Abstract

L'invention concerne une tête d'articulation pour structure de support d'une table pliante comprenant une base d'appui (2 ) sur la paroi latérale et verticale de laquelle sont pratiqués des orifices (3 ) destinés à recevoir la tête d'articulation. L'invention est caractérisée en ce que l'autre surface latérale de la base présente une rainure de guidage (7 ) destinée à recevoir un bras formée de deux barrettes (6 ) parallèles qui s'étendent sur la base d'appui (2 ), la partie se prolongeant au-delà de la base d'appui étant perforée (8 ) de trous destinés à recevoir un bras. Le bras se trouvant sur l'extrémité de la structure de support de la tête d'articulation assure une meilleure fixation au plateau de la table et un montage plus aisé. De plus, ledit bras, qui vient entre les têtes d'articulation, a pour avantage de renforcer la stabilité de la structure de support.
