Description

L'invention concerne un dispositif de connexion destiné à être mis en oeuvre au niveau d'un mécanisme de fermeture de portes d'ascenseur notamment.The invention relates to a connection device intended to be implemented at the level an elevator door closing mechanism in particular.

Les normes de plus en plus drastique relatives au fonctionnement des ascenseurs, imposent notamment la mise en place de dispositifs de sécurité, propres à s'assurer de la fermeture correcte des portes au niveau des différents étages, préalablement au fonctionnement et notamment à la progression effective de l'ascenseur.The increasingly drastic standards relating to the operation of elevators, in particular require the installation of safety devices, capable of ensuring the correct closing of the doors on the different floors, prior to operation and in particular to the actual progression of the elevator.

En effet, outre la fermeture mécanique de la porte, ces normes requièrent dorénavant la genèse d'un signal électrique, acheminé au niveau de l'unité centrale de gestion gérant le fonctionnement effectif de l'ascenseur, et notamment la motorisation assurant sa progression au niveau des différents étages.Indeed, in addition to the mechanical closing of the door, these standards now require the generation of an electrical signal, sent to the central management unit the effective functioning of the elevator, and in particular the motorization ensuring its progression on the different floors.

Ce signal électrique est généré par un circuit électrique, solidarisé à la gâche de la porte de l'étage considéré, et susceptible d'être fermé par un circuit électrique complémentaire, associé au pêne de ladite porte.This electrical signal is generated by an electrical circuit, secured to the door strike of the floor considered, and capable of being closed by an electrical circuit complementary, associated with the bolt of said door.

Ainsi, lorsque la porte est correctement fermée, le circuit électrique du pêne, typiquement constitué d'un shunt vient fermer le circuit électrique associé à la gâche de la porte, et générant de par cette fermeture un signal électrique propre à autoriser le fonctionnement effectif de l'ascenseur.So, when the door is properly closed, the electrical circuit of the bolt, typically consisting of a shunt closes the electrical circuit associated with the striker the door, and generating by this closing an electrical signal suitable for authorizing the actual operation of the elevator.

Parmi les différents types de connecteurs de sécurité ainsi mis en oeuvre, on connaít un dispositif constitué d'un capot isolant, auquel aboutit le câble de connexion à l'unité centrale de gestion de l'ascenseur, et intégrant deux lames métalliques conductrices rigides et pré-pliées, constituant le circuit électrique précité. Ces deux lames sont solidarisées au support non conducteur par emboítage, la connexion électrique avec les fils électriques dudit câble précité étant assuré par vissage.Among the different types of safety connectors thus implemented, there is known a device consisting of an insulating cover, to which the cable for connection to the unit ends elevator management center, and incorporating two conductive metal blades rigid and pre-folded, constituting the above-mentioned electrical circuit. These two blades are secured to the non-conductive support by fitting, the electrical connection with electric wires of said cable being secured by screwing.

Le capot comporte en outre des picots dirigés vers l'intérieur du volume qu'il définit, propres à assurer le positionnement correct en termes de côte desdites lames, en vue de leur coopération avec le shunt, typiquement constitué d'une prise associée au pêne de la porte. The cover further comprises pins directed towards the inside of the volume which it defines, capable of ensuring correct positioning in terms of the rib of said blades, with a view to their cooperation with the shunt, typically consisting of a catch associated with the bolt the door.

Afin de permettre la fermeture efficace du circuit, c'est à dire la coopération du shunt avec l'extrémité libre des deux lames, le capot supérieur du support présente deux orifices oblongs, permettant le passage effectif de celui-ci.In order to allow the efficient closing of the circuit, i.e. the cooperation of the shunt with the free end of the two blades, the upper cover of the support has two oblong holes, allowing the effective passage thereof.

Si certes, ce connecteur de sécurité assure de manière satisfaisante la fonction qui lui est dévolue, il s'avère cependant coûteux à réaliser, compte tenu de la multiplicité des pièces qui le constituent, et engendre en outre une technique d'assemblage longue à mettre en oeuvre, compte-tenu notamment des moyens de fixation des lames au sein du support, et des moyens de connexion des fils électriques auxdites lames.If, of course, this safety connector satisfactorily performs the function which is devolved, it is however costly to carry out, given the multiplicity of component parts, and also generates a long assembly technique to implement, especially taking into account the means for fixing the blades within the support, and means for connecting the electrical wires to said blades.

L'objet de la présente invention est de proposer un connecteur de sécurité du type en question, à la fois simple à réaliser et a mettre en oeuvre, de telle sorte à baisser de manière drastique les coûts de revient.The object of the present invention is to provide a safety connector of the type question, both simple to carry out and to implement, so as to decrease by drastically the costs.

Un autre objet de la présente invention est de permettre l'adaptation de ce connecteur de sécurité à tout type d'environnement, lui conférant de fait un caractère modulaire.Another object of the present invention is to allow the adaptation of this connector safety in any type of environment, giving it a modular character.

Ce dispositif de connexion pour un mécanisme de fermeture de portes d'ascenseur notamment, comprend :

  • un premier ensemble de connexion solidarisé à la gâche de ladite porte comportant deux lames conductrices reliées chacune à un fil électrique d'un câble secteur, lui-même relié à l'organe d'activation de l'ascenseur ;
  • un second ensemble de connexion complémentaire du premier, solidarisé au pêne de la porte, et destiné à fermer le circuit électrique du premier ensemble de connexion afin de générer un signal autorisant ou au contraire interdisant l'activation de l'ascenseur.
This connection device for a mechanism for closing elevator doors in particular, comprises:
  • a first connection assembly secured to the keeper of said door comprising two conductive blades each connected to an electric wire of a power cable, itself connected to the activation member of the elevator;
  • a second connection assembly complementary to the first, secured to the bolt of the door, and intended to close the electrical circuit of the first connection assembly in order to generate a signal authorizing or on the contrary prohibiting the activation of the elevator.

Il se caractérise en ce que ledit premier ensemble de connexion comprend :

  • une partie standard, constituée par les deux lames conductrices, dont le voisinage de l'une des extrémités est surmoulée dans un matériau non conducteur, de telle sorte à constituer un bloc monolithique standard, l'extrémité libre desdites lames situées au voisinage du surmoulage étant connectée aux fils électriques du câble secteur ;
  • un support protecteur non conducteur de l'électricité, destiné à assurer le positionnement sur la gâche de la porte de ladite partie standard.
It is characterized in that said first connection assembly comprises:
  • a standard part, constituted by the two conductive strips, the vicinity of one of the ends of which is overmolded in a non-conductive material, so as to constitute a standard monolithic block, the free end of said blades situated in the vicinity of the overmolding being connected to the electrical wires of the power cable;
  • a non-electrically conductive protective support, intended to ensure positioning on the door strike of said standard part.

En d'autres termes, l'invention consiste tout d'abord à réaliser un bloc standard, constitutif du circuit électrique proprement dit, associé à un dispositif de connexion, mettant en oeuvre la technique du surmoulage, et à associer à celui-ci un capot ou support de protection et de positionnement sur la gâche de la porte de l'ascenseur considéré.In other words, the invention firstly consists in making a standard block, constituting the actual electrical circuit, associated with a connection device, using the overmolding technique, and associating a hood therewith or protection and positioning support on the keeper of the elevator door considered.

Selon l'invention, le surmoulage assure également la tenue du câble secteur, relié à l'organe d'activation de l'ascenseurAccording to the invention, the overmolding also ensures the strength of the power cable, connected to the elevator activation device

Selon l'invention, le support est constitué de deux parties complémentaires, assurant outre le maintien du câble secteur, également la fixation de la partie standard selon une configuration propre à assurer le contact effectif du shunt lors de sa mise en place, et le positionnement de l'extrémité libre desdites lames selon les côtes déterminées de fonctionnement.According to the invention, the support consists of two complementary parts, ensuring in addition to maintaining the power cable, also fixing the standard part according to a configuration suitable for ensuring effective contact of the shunt during its installation, and the positioning of the free end of said blades according to the determined ribs of operation.

Avantageusement, la partie standard est munie d'orifices de fixation additionnels sur l'une des parties du capot ou socle.Advantageously, the standard part is provided with additional fixing holes on one of the parts of the cover or base.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation qui suit donné à titre indicatif et non limitatif à l'appui des figures annexées.The manner in which the invention can be realized and the advantages which flow therefrom will emerge better from the example of embodiment which follows given by way of indication and not limiting in support of the appended figures.

Les figures 6, 7 et 8 sont des représentations schématiques vue de face, des lames conformes à d'autres formes de réalisation de l'invention. On a donc représenté schématiquement en relation avec la figure 1, une partie du dispositif de connexion conforme à la présente invention. Figures 6, 7 and 8 are schematic representations front view of the blades in accordance with other embodiments of the invention. So we represented schematically in relation to FIG. 1, part of the connection device according to the present invention.

La figure 9 est une représentation schématique vue du dessus d'une autre forme de réalisation de l'invention, dont la figure 10 est une vue en section.Figure 9 is a schematic representation seen from above of another form of embodiment of the invention, Figure 10 is a sectional view.

Il est rappelé à cet égard que si l'exemple qui suit est plus particulièrement décrit en relation avec un dispositif de sécurité pour portes d'ascenseur, il est bien entendu qu'il est susceptible d'être applicable à tout dispositif de sécurité propre à s'assurer la fermeture correcte d'une porte, quelle qu'elle soit.It is recalled in this regard that if the example which follows is more particularly described in relationship with a safety device for elevator doors, it is understood that is likely to be applicable to any safety device capable of ensuring the correct closing of any door.

Selon une première caractéristique fondamentale de l'invention, le dispositif de connexion et de sécurité comprend tout d'abord une partie standard (1) intégrant un circuit électrique constitué de deux lames conductrices métalliques (2) et (3), dont l'une des extrémités libres est connectée à un fil électrique conducteur, respectivement (8) et (9), acheminé à ce niveau par le câble secteur (7).According to a first fundamental characteristic of the invention, the device for connection and security first includes a standard part (1) incorporating a electrical circuit consisting of two metallic conductive strips (2) and (3), one of which free ends is connected to a conductive electrical wire, respectively (8) and (9), routed at this level by the power cable (7).

Ce câble secteur transmet l'information du circuit ainsi réalisé, à une unité centrale de gestion assurant le fonctionnement de l'installation considéré, notamment dans l'exemple décrit, le fonctionnement du ou des moteurs d'activation et de progression de l'ascenseur.This power cable transmits the information of the circuit thus produced, to a central unit of management ensuring the operation of the installation considered, in particular in the example described, the functioning of the activation and progression engine (s) from the elevator.

Ces deux lames conductrices (2) et (3) son identiques. Elles sont rigides et présentent une pliure, typiquement de l'ordre de 15°, de telle sorte à s'étendre selon deux directions concourantes, ainsi qu'on peut bien l'observer sur les figures 1 à 4.These two conductive strips (2) and (3) are identical. They are rigid and have a fold, typically of the order of 15 °, so as to extend in two concurrent directions, as can be seen in Figures 1 to 4.

L'extrémité libre desdites lames (2) et (3), opposée à leur extrémité assurant la connexion aux fils conducteurs (8) et (9), est munie d'une pastille ou rivet (25), par exemple du type bi-métallique, optimisant la qualité de la conduction électrique à ce niveau, lors de la fermeture de la porte par le shunt, comme décrit précédemment.The free end of said blades (2) and (3), opposite their end ensuring the connection to the conducting wires (8) and (9), is provided with a pad or rivet (25), by example of the bi-metallic type, optimizing the quality of electrical conduction at this level, when the door is closed by the shunt, as described above.

Selon une caractéristique de l'invention, ces deux lames sont surmoulées au voisinage de l'extrémité reliée au fil conducteur (8) et (9), par la technique du surmoulage bien connue, de sorte qu'il n'y a pas lieu de la décrire ici en détail.According to a characteristic of the invention, these two blades are molded in the vicinity of the end connected to the conducting wire (8) and (9), by the technique of overmolding well known, so there is no need to describe it here in detail.

Ce surmoulage assure également le maintien de la gaine du câble secteur (7) à ce niveau. This overmolding also maintains the sheath of the power cable (7) at this level.

Le matériau mis en oeuvre pour le surmoulage est typiquement du polyamide. Ce faisant, on isole les deux lames l'une de l'autre, et corollairement on assure leur positionnement précis, et en l'espèce parallèlement l'une à l'autre. Plus spécifiquement, ce surmoulage permet d'assurer l'isolation électrique d'une lame par rapport à l'autre, mais également leur positionnement géométrique respectif, au sein du dispositif de connexion. Seule une partie des lames respectives (2) et (3) émerge à l'extérieur du surmoulage pour permettre leur connexion effective aux fils conducteurs (8) et (9).The material used for overmolding is typically polyamide. This doing so, we isolate the two blades from each other, and as a corollary we ensure their precise positioning, and in this case parallel to each other. More specificly, this overmolding ensures electrical insulation of one blade from the other, but also their respective geometric positioning, within the system of connection. Only a part of the respective blades (2) and (3) emerges outside the overmolding to allow their effective connection to the conductive wires (8) and (9).

Selon une caractéristique avantageuse de l'invention, le bloc de surmoulage (4) ainsi réalisé peut présenter un orifice de positionnement (6) au niveau du socle (13) et du capot (12) constituant le support non conducteur du dispositif, pour permettre le positionnement précis de la partie standard ainsi réalisée, en vue notamment de la bonne coopération entre l'extrémité libre desdites lames (2) et (3) et le shunt de fermeture du circuit électrique ainsi constitué.According to an advantageous characteristic of the invention, the overmolding block (4) thus produced may have a positioning orifice (6) at the level of the base (13) and the cover (12) constituting the non-conductive support of the device, to allow the precise positioning of the standard part thus produced, with a view in particular to the correct cooperation between the free end of said blades (2) and (3) and the closing shunt of the electrical circuit thus constituted.

En outre, le bloc (4) peut également présenter des trous oblongs (5) de part et d'autre, assurant le cas échéant une zone de passage pour un moyen de fixation additionnel de type vis.In addition, the block (4) can also have oblong holes (5) on either side, if necessary ensuring a passage area for an additional fixing means of screw type.

Cette partie standard (1) est destinée à être reçue dans le support précité, comprenant donc une coque protectrice représentée plus en détail en relation avec la figure 2.This standard part (1) is intended to be received in the aforementioned support, comprising therefore a protective shell shown in more detail in relation to FIG. 2.

Celle-ci comprend typiquement deux parties (12) et (13), susceptibles de venir s'emboíter ou s'encliqueter l'une dans l'autre, notamment au moyen d'organes d'encliquetage (15) et (16), voire au moyen d'éléments additionnels non représentés.This typically comprises two parts (12) and (13), likely to come fitting or snapping into each other, in particular by means of members latching (15) and (16), or even by means of additional elements not shown.

Le bloc de surmoulage (4) proprement dit, est positionné au sein de l'ensemble coque + capot, au moyen de différentes saillies (17), et le cas échéant, au moyen d'un ergot de positionnement, respectivement (23) et (24) venant traverser l'orifice (6) décrit précédemment.The overmolding block (4) proper is positioned within the shell assembly + cover, by means of different projections (17), and if necessary, by means of a lug of positioning, respectively (23) and (24) passing through the orifice (6) described previously.

Cette coque est également munie d'une cloison transversale, respectivement (20) et (21), destinée à assurer la séparation effective des deux lames, et notamment leur cloisonnement, pour diminuer sinon limiter la formation de l'arc électrique susceptible de se constituer lors de la fermeture du circuit électrique constitué par les lames par le shunt associé au pêne de la porte considérée. This shell is also provided with a transverse partition, respectively (20) and (21), intended to ensure the effective separation of the two blades, and in particular their partitioning, to reduce if not limit the formation of the electric arc likely to be formed when the electrical circuit formed by the blades is closed by the shunt associated with the bolt of the door considered.

Outre sa fonction d'isolation, cette coque protectrice assure également, en coopértion avec le surmoulage, le maintien du câble secteur (7), par le biais d'orifices et de saillies appropriées référencés (14) sur la figure 2. Il permet également le passage du fil de terre contenu dans le conducteur (7) et destiné à être relié électriquement à la gâche.In addition to its insulation function, this protective shell also ensures, in cooperation with the overmolding, the maintenance of the power cable (7), through holes and projections appropriate referenced (14) in Figure 2. It also allows the passage of the wire earth contained in the conductor (7) and intended to be electrically connected to the strike.

La forme de cette coque protectrice peut être diverse, fonction de l'environnement au niveau duquel est susceptible d'être mis en place ce dispositif de connexion et de sécurité.The shape of this protective shell can be diverse, depending on the environment at level of which is likely to be implemented this connection device and security.

Elle est solidarisée à la gâche par tout moyen, tel que notamment par vissage.It is secured to the keeper by any means, such as in particular by screwing.

La face supérieure du capot (12) comporte en outre deux orifices oblongs (22), destinés, à l'instar des dispositifs connus de l'art antérieur, à permettre le passage du shunt pour coopérer avec les deux lames métalliques (2) et (3).The upper face of the cover (12) further comprises two oblong holes (22), intended, like the known devices of the prior art, to allow the passage of the shunt to cooperate with the two metal blades (2) and (3).

En outre, le capot (12) et le socle (13) sont munis de saillies s'étendant vers l'intérieur, respectivement (18) et (19), destinées à permettre le positionnement de la partie inclinée des lames métalliques (2) et (3), selon une côte bien déterminée dans l'espace, en vue de permettre une fermeture du circuit électrique par contact simultané ou quasiment simultané des deux extrémités libres des lames avec le shunt, monté sur le pêne de la porte considérée.In addition, the cover (12) and the base (13) are provided with projections extending inwards, respectively (18) and (19), intended to allow the positioning of the part inclined metal blades (2) and (3), according to a well determined dimension in space, to allow the electrical circuit to be closed by simultaneous contact, or almost simultaneous of the two free ends of the blades with the shunt, mounted on the bolt of the door considered.

Cette coque protectrice est également avantageusement réalisée en polyamide, éventuellement chargé.This protective shell is also advantageously made of polyamide, possibly loaded.

On a représenté en relation avec la figure 4, une vue schématique illustrant le positionnement des lames dans l'espace. Ainsi, la lame représentée en traits discontinus illustre son positionnement avant la pose du capot (12). La lame représentée en trait continu illustre sa place définitive, en appui contre le picot ou saillie (18), la lame étant donc ici en position de repos, c'est à dire, en l'absence du shunt.Is shown in relation to Figure 4, a schematic view illustrating the positioning of the blades in space. Thus, the blade represented in broken lines illustrates its positioning before fitting the cover (12). The blade shown in line continuous illustrates its final position, pressing against the spike or protrusion (18), the blade being so here in the rest position, that is, in the absence of the shunt.

De fait, une fois montées avec le bloc polyamide (4) de surmoulage, les lames de contact (2) et (3) sont en légère pression permanente avec les picots ou saillies (18) du capot (12), compte tenu de leur effet ressort. Le bloc (4) de surmoulage assure donc une fonction déterminante de positionnement des lames au sein de la coque protectrice. In fact, once assembled with the polyamide block (4) of overmolding, the blades of contact (2) and (3) are in slight permanent pressure with the pins or projections (18) of the cover (12), given their spring effect. The overmolding block (4) therefore ensures a decisive function for positioning the blades within the protective shell.

Compte-tenu de la géométrie identique de ces picots, ils permettent d'assurer un mouvement des lames simultanées. Corollairement, l'établissement du courant et son interruption s'effectue également au même instant t.Given the identical geometry of these pins, they make it possible to ensure a simultaneous blade movement. As a corollary, the establishment of the current and its interruption also takes place at the same time t.

On a représenté en relation avec les figures 5 à 8, différentes configurations possibles des lames proprement dites. Celles-ci sont donc conductrices d'électricité, et sont notamment réalisées en tout matériau conducteur de type CUPRO BERILIUM, BRONZE CHRYSOCALE, voire en acier inoxydable.There are shown in relation to Figures 5 to 8, different possible configurations blades themselves. These therefore conduct electricity, and are in particular made of any conductive material of the CUPRO BERILIUM type, BRONZE CHRYSOCALE, even in stainless steel.

Comme déjà dit, leur extrémité libre est munie d'un rivet bimétallique (25), cuivre / argent, afin d'assurer un meilleur contact électrique lors de la fermeture par le shunt.As already said, their free end is provided with a bimetallic rivet (25), copper / silver, to ensure better electrical contact when closing by the shunt.

Ce rivet est par exemple serti à l'extrémité libre de la lame, ainsi qu'on peut l'observer en figure 4.This rivet is for example crimped at the free end of the blade, as can be seen in figure 4.

La connexion effective des lames aux fils conducteurs (8) et (9) peut s'effectuer de différentes manières.The effective connection of the blades to the conductor wires (8) and (9) can be carried out different ways.

Une première solution consiste à dénuder l'extrémité libre des deux fils conducteurs (8, 9), et à sertir au niveau de cette zone dénudée un clip qui vient s'encliqueter sur l'extrémité de la lame émergeant du bloc de surmoulage (4). Dans cette hypothèse, ladite lame présente avantageusement au niveau de cette extrémité une zone non lisse (26), constituée par une succession de plis, destinée à optimiser le contact avec le clip de connexion sur le fil. On peut également envisager de surmouler l'assemblage clip-languette + fils + câble.A first solution consists in stripping the free end of the two conducting wires (8, 9), and to be crimped at the level of this bare area a clip which snaps onto the end of the blade emerging from the overmolding block (4). In this hypothesis, said blade advantageously has a non-smooth area at this end (26), constituted by a succession of folds, intended to optimize contact with the clip connection on the wire. We can also consider overmolding the clip-tab assembly + wires + cable.

Dans une autre variante, l'extrémité libre de la lame est munie d'ailes de sertissage (27), qui peuvent être directement serties sur les zones dénudées des fils.In another variant, the free end of the blade is provided with crimping wings (27), which can be directly crimped on the bare areas of the wires.

Dans cette hypothèse, les lames peuvent être réalisées en bandes enroulées sur bobine, à l'instar des connexions traditionnelles.In this hypothesis, the blades can be produced in strips wound on a reel, at like traditional connections.

De la même manière, la liaison du fil de masse (terre) avec le bâti acier sur lequel vient se fixer le dispositif de connexion peut présenter différentes variantes. In the same way, the connection of the ground wire (earth) with the steel frame on which comes fixing the connection device can have different variants.

Dans une première forme de réalisation, telle que représentée en relation avec les figures 2 et 3, l'extrémité libre du fil de terre est dénudée et reçoit un clip de connexion, raccordé sur une languette sertie à cette effet sur le bâti acier précité.In a first embodiment, as shown in relation to the Figures 2 and 3, the free end of the ground wire is stripped and receives a connection clip, connected on a tongue crimped for this purpose on the aforementioned steel frame.

Dans une autre variante, représentée en relation avec les figures 9 et 10, le bloc de surmoulage intègre un contact élastique conducteur (28), relié électriquement au fil de terre, et qui vient prendre appui au final quand ledit dispositif est fixé sur le bâti acier de la gâche.In another variant, shown in relation to FIGS. 9 and 10, the block of overmolding incorporates a conductive elastic contact (28), electrically connected to the wire earth, and which comes to bear ultimately when said device is fixed on the steel frame of the strike.

On conçoit tout l'intérêt du dispositif conforme à l'invention, dans la mesure où il permet de simplifier de manière drastique la réalisation, et sa mise en place définitive au niveau des portes dont on souhaite s'assurer, par le biais de la genèse d'un signal électrique, la fermeture correcte.We can understand the advantage of the device according to the invention, insofar as it allows to drastically simplify the implementation, and its final installation at level of the doors which one wishes to ensure, by means of the genesis of a signal electric, correct closing.
