Description

La présente invention concerne un parachute-guide pour ascenseur, ainsi que l'ascenseur ainsi équipé.The present invention relates to a parachute-guide for elevator, and the elevator thus equipped.

De manière connue, une cabine d'ascenseur circule dans une cage d'ascenseur entraînée par un moteur et des câbles de traction et guidée le long de rails généralement appelés guides. Un contrepoids également tracté par les câbles de traction est parfois prévu pour équilibrer la charge formée par la cabine. Généralement, la cabine est montée sur un châssis, appelé aussi arcade, sur lequel sont fixés des moyens de guidage, comme par exemple un jeu de galets ou un jeu de patins, destinés à coulisser le long de chaque guide et à assurer le guidage en translation de la cabine sur les guides. Ces moyens de guidage sont prévus pour remplir uniquement la fonction pour laquelle ils sont conçus.In known manner, an elevator car circulates in an elevator shaft driven by a motor and traction cables and guided along rails generally called guides. A counterweight also pulled by the traction cables is sometimes provided to balance the load formed by the cab. Generally, the cabin is mounted on a frame, also called an arch, on which are fixed guide means, such as a set of rollers or a set of pads, intended to slide along each guide and provide guidance in translation of the cabin on the guides. These guide means are intended to fulfill only the function for which they are designed.

Par ailleurs, afin de parer à de dangereux excès de vitesse de la cabine, sont également prévus des moyens de freinage de la cabine. Ces moyens sont habituellement appelés « parachutes ». La législation en matière de sécurité relative aux ascenseurs imposant un arrêt de la cabine pour une vitesse excessive, aussi bien dans le sens de la montée que dans le sens de la descente, la plupart des parachutes actuels disposent de moyens permettant le freinage de la cabine dans ces deux sens. De manière classique, le parachute agit sur le guide par coincement.Moreover, in order to avoid dangerous speeding of the car, braking means of the car are also provided. These means are usually called parachutes. The safety legislation relating to lifts imposing a stopping of the cabin for excessive speed, as well in the direction of the ascent in the direction of descent, most current parachutes have means for braking the cabin in both directions. In a conventional manner, the parachute acts on the guide by wedging.

Le document FR-A-2 242318 divulgue un parachute-guide pour une cabine d'ascenseur circulant le long d'un guide à l'aide d'un système de guidage et comportant un système de parachute commandé par un système de déclenchement. Le système de parachute se présente sous la forme d'une came appuyant sur le guide.The document FR-A-2 242318 discloses a guide parachute for an elevator car traveling along a guide with a guidance system and having a parachute system controlled by a trigger system. The parachute system is in the form of a cam pressing on the guide.

Ainsi, parmi les parachutes existants, on connaît des systèmes composés de coins. C'est par exemple le cas du document de brevet US-A-5 964 320 qui décrit le freinage d'une cabine d'ascenseur munie d'un système de coins fixes et de coins mobiles. Dans ce système, le freinage est obtenu par coulissement des coins mobiles le long de rampes formées par les coins fixes jusqu'à aboutir au coincement des coins mobiles entre les coins fixes. A l'aide de ce système de coins, on obtient un freinage puis un blocage de la cabine d'ascenseur sur ses guides.Thus, among the existing parachutes, there are known systems composed of corners. This is the case, for example, of the US-A-5,964,320 which describes the braking of an elevator car with a system of fixed corners and moving corners. In this system, the braking is obtained by sliding the movable corners along ramps formed by the fixed corners to result in the wedging of the movable corners between the fixed corners. Using this system of corners, we obtain a braking and a blockage of the elevator car on its guides.

Il existe également des parachutes faisant intervenir un galet de coincement. Le principe de ce type de parachute est que le galet est prévu pour coulisser le long d'une rampe inclinée en direction du guide. Ainsi, lorsque le parachute est enclenché, le galet s'insère progressivement entre la rampe et le guide afin de réaliser progressivement le freinage, puis le blocage de la cabine. Un patin fixe situé de l'autre côté du guide est prévu pour contrebalancer la poussée engendrée par le galet. Ce type de parachute est par exemple illustré dans le document FR-A-2 689 113 .There are also parachutes involving a wedge pinch. The principle of this type of parachute is that the roller is provided to slide along an inclined ramp towards the guide. Thus, when the parachute is engaged, the roller is inserted gradually between the ramp and the guide to gradually achieve the braking, then the blocking of the cabin. A fixed pad located on the other side of the guide is provided to counterbalance the thrust generated by the roller. This type of parachute is for example illustrated in the document FR-A-2,689,113 .

Le déclenchement des parachutes d'une cabine est habituellement réalisé par un système de déclenchement constitué d'une poulie entraînée en rotation par des câbles fixés à la cabine. Elle est par exemple placée dans la salle des machines au sommet de la cage d'ascenseur. Elle est pourvue de masselottes qui, lorsque sa vitesse de rotation dépasse une vitesse seuil prédéterminée, sont plaquées à la périphérie de la poulie dans des logements prévus pour les recevoir. Dans cette position, les masselottes commandent le système de freinage de la cabine, ce qui a pour effet de la stopper sur les guides.The triggering of the parachutes of a cabin is usually performed by a trigger system consisting of a pulley rotated by cables fixed to the cabin. For example, it is placed in the engine room at the top of the elevator shaft. It is provided with flyweights which, when its rotational speed exceeds a predetermined threshold speed, are pressed to the periphery of the pulley in housings intended to receive them. In this position, the weights control the braking system of the cabin, which has the effect of stopping on the guides.

Lors du montage de l'ascenseur, chacun des éléments précédents, à savoir le système de guidage de la cabine, le système de freinage ou parachute et le limiteur de vitesse notamment, nécessite sa propre durée d'installation et des moyens adaptés à son installation. Le limiteur de vitesse notamment nécessite une installation de câbles s'étendant depuis le haut de la cage d'ascenseur jusqu'au système d'actionnement du parachute. La multiplicité des endroits d'intervention et la diversité des systèmes à mettre en place peuvent s'avérer fastidieuses. En outre, l'ensemble du câblage s'avère encombrant et de l'espace doit être prévu pour son installation dans la cage d'ascenseur.When mounting the elevator, each of the preceding elements, namely the cabin guidance system, the braking system or parachute and the speed limiter in particular, requires its own installation time and means adapted to its installation . The speed limiter in particular requires a cable installation extending from the top of the elevator shaft to the parachute actuation system. The multiplicity of places of intervention and the diversity of the systems to be put in place can be tedious. In addition, all the wiring is bulky and space must be provided for its installation in the elevator shaft.

Le but de l'invention est donc de proposer un dispositif du type boîtier incorporant un système de parachute, un système de guidage et un système de déclenchement du système de parachute pouvant être montés sur le châssis entourant la cabine d'ascenseur de manière à faciliter le montage, l'implantation et l'utilisation de ces systèmes.The object of the invention is therefore to propose a device of the box type incorporating a parachute system, a guidance system and a trigger system of the parachute system that can be mounted on the frame surrounding the elevator car so as to facilitate the assembly, implementation and use of these systems.

On a représenté à la Fig. 1 l'intérieur d'une cage d'ascenseur. Dans cette cage d'ascenseur sont représentés une cabine d'ascenseur 1 tronquée longitudinalement et transversalement, deux guides 3 dont la section en « T » est formée d'une âme 3a permettant le guidage et de deux ailes 3b servant de support et deux parachutes-guides 2 respectivement placés sur les parois des côtés du châssis (non représenté) de la cabine 1, entre ce châssis et un guide 3. On notera qu'un parachute-guide selon l'invention peut également être placé sur le contrepoids, par exemple lorsque la cage d'ascenseur comporte une cave. Le parachute-guide 2 est représenté plus en détail sur les Figs. 2 à 8 suivantes.We have shown Fig. 1 inside an elevator shaft. In this elevator shaft are represented an elevator car 1 truncated longitudinally and transversely, two guides 3 whose section "T" is formed of a core 3a for guiding and two wings 3b serving as support and two parachutes -guides 2 respectively placed on the walls of the sides of the chassis (not shown) of the cabin 1, between this frame and a guide 3. It will be noted that a parachute-guide according to the invention can also be placed on the counterweight, for example when the elevator shaft comprises a cellar. The parachute-guide 2 is shown in more detail on the Figs. 2 to 8 following.

A la Fig. 2, sont représentés selon différents plans transversaux, un guide 3 ainsi que les différentes parties constitutives d'un parachute-guide 2 selon la présente invention. Sur cette Fig, 2, on remarque qu'un parachute-guide 2 selon l'invention comporte un socle 4 dans lequel sont insérés, d'une part, dans un premier plan A, un système de guidage 5 et, d'autre part dans un second plan B, un système de parachute 6. Le socle 4 comprend deux parties 40a, 40b séparées entre elles par une rainure 41 le traversant verticalement de part en part. Cette rainure 41 est prévue pour permettre le passage de l'âme 3a du guide 3. En outre, les parois 410a et 410b des parties respectives 40a et 40b donnant sur la rainure 41 sont ouvertes de moitié de manière à permettre au système de guidage 5 et au système de parachute 6 d'accéder au guide 3.To the Fig. 2 , are represented in different transverse planes, a guide 3 as well as the various constituent parts of a guide parachute 2 according to the present invention. On this Fig, 2 it should be noted that a parachute-guide 2 according to the invention comprises a base 4 in which are inserted, firstly, in a first plane A, a guide system 5 and, secondly, in a second plane B , a parachute system 6. The base 4 comprises two parts 40a, 40b separated from each other by a groove 41 passing vertically from one side to the other. This groove 41 is provided to allow the passage of the web 3a of the guide 3. In addition, the walls 410a and 410b of the respective parts 40a and 40b giving onto the groove 41 are half open so as to allow the guiding system 5 and the parachute system 6 to access the guide 3.

Le système de guidage 5 représenté à la Fig. 3. comporte de part et d'autre de l'âme 3a du guide 3, un galet droit 50a et un galet gauche 50b respectivement montés à rotation sur des arbres 51a et 51b par l'intermédiaire de moyens de roulement 52a et 52b. L'arbre 51a du galet droit 50a est fixé sur la partie 40a du socle 4. Quant à l'arbre 51b du galet gauche 50b, il est fixé à l'extrémité libre d'un levier 53b monté sur la paroi horizontale basse 4a du socle 4 à pivotement autour d'un axe parallèle à l'axe de rotation du galet 50b. Un élément élastique de compression 55b fixé sur ce levier 53b et prenant appui contre la paroi verticale gauche 4b du socle 4 exerce une force de rappel sur le levier 53b qui tend à l'éloigner de la paroi verticale gauche 4b du socle 4. Se faisant, le galet gauche 50b est contraint à prendre un appui forcé contre l'âme 3a du guide 3 qui se trouve ainsi enserrée entre les deux galets de guidage 50a, 50b. Ainsi, est assurée la fonction de guidage avant-arrière de la cabine.The guiding system 5 shown in FIG. Fig. 3 . comprises on either side of the web 3a of the guide 3, a right roller 50a and a left roller 50b respectively rotatably mounted on shafts 51a and 51b by means of rolling means 52a and 52b. The shaft 51a of the right roller 50a is fixed on the part 40a of the base 4. As for the shaft 51b of the left roller 50b, it is fixed to the free end of a lever 53b mounted on the low horizontal wall 4a of the base 4 pivoting about an axis parallel to the axis of rotation of the roller 50b. An elastic compression element 55b fixed on this lever 53b and bearing against the left vertical wall 4b of the base 4 exerts a restoring force on the lever 53b which tends to move it away from the left vertical wall 4b of the base 4. Being , the left roller 50b is forced to take a forced support against the web 3a of the guide 3 which is thus sandwiched between the two guide rollers 50a, 50b. Thus, is ensured the front-rear guide function of the cabin.

Un patin de guidage 42 est prévu au fond de la rainure 41 pour recevoir l'extrémité libre de l'âme 3a du guide 3 et assurer ainsi le guidage latéral de la cabine 1.A guide pad 42 is provided at the bottom of the groove 41 to receive the free end of the web 3a of the guide 3 and thus provide lateral guidance of the cabin 1.

Situé dans le plan B du parachute-guide 2 selon l'invention, le système de parachute 6 est également réparti de part et d'autre de l'âme 3a du guide 3. Ce système de parachute 6 est représenté à la Fig. 4 dans sa position de repos. Cette position de repos est celle qu'il adopte lors du déplacement de la cabine 1 à vitesse normale, comme on le verra par la suite. Le système de parachute 6 comporte, installé dans la partie 40a du socle 4 à droite sur la Fig. 4, un système de freinage 6a et dans la partie 40b du socle 4 à gauche, un système de contrebalancement du freinage 6b.Located in the plane B of the parachute-guide 2 according to the invention, the parachute system 6 is equally distributed on either side of the core 3a of the guide 3. This parachute system 6 is shown at the Fig. 4 in his rest position. This rest position is the one he adopts when moving cabin 1 at normal speed, as will be seen later. The parachute system 6 comprises, installed in the part 40a of the base 4 on the right on the Fig. 4 , a braking system 6a and in the part 40b of the base 4 on the left, a braking counterbalancing system 6b.

Le système de contrebalancement du freinage 6b comporte une platine 60 constituée d'un bloc parallélépipédique dont la face tournée vers le guide 3 présente une forme de V de manière à ménager deux pointes d'appui 60a et 60b. Sur ces pointes d'appui 60a et 60b, est fixé, de préférence par des tétons 620, un moyen élastique de flexion 62, prenant ici la forme avantageuse de lames souples de taille décroissante avec l'éloignement de la platine 60. Les deux pointes 60a et 60b ménagent un espace à l'intérieur du V pour le débattement du moyen élastique 62.The counterbalancing system braking 6b comprises a plate 60 consisting of a parallelepiped block whose side facing the guide 3 has a V-shaped so as to provide two bearing points 60a and 60b. On these bearing points 60a and 60b, is preferably fixed by pins 620, an elastic bending means 62, here taking the advantageous form of flexible blades of decreasing size with the distance of the plate 60. The two points 60a and 60b provide a space inside the V for the deflection of the elastic means 62.

Le moyen élastique 62 porte un patin 64 dans un matériau avantageusement à fort coefficient de frottement avec le guide 3 ou un matériau métallique dur. Le patin 64 et le moyen élastique 62 sont avantageusement liés l'un à l'autre par une plaque 63.The elastic means 62 carries a shoe 64 in a material advantageously with a high coefficient of friction with the guide 3 or a hard metal material. The pad 64 and the elastic means 62 are advantageously connected to one another by a plate 63.

La platine 60 est emmanchée avec jeu sur les extrémités lisses de deux vis 61 vissées dans la paroi verticale gauche 4b du socle 4. Des contre-écrous 61 a assurent le blocage des vis 61. La platine 60 est en butée contre les vis 61 qui assurent son positionnement vis-à-vis de l'âme 3a du guide 3.The plate 60 is fitted with play on the smooth ends of two screws 61 screwed into the vertical left wall 4b of the base 4. Locknuts 61a ensure the locking of the screws 61. The plate 60 abuts against the screws 61 which ensure its positioning vis-à-vis the soul 3a of the guide 3.

Quant au système de freinage 6a, il comprend un organe de freinage 67a prévu pour pouvoir pivoter autour d'un axe situé dans un plan normal à l'axe longitudinal du guide 3 et parallèle à l'âme 3a et distant de celle-ci. Cet axe est, dans l'exemple de réalisation représenté, matérialisé par l'arbre 51a du galet de guidage droit 50a. L'organe 67a est pourvu à sa périphérie dans une zone proche du guide 3 symétriquement de part et d'autre d'un axe horizontal passant par son axe de pivotement d'un patin de freinage bas 670b et d'un patin de freinage haut 670a.As for the braking system 6a, it comprises a braking member 67a provided to be pivotable about an axis located in a plane normal to the longitudinal axis of the guide 3 and parallel to the core 3a and remote thereof. This axis is, in the exemplary embodiment shown, materialized by the shaft 51a of the right guide roller 50a. The member 67a is provided at its periphery in an area near the guide 3 symmetrically on either side of a horizontal axis passing through its pivot axis of a low braking pad 670b and a high braking pad 670a.

L'organe de freinage 67a est commandé, par un système de déclenchement approprié, comme on le verra par la suite, pour pouvoir pivoter autour de l'arbre 51a dans le sens trigonométrique ou dans le sens inverse selon que la cabine 1 acquière une vitesse excessive respectivement dans le sens de la montée ou dans le sens de la descente.The braking member 67a is controlled by a suitable triggering system, as will be seen later, to be able to pivot about the shaft 51a in the counterclockwise direction or in the opposite direction depending on whether the cabin 1 acquires a speed excessive in the direction of ascent or in the direction of descent.

S'il pivote dans le sens inverse du sens trigonométrique, le patin bas 670b entre en appui forcé contre l'âme 3a du guide 3. Par contre, s'il pivote dans le sens trigonométrique, c'est le patin haut 670a qui entre en appui forcé contre l'âme 3a du guide 3. Dans l'un ou l'autre cas, l'âme 3a se trouve alors prise en tenaille entre d'une part, un patin de freinage 670a, 670b de l'organe de freinage 67a et, d'autre part, le patin de contrebalancement 64 situé de l'autre côté de l'âme 3a. Il en résulte un coincement progressif de la cabine 1 qui s'arrête sur une distance proportionnelle à la raideur du moyen élastique 62.If it pivots in counterclockwise direction, the bottom pad 670b comes into force against the soul 3a of the guide 3. On the other hand, if it pivots in the trigonometrical direction, it is the upper pad 670a which enters in one or the other case, the soul 3a is then caught between a hand, a braking pad 670a, 670b of the body member. braking 67a and, on the other hand, the counterbalancing pad 64 located on the other side of the core 3a. This results in a progressive jamming of the cabin 1 which stops over a distance proportional to the stiffness of the elastic means 62.

On notera que dans cette position de freinage, chaque patin 670a, 670b, de par sa forme et sa position sur l'organe de freinage 67a, a sa face en appui contre le guide 3 qui présente un angle aigu par rapport à l'axe longitudinal de ce guide et qu'ainsi, il est coincé, son mouvement n'étant pas en lui-même réversible.Note that in this braking position, each pad 670a, 670b, by its shape and its position on the braking member 67a, has its face bearing against the guide 3 which has an acute angle with respect to the axis longitudinal of this guide and thus, it is stuck, its movement is not in itself reversible.

La force de coincement des patins 670a et 670b sur le guide 3, lorsqu'ils sont en position de freinage, est donnée, par réaction, par le moyen élastique de flexion 62 via le patin 64. Cette force de coincement est progressive, elle augmente au fur et à mesure que la cabine 1 ralentit. La vitesse de coincement est rendue réglable par le positionnement du moyen élastique 62 par rapport au guide 3 à l'aide des vis 61.The wedging force of the shoes 670a and 670b on the guide 3, when in the braking position, is given, by reaction, by the elastic bending means 62 via the shoe 64. This clamping force is progressive, it increases as cabin 1 slows down. The jamming speed is made adjustable by the positioning of the elastic means 62 relative to the guide 3 by means of the screws 61.

On va maintenant décrire deux modes de réalisation d'un système de déclenchement de l'organe de freinage 67a.Two embodiments of a triggering system of the braking member 67a will now be described.

Selon le premier mode de réalisation, le système de déclenchement comporte une première bielle 68a dont une première extrémité comporte une articulation 681 sur l'organe de freinage 67a et dont la deuxième extrémité est articulée en 682 à une première extrémité d'une seconde bielle 68b. Cette seconde bielle 68b est elle-même articulée, d'une part, au niveau de sa seconde extrémité, via un pivot 690a, au noyau plongeur 69a d'un premier électroaimant 70a et, d'autre part, dans une zone proche de son milieu, via un pivot 690b, au noyau plongeur 69b d'un second électroaimant 70b. L'ensemble constitué par les électroaimants 70 et les bielles 68 forme un organe de commande 67b de l'organe de freinage 67a.According to the first embodiment, the tripping system comprises a first connecting rod 68a whose first end comprises a hinge 681 on the braking member 67a and whose second end is hinged at 682 at a first end of a second rod 68b . This second connecting rod 68b is itself hinged, on the one hand, at its second end, via a pivot 690a, to the plunger core 69a of a first electromagnet 70a and, on the other hand, in an area close to its middle, via a pivot 690b, the plunger 69b of a second electromagnet 70b. The assembly constituted by the electromagnets 70 and the links 68 forms a control member 67b of the braking member 67a.

Dans ce mode de réalisation tel qu'il est représenté, l'organe de freinage 67a est constitué d'un disque qui est pourvu sur une partie de sa périphérie d'une gorge 671 en arc de cercle. Cette gorge 671 loge l'extrémité de la première bielle 68a lors de ses différents mouvements dus aux pivotements de l'organe de freinage 67a.In this embodiment as shown, the braking member 67a consists of a disk which is provided on a portion of its periphery with a groove 671 in an arc. This groove 671 houses the end of the first connecting rod 68a during its various movements due to the pivoting of the braking member 67a.

On a représenté à la Fig. 5 le système de parachute 6 en position de blocage suite à une vitesse excessive lors de la descente de la cabine 1 le long du guide 3. Dans ce cas, seul le second électroaimant 70b est excité, ce qui a pour effet de commander la plongée de son noyau plongeur 69b, alors que le noyau plongeur 69a du premier électroaimant 70a reste dans sa position de repos. La seconde bielle 68b pivote alors par rapport au pivot 690a et entraîne la première bielle 68a dans un mouvement vers le bas. Cette première bielle 68a entraîne l'organe de freinage 67a en pivotement autour de l'arbre 51a dans le sens inverse du sens trigonométrique, si bien que le patin bas 670b, comme on l'a vu précédemment, vient se coincer sur l'âme 3a du guide 3.We have shown Fig. 5 the parachute system 6 in the blocking position due to an excessive speed during the descent of the cabin 1 along the guide 3. In this case, only the second electromagnet 70b is excited, which has the effect of controlling the dive of its plunger core 69b, while the plunger core 69a of the first electromagnet 70a remains in its rest position. The second link 68b then pivots relative to the pivot 690a and drives the first link 68a in a downward movement. This first connecting rod 68a causes the braking member 67a to pivot about the shaft 51a in the opposite direction of the trigonometric direction, so that the lower pad 670b, as previously seen, is jammed on the core 3a of the guide 3.

A la Fig. 6, on a représenté le système de parachute 6 en position de blocage suite à une vitesse excessive lors de la montée de la cabine 1 le long du guide 3. Dans ce cas, seul l'électroaimant 70a est excité et son noyau 69a plonge alors. La seconde bielle 68b pivote autour du pivot 690b et entraîne la première bielle 68a dans un mouvement vers le haut. Cette première bielle 68a entraîne l'organe de freinage 67a en pivotement autour de l'arbre 51a dans le sens trigonométrique, si bien que le patin haut 670a vient se coincer sur l'âme 3a du guide 3.To the Fig. 6 , the parachute system 6 is shown in the blocking position due to an excessive speed during the rise of the cabin 1 along the guide 3. In this case, only the electromagnet 70a is excited and its core 69a then plunges. The second link 68b pivots about the pivot 690b and drives the first link 68a in an upward motion. This first connecting rod 68a causes the braking member 67a to pivot about the shaft 51a in the counterclockwise direction, so that the top pad 670a is jammed on the web 3a of the guide 3.

On décrit maintenant en relation avec la Fig. 7 des moyens de commande qui peuvent être utilisés pour commander les électroaimants 70a et 70b. Ces moyens de commande comprennent une unité de commande électronique E qui délivre des signaux de commande à des interrupteurs 71a et 71b pour respectivement exciter les électroaimants 70a et 70b, une dynamo D qui délivre une tension continue V liée à sa vitesse de rotation et à son sens de rotation et qui est fournie, d'une part, à une entrée de l'unité de commande E et, d'autre part, à une entrée d'une unité d'alimentation A prévue pour alimenter électriquement les électroaimants 70a et 70b, ainsi que l'unité de commande E. L'unité de commande E comporte deux autres entrées sur lesquelles sont respectivement appliquées une tension de référence négative Ref- et une tension de référence positive Ref+.We now describe in relation to the Fig. 7 control means that can be used to control the electromagnets 70a and 70b. These control means comprise an electronic control unit E which delivers control signals to switches 71a and 71b respectively to excite the electromagnets 70a and 70b, a dynamo D which delivers a DC voltage V related to its rotation speed and its direction of rotation which is supplied, on the one hand, to an input of the control unit E and, on the other hand, to an input of a power supply unit A provided for electrically feeding the electromagnets 70a and 70b as well as the control unit E. The control unit E has two other inputs on which a negative reference voltage Ref - and a positive reference voltage Ref + respectively are applied.

Lorsque la tension V délivrée par la dynamo D est comprise entre la tension de référence négative Ref- et la tension de référence positive Ref+, l'unité de commande E est au repos et ne pilote pas les interrupteurs 71a et 71b.When the voltage V delivered by the dynamo D is between the negative reference voltage Ref - and the positive reference voltage Ref + , the control unit E is at rest and does not control the switches 71a and 71b.

Lorsque la tension V délivrée par la dynamo D devient supérieure à la tension de référence positive Ref+ , l'unité de commande E pilote l'interrupteur 71b, ce qui a pour effet de commander l'électroaimant 70b.When the voltage V delivered by the dynamo D becomes greater than the positive reference voltage Ref + , the control unit E drives the switch 71b, which has the effect of controlling the electromagnet 70b.

Lorsque la tension V délivrée par la dynamo D devient inférieure à la tension de référence négative Ref-, l'unité de commande E pilote l'interrupteur 71a, ce qui a pour effet de commander l'électroaimant 70a.When the voltage V delivered by the dynamo D becomes lower than the negative reference voltage Ref - , the control unit E drives the switch 71a, which has the effect of controlling the electromagnet 70a.

La dynamo D est montée sur l'arbre 51b de manière à pouvoir être entraînée en rotation par le galet 50b (voir Fig. 3). Ainsi, la tension V qu'elle délivre est fonction (voire proportionnelle) de la vitesse de rotation du galet 50b et, par conséquent, de la vitesse de la cabine 1 sur les guides 3. Le signe de cette tension est également représentatif du sens de déplacement de la cabine 1.The dynamo D is mounted on the shaft 51b so as to be rotated by the roller 50b (see Fig. 3 ). Thus, the voltage V that it delivers is a function (or even proportional) of the speed of rotation of the roller 50b and, consequently, of the speed of the car 1 on the guides 3. The sign of this voltage is also representative of the direction moving the cab 1.

Ainsi, à vitesse normale de la cabine 1, aussi bien dans un sens que dans l'autre, la tension V délivrée par la dynamo D est comprise entre la tension de référence négative Ref- et la tension de référence positive Ref+. Les électroaimants 70a et 70b ne sont pas excités et l'on se trouve dans la situation montrée à la Fig. 4.Thus, at normal speed of the cabin 1, both in one direction and the other, the voltage V delivered by the dynamo D is between the negative reference voltage Ref - and the positive reference voltage Ref + . The electromagnets 70a and 70b are not excited and one is in the situation shown in FIG. Fig. 4 .

Lorsque la cabine 1 atteint une vitesse de déplacement en descendant telle que la tension V délivrée par la dynamo D est supérieure à la tension de référence positive Ref+, l'électroaimant 70b est excité et l'on se retrouve dans la situation montrée à la Fig. 5.When the cabin 1 reaches a downward traveling speed such that the voltage V delivered by the dynamo D is greater than the positive reference voltage Ref + , the electromagnet 70b is excited and one finds oneself in the situation shown in FIG. Fig. 5 .

Lorsque la cabine 1 atteint une vitesse de déplacement en montant telle que la tension V délivrée par la dynamo D est inférieure à la tension de référence négative Ref-, l'électroaimant 70a est excité et l'on se retrouve dans la situation montrée à la Fig. 6.When the cabin 1 reaches a traveling speed ascending such that the voltage V delivered by the dynamo D is lower than the negative reference voltage Ref - , the electromagnet 70a is excited and one finds oneself in the situation shown in FIG. Fig. 6 .

On notera que ce sont les tensions de référence Ref- et Ref+ qui définissent les seuils de vitesses excessives respectivement en descendant et en montant.It should be noted that reference voltages Ref - and Ref + define the thresholds of excessive speeds respectively downward and upward.

Selon l'invention, les parachutes-guides 2 sont reliés entre eux par des câbles prévus pour permettre la communication des parachutes-guides 2 entre eux. Ainsi, lorsqu'un écart anormal de tension ΔV est mesuré entre les dynamos D de chacun des parachutes-guides mis en place sur la cabine ou sur la cabine et le contrepoids, les parachutes-guides sont déclenchés de manière approximativement simultanée.According to the invention, the guide parachutes 2 are interconnected by cables provided to allow the communication of the guide parachutes 2 between them. Thus, when an abnormal deviation of tension ΔV is measured between the dynamos D of each of the guide parachutes set up on the cab or the cab and the counterweight, the guide parachutes are triggered approximately simultaneously.

L'unité d'alimentation A est telle que lorsque la tension d'alimentation U de la cabine est présente, c'est elle qui alimente les électroaimants 70a et 70b, ainsi que l'unité de commande E. Lorsqu'elle n'est pas présente, c'est celle qui est délivrée par la dynamo D qui est utilisée. Ainsi, dans le cas où la cabine n'est plus alimentée, le système de parachute 6 du parachute-guide fonctionne toujours grâce à l'alimentation fournie par la dynamo D.The power supply unit A is such that when the power supply voltage U of the cabin is present, it is it which supplies the electromagnets 70a and 70b, as well as the control unit E. When it is not present, it is the one that is delivered by the dynamo D which is used. Thus, in the case where the cabin is no longer powered, the parachute system 6 of the parachute-guide still works thanks to the power supply provided by the dynamo D.

Un second système de déclenchement Dm du type mécanique pour la commande de l'organe de freinage 67a du système de parachute est maintenant décrit en relation avec les Figs. 8 et 9.A second triggering system Dm of the mechanical type for controlling the braking member 67a of the parachute system is now described in relation to the Figs. 8 and 9 .

Le système de déclenchement Dm représenté à la Fig. 8 comprend des masselottes 540 avantageusement au nombre de deux, montées chacune à pivotement au niveau d'une de ses extrémités par l'intermédiaire d'un pivot 541 sur le flasque 500 du galet de guidage 50a, de part et d'autre du système de roulement 52a. Les masselottes 540 sont liées entre elles par leurs secondes extrémités au moyen d'un ressort de traction 542. Le système de déclenchement Dm comporte également des picots ou lanternes 671 représentés en pointillés et fixés sur l'organe de freinage 67a (non représenté) uniformément répartis de manière angulaire autour de l'arbre 51a. Ces lanternes 671 sont parallèles à l'axe de l'arbre 51a du galet 50a et encerclent en quelque sorte les masselottes 540.The triggering system Dm represented at Fig. 8 comprises flyweights 540 advantageously two in number, each pivotally mounted at one of its ends by means of a pivot 541 on the flange 500 of the guide roller 50a, on either side of the bearing 52a. The weights 540 are interconnected by their second ends by means of a tension spring 542. The trigger system Dm also comprises pins or lanterns 671 shown in dashed lines and fixed on the braking member 67a (not shown) uniformly. angularly distributed around the shaft 51a. These lanterns 671 are parallel to the axis of the shaft 51a of the roller 50a and encircle somehow the weights 540.

On a représenté à la Fig. 9 une vue de dessus de la partie droite du parachute-guide 2 tel que monté dans le socle 4 (non représenté). Sur cette Fig., on remarque que les masselottes 540 sont fixées sur le galet de guidage droit 50a à l'aide de pivots 541. On remarque également que les lanternes 671 fixées à l'organe de freinage 67a ressortent dans le galet de guidage 50a autour des masselottes 540.We have shown Fig. 9 a top view of the right portion of the guide parachute 2 as mounted in the base 4 (not shown). In this Fig., We note that the weights 540 are fixed on the right guide roller 50a with the help of pivots 541. We also note that the lanterns 671 fixed to the braking member 67a emerge in the guide roller 50a around the 540 weights.

Lors du déplacement de la cabine 1, le galet de guidage droit 50a tourne autour de son arbre 51a et entraîne en rotation autour de l'arbre 51a les masselottes 540 par l'intermédiaire des pivots 541 qui y sont fixés. Les masselottes 540 sont alors soumises à une force centrifuge qui tend à les écarter l'une de l'autre et de l'arbre 51a. Elles sont rappelées dans ce mouvement par le ressort de traction 542. On comprendra donc que plus la vitesse de rotation du galet 50a est importante, plus les masselottes 540 sont éloignées l'une de l'autre et de l'arbre 51a.During the displacement of the cabin 1, the right guide roller 50a rotates about its shaft 51a and drives in rotation around the shaft 51a the weights 540 by means of the pivots 541 which are fixed thereto. The weights 540 are then subjected to a centrifugal force which tends to separate them from each other and the shaft 51a. They are recalled in this movement by the tension spring 542. It will therefore be understood that the greater the rotational speed of the roller 50a, the more the weights 540 are moved away from each other and from the shaft 51a.

Lorsque la vitesse de rotation du galet 50a atteint un seuil de vitesse prédéterminé, la masselotte 540 qui tend le plus à se rapprocher des lanternes 671 en suivant le sens de rotation du galet 50a, pénètre entre deux lanternes 671. Continuant sa rotation, la masselotte 540 pénétrée entre deux lanternes 671, prend appui sur une des lanternes 671 entre lesquelles elle se trouve et entraîne ainsi dans son mouvement de rotation l'organe de freinage 67a. L'organe de freinage 67a pivote et coince un de ses patins sur l'âme 3a du guide 3. Dans l'exemple représenté à la Fig. 8, ce sera la masselotte 540 la plus proche du guide 3 qui assurera le blocage lors d'une prise de vitesse excessive de la cabine 1 en descente, et à l'inverse, ce sera la masselotte 540 la plus éloignée du guide 3 qui assurera le blocage lors d'une prise de vitesse excessive de la cabine 1 en montée.When the rotational speed of the roller 50a reaches a predetermined speed threshold, the weight 540 which tends most to approach the lanterns 671 in the direction of rotation of the roller 50a, enters between two lanterns 671. Continuing its rotation, the flyweight 540 penetrated between two lanterns 671, is supported on one of the lanterns 671 between which it is and thus causes in its rotational movement the braking member 67a. The braking member 67a pivots and jams one of its pads on the web 3a of the guide 3. In the example shown in FIG. Fig. 8 it will be the 540 flyweight closest to the guide 3 which will ensure the blocking during an excessive acceleration of the cabin 1 downhill, and conversely, it will be the flyweight 540 furthest from the guide 3 which will ensure blocking during an excessive speeding up of the car 1 when climbing.

On notera que l'organe de freinage 67a pivote dans le sens qui correspond au sens de rotation du galet 50a. Ainsi, on peut constater que lorsque la cabine 1 monte, c'est le patin haut 670a qui vient se coincer dans l'âme 3a du guide 3, alors que lorsque la cabine 1 descend, c'est le patin bas 670b.Note that the braking member 67a pivots in the direction corresponding to the direction of rotation of the roller 50a. Thus, it can be seen that when the cabin 1 rises, it is the upper skate 670a which is jammed in the core 3a of the guide 3, whereas when the cabin 1 goes down, it is the lower skate 670b.

On constatera également que c'est la constante de raideur du ressort de traction 542 qui fixe le seuil au-delà duquel le système de déclenchement Dm déclenche l'organe de freinage 67a.It will also be noted that it is the stiffness constant of the tension spring 542 which sets the threshold beyond which the triggering system Dm triggers the braking member 67a.

Les systèmes de déclenchement De et Dm respectivement décrits en relation avec les Figs. 4 à 7 et en relation avec les Figs. 8 et 9 peuvent cohabiter sur le même parachute-guide 2. Ces systèmes de déclenchement peuvent être conçus pour commander l'organe de freinage 67a au-delà de seuils de vitesse prédéterminés approximativement identiques. Ils peuvent également être prévus pour que le système de déclenchement mécanique Dm puisse contrecarrer les pannes éventuelles du système de déclenchement électronique De et réciproquement.The triggering systems De and Dm respectively described in connection with the Figs. 4 to 7 and in relation to Figs. 8 and 9 These trigger systems may be designed to control the braking member 67a beyond approximately identical predetermined speed thresholds. They can also be provided so that the mechanical triggering system Dm can counteract the possible failures of the electronic trigger system De and vice versa.

On notera encore que l'actionnement de l'organe de freinage 67a dépend de l'appui des galets 50a, 50b sur l'âme 3a du guide 3. Or, il pourrait arriver qu'un des galets 50a et 50b ou les deux glissent sur le guide 3 au lieu de tourner. Pour parer à ce problème éventuel, l'invention prévoit donc de placer un système de parachute-guide de chaque côté de la cabine 1.Note also that the actuation of the braking member 67a depends on the support of the rollers 50a, 50b on the core 3a of the guide 3. Now, it could happen that one of the rollers 50a and 50b or both slip on guide 3 instead of turning. To counter this potential problem, the invention therefore provides for placing a parachute-guide system on each side of the cabin 1.
