Description

Rollenführung  roller guide
Die vorliegende Erfindung betrifft eine Rolienführung, insbesondere für eine Schiebetür, mit mindestens einer Laufrolle, die an einem Laufwagen drehbar ge- lagert ist und auf einem Boden einer Führungsschiene abrollt, wobei die Laufrolle von einer Schüeßposition in einen Öffnungsbereich verfahrbar ist. The present invention relates to a roller guide, in particular for a sliding door, with at least one roller which is mounted rotatably on a carriage and rolls on a bottom of a guide rail, wherein the roller is movable from a Schüeßposition in an opening region.
Die DE 24 28 593 offenbart einen Beschlag zum waagerechten Verschieben eines Flügels, wobei bei einem Bewegen des Flügels in die Schließposition zwei voneinander beabstandete Rollen gleichzeitig auf eine Rampe auflaufen. Dadurch wird der Schwung des Flügels gebremst, während beim Öffnen die Laufrollen die Rampen herunterrollen und beschleunigen. Die Rampen sind dabei als zusätzliche Bauteile ausgebildet, die auf eine Laufschiene aufgeschraubt sind. Dadurch ist die Montage vergleichsweise aufwändig und die Handhabung des Beschtages wegen der Vertikalbewegung des Flügels wenig komfortabel. DE 24 28 593 discloses a fitting for the horizontal displacement of a wing, wherein when moving the wing in the closed position two spaced-apart rollers accumulate simultaneously on a ramp. This slows down the swing of the sash while, when opened, the rollers roll down and accelerate the ramps. The ramps are designed as additional components which are screwed onto a running rail. As a result, the installation is relatively complex and the handling of the Beschmages because of the vertical movement of the wing little comfortable.
Die EP 478 938 offenbart eine Laufrollenführung für eine Aufzugsschiebetür, bei der eine hohe Laufruhe dadurch erreicht werden soll, dass die in der Ruheposition belasteten Bereiche beabstandet von den Laufflächen der Laufrolle in einem Öffnungsbereich sind. Hierfür sind Rampenstücke an der Laufschiene montiert, die den Flügel beim Verfahren in die Schließposition anheben. Dabei kann zwar eine Abflachung durch eine Belastung an dem elastischen Material der Laufrolle erreicht werden, allerdings wird an der Laufschiene ein zusätzliches Rampenstück montiert, was relativ aufwendig ist und die Handhabung beim Verschieben des Flügels erschwert. EP 478 938 discloses a roller guide for an elevator sliding door, in which a high level of smoothness is to be achieved in that the areas loaded in the rest position are spaced from the running surfaces of the roller in an opening area. For this purpose, ramp pieces are mounted on the running rail, which lift the wing in the process in the closed position. Although a flattening by a load on the elastic material of the roller can be achieved, however, an additional ramp piece is mounted on the running rail, which is relatively complicated and difficult to handle when moving the wing.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Rollenführung zu schaffen, die mit einfachen Mitteln die Bildung von Abflachungen an einer Laufrolle vermeidet und eine komfortable Handhabung gewährleistet. It is therefore an object of the present invention to provide a roller guide which avoids the formation of flats on a roller with simple means and ensures comfortable handling.
Diese Aufgabe wird mit einer Rollenführung mit den Merkmalen des Anspruches 1 gelöst. This object is achieved with a roller guide with the features of claim 1.
Erfindungsgemäß ist der Boden der Führungsschiene der Rollenführung so ge- staltet, dass die Anlagefläche der mindestens einen Laufrolle an dem Boden in der Schließposition in axiale Richtung der Drehachse der Laufrolle gegenüber . 9 dem Öffnungsbereich versetzt ist. Dadurch kann auf einfache Weise die Geometrie der Führungsschiene genutzt werden, um in der Schließposition eine andere Aniagefläche an der Laufrolle vorzusehen als im Öffnungsbereich. Dadurch kann eine umlaufende Lauffläche, die im Öffnungsbereich als Anlagefläche dient, in der Schließposition geschont werden, um Abplattungen zu vermeiden. Es ist nicht erforderlich, dass zusätzliche Rampen oder andere Bauteile an der Führungsschiene montiert werden, sondern der Boden der Führungsschiene wird durch entsprechende Formgebung so gestaltet, dass die Aniagefläche der Laufrolle in der Schließposition in axiale Richtung versetzt ist. Dies ermöglicht auch einen konti- nuierlichen Übergang ohne Sprünge, so dass eine hohe Lauf ruhe erreicht werden kann. According to the invention, the bottom of the guide rail of the roller guide is designed such that the contact surface of the at least one roller against the bottom in the closed position in the axial direction of the axis of rotation of the roller opposite , 9 is offset from the opening area. As a result, the geometry of the guide rail can be used in a simple manner to provide a different Aniagefläche on the roller in the closed position than in the opening area. As a result, a circumferential running surface, which serves as a contact surface in the opening area, can be spared in the closed position in order to avoid flattening. It is not necessary that additional ramps or other components are mounted on the guide rail, but the bottom of the guide rail is designed by appropriate shaping so that the Aniagefläche the roller is offset in the closed position in the axial direction. This also allows a continuous transition without jumps, so that a high degree of quietness can be achieved.
Gemäß einer bevorzugten Ausgestaltung ist die Drehachse der Laufrolle im Öffnungsbereich und in der Schiießposition relativ zu der Führungsschiene auf der gleichen Höhe angeordnet. Die Laufrolle verfährt somit nur in horizontaler Richtung und wird nicht in eine Schließposition angehoben bzw. abgesenkt. Für den Nutzer ist somit die Änderung der Lauffläche im Bereich der Schließposition nicht spürbar, da lediglich die Lauffläche an der Laufrolle gewechselt wird, aber kein Anheben oder Absenken der Laufrolle bei einer Bewegung zwischen einem Öff- nungsbereich und einer Schließposition erfolgt. According to a preferred embodiment, the axis of rotation of the roller in the opening area and in the Schiießposition is arranged relative to the guide rail at the same height. The roller thus moves only in the horizontal direction and is not raised or lowered in a closed position. For the user, therefore, the change of the running surface in the region of the closed position is not noticeable, since only the running surface on the roller is changed, but no raising or lowering of the roller takes place during a movement between an opening region and a closing position.
Vorzugsweise umfasst der Boden der Führungsschiene zwei keilförmig nach innen abfallende Schenkel. Dadurch kann die mindestens eine Laufrolle in der Führungsschiene zentriert verfahren werden. Die Schenkel können dabei in der Schließposition der Laufrolle einen anderen Winkel aufweisen als im Öffnungsbereich. Dadurch kann durch einfaches Verformen der Schenkel in dem Bereich, in dem die Laufrolle in der Schließposition angeordnet ist, ein Wechsel der Anlagefläche erfolgen. Der Winkel der Schenkel zur Horizontalen kann in einem Bereich zwischen 10° und 25° liegen, um eine ausreichende Zentrierung beim Bewegen der Laufrolle zu gewährleisten. Preferably, the bottom of the guide rail comprises two wedge-shaped inwardly sloping leg. As a result, the at least one roller can be moved centered in the guide rail. The legs can have a different angle in the closed position of the roller than in the opening area. This can be done by simply deforming the legs in the area in which the roller is arranged in the closed position, a change of the contact surface. The angle of the legs to the horizontal may be in a range between 10 ° and 25 ° to ensure sufficient centering when moving the roller.
Der Boden der Führungsschiene kann einen mittleren horizontalen ebenen Bereich zur Abstützung der Laufrolle aufweisen. Dieser Bereich kann zwischen den beiden Schenkeln angeordnet sein, so dass im Öffnungsbereich die geneigten Schenkel in Kontakt mit der Laufrolle und in der Schließposition ein mittlerer horizontal ausgerichteter Bereich die Anlagefläche bildet. Umgekehrt ist es möglich, auch in der Schließposition die Anlagefläche an den geneigten Schenkeln vorzu- sehen, während im Öffnungsbereich ein mittlerer horizontaler Abschnitt der Laufrolle bzw. der Führungsschiene die Anlagefläche ausbildet. The bottom of the guide rail may have a central horizontal planar area for supporting the roller. This area can be arranged between the two legs, so that in the opening area, the inclined legs in contact with the roller and in the closed position, a central horizontally oriented area forms the contact surface. Conversely, it is possible, even in the closed position, to provide the contact surface on the inclined limbs. see while in the opening area, a central horizontal portion of the roller or the guide rail forms the contact surface.
Die Laufrolle umfasst vorzugsweise mindestens einen zylinderförmigen Mittelab- schnitt, an den sich an gegenüberliegenden Seiten jeweils ein kegelstumpfförmi- ger Abschnitt anschließt. Der kegelstumpfförmige Abschnitt kann sich nach außen hin verjüngen, wobei wahlweise die kegelstumpfförmigen Abschnitte oder der mittlere zylinderförmige Mittelabschnitt eine Anlagefläche ausbildet, je nachdem, ob sich die Laufrolle in einem Öffnungsbereich oder in der Schließposition befin- det. The roller preferably comprises at least one cylindrical center section, to which a truncated cone-shaped section adjoins on opposite sides. The frusto-conical portion may taper outwardly, with either the frusto-conical portions or the central central cylindrical portion forming a locating surface, depending on whether the pulley is in an opening area or in the closed position.
Für eine einfache Hersteilung der Führungsschiene kann diese aus einem gebogenen Metallblech hergestellt sein, vorzugsweise einem Stahlblech. Die Roilenführung kann mehrere voneinander beabstandete Laufrollen umfassen, wobei für jede Laufrolle eine Schließposition und ein Öffnungsbereich an der Führungsschiene ausgebildet sind. Wenn der Abstand der Laufrollen geringer ist als der maximale Schiebeweg, verfährt eine der Laufrollen über die Schließposition der anderen Laufrolle. Dies ist jedoch problemlos möglich, da die Laufrolle sowohl in der Schließposition der anderen Laufrolle als auch im Öffnungsbereich auf derselben Höhe angeordnet ist Insofern merkt der Benutzer beim Überfahren der Schließposition keinen Unterschied. For a simple production of the guide rail, this can be made of a bent metal sheet, preferably a steel sheet. The Roilenführung may comprise a plurality of spaced-apart rollers, wherein for each roller a closed position and an opening portion are formed on the guide rail. If the distance of the rollers is less than the maximum sliding distance, one of the rollers moves beyond the closed position of the other roller. However, this is easily possible, since the roller is arranged both in the closed position of the other roller and in the opening area at the same height Insofar the user notices a difference when crossing the closed position.
Für eine geräuscharme Bewegung ist die mindestens eine Laufrolle aus einem elastischen Material hergestellt oder mit einem elastischen Material beschichtet, so das etwaige Unebenheiten ausgeglichen werden könne. Als elastisches Material kommt insbesondere Kunststoff und/oder Gummi zum Einsatz. For a low-noise movement, the at least one roller made of an elastic material or coated with an elastic material, so that any bumps could be compensated. Plastic and / or rubber are used in particular as elastic material.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles mit Bezug auf die beigefügten Zeichnungen näher erläutert. Es zeigen: The invention will be explained in more detail using an exemplary embodiment with reference to the accompanying drawings. Show it:
Figur 1 eine Seitenansicht auf ein Ausführungsbeispiel einer erfindungsgemäßen Rollenführung; Figure 1 is a side view of an embodiment of a roller guide according to the invention;
Figur 2 eine vergrößerte Ansicht der Rollenführung der Figur 1 ; Figure 2 is an enlarged view of the roller guide of Figure 1;
Figur 3 eine vergrößerte Detailansicht der Rollenführung der Figur 2. Eine Rollenführung 1 , insbesondere zur Lagerung einer Schiebetür, umfasst eine Führungsschiene 3, die an einem Möbelkorpus 2 festgelegt ist. Hierfür ist ein oberer Schenkel 6 der Führungsschiene 3 an einer Oberseite des Möbelkorpus 2 festgelegt. FIG. 3 shows an enlarged detail view of the roller guide of FIG. 2. A roller guide 1, in particular for supporting a sliding door, comprises a guide rail 3, which is fixed to a furniture carcass 2. For this purpose, an upper leg 6 of the guide rail 3 is fixed to an upper side of the furniture body 2.
Die Führungsschiene 3 umfasst einen vertikalen Schenkel 7, an dem ein abgewinkelter Boden 8 ausgebildet ist, an dem eine Laufrolle 5 verfahrbar gelagert ist. Benachbart zu dem Boden 8 ist ein weiterer Boden 9 für eine benachbart ange- ordnete Laufrolle ausgebildet. Es ist auch möglich, nur einen Boden 8 an der Führungsschiene 3 oder mehr als zwei Böden 8 bzw. 9 an einer Führungsschiene 3 vorzusehen. Dadurch können an der Führungsschiene 3 ein oder mehrere Flügel verfahrbar gelagert sein. Die Laufrolle 5 ist an einem Laufwagen 4 drehbar gelagert, wobei an dem Laufwagen 4 ein Flügel einer Schiebetür hängend gelagert ist. Über die Länge der Führungsschiene 3 verteilt können dabei mehrere Laufrollen 5 verfahrbar gelagert sein. Jede Laufrolle 5 besteht aus einem elastischen Material aus Kunststoff oder Gummi oder ist zumindest mit einer äußeren elastischen Beschichtung versehen, um nur wenig Laufgeräusche beim Abrollen zu erzeugen. Eine derartige elastische Beschichtung hat jedoch auch den Nachteil, dass bei einem längeren Stillstand einer Schiebetür leichte Abflachungen am (Laufprofii) der Rolle 5 entstehen. Es ist dadurch nicht auszuschließen, dass beim darauffolgenden Verfahren der Schiebtür leichte Klopfgeräusche hörbar werden. The guide rail 3 comprises a vertical leg 7, on which an angled bottom 8 is formed, on which a roller 5 is movably mounted. Adjacent to the floor 8, a further floor 9 is formed for an adjacently arranged roller. It is also possible to provide only one floor 8 on the guide rail 3 or more than two floors 8 and 9 on a guide rail 3. As a result, one or more wings can be movably mounted on the guide rail 3. The roller 5 is rotatably mounted on a carriage 4, wherein on the carriage 4, a wing of a sliding door is suspended. Distributed over the length of the guide rail 3 while several rollers 5 can be movably mounted. Each roller 5 is made of an elastic material made of plastic or rubber or is at least provided with an outer elastic coating to produce little noise when unrolling. However, such an elastic coating also has the disadvantage that slight flattening of the (roller profile) of the roller 5 occurs during a longer standstill of a sliding door. It can not be ruled out that slight knocking sounds will be heard during the subsequent movement of the sliding door.
Um Abflachungen zu vermeiden, die in einer Schließposition, an der Laufrolle 5 entstehen können, wechselt der Bereich der Anlagefläche beim Verfahren der Laufrolle 5 von einem Öffnungsbereich in eine Schließposition. Die Schließposition ist beispielsweise die Position, wenn sich der Flügel in einer geschlossenen Position befindet. Die Schließposition ist die Position, die von der Laufrolle 5 über eine lange Zeit im Betrieb eingenommen wird, wobei die Länge der Schließposition auch einige mm betragen kann. Der Öffnungsbereich ist beispielsweise derjenige Bereich, der beim Öffnen des Flügels einer Schiebetür bzw. durch das Rollen der Laufrolle 5 erreicht wird, wobei der Öffnungsbereich beabstandet von der Schließposition angeordnet ist. In den Figuren 2 und 3 ist der Bereich der Schließposition der Laufrolle 5 im Detail dargestellt. Der Boden 8 der Führungsschiene 3 umfasst einen mittleren horizontalen ebenen Bereich 18, der eine ebene Oberfläche 10 aufweist, die beabstandet von der Laufrolle 5 angeordnet ist. Zu jeder Seite des mittleren ebe- nen Bereiches 18 ist ein zur Horizontalen winklig geneigt angeordneter Schenkel 16 und 17 ausgebildet, wobei der Schenke! 16 an der Oberseite eine Anlagefläche 11 und der Schenkel 17 an der Oberseite eine Anlagefläche 12 ausbildet. In order to avoid flattening, which may occur in a closed position on the roller 5, the area of the contact surface changes during the movement of the roller 5 from an opening area to a closed position. The closed position is, for example, the position when the wing is in a closed position. The closing position is the position occupied by the roller 5 for a long time in operation, and the length of the closing position may be several mm. The opening area is, for example, that area which is reached when the leaf of a sliding door is opened or by the rollers of the roller 5, wherein the opening area is arranged at a distance from the closed position. In FIGS. 2 and 3, the area of the closed position of the roller 5 is shown in detail. The bottom 8 of the guide rail 3 comprises a central horizontal flat portion 18 which has a flat surface 10 spaced from the roller 5. On each side of the middle level region 18, a leg 16 and 17 which is inclined at an angle to the horizontal is formed, the tavern! 16 at the top of a contact surface 11 and the legs 17 at the top of a contact surface 12 is formed.
Die Laufrolle 5 umfasst einen zylinderförmigen Mittelabschnitt 14, der an gegen- überliegenden Seiten integral mit einem kegelstumpfförmigen Abschnitt 15 ausgebildet ist. Der kegelstumpfförmige Abschnitt 15 auf der linken Seite liegt auf der Anlagefläche 11 und auf der gegenüberliegenden Seite auf der Anlagefläche 12 auf. Eine Umfangsfläche 13 an dem Mittelabschnitt 14 ist beabstandet von der Oberfläche 10 angeordnet. Dadurch wird vermieden, dass in der Schüeßposition an der Umfangsfläche 13 des Mittelabschnitts 14 ein Druckpunkt in Folge von einer statischen Dauerbelastung gebildet ist, der zu Abflachungen führt. The roller 5 comprises a cylindrical central portion 14 formed integrally with a frusto-conical portion 15 on opposite sides. The frusto-conical portion 15 on the left side rests on the abutment surface 11 and on the opposite side on the abutment surface 12. A peripheral surface 13 at the central portion 14 is spaced from the surface 10. This avoids that in the Schüeßposition on the peripheral surface 13 of the central portion 14, a pressure point is formed in consequence of a static continuous load, which leads to flattening.
Wenn die Laufrolle 5 aus der in den Figuren 2 und 3 gezeigten Position in den Öffnungsbereich bewegt wird, ändert sich der Winkel der Schenkel 16 und 17 zur Horizontalen, so dass im Öffnungsbereich die Umfangsfläche 13 des Mittelabschnitts 14 auf der Oberfläche 10 des mittleren ebenen Bereiches 18 der Führungsschiene 3 aufliegt. Dadurch wechselt die Anlagefläche der Laufrolle 5 bei einem Übergang zwischen Schließposition und Öffnungsbereich. Die Anlagefläche wird quasi in axiale Richtung der Drehachse der Laufrolle 5 verschoben, wo- bei die Laufrolle 5 beim Abrollen an dem Boden 8 der Führungsschiene 3 horizontal auf einer Höhe bleibt. in dem gezeigten Ausführungsbeispiel befindet sich die Laufrolle 5 in der When the roller 5 is moved from the position shown in Figures 2 and 3 into the opening area, the angle of the legs 16 and 17 to the horizontal changes, so that in the opening area, the peripheral surface 13 of the central portion 14 on the surface 10 of the central planar area 18 of the guide rail 3 rests. As a result, the contact surface of the roller 5 changes at a transition between the closed position and opening area. The abutment surface is displaced, as it were, in the axial direction of the axis of rotation of the roller 5, with the roller 5, when unrolling, remaining horizontally at a height at the bottom 8 of the guide rail 3. in the embodiment shown, the roller 5 is in the
Schüeßposition in Kontakt mit der Führungsschiene 8 an den abgewinkelten Schenkeln 16 und 7, während im Öffnungsbereich die Laufrolle 5 auf der ebenen mittleren Umfangsfläche 13 abrollt. Es ist natürlich umgekehrt auch möglich, die Führungsschiene 3 so auszubilden, dass in der Schließposition die mittlere Umfangsfläche 13 an der Oberfläche 10 anliegt, während die Oberfläche an den kegelstumpfförmigen Abschnitten 15 der Laufrolle 5 beabstandet von dem Boden 8 der Führungsschiene 3 angeordnet ist. Dann kann beim Verfahren der Laufrolle 5 in den Öffnungsbereich die in den Figuren 2 und 3 gezeigte Position erreicht werden, in der der mittlere Bereich beabstandet angeordnet ist und die geneigt angeordneten Anlageflächen 1 1 und 12 die Gewichtskräfte durch die Laufrolle 5 aufnehmen. Schüeßposition in contact with the guide rail 8 at the angled legs 16 and 7, while in the opening area, the roller 5 rolls on the flat central peripheral surface 13. Conversely, it is of course also possible, the guide rail 3 in such a way that in the closed position, the central peripheral surface 13 abuts the surface 10, while the surface at the frusto-conical portions 15 of the roller 5 is spaced from the bottom 8 of the guide rail 3. Then, in moving the roller 5 into the opening portion, the position shown in Figs. 2 and 3 can be achieved, in which the central portion is spaced and inclined arranged contact surfaces 1 1 and 12 absorb the weight forces by the roller 5.
Die Führungsschiene 3 ist vorzugsweise durch Biegen eines Stahlbleches herge- stellt, wobei der Übergang zwischen Schließposition und Öffnungsbereich durch ein Biegen der Schenkel 16 und 17, Prägungen oder durch andere Mittel erreicht werden kann. Die Anlageflächen für die Laufrolle 5 sind dann integral mit der Führungsschiene 3 an einer Oberfläche ausgebildet. Der Übergangsbereich zwischen der Schließposition und dem Öffnungsbereich kann dabei auch in einem gewis- sen Bereich überschneidend ausgebildet sein, d.h. die Laufrolle ist sowohl mit den Anlageflächen der Schließposition als auch mit den Anlageflächen in dem Öffnungsbereich in Kontakt mit der Führungsschiene 3. The guide rail 3 is preferably made by bending a steel sheet, and the transition between the closing position and the opening portion can be achieved by bending the legs 16 and 17, embossing or by other means. The contact surfaces for the roller 5 are then formed integrally with the guide rail 3 on a surface. The transition region between the closed position and the opening region can also be designed to overlap in a certain area, i. the roller is in contact with the guide rail 3 both with the contact surfaces of the closing position and with the contact surfaces in the opening region.
Gemäß einer weiteren Ausführungsform ist es möglich, die Laufrolle 5 zylindrisch auszubilden und die Anlagefläche am Umfang der Laufrolle 5 durch Prägungen zu bestimmen, beispielsweise kann in einer Schließposition eine Aussparung oder Absenkung in der Führungsschiene ausgebildet sein, die sich nur über einen Teil der Breite der Laufrolle 5 erstreckt. Im Bereich der Absenkung bzw. Ausnehmung ist dann kein Kontakt, so dass dieser Bereich dann in einem Öffnungsbe- reich die Lauffläche der Laufrolle 5 ausbilden kann. According to a further embodiment, it is possible to form the roller 5 cylindrical and to determine the contact surface on the circumference of the roller 5 by imprints, for example, may be formed in a closed position, a recess or depression in the guide rail, which is only over part of the width of Roller 5 extends. In the region of the countersink or recess there is no contact, so that this area can then form the running surface of the roller 5 in an opening area.
