The present application is based on, and claims priority from, France Application Number 04 01634 filed Feb. 18, 2004, France Application Number 04 03622 filed Apr. 6, 2004 and PCT/FR2005/000351 filed Feb. 16, 2005, the disclosures of which are hereby incorporated by reference herein in their entirety.
The present invention relates to a profile for assisting in the construction of a floor for a pool, the profile including at least one internal cavity crossing it longitudinally and which is intended to be used as ballast, the profile presenting a first end and a second end sealed respectively by a first end piece and a second end piece provided with connection means through which the profile can be filled or emptied.
Such a floor, commonly known as a floating floor, is intended to cover the surface of the water contained in a swimming pool, in periods of non-use, chiefly in order to prevent risks of drowning and reduce the heat loss of the water with respect to the exterior and which can be immersed to enable the normal use of said swimming pool.
Such a floor is constituted by, for example, hollow profiles manufactured from plastic and joined laterally and which are filled with water to immerse it or filled with air to cause it to rise. The ends of a single side of the profiles are connected to each other by means of a manifold that is itself connected to a first pipe linked to a pump of the suction/pressure type of a water filtering unit of the swimming pool. This pump is connected to a second pipe, the free end of which is immersed in the water of the swimming pool.
The ends of the profiles located on the opposite side are connected to each other by means of another manifold that is itself connected to a third pipe, the free end of which is located above the level of the water.
To immerse the floor at the surface of the water, the pump is switched on in a first position called suction in which it sucks up the water contained in the swimming pool and forces it into the profiles, which then fill up. The water gradually fills the profiles during this operation.
It may happen that during this operation, the water introduced into the profiles, seeking to occupy a volume located at the lowest point, moves to the same side of the profiles, with the result that one end of the profiles sinks first whereas the other end rises in reaction and comes out of the water, which causes the floor to tip up. This situation can prove to be delicate as the emerged end of the floor generally slides on an edge of the swimming pool and the floor does not lower correctly.
Hence, the aim of this invention is therefore to propose in particular a profile for a floating floor of a pool such as a swimming pool, the profile being designed so that the floating floor can move in parallel to the surface of the liquid during the immersion and emersion operation of the said floor.
To this effect, a profile is proposed that is designed for the construction of a floor for a pool, and that can float or be immersed, the profile being provided with at least one internal cavity crossing it longitudinally and which is intended to be used as ballast, the profile presenting a first end and a second end sealed respectively by a first end piece and a second end piece provided with connection means through which the internal cavity can be filled or emptied, the said profile being noteworthy in that the connection means are connected respectively to two channels opening out, for the one, into the upper section of the internal cavity and, for the other, into the lower section of the internal cavity.
The water allowed into the profile enters the profile from its lower section and the expulsed air leaves by its upper section, with the result that it can be almost completely filled with water before another profile connected further on can begin to be filled.
Conversely, when emptying the profile, the water is evacuated through its lower section, with the result that it can be emptied almost completely of its water as soon as the other profile is emptied and that it only lets air enter the said profile.
A floating floor constructed with such profiles thus moves while maintaining a horizontal level during its immersion or emersion movement in the pool.
According to an additional characteristic of the invention, and in a first embodiment variant, the profile comprises internally an upper conduit and a lower conduit arranged on either side of the internal cavity, which are connected respectively to the said internal cavity by passages, the channels being connected respectively to the upper and lower conduits.
The profile is also fully filled and emptied, even in the case in which it is placed in an inclined position, as for example when it is lying on an inclined pool floor.
Advantageously, a first and a second separating wall delimit the two upper and lower conduits and the internal cavity, one end of the first wall covering one edge of a base of the first end piece, another end of the first wall being arranged offset from the edge of a base of the second end piece to create one of the passages, the second separating wall being offset in the reverse direction of the first.
Such a profile is realized simply by shortening the separating walls.
According to one additional characteristic of the invention, the profile comprises an articulated link enabling it to be assembled in an articulated manner with another profile arranged laterally for, for example, to follow a change of slope in the floor of the pool.
Advantageously, the articulated link is constituted by a tongue and a groove arranged respectively on the lateral sides of each profile.
According to an additional characteristic of the invention, the profile comprises rims on either side of its lower wall, forming a stop to limit the angular motion when closed with another profile arranged laterally.
According to an additional characteristic of the invention, the groove and the rims are realized discontinuously on each profile to create a plurality of places of water passage, to be able to accelerate the immersion and emersion movements of the floating floor.
This may be a straight type connector to connect the profile with another profile located in its extension or a connector of the elbow type to connect the profile with another profile located laterally. Each connector is preferably fixed by gluing in a housing opening in the front wall of each end piece.
According to an additional characteristic of the invention, the profile is provided with an articulated junction capable of assembling two profiles arranged in line with each other from a mechanical point of view and in an articulated manner.
Advantageously, the articulated junction comprises a first sleeve and a second sleeve mounted respectively on shaped supports protruding from the end pieces.
According to an additional characteristic of the invention, the first and second sleeves are constituted by a section of a profile cut in two parts along its median plane, the sleeves being coupled by the articulated link and their lateral walls being drilled with holes to allow for the passage of a connecting pipe between the connection means.
According to an additional characteristic of the invention, an inclination device is fitted between the first and second sleeves to increase, according to a particular value, the angle of opening of two profiles arranged in line with each other.
According to an additional characteristic of the invention in a second embodiment variant, the profile comprises a plurality of internal cavities arranged side by side and such that each specific end piece that seals each of its ends is provided with connection means opening respectively into the internal cavities.
The largest width of this profile allows the floating floor to be fitted more rapidly.
According to a an additional characteristic of the invention, the profile is provided, in a third embodiment variant, with a third conduit arranged between the upper conduit and an upper wall of the profile, the third conduit being provided to enable water to circulate to heat it under the effect of solar radiation, each end piece being provided with an additional connection connecting with a channel opening out into the third conduit.
Advantageously, one of the end pieces of this profile is provided with a wall delimiting one side of the channel and that is extended by an edge penetrating the third conduit.
According to an additional characteristic of the invention, the connection means through which the profile can be filled or emptied or the additional connection is via an offset connector.
A floor for a pool, capable of floating or being immersed, the floor comprising profiles as described above is also covered by the present invention.
According to a characteristic of this floor, it is constituted by several groups of rows of profiles and for a single group, the rows are connected one after the other so as to give priority to a filling of the rows located closest to the edge of the floating floor.
According to an additional characteristic of the invention, the floor is provided with a protective belt bordering its edge, the protective belts incorporating a flexible pipe.
According to an additional characteristic of the invention, the groups are connected, on the one hand, to a filling an emptying manifold designed to be connected to a pump of the suction/pressure type and, on the other, to a vent manifold.
According to an additional characteristic of the invention, a manifold for feeding and purging a water heating circuit is connected in parallel to the filling and draining manifold.
According to an additional characteristic of the invention, another vent manifold is connected in parallel to the vent manifold to separate the water heating circuit of the floating floor from its ballast circuit.

The floating floor that is described in this invention is designed to be able to float on the surface of a liquid contained in a pool such as a swimming pool to prevent humans or animals from drowning or to support any objects that may fall into the said pool. The floating floor of the invention can also be immersed so as to lay on the bottom of the pool to allow normal use.
In the following description of the floating floor of the invention, only the application as a swimming pool cover is described.
The floating floor 100 covering a swimming pool shown in
In
Each profile 200 preferably has a rectangular cross-section. It will preferably be manufactured in a plastic material by an extrusion process. Its density is greater than that of water, that is its density is greater than one.
Each profile 200 comprises an articulated link 210 enabling it to be assembled in an articulated manner with another profile arranged laterally.
The articulated link 210 is constituted advantageously by a tongue 212 and a groove 214 arranged respectively on the lateral sides of each profile 200 and near its upper wall 204, namely the wall that is normally intended to face upwards and which are formed so as to cooperate one with each other to mutually assemble two profiles 200 in an articulated manner when they are arranged one against the other on one of their sides, as shown in
The opening provided on the groove 214 enables the two profiles 200 to be assembled when they are tilted laterally with respect to each other at an angle of approximately 60°, as the arrow F1 shows in
The angular motion of the two profiles 200 assembled to each other can oscillate in a range of angles between 00 and 30°, as shown in

The connection means 270 is constituted, for example as shown in

Hence, when the profile 200 is being filled, water enters the profile from the lower section and the expulsed air leaves by the upper section, with the-result that it can be almost completely filled with water before another profile connected further along can begin to be filled.
Conversely, when emptying the profile 200, the water is sucked out through the lower part, with the result that it can be emptied almost completely of its water as soon as the other profile is emptied and that it only lets air into the said profile.
In
This remark is also valid for the profiles that are among the last to be filled that still remain floating whilst the floating floor is resting at the bottom.
On emptying, the suction point in the profile 200′ is positioned at the lowest point, with the result that it can be almost completely emptied.

It will be noted in
When the withdrawal is the shortest (distance Li), the separating wall 224, 226 can cover an edge of the base 274, as shown in the bottom right-hand area of
When the offset is the longest (distance L2), the separating wall 224, 226 does not cover the said edge of the base 274, as shown in the top right-hand area of
The same separating wall 224, 226 has a short offset (distance LI) and a long offset (distance L2) according to one or other of the relevant ends of the profile 200′. At the same end of the profile 200′, the values of the offsets (Li, L2) of the separating walls 224 and 226 are different.
It will be noted in this
The end piece 250 through which the water is admitted into the profile 200′ is shaped so that its channel 272 can open directly into the lower conduit 222, which also corresponds to the position of the end piece 250 located on the right of
If the floating floor is required to cover a sloping floor in its immersed position, it will be ensured that the different profiles entering into its constitution are assembled by placing their passages 228 so that they are situated in the highest part of the said profiles when they are lying on the floor of the swimming pool.
During its emptying operation, the air entering the profile 200′ enters the profile by the upper section and the expulsed water leaves by the lower section, with the result that it can be almost entirely emptied before another profile connected further up can be emptied in its turn and even though the profile can be positioned in a non-horizontal manner.
The filling of the different rows of profiles used in the construction of a floating floor can therefore be controlled in this manner. To illustrate this purpose,
It will be noted that a row can be constituted by one or more profiles according to the dimensions of the swimming pool to be covered or the standard length of each profile. In
The ends of the profile 200′ shown in

The articulated junction 300 comprises a first sleeve 310 and a second sleeve 320 assembled respectively on the two pairs of supports 280 of the flanges of the two end pieces 250 sealing the facing ends of the two profiles. The sleeves 310 or 320 are each advantageously constituted by a section of a profile 200, 200′ that has been cut into two sections along its median plane and by placing the two parts back-to-back. Their lateral walls are drilled with holes for the passage of a pipe 340.
Each sleeve 310 or 320 is fitted then assembled preferably by gluing on the two stubs 280 and possibly in the slots that they contain.
The cut length of the profile section is identical to its width so that the outer perimeter of the sleeves 310 and 320 is identical to that of a profile so as not to create any discontinuity of form in the junction area.
The articulation joining the two sleeves 310 and 320 of the articulated junction 300 is advantageously realized by a tongue 212 and its corresponding groove 214 coming from the section cut from a profile so as to allow an angular movement between two consecutive profiles at the level of their ends so that the floating floor can adapt to a swimming pool floor with multiple slopes. The angular motion of the two profiles is limited in one direction by the rims 230 present respectively on the first sleeve 310 and the second sleeve 320. When the rims 230 are in contact, the two profiles are arranged noticeably in alignment with each other.
The pipe 340, preferably a flexible pipe of the annular type, is mounted by its ends on the connections 270 of the two end pieces 250 to connect the two profiles from a hydraulic point of view.
The mounting of the tube 340 on the connectors 270 can be helped by bending the two profiles along their shared axis of articulation as shown by the arrow F2 in
To increase the angular motion between two consecutive profiles, for example, when the slope of the swimming pool floor is reversed, it is possible to remove the rims 230, for example by removing them through a cutting operation.
It is also possible, in
The inclination device 350 will be advantageously constituted by the two sides provided with their tongue and with their groove of a profile and which are removed, for example by cutting, then assembled back-to-back, for example by gluing. T1 sides are assembled on the sleeves 310 and 320 by means of their tongue 212 and their groove 214. Several inclination limiters 350 can be combined to increase the value of the angle of opening L of two profiles.
In
It will be noted that at least one pair of profiles connected in the same manner can be placed between the two profiles shown in
In
The floating floor is manufactured according to a plan that notably specifies the dimensions of the surface of the swimming pool to cover, the geometry of its floor. Most of the profiles constituting the floating floor are composed of profiles of a standard length. The profiles designed to be fitted at the end of a row are cut to length.
The various profiles 200, 200′ are then sealed by end pieces 250, then referenced. Each profile 200, 200′ fitted with its end pieces 250 is marked with a sign speci its direction of assembly. A set of instructions accompanies the batch of the various components comprising, among others, sections of pipes pre to length. The operator assembles the various rows of profiles, then places them on the surface of the water as they are completed.
Groups of rows G1 -G4 are constituted by connecting a set of profile rows 200, 200′ with ends of pre-cut tubes.
In
The filling and draining manifold 400 is connected to the filtering unit of the swimming pool by means of a bypass line D connecting the pressure circuit of the pump P on the one hand and the suction circuit on the other. Valves V are connected to the filtering unit to act on the water circulation in the floating floor 100.

The different valves shown can advantageously be replaced by a multiple-way valve or by solenoid valves.
The duration of operation of the pump is set, for example, by means of a timer.
In its floating position, the floating floor of the invention enables drowning hazards to be removed.
When immersed, it enables a person in difficulty in the pool to be brought to the surface.
It reduces bacterial activity due to the action of the light.
It also reduces the loss of heat as well the power consumption of water treatment products.
Through the multiple structure of the profiles constituting it, the floating floor cannot sink in the event that the upper wall of a profile is pierced.
During its movement, and in particular at each emersion operation, it can also lift off particles adhering to the walls and floor of the swimming pool to put them into suspension so that they can be captured by the filtering system of the swimming pool.
It can be delivered in kit form, thus offering a great ease of transport.
It can be assembled without it being necessary to empty the swimming pool.
The profiles can be manufactured in different colors, thus enabling swimming lanes to be delimited on the floors of swimming pools destined for use in competition.
As an illustration, the floating floor of the invention can be used to immerse or raise objects, for example, oysters in a settling tank, a boat in a dry dock, etc.
In a second embodiment variant of the profile that is shown in
A specific multiple type end piece 250′is shown in line with the profile 200″. It is designed to close off each of the extremities of the profile 200″. The end piece 250′is, for this purpose, provided with a plurality of connection means 270 that open out respectively into the internal cavities 202 of the multiple profile 200″.
The floating floor can be raised more rapidly owing to this construction in which the multiple cavity profile 200″ has a width greater than that of the profiles described above.
A protective casing realized with a sleeve 310 or a sleeve 320, whose lateral wall is pierced, is mounted on the end piece 250′ closing off the connection end of the profile 200″ to protect it.
In a third embodiment variant represented in
In
Specific end pieces 250a, 25 Gb shown respectively in
In
The same end piece 250a is provided with a wall delimiting one side of the channel 276 and which is prolonged by an edge 278 penetrating the third conduit 240. The water that may be introduced or removed from the third conduit 240 by circulating through the said channel 276 must therefore cross this edge 278. For this purpose see the path of the arrow E′ on the edge 278 in
Hence, when the third conduit 240 of the profile 200″ is being filled, the admitted water enters the profile from the lower section and the expulsed air leaves by the upper section, with the result that it can be almost completely filled with water before another profile connected further along can begin to be filled.
Conversely, when emptying the third conduit 240 of the profile 200″, the water is evacuated through the lower part, with the result that it can be emptied almost completely of its water as soon as the other profile is emptied and that it only lets air into the said profile.

The floating floor incorporating this embodiment variant of the profiles can, by using the covered surface of the swimming pool, capture the solar radiation to heat the water that it contains.
