Description

Gegenstand der Erfindung ist ein Rolltor mit einem an einem Ende auf einer angetriebenen Wickelwelle befestigten Wickelrohr zum Auf- und Abwickeln eines Behanges zum Öffnen und Verschließen einer Öffnung und einer am anderen Ende zwischen dem Wickelrohr und einer feststehenden Spannwelle vorgespannten Schraubenfeder zum Gewichtsausgleich des Behanges, wobei zwischen dem freien Ende des Behanges und dem Wickelrohr eine Spannvorrichtung mit über Umlenkrollen geführten Zugorganen angeordnet ist.The invention relates to a roller shutter with a winding tube attached at one end to a driven winding shaft for winding and unwinding a curtain for opening and closing an opening and a coil spring biased at the other end between the winding tube and a fixed tensioning shaft for weight compensation of the curtain, whereby between the free end of the curtain and the winding tube, a tensioning device with tension members guided over deflection rollers is arranged.

Aus dem DE-GM 82 06 622 ist ein Rolltor der vorstehend beschriebenen Gattung bekannt, bei dem die Spannvorrichtung für den Behang aus auf der Wickelwelle beiderseits des Wickelrohres befestigten, konischen Seilrollen und flaschenzugartig ausgebildeten Zugorganen besteht, die mit einer Zugfeder vorgespannt sind. Dabei sind die Zugfedern zwischen Umlenkrollen der Flaschenzüge und dem Fundament beiderseits der Öffnung angeordnet. Derartige Spannvorrichtungen für den Behang eines Rolltores verursachen einen erheblichen Konstruktionsaufwand und müssen aus Sicherheitsgründen mit einer Verkleidung eingekapselt werden.From DE-GM 82 06 622 a roller door of the type described above is known, in which the tensioning device for the curtain consists of conical rope pulleys fastened on the winding shaft on both sides of the winding tube and pulley-like traction elements which are prestressed with a tension spring. The tension springs are arranged between the pulleys of the pulley blocks and the foundation on both sides of the opening. Such tensioning devices for the curtain of a roller door cause a considerable construction effort and must be encapsulated with a covering for safety reasons.

Aus der DE-OS 26 44 989 ist ein Rolladen bekannt, an dessen Behang beiderseits je ein Führungsseil befestigt ist, welches über Umlenkrol-len zurück zur Wickelwelle geführt ist und dort im entgegengesetzten Wickelsinn spiralförmig auf- und abwickelbar ist, wobei die jeweiligen Wickeldurchmesser der Führungsseile und des Behanges durch konisch ausgebildete Wickelscheiben annähernd gleich groß sind. Dieser bekannte Rolladen besitzt keine Spannvorrichtung zum Ausgleich des Wegunterschiedes des Behanges und der aufgewickelten Länge der Führungsseile auf den Wickelscheiben. Deshalb besteht eine Abhängigkeit zwischen dem Durchmesser der Wickelscheiben und der Stärke des Behanges, so daß die Wickelscheiben den wechselnden Behangstärken angepaßt werden müssen. Außerdem können Längenänderungen der Führungsseile und des Behanges durch Temperaturschwankungen und Verschleiß nicht ausgeglichen werden.From DE-OS 26 44 989 a roller shutter is known, on the curtain of which a guide rope is attached on each side, which leads back to the winding shaft via deflection rollers and can be wound up and unwound spirally in the opposite winding direction, the respective winding diameters of the guide cables and the curtain being approximately the same size due to the conically shaped winding disks. This known roller shutter has no tensioning device to compensate for the difference in path of the curtain and the wound length of the guide cables on the winding disks. There is therefore a dependency between the diameter of the winding disks and the thickness of the curtain, so that the winding disks have to be adapted to the changing curtain thicknesses. In addition, changes in the length of the guide ropes and curtain cannot be compensated for by temperature fluctuations and wear.

Weiterhin ist aus der DE-OS 28 42 381 ein Rolladen für Dachfenster bekannt, dessen Behang mit einer Spannvorrichtung vorgespannt wird, für die zwei verschiedene Ausführungsbeispiele offenbart sind.Furthermore, a roller shutter for roof windows is known from DE-OS 28 42 381, the curtain of which is pretensioned with a tensioning device, for which two different exemplary embodiments are disclosed.

Im ersten Ausführungsbeispiel gemäß Fig. 3 besteht die Spannvorrichtung aus einer im Wickelrohr angeordneten Schraubenfeder, die zwischen einer mit dem Wickelrohr verbundenen Hülse und einer Welle vorgespannt ist, auf der außen zwei Aufwickelspulen für mit dem Behang verbundene Zugseile befestigt sind. Dabei ist die Verbindung zwischen der Welle und den beiden Aufwickelspulen drehfest ausgebildet. Bei dieser Anordnung kann der Behang mit der Schraubenfeder vorgespannt werden.In the first embodiment according to FIG. 3, the tensioning device consists of a helical spring arranged in the winding tube, which is pretensioned between a sleeve connected to the winding tube and a shaft, on the outside of which two winding spools for pull cables connected to the curtain are fastened. The connection between the shaft and the two winding spools is designed to be non-rotatable. With this arrangement, the curtain can be biased with the coil spring.

Bei dem zweiten Ausführungsbeispiel gemäß Fig. 5 sind die beiden Zugseile mit gegenläufig drehbar auf einer Achse angeordneten Wickelspulen verbunden, die mit einer Schraubenfeder in den entgegengesetzten Diehrichtungen vorgespannt sind. Das Drehmoment der Schraubenfeder soll im Aufspulsinne wirken, also beim Schließen des Rolladens größer und beim Öffnen des Rolladens kleiner werden. Auch bei dieser Ausführungsform ist mit der Schraubenfeder eine Vorspannung des Behanges möglich, aber die Längenänderungen der verschieden langen Zugseile können nicht ausgeglichen werden, weil die beiden Aufwickelspulen nicht relativ zueinander verstellbar, sondern drehfest auf der Welle befestigt sind.In the second exemplary embodiment according to FIG. 5, the two traction cables are connected to winding coils which are arranged in an oppositely rotatable manner on an axis and which are prestressed in the opposite direction of travel by a coil spring. The torque of the coil spring should act in the unwinding direction, i.e. they become larger when the roller shutter is closed and become smaller when the roller shutter is opened. In this embodiment, too, the curtain can be pretensioned, but the changes in length of the pull ropes of different lengths cannot be compensated for, because the two take-up reels are not adjustable relative to one another, but are fixed in a rotationally fixed manner on the shaft.

Der aus der DE-OS 28 42 381 bekannte Rolladen hat in beiden Ausführungsformen der Fig. 3 und 5 keinen getrennten Gewichtsausgleich, wie er für ein schweres Rolltor erforderlich ist.The roller shutter known from DE-OS 28 42 381 does not have a separate weight compensation in both embodiments of FIGS. 3 and 5, as is required for a heavy roller door.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Rolltor mit einer Schraubenfeder für den Gewichtsausgleich des Behanges und einer einfach konstruierten Spannvorrichtung für den Behang zu schaffen, die eine lange Lebensdauer hat und kein Sicherheitsrisiko darstellt.Based on this, the object of the invention is to create a roller door with a helical spring for balancing the weight of the curtain and a simply constructed tensioning device for the curtain, which has a long service life and does not represent a safety risk.

Als technische Lösung wird eine Spannvorrichtung vorgeschlagen, die

  • a) aus zwei an einer Seite auf einer Wickelwelle und an der anderen Seite auf der Spannwelle frei drehbar gelagerten Spannscheiben und
  • b) aus zwei vorgespannten Schenkelfedern besteht, die zwischen dem Wickelrohr und den Spannscheiben angeordnet sind.
A clamping device is proposed as a technical solution
  • a) from two on one side on a winding shaft and on the other side on the tension shaft freely rotatably mounted tension discs and
  • b) consists of two prestressed leg springs which are arranged between the winding tube and the tensioning discs.

Bei einer praktischen Ausführungsform können die Schenkelfedern versenkt in den offenen Enden des Wickelrohres angeordnet sein und mit diesen eingekapselt werden. Weiterhin wird vorgeschlagen, für die Zugorgane der Spannvorrichtung Gurte zu benutzen, deren Materialstärke etwa der Materialstärke des Behanges entspricht. Damit kann der von den Schenkelfedern zu kompensierende Längenunterschied zwischen dem Behang und den Zugorganen minimiert werden.In a practical embodiment, the leg springs can be countersunk in the open ends of the winding tube and encapsulated with them. It is also proposed to use belts for the tension members of the tensioning device, the material thickness of which corresponds approximately to the material thickness of the curtain. The length difference between the curtain and the traction elements to be compensated for by the leg springs can thus be minimized.

Bei einem nach dieser technischen Lehre ausgebildeten Rolltor ist auf der dem Antrieb abgewendeten Seite zwischen dem Wickelrohr und einer in diesem angeordneten, feststehenden Spannwelle eine vorgespannte Schraubenfeder für den Gewichtsausgleich des Behanges angeordnet. Ohne diesen Gewichtsausgleich, der beispielsweise aus dem DE-GM 82 06 622 bekannt ist, könnte der Behang des Rolltores nur mit einem entsprechend stark ausgelegten Getriebe und Antriebsmotor mit großer Geschwindigkeit auf- und abgewikkelt werden. In Verbindung mit diesem Gewichtsausgleich hat ein erfindungsgemäß ausgebildetes Rolltor den Vorteil, daß die Spannvorrichtung für den Behang mit zwei Schenkelfedern vorgespannt werden kann, die eingekapselt in einem schon vorhandenen Konstruktionsteil, nämlich dem Wickelrohr angeordnet sind und deshalb eine zusätzliche Verkleidung nicht erfordern. Außerdem werden die beiden zwischen den Spannscheiben für die Gurte und dem Wickelrohr vorgespannten Schenkelfedern nur auf Biegung beansprucht und haben deshalb eine besonders lange Lebensdauer, die auch noch durch eine Minimierung des Wegunterschiedes zwischen den Gurten und dem Behang begünstigt wird.In a roller door designed according to this technical teaching, a prestressed coil spring for balancing the weight of the curtain is arranged on the side facing away from the drive between the winding tube and a fixed tensioning shaft arranged therein. Without this counterbalance, which is known for example from DE-GM 82 06 622, the curtain of the roller shutter could only be wound up and down at high speed with a correspondingly strong gear and drive motor. In connection with this weight compensation, a roller door designed according to the invention has the advantage that the tensioning device for the curtain can be pretensioned with two leg springs which are encapsulated in an existing structural part, namely the winding tube, and therefore do not require additional cladding. In addition, the two torsion springs that are prestressed between the tensioning disks for the belts and the winding tube are only subjected to bending and therefore have a particularly long service life, which is also favored by minimizing the path difference between the belts and the curtain.

Weitere Einzelheiten und Vorteile des erfindungsgemäß ausgebildeten Rolltores ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, in der eine bevorzugte Ausführungsform schematisch dargestellt worden ist. In der Zeichnung zeigen:

  • Fig. 1 ein Rolltor mit teilweise geschnittenem Wickelrohr in Ansicht;
  • Fig. 2 dasselbe Rolltor entlang der Linie II-II in Fig. 1 geschnitten in Seitenansicht;
  • Fig. 3 dasselbe Rolltor entlang der Linie III-III in Fig. 1 geschnitten in Draufsicht.
Further details and advantages of the roller shutter designed according to the invention result from the following description of the accompanying drawing, in which a preferred embodiment has been shown schematically. The drawing shows:
  • Figure 1 is a roller shutter with a partially cut winding tube in view.
  • Figure 2 shows the same roller door along the line II-II in Figure 1 cut in side view.
  • Fig. 3 the same roller door along the line III-III in Fig. 1 cut in plan view.

Uber einem eine Öffnung 1 seitlich begrenzenden Rahmen 2 ist eine Wickelwelle 3 mit einem konzentrisch darauf befestigten Wickelrohr 4 angeordnet, mit dem ein durchsichtiger Behang 5 zum Verschließen der Öffnung 1 auf- und abgewickelt werden kann.Above a frame 2 that laterally delimits an opening 1, there is a winding shaft 3 with a winding tube 4 concentrically fastened thereon, with which a transparent curtain 5 for closing the opening 1 can be wound up and unwound.

Neben einer Antriebsmaschine 6 ist das Wickelrohr 4 mit einer nach innen versetzt angeordneten Federaufnahme 7 unmittelbar auf der Wickelwelle 3 befestigt. Vor dem offenen Ende des Wickelrohres 4 ist auf der Wickelwelle 3 eine Spannscheibe 8 für einen Gurt 9 frei drehbar gelagert. In dem Hohlraum zwischen der Federaufnahme 7 und der Spannscheibe 8 ist eine Schenkelfeder 10 untergebracht, die mit ihren Schenkelenden einerseits in die Federaufnahme 7 und andererseits in die Spannscheibe 8 eingreift. Der Gurt 9 ist über eine Umlenkrolle 11 geführt und mit einem Ende an der Spannscheibe 8 und mit seinem anderen Ende an einem mit dem Behang 5 verbundenen Querhaupt 12 befestigt. Auf diese Weise kann der Behang 5 mit der vorgespannten Schenkelfeder 10 beim Auf- und Abwickeln unter Spannung gehalten werden.In addition to a drive machine 6, the winding tube 4 is fastened directly on the winding shaft 3 with a spring receptacle 7 which is offset inwards. Before the open end of the winding tube 4, a tension pulley 8 for a belt 9 is freely rotatably mounted on the winding shaft 3. A leg spring 10 is accommodated in the cavity between the spring receptacle 7 and the tensioning disk 8 and engages with its leg ends on the one hand in the spring receptacle 7 and on the other hand in the tensioning disk 8. The belt 9 is guided over a deflection roller 11 and fastened at one end to the tensioning disk 8 and at the other end to a crosshead 12 connected to the curtain 5. In this way, the curtain 5 with the prestressed leg spring 10 can be kept under tension during winding and unwinding.

Auf der von der Antriebsmaschine 6 abgewendeten Seite ist ebenfalls eine Spannscheibe 8 mit einem Gurt 9 zum-Spannen des Behanges 5 mit einer weiteren Schenkelfeder 10 angeordnet. Diese Spannscheibe 8 ist aber nicht auf der Wickelwelle 3, sondern frei drehbar auf einer Spannwelle 13 zum Vorspannen einer Schraubenfeder 14 für den Gewichtsausgleich des Behanges 5 gelagert. Die Spannwelle 13 ist durch eine nach innen versetzt im Wickelrohr 4 befestigte Federaufnahme 15 geführt, so daß die Schenkelenden der zweiten Schenkelfeder 10 einerseits in die Spannscheibe 8 und andererseits in diese Federaufnahme 15 eingreifen können. Auf diese Weise steht auch die zweite Schenkelfeder 10 über die Federaufnahme 15, das Wickelrohr 4 und die Federaufnahme 7 mit der Wickelwelle 3 in Wirkverbindung.On the side facing away from the drive machine 6 there is also a tensioning disk 8 with a belt 9 for tensioning the curtain 5 with a further leg spring 10 arranges. However, this tensioning disk 8 is not mounted on the winding shaft 3, but is freely rotatable on a tensioning shaft 13 for biasing a helical spring 14 for balancing the weight of the curtain 5. The tensioning shaft 13 is guided through a spring receptacle 15 fixed inwards in the winding tube 4, so that the leg ends of the second leg spring 10 can engage on the one hand in the tensioning disk 8 and on the other hand in this spring receptacle 15. In this way, the second leg spring 10 is also operatively connected to the winding shaft 3 via the spring holder 15, the winding tube 4 and the spring holder 7.

Die Schraubenfeder 14 für den Gewichtsausgleich des Behanges 5 kann mit einem Spannring 16 vorgespannt werden, der am Rahmen 2 fixiert ist.The coil spring 14 for the weight compensation of the curtain 5 can be pretensioned with a clamping ring 16 which is fixed to the frame 2.

Der Behang 5 und das Querhaupt 12 greifen durch Führungen 17 in den Rahmen 2 ein, so daß ein zugdichter Abschluß der Öffnung 1 gewährleistet ist.The curtain 5 and the crosshead 12 engage through guides 17 in the frame 2, so that a tight seal of the opening 1 is guaranteed.
