Patent

CA 2200694

The invention concerns a lifting folding door (3), containing: two primarily vertically extending rails (4), arranged each on one side of the opening (2) to be closed by the door (3); a number of panels (8) hinged together, each of them guided by both rails; guiding means (6) connected at the top of each of the rails for guiding the panels such that, when moving upward, they are folded together in zigzag fashion by means of their hinge connections (12, 13) in primarily horizontal direction above the rails; operating means for driving at least one of the panels in vertical direction, in which the guiding means are designed for gradually deflecting the panels in horizontal direction, starting from the vertical movement. As a result of these steps, a purely vertical movement is gradually converted into a movement of a horizontal component, so that the dynamic forces acting on the respective elements are less, and therefore the speed can be significantly increased.

Porte pliante relevable (3) comportant deux glissières (4) s'étendant principalement dans le sens vertical et se trouvant sur des côtés respectifs de l'ouverture (2) fermée par la porte (3); un certain nombre de panneaux articulés (8) dont chacun est guidé par les deux glissières; des éléments de guidage (6) montés à l'extrémité supérieure de chacune des glissières et destinés à guider les panneaux de sorte que, lorsqu'ils montent, ils se replient les uns sur les autres à la manière d'un accordéon au moyen de leurs charnières (12, 13), et ce dans un sens principalement horizontal sur les glissières; et un organe de commande entraînant le déplacement vertical d'au moins un des panneaux, les éléments de guidage étant conçus pour dévier progressivement les panneaux en déplacement vertical, et leur imprimer un déplacement dans le sens horizontal. Par conséquent, un déplacement purement vertical est progressivement transformé en un déplacement à composante horizontale, ce qui réduit les forces dynamiques subies par les éléments respectifs, et permet donc d'augmenter considérablement la vitesse.
