Abstract: A device for covering a surface includes a cover (9), a drum mounted to rotate and able to wind or unwind the cover, and a translation system. The translation system includes a pair of closing spools (11r) mounted to rotate about a closing shaft (12) and each coupled to a closing cord (1c) to move the drum on rails (6) in a closing sense (Dc), and an axle shaft (12) coupled to the drum (2t) the rotation of which enables winding of the cover onto the drum (2t) and to move the cover on the rails in an opening sense (Do). A motor (M) connected to a driving shaft (10M) and coupled to a clutch system is configured to enable the driving shaft to actuate alternately rotation of the closing shaft (11) and the axle shaft (12).

Abstract: A device for covering a surface includes (a) a covering, each longitudinal edge of which is provided with a projecting element; (b) a rotatably mounted drum suitable for rolling up or unrolling the covering, and movable in translation on rails placed on either side of the surface; (c) a system for continuously locking/unlocking the projecting element in the rails during the translation of the drum. The projecting element includes a multitude of discreet elements distributed along each longitudinal edge separated from one another by an average distance (d).

Abstract: A device for covering a is provided that includes (a) a cover, each longitudinal edge of which is provided with a protruding element; (b) a drum mounted so as to rotate on frames and capable of winding the cover; (c) a translation system for translatably moving the drum on rails that are placed on either side of the surface; (d) a system for continuously locking/unlocking the protruding element into/from the rails during the translation of the drum. The translation system includes: —a first rotation means (M1) for activating the rotation of a closing axle that winds a pull cord (21) enabling the drum to be pulled in an opening direction (Do) along the rails. The drum (2) is translatably mounted so as to also be moved in translation along a component perpendicular to the plane (X, Y) so that the drum always rests on the surface or on the rails.

Abstract: A device for covering a rectangular surface is provided that includes a cover (10) rotatably mounted on a drum (2), the device being capable of winding and unwinding the cover between an uncovered position and a covering position, rails (6) attached along the longitudinal sides of the surface, each of the rails includes an opening (6o) allowing the longitudinal edges (10L) of the cover to be locked in an air-tight manner, a blower system (51) suitable for blowing air (51a) into a volume under the cover and a flap (41) having an end (41s) which is sealed over a whole length of the second transverse side of the surface, a free end (41L) opposing the sealed end, such that the free end of the flap is in contact with the surface, the flap forming an air-tight seal between the cover and the surface along the second transverse side thereof.

Abstract: A device for covering a surface including a substantially rectangular cover (10) having first and second longitudinal edges each provided with a protruding convex bead (12) having a minimum diameter (d), two rails (6) including a groove, the opening (14) of which has a maximum width (Lo), a drum (2) that is able to move above the surface in order to deploy or retrieve the cover, an insertion system (16) for continuous insertion of the convex bead (12) into the groove. The convex head (12) of each longitudinal edge and the groove of the corresponding rail are configured such that, once inserted into the space (14e) by the insertion system, the convex bead occupying the space alone cannot be removed solely by the action of a force (F) applied parallel to the transverse axis (Y) in the direction of the surface to be covered.

Abstract: A device (1) for covering a surface is provided. The device includes: (a) a cover (10) of which each longitudinal edge is provided with a bead (12); (b) a rotatably mounted drum (2) capable of winding or unwinding the cover, movable on rails placed on either side of said surface; and (c) a system for continuously locking/unlocking the bead in the rails during the translation of the drum.

Abstract: A device for covering a surface and includes: (a) a covering of which each longitudinal edge is provided with a longitudinal strip ending in a flap; (b) a rotatably mounted drum capable of winding or unwinding the covering, and movable on rails placed on either side of said surface; (c) a system for continuous locking/unlocking of the flap in the rails during the translation of the drum, in which the covering includes at least one flap which makes it possible to isolate the portion of the longitudinal strip corresponding to the stuck flap portion, either from the atmosphere contained between the inner surface of the deployed covering portion and the covered surface portion, or from solar radiation.
