Description

Die Erfindung betrifft ein Scharnier für eine aus einem Deckel und einem Sitz gebildete Toilettensitzgarnitur, umfassend einen Rotationsdämpfer zum Abbremsen der Absenkbewegung des Deckels oder des Sitzes um eine Schwenkachse der Toilettensitzgarnitur, ein mit dem Rotationsdämpfer längs der Schwenkachse koaxial gekoppeltes Adapterstück, einen Scharnierbolzen, der in eine in dem Adapterstück ausgebildete Aufnahmebohrung greift, und eine an einer Toilettenschüssel anbringbare Befestigungsbasis, an welcher der Scharnierbolzen gehalten ist. Ferner betrifft die Erfindung eine Toilettensitzgarnitur mit einem Deckel, einem Sitz und einer Befestigungsvorrichtung zur Anbringung an einer Toilettenschüssel, wobei die Befestigungsvorrichtung zwei Scharniere aufweist.The invention relates to a hinge for a toilet seat set formed from a cover and a seat, comprising a rotary damper for braking the lowering movement of the cover or the seat about a pivot axis of the toilet seat set, an adapter piece coupled coaxially with the rotary damper along the pivot axis, a hinge bolt which engages a receiving hole formed in the adapter piece, and a mounting base attachable to a toilet bowl on which the hinge pin is retained. Furthermore, the invention relates to a toilet seat set with a cover, a seat and a fastening device for attachment to a toilet bowl, the fastening device having two hinges.

Ein für eine Toilettensitzgarnitur bestimmtes Scharnier vorstehend genannter Art ist aus der EP 1 199 020 B1 bekannt. Bei diesem Scharnier greift der Scharnierbolzen in eine Aufnahmebohrung eines koaxial mit einem Rotationsdämpfer gekoppelten Adapterstücks. Die Aufnahmebohrung des Adapterstücks ist hierbei als Sackloch ausgebildet, das einen Lochboden aufweist, der den vollständigen Durchtritt des Scharnierbolzens durch das Adapterstück quer zur Schwenkachse verhindert. Da das bei der Montage der Toilettensitzgarnitur in die Aufnahmebohrung des Adapterstücks eingeführte freie Ende des Scharnierbolzens im montierten Zustand an dem Lochboden der Aufnahmebohrung anliegt, wirken vergleichsweise große Auflagerkräfte auf den Scharnierbolzen, wodurch es erforderlich wird, den Scharnierbolzen besonders stabil auszuführen, um Beschädigungen an dem Scharnier zu verhindern.A certain for a toilet seat hinge above type is from EP 1 199 020 B1 known. In this hinge, the hinge pin engages in a receiving bore of an adapter piece that is coupled coaxially to a rotation damper. The mounting hole of the adapter piece is here as a Blind hole formed, which has a hole base that prevents the complete passage of the hinge pin through the adapter piece transversely to the pivot axis. Since the free end of the hinge bolt, which is inserted into the mounting hole of the adapter piece during assembly of the toilet seat set, rests against the bottom of the mounting hole in the mounted state, comparatively large bearing forces act on the hinge bolt, which means that it is necessary to design the hinge bolt to be particularly stable in order to prevent damage to the prevent hinge.

Dokument CN 106 388 682 A offenbart ein Scharnier für eine Toilettensitzgarnitur mit einer Befestigungsbasis und einem Außenrohr, wobei das Außenrohr mit einer Kontaktfläche auf einer Auflagerfläche der Befestigungsbasis aufliegt und das Außenrohr eine Durchgangsbohrung hat.document CN 106 388 682 A discloses a hinge for a toilet seat set with a mounting base and an outer tube, the outer tube resting with a contact surface on a bearing surface of the mounting base and the outer tube having a through hole.

Dokument EP 2 160 967 A2 offenbart ein Toilettenscharnier mit einer Befestigungsbasis und einem Außenrohr, wobei das Außenrohr auf der Basis aufliegt.document EP 2 160 967 A2 discloses a toilet hinge having a mounting base and an outer tube, the outer tube resting on the base.

Aufgabe der vorliegenden Erfindung ist es, ein Scharnier eingangs genannter Art so weiterzubilden, dass es mit einem vergleichsweise einfachen Aufbau besonders stabil ausgeführt ist. Ferner ist es Aufgabe der Erfindung, eine Toilettensitzgarnitur mit einer Befestigungsvorrichtung bereitzustellen, die zur Anbringung der Toilettensitzgarnitur an einer Toilettenschüssel bestimmt ist und besonders kompakt ausgebildete Scharniere aufweist.The object of the present invention is to further develop a hinge of the type mentioned at the outset in such a way that it is designed to be particularly stable with a comparatively simple structure. Furthermore, the object of the invention is to provide a toilet seat set with a fastening device which is intended for attaching the toilet seat set to a toilet bowl and has particularly compact hinges.

Die Erfindung löst diese Aufgaben durch das Scharnier nach Anspruch 1 bzw. die Toilettensitzgarnitur nach Anspruch 9. Vorteilhafte Weiterbildungen sind in den jeweiligen abhängigen Ansprüchen angegeben.The invention solves these problems with the hinge according to claim 1 or the toilet seat set according to claim 9. Advantageous developments are specified in the respective dependent claims.

Das erfindungsgemäße Scharnier für eine aus einem Deckel und einem Sitz gebildete Toilettensitzgarnitur umfasst einen Rotationsdämpfer zum Abbremsen der Absenkbewegung des Deckels oder des Sitzes um eine Schwenkachse der Toilettensitzgarnitur, ein mit dem Rotationsdämpfer längs der Schwenkachse koaxial gekoppeltes Adapterstück, einen Scharnierbolzen, der in eine in dem Adapterstück ausgebildete Aufnahmebohrung greift, und eine an einer Toilettenschüssel anbringbare Befestigungsbasis, an welcher der Scharnierbolzen gehalten ist. Das Scharnier umfasst ferner ein zumindest das Adapterstück umhüllendes Außenrohr mit einer Durchgangsbohrung, durch die der Scharnierbolzen in die Aufnahmebohrung des Adapterstücks greift, wobei auch die Aufnahmebohrung des Adapterstücks als Durchgangsbohrung ausgebildet ist und das Außenrohr eine Kontaktfläche aufweist, die an einer an der Befestigungsbasis ausgebildeten Auflagerfläche aufliegt.The hinge according to the invention for a toilet seat set formed by a lid and a seat comprises a rotary damper for braking the lowering movement of the lid or the seat about a pivot axis of the toilet seat set, coaxial with the rotary damper along the pivot axis coupled adapter piece, a hinge pin that engages in a receiving hole formed in the adapter piece, and a mounting base attachable to a toilet bowl on which the hinge pin is held. The hinge also includes an outer tube that encloses at least the adapter piece and has a through hole, through which the hinge bolt engages in the receiving hole of the adapter piece, the receiving hole of the adapter piece also being designed as a through hole and the outer tube having a contact surface which is on a bearing surface designed on the fastening base rests.

Während bei dem aus dem Stand der Technik bekannten Scharnier die Auflagerkräfte von dem Scharnierbolzen aufgenommen werden, der an dem Lochboden des in dem Adapterstück ausgebildeten Sacklochs anliegt, ist bei dem erfindungsgemäßen Scharnier der in die Aufnahmebohrung des Adapterstücks greifende Scharnierbolzen von Auflagerkräften freigehalten. Denn die Erfindung sieht vor, die Auflagerkräfte durch eine an der Befestigungsbasis ausgebildete Auflagerfläche aufzunehmen, auf der eine Kontaktfläche aufliegt, die an einem das Adapterstück umhüllenden Außenrohr vorgesehen ist. Indem die vorgenannten Flächen an dem Außenrohr bzw. der Befestigungsbasis vorgesehen sind, lassen sie sich ohne großen Fertigungsaufwand so ausführen, dass sie die Auflagerkräfte besonders wirksam aufnehmen. Insbesondere ist im Unterschied zum Stand der Technik keine räumliche Begrenzung auf die in dem Adapterstück vorhandene Aufnahmebohrung bzw. den in die Aufnahmebohrung greifenden Scharnierbolzen gegeben, wodurch das Scharnier erheblich stabiler als bisher ausgeführt werden kann. Zudem vereinfacht der erfindungsgemäße Verzicht eines in dem Adapterstück ausgebildeten Sacklochs zugunsten einer Durchgangsbohrung die Fertigung des Adapterstücks. Außerdem lässt sich das Adapterstück bei Bedarf leichter reinigen, was aus Gründen der Hygiene von Vorteil ist.While in the case of the hinge known from the prior art, the bearing forces are absorbed by the hinge bolt, which is attached to the bottom of the hole in the adapter piece trained blind hole rests, is kept free of bearing forces in the hinge according to the invention of the cross into the receiving bore of the adapter hinge pin. This is because the invention provides for the support forces to be absorbed by a support surface which is formed on the fastening base and on which a contact surface which is provided on an outer tube enveloping the adapter piece rests. Because the aforementioned surfaces are provided on the outer tube or the fastening base, they can be designed without great manufacturing effort in such a way that they absorb the support forces particularly effectively. In particular, in contrast to the prior art, there is no spatial limitation to the mounting hole present in the adapter piece or to the hinge bolt engaging in the mounting hole, as a result of which the hinge can be made considerably more stable than before. In addition, the elimination of a blind hole formed in the adapter piece in favor of a through hole according to the invention simplifies the manufacture of the adapter piece. In addition, the adapter piece can be cleaned more easily if necessary, which is an advantage for reasons of hygiene.

Vorzugsweise weist das Außenrohr einen senkrecht zur Rohrlängsachse (bzw. parallel zur Längsachse des Scharnierbolzens) ausgerichteten Anlagestutzen auf, dessen Stirnfläche die auf der Auflagerfläche der Befestigungsbasis aufliegende Kontaktfläche bildet. Der Anlagestutzen kann beispielsweise als ein seitlich an das Außenrohr ansetzendes, kurzes Rohrstück ausgeführt sein, das die in dem Außenrohr ausgebildete Durchgangsbohrung umgibt. Die der Befestigungsbasis zugewandte Stirnfläche dieses Rohrstücks bildet dann die Kontaktfläche, die mit der Auflagerfläche der Befestigungsbasis in Anlage steht.The outer tube preferably has a contact piece which is aligned perpendicularly to the longitudinal axis of the tube (or parallel to the longitudinal axis of the hinge bolt), the end face of which forms the contact surface resting on the bearing surface of the fastening base. The contact piece can be designed, for example, as a short piece of pipe attached to the side of the outer pipe, which surrounds the through-bore formed in the outer pipe. The end face of this piece of pipe facing the fastening base then forms the contact surface which is in contact with the bearing surface of the fastening base.

Vorzugsweise ist der Anlagestutzen einstückig mit einem Rohrkörper des Außenrohrs ausgebildet. Dies begünstigt einen besonders kompakten Aufbau des erfindungsgemäßen Scharniers.The contact piece is preferably designed in one piece with a tubular body of the outer tube. This favors a particularly compact construction of the hinge according to the invention.

Die Kontaktfläche des Außenrohrs und die Auflagerfläche der Befestigungsbasis sind konisch geformte Flächen. Durch die Konizität der vorgenannten Flächen ist es bei der Montage in besonders einfacher Weise möglich, das Außenrohr lagerichtig auf der Befestigungsbasis auszurichten und dort aufzusetzen.The contact surface of the outer tube and the bearing surface of the mounting base are conically shaped surfaces. Due to the conicity of the aforementioned surfaces During assembly, it is possible in a particularly simple manner to align the outer tube in the correct position on the fastening base and to place it there.

Vorzugsweise ist der Scharnierbolzen in der Aufnahmebohrung des Adapterstücks verrastbar. Hierzu ist in einer besonders bevorzugten Ausführung vorgesehen, dass die Aufnahmebohrung des Adapterstücks eine seitliche Einstecknut hat, in der ein elastisch verformbares flächiges Element sitzt, das seitlich in die Aufnahmebohrung ragt, und dass der Scharnierbolzen an seinem freien Ende einen verjüngten Abschnitt und einen daran anschließenden Rastkopf hat, der gegenüber dem verjüngten Abschnitt aufgeweitet ist. In dieser Ausführungsform wird beim Anbringen der Toilettensitzgarnitur an der Toilettenschüssel das Adapterstück mit seiner Aufnahmebohrung auf den Scharnierbolzen gesteckt, so dass dessen Rastkopf durch das elastisch verformbare flächige Element tritt, bis der verjüngte Abschnitt des Scharnierbolzens in dem flächigen Element gehalten ist. Beim Abziehen der Toilettensitzgarnitur muss dann der elastische Widerstand des flächigen Elementes überwunden werden, um den Rastkopf des Scharnierbolzens aus dem flächigen Element zu lösen.The hinge bolt can preferably be latched in the receiving bore of the adapter piece. For this purpose, a particularly preferred embodiment provides that the mounting hole of the adapter piece has a lateral insertion groove in which an elastically deformable flat element is seated that protrudes laterally into the mounting hole, and that the hinge pin has a tapered section at its free end and an adjoining section Locking head has, which is widened compared to the tapered section. In this embodiment, when attaching the toilet seat set to the toilet bowl, the adapter piece is placed with its receiving bore on the hinge bolt so that its locking head passes through the elastically deformable flat element until the tapered section of the hinge bolt is held in the flat element. When the toilet seat set is pulled off, the elastic resistance of the flat element must then be overcome in order to release the latching head of the hinge bolt from the flat element.

Anstelle der vorgenannten seitlichen Einstecknut kann die Aufnahmebohrung des Adapterstücks auch eine Ringnut haben, in der ein elastisch verformbares Ringelement sitzt, das radial in die Aufnahmebohrung ragt. In diesem Fall erfolgt das Verbinden und Lösen des Rastkopfes mit bzw. von dem Ringelement.Instead of the aforementioned lateral insertion groove, the receiving bore of the adapter piece can also have an annular groove in which an elastically deformable ring element is seated, which protrudes radially into the receiving bore. In this case, the locking head is connected and released with or from the ring element.

Vorzugsweise ist die Befestigungsbasis ein scheibenförmiges Element, das eine Bohrung zur Aufnahme des Scharnierbolzens und ein Langloch zur Aufnahme eines Befestigungselementes hat, das an der Toilettenschüssel anbringbar ist. Das Befestigungselement ist beispielsweise Teil einer Schraubverbindung, wie etwa eine Gewindestange, auf die eine Mutter geschraubt wird, um die Befestigungsbasis an der Toilettenschüssel zu arretieren. Das Langloch ermöglicht dabei eine in Grenzen variable Positionierung der Befestigungsbasis an der Toilettenschüssel.Preferably, the mounting base is a disk-shaped member having a bore for receiving the hinge pin and a slot for receiving a fastener attachable to the toilet bowl. For example, the fastener is part of a threaded connection, such as a threaded rod, onto which a nut is threaded to lock the mounting base to the toilet bowl. The elongated hole allows variable positioning of the mounting base on the toilet bowl within limits.

Das Außenrohr und die Befestigungsbasis sind beispielsweise aus Kunststoff und/oder Metall gefertigt und damit zumindest in ersterem Fall kostengünstig und leicht zu reinigen.The outer tube and the fastening base are made of plastic and/or metal, for example, and are therefore inexpensive and easy to clean, at least in the former case.

Die erfindungsgemäße Toilettensitzgarnitur hat eine Befestigungsvorrichtung, mit der die Toilettensitzgarnitur an einer Toilettenschüssel anbringbar ist, wobei diese Befestigungsvorrichtung zwei Scharniere vorstehend erläuterter Art aufweist.The toilet seat set according to the invention has a fastening device with which the Toilet seat set can be attached to a toilet bowl, this fastening device having two hinges of the type explained above.

Vorzugsweise sind die Außenrohre der beiden Scharniere aus Rohrabschnitten eines einstückigen Außenrohres gebildet. In dieser Ausführung sind die beiden Scharniere vorzugsweise an entgegengesetzten Enden des einstückigen Außenrohres angeordnet. Durch das den beiden Scharnieren gemeinsam zugeordnete Außenrohr ergibt sich ein besonders kompakter Aufbau der Toilettensitzgarnitur.The outer tubes of the two hinges are preferably formed from tube sections of a one-piece outer tube. In this embodiment, the two hinges are preferably located at opposite ends of the one-piece outer tube. The outer tube jointly assigned to the two hinges results in a particularly compact construction of the toilet seat set.

In einer speziellen Ausgestaltung ist der jeweilige Rotationsdämpfer, der mit dem zugehörigen Adapterstück längs der Schwenkachse koaxial gekoppelt ist, außerhalb des einstückigen Außenrohrs angeordnet.In a special embodiment, the respective rotary damper, which is coupled coaxially to the associated adapter piece along the pivot axis, is arranged outside of the one-piece outer tube.

In einer weiteren vorteilhaften Ausführung bremst einer der beiden Rotationsdämpfer die Absenkbewegung des Deckels und der andere Rotationsdämpfer die Absenkbewegung des Sitzes.In a further advantageous embodiment, one of the two rotary dampers brakes the lowering movement of the cover and the other rotary damper brakes the lowering movement of the seat.

Figur 1 zeigt in perspektivischer Ansicht eine Befestigungsvorrichtung 10, die dazu dient, eine aus einem Deckel und einem Sitz gebildete Toilettensitzgarnitur an einer Toilettenschüssel anzubringen. Zur Vereinfachung der Darstellung sind in Figur 1 die Toilettenschüssel und die daran anzubringende Toilettensitzgarnitur weggelassen. figure 1 shows in perspective view a fastening device 10, which serves to attach a toilet seat set formed from a cover and a seat to a toilet bowl. To simplify the presentation, in figure 1 the toilet bowl and the toilet seat set to be attached thereto are omitted.

Die Befestigungsvorrichtung 10 umfasst zwei in Figur 1 allgemein mit 12 und 14 bezeichnete Scharniere, über die sich der Deckel und der Sitz der Toilettensitzgarnitur um eine Schwenkachse S zum Absenken bzw. Anheben schwenken lassen. Die beiden Scharniere 12 und 14 weisen ein gemeinsames, einstückiges Außenrohr 16 sowie jeweils eine scheibenförmige Befestigungsbasis 18 bzw. 20 auf. Das beispielsweise aus Kunststoff gefertigte Außenrohr 16 hat zwei Anlagestutzen 22, 24, die senkrecht zu der mit der Schwenkachse S zusammenfallenden Rohrlängsachse ausgerichtet sind und in später genauer erläuterter Weise auf der zugehörigen Befestigungsbasis 18 bzw. 20 aufsetzen.The fastening device 10 comprises two in figure 1 hinges, generally designated 12 and 14, by means of which the lid and the seat of the toilet seat set can be pivoted about a pivot axis S for lowering and raising respectively. The two hinges 12 and 14 have a common, one-piece outer tube 16 and a disk-shaped mounting base 18 and 20, respectively. The outer tube 16 made of plastic, for example, has two contact sockets 22, 24, which are aligned perpendicular to the longitudinal axis of the tube coinciding with the pivot axis S and are placed on the associated fastening base 18 or 20 in a manner explained in more detail later.

Die beiden Scharniere 12, 14 weisen jeweils ein innerhalb des Außenrohrs 16 angeordnetes Adapterstück auf, das längs der Schwenkachse S koaxial mit einem in Figur 1 nicht gezeigten, außerhalb des Außenrohrs 16 angeordneten Rotationsdämpfer gekoppelt ist. In der perspektivischen Darstellung nach Figur 1 sind die den beiden Scharnieren 12, 14 jeweils zugeordneten Adapterstücke gezeigt und dort mit 26, 27 bezeichnet. Die beiden in dem Außenrohr 16 enthaltenen Adapterstücke wirken mit den ihnen zugeordneten Rotationsdämpfern in an sich bekannter Weise derart zusammen, dass einer der beiden Rotationsdämpfer die Absenkbewegung des Deckels und der andere die Absenkbewegung des Sitzes abbremst.The two hinges 12, 14 each have an adapter piece arranged inside the outer tube 16, which is coaxial along the pivot axis S with an in figure 1 not shown, is coupled outside of the outer tube 16 arranged rotary damper. In the perspective view figure 1 are those of the two hinges 12, 14 respectively assigned adapter pieces and denoted there by 26, 27. The two adapter pieces contained in the outer tube 16 interact with the rotary dampers assigned to them in a manner known per se in such a way that one of the two rotary dampers brakes the lowering movement of the cover and the other brakes the lowering movement of the seat.

Die beiden Scharniere 12, 14 sind im Wesentlichen baugleich ausgeführt. Im Weiteren wird deshalb unter Bezugnahme auf die Figuren 2 bis 12 lediglich der Aufbau des Scharniers 12 im Einzelnen erläutert.The two hinges 12, 14 are essentially identical. In the following, therefore, with reference to the Figures 2 to 12 only the structure of the hinge 12 is explained in detail.

Die das Scharnier 12 bildenden Komponenten sind in ihrer Gesamtheit in den Figuren 3, 6, 7 und 8 dargestellt. Dabei zeigt Figur 3 einen Schnitt durch die in Figur 2 dargestellte Ebene A-A und Figur 7 einen Schnitt durch die in Figur 5 dargestellte Ebene B-B. Die Figuren 6 und 8 zeigen das Scharnier 12 in verschiedenen Seitenansichten. In den Figuren 4 sowie 9 bis 12 sind Teile der das Scharnier 12 bildenden Gesamtanordnung gezeigt.The hinge 12 forming components are in their entirety in the Figures 3 , 6 , 7 and 8th shown. while showing figure 3 a cut through the in figure 2 shown level AA and figure 7 a cut through the in figure 5 shown level BB. the figures 6 and 8th show the hinge 12 in different side views. In the figures 4 and FIGS. 9 through 12, parts of the overall assembly forming hinge 12 are shown.

Das Scharnier 12 weist einen Scharnierbolzen 28 auf, der in einer Bohrung 30 der Befestigungsbasis 18 gehalten ist (vgl. insbesondere Figuren 3 und 7). Der Scharnierbolzen 28 ist aus Metall gefertigt, während die Befestigungsbasis 18 aus Kunststoff besteht. Wie insbesondere in den Figuren 9 und 10 gezeigt, hat die Befestigungsbasis 18 ein Langloch 32, durch das ein in den Figuren nicht gezeigtes Befestigungselement, z.B. eine Gewindestange geführt werden kann, um die Toilettensitzgarnitur an der Toilettenschüssel anzubringen. Die Befestigungsbasis 18 hat ferner ein von ihrer oberen Seite nach oben abstehendes Auflager 34, das eine konisch zulaufende Auflagerfläche 36 und einen daran anschließenden zylinderförmigen Eingriffsabschnitt 38 umfasst (vgl. insbesondere Figuren 9 und 11).The hinge 12 includes a hinge pin 28 which is retained within a bore 30 of the mounting base 18 (see particularly Figs Figures 3 and 7 ). The hinge pin 28 is made of metal while the mounting base 18 is made of plastic. As in particular in the Figures 9 and 10 shown, the mounting base 18 has a slot 32 through which a fastener not shown in the figures, such as a threaded rod can be performed to attach the toilet seat set to the toilet bowl. The mounting base 18 also has a support 34 protruding upwards from its upper side, which comprises a conically tapering support surface 36 and an adjoining cylindrical engagement section 38 (cf. in particular Figures 9 and 11 ).

Der an dem Außenrohr 16 ausgebildete Anlagestutzen 22 hat eine der Befestigungsbasis 18 zugewandte Stirnfläche 40, die in ihrer Form der Auflagerfläche 36 der Befestigungsbasis 18 angepasst, d.h. ebenfalls konisch ausgeführt ist. Die Stirnfläche 40 des Anlagestutzens 22 bildet somit eine Kontaktfläche, mit welcher der Anlagestutzen 22 auf der Auflagerfläche 36 der Befestigungsbasis 18 aufsitzt. Wie insbesondere in Figur 3 gezeigt, hat das Außenrohr 16 innerhalb des Anlagestutzens 22 eine Durchgangsbohrung 42, mit der das Außenrohr 16 auf den Eingriffsabschnitt 38 des Auflagers 34 gesteckt werden kann. Somit greift der Scharnierbolzen 28 durch das Durchgangsloch 42 in das Innere des Außenrohrs 16.The contact piece 22 formed on the outer tube 16 has an end face 40 which faces the fastening base 18 and which is adapted in shape to the bearing surface 36 of the fastening base 18, ie is also designed conically. The end face 40 of the contact piece 22 thus forms a contact surface with which the contact piece 22 is seated on the bearing surface 36 of the fastening base 18 . As in particular in figure 3 shown, the outer tube 16 has a through hole 42 within the contact piece 22, with which the outer tube 16 can be plugged onto the engagement portion 38 of the support 34. The hinge pin 28 thus reaches through the through hole 42 into the interior of the outer tube 16.

Ferner kann das Scharnier 12 ein den Anlagestutzen 22 in der Seitenansicht des Scharniers 12 seitlich umgebendes Verbindungselement 56, wie beispielsweise eine horizontale Feder, aufweisen.Furthermore, the hinge 12 can have a connecting element 56, such as a horizontal spring, which laterally surrounds the contact piece 22 in the side view of the hinge 12.

Wie insbesondere den Figuren 3 und 7 zu entnehmen ist, hat das Adapterstück 26 die Form eines Zylinders und weist eine Aufnahmebohrung 44 für den Scharnierbolzen 28 auf. Die Aufnahmebohrung 44 ist als Durchgangsbohrung ausgeführt und auf die in dem Außenrohr 16 ausgebildete Durchgangsbohrung 42 ausgerichtet. Somit greift der Scharnierbolzen 28 durch die in dem Außenrohr 16 ausgebildete Durchgangsbohrung 42 in die Aufnahmebohrung 44 des Adapterstücks 26.Like the one in particular Figures 3 and 7 can be seen, the adapter piece 26 has the shape of a cylinder and has a receiving bore 44 for the hinge pin 28 . The receiving bore 44 is designed as a through bore and is aligned with the through bore 42 formed in the outer tube 16 . The hinge pin 28 thus engages through the through bore 42 formed in the outer tube 16 into the receiving bore 44 of the adapter piece 26.

Der Scharnierbolzen 28 weist an seinem von der Befestigungsbasis 18 abgewandten freien Ende einen gegenüber seinem Grundkörper verjüngten Abschnitt 46 sowie einen daran anschließenden Rastkopf 48 auf. Der Rastkopf 48 ist gegenüber dem verjüngten Abschnitt 46 aufgeweitet. Innerhalb der Aufnahmebohrung 44 des Adapterstücks 26 ist eine seitliche Einstecknut 50 ausgebildet, in der ein elastisch verformbares flächiges Element 52 aufgenommen ist (vgl. insbesondere Figuren 3 und 12). Das flächige Element 52 hat eine mittige Ringöffnung 54, die derart an den verjüngten Abschnitt 46 und den Rastkopf 48 des Scharnierbolzens 28 angepasst ist, dass der Scharnierbolzen 28 beim Aufsetzen des Außenrohrs 16 auf die Befestigungsbasis 18 zunächst mit seinem Rastkopf 48 unter Aufweitung der Ringöffnung 54 durch das flächige Element 52 tritt und anschließend an seinem verjüngten Abschnitt 26 infolge der Elastizität des flächigen Elements 52 in dessen Ringöffnung 54 gehalten und damit verrastet ist. Zum Abziehen des Außenrohrs 16 von der Befestigungsbasis 18 muss somit der elastische Widerstand überwunden werden, mit dem der verjüngte Abschnitt 46 des Scharnierbolzens 28 in der Ringöffnung 54 des flächigen Elementes 52 gehalten ist.At its free end facing away from the fastening base 18 , the hinge pin 28 has a section 46 that is tapered in relation to its base body and a latching head 48 adjoining it. The latching head 48 is widened compared to the tapered section 46 . A lateral insertion groove 50 is formed within the receiving bore 44 of the adapter piece 26, in which an elastically deformable flat element 52 is received (cf. in particular Figures 3 and 12 ). The flat element 52 has a central annular opening 54, which is adapted to the tapered section 46 and the latching head 48 of the hinge bolt 28 in such a way that when the outer tube 16 is placed on the fastening base 18, the hinge bolt 28 first snaps with its latching head 48, thereby widening the annular opening 54 passes through the flat element 52 and is then held at its tapered section 26 due to the elasticity of the flat element 52 in its annular opening 54 and locked therewith. In order to pull the outer tube 16 off the fastening base 18, the elastic resistance with which the tapered section 46 of the hinge pin 28 is held in the ring opening 54 of the flat element 52 must be overcome.

Wie insbesondere die Darstellung gemäß Figur 3 veranschaulicht, wirken bei dem erfindungsgemäßen Scharnier 12 keinerlei Auflagerkräfte auf den Scharnierbolzen 28. Vielmehr werden sämtliche Auflagerkräfte von der an der Befestigungsbasis 18 ausgebildeten Auflagerfläche 36 aufgenommen, auf der die Kontaktfläche 40 des Anlagestutzens 22 aufsetzt. Somit ist das Scharnier 12 bei einem vergleichsweise einfachen Aufbau besonders kompakt ausgebildet.As in particular the representation according to figure 3 illustrated, no bearing forces act on the hinge pin 28 in the hinge 12 according to the invention. Rather, all bearing forces are absorbed by the bearing surface 36 formed on the fastening base 18, on which the contact surface 40 of the contact piece 22 touches down. The hinge 12 is thus of particularly compact design with a comparatively simple structure.
