Definitions

  • the present invention relates to a cover device for a swimming pool, or rigid basin, and more particularly to a submersible multi-panel cover device.
  • swimming pools and in particular open-air swimming pools, are provided with a cover which is placed on their opening during periods of non-use.
  • This cover makes it possible, in particular, to prevent dead leaves, or other foreign bodies transported by the air, rainwater, etc., from polluting the basin and making it unsuitable for swimming.
  • Such a cover if it is designed to be sufficiently resistant, also constitutes a safety element against accidental falls, particularly that of children.
  • a cover also makes it possible, inside, to improve the comfort of the swimming pool, by reducing the humidity in the room in which it is placed and, outside, to reduce the heat losses which usually occur during the night.
  • the object of the present invention is to remedy these drawbacks by proposing a device making it possible to cover a swimming pool which is rigid enough to allow, outside periods of use of the swimming pool, to use the upper surface of the latter to d 'other applications, which is easy and quick to implement, which is aesthetic, and which, finally, or a relatively affordable manufacturing cost.
  • a subject of the present invention is therefore a cover device for a swimming pool, movable vertically inside the swimming pool, between two extreme positions, namely the bottom and the surface thereof, under the action of displacement means, this device comprising shutters movable mounted on a support structure so as to be able to occupy an open position and a closed position, characterized in that the support structure is flat and rigid and forms a multiplicity of partitions, each partition being closable by at least one flap, the displacement means being able to position and maintain the structure in at least a third position, located between the above extreme positions.
  • the means for vertical displacement of the support structure consist of a plurality of scissor elements, namely of X-shaped elements consisting of two articulated uprights, the upper ends of which are slidably mounted in said support structure and ensure the maintenance thereof, and the lower ends are supported on the bottom of the pool, on elements movable in the plane thereof, which allow either to bring said ends together lower to raise the support structure, or move them apart to lower the latter structure.
  • the mobile elements consist of flanges respectively integral with an upper rack whose teeth are directed downwards and a lower rack whose teeth are directed upwards , these two racks being engaged with gear means, arranged between the two racks so that, when one of the racks moves in one direction, during the rotation of the gear means, the other rack moves in opposite direction.
  • the mobile elements consist of two opposite parallel structures which extend in one of the longitudinal or transverse directions of the basin, on which are fixed parallel carriages which extend perpendicularly to said structures and which are alternated so that two adjacent carriages belong to opposite structures, the respective bases of the uprights of the same scissor element being mounted articulated on two neighboring carriages so that any parallel relative movement of the two structures causes an identical displacement of the base of the uprights.
  • the movable flaps are articulated around respective parallel axes which are pivotally mounted on vertical edges integral with the transverse elements constituting the support structure, the movable flaps having a shape such that they overlap at least in one direction.
  • Figure 1 is a partial vertical and cross sectional view of a swimming pool equipped with a cover device according to an embodiment of the invention.

  • a metal profiled element 34 is arranged, as shown in Figures 1,6,7, on the bottom 7 of the pool 1 of the pool, parallel to each of the transverse beams 13 to the right thereof.
  • the profiled element 34 is formed of two hollow profiled elements of rectangular section which are joined to their bases, namely a profiled element 40 and a profiled element 43.
  • the profiled element 40 is shared, by a horizontal partition 42, in a lower chamber 44 and an upper chamber which constitutes an upper slide 45.
