Description

Die Erfindung betrifft Tore nach dem Oberbegriff des Patentanspruchs 1.The invention relates to gates according to the preamble of patent claim 1.

Derartige Tore können in Form von sogenannten Sektionaltoren verwirklicht sein, bei denen das Torblatt in der Öffnungsstellung über Kopf etwa in einer Horizontalebene angeordnet ist. Das Torblatt besteht bei derartigen Sektionaltoren aus einer Mehrzahl von bezüglich senkrecht zu der vorgegebenen Bahn verlaufenden Gelenkachsen gelenkig miteinander verbundenen Torblattelementen. Dadurch wird eine Torblattbewegung ermöglicht, bei der das Torblatt einen bogenförmigen Abschnitt der vorgegebenen Bahn durchläuft.Such gates can be realized in the form of so-called sectional gates, in which the gate leaf is arranged overhead in the open position approximately in a horizontal plane. In such sectional doors, the door leaf consists of a plurality of door leaf elements which are connected to one another in an articulated manner with respect to joint axes running perpendicularly to the predetermined path. This enables a door leaf movement in which the door leaf runs through an arcuate section of the specified path.

Bei einer anderen Ausführungsform von Toren der eingangs beschriebenen Art ist das Torblatt in der Öffnungsstellung zu einem mehrlagigen Wickel aufgewickelt. Bei derartigen Rolltoren kann das Torblatt insgesamt aus einem biegsamen Material, wie etwa einer Kunststofffolie, gebildet sein. Zur Führung der Torblattbewegung können Führungsrollen zum Einsatz kommen, die an senkrecht zu den seitlichen Rändern des Torblatts verlaufenden Stabilisierungseinrichtungen angebracht sind. Dazu können die Stabilisierungseinrichtungen an im Bereich der seitlichen Ränder des Torblatts angeordnete und an dem Torblatt befestigte Gelenkanordnungen gekoppelt sein, die andererseits mit Führungsrollen zur Führung der Torblattbewegung ausgestattet sein können. Derartige Tore sind in der EP 3 176 355 B1 angegeben. Rolltore, bei denen das Torblatt in der Öffnungsstellung oberhalb der Wandöffnung einen mehrlagigen Wickel bildet, können auch in Form von sogenannten Schnelllauftoren verwirklicht sein, bei denen das Torblatt ähnlich wie bei Sektionaltoren aus einer Mehrzahl von bezüglich senkrecht zu der vorgegebenen Bahn verlaufenden Gelenkachsen gelenkig miteinander verbundenen Torblattelementen besteht, deren Höhe in Richtung der vorgegebenen Bahn allerdings deutlich geringer ist als bei Sektionaltoren. Derartige Tore sind beispielsweise in der DE 10 2009 017 767 A1 beschrieben. Bei allen vorstehend erläuterten Toren werden zur Führung der Torblattbewegung üblicherweise an dem Torblatt angebrachte und bezüglich senkrecht zu der vorgegebenen Bahn und etwa parallel zu der Torblattebene in der Schließstellung verlaufenden Rollenachsen drehbar gelagerte Führungsrollen eingesetzt, die in feststehend angeordneten Führungsschienen aufgenommen sind, wobei der Verlauf der Führungsschienen die vorgegebene Bahn bestimmt. Bei Einsatz der gerade beschriebenen Tore kommt es insbesondere bei hohen Geschwindigkeiten der Torblattbewegung, also bei sogenannten Schnelllauftoren, häufig zu einer beachtlichen Geräuschentwicklung. Ferner wird eine große mechanische Beanspruchung der Führungsanordnung beobachtet.In another embodiment of gates of the type described above, the gate leaf is wound up into a multi-layer coil in the open position. In the case of such roller doors, the door leaf can be formed entirely from a flexible material, such as a plastic film. To guide the movement of the door leaf, guide rollers can be used, which are attached to stabilizing devices running perpendicularly to the lateral edges of the door leaf. For this purpose, the stabilizing devices can be coupled to joint arrangements arranged in the area of the lateral edges of the door leaf and fastened to the door leaf, which on the other hand can be equipped with guide rollers for guiding the movement of the door leaf. Such gates are in the EP 3 176 355 B1 specified. Roller doors, in which the door leaf forms a multi-layer roll above the wall opening in the open position, can also be implemented in the form of so-called high-speed doors, in which the door leaf, similar to sectional doors, consists of a plurality of articulated axes running perpendicular to the specified path connected door leaf elements, the height of which in the direction of the specified track is, however, significantly lower than in the case of sectional doors. Such goals are for example in the DE 10 2009 017 767 A1 described. In all the doors explained above, to guide the movement of the door leaf, guide rollers are usually attached to the door leaf and rotatably mounted with respect to the roller axes running perpendicular to the specified path and approximately parallel to the plane of the door leaf in the closed position and are accommodated in fixed guide rails, with the course of the Guide rails determines the given path. When the doors just described are used, considerable noise is often generated, particularly at high speeds of door leaf movement, that is to say in the case of so-called high-speed doors. Furthermore, a large mechanical stress on the guide arrangement is observed.

In der DE 3619516 , der US 2010/251622 A1 und der EP 1241310 A1 sind Schiebetore mit horizontal verlaufenden Bodenschienen offenbart. Tore nach dem Oberbegriff des Patentanspruchs 1 sind in der EP 2835490 A2 angegeben.In the UK 3619516 , the U.S. 2010/251622 A1 and the EP 1241310 A1 discloses sliding gates with horizontally extending bottom rails. Goals according to the preamble of claim 1 are in the EP 2835490 A2 specified.

Angesichts der vorstehend beschriebenen Probleme im Stand der Technik liegt der Erfindung die Aufgabe zugrunde, mit geringer Geräuschentwicklung verschleißarm bewegbare Tore bereitzustellen.In view of the above-described problems in the prior art, the invention is based on the object of providing low-wear movable gates with low noise development.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebene Weiterbildung von Toren der eingangs genannten Art gelöst.According to the invention, this object is achieved by the development of gates of the type mentioned in the characterizing part of claim 1.

Die Montage erfindungsgemäßer Tore kann unter Einhaltung der geforderten Maßgenauigkeit vereinfacht werden, wenn zwei Führungseinrichtungen, die in montiertem Zustand den Führungssteg zwischen sich aufnehmen und einen Führungssatz bilden, an einem gemeinsamen Träger gelagert sind, wobei der gemeinsame Träger vorzugsweise auf seiner den Führungseinrichtungen abgewandten Seite lösbar an dem Torblatt angebracht sein kann. Diese Anordnung ermöglicht den Einsatz vormontierter Baugruppen, bestehend aus Träger und Führungseinrichtungen, die ohne Änderung des Abstands zwischen den Führungseinrichtungen, insbesondere zwischen den Rollenachsen der Führungsrollen an dem Torblatt angebracht werden kann.The assembly of goals according to the invention can be simplified while maintaining the required dimensional accuracy if two guide devices, which in the assembled state receive the guide web between them and form a guide set, are mounted on a common carrier, the common carrier preferably being detachable on its side facing away from the guide devices can be attached to the door leaf. This arrangement enables the use of pre-assembled assemblies, consisting of carrier and guide devices, which can be attached to the door leaf without changing the distance between the guide devices, in particular between the roller axes of the guide rollers.

Wenn die vorgegebene Bahn einen bogenförmigen Abschnitt aufweist, hat es sich in diesem Fall als besonders zweckmäßig erwiesen, wenn der Träger bezüglich einer ggf. parallel zu den Rollenachsen verlaufenden Drehachse drehbar und/oder bezüglich einer ggf. parallel zu der Rollenachse verlaufenden Translationsachse verschiebbar an dem Torblatt angebracht ist. Dadurch können Montageungenauigkeiten kompensiert werden. Eine solche Anbringung kann fertigungstechnisch besonders einfach verwirklicht werden, wenn zur Anbringung des gemeinsamen Trägers an dem Torblatt ein Befestigungselement, in Form eines Befestigungsbolzens und ein Befestigungselement in Form einer zur Aufnahme des Befestigungsbolzens ausgelegten, vorzugsweise in Form einer Hülse ausgeführten Aufnahme ausgeführt ist, wobei ein Befestigungselement am Träger und ein Befestigungselement am Torblatt angeordnet ist.If the specified path has an arcuate section, it has proven to be particularly expedient in this case if the carrier can be rotated with respect to an axis of rotation that may be parallel to the roller axes and/or with respect to a possibly parallel to the Roll axis extending translation axis is slidably mounted on the door leaf. This allows assembly inaccuracies to be compensated. Such an attachment can be realized in a particularly simple manner in terms of production if, for attaching the common support to the door leaf, a fastening element is designed in the form of a fastening bolt and a fastening element is designed in the form of a receptacle designed to receive the fastening bolt, preferably in the form of a sleeve, with a Fastening element is arranged on the carrier and a fastening element on the door leaf.

Bei erfindungsgemäßen Toren kann die Torblattbewegung unter weiterer Reduzierung der Geräuschentwicklung und des mechanischen Verschleißes weiter stabilisiert werden, wenn ein zwischen den Führungseinrichtungen angeordnetes und vorzugsweise an dem gemeinsamen Träger befestigtes Gleitstück vorgesehen ist, das an eine zwischen den Führungsflächen angeordnete Gleitfläche des Führungsstegs anlegbar ist. Auf diese Weise kann einem Versatz des Torblatts durch Anlage des Gleitstücks an die Anlagefläche entgegengewirkt werden. Dazu sind vorzugsweise im Bereich der einander entgegengesetzten seitlichen Ränder des Torblatts Gleitstücke vorgesehen, die an Gleitflächen der im Bereich dieser seitlichen Ränder angeordneten Führungsstege anlegbar sind. Das Torblatt ist dann zwischen den Führungsstegen aufgenommen und wird an einer Bewegung in einer senkrecht zu der vorgegebenen Bahn verlaufenden Richtung einerseits durch die zwischen den Führungseinrichtungen aufgenommenen Führungsstege und andererseits durch die in Anlage an die Gleitflächen der Führungsstege gelangenden Gleitstücke gehindert.In the case of doors according to the invention, the movement of the door leaf can be further stabilized, with a further reduction in noise development and mechanical wear, if a sliding piece is provided which is arranged between the guide devices and is preferably fastened to the common carrier, and which can be placed against a sliding surface of the guide web which is arranged between the guide surfaces. In this way, an offset of the door leaf can be counteracted by the sliding piece being in contact with the contact surface. For this purpose, sliding pieces are preferably provided in the area of the opposite lateral edges of the door leaf, which can be placed on sliding surfaces of the guide webs arranged in the area of these lateral edges. The door leaf is then accommodated between the guide webs and is prevented from moving in a direction perpendicular to the predetermined path on the one hand by the guide webs accommodated between the guide devices and on the other hand by the sliding pieces coming into contact with the sliding surfaces of the guide webs.

Die Erfindung kann mit besonderem Vorteil bei Toren eingesetzt werde, bei denen im Bereich der in der Schließstellung etwa in Schwererichtung verlaufenden seitlichen Ränder des Torblatts Gelenkanordnungen vorgesehen sind, von denen jede eine Mehrzahl von bezüglich senkrecht zu den seitlichen Rändern und etwa parallel zur Torblattebene verlaufenden Gelenkachsen gelenkig miteinander verbundenen Gelenkglieder aufweist. Bei dieser Ausführungsform kann an mindestens einem, vorzugsweise an jedem Gelenkglied ein Träger mit zwei Führungseinrichtungen derart angebracht sein, dass die Führungseinrichtungen auf der dem Torblatt abgewandten Seite des Gelenkglieds angeordnet sind und der Führungssteg zwischen den Führungseinrichtungen angeordnet ist.The invention can be used with particular advantage in doors in which articulation arrangements are provided in the area of the lateral edges of the door leaf running approximately in the direction of gravity in the closed position, each of which has a plurality of articulation axes running perpendicularly to the lateral edges and approximately parallel to the plane of the door leaf has articulated interconnected joint members. In this embodiment, a carrier with two guide devices can be attached to at least one, preferably to each joint member such that the guide devices are arranged on the side of the joint member facing away from the door leaf and the guide web is arranged between the guide devices.

Das Torblatt selbst kann eine Mehrzahl von bezüglich senkrecht zu der vorgegebenen Bahn verlaufenden Gelenkachsen gelenkig miteinander verbundenen Torblattgliedern aufweisen. Dabei können die Torblattglieder über gesonderte Gelenke miteinander verbunden sein. Zusätzlich oder alternativ ist aber auch daran gedacht, die Torblattglieder mit Hilfe der im Bereich der seitlichen Ränder des Torblatts angebrachten Gelenkanordnungen gelenkig miteinander zu verbinden.The door leaf itself can have a plurality of door leaf elements connected to one another in an articulated manner with respect to joint axes running perpendicularly to the predetermined path. The door leaf elements can be connected to one another via separate joints. In addition or as an alternative, however, it is also possible to use the in the area to connect the lateral edges of the door leaf attached joint assemblies in an articulated manner.

Die Torblattglieder können eine ein Isoliermaterial, wie etwa Polyurethanschaum, enthaltende Schale aufweisen. Die Metallschale kann beispielsweise durch Kaltumformen von Metallbändern hergestellt werden. Das Isoliermaterial kann zwischen einer eine äußere Begrenzungsfläche des Torblattglieds bildenden äußeren Metallschale und einer eine innere Begrenzungsfläche des Torblattglieds bildenden inneren Schale aufgenommen sein. Das Isoliermaterial kann den Hohlraum zwischen den beiden Schalen des Torblattglieds im Wesentlichen vollständig ausfüllen.The door leaf members may have a shell containing an insulating material such as polyurethane foam. The metal shell can be produced, for example, by cold forming metal strips. The insulating material may be sandwiched between an outer metal shell forming an outer perimeter of the door leaf member and an inner shell forming an inner perimeter of the door leaf member. The insulating material can essentially completely fill the cavity between the two shells of the door leaf member.

Zusätzlich oder alternativ zu gelenkig miteinander verbundenen Torblattgliedern kann das Torblatt erfindungsgemäßer Tore zumindest abschnittweise aus einem biegsamen Material, wie etwa einer Kunststofffolie, gebildet sein. In diesem Fall können die Gelenkanordnungen über senkrecht zu den seitlichen Rändern des Torblatts verlaufende Stabilisierungsanordnungen an die Gelenkanordnungen gekoppelt sein, wie in der EP 3 176 355 B1 angegeben.In addition or as an alternative to the door leaf members that are connected to one another in an articulated manner, the door leaf of the doors according to the invention can be formed at least in sections from a flexible material, such as a plastic film. In this case, the joint arrangements can be coupled to the joint arrangements via stabilizing arrangements running perpendicularly to the lateral edges of the door leaf, as in FIG EP 3 176 355 B1 specified.

Der erste Gesichtspunkt der Erfindung betrifft sogenannte Rolltore, bei denen das Torblatt in der Öffnungsstellung einen mehrlagigen Wickel bildet. Bei derartigen Toren weist der Führungssteg einen vorzugsweise etwa in Schwererichtung verlaufenden und sich in der Schließstellung etwa parallel zu den seitlichen Rändern des Torblatts erstreckenden geradlinig verlaufenden Abschnitt auf, der an seinem oberen Ende in einen spiralförmig umlaufenden Abschnitt übergeht. Dabei sind zweckmäßigerweise zwei im Bereich der einander entgegengesetzten seitlichen Ränder angeordnete Führungsstege vorgesehen.The first aspect of the invention relates to so-called roll-up doors, in which the door leaf forms a multi-layer coil in the open position. In gates of this type, the guide bar has a rectilinear section that preferably runs approximately in the direction of gravity and in the closed position extends approximately parallel to the lateral edges of the door leaf, which transitions at its upper end into a spirally circumferential section. In this case, two guide webs arranged in the region of the mutually opposite lateral edges are expediently provided.

Im Rahmen der Erfindung wird die Torblattbewegung zumindest längs eines Abschnitts der vorgegebenen Bahn im Bereich mindestens eines der seitlichen Ränder des Torblatts geführt. Zu diesem Zweck weist mindestens eine Führungseinrichtung eine torblattseitige Magnetfelderzeugungseinrichtung auf und dem Führungssteg ist mindestens eine stegseitige Magnetfelderzeugungseinrichtung zugeordnet, wobei die Magnetfelderzeugungseinrichtungen zum Erhalt einer berührungsfreien Führung der Torblattbewegung längs mindestens eines Abschnitts der vorgegebenen Bahn im Bereich mindestens eines der einander entgegengesetzten seitlichen Ränder ausgelegt sind.Within the scope of the invention, the movement of the door leaf is guided at least along a section of the specified path in the area of at least one of the lateral edges of the door leaf. For this purpose, at least one guide device has a magnetic field generating device on the door leaf side, and at least one magnetic field generating device on the web side is assigned to the guide bar, the magnetic field generating devices being designed to obtain contact-free guidance of the door leaf movement along at least one section of the specified path in the area of at least one of the opposite lateral edges.

Dabei können auf einander entgegengesetzten Seiten des Führungsstegs mit mindestens einer Führungsfläche, in deren Bereich ein Magnetfeld erzeugt wird, zusammenwirkende torblattseitige Magnetfelderzeugungseinrichtungen vorgesehen sein, welche entweder in attraktive oder in repulsive Wechselwirkung mit der stegseitigen Magnetfelderzeugungseinrichtung treten können.In this case, on mutually opposite sides of the guide bar, interacting door leaf-side guide surfaces can have at least one guide surface in the area of which a magnetic field is generated Magnetic field generating devices may be provided, which can either interact attractively or in repulsive interaction with the web-side magnetic field generating device.

Im Rahmen der Erfindung ist an Führungseinrichtungen gedacht, die ausschließlich aus in geeigneter Weise ansteuerbaren Elektromagneten bestehen. Aus konstruktiven Gründen hat es sich allerdings als vorteilhaft erwiesen, wenn mindestens eine Magnetfelderzeugungseinrichtung, vorzugsweise mindestens eine torblattseitige, das heißt mit dem Torblatt bewegbare, Magnetfelderzeugungseinrichtung, mindestens einen Permanentmagneten aufweist.Within the scope of the invention, guide devices are envisaged that consist exclusively of electromagnets that can be controlled in a suitable manner. For design reasons, however, it has proven to be advantageous if at least one magnetic field generating device, preferably at least one magnetic field generating device on the door leaf side, ie movable with the door leaf, has at least one permanent magnet.

Bei einer bevorzugten Ausführungsform der Erfindung weist die torblattseitige Magnetfelderzeugungseinrichtung zwei auf einander entgegengesetzten Seiten des Führungsstegs angeordnete Permanentmagneten auf, die an einem gemeinsamen, einen torblattseitigen Rand des Führungsstegs übergreifenden Träger festgelegt sind. Eine besonders zuverlässige berührungsfreie Führung kann mit dieser Anordnung von Permanentmagneten erreicht werden, wenn die magnetischen Feldlinien innerhalb der an dem Halter festgelegten Permanentmagneten in etwa gleicher Richtung und etwa senkrecht zu dem Torblatt verlaufen und der Träger zumindest teilweise aus einem ferromagnetischen Material, insbesondere weichmagnetischen Material, besteht.In a preferred embodiment of the invention, the magnetic field generation device on the door leaf side has two permanent magnets which are arranged on opposite sides of the guide web and are fixed to a common carrier that engages over an edge of the guide web on the door leaf side. A particularly reliable non-contact guide can be achieved with this arrangement of permanent magnets if the magnetic field lines within the permanent magnets fixed to the holder run in approximately the same direction and approximately perpendicular to the door leaf and the carrier is at least partially made of a ferromagnetic material, in particular soft magnetic material. consists.

Dabei sind ungleichnamige Pole der auf einander entgegengesetzten Seiten des Führungsstegs angeordneten torblattseitigen Permanentmagneten einander zugewandt. In dem Spalt zwischen den ungleichnamigen Polen wird ein Magnetfeld erhalten, welches durch Rückführung der Feldlinien in den ferromagnetischen Halter besonders stark ausgebildet werden kann. Wenn innerhalb des zwischen den ungleichnamigen Polen der torblattseitigen Permanentmagnete eine stegseitige Magnetfelderzeugungsanordnung, wie etwa stegseitige Permanentmagneten mit geeigneter Polung angeordnet sind, werden die torblattseitigen Permanentmagneten in einander entgegengesetzten Richtungen von den stegseitigen Permanentmagneten abgestoßen und es wird eine zuverlässige berührungsfreie Führung erreicht. Bei einer Auslenkung des Torblatts von der vorgegebenen Bahn in einer senkrecht zur Torblattebene verlaufenden Richtung verstärken sich die repulsiven Kräfte im Bereich mindestens eines torblattseitigen Permanentmagneten, so dass dem Kontakt zwischen torblattseitigen und stegseitigen Magnetfelderzeugungsanordnungen wirkungsvoll entgegengewirkt werden kann.Opposite poles of the permanent magnets on the door leaf side, which are arranged on opposite sides of the guide web, face each other. A magnetic field is obtained in the gap between the opposite poles, which can be made particularly strong by returning the field lines to the ferromagnetic holder. If a web-side magnetic field generation arrangement, such as web-side permanent magnets with suitable polarity, is arranged between the opposite poles of the permanent magnets on the door leaf side, the permanent magnets on the door leaf side are repelled in opposite directions from the permanent magnets on the web side and reliable non-contact guidance is achieved. If the door leaf is deflected from the specified path in a direction perpendicular to the plane of the door leaf, the repulsive forces in the area of at least one permanent magnet on the door leaf increase, so that the contact between the magnetic field generation arrangements on the door leaf and web side can be counteracted effectively.

Eine weiter Absicherung der Führung der Torblattbewegung kann erreicht werden, wenn auf der dem Torblatt abgewandten Seite der torblattseitigen Magnetfelderzeugungsanordnungen auch noch an die Führungsflächen anlegbare Führungsrollen, Führungsstifte, oder dergleichen mechanische Führungseinrichtungen angeordnet sind. Zusätzliche Führungsrollen können bezüglich etwa parallel zum Torblatt und senkrecht zu der vorgegebenen Bahn verlaufenden Rollenachsen drehbar am Torblatt gelagert sein. Dabei können auf einander entgegengesetzten Seiten des Führungsstegs mechanische Führungseinrichtungen, wie etwa Führungsrollen, angeordnet sein, welche bei einer besonders großen Kraftbeaufschlagung in einer senkrecht zur Torblattebene verlaufenden Richtung in Anlage an die entsprechende Führungsfläche gelangen, während sie bei der gewünschten berührungslosen Führung mit Abstand von den Führungsflächen angeordnet sind. Bei dieser Anordnung ist der Führungssteg also einerseits zwischen den torblattseitigen Magnetfelderzeugungsanordnungen und andererseits auch zwischen den am Torblatt angebrachten mechanischen Führungseinrichtungen, wie etwa den drehbar gelagerten Führungsrollen und/oder den Führungsstiften, angeordnet. Bei anderen Ausführungsformen der Erfindung können die Führungsrollen, Führungsstifte oder dergleichen auch auf der dem Torblatt zugewandten Seite der torblattseitigen Magnetfelderzeugungseinrichtungen angeordnet sein.The guidance of the door leaf movement can be further safeguarded if guide rollers, guide pins or similar mechanical guide devices that can be placed on the guide surfaces are also arranged on the side of the magnetic field generating arrangements on the door leaf side facing away from the door leaf. Additional guide rollers can be rotatably mounted on the door leaf with respect to roller axes running approximately parallel to the door leaf and perpendicular to the predetermined path. Mechanical guide devices, such as guide rollers, can be arranged on opposite sides of the guide web, which come into contact with the corresponding guide surface when a particularly large force is applied in a direction running perpendicular to the plane of the door leaf, while they move at a distance from the Guide surfaces are arranged. In this arrangement, the guide web is arranged on the one hand between the magnetic field generation arrangements on the door leaf side and on the other hand also between the mechanical guide devices attached to the door leaf, such as the rotatably mounted guide rollers and/or the guide pins. In other embodiments of the invention, the guide rollers, guide pins or the like can also be arranged on the side of the magnetic field generating devices on the door leaf side that faces the door leaf.

Die stegseitigen Magnetfelderzeugungseinrichtungen können besonders einfach montiert werden, wenn in mindestens einer Führungsfläche eine sich zumindest längs eines Abschnitts der vorgegebenen Bahn erstreckende Nut vorgesehen ist, in der eine stegseitige Magnetfelderzeugungseinrichtung zumindest teilweise aufgenommen sein kann. Die stegseitige Magnetfelderzeugungseinrichtung kann dabei als Permanentmagnet ausgeführt sein. Besonders vorteilhaft ist es bei dieser Anordnung, wenn die stegseitige Magnetfelderzeugungseinrichtung zumindest teilweise aus einem Elastomermagneten gebildet ist. Bei einem Elastomermagnet handelt es sich um einen Elastomer, in den hartmagnetische Materialien eingebettet sind. Die in der Nut aufgenommene Magnetfelderzeugungseinrichtung kann auf der dem Nutboden abgewandten Seite auch aus der Nut herausragen.The web-side magnetic field generating devices can be installed particularly easily if a groove is provided in at least one guide surface that extends at least along a section of the predetermined path and in which a web-side magnetic field generating device can be at least partially accommodated. The web-side magnetic field generation device can be designed as a permanent magnet. In this arrangement, it is particularly advantageous if the magnetic field generating device on the web side is formed at least partially from an elastomer magnet. An elastomer magnet is an elastomer in which hard magnetic materials are embedded. The magnetic field generating device accommodated in the groove can also protrude out of the groove on the side facing away from the groove bottom.

Bei allen Ausführungsformen der Erfindung mit stegseitigen und/oder torblattseitigen Magnetfelderzeugungseinrichtungen hat es sich als zweckmäßig erwiesen, wenn dem Führungssteg und/oder dem Torblatt eine Reinigungseinrichtung zugeordnet ist, wobei mit der stegseitigen Reinigungseinrichtung die torblattseitigen Magnetfelderzeugungseinrichtungen gereinigt werden können, und mit der torblattseitigen Reinigungseinrichtung die stegseitigen Magnetfelderzeugungseinrichtungen gereinigt werden können. Die Reinigungseinrichtungen können beispielsweise in Form von Reinigungsbürsten verwirklicht sein.In all embodiments of the invention with magnetic field generating devices on the web side and/or the door leaf side, it has proven to be expedient if a cleaning device is assigned to the guide web and/or the door leaf, with the cleaning device on the web side being able to clean the magnetic field generating devices on the door leaf side, and the cleaning device on the door leaf side being able to clean the web-side magnetic field generating devices can be cleaned. The cleaning devices can be implemented, for example, in the form of cleaning brushes.

Wenn die vorgegebene Bahn einen Übergang zwischen einem im Wesentlichen geradlinig verlaufenden Abschnitt und einem im Wesentlichen gekrümmt verlaufenden Abschnitt aufweist, wie etwa einen Übergang zwischen einem geradlinig verlaufenden Abschnitt und einem spiralförmig umlaufenden Abschnitt, hat es sich als besonders zweckmäßig erwiesen, wenn im Bereich dieses Übergangs eine stegseitige Magnetfelderzeugungseinrichtung zur Erzeugung besonders großer Felder vorgesehen ist, weil in diesem Übergangsbereich während der Torblattbewegung besonders große Kräfte auftreten, welche im Sinne einer berührungsfreien Führung durch entsprechend dimensionierte Magnetfelderzeugungseinrichtungen und deren Wechselwirkung mit den torblattseitigen Magnetfelderzeugungseinrichtungen aufgenommen werden sollten. Bei den zum Erzeugen besonders großer Felder ausgelegten stegseitigen Magnetfelderzeugungseinrichtungen kann es sich beispielsweise um gesinterte Hartmagneten handeln.If the predetermined path has a transition between a substantially rectilinear section and a substantially curved section, such as a transition between a rectilinear section and a helical circumferential section, it has proven to be particularly expedient if in the region of this transition a magnetic field generating device on the web side is provided for generating particularly large fields, because particularly large forces occur in this transition area during the movement of the door leaf, which should be absorbed in the sense of contact-free guidance by appropriately dimensioned magnetic field generating devices and their interaction with the magnetic field generating devices on the door leaf side. The web-side magnetic field generating devices designed to generate particularly large fields can be sintered hard magnets, for example.

Andererseits kann mindestens eine Magnetfelderzeugungseinrichtung, vorzugsweise mindestens eine stegseitige Magnetfelderzeugungseinrichtung, eine Elektromagnetanordnung aufweisen, der vorzugsweise eine Steuereinrichtung zugeordnet ist.On the other hand, at least one magnetic field generating device, preferably at least one web-side magnetic field generating device, can have an electromagnet arrangement, which is preferably assigned a control device.

Dabei ist auch daran gedacht, die Steuereinrichtung zum Erzeugen eines längs mindestens eines Abschnitts der vorgegebenen Bahn wandernden Magnetfeldes auszulegen. So kann ggf. nicht nur eine berührungsfreie Führung der Torblattbewegung, sondern auch ein die Torblattbewegung bewirkender Magnetantrieb verwirklicht werden.It is also contemplated that the control device should be designed to generate a magnetic field that travels along at least one section of the specified path. In this way, not only contact-free guidance of the movement of the door leaf can be implemented, but also a magnetic drive that effects the movement of the door leaf.

Zusätzlich oder alternativ ist auch daran gedacht, durch geeignete Ansteuerung des Elektromagneten bei Erreichen der Schließstellung eine attraktive Wechselwirkung zwischen den Magnetfelderzeugungseinrichtungen zu bewirken.In addition or as an alternative, consideration is also given to bringing about an attractive interaction between the magnetic field generating devices by suitably controlling the electromagnet when the closed position is reached.

Bei einer besonders bevorzugten Ausführungsform der Erfindung wird die Führung der Torblattbewegung mit torblattseitigen und stegseitigen Magnetfelderzeugungseinrichtungen erreicht, die vorzugsweise durch Permanentmagnete verwirklicht sind, wobei zusätzlich Elektromagnete vorgesehen sind, die bei Erreichen der Schließstellung eine attraktive Wechselwirkung mit den torblattseitigen Magnetfelderzeugungseinrichtungen bewirken, so dass durch Einschalten der entsprechenden Elektromagneten eine Dichtfunktion zwischen Torblatt und einem Rahmen bzw. einer Zarge hergestellt werden kann. Dabei werden vorzugsweise bistabile Anordnungen benutzt, bei denen die Dichtfunktion auch ohne Bestromung der Elektromagneten sichergestellt werden kann, während in der zweiten stabilen Lage eine berührungslose Führung mit Hilfe der Permanentmagneten ohne Bestromung der Elektromagneten sichergestellt werden kann.In a particularly preferred embodiment of the invention, the door leaf movement is guided with magnetic field generating devices on the door leaf and web side, which are preferably realized by permanent magnets, with additional electromagnets being provided which, when the closed position is reached, cause an attractive interaction with the magnetic field generating devices on the door leaf, so that by switching on of the corresponding electromagnets, a sealing function can be produced between the door leaf and a frame or frame. Bistable arrangements are preferably used in which the sealing function can be ensured without energizing the electromagnet, while in the second stable position non-contact guidance can be ensured using the permanent magnets without energizing the electromagnets.

Bei einem Verfahren zum Herstellen eines Tores mit Magnetfelderzeugungseinrichtungen hat es sich als besonders zweckmäßig erwiesen, wenn magnetisierbare Elemente, die zumindest teilweise aus hartmagnetischem Material bestehen, an dem Führungssteg und/oder dem Torblatt angebracht und erst danach magnetisiert werden. Dadurch wird eine Störung der Montage durch die attraktive Wechselwirkung der Permanentmagneten mit metallischen Bestandteilen des Tores vermieden.In a method for manufacturing a door with magnetic field generating devices, it has proven to be particularly expedient if magnetizable elements, which at least partially consist of hard magnetic material, are attached to the guide web and/or the door leaf and only then magnetized. This avoids disruption to the installation due to the attractive interaction of the permanent magnets with the metal components of the door.

Das in Fig. 1 dargestellte Tor umfasst ein insgesamt mit 10 bezeichnetes Torblatt und einen insgesamt mit 100 bezeichneten Führungssteg, wobei im Bereich beider seitlicher Ränder des Torblatts jeweils ein Führungssteg 100 vorgesehen ist, und das Torblatt 10 zwischen den Führungsstegen aufgenommen ist. Das Torblatt 10 besteht aus einer Mehrzahl von bezüglich einer senkrecht zu der durch den Führungssteg 100 vorgegebenen Bahn verlaufenden Richtung verlaufenden Gelenkachsen gelenkig miteinander verbundenen Torblattgliedern 12. Der Führungssteg 100 weist einen parallel zu den seitlichen Rändern des Torblatts 10 in der Schließstellung etwa in Schwererichtung verlaufenden Abschnitt 110 auf, der an seinem oberen Ende in einen spiralförmig umlaufenden Abschnitt 120 übergeht. Wie in Fig. 1 angedeutet, wird das Torblatt 10 in der Öffnungsstellung mit Hilfe des spiralförmigen Abschnitts 120 des Führungsstegs 100 zu einem mehrlagigen Wickel aufgewickelt. Zur Führung der Torblattbewegung sind an den seitlichen Rändern der Torblattglieder 12 angebrachte Führungsrollen 32 und 34 vorgesehen. Die Führungsrollen 32 und 34 bilden Führungsrollenpaare, zwischen denen der Führungssteg 100 aufgenommen ist.This in 1 The goal shown comprises a door leaf, generally designated 10, and a guide bar, generally designated 100, with a guide bar 100 being provided in the region of both lateral edges of the door leaf, and the door leaf 10 between the Guide bars is added. The door leaf 10 consists of a plurality of door leaf elements 12 which are connected to one another in an articulated manner with respect to a joint axis running perpendicularly to the direction specified by the guide bar 100. The guide bar 100 has a section which runs parallel to the lateral edges of the door leaf 10 in the closed position, approximately in the direction of gravity 110, which merges into a spirally encircling section 120 at its upper end. As in 1 indicated, the door leaf 10 is wound up in the open position with the aid of the spiral-shaped section 120 of the guide bar 100 to form a multi-layer coil. Guide rollers 32 and 34 are provided on the lateral edges of the door leaf members 12 to guide the movement of the door leaf. The guide rollers 32 and 34 form pairs of guide rollers between which the guide bar 100 is accommodated.

Die gelenkige Verbindung der Torblattglieder 12 erfolgt mit Hilfe von eine Mehrzahl von Gelenkgliedern 20 aufweisenden Gelenkanordnungen, wobei jedes Gelenkglied 20 auf eine Stirnfläche eines Torblattglieds 12 aufgesetzt ist. Die Führungsrollen 32 und 34 sind auf die Gelenkglieder 20 bzw. 22 derart aufgesetzt, dass sie auf der dem Torblatt abgewandten Seite der Gelenkglieder angeordnet sind. Das bei einer in der durch den Pfeil P angedeuteten Öffnungsbewegung nachlaufende Gelenkglied ist mit insgesamt vier Führungsrollen 32 und 34 ausgestattet, welche zwei Führungsrollenpaare bilden. Die Führungsrollen eines Führungsrollenpaars sind in einer senkrecht zu der durch den Führungssteg 100 verlaufenden Richtung voneinander beabstandet, wobei die Rollenachsen etwa parallel zueinander verlaufen. Der Führungssteg 100 weist einander entgegengesetzte äußere Begrenzungsflächen bzw. Führungsflächen 102 bzw. 104 auf, wobei eine erste Führungsrolle 32 jedes Führungsrollenpaars an eine erste Führungsfläche 102 des Führungsstegs 100 in Anlage gelangt und darauf abrollt, während eine zweite Führungsrolle 34 jedes Führungsrollenpaars an einer zweiten Führungsfläche 104 anliegt und darauf abrollt. Der Führungssteg ist so zwischen den Führungsrollen 32 und 34 der einzelnen Führungsrollenpaare angeordnet.The articulated connection of the door leaf elements 12 takes place with the aid of articulated arrangements having a plurality of articulated elements 20 , with each articulated element 20 being placed on an end face of a door leaf element 12 . The guide rollers 32 and 34 are placed on the joint members 20 and 22, respectively, in such a way that they are arranged on the side of the joint members facing away from the door leaf. The articulated member that follows in the opening movement indicated by the arrow P is equipped with a total of four guide rollers 32 and 34, which form two pairs of guide rollers. The guide rollers of a pair of guide rollers are spaced apart from one another in a direction perpendicular to the direction running through the guide bar 100, with the roller axes running approximately parallel to one another. The guide web 100 has opposite outer boundary surfaces or guide surfaces 102 and 104, with a first guide roller 32 of each pair of guide rollers coming into contact with a first guide surface 102 of the guide web 100 and rolling thereon, while a second guide roller 34 of each pair of guide rollers on a second guide surface 104 rests and rolls on it. The guide web is arranged between the guide rollers 32 and 34 of the individual pairs of guide rollers.

An dem bei einer Öffnungsbewegung nachlaufenden Rand des bei der Öffnungsbewegung nachlaufenden Torblattglieds ist eine Bodendichtung 14 angeordnet, die in der Schließstellung am Boden der mit dem Torblatt 10 zu verschließenden Wandöffnung anliegt. Wie in Fig. 1 dargestellt, können die Führungsrollen 32 und 34 der Führungsrollenpaare spielfrei an den Führungsflächen 102 und 104 des Führungsstegs anliegen.A bottom seal 14 is arranged on the edge of the gate leaf element that trails behind during an opening movement. As in 1 shown, the guide rollers 32 and 34 of the pairs of guide rollers can bear against the guide surfaces 102 and 104 of the guide bar without play.

Wie in Fig. 2 zu erkennen ist, sind an den beiden entgegengesetzten seitlichen Rändern des Torblatts 10 Führungsrollen 32 und 34 angeordnet, die mit im Bereich dieser seitlichen Ränder feststehend angebrachten, in Fig. 2 nicht dargestellten Führungsstegen 100 zusammenwirken.As in 2 can be seen, 10 guide rollers 32 and 34 are arranged on the two opposite lateral edges of the door leaf, with in the region of these lateral edges permanently attached, in 2 guide webs 100, not shown, interact.

In Fig. 3 ist die Montage eines Tors schematisch angedeutet. Die Führungsrollen 32 und 34 sind auf einem gemeinsamen Träger 40 bezüglich parallel zueinander und etwa senkrecht zu der vorgegebenen Bahn verlaufenden Rollenachsen drehbar gelagert. Die Rollenachsen der Führungsrollen 32 und 34 sind in einer senkrecht zu der vorgegebenen Bahn und senkrecht zu einer Hauptebene des Torblattglieds verlaufenden Richtung voneinander beabstandet. Der gemeinsame Träger 40 weist auf seiner den Führungsrollen 32 und 34 abgewandten Seite einen Befestigungsbolzen 42 auf, der sich in einer parallel zu den Rollenachsen verlaufenden Richtung erstreckt und in ein im Bereich eines auf eine Stirnfläche des Torblattglieds 12 aufgesetzten Gelenkglieds 20 vorgesehene Aufnahme 44 einführbar ist. Der Träger 40 wird auf diese insgesamt drehbar bezüglich dem Gelenkglied 20 und dem Torblattglied 12 gehalten. In axialer Richtung muss der Träger 40 nicht arretiert werden, weil an jedem seitlichen Rand des Torblattglieds 12 ein Träger vorgesehen ist und diese Träger 40 zusammen mit dem Torblattglied zwischen entsprechenden, feststehenden Führungsstegen 100 aufgenommen sind.In 3 the assembly of a gate is indicated schematically. The guide rollers 32 and 34 are rotatably mounted on a common carrier 40 with respect to roller axes running parallel to one another and approximately perpendicular to the predetermined path. The roller axes of the guide rollers 32 and 34 are spaced from each other in a direction perpendicular to the predetermined path and perpendicular to a principal plane of the door leaf member. On its side facing away from the guide rollers 32 and 34, the common support 40 has a fastening bolt 42, which extends in a direction parallel to the roller axes and can be inserted into a receptacle 44 provided in the region of a joint member 20 placed on an end face of the door leaf member 12 . The carrier 40 is held thereon in a generally rotatable manner with respect to the hinge member 20 and the door leaf member 12 . The carrier 40 does not have to be locked in the axial direction because a carrier is provided on each lateral edge of the door leaf member 12 and these carriers 40 are accommodated together with the door leaf member between corresponding fixed guide webs 100 .

Zur weiteren Reduzierung des axialen Spiels ist ein Gleitstück 50 vorgesehen, das zwischen den Führungsrollen 32 und 34 an Träger 40 angebracht werden kann. Bei einem bezüglich der Achse des Bolzens 42 parallelen Versatz der Gesamtanordnung, bestehend aus Torblattglied 12, Gelenkglied 20, Halter 40 und Führungsrollen 32 und 34, gelangt das Gleitstück 50 in Anlage an eine Gleitfläche des Führungsstegs 100, die zwischen den Führungsflächen 102 und 104 angeordnet ist, bzw. die Führungsflächen 102 und 104 des Führungsstegs 100 miteinander verbindet.To further reduce the axial play, a sliding piece 50 is provided, which can be attached to the carrier 40 between the guide rollers 32 and 34 . When the overall arrangement, consisting of door leaf element 12, articulated element 20, holder 40 and guide rollers 32 and 34, is offset parallel to the axis of bolt 42, sliding piece 50 comes into contact with a sliding surface of guide web 100, which is arranged between guide surfaces 102 and 104 is, or the guide surfaces 102 and 104 of the guide bar 100 connects to each other.

In Fig. 4 ist das Torblattglied 12 mit dem Träger 40 in montiertem Zustand dargestellt.In 4 the door leaf member 12 is shown with the carrier 40 in the assembled state.

Fig. 5 zeigt das in den Figuren 3 und 4 dargestellte Torblattglied nach der Montage zwischen den Führungsstegen 100. Es ist erkennbar, wie die Führungsrolle 32 an einer Führungsfläche 102 des Führungsstegs 100 anliegt. An der der Führungsfläche 102 entgegengesetzten Führungsfläche (nicht dargestellt) liegt die in Fig. 5 ebenfalls nicht dargestellte Führungsrolle 34 an. Der Führungssteg 100 kann weitgehend spielfrei zwischen den Führungsrollen 32 und 34 aufgenommen sein. Dadurch wird einerseits eine genaue Führung der Torblattbewegung erreicht und andererseits einer Geräuschentwicklung entgegengewirkt und die mechanische Belastung der Führungsanordnung reduziert. figure 5 shows that in the Figures 3 and 4 shown gate leaf element after assembly between the guide webs 100. It can be seen how the guide roller 32 bears against a guide surface 102 of the guide web 100. On the guide surface (not shown) opposite the guide surface 102 is the in figure 5 guide roller 34, also not shown. The guide web 100 can be accommodated between the guide rollers 32 and 34 largely without play. On the one hand, this achieves precise guidance of the door leaf movement and, on the other hand, counteracts the development of noise and reduces the mechanical load on the guide arrangement.

Die in Fig. 6 dargestellte Ausführungsform der Erfindung unterscheidet sich im Wesentlichen dadurch von den anhand der Figuren 1 bis 5 erläuterten Ausführungsformen, dass anstelle einer Rollenführung eine berührungsfreie Magnetführung der Torblattbewegung vorgesehen ist. Dazu ist das in Fig. 6 dargestellte Tor mit einer Magnetführungsanordnung 1000 ausgestattet, welche torblattseitige Magnetfelderzeugungseinrichtungen 1010 sowie stegseitige Magnetfelderzeugungseinrichtungen 1100 aufweist. Die torblattseitigen Magnetfelderzeugungseinrichtungen sind ähnlich wie die Führungsrollen auf einander entgegengesetzten Seiten des Führungsstegs 100 angeordnet. Die torblattseitige Magnetfelderzeugungseinrichtung ist aus Permanentmagneten gebildet, deren Feldlinien innerhalb der Magneten selbst parallel zur Torblattebene verlaufen. Ebenso ist die stegseitige Magnetfelderzeugungseinrichtung 1100 aus Permanentmagneten gebildet, deren Feldlinien ebenfalls innerhalb der Magneten selbst parallel zur Torblattebene verlaufen.In the 6 illustrated embodiment of the invention differs essentially from the basis of Figures 1 to 5 Explained embodiments that instead of a roller guide, a non-contact magnetic guide of the door leaf movement is provided. This is in 6 The door shown is equipped with a magnetic guide arrangement 1000, which has magnetic field generating devices 1010 on the door leaf side and magnetic field generating devices 1100 on the web side. Similar to the guide rollers, the magnetic field generating devices on the door leaf side are arranged on opposite sides of the guide web 100 . The magnetic field generating device on the door leaf side is formed from permanent magnets, the field lines of which run parallel to the plane of the door leaf within the magnets themselves. Likewise, the magnetic field generating device 1100 on the web side is formed from permanent magnets, the field lines of which also run within the magnets themselves parallel to the plane of the door leaf.

Die Anbringung der Permanentmagneten ist so gewählt, dass sich Bereiche gleicher Polung gegenüberliegen und damit abstoßende Kräfte zwischen stegseitiger Magnetfelderzeugungseinrichtung und torblattseitiger Magnetfelderzeugungseinrichtung wirken. Die Permanentmagneten einer einzelnen torblattseitigen Magnetfelderzeugungseinrichtung sind ähnlich wie die Führungsrollen an einem gemeinsamen Träger 1040 angebracht, so dass sie auf einander entgegengesetzten Seiten des Führungsstegs und der daran angebrachten stegseitigen Magnetfelderzeugungseinrichtung angeordnet sind. Die Polung der einzelnen Permanentmagneten ist besonders deutlich in Fig. 1c) zu erkennen. Zusätzlich ist ein seitlicher Positionierungsmagnet 1050 vorgesehen, welcher ebenfalls derart gepolt ist, dass eine repulsive Kraft zwischen dem torblattseitigen Positionierungsmagnet und der stegseitigen Magnetfelderzeugungseinrichtung hervorgerufen wird. Der Positionierungsmagnet 1050 übernimmt dieselbe Funktion wie das Gleitstück 50 in den anhand der Figuren 1 bis 5 erläuterten Ausführungsformen der Erfindung. Es ist auch daran gedacht, den Positionierungsmagnet durch ein Gleitstück zu ersetzen.The attachment of the permanent magnets is selected in such a way that areas of the same polarity are opposite one another and thus repelling forces act between the magnetic field generating device on the web side and the magnetic field generating device on the door leaf side. The permanent magnets of an individual magnetic field generating device on the door leaf side are attached to a common carrier 1040, similar to the guide rollers, so that they are arranged on opposite sides of the guide web and the web-side magnetic field generating device attached thereto. The polarity of the individual permanent magnets can be seen particularly clearly in FIG. 1c). In addition, a lateral positioning magnet 1050 is provided, which is also poled in such a way that a repulsive force is produced between the positioning magnet on the door leaf side and the magnetic field generating device on the web side. The positioning magnet 1050 performs the same function as the slider 50 in the basis of Figures 1 to 5 illustrated embodiments of the invention. Replacing the positioning magnet with a slider is also being considered.

In Fig. 6 zeigt Fig. 6b) das in Fig. 6a) gekennzeichnete Detail, Fig. 6c) das in Fig. 6b) gekennzeichnete Detail und Fig. 6d) eine Schnittdarstellung längs einer senkrecht zur Torblattbewegungsrichtung verlaufenden Schnittebene.In 6 shows Figure 6b ) this in Figure 6a ) marked detail, Figure 6c ) this in Figure 6b ) marked detail and Figure 6d ) a sectional view along a sectional plane running perpendicular to the direction of movement of the door leaf.

Die in Fig. 7 dargestellte Ausführungsform der Erfindung unterscheidet sich im Wesentlichen dadurch von der anhand Fig. 6 erläuterten Ausführungsform, dass die Feldlinien der einzelnen Magnetfelderzeugungseinrichtungen innerhalb der Permanentmagnete in einer senkrecht zur Torblattbewegungsrichtung verlaufenden Richtung verlaufen. Ferner ist anstelle eines Positionierungsmagnets ein Gleitstück 50 vorgesehen. In Fig. 7 werden zur Bezeichnung der einzelnen Bestandteile der Magnetführungsanordnung 1000 dieselben Bezugszeichen verwendet wie in Fig. 6.In the 7 illustrated embodiment of the invention essentially differs from the reference 6 Explained embodiment that the field lines of the individual magnetic field generating devices run within the permanent magnets in a direction perpendicular to the direction of movement of the door leaf. Furthermore, instead of a positioning magnet, a slider 50 is provided. In 7 the same reference numbers are used to designate the individual components of the magnet guide arrangement 1000 as in FIG 6 .

In Fig. 8 ist eine Kombination der berührungsfreien Magnetführung gemäß Fig. 7 mit einer Rollenführung gemäß den Figuren 1 bis 5 dargestellt. Eine Kombination aus Magnettechnik und Führungsrollentechnik kann vorteilhaft sein, wenn überdurchschnittliche Belastungen zu besorgen sind, die über die Rollen abgefangen werden können, ohne dass es zu einer Beschädigung der Magnetfelderzeugungseinrichtungen kommt. Ebenso ist es denkbar, dass die berührungslose Magnettechnik nur in einzelnen Abschnitten der Bewegungsbahn zum Einsatz kommt, wie etwa in den geradlinig verlaufenden Abschnitten, während eine mechanische Abstützung mit Hilfe der Führungsrollen 32 und 34 in gekrümmten Abschnitten der Führungsbahn, wie etwa im Bereich der spiralförmig umlaufenden Abschnitte zum Einsatz kommt.In 8 is a combination of non-contact magnetic guidance according to 7 with a roller guide according to Figures 1 to 5 shown. A combination of magnet technology and guide roller technology can be advantageous if there are concerns about above-average loads that can be absorbed by the rollers without damaging the magnetic field generating devices. It is also conceivable that the non-contact magnetic technology is only used in individual sections of the movement path, such as in the straight sections, while mechanical support using the guide rollers 32 and 34 is used in curved sections of the guide path, such as in the area of the spiral surrounding sections is used.

Bei der anhand der Fig. 9 erläuterten Ausführungsform der Erfindung ist die torblattseitige Magnetfelderzeugungseinrichtung 1010 sowie das Gleitstück 50 ebenso ausgebildet wie bei der anhand der Fig. 8 erläuterten Ausführungsform der Erfindung. Die stegseitige Magnetfelderzeugungseinrichtung ist allerdings in Form einer Elektromagnetanordnung 1200 ausgeführt. Ebenso wie bei der anhand der Fig. 8 erläuterten Ausführungsform ist ein Gleitstück 50 als Positionierungshilfe vorgesehen, wie es auch bei der anhand der Figuren 1 bis 5 erläuterten Ausführungsform der Erfindung der Fall ist. Bei einer Torblattbewegung kann die Elektromagnetanordnung 1200 mit Hilfe einer geeigneten Steuereinrichtung so betrieben werden, dass es zu einer repulsiven Kraft zwischen Elektromagnetanordnung und torblattseitigen Permanentmagneten kommt.When using the 9 Explained embodiment of the invention, the magnetic field generating device 1010 on the door leaf side and the slider 50 are designed in the same way as in the case of the reference to FIG 8 illustrated embodiment of the invention. However, the magnetic field generation device on the web side is designed in the form of an electromagnet arrangement 1200 . Just like with the based on the 8 illustrated embodiment, a slider 50 is provided as a positioning aid, as is also the case with the basis of Figures 1 to 5 illustrated embodiment of the invention is the case. When the door leaf moves, the electromagnet arrangement 1200 can be operated with the aid of a suitable control device in such a way that a repulsive force occurs between the electromagnet arrangement and the permanent magnets on the door leaf side.

Bei Erreichen der unteren Endlage kann die Elektromagnetanordnung entweder abgeschaltet oder mit umgekehrter Polung betrieben werden. Dadurch verschiebt sich das Torblatt in Richtung auf einen in einem Gehäuse 1300 vorgesehenen und vorzugsweise von einem dichtenden Material zumindest teilweise ummantelten Führungssteg, da der durch die vorherige Polung des Elektromagneten erzeugte Schwebezustand aufgehoben wird. Entweder reichen die repulsiven Kräfte der torblattseitigen Magnetfelderzeugungseinrichtung bzw. der torblattseitigen Permanentmagneten dann aus, um das Torblatt zu verschieben. Alternativ kann mit der Elektromagnetanordnung auch eine solche Polung erzeugt werden, dass eine attraktive Kraft zwischen torblattseitigen Permanentmagneten und stegseitiger Elektromagnetanordnung erreicht wird, die die gewünschte Verschiebung des Torblatts in einer zur Torblattbewegungsrichtung verlaufenden Richtung erzeugt.When the lower end position is reached, the electromagnet arrangement can either be switched off or operated with reversed polarity. As a result, the door leaf moves in the direction of a guide web provided in a housing 1300 and preferably at least partially encased by a sealing material, since the state of levitation created by the previous polarity of the electromagnet is eliminated. Either the repulsive forces of the magnetic field generating device on the door leaf side or of the permanent magnets on the door leaf side are then sufficient to move the door leaf. Alternatively, the electromagnet arrangement can also be used to generate such a polarity that an attractive force is generated between the permanent magnets on the door leaf side and the electromagnet arrangement on the web side is achieved, which produces the desired displacement of the door leaf in a direction running to the direction of movement of the door leaf.

Durch diese Verschiebung des Torblatts kann im geschlossenen Zustand eine verbesserte Dichtfunktion erreicht werden, wie in Fig. 9d) bei 1310 angedeutet. Wenn mit einer geeigneten Steuereinrichtung eine Torblattbewegung ausgelöst wird, wird die Polung der Elektromagnetanordnung wieder so umgestellt, dass der Schwebezustand erreicht und das Torblatt berührungsfrei geführt werden kann.By shifting the door leaf in this way, an improved sealing function can be achieved when it is closed, as shown in Figure 9d ) indicated at 1310. If a door leaf movement is triggered with a suitable control device, the polarity of the electromagnet arrangement is reversed again so that the floating state is achieved and the door leaf can be guided without contact.

Die in Fig. 10 dargestellte Ausführungsform der Erfindung entspricht im Wesentlichen der anhand der Fig. 8 erläuterten Ausführungsform. Sie unterscheidet sich dadurch von der anhand der Fig. 8 erläuterten Ausführungsform, dass die stegseitigen Magnetfelderzeugungseinrichtungen 1100 in einer sich in Längsrichtung des Führungsstegs erstreckenden Nut aufgenommen sind, wie besonders deutlich in den Fig. 10d) und 10f) erkennbar. Es ist weiter erkennbar, dass die stegseitigen Magnetfelderzeugungseinrichtungen 1100 auf ihrer dem Nutboden abgewandten Seite etwas über die Nut herausragen. Bei Herstellung der stegseitigen Magnetfelderzeugungseinrichtungen aus einem Elastomermagnet kann so eine zusätzliche Pufferfunktion erreicht werden. Zur Gewährleistung eines zufriedenstellenden Notlaufs sind bei der in Fig. 10 dargestellten Ausführungsform der Erfindung ähnlich wie bei der anhand der in Fig. 8 erläuterten Ausführungsform auf der dem Torblatt abgewandten Seite der Magnetfelderzeugungseinrichtungen 1010 und 1100 Führungsrollen 32 und 34 vorgesehen. Derartige ergänzende mechanische Führungseinrichtungen in Form von Führungsrollen, Führungsstiften, Führungsbolzen oder dergleichen können bei allen Ausführungsformen der Erfindung vorgesehen sein.In the 10 illustrated embodiment of the invention corresponds essentially to the basis of 8 illustrated embodiment. It differs from that based on the 8 Explained embodiment that the web-side magnetic field generating devices 1100 are accommodated in a longitudinal direction of the guide bar extending groove, as particularly clear in the Figure 10d ) and 10f ) recognizable. It can also be seen that the web-side magnetic field generating devices 1100 protrude slightly beyond the groove on their side facing away from the groove bottom. When the web-side magnetic field generating devices are made from an elastomer magnet, an additional buffer function can be achieved in this way. To ensure satisfactory emergency operation, the in 10 illustrated embodiment of the invention similar to that based on in 8 embodiment explained on the side facing away from the door leaf of the magnetic field generating devices 1010 and 1100 guide rollers 32 and 34 are provided. Such supplementary mechanical guide devices in the form of guide rollers, guide pins, guide bolts or the like can be provided in all embodiments of the invention.

Ferner hat es sich im Rahmen der Erfindung als besonders vorteilhaft erwiesen, wenn die Träger 1040 für die torblattseitigen Magnetfelderzeugungseinrichtungen 1010 zumindest teilweise aus einem ferromagnetischen Material gebildet sind, in dem die Feldlinien der auf einander gegenüberliegenden Seiten der stegseitigen Magnetfelderzeugungseinrichtung angeordneten Magnete zurückgeführt werden, um so ein besonders starkes Magnetfeld im Spalt zwischen den einander gegenüberliegenden torblattseitigen Permanentmagneten zur Verfügung zu stellen.Furthermore, it has proven to be particularly advantageous within the scope of the invention if the supports 1040 for the magnetic field generating devices 1010 on the door leaf side are formed at least partially from a ferromagnetic material, in which the field lines of the magnets arranged on opposite sides of the web-side magnetic field generating device are fed back, so as to to provide a particularly strong magnetic field in the gap between the opposing permanent magnets on the door leaf.

Wie besonders deutlich in Fig. 10e) erkennbar ist, sind die stegseitigen Magnetfelderzeugungseinrichtungen, die vorzugsweise in Form von sogenannten Elastomermagneten gebildet sind, auch in einem spiralförmig umlaufenden Abschnitt 120 des Führungsstegs 100 vorgesehen. So kann auch im Bereich des spiralförmigen Abschnitts eine berührungsfreie Führung der Torblattbewegung erreicht werden, wobei in diesem Bereich die ergänzenden mechanischen Führungseinrichtungen mit besonderem Vorteil eingesetzt werden.As is particularly evident in Figure 10e ) can be seen, the web-side magnetic field generating devices, which are preferably in the form of so-called elastomer magnets, are also provided in a spirally encircling section 120 of the guide web 100 . In this way, contact-free guidance of the door leaf movement can also be achieved in the area of the spiral-shaped section, with the additional mechanical guide devices being used with particular advantage in this area.

Die Erfindung ist nicht auf die anhand der Zeichnung dargestellte Ausführungsform beschränkt. Vielmehr ist auch an den Einsatz von erfindungsgemäßen Toren in Form von sogenannten Sektionaltoren gedacht, bei denen das Torblatt in der Öffnungsstellung über Kopf etwa in einer Horizontalebene angeordnet ist. Die Erfindung kann auch mit Vorteil bei sogenannten Folientoren eingesetzt werden, bei denen das Torblatt aus mit Hilfe von Verstärkungsprofilen verstärkten Kunststofffolien besteht. Die Führungsflächen des Führungsstegs können auch einen spitzen Winkel miteinander einschließen. Die Führungsrollen können auch ohne Zwischenschaltung eines Gelenkglieds unmittelbar an den Torblattgliedern befestigt sein, wenn die gelenkige Verbindung zwischen den Torblattgliedern mit Hilfe von gesonderten Gelenken erfolgt. Die bei einem erfindungsgemäßen Tor vorgesehenen Halter für die Führungsrollen können aus Stahlblech, aus Aluminiumdruckguss oder aus gefrästem Stahl hergestellt sein.The invention is not limited to the embodiment shown in the drawing. Rather, the use of doors according to the invention in the form of so-called sectional doors is also contemplated, in which the door leaf is arranged overhead in the open position approximately in a horizontal plane. The invention can also be used to advantage in so-called foil gates in which the gate leaf consists of plastic foils reinforced with the aid of reinforcing profiles. The guide surfaces of the guide web can also enclose an acute angle with one another. The guide rollers can also be attached directly to the door leaf members without the interposition of an articulated member if the articulated connection between the door leaf members is effected with the aid of separate joints. The holders provided for the guide rollers in a door according to the invention can be made of sheet steel, die-cast aluminum or milled steel.
