Generalmente, la reja incluye a lo largo de su perímetro una pluralidad de apoyos susceptibles de apoyarse sobre unos encajes complementarios pertenecientes al marco en la posición de uso.Generally, the fence includes along its perimeter a plurality of supports likely to rest on complementary lace belonging to the frame in the position of use

Actualmente, el procedimiento de fabricación del marco y la reja se lleva a cabo mediante fundición. Para ello, el marco y la reja se fabrican por separado, y una vez han sido desmoldeados son ensamblados.Currently, the manufacturing process of Frame and fence is carried out by casting. To do this, the frame and fence are manufactured separately, and once they have been Unmoulded are assembled.

En diseños complejos es necesario utilizar noyos en el interior del molde de arena que ayuden a obtener el diseño de las piezas.In complex designs it is necessary to use noyos inside the sand mold that help to obtain the design of The pieces.

El hecho de fabricar el marco y la reja por separado hace incrementar el tiempo de producción, así como los costes de fabricación al ser necesario tener dos moldes para obtener un dispositivo de cubrimiento.The fact of manufacturing the frame and the fence by separated increases production time, as well as manufacturing costs when it is necessary to have two molds to obtain a covering device.

b)b)
desmoldear el marco y la reja; yunmold the frame and the fence; Y

c)C)
girar la reja para montarla sobre el marco haciendo coincidir sus apoyos sobre los encajes complementarios del marco en la posición de uso.turn the fence to mount it on the frame by matching its supports on the complementary fittings of the frame in the position of use. 

       \vskip1.000000\baselineskip\ vskip1.000000 \ baselineskip

De este modo, es posible moldear el marco y la reja conjuntamente en un mismo molde, y sin necesidad de noyos, reduciéndose por tanto el tiempo y el coste de fabricación del dispositivo de cubrimiento.In this way, it is possible to mold the frame and the grating together in the same mold, and without the need for noyos, reducing therefore the time and manufacturing cost of the covering device

Preferentemente, la reja en la posición de moldeo está girada 180º según un eje perpendicular al plano que contiene la reja.Preferably, the fence in the position of molding is rotated 180º along an axis perpendicular to the plane that It contains the fence.

De acuerdo con otro aspecto de la invención, el dispositivo de cubrimiento, cierre y similares, obtenido mediante el procedimiento descrito anteriormente, se caracteriza por el hecho de que en la posición de moldeo, la reja está dispuesta dentro del marco con sus apoyos desplazados con respecto a los encajes complementarios del marco y en una posición girada con respecto a su posición de uso, mientras que en la posición de uso, la reja está montada sobre el marco con sus apoyos coincidentes sobre los encajes complementarios del marco.According to another aspect of the invention, the covering, closing and similar device, obtained by The procedure described above is characterized by the fact that in the molding position, the fence is arranged inside the frame with its supports displaced with respect to the lace complementary to the frame and in a rotated position with respect to its use position, while in the use position, the fence it is mounted on the frame with its matching supports on the Complementary frame lace.

Descripción de una realización preferidaDescription of a preferred embodiment

Haciendo referencia a las figuras, el dispositivo 1 de cubrimiento, cierre y similares, obtenible mediante el procedimiento de la presente invención, comprende un marco fijo 2 y una reja 3 montada interiormente a dicho marco 2, incluyendo dicha reja 3 a lo largo de su perímetro una pluralidad de apoyos 4 susceptibles de apoyarse sobre unos encajes complementarios 5 pertenecientes al marco 2 en la posición de uso.Referring to the figures, the covering device 1, closure and the like, obtainable by  The process of the present invention comprises a fixed frame 2 and a fence 3 mounted internally to said frame 2, including said grid 3 along its perimeter a plurality of supports 4 likely to rely on complementary lace 5 belonging to frame 2 in the position of use.

El procedimiento de obtención del dispositivo 1 de cubrimiento, cierre y similares, de la presente invención consiste en realizar las siguientes etapas:The procedure for obtaining the device 1 of covering, closing and the like of the present invention It consists of performing the following stages:

En primer lugar, se procede a obtener en un mismo molde mediante fundición el marco 2 y la reja 3. Para ello, en la posición de moldeo (véase figuras 1 a 3), la reja 3 queda formada dentro del marco 2 con sus apoyos 4 desplazados con respecto a los encajes complementarios 5 del marco 2, y en una posición girada 180º con respecto a su posición de uso, según un eje perpendicular al plano que contiene la reja 3.First, we proceed to obtain in a same mold by casting the frame 2 and the gate 3. To do this, in the molding position (see figures 1 to 3), gate 3 is left formed within frame 2 with its supports 4 displaced with with respect to the complementary fittings 5 of the framework 2, and in a position rotated 180º with respect to its use position, according to a axis perpendicular to the plane that contains grid 3.

De esta manera, en la posición de moldeo la reja 3 queda dispuesta dentro del marco 2 sin llegar a tocarse entre sí dentro de un único molde.In this way, in the molding position the fence 3 is arranged within frame 2 without touching each other within a single mold.

A continuación, se procede a desmoldear el marco 2 y la reja 3. Una vez desmoldeada la reja 3, ésta debe girarse, en este ejemplo 180º, para montarla sobre el marco 2 haciendo coincidir sus apoyos 4 sobre los encajes complementarios 5 del marco 2 en la posición de uso (véase figuras 4 a 6).Next, we proceed to unmold the frame 2 and gate 3. Once the gate 3 has been demoulded, it must be turned, in this 180º example, to mount it on frame 2 by matching its supports 4 on the complementary fittings 5 of the frame 2 in the position of use (see figures 4 to 6).

Cabe destacar que la reja puede diseñarse para ser girada cualquier valor de ángulo adecuado, preferentemente 90º o 180º, según un mismo plano, o incluso puede ser girada volteándola.It should be noted that the fence can be designed to any suitable angle value is rotated, preferably 90º or 180º, according to the same plane, or it can even be rotated flipping it
