TECHNICAL AREA

The present invention relates to a line piece arrangement for a sanitary article according to the preamble of claim 1.

STATE OF THE ART

Water closet basins with flushing flow restrictors are known from the prior art.

The DE 31 28 525 shows a water closet with an insert. The insert has a channel with an inlet opening and a plurality of outlet openings. The cross-section of the outlet openings can be adapted to the flushing water pressure by means of an inner part that can be inserted into the insert.

Disadvantage of the in DE 31 28 525 disclosed technical teaching is the fact that a fine adjustment of the rinse water flow is not possible.

An arrangement according to the preamble of independent claim 1 is EP2495372A1 refer to.

PRESENTATION OF THE INVENTION

Starting from this prior art, the invention is based in particular on an object of specifying a line piece arrangement, in particular for a sanitary article, which overcomes the disadvantages of the prior art. In particular, a refined throttling of the water flowing through the line piece arrangement is to be achieved.

This object is achieved by the subject matter of claim 1. Accordingly, a line piece arrangement for a sanitary article comprises a line piece extending along a central axis with a wall and with an inlet and a Outlet, and a throttle element arranged in the line piece, with which the cross section of the line piece can be changed. Water is fed to the pipe section via the inlet. The outlet opens in the direction of the sanitary article. The wall extends essentially completely around the central axis. The throttle element comprises at least one throttle web fixedly arranged in the line piece and at least one movable throttle web which is movable relative to the fixed throttle web. The throttle bars protrude into the cross-section of the line section and cause throttling.

The throttling of the water can be adjusted by moving the at least one movable throttle web relative to the fixed throttle web. With a low throttling, the movable throttle web lies above the fixed throttle web in the flow direction. The throttling can then be increased by moving the movable throttle bar relative to the fixed throttle bar.

The expression “fixed throttle web” is understood to mean that the throttle web cannot move relative to the line piece. The fixed throttle web is therefore immovably arranged in the line piece.

The expression "movable throttle web" is understood to mean that the throttle web can move relative to the line piece. The movable throttle web is therefore arranged to be movable or displaceable in the line piece.

The at least one movable throttle web is preferably pivotable relative to the at least one fixed throttle web about the central axis of the line section.

In the starting position, the at least one movable throttle web preferably lies on the at least one fixed throttle web. The throttle webs are preferably in flat contact with one another.

The at least one movable throttle web is preferably arranged upstream of the at least one fixed throttle web in the flow direction of the water. This arrangement has the advantage that parts of the movable throttle web on the fixed throttle web are supported.

Alternatively, the at least one movable throttle web is arranged in the flow direction of the water after the at least one fixed throttle web.

The at least one movable throttle web is preferably supported at least partially on the fixed throttle web. The movable throttle web is therefore in contact with the fixed throttle web over part of its extent.

In the starting position, the at least one movable throttle web is preferably above the at least one fixed throttle web, in particular exactly one above the other. In the starting position, the throttling webs lying one above the other are decisive for the throttling with regard to the throttling. To change the throttling, the at least one movable throttle web is moved relative to the at least one fixed throttle web, so that the at least one movable throttle web is offset from the at least one fixed throttle web

In the case of a plurality of movable and a plurality of fixed throttle bars, this means that in the starting position the movable throttle bars each lie above the fixed throttle bars. In the starting position, the throttling webs lying one above the other are decisive for the throttling with regard to the throttling. If the throttling changes, the movable throttle bars are shifted from their starting position with respect to the fixed throttle bars, so that at least one of the movable throttle bars lies offset from the at least one fixed throttle bar. With regard to throttling, the throttling webs which are offset from one another and, if appropriate, the throttling webs which are still one above the other are decisive.

A movable throttle web is particularly preferably assigned to each fixed throttle web.

The fixed throttle web and the movable throttle web are preferably designed in such a way that the fixed throttle web provides a greater flow resistance than the movable throttle web. As a result, the throttle effect can be further optimized by moving the movable throttle web. In this configuration, it is advantageous if the fixed throttle web is in the direction of flow in front of the movable throttle web.

In another variant, the fixed throttle web and the movable throttle web are designed such that the fixed throttle web provides a greater flow resistance than the movable throttle web.

In a further variant, the fixed throttle web and the movable throttle web are designed such that their flow resistances are the same.

The surface of the fixed throttling web facing the inlet is preferably designed as a flat surface and the surface is preferably oriented at right angles to the direction of flow.

The surface of the movable throttle web facing the inlet is preferably optimized in terms of flow technology, in particular with a curvature that is convexly curved or inclined at an angle to the direction of flow. As a result, the resistance of the movable throttle web can be optimized, in particular with respect to the fixed throttle web.

The surface of the movable throttle web facing the inlet is particularly preferably of convex curvature with a curvature, the curvature of an apex axis oriented in the direction of the throttle web being preferably identical on both sides of the apex axis. The apex axis preferably extends at right angles to the central axis.

Alternatively, the surface of the movable throttle web facing the inlet is designed as a flat surface and the surface is preferably oriented at right angles to the direction of flow.

The throttle webs, that is to say the fixed and the movable throttle web, preferably extend essentially from the center of the line section at right angles to the central axis of the line section up to the wall of the line section.

According to the invention, the fixed throttle webs are arranged exclusively in the area of one half of the line section and the movable throttle webs are arranged exclusively in the area of one half of the line section. In the case of a line section with a circular cross-section, half is defined as a circular segment with an angle of a maximum of 180 °. This design has the advantage that with maximum displacement of the movable throttle webs, uniform coverage of the entire cross-section can be created.

Preferably, at the end point of the at least one fixed throttle web or that at the intersection of the fixed throttle webs, a fixed bearing eye is arranged, which serves to support the movable throttle webs. The bearing eye is preferably essentially in the center of the line piece.

The at least one movable throttle web extends radially away from a bearing rod protruding into the bearing eye, the bearing rod being pivotally connected to the bearing eye. The at least one movable throttle web is firmly connected to the bearing rod. In particular, the at least one movable throttle web of the bearing rod is molded on.

The bearing rod preferably has an actuating section opposite the bearing eye, via which the bearing rod and the at least one movable throttle web can be pivoted relative to the at least one fixed throttle web.

Particularly preferably, several, in particular all, of the movable throttle webs are firmly connected to one another and can be moved together. All movable throttle webs are particularly preferably firmly connected to the bearing rod.

The number of movable throttle webs is preferably identical or smaller or larger than the number of fixed throttle webs, two or three or four or five or more throttle webs being preferably arranged in each case.

A plurality of fixed and a plurality of movable throttle webs are preferably arranged at the same angle to one another. The angles between the fixed throttle bars are preferred equal to the angles between the movable throttle bars.

According to the invention, two groups of at least one movable throttle web are arranged at a distance from one another in the flow direction, one of the groups above and the other of the groups below the at least one fixed throttle web, or both groups above or below the at least one fixed throttle web.

The line piece arrangement preferably further comprises at least one closure element, which can be arranged in addition to the throttle webs in contact with at least one throttle web.

One of the said closure elements can preferably be inserted at least partially into the space between two throttle webs located adjacent to one another. It is a first version of the closure element. Another of the said closure elements is preferably mounted on the actuating rod. It is a second version of the closure element.

Further throttling can be achieved with the closure elements.

The closure element is preferably designed as a separate part from the throttle web and from the line piece.

In a first variant, the at least one closure element extends over a circular sector surface, which circular sector surface is smaller than the cross section of the line piece.

At least two throttle webs are particularly preferably arranged, the closure element according to the first variant being insertable at least partially into the space between two throttle webs located adjacent to one another.

The dimensions of the circular sector area preferably correspond essentially to the space between two adjacent throttle webs, so that this space can be closed by the closure element.

The at least one closure element preferably comprises latching means with which the at least one closure element is clamped to the throttle webs. As a result, the closure element can be inserted particularly well into the intermediate space. The latching means preferably enter into a latching or clamping connection with the throttle web in the intermediate space.

As an alternative or in addition to the latching means, the closure element comprises guide pins which guide the closure element with respect to the throttle webs.

At least two of the closure elements are preferably connected to one another via a predetermined breaking point. In this way, a set can be provided and the installer can cancel the corresponding number of closure elements in accordance with the desired throttling.

In a second variant, the at least one closure element is mounted on the bearing rod. With the bearing rod, the closure element is mounted in the transverse direction to the central axis. In the longitudinal direction, the closure element is preferably supported by the throttle web.

According to the second variant, the at least one closure element extends essentially over a surface, in particular a circular surface. The area or circular area is smaller than the cross section of the line section. The closure element further comprises a bearing opening in the center for mounting the closure element on the bearing rod. The closure element can then be pushed over the bearing rod.

According to the second variant, the surface of the closure element oriented against the flow direction is preferably oriented at right angles or at an angle to the central axis. The closure element is particularly preferably frustoconical.

Particularly preferably, a plurality of closure elements according to the second variant are arranged on the bearing rod at a distance from one another in the direction of the central axis. The closure elements can also be in contact with one another.

The said plurality of closure elements particularly preferably have different diameters.

In a third variant, the first variant is combined with the second variant. Consequently, the throttle element comprises the at least one throttle web fixedly arranged in the line piece and the bearing rod protruding from the at least one throttle web in the direction of the central axis. The closure element according to the first variant is mounted on at least one throttle web and the closure element according to the second variant is mounted on the bearing rod. Reference is made to the above description with regard to the individual features of the two variants of the closure elements.

In all variants, the at least one closure element is preferably arranged in front of the throttle webs with respect to the direction of flow of the water, so that the at least one closure element is pressed against the throttle webs by the water.

In a first variant of the line section, the at least one fixed throttle web is molded onto the line section. The at least one throttle web and the line piece are thus connected to one another in one piece.

In a second variant of the line section, the line section is designed as an insert on which the at least one fixed throttle web is formed, the insert being insertable into a line.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the Figure 1 and the Figure 2 a line piece arrangement 1 is shown. The line section arrangement 1 comprises a line section 2, which extends along a central axis M, with a wall 3 and with an inlet 4 and an outlet 5. Furthermore, a throttle element 6, which also leads to the line section arrangement 1, is arranged in the line section 2. With the throttle element 6, the Cross section of the line section 2 can be changed.

The line piece 2 can be part of a line or it can be designed as an insert which can be inserted into a line. In other words, in a first variant, the line piece is an integral part of a line. In a second variant, the line piece is an insert which can be inserted into a line. The line piece is stored in the line, for example, via the outside 17 of the wall 3. The insert 3 is inserted with its wall 3 into a corresponding counterpart in a line.

The line piece 2 is preferably used in connection with sanitary articles. For example, in the flushing water line of a urinal or a toilet.

Water flows into the line section 2 via the inlet 4. In or through the line section 2, the throttle element 6 provides resistance to the water flowing through it. The water then leaves the line section 2 via the outlet 5. The outlet 5 opens out in the direction of a sanitary article, such as a toilet bowl or a urinal.

The throttle element 6, which in the Figure 1 is shown in a perspective exploded view and which in the Figure 2 is shown in the assembled position, comprises at least one fixed in the line piece 2 throttle web 7. In the embodiment shown, four fixed throttle webs 7 are arranged. The at least one fixed throttle web 7 is fixed in the line section 2. Here, the at least one fixed throttle web 7 is integrally formed on the wall 3 of the line section 2. The fixed throttle web 7 extends from the wall 3 in the direction of the interior 18 of the line section 2 essentially up to the central axis M. The fixed throttle web 7 is oriented essentially at right angles to the central axis M of the line section 2.

Furthermore, the throttle element 6 comprises at least one movable throttle web 8. In the embodiment shown, four movable throttle webs 8 are arranged. The movable throttle web is movable relative to the fixed throttle web 7. In the embodiment shown, the movement is a pivoting movement around the central axis M. Like the fixed throttle web 7, the movable throttle web 8 also projects starting from the wall 2 of the line section into the interior 18 of the line section. The movable throttle web 8 likewise extends essentially up to the central axis M and is oriented essentially at right angles to the central axis M of the line section 2.

A corresponding throttling effect is provided by protruding the two throttling webs 7, 8 into the cross section or interior 18 of the line piece 2.

A fixed bearing eye 11 is arranged at the end point of the at least one fixed throttle web 7 or at the intersection of a plurality of fixed throttle webs 7. The fixed bearing eye 11 is preferably arranged centrally in the line section 2. The bearing eye 11 is used for the movable mounting of the movable throttle webs 8. The bearing opening 19 provided by the bearing eye 11 is oriented with its central axis in the direction of the central axis M.

In the embodiment shown, the at least one movable throttle web 8 extends radially away from a bearing rod 12. The bearing rod 12 and the at least one movable throttle webs 8 are as separate parts in the Figure 1 shown. The bearing rod 12 and the at least one movable throttle web 8 can also be formed in one piece. In the connected state, the at least one movable throttle web 8 is firmly connected to the bearing rod 12. This means that when the bearing rod 12 rotates, the throttle webs 8 also move. The bearing rod 12 protrudes into the bearing opening 11 of the bearing eye 11 and is pivotally connected to the bearing eye 11 there. The bearing rod 12 can be pivoted together with the at least one movable throttle web 8 with respect to the fixed bearing eye 11.

Compared to the bearing eye 11, the bearing rod 12 in the embodiment shown further comprises an actuating section 13. The actuating section 13 here is essentially the extension of the bearing rod 12. Via the actuating section 13, the bearing rod 12 and the throttling webs 8 that are firmly connected to the bearing rod 12 can can be pivoted relative to the fixed throttle webs 7.

The movable throttle web 8 is in the embodiment according to the Figures 1 and 2 seen in the flow direction F of the water in front of the fixed throttle web 7. However, it is also possible for the movable throttle web 8 to be arranged after the fixed throttle web 7 with respect to the flow direction F.

In the shown embodiments of the Figures 1 and 2 The fixed throttle web 7 and the movable throttle web 8 are designed in such a way that the fixed throttle web 7 provides a greater flow resistance to the water flowing through the throttle element 6 than the movable throttle web 8.

The surface of the fixed throttle web 7 facing the inlet 4 is designed here as a flat surface 9, which is oriented at right angles to the flow direction F.

The surface of the movable throttle web 8 facing the inlet 4 is designed to be flow-optimized. In the embodiment shown, this surface comprises a curvature 10 which is convexly curved. Alternatively, the surface of the movable throttle web 8 facing the inlet 4 can also be designed at an angle. The curvature 10 is convex and preferably extends identically from a vertex axis S oriented in the direction of the throttle web 8 on both sides of the vertex axis S. Due to the convex curvature 10, the flow resistance of the movable throttle web 8 can be optimized accordingly and, in particular, reduced compared to the flow resistance of the fixed throttle web 7.

The number of movable throttle bars 8 is preferably identical to the number of fixed throttle bars 7. However, the number can also be different. As already mentioned, in the embodiment shown there are four fixed throttle bars 7 and four movable throttle bars 8. However, it is also conceivable to provide more than four or fewer than four throttle webs 7, 8.

The plurality of fixed throttle webs 7 are each at an equal angle α to each other. The plurality of movable throttle webs 8 are each at the same angle β to one another. Preferably, the angles α between the fixed throttle bars 7 and the angle β between the movable throttle bars 8 equal to each other. This has the advantage when adjusting the throttle element 6, that is to say when the movable throttle webs 8 are pivoted, that determined movements are possible.

In use, a sanitary installer can regulate the flush volume very finely by adjusting the throttle element 6, for example if the line piece arrangement 1 is arranged in the flush line to a toilet or a urinal. Especially in the case of so-called rimless toilet bowls or urinals, the throttling can be set in such a way that there is no excess water from the sanitary fitting.

Based on Figures 3 to 7 Various settings of the throttle element 6 will now be explained in more detail.

Of the Figures 3 to 7 it can be clearly seen that a swiveling of the movable throttle webs 8 relative to the fixed throttle webs 7 can achieve a successive reduction in the flow rate.

In the Figure 3 are all movable throttle webs 8 above a corresponding fixed throttle web 7. So a total of four throttle webs are available in cross section of the line section 2 for the throttle effect. Compared to an identical line cross-section, in which the flow rate of the volume flow is 100%, the flow rate is in Figure 3 configuration shown at about 90%.

In the Figure 4 the movable throttle webs 8 are moved one position further. Here there are three movable throttle bars 8 above three fixed throttle bars 7. A movable throttle bar 8 is no longer above a fixed throttle bar 7 and a fixed throttle bar 7 is exposed. A total of five throttle webs 7, 8 in cross section of the line section 2 are thus available for the throttling effect. Compared to the flow rate mentioned above, the flow rate here is around 85%.

In the Figure 5 the movable throttle webs 8 are moved further by a further position. Here are two movable throttle bars 8 over two fixed throttle bars 7. Two Movable throttle bars 8 are no longer above fixed throttle bars 7 and two fixed throttle bars 7 are free. A total of six throttle webs 7, 8 in cross section of the line section 2 are thus available for the throttling effect. Compared to the flow rate mentioned above, the flow rate here is around 80%.

In the Figure 6 the movable throttle webs 8 are moved further by a further position. Here, three movable throttle bars 8 are above a fixed throttle bar 7. Three movable throttle bars 8 are no longer above fixed throttle bars 7 and three fixed throttle bars 7 are exposed. A total of seven throttle webs 7, 8 in cross section of the line section 2 are thus available for the throttling effect. Compared to the flow rate mentioned above, the flow rate here is around 75%.

In the Figure 7 the movable throttle webs 8 are moved further by a further position. All movable throttle webs 8 are located here in such a way that they are no longer placed above a fixed throttle web 7. A total of eight throttle webs 7, 8 in cross section of the line section 2 are thus available for the throttling effect. Compared to the flow rate mentioned above, the flow rate here is around 70%.

In the Figures 8 to 11 the line piece arrangement 1 according to the preceding figures is shown, here the line piece arrangement 1 further comprising at least one closure element 14, 15. In the execution after the Figures 8 to 10 the closure element 14 has a different design than in the embodiment according to the Figure 11 .

The closure elements 14, 15 are arranged in addition to the throttle webs 7, 8 and come into contact with at least one of the throttle webs 7, 8.

The closure elements 14 are designed in such a way that they can be inserted partially into the intermediate space 16 of two adjacent throttle webs 7, 8.

The other of the two closure elements, namely the closure element 15 according to the Figure 11 , is mounted on the operating rod 13.

Furthermore, the throttle element 6 comprises at least one closure element 14, 15, which in Contact with the at least one throttle web 7 in the line piece 2 can be arranged to increase the throttling. The closure element 14, 15 can be designed in various ways and essentially serves to increase the cross section of the throttle element 6 in its entirety.

In the Figures 8 to 9 a first variant of the throttle element 14 is shown. In the Figure 11 a second variant of the throttle element 9 is shown. The two variants can also be combined with one another in a third variant.

In the Figures 8 to 9 a first variant of the closure element 14 is shown. The closure element 14 extends over a circular sector area. The area of the circular sector is smaller than the cross section of the line section 2. When viewed from above, the closure element 14 has the shape of a cake section.

In the embodiment shown, four throttle webs 8 are arranged, which are each at the same angular distance α. More or fewer throttle webs 8 can also be arranged. In the embodiment shown, the throttle webs 8 extend radially from a center M to the central axis M towards the wall 3. The angular distance of the throttle webs 8 also defines the space 16 between the throttle webs 8, which is to be closed by the closure element 14. In this respect, it is preferred that the angle of the area of the circular segment essentially corresponds to the angular distance α between two throttle webs 8.

In the embodiment shown, the closure elements 14 are inserted into the space between two movable throttle webs 8. It would also be conceivable for the closure elements 14 to be inserted between two fixed throttle webs 7.

On the underside, the closure element 14 according to FIG Figures 8 Locking means 20. The locking element 14 is clamped to the throttle webs 8 via these locking means 20. The locking means 20 are here essentially on the throttle webs 8. Alternatively, in an additional embodiment, a corresponding counterpart could also be molded onto the throttle webs 7.

On the underside, the closure element 8 comprises, in addition to or alternatively to the latching means 20, guide pins 21 which guide the closure element 14 with respect to the throttle webs 8.

The closure elements 14 are arranged in front of the throttle webs 8 with respect to the flow direction F, so that the closure elements 14 are pressed against the throttle web 7 by the water flowing through the line piece 2.

The closure elements 14 shown are preferably connected to one another via a predetermined breaking point 22, as is the case in FIG Figure 1 is symbolized. The installer can then cancel the desired number of closure elements 14 at the predetermined breaking point 22 accordingly. After canceling the desired number, the installer can then insert the closure elements 14 into the space 16 between the two adjacent throttle webs 7.

The closure element 14 comprises a tab 23 on the top. The tab 23 essentially serves as a grip tab, so that the closure element can be gripped easily by the installer.

In the Figure 9 a closure element 14 is arranged, while in the Figure 10 two closure elements 15 are arranged.

In the Figure 11 Another embodiment of the closure element 15 is shown. Here, the bearing rod 12 extends away from the bearing eye 11 of the throttle webs 7 in the direction of the central axis M. The at least one closure element 15 is mounted on this bearing rod 12. In the embodiment shown, the closure element 15 has the outer shape of a circular area which is smaller than the cross section of the line piece 2. In the middle, the at least one closure element 15 comprises a bearing opening 19, which serves to mount the closure element 15 on the bearing rod 12. The closure element 15 can therefore be pushed along the bearing rod 12 up to the throttle webs 7, where it rests accordingly on the throttle webs 7.

The surface 24 of the closure element 15 can be perpendicular to the central axis M be oriented. Alternatively, the surface 24, as shown in the figures, can be oriented at an angle to the central axis M, as seen in cross section, so that a kind of truncated cone results. The throttle resistance can be influenced by the formation of the surface 24.

Like in the Figure 11 shown, several closure elements 15 of different diameters can be arranged one above the other. As a result, further throttling can be achieved. Alternatively, a single closure element 15 can be arranged. The throttling effect can be changed by using the closure element 15 with different diameters. It is therefore advantageous if a plurality of closure elements 15 are present in a set and the installer then selects the closure element 15 with the desired diameter.

In a third variant, which is not shown in the figures, the closure elements 14 according to FIGS Figures 8 to 9 and the closure elements 15 according to the Figure 11 used together. It is a combined arrangement.
