Siguiendo los dibujos, el mecanismo extensible para mesa, de perímetro circular, objeto del presente modelo de utilidad, se caracteriza por estar constituido por las dos guías extensibles (1), situadas simétricamente con respecto al eje longitudinal de la mesa (2).Following the drawings, the extensible mechanism for table, of circular perimeter, object of the present model of utility, is characterized by being constituted by the two guides extensible (1), located symmetrically with respect to the axis longitudinal table (2).

Cada una de estas guías extensibles (1) está constituida por un perfil metálico exterior envolvente fijo (3), de sección poligonal hexagonal irregular, por cuyo interior se deslizan, en sentido opuesto, los dos tramos (4a) y (4b) de perfil, desplegables horizontalmente, de sección coincidente con el interior del perfil envolvente (3) de la guía extensible (1).Each of these extendable guides (1) is constituted by a fixed outer metal profile (3), of irregular hexagonal polygonal section, whose interior is slide, in the opposite direction, the two sections (4a) and (4b) in profile, horizontally deployable, with a section that coincides with the interior of the envelope profile (3) of the extensible guide (1).

La disposición de una cierta cantidad de esferas metálicas (11), entre las caras inclinadas coincidentes, superiores e inferiores, del perfil envolvente fijo (3) y los perfiles desplazables (4a) y (4b), transforman este conjunto en un elemento de rodamiento de bolas, con un deslizamiento suave y sin esfuerzo, de los tramos de perfil interior desplazables (4a) y (4b), por dentro del perfil exterior envolvente (3). Esta disposición la muestra claramente la figura 5, en una sección de la guía (1) y elementos contiguos.The arrangement of a certain amount of spheres metallic (11), between the coincident inclined faces, upper and lower, of the fixed envelope profile (3) and the profiles moveable (4a) and (4b), transform this set into an element Ball bearing, with smooth and effortless sliding, of the movable inner profile sections (4a) and (4b), by inside the outer envelope profile (3). This provision the clearly shows figure 5, in a section of the guide (1) and contiguous elements.

Así dispuestos los elementos básicos del mecanismo extensible que se describe, los tramos de perfil interior (4a) y (4b) de las guías (1) del mecanismo, están fijados, mediante los elementos adecuados, a la cara inferior de cada una de las dos porciones semicirculares, (2a) y (2b), del tablero de la mesa (2), de modo que cuando el usuario proceda a separar manualmente ambas porciones del tablero de la mesa (2), los mencionados tramos (4a) y (4b) de perfil interior, también se desplazarán conjuntamente, desplazamiento que efectuarán por el interior del perfil envolvente exterior (3), y acompañando a las mencionadas porciones (2a) y (2b) de tablero en este desplazamiento, tanto si es para separación, cuando se desee extender la mesa, como si es para unirlos, cuando se desee recoger dicha mesa.Thus arranged the basic elements of Extensible mechanism described, the inner profile sections (4a) and (4b) of the guides (1) of the mechanism, are fixed, by the appropriate elements, to the underside of each of the two semicircular portions, (2a) and (2b), of the board of the table (2), so that when the user proceeds to separate manually both portions of the tabletop (2), the mentioned sections (4a) and (4b) of internal profile, also will move together, displacement that will make by the inside the outer envelope profile (3), and accompanying the mentioned portions (2a) and (2b) of board in this displacement, whether for separation, when desired extend the table, as if to join them, when you want to pick up said table.

Por el contrario, el perfil envolvente exterior (3) permanecerá teóricamente posicionado, sin desplazarse, en la zona que puede denominarse "franca" F, de la de la mesa, es decir en la zona abierta y aún no cubierta por tablero alguno, resultante de la separación de las mencionadas porciones semicirculares (2a) y (2b) del tablero de la propia mesa (2). (Ver Figura 2).On the contrary, the outer envelope profile (3) remain theoretically positioned, without moving, in the area that can be called "frank" F, of that of the table, is say in the open area and not yet covered by any board, resulting from the separation of said portions semicircular (2a) and (2b) of the board of the table itself (2). (Watch Figure 2).

Los perfiles desplazables (4a) y (4b), de cada lado del mecanismo, quedan solidarizados entre sí, constituyendo un rectángulo de estabilidad del conjunto extensible, mediante los travesaños rectangulares (5a) y (5b), fijados sobre la cara interior de los mencionados perfiles envolventes (3), y justo en sus extremos, por unas placas (6).The movable profiles (4a) and (4b), of each side of the mechanism, they are in solidarity with each other, constituting a stability rectangle of the extensible assembly, by means of rectangular crossbars (5a) and (5b), fixed on the face inside of the aforementioned envelope profiles (3), and just in their ends, by plates (6).

En la zona delimitada por este rectángulo de estabilidad, quedarán posicionados los módulos desplegables de la mesa, constituido cada uno de ellos por los semimódulos (7a) y (7b), y (8a) y (8b), respectivamente.In the area delimited by this rectangle of stability, the drop-down modules of the table, each consisting of the semimodules (7a) and (7b), and (8a) and (8b), respectively.

Las dos porciones semicirculares (2a) y (2b) del tablero de la mesa (2) están solidarizados a su vez con los pies (9a) y (9b) de la propia mesa.The two semicircular portions (2a) and (2b) of the tabletop (2) are in turn in solidarity with their feet (9a) and (9b) of the table itself.

Estos pies, idénticos y de forma semicilíndrica, quedan situados juntos uno al otro, cuando la mesa está recogida o cerrada, constituyendo un único pie cilíndrico (9), gracias a su simetría. La zona de contacto de un pie con el otro es la cara plana vertical que cada uno posee en su parte interior.These feet, identical and semi-cylindrical, they are placed together to each other, when the table is collected or closed, constituting a single cylindrical foot (9), thanks to its symmetry. The contact area of one foot with the other is the face vertical plane that each one has inside.

En una realización práctica, estos pies semicilíndricos (9a) y (9b) podrán ubicarse sobre sendas peanas semicirculares de sustentación (10a) y (10b), a modo de embellecedor.In a practical embodiment, these feet semi-cylindrical (9a) and (9b) may be placed on footpaths lifting semicircular (10a) and (10b), by way of beautifying

Cuando la mesa se extiende, y también al recogerse, los pies semicilíndricos (9a) y (9b) se desplazarán juntamente con las porciones semicirculares (2a) y (2b) de tablero, garantizando el apoyo y estabilidad del conjunto en todo momento.When the table is extended, and also at collect, the semi-cylindrical feet (9a) and (9b) will move together with the semicircular portions (2a) and (2b) of board, guaranteeing the support and stability of the whole in all moment.

Cuando las mencionadas guías (1) están recogidas, y la totalidad de los perfiles interiores desplazables (4a) y (4b) están posicionados en el interior de los respectivos perfiles envolventes (3), la mesa (2) estará en la posición de cerrada o recogida, con sus dos posiciones semicirculares (2a) y (2b) unidas, formando un tablero uniforme, perfectamente circular.When the mentioned guides (1) are collected, and all movable interior profiles (4a) and (4b) are positioned inside the respective profiles envelopes (3), the table (2) will be in the closed position or collection, with its two semicircular positions (2a) and (2b) joined together, forming a uniform board, perfectly circular.

Un dispositivo adecuado permite que los semimódulos desplegables (7a,7b) y (8a,8b) queden recogidos y ocultos bajo el tablero cuando la mesa (2) está en su posición de recogida, y puedan desplegarse, mediante la acción manual adecuada, representada en la figura 6, cuando los perfiles desplazables (4a) (4b) del mecanismo extensible han sido extraídos, deslizándose suavemente gracias a la acción de rodamiento de bolas (11) del conjunto de las guías (1), por el interior de los correspondientes perfiles exteriores envolventes fijos (3).A suitable device allows the deployable semimodules (7a, 7b) and (8a, 8b) are collected and hidden under the board when the table (2) is in its position of collection, and can be deployed, by appropriate manual action, represented in figure 6, when the movable profiles (4a) (4b) of the extensible mechanism have been removed, sliding gently thanks to the ball bearing action (11) of the set of guides (1), inside the corresponding fixed outer wrap profiles (3).

Coadyuva al mencionado dispositivo un eje cilíndrico longitudinal (12), algo distanciado respecto al eje central longitudinal de la mesa. Este eje (12) va fijado a los travesaños rectangulares (5a) y (5b).Contribute to the mentioned device an axis longitudinal cylindrical (12), somewhat spaced from the axis longitudinal center of the table. This axis (12) is fixed to the rectangular crossbars (5a) and (5b).

Cada uno de los dos módulos desplegables, quedan posicionados, plegados por la mitad, gracias a que los correspondientes semimódulos (7a) y (7b), así como los semimódulos (8a) y (8b), están unidos por sendas bisagras tipo "tapa de piano" (13), quedando sujetos los semimódulos (7a) y (8a) al eje clíndrico (12) mediante unas abrazaderas (14), que permiten el giro y volteo de dichos semimódulos sobre el mencionado eje (12).Each of the two drop-down modules remains positioned, folded in half, thanks to the fact that corresponding semimodules (7a) and (7b), as well as semimodules (8a) and (8b), are joined by two hinges type "cover of piano "(13), the semimodules (7a) and (8a) being attached to the axis cylindrical (12) by means of clamps (14), which allow the rotation and turning said semimodules on said axis (12).

Cuando los semimódulos (7a) y (7b), (8a) y (8b) están plegados y ocultos bajo las porciones semicirculares (2a) y (2b), unidas, de la mesa (2), todos ellos quedan por debajo del eje de giro (12).When the semimodules (7a) and (7b), (8a) and (8b) they are folded and hidden under the semicircular portions (2a) and (2b), joined, of the table (2), all of them are below the axis turn (12).

Una vez la mesa se ha extendido y los módulos desplegables (7a, 7b) y (8a, 8b) quedan al descubierto, en la zona franca (F) de la mesa (2) se podrá proceder al desplegado manual de los mismos haciéndolos girar sobre dicho eje (12) para que queden posicionados por encima del referido eje (12), momento en que se procederá al desplegado total de los semimódulos, tal como representa la figura 6, quedando extendidos , perfectamente horizontales y lisos, al mismo nivel del tablero de la mesa (2). (Ver Figura 7).Once the table has been extended and the modules deployable (7a, 7b) and (8a, 8b) are exposed, in the area free (F) of the table (2) you can proceed to manual deployment of the same turning them on said axis (12) so that they are positioned above the aforementioned axis (12), when will proceed to the total deployment of the semimodules, such as represents figure 6, being extended, perfectly horizontal and smooth, at the same level as the tabletop (2). (See Figure 7).

Estos semimódulos, ya desplegados y posicionados, quedan perfectamente apoyados sobre los propios perfiles desplazables (4a) y (4b).These semimodules, already deployed and positioned, they are perfectly supported on the profiles themselves movable (4a) and (4b).

Las porciones semicirculares (2a) y (2b), separadas y entre ambas los semimódulos (7a) (7b) y (8a) (8b), totalmente desplegados, formarán una superficie plana y continua, sin reborde ni alteración alguna, apta para su utilización inmediata.The semicircular portions (2a) and (2b), separated and between both the half-modules (7a) (7b) and (8a) (8b), fully deployed, they will form a flat and continuous surface, without flange or alteration, suitable for use immediate.

En el caso de que se desee extender la mesa únicamente la amplitud correspondiente al primero de los semimódulos (7a) (7b), el usuario detendrá el desplazamiento de los perfiles interiores (4a) (4b), en el momento en que quede al descubierto la totalidad de dichos semimódulos (7a) y (7b), procediendo entonces al desplegado manual de dichos semimódulos, de forma idéntica a como se efectuará el desplegado de la totalidad de los semimódulos (7a) y (7b), (8a) y (8b), cuando se desee extender la mesa (2) en toda su longitud.In case you want to extend the table only the amplitude corresponding to the first of semimodules (7a) (7b), the user will stop the movement of the interior profiles (4a) (4b), at the time it is at discovered all said semimodules (7a) and (7b), then proceeding to the manual deployment of said semimodules, of identical to how the deployment of all of the semimodules (7a) and (7b), (8a) and (8b), when you want to extend the table (2) in its entire length.

Así pues, el desplazamiento de los perfiles interiores (4a) y (4b) de las guías (1), podrá llevarse a cabo de forma total o parcial, es decir, extrayendo la totalidad de estos perfiles interiores desplazables (4a) y (4b) o solamente la mitad de su longitud, con la finalidad de obtener un aumento doble de la longitud del tablero de la mesa (2) o bien un 50% de aumento de dicha longitud.So, shifting profiles interior (4a) and (4b) of the guides (1), may be carried out total or partial form, that is, extracting all of these internal movable profiles (4a) and (4b) or only half of its length, in order to obtain a double increase of the tabletop length (2) or a 50% increase in said length

En el primero de los casos, quedarán ambos desplegables (7a) (7b) y (8a) (8b) al descubierto, mientras que en el segundo caso quedará solamente al descubierto los semimódulos primeros (7a) y (7b).In the first case, both will remain deployable (7a) (7b) and (8a) (8b) exposed while in the second case will only reveal the semimodules first (7a) and (7b).
