Description

L'invention concerne les portes de cabine d'ascenseurs, en particulier pour la transformation des ascenseurs à paroi lisse.The invention relates to elevator car doors, in particular for the transformation of smooth-walled elevators.

On sait que sous certaines conditions, notamment de vitesse réduite, il a été toléré jusqu'ici l'installation d'ascenseurs dits à paroi lisse, caractérisés par l'absence de porte de cabine et l'uti­lisation de simples portes palières du type ouvrant vers l'extérieur, avec ouverture manuelle et fermeture automatique par rappel élasti­que. Les faces intérieures des diverses portes palières affleurent la surface intérieure de la gaine d'ascenseur pour constituer une paroi lisse contre laquelle la cabine se raccorde avec le minimum de jeu par un seuil et des retours d'entrée. Le déverrouillage des portes palières, pour autoriser l'ouverture manuelle, est assuré par des serrures munies d'un levier de manoeuvre à galet actionné par une came fixée sur la cabine. Enfin, des contacts des portes palières vérifient la fermeture de toutes ces portes pour autoriser le dé­placement de la cabine.We know that under certain conditions, in particular at reduced speed, it has been tolerated so far the installation of so-called smooth-wall elevators, characterized by the absence of a car door and the use of simple landing doors of the opening type outwards, with manual opening and automatic closing by elastic return. The interior faces of the various landing doors are flush with the interior surface of the elevator shaft to form a smooth wall against which the car is connected with the minimum clearance by a threshold and input returns. The unlocking of the landing doors, to authorize manual opening, is ensured by locks provided with a roller operating lever actuated by a cam fixed on the cabin. Finally, landing door contacts check that all these doors are closed to allow the car to be moved.

Ce type d'installation présente l'avantage d'être extrêmement économique et très peu encombrant, mais par contre il ne présente pas la sécurité voulue pour les usagers. Pour cette raison, dans la plupart des pays où ce type d'installation était accepté, des dis­positions réglementaires vont rendre obligatoire, à brève échéance, la transformation de toutes les installations existantes de ce type pour les rendre conformes aux normes de sécurité, en particulier par l'adjonction de portes de cabine.This type of installation has the advantage of being extremely economical and very space-saving, but on the other hand it does not offer the desired security for the users. For this reason, in most countries where this type of installation was accepted, regulatory provisions will make it compulsory, in the short term, the transformation of all existing installations of this type to make them comply with safety standards, in particular by adding cabin doors.

Le problème général qui se pose est donc de tranformer, aux moindres frais possibles, les installations existantes pour les rendre conformes aux normes de sécurité. Pour cela, une première difficulté tient à la faible largeur de la gaine qui ne permet pas en général l'installation des simples portes coulissantes utilisées sur la plupart des ascenseurs modernes. On est donc obligé d'avoir recours à des portes accordéon ou télescopiques. Une autre difficulté tient à la faible profondeur de la cabine, que l'on peut difficile­ment restreindre encore davantage en prévoyant les zones de balayage nécessaires pour le fonctionnement des portes accordéon. Une troi­sième difficulté tient à la faible distance qui existe entre la cabine et la paroi lisse qui permet difficilement l'installation de portes coulissantes télescopiques à éléments multiples, ou en tout cas, lorsque cela est possible, ces portes en s'ouvrant balaient une zone qui interfère avec les leviers de manoeuvre des serrures de portes palières et avec la colonne électrique connectant les contacts de sécurité et les boutons d'appel de paliers. Il en résulte, dans la plupart des cas, une nécessité de déplacer cette colonne et de chan­ger ou de transformer les serrures, ou au moins leurs leviers de manoeuvre, ce qui entraîne un coût important de fournitures et de main d'oeuvre.The general problem that arises is therefore to transform, at the lowest possible cost, the existing installations to bring them into compliance with safety standards. For this, a first difficulty is due to the small width of the shaft which generally does not allow the installation of simple sliding doors used on most modern elevators. We are therefore obliged to use accordion or telescopic doors. Another difficulty stems from the shallow depth of the cabin, which can hardly be further restricted by providing for the scanning zones. necessary for the operation of the accordion doors. A third difficulty is due to the small distance which exists between the cabin and the smooth wall which makes it difficult to install telescopic sliding doors with multiple elements, or in any case, when possible, these doors by opening sweep an area which interferes with the operating levers of the landing door locks and with the electrical column connecting the safety contacts and the landing call buttons. This results, in most cases, a need to move this column and to change or transform the locks, or at least their operating levers, which results in a significant cost of supplies and labor.

Le but de l'invention est d'éliminer les inconvénients précé­dents, en particulier en réalisant une porte télescopique pour une cabine d'ascenseur qui non seulement soit de faible encombrement en épaisseur, mais qui en outre évite d'interférer, au moins d'un côté, avec les installations existantes.The object of the invention is to eliminate the above drawbacks, in particular by providing a telescopic door for an elevator car which not only is compact in thickness, but which also avoids interfering, at least one side, with existing facilities.

L'invention consiste à fermer l'ouverture de la cabine par trois panneaux, dont un panneau latéral isolé coulissant vers l'extérieur du côté où se trouve la colonne électrique et les ou la majorité des serrures de portes palières, un panneau latéral télescopique du côté opposé et coulissant également vers l'extérieur, et un panneau cen­tral combiné avec le panneau télescopique et se déplaçant par rapport au panneau télescopique en même temps que celui-ci se déplace par rapport à la cabine, les trois panneaux étant constitués par un panneau de tôle à bords tombés vers l'extérieur de la cabine, excepté le bord du panneau central qui est du côté du panneau télescopique et qui est orienté vers l'intérieur de la cabine pour se loger et se déplacer dans l'espace occupé et balayé par ce panneau télescopique, tandis que le panneau isolé comporte un premier bord du côté du panneau central dont l'épaisseur embrasse à la fois l'épaisseur du panneau télescopique et du panneau central, et un bord opposé d'épaisseur beaucoup plus faible se déplaçant au-delà de la zone occupée par la colonne électrique et les galets de manoeuvre des serrures palières sans interférer avec ceux-ci.The invention consists in closing the cabin opening by three panels, including an insulated side panel sliding outwards on the side where the electrical column is located and the or most of the landing door locks, a telescopic side panel of the opposite side and also sliding towards the outside, and a central panel combined with the telescopic panel and moving relative to the telescopic panel at the same time as the latter moves relative to the cabin, the three panels being constituted by a panel of sheet metal with edges falling towards the outside of the cabin, except the edge of the central panel which is on the side of the telescopic panel and which is oriented towards the inside of the cabin for lodging and moving in the occupied and swept space by this telescopic panel, while the insulated panel has a first edge on the side of the central panel whose thickness embraces both the thickness of the telescopic panel and the central panel, and an op edge laid with a much smaller thickness moving beyond the area occupied by the electrical column and the rollers for operating the landing locks without interfering with them.

D'autres particularités de l'invention apparaîtront dans la description qui va suivre d'un mode de réalisation pris comme exemple et représenté sur le dessin annexé, sur lequel la figure unique représente une coupe horizontale partielle de l'installation.Other features of the invention will appear in the following description of an embodiment taken as an example and shown in the attached drawing, in which the single figure represents a partial horizontal section of the installation.

On voit sur cette figure la cabine 1 de l'ascenseur se déplaçant dans la gaine 2, avec les portes palières 3, dont les surfaces inté­rieures 4 sont toutes disposées dans un même plan vertical et raccor­dées entre elles dans l'intervalle entre les étages par la paroi intérieure de la gaine ou un remplissage approprié non représenté, de manière à constituer une paroi lisse sur toute la hauteur de la gaine, tout au moins tant que toutes les portes 3 sont fermées.We see in this figure the cabin 1 of the elevator moving in the shaft 2, with the landing doors 3, the interior surfaces 4 of which are all arranged in the same vertical plane and connected together in the interval between the floors by the inner wall of the sheath or a suitable filling, not shown, so as to constitute a smooth wall over the entire height of the sheath, at least as long as all the doors 3 are closed.

Chacune des portes palières 3 est verrouillée par une serrure mécanique 5, dont le levier de manoeuvre 6 comporte un galet 7, qui peut agir dans le sens des panneaux, comme dans l'exemple représenté, ou perpendiculairement à ceux-ci, et qui est actionné au passage par une came fixe non représentée solidaire de la cabine 1, afin de n'autoriser l'ouverture manuelle de la porte 3, dans le sens repré­senté par la flèche 8, que lorsque la cabine se trouve au niveau de cette porte. On voit également le fourreau 9 contenant la colonne électrique qui réunit les contacts d'ouverture des portes 3 et les boutons d'appel des paliers successifs, non représentés.Each of the landing doors 3 is locked by a mechanical lock 5, the operating lever 6 of which comprises a roller 7, which can act in the direction of the panels, as in the example shown, or perpendicular to them, and which is actuated in passing by a fixed cam, not shown, integral with the cabin 1, in order to authorize the manual opening of the door 3, in the direction represented by the arrow 8, only when the cabin is at this door. We also see the sheath 9 containing the electrical column which brings together the opening contacts of the doors 3 and the call buttons of the successive bearings, not shown.

En général, la dimension intérieure de la cabine 1 est plus large que le passage de la porte 3, et des retours de cabine 10 sont prévus de chaque côté ou d'un seul. Par ailleurs, un seuil de cabine non représenté vient se raccorder avec le minimum de jeu avec la paroi lisse, en même temps que des retours d'entrée 11, constitués en général par une simple tôle, viennent également se raccorder avec la paroi lisse pour ne laisser qu'un intervalle minimum insuffisant pour passer la main.In general, the interior dimension of the cabin 1 is wider than the passage of the door 3, and cabin returns 10 are provided on each side or only one. Furthermore, a cabin threshold, not shown, is connected with the minimum clearance with the smooth wall, at the same time as the inlet returns 11, generally constituted by a single sheet, also come to be connected with the smooth wall for leave only a minimum interval insufficient to pass the hand.

La porte de cabine selon l'invention doit donc pouvoir se loger entre les retours 10 et la paroi lisse, en réduisant ou en changeant les retours d'entrée 11, et en changeant éventuellement le seuil pour le remplacer par un seuil avec rainures de guidage.The cabin door according to the invention must therefore be able to be housed between the returns 10 and the smooth wall, by reducing or changing the inlet returns 11, and possibly changing the threshold to replace it with a threshold with guide grooves .

Pour cela, la porte selon l'invention comporte trois panneaux 12, 13 et 14 pour une ouverture asymétrique, à savoir :
- un panneau latéral isolé 12 du côté occupé par la colonne 9 et les serrures 5;
- un panneau latéral télescopique 14 du côté opposé; et
- un panneau central 13 remplissant l'espace entre les deux panneaux latéraux 12 et 14.For this, the door according to the invention comprises three panels 12, 13 and 14 for an asymmetrical opening, namely:
- an insulated side panel 12 on the side occupied by the column 9 and the locks 5;
- a telescopic side panel 14 on the opposite side; and
a central panel 13 filling the space between the two side panels 12 and 14.

Le panneau latéral télescopique 14 est constitué par un panneau de tôle comportant un premier bord tombé 15 dirigé vers l'extérieur de la cabine et un deuxième bord tombé 16 également dirigé vers l'extérieur de la cabine. Par coulissement dans le sens représenté par la flèche 17, le panneau 14 vient occuper la position 14a en traits interrompus sur la figure. Le panneau central 13 comporte également un premier bord tombé 18 semblable au bord 15, et un deuxième bord tombé 19 qui présente la particularité d'être dirigé vers l'intérieur de la cabine de manière à se loger et se déplacer à l'intérieur de l'espace occupé et balayé par le panneau 14 lors de l'ouverture. Lorsque le panneau 13 s'ouvre dans le sens représenté par la flèche 20, à vitesse double de la vitesse 17 du panneau 14, il vient occuper la position représentée en 13a en traits interrompus sur la figure, où l'on voit que les bords 19 et 16 viennent s'em­boîter l'un dans l'autre en fin de course d'ouverture complète en 16a et 19a.The telescopic side panel 14 is constituted by a sheet metal panel comprising a first fallen edge 15 directed towards the outside of the cabin and a second fallen edge 16 also directed towards the outside of the cabin. By sliding in the direction shown by arrow 17, the panel 14 occupies the position 14a in broken lines in the figure. The central panel 13 also has a first dropped edge 18 similar to the edge 15, and a second dropped edge 19 which has the particularity of being directed towards the interior of the cabin so as to be housed and move inside. the space occupied and scanned by the panel 14 during opening. When the panel 13 opens in the direction represented by the arrow 20, at twice the speed of the speed 17 of the panel 14, it comes to occupy the position shown in 13a in broken lines in the figure, where it can be seen that the edges 19 and 16 fit into one another at the end of the full opening stroke in 16a and 19a.

Par ailleurs, le panneau latéral isolé 12 comporte également un premier bord tombé 21 du côté du panneau central 13, ce bord 21 ayant une dimension dans le sens de l'épaisseur qui embrasse à la fois les épaisseurs des panneaux 13 et 14, c'est-à-dire par conséquent des bords 18 et 15, ce qui donne au panneau 12 une grande raideur. En contrepartie, le bord opposé 22 peut être de très faible dimension dans le sens de l'épaisseur, ce qui permet, lors de l'ouverture du panneau 12 dans le sens de la flèche 23, d'éviter que ce bord 22, qui se déplace jusqu'en 22a, ne vienne interférer avec l'emplacement occupé par la colonne 9 et les galets 7. Bien entendu, le premier bord tombé 21 comporte une came 24 pour la manoeuvre du galet 7, en remplacement de la came portée habituellement par la cabine.Furthermore, the insulated side panel 12 also has a first fallen edge 21 on the side of the central panel 13, this edge 21 having a dimension in the direction of the thickness which embraces both the thicknesses of the panels 13 and 14, it that is to say therefore edges 18 and 15, which gives the panel 12 a great stiffness. In return, the opposite edge 22 can be very small in the direction of the thickness, which makes it possible, when opening the panel 12 in the direction of the arrow 23, to prevent this edge 22, which moves up to 22a, does not come to interfere with the location occupied by the column 9 and the rollers 7. Of course, the first fallen edge 21 comprises a cam 24 for the operation of the roller 7, replacing the cam usually carried by the cabin.

C'est cette disposition fortement dissymétrique, à la fois du mode d'ouverture des trois panneaux et des bords du panneau latéral isolé 12, qui permet d'éviter la transformation et le déplacement des organes existants 5, 6, 7 et 9. En outre, la disposition particulière inversée du bord 19 du panneau central 13 permet de dégager également un large espace du côté opposé, ce qui présente un intérêt tout particulier dans le cas où l'installation comporte à certains des étages une porte semblable à 3 mais s'ouvrant dans le sens inverse, ce qui implique par conséquent la présence de la serrure 5 corres­pondante du côté opposé et d'une came supplémentaire 25 placée dans le rebord 18. Etant donné que le bord 16 est plus épais que le bord 22, il est possible que, dans ce cas, l'on soit amené à modifier le levier 6 ou l'axe du galet 7 correspondant, mais cette transformation n'intéresse en général qu'un seul étage ou un nombre très réduit de ceux-ci.It is this highly asymmetrical arrangement, both of the way in which the three panels are opened and the edges of the side panel insulated 12, which avoids the transformation and displacement of the existing members 5, 6, 7 and 9. In addition, the particular inverted arrangement of the edge 19 of the central panel 13 also makes it possible to release a large space on the opposite side, this which is of particular interest in the case where the installation comprises on some of the stages a door similar to 3 but opening in the opposite direction, which consequently implies the presence of the corresponding lock 5 on the opposite side and an additional cam 25 placed in the rim 18. Since the edge 16 is thicker than the edge 22, it is possible that, in this case, it is necessary to modify the lever 6 or the axis of the roller 7 corresponding, but this transformation generally only interests a single stage or a very reduced number of these.

Naturellement, le guidage et la manoeuvre des trois panneaux sont assurés par un mécanisme non représenté, situé au-dessus de la cabine, et d'une conception tout à fait classique, mis à part la dissymétrie qui se trouve imposée. Par exemple, les deux panneaux lents 12 et 14 peuvent être manoeuvrés par deux bielles à partir d'un plateau tournant, et l'unique panneau rapide 13 peut être déplacé à vitesse double à partir du panneau 14 par un mouflage classique à câble. La base des panneaux coulisse naturellement dans les rainures de guidage du seuil indiquées plus haut.Naturally, the guiding and the operation of the three panels are ensured by a mechanism (not shown), located above the cabin, and of a completely classic design, apart from the asymmetry which is imposed. For example, the two slow panels 12 and 14 can be maneuvered by two connecting rods from a turntable, and the single rapid panel 13 can be moved at double speed from the panel 14 by a conventional cable reeving. The base of the panels naturally slides in the threshold guide grooves indicated above.

On voit donc que, grâce à l'invention, on peut constituer un ensemble standard de mécanisme et de portes, éventuellement de diver­ses largeurs d'ouverture, qui s'adapte à peu de frais à la plupart des cas, en n'ayant qu'à réduire ou changer les retours d'entrée 11 et à changer le seuil pour rajouter l'ensemble standard, et en n'ayant surtout en général aucune transformation à opérer sur le reste de l'installation existante, ce qui est un avantage économique considérable. Naturellement, selon la position des serrures 5, ou de la majorité des serrures, on utilise la disposition représentée, ou la disposition inversée par symétrie.It can therefore be seen that, thanks to the invention, it is possible to constitute a standard set of mechanism and doors, possibly of various opening widths, which adapts inexpensively to most cases, having only '' to reduce or change the input returns 11 and to change the threshold to add the standard assembly, and above all in general having no transformation to operate on the rest of the existing installation, which is an economic advantage considerable. Naturally, depending on the position of the locks 5, or of the majority of the locks, the arrangement shown is used, or the arrangement inverted by symmetry.
