  • Firm tightening is indeed essential here to ensure sealing by sufficient crushing of the two annular seals on either side of the wall of the bathtub.
  • the stopper of the nozzle thus formed comprises one or more through channels constituted by axial cylindrical holes opening into an internal recess communicating with the outlet orifice of the hollow body, the number, the distribution and the diameter of these holes being established as a function of the various therapeutic effects sought.
  • This known nozzle is suitable for a bathtub intended for a well-defined therapeutic effect which does not require frequent dismantling, which is the case for installations of balneotherapy institutes comprising several baths each adapted to a particular therapeutic effect different from the others.
  • the body of the nozzle is no longer retained against the wall of the bathtub after unscrewing the plug and falling, and this risks causing the need for concomitant disassembly of the main installation of the bathtub, which is the case in particular during the disassembly of the nozzles from the bottom thereof.
  • the hollow body containing an admission valve with elastic retaining, is constituted by a screw with a head. support whose rod is intended to pass through a hole in the wall of the bathtub and whose head is intended to be pressed against this wall, inside the bathtub, the threaded hole of its orifice outlet leading to the external face of this head.
  • the valve After threading the threaded rod of the hollow body into the hole in the wall of the bathtub, from inside the bathtub, the valve is fixed by means of a nut screwed onto said rod under this wall, and the sealing of this fixing is ensured by means of an annular seal disposed between the nut and the wall in question.
  • a threaded plug pierced with a cylindrical through channel and comprising a convex support head, is screwed into the hollow body from inside the bathtub, its support head abutting against the support head of the hollow body at the end of screwing.
  • the threaded plug is screwed onto a threaded part of the hollow body of the hydromassage nozzle and comprises a head. convex support coming to bear, by means of an annular seal, against the interior wall of a bathtub. This results in the disadvantage of having to separate the body of the massage nozzle from the wall of the bathtub each time the injection channel is cleaned.
  • the invention aims to further increase the simplicity of structure and maintenance of the nozzles to which it relates to better respond to private installations with a single bathtub.
  • the nozzle according to the invention conforms to that defined in claim 1.
  • the nozzle according to the invention combines the advantages already stated with greater simplicity of the structure of its threaded plug, and increased ease of maintenance.
  • the shaped channels of grooves in the thread of the plug in addition to their simplicity of execution, have the advantage of increasing the ease of their cleaning, once the plug is removed.
  • FIG. 1 clearly shows the hollow body 1 in the form of a nut of the known nozzle already mentioned with its inlet orifice 2 intended to be connected in the usual way to a water and / or air supply pipe under pressure, not shown, and its threaded outlet orifice 3 opening onto a face 4 intended to be supported on the external face of a wall 5 of a bathtub, opposite a hole 6 thereof.
  • the threaded plug 7 of this known nozzle constitutes a support head screw 8, the threaded rod 9 of which is intended to be threaded into the hole 6 of the wall 5, from inside the bath, and screwed into the threaded hole 3 of the hollow body 1, while the head 8 is intended to bear against this wall 5 when the plug 7 is screwed into the hollow body 1.
  • the tightness of the fixing obtained by tightening the wall 5 between the head 8 of the plug 7 and the face 4 of the hollow body 1 is ensured by two annular seals 10 and 11.
  • the first annular seal 10, of large rectangular section, is disposed between the hollow body 1 and the wall 5 to avoid any risk of leakage of water and / or pressurized air between these two elements.
  • the second annular seal 11, of the "o-ring" type, is disposed between the head 8 of the plug 7 and the inner face of the wall 5 of the bathtub.
  • Figure 2 highlights the hexagonal hole 12 of the outer face of the plug 7 intended to allow firm tightening using a hexagonal wrench, however that the hollow body 1 visible in FIG. 1 has on its periphery a cylindrical hole 13 intended to allow its retention by a claw wrench.
  • the water and / or pressurized air injection channels of the plug 1 are here constituted by cylindrical holes 14 opening into a recess 15, the number and the diameter of these holes obviously being able to vary according to the desired therapeutic effect. .
  • FIG. 1 shows that after unscrewing this plug 7, nothing can prevent the hollow body 1 from falling.
  • the embodiment of the nozzle according to the invention shown in FIG. 3 overcomes this drawback in a simple manner and in itself brings still other advantages.
  • the hollow body 16 of this nozzle constitutes a support head screw 17 whose rod 20, 21 is intended to be passed through a hole 18 of a wall 19 of a bathtub and whose head 17 is intended to be pressed against this wall 19 inside the bathtub.
  • the rod 20, 21 of the hollow body 16 is composed of a threaded upper part 20 located under its head 17 and of an end part 21 having on its side wall an inlet orifice 22 intended to be connected in the usual way to a pipe, not shown, for supplying water and / or air under pressure.
  • the hollow body 16 comprises an outlet orifice constituted by a threaded axial hole 23 opening onto the outer face 24 of its head 17 and communicating with the inlet orifice 22 by means of a recess 25 and a conduit 26.
  • the hollow body 16 thus formed is intended to be fixed to the wall 19 of the bathtub, after threading its rod 20, 21 into the hole 18 of this wall, by means of a nut 27 screwed onto the threaded part 20 of this rod.
  • the threaded plug 29 of the nozzle according to the invention which is intended to be screwed into the threaded outlet orifice 23 of the hollow body, consists of a threaded portion proper 30 extended on its underside by a coaxial cylindrical boss 31, of smaller diameter.
  • This boss 31 is intended, at the end of the threading plug screwing stroke 29 in the orifice 23 of the hollow body 16, to bear against the bottom 32 of the recess 25 of the latter, while the upper face 33 of this plug comes level off the upper face 24 of said hollow body.
