A joint sleeve (2) is adjustably or pivotally arranged in a socket, such that the conduit is provided inside of the sleeve. The openings have a circular outlet cross section.

Description

The invention relates to a sanitary water outlet which has a flow guide on the outflow side, which flow guide has at least one perforated plate with a number of outlet openings which are delimited by flow guide walls, wherein the water outlet has a spherical sleeve joint sleeve, which can be pivoted in a complementarily shaped and on the downstream end region of the Water outlet is provided in an outlet mouthpiece provided joint socket, wherein the flow guide is provided in the sleeve interior of the joint sleeve, wherein the outlet nozzle on a sanitary water outlet fitting downstream can be mounted, and wherein the pivotal movement of the joint sleeve is limited in the joint socket by a pivot stop which on the inflow side of the Joint sleeve is arranged.

At the water outlet sanitary outlet fittings a jet regulator is usually provided, which is attached to the water outlet fitting by means of an outlet nozzle and should form a homogeneous, pearly-soft water jet. It has also already created aerator, the downstream one Have flow rectifier, which is intended to align the individual beams generated in the jet controller about coaxially to each other and is designed for example as a perforated plate or as a grid or lamellar structure.

There is often the problem that the flow of water flowing in the outlet fitting in the area of the water outlet is to be redirected in another direction. It has therefore also provided ball joints, which have two hingedly interconnected joint portions, of which a joint portion is connected to the water outlet of the water outlet fitting and of which the other joint portion carries the jet regulator. With the help of such a ball joint, the water jet can be aligned if necessary to the desired area. However, such ball joints have a relatively large longitudinal extent and take up a space that is not available in every application. In addition, these ball joints also change the appearance, especially in aesthetically demanding water outlet fittings. The required in known ball joints for the movement of external column also pose hygiene problems, since they are difficult or impossible to clean.

So one knows for example from the DE 12 90 498 B a Auslaufarnvatur configured as a tub filling battery, which carries a ball joint in the region of its water outlet. This ball joint has a fitting which can be mounted on the outlet fitting and which is connected in an articulated manner to a downstream outlet part. The outlet part has a downstream recess, in which optionally a commercially available jet regulator can be used. From DE 12 90 498 B previously known outlet fitting has the above described disadvantages of a ball joint.

From the DE 1 658 154 A1 already known a sanitary water spout of the type mentioned, the inner peripheral side carries at its outlet end an internal thread into which a threaded ring is screwed, which carries on its outer circumference a complementary external thread. Between this threaded ring and an inner peripheral side projecting annular flange in the water outlet, an outer peripheral side ball-zone-shaped flow guide ring is rotatably mounted, which is sealed on its outer surface by a seat tube arranged in the outlet pipe. By rotating the flow guide ring provided in the water outlet, the outflowing water jet can be aligned and, for example, aligned with the middle or the lower part of the side wall of the water jet collecting vessel to then fix the flow guide ring in the selected position by tightening the threaded ring. The out DE 1 658 154 A1 However, previously known water outlet requires a specially designed outlet fitting, which can be produced only with considerable effort.

From the pre-registered, but post-published WO 2005/093174 A2 already known a sanitary outlet fitting, at the water outlet a sleeve-shaped outlet nozzle is mounted. At the sleeve inner circumference of the outlet mouthpiece a partially spherical socket socket is provided. In the Figures 3 and 4 of the WO 2005/093174 A2 an embodiment of the pre-registered outlet fitting is shown, which carries in the socket of its outlet nozzle a Strahlbelüfter whose jet regulator housing conformed to the spherical shape of the socket and formed as a spherical zone, such that this Strahlbelüfter in the socket is rotatably mounted. Such a specially designed jet regulator not only requires a complementarily configured outlet mouthpiece, but is itself only in comparatively small quantities and with a correspondingly high cost produced. In the Figures 1 and 2 of the WO 2005/093174 A2 Therefore, an outlet fitting is shown with an outlet nozzle, in whose inner peripheral side socket a joint ball is rotatably mounted, which is penetrated by a cylindrical insertion channel into which a conventional jet regulator can be used. In this embodiment, however, is disadvantageous that the jet regulator is held in a spherical ball joint, which in turn is rotatably mounted in the spherical socket of an outlet nozzle, and therefore that the outlet nozzle has a correspondingly large outer diameter, the a special and correspondingly large inner diameter on Water outlet of the sanitary outlet fitting required.

From the DE 32 05 205 A1 One knows already a sanitary outlet fitting with a fitting outlet, which carries at its free downstream end portion a bearing surface for a ball joint ball. The bearing surface has a transverse guide slot into which a guide pin projecting axially in the ball is mounted so that it can not rotate, so that the ball joint ball can only be pivoted in one plane. The ball is held on the bearing surface by means of a handle, which is rotatably mounted on the downstream end region of the valve outlet. The ball joint ball is rotatably mounted relative to this during rotation of the handle by means of a provided between the handle piece and the outlet end control slot control pin guide in the handle so that the outlet direction of the through the hollow ball joint ball guided water stream can be changed by turning the handle as needed.

This motion gear-like translation of an applied by the operator rotation about the tube longitudinal axis in a pivoting movement of the ball member about an axis perpendicular to the tube longitudinal axis of the spout represents a motion translation, which requires a complex to produce, wear and dirt-prone kinematics. Particularly disadvantageous is also the extreme processing effort of the components and the variety of required components to see. In addition to the very large space requirement appears to be disadvantageous, which leaves the solution to the problem, namely pivoting the discharge jet, optically never in the background. Finally, the known outlet fitting must be specially designed with the above-described fitting outlet, so that the fitting outlet is not used in conjunction with an existing outlet fitting.

From the DE 19 75 191 U One already knows a sanitary outlet fitting with a fitting outlet, in which a roller-shaped jet regulator is rotatably mounted in a corresponding shape of its outlet end. This roll-shaped jet regulator has a free passage, which is arranged transversely to the longitudinal axis of the cylindrical jet regulator. In the free passage of the jet regulator beam guide ribs are provided which divide the passage into individual outlet openings. With the help of this known valve outlet, the beam direction can be adjusted even after installation of the jet regulator and change such as to fill, for example, a bathtub or similar container as quiet as possible. Since the cylindrical jet regulator but only in one Level is rotatably mounted in the valve outlet, the possibilities for optimizing the beam direction are limited.

From the EP 1 596 014 A3 already a sanitary outlet fitting with a water outlet is already known, at its front outlet end a pivotable about a pivot joint mounted jet regulator is releasably attached. The jet regulator is for this purpose in a retaining ring used, which has on its outer circumference a spherical-layer-shaped outer contour and which is pivotally mounted in a socket on the inner circumference of an outer ring, which outer ring with an outer peripheral side provided external thread in an internal thread in the water outlet can be screwed. In order to attach the jet regulator pivotable on the water outlet, are in accordance with the prior art outlet fitting EP 1 596 014 A3 the outer ring and the pivotable therein retaining ring required; In this case, outer ring and retaining ring increase the diameter in the region of the pivotable jet regulator such that the previously known pivot mechanism increases the outer diameter of the outlet fitting not insignificantly and may possibly influence the appearance of such an outlet fitting.

It is therefore an object to provide a sanitary water spout of the type mentioned above, which allows a deflection of the water jet, without a bulky and possibly aesthetically disturbing ball joint is required, in which also later still usable in conjunction with an existing outlet fitting water spout should be ensured in a simple manner that the joint sleeve always covers the clear cross section of the complementarily shaped socket and that the water flowing through completely through the flow guide.

The achievement of this object is in the water outlet of the type mentioned in particular that the pivot stop is formed by the downstream side of the joint sleeve upstream attachment screen or jet regulator.

The present subject of the invention is designed as a sanitary water outlet, which has a flow guide downstream. This flow guide has at least one perforated plate with a number of outlet openings, which are delimited by flow guide walls. The water outlet according to the invention has a spherical-layer-shaped joint sleeve, which carries the flow guide in its sleeve interior. The joint sleeve is pivotally mounted in a complementarily shaped joint socket, which is provided at the downstream end region of the water outlet in an outlet mouthpiece. It has surprisingly been found that such a flow guide is capable of redirecting the water even with a comparatively short axial longitudinal extent of the flow guide in the direction of the axial position of the flow guide walls. It can be dispensed with space-consuming and possibly aesthetically disturbing Ku-gel joints. Since the joint socket is provided in a, on a sanitary water outlet fitting downstream mounted outlet nozzle, by screwing such a component of the water outlet and an existing water outlet fitting can be changed so that now aligning the outflowing water jet is possible, if necessary, without the attachment The fitting for alignment - possibly by means of a tool - solved and must be re-attached after adjusting the water jet. By screwing such an outlet mouthpiece, the water outlet of an existing outlet fitting can be changed so that now, if necessary, an alignment of the outflowing Water jet is possible.

In order to always ensure the proper functioning of the water outlet according to the invention, it is provided that the pivotal movement of the joint sleeve is limited in the joint socket by a pivot stop, which is arranged on the inflow side of the joint sleeve and formed by the downstream side of the joint sleeve upstream attachment screen or jet regulator. In this case, a front screen can be connected upstream in order to avoid clogging of the flow guidance by the possibly entrained in the water dirt particles. With the help of a jet regulator, it is possible to form the water flowing out of the water outlet into a homogeneous, pearly-soft water jet.

To ensure that the joint sleeve always covers the clear cross section of the complementarily shaped socket, and that the water flowing through completely through the flow guide, the pivotal movement of the joint sleeve in the socket is limited by the pivot stop. The flat configuration of the water outlet according to the invention is further promoted by the fact that the pivot stop is arranged according to the invention on the inflow side of the joint sleeve and formed by the outflow side of the upstream attachment screen or jet regulator.

Preferred is an embodiment in which the outlet openings of the at least one perforated plate in the flow guide have a circular clear outlet cross-section. The flow guide walls of these circular outlet openings can be arranged comparatively close to each other and therefore able to the water jet practically over its entire beam cross-section well redirect.

Instead, it may be expedient if the outlet openings of the at least one perforated plate of the flow guide have a polygonal clear outlet cross section.

In this case, a preferred embodiment according to the invention provides that the outlet openings of at least one perforated plate are hexagonal or honeycomb-like and honeycomb-like.

In order to bring the flow guidance of the water outlet according to the invention from a pivot position in a simple manner in its original zero position, it is advantageous if the socket has at least one locking means which cooperates with at least one counter-locking means and that the latching and counter-locking means in their Detent position preferably define a zero pivot position of the joint sleeve.

It may be advantageous if the socket has a circumferential locking groove which cooperates at least with a latching projection on the outer circumference of the joint sleeve. This latching projection can rotate, for example, on the outer circumference of the joint sleeve.

However, a preferred embodiment according to the invention provides that on the outer circumference of the joint sleeve an even number of locking projections is provided, and that the locking projections are provided in pairs on opposite sides of a running through the joint sleeve center line. In this embodiment, the zero position of the joint sleeve can be on find easy way when the latching projections engage in the locking groove. The latching counter can be easily overcome during pivoting of the joint sleeve, wherein the remaining during pivoting in the locking groove locking projections advantageously form a rotary or pivot axis.

In order to press the ball-layer-shaped joint sleeve in the direction of flow in the Kalottensitz formed by the socket, it is advantageous if the joint sleeve is held or acted upon by the restoring force of a arranged on its inflow side spring coil or diaphragm spring in the socket. By this, acting on the joint sleeve restoring force are the running or friction properties when adjusting the pivotal position of the joint sleeve improved. By acting against the spring force manual Umstellkraft it is possible to indemnify the joint sleeve such that the frictional resistance during adjustment is minimal. Without such restoring force, there is the risk that the joint sleeve is pressed counter to the flow direction into the joint socket, as a result of which the joint sleeve in the joint socket can tilt slightly and make the adjustment of the joint sleeve difficult.

It is possible that the restoring force is a spring coil or a diaphragm spring, which preferably acts on the joint sleeve on its inflow-side flow side.

It is advantageous if the perforated plate and / or lattice or lamellar structure of the flow guide is preceded by at least one insertion or installation part, which is designed as a jet forming screen and / or exerts a restoring force on the joint sleeve.

Such an insertion or installation part, which is designed as a jet forming screen, can further improve the beam quality. Does this insertion or fitting additionally or instead a restoring force on the joint sleeve, the running or friction properties are improved when adjusting the pivotal position of the joint sleeve, without a special return spring would be required.

The joint sleeve is held in the complementarily shaped socket particularly safe and good when the spherical layer shape of the joint sleeve extends through a central plane of the ball.

Further features of the invention will become apparent from the following Description of an embodiment according to the invention in conjunction with the claims and the drawings. The individual features may be implemented here alone or in several embodiments in accordance with the invention.

one with FIG. 5 comparable joint sleeve, however, has an even number of, on opposite sides of the joint sleeve in pairs associated latching projections.

In the FIGS. 1 to 3 various embodiments of a sanitary water spout 1 are shown. The water outlets 1 shown here have a spherical-layer-shaped joint sleeve 2, which is arranged pivotable in a joint socket 3 in the manner of a ball joint.

In the sleeve interior of the joint sleeve 2, a flow guide 4 is provided, which has a perforated plate 5 with a number of, bounded by flow guide walls 6 outlet openings 7.

Due to the spherical layer shape of the joint sleeve 2, this can be configured with a comparatively small longitudinal extent. It has surprisingly been found that such a flow guide is capable of redirecting the water even with a comparatively short axial longitudinal extent of the flow guide in the direction of the axial position of the flow guide walls. It can be dispensed with space-consuming and possibly aesthetically disturbing ball joints.

The outlet holes in the FIGS. 1 to 3 shown flow guides 4 may have a polygonal clear opening cross-section. As FIG. 2 shows, the outlet openings can also be configured by radial and concentric circumferential flow guide walls 6 circular segment. Out FIG. 3 It is clear that the outlet openings can also have a circular or - as here - quadrangular clear opening cross-section.

In FIG. 1 an outlet nozzle 9 is shown, which can be attached to a conventional sanitary water outlet fitting. In the outlet nozzle 9 is a jet regulator 10 with upstream front screen 11 can be used, which form a homogeneous, pearly-soft water jet and also ventilate here. The outlet nozzle 9 has at its downstream Stirnendbereich a joint socket 3, in which the flow guide 4 having joint sleeve 2 is pivotally or adjustably held. It is from a comparison of FIG. 1 on the one hand and the FIGS. 2 and 3 on the other hand recognizable that on the outer circumference of the joint sleeve 2 depressions 12 or the like recesses are provided which allow air access to the jet regulator 10.

From the FIGS. 4 to 6 it can be seen that the socket 3 has at least one locking means 17 which cooperates with at least one counter-locking means 18 on the outer circumference of the joint sleeve 2. In this case, latching and counter-latching means 17, 18 in their latching position, for example, a zero-pivot position of the joint sleeve fixed. While the socket 3 here to a circumferential locking groove 17 has, may be provided on the outer circumference of the joint sleeve 2 in detail shown in Figure 15, annular circumferential locking projection 18.

How out FIG. 6 It can be seen, but it is possible that on the outer circumference of the joint sleeve 2 an even number of locking projections 18 is provided, which are respectively provided in pairs on opposite sides of a running through the hinge sleeve center line.

Out FIG. 1 becomes clear that the gift movement of the Joint sleeve 2 is limited in the joint socket 3 by a pivot stop, which is arranged on the inflow side of the joint sleeve 2. This pivot stop is here by the downstream side of a front screen or a jet regulator (see. FIG. 1 ) educated.

It is possible in all embodiments shown here to improve the seal between the joint sleeve 2 and the hollow-calotte or hollow-conical socket 3 in that the material of the socket 3 or preferably the material of the joint sleeve 2 consists of a water-absorbing and thus swellable material , In the case of operation, these components will always be wet or wet, so that compared to the mounting case, a biasing particular of the elastically pronounced sealing edge on the inflow-side peripheral edge region of the joint sleeve 2 occurs. This leads to a constant bias voltage over the entire product life and at the same time easy installation. Depending on the dimensional design and the size of the swelling, this may even lead to a desired fixation and blocking of the joint sleeve 2 in the joint socket 3 during operation.
