Definitions
- the invention relates to a roller door according to the preamble of patent claim 1.
- a generic roller door is from the EP-B1 0531320 known that avoids these disadvantages by means of a planned in the lintel double guide.
- the door leaf is pushed up into the guide.
- This construction has the disadvantage that the driving force must be set at the bottom.
- the drive must be done in this known goal very complicated on the bottom end-fin, since the door leaf will be inserted into a helically shaped guideway. Due to the complicated guideway, the gate has a disadvantageously high noise emission. In addition, the complicated structure tends to noise.
- a similar goal is in the DE 40 15 214 A1 specified.
- each arranged in the wound state between two winding layers lamella at least one support body, or, each of which a support surface pair with an outside support surface and an inside support surface has.
- individual slats such as the bottom slats in the closed state, which are not wound in the open position or form the outer winding layer without support body or perform with such support bodies having only an inside support surface.
- the lamellae forming the inner winding layer can be designed without a support body or be equipped with support bodies which have only one outer support surface.
- the connecting elements with the support surfaces can be attached, for example, to the ends of a lamella running as a hollow profile and connect permanently with this in a suitable manner.
- the supporting bodies designed in the form of connecting elements have a double function.
- the same purpose serves the measure that at least one device is provided with which a force is generated as an aid in accelerating and decelerating the door leaf.
- a force is generated as an aid in accelerating and decelerating the door leaf.
- a weight can be used to generate the force.
- the entry and exit of the door leaf from the vertical guide tracks is advantageously facilitated by the winding axis has a distance from the vertical guide plane formed by the guideways, which is formed according to the current winding radius. The distance thus changes automatically during winding. The door leaf therefore runs tangentially bum-free from the winding into or out of the guideways.
- Fig. 1 is shown as a side view of the roller shutter according to the invention schematically. It consists of a plurality of vertically aligned slats 2 ( Fig. 3 ), which extend horizontally over the entire door width and thus form the door leaf 3. At their ends, the slats are firmly connected with connecting elements 4. The connecting elements 4 together form a chain whose end is fixed to a winding disk 5 by means of a bolt 6.
- the fulcrum of the take-up disc 5 determines with the main shaft a winding axis 16, the distance 17 is formed by a particular of the guideways Torblattebene 18 by the bearings of the main shaft 16 are guided horizontally displaceable.
- Fixed to the bearing of the Wichelwelle 16 is the bearing of a gear 19 which engages in a stationary horizontal tensioned chain 20.
- Rotationally connected to gear 19 a further gear 21 is connected, which is looped by an endless chain 22.
- This chain is driven by a pinion of the drive, not shown, of the winding shaft or, as shown here, directly from a pinion 23 connected to the winding shaft.
- the translation is chosen so that with one revolution of the winding shaft during winding, their distance to the door leaf level 18 is increased by the support surface distance so that the Torblattebene 18 remains tangent to the current Aufwickelradius.
- mass can also be used attached to the belt 29 spring, in particular tension or torsion spring.
- the sealing lips provided on a lamella side come to rest against corresponding mating surfaces of the neighboring profile.
- the door leaf is thus particularly dense and mechanically strong.
- Fig. 8 shows an alternative embodiment of the seal between two adjacent fins.
- a bar 42 is integrally formed on a longitudinal side of the blade, which engages in the formed by a shorter web 40 and a longer web, outer web 41 groove 43. Due to the different lengths of the webs 40, 41, the slats 2 can be pivoted against each other.
- a the bar 42 U-shaped enveloping plastic profile 44 prevents at all tilt angles that the blades touch directly. This avoids noise, achieves effective sealing and realizes a sliding articulation.
Abstract
Description
Die Erfindung betrifft ein Rolltor nach der Oberbegriff des Patentanspruchs 1.The invention relates to a roller door according to the preamble of patent claim 1.
Rolltore sind in verschiedenen Ausführungen bekannt. In einer beispielsweise in der
Ein gattungsgemäßes Rolltor ist aus der
Ferner ist in der
Aufgabe der Erfindung ist es deshalb, die Lärmemission zu senken, die Betriebssicherheit des gattungsgemäßen Rolltores zu verbessern und eine Beeinträchtigung des äußeren Erscheinungsbildes der Lamellen zu vermeiden.The object of the invention is therefore to reduce the noise emission, to improve the reliability of the generic roller door and to avoid an impairment of the external appearance of the slats.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Weiterbildung herkömmlicher Rolltore gelöst . Zum Erhalt einer besonders zuverlässigen Vermeidung von Beschädigungen der Lamellen und zum Erhalt einer wirkungsvollen Reduktion der Lärmemission weist jede im aufgewickelten Zustand zwischen zwei Wickellagen angeordnete Lamelle mindestens einen Stützkörper auf, der, oder, von denen jeder ein Stützflächenpaar mit einer außenseitigen Stützfläche und einer innenseitigen Stützfläche besitzt. Im Rahmen der Erfindung ist es ohne Beeinträchtigung der Betriebssicherheit und ohne Erhöhung der Lärmemission möglich, einzelne Lamellen, wie etwa die im Schließzustand untersten Lamellen, die in der Öffnungsstellung nicht aufgewickelt sind oder die äußere Wickellage bilden ohne Stützkörper oder mit solchen Stützkörpern auszuführen, die lediglich eine innenseitige Stützfläche aufweisen. Ebenso können die die innere Wickellage bildenden Lamellen ohne Stützkörper ausgeführt sein oder mit solchen Stützkörpern ausgestattet sein, die nur eine äußere Stützfläche besitzen.This object is achieved by the specified in claim 1 training conventional roller doors. To obtain a particularly reliable avoidance of damage to the slats and to obtain an effective reduction of noise emission, each arranged in the wound state between two winding layers lamella at least one support body, or, each of which a support surface pair with an outside support surface and an inside support surface has. In the context of the invention, it is without affecting the reliability and without increasing the noise emission possible, individual slats, such as the bottom slats in the closed state, which are not wound in the open position or form the outer winding layer without support body or perform with such support bodies having only an inside support surface. Likewise, the lamellae forming the inner winding layer can be designed without a support body or be equipped with support bodies which have only one outer support surface.
In den meisten Fällen einer besonders vorteilhaften Ausgestaltung der Erfindung reicht es aus, daß die Stützflächen an den seitlichen Enden der Lamellen des Torblattes, vorzugsweise auf die Lamelle seitlich haltenden Verbindungselementen, angeordnet sind. Zusätzliche Stützflächen sind nur dann notwendig, wenn das Torblatt so breit ist, daß der Wickel instabil wird, oder eine Dämpfung auftretender Biegeschwingungen außerhalb der Schwingungsknoten erfolgen soll. Grundsätzlich können jedoch die Stützflächen und die Verbindungselemente voneinander getrennt sein. Beispielsweise können die Lamellen durch Scharniere miteinander verbunden sein und die Stützflächen auf den Lamellen vorgesehen werden.In most cases, a particularly advantageous embodiment of the invention, it is sufficient that the support surfaces are arranged at the lateral ends of the slats of the door leaf, preferably on the slat side holding fasteners. Additional support surfaces are only necessary if the door leaf is so wide that the winding is unstable, or an attenuation occurring bending vibrations should be outside the nodes. In principle, however, the support surfaces and the connecting elements can be separated from each other. For example, the slats can be connected to each other by hinges and the support surfaces are provided on the slats.
Besonders leise läßt sich das Torblatt dann aufrollen, wenn die Stützflächen um die Wickelachse gekrümmt ausgebildet sind. Mit wachsendem Aufwickelradius muß deshalb auch der Krümmungsradius entsprechend sich vergrößern. Es reicht jedoch in der Praxis meist ein mittlerer Radius aus, um ein ausreichend gleichmäßiges Aufrollen zu gewährleisten, insbesondere dann, wenn auf der Stützfläche noch ein nachgiebiges, insbesondere elastisches Dämpfungsmaterial aufgebracht ist. Die Verbindungselemente können mit Vorteil auch die Lamellen beim Aufrollen führen, wenn die Stützflächen quer zur Bewegungsrichtung auf einer Seite konvex und auf der anderen Seite konkav ausgebildet sind.The door leaf can then be rolled up particularly quietly when the support surfaces are curved around the winding axis. Therefore, as the winding radius increases, the radius of curvature must also increase accordingly. However, in practice, it is usually sufficient to have a medium radius in order to ensure sufficiently uniform rolling, in particular when a yielding, in particular elastic damping material is applied to the support surface. The connecting elements can advantageously also lead the slats when rolling when the support surfaces are formed transversely to the direction of movement convex on one side and concave on the other side.
Zusätzliche Gelenke lassen sich vorteilhaft vermeiden, wenn, die Lamellen fest mit den zur Bildung einer Kette gelenkig miteinander verbundenen Verbindungselemente verbunden sind. Die Verbindungselemente mit den Stützflächen lassen sich beispielsweise auf die Enden einer als Hohlprofil ausgeführten Lamelle aufstecken und mit diesem auf geeignete Weise dauerhaft verbinden. In diesem Fall kommt den in Form von Verbindungselementen ausgeführten Stützkörpern eine Doppelfunktion zu. Zum einen wird damit eine gelenkige Verbindung zwischen den einzelnen Lamellen hergestellt und zum anderen wird damit das Aufeinanderprallen der im aufgewickelten Zustand in benachbarten Wickellagern angeordneten Lamellen verhindert.Additional joints can be advantageously avoided if, the fins are firmly connected to the articulated interconnected to form a chain connecting elements. The connecting elements with the support surfaces can be attached, for example, to the ends of a lamella running as a hollow profile and connect permanently with this in a suitable manner. In this case, the supporting bodies designed in the form of connecting elements have a double function. On the one hand, an articulated connection between the individual lamellae is thus produced and, on the other hand, the collision of the lamellae arranged in wound-on bearings in the wound-up state is thus prevented.
Es reicht dann aus, wenn nur die Verbindungselemente Führungselemente, wie etwa Führungsrollen zur Führung der Torblattbewegung aufweisen und vorzugsweise die Verbindungselemente mittels Kettengelenken zu einer Kette verbunden sind.It is sufficient if only the connecting elements guide elements, such as guide rollers for guiding the Torblattbewegung have and preferably the connecting elements are connected by means of chain links to a chain.
Dadurch, daß zwei benachbarte Lamellen eine gemeinsame Schwenkachse aufweisen, die mit der Achse der Kettengelenke und vorzugsweise mit der Achse der Führungsrollen fluchtend ausgebildet sind, existiert die gemeinsame Schwenkachse nur konstruktiv aber nicht körperlich. Die gemeinsame Schwenkachse wird durch die Gelenkachse der Verbindungselemente gebildet.Characterized in that two adjacent lamellae have a common pivot axis, which are formed aligned with the axis of the chain links and preferably with the axis of the guide rollers, the common pivot axis exists only constructive but not physically. The common pivot axis is formed by the hinge axis of the connecting elements.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß in der vertikalen Ebene am horizontalen Ort der Stützflächenpaare mindestens eine Aufwickelscheibe vorgesehen ist, die eine spiralförmige Umfangsfläche aufweist, deren Spiralsteigung so bemessen ist, daß sie dem Abstand der Stützflächen eines Stützflächenpaares entspricht. An die Stufe dieser Aufwickelscheibe, die durch die Steigung entsteht, wird das obere Ende der das Torblatt tragenden Kette angebracht. Auf diese Weise entsteht beim Aufwickeln eine praktisch stetige Fläche auf die die Kette aufgewickelt wird, ohne dabei Stöße zu erzeugen. Solche Stöße bewirken im Dauerbetrieb eine nachteilig hohe Lärmemission und mechanische Belastung der Torkonstruktion.In a further advantageous embodiment of the invention, it is provided that in the vertical plane at the horizontal location of the support surface pairs at least one take-up is provided which has a spiral peripheral surface whose spiral pitch is dimensioned so that it corresponds to the distance of the support surfaces of a support surface pair. At the stage of this take-up disc, which is formed by the slope, the upper end of the door leaf-bearing chain is attached. In this way, when winding up a practically continuous surface on which the chain is wound without creating shocks. Such impacts cause in continuous operation a disadvantageous high noise emission and mechanical stress on the door construction.
Mit Vorteil kann die Leistung des Antriebs geringer ausgelegt werden, wenn eine Vorrichtung mit einer Zugfeder zur Kompensation des nicht aufgewickelten Torblattgewichts vorgesehen ist.Advantageously, the power of the drive can be made smaller, if a device is provided with a tension spring to compensate for the unwound Torblattgewichts.
Demselben Zweck dient die Maßnahme, daß mindestens eine Vorrichtung vorgesehen ist, mit der eine Kraft als Hilfe beim Beschleunigen und Verzögern des Torblatts erzeugt wird. Bei breiteren Toren ist es zur Vermeidung von nachteilig wirkenden Torsionskräften auf den Wickel vorteilhaft, wenn diese Vorrichtungen paarweise an den Enden des Wickels vorgesehen werden. Dabei kann zum Erzeugen der Kraft ein Gewicht eingesetzt werden.The same purpose serves the measure that at least one device is provided with which a force is generated as an aid in accelerating and decelerating the door leaf. For wider gates, it is advantageous to avoid disadvantageously acting torsional forces on the reel when these devices are provided in pairs at the ends of the reel. In this case, a weight can be used to generate the force.
Getrennte Vorrichtungen zur Unterstützung entweder des Verzögerns oder des Beschleunigens des Türblattes lassen sich mit Vorteil vermeiden, wenn die Kraft, wie etwa die Gleichgewichtskraft ihre Wirkrichtung während des Öffnens oder Schließens des Torblattes ändert.Separate devices to aid in either retarding or accelerating the door panel can be advantageously avoided when the force, such as the balance force, changes its direction of action during opening or closing of the door panel.
Das Ein- und Auslaufen des Torblattes aus den vertikalen Führungsbahnen wird vorteilhaft dadurch erleichtert, daß die Wickelachse einen Abstand zur von den Führungsbahnen gebildeten vertikalen Führungsebene aufweist, der dem momentanen Wickelradius entsprechend ausgebildet ist. Der Abstand ändert sich während des Wickelns also selbsttätig. Das Torblatt läuft deshalb tangential stoßfrei vom Wickel in die Führungsbahnen hinein oder aus diesen heraus.The entry and exit of the door leaf from the vertical guide tracks is advantageously facilitated by the winding axis has a distance from the vertical guide plane formed by the guideways, which is formed according to the current winding radius. The distance thus changes automatically during winding. The door leaf therefore runs tangentially bum-free from the winding into or out of the guideways.
Der Abstand läßt sich mit Vorteil zwangsweise verstellen, wenn der Antrieb zur Verlagerung der Wickelwelle vom Wickelantrieb über ein Getriebe abgeleitet wird. Konstruktiv einfach und vorteilhaft sicher stellt sich eine Ausgestaltung dar, bei der die Wickelwelle einen festen Abstand zu einem Zahnrad aufweist, das in einer linear gespannten Kette eingreifend angeordnet ist. Als Kette läßt sich beispielsweise eine handelsübliche Fahrradkette mit entsprechendem Ritzel verwenden.The distance can be adjusted forcibly with advantage if the drive for the displacement of the winding shaft is derived from the winding drive via a transmission. Constructively simple and advantageous safe is an embodiment in which the winding shaft has a fixed distance to a gear which is arranged engaging in a linearly tensioned chain. As a chain can be used, for example, a commercial bicycle chain with a corresponding pinion.
Beschädigungen in den Führungen und am Torblatt, sowie gefährliche Unfälle im Betrieb mit Fahrzeugen lassen sich entschärfen, wenn die Führungsbahnen bei Überschreiten einer bestimmten quer zur Torblattebenen wirkenden Kraft ausweichend ausgebildet sind. Kann ein Fahrzeug nicht rechtzeitig vor dem Tor anhalten, so gibt das Tor bei dem entstehenden Aufprall nach, da die Führungsbahnen das Tor dann freigeben.Damage in the guides and on the door leaf, as well as dangerous accidents during operation with vehicles can be defused if the guideways are designed evasive when exceeding a certain transversely acting to the door leaf levels force. If a vehicle can not stop in time in front of the goal, the goal gives way in the event of an impact, as the guideways then release the goal.

Rechts und links vom Torblatt 3 sind Führungsbahnen 7 angeordnet, in denen die Verbindungselemente 2 etwa vertikal und horizontal mittels an den Verbindungselementen vorgesehenen Führungsrollen 8 geführt werden.
Bei der in der Zeichnung dargestellten Ausführungsform der Erfindung weist jedes Verbindungselement 4 (
Im dargestellten Beispiel fluchten die Gelenkachse 12 (
Die Aufwicketscheibe 5 weist eine spiralige äußere Umfangsfläche 14 auf, so daß eine Stufe 15 entsteht. Die Höhe der Stufe entspricht dabei vorzugsweise etwa dem Abstand des Stützflächenpaares 11, so daß sich die Umfangsfläche beim Aufwickeln in der äußeren Stützfläche 10 der Verbindungselemente 4 fortsetzt. Nach einer vollen Umdrehung der Aufwickelscheibe 5 kommen dann die inneren Stützflächen 9 auf den äußeren Stützflächen 10 des vorherigen Wickels zur Anlage. Aufgrund des Stützflächenabstandes berühren sich die Lamellen jedoch nicht, so daß Prall- und Stoßeffekte unterbleiben.The
Der Drehpunkt der Aufwickelscheibe 5 bestimmt mit der Hauptwelle eine Wickelachse 16, deren Abstand 17 von einer von den Führungsbahnen bestimmten Torblattebene 18 veränderbar ausgebildet ist, indem die Lager der Hauptwelle 16 horizontal verschieblich geführt sind. Fest mit dem Lager der Wichelwelle 16 ist das Lager eines Zahnrades 19, das in eine ortsfeste horizontal gespannte Kette 20 eingreift. Drehfest mit Zahnrad 19 ist ein weiteres Zahnrad 21 verbunden, das von einer Endloskette 22 umschlungen ist. Diese Kette wird von einem Ritzel des nicht dargestellten Antriebs der Wickelwelle oder, wie hier dargestellt, direkt von einem mit der Wickelwelle verbundenen Ritzel 23 angetrieben. Die Übersetzung ist so gewählt, daß mit einer Umdrehung der Wickelwelle beim Aufwickeln, ihr Abstand zur Torblattebene 18 um den Stützflächenabstand so vergrößert wird, die Torblattebene 18 tangential zum momentanen Aufwickelradius bleibt.The fulcrum of the take-up
Zur Kompensation des abgewickelten Torblattgewichts ist auf der Wickelwelle drehfest mit dieser eine Wickeltrommel 24 verbunden, auf der ein Gurt 25 befestigt ist, dessen andres Ende über Umlenkrollen 38 und 26 an einer Zugfeder 27 befestigt ist. Die Federkennlinie der Zugfeder 27 und der Durchmesser der Wickeltrommel 24 ist so aufeinander abgestimmt, daß das momentane Torblattgewicht weitgehend kompensiert wird. Der Wickelsinn ist so gewählt, daß sich der Gurt beim Aufwickeln des Torblattes abwickelt. Die Zugfeder verkürzt sich dadurch und zusätzlich durch den sich verringernden Abstand der Wicleelwelle 16 von der Umlenkrolle 38, so daß ihre Zugkraft entsprechend abnimmt. Gleichermaßen nimmt das Gewicht des noch abgewickelten Torblattes ab.To compensate for the unwound Torblattgewichts a winding
Da häufig derartige Rolltore möglichst schnell öffnen oder schließen sollen, können erhebliche Beschleunigungs- oder Verzögerungskräfte entstehen, für die der Antrieb ausgelegt sein muß. Zur Unterstützung des Antriebs ist deshalb eine Vorrichtung vorgesehen, die aus einer Masse 28 besteht, deren Kraft mittels eines Gurtes 29 und einer oberen Umlenkrolle 30 und einer unteren Umlenkrolle 31 sowie mittels eines Blockes 32 an ihren Angriffspunkt am unteren Ende des Torblattes geführt ist. Ein Ende des Gurtes 29 ist ortsfest oberhalb von Masse 28 befestigt, das andere Ende am Türblatt. Der Gurt 29 bildet von seinem ortsfesten Ende kommend zunächst eine Bucht um Block 32, an dem die Masse 28 angreift. Danach ist der Gurt zwischen den etwa in ¾ Höhe des Torblattes ortsfest angeordneten Umlenkrollen 30, 31 hindurch zum Torblattende geführt. Solange das Torblattende sich unterhalb der Umlenkrolle 31 befindet, wirkt die Kraft des Gurtes 29 nach oben und unterstützt beschleunigend dadurch das Öffnen bzw. verzögert das Schließen des Torblattes. Sobald der Befestigungsort des Gurtes 29 oberhalb der Höhe der Rolle 31 liegt, wirkt die Kraft des Gurtes 29 nach unten, so daß das Öffnen des Torblattes verzögert wird. Diese Situation ist durch eine unterbrochene Linienführung des Gurtes 29 in
Anstelle der Masse kann auch eine an dem Gurt 29 befestigte Feder, insbesondere Zug- oder Torsionsfeder eingesetzt werden.Instead of the mass can also be used attached to the
Aufgrund der speziellen Ausgestaltung kommen die an einer Lamelleseite vorgesehenen Dichtlippen an entsprechenden Gegenflächen des Nachbarprofils zur Anlage. Das Torblatt ist dadurch besonders dicht und mechanisch fest.Due to the special configuration, the sealing lips provided on a lamella side come to rest against corresponding mating surfaces of the neighboring profile. The door leaf is thus particularly dense and mechanically strong.
Auf diese Weise ist ein Rolltor geschaffen, das bei minimaler Geräuscheemission ein besonders schnelles Öffnen und Schließen zuläßt. Durch den überraschend einfachen konstruktiven Aufbau weist es auch eine besonders geringe Störanfälligkeit auf.In this way, a roller shutter is created that allows a very fast opening and closing with minimal noise emission. Due to the surprisingly simple structural design, it also has a very low susceptibility to interference.
