Description
Porte de ventilation, à palettes. L'invention a pour objet une porte de ventilation, à palettes, dont le dessin ci-joint, montre, à titre d'exemple, une forme d'exé cution.
La fig. 1 est une vue de face, un cou vercle est supposé arraché en partie pour laisser voir le mécanisme, et les palettes sont dans la position fermée; Les fig. 2 et 3 sont des coupes verticales, correspondant à la fig. 1; Les fig. 4 et 5 se rapportent à la posi tion d'ouverture.
Les organes de tirage 1 et 2, des chaî nettes par exemple, sont destinés, le premier à mettre les palettes dans la position d'ou verture, le second à les ramener dans la position de fermeture, toutes les palettes étant reliées entre elles par une bielle 3 articulée sur des oreilles 4 solidaires chacune de l'une desdites palettes. Chacune de ces dernières, portée par un cadre 5, est suscep tible d'osciller autour d'un axe horizontal. Sur la palette placée au bas de la porte est fixée une pièce dont une partie 6 recour bée à angle droit est articulée à une biel- lette 7 articulée elle-même à un levier 8 porté par le cadre 5. A ce levier, pouvant osciller en 81, est attaché l'organe 1 de tirage.
Une autre pièce fixée à cette palette est recourbée à angle droit de façon à constituer un levier 9 auquel est attaché l'organe 2 de tirage.
Un couvercle 10 fixé au cadre 5, est évidé de façon quelconque pour laisser la surface d'ouverture nécessaire et les leviers 8 et 9 peuvent ainsi traverser le couvercle et osciller.
Ventilation door, with pallets. The invention relates to a ventilation door, with pallets, the accompanying drawing of which shows, by way of example, one embodiment.
Fig. 1 is a front view, a cover is supposed to be partially torn off to show the mechanism, and the paddles are in the closed position; Figs. 2 and 3 are vertical sections, corresponding to FIG. 1; Figs. 4 and 5 refer to the opening position.
The pulling members 1 and 2, net chains for example, are intended, the first to put the pallets in the opening position, the second to bring them back to the closed position, all the pallets being connected together by a connecting rod 3 articulated on lugs 4 each integral with one of said pallets. Each of these, carried by a frame 5, is capable of oscillating about a horizontal axis. On the pallet placed at the bottom of the door is fixed a part of which a part 6 curved at right angles is articulated to a link 7 itself articulated to a lever 8 carried by the frame 5. This lever can oscillate. at 81, is attached the pulling member 1.
Another part fixed to this pallet is bent at right angles so as to constitute a lever 9 to which the pulling member 2 is attached.
A cover 10 fixed to the frame 5 is recessed in any way to leave the necessary opening area and the levers 8 and 9 can thus pass through the cover and oscillate.
