Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Türhaltestange für solche Kraftwagentürfeststeller, bei denen eine aus einem Flachmaterialzuschnitt gebildete und am einen Türanordnungsteil, Tür oder Türsäule, um eine zur Türscharnierachse parallele Achse schwenkbar angelenkte Türhaltestange über quer zu ihrer Bewegungsebene vorspringende Rastrampen oder dergl. mit in einem am anderen Türanordnungsteil feststehend angeordneten Haltergehäuse untergebrachten Brems-oder Haltekörpern zusammenwirkt.The invention relates to a method for producing a door support rod for such motor vehicle door locks, in which a formed from a flat material blank and on a door arrangement part, door or door pillar, pivoted about an axis parallel to the door hinge axis, door support rod protruding transversely to its plane of movement or the like. interacts with brake or holding bodies accommodated in a holder housing which is fixedly arranged on the other door arrangement part.

Zur Verwendung in Verbindung mit Türfeststellern der vorgenannten Bauart ist eine Vielzahl von Gestaltungsformen von Türhaltestangen, insbesondere mehrteiligen oder aus einem gefalteten Flachmaterialzuschnitt gebildeten Türhalestangen bekannt. Insbesondere ist es aber auch bekannt, die Türhaltestange aus einem Flachmaterialzuschnitt zu bilden, wobei der Flachmaterialzuschnitt ein- oder beidseitig mit senkrecht zu seiner allegemeinen Ebene gerichteten, die Brems oder Bremsrampen bildenden Verformungen versehen wird.For use in connection with door stays of the aforementioned type, a large number of designs of door holding bars, in particular multi-part door bars or formed from a folded flat material blank, are known. In particular, however, it is also known to form the door holding rod from a flat material blank, the flat material blank being provided on one or both sides with deformations which form perpendicular to its general plane and form the braking or braking ramps.

Bei einer aus der FR-PS 1 143 995 bekannten Ausgestaltungsform ist dabei vorgesehen, daß ein im mittleren Bereich der Breite des die Türhaltestange bildenden Flachmaterialzuschnittes wenigstens teilweise freigeschnittener bereich des Flachmaterialzuschnittes nach der einen oder der anderen Seite soweit durchgestellt ist, daß sich die erforderliche Höhe der Rast-oder Bremsrampen ergibt, die im Falle der genannten Konstruktion wenigstens dem Betrag der Materialdicke des Flachmaterialzuschnittes entspricht. Diese bekannte Ausgestaltung der Türhaltestange ist aber mit dem Nachteil behaftet, daß die aus dem Flachmaterialzuschnitt freigeschnittenen und dessen Ebene gegenüber durchgebogenen Bereiche wenigstens im Bereich der größten Erhebung der Rast-oder Bremsrampen keine Abstützung gegen die angrenzenden Breiche der Türhaltestange haben und daher beim Durchgang zwischen den Bremskörpern des Haltergehäuses durch deren Anpresskraft federnd elastisch verformt werden und dadurch ihre eigentliche Kontur mehr oder weniger verlieren, so daß auch die Präzision, mit der die Tür abgebremst bzw. verrastet wird mehr oder minder verloren geht und die Tür vielmehr an einer nicht genau vorherbestimmbaren Stelle ihres Öffnungswinkels abgebremst bzw. festgehalten wird, was im Hinblick auf die meist beträtchliche Länge der Türen insbesondere zweitüriger Fahrzeuge durchaus zu Schwierigkeiten führen kann, beispielsweise weil in engen Garagen die Tür an der Garagenwand anschlägt.In one embodiment known from FR-PS 1 143 995, it is provided that an area of the flat material blank that is at least partially cut free in the central region of the width of the flat material blank forming the door holding rod is pushed through to one side or the other to such an extent that the required height the locking or braking ramps results, which in the case of the construction mentioned corresponds at least to the amount of the material thickness of the flat material blank. However, this known design of the door holding rod has the disadvantage that the cut out of the flat material blank and its plane compared to bent areas have no support against the adjacent areas of the door holding rod at least in the area of the largest elevation of the locking or braking ramps and therefore during the passage between the Brake bodies of the holder housing are resiliently deformed by their contact pressure and thereby lose their actual contour more or less, so that the precision with which the door is braked or locked is more or less lost and the door is rather braked or held at a point in its opening angle that cannot be precisely determined, which is what With regard to the mostly substantial length of the doors, in particular two-door vehicles, can certainly lead to difficulties, for example because the door strikes the garage wall in narrow garages.

Bei einer anderen, beispielsweise aus der DE-AS 1 459 126 bekannten Gestaltungsform einer Türhaltestange für Türfeststeller der eingangs beschriebenen Bauart sind die Rast-oder Bremsrampen der aus einem Flachmaterialzuschnitt geformten Türhaltestange durch entsprechendes einseitiges Prägen des Flachmaterialzuschnittes ausgeformt, wobei die Rast-bzw. Bremsrampen schnittfrei mit den angrenzenden Bereichen des die Türhaltestange bildenden Flachmaterialzuschnittes verbunden sind. Bei dieser Gestaltungsform können die der vorstehend beschriebenen Gestaltungsform anhaftenden Nachteile, insbesondere das unerwünschte Durchfedern der Rast-bzw. Bremsrampen zwar vermieden werden, jedoch nur dadurch, daß einerseits der zur Herstellung der Türhaltestange verwendete Flachmaterialzuschnitt eine erhebliche Materialdicke aufweist und daß andererseits die maximale Höhe der Rast-bzw. Bremsrampen der Türhaltestange deutlich kleiner ist als die Materialdicke des Ausgangs-Flachmaterialzuschnittes. Derartig geringe Höhen der Rast- oder Bremsrampen sind aber in den meisten Fällen nicht brauchbar, da sie eine hohe Anpresskraft der mit ihnen zusammenwirkenden Rast-oder Bremskörper und damit besonders bei schweren Fahrzeugtüren einerseits die Herstellung des Türfeststellers verteuern und andererseits einer großen Abnutzung unterliegen.In another, for example from DE-AS 1 459 126 known design of a door holding rod for door locks of the type described in the introduction, the locking or braking ramps of the door holding rod formed from a flat material blank are formed by correspondingly embossing the flat material blank on one side, the locking or. Brake ramps are cut-free connected to the adjacent areas of the flat material blank forming the door holding rod. With this design form, the disadvantages inherent in the design form described above, in particular the undesired deflection of the locking or Brake ramps are avoided, but only in that on the one hand the flat material blank used to produce the door retaining bar has a considerable material thickness and on the other hand that the maximum height of the latching or. Brake ramps of the door support rod is significantly smaller than the material thickness of the starting flat material blank. Such low heights of the latching or braking ramps are, however, not usable in most cases, since they make the manufacture of the door arrester more expensive, on the one hand, and make them heavily worn, on account of the high contact pressure of the latching or braking bodies interacting with them, and thus particularly in the case of heavy vehicle doors.

Ferner ist auch aus der EP-A-2175 eine Türhaltestange bekannt geworden, die für solche Kraftwagentürfeststeller bestimmt ist, bei denen eine aus einem Flachmaterialzuschnitt gebildete und am einen Türanordnungsteil, Tür oder Türsäule, um eine zur Scharnier- achse parallele Achse schwenkbar angelenkte Türhaltestange über quer zu ihrer Bewegungsebene vorspringende Rastrampen mit in einem am anderen Türanordnunsteil feststehend angeordneten Haltergehäuse untergebrachten Brems-oder Haltekörpern zusammenwirkt, wobei die sich über einen mittleren Bereich der Türhaltestange hin erstrekkenden Rast-oder Bremsrampen einseitig an einer aus einem ebenen Flachmaterialzuschnitt hergestellten Türhaltestange ausgeformt sind und eine wenigstens annähernd deren voller Materialstärke entsprechende maximale Höhe aufweisen. Die Rast-oder Bremsrampe ist bei dieser Türhaltestange gleichfalls durch Prägen in einem besonderen Arbeitsgang aus einem Flachmaterialzuschnitt herausgedrückt, was zunächst keine Sicherheit gegen ein federnd elastisches Verformen der Rast-oder Bremsrampen beim Durchgang der Türhaltetange durch das Haltergehäuse gewährleistet und ferner die Verwendung eines hinreichend dicken Ausgangsmaterials vorraussetzt.Furthermore, from EP-A-2175 a door support rod has become known which is intended for those motor vehicle door arresters in which a door support rod formed from a flat material blank and on one door arrangement part, door or door pillar is pivoted about an axis parallel to the hinge axis projecting ramps protruding transversely to their plane of movement with one another Bracket or holding bodies arranged in a stationary manner in the door arrangement part of the housing housing cooperates, the latching or braking ramps extending over a central region of the door holding rod being formed on one side on a door holding rod made of a flat flat material blank and having a maximum height that corresponds at least approximately to their full material thickness. The latching or braking ramp is also pressed out of a flat material blank by stamping in a special operation in this door holding bar, which initially does not guarantee any security against resiliently deforming the latching or braking ramps when the door holding bar passes through the holder housing and furthermore the use of a sufficiently thick one Starting material required.

Der Erfindung liegt daher die Aufgabe zugrunde ein Verfahren zur Herstellung einer mit Brems-oder Rastrampen versehenen Türhaltestange für einen Türfeststeller der eingangs genannten Bauart aus einem einteiligen Flachmaterialzuschnitt herkömmlicher Materialqualität aufzuzeigen, mittels dessen die Türhaltestange bei geringstem Aufwand einerseits mit, eine ausreichende, insbesondere wenigstens annähernd der Materialdicke eines Ausgangs-Flachmaterialzuschnittes entsprechende Höhe aufweisenden, Rast-bzw. Bremsrampen ausgestattet werden kann und andererseits eine ausreichende Festigkeit erhält, um eine ungewollte Verformung der Rast- bzw. Bremsrampen beim Durchgang der Türhaltestange durch das Haltergehäuse zu vermeiden.The invention is therefore based on the object of demonstrating a method for producing a door holding rod provided with braking ramps or locking ramps for a door arrester of the type mentioned at the beginning from a one-piece flat material blank of conventional material quality, by means of which the door holding rod, on the one hand, with a minimum of effort, a sufficient, in particular at least approximately height corresponding to the material thickness of a starting flat material blank, latching or. Brake ramps can be equipped and on the other hand receives sufficient strength to avoid an undesired deformation of the locking or braking ramps when the door holding rod passes through the holder housing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Türhaltestange im Wege des Fließpressens schnittfrei aus einem ebenen Flachmaterialzuschnitt geformt wird, wobei die Rast- oder Bremsrampen sich nur über einen mittleren Bereich der Breitseite der Türhaltestange hin erstreckendend und einseitig derart aus dem ebenen Flachmaterialzuschnitt herausgefomt werden, daß sie eine wenigstens annähernd der vollen Materialstärke des Ausgangsmaterials entsprechende maximale Höhe aufweisen.This object is achieved according to the invention in that the door holding rod is formed without cutting from a flat sheet material blank by extrusion, the locking or braking ramps extending only over a central region of the broad side of the door holding rod and being removed from the flat sheet material blank on one side in this way, that they have a maximum height corresponding at least approximately to the full material thickness of the starting material.

Das erfindungsgemäße Herstellungsverfahren führt zu einer als Fließpressteil gestalteten Türhaltestange und gewährleistet auf der einen Seite eine einfache Herstellbarkeit der Türhaltestange und auf der anderen Seite eine mit den umgebenden Flächenbereichen des das Ausgangsmaterial bildenden Flachmaterialzuschnittes zusammenhängende Ausbildung der Rast-oder Bremsrampen und damit gleichzeitig auch eine bleibende Abstützung derselben gegen die Basis der Türhaltestange, so daß auch bei einer wenigstens annähernd der vollen Materialdicke des Ausgangs-Flachmateriales entsprechenden größten Höhe der Rast-oder Bremsrampen ein Durchfedern derselben beim Durchgang durch das Haltergehäuse ausgeschlossen ist.The manufacturing method according to the invention leads to a door holding rod designed as an extruded part and ensures, on the one hand, that the door holding rod can be manufactured easily and, on the other hand, that the latching or braking ramps are formed with the surrounding surface areas of the flat material blank forming the starting material and, at the same time, also provides permanent support the same against the base of the door holding rod, so that even with a maximum height of the latching or braking ramps corresponding to at least approximately the full material thickness of the starting flat material, springing of the same is excluded when passing through the holder housing.

In einer Ausgestaltung des Verfahrens ergibt sich eine einfache aber wirkungsvolle Stabilisierung der Rast-bzw. Bremsrampen dadurch, daß die Übergänge zwischen dem unteren Bereich der ausgeformten Rast-oder Bremsrampen und den angrenzenden ebenen Bereichen des die Türhaltestange bildenden Flachmaterialzuschnittes sowohl oberseitig als auch unterseitig radienförmig ausgeformt werden. Eine besonders einfache und daher bevorzugte Ausführungsform des Verfahrens sieht daher vor, daß der Ausgangs- Flachmaterialzuschnitt zu einer im wesentlichen U-förmigen Profil-Querschnittsform verformt wird, wobei der Außenumfang des Profilquerschnittes im wesentlichen rechtwinkelige Begrenzungskanten erhält und der innenliegende Umfang des Prolfilquerschnittes wannenförmig mit im wesentlichen bogenförmigen Begrenzungskanten versehen wird.In one embodiment of the method, there is a simple but effective stabilization of the latching or. Braking ramps in that the transitions between the lower region of the formed latching or braking ramps and the adjoining flat regions of the flat material blank forming the door holding rod are shaped radially on both the top and the bottom. A particularly simple and therefore preferred embodiment of the method therefore provides that the starting flat material blank is deformed into an essentially U-shaped profile cross-sectional shape, the outer circumference of the profile cross section being given essentially rectangular boundary edges and the inner circumference of the profile section being trough-shaped essential arcuate boundary edges is provided.

Eine besonders wirkungsvolle Abstützung bzw. Stabilisierung der Rast-bzw.Bremsrampen kann in weiterer Ausgestaltung des Verfahrens dadurch erreicht werden, daß die Rast-oder Bremsrampen mit ihren Unterkanten linienförmig an den innenliegenden Oberkanten der ebenen Bereiche des die Türhaltestange bildenden Flachmaterialzuschnittes anliegend geformt und in Abständen über im wesentlichen quer zur Längserstreckung der Rast-oder Bremsrampen gerichteten Stegen versehen werden, die unter Ausformung innerenliegender Übergangsradien gestaltet werden und eine Abstützung der Rast-bzw. Bremsrampen gegen die ebenen Bereiche der Türhaltestange bilden.A particularly effective support or stabilization of the latching or braking ramps can be achieved in a further embodiment of the method in that the latching or braking ramps are shaped with their lower edges in line with the inner upper edges of the flat areas of the flat material blank forming the door holding rod and at intervals are provided via webs which are directed essentially transversely to the longitudinal extent of the latching or braking ramps, which are designed by forming internal transition radii and supporting the latching or. Form braking ramps against the flat areas of the door support bar.

Das für die Ausbildung der Stege erforderliche Material wird bei der Ausformung der Rast-bzw. Bremsrampen der Türhaltestange aus den Bereichen der linienförmigen Anlage der Rast-oder Bremsrampen an den ebenen Bereichen der Türhaltestange verdrängt.The material required for the formation of the webs is used in the formation of the locking or. Brake ramps of the door holding rod are displaced from the areas of the linear arrangement of the latching or braking ramps on the flat areas of the door holding bar.

Bei Türhaltestangen die aufgrund der Bauart oder der Anordnung des Türfeststellers in vertikaler Richtung ausgerichtet eingesetzt werden müßen ist in Vervollständigung des erfindungsgemäßen Verfahrens ferner vorgesehen, daß die Türhaltestange im Bereich ihres Anlenkendes gleichzeitig zu einem rechtwinkelig zu ihrer Durchgangsebene durch das Haltergehäuse abgewinkelten Anlenkauge verformt wird.In the case of door support rods which, due to the design or the arrangement of the door arrester, must be oriented in the vertical direction, in addition to the method according to the invention, it is also provided that the door support rod is deformed in the region of its articulation end at the same time as a pivot eye angled at right angles to its passage plane through the holder housing.

The rest or Brake ramps 1 and 2 are arranged in the longitudinal center of the flat material blank forming the door holding rod 3 and only occupy the central area thereof, such that on both sides of the locking or braking ramps 1 and 2 there are respectively flat adjacent and smooth surface areas 4 and 5 of the initial flat material blank . In the first embodiment, the shape of the locking or. Brake ramps 1 and 2 are designed in accordance with FIG. 2 in such a way that the locking or. Brake ramps 1 and 2 along their two long sides 6 and 7 remain connected to the smooth-surface areas 4 and 5 of the starting flat material blank via transitional bridges 8 and 9.

Hinsichtlich der sich über eine größere Länge der Türhaltestange 30 erstreckenden Bremsrampe 20 ist hier jedoch eine andere Gestaltungsform gezeigt, dahingehend, daß die Unterseite 21 der Bremsrampe 20 über kurze Abschnitte 22 hin lediglich linienförmig mit den angrenzenden glattflächigen Bereichen 40 und 50 verbunden ist, wobei die Übergänge 120 einen rechten Winkel bilden bzw. mit einem in der Zeichnung nicht darstellbar kleinen Radius ausgestattet sind. Beiderseits der Abschnitte 22 ist die Bremsrampe 20 über im wesentlichen quer zu ihrer Längserstreckung gerichtete Stege 23 mit den angrenzenden glattflächigen Bereichen 40 und 50 verbunden, wobei die Stege 23 zumindest innenseitig in einem Radius 110 bzw. 112 in die Innenflächen 130 und 140 des Ausgangs-Flachmaterialzuschnittes übergehen, derart daß das Innen-Querschnittsprofil eine abgerundete U-Form aufweist. An die Außenflächen 170 und 180 der glattflächigen Bereiche 40 und 50 schließen die zu diesen senkrecht gerichteten Seitenflächen der Bremsrampe 20 im rechten Winkel bzw. mit einem in der Zeichnung nicht darstellbar kleinen Radius an.
Bei den Ausführungsformen nach den Figuren 1,3 und 4 ist die Türhaltestange 3 bzw. 30 übereinstimmend mit einem senkrecht zu ihrer allgemeinen Ebene abgewinkelten Lagerauge 31 versehen.In the exemplary embodiment shown in FIGS. 3 to 6, the door holding rod 30 is likewise formed by an extruded part and the latching or. Brake ramps 10 and 20 are also arranged in the longitudinal center of the door holding rod 30. With regard to the braking ramp 20 which extends over a greater length of the door holding rod 30, however, a different design is shown here, in that the underside 21 of the braking ramp 20 is only connected linearly to the adjacent smooth-surface areas 40 and 50 via short sections 22, the transitions 120 forming a right angle or being equipped with a small radius that cannot be represented in the drawing. On both sides of the sections 22, the braking ramp 20 is connected to the adjacent smooth-surface areas 40 and 50 by means of webs 23 which are directed essentially transversely to their longitudinal extent, the webs 23 being at least on the inside in a radius 110 or 112 into the inner surfaces 130 and 140 of the exit Pass over flat material cut such that the inner cross-sectional profile has a rounded U-shape. The outer surfaces 170 and 180 of the smooth-surface areas 40 and 50 are adjoined by the side surfaces of the braking ramp 20 which are perpendicular to these, at right angles or with a small radius which cannot be represented in the drawing.
In the embodiments according to FIGS. 1, 3 and 4, the door holding rod 3 or 30 is provided with a bearing eye 31 which is angled perpendicular to its general plane.
