Description

Die Erfindung betrifft eine Manschette nach dem Oberbegriff des Patentanspruchs 1 sowie ein Wäschebehandlungsgerät nach dem Oberbegriff des Patentanspruchs 8. Dabei ist im Rahmen der vorliegenden Erfindung unter dem Betriff Wäschebehandlungsgerät sowohl eine klassische Waschmaschine als auch ein sog. Waschtrockner zu verstehen, der die Funktionen einer Waschmaschine und eines Wäschetrockners vereint.The invention relates to a sleeve according to the preamble of claim 1 and a laundry treatment appliance according to the preamble of claim 8. It is understood in the context of the present invention under the term laundry treatment appliance both a classic washing machine and a so-called. Waschtrockner, the functions of a washing machine and a tumble dryer.

Aus der DE 10 2015 216 363 A1 sind eine Manschette und eine Waschmaschine der eingangs genannten Art bekannt, die ein Maschinengehäuse mit einer frontseitigen Beschickungsöffnung und einen in diesem aufgenommenen Laugenbehälter aufweist. Zwischen einer Öffnung des Laugenbehälters und der Beschickungsöffnung ist flüssigkeitsdicht eine schlauchartige Manschette angeordnet, die einen Beschickungskanal bildet. Die Manschette hat an ihrem beschickungsöffnungsseitigen Endbereich eine Dichtlippe mit einer Anlageseite, die an einer Beschickungstür dichtend anliegt, wenn diese in einer die Beschickungsöffnung verschließenden Position ist. Um Beschädigungen durch während der Beschickung nicht korrekt eingelegte und beim Schließen der Beschickungstür zwischen dieser und dem Maschinengehäuse eingeklemmte Wäschestücke zu vermeiden, schlägt die DE 10 2015 216 363 A1 vor, dass ein zwischen der Beschickungstür und gehäuseseitigen Begrenzungswänden gebildeter Türspalt mindestens in einem unteren Teilbereich vergrößert ausgebildet ist.From the DE 10 2015 216 363 A1 are a cuff and a washing machine of the type mentioned above, which has a machine housing with a front-side feed opening and a tub in this recorded. Between an opening of the tub and the charging port, a hose-like sleeve is arranged in liquid-tight manner, which forms a feed channel. The sleeve has at its feed opening side end portion a sealing lip with an abutment side sealingly abutting a loading door when it is in a position closing the loading opening. In order to avoid damage due to incorrectly inserted during the loading and clamped when closing the loading door between this and the machine housing laundry, suggests the DE 10 2015 216 363 A1 in that a door gap formed between the loading door and the housing-side boundary walls is formed enlarged at least in a lower partial area.

Eine Manschette und ein Wäschebehandlungsgerät der eingangs genannten Art gehen auch aus der DE 10 2015 204 327 A1 hervor, die ein Haushaltsgerät zur Pflege von Wäschestücken beschreibt mit einem Gehäuse, einer Beschickungsöffnung in der Gehäusefront, die von einer Beschickungstür verschließbar ist, einem in dem Gehäuse angeordneten Laugenbehälter und einer ringförmigen Dichtungsmanschette, die einen Beschickungskanal zwischen der Beschickungsöffnung und einer zugeordneten Öffnung des Laugenbehälters bildet. Die Manschette hat eine Dichtlippe mit einer Anlageseite, die bei geschlossener Beschickungstür an dieser anliegt. Die Dichtlippe ist an einem unteren Teilumfang ihrer Ringform mit einer Fangschutzstruktur für ein Wäschestück versehen.A cuff and a laundry treatment device of the type mentioned also go from the DE 10 2015 204 327 A1 which describes a domestic appliance for the care of laundry with a housing, a charging opening in the housing front, which is closable by a loading door, a container disposed in the tub and an annular gasket, a feed channel between the feed opening and an associated opening of the tub forms. The cuff has a sealing lip with a plant side, which rests against it with the loading door closed. The sealing lip is provided at a lower part of its circumference ring shape with a catch protection structure for a piece of laundry.

Diese bekannten Manschetten sind darauf gerichtet, durch Beschickungsfehler unvollständig in die Wäschetrommel eingebrachte Wäschestücke und/oder die Manschette selbst vor Beschädigungen zu schützen, wenn fehleingelegte Wäschestücke bei anlaufender Wäschetrommel verdrillen und unter der Dichtlippe weggerissen werden. Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, insbesondere bei sog. Frontlader-Wäschebehandlungsmaschinen eine zuverlässige Türöffnungsfunktion zu realisieren. Dabei soll die Rückhaltkraft, die von der an der Beschickungstür anliegenden Dichtlippe ausgeübt wird, reproduzierbar und möglichst gering sein.These known cuffs are designed to protect garments that are incompletely inserted into the laundry drum due to loading errors, and / or to protect the cuff itself from damage when incorrectly inserted items of laundry are twisted when the laundry drum starts up and are torn away below the sealing lip. In contrast, the object of the present invention is to realize a reliable door opening function, in particular in so-called front loader laundry treatment machines. In this case, the restraining force, which is exerted by the voltage applied to the loading door sealing lip, should be reproducible and minimized.

Die Lösung dieser Aufgabe gelingt erfindungsgemäß hinsichtlich einer Manschette mit einer Manschette mit den Merkmalen des Patentanspruchs 1 und hinsichtlich eines Wäschebehandlungsgeräts mit einem Wäschebehandlungsgerät mit den Merkmalen des Patentanspruchs 8.The solution of this object succeeds according to the invention with respect to a sleeve with a sleeve having the features of patent claim 1 and with regard to a laundry treatment apparatus having a laundry treatment apparatus having the features of patent claim 8.

Demgemäß ist bei einer Manschette bzw. bei einem Wäschebehandlungsgerät der eingangs genannten Art erfindungsgemäß vorgesehen, dass die Anlageseite der Manschette eine Oberflächenstruktur aufweist, die zumindest eine in Umfangsrichtung umlaufende Erhebung umfasst.Accordingly, it is provided according to the invention in a cuff or in a laundry treatment appliance of the type mentioned at the outset that the contact side of the cuff has a surface structure which comprises at least one circumferential survey in the circumferential direction.

Durch die Oberflächenstruktur der Dichtlippe, die beim Schließen der Beschickungstür in Kontakt mit dieser gelangt, wird die auf die Beschickungstür wirkende Rückhaltekraft der Dichtlippe bei weiterhin gewährleisteter Dichtfunktion signifikant verringert. Die Dichtlippe gelangt nämlich nur an separierten und mithin klar definierten Kontaktzonen in Körperkontakt mit der Beschickungstür. Insbesondere, wenn die Beschickungstür einen aus Fensterglas bestehenden, sich nach innen erstreckenden Türkörper umfasst (ein sogenanntes Bullauge), der in Kontakt mit der Dichtlippe gelangt, kann die Rückhaltekraft ohne Erhöhung des Fertigungsaufwandes der Manschette präzise und reproduzierbar eingestellt werden. Dies wird durch die in geschlossenem Zustand der Beschickungstür in axialer Richtung (d.h. im Wesentlichen in Richtung des Beschickungskanals) bestehenden Bereiche eines Körperkontakts (durch die umlaufende Erhebung), d.h. fehlendem Körperkontakt der Anlageseite der Manschette, realisiert. Der sonst übliche flächige Kontaktbereich der Anlageseite wird durch die Erhebung reduziert und gegebenenfalls auf einen Körperkontakt der Erhebung begrenzt.Due to the surface structure of the sealing lip, which comes into contact with it when closing the loading door, the retaining force of the sealing lip acting on the loading door is significantly reduced while the sealing function is still ensured. Namely, the sealing lip only comes into contact with the charging door at separated and thus clearly defined contact zones. In particular, when the loading door comprises an inwardly extending door body made of window glass (a so-called porthole) which comes into contact with the sealing lip, the restraining force can be set precisely and reproducibly without increasing the manufacturing cost of the sleeve. This is determined by the areas of body contact (through the circumferential bump) in the axial direction (i.e., substantially in the direction of the feed channel) when the feed door is closed. lack of body contact the plant side of the cuff, realized. The usual area contact area of the plant side is reduced by the survey and possibly limited to a body contact of the survey.

Besonders bevorzugt ist vorgesehen, dass die Anlageseite der Manschette eine Oberflächenstruktur aufweist, zwei in Umfangsrichtung umlaufende Erhebungen umfasst, die in radialer Richtung durch mindestens eine Vertiefung beabstandet sind. Hierdurch dann vorteilhaft die Dichtfunktion, insbesondere durch eine Labyrinthbildung, sichergestellt werden, wobei dennoch ein flächiger Körperkontakt der Anlageseite der Manschette vermieden werden kann. Dabei müssen die Erhebungen nicht zwingend vollständig umlaufend (d.h. als geschlossene Ringform) ausgebildet sein, solange durch geeignete Maßnahmen - wie z.B. durch in Umfangsrichtung parallel versetzte Erhebungen oder wellen- oder mäanderförmig ausgestaltete Erhebungen - eine ausreichende Dichtfunktion in axialer Richtung sichergestellt ist. Bevorzugt ist zumindest eine bzw. sind mehrere oder alle Erhebungen in geschlossener Ringform gestaltet.It is particularly preferably provided that the contact side of the sleeve has a surface structure, comprising two circumferentially circumferential elevations, which are spaced in the radial direction by at least one recess. In this way, advantageously, the sealing function, in particular by a labyrinth formation, be ensured, yet a flat body contact of the plant side of Cuff can be avoided. In this case, the elevations do not necessarily have to be formed completely circumferentially (ie as a closed ring shape), as long as adequate measures are taken to ensure a sufficient sealing function in the axial direction by means of suitable measures, for example by elevations formed in parallel in the circumferential direction or by waves or meandering elevations. Preferably, at least one or more or all elevations are designed in a closed ring shape.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung, den Unteransprüchen und der Figurenbeschreibung, wobei einzelne Merkmale in Kombination oder einzeln angewendet werden können.Advantageous embodiments of the invention will become apparent from the following description, the dependent claims and the description of the figures, wherein individual features can be used in combination or individually.

Hinsichtlich der Formgebung der Erhebungen bzw. Vertiefungen der Oberflächenstruktur der Anlageseite ist nach einer bevorzugten Fortbildung der Erfindung vorgesehen, dass zumindest eine Erhebung im Profilquerschnitt eine Dreiecksform aufweist, wobei sich die Dreiecksform mit einer Spitze von der Anlageseite weg erstreckt.With regard to the shaping of the elevations or depressions of the surface structure of the plant side is provided according to a preferred development of the invention that at least one elevation in the profile cross-section has a triangular shape, wherein the triangular shape extends with a tip of the plant side away.

Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass zumindest eine Erhebung im Profilquerschnitt eine Rechteckform aufweist.A preferred development of the invention provides that at least one elevation in the profile cross-section has a rectangular shape.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass zumindest eine Erhebung im Profilquerschnitt eine Parabelform aufweist, deren Scheitelpunkt sich von der Anlageseite weg erstreckt.A preferred embodiment of the invention provides that at least one elevation in the profile cross-section has a parabolic shape whose apex extends away from the contact side.

Weiter bevorzugt ist eine Ausgestaltung der Erfindung, nach der zumindest eine Erhebung im Profilquerschnitt ein Haihautprofil aufweist.Further preferred is an embodiment of the invention, according to which at least one elevation in the profile cross section has a sharkskirt profile.

Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass eine Erhebung im Profilquerschnitt eine Sinusform aufweist, deren oberer Scheitelpunkt sich von der Anlageseite weg erstreckt.A further preferred embodiment of the invention provides that a survey in the profile cross section has a sinusoidal shape whose upper vertex extends away from the plant side.

Bei den verschiedenen bevorzugten Profilquerschnitte ist die Anlagefläche gegenüber einer unstrukturierten Oberfläche der Manschette deutlich reduziert, wobei durch Auswahl eines der vorgeschlagenen Profilquerschnittes und durch den geometrischen Abmessungen des Profilquerschnittes die für eine Dichtwirkung erforderliche Kontaktzone und die Rückhaltekraft vorteilhaft genau eingestellt werden kann. Es hat sich gezeigt, dass ein sinunsförmiger Profilquerschnitt ein besonders sanftes Schließen der Beschickungstür ermöglicht. D.h. Die während des Schließens der Beschickungstür aufzuwendende Kraft bzw. deren Änderung über den Schließweg ist gegenüber den anderen Ausführungsformen oder einer Ausführungsform ohne eine erfindungsgemäße Oberflächenstruktur reduziert. Hierbei wird nur der Kraftanteil betrachtet, der durch die Verformung der Anlageseite der Manschette in der Kontaktzone bewirkt wird.In the case of the various preferred profile cross-sections, the contact surface is significantly reduced compared to an unstructured surface of the sleeve, whereby the contact zone and the restraining force required for a sealing effect can advantageously be set precisely by selecting one of the proposed profile cross-section and by the geometric dimensions of the profile cross-section. It has been found that a sinusoidal profile cross-section is a particularly gentle closing of the Loading door allows. That is, the force to be expended during the closing of the loading door or its change via the closing path is reduced compared to the other embodiments or an embodiment without a surface structure according to the invention. Here, only the force component is considered, which is caused by the deformation of the plant side of the sleeve in the contact zone.

Es können auch verschieden profilierte oder ausgestaltete Erhebungen miteinander kombiniert werden, ohne den Gedanken der Erfindung zu verlassen.It is also different profiled or configured surveys combined with each other, without departing from the spirit of the invention.

In the tub 4, a laundry drum 5 is arranged, which is rotatably mounted about a rotation axis 6 and whose front opening 8 is aligned with the feed opening 3, so that a loading into and a removal of laundry from the laundry drum 5 is made possible.

Um dem Laugenbehälter 4 (in Maßen) eine Relativbewegung gegenüber dem Gehäuse 2 zu ermöglichen, ist zwischen der Beschickungsöffnung 3 und der Öffnung 8 eine DichtManschette 9 angeordnet, die hohlzylindrisch ausgeführt ist und die beiden Öffnungen 3 und 8 flüssigkeitsdicht miteinander verbindet. Die Manschette 9 ist dazu mit einem Anschlussbereich 9a mit dem Laugenbehälter 4 und mit ihrem anderen Anschlussbereich 9b mit dem Gehäuse 2 verbunden. Die Manschette 9 bildet somit einen von der Beschickungsöffnung 3 zur Wäschetrommel 5 führenden Beschickungskanal 10. Die Beschickungsöffnung 3 bzw. der Beschickungskanal 10 ist von einer Tür 13, die an dem Gehäuse 2 verschwenkbar befestigt ist, zum Betrieb des Wäschebehandlungsgeräts verschließbar.In order to allow the tub 4 (in dimensions) a relative movement relative to the housing 2, a sealing sleeve 9 is arranged between the feed opening 3 and the opening 8, which is designed as a hollow cylinder and the two openings 3 and 8 connects liquid-tight with each other. For this purpose, the collar 9 is connected to the tub 2 with a connection region 9a and to the housing 2 with its other connection region 9b. The sleeve 9 thus forms a feed channel 3 leading to the laundry drum 5 feed channel 10. Die The feed opening 3 or the feed channel 10 is closed by a door 13 which is pivotally mounted on the housing 2, for operation of the laundry treatment device.

In der in Figur 1 gezeigten geschlossenen Position P der Tür 13 erfolgt eine Abdichtung gegenüber dem Gehäuse 2 durch einen in einen Türrahmen eingelassenen Türkörper 14, der in diesem Ausführungsbeispiel als kegelstumpfartiges Glasbullauge 15 ausgebildet ist. An dessen Wandbereich 15a liegt eine kreisringförmige, nachgiebige und elastisch auslenkbare Dichtlippe 16 der Manschette 9 mit einer Anlageseite 18 umlaufend dichtend an.In the in FIG. 1 shown closed position P of the door 13 is a seal against the housing 2 by a recessed into a door frame door body 14, which is formed in this embodiment as a truncated cone-like glass eye 15. At the wall portion 15a is an annular, resilient and elastically deflectable sealing lip 16 of the sleeve 9 with an abutment side 18 circumferentially sealingly.

Figur 2 zeigt, dass die Anlageseite 18 der Dichtlippe 16 mit einer Oberflächenstruktur 20 versehen ist, die bevorzugt vollständig geschlossene - also in Umfangsrichtung U gesehen kreisförmige - umlaufende Erhebungen 21, 22 aufweist, die als Kontaktflächen, Kontaktflächengipfel oder Kontaktbereiche 23 dienen. In einer alternativen, nicht dargestellten Ausführungsform ist nur eine umlaufende Erhebung 21 oder 22 vorgesehen. In radialer Richtung R ist zwischen den Erhebungen 21, 22 zumindest eine umlaufende Vertiefung 24 vorgesehen, so dass die Erhebungen 21, 22 radial voneinander separiert oder beabstandet sind. In einer alternativen, nicht dargestellten Ausführungsform ist nur eine umlaufende Erhebung 21 oder 22 vorgesehen. FIG. 2 shows that the contact side 18 of the sealing lip 16 is provided with a surface structure 20 which preferably completely closed - so seen in the circumferential direction U circular - circumferential elevations 21, 22, which serve as contact surfaces, contact surface peaks or contact areas 23. In an alternative, not shown embodiment, only a circumferential elevation 21 or 22 is provided. In the radial direction R, at least one circumferential recess 24 is provided between the elevations 21, 22, so that the elevations 21, 22 are radially separated from one another or spaced apart. In an alternative, not shown embodiment, only a circumferential elevation 21 or 22 is provided.

Wie Figur 3 in einem radial in der Dichtlippe 16 verlaufenden Profilquerschnitt Q-Q nach Figur 2 schematisch zeigt, können die umlaufenden Erhebungen 21, 22 Dreiecksform 28, 29 aufweisen. Die Dreiecksformen 28, 29 ragen dabei mit ihrer freien, sich von der Anlageseite 18 weg erstreckenden Dreiecksspitze 28a, 29a nach oben und bei geschlossener Tür 13 (Figur 1) durch entsprechende Auslenkung der Dichtlippe 16 etwa radial in den Beschickungskanal 10 (Figur 1) hinein.As FIG. 3 in a radially extending in the sealing lip 16 profile cross section QQ FIG. 2 schematically shows the circumferential projections 21, 22 triangular shape 28, 29 have. The triangular shapes 28, 29 protrude with their free, from the contact side 18 away extending triangular tip 28a, 29a upwards and with the door closed 13 (FIG. FIG. 1 ) by appropriate deflection of the sealing lip 16 approximately radially into the feed channel 10 (FIG. FIG. 1 ) into it.

Wie Figur 3 in durch verschiedene Schraffuren dargestellte alternative Ausgestaltungen verdeutlicht, können die Profilformen variiert und an die technischen und geometrischen Erfordernisse bedarfsweise angepasst werden, beispielsweise um verschieden großflächige Kontaktbereiche 23 (Figur 1) zu realisieren. Wie angedeutet können dazu z.B. Profile mit weniger spitzwinkliger Dreiecksform 28', 29' mit Dreiecksspitzen 28a', 29a' oder Dreiecksform 28", 29" mit Dreiecksspitzen 28a", 29a" verwendet werden. Es ist auch denkbar, Erhebungen mit verschiedenen Dreiecksformen zu kombinieren.As FIG. 3 illustrated in different hatching alternative embodiments, the profile shapes can be varied and adapted to the technical and geometric requirements, if necessary, for example, to different large-area contact areas 23 (FIG. FIG. 1 ) to realize. As indicated, for example, profiles with less acute-angled triangular shape 28 ', 29' with triangular tips 28a ', 29a' or triangular shape 28 ", 29" with triangular tips 28a ", 29a" can be used. It is also conceivable to combine surveys with different triangular shapes.

Figur 4 zeigt eine Abwandlung der Oberflächenstruktur 20', bei der Erhebungen 21', 22' von im Profilquerschnitt annähernd rechteckigen, kreisringförmigen Fortsätzen 30, 31 mit in geschlossener Position der Tür 13 dem Beschickungskanal 10 zugewandten Stirnseiten 32, 33 gebildet sind. Zwischen den Erhebungen 21', 22' verläuft eine umlaufenden Vertiefung 24'. Die Breite und die Querschnittsfläche der Fortsätze 30, 30', 30"; 31, 31', 31" können je nach Bedarf, Dimension der kooperierenden Komponenten und beispielsweise Materialauswahl für die Manschette variieren. So ist in Figur 4 schematisch dargestellt, dass die Stirnseite 32', 32"; 33', 33" der Fortsätze 30', 30"; 31', 31" statt in der Höhe H auch in geringerer Höhe H' oder H" ausgeführt sein kann. Bevorzugt weisen die Erhebungen wie angedeutet einen leicht trapezförmigen, sich von der Anlageseite 18 weg verjüngenden Querschnitt auf. FIG. 4 shows a modification of the surface structure 20 ', in the elevations 21', 22 'of the profile cross-section approximately rectangular, annular projections 30, 31 are formed in the closed position of the door 13 to the feed channel 10 facing end faces 32, 33. Between the elevations 21 ', 22' extends a circumferential recess 24 '. The width and cross-sectional area of the extensions 30, 30 ', 30 ", 31, 31', 31" may vary as needed, dimension of the cooperating components, and, for example, material selection for the cuff. So is in FIG. 4 shown schematically that the end face 32 ', 32 ", 33', 33" of the extensions 30 ', 30 ";31',31" instead of the height H in a lesser height H 'or H "can be executed the elevations as indicated a slightly trapezoidal, tapered away from the contact side 18 cross-section.

Weitere mögliche Oberflächenstrukturen 20" bzw. 20"' bzw. deren Querschnitte sind in den Figuren 5 und 6 dargestellt. Gemäß Figur 5 können die von einer umlaufenden Vertiefung 24" separierten Profilquerschnitte der Erhebungen 21" und 22" eine Parabelform 35, 36 aufweisen, wobei der Scheitelpunkt 35a, 36a der Parabelform in den Beschickungskanal 10 hineinreichend orientiert ist. Auch hier kann wie vorstehend schon beschrieben je nach Dimensionierung die Höhe der Scheitelpunkte 35a, 35a', 35a" der Parabelform 35, 35', 35" bzw. der Scheitelpunkte 36a, 36a', 36a" der Parabelform 36, 36', 36" je nach Bedarf angepasst werden.Other possible surface structures 20 "or 20"'or their cross-sections are in the FIGS. 5 and 6 shown. According to FIG. 5 For example, the profile cross sections of the elevations 21 "and 22" which are separated by a circumferential recess 24 can have a parabolic shape 35, 36, the apex 35a, 36a of the parabolic shape being oriented in the feed channel 10. Here again, as described above, depending on the dimensioning the height of the vertices 35a, 35a ', 35a "of the parabola 35, 35', 35" and the vertices 36a, 36a ', 36a "of the parabola 36, 36', 36" can be adjusted as needed.

Figur 6 zeigt von einer umlaufenden Vertiefung 24"' separierte Erhebungen 21"', 22"', die im Querschnitt eine sog. Haihautform oder ein Haihautprofil 38, 39 aufweisen. Dieses Profil weist teilweise (linksseitig) einen parabelähnlichen Verlauf auf, der an einem Gipfelpunkt 38a, 39a (bzw. umlaufend an einer Gipfellinie) in eine relativ steil fallende Flanke 40, 41 übergeht. Auch hier können die Höhen der Gipfelpunkte - wie auch zuvor durch verschiedene Schraffierungen angedeutet - Profile definieren, deren Scheitelpunkte 38a', 38a"; 39a', 39a" bedarfsweise tiefer liegend ausgestaltet sind. FIG. 6 shows elevations 21 "', 22"' separated from a circumferential depression 24 "', which have in cross-section a so-called shark shape or a sharkskirt profile 38, 39. This profile has a (parabolic) course in parabolic form, which is at a summit point 38a , 39a (or circumferentially on a summit line) merges into a relatively steep flank 40, 41. Again, the heights of the peaks - as previously indicated by various hatching - define profiles whose vertices 38a ', 38a "; 39a ', 39a "are configured deeper, if necessary.

Figur 7 zeigt von einer umlaufenden Vertiefung 24"" separierte Erhebungen 21"", 22"", die im Querschnitt eine Sinunsform 45, 45', 45", 46, 46', 46" aufweisen. Dieses Profil hat in sowohl Bereich seiner oberen Scheiteilpunkte 45a, 45a', 45a", 46a, 46a', 46a" wie auch im Bereich seiner unteren Scheitelpunkte 45b, 45b', 45b", 46b, 46b', 46b" einen sinusförmigen Verlauf, wobei die oberen Scheitelpunkte 45a, 45a', 45a", 46a, 46a', 46a" in die jeweils benachbarten unteren Scheitelpunkte 45b, 45b', 45b", 46b, 46b', 46b"entsprechend eines sinusförmigen Verlaufs übergehen. Auch hier können die Höhen der oberen Scheitelpunkte 45a, 46a - wie auch zuvor durch verschiedene Schraffierungen angedeutet - Profile definieren, deren obere Scheitelpunkte 45a', 45a", 46a', 46a" bedarfsweise tiefer liegend ausgestaltet sind. FIG. 7 shows from a circumferential recess 24 "" separated elevations 21 "", 22 "", which in cross section a Sinunsform 45, 45 ', 45 ", 46, 46', 46" have. This profile has a sinusoidal course in both its upper vertex points 45a, 45a ', 45a ", 46a, 46a', 46a" and in the region of its lower vertexes 45b, 45b ', 45b ", 46b, 46b', 46b", wherein the upper vertexes 45a, 45a ', 45a ", 46a, 46a', 46a" merge into the respectively adjacent lower vertices 45b, 45b ', 45b ", 46b, 46b', 46b" in accordance with a sinusoidal course. Again, the heights can the upper vertexes 45a, 46a - as previously indicated by different hatching - define profiles whose upper vertexes 45a ', 45a ", 46a', 46a" are configured to be lower, if necessary.

Die vorstehend beispielhaft erläuterten Profilquerschnitte können in verschiedener Kombination auf der Anlageseite 18 der Dichtlippe 16 realisiert und ausgeformt sein. Ferner sind in den Fig. 3 bis 7 sind Profilquerschnitte von jeweils zwei zueinander versetzt auf der Anlageseite 18 der Dichtlippe 16 angeordneten Erhebungen 21, 22 bis 21 "", 22"" dargestellt, jedoch kann auch in alternativen Ausführungsformen nur eine der angeformten Erhebungen einen vorstehend beschriebenen Profilquerschnitt aufweisen, insbesondere bei einer Ausführung mit nur einer umlaufenden Erhebung, oder können mehr als zwei zueinander versetzte angeordnete Erhebungen mit den beschriebenen Profilquerschnitten auf der Anlageseite 18 der Dichtlippe 16 vorgesehen sein.The profile cross sections explained above by way of example can be realized and shaped in various combinations on the contact side 18 of the sealing lip 16. Furthermore, in the Fig. 3 to 7 are profile cross sections of two offset from one another on the contact side 18 of the sealing lip 16 arranged elevations 21, 22 to 21 "", 22 "" shown, however, in alternative embodiments, only one of the molded elevations have a profile cross-section described above, especially in one embodiment with only one circumferential survey, or more than two mutually offset arranged elevations may be provided with the described profile cross-sections on the contact side 18 of the sealing lip 16.
