(17) cilíndrico, que queda apoyado transversalmente sobre unos cajetines verticales extremos (18) de los largueros, con posibilidad de girar sobre sus apoyos, a modo de eje de giro de la pata, mientras que el otro perfil lateral (19) presenta una superficie plana provista de tacos extremos (20) de apoyo de la pata en el suelo, así como también se apoya en los largueros cuando se produce el plegado de la pata. (17) cylindrical, which is supported transversely on extreme vertical boxes (18) of the stringers, with the possibility of turning on its supports, as a pivot axis of the leg, while the other side profile (19) has a flat surface provided with end plugs (20) supporting the leg on the floor, as well as resting on the stringers when the leg is folded.

Estos perfiles laterales de la pata en "U" ladeada quedan unidos por el perfil intermedio (21 ) en forma de barra que determina la altura de la pata y sobre la que se articula la biela (16) de apertura y cierre de dicha pata. These lateral profiles of the side "U" leg are joined by the intermediate profile (21) in the form of a bar that determines the height of the leg and on which the connecting rod (16) of opening and closing said leg is articulated.

Igualmente en la figuras sexta y séptima se puede observar que los cajetines verticales extremos (18) de los largueros presentan la forma de un cuerpo prismático rectangular hueco, provisto de medios de anclaje (22) para su fijación a los largueros, así como de un orificio (23) que recibe un casquillo (24) que hace de alojamiento para la rotación libre del perfil lateral (17) cilíndrico o eje giratorio de la pata. Also in the sixth and seventh figures it can be seen that the extreme vertical boxes (18) of the stringers have the shape of a hollow rectangular prismatic body, provided with anchoring means (22) for fixing to the stringers, as well as a hole (23) that receives a bushing (24) that serves as a housing for the free rotation of the cylindrical lateral profile (17) or rotary axis of the leg.

Además cada cajetín está cerrado por su zona inferior por un taco reforzado (25) con cartelas, que está dotado en su base de medios antideslizantes (26) ,que queda situado por debajo de los ejes de giro de las patas en disposición de permitir el apilamiento de las mesas invertidas para ocupar menos espacio en su almacenamiento y/o transporte. In addition, each box is closed in its lower area by a reinforced block (25) with brackets, which is provided at its base with non-slip means (26), which is located below the pivot axes of the legs in order to allow stacking of inverted tables to occupy less space in storage and / or transport.

De esta manera, se permite el apoyo del tablero (1) de una mesa superior invertida, sobre los cuatro tacos reforzados (25) de los cajetines (18) de una mesa inferior invertida, que con los medios antideslizantes (26) previstos en la base de apoyo de los tacos se evita el deslizamiento entre las mesas apiladas. In this way, the support of the board (1) of an inverted upper table is allowed, on the four reinforced blocks (25) of the boxes (18) of an inverted lower table, than with the non-slip means (26) provided in the Taco support base prevents slippage between stacked tables.

En las figuras octava y novena se puede observar que la mesa ligera plegable es susceptible de incorporar un tablero frontal (27) a modo de faldón de cierre del hueco de la mesa, dotado en el borde superior de unos perfiles en L (28) a modo de asideros, mientras que por su cara interna presentan unos perfiles laterales en forma de omega (29) en disposición de quedar enganchados a unas pestañas angulares (30) conformadas en al menos los tacos reforzados (25) de los cajetines frontales de la mesa. In the eighth and ninth figures it can be seen that the folding light table is capable of incorporating a front panel (27) as a closing skirt of the table hollow, provided on the upper edge of L-shaped profiles (28) a handle mode, while on its inner side they have omega-shaped side profiles (29) in a position to be hooked to angular tabs (30) formed in at least the reinforced studs (25) of the table's front boxes .

Asimismo en las figuras octava y novena se puede observar que la mesa es susceptible de disponer montada sobre el tablero superior (1 ) una regleta de conexiones eléctricas (31 ), dotada en su frontis de al menos dos pletinas angulares Also in the eighth and ninth figures it can be seen that the table is capable of having mounted on the top board (1) a power strip (31), equipped with at least two angular plates on its front

(32) abiertas hacia el interior de la mesa, que están provistas en su tramo horizontal de unos tornillos de apriete (33), en disposición de acoplarse y fijarse al borde de la mesa . (32) open towards the inside of the table, which are provided in its horizontal section with some tightening screws (33), ready to be coupled and fixed to the edge of the table.
