Abstract

A catch device is disclosed for joining a window pane (1c) to a window lifter by means of at least one pair of elastically spreadable cheeks (31, 32). One of the cheeks (32) has at least one snap-on element (30) oriented towards the window pane (1c) and shaped as a hook, pin or the like associated to a hole (10) in the window pane (1c). An inserter spreads the cheeks (31, 32) when inserting the window pane (1c) into the snap-on device. In the locked state of the window pane (1c), the circumference of the snap-on element (30) fills the hole (10) in the window pane (1c) over at least part of the width of the snap-on element (30).

Description

Vorrichtung zum Verbinden einer Fensterscheibe mit einem Device for connecting a window to a
FensterheberWindow regulator
Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zum Verbinden einer Fensterscheibe mit einem Fensterheber gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for connecting a window pane to a window regulator according to the preamble of claim 1.
Aus der EP 0 208 237 Bl ist ein Tragelement zur Verbindung der Fensterscheibe mit einer entsprechenden Führungsvorrich¬ tung bekannt, die mehrere, beiderseits der Unterkante der Fensterscheibe angeordnete Stützflügel aufweist. Einer der Stützflügel trägt einen Stift, dem ein Loch in der Fenster¬ scheibe zugeordnet ist. Beim Einführen der Fensterscheibe zwischen die elastischen Stützflügel biegen sich diese nach außen, bis der Stift m das Scheibenloch eingerastet ist. Um die Fensterscheibe zwischen die beiden Stützflügel einführen zu können, ist die Oberseite des Stiftes als Einführungsschräge ausgebildet. Nachteilig ist jedoch das damit verbunden große Spiel zwischen dem Stift und dem Scheibenloch. So treten bei Umkehr der Belastungsrichtung (Bewegungsrichtung der Fensterscheibe) oft sogenannte Umschaltgeräusche auf . Außerdem neigt die Vorrichtung bei höherer Belastung, insbesondere bei einem zusätzlichen Verkanten der Fensterscheibe, zum Ausrasten aus dem Schei¬ benloch, wodurch der Fensterheber unbrauchbar wird.From EP 0 208 237 B1 a support element for connecting the window pane to a corresponding guide device is known, which has a plurality of support wings arranged on both sides of the lower edge of the window pane. One of the support wings carrying a pin which is associated with a hole in the window ¬ disc. When the window pane is inserted between the elastic support wings, these bend outwards until the pin m engages the window hole. In order to be able to insert the window pane between the two support wings, the top of the pin is designed as an insertion bevel. However, the associated great play between the pin and the disk hole is disadvantageous. So when switching the load direction (direction of movement of the window pane) so-called switching noises often occur. In addition, the device tends to disengage from the window hole under higher loads, in particular when the window pane is additionally tilted, as a result of which the window lifter becomes unusable.
Eine weitere schnappbare Kupplungsvorrichtung zwischen Scheibe und Scheibenheber zeigt die DE 31 08 244 AI. Sie besteht aus zwei miteinander verbundenen kanalartigen Profilen, von denen das eine einen Bereich der Scheibenun- terkante umschließt und dort befestigt ist. Das andere nach unten offene Profil trägt an seinen Enden nach innen gerich¬ tete Haken, die mit Vorsprüngen von Winkelelementen der Hebevorrichtung in Eingriff treten können, wodurch eine formschlüssige Verbindung erreichbar ist. Gemäß dem Vor¬ schlag soll das Einschnappen der Verbindungselemente durch das Verfahren der Fensterscheibe gegen die obere Anschlags- Position erzwungen werden, wodurch gleichzeitig ein selbst¬ tätiges Ausrichten der Scheibe in der Rahmenkonstruktion erfolgt und zusätzliche Handgriffe während der Montage nicht notwendig sind.Another snap-on coupling device between the window and the window lifter is shown in DE 31 08 244 AI. It consists of two interconnected channel-like profiles, one of which encloses an area of the lower edge of the pane and is fastened there. The other profile, which is open at the bottom, has inward-facing hooks at its ends which can engage with projections of angular elements of the lifting device, as a result of which a positive connection can be achieved. According to the proposal, the snap-in of the connecting elements should be forced by moving the window pane against the upper stop position, which means that the pane is automatically aligned in the frame construction and additional manipulations are not necessary during assembly.
Da jedoch das profilartige Kupplungselement an der Schei- benunterkante vormontiert werden muß, führt der damit verbundene Dickenaufbau regelmäßig zu einer erschwerten Einführung der Fensterscheibe in den Türschach . Wegen der notwendigerweise fehlenden Dichtungen in diesem Bereich kommt es deshalb während der Montage immer wieder zu Beschä¬ digungen des Lackes. Ein weiteres Problem können die im Schnappbereich der Kupplungselemente erforderlichen minima¬ len Toleranzen darstellen, um Umschaltgeräuschen beim Betrieb des Fensterhebers vorzubeugen.However, since the profile-like coupling element has to be preassembled on the lower edge of the pane, the thickness build-up associated therewith regularly leads to a difficult insertion of the window pane into the door chess. Because of the necessarily missing seals in this area That is why the paint is repeatedly damaged during assembly. A further problem can be the minimum tolerances required in the snap area of the coupling elements in order to prevent switching noises when the window regulator is in operation.
Eine weitere Ausführungsform einer schnappbaren Scheibenbe¬ festigung offenbart die Druckschrift JP 6-135228. Die an der Unterkante der Fensterscheibe befestigten Elemente besitzen an ihren freien Enden konische, widerhakenförmige Bereiche, denen U-profilartige Verbindungselemente des Fensterhebers zugeordnet sind. Sie weisen außerdem Einfüh¬ rungsschrägen auf, mit denen die konischen Bereiche der an der Fensterscheibe befestigten Elemente in Eingriff treten können. Beim Zusammenführen der Verbindungselemente werden die Schenkel der U-Profile elastisch gespreizt. Nach Ab¬ schluß der Montage (in der eingeschnappten Position) über¬ greifen an den freien Enden der U-Profile vorgesehene, nach innen gerichtete Haken die Vorsprünge der konischen, wider¬ hakenförmigen Bereiche der anderen Elemente. Von Nachteil ist jedoch, daß der von der Scheibenkante abkragende Teil des an der Fensterscheibe befestigten Verbindungselements den theoretisch ausführbaren Hub verkürzt.A further embodiment of a snap-on pane fastening is disclosed in JP 6-135228. The elements fastened to the lower edge of the window pane have conical, barb-shaped areas at their free ends, to which U-profile-like connecting elements of the window lifter are assigned. They also have insertion bevels with which the conical regions of the elements fastened to the window pane can engage. When the connecting elements are brought together, the legs of the U-profiles are elastically spread. After completion of the assembly (in the snapped-in position), inward hooks provided on the free ends of the U-profiles overlap the projections of the conical, barbed regions of the other elements. A disadvantage, however, is that the part of the connecting element fastened to the window pane that projects from the edge of the window shortens the theoretically feasible stroke.
Die bekannten schnappbaren Verbindungen zwischen einer Fen¬ sterscheibe und dem Mitnehmer eines Fensterhebers verwenden in ein Scheibenloch einrastbare Schnappelemente, deren obere Begrenzungsflächen als Einführungsfasen für die Schei- benunterkante schräglaufend ausgebildet sind. Aufgrund dessen, ergibt sich zwischen dem in das Scheibenloch einge¬ rasteten Schnappelement und der Lochkontur zwangsläufig ein Sitz mit viel Spiel, was beim Wechsel der an den Mitnehmer angreifenden Kraf richtung zu Umschaltgeräuschen führt. Dar- überhmaus kann das große Spiel bei Belastungszuständen, die mit einem Verkanten der Fensterscheibe im Mitnehmer ein¬ hergehen, zum Lösen der Verbindung führen.The known snap connections between a window pane and the driver of a window lifter use snap elements which can be snapped into a window hole, the upper boundary surfaces of which are designed as inclined chamfers for the lower edge of the window. Because of this, there is inevitably a seat with a lot of play between the snap element which is latched into the disk hole and the hole contour, which is the case when changing the driver attacking force direction leads to switching noises. Above all, the large play under load conditions, which go hand in hand with a tilting of the window pane, can lead to the loosening of the connection.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Verbinden einer Fensterscheibe mit einem Fensterheber zu entwickeln, die sich durch einen konstruktiv einfachen Aufbau und einfache Herstellbarkeit sowie Montagefreundlich¬ keit auszeichnet . Dabei soll die Fensterscheibe vor ihrer Einführung in den Türschacht keinerlei Zusatzteile tragen, zumindest nicht solche, die zu einem wesentlichen Dickenauf¬ bau der Fensterscheibe führen. Darüber hinaus soll ein weitestgehend spielfreier Sitz der Fensterscheibe im Mitneh¬ mer des Fensterhebers gewährleistet sein, ohne daß dadurch die Herstellung der schnappbaren Verbindung erschwert wird.The invention has for its object to develop a device for connecting a window to a window lifter, which is characterized by a structurally simple structure and ease of manufacture and assembly friendliness. Before being introduced into the door shaft, the window pane should not carry any additional parts, at least not those that lead to a substantial increase in the thickness of the window pane. In addition, a largely backlash-free fit of the window pane in the driver of the window lifter should be ensured without making the snap connection difficult.
Erfindungsgemäß wird die Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.According to the invention the object is achieved by the characterizing features of patent claim 1.
Die Erfindung geht von der Erkenntnis aus, daß das Schnapp¬ element des Mitnehmers das zugeordnete Scheibenloch im montierten Zustand möglichst vollständig und spielfrei ausfüllen muß, um eine feste, formschlüssige Verbindung zwischen Schnappelement und Scheibenloch und damit zwischen dem Mitnehmer und der Fensterscheibe zu gewährleisten. Die schnappbare Vorrichtung ist aber so aufzubauen, daß dieser montierte Zustand von der Montage zu trennen ist, in der Einführhilfen das Montieren erleichtern und eine Beschä¬ digung der zu montierenden Teile verhindern, ohne daß Zusatzteile oder Montagehilfen an der Fensterscheibe erfor¬ derlich sind. In einer ersten Ausführungsform ist an der Scheibenunterkan- te zumindest im Befestigungsbereich eine Fase vorgesehen, die im Zusammenwirken mit einem vergleichsweise kurzen Ein¬ schnappkonus des Schnappelements dazu dient, die Backen des Mitnehmers zu spreizen und so die Fensterscheibe zum Zwecke der Montage einzuführen. Dabei stimmen die Neigungsrichtun¬ gen der Fase der Scheibenunterkante und des Einführungsko- nuses überein. Je nach Ausführungsvariante der Fase der Scheibenunterkante ist der Einführungskonus des Schnappele¬ ments mehr oder weniger schmal, jedoch höchstens halb so breit wie die Dicke der Fensterscheibe ausgebildet. Der übrige Bereich des Schnappelements füllt das Scheibenloch weitestgehend aus, so daß kein merkliches Spiel mehr auftre¬ ten kann. Sogenannte Umschaltgeräusche werden dadurch ver¬ mieden.The invention is based on the knowledge that the snap element of the driver must fill the assigned window hole as completely and free of play as possible in the assembled state in order to ensure a firm, form-fitting connection between the snap element and window hole and thus between the driver and the window pane. However, the snap-on device is to be constructed in such a way that this assembled state is to be separated from the assembly, in which insertion aids facilitate assembly and prevent damage to the parts to be assembled, without additional parts or assembly aids being required on the window pane. In a first embodiment, a chamfer is provided on the lower edge of the pane, at least in the fastening area, which, in cooperation with a comparatively short snap-in cone of the snap element, serves to spread the jaws of the driver and thus to insert the window pane for the purpose of assembly. The directions of inclination of the chamfer of the lower edge of the pane and of the insertion cone coincide. Depending on the variant of the chamfer of the lower edge of the pane, the insertion cone of the snap element is more or less narrow, but at most half as wide as the thickness of the window pane. The remaining area of the snap element largely fills the disc hole, so that no noticeable play can occur. So-called switching noises are avoided.
Gemäß einer Vorzugsvariante der Erfindung sind beide Mitneh¬ merbacken bezüglich der Fensterscheibe konvex ausgebildet und bieten der Scheibenunterkante in ihrem Basisbereich eine Erweiterung. Im Bereich des kürzesten Abstandes zwi¬ schen den gegenüberliegenden Backen ist das Schnappelement angeordnet. So kann sich die Fensterscheibe in einem gewis¬ sen Winkel im Mitnehmer bewegen und eventuell auftretende Fertigungs- oder Montagetoleranzen spielfrei ausgleichen. Dies beugt gleichzeitig einem Aufspreizen der Backen und der damit verbundenen Gefahr des Lösens der Verbindung zwischen Fensterscheibe und Mitnehmer vor. Erfindungsgemäß können unterschiedliche Ausführungsformen der Fase der Scheibenunterkante zum Einsatz kommen. Neben dem konventionellen keilförmigen Anschleifen der Glaskante gibt es weitere Möglichkeiten. Zum Beispiel kann an die Scheibenunterkante ein Keil angeklebt sein. Bei Verwendung einer Verbundfensterscheibe aus einer Glas- und einer KunststoffScheibe sollte vorzugsweise die Fase nicht nur an der Kunststoffscheibe angeformt sein, sie sollte vielmehr eine seitliche keilförmige Fortsetzung aufweisen und vor¬ zugsweise die gesamte Breite der etwas zurückgesetzten Glasscheibe übergreifen. An dieser Stelle soll darauf hingewiesen werden, daß selbst die versetzte Anordnung von zwei Fensterscheiben in Verbundbauweise geeignet ist, eine erfindungsgemäße keilartige Kontur zur Erleichterung des Verbindungsvorganges von Fensterscheibe und Mitnehmer zu schaffen.According to a preferred variant of the invention, both driver jaws are convex with respect to the window pane and offer an expansion of the lower edge of the pane in its base region. The snap element is arranged in the area of the shortest distance between the opposing jaws. The window pane can thus move in the driver at a certain angle and compensate for any manufacturing or assembly tolerances that may occur without play. At the same time, this prevents the jaws from spreading and the associated risk of loosening the connection between the window pane and the driver. According to the invention, different embodiments of the chamfer of the lower edge of the pane can be used. In addition to conventional wedge-shaped grinding of the glass edge, there are other options. For example, a wedge can be glued to the lower edge of the pane. When using a composite window pane made from a glass pane and a plastic pane, the chamfer should preferably not only be formed on the plastic pane, but rather should have a wedge-shaped extension on the side and preferably encompass the entire width of the somewhat recessed glass pane. At this point it should be pointed out that even the staggered arrangement of two composite window panes is suitable for creating a wedge-like contour according to the invention to facilitate the connection process between the window pane and the driver.
In einer weiteren Ausführungsform ist in der Nähe des ersten Scheibenloches, das dem Schnappelement zugeordnet ist, ein weiteres Scheibenloch vorgesehen. Dieses zweite Scheibenloch befindet sich im Vergleich zum ersten Scheiben¬ loch bezüglich der Scheibenunterkante in einem größeren Abstand. Am oberen freien Ende desjenigen Backens des Mitnehmers, der das Schnappelement trägt, erstreckt sich in Richtung der Fensterscheibe ein Spreizelement mit einer in Montagerichtung abfallenden Einführungsschräge.In a further embodiment, a further disk hole is provided in the vicinity of the first disk hole which is assigned to the snap element. This second disc hole is at a greater distance from the first disc hole with respect to the lower edge of the disc. At the upper free end of the jaw of the driver that carries the snap element, an expansion element extends in the direction of the window pane with an insertion slope that slopes in the mounting direction.
Während des Montagevorganges tritt zunächst die Scheibenun¬ terkante mit der Einführungsschräge des Spreizelements in Eingriff und drückt die beiden Backen des Mitnehmers ausein¬ ander. Somit entsteht der notwendige Montagespal , ohne daß dazu in üblicher Weise auf das Schnappelement einge- wirkt werden muß. Aufgrund dessen ist es nicht notwendig, daß an der Oberseite des Schnappelements eine Einführungs- schräge oder dergleichen vorgesehen werden muß. In der Regel wird ein kurzer kegelförmiger Endbereich für eine problemlose Einführung des Schnappelements in das zugehöri¬ ge Scheibenloch ausreichend sein, wenn diese deckungsgleich übereinander zum Liegen kommen. Ein derart verlängerter Ba¬ sisbereich des Schnappelements vergrößert nicht nur die Be¬ lastbarkeit der Verbindungsvorrichtung, er füllt auch den Hohlraum des Scheibenloches weitestgehend aus, wodurch ein geringeres Spiel zwischen den Bauelementen auftritt . Die durch die Umkehrung der Belastungsrichtung (Scheibe heben, Scheibe senken) sonst auftretenden Umschaltgeräusche können so weitestgehend vermieden werden.During the assembly process, the lower pane edge first engages with the insertion slope of the expansion element and presses the two jaws of the driver apart. This creates the necessary assembly range without having to click on the snap element in the usual way. must be worked. Because of this, it is not necessary that an insertion bevel or the like must be provided on the top of the snap element. As a rule, a short conical end region will be sufficient for a problem-free insertion of the snap element into the associated disk hole if these come to lie congruently one above the other. Such a lengthened base area of the snap element not only increases the loading capacity of the connecting device, it also fills the cavity of the disk hole as far as possible, as a result of which there is less play between the components. The switching noises that otherwise occur due to the reversal of the loading direction (lifting the pane, lowering the pane) can thus be largely avoided.
Hat die Unterkante der Fensterscheibe zum Abschluß des Montagevorganges die Basis des Mitnehmers erreicht, so schnappen das Schnappelement und das Spreizelement in die ihnen zugeordneten Scheibenlöcher ein.When the lower edge of the window pane has reached the base of the driver at the end of the assembly process, the snap element and the expansion element snap into the pane holes assigned to them.
Auch in dieser Ausführungsform besitzen die Backen auf der einander zugewandten Seite eine konvexe Kontur, so daß sich der zwischen den Backen beiderseits des Schnappelements erstreckende Spalt konisch erweitert. Durch diese Gestal¬ tung wird ein begrenztes Schwenken der Fensterscheibe möglich, ohne daß dadurch Spannungen entstehen, die den Mitnehmer zerstören könnten oder die zum Lösen der Verbin¬ dungsvorrichtung führen.In this embodiment, too, the jaws have a convex contour on the side facing one another, so that the gap extending between the jaws on both sides of the snap element widens conically. This design enables the window pane to be pivoted to a limited extent without causing stresses which could destroy the driver or lead to the connection device being released.

Figur 9c - eine schematische Darstellung eines doppel- strängigen Seilfensterhebers. In den Figuren la bis ld sind verschiedene Phasen des Mon¬ tagevorganges einer mit einem Scheibenloch 10 versehenen Verbundfensterscheibe la an einen Mitnehmer 3 dargestellt. Die Verbundfensterscheibe la besteht aus einer Scheibe 11a und einer Scheibe 12a, die aufeinander geklebt und deren Scheibenunterkanten 110a, 120a zueinander versetzt angeord¬ net sind. Dadurch entsteht ein keilförmiger Absatz, der im Sinne der Erfindung als Fase aufgefaßt wird. Der Mitnehmer 3 besteht aus zwei gegenüberliegenden Backen 31, 32, die über eine gemeinsame Basis 33 miteinander in Verbindung stehen und über die Befestigungsplatte 34 an einem Fenster¬ heber befestigt werden können. Einer der elastisch spreizba¬ ren Backen 32 trägt ein stift- oder bolzenartiges Schnappe¬ lement 30, welches dem Scheibenloch 10 zugeordnet ist. Das Schnappelement besitzt einen im wesentlichen zylindrischen Bereich 301, an dessen freiem Ende sich ein Einführungsko¬ nus 302 mit der schrägverlaufenden Mantelfläche 303 an¬ schließt. Der Verlauf der Schräge der Mantelfläche 303 entspricht der Neigungsrichtung der stufenförmig (keilför¬ mig) versetzten Scheibenunterkanten 110a, 120a der Verbund¬ fensterscheibe la.Figure 9c - a schematic representation of a double-strand cable window lifter. FIGS. 1a to 1d show different phases of the assembly process of a composite windowpane la provided with a pane hole 10 on a driver 3. The composite window pane la consists of a pane 11a and a pane 12a which are glued to one another and whose lower pane edges 110a, 120a are arranged offset with respect to one another. This creates a wedge-shaped shoulder, which is understood as a chamfer in the sense of the invention. The driver 3 consists of two opposing jaws 31, 32 which are connected to one another via a common base 33 and can be fastened to a window lifter via the fastening plate 34. One of the elastically expandable jaws 32 carries a pin-like or bolt-like snap element 30, which is assigned to the disk hole 10. The snap element has an essentially cylindrical region 301, at the free end of which an insertion cone 302 with the inclined lateral surface 303 adjoins. The course of the slope of the lateral surface 303 corresponds to the direction of inclination of the step-like (wedge-shaped) offset lower window edges 110a, 120a of the composite window pane la.
Die dargestellte Ausführungsform des Mitnehmers 3 stellt mit ihrem im Bereich der Basis 33 der Backen 31, 32 vorgese¬ henen Erweiterung 35 in Verbindung mit der konvex ausgebil¬ deten inneren Kontur der Backen 31, 32 eine Vorzugsvariante der Erfindung dar. Sie gewährleistet einen spannungsfreien Sitz von Scheibe und Mitnehmer, was später noch näher erläutert wird. Figur la zeigt die Verbundfensterscheibe la unmittelbar vor ihrer Montage am Mitnehmer 3. Die Dicke der einzelnen Scheiben 11a, 12a entspricht im wesentlichen der Breite B des Einführungskonuses 302. Um eine sichere Montage zu gewährleisten, ist darauf zu achten, daß die Breite B der schrägverlaufenden Mantelfläche 303 des Einführungskonuses 302 wenigstens der Scheibendicke entspricht, an die sich eine in gleicher Schräglage wie die Mantelfläche 303 verlau¬ fende Führungsfläche der Fensterscheibe anschließt. Im vorliegenden Beispiel sind lediglich die Ränder der Stirn¬ flächen 110a, 112a der einzelnen Scheiben 11a, 12a be¬ schliffen, so daß als notwendige Breite B des Einführungsko¬ nuses annähernd die Dicke der Scheibe 11a festgelegt werden muß.The illustrated embodiment of the driver 3, with its extension 35 provided in the area of the base 33 of the jaws 31, 32 in conjunction with the convex inner contour of the jaws 31, 32, represents a preferred variant of the invention. It ensures a tension-free fit disc and driver, which will be explained in more detail later. Figure la shows the composite window pane la immediately before it is mounted on the driver 3. The thickness of the individual panes 11a, 12a essentially corresponds to the width B of the insertion cone 302. In order to ensure secure installation, it must be ensured that the width B is the inclined one The lateral surface 303 of the insertion cone 302 corresponds at least to the pane thickness, which is followed by a guide surface of the window pane running in the same inclined position as the lateral surface 303. In the present example, only the edges of the end faces 110a, 112a of the individual disks 11a, 12a are ground, so that approximately the thickness of the disk 11a must be defined as the necessary width B of the insertion cone.
Figur lb zeigt den Mitnehmer 3 in halb gespreizter Stel¬ lung, wobei sich die Scheibe 11a zwischen die linke Backe 31 und die Stirnfläche des Schnappelements 30 geschoben hat und die Unterkante 120a der benachbarten Scheibe 12a be¬ reits im Kontakt mit der Mantelfläche 303 des Einführungsko¬ nuses 302 steht. Bei einem weiteren Eindringen der Verbund¬ fensterscheibe la in den Mitnehmer 3 kommt es zur maximalen Spreizung der Backen 31, 32 ( siehe Figur lc) . Mit dem Einrasten des Schnappelements 30 in das Scheibenloch 10 ist der Montagevorgang beendet. Gemäß Figur ld steht dabei die Scheibenunterkante 110a der Scheibe 11a auf der Basis 33 des Mitnehmers 3 auf.FIG. 1b shows the driver 3 in a half-spread position, the washer 11a being pushed between the left jaw 31 and the end face of the snap element 30 and the lower edge 120a of the adjacent washer 12a already in contact with the outer surface 303 of the insertion member ¬ nuses 302 stands. Upon further penetration of the composite window pane la into the driver 3, the jaws 31, 32 are maximally spread (see FIG. 1c). The assembly process is ended when the snap element 30 engages in the disk hole 10. According to FIG. 1d, the lower pane edge 110a of the pane 11a stands on the base 33 of the driver 3.
In Figur 2 ist eine schnappbare Scheibenbefestigung gemäß dem Stand der Technik dargestellt. Auch sie besteht aus zwei spreizbaren Backen 31', 32' , die über eine gemeinsame Basis 33' verbunden und mittels einer Befestigungsplatte 34' mit einem Fensterheber verbindbar sind. Dem Scheiben¬ loch 10 der Fensterscheibe ld ist das einstückig an die Backe 31 angeformte Schnappelement 30' zugeordnet. Die Scheibenunterkante 110b ist im wesentlichen flach ausgebil¬ det, lediglich ihre Ränder sind beschliffen.FIG. 2 shows a snap-on pane attachment according to the prior art. It also consists of two expandable jaws 31 ', 32' which are connected via a common base 33 'and by means of a fastening plate 34 'can be connected to a window regulator. The snap hole 30 'which is integrally formed on the jaw 31 is assigned to the disk hole 10 of the window disk 1d. The lower edge of the pane 110b is essentially flat, only its edges are ground.
Die Darstellung von Figur 2 zeigt einen kritischen Zustand der Verbindungsvorrichtung mit einer verkantet, im Mitneh¬ mer 3' liegenden Fensterscheibe lb. Ein solcher Zustand kann beispielsweise bei extremen Belastungszuständen (z.B. angefrorene Fensterscheibe) auftreten. Dies führt nicht nur zu hohen Spannungen in der Verbindungsvorrichtung, was insbesondere unter tiefen Temperaturen auch zu Brüchen führen kann, sondern auch zu einem zumindest teilweisen Verlust des Formschlusses zwischen dem Scheibenloch 10 und dem Schnappelement 30' . Es besteht somit eine große Gefahr des Lösens der Verbindung.The illustration in FIG. 2 shows a critical state of the connecting device with a tilted window pane 1b located in the driver 3 '. Such a condition can occur, for example, under extreme load conditions (e.g. frozen window pane). This leads not only to high tensions in the connecting device, which can also lead to fractures, particularly at low temperatures, but also to an at least partial loss of the positive connection between the disk hole 10 and the snap element 30 '. There is therefore a great risk of loosening the connection.
Bei der erfindungsgemäßen Vorzugsvariante des Mitnehmers 3 gemäß Figur 3 können solche negativen Spannungen nicht auftreten. Da sich der Freiraum ausgehend von dem Schnappe¬ lement 30 sowohl nach oben als auch nach unten erweitert, werden Schwenkbewegungen der Fensterscheibe lc um einen scheinbaren Schwenkpunkt im Bereich des Scheibenloches 10 in einem beschränkten Bereich spannungsfrei ausgeführt. Eine Gefahr für das Lösen der Verbindung besteht dadurch nicht .In the preferred variant of the driver 3 according to FIG. 3 according to the invention, such negative tensions cannot occur. Since the free space extends from the snap element 30 both upwards and downwards, pivoting movements of the window pane 1c around an apparent pivot point in the area of the pane hole 10 are carried out in a limited area without tension. There is no danger of loosening the connection.
Figur 4 zeigt die Kombination einer konventionellen Fenster¬ scheibe mit einer im wesentlichen ebenen Scheibenunterkante mit einer daran angesetzten Montagehilfe 2. Sie besteht aus einem Keil 21 mit einer Fase (Einführungsschräge) 22 und einem seitlichen Steg 20 zur Herstellung einer Klebverbin¬ dung mit der Fensterscheibe lb. Dieses Montagehilfsmittel 2 wird vorzugsweise als Kunststoffteil ausgeführt.FIG. 4 shows the combination of a conventional window pane with an essentially flat lower window edge with a mounting aid 2 attached to it. It consists of a wedge 21 with a chamfer (insertion bevel) 22 and a side web 20 for producing an adhesive connection with the window pane 1b. This assembly aid 2 is preferably designed as a plastic part.
In Figur 5 ist eine Verbundfensterscheibe ld, bestehend aus einer KunststoffScheibe lld und einer Glasscheibe 12d, dargestellt, wobei die KunststoffScheibe lld mit ihrem keilförmigen Ende die Scheibenunterkante 120d der Glasschei¬ be 12 d überragt. Die schrägverlaufende Scheibenunterkante llOd überdeckt mit ihrem keilförmigen Fortsatz 111 die Scheibenunterkante 120d fast vollständig. Die Keilspitze 112 besitzt nur einen sehr geringen Durchmesser so daß auch die Breite B des Einführungskonuses sehr kurz ausgeführt sein kann. Dadurch gewinnt der zylindrische Bereich 301 des Schnappelements 30 an Länge, wodurch die Tragfähigkeit der erfindungsgemäßen Verbindungsvorrichtung verbessert wird.FIG. 5 shows a composite window pane ld consisting of a plastic pane lld and a glass pane 12d, the plastic pane lld projecting beyond the lower pane edge 120d of the glass pane 12d with its wedge-shaped end. With its wedge-shaped extension 111, the sloping lower edge 11d of the window almost completely covers the lower edge 120d. The wedge tip 112 has only a very small diameter so that the width B of the insertion cone can also be made very short. As a result, the cylindrical region 301 of the snap element 30 becomes longer, which improves the load-bearing capacity of the connecting device according to the invention.
Die Verbundfensterscheibe le besteht gemäß Figur 6 aus zwei aufeinander geklebten Glasscheiben lle, 12e deren untere Kanten llOe, 120e zueinander versetzt angeordnet sind. Diese Scheibenunterkanten sind stark abgerundet und besit¬ zen im wesentlichen die Kontur eines Halbkreises. Erfin¬ dungsgemäß ergibt sich daraus die Notwendigkeit, die Breite B des Einführungskonuses 302 des Schnappelements 30 mit einer solchen Mindestbreite festzusetzen, die der halben Dicke einer Scheibe lle, 12c entspricht. Somit ist ein problemloses Einführen der Fensterscheibe le in den Spalt zwischen den Backen 31, 32 eines erfindungsgemäßen Mitneh¬ mers problemlos gewährleistet. In den Figuren 7a bis 7d sind verschiedene Phasen des Monta¬ gevorganges einer Fensterscheibe 1 an den Mitnehmer 3 eines Fensterhebers dargestellt. Der erfindungsgemäße Mitnehmer 3 besteht aus zwei gegenüberliegenden Backen 31, 32, die über eine gemeinsame Basis 33 verbunden sind und mittels der Befestigungsplatte 34 an einem Fensterheber festliegen. An einen der beiden Backen 32 ist nicht nur das Schnappelement 30, sondern auch ein keilförmiges Spreizelement 4 einstük- kig angeformt, wobei das Spreizelement 4 in einem lichten Abstand A2 oberhalb des Schnappelements 30 liegt. Jedem dieser nach innen ragenden Teile 30, 4 ist in der Fenster¬ scheibe 1 ein separates Scheibenloch 10, 13 zugeordnet.According to FIG. 6, the composite window pane le consists of two glass panes lle, 12e glued to one another, the lower edges 11oe, 120e of which are offset from one another. These lower edge of the pane are strongly rounded and essentially have the contour of a semicircle. According to the invention, this results in the need to fix the width B of the insertion cone 302 of the snap element 30 with a minimum width which corresponds to half the thickness of a disk 11, 12c. A problem-free insertion of the window pane le into the gap between the jaws 31, 32 of a driver according to the invention is thus easily ensured. FIGS. 7a to 7d show different phases of the assembly process of a window pane 1 on the driver 3 of a window lifter. The driver 3 according to the invention consists of two opposing jaws 31, 32 which are connected via a common base 33 and are fixed to a window regulator by means of the fastening plate 34. Not only the snap element 30, but also a wedge-shaped spreading element 4 is integrally formed on one of the two jaws 32, the spreading element 4 being at a clear distance A 2 above the snap element 30. Each of these inwardly projecting parts 30, 4 is assigned a separate window hole 10, 13 in the window pane 1.
Figur 7a zeigt die erste Phase des Montagevorganges, bei dem die Scheibenunterkante 100 auf die Einführungsschräge 40 des Spreizelements 4 trifft. Bei einer weiteren Verschie¬ bung der Fensterscheibe 1 in Richtung des Mitnehmers 3 kommt es zur Spreizung der Backen 31, 32, wodurch gleichzei¬ tig auch das Schnappelement 30 von der gegenüberliegenden Backe 31 abgehoben wird und einen Einführungsspalt freigibt (siehe Figur 7b) .FIG. 7 a shows the first phase of the assembly process, in which the lower pane edge 100 meets the insertion slope 40 of the expansion element 4. When the window pane 1 is displaced further in the direction of the driver 3, the jaws 31, 32 expand, which means that the snap element 30 is also lifted off the opposing jaw 31 and releases an insertion gap (see FIG. 7b).
Die Länge L des Spreizelements 4 stimmt vorzugsweise etwa mit der Länge des Schnappelements 30 überein oder ist sogar noch etwas länger. Sollte jedoch die Länge L des Spreizele¬ ments 4 kürzer sein als die Länge des Schnappelements 30, so ist ein hinreichend großer konischer Bereich 302 zu wählen, damit die vordringende Scheibenunterkante 100 nicht am zylindrischen Bereich 301 des Schnappelements blockiert wird. Figur 7c zeigt eine Montagephase, bei der die Scheibenunter¬ kante 100 der Fensterscheibe 1 bereits bis zur Stirnfläche des Schnappelements 30 vorgedrungen ist. Für den Fall, daß das Spreizelement 4 während des Montageprozesses unmittel¬ bar am Scheibenloch 10 vorbeigeführt wird und darin einra¬ sten kann, sollte der lichte Abstand A2 zwischen dem Sprei¬ zelement 4 und dem Schnappelement 30 kleiner gewählt wer¬ den, als der Abstand A. zwischen dem unteren Kantenbereich des Scheibenlochs 10 und der Scheibenunterkante 100. Ande¬ renfalls könnte ein weiteres Vordringen der Fensterscheibe 1 durch das Schnappelelment 30 infolge des einrastenden Spreizelements 4 blockiert werden, bzw. es müßte ein ver¬ hältnismäßig großer konischer Bereich 302 am Schnappelement 30 vorgesehen werden. Diesem Problem kann jedoch auch da¬ durch begegnet werden, daß das Spreizelement 4 und das Schnappelement 30 seitlich versetzt zueinander angeordnet werden. Natürlich muß dann auch die Anordnung der Scheiben¬ löcher 10 und 13 in analoger Weise erfolgen.The length L of the expansion element 4 preferably corresponds approximately to the length of the snap element 30 or is even somewhat longer. However, if the length L of the expansion element 4 is shorter than the length of the snap element 30, a sufficiently large conical area 302 must be selected so that the protruding lower pane edge 100 is not blocked on the cylindrical area 301 of the snap element. FIG. 7c shows an assembly phase in which the lower pane edge 100 of the window pane 1 has already reached the end face of the snap element 30. In the event that the expansion element 4 is guided past the window hole 10 directly during the assembly process and can snap into it, the clear distance A 2 between the expansion element 4 and the snap element 30 should be chosen smaller than that Distance A. between the lower edge area of the window hole 10 and the lower window edge 100. Otherwise, further advancement of the window pane 1 by the snap element 30 could be blocked as a result of the latching expansion element 4, or a relatively large conical area 302 would have to be Snap element 30 can be provided. However, this problem can also be countered by arranging the expansion element 4 and the snap element 30 laterally offset from one another. Of course, the arrangement of the disk holes 10 and 13 must then be carried out in an analogous manner.
Figur 7d zeigt die Verbindungsvorrichtung nach Abschluß der Montage mit in das Scheibenloch 10 bzw. 13 eingerastetem Schnappelement 30 bzw. Spreizelement 4.FIG. 7d shows the connecting device after the completion of the assembly with snap element 30 or expansion element 4 latched into the window hole 10 or 13.
Eine Vorzugsvariante der Erfindung sieht die Verwendung von konvex ausgebildeten spreizbaren Backen 31, 32 vor, wobei beiderseits des Schnappelements 30 in Montagerichtung ein sich erweiternder Raum 35 für die Fensterscheibe 1 bildet. Im Falle des schematisch in Figur 8 dargestellten Einwir- kens seitlicher Kräfte auf die Fensterscheibe 1, die zu ihrem Verkippen im Mitnehmer 3 führen, treten keine Spannun¬ gen auf, die zu einem Bruch oder gar zum Lösen der Verbin¬ dungsvorrichtung führen könnten. Die Fensterscheibe 1 kann im Mitnehmer 3 in einem verhältnismäßig großen Winkelbe- reich schwenken, wobei der Scheibenunterkante 100 im Be¬ reich der Basis 33 des Mitnehmers 3 die Erweiterung 35 als Bewegungsfreiraum zur Verfügung steht.A preferred variant of the invention provides for the use of convexly designed expandable jaws 31, 32, an expanding space 35 for the window pane 1 forming on both sides of the snap element 30 in the mounting direction. In the case of the lateral forces acting schematically in FIG. 8 on the window pane 1, which lead to their tilting in the driver 3, no stresses occur which could lead to a breakage or even a loosening of the connecting device. The window pane 1 can pivot in the driver 3 in a relatively large angular range, the lower edge of the pane 100 being available in the area of the base 33 of the driver 3, the extension 35 as freedom of movement.
Die erfindungsgemäßen Verbindungsvorrichtungen sind beson¬ ders vorteilhaft für Seilfensterheber einsetzbar, wie dies in den Figur 9a bis 9c anhand einer schematischen Drauf¬ sicht auf zwei Fensterscheiben in Relation zu einem doppel- strängigen Seilfensterheber dargestellt ist.The connecting devices according to the invention can be used particularly advantageously for cable window lifters, as is shown in FIGS. 9a to 9c on the basis of a schematic plan view of two window panes in relation to a double-strand cable window lifter.
Figur 9a zeigt eine Fensterscheibe 1, in deren Befestigungs¬ bereiche 90 Ausnehmungen 92 vorgesehen sind, die von seitlichen, konischen Führungsflächen 91 für den Mitnehmer 3 begrenzt sind.
