Description

L'invention a trait à un dispositif de type déclencheur manuel, et plus particulièrement un tel dispositif comprenant un mécanisme de déclenchement et un boîtier logeant le mécanisme de déclenchement, le mécanisme de déclenchement comprenant une plaque-poussoir et une plaque-coulisse montées chacune à translation dans le boîtier, le mécanisme de déclenchement présentant un état armé, où la plaque-poussoir bloque la translation de la plaque-coulisse, et un état déclenché, où la plaque poussoir libère la translation de la plaque-coulisse.The invention relates to a device of the manual trigger type, and more particularly to such a device comprising a trigger mechanism and a housing housing the trigger mechanism, the trigger mechanism comprising a push plate and a slide plate each mounted to translation in the housing, the trigger mechanism having an armed state, where the push plate blocks the translation of the slide plate, and a tripped state, where the push plate releases the translation of the slide plate.

Les déclencheurs manuels sont largement utilisés, en particulier dans les lieux d'accueil du public, à des fins sécuritaires notamment. Il s'agit de permettre à un individu d'agir sur un système plus étendu, de complexité variée, simplement par appui sur la plaque-poussoir du déclencheur.Manual triggers are widely used, in particular in places of public reception, for security purposes in particular. It is a question of allowing an individual to act on a more extensive system, of varied complexity, simply by pressing on the push plate of the release.

On prévoit par exemple des déclencheurs manuels pour commander la fermeture de portes coupe-feu ou l'ouverture de portes de secours. On utilise des déclencheurs de ce type aussi pour le déclenchement d'alarmes incendie ou l'actionnement de systèmes de désenfumage. Ces déclencheurs sont aussi employés pour permettre de couper en urgence des circuits électriques ou de gaz, ou arrêter une machine ou une installation.For example, manual triggers are provided for controlling the closing of fire doors or the opening of emergency doors. Triggers of this type are also used for triggering fire alarms or activating smoke extraction systems. These triggers are also used to allow emergency shutdown of electrical or gas circuits, or to stop a machine or an installation.

FR 2 707 784 A1 au nom de la Demanderesse décrit un déclencheur manuel du type décrit en introduction. Ce déclencheur manuel permet de signaler qu'un déclenchement a été provoqué à l'aide d'une plaque indicatrice. FR 2 707 784 A1 in the name of the Applicant describes a manual release of the type described in the introduction. This manual trip unit is used to indicate that a trip has been triggered by means of an indicator plate.

Un déclencheur manuel doit être fiable. Du fait de leur utilisation très répandue et de leur caractère sécuritaire, les déclencheurs doivent être simples à entretenir.A manual call point must be reliable. Because of their widespread use and their safety, triggers should be easy to maintain.

En outre, plusieurs normes imposent aux déclencheurs manuels de prévoir une fonction de test de la partie électronique des déclencheurs. Cela concerne par exemple les déclencheurs manuels destinés aux systèmes de détection automatique d'incendie, qui doivent respecter la norme européenne EN54-11. Cela implique typiquement de pouvoir faire jouer les contacts de cette électronique sans ouvrir le boîtier lors d'un essai de routine.In addition, several standards require manual trip units to provide a test function for the electronic part of the trip units. This concerns, for example, manual call points intended for automatic fire detection systems, which must comply with European standard EN54-11. This typically involves be able to operate the contacts of this electronic without opening the case during a routine test.

Les déclencheurs manuels connus donnent globalement satisfaction.Known manual triggers are generally satisfactory.

Afin d'améliorer leur fiabilité et leur entretien, la Demanderesse a cependant cherché à en simplifier encore la conception.In order to improve their reliability and their maintenance, the Applicant has however sought to further simplify their design.

Selon un autre aspect, la Demanderesse s'est fixé comme objectif de pouvoir tester l'électronique sans action sur l'état du mécanisme de déclenchement. Cet objectif l'a contrainte à revoir sensiblement le mécanisme des déclencheurs connus.According to another aspect, the Applicant has set itself the objective of being able to test the electronics without affecting the state of the trigger mechanism. This objective forced her to substantially review the mechanism of known triggers.

Elle propose un dispositif de type déclencheur manuel comprenant un mécanisme de déclenchement et un boîtier logeant le mécanisme de déclenchement. Le mécanisme de déclenchement comprend une plaque-poussoir et une plaque-coulisse montées chacune à translation dans le boîtier. Le mécanisme de déclenchement présente un état armé, où la plaque-poussoir bloque la translation de la plaque-coulisse, et un état déclenché, où la plaque poussoir libère la translation de la plaque-coulisse.It proposes a device of the manual trip type comprising a trip mechanism and a box housing the trip mechanism. The trigger mechanism includes a push plate and a slide plate each translatably mounted in the housing. The trigger mechanism has an armed state, where the push plate blocks the translation of the slide plate, and a tripped state, where the push plate releases the translation of the slide plate.

La plaque-poussoir comprend une colonne centrale et la plaque-coulisse comprend un trou oblong dans lequel s'engage la colonne centrale. La colonne centrale et le trou oblong comprennent de premières sections, homologues l'une de l'autre, conformées de manière à venir mutuellement en prise dans l'état armé du mécanisme et de secondes sections, homologues l'une de l'autre et adjacentes aux premières sections, conformées de manière à coulisser l'une par rapport à l'autre dans l'état déclenché du mécanisme.The push plate includes a central column and the slide plate includes an oblong hole in which the central column engages. The central column and the oblong hole comprise first sections, homologous to each other, shaped so as to engage each other in the armed state of the mechanism and second sections, homologous to each other and adjacent to the first sections, shaped so as to slide relative to one another in the triggered state of the mechanism.

Le déclencheur proposé est plus fiable, du fait d'un mécanisme de déclenchement simplifié. L'engagement d'un genre nouveau entre la plaque-poussoir et la plaque-coulisse a pour effet de diminuer la pression à appliquer sur la plaque-poussoir afin de déclencher tout en limitant le risque de déclenchements involontaires. Le déclenchement se révèle en outre plus fiable.The proposed trigger is more reliable, due to a simplified trigger mechanism. The engagement of a new kind between the push plate and the slide plate has the effect of reducing the pressure to be applied on the push plate in order to trigger while limiting the risk of unintentional triggering. The triggering also proves to be more reliable.

Le déclencheur proposé peut fonctionner, pour ce qui concerne la plaque-poussoir, avec un unique organe de rappel élastique, qui prend appui sensiblement au centre de cette plaque. Ceci diminue le coût de ce déclencheur et augmente sa fiabilité. Cette disposition centrale libère en outre de l'espace à l'intérieur du boîtier, facilitant ainsi l'accès aux éléments de l'électronique.The proposed trigger can operate, as regards the push plate, with a single elastic return member, which bears substantially in the center of this plate. This decreases the cost of this trigger and increases its reliability. This central arrangement also frees up space inside the housing, thus facilitating access to the electronic components.

On fait référence aux figures 1 à 4.We refer to figures 1 to 4 .

Ces figures montrent un déclencheur manuel 1, tel qu'il s'installe classiquement sur une paroi verticale.These figures show a manual trip unit 1, as it is conventionally installed on a vertical wall.

Le déclencheur 1 comprend un boîtier 10 en forme générale de parallélépipède rectangle, avec une face avant 120 munie d'une fenêtre principale 122 et une face arrière 130, opposée à la face avant 120, par l'intermédiaire de laquelle le boîtier 10 se fixe sur la paroi. La face arrière 130 et la face avant 120 sont mutuellement opposées selon une première direction, ou direction X.The trigger 1 comprises a housing 10 in the general shape of a rectangular parallelepiped, with a front face 120 provided with a main window 122 and a rear face 130, opposite to the front face 120, through which the housing 10 is fixed. on the wall. The rear face 130 and the front face 120 are mutually opposed in a first direction, or X direction.

Le boîtier 10 présente en outre une première paire de faces latérales, mutuellement opposées selon une seconde direction, ou direction Y, orthogonale à la direction X : une face de gauche 140, à gauche de la figure 1, et une face de droite 150. Le boîtier 10 présente encore une seconde paire de faces latérales, mutuellement opposées selon une troisième direction, ou direction Z, orthogonale aux directions X et Y : une face supérieure 160, en haut de la figure 1, et une face inférieure 170.The housing 10 also has a first pair of side faces, mutually opposed in a second direction, or Y direction, orthogonal to the X direction: a left face 140, to the left of the figure 1 , and a right face 150. The housing 10 also has a second pair of side faces, mutually opposed in a third direction, or Z direction, orthogonal to the X and Y directions: an upper face 160, at the top of the figure 1 , and a lower face 170.

Typiquement, la direction Z correspond sensiblement à la verticale et la direction Y à l'horizontale.Typically, the Z direction corresponds substantially to the vertical and the Y direction to the horizontal.

Ici, la fenêtre 122 est généralement rectangulaire et s'étend sensiblement de manière horizontale.Here, the window 122 is generally rectangular and extends substantially horizontally.

La face avant 120 est en outre munie d'une fenêtre supplémentaire 124, optionnelle. Cette fenêtre supplémentaire 124 présente une allure généralement rectangulaire, de dimensions inférieures à la fenêtre principale 122. Cette fenêtre supplémentaire 124 laisse apparaître une plaque indicatrice (non représentée sur les figures), par exemple du type décrit dans FR 2 707 784 A1 . La plaque indicatrice signale visuellement l'état du déclencheur manuel 1.The front face 120 is also provided with an additional window 124, optional. This additional window 124 has a generally rectangular appearance, of smaller dimensions than the main window 122. This additional window 124 reveals an indicator plate (not shown in the figures), for example of the type described in FR 2 707 784 A1 . The indicator plate visually indicates the status of manual call point 1.

On fait référence à la figure 5.We refer to the figure 5 .

Le boîtier 10 est réalisé en plusieurs parties.The housing 10 is made in several parts.

Le boîtier 10 comprend une pièce élémentaire conformée en un capot 12. Le capot 12 est généralement creux avec une face avant correspondant à la face avant 120 du boîtier 10 et une face arrière ouverte sur l'intérieur du capot 12. Ici, le capot 12 est conformé en une coque.The housing 10 comprises an elementary part shaped as a cover 12. The cover 12 is generally hollow with a front face corresponding to the front face 120 of the housing 10 and a rear face open to the inside of the cover 12. Here, the cover 12 is shaped into a shell.

Le boîtier 10 comprend en outre une seconde pièce élémentaire conformée en une platine 16. La platine 16 est montée sur le capot 12, à l'arrière de celui-ci, de manière à fermer, en partie au moins, la face arrière du capot 12. La platine 16 est fixée au capot 12, par exemple par clipsage, comme ici en partie haute du boîtier 10, ou par vissage, comme ici en partie basse.The housing 10 further comprises a second elementary part shaped as a plate 16. The plate 16 is mounted on the cover 12, at the rear thereof, so as to close, in part at least, the rear face of the cover. 12. The plate 16 is fixed to the cover 12, for example by clipping, as here in the upper part of the housing 10, or by screwing, as here in the lower part.

Le capot 12 est ici généralement parallélépipédique. La platine 16 est généralement rectangulaire, en correspondance de forme avec le capot 12.The cover 12 is here generally parallelepipedal. The plate 16 is generally rectangular, corresponding in shape to the cover 12.

Le capot 12 présente une paroi supérieure 1200 et une paroi inférieure 1202 mutuellement opposées et qui forment respectivement une partie au moins de la face supérieure 160 et inférieure 170 du boîtier 10. Le capot 12 présente aussi une paroi de droite 1204 et une paroi de gauche 1206, mutuellement opposées et qui forment respectivement la face de droite 150 et la face de gauche 140 du boîtier 10, en partie au moins.The cover 12 has an upper wall 1200 and a lower wall 1202 which are mutually opposed and which respectively form a part at least of the upper 160 and lower 170 face of the housing 10. The cover 12 also has a right wall 1204 and a left wall. 1206, mutually opposed and which form respectively the right face 150 and the left face 140 of the housing 10, at least in part.

Dans le mode de réalisation illustré ici, le boîtier 10 comprend en outre une troisième pièce élémentaire conformée en un socle 14. Le socle 14 est généralement creux avec une face arrière qui forme la face arrière 130 du boîtier 10 et une face avant ouverte sur l'intérieur du socle 14. Le socle 14 est conformé en une coque.In the embodiment illustrated here, the housing 10 further comprises a third elementary part in the form of a base 14. The base 14 is generally hollow with a rear face which forms the rear face 130 of the housing 10 and a front face open to the bottom. 'Inside the base 14. The base 14 is shaped as a shell.

Le socle 14 est ici généralement parallélépipédique, en correspondance de forme avec la platine 16.The base 14 is here generally parallelepiped, corresponding in shape to the plate 16.

Le socle 14 est monté sur la face arrière du capot 12 par l'intermédiaire de sa face avant, avec intercalation de la platine 16. La platine 16 ferme, en partie au moins, la face avant du socle 14. En variante, le socle 14 est monté sur la face arrière de la platine 16.The base 14 is mounted on the rear face of the cover 12 via its front face, with the plate 16. The plate 16 closes, in part at least, the front face of the base 14. As a variant, the base 14 is mounted on the rear face of the plate 16.

Le socle 14 est agencé de manière à contribuer, en partie au moins, à la fixation du boîtier 10 contre la paroi. Ici par exemple, le socle 14 présente un ou plusieurs orifices débouchant sur sa face arrière et permettant le passage d'éléments de visserie.The base 14 is arranged so as to contribute, in part at least, to the fixing of the housing 10 against the wall. Here for example, the base 14 has one or more orifices opening out on its rear face and allowing the passage of fasteners elements.

Le socle 14 est destiné à une installation du déclencheur 1 du type dit "en saillie", où l'ensemble des éléments constitutifs du déclencheur 1 sont logés dans le boîtier, une partie au moins dans le socle 14.The base 14 is intended for an installation of the trigger 1 of the so-called "protruding" type, where all the constituent elements of the trigger 1 are housed in the housing, at least part in the base 14.

Ce socle 14 est facultatif. Le boîtier 10 peut être est dépourvu de socle 14. C'est le cas, en particulier, d'une installation du type dit "en applique", où une partie au moins des éléments constitutifs du déclencheur 1 se trouvent à l'extérieur du boîtier 10, le plus souvent logés dans un évidement ménagé dans la paroi. La platine 16 correspond alors à la face arrière 130 du boîtier 10. Pour ce faire, la platine 16 est configurée pour permettre la fixation du boîtier 10 à une paroi. Ici, par exemple la platine 16 est munie d'une paire de trous oblongs qui permettent le passage d'éléments de visserie.This base 14 is optional. The housing 10 may be without a base 14. This is the case, in particular, of an installation of the so-called "surface-mounted" type, where at least part of the components of the trip unit 1 are located outside the unit. housing 10, most often housed in a recess in the wall. The plate 16 then corresponds to the rear face 130 of the housing 10. To do this, the plate 16 is configured to allow the housing 10 to be fixed to a wall. Here, for example, the plate 16 is provided with a pair of oblong holes which allow the passage of fasteners.

Le déclencheur 1 comprend un mécanisme de déclenchement 20, logé dans le boîtier 10.The trigger 1 comprises a trigger mechanism 20, housed in the housing 10.

Le mécanisme 20 comprend une plaque-poussoir 22, montée de manière guidée en translation dans le boîtier 10, suivant la direction X. Cette plaque-poussoir 22 se trouve à proximité de la face avant 120 du boîtier 10. On accède à la plaque-poussoir 22 au travers de la première fenêtre 122. Ici, la plaque-poussoir 22 est montée dans le capot 12. Cette direction X correspond à la direction d'actionnement du déclencheur 1, i.e. la direction selon laquelle l'utilisateur doit presser la plaque-poussoir 22 pour déclencher.The mechanism 20 comprises a push plate 22, mounted in a guided manner in translation in the housing 10, in the direction X. This push plate 22 is located near the front face 120 of the housing 10. The plate is accessed. pusher 22 through the first window 122. Here, the pusher plate 22 is mounted in the cover 12. This direction X corresponds to the direction of actuation of the trigger 1, ie the direction in which the user must press the plate -pusher 22 to trigger.

La translation de la plaque-poussoir 22 relativement au boîtier 10 est contrainte par un organe de rappel élastique, ici un premier ressort de compression 26. Ce premier ressort 26 est disposé suivant la direction X, intercalé entre la plaque-poussoir 22 et la platine 16. En l'absence d'effort extérieur au déclencheur 1 sur la plaque-poussoir 22, du moins présentant une composante selon la direction X, la plaque-poussoir 22 repose en face avant du boîtier 10 sous l'effet du premier ressort 26.The translation of the push plate 22 relative to the housing 10 is constrained by an elastic return member, here a first compression spring 26. This first spring 26 is arranged in the X direction, interposed between the push plate 22 and the plate. 16. In the absence of any force external to the trigger 1 on the push plate 22, at least having a component in the direction X, the push plate 22 rests on the front face of the housing 10 under the effect of the first spring 26. .

Outre la plaque-poussoir 22, le mécanisme 20 comprend une plaque-coulisse 24 montée dans le boîtier 10 de manière guidée en translation suivant la direction Z. Ici, la plaque-coulisse 24 est montée dans le capot 12.In addition to the push plate 22, the mechanism 20 comprises a slide plate 24 mounted in the housing 10 in a guided manner in translation in the Z direction. Here, the slide plate 24 is mounted in the cover 12.

La translation de la plaque-coulisse 24 relativement au boîtier 10 est contrainte par un organe de rappel élastique, ici un second ressort de compression (non visible sur la figure 5), disposé selon la direction Z, entre la plaque-coulisse 24 et le capot 12. Le second ressort est situé en partie haute du boîtier 10. En variante, le second ressort pourrait aussi être installé dans une partie basse de ce boîtier 10.The translation of the slide plate 24 relative to the housing 10 is constrained by an elastic return member, here a second compression spring (not visible on the figure 5 ), arranged in the Z direction, between the slide plate 24 and the cover 12. The second spring is located in the upper part of the housing 10. As a variant, the second spring could also be installed in a lower part of this housing 10.

La plaque-poussoir 22 et la plaque-coulisse 24 sont en outre engagées l'une avec l'autre, de telle manière que dans une première position relative, la plaque-poussoir 22 empêche la translation de la plaque-coulisse 24 relativement au boîtier 10, le second ressort se trouvant dans un état fortement sollicité (ici comprimé) et, dans une seconde position relative, la plaque-poussoir 22 libère cette translation de la plaque-coulisse 24. La plaque-coulisse 24 se déplace suivant la direction Z sous l'effet du second ressort, jusqu'à rencontrer une butée 100, ici formée dans capot 12.The pusher plate 22 and the slide plate 24 are further engaged with each other, such that in a first relative position, the pusher plate 22 prevents translation of the slide plate 24 relative to the housing. 10, the second spring being in a highly stressed state (here compressed) and, in a second relative position, the push plate 22 releases this translation of the slide plate 24. The slide plate 24 moves in the Z direction under the effect of the second spring, until it meets a stop 100, here formed in cover 12.

La première position relative de la plaque-poussoir 22 et la plaque-coulisse 24 correspond à un premier état du mécanisme 20, où le déclencheur 1 est armé. La seconde position relative de la plaque-poussoir 22 et la plaque-coulisse 24 correspond à un second état du mécanisme 20, où le déclencheur 1 est déclenché.The first relative position of the push plate 22 and the slide plate 24 corresponds to a first state of the mechanism 20, where the trigger 1 is armed. The second relative position of the push plate 22 and the slide plate 24 corresponds to a second state of the mechanism 20, where the trigger 1 is triggered.

Le mécanisme 20 passe du premier état au second état consécutivement à un déplacement de la plaque-poussoir 22 suivant la direction X, dans un sens qui éloigne cette plaque-poussoir 22 de la face avant 120 du boîtier 10. Un tel déplacement comprime le premier ressort 26. Typiquement, ce déplacement correspond à l'appui d'un utilisateur.The mechanism 20 changes from the first state to the second state following a displacement of the push plate 22 in the direction X, in a direction which moves this push plate 22 away from the front face 120 of the housing 10. Such a displacement compresses the first one. spring 26. Typically, this displacement corresponds to the support of a user.

Les premier et second états du mécanisme 20 sont stables. En l'absence d'une intervention extérieure, le mécanisme 20 reste dans l'état dans lequel il est.The first and second states of mechanism 20 are stable. In the absence of an external intervention, the mechanism 20 remains in the state in which it is.

Le déclencheur 1 comprend en outre une électronique 40 logée dans le boîtier 10.The trip device 1 further comprises an electronics 40 housed in the housing 10.

L'électronique 40 présente un premier état, par exemple non active, et un second état, par exemple active. Par exemple, lorsqu'elle se trouve dans son état actif, l'électronique 40 génère le signal activant un élément de sécurité.The electronics 40 have a first state, for example not active, and a second state, for example active. For example, when it is in its active state, the electronics 40 generates the signal activating a security element.

L'électronique 40 comprend un commutateur à deux états, sous la forme d'un micro-rupteur 42 avec une partie mobile 420 qui sert de contact. La partie mobile 420 présente une position stable, où le d'un micro-rupteur 42 se trouve dans un premier état de commutation et une position instable, où le micro-rupteur 42 se trouve dans un second état de commutation.The electronics 40 include a two-state switch, in the form of a microswitch 42 with a movable part 420 which serves as a contact. The movable part 420 has a stable position, where the of a microswitch 42 is in a first switching state and an unstable position, where the microswitch 42 is in a second switching state.

Dans la position stable du micro-rupteur 42, l'électronique 40 se trouve dans son premier état, tandis que dans la position instable de ce micro-rupteur 42, l'électronique 40 est son second état.In the stable position of the microswitch 42, the electronics 40 is in its first state, while in the unstable position of this microswitch 42, the electronics 40 is its second state.

Lorsque le mécanisme 20 est armé, la partie mobile 420 du micro-rupteur 42 se trouve en position stable, libre de contrainte. À son déclenchement, le mécanisme 20 contraint la partie mobile 420 du micro-rupteur 42 dans son état instable.When the mechanism 20 is armed, the movable part 420 of the microswitch 42 is in a stable position, free of stress. When it is triggered, the mechanism 20 forces the movable part 420 of the microswitch 42 into its unstable state.

Ici, l'électronique 40 comprend deux micro-rupteurs 42, chacun d'eux étant destiné à être relié à un système respectif. Le déclencheur 1 peut ainsi agir simultanément sur deux systèmes plus étendus. Par exemple, l'un de ces systèmes peut être une porte coupe-feu, dont la fermeture est commandée par l'un des micro-rupteurs 42, et l'autre de ces systèmes peut être un système central, notifié d'un appui sur le déclencheur 1 par l'autre des micro-rupteurs 42.Here, the electronics 40 include two micro-switches 42, each of them being intended to be connected to a respective system. The trigger 1 can thus act simultaneously on two larger systems. For example, one of these systems can be a fire door, the closing of which is controlled by one of the microswitches 42, and the other of these systems can be a central system, notified of a press. on the release 1 by the other of the micro-switches 42.

Chaque micro-rupteur 42 est disposé à proximité du mécanisme de déclenchement 20, en particulier à proximité de la plaque-coulisse 24. Dans l'état armé du mécanisme de déclenchement 20, la plaque-coulisse 24 est à distance des micro-rupteurs 42, laissant la partie mobile 420 dans sa position stable. Dans l'état déclenché du mécanisme de déclenchement 20, la plaque-coulisse 24 est au contact des micro-rupteurs 42 et maintient la partie mobile 420 de chaque micro-rupteur 42 dans sa seconde position.Each microswitch 42 is disposed near the trigger mechanism 20, in particular near the slide plate 24. In the armed state of the trigger mechanism 20, the slide plate 24 is remote from the microswitches 42. , leaving the movable part 420 in its stable position. In the tripped state of the trigger mechanism 20, the slide plate 24 is in contact with the microswitches 42 and maintains the movable part 420 of each microswitch 42 in its second position.

En variante (non représentée sur les figures), l'électronique 40 pourrait comprendre un seul micro-rupteur. C'est généralement le cas lorsque le déclencheur 1 est pour un système d'alarme incendie.As a variant (not shown in the figures), the electronics 40 could include a single micro-switch. This is usually the case when trigger 1 is for a fire alarm system.

Ici, le socle 14 présente optionnellement au moins une paire de trous oblongs 1400, visibles sur la figure 5, en forme générale d'arc de cercle ou de demi-lune. Les formes en arc de cercle des trous oblongs 1400 sont agencées dans le socle de manière concentrique. Chacun des trous oblongs 1400 est élargi à l'une de ses extrémités 1402, comparé au reste dudit trou oblong 1400. Les trous oblongs 1400 peuvent être symétriques par rapport à un axe de symétrie parallèle à la direction X du boîtier 10. En variante, le socle 14 pourrait comprendre trois trous oblongs 1400 ou plus.Here, the base 14 optionally has at least one pair of oblong holes 1400, visible on the figure 5 , in the general shape of an arc of a circle or a half-moon. The circular arc shapes of the oblong holes 1400 are arranged in the base in a concentric manner. Each of the oblong holes 1400 is widened at one of its ends 1402, compared to the rest of said oblong hole 1400. The oblong holes 1400 may be symmetrical with respect to an axis of symmetry parallel to the X direction of the housing 10. Alternatively, the base 14 could include three oblong holes 1400 or more.

Dans certains cas, la paroi comprend un pot d'encastrement (non visible sur les figures) généralement tubulaire, typiquement moulé avec la paroi. Le pot débouche à une extrémité sur la paroi, permettant de faire passer dans cette paroi les câbles reliant l'électronique 40 au système pour lequel le déclencheur 1 est prévu. Le déclencheur 1 est installé à l'extrémité du pot et l'électronique 40 est reliée aux câbles. Le pot comprend en outre autant de filetages pour vis que de le socle comprend de trous oblongs 1400.In some cases, the wall comprises a generally tubular recessing pot (not visible in the figures), typically molded with the wall. The pot opens at one end on the wall, allowing the cables connecting electronics 40 to the system for which the trip unit 1 is provided. The trigger 1 is installed at the end of the pot and the electronics 40 are connected to the cables. The pot further comprises as many screw threads as the base has oblong holes 1400.

Avant le montage du boîtier 10 sur la paroi, une vis est vissée dans chacun des filetages du pot. Au montage, le socle 14 est placé à l'extrémité du pot, et chacune des têtes de ces vis traverse l'extrémité 1402 élargie de l'un des trous oblongs 1400. Le socle 14 est ensuite pivoté autour de l'axe de symétrie des trous oblongs 1400, jusqu'à ce que la direction Y du boîtier 10 soit à l'horizontale. La tige de chacune des vis est en prise avec le reste du trou oblong 1400. Les vis sont ensuite vissées de sorte à plaquer le socle 14 contre la paroi et/ou contre l'extrémité du pot.Before mounting the housing 10 on the wall, a screw is screwed into each of the threads of the pot. During assembly, the base 14 is placed at the end of the pot, and each of the heads of these screws passes through the end 1402 widened by one of the oblong holes 1400. The base 14 is then pivoted around the axis of symmetry. oblong holes 1400, until the Y direction of the housing 10 is horizontal. The shank of each of the screws is engaged with the rest of the oblong hole 1400. The screws are then screwed so as to press the base 14 against the wall and / or against the end of the pot.

Les trous oblongs 1400 permettent de fixer le boîtier 10 à la paroi sans avoir à enlever ou installer de vis supplémentaire. L'installation du boîtier 10 est simplifiée par rapport à un montage où le socle 14 est directement vissé à la paroi.Slotted holes 1400 allow housing 10 to be secured to the wall without having to remove or install additional screws. The installation of the housing 10 is simplified compared to an assembly where the base 14 is directly screwed to the wall.

La forme en arc de cercle des trous oblongs 1400 permet de régler facilement l'inclinaison du boîtier 10 à l'horizontale. Le boîtier 10 se fixe aisément à la paroi et son horizontalité ne dépend pas de l'orientation du pot, dont les deux filetages peuvent ne pas être au même niveau l'un que l'autre.The arcuate shape of the oblong holes 1400 makes it easy to adjust the inclination of the housing 10 horizontally. The housing 10 is easily fixed to the wall and its horizontality does not depend on the orientation of the pot, the two threads of which may not be at the same level as one another.

La platine 16 peut également comprendre deux trous oblongs 1600, analogues à ceux du socle 14, chacun avec une extrémité 1602 élargie par rapport au reste dudit trou oblong 1600. Cela permet de fixer la platine 16 avec le socle 14 aux vis du pot. La fixation du boîtier 10 est plus sûre.The plate 16 may also include two oblong holes 1600, similar to those of the base 14, each with an end 1602 enlarged with respect to the rest of said oblong hole 1600. This allows the plate 16 to be fixed with the base 14 to the screws of the pot. The fixing of the housing 10 is more secure.

On fait référence aux figures 6 à 9.We refer to figures 6 to 9 .

La plaque-poussoir 22 comprend une plaque principale 220 et une portion agencée en un organe de blocage de la plaque-coulisse 24, ou portion de retenue 224, maintenue en saillie d'un côté de la plaque principale 220 par une portion de liaison 222, ici adjacente à la portion de retenue 224. La portion de liaison 222 et la portion de retenue 224 sont ici agencées sensiblement au centre de la plaque principale 220.The push plate 22 comprises a main plate 220 and a portion arranged as a blocking member of the slide plate 24, or retaining portion 224, held projecting from one side of the main plate 220 by a connecting portion 222. , here adjacent to the retaining portion 224. The connecting portion 222 and the retaining portion 224 are here arranged substantially at the center of the main plate 220.

Ici, la plaque principale 220, la portion de retenue 224 et la portion de liaison 222 sont réalisées d'un seul tenant, sous la forme de sections respectives d'une portion de la plaque-poussoir 22 en forme de colonne 234. Une première section de cette colonne 234, ou section d'extrémité, correspond à la portion de retenue 224, tandis qu'une seconde section, adjacente à la première, correspond à la portion de liaison 222. La colonne 234 est ici agencée au centre de la plaque principale 220. La colonne 234 s'étend ici le long d'un axe d'alignement 226 perpendiculaire à la plaque principale 220.Here, the main plate 220, the retaining portion 224 and the link portion 222 are made integrally, as respective sections of a portion of the column-shaped push plate 22 234. A first section of this column 234, or end section, corresponds to the retaining portion 224, while a second section, adjacent to the first, corresponds to the connecting portion 222. The column 234 is here arranged at the center of the main plate 220. Column 234 here extends along an alignment axis 226 perpendicular to main plate 220.

La plaque-poussoir 22 est montée dans le boîtier 10 de telle sorte que la plaque principale 220 soit disposée parallèlement à la face avant 120 du boîtier 10 et la portion de retenue 224 dirigée vers la face arrière 130 de ce boîtier 10. La plaque principale 220 est généralement rectangulaire. La plaque-poussoir 22 est montée dans le boîtier 10 de telle sorte l'une de ses dimensions, longueur ou largeur, suive la direction Z, l'autre à la direction Y.The push plate 22 is mounted in the housing 10 such that the main plate 220 is disposed parallel to the front face 120 of the housing 10 and the retaining portion 224 directed towards the rear face 130 of this housing 10. The main plate 220 is generally rectangular. The push plate 22 is mounted in the housing 10 such that one of its dimensions, length or width, follows the Z direction, the other in the Y direction.

La portion de liaison 222 et la portion de retenue 224 présentent chacune une première étendue selon une direction parallèle au plan de la plaque principale 220. Cette direction est perpendiculaire à la direction de translation de la plaque-poussoir 22 relativement au boîtier 10 et à la direction de translation de la plaque-coulisse 24 relativement à ce boîtier 10, la direction Y. Cette étendue correspond respectivement à une largeur W1 de la portion de liaison 222 et une largeur W2 de la portion de retenue 224. La largeur W1 est inférieure à la seconde largeur W2.The connecting portion 222 and the retaining portion 224 each have a first extent in a direction parallel to the plane of the main plate 220. This direction is perpendicular to the direction of translation of the push plate 22 relative to the housing 10 and to the direction of translation of the slide plate 24 relative to this housing 10, the direction Y. This extent corresponds respectively to a width W1 of the connecting portion 222 and a width W2 of the retaining portion 224. The width W1 is less than the second width W2.

La portion de liaison 222 et la portion de retenue 224 présentent chacune une seconde étendue selon une direction parallèle au plan de la plaque principale 220.

The link portion 222 and the first spring 26 are aligned in the X direction along an alignment axis 226.

Les spires du premier ressort 26 sont enfilées autour du premier doigt 230. Une extrémité du premier ressort 26 vient en appui contre la paroi latérale 2300 du premier doigt 230. Cet appui est sensiblement linéique, selon un cercle centré sur l'axe d'alignement 226. Le premier doigt 230 maintient en outre le premier ressort 26 dans le premier siège 221. Cela simplifie le montage du mécanisme 20 et en améliore la stabilité, sans en augmenter l'encombrement.The turns of the first spring 26 are threaded around the first finger 230. One end of the first spring 26 bears against the side wall 2300 of the first finger 230. This support is substantially linear, in a circle centered on the alignment axis 226. The first finger 230 further maintains the first spring 26 in the first seat 221. This simplifies the assembly of the mechanism 20 and improves its stability, without increasing its bulk.

Le second siège 241 reçoit le second ressort 28. Le second ressort 28 s'appuie contre le fond de l'évidement 2500 et contre la plateforme 2410 de la plaque-coulisse 24. Les spires du second ressort 28 sont enfilées autour du second doigt 250. Le second doigt 250 maintient le second ressort 28 dans le second siège 241. L'encombrement du mécanisme 20 en est réduit. Le mécanisme 20 est en outre plus stable et plus simple à assembler.The second seat 241 receives the second spring 28. The second spring 28 rests against the bottom of the recess 2500 and against the platform 2410 of the slide plate 24. The turns of the second spring 28 are threaded around the second finger 250 The second finger 250 maintains the second spring 28 in the second seat 241. The size of the mechanism 20 is thereby reduced. The mechanism 20 is also more stable and easier to assemble.

La portion de contact 252 est en regard des parties mobiles 420 des micro-rupteurs 42, de sorte à appuyer sur ces parties mobiles 420 lorsque le mécanisme 20 est dans l'état déclenché.The contact portion 252 is opposite the movable parts 420 of the microswitches 42, so as to press on these movable parts 420 when the mechanism 20 is in the triggered state.

Dans l'état déclenché, la portion de liaison 222 traverse la portion étroite 242. La portion de retenue 224 se trouve au-delà de la plaque-coulisse 24 dans la direction de compression du premier ressort 26. La portion de liaison 222 se trouve engagée en travers de la plaque-coulisse 24, dans la portion étroite 244.In the tripped state, the connecting portion 222 passes through the narrow portion 242. The retaining portion 224 is located beyond the slide plate 24 in the direction of compression of the first spring 26. The connecting portion 222 is located. engaged across the slide plate 24, in the narrow portion 244.

La portion de contact 252 vient contre le micro-rupteur 42 et maintient la partie mobile 420 du micro-rupteur 42 dans sa position instable. L'électronique 40 est active.The contact portion 252 comes against the microswitch 42 and maintains the movable part 420 of the microswitch 42 in its unstable position. Electronics 40 is active.

Dans l'état armé, la plaque-poussoir 22 est maintenue en butée contre la face avant 120 du boîtier 10 par l'action du premier ressort 26 dans la direction X vers l'avant du boîtier 10. La portion de retenue 224 de la plaque-poussoir 22 se trouve au niveau de la plaque de retenue 24 dans la direction X, en prise dans la grande portion 242 du trou oblong 240. La portion de retenue 224 est plus large que la portion étroite 244 en sorte que la portion de retenue 224 ne peut s'engager dans la portion étroite 244. La portion de retenue 224 se trouve, en partie au moins, en butée contre l'épaulement 246. La plaque-poussoir 22 interdit la translation de la plaque-coulisse 24 relativement au boîtier 10, notamment sous l'effet du second ressort 28. La portion de contact 252 de la plaque-coulisse 24 est à distance du micro-rupteur 42, laissant la partie mobile 420 dans sa position stable. L'électronique 40 est non active.In the armed state, the push plate 22 is held in abutment against the front face 120 of the housing 10 by the action of the first spring 26 in the direction X towards the front of the housing 10. The retaining portion 224 of the pusher plate 22 is at the retaining plate 24 in the X direction, engaging the large portion 242 of the elongated hole 240. The retaining portion 224 is wider than the narrow portion 244 so that the locking portion retainer 224 cannot engage in the narrow portion 244. The portion retainer 224 is located, in part at least, in abutment against the shoulder 246. The push plate 22 prevents the translation of the slide plate 24 relative to the housing 10, in particular under the effect of the second spring 28. The portion contact 252 of the slide plate 24 is remote from the microswitch 42, leaving the movable part 420 in its stable position. Electronics 40 is not active.

L'état armé est maintenu tant qu'une pression suffisamment élevée pour vaincre le premier ressort 26 n'est pas appliquée sur la plaque-poussoir 22. Le passage de l'état armé à l'état déclenché du mécanisme 20 se fait comme suit.The armed state is maintained as long as a pressure high enough to overcome the first spring 26 is not applied to the push plate 22. The change from the armed state to the triggered state of the mechanism 20 is as follows .

Lorsqu'une pression suffisamment élevée est appliquée, celle-ci déplace la plaque-poussoir 22 jusqu'à ce que la portion de retenue 224 traverse la portion large 242. La plaque de retenue 224 se trouve dégagée de la portion large 242. La plaque-poussoir 22 ne bloque plus la translation de la plaque-coulisse 24 relativement au boîtier 10. Le second ressort 28 pousse la plaque-coulisse 24 jusqu'à ce que celle-ci appuie sur les portions mobiles 420 des micro-rupteurs 42 (ici par l'intermédiaire des ergots 2520 et 2522). Le mécanisme 20 est dans l'état déclenché.When a sufficiently high pressure is applied, it moves the push plate 22 until the retaining portion 224 passes through the wide portion 242. The retaining plate 224 is disengaged from the wide portion 242. The plate -pusher 22 no longer blocks the translation of the slide plate 24 relative to the housing 10. The second spring 28 pushes the slide plate 24 until the latter presses on the movable portions 420 of the microswitches 42 (here via pins 2520 and 2522). Mechanism 20 is in the triggered state.

La portion de retenue 224 est suffisamment étroite pour pouvoir traverser la portion large 242. Au déclenchement, c'est-à-dire lorsqu'un utilisateur appuie sur la plaque-pression 22, la portion de retenue 224 est translatée au-delà de la plaque-coulisse 24, hors de la portion large 242.The retaining portion 224 is narrow enough to be able to pass through the wide portion 242. On release, that is to say when a user presses on the pressure plate 22, the retaining portion 224 is translated beyond the limit. slide plate 24, out of the wide portion 242.

La portion de liaison 222 s'engage dans la portion large 242. La translation de la plaque-coulisse 24 relativement au boîtier 10 est libérée. La plaque-coulisse 24 est libre de coulisser relativement à la plaque-poussoir 22 dans la direction d'alignement de la portion large 242 et de la portion étroite 244.The connecting portion 222 engages in the wide portion 242. The translation of the slide plate 24 relative to the housing 10 is released. The slide plate 24 is free to slide relative to the pusher plate 22 in the direction of alignment of the wide portion 242 and the narrow portion 244.

Le second ressort 28 pousse la plaque-coulisse 24 dans sa direction de translation, jusqu'à la butée 100. La portion de liaison 222 coulisse dans la portion large 242 et dans la portion étroite 244, jusqu'à venir contre la butée 100.The second spring 28 pushes the slide plate 24 in its direction of translation, up to the stop 100. The connecting portion 222 slides in the wide portion 242 and in the narrow portion 244, until it comes against the stop 100.

La plaque-poussoir 22 et la plaque-coulisse 24 sont alors dans leur seconde position relative. La portion de liaison 222 traverse la portion étroite 244.The push plate 22 and the slide plate 24 are then in their second relative position. The connecting portion 222 passes through the narrow portion 244.

L'actionnement est particulièrement stable, malgré l'action d'un unique ressort. Le montage du mécanisme 20 est amélioré. La compacité de la plaque-poussoir 22 est en outre meilleure que dans des déclencheurs classiques. La plaque-poussoir 22 est de conception plus robuste. Cela permet en outre d'utiliser un seul ressort pour réaliser l'organe élastique contraignant la plaque-poussoir 22, ce qui est plus économique.The actuation is particularly stable, despite the action of a single spring. The assembly of the mechanism 20 is improved. The compactness of the push plate 22 is also better than in conventional triggers. The push plate 22 is of a more robust design. This also makes it possible to use a single spring to produce the elastic member constraining the push plate 22, which is more economical.

L'état déclenché est maintenu tant que le mécanisme 20 n'est pas réarmé. Le passage de l'état déclenché à l'état armé du mécanisme 20, c'est-à-dire le réarmement, se fait comme suit.The triggered state is maintained as long as the mechanism 20 is not reset. The transition from the triggered state to the armed state of the mechanism 20, that is to say the rearming, takes place as follows.

La plaque-coulisse 24 comprend ici une portion destinée au réarmement 254. La portion de réarmement 254 coopère ici avec une clef 30 (visible sur la figure 1) pour réarmer le déclencheur 1, c'est-à-dire pour ramener le mécanisme 20 dans son premier état.The slide plate 24 here comprises a portion intended for rearming 254. The rearming portion 254 here cooperates with a key 30 (visible on the figure 1 ) to reset the trigger 1, that is to say to return the mechanism 20 to its first state.

La clef 30 peut être commune à plusieurs déclencheurs. La clef 30 comprend ici un corps 32 servant à l'agripper et deux pattes 36 et 38 parallèles, à distance l'une de l'autre et faisant saillie d'un côté du corps 32. Les pattes 36 et 38 forment la partie fonctionnelle 34 de la clef, et sont ici en forme de rampe avec une section transversale en L qui décroît à mesure que l'on s'éloigne du corps 32. La portion de réarmement 254 prend ici la forme de deux ergots 2540 et 2542 conformés chacune en une rampe, dont la pente est complémentaire à la pente des rampes des pattes 36 et 38 de la clef 30, respectivement.The key 30 can be common to several triggers. The key 30 here comprises a body 32 serving to grip it and two parallel legs 36 and 38, at a distance from each other and projecting from one side of the body 32. The legs 36 and 38 form the functional part. 34 of the key, and are here in the form of a ramp with an L-shaped cross section which decreases as one moves away from the body 32. The reset portion 254 here takes the form of two lugs 2540 and 2542 each shaped in a ramp, the slope of which is complementary to the slope of the ramps of the legs 36 and 38 of the key 30, respectively.

Le réarmement du mécanisme 20 se fait par introduction de la clef 30 dans un accès 126 (visible sur les figures 1 et 2) ménagé dans le capot 12. Ici, l'accès 126 est ménagé sur la paroi avant 120 du capot 12. En variante, l'accès 126 pourrait être ménagé sur la face inférieure du capot 12. L'accès 126 peut être de forme complémentaire à celle des pattes 36 et 38, comme dans le mode de réalisation décrit ici, ou, en variante, plus grand que la portion de réarmement 34. Ici, l'accès 126 comprend deux ouvertures traversantes 1260 et 1262 en L disposées symétriquement autour du plan VI-VI.The mechanism 20 is reset by inserting the key 30 into an access 126 (visible on the figures 1 and 2 ) provided in the cover 12. Here, the access 126 is made on the front wall 120 of the cover 12. As a variant, the access 126 could be made on the underside of the cover 12. The access 126 can be shaped. complementary to that of the legs 36 and 38, as in the embodiment described here, or, alternatively, more larger than the rearming portion 34. Here, the access 126 comprises two through openings 1260 and 1262 in L arranged symmetrically around the plane VI-VI.

L'introduction de la clef 30 dans l'accès 126 pousse la plaque-coulisse 24 contre le second organe élastique, ce qui fait translater la plaque-coulisse 24 jusqu'à l'état armé. Le mécanisme 20 reste dans l'état armé lorsque la clef 30 est retirée.The introduction of the key 30 in the access 126 pushes the slide plate 24 against the second elastic member, which translates the slide plate 24 to the armed state. The mechanism 20 remains in the armed state when the key 30 is withdrawn.

Lors du réarmement, la clef 30 est introduite dans une ouverture 126 du capot 12 suivant la direction X. La plaque-coulisse 24 se trouve alors poussée dans la direction Z à l'encontre du second ressort 28, jusqu'à ce que la portion large 242 du trou oblong 240 se trouve au niveau de la portion de retenue 224 du poussoir 22. Le premier ressort 26 pousse alors la plaque-poussoir 22 dans la direction X vers l'avant du boîtier 10. La portion de retenue 224 traverse la portion large 242 du trou oblong 240, ce qui bloque la translation de la plaque-coulisse 24 dans la direction Z. Le mécanisme 20 est alors dans l'état armé.When resetting, the key 30 is inserted into an opening 126 of the cover 12 in the X direction. The slide plate 24 is then pushed in the Z direction against the second spring 28, until the portion The wide 242 of the oblong hole 240 is at the retaining portion 224 of the pusher 22. The first spring 26 then pushes the pusher plate 22 in the X direction towards the front of the housing 10. The retaining portion 224 passes through the wide portion 242 of the oblong hole 240, which blocks the translation of the slide plate 24 in the Z direction. The mechanism 20 is then in the armed state.

En variante, la plaque-coulisse 24 pourrait être dépourvue d'une portion de réarmement 252, et la clef 30 pourrait être introduite par la paroi inférieure 1202 (à l'opposé du second ressort 28) et pousser directement la plaque-coulisse 24 afin de réarmer le mécanisme de déclenchement.Alternatively, the slide plate 24 could be devoid of a reset portion 252, and the key 30 could be introduced through the bottom wall 1202 (opposite the second spring 28) and directly push the slide plate 24 in order reset the trigger mechanism.

Il a été vu un mécanisme de déclenchement 20 comprenant une plaque-poussoir 22. On pourrait en variante imaginer un poussoir d'une autre forme, en particulier avec une face avant non plane, par exemple pour améliorer le guidage en translation du poussoir, ou avec une dépression centrale pour inciter les utilisateurs à appuyer au centre du poussoir.It has been seen a trigger mechanism 20 comprising a pusher plate 22. As a variant, one could imagine a pusher of another shape, in particular with a non-planar front face, for example to improve the guiding in translation of the pusher, or with a central depression to encourage users to press in the center of the pusher.

Il a été décrit que l'état instable des micro-rupteurs 42 correspond à l'état déclenché, mais on pourrait envisager l'inverse en variante.It has been described that the unstable state of the microswitches 42 corresponds to the triggered state, but the reverse could be considered as a variant.

La plaque-coulisse 24 translate à la verticale, le long de la direction Z. Cependant, le mécanisme 20 pourrait être agencé pour que la plaque de translation 24 translate le long de la direction Y, c'est-à-dire de gauche à droite et vice-versa.The slide plate 24 translates vertically, along the Z direction. However, the mechanism 20 could be arranged so that the translation plate 24 translates along the Y direction, i.e. from left to left. right and vice versa.

Dans le mode de réalisation qui a été décrit ici, le second ressort 28 fonctionne en compression. Cependant, on pourrait envisager un second ressort 28 fonctionnant en traction. Dans cette variante, la grande portion 242 et la petite portion 244 du trou oblong 240 sont disposés de sorte que la grande portion 242 soit plus proche du second siège 241 que la petite portion 244.In the embodiment which has been described here, the second spring 28 operates in compression. However, one could consider a second spring 28 operating in tension. In this variation, the large portion 242 and the small portion 244 of the oblong hole 240 are arranged so that the large portion 242 is closer to the second seat 241 than the small portion 244.

Dans le mode de réalisation décrit ici, la portion de retenue 224 présente une épaisseur qui décroît dans la direction Z de manière à conformer cette portion selon un profil de chanfrein, ou premier chanfrein 232. Ce premier chanfrein 232 se trouve en regard de la plaque principale 220. La plaque-poussoir 22 est montée dans le boîtier 10 de telle sorte que la partie épaisse de la portion de retenue 224 se trouve dirigée vers le second ressort 28.In the embodiment described here, the retaining portion 224 has a thickness which decreases in the Z direction so as to conform this portion according to a chamfer profile, or first chamfer 232. This first chamfer 232 is located opposite the plate. main 220. The pusher plate 22 is mounted in the housing 10 such that the thick part of the retaining portion 224 is directed towards the second spring 28.

Le premier chanfrein 232 diminue les frottements entre la plaque-coulisse 24 et la plaque-poussoir 22 lors du déclenchement ou du réarmement du déclencheur manuel 1. La plaque-coulisse 24 et la plaque-poussoir 22 glissent mieux l'une par rapport à l'autre lorsque la portion de retenue 224 est translatée au-delà de la plaque-coulisse 24. Le déclenchement du mécanisme 20 est plus franc et le réarmement plus aisé.The first chamfer 232 reduces the friction between the slide plate 24 and the push plate 22 when triggering or resetting the manual call point 1. The slide plate 24 and the push plate 22 slide better with respect to one another. 'other when the retaining portion 224 is translated beyond the slide plate 24. The triggering of the mechanism 20 is more straightforward and the rearming easier.

La plaque-coulisse 24 présente une épaisseur qui augmente en direction du second siège 241 depuis l'épaulement 246 de manière à conformer la plaque-coulisse 24 en un profil de chanfrein, ou second chanfrein 248. Le second chanfrein 248 est formé sur une face de la plaque-coulisse 24 en regard de la portion de retenue 224 lorsque le mécanisme 20 est assemblé.The slide plate 24 has a thickness which increases towards the second seat 241 from the shoulder 246 so as to shape the slide plate 24 into a chamfer profile, or second chamfer 248. The second chamfer 248 is formed on one face. of the slide plate 24 facing the retaining portion 224 when the mechanism 20 is assembled.

Le second chanfrein 248 réduit la course de la plaque-poussoir 22 nécessaire pour déclencher le mécanisme 20, sans avoir à réduire l'épaisseur de la plaque-coulisse 24 pour autant. Le déclenchement est plus aisé. En outre, ce déclenchement est plus fiable en cas de pression excentrée d'un utilisateur sur la plaque-poussoir 22.The second chamfer 248 reduces the stroke of the push plate 22 required to trigger the mechanism 20, without having to reduce the thickness of the slide plate 24. Triggering is easier. In addition, this triggering is more reliable in the event of eccentric pressure from a user on the push plate 22.

Dans un mode de réalisation, le boîtier 10 comprend sur l'une de ses faces latérales un orifice 44 (visible sur la figure 3). Cet orifice 44 permet l'accès aux micro-rupteurs 42 de l'électronique 40 depuis l'extérieur afin de faire jouer les contacts desdits micro-rupteurs 42. Cela permet de tester le bon fonctionnement de l'électronique 40 sans démonter le boîtier 10 lors d'essais de routine. L'orifice peut être fermé par un capuchon, non visible sur les figures.In one embodiment, the housing 10 comprises on one of its lateral faces an orifice 44 (visible on the figure 3 ). This orifice 44 allows access to the micro-switches 42 of the electronics 40 from the outside in order to play the contacts of said micro-switches 42. This makes it possible to test the correct operation of the electronics 40 without dismantling the housing 10 during routine tests. The orifice can be closed by a cap, not visible in the figures.

L'orifice 44 peut être légèrement excentré par rapport au plan VI-VI, comme cela est visible sur la figure 3. Cela permet, lorsque l'électronique 40 ne comprend qu'un seul micro-rupteur 42, que l'orifice 44 soit en face dudit micro-rupteur 42. L'orifice 44 peut alors être de taille réduite sans compromettre l'accès au micro-rupteur 42.The orifice 44 may be slightly eccentric with respect to the plane VI-VI, as can be seen on the figure 3 . This allows, when the electronics 40 only include a single microswitch 42, that the orifice 44 is opposite said microswitch 42. The orifice 44 can then be of reduced size without compromising access to the microphone. -switch 42.

En variante l'orifice 44 pourrait être centré et plus large. Cela permet de tester le bon fonctionnement de l'électronique 40 par un unique orifice 44, que l'électronique 40 comprenne un ou plusieurs micro-rupteurs 42.As a variant, the orifice 44 could be centered and wider. This makes it possible to test the correct operation of the electronics 40 through a single orifice 44, whether the electronics 40 include one or more microswitches 42.

Il a été décrit un premier siège 221 du type à doigt tronconique (où le premier ressort s'appuie contre la surface latérale du doigt) et un second siège 241 du type à fond plat (où le second ressort s'appuie contre un fond plat, ici formé du fond de l'évidement 2500 et de la plateforme 2410). En variante, le premier siège 221 pourrait du type à fond plat (avec ou sans doigt optionnel) et/ou le second siège 241 pourrait être du type à doigt tronconique.A first seat 221 of the frustoconical finger type has been described (where the first spring rests against the lateral surface of the finger) and a second seat 241 of the flat bottom type (where the second spring rests against a flat bottom , here formed of the bottom of the recess 2500 and of the platform 2410). As a variant, the first seat 221 could be of the flat bottom type (with or without optional finger) and / or the second seat 241 could be of the frustoconical finger type.

Le déclencheur manuel 1 peut être installé dans un système de sécurité de plus grande ampleur, tel qu'un dispositif d'alarme incendie, une porte automatique, une porte coupe-feu, un plan particulier de mise en sécurité (PPMS) ou un dispositif de désenfumage. Lorsque le déclencheur manuel 1 est actionné, il réalise une fonction de déclenchement, c'est-à-dire une action au sein du système de sécurité. Dans l'un des systèmes décrits ci-dessus, cette fonction de déclenchement peut être l'émission d'un signal d'alarme radio au dispositif d'alarme incendie, le déverrouillage de la porte automatique, la fermeture de la porte coupe-feu, un signal d'alarme au PPMS ou l'actionnement du dispositif de désenfumage.The manual call point 1 can be installed in a larger security system, such as a fire alarm device, an automatic door, a fire door, a special safety plan (PPMS) or a device. smoke extraction. When the manual trip unit 1 is actuated, it performs a trip function, that is to say an action within the safety system. In one of the systems described above, this triggering function can be the emission of a radio alarm signal to the fire alarm device, the automatic door unlocking, the closing of the fire door. , an alarm signal to the PPMS or the actuation of the smoke extraction device.
