Description

Die Erfindung bezieht sich auf einen Treibstangenbeschlag für Fenster, Türen od. dgl. und betrifft insbesondere ein Einsteck-Kantengetriebe gemäß dem ersten Teils des Hauptanspruchs. Bei derartigen Beschlägen werden hinter einer die Beschlagnut abdeckenden Stulpschiene Treibstangen längsverschieblich geführt, auf denen z.B. Verriegelungszapfen od. dgl. befestigt sind, welche die Stulpschiene in Längsschlitzen durchdringen und mit zugehörigen Rahmenbauteilen eine Verriegelung bewirken können.The invention relates to a connecting rod fitting for windows, doors or the like. In particular, it relates to a plug-in edge gear according to the first part of the main claim. In such fittings, drive rods are guided longitudinally displaceably behind a faceplate covering the hardware groove, on which e.g. Locking pins or the like are attached, which penetrate the faceplate in longitudinal slots and can bring about locking with associated frame components.

Ortsfest ist an der Rückseite der Stulpschiene ein Gehäuse befestigt, in dem ein Drehantriebsglied - meistens in Form eines Ritzels - gelagert ist, dessen Zähne mit Durchbrüchen in der Treibstange zusammenarbeiten. Dabei wird die Drehbewegung eines Bedienungshandgriffs in eine Translationsbewegung einer Treibstange umgewandelt.Fixed on the back of the faceplate is a housing in which a rotary drive element - usually in the form of a pinion - is mounted, the teeth of which work together with openings in the drive rod. The rotary movement of an operating handle is converted into a translational movement of a drive rod.

In manchen Fällen ist es erwünscht, Einsteck-Kantengetriebe verfügbar zu haben, bei denen eine Translationsbewegung verschiedener Riegelglieder, z.B. am unteren und am oberen Ende eines Fenster- oder Türflügels, in zueinander entgegengesetzten Richtungen erfolgen. Zu diesem Zweck werden dann die Einsteck-Kantengetriebe mit Schubrichtungs-Umkehrgetrieben ausgestattet, welche zwei Treibstangen aufweisen, die sich durch die Handhebel-Betätigung in zueinander gegenläufige Bewegung versetzen lassen.In some cases it is desirable to have plug-in edge gears available in which a translational movement of different locking members, e.g. at the bottom and at the top of a window or door wing, in opposite directions. For this purpose, the plug-in edge gears are then equipped with thrust reversing gears, which have two drive rods, which can be set in opposite movement by the hand lever actuation.

Einsteck-Kantengetriebe der angegebenen Art sind beispielsweise durch die DE-C- 25 57 303 und die EP-A- 0 338 621 bekannt. Bei dem mit der DE-C 25 57 303 vorgeschlagenen Einsteck-Kantengetriebe mit Schubrichtungs-Umkehr wird die gegenläufige Bewegung zweier Treibstangen durch Benutzung zweier Ritzel erzielt, die eine zur Drehebene des eigentlichen Antriebsgliedes parallele Achslage haben, deren Drehachsen sich also parallel- zur- Hauptebene des Fenster- oder Türflügels erstrecken, in den das Einsteck-Kantengetriebe eingebaut ist. Hieraus ergibt sich die Notwendigkeit, jede der mit den beiden Ritzeln kämmenden Treibstangen zumindest abschnittweise um jeweils 90° zu ihrer normalen Einbauebene verdreht zu gestalten, damit sie in der Beschlagnut seitlich nebeneinander liegend mit den Ritzeln kämmen können. Diese Ausgestaltung der Treibstangen bedingt einen beträchtlichen Fertigungsaufwand und kann oft nur durch Anbringen von Zusatzteilen an den üblichen Treibstangen erhalten werden.Insert edge gears of the specified type are known, for example, from DE-C-25 57 303 and EP-A-0 338 621. The one with the DE-C 25 57 303 proposed plug-in edge gear with reversal of thrust direction, the opposite movement of two drive rods is achieved by using two pinions, which have an axis position parallel to the plane of rotation of the actual drive member, the axes of rotation of which are parallel to the main plane of the window or Extend door leaf, in which the plug-in edge gear is installed. This results in the need to make each of the drive rods meshing with the two pinions rotated at least in sections by 90 ° to their normal installation level so that they can mesh with the pinions lying side by side in the fitting groove. This design of the drive rods requires considerable manufacturing effort and can often only be obtained by attaching additional parts to the usual drive rods.

Mit der EP-A- 0 338 621 wird ein Einsteck-Kantengetriebe vorgeschlagen, bei dem die Umkehrritzel des Schubrichtungs-Umkehrgetriebes zu beiden Seiten des im Getriebegehäuse lagernden Antriebsgliedes angeordnet sind. Abgesehen davon, daß in diese Falle die Lagerstellen für die beiden Umkehrritzel jeweils nur halbschalenartig in jeder der beiden längsmitten-symmetrisch gestalteten Hälften des Getriebegehäuses ausgebildet sind und sich dadurch bei verminderter Lagerstabilität ein erhöhter Montageaufwand ergibt, ist es auch nachteilig, daß zur Erzielung der Schubrichtungsumkehr jeder der beiden Treibstangen über zwei Verzahnungen mit den beiden Umkehrritzeln in Eingriff steht und eine weitere Verzahnung an einer Treibstange für das Zusammenwirken mit dem Drehantriebsglied erforderlich ist. Es ergibt sich somit insgesamt eine sehr komplizierte Ausgestaltung des Einsteck-Kantengetriebes. Eine weitere Komplizierung resultiert daraus, daß die Verbindung der beiden Hälften des Getriebegehäuses mit der Stulpschiene über eine zusätzliche Riegelplatte vorgenommen werden muß, die bajonettverschlußartige Vorsprünge aufweist, welche mit komplementären Vorsprüngen an den Gehäusehälften in Wirkverbindung tritt, um eine Verriegelung des Getriebegehäuses an der Stulpschiene herbeizuführen. Die Vorsprünge der Gehäusehälften werden dabei in seitlichen Ausklinkungen der Stulpschienen aufgenommen.EP-A-0 338 621 proposes a plug-in edge gear in which the reversing pinions of the thrust reversing gear are arranged on both sides of the drive member mounted in the gear housing. Apart from the fact that in this case the bearing points for the two reversing pinions are each only half-shell-like in each of the two longitudinally symmetrical halves of the gear housing and this results in increased assembly effort with reduced storage stability, it is also disadvantageous that the thrust direction reversal is achieved in order to achieve this each of the two drive rods is in engagement with the two reversing pinions via two toothings and a further toothing on a drive rod is required for interaction with the rotary drive member. The overall result is a very complicated configuration of the plug-in edge gear. A further complication results from the fact that the connection of the two halves of the gear housing with the faceplate must be made via an additional locking plate which has bayonet-like projections which come into active connection with complementary projections on the housing halves in order to bring about a locking of the gear housing on the faceplate . The projections of the housing halves are received in the side notches of the faceplate.

Mit dem DE-U- 66 07 469 ist ein Einsteck-Kantengetriebe bekannt geworden, welches ein einstückig ausgebildetes, z.B. aus einem spanlos geformten Stanzteil bestehendes Getriebegehäuse aufweist. Die Befestigung desselben an der Stulpschiene wird dabei durch Verformen, z.B. Vernieten von Materialabschnitten bewirkt, die vom Getriebegehäuse absteht und angepaßte Durchbrüche der Stulpschiene durchdringen. In diesem Falle weist das Getriebegehäuse nur eine etwa halbkreisförmige Lagerung für die Bunde des als Antriebsglied dienenden Zahnrades auf, weil letzteres sich in das vorgeformte Gehäuse sonst nicht einsetzen läßt.With DE-U-66 07 469 a plug-in edge gear has become known, which is a one-piece, e.g. has a gear housing made of a non-cutting stamped part. The attachment of the same to the faceplate is done by deforming, e.g. Riveting of material sections causes that protrudes from the gear housing and penetrate adapted openings in the faceplate. In this case, the gear housing has only an approximately semicircular bearing for the collars of the gear serving as the drive member, because the latter cannot otherwise be inserted into the preformed housing.

Auch im DE-U- 78 11 092 ist ein Einsteck-Kantengetriebe als bekannt zu entnehmen, bei welchem zur Lagerung des Drehantriebsgliedes ein etwa bügelartig gestaltetes Gehäuse benutzt wird. Letzteres wird dabei zwischen von der Rückseite der Stulpschiene abstehende, zueinander parallele Stege gesetzt, welche einerseits der Längsführung der Treibstange dienen und andererseits segmentförmige Aussparungen haben, mit der sie einen Teilumfang der Bunde des Drehantriebsgliedes, insbesondere Antriebsritzels stützend aufnehmen. Die Verbindung des bügelartigen Gehäuses mit den Stegen der Stulpschiene bedarf eines zusätzlichen Arbeitsganges und erfordert demnach einen entsprechenden Mehraufwand.Also known from DE-U-78 11 092 is a plug-in edge gear, in which an approximately bow-shaped housing is used for mounting the rotary drive member. The latter is placed between mutually parallel webs projecting from the back of the faceplate, which on the one hand serve to guide the longitudinal rod of the drive rod and on the other hand have segment-shaped recesses with which they support a part of the circumference of the bundle of the rotary drive member, in particular drive pinion. The connection of the bow-like housing with the webs of the faceplate requires an additional operation and accordingly requires a corresponding additional effort.

Durch DE-U- 79 01 008 ist ein Stand der Technik für die Stoßstellenüberdeckung der einander zugewendeten Enden von Stulpschienen vorgegeben, die jeweils einander benachbart an einem Fenster- oder Türflügel einzubauenden Treibstangenbeschlägen angehören. Als Stoßstellenüberdeckung ist dabei eine auf der einen Stulpschiene befestigte, abgewinkelte Lasche aus federelastischem Material benutzt, die beim Eindrehen einer Befestigungsschraube durch die Stulpschiene entgegen der Federwirkung in ihre endgültige Lage niedergedrückt wird. Nachteilig ist hierbei, daß die aus Federmaterial bestehende Lasche durch einen separaten Arbeitsgang an der Stulpschiene befestigt werden muß. Gleiches gilt auch für die klappbeweglich auf der Stulpschiene gelagerte Arretierplatte gemäß EP-B- 0 006 439.DE-U-79 01 008 specifies a state of the art for the joint covering of the facing ends of faceplate rails, each of which is associated with connecting rod fittings to be installed adjacent to one another on a window or door leaf. An angled flap made of resilient material, which is fastened on one faceplate, is used as the joint covering, and is pressed into its final position against the spring action when a fastening screw is screwed in through the faceplate. The disadvantage here is that the tab made of spring material must be attached to the faceplate by a separate operation. The same also applies to the locking plate according to EP-B-0 006 439, which is movably mounted on the faceplate.

Ziel der Erfindung ist die Schaffung eines Einsteck-Kantengetriebes der eingangs genannten Art, das die vorgenannten Nachteile des Standes der Technik bei möglichst kostengünstiger Materialauswahl und einfacher Montage vermeidet. Es wird daher erfindungsgemäß ein Treibstangenbeschlag vorgeschlagen, welcher sich dadurch auszeichnet, daß das Gehäuse des Getriebes einteilig aus Kunststoff, insbesondere aus Kunststoff-Spritzguß, hergestellt ist, und daß auf die Stulpschiene mit Rückseitig abstehenden Distanzhaltern und mindestens einer einem Ende der Stulpschiene zugeordneten Arretierplatte für ein anschließendes Stulpschienenende einteilig aus Kunststoff, insbesondere durch Spritzgießen, gefertigt ist und daß dabei die Arretierplatte durch einen sogenannten Filmscharnier-Materialabschnitt mit der Stulpschiene in klappbeweglicher Verbindung gehalten ist.The aim of the invention is to provide a plug-in edge gear of the type mentioned, which avoids the aforementioned disadvantages of the prior art with the most cost-effective material selection and simple assembly. It is therefore proposed according to the invention a connecting rod fitting, which is characterized in that the housing of the transmission is made in one piece from plastic, in particular from plastic injection molding, and that on the faceplate with spacers projecting from the rear and at least one locking plate associated with one end of the faceplate for a subsequent faceplate end is made in one piece from plastic, in particular by injection molding, and that the locking plate is held in a hinged connection by a so-called film hinge material section with the faceplate.

Diese Ausbildung ergibt ein Einsteck-Kantengetriebe, bei dessen Herstellung aufwendigen Nietverfahren od. dgl. entfallen können. Statt dessen sind Schnapp-Rastverbindungen zwischen den Bau- und/oder Funktionsteilen möglich. Auch kann die gesamte Montage des Getriebes von einer Richtung her erfolgen, d.h., alle Teile werden von der gleichen Seite her zusammengelegt und die Stulpschiene wird dann als ein deckelartiger Abschluß benutzt. Rastausnehmungen sind dabei so in die Stulpschiene geformt, daß bei der Montage in diese eingeführte Rasthaken des Gehäuse-Formteils von der Innenkontur der Rastausnehmung in ihre endgültige Rastlage geführt werden, aus der sie dann nicht mehr ohne Beschädigung der Stulpschiene oder der Rasthaken entfernt werden können.This design results in a plug-in edge gear, in the production of which complex riveting processes or the like can be omitted. Instead, snap-snap connections between the components and / or functional parts are possible. The entire assembly of the gear unit can also be done in one direction, i.e. all parts are put together from the same side and the faceplate is then used as a cover-like closure. Snap-in recesses are shaped in the faceplate so that when they are inserted into the snap-in hook of the housing molded part, they are guided from the inner contour of the snap-in recess into their final snap-in position, from which they can then no longer be removed without damaging the faceplate or the snap-in hook.

Nach einem anderen Ausgestaltungsmerkmal weist das Getriebegehäuse parallel zur Lagerachse des als Antriebsglied dienenden Ritzels gerichtete Bohrungen zur Aufnahme von Befestigungsschrauben für die Lagerrosette eines Ritzel-Bedienungshandhebels auf, die einen eckigen, insbesondere sechseckigen Querschnitt haben. Das beim Einschneiden des Gewindes durch selbstschneidende Schrauben verdrängte Material kann als Folge dieser Ausbildung in die außerhalb des Schraubendurchmessers liegenden Mehrkant-Bereiche ausweichen.According to another design feature, the gear housing has bores directed parallel to the bearing axis of the pinion serving as the drive member for receiving fastening screws for the bearing rosette of a pinion operating lever which have an angular, in particular hexagonal, cross section. The material displaced by self-tapping screws when cutting the thread can result as a result Avoid training in the polygon areas outside the screw diameter.

Bei manchen Anwendungsfällen, nämlich dann, wenn das Treibstangen-Kantengetriebe nur mit zwei Schaltstellungen für die Treibstangen arbeitet, kommt das als Drehantriebsglied benutzte Ritzel mit einem sich nur über einen Winkelbogen von 90° erstreckenden Verzahnung aus. In einem solchen Falle ist es dann möglich, daß Getriebegehäuse in seinem hinteren, kreisbogenförmigen Abschnitt geschlossen zu halten, also mit einer relativ dicken Wand zu versehen und dadurch eine beträchtliche Festigkeitssteigerung des Gehäuses zu erreichen.In some applications, namely when the drive rod edge gear works only with two switch positions for the drive rods, the pinion used as the rotary drive member manages with a toothing which only extends over an angular arc of 90 °. In such a case, it is then possible to keep the transmission housing closed in its rear, arcuate section, that is to say to provide it with a relatively thick wall, and thereby to achieve a considerable increase in the strength of the housing.

Wird ein Einsteck-Kantengetriebe mit einer Schubrichtungs-Umkehrvorrichtung ausgestattet, dann ist es von großem Vorteil, wenn die Umkehrritzel durch in das Gehäuse eingebrachte Ausnehmungen ortsfest, aber drehbar gehalten werden. Die Stulpschiene kann dann an ihrer Rückseite auch Vorsprünge aufweisen, welche so geformt sind, daß sie zusammen mit den Ausnehmungen im Getriebegehäuse eine je aus zwei Lagerschalen bestehende kreisrunde Lagerung bilden.If a plug-in edge gear is equipped with a thrust reversing device, it is of great advantage if the reversing pinions are held in a stationary but rotatable manner by means of recesses made in the housing. The faceplate can then also have projections on its rear side, which are shaped such that they form a circular bearing each consisting of two bearing shells together with the recesses in the gear housing.

Werden bei Ausstattung des Einsteck-Kantengetriebes mit einer Schubrichtungsumkehr-Vorrichtung zur Bewegungsumkehr zwei Ritzel nebeneinander in gleicher Achsrichtung vorgesehen und auch achsparallel zum Drehantriebsglied angeordnet, dann lassen sich die baulichen Abmessungen, vornehmlich die Baulänge des Einsteck-Kantengetriebes auf ein Minium reduzieren. Durch diese Anordnung ist es auch nicht nötig, die mit den Umkehrritzeln kämmenden Treibstangenabschnitte um 90° zur normalen Ausrichtung der Treibstangenebene verdreht anzuordnen. Dies ist nicht nur von Vorteil für den Bau der zur Teilefertigung dienenden Werkzeuge. Vielmehr können auch ggf. benötigte Zusatzteile zur Bildung der mit den Umkehrritzeln kämmenden Treibstangenbereiche wegfallen. Eine einfache Herstellung der Treibstangen als Stanzbiegeteile ist möglich.If two pinions are provided next to each other in the same axis direction when the plug-in edge gear is equipped with a thrust reversing device for reversing motion and are also arranged axially parallel to the rotary drive element, then the structural dimensions, primarily the overall length of the plug-in edge gear, can be reduced to a minimum. With this arrangement, it is also not necessary to arrange the drive rod sections meshing with the reversing pinions rotated by 90 ° to the normal alignment of the drive rod plane. This is not only advantageous for the construction of the tools used to manufacture parts. Rather, any additional parts required to form the drive rod areas which mesh with the reversing pinions can also be omitted. A simple manufacture of the drive rods as stamped and bent parts is possible.

Nach der Erfindung liegt ein Vorteil auch darin, daß die Einheit von Stulpschiene, Arretierplatte und Distanzhalter - durch Spritzgießen - in einem Arbeitsgang hergestellt werden kann. Bei einer verwandten Bauform ist es möglich, daß betreffende Formteil auch durch Umspritzen eines in die Spritzgußform zuvor eingelegten Kernbauteils, insbesondere Metallbauteils, zu erzeugen. Eine Stulpschiene aus Kunststoff kann auf diese Art und Weise beispielsweise auch mit einer Arretierplatte aus Metall vereinigt werden.According to the invention, there is also an advantage in that the unit of faceplate, locking plate and spacer can be produced in one operation - by injection molding. In a related design, it is possible to produce the molded part in question by overmolding a core component, in particular a metal component, previously inserted into the injection mold. A faceplate made of plastic can also be combined in this way, for example, with a locking plate made of metal.

Nach einem weiteren Ausgestaltungsmerkmal der Erfindung weist das Getriebegehäuse an parallelen Wänden jeweils paarweise einander zugeordnete Rasthaken auf. Dadurch wird gewährleistet, daß die Rasthaken das Gehäuse verwindungsfrei mit der Stulpschiene in Verbindung halten. Die Rastkanten der Rasthaken weisen dabei bevorzugt nach außen. Hierdurch wird nämlich erreicht, daß bei einer ungleichmäßigen Belastung des als Drehantriebsglied dienenden Zahnrades eine Kippbewegung desselben und eine daraus resultierende Kraftkomponente, welche das Gehäuse auseinander zu drücken sucht, selbsthelfend genutzt ist, um das Getriebegehäuse an der Stulpschiene zu halten.According to a further feature of the invention, the gear housing has latching hooks which are assigned to one another in pairs on parallel walls. This ensures that the locking hooks hold the housing in connection with the faceplate without twisting. The locking edges of the locking hooks preferably point outwards. In this way it is achieved that, in the event of an uneven load on the gear serving as the rotary drive member, a tilting movement of the same and a resultant force component, which tries to push the housing apart, is used to help hold the gear housing on the faceplate.

Auch ist es von besonderem Vorteil, wenn die aus den Umkehrritzeln resultierenden Aushebekräfte von zwischen diesen liegenden Rasthaken aufgenommen werden können. Dies ist vor allem dann wichtig, wenn die Zahnung der Ritzel und der damit kämmenden Zahnstangen nur eine geringe Höhe aufweisen und deshalb schon ein minimales Ausheben der Zahnung zu einer Fehlfunktion führen könnte.It is also particularly advantageous if the lifting forces resulting from the reversing pinions can be absorbed by latching hooks located between them. This is particularly important if the teeth of the pinions and the toothed racks meshing with them are only a small height and therefore a minimal lifting of the teeth could lead to a malfunction.

Als besonders vorteilhaft für die Haltbarkeit des Einsteck-Kantengetriebes hat sich auch eine Herstellung des Getriebegehäuses aus einem Kunststoff erwiesen, welcher einen Gleitmittelzusatz enthält. Solche Kunststoffe weisen nicht nur eine hohe Oberflächenhärte auf, sondern zeichnen sich auch durch ein gutes Verschleißverhalten aus. Beispielsweise können Polyoximethylene und Polyamide für diesen Zweck benutzt werden.It has also proven to be particularly advantageous for the durability of the plug-in edge transmission to produce the transmission housing from a plastic which contains a lubricant additive. Such plastics not only have a high surface hardness, but are also characterized by good wear behavior. For example, polyoximethylenes and polyamides can be used for this purpose.

Nach einem weiteren Ausführungsvorschlag weisen die Distanzhalter an ihren Längskanten Rastvorsprünge auf, welche zusammen mit den Körper des Distanzhalters ein Langloch einer Treibstange durchdringen und dann hinter derselben verrasten. Die notwendige Elastizität für einen derartigen Rastvorgang wird dabei durch die Materialeigenschaften und die geringen Wandstärken erzielt, die sich im Bereich der Durchgangsbohrung für die Befestigungsschrauben ergeben. Bevorzugt kann der Durchmesser diese Durchgangsbohrung so gewählt werden, daß eine evtl. nach innen eingefallene Wand des Distanzhalters beim Einbringen der Befestigungsschraube in ihre Ursprungslage nach außen zurückversetzt wird.According to a further embodiment, the spacers have locking projections on their longitudinal edges, which, together with the body of the spacer, penetrate an elongated hole in a drive rod and then lock behind it. The necessary elasticity for such a locking process is achieved by the material properties and the small wall thicknesses that result in the area of the through hole for the fastening screws. The diameter of this through-hole can preferably be selected such that any wall of the spacer that has collapsed inward is set back outward when the fastening screw is inserted into its original position.

In Fig. 1 ist ein Einsteck-Kantengetriebe 1 zu sehen, das ein Getriebegehäuse 2, ein Antriebsritzel 3 sowie eine Stulpschiene 4 aufweist.In Fig. 1, a plug-in edge gear 1 can be seen, which has a gear housing 2, a drive pinion 3 and a faceplate 4.

Auf das Antriebsritzel 3 wird die Drehbewegung eines - nicht dargestellten - Bedienungs-Handhebels über einen - ebenfalls nicht gezeigten - Vierkantdorn übertragen. Die Rotation des Antriebsritzels 3 wird dann in eine Translationsbewegung einer Treibstange 5 umgewandelt, welche im Getriebegehäuse 2 und an der Stulpschiene 4 geführt ist. An der Treibstange 5 ist dabei zumindest ein Verriegelungszapfen 6 befestigt, welcher im Zusammenwirken mit einem an einem Rahmen befestigten Bauteil für die Verriegelung eines Fenster- oder Türflügels in seiner Schließlage sorgt.On the drive pinion 3, the rotary movement of a - not shown - operating hand lever is transmitted via a - also not shown - square mandrel. The rotation of the drive pinion 3 is then converted into a translational movement of a drive rod 5, which is guided in the gear housing 2 and on the faceplate 4. At least one locking pin 6 is attached to the drive rod 5, which in cooperation with a component attached to a frame ensures the locking of a window or door leaf in its closed position.

Im Getriebegehäuse 2 und an der Stulpschiene 4 führt sich beim Ausführungsbeispiel nach Fig. 1 noch eine weitere Treibstange 9, die eine zur Treibstange 5 entgegengesetzte Schubrichtung erhalten soll. Für die Erzeugung einer zueinander entgegengesetzten Schubrichtung für die beiden Treibstangen 5 und 9 sind zwei nebeneinander angeordnete Ritzel vorgesehen, die mit den jeweils gezahnten Enden 8 der Treibstangen 5 und 9 kämmen, welche dem Mittelpunkt der Umkehrritzel 7 diametral gegenüberliegend angeordnet sind.In the exemplary embodiment according to FIG. 1, a further drive rod 9 leads in the gear housing 2 and on the faceplate 4 and is intended to receive a thrust direction opposite to the drive rod 5. For the generation of an opposite direction of thrust for the two drive rods 5 and 9, two adjacent pinions are provided which mesh with the toothed ends 8 of the drive rods 5 and 9, which are arranged diametrically opposite the center of the reversing pinion 7.

Die Verbindung des Getriebegehäuses 3 mit der Stulpschiene 4 ist über Rasthaken 10 hergestellt, die entsprechende Ausnehmungen 11 der Stulpschiene 4 durchdringen und dann an deren Außenseite einrasten.The connection of the gear housing 3 with the faceplate 4 is made via locking hooks 10, which penetrate the corresponding recesses 11 of the faceplate 4 and then snap into place on the outside thereof.

Die Stulpschiene 4 ist einteilig ausgeführt und trägt dabei rückseitig abstehende Distanzhalter 12 zur Abstützung am Grund einer im Flügelprofil vorgesehenen Beschlagnut. Zumindest im Bereich jedes Distanzhalters 12 werden auch - nicht dargestellte - Befestigungsschrauben für das Einsteck-Kantengetriebe 1 in Bohrungen aufgenommen.The faceplate 4 is made in one piece and carries spacers 12 protruding from the rear for support on the base of a fitting groove provided in the sash profile. At least in the area of each spacer 12, fastening screws (not shown) for the plug-in edge gear 1 are also received in bores.

Bei einer bevorzugten Ausführungsform eines Einsteck-Kantengetriebes 1 ist die Stulpschiene 4 auch einstückig mit Arretierplatten 14 ausgebildet und dabei durch einen Abschnitt 15 hiermit verbunden, welcher einen wesentlich geringeren Querschnitt als die Stulpschiene 4 und die Arretierplatte 14 aufweist. Durch die Auswahl des Materials und des Querschnitts für den Abschnitt 15 wird erreicht, daß dieser als sogenanntes Filmscharnier genutzt werden kann. Jede Arretierplatte 14 wird mit Hilfe des Filmscharnier-Abschnitts 15 zum Zwecke der Montage eines - nicht dargestellten - angrenzenden Beschlag-Bauteils zunächst in eine Lage hochgestellt, wie sie in Fig. 1 strichpunktiert angedeutet ist. Anschließend wird die Arretierplatte 14 dann nach unten gedrückt, um die Stoßstelle zwischen benachbarten Beschlags-Bauteilen an der Vorderseite zu überbrücken. Sie verhindert damit ein Anheben oder Ausbiegen der Nachbarbauteile.In a preferred embodiment of a plug-in edge gear 1, the faceplate 4 is also formed in one piece with locking plates 14 and is connected to it by a section 15 which has a substantially smaller cross section than the faceplate 4 and the locking plate 14. The selection of the material and the cross section for the section 15 ensures that it is a so-called film hinge can be used. Each locking plate 14 is first raised into a position with the aid of the film hinge section 15 for the purpose of mounting an adjacent fitting component (not shown), as is indicated by dash-dotted lines in FIG. 1. Then the locking plate 14 is then pressed down to bridge the joint between adjacent fitting components on the front. This prevents the neighboring components from being lifted or bent out.

Auch jede Arretierplatte 14 weist an ihrer Unterseite ebenfalls einen Distanzhalter 16 auf, welcher mit einer Bohrung 17 zur Aufnahme einer nicht eingezeichneten Befestigungsschraube versehen ist. Weiterhin ist jede Arretierplatte 14 auch noch mit einem Senkloch 17a zur Aufnahme einer Befestigungsschraube versehen, und zwar so, daß diese auch das angrenzende Beschlags-Bauteil zweckmäßigerweise durchdringen kann und mit diesem eine Verkettung herstellt.Each locking plate 14 also has a spacer 16 on its underside, which is provided with a bore 17 for receiving a fastening screw (not shown). Furthermore, each locking plate 14 is also provided with a countersunk hole 17a for receiving a fastening screw, in such a way that it can expediently penetrate the adjacent fitting component and create a linkage with it.

In den Fig. 2 und 3 ist ein Abschnitt des Einsteck-Kantengetriebes 1 in vergrößertem Maßstab dargestellt. Dabei sind besonders die mehrkantigen Durchlässe 18 zu sehen, in welche selbstschneidende Befestigungsschrauben eingedreht werden können, welche die Lagerrosette eines - nicht eingezeichneten - Handhebels mit dem Getriebegehäuse verbinden.2 and 3, a section of the plug-in edge gear 1 is shown on an enlarged scale. In particular, the polygonal passages 18 can be seen, into which self-tapping fastening screws can be screwed, which connect the bearing rosette of a hand lever (not shown) to the gear housing.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel eines Einsteck-Kantengetriebes 1 ist der Drehwinkel für das als Antriebsritzel 3 ausgeführte Drehantriebsglied und folglich auch der Drehwinkel für den Handhebel auf 90° beschränkt. Deshalb kann hier der kreissegmentförmige Abschnitt des Getriebegehäuses 2 mit einer Rückwand 19 versehen werden, welche die Gesamtstabilität erhöht und dem unverzahnten Umfangsabschnitt des Antriebsritzels 3 ein zusätzliches Widerlager bietet.In the exemplary embodiment of a plug-in edge gear 1 shown in FIG. 2, the angle of rotation for the rotary drive element designed as drive pinion 3 and consequently also the angle of rotation for the hand lever are limited to 90 °. For this reason, the section of the gearbox housing 2 in the form of a segment of a circle can be provided with a rear wall 19, which increases the overall stability and offers the toothless peripheral section of the drive pinion 3 an additional abutment.

Wird das Einsteck-Kantengetriebe 1 jedoch mit einem für eine Handhebel-Bewegung von 180° ausgelegten Antriebsritzel 3 ausgestattet, dann muß die Rückwand 19 entfallen. In diesem Falle wird die Lagerung des Antriebsritzels 3 ausschließlich über dessen seitliche Bunde 20 erreicht, die in entsprechende Ausnehmungen der Seitenwände des Getriebegehäuses 2 eingreifen.However, if the plug-in edge gear 1 is equipped with a drive pinion 3 designed for a hand lever movement of 180 °, then the Rear wall 19 is eliminated. In this case, the drive pinion 3 is only supported via its side collars 20 which engage in corresponding recesses in the side walls of the transmission housing 2.

Fig. 3 zeigt noch als Besonderheit die Lagerung der beiden Umkehrritzel 7 im Getriebegehäuse 2 und an der Rückseite der damit verbundenen Stulpschiene 4.3 shows, as a special feature, the mounting of the two reversing pinions 7 in the transmission housing 2 and on the rear side of the faceplate 4 connected thereto.

Von der Rückseite der Stulpschiene 4 stehen Vorsprünge 21 ab, die an ihren freien Enden kreisbogenförmige Lagerschalen haben. Hierin können sich die Umkehrritzel 7 jeweils mit ihren Lagerzapfen abstützen. Diesen Vorsprüngen 21 zugeordnet sind in den Seitenwandungen des Getriebegehäuses 2 Ausnehmungen 22, welche halbkreisförmige Lagerschalen bilden, die den Lagermulden in den Endflächen der Vorsprünge 21 gegenüberliegen. Miteinander wirken die Vorsprünge 21 und die Ausnehmungen 22 jeweils als Drehlagerung für die Zapfen der Umkehrritzel 7 zusammen.From the back of the faceplate 4 protrusions 21 protrude, which have arcuate bearing shells at their free ends. The reversing pinions 7 can each be supported here with their bearing journals. Associated with these projections 21 are recesses 22 in the side walls of the gear housing 2, which form semicircular bearing shells, which lie opposite the bearing recesses in the end faces of the projections 21. The projections 21 and the recesses 22 each work together as a rotary bearing for the pins of the reversing pinion 7.

Eine vorteilhafte Ausgestaltung für das Einsteck-Kantengetriebe 1 wird dadurch erreicht, daß die das Getriebegehäuse 2 mit der Stulpschiene 4 verbindenden Rasthaken 10 eine über die Länge des Getriebegehäuses 2 hinweg verteilte Anordnung haben (Fig. 3) und dabei jeweils paarweise an den voneinander abgewendeten Gehäuseseiten ausgebildet sind (Fig. 4). Ein Paar solcher Rasthaken 10 ist dabei auch zwischen den Lagerstellen beider Umkehrritzel 7 vorgesehen, damit die dort auftretenden Aushebekräfte sicher zwischen dem Getriebegehäuse 2 der Stulpschiene 4 aufgenommen werden können.An advantageous embodiment for the plug-in edge gear 1 is achieved in that the locking hooks 10 connecting the gear housing 2 to the faceplate 4 have an arrangement distributed over the length of the gear housing 2 (FIG. 3) and in each case in pairs on the sides of the housing facing away from one another are formed (Fig. 4). A pair of such locking hooks 10 is also provided between the bearing points of both reversing pinions 7 so that the lifting forces occurring there can be safely absorbed between the gear housing 2 of the faceplate 4.

Besonders aus Fig. 1 der Zeichnung ist ersichtlich, daß die beiden Treibstangen 5 und 9 des Einsteck-Kantengetriebes 1 lediglich Verkröpfungen aufweisen müssen, die quer zur Treibstangenebene gerichtet sind. Die Treibstangen 5 und 9 lassen sich daher leicht als Stanzbiegeteile herstellen.In particular, from Fig. 1 of the drawing it can be seen that the two drive rods 5 and 9 of the plug-in edge gear 1 only have to have crankings which are directed transversely to the drive rod plane. The drive rods 5 and 9 can therefore be easily manufactured as stamped and bent parts.

In Fig. 4 ist die Verbindung des Getriebegehäuses 2 mit der Stulpschiene 4 dargestellt. Dabei wird deutlich, daß die an das Getriebegehäuse 2 einstückig angeformten Rasthaken 10 die Rastausnehmungen 11 der Stulpschiene 4 durchdringen. Jeder Rasthaken 10 ist mit nach außen vorspringenden Rastkanten 23 versehen, die einen Rasteingriff 28 hinterfassen, welcher an der Außenseite der Stulpschiene 4 in deren Rastausnehmungen 11 liegt. Beim Aufdrücken des Getriebegehäuses 2 auf die Stulpschiene 4 zum Zwecke der Montage werden die Rasthaken 10 zunächst durch einen ihren Rastkanten 23 voreilende Schrägfläche 24 elastisch nach einwärts in eine Ausnehmung 25 verlagert, die sich in der Seitenflächen eines Stützsteges 29 für die Treibstange 5 befindet. Beim weiteren Eindringen der Rasthaken 10 in die Rastausnehmungen 11 treffen dann die Rasthaken 10 mit den ihrem freien Ende zugeordneten Innenkanten auf Schrägflächen 30, welche sich zur Außenseite der Stulpschiene 4 hin an die Ausnehmung 25 im Stützsteg 29 anschließen. Hierdurch wird dann jedem Rasthaken 10 eine auswärts gerichtete Spreizbewegung aufgezwungen, so daß seine auswärts gerichtete Rastkante 23 den Rasteingriff 28 der Rastausnehmung 11 in der Stulpschiene 4 formschlüssig hinterfaßt. Die Kontur der Ausnehmung 25 mit der Schrägfläche 30 ist dabei so gewählt, daß nur elastische Verformungen der Rasthaken 10 und der Stulpschiene 4 zur Herstellung der Rastverbindung möglich sind, daß aber ein Lösen dieser Rastverbindung ohne Beschädigung der Stulpschiene 4 oder des Getriebegehäuses 2 verhindert ist.4, the connection of the gear housing 2 with the faceplate 4 is shown. It is clear that the locking hooks 10 integrally formed on the gear housing 2 penetrate the locking recesses 11 of the faceplate 4. Each latching hook 10 is provided with latching edges 23 projecting outwards, which engage a latching engagement 28 which lies on the outside of the faceplate 4 in its latching recesses 11. When the gear housing 2 is pressed onto the faceplate 4 for the purpose of assembly, the latching hooks 10 are first displaced elastically inward by an inclined surface 24 leading their latching edges 23 into a recess 25 which is located in the side surfaces of a support web 29 for the drive rod 5. When the latching hooks 10 penetrate further into the latching recesses 11, the latching hooks 10, with their inner edges assigned to their free end, meet inclined surfaces 30, which adjoin the recess 25 in the support web 29 towards the outside of the faceplate 4. As a result, an outward spreading movement is then forced onto each latching hook 10, so that its outwardly directed latching edge 23 positively engages behind the latching engagement 28 of the latching recess 11 in the faceplate 4. The contour of the recess 25 with the inclined surface 30 is selected so that only elastic deformations of the latching hook 10 and the faceplate 4 are possible for producing the latching connection, but that a loosening of this latching connection is prevented without damaging the faceplate 4 or the gear housing 2.

Fig. 5 zeigt einen Querschnitt durch den Distanzhalter 12 mit der Bohrung 17a. Dabei ist zu erkennen, daß der Distanzhalter 12 die Treibstange 9 in einem dafür vorgesehenen Langloch 26 durchgreift. An dem Distanzhalter 12 sind seitliche Rastnasen 31 angebracht, deren größtes Außenmaß 32 größer ist als das lichte Maß 33 des Langlochs 26 der Treibstange 9.Fig. 5 shows a cross section through the spacer 12 with the bore 17a. It can be seen that the spacer 12 extends through the drive rod 9 in a slot 26 provided for this purpose. Lateral locking lugs 31 are attached to the spacer 12, the largest outside dimension 32 of which is larger than the inside dimension 33 of the elongated hole 26 of the drive rod 9.

Die Rastnasen 31 sind an ihrer unteren Seite mit einer Schrägen 34 ausgestattet, die das Einclipsen der Treibstange 9 erleichtern. An ihrem oberen Ende weisen die Rastnasen 31 einen nahezu waagerechten Abschnitt 35 auf, dessen Abstand zur Treibstangen-Unterkante 36 so gewählt ist, daß die Treibstange 9 ausreichend Raum für ihre Bewegung hat.The locking lugs 31 are provided on their lower side with a bevel 34, which make it easier to clip in the drive rod 9. At their upper end, the latching lugs 31 have an almost horizontal section 35, the distance to the lower edge 36 of the connecting rod is selected so that the connecting rod 9 has sufficient space for its movement.

Der Bohrungsdurchmesser 27 ist so gewählt, daß die Befestigungsschraube 37 eine evtl. vorhandene plastische Verformung ausgleicht, indem sie sich mit ihrer Außenkontur 38 nahe an den Innendurchmesser 39 der Bohrung 17a anlegt. Dadurch ist ein Abgleiten der Treibstange 9 bei montierter Befestigungsschraube 37 unmöglich.The bore diameter 27 is selected such that the fastening screw 37 compensates for any plastic deformation that may be present, in that its outer contour 38 bears close to the inner diameter 39 of the bore 17a. This makes it impossible for the drive rod 9 to slide when the fastening screw 37 is installed.
