Shower head for a hand shower

The innovation concerns a shower head for a hand shower whose V / ater outlet side an aerator and sieve rings concentrically surrounding the aerator are provided, the optional can be acted upon with water.

The same shower head should, depending on its intended use emit a relatively hard or a relatively soft water jet mixed with air: Z.I · :. is when using the Shower head when showering the former, when washing hair the latter is desirable. Intermediate positions should be possible, even during operation of the shower head.

The function of the fire is to build a shower head create that meets the above-mentioned requirements, (is easy to set up and handle and elegant. According to the innovation, this object is achieved by a V / ater inflow line attachable screw-in piece and a after Kind of a motion screw head piece connected to the screw-in piece, which is provided with a shoulder and at a distance from the Paragraph is equipped with a retaining ring, both of which are provided as sealing surfaces for sealing rings, which are parallel at a distance from each other on a distributor attached to the screw-in piece are provided dos with an axial water inlet hole and provided with radial bores opening out between the sealing rings and starting from the water inlet bore

Π Γ- / I

is. In the case of the innovation, the head piece only needs to be rotated between two end positions in order to achieve the desired water jet to obtain. When the head piece is rotated, its axial position relative to the fixed screw-in piece is changed becomes the position of the sealing surfaces on the shoulder and on the retaining ring that are present or attached to the head piece and moved with the head piece adjusted based on the sealing rings connected to the screw-in piece and fixed with it on the distributor piece. In the upper end position of the shower head, the water inlet channel for the aerator is closed; in the lower end position the one for the Siebring. The other water inflow Lranal is respectively fully open. Intermediate positions are adjustable. The shower head does not require any additional levers or adjusting screws or the like for ssLne adjustment.

Advantageous refinements of the innovation are set out in the subclaims specified. An embodiment of the innovation is shown in the drawing and is described in more detail below. Show it:

Pig. 1 partly in longitudinal section, partly in side view, for the sake of clarity exploded view of a shower head;

Pig. 2 the side view of the head piece of the in Pig. 1 shower head shown;

Pig. 3 the front view of the in Pig. 2 head piece shown from the water inlet side;

Pig. 4 shows a longitudinal section through the in Pig. 1 shown Distributor on an enlarged scale.

The shower head chosen as an exemplary embodiment has a head piece 1 or housing. On the side connecting to a water inflow line, the head piece 1 is screwed to a screw-in piece 2 into which a distributor piece 3 is screwed in the center. The distributor piece 3 passes through a retaining ring 4, which is screwed to the head piece 1. On its water outlet

On the left side, the head piece 1 is stranded with an aerator insert 6 which accommodates a commercially available aerator. Between the aerator insert 6 and aem head part 1 are interlocking sieve rings 5 are provided.

The inside of the head piece 1 has a perforated partition, the remaining part of which is an annular shoulder forms. The annular shoulder 11 serves on the one hand as a stop for the distributor piece 3 in its thin end position and on the other hand for the aerator insert 6. A ring-shaped one close to the shoulder 11 on the water inlet end

the shoulder 12 and a thread 13 into which / retaining ring 4 is screwed. The thread 13 is followed by another annular paragraph 14-. The Rirg-shaped shoulder 14 is penetrated by evenly distributed on a circle, essentially axially extending passage openings 15 which connect the space on the water inlet side of the shoulder 11 with that on the water outlet side. The water runs through these passage openings 15 when the shower head is set to "shower jet ¹¹ ". Following the annular shoulder 14, a cylindrical guide surface 16 and a thread 17 for the screw-in piece 2 are provided on the water inlet side. On the water outlet side a neck 19 provided with an internal thread 18 is connected to the shoulder 11, with which the aerator insert 6 is screwed The passage openings 15 open onto the outer wall of the neck 19 and the inner wall of the head piece 1.

The wall 7 of the head piece 1 points on the water outlet side inside a shoulder 71 on which the outer one of the sieve rings 5 is applied. On the outside, the wall 7 is provided with longitudinal grooves 72 which facilitate the rotation of the head piece 1. On the water outlet side the wall 7 has a smooth, inwardly angled Edge 73 on. The iand 73 wears several on its circumference Markings 74. The markings 74 give the direction

the
on, in / the head piece 1 must be rotated in order to adjust the shower head in the direction of "shower jet" or "air flow". The surface of the head piece 1 exposed by the longitudinal grooves 72 can be provided with a layer 75 - as shown in ^{dash-dotted lines in Jo 1} Ig. 1 - to give the shower head a special look, for example with a layer of leather grain.

The screw-in piece 2 has a bore 21 with an internal thread 22 on the side facing away from the shoulder ti. With this internal thread 22, the screw-in piece 2 and thus the entire shower head is connected to a water inflow (not shown). The bore 21 accommodates a seal and sieve (also not shown) for collecting dirt particles. On the outside, the egg screw piece 2 is widened on the end face in the manner of a flange 25 and provided with an external thread 26. The thread 17 of the head piece 1 is screwed onto this external thread 26. By turning the head stack I, it is further attached to or removed from the screw piece 2 A .dals 2b is formed coaxially on the bottom of the .bore 21. The rials 2'y is provided with an internal thread 24 into which the distributor piece 3 is screwed and the retaining ring ^z! · in still su descriptive V / else related to dos Veatoilerstück> adjusted so that the diversion of the V / ater inside the shower head, it takes place. in the adjoining the flange 25 Z ylinderfluche 27 a groove is embedded with the ,, ^e: NEM Dichtri.ag is filled 23rd The sealing ring 28 seals the shower head to the outside.

two axially spaced apart and each with a sealing ring 35, 36 filled annular grooves. Radial bores 37, which are in communication with the water inlet bore 38, are provided between the sealing rings 35 »- o.

When the one end position is reached in which the thread 17 of the head piece 1 is predominantly screwed onto the external thread 26 of the screw-in piece 2, the sealing ring 35 rests on the shoulder 11. In this position, the water does not flow through the aerator insert 6, but through the passage openings 15 and thus through the sieve rings 5. When the other end position is reached, the other sealing ring 36 rests on the retaining ring 4, which prevents the screwing-out movement of the head piece 1 be ₇ borders. In this position the water does not flow through the passage openings 15 and the sieve rings 5 »but through the aerator insert 6. Intermediate positions between the end positions are possible.

The retaining ring 4 is designed as a crown nut 41 on its one end face. In the area of the crown nut 41, the retaining ring 4 has an inner flange 42. With its external thread 43, the retaining ring 4 is screwed into the thread 13 of the egg-head piece 1. A part of the distributor piece 3 passes through it. The retaining ring 4 is rotated with the head piece 1, whereas the distributor piece 3 with the screw-in piece ¹ : 2 retains its position unchanged. The inner flange 42 forms a seal with the sealing ring 36. This seal is closed when the head piece 1 is turned to the "aerator jet" position.

On the water outlet side are in the head piece _x 1-in on itself

The aerator insert 6 is against the shoulder 11 depressed; the sieve bars 5 resting against one another with their inner and outer conical surfaces 51 »52 the wall 7 of the head piece 1. The sieve rings 5 have their outer lateral surfaces 52 in the direction of the surface lines

fine grooves 53 through which dos water in the position of the "Shower jet" flows through the shower head. To support the sieve ring with the largest diameter on its outer surface and of the sieve ring with the smallest diameter on its inner surface, the aerator insert is on the outside an annular projection 61 and the wall 7 the abmbz 71 on.
