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 hand-operated door leaf, which is in the guide rails between one Open and a closed position is performed, wherein between the end area of the door leaf and that of the end edge of the end edge facing away from the end edge of the door leaf the door opening to be closed with the door leaf or the like at least one over a remaining distance the door leaf at its transition to the open position exciting safety gear or the like arranged is.

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 shutter is, for example, from EP 0 362 585 B1 previously known. This is a Rolling door in basically known design with Guide rails or guide profiles in which the Side edges of the door leaf between the closed position and the opening position are guided. Such door leaves are usually rolled up and down on rollers, but they can also be used in the transition to the open position be moved to another position. Especially if such roller shutters are confirmed by hand the goal is to make the door leaves lightweight To design for the movement process to keep the required force small. Here come door leaves from successive profiles in the direction of movement into consideration, for example made of aluminum or also so-called curtains from continuous, corresponding flexible Foils and the like. When transferring the Door leaf in the open state there is a risk that with a correspondingly high delay at the end of the door leaf movement its termination area, for example a End profile or a correspondingly small slatted area of a curtain due to the still existing in it Kinetic energy slips over the roll. At the Closing with appropriate acceleration at the beginning of the movement process can the inertia of the final area of the door leaf cause that the side facing away from the door opening to be closed Forms loop. A difficult training in the final area the door leaf, for example by inserting a Flat iron, can only influence this behavior to a limited extent and stands by the intended easy education of the door leaf as a whole. To at such a Door leaf high accelerations and decelerations too enable without the closing area of the door leaf irregular compared to the other door leaf area moves, sees the roller shutter according to EP 0 362 585 B1 a catching device that consists of at least one on one Guide rail attached spring and one at the end edge area of the door leaf arranged roller, when moving the door leaf into the open position runs onto the spring so that the door leaf of the Spring is springily intercepted in its open position. Here, those transferred from the door leaf to the spring Forces 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 moved into 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 Position is connected.

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 shutter designed according to the invention is that when the door leaf reaches the open position forces transmitted to the safety gear not in the guide rail, but introduced into the console be attached to the wall of the building and on the holder for the winding shaft or another device for the arrangement of the door leaf in a different position than the closed position is arranged, from where also forces in the Transfer the opening position of the braked door leaf and can be derived into the masonry without the Actuate guide rail forces. It has shown, that by this arrangement of the safety gear on the console together with the holder, especially the winding shaft, a positive influence on the movement the door leaf, especially when it reaches the end position with the associated interception of the door leaf occurring forces is achieved, namely in that that the forces at the moment of reaching the end position of the door leaf, namely in the open position in compensate so much that only a small amount Forces must be introduced into the masonry. Hereby there are particular advantages in dimensioning 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, that the console and the bracket are integrally formed are. In particular, the console consists of a cross section rectangular, preferably square Pipe piece on which plate-shaped fasteners arranged, preferably welded. Means the plate-shaped fasteners Bracket screwed to the masonry.

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.The holder for the winding shaft is preferably from two crossbeams, spaced apart are parallel and at their free end with each other are connected.

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.The bracket preferably extends at an angle of in particular 45 ° to the longitudinal axis of the console, so that a downward slope is generated which is the winding shaft with the door leaf rolled up in the direction of the guide rails presses, causing the roller shutter to close is supported.

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, that the spring is designed as a coil spring and itself with one end supported on the console and with her second end protrudes into the movement area of the door leaf where with the door leaf moved to the open position a stop that interacts in the end edge area of the door leaf is arranged. The coil spring has one at its end facing the console angled arm on which corresponds to a Hole engages in the console so that the over Coil spring by moving into the open position Forces imposed directly into the console be initiated.

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, another feature of the invention provided that the stop as a roller and the free end the spring is curved according to the circumference of the roller is. This has the particular advantage of that the stop when it reaches its end position in the open position of the door leaf Catch element is picked up and braked.

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 between the two parallel cross members 5 of the bracket 4 inserted. On his between the two trusses The U-shaped bracket 8 has 5 reaching ends Thread on. About these ends of the U-shaped bracket 8 are the guide elements 9 plugged in and with Nuts 10 secured to the U-shaped bracket 8 that the U-shaped guide elements 9 both parallel Cross bars 5 and overlap with the inner surfaces of their rest the free leg on the outer surfaces of the trusses 5. The winding shaft 3 is thus along the crossbars 5 slidable.

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 rectangular cross section trained raw section, on one outer surface an L-shaped bracket 11 is welded. Further are on the console 6 two plate-shaped fasteners 12 and 13 welded with which the console 6 on the masonry 14 shown in FIG corresponding bolt 15 can be fastened. The mounting plates For this purpose, 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 is also in the area of the cross section right-angled pipe section another Bore 18 arranged, their function below is explained.

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 that of the end edge of the door leaf 2 facing away from the end edge area the door opening to be closed with the door leaf or the like is one over a remaining distance of Door leaf 2 at its transition to the open position exciting safety gear arranged from a spring 19 and a roller 20 attached to the door leaf 2. The spring 19 is shown in detail in FIGS. 5 and 6 and consists of a circular cross section trained spring steel, which in its central area in Form of a coil 21 is wound. One end 22 the spring 19 is designed in the form of an arc of a circle, that the inner radius of the arcuate section End 22 of the spring 19 with the outer diameter of one circumferential annular groove in the roller 20 matches. The opposite second end 23 of the spring 19 is in contrast so angled at right angles that it is parallel runs to the longitudinal axis of the helix 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 by means of one in FIGS. 7 and 8 Fastening element 24 shown at the angle 11 attached. For this purpose, the fastening element 24 is in cross section U-shaped, the two legs 25 are bent outwards at their free ends. The Fastening element 24 is thus essentially pot-shaped formed and has a bore in its bottom 26 27, through which a bolt can be inserted, one Bore 28 penetrates in the free leg of the angle 11, so that the fastener 24 is screwed to the bracket 11 is.

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 the fastener 24 the coil 21 of the spring 19 in such a way that the spring 19 is bent between the Ends of the legs 25 of the fastener 24 and the angle 11 is held. The end 22 of the spring 19 protrudes in the movement space of the door leaf 2 such that the roller 20 arranged on the door leaf 2 upon reaching the Opening points in the arcuate section Area of the spring 19 runs in and over the coil 21 is resiliently intercepted. The second end 23 of the Spring 19 is inserted into the bore 18 of the bracket 6, so that from the upward moving door leaf 2 the spring 19 transmitted forces via the second end 23 the spring 19 can be forwarded to the console 6. These forces are then from the console 6 into the masonry 14 initiated via the bolt 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 in particular the advantage that when braking the upward movement the door leaf 2 forces occurring via the safety gear, consisting of the spring 19 and the roller 20, directly into the console 6 and thus into the masonry 14 are initiated, the console 6 being advantageous Is directly connected to the holder 4, through which the reaction forces of the itself on the winding shaft 3 winding door leaf also in the masonry 14 are initiated, the initiation of this different forces in particular not in the guide rails 1 is done.
