Description
DESCRIPCIONDESCRIPTION
Verja de seguridad retractil.Retractable security fence.
5 [0001] La presente invencion se refiere a una verja de seguridad retractil dotada de un sistema de arrollamiento y plegado de barras, que permite una reduccion dimensional de la carcasa necesaria para alojar la verja cuando esta completamente levantada.[0001] The present invention relates to a retractable security fence equipped with a bar winding and folding system, which allows a dimensional reduction of the housing necessary to house the fence when it is fully raised.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
1010
[0002] En el estado de la tecnica, existen diversas realizaciones de verjas de seguridad retractiles a emplearse en ventanas, puertas francesas y puertas principales, constituidas por una serie de barras restringidas entre si y conectadas a sistemas de elevacion que permiten que las barras se dispongan dentro de una carcasa cuando la verja esta completamente levantada.[0002] In the state of the art, there are various embodiments of retractable security gates to be used in windows, French doors and main doors, consisting of a series of bars restricted to each other and connected to lifting systems that allow the bars to be arrange inside a housing when the gate is completely raised.

[0003] Un ejemplo de dichos sistemas se describe en la Patente US2032461, en la que se describe una verja de seguridad retractil que comprende una serie de barras restringidas entre si por medio de una cadena, configurada de manera que puedan levantarse por medio de una rueda perfilada y empaquetarse "plegadas" sobre unas guias dispuestas en horizontal o en vertical. En el estado de la tecnica se conocen muchos otros ejemplos, como la[0003] An example of such systems is described in US2032461, in which a retractable security fence is described comprising a series of bars restricted to each other by means of a chain, configured so that they can be lifted by means of a profiled wheel and packaged "folded" on guides arranged horizontally or vertically. Many other examples are known in the state of the art, such as
20 solicitud italiana BA2009U000052 o las patentes italianas n.° 1327560, n.° 1388391 y n.° 1394469.20 Italian application BA2009U000052 or Italian patents No. 1327560, No. 1388391 and No. 1394469.
[0004] Otro ejemplo de dicho sistema es la solicitud de patente italiana BA2009A000034, presentada por los inventores de la presente solicitud de patente, en la que se describio una verja de seguridad retractil que comprendia una serie de barras paralelas transversales entre si articuladas por medio de un placas pequenas rectangulares, que[0004] Another example of such a system is the Italian patent application BA2009A000034, filed by the inventors of the present patent application, in which a retractable security fence was described which comprised a series of parallel cross bars articulated by means of each other. of a small rectangular plates, which
25 comprendian un sistema de arrollamiento para dichas barras por medio de discos perfilados.25 comprised a winding system for said bars by means of profiled discs.
[0005] Otros documentos son la solicitud de patente internacional WO2012/120483 y la solicitud de patente de Estados Unidos US4013113.[0005] Other documents are the international patent application WO2012 / 120483 and the US patent application US4013113.
30 [0006] Todos los documentos citados y muchos otros conocidos en el estado de la tecnica describen sistemas de plegado para las barras de verjas de seguridad retractiles.[0006] All the cited documents and many others known in the state of the art describe folding systems for the bars of retractable security bars.
[0007] Sin embargo, ninguno de los documentos conocidos en el estado de la tecnica describe sistemas de arrollamiento para las barras de verjas de seguridad retractiles que permitan optimizar la estructura sencilla y, sobre[0007] However, none of the documents known in the state of the art describe winding systems for the bars of retractable security bars that allow to optimize the simple structure and, on
35 todo, optimizar el espacio ocupado por las barras cuando estas estan completamente plegadas. Este ultimo aspecto es particularmente importante ya que cuando la verja esta completamente elevada, las barras plegadas estan contenidas en el interior de una carcasa colocada en las paredes exteriores del edificio. En muchos casos, la carcasa debe contener tambien una compuerta enrollable. Ademas, al espacio ocupado por las barras plegadas, en muchos casos se le anade el espacio ocupado por una capa termoaislante adecuada, destinada a corregir el puente 40 termico proporcionado por la carcasa.35 everything, optimize the space occupied by the bars when they are completely folded. This last aspect is particularly important since when the fence is completely raised, the folded bars are contained inside a housing placed on the exterior walls of the building. In many cases, the housing must also contain a roller gate. In addition, to the space occupied by the folded bars, in many cases the space occupied by a suitable heat-insulating layer is added, intended to correct the thermal bridge 40 provided by the housing.
[0008] Tambien hay que resaltar que las verjas de seguridad retractiles se instalan en caso de renovacion de edificios ya existentes. En estos casos, el espesor maximo de la carcasa se limita a la estructura existente del edificio, y una carcasa muy grande podria causar la imposibilidad tecnica de instalar la verja de seguridad retractil.[0008] It should also be noted that retractable security gates are installed in case of renovation of existing buildings. In these cases, the maximum thickness of the housing is limited to the existing structure of the building, and a very large housing could cause the technical impossibility of installing the retractable security fence.
45Four. Five
[0009] Por lo tanto, resulta evidente que en todas las situaciones mencionadas es necesario un sistema de plegado para las verjas de seguridad retractiles que permita reducir al minimo el espacio ocupado por las barras cuando estas estan plegadas dentro de la carcasa.[0009] Therefore, it is evident that in all the mentioned situations a folding system is necessary for the retractable safety gates that allow to minimize the space occupied by the bars when they are folded inside the housing.
50 [0010] Por lo tanto, el objetivo de la presente invencion es proporcionar una verja de seguridad retractil dotada de un sistema de guias instalado en la carcasa y con un sistema de elevacion que permita reducir al minimo el espacio ocupado por las barras en su conjunto. Debe precisarse que se utilizaran indistintamente las palabras verja de seguridad o verja.[0010] Therefore, the objective of the present invention is to provide a retractable security gate equipped with a guide system installed in the housing and with a lifting system that minimizes the space occupied by the bars in its set. It should be specified that the words security fence or fence be used interchangeably.
55 [0011] El objeto de la presente invencion consigue los objetivos prefijados puesto que es una verja de seguridad retractil dotada de un sistema de arrollamiento y plegado de barras que permite optimizar las dimensiones de la carcasa necesaria para alojar las barras de verja cuando la misma esta levantada completamente. Convenientemente, el sistema de arrollamiento de la verja objeto de la presente invencion permite plegar las barras aprovechando tambien la dimension horizontal de la carcasa ademas del espacio disponible en direccion vertical.[0011] The object of the present invention achieves the predetermined objectives since it is a retractable security fence equipped with a bar winding and folding system that allows optimizing the dimensions of the carcass necessary to accommodate the gate bars when it It is fully raised. Conveniently, the winding system of the fence object of the present invention allows the bars to be folded, also taking advantage of the horizontal dimension of the housing in addition to the space available in the vertical direction.
Por lo tanto, resulta evidente que es posible plegar el mismo numero de barras de igual espesor en una carcasa de menor dimension con respecto a lo necesario en los dispositivos conocidos en el estado de la tecnica o, como alternativa, es posible plegar un mayor numero de barras (que permiten proporcionar verjas para una carcasa de mayor altura) en carcasas de dimensiones equivalentes.Therefore, it is evident that it is possible to fold the same number of bars of equal thickness in a housing of smaller size with respect to what is necessary in the devices known in the state of the art or, alternatively, it is possible to fold a larger number of bars (which allow to provide railings for a carcass of greater height) in housings of equivalent dimensions.

20twenty
[0013] Con referencia a la figura 1, una realizacion preferida de la verja, objeto de la invencion, comprende una pluralidad de barras (1), cada una solidaria a una pequena placa respectiva (21). Las barras estan limitadas con respecto una a la otra por medio de bielas (22). Cada biela esta, de hecho, articulada a dos pequenas placas (21) correspondientes a un par de barras consecutivas (1).[0013] With reference to Figure 1, a preferred embodiment of the fence, object of the invention, comprises a plurality of bars (1), each integral with a respective small plate (21). The bars are limited with respect to each other by means of connecting rods (22). Each connecting rod is, in fact, articulated to two small plates (21) corresponding to a pair of consecutive bars (1).
2525
[0014] Las restricciones entre las barras y las pequenas placas pueden realizarse de acuerdo con modos conocidos en el estado de la tecnica, todos comprendidos en los objetivos de la presente invencion.[0014] The restrictions between the bars and the small plates can be carried out in accordance with ways known in the state of the art, all included in the objectives of the present invention.
[0015] De acuerdo con una realizacion preferida, pueden usarse arandelas (23) en teflon u otro material 30 autolubricante interpuestas en los acoplamientos entre las pequenas placas y las bielas, de manera que se evite la[0015] According to a preferred embodiment, washers (23) can be used in teflon or other self-lubricating material 30 interposed in the couplings between the small plates and the connecting rods, so as to avoid
necesidad de usar lubricantes.Need to use lubricants.
[0016] Ademas, los pasadores utilizados para restringir las pequenas placas y las bielas son alternativamente de diferente espesor (51, 52) de manera que sobresalgan hacia fuera a diferentes profundidades, como se muestra en[0016] In addition, the pins used to restrict small plates and connecting rods are alternately of different thickness (51, 52) so that they protrude outward at different depths, as shown in
35 la figura 8, donde la carcasa y las guias no se muestran para mayor claridad.35 Figure 8, where the housing and guides are not shown for clarity.
[0017] La verja de seguridad comprende tambien guias verticales (no mostradas en los dibujos) del tipo conocido en el estado de la tecnica, dentro de las cuales las pequenas placas (21) y las bielas (22) se deslizan cuando la verja esta bajada o levantada.[0017] The safety gate also includes vertical guides (not shown in the drawings) of the type known in the state of the art, within which the small plates (21) and the connecting rods (22) slide when the gate is lowered or raised
4040
[0018] El levantamiento y el descenso de las barras (1) se controlan por una rueda perfilada (3) y por un par de guias (41, 42). Como se muestra en la figura 4, la rueda perfilada (3) esta configurada de manera que se proporcione de forma periferica con una serie de ranuras (31, 32, 33) de tal forma que pueden albergar las barras (1). Las ranuras estan a una distancia adecuada la una con respecto a la otra, de manera que pueden engranarse,[0018] The lifting and lowering of the bars (1) are controlled by a profiled wheel (3) and by a pair of guides (41, 42). As shown in Figure 4, the profiled wheel (3) is configured so that it is peripherally provided with a series of grooves (31, 32, 33) so that the bars (1) can be accommodated. The grooves are at a suitable distance from each other, so that they can be engaged,
45 girando, siguiendo las barras de la verja.45 turning, following the bars of the gate.
[0019] El numero y la forma de las ranuras mostradas en la figura 4 han de ser un ejemplo de una realizacion preferida de la invencion y no limitar el objetivo de la misma. Pueden usarse ruedas con tres, cuatro o mas ranuras sin apartarse de los objetivos de la presente invencion. La rueda (3) esta restringida por la pared lateral de la[0019] The number and shape of the grooves shown in Figure 4 should be an example of a preferred embodiment of the invention and not limit the purpose thereof. Wheels with three, four or more grooves may be used without departing from the objectives of the present invention. The wheel (3) is restricted by the side wall of the
50 carcasa (5) de manera que pueda girar. Sobre el eje de rotacion de la rueda se puede instalar convenientemente un motor electrico (no mostrado en la figura) para el accionamiento de la verja. Incluso si en las figuras se muestra, para mayor simplicidad, solo un lado de la verja, resulta evidente que puede disponerse una rueda similar en el extremo opuesto de la carcasa, preferentemente enclavada en el mismo eje de rotacion y desplazada por medio del mismo motor electrico. Como se muestra en las figuras 4 y 7, las dos guias (41, 42) definen una trayectoria obligada para 55 las barras y las bielas. La forma de las dos guias es tal que estas definen una primera porcion de trayectoria sustancialmente vertical, instaladas en continuidad con las guias verticales (no mostradas) en las que las pequenas placas y las bielas se deslizan cuando se desciende la verja, y una segunda porcion que define una porcion de trayectoria sustancialmente circular. Esta porcion tendra una anchura mayor que la anchura definida por la porcion vertical de manera que sea posible el paso correcto de las pequenas placas y las bielas. El sistema esta configurado50 housing (5) so that it can rotate. An electric motor (not shown in the figure) for driving the gate can conveniently be installed on the axis of rotation of the wheel. Even if the figures show, for simplicity, only one side of the fence, it is evident that a similar wheel can be arranged at the opposite end of the housing, preferably locked in the same axis of rotation and displaced by means of the same motor electric. As shown in Figures 4 and 7, the two guides (41, 42) define a mandatory path for the rods and rods. The shape of the two guides is such that they define a first portion of substantially vertical trajectory, installed in continuity with the vertical guides (not shown) in which the small plates and the connecting rods slide when the gate is lowered, and a second portion that defines a substantially circular path portion. This portion will have a width greater than the width defined by the vertical portion so that the correct passage of the small plates and the connecting rods is possible. The system is configured
de modo que la rueda (3), en cuya ranura (31) se engrana una barra (1), obligue, girando, a dicha barra a seguir la seccion de trayectoria definida por las gufas (41,42) y engrana la barra siguiente con la siguiente ranura (32).so that the wheel (3), in whose groove (31) a bar (1) is engaged, forces, turning, to said bar to follow the path section defined by the guides (41,42) and gears the next bar with the following slot (32).
[0020] Convenientemente, la gufa exterior (42) termina casi en el extremo superior de la circunferencia definida por 5 la misma, de manera que se permita el movimiento de las pequenas placas y bielas mostradas en las figuras y que[0020] Conveniently, the outer guide (42) ends almost at the upper end of the circumference defined by it, so as to allow the movement of the small plates and connecting rods shown in the figures and that
se explica en detalle a continuacion.It is explained in detail below.
[0021] La gufa interna (41) comprende en cambio, despues de la seccion vertical (411), una segunda seccion horizontal (412) y una ultima seccion vertical (413), estando las tres secciones unidas con radios de curvatura[0021] The internal guide (41) comprises instead, after the vertical section (411), a second horizontal section (412) and a last vertical section (413), the three sections being joined with radii of curvature
10 adecuados.10 suitable.
[0022] El sistema comprende tambien una tercera gufa (43), dispuesta en diagonal y unida a la seccion vertical (413) casi en la conexion con la seccion horizontal, como se muestra en la figura 6.[0022] The system also comprises a third guide (43), arranged diagonally and connected to the vertical section (413) almost in connection with the horizontal section, as shown in Figure 6.
15 [0023] La vista lateral de la figura 6 permite observar que el espesor de la gufa (43), medido por la pared de la carcasa, es inferior al espesor de la gufa (41). De esta manera, la gufa inclinada (43) se engrana solamente por los pasadores (52) que sobresalen principalmente hacia fuera, permitiendo de esta manera un empaquetamiento plegado ordenado siguiendo una disposicion vertical, como se muestra en las imagenes. La presencia de la gufa inclinada es util, de hecho, para guiar el extremo de cada pequena placa que ha de situarse hacia fuera, evitando de 20 este modo el pegado del sistema.[0023] The side view of Figure 6 shows that the thickness of the guide (43), as measured by the wall of the housing, is less than the thickness of the guide (41). In this way, the inclined guide (43) is engaged only by the pins (52) that protrude mainly outward, thus allowing an orderly folded packing following a vertical arrangement, as shown in the images. The presence of the inclined guide is useful, in fact, to guide the end of each small plate to be placed outwardly, thus avoiding sticking of the system.
[0024] Ademas, ventajosamente la gufa interna esta dotada en la seccion horizontal (41) de un relieve (44) de menor espesor que el espesor de la gufa inclinada (43). De esta manera, el relieve no puede engranarse por los pasadores (51, 52) que limitan las pequenas placas adyacentes.[0024] In addition, the internal guide is advantageously provided in the horizontal section (41) of a relief (44) of a smaller thickness than the thickness of the inclined guide (43). In this way, the relief cannot be engaged by the pins (51, 52) that limit the small adjacent plates.
2525
[0025] Una unica placa pequena esta dotada de un pasador (53) de tales dimensiones que se engrana en el relieve (44). Esta pequena placa es la pequena placa que limita la primera barra (11) cuyas dimensiones excederan la altura vertical disponible para el plegado. Al engranar el relieve (44), el pasador (53) levanta el extremo de la barra. Ademas, convenientemente, la primera barra (11) que tiene que plegarse en posicion vertical, esta dotada de[0025] A single small plate is provided with a pin (53) of such dimensions that it engages in the relief (44). This small plate is the small plate that limits the first bar (11) whose dimensions will exceed the vertical height available for folding. When engaging the relief (44), the pin (53) lifts the end of the bar. Also, conveniently, the first bar (11) that has to be folded upright, is provided with
30 un relieve (12) dispuesto sobre la superficie que se plegara sobre la barra adyacente (14). El relieve (12) puede soldarse a la barra, atornillarse o constrenirse por otros medios adecuados, y tiene un espesor tal que se impide que la barra (11) se coloque en posicion horizontal. El angulo formado por la barra (11) con respecto a la horizontal cuando el relieve descansa sobre la barra anterior es tal que, cuando la rueda (3) esta levantando la verja, la fuerza ejercida por la biela restringida a la barra siguiente se dirige en la direccion de elevacion de la barra (11). Las 35 siguientes barras (15, 16) siguen plegandose en direccion horizontal, como se muestra en la figura.30 a relief (12) arranged on the surface to be folded over the adjacent bar (14). The relief (12) can be welded to the bar, screwed or constrested by other suitable means, and has a thickness such that the bar (11) is prevented from being placed horizontally. The angle formed by the bar (11) with respect to the horizontal when the relief rests on the front bar is such that, when the wheel (3) is raising the fence, the force exerted by the connecting rod restricted to the next bar is directed in the direction of elevation of the bar (11). The next 35 bars (15, 16) continue to fold in the horizontal direction, as shown in the figure.
[0026] De esta manera, ademas del espacio disponible en direccion vertical, es posible aprovechar la dimension horizontal de la carcasa para plegar las barras.[0026] In this way, in addition to the space available in the vertical direction, it is possible to take advantage of the horizontal dimension of the housing to fold the bars.
40 [0027] Por lo tanto, resulta evidente que es posible plegar el mismo numero de barras de igual espesor en una carcasa de dimensiones mas pequenas con respecto a lo necesario en los dispositivos conocidos en el estado de la tecnica o, de la misma manera, es posible plegar un mayor numero de barras (que permiten realizar una verja para carcasas de mayor altura) en carcasas de dimensiones equivalentes.[0027] Therefore, it is evident that it is possible to fold the same number of bars of equal thickness in a housing of smaller dimensions with respect to what is necessary in the devices known in the state of the art or, in the same way , it is possible to fold a greater number of bars (which allow a fence to be made for higher-rise carcasses) in carcasses of equivalent dimensions.
