  • Patent number: 9546492
    Abstract: The invention relates to a device (1) for covering a surface (3) of which the contour defines a surface plane, said device comprising: (a) a substantially rectangular cover (10) wound onto (b) a drum (2) which is rotatably mounted on a carriage that can wind up or unwind the cover (10) by movement of the carriage in a longitudinal direction of the surface and thus allows the deployment of the cover or the removal thereof from the surface (3); and (c) a protective casing (20) mounted on said carriage, characterized in that the distance between the edge of the casing and the edge of the surface varies between a first stopping position dp, and a second movement position dm when the carriage moves the drum over the surface (3), and in that dm>dp.

  • Patent number: 8272425
    Abstract: The invention relates to a flexible shutter device, designed for closing a bay or other opening which cooperates with drive means which permit a displacement of the flexible shutter between an open position and a closed position. The device comprises a drum which may turn about the axis thereof and about which the flexible shutter is wound in the open position thereof, forming a roll comprising turns made up of successive layers attaching one to the other and from which the flexible shutter can be unwound and pushed into the closed position thereof. Slides mounted on a fixed support provide guidance along the bay for the unwound part of the flexible shutter. Pressure or restriction elements (33, 50, 66) avoid buckling of the lateral edges (2,3) in the supported part thereof, extending between a first end (30) of the slides (4,5), nearest the roll and the roll.

    Abstract: The invention relate to a flexible shutter device, designed for closing a bay (6), cooperating with drive means which permit the movement of the flexible shutter (1) between an open position and a closed position. The device comprises a drum (8) which may turn about the horizontal axis (11) thereof and about which the shutter is wound in the open position forming a roll of turns of successive layers of the shutter attaching one to the other and from which the flexible shutter can be unrolled and pushed into the closed position thereof. Suspension means for the drum comprise a suspension axis (13) parallel to the axis of rotation of the drum about which the rotational axis of the drum can oscillate. Contact elements (16, 36) exert a driving force on the roll essentially radial with relation to the drum.
