Description

DISPOSITIF DE SECURISATION DE BOITIER, BOITIER ET DETECTEUR INCORPORANTHOUSING SECURING DEVICE, HOUSING AND DETECTOR INCORPORATING
UN TEL DISPOSITIFONE SUCH DEVICE
La présente invention concerne un dispositif de sécurisation pour boîtier, un boîtier et un détecteur incorporant un tel dispositif. Elle s'applique, en particulier aux boîtiers de détecteur, par exemple de détecteur de fumée, de chaleur ou d'incendie, dit « autonome » parce qu'ils comportent leur propre alimentation électrique, sous la forme d'une pile électrique. Pour des raisons de sécurité, les boîtiers de détecteurs de fumées doivent, conformément à des normes ou règlements nationaux ou internationaux, interdire que l'utilisateur puisse les refermer ou les assembler avec leur socle si la pile électrique est absente.The present invention relates to a device for securing a housing, a housing and a detector incorporating such a device. It applies, in particular detector housings, for example smoke detector, heat or fire, said "autonomous" because they include their own power supply, in the form of an electric battery. For safety reasons, the smoke detector housings must, in accordance with national or international standards or regulations, prohibit the user from being able to close them or assemble them with their base if the electric battery is not present.
Il est connu de prévoir une sorte de serrure coulissante comportant un ressort actionné par l'introduction de la pile dans un logement pour déplacer une pièce coulissante afin que cette pièce interdise la fermeture du boîtier en l'absence de la pile.It is known to provide a kind of sliding lock comprising a spring actuated by the introduction of the battery in a housing for moving a sliding part so that this part prohibits the closure of the housing in the absence of the battery.
Ce type de système est complexe, onéreux, proportionnellement au prix de revient d'un boîtier qui n'en est pas muni et présente des risques d'inefficacité lorsque le mécanisme vieillit, s'oxyde ou s'encrasse. Ce type de système ne rend donc pas le service attendu sur un long terme et peut mettre des personnes en danger.This type of system is complex, expensive, proportionally to the cost of a housing that is not equipped and presents risks of inefficiency when the mechanism ages, oxidizes or clogs. This type of system does not render the service expected over a long term and can put people at risk.
La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these disadvantages.
A cet effet, la présente invention vise, selon un premier aspect, un dispositif de sécurisation de boîtier pour garantir la présence d'une pile lorsque le boîtier est fermé, caractérisé en ce qu'il comporte : - un socle muni d'au moins une lame souple mobile entre une position au repos dans laquelle la lame souple dépasse d'une surface dudit socle et une position contrainte dans laquelle la lame souple ne dépasse pas de ladite surface et une pièce comportant un logement de pile et un moyen de fixation de ladite pièce sur ledit socle, ledit moyen de fixation imposant le passage dudit logement de pile en regard de ladite lame souple lors de la fermeture dudit boîtier.For this purpose, the present invention aims, in a first aspect, a housing securing device to ensure the presence of a battery when the housing is closed, characterized in that it comprises: - a base provided with at least a flexible blade movable between a rest position in which the flexible blade protrudes from a surface of said base and a constrained position in which the flexible blade does not protrude from said surface and a part comprising a battery housing and a fixing means of said piece on said base, said fixing means imposing the passage of said battery housing opposite said flexible blade when closing said housing.
Grâce à ces dispositions, lorsque la pile est absente, lors d'une tentative de fermeture du boîtier et donc de fixation de la pièce sur le socle, le logement de pile passe en regard de ladite lame qui, du fait de l'absence de la pile, est dans sa position au repos et bloque le mouvement de fixation. Au contraire, lorsque la pile est présente, la lame souple prend sa position contrainte et ne bloque donc pas le mouvement de fixation, ce qui permet la fermeture du boîtier. Selon des caractéristiques particulières, le socle est une pièce moulée intégrant au moins une lame souple mobile.Thanks to these arrangements, when the battery is absent, when an attempt is made to close the housing and thus to fix the part on the base, the battery housing passes next to said blade which, due to the absence of the battery, is in its rest position and blocks the fixing movement. On the contrary, when the battery is present, the flexible blade takes its constrained position and therefore does not block the fixing movement, which allows the closure of the housing. According to particular features, the base is a molded part incorporating at least one movable flexible blade.
Grâce à ces dispositions, le socle et la lame souple sont de fabrication aisée et forment une seule pièce.With these provisions, the base and the flexible blade are easy to manufacture and form a single piece.
Selon des caractéristiques particulières, au moins une lame souple présente, dans sa position de repos, une forme incurvée vers le socle.According to particular features, at least one flexible blade has, in its rest position, a curved shape towards the base.
Grâce à ces dispositions, lorsque la lame souple se trouve dans la position contrainte, son extrémité est tournée vers le socle et ne risque pas de s'accrocher sur la pièce en mouvement de fermeture.Thanks to these provisions, when the flexible blade is in the stressed position, its end is turned towards the base and is not likely to catch on the part in closing movement.
Selon des caractéristiques particulières, la pièce est adaptée à tourner sur le socle pour que le moyen de fixation rende ladite pièce solidaire du socle et au moins une lame souple est orientée tangentiellement par rapport à un cercle dont le centre est le centre de rotation de la pièce sur le socle.According to particular features, the part is adapted to rotate on the base so that the fastening means makes said part integral with the base and at least one flexible blade is oriented tangentially with respect to a circle whose center is the center of rotation of the piece on the base.
Grâce à ces dispositions, la fixation de la pièce sur le socle est aisée, par simple rotation ou vissage. Selon des caractéristiques particulières, le socle présente une forme généralement circulaire et comporte deux lames souples diamétralement opposées.Thanks to these arrangements, the attachment of the part on the base is easy, by simple rotation or screwing. According to particular features, the base has a generally circular shape and has two diametrically opposed flexible blades.
La présente invention vise, selon un deuxième aspect, un boîtier, caractérisé en ce qu'il comporte un dispositif de sécurisation tel que succinctement exposé ci-dessus.The present invention aims, in a second aspect, a housing, characterized in that it comprises a securing device as briefly described above.
La présente invention vise, selon un troisième aspect, un détecteur, caractérisé en ce qu'il comporte un boîtier tel que succinctement exposé ci-dessus et un capteur de grandeur physique.The present invention aims, in a third aspect, a detector, characterized in that it comprises a housing as briefly described above and a physical magnitude sensor.
Selon des caractéristiques particulières, la grandeur physique est la présence ou le niveau de fumée, de la chaleur et/ou de monoxyde de carbone ou une combinaison de ces éléments. Les avantages, buts et caractéristiques particulières de ce boîtier et de ce détecteur étant similaires à ceux du procédé tel que succinctement exposé ci-dessus, ils ne sont pas rappelés ici.According to particular characteristics, the physical quantity is the presence or the level of smoke, heat and / or carbon monoxide or a combination of these elements. The advantages, aims and particular characteristics of this housing and this detector being similar to those of the method as succinctly described above, they are not recalled here.
D'autres avantages, buts et caractéristiques de la présente invention ressortiront de la description qui va suivre, faite, dans un but explicatif et nullement limitatif en regard du dessin annexé dans lequel : la figure 1 représente, en élévation, un détecteur de fumée incorporant un mode de réalisation particulier du dispositif de sécurité objet de la présente invention, - la figure 2 représente, schématiquement et en coupe, une lame souple du socle illustré en figure 1 , en l'absence de pile, la figure 3 représente, schématiquement et en coupe, une lame souple du socle illustré en figure 1 au cours d'une étape de fixation de la pièce intermédiaire illustrée en figure 1 sur le socle illustré en figure 1 et la figure 4 représente, schématiquement et en coupe, la lame souple illustrée en figure 3 à la fin d'une étape de fixation de la pièce intermédiaire illustrée en figure 1 sur le socle illustré en figure 1.Other advantages, aims and features of the present invention will emerge from the description which follows, made for an explanatory and non-limiting purpose with reference to the appended drawing in which: FIG. 1 represents, in elevation, a smoke detector incorporating a particular embodiment of the safety device object of the present invention, FIG. 2 represents, schematically and in section, a flexible blade of the base illustrated in FIG. 1, in the absence of a battery, FIG. 3 is a diagrammatic sectional view of a flexible blade of the base illustrated in FIG. a step of fixing the intermediate piece illustrated in Figure 1 on the base shown in Figure 1 and Figure 4 shows schematically and in section, the flexible blade shown in Figure 3 at the end of a step of fixing the workpiece intermediate illustrated in Figure 1 on the base shown in Figure 1.
On observe, en figure 1 , un détecteur 100 comportant, à partir d'un support 105, par exemple un mur ou un plafond, un socle 110 et un boîtier 115. Le boîtier 115 comporte un couvercle 120 et une pièce intermédiaire 125 comportant un logement 130 pour une pile 135, un moyen de solidarisation 140 avec le couvercle 120 et un moyen de fixation 145 sur le socle 110. Le socle 110 comporte deux lames souples 150 et des moyens de solidarisation 160 avec le support 105. Le détecteur 100 comporte un capteur 165, de type connu, adapté à émettre un signal représentatif d'une grandeur physique, par exemple d'une présence de fumée et/ou de monoxyde de carbone dans l'air ambiant et/ou de la chaleur de l'air ambiant. Le détecteur 100 comporte aussi un circuit d'alarme 170, de type connu, adapté à traiter le signal issu du capteur 165 et à déclencher une alarme en fonction de critère prédéterminés, par exemple le franchissement d'une valeur seuil par ledit signal.FIG. 1 shows a detector 100 comprising, from a support 105, for example a wall or a ceiling, a base 110 and a housing 115. The housing 115 comprises a cover 120 and an intermediate piece 125 comprising a housing 130 for a battery 135, a securing means 140 with the cover 120 and a fixing means 145 on the base 110. The base 110 comprises two flexible blades 150 and securing means 160 with the support 105. The detector 100 comprises a sensor 165, of known type, adapted to emit a signal representative of a physical quantity, for example a presence of smoke and / or carbon monoxide in the ambient air and / or the heat of the air ambient. The detector 100 also comprises an alarm circuit 170, of known type, adapted to process the signal from the sensor 165 and to trigger an alarm according to predetermined criteria, for example the crossing of a threshold value by said signal.
Le socle 110 est, préférentiellement, une pièce en matière plastique moulée. Les moyens de solidarisation 160 du socle 110 sont, dans le mode de réalisation décrit et représenté, des ouvertures traversantes par lesquelles peuvent être vissées des vis de type connu. La forme du socle 110 est généralement circulaire et plane munie d'une rebord périphérique 111.The base 110 is, preferably, a molded plastic part. The securing means 160 of the base 110 are, in the embodiment described and shown, through openings through which screws of known type can be screwed. The shape of the base 110 is generally circular and flat provided with a peripheral rim 111.
Les lames souples 150 sont diamétralement opposées et présentent une forme de languette en « S » comportant trois parties sensiblement planes reliées entre elles par des parties courbes, comme illustré en figure 2. Plus précisément, dans le mode de réalisation décrit et représenté, les lames souples 150 présentent, en coupe, une partie de liaison renforcée 151 avec le reste du socle 110, se poursuivant par une partie élongée 152 sensiblement parallèle à la surface du socle 110, se poursuivant par une partie oblique 153 s'éloignant progressivement du socle, par exemple formant, avec la surface du socle 110, un angle compris entre 15 et 45 degrés et s'achève par une partie plane 154, incurvée vers le socle 110, par rapport à la partie oblique 153 et sensiblement plane. En regard des lames souples 150, le socle 110 présente des évidements ou des ouvertures traversantes permettant aux lames souples 150 de se courber vers le socle 110 lors de la fermeture du détecteur 100, en présence d'une pile 135 dans le logement de pile 130 (voir figure 3).The flexible blades 150 are diametrically opposed and have an "S" -shaped shape comprising three substantially flat portions interconnected by curved parts, as illustrated in FIG. 2. More precisely, in the embodiment described and shown, the blades flexible 150 have, in section, a reinforced connection portion 151 with the rest of the base 110, continuing with an elongated portion 152 substantially parallel to the surface of the base 110, continuing with an oblique portion 153 away from the base, for example forming, with the surface of the base 110, an angle of between 15 and 45 degrees and ends with a flat portion 154, curved towards the base 110, with respect to the oblique portion 153 and substantially flat. Opposite the flexible blades 150, the base 110 has recesses or through openings allowing the flexible blades 150 to bend towards the base 110 when the detector 100 is closed, in the presence of a battery 135 in the battery compartment 130 (see FIG. 3).
Le socle 110 comporte aussi, sur son rebord périphérique deux lamelles latérales 180 diamétralement opposées, pour la fixation de la pièce intermédiaire 125 sur le socle 110. La pièce intermédiaire 125, de son côté en regard avec le socle 110, présente une forme généralement circulaire et plane avec un rebord périphérique 155 et un logement 175 pour chaque lamelle 180. Le logement 130 pour une pile 135 présente une profondeur sensiblement égale à celle de la pile d'alimentation du détecteur 100. Il s'agit, dans le mode réalisation décrit et représenté, d'une pile 9V de forme parallélépipédique rectangulaire. Le moyen de solidarisation 140 avec le couvercle 120 est de type connu, par exemple constitué de vis.The base 110 also has, on its peripheral rim, two diametrically opposite side lamellae 180 for fastening the intermediate piece 125 to the base 110. The intermediate piece 125, on its side facing the base 110, has a generally circular shape. and plane with a peripheral rim 155 and a housing 175 for each lamella 180. The housing 130 for a battery 135 has a depth substantially equal to that of the detector's power supply cell 100. In the embodiment described and shown, a 9V rectangular parallelepiped shaped stack. The securing means 140 with the cover 120 is of known type, for example consisting of screws.
Le moyen de fixation 145 de la pièce intermédiaire 125 et du couvercle 120 sur le socle 110 est constitué de deux lamelles latérales 185 adaptées à s'enclencher, dans les lamelles latérales 180 du socle 110, lors d'un mouvement de rotation dans le sens des aiguilles d'une montre, de la pièce intermédiaire 125 sur le socle 110.The fixing means 145 of the intermediate piece 125 and the cover 120 on the base 110 consists of two lateral strips 185 adapted to snap into the side lamellas 180 of the base 110, during a rotational movement in the direction clockwise, the intermediate piece 125 on the base 110.
Comme illustré en figure 2, en l'absence de pile dans le logement de pile, au cours de la tentative de fermeture du boîtier, lors du passage du logement de pile en regard de la lame souple, celle-ci prend sa position au repos. Une paroi arrière du logement de pile vient alors buter contre l'extrémité saillante de la lame souple et la fermeture du boîtier ne peut être effectuée.As illustrated in FIG. 2, in the absence of a battery in the battery compartment, during the attempt to close the casing, during the passage of the battery housing opposite the flexible blade, the latter takes its rest position. . A rear wall of the battery housing then abuts against the projecting end of the flexible blade and closing the housing can not be performed.
Au contraire, comme illustré en figure 3, lorsque la pile est présente dans son logement, au cours de la tentative de fermeture du boîtier, la pile contraint la lame souple à rester inclinée vers le support et empêche la lame souple de faire saillie. La rotation de la partie intermédiaire est ainsi libre et la lame souple ne peut reprendre sa position au repos que lorsque le boîtier est fermé, comme illustré en figure 4.On the contrary, as illustrated in Figure 3, when the battery is present in its housing, during the attempt to close the housing, the stack forces the flexible blade to remain inclined towards the support and prevents the flexible blade to protrude. The rotation of the intermediate portion is thus free and the flexible blade can resume its rest position only when the housing is closed, as shown in Figure 4.
On observe, en regard des figures 2 à 4 que, préférentiellement, la pièce intermédiaire possède un espace libre dans lequel la lame souple peut se détendre et reprendre sa position de repos. Ceci présente au moins deux avantages. D'une part, la lame souple ne reste pas contrainte longtemps (seulement lors des phases d'ouverture ou de fermeture du boîtier), ce qui limite le risque de fatigue et donc de perte d'élasticité de la lame souple. D'autre part, la lame souple détendue dans l'espace libre retient la pièce intermédiaire en position de fermeture du boîtier, réduisant ainsi les risques d'ouverture involontaire.It is observed, with reference to FIGS. 2 to 4, that, preferably, the intermediate piece has a free space in which the flexible blade can relax and return to its rest position. This has at least two advantages. On the one hand, the flexible blade does not remain constrained long (only during the opening or closing phases of the housing), which limits the risk of fatigue and therefore loss of elasticity of the flexible blade. On the other hand, the flexible blade relaxed in the free space holds the intermediate piece in the closed position of the housing, thus reducing the risk of unintentional opening.
A la lecture de ce qui précède, on comprend que le dispositif de sécurisation de boîtier décrit et représenté comporte un socle muni d'au moins une lame souple mobile entre une position au repos dans laquelle la lame souple dépasse d'une surface dudit socle et une position contrainte dans laquelle la lame souple ne dépasse pas de ladite surface et une pièce intermédiaire comportant un logement de pile et un moyen de fixation de ladite pièce sur ledit socle, ledit moyen de fixation imposant le passage dudit logement en regard de ladite lame souple. Lorsque la pile est absente, lors d'une tentative de fixation de la pièce intermédiaire sur le socle, le logement de pile passe en regard de ladite lame qui, du fait de l'absence de la pile peut prendre sa position au repos et bloquer le mouvement de fixation. Au contraire, lorsque la pile est présente, la lame souple ne peut pas prendre sa position au repose et ne bloque donc pas le mouvement de fixation.On reading the foregoing, it is understood that the housing protection device described and shown comprises a base provided with at least one flexible blade movable between a rest position in which the flexible blade protrudes from a surface of said base and a constrained position in which the flexible blade does not protrude from said surface and a intermediate piece comprising a battery housing and a means for fixing said part on said base, said fixing means imposing the passage of said housing opposite said flexible blade. When the battery is absent, during an attempt to fix the intermediate piece on the base, the battery compartment passes next to said blade which, because of the absence of the battery can take its position at rest and block the fixing movement. On the contrary, when the battery is present, the flexible blade can not take its position at rest and thus does not block the fixing movement.
La présente invention ne se limite pas au mode de réalisation particulier décrit et représenté. Au contraire, elle s'étend à toute variante à la portée de l'homme du métier. En particulier, la lame souple peut être placée sur la pièce intermédiaire et le logement de pile sur le socle. De même, une lame soupe peut être placée latéralement sur le rebord périphérique du socle ou de la pièce intermédiaire. The present invention is not limited to the particular embodiment described and shown. On the contrary, it extends to any variant within the reach of the skilled person. In particular, the flexible blade can be placed on the intermediate piece and the battery housing on the base. Similarly, a soup blade may be placed laterally on the peripheral rim of the base or the intermediate piece.
