ANTEDECENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Dentro del estado de la técnica es sabido que existe un número amplio y variado de tipologías de marcos, sin embargo, generalmente no son polivalentes, es decir, la fabricación de las series de puertas abatibles debe hacerse por separado de las plegables, además presentan inconvenientes cuando no disponen de mecanismos de regulación. Algunos de estos modelos tampoco disponen de marco, lo que es preciso colocar los herrajes y accesorios frontalmente sobre las mismas puertas, lo que va en detrimento de la estética y aspecto de las mismas.Within the state of the art it is known that there is a wide and varied number of types of frames, however, they are generally not polyvalent, that is, the manufacture of the series of folding doors must be done separately from the collapsible ones, besides they have drawbacks when they do not have regulatory mechanisms. Some of these models also have no frame, which is necessary to place the fittings and accessories directly on the same doors, which is detrimental to the aesthetics and appearance of them.

Se conoce lo divulgado en los documentos ES1043089U y ES1070603U donde se describen unas tipologías de marcos para puertas que contienen características generales similares, sin embargo, en la presente invención se realizan modificaciones respecto de estos sistemas que optimizan el comportamiento general del conjunto, en concreto se mejora el abatimiento de los marcos introduciendo unos elementos más robustos y resistentes que protegen al conjunto de posibles roturas; y además se mejora la estructura del marco para evitar rozamientos con las guías debido a la inclusión de un eje cilíndrico con unas modificaciones en cuanto a su longitud que a continuación se detallan.It is known what is disclosed in documents ES1043089U and ES1070603U where some typologies of door frames are described that contain similar general characteristics, however, in the present invention modifications are made with respect to these systems that optimize the general behavior of the set, in particular improves the folding of the frames by introducing more elements robust and resistant that protect the set of possible breaks; and in addition, the structure of the frame is improved to avoid friction with the guides due to the inclusion of a cylindrical shaft with some modifications in its length that are detailed below.

Por tanto, habida cuenta de los problemas técnicos de esta tipología de estructuras y de los antecedentes conocidos dentro del estado de la técnica, las modificaciones que se introducen en la presente invención perfeccionan la óptima funcionalidad de estos tipos de marcos plegables y abatibles para muebles.Therefore, taking into account the technical problems of this type of structures and the known background within the state of the art, the modifications introduced in the present invention perfect the optimum functionality of these types of collapsible and collapsible frames for furniture.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

El marco plegable y abatible objeto de la presente invención está dirigido a resolver la problemática anteriormente expuesta, además de presentar una nueva tipología de marco autónomo y único con todas las disposiciones incorporadas, y colocando los accesorios correspondientes se hace fácil la adaptación, tanto el marco para puerta abatible como plegable de muebles, manteniendo la posibilidad de colocar el paño u hoja de la puerta con los materiales y decorativos deseados.The foldable and collapsible frame object of the present invention is aimed at solving the aforementioned problems, in addition to presenting a new typology of autonomous and unique frame with all the provisions incorporated, and placing the corresponding accessories makes the adaptation easy, both the frame for folding door as folding furniture, maintaining the possibility of placing the cloth or sheet of the door with the desired materials and decorative.

Otra particularidad de la invención es que es de montaje muy fácil, pues además de disponer de pocas piezas, estas son repetitivas, ya que comprende dos largueros verticales iguales, sobre los que se acoplan sendos travesaños horizontales, también iguales entre sí, todos ellos conexionados en sus esquinas en la formación de sus escuadras, tanto superiores como inferiores, mediante una carcasa o pieza de unión que dispone de unas reglillas en sus laterales en forma de cola de milano, que se une con los perfiles verticales; mientras que una reglilla de las características anteriores, dispuesta sobre planta de la carcasa se fija sobre los perfiles horizontales, además estos perfiles horizontales llevan una doblez en toda su longitud que encaja con una hendidura que lleva la carcasa, completando la constitución del marco.Another particularity of the invention is that it is very easy to assemble, since apart from having few parts, these are repetitive, since it comprises two equal vertical beams, on which are coupled horizontal crossbars, also equal to each other, all connected in its corners in the formation of its brackets, both upper and lower, by means of a casing or piece of union that has some projections on its sides in the form of a dovetail, which joins the vertical profiles; while a reglilla of the above characteristics, arranged on the floor of the housing is fixed on the horizontal profiles, in addition these horizontal profiles have a fold over its entire length that fits with a slit that carries the housing, completing the frame constitution.

La carcasa tiene una disposición antagónica simétrica, lo que posibilita el montaje en cualquiera de las cuatro esquinas, disponiendo en su frente de unos pequeños mamelones roscados sobre los que se fijan unos tornillos que aprietan sobre los perfiles tanto verticales como horizontales.The housing has a symmetrical antagonistic disposition, which makes possible the assembly in any of the four corners, having in its front of small threaded mamelons on which are fixed screws that tighten on the profiles both vertical and horizontal.

Estas carcasas constituyen la base para el montaje de los accesorios de deslizamiento y giro en el montaje para puertas plegables, montadas dos a dos y unidas por sendas bisagras e igualmente con el montaje de los accesorios correspondientes, forman las puertas abatibles individualmente, que pivotan o giran sobre un eje cilíndrico en la que su extremo está roscado disponiendo de unos planos, de forma, que alojado verticalmente sobre la parte central de la carcasa, impide su giro, mientras que una tuerca interpuesta entre ellos, rosca sobre el eje, lo que permite situarlo en la altura correcta funcional, finalmente, un pequeño tornillo roscado sobre el frontal de la carcasa y posicionado sobre el frente de los planos del eje roscado, le dan un carácter fijo con absoluta seguridad. Este eje cilíndrico previamente descrito se alarga y se diseña con una longitud tal que evita que llegue a rozar la puerta en la guía inferior. These housings form the basis for the assembly of the sliding and pivoting accessories in the assembly for folding doors, mounted two by two and joined by respective hinges and also with the assembly of the corresponding accessories, they form the hinged doors individually, pivoting or they rotate on a cylindrical axis in which their end is threaded, having some planes, of shape, that lodged vertically on the central part of the housing, prevents its rotation, while a nut interposed between them, threaded on the shaft, which allows to place it at the correct functional height, finally, a small screw threaded on the front of the housing and positioned on the front of the planes of the threaded shaft, they give a fixed character with absolute security. This previously described cylindrical shaft is lengthened and designed with a length such that it prevents it from rubbing against the door in the lower guide.

Cuando se trata de muebles con puertas plegables, el montaje se hace por pares, donde se articulan en su centro por unas bisagras mientras que, en un extremo, se colocan los accesorios anteriormente descritos sobre la puerta abatible, y en el extremo opuesto de la otra puerta, se le acopla verticalmente a la carcasa, un eje hueco, introducido sobre uno de los alojamientos que dispone la propia carcasa. Sobre la cavidad del eje hueco se introduce un muelle, que presiona sobre la carcasa y le hace situarse en la posición más baja que le permite la carrera un pitón roscado sobre el eje hueco.When it comes to furniture with folding doors, the assembly is done in pairs, where they are articulated in their center by hinges while, at one end, the accessories described above are placed on the hinged door, and at the opposite end of the door. another door, is coupled vertically to the housing, a hollow shaft, introduced on one of the housings that has the housing itself. A spring is inserted over the cavity of the hollow shaft, which presses on the housing and causes it to be placed in the lowest position that allows the stroke a threaded pin on the hollow shaft.

Las bisagras comprenden una pluralidad de nervios que fortalecen el conjunto y evitan roturas por los repetitivos movimientos de los marcos, ya sea de abatimiento o de plegado.The hinges comprise a plurality of ribs that strengthen the assembly and avoid breakage by the repetitive movements of the frames, either folding or folding.

DESCRIPCIÓN DETALLADA DE LOS DIBUJOS DE LA INVENCIÓN DETAILED DESCRIPTION OF THE DRAWINGS OF THE INVENTION

En las Figuras 1 a 5 se representa una realización preferente de la invención, donde puede verse que una puerta comprende una pluralidad de marcos (M), donde cada marco comprende dos largueros verticales (1) iguales, de perfiles extrusionados, metálicos o plásticos, que se unen para la formación del marco con otros dos travesaños horizontales (2), idénticamente iguales respectivamente. Dicha unión se lleva a cabo mediante unas carcasas (3) iguales, constituidas de material metálico o plástico, las cuales van posicionadas en las cuatro esquinas mediante unas reglillas (30) , disponibles sobre su base y que encajan en el interior del travesaño (2) en una hendidura (20); por otra parte también se unen por medio de unas reglillas laterales (31) se ajustan en una hendidura (11) de los largueros (1), es decir, se une todo ello mediante un machihembrado en forma de cola de milano, en la que las figuras salientes están en la carcasa (3), mientras que sobre los perfiles (1 y 2) están las figuras entrante. Además, perfiles o travesaños horizontales (2), disponen de una terminación en doblez (21) en toda su longitud que encaja con una hendidura (32) que está en la carcasa (3). Finalmente, la construcción del marco (M) propiamente queda retenida y fijada de una forma segura con unos tornillos fijación (4) con arandela incorporada y que son roscados sobre la carcasa, presionando los perfiles en la construcción del conjunto marco.In Figures 1 to 5 a preferred embodiment of the invention is shown, where it can be seen that a door comprises a plurality of frames (M), where each frame comprises two equal vertical stringers (1), extruded profiles, metal or plastic, that join for the formation of the frame with two other horizontal crosspieces (2), identical identical respectively. Said connection is carried out by means of identical housings (3), made of metallic or plastic material, which are positioned at the four corners by means of slides (30), available on their base and which fit inside the crosspiece (2). ) in a slit (20); on the other hand, they are also joined by means of lateral struts (31) fit into a slot (11) of the longitudinal members (1), that is to say, all this is joined by means of a tongue and groove in the form of a dovetail, in which the protruding figures are in the housing (3), while on the profiles (1 and 2) are the incoming figures. In addition, profiles or horizontal crosspieces (2), have a fold over (21) along its entire length that fits with a slot (32) that is in the housing (3). Finally, the construction of the frame (M) itself is retained and fixed in a secure manner with fixing screws (4) with built-in washer and which are threaded on the housing, pressing the profiles in the construction of the frame assembly.

Para la formación de puertas plegables son necesarios al menos dos marcos (M), para lo cual dos largueros (1) contiguos relativos a dos marcos quedan fijados mediante unas bisagras (5) que quedan en ambos largueros, que comprenden una pluralidad de nervios (51) de refuerzo que refuerzan dicha bisagra y evitan la rotura de la misma tras su uso continuado. Esto se puede ver en detalle en la Figura 2.For the formation of folding doors, at least two frames (M) are necessary, for which two adjacent stringers (1) relative to two frames are fixed by means of hinges (5) that remain in both stringers, which comprise a plurality of ribs ( 51) that reinforce said hinge and prevent its rupture after continued use. This can be seen in detail in Figure 2.

Por otra parte, la carcasa (3), común para todas las esquinas, y fabricada de una sola pieza metálica o plástica, además de servir de escuadra de unión con los perfiles, dispone en su estructura de unos alojamientos interiores (33 y 34) en los que se ajustan los diferentes elementos accesorios que definen el uso del marco bien sea plegable o como marco abatible.On the other hand, the housing (3), common to all corners, and made of a single piece of metal or plastic, in addition to serving as a square to join the profiles, has in its structure some inner housings (33 and 34) in which the different accessory elements that define the use of the frame, either folding or as a folding frame, are adjusted.

En este sentido, las carcasas (3) incorporan en un alojamiento (34), preferentemente centrado, un eje de pivotamiento (6) que es regulable, que tiene su soporte giratorio sobre un casquillo roce de giro (62) insertado sobre una pieza soporte (61) que a su vez queda sujeta por un tornillo (63) en una hendidura longitudinal (100) ubicada en la base del perfil de rodadura superior e inferior (10) del marco. Este eje de pivotamiento (6) dispone de una parte roscada y de unos planos (64) que le impide girar sobre la carcasa por la sujeción que le realiza un tornillo de fijación (41), así mismo el eje pivotamiento (6) situado en la parte inferior intercala la arandela de roce (65) entre este eje (6) y el casquillo (62), y por otra parte una tuerca (66), la cual gradúa en su roscado el eje, permitiendo su giro manual y hace posicionar su altura a la medida ideal de funcionamiento. Una vez posicionado, queda bloqueado mediante el tornillo de fijación (41). El eje de pivotamiento (6) regulable se diseña con una longitud tal que evita que llegue a rozar la puerta en los perfiles de rodadura (10) de la guía inferior. Estos elementos se observan en detalle en la Figura 4.In this sense, the housings (3) incorporate in a housing (34), preferably centered, a pivot shaft (6) that is adjustable, having its support rotatable on a spinning bushing (62) inserted on a support piece (61) which in turn is held by a screw (63) in a longitudinal groove (100) located at the base of the upper and lower running profile (10) of the frame. This pivot axis (6) has a threaded part and planes (64) that prevents it from turning on the housing by the fastening provided by a fixing screw (41), likewise the pivoting axis (6) located in the lower part intercalary the friction washer (65) between this shaft (6) and the bushing (62), and on the other hand a nut (66), which graduates the shaft on its threading, allowing its manual rotation and makes it position its height at the ideal measure of operation. Once positioned, it is locked by the fixing screw (41). The adjustable pivot shaft (6) is designed with a length such that it prevents the door from rubbing against the rolling profiles (10) of the lower guide. These elements are observed in detail in Figure 4.

Este montaje pivotante es indistinto para todas las puertas abatibles y también para uno de los marcos extremos del juego de las puertas plegables articuladas. Los marcos de las puertas plegadas están conexionados o unidos entre sí por medio de unas bisagras (5), las cuales están fijadas en los propios largueros (1).This pivoting assembly is indistinct for all swing doors and also for one of the end frames of the articulated folding door set. The frames of the folded doors are connected or joined together by means of hinges (5), which are fixed on the stringers (1) themselves.

El montaje de los otros extremos, superior e inferior, se realiza mediante el posicionado de un pitón de deslizamiento (7) hueco, sobre uno de los alojamientos (33) extremos que dispone la carcasa (3), entre los que se interpone un muelle (71), ajustado en el interior del pitón de deslizamiento (7) hueco, que le proporciona una ligera presión hacia el exterior, y está regulado por una ranura (35) disponible en la propia carcasa (3), sobre la que discurre un eje deslizante (72) que, roscado sobre el pitón (7), impide su expulsión e impide que gire sobre sí mismo, siendo este eje el que se ajusta sobre un casquillo deslizante (73) que corre por la hendidura longitudinal (100) ubicada en las guías de los raíles superior e inferior (10) del marco. Estos elementos se observan en detalle en la Figura 5.The assembly of the other ends, upper and lower, is carried out by positioning a hollow sliding pin (7) on one of the end housings (33) provided by the housing (3), between which a spring is interposed. (71), fitted inside the hollow sliding pin (7), which provides a slight pressure to the outside, and is regulated by a groove (35) available in the housing (3), on which runs a sliding shaft (72) which, threaded on the pin (7), prevents its expulsion and prevents it from turning on itself, this axis being the one that fits on a sliding bushing (73) that runs through the longitudinal groove (100) located in the guides of the upper and lower rails (10) of the frame. These elements are observed in detail in Figure 5.

Finalmente, para completar la preparación de estos conjuntos marcos se ensamblan unas hojas o paños (8), formando el conjunto puerta, para lo cual los travesaños (2) y largueros (1) de los marcos (M) disponen de unos canales (9) en forma de U propios en sus perfiles presentados sobre el perímetro interior, sobre los que se alojan los tableros u hojas de las puertas propiamente, con lo cual mantienen la posibilidad de presentar una fabricación con los materiales y elementos decorativos deseados, fáciles de montar y/o intercalar. Por tanto, se consigue un conjunto optimizado donde se ha introducido unos elementos más robustos y resistentes que protegen al conjunto de posibles roturas en el abatimiento y plegado; y además se reducen los rozamientos con las guías. Finally, to complete the preparation of these frames assemblies leaves or cloths (8), forming the door assembly, for which the crosspieces (2) and stringers (1) of the frames (M) have channels (9) ) in the form of U own in their profiles presented on the interior perimeter, on which the boards or sheets of the doors themselves are housed, thereby maintaining the possibility of presenting a manufacturing with the desired materials and decorative elements, easy to assemble and / or intercalate. Therefore, an optimized assembly is achieved where more robust and resistant elements have been introduced that protect the set of possible breakages in folding and folding; and in addition the frictions with the guides are reduced.
