Description

TITLE FLUSH VALVE ASSEMBLY

TECHNICAL AREA

The present invention relates to a flush valve arrangement for controlling the removal of water from a cistern according to the preamble of claim 1.

STATE OF THE ART

Spülventilanordnungen for controlling the removal of water from a cistern are known from the prior art.

Over time, the cisterns became more and more compact, requiring modifications to the flush valves. In particular, the flush valves have been modified for easy installation in the cistern.

The more compact design of the cisterns has the disadvantage that the flush valves for the installer in the installed state are not fully accessible. That is, during installation or maintenance, the installer can not reach all areas of the cistern with his hand. As a result, parts of the purge valve can not or only with difficulty be removed from the cistern.

PRESENTATION OF THE INVENTION

Based on this problem, the invention has for its object to provide a Spülventilanordnung, which overcomes the disadvantages of the prior art. In particular, the Spülventilanordnung should be designed such that it can be easily installed in the cistern and again removed from the cistern. Accordingly, a flushing valve arrangement comprises a flushing valve comprising a housing having a lower end and an upper end and a housing movably mounted along a central axis valve body, a Spülventilhalterung with a receiving portion for receiving the lower end of the flushing valve and a storage portion for connecting the Spülventilhalterung with a drain opening of a cistern, and a hold-down unit. With the hold-down unit, the flushing valve is held in the interior of the cistern, in particular against a buoyancy force. The hold-down unit comprises a first hold-down device acting on the housing of the flushing valve with an active section and a second hold-down device acting on the flushing valve holder with an active section.

The separate design of the two hold-downs has the advantage that the flush valve can be installed or removed separately from the Spülventilhalterung in the cistern.

The installation is also easier, because first the Spülventilhalterung and then the flushing valve can be inserted into the cistern. Especially in the tight spaces in the cistern that is an advantage.

Further, in case of maintenance, for example, only the purge valve can be removed while the purge valve holder remains in the cistern. Typically, there is a seal between the purge valve retainer and the drain port. In this respect, the separation here has the advantage that the Spülventilhalterung remains in an exchange or revision of the purge valve in the cistern, whereby the seal is not loaded. Such loads negatively affect the sealing effect.

The two hold-downs are formed separately from each other and can be connected to one another at a connection point. This connection is such that it can be canceled in case of maintenance, so that the flushing valve is removable, while the Spülventilhalterung remains in the cistern. Furthermore, at least one of the two down holders can be connected to the cistern. This connection is such that it can be canceled in case of maintenance, so that the Spülventilhalterung and the purge valve is expandable.

Preferably, the two down holders can be connected to one another via a connection point. The joint is preferably located in an easily accessible location so that the installer has good access to the joint. The connection point is preferably designed such that it can be releasably connected to the cistern.

Preferably, the joint is closer to the top of the housing along the central axis than the purge valve retainer. Alternatively, the joint is above the upper end of the housing. This arrangement has the advantage that the connection point can be arranged near a maintenance opening in the cistern. This means that the connection point is easily accessible through the maintenance opening. The maintenance opening is the opening, which is typically behind an actuator plate.

The effective sections of the hold-down devices preferably act as close as possible to the bearing section of the flushing valve holder, in particular in the region of the receiving section, on the flushing valve and the flushing valve holder. This means that the force is applied as close as possible to the point at which the Spülventilhalterung communicates with the cistern. As a result, lateral forces on the Spülventilhalterung and the purge valve can be largely avoided. As a result, the flush valve is not pushed away laterally. In addition, the guide lengths between the Spülventilhalterung and the drain opening and between the Spülventilhalterung and the purge valve can be reduced.

Preferably, the joint between the two hold-downs is provided by a snap connection between the first hold-down and the second hold-down.

The elements which provide the snap connection are firmly formed on the respective hold-down. The snap connection is preferably a direct connection between the two downholders. That means there are no others Elements between the two downholders available.

Particularly preferably, the snap connection has flexible snapper and a receptacle. The snapper engage in the receptacle, which is preferably rigid. The flexible snapper are preferably on the first hold-down and the receptacle is preferably arranged on the second hold-down.

Preferably, the hold-downs extend substantially rod-like, in particular with a rectangular cross-section, in the direction of the central axis. The joint is preferably placed at the free ends of the hold-downs. The free ends are opposite of the active sections.

That is, the hold downs are pulled upwards by the bar-like sections along the housing, which, as mentioned, is conducive to accessibility.

The hold-down devices are preferably sprung. This means that the hold-downs can be moved towards the housing and slightly away from the housing. Preferably, the two hold-downs extend substantially parallel to one another, wherein the first hold-down device is closer to the housing than the second hold-down device. Preferably, the two downholders are close to the housing, which is advantageous for the compactness of the arrangement. Preferably, at least one of the hold-down, in particular the second hold-down, a latching structure, with which the hold-down is connected to a cistern, wherein the latching structure is preferably closer to the junction than in Spülventilhalterung or wherein the latching structure in the region of the free end of the blank holder or wherein the latching structure is at the height of the connection point.

About the latching structure is the said, in particular the second, hold-down with the cistern in conjunction, while the other, in particular the first, hold-down with the said, in particular with the second, hold-down preferably over the Junction communicates.

The arrangement of the latching structure in the region of the connection point has the advantage that the latching structure is likewise easily accessible.

Preferably, at least one of the hold-down, in particular the second hold-down, between the active portion and the connection point on a compensating element, with which position tolerances compared to the cistern are compensated. The compensation element is preferably arranged in the region of the rod-like section and ensures that the rod-like section can compensate for angle errors.

Preferably, the active portion of the second hold-down and the counterpart to the Spülventilhalterung as a mechanical connection, in particular as a latching connection formed. The connection is such that the second hold-down with the Spülventilhalterung can form a solid connection. This means that the second hold-down can be firmly connected via the mechanical connection or the locking connection with the Spülventilhalterung. This allows the Spülventilhalterung be used with the hold-down in the cistern. The installer can grasp the hold down assembly and purge valve holder on the hold down and then insert the purge valve holder into the drain opening through the service opening.

In another embodiment, it is also conceivable that the effective range of the second hold-down is integrally formed on the Spülventilhalterung. This results in the same advantages as in the locking connection.

Preferably, the relative arrangement between the second hold-down and the Spülventilhalterung is such that a force in the direction of the central axis evenly applied to the Spülventilhalterung or that a force in the direction of the central axis at two with respect to the central axis substantially opposite locations on the Spülventilhalterung can be applied , This can prevent the Spülventilhalterung tilted when inserted into the drain opening. Preferably, the connection between the second hold down and the purge valve support allows for angular relative movement between the hold down and the purge valve support. As a result, tilting during assembly can be avoided. With regard to the latching connection, it is particularly preferred that two latching connections substantially opposite one another are arranged with respect to the central axis.

Preferably, the latching connection comprises a latching opening and a locking tab projecting into the latching opening.

Preferably, the active portion of the first hold-down comprises at least one spring portion which acts on an edge region of the housing. Due to the sprung training forces that can occur during rinsing can be advantageously introduced into the hold-down.

Preferably, the spring portion has the shape of a leaf spring.

Preferably, the edge region of the housing is a web projecting from the housing, the upper side of which is in contact with the hold-down device and whose underside rests on the flushing valve holder, wherein the web between the underside and upper side is preferably 5 millimeters thick. As a result, the introduction of the force in the region of the lower end can be achieved.

Preferably, the first hold-down is movably mounted in a longitudinal guide on the outside of the housing. The longitudinal guide is oriented in the direction of the central axis.

A cistern assembly comprises a cistern with a drain opening and a receptacle, with which one of the hold-down is connectable, and a Spülventilventilanordnung as described above. The Spülventilhalterung is stored in the drain opening. Preferably, the second hold-down is with its latching structure with the cistern in combination. A method of assembling a flushing valve arrangement as described above is characterized in that

that in a first step the Spülventilhalterung is mounted with the second hold-down in the cistern,

that in a subsequent step, the flush valve is mounted with the first hold-down in the receptacle of the Spülventilhalterung;

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figures, a purge valve assembly 1 for controlling the water extraction is made a cistern 29 shown. The purge valve assembly 1 essentially comprises a purge valve 2, a purge valve holder 7 and a hold-down unit 10.

The flush valve 2 essentially comprises a housing 3 with a lower end 4 and an upper end 5 and a valve body 6 movably mounted in the housing 2 along a central axis M. The valve body 6 can be characterized by a closed position in which no water from the Cistern can be removed, in a rinse, in which water can flow out of the cistern 29, move. The Spülventilhalterung 7 serves to support or storage of the purge valve 2 in the cistern 29. The Spülventilhalterung 7 thereby comprises a receiving portion 8 for receiving the lower end 4 of the purge valve 2. The lower end 4 and the receiving portion 8 are each cylindrical in the embodiment shown and the lower end 4 can be inserted into the receiving portion 8. Furthermore, the flush valve holder 7 comprises a bearing section 9 for connecting the flush valve holder 7 to a drain opening 31. The bearing section 9 protrudes into the drain opening 31. The drainage opening 31 is, as shown in FIG. 2, part of the cistern 29. The flushing valve 2 experiences a buoyancy in the water when the cistern 29 is filled with water. Against this buoyancy force acts hold-down unit 10, which keeps the purge valve 2 and the Spülventilhalterung 7 against the buoyancy force in the correct position. The holding-down unit 10 comprises a first holding-down device 12 and a second holding-down device 14. The first holding-down device 12 acts on the flushing valve 2 with an active section 11 and the second holding-down device 14 acts with an active section 13 on the flushing valve holder 7. 13, the purge valve 2 and the Spülventilhalterung 7 is held in its installed position. The hold-down unit 10 is in the embodiment shown further with the cistern 29 in connection. The two down holders 12, 14 are connectable to one another in the embodiment shown at a connection point 15. The connection is formed separable. In FIGS. 1, 3 and 4, the two hold-downs 12, 14 are connected to one another at the connection point 15. In Figures 2, 5 and 6 are the Hold-down 12, 14 separated from each other.

As shown in FIG. 1, the connection point 15 is arranged above the upper end 5 of the housing 3 as seen along the central axis M. This has the advantage that the connection point 15 in the installed state is easily accessible in the cistern by a maintenance opening not specifically shown in the figures. In FIG. 1, the approximate position of the maintenance opening is represented schematically by an ellipse 32. The maintenance opening in a cistern is typically above the maximum level of the cistern 29. In other, not shown embodiments, the junction may also be below the upper end 5 of the housing 3. However, it is advantageous that the connection point 15 seen along the central axis M, closer to the upper end 5 of the housing 3 is located as in the Spülventilhalterung 7 or that the joint 15 as seen along the central axis M seen from the lower end 4 as far as possible to lower end 4 lies.

The effective portions 1 1, 13 of the hold-down 12, 14 act as close to the bearing portion 9, in particular in the region of the receiving portion 8 on the purge valve 2 and the Spülventilhalterung 7 a. That is, the effective portions 11, 13 act as close to the drain opening 31 on the purge valve 2 and the Spülventilhalterung 7 a. This has the advantage that during assembly or during operation, the forces act as possible in the region of the corresponding guides.

For the first hold-down 12 with its active portion 1 1 means this action that it acts on the flush valve 2 slightly above the junction between the lower end 4 and the receiving portion 8. The area of action is provided in FIGS. 2 and 7 with the reference numeral 12 '. By this force, the guide length between the lower end 4 and the receiving portion 8 can be formed comparatively short, whereby the flush valve 2 can be made compact. In addition, the force is optimal because tilting between the purge valve 2 and the Spülventilhalterung 7 can be avoided.

With respect to the second hold-down 14 and its active portion 13, which acts on the Spülventilhalterung 7, this Einwirkstelle is also in the recording 30 arranged. The area of action is provided in FIG. 2 with the reference numeral 14 '. Again, tilting between the bearing portion 9 and the drain opening 31 is prevented. FIG. 2 shows the flushing valve arrangement 1 in connection with the cistern 29. The cistern 29 is shown only partially. In the figure 2, the Spülventilhalterung 7 is inserted with its bearing portion 9 in the drain opening 31 of the cistern 29. The second hold-down 14 acts with its active portion 13 on the Spülventilhalterung 7 a. Next, the second hold-down 14 via a latching structure 19 with the cistern 20 in connection. The latching structure 19 is arranged at the free end 18 of the second hold-down 14 and engages in a receptacle 30 which is molded or attached to the cistern 29, a. Between the latching structure 19 and the receptacle 30, a latching connection is provided. Next, the second hold-down 14 between the active portion 13 and the connection point on a compensation element 21. The compensation element 21 serves to compensate for positional tolerances relative to the cistern 29. For example, the compensation element 21 can compensate for an angular error. In addition, the compensation element 21 acts slightly resilient in the direction of the central axis M. Further, the compensating element 21 act as a support with the wall 20 of the cistern 29. For this purpose, the compensation element 21 in the embodiment shown on two support points 37.

In the embodiment shown, the first hold-down 12 is movably mounted in a longitudinal guide 27 on the outside of the housing 3. The longitudinal guide 27 is located close to the point at which the active portion 11 acts on the housing 3. By the storage in the longitudinal guide 27 is achieved that the first hold-down 12 forms a unit with the purge valve 2, which is then used together in the cistern. Starting from the figure 2 then the flush valve 2 can be used together with the first hold-down 12 through the maintenance opening in the cistern. In this case, the lower end 4 is inserted into the receiving portion 8 of the Spülventilhalterung 7. The housing 3 rests with an edge region 25 on the flush valve holder 7. After the successful placement of the purge valve 2, the two down holders 12, 14 can be connected to each other at the connection point 15. This connection is shown in FIG.

The second hold-down 14 is, as already mentioned, in connection with the cistern 29 and the first hold-down 12 is connected via the connection point 15 with the second hold-down 14 in connection. Thus, the first hold-down 12 is indirectly via the second hold-down 14 with the cistern 29 in conjunction.

FIG. 3 shows a further view of the flushing valve arrangement 1. From the figure 3 can be well recognized that the two hold-down 12, 14 are formed substantially rod-like and from the contact point at which the active portions 1 1, 13 act on the corresponding elements extend along the central axis M upwards. The rod-like portions have a rectangular cross-section and bear the reference numeral 40. Further, the rod-like portions 40 in the embodiment shown reinforcing ribs 41, which increases the compressive stiffness of the rod-like portion 40.

The hold-down 12, 14 are also slightly resilient, so that a kind of bending movement in the direction of arrow B is possible. By this bending movement, a tolerance compensation to the cistern 29 can be achieved.

From the figure 3 can also be well recognized that the two hold-down 12, 14 extend substantially parallel to each other. In this case, the first hold-down 12 is closer to the housing 3 than the second hold-down 14. By this arrangement, a compact structure can be created.

The connection point 15 is, as shown in the figures, in particular in Figures 1 - 3, provided by a snap connection. The snap connection is between the first hold-down 12 and the second hold-down 14 such that the two hold-down 12, 14 can be snapped together. The compound is detachable. The snap connection comprises in the embodiment shown two flexible snapper 16, which are arranged at the free end 17 of the first hold-12. Furthermore, the snap connection comprises a receptacle 38 which is arranged at the free end 18 of the second hold-down 14. The snapper 16 engage in the receptacle 38 a. The receptacle 38 is preferably rigid. Behind the receptacle 38 then has the second hold-down 14 on the locking elements 19, with which the second hold-down 14, as mentioned above, can engage in the receptacle 30 of the cistern 29.

Preferably, the snapper 16 on the outside grooves 39, which signal to the user that the snapper 16 for disconnecting the connection between the two downholders 12, 14 are to be taken. The action of the effective section 13 of the second blank holder 14 on the flush valve holder 7 will now be explained with reference to FIGS. 1 to 4 and 7. The active section 13 of the second hold-down 14 and the counterpart to the flush mount 7 are formed as a mechanical connection, in particular as a latching connection 22, 23. The mechanical connection is such that the second hold-down 14 with the Spülventilhalterung 7 can enter into a solid connection. In this way, when inserting the Spülventilhalterung 7 in the drain opening 31 of the second hold-down 14 serve as an assembly aid. In this case, the installer can grasp the free end 18 of the second hold-down 14 and insert the flushing valve holder 7 into the drainage opening 31.

The relative arrangement between the second hold-down 14 and the Spülventilhalterung 7 is such that a force F in the direction of the central axis M evenly on the Spülventilhalterung 7 can be applied. Thus, a tilting of the Spülventilhalterung 7 when inserting into the drain port 31 can be prevented. In the embodiment shown, substantially two opposite latching connections 22, 23 are arranged with respect to the central axis M. This means that a uniform distribution of the force is achieved. The latching connection 22, 23 comprise in the embodiment shown a latching opening 23 and a latching opening 22 projecting into the latching opening 23. The latching opening 23 is formed on the outside at the level of the receiving section 8 on the flushing valve holder 7, while the latching tab 22 protrudes from the second downholder 17 , In the illustrated embodiment, the locking tab 22 is of a cross member 33 which extends laterally from the rod-like portion of the second blank holder 14. Preferably, the connection between the second hold-down 14 and second Spülventilhalterung 7 such that an angular relative movement between the hold-14 and the Spülventilhalterung 7 is made possible. For this purpose, in the embodiment shown, the latching opening 23 angled at an angle to the central axis M surface 34. At a pressure in the direction of the force F, the cross member 33 can move against the surface 34. As a result, an angle error can be compensated. The angled inclined surface is particularly clearly visible in FIG. With reference to FIGS. 5 to 7, the action of the effective section 11 of the first hold-down 12 on the flushing valve 2 will now be explained in more detail. The active section 11 of the first hold-down 12 has at least one spring section 24, which acts on an edge region 25 of the housing 3. In the embodiment shown, there are two spring sections 24 which extend laterally away from the first hold-down 12 and act on the edge region 25 of the housing 3 at two spaced-apart locations. Due to the sprung training tensile forces acting on the purge valve 2 can be compensated. The spring section 24 has the form of a leaf spring in the embodiment shown. In the embodiment shown, the edge region 25 of the housing 2 is a web projecting from the housing 3, the upper side 26 of which comes into contact with the hold-down 12 or with the active section 11. The underside of the web rests on the Spülventilhalterung 7. The web has a small thickness and is preferably less than 5 millimeters thick. This means that the action of the force on the active section 1 1 is as close as possible to the Spülventilhalterung 7. The Spülventilhalterung 7 has in the embodiment shown below the receiving portion 8 to a passage region 35, through which water of the discharge port 31 can be fed. The passage region 35 in this case connects the receiving section 8 to the bearing section 9. Furthermore, a seal 36 is arranged on the outside in the region of the bearing section 9. The seal 36 seals the gap between the drain opening 31 and the outside 28 of the bearing section 9. LIST OF REFERENCE NUMBERS
