Abstract

Disclosed is a door comprising a door leaf which is movable between a closed position and an open position along a track that is predefined by means of a guide rail system. Said door leaf is provided with a plurality of panels which are disposed one behind another along the predefined track and are pivotally interconnected so as to be swivable about swivel pins that extend perpendicular to the predefined track. At least one guiding element, such as a guide roller, which is preferably accommodated in a guide rail and cooperates with the guide rail system so as to guide the movement of the door leaf, is fixed to at least two panels, preferably each panel with the aid of a roller shaft that extends perpendicular to the predefined track. The inventive door further comprises a safety mechanism encompassing a safety element that can be displaced between a released position in which the same allows a movement of the door leaf and a blocked position in which the same counteracts a movement of the door leaf from the open position into the closed position, said safety element resting against a stationary contact surface when being displaced into the blocked position. The safety mechanism also encompasses a pressing element which is fixed to the door leaf and by means of which the safety element can be pressed in the direction of the contact surface in the blocked position. In order to improve said door, the safety element and/or the pressing element are positioned outside the guide rail.

Description

Die Erfindung betrifft ein Tor nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a gate according to the preamble of patent claim 1.

Bei Sektionaltoren der gerade beschriebenen Art ist das Torblatt in der Schließstellung im allgemeinen in einer Vertikalebene angeordnet, während es in der Öffnungsstellung über Kopf in einer Horizontalebene angeordnet ist. Zur Führung der Torblattbewegung sind üblicherweise an jedem seitlichen Rand des Torblattes Führungsschienen angebracht, welche einen ersten vertikal und sich parallel zum seitlichen Rand des Torblattes in der Schließstellung erstreckenden Abschnitt, einen zweiten sich in horizontaler Richtung etwa parallel zum seitlichen Rand des Torblattes in der Öffnungsstellung erstreckenden Abschnitt und einen bogenförmigen Verbindungsabschnitt aufweisen. Am Torblatt sind mit diesen Führungsschienen zusammenwirkende Führungselemente, insbesondere um parallel zu den Schwenkachsen verlaufende Rollenachsen drehbar gelagerte Führungsrollen angeordnet, welche in die Führungsschienen eingreifen, um so eine störungsfreie Torblattbewegung zu ermöglichen.In sectional doors of the type just described, the door leaf is arranged in the closed position generally in a vertical plane, while it is arranged in the open position above the head in a horizontal plane. To guide the Torblattbewegung guide rails are usually mounted on each lateral edge of the door leaf, which a first vertically and extending parallel to the lateral edge of the door leaf in the closed position extending portion, a second in the horizontal direction approximately parallel to the lateral edge of the door leaf in the open position Section and have an arcuate connecting portion. On the door leaf cooperating with these guide rails guide elements, in particular about parallel to the pivot axes extending roller axes rotatably mounted guide rollers are arranged, which engage in the guide rails so as to allow a smooth Torblattbewegung.

Zur Unterstützung der Öffnungsbewegung des Torblattes von der Schließstellung in die Öffnungsstellung sind üblicherweise Gewichtsausgleichssysteme vorgesehen, die in Form von Zugfederpaketen oder Torsionsfedern verwirklicht werden können. Diese Federn sind üblicherweise über ein andererseits am unteren Rand des Torblattes befestigtes Zugmittel an das Torblatt gekoppelt und werden im Verlauf der Schließbewegung von der Öffnungsstellung in die Schließstellung gespannt, so daß die darin gespeicherte Energie zur Unterstützung der Öffnungsbewegung bereitsteht. Gleichzeitig wird mit diesen Gewichtsausgleichseinrichtungen ein ungebremstes Herabfallen des Torblattes im Verlauf der Schließbewegung verhindert.To assist the opening movement of the door leaf from the closed position to the open position usually weight compensation systems are provided which can be realized in the form of Zugfederpaketen or torsion springs. These springs are usually coupled via a hand, on the other hand, attached to the lower edge of the door leaf traction means to the door leaf and are stretched in the course of the closing movement of the open position to the closed position, so that the energy stored therein is ready to support the opening movement. At the same time an unrestrained fall of the door leaf in the course of the closing movement is prevented with these weight balancing devices.

Zur Vermeidung von Beschädigungen des Torblattes und insbesondere zur Vermeidung von Verletzungen der das Tor benutzenden Personen, muß auch dann ein unkontrolliertes Herabfallen des Torblattes verhindert werden, wenn das Zugmittel und/oder die als Gewichtsausgleichseinrichtung eingesetzten Federn brechen. Aus diesem Grund sind herkömmliche Tore der eingangs beschriebenen Art üblicherweise mit Sicherungseinrichtungen ausgestattet, welche bei einem Bruch des Zugmittels und/oder der die Gewichtsausgleichseinrichtung bildenden Federn einer Torblattbewegung entgegenwirken.To avoid damage to the door leaf and in particular to avoid injury to the person using the gate, uncontrolled falling of the door leaf must be prevented even if the traction means and / or the springs used as a weight balancing device break. For this reason, conventional gates of the type described above are usually equipped with securing devices which counteract at a fraction of the traction means and / or the weight balancing device forming springs of a Torblattbewegung.

Ein Tor mit einer derartigen Sicherungseinrichtung ist beispielsweise in der US 1,936,269 angegeben. Das in dieser Schrift beschriebene Tor weist eine Sicherungseinrichtung mit einem in Form einer Sperrklinke verwirklichten Sicherungselement auf, welches bei Bruch des Zugmittels in eine in der Führungsschiene vorgesehene Ausnehmung eingreift und so ein unkontrolliertes Herabfallen des Torblattes verhindert. Allerdings führt die Bereitstellung von Ausnehmungen in der Führungsschiene zu einer Schwächung der Führungsschiene. Aus diesem Grund ist die Führungsschiene des in dieser Schrift beschriebenen Tores als besonders stabile Bauelementanordnung mit einer Abstützplatte und insgesamt vier an diese Abstützplatte angeschweißten Winkelprofilen ausgeführt.A gate with such a security device is for example in the US 1,936,269 specified. The gate described in this document has a safety device with a realized in the form of a pawl securing element which engages in breaking the traction means in a recess provided in the guide rail recess and thus prevents uncontrolled falling of the door leaf. However, the provision of recesses in the guide rail leads to a weakening of the guide rail. For this reason, the guide rail of the door described in this document is designed as a particularly stable component arrangement with a support plate and a total of four welded to this support plate angle profiles.

Bei einem in der DE 37 30 363 C1 beschriebenen Tor weist die Sicherungseinrichtung einen am Torblatt befestigten Fangschlitten auf, in dem eine von der Führungsschiene getrennte Stange umgreifende Klemmbacken verschiebbar aufgenommen sind. Diese Sicherungseinrichtung ist konstruktiv besonders aufwendig, weil sie nicht nur einen Fangschlitten mit darin aufgenommenen Klemmbacken, sondern auch eine eigene Stange als Führung für den Fangschlitten erfordert. Darüber hinaus hat es sich bei Einsatz von mit derartigen Sicherungseinrichtungen ausgestatteten Toren gezeigt, daß damit eine zuverlässige Abbremsung des Torblattes bei einem Bruch des Zugmittels und/oder der Gewichtsausgleichseinrichtung nicht erreichbar ist.At one in the DE 37 30 363 C1 described gate, the securing device has a catch sled mounted on the door leaf, in which a separate from the guide rail rod encompassing jaws are slidably received. This safety device is structurally particularly complex because it requires not only a catch slide with recorded therein jaws, but also a separate rod as a guide for the catch slide. Moreover, it has been found in the use of equipped with such security devices gates that thus a reliable deceleration of the door leaf at a fraction of the traction means and / or the weight compensation device is not achievable.

Dieselben Probleme hinsichtlich der Betriebssicherheit treten auch bei einem in der DE 38 14 275 C2 beschriebenen Tor auf, dessen Sicherungseinrichtung einen von einer Feder gegen die Außenfläche der Führungsschiene preßbaren Bremsschuh aufweist. Eine wesentliche Verbesserung der Betriebszuverlässigkeit wird auch nicht mit den in der DE 38 00 404 A1 beschriebenen Sicherungseinrichtungen erreicht, bei denen ein Sperrglied in der Führungsschiene aufgenommen ist und bei Bruch des Zugmittels und/oder bei Beschädigung der Gewichtsausgleichseinrichtung mit einer Zugfeder gegen eine innere Begrenzungsfläche der Führungsschiene gedrängt wird, wobei Sperrzähne des Sperrgliedes in Anlage an diese Begrenzungsfläche gelangen. Schließlich wird eine Erhöhung der Betriebssicherheit auch nicht bei Kipptoren der in der CH 261913 beschriebenen Art erreicht, bei denen ein Kabelschuh 10 bei Bruch des Zugmittels unter der Wirkung einer Vorspanneinrichtung zwischen dem Torblatt und einen Pfosten eingeklemmt werden soll.The same problems in terms of reliability occur even in a in the DE 38 14 275 C2 described gate, the securing means comprises a pressable by a spring against the outer surface of the guide rail brake shoe. A substantial improvement of the operational reliability is also not with in the DE 38 00 404 A1 achieved in which a locking member is received in the guide rail and is urged at breakage of the traction device and / or damaging the counterbalancing device with a tension spring against an inner boundary surface of the guide rail, wherein ratchet teeth of the locking member come into contact with this boundary surface. Finally, an increase in operational safety is not at tilters in the CH 261913 achieved in which a cable lug 10 is to be clamped at break of the traction means under the action of a biasing device between the door leaf and a post.

Zur Lösung der vorstehend beschriebenen Probleme wird in der WO 03/087506 die eingangs beschriebene Weiterbildung der bekannten Tore vorgeschlagen, wobei das Sicherungselement der in der genannten Schrift beschriebenen Tore innerhalb der Führungsschiene aufgenommen ist und bei Bruch des Zugmittels und/oder der die Gewichtsausgleichseinrichtungen bildenden Federn mit Hilfe der in den Führungsschienen aufgenommenen Führungsrollen gegen eine innere Begrenzungsfläche der Führungsschienen gepreßt wird. Bei dieser Lösung wird eine die gewünschte Sperrwirkung aufhebende Ausweichbewegung des Torblattes mit dem daran befestigten Sicherungselement bei in die Sperrstellung verstelltem Sicherungselement dadurch verhindert, daß das in der Führungsschiene aufgenommene Führungselement das Sicherungselement in Richtung auf eine innere Begrenzungsfläche der Führungsschiene drängt, um so zuverlässig die gewünschte Blockierungswirkung des Sicherungselementes zu erreichen.To solve the problems described above, in the WO 03/087506 proposed the development of the known goals described above, wherein the securing element the gates described in said document is received within the guide rail and is pressed at breakage of the traction means and / or the weight balancing means forming springs with the aid of recorded in the guide rails guide rollers against an inner boundary surface of the guide rails. In this solution, the desired locking effect reversing evasive movement of the door leaf with the attached securing element is prevented in verstellem in the locked position fuse element characterized in that the recorded in the guide rail guide element urging the fuse element towards an inner boundary surface of the guide rail to reliably the desired To achieve blocking effect of the fuse element.

Allerdings hat es sich gezeigt, daß die Montage von Sektionaltoren der in der WO 03/087506 A1 beschriebenen Art in vielen Fällen Probleme bereitet.However, it has been shown that the installation of sectional doors in the WO 03/087506 A1 described in many cases causes problems.

Ferner sind Tore nach dem Oberbegriff des Patentanspruchs 1 in der DE 29711166 U angegeben.Furthermore, gates are according to the preamble of claim 1 in the DE 29711166 U specified.

Angesichts dieser Probleme im Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Tor der eingangs beschriebenen Art bereitzustellen, dessen Torblatt zuverlässig gegen unkontrolliertes Abstürzen gesichert und dennoch einfach montierbar ist.In view of these problems in the prior art, the present invention seeks to provide a gate of the type described above, the door leaf is reliably secured against uncontrolled crashes and yet easy to install.

Diese Aufgabe wird durch die im kennseichnenden Teil des Patentanspruchs 1 angegebene Weiterbildung der bekannten Tore gelöst.

An einem zweiten Kopplungsbereich 58 des Hebels 54 ist ein keilförmiges Sicherungselement 70 angebracht, wobei das Sicherungselement 70 um eine parallel zur Schwenkachse 51 verlaufende Kippachse 71 verkippbar an dem Hebel 50 festgelegt ist. Zusätzlich umfaßt die Sicherungseinrichtung 50 ein als Anlagerolle 72 ausgeführtes Preßelement, wobei die Anlagerolle 72 bzgl. der Schwenkachse 51 verdrehbar an dem Hebel 54 gehalten ist. Die Sicherungseinrichtung mit dem Hebel 54, dem Sicherungselement 70 und der Anlagerolle 72 ist vollständig außerhalb der Führungsschiene 20 angeordnet.The generally designated 50 securing means is attached by means of a parallel to the bearing pin 42 extending support bolt 52 on the connecting leg 32 of the fastener 30. The safety device comprises a total of 54 designated and about a parallel to the roller axis 43 extending pivot axis 51 pivotally mounted on the support pin 52 lever. On a first coupling region 56 of the lever 54, a traction means 60, which is coupled on the other hand to a drive device and / or a weight compensation device, is attached. At a second coupling portion 58 of the lever 54, a wedge-shaped securing element 70 is attached, wherein the securing element 70 is tiltable about a parallel to the pivot axis 51 extending tilting axis 71 is fixed to the lever 50. In addition, the securing device 50 comprises a press-on element 72 designed as a contact roller 72, wherein the contact roller 72 with respect to the pivot axis 51 is rotatably held on the lever 54. The securing device with the lever 54, the securing element 70 and the contact roller 72 is arranged completely outside the guide rail 20.

Dem Hebel 54 ist eine den Tragbolzen 52 umlaufende Torsionsfeder 90 zugeordnet, welche einerseits an dem Hebel 90 angreift und sich andererseits an dem Torblatt abstützt. Mit der Torsionsfeder 90 wird der Hebel 54 insgesamt in die in Fig. 1 mit dem Pfeil P angedeutete Richtung gedrängt. Das bedeutet, daß das am Kopplungsbereich 58 des Hebels 54 um die Kippachse 71 verkippbar befestigte Sicherungselement 70 mit Hilfe der Torsionsfeder 90 in Richtung auf die äußere Begrenzungsfläche des rechtwinklig glatt abgebogenen Schenkels 24 der Führungsschiene 20 gedrängt wird. Andererseits wird der Hebel 54 mit Hilfe des an den Kopplungsbereich 56 gekoppelten Zugmittels 60 bei unbeschädigter Gewichtsausgleichseinrichtung bzw. Antriebseinrichtung in der in Fig. 1 dargestellten Lage gehalten. Wenn das Zugmittel 60 reißt und/oder die Gewichtsausgleichseinrichtung und/oder die Antriebseinrichtung beschädigt wird, so daß die über das Zugmittel 60 auf den Hebel 54 ausgeübte Kraft nachläßt, wird der Hebel 54 mit Hilfe der Torsionsfeder 90 in der durch den Pfeil P angedeuteten Richtung verdreht. Dann gelangt das keilförmige Sicherungselement 70 zwischen die äußere Begrenzungsfläche des glatt abgebogenen Schenkels 24 der Führungsschiene 20 und die Anlagerolle 72. Auf diese Weise wird eine Bewegung des Torblattes von der Öffnungsstellung in die Schließstellung blockiert. Dabei wird eine Ausweichbewegung des Torblattes in einer senkrecht zur Torblattebene verlaufenden Richtung durch die in der Führungsschiene 20 aufgenommene Führungsrolle 40 verhindert.The lever 54 is associated with a supporting bolt 52 surrounding the torsion spring 90, which on the one hand acts on the lever 90 and on the other hand is supported on the door leaf. With the torsion spring 90, the lever 54 in total in the in Fig. 1 urged with the arrow P direction indicated. This means that at the coupling region 58 of the lever 54 about the tilting axis 71 tiltably mounted securing element 70 is urged by means of the torsion spring 90 in the direction of the outer boundary surface of the right angle bent leg 24 of the guide rail 20. On the other hand, the lever 54 with the aid of coupled to the coupling region 56 traction means 60 with undamaged weight balancer or drive means in the in Fig. 1 shown position held. When the traction means 60 tears and / or the counterbalancing device and / or the drive device is damaged, so that the force exerted on the lever 54 via the traction means 60 decreases, the lever 54 by means of the torsion spring 90 in the direction indicated by the arrow P direction twisted. Then, the wedge-shaped securing element 70 passes between the outer boundary surface of the smooth bent leg 24 of the guide rail 20 and the contact roller 72. In this way, a movement of the door leaf is blocked from the open position to the closed position. It will prevents an evasive movement of the door leaf in a direction perpendicular to the door leaf direction by the recorded in the guide rail 20 guide roller 40.

Als zusätzliche Sicherung ist bei der in den Fig. 1 bis 3 dargestellten Ausführungsform der Erfindung ein sich koplanar zum Verbindungsschenkel 32 des Befestigungselementes 30 und einstückig damit ausgeführtes Abstützelement 38 vorgesehen, welches sich bei einer Bewegung des Paneels 10 in einer senkrecht zur Torblattebene verlaufenden Richtung P1 (vgl. Fig. 2) mit einer Abstützfläche an einer als Widerlager dienenden inneren und der Führungsschiene 20 zugewandten Begrenzungsfläche 86 des Zargenschenkels 84 abstützt. In der so erreichten Sperrstellung ist die Anlagerolle 72 zwischen dem Sicherungselement 70 und der Anlagefläche des Abstützelementes 38 angeordnet. Auf diese Weise entsteht eine Verklemmung zwischen Führungsschiene, Anlagerolle und Abstützung zur Zarge. Das Torblatt wird gefangen.As an additional backup is in the in the Fig. 1 to 3 illustrated embodiment, a coplanar to the connecting leg 32 of the fastener 30 and integrally designed therewith supporting member 38 is provided, which in a movement of the panel 10 in a plane perpendicular to the door leaf direction P1 (see. Fig. 2 ) is supported with a support surface on a serving as an abutment inner and the guide rail 20 facing boundary surface 86 of the Zargenschenkels 84. In the blocking position reached in this way, the abutment roller 72 is arranged between the securing element 70 and the contact surface of the supporting element 38. In this way creates a deadlock between the guide rail, bearing roller and support to the frame. The gate leaf is caught.

Die Blockierungswirkung des Sicherungselementes wird bei der in den Fig. 1 bis 3 dargestellten Ausführungsform der Erfindung dadurch begünstigt, daß die Keilflächen des Sicherungselementes einen spitzen Winkel von etwa 20° miteinander einschließen. Zur Unterstützung der Blockierungswirkung des Sicherungselementes 70 ist die an die äußere Begrenzungsfläche des Führungsschienenschenkels 24 angreifende Keilfläche aus einem harten, aufgerauhten Material gebildet.The blocking effect of the securing element is in the in the Fig. 1 to 3 illustrated embodiment of the invention favors that the wedge surfaces of the securing element form an acute angle of about 20 ° with each other. To support the blocking effect of the securing element 70, the wedge surface engaging the outer boundary surface of the guide rail limb 24 is formed of a hard, roughened material.

Bei der Beschreibung der in den Fig. 4 bis 6 dargestellten Ausführungsform der Erfindung werden für die den Bauelementen der anhand der Fig. 1 bis 3 erläuterten Ausführungsform entsprechende Bauelemente die gleichen Bezugszeichen verwendet. Die in den Fig. 4 bis 6 dargestellte Ausführungsform der Erfindung unterscheidet sich im wesentlichen dadurch von der anhand der Fig. 1 bis 3 erläuterten Ausführungsform, daß bei Bruch des Zugmittels und/oder Beschädigung der Gewichtsausgleichseinrichtung und/oder der Antriebseinrichtung unter der Wirkung der Torsionsfeder 90 der Hebel 54 in der durch den Pfeil P' dargestellten Richtung verdreht wird, so daß das Sicherungselement 70 zwischen die Anlagerolle 72 und die innere Begrenzungsfläche 86 des Zargenschenkels 84 gelangt und nicht die Führungsschiene 20 beaufschlagt. Bei einer Versetzung des Torblattes unter der Keilwirkung des Sicherungselementes 70 in der durch den Pfeil P1' (vgl. Fig. 5) angedeuteten Richtung gelangt ein an dem Befestigungselement 30 festgelegtes und sich etwa parallel zum Schenkel 24 der Führungsschiene 20 erstreckendes Abstützelement 38 in Anlage an den Führungsschienenschenkel 24. In dieser Klemmstellung ist die Anlagerolle 72 zwischen dem Abstützelement 38 und dem Sicherungselement 70 angeordnet. Auf diese Weise entsteht, ebenso wie bei der anhand der Fig. 1 bis 3 erläuterten Ausführungsform der Erfindung, eine Verklemmung wischen Zarge und Führungsschiene, so daß das Torblatt gefangen wird. Bei der anhand der Fig. 4 bis 6 dargestellten Ausführungsform der Erfindung können die Anlagerolle 72 und das Sicherungselement 70 in einer parallel zur Rollenachse 43 verlaufenden Richtung unmittelbar neben dem Paneel 10 angeordnet werden, so daß bei Verstellung des Sicherungselementes 70 in die Sperrstellung nur eine kleine Hebelwirkung auftritt. Dann wird die Sicherungseinrichtung 50 des in den Fig. 4 bis 6 dargestellten Tores insgesamt weniger belastet als die anhand der Fig. 1 bis 3 erläuterte Sicherungseinrichtung.In the description of the in the 4 to 6 illustrated embodiment of the invention are for the components of the basis of Fig. 1 to 3 explained embodiment, the same reference numerals used. The in the 4 to 6 illustrated embodiment of the invention differs essentially by the basis of the Fig. 1 to 3 explained embodiment that at breakage of the traction means and / or damage to the counterbalancing device and / or the drive means under the action of the torsion spring 90, the lever 54 is rotated in the direction shown by the arrow P ', so that the securing element 70 between the Anrollolle 72 and the inner boundary surface 86 of the Zargenschenkels 84 passes and not the guide rail 20 is applied. In an offset of the door leaf under the wedging action of the securing element 70 in the direction indicated by the arrow P1 '(see. Fig. 5 ) indicated direction reaches a fixed to the fastener 30 and approximately parallel to the leg 24 of the guide rail 20 extending support member 38 into contact with the guide rail leg 24. In this clamping position is the Anrollolle 72nd disposed between the support element 38 and the securing element 70. In this way arises, as well as with the basis of the Fig. 1 to 3 explained embodiment of the invention, a jam between the frame and guide rail, so that the door leaf is caught. When using the 4 to 6 illustrated embodiment of the invention, the abutment roller 72 and the securing element 70 can be arranged in a direction parallel to the roller axis 43 direction immediately adjacent to the panel 10, so that upon adjustment of the fuse element 70 in the blocking position only a small leverage occurs. Then, the securing device 50 of the in 4 to 6 shown gates total less loaded than the basis of the Fig. 1 to 3 explained safety device.

Die Erfindung ist nicht auf die anhand der Zeichnung erläuterten Ausführungsbeispiele beschränkt. Vielmehr kann das Führungselement unter Vermeidung einer Führungsrolle in Form eines einfachen Führungsstiftes ausgebildet sein. Ferner kann vom Einsatz eines gesonderten Abstützelementes abgesehen werden, wenn die Abmessungen des Führungselementes derart auf die Abmessungen der Führungsschiene und des keilförmigen Sicherungselementes 70 abgestimmt sind, daß einer Ausweichbewegung des Torblattes in einer senkrecht zur Torblattebene verlaufenden Richtung bei Auflaufen der Anlagerolle auf das keilförmige Sicherungselement durch Anlage des Führungselementes an den inneren Begrenzungsflächen der Führungsschiene entgegengewirkt werden kann.The invention is not limited to the embodiments explained with reference to the drawing. Rather, the guide member may be formed while avoiding a leadership in the form of a simple guide pin. Furthermore, it can be dispensed with the use of a separate support element, if the dimensions of the guide element are matched to the dimensions of the guide rail and the wedge-shaped securing element 70, that an evasive movement of the door leaf in a plane perpendicular to the door leaf direction when running the Anrollolle on the wedge-shaped fuse element Installation of the guide element can be counteracted on the inner boundary surfaces of the guide rail.
