Description

The invention relates to a sanitary outlet fitting according to the preamble of claim 1.

Out FIG. 1 of the WO 2004/038112 A1 already known an outlet fitting, according to the preamble of claim 1, of the type mentioned with a water outlet, which has a, bounded by an inner peripheral wall of the outlet fitting outlet opening, said outlet opening is provided on the outer periphery of a valve body and opens into a water-bearing inner cavity of the outlet fitting , To create a homogeneous, non-spattering and optionally also to produce a pearlescent water jet, an insert cartridge is inserted into the outlet opening of the known outlet fitting, which has a jet regulator. This insert cartridge has on the outer circumference of its cartridge housing an external thread which can be screwed into an internal thread on the outlet opening bounding the inner peripheral wall of the outlet fitting.

In order to limit the Einschraubweg and to seal the area between the Einsetzpatrone one hand and the outlet opening bounding the inner peripheral wall on the other hand, in the inflow-side, the inner cavity facing portion of the outlet opening designated as a jet regulator bridge annular shoulder or annular flange is provided.

The outlet opening and provided in it annular shoulder or annular flange are machined by machining in the fitting body of the outlet fitting. Since air and foreign body inclusions can not be completely excluded, especially in the area of accumulations of material in the fitting body, defects that form on the visible surfaces of the outlet fitting or in the sealing areas can form during machining of the fitting body. In addition, the processing of the fitting body and the production of different partial clearances in the opening cross sections of the outlet opening requires a considerable manufacturing effort. If an external thread is provided on the cartridge housing of the insert cartridge, with which the insert cartridge can be screwed directly into the internal thread provided on the inner peripheral wall surrounding the outlet opening, and if the insert cartridge can be screwed into the outlet opening of the water outlet with its entire longitudinal extent, this is often not without its consequences further understandable, whether and how the outlet fitting can be serviced or repaired in this area. In addition, the removal of an insert cartridge located completely in the outlet opening can also be difficult for a person skilled in the art without a corresponding special tool.

It has therefore already been created an outlet fitting, which has a water outlet with a substantially constant clear cross-section (see. WO 2009/052961 A1 ). The prior art outlet fitting has in the region of its water outlet on the inner peripheral side an internal thread into which an insert cartridge with an outer peripheral side provided external thread can be screwed such that the outlet end of the cartridge is practically flush with the outlet side end edge of the outlet fitting. Even with this known outlet fitting, it is often difficult for the user to understand whether and how the outlet fitting is to be maintained, in particular, without a corresponding special tool.

It has also already created a jet regulator with a jet regulator housing, in which further built-in parts are located (see. DE 10 2006 025 302 B3 ). The jet regulator housing can be inserted into a tubular mouthpiece. The jet regulator housing can be inserted into the mouthpiece of the outlet fitting by means of an axial insertion movement and can be locked in the mouthpiece by means of a catch holder. For selectively blocking and releasing the provided between the jet regulator housing and the mouthpiece latch mounting a tool-operated externally locking element is provided. However, the prior art jet regulator requires a separate and specially designed mouthpiece, which must be made separately from the outlet fitting. Due to the separate production of outlet fitting on the one hand and mouthpiece on the other hand, however, these are difficult to produce with a visually matching surface.

There is therefore in particular the task of creating a producible with little effort sanitary outlet fitting of the type mentioned above, which is characterized by easier maintenance, without sacrificing the functionality and the tightness of the outlet fitting in the region of its outlet opening are to be expected.

The solution according to the invention, according to claim 1, this object is in the outlet fitting of the type mentioned in particular that the outlet nozzle protrudes in functional position with a downstream portion of the outlet fitting that at the functional position on the outlet fitting projecting portion of the outlet nozzle at least one Werkzugangriffsfläche is provided for a rotary tool, that the tool engagement surface is formed as a two-sided key engagement surface that the insert cartridge from the downstream side of the outlet mouthpiece is inserted into this up to an insertion stop, and that the outlet mouthpiece carries on its inner circumference an internal thread, in which a on the outer periphery of Cartridge housing the Einsetzpatrone provided external thread can be screwed.

The outlet fitting according to the invention is associated with a sleeve-shaped outlet mouthpiece, which carries on its outer peripheral wall an external thread, with which the outlet mouthpiece can be screwed into an internal thread, which is provided at the outlet opening of the water outlet delimiting inner peripheral wall of the outlet fitting. For fastening the outlet nozzle on the inner peripheral wall of the outlet fitting so a screw is provided. Since the outlet mouthpiece with projecting a downstream portion of the outlet fitting, the interchangeability of the cartridge held in the outlet nozzle and the manner of the required for their disassembly handles occurs clearly. Since at least one tool engagement surface for a rotary tool is provided on the part of the outlet nozzle protruding beyond the outlet fitting, and since the tool engagement surface is designed as a two-sided key engagement surface, the handling of the outlet fitting according to the invention during assembly and disassembly of the outlet nozzle associated therewith is additionally made substantially easier. The outlet mouthpiece into which the insertion cartridge having a jet regulator can be screwed carries on its outer circumferential wall at least one sealing ring which radially and / or axially seals between the outer circumferential wall of the outlet nozzle and the inner circumferential wall of the outlet fitting. Since the outlet mouthpiece is radially and / or axially sealed with respect to the inner circumferential wall of the outlet fitting surrounding the outlet opening, the outlet opening can also be worked into the outlet fitting with a constant clear inside diameter. Since it is thus possible to dispense with an annular flange or annular shoulder on the inner circumferential wall required for the axial sealing in the outlet fitting according to the invention, the expense associated with the production of the outlet fitting according to the invention is substantially reduced in this area. The insert cartridge is held by means of the outlet nozzle in the water outlet of the outlet fitting according to the invention, which makes the interchangeability of Einsetzpatrone clearly and understandably come to light. Since the outlet mouthpiece with respect to the outlet fitting by means of at least one sealing ring is axially and / or radially sealed, an excessive tightening of the outlet nozzle in the outlet opening is not required and not to be feared how otherwise it is often mistakenly considered necessary for these components.

According to the invention it is provided that the insert cartridge from the downstream side of the outlet mouthpiece is inserted into this up to an insertion stop. In this case, the insertion stop provided on the outlet mouthpiece can be designed as an annular shoulder or annular flange arranged on the inner periphery of the outlet mouthpiece. In order to hold the cartridge axially secured in the outlet nozzle, the invention provides that the outlet nozzle carries on its inner circumference an internal thread into which a provided on the outer circumference of the cartridge housing external thread can be screwed.

It is a particular advantage of the outlet fitting according to the invention that it can be dispensed with the necessary for the axial sealing ring shoulder or annular flange, and that the outlet opening is to be incorporated over its entire longitudinal extent with a constant clear opening cross-section in the fitting body. A preferred embodiment according to the invention therefore provides that the outlet fitting has a fitting body which carries the outlet opening on its outer periphery and that the outlet opening has a uniform and / or paragraph-free clear opening cross-section, in particular in its end region opening into an inner cavity of the outlet fitting.

So that the sealing ring required for the radial sealing of the outlet nozzle provided according to the invention can not be inadvertently lost during storage and during transport, it is expedient if a peripheral groove is provided on the outer circumference of the outlet nozzle, in which a preferably made of elastic material Sealing ring is held. If this sealing ring is held in a circumferential groove on the outer circumference of the outlet mouthpiece, the sealing ring on the outer circumference of the outlet mouthpiece is secured in exact position.

Thus, the functional unit consisting of the outlet nozzle and insert cartridge is not accidentally lost, and thus a functional installation of this unit is always guaranteed, it is advantageous if the insert cartridge is held on both sides in the axial direction secured in the outlet nozzle. If the insert cartridge is held securely in the outlet nozzle, the functional connection with the outlet nozzle is always guaranteed.

In this case, an unclaimed embodiment provides that the insert cartridge from the inflow side of the outlet mouthpiece is inserted into this up to an insertion stop. Since, in this embodiment, the outlet nozzle is first to be dismounted from the outlet fitting before the inserter cartridge having the jet regulator can be removed from the outlet nozzle, unauthorized manipulations in this region of the outlet fitting are less to be feared in this embodiment.

In order to mount the insert cartridge on both sides in the axial direction secured in the outlet nozzle (an unclaimed embodiment), it may be advantageous if the insert cartridge between the insertion stop and a releasably secured to the inner circumference of the outlet holder holder is held in the outlet nozzle. In this case, the holder may have a retaining ring which can be deformed on its outer circumference or be designed as such, which engages in a shape-adapted groove on the inner circumference of the outlet mouthpiece.

In order to avoid false currents in the region between the insert cartridge and the inner circumference of the outlet nozzle, it may be advantageous if an annular seal is provided between the insert cartridge and the holder, which seals the area between the insert cartridge and the inner circumference of the outlet nozzle.

A preferred and particularly easy to manufacture embodiment according to the invention provides that the designed as an annular flange insertion stop is arranged in the inflow-side end plane of the outlet nozzle. If the insertion stop is arranged in the inflow-side end plane of the outlet mouthpiece, almost the entire sleeve interior of the sleeve-shaped outlet mouthpiece is available for the insertion cartridge.

A particularly simple and producible with little effort embodiment according to the invention provides that between the insert cartridge and the insert stop an annular seal is provided which seals the area between the insert cartridge and the inner circumference of the outlet nozzle axially.

However, it is also possible that at least one sealing ring is provided on the cartridge housing of the insertion cartridge, which radially and / or axially seals the area between the insertion cartridge and the inner circumference of the outlet nozzle.

Further developments according to the invention will become apparent from the claims and the description in conjunction with the drawings. The invention will be described in more detail below with reference to preferred embodiments.

In the Fig. 5 to 16 different configured outlet mouthpieces 8, 11, 14, 17 are shown. The outlet mouthpieces 8, 11, 14, 17 are designed sleeve-shaped and have on their outer peripheral wall 1 an external thread 2. The outlet mouthpieces 8, 11, 14, 17 are screwed with its external thread 2 in an internal thread 3. The internal thread 3 is provided on an inner circumferential wall 4, which delimits the outlet opening 6 of the water outlet of a sanitary outlet fitting 7.

In order to obtain a homogeneous, non-spattering and optionally also pearly-soft, i. To form aerated water jet, in the sleeve interior of the sleeve-shaped outlet mouthpieces 8, 11, 14, 17 an insert cartridge 9 can be screwed, which has a jet regulator and, if necessary, an inflow-side attachment screen 10 and / or an optionally interposed flow rate regulator.

For the outlet mouthpieces 8, 11, 14, 17 according to the Fig. 5 to 16 provided outlet fitting 7 is in the Fig. 1 and 2 shown in more detail. From the Fig. 1 and 2 It is clear that the outlet fitting 7 has a fitting body 12 which carries the outlet opening 6 on its outer periphery. While the previously known, the prior art and in the 3 and 4 have shown an outlet opening 6 ', which has in its inflow, a water-bearing inner cavity 13 facing portion of the outlet opening 6' as a jet regulator bridge annular shoulder or annular flange 15, has for the outlet mouthpieces 8, 11, 14, 17 certain outlet fitting 7 an outlet opening 6, which has a uniform and paragraph-free clear opening cross-section in their opening into the inner cavity 13 of the outlet fitting 7 end.

From a comparison of the in the Fig. 5 to 16 Outlet mouthpieces 8, 11, 14, 17 shown, it is clear that these outlet mouthpieces wear on its outer peripheral wall 1 a sealing ring 18 which seals radially and / or axially between the outer peripheral wall 1 and the inner peripheral wall 4 of the outlet fitting 7.

The outlet fitting 7 are associated with the sleeve-shaped outlet mouthpieces 8, 11, 14, 17. The outlet mouthpieces 8, 11, 14, 17 have on their outer peripheral wall 1, the external thread 2, with which the outlet mouthpieces 8, 11, 14, 17 can be screwed into the internal thread 3, which at the outlet opening 6 of the water outlet delimiting inner peripheral wall 4 of Outlet fitting 7 is provided. The outlet mouthpieces 8, 11, 14, 17, in each of which one, a jet regulator insert cartridge 9 is screwed, wear on its outer peripheral wall 1 at least one sealing ring 18, between the outer peripheral wall 1 of the outlet mouthpieces 8, 11, 14, 17 and the inner peripheral wall 4 of the outlet fitting 7 radially and / or axially seals. Since the outlet mouthpieces 8, 11, 14, 17 opposite to the outlet opening 6 bounding inner peripheral wall 4 of the outlet fitting 7 are radially and / or axially sealed, the outlet opening 6 can also be incorporated with a constant clear inner diameter in the outlet fitting 7. Since the outlet fitting 7 can thus dispense with an annular flange or annular shoulder on the inner circumferential wall 4 required for the axial sealing, the expense associated with the production of the outlet fitting 7 is substantially reduced. In this case, the Einsetzpatrone 9 is held by means of one of the outlet mouthpieces 8, 11, 14, 17 in the water outlet of the outlet fitting 7, which makes the interchangeability of this Einsetzpatrone 9 clear and understandable come to light. Since the outlet mouthpieces 8, 11, 14, 17 with respect to the outlet fitting 7 by means of at least one sealing ring 18 are at least radially sealed, an excessive tightening of the outlet nozzle in the outlet opening is not required and not to fear, as is the case with an axial seal Often these components are wrongly considered necessary.

The in the Fig. 5 to 16 shown outlet mouthpieces have on their outer circumference a circumferential groove 19 in which the sealing ring 18 made of elastic material is securely held. The insertion cartridge 9 provided in the outlet mouthpieces 8, 11, 14, 17 is held secured there on both sides in the axial direction. In Fig. 6 It can be seen that the outlet nozzle 8 can be screwed into the internal thread 3 in the outlet opening 6 until a groove 19 bounding annular flange 26 of the outlet nozzle abuts an insertion stop 27 on the inner peripheral wall of the outlet opening 7.

In the Fig. 5 to 16 It can be seen that the outlet mouthpieces 8, 11, 14, 17 carry on their inner circumference an internal thread 28, in which a on the outer circumference of the cartridge housing the insert cartridge 9 provided external thread 29 can be screwed. In this case, the insert cartridge 9 is screwed at the outlet mouthpieces 8, 11, 14, 17 from the outflow side into the sleeve interior of these outlet mouthpieces 8, 11, 14, 17.

In the outlet mouthpieces 8, 11, 17, the Einsetzpatrone 9 from the downstream side of these outlet mouthpieces out to an insertion stop 16 can be screwed. The insertion stopper 16 is formed as a ring shoulder or annular flange disposed on the inner circumference of the outlet mouthpieces 8, 11, 17. In the Fig. 5 . 8th and 14 It can be seen that the insertion stop 16 designed as an annular flange is arranged in the inflow-side end plane of the outlet mouthpieces 8, 11, 17. While the annular flange of the outlet nozzle 11 limits only the Einschraub- or Einsetzweg, between the annular flange of the outlet mouthpieces 8, 17, a sealing ring 40 is provided which seals the area between the outer periphery of the outlet mouthpieces 8, 17 and the inner peripheral wall of the outlet nozzle 8, 17 axially.

Upon closer inspection of the FIGS. 8 and 11 It is clear that on the outer circumference of the Einsetzpatrone 9 an insertion stop 16 'may be provided which is formed as an annular shoulder or annular flange and is connected upstream of the sealing ring 30 in the flow direction. This insertion stop 16 'is preferably connected downstream of the external thread 29 in the flow direction.

In the outlet mouthpieces 8, 17, the area between the insert cartridge 9 and the inner peripheral wall of the outlet nozzle 8, 17 is axially sealed by means of the sealing ring 40, which is clamped between the insertion stop 16 and the upstream end side of the cartridge housing. In contrast, this area is radially sealed at the outlet mouthpieces 11, 14 by means of a sealing ring 30, which is held on the outer circumference of the cartridge housing and arranged there in a circumferential groove 31.

From a comparison of Fig. 5 to 16 It can be seen that the outlet mouthpieces 8, 11, 14, 17 protrude with an outflow-side subregion of their longitudinal extent via the outlet fitting 7. In this case, at least one tool engagement surface 32 for a rotary tool is provided on the part of the outlet mouthpieces 8, 11, 14, 17 projecting beyond the outlet fitting. This tool engagement surface 32 is formed at the outlet mouthpieces 8, 11, 14, 17 arranged on opposite circumferential sides of the outlet mouthpiece key engagement surface.

The outlet mouthpieces 8, 11, 14, 17 have on their outer circumference on a Einsteckanschlag 33, which is designed as an annular flange or annular shoulder and the Einschraubweg the outlet mouthpieces 8, 11, 14, 17 limited in the internal thread 3. The outlet mouthpieces 8, 11, 14, 17 are screwed into the internal thread 3 of the outlet opening 6 until the plug-in stop 33 abuts against the outer edge of the outlet fitting 7 bounding the outlet opening 6. While the sealing ring 18 is held at the outlet fitting 14 in the groove 19, which adjoins the downstream Einsteckanschlag 33, the sealing ring 18 is pushed at the outlet mouthpiece 17 only to the Einsteckanschlag 33.

Even with the outlet mouthpieces 14, 17 seal the sealing rings 18 at least radially. In this case, the sealing ring 18 of the outlet nozzle 17 is pressed into a chamfer, the outflow opening 6 of the outlet nozzle 17 associated outlet fitting 7 downstream defines, so that a radial and axial Sealing effect occurs.
