ultérieurement le disposi- tif, lorsque la situation est redevenue normale.In the first case, a window must be broken to trigger the alarm signal, which requires changing the window to restart or rearm the device later, when the situation has returned to normal.
Dans le second cas, il s'agit d'une membrane en matière plastique qu'il convient de déformer pour l'amener en position d'alarme. Il faut ensuite changer la membrane ou faire venir un agent de sécurité pour la remettre dans sa position initiale non déformée.In the second case, it is a plastic membrane which must be deformed to bring it to the alarm position. Then you have to change the membrane or bring in a security guard to return it to its original, undeformed position.
Tous ces dispositifs connus ont en outre pour inconvénient de nécessiter un moyen d'éclairage, par exemple une lampe électrique, pour indiquer que le dispositif a été déclenché.All of these known devices have the further disadvantage of requiring a lighting means, for example an electric lamp, to indicate that the device has been triggered.
L'invention a notamment pour but de surmonter les inconvé¬ nients précités.The invention particularly aims to overcome the aforementioned drawbacks.
C'est en particulier un but de l'invention de procurer un dispositif déclencheur d'alarme du genre précité qui permet un déclenchement aisé d'une alarme sonore et/ou visuelle qui convient tout particulièrement aux installations de détec- tion d'incendie.It is in particular an object of the invention to provide an alarm triggering device of the aforementioned kind which allows easy triggering of an audible and / or visual alarm which is particularly suitable for fire detection installations.
C'est encore un but de l'invention de procurer un dispositif déclencheur de ce type qui soit d'une construction simple et robuste et qui ne nécessite pas de moyens d'éclairage.It is another object of the invention to provide a trigger device of this type which is of a simple and robust construction and which does not require lighting means.
C'est encore un but de l'invention de procurer un dispositif déclencheur de ce type qui fonctionne essentiellement par action mécanique.It is another object of the invention to provide a trigger device of this type which operates essentially by mechanical action.
L'invention propose à cet effet un dispositif déclencheur pour alarme ou analogue, ce dispositif comprenant :To this end, the invention provides a trigger device for an alarm or the like, this device comprising:
- un boîtier comportant une fenêtre de visualisation;- a housing comprising a viewing window;
- une plaque d'appui montée dans le boîtier et susceptible d'être poussée, à partir d'une position normale de repos, vers une position de déclenchement;- a support plate mounted in the housing and capable of being pushed, from a normal rest position, to a release position;
- une plaque indicatrice portant un repère indicateur et montée mobile en translation sur la plaque d'appui en étant sollicitée élastiquement, à partir d'une position de ver¬ rouillage, vers une position de déverrouillage en laquelle le repère indicateur est en regard de la fenêtre de visuali¬ sation; et - des moyens de verrouillage interposés entre le boîtier et la plaque indicatrice et propres à maintenir la plaque indicatrice en position de verrouillage lorsque la plaque d'appui est dans sa position de repos et à libérer la plaque indicatrice vers sa position de déverrouillage lorsque la plaque d'appui est poussée vers sa position de déclenche¬ ment.- an indicator plate carrying an indicator mark and mounted movable in translation on the support plate while being resiliently biased, from a locking position, towards an unlocking position in which the indicator mark is opposite the viewing window; and - locking means interposed between the housing and the indicator plate and suitable for holding the indicator plate in the locking position when the support plate is in its rest position and for releasing the indicator plate towards its unlocking position when the plate support is pushed to its trigger position.
Ainsi, lorsqu'une poussée est exercée sur la plaque d'appui, celle-ci se déplace vers sa position de déclenchement, ce qui libère les moyens de verrouillage et permet à la plaque indicatrice d'être sollicitée élastiquement vers sa position de déverrouillage dans laquelle le repère indicateur est en regard de la fenêtre de visualisation.Thus, when a thrust is exerted on the support plate, the latter moves towards its release position, which frees the locking means and allows the indicator plate to be resiliently biased towards its unlocking position in which the indicator mark is opposite the viewing window.
Il n'est alors pas nécessaire de prévoir un moyen d'éclai¬ rage ou analogue pour visualiser le déclenchement du dispositif.It is then not necessary to provide a means of lighting or the like to display the triggering of the device.
Pour réenclencher ou réarmer le dispositif, il suffit de faire venir un agent de sécurité pour qu'il déplace la plaque indicatrice de la position de déverrouillage à la position de verrouillage, et cela sans qu'il soit nécessaire de changer une pièce du dispositif.To reset or reset the device, simply bring in a security agent to move the indicator plate from the unlocking position to the locking position, without having to change a part of the device.
Dans une forme de réalisation préférée de l'invention, le boîtier comprend en outre une fenêtre d'appui permettant à un utilisateur d'exercer une poussée sur la plaque d'appui au travers de cette fenêtre d'appui.In a preferred embodiment of the invention, the housing further comprises a support window allowing a user to exert a push on the support plate through this support window.
De façon avantageuse, la fenêtre de visualisation et la fenêtre d'appui sont ménagées au travers d'un couvercle monté sur un fond de boîtier.Advantageously, the viewing window and the support window are formed through a cover mounted on a case bottom.
De façon préférentielle, la plaque d'appui est montée à pivotement autour d'un axe prévu à une première extrémité de la plaque d'appui et elle est sollicitée vers sa position de repos par au moins un ressort de rappel interposé entre le boîtier et une seconde extrémité de la plaque d'appui, située à l'opposé de la première extrémité.Preferably, the support plate is pivotally mounted about an axis provided at a first end of the support plate and it is urged towards its rest position by at least one return spring interposed between the housing and a second end of the support plate, located opposite the first end.
Selon une autre caractéristique de l'invention,- la plaque d'appui est au moins en partie transparente, ce qui permet au repère indicateur de la plaque indicatrice d'être visible au travers de la plaque d'appui.According to another characteristic of the invention, - the support plate is at least partially transparent, which allows the indicator mark of the indicator plate to be visible through the support plate.
Selon une autre caractéristique, la plaque indicatrice est sollicitée vers la position de déverrouillage par au moins un ressort de rappel interposé entre la plaque indicatrice et le boîtier ou entre la plaque indicatrice et la plaque d'appui.According to another characteristic, the indicator plate is biased towards the unlocking position by at least one return spring interposed between the indicator plate and the housing or between the indicator plate and the support plate.
Dans une forme de réalisation de l'invention, la plaque indicatrice comporte une découpe de forme homologue de celle de la fenêtre de visualisation et venant en regard de celle- ci dans la position de verrouillage de la plaque indicatrice et une zone adjacente' à cette découpe, portant le repère indicateur et venant en regard de la fenêtre de visualisa¬ tion dans la position de déverrouillage de la plaque indicatrice.In one embodiment of the invention, the indicator plate has a cutout homologous to that of the viewing window and coming opposite it in the locking position of the indicator plate and an area adjacent to this cutout, bearing the indicator and coming opposite the viewing window in the unlocked position of the indicator plate.
Ainsi, le repère indicateur n'apparaît derrière la fenêtre de visualisation que dans la position de déverrouillage de la plaque indicatrice.Thus, the indicator mark appears behind the display window only in the unlocking position of the indicator plate.
De façon avantageuse, la plaque indicatrice est colorée, ce qui fournit ainsi un repère indicateur coloré.Advantageously, the indicator plate is colored, which thus provides a colored indicator mark.
Selon une autre caractéristique de l'invention, les moyens de verrouillage comprennent au moins un ergot s'étendant à partir du boîtier et propre à s'engager derrière un épaule- ent de retenue de la plaque indicatrice lorsque la plaque d'appui est en position de repos et que la plaque indica¬ trice est en position de verrouillage, ledit ergot étant propre à se dégager de l'épaulement de retenue lorsque la plaque d'appui est poussée vers sa position de déclenche¬ ment, ledit ergot possédant en outre un côté incliné en forme de rampe propre à permettre le réarmement du disposi¬ tif en déplaçant la plaque indicatrice de la position de déverrouillage à la position de verrouillage.According to another characteristic of the invention, the locking means comprise at least one lug extending from the housing and suitable for engaging behind a shoulder for retaining the indicator plate when the support plate is in rest position and the indicator plate is in the locked position, said lug being able to disengage from the retaining shoulder when the support plate is pushed towards its release position, said lug further having one side tilted in form of ramp suitable for resetting the device by moving the indicator plate from the unlocking position to the locking position.
L'invention prévoit en outre une clé susceptible d'être introduite par un passage du boîtier pour déplacer la plaque indicatrice de la position de déverrouillage à la position de verrouillage en vue d'engager l'ergot derrière l'épaule- ment de retenue.The invention further provides a key capable of being introduced by passing the housing to move the indicator plate from the unlocking position to the locking position in order to engage the lug behind the retaining shoulder.
Ainsi, le réarmement du dispositif ne peut se faire qu'à l'aide d'une clé tenue à la disposition d'un agent de sécurité.Thus, resetting the device can only be done using a key made available to a security officer.
Suivant une autre caractéristique de l'invention, le dispositif comprend en outre un microrupteur prévu dans le boîtier et sollicité en appui par une saillie dépendant de la plaque indicatrice lorsque cette dernière est en position de verrouillage.According to another characteristic of the invention, the device further comprises a microswitch provided in the housing and urged to bear by a projection depending on the indicator plate when the latter is in the locked position.
Ainsi, lorsque le dispositif est déclenché, la plaque indicatrice est sollicité vers sa position de déverrouilla¬ ge, si bien que le microrupteur n'est plus actionné par la saillie, ce qui déclenche une alarme.Thus, when the device is triggered, the indicator plate is biased towards its unlocked position, so that the microswitch is no longer actuated by the projection, which triggers an alarm.
Dans la description qui suit, faite à titre d'exemple, on se réfère aux dessins annexés, sur lesquels :In the description which follows, given by way of example, reference is made to the appended drawings, in which:

Le fond de boîtier 12 comprend une base carrée 13 rattachée à une paroi périphérique 16 définissant une face ouverte carrée sur laquelle est monté le couvercle 14.As shown in Figures 1 and 2, the trigger device comprises a housing 10 formed of a housing bottom 12 and a cover 14. The housing bottom 12 comprises a square base 13 attached to a peripheral wall 16 defining an open face square on which the cover 14 is mounted.
Entre le fond de boîtier 12 et le couvercle 14 est disposée une platine 18 comportant une base 20 s'étendant parallèle¬ ment à la base 13 du fond de boîtier.Between the bottom of the housing 12 and the cover 14 is disposed a plate 18 having a base 20 extending parallel to the base 13 of the bottom of the housing.
Dans le couvercle 14 du boîtier sont ménagées une fenêtre de visualisation 22 et une fenêtre d'appui 24 qui ont sensible- ment la même largeur, mais des hauteurs différentes (figures 1 à 3). La fenêtre de visualisation 22, située vers le bas des figures 1 à 3, possède en effet une hauteur inférieure à celle de la fenêtre d'appui 24, située vers le haut des mêmes figures.In the cover 14 of the housing are provided a viewing window 22 and a support window 24 which have substantially the same width, but different heights (Figures 1 to 3). The viewing window 22, located towards the bottom of FIGS. 1 to 3, in fact has a height less than that of the support window 24, located towards the top of the same figures.
Le dispositif comprend en outre une plaque d'appui 26 montée dans le boîtier 10, immédiatement derrière le couvercle 14. Dans l'exemple de réalisation, la plaque d'appui 26 est réalisée dans une matière transparente, par exemple en verre minéral ou en verre organique, et elle s*étend sur pratique¬ ment toute la hauteur du boîtier en recouvrant ainsi les fenêtres 22 et 24.The device further comprises a support plate 26 mounted in the housing 10, immediately behind the cover 14. In the embodiment, the support plate 26 is made of a transparent material, for example mineral glass or organic glass, and it extends over the entire height of the housing, thus covering the windows 22 and 24.
La plaque d'appui 26 (figure 6) a une forme générale rectan- gulaire et elle comprend une première extrémité 28 (extré¬ mité inférieure) montée à pivotement autour d'un axe XX s'étendant parallèlement à la base 13 du fond de boîtier 12 (figures 1, 2, 6 et 7).The support plate 26 (FIG. 6) has a generally rectangular shape and it comprises a first end 28 (lower end) pivotally mounted around an axis XX extending parallel to the base 13 of the bottom of housing 12 (Figures 1, 2, 6 and 7).
Pour cela, la première extrémité 28 de la plaque d'appui 26 comporte un pivot 30 délimité à côté d'une fenêtre 31 (figure 6) et s'engageant dans deux logements 32 du couver¬ cle, lesquels sont fermés chacun par un prolongement 34 du fond de boîtier 12 (figures 2 et 7) lorsque le couvercle est monté sur le fond de boîtier.For this, the first end 28 of the support plate 26 has a pivot 30 delimited next to a window 31 (Figure 6) and engaging in two housings 32 of the key cover, which are each closed by an extension 34 of the housing bottom 12 (Figures 2 and 7) when the cover is mounted on the housing bottom.
La plaque d'appui 26 comprend en outre une seconde extrémité 36, opposée à la première extrémité 28 précitée, laquelle est sollicitée par deux ressorts de compression 38 (figures 1 et 2) interposés chacun entre la platine 18 du boîtier et la plaque d'appui 26.The support plate 26 further comprises a second end 36, opposite the first end 28 above, which is biased by two compression springs 38 (Figures 1 and 2) each interposed between the plate 18 of the housing and the plate support 26.
Les ressorts 38 sollicitent ainsi la plaque d'appui 26 vers une position de repos, telle que représentée sur les figures 1, 2 et 11, dans laquelle la plaque d'appui 26 vient s'appliquer intérieurement contre le couvercle 14.The springs 38 thus urge the support plate 26 towards a rest position, as shown in FIGS. 1, 2 and 11, in which the support plate 26 is applied internally against the cover 14.
La plaque d'appui 26 est susceptible d'être poussée, à partir de sa position normale de repos, vers une position d'actionnement ou de déclenchement lorsqu'une poussée P (figure 2) est appliquée sur la seconde extrémité 36 de la plaque d'appui 26, au travers de la fenêtre d'appui 24.The support plate 26 can be pushed from its normal rest position to a position actuation or tripping when a thrust P (FIG. 2) is applied to the second end 36 of the support plate 26, through the support window 24.
Lorsqu'une telle poussée est exercée, la plaque d'appui pivote autour de l'axe XX en assurant la compression des ressorts 38 et cette plaque d'appui revient vers sa position de repos lorsque la poussée n'est plus exercée.When such a thrust is exerted, the support plate pivots about the axis XX ensuring the compression of the springs 38 and this support plate returns to its rest position when the thrust is no longer exerted.
Le dispositif de l'invention comprend en outre une plaque indicatrice 40 représentée en trait interrompu sur la figure 1 et dont la forme générale apparaît sur les figures 9 et 10.The device of the invention further comprises an indicator plate 40 shown in broken lines in FIG. 1 and the general shape of which appears in FIGS. 9 and 10.
La plaque 40 est montée mobile en translation sur la plaque d'appui 26 suivant une direction de translation YY perpendi¬ culaire à la direction de l'axe XX.The plate 40 is mounted movable in translation on the support plate 26 in a direction of translation YY perpendicular to the direction of the axis XX.
La plaque indicatrice 40 possède une forme générale rectan- gulaire délimitée par un côté inférieur 42, un côté supé¬ rieur 44 et deux côtés latéraux 46 qui se raccordent perpendiculairement au côté inférieur 42. La plaque 40 comporte deux glissières 47 formées respectivement sur ses deux côtés latéraux 46 (figures 9 et 10) et propres à coopérer avec deux bords latéraux 49 de la plaque d'appui 26 (figure 6). La plaque indicatrice peut ainsi coulisser par rapport à la plaque d'appui en restant solidaire de cette dernière.The indicator plate 40 has a generally rectangular shape delimited by a lower side 42, a higher side 44 and two lateral sides 46 which are connected perpendicularly to the lower side 42. The plate 40 has two slides 47 formed respectively on its two lateral sides 46 (FIGS. 9 and 10) and suitable for cooperating with two lateral edges 49 of the support plate 26 (FIG. 6). The indicator plate can thus slide relative to the support plate while remaining integral with the latter.
La plaque indicatrice 40 comporte deux épaulements 48 se rattachant au côté supérieur 44 et faisant saillie respecti¬ vement par rapport aux deux côtés latéraux 46.The indicator plate 40 has two shoulders 48 which are attached to the upper side 44 and which project respectively from the two lateral sides 46.
Les épaulements 48 sont propres à coopérer chacun avec un ergot 50 (figures 1, 2, 3, 11 et 12) rattaché au couvercle 14 et s'étendant en direction de la base 13 du fond de boîtier. Chacun des ergots 50 comprend un côté supérieur 52 rattaché perpendiculairement au couvercle 14 et un côté incliné 54 formant rampe (figures 11 et 12). La plaque indicatrice 40 est sollicitée élastiquement en direction de la partie inférieure du boîtier (du côté de l'axe XX) par deux ressorts hélicoïdaux de traction 56 (figures 1 et 4). Chaque ressort 56 a une extrémité engagée dans- une encoche 58 de l'épaulement 48 (figure 9) et une autre extrémité engagée autour d'un pivot 60 dépendant du couvercle 14 et venant en appui contre un bossage 62 de la platine (figure 4).The shoulders 48 are adapted to each cooperate with a lug 50 (Figures 1, 2, 3, 11 and 12) attached to the cover 14 and extending in the direction of the base 13 of the bottom of the housing. Each of the lugs 50 includes an upper side 52 attached perpendicularly to the cover 14 and an inclined side 54 forming a ramp (Figures 11 and 12). The indicator plate 40 is resiliently biased towards the lower part of the housing (on the side of the axis XX) by two helical tension springs 56 (Figures 1 and 4). Each spring 56 has one end engaged in a notch 58 of the shoulder 48 (FIG. 9) and another end engaged around a pivot 60 depending on the cover 14 and coming to bear against a boss 62 of the plate (FIG. 4 ).
Les deux ergots 50 et les deux épaulements 48 constituent ainsi des moyens de verrouillage qui permettent de maintenir la plaque indicatrice 40 dans une position de verrouillage (figure 11) lorsque la plaque d'appui 26 est dans sa position normale de repos.The two lugs 50 and the two shoulders 48 thus constitute locking means which make it possible to maintain the indicator plate 40 in a locking position (FIG. 11) when the support plate 26 is in its normal rest position.
Lorsqu'une poussée P est exercée sur la plaque d'appui 26, la seconde extrémité 36 de celle-ci s'éloigne du couvercle, si bien que les épaulements 48 se dégagent des ergots correspondants 50, ce qui libère la plaque indicatrice 40. Cette dernière est alors sollicitée par les deux ressorts 56 pour se déplacer vers une position de déverrouillage, comme représenté sur la figure 12.When a thrust P is exerted on the support plate 26, the second end 36 of the latter moves away from the cover, so that the shoulders 48 are released from the corresponding lugs 50, which releases the indicator plate 40. The latter is then urged by the two springs 56 to move towards an unlocking position, as shown in FIG. 12.
Dans la variante de réalisation représentée à la figure 8, la plaque indicatrice 40 est sollicitée élastiquement en direction de la partie inférieure du boîtier par deux ressorts hélicoïdaux de compression 156 s'étendant parallè¬ lement à l'axe YY. Chaque ressort 156 a une extrémité s'engageant autour d'un ergot 157 de la plaque d'appui 26 et une autre extrémité s'engageant autour d'un ergot 158 du prolongement 48 de la plaque indicatrice 40.In the alternative embodiment shown in Figure 8, the indicator plate 40 is resiliently biased towards the lower part of the housing by two helical compression springs 156 extending parallel to the axis YY. Each spring 156 has one end engaging around a lug 157 of the support plate 26 and another end engaging around a lug 158 of the extension 48 of the indicator plate 40.
Comme on le voit sur la figure 9, la plaque indicatrice 40 comporte une découpe 64 de forme homologue de celle de la fenêtre de visualisation 22 et venant en regard de celle-ci dans la position de verrouillage de la plaque indicatrice (figures 1, 2 et 11). La plaque 40 comprend en outre une zone 66 adjacente à la découpe 64 et située entre cette dernière et le côté 44. La zone 66 porte un repère indica- teur 68 propre à venir en regard de la fenêtre de visualisa¬ tion 22 lorsque la plaque indicatrice est dans sa position de déverrouillage (figure 12).As can be seen in FIG. 9, the indicator plate 40 has a cutout 64 of shape homologous to that of the viewing window 22 and coming opposite it in the locking position of the indicator plate (FIGS. 1, 2 and 11). The plate 40 further comprises a zone 66 adjacent to the cutout 64 and situated between the latter and the side 44. The zone 66 carries a mark indicating teur 68 able to come opposite the viewing window 22 when the indicator plate is in its unlocked position (FIG. 12).
Le repère indicateur 68 peut être une inscription ou de préférence une zone colorée, par exemple de couleur rouge ou verte.The indicator mark 68 can be an inscription or preferably a colored zone, for example of red or green color.
Dans une forme de réalisation préférentielle, toute la plaque indicatrice 40 est moulée dans une matière plastique de couleur vive, par exemple rouge ou verte, si bien que cette couleur n'apparaît derrière la fenêtre de visualisa¬ tion 22 que lorsque la plaque indicatrice 40 est dans la position de déverrouillage représentée à la figure 12.In a preferred embodiment, the entire indicator plate 40 is molded from a brightly colored plastic material, for example red or green, so that this color appears behind the display window 22 only when the indicator plate 40 is in the unlocked position shown in Figure 12.
Comme montré à la figure 1, le dispositif de l'invention comprend en outre une clé 70 ayant une forme de U à deux branches 72 susceptibles d'être introduites respectivement dans deux passages 74 du couvercle du boîtier pour venir en appui contre le côté inférieur 42 de la plaque indicatrice 40 (figures 1 et 5). Par introduction de la clé 70, on peut ainsi déplacer la plaque indicatrice 40 de la position de déverrouillage (figure 12) jusqu'à la position de verrouil¬ lage (figure 11). Au cours de ce déplacement, le côté incliné 54 en forme de rampe des ergots 50 vient coopérer avec la plaque indicatrice 40 qui s'écarte ainsi légèrement du couvercle, jusqu'à ce que les ergots 50 viennent en butée derrière les épaulements 48.As shown in Figure 1, the device of the invention further comprises a key 70 having a U shape with two branches 72 which can be inserted respectively in two passages 74 of the housing cover to come into abutment against the lower side 42 of the indicator plate 40 (Figures 1 and 5). By introduction of the key 70, it is thus possible to move the indicator plate 40 from the unlocking position (FIG. 12) to the locking position (FIG. 11). During this movement, the inclined side 54 in the form of a ramp of the lugs 50 cooperates with the indicator plate 40 which thus deviates slightly from the cover, until the lugs 50 come into abutment behind the shoulders 48.
Comme on le voit plus particulièrement sur la figure 4, le dispositif comprend également un microrupteur 76 monté sur la base 20 de la platine du boîtier et propre à coopérer avec une saillie 78 (figures 9 à 12) dépendant de la plaque indicatrice 40. Le microrupteur 76 est sollicité en appui par la saillie 78 lorsque la plaque indicatrice 40 est en position de verrouillage. Il n'est plus sollicité par la plaque indicatrice, lorsque cette dernière est en position de déverrouillage. Le dispositif fonctionne de la façon suivante.As can be seen more particularly in FIG. 4, the device also comprises a microswitch 76 mounted on the base 20 of the plate of the housing and suitable for cooperating with a projection 78 (FIGS. 9 to 12) depending on the indicator plate 40. The microswitch 76 is biased by the projection 78 when the indicator plate 40 is in the locked position. It is no longer requested by the indicator plate when the latter is in the unlocked position. The device operates as follows.
Le boîtier 10 est destiné à être placé, par exemple près d'une issue de secours, pour être déclenché manuellement lorsqu'une situation de danger apparaît, par exemple en cas d'incendie.The housing 10 is intended to be placed, for example near an emergency exit, to be triggered manually when a danger situation appears, for example in the event of a fire.
Le dispositif se trouve normalement dans la position repré¬ sentée aux figures 1, 2 et 11, dans laquelle la plaque d'appui 26 est dans sa position normale de repos et la plaque indicatrice 40 en position de verrouillage. Dans cette position, le microrupteur 76 est sollicité en appui par la saillie 78. Le microrupteur 76 est raccordé à une alarme sonore et/ou visuelle.The device is normally in the position shown in Figures 1, 2 and 11, in which the support plate 26 is in its normal rest position and the indicator plate 40 in the locked position. In this position, the microswitch 76 is urged to bear by the projection 78. The microswitch 76 is connected to an audible and / or visual alarm.
En cas de danger, une poussée P est appliquée manuellement au travers de la fenêtre d'appui 22 sur la plaque d'appui 26, ce qui provoque le déplacement de la plaque indicatrice vers la position de déverrouillage représentée à la figu- re 12.In the event of danger, a thrust P is applied manually through the support window 22 on the support plate 26, which causes the displacement of the indicator plate towards the unlocking position shown in FIG. 12.
Il en résulte que le microrupteur n'est plus sollicité par la saillie, si bien que ce dernier déclenche automatiquement l'alarme.As a result, the microswitch is no longer requested by the projection, so that the latter automatically triggers the alarm.
Par ailleurs, le repère 68 apparaît au travers de la fenêtre de visualisation 22, signalant ainsi que l'alarme a été déclenchée.Furthermore, the reference 68 appears through the viewing window 22, thus signaling that the alarm has been triggered.
La plaque indicatrice 40 ne peut être ramenée vers sa position de verrouillage que par une personne autorisée, par exemple un agent de sécurité, disposant de la clé 70 appro¬ priée. The indicator plate 40 can only be brought back to its locking position by an authorized person, for example a security agent, having the appropriate key 70.
