Means for closing an opening in a wall consisting of a plastic cloth and a flexible air duct having the length of the opening perimeter and having a nipple inserted into one end with the second end being deadly closed. The opening is closed by a plastic cloth with its ends covering butt ends of the opening and an air duct being laid over the cloth along the whole perimeter of the opening, the said air duct being spread inside the opening after air pumping into it, and thus holding the cloth in its place like a frame.

La présente invention concerne un moyen permettant de refermer une ouverture ménagée dans une paroi, lequel moyen consiste en une étoffe en plastique et en un conduit d'air souple présentant une longueur correspondant au périmètre de l'ouverture et comprenant un mamelon inséré dans une extrémité, la seconde extrémité étant condamnée. L'ouverture est fermée par une étoffe en plastique dont les extrémités recouvrent les extrémités de butée de l'ouverture et un conduit d'air est placé par dessus l'étoffe le long de l'ensemble du périmètre de l'ouverture. Le conduit d'air est déployé à l'intérieur de l'ouverture après le pompage de l'air à l'intérieur de celui-ci, ce qui permet de maintenir l'étoffe à sa place comme un châssis.
