Estructura de puerta para un ascensor.Door structure for an elevator.

       \global\parskip0.900000\baselineskip\ global \ parskip0.900000 \ baselineskip
    

El invento trata de una estructura de puerta para un ascensor, concretamente de una puerta de una cabina de ascensor o para una puerta de un hueco de ascensor, según el término genérico de la reivindicación 1.The invention is about a door structure for an elevator, specifically a door of a cabin of elevator or for a door of an elevator shaft, according to the term generic of claim 1.

En las suspensiones de puerta de este tipo, visto en sección están dispuestas, fundamentalmente, suspensiones en forma de C, que se sujetan en los rieles. Esto tiene la ventaja de que las puertas pueden colgarse y descolgarse con facilidad, lo que es especialmente conveniente, si en la puerta están instalados componentes que deben ser conectados mediante cables eléctricos. Sin embargo, resulta desfavorable que las suspensiones deban conducirse con una distancia adecuada encima de ambos rieles, de modo que los rieles deben tener una distancia adecuada respecto al hueco de ascensor (en el caso de puertas de ascensor) o bien respecto a la cabina (en el caso de puertas de hueco de ascensor). De este modo resulta, sin embargo, una profundidad respectivamente mayor de toda la estructura, a expensas del espacio interior de la cabina. Especialmente, resulta un problema en la instalación posterior de puertas interiores en las que las dimensiones interiores ya no pueden modificarse.In door hangers of this type, seen in section are arranged, essentially, suspensions C-shaped, which are fastened on the rails. This has the advantage. that the doors can be hung up and down easily, which is especially convenient, if they are installed on the door components that must be connected by electric cables. However, it is unfavorable that suspensions should drive with adequate distance on both rails, of so that the rails must have an adequate distance from the elevator shaft (in the case of elevator doors) or with respect to the cabin (in the case of elevator shaft doors). This results in a depth, however, respectively. greater of the entire structure, at the expense of the interior space of the cabin. Especially, it is a problem in the installation rear interior doors in which the dimensions Interiors can no longer be modified.

Por los documentos US 5 878 846 A y US 2005/296038 se conocen suspensiones de puertas en las que, si bien las suspensiones de puertas alejadas del hueco de ascensor corren en el espacio entre los rieles de guía, las suspensiones de las puertas cercanas al hueco de ascensor están realizadas, sin embargo, igual que antes como suspensiones acodadas que se sujetan de su lado del hueco de ascensor al riel de guía y, en consecuencia, crecen en profundidad en forma correspondiente.For documents US 5 878 846 A and US 2005/296038 door suspensions are known in which, although door suspensions away from the elevator shaft run in the space between the guide rails, the suspensions of the doors near the elevator shaft are made, however, as before as layered suspensions that are attached to your side of the elevator shaft to the guide rail and, consequently, they grow in depth correspondingly.

Es el objetivo del invento, evitar dichas desventajas y proponer una suspensión de puerta del tipo mencionado al comienzo, que se destaca por su escasa profundidad.It is the objective of the invention, to avoid said disadvantages and propose a door suspension of the type mentioned At the beginning, it stands out for its low depth.

De conformidad con el invento, ello se consigue en una suspensión de puerta del tipo mencionado al comienzo mediante la parte caracterizante de las características de la reivindicación 1.In accordance with the invention, this is achieved. on a door hanger of the type mentioned at the beginning through the characterizing part of the characteristics of the claim 1.

Mediante las medidas propuestas, resultan suspensiones de diseño muy sencillo, en las que al colgar los segmentos de puerta no se producen desviaciones de una posición perpendicular dignas de mención. Las suspensiones conectadas con los segmentos de puertas pueden fabricarse muy sencillamente de una chapa plana, sin que se la deba acodar repetidas veces, como es el caso en las soluciones conocidas. Como no se presentan otras fuerzas de flexión, las suspensiones pueden fabricarse de chapa fina apropiada. Sin embargo, la construcción propuesta se destaca especialmente por su escasa profundidad.Through the proposed measures, they result very simple design suspensions, in which when hanging the Door segments do not produce deviations from one position perpendicular worth mentioning. The suspensions connected with the door segments can be manufactured very simply from one flat sheet, without being repeatedly layered, as is the Case in known solutions. How others are not presented bending forces, the suspensions can be made of thin sheet appropriate. However, the proposed construction stands out especially for its low depth.

Generalmente, están dispuestos dos grupos de segmentos de puerta: Los segmentos de cada grupo abren en forma telescópica y se mueven siempre en forma colectiva en la misma dirección. Frecuentemente, en razón del espacio es necesario conformar los segmentos de puerta de un grupo de anchura diferente respecto a los segmentos de puerta del otro grupo. En este caso, el accionamiento de ambos grupos puede ser problemático, porque ambos grupos deben accionarse a diferente velocidad si se quiere que los segmentos de puerta de ambos grupos abran al mismo tiempo. Dentro de cada grupo, los segmentos de puerta están acoplados entre sí de forma que interactúan en movimiento, de modo que solamente es necesario accionar un segmento de puerta (normalmente el más rápido).Generally, two groups of Door segments: The segments of each group open in shape telescopic and always move collectively in it address. Frequently, because of space it is necessary form the door segments of a group of different width with respect to the door segments of the other group. In this case, the driving both groups can be problematic, because both groups must be operated at different speeds if you want the Door segments of both groups open at the same time. Inside of each group, the door segments are coupled to each other in so that they interact in motion, so that it is only necessary to operate a door segment (usually the most Quick).

En consecuencia, en dicha conformación se dispone que, preferentemente, ambos grupos de segmentos de puertas sean accionados mediante un accionamiento común a través de una polea escalonada. De este modo, no es necesaria una desmultiplicación costosa y no existe una necesidad de espacio en la dirección normal al plano de los segmentos de puerta.Consequently, in said conformation provides that, preferably, both groups of door segments are driven by a common drive through a stepped pulley. Thus, a expensive demultiplication and there is no need for space in the normal direction to the plane of the door segments.

A continuación, el invento se explica en detalle mediante los dibujos. Muestran: La figura 1, una representación axonométrica esquematizada de las suspensiones de segmentos de puerta, según el invento; y la figura 2, una vista esquematizada de las suspensiones, según la figura 1.Next, the invention is explained in detail. through the drawings They show: Figure 1, a representation axonometric schematics of the suspensions of segments of door, according to the invention; and Figure 2, a schematic view of the suspensions, according to figure 1.

El invento se explica en base a una puerta de cabina de ascensor, pero también puede aplicarse a una puerta de hueco de ascensor. Están dispuestos dos grupos de segmentos de puerta, comprendiendo un grupo ambos segmentos izquierdos 20 y 21 (como se ve en la figura 2) y el otro grupo ambos segmentos derechos 20', 21' (como se ve en la figura 2) . Los segmentos 20, 21 de un grupo abren hacia la izquierda (como se ve en la figura 2), los segmentos 20', 21' del otro grupo abren hacia la derecha (como se ve en la figura 2). Dentro de un grupo, ambos segmentos de puerta 20, 21 ó 20', 21' se desplazan en forma telescópica, uno delante del otro. Los segmentos de puerta derechos 20', 21' son más estrechos que los segmentos de puerta izquierdos 20, 21.The invention is explained based on a door of elevator car, but can also be applied to a door elevator shaft Two groups of segments of door, comprising a group both left segments 20 and 21 (as seen in figure 2) and the other group both right segments 20 ', 21' (as seen in Figure 2). Segments 20, 21 of a group open to the left (as seen in figure 2), the segments 20 ', 21' of the other group open to the right (as seen in figure 2). Within a group, both door segments 20, 21 or 20 ', 21' move telescopically, one in front of the other. The right door segments 20 ', 21' are narrower than the left door segments 20, 21.

En un soporte 1, montado en una cabina de ascensor (no mostrada), están fijados dos rieles 2, 2'. En este caso, ambos rieles 2, 2' se extienden paralelos entre sí y en dirección horizontal. Los rieles 2, 2' están sujetados por medio de pernos 3, determinando éstos también la distancia entre el soporte 1 y el riel 2 y, de este modo, un intersticio 4. El intersticio 5 entre ambos rieles 2, 2' también es determinado por los pernos 3.On a stand 1, mounted in a cab elevator (not shown), two 2, 2 'rails are fixed. In this case, both rails 2, 2 'extend parallel to each other and in horizontal direction The 2, 2 'rails are held by bolts 3, these also determining the distance between the support 1 and rail 2 and, thus, an interstitium 4. The interstitium 5 between both rails 2, 2 'is also determined by bolts 3.

El intersticio 4 entre el riel 2 y el soporte 1 es atravesado por suspensiones 6, 6' unidas a segmentos de puerta (del lado del borde) 20, 20' y sujeta los mismos. En este caso, los segmentos de puerta 20, 20' y las suspensiones 6, 6' respectivas presentan anchuras diferentes.The gap 4 between rail 2 and bracket 1 it is crossed by suspensions 6, 6 'attached to door segments (on the edge side) 20, 20 'and hold them. In this case, the door segments 20, 20 'and the respective suspensions 6, 6' They have different widths.

       \global\parskip1.000000\baselineskip\ global \ parskip1.000000 \ baselineskip
    

En estas suspensiones 6, 6' se sujetan en cada una cuatro rodillos 7 que ruedan sobre el lado superior e inferior del riel 2. Los rodillos superiores son denominados rodillos de suspensión, porque en ellos se suspende el segmento de puerta respectivo. Los rodillos inferiores se denominan contrarodillos, porque evitan que los segmentos de puerta puedan ser desenganchados. En vez de los rodillos 7 también pueden usarse elementos deslizantes.In these suspensions 6, 6 'are held in each a four rollers 7 that roll on the upper and lower side of the rail 2. The upper rollers are called rollers of suspension, because the door segment is suspended in them respective. The lower rollers are called counter rollers, because they prevent the door segments from being unhooked Instead of rollers 7 they can also be used sliding elements

El intersticio 5 entre ambos rieles 2, 2' es atravesado por suspensiones 8, 8' unidas a segmentos de puerta (medios) 21, 21' y sujeta los mismos. En las suspensiones 8, 8' se sujetan, del mismo modo, en cada una cuatro rodillos 7 que ruedan en el riel 2'. Además, en las suspensiones 6, 6', 8, 8' están dispuestas palancas 9 que interactúan con patines 10 y forman en conjunto un acoplador para puertas de hueco de ascensor, pero no son parte del invento. La puerta de hueco de ascensor se arrastra por medio de este acoplador cuando abre la puerta de cabina, de modo que las puertas de hueco de ascensor no requieren accionamiento propio. La puerta de hueco de ascensor está dotada de un enclavamiento, que evita una apertura cuando la cabina no se encuentra detrás de la puerta de hueco de ascensor. Tampoco este enclavamiento es parte del invento.The gap 5 between both rails 2, 2 'is crossed by suspensions 8, 8 'attached to door segments (means) 21, 21 'and holds the same. In suspensions 8, 8 'is they hold, in the same way, on each four rollers 7 that roll on the 2 'rail. In addition, in suspensions 6, 6 ', 8, 8' are arranged levers 9 that interact with skates 10 and form in set a coupler for elevator shaft doors, but not They are part of the invention. The elevator shaft door crawls by means of this coupler when you open the cabin door, of so that elevator shaft doors do not require actuation own. The elevator shaft door is equipped with a interlocking, which prevents an opening when the cabin is not It is located behind the elevator shaft door. Neither this interlocking is part of the invention.

Como puede verse claramente en la figura 1, casi no se necesita lugar delante del riel 2', solamente sobresalen algo las cabezas de los pernos 3. Ello se consigue, porque las suspensiones 8, 8' y 6, 6' atraviesan ambos intersticios 4, 5 y no se sujetan a los rieles 2, 2'.As can be clearly seen in Figure 1, almost no place is needed in front of the 2 'rail, just stick out something the bolt heads 3. This is achieved, because the suspensions 8, 8 'and 6, 6' cross both interstices 4, 5 and not are attached to the 2, 2 'rails.

Como puede verse especialmente en la figura 2, la suspensión 8', prevista para el segmento de puerta más estrecho 21', presenta un saliente 11 en cuya región están dispuestos dos rodillos 7. De este modo, dichos rodillos 7 de la suspensión 8' presentan una mayor distancia que lo que sería posible sin el saliente 11. Con ello, se consigue una mejor guía del segmento de puerta 21'. La suspensión 8, que tal como la suspensión 8' atraviesa el intersticio 5 entre los rieles 2' y está prevista para un segmento de puerta más ancho 21, presenta una escotadura 12 para procurar lugar para el saliente 11.As can be seen especially in Figure 2, 8 'suspension, intended for the narrowest door segment 21 ', has a projection 11 in whose region two are arranged rollers 7. Thus, said rollers 7 of the suspension 8 ' they have a greater distance than would be possible without the outgoing 11. With this, you get a better guide to the segment of door 21 '. The suspension 8, which such as the suspension 8 ' it crosses the gap 5 between the rails 2 'and is planned to a wider door segment 21, has a recess 12 for procure space for the outgoing 11.

El accionamiento de ambos segmentos de puerta 20, 21 y 20', 21' de cada grupo se realiza, generalmente, de tal modo que el segmento de puerta intermedio 21, 21' es accionado activamente y el segmento de puerta del lado del borde 20, 20' es arrastrado por el segmento de puerta medio 21, 21' mediante una desmultiplicación en relación 2:1.The drive of both door segments 20, 21 and 20 ', 21' of each group is generally made of such so that the intermediate door segment 21, 21 'is driven actively and the edge side door segment 20, 20 'is dragged by the middle door segment 21, 21 'by a demultiplication in a 2: 1 ratio.

Ahora, cuando los segmentos de puerta 20, 21 y 20', 21' de ambos grupos tienen anchuras diferentes, ambos segmentos de puerta medios 21, 21' deben, naturalmente, ser accionados a velocidad diferente si se quiere que el movimiento de apertura de ambos grupos dure lo mismo. Cuando la anchura se comporta como 1:2, el segmento de puerta medio 21' más estrecho podría ser accionado por el segmento de puerta del lado de borde 20 más ancho. Sin embargo, ello requeriría un espacio adicional que, precisamente, según el invento se pretende economizar.Now, when the door segments 20, 21 and 20 ', 21' of both groups have different widths, both middle door segments 21, 21 'must, of course, be operated at a different speed if you want the movement of Opening of both groups last the same. When the width is It behaves like 1: 2, the 21 'narrowest middle door segment could be operated by the edge segment door edge 20 wider. However, this would require an additional space that, precisely, according to the invention it is intended to economize.

Por consiguiente, es preferente un motor de accionamiento 13, que acciona un engranaje en forma de polea escalonada 14 (véase la figura 2). En este caso, la polea escalonada 14 puede estar conformada como polea de transmisión escalonada, que mediante dos correas 15, 16, conducidas a través de poleas inversoras 17, que accionan los segmentos de puerta medios 21, 21' a través de las suspensiones 8, 8' unidas con las correas 15, 16. Dichas suspensiones 8, 8' están acopladas entre sí de forma que interactúan en movimiento con las suspensiones 6, 6'. De este modo, con un accionamiento de las correas 15, 16 las suspensiones 8, 8' son movidas y las suspensiones 6', 6 arrastradas, por ejemplo, por medio de un arrastre convencional (no mostrado), por ejemplo, en la forma de un cable.Therefore, a motor of preference is preferred drive 13, which drives a pulley-shaped gear staggered 14 (see figure 2). In this case, the stepped pulley 14 may be shaped as a stepped drive pulley, which by two belts 15, 16, driven through pulleys inverters 17, which drive the middle door segments 21, 21 ' through the suspensions 8, 8 'connected with the belts 15, 16. Said suspensions 8, 8 'are coupled together so that interact in motion with suspensions 6, 6 '. In this way, with a drive of the belts 15, 16 the suspensions 8, 8 ' they are moved and the suspensions 6 ', 6 dragged, for example, by means of a conventional drag (not shown), for example, in the shape of a cable.

Generalmente, un accionamiento de este tipo es necesario solamente en la puerta de cabina. La puerta de hueco de ascensor es movida transfiriendo el movimiento de la puerta de cabina a la puerta de hueco de ascensor por medio de un acoplador.Generally, such a drive is necessary only at the cabin door. The hollow door of elevator is moved by transferring the movement of the door of cabin at the elevator shaft door by means of a coupler.
