Description

Die Erfindung betrifft ein Rolltor nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a roller door according to the preamble of patent claim 1.

Rolltore dieser Art werden insbesondere zum Verschließen von Halleneinfahrten eingesetzt. Dabei kann das Schließelement bei Übergang von der Schließstellung in die Öffnungsstellung auf einer über der Halleneinfahrt angeordneten Wickelwelle aufgewickelt werden. Dadurch wird eine platzsparende Unterbringung des Schließelementes in der Öffnungsstellung gewährleistet. Zu diesem Zweck kann das Schließelement in Form eines sog. Lamellenpanzers mit einer Vielzahl von bzgl. senkrecht zur Bewegungsrichtung des Schließelementes verlaufenden Gelenkachsen gelenkig miteinander verbundenen Lamellen gebildet sein. In Fällen, bei denen es weniger auf einen einbruchssicheren Abschluß der Einfahrt, als auf eine schnelle Öffnung der Einfahrt ankommt, kann das Schließelement auch in Form eines bahnförmigen Behangs, beispielsweise aus PVC bestehen. Zur Unterstützung der Öffnungsbewegung wird in der Regel eine Gewichtsausgleichseinrichtung eingesetzt, mit der das Schließelement aus der Schließstellung nach oben in Richtung auf die Öffnungsstellung gedrängt wird. Eine derartige Gewichtsausgleichseinrichtung kann die im Verlauf der Schließbewegung des Schließelementes frei werdende Energie aufnehmen, die später zur Unterstützung der Öffnungsbewegung zur Verfügung steht. Derartige Gewichtsausgleichseinrichtungen können in Form von Federanordnungen, insbesondere Zug- und/oder Torsionsfederanordnungen verwirklicht werden, welche im Verlauf der Schließbewegung gespannt und im Verlauf der Öffnungsbewegung wieder entspannt werden. Alternativ oder zusätzlich können die Gewichtsausgleichseinrichtungen auch Gewichte aufweisen, welche im Verlauf der Schließbewegung des Schließelementes angehoben und im Verlauf der Öffnungsbewegung wieder abgesenkt werden.Roller doors of this type are used in particular for closing hall entrances. In this case, the closing element can be wound in transition from the closed position to the open position on a winding shaft arranged above the hall entrance. This ensures a space-saving storage of the closing element in the open position. For this purpose, the closing element in the form of a so-called. Lamellenpanzers with a plurality of respect. Vertically to the direction of movement of the closing element extending hinge axes hingedly interconnected slats may be formed. In cases where it is less on a burglar - proof completion of Entrance, as depends on a quick opening of the driveway, the closing element can also be in the form of a web-shaped curtain, for example made of PVC. To assist the opening movement, a weight compensation device is generally used with which the closing element is urged from the closed position upwards in the direction of the open position. Such a weight compensating device can absorb the energy released in the course of the closing movement of the closing element, which energy is later available for assisting the opening movement. Such weight compensation devices can be realized in the form of spring arrangements, in particular tension and / or torsion spring arrangements, which are tensioned in the course of the closing movement and relaxed again in the course of the opening movement. Alternatively or additionally, the weight compensation devices may also have weights which are raised in the course of the closing movement of the closing element and lowered again in the course of the opening movement.

Bei der Dimensionierung der Gewichtsausgleichseinrichtung muß insbesondere bei Rolltoren mit einem Schließelement in Form eines bahnförmigen Behangs darauf geachtet werden, daß zu Beginn der Schließbewegung zunächst ein beachtliches Losbrechmoment des Antriebs überwunden werden muß, während danach nur ein vergleichsweise geringes Moment zur Weiterführung der Öffnungsbewegung erforderlich ist. Dieses Losbrechmoment beträgt typischerweise 15 Nm oder mehr, während zur Weiterführung der Bewegung üblicherweise ein Moment von nur 2 bis 3 Nm benötigt wird. Dementsprechend muß die Gewichtsausgleichseinrichtung so dimensioniert sein, daß sie ein entsprechend hohes Losbrechmoment zur Verfügung stellt. Im Verlauf der Öffnungsbewegung wird das Schließelement entsprechend dem Losbrechmoment beschleunigt und muß bei Erreichen der Öffnungsstellung entsprechend abgebremst werden, um Beschädigungen des Antriebs, des Schließelementes und/oder der Wickelwelle zu vermeiden. Alternativ können die genannten Elemente auch so dimensioniert werden, daß Beschädigungen auch beim abrupten Abstoppen der Öffnungsbewegung nicht auftreten. Die beiden vorstehend beschriebenen Möglichkeiten bedingen jedoch einen hohen konstruktiven Aufwand zur Vermeidung von Beschädigungen des Rolltors. Zur Lösung dieses Problems werden in der DE-U-202 04 637 Rolltore vorgeschlagen, bei denen die Gewichtsausgleichseinrichtung mindestens ein Ausgleichselement aufweist, mit dem das Schließelement in der Schließstellung in die Öffnungsstellung gedrängt wird und das die Öffnungsbewegung beim Erreichen der Öffnungsstellung wieder abbremst. Der Offenbarungsgehalt der genannten Schrift wird hinsichtlich der Ausführung von Gewichtsausgleichseinrichtungen hiermit durch ausdrückliche Inbezugnahme in diese Beschreibung aufgenommen.When dimensioning the weight balancing device, particular care must be taken in the case of roller shutters with a closing element in the form of a sheet-like curtain that a considerable breakaway torque of the drive must be overcome at the beginning of the closing movement, whereas thereafter only a comparatively small moment is required to continue the opening movement. This breakaway torque is typically 15 Nm or more, while to continue the movement usually a torque of only 2 to 3 Nm is needed. Accordingly, the weight balancing device must be dimensioned so that it provides a correspondingly high breakaway torque available. In the course of the opening movement, the closing element is accelerated in accordance with the breakaway torque and must be braked accordingly upon reaching the open position to avoid damage to the drive, the closing element and / or the winding shaft. Alternatively, the said elements can also be dimensioned so that damage does not occur even when abrupt stopping the opening movement. However, the two options described above require a high design effort to avoid damage to the roller shutter. To solve this problem, DE-U-202 04 637 proposed roller shutters in which the weight compensation device has at least one compensating element with which the closing element is urged in the closed position into the open position and which brakes the opening movement when reaching the open position again. The disclosure of the cited document is with regard to the execution of weight compensation devices hereby incorporated by express reference in this description.

Beim Einsatz von Rolltoren mit einem Schließelement in Form eines bahnförmigen Behangs ist üblicherweise am unteren Rand des bahnförmigen Behangs ein Stabilisierungselement vorgesehen. Mit diesem Stabilisierungselement wird einerseits die Form des unteren Randes des bahnförmigen Behangs stabilisiert, um so einen definierten Abschluß des Schließelementes in der Schließstellung sicherzustellen. Andererseits dient das Stabilisierungselement zur Unterstützung der Schließbewegung. Bei herkömmlichen Rolltoren ist das Stabilisierungselement in Form einer am unteren Rand des bahnförmigen Behangs befestigten Stange verwirklicht.When using roller doors with a closing element in the form of a web-shaped curtain, a stabilizing element is usually provided at the lower edge of the web-shaped curtain. With this stabilizing element, on the one hand, the shape of the lower edge of the web-shaped curtain is stabilized so as to ensure a defined closure of the closing element in the closed position. On the other hand, the stabilizing element serves to support the closing movement. In conventional roller doors, the stabilizing element is realized in the form of a bar attached to the lower edge of the web-shaped hanging.

Wie eingangs bereits erläutert, werden Rolltore mit einem Schließelement in Form eines bahnförmigen Behangs insbesondere dann eingesetzt, wenn es auf schnelle Öffnungs- und Schließbewegungen ankommt. In diesem Fall entsteht durch die Anbringung des Stabilisierungselementes am unteren Rand des bahnförmigen Behangs im Verlauf der Schließbewegung ein beachtliches Verletzungsrisiko, wenn das Stabilisierungselement im Verlauf der Schließbewegung auf eine in der Einfahrt stehende Person auftrifft. Ferner können durch die Stabilisierungselemente herkömmlicher Rolltore im Verlauf der Schließbewegung auch Gegenstände beschädigt werden. Schließlich können beim Einsatz herkömmlicher Stabilisierungselemente auch Beschädigungen des Behangs selbst und/oder der zur Führung der Bewegung des Behangs benutzten Führungselemente auftreten, wenn ein Fahrzeug auf den Behang in der Schließstellung auftrifft.As already explained, roller doors are used with a closing element in the form of a web-shaped curtain especially when it comes to fast opening and closing movements. In this case, the attachment of the stabilizing element at the lower edge of the web-shaped curtain in the course of the closing movement a considerable risk of injury when the stabilizing element impinges in the course of the closing movement on a person standing in the entrance. Furthermore, objects can be damaged by the stabilizing elements of conventional roller doors in the course of the closing movement. Finally, when using conventional stabilizing elements, damage to the curtain itself and / or the guide elements used to guide the movement of the curtain can occur when a vehicle strikes the curtain in the closed position.

Angesichts dieser Probleme bei herkömmlichen Rolltoren wurde bereits vorgeschlagen, das üblicherweise in Form einer starren Stange verwirklichte Stabilisierungselement durch in eine durch Umfalten des unteren Randes des Behangs auf sich selbst gebildete Schlaufe eingefüllten Sand zu ersetzen. Durch diese Sandfüllung des unteren Randes des Behangs wird einerseits die Auslösung der Schließbewegung unterstützt und andererseits werden aufgrund der Nachgiebigkeit der Sandfüllung Verletzungen und Beschädigungen im Verlauf der Schließbewegung verhindert. Ferner können durch diese Sandfüllung auch Beschädigungen des Behangs und/oder der Führungselemente verhindert werden, wenn ein Gegenstand in der Schließstellung des Behangs auf den selben auftrifft. Allerdings wird bei dieser Weiterbildung herkömmlicher Rolltore die dem Stabilisierungselement ursprünglich zugedachte Funktion, nämlich die Sicherstellung einer vorgegebenen Form des unteren Randes des bahnförmigen Behangs, nicht mehr erfüllt.In view of these problems with conventional roller shutter doors, it has already been proposed to replace the stabilizing element, which is usually realized in the form of a rigid rod, by sand filled into a loop formed by folding the lower edge of the curtain on itself. By this sand filling of the lower edge of the curtain on the one hand, the triggering of the closing movement is supported and on the other hand injuries and damage in the course of the closing movement are prevented due to the flexibility of the sand filling. Furthermore, damage to the curtain and / or the guide elements can be prevented by this sand filling, if an object in the closed position of the curtain hits the same. However, in this development of conventional roller doors that the original stabilizing element intended function, namely the assurance of a predetermined shape of the lower edge of the web-shaped curtain, no longer satisfied.

Angesichts dieser Probleme im Stand der Technik wird in der DE-U-202 04 637 eine Weiterbildung bekannter Rolltore angegeben, die im wesentlichen dadurch gekennzeichnet ist, daß das Stabilisierungselement elastisch verformbar ist. Durch eine solche Ausführung des Stabilisierungselementes wird einerseits eine Nachgiebigkeit des Stabilisierungselementes beim Auftreffen auf Gegenstände oder Personen erreicht und andererseits eine Rückstellung des Stabilisierungselementes und damit auch des unteren Randes des Schließelementes in eine vorgegebene Form sichergestellt. Insgesamt wird so die Gefahr von Beschädigungen oder Verletzungen von in der Einfahrt befindlichen Gegenständen oder Personen beseitigt und andererseits ein vorgegebener Abschluß in der Schließstellung sichergestellt.In view of these problems in the prior art, DE-U-202 04 637 discloses a further development of known rolling doors, which is essentially characterized in that the stabilizing element is elastically deformable. By such an embodiment of the stabilizing element on the one hand a yielding of the stabilizing element when hitting objects or persons is achieved and on the other hand ensures a provision of the stabilizing element and thus also the lower edge of the closing element in a predetermined shape. Overall, this eliminates the risk of damage or injury to objects or persons in the driveway and, on the other hand, ensures a predetermined closure in the closed position.

Als besonders zweckmäßig wird es bei den bekannten Rolltoren angesehen, wenn das Stabilisierungselement ein Federelement, insbesondere ein eine parallel zum unteren Rand des bahnförmigen Behangs verlaufende Wendelachse wendelförmig umlaufendes Federelement aufweist. Dabei kann der Erhalt einer vorgegebenen Form des unteren Randes besonders zuverlässig gewährleistet werden, wenn das Federelement zur Vergrößerung der Rückstellkraft bei einer Verformung vorgespannt ist. Die Gefahr von Beschädigungen oder Verletzungen kann weiter reduziert werden, wenn das beispielsweise in Form eines Federelementes verwirklichte Stabilisierungselement zumindest abschnittweise von einer Schicht aus nachgiebigem Material umgeben ist. Das Stabilisierungselement des aus der genannten Schrift bekannten Rolltors kann in einer am unteren Rand des bahnförmigen Behangs gebildeten Schlaufe aufgenommen sein, wobei es sich konstruktiv als besonders zweckmäßig erwiesen hat, wenn der untere Rand des bahnförmigen Behangs zur Bildung der Schlaufe auf sich selbst zurückgefaltet ist.Particularly useful it is considered in the known roller shutters, when the stabilizing element has a spring element, in particular a parallel to the lower edge of the web-shaped curtain extending helical axis helically rotating spring element. In this case, the preservation of a predetermined shape of the lower edge can be ensured particularly reliable when the spring element is biased to increase the restoring force at a deformation. The risk of damage or injury can be further reduced if the stabilizing element realized, for example, in the form of a spring element is at least partially surrounded by a layer of resilient material. The stabilizing element of the rolling door known from the cited document can be received in a loop formed at the lower edge of the web-shaped curtain, wherein it has proven to be particularly constructive when the lower edge of the web-shaped curtain is folded back on itself to form the loop.

Zur Erhöhung der Betriebszuverlässigkeit der bekannten Vorrichtungen kann an mindestens einem seitlichen Rand des Schließelementes mindestens ein mit dem Führungselement zusammenwirkendes Führungsglied angeordnet sein. Falls durch Aufprall eines Gegenstandes bzw. Fahrzeuges auf das Schließelement in der Schließstellung das Führungsglied aus dem Führungselement gelöst wird, kann eine zuverlässige Führung der Bewegung des Schließelementes sichergestellt werden, wenn am oberen Rand des Führungselementes eine Einlaufanordnung angeordnet ist, mit der das Führungsglied bei einer Schließbewegung des Schließelementes automatisch in das Führungselement einführbar ist.To increase the operational reliability of the known devices, at least one guide element cooperating with the guide element can be arranged on at least one lateral edge of the closing element. If the guide member is released from the guide element by impact of an object or vehicle on the closing element in the closed position, a reliable guidance of the movement of the closing element can be ensured if an inlet arrangement is arranged at the upper edge of the guide element, with which the guide member at a Closing movement of the closing element is automatically inserted into the guide element.

Ferner sind in der EP-A-0,143,712 Rolltore nach dem Oberbegriff des Patentanspruchs 1 angegeben.Furthermore, in EP-A-0,143,712 rolling doors according to the preamble of claim 1 are given.

Durch Einsatz elastisch verformbarer Stabilisierungselemente am unteren Rand der Schließelemente bekannter Rolltore können Beschädigungen oder Verletzungen von in der Einfahrt befindlichen Gegenständen oder Personen weitgehend ausgeschlossen werden. Allerdings hat es sich gezeigt, daß mit diesen im Hinblick auf die Reduzierung von Verletzungen oder Beschädigungen vorteilhaften Stabilisierungselementen nur eine unzureichende Stabilisierung des Schließelementes in der Schließstellung bei Windlasten und dgl. erreichbar ist. Angesichts dieser Probleme im Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Rolltor bereitzustellen, mit dem einerseits Beschädigungen oder Verletzungen von in der Einfahrt befindlichen Gegenständen oder Personen weitgehend ausgeschlossen werden können und andererseits auch noch eine hinreichende Stabilität des Schließelementes in der Schließstellung erreichbar istBy using elastically deformable stabilizing elements on the lower edge of the closing elements of known rolling doors, damage or injury to objects or persons located in the driveway can be largely ruled out. However, it has been shown that with these in view of reducing injury or damage advantageous stabilizing elements only insufficient stabilization of the closing element in the closed position at wind loads and the like. Can be reached. In view of these problems in the prior art, the present invention seeks to provide a roller door, with the one hand damage or injury of objects or persons located in the entrance can be largely excluded and on the other hand, a sufficient stability of the closing element in the closed position can be reached

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebene Weiterbildung bekannter Rolltore gelöst. Bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Patentansprüchen angegeben.According to the invention this object is achieved by the specified in the characterizing part of claim 1 further known roller doors. Preferred embodiments of the invention are indicated in the dependent claims.

Durch die geringe Rückstellkraft bei Verformung in einer der Schließrichtung entgegengesetzten Richtung wird eine zufriedenstellende Reduzierung der Gefahr von Beschädigungen oder Verletzungen erreicht, während durch die höhere Rückstellkraft in einer quer dazu verlaufenden Richtung eine gute Stabilisierungsfunktion in dieser Richtung sichergestellt wird.Due to the low restoring force when deformed in a direction opposite to the closing direction, a satisfactory reduction in the risk of damage or injury is achieved, while a good stabilizing function in this direction is ensured by the higher restoring force in a direction transverse thereto.

Zum Erhalt unterschiedlicher Rückstellkräfte kann das Stabilisierungselement mindestens ein Federelement mit unsymmetrischem, insbes. ovalem, elliptischem oder rechteckigem Querschnitt in einer senkrecht zum unteren Rand des Schließelementes verlaufenden Schnittebene aufweisen, wobei das Federelement in einer senkrecht zum Schließelement in der Schließstellung verlaufenden Richtung eine größere Dicke aufweist, als in einer in Schließrichtung verlaufenden Richtung. Zusätzlich oder alternativ kann das Stabilisierungselement mindestens zwei in einer senkrecht zum Schließelement in der Schließrichtung verlaufenden Richtung nebeneinander angeordnete Federelemente aufweisen, um so eine besonders hohe Rückstellkraft in dieser Richtung zu erreichen.To obtain different restoring forces, the stabilizing element may have at least one spring element with asymmetrical, esp. Oval, elliptical or rectangular cross-section in a perpendicular to the lower edge of the closing element extending cutting plane, wherein the spring element has a greater thickness in a direction perpendicular to the closing element in the closed position direction , as in a direction extending in the closing direction. Additionally or alternatively, the stabilizing element can be at least two in a direction perpendicular to the closing element in the closing direction extending direction juxtaposed spring elements, so as to achieve a particularly high restoring force in this direction.

Ein elastisch verformbares Stabilisierungselement kann konstruktiv besonders einfach in Form eines Federstabs verwirklicht werden.An elastically deformable stabilizing element can be realized structurally particularly simple in the form of a spring bar.

Im Rahmen der Erfindung hat es sich allerdings als besonders zweckmäßig herausgestellt, wenn das Stabilisierungselement zumindest teilweise aus einem Elastomermaterial und/oder Kunststoff besteht. Durch geschickte Wahl der Querschnittsform des aus einem Elastomermaterial gebildeten Stabilisierungselementes können die unterschiedlichen Rückstellkräfte in einer der Schließrichtung entgegengesetzten Richtung einerseits und in einer quer dazu verlaufenden Richtung andererseits besonders einfach eingestellt werden.In the context of the invention, however, it has proved to be particularly expedient if the stabilizing element consists at least partially of an elastomeric material and / or plastic. By skillful choice of the cross-sectional shape of the stabilizing element formed of an elastomeric material, the different restoring forces in a direction opposite to the closing direction on the one hand and in a direction transverse thereto on the other hand can be adjusted particularly easily.

Bei Verwendung eines Stabilisierungselementes aus einem Elastomermaterial und/oder einem nachgiebigen Kunststoff wird eine besonders geringe Verletzungsgefahr für Personen erreicht. Ferner wird das Risiko von Beschädigungen von Gütern reduziert. Das gilt im besonderen im Vergleich zu herkömmlichen Metallunterteilen.When using a stabilizing element made of an elastomeric material and / or a flexible plastic, a particularly low risk of injury to persons is achieved. Furthermore, the risk of damage to goods is reduced. This is especially true in comparison to conventional metal parts.

Bei Verwendung von Stabilisierungselementen aus einem Elastomermaterial und/oder Kunststoff können auch optimale Verhältnisse beim Anfahren des Rolltores erreicht werden, da keine Schäden oder Anfahrmarkierungen entstehen können, wie sie beispielsweise bei der Verwendung von Stabilisierungselementen aus Aluminium beobachtet werden.When using stabilizing elements made of an elastomeric material and / or plastic and optimal conditions when starting the rolling door can be achieved because no damage or Anfahrmarkierungen may arise, as observed for example in the use of stabilizing elements made of aluminum.

Gemäß der Erfindung weist das Stabilisierungselement zum Erhalt unterschiedlicher Rückstellkräfte auch mindestens eine Blattfeder mit senkrecht zur Schließrichtung ausgerichteter Hauptfläche auf. Dabei ist es konstruktiv und aus Sicherheitsgründen besonders bevorzugt, wenn diese Blattfeder in das Elastomermaterial eingebettet ist. Eine besonders hohe Rückstellkraft in einer quer zur Schließrichtung verlaufenden Richtung bei gleichzeitiger Sicherstellung einer hinreichend geringen Rückstellkraft in einer der Schließrichtung entgegengesetzten Richtung kann erreicht werden, wenn mindestens zwei mit Abstand voneinander parallel zueinander angeordnete Blattfedern vorgesehen sind, welche zweckmäßigerweise beide in ein Elastomermaterial eingebettet sind.According to the invention, the stabilizing element to obtain different restoring forces and at least one leaf spring with perpendicular to the closing direction aligned main surface. It is constructive and for safety reasons particularly preferred when this leaf spring is embedded in the elastomeric material. A particularly high restoring force in a direction transverse to the closing direction while ensuring a sufficiently low restoring force in a direction opposite to the closing direction can be achieved if at least two spaced apart from each other parallel leaf springs are provided, which are expediently both embedded in an elastomeric material.

Zusätzlich oder alternativ können in das Stabilisierungselement auch Verstärkungsdrähte, wie sie bei der Herstellung von Zahnriemen zum Einsatz kommen, Verstärkungsgurte oder dgl. eingearbeitet sein.Additionally or alternatively, reinforcement wires or the like may also be incorporated into the stabilizing element, as used in the production of toothed belts.

Das bei dem erfindungsgemäßen Rolltor eingesetzte Stabilisierungselement kann besonders einfach an dem Schließelement befestigt werden, wenn das Stabilisierungselement eine an seinem oberen Rand angeordnete und sich in Längsrichtung des Stabilisierungselementes erstreckende Nut aufweist, in der ein unterer Rand des Behangs zumindest abschnittweise aufgenommen ist. Dabei kann der untere Rand des Behangs in die Nut eingeklebt und/oder eingeschraubt sein, um so eine besonders zuverlässige Befestigung des Stabilisierungselementes am unteren Rand des Behangs zu erreichen.The stabilizing element used in the roller shutter according to the invention can be particularly easily attached to the closing element, when the stabilizing element has a groove arranged at its upper edge and extending in the longitudinal direction of the stabilizing element, in which a lower edge of the curtain is at least partially included. In this case, the lower edge of the curtain can be glued into the groove and / or screwed so as to achieve a particularly reliable attachment of the stabilizing element at the bottom of the curtain.

Bei erfindungsgemäßen Rolltoren wird die Gefahr von Verletzungen und/oder Beschädigungen von in der Einfahrt befindlichen Gegenständen oder Personen und das Risiko der Beschädigung des Rolltors selbst durch Bereitstellung eines elastisch verformbaren Stabilisierungselementes reduziert. Eine weitere Reduktion der Beschädigungs- und/oder Verletzungsgefahr kann erreicht werden, wenn dem Schließelement eine zum Abschalten und/oder Veranlassen einer Richtungsumkehr einer an das Schließelement gekoppelten Antriebseinrichtung betreibbare Sicherungseinrichtung zugeordnet ist, damit Überlastungen der Antriebseinrichtung und anhaltende Kraftbeaufschlagungen von in der Einfahrt befindlichen Gegenständen oder Personen zuverlässig ausgeschlossen werden.In rolling doors according to the invention the risk of injury and / or damage of objects or persons located in the driveway and the risk of damaging the roller shutter itself is reduced by providing an elastically deformable stabilizing element. A further reduction of the risk of damage and / or injury can be achieved if the closing element is associated with a safety device operable to switch off and / or cause reversal of a drive device coupled to the closing element, thereby overloading the drive device and sustained application of force to objects located in the entrance or persons are reliably excluded.

Bei einer besonders bevorzugten Ausführungsform der Erfindung weist die Sicherungseinrichtung ein zum Abgeben drahtlos übertragbarer Signale betreibbares Sendeelement und ein zum Empfangen der drahtlos übertragenen Signale betreibbares Empfangselement auf, wobei das Sendeelement und/oder das Empfangselement vorzugsweise in einem das Stabilisierungselement durchsetzenden Kanal angeordnet ist. Bei einer bevorzugten Ausführungsform der Erfindung ist der zur Aufnahme der Sicherungseinrichtung dienende Kanal im Bereich des unteren Randes des Stabilisierungselementes vorgesehen. Zusätzlich oder alternativ kann der Kanal für die Sicherungseinrichtung aber auch mittig oder am oberen Rand des Stabilisierungselementes angeordnet sein. Eine Anordnung im Bereich des oberen Randes des Stabilisierungselementes ist dann bevorzugt, wenn die Gefahr besteht, daß das Stabilisierungselement in der Schließstellung des Rolltores Bodenfeuchtigkeit ausgesetzt ist.In a particularly preferred embodiment of the invention, the securing device has a transmitting element operable for delivering wirelessly transferrable signals and a receiving element operable to receive the wirelessly transmitted signals, wherein the transmitting element and / or the receiving element is preferably arranged in a channel passing through the stabilizing element. In a preferred embodiment of the invention, the serving for receiving the securing device channel is provided in the region of the lower edge of the stabilizing element. Additionally or alternatively, however, the channel for the securing device can also be arranged centrally or at the upper edge of the stabilization element. An arrangement in the region of the upper edge of the stabilizing element is preferred when there is a risk that the stabilizing element is exposed to soil moisture in the closed position of the roll-up door.

Im Rahmen der Erfindung hat es sich als zweckmäßig erwiesen, wenn das Stabilisierungselement mehrteilig ausgeführt ist, wobei vorzugsweise mindestens eines der Stabilisierungselementteile von einem zur Unterbringung einer Sicherungseinrichtung dienenden Kanal durchsetzt ist. Dieses Stabilisierungselementteil kann "einklipsbar" unterhalb des Profils ausgeführt sein, damit bei Beschädigung des Kanals ein kostengünstiges Auswechseln des entsprechenden Stabilisierungselementteils möglich ist.In the context of the invention, it has proven to be expedient if the stabilizing element is designed in several parts, wherein preferably at least one of the stabilizing element parts is penetrated by a serving to accommodate a security device channel. This stabilizing element part can be "clipped" carried out below the profile, so that when damage to the channel cost-effective replacement of the corresponding stabilizing element part is possible.

Im Rahmen der Erfindung ist auch daran gedacht, an dem Stabilisierungselement eine Aufnahme anzuordnen, welche die Festlegung handelsüblicher Sicherungseinrichtungen bzw. Kontaktschienen ermöglicht. Bei allen Ausführungsformen der Erfindung, welche mit einem zur Aufnahme einer Sicherungseinrichtung dienenden Kanal im Stabilisierungselement ausgeführt sind, kann eine Verformung des Stabilisierungselementes im Bereich des Kanals zur Unterbrechung des Übertragungsweges drahtlos übertragener Signale vom Sendeelement der Sicherungseinrichtung zum Empfangselement der Sicherungseinrichtung ausgenutzt werden, so daß diese Unterbrechung als Anlaß für die Abschaltung oder die Richtungsumkehr der Antriebseinrichtung genutzt werden kann. Bei einer besonders bevorzugten Ausführungsform der Erfindung weist die Sicherungseinrichtung eine Lichtschranke mit einem in den Kanal des Stabilisierungselementes eingesetzten Sendeelement und einem ebenfalls in den Kanal des Stabilisierungselementes eingesetzten Empfangselement auf. Bei dieser besonders bevorzugten Ausführungsform der Erfindung kann durch das Stabilisierungselement einerseits die Signalübertragungsstrecke unterbrochen werden. Andererseits bewirkt das das Empfangselement und das Sendeelement aufnehmende Stabilisierungselement auch noch einen zuverlässigen Schutz der Sicherungseinrichtung gegen Beschädigungen.In the context of the invention is also thought to arrange a receptacle on the stabilizing element, which allows the definition of commercially available security devices or contact rails. In all embodiments of the invention, which are designed with a serving for receiving a security device channel in the stabilizing element, a deformation of the stabilizing element in the region of the channel for interrupting the transmission path of wirelessly transmitted signals from the transmitting element of the securing device to the receiving element of the securing device can be exploited, so that these Interruption can be used as a reason for the shutdown or the direction reversal of the drive device. In a particularly preferred embodiment of the invention, the securing device has a light barrier with a transmitting element inserted into the channel of the stabilizing element and a receiving element likewise inserted into the channel of the stabilizing element. In this particularly preferred embodiment of the invention, on the one hand, the signal transmission path can be interrupted by the stabilizing element. On the other hand, the stabilizing element accommodating the receiving element and the transmitting element also effects a reliable protection of the securing device against damage.

Bei einer mehrteiligen Ausführung des Stabilisierungselementes kann das Stabilisierungselement auch Aufnahmen zur Festlegung von Dichtlippen oder Dichtprofilen aufweisen, die ggf. besonders einfach in diese Aufnahmen eingeklipst werden. Diese Ausführungsform ist von Interesse, wenn große Bodenunebenheiten auszugleichen sind. Zusätzlich oder alternativ zu einklipsbaren Dichtlippen oder Dichtprofilen ist auch an die Anordnung von Befestigungsstegen an einem der Stabilisierungselementteile gedacht, auf die entsprechende Dichtlippen oder Dichtprofile aufgeschoben werden können.In a multi-part design of the stabilizing element, the stabilizing element may also have recordings for fixing of sealing lips or sealing profiles, which may possibly be clipped particularly easily into these receptacles. This embodiment is of interest when large bumps are to be compensated. Additionally or alternatively to be clipped sealing lips or sealing profiles is also thought of the arrangement of fastening webs on one of the stabilizing element parts can be pushed onto the corresponding sealing lips or sealing profiles.

Als zusätzlicher Vorteil einer mehrteiligen Ausführung des Stabilisierungselementes ist hervorzuheben, daß eine solche Ausführung eine besonders geringe Höhe des Stabilisierungselementes erlaubt. Dann ist nur noch ein geringer Sturzbedarf des Tores erforderlich. Ferner ermöglicht die mehrteilige Ausführung des Stabilisierungselementes auch eine kostengünstige und einfache Herstellung von Rolltoren.As an additional advantage of a multi-part design of the stabilizing element is to emphasize that such a design a particularly low height of the stabilizing element allowed. Then only a small fall requirement of the gate is required. Furthermore, the multi-part design of the stabilizing element also allows a cost-effective and simple production of roller doors.

Bei herkömmlichen Rolltoren wird die Bewegung des bahnförmigen Behangs üblicherweise mit Hilfe von an dem seitlichen Rand des Schließelementes angeordneten Führungselementen in Form von Führungsschienen geführt. In diese Führungsschienen greift der im Verlauf der Schließbewegung von dem Wickel abgerollte untere Rand des bahnförmigen Behangs ein. Anschließend wird die Schließbewegung mit Hilfe der in den Führungsschienen aufgenommenen seitlichen Ränder des Behangs geführt. Zur zuverlässigen Einführung des unteren Randes des Behangs in die Führungsschiene ist üblicherweise am oberen Rand des Führungselementes eine Einlaufanordnung angeordnet, mit der der seitliche Rand des Schließelementes bei einer Schließbewegung automatisch in das Führungselement einführbar ist. Bei herkömmlichen Rolltoren ist diese Einlaufanordnung durch trichterförmige Erweiterungen am oberen Rand der Führungsschienen verwirklicht. Es hat sich jedoch gezeigt, daß es insbesondere bei schnell laufenden Rolltoren mit am unteren Rand des Behangs angeordneten Stabilisierungselementen in einigen Fällen trotz Einsatz der bekannten Einlaufanordnungen zu Fehlfunktionen kommt, bei denen der Behang nicht in der gewünschten Form in die Führungsschienen eingeführt wird.In conventional roller doors, the movement of the web-shaped curtain is usually performed by means of arranged on the lateral edge of the closing element guide elements in the form of guide rails. In this guide rails engages in the course of the closing movement of the winding unrolled lower edge of the web-shaped curtain. Subsequently, the closing movement is performed using the recorded in the guide rails lateral edges of the curtain. For reliable introduction of the lower edge of the curtain in the guide rail usually an inlet arrangement is arranged at the upper edge of the guide element, with which the lateral edge of the closing element is automatically inserted in a closing movement in the guide element. In conventional roller doors this inlet arrangement is realized by funnel-shaped extensions on the upper edge of the guide rails. However, it has been shown that, in particular in the case of high-speed roll-up doors with stabilizing elements arranged at the lower edge of the curtain, in some cases, despite the use of the known inlet arrangements, malfunctions occur in which the curtain is not introduced into the guide rails in the desired form.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung wird dieses Problem durch eine Weiterbildung bekannter Rolltore gelöst, welche im wesentlichen dadurch gekennzeichnet ist, daß die Einlaufanordnung am oberen Rand der Führungselemente mindestens zwei an einander entgegengesetzte Begrenzungsflächen des Schließelementes und/oder eines am unteren Rand davon angeordneten Stabilisierungselementes anlegbare Vorspanneinrichtungen aufweist, mit denen das Schließelement bzw. das Stabilisierungselement in einander entgegengesetzte und quer zur Bewegungsrichtung des Schließelementes verlaufende Richtungen gedrängt wird.According to a particularly preferred embodiment of the invention, this problem is solved by a development known roller doors, which is characterized essentially in that the inlet arrangement at the top of the guide elements at least two mutually opposite boundary surfaces of the closing element and / or arranged at the bottom of it stabilizing element has applyable biasing means with which the closing element or the stabilizing element is urged in opposite directions and transverse to the direction of movement of the closing element extending directions.

Durch derartige Einlaufanordnungen wird eine Zentrierung des unteren Randes des Schließelementes erreicht. Diese Zentrierung ist dynamisch ausgelegt, so daß bei unerwünscht hohen Auslenkungen in der einen oder anderen Richtung entsprechend hohe Rückstellkräfte durch die dann beaufschlagten Vorspanneinrichtungen erzeugt werden. Mit dieser dynamischen Auslegung der Einlaufanordnung kann eine zuverlässige Einführung des unteren Randes der Schließelemente in die Führungselemente selbst bei hohen Schließgeschwindigkeiten sichergestellt werden. Bei einer besonders bevorzugten Ausführungsform der Erfindung weist mindestens eine Vorspanneinrichtung mindestens ein im unbelasteten Zustand sich etwa senkrecht zum Schließelement in der Schließstellung erstreckendes und durch das darauf auflaufende Schließelement bzw. Stabilisierungselement elastisch auslenkbares Borstenelement auf, wobei durch die Auslenkung des Borstenelementes eine quer zur Schließrichtung bzw. Bewegungsrichtung des Schließelementes gerichtete und auf das Schließelement bzw. Stabilisierungselement einwirkende Vorspannkraft erzeugt wird.By such Einlaufanordnungen a centering of the lower edge of the closing element is achieved. This centering is designed dynamically, so that in undesirable high deflections in one or the other direction correspondingly high restoring forces are generated by the then biased biasing devices. With this dynamic design of the inlet arrangement can be a reliable introduction of the lower edge of the closing elements in the guide elements even at high Closing speeds are ensured. In a particularly preferred embodiment of the invention, at least one pretensioning device has at least one bristle element elastically deflectable in the unloaded state approximately perpendicular to the closing element in the closed position and elastically deflectable by the closing element or stabilizing element resting thereon, wherein the deflection of the bristle element results in a transverse direction to the closing direction Direction of movement of the closing element directed and acting on the closing element or stabilizing element biasing force is generated.

Durch entsprechende Anordnung der mindestens einen in dem Stabilisierungselement eingebetteten Blattfeder wird erreicht, daß das Stabilisierungselement beim Anfahren aus der Öffnungsstellung um ca. 90° umkippt und dann ohne Beschädigungen aus den Führungen gedrückt wird. Bei Winddruck bleibt das Stabilisierungselement stabil in den seitlichen Führungsschienen des Rolltores.By appropriate arrangement of the at least one embedded in the stabilizing element leaf spring is achieved that the stabilizing element tilts when approaching from the open position by about 90 ° and is then pressed out of the guides without damage. At wind pressure, the stabilization element remains stable in the lateral guide rails of the roll-up door.

Nachstehend wird die Erfindung unter Bezugnahme auf die Zeichnung, auf die hinsichtlich aller erfindungswesentlichen und in der Beschreibung nicht näher herausgestellten Einzelheiten ausdrücklich verwiesen wird, erläutert. In der Zeichnung zeigt:

The invention will be explained with reference to the drawing, to which reference is expressly made with respect to all essential to the invention and in the description unspecified highlighted details. In the drawing shows:
Fig. 1
a first schematic sectional view of a rolling door according to the invention and
Fig. 2
a second schematic sectional view of a roller shutter according to the invention.

Das in Fig. 1 dargestellte Rolltor umfaßt einen bahnförmigen Behang 10, an dessen unterem Rand ein Stabilisierungselement 20 angeordnet ist. Das Stabilisierungselement 20 weist an seinem oberen Rand eine Nut 22-auf, in der der untere Rand des Behangs 10 aufgenommen ist. Zur sicheren Befestigung des Stabilisierungselementes 20 am unteren Rand des Behangs 10 kann der Behang 10 in die Nut 22 eingeklebt und/oder eingeschraubt sein. Das Stabilisierungselement 20 weist insgesamt in einer senkrecht zu der durch den Pfeil P angedeuteten Schließrichtung des Behangs 10 verlaufenden Richtung eine geringere Dicke auf als in der Schließrichtung selbst. Das Stabilisierungselement 20 ist dabei insgesamt im wesentlichen aus einem Elastomermaterial gebildet. Die einer Verformung des Stabilisierungselementes 20 in einer der Schließrichtung entgegengesetzten Richtung entgegenwirkende Rückstellkraft ist bei der in der Zeichnung dargestellten Ausführungsform der Erfindung kleiner als die einer Verformung des Stabilisierungselementes in einer quer dazu, insbesondere etwa senkrecht zum Schließelement in der Schließstellung, verlaufenden Richtung entgegenwirkende Rückstellkraft. Diese Eigenschaft des Stabilisierungselementes 20 wird dadurch erreicht, daß in das im wesentlichen aus einem Elastomermaterial gebildete Stabilisierungselement 20 zwei Blattfedern 24 eingebettet sind, deren Hauptflächen etwa senkrecht zur Schließrichtung P verlaufen, um so eine besonders geringe Rückstellkraft bei einer Verformung in einer der Schließrichtung entgegengesetzten Richtung sicherzustellen und eine besonders hohe Rückstellkraft bei einer Verformung des Stabilisierungselementes in einer senkrecht zur Schließrichtung verlaufenden Richtung zu bewirken. Die Blattfedern 24 sind in dem Stabilisierungselement 20 etwa parallel zueinander und mit Abstand voneinander eingebettet, um so unter Gewährleistung einer hohen Rückstellkraft in einer senkrecht zur Schließrichtung verlaufenden Richtung eine vergleichsweise geringe Rückstellkraft bei einer Verformung in einer der Schließrichtung entgegengesetzten Richtung sicherzustellen.The roller door shown in Fig. 1 comprises a web-shaped curtain 10, at the lower edge of a stabilizing element 20 is arranged. The stabilizing element 20 has at its upper edge a groove 22 in which the lower edge of the curtain 10 is received. For secure attachment of the stabilizing element 20 at the bottom of the curtain 10, the curtain 10 can be glued into the groove 22 and / or screwed. Overall, the stabilizing element 20 has a smaller thickness in a direction perpendicular to the direction indicated by the arrow P closing direction of the curtain 10 direction than in the closing direction itself. The stabilizing element 20 is formed substantially entirely of an elastomeric material. The counteracting a deformation of the stabilizing element 20 in a direction opposite to the closing direction Restoring force is smaller in the embodiment of the invention shown in the drawing than a deformation of the stabilizing element in a transverse thereto, in particular approximately perpendicular to the closing element in the closed position, extending direction counteracting restoring force. This property of the stabilizing element 20 is achieved in that in the substantially formed from an elastomeric material stabilizer element 20 two leaf springs 24 are embedded whose main surfaces are approximately perpendicular to the closing direction P, so a particularly low restoring force at a deformation in the opposite direction of the closing direction ensure and cause a particularly high restoring force at a deformation of the stabilizing element in a direction perpendicular to the closing direction. The leaf springs 24 are embedded in the stabilizing element 20 approximately parallel to each other and at a distance from each other, so as to ensure a comparatively low restoring force at a deformation in a direction opposite to the closing direction while ensuring a high restoring force in a direction perpendicular to the closing direction.

An seinem unteren Rand ist das in Fig. 1 dargestellte Stabilisierungselement 20 von einem in Längsrichtung des Stabilisierungselementes verlaufenden Kanal 26 durchsetzt. Dieser Kanal 26 dient zur Aufnahme einer beispielsweise in Form einer Lichtschranke verwirklichten Sicherungseinrichtung, mit der bei einer Verformung der den Kanal 26 begrenzenden Mantelfläche des Stabilisierungselementes 20 die Abschaltung oder Richtungsumkehr einer an das Schließelement gekoppelten Antriebseinrichtung ausgelöst wird.At its lower edge, the stabilizing element 20 shown in FIG. 1 is penetrated by a channel 26 extending in the longitudinal direction of the stabilizing element. This channel 26 serves to accommodate a realized in the form of a light barrier device, for example, with the deformation of the channel 26 delimiting lateral surface of the stabilizing element 20, the shutdown or reversal of direction coupled to the closing element drive device is triggered.

Im Rahmen der Erfindung ist auch daran gedacht, den zur Aufnahme der Sicherungseinrichtung dienenden Kanal mittig oder am oberen Rand des Stabilisierungselementes anzuordnen, wie in Fig. 1 bei 26 bzw. 26" angedeutet.In the context of the invention, it is also intended to arrange the channel for receiving the securing means centrally or at the upper edge of the stabilizing element, as indicated in Fig. 1 at 26 and 26 ".

Schließlich weist das in Fig. 1 dargestellte Stabilisierungselement auch noch eine nach vorne und unten abragende Dichtlippe 28 auf, welche bei Erreichen der Schließstellung in dichtende Anlage an den Boden des mit dem Schließelement zu verschließenden Raumes gelangt.Finally, the stabilizing element shown in FIG. 1 also has a sealing lip 28 protruding forwards and downwards, which, upon reaching the closed position, comes into sealing engagement with the bottom of the space to be closed by the closing element.

Diese Dichtlippe kann auch als separates Stabilisierungselementteil ausgeführt sein, welches in eine entsprechende Aufnahme einklipsbar und/oder auf einen entsprechenden Befestigungssteg aufschiebbar ist.This sealing lip can also be designed as a separate stabilizing element part, which can be clipped into a corresponding receptacle and / or pushed onto a corresponding fastening web.

In Fig. 2 ist schematisch eine Einlaufanordnung 30 für das anhand der Fig. 1 erläuterte Rolltor gezeigt. Mit der Einlaufanordnung 30 wird der untere Rand des Schließelementes bei einer Schließbewegung automatisch in eine am seitlichen Rand der mit dem Schließelement zu verschließenden Öffnung angeordnete Führungsschiene 40 eingefädelt. Dazu weist die Einlaufanordnung 30 zwei aufeinander entgegengesetzten Seiten des Schließelementes angeordnete Trägerelemente 32 und 34 auf. Von diesen Trägerelementen 32 und 34 ausgehend erstreckt sich eine Vielzahl von Vorspannelementen in Richtung auf den Behang bzw. das Stabilisierungselement 20. Bei Auftreffen des Stabilisierungselementes 20 auf die Borsten 33 bzw. 35 werden die Borsten ausgelenkt. Dadurch wird eine das Stabilisierungselement 20 beaufschlagende und quer dazu ausgerichtete Rückstellkraft bewirkt. Durch die von den Borsten 33 auf das Stabilisierungselement 20 ausgeübte Rückstellkraft wird das Stabilisierungselement 20 in Fig. 2 nach links gedrängt, während es durch die von den Borsten 35 darauf ausgeübte Rückstellkraft in der Zeichnung nach rechts gedrängt wird. Insgesamt wird durch die Rückstellkräfte der Borsten 33 und 35 eine Zentrierung des Stabilisierungselementes 20 bewirkt. Durch diese Zentrierung wird das Stabilisierungselement 20 zuverlässig in den oberen Rand der Führungsschiene 40 eingefädelt.In Fig. 2, an inlet arrangement 30 is schematically shown for the explained with reference to FIG. 1 roller shutter. With the inlet arrangement 30, the lower edge of the closing element is automatically threaded during a closing movement into a guide rail 40 arranged at the lateral edge of the opening to be closed by the closing element. For this purpose, the inlet arrangement 30 has two mutually opposite sides of the closing element arranged support members 32 and 34. Starting from these support elements 32 and 34, a plurality of biasing elements extends in the direction of the curtain or the stabilization element 20. When the stabilization element 20 strikes the bristles 33 or 35, the bristles are deflected. As a result, a stabilizing element 20 acting and transversely aligned restoring force is effected. By the restoring force exerted by the bristles 33 on the stabilizing element 20, the stabilizing element 20 is urged to the left in Fig. 2, while it is urged to the right by the force exerted by the bristles 35 restoring force in the drawing. Overall, a centering of the stabilizing element 20 is effected by the restoring forces of the bristles 33 and 35. As a result of this centering, the stabilization element 20 is reliably threaded into the upper edge of the guide rail 40.

Die Erfindung ist nicht auf die anhand der Zeichnung erläuterten Ausführungsbeispiele beschränkt. Vielmehr ist auch daran gedacht, die Vorspanneinrichtung anders als durch Borstenelemente zu verwirklichen. Ferner kann das Stabilisierungselement auch mit weniger oder mehr als zwei Blattfedern ausgestattet werden.The invention is not limited to the embodiments explained with reference to the drawing. Rather, it is also thought to realize the biasing device other than by bristle elements. Furthermore, the stabilizing element can also be equipped with fewer or more than two leaf springs.
