Definitions

  • the present invention relates to the field of shading structures used to obtain an adequate covering and protection from the sun and from the rain.
  • the model relates to a mechanism for actuating adjustable covering louvers used in shading structures, which may be folded, when needed, by means of a pantograph mechanism.

Abstract

L'invention concerne un mécanisme de pliage et rotation de volets réglables apte à protéger une zone en dessous, qu'ils recouvrent, des rayons du soleil, de la pluie ou d'autres agents atmosphériques. Le dispositif comprend une pluralité de volets destinés à la couverture d'une zone se trouvant en dessous, lesquels volets sont amenés en prise par une pluralité de tiges (3), qui sont contraintes successivement de façon à former une paire de mécanismes à pantographe (8), ceux-ci étant contraints aux barres de section de guidage (1) au moyen de chariots (6). Le dispositif est caractérisé en ce que les barres de section de guidage comprennent une rainure longitudinale partiellement ouverte (1b) profilée de façon à contenir une vis à développante (2), dont l'axe est parallèle à la direction longitudinale de développement de ladite barre de section de guidage (1) et une rainure longitudinale (1a) apte à retenir et à autoriser le coulissement desdits chariots (6). Le dispositif est caractérisé en outre en ce que les extrémités (4a, 4b) desdits volets sont contraintes à une extrémité d'une broche (4), qui contraint une paire de tiges (3) au niveau de la ligne médiane (3c), et comporte une roue dentée (5), qui est adaptée pour s'engrener avec la vis à développante (2) lorsque ledit pantographe (8) se trouve dans la configuration complètement étendue déterminant ainsi la rotation des volets.
