Figure 1, according to an exemplary embodiment, the stabilizing section (110) consists of an extrusion of a metal material, such as a light alloy, or a composite material, resistant to corrosion. This extrusion comprises, in section, two wings (111, 112) support forming an angle between them, able to bear on the walls of a basin. When said profile is designed to be installed in the corner of a rectangular basin, the angle a is chosen equal to 90 °. When said profile is designed to take place on the flat wall of a basin, the angle a is chosen equal to 180 °. According to this embodiment, the bearing surfaces (115, 116) of said support wings on the wall of the basin are of reduced extent so that the support is achieved even if the wall of the basin is not perfectly flat. When, for example, the wall of the basin on which the stabilizing profile bears is curved, spacers (not shown) are interposed between said bearing surfaces (115, 116) and the wall, so as to compensate for this curvature. The stabilizing profile is assembled to the wall of the basin by any known means, not shown, such as by screws, by gluing or by sealing tabs. According to an exemplary embodiment, when the stabilizing section is placed in the corner of a basin, said section is simply placed against the walls of the basin without being fixed.

The two wings (111, 112) of support are connected by a chord (120) of guide, which chord delimits with the wings (111, 112) of support and the wall of the basin, a volume (130) said internal volume . According to this embodiment, the guide member is open over a large part of its length by a groove (121) made, for example, by machining. Figure 2, according to another embodiment, the stabilizing section is obtained by the assembly of several extrusions (210, 221, 222) performing similar functions. Thus, said stabilizing profile comprises a support profile (210) comprising two wings (211, 212) able to bear and able to be assembled by any means with the wall of a basin (not shown) and two half covers (221, 222) assembled, according to this embodiment, snapped onto the support profile 10 (210), which half-covers (221, 222) provide the guide member. The distance between the two half-covers (221, 222) creates the equivalent of the groove. According to this exemplary embodiment of a module (200) for controlling and guiding according to the invention, a geared motor (250) is fixed in the internal volume of the stabilizing profile, for example to the profile (210) of FIG. support. This geared motor (250) advantageously comprises a sealed motor, operating at a voltage of 12 volts, so that said motor is able to operate in a submerged manner. Said geared motor drives the pulley (260) whose sheave causes a cable (270) traction. A platen (240) carrying a rolling guide roller (245) on the half-covers (221, 222) is connected to said traction cable and moves, guided by the roller (245), along the stabilizing profile. when the geared motor is operated. Figure 3, the stabilizing profile extends over a length /, which length advantageously corresponds to the depth of the basin (not shown) in which said profile is installed vertically. According to an exemplary embodiment the geared motor (250) is fixed in the upper part of said stabilizing section. Under these conditions and according to an exemplary embodiment, a second pulley (360) is fixed at the bottom of the support section (210), the pulling cable (270) looping between the two pulleys (260, 360). inside the internal volume delimited by the stabilizing profile. According to this embodiment, the fastening means of the motor (250) or of the pulley (360) fixed in the profile, comprise means (not shown) for adjusting the tension of the cable (270), said cable performing, according to an exemplary embodiment, a dead turn around one of the pulleys (260, 360) so as to ensure efficient transmission of movement between the cable and the pulley, including when the device is immersed. According to other embodiments, the traction cable consists of a strap or a toothed belt. The geared motor (250), the traction cable (270) and the pulleys (260, 360) constitute a drive assembly of the platen (240). According to one embodiment (not shown) this drive assembly comprises more than two pulleys so as to make a muffle. This embodiment is suitable for maneuvering a heavy moving floor. FIG. 4, according to an exemplary embodiment, the plate (240) is constituted from a U-shaped section. A cable-clamping device (445) is welded to the base of this U-shaped section, projecting from the platinum, so that said device (445) secures the platen to the cable (270) in the internal volume of the stabilizing profile when the control and guiding module is assembled. The cheeks of the U-shaped profile support the roller (245) in pivot connection relative to said profile. The shape of the roller is adapted to the outer shape of the guide member. Advantageously, the roller (245) is of biconical shape so as to stabilize the plate (240) vis-à-vis the translations of axis parallel to the pivot axis of the roller when said roller rolls on the guide chord. According to an advantageous exemplary embodiment, the guide member comprises a circular portion and the roller (245) is in the form of a diabolo, that is to say it comprises two truncated cones, of a circular generatrix substantially equivalent to the profile. of the guide chord, connected by their small vertex. According to this embodiment, the bottom of the U-shaped profile forming the plate (240) comprises means (441), for example in the form of tapped holes, for connecting said plate (240) to a movable bottom.

Figure 5, according to an exemplary embodiment the device of the invention comprises a staircase (500) deployable. Said deployable staircase comprises steps (510) and risers (520). When the staircase is folded, the risers (520) are no longer visible and the steps (510) form a flat surface. When the staircase is deployed, the steps (510) move vertically relative to each other in relative translation along the risers (520) so as to form a stepped surface. For this purpose and according to an exemplary embodiment, each running assembly (510) and riser (520) is fixed on an angled section (521). Each angled section (521) is connected by a sliding pivot connection to a longitudinal rod (531) greater than one of its ends, on the walking side, and at its other end, to a lower longitudinal rod (532) on the riser side. The pivot axis (5211, 5212) of said links is perpendicular to the translation axis of these links, the pivot axes (5211, 5212) of the two links being parallel. The upper longitudinal rod (531) is connected to the wall of the basin (not shown) by a pivot connection along an axis (5321) perpendicular to said rod (531). The lower longitudinal rod (532) is connected to the movable bottom (not shown) by a pivot pivot pin pivot connection (5322) perpendicular to the translation axis of this link. This pivot connection of the end of the lower longitudinal rod (532) is formed by a wheel (540) connected to the end of this rod, which wheel is guided in a track materialized on the movable bottom (not shown). The axes (5211, 5212, 5321, 5322) of all the pivot links are parallel and remain it regardless of the position of deployment of the staircase (500). The longitudinal rods (531, 532) constitute with the brackets (521) supporting the steps (510) and risers (520) a deformable parallelogram, the axes (5211, 5212, 5321, 5322) pivot connections being normal to the surface of this parallelogram. The first step is fixed to the pool wall by appropriate means (511). According to this embodiment, two sets constituting such a deformable parallelogram support the steps and risers at their transverse ends. Alternatively, for the realization of a deployable staircase without risers a single assembly of this type is used in central position relative to the steps. 6, the wheels (540) for guiding the ends of the lower longitudinal rods (532) are engaged in guide tracks under the movable bottom (600), which guide tracks are represented by profiles (640), for example Figure 6A, when the movable bottom (600) is in the up position, the staircase (500) is folded and the steps form a flat surface. According to this embodiment, apart from the lower longitudinal rod (532) of said staircase (500), all the other elements constituting it are above the movable floor. This configuration allows in particular to install the staircase (500) deployable in an existing pool above an existing staircase, for example masonry, without modifying said basin. The downward movement of the movable bed (600) drives the rollers (540) downwards, causing the upper longitudinal rod (531) to pivot relative to the basin. The kinematics imposed by the joints of the deformable parallelogram causes the vertical shift of the steps. Beyond a certain vertical position of the moving bottom 5 (600) downhill, the rollers (540) out of the guides (640) and the movable bottom (600) then continues its descent without causing the staircase. The staircase (50) is then suspended. Referring back to FIG. 5B, a link (550) is slidably connected to the two longitudinal links (531, 532) in oblong grooves (551, 552). Beyond a certain position of deployment of the staircase (500) said link (550) abuts the end of said grooves (551, 552) stabilizing the staircase (500) in this position. Thus, the staircase is stabilized and usable even if it is no longer linked to the moving floor. When the movable bottom (600) is raised, the rollers (540) are again captured by the tracks (640), which go up the stairs (500) in the folded position. Figure 7, according to a particular embodiment, the deployable staircase (700) is of scalable width. Such a staircase (700) has the advantage of being able to be installed in the corner of a basin that does not have a staircase and to provide this advantageous function in combination with the movable floor, thus making it possible to eliminate the possible ladders. located inside the basin and which would hinder the operation of the device. The expandable staircase (700) of scalable width is functionally similar to the fixed width staircase and includes steps (710) and risers (720) attached to brackets (721) pivotably connected to a rod ( 731) and a lower longitudinal rod (732).

The rod (731) longitudinal upper is installed in pivot connection relative to the wall of the basin. The opposite end of the lower longitudinal rod (732) is connected to the movable bottom by a sliding pivot connection made by rollers (740) moving in tracks (not shown) materialized under the movable bottom. The longitudinal rods (731, 732) and the brackets (721) supporting the steps constitute a deformable parallelogram. The first step is fixed to the wall of the basin by means (711), and a connecting rod (750) stabilizes the stair (700) in the deployed position. When a set forming a deformable parallelogram is installed at each transverse end of the scalable staircase (700), these two sets are not parallel as in the case of the fixed width staircase but form between them an angle a corresponding to the angle of the corner in which said staircase (700) is installed. Figure 8, according to an exemplary embodiment for the installation of a movable floor (600) in a rectangular basin, the installation comprises 4 modules (200) for control and guidance installed vertically in each corner of the basin. The movable bottom (600) is connected to each of these modules via the plates of said modules (200). Each module comprising autonomous motorization means, the synchronization of the movements of the various modules is advantageously achieved by means of a WIFI type radio wave link between the various modules (200). In the same way, the control of the device is advantageously carried out by means of a radio remote control. Thus, according to this embodiment, the installation can be performed without wire connection. When the basin is of any shape or when the movable bottom is intended to support high loads, as many modules (200) as necessary are installed. To ensure the stability of the mobile bottom at least 3 modules must be installed in the basin to support and maneuver. Figure 9, the installation of Figure 8 is installed in combination with a staircase (500) deployable in a basin (900) comprising a recess (910). In order to limit wired installations and installation work, the geared motors and the control devices of the modules are powered by rechargeable batteries recharged by photovoltaic means. The stability of the movable bottom (600) in the high position is advantageously secured by means of locking devices (not shown) 25 of said movable bottom (600) with the wall of the basin (900). These locking devices are manually controlled or radio-controlled according to the embodiment. The movable bottom (600) is here represented according to an embodiment comprising a floor of blades (610) placed on a structure (620) in a joist. This embodiment is more particularly adapted to the production of a floor capable of forming a terrace in the high position of the moving floor. Alternatively, the mobile bottom consists of a lighter cover, see a simple net.

The above description and the exemplary embodiments show that the invention achieves the desired objectives, in particular it allows an aesthetic and autonomous installation of a mobile floor in an existing pool, without modifying the structure of said basin even when the latter includes stairs. The invention is adaptable preferentially to a pool but can be easily adapted to any type of ornamental pond or industrial vocation.
