Abstract
Description
Die Erfindung betrifft eine Verriegelung für pneumatisch angetriebene Wellenspindeln von Schwenk- und Drehtüren, welche Wellenspindeln für die Schwenktüren hin und her gehend drehbar und durch Anheben in einer vorgegebenen Endstellung verriegelbar ist.The The invention relates to a lock for pneumatically driven Shaft spindles of swing and revolving doors, which shaft spindles for the swing doors going back and forth rotatable and by lifting in a given End position can be locked.
Pneumatische Schwenkantriebe werden vor allem für die Schwenktüren von Bussen verwendet.pneumatic Part-turn actuators are mainly used for the swing doors of Buses used.
Wenn die Tür geöffnet oder geschlossen ist, erfolgt die Verriegelung der Tür in der jeweiligen Einstellung durch Anheben in eine erhöhte Stellung. Sowohl das Schwenken als auch das Anheben geschieht dabei bei den meisten Türen pneumatisch. In der verriegelten Endstellung, beispielsweise bei geschlossener Tür, wird die Wellenspindel pneumatisch angehoben. Der Mechanismus ist derart ausgelegt, dass die Tür in der angehobenen Stellung gehalten werden muß, wenn sie in der Endstellung, insbesondere der geschlossenen Endstellung verbleiben soll. Der Luftdruck muß daher anliegen, solange die Tür in der gewünschten Endstellung verbleiben soll.If the door open is closed, the locking of the door in the respective setting by lifting in an elevated position. Both the panning as well as the lifting takes place pneumatically on most doors. In the locked end position, for example, when closed Door, will the shaft spindle pneumatically raised. The mechanism is like that designed that door must be kept in the raised position when in the final position, especially the closed end position should remain. Of the Air pressure must therefore lie, as long as the door in the desired End position should remain.
Wenn der Luftdruck ausfällt, weil er beispielsweise ein Leck im Luftdrucksystem aufgetreten ist oder ein zugehöriger Kompressor funktionsunfähig ist, wird die zuvor durch den Luftdruck hochgehaltene Spindel absinken und damit die Tür freigeben. Das kann aus verschiedenen Gründen nicht akzeptiert werden. Bei Bussen, die als öffentliches Verkehrsmittel verwendet werden, wäre die Sicherheit der Fahrgäste nicht mehr zu gewährleisten, wenn sich die Schwenktüren des Busses widerstandslos öffnen lassen würden.If the air pressure fails, because he has occurred, for example, a leak in the air pressure system or an associated one Compressor inoperative is, the previously held by the air pressure spindle will fall and with it the door release. This can not be accepted for various reasons. For buses that are public Means of transport, the safety of passengers would not be to ensure more when the swing doors of the bus open without resistance would let.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Verriegelung für Schwenktüren zu schaffen, die eine Verriegelung einer Tür ermöglicht, ohne ein kontinuierlich existierendes Luftdrucknetz zu benötigen.Of the The invention is therefore based on the object to provide a lock for swing doors, the one locking a door allows without to need a continuously existing air pressure network.
Zur Lösung dieser Aufgabe ist die erfindungsgemäße Verriegelung dadurch gekennzeichnet, dass im unteren Endbereich der Wellenspindel ein quer zur Wellenspindel verlaufender Exzenter vorgesehen ist, der in der ersten Winkelstellung außerhalb der Bahn der Wellenspindel liegt, in einer zweiten Winkelstellung dagegen in die Bahn der Wellenspindel eintritt.to solution this object the locking according to the invention is characterized that in the lower end of the shaft spindle a transverse to the shaft spindle extending eccentric is provided, in the first angular position outside the path of the shaft spindle is in a second angular position in contrast, enters the path of the shaft spindle.
Mit einem derartigen Exzenter ist es möglich, die Wellenspindel in der angehobenen Stellung mechanisch zu verriegeln, ohne dass dauerhaft Luftdruck benötigt wird. Das bedeutet, dass die Tür beispielsweise dauerhaft in der geschlossenen Stellung auch dann verbleibt, wenn der Luftdruck im Luftdrucknetz ausfällt. Auf diese Weise wird die Sicherheit beim Betrieb des zugehörigen Busses oder sonstigen Fahrzeugs erheblich erhöht. Ein unbeabsichtigtes Öffnen oder Schließen der Türen wird ausgeschlossen. Zugleich dient die erfindungsgemäße Verriegelung als Einbruchs-Schutz. Eine zusätzliche Verriegelung kann entfallen.With Such an eccentric, it is possible, the shaft spindle in mechanically lock the raised position without permanently Air pressure needed becomes. That means the door For example, then permanently in the closed position remains when the air pressure in the air pressure network fails. On this way, the security in the operation of the associated bus or other vehicle significantly increased. An accidental opening or Shut down the doors is excluded. At the same time the lock according to the invention is used as burglary protection. An additional lock can be omitted.

werden, wie er in der
Der
Dreh- oder Schwenkantrieb, der in der
Eine Wellenspindel mit zwei einander gegenüberliegenden, flachen Schraubengängen wird in Abstand von einem Zylinder umgeben, in dem ein Kolben verschiebbar angeordnet ist, der naturgemäß von der Wellenspindel durchlaufen wird. In dem Kolben sind auf gegenüberliegenden Seiten quer zur Längsachse der Spindel gelagerte, drehbare Rollen angeordnet, die sich auf den beiden flachen Gewindegängen abstützen. Damit sich der Kolben im Zylinder nicht verdrehen kann, wird er parallel zur Zylinderachse von zwei Führungsstangen durchlaufen.A Shaft spindle with two opposite, flat screw threads is Surrounded at a distance from a cylinder in which a piston displaceable is arranged by nature of the Is traversed shaft spindle. In the piston are on opposite Sides transverse to the longitudinal axis the spindle mounted, rotatable rollers arranged on the two flat threads support. So that the piston in the cylinder can not twist, he will go through parallel to the cylinder axis of two guide rods.
Der Kolben kann pneumatisch im Zylinder hin und her bzw. aufwärts und abwärts verfahren werden. Da der Kolben zum einen drehfest geführt ist und andererseits die Wellenspindel zwischen den beiden Rollen, die im Kolben gelagert sind und die mit den beiden gegenüberliegenden Gewindegängen zusammenwirken, zwangsgeführt ist, wird bei einer Verschiebung des Kolbens im Zylinder die Wellenspindel gedreht.Of the Piston can be pneumatically in the cylinder back and forth or upwards and down be moved. Since the piston is guided for a rotationally fixed and on the other hand, the shaft spindle between the two rollers, in the Pistons are stored and those with the two opposite Co-ordinating threads, forced out is, is at a displacement of the piston in the cylinder, the shaft spindle turned.
Die Wellenspindel endet am unteren Ende in einem zylindrischen Zapfen, der sich in einem Lager befindet und durch dieses bei der Drehung der Wellenspindel drehbar geführt ist. Der Zapfen ermöglicht im übrigen eine Höhenverschiebung der Wellenspindel bei Bewegung des Kolbens in die obere Endstellung.The Shaft spindle ends at the lower end in a cylindrical pin, which is in a warehouse and through this during rotation the shaft spindle rotatably guided is. The pin allows the rest of a height displacement the shaft spindle upon movement of the piston in the upper end position.
Während der Verriegelungsphase wird der Kolben und damit die Wellenspindel durch den Luftdruck in der Zylinderkammer unterhalb des Kolbens in der oberen Stellung gehalten.During the Locking phase, the piston and thus the shaft spindle through the air pressure in the cylinder chamber below the piston in the held in the upper position.
Wenn in dieser Stellung das Druckluftnetz, aus welchen Gründen auch immer, zusammenbricht, wird die Wellenspindel und damit die Tür absinken, und der Verriegelungseffekt entfällt.If in this position the compressed air network, for whatever reason, collapses, the shaft spindle and thus the door will sink, and the locking effect is eliminated.
Die Erfindung befaßt sich damit, die Verriegelung auf andere Art vorzunehmen.The Invention concerned to do the locking in a different way.
Vorzugsweise weist die Wellenspindel am unteren Ende eine zylindrischen Lagerzapfen auf, der in einem zylindrischen Gleitlager vertikal verschiebbar ist. Diese Art der Lagerung ermöglicht es, die Wellenspindel anzuheben.Preferably has the shaft spindle at the bottom of a cylindrical bearing pin which can be moved vertically in a cylindrical plain bearing is. This type of storage allows it to lift the shaft spindle.
Der Exzenter zur Verriegelung der Wellenspindel kann als quer zur Wellenspindel gerichteter Bolzen ausgebildet sein, der durch das untere zylindrische Gleitlager verläuft.Of the Eccentric for locking the shaft spindle can be considered transverse to the shaft spindle directed bolt to be formed by the lower cylindrical Sliding bearing runs.
Vorzugsweise schneidet ein Bolzen das untere Gleitlager in einer exzentrischen Linie. Der Bolzen kann eine Ausklinkung aufweisen, die den Innenquerschnitt des Gleitlagers in einer der Drehstellungen des Bolzens entsprechend dem Querschnitt des Lagerzapfens ergänzt, insbesondere zu einem Kreis ergänzt. Der Bolzen ist vorzugsweise aus dem Lager herausgeführt und wird außerhalb des Lagers durch einen Stellantrieb angetrieben, der den Bolzen in die beiden Winkelstellungen bringt.Preferably a bolt cuts the bottom sleeve bearing in an eccentric Line. The bolt may have a notch, which is the inner cross section of the sliding bearing in one of the rotational positions of the bolt accordingly the cross section of the journal added, in particular to a Circle complements. The bolt is preferably led out of the bearing and will be outside the bearing is driven by an actuator that drives the bolt brings in the two angular positions.
Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.in the The following are preferred embodiments the invention with reference to the accompanying drawings explained in more detail.
