The vertical position between the sliding door (5) and the top of the cabinet can be adjusted by changing the distance between the mounting housing (13) and the running gear holder (15) as the control gear (29) is rotated.

Description

Laufwerk für eine SchiebetürDrive for a sliding door
Gegenstand der Erfindung ist ein Laufwerk für eine Schiebetür gemäss den Oberbegriffen der Patentansprüche 1 und 3.The invention relates to a drive for a sliding door according to the preambles of claims 1 and 3.
Schiebetüren an Schränken im Haushalt und im Büro werden heute, wenn hohe Anforderungen an hohe Laufruhe und leichte Verschiebbarkeit gestellt werden, mittels Rollen gelagert. Leichtere Schiebetüren werden meistens hängend an Laufwerken aufgehängt, welche in Schienen geführt sind, die auf oder in die Schrankdecke eingelassen worden sind. Um die Laufwerke für den Betrachter des Schranks unsichtbar zu machen, sind diese sehr klein ausgebildet und werden an der Rückseite bzw. in einer Topfbohrung an der Rückseite der Schiebetür befestigt. Die bekannten Laufwerke umfassen meist einen Sockel, der in die Topfbohrung an der Schiebetür eingesetzt wird und in den das Gehäuse des Laufwerks nach der Montage der Tür einschiebbar ist . Das Laufwerk selbst und dessen Gehäuse werden üblicherweise zusammen mit der Führungsschiene an der Decke des Schranks befestigt, bevor die Tür mit den Laufwerk verbunden wird. Um Massungenauigkeiten ausgleichen zu können, ist es bekannt, den Laufwerkträger mit den daran befestigten Laufrollen durch eine Spindel mit dem Gehäuse zu verbinden. Durch Drehen an einem auf der Spindel kämmenden Stellrad kann der Abstand zwischen dem Laufwerk und dem Gehäuse und damit der Schiebetür zur Decke des Schranks nach deren Einbau justiert werden. Dabei wird die das Gehäuse und den Rollenträger verbindende Gewindestange vom Stellrad, welches auf dem Gewinde kämmt, vertikal verschoben.Sliding doors on cabinets in the home and office are today, when high demands are placed on high smoothness and ease of displacement, stored by means of rollers. Lighter sliding doors are usually hung suspended on drives which are guided in rails, which have been let in or on the cabinet ceiling. To make the drives invisible to the viewer of the cabinet, they are very small and are attached to the back or in a pot bore on the back of the sliding door. The known drives usually comprise a base which is inserted into the pot bore on the sliding door and in which the housing of the drive after assembly of the door can be inserted. The drive itself and its housing are usually fastened together with the guide rail to the ceiling of the cabinet before the door is connected to the drive. To compensate for inaccuracies, it is known the drive carrier to connect with the attached rollers by a spindle with the housing. By turning a wheel meshing with the spindle, the distance between the drive and the housing and thus the sliding door to the ceiling of the cabinet can be adjusted after installation. The threaded rod connecting the housing and the roller carrier is displaced vertically by the adjusting wheel, which meshes with the thread.
Eine Aufgabe der vorliegenden Erfindung besteht nun darin, ein Laufwerk für Schiebetüren zu schaffen, das äusserst kostengünstig herstellbar ist und aus möglichst wenigen Einzelteilen besteht.An object of the present invention is to provide a drive for sliding doors, which is extremely inexpensive to produce and consists of as few individual parts.
Eine weitere Aufgabe der Erfindung besteht darin, das Laufwerk derart auszubilden, dass die Abrollgeräusche der Rollen am Laufwerkträger so weit wie möglich gedämpft werden. Eine weitere Aufgabe besteht darin, dass die Reibung zwischen den Laufrollen und dem Laufwerkträger so klein wie möglich gehalten wird, um das Verschieben der Schiebetüren möglichst komfortabel zu gestalten.Another object of the invention is to form the drive so that the rolling noise of the rollers are damped as much as possible on the drive carrier. Another object is that the friction between the rollers and the drive carrier is kept as small as possible in order to make the sliding of the sliding doors as comfortable as possible.
Gelöst werden diese Aufgaben durch ein Laufwerk gemäss den Merkmalen der Patentansprüche 1 und 3. Vorteilhafte Ausgestaltungen der Laufwerke sind in den anhängigen Ansprüchen umschrieben. In vorteilhafter Weise wird das Gehäuse direkt mit der Spindel, an welcher die Stellschraube fest angeordnet ist, in der Höhe eingestellt. Das Gehäuse kann direkt in den Sockel eingeschoben werden. Durch eine elastische Lagerung in einer Gewindebüchse, die im Laufwerkträger eingesetzt ist, können Abrollgeräusche, verursacht durch ungenauen Rundlauf der Laufrollen von der Schiebetür fern gehalten und damit deren Ausbreitung auf den Schrank vermindert werden. Alternativ oder zusätzlich können die Wellen, an denen die Laufrollen befestigt sind, elastisch gedämpft am Laufwerkträger gelagert sein. Durch feine Schlitze in den Bonrungen für die die Laufrollen tragenden Wellen am Laufwerkträger kann ein Schmiermittel zugeführt werden und so die Reibung \m.& der Verschleiss bischer, &er± lia-αfrollerL und dem Laufwerkträger vermindert werden.These objects are achieved by a drive according to the features of claims 1 and 3. Advantageous embodiments of the drives are described in the appended claims. Advantageously, the housing is adjusted in height directly with the spindle on which the adjusting screw is fixed. The housing can be inserted directly into the socket. By an elastic bearing in a threaded bushing, which is used in the drive carrier, rolling noise, caused by inaccurate concentricity of the rollers kept away from the sliding door and thus their spread to the cabinet can be reduced. Alternatively or additionally, the waves on which the rollers are mounted, elastically damped be stored on the drive carrier. Fine lubrication in the ledges for the shafts supporting the rollers on the drive carrier can be applied to lubricate the friction and reduce the wear of the wearer, oil pan, and drive carrier.

Zur Veranschaulichung der Anordnung eines Laufwerks 1 in einem Schrank 3 sind in Figur 8 eine Schiebetür 5 mit einem in eine Topfbohrung eingesetzten Sockel 7, eine in der Schrankdecke 9 eingelassene Führungsschiene 11 und ein Befestigungsgehäuse 13 mit darüber angeordnetem Laufrollenträger 15 dargestellt. Das Befestigungsgehäuse 13 ist noch nicht in den Sockel 7 eingeschoben und die Rollen 17 am Laufwerkträger 15 sind noch nicht in die Führungsschiene 11 eingeführt.To illustrate the arrangement of a drive 1 in a cabinet 3, a sliding door 5 with a base 7 inserted into a cup hole, a recessed in the cabinet ceiling 9 guide rail 11 and a mounting housing 13 with arranged above roller bearing support 15 are shown in Figure 8. The mounting housing 13 is not yet inserted into the base 7 and the rollers 17 on the drive carrier 15 are not in the Guide rail 11 introduced.
In der ersten Ausgestaltung der Erfindung gemäss Figur 1 ist auf der linken Figurenseite der Sockel 7 von hinten dargestellt. Der rückseitige zylindrische Abschnitt 19 dient dazu, mit geringstem Spiel in die Topfbohrung an der Schiebetür 5 eingeschoben zu werden. Mit nicht dargestellten Schrauben, welche durch Bohrungen 21 hindurchgeführt werden, wird der Sockel 7 an der Schiebetür 5 befestigt. Das rechts vom Sockel 7 dargestellte Gehäuse 13, welches in den Sockel 7 einschiebbar ist, wird im Sockel 7 von Schnappelementen 23 gehalten. Im Gehäuse 13 ist eine halbzylindrische Bohrung 25 ausgebildet, in welcher eine zylindrische Spindel 27 mit einem fest daran angeformten Bestätigungsrad 29 geführt wird. Das Betätigungsrad 29 weist vorzugsweise an dessen Peripherie eine Randrierung oder die Gestalt eines Zahnrades auf. Im Gehäuse 13 sind weiter eine obere Anschlagfläche 31 und eine untere Anschlagfläche 33 ausgebildet, zwischen denen die oberen und unteren Stirnflächen des Betätigungsrades 29 mit geringem Spiel zu liegen kommen. Damit das Betätigungsrad 29 mit der daran fest angeformten Spindel 27 im Gehäuse 13 gehalten werden kann, ist im ersten Ausführungsbeispiel (Figur 1) ein Deckel 35 vorgesehen, der ebenfalls eine halbzylindrische Bohrung 37 aufweist und zudem ein Fenster 39, durch welches die Peripherie des Betätigungsrads 29 hinausragt, wenn der Deckel 35 am Gehäuse 13 aufgesetzt und zuvor die Spindel 27 in die Halbschalen eingesetzt sind. Am Gehäuse 13 sind seitlich Rastelemente 41 angeformt, welche mit geeigneten Rastmitteln 43 am Deckel 35 zusammenwirken, wenn letzterer in das Gehäuse 13 eingeschoben ist. Bei eingeschobenem Deckel 35 bilden die an den beiden Elementen ausgebildeten halbzylindrischen Bohrungen 25 und 37 eine zylindrische Bohrung als Lager für die zylindrische Spindel 27. Das Betätigungsrad 29 liegt dann mit geringem Spiel zwischen den beiden Anschlagflächen 31 und 33.In the first embodiment of the invention according to Figure 1, the base 7 is shown from the rear on the left side of the figure. The rear cylindrical portion 19 serves to be inserted with minimal play in the pot bore on the sliding door 5. With screws, not shown, which are passed through holes 21, the base 7 is attached to the sliding door 5. The right side of the base 7 shown housing 13, which is inserted into the base 7, is held in the base 7 of snap elements 23. In the housing 13, a semi-cylindrical bore 25 is formed, in which a cylindrical spindle 27 is guided with a firmly attached thereto confirmation wheel 29. The actuating wheel 29 preferably has on the periphery of a Randrierung or the shape of a gear on. In the housing 13, an upper stop surface 31 and a lower stop surface 33 are further formed between which the upper and lower end faces of the actuating wheel 29 come to lie with little play. Thus, the operating wheel 29 can be held in the housing 13 with the spindle 27 firmly formed thereon, in the first embodiment (Figure 1), a lid 35 is provided which also has a semi-cylindrical bore 37 and also a window 39 through which the periphery of the actuating wheel 29 protrudes, when the lid 35 is placed on the housing 13 and previously the spindle 27 are inserted into the half-shells. On the housing 13 locking elements 41 are formed laterally, which cooperate with suitable locking means 43 on the cover 35 when the latter is inserted into the housing 13. When the cover 35 is inserted, the semi-cylindrical bores 25 and 37 formed on the two elements form a cylindrical bore as a bearing for the cylindrical spindle 27. The actuating wheel 29 then lies with slight play between the two stop surfaces 31 and 33.
Das obere Ende 45 der zylindrischen Spindel 27 kämmt in einer Gewindebohrung 47 im Laufwerkträger 15. Weiter sind im Laufwerkträger 15 zwei Achslagerbohrungen 49 für die Wellen 51 der Rollen 17 eingelassen.The upper end 45 of the cylindrical spindle 27 meshes in a threaded bore 47 in the drive carrier 15. Further, in the drive carrier 15, two axle bearing bores 49 for the shafts 51 of the rollers 17 are inserted.
In der zweiten Ausführungsform des Laufwerks gemäss Figur 2 sind mit den gleiche Bezugszeichen die entsprechenden Elemente bezeichnet. Im Unterschied zur ersten Ausgestaltung der Erfindung tritt anstelle eines Deckels 35, mit welchem die zylindrische Spindel 27 im Gehäuse 13 gehalten wird, eine Schnappvorrichtung am Gehäuse 13, welche durch zwei elastische Laschen 53 gebildet wird. Die Stirnflächen der Laschen 53 , welche der halbzylindrischen Bohrung 25 gegenüberliegen, bilden mit der halbzylindrischen Bohrung 25 das Lager für die Spindel 27. Durch diese Massnahme kann auf einen Deckel verzichtet werden. Im dritten Ausführungsbeispiel gemäss den Figuren 3 bis 6 sind wiederum die gleichen Bezugszeichen verwendet worden wie in den beiden erstgenannten gemäss den Figuren 1 und 2. Das Gehäuse 13 entspricht demjenigen in Figur 1. Es wird durch einen Deckel 35 gemäss Figur 1 verschlossen. Alternativ ist es selbstverständlich auch möglich, das Gehäuse 13 gemäss Figur 2 (zweites Ausführungsbeispiel) auszubilden und dadurch auf einen Deckel 35 zu verzichten. Im Laufwerkträger 15 ist keine Gewindebohrung eingelassen, sondern ein Dämpfungselement 55. Dieses umfasst innen eine Gewindehülse 57, welche im Innern das Gewinde 47 trägt und aussen ein Dämpfungsring 59, in dessen Bohrung die Gewindehülse eingesetzt ist. Der Dämpfungsring 59 aus einem elastischen Material weist beispielsweise nach innen ragende Rippen oder Stege 61 auf, welche Vibrationen dämpfen. Das Dämpfungselement 55 ist spielfrei in einer Ausnehmung 63 am Laufwerkträger 15 eingesetzt.In the second embodiment of the drive according to FIG. 2, the same reference numerals designate the corresponding elements. In contrast to the first embodiment of the invention occurs instead of a lid 35, with which the cylindrical spindle 27 is held in the housing 13, a snap device on the housing 13, which is formed by two elastic tabs 53. The end surfaces of the tabs 53, which are opposite to the semi-cylindrical bore 25, form with the semi-cylindrical bore 25, the bearing for the spindle 27. By this measure can be dispensed with a cover. In the third embodiment according to FIGS. 3 to 6, the same reference numerals have again been used as in the first two according to FIGS. 1 and 2. The housing 13 corresponds to that in FIG. 1. It is closed by a cover 35 according to FIG. Alternatively, it is of course also possible to form the housing 13 according to FIG. 2 (second exemplary embodiment) and thereby dispense with a cover 35. In the drive carrier 15 no threaded hole is inserted, but a damping element 55. This includes inside a threaded sleeve 57 which carries the thread 47 inside and outside a damping ring 59, in the bore of the threaded sleeve is inserted. The damping ring 59 made of an elastic material has, for example, inwardly projecting ribs or webs 61, which damp vibrations. The damping element 55 is inserted without play in a recess 63 on the drive carrier 15.
Alternativ zu einer zylindrischen Achslagerbohrung mit glatten Laufflächen können in der Bohrungswandung Rillen 65 eingelassen sein, die vor dem Einschieben der Wellen 51 der Rollen 17 mit einem Schmiermittel aufgefüllt werden (Figur 7) .As an alternative to a cylindrical axle bearing bore with smooth running surfaces grooves 65 can be embedded in the bore wall, which are filled with a lubricant before insertion of the shafts 51 of the rollers 17 (FIG. 7).
In einer weiteren möglichen Ausführungsform können die Wellen 51 an den Rollen 17 in Büchsen 67 geführt sein. Die Büchsen 67 umfassen eine Aussenbüchse 69 und eine Innenbüchse 71. Die Aussenbüchse 69 ist vorzugsweise aus einem elastischen Material und die Innenbüchse 71 aus einem Metall oder Kunststoff gefertigt, welcher geeignet ist, die Wellen 51 reibungsarm aufzunehmen. Selbstverständlich können in der Innenbüchse 71 analog zum Ausführungsbeispiel nach Figur 7 Rillen 65 zum Einbringen eines Schmiermittels vorgesehen sein. Durch die elastisch ausgebildete Aussenbüchse 69 werde Vibrationen an den Rollen 17 nicht auf den Laufwerkträger 15 übertragen oder zumindest gedämpft übertragen.In a further possible embodiment, the shafts 51 may be guided on the rollers 17 in bushings 67. The Bushings 67 comprise an outer bushing 69 and an inner bushing 71. The outer bushing 69 is preferably made of an elastic material and the inner bushing 71 is made of a metal or plastic, which is adapted to receive the shafts 51 with low friction. Of course, in the inner sleeve 71 analogous to the embodiment of Figure 7 grooves 65 may be provided for introducing a lubricant.
