Description

HYDRAULIC MASSAGE DEVICE FOR DISPENSING
A SUBMERSIBLE SHOWER FOR A PATIENT,
IN A COLLECTIVE OR INDIVIDUAL BASIN
The invention relates to a hydraulic massage device intended to dispense a shower under immersion to a patient, in a collective or individual basin.

 The treatments provided, in collective or individual pools, are so-called mobilization treatments, during which the spa guests carry out selected movements, each holding two support bars sealed in one of the vertical walls of the pool.

 There is, however, another type of treatment, called massage, which is complementary to mobilization, consisting in providing spa guests with a shower under immersion. For this purpose, the basin is provided with submerged nozzles opening at the level of the vertical walls. However, this type of care is rarely provided at present because, unless it considerably increases the number of nozzles, it only allows massage of specific parts of the body.

 The present invention aims to overcome this drawback and has the essential objective of providing a hydraulic massage device allowing massages of any part of the body, from the ankles to the shoulders.

 Another objective is to provide a hydraulic massage device in which the position of the water jet is selected directly by the spa owner himself.

 Another objective is to provide a hydraulic massage device dispensing, as desired, a high pressure shower or a low pressure shower.

 Another objective is to provide a device comprising several individual massage devices whose fully automated cycle is controlled from a central unit making it possible to select the duration of massage, the type of treatment (low or high pressure) ...

 (In order to simplify the description, the hydraulic massage device, in accordance with the invention, is described below in its operating position, that is to say immersed in a basin and placed against a vertical wall of the latter. ).

To this end, the invention relates to a hydraulic massage device intended to dispense a shower under immersion to a patient, in a collective or individual basin, characterized in that it comprises in combination
- a water circulation circuit comprising a hydraulic pump, a pool suction network, and a discharge network,
- at least one submerged nozzle for the outlet of pressurized water, connected to the discharge network, and carried by a mobile support,
- two fixed and submerged holding bars, arranged on either side of the mobile support,
means for moving the mobile support capable of moving it in a substantially vertical direction,
- And control means of the displacement means, comprising actuating members integrated in the holding bars and manually actuable, adapted to generate, on request, either an upward displacement, or a downward displacement, of the mobile support.

 This device therefore comprises at least one nozzle, the vertical position of which is adjusted directly by the user, by action on controls accessible in the massage position, making it possible to precisely direct a jet of water onto the area to be massaged.

 In addition, according to another characteristic of the invention, this device preferably includes two pressurized water outlet nozzles carried by a single movable support, the discharge network comprising two distribution conduits each supplying a nozzle, and adapted to introduce different pressure drops so as to obtain at the outlet of said nozzles two jets of different pressures: a so-called high pressure jet and a so-called low pressure jet.

 The device therefore makes it possible to provide two types of care, selected from a centralized control unit as will be seen below: high pressure care and low pressure care.

Furthermore, and according to a preferred embodiment:
- The means for moving the movable support comprise a hydraulic displacement member, notably a motor or hydraulic cylinder, comprising two supply inlets and adapted to cause a displacement of said support, either upwards or downwards, depending on the inlet powered,

a supply network for each of the supply inputs of the hydraulic displacement member,
the control means comprise a system of distributors arranged on the supply network of the hydraulic displacement member and controlled by the actuating members so as to allow one or the other to be supplied on demand entry of said displacement member.

 The water from the basin sucked in by the pump is therefore used, on the one hand, for hydraulic massage, and, on the other hand, to generate the vertical displacements of the water outlet nozzles. Consequently, the device does not require any auxiliary power to generate the movements of the nozzles.

This hydraulic displacement member can consist of a motor, either centrifugal or vane, actuating a screw / nut carrying the movable support. However, this member preferably consists of a rodless cylinder comprising:
a hermetic body having internally a movable piston delimiting, inside said body, two so-called upper and lower chambers,

the control means comprise a system of solenoid valves arranged on the supply network of the chambers of the jack, and controlled by the actuating members so as to allow, on request, either the filling of a chamber and the emptying of the other chamber, or the reverse process.

 This rodless cylinder has, in particular, the advantage of having a small footprint, and of having no element emerging above the basin. Consequently, it can be installed between two support bars, without reducing the useful volume of this basin.

 Two embodiments of control means can also be advantageously used.

 According to a first embodiment, these control means comprise actuating members consisting of two pears each housed in a holding bar and actuable manually, and two pressure switches each connected to a pear by a capillary, said pressure switches each being mounted in series in an electrical supply circuit of the solenoid valve system.

 According to a second embodiment, the control means comprise actuating members consisting of two light fittings each housed in a holding bar opposite an orifice formed in said bar, and two photoelectric cells each connected to a luminous tip by an optical fiber, and mounted in series in an electrical supply circuit of the solenoid valve system.

These two angles 5 are secured, towards their upper end, to the angle 4 of the box 1, by means of a hinge pin. As shown in Figure 4, this joint, associated with the hinge 2 support of this box 1, allows to reassemble the device on the edge of the pool for maintenance or repair.

 Opposite each of the upper 6a and lower 6b spacers, the frame further comprises two stirrups 7 provided with a front wall 7a parallel to these spacers, and two wings 7b fixed towards their ends on the angles 5. Each of these stirrups 7 also comprises a transverse wall 8 inclined relative to the vertical and extending between the two wings 7b, so as to form with the front wall 7a a housing having a V-shaped section.

 The grab bars 9 of this module consist of two sticks having the shape of a U whose wings are extended by a return 9a at right angles. The brackets 9 are welded, at the end of the angle returns 9a, each on the external face of the wing of an angle 5 of the chassis, orthogonal to the wall of the basin. Thus fixed, these brackets 9 extend orthogonally to the vertical wall of the pelvis.

 The cylinder / water outlet nozzles assembly finally comprises a cable cylinder 10 arranged so as to extend vertically in the basin. The upper and lower ends of this jack are inserted in flanges 11 fixed respectively on and under lower flanges 12 and upper 13. These flanges 12, 13, have the shape of an L with a horizontal wing 12a, 13a support for the flanges 11, and a vertical wing 12b, 13b adapted to be positioned in the V-shaped housing of a stirrup 7.

I1 also comprises an external slide 19 having a rear face provided with a groove of shape adapted to cover the core of the rail guide 15. The maintenance of this slide 19 on this guide rail 15 is moreover ensured by two plates 20 housed in the slides delimited by the web of the rail and fixed to the rear face of the slide on either side of the groove.

 The jack 10 also comprises two connecting cables 21a, 21b between the slide 19 and the piston 16, each of said cables being guided by a return pulley 22 secured respectively to the upper flange 13 or lower 12 by means of two cheeks 23.

 Furthermore, the actuator 10 has two internal upper stops 24 and low 25 intended to obtain a piston stroke 16 equivalent to the length of the guide rail 15. These two stops 24, 25 consist of two tubes arranged inside the body 14 of the jack 10 and fixed respectively on the lower flange 12 and under the upper flange 13.

 The slide 19 of the actuator 10 comprises a front wall pierced with two superposed threaded bores, inside which are screwed two nozzles 26, 27 for water outlet, said bores each communicating with a lateral fluid inlet provided with 'a connecting piece 28, 29.

The cylinder / water outlet nozzles assembly also comprises four connection ends to the hydraulic block, fixed to the upper flange 13
two nozzles 30, 31 for supplying the nozzles 26, 27 connected to the fluid inlets of the slide 19 by means of two flexible pipes 32, 33,
a feed nozzle 34 for the upper chamber 17 of the jack 10, opening directly into this chamber,
- and a feed end piece 35 of the lower chamber 18 of the jack 10, connected to a U-shaped connection end piece 36 fixed under the lower flange 12, by means of a flexible pipe 37.

 Finally, this set of jack / water outlet nozzles is covered with a cover 38 fixed on the angles 5 and provided with a vertical light 39 opposite the nozzles 26, 27 for water outlet.

 The hydraulic circuit for supplying the nozzles 26, 27 and the chambers 17, 18 of the jack 10 is shown in FIG. 5. This hydraulic circuit comprises, first of all, a hydraulic pump 40.

 On the suction side, this circuit includes a water suction pipe 41, immersed in the basin, and comprising a strainer 42, a non-return valve 43, and an isolation valve 44. I1 also comprises a pipe 45 connected to the basin temperature water circuit, or to the filtration circuit of this basin, intended to prime the pump 40 when it is put into service or after draining the basin.

 On the discharge side, the hydraulic circuit comprises two parallel networks supplying respectively, one 46 the nozzles 26, 27 for the water outlet, and the other 47 the chambers 17, 18 of the jack 10.

 The first of these networks 46 comprises a three-way ball valve 48 controlled in rotation in one direction or the other by a motor, and comprising a fluid inlet connected to the discharge pipe, and two fluid outlets each connected to a feed nozzle 30, 31 of a nozzle 26, 27.

 In addition, this three-way valve 48 has offset end-of-travel contacts, so as to introduce different pressure drops in each of the supply conduits 49, 50 of the nozzles 26, 27. This arrangement makes it possible, according to the nozzle supplied, either a high pressure shower or a low pressure shower.

 The second network 47, supplying the chambers 17, 18 of the jack 10, firstly comprises a screen filter 51. Downstream of this filter 51, this network comprises four two-way motorized valves, closed in normal position: a valve supply 52 or 53 and an exhaust valve 54 or 55 for each of the chambers 17 or 18 of the jack 10. These four valves are arranged "crosswise", that is to say distributed in two parallel pipes each comprising series: the supply valve 52 or 53 of a chamber 17 or 18, the connection of the supply line 56 or 57 of this chamber, and the exhaust valve 54 or 55 of the other chamber 18 or 17 .

 The fluid outlet of the two exhaust valves 54, 55 is then connected to a single exhaust line 58 comprising an adjustment valve 59 making it possible to adjust the speed of movement of the jack 10.

 All the hydraulic elements described above, except the non-return valve 43 and the strainer 42, are arranged inside the box 1 arranged on the edge of the swimming pool.

 The supply and management unit for these hydraulic elements comprises an electrical cabinet 60 provided with a programmable automaton, and provided with an electrical supply outlet 61.

The electrical connection and control means comprise, first of all, a connection box 63 placed in the box and comprising four electrical supply outlets:
a direct power output from the pump 40,
- a direct power output from the three-way valve 48,
- two supply outlets each intended to supply the supply valve 52 and 53 and the exhaust valve 54 and 55 to a chamber 17, 18.

 In addition, according to a first embodiment represented in FIG. 6, these electrical connection and control means comprise a box 64 containing two pressure switches 65, 66 double contact and two supply circuits 67, 68 of the supply valves 52 , 53 and exhaust 54, 55 adapted to supply, each simultaneously, the supply and exhaust valves of one of the chambers 17, 18 of the jack 10.

 To this end, one of the contacts of each of the pressure switches 65, 66 is mounted in series on one of the aforementioned supply circuits 67, 68 so as to allow the simultaneous supply, when it is closed, of the supply valves 52 or 53 and exhaust 54 or 55 concerned.

 Furthermore, the two other contacts of the pressure switches 65, 66 are mounted in series in an electrical circuit 69 connected to the connection box 63, and the programmable controller is programmed to deliver a command pulse to start the pump 40. , when these two contacts are closed, generating current continuity in this circuit 69.

 Finally, actuating members integrated in the holding bars 9 are adapted to activate the pressure switches 65, 66. As shown in FIG. 8, these members consist of two pears 70 which can be actuated manually, each housed in a holding bar. 9 and connected to a pressure switch 65, 66 by a capillary 71.

The function of these 70 pears is
- firstly, to generate the starting of the pump 40 by a simultaneous action on the two pears 70 which creates a continuity of current in the circuit 69,
- in a second step, generate either the ascent or the descent of the piston 16 of the jack 10 and therefore of the slide 19, by an action on one or the other pear 70.

Indeed, if the curist presses on a pear 70, one of the pressure switches 65, 66 closes simultaneously causing the opening of the supply valve 52 or 53 of one of the chambers 17 or 18 and of the exhaust valve 54 or 55 from the other room. An action on the other pear 70 likewise causes a reverse movement.

 According to a second embodiment shown in FIG. 7, the electrical connection and control means comprise two photoelectric cells 74, 75, with internal contact 74a, 75a, supplied with 24V. One of these cells 74 is mounted in series in an electrical circuit 76, making it possible to simultaneously supply the supply valve 52 and the exhaust valve 55 of the chamber 17 of the jack. Likewise, the second cell 75 is mounted in an electrical circuit 77 for the simultaneous supply of the supply valve 53 and of the exhaust valve of the second chamber 18 of the jack 10.

 Each of these electrical circuits 76, 77 includes a relay 78 and a contact 79, the closing of which is controlled by the closing of the internal contact of the corresponding photocell 74 or 75.

 In addition, these electrical connection and control means comprise a circuit 82 for controlling the starting of the pump 40, comprising two contacts 80, 81, mounted in series, and each supplied by one of the photoelectric cells 74 or 75 , in order to deliver to the connection box 63 a command signal to start the pump 40, when they are simultaneously closed.

 Finally, the actuating members consist of two light fittings 83, each housed in a holding bar 9, facing an orifice formed in said bar, and connected to a photoelectric cell 74, 75 by an optical fiber 84.

 As before, these control means allow, firstly, to deliver a signal for controlling the start of the pump during the simultaneous closing of the orifice of the two holding bars 9, and secondly, to generate the rise or fall of the slide 19 when closing one or the other orifice.

 The power and management assembly finally includes a remote control keyboard 72 with five keys, connected to the cabinet 60.

 The first key corresponds to a global on / off function of the device.

 The second key selects the position of the three-way valve 48 corresponding to a low pressure shower.

 The third key selects the position of the three-way valve 48 corresponding to a high pressure shower.

 The fourth and fifth keys allow, in the same way, to select the type of care but for a next batch of spa guests.

 In the most common case where several hydraulic massage devices are installed in the same pool, the keyboards of these devices are centralized so as to form a general control console.

 Finally, a common pusher 73 connected to the various cabinets 60 makes it possible, in this case, to lock the operation of the hydraulic massage devices, and offers security preventing the triggering of these devices when, for example, the pool is used for other care such as mobilization.

 The hydraulic device represented in FIG. 9 is strictly identical, in principle, to that described above, and differs only from the latter due to the arrangement of the support frame 5, 6, 7, and of the hydraulic block 1.

 The support frame of this device is, in fact, disposed in a recess 85, formed in a vertical wall of the basin, and closed by means of a closing cover 86 provided with a vertical light opposite the nozzles 26, 27 water outlet.

 The holding bars 9 are, for their part, sealed in the vertical wall on either side of the recess 85, and the hydraulic block 1 disposed in a technical room 87 adjoining the basin.

 This hydraulic massage device designed for specially fitted pools has the advantage of being completely hidden from the walls of the pool. It should also be noted that, given its location, it does not require the presence of a strainer and a non-return valve on the suction network.
