Definitions
- the present invention relates to a locking mechanism for a door, in particular for a vehicle door, comprising at least one locking element for locking the door in a closed position and an actuating device for user-side transfer of the locking element from a locking position to an unlocking position and / or from the unlocked position to the locking position wherein the locking element and the actuating device are mechanically coupled to one another by means of a tension-pressure element.
- Such locking mechanisms are well known, especially from the vehicle sector. They have a centrally mounted on a door and externally actuated by a user actuating device usually in the form of a pull handle. On the inside, one or two locking units are arranged at a distance from the actuating device, for example above or below the actuating device. These are each technically connected via a generally metallic tension rod with the actuating unit, such that the user-side actuation causes a relative positioning of the tension rods. A change in position of the respective tie rod is transmitted via a rotatable cam member to a locking element of the locking units. As a result, the latch member is displaced between a door locking position and a door unlocking position.
- the coupling of the tension rod and the cam element is simple in the form of an opening formed in the cam element, in which engages the pull rod.
- Such a mechanism works reliably and properly with the appropriate length of the tie rod and appropriate arrangement of the parts interacting therewith.
- the length of the tension rod does not lie in a sufficiently small tolerance field or if wear occurs over time on the cams, which are usually designed as injection-molded plastic parts, changes in the position of the locking elements can occur as intended No longer be guaranteed and malfunctions will occur.

- a door in the narrower sense for entering or leaving a room closed by the door also has similar closure elements positionable between a closed position and an open position, such as windows, flaps, tailboards, hatches, etc.
- the coupling mechanism is preferably easily accessible even in the assembled state and advantageously allows a defined, reliable and above all reproducible way to adjust the locking mechanism during its assembly and readjust in case of wear as well. This eliminates the need to adjust by manually bending the tie rod so that it is not weakened as a result of deformation and also no misalignments or tilting are introduced into the mechanism.
- a particular advantage is that also hidden and moved inside the door latch mechanisms can be switched on or after.
- the latch mechanism may include two or more latch units operatively connected to the actuator spaced apart from one another and from the actuator at different positions on the door so as to lock the door to a door frame, frame, or door lock at different locations to care.

- the pivot may in one embodiment, in which the first cam member and the second cam member on opposite sides of the locking element are arranged, pass through the locking element.
- the locking mechanism according to the invention and in particular the coupling mechanism are easy to assemble and to maintain.
- a particularly easy to install option is that the pivot has an opening provided with an internal thread and is fixed in position with a screw that passes through one of the cam elements.

Description
Die vorliegende Erfindung betrifft einen Riegelmechanismus für eine Tür, insbesondere für eine Fahrzeugtür, aufweisend zumindest ein Riegelelement zur Verriegelung der Tür in einer geschlossenen Stellung und eine Betätigungseinrichtung zum nutzerseitigen Überführen des Riegelelements aus einer Verriegelungsstellung in eine Entriegelungsstellung und/oder aus der Entriegelungsstellung in die Verriegelungsstellung, wobei das Riegelelement und die Betätigungseinrichtung mittels eines Zug-Druck-Elements mechanisch miteinander gekoppelt sind.The present invention relates to a locking mechanism for a door, in particular for a vehicle door, comprising at least one locking element for locking the door in a closed position and an actuating device for user-side transfer of the locking element from a locking position to an unlocking position and / or from the unlocked position to the locking position wherein the locking element and the actuating device are mechanically coupled to one another by means of a tension-pressure element.
Derartige Riegelmechanismen sind allgemein bekannt, insbesondere aus dem Fahrzeugsektor. Sie weisen eine an zentraler Stelle an einer Tür angebrachte und von außen durch einen Nutzer zu betätigende Betätigungseinrichtung in der Regel in Form eines Zuggriffs auf. Innenseitig ist / sind beabstandet von der Betätigungseinrichtung, zum Beispiel oberhalb oder unterhalb der Betätigungseinrichtung, eine oder zwei Riegeleinheiten angeordnet. Diese sind jeweils über einen in der Regel metallischen Zugstab wirktechnisch mit der Betätigungseinheit verbunden, derart, dass deren nutzerseitige Betätigung eine Relativpositionierung der Zugstäbe bewirkt. Eine Lageänderung des jeweiligen Zugstabs wird über ein drehbares Nockenelement auf ein Riegelelement der Riegeleinheiten übertragen. Infolge dessen wird das Riegelelement zwischen einer die Tür verriegelnden Stellung und einer die Tür entriegelnden Stellung verschoben.Such locking mechanisms are well known, especially from the vehicle sector. They have a centrally mounted on a door and externally actuated by a user actuating device usually in the form of a pull handle. On the inside, one or two locking units are arranged at a distance from the actuating device, for example above or below the actuating device. These are each technically connected via a generally metallic tension rod with the actuating unit, such that the user-side actuation causes a relative positioning of the tension rods. A change in position of the respective tie rod is transmitted via a rotatable cam member to a locking element of the locking units. As a result, the latch member is displaced between a door locking position and a door unlocking position.
Insbesondere im Fahrzeugsektor, wie zum Beispiel bei Wohnmobilen, Wohnwagen sowie Pferdetransportern, ist eine robuste, leichte und kostengünstige Ausführung des Riegelmechanismus erwünscht. Aus diesem Grund ist die Kopplung von Zugstab und Nockenelement einfach in Form einer im Nockenelement ausgebildeten Öffnung ausgeführt, in die der Zugstab eingreift. Ein derartiger Mechanismus funktioniert verlässlich und bestimmungsgemäß bei passender Länge des Zugstabs und entsprechender Anordnung der damit zusammenwirkenden Teile. Liegt die Länge des Zugstabs allerdings nicht in einem ausreichend kleinen Toleranzfeld oder tritt an den meist als Kunststoffspritzgussteile ausgebildeten Nocken im Laufe der Zeit Verschleiß auf, können bestimmungsgemäße Lageänderungen der Riegelelemente nicht mehr garantiert werden und es kommt zu Fehlfunktionen. Dabei können schon geringe Abweichungen der Länge des Zugstabs oder geringer Verschleiß Hubminderung und damit Probleme beim Öffnen der Tür verursachen.Especially in the automotive sector, such as motorhomes, caravans and horse transporters, a robust, lightweight and cost effective design of the latch mechanism is desired. For this reason, the coupling of the tension rod and the cam element is simple in the form of an opening formed in the cam element, in which engages the pull rod. Such a mechanism works reliably and properly with the appropriate length of the tie rod and appropriate arrangement of the parts interacting therewith. However, if the length of the tension rod does not lie in a sufficiently small tolerance field or if wear occurs over time on the cams, which are usually designed as injection-molded plastic parts, changes in the position of the locking elements can occur as intended No longer be guaranteed and malfunctions will occur. Even small deviations in the length of the tie rod or low wear can cause a reduction in the stroke and thus problems opening the door.
Eine Möglichkeit zum Beheben derartiger Probleme besteht bei bekannten Systemen darin, die Länge des Zugstabs durch spezifisches Biegen zu erhöhen oder zu verkürzen, beispielsweise im Rahmen der Montage oder einer Reparatur. In nachteiliger Weise besteht eine solche Korrekturmöglichkeit bei verdeckten System, in denen der Zugstab zum Beispiel aus ästhetischen Gründen verdeckt im Inneren einer Türe angeordnet ist, nicht. Ein weiterer Nachteil ist, dass das in der Regel manuell durchgeführte Biegen des Zugstabs eher subjektiver Natur ist und viel Gefühl und Erfahrung bedarf.One way to overcome such problems, in known systems, is to increase or shorten the length of the tie rod by means of specific bending, for example during assembly or repair. Disadvantageously, such a correction possibility does not exist in the case of a concealed system in which the tension rod is concealed, for example for reasons of aesthetics, inside a door. Another disadvantage is that the usually manually performed bending of the tension rod is rather subjective in nature and requires a lot of feeling and experience.
In Anbetracht des vorstehend beschriebenen Stands der Technik liegt der Erfindung die Aufgabe zugrunde, die genannten Nachteile zu verringern oder zu vermeiden, insbesondere einen Riegelmechanismus mit einer leichten, kostengünstigen und robusten Möglichkeit zum Einstellen und/oder Nachstellen zur Verfügung zu stellen.In view of the state of the art described above, the object of the invention is to reduce or avoid the disadvantages mentioned, in particular to provide a locking mechanism with a lightweight, cost-effective and robust possibility for setting and / or readjustment.
Nach der Erfindung wird diese Aufgabe gelöst durch einen Riegelmechanismus nach Anspruch 1, also durch einen Riegelmechanismus für eine Tür, insbesondere für eine Fahrzeugtür, zum Beispiel eines Wohnmobils, eines Kfz-Anhängers, eines Wohnwagens oder eines Pferdetransporters, aufweisend zumindest ein Riegelelement zur Verriegelung der Tür in einer geschlossenen Stellung und eine Betätigungseinrichtung zum nutzerseitigen Überführen des Riegelelements aus einer Verriegelungsstellung in eine Entriegelungsstellung und/oder aus der Entriegelungsstellung in die Verriegelungsstellung, wobei das Riegelelement und die Betätigungseinrichtung mittels eines Zug-Druck-Elements mechanisch miteinander gekoppelt sind, wobei der Riegelmechanismus eine einstellbare Koppelmechanik aufweist zum einstellbaren Koppeln des Zug-Druck-Elements mit dem Riegelelement und/oder der Betätigungseinrichtung.According to the invention, this object is achieved by a locking mechanism according to claim 1, that is by a locking mechanism for a door, in particular for a vehicle door, for example a motorhome, a motor vehicle trailer, a caravan or a horse transporter, comprising at least one locking element for locking the Door in a closed position and an actuating device for user-side transfer of the locking element from a locking position to an unlocked position and / or from the unlocked position into the locking position, wherein the locking element and the actuating device are mechanically coupled to each other by means of a train-pressure element, wherein the locking mechanism an adjustable coupling mechanism comprises for adjustably coupling the train-pressure element with the locking element and / or the actuating device.
Eine Tür im Sinne der Erfindung umfasst neben Türen im engeren Sinne zum Betreten oder Verlassen eines von der Tür verschlossenen Raums außerdem im weiteren Sinne ähnliche zwischen einer Schließstellung und einer Offenstellung positionierbare Verschlusselemente, wie zum Beispiel Fenster, Klappen, Ladeklappen, Luken, etc.. Die Koppelmechanik ist vorzugsweise auch im montierten Zustand einfach zugänglich und ermöglicht in vorteilhafter Weise eine definierte, verlässliche und vor allem reproduzierbare Möglichkeit, um den Riegelmechanismus bei dessen Montage einzustellen sowie im Falle von Verschleiß ebenso nachzujustieren. Damit entfällt die Notwenigkeit, über manuelles Verbiegen des Zugstabs einstellen zu müssen, so dass dieser nicht infolge von Umformung geschwächt wird und außerdem keine Fehlausrichtungen oder Verkantungen in den Mechanismus eingebracht werden. Ein besonderer Vorteil ist, dass auch verdeckte und im Türinneren verlegte Riegelmechanismen ein- bzw. nachgestellt werden können.In addition to doors in the strict sense, a door in the narrower sense for entering or leaving a room closed by the door also has similar closure elements positionable between a closed position and an open position, such as windows, flaps, tailboards, hatches, etc. The coupling mechanism is preferably easily accessible even in the assembled state and advantageously allows a defined, reliable and above all reproducible way to adjust the locking mechanism during its assembly and readjust in case of wear as well. This eliminates the need to adjust by manually bending the tie rod so that it is not weakened as a result of deformation and also no misalignments or tilting are introduced into the mechanism. A particular advantage is that also hidden and moved inside the door latch mechanisms can be switched on or after.

Der Riegelmechanismus kann insbesondere zwei oder mehr mit der Betätigungseinrichtung wirkverbundene Riegeleinheiten aufweisen, die voneinander und von der Betätigungseinrichtung beabstandet an unterschiedlichen Positionen an der Tür angeordnet sind, um derart für eine Verriegelung der Tür mit einem Türrahmen, einer Zarge oder einem Türschloss an unterschiedlichen Stellen zu sorgen. Jede Riegeleinheit umfasst jeweils zumindest ein Riegelelement.In particular, the latch mechanism may include two or more latch units operatively connected to the actuator spaced apart from one another and from the actuator at different positions on the door so as to lock the door to a door frame, frame, or door lock at different locations to care.

Sie kann außerdem ein zweites mit dem Riegelelement gekoppeltes Nockenelement aufweisen. Das erste Nockenelement bzw. das zweite Nockenelement können mit dem Zug-Druck-Element bzw. dem Riegelelement in einer Mehrzahl unterschiedlicher Relativstellungen koppelbar sein. Bei dieser Ausführungsform wird die Einstellbarkeit des Riegelmechanismus durch eine Relativpositionierung des jeweiligen Nockenelements zu dem damit gekoppelten Teil des Mechanismus, d.h. dem Zug-Druck-Element bzw. dem Riegelelement, bewirkt. In einer bevorzugten Ausführungsform sind das erste Nockenelement und das zweite Nockenelement miteinander in einer Mehrzahl unterschiedlicher Relativstellungen zueinander koppelbar. Bei dieser Ausführungsform wird die Einstellbarkeit des Riegelmechanismus durch eine Relativpositionierung der beiden Nockenelemente zueinander bewirkt. Das Zug-Druck-Element ist vorzugsweise ein Stab, insbesondere ein Metallstab. Es ist im Sinne der Erfindung geeignet und bestimmt, Zugkräfte und/oder Druckkräfte zwischen der Betätigungseinheit und der jeweiligen Riegeleinheit und deren Riegelelement zu übertragen. Im Falle eines vorgespannten Schnappriegels mit Einlaufschräge muss es nur Kräfte in eine Richtung übertragen können.An embodiment of the invention is characterized in that the coupling mechanism has a first coupled to the train-pressure element cam member. It may also include a second cam member coupled to the latch member. The first cam element or the second cam element can with the train-pressure element or the locking element in a plurality of different relative positions can be coupled. In this embodiment, the adjustability of the locking mechanism is effected by a relative positioning of the respective cam member to the part of the mechanism coupled thereto, ie the tension-pressure element or the locking element. In a preferred embodiment, the first cam element and the second cam element can be coupled to each other in a plurality of different relative positions. In this embodiment, the adjustability of the locking mechanism is effected by a relative positioning of the two cam elements to each other. The tension-pressure element is preferably a rod, in particular a metal rod. It is suitable for the purposes of the invention and determines to transmit tensile forces and / or pressure forces between the actuator unit and the respective locking unit and its locking element. In the case of a preloaded latch with inlet slope, it only needs to be able to transmit forces in one direction.
Die Koppelmechanik kann nach einer Ausführungsform eine Koppelgeometrie aufweisen. Unter einer Koppelgeometrie in diesem Sinne ist ein Teil oder Abschnitt der Koppelmechanik zu verstehen, der mit entsprechend ausgebildeten Gegenkonturen auf Seiten des Zug-Druck-Elements bzw. des Riegelelements in Eingriff steht und in unterschiedlichen Funktionsstellungen / Eingriffsstellungen zur Gegenkontur positioniert werden kann. Eine solche Koppelgeometrie kann insbesondere in Form einer Verzahnung oder eines Mehrkants ausgebildet sein oder solches aufweisen. Über die Koppelgeometrie können insbesondere das erste Nockenelement und das zweite Nockenelement miteinander koppelbar sein.The coupling mechanism can according to one embodiment have a coupling geometry. Under a coupling geometry in this sense, a part or portion of the coupling mechanism is to be understood, which is in engagement with corresponding counter-contours on the side of the train-pressure element or the locking element and can be positioned in different functional positions / engagement positions to the mating contour. Such a coupling geometry can be designed in particular in the form of a toothing or a polygon or have such. In particular, the first cam element and the second cam element can be coupled to each other via the coupling geometry.
Eine Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Koppelmechanik einen Drehzapfen aufweist. Dieser kann einerseits rotationsfest mit einem der Nockenelemente und andererseits über die Koppelgeometrie mit dem anderen Nockenelement gekoppelt sein. Der Drehzapfen kann in einer Ausführungsform, in der das erste Nockenelement und das zweite Nockenelement auf einander gegenüberliegenden Seiten des Riegelelements angeordnet sind, das Riegelelement durchgreifen. Derart sind die erfindungsgemäße Riegelmechanik und insbesondere die Koppelmechanik einfach zu montieren und zu warten. Eine besonders montagefreundliche Möglichkeit besteht darin, dass der Drehzapfen eine mit einem Innengewinde versehene Öffnung aufweist und mit einer eines der Nockenelemente durchgreifenden Schraube an diesem lagefixiert ist.An embodiment of the invention is characterized in that the coupling mechanism has a pivot. This can on the one hand be rotationally fixed with one of the cam elements and on the other hand coupled via the coupling geometry with the other cam element. The pivot may in one embodiment, in which the first cam member and the second cam member on opposite sides of the locking element are arranged, pass through the locking element. In this way, the locking mechanism according to the invention and in particular the coupling mechanism are easy to assemble and to maintain. A particularly easy to install option is that the pivot has an opening provided with an internal thread and is fixed in position with a screw that passes through one of the cam elements.
Die Riegeleinheit des erfindungsgemäßen Riegelmechanismaus kann insbesondere eine Grundplatte mit einer Linearführung zur linearpositionierbaren Führung des Riegelelements aufweisen. Alternativ oder zusätzlich kann die Grundplatte mit einer Lagerstruktur zur drehpositionierbaren Lagerung zumindest eines der Koppelelemente und/oder des Drehzapfens versehen sein. Die Grundplatte ist vorzugsweise als Spritzgussbauteil aus Kunststoff ausgebildet, was im Hinblick auf Kosten und Gewicht vorteilhaft ist.The locking unit of the locking mechanism according to the invention can in particular have a base plate with a linear guide for linearly positionable guidance of the locking element. Alternatively or additionally, the base plate may be provided with a bearing structure for rotatably mounting at least one of the coupling elements and / or the pivot pin. The base plate is preferably formed as an injection molded plastic part, which is advantageous in terms of cost and weight.
Es ist besonders vorteilhaft, wenn das zweite Nockenelement eine mit dem Riegelelement in Eingriff stehende exzentrische Mitnahme aufweist. Alternativ oder zusätzlich kann das erste Nockenelement eine mit dem Zug-Druck-Element in Eingriff stehende exzentrische Mitnahme aufweisen. Über solche exzentrische Mitnahmen kann eine Linearverschiebung des Zug-Druck-Elements besonders einfach in eine Drehbewegung des ersten Nockenelements und eine Drehbewegung des zweiten Nockenelements besonders einfach in eine Linearverschiebung des Riegelelements umgewandelt werden.It is particularly advantageous if the second cam element has an eccentric driving engagement with the locking element. Alternatively or additionally, the first cam element may have an eccentric driving engagement with the tension-pressure element. About such eccentric driving a linear displacement of the train-pressure element can be particularly easily converted into a rotational movement of the first cam member and a rotational movement of the second cam member in a linear displacement of the locking element.
Es sei ausdrücklich darauf hingewiesen, dass die Erfindung sowohl mit Schnappverriegelungen genutzt werden kann, bei denen eine Betätigung des Riegelelements mittels der Betätigungseinheit nur in eine Richtung zu erfolgen hat, als auch mit solchen Verriegelungssystemen, bei denen das Riegelelement nicht als Schnapper ausgebildet ist, sondern dessen Betätigung in beide Richtungen zu erfolgen hat.It should be expressly understood that the invention can be used both with snap locks, in which an actuation of the locking element by means of the actuating unit has to be made only in one direction, as well as with such locking systems in which the locking element is not designed as a snapper, but whose operation has to be done in both directions.
