Description

Die Erfindung betrifft ein Sektionaltor mit

  • Torzarge,
  • einem Torblatt aus gelenkig verbundenen Sektionen,
  • einer an das Torblatt angeschlossenen Gewichtsausgleichseinrichtung und
  • einem elektrischen Torantrieb für Öffnungs- und Schließbewegungen des Torblattes,
wobei die in Torblattschließstellung oberste Sektion als Kopfsektion an Laufschienen geführt ist, die sich im Wesentlichen horizontal bis zur Torzarge erstrecken und zargenseitig einen vertikalen Endabschnitt aufweisen, und wobei die unterhalb der Kopfsektion anschließenden weiteren Sektionen in Führungsschienen geführt sind, die einen vertikalen Abschnitt entlang der Torzarge, einen horizontalen Abschnitt parallel zu der die Kopfsektion führenden Laufschiene sowie einen die beiden Abschnitte verbindenden Bogen aufweisen.The invention relates to a sectional door with
  • door frame,
  • a door leaf of articulated sections,
  • a weight balancing device connected to the door leaf and
  • an electric door drive for opening and closing movements of the door leaf,
wherein the uppermost in Torblattschließstellung section is guided as a head section of rails that extend substantially horizontally to the door frame and the frame side have a vertical end portion, and wherein the subsequent below the head section further sections are guided in guide rails, a vertical portion along the door frame , Have a horizontal portion parallel to the head section leading rail and an arc connecting the two sections.

Sektionaltore der eingangs beschriebenen Art müssen den in der europäischen Norm EN 12453:2000 beschriebenen Sicherheitsanforderungen genügen. Darin ist festgelegt, dass während eines Öffnungs- bzw. Schließvorganges des Torblattes eine dynamische Kraft zwischen Schließkanten und Gegenschließkanten von maximal 400 N auftreten darf. Derart hohe Kräfte sind jedoch nur für einen Zeitraum von maximal 0,75 Sekunden zugelassen. Nach Ablauf dieser Zeitspanne ist keine statische Kraft erlaubt, die mehr als 150 N beträgt. Bei den in der Praxis bekannten Sektionaltoren mit den eingangs beschriebenen Merkmalen wird während einer regulären Öffnungs- bzw. Schließbewegung des Torblattes eine tolerierte statische Kraft von 150 N innerhalb des zulässigen Rahmens kurzzeitig häufig überschritten, so dass leistungsstarke Torantriebe eingesetzt werden müssen. Sofern die erforderliche Kraft zur Bewegung des Torblattes über eine Zeitdauer von mehr als 0,75 s hinweg mehr als 150 N beträgt, muss der Torantrieb durch eine Notabschaltung abgeschaltet werden. Bei einer Fehlfunktion der Notabschaltung besteht eine erhebliche Verletzungsgefahr. Problematisch ist auch, dass der im Rahmen der bekannten Maßnahmen an der obersten Torblattsektion befestigte Antrieb weit von der Gefahrenstelle, nämlich der unteren Schließkante entfernt ist, so dass ein langer Kraftfluss vom Motor über die gelenkig miteinander verbundenen Paneele bis zur Gefahrenstelle vorliegt. Eine Reduzierung der Antriebskraft des Motors schafft daher erst nach einer gewissen Verzögerungszeit eine entsprechende Entlastung an der Gefahrenstelle.Sectional doors of the type described above must meet the safety requirements described in the European standard EN 12453: 2000. It stipulates that during an opening or closing operation of the door leaf a dynamic force between closing edges and Gegenschließkanten of a maximum of 400 N may occur. However, such high forces are only permitted for a maximum period of 0.75 seconds. To During this period, no static force exceeding 150 N is allowed. In the known in practice sectional doors with the features described above, during a regular opening or closing movement of the door leaf, a tolerated static force of 150 N within the allowable frame often exceeded for a short time, so that powerful door drives must be used. If the force required to move the door leaf exceeds 150 N over a period of more than 0.75 s, the door drive must be switched off by emergency shutdown. In the event of a malfunction of the emergency shutdown, there is a considerable risk of injury. Another problem is that the drive mounted in the known measures on the top door panel section is far away from the danger point, namely the lower closing edge, so that there is a long power flow from the engine through the hinged panels to the danger point. A reduction in the driving force of the engine therefore only after a certain delay time creates a corresponding discharge at the danger point.

Der vergleichsweise hohe Kraftbedarf während der Öffnungs- und Schließbewegungen bei bekannten Sektionaltoren beruht u.a. auf dem folgenden Sachverhalt. Die Kopfsektion des Torblattes weist an beiden Seiten jeweils eine Laufrolle auf, die in einer zugeordneten horizontalen Laufschiene geführt ist. Die horizontalen Laufschienen sind zargenseitig mit einem vertikalen Endabschnitt versehen, in den die Laufrollen der obersten Sektion bei einer Schließbewegung des Torblattes hineingezogen werden. Die in die vertikalen Endstücke eingeführten Laufrollen sichern die Kopfsektion in der Torblattschließstellung gegen ein unbefugtes Aufdrücken von außen. Bei einer Öffnungsbewegung des Torblattes müssen die Laufräder der Kopfsektion zunächst eine vertikale Strecke überwinden, bevor sie dann in den horizontalen Bereich der Laufschiene gelangen. Diese Hubbewegung zu Beginn der Öffnungsbewegung des Torblattes bildet ein technisches Problem für den elektrischen Torantrieb.The comparatively high power requirement during the opening and closing movements in known sectional doors is based inter alia on the following facts. The head section of the door leaf has on both sides in each case a roller, which is guided in an associated horizontal track rail. The horizontal rails are provided on the frame side with a vertical end portion, in which the rollers of the top section are pulled in at a closing movement of the door leaf. The rollers inserted in the vertical end pieces secure the head section in the door leaf closing position against unauthorized pressing from the outside. During an opening movement of the door leaf, the wheels of the head section must first overcome a vertical distance before they then enter the horizontal region of the running rail. This lifting movement at the beginning of Opening movement of the door leaf forms a technical problem for the electric door drive.

Ein Sektionaltor mit den eingangs beschriebenen Merkmalen ist aus EP-A 1 176 280 bekannt. Der elektrische Torantrieb ist entlang einer horizontalen Laufschiene verfahrbar und durch eine Kupplungsstange an die Kopfsektion angeschlossen. In der Torblattschließstellung ist die Kupplungsstange schräg zur Torblattebene ausgerichtet. Die bei einer Öffnungsbewegung des Torblattes mit der Kupplungsstange übertragene Zugkraft besitzt eine horizontale sowie eine vertikale Komponente. Infolge der vertikalen Komponente kann die Laufrolle der Kopfsektion mit einer Fahrbewegung des Torantriebes aus dem vertikalen Endabschnitt der vertikalen Laufschiene herausgezogen werden. Jedoch sind leistungsstarke Torantriebe erforderlich, die das bereits beschriebene Gefahrenpotential aufweisen. Nachteilig ist bei der bekannten Anordnung auch, dass die Kopfsektion in Torblattschließstellung und der vertikale Endabschnitt der Laufschiene zu Beginn einer Öffnungsbewegung großen Querkräften ausgesetzt sind.A sectional door with the features described above is made EP-A 1 176 280 known. The electric door drive is moved along a horizontal track and connected by a coupling rod to the head section. In the Torblattschließstellung the coupling rod is aligned obliquely to the door leaf level. The transmitted during an opening movement of the door leaf with the coupling rod tensile force has a horizontal and a vertical component. Due to the vertical component, the roller of the head section can be pulled out with a driving movement of the door drive from the vertical end portion of the vertical track rail. However, powerful door drives are required, which have the risk described above. A disadvantage of the known arrangement also that the head section in Torblattschließstellung and the vertical end portion of the running rail at the beginning of an opening movement are exposed to large transverse forces.

Bei einem aus US 2 015 402 bekannten Sektionaltor ist die Kopfsektion des Torblatts an Laufschienen geführt, die sich im Wesentlichen horizontal bis zur Torzarge erstrecken. An den horizontalen Laufschienen sind keine vertikalen Endabschnitte vorgesehen. Für Öffnungs- und Schließbewegungen des Torblatts ist ein Torantrieb vorgesehen, der entweder an der Kopfsektion oder einer Sektion unterhalb der Kopfsektion angeschlossen ist und ein als Ritzel ausgebildetes angetriebenes Laufrad aufweist. Das angetriebene Laufrad kämmt mit einer profilierten Fläche, die entlang einer Laufschiene oder Führungsschiene angeordnet ist.At one off US 2 015 402 known sectional door the head section of the door leaf is guided on rails, which extend substantially horizontally to the door frame. On the horizontal rails no vertical end sections are provided. For opening and closing movements of the door leaf, a door drive is provided, which is connected to either the head section or a section below the head section and has a trained as a pinion driven impeller. The driven impeller meshes with a profiled surface, which is arranged along a running rail or guide rail.

Der Erfindung liegt die Aufgabe zugrunde, ein Sektionaltor mit den eingangs beschriebenen Merkmalen anzugeben, von dem eine reduzierte Verletzungsgefahr ausgeht. Dabei soll in jeder Stellung des Torblattes während einer Öffnungs- und Schließbewegung eine günstige Krafteinleitung von dem Torantrieb auf das Torblatt gewährleistet sein.The invention has for its object to provide a sectional door with the features described above, from which a reduced risk of injury emanates. It should be guaranteed in each position of the door leaf during an opening and closing movement a favorable force from the door drive on the door leaf.

Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein Sektionaltor nach Anspruch 1.The object of the invention and solution of this problem is a sectional door according to claim 1.

Erfindungsgemäß ist der Torantrieb an einer der unterhalb der Kopfsektion angeschlossenen Sektionen befestigt und weist mindestens eine an der Sektion gelagerte Abtriebswelle mit einem endseitigen Laufrad auf, welches in die Führungsschiene der Sektion eingreift und das Torblatt bewegt.According to the door drive is attached to one of the sections connected below the head section and has at least one output shaft mounted on the output shaft with an end-side impeller, which engages in the guide rail of the section and moves the door leaf.

Erfindungsgemäß ist der Torantrieb an der Torblattinnenfläche einer Sektion fest montiert und treibt ein Laufrad an, das in eine der Führung der Sektionen dienende Führungsschiene eingreift. Die Führungsschiene besitzt einen vertikalen Abschnitt entlang der Torzarge, einen horizontalen Abschnitt parallel zu der die Kopfsektion führenden Laufschiene sowie einen die beiden Abschnitte verbindenden Bogen. Bei einer Schließbewegung des Torblattes läuft das angetriebene Laufrad in den vertikalen Abschnitt der Führungsschiene ein. Bei einer nachfolgenden Öffnungsbewegung werden die Laufrollen der Kopfsektion durch die zunächst vertikale Verfahrbewegung der angetriebenen Laufräder aus den gekröpften Endbereichen der horizontalen Laufschiene herausgehoben. Unter anderem können aufgrund der günstigen Krafteinleitung verhältnismäßig schwache Torantriebe eingesetzt werden, so dass die Gefahr einer Verletzung während einer Öffnungs- und Schließbewegung des Torblattes reduziert wird.According to the door drive is fixedly mounted on the door leaf inner surface of a section and drives an impeller which engages in a guide rail of the sections serving guide rail. The guide rail has a vertical portion along the door frame, a horizontal portion parallel to the leading edge of the head rail and an arc connecting the two sections. During a closing movement of the door leaf, the driven impeller enters the vertical section of the guide rail. In a subsequent opening movement, the rollers of the head section are lifted out of the cranked end portions of the horizontal track by the initially vertical movement of the driven wheels. Among other things, due to the favorable introduction of force relatively weak door drives can be used, so that the risk of injury during an opening and closing movement of the door leaf is reduced.

Gemäß einer bevorzugten Ausführung der Erfindung ist der Torantrieb an der in Torblattschließstellung untersten Sektion befestigt. Überraschenderweise wird hierdurch auch die nach dem Herausheben der Laufrollen der Kopfsektion aus den gekröpften Endbereichen der horizontalen Laufschiene erforderliche Kraft zum Bewegen des Torblattes im Vergleich zum Stand der Technik deutlich reduziert. Durch die Anordnung des Torantriebes an der in Torblattschließstellung untersten Sektion liegt ferner ein kurzer Kraftfluss zwischen dem Torantrieb und der potentiellen Gefahrenstelle an der bodenseitigen Schließkante des Torblattes vor, so dass eine Abschaltung des Torantriebes zu einer sehr schnellen Entlastung an der Gefahrenstelle führt.According to a preferred embodiment of the invention, the door drive is attached to the bottom in Torblattschließstellung section. Surprisingly, as a result, the force required to lift the door leaf out of the cranked end regions of the horizontal running rail after the rollers have been lifted out of the head section is also significantly reduced in comparison with the prior art. Due to the arrangement of the door drive at the lowest in Torblattschließstellung section is also a short power flow between the door drive and the potential danger spot on the bottom-side closing edge of the door leaf, so that a shutdown of the door drive leads to a very rapid relief at the danger point.

Erfindungsgenmäß ist der Torantrieb so dimensioniert, dass die maximale Antriebskraft zum Bewegen des Torblattes nicht mehr als 150 N beträgt. Bei der Anordnung von zwei oder mehr Motoren erfolgt die Dimensionierung entsprechend so, dass die gesamte maximale Antriebskraft unterhalb des genannten Grenzwertes liegt. Bei der erfindungsgemäßen Anordnung des Torblattantriebes werden die genannten kritischen Kraftwerte von mehr als 150 N während des regulären Öffnungs- bzw. Schließvorganges eines Torblattes, das Standardabmessungen für eine Garage mit einem oder zwei PKW-Einstellplätzen aufweist, nicht erreicht, so dass die Funktion des Torblattes auch bei der reduzierten Antriebsleistung des Torantriebes gewährleistet ist. Der eingangs erläuterte dynamische Bereich zwischen 150 N und 400 N, innerhalb dessen ein erhöhtes Verletzungsrisiko vorliegt, kann somit niemals erreicht werden. Eine Notabschaltung bei einem Überschreiten des kritischen Wertes von 150 N über einen Zeitraum von mehr als 0,75 s hinweg ist daher entbehrlich. Alternativ kann die Notabschaltung auf einen niedrigeren Kraftbegrenzungswert eingestellt werden. Neben dem Vorteil, dass ein inhärent verletzungssicheres System vorliegt, bestehen aufgrund der Verwendung eines kleineren Torantriebes auch Kostenvorteile.According to the invention, the door drive is dimensioned such that the maximum driving force for moving the door leaf is not more than 150 N. In the arrangement of two or more motors, the dimensioning is done so that the total maximum driving force is below the specified limit. In the inventive arrangement of the Torblattantriebes said critical force values of more than 150 N during the regular opening and closing operation of a door leaf, the standard dimensions for a garage with one or two car parking spaces not reached, so that the function of the door leaf is ensured even with the reduced drive power of the door drive. The above-explained dynamic range between 150 N and 400 N, within which there is an increased risk of injury, can thus never be achieved. An emergency shutdown when the critical value of 150 N is exceeded over a period of more than 0.75 s is therefore superfluous. Alternatively, the emergency shutdown can be set to a lower force limit value. In addition to the advantage that an inherently injury-resistant system is present, there are also cost advantages due to the use of a smaller door drive.

Der Torantrieb kann ein Verzweigungsgetriebe für zwei Abtriebswellen aufweisen, die sich bis zu den beiden Seiten der Sektionen erstrecken und endseitige, in die Führungsschienen eingreifenden Laufräder aufweisen.
