Definitions

• the invention applies to the sealing of passages in which there is in particular a problem of size.
• the installation of a shutter curtain that is resistant, waterproof and fireproof is often impossible in cases, such as car ferry or parking lot, where any protrusion over the entire width of the ceiling or on the side walls reduces the passing vehicles template on the entire surface of use.
• the object of the present invention is to remedy this drawback and to this end it proposes a shutter curtain which, while being very resistant to hydrostatic pressure and to impact and capable of ensuring excellent sealing, does not hold in position. open with minimal space.
• the curtain comprises a succession of thin sheet metal elements of high inertia each consisting of a profile comprising a large central core and at least at one end a reinforcement making an angle with said core, the profiles having articulated connections and being designed in the open position of the curtain to fit into each other with minimal bulk and to be placed in a housing in a wall of the room and, in the position of closure, to be deployed across the passage, said sections being able to be fitted with sealing members automatically ensuring sealing between them in the deployed position of the curtain, and sealing means being able to be provided for sealing the curtain on the sides thereof, while actuating members ensure the operation of the curtain to pass from its open position to its closed position and vice versa.
• the profiles constituting the curtain according to the invention may have an L-profile, the reinforcing part being practically perpendicular to the core of the profile, and a hinge is arranged in the corner of the profile while being connected to the end of the 'central core of the previous profile.
• each profile may have at the ends of the central core two reinforcements substantially perpendicular to this core and directed either in the same direction (U-shaped profile), or in opposite directions (Z-shaped profiles), a hinge connecting together the adjacent reinforcements of two successive elements.
• the curtain moves from top to bottom, which allows an emergency maneuver by its own weight, and its elements have decreasing dimensions so that the lower elements, exposed to hydrostatic pressure or shocks (from vehicles for example), are more resistant.
• the device advantageously uses two inclined side walls, with inclined supports which serve as locks. Sealing is ensured by the pressure of the curtain on the seals carried by the side walls, due to the inclination of the seals relative to the displacement of the curtain.
• This sealing can be completed by a device for applying the seal, by gongling or by displacement of the support wall. This displacement of the wall can have a sufficient amplitude to bring it back to the vertical in order to have the maximum passage.

• the successive elements are connected together by a hinge 5 disposed in the corner of the profile and which cooperates with the end of the core 3 of the previous profile.
