Definitions

  • the present invention relates to the field of swimming pools, and more particularly that of automatic cover devices for a swimming pool basin.
  • the invention is particularly suitable for a pool basin comprising a wall with non-right angles.
  • An automatic cover device for a swimming pool basin constitutes a protection making it possible to prevent debris, leaves or other dirt from falling into the swimming pool basin but also a safety device against drowning in the event of an accidental fall, for example of a child less than 5 years old.
  • An automatic cover device also keeps the pool water warm at night. For all these reasons, the use of automatic cover devices for swimming pools has developed.
  • an automatic pool basin cover device consists of a rolling shutter and comprises a floating apron - or cover - consisting of a plurality of floating slats assembled together.
  • the apron is adapted to be wound around a winding/unwinding axis (hereinafter “the axis”), for example a tube.
  • the axis a winding/unwinding axis
  • the floating apron In the "closed pool” position (hereinafter “closed position”), the floating apron is in the unrolled position: the floating apron is deployed on the surface of the water to cover the pool.
  • the floating apron In the "open pool” position (hereinafter “open position”), the floating apron is stored, rolled up around the winding/unwinding axis, leaving access to the pool free.
  • the swimming pool basin cover device can be arranged outside the swimming pool, possibly just at the edge of the swimming pool, the apron being rolled up around the axis in the "open swimming pool” position and then being out of the pool.
  • one way of proceeding is to fix transversely, on either side of the swimming pool basin and under the surface of the water, fixing means making it possible to fix the winding axis and possibly to other constituent elements of the covering device, such as a box covering the axis.
  • the role of the box can be aesthetic, by hiding the axis and the floating apron in the open position.
  • the casing can also contribute to safety by preventing access to the cover device and/or allowing a pool user to stand on it.
  • the floating apron In the open position, the floating apron is wrapped around the axle and is submerged.
  • FIG 1 illustrates such a cover device installed in a swimming pool 100.

  • the basin comprises a first wall A and a second opposite wall B, the walls A and B being able to delimit a length of the basin.
  • the covering device arranged close to a first wall (here, wall A), comprises a floating apron 110, or cover 110, here shown almost completely rolled up around a winding axis (the axis is therefore invisible) and comprising a plurality of floating slats assembled together.
  • the cover device illustrated comprises a box (or covering) consisting of a platform 150 supported by beams 130 and 140.
  • the platform 150 is for example a grating.
  • Platform 150 may include a grating or floor allowing a pool user to stand or sit on it.
  • the platform 150 is placed above the axle and therefore covers the axle and the floating deck wrapped around the axle when the cover device is in the open position.
  • the covering device also includes a vertical dividing wall 160 (partially shown in the figure 1 ), located at the front of the platform 150, separating the covering device from the pool itself.
  • the vertical dividing wall 160 and the platform 150 form a box covering the winding shaft and making it possible to protect it, particularly when the floating apron 110 is rolled around in the open position.
  • Platform 150 is typically located a few centimeters below the surface of the water so that the floating apron 110 can pass over it when unrolled.
  • the winding axis as well as the beam 140 are supported by flanges, or fixing means for the cover device, 120A and 120B fixed to the walls of the pool basin.
  • FIG 2 illustrates a profile view of the cover device of the figure 1 .
  • the axis 270 is located close to a wall of the basin delimiting the length of the basin of the swimming pool 100 (here, the wall A).
  • the platform 150 comprises a rear end, on the side of the wall A of the basin and a front end, shown in the figure 2 placed on the vertical partition wall 160.
  • An opening is provided for the passage of the floating apron 110 between the wall A and the rear end of the platform 150.
  • the direction of rotation of the winding/unwinding axis is chosen in order to allow the floating apron 110 to be unwound along the wall A of the swimming pool so that the apron 110 can pass through the opening located between the wall A of the basin and the rear end of the platform 150.
  • the rocking of the free end of the floating deck 110 on the right side can be obtained by means of a ballast placed in this free end or thanks to the shape of the free end.

  • the free end of the floating apron 110 is in abutment against the wall B, and the end of the floating apron 110 connected to the axis 270, possibly via straps or straps, is in abutment against the wall A.
  • the cover device For the cover device to be accepted as a safety cover, it must meet a safety standard, for example the NF P90-308 standard defined by AFNOR (“Association facie de NORmalisation”). According to most standards, access to the mechanisms of a cover device must be protected.
  • the standard NF P90-308 defines more specifically that the horizontal opening through which the floating deck 110 passes between the wall A and the rear end of the platform 150.
  • This opening is a free passage, that is to say not closed by a valve or a shutter, whose mobility between an open position and a closed position would make it possible to selectively create an opening or protection against access to the floating apron.
  • This passage being left free, the standard indicates that it must have a maximum width “d” less than a predetermined value.
  • This predetermined value can be defined by a standard, for example standard NF P90-308. This predetermined value is for example equal to 80 mm according to standard NF P90-308 published in 2013.

  • a floating apron 310 intended to cover the surface of the basin in the closed position comprises, for a large part, floating slats having a width equal to the width of the basin.
  • the winding axis 370 cannot therefore be installed too close to the wall A so that the apron 310 is not rolled up or unrolled in the zone 380, said zone 380 not being wide enough for the passage of the slats of the floating deck 310.
  • the minimum width of the opening of width "d" through which the deck 310 passes between the wall A and the rear end of the platform 350 is therefore constrained by the rounded corners formed at the junction of the walls vertical of the basin.

  • FIG. 9 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a third intermediate position.
  • FIG 9 represents a situation in which the apron 610 has come into abutment against the wall B and in which the apron 610 has partially unrolled towards the wall A.
  • the still submerged part of the apron 610 has gradually unrolled on the surface of the pool, towards wall A.
  • End G of the apron 610 attached to the axis 670 by means for example of straps 690 is here represented as having come out of the box of the covering device 600.
  • a circle of curvature C of the floating apron 610 is represented by dotted lines in the figure 9 .
  • the radius of curvature of the floating apron 610 corresponds to the radius of the circle of curvature C.
  • the height "h” is determined so that the floating apron 610 can form a loop above the platform, the height "h” must therefore be greater than or equal to the diameter of the circle of curvature C, i.e. twice the radius of curvature of the floating deck.
  • the submerged part of the floating apron 610 cannot deploy correctly on its own and remains stuck under the part of the floating apron 610 already unrolled on the surface.
  • the covering device 600 cannot then entirely cover the surface of the basin without an additional action. It is then possible for a user to finish deploying the floating apron 610 “by hand”, for example by pulling on it and/or by helping the unrolling of the apron by lifting it in the last phase of unrolling.
  • the height "h" may be slightly less than the diameter of curvature of the floating deck, the floating deck 610 being able to protrude marginally above the surface of the water when winding/unwinding above the 650 platform.
  • FIG 10 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a fourth intermediate position.
  • FIG 10 represents a situation in which the floating apron 610 has come into abutment against the wall B and in which the apron 610 has unrolled towards the wall A.
  • the still submerged part of the apron 610 has gradually unrolled on the surface of the basin the wall A.
  • the end G of the apron 610 attached to the axis 470, by means for example of straps, is here represented as having come out of the box of the covering device 600 and approaching the wall A, the apron 610 positioning itself by virtue of its buoyancy on the surface of the pool.
  • FIG 11 illustrates side and top views of the cover device 600 of a swimming pool basin according to one embodiment of the invention, the cover device 600 being in a closed position.
  • FIG 11 represents a situation in which the apron 610 has come into abutment against the wall B and against the wall A.
  • the apron 610 completely covers the surface of the pool basin, the cover device 600 is in its closed position.
  • the end E of the floating apron 610 abuts against the wall B and the end G of the floating apron 610 abuts against the wall A.
  • the cover device 600 can return to its open position, illustrated in the figure 6 , by rotating the axis 670 in the other direction than the direction of rotation F in order to wind the apron 610 around the axis 670.
  • the apron 610 takes the different intermediate positions illustrated in the figures 10 to 7 , in the reverse order of the order previously described for the unwinding of the apron 610 towards the closed position.
  • the shape of the free end E of the floating deck 610 is designed to come into abutment against the wall B.
  • the shape of the end G of the floating deck 610 is designed to come into abutment against the wall A.
