Abstract

The outlet has a conduit, provided at a discharge end, including a perforated plate and/or a grid structure or lamellar structure with a number of discharge holes or discharge openings that are bordered by conduit walls. 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 guidance downstream, which flow guide has at least one perforated plate or a grid structure with a number of outlet holes or outlet openings, wherein the water outlet comprises a spherical-shaped joint sleeve which is arranged adjustable or pivotable in a complementary shaped joint socket and wherein the flow guide is provided in the sleeve interior of the joint sleeve.

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. In this case, one has already created aerator, the downstream have a flow straightener, which is intended to align the individual beams generated in the jet controller approximately coaxially to each other and is designed for example as a perforated plate or as a grid or lamellar structure.

Often there is the problem that in the outlet fitting inflowing water flow in the region of the water outlet is to deflect 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.

From the EP-A-0 190 965 is already a sanitary water outlet of the type mentioned above known. The previously known water outlet has at its outlet end a joint socket into which a spherical layer-shaped joint sleeve can be inserted. In the sleeve interior of the joint sleeve of the one sleeve end of a ventilated jet regulator can be used. In order to use the jet regulator in the joint sleeve, the joint sleeve is rotated in the socket of the water outlet so that the imaginary as the inflow side sleeve end of the joint sleeve forms the downstream side of the water outlet; If the jet regulator is inserted into the joint sleeve, the joint sleeve is rotated again by 180 degrees, so that the inflow side of the joint sleeve and the jet regulator detachably inserted therein are intended to face the water inlet. The disadvantage, however, is that the integrated socket in the water outlet a specially designed outlet fitting requires. In addition, the free pivoting of the joint sleeve in the socket of the known water outlet difficult for the inexperienced users to position the joint sleeve and the jet regulator used therein such that the exiting water jet is not affected by the outlet opening of the water outlet bordering the edge region of the valve.

From the DE 12 90 498 B One knows already designed as a tub filling spout outlet fitting, which carries a ball joint in the area 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 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 secured against rotation, 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-and-socket ball is pivotally mounted relative to this during rotation of the handle by means of a provided between the handle and the outlet end control slot control pin guide in such a way that the outlet direction of the guided through the hollow ball joint ball water flow can be changed if necessary by turning the handle.

This motion gear-like translation of an applied by the operator rotational movement 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, the very large space requirement appears to be disadvantageous, which visually never let the solution of the problem, namely pivoting of the discharge jet in the background. Finally, the previously known outlet fitting must be specially designed with the fitting outlet described above, so that the fitting outlet can not be 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 roller-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. However, since the cylindrical jet regulator is only rotatably mounted in the valve outlet in one plane, the possibilities for optimizing the jet 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 outside 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, the water outlet according to the invention even subsequently used in conjunction with an existing outlet fitting should be.

The achievement of this object in the sanitary water spout of the type mentioned is that the socket is provided at the downstream Stirnendbereich the water outlet in a, on a sanitary water outlet fitting downstream mountable screw-in or in a jet regulator housing, that the flow guide configured as a perforated plate or as a grid structure has a number of outlet holes or outlet openings bounded by flow guide walls, and in that the pivoting movement of the hinge sleeve in the socket is limited by a pivoting stop formed by the downstream side of an upstream sanitary fitting.

The water outlet according to the invention has a joint sleeve, which is arranged to be adjustable or pivotable in a joint socket. In the sleeve interior of this joint sleeve, a flow guide is provided which has at least one perforated plate and / or a grid or lamellar structure. This at least one perforated plate or lattice structure has a number of outlet holes or outlet openings, which are delimited by flow guide walls. Due to the spherical layer shape of the joint sleeve this can be configured with a comparatively small longitudinal extent. It has surprisingly been found that such a flow guide is capable of deflecting the water even in a relatively 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.

According to the invention, it is provided that the joint socket is provided at the downstream end region of the water outlet in a screw-in sleeve which can be mounted downstream on a sanitary water outlet fitting or in a jet regulator housing. By screwing such a screw-in sleeve or by inserting such a jet regulator in the outlet mouthpiece of a conventional sanitary water outlet fitting also an alignment of the water flowing out of the water outlet is still possible without a space-consuming and possibly aesthetically disturbing ball joint would be necessary.

Thus, the joint sleeve always covers the clear cross-section of the complementarily shaped socket, and thus the water flowing through completely through the flow guide, the invention provides that the pivoting movement of the joint sleeve is limited in the joint socket by a pivot stop, by the downstream side of an upstream sanitary fixture is formed.

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

A particularly advantageous embodiment according to the invention provides that the outlet holes or outlet openings of at least one perforated plate are hexagonal or honeycomb-like and are arranged like a honeycomb to each other.

If necessary, it may be advantageous if the socket or joint sleeve is preceded by a front screen in the flow direction. In this case, a front screen can be upstream in order to avoid clogging of the flow guide by the possibly entrained in the water dirt particles.

A particularly simple and advantageous embodiment according to the invention provides that the pivot stop by the outflow side of a designed as a sanitary fitting Attachment screen, Strahlformsiebes or Strahlzerlegers is formed.

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 found in a simple manner when the latching projections engage in the locking groove. The latching resistance can be easily overcome during pivoting of the joint sleeve, wherein the remaining during pivoting in the locking groove latching 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 by means of a arranged on its inflow side restoring force in the socket held or acted upon. By this, acting on the joint sleeve restoring force the running or friction properties are improved when adjusting the pivotal position of the joint sleeve. 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 or lattice structure of the flow guide is preceded by at least one insertion or installation part which 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 of 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.

In the FIGS. 1 to 20 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 in a joint socket 3 so as to be adjustable in the manner of a ball joint or pivotable.

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 holes or 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 Figures 1 and 2 and 5 to 20 shown flow guides 4 have a polygonal and in particular a hexagonal clear opening cross-section and are arranged honeycomb-like to each other. As FIG. 3 shows, the outlet openings can also be configured by radial and concentric circumferential flow guide walls 6 circular segment. Out FIG. 4 It is clear that the outlet openings can also have a circular or - as here - quadrangular clear opening cross-section.

In FIG. 1 It can be seen that the joint socket 3 in a

Screw-in sleeve or Einschraubrosette 8 may be provided. This screw-8 is screwed into the water outlet 1 a sanitary water outlet fitting such that the screw-8 is completely submerged in the water outlet.

In FIG. 5 an outlet nozzle 9 is shown, which also carries an external thread 14 for screwing into the internal thread of a water outlet fitting. In the outlet nozzle 9 is a jet regulator housing 31 can be used, in the sleeve interior of a jet breaker insert 30 is inserted. The jet regulator housing 31 has the joint socket 3 downstream, in which the joint sleeve 2 is held adjustable or pivotable.

From the FIGS. 6 to 11 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, can on the outer circumference of the joint sleeve 2 of the FIG. 15 be shown in detail, annular circumferential locking projection 18 may be provided.

How out FIG. 11 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.

That in the FIGS. 6 and 7 shown jet regulator housing 31 has a joint socket 3, which has three spaced locking grooves 17. In these locking grooves 17, the at least one, on the ball center plane of the joint sleeve arranged latching projection 18 engage. The mutually spaced locking grooves 17 set the zero pivot position and the both sides outer pivotal positions of the joint sleeve 2.

From a comparison of FIGS. 1 . 5 and 12 to 20 It is clear that the thrust 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 (see. FIG. 1 ), a jet regulator (cf. Figures 5 . 12 to 14 and 15 to 20 ) or the like upstream sanitary fitting formed.

From a comparison of FIG. 12 on the one hand and the Figures 13 and 14 On the other hand, it is clear that the joint sleeve 2 can also be held or loaded in the joint socket 3 by means of a restoring force arranged on its inflow side. In the in the Figures 13 and 14 shown embodiments, this restoring force by a spring coil 19 (see. FIG. 14 ) or by a perforated plate 5 upstream insertion or mounting part 20 (see. FIG. 13 ), which at the same time can also be designed as a jet forming screen in order to additionally improve the beam quality. In this case, a central extension 21 is provided on the inflow side upstream beam splitter insert or the like jet regulator component, which surrounds the spring coil 19 or the spring 20 acts on the insertion or mounting part. This restoring force presses the joint sleeve 2 down into the Kalottensitz formed by the joint socket 3, whereby the running or friction properties are improved when adjusting the pivot position. By acting against the restoring force manual Umstellkraft it is possible to indemnify the joint sleeve 2 such that the frictional resistance during adjustment is minimal. Without the restoring force provided here, there is the risk that the joint sleeve 2 is pressed against the upper inner circumference of the joint socket 3, as a result of which the joint sleeve 2 can tilt slightly and make further adjustment difficult.

In addition, the restoring force acting on the joint sleeve 2 increases their friction in the joint socket 3, whereby the joint sleeve 2 additionally secured in the set position and an automatic reset is avoided, for example by the flowing water. A bias of joint sleeve 2 and socket 3 at the same time increases the sealing effect in the movement surface against disturbing water outlet. It is understood that the restoring force can also be achieved by other resilient elements and constructions.

This in FIG. 13 However, used insertion or mounting part 20 has the advantage that it additionally improves the beam quality of the water flowing through the flow guide 4. The joint sleeve may have a thickness of 1 to 15 mm. The ball-like, all-round adjustability of the joint sleeve 2 also allows the water jet always to be aligned so that it tends as little as possible for spraying when hitting a sink.

In FIG. 15 the jet regulator housing 31 of a jet regulator 10 which can be inserted into an outlet mouthpiece is shown, which has the joint socket 3 at its downstream housing end region, in which the joint sleeve 2 is mounted rotatably and pivotably. In this case, the joint sleeve 2 is pivotable only in one plane. This is by two, at its free end portion semicircular spacers 40 between Joint sleeve 3 and the overlying insertion or mounting part 20 accomplished, which is designed here as a disc or plate-shaped and provided with flow-through member 20. On the sectional view in FIG. 15 only one of the two spacers 40 can be seen. When adjusting the joint sleeve 2, the semicircular outer periphery of the two spacers 40 rolls on the plate-shaped or disk-shaped component 20 above. A movement of the joint sleeve transverse to this preferential movement is not possible, therefore, the joint sleeve 2 can be pivoted only in a plane parallel to the spacers 40 level. The preferred direction of this single pivoting plane can be carried out by the user at the fixed to the sanitary outlet fitting jet regulator by turning on a downstream and serving as a handle Verdrehsteg 42. In FIG. 15 It can be seen that this Verdrehsteg 42 has a to the pivot axis of the joint sleeve 2 approximately coaxial or axially parallel longitudinal extent. The Verdrehsteg 42 thus also serves as an indicator that indicates to the user in which axis or in which plane which is designed as a swash plate joint sleeve 2 can move. The Verdrehsteg 42 not only allows to pivot the joint sleeve 2 in the intended plane, but the rotatable in the joint socket 3 rotatably held in the circumferential joint sleeve 2 can also be rotated on Verdrehsteg 42 when the user wants to change the pivoting direction of the joint sleeve 2.

The detailed representation in FIG. 15 shows the sealing of the joint sleeve 2 relative to the joint socket 3. The penetration of these two components 2, 3 shown here does not occur in reality, but it shows the undeformed degree of joint sleeve 2 and socket 3. The illustrated penetration occurs in reality to elastic and plastic deformations, which allow a permanent seal.

This in FIG. 16 shown jet regulator housing 31 has a joint sleeve 2, which has a similar, one-sided mobility as the joint sleeve 2 in FIG. 15 Has. The two, here in alignment spacers 40 show at its free end a polygonal-shaped outer contour, which rolls on pivoting of the joint sleeve 2 about the axis perpendicular to the plane on the overlying disc or plate-shaped member 41 or the like structure. The polygonal-shaped outer contour is characterized by additional locking projections 41 or the like elevations. These locking projections 41 allow "intermediate locking positions", so that the user is signaled by various resistors when rolling this traverse that the adjustment takes place in stages. For completeness, it should be mentioned that the Zerlegerbohrungen 43 of the likewise designed as a perforated plate inflow beam splitter 44 are not here in the cutting plane, which is why only two of these Zerlegerbohrungen 43 are only partially and only hinted at.

In the FIGS. 15 and 17 to 20 It can be seen that the joint sleeve 2 has a central spacer 49, which is supported on the overlying insertion or mounting part 20. For this purpose, the insertion or installation part 20 arranged upstream on the inflow side has a spacer 50, which likewise protrudes in the form of a pin or web, so that the spacers 49, 50 act on one another at their free front ends. In this case, the upstream or downstream installation or insertion part 20 exerts a restoring force on the joint sleeve 2, which restoring force presses the joint sleeve 2 into the joint socket 3.

FIG. 17 shows a likewise designed as a pivoting jet regulator jet regulator 10 in an all-round pivoting embodiment. The enlarged detail in FIG. 17 again shows the intersection of the two corresponding and sealing components 2, 3. This overlap is a theoretical representation. In practical operation here is a biased fitting of the joint sleeve 2 to the socket 3, which ensures a high density. Because of the tightness of the measure of this Anschmiegung for the adjustment torque or for the adjustment of importance, since this adjustment should be on the one hand over all pivotal positions of the joint sleeve 2 equally easy or stiff. On the other hand, this fitting also ensures that the joint sleeve 2 as little as possible adjusted over the product life.

FIG. 18 also shows a pivotable in only one plane joint sleeve 2. The adjustment of the joint sleeve 2 of in FIG. 18 shown pivot beam controller 10 is carried out as in the above embodiments in FIGS. 15 to 17 with the flow-side Verdrehsteg 42. The difference from the previous FIGS. 15 to 17 is that the pivot axis of the joint sleeve 2 is formed by two longitudinal grooves 45 on the inner periphery of the jet regulator housing 31 and its socket 3, in which the joint sleeve 2 is mounted with pivot pin 46. To adjust the pivot plane, the joint sleeve 2 can be rotated on the downstream and outwardly projecting twisted web 42 or the housing lower part 47 of the jet regulator housing 31, which carries the joint sleeve 2 and the jet-forming perforated plate in receiving joint socket 3, is about the longitudinal axis of the jet regulator 10 is rotated. In FIG. 18 becomes clear that the zero position of the joint sleeve in shape a circumferential in the housing lower part 47 groove 48 can be realized. The joint sleeve 2 is in neutral orientation, then engages the upper free end of the elastically shaped inflow-side peripheral edge of the joint sleeve 2 in the slight undercut of the circumferential groove 48 a.

FIG. 19 shows the embodiment of a jet regulator, in which the joint sleeve 2 is movable on all sides and at the end of the end end an adjustment pin or Verdrehsteg 42 is provided so that an adjustment of the joint sleeve 2 by the user by gripping and pivoting on this Verdrehsteg 42 can take place. In addition, such a twisting bar 42 shows that it is a pivoting jet regulator 10 with an adjustable joint sleeve 2 on the outlet side, which is normally unaware to the layman, since he does not know this property so far. In addition, the direction of this Verdrehsteges 42 shown in Figure 24 then also the direction of the exiting water jet, so that with the help of this Verdrehsteges also pre-settings, without this being controlled by means of the water jet, can be performed.

In FIG. 20 a further embodiment is shown, in which the joint sleeve 2 does not run in a hollow dome-shaped socket 3, but in which the dome-shaped joint sleeve 2 is arranged in an inner cone-shaped socket.

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 in relation 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.
