Description

Drehlager für einen Flügel, insbesondere Scherenlager bestehend aus einem rahmenseitigen Lagerbock und einer flügelseitigen Scharnierhülse. Lagerbock und Scharnierhülse werden von einem Drehlagerbolzen axial durchsetzt. Um den Drehlagerbolzen in den Bohrungen zu fixieren, sind bereits verschiedene Ausgestaltungen getroffen worden. Insbesondere Federelemente, die im Lagerbock angeordnet sind und in Umfangsnuten des Drehlagerbolzens eingreifen, sind weit verbreitet. Andere Lösungen sehen Stellelemente vor, die in Umfangsnuten verschraubt oder geklipst werden.Swivel bearing for a wing, in particular scissors bearing consisting of a frame-side bracket and a wing-side hinge sleeve. Bearing block and hinge sleeve are penetrated axially by a pivot bearing pin. In order to fix the pivot pin in the holes, various configurations have already been made. In particular, spring elements which are arranged in the bearing block and engage in circumferential grooves of the pivot bearing pin are widely used. Other solutions provide adjusting elements that are screwed or clipped in circumferential grooves.

Die erstgenannten Federelemente, z.B. entsprechend der DE 2343507 A1 , DE 9016894 U1 , sind aufwendig geformte Drahtgebilde, die in dem Lagerbock festgesetzt werden müssen. Es sind daher zumindest zwei Bauteile, nämlich der Lagerbock und das Sicherungselement vorzusehen und diese miteinander zu verbinden. Vielfach (z.B. DE 1833909 U1 ) werden pro Lagerauge des Lagerbocks ein Federelement vorgesehen, um die Symmetrie zu wahren und eine Vormontagestellung zu erreichen, in welcher der Drehlagerbolzen teilweise in einer der Lageraugen fixiert ist.The first-mentioned spring elements, eg according to DE 2343507 A1 . DE 9016894 U1 , are elaborate shaped wireforms that must be fixed in the bearing block. There are therefore at least two components, namely to provide the bearing block and the fuse element and to connect them together. Many times (eg DE 1833909 U1 ) are provided per bearing eye of the bearing block, a spring element to maintain the symmetry and to achieve a pre-assembly in which the pivot pin is partially fixed in one of the bearing eyes.

Nachteilig ist dabei, dass der Drehlagerbolzen als Drehteil ausgestaltet werden muss, um die umlaufenden Nuten passgenau anbringen zu können. Hierzu wäre auf die DE 1584006 A1 zu verweisen. Einige der bekannten Ausgestaltungen ( DE 19514867 A1 , DE 29605809 U1 oder EP 2265785 B1 ) haben zudem keinen zylindrischen Mantelumfang des Drehlagerbolzens um ein Mitdrehen desselben zu vermeiden. Die Federelemente sind kostenintensiv aufgrund ihrer komplizierten Formgebung und lassen sich nur schlecht maschinell verarbeiten.The disadvantage here is that the pivot bearing pin must be designed as a rotating part in order to attach the circumferential grooves accurately. This would be on the DE 1584006 A1 to refer. Some of the known embodiments ( DE 19514867 A1 . DE 29605809 U1 or EP 2265785 B1 ) also have no cylindrical shell circumference of the pivot bearing bolt to the same to avoid turning. The spring elements are costly due to their complicated shape and can only be processed by machine.

Aus der DE 813665 B ist ein Drehlager bekannt, bei dem der Drehlagerbolzen eines Fensters aus einer dünnwandigen gerollten Feder besteht, welche in dem Gelenk als Bolzen wirksam ist und in Bohrungen des flügelseitigen und rahmenseitigen Bandes eingreift. Die axiale Fixierung wird über eine Vorspannung der Hülse erreicht. Dies setzt zum einen eine hohe Fertigungsgenauigkeit der Feder und der Bänder zum anderen voraus, die eine Schwenkbewegung zulassen soll, aber gleichzeitig sicher fixiert sein soll. Eine formschlüssige Fixierung ist nicht vorgesehen.From the DE 813665 B a pivot bearing is known in which the pivot pin of a window consists of a thin-walled rolled spring, which is effective in the joint as a bolt and engages in bores of the wing-side and frame-side band. The axial fixation is achieved via a bias of the sleeve. This requires on the one hand a high manufacturing accuracy of the spring and the bands to the other, which should allow a pivoting movement, but at the same time should be securely fixed. A positive fixation is not provided.

Die DE 29504910 U1 offenbart einen Drehlagerbolzen, der abschnittsweise als Federelement gestaltet ist. Hierzu ist ein End-Teilabschnitt des Drehlagerbolzens verjüngt ausgeführt und zusammen mit einem über den zylindrischen Bolzenabschnitt vorragenden Rastkopf exzentrisch versetzt. Der End-Teilabschnitt ist durch eine Einschnürung mit dem zylindrischen Bolzenabschnitt verbunden, so dass der End-Teilabschnitt mit dem Rastkopf federnd ausweichen kann, wenn dieser die Gelenkhülsen durchdringt und schließlich an einem Axialende derselben verrastet. Die Herstellung des Drehlagerbolzens ist daher schwierig und kostspielig, da die Schaffung des exzentrischen End-Teilabschnitts aufwendig ist.The DE 29504910 U1 discloses a pivot pin, which is designed in sections as a spring element. For this purpose, an end portion of the pivot bearing pin is tapered and executed offset eccentrically together with a projecting beyond the cylindrical pin portion locking head. The end portion is connected by a constriction with the cylindrical bolt portion, so that the end portion can escape resiliently with the locking head when it penetrates the joint sleeves and finally locked at an axial end thereof. The production of the pivot bearing pin is therefore difficult and expensive, since the creation of the eccentric end portion is expensive.

Die DE 9410858 U1 hat einen Scharnierbolzen zum Gegenstand, der einen gegenüber einem Schaft einen durchmesservergrößerten Kopf trägt und diametral dazu mit einer abgesetzten Axial-Bohrung versehen ist, die nahe des Kopfes von einer Querbohrung geschnitten wird. Die Axial-Bohrung ist als Stufenbohrung mit zwei Durchmessern ausgelegt, bei der die Querbohrung in einem Bereich mit kleinerem Durchmesser liegt. In diesem kleineren Durchmesser ist ein drahtförmiges Sicherungselement aufgenommen, welches an der Querbohrung mittels einer Ausprägung fixiert ist. Diese Ausgestaltung ist durch das Anbringen der Bohrungen mit unterschiedlichem Durchmesser sehr komplex und kostenintensiv in der Herstellung. Auch ist die prozesssichere Herstellung in großen Stückzahlen und bei Sicherheitsbedenken aufgrund des hohen Flügelgewichtes bei Fenstern oder Türen fragwürdig.The DE 9410858 U1 The object of the invention is a hinge pin which carries an enlarged diameter head relative to a shank and which is diametrically provided with a stepped axial bore cut by a transverse bore near the head. The axial bore is designed as a stepped bore with two diameters in which the transverse bore is located in a region of smaller diameter. In this smaller diameter, a wire-shaped securing element is received, which is fixed to the transverse bore by means of an expression. This embodiment is very complex and cost-intensive to manufacture by mounting the holes with different diameters. Also, the process-reliable production in large numbers and security concerns due to the high sash weight in windows or doors is questionable.

Aufgabe ist es daher, ein Drehlager bereitzustellen, welches kostengünstig mit wenigen Bauteilen herstellbar ist und die axiale Fixierung sicherstellt.Task is therefore to provide a pivot bearing, which is inexpensive to produce with few components and ensures the axial fixation.

Die Aufgabe wird zunächst dadurch gelöst, dass der Drehlagerbolzen als Hülse mit einer axialen Bohrung aus einem Blechabschnitt gebildet ist. Die Hülse lässt sich durch Rollen aus dem Blechabschnitt herstellen und vermeidet daher zunächst die aufwendige Herstellung als Drehteil.The object is initially achieved in that the pivot bearing pin is formed as a sleeve with an axial bore of a sheet metal section. The sleeve can be produced by rolling from the sheet metal section and therefore initially avoids the costly production as a turned part.

Eine Weiterbildung sieht vor, dass die axiale Bohrung das Sicherungselement aufnimmt, so dass dieses nicht an dem Lagerbock oder dem Lageraugenteil vorgesehen werden muss.A further embodiment provides that the axial bore receives the securing element, so that it does not have to be provided on the bearing block or the bearing eye part.

Dabei kann nach einer Weiterbildung das Sicherungselement aus einem, den Drehlagerbolzen durchsetzenden Stift bestehen, der an einem Ende einen T-förmigen Anschlag und am anderen Ende ein radial wirkendes Rastelement bildet.In this case, according to a development, the securing element consists of a, the pivot pin passing through pin which forms a T-shaped stop at one end and a radially acting locking element at the other end.

Eine kostengünstige Ausgestaltung sieht vor, dass der Drehlagerbolzen eine Spannhülse ist. Diese sind handelsüblich in verschiedenen Abmessungen kostengünstig erhältlich.An inexpensive embodiment provides that the pivot bearing pin is a clamping sleeve. These are commercially available in different dimensions cost.

Um das zusätzlich anzufertigende Sicherungselement einsparen zu können ist vorgesehen, dass die Hülse an zumindest einem Ende omega-förmig abgespreitzte Rastlappen ausbildet, die über den Außenumfang überstehen, so dass die Rasthülse das elastische Sicherungselement selbst bildet.In order to be able to save the additional securing element to be produced, it is provided that the sleeve forms omnidirectionally shaped locking tabs at at least one end, which protrude beyond the outer circumference, so that the detent sleeve forms the elastic securing element itself.

In der Fig. 1 ist ein rahmenseitiger Lagerbock mit 1 bezeichnet. An zwei Lageraugen 3, 4 sind koaxiale Lagerbohrungen 5, 6 vorgesehen. Diese werden von dem Drehlagerbolzen 7 durchsetzt. Dieser ist ausweislich in der Fig. 3 als Spannhülse gestaltet, die aus einem dünnwandigen Blechabschnitt durch einen Rollvorgang hergestellt wird. Der Drehlagerbolzen 7 erhält dadurch einen zylindrischen Mantel 8 und eine Kerbe 9. Die Kerbe 9 entsteht durch den nicht vollständig geschlossenen Mantel 8 und ist in der Fig. 1 an dem Lagerbock 1 einer in die Lageraugen 3, 4 vorragenden Nase 10 zugeordnet. Dadurch ist der Drehlagerbolzen 7 drehfest an dem Lagerbock 1 gelagert. Die Nase 10 verhindert neben einer unerwünschten Verdrehung auch eine elastische Verformung des Drehlagerbolzens 7. Die Gestaltung des Drehlagerbolzens 7 als Spannhülse bedingt eine zentrische Bohrung 11.In the Fig. 1 is a frame-side bracket designated 1. Coaxial bearing bores 5, 6 are provided on two bearing eyes 3, 4. These are penetrated by the pivot pin 7. This is evidently in the Fig. 3 designed as a clamping sleeve, which is made of a thin-walled sheet metal section by a rolling process. The pivot bearing pin 7 is replaced by a cylindrical shell 8 and a notch 9. The notch 9 is formed by the not completely closed shell 8 and is in the Fig. 1 assigned to the bearing block 1 of a projecting into the bearing eyes 3, 4 nose 10. As a result, the pivot bearing pin 7 is rotatably mounted on the bearing block 1. The nose 10 prevents not only an undesirable rotation but also an elastic deformation of the pivot bearing pin 7. The design of the pivot bearing pin 7 as a clamping sleeve requires a central bore eleventh

In der Bohrung 11 ist in einem ersten Ausführungsbeispiel ein Sicherungselement 12 aufgenommen. Dieses besteht aus einem den Drehlagerbolzen 7 durchsetzenden Stift 13, der an einem Ende 14 einen T-förmigen Anschlag 15 und am anderen Ende 16 ein radial wirkendes Rastelement 17 bildet.In the bore 11, a securing element 12 is received in a first embodiment. This consists of a pivot pin 7 passing through the pin 13 which forms a T-shaped stop 15 at one end 14 and a radially acting locking element 17 at the other end 16.

Der Stift 13 ist mit einem auf den Durchmesser der Bohrung 11 abgestimmten Schaft 18 versehen. Der Schaft 18 bildet eine Teillänge des Stiftes 13 und geht in eine schmaler geschnittene Zunge 19 über. Die Zunge 19 endet in dem Rastelement 17, welches als Rasthaken ausgebildet ist. Die Zunge 19 ist so bemessen, dass das Rastelement 17 bei einer elastischen Verformung der Zunge 19 in der Bohrung 11 aufgenommen ist.The pin 13 is provided with a shaft 18 adapted to the diameter of the bore 11. The shaft 18 forms a partial length of the pin 13 and merges into a narrower-cut tongue 19. The tongue 19 terminates in the latching element 17, which is designed as a latching hook. The tongue 19 is dimensioned so that the locking element 17 is received in an elastic deformation of the tongue 19 in the bore 11.

Zudem kann, um die elastische Verformung der Spannhülse klein zu halten, der Stift 13 aus einem flachrechteckigen Querschnitt durch Stanzen hergestellt werden. Die Stärke des Materials zur Herstellung des Stiftes 13 ist dabei auf die Kerbe 9 angepasst, so dass der Stift 13 teilweise in die Kerbe 9 eintaucht. Kommt es infolge einer höheren Belastung zu einer elastischen Verformung der Spannhülse, die ein Schließen der Kerbe 9 zur Folge hat, wird dies dadurch verhindert und das Sicherungselement 12 durch die freien Enden der Spannhülse in seiner Lage festgeklemmt. Diese Klemmwirkung steigt mit der Belastung und der Verformung, so dass die Verbindung selbsthelfend ist. Da die größte Belastung auf den Drehlagerbolzen 7 zu erwarten ist, wenn der Flügel um 90° gegenüber den Rahmen verschwenkt ist, kann die Lage des Rastelementes 17 so gewählt werden, dass dieses in Richtung der zu erwartenden Verformung liegt, so dass der Eingriff des Rastelementes 17 sogar verstärkt wird. Abweichend von Fig. 1 ist daher in der Fig. 4 eine Ausrichtung der Nase 10 gewählt, die quer zu einem Befestigungsflansch 20 liegt. Da diese Ausgestaltung jedoch unterschiedliche Lagerböcke 1 für nach rechts und links öffnende Flügel zur Folge hat, kann eine solche Anordnung nur dort vorteilhaft sein, wo die Anordnung entsprechend ausgestalteter Lagerböcke 1 unausweichlich ist.In addition, in order to keep the elastic deformation of the clamping sleeve small, the pin 13 are made of a flat rectangular cross section by punching. The thickness of the material for the production of the pin 13 is adapted to the notch 9, so that the pin 13 is partially immersed in the notch 9. If it comes as a result of a higher load to an elastic deformation of the clamping sleeve, which has a closing of the notch 9 result, this is prevented and the securing element 12 clamped by the free ends of the clamping sleeve in position. This clamping action increases with the load and the deformation, so that the connection is self-helping. Since the greatest load on the pivot bearing pin 7 is to be expected when the wing is pivoted by 90 ° relative to the frame, the position of the locking element 17 can be selected so that it lies in the direction of the expected deformation, so that the engagement of the locking element 17 is even reinforced. Deviating from Fig. 1 is therefore in the Fig. 4 chosen an orientation of the nose 10, which is transverse to a mounting flange 20. However, since this embodiment has different bearing blocks 1 for right and left opening wings result, such an arrangement can be advantageous only where the arrangement of appropriately designed bearing blocks 1 is inevitable.

Um das zusätzlich anzufertigende Sicherungselement 12 einsparen zu können, ist nach Fig. 5 in einem weiteren Ausführungsbeispiel vorgesehen, dass der Drehlagerbolzen 7, also die Spannhülse, an zumindest einem Ende einen tangential verlaufenden abgespreizten Rastlappen 21 oder 22 ausbildet, der über den Außenumfang 23 übersteht, so dass der Drehlagerbolzen 7 das elastische Sicherungselement 12 selbst bildet. Um die elastischen Eigenschaften der Rastlappen 21, 22 beeinflussen zu können ist ein Freischnitt vorgesehen, der die Rastlappen 21, 22 abschnittsweise abtrennt. Es können auch zwei Rastlappen vorgesehen sein.To be able to save the additionally manufactured securing element 12, is after Fig. 5 provided in a further embodiment that the pivot bearing pin 7, so the clamping sleeve, at least one end forms a tangentially extending splayed locking tabs 21 or 22 which projects beyond the outer periphery 23, so that the pivot bearing pin 7 forms the elastic securing element 12 itself. In order to influence the elastic properties of the latching tabs 21, 22, a cutout is provided, which separates the latching tabs 21, 22 in sections. It can also be provided two locking tabs.

Um im Wartungsfalle eine Entnahme des Drehlagerbolzens sicher zu stellen ist ein Werkzeug vorgesehen, welches in die Bohrung 11 eingreift und den Rastlappen 21 oder 22 elastisch zurückformt.In order to ensure a removal of the pivot bearing bolt in case of maintenance, a tool is provided which engages in the bore 11 and the locking tabs 21 or 22 elastically deforms.

Es ist ersichtlich, dass die Gestaltung des Drehlagerbolzens 7 in der vorbeschriebenen Art eine deutliche Materialeinsparung mit sich bringt. Zudem sind funktionelle Komponenten mit der so geschaffenen Raumform realisierbar. Die Kerbe 9 kann zusammen mit in der Bohrung einer hier nicht dargestellten Scharnierhülse Rastelementen Eingriff bieten, welche verschiedene Schwenkstellungen des Flügels relativ zum Rahmen kennzeichnen. Schließlich wirkt die Spannhülse noch elastisch und kann daher harte Stöße in Grenzen elastisch abfedern.It can be seen that the design of the pivot bearing pin 7 in the manner described above brings a significant material savings. In addition, functional components can be realized with the spatial form thus created. The notch 9 can provide locking elements together with in the bore of a hinge sleeve, not shown here, which mark different pivot positions of the wing relative to the frame. Finally, the clamping sleeve still acts elastic and can therefore absorb hard shock elastic limits.
