Abstract

The driving cabin of a truck has an outside-swinging door mounted on a pivoted column, driven by a pneumatic motor. The door lock is operated by a separate electric servomotor with an eccentric driven member and drive rod. This rod is connected by a pivot to a double lever whose free ends are linked to locking rods. The locking rods are cranked so that their other ends can slide horizontally in bearings, projecting through these into openings in the door frame. The drive rod comprises a cylinder with piston, piston rod and internal spring. A bush on the side of the cylinder contains a peg for manual operation of the rod should the electric motor fail.

Description

Die Erfindung bezieht sich auf ein Fahrerhaus eines Lastkraftwagens mit einer an einer drehbaren Säule des Türrahmens angeordneten, von einem Pneumatikmo­ tor angetriebenen Außenschwingtür und einer Türverriegelung.The invention relates to a cab of a truck with a a rotatable column of the door frame arranged by a pneumatic mo Tor driven outer swing door and a door lock.

Anordnungen dieser Art sind in den manigfaltigsten Ausführungsformen be­ kannt.Arrangements of this type are in the most varied embodiments knows.

Der Erfindung liegt die Aufgabe zugrunde eine Türsicherung einfacher Art mit erhöhtem Sicherheitsstandard zu schaffen.The invention has for its object a simple type of door security to create increased security standards.

Dies wird erfindungsgemäß dadurch erreicht, daß für die Türverriegelung ein se­ parater elektrischer Stellmotor mit einem exzentrischen Abtriebsglied vorgese­ hen ist, dessen Schubstange mit einem Doppelhebel gelenkig verbunden ist, an dessen freien Enden Verriegelungsstangen angelenkt sind, die in Lagern gleitbar gehalten sind und deren Kopfteile in Horizontalerstreckung in Öffnungen des Türrahmens einführbar sind. Solcherart wird ein Verriegelungssystem geschaffen, daß von der Drehbewegung der Außenschwingtür in keiner direkten Abhängig­ keit steht und das über ein eigenes Antriebssystem, vorzugsweise elektrischer Art, von jedem Punkt des Wagens aus steuerbar ist. Diese Art von Sicherung schließt ein von außen gewaltsames Öffnen des Fahrzeuges völlig aus.This is achieved according to the invention in that a se for the door locking ready electric actuator with an eccentric output element hen is, the push rod is articulated with a double lever on the free ends of which are articulated locking rods that can slide in bearings are held and the head parts in horizontal extension in openings of the Door frames are insertable. Such a locking system is created that in no direct dependence on the rotational movement of the outer swing door speed is available and this via its own drive system, preferably electrical Kind that is controllable from every point of the car. That kind of backup completely excludes a violent opening of the vehicle from the outside.

Die Unteransprüche betreffen die detailliertere Ausbildung der Schubstange, und zwar der Art, daß bei Ausfall des Stellmotors oder einer elektrischen Steuerungs­ komponente über Seilzug die Türverriegelung auch von Hand ausrastbar ist.The subclaims relate to the more detailed design of the push rod, and the type that in the event of failure of the servomotor or an electrical control component, the door lock can also be manually disengaged using a cable.

Die Drehbewegung der Außenschwingtür und der Verriegelungsmechanismus werden durch elektrische oder pneumatische Steuermittel koordiniert, so daß die Türdrehbewegung erst verzögert nach der Entriegelung eingeleitet wird, wäh­ rend die Verriegelung erst dann erfolgt, wenn die Tür sich schließend in den Tür­ rahmen eingepaßt hat.The rotation of the outer swing door and the locking mechanism are coordinated by electrical or pneumatic control means so that the Door turning movement is only delayed after unlocking, wäh The locking only takes place when the door closes in the door frame has fitted.

Die Erfindung ist in einem Ausführungsbeispiel dargestellt und beschrieben. The invention is illustrated and described in an exemplary embodiment.

Fig. 1 zeigt eine in einem Türrahmen 1 eines Fahrerhauses angeordnete Außen­ schwingtür 2. Die Außenschwingtür 2 ist um eine drehbare Säule 3 angeordnet, die von einem Pneumatikmotor 4 antreibbar ist. Es ist eine separate Türverriege­ lung 5 vorgesehen, deren Kernstück der vorzugsweise elektrisch angetriebene Stellmotor 6 ist. Das Abtriebsglied 7 des Stellmotors 6 ist exzentrisch ausgebildet und gelenkig mit einer Schubstange 8 verbunden, die gelenkig an einem Doppel­ hebel 9 angreift, der im Drehpunkt 10 an der Tür 2 drehbar gelagert ist. An den freien Enden 11, 11′ des Doppelhebels 9 sind Verriegelungsstangen 13 und 12 an­ gelenkt, die in Lagern 16 und 16′ gleitbar gehalten sind. Die Kopfteile 14 und 15 der Verriegelungsstangen 12 und 13 können bei entsprechender Betätigung des Stellmotors in Öffnungen 17 und 17′ des Türrahmens 1 eingeführt werden, so daß die Außenschwingtür mit dem Rahmen sicher verriegelt ist. Fig. 1 shows a arranged in a door frame 1 of a cab exterior swinging door 2. The outer swing door 2 is arranged around a rotatable column 3 which can be driven by a pneumatic motor 4 . There is a separate Türverriege development 5 , the core of which is preferably the electrically driven actuator 6 . The output member 7 of the servomotor 6 is eccentric and articulated with a connecting rod 8 which articulates on a double lever 9 which is rotatably mounted on the door 2 at the pivot point 10 . At the free ends 11 , 11 'of the double lever 9 locking rods 13 and 12 are steered on, which are slidably held in bearings 16 and 16 '. The head parts 14 and 15 of the locking rods 12 and 13 can be inserted into openings 17 and 17 'of the door frame 1 with appropriate actuation of the servomotor, so that the outer swing door is securely locked to the frame.

Fig. 2 zeigt die detaillierte Ausbildung der Schubstange 8. Sie ermöglicht, daß bei Ausfall von elektrischen Komponenten die Entriegelung der Tür auch von Hand durchführbar ist. Die Schubstange 8 besteht aus einem Zylinder 18 mit einem ein­ seitigen Boden 21. Im offenen Ende des Zylinders 18 ist der Kolbenteil 19 mit An­ schlußgelenk fest angeordnet. Im Zylinder ist der Kolbenteil 20 mit der Kolben­ stange 27 mit Anschlußgelenk gleitbar angeordnet. Zwischen Kolbenteil 19 und Kolbenteil 20 ist eine vorgespannte Druckfeder 23 angeordnet. Auf der Gehäuse­ wand des Zylinders 18 ist in Höhe des Kolbenteils 20 eine Buchse 24 befestigt, in der ein Stift 22 geführt ist, der über eine Feder 26 in einer Rasterung des Kolbens 20 gedrückt ist und diesen solcherart in eine feste Position hält. Soll die elektri­ sche Betätigung der Türverriegelung außer Kraft gesetzt werden, so wird über ei­ nen Seilzug 25 von Hand gegen die Kraft der Feder 26 der Stift 22 aus der Verrasterung herausgezogen, wobei gleichzeitig über Wirksamsetzung der Druckfeder 23 der gleitbare Kolben 20 gegen die Zylinderwand 21 gedrückt wird. Auf diese Weise wird die Schubstange 8 verlängert, was zur Folge hat, daß die Verriegelungsstangen 12 und 13 aus den Öffnungen 17 und 17′ ausgefahren wer­ den. Fig. 2 shows the detailed construction of the push rod 8. It enables the door to be unlocked by hand if electrical components fail. The push rod 8 consists of a cylinder 18 with a one-sided bottom 21st In the open end of the cylinder 18 , the piston part 19 is fixedly arranged at the joint. In the cylinder, the piston part 20 is slidably arranged with the piston rod 27 with connecting joint. A prestressed compression spring 23 is arranged between piston part 19 and piston part 20 . On the housing wall of the cylinder 18 , a bushing 24 is fastened at the level of the piston part 20 , in which a pin 22 is guided, which is pressed by a spring 26 in a grid of the piston 20 and holds it in such a way in a fixed position. If the electrical cal actuation of the door lock is to be overridden, then the pin 22 is pulled out of the catch via a cable 25 by hand against the force of the spring 26 , while at the same time the slidable piston 20 against the cylinder wall 21 is activated via the compression spring 23 is pressed. In this way, the push rod 8 is extended, with the result that the locking rods 12 and 13 from the openings 17 and 17 'extended who.
