Definitions

  • the technical field of the invention is that of buildings or similar constructions intended for a particular use such as swimming pools or wading pools, and more particularly to a movable bottom device of such a construction.
  • the device below aims to remedy all or part of the aforementioned drawbacks and / or in particular to achieve a simple, reliable and economical mobile pool bottom or paddling pool.
  • Said movable pool floor is characterized in that it comprises, for each cable, at least one said coach, a said trainer driving at most one said cable, and in that the trainers are attached to the pool or ground mobile, the traction means then being arranged so that the lengths of the cables between the trainers and respectively the movable floor and the pool are substantially equal to each other.
  • such an arrangement of the traction means ensures a distribution of substantially equal forces between the trainers. This makes it possible in particular to be able to reduce the useful traction forces of the trainers, which can then have a lower power and consume less energy.
  • these so-called means of catching length also ensure a distribution of substantially equal forces between the trainers. This allows, in particular, as mentioned above, to be able to reduce the useful traction forces of the trainers, which can then have a lower power and consume less energy. This is particularly advantageous when the mobile floor is rigid and not articulated, said movable floor being kept horizontal.
  • the movable bottom comprises, for each cable, at most a cable return.
  • the limitation of the number of cable returns to a cable element limits the length of the cables.
  • the traction means are able to create a force of which a principal component is directed upwards.
  • each of the trainers is attached to the pool.
  • each of these said trainers causes the cable through the second end so as to form a cable pool.
  • the driver rotates a single shaft, which is attached to said second cable end, the cable pool being formed by the cable portion wrapped around the shaft.
  • Each of the first ends of the cables being in turn advantageously connected to the movable ground by a fastening located on the periphery of the moving ground, this makes it possible, on the one hand, to improve the stability of the moving ground during its movement and, on the other hand , improve the effectiveness of the action of the coach.
  • the coach substantially level with or immediately near this beach of the pool, is then able to wind and unwind the cable. Therefore, the provision of multiple traction means on the periphery of the pool allows, through the action of the trainers, to create tensile forces on the cables and thus to mount the mobile floor. Conversely, when the trainers reverse this traction force, it allows the descent of the moving ground.
  • the coach whether motorized or manual, must overcome a force of inertia at startup due to the weight of the moving ground.
  • the mobile ground may comprise flotation means making it possible to partially relieve the effect of the weight of said moving ground and thus to overcome this starting inertia.
  • this makes it possible to use low voltage motors compatible with a solar energy supply, and, in the case of a manual trainer, to relieve the effort required, for example in the rotating a crank.
  • the cable return is in this variant preferably a pulley located on the edge of the pool.
  • this cable return is able to change the direction of the cable between the mobile floor, particularly at its periphery, and the pool, particularly the coach, where are fixed respectively the first and second end of said cable. In this way, the angle formed by the edge of the pool does not affect the effectiveness of the trainer.
  • the mobile floor is able to float in a free state, and the traction means of said mobile floor are, in a biased state of said moving ground by these traction means, able to exert a force F T on the mobile ground with a principal component F TX directed towards the fixed bottom.
  • the mobile ground is able to float on the water if no traction force is exerted on it.
  • the mobile ground in the case where a tensile force is exerted, the mobile ground is able to be placed in a position of equilibrium, below the floating level in the free state, equilibrium position then defined as a state flotation in the stressed state.
  • the buoyancy and the weight being constants to the same system, only the variation of the tensile force is able to place the moving ground in this stressed state.
  • the trainer by the action of the trainer on the cable, it is able to create a tension on the latter exerting a tensile force on the mobile ground, effort directed downwards, which will have the consequence to descend the moving ground and to place it in the requested state of flotation. It is the relaxation of the voltage on the cable that will allow the mobile ground to rise.
  • the action of the trainer is to vary the length of cable to change the depth of the moving ground.
  • said mobile floor comprises a plate and flotation means.
  • the flotation means are chosen in particular according to the size of the pool, the coating of the upper plate, and the volume of gas necessary for its flotation.
  • each of the trainers is fixed to the plate and drives the cable through the first end so as to form a reserve of cable .
  • the action of the trainer is to vary the length of cable for changing the depth of said moving ground.
  • each of the second ends of cables is connected to the pool by a fastener located on one of the erected walls.
  • the mobile floor having vertically at least one thickness, each of the fasteners connecting the second ends of the cables to the pool is located at a maximum distance from the fixed bottom equal to the largest thickness of the moving ground.
  • the cable return is in this second option preferably a pulley located on the edge of the plate.
  • this cable return is able to change the direction of the cable between the mobile floor, particularly at its periphery, and the pool, in particular the coach, where are fixed respectively the first and second ends of said cable.
  • the angle formed by the shelf edge does not affect the effectiveness of the coach.
  • These guide means may be rollers arranged between the walls erected laterally and the movable floor.
  • the locking means may be cylinders located at the periphery of the moving ground and coming into contact with said upstanding side walls thus locking the moving ground to a certain depth.
  • the invention also relates to a swimming pool characterized in that it comprises a mobile bottom device as shown.
  • said mobile floor may be able to withstand in floating an overload of 150 Kg / m 2 , and whatever the force applied to the moving ground by the traction means.
  • the technical elements mentioned in this description are technical elements whose maintenance is particularly easy, which allows to dispense with any nearby technical room.
  • the reduced volume of said mobile bottom device allows to implement it on new pools but also on existing pools without requiring significant changes in the outdoor area. It does not matter also the shape of the pool.
  • the multiplicity of traction means also makes it possible to limit the effort made by the trainer, thus to respond to the environmental problem: the use of low voltage motors can be envisaged hence a possibility of using a source of solar energy.
  • the device comprises photovoltaic panels so as to supply each of the solar energy trainers, the latter advantageously comprising 12V motors.
  • the figure 1 shows a diagram of a movable bottom device 1 of a swimming pool according to one embodiment of the invention.
  • the pool shown has a fixed bottom 2 and laterally erected walls 3.
  • the movable bottom device 1 comprises a movable floor 4 adapted to be guided vertically uphill as descending through guiding means 11. It is understood that the vertical is defined as a reference axis substantially perpendicular to the movable ground 4.
  • the guide means 11 are here rollers attached laterally to the movable floor 4, that is to say between the mobile floor 4 and the erected side walls 3.
  • Each traction means 5 comprises a trainer 6 and a cable 7 whose first end 9 is fixed to the mobile ground 4 and whose second end 10 is fixed to the swimming pool.
  • the described swimming pool is equipped with six traction means and has a useful depth of 1500mm.
  • the six traction means are distributed on each side of the pool along its length and spaced substantially evenly favoring the distribution of forces for each cable.
  • each of the six trainers 6 is capable of driving a single cable 7, each of the trainers 6 being attached to the pool and driving the cable 7 by the second end 10 so as to form a cable reserve 7.
  • the side walls 3 are connected, at an upper end 3 ', externally to a substantially horizontal upper surface 12 and each of the trainers 6 is located substantially level with the upper surface 12 of the pool.
  • a pulley, single cable return 8 disposed in each of the traction means is located at the upper edge of the pool, more precisely at the upper end 3 'of the side walls 3, so that the cable 7 of each trainer 6 is as vertical as possible at its first end 9 and, therefore, improve the efficiency of the trainer.
  • the traction means 5 are here arranged so that the lengths of the cables between the drivers 6 and the mobile floor 4 are substantially equal to each other. Indeed, the traction means 5 are arranged so that the cables maintain an equal distance between the trainers 6 and the movable floor 4, even if a traction means comprises a reserve cable more important than another.
  • the movable bottom device 1 may comprise, in addition to or without the arrangement of the traction means 5, catch-up means of length so that that the respective lengths of the cables 7 between the cable returns 8, attached to the pool, and the mobile floor 4, connected to the traction means by the first ends 9 of the cables 7, are substantially equal to each other.
  • the means of catching length (not shown in the figures) comprise at least one set sensor (s) -coder (s), each of said sets being associated with a traction means 5 and connected to the same controller management ..
  • the encoder transmits information to the management controller, said information being measured by the sensor, which then determines the position of the moving ground 4.
  • a mobile ground control user 4 via the management controller, to descend to its maximum position, the controller to which it has programmed a number of pulses per trainer 6 necessary for the displacement of each cable 7, defining a certain duration of unwinding, then controls said trainers 6 to unroll the cables 7.
  • the management machine will take account of it for the next immersion of the mobile floor in the pool but for all the trainers 6, the lengthening of the cables 7 will have been totally corrected.
  • the trainers 6 are low voltage motors, in order to be able to use solar energy thus responding to the environmental problem. More generally, the entire mobile bottom device 1 is here supplied with electricity, precisely 12 volts, so that it can be powered completely autonomously by one or more photovoltaic panels.
  • the movable bottom device further comprises electro-brakes installed on the motors for stabilizing the mobile floor 4 at the desired location of use. Said electrobrakes are thus capable of braking or even blocking the ascent or descent of the mobile ground 4. The latter makes it possible to locking the trainer 6 which blocks the rise or fall of the mobile floor 4 outside the movements of up or down. Said mobile floor 4 is thus suspended. In the case where the mobile floor 4 is locked in its highest position, cylinders positioned on the edge of the pool advance rods which are inserted into the movable floor 4 including openings provided for this purpose and permanently blocks the mobile floor 4 in the high position.
  • the elongation of the cables 7 may not be greater than 1% of the useful depth of the pool, or 15mm of elongation, in time.
  • the rods controlled by the jacks are cut to a point so as to be able to penetrate into the openings located laterally on the mobile floor 4 and to be able to lock it so as to a game of plus or minus 12mm.
  • the power of the cylinders is large enough to force the penetration of the rods into said openings and thus "replace" the mobile floor 4 in the correct position.
  • a maintenance operation possible remotely via the Internet in the case where the management controller is connected via this network, allows in the case where the controller has failed in his job, to tighten the cables 7 without descending the mobile floor 4 : said maintenance operation of engaging the cylinders, start engines 6 one by one to reposition the plate 13 and catch the strokes of the cables 7.
  • the combined use of the locking means 15 which are the cylinders and rods and the lift of the cables 7, allows the mobile floor to have an operating overload of 250 kg / m 2 out of the water. Archimedes thrust allows when the mobile floor 4 is immersed to retain more than 150kg / m 2 of overload per square meter.
  • the figure 2 shows a diagram of a movable bottom device 1 of a pool according to this same first embodiment, in top view for a pool of rectangular section and whose movable floor 4 is adapted to this form.
  • the figure 3 shows a diagram of a floating bottom device 1, called "floating" for swimming pool according to a second particular embodiment.
  • a pool built here in masonry, more precisely comprises a fixed bottom 2 and side walls erect 3.
  • a movable floor 4 Disposed on the surface of the water is positioned a movable floor 4 having a plate 13 and 14 float means distributed regularly below said plate 13 and integral with each other.
  • These flotation means 14 are here floats filled with a volume of air calculated according to parameters such as the size of the pool and the coating of the plate 13 so as to ensure optimum flotation of said movable floor 4.
  • the coating this plate 13 may be for example tile or wood.
  • the trainers 6, here low voltage motors, here forming an integral part of the plate 13 allow, in this embodiment, to come and fix the first ends 9 of the cables. Therefore, each motor has a cable reserve and is able to unroll and wind said cable 7 around a motor axis. These engines are powered by 12 volts.
  • the traction means 5 each comprise a driver 6 and a cable 7, a first end 9 is fixed to the movable floor 4, more precisely and preferably to the plate 13, and a second end 10 is fixed to the pool.
  • the traction means 5 are here arranged so that the lengths of the cables 7 between the trainers 6 and the pool are substantially equal to each other. Indeed, the traction means 5 are arranged so that the cables 7 maintain an equal distance between the trainers 6 and the pool, even if a traction means comprises a reserve cable 7 greater than another.
  • a cable return 8 is disposed between the first 9 and second 10 ends, here at the periphery of the plate 13 so that it is adapted to serve as an application point P of the force F T.
  • the main component F TX is vertical. It is pointing down.
  • Guiding means make it possible to reduce the friction between the mobile ground 4 and the lateral walls 3 that can be induced by the existence of a horizontal component F TY of the forces applied to the moving ground 4.
  • the results obtained are such that the mobile floor 4 is able to withstand in floating an overload of 150kg / m 2 .
  • the mobile soil structure 4 is made in such a way that the Archimedes thrust is sufficient to naturally raise the plate 13 to the surface of the water, for example by setting up an air reserve, here the floats 14 .
  • locking means 11 of said mobile floor vis-à-vis said side walls 3 are located at the periphery of said movable floor 4.
  • cylinders are arranged such that they are able to come into contact with one of said erect walls 3.
  • Racks can be arranged vertically on the side walls 3 of the pool, directly above each motor 6, for guiding the movable floor 4, these racks can be toothed right or inclined or blocking the mobile floor 4 to a chosen depth.
  • the figure 4 shows another detailed diagram of a moving bottom device 1 floating pool for this same second embodiment.
  • the general shapes of the mobile floor or the pool may be different.
  • the shape of the pool is free and allows the device as described to adapt to any form of pool, new or existing.
  • coaches can be associated with a cable, thus providing for a main trainer and an emergency trainer in case of technical damage.
