Arrangement of a hydrotherapeutic nozzle head,

The present invention relates to hydrotherapeutic equipment and, more particularly, to the arrangement of a hydrotherapeutic nozzle head for installation in the wall of a container belonging to such equipment.

flush or recessed arrangement of a water-air nozzle head is known. An example of such equipment is described in U.S. Patent No. 3,297,025.

The arrangement of the hydrotherapeutic nozzle head previously used in such systems comprises a recessed housing with a inner end wall that ends in a hemispherical base. A water supply and an air supply both lead to the base. A nozzle assembly with a ball side is installed in the recessed housing, with the ball side being arranged in the base, to allow angle adjustment of the nozzle. The components of such known hydrotherapeutic nozzle head assemblies did not Once they have been installed with all pipe connections, they cannot simply be dismantled and removed.

For functional reasons, it is never necessary to remove a hydrotherapeutic nozzle head arrangement. For the sake of appearance and for good looks, however, the interior surface of the recessed housing is usually chrome-plated and has a luxury finish even gold-plated. Exposing such surfaces to chemicals contained in tap water, or repeated cleaning and polishing Especially subjected to the use of detergents, they will discolor or wear off and a new coating require to restore the original look.

In known arrangements of the type mentioned, this could not be done without removing the pipe connections and the housing itself.

Such a hidden tube at conclusions is very difficult to access.

The object of the present invention is, a novel and to provide improved hydrotherapeutic nozzle head assemblies which are flush or recessed in the wall of a container is built in, while it allows renewal of the polished inner surface of the recessed case without dismantling the To make the entire nozzle head assembly or the pipe connections necessary.

Other objects of the present invention are set out in the following Description of the preferred embodiment thereof expressed in conjunction with the accompanying drawings.

It shows :

Figure 1 is a sectional side view of a hydrotherapeutic Nozzle head assembly according to the present invention

Figure 2 is a plan view of the same.

The water-to-air nozzle head assembly of the present invention is generally designed and constructed to be used for containment to provide an interchangeable lining, which ^ on the one hand represents the inner surface of the nozzle head assembly. Attaching such a chuck enables fundamental changes in construction to be made in the manufacture of the entire nozzle head assembly and the material used.

In a preferred embodiment of the present invention a recessed housing 1 is provided with an inside which ends in a wall 3, which with a hemispherical base 5 is provided. The base 5 has a water passage 7 for a water pipe 8 and an air duct 9 for an air inlet pipe 10 on. At the edge of the open side of the housing 1, an outwardly directed flange 11 is attached, which for purposes of attachment in the Has screw holes arranged at a distance from one another.

In the recessed housing 1, a nozzle arrangement 15 is installed with a ball side 17, which fits into the base 5 and means one removably attached by screws to the rear wall of the housing Retaining ring 19 is held. A seal 21 between the retaining ring 19 and the ball side 17 of the nozzle arrangement 15 is permitted

an angular adjustment of the nozzle assembly 15 while excluding leakage at this point.

The specific details of the construction of the nozzle assembly 15 are not critical to the present invention. The ones in the Nozzle assembly 15 illustrated in the drawings is similar to that shown in U.S. Pat. U.S. Patent No. 3,273,560 describes the nozzle assembly however, could correspond to U.S. Patent No. 3,297,025 mentioned above.

The inner surface of the recessed housing 1 covers a lining 25, the is formed on its inside with an inwardly directed flange 27 which is suitable on the rear end wall of the housing 1 to be applied. On the outside, the chuck 25 is provided with an outwardly directed flange 29 which serves as the mounting flange 11 of the housing 1 is adapted, and encloses the same.

Such a lining 25 is made of metal or as an independent component formed another suitable material, which is a glossy or may have a highly polished surface, and is installed before attaching the retaining ring 19, whereby the chuck 25 with With the help of the retaining ring 19 on the rear end wall of the recessed housing 1 is attached. Thus, by simply removing the retaining ring 19, the chuck 25 itself either for renewal or for

repolishing its surface if that surface has become worn or discolored and requires replacement.

When installing the hydrotherapeutic nozzle head arrangement, the Housing 1 inserted through an opening provided in a wall 30 of the container from the inside and with the help of screws 31 through the k holes provided in the housing flange are held in the wall 30.

Then the water pipe 8 and the air inlet pipe 10 on the back of the housing 1 in the passages 7 and 9 provided for this purpose connected. When inserting the nozzle arrangement 15 into the base 5, the chuck 25 is attached, and by inserting the retaining ring 19 assembly of the nozzle head assembly is complete.

The use of a permanent interchangeable chuck 25 for the stated purpose allows the entire housing 1, including the rear end wall, to be manufactured in one piece and from plastic material, which enables a considerable reduction in material and labor costs. The use of plastic as the material for the housing 1 has the additional advantage of facilitating the use of plastic pipes for the water line 8 and the air inlet pipe 10, both of which can be welded in the passages 7 and 9 provided for this purpose, _{or the like}

From the above description of the present invention in its
