CA 2527282

A collapsible air vent closure is disclosed comprising a frame having a frame aperture. A closure is mounted to the frame for pivoting between a closed position and an open position. A movable vent wall having a vent orifice is interposed between the frame and the closure. The vent orifice provides an air flow path to the frame aperture when the closure is in the open position. The closure inhibits the air flow path to the frame aperture when the closure is in the closed position.

L'invention concerne une fermeture pliable pour évent qui comprend un cadre pourvu d'une ouverture de cadre. Une fermeture est montée sur le cadre de manière à pouvoir pivoter entre une position fermée et une position ouverte. Une paroi d'évent mobile possédant un orifice pour évent est disposée entre le cadre et la fermeture. L'orifice de l'évent permet de former une voie d'écoulement d'air jusqu'à l'ouverture de cadre lorsque la fermeture est en position ouverte. La fermeture ralentit l'écoulement de l'air jusqu'à l'ouverture de cadre lorsque la fermeture est en position fermée.
