Description

Die vorliegende Erfindung betrifft ein Hinterlegteil zur Montage an einer Wand, insbesondere zur schaumseitigen Montage an einer Wand eines Kältegerätes, bei dem eine Vorderseite des Hinterlegteiles, die in montiertem Zustand der Wand zugekehrt ist, von einer umlaufenden elastischen Dichtlippe umgeben ist.The present invention relates to a backing part for mounting on a wall, in particular for foam-side mounting on a wall of a refrigerator, in which a front of the backing part, which faces in the assembled state of the wall is surrounded by a circumferential elastic sealing lip.

Herkömmlicherweise ist die Vorderseite eines solchen Hinterlegteiles oft kreisrund oder elliptisch, und die umlaufende Dichtlippe hat die Form eines hohlen Kegelstumpfes, dessen große Grundfläche an der Wand anliegt. Eine Kraft, durch die das Hinterlegteil an der Wand gehalten ist, neigt dazu, die Dichtlippe flachzudrücken, wodurch einerseits der äußere Rand der Dichtlippe elastisch gegen die Wand drückt und so die Dichtwirkung herstellt, zum anderen wird durch die Verformung der Dichtlippe deren äußerer Rand auch in Umfangsrichtung gedehnt. Die Dehnung trägt zu der elastischen Kraft bei, mit der die Dichtlippe gegen die Wand drückt. Bezogen auf die Umfangslänge der Dichtlippe ist die Dehnung gering, so dass sie im Allgemeinen die Elastizitätsgrenze des Materials der Dichtlippe nicht überschreitet.Conventionally, the front side of such a backing part is often circular or elliptical, and the circumferential sealing lip has the shape of a hollow truncated cone whose large base surface rests against the wall. A force by which the backing part is held on the wall tends to flatten the sealing lip, whereby on the one hand, the outer edge of the sealing lip elastically presses against the wall and so produces the sealing effect, on the other hand, by the deformation of the sealing lip whose outer edge also stretched in the circumferential direction. The expansion contributes to the elastic force with which the sealing lip presses against the wall. Relative to the circumferential length of the sealing lip, the elongation is small, so that it generally does not exceed the elastic limit of the material of the sealing lip.

Aus Platzgründen kann es wünschenswert sein, ein Hinterlegteil mit einer eckigen, insbesondere rechteckigen, Vorderseite zu verwenden. Bei einem solchen Hinterlegteil ergibt sich jedoch das Problem, dass ein Abschnitt der Dichtlippe, der sich entlang einer geraden Kante der Vorderseite erstreckt, beim Andrücken gegen die Wand allenfalls elastisch verbogen, aber nicht gedehnt wird, wohingegen an einer Ecke der Vorderseite, an der in unterschiedlichen Richtungen orientierte Abschnitte der Dichtlippe miteinander verbunden sind, eine erhebliche Dehnung zusätzlich zu der Verbiegung auftritt. Dies führt dazu, dass der Widerstand gegen das Flachdrücken an den Ecken der Dichtlippe wesentlich stärker ist als in den geradlinigen Abschnitten, so dass es schwierig ist, einerseits eine ausreichende Verformbarkeit der Dichtlippe an den Ecken und andererseits einen für eine zuverlässige Dichtwirkung ausreichenden Druck der Dichtlippe gegen die Wand an den geradlinigen Abschnitten der Dichtlippe zu gewährleisten. Durch eine Verringerung der Materialstärke der Dichtlippe an den Ecken kann die Verformbarkeit zwar vergleichmäßigt werden, doch werden dadurch an den stark durch Dehnung beanspruchten Ecken Schwachstellen geschaffen, so dass mit einem Reißen der Dichtlippe zu rechnen ist.For reasons of space, it may be desirable to use a backing piece with an angular, in particular rectangular, front side. In such a backing part, however, there is the problem that a portion of the sealing lip, which extends along a straight edge of the front, when bent against the wall at most elastically bent, but not stretched, whereas at a corner of the front, at the in different directions oriented portions of the sealing lip are interconnected, a significant elongation in addition to the bending occurs. As a result, the resistance to flattening at the corners of the sealing lip is substantially greater than in the rectilinear sections, so that it is difficult, on the one hand, sufficient deformability of the sealing lip at the corners and, on the other hand, sufficient pressure of the sealing lip for reliable sealing action to ensure against the wall at the rectilinear sections of the sealing lip. By reducing the material thickness of the sealing lip at the corners of the deformability can indeed be made uniform, but are characterized by the strong by stretching stressed corners created weak points, so that with a tearing of the sealing lip is expected.

Das Dokument JP 11 132 647 A zeigt einen Kühlschrank mit einer Kühlschranktür, welche aus einem vorderen und einem hinteren Türbauteil besteht.The document JP 11 132 647 A shows a refrigerator with a refrigerator door, which consists of a front and a rear door component.

Aufgabe der Erfindung ist daher, ein Hinterlegteil mit einer Dichtlippe zu schaffen, die auch dann eine zuverlässige Dichtung ermöglicht, wenn die Vorderseite Ecken aufweist.The object of the invention is therefore to provide a backing part with a sealing lip, which allows a reliable seal even if the front has corners.

Die Aufgabe wird gelöst durch ein Hinterlegteil, bei dem die Dichtlippe an einer Ecke der Vorderseite wellenförmig verläuft. Durch den wellenförmigen Verlauf wird die Möglichkeit geschaffen, die Dichtlippe an der Ecke längs zu dehnen, ohne dass dafür das Material der Dichtlippe in sich gestreckt werden muss.The object is achieved by a backing part, in which the sealing lip is wavy at a corner of the front. The wave-shaped course creates the opportunity to stretch the sealing lip along the corner without having to stretch the material of the sealing lip in it.

Durch geeignete Wahl der Amplitude der Wellen kann die Kraft, mit der die Dichtlippe pro Längeneinheit gegen die Wand drückt, an den Ecken und in den dazwischen liegenden geradlinigen Abschnitten im Wesentlichen gleich eingestellt werden.By suitable choice of the amplitude of the waves, the force with which the sealing lip presses against the wall per unit length can be set substantially equal at the corners and in the intermediate linear sections.

Vorzugsweise weist die Dichtlippe an der Ecke wenigstens zwei Wellentäler und/oder zwei Wellenkämme auf. Je größer die Zahl der Wellen ist, um so kleiner kann bei gleicher Verformbarkeit deren Amplitude gehalten werden, was ein dichtes Anliegen der Dichtlippe an der Wand über die gesamte Länge der Wellen hinweg begünstigt.The sealing lip preferably has at least two wave troughs and / or two wave crests at the corner. The larger the number of waves is, the smaller can be kept at the same deformability whose amplitude, which favors a close concern of the sealing lip on the wall over the entire length of the waves away.

Um Einbauteile wie etwa einen Schalter, einen Temperatursensor oder dergleichen unterzubringen, ist an der Vorderseite des Hinterlegteiles vorzugsweise eine erste Kammer ausgespart. Um auch im Falle einer unvollständigen Dichtwirkung der Dichtlippe zu verhindern, dass zwischen dieser und der Wand durchsickernder Schaum in die erste Kammer vordringt, ist diese vorzugsweise zentral an der Vorderseite angeordnet und von wenigstens einer Hilfskammer umgeben, in die sich eventuell durchsickernder Schaum ausbreiten kann, so dass er im Allgemeinen verfestigt, bevor er die zentrale erste Kammer erreichen kann.In order to accommodate components such as a switch, a temperature sensor or the like, preferably a first chamber is recessed on the front side of the backing part. In order to prevent even in the case of incomplete sealing effect of the sealing lip that penetrates between this and the wall seeping foam in the first chamber, this is preferably arranged centrally on the front and surrounded by at least one auxiliary chamber into which any leaking foam can spread, so he generally solidifies before he can reach the central first chamber.

Um die Schutzwirkung zu steigern, können entlang einer geraden Linie, die sich von einer Ecke der Vorderseite bis zur ersten Kammer erstreckt, mehrere Hilfskammern angeordnet sein, die im Bedarfsfall nacheinander Schaum aufnehmen können.In order to increase the protective effect, a plurality of auxiliary chambers can be arranged along a straight line which extends from one corner of the front to the first chamber, which can receive foam in succession, if necessary.

Um die Montage eines elektrischen Schalters oder einer anderen elektrischen Komponente in der ersten Kammer zu vereinfachen, sind elektrische Steckkontakte vorzugsweise an einer Bodenseite der ersten Kammer angeordnet. Die elektrische Komponente kann als ein Bestandteil des erfindungsgemäßen Hinterlegteils angesehen werden.In order to simplify the mounting of an electrical switch or other electrical component in the first chamber, electrical plug contacts are preferably arranged on a bottom side of the first chamber. The electrical component may be considered as part of the backing member of the invention.

Vorzugsweise sind die Gestalt der ersten Kammer und eines Körpers der elektrischen Komponente so aneinander angepasst, dass der Körper in der ersten Kammer auf einem Einsteckweg geführt ist und zu den Steckkontakten des Hinterlegteils komplementäre Steckkontakte der elektrischen Komponente auf dem Einsteckweg auf die Steckkontakte des Hinterlegteils ausgerichtet sind. So greifen am Ende des Einsteckwegs die Steckkontakte des Körpers und der ersten Kammer ineinander, was die Montage der elektrischen Komponente beschleunigt und vereinfacht.Preferably, the shape of the first chamber and a body of the electrical component are adapted to each other, that the body is guided in the first chamber on a Einsteckweg and complementary to the plug contacts of the backing part plug contacts of the electrical component are aligned on the insertion of the plug contacts of the backing part , Thus engage the plug contacts of the body and the first chamber into each other at the end of the insertion, which speeds up and simplifies the assembly of the electrical component.

Um die Steckkontakte bzw. die elektrische Komponente elektrisch zu versorgen, muss ein Kabel durch das Hinterlegteil hindurchgeführt sein. Um einen Zutritt von Schaum über die Kabeldurchführung in die erste Kammer zu verhindern, ist das Kabel vorzugsweise mehrfach gekrümmt durch eine Labyrinthkammer geführt, mit der die erste Kammer kommuniziert.In order to supply the plug contacts or the electrical component electrically, a cable must be passed through the backing part. In order to prevent access of foam via the cable feedthrough into the first chamber, the cable is preferably guided in multiple curves through a labyrinth chamber with which the first chamber communicates.

Steckverbinder des Kabels sind vorzugsweise an wenigstens einer Durchgangsöffnung zwischen der ersten Kammer und der Labyrinthkammer formschlüssig platzierbar, so dass sie mit komplementären Steckverbindern der elektrischen Komponente in Eingriff treten können, ohne beim Einstecken der elektrischen Komponente verschoben zu werden.Plug connectors of the cable are preferably form-fittingly placeable on at least one passage opening between the first chamber and the labyrinth chamber, so that they can engage with complementary plug connectors of the electrical component without being displaced upon insertion of the electrical component.

Um die an einer Kabeleintrittsöffnung der Labyrinthkammer eindringende Schaummenge gering zuhalten, ist die Kabeleintrittsöffnung vorzugsweise an einer der Kältegerätewand zugewandten und von dieser beabstandeten Oberfläche des Hinterlegteils gebildet.In order to minimize the amount of foam penetrating a cable inlet opening of the labyrinth chamber, the cable inlet opening is preferably formed on a surface of the backing part facing the refrigeration appliance wall and spaced therefrom.

Besonders bevorzugt ist ein Aufbau, bei dem die erste Kammer und die Hilfskammern in einem vorderen Gehäuse und die Labyrinthkammern in einem hinteren Gehäuse des Hinterlegteils untergebracht sind, wobei die Kabeleintrittsöffnung in dem hinteren Gehäuse einer Rückseite des vorderen Gehäuses gegenüberliegend angeordnet ist. Vorzugsweise ist wenigstens eine Klemmgabel zur Verankerung des Kabels an einer Außenfläche des Hinterlegteils vorgesehen. Eine solche Klemmgabel ermöglicht es zum einen, das Kabel in Höhe der Kabeleintrittsöffnung der Labyrinthkammer zu fixieren und dadurch den Zutritt von Schaum in die Labyrinthkammer zu erschweren. Darüber hinaus bewirkt eine durch Verlegung in den Klemmgabeln vergrößerte Länge des Kabels zwischen den Steckverbindern einerseits und einem in Kontakt mit einem Innenraum des Kältegeräts gekühlten Abschnitt des Kabels andererseits eine Verringerung der Abkühlung, die die Steckverbinder durch Wärmeleitung über das Kabel erfahren, wodurch sich die Gefahr des Niederschlags von Kondenswasser an den Kontakten verringert.Particularly preferred is a structure in which the first chamber and the auxiliary chambers are housed in a front housing and the labyrinth chambers in a rear housing of the backing part, wherein the cable entry opening is arranged in the rear housing opposite to a rear side of the front housing. Preferably, at least one clamping fork is provided for anchoring the cable to an outer surface of the backing part. Such a clamping fork makes it possible, on the one hand, to fix the cable at the height of the cable entry opening of the labyrinth chamber and thereby to make it difficult for foam to enter the labyrinth chamber. In addition, increased by laying in the terminal forks length of the cable between the connectors on the one hand and cooled in contact with an interior of the refrigerator section of the cable on the other hand causes a reduction in the cooling, the connectors experience by heat conduction through the cable, thereby increasing the risk the precipitation of condensation on the contacts decreases.

Vorzugsweise ist eine der Klemmgabeln an einem Halsabschnitt angeordnet, der das vordere und das hintere Gehäuse des Hinterlegteils verbindet.Preferably, one of the terminal forks is disposed on a neck portion connecting the front and rear housings of the backing member.

Um die Platzierung des Kabels und gegebenenfalls seiner Steckverbinder in der Labyrinthkammer zu erleichtern, ist letztere vorzugsweise durch einen Deckel verschließbar.In order to facilitate the placement of the cable and optionally its connector in the labyrinth chamber, the latter is preferably closed by a lid.

Dieser Deckel ist vorzugsweise mit dem hinteren Gehäuse durch ein Folienscharnier verbunden.This cover is preferably connected to the rear housing by a film hinge.

Über einen Durchgang zwischen der Rückwand 9 und dem Längssteg 20 erreicht das Kabel 17 eine Hauptkammer 22 des hinteren Gehäuses 3. An den einzelnen Adern des Kabels 17 vorkonfektionierte Flachsteckbuchsen 23 sind in Aufnahmen der Hauptkammer 22 formschlüssig gegenüber Öffnungen 24 der vorderen Wand 7 gehalten.

The cable 17 is fixed to two Klemmgabeln 18, one of which projects from the neck portion 4 and the other of the rear wall 9 of the rear housing 3. In the interior of the rear housing 3, the cable 16 extends through a labyrinth chamber 19, in which it is forced to a meandering course by alternately projecting transverse webs 21 from a longitudinal web 20 or the side wall 8. Via a passage between the rear wall 9 and the longitudinal web 20, the cable 17 reaches a main chamber 22 of the rear housing 3. On the individual wires of the cable 17 prefabricated blade receptacles 23 are held in receptacles of the main chamber 22 positively against openings 24 of the front wall 7. Of the total of three flat sockets 23 is in the illustration of Fig. 1 one hidden by the cable 16 itself.

Die Montage des Kabels 17 erfolgt, indem zunächst die an dem Kabel 17 vorkonfektionierten Flachsteckbuchsen 23 in die Halterung der Hauptkammer 22 eingesetzt und dann das Kabel 17 in die Labyrinthkammer 19 hineingedrückt wird. Anschließend wird das Kabel 17 in die Klemmgabel 18 des Halsabschnitts 4 eingedrückt und der Deckel 11 auf das Unterteil 5 geklappt und verrastet. Erst danach wird das Kabel 17 auch in die Klemmgabel 18 der Rückwand 9 eingeführt.The cable 17 is assembled by first inserting the blade-type receptacles 23 which are prefabricated on the cable 17 into the holder of the main chamber 22 and then forcing the cable 17 into the labyrinth chamber 19. Subsequently, the cable 17 is pressed into the clamping fork 18 of the neck portion 4 and the lid 11 the lower part 5 folded and locked. Only then is the cable 17 also inserted into the clamping fork 18 of the rear wall 9.

Fig. 2 zeigt eine Frontalansicht des vorderen Gehäuses 2. An der Vorderseite des Gehäuses ist eine zentrale Kammer 25 ausgespart, die sich in den Halsabschnitt 4 hinein erstreckt und deren Boden gleichzeitig die vordere Wand 7 des hinteren Gehäuses 3 ist. Die zentrale Kammer 25 ist umgeben von zwei in der Draufsicht in etwa C-förmigen Hilfskammern 26, an deren Außenseiten sich jeweils mittlere und äußere Hilfskammern 27, 28 anschließen. Die Kammern 25 bis 28 sind in eine ebene Frontseite 29 des vorderen Gehäuses 2 eingetieft, die von einer umlaufenden Dichtlippe 30 umgeben ist. Die Dichtlippe 30 hat vier sich jeweils entlang der geraden Außenkanten der Frontseite 29 erstreckende geradlinige Abschnitte 31. Sie ist in der linken Hälfte der Fig. in einem entspannten Zustand gezeigt; die rechte Hälfte zeigt die Dichtlippe in einem gespannten, flachgedrückten Zustand, der sich bei Anbringung des Hinterlegteils an einer (in der Fig. nicht dargestellten) Wand ergibt. An jeder Ecke, an der zwei Abschnitte 31 aufeinander treffen, hat die Lippe 30 einen in der Frontalansicht der Fig. 2 gewellten Randverlauf mit einer Mehrzahl von Wellentälern und -kämmen. In der Fig. sind exemplarisch an jeder Ecke jeweils zwei Täler 47 und ein dazwischenliegender Kamm 48 dargestellt. Es kommen auch größere Zahlen von Tälern und Kämmen bzw. im einfachsten Fall ein einziges Tal bzw. ein einziger über einen einfach rechteckigen Randverlauf nach außen ausgreifender Kamm in Betracht. Fig. 2 shows a frontal view of the front housing 2. At the front of the housing, a central chamber 25 is recessed, which extends into the neck portion 4 and the bottom of which is at the same time the front wall 7 of the rear housing 3. The central chamber 25 is surrounded by two in the plan view in approximately C-shaped auxiliary chambers 26, on the outer sides of each middle and outer auxiliary chambers 27, 28 connect. The chambers 25 to 28 are recessed in a flat front side 29 of the front housing 2, which is surrounded by a circumferential sealing lip 30. The sealing lip 30 has four straight sections 31 each extending along the straight outer edges of the front side 29. It is shown in a relaxed state in the left half of the figure; the right half shows the sealing lip in a tensioned, flattened state, which results when the backing part is attached to a wall (not shown in the figure). At each corner where two sections 31 meet, the lip 30 has a frontal view of the Fig. 2 wavy edge course with a plurality of troughs and crests. In the figure, two valleys 47 and an intervening comb 48 are shown by way of example at each corner. There are also larger numbers of valleys and ridges or in the simplest case, a single valley or a single on a simple rectangular edge course outstretching out comb into consideration.

Dieser gewellte Randverlauf ermöglicht es der Dichtlippe 30, einem Druck, der das Hinterlegteil 1 gegen eine Wand gepresst hält, auch an den Ecken durch Abflachung nachzugeben, wobei, wie in der rechten Hälfte von Fig. 2 zu sehen, die Amplitude der Wellentäler und -kämme 47, 48 durch die Verformung abnimmt. So kann eine im wesentlichen gleichmäßige Verteilung des Anpressdrucks über die gesamte Länge der Dichtlippe 30 und damit eine gute Dichtwirkung trotz eines stark von der Kreisform abweichenden Querschnitts des vorderen Gehäuses 2 erzielt werden.This corrugated edge course allows the sealing lip 30, a pressure that keeps the backing part 1 pressed against a wall, also yield at the corners by flattening, wherein, as in the right half of Fig. 2 can be seen, the amplitude of the troughs and crests 47, 48 decreases by the deformation. Thus, a substantially uniform distribution of the contact pressure over the entire length of the sealing lip 30 and thus a good sealing effect despite a deviating greatly from the circular cross-section of the front housing 2 can be achieved.

Wenn die Dichtlippe 30 zu stark flach gedrückt ist, kann der gewellte Randverlauf dazu führen, dass der Rand der Dichtlippe an den Ecken nicht auf seiner gesamten Länge anliegt, und es können kleine Lecks zwischen dem Hinterlegteil 1 und der es tragenden Wand auftreten, durch die Schaum zwischen die Wand und das Hinterlegteil 1 gelangt.If the sealing lip 30 is pressed too strongly flat, the corrugated edge profile can cause the edge of the sealing lip at the corners is not applied over its entire length, and there may be small leaks between the backing part 1 and the wall supporting it, through which Foam between the wall and the backing part 1 passes.

Wenn dies geschieht, erreicht der Schaum zunächst eine der beiden äußeren Hilfskammern 28 und expandiert in diese. Durch die Expansionsmöglichkeit verbreitet sich die Front, auf der der Schaum vordringt, und dementsprechend verringert sich die Geschwindigkeit, mit der er vordringt. So kann die Oberfläche des Schaums abbinden und zäh werden, was das Vordringen des Schaums zusätzlich behindert. Wenn das Leck so groß ist, dass die Verzögerung in der äußeren Hilfskammer 28 nicht ausreicht, um den Schaum verfestigen zu lassen, kann dieser die mittlere Hilfskammer 27 und im Notfall eine der C-förmigen inneren Hilfskammern 26 fluten, wodurch der Schaum im allgemeinen ausreichend stark verzögert wird, um ihm Gelegenheit zum Abbinden zu geben und die zentrale Kammer 25 schaumfrei zu halten.When this happens, the foam first reaches one of the two outer auxiliary chambers 28 and expands into them. The possibility of expansion spreads the front on which the foam penetrates, and accordingly reduces the speed with which it advances. Thus, the surface of the foam can set and become tough, which further impedes the advance of the foam. If the leak is so great that the delay in the outer auxiliary chamber 28 is insufficient to solidify the foam, it may flood the central auxiliary chamber 27 and, in an emergency, one of the C-shaped inner auxiliary chambers 26, whereby the foam is generally sufficient is greatly delayed to give him the opportunity to set and keep the central chamber 25 foam-free.

Fig. 3 zeigt schematisch die Montage des Hinterlegteils 1. Als Beispiel für eine Wand, an der das Hinterlegteil 1 montiert werden kann, ist ein aus Blech gebogenes Rahmenprofil 32 im Schnitt dargestellt; das Hinterlegteil 1 und ein von ihm aufzunehmender Schalter 33 sind in Seitenansicht gezeigt. Das Rahmenprofil 32 bildet den frontseitigen, einer Tür zugewandten Abschluss der Decke eines Kältegerätekorpus. In eine Stirnfläche 34 des Rahmenprofils 32 ist ein Fenster 35 geschnitten, das vorgesehen ist, um den Schieber 36 des elektrischen Schalters 33 aufzunehmen. An die Stirnfläche 34 schließt sich nach oben ein horizontaler Schenkel 38 an; am unteren Rand der Stirnfläche 34 ist das Blech des Rahmenprofils 32 zu einer Klammer 39 geformt, die vorgesehen ist, um einen Randbereich eines (nicht dargestellten) aus Kunststoff tiefgezogenen Innenbehälters des Kältegeräts aufzunehmen und einzuklemmen. Fig. 3 schematically shows the mounting of the backing part 1. As an example of a wall on which the backing part 1 can be mounted, a bent sheet metal frame profile 32 is shown in section; the backing part 1 and a switch 33 to be received by it are shown in side view. The frame profile 32 forms the front, a door facing completion of the ceiling of a refrigerator body. In a front surface 34 of the frame profile 32, a window 35 is cut, which is provided to receive the slider 36 of the electric switch 33. At the end face 34 connects to a horizontal leg 38 upwards; at the lower edge of the end face 34, the sheet metal of the frame profile 32 is formed into a bracket 39, which is provided to receive and pinch an edge region of a (not shown) made of plastic deep-drawn inner container of the refrigerator.

Der Schalter 33 hat einen im wesentlichen quaderförmigen Körper 40, dessen Höhe und Breite geringfügig kleiner sind als die entsprechenden Abmessungen der zentralen Kammer 25 des Hinterlegteils 1, so dass der Schalter 37 bequem spielhaltig in die zentrale Kammer 25 eingeschoben werden kann, die andererseits aber groß genug sind, um den Körper 40 in der zentralen Kammer 25 so genau zu führen, dass von der Rückseite des Körpers 40 abstehende Kontaktzungen 41 beim Einschieben des Schalters 33 in die am Boden 7 der zentralen Kammer 25 gebildeten Öffnungen 24 geführt werden und in die dahinter befindlichen Flachsteckbuchsen 23 einrücken. An der Vorderseite des Körpers 40 ist ein umlaufender Bund 42 gebildet, dessen Höhe und Breite eng toleriert mit den entsprechenden Abmessungen der zentralen Kammer 25 übereinstimmen, so dass der Schalter 33, wenn der Bund 42 in die zentrale Kammer 25 eingeschoben ist, in letzterer exakt fixiert ist.The switch 33 has a substantially cuboidal body 40, whose height and width are slightly smaller than the corresponding dimensions of the central chamber 25 of the backing part 1, so that the switch 37 can be easily inserted playful in the central chamber 25, on the other hand, large are enough to guide the body 40 in the central chamber 25 so accurately that protruding from the back of the body 40 contact tongues 41 are guided upon insertion of the switch 33 in the bottom 7 of the central chamber 25 formed openings 24 and in the behind engage located flat sockets 23. On the front of the body 40, a circumferential collar 42 is formed, the height and width of closely tolerated match the corresponding dimensions of the central chamber 25, so that the switch 33, when the collar 42 is inserted into the central chamber 25, is exactly fixed in the latter.

Die Stirnfläche 34 und die Klammer 39 des Rahmenprofils 32 bilden einen Zwickel 43, in den im montierten Zustand ein unterer Abschnitt 31 der Dichtlippe 30 eingreift. Der Abschnitt 31 ist in den Zwickel 43 hineingedrückt gehalten durch eine Mehrzahl von kurzen Rippen 44, die von der Oberseite des vorderen Gehäuses 2 abstehen und unter den horizontalen Schenkel 38 drücken. Wie in der perspektivischen Darstellung der Fig. 1 zu sehen, steht zwischen je zweien der Rippen 44 ein kurzer Zapfen 45 ab, der etwas höher als die Rippen 44 ist. Im montierten Zustand greifen die Zapfen 45 jeweils in ein außerhalb der Schnittebene der Fig. 3 in den horizontalen Schenkel 38 geschnittenes Fenster 46 ein und halten so das Hinterlegteil 1 an dem Rahmenprofil 32 verriegelt und gegen seine Stirnfläche 34 gedrückt, so dass die Dichtlippe 30 auf ihrer gesamten Länge dicht oder schlechtesten Falls mit kleinen Lecks an den Ecken an der Stirnfläche 34 anliegt.The end face 34 and the bracket 39 of the frame profile 32 form a gusset 43, in the assembled state, a lower portion 31 of the sealing lip 30 engages. The portion 31 is held pressed into the gusset 43 by a plurality of short ribs 44 which project from the top of the front housing 2 and press under the horizontal leg 38. As in the perspective view of Fig. 1 can be seen between each two of the ribs 44 from a short pin 45 from which is slightly higher than the ribs 44. In the assembled state, the pins 45 each engage in an outside of the cutting plane of the Fig. 3 in the horizontal leg 38 cut window 46 and thus keep the backing part 1 is locked to the frame profile 32 and pressed against its end face 34, so that the sealing lip 30 over its entire length dense or worst case with small leaks at the corners on the end face 34th is applied.
