Description

Technical area

The present invention relates to a device that is easily adaptable to a pool, and preferably on the edge of a pool, and which is used to produce fluid jets (including jets of air and / or air). 'water). These jets of fluid (s) can be used for example as massage jets including underwater, and / or for the production of a current under water especially for the practice of stationary swimming against the current. It may also be water jets produced outside the water basin, and forming for example one or more water cascades.

Prior art

In the field of the production of subaquatic massage jets, especially for the hydrotherapy treatment of fatigue or muscular pain, it has been known for many years, for example in the demand for French patent FR 2 137 454 to use a stand-alone device, adaptable to a pool, and having a plurality of hydropneumatic nozzles which have an air inlet and a water inlet. Each nozzle is mounted for its water supply at the end of a tube that is connected to a pump set. The device further comprises an L-shaped housing for housing the nozzles, and water supply pipes of the nozzles. Air intakes connected to the nozzles are further provided in the housing. The device is mounted on the edge of the pool so that the hydropneumatic nozzles are immersed in water and the pump set is placed on the ground at a short distance from the edge of the pool. In operation, the hydropneumatic nozzles are supplied with air and with water drawn from the pool by the pump set, and produce subaqueous massage jets (water and air mixture).

The request for French patent FR 2,221,635 describes a device that is similar to that of the application for French patent FR 2 137 454 , and whose jets are used to create an underwater current that allows the practice of stationary swimming against the current.

The structure of the aforementioned devices of the prior art detrimentally limits the number of nozzles that can be implemented (first disadvantage).

A second disadvantage of the aforementioned devices of the prior art is the lack of modularity, especially because of the integration of the nozzles in an L-shaped housing which serves as a framework for the device and accommodates the fluid supply conduits of the nozzles.

A third disadvantage of the aforementioned devices of the prior art lies in the lack of possibility of adjustment in height of the jet production nozzles. This results in a detrimental way that the depth of exit of the jets is not adjustable, and / or that these devices are not adjustable to better adapt the position of the jets according to the morphology, and in particular the size, the user.

It has already been proposed in the application for French patents FR 2,658,073 devices for producing underwater water jets, allowing a height adjustment of the position of the jets only and not other features.

In this request for French patent FR 2,658,073 , the height adjustment is obtained by mounting the nozzles on a mobile support vertically in translation and operable by a pulley mechanism, the nozzles being connected to the pump unit by flexible connectors.

On the one hand in the device of the application for French patent FR 2,658,073 the use of flexible connectors, which must be long enough to allow the displacement of the nozzles, greatly limits the number of nozzles used, and there is therefore the first disadvantage mentioned above. In the example described, the device comprises only two nozzles.

On the other hand in this device, and similarly to the aforementioned devices publications FR 2 137 454 and FR 2,221,635 , the nozzles are housed in an L-shaped housing used as a frame and housing in particular to the supply ducts of the nozzles, and there is therefore the second disadvantage mentioned above (lack of modularity).

According to a fourth disadvantage, this solution is adapted only for an implementation of vertically aligned nozzles in the direction of movement of the nozzles, but is unsuitable for an implementation of nozzles spaced in a direction transverse to the direction of movement of the nozzles, due in particular to the need in this solution to provide for each nozzle or each vertical alignment of nozzles a vertical window in the housing for the output of the jets.

According to a fifth drawback, the aforementioned devices of the prior art are very impractical to carry, in particular because of their large weight, which makes it very tedious operations of setting up these devices on the edge of the basin or withdrawal of these devices. Thus, even if some devices of the prior art are removable relative to the basin, it is found in practice that their owner is reluctant to remove them in case of non-use, and leaves in practice permanently installed on the basin. Or it is advantageous to be able to easily remove this type of device and store it in the shelter when not in use, to prevent it from being damaged especially during the winter for uncovered basins or to avoid being stolen or degraded by a malicious third party.

Objectives of the invention

A first object of the invention is to propose a device which is easily adaptable to a basin, which makes it possible to produce in the pool jets formed by at least one fluid (in particular water jets, and / or jets air and / or jets of water and air), and which overcomes at least the first, second and fourth aforementioned disadvantages of the devices of the prior art.

A second object of the invention is to propose a device which makes it possible to produce in the water of the pond one or more jets formed of at least one fluid (in particular water jets, and / or air jets). and / or jets of water and air), and which overcomes the third disadvantage mentioned above.

A third object of the invention is to propose a device which makes it possible to produce in the water of the pond one or more jets formed of at least one fluid (in particular water jets, and / or air jets). and / or jets of water and air), and which overcomes the disadvantages of the aforementioned devices in that it is more easily transportable.

Detailed description of the invention

We are represented on figures 1 and 2 , an overview of a preferred embodiment of a device 1 of the invention which is placed in the corner of a pool 2, the pool type, intended to be filled with water. On the figure 2 , the different casings of the device 1 have been removed.

Device (1) / Overview (Figures 1 and 2)

This device 1 comprises two superimposed modules 10 and 11 for the production of subaqueous jets (water + air), a seat 17 and a technical unit 14. The technical unit 14 comprises a casing 140, which is preferably impervious to splashing water. , and inside which are housed means for forced circulation of fluids (turbine for air and pump for water). The invention is not limited to a device comprising two jet production modules, but also extends to devices comprising a single module or to devices comprising more than two modules.

Each module 10 or 11 comprises a plurality of hydropneumatic nozzles (referenced 100 for the module 10, and referenced 110 for the module 11) integrated in the front of a housing referenced 101 for the module 10, and referenced 111 for the module 11) . The nozzles 100 of the upper module 10 are used to produce subaquatic jets (water + air) forming a current that allows the practice of stationary swimming against the current, and / or where appropriate that is used as a massage current, each jet consisting of a water / air mixture. The nozzles 110 of the lower module 11 are used to produce subaquatic massage (water + air) jets.

The two modules 10 and 11 are threaded onto two main tubes 12 and 13 parallel, which pass through the two casings 101 and 111 of the modules from one side. Each main tube 12, 13 has a bent upper portion and is fixed at its upper end to the housing 140 of the technical block 14. The seat 17 is also threaded on the two tubes 12 and 13, and is preferably adjustable in height.

The main tubes 12 and 13 are rigid tubes giving the entire device a certain rigidity facilitating its handling, especially during the implementation operations on the basin or removal of the device. By "rigid" main tube, it is meant that the main tube, under normal mechanical stresses resulting from manipulation of the device under normal conditions, is not deformable, or is elastically deformable (that is to say is not irreversibly deformed and substantially returns to its original shape in the absence of mechanical stress), in contrast in particular with a flexible or flexible tube that can take any form. For example, the main tubes 12 and 13 are metal tubes, in particular stainless steel or aluminum, or plastic tubes including PVC or tubes of composite material.

In the lower part, each tube 12, 13 is preferably equipped with a foot 12a, 13a with adjustable height, which is for example screwed through a wall closing the lower end of the tube 12, 13.

As illustrated on the figure 1 , the device 1 is set up on the edge of the pool 2, and the height of the legs 12a, 13a is adjusted to such so on the one hand that the technical block 14 is placed outside the water on the ground S near the edge of the pool 2, and secondly that the two tubes 12 and 13 are supported on the bottom 20 of the pool via the feet 12a and 13a, the nozzles of the two modules 10 and 11 being positioned below the level of the upper edge ( figure 1 21) of the pool.

Preferably, the device 1 is simply placed and is not fixed, which facilitates its introduction and removal. However, in another variant (not shown), the device could be fixed, preferably removably, to the floor and / or the wall of the pool, by any suitable fastening means. Also, in another alternative embodiment (not shown), the device may comprise, at the housing 101 and / or 111, lateral support means, which are designed so that, once the device mounted on the edge of the pool, the module 10 and / or the module 11 bear against the vertical side wall 22 of the pool.

In the particular variant embodiment illustrated, the two rigid tubes 12, 13 serve mainly two functions. They serve as frame to the device rigidly connecting the modules 10 and 11 of jetting equipment compartment 14, and so allow easy handling of the device 1 during its installation or removal (1 ^st function); they serve as transport conduits for the fluids (water and air) supplying the nozzles 100 and 110, as will become more clearly apparent hereinafter. In addition, the bent shape of the two tubes 12, 13 at the top gives the unit an aesthetic appearance reminiscent of the traditional form of a pool ladder.

In the context of the invention, the main tubes 12 and 13 may have any cross section (circular, square, ...), the circular section being however preferred. Each main tube 12 or 13 may consist of a single piece, or preferably be constituted by the assembly of several tubular elements end to end.

Technical Block 14 / Figures 12 and 15

• une pompe 141 (pour l'alimentation en eau des buses), dont l'admission (aspiration) est raccordée au tube 12 au moyen d'un raccord de pompe coudé 142, et dont la sortie (refoulement) est raccordée au tube 13 au moyen d'un raccord de pompe coudé 143,
• une turbine 144 (pour l'alimentation en air des buses), dont l'admission d'air communique à l'air libre, et dont la sortie (refoulement d'air) est raccordée à un conduit souple 15 de refoulement d'air.

The technical block 14 comprises a casing 140 in which are housed:

• a pump 141 (for the supply of water to the nozzles), the intake (suction) of which is connected to the tube 12 by means of an elbow pump connection 142, and whose outlet (delivery) is connected to the tube 13 at the means of an elbow pump connection 143,
• a turbine 144 (for the air supply of the nozzles), the air intake of which communicates with the open air, and whose outlet (air discharge) is connected to a flexible duct 15 of air discharge .

The pump connector 142 further includes a T portion 142a. The flexible conduit 15 is partially inserted within the pump connector 142 and the tube 12 via the T-portion 142a of the pump connector 142. .

With reference to the figure 15 , the casing 140 is further equipped with two wheels R, which facilitate its movement on the ground during transport.

Pivoting tubes 12 and 13

According to an additional and optional feature of the invention, the two tubes 12 and 13 are pivotally mounted with respect to the casing 140 of the technical block so that the tube assembly 12, 13 / modules 10, 11 / seat 17 can pivot between two positions: the operating position illustrated on the figure 1 , and an illustrated transport position on the figure 3 . In this variant embodiment, the pivot angle between the two operating and transport positions is slightly greater than 180 °. On the figure 3 the arrows F and T symbolize the directions of rotation to bring the tube assembly 12, 13 / modules 10, 11 / seat 17 respectively into the operating position and into the transport position

With reference to the figure 3 , the two side walls 140a of the housing 140 comprise two recesses 140b in which are housed respectively the two upper bent portions of the tubes 12 and 13, when the tubes are in the transport position. More particularly, the two recesses 140b of the housing 140 are designed so that the two tubes 12 and 13 abut in the two recesses 140b when the tubes are in the transport position, and are locked in rotation in the direction T by the two recesses 140b of the casing 140. Preferably, in the transport position of the device, the weight of the two modules 10 and 11 exerts, with respect to the axis of rotation of the tubes 12 and 13, a pair which rotates the two tubes 12 and 13 in the direction T, which allows a stable support of the two tubes resting in the two recesses 140b of the housing 140.

We have shown on Figures 4 and 5 , the detail of the connection between the tube 12 or 13 and the pump connection 142 or 143. This connection is made by means of a rotating connection 16, which allows a sealing connection between the tube 12 (13 respectively) and the connection pump 142 (respectively 143) through the side wall 140a of the housing 140, while allowing pivoting, in both directions and along its central axis A, the tube 12 (respectively 13) relative to the side wall 140a of the housing 140.

More particularly, this rotating connector 16 comprises an insert 160 having a through central passage 160a, an external shoulder 160b, and an internal shoulder 160c. This insert is mounted through the wall 140a of the housing 140 of the technical block, so that the outer shoulder 160b of the insert 160 bears on the outer face of the wall 140a of the housing 140. The insert 160 is in further attached to the side wall 140a by gluing, welding, or screwing.

A low-cut ring 161, on which is fixed an outer annular shoulder 161a, is threaded and fixed on the end of the tube 12 (respectively 13) for example by being welded to the tube 12 (respectively 13). Two Belleville washers 163a, 163b are further threaded onto the ring 161 on either side of the annular shoulder 161a. An outer cowling 162 having a central recess 162a and a central through passage is also threaded on the ring 161.

The end of the tube 12 (respectively 13) carrying the ring 161 is inserted in the through passage 160a of the insert 160, so that the shoulder 161a of the ring 161 abuts against the outer shoulder 160b of the insert via the Belleville washer 163a. The cowling 162 is fixed against the outer shoulder 160b of the insert 160 so that the central recess 162a of the cowling 162 comes into contact with the other Belleville washer 163b. The end of the tube 12 (respectively 13) bearing the ring 161 is thus locked in translation relative to the insert 160, but can pivot about the central axis A of the tube 12 (respectively 13).

Opposite the end of the tube 12 (respectively 13), the end of the pump connector 142 (resp 143) is inserted into the insert 160 until it abuts against the internal shoulder 160c of the insert 160, and is further attached to the insert 160, for example by gluing. The tube 12 (or 13) thus communicates with the pump connection 142 (or 143) through the side wall 140a of the housing 140 of the technical block 14. As illustrated on the figure 5 in order to ensure a tight connection between the tube 12 (or 13) and the pump connector 142 (respectively 143), the rotary coupling 16 comprises two seal 164 interposed between the ring 161 and the insert respectively. 160 and the cowling 162.

Handling the device for transport / Figures 1 and 3

To remove and store the device 1, when installed on the edge of the basin ( figure 1 ), the user rotates upwardly the two rigid tubes 12, 13 carriers, so as to tilt the assembly tubes 12, 13 / modules 10 and 11 / seat 17 out of the water, and up to that the device is configured in transport position, the tubes 12 and 13 being abutted against the housing 140 (position of the figure 3 ). In another alternative embodiment (not shown), the device may be equipped with a jacking assistance system (s) or motorized type, to assist in the pivoting of the main tubes 12 and 13 into their transport position, especially when the jet production modules and the seat are out of water.

If the device 1 is fixed to the ground, the user removes said fasteners in sort of disengage the device from the ground. Then, the user slightly tilts the technical block 14 so as to position it on the ground on these rollers A. The transport of the device, for example to its place of storage, is carried out simply and with little effort in pulling the device to the ground through the rigid tubes 12, 13, without lifting it completely off the ground (the technical block 14 being kept in contact with the ground). The rollers R of the technical block 14 make it easier to move the technical block 14 in contact with the ground. Transport and installation of the device 1 on the basin 2 are performed by carrying out the above operations in the reverse order.

Module 10 swimming against the current / height adjustment (Figures 10)

With reference to the figure 10 , the counter-current swimming module 10 comprises three nozzles 100 (a central nozzle and two lateral nozzles) which are integral with the casing 101 (not shown in FIG. figure 10 ), which casing 101 is secured to two rigid tubes 102a and 102b. The two tubes 102a and 102b are threaded respectively on the two tubes 12 and 13, and have an internal diameter greater than the outer diameter of the tubes 12, 13. The module 10 against the current (nozzles 100 / housing 101 / tubes 102a , 102b) can thus slide relative to the two tubes 12 and 13 At the top, each tube 102a, 102b is further equipped with a gland system 103c. When the two gland systems 103c are loosened, the module 10 can slide along the two tubes 12 and 13 and be adjusted in height. Once the height position of the module 10 has been correctly adjusted, it is sufficient to manually tighten the two gland systems 103c, to lock the module 10 in position relative to the tubes 12 and 13. The gland systems 103c will be able to be replaced by any equivalent means allowing blocking / unlocking of the module 10 with respect to the tubes 12 and 13, in order to adjust the position of the module 10.

Massage Module 11 and Seat 17 / Seat Height Adjustment (Figures 1, 6, 7 and 8)

In the particular example illustrated, the nozzles 110 of the massage block 11 are arranged in the form of four columns of nozzles (two outer columns 110a for a lateral massage, and two central columns 110b for a back or ventral massage). The assembly formed by these nozzles 110 is integral with the housing 111. In a manner identical to that previously described for the module 10, this housing 111 is secured to two rigid tubes threaded onto the main tubes 12 and 13, and adapted to slide relative to these tubes 12 and 13, so that the module 11 is adjustable in height. The locking in translation of the module 11 relative to the main tubes 12 and 13 is made for example in the same way as for the module 10, that is to say by means of gland systems.

The seat 17 is integral with the module 11 and is preferably adjustable in height relative to this module 11.

More particularly, in the embodiment shown, the seat 17 is integral, preferably foldably, a support 18. This support 18 comprises two short tubes 181a and 181b which are rigidly interconnected by a spacer 182, by example welded to the tubes 181a and 181b. The two tubes 181a and 181b are respectively threaded onto the two tubes 12 and 13 and are able to slide relative to the two tubes 12 and 13, in order to allow height adjustment of the seat 17.

The seat 17 and secured to the spacer 182 of the support 18, and is preferably foldable. On the spacer 182 is further fixed a vertical square tube 183 equipped with a vertical rack 184.

For its adjustment in height, the support of the 18 is further equipped with manual adjustment means 19 comprising a pinion 191 rotatably actuable by an adjusting handle 192. This handle 192 is connected to the pinion 191 by a shaft 193 which has passed to through a cut 112a of a connecting plate 112 fixed to the casing 111 of the module 11. At its end opposite the handle 192, this shaft 193 is rotatably supported and guided in translation by a U-shaped part 112b which is fixed on the connection plate 112. On this end of the shaft 193, is mounted a spring 194 which bears on the U-shaped part 112b. On the shaft 193 is further mounted a locking piece 195 (in this case a locking nut), intended to cooperate with the cut 112a to ensure a rotational locking of the shaft 193.

• une première position (dite de réglage) dans laquelle le pignon 191 engrène avec la crémaillère 184, le ressort 194 étant comprimé, et l'écrou de blocage 195 étant dégagé de la découpe en U 112a (position de la figure 7), et
• une seconde position (dite de blocage) dans laquelle l'écrou de blocage 195 est positionné dans la découpe en U 112a et permet un blocage en rotation de l'arbre 193.

The shaft 193 is movable in translation along its longitudinal axis between two positions:

• a first position (called adjustment) in which the pinion 191 meshes with the rack 184, the spring 194 being compressed, and the locking nut 195 being disengaged from the U-shaped cutout 112a (position of the figure 7 ), and
• a second position (called locking) in which the locking nut 195 is positioned in the U-shaped cutout 112a and allows rotational locking of the shaft 193.

The height adjustment of the seat 17 is independent of the height adjustment of the module 10 and operates in the following manner.

Initially, the shaft 193 is pushed back and held in the aforementioned second locking position by the spring 194. The user exerts a push on the handle 192, so as to compress the spring 194 and to bring and maintain the shaft 193 in the first setting position. While maintaining the shaft 193 in this adjustment position, the user rotates the handle in one direction or the other so that the pinion 191 is rotated, and the seat 17 is lowered or raised. seat 17 is adjusted, the user releases the handle 192. The spring 194 pushes the shaft 193 in its second locking position. The seat 17 is then locked in translation relative to the two tubes 12 and 13 by means of the locking nut 195 which cooperates with the U-shaped cutout 112a.

The invention is not limited to the particular system for adjusting the height of the seat relative to the two tubes 12 and 13, which has just been described, but this height adjustment system may be replaced by any equivalent adjustment means fulfilling the same function, and manual or motorized operation.

Elements of the air circuit of the modules 10 and 11 (FIGS. 11 and 9)

With reference to the figure 11 , an annular chamber C is formed between the inner wall of the tube 102a and the outer wall of the tube 12. This annular chamber C is closed, in the lower part by a sealing ring 103a, and in the upper part by the seal 103b of the press -Toupe 103c.

The aforementioned flexible air discharge duct 15 which is connected to the outlet of the turbine 144 and which is partly housed inside the tube 12, has at its free end a tubular sleeve 150 fixed, for example by gluing. This sleeve 150 is sealingly closed by a plug 151. The sleeve 150 is clamped to the inner wall of the tube 12 by means of a threaded hull 152 (shown in FIG. figure 14 ). This hull 152 also makes it possible to communicate the interior of the flexible conduit 15 with the annular chamber C. In its median part, the tube 102a comprises a T-connector 102c, which forms a main air intake A1 for the module 10. This main air intake A1 is connected to a flexible tube 107, and makes it possible to communicate the annular chamber C of air discharge with the tube 107.

Opposite the air discharge chamber C, the end of the tube 107 is connected to the inlet of a three-way valve 108. At the outlet the valve 108 is connected by flexible pipes 108a to each nozzle 100 of the module 10 against the current and the massage module 11 by a flexible tubular 108b ( figure 9 ). This valve 108 is used to adjustably distribute the incoming air supply through the flexible conduit 107 to the nozzles 100 of the block 10 swimming against the current and / or to the nozzles 110 of the massage module 11. The nozzles 110 of the module 11de massage are thus supplied with air, from the module 10 swimming against the current, via the valve 108.

More specifically, with reference to the figure 9 , the massage module 11 comprises a T-connector 113, forming the main air intake A'1 of the massage module 11. This T-connection 113 (main air intake A'1 of the module 11) is connected input for its air supply to the aforementioned flexible tubing 108b. At the outlet, the T-piece 113 is connected on the one hand, by means of a pipe 114, to the network formed by the two columns 110b of dorsal nozzles, and on the other hand, by means of pipes 115, to the formed network. by the two columns 110a of lateral nozzles.

Elements of the water circuit of the modules 10 and 11 (FIGS. 10 and 8)

With reference to the figure 10 , an annular chamber C 'is formed between the inner wall of the tube 102b and the outer wall of the tube 13. This annular chamber C' is closed, in the lower part by a sealing ring 103a, and in the upper part by a seal 103b .

The wall of the tube 13, in its portion constantly covered by the tube 102b, is pierced with one or more through holes, preferably of oblong shape, which make it possible to communicate the inside of the tube 13 with the annular chamber C ', and supplying water to the chamber C 'from the tube 13.

In its middle part, the tube 102b has a T-fitting 102c, which forms a main inlet of water A2 ( figure 10 ) for the module 10. This main water intake A2 is connected to one end of a duct 102d, and makes it possible to put in communication the annular chamber C 'of water discharge with the duct 102d, for the supply of water. water from this conduit. The other end of the conduit 102d is connected at the input to a three-way valve 109a. This valve 109a is connected at the outlet to the nozzles 100 of the block 10 swimming against the current by means of flexible tubes and a four-way valve 109b. This four-way valve 109b is connected at the output to the nozzles 110 of the massage module 11. The nozzles 110 of the massage module 11 are thus supplied with water from the module 10 swimming against the current.

More specifically, the massage module 11 comprises two main flexible pipes 116 and 117 respectively forming two main water admissions A'2 ( figure 8 ). The main pipe 116 is connected at one end to an outlet of the valve 109b, and at its other end to the network of lateral nozzles 110 (columns 110a) via successively a T-fitting (masked on the figure 8 ) and secondary conduits 116a. The main tubing 117 is connected at one end to an outlet of the valve 109b, and at its other end to the network of backbone nozzles 110 (columns 110b) via a T-fitting 117a.

Complete water supply circuit

The operation of the complete water supply circuit of the device will now be detailed with reference to figures 8 , 10 and 12 . In these figures, the course of the water is symbolized by arrows.

The tube 12 of the device comprises at least one water suction opening (not visible in the drawings) which is formed in the lower part of the tube 12 (for example below the level of the massage module 11), and which is preferably oriented towards the side wall of the basin. This water intake opening may further be equipped with a grid or a filter or equivalent, to prevent the penetration of any foreign body in the water circuit.

With reference to figures 10 and 12 when the pump 141 is turned on, water from the tank 2 is sucked into the tube 12 through this water inlet opening of the tube 12, and goes up inside the tube 12 to the inlet opening of the pump 141. This water is discharged by the pump 141 ( figure 12 ) inside the tube 13, and down again in this tube 13 into the water discharge chamber C '( figure 10 ), then is discharged towards the distribution valve 109a via the main water inlet A2 of the module 10 and via the conduit 102d. From this valve 109a, the nozzles 100 of the module 10 are supplied with water, as well as the nozzles 110 of the module 11 (via the valve 109b and the two main water admissions A'2 of the module 11). The annular chamber C 'advantageously allows a water supply of the nozzles of the modules for different height positions of the module 10 with respect to the tube 13.

Complete air supply circuit (Figures 9, 11 and 13)

The operation of the complete air supply circuit of the device will now be detailed with reference to figures 9 , 11 and 13 . In these figures, the air is symbolized by arrows.

When the turbine 144 is turned on ( figure 13 ), air is injected into the duct 15, and is forced into the annular chamber C ( figure 11 ). This air in the chamber C passes, via the main air intake A1 of the module 10, into the conduit 107 supplying the valve 108, and is redistributed by this valve 108 to the nozzles 100 of the counter-current swimming module 10 ( via the distribution manifolds 108a) and / or to the nozzles 110 of the massage module 11, in particular via the tubing 108b, the main air intake A'1 (connection 113) of the module 11, and the tubings 114 and 115 The annular chamber C advantageously allows an air supply of the nozzles of the modules for different height positions of the module 10 with respect to the tube 12.

The invention is not limited to the preferred embodiment which has just been described in detail with reference to the appended figures. In particular, and non-exhaustively, the main tubes are not necessarily rigid tubes. Instead of the two separate tubes 12, 13, the device could, in a so-called monotube version, comprise a tube partitioned by at least one internal longitudinal wall into at least two compartments, or a single main tube, preferably rigid, at the inside which have passed one or more conduits for the supply of fluid (s) of the jet production modules.

The massage module 11 is not necessarily supplied with water and air from the counter-current swimming module 10, but can be connected directly to the main tubes 12 and 13, without passing through the module 10. More particularly, and in a manner comparable to that previously described for the module 10, the module 11 may comprise fluid discharge chambers (C or C ') for a feed of nozzles of the module at different positions of the module 11 with respect to the main rigid tubes 12, 13

The main tube or tubes 12, 13 which connect the jet production modules to the technical unit are not necessarily mobile with respect to the technical block, but may, in a less advanced embodiment, be fixed with respect to the technical block.

In addition, when the main tube or tubes 12, 13 are movable relative to the technical block 14, they are not necessarily articulated in rotation with respect to the technical block, the essential in this case being that these tubes are movable relative to the technical block 14 between an operating position and a transport position in which the device can preferably be manipulated and moved while maintaining the technical unit in contact with the ground. In another variant embodiment, each main tube 12, 13 could be movable in translation relative to the technical block for example by sliding relative to the housing of the technical block. This mobility with respect to the technical block can also combine a rotation and a translation.

The support (tubes 12, 13) supporting the jet production modules 10, 11 and the seat 17 is not necessarily of the tubular type, but may more generally be constituted by any structure mechanically connecting the nozzles to the technical unit. The support (tubes 12, 13) is not necessarily rigid.

The support, whatever its structure, is not necessarily articulated in rotation with respect to the technical block, but is more generally mobile with respect to this technical block, the essential thing being that this support is mobile with respect to in the technical block 14 between an operating position and a transport position in which the device can preferably be manipulated and moved maintaining the technical block in contact with the ground. In another variant embodiment, the support could be movable in translation with respect to the technical block, for example by sliding relative to the housing of the technical block. The mobility of the support compared to the technical block can also combine a rotation and a translation.

When the support is of the tubular type, replacing the two separate tubes 12, 13, the device can, in a so-called monotube version, comprise a tube partitioned by at least one internal longitudinal wall into at least two compartments, or a single main tube , preferably rigid, inside which are passed one or more conduits for the supply of fluid (s) of the jet production modules.

In the preferred variant which has been described, the technical block comprises a turbine 144 which makes it possible to discharge air towards the nozzles of the modules 10 and 11. In another variant embodiment, all or part of the nozzles of a module could only work by venturi effect; in this case, it is sufficient to provide for the module nozzles an air intake outside the pond water. This air intake can be achieved by means for example of an air duct such as the duct 15 previously described, said duct not being in this case connected to a turbine or the like, but opening to the open air to ensure the required air intake.

In the preferred embodiment illustrated in the drawings, the main tubes 12, 13 bear on the bottom of the basin. This characteristic, although preferential, is not essential. In another variant, the device can be designed so that when fitted to a pool, it does not rest on the bottom of the pool, but is supported on the vertical wall or walls of the pool. Also, a device of the invention may combine a support on the bottom of the basin and a lateral support on the vertical wall or walls of the basin.

Preferably, as has been described, the technical block 14 is positioned outside the pond water. Nevertheless, in the context of the invention, it is also conceivable to produce a device whose technical block 14 is completely or partially immersed, once the device adapted to a basin.

In the context of the invention, all jet production modules are not necessarily immersed in the pond water. In another variant of the invention, the device may comprise a jet production module, whose nozzles are out of the water when the device is adapted to a basin, and which makes it possible to produce, outside the water basin, jets directed towards the basin such as for example jets that form one or more cascades of water falling into the basin.
