DETAILED DESCRIPTION OF THE INVENTION
The idea underlying the invention is a modest background bile with compartments that can be selectively filled with air to float it up, or well filled with water to make it sink to the bottom of the basin.
As shown in Figure 1, the movable floor the invention which is identified by 1 is intended to equi-pool 2 being installed inside the basement.
sin 3 of this pool 2. This mobile bottom 1 can occupy a lower position as in Figure 1 in the-which it rests on the bottom of this basin, and a posi-in which he is at the level of the sur-face 4 of the water 6 as in the case of Figures 3 to 5.
This moving bottom 1 here comprises a central compartment tral 7, and two lateral compartments 8 and 9 located on both sides of the central compartment 7 to be respectively near two opposite edges of the basin 3, these compartments being intended to receive air and / or water.
It furthermore comprises, at an angle of sin, an arm 11 that extends under a set of three steps 12, 13, 14 constituting a staircase 16 access to basin, when the body of the mobile bottom 1 is in position.
as in Figure 1.

6 These three steps 12, 13 and 14 are vertically movable calmly independently of each other, by being example mounted sliding each between two rails of vertical guidance. Each market also includes a internal compartment that can be filled with water for place in the lower position as in Figure 1, or filled with air to float back as in Figures 2 to 4.
When the three steps 12, 13 and 14 are in low, they constitute the staircase 16 which allows to go down to Basin 3, and when they are upper position, the upper faces of these three mar-are at approximately the same height, above the calf of water surface 4 of water 6 of pond 3.
As indicated above, compartments 7, 8, 9 of the structure of the movable floor 1, and the compartments of each step 12, 13, 14 contain water and / or air, and controlled means are provided to manage the amount of air contained in each compartment.
Each compartment constitutes an archi-mediate: it includes on the one hand an opening at the level of its lower region to continuously allow the and the outlet of water, and on the other hand an orifice level of its upper region to allow the exit of air, and it is further connected to a controlled source supply air.
This power source provides air to a pressure slightly above the atmospheric pressure that, an absolute pressure of the order of 1.2 bar being normally sufficient to lift the moving floor from the bottom of a basin having a depth of two meters.

7 The air can come from a compressor connected to different compartments by a network of tubes arranged in the structure of the moving floor. This air lightly pressurized can be produced by venturi effect, using a stream of water from the regeneration and filtration system water treatment of the pond.
The air supply source can be ordered to inject air with a flow rate greater than the flow rate permitted by the upper orifice, which causes a first time the water outlet through the lower opening, the air is placed in the upper part of the compartment.
The maintenance of air in the compartment is then assured by maintaining in service the power source in air, that is to say by continuing to inject air to renew the air evacuating through the upper orifice, also by the lower opening.
As understood, the stopping of food air allows the evacuation of all the air contained in the compartment through its upper orifice, as the water comes naturally take the place of the evacuated air.
Another possibility is to provide a valve ordered or a valve ordered to open or close the upper orifice. In this case the maintenance of air in the compartment simply needs to maintain the closed, and the evacuation of the air is obtained in mandating this valve opening.
Starting from the situation of Figure 1 in the-which the mobile bottom 1 is in the lower position in having all its compartments filled with water, its rise to a higher position is ensured by injecting

8 of air sequentially in its different compartments.
buildings.
First, air is injected on the one hand in one of the two lateral compartments, namely the compartment 8 which is farthest from the stairs 16, and on the other hand in the compartments of each of three steps 12, 13, 14. The compartment 8 constitutes as well a float boot of movement that allows to lighten the movable bottom 1 of the side opposite the steps 12, 13 and 14.
At the end of this first phase, the mobile bottom 1 occupies an inclined position corresponding to that of the FIG. 2. The edge of this moving bottom 1 which is opposed to that of the staircase 16, namely the nearest edge compartment 8 which is filled with air, is in upper layer above water surface 4 6.
The other edge, namely the edge that is closest to the staircase 16 is him in the lower position, so that the arm 11 is located at the bottom of the basin, with the plumb of the three steps 12, 13, 14 which are in position superior because their compartments are filled air.
Once the inclined position of Figure 2 has has been reached, the system is ordered to inject the air in the second lateral compartment, namely the compartment 9 which is closest to the edge bearing the arm 11.
After the completion of this second compartment, 9, the movable bottom 1 is placed horizontally in a higher intermediate position, represented shown in Figure 3. In this superior position between

9 medium, the mobile bottom 1 is substantially at the level of the surface 4 of the water 6, and its arm 11 extends under the three steps 12, 13 and 14 to lock them in position high.
Because they are distinct, the compartments can be filled with air one after the other so to simplify the management of the rise of the mobile fund tilting it gradually, which allows in particular to prevent him from turning back abruptly.
Once the moving floor has reached the position upper intermediate of Figure 3, the system is ordered to fill with air its central compartment 7, in order to make the mobile bottom up again high above the surface 4 of the water 6, so that he would ringwidth a so-called upper upper position corresponding to that of Figure 4.
Once this top upper position has been reached, the system is controlled to block the bottom mobile 1 bears on the upper edges of the basin 3.
For this purpose, the mobile bottom 1 is provided with organs blocked around its periphery, and which for example in the form of bars 17 and 18, telescopically movable to deploy horizontally in order to exceed the contour of the moving bottom 1, that is to say say beyond the outline of the basin 3 seen from above.
As illustrated in Figure 4, when the organs 17 and 18 still known as support hands are de-folded, they extend above the lateral edges 19 and 21 of the basin 3.
Once these organs 17 and 18 have been ordered to deploy, the system is piloted to evacuate the air contained in all its compartments. The mobile bottom 1 down again from a certain height to resting on the edges 19 and 21 of the basin 3 thanks to its locking means 17 and 18 deployed which then engage 5 in corresponding housings made in the edges 19 and 21.
At this stage, which corresponds to FIG.
is placed at its final upper position that is to say it is at ground level surrounding basin 3, and that

10 its arm 11 holds the moving steps 12, 13 and 14 blocked at this height. The mobile bottom then being maintained by its blocking devices, the presence of water in the pelvis is not necessary for its maintenance.
Moving the movable bottom 1 from its position upper end of Figure 5, up to the Figure 1 is assured by first ordering the system to introduce air into the different compartments so as to make it significantly above the surface 4 of the water 6.
The locking members 17 and 18 can then be ordered to retract. The air can then be evacuated of the central compartment 7, before evacuating the air from the lateral part 9, which has the effect of provoking descent of the mobile bottom in an inclined position, as in the case of Figure 2.
At this point, the air can be removed from the compartment 8, and compartments of the steps 12, 13 and 14, which allows to place the mobile bottom 1 horizontally at the bottom basin 3, while configuring the movable steps 12, 13 and 14 steps 16, which corresponds to the situation of Figure 1.

11 Starting from the situation in Figure 5, it is also It is also possible to raise the mobile bottom 1 in po-top upper layer to retract its organs from blocking, but only to bring it back down partially, to place it in a horizontal position intermediate zone, to reduce the depth of the sin 3, for example, so that children can enjoy risk free.
In this case, the mobile bottom 1 can advantageously be retained at intermediate height by means of each having an end attached to an edge of the base sin and another end attached to the moving bottom, as schematically illustrated in Figure 6 in which these straps are marked with 22 and 23.
Complementarily, or alternatively, to these straps, the movable floor may be provided with Adjustable brackets of low height, deployable, and to stabilize the bottom at an intermediate height diary.
The movable bottom 1 according to the invention is advantageously designed to support one adult per meter square, while having a relatively general structure lightly.
For this purpose, and as illustrated schematically in FIG. 7, the movable floor according to the invention comprises a general structure consisting of beams 24, assembled with joists 26 and possibly joists 27 to form a carrier base on which is reported a dressing not shown.
This covering or coating may be in wooden slats, in the form of tiles or

12 be, and it advantageously has gaps for allow a large circulation of water cilitate the movements of the moving bottom between its position upper and lower position.
Beams, joists and joists, as well as the elements 28 constituting the arm 11 blocking steps of the staircase are advantageously profiled pultruded fiberglass, which has multiple advantages for such a mobile background. In particular, such material is incorrodible, strong, light, insensitive to chlorinated products and electrolysis.
The locking members such as the member 17 can be controlled centrally, manually or well automatically, via a rotating bar 29 extends perpendicular to these organs, in the plane of the body of the mobile bottom.
Each sliding bar of a locking member is then recalled to a position deployed by a spring not shown, and it has an integral end connected to a cable 31 wound on this rotating bar 29. A rotation of the bar then causes the locking devices, while the release of this rotating bar causes the exit of these organizations under the effect of their return springs.
In order to make the maintenance of the mobile bottom safer, for example for long winter periods, this one can still be equipped with retractable lower legs, such as the feet 32. These feet 32 can present themselves in the form of electric or pneumatic cylinders, and can can be deployed in a user-controlled manner

13 once the moving floor has reached its top position final version.
The number of feet can be planned so that appears from the mobile bottom to be capable of supporting one or more vehicles parking on the mobile bottom in high position.
It is also possible to provide an arrangement in which the retractable feet 32 replace the blocking hands 17 and 18 instead of completing them. In this case, the retractable legs are deployed when the movable bottom is in the upper upper position of the figure 5, before emptying the air compartments to bring the mobile bottom to its final upper position.
The mobile bottom according to the invention can advantageously be equipped with different complementary elements protruding from its outer periphery. These elements can be in the form of a hose 33 which runs along the beams and beams of the edges of the movable bottom. This flexible pipe 33 is then maintained at a short distance beams it carries, for example by elastic means ticks such as springs, so as to guide the bottom mobile during its ascent along the internal faces of the basin, and so as to dampen any shocks of this mobile bottom against the walls of the basin.
Similarly, a circulation of water can be established in the mobile bottom so as to constitute jets 34 ejecting water laterally to the horizon-tale, beyond the contour of the movable bottom so as to guide and / or cushion any shocks of the moving floor against the walls of the basin.
This circumference can still be equipped with brushes 36 extending horizontally so that their hairs de-

14 outline, such a brush having also for effect of guiding the moving bottom during its ascent, but also prevent objects from falling between the mobile bottom and the edge of the basin.
Each profile used to form a beam 24 or a beam 26 advantageously has a sec-cross-section defining two distinct compartments ts, as shown in FIG. 8. Such a profile comprises in cross-section, a first portion 37 open and intended to constitute a technical sheath by receiving for example the air supply tubes and other ac-as well as electrical cables, and a closed procedure 38 for the establishment of to receive air and / or water to move vertically moving bottom by flotation.
As illustrated schematically in Figure 8, the open portion 37 of the section of the profile forming a sheath while the closed portion is located low tie. The upper open portion 37 is closed either by a specific cover or directly by the upper covering of the movable bottom according to the invention.
Moreover, these beams and beams are obstructed at their ends to easily form compartments able to receive air and water.
The profile section shown in FIG.
corresponds to the beams and beams constituting the structure of the movable bottom body, can also be used designed to form side rails for mounting movable steps for mounting these sliding steps vertically by guiding their movements.

Concretely, these same profiles can be fixed vertically to the walls of the pool basin in the region of its access staircase, in pairs being face each to constitute a system for guiding 5 both ends of a sliding step vertically.
Such an arrangement is shown in FIG.
three pairs of vertical rails have been respectively 12a and 12b, 13a and 13b, and 14a and 14b, these pairs of rails being intended to re-10 see steps 12, 13 and 14 respectively presented in Figure 9.
As illustrated in Figure 9, the two rails of each that pair are positioned in such a way that their open portions face each other so as to delimit each

15 a guide section in which can be engaged a walking end having a complementary shape to hush up. The closed portions of each of these rails of-frent to these a sufficient mechanical rigidity for that they can offer an appro-requested in all circumstances.
In general, the mobile bottom according to the vention can remain safe and without water, as well in the lower position than in the upper position termédiaire. It is advantageously equipped with a hatch access made in the coating, between two beams or beams so as to allow the introduction of a cleaning robot in the basin when this moving bottom is in the upper position.
As can be understood, the moving bottom according to the invention can be installed in a pond regardless of

16 coating of this basin which can be a membrane of type liner, raw concrete, tile or other.
The mobile bottom according to the invention can also have a bench or stairs provided fixed or movable relative to the movable bottom body.
