Abstract

The specific object of the suspension mechanism is to ensure, during the nesting and unesting operations of the door (1), a movement of the door which is perfectly perpendicular to the general closing plane, in order to improve the conditions of said closing operation. This is obtained by fixing the telescopic guide (3) for the sliding of the door (1) to a support (5) from which extend integrally a pair of shafts (6) projecting horizontally towards the inside of the carriage (4) or like element and which are conventionally guided by a pair of sheaves (8) and (9) or by any other appropriate means. The longitudinal motion of said shafts is synchronized so as to avoid the nodding of the doors or out-of-adjustment of one door with respect to the other when it concerns two complementary doors.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención se refiere a un mecanismo de suspensión para puertas correderas eneajabíes, como por ejemplo las utilizadas en vagones ferroviarios y similares, puertas que en situación de cierre quedan encajadas en la carrocería de los vagones, estableciendo continuidad superficial externa en los mismos, al objeto de mejorar las condiciones de penetración aerodinámica, y que para su apertura deben ser inicialmente desencajadas de dicha carrocería, para poder efectuar seguidamente el deslizamiento longitudinal necesario para su apertura.The present invention relates to a suspension mechanism for sliding doors enneajabíes, such as those used in rail cars and the like, doors that are locked in the body of the wagons, establishing external surface continuity in them, to in order to improve the conditions of aerodynamic penetration, and that for its opening they must be initially disengaged from said body, in order to be able to subsequently carry out the longitudinal sliding necessary for its opening.

El objeto de la invención es mejorar las condiciones de encajamiento de la puerta en la carrocería, para un mejor cierre.The object of the invention is to improve the conditions of engagement of the door in the body, for a better closure.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Específicamente en el ámbito de los vagones ferroviarios, así como en otros supuestos prácticos en los que se requieren prestaciones similares, las puerta abatibles crean problemas amplios y variados que hacen que en la actualidad se encuentren totalmente en desuso, habiendo sido sustituidas por puertas deslizantes o de corredera.Specifically in the field of railway wagons, as well as in other practical cases where similar performance is required, the swing doors create wide and varied problems that currently make them totally obsolete, having been replaced by sliding doors or Sliding

Para la movilidad de estas puertas deslizantes, existen diferentes soluciones que van, desde una simple corredera exterior por la que dichas puertas se desplazan paralelamente a la pared del vagón o elemento de que se trate, hasta puertas que además de deslizantes son eneajabíes, como las anteriormente citadas.For the mobility of these sliding doors, there are different solutions that range from a simple external sliding through which said doors move parallel to the wall of the car or item in question, to doors that in addition to sliding are eneajabíes, as the aforementioned.

Concretamente una de las soluciones utilizadas como más idónea para este tipo de puertas, consiste en utilizar una guía telescópica horizontal y superior, de la que queda suspendida la puerta, guía que además de ser susceptible de alargarse y acortarse telescópicamente, es susceptible de desplazarse en su conjunto, cuando está replegada, en sentido frontal, al objeto de establecer las maniobras de encajamiento y desencajamiento de la misma, del correspondiente alojamiento de la carrocería del vagón.Specifically, one of the solutions used as most suitable for this type of doors is to use a horizontal and upper telescopic guide, from which the door is suspended, a guide that, in addition to being able to lengthen and shorten telescopically, is capable of moving in as a whole, when it is folded, in the frontal direction, in order to establish the maneuvering and disengagement of the same, of the corresponding housing of the car body.

Sin embargo este desplazamiento frontal lo es nada más desde el punto de vista teórico, ya que en la práctica se consigue mediante una pareja de bielas, que por uno de sus extremos se unen articuladamente a la guía telescópica, mientras que por otro lo hacen a puntos fijos de la carrocería del vagón. Ello supone que, en el movimiento de basculación de las bielas, la puerta describa una trayectoria arqueada, es decir que el desplazamiento de la misma con respecto al vagón no es perfectamente perpendicular al plano general de dicho vagón en el que juega la puerta, sino que es realmente oblicuo y con trayectoria arqueada. Consecuentemente el alojamiento de la carrocería del vagón debe estar concebido, diseñado y dimensionado para permitir este movimiento sesgado de las puertas, lo que supone una complejidad estructural en el cierre sensiblemente mayor que si dichas puertas llevasen a cabo la maniobra de encajamiento y desencajamiento con trayectorias perfectamente perpendiculares al plano general de su embocadura en la carrocería del vagón.However, this frontal displacement is nothing more from the theoretical point of view, since in practice it is achieved by a pair of connecting rods, which at one end join the telescopic guide, while on the other they do fixed points of the car body. This means that, in the swinging movement of the connecting rods, the door describes an arched trajectory, that is to say that its displacement with respect to the car is not perfectly perpendicular to the general plane of said car in which the door plays, but which is really oblique and with an arched trajectory. Consequently, the car body housing must be designed, designed and sized to allow this biased movement of the doors, which implies a structural complexity in the closure significantly greater than if said doors carried out the engagement and disengagement maneuver with trajectories perfectly perpendicular to the general plane of your mouthpiece in the car body.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

El mecanismo de suspensión que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, permitiendo, de acuerdo con el objetivo fundamental de dicha invención, que la puerta corredera realice sus maniobras de encajamiento y desencajamiento con un movimiento perfectamente perpendicular con respecto al plano general de encajamiento de la misma.The suspension mechanism proposed by the invention fully and satisfactorily resolves the above-mentioned problem, allowing, in accordance with the fundamental objective of said invention, that the sliding door performs its engagement and disengagement maneuvers with a perfectly perpendicular movement with respect to the plane general fitting of it.

Para ello, de forma más concreta y a partir de una estructuración convencional según la cual la pareja de puertas que normalmente establecen en su conjunto el cerramiento de un determinado vano, están montadas sobre respectivas guías telescópicas, cada una de estas guías es solidaria a un soporte, al que son solidarios a su vez una pareja de ejes, que emergen perpendicular ente de las zonas extremas del citado soporte y que son deslizantes con respecto a la carrocería del vagón o elemento de que se trate en la dirección de sus propios ejes, es decir en sentido perfectamente perpendicular al plano de cierre.To do this, more concretely and from a conventional structuring according to which the pair of doors that normally establish as a whole the closing of a certain opening, are mounted on respective telescopic guides, each of these guides is integral with a support , to which a pair of axes are in solidarity, which emerge perpendicularly from the extreme areas of said support and which are sliding with respect to the body of the car or element in question in the direction of its own axes, is say perfectly perpendicular to the closing plane.

De forma más concreta se ha previsto que cada uno de estos ejes sea guiado por un par de roldanas, contando además dicho eje con un tope limitador de recorrido que, obviamente, limita el desplazamiento de la puerta en sentido de desencajamiento de la misma.More specifically, it is provided that each of these axes is guided by a pair of sheaves, said axis also having a travel limit stop that obviously limits the movement of the door in the direction of disengagement thereof.

De acuerdo con otra de las características de la invención y al objeto de conseguir un perfecto sincronismo tanto para los dos ejes que participan en una misma puerta, como en su caso para los dos ejes de una puerta con respecto a los de la complementaria, se ha previsto que cada uno de estos ejes incorpore, en correspondencia con la generatriz de apoyo de una de las roldanas, una cremallera, mientras que la roldana correspondiente incorpora un dentado complementario, quedando las respectivas roldanas de los diferentes ejes relacionadas entre sí mediante un eje común que las fuerza a un movimiento sincronizado, lo que equivale a un movimiento también sincronizado de los correspondientes ejes a través de las respectivas cremalleras.According to another of the characteristics of the invention and in order to achieve a perfect synchronism both for the two axes that participate in the same door, as in its case for the two axes of a with respect to those of the complementary one, it is planned that each one of these axes incorporates, in correspondence with the support generatrix of one of the sheaves, a zipper, while the corresponding sheave incorporates a complementary teeth, leaving the respective sheaves of the different axes related to each other by means of a common axis that forces them to a synchronized movement, which is equivalent to a movement also synchronized of the corresponding axes through the respective zippers.

No obstante esta solución puede ser sustituida por una barra de torsión convenientemente solidarizada a la extremidad posterior y libre de los ejes, barra que los fuerza, de una forma análoga, a una movilidad paralela y sincronizada.However, this solution can be replaced by a torsion bar conveniently attached to the rear end and free of the shafts, which forces them, in a similar way, to a parallel and synchronized mobility.

DESCRIPCIÓN DE LOS DIBUJOSDESCRIPTION OF THE DRAWINGS

Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña a la presente memoria descriptiva, como parte integrante de la misma, un juego de dibujos en donde con carácter ilustra- tivo y no limitativo, se ha representado lo siguiente:To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part thereof, with an illustrative character and not limiting, the following has been represented:

La figura 1.- Muestra un detalle parcial en sección transversal de un vagón, a nivel de la zona de suspensión de una de sus puertas, en el que se observa la estructura del mecanismo de suspensión que constituye el objeto de la presente invención.Figure 1.- It shows a partial cross-sectional detail of a car, at the level of the suspension area of one of its doors, in which the structure of the suspension mechanism constituting the object of the present invention is observed.

La figura 2.- Muestra un detalle en sección transversal del conjunto representado en la figura anterior, de acuerdo con la línea de corte A-B de dicha figura.Figure 2.- Shows a cross-sectional detail of the assembly represented in the previous figure, in accordance with the cut line AB of said figure.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de estas figuras y especialmente de la figura 1, puede observarse cómo la puerta corredera (1), a través de un anclaje (2) apropiado, queda suspendida de una guía telescópica (3) capacitada para quedar encajada en el seno de la carrocería (4) del vagón, en la situación de cierre para la puerta representada en la figura 1, o de desplazarse transversalmente hacia afuera, para situarse fuera de dicha carrocería (4), permitiendo con su extensión el desplazamiento longitudinal de la puerta (1) necesario para la apertura de la misma.In view of these figures and especially of figure 1, it can be seen how the sliding door (1), through an appropriate anchor (2), is suspended from a telescopic guide (3) capable of being fitted within the body (4) of the car, in the closed situation for the door shown in figure 1, or to move transversely outwards, to be located outside said body (4), allowing with its extension the longitudinal displacement of the door ( 1) necessary for opening it.

Pues bien, a partir de esta estructuración básica y convencional, el mecanismo de la invención centra sus características en el hecho de que el módulo de la guía telescópica (3) contrapuesto al de fijación de la puerta (1) , es solidario a un soporte (5) , alargado en correspondencia con la propia guía (3) , al que a su vez son solidarios cerca de sus extremos sendos ejes (6) que, fijados perpendicularmente al soporte (5) , se proyectan horizontalmente hacia el interior del vagón (4), rematándose por su extremidad libre en sendos topes (7) , de los que se hablará seguidamente.Well, from this basic and conventional structuring, the mechanism of the invention focuses its characteristics on the fact that the telescopic guide module (3), opposed to the door fixing (1), is integral with a support (5), elongated in correspondence with the guide itself (3), which in turn are integral with their ends, two axes (6) that, fixed perpendicularly to the support (5), project horizontally towards the interior of the car ( 4), finishing off by its free end in two stops (7), which will be discussed next.

Estos ejes (6) , destinados a sustentar la guía telescópica (3) y, a través de la misma, a la puerta deslizante (1) , se relacionan con el vagón (4) o elemento de que se trate, cada uno de ellos, a través de una pareja de roldanas (8) y (9) , de periferia acanalada en correspondencia con la curvatura del eje (6), una situada inferiormente, la referenciada con (8) , en las proximidades del soporte (5) , mientras que la otra, la referenciada con (9) , se sitúa superiormente y en situación considerablemente más alejada, al objeto de absorber los esfuerzos tendentes a la basculación del eje (6), generados por el propio peso de la puerta (1).These axes (6), intended to support the telescopic guide (3) and, through it, to the sliding door (1), are related to the carriage (4) or element in question, each of them , through a pair of rollers (8) and (9), with a grooved periphery corresponding to the curvature of the shaft (6), one located inferiorly, the one referenced with (8), in the vicinity of the support (5) while the other, the referenced with (9), it is located superiorly and in a considerably more remote situation, in order to absorb the stresses towards the axis (6), generated by the weight of the door (1).

La roldana supero-interior (9) actúa, además de como medio de guiado para el eje (6) , como tope limitador de recorrido axial para dicho eje (6) , al incidir sobre la misma el tope (7) solidarizado a la extremidad libre de dicho eje (6) , tope que no obstante puede incidir, para limitar dicho movimiento, sobre cualquier otro elemento fijo de la estructura del vagón (4) .The supero-inner sheave (9) acts, in addition to guiding means for the axis (6), as an axial travel limit stop for said axis (6), when the stop (7) attached to the extremity falls on it free of said axle (6), butt that can nevertheless influence, to limit said movement, on any other fixed element of the structure of the car (4).

De esta manera y a partir de la situación de cierre representada en la figura 1, la puerta (1) es susceptible de desplazarse hacia afuera, en un movimiento perfectamente perpendicular al plano general de cierre, merced al desplazamiento de su pareja de ejes (6) sobre las correspondientes parejas de roldanas (8) y (9) , hasta una situación límite definida por el tope (7) en la que la guía telescópica (3) se sitúa totalmente por fuera de la carrocería (4) del vagón, quedando en condiciones de permitir el desplazamiento transversal de la puerta (1) , para la correspondiente maniobra de apertura, estableciéndose obviamente para la maniobra de cierre una funcionalidad antagónica.In this way and from the closing situation represented in figure 1, the door (1) is capable of moving outwards, in a movement perfectly perpendicular to the general closing plane, thanks to the movement of its pair of axes (6) on the corresponding pairs of rollers (8) and (9), up to a limit situation defined by the stop (7) in which the telescopic guide (3) is located completely outside the body (4) of the car, remaining in conditions allowing the transverse movement of the door (1), for the corresponding opening maneuver, obviously establishing an antagonistic functionality for the closing maneuver.

La puerta (1) o en su caso la pareja de puertas (1) complementarias, serán accionadas por cualquier medio empujador adecuado, como por ejemplo un circuito neumático que actúe, por ejemplo, sobre el soporte (5) , empujándolo o traccionando del mismo. Pues bien, en este sentido y al objeto de evitar posibles cabeceos de una puerta o desajustes en la movilidad de una puerta con respecto a su complementaria, se ha previsto que los diferentes ejes (6) se muevan perfectamente sincronizados. En este sentido cada eje (6) puede estar dotado de una cremallera (10), por ejemplo sobre la generatriz superior de apoyo de la roldana (9) , contando dicha roldana (9) con un dentado (11) complementario, y estando las roldanas (9) correspondientes a los diferentes ejes (6) de la puerta o puertas (1) , sólidamente unidas entre sí a través de un eje común (12) , que las fuerza a un movimiento sincronizado, de manera que resulta imposible que alguno de estos ejes (6) se desfase en su movimiento de avance o retroceso longitudinal con respecto a los restantes del grupo.The door (1) or, if applicable, the pair of complementary doors (1), will be operated by any suitable pushing means, such as a pneumatic circuit that acts, for example, on the support (5), pushing or pulling it . Well, in this regard and in order to avoid possible headings of a door or mismatches in the mobility of a door with respect to its complement, it is expected that different axes (6) move perfectly synchronized. In this sense, each axis (6) can be provided with a rack (10), for example on the upper generatrix of the sheave (9), said sheave (9) counting on a complementary teeth (11), and the rollers (9) corresponding to the different axes (6) of the door or doors (1), solidly joined together through a common axis (12), which forces them to a synchronized movement, so that it is impossible for any of these axes (6), it is offset in its longitudinal forward or backward movement with respect to the rest of the group.

No obstante y como anteriormente se ha dicho, esta sincronización en el movimiento de los diferentes ejesHowever and as previously stated, this synchronization in the movement of the different axes

(6) , puede realizarse también mediante una barra de torsión convenientemente solidarizada a la extremidad posterior y libre de los mismos.(6), it can also be carried out by means of a torsion bar conveniently attached to the posterior end and free of them.

En cualquier caso se consigue, de acuerdo con el objetivo fundamental de la invención, que frente al movimiento sesgado de las puertas eneajabíes convencionales, para su desacopla iento de la carrocería del vagón o elemento de que se trate, con el mecanismo de la invención la maniobra de desencajamiento, así como la de posterior encajamiento durante el cierre, se realizan con una trayectoria para la puerta perfectamente perpendicular al plano de cierre y, en consecuencia, en condiciones óptimas para dicho cierre.In any case it is achieved, in accordance with the fundamental objective of the invention, that in the face of the biased movement of the conventional enneajabí doors, for its decoupling of the body of the car or element in question, with the mechanism of the invention Disengagement maneuver, as well as subsequent engagement during closing, are carried out with a path for the door perfectly perpendicular to the closing plane and, consequently, under optimal conditions for said closure.
