Abstract

A household appliance, particularly a vacuum cleaner, has a housing of rigid material and formed with at least two interconnected housing parts and a handle that is also made of a rigid material. The household appliance is rendered especially rigid and the risk of losing grip of the handle of the appliance is reduced by integrating the handle into a stiffening element that is disposed at the intersection of the housing parts and by providing the handle with a cover that is made of a softer material.

Description

Die Erfindung betrifft ein Haushaltsgerät, insbesondere einen Staubsauger nach dem Oberbegriff des Anspruch 1. Gattungsbildende Geräte sind beispielsweise aus der US 4,527,302 A bekannt. The invention relates to a household appliance, in particular a vacuum cleaner according to the preamble of claim 1. Generic devices are for example from the US 4,527,302 A known.

Kleinere transportable Haushaltsgeräte, wie beispielsweise Staubsauger, weisen ein Gehäuse auf, an dem ein Handgriff vorgesehen ist, an dem das Gerät erfasst und von einem Ort zu einem anderen Ort getragen werden kann. Der am Gerät vorgesehene Handgriff besteht aus ,zumindest einem ähnlich steifen oder auch harten Material wie das Gehäuse des Gerätes selbst. Dieses Material ist relativ glatt, so dass es beim Erfassen oder Tragen des Gerätes am Handgriff leicht zu einem Abrutschen kommen kann. Außerdem sind die üblicherweise zwei- oder mehrteilig aufgebauten Gehäuse der genannten Geräte an ihrer Gehäusetrennstelle weniger steif und stoßempfindlich. Zur Lösung dessen sieht die EP 1 127 529 A bereits sog. Elastomer-Noppen vor. Smaller portable household appliances, such as vacuum cleaners, have a housing on which a handle is provided, on which the device can be detected and carried from one location to another location. The device provided on the handle consists of, at least a similar stiff or hard material as the housing of the device itself. This material is relatively smooth, so that it can easily come to gripping when grasping or carrying the device on the handle. In addition, the usually two or more parts constructed housing of said devices are less stiff and shock sensitive at their housing separation point. To solve this sees the EP 1 127 529 A already so-called elastomer nubs before.

Der Erfindung liegt die Aufgabe zugrunde, ein Haushaltsgerät, insbesondere einen Staubsauger vorzuschlagen, bei welchem die Nachteile des Standes der Technik mit einfachen konstruktiven Maßnahmen vermieden sind.The invention has for its object to propose a household appliance, in particular a vacuum cleaner, in which the disadvantages of the prior art are avoided with simple constructive measures.

Diese Aufgabe wird durch ein Haushaltsgerät mit den Merkmalen des Anspruchs 1 gelöst. Das erfindungsgemäß vorgesehene Versteifungselement verbindet die Gehäuseteile in einer besonders steifen Verbindung, wobei eine zuverlässige Verbindung von Gehäuse und Handgriff dadurch erzielt wird, dass der Handgriff Bestandteil des Versteifungselements ist. Die Tragesicherheit wird durch einen Überzug aus weicherem Werkstoff erzielt. Weichere Werkstoffe haben von Natur aus eine höhere Haftwirkung, so dass beim Erfassen des mit einem Überzug aus weicherem Material versehenen Handgriffes die Gefahr des Abrutschens wesentlich vermindert ist. Gleichzeitig erfährt die Schnittstelle zwischen den Gehäuseteilen eine deren Stoßempfindlichkeit herabsetzende Versteifung.This object is achieved by a household appliance with the features of claim 1. The inventively provided stiffening element connects the housing parts in a particularly rigid connection, wherein a reliable connection of the housing and the handle is achieved in that the handle is part of the stiffening element. The carrying safety is achieved by a coating of softer material. Softer materials inherently have a higher adhesive effect, so that the risk of slipping off is significantly reduced when detecting the handle provided with a coating of softer material. At the same time, the interface between the housing parts undergoes a stiffening which reduces their shock sensitivity.

Aus fertigungstechnischen Gründen kann es vorteilhaft sein, den Überzug auf den Handgriff im 2-Komponenten-Spritzgußverfahren aufzuspritzen. Damit kann der Überzug bereits während der Herstellung des Verbundbauteils von Versteifungselement und Handgriff in einem Fertigungsschritt kostengünstig und zeitsparend hergestellt werden.For manufacturing reasons, it may be advantageous to spray the coating on the handle in the 2-component injection molding process. Thus, the coating already during the manufacture of the composite component of Reinforcement element and handle in a production step are produced inexpensively and quickly.

Alternativ besteht auch die Möglichkeit den Überzug als gesondertes Teil auszubilden und auf das Versteifungselement aufzubringen. Dies ist dann von Vorteil, wenn wegen der räumlichen Größe des Gerätes ein direktes Aufspritzen zu umständlich oder zu teuer ist. Die Montage eines als gesondertes Teil ausgebildeten Überzuges wird besonders einfach, wenn der Überzug auf den Handgriff aufschnappbar ist. Das Aufschnappen kann beispielsweise durch Rastnasen erfolgen, die an der Innenseite des Überzugs angeformt sind und in Aussparungen am Gehäuse einrasten bzw. einschnappen. In einem späten Fertigungsstadium ist noch Produktionsdifferenzierung möglich.Alternatively, it is also possible to form the coating as a separate part and apply it to the stiffening element. This is advantageous if, because of the physical size of the device, direct spraying is too cumbersome or too expensive. The assembly of a trained as a separate part of the coating is particularly simple when the coating is snapped onto the handle. The snapping can be done for example by locking lugs, which are integrally formed on the inside of the coating and snap into recesses on the housing or snap. Production differentiation is still possible in a late stage of production.

Eine Verbesserung der Haftwirkung des Überzugs lässt sich dadurch erreichen, dass zumindest im Mittenbereich des den Handgriff aufweisenden Versteifungselements an dem Überzug Riefen und/oder Noppen ausgebildet sind. Die Riefen und/oder Noppen bilden eine grobe bzw. raue Struktur, wodurch ein Entgleiten des Handgriffs aus der Hand des Benutzers verhindert ist.An improvement in the adhesive effect of the coating can be achieved in that grooves and / or studs are formed on the coating at least in the middle region of the stiffening element having the handle. The grooves and / or nubs form a rough or rough structure, whereby a slipping of the handle is prevented from the user's hand.

Haushaltsgeräte und hier insbesondere Staubsauger weisen ein aus zwei miteinander verbindbaren Gehäuseteilen bestehendes Gehäuse auf. Bei Staubsaugern ist es je nach Konstruktion des Gehäuses erforderlich, dass die beiden Gehäuseteile möglichst dicht miteinander verbunden sind. Daher ist bei Staubsaugern an der Trennfuge zwischen den beiden Gehäuseteilen eine entsprechende Abdichtung notwendig Erfindungsgemäß ist an dem Überzug mindestens eine in die Trennfuge der miteinander zu verbindenden Gehäuseteile einfügbare Stoßleiste einteilig angeformt. Dies hat den Vorteil, dass auf eine gesonderte gummielastische Dichtung verzichtet werden kann. Solche Dichtungen sind im allgemeinen erforderlich, um den Staubraum nach außen hin staubdicht und geräuscharm abzudichten. Wenn ein erfindungsgemäßer Überzug aus weichem Werkstoff bereits vorgesehen ist, bildet dieser weiche Werkstoff gleichzeitig die elastische Dichtung. Die Dichtung erhält durch den Versteifungsrahmen eine vorgegebene Position und Form, wodurch die Montage der Dichtung erleichtert wird.Domestic appliances and in particular vacuum cleaners have a housing consisting of two housing parts which can be connected to one another. With vacuum cleaners, depending on the construction of the housing, it is necessary for the two housing parts to be connected as tightly as possible. Therefore, in vacuum cleaners at the parting line between the two housing parts a corresponding seal is necessary According to the invention at least one insertable into the parting line of the housing parts to be joined together bumper is integrally formed on the coating. This has the advantage that can be dispensed with a separate rubber-elastic seal. Such seals are generally required to seal the dust chamber to the outside dustproof and low noise. If an inventive coating of soft material is already provided, this soft material simultaneously forms the elastic seal. The seal is given a predetermined position and shape by the stiffening frame, which facilitates the assembly of the seal.

In vorteilhafter Weise können der Überzug und die Dichtung so ausgebildet sein, dass sie gleichzeitig die Funktion einer Stoßleiste übernehmen. Der Überzug kann entlang der Außenkante des Versteifungselements an der Schnittstelle der Gehäusehälften verlaufen und über die Oberfläche des Gehäuses seitlich hervorstehen. Damit wird insbesondere bei fahrbaren Staubsaugern, die während durchzuführender Reinigungsarbeiten häufig weiterbewegt werden müssen und dabei an Gegenständen anstoßen können, ein entsprechender Stoßschutz erreicht. Der fahrbare Staubsauger stößt dabei nur mit der hervorstehenden Stoßleiste an Gegenständen an und das gegenüber der Stoßleiste zurückversetzte Gehäuse bleibt verschont.Advantageously, the coating and the seal can be designed so that they simultaneously assume the function of a bumper. The coating may extend along the outer edge of the stiffening member at the interface of the housing halves and protrude laterally beyond the surface of the housing. Thus, in particular with mobile vacuum cleaners, which must be frequently moved while cleaning work to be carried out and can thereby abut objects, a corresponding impact protection is achieved. The mobile vacuum cleaner abuts only with the protruding bumper to objects and the backbone opposite the bumper case remains spared.

In Verbindung mit dem Versteifungselement ergibt sich für das Gehäuse ein robuster Aufbau. Vorzugsweise weist das Versteifungselement ein aus hartem Werkstoff gebildetes Rahmenteil auf, das an der Schnittstelle zwischen den verbindbaren Gehäuseteilen vorgesehen ist. Indem das Versteifungselement als geschlossener Rahmenzug ausgebildet ist, ergibt sich ein besonders stabiler Aufbau des Versteifungselements. Die Stabilität des Staubsaugergehäuses kann dadurch auf einfache Weise wesentlich erhöht werden.In conjunction with the stiffening element results in a robust construction for the housing. The stiffening element preferably has a frame part formed from hard material, which is provided at the interface between the connectable housing parts. By the stiffening element is designed as a closed Rahmenzug, results in a particularly stable construction of the stiffening element. The stability of the vacuum cleaner housing can be significantly increased in a simple manner.

Das Rahmenteil kann als gesondertes Bauteil ausgebildet sein, das mit einem der Gehäuseteile verbindbar ist. Besonders bei großen Haushaltsgeräten, bzw. Staubsaugern kann es kostengünstiger sein, das Rahmenteil vorzufertigen, beispielsweise im Kunststoff-Spritzgußverfahren und es anschließend an einem Gehäuseteil zu befestigen. Handgriff und Rahmenteil können dagegen einteilig ausgeführt sein. Ein besonders steifer Aufbau ergibt sich, wenn das Rahmenteil als ein einteilig geschlossener Rahmenzug ausgebildet ist, der einen vorbestimmten Teilabschnitt der Gehäusekontur einfasst. Durch die Anordnung des Rahmenzugs entlang der Gehäusekontur insbesondere eines Staubsaugers ist das Rahmenteil möglichst weit außen am Gerät angebracht und dadurch besonders verwindungssteif.The frame part may be formed as a separate component which is connectable to one of the housing parts. Especially with large household appliances, or vacuum cleaners, it may be cheaper to prefabricate the frame part, for example, in the plastic injection molding process and then attach it to a housing part. Handle and frame part, however, can be made in one piece. A particularly rigid structure results when the frame part is formed as a one-piece closed frame train, which encloses a predetermined portion of the housing contour. Due to the arrangement of the Rahmenzugs along the housing contour, in particular a vacuum cleaner, the frame part is mounted as far as possible on the outside of the device and thus particularly torsionally rigid.

Ein gesondertes Dichtungsteil für die Abdichtung des Staubraumes durch den Staubraumdeckel erübrigt sich dadurch, dass an dem Rahmenteil eine umlaufende Dichtung vorgesehen ist, die sich entlang einer Trennfuge zwischen Gehäusekante und Staubaufnahmeraum erstreckt.A separate sealing member for the sealing of the dust chamber through the dust chamber lid is unnecessary in that on the frame part a circumferential Seal is provided which extends along a parting line between the housing edge and dust receiving space.

Der in Fig. 1 gezeigte Staubsauger weist ein Versteifungselement 1 auf. Das Versteifungselement 1 ist zwischen einem unteren Gehäuseteil 3 und einem oberen Gehäuseteil 7 angeordnet. An dem Versteifungselement 1 ist ein bogenförmig gestalteter Handgriff 4 angeformt. Dieser Handgriff 4 ist mit einem Überzug 5 versehen, der aus einem weichelastischen Kunststoff besteht. Im Mittenbereich des Handgriffes 4 ist der Überzug 5 zur Erhöhung der Haftwirkung mit Noppen 6 versehen. Es sind auch andere rutschfeste Oberflächenstrukturen möglich, beispielsweise Rillen oder Riefen, die zur Erhöhung der Haftwirkung dienen. An dem Versteifungselement 1 ist eine Stoßleiste 8 angeformt. Die Stoßleiste 8 ist al elastischer Wulst ausgebildet, der sich aus der Ebene der Gehäuseteile 3 und 7 nach außen hervorhebt. Die Stoßleiste 8 schließt sich an einem Ende des Handgriffs 4 an und läuft entlang des seitlichen Umfangs des Staubsaugers ganz um diesen herum bis sie an einem zweiten Ende des Handgriffs 4 wieder in diesen übergeht. Durch die umlaufende Stoßleiste 8 ist der Staubsauger über seinen gesamten seitlichen Umfang gegen Anstöße geschützt.The vacuum cleaner shown in Fig. 1 comprises a stiffening element 1. The stiffening element 1 is arranged between a lower housing part 3 and an upper housing part 7. On the stiffening element 1 an arcuately shaped handle 4 is formed. This handle 4 is provided with a coating 5, which consists of a soft elastic plastic. In the middle region of the handle 4 of the coating 5 is provided to increase the adhesion with nubs 6. There are also other non-slip surface structures possible, such as grooves or grooves, which serve to increase the adhesive effect. At the stiffening element 1 a bumper 8 is formed. The bumper 8 is formed as an elastic bead, which stands out from the plane of the housing parts 3 and 7 to the outside. The bumper 8 connects to one end of the handle 4 and runs along the lateral periphery of the vacuum cleaner all around it until it merges at a second end of the handle 4 again in this. Due to the circumferential bumper 8 of the vacuum cleaner is protected over its entire lateral extent against impacts.

Die Fig. 2 zeigt das Versteifungselement 1 des Staubsaugers aus Figur 1. Das Versteifungselement 1 umfasst ein zentrales rahmenförmiges Rahmenteil 11 aus hartem Werkstoff. Das Rahmenteil 11 weist an seinen vier Eckbereichen je ein Schraubloch 2 auf, durch die das Rahmenteil 11 an dem unteren Gehäuseteil 3 mittels nicht dargestellter Schrauben befestigt wird. Entlang der Innenkante des Rahmenteils 11 ist eine weichelastische Dichtung 10 an das Rahmenteil 11 angeformt. Die Dichtung 10a liegt im eingebauten Zustand an einem Gehäusedeckel des Staubraums des Staubsaugers druckdicht an. Entlang der Außenkante des Rahmenteils 11 ist eine weichelastische Stoßleiste 8 an das Rahmenteil 11 angeformt. Die Stoßleiste 8 erstreckt sich nicht nur entlang der Außenkante des Rahmenteils 11, sondern ist über das Rahmenteil 11 hinweg derart verlängert, dass im eingebauten Zustand des Versteifungselements 1 die Stoßleiste 8 über den gesamten seitlichen Umfang des Staubsaugers verläuft. Die Stoßleiste 8 ist also nicht nur an der linken und rechten seitlichen Außenkante des Rahmenteils 11 angeformt, sondern umfasst auch zwei freie Enden 9a und 9b. Die freien Ende 9a und 9b laufen im eingebauten Zustand entlang der Trennfuge zwischen den Gehäusehälften, die den Motorraum 20 einschließen. Die freien Enden 9a und 9b dienen nicht nur als Stoßleiste 8, sondern bilden gleichzeitig auch die Dichtung 10b, welche den Motorraum verschließt. An der den freien Enden 9a und 9b gegenüberliegenden Seite des Rahmenteils 11 geht die Stoßleiste 8 fließend in den Handgriff 4 über. An der Außenseite des Handgriffs 4 ist durch die übergehende Stoßleiste 8 ein weichelastischer Überzug 5 gebildet, der zum einen auch als Stoßleiste dient und gleichzeitig auch als weicher, rutschfester Griffbereich dient. An der Innenseite des Handgriffs 4 ist ein zusätzlicher weichelastischer Abschnitt angeformt, der mit Noppen 6 versehen ist. Die Noppen 6 erhöhen die Hafteigenschaften, wodurch ein Entgleiten des Staubsaugers aus der Hand des Benutzers verhindert ist.FIG. 2 shows the stiffening element 1 of the vacuum cleaner from FIG. 1. The stiffening element 1 comprises a central frame-shaped frame part 11 made of hard material. The frame part 11 has at its four corner regions depending on a screw hole 2, by which the frame part 11 is fixed to the lower housing part 3 by means not shown screws. Along the inner edge of the frame part 11, a soft elastic seal 10 is integrally formed on the frame part 11. The seal 10a is in the installed state pressure-tight against a housing cover of the dust chamber of the vacuum cleaner. Along the outer edge of the frame part 11, a soft elastic bumper 8 is formed on the frame part 11. The bumper strip 8 not only extends along the outer edge of the frame part 11, but is extended over the frame part 11 away such that in the installed state of the stiffening element 1, the bumper strip 8 extends over the entire lateral circumference of the vacuum cleaner. The bumper 8 is therefore not only formed on the left and right lateral outer edge of the frame part 11, but also includes two free ends 9 a and 9 b. The free ends 9 a and 9 b run in the installed state along the parting line between the housing halves, which enclose the engine compartment 20. The free ends 9a and 9b not only serve as a bumper 8, but at the same time also form the seal 10b, which closes the engine compartment. At the free ends 9a and 9b opposite side of the frame part 11, the bumper 8 is flowing into the handle 4 over. On the outside of the handle 4 is formed by the passing bumper 8, a soft elastic coating 5, which also serves as a bumper and at the same time serves as a soft, non-slip grip area. On the inside of the handle 4, an additional soft elastic portion is formed, which is provided with nubs 6. The nubs 6 increase the Adhesive properties, whereby a slipping of the vacuum cleaner from the user's hand is prevented.

In der Figur 3 ist der Handgriff 4 in einer Schnittansicht A-A gezeigt. Das Versteifungselement 1 aus hartem Werkstoff ist über das Rahmenteil 11 hinaus bogenförmig verlängert, wodurch sich ein D-förmiger Rahmenabschnitt 12 ergibt, der an das Rahmenteil 11 angrenzt. Dieser Rahmenabschnitt 12 bildet eine Grundstruktur des Handgriffs 4. An den Rahmenabschnitt 12 aus hartem Werkstoff ist an dessen nach unten offenem Hohlraum eine weichelastische Füllung 13 eingeformt. An der der weichelastischen Füllung 13 gegenüberliegenden Seite des Rahmenabschnitts 12 ist ein Überzug 5 aufgebracht. Der Überzug 5 ist aus weichelastischem Werkstoff und weist Noppen 6 auf, durch die der Handgriff rutschfest gegriffen werden kann.In the figure 3, the handle 4 is shown in a sectional view A-A. The stiffening element 1 made of hard material is extended arcuately beyond the frame part 11, resulting in a D-shaped frame portion 12 which adjoins the frame part 11. This frame portion 12 forms a basic structure of the handle 4. At the frame portion 12 made of hard material at its downwardly open cavity a soft elastic filling 13 is formed. At the soft elastic filling 13 opposite side of the frame portion 12, a coating 5 is applied. The cover 5 is made of soft elastic material and has knobs 6, through which the handle can be gripped non-slip.

In der Figur 4 ist das Rahmenteil 11 in einer Schnittansicht B-B im eingebauten Zustand gezeigt. Auf der oberen Seite des Rahmenteils 11 ist ein Material aus weichelastischem Werkstoff angeformt. An der Außenseite wird durch dieses weichelastische Material die Stoßleiste 8 gebildet. Diese Stoßleiste 8 weist annähernd D-förmigen Querschnitt auf. Durch die D-Form ergibt sich ein progressives Anstoßverhalten, d.h. mit zunehmender Eindringtiefe bei einem Anstoß an die D-förmige Stoßleiste 8 nimmt die Elastizität ab und die Stoßleiste bietet bei härteren Anstößen auch einen erhöhten Widerstand gegen das Anstoßen. An der Innenseite des Rahmenteils 11 ist die Dichtung 10 angeformt. Die Dichtung 10 besteht aus dem selben Werkstoff wie die Stoßleiste 8 und ist mit dieser einstückig an das Rahmenteil 11 angeformt. Die Dichtung 10 weist eine nach oben ragende Dichtlippe 14 auf, die über den gesamten Umfang des Rahmenteils 11 umläuft. Im eingebauten Zustand liegt die Dichtlippe 14 an einer Gehäusekante 15 eines Staubraumdeckels 16 an. Die Dichtung 10 weist an ihrem unteren Ende zwei parallel verlaufende entlang des Rahmenteils 11 umlaufende Stege 17a und 17b auf. Diese Stege 17a und 17b bilden eine Führungsnut in die eine Gehäusewand 18 des unteren Gehäuseteils 3 im eingebauten Zustand eingefügt ist. Die Gehäusewand 18 bildet dadurch eine stabile Aufnahme und ein Widerlager zur Führung der Dichtlippe 14.In the figure 4, the frame part 11 is shown in a sectional view BB in the installed state. On the upper side of the frame part 11, a material of soft elastic material is formed. On the outside, the bumper 8 is formed by this soft elastic material. This bumper 8 has approximately D-shaped cross-section. Due to the D-shape results in a progressive abutment behavior, ie with increasing penetration depth at an impact on the D-shaped bumper strip 8 decreases the elasticity and the bumper provides for harder impacts also increased resistance to the abutment. On the inside of the frame part 11, the seal 10 is formed. The seal 10 is made of the same material as the bumper strip 8 and is formed integrally therewith to the frame part 11. The seal 10 has an upwardly projecting sealing lip 14, which rotates over the entire circumference of the frame part 11. When installed, the sealing lip 14 bears against a housing edge 15 of a dust compartment cover 16. The seal 10 has at its lower end two parallel extending along the frame member 11 ridges 17a and 17b. These webs 17a and 17b form a guide groove into which a housing wall 18 of the lower housing part 3 is inserted in the installed state. The housing wall 18 thereby forms a stable receptacle and an abutment for guiding the sealing lip fourteenth

In der Figur 5 ist das Rahmenteil 11 in einer Schnittansicht C-C im eingebauten Zustand gezeigt. An der Innenseite des Rahmenteils 11 ist die Dichtung 10 angeformt. Die Dichtung 10 besteht aus dem selben Werkstoff wie die Stoßleiste 8 und ist mit dieser einstückig an das Rahmenteil 11 angeformt. Die Dichtung 10 weist eine nach oben ragende Dichtlippe 14 auf, die über den gesamten Umfang des Rahmenteils 11 umläuft. Im eingebauten Zustand liegt die Dichtlippe 14 an einer Gehäusekante 15 eines Staubraumdeckels 16 an. Die Dichtung 10 weist an ihrem unteren Ende zwei parallel verlaufende entlang des Rahmenteils 11 umlaufende Stege 17a und 17b auf. Diese Stege 17a und 17b bilden eine Führungsnut in die eine Gehäusewand 18 des unteren Gehäuseteils 3 im eingebauten Zustand eingefügt ist. Die Gehäusewand 18 bildet dadurch auch in dem Bereich zwischen Staubraum 19 und Motorraum 20 eine stabile Aufnahme und ein Widerlager zur Führung der Dichtlippe 14. In dem Bereich des Rahmenteils 11 welcher zwischen Staubraum 19 und Motorraum 20 liegt, erübrigt sich das Anformen einer Stoßleiste 8. Um das Versteifungselement 1 besonders in diesem Bereich an der unteren Gehäusehälfte 3 stabil zu fixieren ist an den Querschnitt des Rahmenteils 11 ein harter Federsteg 21 angeformt, der in eine zugeordnete Nut 22 in der unteren Gehäusehälfte 3 eingreift. Dadurch ist das Rahmenteil 11 zusätzlich im Bereich zwischen Staubraum 19 und Motorraum 20 in seiner Lage fixiert.In the figure 5, the frame part 11 is shown in a sectional view C-C in the installed state. On the inside of the frame part 11, the seal 10 is formed. The seal 10 is made of the same material as the bumper strip 8 and is formed integrally therewith to the frame part 11. The seal 10 has an upwardly projecting sealing lip 14, which rotates over the entire circumference of the frame part 11. When installed, the sealing lip 14 bears against a housing edge 15 of a dust compartment cover 16. The seal 10 has at its lower end two parallel extending along the frame member 11 ridges 17a and 17b. These webs 17a and 17b form a guide groove into which a housing wall 18 of the lower housing part 3 is inserted in the installed state. The housing wall 18 thereby also forms a stable receptacle and an abutment for guiding the sealing lip 14 in the region between the dust chamber 19 and the engine compartment 20. In the region of the frame part 11 which lies between the dust chamber 19 and the engine compartment 20, molding of a protective strip 8 is unnecessary. To stably fix the stiffening element 1 to the lower half 3 of the housing, particularly in this area, a hard spring bar 21 is integrally formed on the cross section of the frame part 11 and engages in an associated groove 22 in the lower half 3 of the housing. As a result, the frame part 11 is additionally fixed in the area between the dust chamber 19 and the engine compartment 20 in its position.

In der Figur 6 ist das Rahmenteil 11 in einer Schnittansicht D-D im eingebauten Zustand gezeigt. In diesem Abschnitt, welcher sich im Bereich der freien Enden 9a, 9b befindet ist der weichelastische Werkstoff als Stoßleiste 8 ausgebildet. Die obere Gehäusehälfte 7 und die untere Gehäusehälfte 3 sind in diesem Bereich unlösbar miteinander verbunden, d.h. diese beiden Gehäusehälften sind während des Gebrauchs nicht trennbar. Daher erübrigt sich in diesem Bereich die Ausbildung einer innenliegenden Dichtlippe. In diesem Abschnitt weist die Stoßleiste 8 jedoch einen Stegabschnitt 22 auf, der zusammen mit der Stoßleiste 8 eine Nut 23 einschließt. In die Nut 23 greift die Gehäusewand 18 der unteren Gehäusehälfte 3 ein. Durch diese gesteckte Verbindung erhalten die weichelastischen freien Enden 9a, 9b eine Lagestabilisierung während der Montage und die Stoßleiste 8 ist in diesem Abschnitt zwischen oberer Gehäusehälfte 7 und unterer Gehäusehälfte 3 eingespannt.In the figure 6, the frame part 11 is shown in a sectional view D-D in the installed state. In this section, which is located in the region of the free ends 9a, 9b, the soft elastic material is designed as a bumper strip 8. The upper half of the housing 7 and the lower half of the housing 3 are inseparably connected to each other in this area, i. these two housing halves are inseparable during use. Therefore, the formation of an inner sealing lip is unnecessary in this area. In this section, the bumper 8, however, a web portion 22, which includes a groove 23 together with the bumper 8. In the groove 23, the housing wall 18 of the lower housing half 3 engages. Through this mating connection, the soft elastic free ends 9a, 9b receive a position stabilization during assembly and the bumper 8 is clamped in this section between the upper half of the housing 7 and the lower half of the housing 3.
