Description

Die Erfindung betrifft eine Laufrollenführungseinrichtung für eine Aufzugsschiebetür nach dem Oberbegriff des Anspruchs 1.The invention relates to a roller guide device for an elevator sliding door according to the generic term of Claim 1.

Laufrollenführungen für Schiebetüren ohne Laufdämpfung sind beispielsweise aus der US 3,460,189 und der US 4,642,844 bekannt. Die US 3,460,189 offenbart eine einfach herzustellende Rollenbaugruppe für ein Garagentor. Die Rollenbaugruppe ist als Blechkonstruktion ausgebildet und umfasst eine Steckachse sowie eine einstückig aus Metallblech geformte Laufrolle, die mit einem Wälzlager auf der Steckachse gelagert ist. Hinweise, die Laufrolle im Hinblick auf höhere Laufruhe zu gestalten sind nicht enthalten.Roller guides for sliding doors without barrel damping are for example from US 3,460,189 and US 4,642,844 known. US 3,460,189 discloses a simple one Roller assembly to be manufactured for a garage door. The Roller assembly is designed as a sheet metal structure and includes a thru axle and one piece Metal sheet-shaped roller with a roller bearing the thru axle is mounted. Notes, the roller in the To be designed with a view to smooth running are not contain.

Aus der US 2,611,920 ist eine Lauffrollenführung einer Aufzugsschiebetüre bekannt, bei der die Laufrolle schwingungsisoliert von den Aufzugstürbaugruppen gelagert ist. Ein schwingungsabsorbierender Einlagering ist fest in die Nabenbohrung der Laufrolle eingepresst und ist zusammen mit der massiven Laufrolle aus Metall auf den Aussenring eines Wälzlagers aufgesetzt. Ein längeres Verweilen in den Stillstandspositionen führt bei dieser Lauffrollenbauart zu unerwünschten Abplattungen des schwingungsdämpfenden Einlagerings. Diese Abplattungen erzeugen wiederum ein unrundes Abrollverhalten, welches vermehrten Verschleiss und grosse Laufunruhe beim Verschieben der Aufzugsschiebetür bedingt. From US 2,611,920 a roller guide is one Elevator sliding door known, in which the roller Vibration-insulated from the elevator door assemblies is. A vibration absorbing insert ring is firmly in the hub bore of the roller is pressed in and is together with the massive metal roller on the outer ring of a rolling bearing. A longer stay in the This castor type leads to standstill positions unwanted flattening of the vibration damping Insert rings. These flattenings in turn generate a non-circular rolling behavior, which increases wear and tear great uneven running when moving the elevator sliding door conditionally.

Mit der EP-PS 478 938 ist eine Laufrollenführung für eine Aufzugsschiebetür bekanntgeworden, bei der zur Verbesserung der Laufruhe die Laufrollen elastische Einlagen aufweisen. Die Einlagen bestehen aus nichtmetallischem, hartelastischem Material. Um Abplattungen der elastischen Einlagen zu vermeiden, werden die Laufflächen in den Stillstandspositionen entlastet. Dies geschieht durch seitlich der Führungsschiene angebrachte Rollenabhebeeinrichtungen. Diese sind als Rampenstücke, mit einer Rampe und einem Horizontalteil, ausgebildet. Die Randscheiben der Laufrollen ermöglichen ein Auffahren auf die Rampenstücke und ein Entlasten der Laufflächen.EP-PS 478 938 is a roller guide for one Elevator sliding door became known for improving For smooth running, the castors have elastic inserts. The inserts consist of non-metallic, hard elastic Material. To flatten the elastic inserts too avoid the treads in the Standstill positions relieved. This happens through attached to the side of the guide rail Roll lifting devices. These are as ramp pieces, with a ramp and a horizontal part. The Edge disks of the rollers enable opening the ramp sections and relieving the tread.

Im Fall einer abgenützten elastischen Einlage muss bei dieser Rollenbauart die gesamte Laufrolle ersetzt werden. Je weicher die Lauffläche beschaffen ist, um so besser wird die Laufruhe, aber desto grösser ist auch die Abnützung der Einlage. Durch die aufwendige Form der Laufrolle und das Anbringen der elastischen Einlage wird die Produktion zusätzlich verteuert. Ausserdem wird durch die Verwendung von weichen Laufflächeneinlagen das Einwalzen von Fremdkörpern ermöglicht, was die Laufruhe beeinträchtigt.In the case of a worn elastic insert, the this roller design, the entire roller can be replaced. Each the softer the tread is, the better it gets Smooth running, but the greater the wear of the Inlay. Due to the elaborate shape of the roller and that Production will attach the elastic insert additionally expensive. In addition, through the use rolling in soft tread inserts Allows foreign objects, which affects the smoothness.

Der Erfindung liegt die Aufgabe zugrunde, eine Laufrollenführung für eine Aufzugsschiebetür der eingangs genannten Art vorzuschlagen, welche deren Nachteile nicht aufweist und welche auf einfache Art eine hohe Laufruhe gewährleistet.The invention has for its object a Roller guide for an elevator sliding door at the entrance to propose the type mentioned, whose disadvantages do not and which is easy to run guaranteed.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass auch bei Dauerbelastung der Laufrollen der federnde Teil nur im elastischen Bereich des Werkstoffs beansprucht wird. Die Fertigung der Laufrollen wird stark vereinfacht und verbilligt, weil sie nur noch aus einem einzigen Werkstoff gefertigt sind. Zudem werden zur Erzielung der Federwirkung keine alterungsanfälligen Materialien verwendet.The advantages achieved by the invention are in essential to see that even with continuous load the rollers the resilient part only in the elastic range of the material is claimed. The manufacture of the Rollers is greatly simplified and cheaper because of them are only made from a single material. In addition are none to achieve the spring effect materials susceptible to aging are used.

Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Laufrollen möglich. Die harte Oberfläche der Laufflächen verhindert ein Einwalzen von Fremdkörpern, was eine hohe Laufruhe garantiert. Ausserdem wird mit harten Laufflächen der Abnützung entgegengewirkt, was eine lange Lebensdauer der Laufrollen gewährleistet.By the measures listed in the subclaims are advantageous developments and improvements in Claim 1 specified rollers possible. The hard one Surface of the treads prevents rolling in Foreign bodies, which guarantees smooth running. Furthermore is counteracted with hard treads of wear, which ensures a long service life of the rollers.
