Description

Mesa plegable.Folding table.

Object of the invention

La presente invención se refiere a una mesa plegable, del tipo de las que presentan un tablero a base de dos mitades abisagradas, susceptibles de adoptar una disposición coplanaria, concretamente en posición de trabajo de la mesa, o de abatirse una sobre otra con interposición de la estructura que las soporta, determinando a su vez una ocupación volumétrica mínima en situación inoperante de la mesa.The present invention relates to a table folding, of the type that have a board based on two hinged halves, likely to adopt a provision co-planarian, specifically in working position of the table, or of fold one over another with interposition of the structure that supports, in turn determining a minimum volumetric occupation in inoperative situation of the table.

El objeto de la invención es conseguir que la mesa resulte estructuralmente sólida, especialmente en posición de trabajo, y que además sus dimensiones en situación inoperante sean mínimas, con una gran facilidad de maniobra para pasar de una a otra posición.The object of the invention is to achieve that the table is structurally sound, especially in the position of work, and also that its dimensions in an inoperative situation are minimum, with a great ease of maneuver to move from one to other position

Background of the invention

Son conocidas mesas plegables cuyo tablero está fragmentado en dos mitades, unidas abisagradamente entre sí, estableciéndose bajo dicho tablero una estructura soporte, en la que participan las patas de la mesa, también plegable, de manera que dicha estructura se adapta a la cara inferior de las dos mitades del tablero, y es susceptible de plegarse conjuntamente con éste último para definir un cuerpo sensiblemente prismático-rectangular, similar al de una maleta, con su correspondiente asa, lo que facilita tanto el transporte como el almacenaje de la mesa.Folding tables are known whose board is fragmented into two halves, hingedly joined together, a support structure being established under said board, in the involved table legs, also foldable, so that said structure adapts to the underside of the two board halves, and is likely to fold together with the latter to define a body noticeably prismatic-rectangular, similar to that of a suitcase, with its corresponding handle, which facilitates both transport and Table storage

Dentro de las múltiples soluciones estructurales existentes para éste tipo de mesas, pueden establecerse dos grandes grupos, uno en el que realmente se consigue que la mesa en situación de plegado tenga unas dimensiones mínimas y que la estructura soporte del tablero quede totalmente oculta, lo que se consigue a expensas de una escasa estabilidad posicional de la mesa en situación de uso, y otro grupo en el que se consigue la citada solidez estructural de la mesa en su posición de uso, pero ello a expensas de una volumetría considerablemente mayor para la mesa, en situación de plegado, lo que repercute negativamente en su almacenaje y transporte.Within the multiple structural solutions existing for this type of tables, two large ones can be established groups, one in which you really get that table in folding situation has minimum dimensions and that the board support structure is completely hidden, which is at the expense of poor positional stability of the table in use situation, and another group in which the aforementioned is achieved structural strength of the table in its position of use, but this to at the expense of a considerably higher volumetry for the table, in folding situation, which negatively impacts your storage and transportation

Description of the invention

La mesa plegable que la invención propone combina las prestaciones de los dos tipos de mesa anteriormente citados, de manera que con una estructura que asegura una perfecta estabilidad posicional para la mesa, permite que dicha mesa ofrezca unas dimensiones mínimas en situación inoperante o de plegado, merced a la especial concepción de la estructura soporte de su tablero.The folding table that the invention proposes combines the benefits of the two types of table mentioned above, of so that with a structure that ensures perfect stability positional for the table, allows that table to offer some minimum dimensions in inoperative or folded situation, thanks to the special conception of the support structure of your board.

Para ello y de forma más concreta las dos porciones constitutivas del tablero, rectangulares e iguales entre sí, cuentan en su cara inferior con sendos rehundidos que las afectan mayoritariamente, y en los que encajan en situación de plegado la estructura soporte de dicho tablero.To do this and more specifically the two constituent portions of the board, rectangular and equal between yes, they have in their lower face with two recesses that mostly affect, and those who fit in a situation of folded the support structure of said board.

Dicha estructura se materializa para cada una de las dos porciones del tablero, en una pareja de largueros metálicos, convenientemente fijados a la porción correspondiente del tablero, en las zonas marginales del mismo, y de manera que la pareja de largueros correspondiente a una porción del tablero se une abisagradamente por su extremo interno a la pareja de largueros de la otra porción del tablero.This structure is materialized for each of the two portions of the board, in a pair of stringers metallic, conveniently fixed to the corresponding portion of the board, in the marginal areas of it, and so that the pair of stringers corresponding to a portion of the board is hingedly joins the pair of stringers at its inner end of the other portion of the board.

A cada pareja de largueros y cerca de su extremidad externa o libre, se une basculantemente un eje transversal, al que son solidarias una pareja de patas de la mesa, relacionadas entre sí mediante un travesaño, de manera que éstas patas son susceptibles de abatirse sobre la cara inferior de la porción correspondiente del tablero, sin sobresalir del rehundido de éste último, pudiendo adoptar una posición perpendicular a dicho tablero, correspondiente a la situación de uso de la mesa.To each pair of stringers and near their external or free limb, an axis is pivotally attached transversal, to which a pair of table legs stand in solidarity, related to each other by means of a crossbar, so that these legs are likely to fall on the underside of the corresponding portion of the board, not protruding from the recess of the latter, being able to adopt a position perpendicular to said board, corresponding to the situation of use of the table.

Para estabilizar las patas en situación de trabajo los citados largueros, en su otro extremo, es decir cerca de las bisagras que los relacionan, se une basculantemente una especie de horquilla triangular, que a través de su vértice se prolonga en un brazo a cuya extremidad libre se une articuladamente otra horquilla también triangular que relaciona dicho brazo con las patas, a nivel medio en altura de las mismas, de manera que estas dos horquillas con su brazo intermedio son susceptibles de disponerse en contraposición, estabilizando las patas en situación de trabajo o de situarse con sus lados paralelos, posición correspondiente al abatimiento de las patas sobre la cara inferior del tablero.To stabilize the legs in a situation of I work the mentioned stringers, at its other end, that is close of the hinges that link them, joins a kind of triangular fork, which through its vertex is prolongs in an arm whose free limb joins jointly another triangular fork that relates said arm to the legs, at medium level in height, so that these two forks with their intermediate arm are susceptible to set in contrast, stabilizing the legs in situation Working or standing with its parallel sides, position corresponding to the lowering of the legs on the lower face of the board.

Como complemento de la estructura descrita a uno de los largueros de la estructura, en su zona media, está unida basculantemente un asa, que cuando la mesa se encuentra en situación de cierre emerge al exterior entre las dos porciones del tablero resultando accesible para el transporte de la mesa como si se tratase de una maleta.As a complement to the structure described to one of the stringers of the structure, in its middle zone, is joined tiltingly a handle, which when the table is in closing situation emerges outside between the two portions of the board being accessible for table transportation as if It was a suitcase.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la mesa que se preconiza está constituida a partir de un tablero en el que participan dos porciones iguales (1-1'), tablero que puede ser de resina o de cualquier otro material apropiado, y en cada una de cuyas dos mitades (1-1') se establece un rehundido inferior (2) que la afecta mayoritariamente y que está destinado a alojar, en situación de plegado, a la estructura metálica soporte de dicho tablero, como se observa especialmente en la figura 3.In view of the figures outlined you can observe how the table that is recommended is made from of a board in which two equal portions participate (1-1 '), board that can be made of resin or any other appropriate material, and in each of whose two halves (1-1 ') a lower recess is established (2) that mostly affects it and that it is intended to accommodate, in a folded situation, to the metal support structure of said board, as seen especially in figure 3.

En el rehundido (2) de cada una de las porciones (1-1') del tablero, se establecen dos largueros laterales (3), que se fijan convenientemente a dicho tablero, por ejemplo por atornillamiento, estando los largueros (3) de la porción (1) relacionados con los largueros (3') de la segunda porción (1') a través de bisagras (4) que permiten el abatimiento de una porción del tablero sobre la otra, entre las posiciones límites representadas en las figuras 1 y 4.In the recess (2) of each of the portions (1-1 ') of the board, two stringers are established sides (3), which are conveniently fixed to said board, by example by screwing, the stringers (3) of the portion (1) related to the stringers (3 ') of the second portion (1 ') through hinges (4) that allow the folding of a portion of the board over the other, between the limit positions represented in figures 1 and 4.

Entre cada pareja de largueros (3-3') y cerca de su extremidad libre, se establece un eje transversal (5) al que son solidarias una pareja de patas (6), rigidizadas mediante un travesaño (7), patas (6) que pueden estar rematadas por su extremidad libre en tacos (8) de un material elastomérico o similar, para mejorar las condiciones de apoyo de la estructura sobre el suelo.Between each pair of stringers (3-3 ') and near its free limb, it is established a transverse axis (5) to which a pair of legs are in solidarity (6), stiffened by a crossbar (7), legs (6) that can be topped by its free end in studs (8) of a material elastomeric or similar, to improve the support conditions of the structure on the ground.

Las citadas patas (6) se estabilizan en la posición de trabajo mostrada en las figuras 1 y 2 con la colaboración de una especie de tirantes materializados en una primera horquilla (9), triangular, de extremos (10) acodados hacia fuera, a través de los que se une articuladamente a la extremidad de los largueros (3) próxima a las bisagras (4), siendo dicha horquilla (9) solidaria a través de su vértice externo a un brazo (11), preferentemente de longitud regulable, que a través de su extremidad libre se une articuladamente a una segunda horquilla (12), también triangular, cuyas dos ramas y por sus extremos divergentes se unen articuladamente a las propias patas (6) a un nivel medio en altura de las mismas, de manera que éstas horquillas son susceptibles de situarse en contraposición, separadas por el brazo (11), tal como muestra la figura 2, en situación operante de la mesa, o de adoptar una posición de paralelismo entre sus brazos divergentes, tal como muestra la figura 3, en situación de plegado para la mesa.The aforementioned legs (6) are stabilized in the working position shown in figures 1 and 2 with the collaboration of a kind of braces materialized in a first fork (9), triangular, with ends (10) angled towards outside, through which joins the limb articulately of the stringers (3) next to the hinges (4), said being fork (9) integral through its external vertex to one arm (11), preferably of adjustable length, which through its free limb joins articulated to a second fork (12), also triangular, whose two branches and its ends divergent jointly join the legs (6) to a medium level in height thereof, so that these forks are susceptible to stand in contrast, separated by the arm (11), as shown in figure 2, in an operating situation of the table, or adopting a parallel position between your arms divergent, as shown in figure 3, folded for the table.

Como complemento de la estructura descrita a la zona media de uno de los largueros (3) se une adecuadamente un asa (13), que en situación de uso de la mesa queda adaptada a la cara inferior del tablero (1), pero que en la maniobra de plegado de la mesa se abate emergiendo al exterior a través de ligeros rebajes (14) convenientemente establecidos en la zona marginal de las porciones (1-1') del tablero, lógicamente en situación de enfrentamiento a las ramas laterales de dicho asa (13), rebajes que resultan especialmente visibles en la figura 3.As a complement to the structure described in the middle zone of one of the stringers (3) a handle is properly attached (13), which in situation of use of the table is adapted to the face bottom of the board (1), but in the folding maneuver of the table is lowered emerging to the outside through slight recesses (14) conveniently established in the marginal zone of portions (1-1 ') of the board, logically in situation of confrontation with the lateral branches of said handle (13), recesses that are especially visible in the figure 3.

Se consigue de ésta manera una mesa perfectamente estable en la posición de trabajo para la misma mostrada en la figura 1, en la que la estructura sustentadora de su tablero es capaz de plegarse resultando prácticamente plana y encajando en los rehundidos (2) de la cara inferior del tablero (1-1'), de manera que en tal situación de plegado ambos sectores o porciones (1-1') del tablero contactan directamente entre sí a través de su cara inferior, constituyendo un cuerpo prismático-rectangular considerablemente aplanado, el mostrado en la figura 4, provisto de un asa (13) de transporte.A table is perfectly achieved in this way stable in the working position for the same shown in the Figure 1, in which the supporting structure of its board is able to fold resulting practically flat and fit in the recessed (2) of the underside of the board (1-1 '), so that in such a folding situation both sectors or portions (1-1 ') of the board contact each other directly through their lower face, constituting a prismatic-rectangular body considerably flattened, the one shown in figure 4, provided with a carrying handle (13).
