Abstract

The roller door possesses a flexible door leaf which can be wound onto a winding drum (1) which is mounted rotatably above the door opening surrounded by a door frame and which is pretensioned in the winding direction by a helical torsion spring (20, 21), and an electric motor (9) which transmits a torque to the winding drum (1). So that the helical torsion spring can increase to any desired diameter without impinging on other components, and so that the torsion spring is readily visible for monitoring purposes and easily accessible for maintenance purposes and, if appropriate, for exchange, a freely rotatably mounted shaft (10) which passes through the torsion spring (20, 21) is provided which is rigidly connected with one end to the torsion spring (20, 21), while the other end of the torsion spring (20, 21) is held fixed on the frame. The shaft (10) is in drive connection with the winding drum (1) as a result of gear means (15, 16, 17).

Description

Die Erfindung betrifft ein Rolltor mit einem flexiblen Torblatt, das auf eine oberhalb der von einem Torrahmen eingefaßten Tor­öffnung drehbar gelagerten Wickeltrommel aufwickelbar ist, die von einer wendelförmigen Torsionsfeder in Aufwickelrichtung vorgespannt wird, und mit einem einen Drehantrieb auf die Wickel­trommel übertragenden Elektromotor.The invention relates to a roller door with a flexible door leaf which can be wound onto a winding drum which is rotatably mounted above the gate opening and which is biased in the winding direction by a helical torsion spring, and with an electric motor which transmits a rotary drive to the winding drum.

Bei einem aus dem DE-GM 82 06 622 bekannten Rolltor dieser Art ist die aus einem Rohr bestehende Wickeltrommel auf ihrer der Antriebsseite gegenüberliegenden Seite auf einer frei aus­kragenden rahmenfesten Achse gelagert, wobei sich die auf die Achse aufgeschobene Torsionsfeder im Innern der rohrförmigen Wickeltrommel befindet und mit ihrem einen Ende an der Wickel­trommel und mit ihrem anderen Ende an der Achse befestigt ist. Auf diese Weise bildet die Torsionsfeder eine sogenannte Absturz­sicherung. Im Falle eines Stromausfalls oder nach dem Lüften der Motorbremse bzw. nach dem Abkuppeln des Antriebes wickelt die entsprechend vorgespannte Torsionsfeder das Torblatt selbsttätig auf die Wickeltrommel auf.In a roller door of this type known from DE-GM 82 06 622, the winding drum consisting of a tube is mounted on its side opposite the drive side on a freely projecting axis fixed to the frame, the torsion spring pushed onto the axis being inside the tubular winding drum and is attached at one end to the winding drum and at the other end to the axis. In this way, the torsion spring forms a so-called fall protection. In the event of a power failure or after the motor brake has been released or after the drive has been uncoupled, the correspondingly pre-tensioned torsion spring automatically winds the door leaf onto the winding drum.

Die Anordnung von gewendelten Torsionsfedern im Innern von rohr­förmigen Wickeltrommeln ist jedoch nachteilig. Der Durchmesser der wendelförmigen Torsionsfeder muß auf den Innendurchmesser der rohrförmigen Wickeltrommel in der Weise angepaßt werden, daß diese bei ihrem größten Durchmesser die Innenwandung der Nickel­trommel möglichst nicht berührt. Denn ein Reiben der Torsions­feder an der Wandung der Wickeltrommel sollte vermieden werden, da Beschädigungen der äußeren Bereiche der wendelförmigen Torsionsfeder, in denen die größten Spannungen vorherrschen, die Lebensdauer der Torsionsfeder beträchtlich herabsetzen.However, the arrangement of coiled torsion springs in the interior of tubular winding drums is disadvantageous. The diameter the helical torsion spring must be adapted to the inside diameter of the tubular winding drum in such a way that it does not touch the inside wall of the nickel drum if possible at its largest diameter. Because rubbing of the torsion spring on the wall of the winding drum should be avoided, since damage to the outer areas of the helical torsion spring, in which the greatest stresses prevail, considerably reduce the service life of the torsion spring.

Da üblicherweise das flexible Torblatt auf dem Mantel der rohr­förmigen Wickeltrommel befestigt wird, ragen die entsprechenden Befestigungsmittel durch Bohrungen in dem Rohrmantel in den Innenraum der Wickeltrommel, so daß dadurch der zur Anordnung der Torsionsfeder vorhandene Raum weiter beengt wird. Werden aber in das Innere des Wickelrohres hineinragende Befestigungs­mittel vermieden oder wird der Überstand der Befestigungsmittel nach innen hin gering gehalten, ergeben sich zusätzliche Schwierigkeiten bei der Befestigung des Torblattes.Since the flexible door leaf is usually fastened to the jacket of the tubular winding drum, the corresponding fastening means protrude through holes in the tubular jacket into the interior of the winding drum, so that the space available for arranging the torsion spring is thereby further narrowed. However, if fasteners protruding into the inside of the winding tube are avoided or the protrusion of the fasteners towards the inside is kept small, additional difficulties arise when fastening the door leaf.

Besondere Schwierigkeiten ergeben sich weiterhin aus der Lagerung des Wickelrohres in ihrem Inneren auf der rahmenfesten Achse.Special difficulties continue to arise from the storage of the winding tube in its interior on the frame-fixed axis.

Die Anordnung von Torsionsfedern im Innern der Wickeltrommel erschwert zusätzlich auch deren Überwachung und Wartung. Eine derartige Konstruktion genügt grundsätzlich nicht den Anfor­derungen der Berufsgenossenschaft, nach denen der Sicherheit dienende Teile zur Kontrolle sichtbar und für die Wartung leicht zugänglich sein sollen.The arrangement of torsion springs inside the winding drum also complicates their monitoring and maintenance. In principle, such a construction does not meet the requirements of the professional association, according to which safety parts should be visible for inspection and easily accessible for maintenance.

Sollte die im Innern des Wickelrohres befindliche Torsionsfeder einmal brechen, ist deren Austausch schwierig und langwierig und ohne einen längeren Stillstand des Tores nicht möglich.Should the torsion spring in the inside of the winding tube break, it is difficult and lengthy to replace it and it is not possible without the gate being idle for a long time.

Aufgabe der Erfindung ist es daher, ein Rolltor der eingangs angegebenen Art zu schaffen, bei dem sich die wendelförmige Torsionsfeder in ihrem Durchmesser beliebig vergrößern kann, ohne mit anderen Konstruktionsteilen in Kollision zu geraten, und bei dem die Torsionsfeder zu ihrer Überprüfung gut sichtbar und zu ihrer Wartung und gegebenenfalls zu ihrem Austausch leicht zugänglich ist.The object of the invention is therefore to provide a roller door of the type specified, in which the helical torsion spring can increase in diameter as desired, without colliding with other structural parts, and in which the torsion spring is clearly visible and to be checked their maintenance and, if necessary, their replacement is easily accessible.

Erfindungsgemäß wird diese Aufgabe bei einem Rolltor der gattungsgemäßen Art dadurch gelöst, daß eine die Torsionsfeder durchsetzende, frei drehbar gelagerte Welle vorgesehen ist, die mit einem Ende der Torsionsfeder fest verbunden ist, während das andere Ende der Torsionsfeder rahmenfest gehalten ist, und daß die Welle durch Getriebemittel mit der Wickeltrommel in Antriebs­verbindung steht. Bei dem erfindungsgemäßen Rolltor ist die wendelförmige Torsionsfeder auf einer frei drehbaren Welle angeordnet, ohne daß konstruktiv bedingte Teile vorhanden sind, die eine Durchmesservergrößerung der Torsionsfeder behindern könnten. Die Torsionsfeder kann bei ihrer erfindungsgemäß vorge­sehenen offenen Anordnung bis auf die diese durchsetzende Welle durchhängen, ohne daß dadurch Beschädigungen der Feder eintreten können, was bei deren Anordnung in einem diese einfassenden Wickelrohr befürchtet werden mußte. Da bei dem erfindungsgemäßen Rolltor die wendelförmige Torsionsfeder in ihrem Durchmesser grundsätzlich nicht begrenzt ist, können nach Bedarf größere Federn verwendet werden, die in der rohrförmigen Wickeltrommel keinen Platz gefunden hätten. Durch die Möglichkeit, größere Torsionsfedern zu verwenden, läßt sich die Lebensdauer der Tore verlängern. Es lassen sich Torsionsfedern einsetzen, deren Lebensdauer die von von Wickeltrommeln eingefaßten Torsions­federn um ein Mehrfaches übersteigen.According to the invention this object is achieved in a roller door of the generic type in that a torsion spring passing through, freely rotatably mounted shaft is provided which is fixedly connected to one end of the torsion spring, while the other end of the torsion spring is held fixed to the frame, and that the shaft is in drive connection with the winding drum by means of a gear. In the roller door according to the invention, the helical torsion spring is arranged on a freely rotatable shaft without there being any design-related parts which could hinder an increase in the diameter of the torsion spring. The torsion spring can sag in its open arrangement according to the invention up to the shaft passing through it, without the spring being able to damage it, which had to be feared when it was arranged in a winding tube enclosing it. Since the helical torsion spring is basically not limited in its diameter in the roller door according to the invention, larger springs can be used as needed, which would not have found a place in the tubular winding drum. The possibility of using larger torsion springs extends the life of the gates. Torsion springs can be used, the service life of which is several times longer than that of the torsion springs framed by winding drums.

Auch die Konstruktion der Wickeltrommel selbst ist bei dem erfindungsgemäßen Rolltor einfacher, weil diese nur mit gleich ausgebildeten endseitigen Wellenzapfen versehen zu werden braucht, über die diese gelagert wird.The construction of the winding drum itself is simpler in the roller door according to the invention because it is only the same trained end shaft journal needs to be provided, via which it is mounted.

Die offene Anordnung der wendelförmigen Torsionsfeder auf der Spannwelle ermöglicht es, die Vorspannung der Feder ständig zu kontrollieren. Bei jeder Inspektion lassen sich die Windungen eines im ungespannten Zustand aufgebrachten Farbstriches über­prüfen. Das Auswechseln der offenliegenden Feder läßt sich einfach und schnell bewerkstelligen. Beispielsweise läßt sich der Rahmen, in dem die Welle mit der Feder gelagert ist, komplett auswechseln.The open arrangement of the helical torsion spring on the tensioning shaft makes it possible to constantly control the preload of the spring. With each inspection, the turns of an uncoated color line can be checked. The open spring can be replaced quickly and easily. For example, the frame in which the shaft with the spring is mounted can be completely replaced.

Die auf der Spannwelle gehalterte Feder kann durch ein aufge­setztes Gehäuse abgedeckt sein, das sich bei Inspektions- und Wartungsarbeiten leicht und schnell entfernen läßt.The spring held on the tensioning shaft can be covered by an attached housing, which can be easily and quickly removed during inspection and maintenance work.

Zweckmäßigerweise ist die Welle im Abstand parallel zu der Wickeltrommel gelagert, wobei beide durch einen Kettentrieb miteinander gekuppelt sind. Dabei besteht der Kettentrieb aus auf die Welle und die Wickeltrommel bzw. deren Wellenzapfen aufgekeilten Kettenrädern, die von einer endlosen Kette umschlungen sind.The shaft is expediently mounted at a distance parallel to the winding drum, both being coupled to one another by a chain drive. The chain drive consists of chain wheels which are wedged onto the shaft and the winding drum or their shaft journals and which are wrapped in an endless chain.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß auf die Welle zwei Torsionsfedern aufgeschoben sind, deren innere Enden fest mit der Welle und deren äußeren Enden im Bereich der Wellenlager rahmenfest gehalten sind. Derartige Tandemfedern erhöhen die Sicherheit, weil nicht zu erwarten ist, daß beide gleichzeitig brechen, so daß im Falle eines Bruchs der einen Feder immer noch die andere wirksam bleibt.In a further embodiment of the invention it is provided that two torsion springs are pushed onto the shaft, the inner ends of which are fixed to the shaft and the outer ends of which are fixed to the frame in the region of the shaft bearings. Such tandem springs increase safety because it is not expected that both will break at the same time, so that if one spring breaks, the other remains effective.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt

  • Fig.1 eine Draufsicht auf das Rolltor,
  • Fig.2 eine Seitenansicht der Wickeltrommel und der Federspann­welle in Richtung des Pfeils A in Fig.1,
  • Fig.3 eine Ansicht des oberen Teils des Rolltors in Richtung des Pfeils B in Fig. 1 und
  • Fig.4 eine der Fig.3 entsprechende Ansicht des Rolltors, bei dem die Federspannwelle oberhalb der Wickeltrommel angeordnet ist.
An embodiment of the invention is explained below with reference to the drawing. In this shows
  • 1 is a plan view of the roller door,
  • 2 shows a side view of the winding drum and the spring tension shaft in the direction of arrow A in FIG. 1,
  • 3 is a view of the upper part of the roller door in the direction of arrow B in Fig. 1 and
  • 4 shows a view of the roller door corresponding to FIG. 3, in which the spring tensioning shaft is arranged above the winding drum.

Die Wickeltrommel 1 ist an beiden Seiten mit Wellenzapfen 2,3 verbunden, die in Lagern 4,5 von mit dem Torrahmen verbundenen Seitenteilen gelagert sind. Auf den Wellenzapfen 4 ist ein Kettenrad 6 aufgekeilt, das von einer Kette 7 angetrieben wird, die über das Antriebskettenrad 8 des Getriebemotors 9 läuft, der über ein abgewinkeltes Tragstück mit einer an dem Torrahmen befestigten Seitenwand verbunden ist. Parallel zu der Wickel­trommel 1 ist die Federspannwelle 10 in Lagern 11,12 frei drehbar gelagert, die an mit dem Torrahmen verbundenen Trag­stücken und Seitenwänden vorgesehen sind. Das Tragstück 13 des Lagers 11 ist an einer mit dem Torrahmen bzw. Seitenteilen des Torrahmens verbundenen Traverse 14 befestigt. Auf das aus Fig. 1 ersichtliche rechte Ende der Spannwelle und auf das Ende des Wellenzapfens 3 der Wickeltrommel 4 sind Kettenräder 15,16 aufgekeilt, über die die endlose Kette 17 läuft. Im mittleren Bereich der Welle 10 sind zwei Federteller 18,19 befestigt, an denen die inneren Enden der wendelförmigen Torsionsfedern 20,21 fixiert sind. Die äußeren Enden der Federn 20,21 sind an den gestellfesten Teilen der Lager 12,13 festgelegt.The winding drum 1 is connected on both sides with shaft journals 2, 3, which are supported in bearings 4, 5 by side parts connected to the goal frame. On the shaft journal 4, a sprocket 6 is keyed, which is driven by a chain 7, which runs over the drive sprocket 8 of the geared motor 9, which is connected via an angled support piece to a side wall attached to the goal frame. Parallel to the winding drum 1, the spring tension shaft 10 is freely rotatably supported in bearings 11, 12 which are provided on support pieces and side walls connected to the goal frame. The support piece 13 of the bearing 11 is attached to a cross member 14 connected to the goal frame or side parts of the goal frame. On the right end of the tension shaft shown in FIG. 1 and on the end of the shaft journal 3 of the winding drum 4, sprockets 15, 16 are wedged over which the endless chain 17 runs. In the central area of the shaft 10, two spring plates 18, 19 are fastened, on which the inner ends of the helical torsion springs 20, 21 are fixed. The outer ends of the springs 20, 21 are fixed to the parts of the bearings 12, 13 fixed to the frame.

Die Federspannwelle 10 ist um so viel kürzer als die Wickel­trommel 1, daß der Getriebemotor 9 fluchtend zu dieser angeordnet werden kann, was eine raumsparende Anordnung ermöglicht. Da ohnehin Raum für den Getriebemotor 9 vorgesehen werden muß, führt die parallele Anordnung der Federspannwelle 10 grundsätzlich nicht zu einer vergrößerten Bauweise.The spring tension shaft 10 is so much shorter than the winding drum 1 that the gear motor 9 is aligned with this can be arranged, which allows a space-saving arrangement. Since space must be provided for the geared motor 9 anyway, the parallel arrangement of the spring tension shaft 10 does not in principle lead to an enlarged construction.

Bei der Seitenansicht nach Fig. 2 sind der besseren Ubersicht­lichkeit halber die wendelförmigen Torsionsfedern 20,21 wegge­lassen worden.In the side view according to FIG. 2, the helical torsion springs 20, 21 have been omitted for the sake of clarity.

Bei dem Ausführungsbeispiel nach den Fig. 1 bis 3 sind die Wickelwelle 1 und die Federspannwelle 10 in Gehäusekästen in einer horizontalen Ebene angeordnet.In the embodiment of FIGS. 1 to 3, the winding shaft 1 and the spring tension shaft 10 are arranged in housing boxes in a horizontal plane.

Bei dem Ausführungsbeispiel nach Fig.4 befindet sich die Feder­spannwelle oberhalb der Wickelwelle, wobei beide in einer vertikalen Ebene liegen.In the embodiment of Figure 4, the spring tension shaft is above the winding shaft, both of which lie in a vertical plane.

Auf die Wickeltrommel 1 ist das flexible Torblatt 25 aufwickelbar, das an seinem unteren Ende mit einem dieses spannenden Abschlußprofil 26 versehen ist.On the winding drum 1, the flexible door leaf 25 can be wound, which is provided at its lower end with an exciting end profile 26.
