Patent

CA 2168857

A slot ventilator (100, 500) comprises a slotted backing member (24, 124, 424, 524), an elongate facing strip (26, 126, 426, 526, 626), and a linkage mechanism connecting the backing member and facing strip with one another, the linkage mechanism being arranged to permit generally translational forward and backward movement of the facing strip between a closed position in which the slot is closed and an open position in which the facing strip is spaced in front of the backing member. The linkage mechanism includes a hinge (58, 158, 300) allowing the facing strip to rotate about a longitudinal axis to vary the angular orientation thereof. When installed horizontally in a window frame (14, 588, 588'), the facing strip may be moved forwards and backwards to increase and decrease ventilation, and may be rotated about the hinge to divide incoming ventilation favourably between downward and upward directions.

Un dispositif de ventilation (100, 500) à fente comprend un élément de support (24, 124, 424, 524) à fente, une bande extérieure allongée (26, 126, 426, 526, 626), ainsi qu'un mécanisme d'accouplement les reliant reciproquement et agencé de façon à permettre le déplacement de la bande extérieure vers l'avant et vers l'arrière entre une position fermée dans laquelle la fente est fermée, et une position ouverte dans laquelle la bande est espacée par rapport à l'élément de support. Le mécanisme d'accouplement comprend une charnière (58, 158, 300) permettant de tourner la bande extérieure autour d'un axe longitudinal afin d'en varier l'orientation angulaire. Lorsque la bande est placée horizontalement dans le cadre (14, 588, 588') d'une fenêtre, elle peut être déplacée vers l'avant et vers l'arrière afin d'augmenter ou de réduire le niveau de ventilation, et elle peut être tournée autour de la charnière afin d'orienter simultanément le courant d'air d'arrivée en deux directions, notamment vers le haut et vers le bas.
