Abstract

A runner guide for an elevator door has at the end points runner-lifting devices which, by means of ramp pieces (5, 6) and run-on edge discs (3, 4) of runners (1, 11), relieve the running surfaces of elastic running-surface inserts when at rest. In this way, flattenings in the elastic running surfaces and thus the rumbling noises resulting from this during the door movements are avoided. Taking into account the fact that the door travel (b) is greater than the runner spacing (a), a runner must be able to cross without contact a ramp piece (6) not intended for it. This is made possible through the use of an asymmetric runner (11) which has on one side an edge disc (12) of smaller diameter. The asymmetric runner (11) is only lifted when the opposite edge disc (4) of normal size runs onto a ramp piece (5). <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Führungsschiene und eine Laufrolle als Bestandteile einer automatischen Aufzugschiebetür, bei welcher die Laufrolle zwecks guter Laufruhe eine nichtmetallische und hartelastische Laufflächeneinlage und die Führungsschiene einen die Laufrolle führenden Querschnitt aufweist.The present invention relates to a guide rail and a roller as components of an automatic sliding door, in which the roller has a non-metallic and hard-elastic tread insert for smooth running and the guide rail has a cross section guiding the roller.

Es ist bekannt, dass Laufrollen mit metallenen Laufflächen auf metallenen Führungsschienen störende Laufgeräusche verursachen. Aus diesem Grunde wurden verschiedene Arten von nichtmetallenen Laufflächen für Laufrollen geschaffen, welche die Laufgeräusche vermindern helfen. Je weicher die Lauffläche beschaffen ist, um so kleiner wird das Laufgeräusch. Anderseits jedoch wächst der Rollwiderstand, der aber mit entsprechender Mehrantriebsleistung kompensiert werden kann. Wesentlich schlimmer wirkt sich das Phänomen der Laufflächenabplattung im Stillstand aus, weil infolgedessen ein holperiger Gang mit entsprechenden Rumpelgeräuschen die Folge ist. Die Abplattungen entstehen dadurch, dass eine belastete Rolle längere Zeit in der gleichen Position stehen bleibt. Dies trifft insbesondere bei automatischen Aufzugschiebetüren zu, da diese regelmässig mehrere Stunden in der Geschlossenstellung verharren müssen. Mit der amerikanischen Patentschrift US-2 611 920 wird eine gute Lösung beschrieben, welche die genannten Nachteile nicht aufweist und trotzdem eine gute Laufruhe verspricht. Die Laufrolle weist zwischen Kugellageraussenring und Rollenkörper eine vibrationsdämpfende Zwischenlage auf und die Rollenführungsschiene ebenfalls eine solche zwischen ihrem Fuss- und Oberteil. Eine Abplattung der Lauffläche kann nicht stattfinden, wobei aber die zu erzielende Laufruhe ein erwünschtes Mass eventuell noch nicht erreicht. Trotz den vibrationsdämpfenden Zwischenlagen in der Rolle und in der Führungsschiene findet immer noch eine Metall auf Metall-Rollreibung statt. Zudem ist die Konstruktion sehr aufwendig, womit auch die Kosten ein für diese Anwendung vertretbares Mass übersteigen dürften.It is known that castors with metal treads on metal guide rails cause disturbing running noises. For this reason, various types of non-metal treads for rollers have been created which help to reduce the running noise. The softer the tread is, the smaller the running noise. On the other hand, however, the rolling resistance is growing, but this can be compensated for with the corresponding additional drive power. The phenomenon of tread flattening at a standstill has a much worse effect because the result is a bumpy walk with the corresponding rumble noise. The flattening results from the fact that a loaded roll remains in the same position for a long time. This is particularly the case with automatic elevator sliding doors, since they must regularly remain in the closed position for several hours. The American patent specification US-2 611 920 describes a good solution which does not have the disadvantages mentioned and nevertheless promises smooth running. The roller has a vibration-damping intermediate layer between the ball bearing outer ring and the roller body, and the roller guide rail also has one between its foot and upper part. The tread cannot be flattened, but the smoothness to be achieved may not yet reach a desired level. Despite the vibration-damping intermediate layers in the roll and in the guide rail, there is still metal on metal rolling friction. In addition, the construction is very complex, with which the costs should exceed a reasonable level for this application.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine Rollenführung mit Rolle zu schaffen, welche die genannten Nachteile nicht aufweist, welche einfach und billig herzustellen ist, und mit welcher bestehende, automatische Aufzugschiebetüren ausgerüstet werden können.The present invention has for its object to provide a roller guide with roller, which does not have the disadvantages mentioned, which is easy and inexpensive to manufacture, and with which existing automatic elevator sliding doors can be equipped.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete Erfindeung gelöst.This object is achieved by the invention characterized in the claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Lösung einerseits durch eine angepasste Formgebung eines Standardmaschinenteils und durch wenige zusätzliche einfachste Maschinenbauelemente erzielt wird, und dass anderseits die Laufkultur der Rollenführung an einer Aufzugstür bisher nicht bekannte Werte erreicht. Die Lösung vereinigt alle Vorteile einer elastischen Rollenlauffläche ohne aber die Nachteile einer Laufflächenabplattung bei längerem Stillstand unter Last.The advantages achieved by the invention are essentially to be seen in the fact that the solution is achieved on the one hand by adapting the shape of a standard machine part and by a few additional simple machine components, and on the other hand the running culture of the roller guide on an elevator door achieves values not previously known. The solution combines all the advantages of an elastic roller tread without the disadvantages of tread flattening during long periods of non-use under load.

In der Zeichnungnen sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt, und es zeigen

  • Fig.1 eine Laufrolle auf Führungsschiene in Zwischenstellung und im Querschnitt,
  • Fig.2 eine Laufrolle auf Führungsschiene in Endstellung und im Querschnitt,
  • Fig.3 eine Laufrolle auf Führungsschiene in Endstellung und als Seitenansicht,
  • Fig.4 eine unsymmetrische Laufrolle auf Führungsschiene und im Querschnitt und
  • Fig.5 eine vordere Teilansicht einer Aufzugschiebetür.
In the drawings, two exemplary embodiments of the subject matter of the invention are shown and show
  • 1 a roller on the guide rail in the intermediate position and in cross section,
  • 2 shows a roller on the guide rail in the end position and in cross section,
  • 3 a roller on the guide rail in the end position and as a side view,
  • 4 shows an asymmetrical roller on the guide rail and in cross section and
  • 5 shows a partial front view of an elevator sliding door.

In der Fig.1 ist mit 1 der Rollenkörper bezeichnet, welcher eine elastische Einlage 2 mit einer halbrunden Lauffläche 10 und zwei starre, vorzugsweise aus Metall bestehende, beidseitig der Lauffläche 10 vorstehende Randscheiben 3 und 4 aufweist.In FIG. 1, 1 denotes the roller body, which has an elastic insert 2 with a semicircular tread 10 and two rigid, preferably made of metal, edge plates 3 and 4 protruding on both sides of the tread 10.

Die Randscheiben 4 und 5 sind aus gleichem Material wie der Rollenkörper und kompakter Bestandteil desselben. Die Lauffläche 10 läuft auf einem halbrunden Kopfteil 7.1 einer Führungsschiene 7. Die Führungsschiene 7 besitzt einen verbreiterten Basisteil 7.3 und einen prismatischen Vertikalschenkel 7.2, der mit dem halbrunden Kopfteil 7.1 abschliesst.The edge discs 4 and 5 are made of the same material as the roller body and are a compact part of the same. The tread 10 runs on a semicircular head part 7.1 of a guide rail 7. The guide rail 7 has a widened base part 7.3 and a prismatic vertical leg 7.2, which ends with the semicircular head part 7.1.

In der Fig.2 sind die gleichen Teile dargestellt plus je auf den Seitenflanken des prismatischen Vertikalschenkels 7.2 angebrachte Rampenstücke 5 und 6. Deren Höhe ist so bemessen, dass die starren Randscheiben 3 und 4 auf den Oberseiten auflaufen und die elastische Lauffläche 10 völlig entlasten.2 shows the same parts plus ramp pieces 5 and 6 each attached to the side flanks of the prismatic vertical leg 7.2. Their height is dimensioned such that the rigid edge disks 3 and 4 run up on the upper sides and completely relieve the elastic tread 10.

In der Fig.3 ist die gleiche Situation als Seitenansicht dargestellt. Die Randscheibe 4 ist von links nach rechts via eine Rampe 8 auf einen horizontalen Teil 9 des Rampenstückes 6 aufgelaufen und hat, infolge der Abmessungen von Randscheibendurchmesser und Rampenstückhöhe, die Lauffläche 10 der Rolle 1 durch Abheben entlastet. Die Rampe 8 hat beispielsweise ein Steigungsverhältnis von s zu x gleich zehn zu eins.3 shows the same situation as a side view. The edge disk 4 has run up from left to right via a ramp 8 onto a horizontal part 9 of the ramp piece 6 and, due to the dimensions of the rim disk diameter and ramp piece height, has relieved the tread 10 of the roller 1 by lifting it off. The ramp 8 has, for example, a gradient ratio of s to x equal to ten to one.

In der Fig.4 ist im Querschnitt eine unsymmetrische Rolle 11 dargestellt, welche rechts eine starre Randscheibe 12 mit einem gegenüber der linken starren Randscheibe 4 kleineren Durchmesser aufweist. Die unsymmetrische Rolle 11 kann ein auf der rechten Seite der Führungsschiene 7 angebrachtes Rampenstück 6 überfahren, ohne dass dabei ihre Lauffläche 10 abgehoben, also entlastet wird. Durch diese Massnahme ist es möglich, das Prinzip für Schiebetürflügel anzuwenden, bei welchen der Rollenabstand kleiner ist als der Verschiebeweg.An asymmetrical roller 11 is shown in cross section in FIG. 4, which on the right has a rigid peripheral disk 12 with a smaller diameter than the left rigid peripheral disk 4. The asymmetrical roller 11 can run over a ramp piece 6 attached on the right side of the guide rail 7 without its running surface 10 being lifted off, that is to say relieved. This measure makes it possible to apply the principle for sliding door leaves in which the roller spacing is smaller than the displacement path.

In der Fig.5 ist in einer vorderen Teilansicht einer automatischen Aufzugschiebetür das Prinzip in einer praktischen Anwendung ersichtlich. Ein linker Türflügel 14 ist mit je einer Aufhängung 13 mit einer Rolle 1 und einer unsymmetrischen Rolle 11 verbunden und ein rechter, nicht mehr voll dargestellter Türflügel 15 auf gleiche Art mit zwei Rollen 1 und 11. Die rechte unsymmetrische Rolle 11 des Türflügels 14 ist so eingebaut, dass sich ihre kleinere Randscheibe 12 vorn befindet. Dementsprechend sind auch die den Rollen 1 und 11 zugeordneten Rampenstücke 5 und 6 einmal vorn und einmal hinten an der Führungsschiene 7 angebracht.5 shows the principle in a practical application in a partial front view of an automatic elevator sliding door. A left door leaf 14 is each connected to a suspension 13 with a roller 1 and an asymmetrical roller 11 and a right, not fully shown door leaf 15 in the same way with two rollers 1 and 11. Die Right asymmetrical roller 11 of the door leaf 14 is installed so that its smaller edge plate 12 is at the front. Accordingly, the ramp pieces 5 and 6 assigned to the rollers 1 and 11 are attached to the guide rail 7 once at the front and once at the rear.

Die vorstehend in den Figuren beschriebene Einrichtung arbeitet wie folgt:
In der Fig.5 ist weiter dargestellt, dass ein Rollenabstand a kleiner ist als ein Verschiebeweg b. Dass bedeutet, dass bei einer Oeffnungsbewegung die unsymmetrische Rolle 11 das linke vorn angebrachte Rampenstück 5 ohne Berührung überfahren können muss. Das ist infolge der vorn kleineren Randscheibe 12 der rechten unsymmetrischen Rolle 11 möglich. In der dargestellten Anwendung ist eine Entlastung der Laufflächen 10 der Rollen 1 und 11 nur in der Geschlossenstellung der Aufzugschiebetür vorgesehen. Dies deshalb, weil bei einem Aufzug üblicherweise die Verweilzeit der Aufzugstür in der Geschlossenstellung viel länger ist als jene in der Offenstellung. Es ist aber bei Bedarf ohne weiteres möglich, eine Entlastung der Laufflächen 10 in beiden Endstellungen der Tür vorzusehen. Dabei werden alles nur unsymmetrische Rollen 11 eingesetzt und auf der vorderen und auf der hinteren Seite der Führungsschiene je zwei Rampenstücke 5 und 6 angebracht. Das Auflaufen der Randscheiben auf die Rampenstücke ist nicht als Geräusch hörbar, weil die Türgeschwindigkeit im Bereich der Endstellungen sehr klein ist.The device described above in the figures works as follows:
5 further shows that a roller distance a is smaller than a displacement path b. This means that during an opening movement, the asymmetrical roller 11 must be able to drive over the left front ramp piece 5 without touching it. This is possible due to the smaller front disc 12 of the right asymmetrical roller 11. In the application shown, relief of the running surfaces 10 of the rollers 1 and 11 is only provided in the closed position of the elevator sliding door. This is because, in the case of an elevator, the residence time of the elevator door in the closed position is usually much longer than that in the open position. If necessary, however, it is easily possible to provide relief of the running surfaces 10 in both end positions of the door. Here, only asymmetrical rollers 11 are used and two ramp pieces 5 and 6 are attached to the front and rear side of the guide rail. The impact of the edge discs on the ramp sections is not audible as noise, because the door speed is very low in the area of the end positions.

Es können relativ weiche Dämpfungseinlagen 2 vorgesehen werden, weil die Rollen in den Endstellungen nicht mehr auf den Laufflächen stehen bleiben und so keine Abplattungen entstehen können. Die Bewegung einer Aufzugschiebetür wird mit dieser Einrichtung praktisch geräuschlos. Die Einrichtung lässt sich auch bei anderen Arten von Schiebetüren anwenden wie beispielsweise bei Eingangstüren in Geschäften und Hotels oder bei irgendwelchen hausinternen Verbindungstüren in Bürohäusern, Wohnhäusern oder Spitälern. Ebenfalls kann die Einrichtung bei Teleskoptüren angewendet werden, wo der Laufruheeffekt insbesondere beim schnellaufenden Türflügel zum Tragen kommt.Relatively soft damping inserts 2 can be provided because the rollers no longer remain on the treads in the end positions and flattening cannot occur. The movement of an elevator sliding door is practically noiseless with this device. The device can also be used for other types of sliding doors, such as entrance doors in shops and hotels or for any internal connecting doors in office buildings, apartment buildings or hospitals. The device can also be used for telescopic doors, where the smooth running effect comes into play, particularly with the high-speed door leaf.
