Abstract

Said mechanism comprises a carriage (1) that is designed to be fixed to one of the edges of the door and which follows the same trajectory as that of the door, said carriage sliding by means of pulleys on a support profile (7) that includes the ends of a toothed belt (3) which are appropriately fixed to the ends thereof. The belt passes through a set of rollers (4-5-5') that are mounted on a support (6) and fixed to said support profile (7). One of said rollers (4) receives the movement of an electric motor (9) that is also mounted on the support (6) in such a way that rotation in a given direction of the rotor of said motor (9) causes the carriage (1) and, consequently, the door associated with said carriage, to move in a given direction and vice versa. A moving arm (12) that is also mounted on the support (6) causes the door to be blocked in a close limit position of said door when it is interlocked in a location (14) of the carriage (1). The carriage can be released from said interlocking position by a rotation of the stator of the motor (9) or manually with the aid of a cam (15), both elements acting upon the arm (12).

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención se refiere a un mecanismo que ha sido especialmente concebido para la movilización de puertas correderas, que resulta especialmente idóneo para ser utilizado en puertas de vagones de ferrocarril, pero que resulta igualmente útil en cualquier otro supuesto práctico en el que una puerta corredera deba ser accionada a distancia, tanto en sentido de apertura como en sentido de cierre, y que además deba mantener estable la posición de cierre frente a accionamientos manuales y no autorizados sobre la misma, permitiendo sin embargo un accionamiento manual en situación de emergencia, como por ejemplo ante un fallo en la corriente eléctrica de alimentación de su motor, o un fallo en el propio motorThe present invention relates to a mechanism that has been specially designed for the mobilization of sliding doors, which is especially suitable for use in railroad car doors, but which is equally useful in any other practical case in which a sliding door must be remotely operated, both in the direction of opening and in the direction of closing, and that it must also keep the closing position stable against manual and unauthorized drives on it, however allowing manual operation in an emergency situation, such as for example in the event of a failure in the electric power supply of your motor, or a failure in the motor itself

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En el ámbito preferente de aplicación práctica de la invención, el de los vagones de ferrocarril y similares, es conocida la utilización de puertas correderas, en unos casos con sistemas de accionamiento hidráulico o neumático, y en otros con sistemas de accionamiento eléctrico.In the preferred field of practical application of the invention, that of rail cars and the like, it is known to use sliding doors, in some cases with hydraulic or pneumatic drive systems, and in others with electric drive systems.

Concretamente en este último aspecto son conocidas puertas correderas provistas de una cremallera sobre la que actúa, a través de un desmultiplicador apropiado, el eje de un motor eléctrico que, asistido por finales de carrera, genera los movimientos necesarios y precisos para el desplazamiento de la puerta.Specifically, in this last aspect, sliding doors are known provided with a rack on which it acts, through a Appropriate multiplier, the axis of an electric motor that, assisted by the end of the race, generates the necessary and precise movements for the movement of the door.

Este tipo de transmisión resulta excesivamente "rígido" de manera que es el propio motor, en situación estática, el que actúa simultáneamente como elemento de bloqueo para la puerta tanto en situación de apertura como en situación de cierre, de manera que ante un fallo en la alimentación de corriente la puerta queda inmovilizada en la situación en la que se encuentre, debiendo recurrirse a mecanismos complejos y costosos para llevar a cabo un desacoplamiento manual que permita, por ejemplo, abrir la puerta ante un caso de emergencia.This type of transmission is excessively "rigid" so that it is the motor itself, in a static situation, that simultaneously acts as a blocking element for the door both in the opening and in the closing situation, so that in the event of a failure in the power supply to the door is immobilized in the situation in which it is located, and complex and expensive mechanisms must be used to carry out a manual decoupling that allows, for example, to open the door in case of an emergency.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

El mecanismo que la invención propone, perteneciendo al tipo de los que utilizan como medio de accionamiento un motor eléctrico, resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, de manera que con una estructura simple y eficaz permite, además de un óptimo funcionamiento de la puerta en sentido de apertura y cierre, un perfecto bloqueo de la misma, en posición de cierre, y la posibilidad de desenclavamiento manual, también de una forma sumamente rápida y sencilla, por ejemplo actuando mediante una simple maneta convenientemente dispuesta al efecto.The mechanism that the invention proposes, belonging to the type of those that use an electric motor as the driving means, solves in a completely satisfactory way the problem previously exposed, so that with a simple and efficient structure it allows, in addition to an optimal operation of the door in the direction of opening and closing, a perfect lock of the same, in the closed position, and the possibility of manual unlocking, also in an extremely fast and simple way, for example acting by a simple handle conveniently arranged for this purpose.

Para ello y de forma más concreta en el mecanismo que se preconiza participa un carro, destinado a fijarse a uno de los bordes de la puerta, preferentemente a su borde superior, carro deslizante sobre un perfil soporte, a través de medios de rodadura adecuados, como por ejemplo roldanas debidamente distribuidas, incorporando dicho carro, solidarizada a los extremos del mismo, una correa dentada pasante a través de un juego de tres rodillos, de los que uno de ellos es motriz y los otros dos son tensores, todos ellos montados sobre un soporte fijo al perfil soporte al que se ha hecho mención con anterioridad y, al igual que éste último, solidarizado a la parte fija de la estructura del vagón, recibiendo el rodillo motriz el movimiento, en uno u otro sentido, para el desplazamiento longitudinal de la puerta también en uno u otro sentido, a expensas de un motor establecido también en el propio soporte, todo ello de forma que el accionamiento de dicho motor trae consigo un desplazamiento longitudinal de la correa dentada con respecto al citado soporte, con el consecuente y paralelo desplazamiento de la puerta asociada a la misma.To do this and more specifically in the mechanism that is recommended a car participates, intended to be fixed to one of the edges of the door, preferably at its upper edge, sliding carriage on a support profile, through suitable rolling means, such as, for example, properly distributed sheaves, incorporating said carriage, connected to the ends thereof, a through toothed belt through a set of three rollers, of which one of them is driving and the other two are tensioners, all mounted on a fixed support to the support profile mentioned above and, like the latter, in solidarity with the fixed part of the structure of the car, the driving roller receiving the movement, in one way or another, for the longitudinal displacement of the door also in one way or another, at the expense of an engine also established in the support itself, all in such a way that the driving of said motor entails a longitudinal displacement of the toothed belt with respect to said support, with the consequent and parallel displacement of the door associated with it. At the same time.

De acuerdo con otra de las características de la invención se ha previsto que el estator del motor esté montado con posibilidad de giro sobre el citado soporte y cuente con un accionador que juega en un orificio rasgado de un brazo rematado en una roldana, capacitada para encajar en un alojamiento operativamente establecido en el carro, provocando el automático bloqueo del mismo cuando éste, y consecuentemente la puerta asociada al mismo, llegan a la situación de cierre, de manera que en tal posición límite existe una absoluta imposibilidad de actuar manualmente sobre la puerta, en sentido de apertura, al quedar ésta última bloqueada al soporte, situación de la que se pasa automáticamente a la de desbloqueo al ponerse en funcionamiento el motor eléctrico, por cuanto que al estar bloqueado su rotor se produce un giro de su estator, con lo que éste último actúa a través de su accionador sobre el citado brazo, extrayendo la extremidad operativa del mismo de su alojamiento y produciéndose el desbloqueo del carro, con lo que queda a su vez liberado el rotor del motor, para que éste pueda llevar a cabo la maniobra de apertura.In accordance with another of the features of the invention, it is provided that the motor stator is mounted with the possibility of turning on said support and has an actuator that plays in a torn hole of an arm finished off in a sheave, capable of fitting in an accommodation operatively established in the car, causing the automatic locking of the car when it, and consequently the door associated with it, reach the closing situation, so that in such limit position there is an absolute impossibility of manually acting on the door , in the direction of opening, when the latter is locked to the support, a situation from which it is automatically passed to the unlocking when the electric motor is started, because when its rotor is locked a rotation of its stator occurs, with what the latter acts through its actuator on the aforementioned arm, removing the operative limb of the same from its housing and producing the unlocking of the car, which in turn releases the motor rotor, so that it can carry out the opening maneuver.

Finalmente y de acuerdo con otra de las características de la invención, se ha previsto que con el citado accionador asociado al estator del motor, colabore una leva, capaz también de arrastrar el brazo en sentido de desbloqueo, leva montada basculantemente sobre el soporte y accionable en contra de la tensión de un resorte desde cualquier punto adecuado, como por ejemplo a través de una maneta relacionada con la leva mediante un cable de transmisión, maneta que tan solo mantiene la puerta desbloqueada mientras se encuentra activada, debiendo simultáneamente actuar sobre dicha puerta para conseguir la maniobra de apertura manual de la misma.Finally, and in accordance with another of the characteristics of the invention, it is provided that with the said actuator associated with the motor stator, a cam collaborates, also capable of dragging the arm in the direction of unlocking, cam pivotally mounted on the support and operable against the tension of a spring from any suitable point, such as through a lever related to the cam by means of a transmission cable, handle that only keeps the door unlocked while it is activated, simultaneously acting on said door to get the manual opening maneuver of it.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas puede observarse como el mecanismo para accionamiento de puertas correderas que la invención propone está constituido a partir de un carro (1), que en el ejemplo de realización práctica elegido adopta una trayectoria arqueada, por cuanto que está previsto para una puerta circular, pero que igualmente puede adoptar una configuración rectilínea, concretamente en el caso de que se trate de una puerta recta, pudiendo igualmente acoplarse a un borde horizontal o un borde vertical de la misma, en función del tipo de accionamiento previsto, carro (1) que en cualquier caso y con la colaboración de fijaciones extremas (2), recibe solidariamente a los extremos de una correa dentada (3), que a lo largo de su trayectoria, sensiblemente paralela a la del carro (1) es pasante a través de un juego de tres rodillos, concretamente un rodillo motriz (4), dentado en correspondencia con la correa, y una pareja de rodillos tensores (5-5') que determinan quiebros en la trayectoria de la correa dentada (3), para conseguir una perfecta adaptación de la misma al rodillo motriz (4) y consecuentemente unas óptimas condiciones de transmisión, como se desprende de la observación de la figura 5.In view of the aforementioned figures, it can be seen how the mechanism for actuating sliding doors that the invention proposes is constituted from a carriage (1), which in the example of practical implementation chosen adopts an arcuate path, since it is provided for a circular door, but which can also adopt a rectilinear configuration, specifically in the case of a straight door, and can also be coupled to a horizontal edge or a vertical edge thereof, depending on the type of drive provided, carriage (1) that in any case and with the collaboration of extreme fixings (2), receives jointly at the ends of a toothed belt (3), which along its trajectory, substantially parallel to that of the carriage (1) is through a set of three rollers, specifically a drive roller (4), toothed in correspondence with the belt, and a pair of tension rollers (5-5 ') that they determine breaks in the trajectory of the toothed belt (3), in order to achieve a perfect adaptation thereof to the drive roller (4) and consequently optimum transmission conditions, as can be seen from the observation in Figure 5.

Estos rodillos (4) y (5) están montados sobre un soporte (6) que a su vez es solidario a un perfil soporte (7) que, con la misma configuración que el carro (1), es decir con una configuración arqueada en el ejemplo de realización práctica de las figuras o con una configuración rectilínea en su caso, permite el desplazamiento de dicho carro (1), suspendido del mismo, mediante roldanas (8) preferentemente asistidas por cojinetes.These rollers (4) and (5) are mounted on a support (6) which in turn is integral to a support profile (7) which, with the same configuration as the carriage (1), that is to say with an arched configuration in The practical embodiment of the figures or with a rectilinear configuration, where appropriate, allows the movement of said carriage (1), suspended therefrom, by means of rollers (8) preferably assisted by bearings.

El rodillo motriz (4) recibe el movimiento de un grupo motrizThe driving roller (4) receives the movement of a driving group

(9) en el que participa un motor eléctrico, montado igualmente sobre el soporte (6), de manera que el giro en un determinado sentido del citado motor(9) in which an electric motor participates, also mounted on the support (6), so that the rotation in a certain direction of said motor

(9) provoca el desplazamiento de la puerta asociada al carro (1), también en un determinado sentido, y viceversa.(9) causes the displacement of the door associated with the carriage (1), also in a certain direction, and vice versa.

El motor (9) está montado sobre el soporte (6) de manera que su estator, el correspondiente a la propia referencia (9), es susceptible de girar sobre su rotor, cuando éste último se encuentre en situación de bloqueo, contando dicho estator (9) con un accionador (10) que, a través de un orificio rasgado (11) existente en un brazo (12), actúa sobre éste último, brazo (12) provisto en su extremidad libre de una roldana (13) sobre la que es deslizante el carro (1), pero contando dicho carro con un alojamiento (14) que queda operativamente enfrentado al brazo (12) de situación límite de cierre para la puerta, situación en la que la roldana (13) y consecuentemente la extremidad del brazo (12) se enclava en el alojamiento (14), quedando el mecanismo bloqueado y, consecuentemente, quedando la puerta imposibilitada para una maniobra manual de apertura de la misma. Sin embargo de esta situación de bloqueo se sale automáticamente al ponerse en funcionamiento el motor (9) por cuanto que al estar en dicha posición de bloqueo inmovilizado su rotor, concretamente a través del rodillo dentado (4), se produce el giro de su estator (9) con lo que el accionador (10) asociado a éste último tracciona axialmente del brazo (12), desenclavándolo del carro (1), momento en el que el rotor del motor queda liberado y en el que se inicia la maniobra de apertura de la puerta.The motor (9) is mounted on the support (6) so that its stator, the one corresponding to the reference itself (9), is capable of rotating on its rotor, when the latter is in a locked position, counting said stator (9) with an actuator (10) that, through a torn hole (11) existing in an arm (12), acts on the latter, arm (12) provided at its free end of a sheave (13) on the what is sliding the carriage (1), but said carriage having a housing (14) that is operatively facing the arm (12) of the closing limit situation for the door, situation in which the sheave (13) and consequently the limb of the arm ( 12) is interlocked in the housing (14), the mechanism being locked and, consequently, the door being disabled for a manual opening maneuver thereof. However, this blocking situation automatically exits when the engine (9) is started, because when its rotor is in the locked position, specifically through the toothed roller (4), the rotation of its stator occurs (9) with which the actuator (10) associated with the latter pulls axially from the arm (12), unlocking it from the carriage (1), at which time the motor rotor is released and at which the opening maneuver is initiated of the door.

Se ha previsto no obstante que esta maniobra de desbloqueo pueda realizarse también de forma manual, por ejemplo ante una situación de emergencia en la que el motor (9) se ha quedado sin alimentación eléctrica, a cuyo efecto con el accionador (10) asociado al estator del motor (9) colabora una leva (15) montada basculantemente sobre el propio soporte (6) y desplazable hacia el accionador (10) en contra de la tensión de un resorte (16), de manera que dicha leva (15) es capaz de desplazar longitudinalmente el brazo (12) hacia la situación de desbloqueo, cuando se actúa sobre la extremidad libre (17) de la misma por cualquier medio apropiado, como por ejemplo con la colaboración de un cable y mediante una maneta operativamente establecida al efecto. It is foreseen, however, that this unlocking operation can also be performed manually, for example in an emergency situation in which the motor (9) has run out of power, for which purpose with the actuator (10) associated with the motor stator (9) collaborates a cam (15) mounted tiltingly on the support itself (6) and movable towards the actuator (10) against the tension of a spring (16), so that said cam (15) is capable of longitudinally moving the arm (12) towards the unlocking situation, when acting on the free end (17) thereof by any appropriate means, such as with the collaboration of a cable and by means of a handle operatively established for that purpose .
