Definitions

  • the invention relates to a method of covering, by a floating curtain, the surface of the water of a swimming pool.
  • a curtain winding element is attached to the ground at one end of the pool so that the axis of a rotating winding drum of the curtain is located above the surface of the water to immediate proximity of the edge of the pool corresponding to said end.
  • the rotating drum is rotated to unwind the curtain in a vertical plane, relative to the drum axis, on the side of the pool edge, until the curtain covers the entire surface of the pool. water.
  • the gap between the edge of the pool and the axis of the rotating drum is sufficient for the passage of the curtain.
  • the covering of the surface is thus achieved by the rotational actuation of the rotary drum, which generates a corresponding displacement of the free end of the curtain by floating on the water towards the end of the pool opposite the winding element.
  • the displacement of the free end is accompanied by a gradual increase, from the end of the pool where is fixed the winding element, the floating curtain surface. This increase corresponds to a gradual recovery of the water surface from the end of the pool where the winding element is fixed, covering which is practiced in only one direction of recovery over the entire length of the pool, according to a direction of recovery horizontal and perpendicular to the axis of the drum.
  • Such a method of recovery is however not entirely satisfactory. Indeed, it can not be applied to a pool whose edges substantially oriented in the direction of recovery have divergent portions in the direction of recovery. On the other hand, it is only applicable to a pool having small dimensions because, otherwise, the effort required to generate the increase of the floating curtain surface (especially at a stage near the total recovery) is too high.
  • the purpose of the invention is a method of covering a swimming pool that overcomes the above disadvantages.
  • the method according to the invention allows to practice the recovery, starting from the junction of the two zones, of the first zone in a first direction of overlap and then of the second zone in a second overlapping direction opposite to the first zone.
  • the recovery of the first zone is practiced by a displacement by floating in the first direction of recovery, while the recovery of the second zone is achieved by a progressive deposition of the curtain in the second direction of recovery.
  • the winding element for the implementation of the method is remarkable in that the structure is shaped as a retractable and autonomous trolley with a stiffening beam connecting the two feet parallel to the rotary drum, each foot having at least one rolling element on the ground, and that one of the poles is provided with a housing for a motor battery, and a cable tray for electrical connections to the motor.
  • This structure comprising such rolling elements constitutes a retractable carriage.
  • the on-board battery pack gives the truck a stand-alone character.
  • FIGS 1 to 3 illustrate a winding element 10 of a floating curtain 11 (shown only on Figures 4 to 6 ) used for the implementation of the recovery method according to the invention. The process will be described with reference to Figures 4 to 6 .
  • the winding element 10 comprises a structure supporting the ends of a rotating drum 14 for winding the floating curtain 11.
  • the structure comprises two feet 12, 13 resting on the ground. Each end of the drum 14 is supported by one of the legs 12, 13 of the structure.
  • An electric motor (not shown) is housed in the rotary drum 14 to ensure its rotation.
  • the supporting structure of the drum 14 comprises at least one stiffening beam 15 connecting the two legs 12, 13.
  • the stiffening beam 15 is parallel to the rotary drum 14.
  • the main axis of the rotary drum 14 defines the longitudinal direction D1 ( figure 1 ) of the winding element 10.
  • the planes perpendicular to the longitudinal direction D1 are transverse planes of the winding element 10.
  • Each foot 12, 13 comprises a pole 121, 131, for example vertically disposed, whose lower end is fixed to the middle portion of a cross member 122, 132 disposed horizontally.
  • the drum end 14 supported by said foot 12, 13 is fixed close to the upper end of the pole 121, 131 of said foot 12, 13.
  • Each foot 12, 13 comprises at least one rolling element 123, 133.
  • at least one rolling element 123, 133 is interposed between each leg 12, 13 and the ground. More specifically for the example shown, two rolling elements 123, 133 are interposed between each cross member 122, 132 and the ground.
  • the two rolling elements 123, 133 associated with this cross member 122, 132 are disposed near the two opposite ends of said cross member 122, 132.
  • each rolling element 123, 133 is made using a wheel rotatably mounted on an axis of rotation 124, 134 fixed relative to the structure.
  • the set of axes of rotation 124, 134 of the wheels are parallel to the rotary drum 14 supported by the structure. Nevertheless, each rolling element 123, 133 can be produced by means of a wheel rotatably mounted on an axis of rotation itself mounted to free rotation on the cross-member 122, 132 along a vertical axis.
  • the fixing of the axis of rotation 124, 134 on the crosspiece 122, 132 may comprise a compensation mechanism in height (not shown) to overcome the consequences of the hyperstatic character of the support at four points of the structure On the ground.
  • the axis of rotation 124, 134 can be mounted with vertical direction linkage slide while a pressure spring can constantly apply a compression force directed towards the ground on said axis 124, 134.
  • at least one of the rolling elements 123, 133 can be motorized.
  • the supporting structure of the drum 14 is shaped as a retractable carriage by rolling thanks to the rolling elements 123, 133.
  • the stiffening beam 15 which is provided with the carriage and connecting the two legs 12, 13 gives a very high rigidity to the carriage while driving.
  • one of the posts 121, 131, here the pole 121 is provided with a housing 16 for a battery 17 for powering the motor housed in the drum 14.
  • This pole 121 enclosing the battery 17 comprises on the one hand a cable tray 18 for the electrical connections 19 to the motor, and on the other hand key control means 20 electrically connected between the motor and the battery pack 17.
  • An electrical socket 21 electrically connected to the battery of power supply 17 and accessible from outside the pole 121 allows the connection to an external charging means (not shown) to recharge the battery 17.
  • Such electrical power and control of the engine gives an independent character to the carriage constituted by the structure described above.
  • the winding element 10 is used to carry out the covering of the water surface of a swimming pool (marked 22 on the figure 1 ) according to the method of the invention, described below: from a storage location advantageously remote pool 22 to limit congestion and inconvenience the operator positions the winding element 10 (on which the floating curtain 11 is wound up unlike the configuration of the figure 1 ) across the pool 22 in a working position (see Figures 4 to 6 ) intermediate between two opposite edges of the pool 22.
  • rails 23 rectilinear and parallel may be fixed projecting from the ground to guide the rolling elements 123, 133 during the rolling of the trolley.
  • the rails 23 have a circular section while the wheels of the rolling elements 123, 133 each comprise a peripheral groove of arcuate section whose radius corresponds to the section of the rails 23.
  • the variant in which the axes of rotation 124, 134 are mounted to freely rotate on the cross member 122, 132 along a vertical axis allows the use of non-rectilinear rails.
  • each leg 12, 13 may comprise an indexing element (not shown) vertically movable to ensure a predetermined positioning of the winding element 10 relative to the pool 22 by depressing the indexing element in a corresponding hole in the ground.
  • An equivalent result can be obtained by making a stop on each rail 23 at the location corresponding to the position occupied by the wheel of the rolling element 123, 133 when the winding element 10 is in the working position.
  • Such an abutment can be arranged as a projection of the rail 23, or by digging.
  • the winding element 10 In the working position, the winding element 10 is positioned above the surface of the water and fictitiously divides the surface of the water into a first zone A and a second zone B.
  • the longitudinal direction D1 of the winding element 10 coincides with a lateral direction D3 of the pool 22 which is perpendicular to a longitudinal direction D2 of the pool 22 (see FIG. figure 1 ).
  • Each foot 12, 13 rests on the ground near a edge 222, 223 of the pool 22, the edges 222, 223 being opposite in the lateral direction D3 of the pool 22.
  • the pool 22 To have a closed shape, the pool 22 must have two opposite edges in the longitudinal direction D2 of the pool 22 ( of which only one 221 is shown).
  • Zones A and B are adjacent by a junction J parallel to the longitudinal direction D1 of the winding element 10 and to the lateral direction D3 of the pool 22.
  • the operator actuates in rotation the rotary drum 14 to unwind the curtain 11 in a vertical plane P (see figure 4 ), to a first position (not shown) of the curtain 11 where the free end 24 of the curtain 11 is in contact with the surface of the water at the junction J.
  • the operator continues the rotation of the drum 14 to move the free end 24 of the curtain 11 along the first zone A in a first overlap direction S1: the rotary actuation of the rotary drum 14 generates a displacement (corresponding to the unwinding the curtain 11 in the plane P) of the free end 24 of the curtain 11 by floating on the water towards one (predetermined) opposite edges in the longitudinal direction D2.
  • the displacement of the free end 24 is accompanied by a gradual increase, since the imaginary junction J, of the floating curtain surface 11. This increase corresponds to a progressive recovery of the water surface from the junction J, overlap which is practiced in the direction of recovery S1 along the entire length of the first zone A, in a recovery direction coinciding with the longitudinal direction D2.
  • the figure 4 illustrates the floating curtain 11 and its winding element 10 during this movement of the curtain 11.
  • the rotation of the drum 14 is extended to a second position of the curtain 11 (not shown) where a first curtain portion 11 covers the whole of the curtain 11 the first zone A, and where a second curtain portion 11 comprises a first portion in the plane P and a second portion still wound on the drum 14.
  • the overlap of the first zone A is made from the junction J in a first overlap direction S1.
  • the covering of the first zone A in the first covering direction S1 is practiced by a progressive horizontal displacement of a portion of the curtain 11 by floating from said junction J, this part in contact with the water increasing during its displacement.
  • This operation is practiced by successively depositing the first curtain portion 11 (that placed in the plane P in the second position of the curtain 11) starting from the junction J, then the second portion (the one still wound on the drum 14 in the second position of the curtain 11) on the remainder of the second zone B: as the free end 24 of the curtain 11 is in abutment and that the winding element is held fixed relative to the pool 22, the rotational actuation of the rotary drum 14 from the second position gradually generates a bulge of the second part of the curtain 11 (corresponding to its unwinding movement) on the side of the zone B with respect to the plane P.
  • This progressive bulging of the second part of the curtain 11 is accompanied concomitantly with the deposit of the first portion then the second portion.
  • This successive deposit is made starting from the junction J and towards the opposite edge 221 in the longitudinal direction D2 to the abutment edge at the free end 24, which corresponds to a second overlap direction S2 opposite to the first S1.
  • This increase corresponds to a progressive recovery of the water surface from the junction J, recovery which is practiced in the direction of recovery S2 on all the length of the second zone B, in the same overlap direction as that of the first zone A.
  • the figure 5 illustrates the floating curtain 11 and its winding element 10 during this movement of the curtain 11.
  • the arrow F1 illustrates the direction in which the second part of the curtain 11 is gradually dropping during the rotation of the drum 14.
  • the figure 5 shows that flexible links 25 connect the drum 14 to the end 26 of the curtain 11 opposite the free end 24.
  • the rotation of the drum 14 has the effect of s against the weight of the curtain portion 11 released and still emerged, through the flexible links 25 under tension during the retention of the end 26.
  • the actuation in rotation of the drum 14 after the release of the curtain 11 since the drum 14 corresponds to the transmission to the drum 14 of a resistant pair of progressively decreasing value to generate the progressive deposition of the still emerged portion at the time of said release.
  • each flexible link 25 consists of a strap having a first end connected to the drum 14 and a second end provided with a first part of a manually reversible locking quick-fastening device, the first part being adapted to cooperate with a second part of said quick fastening device attached to the end 26 of the curtain 11.
  • the rotation of the drum 14 is extended to a third position of the curtain 11 ( figure 6 ) where the curtain 11 covers the entire pool 22.
  • the second part of the curtain 11 covers the whole of the second zone B, and the flexible links 25 rest on the curtain 11 in the second zone B.
  • the method according to the invention allows to achieve successively starting from the junction J of two dummy zones A and B, covering the first zone A in a first overlap direction S1 and then covering the second zone B in a second overlapping direction S2 opposite the first one.
  • the covering of the first zone A in the first overlapping direction S1 is practiced by a progressive horizontal displacement of a portion of the curtain 11 by floating from said junction J, while the overlap of the second zone B in the second direction of overlap S2 is produced by progressively depositing the remainder of the curtain 11 from said J junction.
  • the first and second overlapping directions S1, S2 are therefore collinear and opposite in the same direction of overlap, which is perpendicular to the axis of the rotary drum 14 when the winding element 10 is in the working position.
  • the edges of the first zone A (which is directly related to the choice of the working position) substantially oriented in the overlapping direction have only portions convergent or parallel in the first covering direction S1.
  • the edges of the second zone B (also depending on the choice of the working position) substantially oriented in the direction overlap can be any.
  • the edges of the second zone B may in particular comprise divergent portions in the second overlap direction S2.
  • any pool 22 may be covered by the method according to the invention, whatever its shape, since it is possible to determine a working position ensuring a fictitious decomposition of the floating curtain 11 into a first part that can be put in place over the whole of a first zone A of the surface of the water by progressive floating in a first direction of recovery S1, and in a second part which can be put in place on the whole of a second zone B by progressive deposition in a second overlapping direction S2 opposite the first.
  • the covering method according to the invention also has the advantage that only a portion of the floating curtain 11 is put in place by a progressive displacement by floating. Only the implementation of this part is likely to present difficulties (depending on its size). Indeed, the remaining part of the curtain being put in place by simple deposit, this operation presents no problem whatever its dimensions.
  • the method according to the invention thus allows the recovery of swimming pools having dimensions significantly greater than the possibilities of the prior art.
  • the deposition of the second curtain portion is practiced by a progressive curvature of the curtain while the drum is unrolled and the winding element is held fixed .
  • the progressive deposition of the second part of the curtain is practiced, simultaneously with the unwinding of the drum in order to gradually release the second part of the curtain, by a displacement of the winding element 10 from the position of work towards the edge 221 of the pool opposite the abutment edge at the free end 24.
  • This movement of the winding element 10 during the recovery of the second zone of the pool by progressive deposition can be achieved manually or by using the motorized rolling element 123, 133, or else may be a consequence of the fact that the electric motor operating the rotating drum 14 rotates the drum while the free end 24 bears and that the rolling element 10 is released longitudinally from any indexing positioning means.
