Description

Die Erfindung betrifft ein Dichtungselement für ein Torblatt eines Tores, insbesondere Sektionaltores mit mindestens einer von mindestens einer verformbaren Wand begrenzten und an ihren axialen Enden verschlossenen Kammer, ein Torblatt mit einem derartigen Dichtungselement und ein ein solches Torblatt aufweisendes Tor.The invention relates to a sealing element for a door leaf of a door, in particular Sectional doors with at least one bounded by at least one deformable wall and chamber closed at its axial ends, a door leaf with such a sealing element and a such a door leaf having gate.

Dichtungselemente der vorstehend beschriebenen Art werden beispielsweise zum dichten Verschließen einer Wandöffnung mit demTorblatt eines sog. Sektionaltores eingesetzt. Bei einem derartigen Sektionaltor ist das Torblatt zwischen einer Öffnungsstellung, in der es etwa in einer Horizontalebene über Kopf angeordnet ist, und einer Schließstellung, in der es in einer Vertikalebene ausgerichtet mit einer im allgemeinen geradlinig verlaufenden Kante am Boden des damit zu verschließenden Raumes anliegt, bewegbar. Ein Torblatt für ein derartiges Sektionaltor ist beispielsweise in der EP 0 370 376 B1 beschrieben. Der Offenbarungsgehalt dieser Schrift hinsichtlich der Ausführung eines Sektionaltorblattes wird hiermit durch ausdrückliche Inbezugnahme in diese Beschreibung aufgenommen.Sealing elements of the type described above are used for sealing a wall opening with the door leaf of a so-called sectional door. In such a sectional door, the door leaf is between an open position in which it is arranged approximately in a horizontal plane overhead, and a closed position, in which is aligned in a vertical plane with a generally straight line Edge on the floor of the room to be closed, movable. A door leaf for such a sectional door is described for example in EP 0 370 376 B1. The Disclosure content of this document with regard to the execution of a sectional door leaf hereby incorporated into this description by express reference.

Zum dichten Verschließen eines Raumes weisen derartige Torblätter im Bereich der in der Schließstellung unteren Kante, die auch als Hauptschließkante bezeichnet wird, ein Dichtungselement auf, das einerseits einen dichten Anschluß des Torblattes an den Boden sicherstellt und andererseits zum Ausgleichen kleinerer Bodenunebenheiten geeignet ist. Derartige Bodendichtungen sind üblicherweise aus einem Elastomermaterial gebildet und weisen mindestens eine von dem Elastomermaterial begrenzte und sich längs der Hauptschließkante erstreckende Hohlkammer auf.To close a room tightly, such door leaves have in the area of in the closed position lower edge, which is also referred to as the main closing edge Sealing element on the one hand, a tight connection of the door leaf to the floor ensures and on the other hand is suitable for compensating for smaller uneven floors. Such floor seals are usually made of an elastomeric material have at least one limited by the elastomer material and along the Main closing edge extending hollow chamber.

Beim Einsatz derartiger Dichtungselemente können Verschmutzungen und Feuchtigkeit in diese Hohlkammer eindringen. Angesichts dieses Mangels ist man dazu übergegangen, die Hohlkammern des sich längs der Hauptschließkante erstreckenden Dichtungselementes zu verschließen, um so das Eindringen von Schmutz und Feuchtigkeit in diese Hohlkammer zu verhindern. Derartige Anordnungen sind in der DE 298 09 129 U1 angegeben.When using such sealing elements, dirt and moisture can penetrate into this hollow chamber. In view of this lack, one is in favor passed, the hollow chambers extending along the main closing edge Seal the sealing element to prevent the ingress of dirt and moisture to prevent in this hollow chamber. Such arrangements are in DE 298 09 129 U1 specified.

Bei Einsatz von mit einem derartigen Dichtungselement ausgestatteten Torblättern wird jedoch häufig eine Beschädigung oder gar Zerstörung des Dichtungselementes beobachtet.When using door leaves equipped with such a sealing element will often damage or even destroy the sealing element observed.

Angesichts der vorstehend beschriebenen Probleme im Stand der Technik liegt der Erfindung die Aufgabe zugrunde ein Dichtungselement für ein Torblatt der eingangs beschriebenen Art zur Verfügung zu stellen, mit dem unter Sicherstellung einer hohen Betriebszuverlässigkeit zuverlässig das Eindringen von Schmutz und Feuchtigkeit in die von der verformbaren Wand begrenzten Kammer verhindert werden kann.Given the problems in the prior art described above, the Invention, the object of a sealing element for a door leaf of the beginning to provide the type described, with ensuring a high Operational reliability reliably prevents dirt and moisture from entering the deformable wall limited chamber can be prevented.

Erfindungsgemäß wird diese Aufgabe durch eine Weiterbildung der bekannten Dichtungselemente gelöst, die im wesentlichen durch eine dem Auftreten von Überdrucken und Unterdrucken in der Kammer entegegenwirkende Druckausgleichseinrichtung gekennzeichnet ist. According to the invention, this object is achieved by developing the known Sealing elements solved, essentially by the occurrence of overpressures and negative pressure in the chamber counteracting pressure compensation device is.

Diese Erfindung geht auf die Erkenntnis zurück, daß die Beschädigungen der bekannten, an ihren axialen Enden verschlossenen Dichtungselemente in erster Linie darauf zurückzuführen sind, daß bei einer Schließbewegung des Torblattes insbesondere bei Auftreten von Bodenunebenheiten im Bereich der Hauptschließkante eine das Volumen der von der verformbaren Wand begrenzten Kammer stark verringernde Verformung dieser Kammer auftritt, die zu einem das Dichtungselement beschädigenden Überdruck in der Kammer führen kann. Mit der erfindungsgemäßen Weiterbildung der bekannten Dichtungselemente kann das Auftreten derartiger Drucke zuverlässig verhindert werden, um so eine Beschädigung des Dichtungselementes zu vermeiden. Darüber hinaus kann mit dieser Druckausgleichseinrichtung auch noch ein im Verlauf des Betriebs von Sektionaltoren möglicherweise auftretender Unterdruck in der von der verformbaren Wand begrenzten Kammer ausgeglichen werden. Dabei kann die Druckausgleichseinrichtung unabhängig von der sonstigen Form des Dichtungselement und/oder des damit ausgestatteten Torblattes gewählt werden, um so das Eindringen von Schmutz und Feuchtigkeit in die von der verformbaren Wand begrenzte Kammer zu verhindern.This invention is based on the knowledge that the damage to the known sealing elements sealed at their axial ends primarily thereon are due to the fact that in the case of a closing movement of the door leaf in particular Uneven floors in the area of the main closing edge represent the volume of the Chamber delimited by the deformable wall greatly reducing deformation of this Chamber occurs which leads to an overpressure in the sealing element which damages the sealing element Chamber can lead. With the development of the known sealing elements according to the invention the occurrence of such pressures can be reliably prevented so as to Avoid damaging the sealing element. In addition, with this Pressure compensation device may also be used during the operation of sectional doors negative pressure occurring in the chamber delimited by the deformable wall be balanced. The pressure compensation device can be independent of the other Shape of the sealing element and / or the door leaf equipped with it selected to prevent dirt and moisture from getting into the mold Prevent wall confined chamber.

Bei einer besonders bevorzugten Ausführungsform der Erfindung weist die Druckausgleichseinrichtung mindestens ein das Austreten von Luft aus der Kammer ermöglichendes Ventil und/oder eine die Kammer mit der Umgebung verbindende Leitung in Form eines Kanals, Schlauches und/oder Rohres auf, wobei diese Leitung zweckmäßigerweise luftund/oder feuchtigkeitsdicht in die Kammer oder eine mit der Kammer in Verbindung stehende weitere Kammer eingesetzt ist. Dabei kann das der Kammer bzw. der weiteren Kammer abgewandte Ende der Leitung an einer besonders geschützten Stelle angeordnet werden, um so das Eindringen von Schmutz und Feuchtigkeit in die Leitung und damit auch in die Kammer zu verhindern. Beispielsweise ist daran gedacht, an der Innenfläche des Torblattes einen geschützten Hohlraum, der beispielsweise durch eine Abzweigdose oder ähnliches gebildet sein kann, zur Verfügung zu stellen, in den die Leitung der Druckausgleichseinrichtung mündet. Zum dichtenden Einsetzen der Leitung in die Kammer und/oder die weitere Kammer kann bei einer bevorzugten Ausführungsform der Erfindung eine einerseits an einer äußeren Begrenzungsfläche der Leitung und andererseits an einer inneren Begrenzungsfläche der Kammer und/oder der weiteren Kammer anliegende Dichtmasse, insbesondere Vergußmasse eingesetzt werden. Zusätzlich oder alternativ dazu kann ein der Kammer zugewandtes Ende der Leitung auch in einem in die Kammer einsetzbaren Schließelement, insbesondere im Bereich der Mantelfläche eines dichtend in die Kammer einsetzbaren Gehäuses dieses Schließelementes vorgesehen sein.In a particularly preferred embodiment of the invention, the pressure compensation device at least one that allows air to escape from the chamber Valve and / or a line connecting the chamber with the environment in the form of a Channel, hose and / or pipe, this line expediently air and / or moisture-proof into the chamber or one connected to the chamber another chamber is inserted. This can be the chamber or the other chamber end of the line facing away from a specially protected location, so the penetration of dirt and moisture into the pipe and thus also into to prevent the chamber. For example, it is thought of on the inner surface of the door leaf a protected cavity, for example by a junction box or the like can be formed to provide in the line of the pressure compensation device empties. For sealing insertion of the line in the chamber and / or In a preferred embodiment of the invention, another chamber can be one hand on an outer boundary surface of the line and on the other hand on an inner boundary surface the chamber and / or the further chamber sealing compound, in particular Potting compound can be used. Additionally or alternatively, one of the End of the line facing the chamber also in an insertable into the chamber Closing element, in particular in the area of the outer surface of a seal in the chamber insertable housing of this closing element may be provided.

Bei Toren, bei denen das Torblatt mit einer Antriebseinrichtung in Form eines Motors, insbesondere Elektromotors, zwischen der Öffnungsstellung und Schließstellung bewegbar ist, muß die Bodendichtung im Bereich der Hauptschließkante so abgesichert werden, daß die Schließbewegung automatisch gestoppt wird, wenn diese Bodendichtung in Anlage an einen Gegenstand oder eine Person im Bereich der mit dem Torblatt zu verschließenden Wandöffnung gelangt. Zu diesem Zweck werden Schaltleisten, druckluftgesteuerte Membranen oder aber auch Optosensoren eingesetzt. Dabei hat sich der Einsatz von Optosensoren aus Kostengründen und im Hinblick auf die Funktionsfähigkeit als besonders günstig erwiesen. Derartige Optosensoren weisen einen Sender und einen Empfänger auf, die an einander entgegengesetzten Enden in die von der verformbaren Wand begrenzte Kammer des Dichtungselementes eingesetzt werden. Wenn das Dichtungselement im Verlauf der Torblattbewegung auf einen Gegenstand oder eine Person trifft, wird die verformbare Wand derartig verformt, daß sie den von dem Sender ausgehenden Strahl wie etwa einen Infrarotstrahl unterbricht. Diese Unterbrechung wird mit dem Empfänger erkannt und kann zur Steuerung des Antriebs bzw. zum Abstoppen der Torblattbewegung ausgenutzt werden. Derartige Anordnungen sind in der DE 94 18 885 U1 und der DE 197 47 830 A1 beschrieben.In the case of gates in which the door leaf has a drive device in the form of a motor, in particular electric motor, movable between the open position and the closed position , the floor seal in the area of the main closing edge must be secured so that the closing movement is automatically stopped when this floor seal comes into contact an object or person in the area of the door leaf to be locked Wall opening arrives. For this purpose, safety edges are controlled by compressed air Membranes or optosensors used. The use of Optosensors for reasons of cost and in terms of functionality as special proven favorable. Such optosensors have a transmitter and a receiver, the opposite ends into the one delimited by the deformable wall Chamber of the sealing element are used. If the sealing element in the If the movement of the door leaf meets an object or a person, the deformable wall deformed such that it like the beam emanating from the transmitter interrupts an infrared ray. This interruption is recognized by the receiver and can be used to control the drive or to stop the door leaf movement become. Such arrangements are in DE 94 18 885 U1 and DE 197 47 830 A1.

Allerdings muß bei Einsatz derartiger Optosensoren das Eindringen von Schmutz und Feuchtigkeit in die von der verfombaren Wand begrenzte Kammer besonders zuverlässig verhindert werden, weil ansonsten Funktionsstörungen des Senders und/oder Empfängers auftreten können. Wenn nun die von der verformbaren Wand begrenzte Kammer dicht verschlossen wird, treten in der Regel die eingangs beschriebenen Probleme auf. Daher kann die Erfindung mit besonderem Vorteil in Verbindung mit Dichtungselementen eingesetzt werden, die mit einem Optosensor der vorstehend beschriebenen Art ausgestattet sind. Dazu bildet die mit der Leitung in Verbindung stehende weitere Kammer und/oder ein Teil der Leitung selbst zweckmäßigerweise einen Bestandteil eines dichtend in die Kammer eingesetzten Gehäuses, in dem ein ggf. zusammen mit einem oder mehreren weiteren Elementen zum Erfassen einer Verformung der Kammer betreibbares Sensorelement, insbesondere in Form eines Senders oder Empfängers eines Optosensors aufgenommen ist. Dabei ist zur Verwirklichung eines Druckausgleichs zweckmäßigerweise zwischen der äußeren Begrenzungsfläche des Sensorelementes und der inneren Begrenzungsfläche des Gehäuses und/oder in dem Gehäuse selbst und/oder in dem Sensorelement selbst ein ggf. über weitere Verbindungselemente einerseits mit der Kammer und andererseits mit einem der Kammer abgewandten Teil der Leitung in Verbindung stehender Kanal vorgesehen. Dieser Kanal wird zweckmäßigerweise von mindestens einem sich zwischen dem Gehäuse und dem Sensorelement erstreckenden Abstandhalter begrenzt. In besonders vorteilhafter Ausgestaltung der Erfindung wird der Kanal von mindestens einem vorzugsweise in eine entsprechende Ausnehmung in der äußeren Begrenzungsfläche eingreifenden Positionierungselement begrenzt. Dabei kann bei Einsatz eines im wesentlichen zylindermantelförmigen Gehäuses und eines kreiszylindrischen Sensorelementes mit Hilfe der Abstandhalter eine koaxiale Ausrichtung des Sensorelementes und des Gehäuses sichergestellt werden, während mit Hilfe des Positionierungselementes eine Verdrehung des Sensorelementes bezüglich dem Gehäuse verhindert werden kann.However, the penetration of dirt and Moisture in the chamber delimited by the deformable wall is particularly reliable can be prevented because otherwise malfunctions of the transmitter and / or receiver may occur. If the chamber delimited by the deformable wall is now tight is closed, the problems described at the beginning usually occur. Therefore the invention can be used with particular advantage in connection with sealing elements be equipped with an optosensor of the type described above. For this purpose, the further chamber and / or a part connected to the line forms the line itself expediently a part of a seal in the chamber used housing, in which a possibly together with one or more others Elements for detecting a deformation of the chamber operable sensor element, in particular in the form of a transmitter or receiver of an optosensor. It is expedient to achieve pressure equalization between the outer boundary surface of the sensor element and the inner boundary surface of the Housing and / or in the housing itself and / or in the sensor element itself a possibly via further connecting elements on the one hand with the chamber and on the other hand with a part of the line facing away from the chamber is provided in the connecting channel. This channel is expediently located between at least one between the housing and the spacer extending the sensor element limited. In a particularly advantageous way Embodiment of the invention, the channel of at least one is preferably in one corresponding recess in the outer limiting surface engaging positioning element limited. When using an essentially cylindrical jacket Housing and a circular cylindrical sensor element using the spacers ensure a coaxial alignment of the sensor element and the housing, while with the help of the positioning element a rotation of the sensor element can be prevented with respect to the housing.

Alternativ oder zusätzlich kann dieser Kanal von einer zweckmäßigerweise mit einem Abdeckelement abgedeckten Einbuchtung in der Mantelfläche des Gehäuses gebildet sein.As an alternative or in addition, this channel can expediently be provided with a a cover element formed recess in the lateral surface of the housing his.

Wenngleich auch an den Einsatz von batteriebetriebenen und drahtlos arbeitenden Sensorelementen gedacht ist, kann das Sensorelement auch mit mindestens einem dichtend in die Kammer und/oder das Gehäuse eingesetzten Versorgungs- und/oder Signalkabel ausgestattet sein. Dabei kann dieses Kabel völlig getrennt von der Leitung der Druckausgleichseinrichtung geführt sein. Bei einer besonders bevorzugten Ausführungsform der Erfindung bildet die Leitung jedoch eine Führung für das Versorgungs- und/oder Signalkabel.Although also on the use of battery-operated and wireless ones Sensor elements is intended, the sensor element can also be sealed with at least one supply and / or signal cables used in the chamber and / or the housing be equipped. This cable can be completely separate from the line of the pressure compensation device be led. In a particularly preferred embodiment of the Invention, however, the line is a guide for the supply and / or signal cable.

Wie der vorstehenden Erläuterung eines erfindungsgemäßen Dichtungselementes zu entnehmen ist, weist eine zur Herstellung eines derartigen Dichtungselementes benutzbare Druckausgleichseinrichtung mindestens eine die Kammer des Dichtungselementes mit der Umgebung verbindende Leitung auf.
