Abstract

For reasons of space, in pieces of furniture which can be closed, in particular cupboards 1, swinging-sliding doors 9 are used for closure. The cupboards 1 have in this case a shaft 3 which is mounted perpendicularly to the sliding direction opposite the opening side of the body 2 and which is provided with at least two toothed pinions 12 which are arranged at a spacing from one another and engage in corresponding racks 10, 11 connected rigidly to the door 9. At the same time, these racks 10, 11 are mounted slidably on the shaft 3 transversely to its longitudinal axis. In order to obtain a particularly good guide for the door 9, the rails 10 provided with rows of teeth 11 are designed at least on their opposite longitudinal edges 15, 16 as guide rails for rollers 8 of carriages 6 connected rigidly to the shaft 3. <IMAGE>

Description

Es sind bereits mit einer Dreh-Schiebetür verschließbare Schränke bekannt, welche, gegenüber der Öffnungsseite des Korpus eine senkrecht zur Schieberichtung drehbar gelagerte Welle aufweisen. Dabei ist die Welle mit mindestens zwei im Abstand untereinander angeordneten Zahnritzeln versehen, welche in mit der Tür fest verbundene entsprechende Zahnstangen eingreifen. Außerdem sind diese Zahnstangen an der Welle quer zu deren Längsachse verschiebbar gelagert, vgl. DE-A-3300189. Bei mit solchen Beschlägen versebenen Schränken kann die Tür in einer Dreh-Schiebebewegung geöffnet und in ihrer Offenstellung innerhalb oder außerhalb der Seitenwand des Schrankes plaziert werden, so daß sich nur ein sehr geringer Platzbedarf ergibt. Bei bekannten Ausführungsformen dieser Art ist die Führung für die Tür, insbesondere bei schweren Schränken, jedoch unzureichend.Cabinets lockable with a rotating sliding door are already known, which, opposite the opening side of the body, have a shaft rotatably mounted perpendicular to the sliding direction. The shaft is provided with at least two toothed pinions which are arranged at a distance from one another and which engage in corresponding toothed racks which are firmly connected to the door. In addition, these racks are slidably mounted on the shaft transversely to its longitudinal axis, cf. DE-A-3300189. In cabinets with such fittings the door can be opened in a rotating and sliding movement and placed in its open position inside or outside the side wall of the cabinet, so that there is only a very small space requirement. In known embodiments of this type, however, the guidance for the door, especially in the case of heavy cupboards, is inadequate.

Um diesen Nachteil zu beseitigen, sind erfindungsgemäß bei einem Möbelstück in der oben beschriebenen Art mit Zahnreihen versehene Schienen mindestens an ihren entgegengesetzt liegenden Längskanten als Führungsschienen für Rollen von mit der Welle fest verbundenen Laufwagen ausgebildet. Durch die Verwendung der Laufwagen, welche mit zwei oder mehr Rollen versehen sind, ergibt sich eine einwandfreie und relativ breite Führung für die Tür, so daß auch bei schweren Türen ein einseitiges Absinken nicht zu befürchten ist.In order to eliminate this disadvantage, according to the invention rails are provided with rows of teeth in a piece of furniture in the manner described above, at least on their opposite longitudinal edges as guide rails for rollers of carriages firmly connected to the shaft. The use of the carriages, which are provided with two or more rollers, results in a flawless and relatively wide guidance for the door, so that a one-sided sinking is not to be feared even with heavy doors.

Vorzugsweise bestehen die Laufwagen aus einem mit der Welle verbundenen Rollenträgern und zwei oder mehr Rollen. Dabei sind zweckmäßig an der Welle Haltelaschen vorgesehen, an denen die Rollenträger in Achsrichtung verschiebbar befestigt sind. Auf diese Weise ist es möglich, beim Einbau des Beschlages Ungenauigkeiten auszugleichen und vor allem eine spielfreie Verbindung der Teile zu erreichen. Um die Verbindung zwischen der Haltelasche und den Rollenträgern trotz der Höhenverstellbarkeit ausreichend zu sichern, sind die Langlöcher aufweisenden Haltelaschen und die Rollenträger mit ineinander greifenden Rippen versehen.The carriages preferably consist of a roller carrier connected to the shaft and two or more rollers. In this case, retaining tabs are expediently provided on the shaft, on which the roller carriers are fastened so as to be displaceable in the axial direction. In this way it is possible to compensate for inaccuracies when installing the fitting and, above all, to achieve a play-free connection of the parts. In order to adequately secure the connection between the retaining bracket and the roller carriers despite the height adjustability, the retaining tongues with elongated holes and the roller carriers are provided with interlocking ribs.

Da bei Verwendung üblicher Zahnstangen Ruckbewegungen beim Verschieben nicht auszuschließen sind, werden die Zahnreihen nach einem weiteren Merkmal der Erfindung und die in sie eingreifenden Zahnritzel quergeteilt, wobei die Zähne der Teilreihen und der Teilritzel geringfügig gegeneinander versetzt sind. Dadurch wird ein fortlaufender Eingriff der Zähne erreicht, wodurch zusätzlich das Spiel verringert wird.Since, when using conventional toothed racks, jerking movements during displacement cannot be ruled out, the rows of teeth are cross-divided according to a further feature of the invention and the toothed pinions engaging in them, the teeth of the partial rows and the partial pinion being slightly offset from one another. This results in a continuous engagement of the teeth, which also reduces the game.

Zur Vereinfachung der Herstellung und zur Erleichterung der Montage sind die Schienen zweckmäßig zweiteilig, wobei ein mit der Tür verbindbares Teil als Profilschiene und das andere als Zahnstange ausgebildet ist. Zweckmäßig ist die Zahnstange in die Profilschiene einschiebbar und kann dann mit dieser zusätzlich verschraubt werden. Die Profilschienen weisen eine Lauffläche für die Rollen und einen Führungsrand auf, so daß ein sicheres Halten der Tür an den Laufwagen gewährleistet ist. Um die Schienen sowohl für die Anbringung oben und unten als auch bei links und rechts zu öffnenden Türen verwenden zu können, sind diese längssymmetrisch ausgebildet. Dabei kann auch zusätzlich zwischen zwei Schienen eine dritte angeordnet werden, welche an beiden Seiten von Laufwagen umgriffen wird.To simplify manufacture and to facilitate assembly, the rails are expediently in two parts, one part which can be connected to the door being designed as a profile rail and the other being designed as a toothed rack. The rack can expediently be pushed into the profile rail and can then be additionally screwed to it. The profile rails have a running surface for the rollers and a guide edge, so that a secure holding of the door on the carriage is guaranteed. In order to be able to use the rails for top and bottom mounting as well as for doors opening on the left and right, they are longitudinally symmetrical. In this case, a third can also be arranged between two rails, which is encompassed by carriages on both sides.

Am Korpus 2 eines Schrankes 1 ist eine Welle 3 mittels mehrerer Beschlagteile 4 drehbar gelagert. An dieser Welle sind im Abstand untereinander Haltelaschen 5 angeschweißt, welche zur Befestigung von Laufwagen 6 dienen. Diese bestehen aus einem Rollenträger 7, welcher mit der Haltelasche 5 verschraubt ist und jeweils zwei Rollen 8 aufweist. An der Tür 9 sind in einem den Laufwagen 6 entsprechenden Abstand zwei Schienen 10 befestigt, welche auf ihren der Welle 3 zugewandten Flächen mit Zahnreihen 11 versehen sind. Auf der Höhe derselben sind an der Welle 3 in die Zahnreihen eingreifende Zahnritzel 12 befestigt.A shaft 3 is rotatably mounted on the body 2 of a cabinet 1 by means of a plurality of fitting parts 4. On this shaft holding tabs 5 are welded at a distance from each other, which are used to fasten the carriage 6. These consist of a roller carrier 7, which is screwed to the holding bracket 5 and each has two rollers 8. On the door 9 two rails 10 are attached at a distance corresponding to the carriage 6, which are provided with rows of teeth 11 on their surfaces facing the shaft 3. At the same level, pinions 12 engaging in the rows of teeth are attached to the shaft 3.

Die Schienen 10 sind zweiteilig ausgebildet, wobei der eine Schienenteil als Zahnstange 13 und der andere als Profilschiene 14 ausgebildet sind. Wie die Querschnitte in den Fign. 3 und 4 erkennen lassen, kann die Zahnstange 13 in die Profilschiene 14 eingeschoben und dann mit ihr, beispielsweise durch Verschraubung, verbunden werden. Die Profilschienen 14 weisen für die Rollen 8 der Laufwagen 6 Laufflächen 15 auf und sind auf ihrer von der Tür 9 abgewandten Seite mit einem Führungsrand 16 versehen. Um die Schienen sowohl unten als auch oben sowie an rechts und links zu öffenden Türen verwenden zu können, sind sie längssymmetrisch aufgebaut, so daß die Profilschiene 14 an beiden Längskanten Laufflächen 15 und Führungsränder 16 aufweist.The rails 10 are formed in two parts, one rail part being designed as a toothed rack 13 and the other as a profiled rail 14. As the cross sections in Figs. 3 and 4 show, the rack 13 can be inserted into the profile rail 14 and then with it, for example by screwing, get connected. The profile rails 14 have 6 treads 15 for the rollers 8 of the carriages and are provided with a guide edge 16 on their side facing away from the door 9. In order to be able to use the rails both below and above as well as on doors that can be opened on the right and left, they are constructed in a longitudinally symmetrical manner, so that the profile rail 14 has running surfaces 15 and guide edges 16 on both longitudinal edges.

Wie Fig. 2 erkennen läßt, sind die Zahnreihen 11 in zwei untereinander liegende Reihen 17 und 18 und die Ritzel 12 ebenfalls quergeteilt. Die Zahnreihen 17 und 18 und die beiden Teilritzel 19 und 20 weisen eine geringe Versetzung der Zähne zueinander auf, um einen möglichst ruhigen Lauf zu gewährleisten.As can be seen in FIG. 2, the rows of teeth 11 are also cross-divided into two rows 17 and 18 lying one below the other and the pinions 12. The rows of teeth 17 and 18 and the two pinion gears 19 and 20 have a slight offset of the teeth to one another in order to ensure the smoothest possible running.

Wie Fig. 2 erkennen läßt, sind die Haltelaschen 5 mit Langlöchern 21 versehen, so daß die Rollenträger 7 in Längsrichtung der Welle 3 um ein geringes Maß verschoben werden können. Dadurch ist es einerseits möglich, Ungenauigkeiten auszugleichen und andererseits kann man das Spiel zwischen den Rollen 8 und den Laufflächen 15 der Profilschiene 14 genau einstellen. Um die Höheneinstellung der Haltelaschen 5 und der Rollenträger 7 gegeneinander abzusichern, sind die aneinander liegenden Flächen der Teile in nicht dargestellter Weise mit Querrippen versehen.As can be seen in FIG. 2, the retaining tabs 5 are provided with elongated holes 21 so that the roller carriers 7 can be displaced by a small amount in the longitudinal direction of the shaft 3. This makes it possible, on the one hand, to compensate for inaccuracies and, on the other hand, the play between the rollers 8 and the running surfaces 15 of the profiled rail 14 can be set precisely. In order to secure the height adjustment of the holding tabs 5 and the roller carrier 7 against one another, the abutting surfaces of the parts are provided with transverse ribs in a manner not shown.

Die an der Welle 3 mittels der Schienen 10 längsverschiebbar gelagerte Tür 9 kann sowohl quer zur Welle 3 verschoben als auch mit dieser gedreht werden, so daß die Tür 9, wie in Fig. 2 gezeigt, hinter die Seitenwand des Korpus 2 geschoben werden kann. Durch den Eingriff der Zahnritzel 12 in die Zahnreihen 11 wird dabei gewährleistet, daß sich die Tür 9 bei der Öffnungs- bzw. Schließbewegung nicht verkanten kann. Vielmehr wird ein konstanter Gleichlauf der oberen und unteren Schiene erreicht.The door 9, which is mounted so as to be longitudinally displaceable on the shaft 3 by means of the rails 10, can be moved both transversely to the shaft 3 and also can be rotated with this so that the door 9, as shown in Fig. 2, can be pushed behind the side wall of the body 2. The engagement of the pinion 12 in the rows of teeth 11 ensures that the door 9 cannot tilt during the opening or closing movement. Rather, constant synchronization of the upper and lower rails is achieved.
