Description

La présente invention concerne le domaine des installations d'ascenseur destinées à être montées dans des bâtiments ou édifices, à l'intérieur ou à l'extérieur de ces derniers, et a pour objet une installation d'ascenseur de faible encombrement.The present invention relates to the field of elevator installations intended to be mounted in buildings or buildings, inside or outside thereof, and relates to a small elevator installation.

On sait qu'un ascenseur est un appareil qui permet d'assurer le déplacement de personnes ou d'objets en hauteur en desservant des niveaux définis ou étages à l'aide d'une cabine qui se déplace dans une gaine verticale disposée à l'intérieur ou à l'extérieur d'un bâtiment ou d'un édifice.It is known that an elevator is a device that makes it possible to move people or objects in height by serving defined levels or floors by means of a cabin that moves in a vertical duct arranged at the inside or outside a building or building.

Une installation d'ascenseur comprend généralement une gaine d'ascenseur verticale avec des parois de gaine, un plafond de gaine et un fond de gaine, une cabine d'ascenseur supportée par une structure d'arcade ou d'étrier guidée en déplacement vertical dans la gaine par des guides de cabine, un moteur d'entraînement, tel qu'un moteur électrique à aimant permanent, qui actionne une poulie motrice entraînant par adhérence au moins un organe allongé de suspente, du type câble, courroie ou chaîne, auquel est suspendu l'arcade et un contrepoids. Ce dernier a pour fonction de permettre notamment de contrebalancer et d'équilibrer la charge de la cabine, d'augmenter l'adhérence des câbles sur la poulie motrice ou encore de réduire la puissance nécessaire pour entraîner la cabine en déplacement dans la gaine.An elevator installation generally comprises a vertical elevator shaft with sheath walls, a shaft ceiling and a shaft bottom, an elevator car supported by a vertical arcade or stirrup structure guided in vertical motion. the sheath by cab guides, a drive motor, such as a permanent magnet electric motor, which actuates a driving pulley driving by adhesion at least one elongated member of hanger, cable, belt or chain type, which is hanging the arch and a counterweight. The latter has the function to allow in particular to counterbalance and balance the load of the cab, to increase the adhesion of the cables on the drive pulley or reduce the power required to drive the cabin moving in the sheath.

Les guides cabines sont généralement constitué par deux rails de guidage, ou autres segments de guidage rigides, formant un plan de guidage s'étendant sensiblement verticalement le long de la course de la cabine, la cabine coulissant alors verticalement entre lesdits rails grâce à des coulisseaux solidaires de la structure d'arcade et venant chacun en appui de coulissement sur la face interne ou externe desdits rails de guidage. Le contrepoids, quant à lui, est guidé par des guides de contrepoids consistant usuellement en deux rails de guidage, entre lesquels se déplace le contrepoids, s'étendant verticalement dans un plan généralement sensiblement parallèle ou perpendiculaire au plan de guidage de la cabine.Cabin guides are generally constituted by two guide rails, or other rigid guide segments, forming a guide plane extending substantially vertically along the stroke of the cabin, the cabin then sliding vertically between said rails with slides integral with the arch structure and each sliding support on the inner or outer face of said guide rails. The counterweight, meanwhile, is guided by counterweight guides usually consisting of two guide rails, between which moves the counterweight, extending vertically in a plane generally substantially parallel or perpendicular to the guide plane of the cabin.

Dans de nombreux immeubles actuels, le moteur est placé dans la partie haute de la gaine, en dehors du système de glisse de la cabine et du contrepoids, dans un local ou une salle machine situé(e) au dessus de la gaine et du dernier étage, notamment à l'extérieur de l'immeuble.In many current buildings, the engine is located in the upper part of the shaft, apart from the sliding system of the cabin and the counterweight, in a room or a machine room located (e) above the sheath and the last floor, especially outside the building.

Or, les architectes demandent aujourd'hui à ce que les installations d'ascenseurs ne prévoient plus de local machine ou autre édicule disposé au sommet et à l'extérieur d'un immeuble ou édifice, ce notamment du fait de leur côté inesthétique et de la nécessité de créer un accès spécifique.However, today's architects are demanding that elevator installations no longer include any machine room or other building located at the top and outside of a building or building, particularly because of their unsightly appearance and their the need to create specific access.

Pour répondre à cette demande, les constructeurs d'ascenseurs ont donc proposé d'installer le local machine dans la gaine de l'ascenseur, en partie basse ou haute de cette dernière.To meet this demand, the elevator manufacturers have proposed to install the machine room in the elevator shaft, in the lower or upper part of the elevator.

Toutefois, les contraintes architecturales actuelles exigent des dimensions de gaines de plus en plus réduites et donc un encombrement réduit de l'installation d'ascenseur et notamment des organes moteurs et leurs accessoires et des systèmes de guidage de la cabine et du contrepoids.However, the current architectural constraints require duct dimensions increasingly reduced and therefore a small footprint of the elevator installation and in particular the drive members and their accessories and guide systems of the cabin and the counterweight.

Pour remédier à ce problème, les constructeurs ont proposé des installations d'ascenseur sans local ou salle machine et ont mis au point des installations d'ascenseur visant à réduire au maximum son encombrement. C'est ainsi qu'il a été proposé que les organe allongé de suspente soient entraînés par l'intermédiaire de poulies de mouflage, fixées sur la cabine ou sur l'arcade et/ou sur le contrepoids, permettant de diviser la charge et d'utiliser un moteur et une poulie motrice de plus petites dimensions.To address this problem, the manufacturers have proposed elevator installations without room or machine room and have developed elevator installations to minimize its bulk. Thus it has been proposed that the elongated hanger member are driven via halyard pulleys, fixed on the cab or on the yoke and / or on the counterweight, to divide the load and d use a motor and a drive pulley of smaller dimensions.

Cependant ces poulies de mouflage augmentent les temps de montage et de maintenance et leur rotation rapide gérière, d'une part, des vibrations et, d'autre part, une usure importante desdites poulies de mouflage et des organes allongés de suspente qu'elles reçoivent. En outre, ces poulies de mouflage, notamment un nombre élevé de poulies de mouflage, diminuent sensiblement le rendement de l'installation et génèrent un encombrement supplémentaire dans la gaine allant à l'encontre des demandes actuelles de diminution de l'encombrement des installations d'ascenseur.However, these haulage sheaves increase the assembly and maintenance time and their rapid rotation handles, on the one hand, vibrations and, on the other hand, significant wear of said hauling pulleys and elongated hanger members they receive . In addition, these hauling pulleys, in particular a high number of hauling pulleys, significantly reduce the efficiency of the installation and generate additional space in the duct going against the current demands for reducing the bulk of the installations. 'elevator.

Il en est de même pour les organes allongés de suspente qui s'usent et se détériorent plus vite lorsqu'ils passent sur des poulies de petites dimensions avec rotation rapide, notamment sur une multiplicité de poulies de petites dimensions telles que des poulies de mouflage.It is the same for the elongated suspension members which wear and deteriorate faster when they pass on small pulleys with rapid rotation, especially on a multiplicity of small pulleys such as pulleys hauling.

En outre, dans le cas où le moteur est disposé en partie haute de la gaine, celui-ci engendre des nuisances sonores pour les appartements situés en étages élevés et l'opérateur qui intervient dans la partie basse de la gaine pour l'entretien et la maintenance de l'ascenseur ne voit pas le moteur qui est caché par la cabine. D'autre part, l'installation d'un moteur et de ses accessoires en partie haute de la gaine est longue et peu aisée et les interventions de maintenance sont contraignantes pour l'opérateur qui ne peut accéder facilement au moteur et en toute sécurité.In addition, in the case where the engine is disposed in the upper part of the sheath, it causes noise pollution for apartments on high floors and the operator who intervenes in the lower part of the sheath for maintenance and maintenance of the elevator does not see the engine that is hidden by the cabin. On the other hand, the installation of a motor and its accessories in the upper part of the sheath is long and not easy and maintenance interventions are binding for the operator who can easily access the engine and safely.

En outre, dans les installations actuelles, l'accessibilité au moteur du toit d'une cabine ou de l'intérieur de cette dernière par une trappe du toit, ne permet pas d'observer ledit moteur et ses accessoires en fonctionnement.In addition, in current installations, accessibility to the engine roof of a cabin or inside the latter by a roof hatch, does not allow to observe said engine and its accessories in operation.

Dans le cas où le moteur est situé en partie basse de la gaine, celui-ci est exposé aux risques d'inondations, notamment lorsqu'il est placé dans une cuvette formant une partie de la gaine s'étendant sensiblement du seuil inférieur de la course de la cabine jusqu'au fond de gaine.In the case where the engine is located in the lower part of the sheath, it is exposed to the risk of flooding, especially when it is placed in a bowl forming a portion of the sheath extending substantially from the lower threshold of the race from the cabin to the bottom of the shaft.

Enfin, le placement du moteur d'entraînement dans la gaine, en partie haute ou en partie basse de la gaine présente un risque pour l'opérateur de maintenance qui peut être écrasé par la cabine lors d'une remontée ou d'une descente anormale de la cabine selon que l'opérateur intervient dans la partie supérieure ou inférieure de la gaine.Finally, the placement of the drive motor in the sheath, in the upper part or in the lower part of the sheath presents a risk for the maintenance operator who can be crushed by the cabin during an ascent or descent abnormal of the cab depending on whether the operator intervenes in the upper or lower part of the sheath.

Le document US 6 397 975 B1 a pour objet une installation d'ascenseur comprenant une cabine supportée par une structure d'arcade, une gaine d'ascenseur délimitée par quatre parois de gaine, à savoir une paroi arrière, une paroi avant, une paroi latérale gauche et une paroi latérale droite venant d'équerre avec lesdites parois arrière et avant, un ensemble de guidage, situé entre la paroi latéral droite et la cabine, comportant des rails de guidage verticaux permettant de guider en translation verticale un contrepoids et la structure d'arcade de la cabine et un système de poulies de renvoi fixé latéralement en partie haute de la gaine sur lesdits rails de guidage.

Les figures montrent une installation d'ascenseur de faible encombrement destinée à être montée dans un bâtiment ou un édifice, à l'intérieur ou l'extérieur de ces derniers, comprenant une gaine 1 d'ascenseur délimitée par des parois de gaine 2 verticales, un fond de gaine 3 et un plafond de gaine 4, une cabine 5 d'ascenseur supportée par une structure d'arcade 6 guidée par des guides de cabine 7, du type rails de guidage ou segments analogues, un moteur d'entraînement 8 actionnant une poulie motrice 9 entraînant au moins un organe allongé de suspente 10 permettant de déplacer verticalement dans la gaine 1 ladite structure d'arcade 6 et un contrepoids 11 guidé par des guides de contrepoids 12, lesdits guides de cabine 7 et lesdits guides de contrepoids 12 formant un ensemble de guidage 7, 12.The figures show a small elevator installation intended to be mounted in a building or a building, inside or outside thereof, comprising an elevator shaft 1 delimited by vertical duct walls 2, a duct bottom 3 and a duct ceiling 4, an elevator car 5 supported by an arcade structure 6 guided by car guides 7, of the guide rails type or similar segments, a driving motor 8 actuating a driving pulley 9 driving at least one elongate member of the hanger 10 for vertically moving in the sheath 1 said arch structure 6 and a counterweight 11 guided by counterweight guides 12, said cabin guides 7 and said counterweight guides 12 forming a guide assembly 7, 12.

Conformément à la présente invention, dans une telle installation :

  • l'ensemble de guidage 7, 12 s'étend, le long de la course de la cabine 5, entre l'une des parois de gaine 2, dite paroi de gaine principale 2.1, et ladite cabine 5,
  • le moteur d'entraînement 8 est encastré dans l'une des parois de gaine 2.1, et
  • la poulie motrice 9 est disposée fonctionnellement dans l'espace interne de la gaine 1, entre ladite paroi de gaine principale 2.1 et l'ensemble de guidage 7, 12, l'axe d'entraînement 9' en rotation de ladite poulie motrice 9 s'étendant sensiblement perpendiculairement à ladite paroi de gaine principale 2.1.
According to the present invention, in such an installation:
  • the guide assembly 7, 12 extends, along the course of the car 5, between one of the sheath walls 2, called the main duct wall 2.1, and said cabin 5,
  • the drive motor 8 is embedded in one of the duct walls 2.1, and
  • the driving pulley 9 is functionally arranged in the internal space of the sheath 1, between said main cladding wall 2.1 and the guide assembly 7, 12, the drive shaft 9 'in rotation of said driving pulley 9 s extending substantially perpendicular to said main duct wall 2.1.

En outre, toujours conformément à la présente invention une telle installation comprend un système de poulies de renvoie 13, 14, 15, 15' fixe, coopérant éventuellement avec au moins une poulie de déflexion fixe 16, susceptible de permettre à la poulie motrice 9 d'assurer un entraînement direct de la structure d'arcade 6 et du contrepoids 11.In addition, still in accordance with the present invention such an installation comprises a system of fixed return pulleys 13, 14, 15, 15 ', possibly cooperating with at least one fixed deflection pulley 16, capable of enabling the driving pulley 9 d ensure a direct drive of the arch structure 6 and the counterweight 11.

On entendra par entraînement direct de la cabine 5 et du contrepoids 11, un entraînement sans mouflage.Direct drive of the cab 5 and the counterweight 11 will be understood to mean a drive without hauling.

On entendra par moteur d'entraînement 8, comme on peut le voir sur les figures 1, 2 et 5, le moteur en tant que tel et son châssis.It will be understood by drive motor 8, as can be seen on the figures 1 , 2 and 5 , the engine as such and its chassis.

Si on se réfère maintenant aux figures 1, 2 et 5, on peut voir que le moteur d'entraînement 8 peut être encastré dans la paroi de gaine principale 2.1 en étant logé avec serrage et blocage en position de fonctionnement dans un logement de réception 8' pratiqué dans la paroi de gaine principale 2.1, traversant éventuellement ladite paroi. De préférence un tel moteur d'entraînement 8, sous entendu le châssis du moteur en tant que tel, peut être serré et maintenu avec blocage dans le logement de réception 8' par l'intermédiaire d'une ou plusieurs pièces 8" permettant d'absorber des vibrations et des chocs, chaque pièce 8" pouvant être du type connu sous la marque déposée « silentbloc » ou analogue.If we now turn to figures 1 , 2 and 5 it can be seen that the drive motor 8 can be embedded in the main duct wall 2.1 while being housed with clamping and locking in the operating position in a receiving housing 8 'formed in the main duct wall 2.1, possibly traversing said wall. Preferably, such a drive motor 8, under the chassis of the motor as such, can be clamped and held in the receiving housing 8 'by means of one or more parts 8 "allowing absorbing vibrations and shocks, each piece 8 "may be of the type known under the trademark" silentbloc "or the like.

Dans un mode de réalisation préférentiel de la gaine 1, celle-ci peut se terminer à sa partie basse par une cuvette 17 formant une partie de la gaine 1 s'étendant sensiblement du seuil inférieur de la course de la cabine 5 jusqu'au fond de gaine 3 et le moteur d'entraînement 8 peut être positionné en partie basse de la gaine 1 dans ladite cuvette 17 ou sensiblement au-dessus de cette dernière (figures 1, 2 et 5).In a preferred embodiment of the sheath 1, it may end at its lower part by a bowl 17 forming a portion of the sheath 1 extending substantially from the lower threshold of the stroke of the cabin 5 to the bottom 3 and the drive motor 8 can be positioned in the lower part of the sheath 1 in said bowl 17 or substantially above the latter ( figures 1 , 2 and 5 ).

Ainsi, la position du moteur d'entraînement 8 au dessus du fond de gaine, à distance de ce dernier et plus particulièrement au dessus de la cuvette 17 permet d'éviter, lors d'une présence anormale d'eau dans la cuvette 17, tout risque de détérioration dudit moteur 8.Thus, the position of the drive motor 8 above the bottom of the sheath, at a distance from the latter and more particularly above the bowl 17 makes it possible to avoid, during an abnormal presence of water in the bowl 17, any risk of deterioration of the engine 8.

En outre, la position du moteur d'entraînement 8 en partie basse de la gaine 1, notamment sensiblement au-dessus de la cuvette 17 et, de préférence, sous le seuil inférieur de la course de la cabine 5, permet à un opérateur intervenant dans la partie basse de la gaine 1, notamment dans la cuvette 17, de pouvoir observer en toute sécurité à la fois le fonctionnement du moteur d'entraînement 8 et la poulie motrice 9 et d'autres organes de l'installation d'ascenseur. Ces derniers peuvent être, par exemple, le système de frein parachute, non représenté, disposé sous la cabine 5 et consistant usuellement en un étrier venant se presser sur un rail de guidage 7 de la cabine 5 en cas d'accélération anormale de cette dernière, ou encore les coulisseaux 19 fixés généralement sous le système de frein parachute à chaque coin inférieur concerné de la structure d'arcade 6, assurant le glissement de la cabine 5 sur les guides de cabine 7 (figure 2).In addition, the position of the drive motor 8 in the lower part of the sheath 1, in particular substantially above the cup 17 and, preferably, below the lower threshold of the stroke of the booth 5, allows an operator to intervene in the lower part of the sheath 1, in particular in the bowl 17, to be able to observe both the operation of the drive motor 8 and the drive pulley 9 and other members of the elevator installation safely. These may be, for example, the parachute brake system, not shown, disposed under the cab 5 and usually consisting of a stirrup coming to press on a guide rail 7 of the cabin 5 in case of abnormal acceleration of the latter , or the slides 19 generally fixed under the brake system parachute at each lower corner concerned of the arch structure 6, ensuring the sliding of the cabin 5 on the car guides 7 ( figure 2 ).

Dans un mode de réalisation préférentiel du système de poulies de renvoie 13, 14, 15, 15' celui-ci peut comprendre une première poulie de renvoie 13 assurant l'entraînement direct de la structure d'arcade 6 supportant la cabine 5, une seconde poulie de renvoie 14 assurant l'entraînement direct du contrepoids 11 et une charpente de poulies 15, 15' apte à supporter les première et seconde poulies 13 et 14 (figures 1, 2, 4 et 5).In a preferred embodiment of the system of return pulleys 13, 14, 15, 15 'it may comprise a first pulley of returns 13 providing direct drive of the arch structure 6 supporting the cabin 5, a second return pulley 14 providing direct drive of the counterweight 11 and a pulley frame 15, 15 'adapted to support the first and second pulleys 13 and 14 ( figures 1 , 2 , 4 and 5 ).

De préférence, la première poulie de renvoie 13 et la seconde poulie de renvoie 14 peuvent être orientées sensiblement perpendiculairement l'une par rapport à l'autre. En outre, la charpente de poulies peut être constitué par deux traverses 15, 15', sensiblement parallèles entre elles, fixées sensiblement horizontalement et de façon oblique à la paroi de gaine principale 2.1 et à l'une des autres parois de gaine 2 adjacente à cette dernière, la première poulie de renvoie 13 pouvant être orientée sensiblement perpendiculairement auxdites traverses 15, 15', tandis que la seconde poulie 14 peut être orientée sensiblement parallèlement auxdites traverses 15, 15'. D'autre part, de préférence, la seconde poulie de renvoie 14 peut être fixée entre les deux traverses 15, 15' de sorte que les organes allongés de suspente 10 passent entre lesdites traverses 15, 15' et la première poulie de renvoie 13 peut être fixée transversalement sur les traverses 15, 15' en surplombant ces dernières de sorte que les organes allongés de suspente 10 passent de part et d'autre de l'ensemble desdites traverses 15, 15'.Preferably, the first return pulley 13 and the second return pulley 14 may be oriented substantially perpendicularly with respect to each other. In addition, the pulley frame may consist of two crosspieces 15, 15 ', substantially parallel to each other, fixed substantially horizontally and obliquely to the main cladding wall 2.1 and to one of the other sheath walls 2 adjacent to the latter, the first return pulley 13 can be oriented substantially perpendicular to said cross members 15, 15 ', while the second pulley 14 can be oriented substantially parallel to said cross members 15, 15'. On the other hand, preferably, the second return pulley 14 can be fixed between the two crosspieces 15, 15 'so that the elongate hanger members 10 pass between said crosspieces 15, 15' and the first return pulley 13 can to be fixed transversely on the crosspieces 15, 15 'overhanging the latter so that the elongated members of the hanger 10 pass on either side of all of said cross members 15, 15'.

De préférence, une partie d'extrémité de la charpente de poulies 15, 15' peut être logée dans un logement de réception 2' pratiqué dans la partie supérieure correspondante de la paroi de gaine principale 2.1 et peut être disposée dans ledit logement 2' par l'intermédiaire d'une ou plusieurs pièces du type connu sous la marque déposée « silentbloc » ou analogues, comme on peut le voir sur la figure 1 et sur la figure 4. Plus particulièrement, la présente invention peut prévoir que la traverse 15 de la charpente de poulie 15, 15' la plus proche de la paroi de gaine principale 2.1 soit fixée sur cette dernière par l'une de ses extrémités libres venant se fixer dans le logement de réception 2' de ladite gaine principale 2.1 et que l'une des extrémités libres de l'autre traverse 15' vienne se fixer sur l'un des guides de cabine 7 situé à proximité dudit logement de réception 2' ou sur l'une des pièces d'attache 20 permettant la fixation du guide de cabine 7 sur la paroi de gaine principale 2.1.Preferably, an end portion of the pulley frame 15, 15 'can be housed in a receiving housing 2' formed in the corresponding upper part of the main cladding wall 2.1 and can be disposed in said housing 2 'by through one or more pieces of the type known under the trademark "silentbloc" or the like, as can be seen on the figure 1 and on the figure 4 . More particularly, the present invention may provide that the crosspiece 15 of the pulley frame 15, 15 'closest to the main sheath wall 2.1 is fixed on the latter by one of its free ends coming to fix in the housing 2 'of said main sheath 2.1 and that one of the free ends of the other cross member 15' attaches to one of the car guides 7 located near said receiving housing 2 'or on one fasteners 20 for attaching the car guide 7 to the main cladding wall 2.1.

D'autre part, la présente invention peut prévoir un chevauchement, de préférence un léger chevauchement, entre la première poulie 13 et la seconde poulie 14 situées l'une au dessus de l'autre et avec un décalage horizontale entre ces dernières. De préférence, l'un des brins reliant la seconde poulie 14 au contrepoids peut venir sensiblement à l'aplomb de la première face latérale de la première poulie 13.On the other hand, the present invention may provide for an overlap, preferably a slight overlap, between the first pulley 13 and second pulley 14 located one above the other and with a horizontal offset therebetween. Preferably, one of the strands connecting the second pulley 14 to the counterweight may come substantially in line with the first lateral face of the first pulley 13.

La présente invention peut comprendre en outre une poulie de déflexion 16 de chaque organe allongé de suspente 10 qui peut être disposée fonctionnellement dans l'espace interne de la gaine 1, entre la paroi de gaine principale 2.1 logeant le moteur d'entraînement 8 et l'ensemble de guidage 7, 12. L'axe d'entraînement 16' en rotation de ladite poulie de déflexion 16 peut s'étendre de préférence sensiblement perpendiculairement à la paroi de gaine principale 2.1 et la poulie de déflexion 16 peut être située préférentiellement à proximité de la poulie motrice 9, en recevant le ou chaque organe allongé de suspente 10 soit entre ladite poulie motrice 9 et la première poulie de renvoie 13 assurant l'entraînement direct de la structure d'arcade 6 (figures 1 et 2), soit entre ladite poulie motrice 9 et la seconde de poulie de renvoie 14 assurant l'entraînement direct du contrepoids 11.The present invention may further comprise a deflection pulley 16 of each elongate hanger member 10 which may be operatively disposed in the inner space of the sheath 1, between the main cladding wall 2.1 housing the drive motor 8 and the Guiding assembly 7, 12. The drive shaft 16 'in rotation of said deflection pulley 16 may extend preferably substantially perpendicular to the main cladding wall 2.1 and the deflection pulley 16 may be preferably located at near the driving pulley 9, receiving the or each elongated member of the hanger 10 between said driving pulley 9 and the first return pulley 13 providing direct drive of the arch structure 6 ( figures 1 and 2 ), or between said drive pulley 9 and the second return pulley 14 providing direct drive of the counterweight 11.

On comprendra que lorsque le brin du ou de chaque organe allongé de suspente 10 reliant la poulie motrice 9 à la seconde poulie de renvoie 14, respectivement à la première poulie de renvoie 13, s'étend verticalement entre ces dernières et que le brin du ou de chaque organe allongé de suspente 10 reliant la poulie motrice 9 à la première poulie de renvoie 13, respectivement la seconde poulie de renvoie 14, est incliné par rapport à un axe vertical, une correction angulaire doit être effectuée pour amener le brin incliné concerné dans un axe sensiblement vertical, ce afin d'éviter tout décrochage du ou de chaque organe allongé de suspente 10, du fait de son inclinaison, de la poulie de renvoie 13 ou 14 correspondante.It will be understood that when the strand of the or each elongated member of hanger 10 connecting the driving pulley 9 to the second return pulley 14, respectively to the first return pulley 13, extends vertically between them and that the strand of the of each elongate hanger member 10 connecting the drive pulley 9 to the first return pulley 13, respectively the second return pulley 14, is inclined with respect to a vertical axis, an angular correction must be made to bring the inclined strand concerned into a substantially vertical axis, in order to prevent any stall of the or each elongated member of the hanger 10, because of its inclination, the corresponding return pulley 13 or 14.

C'est le rôle d'une telle poulie de déflexion 16 qui permet alors d'amener le brin incliné concerné du ou de chaque organe allongé de suspente 10 dans un axe sensiblement vertical entre la poulie motrice 9 et la poulie de renvoie 13 ou 14 correspondante, tangentiellement à ces dernières.It is the role of such a deflection pulley 16 which then makes it possible to bring the inclined strand concerned of the or each elongate member of the hanger 10 in a substantially vertical axis between the driving pulley 9 and the return pulley 13 or 14 corresponding, tangentially to the latter.

Par ailleurs, la poulie de déflexion 16 peut être fixée sur les guides de cabines 7 et/ou sur les guides de contrepoids 12 et/ou sur la paroi de gaine principale 2.1.Furthermore, the deflection pulley 16 can be fixed on the cab guides 7 and / or on the counterweight guides 12 and / or on the main cladding wall 2.1.

De préférence, dans une variante, non représentée, la poulie de déflexion 16 peut être fixée sur le moteur d'entraînement 8, sous entendu sur le châssis du moteur en tant que tel, par exemple par l'intermédiaire d'une pièce de fixation en U dont l'une des ailes peut être fixée sur la face supérieure du moteur d'entraînement 8 et l'autre sur la poulie de déflexion 16. Ainsi, lorsque le moteur d'entraînement 8 est maintenu avantageusement dans le logement 8' par l'intermédiaire des pièces 8" ou « silentblocs » absorbant les vibrations, la poulie de déflexion 16, fixée sur le moteur d'entraînement 8, peut alors bénéficier également de l'effet d'absorption procuré par lesdites pièces 8" d'absorption de vibrations, ce qui a pour effet de réduire encore le bruit de l'installation selon la présente invention dans le cas où celle-ci comporte une poulie de déflexion 16. En outre le fait de prévoir la fixation de la poulie 16 sur le moteur d'entraînement 8 présente également l'avantage de réduire le nombre de pièces de fixation.Preferably, in a variant, not shown, the deflection pulley 16 can be fixed on the drive motor 8, for example on the chassis of the engine as such, for example by means of a U-shaped fastener one of whose wings can be fixed on the upper face of the drive motor 8 and the other on the pulley 16. Thus, when the drive motor 8 is advantageously maintained in the housing 8 'by means of vibration damping pieces 8 "or" silentblocs ", the deflection pulley 16, fixed on the drive motor 8, can also benefit from the absorption effect provided by said vibration absorbing parts 8 ", which has the effect of further reducing the noise of the installation according to the present invention in the case where the latter comprises a deflection pulley 16. In addition, the fact of providing the attachment of the pulley 16 on the drive motor 8 also has the advantage of reducing the number of fasteners.

Dans un mode de réalisation préférentiel de la structure d'arcade 6, celle-ci peut présenter avantageusement un profil en L, la partie horizontale du L s'étendant sensiblement perpendiculairement à la paroi de gaine principale 2.1 et pouvant constituer un siège de support et d'armature sur laquelle peut reposer la cabine 5 avec maintien et blocage en position, tandis que la partie verticale du L, formant la partie arrière de la structure d'arcade 6 située en regard de la paroi de gaine principale 2.1, peut comporter un espace de glissement 6' apte à recevoir une partie ou la totalité de l'ensemble de guidage 7, 12, du contrepoids 11 et des organes allongés de suspente 10 qui traversent alors verticalement la partie arrière de ladite structure d'arcade 6 située en regard de la paroi de gaine principale 2.1, comme on peut le voir notamment sur la figure 1 et sur la figure 3.In a preferred embodiment of the arch structure 6, it can advantageously have an L-shaped profile, the horizontal portion of the L extending substantially perpendicular to the main cladding wall 2.1 and which can constitute a support seat and of armature on which can rest the cabin 5 with holding and locking position, while the vertical portion of the L, forming the rear portion of the arcade structure 6 located opposite the main duct wall 2.1, may comprise a sliding space 6 'able to receive part or all of the guiding assembly 7, 12, the counterweight 11 and the elongate hanger members 10 which then traverse vertically the rear portion of said arcade structure 6 located opposite of the main cladding wall 2.1, as can be seen in particular on the figure 1 and on the figure 3 .

La structure d'arcade 6 peut comprendre en outre une traverse supérieure 18 d'attache ou d'accrochage s'étendant sensiblement parallèlement à la paroi de gaine principale 2.1 au dessus de la cabine 5 et en avant de l'ensemble de guidage 7, 12 situé entre ladite traverse supérieure 18 et la paroi de gaine principale 2.1. Le ou chaque organe allongé de suspente 10 peut alors être fixé en un point d'attache ou d'accrochage 18' sur la traverse supérieure 18.The arch structure 6 may furthermore comprise an upper fastening or hooking cross-member 18 extending substantially parallel to the main cladding wall 2.1 above the car 5 and in front of the guiding assembly 7. 12 located between said upper cross member 18 and the main cladding wall 2.1. The or each elongated member of hanger 10 can then be fixed at a point of attachment or attachment 18 'on the upper rail 18.

De préférence le siège de la structure d'arcade 6 peut être constitué par deux fourches 6" s'étendant sensiblement horizontalement dans la gaine 1, écartées l'une de l'autre de façon appropriée et formant chacune la base d'une pièce ou partie de support et d'armature latérale en L, lesdites pièces étant reliées ensemble rigidement par au moins un élément de renfort transversal 6"'.Preferably the seat of the arch structure 6 can be constituted by two forks 6 "extending substantially horizontally in the sheath 1, spaced from each other appropriately and each forming the base of a room or support part and L-shaped side frame, said parts being rigidly connected together by at least one transverse reinforcement element 6 "'.

La traverse supérieure 18 peut être fixée dans la structure d'arcade en reliant fixement les parties supérieures des deux branches verticales des pièces de support et d'armature latérales en L. En outre, les branches verticales peuvent délimiter avantageusement entre elles un espace constituant l'espace de glissement 6' apte à recevoir une partie ou, de préférence, la totalité de l'ensemble de guidage 7, 12, du contrepoids 11 et des organes allongés de suspente 10.The upper crossmember 18 can be fixed in the arch structure by fixedly connecting the upper parts of the two vertical branches of the L-shaped supporting and reinforcing parts. In addition, the vertical branches can advantageously delimit between them a space constituting the sliding space 6 'able to receive a portion or, preferably, the whole of the guiding assembly 7, 12, the counterweight 11 and the elongate hanger members 10.

On peut voir également sur la figure 2 que les guides de cabines 7 sont situés entre les deux fourches de levage 6" et que chaque fourche de levage 6" peut comprendre un ou plusieurs coulisseaux 19, par exemple du type galet de roulement, de préférence en matière plastique pour réduire le bruit, venant en appui de roulement contre la face latérale externe du guide de cabine 7 correspondant (figure 2).We can also see on the figure 2 that the cab guides 7 are situated between the two lifting forks 6 "and that each lifting fork 6" may comprise one or more sliders 19, for example of the rolling roller type, preferably of plastic material for reducing the noise, bearing against the external lateral face of the corresponding cabin guide 7 ( figure 2 ).

On comprendra que le coulissement peut être, par exemple, un coulissement par glissement ou par roulement (galets de roulement).It will be understood that the sliding can be, for example, sliding or rolling (rollers).

Le ou les points d'attache ou d'accrochage 18' peu(ven)t être situé(s) de préférence vers le centre de gravité de l'ensemble cabine 5 et structure d'arcade 6, ce de sorte à dégager la course du contrepoids 11 et pour obtenir une meilleure glisse de la cabine 5 via la structure d'arcade 6, ce grâce à un porte-à-faux réduit.The attachment point (s) 18 'may preferably be located towards the center of gravity of the cabin assembly 5 and the arch structure 6, so as to clear the race counterweight 11 and for better sliding of the cabin 5 via the arch structure 6, thanks to a reduced cantilever.

De préférence, les guides de cabine 7 peuvent consister en deux rails de guidage sur lesquels coulissent les coulisseaux 19 solidaires de la structure d'arcade 6 et les guides de contrepoids peuvent consister également en deux rails de guidage 12, entre lesquels glisse verticalement le contrepoids 11, situés entre les deux rails de guidage 7 de la cabine 5 sensiblement dans le plan contenant ces derniers ou dans un plan parallèle à, préférentiellement à proximité de, ce dernier.Preferably, the car guides 7 may consist of two guide rails on which slide the slides 19 integral with the arch structure 6 and the counterweight guides may also consist of two guide rails 12, between which slides the counterweight vertically 11, located between the two guide rails 7 of the cabin 5 substantially in the plane containing the latter or in a plane parallel to, preferably near, the latter.

D'autre part, les rails de guidage 7 de la cabine 5 et les rails de guidage 12 du contrepoids 11 peuvent être fixés sur la paroi de gaine principale 2.1 au moyen de pièces d'attaches 20, par exemple en forme de profilé ou de platine rigide, ou autre élément de fixation ou d'accrochage.On the other hand, the guide rails 7 of the cab 5 and the guide rails 12 of the counterweight 11 can be fixed to the main cladding wall 2.1 by means of fastener parts 20, for example in the form of a profile or rigid plate, or other fastening or fastening element.

De manière avantageuse la présente invention peut prévoir que les rails de guidage 7 de la cabine 5 et les rails de guidage 12 du contrepoids 11 forment des paires de rails de guidage 7, 12 mixtes composées d'un rail de guidage 7 et d'un rail de guidage 12, chaque paire de rails de guidage 7, 12 étant fixée sur la paroi de gaine principale 2.1 au moyen d'une pièce d'attache 20 commune aux rails de guidage 7, 12 de ladite paire de guidage concernée.Advantageously the present invention can provide that the guide rails 7 of the cabin 5 and the guide rails 12 of the counterweight 11 form pairs of guide rails 7, 12 mixed composed of a guide rail 7 and a guide rail 12, each pair guide rails 7, 12 being fixed to the main cladding wall 2.1 by means of an attachment piece 20 common to the guide rails 7, 12 of said guide pair concerned.

Ainsi, grâce à une installation d'ascenseur selon la présente invention, les guides de cabine 7 et les guides de contrepoids 12 peuvent être avantageusement fixés sur une seule paroi de gaine 2 ou paroi de gaine principale 2.1, laissant les autres parois de gaine 2 libres, permettant l'accès dans la cabine 5 au choix sur l'un ou les autres côtés, ce qui ne peut être obtenu avec les installations actuelles comportant notamment des poulies de mouflage ou de renvoie solidaires de la structure d'arcade 6 et/ou de la cabine 5 et notamment avec l'installation décrite dans le document US 6 397 975 B1 qui nécessite deux parois de gaine et de nombreuses poulies de renvoies pour compenser le décalage ou le désaxage du moteur dans un coin de la gaine.Thus, thanks to an elevator installation according to the present invention, the cab guides 7 and the counterweight guides 12 can advantageously be fixed on a single sheath wall 2 or main sheath wall 2.1, leaving the other sheath walls 2 free, allowing access in the cabin 5 to choose on one or the other sides, which can not be achieved with current facilities including pulleys hauling or returns integral with the arch structure 6 and / or cabin 5 and in particular with the installation described in the document US 6,397,975 B1 which requires two sheath walls and many return pulleys to compensate for shifting or misalignment of the engine in a corner of the sheath.

En outre le fait qu'une partie ou, de préférence, la totalité de l'ensemble de guidage 7, 12, du contrepoids 11 et des organes allongés de suspente 10 peut traverser la structure d'arcade 6, notamment sa partie arrière, plus particulièrement entre les deux pièces de support et d'armature latérales en L de ladite structure d'arcade, permet de faire glisser l'ensemble de guidage 7, 12, le contrepoids 11 et les organes allongés de suspente 10 dans cet encombrement réduit, ce qui a pour effet de réduire d'autant l'espace occupé par l'installation selon la présente invention dans la gaine 1.In addition, the fact that a portion, or preferably all, of the guiding assembly 7, 12, of the counterweight 11 and the elongated hanger members 10 can pass through the arch structure 6, in particular the rear portion thereof, plus particularly between the two L-shaped side support and frame pieces of said yoke structure, makes it possible to slide the guide assembly 7, 12, the counterweight 11 and the elongate hanger members 10 into this reduced bulk, this which has the effect of reducing by the same amount the space occupied by the installation according to the present invention in the sheath 1.

Le moteur d'entraînement 8 d'une installation selon la présente invention qui peut être logé dans l'épaisseur de l'une des parois de gaine 2, à tous les niveaux, sera positionné de préférence en partie basse de la gaine pour deux raisons principales :

  • l'entretien du moteur d'entraînement 8 peut être réalisé en toute sécurité à partir du fond de gaine 3 et, le cas échéant, préférentiellement à partir de la cuvette 17, ceci afin de pouvoir observer, en fonctionnement, par exemple le moteur d'entraînement 8, les organe allongé de suspente 10, le système de freins et les poulies,
  • le moteur d'entraînement 8 est éloigné des pièces d'habitation, et l'orientation de la poulie motrice 9, avec l'encastrement dudit moteur 8 dans l'une des parois de gaine 2, permet d'utiliser une poulie motrice 9 de grandes dimensions, ce sans encombrer l'espace intérieur de la gaine 1, tout en réduisant le niveau sonore par rapport aux installations existantes.
The drive motor 8 of an installation according to the present invention which can be accommodated in the thickness of one of the sheath walls 2, at all levels, will preferably be positioned at the bottom of the sheath for two reasons. Main:
  • the maintenance of the drive motor 8 can be carried out safely from the bottom of the sheath 3 and, where appropriate, preferably from the bowl 17, so as to observe, in operation, for example the motor of the 8, the elongate suspension member 10, the brake system and the pulleys,
  • the driving motor 8 is remote from the living quarters, and the orientation of the driving pulley 9, with the embedding of said motor 8 in one of the sheath walls 2, makes it possible to use a driving pulley 9 of large dimensions, without encumbering the interior space of the duct 1, while reducing the noise level compared to existing installations.

On notera que la présente invention peut prévoir un dispositif électrique de maintenance assurant la non desserte du niveau d'observation le plus bas pour un intervenant située en position debout dans la cuvette 17 afin de protéger ce dernier qui dépasserait de ladite cuvette 17 dans cette position.Note that the present invention may provide an electrical maintenance device ensuring the non-serving the lowest observation level for a speaker standing upright in the bowl 17 to protect the latter protruding from said bowl 17 in this position .

En outre l'entraînement direct de la cabine 5 et du contrepoids 11 sans mouflage permet de diminuer le nombre de poulies et la longueur des organes allongés de suspente 10 et donc le prix de revient de l'installation ainsi que la complexité du montage dans la gaine 1 et partant le temps de montage.In addition, the direct drive of the cab 5 and the counterweight 11 without hauling makes it possible to reduce the number of pulleys and the length of the elongated hanger members 10 and therefore the cost price of the installation as well as the complexity of mounting in the machine. sheath 1 and leaving the assembly time.

D'autre part, le fait que l'installation selon la présente invention ne comporte pas de poulies de mouflage, contrairement aux installations actuelles et notamment les installations où le moteur d'entraînement est disposé dans la partie basse de la gaine 1, permet de prévoir une gaine 1 avec une cuvette de dimensions réduites, tout en répondant aux normes de sécurités.On the other hand, the fact that the installation according to the present invention does not comprise hauling pulleys, unlike current installations and in particular the installations where the drive motor is arranged in the lower part of the sheath 1, makes it possible to provide a sheath 1 with a bowl of small dimensions, while meeting the safety standards.

Par ailleurs, la fixation de l'ensemble de guidage 7, 12 sur une seule paroi de gaine 2 et la possibilité de fixer une paire de guide de cabine 7 et de guide de contrepoids 12 avec des pièces d'attache 20 communes permet, outre le gain de temps au montage, de laisser la possibilité d'établir trois accès à la cabine 5.Furthermore, the fixing of the guiding assembly 7, 12 on a single sheath wall 2 and the possibility of attaching a pair of cab guide 7 and counterweight guide 12 with common fastening parts 20 makes it possible the time saving in the assembly, to leave the possibility to establish three access to the cabin 5.

En outre, le moteur d'entraînement 8 peut être de préférence un moteur électrique et plus particulièrement un moteur synchrone de type plat à aimants permanents.In addition, the drive motor 8 may preferably be an electric motor and more particularly a synchronous motor of flat type permanent magnets.

D'autre part encore, les organes allongés de suspente peuvent être de préférence des câbles à entraînement par poulie traction ou des câbles gainés avec possibilité d'entraînement par friction.On the other hand, the elongated hanger members may be preferably traction sheave cables or sheathed cables with the possibility of friction drive.

Enfin, les rails de guidage 7 et 12 peuvent présenter une section transversale en T et une paire de rails de guidage 7 et 12 peut être composée d'un rail de guidage 7 en T et d'un rail de guidage 12 en T qui peuvent être montés en opposition l'un par rapport à l'autre (figure 3 et figure 4) et être fixés chacun de préférence par la face externe de la base du T sur les pièces d'attache 20 correspondantes (figure 3 et figure 4).Finally, the guide rails 7 and 12 may have a T-shaped cross-section and a pair of guide rails 7 and 12 may be composed of a T-shaped guide rail 7 and a T-shaped guide rail 12 which may to be mounted in opposition to one another ( figure 3 and figure 4 ) and preferably each be fixed by the outer face of the base of the T on the corresponding fasteners 20 ( figure 3 and figure 4 ).

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, especially from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
