Description

Die Erfindung betrifft eine Laufrollenführung einer Aufzugsschiebetür mit Führungsschiene und darauf abrollenden Laufrollen, welche zwecks Laufruhe und Geräuschverminderung dämpfende und federnde Elemente aufweist.The invention relates to a roller guide of an elevator sliding door with a guide rail and rollers rolling thereon, which has damping and resilient elements for the purpose of smoothness and noise reduction.

Mit der EP-PS 478 938 ist eine Laufrollenführung für eine Aufzugsschiebetür bekanntgeworden, bei welcher die Laufrollen nichtmetallische, hartelastische Laufflächeneinlagen aufweisen, um gute Laufruhe zu gewährleisten und die Laufgeräusche zu vermindern. Eine Rollenanhebeeinrichtung entlastet die Laufflächen der Laufrollen in den Stillstandspositionen, um Abplattungen der elastischen Laufflächeneinlagen zu verhindern und die daraus folgenden Rumpelgeräusche bei den Türbewegungen zu vermeiden. Diese Anhebeeinrichtung ist als Rampenstück ausgebildet, welches eine Rampe und einen Horizontalteil aufweist und seitlich der Führungsschiene angebracht ist. Die Randscheiben der Laufrolle ermöglichen ein Auffahren auf das Rampenstück und ein Entlasten der Lauffläche.EP-PS 478 938 discloses a roller guide for an elevator sliding door, in which the rollers have non-metallic, hard-elastic tread inserts in order to ensure smooth running and to reduce running noise. A roller lifting device relieves the running surfaces of the running rollers in the standstill positions in order to prevent flattening of the elastic running surface inserts and to avoid the resulting rumbling noises during door movements. This lifting device is designed as a ramp piece which has a ramp and a horizontal part and is attached to the side of the guide rail. The edge disks of the roller enable the ramp section to be opened and the tread to be relieved.

Bei der vorstehend beschriebenen Laufrollenführung werden mittels einer aufwendigen Konstruktion die Laufflächen entlastet, um Abplattungen zu verhindern. Im Fall einer abgenützten Laufflächeneinlage muss die gesamte Laufrolle ersetzt werden. Die Verwendung von harten Materialien für die Führungsschiene ermöglicht zudem eine weitere Schallausbreitung in derselben. Ausserdem ist ein Einwalzen von Fremdkörpern in die weiche Laufflächeneinlage der Laufrollen möglich, was die Laufruhe beeinträchtigt und die Geräuschentwicklung erhöht.In the case of the roller guide described above, the treads are relieved by means of a complex construction in order to prevent flattening. In the event of a worn tread insert, the entire roller must be replaced. The use of hard materials for the guide rail also allows further sound propagation in the same. In addition, foreign bodies can be rolled into the soft tread insert of the rollers, which affects smoothness and increases noise.

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 to propose a roller guide for an elevator sliding door of the type mentioned, which does not have its disadvantages and which ensures a high level of smoothness in a simple manner.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in claim 1.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass auch im Dauerbetrieb die von der Tür ausgehende Geräuschentwicklung wirkungsvoll und wartungsfrei gemindert wird. Der federnde Teil der Laufrollenführung wird auch bei Dauerbelastung nur im elastischen Bereich des Werkstoffs beansprucht. Die Fertigung der Laufrollen wird stark vereinfacht und verbilligt. Die Führungsschienen sind als Bandmaterial kostengünstig zu fertigen. Durch die Verwendung von elastischen Einlagen in der Führungsschiene wird eine Schallausbreitung unterdrückt.The advantages achieved by the invention are essentially to be seen in the fact that the noise generated by the door is effectively and maintenance-free reduced even in continuous operation. The resilient part of the roller guide is only stressed in the elastic range of the material even under permanent load. The manufacture of the rollers is greatly simplified and cheaper. The guide rails are inexpensive to manufacture as strip material. Sound propagation is suppressed by the use of elastic inserts in the guide rail.

Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Laufrollenführung möglich. Da die Laufflächen der Führungsschiene und der Laufrollen aus harten Materialien bestehen, ist ein Einwalzen von Fremdkörpern nicht mehr möglich, was eine Erhöhung der Laufruhe und damit eine weitere Geräuschverminderung darstellt. Durch die grosse Oberfläche des elastischen Teils der Laufrollenführung wird der Abnützung entgegengewirkt, was eine lange Lebensdauer der Führungsschiene garantiert.The measures listed in the subclaims allow advantageous developments and improvements of the roller guide specified in claim 1. Since the running surfaces of the guide rail and the rollers are made of hard materials, it is no longer possible to roll in foreign objects, which increases the smoothness and thus further reduces noise. The large surface of the elastic part of the roller guide counteracts wear, which guarantees a long service life for the guide rail.

Fig.1 zeigt eine Ansicht einer Aufzugsschiebetür. Laufrollen 1 rollen mit ihren Laufflächen 2 über eine Schienenlauffläche 3 ab. Die Schienenlauffläche 3 weist eine gewölbte, insbesondere konkave oder konvexe Form auf um eine optimale Führung der Laufrollen 1 zu gewährleisten und ist Bestandteil einer Führungsschiene 11. Türflügel 56 mit Aufhängungen 57 sind über Achsen 58 und daran angebrachten Wälzlagern 59 mit den Laufrollen 1 verbunden. Durch eine Schraube 12 an der Führungsschiene 11 kann die Elastizität der Füllung 5 je nach Türgewicht und Geschwindigkeit eingestellt werden.1 shows a view of an elevator sliding door. Rollers 1 roll with their running surfaces 2 over a rail running surface 3. The rail running surface 3 has a curved, in particular concave or convex shape to ensure optimal guidance of the rollers 1 and is part of a guide rail 11. Door wings 56 with suspensions 57 are connected to the rollers 1 via axes 58 and roller bearings 59 attached to them. With a screw 12 on the guide rail 11, the elasticity of the filling 5 can be adjusted depending on the door weight and speed.

In Fig.2a ist mit 1 eine Laufrolle bezeichnet, welche vorzugsweise gänzlich aus keramischem Material oder auch aus Metall besteht und deren Lauffläche 2 über eine Schienenlauffläche 3 abrollt. Ein schlauchartiger Mantel 4 aus Stahlblech, dessen Schienenlauffläche 3 konvex gewölbt ist, wird so dimensioniert, dass die Federwirkung nur im elastischen Bereich des Bleches beansprucht wird. Um eine optimale Federwirkung zu erzielen, ist der Radius der Lauffläche 2 der Laufrolle 1 etwas grösser als der Radius der Schienenlauffläche 3. Innerhalb des schlauchartigen Mantels 4 ist eine elastische Füllung 5, z.B. Gummi, angebracht, welche das durch Bewegung der Laufrolle 1 erzeugte Laufgeräusch dämpft und eine Schallausbreitung in der Führungsschiene 11 verhindert. Durch ein Tragprofil 6, das aus einem Unterteil 7 und einem Oberteil 8 besteht, und einer Verschraubung 9 wird der schlauchartige Mantel 4 fixiert. Eine Aussparung 10 zwischen Unterteil 7 und Oberteil 8 im Tragprofil 6 bietet Platz für den schlauchartigen Mantel 4, wobei die Klemmwirkung durch mehrere, über die gesamte Länge der Führungsschiene 11 verteilte Verschraubungen 9 erzielt wird. Eine andere Möglichkeit ist, den schlauchartigen Mantel 4 direkt an das Tragprofil 6 anzuschweissen oder anzukleben.In Figure 2a, 1 denotes a roller, which preferably consists entirely of ceramic material or metal, and whose tread 2 rolls over a rail tread 3. A tubular jacket 4 made of sheet steel, the rail running surface 3 of which is convex, is dimensioned such that the spring action is only stressed in the elastic area of the sheet. In order to achieve an optimal spring action, the radius of the running surface 2 of the roller 1 is somewhat larger than the radius of the rail running surface 3. Inside the tubular jacket 4, an elastic filling 5, for example rubber, is attached, which produces the running noise generated by the movement of the roller 1 dampens and prevents sound propagation in the guide rail 11. The tubular jacket 4 is fixed by a support profile 6, which consists of a lower part 7 and an upper part 8, and a screw connection 9. A cutout 10 between the lower part 7 and the upper part 8 in the support profile 6 offers space for the tubular jacket 4, the clamping effect being achieved by a plurality of screw connections 9 distributed over the entire length of the guide rail 11. Another possibility is to weld or glue the tubular jacket 4 directly to the support profile 6.

Fig.2b zeigt eine Ausführung für erhöhte Ansprüche nach Fig.2a. Innerhalb des schlauchartigen Mantels 4 wird anstelle der elastischen Füllung 5 über die gesamte Länge der Führungsschiene 16 ein elastisches Kissen 17, z.B. aus Gummi, eingelegt. Durch ein Tragprofil 18, das aus einem Unterteil 19, einem Oberteil 20 und einem beweglichen Stempel 21 besteht, und einem Gewinde 22 wird der schlauchartige Mantel 4 wie in Fig.2a fixiert. Hier besteht ebenfalls die Möglichkeit, den schlauchartigen Mantel 4 an das Tragprofil 18 anzuschweissen. Durch den beweglichen Stempel 21 und das Gewinde 22 kann der Druck auf das elastische Kissen 17 verändert werden, was einer Reduktion oder einer Erhöhung des Federweges entspricht. Durch die Verteilung der Gewinde 22 über die Länge der Führungsschiene 16 können je nach Türgeschwindigkeit und Türgewicht unterschiedliche Federwege eingestellt werden.Fig.2b shows an embodiment for increased claims according to Fig.2a. Instead of the elastic filling 5, an elastic cushion 17, for example made of rubber, is inserted within the tubular jacket 4 over the entire length of the guide rail 16. The tubular jacket 4 is fixed by a support profile 18, which consists of a lower part 19, an upper part 20 and a movable punch 21, and a thread 22, as in FIG. 2a. Here, too, there is the possibility of welding the tubular jacket 4 to the support profile 18. The pressure on the elastic cushion 17 can be changed by the movable plunger 21 and the thread 22, which corresponds to a reduction or an increase in the spring travel. By distributing the threads 22 over the length of the guide rail 16 different spring deflections can be set depending on the door speed and weight.

Fig.2c zeigt eine Ausführung der Führungsschiene 11, 16 nach Fig.2a und Fig.2b. Durch das Anbringen von harten, ungefederten Zonen 26 an den Stillstandspositionen der Laufrollen 1 werden kleinere Anlaufmomente erzielt und es entsteht ein geringeres Verkanten der Türflügel 56. Diese harten, ungefederten Stillstandszonen 26 können durch das Anbringen unterschiedlicher Füllungen 5 nach Fig.2a oder die Veränderung des Fülldrucks mit dem Stempel 21 nach Fig.2b erreicht werden.2a shows an embodiment of the guide rail 11, 16 according to FIGS. 2a and 2a. By attaching hard, unsprung zones 26 at the standstill positions of the rollers 1, smaller starting torques are achieved and there is less tilting of the door leaves 56. These hard, unsprung standstill zones 26 can be achieved by attaching different fillings 5 according to FIG. 2a or changing the Filling pressure can be achieved with the stamp 21 according to Fig.2b.

In Fig.3 ist eine zweite Variante der Erfindung gezeigt. Eine Laufrolle 30 mit konkaver Lauffläche 31 liegt in diesem Fall auf einer Stahlbandfeder 32 mit dachförmig abgebogener Schienenlauffläche 33, welche aus einem Blechprofil mit Federwirkung besteht. Die äussere Form der Schienenlauffläche 33 kann beliebig gewölbt, insbesondere konvex ausgebildet sein. Sie kann insbesondere aufgrund ihrer Form eine Federwirkung haben (vgl. erstes Ausführungsbeispiel). Die Stahlbandfeder 32 ist mit einer Längsseite in eine dämpfende und federnde Gummimasse 34 eingebettet. Der in die Gummimasse 34 eingebettete Abschluss 35 der Stahlbandfeder 32 kann eine beliebige Form aufweisen, welche eine gute Verbindung zwischen Gummimasse 34 und Stahlbandfeder 32 gewährleistet. Ein Tragprofil 36 aus Stahlblech dient der Aufnahme der Gummimasse 34 und als tragendes Element der Führungsschiene 37.3 shows a second variant of the invention. A roller 30 with a concave tread 31 lies in this case on a steel band spring 32 with a roof-shaped bent rail tread 33, which consists of a sheet metal profile with spring action. The outer shape of the rail running surface 33 can be curved as desired, in particular it can be convex. In particular, due to its shape, it can have a spring effect (cf. first exemplary embodiment). The steel band spring 32 is embedded with a long side in a damping and resilient rubber mass 34. The end 35 of the steel band spring 32 embedded in the rubber mass 34 can have any shape which ensures a good connection between the rubber mass 34 and the steel band spring 32. A support profile 36 made of sheet steel serves to accommodate the rubber mass 34 and as a supporting element of the guide rail 37.

Fig.4 zeigt eine Ausführung, bei welcher eine Führungsschiene 41 einen Hohlraum mit einer schlitzförmigen Öffnung 42 nach unten bildet. Die Führungsschiene 41 besteht aus zwei schalenförmigen Tragprofilen 43. Ein Auskleidungsprofil 44 im Innern der Führungsschiene 41 bildet im Bereich der Öffnung 42 eine Schienenlauffläche 45. Die Tragprofile 43 und das Auskleidungsprofil 44 sind an ihren, die Öffnung 42 bildenden Enden so abgebogen, dass eine rinnenförmige Schienenlauffläche 45 entsteht. Auskleidungsprofil 44 und Füllung 46 werden vor der Montage der beiden Tragprofilen 43 an ihnen angebracht. Zwischen den Tragprofilen 43 und dem Auskleidungsprofil 44 befindet sich eine dämpfende, elastische Füllung 46, die sich auch gemäss Fig.4 auf den unteren Teil des Hohlraumes beschränken kann. Diese Füllung 46 ist so ausgeführt, dass sie im Bereich der Öffnung 42 an dem Türflügel 56 anliegende Dichtlippen 47 bildet, um die Schienenlauffläche 45 vor Verschmutzung zu schützen. Das Auskleidungsprofil 44 ist mittels Befestigungselementen 48, z.B. Schrauben, an den Tragprofilen 43 angebracht, es kann aber auch auf die Tragprofile 43 aufgeklebt sein. Über die Schienenlauffläche 45 rollt eine, aus zwei Halbschalen 49 bestehende Laufrolle 50 mit einer mittig überhöhten Lauffläche 51. Die beiden Halbschalen 49 sind auf einer mit einem Wälzlager 59 versehenen Achse 58 angebracht. Zwischen Wälzlager 59 und Türflügel 56 befindet sich eine weitere dämpfende Einlage 52, um eine Schallausbreitung im Türflügel 56 zu verhindern.4 shows an embodiment in which a guide rail 41 forms a cavity with a slot-shaped opening 42 downwards. The guide rail 41 consists of two shell-shaped support profiles 43 Lining profile 44 in the interior of the guide rail 41 forms a rail running surface 45 in the region of the opening 42. The support profiles 43 and the lining profile 44 are bent at their ends forming the opening 42 in such a way that a channel-shaped rail running surface 45 is created. Lining profile 44 and filling 46 are attached to them before assembly of the two support profiles 43. Between the support profiles 43 and the lining profile 44 there is a damping, elastic filling 46, which according to FIG. 4 can also be limited to the lower part of the cavity. This filling 46 is designed in such a way that it forms sealing lips 47 which bear against the door leaf 56 in the region of the opening 42 in order to protect the rail running surface 45 from contamination. The lining profile 44 is attached to the support profiles 43 by means of fastening elements 48, for example screws, but it can also be glued to the support profiles 43. A roller 50 consisting of two half-shells 49 with a centrally raised tread 51 rolls over the rail running surface 45. The two half-shells 49 are mounted on an axle 58 provided with a roller bearing 59. A further damping insert 52 is located between the roller bearing 59 and the door leaf 56 in order to prevent sound propagation in the door leaf 56.
