Description

Die Erfindung betrifft eine längenverstellbare Gestängekupplung, insbe­sondere von Treibstangenbeschlägen für Fenster, Türen od. dgl., bei welcher am Ende des einen von zwei miteinander zu kuppelnden Gestängen ein im Querschnitt U-förmiger Kupplungsschuh vorgesehen ist, der als Stanz-Biege­teil ausgebildet und dabei an der Innenseite wenigestens eines Schenkels mit einer beim Herstellen eingeformten Feinzahnung versehen ist, während das andere Gestänge zumindest an der zum Kuppeln bestimmten Schmal­seite über einen größeren Längenbereich eine komplementäre Feinzahnung aufweist, mit der sie zwischen die Schenkel des Kupplungsschuhs einlegbar ist und bei welcher die Feinzahnung des einstückig an das Gestänge ange­formten Kupplungsschuhs durch Prägepressen gebildet ist.The invention relates to a length-adjustable linkage coupling, in particular drive rod fittings for windows, doors or the like. In which at the end of one of two linkages to be coupled together a cross-sectionally U-shaped coupling shoe is provided, which is designed as a stamped and bent part and thereby the inside of at least one leg is provided with a fine toothing formed during manufacture, while the other linkage, at least on the narrow side intended for coupling, has a complementary fine toothing over a larger length range, with which it can be inserted between the legs of the coupling shoe and in which the fine toothing of the is formed integrally on the linkage coupling shoe by stamping presses.

Es ist bereits eine längenverstellbare Gestängekupplung von Treibstangen­beschlägen für Fenster, Türen od. dgl. der vorgenannten Art durch die DE-PS 26 35 446 bekannt. Sie hat sich auch im praktischen Einsatz wegen ihrer hohen Formfestigkeit bestens bewährt.A length-adjustable linkage coupling of connecting rod fittings for windows, doors or the like of the aforementioned type is already known from DE-PS 26 35 446. It has also proven itself in practical use due to its high dimensional stability.

Bei der längenverstellbaren Gestängekupplung nach diesem Stand der Technik muß das den Kupplungssschuh aufweisende Gestänge durch Prägepressen aus einem Blechzuschnitt gefertigt werden, welcher im Bereich des herzu­stellenden U-förmigen Kupplungsschuhs beidseitig einen über die normale Breite des Gestänges vorstehenden Flügel hat, dessen Breite jeweils etwa der späteren Höhe des hiervon gebildeten U-Schenkels des fertigen Kupplungs­schuhs entspricht. Das Ausgangsmaterial zur Herstellung des mit dem Kupplungs­schuh versehen Gestänges muß daher eine entsprechend größere Breite aufweisen als das später fertiggestellte Gestänge.In the length-adjustable linkage coupling according to this prior art, the linkage having the clutch shoe must be embossed by means of stamping presses be made from a sheet metal blank, which in the area of the U-shaped coupling shoe to be produced has on both sides a wing projecting beyond the normal width of the linkage, the width of which wing corresponds approximately to the later height of the U-leg of the finished coupling shoe formed therefrom. The starting material for the production of the linkage provided with the coupling shoe must therefore have a correspondingly larger width than the linkage which was produced later.

Es ist zwar durch die DE-OS 26 35 708 auch bereits der Vorschlag ge­macht worden, den Kupplungsschuh durch Prägepressen aus einem Blech­zuschnitt für sich allein herzustellen und anschließend mit dem Gestänge­teil, beispielsweise durch Vernieten, zu verbinden. Auch bei dieser Ferti­gungsart werden jedoch die Blechzuschnitte für die Kupplungsschuhe aus Blechstreifen hergestellt, deren Ausgangsabmessungen wesentlich größer sind als der zur Herstellung des Kupplungsschuhs benötigte Blechzuschnitt.DE-OS 26 35 708 has already made the proposal to manufacture the clutch shoe for itself by stamping presses from a sheet metal blank and then to connect it to the rod part, for example by riveting. In this type of production, too, however, the sheet metal blanks for the clutch shoes are produced from sheet metal strips, the starting dimensions of which are considerably larger than the sheet metal blank required for producing the clutch shoe.

Zur Herstellung von Gestängen mit einstückig angeformten Kupplungsschuhen, die an der inneren Längskante jeweils eine Feinzahnung aufweisen, hat man gemäß DE-GM 76 03 047 zwar auch bereits Flachmaterial, insbeson­dere Bandstahl, benutzt, welches bzw. welcher auf der ganzen Länge gleich­bleibende Breite aufweist. Zur Bildung des Kupplungsschuhs sind dabei in der Nähe der Enden der Bandstahlstreifen randseitig über deren Breitseite vorstehende Stege ausgeformt, die durch etwa bügelartig aus dem Material hochgeprägte Leisten gebildet werden, deren Innenkante unmittelbar aus einer zahnförmigen Schnittfläche besteht.According to DE-GM 76 03 047, flat material, in particular strip steel, which has a constant width over the entire length, has already been used to produce rods with integrally molded coupling shoes which each have fine teeth on the inner longitudinal edge. To form the coupling shoe near the ends of the strip steel strips are formed on the edge on their broad side protruding webs, which are formed by approximately bow-shaped strips embossed from the material, the inner edge of which consists directly of a tooth-shaped cut surface.

Diese bekannte längenverstellbare Gestängekupplung eignet sich zwar zur formschlüssigen Verbindung zweier sich teilweise überlappender Stulpschienen-­Abschnitte von Treibstangenbeschläge, die im übrigen an einem Trägerbauteil, beispielsweise an Flügel eines Fensters oder einer Tür, jeweils durch mehrere Schrauben gegen Verschieben festgelegt werden.This known length-adjustable linkage coupling is indeed suitable for the positive connection of two partially overlapping faceplate sections of espagnolette fittings, which are otherwise fixed to a support component, for example, to the sash of a window or a door, in each case by several screws against displacement.

Es ist zwar auch schon vorgeschlagen worden (siehe DE-GM 83 24 586), Kupplungsschuhe der durch das DE-GM 76 03 047, z.B. für die Verbindung der Stulpschienen von Treibstangenbeschlägen, bekannt gewordenen Art zur Bildung längenverstellbarer Gestängekupplungen zwischen verschiebbaren Treibstangen solcher Treibstangenbeschläge in Benutzung zu nehmen. Da in diesem Falle aber die Kupplungsschuhe ständig wechselnden Längsschubkräften unterliegen, hat sich gezeigt, daß bei einer nicht immer zu vermeidenden Schwergängigkeit der Beschläge unerwünschte Beschädigungen oder zumindest Verformungen an den Kupplungsschuhen auftreten können, die den Dauergebrauch der hiermit ausgerüsteten Treibstangenbeschläge nachhaltig beeinträchtigen.Although it has already been proposed (see DE-GM 83 24 586), clutch shoes by DE-GM 76 03 047, e.g. for connecting the faceplate of espagnolette fittings, to become known type for the formation of length-adjustable link couplings between displaceable espagnolettes of such espagnolette fittings. However, since in this case the clutch shoes are subject to constantly changing longitudinal thrust forces, it has been shown that if the fittings are not always difficult to avoid, undesirable damage or at least deformations to the clutch shoes can occur, which have a lasting effect on the continuous use of the drive rod fittings equipped with them.

Der Erfindung liegt die Aufgabe zugrunde, eine Gestängekupplung der ein­gangs angegebenen Art zu schaffen, bei der zur Herstellung des den Kupp­lungsschuh aufweisenden Gestänges ein Flachmaterialstreifen, insbesondere ein Bandstahlstreifen, als Ausgangsmaterial benutzt werden kann, welcher auf seiner ganzen Länge gleiche Breitenabmessung hat. Dabei soll jedoch der Kupplungsschuh innerhalb der Ausgangsbreite des Bandmaterials mit über seine eine Breitseite vorstehenden, auf ihre ganze Länge einstückig fest an das Gestänge angebundenen U-Schenkeln versehen sein, die an ihrer Innenfläche die eingeformte Feinzahnung aufweisen.The invention has for its object to provide a linkage coupling of the type specified, in which a flat material strip, in particular a strip of steel strip, can be used as the starting material for the manufacture of the linkage having the coupling shoe, which has the same width dimension over its entire length. However, the coupling shoe is to be provided within the initial width of the band material with U-legs projecting over its broad side and integrally connected to the linkage over its entire length and having the molded fine toothing on its inner surface.

Diese Aufgabe wird nach der Erfindung durch die Kennzeichnungsmerkmale des ersten Anspruchs gelöst, nämlich dadurch, daß der Gestängequerschnitt im Bereich des Kupplungsschuhs in seiner Dicke vermindert und in seiner Breite entsprechend vergrößert ist, daß die Feinzahnung mit ihrem Profil sich quer über die gesamte Breite des in seiner Dicke verminderten Treibstangenabschnitts erstreckt, und daß die über die Breite des normalen Treibstangenquerschnitts hinaus­ragenden Seitenflügel des in der Dicke verminderten Treibstangenabschnitts wenigstens annähernd um 90° zur Treibstangenebene hochgestellt sind.This object is achieved according to the invention by the characterizing features of the first claim, namely in that the linkage cross section in the area of the coupling shoe is reduced in thickness and increased in width accordingly, that the fine toothing with its profile extends across the entire width of the of its reduced drive rod section, and that the side wings of the reduced drive rod section projecting beyond the width of the normal drive rod cross section are raised at least approximately 90 ° to the drive rod plane.

Es hat sich gezeigt, daß die zur Bildung der U-Schenkel des Kupplungsschuhs erforderlichen, über die Breite des normalen Treibstangenquerschnitts hin­ ausragenden Seitenflügel durch entsprechend starkes Flachdrücken eines kurzen Endabschnitts des Ausgangsmaterials gebildet und mit der Feinzahung versehen werden können, ohne das die Gebrauchsfähigkeit des Kupplungs­schuhs beeinträchtigt ist. Die durch das Flachdrücken bewirkte Material­verfestigung stellt nämlich sicher, daß der U-förmige Kupplungsschuh auch bei einer gegenüber dem normalen Treibstangenquerschnitt verminderten Wanddicke eine Formfestigkeit erhält, die um ein Mehrfaches höher liegt, als im Falle der bügelartig aus der Flachmaterialebene über dessen Breit­seite hochgeformten Stege.It has been shown that the required to form the U-legs of the clutch shoe across the width of the normal drive rod cross-section protruding side wings can be formed by pressing a short end section of the starting material accordingly flat and provided with the fine toothing without the serviceability of the clutch shoe being impaired. The material consolidation caused by the flattening ensures that the U-shaped coupling shoe, even with a reduced wall thickness compared to the normal drive rod cross-section, has a form strength that is several times higher than in the case of the webs, which are shaped like a bow from the flat material level over its broad side.

Besonders bewährt hat sich nach der Erfindung eine Ausgestaltung, die gemäß Anspruch 2 darin besteht, daß die Gesamtdicke des in seiner Dicke verminderten Gestängeabschnitts etwa dem Doppelten der Profilhöhe der Feinzahnung entspricht und dabei die Profilhöhe der Feinzahnung etwa gleich einem Drittel der Dicke des normalen Gestängequerschnitts ausgeführt ist.A design that has proven particularly useful according to the invention is that the overall thickness of the rod section reduced in thickness corresponds to approximately twice the profile height of the fine toothing and the profile height of the fine toothing is approximately equal to one third of the thickness of the normal rod cross-section is.

Als zweckmäßig hat es sich weiterhin erwiesen, wenn nach Anspruch 3 die gestreckte Breite des in seiner Dicke verminderten Gestängeabschnitts wenigstens annähernd doppelt so groß bemessen ist, wie die Dicke des normalen Gestängequerschnitts. Hierdurch lassen sich die beiden Schenkel des im Querschnitt U-förmigen Kupplungsschuhs um ein Maß über die Breitseite des Gestänges hochstellen, welches etwa ihrer normalen Querschnittsdicke entspricht. Ein mit dem Kupplungsschuh in Eingriff bringbares, benachbartes Gestänge, das an seinen Schmalseiten mit der Feinzahnung versehen ist, wird daher über seine gesamte Querschnittshöhe hinweg vom Kupplungsschuh umfaßt.It has also proven to be advantageous if, according to claim 3, the stretched width of the rod section reduced in thickness is dimensioned at least approximately twice as large as the thickness of the normal rod cross-section. As a result, the two legs of the coupling shoe, which is U-shaped in cross section, can be raised by an amount over the broad side of the linkage which corresponds approximately to its normal cross-sectional thickness. An adjacent linkage which can be brought into engagement with the coupling shoe and which is provided with fine teeth on its narrow sides is therefore encompassed by the coupling shoe over its entire cross-sectional height.

Ein anderes Ausgestaltungsmerkmal bei der erfindungsgemäßen Gestänge­kupplung liegt nach Anspruch 4 auch darin, daß das Profil der Feinzahnung in dem zum normalen Gestängequerschnitt parallelen Stegabschnitt des Kupplungsschuhs zumindest teilweise flachgedrückt ist, um dort die Auflagefläche für die Breitseite des in den Kupplungsschuh eingerückten, benachbarten Gestänges entsprechend zu vergrößern.Another design feature of the linkage coupling according to the invention is also according to claim 4 that the profile of the fine toothing is at least partially flattened in the web section of the coupling shoe parallel to the normal linkage cross section, in order to achieve the Increase the contact area for the broad side of the adjacent linkage that is inserted into the coupling shoe.

Ein erfindungsgemäßes Verfahren zur Herstellung einer längenverstellbaren Gestängekupplung zeichnet sich nach Anspruch 5 hauptsächlich dadurch aus, daß das Zahnprofil der Feinzahnung unmittelbar mit dem Flachdrücken des Treibstangenquerschnitts ausgeformt wird und daran anschließend die beiden Seitenflügel des flachgedrückten Querschnittsbereichs aus der Ge­stängeebene hochgestellt werden.A method according to the invention for producing a length-adjustable rod coupling is mainly characterized in that the tooth profile of the fine toothing is formed directly with the flattening of the drive rod cross section and then the two side wings of the flattened cross-sectional area are then raised from the rod plane.

Nach Anspruch 6 ist dabei weiterhin vorgesehen, daß der flachgedrückte Gestängequerschnitt mit seiner die Verzahnung aufweisenden Seitenfläche mindestens auf die Ebene der an sie anschließenden Breiteseite des normalen Gestängequerschnitts hochgekröpft wird.According to claim 6 it is further provided that the flattened rod cross-section with its toothed side surface is cranked at least to the level of the broad side adjoining it of the normal rod cross-section.

Schließlich hat es sich in verfahrenstechnischer Hinsicht als besonders vor­teilhaft herausgestellt, wenn nach der Lehre des Anspruchs 7 das Ausgangs­material entsprechend der doppelten Länge eines Kupplungsschuhs flachge­drückt und mit der Verzahnung versehen sowie daraufhin auf halber Länge der Verzahnung ein Trennschnitt vorgenommen wird, und zwar entweder bevor die Seitenflügel des flachgedrückten Gestängequerschnitts U- förmig hochgestellt werden, oder aber nachdem sie zuvor hochgestellt worden sind.Finally, it has proven to be particularly advantageous from a process engineering point of view if, according to the teaching of claim 7, the starting material is flattened corresponding to twice the length of a coupling shoe and provided with the toothing, and then a cut is made halfway along the toothing, either before the Side wings of the flattened linkage cross section can be raised in a U-shape, or after they have been raised previously.

Ein zweites Gestänge, beispielsweise ebenfalls eine Treibstange 6, besteht aus im Querschnitt rechteckförmigem Flachmaterial und ist wenigestens an einer, vorzugsweise aber an beiden Schmalseiten mit einer Feinzahnung 7 ausgestattet, die der Feinzahnung 5 komplementär ist. Die Treibstange 6 kann an jeder beliebigen Stelle ihres mit der Feinzahnung 7 versehenen Längenbereichs von oben her formschlüssig in die Feinzahnung 5 des U-­förmigen Kupplungsschuhs 3 an der Treibstange 2 eingerückt werden. Da hierbei die Treibstange 6 an ihren Schmalseiten von den beiden Schenkeln 4 des Kupplungsschuhs 3 umgriffen wird, können die bei gemeinsamer Längs­verschiebung der Treibstangen 2 und 6 auftretenden Querkräfte sicher vom Kupplungsschuh 3 aufgenommen werden, ohne daß die Kupplungsverbindung außer Eingriff kommen kann.A second linkage, for example also a drive rod 6, consists of flat material with a rectangular cross section and is equipped at least on one, but preferably on both narrow sides with fine teeth 7, which is complementary to the fine teeth 5. The drive rod 6 can be positively inserted from above into the fine toothing 5 of the U-shaped coupling shoe 3 on the drive rod 2 at any point of its length range provided with the fine toothing 7. Since here the drive rod 6 is encompassed on its narrow sides by the two legs 4 of the clutch shoe 3, the transverse forces which occur when the drive rods 2 and 6 are displaced longitudinally can be transmitted safely Coupling shoe 3 are added without the coupling connection can come out of engagement.

Wesentlich bei der in Fig. 1 dargestellten, längenverstellbaren Gestänge­kupplung 1 ist, daß der im Querschnitt U-förmige Kupplungsschuh 3 aus dem gleichen Material besteht, aus dem auch die Treibstange 2 gefertigt ist, nämlich aus einem Bandstahlstreifen. Es kommt nämlich darauf an, Treibstange 2 und Kupplungsschuh 3 in einem Stück zu fertigen, wobei der Boden oder Steg 8 des Kupplungsschuhs 3 zumindest mit der oberen Breitseite der Treibstange 2 auf gleicher Ebene liegen soll.It is essential in the length-adjustable rod coupling 1 shown in FIG. 1 that the coupling shoe 3, which is U-shaped in cross section, is made of the same material from which the drive rod 2 is made, namely of a strip of steel strip. It is important to manufacture the connecting rod 2 and the coupling shoe 3 in one piece, the bottom or web 8 of the coupling shoe 3 being at least at the same level as the upper broad side of the connecting rod 2.

Die Treibstange 2 ist zusammen mit dem Kupplungsschuh 3 als Stanz-Biege­teil gefertigt, wobei der Kupplungsschuh 3 insgesamt, also mit seinen beiden Schenkeln 4, dem Boden bzw. Steg 8 und den Feinzahnungen 5 durch einen Prägepreßvorgang hergestellt ist.The drive rod 2 is manufactured together with the clutch shoe 3 as a stamped and bent part, the clutch shoe 3 as a whole, that is to say with its two legs 4, the base or web 8 and the fine teeth 5 being produced by an embossing press process.

Der Prägepreßvorgang wird an einem vorgegebenen Längenabschnitt 11 eines das Ausgangsmaterial bildenden Bandstahlstreifens 12 od. dgl. ausge­führt, der über seine gesamte Länge hinweg gleiche Breite 13 hat, welche mit der Querschnittsbreite der Treibstange 2 übereinstimmt.The embossing process is carried out on a predetermined length section 11 of a strip steel strip 12 or the like which forms the starting material and has the same width 13 over its entire length, which corresponds to the cross-sectional width of the drive rod 2.

Durch den Prägepreßvorgang wird dabei der Bandstahlstreifen 12 auf dem Längenabschnitt 11 in seiner Querschnittsdicke so verringert, daß er eine Querschnittsbreite 14 annimmt, die etwa doppelt so groß bemessen werden kann, wie die Ausgangsbreite 13 des Bandmaterialstreifens 12.Through the embossing process, the strip steel strip 12 on the length section 11 is reduced in its cross-sectional thickness so that it assumes a cross-sectional width 14 which can be dimensioned approximately twice as large as the starting width 13 of the strip material strip 12.

Bei diesem Prägepreßvorgang werden gleichzeitig auch die Zahnlücken 15 der Feinzahnungen 5 in Form von vertieften Preßmarken in die verminderte Werkstoffdicke des Längenabschnitts 11 eingearbeitet, und zwar in der Weise, daß die Kopfflächen der zwischen zwei aufeinanderfolgenden Zahn­lücken 15 entstehenden Zähne 16 in der Ebene des in seiner Querschnitts­dicke verminderten Längenabsschnitts 11 verbleiben.In this embossing process, the tooth gaps 15 of the fine teeth 5 in the form of recessed press marks are simultaneously incorporated into the reduced material thickness of the length section 11, in such a way that the top surfaces of the teeth 16 formed between two successive tooth gaps 15 are in the plane of the tooth Cross-sectional thickness reduced section 11 remain.

Die durch den Prägepreßvorgang gebildeten Zahnlücken 15 erstrecken sich dabei über die gesamte Breite 14 des in seiner Dicke verminderten Längen­abschnitts 11, wie das deutlich in Fig. 5 erkennbar ist.The tooth gaps 15 formed by the embossing process extend over the entire width 14 of the reduced length section 11, as can be clearly seen in FIG. 5.

In einem dem Prägepreßvorgang unmittelbar nachfolgenden Arbeitsschritt werden die beidseitig um das Maß 17 über die normale Querschnittsbreite 13 des Stahlbandstreifens 12 vorstehenden Seitenflügel 18 des Längen-abschnitts 11 wenigstens annähernd um 90° aus der normalen Querschnittsebene hoch­gestellt, so daß dadurch die beiden Schenkel 4 des Kupplungsschuhs 3 mit der an ihrer Innenseite liegenden Feinzahnung 5 entstehen, wie das die Fig. 6 erkennen läßt.In a work step immediately following the embossing process, the side wings 18 of the length section 11 projecting on both sides by the dimension 17 over the normal cross-sectional width 13 of the steel strip strip 12 are raised at least approximately 90 ° from the normal cross-sectional plane, so that thereby the two legs 4 of the coupling shoe 3 arise with the fine toothing 5 lying on its inside, as can be seen in FIG. 6.

Das Hochstellen der Seitenflügel 18 erfolgt dabei zweckmäßigerweise so, daß die Außenflächen der beiden Schenkel 4 des Kupplungsschuhs 3 zumindest annähernd in gleicher Flucht mit den Schmalseiten 19 des Bandstahlstreifens 12 bzw. der Treibstange 2 zu liegen kommen.The raising of the side wings 18 is expediently such that the outer surfaces of the two legs 4 of the coupling shoe 3 come to lie at least approximately in the same alignment with the narrow sides 19 of the steel strip 12 or the drive rod 2.

Für das Hochstellen der Seitenflügel 18 zu den Schenkeln 4 des Kupplungs­schuhs 3 kann eine Biegematrize zum Einsatz gelangen, die an ihrer Stirn­fläche im wesentlichen eben ausgebildet ist, aber an ihren Längsseiten­flächen Profilierungen hat, die den Zahnlücken 15 und den Zähnen 16 ent­sprechen. Damit wird beim Hochstellen der Seitenflügel 18 zu den Schenkeln 4 des Kupplungsschuhs 3 einerseits erreicht, daß deren innenseitige Fein­zahnungen 5 während der Biegeverformung ihre exakte Querausrichtung zur Längsachse de Treibstange beibehalten. Andererseits werden jedoch die im Bereich des Bodens bzw. Steges 8 des Kupplungsschuhs 3 verblei­benden Bereiche der Zähne 16 zumindest teilweise flachgedrückt, so daß sich ihre Kopfflächen gegenüber den Kopfflächen der Feinzahnungen 5 ver­breitern, während die Zahnlücken 15 sich dort entsprechend verengen (Fig.3).For the raising of the side wings 18 to the legs 4 of the clutch shoe 3, a bending die can be used which is essentially flat on its end face, but has profiles on its longitudinal side faces which correspond to the tooth gaps 15 and the teeth 16. Thus, when the side wings 18 are raised to the legs 4 of the clutch shoe 3, on the one hand, their fine toothing 5 on the inside maintains their exact transverse alignment with the longitudinal axis de drive rod during the bending deformation. On the other hand, however, the areas of the teeth 16 remaining in the area of the bottom or web 8 of the clutch shoe 3 are at least partially flattened, so that their head surfaces widen compared to the head surfaces of the fine teeth 5, while the tooth gaps 15 narrow there accordingly (FIG. 3) .

Das das Hochstellen der Seitenflügel 18 zu den Schenkeln 4 des Kupplungs­schuhs 3 bewirkende Biegewerkzeug kann eine solche Ausbildung erhalten, daß es den Boden bzw. Steg 8 des Kupplungsschuhs 3 gegenüber der unteren Breitseite des Bandmaterialstreifens 12 bzw. der Treibstange 2 so weit nach oben verkröpft, daß die Innenfläche des Bodens bzw. Steges 8 min­destens auf gleiche Ebene mit der oberen Breitseite des Bandmaterialstreifens 12 bzw. der Treibstange 2 gelangt.The bending tool which causes the side wings 18 to rise to the legs 4 of the clutch shoe 3 can be designed in this way, that it cranks the bottom or web 8 of the coupling shoe 3 relative to the lower broad side of the strip material strip 12 or the drive rod 2 so far upwards that the inner surface of the bottom or web 8 is at least on the same level with the upper broad side of the strip material strip 12 or the drive rod 2 arrives.

In den Fig. 5 und 6 ist eine besonders vorteilhafte Fertigungsart für ein­stückig mit einem Kupplungsschuh 3 ausgestattete Treibstangen 2 gezeigt.5 and 6 show a particularly advantageous type of manufacture for drive rods 2 which are provided in one piece with a clutch shoe 3.

Der durch den Prägegpreßvorgang flachgedrückte und verbreiterte Längen­abschnitt 11 ist dort nämlich so bemessen, daß er die gleichzeitige Bildung zweier Kupplungsschuhe 3 mit daran anschließenden Treibstangen 2 ermög­licht, wenn dafür Sorge getragen ist, daß auf halber Länge des Längen­abschnitts 11 in den Seitenflügeln 18 Ausklinkungen 20 liegen, in deren Breich die hochgestellten Schenkel 4 der Kupplungsschuhe 3 unterbrochen sind. In diesem Bereich kann dann ein Trennmesser 21 wirksam werden, wie das in Fig. 7 angedeutet ist. Nach dem Schnitthub desselben sind dann zwei Treibstangen 2 mit je einem Kupplungsschuh 3 in zueinander spiegel­bildlicher Lage fertiggestellt.The flattened and widened length section 11 by the embossing process is dimensioned there in such a way that it enables the simultaneous formation of two coupling shoes 3 with adjoining connecting rods 2 if care is taken to ensure that notches 20 are located in the side wings 18 halfway along the length 11 , in the area of which the raised legs 4 of the clutch shoes 3 are interrupted. A separating knife 21 can then be effective in this area, as is indicated in FIG. 7. After the cutting stroke of the same, two connecting rods 2, each with a coupling shoe 3 in a mirror-inverted position, are completed.

Die Ausgestaltung des Kupplungssschuhs 3 an einer solchen Treibstange 2 zeigen die Fig. 2 bis 4 der Zeichnung jeweils in vergrößertem Maßstab. Dabei ist insbesondere erkennbar, daß die Gesamtdicke 9 der Schenkel 4 und des Bodens bzw. Steges 8 am Kupplungsschuh 3 etwa zwei Dritteln der Materialdicke 10 der Treibstange 2 entspricht. Darüberhinaus wird aber, besonders aus den Fig. 2 und 4, deutlich, daß die Zahnlücken 15 der Fein­zahnungen 5 eine Tiefe und demzufolge die Zähne 16 derselben eine Höhe haben, die etwa der halben Gesamtdicke 9 der Schenkel 4 des Kupplungs­schuhs 3 entspricht.The design of the clutch shoe 3 on such a drive rod 2 is shown in FIGS. 2 to 4 of the drawing, each on an enlarged scale. It can be seen in particular that the total thickness 9 of the legs 4 and the bottom or web 8 on the coupling shoe 3 corresponds to approximately two thirds of the material thickness 10 of the drive rod 2. Furthermore, it is clear, particularly from FIGS. 2 and 4, that the tooth gaps 15 of the fine teeth 5 have a depth and consequently the teeth 16 thereof have a height which corresponds to approximately half the total thickness 9 of the legs 4 of the coupling shoe 3.

In Fig. 3 ist schließlich auch noch andeutet, daß durch Flachdrücken der Zähne 16 am Boden bzw. Steg 8 des Kupplungsschuhs 3 deren Kopfflächen eine jeweils vergrößerte Stützauflage für die einzurückende Treibstange 6 bilden, indem eine Verengung der zwischen den Zähnen 16 vorhandenen Zahnlücken 15 eingetreten ist.In Fig. 3 is finally also indicated that flattening the teeth 16 on the bottom or web 8 of the clutch shoe 3, the top surfaces form a respectively enlarged support pad for the drive rod 6 to be engaged by narrowing the tooth gaps 15 present between the teeth 16.

Wenn relativ kurze Gestänge, insbesondere Treibstangen 2 benötigt werden, können diese auch aus Bandmaterialstreifen quer zu deren Längsrichtung mit ihrer normalen Querschnittsbreite ausgestattet werden, bevor an ihnen der Prägepreßvorgang ausgeführt wird. Die zur Herstellung dieser kurzen Gestänge bzw. Treibstangen benutzten Stanzpressen können in diesem Falle dann mit großen Hubzahlen arbeiten und ermöglichen dadurch eine kosten­günstige Massenfertigung.If relatively short rods, in particular drive rods 2, are required, they can also be provided with strips of strip material transverse to their longitudinal direction with their normal cross-sectional width before the embossing process is carried out on them. The punch presses used to produce these short rods or drive rods can then work with large numbers of strokes and thereby enable inexpensive mass production.
