Definitions

• the present invention relates to a movable bottom device for a basin filled with water, such as a pleasure pool or any other work in which it is desired to cover the surface of the water with a removable floor.
• the technical field is the construction of floors or covering devices consisting of rigid elements for basins such as swimming pools.
• the security is not complete due to the deformability of the curtains and it is not possible to walk normally and several people on them; insulation is limited because you can not have too thick blades that would interfere with storage and handling; and when they are not used, the rolled curtains, even of small thickness, represent bulky volumes which occupy a part of the beach surrounding the basins,
• a fourth type of equipment on the concept of the third above in the immersible version, proposes to replace the mechanical lift system with ballasts integrated in the movable floor, as described in the patent application FR 2 945 063: however, the total height of the floor-ballast structure is then very thick, which reduces the useful depth basins when they are placed at the bottom (or increase the initial depth of the basin); moreover, the difficulty of controlling the quantity of air injected into the ballast compartments renders their stability and their horizontal maintenance uncertain, requiring complex control and guidance devices; and these devices include flexible supply systems and lines for supplying and distributing the air inside the ballast compartments, which complicates the construction and installation.
• the problem posed is then, in the context of the concept of immersible and ballasted floors, to reduce the total height of the structure carrying these floors, to increase their stability during the phases of emergence by air injection and immersion by drain of this air, and allow a simple manufacture and installation.
• a solution to the problem posed is a movable bottom device for a basin filled with water according to the general concept defined above, namely having a structure carrying a floor at least partially matching the shape of the basin surface and supported by at least one ballast, which ballast is capable of moving the device between at least one immersed position in which the device rests on the bottom of the basin and a position in which said floor has emerged and covers at least said part of the surface of the water :
• the at least one ballast is open skirt-shaped at its lower part and the device comprises at least one air inlet mouth disposed at the bottom of the basin and vertically to the opening of the skirt of the ballast, which skirt is preferably flexible and able to bend when the device rests on the bottom of the basin.
• the device according to the invention comprises at least two independent ballasts and at least two air intake vents, and each ballast comprises a discharge valve of the air at the top.
• ballasts can reduce the height of the structure, although, of course, it is necessary that the volume of such ballasts, especially when it comes to a flexible skirt that folds so when the structure is placed on the bottom of the basin, must allow to fill them enough air to lift the assembly from this position; and as the structure rises to the surface, the skirts, when they are flexible, unfold, and the lifting thrust and stability increase.
• the installation of air inlet vents on the bottom of the basin avoids any connection and supply, such as flexible, mobile bottom: installation and implementation of it are thus simplified .
• Figure 1 is a sectional view of a basin filled with water and wherein a movable bottom device according to the invention is arranged at rest on the bottom of the basin.
• Figure 2 is a sectional view as in Figure 1 with the movable bottom being ascended to the basin surface.
• Figure 3 shows the same basin and the same movable bottom structure as in the previous figures, but in the surface position.
• Figure 4 is a partial view of Figure 2 explaining some guide elements.
• Figure 5 is a partial sectional view of Figure 2 explaining the stability of the device.
• the movable bottom device 19 for basin 10 filled with water 8 comprises a structure 11 carrying a floor 1 at least partially matching the shape of the basin surface and supported by at least one ballast 2, which ballast being able to move the device 19 between at least one submerged position in which the device rests on the bottom 21 of the basin, as shown in FIG. 1, and a position in which said floor 1 has emerged and covers at least said portion of the surface 9 of the water, as shown in FIG. 3, knowing that, in the accompanying figures, the floor in fact marries the whole of the basin surface and in other embodiments for which safety is not necessary for the entire surface, it could cover only part of it.
• the at least ballast 2 is in the form of a skirt 12 open at its bottom and the device comprises at least one air inlet mouth 3 disposed at the bottom 21 of the basin and at the vertical of the opening of the skirt of the ballast 2.
• the device comprises at least two independent ballasts 2 and at least two air intake ports 3, as shown in the figures which are vertical sectional views in one of the dimensions of the basin, and this distribution can also be reproduced in the dimension perpendicular to that shown, the device then comprising at least four independent ballasts arranged in a square or rectangle; and if the basin is longer than wide, three rows of two ballasts may be arranged lengthwise; and to have an even greater stability for tanks of large dimensions, it can be arranged three rows of three ballasts etc., knowing that then it takes at least one air inlet mouth 3 below each ballast .
• the air intake vents 3 can be simply placed on the bottom of the pool and fed by air ducts 4 which can either be easily placed along the bottom of the pool for the existing basins, or integrated into them. for basins under construction, up to a technical room 7 built possibly far enough from the basin to clear the beaches surrounding it, which technical room contains at least one air pump 6 which feeds said lines 4 through regulating valves 5.
• the skirt 12 of the ballasts is flexible and able to bend when the device rests on the bottom 21 of the basin, as shown in Figure 1 and these skirts 12 each comprise at least one ballast 15 disposed around their lower opening, either continuously or discontinuously; which ballast 15 is able to keep unfolded the skirt 12 when the device 19 is lifted from the bottom, as shown in Figures 2 and 3.
• These weighted skirts also prevent or at least reduce air loss if there is inclination (pitch or roll) of the structure, as shown in Figure 5; this figure also illustrates the stability that allows the provision of several independent ballasts and variable air volume 20, side by side.
• each ballast 2 comprises a valve 13 for evacuation of air at its upper part, as shown in FIG. FIG. 2.
• the skirt 12i of the first one will inflate further. that the skirt 12 2 of the second and the air content 20i in the ballast 2i will evacuate faster than in the other ballast 2 2 and gradually restore the balance between the different ballasts with a better distribution of air.
• the valves 13 can be controlled closing and opening, but this would complicate the installation and implementation.
• the movable bottom device 19 comprises rollers 16, 17 of lateral guide integral with the structure 11 and able to bear against the vertical walls 22 of the basin 10, as shown in FIG. 4.
• rollers 16 are fixed at the level of the structure close to the floor 1, others 17 are carried by articulated support arms 18 which unfold when the device is lifted from the bottom and which make it possible to prevent the all of the movable bottom device 19 can be tilted too much, the time that the self-balancing system of the air in the ballasts by the valves 13 can ensure the maintenance of the structure the more horizontal possible.
• movable latches 14 are able to be open at the periphery of the carrier structure 11 and thus to join it with the vertical side walls 22 of the basin, when the movable bottom device 19 has arrived in floating high position at the surface 9 of water 8 of basin 10; the device is then supported and supported by these latches 14, the air inlet can be stopped, and the floor can receive people safely.
• the present device according to the invention is thus such that it enables the surface of a basin 10 filled with water 8 to be covered by the mobile bottom device 19, as previously described, and such that:
• At least one air inlet mouth 3 is provided at the bottom 21 of the basin 10 and said support structure 11 rests on this bottom 21, the bell-shaped ballast 2 is made to open downwards and this opening is placed above the air intake opening 3,
• ballast 2 preferably at least two independent ballasts are provided on the carrier structure 11 and at least two air vents on the bottom of the tank 21, air is let out at the top of each ballast 2 by a valve 13
• the structure 11 is immobilized and laterally locked by means of movable latches 14 able to open on the periphery of the carrier structure 11 and thus to secure it with the side walls 22 of the basin,
