Description
Die Erfindung bezieht sich auf einen Türfeststeller für Kraftwagentüren, bestehend aus einer am einen Scharnierflügel gehalterten Drehstabfeder mit einem die Scharnierhöhe überragenden, parallel zur Scharnierachse gerichteten Belastungsarm und am anderen Scharnierflügel im Abstand zur Scharnierachse drehbar verlagerten Widerlagerrollen, die im Zusammenwirken mit dem Belastungsarm der Drehstabfeder wenigstens für eine Öffnungsstellung der Türe eine Verrastung bilden.The invention relates to a door lock for motor vehicle doors, consisting from a torsion bar spring held on a hinge wing with one the hinge height outstanding load arm parallel to the hinge axis and rotatably on the other hinge wing at a distance from the hinge axis Abutment rollers that interact with the load arm of the torsion bar form a catch at least for an open position of the door.
Bei einem bekannten, mit einem Türscharnier baulich vereinigten Türfeststeller der
vorgenannten Bauart, wie er beispielsweise aus der italienischen Patentschrift
728110 bekannt ist, sind die umfangsverzahnten Widerlagerrollen in einem mehr
oder minder beträchtlichen, jedenfalls in einem ihrer eigenen Durchmesser übersteigenden
Abstand voneinander angeordnet und gelangt der Belastungsarm der
Drehstabfeder beim Öffnen der Tür in der Nähe der ersten zu verrastenden Türöffnungsstellung
zunächst mit der ersten der beiden Widerlagerrollen in Eingriff
und wird von dieser um einen gewissen Betrag ausgelenkt, wodurch der Schwung
der in der Öffnungsbewegung befindlichen Tür abgebremst wird, bis der Belastungsarm
der Drehstabfeder beim weiteren Öffnen der Türe schließlich nach einer
Teilumdrehung der ersten Widerlagerrolle mit der zweiten Widerlagerrolle in Eingriff
gelangt und zwischen den beiden Widerlagerrollen festgehalten wird. Aus der
beabstandet hintereinanderliegenden Anordnung der Widerlagerrollen ergibt sich
hierbei ein erhebliches Spiel zwischen dem mit jeweils nur einer der beiden Widerlagerrollen
im unmittelbaren Eingriff stehenden Belastungsarm der Drehstabfeder
und der folgenden Widerlagerrolle, woraus notwendigerweise eine gewisse Bewegungsfreiheit
für die an sich in der ausgewählten Öffnungsstellung zu verrastende
Fahrzeugtür entsteht. Darüberhinaus besteht bei der bekannten Anordnung umfangsverzahnter
Widerlagerrollen die Möglichkeit, daß der Belastungsarm der
Drehstabfeder beim Auftreffen auf die zweite Widerlagerrolle auf einen Zahn
derselben auftrifft und somit nicht exakt verrastet, was naturgemäß zur Folge hat,
daß die Fahrzeugtür aus der eigentlich zu verrastenden Öffnungslage wieder um
einen gewissen Winkelbetrag ausläuft, sei es in Öffnungs- oder sei es in Schließrichtung.
Die Möglichkeit, daß der Belastungsarm der Drehstabfeder insbesondere
beim Auflaufen auf die zweite Widerlagerrolle auf einen Zahn trifft ist auch bei der
in der Figur 5 dieser Druckschrift gezeigten Ausführungsform mit in einem verhältnismäßig
kurzen Abstand voneinander gelagerten Widerlagerrollen noch gegeben,
so daß auch eine solche Anordnung die unerwünschte Pendelbewegung der Türe im
Bereich ihrer zu verrastenden Öffnungslage nicht auszuschließen vermag.
Pendelbewegungen der Tür um ihre eigentlich zu verrastende Öffnungslage sind
ganz generell unerwünscht, da sie eine Beschädigung der Türe, beispielsweise
durch Anschlagen an die Garagenwand oder beim Parken unter beengten räumlichen
Verhältnissen auf Parkplätzen zur Folge haben können.
Diese Nachteile der ersten bekannten Bauart eines mit einem Türscharnier baulich
vereinigten Türfeststellers der eingangs bezeichneten Bauart sind bei einer weiteren
aus der DE-PS 32 29 766 bekannten Bauart eines solchen Türfeststellers zwar
im Wesentlichen vermieden, jedoch haftet beiden bekannten Bauarten von mit
einem Türscharnier baulich vereinigten Türfeststellern zudem noch der Nachteil
an, daß die Anzahl der möglichen Raststellungen der Türe auf maximal zwei begrentz
ist.In a known door retainer of the aforementioned type, structurally combined with a door hinge, as is known, for example, from Italian patent specification 728110, the circumferentially toothed abutment rollers are arranged at a more or less considerable distance from one another, in any case exceeding their own diameter, and the load arm arrives When the door is opened near the first door opening position to be locked, the torsion bar spring first engages with the first of the two abutment rollers and is deflected by this by a certain amount, as a result of which the swing of the door in the opening movement is braked until the load arm of the torsion bar spring when the door is opened further, after a partial rotation of the first abutment roller, it finally comes into engagement with the second abutment roller and is held between the two abutment rollers. The spaced-apart arrangement of the abutment rollers results in considerable play between the load arm of the torsion bar spring, which is in direct engagement with only one of the two abutment rollers, and the following abutment roller, which necessarily means a certain freedom of movement for the vehicle door, which is to be locked in the selected open position arises. In addition, there is the possibility in the known arrangement of circumferentially toothed abutment rollers that the load arm of the torsion bar spring strikes a tooth of the same when it strikes the second abutment roller and thus does not lock exactly, which naturally has the consequence that the vehicle door again moves out of the opening position that is actually to be locked a certain angular amount runs out, be it in the opening or in the closing direction. The possibility that the load arm of the torsion bar spring hits a tooth, in particular when it strikes the second abutment roller, is also given in the embodiment shown in FIG. 5 of this document with abutment rollers mounted at a relatively short distance from one another, so that such an arrangement also undesirable pendulum movement of the door in the area of its opening position to be locked cannot rule out. Pendulum movements of the door around its opening position which is actually to be locked are generally undesirable since they can damage the door, for example by striking the garage wall or when parking in confined spaces in parking lots.
These disadvantages of the first known type of door lock structurally combined with a door hinge of the type described at the outset are essentially avoided in a further type of such door lock known from DE-PS 32 29 766, but both known types of structurally combined with a door hinge are liable Door locks also have the disadvantage that the number of possible locking positions of the door is limited to a maximum of two.
Der Erfindung liegt die Aufgabe zugrunde bei einem mit einem Türscharnier baulich vereinigten Türfeststeller der eingangs bezeichneten bauart für Kraftwagentüren eine Anordnung der Widerlagerrollen zu schaffen, welche eine die Zahl zwei übersteigende Mehrzahl über den zugelassenen Öffnungswinkel der Türe hin verteilt angeordneter Raststellungen der Türe gewährleistet und dabei zugleich unerwünschte Pendelbewegungen der Tür in den verschiedenen zu verrastenden Öffnungslagen mit Sicherheit ausschließt und welche darüber hinaus bei geringem Herstellungs-und Montageaufwand eine fehlerhafte Montage der Widerlagerrollen zwangsweise ausschließt. The invention has for its object in a structurally with a door hinge united door arrester of the type described at the beginning for motor vehicle doors to create an arrangement of abutment rollers, which one is the number two the majority over the approved opening angle of the door arranged locking positions of the door guaranteed and at the same time undesirable Pendulum movements of the door in the different opening positions to be locked excludes with certainty and which moreover with little Manufacturing and assembly costs a faulty assembly of the abutment rollers forcibly excludes.
Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, daß daß an einem am anderen Scharnierflüglel quer zur Scharnierachse ausgerichtet ausgebildeten Widerlagerträger wenigstens drei untereinander gleichförmige und mindestens über einen Teil ihrer Höhe hin gleiche im Wesentlichen herzförmige Querschnittsformen aufweisende Widerlagerrollen angeordnet sind, wobei die Lagerachsen der Widerlagerrollen in einem geringeren Abstand als dem größten Durchmesser ihrer Querschnittsform am Widerlagerträger des anderen Scharnierflügels angeordnet sind. Das erfindungsgemäße Abgehen von der bisher ausschließlich üblichen, auch unter Berücksichtigung einer Umfangsverzahnung mehr oder minder kreisrunden Umfangsform der Widerlagerrollen ermöglicht hand in hand mit einer einfachen Herstellungsweise der Widerlagerrollen, beispielsweise aus Abschnitten eines geeigneten Profilmaterials, nicht nur die Ausstattung des Türfeststellers mit einer Vielzahl von Raststellungen der Türe, sondern auch eine Sicherheit gegen ein unbeabsichtigt fehlerhaftes Montieren der Widerlagerrollen, indem sich bei der Montage der Widerlagerrollen deren gegenseitige Ausrichtung aus ihrer Querschnittsform zwangsweise ergibt. Zugleich ist im Betrieb des Türfeststellers auch jedwede gegenläufige Rotationsbewegung der Widerlagerrollen automatisch gesperrt.This object is essentially achieved in that one trained on the other hinge wing aligned transversely to the hinge axis Abutment support at least three mutually uniform and at least Essentially the same heart-shaped cross-sectional shapes over part of their height having abutment rollers are arranged, the bearing axes the abutment rollers at a smaller distance than the largest diameter their cross-sectional shape on the abutment support of the other hinge wing are arranged. The inventive departure from the previously exclusive usual, also taking into account a circumferential toothing more or The less circular circumferential shape of the abutment rollers enables hand in hand with a simple way of producing the abutment rollers, for example Sections of a suitable profile material, not just the equipment of the door arrester with a variety of locking positions of the door, but also one Security against inadvertently incorrect assembly of the abutment rollers, by mutually aligning the abutment rollers during assembly necessarily results from their cross-sectional shape. At the same time is in operation of the door arrester also any counter-rotating movement of the abutment rollers automatically locked.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen,
daß die Widerlagerrollen in einem zentralen Bereich eine kreisrunde Querschnittsform
und bezüglich dieser einander gegenüberliegend je eine radial gerichtete
Ausladung aufweisen, deren eine mit einer Rastausnehmung versehen ist und
deren andere glattflächig keilformig ausgebildet ist. Dabei ist im Einzelnen zweckmäßigerweise
weiterhin vorgesehen, daß die beiden radialen Ausladungen jeder der
Widerlagerrollen zueinander symetrisch ausgebildet sind und die Rastausnehmung
in der einen radialen Ausladung einen der Querschnittsform des Belastungsarmes
der Drehstabfeder einsprechenden Konturverlauf aufweist. Zwar wird der Belastungsarm
der Drehstabfeder im Allgemeinen eine kreisrunde Querschnittsform
besitzen, jedoch könnte in besonderen Fällen auch eine von der Kreisform abweichende,
beispielsweise quadratische, Querschnittsform des Belastungsarmes der
Drehstabfeder vorgesehen werden.
In der bevorzugten Ausführungsform ist jedoch vorgesehen, daß der Belastungsarm
der Drehstabfeder einen kreisrunden Profilquerschnitt besitzt und sich die Rastausnehmungen
in den radialen Ausladungen zweier benachbarter und gegeneinander
verschwenkter Widerlagerrollen einander zu einer Halbkreisform ergänzen.
Dies hat vorteilhafterweise eine glatte lückenlose und ruckfreie Übergabe des Belastungsarmes
der Drehstabfeder von einer zur nächstfolgenden Widerlagerrolle zur
Folge, d.h. der Belastungsarm der Drehstabfeder gleitet im Verlauf der Türbewegung
ohne jedwede Störung aus der Rastausnehmung der einen in die Rastausnehmung
der anderen Widerlagerrolle, so daß sich ein aboslut kontinuierlicher Übergang
und zugleich auch ein geräuschfreier Gang des Türfeststellers ergibt.According to a particularly preferred embodiment of the invention, it is provided that the abutment rollers have a circular cross-sectional shape in a central region and opposite each other a radially directed projection, one of which is provided with a latching recess and the other of which is wedge-shaped with a smooth surface. It is also expediently provided in detail that the two radial protrusions of each of the abutment rollers are symmetrical to one another and the latching recess in the one radial protrusion has a contour profile that corresponds to the cross-sectional shape of the loading arm of the torsion bar spring. Although the loading arm of the torsion bar spring will generally have a circular cross-sectional shape, in special cases a cross-sectional shape of the loading arm of the torsion bar spring that deviates from the circular shape, for example square, could also be provided.
In the preferred embodiment, however, it is provided that the loading arm of the torsion bar spring has a circular profile cross-section and the latching recesses in the radial projections of two adjacent and mutually pivoted abutment rollers complement one another to form a semicircular shape. This advantageously has a smooth, seamless and jerk-free transfer of the loading arm of the torsion bar spring from one to the next abutment roller, that is, the loading arm of the torsion bar slides in the course of the door movement without any interference from the latching recess of one into the latching recess of the other abutment roller, so that one Absolutely continuous transition and at the same time also results in a noiseless movement of the door arrester.
In weiterer Einzelausgestaltung der Widerlagerrollen kann dannferner vorgesehen sein, daß die beiden Flankenflächen der glattflächig keilförmig ausgebildeten radialen Ausladung jeder der Widerlagerrollen jeweils einen Winkel von 97° miteinander einschließen, so daß infolge des Umstandes, daß die glattflächig keilförmige Ausladung jeweils einen Schwenkendanschlag für die Widerlagerrolle bildet, der maximal mögliche Verschwenkwinkelbereich benachbarter Widerlagerrollen auf einen Winkelbetrag zwischen 90° und 100°, vorzugsweise einen Winkelbetrag von 97°, begrenzt ist.In a further individual configuration of the abutment rollers can then also be provided be that the two flank surfaces of the smooth wedge-shaped radial Discharge of each of the abutment rollers each with an angle of 97 ° include, so that due to the fact that the smooth wedge-shaped projection forms a swivel end stop for the abutment roller, the maximum possible swivel angle range of adjacent abutment rollers on one Angular amount between 90 ° and 100 °, preferably an angular amount of 97 °, is limited.
In der bevorzugten Gestaltungsform durch Längenabschnitte eines fortlaufenden Profilmaterials weisen die Widerlagerrollen über ihre gesamte Höhe hin durchgehend eine einheitliche Profilquerschnittsform auf und sind an Lagerachsen gelagert, die durch vermittels einer Umfangsrändel drehsicher in Bohrungsausnehmungen des Widerlagerträgers festgelegte Nietzapfen gebildet sind. Zudem kann vorgesehen sein, die Widerlagerrollen an den Lagerachsen gegen die Last einer bremsend wirkenden Federscheibe drehbar gelagert sind, um ein selbsttätiges Verdrehen bzw. Verschwenken auszuschließen und damit weitere Vorsorge für einen absolut ruhigen Gang des Türfeststellers zu treffen. In the preferred design, by length sections of a continuous The abutment rollers have profile material throughout their entire height a uniform profile cross-sectional shape and are mounted on bearing axles, by means of a circumferential knurl to prevent rotation in bore recesses of the abutment carrier are defined rivets. It can also be provided, the abutment rollers on the bearing axles against the load of a Braking spring washer are rotatably mounted to an automatic Exclude twisting or pivoting and thus further provision for to meet an absolutely quiet aisle of the door arrester.
Die Lagerachsen der Widerlagerrollen sind dabei zweckmäßigerweise am Widerlagerträger des anderen Scharnierflügels entlang einer zur Scharnierachse konzentrisch verlaufenden Bogenlinie angeordnet.The bearing axes of the abutment rollers are expediently on the abutment carrier the other hinge wing along one concentric to the hinge axis arranged curved line.
In weiterer Ausgestaltung einer bevorzugten Einzelausgestaltung eines mit einem Drehstab türfeststeller der vorstehend aufgezeigten Gestaltungsart ist weiterhin vorgesehen, daß der den Widerlagerträger beinhaltende Scharnierflügel durch einen gefalteten Blechmaterialzuschnitt gebildet ist und daß am Widerlagerträger eine einen starren Öffnungsendanschlag für die Türe bildende Nase ausgebildet ist.In a further embodiment of a preferred individual embodiment of one with one Torsion bar door arrester of the design shown above is still provided that the hinge wing containing the abutment carrier through a folded sheet material blank is formed and that on the abutment support a rigid opening end stop for the door is formed.

Das in der Zeichnung dargestellte Kraftwagentürscharnier besteht aus einer ersten
am einen, in der Zeichnung nicht im einzelnen dargestellten Türanordnungsteil
angeschlagenen umgreifenden Scharnierflügel 1 und einem am anderen, in der
Zeichnung gleichfalls nicht dargestellten Türanordnungsteil angeschlagenen zweiten,
eingreifenden Scharnierflügel 2 sowie einem Scharnierstift 3, über welchen
beide Scharnierflügel 1 und 2 gelenkig miteinander verbunden sind. Der eine umgreifende
Scharnierflügel 1 ist in an sich bekannter Weise aus einem gefalteten
Blechmaterialzuschnitt gebildet und weist einen etwa quer zu seiner Anschlagbasis
4 ausgerichteten Widerlagerträger 5 auf, an welchen über Lagerachsen 6 Widerlagerrollen
7 drehbar verlagert sind. Der andere eingreifende Scharnierflügel 2 weist
eine etwa L-förmige Querschnittsform auf und ist vermittels seines einen Profilschenkels
8 über den Scharnierstift 3 am Scharnierflügel 1 drehbar gelagert, während
sein anderer Profilschenkel 9 seiner Befestigung am Türanordnungsteil dient.
Am eingreifenden Scharnierflügel 2 ist in an sich bekannter Weise eine Drehstabfeder
10 über ihrem Schafteil derart gelagert, daß ihr Belastungsarm 11 den einen
Scharnierflügel 1 nach oben überragt. Der Belastungsarm 11 greift in eine Ausnehmung
12 des eingreifenden Scharnierflügels 2 ein und ist dadurch in seiner
Schwenkbarkeit um die Achse 13 des Schaftes der Drehstabfeder 10 begrenzt.
Bei dem in der Zeichnung dargestellten Ausführungsbeispiel sind die Widerlagerrollen
7 über ihre gesamte Höhe hin gleichförmig ausgebildet und weisen eine im
Wesentlichen herzförmige Querschnittsform auf. Im Einzelnen besitzen die Widerlagerrollen
7 in einem zentralen Bereich 14 eine kreisrunde Querschnittsform und
sind bezüglich dieser mit einander gegenüberliegend angeordneten und zueinander
symetrischen, radial gerichteten Ausladungen 15 und 16 ausgestattet, wobei die
radiale Ausladung 15 mit einer Rastausnehmung 17 versehen und die andere
radiale Ausladung 16 glattflächig keilformig ausgebildet ist. Die Rastausnehmung
17 in der einen radialen Ausladung 15 weist einen der kreisrunden Querschnittsform
des Belastungsarmes 11 der Drehstabfeder 10 einsprechenden Konturverlauf
auf. In der gezeigten Ausführungsform weisen die Rastausnemungen in der radialen
Ausladung 15 der Widerlagerrollen 7 jeweils einen viertelkreisförmigen Konturverlauf
auf, derart, daß sich die Rastausnehmungen 17 in den radialen Ausladungen
15 zweier benachbarter und gegeneinander verschwenkter Widerlagerrollen 7
einander zu einer Halbkreisform ergänzen.
Die beiden Flankenflächen 18 und 19 der glattflächig keilförmig ausgebildeten
radialen Ausladung 16 jeder der Widerlagerrollen 7 schließen jeweils einen Winkel
von 97° miteinander ein, so daß infolge des Umstandes, daß die glattflächig keilförmige
Ausladung 16 einen Schwenkendanschlag für die Widerlagerrolle 7 bildet,
der maximal mögliche Verschwenkwinkelbereich benachbarter Widerlagerrollen 7
auf einen Winkelbetrag von 97°, begrenzt ist. Die Widerlagerrollen 7 besitzen im
gezeigten Ausführungsbeispiel über ihre gesamte Höhe hin durchgehend eine einheitliche
Profilquerschnittsform auf und sind an Lagerachsen 6 gelagert, die durch
vermittels einer Umfangsrändel 20 drehsicher in Bohrungsausnehmungen des Widerlagerträgers
5 festgelegte Nietzapfen gebildet sind. Die Lagerachsen 6 der Widerlagerrollen
7 sind am Widerlagerträger 5 des anderen Scharnierflügels 2 entlang
einer zur Scharnierachse konzentrisch verlaufenden Bogenlinie angeordnet. Der
den Widerlagerträger 5 beinhaltende Scharnierflügel 2 ist durch einen gefalteten
Blechmaterialzuschnitt gebildet und weist im bereich seines freien Endes eine einen
starren Öffnungsendanschlag für die Türe bildende Nase 21 auf.The motor vehicle door hinge shown in the drawing consists of a first encompassing hinge wing 1 attached to one door arrangement part (not shown in detail in the drawing) and a second
