Description

DOMAINE TECHNIQUE ET ART ANTÉRIEURTECHNICAL FIELD AND PRIOR ART

La présente invention se rapporte à un dispositif de détection de la position de deux éléments mobiles l'un par rapport à l'autre dont l'intégration est améliorée, notamment à un capteur destiné à être mis en oeuvre dans des dispositifs d'assistance ou de surveillance, type alarme.The present invention relates to a device for detecting the position of two movable elements relative to each other whose integration is improved, in particular to a sensor intended to be implemented in assistance devices or monitoring, alarm type.

Les dispositifs de détection ou capteur d'une position relative de deux éléments de type connu sont interposés entre les deux éléments et captent une modification des paramètres de l'environnement, du fait par exemple d'un déplacement d'une pièce mobile dans le capteur. Dans le cas d'un réfrigérateur, l'ouverture de la porte provoque l'illumination de l'ampoule qui est disposée à l'intérieur du réfrigérateur. Dans ce cas, le capteur est formé d'un téton maintenu en contact avec la porte par un ressort. Le déplacement de ce téton provoque, lorsque la porte est fermée, l'ouverture du circuit électrique d'alimentation de l'ampoule. Lors de l'ouverture de la porte, le téton se déplace en position inverse, provoquant la fermeture du circuit électrique et l'alimentation en électricité de l'ampoule et son illumination. Le circuit électrique est rapporté sur la structure du réfrigérateur.The detection devices or sensor of a relative position of two elements of known type are interposed between the two elements and capture a modification of the parameters of the environment, for example because of a displacement of a moving part in the sensor . In the case of a refrigerator, the opening of the door causes the illumination of the bulb which is disposed inside the refrigerator. In this case, the sensor is formed of a pin held in contact with the door by a spring. The displacement of this pin causes, when the door is closed, the opening of the electrical supply circuit of the bulb. When opening the door, the nipple moves in the opposite position, causing the closure of the electrical circuit and the power supply of the bulb and its illumination. The electrical circuit is attached to the refrigerator structure.

Le document EP 1 014 322 B1 décrit un dispositif d'effraction d'un volet roulant obturant une ouverture. Ce dispositif comporte un capteur sur la lame inférieure du volet pour informer de la position de la lame inférieure relativement au cadre inférieur du volet. Ce capteur est formé par un téton en saillie de la lame inférieure. Celui-ci, lorsque le volet roulant est fermé, est en contact avec le cadre inférieur de l'ouverture. Le téton occupe alors une position enfoncée, et aucune information n'est envoyée par onde radio à un récepteur radio.The document EP 1 014 322 B1 discloses a device for breaking a rolling shutter closing an opening. This device comprises a sensor on the lower blade of the flap to inform of the position of the lower blade relative to the lower frame of the flap. This sensor is formed by a protruding nipple of the lower blade. When the shutter is closed, it is in contact with the lower frame of the opening. The pin then occupies a depressed position, and no information is sent by radio wave to a radio receiver.

En cas d'effraction, c'est-à-dire lorsque le volet roulant est soulevé, la lame inférieure est alors écartée du bord inférieur de l'ouverture, et le téton n'occupe plus de position enfoncée. Ce changement de position du téton provoque l'envoi d'un signal radio par un émetteur au récepteur radio, et par exemple l'activation d'une alarme. L'émetteur est rapporté sur le volet roulant.In case of break-in, that is to say when the shutter is raised, the lower blade is then spaced from the lower edge of the opening, and the pin no longer occupies a depressed position. This change of position of the pin causes the sending of a radio signal by a transmitter to the radio receiver, and for example the activation of an alarm. The transmitter is attached to the shutter.

Ces dispositifs de détection présentent l'inconvénient de nécessiter d'être rapportés sur l'un au moins des éléments dont on veut détecter un déplacement relatif, ou à proximité de ceux-ci. Cet ajout peut être parfois complexe, inesthétique et augmenter le coût de revient de la structure.These detection devices have the disadvantage of requiring to be reported on at least one of the elements which we want to detect a relative movement, or in proximity thereof. This addition can sometimes be complex, unsightly and increase the cost of the structure.

C'est par conséquent un but de la présente invention d'offrir un dispositif de détection intégré au système qu'il équipe, sans en perturber le fonctionnement, ni en détériorer de manière substantielle l'apparence.It is therefore an object of the present invention to provide a detection device integrated into the system. that it equips, without disturbing its operation, nor substantially deteriorating the appearance.

Le but précédemment énoncé est atteint par un dispositif de détection de la position relative de deux éléments, l'un des deux éléments remplissant une fonction mécanique à part entière, le dispositif comportant au moins l'un des éléments.The previously stated purpose is achieved by a device for detecting the relative position of two elements, one of the two elements fulfilling a mechanical function in itself, the device comprising at least one of the elements.

En d'autres termes, on utilise au moins l'un des éléments dont on veut capter la position relativement à l'autre élément pour transmettre l'information du rapprochement ou de l'éloignement des deux éléments, alors que cet élément remplit sa fonction mécanique.In other words, we use at least one of the elements whose position we want to capture relative to the other element to transmit the information of the approximation or the removal of the two elements, while this element fulfills its function mechanical.

Pour cela, le capteur selon la présente invention comporte un circuit électrique apte à être ouvert et fermé suivant la position des deux éléments, l'un au moins des éléments étant un conducteur électrique formant une partie d'un circuit électrique, le rapprochement ou l'éloignement de l'autre élément provoquant la fermeture ou l'ouverture d'un circuit électrique.For this, the sensor according to the present invention comprises an electric circuit able to be opened and closed according to the position of the two elements, at least one of the elements being an electrical conductor forming part of an electrical circuit, the approximation or the distance from the other element causing the closing or opening of an electrical circuit.

La présente invention présente l'avantage d'offrir un dispositif de détection très robuste, puisqu'il n'est pas rapporté sur le dispositif équipé, mais intégré au moins en partie à l'un des éléments dont on veut détecter la position relative.The present invention has the advantage of providing a very robust detection device, since it is not reported on the device equipped, but integrated at least in part to one of the elements whose relative position is to be detected.

La présente invention, par conséquent, a principalement pour objet un dispositif de détection d'une position relative d'un premier élément, ayant une fonction mécanique principale, et d'un deuxième élément, comportant un circuit électrique dont l'ouverture et la fermeture correspondent respectivement à une première et une deuxième position des premier et deuxième éléments l'un par rapport à l'autre, dans lequel au moins le premier élément forme une partie du circuit électrique.The present invention, therefore, mainly relates to a device for detecting a relative position of a first element, having a main mechanical function, and a second element, comprising an electrical circuit whose opening and closing correspond respectively to a first and a second position of the first and second elements relative to each other, wherein at least the first element forms part of the electrical circuit.

Dans la présente demande, on entend par «élément ayant une première fonction mécanique principale », un élément qui remplit une fonction mécanique quelconque. Celle-ci peut être, par exemple une fonction de support dans le cas d'un cadre de porte, de préhension, dans le cas notamment d'une poignée de porte, de suspension ou d'accrochage, dans le cas par exemple d'un moyen d'accrochage d'objet. La liste énoncée ci-dessus n'est pas exhaustive, elle peut concerner également un élément de support, telle qu'une console, des tasseaux, etc.In the present application, the term "element having a first main mechanical function", an element that performs any mechanical function. This may be, for example a support function in the case of a door frame, gripping, in the case in particular of a door handle, suspension or hooking, in the case for example of an object hooking means. The list stated above is not exhaustive, it may also relate to a support element, such as a console, cleats, etc.

On entend également, dans la présente demande, par première position et deuxième position, une disposition relative et une autre disposition relative, chacune de ces dispositions relatives n'étant pas nécessairement unique. Par exemple, dans le cas d'une porte, la première position peut correspondre à la position complètement fermée, dans laquelle le battant est aligné avec le chambranle et la deuxième position correspond à la position ouverte, cette position ouverte comportant toutes les positions du battant de porte par rapport au chambranle de la porte, de faiblement ouverte à grande ouverte. Ainsi la deuxième position comporte en réalité une multitude de positions du battant par rapport au chambranle.In the present application, the first and second positions also include a relative provision and another relative provision, each of which is not necessarily unique. For example, in the case of a door, the first position may correspond to the fully closed position, in which the door is aligned with the door frame and the second position corresponds to the open position, this open position comprising all the positions of the door leaf relative to the door jamb, from slightly open to wide open. Thus the second position in fact comprises a multitude of positions of the wing relative to the doorframe.

On pourrait également prévoir que la position fermée pour une porte corresponde à un seuil de fermeture minimale, par exemple dans le cas de volet roulant. On pourrait considérer que le volet roulant est en position fermée, lorsqu'il obture l'ouverture au 3/4 ou 4/5ème.It could also be provided that the closed position for a door corresponds to a minimum closing threshold, for example in the case of shutters. It could be considered that the shutter is in the closed position, when it closes the opening to 3/4 or 4/5 th .

Ainsi, le premier élément, en plus de remplir sa fonction mécanique première, remplir la fonction supplémentaire, de transmetteur d'information à un dispositif de détection de la position relative de ce premier élément par rapport au deuxième élément. Ce deuxième élément peut remplir une fonction mécanique identique à celle du premier élément, par exemple dans le cas d'une poignée formée par un premier élément et un deuxième élément. Le deuxième élément peut également remplir une fonction complémentaire à celle du premier élément, par exemple dans le cas où le premier élément est un encadrement d'une porte et le deuxième élément et un battant de la porte.Thus, the first element, in addition to fulfilling its primary mechanical function, fulfills the additional function of transmitting information to a device for detecting the relative position of this first element relative to the second element. This second element can fulfill a mechanical function identical to that of the first element, for example in the case of a handle formed by a first element and a second element. The second element may also perform a function complementary to that of the first element, for example in the case where the first element is a frame of a door and the second element and a door leaf.

Selon l'invention, le premier élément peut comporter deux parties conductrices électriquement isolées.According to the invention, the first element may comprise two electrically insulated conductive parts.

Le dispositif selon l'invention peut servir à la détection d'une ouverture ou d'une fermeture d'une porte ou d'une fenêtre. Le premier élément peut alors être un chambranle de porte ou de fenêtre, et le deuxième élément peut être un ouvrant de porte ou de fenêtre respectivement.The device according to the invention can be used for detecting an opening or closing of a door or a window. The first element can then be a door or window jamb, and the second element can be a door or window opening respectively.

De manière avantageuse, le chambranle de porte peut comporter un cadre extérieur électriquement conducteur et un cadre intérieur électriquement conducteur, lesdits cadres extérieur et intérieur formant lesdits conducteurs électriques, au moins l'un des cadres comportant une discontinuité électrique apte à être comblée par une pièce électriquement conductrice mobile pour fermer le circuit électrique, ladite pièce mobile étant soit portée par l'ouvrant, soit disposée dans la discontinuité et mettant en contact des parties de part et d'autre de la discontinuité lors du rapprochement ou de l'éloignement de l'ouvrant.Advantageously, the door frame may comprise an electrically conductive outer frame and an electrically conductive inner frame, said outer and inner frames forming said electrical conductors, at least one of the frames having an electrical discontinuity capable of being filled by a part mobile electrically conductive to close the electrical circuit, said movable piece being either carried by the opening, or disposed in the discontinuity and bringing into contact parts on either side of the discontinuity during the approximation or removal of the 'opening.

La pièce mobile, électriquement conductrice, est par exemple en forme de T, les bras du T étant destinés à venir chacun en contact avec des parties de part et d'autre de la discontinuité et le pied du T servant de moyen d'actionnement destiné à venir en contact avec l'ouvrant, la fermeture de la porte provoquant un éloignement des branches du T des parties de part et d'autre de la discontinuité.The moving part, electrically conductive, is for example T-shaped, the arms of the T being intended to come into contact with parts on either side of the discontinuity and the foot of the T serving as an actuating means for to come into contact with the opening, closing the door causing a distance of the branches of the T parts on either side of the discontinuity.

La pièce mobile électriquement conductrice peut également être formée par une gâche mobile apte à être déplacée par un pêne.The electrically conductive moving part may also be formed by a movable striker adapted to be moved by a bolt.

Il peut également être prévu des moyens d'illumination type diode, aptes à être éclairés lorsque le circuit électrique est fermé, montés entre le cadre intérieur et le cadre extérieur.It can also be provided diode-type illumination means, capable of being illuminated when the electrical circuit is closed, mounted between the inner frame and the outer frame.

La présente invention a également pour objet une installation de surveillance, comportant plusieurs dispositifs de détection selon la présente invention, reliés électriquement en série.The present invention also relates to a surveillance installation, comprising several detection devices according to the present invention, electrically connected in series.

Les premiers éléments de chaque dispositif peuvent alors être reliés électriquement par des plinthes.The first elements of each device can then be electrically connected by baseboards.

La présente invention a également pour objet un dispositif de détection de la présence ou de l'absence d'un objet, le premier élément formant un support d'accrochage pour un bras de suspension dudit objet.The present invention also relates to a device for detecting the presence or absence of an object, the first element forming a hooking support for a suspension arm of said object.

Les deux conducteurs électriques sont alors aptes à être connectés électriquement pour fermer le circuit électrique par le deuxième élément formé par un plongeur électriquement conducteur déplaçable par application d'une charge sur le bras de suspension.The two electrical conductors are then able to be electrically connected to close the electrical circuit by the second element formed by an electrically conductive plunger displaceable by applying a load on the suspension arm.

La charge est, par exemple transmise par le bras de suspension au plongeur.The load is, for example transmitted by the suspension arm to the plunger.

Les deux conducteurs électriques peuvent être formés par des profilés ou des câbles aptes à permettre la suspension et la surveillance de plusieurs objets.The two electrical conductors may be formed by profiles or cables capable of allowing the suspension and monitoring of several objects.

Dans le cas où les conducteurs électriques sont formés par des profilés, un premier profilé comporte un tube à section rectangulaire muni sur une face d'une rainure, un deuxième profilé comporte un tube à section rectangulaire muni sur une face d'une rainure, les deux rainures étant disposées en regard, un matériau électriquement isolant étant disposé entre les deux faces des tubes comportant les rainures, le deuxième tube comportant sur une face opposée à la face comportant la rainure des orifices pour le passage d'un doigt de transmission de la charge, le palpeur étant monté mobile perpendiculairement à l'axe du tube, une base du plongeur étant montée dans le tube du premier élément, un palpeur du plongeur étant monté dans le tube du deuxième élément, ledit palpeur étant en regard d'un passage du doigt, le palpeur étant rappelé élastiquement vers le passage du doigt.In the case where the electrical conductors are formed by profiles, a first profile comprises a rectangular section tube provided on one side with a groove, a second profile comprises a rectangular section tube provided on one side with a groove, the two grooves being disposed facing each other, an electrically insulating material being disposed between the two faces of the tubes comprising the grooves, the second tube having on a face opposite to the face having the groove orifices for the passage of a transmission pin of the charge, the probe being mounted movable perpendicularly to the axis of the tube, a base of the plunger being mounted in the tube of the first element, a probe of the plunger being mounted in the tube of the second element, said probe being opposite a passage finger, the probe being elastically returned to the passage of the finger.

La présente invention a également pour objet une installation de surveillance, dans lequel le premier élément du dispositif selon la présente invention forme une corniche courant le long d'au moins une partie d'un mur permettant la fixation et de plusieurs objets l'un à côté des autres et leur surveillance.Another subject of the present invention is a surveillance installation, in which the first element of the device according to the present invention forms a cornice running along at least a part of a wall allowing the attachment and of several objects, one to next to others and their supervision.

Le premier et le deuxième élément sont, par exemple deux parties d'une poignée d'ouverture d'un ouvrant, lesdites parties étant réalisées en matériaux électriquement conducteurs, l'actionnement de la poignée provoquant la mise en contact électrique des premier et deuxième éléments et l'activation d'un moyen d'assistance à l'ouverture.The first and second elements are, for example two parts of an opening handle of an opening, said portions being made of electrically conductive materials, the actuation of the handle causing the first and second elements to come into electrical contact and the activation of an opening assistance means.

Les deux éléments de la poignée comportent avantageusement une partie allongée avec une saillie en partie médiane, les deux saillies étant en regard et destinées à venir en contact, des moyens élastiques maintenant les deux saillies éloignées l'un de l'autre au repos.The two elements of the handle advantageously comprise an elongate portion with a projection in the middle part, the two projections being opposite and intended to come into contact, elastic means keeping the two projections distant from each other at rest.

Le moyen d'assistance peut être du type moteur électrique.The assistance means may be of the electric motor type.

EXPOSÉ DÉTAILLÉ DE MODES DE RÉALISATION PARTICULIERSDETAILED PRESENTATION OF PARTICULAR EMBODIMENTS

Sur la figure 1, on peut voir un premier exemple de réalisation d'un dispositif de détection selon la présente invention destiné à permettre la détection de l'ouverture et de la fermeture d'une porte 2.FIG. 1 shows a first embodiment of a detection device according to the present invention for detecting the opening and closing of a door 2.

Selon la présente invention, le dispositif de détection comporte un circuit électrique 4 apte à être fermé par fermeture de la porte 2 et ouvert par ouverture de la porte 2, l'ouverture et la fermeture du circuit étant traitées par une unité 5 de traitement d'information qui, en fonction du passage ou non du courant, émet un signal d'information relatif à la fermeture ou à l'ouverture de la porte.According to the present invention, the detection device comprises an electric circuit 4 adapted to be closed by closing the door 2 and opened by opening the door 2, the opening and closing of the circuit being processed by a treatment unit 5. information which, depending on the passage or not of the current, emits an information signal relating to the closing or opening of the door.

La porte 2 comporte un chambranle 6 délimitant une ouverture 8 et un battant 10 destiné à venir s'appliquer contre le chambranle 6 pour obturer l'ouverture 8.The door 2 has a doorframe 6 defining an opening 8 and a door 10 intended to be pressed against the doorframe 6 to close the opening 8.

Selon la présente invention, le chambranle 6 comporte un cadre extérieur 12 en matériau conducteur, un cadre intérieur 14 également en matériau conducteur, le premier 12 et le deuxième 14 cadre sont raccordés électriquement et reliés à une source de courant électrique 16, formant le circuit électrique 4.According to the present invention, the frame 6 comprises an outer frame 12 made of conductive material, an inner frame 14 also made of conductive material, the first 12 and the second 14 frame are electrically connected and connected to a source of electric current 16, forming the electric circuit 4.

Le cadre intérieur 14 comporte une discontinuité électrique. Dans l'exemple représenté, celui-ci comporte une première partie 14.1 et une deuxième partie 14.2 séparées par un espace 15 rempli soit par de l'air, soit par un matériau solide électriquement isolant.The inner frame 14 has an electrical discontinuity. In the example shown, it comprises a first portion 14.1 and a second portion 14.2 separated by a space 15 filled either with air or with an electrically insulating solid material.

Le battant 10 est monté pivotant dans l'exemple représenté sur la chambranle 6, mais il pourrait également être monté coulissant dans celui-ci.The leaf 10 is pivotally mounted in the example shown on the frame 6, but it could also be slidably mounted therein.

Le battant 10 comporte au moins un élément 18 en matériau conducteur électrique disposé de telle sorte qu'il mette en contact électrique les première 14.1 et deuxième 14.2 parties du cadre intérieur 14, lorsque le battant 10 est appliqué contre le chambranle 6.The leaf 10 comprises at least one element 18 made of electrically conductive material disposed in such a way that it makes the first 14.1 and second 14.2 parts of the inner frame 14 come into electrical contact when the leaf 10 is applied against the frame 6.

Sur la figure 2A, on peut voir le cadre extérieur 12 et le cadre intérieur 14 formés par des profilés. Dans l'exemple représenté, le cadre extérieur 12 a une section transversale en forme d'équerre et le cadre intérieur a une section transversale rectangulaire. Un matériau électriquement isolant 17 est interposé entre le cadre extérieur 12 et le cadre intérieur 14.In Figure 2A, we can see the outer frame 12 and the inner frame 14 formed by profiles. In the example shown, the outer frame 12 has a square cross section and the inner frame has a rectangular cross section. An electrically insulating material 17 is interposed between the outer frame 12 and the inner frame 14.

Dans l'exemple représenté, l'élément 18 est formé par une plaque montée sur la face du battant 10 destinée à venir en contact avec le chambranle 6.In the example shown, the element 18 is formed by a plate mounted on the face of the wing 10 intended to come into contact with the doorframe 6.

Sur la figure 2B, on peut voir la plaque 18 reliant électriquement les première 14.1 et deuxième 14.2 parties du cadre intérieur 14. Dans cette configuration, le courant circule dans le circuit 4 et l'unité de traitement détecte la fermeture de la porte 2.In FIG. 2B, one can see the plate 18 electrically connecting the first 14.1 and second 14.2 parts of the inner frame 14. In this configuration, the current flows in the circuit 4 and the processing unit detects the closing of the door 2.

Dans la configuration de la figure 1, la plaque 18 ne relie pas électriquement les première 14.1 et deuxième 14.2 parties du cadre intérieur 14, le courant ne circule pas dans le circuit électrique 4, l'unité de traitement détecte alors la position ouverte de la porte 2.In the configuration of Figure 1, the plate 18 does not electrically connect the first 14.1 and second 14.2 parts of the inner frame 14, the current does not flow in the electrical circuit 4, the processing unit then detects the open position of the door 2.

La présente invention s'applique également à des fenêtres. Dans le cas de fenêtres à plusieurs battants, notamment à deux battants, il est prévu de pouvoir détecter l'ouverture de l'un et/ou de l'autre des battants. Dans l'exemple représenté, l'élément porté par chacun des battants, et apte à ouvrir le circuit électrique lorsque le battant est fermé, est disposé sur le côté de la fenêtre portant les gonds. Cet élément peut aussi être disposé sur l'une des autres parties de l'encadrement de la fenêtre.The present invention also applies to windows. In the case of multi-leaf windows, in particular with two leaves, it is planned to be able to detect the opening of one and / or the other of the leaves. In the example shown, the element carried by each of the leaves, and adapted to open the electrical circuit when the leaf is closed, is disposed on the side of the window carrying the hinges. This element can also be arranged on one of the other parts of the frame of the window.

On peut ainsi réaliser une surveillance de toutes ou partie des ouvertures d'une habitation, tel que cela est schématiquement représenté sur la figure 6, sur lequel les cadres intérieur 14 et extérieur 12 d'une porte P, les cadres intérieur 28 et extérieur 30 d'une première fenêtres F1, les cadres intérieur 32 et extérieur 34 d'une deuxième fenêtre F2 sont reliées électriquement en série par des plinthes conductrices 36, 38 formant le prolongement de chacun des cadres intérieur 14, 28, 32 et extérieur 12, 30, 34. Dans cette configuration, un seul battant ouvert ferme le circuit électrique reliant toutes les ouvertures de l'habitation et provoque, par exemple l'émission d'un signal d'alarme. La configuration inverse, dans laquelle l'ouverture d'un battant provoquerait l'ouverture du circuit est également envisageable, de manière comparable au dispositif de la figure 1.It is thus possible to monitor all or part of the openings of a dwelling, such as that is schematically shown in Figure 6, in which the inner frames 14 and outer 12 of a door P, the inner frames 28 and outer 30 of a first F1 windows, the inner 32 and outer 34 frames of a second window F2 are electrically connected in series by conductive skirting 36, 38 forming the extension of each of the inner frames 14, 28, 32 and outer 12, 30, 34. In this configuration, a single open flap closes the electrical circuit connecting all the openings of housing and causes, for example the emission of an alarm signal. The opposite configuration, in which the opening of a leaf would cause the opening of the circuit is also possible, comparable to the device of Figure 1.

Les éléments électriquement conducteurs peuvent être, par exemple réalisés en matériau conducteur massif ou comporter une âme ou une couche de matériau conducteur.The electrically conductive elements may be, for example made of solid conductive material or comprise a core or a layer of conductive material.

Sur la figure 3, on peut voir un autre exemple de porte, dans laquelle la plaque 18 est placée sur une tranche 20 du battant 10 ; dans ce cas le cadre intérieur 14 est disposé perpendiculairement aux faces du battant 10.In Figure 3, we can see another example of a door, in which the plate 18 is placed on a wafer 20 of the wing 10; in this case the inner frame 14 is arranged perpendicularly to the faces of the leaf 10.

On peut également envisager d'utiliser un pêne de la porte pour fermer le circuit électrique 4.One can also consider using a bolt of the door to close the electrical circuit 4.

On peut envisager d'ouvrir le circuit électrique 4 lorsqu'on ferme la porte, au lieu de le fermer. Dans ce cas, on peut prévoir une gâche avec une partie mobile, cette partie mobile fermant le circuit électrique lorsque la porte est ouverte, et ouvrant le circuit lors de la fermeture de la porte, par pression du pêne sur la partie mobile de la gâche.One can consider opening the electrical circuit 4 when closing the door, instead of closing it. In this case, one can provide a strike with a movable part, this moving part closing the electrical circuit when the door is open, and opening the circuit during closing of the door, by pressing the bolt on the movable part of the striker.

Dans les exemples de réalisation décrits, la fermeture du circuit électrique s'effectue sensiblement au niveau d'une poignée de porte (non représentée), mais la plaque 18, ainsi que la discontinuité du cadre intérieur 14 peuvent être prévues à un emplacement différent, par exemple sur une partie supérieure de la porte ou du côté des gonds, de manière à améliorer d'avantage l'esthétique de la porte.In the embodiments described, the closure of the electrical circuit is substantially at the level of a door handle (not shown), but the plate 18, as well as the discontinuity of the inner frame 14 may be provided at a different location, for example on an upper part of the door or the side of the hinges, so as to further improve the aesthetics of the door.

Sur les figures 4A et 4B, on peut voir un autre exemple de réalisation d'un dispositif de détection appliqué à une porte, dans ce cas l'ouverture ou la fermeture du circuit électrique est obtenue par une pièce conductrice mobile dans le chambranle, dont le déplacement est commandé par le battant de porte.FIGS. 4A and 4B show another embodiment of a detection device applied to a door, in which case the opening or closing of the electrical circuit is obtained by a movable conductive part in the doorframe, of which the movement is controlled by the door leaf.

Les mêmes références que celles utilisées pour les figures 1 à 3 seront utilisées pour la description des figures 4A et 4B.The same references as those used for FIGS. 1 to 3 will be used for the description of FIGS. 4A and 4B.

Dans l'exemple représenté, c'est le cadre extérieur 12 qui est discontinu et comporte une première 12.1 et deuxième 12.2 parties séparées par un espace 15 non conducteur électrique; les parties 12.1 et 12.2 sont destinées à être mises en contact électrique par comblement de l'espace 15 ou franchissement par un conducteur électrique de l'espace 15.In the example shown, it is the outer frame 12 which is discontinuous and has a first 12.1 and second 12.2 parts separated by a space 15 non-electrically conductive; parts 12.1 and 12.2 are intended to be brought into electrical contact by filling of the space 15 or crossing by an electrical conductor of the space 15.

Une pièce conductrice 22 est montée mobile dans l'espace 15. Elle peut être par exemple en forme de T, les deux branches du T 22.1, 22.2 venant en contact respectivement avec les parties 12.1, 12.2 et permettant le passage du courant.A conductive part 22 is movably mounted in the space 15. It may be for example T-shaped, the two branches of the T 22.1, 22.2 coming into contact respectively with the parts 12.1, 12.2 and allowing the passage of the current.

Le pied 22.3 du T 22 est monté dans l'espace 15 et est destiné à venir en contact avec le battant 10. Le T 22 est rappelé élastiquement vers l'extérieur du cadre extérieur 12, en direction du battant 10.The foot 22.3 of the T 22 is mounted in the space 15 and is intended to come into contact with the leaf 10. The T 22 is elastically urged towards the outside of the outer frame 12, in the direction of the leaf 10.

Ainsi, lorsque la porte est ouverte (figure 4B), les branches du T reliant électriquement les première 22.1 et deuxième 22.2 parties du cadre extérieur 12, provoquant le passage du courant dans le circuit, l'unité de traitement détecte l'ouverture de la porte.Thus, when the door is open (FIG. 4B), the branches of the T electrically connecting the first 22.1 and second 22.2 parts of the outer frame 12, causing the passage of the current in the circuit, the processing unit detects the opening of the door.

Lorsque la porte est fermée (figure 4A), le battant 10 est en appui sur le pied 22.3 du T 22 et éloigne les branches 22.1, 22.2 des première 12.1 et deuxième 12.2 parties du cadre intérieur 12 respectivement, ce qui ouvre le circuit électrique 4. L'unité de traitement détecte alors la fermeture de la porte.When the door is closed (FIG. 4A), the leaf 10 bears against the foot 22.3 of the T 22 and moves the branches 22.1, 22.2 away from the first 12.1 and second 12.2 parts of the inner frame 12 respectively, which opens the electrical circuit 4 The processing unit then detects the closing of the door.

Contrairement aux exemples de réalisation des figures 1 à 3, le courant circule dans le circuit électrique lorsque la porte est ouverte.Unlike the embodiments of Figures 1 to 3, the current flows in the electrical circuit when the door is open.

Le dispositif de détection peut permettre, par exemple d'activer un éclairage à l'intérieur de la pièce ou de l'espace fermé par la porte.The detection device may allow, for example to activate a lighting inside the room or space closed by the door.

Sur la figure 5, on peut voir des ampoules 24, type LED câblées en parallèle sur le cadre intérieur 14 et le cadre extérieur 12, telles que représentées sur la figure 5.In FIG. 5, light bulbs 24, LED type wired in parallel can be seen on the inner frame 14 and the outer frame 12, as shown in FIG.

Ainsi, lorsque le courant circule dans le circuit électrique 4, les diodes 24 s'éclairent.Thus, when the current flows in the electrical circuit 4, the diodes 24 light up.

Par conséquent, lorsque la porte est ouverte dans l'exemple de la figure 4B, les diodes illuminent l'intérieur de l'espace.Therefore, when the door is opened in the example of Figure 4B, the diodes illuminate the interior of the space.

Le dispositif de détection selon la présente invention peut donc être intégré à un meuble en matériau électriquement conducteur, par exemple en aluminium pour éclairer l'intérieur du meuble, lorsqu'un utilisateur ouvre la porte. En ouvrant le battant, la pression sur la pièce mobile 22 est relâchée, ce qui permet alors au courant de circuler dans les cadres intérieur 14 et extérieur 12 et dans les diodes.The detection device according to the present invention can be integrated into a piece of furniture made of electrically conductive material, for example aluminum to illuminate the interior of the furniture, when a user opens the door. By opening the leaf, the pressure on the moving part 22 is released, which then allows the current to flow in the inner 14 and outer 12 frames and in the diodes.

Dans le cas d'un chambranle réalisé selon la figure 5, celui-ci peut permettre de signaler une issue de secours.In the case of a doorframe made according to Figure 5, it may allow to report an emergency exit.

On peut prévoir d'avoir une installation de surveillance d'une habitation comportant plusieurs dispositifs selon la présente invention, dans laquelle les dispositifs de détection peuvent être tous identiques ou être de structures différentes, par exemple une porte ou plusieurs portes peuvent être équipées du dispositif selon le deuxième exemple de réalisation et les fenêtres peuvent être équipées du dispositif selon le premier exemple de réalisation.It may be planned to have a surveillance system for a dwelling containing several devices according to the present invention, in which the detection devices can all be identical or of different structures, for example a door or several doors can be equipped with the device according to the second embodiment and the windows can be equipped with the device according to the invention. first embodiment.

Sur les figures 7A et 7B, on peut voir un autre mode de réalisation d'un dispositif de détection selon la présente invention, adapté notamment aux fenêtres dans les toits, de type Velux®.In Figures 7A and 7B, we can see another embodiment of a detection device according to the present invention, particularly adapted to the windows in the roofs, Velux® type.

Ce type de fenêtre est équipé d'un ouvrant monté mobile en rotation autour d'un axe passant sensiblement au niveau de sa partie médiane.This type of window is equipped with an opening rotatably mounted about an axis passing substantially at its middle portion.

L'ouverture de ce type de fenêtre s'effectue par traction sur une poignée disposée le long d'un montant de l'ouvrant, le déplacement de cette poignée provoque le déplacement du pêne par rapport à la gâche, et le déverrouillage de l'ouvrant par rapport au cadre.The opening of this type of window is made by pulling on a handle disposed along an amount of the opening, the movement of this handle causes the bolt to move relative to the striker, and the unlocking of the opening relative to the frame.

Ce type de fenêtre peut être difficilement manipulable, notamment dans le cas de fenêtres de grandes dimensions. En effet, du fait du poids de l'ouvrant, celui-ci peut être difficilement retenu par une personne et celle-ci risque d'être entraînée par le mouvement de l'ouvrant. En outre, la fermeture de ce type de fenêtre nécessite de relever l'ouvrant, ce qui peut également être problématique.This type of window can be difficult to manipulate, especially in the case of large windows. Indeed, because of the weight of the opening, it can be difficult to retain a person and it may be driven by the movement of the opening. In addition, closing this type of window requires raising the door, which can also be problematic.

Pour cela, il a été envisagé d'assister l'ouverture et la fermeture des Velux® par un moteur électrique, qui lors de la manipulation de la poignée se met en route pour aider à la rotation dans un sens d'ouverture ou de fermeture de la fenêtre. Le moteur peut alors exercer un couple de rotation sur l'ouvrant au niveau de son axe, ou exercer un effort de traction ou de poussée sur l'ouvrant par un système de vis crémaillère montée à une extrémité de l'ouvrant.For this, it was envisaged to assist the opening and closing of the Velux® by an electric motor, which when handling the handle starts to help the rotation in a direction of opening or closing from the window. The motor can then exert a torque on the opening at its axis, or exert a pulling force or thrust on the opening by a screw rack system mounted at one end of the opening.

Habituellement, un dispositif de détection de déplacement rapporté sur l'ouvrant détecte le déplacement de la poignée par rapport à l'ouvrant.Usually, a displacement detection device attached to the opening detects the movement of the handle relative to the opening.

Grâce à la présente invention, ce dispositif de détection est directement intégré à la poignée et ne nécessite pas de dispositif de détection extérieur.Thanks to the present invention, this detection device is directly integrated into the handle and does not require an external detection device.

Il est alors prévu de réaliser une poignée composite formée par des parties électriquement conductrices qui sont, en position de repos, éloignées l'une de l'autre et qui, lors de la manipulation de la poignée, viennent en contact et ferment un circuit électrique relié à une unité de traitement qui enverra un signal d'activation au moteur électrique.It is then planned to produce a composite handle formed by electrically conductive parts which, in the rest position, are remote from one another and which, when the handle is being handled, come into contact and close an electrical circuit connected to a processing unit that will send an activation signal to the electric motor.

Sur les figures 7A et 7B, on peut voir un exemple de réalisation d'une telle poignée 40 comportant une première partie 42 et une deuxième partie 44 sensiblement parallèles et mobiles l'une par rapport à l'autre. La première partie 42 est fixée à l'encadrement de l'ouvrant (non représenté), et la deuxième partie 44 est montée articulée, par exemple sur la première partie ou sur le châssis de la fenêtre.FIGS. 7A and 7B show an exemplary embodiment of such a handle 40 comprising a first portion 42 and a second portion 44 that are substantially parallel and movable relative to each other. the other. The first part 42 is fixed to the frame of the opening (not shown), and the second part 44 is hinged, for example on the first part or on the frame of the window.

Chaque partie 42, 44 est de forme allongée, et comporte une saillie 46, 48 sensiblement dans sa partie centrale, en regard de la saillie 48, 46 de l'autre partie 44, 42.Each portion 42, 44 is of elongated shape, and has a projection 46, 48 substantially in its central part, facing the projection 48, 46 of the other portion 44, 42.

Les deux parties 42, 44 sont reliées à une unité de traitement 5.The two parts 42, 44 are connected to a processing unit 5.

Les parties de poignées 42, 44 sont élastiquement éloignées l'une de l'autre par des moyens élastiques 50. Ainsi sans effort contrant les efforts exercés par les moyens élastiques, les parties sont éloignées et le circuit électrique est ouvert.The handle portions 42, 44 are elastically spaced from each other by resilient means 50. Thus without effort countering the forces exerted by the elastic means, the parts are remote and the electrical circuit is open.

En cas de manipulation de la poignée, les parties 42, 44 se rapprochent, les saillies 46, 48 viennent en contact comme représenté sur la figure 7B, ce qui provoque la fermeture du circuit électrique et le passage du courant, qui est détecté par l'unité de traitement 5. L'unité de traitement 5 considère la fermeture du circuit comme une volonté d'ouvrir la fenêtre et envoie un signal approprié au moteur électrique ou à une source d'alimentation du moteur.In case of manipulation of the handle, the parts 42, 44 come closer, the projections 46, 48 come into contact as shown in Figure 7B, which causes the closing of the electrical circuit and the passage of the current, which is detected by the The processing unit 5 considers the closing of the circuit as a desire to open the window and sends a suitable signal to the electric motor or to an engine power source.

Ainsi, l'actionnement de la poignée est détecté sans utilisation d'un dispositif de détection extérieur, la poignée elle-même fait partie du dispositif de détection. Le système est alors simplifié et plus esthétique.Thus, the actuation of the handle is detected without the use of an external detection device, the handle itself is part of the detection device. The system is then simplified and more aesthetic.

La présente invention peut s'appliquer également à l'ouverture de porte de grandes dimensions, dont le déplacement manuel peut être difficile ou à l'ouverture de couvercle ou de coffre de véhicule automobile.The present invention can also be applied to the door opening of large dimensions, the manual movement can be difficult or the opening of the lid or trunk of a motor vehicle.

La forme des deux parties 42, 44 n'est pas limitée à la forme décrite, on peut prévoir par exemple des saillies à chacune des extrémités du corps allongé.The shape of the two parts 42, 44 is not limited to the form described, it can be provided for example projections at each end of the elongate body.

Les poignées, dans le cas du Velux, sont recouvertes d'un revêtement électriquement isolant, telle qu'une peinture. En outre, le circuit fonctionne à basse tension. Ainsi, les utilisateurs ne risquent pas de s'électrocuter.The handles, in the case of the Velux, are covered with an electrically insulating coating, such as a paint. In addition, the circuit operates at low voltage. Thus, the users are not likely to be electrocuted.

Cette remarque s'applique à toute mise en oeuvre de l'invention, dans lequel une protection électrique vis-à-vis des utilisateurs et/ou de l'environnement extérieur est requise.This remark applies to any implementation of the invention, in which electrical protection vis-à-vis the users and / or the external environment is required.

Sur les figures 8A à 8C, on peut voir une représentation schématique d'un premier exemple d'un troisième mode de réalisation d'un dispositif de détection de déplacement selon la présente invention appliqué à la surveillance d'objets, notamment de tableaux.In FIGS. 8A to 8C, a schematic representation of a first example of a third embodiment of a displacement detection device according to the present invention applied to the surveillance of objects, in particular tables, can be seen.

Un tableau peut, par exemple, être fixé par une tige à un câble tendu le long d'un mur. Ce câble peut faire tout le tour de la pièce et supporter plusieurs tableaux.For example, a table can be fixed by a rod to a cable stretched along a wall. This cable can go around the room and support several paintings.

Selon la présente invention, le dispositif de détection comporte deux conducteurs électriques 52, 54 parallèles destinés à supporter au moins un tableau 56, ces conducteurs électriques 52, 54, par exemple de type câble forment une partie d'un circuit électrique et sont reliés à une unité de traitement (non représentée).According to the present invention, the detection device comprises two parallel electrical conductors 52, 54 intended to support at least one panel 56, these electrical conductors 52, 54, for example of the cable type, form part of an electrical circuit and are connected to a processing unit (not shown).

Le tableau 56 est accroché aux câbles 52, 54 par l'intermédiaire d'une tige 58 fixée par une première extrémité 60 au tableau 56 et par une deuxième extrémité 62 aux câbles 52, 54. La deuxième extrémité 62 est en forme de crochet.The board 56 is hooked to the cables 52, 54 via a rod 58 fixed by a first end 60 to the board 56 and a second end 62 to the cables 52, 54. The second end 62 is hook-shaped.

Le dispositif de détection selon la présente invention comporte également un contacteur 64 interposé entre la tige 58 et les câbles 52,54, ce contacteur 64 est mobile relativement aux conducteurs électriques 52, 54.The detection device according to the present invention also comprises a contactor 64 interposed between the rod 58 and the cables 52, 54, this contactor 64 is movable relative to the electrical conductors 52, 54.

Le contacteur 64 comporte un corps 65 muni d'un côté de deux rainures 66, 68 recevant chacune un câble 52, 54, d'un téton 70 mobile dans le corps 65 et d'un élément 72 conducteur métallique destiné à relier électriquement les deux câbles 52, 54.The contactor 64 comprises a body 65 provided on one side with two grooves 66, 68 each receiving a cable 52, 54, a pin 70 movable in the body 65 and a metallic conductor element 72 for electrically connecting the two cables 52, 54.

L'élément conducteur 72 est maintenu en contact avec le téton 70 par un ressort 74.The conductive element 72 is held in contact with the stud 70 by a spring 74.

Sur la figure 8C, le téton 70 est au repos en saillie du corps 65 sous l'action du ressort 74In FIG. 8C, the stud 70 is at rest projecting from the body 65 under the action of the spring 74

Sur la figure 8B, un tableau 56 est accroché aux câbles, le crochet 62 appuie sur le téton 70 qui se déplace, le déplacement du téton 70 provoque le déplacement de l'élément 72, qui s'éloigne des câbles 52, 54. Le circuit électrique est ouvert.In FIG. 8B, a board 56 is hooked to the cables, the hook 62 presses on the pin 70 which moves, the displacement of the pin 70 causes the displacement of the element 72, which moves away from the cables 52, 54. electrical circuit is open.

Si le tableau 56 est retiré, le téton 70, du fait de l'effort du ressort 74, se déplace vers l'extérieur du corps 65, l'élément conducteur 72 vient en contact électrique avec les deux câbles 52, 54 et ferme le circuit électrique. Le courant peut alors circuler, l'unité de traitement envoie alors un signal d'absence du tableau.If the table 56 is removed, the pin 70, due to the force of the spring 74, moves outwardly of the body 65, the conductive member 72 comes into electrical contact with the two cables 52, 54 and closes the electrical circuit. The current can then flow, the processing unit then sends a signal of absence of the table.

Tous les tableaux accrochés aux câbles 52, 54, peuvent être équipés d'un tel dispositif de détection.All the boards attached to the cables 52, 54 may be equipped with such a detection device.

Sur les figures 9A à 9C et 10A à 10C, on peut voir un deuxième exemple de réalisation du troisième mode de réalisation d'un dispositif de détection selon la présente invention, dans lequel les câbles 52, 54 sont remplacés par une corniche formée de deux profilés en matériaux électriquement conducteurs isolés électriquement.FIGS. 9A to 9C and 10A to 10C show a second embodiment of the third embodiment of a detection device according to the present invention, in which the cables 52, 54 are replaced by a cornice formed of two profiles of electrically conductive electrically insulated materials.

Le dispositif de détection selon la présente invention comporte un support 76 pour accrocher un tableau 56 formant une corniche le long d'un mur 78.The detection device according to the present invention comprises a support 76 for hanging a table 56 forming a cornice along a wall 78.

Ledit support est formé par un élément inférieur 80 et un élément supérieur 82, de type profilés métalliques superposés, destinés à être fixés au mur 78.Said support is formed by a lower element 80 and an upper element 82, of superimposed metal profile type, intended to be fixed to the wall 78.

L'élément inférieur 80 comporte un tube 84 d'axe X1 à section rectangulaire comportant une rainure 86 axiale dans un côté 90 du tube 84.The lower element 80 comprises a tube 84 of axis X1 with a rectangular section having an axial groove 86 in a side 90 of the tube 84.

Un côté 92 orthogonal au côté 90 comportant la rainure 86, se prolonge par une plaque d'appui 94, de manière à former une embase destinée à venir en contact plan avec le mur 78.A side 92 orthogonal to the side 90 having the groove 86, is extended by a support plate 94, so as to form a base intended to come into plane contact with the wall 78.

L'élément supérieur 82 a sensiblement la même forme que celle de l'élément inférieur 80. Les références utilisées pour désigner les parties de l'élément 80 seront utilisées en ajoutant « ' », pour désigner les parties similaires de l'élément supérieur 82.The upper element 82 has substantially the same shape as that of the lower element 80. The references used to designate the parts of the element 80 will be used by adding "'", to denote similar parts of the upper element 82 .

L'élément supérieur 82 est disposé sur l'élément inférieur 80, de manière à ce que la rainure 86' soit en regard de la rainure 86.The upper element 82 is disposed on the lower element 80, so that the groove 86 'is opposite the groove 86.

L'élément supérieur comporte parallèlement à la plaque d'appui 94', une plaque 96' s'étendant d'un côté 100' parallèle au côté 92'.The upper element comprises parallel to the support plate 94 ', a plate 96' extending from one side 100 'parallel to the side 92'.

Des orifices 102' sont pratiqués dans un côté 104' opposé au côté 90' comportant la rainure 86', pour permettre le passage d'un doigt 200.Orifices 102 'are formed in a side 104' opposite the side 90 'having the groove 86', to allow passage of a finger 200.

Les plaques 94, 94' comportent des orifices 106, 106' de fixation des éléments supérieure 82 et inférieur 80 au mur 78.The plates 94, 94 'comprise orifices 106, 106' for fastening the upper elements 82 and lower 80 to the wall 78.

Un plongeur 202 est monté mobile dans le tube 84, orthogonalement à son axe, et fait saillie dans le tube 84' par les rainures 86, 86'.A plunger 202 is movably mounted in the tube 84, orthogonal to its axis, and protrudes into the tube 84 'through the grooves 86, 86'.

Le plongeur 202 apte à conduire le courant électrique, comporte à une extrémité inférieure une embase 204 disposée dans le tube 84 et à une extrémité supérieure un palpeur 206 dans le tube 84', en regard d'un orifice 102', le palpeur 206 étant destiné à venir en contact avec le doigt 200.The plunger 202 capable of conducting the electric current, comprises at a lower end a base 204 disposed in the tube 84 and at an upper end a feeler 206 in the tube 84 ', facing an orifice 102', the probe 206 being intended to come into contact with the finger 200.

Le plongeur 202 est ramené élastiquement en direction de l'orifice 102' par une moyen élastique 208, type ressort hélicoïdal monté en réaction entre un fond d'un alésage pratiqué dans l'embase 204 du plongeur 202 et le côté 104.The plunger 202 is resiliently returned towards the orifice 102 'by an elastic means 208, helical spring type mounted in reaction between a bottom of a bore formed in the base 204 of the plunger 202 and the side 104.

Le doigt 200 forme l'extrémité de la tige de suspension du tableau.The finger 200 forms the end of the suspension rod of the board.

Deux bandes 210 de matériau électriquement isolant sont disposées le long des rainures 86, 86' de manière à isoler les deux éléments supérieur 82 et inférieur 80.Two strips 210 of electrically insulating material are arranged along the grooves 86, 86 'so as to isolate the two upper elements 82 and lower 80.

Nous allons maintenant expliquer le fonctionnement du dispositif de détection.We will now explain the operation of the detection device.

Les deux profilés 80, 82, ainsi que le plongeur 202 font partie d'un circuit électrique alimenté par une unité de traitement (non représentée).The two sections 80, 82 and the plunger 202 are part of an electrical circuit powered by a processing unit (not shown).

Lorsqu'un effort vers le bas est appliqué sur le plongeur 202 par le doigt 200 tel que représenté sur la figure 10A, ce qui signifie qu'une charge est appliquée sur la tige de suspension par un tableau 56 suspendu, le plongeur 202 se trouve en position basse, le circuit électrique est alors ouvert. L'unité de traitement détecte alors la présence du tableau.When a downward force is applied to the plunger 202 by the finger 200 as shown in FIG. 10A, which means that a load is applied to the suspension rod by a suspended panel 56, the plunger 202 is located in the low position, the electrical circuit is then open. The processing unit then detects the presence of the array.

Par contre en l'absence de tableau, comme représenté sur la figure 10B, aucun effort ne s'applique sur le plongeur 202 à l'encontre du ressort 208, le plongeur 202 a alors une position haute, son embase vient en contact avec les bords de la rainure 86 du profilé 80 et le palpeur 206 vient en contact avec les contours de l'orifice 102'. Le circuit électrique est alors fermé, l'unité de traitement en déduit l'absence du tableau et génère alors un signal d'alarme.On the other hand, in the absence of a table, as shown in FIG. 10B, no force applies to the plunger 202 against the spring 208, the plunger 202 then has a high position, its base comes into contact with the edges of the groove 86 of the profile 80 and the probe 206 comes into contact with the contours of the orifice 102 '. The electrical circuit is then closed, the processing unit deduces the absence of the table and then generates an alarm signal.

Les profilés 80, 82 sont destinés à courir le long d'un mur ou de plusieurs murs d'une pièce pour supporter plusieurs tableaux. Il est alors prévu, dans le profilé supérieur 82, des orifices aux endroits où l'on souhaite accrocher les tableaux.The profiles 80, 82 are intended to run along a wall or several walls of a room to support several tables. It is then provided, in the upper profile 82, orifices where you want to hang the tables.

On peut également prévoir d'utiliser un support 76 pour un seul tableau.It is also possible to use a support 76 for a single table.

Les dispositifs de détection de présence des tableaux sont reliés électriquement en série. Ainsi, en l'absence d'un tableau l'unité de traitement va envoyer un signal d'alarme, alors que cette absence peut être due à une volonté de ne pas accrocher de tableau à cet endroit. Il est alors avantageusement prévu un dispositif pour exercer un effort sur le plongeur de manière à le maintenir en position basse, dont un exemple de réalisation est représenté sur la figure 10C.The presence detection devices of the arrays are electrically connected in series. Thus, in the absence of a table the processing unit will send an alarm signal, while this absence may be due to a desire not to hang an array at this location. It is then advantageously provided a device for exerting a force on the plunger so as to keep it in the low position, an exemplary embodiment of which is shown in FIG. 10C.

Celui-ci est formé dans l'exemple représenté par un corps 212 muni d'un téton 214 en saillie, de forme et de dimensions similaires à celles du doigt 200 de la tige de suspension et d'une goupille 216 destinée à pénétrer dans un alésage 218 prévu dans le corps 212 et un passage 220 pratiqué dans la plaque 96'.This is formed in the example shown by a body 212 provided with a protruding nipple 214, of similar shape and dimensions as the finger 200 of the suspension rod and a pin 216 intended to penetrate a bore 218 provided in the body 212 and a passage 220 formed in the plate 96 '.

Le téton 214 est alors maintenu appliqué contre le palpeur 206 par le montage de la goupille 216 dans l'alésage 218 et le passage 220.The pin 214 is then held pressed against the probe 206 by mounting the pin 216 in the bore 218 and the passage 220.

Ce dispositif forme ainsi un leurre pour le dispositif de détection.This device thus forms a decoy for the detection device.

Il peut être avantageux de prévoir que la tige 58 soit solidaire du tableau 56.It may be advantageous to provide that the rod 58 is integral with the board 56.

Les dispositifs mettant en oeuvre la présente invention fonctionnent avantageusement sous basse tension, par exemple inférieure à 5V et une intensité de courant comprise entre 1 pA et quelques ampères.The devices embodying the present invention operate advantageously at low voltage, for example less than 5V and a current intensity of between 1 pA and a few amperes.
