Description

La présente invention a pour objet un élévateur destiné à transporter des personnes entre un niveau inférieur et un niveau supérieur. Cet élévateur est principalement destiné à être installé dans les habitations particulières pour faciliter l'accès à l'étage des utilisateurs dont la mobilité est réduite, par exemple, des personnes âgées.The present invention relates to an elevator intended to transport people between a lower level and a higher level.

Sur une telle installation, les sécurités sont habituellement obtenues par des systèmes électriques constitués, par exemple, de verrous électromagnétiques associés à des détecteurs, l'ensemble étant piloté par une armoire renfermant les différents circuits de commande. La complexité d'un tel dispositif se traduit par des coûts d'achat, de mise en oeuvre et de maintenance qui sont, en général, dissuasifs pour le particulier. Une façon de rendre un tel élévateur accessible au particulier consiste à réaliser toutes les fonctions à l'aide de moyens mécaniques simples, fiables et ne nécessitant qu'une maintenance simplifiée. La fonction motrice pourra, par exemple, être réalisée à l'aide d'un vérin à double allongement et à vitesse constante comme celui décrit dans le document FR 9311277 au nom du demandeur. Il reste néanmoins à assurer la sécurité et, en particulier, à gérer le verrouillage des portes à l'aide d'un dispositif mécanique simple. La présente invention vise à procurer un élévateur muni d'un tel dispositif.On such an installation, the safety devices are usually obtained by electrical systems made, for example, of electromagnetic locks associated with detectors, the whole being controlled by a cabinet containing the various control circuits.

L'élévateur selon l'invention est uniquement destiné à assurer le transfert entre deux niveaux comme il est représenté en perspective sur la figure 1, sur laquelle on a volontairement omis de représenter, pour des raisons de simplicité, les moyens assurant l'élévation de la cabine 1 de l'élévateur, moyens qui n'entrent pas dans l'objet de l'invention. La cabine 1 est fermée par une porte 2 à battant s'ouvrant sur l'extérieur, ladite cabine 1 se translatant verticalement depuis un niveau inférieur jusque dans une cage 3, située à un niveau supérieur et constituée par un garde-corps 4 fermé par une porte palière 5 à battant. Dans la variante particulièrement simple, représentée sur les figures, la cabine 1 est constituée de trois parois verticales disposées en "U" fermées par la porte 2 et montées sur un plancher 6. La cabine 1 se déplace le long de rails de guidage non représentés sur les figures, fixés par exemple à un mur porteur de l'habitation et parallèles à la face extérieure de la paroi 7 de ladite cabine 1, opposée à la porte 2. Selon cette même variante, l'élévateur est dépourvu de cage au niveau inférieur, l'utilisateur accédant directement à la cabine 1 lorsque celle-ci repose sur le niveau inférieur, comme il est représenté sur la figure 4. La porte palière 5, qui s'ouvre vers l'extérieur de la cabine 1 est disposée de façon à se trouver en face de la porte 2 lorsque la cabine 1 est au niveau supérieur, les articulations desdites portes 2 et 5 étant situées du même côté, comme il est représenté sur la figure 1.The elevator according to the invention is only intended for ensure the transfer between two levels as it is shown in perspective in Figure 1, on which we have willfully failed to represent, for reasons of simplicity, the means ensuring the elevation of the cabin 1 the elevator, means which do not enter the object of the invention. Cab 1 is closed by a swing door 2 opening onto the outside, said cabin 1 translating vertically from a lower level into a cage 3, located on a higher level and constituted by a guardrail 4 closed by a hinged landing door 5. In the particularly simple variant, shown on figures, cabin 1 is made up of three walls vertical arranged in "U" closed by door 2 and mounted on a floor 6. The car 1 moves along rails of guidance not shown in the figures, fixed for example to a load-bearing wall of the house and parallel to the face exterior of the wall 7 of said cabin 1, opposite the door 2. According to this same variant, the elevator is devoid of cage at the lower level, the user accessing directly to cabin 1 when it rests on the lower level, as shown in Figure 4. The landing door 5, which opens to the outside of cabin 1 is arranged so that it is opposite door 2 when cabin 1 is on the upper level, the articulations of said doors 2 and 5 being located in the same side, as shown in Figure 1.

De façon à assurer la sécurité de l'utilisateur, l'élévateur possède des moyens qui, bien que tous de type passif et entièrement mécanique, conditionnent le mouvement de translation verticale de la cabine 1, le verrouillage et le déverrouillage des portes 2 et 5 conformément à l'invention.In order to ensure user safety, the elevator has means which, although all of the type passive and fully mechanical, condition the movement vertical translation of cabin 1, locking and unlocking doors 2 and 5 in accordance with the invention.

Tout d'abord, l'élévateur possède un bras de verrouillage 8 monté à rotation autour d'un axe solidaire de la cabine 1. Cet axe peut, par exemple, comme c'est le cas sur les figures 1,2 et 4, être horizontal et disposé dans la paroi 7. Ce bras de verrouillage 8 oscille alors le long de la paroi latérale 9 de la cabine 1 située diagonalement à l'opposé de l'articulation de la porte 2 de la cabine 1. Il se prolonge, au-delà de ladite paroi 7, par une came 10 destinée à collaborer avec une butée 11 verticale fixe disposée le long du trajet de la cabine 1. Lorsque cette dernière se situe quelque part entre le niveau inférieur et le niveau supérieur, comme il est représenté sur la figure 1, le bras de verrouillage 8, en position horizontale, fait alors office de rambarde de maintien et surtout, assure le verrouillage de la porte 2 de la cabine 1 par accrochage de son extrémité libre 8a dans un mentonnet 12 placé sur la face interne de la porte 2. Ce verrouillage est rendu inviolable entre les niveaux inférieur et supérieur grâce à la position relative de la face postérieure 10b de la came 10 et de la butée 11, qui est positionnée par rapport à la cabine 1 de façon à maintenir un jeu relatif suffisant pour permettre la translation de la came 10 le long de ladite butée 11 tout en interdisant le basculement du bras de verrouillage 8. La longueur de la butée 11 est choisie de façon à n'autoriser le déverrouillage du bras de verrouillage 8, et par suite celui de la porte 2 de la cabine 1, que lorsque celle-ci est en bonne place aux niveaux supérieur et inférieur. Il est clair, que tout autre forme de coopération entre une came solidaire du bras de verrouillage 8 et une butée disposée le long de l'élévateur est à la portée de l'homme du métier et ne sortirait pas du cadre de l'invention.First of all, the elevator has a locking arm 8 mounted for rotation about an axis integral with the cabin 1. This axis can, for example, as is the case in FIGS. 1, 2 and 4, be horizontal and disposed in the wall 7. This locking arm 8 then oscillates along the side wall 9 of the cabin 1 located diagonally opposite the articulation of the door 2 of the cabin 1. It extends, beyond said wall 7, by a cam 10 intended to collaborate with a fixed vertical stop 11 arranged along the path of the cabin 1. When the latter is located somewhere between the lower level and the upper level, as is shown in Figure 1, the lock arm 8 in a horizontal position, then acts as retaining and especially rail, ensures locking of the door 2 of the car 1 by gripping its free end 8 has a flange 12 placed on the inside of door 2. This locking is made inviolable between the lower and upper levels by virtue of the relative position of the rear face 10b of the cam 10 and of the stopper 11, which is positioned relative to the cabin 1 so as to maintain sufficient relative clearance to allow translation of the cam 10 along the said stop 11 while preventing the tilting of the locking arm 8. The length of the stop 11 is chosen so as to not allow the unlocking of the locking arm 8, and consequently that of the door 2 of cabin 1, only when it is in good position at the upper and lower levels. It is clear that any other form of cooperation between a cam secured to the locking arm 8 and a stop disposed along the elevator is within the reach of those skilled in the art and would not depart from the scope of the invention.

Lorsque ladite cabine 1 arrive au niveau supérieur, le bras de verrouillage 8 est alors automatiquement déverrouillé par une butée prenant, par exemple, la forme d'une cale élastique 13 représentée sur la figure 2 et disposée dans le prolongement vertical de l'extrémité supérieure 11b de la butée 11 verticale fixe. Ladite cale 13 procure, par accrochage avec la came 10, lors de l'arrivée de la cabine 1 au niveau supérieur, un soulèvement du bras de verrouillage 8 sur un angle suffisant pour provoquer la sortie de son extrémité libre 8a hors du mentonnet 12. Il ne reste plus alors, à l'occupant de la cabine 1, qu'à ramener le bras de verrouillage 8 en position verticale et ensuite, à ouvrir la porte 2, pour sortir de ladite cabine 1. Le mouvement vertical descendant ne sera à nouveau possible, qu'après fermeture de la porte 2, qui autrement viendrait bloquer le mouvement descendant par appui de son battant sur le sol du niveau supérieur. Cette dernière condition étant remplie, le mouvement descendant va provoquer, par coopération de la face postérieure 10b de la came 10 avec l'extrémité supérieure 11b de la butée 11, le basculement en position horizontale dudit bras de verrouillage 8 autour de son axe de rotation, et par suite le verrouillage de la porte 2 par accrochage de l'extrémité libre 8a du bras de verrouillage 8 dans le mentonnet 12.When said cabin 1 arrives at the upper level, the locking arm 8 is then automatically unlocked by a stop taking, for example, the form of an elastic wedge 13 shown in FIG. 2 and arranged in the vertical extension of the upper end 11 b of the fixed vertical stop 11. Said wedge 13 provides, by hooking with the cam 10, when the cabin 1 arrives at the upper level, a lifting of the locking arm 8 at an angle sufficient to cause its free end 8 a to come out of the spar 12 It then only remains for the occupant of cabin 1 to return the locking arm 8 to the vertical position and then to open the door 2 to exit from said cabin 1. The vertical downward movement will only be again possible, only after closing door 2, which would otherwise block the downward movement by pressing its leaf on the floor of the upper level. This latter condition being fulfilled, the downward movement will cause, by cooperation of the rear face 10b of the cam 10 with the upper end 11b of the stop 11, the tilting of said locking arm 8 around its axis of rotation, and consequently the locking of the door 2 by hooking the free end 8 a of the locking arm 8 in the chin 12.

Lorsque, au contraire la cabine 1 arrive au niveau inférieur, le bras de verrouillage 8 est alors automatiquement déverrouillé par une butée inférieure consistant par exemple en une canne élastique 14 solidaire, à son extrémité supérieure 14a, du bras de verrouillage 8 et traversant le plancher 6 de la cabine par son extrémité inférieure 14b, comme il est représenté sur la figure 4. La longueur de ladite extrémité inférieure 14b est choisie de manière à procurer, lors de l'arrivée de la cabine 1 au niveau inférieur, le soulèvement du bras de verrouillage 8 sur un angle suffisant pour provoquer la sortie de son extrémité libre 8a hors du mentonnet 12. Il ne reste plus alors, à l'occupant de la cabine 1, qu'à ramener le bras de verrouillage 8 en position verticale et ensuite, à ouvrir la porte 2, pour sortir de ladite cabine 1. Le départ vers le niveau supérieur ne sera, à nouveau possible, qu'après fermeture de la porte 2 et rabattement du bras de verrouillage 8. En effet, tant que ce dernier se trouve en position relevée, hors du mentonnet 12, la came 10 bloque le mouvement vertical ascendant de la cabine 1 par accrochage de sa face antérieure 10a sur l'extrémité inférieure 11a de la butée 11. Les différentes interdictions réalisées par la combinaison entre la came 10 et la butée 11 sont rendues possibles grâce à la géométrie particulière de ladite came 10. Dans la variante représentée sur les figures, cette géométrie se traduit par une hauteur de la came 10, au-dessus de l'axe de rotation du bras de verrouillage 8, supérieure à sa longueur derrière ledit axe. Dans les faits, la butée 11 n'accompagne pas la came 10 jusque dans sa position la plus basse, correspondant à la cabine 1 au repos sur le niveau inférieur. En effet, la canne élastique 14 provoque un début de soulèvement du bras de verrouillage 8 avant cette position, puisqu'elle dépasse en-dessous du plancher 6 de la cabine 1 ; il est donc nécessaire que la came 10 soit libérée de son appui le long de la butée 11 avant que la cabine 1 n'ait atteint sa position de repos sur le niveau inférieur. La buttée 11 est donc plus courte d'une dizaine de centimètres. Il est donc possible de débuter le mouvement ascendant avec le bras de verrouillage 8 en position relevée et déverrouillée. Néanmoins, ce mouvement sera stoppé après une montée d'une dizaine de centimètres, la face antérieure 10a de la came 10 venant buter sur l'extrémité inférieure 11a de la butée 11. De plus, il est à priori possible de débuter le mouvement ascendant sans avoir fermé la porte 2, il suffit pour cela d'abaisser le bras de verrouillage 8. Dans les faits, on remédie à cet inconvénient en fixant au plafond une butée, par exemple sous forme d'un arceau, non représenté sur les figures, qui descend jusqu'au-dessus du niveau du haut du battant de la porte 2.When, on the contrary, the cabin 1 arrives at the lower level, the locking arm 8 is then automatically unlocked by a lower stop consisting for example of an elastic rod 14 secured, at its upper end 14 a , to the locking arm 8 and passing through the floor 6 of the cabin by its lower end 14b , as shown in FIG. 4. The length of said lower end 14b is chosen so as to provide, when the cabin 1 arrives at the lower level, the lifting of the locking arm 8 at an angle sufficient to cause its free end 8 a to exit the jib 12. It then only remains for the occupant of cabin 1 to bring the locking arm 8 back. vertical position and then, to open door 2, to exit from said cabin 1. Departure to the upper level will only be possible again after closing door 2 and folding down the control arm 8. In fact, as long as the latter is in the raised position, outside of the spar 12, the cam 10 blocks the upward vertical movement of the cabin 1 by hooking its front face 10 a on the lower end 11 a of the stop 11. The various prohibitions made by the combination between the cam 10 and the stop 11 are made possible thanks to the particular geometry of said cam 10. In the variant shown in the figures, this geometry results in a height of the cam 10 , above the axis of rotation of the locking arm 8, greater than its length behind said axis. In fact, the stop 11 does not accompany the cam 10 until in its lowest position, corresponding to the cabin 1 at rest on the lower level. Indeed, the elastic rod 14 causes a start of lifting of the locking arm 8 before this position, since it protrudes below the floor 6 of the cabin 1; it is therefore necessary for the cam 10 to be released from its support along the stop 11 before the cabin 1 has reached its rest position on the lower level. The abutment 11 is therefore shorter by about ten centimeters. It is therefore possible to start the upward movement with the locking arm 8 in the raised and unlocked position. However, this movement will be stopped after an increase of about ten centimeters, the anterior surface 10a of the cam 10 abutting on the lower end 11a of the stopper 11. In addition, it is a priori possible to start the upward movement without having closed the door 2, it suffices to lower the locking arm 8. In practice, this drawback is remedied by fixing a stop to the ceiling, for example in the form of an arch, not shown on the figures, which descends to above the level of the top of the door leaf 2.

Selon une variante particulière représentée sur la figure 1, le bras de verrouillage 8 est solidarisé à un second bras 8' monté à rotation autour du même axe, le long de la paroi latérale 15 de la cabine 1 située du côté de l'articulation de la porte 2, ledit second bras 8' constituant ainsi une seconde rambarde de maintien rabattable. Le bras de verrouillage 8 et le second bras 8' peuvent éventuellement se rejoindre à leurs extrémités libres 8a, 8'a pour constituer un arceau de maintien rabattable.According to a particular variant shown in Figure 1, the locking arm 8 is secured to a second arm 8 'rotatably mounted about the same axis, along the side wall 15 of the cabin 1 located on the side of the articulation of door 2, said second arm 8 ′ thus constituting a second folding support railing. The locking arm 8 and the second arm 8 ′ can optionally meet at their free ends 8 a , 8 ′ a to form a folding retaining arch.

L'élévateur selon l'invention possède également une coulisse, montée pivotante dans le plan de la porte palière 5 du côté de la cabine 1. Cette coulisse forme une clenche 16 venant verrouiller la porte palière 5 dans un mentonnet 17 solidaire du garde-corps 4 et situé à l'opposé de l'articulation de la porte palière 5.The elevator according to the invention also has a runner, pivotally mounted in the plane of the landing door 5 on the side of cabin 1. This slide forms a latch 16 locking the landing door 5 in a chin 17 integral with the railing 4 and located opposite the articulation of the landing door 5.

Selon une première variante, non représentée sur les figures, la clenche 16 est constituée par un profilé de section en "L" constitué d'une aile principale 18, montée à rotation par une de ses extrémités 18a, dans le plan de la porte palière 5, autour d'un axe perpendiculaire à ladite porte 5 et coopérant, par son autre extrémité 18b, avec le mentonnet 17 de la porte palière 5. L'aile principale 18 est bordée sur sa longueur par une aile latérale supérieure 18c s'étendant d'abord perpendiculairement à ladite aile principale 18 en direction de la cabine 1, puis ensuite parallèlement et le long de l'aile principale 18, de façon à former une glissière.According to a first variant, not shown in the figures, the latch 16 is formed by an "L" section profile consisting of a main wing 18, rotatably mounted by one of its ends 18 a , in the plane of the door landing 5, around an axis perpendicular to said door 5 and cooperating, by its other end 18 b , with the jib 17 of the landing door 5. The main wing 18 is bordered along its length by an upper lateral wing 18 c first extending perpendicularly to said main wing 18 in the direction of the cabin 1, then then parallel and along the main wing 18, so as to form a slide.

Selon une deuxième variante préférentielle représentée sur la figure 3a, la clenche 16 est constituée par un profilé de section en "C" constitué de la même aile principale 18 qui est bordée, en plus, par une aile latérale inférieure 18d. Les ailes latérales supérieure 18c et inférieure 18d s'étendent d'abord perpendiculairement à ladite aile principale 18 en direction de la cabine 1 puis ensuite en direction l'une de l'autre, parallèlement à l'aile principale 18, de façon à former une glissière, l'aile latérale supérieure 18c dépassant, du côté de l'extrémité 18b coopérant avec le mentonnet 17, par rapport à l'aile latérale inférieure 18d.According to a second preferred variant shown in FIG. 3 a , the latch 16 is constituted by a section section in “C” made up of the same main wing 18 which is bordered, in addition, by a lower lateral wing 18 d . The upper 18 c and lower 18 d lateral wings first extend perpendicular to said main wing 18 in the direction of the cabin 1 and then in the direction of one another, parallel to the main wing 18, so to form a slide, the upper lateral wing 18 c protruding from the side of the end 18 b cooperating with the flange 17, relative to the lower lateral wing 18 d .

Le mentonnet 17 consiste en une découpe pratiquée dans l'épaisseur dudit garde-corps 4, débouchant à l'opposé de la cabine 1 et délimitée par un premier bord 17a horizontal, prolongé, vers le bas et du côté de la cabine 1, par un deuxième bord 17b vertical, lui-même prolongé vers l'extérieur de la cabine 1 par un troisième bord 17c horizontal, lui-même prolongé vers le haut par un quatrième bord 17d vertical, lui-même prolongé vers le haut et vers l'extérieur de la cabine 1 par un cinquième bord 17e constituant une rampe oblique et se prolongeant par un sixième bord 17f vertical se terminant à la verticale de l'origine du premier bord 17a, et à une distance de ce premier bord 17a supérieure à la largeur de l'aile principale 18 de la clenche 16. Le deuxième bord 17b vertical, le troisième bord 17c horizontal et le quatrième bord 17d vertical définissent une fente verticale destinée à recevoir l'extrémité 18b de la clenche 16 qui, lorsqu'elle s'y trouve engagée à fond, est inclinée en contre-bas de son axe d'articulation perpendiculairement à la porte palière 5. Cette première variante est représentée sur les figures 3a et 3b. Une variante minimale assurant un bon fonctionnement est représentée sur la figure 3c. Le mentonnet 17 comporte uniquement le quatrième bord 17d vertical et le cinquième bord 17e constituant la rampe oblique. L'arrêt en rotation de la porte palière 5 n'est plus alors réalisé par l'intermédiaire de la clenche 16, mais par un couvre-joint, disposé le long du bord vertical extérieur du battant de la porte palière 5 et qui vient prendre appui sur le garde-corps 4. De même, l'arrêt en rotation de la clenche 16 est alors réalisé par une butée prévue sur la porte palière 5.The chin 17 consists of a cutout made in the thickness of said railing 4, opening opposite the cabin 1 and delimited by a first edge 17 a horizontal, extended, downward and on the side of the cabin 1, by a second vertical edge 17 b , itself extended towards the outside of the cabin 1 by a third horizontal edge 17 c , itself extended upwards by a fourth vertical edge 17 d , itself extended upwards and towards the outside of cabin 1 by a fifth edge 17 e constituting an oblique ramp and extending by a sixth vertical edge 17 f ending vertically from the origin of the first edge 17 a , and at a distance from this first edge 17 a greater than the width of the main wing 18 of the latch 16. The second edge 17 b vertical, the third edge 17 c horizontal and the fourth edge 17 d vertical define a vertical slot intended to receive the end 18 b of latch 16 which, when e lle therein fully engaged, is inclined against below its axis of articulation perpendicular to the landing door 5. This first variant is shown in Figures 3 a and 3 b. A minimum variant ensuring proper operation is shown in Figure 3 c . The chin 17 only has the fourth vertical edge 17 d and the fifth edge 17 e constituting the oblique ramp. The stop in rotation of the landing door 5 is no longer then carried out by means of the latch 16, but by a joint cover, disposed along the outer vertical edge of the leaf of the landing door 5 and which comes to take support on the railing 4. Similarly, the stop in rotation of the latch 16 is then achieved by a stop provided on the landing door 5.

Ladite clenche 16 coopère avec un téton faisant saillie à la surface extérieure de la porte 2 de la cabine 1, qui, lorsque la cabine 1 atteint le niveau supérieur, vient s'engager dans la coulisse pour lever la clenche 16 hors du mentonnet 17 et déverrouiller ainsi la porte palière 5 supérieure. Dans le cas où l'aile principale 18 de la clenche 16 ne possède pas d'aile inférieure 18d, ce téton peut consister en une tige, non représentée sur les figures, en forme de "L" dont la jambe est disposée horizontalement et fixée, par son extrémité libre, perpendiculairement à la surface extérieure de la porte 2, de façon à ce que le pied du "L" soit vertical et orienté vers le haut. Dans le cadre de la variante préférentielle représentée sur les figures 2 et 3, dans laquelle l'aile principale 18 de la clenche 16 possède une aile inférieure 18d, le téton est constitué d'une tige 19 en forme de "T" dont le pied 19a, disposé horizontalement, est fixé, par son extrémité libre, perpendiculairement à la surface extérieure de la porte 2 de façon à ce que la barre horizontale 19b du "T" soit verticale. Lors de l'arrivée de la cabine 1 au niveau supérieur, l'extrémité supérieure de la barre 19b du "T" vient s'insérer entre l'aile principale 18 et l'aile latérale supérieure 18c, du côté de l'extrémité 18b de la clenche 16, bénéficiant pour cela, de la longueur réduite de l'aile inférieure 18d. Le téton 19 est disposé sur la porte 2 de la cabine 1, de sorte que, lorsque ladite cabine 1 a atteint sa hauteur maximale dans la cage 3, ledit téton 19 ait entraíné, dans son mouvement vertical, la clenche 16 suffisamment haut, pour que son extrémité 18b se situe au-dessus du niveau du sixième bord 17f horizontal du mentonnet 17. La porte palière 5 se trouve ainsi déverrouillée. De plus, la longueur de l'aile inférieure 18d est telle que, lorsque la clenche 16 a terminé le mouvement de rotation qui l'a amenée en position déverrouillée, l'extrémité de ladite aile inférieure 18d se trouve en dessous de l'extrémité inférieure de la barre 19b du "T", comme représenté en traits pleins sur la figure 3a. Le téton 19 se trouve alors engagé par les deux extrémités de la barre 19b de son "T" dans la glissière constituée par les ailes latérales supérieure 18c et inférieure 18d de la clenche 16. La porte palière 5 et la porte 2 de la cabine 1 sont alors solidarisées en rotation autour de leurs articulations respectives, l'ouverture ou la fermeture de l'une entraínant celle de l'autre et inversement. Le décalage existant entre les articulations des deux portes 2 et 5 est compensé, lors de la manoeuvre desdites portes 2 et 5 par le glissement de la barre 19b du "T" dans la glissière constituée par les ailes latérales supérieure 18c et inférieure 18d. On obtient bien entendu le même résultat avec le téton en "L", qui autorise une conception plus simple, mais qui présente le risque de voir l'aile 18 de la clenche 16, par exemple en raison de vibrations, sauter et se décrocher du pied du "L", entraínant ainsi une désolidarisation accidentelle des portes 2 et 5.Said latch 16 cooperates with a stud projecting from the exterior surface of door 2 of cabin 1, which, when cabin 1 reaches the upper level, engages in the slide to lift the latch 16 out of the spar 17 and thus unlock the upper landing door 5. In the case where the main wing 18 of the latch 16 does not have a lower wing 18 d , this stud may consist of a rod, not shown in the figures, in the shape of an "L" whose leg is disposed horizontally and fixed, by its free end, perpendicular to the outer surface of door 2, so that the foot of the "L" is vertical and oriented upwards. In the context of the preferred variant shown in FIGS. 2 and 3, in which the main wing 18 of the latch 16 has a lower wing 18 d , the stud consists of a rod 19 in the shape of a "T" whose leg 19 a , arranged horizontally, is fixed, by its free end, perpendicular to the exterior surface of door 2 so that the horizontal bar 19 b of the "T" is vertical. When the cabin 1 arrives at the upper level, the upper end of the bar 19b of the "T" is inserted between the main wing 18 and the upper lateral wing 18c , on the side of the end 18 b of the latch 16, benefiting from this, the reduced length of the lower wing 18 d . The stud 19 is disposed on the door 2 of the cabin 1, so that, when said cabin 1 has reached its maximum height in the cage 3, said stud 19 has caused, in its vertical movement, the latch 16 sufficiently high, to that its end 18 b is located above the level of the sixth horizontal edge 17 f of the chin 17. The landing door 5 is thus unlocked. In addition, the length of the lower wing 18 d is such that, when the latch 16 has completed the rotational movement which has brought it into the unlocked position, the end of said lower wing 18 d is located below the 'lower end of the bar 19 b of the "T", as shown in solid lines in Figure 3 a . The stud 19 is then engaged by the two ends of the bar 19 b of its "T" in the slide formed by the upper lateral wings 18 c and lower 18 d of the latch 16. The landing door 5 and the door 2 of the cabin 1 are then secured in rotation around their respective joints, the opening or closing of one causing that of the other and vice versa. The offset between the articulations of the two doors 2 and 5 is compensated, during the operation of said doors 2 and 5 by the sliding of the bar 19b of the "T" in the slide formed by the upper side wings 18 c and lower 18 d . Obviously, the same result is obtained with the "L" nipple, which allows a simpler design, but which presents the risk of seeing the wing 18 of the latch 16, for example due to vibrations, jump and come off the foot of the "L", thus causing an accidental separation of doors 2 and 5.

En vue de la descente du niveau supérieur vers le niveau inférieur, la cabine 1 se trouvant en bonne place au niveau supérieur, et la porte palière 5 étant par conséquent déverrouillée, l'utilisateur, après avoir ouvert ladite porte palière 5, et par suite, provoqué ainsi l'ouverture de la porte 2 de la cabine 1, pénètre à l'intérieur de ladite cabine 1 qu'il ferme en tirant la porte 2, et par suite la porte palière 5. Si ladite porte 2 n'est pas suffisamment fermée, le mouvement de descente de la cabine 1 sera bloqué par appui inférieur du battant de ladite porte 2 sur le sol du niveau supérieur. Par contre, si ladite porte 2 est suffisamment fermée pour autoriser la descente de la cabine 1 mais pas assez pour permettre l'accrochage de l'extrémité 8a du bras de verrouillage 8 dans le mentonnet 12 disposé sur la face interne de la porte 2, on se trouve a priori dans une situation doublement dangereuse puisque, d'une part, la cabine 1 va pouvoir exécuter son mouvement de descente sans que sa porte 2 soit verrouillée, et d'autre part, la porte palière 5 pourra demeurer éventuellement non verrouillée, alors que la cabine 1 ne sera plus en bonne position au niveau supérieur. Pour remédier à cet inconvénient, l'inclinaison et la longueur de la rampe oblique constituée par le cinquième bord 17e du mentonnet 17 ainsi que la longueur du téton 19 sont déterminées de sorte que, dès que la position de la porte 2 autorise le mouvement de descente de la cabine 1, c'est à dire dès que son battant ne dépasse plus au-dessus du sol du niveau supérieur, l'extrémité 18b de la clenche 16 se situe au moins à la verticale de la partie haute de ladite rampe. Ainsi, lors de la descente de la cabine 1, la clenche 16 qui va descendre tout d'abord entraínée par le téton 19, puis, lorsque la barre 19b du "T" ne portera plus sur l'aile latérale inférieure 18d qui se sera effacée par rotation, entraínée par son seul poids, va glisser le long de ladite rampe et venir se placer, par son extrémité 18b dans la fente verticale du mentonnet 17, assurant ainsi le verrouillage et la fermeture complète de la porte palière 5, par rotation de cette dernière autour de son articulation. De plus, ce mouvement de rotation est communiqué par la porte palière 5 à la porte 2 par l'intermédiaire du téton 19, permettant ainsi la fermeture complète de ladite porte 2, et ce, avant que le bras de verrouillage 8 n'ait terminé son mouvement d'abaissement entraíné par la coopération de la face postérieure 10b de sa came 10 avec l'extrémité supérieure 11a de la butée 11, assurant ainsi le verrouillage de la porte 2 par accrochage de l'extrémité libre 8a dans le mentonnet 12. L'ordre chronologique d'occurrence des différentes phases pourra, par exemple, être obtenu grâce au profil adapté de la came 10. De même, comme il a déjà été dit ci-avant, la longueur de l'aile inférieure 18d est choisie de façon à ce que, lorsque la clenche 16 se trouve au fond de la fente verticale du mentonnet 17, le téton 19 soit libre de poursuivre son mouvement de translation vers le bas. Enfin, l'utilisation de la rampe oblique du mentonnet 17 permet aussi, selon le même mécanisme, d'assurer la fermeture complète et le verrouillage de la porte palière 5 lorsque la fermeture complète de la porte 2 ne suffit pas à les obtenir, en raison, par exemple, du jeu fonctionnel existant entre le téton 19 et la clenche 16. On obtient des résultats semblables avec le téton en "L" et la clenche 16 dépourvue d'aile latérale inférieure 18d, la descente de ladite clenche 16 étant alors provoquée par son seul poids. Néanmoins, les risques de décrochage et donc, de désolidarisation accidentels des deux portes 2,5 sont plus importants.In view of the descent from the upper level to the lower level, the cabin 1 being in a good place at the upper level, and the landing door 5 being consequently unlocked, the user, after having opened said landing door 5, and consequently , thus caused the opening of door 2 of cabin 1, enters inside said cabin 1 which it closes by pulling door 2, and consequently the landing door 5. If said door 2 is not sufficiently closed, the downward movement of the cabin 1 will be blocked by lower pressing of the leaf of said door 2 on the floor of the upper level. By cons if said door 2 is sufficiently closed to allow the descent of the cabin 1 but not enough to allow the hooking of the end 8 a of the lock arm 8 in the flange 12 disposed on the inner face of the door 2 , we are a priori in a doubly dangerous situation since, on the one hand, the cabin 1 will be able to execute its downward movement without its door 2 being locked, and on the other hand, the landing door 5 may possibly remain non locked, while cabin 1 will no longer be in a good position on the upper level. To remedy this drawback, the inclination and the length of the oblique ramp formed by the fifth edge 17 e of the chin 17 as well as the length of the stud 19 are determined so that, as soon as the position of the door 2 authorizes the movement lowering cabin 1, that is to say as soon as its leaf no longer exceeds above the ground of the upper level, the end 18 b of the latch 16 is located at least vertically from the upper part of said ramp. Thus, during the descent of the car 1, the latch 16 will descend initially driven by the pin 19, then, when the bar 19 b of the "T" will further on the lower side flange 18 of which will be erased by rotation, driven by its only weight, will slide along said ramp and come to be placed, by its end 18 b in the vertical slot of the chin 17, thus ensuring the locking and complete closing of the landing door 5 , by rotation of the latter around its articulation. In addition, this rotational movement is communicated by the landing door 5 to the door 2 by means of the stud 19, thus allowing the complete closure of said door 2, before the locking arm 8 has finished. its lowering movement driven by cooperation of the rear face 10 b of the cam 10 with the upper end 11a of the stop 11, thus ensuring the locking of the door 2 by gripping the free end 8a in the jib 12. The chronological order of occurrence of the different phases could, for example, be obtained thanks to the adapted profile of the cam 10. Likewise, as has already been said above, the length of the lower wing 18 d is chosen so that, when the latch 16 is at the bottom of the vertical slot of the chin 17, the stud 19 is free to continue its downward translation movement. Finally, the use of the oblique ramp of the chin 17 also allows, according to the same mechanism, to ensure complete closure and locking of the landing door 5 when the complete closure of the door 2 is not sufficient to obtain them, reason, for example, of the functional clearance existing between the stud 19 and the latch 16. Similar results are obtained with the "L" stud and the latch 16 devoid of lower lateral wing 18 d , the descent of said latch 16 being then caused by its weight alone. However, the risks of stalling and therefore of accidental detachment of the two doors 2.5 are greater.

Selon une variante particulière représentée sur les figures 2 et 5, l'élévateur selon l'invention possède au niveau inférieur, une cage 3' fermée par une porte palière 5' à battant, normalement verrouillée, s'ouvrant vers l'extérieur de la cabine 1 selon une articulation disposée du même coté que celle de la porte 2 de la cabine 1. Il est alors muni de moyens permettant, à l'instar de ceux existant sur la porte palière 5 supérieure :

  • de solidariser automatiquement en rotation autour de leur articulation respective la porte 2 de la cabine 1 et la porte palière 5' inférieure lorsque la cabine 1 atteint le niveau inférieur,
  • de désolidariser automatiquement la porte 2 de la cabine 1 et la porte palière 5' inférieure lorsque la cabine 1 quitte le niveau inférieur,
  • de procurer, sur mouvement descendant de la cabine 1, le déverrouillage automatique de la porte palière 5' inférieure lorsque la cabine 1 atteint le niveau inférieur,
  • de procurer automatiquement, sur mouvement ascendant de la cabine 1 quittant le niveau inférieur, la fermeture complète de la porte palière 5' et de la porte 2 de la cabine 1 et, simultanément, le verrouillage desdites portes 2,5', le battant de ladite porte 2 ayant été, préalablement, suffisamment tiré pour permettre la montée de la cabine 1.
    • According to a particular variant shown in Figures 2 and 5, the elevator according to the invention has at the lower level, a cage 3 'closed by a landing door 5' swing, normally locked, opening towards the outside of the cabin 1 according to an articulation arranged on the same side as that of door 2 of cabin 1. It is then provided with means making it possible, like those existing on the upper landing door 5:
  • to automatically secure in rotation around their respective articulation the door 2 of the cabin 1 and the lower landing door 5 ′ when the cabin 1 reaches the lower level,
  • to automatically separate the door 2 from the cabin 1 and the lower landing door 5 'when the cabin 1 leaves the lower level,
  • to provide, on downward movement of cabin 1, automatic unlocking of the lower landing door 5 ′ when cabin 1 reaches the lower level,
  • to automatically provide, on upward movement of the cabin 1 leaving the lower level, the complete closing of the landing door 5 'and of the door 2 of the cabin 1 and, simultaneously, the locking of said doors 2.5', the leaf of said door 2 having been previously pulled enough to allow the cabin 1 to climb.

    • Bien entendu lesdits moyens sont ici encore tous de type passif et entièrement mécanique, consistant en une coopération du téton 19 avec une coulisse, montée pivotante dans le plan de la porte palière 5' inférieure, du côté de la cabine 1, pour constituer une clenche 16' venant verrouiller ladite porte palière 5' dans un mentonnet 17' solidaire du garde-corps 4' et situé à l'opposé de l'articulation de ladite porte palière 5'.Of course, the said means are here again all passive and fully mechanical type, consisting of cooperation of the nipple 19 with a slide, pivotally mounted in the plane of the lower landing door 5 ', on the side of the cabin 1, to constitute a latch 16 'coming to lock said landing door 5 'in a chin 17' integral with the railing 4 'and located opposite the articulation of said landing door 5 '.

    La clenche 16' inférieure et le mentonnet 17' sont les symétriques de la clenche 16 et du mentonnet 17 par rapport à un plan horizontal situé à mi-hauteur entre les niveaux inférieur et supérieur. La clenche 16' est donc, par exemple, constituée par un profilé de section en "L" constitué d'une aile principale 18' montée à rotation par une de ses extrémités 18'a dans le plan de la porte palière 5' autour d'un axe perpendiculaire à ladite porte 5' et coopérant par son autre extrémité 18'b, avec le mentonnet 17' de la porte palière 5'. L'aile principale 18' est bordée sur sa longueur par une aile latérale inférieure 18'd s'étendant d'abord perpendiculairement à ladite aile principale 18' en direction de la cabine 1 puis ensuite parallèlement et le long de l'aile principale 18', de façon à former une glissière. Selon une autre variante préférentielle représentée sur la figure 5, la clenche 16' est constituée par un profilé de section en "C" constitué de l'aile principale 18' précédente bordée sur sa longueur par une deuxième aile latérale supérieure 18'c. Les deux ailes latérales supérieure 18'c et inférieure 18'd s'étendent d'abord perpendiculairement à ladite aile principale 18' en direction de la cabine 1 puis ensuite en direction l'une de l'autre, parallèlement à l'aile principale 18', de façon à former une glissière, l'aile latérale inférieure 18'd dépassant, du côté de l'extrémité coopérant avec le mentonnet 17', par rapport à l'aile latérale supérieure 18'c.The lower latch 16 ′ and the flange 17 ′ are the symmetrics of the latch 16 and the flange 17 with respect to a horizontal plane situated halfway between the lower and upper levels. The latch 16 'is therefore, for example, constituted by a sectional section in "L" consisting of a main wing 18' rotatably mounted by one of its ends 18 ' has in the plane of the landing door 5' around d 'an axis perpendicular to said door 5' and cooperating at its other end 18 ' b , with the chin 17' of the landing door 5 '. The main wing 18 'is bordered along its length by a lower lateral wing 18' d extending first perpendicularly to said main wing 18 'in the direction of the cabin 1 then then parallel and along the main wing 18 ', so as to form a slide. According to another preferred variant shown in FIG. 5, the latch 16 ′ is constituted by a sectional section in “C” consisting of the preceding main wing 18 ′ bordered along its length by a second upper lateral wing 18 ′ c . The two upper side wings 18 ′ c and lower 18 ′ d extend first perpendicularly to said main wing 18 ′ in the direction of cabin 1 and then in the direction of one another, parallel to the main wing 18 ', so as to form a slide, the lower lateral wing 18' d projecting, on the side of the end cooperating with the chin 17 ', relative to the upper lateral wing 18' c .

    De même, ledit mentonnet 17' consiste en une découpe pratiquée dans l'épaisseur du garde-corps 4', débouchant à l'opposé de la cabine 1 et délimitée par un premier bord 17'a horizontal, prolongé, vers le haut et du côté de la cabine 1, par un deuxième bord 17'b vertical, lui-même prolongé vers l'extérieur de la cabine 1 par un troisième bord 17'c horizontal, lui-même prolongé vers le bas par un quatrième bord 17'd vertical, lui-même prolongé vers le bas et vers l'extérieur de la cabine 1 par un cinquième bord 17'e constituant une rampe oblique et se prolongeant par un sixième bord 17'f vertical se terminant à la verticale de l'origine du premier bord 17a, et à une distance de ce premier bord 17a supérieure à la largeur de l'aile principale 18' de la clenche 16'. Le deuxième bord 17'b vertical, le troisième bord 17'c horizontal et le quatrième bord 17'd vertical définissent une fente verticale destinée à recevoir l'extrémité 18'b de la clenche 16' qui, lorsqu'elle s'y trouve engagée à fond, est inclinée en contre-haut de son axe d'articulation perpendiculairement à la porte palière 5'. La clenche 16' est, à cet effet, prolongée, au-delà de son axe de rotation, par un contrepoids 20 assurant son inclinaison en contre-haut de son axe d'articulation et par suite, le verrouillage de la porte palière 5' inférieure lorsque le téton 19 n'est pas engagé dans la glissière de ladite porte 5'. Un tel dispositif est représenté sur la figure 5. Tout autre moyen équivalent, assurant le verrouillage de la clenche 16', tel un ressort, ne sortirait bien évidemment pas du cadre de l'invention. Selon une variante minimale assurant un bon fonctionnement, non représentée sur les figures, le mentonnet 17' comporte uniquement le quatrième bord 17'd vertical et le cinquième bord 17'e constituant la rampe oblique. L'arrêt en rotation de la porte palière 5' n'est plus alors réalisé par l'intermédiaire de la clenche 16', mais par un couvre-joint, disposé le long du bord vertical extérieur du battant de la porte palière 5' et qui vient prendre appui sur le garde-corps 4'. De même, l'arrêt en rotation de la clenche 16' est alors réalisé par une butée prévue sur la porte palière 5'.Likewise, said spar 17 ′ consists of a cutout made in the thickness of the railing 4 ′, opening opposite the cabin 1 and delimited by a first edge 17 ′ a horizontal, extended, upward and side of cabin 1, by a second vertical edge 17 ' b , itself extended towards the outside of cabin 1 by a third horizontal edge 17' c , itself extended downwards by a fourth edge 17 ' d vertical, itself extended downwards and towards the outside of the cabin 1 by a fifth edge 17 ' e constituting an oblique ramp and extending by a sixth edge 17' f vertical ending at the vertical of the origin of the first edge 17 a, and a distance from the first edge 17 is greater than the width of the main wing 18 'of the latch 16'. The second edge 17 ' b vertical, the third edge 17' c horizontal and the fourth edge 17 ' d vertical define a vertical slot intended to receive the end 18' b of the latch 16 'which, when it is there fully engaged, is inclined against the top of its hinge axis perpendicular to the landing door 5 '. The latch 16 ′ is, for this purpose, extended, beyond its axis of rotation, by a counterweight 20 ensuring its inclination against the top of its articulation axis and consequently, the locking of the landing door 5 ′ lower when the stud 19 is not engaged in the slide of said door 5 '. Such a device is shown in Figure 5. Any other equivalent means, ensuring the locking of the latch 16 ', such as a spring, would obviously not depart from the scope of the invention. According to a minimum variant ensuring proper operation, not shown in the figures, the jib 17 'has only the fourth edge 17' d vertical and the fifth edge 17 ' e constituting the oblique ramp. The stop in rotation of the landing door 5 ′ is no longer carried out by means of the latch 16 ′, but by a joint cover, disposed along the outer vertical edge of the leaf of the landing door 5 ′ and which comes to rest on the railing 4 '. Similarly, the stop in rotation of the latch 16 'is then achieved by a stop provided on the landing door 5'.

    Le fonctionnement décrit ci-dessus, pour la porte palière 5 du niveau supérieur, vaut bien entendu encore pour la porte palière inférieure 5', à la condition d'inverser le sens des mouvements. Cette variante dans laquelle on dispose d'une cage 3' au niveau inférieur présente l'avantage d'interdire strictement tout mouvement ascendant de la cabine 1, lorsque la porte 2 est ouverte, car le haut de son battant vient alors en appui sur le haut de la partie du garde-corps 4'. Il n'est donc pas nécessaire de disposer un arceau au dessus de la zone d'ouverture du battant de la porte 2.The operation described above, for the door level 5 of the upper level, of course also applies to the lower landing door 5 ', on the condition of reversing the sense of movement. This variant in which we have a 3 'cage on the lower level has the advantage to strictly prohibit any upward movement of the cabin 1, when door 2 is open, because the top of its flap then comes to rest on the top of the part of the railing 4 '. It is therefore not necessary to have a hoop above the leaf opening area of the door 2.

    Cette variante nécessite néanmoins un aménagement supplémentaire sous la forme d'un marchepied 21, représenté sur la figure 2, solidaire du niveau supérieur et présentant une découpe 22 autorisant le passage du téton 19 prévu sur la porte 2 de la cabine 1. En effet, dans le cas où seul le niveau supérieur présente une cage 3, il est possible de disposer la porte 2 en retrait du plancher 6 de la cabine 1, et avec elle, le téton 19. Il suffit alors que la clenche 16 dépasse au delà de la limite du sol du niveau supérieur, au dessus de la partie du plancher 6 dépassant de la porte 2, pour pouvoir coopérer avec le téton 19. Cette disposition qui présente l'avantage de pouvoir faire affleurer le plancher 6 et le sol du niveau supérieur, n'est cependant plus possible lorsque l'on utilise une porte palière 5' inférieure, car le plancher 6 de la cabine 1 viendrait en contact avec la clenche 16' inférieure lors de la descente de la cabine 1. C'est pourquoi le plancher 6 de la cabine 1 s'arrête au ras de la porte 2 de ladite cabine 1. On comble alors l'espace entre ledit plancher 6 de la cabine 1, en bonne position au niveau supérieur, et le sol du niveau supérieur par un marchepied 21.This variant nevertheless requires an arrangement additional in the form of a step 21, shown in Figure 2, integral with the upper level and having a cutout 22 authorizing the passage of the stud 19 provided on the door 2 of cabin 1. Indeed, in the case where only the upper level has a cage 3, it is possible to place the door 2 set back from the floor 6 of the cabin 1, and with it, the nipple 19. It then suffices that the latch 16 exceeds beyond the upper limit of the ground, at above the part of the floor 6 projecting from the door 2, to be able to cooperate with the nipple 19. This provision which has the advantage of being able to flush the floor 6 and the upper level floor, however, is no longer possible when using a lower landing door 5 ', because the floor 6 of cabin 1 would come into contact with the 16 'lower latch when lowering cabin 1. This is why the floor 6 of cabin 1 stops flush of door 2 of said cabin 1. We then fill the space between said floor 6 of cabin 1, in good position at upper level, and the upper level floor by a step 21.

    Enfin, dans le cas où, pour des raisons de disposition du lieu d'implantation de l'élévateur, l'accès à la cabine 1 n'est pas possible sur la même face de ladite cabine 1 aux niveaux inférieur et supérieur, on peut très bien, selon une variante non représentée sur les figures, remplacer une des parois latérales 9,15 par une seconde porte de cabine 1. Cette seconde porte présentera également un mentonnet sur la face intérieure de son battant, dans lequel viendra se loger, non plus, l'extrémité 8a ou 8'a du bras de verrouillage 8 ou 8', mais le bras de verrouillage 8 ou 8' lui-même. Chacune des deux portes de cabine pourra être munie d'un téton et coopérer avec sa porte palière respective, lesdites portes palières 5 et 5' n'étant plus situées l'une en dessous de l'autre.Finally, in the case where, for reasons of arrangement of the location of the elevator, access to cabin 1 is not possible on the same face of said cabin 1 at the lower and upper levels, it is possible to very well, according to a variant not shown in the figures, replace one of the side walls 9,15 with a second cabin door 1. This second door will also have a stud on the inside of its leaf, in which will be accommodated, not Moreover, the end 8 a or 8 'has the locking arm 8 or 8', but the locking arm 8 or 8 'itself. Each of the two cabin doors may be provided with a stud and cooperate with its respective landing door, said landing doors 5 and 5 'no longer being located one below the other.
