Description
Die Erfindung bezieht sich auf einen Torsionsband-Türfeststeller für Kraftwagentüren, bestehend aus einer vermittels eines Lagerbockes am einen Türanordnungsteil, Tür oder Türholm um eine zur Türscharnierachse wenigstens annähernd parallele Achse schwenkbar angelenkten Türhaltestange und einem von der Türhaltestange durchsetzten am anderen Türanordnungsteil angeschlagenen starren Haltergehäuse, wobei die Türhaltestange als Torsionsband ausgebildet und einerseits bezüglich ihrer Torsionsachse kippsicher in dem ihr Schwenklager bildenden Lagerbock abgestützt ist.The invention relates to a torsion band door lock for motor vehicle doors, consisting of a by means of a bearing block on a door arrangement part, door or door spar about an axis at least approximately parallel to the door hinge axis hinged door support rod and a rigid holder housing struck by the door support rod on the other door arrangement part, wherein the door support rod is designed as a torsion band and is supported on the one hand with respect to its torsion axis in the bearing block forming its pivot bearing.
Bei einer ersten z.B. aus DE-U-87 09 421 bekannten Bauart von Türfeststellern wird die die Brems-bzw. Haltekraft des Türfeststellers bewirkende Federlast durch im Haltergehäuse untergebrachte, die mit der Türhaltestange zusammenwirkenden Bremskörper unmittelbar beaufschlagende, Druckfedern bzw. elastische Zwischenkörper aufgebracht, was naturgemäß einen verhältnismäßig hohen Herstellungsaufwand für den Türfeststeller mit sich bringt, selbst dann wenn einer der beiden mit der Türhaltestange zusammenwirkenden Bremskörper feststehend angeordnet ist und lediglich der zweite mit der Türhaltestange zusammenwirkede Bremskörper mit der Last einer gegen das Haltergehäuse abgestützten Druckfeder bzw. elastischen Zwischenkörper beaufschlagt ist.
Bei einer abgewandelten Bauart solcher Türfeststeller ist wenigstens einer der mit der Türhaltstange zusammenwirkenden Bremskörper durch die Last einer gegen das Haltergehäuse abgestützten Drehstabfeder beaufschlagt. Dies ermöglicht ohne erhöhten Herstellungsaufwand die Aufbringung wesentlich größerer Brems-und Haltekräfte des Türfeststellers erfordert aber immer noch eine Vielzahl von Einzelteilen, die zu einem Türfeststeller zusammenzubauen sind, selbst dann wenn der federbelastete Bremskörper als Rolle ausgebildet und auf dem Belastungsarm einer C-oder S-förmigen Drehstabfeder gelagert ist.
Bei einer anderen aus der US-PS 2 715 746 bekannten Bauart von Türfeststellern ist einer aus einem einfachen und um seine Längsachse verdrillten Flachmaterialzuschnitt gebildeten Türhaltestange als Haltergehäuse ein mit einem Durchtrittsschlitz versehener Flachmaterialzuschnitt zugeordnet, derart, daß die Türhaltestange beim Durchgang durch den Schlitz des Flachmaterialzuschnittes um ihre Längsachse verformt wird und diese Verformungsarbeit als Bremskraft für die Türe genutzt wird. Bei einer solchen Ausbildung eines Türfeststellers kann weder ein einigermaßen geräuscharmer Gang der Türe noch kann in Ermangelung von Rastmarken eine sichere Fesstellung der Türe in bestimmten Öffnungslagen erreicht werden. Begründet durch den Umstand, daß im Laufe der Zeit unvermeidlich Korrosion auftritt, ist mit Sicherheit mit einer erheblichen Geräuschentwicklung beim Durchgang des verdrillten Bereiches der Türhaltestange durch den Durchtrittsschlitz des Haltergehäuses zu rechnen. Besonders nachteilig wirkt sich bei dem bekannten Türfeststeller aber die Tatsache aus, daß die um ihre Längsachse verdrillte Türhaltestange mit ihren Längsrändern allmählich Einlaufriefen in der den Brems-bzw. Haltekörper bildenden Schlitzausnehmung des das Haltergehäuse bildenden Flachmaterialzuschnittes erzeugt, was notwendigerweise zu einer Erweiterung der Schlitzausnehmung und damit einerseits zu einer ständig zunehmenden Verringerung der mittels dieses Türfeststellers aufbringbaren Bremskraft und andererseits zu einer Unbestimmtheit der Feststellagen der Türe führt.In a first type of door lock known from DE-U-87 09 421, for example, the braking or. Holding force of the door arrester spring load applied by pressure springs or elastic intermediate bodies accommodated in the holder housing and directly acting on the brake body interacting with the door retaining rod, which naturally entails a relatively high production outlay for the door arrester, even if one of the two brake bodies interacting with the door retaining rod is fixed and only the second brake body cooperating with the door support rod is subjected to the load of a compression spring or elastic intermediate body supported against the holder housing.
In a modified type of such door arrester, at least one of the brake bodies interacting with the door holding rod is acted upon by the load of a torsion bar spring supported against the holder housing. This enables without Increased manufacturing costs, the application of significantly greater braking and holding forces of the door arrester still requires a large number of individual parts which are to be assembled into a door arrester, even if the spring-loaded brake body is designed as a roller and is mounted on the loading arm of a C-shaped or S-shaped torsion bar spring is.
In another known type of door lock from US Pat. No. 2,715,746, a door holding rod formed from a simple flat material blank twisted about its longitudinal axis is assigned as a holder housing to a flat material blank provided with a passage slot, such that the door holding rod is passed through the slot of the flat material blank is deformed about its longitudinal axis and this deformation work is used as a braking force for the door. With such a design of a door arrester, the door can be walked in a reasonably quiet manner, and in the absence of locking marks, the door can be securely locked in certain opening positions. Due to the fact that corrosion inevitably occurs over time, a considerable amount of noise can certainly be expected when the twisted area of the door holding rod passes through the through slot of the holder housing. A particularly disadvantageous effect in the known door arrester is the fact that the door support rod twisted about its longitudinal axis gradually has its longitudinal edges with inlet grooves in the brake or. Slit recess forming the holding body of the flat material blank forming the holder housing is produced, which necessarily leads to an expansion of the slit recess and thus, on the one hand, to a constantly increasing reduction in means of the latter Door brake applied braking force and on the other hand leads to an uncertainty in the locking of the door.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde einen Türfeststeller der eingangs genannten Bauart dahingehend zu verbessern, daß er zum einen die Vorteile eines kleinbauend auszubildenden Türfeststellers der erstgenannten Bauart und zum anderen den Vorteil einer hohen Brems-und Haltekraft, wie sie für mit einer Drehstabfeder ausgestattete Türfeststeller charakteristisch ist, in sich vereinigt und dabei bei mindestens gleicher Wartungsfreiheit und Dauerstandzeit gegenüber beiden bekannten Bauarten mit einem wesentlich geringeren Aufwand herstellbar ist.Based on this prior art, the invention has for its object to improve a door arrester of the type mentioned in such a way that it has the advantages of a door arrester of the first-mentioned type to be designed in a compact manner and the advantage of a high braking and holding force, as is the case for Door lock equipped with a torsion bar spring is characteristic, is self-contained and can be produced with significantly less effort compared to both known types with at least the same maintenance freedom and long service life.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Türhaltestange aus einem einfachen oder gefalteten Flachmaterialzuschnitt besteht und mit quer zu ihrer Bewegungsebene gerichteten, wenigstens von ihrer Längsmitte ausgehend zu ihrem einen Längsrand hin ansteigend ausgebildeten Bremsrampen und zwischen diesen eingeschlossenen Rastmarken versehen ist und daß die Türhaltestange zugleich im Haltergehäuse zwischen zwei unnachgiebig gelagerten Bremskörpern hindurchgeführt ist, wobei die Bremskörper durch Walzen oder Nadeln aus einem verschleißfesten Material, insbesondere Stahl, gebildet und drehbar in dem starren Haltergehäuse gelagert sind.
Die Verwendung einer mit wenigstens von ihrer Längsmitte ausgehenden, quer zu ihrer Bewegungsebene gerichteten Bremsrampen und zwischen diesen eingeschlossenen Rastmarken versehenen Türhaltestange als Torsionsband ermöglicht eine optimal einfache Bauweise des Türfeststellers, da die aus einem Flachmaterialzuschnitt gebildete Türhaltestange um oder parallel zu ihrer Längsachse tordierbar gestaltet ist. Dadurch wird trotz der kleinbauenden und nur eine geringe Anzahl von Einzelteilen umfassenden Ausbildung des Haltergehäuses eine sehr hohe Brems-bzw. Haltekraft des Türfeststellers erreicht. Die Ausbildung der Bremskörper als Walzen oder Nadeln aus einem verschleißfesten Material ermöglicht darüberhinaus bei einfachster Gestaltung der Lagerung der Bremskörper auch noch einen geräuschfreien oder wenigstens sehr geräuscharmen Gang des Türfeststellers, was nicht zuletzt daraus resultiert, daß weder das Haltergehäuse noch die darin gelagerten Bremskörper den Torsionswiderstand der Türhaltestange nachzugeben vermögen.
Im Einzelnen kann die Erfindung in einer Vielzahl von Ausgestaltungsformen verwirklicht werden, wobei eine besondere Verwirklichungsform darin gesehen wird, daß die Türhaltestange mit von ihrem einen Längsrand ausgehend zu ihrem anderen Längsrand hin ansteigend ausgebildeten, Bremsrampen und sowie von diesen eingeschlossene Rastmarken bildenden Ausformungen versehen ist.This object is achieved in that the door support rod consists of a simple or folded flat material blank and is provided with brake ramps designed transversely to its plane of movement, at least starting from its longitudinal center starting at its longitudinal edge and rising between them, and that the door support rod is at the same time is guided in the holder housing between two rigidly mounted brake bodies, the brake bodies being formed by rollers or needles made of a wear-resistant material, in particular steel, and being rotatably mounted in the rigid holder housing.
The use of a door holding rod with at least from its longitudinal center, transversely to its plane of movement and braking latches provided between these locking marks, as a torsion band, enables an optimally simple construction of the door arrester, since that is a flat material blank formed door support rod is designed to be twistable around or parallel to its longitudinal axis. As a result, despite the small-sized construction of the holder housing and comprising only a small number of individual parts, very high braking or Holding force of the door arrester reached. The design of the brake body as rollers or needles made of a wear-resistant material also allows for a silent or at least very quiet movement of the door arrester with the simplest design of the storage of the brake body, which not least results from the fact that neither the holder housing nor the brake body stored therein has the torsional resistance the door support bar can yield.
In detail, the invention can be implemented in a variety of configurations, a particular embodiment being seen in the fact that the door holding rod is provided with ramps designed to rise from its one longitudinal edge to its other longitudinal edge, and also with moldings forming locking marks enclosed by these.
Unabhängig von der übrigen Ausgestaltung der die Torsionsband bildenden Türhaltestange ist im Interesse einer möglichsten Laufruhe des Türfeststellers zweckmäßigerweise weiter vorgesehen, daß die aus einem Flachmaterialzuschnitt bestehende Türhaltestange an wenigstens einem ihrer Längsränder mit einer gegenüber ihrer Bewegungsebene einseitig vorkragenden Randwulst versehen ist. Es versteht sich dabei von selbst, daß bei einer Anordnung einer Längswulst auch am anderen Längsrand der Türhaltestange die beiden Längswülste jeweils entgegengesetzt zueinander gerichtet sind, d.h. daß bezogen auf die Breite der Türhaltestange die an deren einer Längsseite angeordnete Längswulst nach unten und die an deren anderer Längsseite angeordnete Längswulst nach oben zeigt.Regardless of the rest of the design of the door support bar forming the torsion band, in the interest of the smoothest possible running of the door arrester, it is furthermore expediently provided that the door support bar, which consists of a flat material blank, is provided on at least one of its longitudinal edges with an edge bead projecting on one side with respect to its plane of movement. It goes without saying that with an arrangement of a longitudinal bead on the other longitudinal edge of the door holding rod, the two longitudinal beads are each directed opposite to each other, i.e. that, based on the width of the door holding rod, the longitudinal bead arranged on one longitudinal side points downward and the longitudinal bead arranged on the other longitudinal side points upward.
Hinsichtlich der Ausbildung des die Türhaltestange mit dem einen Türanordnungsteil verbindenden Schwenklagers ist nach einer ersten Verwirklichungsform vorgesehen, daß die aus einem Flachmaterialzuschnitt gebildete Türhaltestange mit ihrem ein Anlenkauge aufweisenden Ende derart zwischen den beiden Armen eines zweiarmigen Lagerbockes aufgenommen ist, daß das aus der Torsionsbelastung der Türhaltestange resultierende Moment unmittelbar gegen die Arme des Lagerbockes abgestützt ist.
Dabei kann die Türhaltestange zwecks weitgehender Verringerung metallischer Reibung, gegebenenfalls unter Auskleidung des Innenumfanges ihres Anlenkauges mit einem Ring aus Lagermaterial an dem Nietbolzen gelagert sein.With regard to the design of the pivot bearing connecting the door holding rod to the one door arrangement part, it is provided according to a first embodiment that the door holding rod formed from a flat material blank with its end having a pivot eye is received between the two arms of a two-armed bearing block in such a way that the torque resulting from the torsional load on the door holding rod is supported directly against the arms of the bearing block.
The door holding rod can be mounted on the rivet bolt with a ring of bearing material for the purpose of largely reducing metallic friction, if necessary by lining the inner circumference of its articulation eye.
Anstelle einer unmittelbaren und insbesondere spielfrei zu gestaltenden Abstützung des freien Endes der Türhaltestange an den Seitenwangen der Arme des Lagerbockes kann gemäß einer anderen Verwirklichungsform aber auch vorgesehen sein, daß die Türhaltestange über eine Anlenkaugenbohrung mittels formschlüssigen Eingriffes kippsicher mit einer massiven Lagerhülse verbunden und die Lagerhülse ihrerseits vermittels eines sie durchsetzenden, insbsondere als Nietbolzen ausgebildeten, Lagerstiftes an dem zweiarmigen Lagerbock gelagert ist. An der Lagerbuchse kann die Türhaltestange vermittels einer Umfangsnut in der Lagerhülse und außermittig zu deren Länge, z.B. in deren unterem Drittel angeschlossen sein, so daß hinsichtlich der Ausgestaltung bzw. der Anpassung der Anlenkung der Türhaltestange eine gewisse Gestaltungsfreiheit gegeben ist.Instead of a direct and in particular play-free support of the free end of the door holding rod on the side cheeks of the arms of the bearing block, it can also be provided according to another form of implementation that the door holding rod is connected to a solid bearing sleeve by means of a positive engagement by means of positive engagement and the bearing sleeve in turn is mounted on the two-armed bearing block by means of a bearing pin which passes through it, in particular in the form of a rivet bolt. At the bearing bush, the door holding rod can be made by means of a circumferential groove in the bearing sleeve and off-center to its length, e.g. be connected in the lower third, so that there is a certain amount of design freedom with regard to the design or adaptation of the articulation of the door support rod.
Einer weitere, insbesondere maschinell herstellbare Ausgestaltung der Schwenklagerung der Türhaltestange zeichnet sich dadurch aus, daß die die Türhaltestange am Lagerstift des zweiarmigen Lagerbockes lagernde bzw. abstützende Lagerhülse durch eine Stauchbuchse gebildet ist, wobei die Stauchbuchse einerseits über zwei Stauchbunde spielfrei an der Türhaltestange anliegt und andererseits über je einen Endbund an jedem der beiden Arme des Lagerbockes anliegt.A further, in particular mechanically producible, design of the pivot bearing of the door holding rod is characterized in that the bearing sleeve supporting or supporting the door holding rod on the bearing pin of the two-armed bearing block is formed by a compression bushing, the compression bushing, on the one hand, resting against the door support rod without play via two compression collars, and on the other hand over each end collar on each of the two arms of the bearing block.
Hinsichtlich der Ausbildung des Haltergehäuses ergibt sich eine mit einem geringstmöglichen Aufwand herstell- und montierbare Ausführungsform daraus, daß das Haltergehäuse durch einen mit Durchgangsbohrungen für Befestigungsschrauben versehenen Materialblock gebildet ist, wobei der das Haltergäuse bildende Materialblock vorteilhafterweise einteilig als Spritzgußteil, insbesondere aus einem Kunststoffmaterial, gebildet ist. In den Schmalseiten der die Durchgangsöffnung für die Türhaltestange bildenden Mitten-Öffnung des Materialblockes sind hierbei zweckmäßigerweise nach außen offene Nuten oder dergl. Ausnehmungen vorgesehen in die die Bremskörper bildenden Walzen eingesetzt und durch nachträgliches Verstemmen der Nutenränder festgelegt werden können.
Anstelle einer unmittelbaren Schraubbefestigung eines als einteiliger Materialblock ausgebildeten Haltergehäuses am zugehörigen Türanordnungsteil kann auch dessen Befestigung mittels eines Blechrahmens vorgesehen sein, wobei dann der Blechrahmen mit einem oberen Kranz die Randbereiche des Materialblockes übergreift und über untere seitlich auskragende Lappen und Schraubenbolzen oder dergl. am Türanordnungsteil befestigt ist.With regard to the design of the holder housing, one can produce and assemble it with the least possible effort Embodiment that the holder housing is formed by a block of material provided with through holes for fastening screws, the block of material forming the holder housing is advantageously formed in one piece as an injection molded part, in particular from a plastic material. In the narrow sides of the central opening of the material block forming the through-opening for the door retaining rod, grooves or the like which are open to the outside are expediently provided, into which the rollers forming the brake body can be inserted and fixed by subsequent caulking of the groove edges.
Instead of a direct screw fastening of a holder housing designed as a one-piece material block to the associated door arrangement part, its fastening can also be provided by means of a sheet metal frame, in which case the sheet metal frame with an upper rim overlaps the edge areas of the material block and is fastened to the door arrangement part via lower laterally projecting tabs and screw bolts or the like is.
Gleichfalls in Vollmaterialausbildung kann das Haltergehäuse aber auch zweiteilig gestaltet, insbesondere parallel zur Durchgangsebene der Türhaltestange geteilt sein, wobei dann die beiden Gehäuseteile gleichfalls aus Spritzgußteilen, insbesondere aus einem Kunststoffmaterial, bestehen können.Likewise in solid material design, the holder housing can also be designed in two parts, in particular divided parallel to the passage plane of the door holding rod, in which case the two housing parts can also consist of injection molded parts, in particular of a plastic material.
Eine abweichende Verwirklichungsform des Haltergehäuses besteht darin, daß das Haltergehäuse als zweiteiliges, aus einem flachen Topfteil und einem ebenen Deckelteil bestehendes Blechgehäuse ausgebildet ist.A different form of realization of the holder housing is that the holder housing is designed as a two-part sheet metal housing consisting of a flat pot part and a flat cover part.

Bei der in der Figur 8 dargestellten Ausführungsform eines die Türhaltestange 6 mit der Türe verbindenden Schwenklagers 1 ist die aus einem Flachmaterialzuschnitt gebildete Türhaltestange 6 mit ihrem ein Anlenkauge 25 aufweisenden Ende derart zwischen den beiden Armen 26 und 27 eines zweiarmigen Lagerbockes 1 aufgenommen, derart, daß das aus der Torsionsbelastung der Türhaltestange 6 resultierende Moment unmittelbar gegen die Arme 26 und 27 des Lagerbockes 1 abgestützt ist. Im übrigen ist die Türhaltestange 6 vermittels eines die beiden Arme 26 und 27 des Lagerbockes 1 durchgreifenden Nietbolzens gelagert.In the embodiment shown in FIG. 8 of a
Bei der in der Figur 9 dargestellten, gegenüber derjenigen nach Figur 8 abgewandelten Ausführungsform eines Schwenklagers 1 ist die Türhaltestange 6 zwecks weitgehender Verringerung metallischer Reibung im Schwenklager 1 unter Auskleidung des Innenumfanges ihres Anlenkauges 25 mit einem Ring 28 aus Lagermaterial an dem Nietbolzen 29 gelagert.In the embodiment of a
Bei der in der Figur 10 dargestellten Ausführungsform ist die Türhaltestange 6 über ihre Anlenkaugenbohrung 25 mittels formschlüssigen Eingriffes kippsicher mit einer massiven Lagerhülse 30 verbunden und die Lagerhülse 30 ihrerseits vermittels eines sie durchsetzenden, als Nietbolzen 29 ausgebildeten, Lagerstiftes an dem zweiarmigen Lagerbock 1 gelagert, wobei die Türhaltestange 6 in eine Umfangsnut der Lagerhülse 30 eingreift und insgesamt außermittig zu deren Länge, in deren unterem Drittel an die Lagerhülse 30 angeschlossen ist.In the embodiment shown in FIG. 10, the
Eine vorteilhaft maschinell herstellbare Ausgestaltung der Schwenklagerung 1 der Türhaltestange 6 ist in der Darstellung der Figur 11 gezeigt, wobei eine die Türhaltestange 6 an einem durch einen Nietbolzen 29 gebildeten Lagerstift des zweiarmigen Lagerbockes 1 lagernde bzw. abstützende Lagerhülse 31 durch eine Stauchbuchse gebildet ist und einerseits über zwei Stauchbunde 32,33 spielfrei an der Türhaltestange 6 anliegt und andererseits über je einen Endbund 34 bzw. 35 an jedem der beiden Arme 26 und 27 des Lagerbockes 1 anliegt.An advantageously mechanically producible configuration of the pivot bearing 1 of the
Aus der Darstellung der Figur 12 ist schließlich noch ersichtlich, daß die Türhaltestange entweder durch einen einteiligen und einlagigen oder aber einen zwar einteiligen aber doppellagig gefalteten Flachmaterialzuschnitt gebildet und je nach den sich aus der Einbaulage des Türfeststellers in der Fahrzeugkarosserie ergebenden Erfordernissen ein- oder beidseitig mit abgerundeten Randkanten versehen sein kann.
Insbesondere ist aus der Darstellung der Figur 12 noch eine besondere ausgestaltungsmöglichkeit der Türhaltestange 6 ersichtlich, dahingehend, daß sie im Interesse einer möglichsten Laufruhe des Türfeststellers an wenigstens einem ihrer Längsränder mit einer gegenüber ihrer Bewegungsebene einseitig vorkragenden Randwulst 36 versehen ist. Bei einer Anordnung je einer Längswulst 36 an beiden Längsrändern der Türhaltestange 6 sind die beiden Längswülste 36 jeweils entgegengesetzt zueinander angeordnet, d.h. daß bezogen auf die Breite der Türhaltestange 6 die an deren einer Längsseite angeordnete Längswulst 36 nach unten und die an deren anderer Längsseite angeordnete Längswulst 36 nach oben zeigt.Finally, from the illustration in FIG. 12, it can still be seen that the door holding rod is formed either by a one-piece and single-layer or a one-piece but double-layer folded flat material blank and, on one or both sides, depending on the requirements resulting from the installation position of the door arrester in the vehicle body rounded edges can be provided.
In particular, from the illustration in FIG. 12, a special design option of the
