The sealing body (1) is movable by means of an actuating device (4) which is operative upon closing the door (T). Arranged preferably on both sides of the sealing member (1) is in each case one resilient scraping or sliding strip (6A, 6B) which extends in the longitudinal direction of the sealing body (1) and seals off the air gap (17) present at the side of the sealing body (1). The scraping or sliding strips (6A, 6B) are fixed to the door or the guide rail (2) and project with a flat lip part (16), at least in the uppermost working position of the sealing body (1), substantially horizontally or downwardly inclined relative to the sealing strip (5), or are designed as a brush. The flat lip parts (16) or the brush hairs bear sealingly on the sealing strip (5) with or close to their free edges (18). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Dichtungsanordnung für eine, insbesondere schwellenlose, Tür der dem Oberbegriff des Anspruchs 1 entsprechenden Art.The invention relates to a sealing arrangement for a, in particular threshold-free, door of the type corresponding to the preamble of claim 1.

Bei derartigen Dichtungsanordnungen ist notwendiger­weise ein Luftspalt zwischen dem auf- und abbewegbaren Dich­tungskörper und der den Dichtungskörper führenden Führungs­schiene über die gesamte Länge der Dichtungsanordnung vor­handen. Der Dichtungskörper besteht meist aus einem Dich­tungsträger aus Profilmaterial und einer daran befestigten elastischen Dichtungsleiste, die auf dem Boden zur Anlage kommt. Üblicherweise befinden sich derartige Luftspalte an beiden Seiten des Dichtungskörpers. Am Fußboden befindlicher Staub und Schmutz würde in Verbindung mit dem beim Bewegen der Tür unter der Türblattunterkante entstehenden Luftzug schnell zu einer unzuträglichen Verschmutzung der Betäti­gungsvorrichtung zum Heben und Senken des Dichtungskörpers führen. Dies würde die erforderliche Leichtgängigkeit des Dichtungskörpers nach kurzer Gebrauchszeit zunichte machen - umso mehr, als in den Luftspalt eintretende Nässe zur frühzeitigen Korrosion metallischer Bauteile führt.In such sealing arrangements, an air gap is necessarily present between the sealing body which can be moved up and down and the guide rail guiding the sealing body over the entire length of the sealing arrangement. The sealing body usually consists of a sealing carrier made of profile material and an attached elastic sealing strip, which comes to rest on the floor. Such air gaps are usually located on both sides of the sealing body. Dust and dirt on the floor, in connection with the air draft created when moving the door under the lower edge of the door leaf, would quickly lead to inadmissible contamination of the actuating device for lifting and lowering the sealing body. This would negate the required smoothness of the sealing body after a short period of use - all the more as moisture entering the air gap leads to premature corrosion of metallic components.

Bei einer gattungsgemäßen Dichtungsanordnung, wie sie u. a. in der US Lit. : Progressive Architecture 2:77, S. 46" Sound investment: Zero's new door bottoms" und der DE-A2-­32 37 524 beschrieben ist, werden diese Luftspalte von lang­gestreckten Schabe- oder Gleit-Leisten verschlossen, welche an dem Dichtungskörper festgelegt sind und mit diesem auf­ und abbewegt werden. Dabei erstreckt sich der den Luftspalt verschließende Teil der Schabe- oder Gleit-Leiste mit einer sehr großen Neigung, wie bei der US Lit. , oder mit einer sehr geringfügigen Neigung gegenüber der Vertikalrichtung. Gemäß der DE-A2-32 37 524 erstreckt sich die Schabe- oder Gleit-­Leiste über etwa zwei Drittel der Höhe des Dichtungskörpers von der oberen Kante des Dichtungskörpers nach unten und außen, wobei die als Dichtungslippe ausgestaltete freie Kan­te der Schabe- oder Gleit-Leiste an der Innenseite der ver­tikalen Schenkel der im Querschnitt U-förmigen Führungs­schiene mit einem sehr spitzen Winkel anliegt. Diese Anord­nung hat u. a. den Nachteil relativ großer Reibungskräfte zwischen der Dichtungsleiste und der Führungsschiene, so daß die Leichtgängigkeit des Dichtungskörpers unzuträglich behindert wird. Diese Reibung führt auch zu einem schnel­len Verschleiß der Dichtungslippe. Insbesondere aber besteht bei der bekannten Ausführungsform ein sehr tiefer, schmaler Spalt zwischen der Außenseite des Dichtungskörpers und der Innenseite der Dichtlippe. Der Spalt kann von Schmutz aus­gefüllt werden, wodurch die Beweglichkeit der Dichtlippe aufgehoben und die Reibung erhöht werden. Demgegenüber be­steht bei der US Lit. der Nachteil der Gleitleiste u. a. darin, daß sie bei Wechsel der Bewegungsrichtung umklappen muß und dieses Umklappen energiezehrend ist.With a generic sealing arrangement, as described, inter alia, in US Lit.: Progressive Architecture 2:77, p. 46 "Sound investment: Zero's new door bottoms" and DE-A2-32 37 524, these air gaps are formed by elongated cockroaches - or slide strips closed, which are fixed to the sealing body and with this and be moved. The part of the scraping or sliding bar which closes the air gap extends with a very large inclination, as in the US lit., or with a very slight inclination with respect to the vertical direction. According to DE-A2-32 37 524, the scraping or sliding strip extends downwards and outwards from the upper edge of the sealing body over approximately two thirds of the height of the sealing body, the free edge of the scraping or sliding configured as a sealing lip Bar on the inside of the vertical legs of the cross-sectionally U-shaped guide rail lies at a very acute angle. This arrangement has, inter alia, the disadvantage of relatively large frictional forces between the sealing strip and the guide rail, so that the smooth movement of the sealing body is unacceptably hindered. This friction also leads to rapid wear of the sealing lip. In particular, however, in the known embodiment there is a very deep, narrow gap between the outside of the sealing body and the inside of the sealing lip. The gap can be filled with dirt, which eliminates the mobility of the sealing lip and increases the friction. In contrast, the disadvantage of the slide bar in US lit. is, among other things, that it must fold over when the direction of movement changes and this fold over is energy-consuming.

Um eine besonders gute Leichtgängigkeit des Dichtungs­körpers bei bestmöglicher Verschleißarmut zu realisieren, ist vorgeschlagen (EP-B1 138 771 und DE-C2-30 12 660) und mit Erfolg praktisch angewendet worden, daß die Luftspalte durch im Querschnitt U- bzw. C-förmige Banddichtungen aus elastischem Material, sogenannte Rolldichtungen, verschlos­sen werden, wobei der eine nach unten weisende Bandschenkel am Führungsprofil und der andere nach unten weisende Band­schenkel am Dichtungskörper befestigt sind. Dadurch findet bei der Höhenverstellung des Dichtungskörpers ein Abrollen des elastischen Bandes im Bereich des U-Joches statt. Diese wegen des Fehlens einer Dichtungslippe nicht gattungsgemäße Dichtungsanordnung hat aber den Nachteil, wegen der beiden neben dem Dichtungskörper befindlichen im Querschnitt U-­förmigen Banddichtungen in Breitenrichtung relativ viel Platz zu beanspruchen. Das Rückstellvermögen derart getrenn­ter Profile setzt dem Absenkvorgang einen nicht unerheblichen Widerstand entgegen, so daß eine entsprechend hohe Auslöse­kraft erforderlich ist. Ein weiterer Nachteil dieser Dich­tungsbänder besteht in der Lageveränderung zwischen Dich­tungskörper und Führungsschiene beim Schließen und Öffnen der Tür, weil das dadurch erzwungene Walken des Dichtungs­bandes zum schnellen Verschleiß des Dichtungsbandes führen kann; außerdem ist die Herstellung und die Montage des Dich­tungsbandes aufwendig und ist das Dichtungsband bei der De­montage des Dichtungskörpers hinderlich.In order to achieve particularly good smoothness of the sealing body with the best possible low wear, it has been proposed (EP-B1 138 771 and DE-C2-30 12 660) and has been successfully used in practice that the air gaps are U-shaped or C-shaped in cross-section Band seals made of elastic material, so-called roll seals, are closed, one downward pointing band leg being fastened to the guide profile and the other downward pointing band leg being fastened to the sealing body. As a result, when the sealing body is adjusted in height, the elastic band rolls off in the region of the U-yoke. These due to the lack of a sealing lip, however, a generic sealing arrangement has the disadvantage of taking up a relatively large amount of space in the width direction because of the two band seals which are U-shaped in cross section and located next to the sealing body. The resilience of such separate profiles opposes the lowering process with a not inconsiderable resistance, so that a correspondingly high release force is required. Another disadvantage of these sealing tapes is the change in position between the sealing body and the guide rail when the door is being closed and opened, because the consequent flexing of the sealing tape can lead to rapid wear of the sealing tape; in addition, the manufacture and assembly of the sealing tape is complex and the sealing tape is a hindrance when dismantling the sealing body.

Davon ausgehend liegt der Erfindung die Aufgabe zu­grunde, bei einer gattungsgemäßen Dichtungsanordnung eine verbesserte Abdichtung und Leichtgängigkeit des Dichtungs­körpers zu ermöglichen.Proceeding from this, the object of the invention is to enable improved sealing and smooth movement of the sealing body in a generic sealing arrangement.

Diese Aufgabe wird durch die in Ansprüchen 1, 2 und 3 wiedergegebenen alternativen technischen Lehren gelöst, die auf dem Grundgedanken basieren, die mindestens eine Schabe- oder Gleit-Leiste mit einer Längskante an oder nahe der Türblattunterkante oder an der Führungsschiene der Dich­tungsanordnung, insbesondere starr, zu befestigen.This object is achieved by the alternative technical teachings reproduced in claims 1, 2 and 3, which are based on the basic idea that at least one scraping or sliding strip with a longitudinal edge on or near the lower edge of the door leaf or on the guide rail of the sealing arrangement, in particular rigid , to fix.

Die Auf- und Abbewegung des Dichtungskörpers wird durch die frei vorkragenden und sich bei Verlagerungen der Anlagefläche um eine Längsachse verbiegenden oder als Bürste ausgestalteten, nur leicht anliegenden Schabe- oder Gleit-­Leiste nur vergleichsweise geringfügig behindert. Die Scha­be- oder Gleit-Leiste der erfindungsgemäßen Ausbildungen und Anordnungen ermöglichen eine besonders geringe Baubreite und Bauhöhe der Gesamtdichtungsanordnung. Trotz der geringen Kontaktfläche zwischen dem Oichtungskörper einerseits und der Schabe- oder Gleit-Leiste andererseits wird eine sehr zufrie­denstellende Abdichtung der Luftspalte gegen das Eindringen von Verschmutzungen und Nässe erreicht. Insbesondere verstär­ken sich bei den Ausführungsformen nach Anspruch 1 bei einem Druck von unten Anlage und Abdichtung; bei diesen Ausfüh­rungsformen bilden die als Dichtlippen ausgestalteten Scha­be- oder Gleit-Leisten und die Unterseite der Dichtungsleiste eine im wesentlichen in einer Höhe verlaufende geschlossene untere Begrenzung der Dichtungsanordnung.The up and down movement of the sealing body is only comparatively slightly hampered by the freely projecting cantilever bar, which bends when the contact surface is shifted about a longitudinal axis or is designed as a brush, and is only slightly in contact. The scraping or sliding bar of the designs and arrangements according to the invention enable a particularly small overall width and overall height of the overall sealing arrangement. Despite the small contact area between the sealing body on the one hand and the On the other hand, a scraping or sliding bar provides a very satisfactory sealing of the air gaps against the ingress of dirt and moisture. In particular, in the embodiments according to claim 1, pressure and sealing increase the contact and sealing; In these embodiments, the scraping or sliding strips designed as sealing lips and the underside of the sealing strip form a closed lower boundary of the sealing arrangement which runs essentially at a height.

Der Montageaufwand für die Schabe- oder Gleit-Leisten, welche auch nachgerüstet und im Bedarfsfalle leicht ausge­wechselt werden können, ist gering; insbesondere braucht bei dieser Arbeit die Dichtungsleiste nicht entfernt zu werden. Wenn sich der Dichtungskörper nahe der Offenstellung befin­det, die Kraft der Rückstellfeder also schon verringert ist, wird durch die Ausführungsformen der Schabe- oder Gleit-­Leiste nach Anspruch 1 der letzte Rest des Hubweges erleich­tert, da die Schabe- oder Gleit-Leiste dann eine zusätzliche Federkraft beitragen.The assembly effort for the scraping or gliding strips, which can also be retrofitted and easily replaced if necessary, is low; in particular, the sealing strip does not need to be removed during this work. If the sealing body is close to the open position, so the force of the return spring is already reduced, the last rest of the stroke path is made easier by the embodiments of the scraping or sliding strip according to claim 1, since the scraping or sliding strip then has an additional one Contribute spring force.

Sie sind in entgegengesetzter Anordnung, d. h. mit nach unten offenem "U" bei der Führungsschiene 2 und mit nach oben offenem "U" bei dem Dichtungsträger 3, unter Ausbildung eines Hohlraumes 7 zur Aufnahme der Betätigungs­vorrichtung 4 ineinandergefügt und gegeneinander höhenver­stellbar.The guide rail profile and the seal carrier profile are preferably essentially of U-shaped cross section. They are in opposite order, i.e. H. with a downwardly open "U" in the guide rail 2 and with an upwardly open "U" in the seal carrier 3, with the formation of a cavity 7 for accommodating the actuating device 4, and mutually adjustable in height.

Das Führungsschienenprofil weist an der Innenseite des U-Bogens hakenförmige Profilstege 8A und 8B zur Halterung und Positionierung der Betätigungsvorrichtung auf. Diese Profilstege können auch als oberer Höhenanschlag für den Dichtungskörper 3 dienen.The guide rail profile has hook-shaped profile webs 8A and 8B on the inside of the U-bend for holding and positioning the actuating device. These profile webs can also serve as an upper height stop for the sealing body 3.

An den freien U-Schenkelenden der Führungsschiene 2 ist jeweils eine Schabe- oder Gleit-Leiste 6A bzw. 6B be­festigt. Vorteilhaft geschieht dies dadurch, daß die aus einem elastomeren Kunststoff (z. B. hochelastischem Sili­kongummi einer Härte von maximal 50 Shore A, welches zur Verbesserung der Gleitfähigkeit eine Oberflächenbehandlung durch Talkumieren, Glimmern o. ä. erfahren hat) bestehenden lippenförmigen Schabe- oder Gleit-Leisten Rastmittel 9 zum Hintergreifen von damit korrespondierenden Hinterschneidun­gen 10 in den Stirnseiten der freien U-Schenkel der Füh­rungsschiene 2 aufweisen. Die Rastmittel 9 können grundsätz­lich punktuell, d. h. mit Abstand voneinander, vorgesehen sein, vorzugsweise erstrecken sie sich aber zumindest über längere Teilstücke und am besten über die Gesamtlänge der Dichtungsanordnung ohne Unterbrechung. In dem Ausführungsbei­spiel ist in der unteren Stirnseite der Schenkel der Füh­rungsschiene 2 eine nach unten offene Nut 24 mit einsprin­genden Randstegen 13, 14 vorgesehen und sind die Rastmittel durch einen im Querschnitt pfeilspitzen- oder pilzförmigen Profilsteg 21 an den Schabe- oder Gleit-Leisten 6A, 6B ge­ bildet, der mit den vorspringenden Teilen die Randstege 13, 14 hintergreift. Ein flacher Lippenteil 16 liegt von außen an der unteren Stirnseite zu beiden Seiten der Öffnung der Nut 24 an und kragt von dort im kräftefreien Zustand, wie er in der obersten Stellung nach Fig. 1 im wesentlichen ge­geben ist, horizontal nach innen bis an die Dichtungs­leiste 5 vor. In dieser Position stützt sich der Lippenteil 16 in seinem inneren Bereich am Randsteg 14 ab. Wird der Dich­tungsträger 1 abgesenkt, so biegt sich der flache Lippenteil 16 in der aus Fig. 2 ersichtlichen Weise nach unten, wobei die dichtende Anlage an der Dichtungsleiste 5 erhalten bleibt.At the free U-leg ends of the guide rail 2, a scraping or sliding bar 6A or 6B is attached. This is advantageously done in that the lip-shaped scraping or sliding made of an elastomeric plastic (e.g. highly elastic silicone rubber with a hardness of at most 50 Shore A, which has been given a surface treatment by talc, mica or the like to improve the lubricity) -Last detent means 9 for engaging behind corresponding undercuts 10 in the end faces of the free U-legs of the guide rail 2. The latching means 9 can in principle be provided punctually, ie at a distance from one another, but they preferably extend at least over longer sections and preferably over the entire length of the sealing arrangement without interruption. In the exemplary embodiment, a downwardly open groove 24 with projecting edge webs 13, 14 is provided in the lower end face of the leg of the guide rail 2 and the latching means are provided on the scraping or sliding strips 6A by a cross-section arrowhead or mushroom-shaped profile web 21, 6B ge forms, which engages behind the edge webs 13, 14 with the projecting parts. A flat lip part 16 lies from the outside on the lower end face on both sides of the opening of the groove 24 and projects from there in the force-free state, as is essentially the case in the uppermost position according to FIG. 1, horizontally inwards to the sealing strip 5 before. In this position, the lip part 16 is supported in its inner region on the edge web 14. If the seal carrier 1 is lowered, the flat lip part 16 bends downward in the manner shown in FIG. 2, the sealing contact on the sealing strip 5 being retained.

Die Dichtungsleiste 5 besteht aus einem Schlauch aus einem elastomeren Material, welches formsteifer als dasjeni­ge der Schabe- oder Gleit-Leisten 6A, 6B ist, d. h. einem Hohlkammerprofil, welches mit der flachen Oberseite 5" an der Unterseite des Steges des im Querschnitt U-förmigen Dichtungsträgers 3 anliegt und dort mit Rastmitteln 19 Hin­terschneidungen des Dichtungsträgers 3 hintergreift. Der Außenumfang der Dichtungsleiste 5 hat im Querschnitt etwa die Gestalt einer liegenden halben Ellipse, die nach unten konvex ist, so daß gegen die Schabe- oder Gleit-Leisten 6A, 6B hin zu beiden Seiten eines mittleren Teils 5′ des Außen­umfangs Flächenbereiche 22 vorhanden sind, die schräg nach unten und innen geneigt sind und an denen die Schabe- oder Gleit-Leisten 6A, 6B mit dem vorderen Rand 18 des flachen Lippenteils 16 anliegen und bei Höhenverlagerungen des Dich­tungskörpers 1 abgleiten. Wie aus Fig. 1 ersichtlich ist, bilden die Schabe- oder Gleit-Leisten 6A, 6B bei angehobenem Dichtungskörper 1 mit dem mittleren Teil 5′ der Dichtleiste 5 eine im wesentlichen in gleicher Höhe durchgehende geschlos­sene Begrenzungsfläche der Dichtungsanordnung 100 nach un­ten. Bei abgesenktem Dichtungskörper 1 liegt die Dicht-­Leiste 5 mit dem mittleren Teil 5′ auf dem Boden B auf und gleicht durch ihre elastische Nachgiebigkeit kleinere Un­ ebenheiten des Bodens aus, so daß es zu einer über die Brei­te der Tür T gleichmäßigen Abdichtung kommt.The sealing strip 5 consists of a hose made of an elastomeric material which is more dimensionally stable than that of the scraping or sliding strips 6A, 6B, ie a hollow chamber profile which has a flat top 5 "on the underside of the web of U-shaped cross section Seal carrier 3 rests and there engages undercuts of the seal carrier 3 with latching means 19. The outer circumference of the sealing strip 5 has approximately the shape of a lying half ellipse in cross section, which is convex downward, so that against the scraping or sliding strips 6A, 6B on both sides of a central part 5 'of the outer circumference surface areas 22 are present, which are inclined downwards and inwards and against which the scraping or sliding strips 6A, 6B abut with the front edge 18 of the flat lip part 16 and when the height changes Slide off the sealing body 1. As can be seen from Fig. 1, the scraping or sliding strips 6A, 6B form when the thickness is raised Htungsungskörper 1 with the central part 5 'of the sealing strip 5 a substantially continuous at the same height closed boundary surface of the seal assembly 100 down. When the sealing body 1 is lowered, the sealing strip 5 rests with the central part 5 'on the bottom B and, due to its elastic flexibility, is smaller Un flatness of the floor, so that there is a uniform sealing across the width of the door T.

Zwischen den Schenkeln der im Querschnitt U-förmigen Führungsschiene 2 sind um einen der Breite der Nuten 24 ent­sprechenden Betrag nach innen versetzte Führungsstege 11 vorgesehen, die einander parallele ebene vertilale Führungs­flächen 25 bilden, zwischen denen der Dichtungsträger 3 mit seinen einander parallelen ebenen Außenflächen 26 glei­tend geführt ist.Between the legs of the cross-sectionally U-shaped guide rail 2 are provided by an amount corresponding to the width of the grooves 24 inwardly spaced guide webs 11, which form parallel planar vertical guide surfaces 25, between which the seal carrier 3 with its mutually parallel flat outer surfaces 26 slidably is led.

Schutzleisten an den Außenseiten der freien U-Schenkel­enden der Führungsschiene 2 schützen sowohl die Dichtungs­leiste 5 als auch und insbesondere die Schabe- oder Gleit-­Leisten 6A und 6B. Im übrigen bilden die zum Boden B pa­rallelen Außenflächen der Profilstege 13, 14 Anlageflächen für einen äußeren, in der Ebene des flachen Lippenteils 16 gelegenen Vorsprung 15 bzw. die Oberseite des flachen Lip­penteils 16 in dessen Wurzelbereich.Protective strips on the outer sides of the free U-leg ends of the guide rail 2 protect both the sealing strip 5 and, in particular, the scraping or sliding strips 6A and 6B. Otherwise, the outer surfaces of the profile webs 13, 14 parallel to the bottom B form contact surfaces for an outer projection 15 located in the plane of the flat lip part 16 or the upper side of the flat lip part 16 in the root region thereof.

Mit den flachen Lippenteilen 16 überdecken die Schabe­oder Gleit-Leisten 6A, 6B die zwischen der Führungsschiene 2 einerseits und dem Dichtungskörper 3 andererseits notwendi­gerweise vorhandenen Luftspalte 17 gegen den Eintritt von Verschmutzungen, Nässe u. dgl.. Bei einem äußeren Druck ver­stärken sich Anlage und Dichtwirkung.With the flat lip parts 16, the scraping or sliding strips 6A, 6B cover the air gaps 17 which are necessarily present between the guide rail 2 on the one hand and the sealing body 3 on the other hand against the ingress of dirt, moisture and the like. The like. At an external pressure, the system and sealing effect increase.

Bei der Ausführungsform nach Fig. 3 ist der Lippen­teil 16 auch in der (dargestellten) obersten Arbeitsposi­tion des Dichtungskörpers 1 schräg nach unten geneigt. Für die Befestigung der Schabe- oder Gleitleisten 6A und 6B kön­nen deren Befestigungsteile 21 sehr einfach, nämlich als ebene Stege ausgestaltet sein. Die an der Führungsschiene 2 vorgesehene Nuten 24 weisen ebenfalls Hinterschneidungen 10 auf, die im Zusammenwirken mit entsprechend geformten Pro­filstegen 13 und 14 an die Querschnittsform des Befesti­gungsteiles 21 und der Abwinklung zum Lippenteil 16 hin formangepaßt sind.In the embodiment according to FIG. 3, the lip part 16 is also inclined downwards in the uppermost working position (shown) of the sealing body 1. For the fastening of the scraping or sliding strips 6A and 6B, their fastening parts 21 can be designed very simply, namely as flat webs. The grooves 24 provided on the guide rail 2 also have undercuts 10 which, in cooperation with correspondingly shaped profile webs 13 and 14, are adapted to the shape of the cross section of the fastening part 21 and the angled portion towards the lip part 16.

Bei dem Ausführungsbeispiel gemäß Fig. 4 sind langge­streckte Bürsten 27 anstelle der Lippenteile 16 in den übri­gen Ausführungsbeispielen vorgesehen. Die Bürstenhaare 28 liegen mit ihren Spitzen bzw. mit ihren freien Endbereichen in praktisch allen Arbeitspositionen des Dichtungskörpers 1 an diesem, vorzugsweise an den seitlichen, insbesondere ver­tikalen Flanken des Dichtungsträgers 3 an. Sie bieten auf­grund ihrer Vielzahl eine ausreichende "Dichtigkeit" im Sinne des hier zu erfüllenden Zwecks. Die übrigen Einzelhei­ten entsprechen wiederum sinngemäß denen in den übrigen Ausführungsbeispielen und sind deshalb identisch beziffert.In the exemplary embodiment according to FIG. 4, elongated brushes 27 are provided instead of the lip parts 16 in the remaining exemplary embodiments. The brush hairs 28 rest with their tips or with their free end regions in practically all working positions of the sealing body 1, preferably on the lateral, in particular vertical, flanks of the sealing carrier 3. Because of their large number, they offer sufficient "tightness" in the sense of the purpose to be achieved here. The other details correspond in turn to those in the other exemplary embodiments and are therefore numbered identically.

Im übrigen stützt sich der Befestigungsteil 21 jeder Bürste 27 in der Nut 24 der Führungsschiene 2 an einer lang­gestreckten oder mehreren, etwa mittig vorgesehenen Erhe­bungen 29, insbesondere elastisch, ab.In addition, the fastening part 21 of each brush 27 is supported in the groove 24 of the guide rail 2 on an elongated or several, approximately centrally provided elevations 29, in particular elastic.

Schließlich ist bei dem Ausführungsbeispiel nach Fig. 5 der Lippenteil 16 im wesentlichen entgegengesetzt zu den Lippenteilen nach den Ausführungsbeispielen gemäß Fig. 1 bis 4 geneigt. Diese Ausführungsform hat den Vorteil, daß der Lippenteil 16 lediglich mit der, in der Regel metal­lischen, Führungsschiene 3 in Berührung kommt, und zwar auch dann, wenn sich der Dichtungskörper 1 in seiner obersten Arbeitsposition befindet. Der Lippenteil 16 berührt also nur ein einziges und nicht zwei verschiedene Materialien und kann deshalb hinsichtlich seiner Dicht- und Gleitwirkung besonders vorteilhaft auf das Material und die Oberflächen­form sowie Oberflächenbeschaffenheit des Dichtungsträgers 3 abgestimmt werden. Wie die strichpunktiert dargestellte un­terste Arbeitsposition des Dichtungskörpers 1 zeigt, bleibt auch bei dieser Ausführungsform die Dichtungfunktion des Lippenteiles 16 selbst in dieser Extremposition des Dich­tungskörpers erhalten. Die übrigen Bauteile entsprechen wieder dem in den vorangehenden Ausführungsbeispielen ge­zeigten und sind daher identisch beziffert.Finally, in the exemplary embodiment according to FIG. 5, the lip part 16 is inclined essentially in the opposite direction to the lip parts according to the exemplary embodiments according to FIGS. 1 to 4. This embodiment has the advantage that the lip part 16 only comes into contact with the, usually metallic, guide rail 3, even when the sealing body 1 is in its uppermost working position. The lip part 16 therefore only touches a single and not two different materials and can therefore be particularly advantageous with regard to its sealing and sliding action on the material and the surface shape and surface quality of the seal carrier 3 be coordinated. As the lower working position of the sealing body 1 shown in dash-dotted lines shows, the sealing function of the lip part 16 is retained even in this extreme position of the sealing body in this embodiment. The remaining components correspond to those shown in the previous exemplary embodiments and are therefore numbered identically.
