Abstract

Eine Türverriegelung in einem Fahrzeug zur Personenbeförderung, insbesondere für eine Schwing- oder Schwenktür eines Omnibus, umfaßt ein Sicherheitsschloß mit einem Schließzylinder (1), der erfindungsgemäß mit einem elektrischen Schalter (6) wirkverbunden ist, der funktional einem durch den Fahrzeugführer bedienbaren Innentaster zum Öffnen und Schließen der Tür durch den Tür-Antrieb (12) parallelgeschaltet ist und nur bei Schlüsselbetätigung des Schließzylinders (1) im Entriegelungssinn zur Erzeugung eines Schaltsignals betätigt wird. <IMAGE>A door lock in a vehicle for the transportation of people, in particular for a swinging or swinging door of a bus, comprises a security lock with a lock cylinder (1) which, according to the invention, is operatively connected to an electrical switch (6) which is functionally operable to open an internal button operated by the vehicle driver and closing the door by the door drive (12) is connected in parallel and is actuated only when the key of the locking cylinder (1) is actuated in the unlocking direction to generate a switching signal. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Türverriegelung in einem Fahrzeug zur Personenbeförderung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1. Eine Türverriegelung mit diesen Merkmalen ist bekannt (DE 27 43 598 A1). Das Eindringen Unbefugter wird dadurch verhindert, daß die Tür von außen mit einem üblichen Sicherheitsschloß nicht näher beschriebener Bauart, das keinen Einfluß auf den Türantrieb hat, abgeschlossen wird.The invention relates to a door lock in a vehicle for the transportation of people with the features of the preamble of claim 1. A door lock with these features is known (DE 27 43 598 A1). The intrusion of unauthorized persons is prevented in that the door is locked from the outside with a conventional security lock of a type not described in detail, which has no influence on the door drive.

An Omnibussen ist normalerweise zum öffnen und Schließen der durch pneumatische Hubkolbenantriebe verschwenkbaren Schwing- oder Schwenktüren von außen ein Taster unter einer abschließbaren Klappe der Außenhaut des Fahrzeugs vorgesehen, der funktional parallel zum am Fahrerplatz angeordneten Fahrertaster geschaltet ist. Dessen Handhabung ist allerdings wegen der separaten Klappenschließung abseits der Tür relativ umständlich.On buses and coaches there is normally a button under the lockable flap of the vehicle's outer skin for opening and closing the swinging or swinging doors that can be pivoted by pneumatic reciprocating drives, which is connected functionally parallel to the driver button located in the driver's position. However, its handling is relatively cumbersome due to the separate flap closure off the door.

Die Erfindung hat die Aufgabe, eine gattungsgemäße Türverriegelung komfortabel bedienbar zu machen.The invention has the task of making a generic door lock easy to use.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Patentanspruchs 1 erfindungsgemäß gelöst.This object is achieved according to the invention with the characterizing features of patent claim 1.

Der Fahrer des Fahrzeugs kann nun zwei Maßnahmen, Türentriegelung und -öffnen, mit einem Handgriff erledigen. Denn der mit dem Schließzylinder wirkverbundene Schalter kann dazu benutzt werden, analog zu dem üblichen Fahrertaster, der zum Türöffnen durch den Fahrer von innen vorgesehen ist, bzw. funktional parallel zu diesem gleichzeitig mit oder geringfügig verzögert gegenüber der entriegelnden Schlüsselbetätigung des Schließzylinders den durch Fremdkraft (mit Luftdruck oder elektrisch) unterstützten öffnungsvorgang der zugeordneten Tür einzuleiten.The driver of the vehicle can now perform two measures, unlocking and opening the door, with one hand. This is because the switch, which is operatively connected to the locking cylinder, can be used for this, analogous to the usual driver button, that for opening the door is provided by the driver from the inside, or functionally parallel to this, at the same time with or slightly delayed compared to the unlocking key actuation of the locking cylinder to initiate the opening process of the associated door supported by external force (with air pressure or electrically).

An sich ist es bekannt, einem Schließzylinder einen oder mehrere elektrische Schalter zuzuordnen (DE 31 20 222 A1, DE 40 08 834 C1), um bei Schlüsselbetätigung des Schließzylinders Schaltsignale z. B. zur Steuerung einer Zentralverriegelungs- und/oder Diebstahlsicherungsanlage zu erzeugen. Aus diesen Anordnungen ist aber kein Hinweis auf die hier beschriebene komfortable Steuerung eines Türantriebs in einem Nutzfahrzeug entnehmbar.It is known per se to assign one or more electrical switches to a locking cylinder (DE 31 20 222 A1, DE 40 08 834 C1) in order to switch signals when the key cylinder is actuated. B. to control a central locking and / or anti-theft system. However, no reference to the convenient control of a door drive in a commercial vehicle described here can be derived from these arrangements.

Die kennzeichnenden Merkmale der Unteransprüche geben vorteilhafte Weiterbildungen der erfindungsgemäßen Türverriegelung an.The characteristic features of the subclaims indicate advantageous developments of the door lock according to the invention.

Der elektrische Schalter wird nur in einer Drehrichtung des Schließzylinders betätigt, nämlich in der Entriegelungs-Drehrichtung, während die entgegengesetzte Drehrichtung der mechanischen Verriegelung des Türschlosses bei geschlossener Tür dient.
Bei wiederholter Erzeugung des Schaltsignals des Schalters, der vorzugsweise als einpoliger Mikroschalter ausgeführt ist, wird jeweils die Arbeitsrichtung des gesteuerten Türantriebs gegenüber dem zuletzt abgelaufenen oder noch laufenden Betriebszyklus umgekehrt, d. h. nach dem Schaltsignal zum öffnen wird das nächste Schaltsignal zum Schließen der Tür führen und umgekehrt. Zwischen der Erzeugung des Schaltsignals, bei der der Schlüssel notwendigerweise im Schließzylinder steckt, und der Aktivierung des Türantriebs kann bei Bedarf eine gewisse Verzögerungszeitspanne eingehalten werden, die z. B. das Abziehen des Schlüssels vor dem Einsetzen der Türbewegung ermöglicht.The electrical switch is actuated only in one direction of rotation of the locking cylinder, namely in the unlocking direction of rotation, while the opposite direction of rotation serves to mechanically lock the door lock when the door is closed.
With repeated generation of the switch signal of the switch, which is preferably designed as a single-pole microswitch, the working direction of the controlled door drive is reversed compared to the last expired or still running operating cycle, i.e. after the switch signal to open, the next switch signal will result in the door being closed and vice versa . Between the generation of the switching signal, in which the key is necessarily in the lock cylinder, and the activation of the door drive, a certain delay can be observed if necessary, which, for. B. allows removal of the key before inserting the door movement.

In an sich bekannter Weise kann das Schaltsignal des elektrischen Schalters auch einer Zentralverriegelungsanlage zu deren Aktivierung im Entriegelungssinn zugeführt werden; auf diese hat eine Signalwiederholung bei geöffneter Tür - was zu deren Schließen notwendig ist - keinen Einfluß, weil regelmäßig bei geöffneter Tür bereits der entriegelte Zustand vorliegt. Für die zentrale Verriegelung wird dem Schließzylinder dann zweckmäßig ein zweiter Steuerschalter zugeordnet, der bei Drehen im Verriegelungssinn geschaltet wird und dann der Zentralverriegelungsanlage ein Schaltsignal zu deren Aktivierung im Verriegelungssinn zuführt.In a manner known per se, the switching signal of the electrical switch can also be fed to a central locking system for activating it in the unlocking direction; Repeating the signal when the door is open - which is necessary to close it - has no effect because the unlocked state is already regularly present when the door is open. For the central locking, a second control switch is then expediently assigned to the locking cylinder, which is switched when turning in the locking direction and then supplies the central locking system with a switching signal for its activation in the locking direction.

Weitere Einzelheiten und Vorteile gehen aus der Zeichnung eines Ausführungsbeispiels und deren sich hier anschließender eingehender Beschreibung hervor.Further details and advantages emerge from the drawing of an exemplary embodiment and the following detailed description thereof.

Ein Schließzylinder 1 ist in Figur 1 mit einem in einer neutralen Schlüsselabzugstellung eingesteckten Schlüssel 2 gezeigt. Mit einer Drehstange 3 am rückwärtigen Ende des Schließzylinders 1 ist eine drehbar in einem Türblech gelagerte Nuß 4 gekuppelt, über die in bekannter Weise über hier nicht sichtbare Hebel ein Türschloß mechanisch verriegelt werden kann. Vorzugsweise kann z. B. ein Türziehgriff von dem Schloß bzw. von der Aushebemechanik für eine Schloßfallen-Sperrklinke entkuppelt werden, wenn die Nuß 4 in die Verriegelungsstellung gedreht wurde. Für das Zurückdrehen des Schlüssels 2 in die Schlüsselabzugstellung ist üblicherweise ein Freilauf zwischen Nuß 4 und Schließzylinder 1 vorgesehen ("Schlüsselrückdrehspiel"). Der Schließzylinder 1 kann mit einer Drehfeder in die Schlüsselabzugstellung federnd rückgeführt werden.
Die Nuß 4 trägt an ihrem äußeren oberen Umfang einen Nocken 5.A lock cylinder 1 is shown in FIG. 1 with a key 2 inserted in a neutral key withdrawal position. With a rotating rod 3 at the rear end of the lock cylinder 1, a nut 4 rotatably mounted in a door plate is coupled, via which a door lock can be mechanically locked in a known manner via levers which are not visible here. Preferably can e.g. B. a door pull handle from the lock or from the lifting mechanism for a lock latch pawl when the nut 4 was rotated into the locking position. For turning the key 2 back into the key withdrawal position, a freewheel between the nut 4 and the lock cylinder 1 is usually provided ("key backlash"). The lock cylinder 1 can be returned to the key withdrawal position with a torsion spring.
The nut 4 carries a cam 5 on its outer upper circumference.

Wie aus Figur 2 ersichtlich ist, stellt der Nocken 5 eine Wirkverbindung zwischen dem Schließzylinder 1 und einem elektrischen (Mikro-)Schalter 6 mit Zuleitung 6L dar, dessen Schaltwippe 7 durch den Nocken 5 bei Drehung des Schließzylinders im Uhrzeigersinn (ausgehend von der Schlüsselabzugstellung) heruntergedrückt wird und einen Schaltstößel 8 betätigt, der im Schalter 6 einen Schaltkontakt schließt. Ferner ist hier noch ein Hebel 9 an der Nuß 4 angedeutet, an den das erwähnte Verriegelungsgestänge angelenkt werden kann. Der Hebel 9 liegt in einer anderen Ebene als die Schaltwippe 7 und kann nicht auf diese einwirken.As can be seen from FIG. 2 , the cam 5 represents an operative connection between the locking cylinder 1 and an electrical (micro) switch 6 with supply line 6L, the rocker switch 7 of which is actuated by the cam 5 when the locking cylinder rotates clockwise (starting from the key withdrawal position) is pressed down and actuates a switching plunger 8, which closes a switching contact in the switch 6. Furthermore, a lever 9 is indicated on the nut 4, to which the locking linkage mentioned can be articulated. The lever 9 lies in a different plane than the rocker switch 7 and cannot act on it.

Gemäß dem schematischen Schaltbeispiel nach Figur 3 ist der Schalter 6 einpolig und festkontaktseitig mit Masse verbunden. Sein Schaltkontakt ist über ein Zeitglied 10 an eine Schalteinrichtung 11 angeschlossen, die - stark vereinfacht dargestellt - zur Steuerung eines üblichen Türantriebselements 12 dient, das z. B. als Hubkolben-Wandermutter-Antrieb ausgeführt sein kann. Die üblicherweise in diesen Anlagen verwendeten Ventile, Druckerzeuger etc. sind hier der Übersichtlichkeit halber nicht dargestellt.
Abweichend von der figürlichen Darstellung kann natürlich auch ein umkehrbarer hydraulischer oder elektrischer Türantrieb verwendet werden. Hingegen sind weitere Steuereingänge der Schalteinrichtung 11 wenigstens angedeutet, an die z. B. ein am Fahrerplatz angeordneter Fahrertaster angeschlossen werden kann. Ferner kann die Schalteinrichtung 11 einen Eingang für ein Rückmeldesignal des Türzustands (offen / geschlossen) und einen Eingang für ein Einklemmsicherungssignal (Antriebsreversierung) haben.According to the schematic circuit example according to FIG. 3 , the switch 6 is single-pole and has a fixed contact on the ground side. His switching contact is connected via a timer 10 to a switching device 11, which - shown in a highly simplified manner - is used to control a conventional door drive element 12 which, for. B. can be designed as a reciprocating traveling nut drive. The valves, pressure generators etc. normally used in these systems are not shown here for the sake of clarity.
Deviating from the figurative representation, a reversible hydraulic or electric door drive can of course also be used. In contrast, further control inputs of the switching device 11 are at least indicated, to which, for. B. a driver button arranged at the driver's station can be connected. Furthermore, the switching device 11 can have an input for a feedback signal of the door state (open / closed) and an input for a jamming safety signal (drive reversing).

Das Zeitglied 10 hat eine signalverzögernde Wirkung, d. h. die Schalteinrichtung 11 kann den Türantrieb nur mit zeitlichem Verzug gegenüber der tatsächlichen Erzeugung eines Schaltsignals am Schalter 5 aktivieren. Es versteht sich, daß das Zeitglied an sich auch in die Schalteinrichtung 11 integriert werden kann.
Diese Anordnung hat den Vorteil, daß die mechanische Türentriegelung bereits vor der Druckbeaufschlagung des Türantriebs vollzogen ist, so daß weder ein durch dessen Öffnungsdruck verursachtes Verklemmen der Schloßmechanik noch ein plötzliches Aufprallen des Türblatts nach mechanischer Freigabe vorkommen kann. Sollte der (pneumatische) Türantrieb ohnehin relativ träge ansprechen, so kann das Zeitglied aber auch weggelassen werden.The timing element 10 has a signal-delaying effect, ie the switching device 11 can only activate the door drive with a time delay compared to the actual generation of a switching signal at the switch 5. It goes without saying that the timing element per se can also be integrated into the switching device 11.
This arrangement has the advantage that the mechanical door unlocking is carried out before the door drive is pressurized, so that neither a jamming of the lock mechanism caused by its opening pressure nor a sudden impact of the door leaf after mechanical release can occur. If the (pneumatic) door drive responds relatively sluggish anyway, the timer can also be omitted.

Die Nuß 4 liegt hier in einer Flucht mit dem deshalb nicht sichtbaren Schließzylinder 1, der nur durch Andeutung seines Schlüssellochs 1L, gestrichelt in der Schlüsselabzugstellung und strichpunktiert in um 90° verdrehter Stellung gezeichnet, repräsentiert ist.The nut 4 lies here in alignment with the locking cylinder 1, which is therefore not visible, and which is represented only by hinting at its keyhole 1L, dashed lines in the key withdrawal position and dash-dotted lines in a position rotated by 90 °.

Gegenüber dem Nocken 5 trägt die Nuß nun in einer vorteilhaften Weiterentwicklung auf ihrem unteren Umfang noch einen weiteren Nocken 13, der aber in einer axial gegenüber der Ebene des Nokken 5 versetzten Ebene liegt und eine Wirkverbindung des Schließzylinders 1 mit einem weiteren elektrischen Schalter 14 bildet. Letzterer kann daher nur durch Schlüsseldrehung des Schließzylinders im Verriegelungssinn geschaltet werden, welche Drehung, wie erwähnt, mit einer mechanischen Verriegelung des Türschlosses einhergeht.Compared to the cam 5, in an advantageous further development, the nut now carries a further cam 13 on its lower circumference, which, however, lies in a plane axially offset from the plane of the cam 5 and forms an operative connection of the locking cylinder 1 with a further electrical switch 14. The latter can therefore only be switched by turning the lock cylinder in the locking direction, which Rotation, as mentioned, is associated with a mechanical locking of the door lock.

Der Schaltkontakt des ebenso wie der Schalter 6 einseitig an Masse liegenden einpoligen Schalters 14 ist mit einer Zentralverriegelungsanlage 15 verbunden, präziser mit deren Steuergerät 15S, welchem wiederum in bekannter Weise Stellelemente 15E zur gleichzeitigen Ent- bzw. Verriegelung mehrerer Schlösser zugeordnet sind, so daß bei Verriegelung des dem Schließzylinder 1 zugeordneten Schlosses - das in der Regel auf der Passagiereinstiegsseite vorn angeordnet ist - die weiteren Schlösser über die Stellelemente 15E in gleicher Weise gesichert werden können. Eine weitere Bedienstelle für die Zentralverriegelung kann sich auf der Fahrerseite in einem der Fahrertür zugeordneten Schließzylinder befinden.The switch contact of the single-pole switch 14, which is also connected to ground on one side and the switch 6, is connected to a central locking system 15, more precisely to its control unit 15S, which in turn is assigned control elements 15E for the simultaneous unlocking or locking of a plurality of locks, so that at Locking the lock assigned to the lock cylinder 1 - which is usually arranged on the passenger entry side at the front - the other locks can be secured in the same way via the actuating elements 15E. Another control point for the central locking system can be located on the driver's side in a lock cylinder assigned to the driver's door.

An einen anderen Eingang des Steuergeräts 15S ist nun auch der Schaltkontakt des Schalters 6 angeschlossen. Ergänzend zu der dargestellten vereinfachten Anordnung sei angemerkt, daß mit den beiden Steuerschaltern 6 und 14 elektrische Magnetventile gesteuert werden können, über welche die reversierbaren Stellelemente an Luftdruck anschließbar sind. Zusätzlich können diese Schalter natürlich auch in an sich bekannter Weise zur Steuerung einer Alarmanlage oder sonstiger Einbruchsicherungssysteme verwendet werden.The switch contact of the switch 6 is now also connected to another input of the control device 15S. In addition to the simplified arrangement shown, it should be noted that the two control switches 6 and 14 can be used to control electrical solenoid valves, via which the reversible control elements can be connected to air pressure. In addition, these switches can of course also be used in a manner known per se for controlling an alarm system or other burglar alarm systems.

Die gezeigte Anordnung funktioniert wie folgt:
Wenn der Schließzylinder 1 bei geschlossener und verriegelter Tür mit dem Schlüssel 2 im Entriegelungssinn gedreht wird, so wird

  • a) das zugeordnete Türschloß mechanisch entriegelt,
  • b) der Türantrieb 12, ggf. mit einer gewissen zeitlichen Verzögerung durch das Zeitglied 10, im Öffnungssinn durch die Schalteinrichtung 11 aktiviert,
  • c) die Zentralverriegelungsanlage 15 über das Steuergerät 15S im Entriegelungssinn zur Entriegelung aller angeschlossenen Verschlüsse mittels der Stellelemente 15E betrieben.
The arrangement shown works as follows:
If the lock cylinder 1 is turned with the key 2 in the unlocking direction while the door is closed and locked, then
  • a) mechanically unlocks the assigned door lock,
  • b) the door drive 12, possibly with a certain time delay by the timer 10, in the opening direction by the Switching device 11 activated,
  • c) the central locking system 15 is operated via the control unit 15S in the unlocking direction for unlocking all connected locks by means of the adjusting elements 15E.

Wird der Schließzylinder 1 bei geschlossener, entriegelter Tür mit dem Schlüssel 2 im Verriegelungssinn gedreht, so wird

  • a) das zugeordnete Türschloß mechanisch verriegelt und
  • b) die Zentralverriegelungsanlage 15 über das Steuergerät 15S im Verriegelungssinn zur Verriegelung aller angeschlossenen Verschlüsse mittels der Stellelemente 15E betrieben.
If the lock cylinder 1 is turned with the key 2 in the locking direction when the door is closed and unlocked, then
  • a) the associated door lock mechanically locked and
  • b) the central locking system 15 is operated via the control unit 15S in the locking direction for locking all connected closures by means of the actuating elements 15E.

Bei Schlüsselbetätigung des Schließzylinders 1 im Entriegelungssinn bei geöffneter Tür (hierbei ist entriegelter Zustand des Türschlosses die Regel) wird nur der Türantrieb 12 über die Schalteinrichtung 11 im Türschließsinne aktiviert, ggf. wiederum mit einer bestimmten zeitlichen Verzögerung.When the key cylinder 1 is actuated in the unlocking direction when the door is open (here the unlocked state of the door lock is the rule), only the door drive 12 is activated via the switching device 11 in the door closing direction, possibly again with a certain time delay.

Es kann wahlweise vorgesehen werden, daß bei Drehung des Schließzylinders bei geöffneter Tür im Verriegelungssinn eine zentrale Verriegelung der weiteren Türschlösser durchgeführt wird oder unterbleibt. Soll eine mechanische Verriegelung des zugeordneten Türschlosses bei offener Tür verhindert werden, so wäre eine an sich bekannte Vorverriegelungssperre - Sperre gegen Verriegelung der noch offenstehenden Tür - vorzusehen.It can optionally be provided that when the lock cylinder is rotated with the door open, a central locking of the further door locks is carried out or is omitted. If a mechanical locking of the assigned door lock is to be prevented when the door is open, a pre-locking lock known per se - locking against locking of the still open door - would have to be provided.

Wie beim Fahrertasterbetrieb kann bei Bedarf auch mittels der Schaltsignale des Schalters 6 ein laufender Öffnungs- oder Schließvorgang des Türantriebs umgekehrt werden.As in driver button operation, an ongoing opening or closing process of the door drive can also be reversed if necessary by means of the switching signals of the switch 6.
