Description

Die Erfindung betrifft eine längenverstellbare Verbindung für ein Gestänge nach dem Oberbegriff des Anspruchs 1.The invention relates to a length-adjustable connection for a linkage according to the preamble of claim 1.

Derartige Längenverstellungen sind in vielfältiger Ausgestaltung bereits bekannt und realisiert. Gattungsgemäße Verbindungen lassen sich auf Treibstangengestänge von Fenstern und Türen anwenden, werden aber auch bei Möbelbeschlägen zur Kopplung eingesetzt und dienen im Wesentlichen der Längenjustierung zweier Bauteile, die nach dem Fügen miteinander formschlüssig starr miteinander gekoppelt bleiben.Such length adjustments are already known and realized in various embodiments. Generic compounds can be applied to espagnolette of windows and doors, but are also used in furniture fittings for coupling and serve essentially the length adjustment of two components that remain positively coupled to each other after joining with each other.

Die DE 2635446 A1 offenbart das Beispiel einer längenverstellbaren Gestängekupplung für einen Treibstangenbeschlag an Fenstern oder Türen. Diese Treibstangenbeschläge müssen an die Größe des Flügels angepasst werden und bestehen aus längenanpassbaren und längenstarren Beschlagteilen. Die längenstarren Beschlagteile besitzen eine Treibstange mit einem U-förmigen Kupplungsschuh an deren Ende. Der Kupplungsschuh ist an den aufeinander zuweisenden Innenseiten mit einer Zahnung versehen, die senkrecht zur Ebene des flachrechteckigen Querschnitts der Stage verlaufen.The DE 2635446 A1 discloses the example of a length adjustable linkage coupling for a driving rod fitting on windows or doors. These espagnolette fittings must be adapted to the size of the wing and consist of length-adjustable and length-rigid fitting parts. The rigid fitting parts have a drive rod with a U-shaped coupling shoe at the end. The clutch shoe is provided on the mutually facing inner sides with a toothing, which extend perpendicular to the plane of the flat rectangular cross-section of the stage.

Die DE 2515542 C3 offenbart ein längenverstellbares Gestänge, bei dem eine erste flachrechteckige Stange entlang ihrer Längsflächen eine Zahnung aufweist, die quer zu den Längsflächen verlaufende Zähne besitzt. Damit verlaufen die Zähne senkrecht zu den Breitseiten des Rechteckquerschnitts und ermöglichen eine Montage mit einem U-förmigen Verbindungsstück senkrecht zu dieser Ebene. Das U-förmige Verbindungsstück ist an den Innenflächen der aufrecht zu einer zweiten rechteckigen Stange aufgestellten Schenkeln mit einer komplementären Zahnung versehen. Die Stangen lassen sich dadurch formschlüssig koppeln und die Kopplung kann Zug- und Druckkräfte übertragen. Hierbei sind an der ersten Stange hintereinander liegende Verzahnungsabschnitte vorgesehen, die jeweils der Länge des Verbindungsstücks entsprechen und einen Abstand zueinander haben, der geringer bemessen ist als die Länge des Verbindungsstücks. Gleichzeitig ist die Breite der Stange im Bereich des Abstandes zwischen den Verzahnungsabschnitten entsprechend der Breite ausgelegt, welche diese Stange im Bereich der Zahntäler der Verzahnungsabschnitte hat. Dadurch kann das Verbindungsstück auch die erste Stange an den nicht mit einer Verzahnung versehenen Abschnitten umgreifen und stellt einen Formschluss sicher. Die Ausgestaltung bewirkt, dass im Verhältnis zur Gesamt-Verzahnungslänge eine deutlich reduzierte Schnittstempel-Länge erforderlich ist, deren Herstellung vereinfacht wird. Die Gesamtlänge der Verzahnung lässt sich über die Anzahl der Schnittstempel leicht anpassen. Die Zahnungen sind an beiden Schmalseiten vorgesehen und jeweils versetzt zueinander angebracht. Auch die Schnittkraft kann durch die Realisierung dieser Ausgestaltung verringert werden.The DE 2515542 C3 discloses a length-adjustable linkage in which a first flat rectangular bar along its longitudinal surfaces has a toothing, which has transverse to the longitudinal surfaces extending teeth. Thus, the teeth are perpendicular to the broad sides of the rectangular cross-section and allow mounting with a U-shaped connector perpendicular to this plane. The U-shaped connector is provided on the inner surfaces of the erected upright to a second rectangular rod legs with a complementary toothing. The rods can thereby be positively coupled and the coupling can transmit tensile and compressive forces. In this case, on the first rod one behind the other toothing sections are provided, each corresponding to the length of the connecting piece and have a distance from one another, which is dimensioned smaller than the length of the connecting piece. At the same time, the width of the rod is in the range of Distance between the toothed sections designed according to the width, which has this rod in the region of the tooth valleys of the toothed portions. As a result, the connecting piece can embrace the first rod on the sections not provided with a toothing and ensures positive locking. The design causes that in relation to the total toothing length a significantly reduced cutting punch length is required, the production is simplified. The total length of the teeth can be easily adjusted by the number of cutting punches. The serrations are provided on both narrow sides and each offset from one another. The cutting force can be reduced by the realization of this embodiment.

Aus der FR 2403441 A1 ist es bekannt, auch nach der Montage ortsfeste benachbarte Stulpschienen zu koppeln, in dem eine erste Stulpschiene über einen Teillängenbereich mit einer Verzahnung an der Schmalseite der flachrechteckigen Stulpschiene versehen ist. In diese greift ein überlappendes Kopplungsglied einer benachbarten zweiten Stulpschiene ein und bewirkt eine zug- und druckfeste Verbindung, welche eine Relativverlagerung der benachbarten Stulpschienen, welche über das Kopplungsglied überlappt werden; verhindert.From the FR 2403441 A1 It is known to couple stationary adjacent cuff rails even after installation, in which a first cuff rail is provided over a partial length region with a toothing on the narrow side of the flat rectangular cuff rail. In this engages an overlapping coupling member of an adjacent second faceplate and causes a tension and compression-resistant connection, which a relative displacement of the adjacent cuff rails, which are overlapped on the coupling member; prevented.

Die DE 7209926 U1 sieht zur erleichterten Kopplungsverbindung der ersten Stange mit dem Verbindungsstück einen Einschwenkvorgang bei der Montage vor. Die über einen Teillängenbereich mit einer Zahnung versehene Stange ist dazu hochkant angeordnet und greift dadurch in einer größeren Tiefe in das U-förmige Verbindungsstück ein. Eine zweite flachrechteckige Stange hinterfüttert die erste Zahnstange und stützt diese gegen den zweiten U-Schenkel des Verbindungsstücks ab, um ein Entkoppeln der Zahnung der ersten Stange zu verhindern.The DE 7209926 U1 For easier coupling connection of the first rod with the connector before a Einschwenkvorgang during assembly. The over a partial length region provided with a toothed rod is arranged edgewise and thereby engages in a greater depth in the U-shaped connector. A second flat-rectangular bar backfests the first rack and supports it against the second U-leg of the connector to prevent decoupling of the teeth of the first bar.

Die DE 2635708 A1 zeigt die besondere Gestaltung des Verbindungsstücks als Stanzteil. In Bezug auf die Kopplung der Gestänge entspricht diese der DE 1093698 A . Schließlich zeigt die DE 19828267 A1 eine von einem rechteckigen Querschnitt abweichende Form der Stangen. Diese sind U-förmiger Ausgestaltung und aus dünnwandigem Blech hergestellt. In welcher Art die Kopplung erfolgen soll, ist nicht offenbart.The DE 2635708 A1 shows the special design of the connector as a stamped part. In terms of the coupling of the linkage this corresponds to the DE 1093698 A , Finally, the shows DE 19828267 A1 a deviating from a rectangular cross section shape of the rods. These are U-shaped design and made of thin-walled sheet metal. The type in which the coupling is to take place is not disclosed.

Die genannten Ausgestaltungen sind insgesamt bewährt und lassen sich durch Stanzen kostengünstig herstellen. Allerdings sind die Werkzeuge zur Herstellung, insbesondere bei längeren Verzahnungsbereichen, an die dann gesteigerten Werkzeugdrücke anzupassen und gestalten sich dadurch teuer. Zudem sind die erforderlichen Maschinen an diese Erfordernisse hinsichtlich des Druckes anzupassen.The aforementioned embodiments are proven overall and can be produced inexpensively by punching. However, the tools for manufacturing, especially for longer toothing areas, to adapt to the then increased mold pressures and make it expensive. In addition, the required machines must be adapted to these requirements with regard to the pressure.

Ausgehend von dem bekannten Stand der Technik sucht die Erfindung nach einer Ausgestaltung, welche bei verbesserter Qualität der Zahnung ein geringeres Maß an Anforderungen an das Werkzeug und die Maschinen stellt.Starting from the known prior art, the invention seeks a configuration which, with improved quality of the toothing, places a lesser degree of demands on the tool and the machines.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, dass das erste Bauteil aus einem Halbzeug durch Stanzen hergestellt ist, welches über seine gesamte Länge mit Phasen entlang einer der Breitseiten versehen ist, sodass der Querschnitt einer rechteckigen Basis mit einer trapezförmigen Ergänzung entspricht.To achieve this object, the invention provides that the first component is made of a semifinished product by punching, which is provided over its entire length with phases along one of the broad sides, so that the cross section corresponds to a rectangular base with a trapezoidal complement.

Bedingt durch diese Ausgestaltung entsteht ein nicht-rechteckiger Querschnitt. Es liegen sich zwei breitere Ebenenflächen gegenüber. Bezogen auf die Längsmittelachse ist das Profil symmetrisch. Die Längsschmalseiten des Bauteils sind um den Betrag der Phasenabmessung reduziert. Für die Zug- und Drucksteifigkeit des Bauteils bedeutet die Phase keine nennenswerte Reduzierung. Die Reduzierung der Abmessung parallel zu den Schmalseiten führt aber zu einer deutlich reduzierten Querschnittsabmessung im Bereich der anzubringenden Zahnung.Due to this configuration creates a non-rectangular cross-section. There are two broader plane surfaces opposite. Relative to the longitudinal central axis, the profile is symmetrical. The longitudinal narrow sides of the component are reduced by the amount of the phase dimension. For the tensile and compressive stiffness of the component, the phase means no appreciable reduction. The reduction of the dimension parallel to the narrow sides, however, leads to a significantly reduced cross-sectional dimension in the region of the teeth to be attached.

Größere Werkstück-Querschnitte führen bei einem Stanzen im Allgemeinen dazu, dass die der Matrize zugewandte Werkstückseite einen Ausbruch aufweist, der durch plastische Verformungen des von dem Schneidstempel verdrängten Materials entsteht. Dem wird mit Matrizen begegnet, die der Form der Stanzkontur angepasst wird, was aber zu einem Ausbruch nahe der Materialmitte führt.Larger workpiece cross-sections generally result in punching in that the side of the workpiece facing the die has an outbreak that results from plastic deformation of the material displaced by the cutting punch. This is countered with matrices, which is adapted to the shape of the punching contour, but this leads to an eruption near the middle of the material.

Die Erfindung schafft hingegen in dem Bereich, in dem das Material durch den Schneidvorgang getrennt werden soll, eine gezielte und leicht anzubringende Material-Reduzierung.The invention, however, creates in the area in which the material is to be separated by the cutting process, a targeted and easy-to-install material reduction.

Im Ergebnis ist die Zahnung über ihre gesamte Höhe mit einer ausgeprägten Zahnflanke versehen und besitzt daher eine hohe Tragfähigkeit. Der Pressdruck kann reduziert werden.As a result, the toothing is provided over its entire height with a pronounced tooth flank and therefore has a high load capacity. The pressing pressure can be reduced.

Eine besonders vorteilhafte Ausgestaltung sieht vor, dass die verbleibende Abmessung der verkürzten Breitseite bezogen auf die gegenüberliegende, unbearbeitete Breitseite zwischen 50% und 70% beträgt. Es hat sich gezeigt, dass die Zahnflanken in diesem Spektrum eine gute Ausgestaltung erfahren.A particularly advantageous embodiment provides that the remaining dimension of the shortened broadside relative to the opposite, unprocessed broadside is between 50% and 70%. It has been shown that the tooth flanks undergo a good design in this spectrum.

Es ist ferner vorgesehen, dass das Maß der verkürzten Breitseite zwischen dem Maß an den Zahnungsspitzen und dem geringsten Maß im Zahnungsgrund liegt. Die Zahnung liegt dadurch mit einem Teil der Zahnung im Bereich der Fase und somit der Materialreduzierung.It is further contemplated that the measure of the shortened broadside is between the measure of the tooth tips and the smallest measure in the tooth root. The toothing is thus a part of the toothing in the area of the chamfer and thus the material reduction.

Die Erfindung ist besonders vorteilhaft, wenn das erste Bauteil eine Treibstange eines Treibstangenbeschlags ist, da hier besonders hohe Stückzahlen zu erwarten sind.The invention is particularly advantageous when the first component is a drive rod of a drive rod fitting, since particularly high quantities are to be expected here.

Dabei ist die Erfindung auch vorteilhaft, wenn das erste Bauteil eine Stulpschiene eines Treibstangenbeschlags ist.The invention is also advantageous if the first component is a faceplate of a drive rod fitting.

Für diesen Fall ist es auch von Vorteil, wenn das zweite Bauteil eine Stulpschienenkopplung ist.For this case, it is also advantageous if the second component is a Stulpschienenkopplung.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Figuren. Es zeigt:

Der in Fig. 1 dargestellt Querschnitt der Stange 1 zeigt die Querschnittsabmessungen entlang der Linie I-I in der Fig. 3. Die Stange 1 ist im Ausführungsbeispiel Teil einer längenverstellbaren Verbindung eines Gestänges, in der speziellen Ausgestaltung eines Treibstangenbeschlages. Dabei ist die Stange 1 ein erstes Bauteil, welches zur Verbindung mit einem zweiten Bauteil, welches im Wesentlichem einem Verbindungsstück nach der DE 2515542 C3 entspricht, kuppelbar. Dazu ist die Stange 1 über einen Längenabschnitt 2 mit einer Verzahnung 3 an den Schmalseiten 4, 5 versehen. In diese Verzahnung 3 greift das zweite Bauteil - das hier nicht dargestellte Verbindungstück - mit einer komplementären Innenverzahnung eines Kupplungsschuhs ein, sodass die Stange 1 und das zweite Bauteil in Längsrichtung bewegungsgekoppelt sind. Aus den Fign. 1 und 2b ist ersichtlich, dass der Querschnitt der Stange 1 über die gesamte Länge hinweg mit gegenüber einer der Längsmittelachsendicke 6 verringerten Seitenkantenstärke 7 versehen ist. Dadurch entstehen zwei unterschiedlich dimensionierte Breitseiten 8 und 9. Dies wird dadurch bewirkt, dass die Stange 1 aus einem Halbzeug durch Stanzen hergestellt ist, welches über seine gesamte Länge mit Fasen 10, 11 versehen ist. Es entsteht dadurch eine rechteckige Basis und eine trapezförmige Ergänzung. Die Fasen sind dabei symmetrisch zur Längsmittelachse 12 angebracht.The in Fig. 1 Cross-section of the rod 1 shows the cross-sectional dimensions along the line II in the Fig. 3 , The rod 1 is in the embodiment part of a length-adjustable connection of a linkage, in the special embodiment of a drive rod fitting. In this case, the rod 1 is a first component, which for connection to a second component, which essentially a connector after the DE 2515542 C3 corresponds, can be coupled. For this purpose, the rod 1 is provided with a toothing 3 on the narrow sides 4, 5 over a longitudinal section 2. In this toothing 3 engages the second component - not shown here connecting piece - with a complementary internal toothing of a coupling shoe, so that the rod 1 and the second component are coupled in the longitudinal direction movement. From the FIGS. 1 and 2b It can be seen that the cross-section of the rod 1 over the entire length is provided with respect to a Längmittelachsendicke 6 reduced side edge thickness 7. This results in two differently dimensioned broadsides 8 and 9. This is effected by the rod 1 is made of a semi-finished by punching, which is provided over its entire length with chamfers 10, 11. This creates a rectangular base and a trapezoidal complement. The chamfers are mounted symmetrically to the longitudinal central axis 12.

Im Ausführungsbeispiel nach Fig. 3 ist die Stange 1 eine Treibstange, die entlang des Längenabschnitts 2 mit der Verzahnung 3 versehen ist. Daran schließt sich ein Abschnitt 13 an, der frei von einer Verzahnung ist, gegenüber einem sich darauf folgenden Abschnitt 14 unbearbeiteter Breite 15 aber breitenreduziert ausgeführt ist. Im Abschnitt 14 ist ein Langloch 16 vorgesehen. Dessen Breite 17 ist so abgestimmt, dass diese geringer bemessen ist als das Maß 18 der Breitseite 8. Eine einseitige Erweiterung 19 dient zum Eingriff eines durch Bewegung der Treibstange abscherbaren Fixierungsglieds und ist so bemessen, dass der parallel zur Längsachse 20 verlaufende Rand der Erweiterung 19 an die Fase 10 heranreicht. Ein weiterer Längenabschnitt 20 ist in seiner Breite reduziert ausgeführt und weist eine Reihe von Durchbrechungen 21 auf. Die Durchbrechungen 21 dienen dem Eingriff eines Ritzels, während die Längskanten 22, 23 zur Führung in einem hier nicht dargestellten Gehäuse dienen, welches das Ritzel lagert. Der seitliche Beschnitt, durch den die Längskanten 22, 23 hergestellt werden, findet im Bereich der Fasen 10, 11 statt. Ein unbeschnittener Endbereich 24 schließt sich daran an.In the embodiment according to Fig. 3 the rod 1 is a drive rod which is provided along the longitudinal section 2 with the toothing 3. This is followed by a section 13, which is free of a toothing, compared to a subsequent section 14 unprocessed width 15 but is carried out with reduced width. In section 14, a slot 16 is provided. Whose width 17 is adjusted so that it is smaller than the dimension 18 of the broad side 8. A one-sided extension 19 is used to engage a shear-off by movement of the drive rod fixing member and is dimensioned such that the extending parallel to the longitudinal axis 20 extending edge of the extension 19 to the chamfer 10. Another length section 20 is designed reduced in width and has a series of openings 21. The apertures 21 serve to engage a pinion, while the longitudinal edges 22, 23 serve to guide in a housing, not shown, which supports the pinion. The lateral trimming, by which the longitudinal edges 22, 23 are produced, takes place in the region of the chamfers 10, 11. An uncut end region 24 follows it.

Aus der Fig. 1 ist erkennbar, dass das Maß 18 der verkürzten Breitseite 8 zwischen 50% und 70% bezogen auf die gegenüberliegende Breitseite 9 beträgt. Dadurch bleiben die Fasen flach und die Seitenkantenstärke 7 ist ausreichend groß dimensioniert.From the Fig. 1 It can be seen that the dimension 18 of the shortened broad side 8 is between 50% and 70% relative to the opposite broad side 9. As a result, the chamfers remain flat and the side edge thickness 7 is sufficiently large.

In der Zusammenschau mit den Fign. 2a und 2b ist erkennbar, dass die Verzahnung 3 so auf den Querschnitt des Halbzeugs abgestimmt ist, dass die verbleibende Breite 18 der verkürzten Breitseite 8 eine Abmessung hat, die zwischen dem maximalen Maß 26 der Verzahnung 3 an den der Zahnungsspitzen und dem geringsten Maß 27 im Zahnungsgrund 28 liegt. Dadurch bleibt im Bereich der Zahnung 3 eine über den Zahnungskopf 29 verlaufende Fase 11 bestehen. Dies ist von besonderem Vorteil, wenn das Verbindungsstück z.B. nach DE 2515542 C3 des zweiten Bauteils in Montagerichtung der Breitseite 8 liegt, da sich so über die verbleibende Fase 11 eine Fügeschräge bildet.In synopsis with the FIGS. 2a and 2b It can be seen that the toothing 3 is tuned to the cross section of the semifinished product, that the remaining width 18 of the shortened broad side 8 has a dimension between the maximum dimension 26 of the teeth 3 at the tooth tips and the smallest dimension 27 in the tooth bottom 28th lies. As a result, in the area of the toothing 3, a chamfer 11 extending over the toothing head 29 remains. This is of particular advantage if the connecting piece, for example DE 2515542 C3 of the second component in the mounting direction of the broad side 8 is because so forms a joining bevel over the remaining chamfer 11.

Im Vorstehenden wurde ausgeführt, welche Vorteile die Ausgestaltung hat, wenn dass das erste Bauteil eine Treibstange eines Treibstangenbeschlags ist. Es ist ersichtlich, dass die genannten Vorteile auch entstehen, wenn das erste Bauteil eine Stulpschiene eines Treibstangenbeschlags ist, und das zweite Bauteil eine Stulpschienenkopplung ist.In the foregoing, it has been explained what advantages the embodiment has when the first component is a drive rod of an espagnolette fitting. It can be seen that the stated advantages also arise when the first component is a faceplate of an espagnolette fitting, and the second component is a Stulpschienenkopplung.
