Description

Die Erfindung bezieht sich auf ein mit einem Türfeststeller baulich Vereinigtes Türscharnier, insbesondere ein um einen Öffnungswinkel von mehr als 90° verschwenkbares Türscharnier, bestehend aus zwei vermittels eines Scharnierstiftes drehbar miteinander verbundenen Scharnierflügeln und einem am einen Scharnierflügel angeordneten Widerlagerelement sowie einem am anderen Scharnierflügel angeordneten federbelasteten Rastmittel, wobei das im Bereich eines Scharnierauges angeordnete und drehsicher bzw. einteilig mit dem einen Scharnierflügel ausgebildete Widerlagerelement wenigstens eine quer zur Scharnierachse ausgerichtete Rastausnehmung aufweist und wobei ferner das insbesondere als Riegel ausgebildete Rastmittel durch gegeneinander Verschwenkung der Scharnierflügel gegen eine Federlast radial zum Widerlagerelement aus der Rastausnehmung verstellbar und am anderen Scharnierflügel gelagert ist und wenigstens einen mit dem Widerlagerelement zusammenwirkenden beidseitig und symetrisch abgeschrägten Eingriffszahn aufweist.The invention relates to a door hinge which is structurally united with a door arrester, in particular a door hinge which can be pivoted by an opening angle of more than 90 °, consisting of two hinge wings rotatably connected to one another by means of a hinge pin and an abutment element arranged on one hinge wing and a spring-loaded spring arranged on the other hinge wing Locking means, wherein the arranged in the area of a hinge eye and non-rotatably or integrally formed with the one hinge wing abutment element has at least one locking recess oriented transversely to the hinge axis and furthermore the locking means, in particular designed as a bolt, by pivoting the hinge wings against one another radially to the abutment element from the Adjustable recess and is mounted on the other hinge wing and at least one interacting with the abutment element on both sides and syme has trically beveled engagement tooth.

Türscharniere mit einem großen, mehr als 90° betragenden Öffnungswinkel werden insbesondere zur Anlenkung der Hecktüren von Nutzfahrzeugen verwendet, wobei es sich regelmäßig um schwere Türen handelt, deren sichere Feststellung in einer beabsichtigten Öffnungslage eine formschlüssige Verriegelung verlangt. Für solche Türen ist bereits ein mit dem Türscharnier baulich vereinigter Türfeststeller der vorgenannten Bauart vorgeschlagen worden. Charakteristisch für derartige Türfestseller ist der Umstand, daß das am einen Scharnierflügel angeordnete Rastmittel bzw. Riegelglied ausschließlich unter Federlast mit den zugehörigen Widerlagermitteln am anderen Scharnierflügel in Eingriff gelangt bzw. gehalten ist, wobei die Haltewirkung des Rastmittels bzw. Riegelgliedes begrenzt sein muß, um ein beabsichtigtes Öffnen oder Schließen der Tür zu ermöglichen. Aus dem Umstand, daß das Rastmittel oder Riegelglied beim Auftreten einer bestimmten am Türflügel angreifenden Kraft, insbesondere entgegen seiner Federbelastung aus der Verrastung mit den Widerlagermitteln ausrücken muß resultiert der Nachteil, daß die jeweilige Tür in jedem Falle nur bis zu einer gewissen Haltewirkung gegen ein Weiterbewegen verriegelbar ist. In manchen Fällen ist es aber erwünscht die Tür willkürlich gegen ein Weiterbewegen in wenigstens einer Bewegungsrichtung, vorzugsweise der Öffnungsrichtung, absolut sicher festlegen zu können, beispielsweise um jede Gefährdung von Passanten beim Be-oder Entladen des Fahrzeuges auf der Straße mit Sicherheit ausschließen zu können. Bei einer anderen, aus der GB-A-2155 540 bekannten Bauart eines mit einem Türscharnier baulich vereinigten Türfeststellers für Hecktüren von Nutzfahrzeugen ist ein als Kipphebel ausgebildetes, am einen Scharnierflügel um eine zur Scharnierachse parallele Achse schwenkbar gelagertes Rastglied vorgesehen, welches mittels einer an seinem einen Hebelarm angreifenden Druckfeder in Einrückrichtung federbelastetes ist und welches über seinen anderen Hebelarm mit am anderen Scharnierflügel angeordneten Widerlagerrasten zusammenwirkt. In Verbindung mit einer V-förmigen Querschnittsform der Widerlagerrasten am anderen Scharnierflügel ist dabei das freie Ende des mit diesen zusammenwirkenden Hebelarmes des Kipphebels als spitzwinkeliger Eingriffszahn ausgebildet, so daß sich beim Einlaufen des Kipphebelarmes in eine der Widerlagerrasten eine Arretierung der Türe ergibt, welche nur durch manuelles Ausheben des Kipphebels aufgehoben werden kann. Bauartbedingt eignen sich solche mit einem Türscharnier vereinigte Türfeststeller nur zur Abstützung begrenzter Kräfte und sind darüberhinaus mit dem Nachteil eines verhältnismäßig großen Bedarfes an Einbauraum behaftet.Door hinges with a large opening angle of more than 90 ° are used in particular for articulating the rear doors of commercial vehicles, which are regularly heavy doors, the secure locking of which in an intended opening position requires a positive locking. A door arrester of the aforementioned type, which is structurally combined with the door hinge, has already been proposed for such doors. Characteristic of such door locks is the fact that the latching means or locking element arranged on one hinge wing comes into engagement or is held only under spring load with the associated abutment means on the other hinge wing, the holding action of the locking means or locking member having to be limited to a to allow intended opening or closing of the door. From the fact that the locking means or bolt member when a certain force acting on the door leaf occurs, in particular against its spring load, must disengage from the latching with the abutment means that the disadvantage results that the respective door can only be locked against further movement to a certain holding effect. In some cases, however, it is desirable to be able to arbitrarily secure the door against further movement in at least one direction of movement, preferably the opening direction, for example in order to be able to exclude with certainty any risk to passers-by when loading or unloading the vehicle on the road. In another design known from GB-A-2155 540 of a door arrester for rear doors of commercial vehicles that is structurally combined with a door hinge, a locking member designed as a rocker arm is provided on a hinge wing that is pivotably mounted about an axis parallel to the hinge axis, which is provided by means of a latch on its a compression spring engaging a lever arm is spring-loaded in the direction of engagement and which interacts via its other lever arm with abutment catches arranged on the other hinge wing. In conjunction with a V-shaped cross-sectional shape of the abutment catches on the other hinge wing, the free end of the lever arm of the rocker arm interacting with this is designed as an acute-angled engagement tooth, so that when the rocker arm engages in one of the abutment catches, the door locks, which only results from manual lifting of the rocker arm can be lifted. Due to their design, door locks combined with a door hinge are only suitable for supporting limited forces and, moreover, have the disadvantage of a relatively large amount of installation space.

Der Erfindung liegt daher die Aufgabe zugrunde für ein mit einem Türfeststeller baulich vereinigtes Türscharnier mit einem großen, mehr als 90° betragenden Öffnungswinkel eine zusätzliche Arretierung für die Türe zu schaffen, durch welche der an sich bereits erforderliche Einbauraum für das Scharnier nicht vergrößert wird und welche manuell einschaltbar ist und einerseits einen geringstmöglichen Herstellungsaufwand erfordert, andererseits aber eine absolut sichere Arretierung einer schweren Tür, insbesondere der Tür eines Nutzfahrzeuges, in mehreren Öffnungslagen in solcher Weise gewährleistet, daß ein unbeabsichtigtes, beispielsweise durch Berühren oder Anstoßen der Tür bedingtes bzw. ausgelöstes Aufschlagen der Tür verhindert wird.The invention is therefore based on the object for a structurally combined with a door arrester door hinge with a large, more than 90 ° opening angle to create an additional locking device for the door, through which the installation space required for the hinge itself is not enlarged and which can be switched on manually and on the one hand requires the least possible production outlay, but on the other hand ensures absolutely secure locking of a heavy door, in particular the door of a commercial vehicle, in several opening positions in such a way that unintentional, for example by touching or bumping the door conditional or triggered opening of the door is prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Türscharnier eine Arretiereinrichtung aufweist, die aus einem federbelasteten längsverschieblichen, in der einen Richtung lediglich manuell ausrückbaren zusätzlich zu dem Rastmittel angeordneten Riegel besteht, dessen Eingriffszahn unsymetrisch gestaltet und lediglich einseitig abgeschrägt ist.
Ein solcher in einer Richtung lediglich manuell d.h. willkürlich verschiebbarer Riegel Rastmittel ermöglicht es auf der einen Seite die Tür in einer oder meheren vorgegebenen Öffnungslagen gegen jede weitere Bewegung in Öffnungsrichtung zu sichern und beläßt dabei die Möglichkeit, die Tür in der bei mit einem Türfeststeller herkömmlicher Bauart ausgerüsteten Türen üblichen Weise zu schließen.This object is achieved in that the door hinge has a locking device which consists of a spring-loaded, longitudinally displaceable, in one direction only manually disengaged in addition to the locking means arranged latch, the engagement tooth is asymmetrical and is only beveled on one side.
Such a latching means which can only be moved manually in one direction, that is to say arbitrarily, enables the door to be secured on one side in one or more predetermined opening positions against any further movement in the opening direction and thereby leaves the possibility of having the door in the conventional design with a door arrester equipped doors to close the usual way.

Bei entsprechender Ausgestaltung zeichnet sich dieses um eine Arretiereinrichtung erweiterte Türscharnier auch noch dadurch aus daß es mit einem geringstmöglichen Aufwand realisierbar ist und die Einheit insgesamt keinen größeren Bedarf an Einbauraum hat, als ein herkömmliches mit einem Türfeststeller baulich vereinigtes Türscharnier. Gleichzeitig gewährleistet die erfindungsgemäße Arretiereinrichtung aber auch eine absolut sichere, formschlüssige Verriegelung der Tür in ihrer jeweils festgestellten Öffnungslage, so daß, wie dies bei Türen von Nutzfahrzeugen des öfteren vorkommen kann, ein Berühren oder Anstoßen der Tür in wenighstens einer Bewegungsrichtung nicht zum Lösen ihrer Verriegelung führen kann.With a corresponding design, this door hinge extended by a locking device is also characterized in that it can be realized with the least possible effort and the unit as a whole has no greater need for installation space than a conventional door hinge structurally combined with a door arrester. At the same time, the locking device according to the invention also ensures an absolutely secure, positive locking of the door in its respectively determined opening position, so that, as can often happen with doors of commercial vehicles, touching or bumping the door in at least one direction of movement does not solve it their locking can result.

Gemäß einer ersten bevorzugten Ausführungsform ist vorgesehen, daß die Rastausnehmungen im Widerlagerelement ein unsymetrisch gestaltetes Querschnittsprofil aufweisen, wobei die der Verriegelung der einen Bewegungsrichtung,z.B. der Öffnungsbewegung der Tür zugeordnete Wandungsfläche senkrecht zur Scharnierachse und die der Verriegelung der anderen Bewegungsrichtung, z.B. der Schließbewegung der Tür zugeordnete Wandungsfläche schräg zur Scharnierachse ausgerichtet ist.According to a first preferred embodiment it is provided that the locking recesses in the abutment element have an asymmetrically designed cross-sectional profile, the locking of one direction of movement, e.g. the wall area assigned to the opening movement of the door perpendicular to the hinge axis and that to the locking of the other direction of movement, e.g. the closing movement of the door wall surface is oriented obliquely to the hinge axis.

Der lediglich einseitig mit einer Abschrägung versehene Eingriffszahn des in einer Richtung manuell verschiebbaren Riegels gewährleistet in Verbindung mit einer zur Scharnierachse senkrechten Anordnung der einen Wandungsfläche der Rastausnehmungen im Widerlagerelement, daß eine Bewegung der Tür in einer Bewegungsrichtung, insbesondere der Öffnungsrichtung, mit Hilfe des manuell verschiebbaren Riegels sicher gesperrt werden kann, wobei auch ein Ausrücken der Sperre durch Überwinden der den Riegel beaufschlagenden Federlast nicht möglich ist.The engagement tooth of the latch, which can be moved manually in one direction, is provided with a bevel only on one side, and in conjunction with an arrangement of the one wall surface of the latching recesses in the abutment element perpendicular to the hinge axis, ensures that movement of the door in one direction of movement, in particular the opening direction, with the aid of the manually displaceable one Bolt can be locked securely, and disengagement of the lock by overcoming the spring load acting on the bolt is not possible.

In einer, weil extrem raumsparend unterbringbaren besonders bevorzugten konstruktiven Ausgestaltung ist vorgesehen, daß das Widerlagerelement durch die mit entsprechenden längsgerichteten Profilausnehmungen versehene Kopfrolle des anderen Scharnierflügels gebildet ist und beide Rastmittel durch zueinander parallel ausgerichtet angeordnete längsverschiebbare Riegel mit zylindrischem Schaftteil gebildet sind sowie der die Rastmittel tragende Scharnierflügel als gehäuseartiges Formteil, insbesondere Gußteil, ausgebildet ist und in einander gegenüberliegenden, parallel zur Scharnierachse gerichteten Stegwandungen Aussparungen für die Abstützung und Führung der die Rastmittel bildenden Riegel aufweist. Zweckmäßigerweise ist die Gestaltung ferner so getroffen, daß der Eingriffszahn des manuell verschiebbaren Riegels ein im wesentlichen kreisrunden und der Eingriffszahn des unter Federlast selbsttätig einrückenden Riegels eine abgerundete rechteckige Querschnittsform aufweist und beide Eingriffszähne in einer jeweils entsprechend geformten Erweiterung einer der Scharnierachse benachbarten, zu dieser parallel gerichteten Stegwandung des Scharnierflügels geführt sind.In a particularly preferred constructive embodiment, which can be accommodated in an extremely space-saving manner, it is provided that the abutment element is formed by the head roller of the other hinge wing provided with corresponding longitudinal profile recesses, and both latching means are formed by longitudinally displaceable latches with a cylindrical shaft part arranged parallel to one another and the one carrying the latching means Hinge wing is designed as a housing-like molded part, in particular a cast part, and has cutouts for supporting and guiding the latches forming the latching means in web walls opposite one another and oriented parallel to the hinge axis. Expediently, the design is also such that the engagement tooth of the manually displaceable bolt is essentially circular and the engagement tooth of the bottom Spring load automatically engaging bolt has a rounded rectangular cross-sectional shape and both engagement teeth are guided in a correspondingly shaped extension of one of the hinge axis adjacent to the hinge axis and parallel web wall of the hinge wing.

Der unter Federlast einrückende Riegel des Türfeststellers ist vorzugsweise durch eine an der quergerichteten Stegwandung des Scharnierflügels abgestützte und vermittels eines an dessen Schaftteil festgelegten Federtellers an ihm angreifenden Schraubentellerfeder belastet, während der manuell verschiebbare Riegel vorzugsweise durch eine an der gleichen quergerichteten Stegwandung des Scharnierflügels abgestützte und vermittels eines an dessen Schaftteil angeordneten Federtellers an ihm angreifenden Schraubenfeder belastet ist.The latch of the door arrester, which engages under spring load, is preferably loaded by a screw plate spring which is supported on the transverse web wall of the hinge wing and engages on it by means of a spring plate fixed to its shaft part, while the manually displaceable latch is preferably supported and mediated on the same transverse web wall of the hinge wing a spring plate arranged on its shaft part is loaded on the coil spring acting on it.

Gemäß einer anderen Verwirklichungsform der Erfindung kann ferner auch vorgesehen sein, daß wenigstens einer der die Rastmittel bildenden Riegel als Schwenkriegel ausgebildet und um einen quer zur Scharnierachse gerichtete Achse schwenkbar am einen Scharnierflügel gelagert ist.According to another embodiment of the invention, it can also be provided that at least one of the latches forming the latching means is designed as a swivel latch and is pivotably mounted on a hinge wing about an axis directed transversely to the hinge axis.
