Abstract

The automatic opening mechanism possesses, for closing the door, a driving cylinder (8) which actuates an upper latch (5) and a lower bolt (7) via linkages (4, 6). So that this door lock can also be opened by remote control, there is a release cylinder (10) which is located on the door jamb (2) and the piston (11) of which acts on a tappet (13) connected to the linkage (4, 6) for unlocking the door. The release cylinder (10) works at the same time as a control slide for supplying pressure medium to the driving cylinder (8), in order to prevent the driving cylinder (8) from being actuated before the release of the opening mechanism. <IMAGE>

Description

Die Erfindung betrifft einen automatischen öffnungsmechanismus für Dreh- oder Falttüren, insbesondere von Fahrzeugen.The invention relates to an automatic opening mechanism for revolving or folding doors, in particular vehicles.

Bei Drehfalttüren von Eisenbahnwaggons älterer Bauart, welche von Hand geöffnet und geschlossen wurden, wurden zur Entlastung der Schaffner druckluftbeaufschlagte Schließzylinder eingebaut, welche ein automatisches Schließen aller Türen vom Fahrstand aus ermöglichten. Die Schließzylinder fielen dabei in ein federbelastetes Schloß ein, um die Verriegelung zu bewirken. Nur durch Betätigen der Handgriffe von Hand konnten diese Türen wieder geöffnet werden, was wegen der vielen Führungen und Gelenke noch erschwert wurde.In the case of revolving folding doors of older type railway wagons, which were opened and closed by hand, compressed air-actuated locking cylinders were installed to relieve the conductors, which enabled all doors to be closed automatically from the operator's position. The lock cylinders fell into a spring-loaded lock to effect the locking. These doors could only be opened again by operating the handles by hand, which was made even more difficult due to the many guides and joints.

Der Erfindung liegt daher die Aufgabe zugrunde, die Türen so umzubauen, daß ein automatisches ferngesteuertes öffnen der Türen möglich ist, ohne dazu an dem bestehenden Schloßmechanismus viel ändern zu müssen.The invention is therefore based on the object to convert the doors so that an automatic remote controlled opening the doors is possible without having to change much on the existing lock mechanism.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß am Türstock ein pneumatischer oder hydraulischer Entriegelungsantrieb vorgesehen ist, der gleichzeitig auch als Steuerschieber für den Öffnungszylinder dient.According to the invention, this object is achieved in that a pneumatic or hydraulic unlocking drive is provided on the door frame, which at the same time also serves as a control slide for the opening cylinder.

Weitere Merkmale der Erfindung sind in den Unteransprüchen angegeben.Further features of the invention are specified in the subclaims.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles, das auch in der Zeichnung dargestellt ist, näher beschrieben. Es zeigen:

  • Fig. 1 eine Ansicht der gesamten Tür und
  • Fig. 2 einen Querschnitt nach der Linie I-I der Fig. 1.
The invention is described below with reference to an embodiment which is also shown in the drawing. Show it:
  • Fig. 1 is a view of the entire door and
  • 2 shows a cross section along the line II of FIG. 1st

Wie insbesondere Fig. 1 zeigt, ist eine aus zwei gelenkig miteinander verbundenen Türblättern 1 bestehende Drehfalttür in einem Türstock 2 gelagert und wird über einen oberhalb der Tür im Türstock angebrachten pneumatischen Antriebszylinder 8 betätigt, der mit seinem Kolben an einen Führungswagen 9 des Türblattes 1 angreift und ursprünglich nur zum Schließen diente, wobei eine an der oberen Türkante angebrachte Schließfalle 5 und ein an der unteren Türkante angebrachter Riegel 7 unter Federbelastung ein Verriegeln der geschlossenen Tür bewirkten. Zur Öffnung diente ein Schloß 3 mit nicht gezeigten Betätigungshandgriffen, das über Gestänge 4, 6 mit der Schließfalle 5 und dem Riegel 7 verbunden ist. Um nun diese Tür auch auf automatischen öffnungsantrieb umzubauen, war es nicht nur notwendig, den Antriebszylinder 8 durch einen doppelt wirkenden Schließ-und öffnungszylinder zu ersetzen, sondern es mußte auch eine Konstruktion gefunden werden, die eine vorherige Entriegelung der Schließfalle 5 und des Riegels 7 bewirkte. Dies wird erfindungsgemäß dadurch erreicht, daß an der oberen Türkante am Türstock 2 ein Entriegelungsantrieb im Form eines druckluftbeaufschlagten Entriegelungszylinders 10 (Fig. 2) vorgesehen ist, dessen durch eine Feder 19 belasteter Kolben 11 mit seiner Kolbenstange 12 auf einen gegenüber im Türblatt angeordneten Stößel 13 wirkt, der über einen Hebel 14 mit dem vom Türschloß 3 zur Schließfalle 5 führenden Gestänge 4 gekuppelt ist und daher bei Betätigung durch den Kolben 11 die Schließfalle 5 entriegelt.Um auch den unteren Riegel 7 zu betätigen, ist das Gestänge 4 unter Umgehung des Schlosses 3 über ein weiteres Gestänge 16 auch mit dem unteren Riegel 7 verbunden. Um eine Gefährdung von Reisenden, die den Betätigungshandgriff bereits in der Hand halten, durch die Automatik zu vermeiden, ist der Handgriff vom Gestänge 4 durch eine nur in einer Richtung auf Druck wirkende Kupplung 15 mechanisch getrennt. Eine ähnliche Trennung erfolgt durch Langlochschlitze in den Gestängen 6 und 16 auch beim unteren Riegel 7. Es ist damit gewährleistet, daß die Verriegelung sowohl durch die Automatik als auch durch den Betätigungshandgriff gelöst werden kann, wobei bei automatischer Entriegelung der am Schloß 3 angeordnete Betätigungshandgriff nicht bewegt wird, da die Kupplung 15 nur in einer Richtung, nämlich nach aufwärts, eine Bewegung überträgt. Um zu gewährleisten, daß vor der Entriegelung der Antriebszylinder 8 nicht betätigt und damit ein Klemmen in den Riegeln verursacht wird, ist der Entriegelungszylinder 10 gleichzeitig als Steuerschieber für die Durckluftzufuhr und damit für die des Antriebszylinders 8 ausgebildet. Der Entriegelungszylinder 10 weist dazu im unteren Teil einen Austrittsschlitz (nicht sichtbar) auf, der über eine Leitung 17 mit dem Antriebszylinder 8 verbunden ist. Tritt nun die für das öffnen bestimmte Druckluft durch eine Leitung 18 oben in den Entriegelungszylinder 10 ein, so wird der Kolben 11 nach unten gedrückt, dabei über die Kolbenstange 12 der Stößel 13 betätigt und die Tür oben und unten entriegelt. Ist diese Entriegelung erfolgt, so hat der Kolben 11 auch den Austrittsschlitz bzw. die Leitung 17 erreicht und gibt dem Druckmedium damit den weiteren Weg zum Antriebszylinder 8 frei, wodurch die Tür nun geöffnet werden kann. Damit ist gewährleistet, daß beim Klemmen von Riegeln oder Gestängen und einer damit einhergehenden Blockierung des Kolbens 11 ein öffnen der Tür durch den Antriebszylinder 8 gar nicht eingeleitet und damit eine Beschädigung von mechanischen Teilen der Aufhängung und Verriegelung vermieden wird, was bei gleicher Betätigung der Zylinder 10 und 8 sicher der Fall wäre.As shown in FIG. 1 in particular, a rotary folding door consisting of two hingedly connected door leaves 1 is mounted in a door frame 2 and is actuated via a pneumatic drive cylinder 8 mounted above the door in the door frame, which engages with its piston on a guide carriage 9 of the door leaf 1 and originally only used for closing, a locking latch 5 attached to the upper door edge and a bolt 7 attached to the lower door edge causing the closed door to lock under spring loading. For the opening, a lock 3 with actuation handles, not shown, was used, which is connected via rods 4, 6 to the latch 5 and the bolt 7. In order to convert this door also to an automatic opening drive, it was not only necessary to replace the drive cylinder 8 by a double-acting locking and opening cylinder, but also a design had to be found which unlocked the latch 5 and the bolt 7 beforehand caused. This is achieved according to the invention in that an unlocking drive in the form of a compressed air-actuated unlocking cylinder 10 (FIG. 2) is provided on the upper door edge on the door frame 2, the piston 11 loaded by a spring 19 with its piston rod 12 on a plunger 13 arranged opposite in the door leaf acts, which is coupled via a lever 14 with the linkage 4 leading from the door lock 3 to the locking latch 5 and therefore unlocks the locking latch 5 when actuated by the piston 11. In order to also operate the lower bolt 7, the linkage 4 is bypassing the lock 3 also connected to the lower bolt 7 via a further linkage 16. In order to avoid a hazard to travelers who are already holding the actuating handle in the hand by the automatic system, the handle is mechanically separated from the linkage 4 by a coupling 15 acting only in one direction. A similar separation takes place through slot slots in the linkages 6 and 16 also in the lower bolt 7. It is thus ensured that the locking can be released both by the automatic and by the actuating handle, the actuating handle arranged on the lock 3 not being released upon automatic unlocking is moved because the clutch 15 transmits movement only in one direction, namely upwards. In order to ensure that the drive cylinder 8 is not actuated before unlocking and thus causes jamming in the bolts, the unlocking cylinder 10 is simultaneously designed as a control slide for the compressed air supply and thus for that of the drive cylinder 8. To this end, the unlocking cylinder 10 has an outlet slot (not visible) in the lower part, which is connected to the drive cylinder 8 via a line 17. If the compressed air intended for opening now enters the unlocking cylinder 10 through a line 18 at the top, the piston 11 is pressed down, thereby via the Piston rod 12 actuated the plunger 13 and unlocked the door at the top and bottom. Once this unlocking has taken place, the piston 11 has also reached the outlet slot or the line 17 and thus releases the pressure medium to travel further to the drive cylinder 8, so that the door can now be opened. This ensures that when locking bolts or rods and a concomitant blocking of the piston 11 an opening of the door by the drive cylinder 8 is not initiated and thus damage to mechanical parts of the suspension and locking is avoided, which with the same actuation of the cylinder 10 and 8 would certainly be the case.

Die Erfindung ist auf das dargestellte Ausführungsbeispiel nicht beschränkt, da anstelle einer Pneumatik auch eine Hydraulik verwendet werden kann und sich die entsprechenden-Antriebe auch seitlich am Türstock befinden können.The invention is not limited to the exemplary embodiment shown, since instead of pneumatics, hydraulics can also be used and the corresponding drives can also be located on the side of the door frame.
