"Un operador y un sistema de apertura y cierre de una puerta plegable de cabina de ascensor de dos o más hojas articuladas tipo bus" "An operator and an opening and closing system for a folding elevator car door with two or more bus-type articulated blades"
Sector técnico de la invención Technical sector of the invention
La invención se refiere al ámbito de los ascensores y más concretamente a un operador del movimiento entre una posición cerrada y una posición abierta de una puerta plegable de cabina de ascensor de dos o más hojas articuladas que se abaten en su apertura comprimiéndose a modo de acordeón, es decir, de una puerta tipo bus. La invención también se refiere a un sistema de apertura y cierre de una puerta tipo bus que comprende dicho operador. The invention relates to the field of elevators and more specifically to an operator of the movement between a closed position and an open position of a folding elevator car door with two or more articulated blades that are folded in their opening and compressed as an accordion. , that is, of a bus type door. The invention also relates to an opening and closing system of a bus type door comprising said operator.
Antecedentes de la invención Background of the invention
En la actualidad se conocen diversos operadores de cabina para puertas tipo bus, es decir, puertas plegables, divididas en dos o más hojas que al abrirse se articulan entre sí comprimiéndose la puerta a modo de acordeón, muy utilizadas en casos de modernizaciones de elevadores existentes o instalaciones de nuevos ascensores en huecos reducidos, donde no existe el espacio requerido para albergar las hojas de la puerta en posición de apertura. At present, several cab operators are known for bus-type doors, that is, folding doors, divided into two or more sheets that, when opened, articulate with each other, compressing the door as an accordion, widely used in cases of modernization of existing elevators or installations of new elevators in small gaps, where there is no space required to house the door leaves in the open position.
A lo largo del tiempo se han hecho intentos para reducir el espacio necesario para albergar el operador de cabina, introduciendo dentro de un chasis con forma de caja colocado sobre el dintel de la cabina algunos de los elementos de transmisión de los movimientos de apertura y cierre desde el motor a las hojas de la puerta. Se ha conseguido ubicar el grupo motor, formado por un motor cuyo eje está acoplado a un grupo reductor o transmisor dentro de la caja, de modo que el eje de salida del grupo motor, dispuesto en posición vertical, atraviesa la cara superior del chasis y su giro se convierte en un movimiento de traslación de dos bielas ubicadas por encima del chasis y que mediante una serie de mecanismos convierten dicho movimiento en un movimiento de rotación de dos ejes alineados con los ejes de las puertas situados en los extremos del dintel. Pese a poder ubicar el grupo motor y otros componentes dentro del chasis en forma de caja, el eje de salida del grupo motor, los conjuntos de biela-
manivela y los mecanismos asociados a las mismas siguen necesitando un espacio adicional por encima del chasis. Over time, attempts have been made to reduce the space needed to house the cabin operator, by introducing some of the transmission elements of the opening and closing movements into a box-shaped chassis placed on the cabin lintel. from the engine to the door leaves. It has been possible to locate the motor group, formed by a motor whose axis is coupled to a reduction or transmitter group inside the box, so that the output axis of the motor group, arranged in an upright position, crosses the upper face of the chassis and its rotation becomes a movement of translation of two connecting rods located above the chassis and that by means of a series of mechanisms converts said movement into a movement of rotation of two axes aligned with the axes of the doors located at the ends of the lintel. Despite being able to locate the engine group and other components inside the box-shaped chassis, the output shaft of the engine group, the connecting rod assemblies. crank and the mechanisms associated with them still need additional space above the chassis.
Además, los operadores conocidos hasta la fecha incluyen sistemas de transmisión complejos mediante poleas de reducción, cadenas o correas, que aunque estén situados dentro del chasis, incrementan el coste total del operador y por tanto, dificultan y encarecen las operaciones de mantenimiento del ascensor. Es por lo tanto un objetivo de la presente invención proporcionar un operador que optimice la transmisión realizada en el movimiento de apertura y cierre de puertas tipo bus, que ocupe un espacio mínimo y que no comporte componentes que requieran un costoso mantenimiento. Explicación de la invención In addition, the operators known to date include complex transmission systems by means of reduction pulleys, chains or belts, which although located within the chassis, increase the total cost of the operator and therefore hinder and increase the maintenance operations of the elevator. It is therefore an objective of the present invention to provide an operator that optimizes the transmission performed in the opening and closing movement of bus doors, which occupies a minimum space and that does not include components that require costly maintenance. Explanation of the invention.
Con objeto de aportar una solución a los inconvenientes planteados, se da a conocer un operador del movimiento entre una posición cerrada y una posición abierta de una puerta plegable de cabina de ascensor de dos o más hojas articuladas que se abaten en su apertura comprimiéndose a modo de acordeón, es decir, de una puerta tipo BUS. In order to provide a solution to the problems raised, an operator of the movement is disclosed between a closed position and an open position of a folding elevator car door with two or more articulated blades that are folded in their opening, compressed by way of accordion, that is, a BUS type door.
En esencia, el operador se caracteriza porque comprende un chasis fijo, dos ejes principales giratorios con respecto del chasis, destinados a aplicar un movimiento de giro a sendas hojas de una puerta plegable para su arrastre y abatimiento, un grupo motor dispuesto entre los dos ejes principales provisto de un eje de salida perpendicular a los dos ejes principales, y un mecanismo de transmisión que comprende dos juegos de biela-manivela accionados por el eje de salida del grupo motor, destinado a transmitir el movimiento de rotación del eje de salida del grupo motor y convertirlo en un movimiento de giro simultáneo y coordinado de los dos ejes principales. Por eje de salida del grupo motor se entiende el eje de salida que acciona directamente el giro de la manivela de cada juego de biela-manivela. Así por ejemplo, si el eje del motor está acoplado a un grupo reductor y este grupo comprende un eje que está acoplado a la manivela de cada juego de biela-manivela, el eje de salida del grupo motor será
este eje, no el eje del motor. En cambio, si es el eje del motor el que directamente está acoplado a la manivela, el eje de salida del grupo motor será el eje de salida del motor. Como se explicará más adelante, los componentes del operador y el hecho de que el eje de salida del grupo motor esté dispuesto perpendicular a los dos ejes principales, que son los que están alineados con los ejes de giro de las puertas plegables, permiten que todo el operador pueda colocarse dentro de un chasis en forma de caja dispuesto en el dintel de la cabina de un ascensor, sin que el grupo motor ni ningún otro componente del operador sobresalga por encima ni por delante, resultando un operador muy compacto. Para ello, el chasis en forma de caja no difiere de los ya existentes, es decir, no se trata de que las dimensiones del chasis se han incrementado para alojar el operador en su interior, sino que gracias al operador no se requiere de ningún espacio adicional, aprovechando el que ya ocupan las cajas que alojan a los operadores convencionales y se ahorra el espacio por encima de la caja. En particular, el ancho de la caja, medido en la dirección perpendicular al plano de las puertas en posición cerrada es igual o menor que el ancho de la pisadera de la puerta de cabina del ascensor, y la altura de la caja no supera los 190 mm, incluso llegando a no ser superior a 180 mm. In essence, the operator is characterized in that it comprises a fixed chassis, two main rotating axes with respect to the chassis, intended to apply a turning movement to two sheets of a folding door for its drag and drop, a motor group arranged between the two axes main provided with an output shaft perpendicular to the two main axes, and a transmission mechanism comprising two sets of connecting rod-crank operated by the output shaft of the motor group, intended to transmit the rotational movement of the output shaft of the group engine and turn it into a simultaneous and coordinated turning movement of the two main axes. The output shaft of the motor group means the output shaft that directly drives the rotation of the crank of each crank-crank set. For example, if the motor shaft is coupled to a reduction group and this group comprises an axis that is coupled to the crank of each crank-crank set, the output shaft of the motor group will be this axis, not the motor shaft. On the other hand, if it is the motor shaft that is directly coupled to the crank, the output shaft of the engine group will be the output shaft of the engine. As will be explained below, the operator components and the fact that the output axis of the motor group is arranged perpendicular to the two main axes, which are those that are aligned with the pivot axes of the folding doors, allow everything The operator can be placed inside a box-shaped chassis arranged on the lintel of an elevator car, without the engine group or any other operator component protruding above or in front, resulting in a very compact operator. For this, the box-shaped chassis does not differ from those already existing, that is, it is not that the dimensions of the chassis have been increased to accommodate the operator inside, but that thanks to the operator no space is required In addition, taking advantage of the one already occupied by the boxes that house conventional operators and saving space above the box. In particular, the width of the box, measured in the direction perpendicular to the plane of the doors in the closed position is equal to or less than the width of the foot of the elevator car door, and the height of the box does not exceed 190 mm, even not exceeding 180 mm.
Según otra característica de la invención, los juegos de biela-manivela del mecanismo de transmisión son con articulaciones de más de un grado de libertad. According to another feature of the invention, the crank-crank sets of the transmission mechanism are with joints of more than one degree of freedom.
Conforme a otra característica de la invención, los juegos de biela- manivela del mecanismo de transmisión son con articulaciones de rótula o cardán. Las articulaciones de rótula, también denominadas esféricas, y las de cardán, aseguran la capacidad de giro, entre otros, en un plano perpendicular al eje de salida del grupo motor y en un plano perpendicular a los ejes principales. According to another feature of the invention, the crank sets of the transmission mechanism are with ball or joint joints. The ball joints, also called spherical, and those of cardan, ensure the ability to turn, among others, in a plane perpendicular to the output axis of the motor group and in a plane perpendicular to the main axes.
De acuerdo con otra característica de la invención, el mecanismo de transmisión se completa con sendos transmisores de momento que conectan el pie de cada biela con los ejes principales asociados.
En una variante de interés, los transmisores de momento comprenden una palanca acodada transmisora con capacidad de giro alrededor de un eje fijo al chasis y paralelo a los ejes principales; y un tirante que vincula un primer brazo de la citada palanca acodada transmisora con el pie de una biela asociada. According to another feature of the invention, the transmission mechanism is completed with two moment transmitters that connect the foot of each connecting rod with the associated main axes. In a variant of interest, the moment transmitters comprise a bent transmitter lever with the ability to rotate about a fixed axis to the chassis and parallel to the main axes; and a tie that links a first arm of said cranked transmitter lever with the foot of an associated connecting rod.
Así, cada transmisor de momento es capaz de transmitir un momento a un correspondiente eje principal, y está formado por piezas articuladas entre sí que se mueven en planos perpendiculares al eje principal, en el que el movimiento de giro de la manivela en un plano perpendicular el eje de salida del grupo motor se transmite a cada transmisor de momento mediante la biela del juego de biela-manivela. Thus, each moment transmitter is capable of transmitting a moment to a corresponding main axis, and is formed by articulated pieces that move in planes perpendicular to the main axis, in which the crank rotation movement in a perpendicular plane The output shaft of the motor group is transmitted to each moment transmitter by means of the connecting rod-crank set.
Según esta variante de interés, el tirante está unido articulado a la citada palanca acodada transmisora según un eje de giro también paralelo a los ejes de giro principales, con lo que la palanca acodada transmisora y el tirante forman un mecanismo articulado en un mismo plano de movimiento perpendicular a los ejes principales. Conforme a otra característica de la variante de interés, el segundo brazo de la palanca acodada transmisora está unido articulado a un eje excéntrico del eje principal asociado. According to this variant of interest, the linkage is connected articulated to said cranked transmission lever according to an axis of rotation also parallel to the main rotation axes, whereby the transmitter bent lever and the linkage form an articulated mechanism in the same plane of perpendicular movement to the main axes. According to another characteristic of the variant of interest, the second arm of the transmitting bent lever is connected articulated to an eccentric axis of the associated main axis.

Según otra característica de la variante de interés, el eje principal asociado a un juego de biela-manivela del mecanismo de transmisión y el eje en torno al cual gira la palanca acodada transmisora del correspondiente transmisor de momento, están dispuestos en lados opuestos con respecto a la dirección en la que se extiende la biela del juego de biela-manivela. Esto quiere decir que, considerando un chasis en forma de caja, el eje en torno al cual gira la palanca acodada transmisora está dispuesto próximo a un segundo lado del chasis que es opuesto a un primer lado del chasis en el que están situados, o al que están más próximos, el eje de salida del grupo motor y los ejes principales. According to another characteristic of the variant of interest, the second arm of the transmitting bent lever is connected articulated to the eccentric axis by means of a transmitting rod connected, by a first end, to the second arm of the transmitting bent lever, and by a second end. , to the eccentric axis, parallel to the associated main axis, around which the transmitting rod is rotatable in a plane perpendicular to the associated main axis, the eccentric axis rotating around the associated main axis along a circumferential arc path, being separated of the main axis associated by a separator part articulated to the eccentric axis and fixedly connected to the associated main axis. According to another characteristic of the variant of interest, the main axis associated with a crank-crank set of the transmission mechanism and the axis around which the transmitting bent lever of the corresponding moment transmitter rotates, are arranged on opposite sides with respect to the direction in which the connecting rod of the crank-crank set extends. This means that, considering a box-shaped chassis, the axis around which the transmitting bent lever rotates is arranged next to a second side of the chassis that is opposite to a first side of the chassis on which they are located, or to the which are closer, the output shaft of the motor group and the main axes.
Conforme a otra característica de la variante de interés, en una posición abierta de la puerta, el eje excéntrico de cada transmisor de momento está alojado en el espacio entre el primer brazo y el segundo brazo de la palanca acodada transmisora del transmisor de momento, mientras que en una posición cerrada, el eje excéntrico está dispuesto fuera del espacio entre el primer brazo y el segundo brazo de la palanca acodada transmisora. According to another characteristic of the variant of interest, in an open position of the door, the eccentric axis of each moment transmitter is housed in the space between the first arm and the second arm of the transmitter bent lever of the moment transmitter, while that in a closed position, the eccentric shaft is disposed outside the space between the first arm and the second arm of the transmitting bent lever.
De acuerdo con otra característica de la variante de interés, en una posición cerrada de la puerta, el primer extremo de la biela transmisora de cada transmisor de momento está en el mismo lado que el eje principal asociado, con respecto a la dirección en la que se extiende la biela del juego de biela-manivela asociado al transmisor de momento, mientras que en la posición abierta de la puerta, el primer extremo de la biela transmisora está en el lado opuesto, el lado, con respecto a la dirección en la que se extiende la biela, en el que está dispuesto el eje en torno al cual gira la palanca acodada transmisora del mismo transmisor de momento. According to another characteristic of the variant of interest, in a closed position of the door, the first end of the connecting rod of each moment transmitter is on the same side as the associated main axis, with respect to the direction in which the connecting rod of the connecting rod-crankset associated with the moment transmitter is extended, while in the open position of the door, the first end of the connecting rod is on the opposite side, the side, with respect to the direction in which the connecting rod is extended, on which the shaft around which the cranked transmitter lever of the same moment transmitter is rotated.

De este modo una misma manivela puede transmitir el movimiento de giro del eje de salida del grupo motor a las dos bielas situadas una a cada uno de sus lados.
Es preferible que el operador objeto de la invención sea auto portable para que sea fácilmente instalable en el dintel de una cabina de ascensor. Es por este motivo que la invención también se refiere a un sistema de apertura y cierre de puertas de dos o más hojas del tipo bus, eso es puertas plegables, divididas en dos o más hojas que al abrirse se articulan entre sí comprimiéndose la puerta a modo de acordeón. It should be noted that preferably, the two crank-cranksets share the same crank, so that each crank of the two crank-cranksets is attached, through a corresponding articulation of more than one degree of freedom, preferably by a ball joint, at one of the two diametrically opposite ends of the crank. In this way the same crank can transmit the rotational movement of the output shaft of the motor group to the two connecting rods located one on each of its sides. It is preferable that the operator object of the invention is self portable so that it is easily installable on the lintel of an elevator car. It is for this reason that the invention also refers to a system for opening and closing doors of two or more bus-type doors, that is folding doors, divided into two or more leaves that when opened are articulated together by compressing the door to accordion mode

Por ello, el sistema resulta ser ventajosamente muy compacto, ya que ninguno de los componentes del operador sobresale de lo que es el ancho de la pisadera. According to another characteristic of the system object of the invention, as explained above, the chassis is a box-shaped body within which the operator of the invention is housed, the width of the chassis being measured in the direction perpendicular to the plane. of the leaves in closed position, equal to or less than the width of the elevator car door footstep.

En una variante de interés, el operador del sistema es aquel en el que los
dos juegos de biela-manivela comparten una misma manivela orientada esencialmente perpendicular y acoplada solidariamente al eje de salida del grupo motor. Además, también está previsto que la porción plana del chasis comprenda un tope sobresaliente en el mismo sentido en el que sobresale el eje de salida del grupo motor, para limitar el ángulo de giro de la manivela en el movimiento de apertura y cierre de la puerta. Ventajosamente, el chasis en forma de caja dispone, entre la base y la porción plana, de un espacio apto para el montaje de un dispositivo de enclavamiento de la puerta. Breve descripción de los dibujos In a variant of interest, the system operator is the one in which the two sets of crank-crank share the same crank oriented essentially perpendicular and coupled in solidarity with the output shaft of the motor group. In addition, it is also provided that the flat portion of the chassis comprises an outstanding stop in the same direction in which the output shaft of the motor group protrudes, to limit the angle of rotation of the crank in the opening and closing movement of the door .

Descripción detallada de la invención
En las Figs. 1 , 4 y 5 se muestra un operador 1 del movimiento de una puerta plegable de cabina de ascensor en una posición de puerta cerrada, en una posición de puerta abierta y en una posición intermedia entre cerrada y abierta, respectivamente. La puerta plegable, no representada en los dibujos, es de tipo bus, formada por dos o más hojas articuladas que se abaten en su apertura comprimiéndose a modo de acordeón. Detailed description of the invention In Figs. 1, 4 and 5 shows an operator 1 of the movement of a folding elevator car door in a closed door position, in an open door position and in an intermediate position between closed and open, respectively. The folding door, not represented in the drawings, is of the bus type, formed by two or more articulated sheets that fold in their opening, compressed as an accordion.
Como se aprecia, el operador 1 forma parte de un sistema 100 instalable en el dintel de la cabina de un ascensor, ya que el operador 1 está alojado en el interior de un cuerpo en forma de caja, que constituye un chasis 2 fijo a la cabina de ascensor. La caja, gracias a la particular disposición de los elementos que componen el operador 1 , no requiere ningún incremento en sus dimensiones para alojar al operador, sino que el operador 1 puede ser instalado en las cajas ya existentes en otros ascensores. El ancho del chasis 2, en forma de caja, medido en la dirección perpendicular al plano de las hojas de la puerta en posición cerrada, es igual o menor que el ancho de la pisadera de la puerta de cabina del ascensor, por lo que ninguno de los componentes del operador 1 sobresale de la caja. Por lo que a la altura de la caja se refiere, ésta no supera los 190 mm, e incluso puede tener una altura no superior a 180 mm. Por ello, el sistema 100 resulta especialmente ventajoso por su compacidad, estando alojado todo el operador 1 dentro del chasis 2 en forma de caja sin sobresalir ninguna parte del mismo. As can be seen, the operator 1 is part of a system 100 that can be installed on the lintel of an elevator car, since the operator 1 is housed inside a box-shaped body, which constitutes a chassis 2 fixed to the elevator car The box, thanks to the particular arrangement of the elements that make up the operator 1, does not require any increase in its dimensions to accommodate the operator, but the operator 1 can be installed in the boxes already existing in other elevators. The width of the chassis 2, in the form of a box, measured in the direction perpendicular to the plane of the leaves of the door in the closed position, is equal to or less than the width of the footstep of the elevator car door, so none of the operator 1 components protrudes from the box. As for the height of the box, it does not exceed 190 mm, and may even have a height not exceeding 180 mm. Therefore, the system 100 is especially advantageous because of its compactness, the entire operator 1 being housed inside the chassis 2 in the form of a box without projecting any part thereof.
El chasis 2 comprende una base 21 con una cara exterior orientada hacia las hojas de la puerta, comprendiendo la cara exterior una guía 20 de la puerta de cabina. Por entre la guía 20 deslizan unos pines, bulones o protuberancias asociadas a las hojas de la puerta, por ejemplo, a las hojas centrales de una puerta doble, tipo bus. El operador 1 está instalado de forma que los ejes principales 3 queden verticales, paralelos al eje de giro en torno al cual las hojas conducidas pueden abatirse arrastrando consigo a las mencionadas hojas centrales (no mostradas en los dibujos). The chassis 2 comprises a base 21 with an outer face oriented towards the door leaves, the outer face comprising a guide 20 of the cabin door. Through the guide 20 slide pins, bolts or bulges associated with the door leaves, for example, the central leaves of a double door, bus type. The operator 1 is installed so that the main axes 3 are vertical, parallel to the axis of rotation around which the driven sheets can be folded down by dragging said central sheets (not shown in the drawings).
Además de la base 21 , también comprende una cara rectangular superior 22, paralela a la base 21 y dos marcos laterales dispuestos en un plano vertical,
perpendicular al plano que definen las hojas de la puerta en posición cerrada, que establece la distancia de separación entre la base 21 y la cara rectangular superior 22, es decir, la altura de la caja y por tanto, el espacio disponible para la instalación del operador 1. In addition to the base 21, it also comprises an upper rectangular face 22, parallel to the base 21 and two side frames arranged in a vertical plane, perpendicular to the plane defined by the door leaves in the closed position, which establishes the separation distance between the base 21 and the upper rectangular face 22, that is, the height of the box and therefore the space available for the installation of the operator 1.
La cara rectangular superior 22 está provista de dos orificios pasantes, cada uno situado en una de las dos esquinas más alejadas de la cabina, dentro de los cuales están introducidos y acoplados con capacidad de giro los extremos superiores de unos ejes principales 3 dispuestos por encima de las hojas de la puerta y en coincidencia con los ejes respecto de los cuales giran las hojas. Estos ejes principales 3 forman parte del operador 1 como se explicará posteriormente. The upper rectangular face 22 is provided with two through holes, each located in one of the two corners furthest from the cabin, into which the upper ends of main axes 3 arranged above are inserted and rotatably coupled. of the door leaves and in coincidence with the axes on which the leaves rotate. These main axes 3 are part of the operator 1 as will be explained later.
Además de lo anterior, el chasis 2 comprende una porción plana 23 vertical, paralela al plano de las hojas de la puerta en posición cerrada, situada más próxima al lado de la cara superior 22 que forma las esquinas en las que están dispuestos los ejes principales 3, que al lado opuesto. Esta porción plana 23 constituye un soporte del eje de salida 4 de un grupo motor que forma parte del operador 1 y cuyo sentido de giro horario o antihorario determina si la puerta se abre o se cierra. In addition to the above, the chassis 2 comprises a vertical flat portion 23, parallel to the plane of the door leaves in a closed position, located closer to the side of the upper face 22 that forms the corners on which the main axes are arranged 3, than on the opposite side. This flat portion 23 constitutes a support for the output shaft 4 of a motor group that is part of the operator 1 and whose clockwise or counterclockwise direction determines whether the door is opened or closed.
El operador 1 comprende un chasis 2 fijo, dos ejes principales 3 giratorios con respecto del chasis 2, destinados a aplicar un movimiento de giro a sendas hojas de una puerta plegable para su arrastre y abatimiento, un grupo motor dispuesto entre los dos ejes principales 3 provisto de un eje de salida 4 perpendicular a los dos ejes principales 3, y un mecanismo de transmisión que comprende dos juegos de biela-manivela 6-5 accionados por el eje de salida 4 del grupo motor, destinado a transmitir el movimiento de rotación del eje de salida 4 del grupo motor y convertirlo en un movimiento de giro simultáneo y coordinado de los dos ejes principales 3. Como se pone de manifiesto, el operador 1 está destinado a colocarse sobre el dintel de una puerta de cabina de ascensor, orientado de forma que los dos ejes principales 3 queden verticales y el operador, fijo al chasis 2, viaja junto con la cabina durante el funcionamiento del ascensor.
Los dos juegos de biela-manivela 6-5 comparten, ventajosamente, una misma manivela 5 dispuesta centralmente acoplada esencialmente perpendicular y de forma solidaria al eje de salida 4 del grupo motor alrededor del cual es giratoria. Los juegos de biela-manivela 6-5 del mecanismo de transmisión son con articulaciones de más de un grado de libertad, preferiblemente con articulaciones de rótula 60 o articulaciones cardán. Así, como se aprecia en el detalle ampliado de las Figs. 2, 5 y 8, la manivela 5 está unida, por cada uno de sus dos extremos diametralmente opuestos, a una respectiva biela 6 mediante una articulación de más de un grado de libertad, que convierte el movimiento de giro de la manivela 5 en el plano vertical en un movimiento por el que la biela 6 gira y se desplaza acercándose o alejándose del respectivo eje principal 3 según sea el sentido del giro del eje de salida 4 del grupo motor. The operator 1 comprises a fixed chassis 2, two main axes 3 rotating with respect to the chassis 2, intended to apply a turning movement to two sheets of a folding door for its drag and drop, a motor group arranged between the two main axes 3 provided with an output shaft 4 perpendicular to the two main axes 3, and a transmission mechanism comprising two sets of connecting rod-crank 6-5 driven by the output shaft 4 of the motor group, intended to transmit the rotational movement of the output shaft 4 of the motor group and convert it into a simultaneous and coordinated turning movement of the two main axes 3. As it becomes clear, the operator 1 is intended to be placed on the lintel of an elevator car door, oriented of so that the two main axes 3 are vertical and the operator, fixed to the chassis 2, travels together with the cab during the operation of the elevator. The two sets of crank-crank 6-5 share, advantageously, the same crank 5 centrally arranged essentially perpendicularly coupled to the output shaft 4 of the motor group around which it is rotatable. The crank-crank sets 6-5 of the transmission mechanism are with joints of more than one degree of freedom, preferably with 60 ball joints or cardan joints. Thus, as seen in the enlarged detail of Figs. 2, 5 and 8, the crank 5 is connected, by each of its two diametrically opposite ends, to a respective connecting rod 6 by means of an articulation of more than one degree of freedom, which converts the turning movement of the crank 5 into the vertical plane in a movement through which the connecting rod 6 rotates and moves closer or further away from the respective main axis 3 according to the direction of rotation of the output shaft 4 of the motor group.
También se ve que la porción plana 23 comprende un tope 24 sobresaliente en el mismo sentido en el que sobresale el eje de salida 4 del grupo motor, para limitar el ángulo de giro de la manivela 5 en el movimiento de apertura y cierre de la puerta. It is also seen that the flat portion 23 comprises an abutment stop 24 in the same direction in which the output shaft 4 of the motor group protrudes, to limit the angle of rotation of the crank 5 in the opening and closing movement of the door .
El mecanismo de transmisión se completa con sendos transmisores de momento que conectan el pie de cada biela 6 con los ejes principales 3 asociados. Así, cada biela 6 es la encargada de transmitir el giro de la manivela 5 a un respectivo transmisor de momento formado por piezas articuladas entre sí que se mueven únicamente en planos perpendiculares a un eje principal 3 y al cual transmiten un momento. Para ello, cada biela 6 está acoplada en sus extremos a sendas articulaciones con más de un grado de libertad. The transmission mechanism is completed with two moment transmitters that connect the foot of each connecting rod 6 with the associated main axes 3. Thus, each connecting rod 6 is responsible for transmitting the rotation of the crank 5 to a respective moment transmitter formed by articulated parts that move only in planes perpendicular to a main axis 3 and to which they transmit a moment. For this, each connecting rod 6 is coupled at its ends to two joints with more than one degree of freedom.
Como se verá más adelante, los transmisores de momento comprenden una palanca acodada transmisora 7 con capacidad de giro alrededor de un eje 70 fijo al chasis 2 y paralelo a los ejes principales 3; y un tirante 61 que vincula un primer brazo 71 de la citada palanca acodada transmisora 7 con el pie de una biela 6 asociada. As will be seen below, the moment transmitters comprise a bent transmitter lever 7 with the ability to rotate about an axis 70 fixed to the chassis 2 and parallel to the main axes 3; and a tie 61 that links a first arm 71 of said transmitter bent lever 7 with the foot of an associated connecting rod 6.
En las Figs. 10, 11 y 12, que reflejan la secuencia de apertura de la puerta, se observa que el movimiento de cada biela 6, simultáneamente al
movimiento de traslación por el que se aproxima a los extremos del chasis 2 donde están los ejes principales 3, incluye un movimiento de giro compuesto por el que el movimiento de giro de la biela 6 no está comprendido en un único plano, sino que a la vez que se inclina hacia arriba o hacia abajo, según es la posición del extremo de la manivela 5, también se inclina hacia delante y hacia atrás, es decir, acercándose o alejándose de los lados de la caja que forma el chasis 2 que son paralelos al plano de la puerta en posición cerrada. Por ello, cada biela 6 está unida por sus dos extremos a articulaciones de más de un grado de libertad, en la que por ejemplo, la articulación de unión con un extremo de la manivela 5 es una articulación de rótula 60 que le confiere capacidad de giro, entre otros, en un plano perpendicular al eje de salida 4 del grupo motor y en un plano perpendicular al eje principal 3. Las articulaciones de rótula 60 conforman la articulación de las bielas 6 con los extremos de la manivela 5 (ver Figs. 2, 5 y 8). En su movimiento, las bielas 6 se moverán, cuando la puerta se abra, hacia la pared del fondo del chasis 2 en forma de caja, es decir, hacia el lado opuesto al lado en el que están próximos los ejes principales 3, pero en ningún momento sobresaldrán del ancho de la caja. In Figs. 10, 11 and 12, which reflect the opening sequence of the door, it is observed that the movement of each connecting rod 6, simultaneously with translation movement by which it approaches the ends of the chassis 2 where the main axes 3 are, includes a turning movement composed by which the turning movement of the connecting rod 6 is not comprised in a single plane, but rather to the Once it tilts up or down, depending on the position of the end of the crank 5, it also leans forward and backward, that is, approaching or moving away from the sides of the box that forms the chassis 2 that are parallel to the plane of the door in closed position. Therefore, each connecting rod 6 is connected at both ends to joints of more than one degree of freedom, in which, for example, the joint with one end of the crank 5 is a ball joint 60 which gives it the ability to rotation, among others, in a plane perpendicular to the output axis 4 of the motor group and in a plane perpendicular to the main axis 3. The ball joints 60 make up the articulation of the connecting rods 6 with the ends of the crank 5 (see Figs. 2, 5 and 8). In its movement, the connecting rods 6 will move, when the door is opened, towards the bottom wall of the box-shaped chassis 2, that is, towards the opposite side to the side on which the main axes 3 are close, but in no moment will protrude from the width of the box.
Por su extremo opuesto al de la manivela 5, cada biela 6 está unida mediante una articulación de más de un grado de libertad a uno de los dos extremos de un transmisor de momento, dispuesto entre la biela 6 y el eje principal 3, concretamente a un extremo del tirante 61 que vincula el primer brazo 71 de la palanca acodada transmisora 7 con el pie de la biela 6. Cada transmisor de momento está adaptado para transmitir el momento generado por el giro de la manivela 5 y la traslación y giro de la biela 6 a un respectivo eje principal 3. At its opposite end to that of the crank 5, each connecting rod 6 is connected by an articulation of more than one degree of freedom to one of the two ends of a moment transmitter, arranged between the connecting rod 6 and the main shaft 3, specifically a one end of the strap 61 that links the first arm 71 of the transmitter bent lever 7 with the foot of the connecting rod 6. Each moment transmitter is adapted to transmit the moment generated by the rotation of the crank 5 and the translation and rotation of the connecting rod 6 to a respective main shaft 3.
Los transmisores de momento que transmiten el momento al eje principal 3 de la izquierda, están representados en detalle en las Figs. 3, 5 y 9, en una posición de puerta cerrada, de puerta abierta y en una posición intermedia entre cerrada y abierta. La secuencia de movimiento desde una posición cerrada hasta una posición abierta es la representada en las Figs. 13 a 15. The moment transmitters that transmit the moment to the main axis 3 on the left, are shown in detail in Figs. 3, 5 and 9, in a closed door, open door position and in an intermediate position between closed and open. The sequence of movement from a closed position to an open position is shown in Figs. 13 to 15
Como se ha mencionado anteriormente, cada palanca acodada
transmisora 7 tiene capacidad de giro alrededor de un eje 70 fijo al chasis 2 y paralelo a los ejes principales 3. Para ello, el eje 70 se encuentra anclado fijamente por su extremo inferior a una placa horizontal que forma parte del chasis 2, atravesando el vértice de la palanca acodada transmisora 7 que separa el primer brazo 71 del segundo brazo 72. También se aprecia que el eje 70 está más próximo a un segundo lado del chasis 2 que es opuesto a un primer lado del chasis 2 en el que están situados, o al que están más próximos, el eje de salida 4 del grupo motor y los ejes principales 3. Si se traza una línea según la dirección en la que se extiende la correspondiente biela 6 (ver línea a trazos en las Figs. 13-15), se aprecia que el eje principal 3 asociado a un juego de biela- manivela 6-5 y el eje 70 en torno al cual gira la palanca acodada transmisora 7 del correspondiente transmisor de momento, están dispuestos en lados opuestos. En cada transmisor de momento, el tirante 61 está unido articulado a su palanca acodada transmisora 7 según un eje de giro también paralelo a los ejes de giro principales 3, con lo que la palanca acodada transmisora 7 y el tirante 61 forman un mecanismo articulado en un mismo plano de movimiento perpendicular a los ejes principales 3. As mentioned above, each lever bent Transmitter 7 has the ability to rotate around an axis 70 fixed to the chassis 2 and parallel to the main axes 3. To this end, the axis 70 is fixedly anchored by its lower end to a horizontal plate that is part of the chassis 2, crossing the vertex of the transmitter bent lever 7 that separates the first arm 71 from the second arm 72. It is also appreciated that the axis 70 is closer to a second side of the chassis 2 which is opposite to a first side of the chassis 2 in which they are located , or to which they are closest, the output shaft 4 of the motor group and the main axes 3. If a line is drawn according to the direction in which the corresponding connecting rod 6 extends (see broken line in Figs. 13- 15), it can be seen that the main axis 3 associated with a crankset 6-5 and the axis 70 around which the transmitter bent lever 7 of the corresponding moment transmitter rotates, are arranged on opposite sides. In each moment transmitter, the rod 61 is connected articulated to its transmitter bent lever 7 along a rotation axis also parallel to the main rotation axes 3, whereby the transmitter bent lever 7 and the strap 61 form an articulated mechanism in the same plane of movement perpendicular to the main axes 3.
El segundo brazo 72 de la palanca acodada transmisora 7 está unido articulado a un eje excéntrico 9 del eje principal 3 asociado. Particularmente, el segundo brazo 72 de la palanca acodada transmisora 7 está unido articulado al eje excéntrico 9 mediante una biela transmisora 8. La biela transmisora 8 está unida, por su primer extremo 81 , al segundo brazo 72 de la palanca acodada transmisora 7, y por un segundo extremo 82, al eje excéntrico), paralelo al eje principal 3 asociado, en torno al cual la biela transmisora 8 es giratoria en un plano perpendicular al eje principal 3 asociado. El eje excéntrico 9 es giratorio en torno al eje principal 3 asociado, el más próximo, y su giro describe una trayectoria de arco de circunferencia, es decir, de radio constante, al estar separado del eje principal 3 por una pieza separadora 30, unida articuladamente al eje auxiliar transmisor 9 y unida fijamente al eje principal 3 asociado. En las Figs. 3, 6 y 9 se percibe que el eje auxiliar transmisor
9 es paralelo al eje principal 3 (es decir, en una posición de montaje sobre la cabina de un ascensor, estos ejes son verticales). The second arm 72 of the transmitter bent lever 7 is connected articulated to an eccentric shaft 9 of the associated main shaft 3. Particularly, the second arm 72 of the transmitting bent lever 7 is connected articulated to the eccentric shaft 9 by means of a connecting rod 8. The connecting rod 8 is connected, at its first end 81, to the second arm 72 of the transmitting bent lever 7, and by a second end 82, to the eccentric axis), parallel to the associated main axis 3, around which the connecting rod 8 is rotatable in a plane perpendicular to the associated main axis 3. The eccentric axis 9 is rotatable about the associated main axis 3, the closest, and its rotation describes a circumferential arc path, that is, of constant radius, being separated from the main axis 3 by a separating part 30, joined articulated to the auxiliary transmitter axis 9 and fixedly connected to the associated main axis 3. In Figs. 3, 6 and 9 it is perceived that the auxiliary transmitter shaft 9 is parallel to the main axis 3 (that is, in a mounting position on the elevator car, these axes are vertical).
En una posición abierta de la puerta, como la representada en la Fig. 15, el eje excéntrico 9 de cada transmisor de momento está alojado en el espacio entre el primer brazo 71 y el segundo brazo 72 de la palanca acodada transmisora 7 del transmisor de momento, mientras que en una posición cerrada, el eje excéntrico 9 está dispuesto fuera del espacio entre el primer brazo 71 y el segundo brazo 72. In an open door position, such as that shown in Fig. 15, the eccentric shaft 9 of each moment transmitter is housed in the space between the first arm 71 and the second arm 72 of the transmitter bent lever 7 of the transmitter moment, while in a closed position, the eccentric shaft 9 is disposed outside the space between the first arm 71 and the second arm 72.
En la posición cerrada de la puerta, también se observa que el primer extremo 81 de la biela transmisora 8 de cada transmisor de momento está más próximo al lado del chasis 2 en el que está situado, o al que está más próximo, el correspondiente eje principal 3, mientras que en la posición abierta de la puerta, el primer extremo 81 de la biela transmisora 8 está en el lado o situado más próximo al lado del chasis 2 en el que está dispuesto fijamente el eje 70 fijo al chasis 2 respecto del cual gira la palanca acodada transmisora 7. Trazando una línea según la dirección de la correspondiente biela 6, se observa que dicho primer extremo 81 está, en la posición cerrada de la puerta, en el mismo lado que el eje principal 3, pero que al abrirse la puerta, el primer extremo 81 se mueve pasando al otro lado de la línea, acabando en el lado en el que se encuentra el eje 70. In the closed position of the door, it is also observed that the first end 81 of the connecting rod 8 of each moment transmitter is closer to the side of the chassis 2 in which the corresponding axis is located, or to which it is closer main 3, while in the open position of the door, the first end 81 of the connecting rod 8 is on the side or located closest to the side of the chassis 2 in which the shaft 70 fixedly fixed to the chassis 2 is fixedly arranged in relation to the which rotates the angled transmitter lever 7. Drawing a line according to the direction of the corresponding connecting rod 6, it is observed that said first end 81 is, in the closed position of the door, on the same side as the main axis 3, but that at the opening the door, the first end 81 moves past the other side of the line, ending on the side where the axis 70 is.
En las Figs. 1 , 4 y 7 se aprecia que debajo de la manivela 5 existe un espacio considerable hasta la base 21 del chasis 2 en forma de caja, apto para instalar un dispositivo de enclavamiento, como se demuestra en las Figs. 10 a 12. Así pues, se pone de manifiesto que el operador constituye una solución ventajosamente compacta ya que está contenido en el chasis 2 en forma de caja sin incrementar en modo alguno el tamaño de la caja en comparación con las cajas de otros operadores convencionales que o bien sobresalen de la misma en un plano perpendicular al de la puerta en posición cerrada o incluyen elementos del operador dispuestos por encima de sus cajas.
In Figs. 1, 4 and 7 it can be seen that there is considerable space under the crank 5 to the base 21 of the box-shaped chassis 2, suitable for installing an interlocking device, as shown in Figs. 10 to 12. Thus, it is clear that the operator constitutes an advantageously compact solution since it is contained in the chassis 2 in the form of a box without increasing in any way the size of the box compared to the boxes of other conventional operators which either protrude from it in a plane perpendicular to that of the door in the closed position or include operator elements arranged above their boxes.
