Description

Die Erfindung geht aus von einer Befestigungsvorrichtung für eine Arbeitsplatte eines schrankförmigen Haushaltgerätes, die eine quer zur Befestigungsrichtung definierte Lage haben soll und mit einem rückwärtigen Umbug für die rückwärtige Befestigung der Arbeitsplatte mittels mindestens einem Haltezapfen am Korpus des Haushaltgerätes versehen ist, bei dem der Haltezapfen einen Kulissenabschnitt aufweist, mittels dem der Haltezapfen ein Langloch im Umbug durchdringt und den Umbug in einer definierten Höhenposition hält.The invention relates to a fastening device for a worktop of a cupboard-shaped household appliance, which should have a transversely to the fastening direction defined position and is provided with a rear Umbug for the rear attachment of the worktop by means of at least one retaining pin on the body of the household appliance, wherein the retaining pin a Having gate section, by means of which the retaining pin penetrates a slot in the Umbug and holds the Umbug in a defined height position.

Eine solche Befestigungsvorrichtung ist aus der DE 74 11 413 U1 bekannt. Darin ist zur Vermeidung von Wärmeverwerfungen der Arbeitsplatte der rückwärtige Umbug nur an einer Stelle (mittelbar) fest mit dem Korpus des Haushaltgerätes verschraubt. Alle anderen Verbindungen sind mittels eines Haltezapfens, der ein Langloch im Umbug durchdringt und den Umbug in einer definierten Höhenposition hält, ihm aber in Querrichtung genügend Spielraum lässt, hergestellt.Such a fastening device is known from DE 74 11 413 U1 known. This is to prevent heat distortions of the worktop of the rear Umbug only at one point (indirectly) firmly bolted to the body of the household appliance. All other connections are made by means of a holding pin, which penetrates a slot in the Umbug and holds the Umbug in a defined height position, but leaves him enough latitude in the transverse direction produced.

Diese Befestigungsart genügt aber einem Anspruch nicht, der entsteht, wenn in Bezug auf einen anderen Teil des Haushaltgerätes, der in derselben Ebene befestigt ist wie die Arbeitsplatte, z. B. bei einer Waschmaschine ein Bedienungsteil, das in den oberen Flächenbereich hineinragt. Durch Fertigungstoleranzen im Gehäuse, an der Arbeitsplatte und ggf. einem weiteren Teil an der Oberseite des Gehäuses, z. B. einer Bedienblende, kann es zu Spaltbildungen zwischen den genannten Bauteilen kommen. Dann muss die Position der Arbeitsplatte auf die Position des Gehäuses bzw. dieses anderen Teils hin ausgerichtet werden können, was bei der bekannten Befestigungsvorrichtung nicht möglich ist, weil die Arbeitsplatte an einer Stelle nämlich unjustierbar fest verschraubt ist. Da aber die beiden Teile (z. B. Arbeitsplatte und Bedienteil) nicht in Querrichtung zueinander versetzt montiert sein sollen, was die optische Wirkung stark beeinträchtigen würde, muss die Befestigungsvorrichtung der Arbeitsplatte eine Querjustage ermöglichen.However, this attachment does not satisfy a claim that arises when, with respect to another part of the household appliance, which is attached in the same plane as the worktop, z. B. in a washing machine, an operating part which projects into the upper surface area. By manufacturing tolerances in the housing, on the worktop and possibly another part at the top of the housing, for. As a control panel, it may lead to gap formation between said components. Then, the position of the worktop must be able to be aligned with the position of the housing or this other part, which is not possible in the known fastening device, because the worktop is screwed unjustly fixed at one point. But since the two parts (eg worktop and control panel) should not be mounted offset in the transverse direction to each other, which would greatly affect the visual effect, the mounting device of the worktop must allow Querjustage.

Aus dem US-Patent 4,610,587 geht ein Haltezapfen zum Befestigen zweier Platten zueinander hervor, welcher Haltezapfen einen Kulissenabschnitt mit einem rechteckigen Querschnitt aufweist und Löcher mit entsprechenden rechteckigen Formen in den beiden Platten durchdringt.From the U.S. Patent 4,610,587 is a holding pin for fixing two plates to each other, which holding pin has a gate section with a rectangular cross-section and penetrates holes with corresponding rectangular shapes in the two plates.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Befestigungsvorrichtung der eingangs genannten Art anzugeben, bei der ein in der Massenfertigung geeigneter Toleranzausgleich zwischen der Arbeitsplatte und dem schrankförmigen Gehäuse eines Haushaltgerätes bzw. einem weiteren auf der Oberseite des Gehäuses montierten Teil stattfinden kann.The invention is therefore based on the object to provide a fastening device of the type mentioned, in which a suitable in mass production tolerance compensation between the countertop and the cabinet-shaped housing of a household appliance or another mounted on the top of the housing part can take place.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Umbug ausschließlich mittels mehrerer Haltezapfen gehalten ist, deren Kulissenabschnitte jeweils einen wenigstens nahezu rechteckigen Querschnitt aufweisen, wobei jeder Haltezapfen in Fortsetzung des Kulissenabschnitts einen Schaft aufweist, der zum Eindringen in eine Öffnung am Korpus des Haushaltgerätes vorgesehen ist, und die Schlüsselweite des Kulissenabschnitts eine geringere Größe hat als der Durchmesser des anschließenden Schafts.According to the invention, this object is achieved in that the Umbug is held exclusively by a plurality of retaining pins whose gate sections each have an at least nearly rectangular cross-section, each retaining pin in continuation of the gate section has a shaft which is provided for penetration into an opening on the body of the household appliance , and the key width of the gate section has a smaller size than the diameter of the adjoining shaft.

Vorteilhafterweise lässt sich nun die Arbeitsplatte gegenüber allen anderen Teilen justieren. Dadurch kann die Arbeitsplatte in eine Position gerichtet werden, die zu den anderen Gehäuseteilen exakt ausgerichtet ist, so dass kein Versatz das ästhetische Empfinden stört. Alle Dichtigkeitsprüfungen (Spritzbogenprüfung, Verschütt-Test) können nun bestanden werden.Advantageously, it is now possible to adjust the worktop over all other parts. Thereby, the worktop can be directed in a position that is exactly aligned with the other housing parts, so that no offset disturbs the aesthetic feeling. All leak tests (spray arch test, spill test) can now be passed.

Ein weiterer Fehlerfall, bei dem die Arbeitsplatte und ggf. die Bedienblende aus Toleranzgründen je ein Größtmaß haben und das Gehäuse ein Kleinstmaß, kann durch die erfindungsgemäße Lösung vermieden werden. Dieser Fehlerfall würde zu einer sichtbaren Verspannung der Arbeitsplatte gegenüber der Bedienblende führen, die im Bedienblendenbereich sogar Funktionsstörungen auslösen könnte. Die erfindungsgemäße Befestigungsvorrichtung kann im Gegensatz zum Stand der Technik diese Gefahr vermeiden.Another fault, in which the worktop and possibly the control panel for tolerance reasons ever have a maximum size and the housing a small size, can be avoided by the inventive solution. This fault would lead to a visible distortion of the worktop relative to the control panel, which could even cause malfunction in the control panel area. The fastening device according to the invention can avoid this danger in contrast to the prior art.

Ferner entstehen keine Verformungen mehr durch Verspannen der Bauteile, keine hässliche Spaltbildung zwischen Bedienblende und Arbeitsplatte; es werden keine hohen Toleranzanforderungen an die einzelnen Bauteile gestellt und es kann ein definierter leichter Anpressdruck von der Arbeitsplatte zur Bedienblende eingestellt werden.Furthermore, no more deformations caused by distortion of the components, no ugly gap formation between control panel and worktop; There are no high tolerance requirements placed on the individual components and it can be set a defined light contact pressure from the worktop to the control panel.

Die rechteckige Form der Kulissenabschnitte verhindert, dass sich der Haltezapfen in der vormontierten Position im Langloch verdrehen kann.The rectangular shape of the link sections prevents the retaining pin can rotate in the preassembled position in the slot.

In besonders vorteilhafter Weise weist der Haltezapfen oberhalb des Kulissenabschnittes einen kopfähnlichen Ansatz auf. Mit diesem Ansatz liegt der Haltezapfen in definierter Weise an der Außenoberfläche des Umbugs und stellt daher eine reproduzierbare Position her.In a particularly advantageous manner, the retaining pin above the gate section on a head-like approach. With this approach, the retaining pin lies in a defined manner on the outer surface of the Umbugs and therefore produces a reproducible position.

Außerdem kann der Haltezapfen in vorteilhafter Weise eine axiale Bohrung aufweisen, die vom Befestigungselement durchdringbar ist. Auf diese Weise lassen sich Haltezapfen und Umbug gemeinsam am Gehäuse fixieren.In addition, the retaining pin may advantageously have an axial bore which is penetratable by the fastening element. In this way, holding pin and Umbug fix together on the housing.

Diese Vorteil lässt sich dadurch noch weiter ausbauen, dass der Haltezapfen in Fortsetzung des Kulissenabschnitts einen Schaft aufweist, der nach Art eines Dübels geschlitzt und zum Eindringen in eine Öffnung am Korpus des Haushaltgerätes vorgesehen ist, wo er durch das Befestigungselement spreizend befestigt werden kann. Dann kann bei der Montage nämlich der Haltezapfen zusammen mit dem leicht eingedrehten Befestigungselement (in der Regel eine Schraube) durch das Langloch im Umbug in das Befestigungsloch im Gehäuse eingesteckt werden. Anschließend wird durch Eindrehen der Schraube der Dübelteil des Haltezapfens im Befestigungsloch gespreizt und der Haltezapfen in bekannter Weise im Befestigungsloch sicher befestigt. Dazu kann die Arbeitplatte in einer zu den anderen Gehäuseteilen justierten Position gehalten werden.This advantage can be further enhanced by the fact that the retaining pin in continuation of the gate section has a shaft which is slotted in the manner of a dowel and provided for penetration into an opening on the body of the household appliance, where it can be fastened by spreading the fastener. Then, during assembly, namely the retaining pin together with the slightly screwed fastener (usually a screw) are inserted through the slot in the bend in the mounting hole in the housing. Then, by screwing the screw of the dowel part of the retaining pin is spread in the mounting hole and the retaining pin securely fastened in a known manner in the mounting hole. For this purpose, the worktop can be kept in a position adjusted to the other housing parts.

Vorteilhafterweise reicht der Schlitz in einer weiteren Ausbildung der Erfindung bis in den kopfähnlichen Ansatz und hat die Schlüsselweite des Kulissenabschnitts eine geringere Größe als der Durchmesser des anschließenden Schafts. Dadurch können die beiden Schaftteile im Umfang der Schlitzbreite beim Einsetzen des Haltezapfens in das Langloch des Umbugs zusammen gedrückt werden. In der Endposition ist der Haltezapfen am Kulissenabschnitt locker gehalten. Seine rechteckige Form bewahrt den Haltezapfen zusammen mit der Innenkontur des Langloches vor Verdrehen.Advantageously, the slot extends in a further embodiment of the invention into the head-like approach and has the wrench size of the gate section a smaller size than the diameter of the adjoining shaft. As a result, the two shaft parts can be pressed together in the circumference of the slot width when inserting the retaining pin in the slot of the Umbugs. In the end position of the retaining pin is held loosely on the gate section. Its rectangular shape prevents the retaining pin from twisting together with the inner contour of the elongated hole.

Wenn der kopfähnliche Ansatz seitlich zwei ohrenförmige Fortsätze hat, deren Innenabstand mindestens gleichgroß ist wie der Durchmesser der in Befestigungslage hier liegende Teil des Befestigungselements, und die Schlitze bis in die Fortsätze reichen, kann ein Kopf des Befestigungselements geschützt zwischen den ohrenförmigen Fortsätzen liegen. Außerdem führen die beiden Ohren das Befestigungselement bei der Montage sicherer in die axiale Bohrung.When the head-like lug has laterally two ears whose inside distance is at least equal to the diameter of the part of the fastener lying in the mounting position, and the slots extend into the projections, a head of the fastener can be protected between the two lie ear-shaped projections. In addition, the two ears guide the fastener during assembly safer in the axial bore.

In einer weiteren vorteilhaften Weiterbildung der Erfindung sind im kopfähnlichen Ansatz in Höhe der Kulissenabschnitte Durchbrechungen vorgesehen, deren lichte Weite zum Einführen eines Schraubendrehers geeignet ist. Dadurch können zum Demontieren der Arbeitsplatte nach Entfernen der Befestigungselemente die beiden Schaftteile mittels Schraubendrehern oder eines anderen geeigneten Werkzeugs gegeneinander gedrückt werden, damit sie sich von der Wand des Befestigungsloches lösen und den Schaft enger machen, um durch das Langloch des Umbugs zurück gezogen werden zu können.In a further advantageous embodiment of the invention openings are provided in the head-like approach at the height of the gate sections, the clear width is suitable for inserting a screwdriver. As a result, to disassemble the worktop after removing the fasteners, the two shaft parts can be pressed against each other by means of screwdrivers or other suitable tool so that they detach from the wall of the mounting hole and make the shaft narrower to be pulled back through the slot of Umbugs can ,

Die in Fig. 1 dargestellte Arbeitsplatte 1 ist an der Oberseite eines angedeuteten Korpus 3 eines schrankförmigen Haushaltgerätes mit einem weiteren Teil, hier einer Bedienblende 2, die zur Vorderseite des Gehäuses hin leicht bogenförmig abfällt, kombiniert. An der vorderen Kante ist die Arbeitsplatte 1 in nicht dargestellter Weise mit der Unterseite auf der Oberseite des Gehäusekorpus 3 befestigt. An der Rückseite hat die Arbeitsplatte 1 einen Umbug 4 mit Langlöchern 5, die zur Befestigung der Arbeitsplatte 1 in Richtung auf die Vorderseite des Korpus 3 hin dienen.In the Fig. 1 illustrated worktop 1 is at the top of an indicated body 3 of a cupboard-shaped household appliance with another part, here a control panel 2, which drops slightly arcuate towards the front of the housing combined. At the front edge of the worktop 1 is fixed in a manner not shown with the bottom on top of the housing body 3. At the back of the worktop 1 has a fold 4 with slots 5, which serve to fasten the worktop 1 in the direction of the front of the body 3 out.

In Fig. 2 ist eine rückwärtige Ecke der Arbeitplatte 1 ausschnittsweise vergrößert dargestellt. In der Näher der unteren Kante des Umbugs 4 befindet sich ein Langloch 5, hinter dem der obere Rand eines Befestigungslochs 6 des Korpus 3 zu erkennen ist. In dieses Befestigungsloch 6 wird unter Durchdringung des Langloches 5 in Pfeilrichtung ein Haltezapfen 7 gemäß Fig. 3 eingesetzt und mittels einer Schraube (Fig. 4) befestigt. Während des Montagevorgangs kann dann die Lage der Arbeitsplatte 1 im Umfang des durch die Langlöcher 5 gegebenen Freiheitsgrades seitlich justiert werden. Hierdurch sind etwa vorhandene Maßtoleranzen ausgleichbar.In Fig. 2 is a rear corner of the worktop 1 partially enlarged shown. In the vicinity of the lower edge of the Umbugs 4 is a slot 5, behind which the upper edge of a mounting hole 6 of the body 3 can be seen. In this mounting hole 6 is under penetration of the elongated hole 5 in the direction of arrow a retaining pin 7 according to Fig. 3 inserted and by means of a screw ( Fig. 4 ) attached. During the assembly process, the position of the work surface 1 can then be adjusted laterally within the scope of the given by the slots 5 degree of freedom. As a result, any existing dimensional tolerances can be compensated.

Ein Haltezapfen 7 hat gemäß Fig. 3 eine axiale Bohrung 17 und zwei Schaftteile 8 und 9, die durch einen Längsschlitz 10 entlang der Mittelachse des Haltezapfens 7 entstehen. Am oberen Ende trägt der Haltezapfen 7 einen kopfähnlichen Ansatz 12 mit seitlich angeordneten ohrenähnlichen Fortsätzen 11. Der Schlitz ist bis in diese Fortsätze 11 geführt und gibt dem Schaft 8, 9 dadurch eine enorme Durchmesser-Elastizität, so dass die Schaftteile 8, 9 beim Einführen des Haltezapfens 7 in das Langloch 5 und in das Befestigungsloch 6 aufeinander zu weichen.A retaining pin 7 has according to Fig. 3 an axial bore 17 and two shaft parts 8 and 9, which arise through a longitudinal slot 10 along the central axis of the retaining pin 7. At the upper end of the retaining pin 7 carries a head-like projection 12 with laterally disposed ears-like projections 11. The slot is guided into these extensions 11 and gives the shaft 8, 9 thereby an enormous diameter elasticity, so that the shaft parts 8, 9 during insertion of the holding pin 7 in the slot 5 and in the mounting hole 6 to each other.

Direkt unterhalb des kopfähnlichen Ansatzes 12 hat der Haltezapfen 7 einen Kulissenbereich mit ebenen Flächen 13, die dem Haltezapfen 7 an dieser Stelle einen nahezu rechteckigen Querschnitt verleihen. Die Kulissenflächen 13 korrespondieren mit Flächen 14 von Durchbrechungen 15 im kopfähnlichen Ansatz 12, die zum Einführen eines Werkzeugs, wie einem Schraubendreher, vorgesehen sind, mittels dem die Schaftteile 8 und 9 in eingebauter Lage aufeinander zu gepresst werden können, um den Haltezapfen 7 zwecks Demontage der Arbeitsplatte 1 aus dem Befestigungsloch 6 und dem Langloch 5 zu lösen.Directly below the head-like projection 12 of the retaining pin 7 has a gate area with flat surfaces 13, which give the retaining pin 7 at this point a nearly rectangular cross-section. The slide surfaces 13 correspond to surfaces 14 of apertures 15 in the head-like projection 12, which are provided for insertion of a tool, such as a screwdriver, by means of which the shaft parts 8 and 9 can be pressed together in an installed position to the retaining pin 7 for the purpose of disassembly the worktop 1 from the mounting hole 6 and the slot 5 to solve.

Gemäß Fig. 4 sind die Haltezapfen 7 nach dem Einrasten ins Langloch 5 durch die angeformten Kulissenflächen 13 verdrehgesichert und durch den Hinterschnitt fixiert, der durch einen geringeren Abstand (Schlüsselweite) der Kulissenflächen 13 zueinander als der Schaft 8, 9 im Durchmesser misst, entstanden ist. Dabei ist der Abstand der Kulissenflächen 13 etwa gleich groß wie die lichte Weite der Langlöcher 5.According to Fig. 4 are the retaining pin 7 after engagement in the slot 5 by the molded-on crank surfaces 13 against rotation and fixed by the undercut, which measures by a smaller distance (width across flats) of the sliding surfaces 13 to each other as the shaft 8, 9 in diameter, is formed. The distance between the guide surfaces 13 is about the same size as the inside width of the slots. 5

Im montierten Zustand werden die Haltezapfen 7 der Länge nach von Befestigungselementen durchdrungen. Hier sind als Befetigungselemente Schrauben 16 vorgesehen, die beim Eindrehen in den Haltezapfen 7 die Schaftteile 8 und 9 auseinander drücken und dadurch einen innigen Kraftschluss zwischen den Außenflächen der Schaftteile 8 und 9 und der Innenwandung der Befestigungslöcher 6 herstellen. Da der Haltezapfen 7 vorzugsweise aus Kunststoff hergestellt ist, werden sich die Ränder des Befestigungsloches 6 beim Spreizen außerdem in die Schaftteile 8 und 9 eingraben, so dass zwischen diesen Teilen auch noch ein Formschluss entsteht. Dies sichert eine feste Verbindung.In the assembled state, the retaining pins 7 are penetrated lengthwise by fasteners. Here screws 16 are provided as fastening elements which press the shaft parts 8 and 9 apart when screwed into the retaining pin 7 and thereby produce an intimate adhesion between the outer surfaces of the shaft parts 8 and 9 and the inner wall of the fastening holes 6. Since the retaining pin 7 is preferably made of plastic, the edges of the mounting hole 6 will also dig during spreading in the shaft parts 8 and 9, so that between these parts also creates a positive connection. This ensures a solid connection.

Das Aufspreizen der Schaftteile 8 und 9 des Haltezapfens 7 kann mit unterschiedlichen Schraubenarten (z.B. Schrauben für Kunststoffe, Blechschrauben usw.) oder mit (nicht dargestellten) Einsteckstiften erreicht werden.The spreading of the shaft parts 8 and 9 of the retaining pin 7 can be achieved with different types of screws (for example screws for plastics, sheet metal screws, etc.) or with insertion pins (not shown).
