Definitions
- the invention relates to a door with a door leaf that can be moved along a path between a closed position, in which it is arranged approximately in a vertical plane, and an open position, in which it is arranged overhead, approximately in a horizontal plane, along a path that is predetermined by a guide rail arrangement of door leaf members arranged one behind the other in the direction of movement of the door leaf and hingedly connected to one another with respect to axes running perpendicular to the specified path, the guide rail arrangement having two guide rails arranged in the area of the side edges of the door leaf running parallel to the specified path, each of which has a first, approximately parallel to a lateral edge of the door leaf in the closed position approximately in the direction of gravity essentially in a straight line, a second, approximately parallel to a lateral edge of the door leaf in the open position and essentially straight approximately in the horizontal direction section and an arcuate section connecting the rectilinear sections to each other, in which in the area of the end of the second rectilinear section facing away from the ar
- Such gates are used for closing conventional garages but also for closing building openings with a height of 3.50 m or more, as they occur in industrial halls, warehouses, aircraft hangars or the like, where appropriate clearance heights are required.
- the individual, articulated door leaf members pass through an arcuate guide rail section in which they are deflected between a vertical orientation, which they assume in the closed position, and a generally horizontal orientation, which is assumed in the open position.
- This enables the door leaf to move without having to provide an excessive amount of space for large-area closing elements that swivel out.
- the opening movement is usually supported with the aid of a weight compensation arrangement which generally has a spring arrangement and with which the door leaf is urged into the open position.
- the spring arrangement is tensioned during the closing movement while absorbing the potential energy given off by the door leaf.
- the energy stored in the spring arrangement is then available to support the opening movement.
- the spring arrangement is usually coupled to the door leaf via a traction device.
- the traction means is attached on the one hand to the lower edge of the door leaf in the closed position and can be wound onto a winding device at its other end in the course of the opening movement.
- the door leaf In the open position, the door leaf is approximately in a horizontal plane, whereby the lower edge of the door leaf trailing during the opening movement can still be arranged in the area of the arcuate guide rail section and also drops in the open position with respect to the other door leaf members in the direction of the closed position.
- This facilitates the initiation of the closing movement, in which the force exerted by the counterbalance arrangement on the door leaf and pushing the door leaf towards the open position has to be overcome, because the weight of the door leaf is not completely absorbed by the second straight guide rail section, but rather already in the area of the arcuate guide rail section has a component running parallel to a tangent to this arcuate section, which component is available to accelerate the door leaf in the direction of the closed position.
- Such a pretensioning device can have a compression spring running approximately parallel to the second rectilinear section running around the spring axis, which is compressed when the opening position of the door leaf is reached and so tensioned in that the door leaf edge leading during the opening movement runs up against a contact area of the pretensioning device or the compression spring and compresses the compression spring against its preload force.
- the energy stored in this way in the compression spring is then available to provide a sufficient breakaway torque for the initiation of the closing movement against the force of the weight compensation device urging the door leaf into the open position.
- Goals according to the preamble of claims 1 and 11 are in the WO 02/055824 A1 specified.
- the invention is based on the object of providing a door that is easy to assemble and with which a breakaway force sufficient to initiate a closing movement can also be made available when a door leaf coupled to the door leaf and the door leaf in the open position urging weight compensation device is used.
- the fastening device for the prestressing device comprises a plug-in connection arrangement, in particular has a fastening tab that can be inserted into a corresponding receptacle.
- the invention is based on the knowledge that the observed assembly effort is primarily due to the fact that the fastening device of conventional goals has a screw connection with two, three or more screws, whereby it must be ensured during the assembly that the screwing points to each other with high accuracy be aligned. A considerable amount of time is required for this. Sometimes even two people are required to properly assemble the pretensioning device.
- a sufficiently secure fastening of the pretensioning device with respect to the second rectilinear section can also be achieved with the help of a simple plug-in connection in which an insert part is simply inserted into a suitable receptacle, whereby it can be ensured by appropriate shaping that the plug-in connection ensures that the position of the edge of the door leaf leading during the opening movement is in the correct position in the open position.
- the plug connection can be provided by a simple fastening strap which is inserted into a corresponding receptacle during assembly.
- the fastening device has a pretensioning device carrying the pretensioning device, which preferably has a helical circumferential compression spring, preferably a spring axis running approximately parallel to the second rectilinear section.
- the fastening device and the pretensioning device can be provided as a preassembled subassembly which is simple with respect to the second rectilinear section the guide rail can be mounted, the correct positioning of the pretensioning device can already be prepared by the pre-assembly of the pretensioning device and fastening device.
- the fastening tab can be arranged on the console, in particular have an expression of a console wall that is partially encircled by a slot penetrating the console wall, while in the assembled state the receptacle, which receives the tab protruding from the console wall, into which the fastening tab can be inserted in the course of assembly, is implemented in the second rectilinear section and / or a holder of the guide rail.
- the plug connection provided according to the invention is stabilized in the open position by the contact of the leading edge of the door leaf during the opening movement on a contact area of the pretensioning device under the action of the weight compensation device pushing the door leaf into the open position, in that the fastening tab is pushed against a limitation of the receptacle.
- the delimitation against which the fastening tab is urged in the open position of the door leaf can have an edge of the receptacle running approximately in the direction of gravity.
- the fastening device in addition to the plug-in connection, has a thread designed for receiving a fastening screw, which is preferably threaded through a threaded hole in a console wall, in particular the console wall having the fastening tab, is formed.
- the plug connection provided according to the invention can be secured with a corresponding screw connection. The plug connection enables correct positioning, which facilitates the screw connection and thus also simplifies the assembly of goals according to the invention overall in this embodiment.
- the threaded hole and the fastening tabs which can both be embodied in a console wall, can be spaced apart from one another in the longitudinal direction of the second rectilinear section. In this embodiment of the invention, after the plug connection has been produced, there is still enough space available for producing the screw connection.
- the fastening strap is attached to the bracket carrying the prestressing device.
- protruding fastening elements can be avoided in the area of the guide rail itself. This makes it easier to assemble goals according to the invention because it is not absolutely necessary to ensure that cantilevered components which impede the movement of the door leaf are correctly positioned on the guide rail arrangement.
- the plug connection is additionally secured with a screw connection
- the thread of the screw connection is arranged in the longitudinal direction of the second rectilinear section between the tab and the arcuate section.
- the screw required to produce the screw connection can penetrate a recess in the second rectilinear section and / or a holder of the guide rail, with a screw head in the assembled state on a boundary surface of the second rectilinear section facing away from the bracket the guide rail and / or the holder of the guide rail can rest.
- a particularly compact design of goals according to the invention can be achieved if the bracket carrying the pretensioning device is at least partially received in the second straight section of the guide rail, which is preferably designed as a J-rail or C-rail, in particular rests against the guide rail section with the bracket wall having the fastening tab .
- This particularly compact design is favored by the plug connection provided according to the invention, because such a plug connection can be easily produced without excessive installation space, while the screw connections otherwise provided in the prior art with two, three or more screwing points require such an installation space, so that assembly in the rail itself is hardly possible.
- the pretensioning device rests with an abutment area on the gate leaf edge advancing during the opening movement.
- the door leaf is made from so-called sandwich panels, in which the individual door leaf members comprise two metal shells, between which a layer of insulating material is attached, this can lead to deformation of the metal shells in the area of the leading edge during the opening movement.
- this deficiency can be eliminated in that the pretensioning device in the open position rests with its contact area on a roller holder for a guide roller received in the guide rail, which is attached to it in the area of the leading edge of the door leaf during an opening movement.
- a roller holder for a guide roller received in the guide rail, which is attached to it in the area of the leading edge of the door leaf during an opening movement.
- Such a roll holder is usually made so stable that there is no need to worry about deformation under the action of the pretensioning device.
- the particular embodiment of the invention described above in which the contact area rests on the roller holder, also enables a construction in which the distance between the spring axis and that on the second guide rail section adjacent console wall in a direction perpendicular to this console wall is less than 100 mm, preferably less than 75 mm, in particular about 50 mm.
- the leverage effect when the door leaf or the roller holder runs into the contact area of the pretensioning device, which determines the forces occurring in the area of the plug connection can be reduced.
- the plug connection can be further secured during continuous operation of doors according to the invention.
- This supplementary rail is only used to guide the door leaf element which is leading during the opening movement or trailing during the closing movement. With the supplementary rail, it is avoided that this door leaf member or the guide rollers attached to it have to pass through the arcuate guide rail section in the course of the closing movement. In this way, a complete room closure can be ensured even if there is only little installation space available above the opening to be closed.
- the bracket of the fastening device for the pretensioning device can be arranged in the second straight guide rail section and, in the open position, interact with the roller holder for the guide roller received in the supplementary rail.
- a prestressing arrangement according to the invention designed for the production of a gate according to the invention can have a prestressing device and a bracket for it, wherein a bracket wall is equipped with a fastening strap which can be implemented in the form of an expression that partially, in particular U-shaped, encircle a slot penetrating the bracket wall is.

- the energy stored in this way in the compression spring 60 is available to provide a breakaway torque sufficient to initiate the closing movement.
- the pretensioning device 60 has a helical compression spring 64 running around a spring axis running parallel to the second straight guide rail section. At its end facing the arcuate guide rail section (not shown), the pretensioning device 60 is equipped with a contact area 62 made of a flexible material such as an elastomer. As with the Fig.

Description
Die Erfindung betrifft ein Tor mit einem längs einer durch eine Führungsschienenanordnung vorgegebenen Bahn zwischen einer Schließstellung, in der es etwa in einer Vertikalebene angeordnet ist, und einer Öffnungsstellung, in der es über Kopf etwa in einer Horizontalebene angeordnet ist, bewegbaren Torblatt, das eine Mehrzahl von in Torblattbewegungsrichtung hintereinander angeordneten und bezüglich senkrecht zu der vorgegebenen Bahn verlaufenden Gelenkachsen gelenkig miteinander verbundenen Torblattgliedern aufweist, wobei die Führungsschienenanordnung zwei im Bereich der parallel zu der vorgegebenen Bahn verlaufenden seitlichen Ränder des Torblatts angeordnete Führungsschienen aufweist, von denen jede einen ersten, etwa parallel zu einem seitlichen Rand des Torblatts in der Schließstellung etwa in Schwererichtung im Wesentlichen geradlinig verlaufenden Abschnitt, einen zweiten, etwa parallel zu einem seitlichen Rand des Torblatts in der Öffnungsstellung im Wesentlichen geradlinig und etwa in horizontaler Richtung verlaufenden Abschnitt und einen die geradlinig verlaufenden Abschnitte miteinander verbindenden bogenförmigen Abschnitt aufweist, bei dem im Bereich des dem bogenförmigen Abschnitt abgewandten Endes des zweiten geradlinig verlaufenden Abschnitts eine das Torblatt in der Öffnungsstellung in Richtung auf die Schließstellung drängende und mit Hilfe einer Befestigungseinrichtung bezüglich des zweiten geradlinig verlaufenden Abschnitts festgelegte Vorspanneinrichtung angebracht ist.The invention relates to a door with a door leaf that can be moved along a path between a closed position, in which it is arranged approximately in a vertical plane, and an open position, in which it is arranged overhead, approximately in a horizontal plane, along a path that is predetermined by a guide rail arrangement of door leaf members arranged one behind the other in the direction of movement of the door leaf and hingedly connected to one another with respect to axes running perpendicular to the specified path, the guide rail arrangement having two guide rails arranged in the area of the side edges of the door leaf running parallel to the specified path, each of which has a first, approximately parallel to a lateral edge of the door leaf in the closed position approximately in the direction of gravity essentially in a straight line, a second, approximately parallel to a lateral edge of the door leaf in the open position and essentially straight approximately in the horizontal direction section and an arcuate section connecting the rectilinear sections to each other, in which in the area of the end of the second rectilinear section facing away from the arcuate section a door leaf in the open position in the direction of the closed position and with the help of a fastening device with respect to the second rectilinear portion fixed biasing means is attached.
Derartige Tore werden zum Verschließen herkömmlicher Garagen aber auch zum Verschließen von Gebäudeöffnungen mit einer Höhe von 3,50 m oder mehr eingesetzt, wie sie im Bereich von Industriehallen, Lagerhallen, Flugzeughangars oder dergleichen vorkommen, bei denen entsprechende Durchfahrtshöhen benötigt werden.Such gates are used for closing conventional garages but also for closing building openings with a height of 3.50 m or more, as they occur in industrial halls, warehouses, aircraft hangars or the like, where appropriate clearance heights are required.
Die einzelnen, gelenkig miteinander verbundenen Torblattglieder durchlaufen bei einer Öffnungs- oder Schließbewegung einen bogenförmigen Führungsschienenabschnitt, in dem sie zwischen einer vertikalen Ausrichtung, die sie in der Schließstellung einnehmen, und einer im Allgemeinen horizontalen Ausrichtung, die in der Öffnungsstellung eingenommen wird, umgelenkt werden. Das ermöglicht eine Torblattbewegung, ohne dafür übermäßig viel Raum für ausschwenkende, großflächige Schließelemente zur Verfügung stellen zu müssen. Bei entsprechenden Toren wird die Öffnungsbewegung üblicherweise mit Hilfe einer im Allgemeinen eine Federanordnung aufweisenden Gewichtsausgleichsanordnung unterstützt, mit der das Torblatt in die Öffnungsstellung gedrängt wird.During an opening or closing movement, the individual, articulated door leaf members pass through an arcuate guide rail section in which they are deflected between a vertical orientation, which they assume in the closed position, and a generally horizontal orientation, which is assumed in the open position. This enables the door leaf to move without having to provide an excessive amount of space for large-area closing elements that swivel out. In the case of corresponding doors, the opening movement is usually supported with the aid of a weight compensation arrangement which generally has a spring arrangement and with which the door leaf is urged into the open position.
Die Federanordnung wird bei der Schließbewegung unter Aufnahme der dabei vom Torblatt abgegebenen potentiellen Energie gespannt. Die in der Federanordnung gespeicherte Energie steht dann zur Unterstützung der Öffnungsbewegung zur Verfügung. Dazu ist die Federanordnung üblicherweise über ein Zugmittel an das Torblatt gekoppelt. Das Zugmittel ist einerseits an dem in Schließstellung unteren Rand des Torblatts befestigt und kann an seinem anderen Ende im Verlauf der Öffnungsbewegung auf einer Wickeleinrichtung aufgewickelt werden.The spring arrangement is tensioned during the closing movement while absorbing the potential energy given off by the door leaf. The energy stored in the spring arrangement is then available to support the opening movement. For this purpose, the spring arrangement is usually coupled to the door leaf via a traction device. The traction means is attached on the one hand to the lower edge of the door leaf in the closed position and can be wound onto a winding device at its other end in the course of the opening movement.
In der Öffnungsstellung befindet sich das Torblatt etwa in einer Horizontalebene, wobei der bei der Öffnungsbewegung nachlaufende untere Rand des Torblatts noch im Bereich des bogenförmigen Führungsschienenabschnitts angeordnet sein kann und auch in der Öffnungsstellung bezüglich der anderen Torblattglieder in Richtung auf die Schließstellung abfällt. Dadurch wird die Einleitung der Schließbewegung, bei der die von der Gewichtsausgleichsanordnung auf das Torblatt ausgeübte und das Torblatt in Richtung auf die Öffnungsstellung drängende Kraft überwunden werden muss, erleichtert, weil die Gewichtskraft des Torblatts nicht vollständig von dem zweiten geradlinig verlaufenden Führungsschienenabschnitt aufgenommen wird, sondern bereits im Bereich des bogenförmigen Führungsschienenabschnitts eine parallel zu einer Tangente an diesen bogenförmigen Abschnitt verlaufende Komponente aufweist, welche zur Beschleunigung des Torblatts in Richtung auf die Schließstellung zur Verfügung steht.In the open position, the door leaf is approximately in a horizontal plane, whereby the lower edge of the door leaf trailing during the opening movement can still be arranged in the area of the arcuate guide rail section and also drops in the open position with respect to the other door leaf members in the direction of the closed position. This facilitates the initiation of the closing movement, in which the force exerted by the counterbalance arrangement on the door leaf and pushing the door leaf towards the open position has to be overcome, because the weight of the door leaf is not completely absorbed by the second straight guide rail section, but rather already in the area of the arcuate guide rail section has a component running parallel to a tangent to this arcuate section, which component is available to accelerate the door leaf in the direction of the closed position.
Auch bei dieser Anordnung des Torblatts in der Öffnungsstellung, bei der das untere Torblattglied schon etwas nach unten hängt, reicht die zur Verfügung stehende Gewichtskraft in vielen Fällen nicht aus, um ein Losbrechmoment zur Einleitung einer Schließbewegung bereitzustellen, bei der das an die Gewichtsausgleichseinrichtung gekoppelte Zugmittel von der Wickeleinrichtung abgewickelt werden muss, um so überhaupt eine Schließbewegung zu ermöglichen. Aus diesem Grund sind herkömmliche Tore der eingangs beschriebenen Art üblicherweise mit einer im Bereich des dem bogenförmigen Abschnitt abgewandten Endes des zweiten geradlinig verlaufenden Abschnitts angebrachten Vorspanneinrichtung ausgestattet, mit der das Torblatt in der Öffnungsstellung in Richtung auf die Schließstellung gedrängt wird.Even with this arrangement of the door leaf in the open position, in which the lower door leaf member already hangs down a little, the available weight is in many cases not sufficient to provide a breakaway torque to initiate a closing movement, in which the traction means coupled to the weight compensation device must be unwound from the winding device in order to enable a closing movement at all. For this reason, conventional doors of the type described above are usually equipped with a pretensioning device attached in the region of the end of the second rectilinear section facing away from the arcuate section, with which the door leaf is urged in the open position towards the closed position.
Eine derartige Vorspanneinrichtung kann eine eine etwa parallel zum zweiten geradlinig verlaufenden Abschnitt verlaufende Federachse umlaufende Druckfeder aufweisen, die bei Erreichen der Öffnungsstellung des Torblatts zusammengedrückt und so gespannt wird, indem der bei der Öffnungsbewegung vorlaufende Torblattrand auf einen Anlagebereich der Vorspanneinrichtung bzw. der Druckfeder aufläuft und die Druckfeder gegen deren Vorspannkraft zusammendrückt. Die so in der Druckfeder gespeicherte Energie steht dann zur Bereitstellung eines ausreichenden Losbrechmoments für die Einleitung der Schließbewegung gegen die das Torblatt in die Öffnungsstellung drängende Kraft der Gewichtsausgleichseinrichtung zur Verfügung.Such a pretensioning device can have a compression spring running approximately parallel to the second rectilinear section running around the spring axis, which is compressed when the opening position of the door leaf is reached and so tensioned in that the door leaf edge leading during the opening movement runs up against a contact area of the pretensioning device or the compression spring and compresses the compression spring against its preload force. The energy stored in this way in the compression spring is then available to provide a sufficient breakaway torque for the initiation of the closing movement against the force of the weight compensation device urging the door leaf into the open position.
Tore nach dem Oberbegriff der Patentansprüche 1 und 11 sind in der
Es hat sich allerdings gezeigt, dass die Montage von mit einer entsprechenden Vorspanneinrichtung ausgestatteten Toren einen hohen Zeitaufwand mit sich bringt.It has been shown, however, that the assembly of doors equipped with a corresponding pretensioning device is very time-consuming.
Angesichts dieser Probleme im Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein einfach montierbares Tor zur Verfügung zu stellen, mit dem eine zur Einleitung einer Schließbewegung ausreichende Losbrechkraft auch dann zur Verfügung gestellt werden kann, wenn eine an das Torblatt gekoppelte und das Torblatt in die Öffnungsstellung drängende Gewichtsausgleichseinrichtung zum Einsatz kommt.In view of these problems in the prior art, the invention is based on the object of providing a door that is easy to assemble and with which a breakaway force sufficient to initiate a closing movement can also be made available when a door leaf coupled to the door leaf and the door leaf in the open position urging weight compensation device is used.
Erfindungsgemäß wird diese Aufgabe durch eine Weiterbildung der bekannten Tore gelöst, die im Wesentlichen dadurch gekennzeichnet ist, dass die Befestigungseinrichtung für die Vorspanneinrichtung eine Steckverbindungsanordnung umfasst, insbesondere eine in eine entsprechende Aufnahme einführbare Befestigungslasche aufweist.According to the invention, this object is achieved by a further development of the known goals, which is essentially characterized in that the fastening device for the prestressing device comprises a plug-in connection arrangement, in particular has a fastening tab that can be inserted into a corresponding receptacle.
Die Erfindung geht auf die Erkenntnis zurück, dass der beobachtete Montageaufwand in erster Linie darauf zurückzuführen ist, dass die Befestigungseinrichtung herkömmlicher Tore eine Verschraubung mit zwei, drei oder mehr Schrauben aufweist, wobei während der Montage sichergestellt werden muss, dass die Verschraubungspunkte mit hoher Genauigkeit zueinander ausgerichtet werden. Dazu wird ein beachtlicher Zeitaufwand benötigt. Mitunter werden sogar zwei Personen für die ordnungsgemäße Montage der Vorspanneinrichtung benötigt.The invention is based on the knowledge that the observed assembly effort is primarily due to the fact that the fastening device of conventional goals has a screw connection with two, three or more screws, whereby it must be ensured during the assembly that the screwing points to each other with high accuracy be aligned. A considerable amount of time is required for this. Sometimes even two people are required to properly assemble the pretensioning device.
Im Rahmen der Erfindung wurde erkannt, dass eine ausreichend sichere Befestigung der Vorspanneinrichtung bezüglich des zweiten geradlinig verlaufenden Abschnitts auch mit Hilfe einer einfachen Steckverbindung verwirklicht werden kann, bei der ein Einsteckteil einfach in eine geeignete Aufnahme eingesteckt wird, wobei durch entsprechende Formgebung sichergestellt werden kann, dass durch die Steckverbindung eine lagerichtige Positionierung bezüglich des bei der Öffnungsbewegung vorlaufenden Rands des Torblatts in der Öffnungsstellung erfolgt.In the context of the invention, it was recognized that a sufficiently secure fastening of the pretensioning device with respect to the second rectilinear section can also be achieved with the help of a simple plug-in connection in which an insert part is simply inserted into a suitable receptacle, whereby it can be ensured by appropriate shaping that the plug-in connection ensures that the position of the edge of the door leaf leading during the opening movement is in the correct position in the open position.
Bei einer bevorzugten Ausführungsform der Erfindung kann die Steckverbindung durch eine einfache Befestigungslasche bereitgestellt werden, die bei der Montage in eine entsprechende Aufnahme eingeführt wird.In a preferred embodiment of the invention, the plug connection can be provided by a simple fastening strap which is inserted into a corresponding receptacle during assembly.
Eine weitere Montageerleichterung ist erreichbar, wenn die Befestigungseinrichtung eine die vorzugsweise eine etwa parallel zum zweiten geradlinig verlaufenden Abschnitt verlaufende Federachse wendelförmig umlaufende Druckfeder aufweisende Vorspanneinrichtung tragende Konsole aufweist. Bei dieser Ausführungsform der Erfindung können Befestigungseinrichtung und Vorspanneinrichtung als vormontierte Baugruppe bereitgestellt werden, die einfach bezüglich des zweiten geradlinig verlaufenden Abschnitts der Führungsschiene montiert werden kann, wobei die lagerichtige Positionierung der Vorspanneinrichtung schon durch die Vormontage von Vorspanneinrichtung und Befestigungseinrichtung vorbereitet werden kann.A further simplification of assembly can be achieved if the fastening device has a pretensioning device carrying the pretensioning device, which preferably has a helical circumferential compression spring, preferably a spring axis running approximately parallel to the second rectilinear section. In this embodiment of the invention, the fastening device and the pretensioning device can be provided as a preassembled subassembly which is simple with respect to the second rectilinear section the guide rail can be mounted, the correct positioning of the pretensioning device can already be prepared by the pre-assembly of the pretensioning device and fastening device.
Bei der zuletzt beschriebenen Ausführungsform der Erfindung kann die Befestigungslasche an der Konsole angeordnet sein, insbesondere eine Ausdrückung einer Konsolenwand aufweisen, die von einem die Konsolenwand durchsetzenden Schlitz teilweise umlaufen ist, während die im montierten Zustand die von der Konsolenwand auskragende Lasche aufnehmende Aufnahme, in die die Befestigungslasche im Verlauf der Montage einführbar ist, in dem zweiten geradlinig verlaufenden Abschnitt und/oder einem Halter der Führungsschiene ausgeführt ist.In the last-described embodiment of the invention, the fastening tab can be arranged on the console, in particular have an expression of a console wall that is partially encircled by a slot penetrating the console wall, while in the assembled state the receptacle, which receives the tab protruding from the console wall, into which the fastening tab can be inserted in the course of assembly, is implemented in the second rectilinear section and / or a holder of the guide rail.
Die erfindungsgemäß vorgesehene Steckverbindung wird in der Öffnungsstellung durch die Anlage des bei der Öffnungsbewegung vorlaufenden Rands des Torblatts an einem Anlagebereich der Vorspanneinrichtung unter der Wirkung der das Torblatt in die Öffnungsstellung drängenden Gewichtsausgleichseinrichtung stabilisiert, indem die Befestigungslasche gegen eine Begrenzung der Aufnahme gedrängt wird. Dabei kann die Begrenzung, gegen die die Befestigungslasche in der Öffnungsstellung des Torblatts gedrängt wird, einen etwa in Schwererichtung verlaufenden Rand der Aufnahme aufweisen.The plug connection provided according to the invention is stabilized in the open position by the contact of the leading edge of the door leaf during the opening movement on a contact area of the pretensioning device under the action of the weight compensation device pushing the door leaf into the open position, in that the fastening tab is pushed against a limitation of the receptacle. The delimitation against which the fastening tab is urged in the open position of the door leaf can have an edge of the receptacle running approximately in the direction of gravity.
Wenngleich auch durch die vorstehend erläuterte Steckverbindung bereits eine lagerichtige Positionierung der Vorspanneinrichtung möglich ist, hat es sich im Rahmen der Erfindung als besonders zweckmäßig erwiesen, wenn die Befestigungseinrichtung zusätzlich zu der Steckverbindung ein zum Aufnehmen einer Befestigungsschraube ausgelegtes Gewinde aufweist, das vorzugsweise durch eine Gewindebohrung in einer Konsolenwand, insbesondere der die Befestigungslasche aufweisenden Konsolenwand, gebildet ist. Mit einer entsprechenden Schraubverbindung kann die erfindungsgemäß bereitgestellte Steckverbindung gesichert werden. Dabei ermöglicht die Steckverbindung eine lagerichtige Positionierung, welche die Schraubverbindung erleichtert und so auch bei dieser Ausführungsform insgesamt die Montage erfindungsgemäßer Tore vereinfacht.Even though the plug-in connection explained above enables the pretensioning device to be correctly positioned, it has proven to be particularly expedient within the scope of the invention if the fastening device, in addition to the plug-in connection, has a thread designed for receiving a fastening screw, which is preferably threaded through a threaded hole in a console wall, in particular the console wall having the fastening tab, is formed. The plug connection provided according to the invention can be secured with a corresponding screw connection. The plug connection enables correct positioning, which facilitates the screw connection and thus also simplifies the assembly of goals according to the invention overall in this embodiment.
Bei der zuletzt beschriebenen Ausführungsform der Erfindung können die Gewindebohrung und die Befestigungslaschen, welche beide in einer Konsolenwand ausgeführt sein können, in Längsrichtung des zweiten geradlinig verlaufenden Abschnitts voneinander beabstandet sein. Bei dieser Ausführungsform der Erfindung steht nach Herstellung der Steckverbindung noch genügend Raum für die Herstellung der Schraubverbindung zur Verfügung.In the last-described embodiment of the invention, the threaded hole and the fastening tabs, which can both be embodied in a console wall, can be spaced apart from one another in the longitudinal direction of the second rectilinear section. In this embodiment of the invention, after the plug connection has been produced, there is still enough space available for producing the screw connection.
Die vorstehend beschriebene Selbstarretierung der Befestigungseinrichtung unter Wirkung der von der Gewichtsausgleichseinrichtung auf das Torblatt ausgeübten Kraft kann besonders zuverlässig sichergestellt werden, wenn sich die Befestigungslasche ausgehend von der Konsolenwand in Richtung auf das dem bogenförmigen Abschnitt abgewandten Ende des zweiten geradlinig verlaufenen Abschnitts erstreckt und/oder eine im Bereich des zweiten Führungsschienenabschnitts oder eines Halters davon vorgesehene Befestigungslasche sich ausgehend von einem Verbindungsbereich in Richtung auf den bogenförmigen Führungsschienenabschnitt erstreckt.The above-described self-locking of the fastening device under the effect of the force exerted by the weight compensation device on the door leaf can be ensured particularly reliably if the fastening strap extends from the console wall in the direction of the end of the second straight section facing away from the arcuate section and / or a Fastening tab provided in the area of the second guide rail section or a holder thereof extends, starting from a connection area, in the direction of the arcuate guide rail section.
Wie vorstehend bereits erläutert, ist die Befestigungslasche bei einer bevorzugten Ausführungsform der Erfindung an der die Vorspanneinrichtung tragenden Konsole angebracht. Auf diese Weise können auskragende Befestigungselemente im Bereich der Führungsschiene selbst vermieden werden. Das erleichtert die Konfektionierung erfindungsgemäßer Tore, weil nicht zwingend darauf geachtet werden muss, ob die Torblattbewegung behindernde auskragende Bauelemente an der Führungsschienenanordnung lagerichtig positioniert sind.As already explained above, in a preferred embodiment of the invention, the fastening strap is attached to the bracket carrying the prestressing device. In this way, protruding fastening elements can be avoided in the area of the guide rail itself. This makes it easier to assemble goals according to the invention because it is not absolutely necessary to ensure that cantilevered components which impede the movement of the door leaf are correctly positioned on the guide rail arrangement.
Bei erfindungsgemäßen Toren, bei denen die Steckverbindung zusätzlich mit einer Schraubverbindung gesichert wird, hat es sich als zweckmäßig erwiesen, wenn das Gewinde der Schraubverbindung in Längsrichtung des zweiten geradlinig verlaufenden Abschnitts zwischen der Lasche und dem bogenförmigen Abschnitt angeordnet ist. Die zur Herstellung der Schraubverbindung benötigte Schraube kann eine Ausnehmung in dem zweiten geradlinig verlaufenden Abschnitt und/oder einem Halter der Führungsschiene durchsetzen, wobei ein Schraubenkopf im montierten Zustand an einer der Konsole abgewandten Begrenzungsfläche des zweiten geradlinig verlaufenden Abschnitts der Führungsschiene und/oder des Halters der Führungsschiene anliegen kann.In gates according to the invention, in which the plug connection is additionally secured with a screw connection, it has proven to be useful if the thread of the screw connection is arranged in the longitudinal direction of the second rectilinear section between the tab and the arcuate section. The screw required to produce the screw connection can penetrate a recess in the second rectilinear section and / or a holder of the guide rail, with a screw head in the assembled state on a boundary surface of the second rectilinear section facing away from the bracket the guide rail and / or the holder of the guide rail can rest.
Eine besonders kompakte Bauweise erfindungsgemäßer Tore lässt sich erreichen, wenn die die Vorspanneinrichtung tragende Konsole zumindest teilweise in dem vorzugsweise als J-Schiene oder C-Schiene ausgeführten zweiten geradlinig verlaufenden Abschnitt der Führungsschiene aufgenommen ist, insbesondere mit der die Befestigungslasche aufweisenden Konsolenwand an dem Führungsschienenabschnitt anliegt. Diese besonders kompakte Bauweise wird durch die erfindungsgemäß vorgesehene Steckverbindung begünstigt, weil eine solche Steckverbindung ohne übermäßigen Montageraum einfach hergestellt werden kann, während die im Stand der Technik sonst vorgesehenen Schraubverbindungen mit zwei, drei oder mehr Verschraubungspunkten einen solchen Montageraum benötigen, so dass eine Montage in der Schiene selbst kaum möglich ist.A particularly compact design of goals according to the invention can be achieved if the bracket carrying the pretensioning device is at least partially received in the second straight section of the guide rail, which is preferably designed as a J-rail or C-rail, in particular rests against the guide rail section with the bracket wall having the fastening tab . This particularly compact design is favored by the plug connection provided according to the invention, because such a plug connection can be easily produced without excessive installation space, while the screw connections otherwise provided in the prior art with two, three or more screwing points require such an installation space, so that assembly in the rail itself is hardly possible.
Bei herkömmlichen Toren liegt die Vorspanneinrichtung mit einem Anlagebereich an dem bei der Öffnungsbewegung vorlaufenden Torblattrand an. Wenn das Torblatt aus sogenannten Sandwichpaneelen hergestellt ist, bei denen die einzelnen Torblattglieder zwei Metallschalen umfassen, zwischen denen einen Isolierstoffschicht angebracht ist, kann das zu einer Verformung der Metallschalen im Bereich des bei der Öffnungsbewegung vorlaufenden Rands führen.In conventional gates, the pretensioning device rests with an abutment area on the gate leaf edge advancing during the opening movement. If the door leaf is made from so-called sandwich panels, in which the individual door leaf members comprise two metal shells, between which a layer of insulating material is attached, this can lead to deformation of the metal shells in the area of the leading edge during the opening movement.
Im Rahmen dieser Erfindung kann dieser Mangel dadurch beseitigt werden, dass die Vorspanneinrichtung in der Öffnungsstellung mit Ihrem Anlagebereich an einem im Bereich des bei einer Öffnungsbewegung vorlaufenden Rands des Torblatts daran angebrachten Rollenhalter für eine in der Führungsschiene aufgenommene Führungsrolle anliegt. Ein solcher Rollenhalter wird üblicherweise so stabil ausgeführt, dass eine Verformung unter der Einwirkung der Vorspanneinrichtung nicht zu besorgen ist.In the context of this invention, this deficiency can be eliminated in that the pretensioning device in the open position rests with its contact area on a roller holder for a guide roller received in the guide rail, which is attached to it in the area of the leading edge of the door leaf during an opening movement. Such a roll holder is usually made so stable that there is no need to worry about deformation under the action of the pretensioning device.
Die vorstehend beschriebene besondere Ausführungsform der Erfindung, bei der der Anlagebereich an dem Rollenhalter anliegt, ermöglicht auch eine Konstruktion, bei der der Abstand zwischen der Federachse und der an dem zweiten Führungsschienenabschnitt anliegenden Konsolenwand in einer senkrecht zu dieser Konsolenwand verlaufenden Richtung weniger als 100 mm, vorzugsweise weniger als 75 mm, insbesondere etwa 50 mm beträgt. So kann die Hebelwirkung bei Auflaufen des Torblatts bzw. des Rollenhalters auf den Anlagebereich der Vorspanneinrichtung, welche die im Bereich der Steckverbindung auftretenden Kräfte bestimmt, reduziert werden. Insgesamt kann auf diese Weise eine weitere Sicherung der Steckverbindung während des Dauerbetriebs erfindungsgemäßer Tore erreicht werden.The particular embodiment of the invention described above, in which the contact area rests on the roller holder, also enables a construction in which the distance between the spring axis and that on the second guide rail section adjacent console wall in a direction perpendicular to this console wall is less than 100 mm, preferably less than 75 mm, in particular about 50 mm. In this way, the leverage effect when the door leaf or the roller holder runs into the contact area of the pretensioning device, which determines the forces occurring in the area of the plug connection, can be reduced. Overall, in this way, the plug connection can be further secured during continuous operation of doors according to the invention.
Bekanntermaßen kann ein vollständiger Abschluss der mit dem Torblatt zu verschließenden Öffnung in der Schließstellung auch dann sichergestellt werden, wenn oberhalb der Öffnung nur eine geringe Raumhöhe zur Verfügung steht, indem die Führungsschienenanordnung mit einer mit der im Bereich des bei der Öffnungsbewegung vorlaufenden Rands angebrachten Führungsrolle zusammenwirkenden Ergänzungsschiene ausgestattet wird, die einen oberhalb des zweiten geradlinig verlaufenden Abschnitts etwa parallel dazu verlaufenden dritten geradlinig verlaufenden Abschnitt aufweist.As is known, complete closure of the opening to be closed with the door leaf can also be ensured in the closed position if only a small room height is available above the opening, in that the guide rail arrangement interacts with a guide roller attached to the edge leading during the opening movement Supplementary rail is equipped, which has a third rectilinear section running approximately parallel to it above the second rectilinear section.
Diese Ergänzungsschiene dient nur zur Führung des bei der Öffnungsbewegung vorlaufenden bzw. bei der Schließbewegung nachlaufenden Torblattglieds. Mit der Ergänzungsschiene wird vermieden, dass dieses Torblattglied bzw. die daran angebrachten Führungsrollen im Verlauf der Schließbewegung den bogenförmigen Führungsschienenabschnitt durchlaufen müssen. So kann ein vollständiger Raumabschluss auch dann sichergestellt werden, wenn oberhalb der zu verschließenden Öffnung nur wenig Bauraum zur Verfügung steht. Bei dieser Ausführungsform der Erfindung kann die Konsole der Befestigungseinrichtung für die Vorspanneinrichtung in dem zweiten geradlinig verlaufenden Führungsschienenabschnitt angeordnet sein und in der Öffnungsstellung mit dem Rollenhalter für die in der Ergänzungsschiene aufgenommene Führungsrolle zusammenwirken.This supplementary rail is only used to guide the door leaf element which is leading during the opening movement or trailing during the closing movement. With the supplementary rail, it is avoided that this door leaf member or the guide rollers attached to it have to pass through the arcuate guide rail section in the course of the closing movement. In this way, a complete room closure can be ensured even if there is only little installation space available above the opening to be closed. In this embodiment of the invention, the bracket of the fastening device for the pretensioning device can be arranged in the second straight guide rail section and, in the open position, interact with the roller holder for the guide roller received in the supplementary rail.
Wenn die im Bereich des bei der Öffnungsbewegung vorlaufenden Rands angebrachte Führungsrolle über einen bezüglich einer parallel zu den Gelenkachsen verlaufenden Schwenkachse verschwenkbaren, an dem bei der Öffnungsbewegung vorlaufenden Rand angebrachten Halter im Bereich dieses Rands angebracht ist, kann der Anlagebereich bei erfindungsgemäßen Toren im Bereich der Schwenkachse an dem Rollenhalter anliegen. Eine zur Herstellung eines erfindungsgemäßen Tors ausgelegte erfindungsgemäße Vorspannanordnung kann eine Vorspanneinrichtung und eine Konsole dafür aufweisen, wobei eine Konsolenwand mit einer Befestigungslasche ausgestattet ist, die in Form einer Ausdrückung verwirklicht sein kann, die von einem die Konsolenwand durchsetzenden Schlitz teilweise, insbesondere U-förmig umlaufen ist.When the guide roller attached in the area of the leading edge during the opening movement is attached to the holder attached to the leading edge during the opening movement in the area of this edge via a pivot axis that is parallel to the joint axes and is attached in the area of this edge, the contact area can in gates according to the invention in the area of the pivot axis rest on the roller holder. A prestressing arrangement according to the invention designed for the production of a gate according to the invention can have a prestressing device and a bracket for it, wherein a bracket wall is equipped with a fastening strap which can be implemented in the form of an expression that partially, in particular U-shaped, encircle a slot penetrating the bracket wall is.
