Description

Die Erfindung betrifft ein Rolltor mit seitlichen Führungsschienen und einem vorzugsweise handbetätigten Torblatt, welches in den Führungsschienen zwischen einer Öffnungs- und einer Schließstellung geführt ist, wobei zwischen dem Abschlußbereich des Torblattes und dem von der Abschlußkante des Torblattes abgewandten Endrandbereich der mit dem Torblatt abzuschließenden Türöffnung oder dergleichen wenigstens eine sich über einen Restweg des Torblattes bei dessen Übergang in die Öffnungslage spannende Fangeinrichtung oder dergleichen angeordnet ist.The invention relates to a roller door with side guide rails and a preferably manually operated door leaf, which is guided in the guide rails between an open and a closed position, wherein between the end area of the door leaf and the end edge region facing away from the end edge of the door leaf or the door opening to be closed with the door leaf the like at least one catching device or the like is arranged over a remaining path of the door leaf during its transition into the open position.

Ein derartiges Rolltor ist beispielsweise aus der EP 0 362 585 B1 vorbekannt. Hierbei handelt es sich um ein Rolltor in grundsätzlich bekannter Ausgestaltung mit Führungsschienen bzw. Führungsprofilen, in welchen die Seitenränder des Torblattes zwischen der Schließlage und der Öffnungslage verschiebbar geführt sind. Solche Torblätter werden in der Regel auf Walzen auf- und abgerollt, sie können aber auch beim Übergang in die Öffnungsstellung in eine andere Position verfahren werden. Insbesondere wenn derartige Rolltore von Hand bestätigt werden sollen, ist man bestrebt, die Torblätter leichtgewichtig auszugestalten, um die für den Bewegungsvorgang erforderliche Kraft klein zu halten. Hier kommen Torblätter aus in Bewegungsrichtung aufeinanderfolgenden Profilen in Betracht, beispielsweise aus Aluminium oder aber auch sog. Behänge aus durchgehenden, entsprechenden flexiblen Folien und dergleichen mehr. Beim Überführen des Torblattes in den Öffnungszustand besteht die Gefahr, daß bei entsprechend hoher Verzögerung am Ende der Torblattbewegung dessen Abschlußbereich, also beispielsweise ein Abschlußprofil oder ein entsprechend kleiner Lattenbereich eines Behanges aufgrund der darin noch vorhandenen Bewegungsenergie über die Rolle hinwegrutscht. Beim schließen unter entsprechender Beschleunigung zu Beginn des Bewegungsvorganges kann die Trägheit des Abschlußbereiches des Torblattes dazu führen, daß sich an der, der zu verschließenden Toröffnung abgewandten Seite eine Schlaufe bildet. Eine schwere Ausbildung des Abschlußbereiches des Torblattes, beispielsweise durch Einlage eines Flacheisens, kann dieses Verhalten nur bedingt beeinflussen und steht der beabsichtigten leichten Ausbildung des Torblattes insgesamt entgegen. Um bei einem derartigen Torblatt hohe Beschleunigungen und Verzögerungen zu ermöglichen, ohne daß sich der Abschlußbereich des Torblattes gegenüber dem anderen Torblattbereich unregelmäßig bewegt, sieht das Rolltor gemäß der EP 0 362 585 B1 eine Fangeinrichtung vor, die aus zumindest einer an einer Führungsschiene befestigten Feder und einer am Endrandbereich des Torblattes angeordneten Rolle besteht, die beim Überführen des Torblattes in die Öffnungsstellung auf die Feder aufläuft, so daß das Torblatt von der Feder in seiner Öffnungsstellung federnd abgefangen wird. Hierbei werden die von dem Torblatt auf die Feder übertragenen Kräfte in die Führungsschiene eingeleitet.Such a roller door is known for example from EP 0 362 585 B1. This is a roller door in a basically known configuration with guide rails or guide profiles, in which the side edges of the door leaf are slidably guided between the closed position and the open position. Such door leaves are usually rolled up and down on rollers, but they can also be moved to a different position when changing to the open position. In particular if such roller doors are to be confirmed by hand, efforts are made to make the door leaves lightweight in order to keep the force required for the movement process small. Here, door leaves made of profiles which follow one another in the direction of movement come into consideration, for example made of aluminum or else so-called curtains made of continuous, corresponding, flexible Foils and the like. When the door leaf is moved into the open state, there is a risk that, with a correspondingly high delay at the end of the door leaf movement, its end region, for example a end profile or a correspondingly small slatted region of a curtain, will slide over the roller due to the kinetic energy still present therein. When closing with appropriate acceleration at the beginning of the movement process, the inertia of the closing area of the door leaf can lead to the formation of a loop on the side facing away from the door opening to be closed. A heavy formation of the end area of the door leaf, for example by inserting a flat iron, can only influence this behavior to a limited extent and is contrary to the intended light formation of the door leaf as a whole. In order to enable high accelerations and decelerations with such a door leaf without the closing area of the door leaf moving irregularly with respect to the other door leaf area, the roller door according to EP 0 362 585 B1 provides a catching device which consists of at least one spring attached to a guide rail and there is a roller arranged at the end edge region of the door leaf, which runs onto the spring when the door leaf is moved into the open position, so that the door leaf is spring-loaded in its open position. The forces transmitted from the door leaf to the spring are introduced into the guide rail.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Rolltor insbesondere für Handbetrieb zu schaffen, bei dem auftretende Kräfte und Drehmomente im wesentlichen nicht in die Führungsschiene eingeleitet werden, wenn das Torblatt in seine Öffnungsstellung überführt wird.Based on this prior art, the invention has for its object to provide a roller door, in particular for manual operation, in which occurring forces and torques are essentially not introduced into the guide rail when the door leaf is transferred to its open position.

Die erfindungsgemäße Lösung dieser Aufgabenstellung sieht vor, daß die als Feder ausgebildete Fangeinrichtung an einer Konsole abgestützt ist, die mittelbar oder unmittelbar am Gebäude befestigt und mit einer Halterung für eine Wickelwelle des Torblattes oder einer Einrichtung für die Anordnung des Torblattes in einer von der Schließstellung abweichenden Position verbunden ist.The solution to this problem according to the invention provides that the catching device designed as a spring is supported on a console which is attached directly or indirectly to the building and with a holder for a winding shaft of the door leaf or a device for arranging the door leaf in a position deviating from the closed position.

Vorteil des erfindungsgemäß ausgestaltenen Rolltores ist, daß die beim Erreichen der Öffnungsstellung des Torblattes auf die Fangeinrichtung übertragenen Kräfte nicht in die Führungsschiene, sondern in die Konsole eingeleitet werden, die an der Mauerung des Gebäudes befestigt ist und an der gleichfalls die Halterung für die Wickelwelle oder eine sonstige Einrichtung für die Anordnung des Torblattes in einer anderen Position als die Schließstellung angeordnet ist, von wo aus ebenfalls Kräfte des in der Öffnungsstellung abgebremsten Torblattes übertragen und in das Mauerwerk abgeleitet werden, ohne daß auf die Führungsschiene Kräfte einwirken. Es hat sich gezeigt, daß durch diese Anordnung der Fangeinrichtung an der Konsole zusammen mit der Halterung, insbesondere der Wickelwelle, eine positive Beeinflussung der bei der Bewegung des Torblattes, insbesondere beim Erreichen der Endstellung mit dem damit verbundenen Abfangen des Torblattes auftretenden Kräfte erzielt wird, nämlich dahingehend, daß sich die Kräfte im Moment des Erreichens der Endstellung des Torblattes, nämlich in der Öffnungsstellung im wesentlichen so weit kompensieren, daß nur noch geringe Kräfte in das Mauerwerk eingeleitet werden müssen. Hierdurch ergeben sich insbesondere Vorteile bei der Dimensionierung der Befestigungselemente dieses Rolltores.The advantage of the roller door designed according to the invention is that the forces transmitted when the door leaf reaches the open position are not introduced into the guide rail, but into the console, which is attached to the wall of the building and on which the holder for the winding shaft or another device for the arrangement of the door leaf is arranged in a position other than the closed position, from which forces of the door leaf braked in the open position are also transmitted and derived into the masonry without any forces acting on the guide rail. It has been shown that this arrangement of the catching device on the console together with the holder, in particular the winding shaft, has a positive influence on the forces occurring when the door leaf moves, in particular when the end position is reached, with the associated interception of the door leaf. namely to the extent that the forces at the moment of reaching the end position of the door leaf, namely in the open position, essentially compensate so far that only small forces have to be introduced into the masonry. This results in particular advantages in the dimensioning of the fasteners of this roller shutter.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Konsole und die Halterung einstückig ausgebildet sind. Insbesondere besteht die Konsole aus einem im Querschnitt rechtwinklig, vorzugsweise quadratisch ausgebildetem Rohrstück, an welchem plattenförmige Befestigungselemente angeordnet, vorzugsweise angeschweißt sind. Mittels der plattenförmigen Befestigungselemente wird die Konsole am Mauerwerk verschraubt.According to a further feature of the invention it is provided that the console and the holder are formed in one piece. In particular, the bracket consists of a tube section of rectangular cross section, preferably square, on which plate-shaped fastening elements are arranged, preferably welded on. The bracket is screwed to the masonry using the plate-shaped fastening elements.

Die Halterung für die Wickelwelle besteht vorzugsweise aus zwei Traversen, die im Abstand zueinander angeordnet sind, parallel verlaufen und an ihrem freien Ende miteinander verbunden sind. Zwischen diesen Traversen ist die Wickelwelle verschiebbar geführt, so daß sich die Wickelwelle entsprechend dem bereits aufgewickelten Torblatt derart verschieben kann, daß das Torblatt immer in vertikaler Richtung in die Führungsschienen einläuft und in diesem Bereich nicht abgeknickt werden muß. Hierdurch wird ein leichtgängiges Öffnen und Schließen des Torblattes erzielt, was insbesondere bei handbetätigten Torblättern von besonderem Vorteil ist. Durch die verschiebbare Lagerung der Wickelwelle in der Halterung treten unterschiedliche Kräfte und Momente im Bereich der Halterung auf, die, insbesondere durch den bereits ab- bzw. aufgewickelten Abschnitt des Torblattes und die damit verbundene Stellung der Wickelwelle bestimmt sind. Bei vollständig aufgewickeltem Torblatt lastet das gesamte Gewicht des Torblattes auf der Wickelwelle, die durch den maximalen Durchmesser des aufgewickelten Torblattes in maximaler Entfernung von der Führungsschiene gelagert ist, so daß relativ zu der Führungsschiene ein großes Drehmoment auf die Halterung wirkt. Ist das Torblatt in seine Schließstellung überführt, so ist der wesentliche Teil des Torblattes von der Wickelwelle abgewickelt, wodurch der Durchmesser der Wickelwelle und des darauf aufgewickelten Torblattabschnittes minimal und dadurch auch das auf die Konsole wirkende Drehmoment bezüglich der Führungsschiene ebenfalls minimal ist.The holder for the winding shaft preferably consists of two crossbeams which are arranged at a distance from one another are parallel and are connected to each other at their free end. The winding shaft is slidably guided between these traverses, so that the winding shaft can move in accordance with the already wound door leaf in such a way that the door leaf always runs vertically into the guide rails and does not have to be bent in this area. This enables the door leaf to be opened and closed smoothly, which is particularly advantageous in the case of manually operated door leaves. Due to the displaceable mounting of the winding shaft in the holder, different forces and moments occur in the region of the holder, which are determined, in particular, by the section of the door leaf which has already been unwound or wound up and the position of the winding shaft associated therewith. When the door leaf is fully wound, the entire weight of the door leaf rests on the winding shaft, which is supported by the maximum diameter of the wound door leaf at the maximum distance from the guide rail, so that a large torque acts on the holder relative to the guide rail. If the door leaf is transferred to its closed position, the major part of the door leaf is unwound from the winding shaft, as a result of which the diameter of the winding shaft and the door leaf section wound thereon is minimal and the torque acting on the bracket with respect to the guide rail is also minimal.

Vorzugsweise verläuft die Halterung unter einem Winkel von insbesondere 45° zur Längsachse der Konsole, so daß eine Hangabtriebskraft erzeugt wird, die die Wickelwelle mit aufgewickeltem Torblatt in Richtung auf die Führungsschienen drückt, wodurch der Schließvorgang des Rolltores unterstützt wird.Preferably, the bracket extends at an angle of in particular 45 ° to the longitudinal axis of the console, so that a downward force is generated which presses the winding shaft with the wound door leaf in the direction of the guide rails, thereby supporting the closing process of the roller shutter.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Feder als Schraubenfeder ausgebildet ist und sich mit einem Ende an der Konsole abstützt und mit ihrem zweiten Ende in den Bewegungsraum des Torblattes ragt, wo sie bei in die Öffnungsstellung verfahrenem Torblatt mit einem Anschlag zusammenwirkt, der im Abschlußkantenbereich des Torblattes angeordnet ist. Die Schraubenfeder weist hierbei an ihrem, der Konsole zugewandten Ende einen abgewinkelten Arm auf, der in eine korrespondierende Bohrung in der Konsole eingreift, so daß die über die Schraubenfeder durch das sich in die Öffnungsstellung bewegende Torblatt eingeleiteten Kräfte direkt in die Konsole eingeleitet werden.According to a further feature of the invention it is provided that the spring is designed as a helical spring and is supported at one end on the console and protrudes with its second end into the movement area of the door leaf, where it also moves with the door leaf moved into the open position a stop cooperates, which is arranged in the end edge region of the door leaf. The coil spring has an angled arm at its end facing the console, which engages in a corresponding bore in the console, so that the forces introduced via the coil spring by the door leaf moving into the open position are introduced directly into the console.

Schließlich ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß der Anschlag als Rolle und das freie Ende der Feder entsprechend dem Umfang der Rolle gebogen ausgebildet ist. Hierdurch wird insbesondere der Vorteil erzielt, daß der Anschlag beim Erreichen seiner Endstellung in der Öffnungsstellung des Torblattes sicher von dem Fangelement aufgenommen und abgebremst wird.Finally, according to a further feature of the invention it is provided that the stop is designed as a roller and the free end of the spring is curved in accordance with the circumference of the roller. This has the particular advantage that the stop is reliably picked up and braked by the catch element when it reaches its end position in the open position of the door leaf.

Das Torblatt 2 ist entlang der Führungsschienen 1 zwischen einer Öffnungsstellung und einer Schließstellung hin- und hergehend bewegbar, wobei die Bewegung handbetätigt ausgeführt wird.The door leaf 2 can be moved back and forth along the guide rails 1 between an open position and a closed position, the movement being carried out manually.

Wird das Torblatt 2 aus seiner Schließstellung in die Öffnungsstellung überführt, so wird das Torblatt 2 auf einer Wickelwelle 3 aufgewickelt, wobei diese Wickelwelle 3 über Torsionsfedern gegenüber dem Mauerwerk abgestützt ist, so daß die Torsionsfedern, welche in der Figur 1 nicht dargestellt sind, die Aufwärtsbewegung des Torblattes 2 unterstützen, d. h. während der Aufwärtsbewegung des Torblattes 2 entspannt und während der Abwärtsbewegung des Torblattes 2 gespannt werden.If the door leaf 2 is transferred from its closed position into the open position, the door leaf 2 is wound on a winding shaft 3, this winding shaft 3 being supported against the masonry by torsion springs, so that the torsion springs, which are not shown in FIG Support upward movement of the door leaf 2, d. H. relaxed during the upward movement of the door leaf 2 and tensioned during the downward movement of the door leaf 2.

Die Wickelwelle 3 ist in einer Halterung 4 gelagert. Wie aus den Figuren 2 bis 4 zu erkennen ist, besteht die Halterung 4 aus zwei parallel verlaufenden Traversen 5, die als im Querschnitt rechtwinklig ausgebildete Rohrabschnitte ausgebildet sind. Die Traversen 5 sind unter einem Winkel von 45° zur Längsachse der im Querschnitt U-förmig ausgebildeten Führungsschiene 1 an einer Konsole 6 angeschweißt. Darüber hinaus tragen die Traversen 5 ein an ihren freien Enden angeordnetes Begrenzungselement 7, das an den Traversen 5 angeschweißt ist.The winding shaft 3 is mounted in a holder 4. As can be seen from FIGS. 2 to 4, the holder 4 consists of two parallel traverses 5, which are designed as tubular sections of rectangular cross section. The cross members 5 are welded to a bracket 6 at an angle of 45 ° to the longitudinal axis of the guide rail 1 which is U-shaped in cross section. In addition, the trusses 5 enter at its free ends arranged limiting element 7 which is welded to the cross members 5.

Die Wickelwelle 3 ist gemäß Figur 2 über einen U-förmigen Bügel 8 und zwei an dessen Enden aufgeschraubten U-förmig ausgebildeten Führungselementen 9 an den Traversen 5 derart befestigt, daß die Wickelwelle 3 entsprechend des Durchmessers des aufgewickelten Torblattes 2 entlang der Traversen 5 in der Art bewegbar geführt ist, daß das Torblatt 2 unabhängig vom Umfang des aufgewickelten Torblattes 2 senkrecht in die Führungsschiene 1 einläuft, so daß ein Abknicken des Torblattes 2 im Bereich des oberen, der Wickelwelle 3 zugewandten Endes der Führungsschiene 1, vermieden wird.The winding shaft 3 is fixed according to Figure 2 via a U-shaped bracket 8 and two screwed on its ends U-shaped guide elements 9 to the cross members 5 such that the winding shaft 3 according to the diameter of the wound door leaf 2 along the cross members 5 in the Type is guided movably that the door leaf 2 runs vertically into the guide rail 1 regardless of the extent of the wound door leaf 2, so that kinking of the door leaf 2 in the region of the upper end of the guide rail 1 facing the winding shaft 3 is avoided.

Der U-förmige Bügel 8 umgreift die Wickelwelle 3 und ist zwischen den beiden parallelen Traversen 5 der Halterung 4 durchgesteckt. An seinen zwischen den beiden Traversen 5 durchgreifenden Enden weist der U-förmige Bügel 8 ein Gewinde auf. Über diese Enden des U-förmigen Bügels 8 sind die Führungselemente 9 derart aufgesteckt und mit Muttern 10 an dem U-förmigen Bügel 8 gesichert, daß die U-förmigen Führungselemente 9 beide parallel verlaufenden Traversen 5 übergreifen und mit den Innenflächen ihrer freien Schenkel an den Außenflächen der Traversen 5 anliegen. Die Wickelwelle 3 ist somit entlang der Traversen 5 verschiebbar.The U-shaped bracket 8 engages around the winding shaft 3 and is inserted between the two parallel cross members 5 of the holder 4. At its ends reaching through between the two cross members 5, the U-shaped bracket 8 has a thread. About these ends of the U-shaped bracket 8, the guide elements 9 are attached and secured with nuts 10 on the U-shaped bracket 8 that the U-shaped guide elements 9 overlap both parallel cross members 5 and with the inner surfaces of their free legs to the Fit the outer surfaces of the crossbeams 5. The winding shaft 3 is thus displaceable along the crossbeams 5.

Die Konsole 6 besteht aus einem im Querschnitt rechtwinklig ausgebildeten Rohabschnitt, an dessen einer Außenfläche eine L-förmiger Winkel 11 angeschweißt ist. Ferner sind an der Konsole 6 zwei plattenförmige Befestigungselemente 12 und 13 angeschweißt, mit denen die Konsole 6 an dem in der Figur 2 dargestellten Mauerwerk 14 über entsprechende Bolzen 15 befestigbar ist. Die Befestigungsplatten 12 und 13 weisen hierzu jeweils eine Bohrung 16 bzw. 17 auf, durch welche die Bolzen 15 steckbar sind.The console 6 consists of a raw section of rectangular cross section, on the outer surface of which an L-shaped bracket 11 is welded. Furthermore, two plate-shaped fastening elements 12 and 13 are welded to the bracket 6, with which the bracket 6 can be fastened to the masonry 14 shown in FIG. 2 via corresponding bolts 15. For this purpose, the fastening plates 12 and 13 each have a bore 16 or 17, through which the bolts 15 can be inserted.

In der Konsole 6 ist ferner im Bereich des im Querschnitt rechtwinklig ausgebildeten Rohrabschnitts eine weitere Bohrung 18 angeordnet, deren Funktion nachfolgend noch erläutert wird.In the console 6 there is also another in the region of the tube section which is rectangular in cross section Bore 18 arranged, the function of which will be explained below.

Zwischen dem Abschlußbereich des Torblattes 2 und dem von der Abschlußkante des Torblattes 2 abgewandten Endrandbereich der mit dem Torblatt abzuschließenden Toröffnung oder dergleichen ist eine sich über einen Restweg des Torblattes 2 bei dessen Übergang in die Öffnungslage spannende Fangeinrichtung angeordnet, die aus einer Feder 19 und einer am Torblatt 2 befestigten Rolle 20 besteht. Die Feder 19 ist in den Figuren 5 und 6 detailliert dargestellt und besteht aus einem im Querschnitt kreisförmig ausgebildeten Federstahl, der in seinem Mittelbereich in Form einer Wendel 21 aufgewickelt ist. Das eine Ende 22 der Feder 19 ist kreisbogenabschnittförmig derart ausgebildet, daß der Innenradius des kreisbogenabschnittförmigen Endes 22 der Feder 19 mit dem Außendurchmesser einer umlaufenden Ringnut in der Rolle 20 übereinstimmt. Das gegenüberliegende zweite Ende 23 der Feder 19 ist demgegenüber derart rechtwinklig abgewinkelt, daß es parallel zur Längsachse der Wendel 21 verläuft.Between the end area of the door leaf 2 and the end edge area facing away from the end edge of the door leaf 2 of the door opening to be closed with the door leaf or the like, a catching device is arranged over a remaining path of the door leaf 2 during its transition into the open position, which consists of a spring 19 and a spring roller 20 attached to the door leaf 2. The spring 19 is shown in detail in FIGS. 5 and 6 and consists of a spring steel which is circular in cross section and which is wound in the form of a coil 21 in its central region. One end 22 of the spring 19 is formed in the shape of a circular arc in such a way that the inner radius of the end 22 of the spring 19 in the shape of a circular arc corresponds to the outer diameter of a circumferential annular groove in the roller 20. The opposite second end 23 of the spring 19 is angled at such a right angle that it runs parallel to the longitudinal axis of the coil 21.

Die Feder 19 ist mittels eines in den Figuren 7 und 8 dargestellten Befestigungselementes 24 an dem Winkel 11 befestigt. Hierzu ist das Befestigungselement 24 im Querschnitt U-förmig ausgebildet, wobei die beiden Schenkel 25 an ihren freien Enden nach außen abgebogen sind. Das Befestigungselement 24 ist somit im wesentlichen topfförmig ausgebildet und weist in seinem Boden 26 eine Bohrung 27 auf, durch welche ein Bolzen steckbar ist, der eine Bohrung 28 im freien Schenkel des Winkels 11 durchgreift, so daß das Befestigungselement 24 mit dem Winkel 11 verschraubt ist.The spring 19 is fastened to the angle 11 by means of a fastening element 24 shown in FIGS. 7 and 8. For this purpose, the fastening element 24 is U-shaped in cross section, the two legs 25 being bent outwards at their free ends. The fastening element 24 is thus essentially pot-shaped and has in its base 26 a bore 27 through which a bolt can be inserted, which extends through a bore 28 in the free leg of the angle 11, so that the fastening element 24 is screwed to the angle 11 .

Wie insbesondere aus der Figur 1 zu erkennen ist, durchgreift das Befestigungselement 24 die Wendel 21 der Feder 19 in der Art, daß die Feder 19 zwischen den abgebogenen Enden der Schenkel 25 des Befestigungselementes 24 und dem Winkel 11 gehalten ist. Das Ende 22 der Feder 19 ragt in den Bewegungsraum des Torblattes 2 derart ein, daß die an dem Torblatt 2 angeordnete Rolle 20 bei Erreichen der Öffnungsstellen in den kreisbogenabschnittförmig ausgebildeten Bereich der Feder 19 einläuft und über die Wendel 21 federnd abgefangen wird. Das zweite Ende 23 der Feder 19 ist in die Bohrung 18 der Konsole 6 eingesteckt, so daß die von dem sich aufwärtsbewegenden Torblatt 2 auf die Feder 19 übertragenen Kräfte über das zweite Ende 23 der Feder 19 auf die Konsole 6 weitergeleitet werden. Diese Kräfte werden dann von der Konsole 6 in das Mauerwerk 14 über die Bolzen 15 eingeleitet.As can be seen in particular from FIG. 1, the fastening element 24 extends through the helix 21 of the spring 19 in such a way that the spring 19 is held between the bent ends of the legs 25 of the fastening element 24 and the angle 11. The end 22 of the spring 19 protrudes into the movement space of the door leaf 2 such that the roller 20 arranged on the door leaf 2 runs into the region of the spring 19 in the form of an arcuate section when the opening points are reached and is resiliently intercepted via the helix 21. The second end 23 of the spring 19 is inserted into the bore 18 of the bracket 6, so that the forces transmitted from the upward moving door leaf 2 to the spring 19 are transmitted to the bracket 6 via the second end 23 of the spring 19. These forces are then introduced from the console 6 into the masonry 14 via the bolts 15.

Das voranstehend beschriebene Rolltor hat insbesondere den Vorteil, daß die beim Abbremsen der Aufwärtsbewegung des Torblattes 2 auftretenden Kräfte über die Fangeinrichtung, bestehend aus der Feder 19 und der Rolle 20, unmittelbar in die Konsole 6 und damit in das Mauerwerk 14 eingeleitet werden, wobei die Konsole 6 in vorteilhafter Weise unmittelbar mit der Halterung 4 verbunden ist, über welche die Reaktionskräfte des sich auf der Wickelwelle 3 aufwickelnden Torblattes ebenfalls in das Mauerwerk 14 eingeleitet werden, wobei die Einleitung dieser unterschiedlichen Kräfte insbesondere nicht in die Führungsschienen 1 erfolgt.The roller door described above has the particular advantage that the forces occurring when braking the upward movement of the door leaf 2 via the catching device, consisting of the spring 19 and the roller 20, are introduced directly into the console 6 and thus into the masonry 14, the Console 6 is advantageously connected directly to the holder 4, via which the reaction forces of the door leaf which is wound on the winding shaft 3 are likewise introduced into the masonry 14, the different forces not being introduced into the guide rails 1 in particular.
