MECANISMO DE SUSPENSIÓN PARA PUERTAS ENCAJABLES DESLIZANTES SUSPENSION MECHANISM FOR SLIDING LID DOORS
D E S C R I P C I Ó ND E S C R I P C I Ó N
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a unos perfeccionamientos introducidos en el mecanismo de suspensión para puertas encajables deslizantes que constituye el objeto de la patente de invención 9501451, perfeccionamientos orientados a permitir una fácil regulación en el mecanismo, con la que es posible llevar a cabo un perfecto ajuste en altura de la puerta o puertas asociadas a dicho mecanismo.The present invention relates to improvements introduced in the suspension mechanism for sliding sliding doors that constitutes the object of the invention patent 9501451, improvements oriented to allow easy regulation in the mechanism, with which it is possible to carry out a perfect height adjustment of the door or doors associated with said mechanism.
El mecanismo es aplicable a puertas de las utilizadas en vagones ferroviarios y similares, manteniendo la eficacia funcional del mismo y manteniendo prácticamente la misma simplicidad.The mechanism is applicable to doors used in railway cars and the like, maintaining its functional efficiency and maintaining practically the same simplicity.
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 requiere de unas prestaciones similares, las puertas abatibles crean diferentes tipos de problemas que han determinado que actualmente se encuentren totalmente en desuso, resultando mucho más prácticas las puertas deslizantes.Specifically in the field of railway cars, as well as in other practical cases in which similar benefits are required, the swing doors create different types of problems that have determined that they are currently totally disused, the doors being much more practical sliders
Para la movilidad de dichas puertas deslizantes existen diferentes soluciones que van, de 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 encajables, pasando por puertas deslizantes en el seno de una doble pared establecida en el propio vagón.For the mobility of said sliding doors there are different solutions that go from a simple exterior slide through which said doors move parallel to the wall of the car or element in question, to doors that in addition to sliding are adjustable, passing through doors sliders within a double wall established in the car itself.
Indudablemente las puertas encajables y deslizantes son las más idóneas en el ámbito ferroviario, por cuanto que, como es obvio, una puerta deslizante no permite establecer un cierre perfectamente ajustado, que si que puede conseguirse cuando la puerta, tras su movimiento deslizante que la sitúa en posición de cierre, describe un ligero desplazamiento frontal encajando en el hueco a cerrar, donde puede presionar sobre la correspondiente junta.Undoubtedly, the sliding and sliding doors are the most suitable in the railway field, since, as is obvious, a sliding door does not allow to establish a perfectly adjusted closure, which can be achieved when the door, after its sliding movement that places it In the closed position, it describes a slight frontal displacement fitting into the hole to be closed, where you can press on the corresponding joint.
En la actualidad las puertas encajables deslizantes quedan normalmente suspendidas de una guía horizontal y superior, establecida en la cara externa del vagón o elemento de que se trate, que permite el desplazamiento de la puerta hacia la situación de enfrentamiento al hueco a cerrar, posición en la que las guías citadas desembocan en cortas guías perpendiculares a las anteriores, que permiten el definitivo desplazamiento frontal de la puerta para cierre total de la misma.At present, the sliding sliding doors are normally suspended from a horizontal and upper guide, established on the outer face of the car or element in question, which allows the door to move towards the situation of facing the hole to be closed, position in that the mentioned guides lead to short guides perpendicular to the previous ones, which allow the definitive frontal displacement of the door for its total closing.
Esto supone una problemática con una doble vertiente, por un lado las guías longitudinales resultan visibles en situación de cierre, repercutiendo negativamente en la estética del vagón o elemento de que se trate, a la vez que constituyen elementos que rompen la aerodinámica del mismo, pudiéndose producir ruidos, sobre todo cuando el tren se mueve a alta velocidad, mientras que por otro lado las cortas guías perpendiculares a las anteriores obligan a unos ajustes muy precisos, que consecuentemente repercuten negativamente tanto en el momento de construcción de la puerta como en el posterior mantenimiento de la misma, creando además problemas de manipulación cuando el accionamiento de dichas puertas es automático, como es habitual .This is a problem with a double slope, on the one hand the longitudinal guides are visible in a closed situation, negatively affecting the aesthetics of the wagon or element in question, while constituting elements that break the aerodynamics of the car, being able to produce noises, especially when the train moves at high speed, while on the other hand the short guides perpendicular to the previous ones require very precise adjustments, which consequently have a negative impact on both the moment of construction of the door and the subsequent maintenance thereof, also creating handling problems when the operation of said doors is automatic, as is usual
La problemática anteriormente expuesta se solventa con el mecanismo de la patente de invención 9501451, en el que participa una guía telescópica, a base de varios tramos deslizantes entre sí, a uno de los cuales, al tramo terminal, se fija la puerta en cuestión, mientras que al tramo inicial y con la colaboración de soportes extremos, se fijan articuladamente una pareja de bieletas que a su vez se unen articuladamente a otros soportes solidarizados a la estructura fija del vagón o elemento de que se trate, de manera que a través de estas bielas y con la colaboración de medios de accionamiento apropiados, el conjunto constituido por la guía telescópica y la puerta es eneajable y desencajable del hueco de la misma, y en situación de desencajamiento la puerta puede desplazarse lateralmente entre las situaciones límite de apertura y cierre, mediante expansión y retracción de la guía telescópica.The aforementioned problem is solved with the mechanism of the invention patent 9501451, in which a telescopic guide participates, based on several sliding sections with each other, to one of which, to the terminal section, the door in question is fixed, while to the initial section and with the collaboration of extreme supports, a pair of connecting rods are articulated that in turn articulate themselves to other supports in solidarity with the fixed structure of the car or element in question, so that through These cranks and with the collaboration of appropriate actuation means, the assembly constituted by the telescopic guide and the door is removable and detachable from the hollow of the same, and in a situation of disengagement the door can move laterally between the opening and closing limit situations , by expansion and retraction of the telescopic guide.
En un primer certificado de adición a dicha patente de invención, se describen unas mejoras que permiten suspender, de un mismo mecanismo, dos puertas que trabajan en combinación, encajables en un mismo hueco, común a ambas, del que resultan también simultáneamente desencajables para poder deslizarse en sentidos contrarios.In a first certificate of addition to said patent of invention, some improvements are described that allow to suspend, of the same mechanism, two doors that work in combination, fit in the same hole, common to both, from which they are also simultaneously detachable to be able to slide in opposite directions.
Tanto en uno como en otro caso y al objeto de corregir posibles errores o desajustes de montaje, los brazos de suspensión deben actuar como elementos reguladores de altura para la puerta o puertas, en orden a ajustarías convenientemente con respecto al hueco del vagón.In both cases, and in order to correct possible errors or mounting mismatches, the suspension arms must act as height adjustment elements for the door or doors, in order to adjust accordingly with respect to the carriageway.
DESCRIPCIÓN DE LA INVENCIÓN Los perfeccionamientos que la invención propone constituyen una solución simple y totalmente eficaz para llevar a cabo dicha regulación en altura.DESCRIPTION OF THE INVENTION The improvements proposed by the invention constitute a simple and totally effective solution for carrying out said height adjustment.
Para ello y de forma más concreta, dichos perfeccionamientos consisten en montar cada una de las bieletas del mecanismo sobre el correspondiente soporte ahorquillado de la cornisa interior de la zona superior del hueco del vagón o elemento de que se trate, a través de un eje especial, al que dicha bieleta está convenientemente enchavetada, eje que se materializa en un tornillo convenientemente roscado a una de las ramas transversales del soporte ahorquillado, de manera que al actuar sobre la cabeza del tornillo, en uno u otro sentido, éste actúa a su vez como un husillo que se desplaza axialmente en sentido vertical, arrastrando consigo a la correspondiente bieleta y, consecuentemente, provocando la elevación o descenso de la puerta o puertas, para regulación posicional de las mismas.To do this and more specifically, these improvements consist of mounting each of the linkers of the mechanism on the corresponding bracketed support of the inner cornice of the upper area of the carriageway or element in question, through a special axis , to which said link is conveniently keyed, an axis that materializes in a screw conveniently threaded to one of the transverse branches of the bracketed support, so that when acting on the head of the screw, in one way or another, it acts in turn as a spindle that moves axially vertically, dragging the corresponding linkage with it and, consequently, causing the raising or lowering of the door or doors, for positional regulation thereof.
De acuerdo con otra de las características de la invención se ha previsto que el citado eje especial esté asistido por un tornillo prisionero que, tras la conveniente regulación del cerramiento a término de la maniobra de montaje del mismo, inmoviliza definitivamente el sistema.According to another of the characteristics of the invention, it is provided that said special axis is assisted by a captive screw which, after the convenient adjustment of the closing at the end of the assembly maneuver thereof, permanently immobilizes the system.
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, una hoja única de planos en la que con carácter ilustrativo y no limitativo y en su única figura, se ha representado en alzado lateral y en sección parcial una de las bielas del mecanismo, con sus correspondientes soportes y accesorios, de acuerdo con los perfeccionamientos objeto del presente certificado de adición.To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a single sheet of plans is attached as an integral part of it, in which it is illustrative and non-limiting and in its only figure, it has been represented in side elevation and in partial section a of the cranks of the mechanism, with their corresponding supports and accessories, in accordance with the improvements object of this certificate of addition.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
En la citada figura se ha referenciado con (1) el soporte ahorquillado al que ha de fijarse la guía telescópica, no representada, por ejemplo según los puntos de fijación representados esquemáticamente con las líneas discontinuas (2) , estableciéndose entre las ramas laterales de este soporte ahorquillado (1) un eje (3) sobre el que gira o bascula la bieleta (4) , con interposición de un cojinete (5) , a la vez que dicha bieleta (4) , por su otro extremo y a través de otro cojinete (6) , gira sobre un eje (7) montado a su vez sobre un soporte ahorquillado (8) , destinado a su vez a fijarse, por atornillamiento o por cualquier otro medio, según las líneas esquemáticas (9) , a una cornisa interior operativamente establecida en la zona superior del hueco del vagón o elemento de que se trate.In the aforementioned figure, the bracketed support to which the telescopic guide is to be attached, not shown, has been referenced, for example, according to the fixing points represented schematically with the broken lines (2), being established between the lateral branches of this bracketed support (1) an axis (3) on which the connecting rod (4) rotates or tilts, with interposition of a bearing (5), at the same time as said connecting rod (4), at its other end and through another bearing (6), rotates on a shaft (7) mounted in turn on a bracketed support (8), in turn intended to be fixed, by screwing or by any other means, according to the schematic lines (9), to an inner cornice Operationally established in the upper area of the carriageway or element in question.
Pues bien, a partir de esta estructuración básica y convencional, los perfeccionamientos de la invención se centran en el hecho de que la extremidad de la biela (4) correspondiente al soporte (8) de fijación al vagón o elemento de que se trate, está enchavetada al citado ejeWell, from this basic and conventional structuring, the improvements of the invention focus on the fact that the end of the connecting rod (4) corresponding to the support (8) for fixing to the car or element in question, is keyed to the aforementioned axis
(7) , de manera que puede bascular libremente con respecto a él pero queda absolutamente inmovilizada en sentido axial, enchavetamiento que se lleva a cabo mediante un casquillo inferior (10) y una tuerca superior (11) , tuerca que se fija al eje (7) por cuanto que éste es un eje especial, con un sector (12) roscado, a través del que recibe a la citada tuerca (11) de enchavetamiento de la biela (4) y a través del que el propio eje especial(7), so that it can swing freely with respect to it but it is absolutely immobilized axially, keyed that is carried out by means of a lower bushing (10) and an upper nut (11), nut that is fixed to the shaft ( 7) because this is a special shaft, with a threaded sector (12), through which it receives said crank nut (11) from the connecting rod (4) and through which the special shaft itself
(7) se solidariza a la rama superior del soporte ahorquillado (8) , concretamente en un orificio roscado (13) operativamente practicado en esta última.(7) solidarity with the upper branch of the support bracketing (8), specifically in a threaded hole (13) operatively practiced in the latter.
El casquillo inferior (10) juega loco en un orificio (14) de la rama inferior del soporte (8) , y es atravesado por un sector (15) del eje (7) de diámetro reducido, previo a la cabeza (16) de accionamiento del mismo, de manera que al actuar sobre dicha cabeza (16) el eje especial (7) gira conjuntamente con el casquillo (10), la tuerca (11) y el sector interno y correspondiente de los rodamientos (6) , actuando como un husillo sobre la tuerca (13) , que se desplaza verticalmente, arrastrando consigo a la bieleta (4) , que de esta manera puede variar su altura de trabajo con respecto al soporte (8) , permitiendo, consecuentemente, regular la posición en altura de la puerta o puertas asociadas a dicha biela (4) y a su gemela.The lower bushing (10) plays crazy in a hole (14) of the lower support branch (8), and is crossed by a sector (15) of the shaft (7) of reduced diameter, prior to the head (16) of actuation thereof, so that when acting on said head (16) the special shaft (7) rotates together with the bushing (10), the nut (11) and the internal and corresponding sector of the bearings (6), acting as a spindle on the nut (13), which moves vertically, dragging along the connecting rod (4), which in this way can vary its working height with respect to the support (8), allowing, consequently, to adjust the height position of the door or doors associated with said connecting rod (4) and its twin.
Obviamente esta maniobra de regulación se efectúa normalmente una sola vez, en el momento del montaje de la puerta o puertas, y para evitar que con el tiempo se produzcan desajustes en el mecanismo, se ha previsto que sobre una de las ramas laterales del soporte (8) , preferentemente sobre la rama inferior, se establezca un tornillo prisionero (17) que inmoviliza el eje (7) , manteniendo absolutamente estable el mecanismo.Obviously, this regulation maneuver is normally carried out only once, at the time of mounting the door or doors, and to avoid that over time there are mismatches in the mechanism, it is foreseen that on one of the lateral branches of the support ( 8), preferably on the lower branch, a captive screw (17) is established that immobilizes the shaft (7), keeping the mechanism absolutely stable.
No se considera necesario hacer más extensa esta descripción para que cualquier experto en la materia comprenda el alcance de la invención y las ventajas que de la misma se derivan.It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom.
