A compression spring (21) counteracting the stroke movement is arranged in the upper hub, where the spring is supported in an upper front side of the bolt.

Description

Die Erfindung betrifft ein Türband für einen einer Türöffnung zugeordneten, selbstschließenden Türflügel mit einem am Türflügel angebrachten und einem im Bereich des Rands der Türöffnung angebrachten Scharnierteil, wobei die beiden Scharnierteile mittels eines Scharnierbolzens gegeneinander verdrehbar und in axialer Richtung gegeneinander verschiebbar miteinander verbunden sind, wobei der Scharnierbolzen mit einem der beiden Scharnierteile fest verbunden ist und wenigstens eine zumindest einen Abschnitt eines Schraubengangs umfassende Kulissennut aufweist, in die ein auf dem jeweils anderen Scharnierteil aufgenommenes Führungselement eingreift.The invention relates to a door hinge for a door opening associated, self-closing door with a door attached to the door and mounted in the region of the edge of the door hinge part, wherein the two hinge parts by means of a hinge pin against each other rotatable and mutually slidably connected to each other in the axial direction, wherein the Hinge bolt is firmly connected to one of the two hinge parts and at least one at least a portion of a screw groove comprehensive Kulissennut, into which engages a recorded on the other hinge part guide element.

Bei einer Anordnung dieser Art wird der Türflügel während einer Öffnungs-Schwenkbewegung entgegen der Schwerkraft angehoben, die anschließend eine Absenkung unter gleichzeitiger Durchführung einer Schließbewegung bewirkt.In an arrangement of this type, the door leaf is raised against gravity during an opening pivoting movement, which subsequently causes a lowering while simultaneously performing a closing movement.

Aus der US 2002/0062533 A1 ist eine Anordnung eingangs erwähnter Art bekannt. Diese beschreibt einen automatischen Türschließer, welcher die Schwerkraft zur Schließung der Tür nutzt. Das Scharnier weist ein erstes und ein zweites Scharnierteil auf, die mittels eines Gelenkbolzens gegeneinander verdrehbar sind, wobei der Gelenkbolzen mit dem zweiten Scharnierteil über ein mittiges Scharnierteil fest verbunden ist. Der Gelenkbolzen greift mit seinen Enden drehbar und axial verschiebbar in zugeordnete Naben des ersten Scharnierteils ein. Der Gelenkbolzen weist eine schraubenförmige Fläche am unteren Ende auf, die in Eingriff mit einer schraubenförmigen Fläche der unteren Nabe bringbar ist. In der oberen Nabe ist eine einer Hubbewegung des Gelenkbolzens entgegenwirkende Spiralfeder angeordnet, die am Gelenkbolzen abgestützt ist. Die Spiralfeder ist über einen Kugelring an der oberen Stirnseite des Gelenkbolzens abgestützt. Der Kugelring liegt direkt an der oberen Stirnseite des Gelenkbolzens an mehreren Stellen punktförmig an. Die Spiralfeder umfasst die axiale, vom Gelenkbolzen nach oben abstehende Stange und ist auf einer Unterlegscheibe abgestützt, die wiederum auf dem Kugelring aufliegt. Der Kugelring nimmt mittig die axiale Stange komplett auf und liegt im äußeren Bereich jeweils über mehrere Punktauflagen an der Stirnseite des Gelenkbolzens an. Es ergibt sich daher eine ringförmige Anlagefläche mit vergleichsweise großem Durchmesser und großer Gesamtfläche.From the US 2002/0062533 A1 An arrangement of the kind mentioned is known. This describes an automatic door closer, which uses gravity to close the door. The hinge has a first and a second hinge part, which are mutually rotatable by means of a hinge pin, wherein the hinge pin is fixedly connected to the second hinge part via a central hinge part. The hinge pin engages with its ends rotatable and axially displaceable in associated hubs of the first hinge part. The hinge pin has a helical surface at the lower end, which is engageable with a helical surface of the lower hub. In the upper hub is a helical spring counteracting a lifting movement of the hinge pin arranged, which is supported on the hinge pin. The coil spring is supported by a ball ring on the upper end side of the hinge pin. The ball ring is punctiform at several points directly on the upper end face of the hinge pin. The coil spring comprises the axial, upwardly projecting rod from the hinge pin and is supported on a washer, which in turn rests on the ball ring. The ball ring takes in the middle of the axial rod completely and is in the outer region in each case on several point supports on the front side of the hinge pin. It therefore results in an annular contact surface with a comparatively large diameter and large total area.

Ein gattungsgemäßes Türband ist ebenso aus CH259775 bekannt.A generic door hinge is also off CH259775 known.

Hiervon ausgehend ist es die Aufgabe der vorliegende Erfindung, das Türband so zu verbessern, dass eine hohe Zuverlässigkeit und Störungsfreiheit erreicht wird und dennoch eine ästhetisch ansprechende Ausführung möglich ist.On this basis, it is the object of the present invention to improve the door hinge so that a high reliability and freedom from interference is achieved and yet an aesthetically pleasing design is possible.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1.

Das Türband ist mit einem an einem Türflügel angebrachten und einem im Bereich des Rands der Türöffnung angebrachten Scharnierteil versehen, wobei die beiden Scharnierteile mittels eines Scharnierbolzens gegeneinander verdrehbar und in axialer Richtung gegeneinander verschiebbar miteinander verbunden sind. Der Scharnierbolzen (6) ist mit einem der beiden Scharnierteile fest verbunden und weist wenigstens eine zumindest einen Abschnitt eines Gewindegangs umfassende, radiale Kulissennut auf, in die ein auf dem jeweils anderen Scharnierteil aufgenommenes, von einer in das Scharnierteil radial einschraubbaren Schraube abstehendes Führungselement eingreift. Der Scharnierbolzen ist am flügelseitigen Scharnierteil befestigt und greift mit seinen Enden drehbar und axial verschiebbar in zugeordnete Naben des öffnungrandseitigen Scharnierteils ein. Das in die Kulissennut eingreifende Führungselement ist in der unteren Nabe aufgenommen, wobei in der oberen Nabe eine einer Hubbewegung des Scharnierbolzens entgegenwirkende Druckfeder angeordnet ist, die über ein nach unten sich verjüngendes Stützelement zumindest achsnah an der oberen Stirnseite des Scharnierbolzens abgestützt ist. Das Stützelement ist als Kugel ausgebildet und liegt punktförmig an der oberen Stirnseite des Scharnierbolzens an.The door hinge is provided with a mounted on a door leaf and a mounted in the region of the edge of the door opening hinge part, wherein the two hinge parts by means of a hinge pin against each other rotatable and mutually slidably connected to each other in the axial direction. The hinge pin (6) is fixedly connected to one of the two hinge parts and has at least one at least a portion of a thread, radial gate groove into which engages a received on the other hinge part, protruding from a radially screwed into the hinge screw screw guide element. The hinge pin is attached to the wing-side hinge part and engages with its ends rotatable and axially displaceable in associated hubs of the opening edge-side hinge part. The engaging in the cam groove guide member is received in the lower hub, wherein in the upper hub of a lifting movement of the hinge pin counteracting compression spring is arranged, which tapers over a downward Supporting element is supported at least axially close to the upper end side of the hinge pin. The support element is designed as a ball and is punctiform on the upper end side of the hinge pin.

Diese Maßnahmen ergeben eine Ausführung, bei der der Scharnierbolzen mit dem Türflügel während einer Schwenkbewegung angehoben und abgesenkt wird. Es ist daher möglich, die die Senkbewegung und damit die Schließbewegung unterstützende Druckfeder der Stirnseite des oberen, in die obere Nabe des öffnungsrandseitigen Scharnierteils eingreifenden Endes des Scharnierbolzens zuzuordnen. Die Druckfeder kann daher in vorteilhafter Weise in der oberen Nabe angeordnet sein und tritt daher offen nicht in Erscheinung, was sich vorteilhaft auf die Gestaltungsschönheit und die Vermeidung von Unfällen auswirkt. Gleichzeitig ergibt sich in vorteilhafter Weise eine axiale Hintereinanderanordnung von Scharnierbolzen und Druckfeder, so dass deren Kraft in die obere Stirnseite des heb- und senkbaren Scharnierbolzens eingeleitet wird. Dadurch, dass die Druckfeder über ein nach unten sich verjüngendes Stützelement zumindest achsnah an der oberen Stirnseite des Scharnierbolzens abgestützt ist, werden der Schließ-Schwenkbewegung entgegenwirkende Reibmomente weitestgehend ausgeschlossen, was der Lösung der Aufgabe hinsichtlich Störungsfreiheit und Zuverlässigkeit sehr förderlich ist. Außerdem wird durch die Ausbildung des Stützelements als Kugel in vorteilhafter Weise eine punktförmige, koaxiale Anlage an der oberen Stirnseite des Scharnierbolzens ermöglicht. Die Kugel eignet sich gleichzeitig für eine Aufnahme des ringförmigen, unteren Endes der Druckfeder. Die erfindungsgemäßen Maßnahmen ergeben daher eine hohe Zuverlässigkeit und Funktionssicherheit sowie eine schlanke Bauweise und damit eine gute Ästhetik.These measures result in an embodiment in which the hinge pin is raised and lowered with the door during a pivoting movement. It is therefore possible to associate the compression spring supporting the lowering movement and thus the closing movement of the end face of the upper, engaging in the upper hub of the opening edge side hinge part end of the hinge pin. The compression spring can therefore be arranged in an advantageous manner in the upper hub and therefore does not appear open, which has an advantageous effect on the design beauty and the prevention of accidents. At the same time results in an advantageous manner, an axial succession of hinge pin and compression spring, so that their force is introduced into the upper end face of the raised and lowered hinge pin. The fact that the compression spring is supported by a downwardly tapered support element at least close to the axis of the upper end of the hinge pin, the closing pivotal movement counteracting friction moments are largely excluded, which is very conducive to solving the problem in terms of fault-free and reliable. In addition, a punctiform, coaxial contact with the upper end face of the hinge pin is made possible by the formation of the support element as a ball in an advantageous manner. The ball is also suitable for receiving the annular, lower end of the compression spring. The measures according to the invention therefore provide high reliability and reliability as well as a slim design and thus a good aesthetics.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous embodiments and expedient developments of the higher-level measures are specified in the subclaims.

Eine besonders vorteilhafte Maßnahme zur Förderung von Zuverlässigkeit und Störungsfreiheit kann darin bestehen, dass zumindest die in die Naben eingreifenden Bereiche, des Scharnierbolzens mit einer umfangsseitigen Gleitbeschichtung versehen sind. Dies erhöht die Leichtgängigkeit. Die Gleitbeschichtung kann vorteilhaft als Diamantstaubbeschichtung ausgebildet sein. Die Gleitbeschichtung kann ein Stützelement oben genannter Art entbehrlich machen und umgekehrt. Selbstverständlich können die beiden Maßnahmen aber auch sich gegenseitig unterstützend gleichzeitig zur Anwendung kommen.A particularly advantageous measure to promote reliability and freedom from interference may be that at least the areas engaging in the hubs, the hinge pin are provided with a circumferential sliding coating. This increases the ease of movement. The lubricious coating may advantageously be formed as a diamond dust coating. The sliding coating can make a support element of the above type dispensable and vice versa. Of course, the two measures can also be used mutually supportive at the same time.

In weiterer Fortbildung der übergeordneten Maßnahmen kann die Kulissennut einen rechteckförmigen Querschnitt aufweisen, so dass das Gleitelement als Gleitstein ausgebildet sein kann. Dies ergibt eine sehr robuste Ausführung, die eine hohe Funktionssicherheit und Störungsfreiheit gewährleistet. Der Gleitstein kann dabei einfach als vorderer Zylinderzapfen einer in die vordere Nabe einschraubbaren Schraube ausgebildet sein.In a further development of the higher-level measures, the guide groove may have a rectangular cross section, so that the sliding element may be designed as a sliding block. This results in a very robust design that ensures high reliability and freedom from interference. The sliding block can simply be designed as a front cylinder journal of a screw which can be screwed into the front hub.

Eine weitere vorteilhafte Ausgestaltung kann darin bestehen, dass die Kulissennut als in sich geschlossene Schrägnut mit um 180° gegeneinander versetzten Scheitelpunkten ausgebildet ist. Die endlose Gestaltung der Kulissennut erleichtert die Herstellung. Gleichzeitig ermöglicht diese Ausführung auch einen Einsatz bei Pendeltüren. Außerdem kann hierbei derselbe Scharnierbolzen sowohl für rechts öffnende als auch für links öffnende Türflügel Verwendung finden.A further advantageous embodiment may consist in that the slide groove is formed as a self-contained oblique groove with 180 ° offset from one another vertices. The endless design of the gate groove facilitates the production. At the same time, this version also allows use with swing doors. In addition, the same hinge pin can be used for both right-opening and left-opening door wings.

Die der Figur 1 zugrundeliegende Türanordnung enthält einen zum Verschließen einer zugeordneten Türöffnung 1 vorgesehenen Türflügel 2, der durch mehrere, in der Regel zwei in der Höhe gegeneinander versetzte Türbänder 3 schwenkbar an einem Rand der Türöffnung 1 gelagert ist. Die Türbänder 3 enthalten jeweils ein im Bereich des zugeordneten, vertikalen Rands der Türöffnung 1 angebrachtes Scharnierteil 4 und ein am gegenüberliegenden Rand des Türflügels 2 angebrachtes Scharnierteil 5.The the FIG. 1 underlying door assembly includes a provided for closing an associated door opening 1 door leaf 2, which is supported by a plurality of, usually two offset in height staggered door hinges 3 pivotally mounted on an edge of the door opening 1. The hinges 3 each contain a hinged part 4 mounted in the region of the associated vertical edge of the door opening 1 and a hinge part 5 attached to the opposite edge of the door leaf 2.

Die beiden Scharnierteile 4, 5 sind mittels eines Scharnierbolzens 6 miteinander verbunden. Der Scharnierbolzen 6 ist dabei mit dem flügelseitigen Scharnierteil 5 fest verbunden und mit dem öffnungsrandseitigen Scharnierteil 4 beweglich im Eingriff, wobei eine Schwenkbewegung und Axialbewegung möglich ist. Das flügelseitige Scharnierteil 5 besitzt einen am Flügel 2 festlegbaren Tragarm 7, an dem eine am besten aus Figur 2 entnehmbare Büchse 8 befestigt ist, die auf den Scharnierbolzen 6 aufgesteckt und fest hiermit verbunden ist. Im dargestellten Beispiel ist die Büchse 8 mittels eines durchgehenden Stifts 9 mit dem Scharnierbolzen 6 verstiftet.The two hinge parts 4, 5 are connected to each other by means of a hinge pin 6. The hinge pin 6 is fixedly connected to the wing-side hinge part 5 and movable with the opening edge side hinge part 4 in engagement, wherein a pivoting movement and axial movement is possible. The wing-side hinge part 5 has a wing 2 fixable support arm 7, on which one of the best FIG. 2 removable sleeve 8 is fixed, which is attached to the hinge pin 6 and firmly connected thereto. In the example shown, the sleeve 8 is pinned by means of a continuous pin 9 with the hinge pin 6.

Das öffnungsrandseitige Scharnierteil 4 enthält, wie Figur 2 weiter erkennen lässt, ein am zugeordneten Öffnungsrand festlegbares, hier winkelförmiges Tragstück 10, das zwei in axialer Richtung voneinander distanzierte, fluchtend übereinander angeordnete Naben 11, 12 enthält, in die der Scharnierbolzen 6 mit seinen Endbereichen drehbar und in axialer Richtung verschiebbar eingreift. Die winkelförmige Ausbildung des Tragstücks 10 ermöglicht in vorteilhafter Weise dessen Eingriff in den Falz eines Türstocks sowie eine eine Ecke des Türstocks umgreifende Anordnung, wie Figur 1 anschaulich zeigt. Das Tragstück 10 kann aufgesetzt oder versenkt angeordnet sein.The opening edge-side hinge part 4 contains, as FIG. 2 can be seen, a fixable at the associated opening edge, here angular support member 10, the two axially spaced from each other, aligned superposed hubs 11, 12, into which the hinge pin 6 rotatably engages with its end portions and displaceable in the axial direction. The angular formation of the support piece 10 advantageously allows its engagement in the fold of a door frame and a corner of the door frame embracing arrangement, such as FIG. 1 clearly shows. The support piece 10 may be placed or sunk.

Die Naben 11, 12 können unlösbar mit dem Tragstück 10 verbunden sein. lm dargestellten Beispiel sind die Naben 11, 12, wie am besten aus Figur 3 erkennbar ist, mittels Schrauben 13 lösbar am Tragstück 10 festlegbar. Die Naben 11, 12 kommen mit einer Anlagefläche 14 an der zugewandten Gegenfläche eines Schenkels des Tragstücks 10 zur Anlage, der mit den Schrauben 13 zugeordneten Durchgangslöchern versehen ist, denen nabenseitig vorgesehene Gewindebohrungen 15 zugeordnet sind. Die Schrauben 13 sind zweckmäßig mit einem Senkkopf versehen. Dementsprechend sind die zugeordneten Durchgangslöcher als Senklöcher ausgebildet. Der mehrteilige Aufbau der Scharnierteile und insbesondere des Scharnierteils 4 mit lösbar und damit auswechselbar am Tragstück 10 anbringbaren Naben 11,12 ergibt eine hohe Vielseitigkeit mit vielen Kombinationsmöglichkeiten.The hubs 11, 12 may be permanently connected to the support piece 10. In the illustrated example, the hubs 11, 12 are as best as possible FIG. 3 can be seen, releasably secured by screws 13 on the support piece 10. The hubs 11, 12 come with a contact surface 14 on the opposite mating surface of a leg of the support member 10 to the plant, which is provided with the screws 13 associated through holes, which are assigned to the hub side provided threaded holes 15. The screws 13 are expediently provided with a countersunk head. Accordingly, the associated through holes are formed as sink holes. The multi-part construction of the hinge parts and in particular of the hinge part 4 with releasably and thus replaceably attachable to the support piece 10 hub 11,12 results in a high versatility with many possible combinations.

Der in die Naben 11, 12 eingreifende Scharnierbolzen 6 ist zur Erzielung einer leichtgängigen Lagerung zumindest im Bereich seiner in die Naben 11, 12 eingreifenden Enden mit einer Gleitbeschichtung versehen. Zur Bildung der Gleitbeschichtung kann vorzugsweise Diamantpulver Verwendung finden. Der beweglich in die Naben 11, 12 eingreifende Scharnierbolzen 6 durchgreift die fest hiermit verbundene Büchse 8 des flügelseitigen Scharnierteils 5, die sich im Montagezustand, wie aus Figur 2 ersichtlich ist, im Bereich zwischen den Naben 11, 12 befindet. Die Länge der Büchse 8 ist kleiner als der axiale Abstand der Naben 11, 12, so dass eine Hubbewegung der Büchse 8 möglich ist.The engaging in the hubs 11, 12 hinge pin 6 is provided to achieve a smooth bearing at least in the region of its engaging in the hubs 11, 12 ends with a sliding coating. Diamond powder may preferably be used to form the lubricious coating. The movable in the hubs 11, 12 engaging hinge pin 6 passes through the fixed hereby associated sleeve 8 of the wing-side hinge part 5, which in the assembled state, as from FIG. 2 it can be seen, located in the area between the hubs 11, 12. The length of the sleeve 8 is smaller than the axial distance of the hubs 11, 12, so that a lifting movement of the sleeve 8 is possible.

Wenigstens eines der übereinander angeordneten Türbänder, vorzugsweise alle übereinander angeordneten Türbänder, ist bzw. sind mit einem Selbstschließ-Mechanismus versehen, wobei der Türflügel 2 samt der hieran befestigten Teile im Verlauf der Öffnungs-Schwenkbewegung entgegen der Schwerkraft angehoben wird und wobei, sobald der geöffnete Türflügel 2 losgelassen wird, dessen Gewicht eine Bewegungsumkehr mit Senk- und gleichzeitiger Schließbewegung bewirkt.At least one of the stacked door hinges, preferably all stacked door hinges, is or are provided with a self-closing mechanism, wherein the door leaf 2 together with the parts attached thereto in the course of the opening pivoting movement is raised against gravity and wherein, as the open Door 2 is released, the weight causes a reversal of motion with lowering and simultaneous closing movement.

Hierzu ist der Scharnierbolzen 6, wie die Figuren 2 und 3 weiter erkennen lassen, in seinem in die untere Nabe eingreifenden Endbereich mit wenigstens einer zumindest einen Abschnitt eines Gewindegangs umfassenden Kulissennut 16 versehen, in die ein auf der unteren Nabe 11 des randseitigen Scharnierteils 4 aufgenommenes Führungselement 17 eingreift. Die Kulissennut 16 besitzt, wie am besten aus Figur 3 erkennbar ist, einen rechteckförmigen Querschnitt. Das in die Kulissennut 16 eingreifende Führungselement 17 kann dabei als stationär angeordneter Gleitstein ausgebildet sein. Im dargestellten Beispiel ist hierzu, wie am besten aus Figur 3 erkennbar ist, ein Zylinderzapfen vorgesehen, der von einer in eine zugeordnete Gewindebohrung 18 der Nabe 11 einschraubbaren, zweckmäßig als Madenschraube ausgebildeten Schraube 19 absteht. Das mit der Kulissennut 16 zusammenwirkende Führungselement bewirkt eine Umsetzung einer Schwenkbewegung in eine Axialbewegung und umgekehrt, was in der gewünschten Weise zum Heben des Türflügels 2 beim Öffnen und zum Schließen des Türflügels 2 beim Absenken führt.For this purpose, the hinge pin 6, as the Figures 2 and 3 can be seen further provided in its engaging in the lower hub end portion with at least one at least a portion of a thread comprehensive Kulissennut 16, into which engages a received on the lower hub 11 of the peripheral hinge part 4 guide member 17. The Kulissennut 16 has, as best of FIG. 3 can be seen, a rectangular cross-section. The engaging in the cam groove 16 guide member 17 may be formed as a stationary arranged sliding block. In the example shown, this is how best off FIG. 3 can be seen, a cylinder pin provided, which protrudes from a screwed into an associated threaded bore 18 of the hub 11, suitably designed as a grub screw screw 19. The co-operating with the guide groove 16 guide member causes a conversion of a pivoting movement in an axial movement and vice versa, which leads in the desired manner for lifting the door leaf 2 when opening and closing the door leaf 2 when lowering.

Die Kulissennut 16 ist, wie Figur 3 weiter erkennen lässt, als umlaufende Schrägnut mit um 180° gegeneinander versetzten Scheiteln ausgebildet. Die Steigung, das heißt der Axialabstand der Scheitel entspricht höchstens der in Figur 2 angedeuteten Differenz d zwischen dem lichten Axialabstand der beiden Naben 11,12 und der Länge der dazwischen angeordneten Büchse 8. Die genannte Steigung beträgt im dargestellten Beispiel vorteilhaft 10mm. Der Neigungswinkel, d.h. die Schräge der die Kulissennut bildenden Schrägnut beträgt bevorzugt 45°, was sowohl beim Heben als auch beim Senken des Türflügels gute Gleitverhältnisse ergibt.The Kulissennut 16 is how FIG. 3 can be seen, as a circumferential oblique groove formed with 180 ° staggered vertices. The slope, that is the axial distance of the vertex corresponds at most to in FIG. 2 indicated difference d between the clear axial distance of the two hubs 11,12 and the length of the sleeve 8 arranged therebetween. The said slope is in the illustrated example advantageously 10mm. The inclination angle, ie the slope of the groove groove forming the inclined groove is preferably 45 °, which gives both when lifting and when lowering the door good sliding conditions.

Der Scharnierbolzen 6 ist in der Montagestellung so eingestellt, dass das in die Kulissennut 16 eingreifende Führungselement 17 in der Schließstellung des Türflügels 2 sich etwas unterhalb des oberen Scheitelpunkts der Kulissennut 16 befindet, so dass eine den Türflügel 2 in einer zuverlässigen Anlage an einer zugeordneten, öffnungsrandseitigen Anlagefläche haltende Kraft erzeugt wird. Auf diese Weise wird beim Öffnen des Türflügels der untere Scheitelpunkt überfahren, was in vorteilhafter Weise dazu führt, dass der Türflügel im letzten Winkelbereich der Öffnungsbewegung automatisch offen gehalten wird. Zweckmäßig steht das Führungselement 17 in der Schließstellung 15-20 Schwenkwinkelgrade vor dem oberen Scheitelpunkt.The hinge pin 6 is set in the mounting position so that the engaging in the cam groove 16 guide member 17 in the closed position of the door leaf 2 is slightly below the upper apex of the cam groove 16 so that the door 2 in a reliable investment in an associated, Opening edge side bearing surface holding force is generated. In this way, when the door leaf is opened, the lower vertex is run over, which advantageously leads to the fact that the door is automatically kept open in the last angular range of the opening movement. Suitably, the guide element 17 is in the closed position 15-20 pivot angle degrees in front of the upper vertex.

Das dem Stift 9, der den Scharnierbolzen 6 mit der Büchse 8 verbindet, zugeordnete Loch kann vorgebohrt sein. Vorteilhaft können im Scharnierbolzen 6 auch mehrere vorgebohrte Löcher vorgesehen sein, so dass unterschiedliche Drehstellungen des Scharnierbolzens 6 in der Ausgangslage gewählt werden können. Es wäre aber auch denkbar, das dem Stift 9 zugeordnete Loch vor Ort zu bohren, so dass jede gewünschte Einstellung erreicht werden kann.The pin 9, which connects the hinge pin 6 with the sleeve 8, associated hole may be predrilled. Advantageously, a plurality of predrilled holes may be provided in the hinge pin 6, so that different rotational positions of the hinge pin 6 can be selected in the starting position. But it would also be possible to drill the hole assigned to the pin 9 on site, so that any desired setting can be achieved.

Zweckmäßig kann der Scharnierbolzen 6 mit einer von außen sichtbaren Winkelmarkierung versehen sein. Hierzu kann der Scharnierbolzen 6 mit einer im Bereich seiner unteren Stirnseite vorgesehenen, in Figur 3 angedeuteten Kerbe 20 versehen sein, die über eine zugeordnete Öffnung der unteren Nabe 11 einsehbar ist. Im dargestellten Beispiel ist die untere Nabe 11 einfach nach unten offen, so dass die Kerbe 20 von unten zugänglich ist. Es wäre auch denkbar, die Kerbe 20 so auszubilden, dass ein Werkzeug angesetzt werden kann, mittels dessen der Scharnierbolzen 6 zwecks vor seiner Verbindung mit der Buchse 8 entsprechender Einstellung verdreht werden kann.Suitably, the hinge pin 6 may be provided with an externally visible angle marking. For this purpose, the hinge pin 6 provided with a in the region of its lower end face, in FIG. 3 indicated notch 20 may be provided, which is visible through an associated opening of the lower hub 11. In the example shown, the lower hub 11 is simply open at the bottom, so that the notch 20 is accessible from below. It would also be conceivable to design the notch 20 in such a way that a tool can be attached by means of which the hinge pin 6 can be rotated for the purpose of setting it before its connection to the bush 8.

In der oberen Nabe 12 des öffnungsrandseitigen Scharnierteils 4 ist, wie die Figuren 2 und 4 erkennen lassen, eine einer Hubbewegung des Türflügels 2 und damit des hiermit verbundenen Scharnierbolzens 6 entgegenwirkende Druckfeder 21 angeordnet, die mit ihrem oberen Ende an einer hier die obere Nabe nach oben verschließenden, nabenseitigen Querwand 22 und mit ihrem unteren Ende auf der oberen Stirnseite des mit seinem oberen Endbereich in die obere Nabe 11 eingreifenden Scharnierbolzens 6 abgestützt ist. Zwischen dem unteren Ende der Druckfeder 21 und der oberen Stirnseite des Scharnierbolzens 6 ist ein Stützelement 23 angeordnet, das die Federkraft auf den Scharnierbolzen 6 überträgt.In the upper hub 12 of the opening edge-side hinge part 4 is like the Figures 2 and 4 let recognize a one of a lifting movement of the door leaf 2 and thus the associated hinge pin 6 counteracting compression spring 21 arranged with its upper end to a here the upper hub upwardly closing, hub side transverse wall 22 and with its lower end on the upper face of the its upper end portion in the upper hub 11 engaging hinge pin 6 is supported. Between the lower end of the compression spring 21 and the upper end face of the hinge pin 6, a support member 23 is arranged, which transmits the spring force to the hinge pin 6.

Das Stützelement 23 ist so ausgebildet, dass eine möglichst zentrale Krafteinleitung in den Scharnierbolzen 6 erreicht wird. Hierzu besitzt das Stützelement 23 eine nach unten konvergierende Kontur. Im dargestellten Beispiel ist das Stützelement 23 als Kugel ausgebildet, die praktisch punktförmig im Bereich der Achse des Scharnierbolzens 6 an diesem anliegt. Gleichzeitig ergibt sich im Bereich der oberen Hälfte der Kugel eine nach oben konvergierende Kontur, mit welcher die Kugel in das ringförmige, untere Ende der Druckfeder 21 eingreifen kann, so dass sich eine saubere Anlage auf dem ganzen Umfang sowie eine zuverlässige Zentrierung der Kugel ergeben.The support element 23 is designed so that as central as possible force introduction into the hinge pin 6 is achieved. For this purpose, the support element 23 has a downwardly converging contour. In the illustrated example, the support member 23 is formed as a ball which rests practically punctiform in the region of the axis of the hinge pin 6 at this. At the same time results in the upper half of the ball an upwardly converging contour with which the ball can engage in the annular, lower end of the compression spring 21, so that there is a clean investment on the entire circumference and a reliable centering of the ball.

Der Außendurchmesser der Druckfeder 21 entspricht im zusammengedrückten Zustand dem lichten Durchmesser der Bohrung der oberen Nabe 11, was eine zuverlässige Zentrierung ergibt. Dasselbe kann für den Durchmesser der das Stützelement 23 bildenden Kugel gelten. Im dargestellten Beispiel ist der Durchmesser der Kugel etwas kleiner, so dass diese Bewegungsspiel hat.The outer diameter of the compression spring 21 corresponds in the compressed state, the clear diameter of the bore of the upper hub 11, which results in a reliable centering. The same may apply to the diameter of the ball 23 forming the support element. In the example shown, the diameter of the ball is slightly smaller, so that this has motion play.

Die Vorspannung der Druckfeder 21 im geschlossenen Zustand kann zweckmäßig an die Verhältnisse des Einzelfalls angepasst werden. In einfachen Fällen können hierzu die Druckfeder 21 gewechselt oder Unterlegscheiben verwendet werden. Es wäre aber auch denkbar, anstelle der Querwand 22 eine in das obere Ende der oberen Nabe 11 einschraubbare, mit der Druckfeder 21 zusammenwirkende Stellschraube vorzusehen.The bias of the compression spring 21 in the closed state can be suitably adapted to the conditions of the case. In simple cases, the compression spring 21 can be replaced or washers used for this purpose. It would also be conceivable, instead of the transverse wall 22 to provide a screwed into the upper end of the upper hub 11, cooperating with the compression spring 21 screw.

Ein bevorzugtes Anwendungsgebiet der Erfindung sind Sauna- und/oder Baderaumtüren. Aber auch jede andere Tür, bei der eine selbstschließende Wirkung oder eine Pendelfunktion erwünscht ist, kommt in Frage.A preferred field of application of the invention are sauna and / or bath room doors. But any other door in which a self-closing effect or a pendulum function is desired, comes into question.
