Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Befestigungsanordnung für ein WC-Klappelement, wie eine WC-Brille oder ein WC-Deckel nach dem Oberbegriff von Anspruch 1.The present invention relates to a fastening arrangement for a toilet folding element, such as a toilet seat or a toilet lid, according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Aus dem Stand der Technik sind verschiedene Befestigungsanordnungen für ein Klappelement bekannt geworden.Various fastening arrangements for a folding element have become known from the prior art.

Beispielsweise zeigt die WO 2016/001318 eine Befestigungsmöglichkeit eines WC-Sitzes, wobei Lagerbolzen eingesetzt werden, mit welchen ein WC-Sitz verbindbar ist. Die Lage der Lagerbolzen ist mit einer Positionierhilfe ausrichtbar, wobei nach erfolgter Ausrichtung der Ringraum zwischen Lagerbolzen und WC-Keramik mit einem Spaltenfüller ausgefüllt wird und der Lagerbolzen mit einer Mutter mechanisch fixiert wird. Die Befestigungslösung nach der WO 2016/001318 ist nachteilig, weil für die Ausrichtung des WC-Sitzes zur Toilettenschüssel eine separate Positionierhilfe eingesetzt werden muss und weil die Sicherungsmittel des Lagerbolzens schlecht zugänglich sind. Andere Lösungen verwenden Verschraubungen, wobei dort nachteilig ist, dass die Ausrichtung typischerweise sehr mühsam ist und dass eine Entfernung des Sitzrings beispielsweise bei einer Komplettreinigung sehr aufwändig ist und der Sitzring neu ausgerichtet werden muss. Ein Beispiel für eine Verschraubung ist aus der US2013/198942 bekannt.For example, the WO 2016/001318 a mounting option for a toilet seat, with bearing bolts being used, with which a toilet seat can be connected. The position of the bearing bolts can be aligned with a positioning aid, after which the annular space between the bearing bolt and the toilet bowl is filled with a gap filler and the bearing bolt is mechanically fixed with a nut. The fastening solution after the WO 2016/001318 is disadvantageous because a separate positioning aid must be used to align the toilet seat with the toilet bowl and because the securing means of the bearing bolt are difficult to access. Other solutions use screw connections, the disadvantages of which are that the alignment is typically very difficult and that removing the seat ring, for example in the case of a complete cleaning, is very complex and the seat ring has to be realigned. An example of a screw connection is from US2013/198942 known.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend vom Stand der Technik liegt der Erfindung eine Aufgabe zugrunde, ein Befestigungssystem für ein WC-Klappelement, wie ein Sitzring und/oder ein Toilettendeckel anzugeben, welches die Nachteile des Standes der Technik überwindet. Insbesondere soll ein Befestigungssystem für ein WC-Klappelement angegeben werden, mit welchem das WC-Klappelement einfacher ausrichtbar ist. Eine weitere besonders bevorzugte Aufgabe ist es, ein Befestigungssystem für ein WC-Klappelement anzugeben, mit welchem das WC-Klappelement unter der Massgabe einer einfachen Reinigung einfacher ausrichtbar ist.Based on the prior art, the invention is based on an object, a fastening system for a toilet folding element, such as a seat ring and / or Specify toilet seat, which overcomes the disadvantages of the prior art. In particular, a fastening system for a folding toilet element is to be specified, with which the folding toilet element can be aligned more easily. A further particularly preferred object is to specify a fastening system for a folding toilet element with which the folding toilet element can be aligned more easily with the proviso that it is easy to clean.

Mindestens eine der genannten Aufgabe wird durch ein Befestigungssystem gemäss Anspruch 1 gelöst.At least one of the stated tasks is solved by a fastening system according to claim 1.

Bei der Montage ist es also möglich, den Scharniersupport, insbesondere mit dem WC-Klappelement, auszurichten und anschliessend nach erfolgter Ausrichtung über die von oben zugängliche Antriebsstruktur festzuschrauben. Somit entfällt eine Ausrichtung mit einer Vorlage oder ein mehrfaches Ausrichten. Darüber hinaus ist aufgrund der Verbindung über den Lagerbolzen mit dem Scharniersupport eine einfach zu trennende Verbindung vorgesehen, so dass der Scharniersupport mit dem WC-Klappelement für die Reinigung einfach von der Toilettenschüssel getrennt werden kann.During assembly, it is therefore possible to align the hinge support, in particular with the folding toilet element, and then, after alignment has taken place, to screw it on via the drive structure that is accessible from above. This eliminates the need for alignment with a template or multiple alignments. In addition, due to the connection via the bearing pin to the hinge support, an easy-to-separate connection is provided, so that the hinge support with the toilet folding element can be easily separated from the toilet bowl for cleaning.

Die Ausdrucksweise "von oben her" ist im vorliegenden Zusammenhang so zu verstehen, dass in Einbaulage der Antriebsabschnitt von oberhalb der Auflagefläche zugänglich ist. Das heisst es kann beispielsweise ein Werkzeug in vertikaler Richtung von oben in Richtung Auflagefläche in die Antriebsstruktur bewegt werden.The expression "from above" is to be understood in the present context such that in the installed position the drive section is accessible from above the support surface. This means, for example, a tool can be moved in the vertical direction from above in the direction of the support surface in the drive structure.

Die Ausdrucksweise "Horizontal" ist so zu verstehen, dass die Auflagefläche in Einbaulage in der einer horizontal verlaufenden Ebene liegt, welche Ebene rechtwinklig zur Lotrichtung steht.The expression "horizontal" is to be understood in such a way that the bearing surface lies in a horizontally extending plane in the installed position, which plane is at right angles to the perpendicular direction.

Der Querschnitt des Aufnahmeabschnittes und der Querschnitt der Lageröffnung sind vorzugsweise derart gewählt, dass der Lagerbolzen relativ zur Lageröffnung rotierbar ist.The cross section of the receiving section and the cross section of the bearing opening are preferably selected in such a way that the bearing bolt can be rotated relative to the bearing opening.

Vorzugsweise liegt zwischen dem Anschlagsabschnitt und dem Gewindeabschnitt weiter ein Übergangsabschnitt, welcher sich in Einbaulage durch eine Befestigungsöffnung in der Toilettenschüssel hindurch erstreckt.Preferably, there is also a transition section between the stop section and the threaded section, which in the installed position extends through a fastening opening in the toilet bowl.

Die Zahl der Befestigungsöffnungen, die Zahl der Lagerbolzen und die Zahl der Lageröffnungen sind aufeinander abgestimmt und entsprechen einander.The number of fastening openings, the number of bearing bolts and the number of bearing openings are coordinated and correspond to one another.

Vorzugsweise ist die Antriebsstruktur stirnseitig am freien Ende des Aufnahmeabschnittes angeordnet. Hierdurch kann ein guter Zugang von oben her geschaffen werden. Darüber hinaus wird die Antriebsstruktur beim Blick von oben her sichtbar und kann vom Benutzer gut erkannt werden.The drive structure is preferably arranged on the front side at the free end of the receiving section. This allows good access to be created from above. In addition, the drive structure becomes visible when viewed from above and can be easily recognized by the user.

Vorzugsweise erstreckt sich die Antriebsstruktur von der Stirnseite des Aufnahmeabschnitts in den Aufnahmeabschnitt hinein. Hierdurch kann eine einfache Struktur geschaffen werden.The drive structure preferably extends from the end face of the receiving section into the receiving section. This allows a simple structure to be created.

Die Antriebsstruktur kann verschiedene Formen aufweisen, wobei die Form so gewählt ist, dass mit einem Werkzeug eine Drehung auf den Lagerbolzen übertragen werden kann. Vorzugsweise handelt es sich bei der Antriebsstruktur um einen Innenvierkant oder einen Innensechskant oder einen Schlitz oder einen Kreuzschlitz oder einen Torx. Erfindungsgemäss weist der Aufnahmeabschnitt einen konstanten Aussendurchmesser auf, wobei der Aussendurchmesser im Bereich der Antriebsstruktur keine Vergrösserung aufweist. Das heisst, die Antriebsstruktur kann sehr kompakt ausgebildet werden. Vorzugsweise ist der Durchmesser der Lageröffnung im Wesentlichen identisch zum Aussendurchmesser des Aufnahmeabschnitts. Hierdurch kann eine gute Lagerung erreicht werden.The drive structure can have different shapes, the shape being selected such that a tool can be used to transfer rotation to the bearing pin. The drive structure is preferably a square socket or a hexagon socket or a slot or a Phillips slot or a torx. According to the invention, the receiving section has a constant outside diameter, the outer diameter in the area of the drive structure not being enlarged. That is, the drive structure can be made very compact. The diameter of the bearing opening is preferably essentially identical to the outer diameter of the receiving section. This allows good storage to be achieved.

Besonders bevorzugt liegt in Einbaulage gesehen die Antriebsstruktur vollständig im Inneren der Lageröffnung. Die Antriebsstruktur ist insbesondere von oben her durch die Lageröffnung zugänglich. Das heisst ein Werkzeug kann durch die Lageröffnung zur Antriebsstruktur geführt werden. Die Lage im Inneren der Lageröffnung hat den Vorteil, dass die Antriebsstruktur von äusseren Einflüssen geschützt ist.Viewed in the installed position, the drive structure particularly preferably lies completely inside the bearing opening. The drive structure is accessible in particular from above through the bearing opening. This means that a tool can be guided through the bearing opening to the drive structure. The location inside the bearing opening has the advantage that the drive structure is protected from external influences.

Mit anderen Worten liegt das freie Ende des Aufnahmeabschnittes im Inneren der Lageröffnung und ragt nicht aus der Lageröffnung hinaus. Die Tiefe der Lageröffnung ist somit grösser als die Länge vom Aufnahmeabschnitt.In other words, the free end of the receiving section is inside the bearing opening and does not protrude out of the bearing opening. The depth of the bearing opening is thus greater than the length of the receiving section.

Auch wäre es denkbar, dass das freie Ende mit der Antriebsstruktur aus der Lageröffnung hinaus ragt.It would also be conceivable for the free end with the drive structure to protrude out of the bearing opening.

Vorzugsweise weist der Anschlagsabschnitt zur Auflagefläche der Toilettenschüssel hin eine Ringfläche auf, wobei zwischen der Ringfläche und der Auflagefläche ein elastisches Scheibenelement liegt. Das Scheibenelement weist eine Oberseite auf, die komplementär bzw. passend zur Ringfläche ausgebildet ist und die mit der Ringfläche in Kontakt steht. Weiter weist das Scheibenelement eine Unterseite auf, die auf der Auflagefläche aufliegt. Vorzugsweise ist das Scheibenelement elastisch ausgebildet.The abutment section preferably has an annular surface towards the bearing surface of the toilet bowl, with an elastic disk element lying between the annular surface and the bearing surface. The disk element has an upper surface which is designed to complement the annular surface and which is in contact with the annular surface. Furthermore, the disc element has an underside that rests on the bearing surface. The disc element is preferably designed to be elastic.

Vorzugsweise ist die besagte Ringfläche konkav gerundet und die Oberseite ist konvex gerundet. Das hat den Vorteil, dass die Lage des Lagerbolzens noch leicht variiert werden kann, was gerade im Bereich von keramischen Toilettenschüsseln ein Vorteil ist. Dadurch können Fertigungstoleranzen an der Toilettenschüssel einfach ausgeglichen werden. Alternativerweise ist die Ringfläche konvex gerundet und die Oberseite ist konkav gerundet. In beiden Varianten verläuft die Unterseite im Wesentlichen in einer Ebene.Preferably said ring surface is concavely rounded and the top is convexly rounded. This has the advantage that the position of the bearing bolt can still be easily varied, which is an advantage in the area of ceramic toilet bowls. As a result, manufacturing tolerances on the toilet bowl can be easily compensated. Alternatively, the ring surface is convexly rounded and the top is concavely rounded. In both variants, the underside essentially runs in one plane.

Die Ringfläche und die Oberseite können aber auch eben ausgebildet sein.However, the annular surface and the upper side can also be flat.

Vorzugsweise weist der Anschlagsabschnitt zum Scharniersupport hin, eine Ringfläche auf, auf welcher der Scharniersupport aufsteht. Alternativerweise steht der Scharniersupport auf der Auflagefläche auf.The stop section preferably has an annular surface towards the hinge support, on which the hinge support rests. Alternatively, the hinge support stands on the support surface.

Vorzugsweise ist das Gegengewinde Teil eines Nutensteins, welcher in einer Nutenbahn in mindestens eine Richtung mit Spiel gelagert ist. Vorzugsweise ist der Nutenstein in mehrere Richtungen mit Spiel gelagert, wobei die Lagerung vorzugsweise derart ist, dass sich der Nutenstein parallel zur Auflagefläche bewegen kann.The counter-thread is preferably part of a sliding block, which is mounted in a groove track with play in at least one direction. The sliding block is preferably mounted with play in several directions, the mounting preferably being such that the sliding block can move parallel to the support surface.

Das Spiel des Nutensteins in der Nutenbahn entspricht im Wesentlichen dem Spiel des Lagerbolzens in der Befestigungsöffnung der Toilettenschüssel. Das Spiel des Lagerbolzens in der Befestigungsöffnung wird durch einen Durchmesserunterschied zwischen dem Durchmesser der Befestigungsöffnung und dem Durchmesser der Teile des Lagerbolzens erreicht, die durch die Befestigungsöffnung hindurch ragen.The play of the sliding block in the groove track essentially corresponds to the play of the bearing bolt in the fastening opening of the toilet bowl. The play of the bearing pin in the mounting hole is achieved by a difference in diameter between the diameter of the mounting hole and the diameter of the parts of the bearing pin that protrude through the mounting hole.

Vorzugsweise ist die Nutenbahn Teil eines Rahmenelementes, welches in einem rückwärtigen Aufnahmeraum in der Toilettenschüssel gelagert ist. Das Rahmenelement kann beispielsweise Teil einer Lagerstruktur sein, mit welcher die Toilettenschüssel an einer Wand befestigbar ist. Das Rahmenelement kann aber auch anderweitig eingesetzt sein oder extra für die Aufnahme des Nutenelements im besagten rückwärtigen Aufnahmeraum gelagert sein.The grooved track is preferably part of a frame element which is mounted in a rear receiving space in the toilet bowl. The frame element can, for example, be part of a bearing structure with which the toilet bowl can be fastened to a wall. However, the frame element can also be used in another way or be mounted in the said rear receiving space especially for receiving the grooved element.

Erfindungsgemäss weist der Aufnahmeabschnitt zur Sicherung des Scharniersupports mindestens einen Federring auf, wobei der mindestens eine Federring vorzugsweise das einzige Sicherungselement zwischen Scharniersupport und Lagerbolzen ist. Dies hat den Vorteil, dass die Montage und die Demontage des Scharniersupports sehr einfach sind. Insbesondere sind keine weiteren Sicherungsmittel, wie Schrauben, Splinten oder dergleichen nötig, um den Scharniersupport zu den Lagerbolzen zu sichern.According to the invention, the receiving section for securing the hinge support has at least one spring washer, the at least one spring washer preferably being the only securing element between the hinge support and the bearing pin. This has the advantage that the assembly and disassembly of the hinge support is very easy. In particular, no further securing means such as screws, splints or the like are required to secure the hinge support to the bearing bolt.

Vorzugsweise erstreckt der Scharniersupport sich entlang einer Scharnierachse und seine Aussenform ist im Querschnitt quer zur Scharnierachse gesehen im Wesentlichen über die einem kompakten Querschnitt ausgebildet werden kann. Der Scharniersupport kann Einschnitte und Verstärkungsrippen aufweisen.Preferably, the hinge support extends along a hinge axis and its outer shape is seen in cross-section transverse to the hinge axis essentially over the a compact cross-section can be formed. The hinge support may have cuts and reinforcing ribs.

Vorzugsweise verläuft die Lageröffnung rechtwinklig zur Scharnierachse und liegt im Querschnitt gesehen im Wesentlichen mittig zum Scharniersupport.The bearing opening preferably runs at right angles to the hinge axis and, viewed in cross-section, lies essentially in the center of the hinge support.

Vorzugsweis weist der Scharniersupport jeweils stirnseitig eine Aufnahmeöffnung auf, in welcher ein Scharnierelement gelagert ist. Am Scharnierelement ist das WC-Klappelement gelagert. Bevorzugt durchdringt die Lageröffnung die Aufnahmeöffnung und das Scharnierelement erstreckt sich um den Querschnitt der Lageröffnung herum. Das heisst es gibt keine Kollision zwischen Scharnierelement und dem Lagerbolzen, der in die Lageröffnung einragt. Alternativerweise steht ein Scharnierteil stirnseitig in Richtung der Scharnierachse vom Scharniersupport ab.The hinge support preferably has a receiving opening on the front side, in which a hinge element is mounted. The toilet folding element is mounted on the hinge element. The bearing opening preferably penetrates through the receiving opening and the hinge element extends around the cross section of the bearing opening. This means that there is no collision between the hinge element and the bearing pin that protrudes into the bearing opening. Alternatively, a hinge part protrudes from the hinge support at the end face in the direction of the hinge axis.

Eine Anordnung umfasst ein Befestigungssystem nach obiger Beschreibung sowie ein am Scharniersupport verschwenkbar gelagertes WC-Klappelement, insbesondere in der Gestalt eines Sitzrings und/oder eines Deckels und eine Toilettenschüssel, an welcher das Befestigungssystem über den oder die Lagerbolzen gelagert ist.One arrangement includes a fastening system as described above and a toilet folding element pivotably mounted on the hinge support, in particular in the form of a seat ring and/or a lid and a toilet bowl on which the fastening system is mounted via the bearing bolt or bolts.

Vorzugsweise umfasst die Toilettenschüssel zwei zueinander beabstandete Durchführöffnungen, durch welche der Lagerbolzen hindurch geführt wird. Das heisst, es sind bevorzugt zwei Lagerbolzen vorhanden, welche in einem Abstand zueinander stehen.The toilet bowl preferably comprises two feed-through openings spaced apart from one another, through which the bearing bolt is guided. This means that there are preferably two bearing bolts which are at a distance from one another.

Vorzugsweise ist der Scharniersupport von einem Blendenelement überdeckt. Das Blendenelement erstreckt sich vorzugsweise über den gesamten Scharniersupport.The hinge support is preferably covered by a screen element. The screen element preferably extends over the entire hinge support.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In den Figuren wird ein Befestigungssystem 1 für ein WC-Klappelement 2 an einer Toilettenschüssel 4 gezeigt. Das WC-Klappelement 2 kann von einer in der Horizontalen H liegenden Auflagefläche 3, die Teil einer Toilettenschüssel 4 ist, weggeklappt werden. Das WC-Klappelement 2 ist typischerweise ein WC-Deckel und/oder ein WC-Sitzring.In the figures, a fastening system 1 for a toilet folding element 2 on a toilet bowl 4 is shown. The toilet folding element 2 can be folded away from a bearing surface 3 lying in the horizontal H, which is part of a toilet bowl 4 . The toilet folding element 2 is typically a toilet lid and/or a toilet seat ring.

In der Figur 1 wird eine Explosionsdarstellung gezeigt, bei welcher das WC-Klappelement 2 beabstandet von der Auflagefläche 3 gezeigt ist.In the figure 1 an exploded view is shown, in which the toilet folding element 2 is shown at a distance from the support surface 3 .

Das Befestigungssystem 1 umfasst mindestens einen sich entlang einer Mittelachse M erstreckenden Lagerbolzen 5. Hier sind zwei Lagerbolzen 5 angeordnet. In der Figur 1 wird die grundsätzliche Anordnung der beiden Lagerbolzen 5 gezeigt. Die beiden Lagerbolzen 5 liegen beabstandet zueinander. Ein Teil des Lagerbolzens 5 erstreckt sich von der Auflagefläche 3 der Toilettenschüssel 4 entlang der Mittelachse M nach oben. Die Mittelachse M ist dabei im Wesentlichen rechtwinklig zur Horizontalen H orientiert. Ein anderer Teil des Lagerbolzens erstreckt sich über eine Befestigungsöffnung 28 der Toilettenschüssel 4 in die Toilettenschüssel 4 hinein.The fastening system 1 comprises at least one bearing bolt 5 extending along a central axis M. Two bearing bolts 5 are arranged here. In the figure 1 the basic arrangement of the two bearing pins 5 is shown. The two bearing bolts 5 are spaced apart from one another. A part of the bearing bolt 5 extends upwards from the support surface 3 of the toilet bowl 4 along the central axis M. The central axis M is oriented essentially at right angles to the horizontal H. Another part of the bearing bolt extends into the toilet bowl 4 via a fastening opening 28 of the toilet bowl 4 .

Weiter umfasst das Befestigungssystem 1 einen Scharniersupport 9 zur verschwenkbaren Lagerung des WC-Klappelementes 2 an der Toilettenschüssel 4. Der Scharniersupport 9 ist mit dem mindestens einen Lagerbolzen 5 in Verbindung bringbar und wird über den mindestens einen Lagerbolzen 5 an der Toilettenschüssel 4 gelagert.The fastening system 1 also includes a hinge support 9 for the pivotable mounting of the toilet folding element 2 on the toilet bowl 4. The hinge support 9 can be connected to the at least one bearing pin 5 and is mounted on the toilet bowl 4 via the at least one bearing pin 5.

Der Lagerbolzen 5 umfasst, wie in den Figuren gezeigt, einen Aufnahmeabschnitt 6, einen sich daran anschliessenden Anschlagsabschnitt 7 und ein Gewindeabschnitt 8. In der gezeigten Ausführungsform ist der Gewindeabschnitt 8 über einen Überbrückungsabschnitt 27 dem Anschlagsabschnitt 7 angeformt. Der Aufnahmeabschnitt 6 dient der Lagerung des Scharniersupports 9. Der Anschlagsabschnitt 7 ist direkt oder indirekt mit der Auflagefläche 3 der Toilettenschüssel 4 verbindbar.As shown in the figures, the bearing bolt 5 comprises a receiving section 6, an adjoining stop section 7 and a threaded section 8. In the embodiment shown, the threaded section 8 is formed onto the stop section 7 via a bridging section 27. The receiving section 6 serves to mount the hinge support 9. The stop section 7 can be connected directly or indirectly to the bearing surface 3 of the toilet bowl 4.

In der Figur 2 wird eine Schnittdarstellung durch die Mittelachse M des Lagerbolzens 5 gezeigt. Hier kann gut erkannt werden, dass das Befestigungssystem 1 weiter ein bezüglich des Lagerbolzens 5 drehfest gelagertes Gegengewinde 11 aufweist, in welches der Lagerbolzen 5 eingreift. Der Gewindeabschnitt 8, welcher sich unterhalb des Anschlagsabschnittes 7 in Richtung der Mittelachse erstreckt, ist in den Eingriff mit dem Gegengewinde 11 bringbar. Der Gewindeabschnitt 8 ist in der gezeigten Ausführungsform ein Aussengewinde und das Gegengewinde 11 ist ein Innengewinde.In the figure 2 a sectional view through the central axis M of the bearing pin 5 is shown. It can be clearly seen here that the fastening system 1 also has a counterthread 11 which is mounted in a rotationally fixed manner with respect to the bearing pin 5 and into which the bearing pin 5 engages. The threaded section 8, which extends below the stop section 7 in the direction of the central axis, can be brought into engagement with the mating thread 11. In the embodiment shown, the threaded section 8 is an external thread and the mating thread 11 is an internal thread.

In der gezeigten Ausführungsform erstrecken sich der Aufnahmeabschnitt 6 und der Anschlagsabschnitt 7 von der Auflagefläche 3 nach oben hin weg, während sich der Gewindeabschnitt 8 bzw. der hier gezeigte Überbrückungsabschnitt 27 durch eine Befestigungsöffnung 28 in der Toilettenschüssel 4 nach unten hin zum Gegengewinde 11 erstrecken. Der Überbrückungsabschnitt 27 weist mindestens eine Länge auf, welche leicht grösser ist als die Tiefe der Befestigungsöffnung 28, wobei zudem der Durchmesser des Überbrückungsabschnittes 27 vorzugsweise kleiner ist als der Aussendurchmesser des Gewindeabschnittes 8. Der Aussendurchmesser des Überbrückungsabschnittes 27 ist kleiner als der Durchmesser der Befestigungsöffnung 28, so dass Spiel zwischen Lagerbolzen 5 und der Befestigungsöffnung 28 entsteht. Sofern sich dem Anschlagsabschnitt 7 der Gewindeabschnitt 8 direkt anschliesst, das heisst, wenn kein Überbrückungsabschnitt 27 vorhanden ist, ist der Aussendurchmesser des Gewindeabschnitts 8 kleiner als der Durchmesser der Befestigungsöffnung 28. Hierdurch wird ebenfalls Spiel geschaffen.In the embodiment shown, the receiving section 6 and the stop section 7 extend upwards away from the support surface 3, while the threaded section 8 or the bridging section 27 shown here extends downwards through a fastening opening 28 in the toilet bowl 4 to the counter-thread 11 extend. The bridging section 27 has at least a length which is slightly greater than the depth of the fastening opening 28, with the diameter of the bridging section 27 also preferably being smaller than the outside diameter of the threaded section 8. The outside diameter of the bridging section 27 is smaller than the diameter of the fastening opening 28 , so that play between the bearing pin 5 and the mounting hole 28 is created. If the stop section 7 is directly connected to the threaded section 8, that is, if there is no bridging section 27, the outer diameter of the threaded section 8 is smaller than the diameter of the fastening opening 28. This also creates play.

Der Aufnahmeabschnitt 6 erstreckt sich in der gezeigten Ausführungsform in eine Lageröffnung 10 am Scharniersupport 9 hinein. Hierdurch wird der Scharniersupport 9 am Lagerbolzen 5 gelagert. Der Scharniersupport 9 umfasst zwei beabstandet zueinander angeordnete Lageröffnungen 10. Die beiden Lageröffnungen 10 liegen in gleichem Abstand zueinander wie die beiden Lagerbolzen 5. Der Anschlagsabschnitt 7 weist in der gezeigten Ausführungsform zum Scharniersupport 9 hin eine Ringfläche 18 auf, auf welcher der Scharniersupport 9 aufsteht.In the embodiment shown, the receiving section 6 extends into a bearing opening 10 on the hinge support 9 . As a result, the hinge support 9 is mounted on the bearing pin 5. The hinge support 9 comprises two bearing openings 10 arranged at a distance from one another. The two bearing openings 10 are at the same distance from one another as the two bearing bolts 5. In the embodiment shown, the stop section 7 has an annular surface 18 towards the hinge support 9, on which the hinge support 9 stands.

Der Aufnahmeabschnitt 6 umfasst weiterhin eine Antriebsstruktur 12, über welche der Lagerbolzen 5 in Drehung um seine Mittelachse M gebracht werden kann. Der Installateur kann mit einem Werkzeug in die Antriebsstruktur 12 eingreifen und somit den Lagerbolzen 5 in Drehung versetzen. Hierdurch wird der Gewindeabschnitt 8 des Lagerbolzens 5 in das Gegengewinde 11 eingeschraubt. Die Lageröffnung 10 ist, wie in den Figuren gezeigt, nach oben hin offen, so dass die Antriebsstruktur 12 von oben her zugänglich und betätigbar ist. Die Zugänglichkeit von oben her kann in den Figuren 2 und 3 besonders gut erkannt werden.The receiving section 6 also includes a drive structure 12, via which the bearing pin 5 can be made to rotate about its central axis M. The installer can reach into the drive structure 12 with a tool and thus set the bearing pin 5 in rotation. As a result, the threaded section 8 of the bearing bolt 5 is screwed into the mating thread 11 . As shown in the figures, the bearing opening 10 is open at the top, so that the drive structure 12 can be accessed and actuated from above. Accessibility from above can be figures 2 and 3 be recognized particularly well.

Bei der Montage kann der Lagerbolzen 5 mit dem Gewindeabschnitt 8 in das Gegengewinde 11 in Eingriff gebracht werden und leicht festgezogen werden, sodass sich das Gegengewinde 11 und der Lagerbolzen 5 relativ zur Auflagefläche 3 innerhalb des Spiels bewegen können. Die Bewegung ist dabei insbesondere quer zur Befestigungsöffnung 28, wobei die Befestigungsöffnung 28 einen Durchmesser aufweist, welcher grösser ist als der maximale Durchmesser des Lagerbolzens 5, so dass ein entsprechendes Spiel bereitstellbar ist. Der Installateur kann nach leichtem Festziehen des Lagerbolzens 5 den Scharniersupport 9 auf dem Aufnahmeabschnitt 6 platzieren und anschliessend das gesamte WC-Klappelement 2 bezüglich der Toilettenschüssel 4 ausrichten. Nach erfolgter Ausrichtung kann der Installateur dann über die Antriebsstruktur 12 dem Lagerbolzen 5 bezüglich des Gegengewindes 11 festziehen, so dass keine weitere Verschiebung mehr erreicht wird. Beim Festziehen wird der Anschlagsabschnitt 7 gegen die Auflagefläche 3 gezogen. Für die Betätigung der Antriebsstruktur 12 kann ein geeignetes Werkzeug in die Lageröffnung 10 eingeführt werden, welches dann in die Antriebsstruktur 12 eingreift, so dass der Lagerbolzen 5 in Drehung bezüglich des feststehenden Gegengewindes gebracht wird.During assembly, the bearing pin 5 can be brought into engagement with the threaded section 8 in the mating thread 11 and tightened slightly so that the mating thread 11 and the bearing pin 5 can move relative to the bearing surface 3 within play. The movement is in particular transverse to the fastening opening 28, the fastening opening 28 having a diameter which is larger than the maximum diameter of the bearing pin 5, so that a corresponding game can be provided. After slightly tightening the bearing bolt 5 , the fitter can place the hinge support 9 on the receiving section 6 and then align the entire toilet folding element 2 with respect to the toilet bowl 4 . After the alignment has taken place, the installer can then tighten the bearing bolt 5 with respect to the mating thread 11 via the drive structure 12 so that no further displacement is achieved. When tightening, the stop section 7 is pulled against the bearing surface 3 . To actuate the drive structure 12, a suitable tool can be inserted into the bearing opening 10, which then engages in the drive structure 12, so that the bearing pin 5 is brought into rotation with respect to the stationary mating thread.

Die Antriebsstruktur 12 erstreckt sich von der Stirnseite 30 des Aufnahmeabschnittes 6 in den Aufnahmeabschnitt 6 hinein. Die Antriebsstruktur 12 ist stirnseitig am freien Ende 13 des Aufnahmeabschnittes 6 angeordnet. Die Antriebstruktur 12 ist integral am Lagerbolzen 5 angeformt und erstreckt sich dabei von dessen Stirnseite in den Aufnahmeabschnitt 6 hinein. Eine Veränderung des Durchmessers des Lagerbolzens 5 im Bereich der Antriebsstruktur 12 ist nicht nötig.The drive structure 12 extends from the end face 30 of the receiving section 6 into the receiving section 6 . The drive structure 12 is arranged on the front side at the free end 13 of the receiving section 6 . The drive structure 12 is formed integrally on the bearing bolt 5 and extends from its end face into the receiving section 6 . A change in the diameter of the bearing pin 5 in the area of the drive structure 12 is not necessary.

Der Aufnahmeabschnitt 6 weist einen konstanten Aussendurchmesser D6 auf, wobei der Aussendurchmesser D6 im Bereich der Antriebstruktur, wie gesagt, keine Vergrösserung aufweist. Der Aussendurchmesser D6 des Aufnahmeabschnittes 6 ist im Wesentlichen identisch zum Durchmesser D10 der Lageröffnung 10. In der gezeigten Ausführungsform weist die Antriebstruktur 12 die Gestalt eines Innensechskantes auf. Die Antriebsstruktur kann aber auch anders ausgebildet sein, wie beispielsweise als Torx.The receiving section 6 has a constant outside diameter D6, with the outside diameter D6 in the region of the drive structure, as stated, not being enlarged. The outer diameter D6 of the receiving section 6 is essentially identical to the diameter D10 of the bearing opening 10. In the embodiment shown, the drive structure 12 has the shape of a hexagon socket. However, the drive structure can also be designed differently, for example as a torx.

In Einbaulage liegt die Antriebsstruktur 12 vollständig im Inneren der Lageröffnung 10. Das heisst, dass auch die Stirnseite 30 vollständig im Inneren der Lageröffnung 10 liegt. Hierdurch ergeht der Vorteil, dass das Ende des Aufnahmeabschnittes 6 im Inneren der Lageröffnung 10 liegt und keine hervorstehenden Teile, welche aus der Lageröffnung 10 nach oben hin hinausragen würden, vorhanden sind.In the installed position, the drive structure 12 is completely inside the bearing opening 10. This means that the end face 30 is also completely inside the bearing opening 10. This has the advantage that the end of the receiving section 6 is located inside the bearing opening 10 and there are no protruding parts that would protrude upwards from the bearing opening 10 .

Von der Figur 2 her kann gut erkannt werden, dass der Anschlagsabschnitt 7 zur Auflagefläche 3 eine Ringfläche 14 aufweist. Zwischen der Ringfläche 14 und der Auflagefläche 3 ist ein elastisches Scheibenelement 15 angeordnet. Das elastische Scheibenelement 15 weist eine Oberseite 16 auf, die komplementär zur Ringfläche 14 ausgebildet ist. Das Scheibenelement 15 ist vorzugsweise aus Kunststoff.Of the figure 2 ago can be seen well that the stop portion 7 to Bearing surface 3 has an annular surface 14 . An elastic disk element 15 is arranged between the annular surface 14 and the bearing surface 3 . The elastic disk element 15 has an upper side 16 which is designed to complement the annular surface 14 . The disc element 15 is preferably made of plastic.

In der gezeigten Ausführungsform ist die Ringfläche 14 des Anschlagsabschnittes 7 als konkav gerundete Fläche ausgebildet, während die Oberseite 16 des Scheibenelementes 15 als konvexe Fläche ausgebildet ist. Hierdurch können Winkeltoleranzen, welche sich durch die Ausbildung der Auflagefläche 3 ergeben können, ausgeglichen werden.In the embodiment shown, the annular surface 14 of the stop section 7 is designed as a concavely rounded surface, while the upper side 16 of the disk element 15 is designed as a convex surface. In this way, angular tolerances that can result from the design of the bearing surface 3 can be compensated.

Die Unterseite 17 des Scheibenelementes 15 liegt auf der Auflagefläche 3 auf. Das Scheibenelement 15 ist dabei vorzugsweise derart dimensioniert, dass der Anschlagsabschnitt 7 nicht direkt auf der Auflagefläche 3 aufliegt. Es handelt sich dabei um eine indirekte Auflage zwischen dem Anschlagsabschnitt 7 und der Auflagefläche 3. Eine direkte Auflage wäre auch denkbar, wobei dann auf das Scheibenelement 15 verzichtet werden kann.The underside 17 of the disk element 15 rests on the support surface 3 . The disk element 15 is preferably dimensioned in such a way that the stop section 7 does not lie directly on the bearing surface 3 . This is an indirect contact between the stop section 7 and the contact surface 3. A direct contact would also be conceivable, in which case the disc element 15 can then be dispensed with.

Der Anschlagsabschnitt 7 weist zum Scharniersupport 9 hin eine weitere Ringfläche auf, auf welcher der Scharniersupport 9 aufsteht. Hier steht der Scharniersupport 9 mit den Randbereichen der Lageröffnung 10 auf der Ringfläche 14 auf.The stop section 7 has a further annular surface towards the hinge support 9, on which the hinge support 9 rests. Here the hinge support 9 rests on the ring surface 14 with the edge areas of the bearing opening 10 .

Das Gegengewinde 11 ist, wie in der Figur 3 gezeigt, ein Bestandteil eines Nutensteins 19. Der Nutenstein 19 ist in einer Nutenbahn 20 in mindestens einer Richtung R1, R2 mit Spiel gelagert. In der gezeigten Ausführungsform kann sich der Nutenstein 19 in zwei verschiedene Richtungen R1, R2, welche rechtwinklig zueinander stehen, frei bewegen. Vorzugsweise ist die Bewegbarkeit derart, dass das Gegengewinde 11 unterhalb der Befestigungsöffnung 28 der Toilettenschüssel 4 jede Position innerhalb der Befestigungsöffnung 28 einnehmen kann.The mating thread 11 is, as in the figure 3 shown, a part of a sliding block 19. The sliding block 19 is mounted in a grooved track 20 in at least one direction R1, R2 with play. In the embodiment shown, the sliding block 19 can move freely in two different directions R1, R2, which are at right angles to one another. The mobility is preferably such that the mating thread 11 below the fastening opening 28 of the toilet bowl 4 can assume any position within the fastening opening 28 .
