Abstract

The classical pneumatic cylinder actuating the longitudinal guide (3) ensuring sliding of the doors and by means of which the doors (1) are embedded or disembedded in the body (2) of the wagon, simultaneously actuates a shaft (4), a crank (5) being radially integral with said shaft . The free end of the crank hingedly receives a connecting rod (6) that is in turn hingedly connected to the longitudinal guide (3). When the longitudinal guide (3) is being displaced outward, on which the doors (1) can be displaced in closing or opening direction, the crank (5) and the connecting rod (6) form an approximate angle α. Said angle progressively decreases during the embedding maneuver of the guide (3) and, consequently, the doors (1), until a limit situation is reached in which a 0 value of said angle is slightly exceeded and the connecting rod (6) operates as blocking and safety element that keeps the doors in the embedded position thereby preventing improper opening of said doors.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo que ha sido especialmente concebido para bloquear o asegurar el cierre de puertas eneajabíes-deslizantes como las utilizadas en vagones de metro, en trenes y similares, donde la apertura se inicia con un desplazamiento frontal de la puerta, para su desencaje del cuerpo de vagón o elemento de que se trate, y se complementa con el movimiento lateral de corredera propiamente dicho.The present invention relates to a device that has been specially designed to block or secure the closing of sliding and sliding doors such as those used in subway cars, trains and the like, where the opening starts with a front door movement, for its disengagement from the car body or element in question, and is complemented by the lateral sliding movement itself.
El objeto de la invención es conseguir que tras la maniobra de cierre de las puertas se establezca un bloqueo seguro de las mismas en tal posición, que haga totalmente imposible una apertura accidental o forzada por cualquier agente ajeno al dispositivo de accionamiento de las mismas.The object of the invention is to ensure that, after the closing operation of the doors, a safe locking of the doors is established in such a position, which makes accidental or forced opening by any agent outside the actuation device thereof completely impossible.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En cerramientos como los correspondientes a los ejemplos anteriormente citados, donde habitualmente participan dos puertas encajables y deslizantes que deben moverse sincronizadamente, una de las soluciones comúnmente utilizadas, por razones de simplicidad estructural y funcional, consiste en la utilización de un cilindro neumático que actúa directamente sobre una de las puertas, mientras que la segunda puerta recibe el movimiento de la primera a través de una correa de transmisión, para conseguir un movimiento sincronizado.In enclosures such as those corresponding to the aforementioned examples, where two interlocking and sliding doors usually participate, which must be moved synchronously, one of the commonly used solutions, for reasons of simplicity structural and functional, it consists in the use of a pneumatic cylinder that acts directly on one of the doors, while the second door receives the movement of the first through a transmission belt, to achieve a synchronized movement.
De forma más concreta la puerta directamente accionada por el cilindro neumático está provista de una cremallera que en su desplazamiento longitudinal hace girar a un piñón sobre cuyo eje está montada la correa de transmisión que relaciona dicho piñón con otro acoplado a la cremallera de la segunda puerta, de manera que utilizando piñones y cremalleras idénticos el movimiento de una puerta es transmitido a la otra con una perfecta simetría.More specifically, the door directly actuated by the pneumatic cylinder is provided with a rack that rotates a pinion on its axis on whose axis the transmission belt that connects said pinion with another coupled to the rack of the second door is mounted. , so that using identical pinions and zippers the movement of one door is transmitted to the other with perfect symmetry.
Pero además, en este tipo de vehículos y por sus propias condiciones de funcionamiento, se requiere de una buena penetración aerodinámica, de una minimización del ruido generado en su desplazamiento y, lógicamente, de un buen cierre en las puertas, desde el punto de vista de estanqueidad. Para conseguir estos objetivos las puertas encajables-deslizantes de este tipo cuentan con mecanismos que permiten para las mismas un movimiento combinado, de manera que en situación de máxima aproximación para las puertas, es decir en situación de cierre, dichas puertas, conjuntamente con sus guias para desplazamiento por corredera, puedan encajarse en el cuerpo del vagón estableciendo un cierre más o menos estanco y estableciendo además 'continuidad superficial entre las puertas y el cuerpo del vagón, optimizando la aerodinámica de este último y evitando la generación de los ruidos que producirla el aire al chocar contra el borde de las puertas .But in addition, in this type of vehicle and due to its own operating conditions, a good aerodynamic penetration is required, a minimization of the noise generated in its displacement and, logically, a good closing on the doors, from the point of view of tightness To achieve these objectives, the sliding-sliding doors of this type have mechanisms that allow for them a combined movement, so that in a situation of maximum approximation for the doors, that is to say in a closed situation, said doors, together with their guides for sliding travel, they can fit into the body of the car by establishing a more or less tight seal and also establishing ' surface continuity between the doors and the car body, optimizing the aerodynamics of the latter and avoiding the generation of the noise that the air will produce when it hits the edge of the doors.
Habitualmente y para conseguir este desplazamiento frontal o transversal de las guias a las que están asociadas las puertas, se utilizan cilindros neumáticos de doble efecto que, con la colaboración de guias apropiadas, generan el movimiento preciso. Sin embargo esta solución presenta como problema fundamental el hecho de que son los propios cilindros los que mantienen la puerta acuñada en situación de cierre, de manera que ante una pérdida de presión en los mismos, por cualquier causa, la puerta queda desbloqueada y en condiciones de desplazarse hacia afuera ante cualquier presión o apoyo interior, como por ejemplo el simple apoyo corporal de los pasajeros.Usually and to achieve this frontal or transverse displacement of the guides to which the doors are associated, double acting pneumatic cylinders are used which, with the collaboration of appropriate guides, generate the precise movement. However, this solution presents as a fundamental problem the fact that it is the cylinders themselves that keep the door wedged in a closed situation, so that before a loss of pressure in them, for any reason, the door is unlocked and in conditions to move outward to any pressure or internal support, such as simple passenger body support.
Existen otros tipos de puertas donde el bloqueo de las mismas se efectúa mediante ganchos, lo que significa que todo el esfuerzo recae sobre tales ganchos, lo que hace que deban ser sobredimensionados los mismos o colocados en un mayor número haciendo, si cabe, más complicado el sistema.There are other types of doors where they are blocked by hooks, which means that all the effort falls on such hooks, which means that they must be oversized or placed in a larger number making, if possible, more complicated the system.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El dispositivo de bloqueo para puertas que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, por cuanto que a término de la fase de cierre o encajamiento de las puertas, provoca una situación de bloqueo para las mismas, que no permite sobre dichas puertas otra manipulación que no sea la efectuada con el propio dispositivo de accionamiento de las mismas, durante la maniobra de apertura.The locking device for doors that the invention proposes solves in a completely satisfactory way the problem previously exposed, since at the end of the closing or fitting phase of the doors, it causes a blocking situation for them, which does not allow on said doors any manipulation other than that carried out with the same drive device, during the opening maneuver.
Para ello y de forma más concreta se ha previsto que el clásico mecanismo de accionamiento de las puertas, para encajamiento/desencajamiento de las mismas, a la vez que suministra un desplazamiento frontal a las guias longitudinales y correspondientes de dichas puertas, suministre un .movimiento giratorio a un eje dotado de una manivela, fijada radialmente a dicho eje por uno de sus extremos, de manera que lo acompañe en su movimiento giratorio, con un movimiento de basculación, y que recibe por su otro extremo y de forma articulada a una biela que relaciona dicha manivela con las guias longitudinales de las puertas, pero habiéndose previsto que la disposición relativa entre el sistema de puertas, el eje de basculación de la manivela, la longitud de esta última y la longitud de la biela, sean tales que en situación de cierre o acuñamiento para el sistema de puertas en el cuerpo del vagón, el desencajamiento de dicho sistema sólo sea posible con una basculación lateral de esta biela, que además sólo es factible a su vez mediante un ligero incremento momentáneo en el acuñamiento del sistema de cierre, lo que obviamente es contrario a las normales acciones que los pasajeros van a efectuar sobre la cara interna de las puertas, es decir al apoyo sobre las mismas. De esta manera y a través de esta biela se consigue el bloqueo de las puertas, en situación limite de cierre, en unas condiciones de total seguridad frente a un eventual fallo en el cilindro de acuñamiento de las mismas y frente a cualquier tipo de acción habitual desde el interior del vagón.For this, and more specifically, it is provided that the classic mechanism for driving the doors, to engage / disengage them, while providing a frontal displacement to the longitudinal and corresponding guides of said doors, provides a movement. rotating to a shaft provided with a crank, fixed radially to said shaft by one of its ends, so that it accompanies it in its rotating movement, with a tilting movement, and that receives at its other end and articulated to a connecting rod which relates said crank with the longitudinal guides of the doors, but having provided that the relative arrangement between the door system, the axis of tilt of the crank, the length of the latter and the length of the connecting rod, are such that in situation of closing or wedging for the door system in the body of the car, disengagement of said system is only possible with a lateral tilt of e This connecting rod, which is also only feasible in turn by a slight momentary increase in the coining of the closing system, which is obviously contrary to the normal actions that passengers will perform on the inner side of the doors, that is to say support on them. In this way and through this connecting rod the door lock is achieved, in a limited situation of closing, in conditions of total security against an eventual failure in the cylinder of minting them and against any type of habitual action from inside the car.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
En la figura reseñada se observa como el dispositivo de la invención es aplicable por ejemplo a puertas (1) susceptibles de encajar en el cuerpo del vagón (2), estableciendo continuidad superficial externa con el mismo, o de desencajarse y desplazarse hacia fuera con la colaboración de guias transversales, no representadas, a las cuales son solidarias guias longitudinales (3) sobre las que a su vez se produce el desplazamiento longitudinal de las puertas (1) , que va dar lugar a la apertura propiamente dicha, cuando dichas guias longitudinales (3) han emergido suficientemente al exterior del cuerpo (2) del vagón, accionamiento longitudinal que se lleva a cabo, por ejemplo, mediante un cilindro neumático paralelo a dichas guias (3) y tampoco representado en las figuras, mientras que el encaje/desencaje de las guias (3) se lleva a cabo con la colaboración de otro cilindro neumático, que por ser convencional tampoco ha sido representado, y que a la vez que actúa sobre dichas guias (3) suministra un movimiento giratorio, en uno u otro sentido, a un eje (4) que relaciona el sistema de accionamiento de las puertas con el dispositivo de bloqueo de la invención.The above figure shows how the device of the invention is applicable, for example, to doors (1) capable of fitting into the body of the car (2), establishing external surface continuity with it, or of disengaging and moving outwards with the collaboration of transverse guides, not represented, to which are longitudinal guides (3) on which the longitudinal displacement of the doors (1) takes place, which will lead to the opening itself, when said longitudinal guides (3) have emerged sufficiently outside the door. body (2) of the wagon, longitudinal drive that is carried out, for example, by a pneumatic cylinder parallel to said guides (3) and also not shown in the figures, while the fitting / disengagement of the guides (3) is carried carried out with the collaboration of another pneumatic cylinder, which, because it is conventional, has not been represented, and that at the same time acting on said guides (3) provides a rotating movement, in one direction or another, to an axis (4) that relates the door drive system to the locking device of the invention.
Pues bien, a este eje (4) es solidaria una manivela (5), convenientemente enchavetada al mismo, de manera que dicha manivela (5) bascula cuando gira el eje (4), acompañando a éste en uno o en' otro sentido, transmitiendo su movimiento de basculación a una biela (6) que une articuladamente la manivela (5) con la guia longitudinal (3) de las puertas.However, this axis (4) is secured a crank (5), conveniently keyed to it, so that said crank (5) swivels when the shaft (4) rotates, accompanying it in one or 'otherwise, transmitting its tilting movement to a connecting rod (6) that joins the crank (5) with the longitudinal guide (3) of the doors.
De forma más concreta, como se observa perfectamente en la figura, la manivela (5) y la biela (6) forman un ángulo de aproximadamente 90° cuando el sistema de puertas está desencajado, es decir cuando la guia (3) está proyectada hacia afuera, y a partir de esta situación y a medida que se va produciendo el encaje por retracción del cilindro de accionamiento, el ángulo formado por la biela (6) y la manivela (5) va disminuyendo, sobrepasando el valor cero antes de alcanzar la situación limite de cierre, de manera que en tal situación limite de cierre y como se observa igualmente en la figura, la biela (6) ha sobrepasado el eje (4) y se encuentra en una situación de autobloqueo que imposibilita de todo punto el desencajamiento de las puertas (1) , ante una presión interna sobre las mismas, como por ejemplo la presión corporal de los pasajeros del vagón, ya que para que tal desencajamiento se produzca la biela (6) debe bascular lateralmente hasta sobrepasar el eje (4), en una maniobra inicial en la que, como anteriormente se ha dicho, momentáneamente el nivel de encajamiento debe incrementarse para sobrepasar la posición de tensión máxima o limite en el que el eje de la biela (6) pasa por el centro del eje (4) . More specifically, as can be seen perfectly in the figure, the crank (5) and the connecting rod (6) form an angle of approximately 90 ° when the door system is unlocked, that is, when the guide (3) is projected towards outside, and from this situation and as the lace is produced by retraction of the drive cylinder, the angle formed by the connecting rod (6) and the crank (5) decreases, exceeding the zero value before reaching the closing limit situation, so that in such a closing limit situation and as observed also in the figure, the connecting rod (6) has exceeded the shaft (4) and is in a self-locking situation that makes it impossible to disengage the doors (1), due to an internal pressure on them, such as for example the body pressure of the passengers of the wagon, since for such disengagement the connecting rod (6) must be tilted laterally until it exceeds the axle (4), in an initial maneuver in which, as previously stated, the level is momentarily of engagement must be increased to exceed the position of maximum tension or limit in which the axis of the connecting rod (6) passes through the center of the axis (4).
