Definitions

  • a vertical offset of adjacent sealing strips can lead to areas in which the sealing profiles do not lie tightly on the floor, for example.
  • the seal shown has a very simple mechanism with which the sealing strips can be moved relative to the holding means.
  • the sealing strips that are connected to one another are greatly offset in relation to the holding means when they are lowered. So that this does not result in a gap that is not sealed at the end of the seal into which the sealing strip is not placed, the seal or the segments of the seal are designed in such a way that the sealing strip fills the gap between the Door leaf to which the seal is attached and can seal the floor at any point.
  • the sealing strip protrudes laterally very far beyond the holding means and also the door leaf. This can lead to problems with a swing door if the sealing strip hits a door frame of the door when it is closed.
  • the overhang of the sealing strip should therefore not be too large.
  • at least the retaining bar even jumps back behind the door leaf, so that any risk of the door frame hitting or grazing with the retaining bar is avoided.
  • the holding strip would then be shorter than the segment of the seal all in all. Since the segments of the seal are preferably of the same design in order to use as many identical parts as possible, this means that it is not possible for the retaining strips of adjacent segments to directly abut one another if the retaining strips are set back.
  • this can lead to limitations in the connection of the retaining strips of adjacent segments and/or in the transmission of force, for example the force required for lowering between the retaining strips of adjacent segments.
  • the present invention is based on the problem that, despite the retaining strip springing back behind the ends of the length of the sealing segments determined by the retaining means, a firm and resilient connection between the retaining strips of adjacent segments is possible.
  • each connector has a collar arranged between the plug-in sections in the main direction of extent of the sealing strip, the collar at least partially protruding beyond the plug-in sections in a plane perpendicular to the direction of main extent of the sealing strip.
  • the collar provided according to the invention makes it possible for the retaining strips of adjacent segments to be connected to one another in such a way that forces can be easily transferred from one retaining strip.
  • the distance between the retaining strips of two adjacent segments of the seal is preferably at least partially or completely filled by the collar of the connector inserted into these retaining strips.
  • the retaining strip of each segment in the main direction of extension of the sealing strip, can be set back relative to the sealing profile of the segment. Conversely, this means that the sealing profile can protrude beyond the retaining strip. This is particularly useful for a gapless seal at the ends of the seals located in the main direction of extension of the sealing strips, but also at the individual seal segments.
  • the collar is preferably designed in such a way that a joint between the two sealing profiles fastened to the retaining strips is backed by the collar of the connector inserted into these retaining strips.
  • the sealing profiles of the two adjacent segments can rest against the collar, in particular when the seal is in a lowered state.
  • the sealing profiles can be sealed off from the collar, even if the sealing profiles do not abut one another without a gap. It is even possible that the sealing profiles are connected to the collar in the area of the joint.
  • the sealing profiles can be glued to the collar.
  • Each retaining strip of a segment of a seal according to the invention has at least one channel into which a retaining web of the sealing profile is inserted.
  • each connector can have at least one recess which continues the channels of the adjacent retaining strips and connects them to one another.
  • sections of the Retaining webs of the sealing profiles can be fastened in the at least one recess of the connector.
  • the plug-in sections of at least one of the connectors but if possible all of the connectors of a seal according to the invention, can taper from the collar to their free ends. The tapered ends make it easier to insert the plug-in sections into the holding strips.

  • the mechanism can be implemented in a manner known in the prior art.
  • the movement of the sealing strips 22, 23 of the segments 1, 2 out of the housing can be triggered by a force on a trigger of the first segment 1.
  • the mechanisms 24 of the segments are coupled to one another. If the trigger is released, the sealing strip 22, 23 is moved into the housing 21 by the mechanisms 24.
  • the European patent application 18 186 115.4 is shown as an example of how the mechanisms 24 of the segments 1, 2 can be constructed, how they work and how they are coupled to one another.

Description

Die vorliegende Erfindung betrifft eine Dichtung mit mehreren Segmenten, wobei jedes Segment

  • wenigstens ein Haltemittel,
  • eine Dichtleiste umfassend eine Halteleiste und ein Dichtungsprofil und
  • einen Mechanismus
    aufweist,
  • wobei der Mechanismus jedes der Segmente das wenigstens eine Haltemittel und die Dichtleiste des gleichen Segmentes miteinander verbindet, die Dichtleiste mittels des Mechanismus gegenüber dem wenigstens einen Haltemittel quer zu ihrer Haupterstreckung verschiebbar ist,
  • wobei die Dichtung Verbinder aufweist, die die Halteleisten der Dichtleisten benachbarter Segmente miteinander verbinden, wozu die Verbinder in Enden der Halteleisten der Dichtleisten benachbarter Segmente eingesteckt sind, und
  • wobei jeder Verbinder zwei Einsteckabschnitte aufweist, die in je ein Ende der Halteleisten eingesteckt sind.
The present invention relates to a multi-segment seal, each segment
  • at least one holding device,
  • a sealing strip comprising a retaining strip and a sealing profile and
  • a mechanism
    having,
  • wherein the mechanism of each of the segments connects the at least one holding means and the sealing strip of the same segment to one another, the sealing strip can be displaced transversely to its main extent relative to the at least one holding means by means of the mechanism,
  • wherein the seal has connectors which connect the retaining strips of the sealing strips of adjacent segments to one another, for which purpose the connectors are inserted into ends of the retaining strips of the sealing strips of adjacent segments, and
  • each connector having two male portions which are inserted into respective ends of the retaining strips.

Aus dem Dokument US 5 454 192 A ist eine Dichtung mit den vorgenannten Merkmalen bekannt. Durch den Aufbau der Dichtung aus mehreren Segmenten ist es möglich, die Dichtung zu verlängern, um damit zum Beispiel den Spalt zwischen einem Tor und dem Boden abzudichten. Die Dichtleisten der Segmente dieser Dichtung sind durch die Verbinder miteinander verbunden. Die Einsteckabschnitte sind in die Enden der Halteleisten eingesteckt. Die Halteleisten stoßen stirnseitig mit ihren Enden aneinander, so dass auch eine Druckkraft von einem Halteprofil zum nächsten Halteprofil übertragen werden kann.From the document U.S. 5,454,192 A a seal with the aforementioned features is known. Because the seal is made up of several segments, it is possible to lengthen the seal, for example to seal the gap between a goal and the floor. The sealing strips of the segments of this seal are connected to one another by the connectors. The plug-in sections are plugged into the ends of the holding strips. The ends of the retaining strips butt against one another at the front, so that a compressive force can also be transmitted from one retaining profile to the next retaining profile.

Das ist bei der in dem Dokument US 5 454 192 A dargestellten Dichtung zum Einen notwendig, um das Absenken aller Dichtleisten zuverlässig zu ermöglichen. Es ist zum Anderen auch sinnvoll, um einen Versatz zwischen benachbarten Dichtleisten zu vermeiden. Durch einen vertikalen Versatz benachbarter Dichtleisten kann es zu Bereichen kommen, in denen die Dichtungsprofile zum Beispiel nicht dichtend auf dem Boden aufliegen. Es kann auch zu Lücken zwischen den Dichtungsprofilen benachbarter Dichtleisten kommen, zum Beispiel wenn die Dichtleisten quer zu ihrer Haupterstreckungsrichtung versetzt zueinander sind oder die Dichtungsprofile nach einer Betätigung in der Haupterstreckungsrichtung der Dichtleiste nicht aneinanderstoßen und somit nicht dichtend aneinander liegen.That's with the one in the document U.S. 5,454,192 A shown seal necessary to lower all sealing strips to enable reliably. On the other hand, it is also useful to avoid an offset between adjacent sealing strips. A vertical offset of adjacent sealing strips can lead to areas in which the sealing profiles do not lie tightly on the floor, for example. There may also be gaps between the sealing profiles of adjacent sealing strips, for example if the sealing strips are offset from one another transversely to their main direction of extent or the sealing profiles do not abut one another after actuation in the main direction of extent of the sealing strip and therefore do not lie tightly against one another.

Die in dem Dokument US 5 454 192 A dargestellte Dichtung weist einen sehr einfachen Mechanismus auf, mit dem die Dichtleisten gegenüber dem Haltemittel bewegt werden kann. Die miteinander verbundenen Dichtleisten werden beim Absenken gegenüber dem Haltemittel stark versetzt. Damit sich dadurch nicht an dem Ende der Dichtung, in die die Dichtleiste nicht versetzt wird, eine Lücke ergibt, die nicht abgedichtet ist, ist die Dichtung bzw. sind die Segmente der Dichtung so konstruiert, dass die Dichtleiste im abgesenkten Zustand den Spalt zwischen dem Türblatt, an dem die Dichtung befestigt ist, und dem Fußboden an jeder Stelle abdichten kann. Im nicht abgesenkten Zustand überragt die Dichtleiste dagegen die Haltemittel und auch das Türblatt seitlich sehr weit. Das kann zu Problemen bei einer Drehflügeltür führen, wenn die Dichtleiste beim Schließen vor einen Türrahmen der Tür schlägt.The ones in the document U.S. 5,454,192 A The seal shown has a very simple mechanism with which the sealing strips can be moved relative to the holding means. The sealing strips that are connected to one another are greatly offset in relation to the holding means when they are lowered. So that this does not result in a gap that is not sealed at the end of the seal into which the sealing strip is not placed, the seal or the segments of the seal are designed in such a way that the sealing strip fills the gap between the Door leaf to which the seal is attached and can seal the floor at any point. In the non-lowered state, on the other hand, the sealing strip protrudes laterally very far beyond the holding means and also the door leaf. This can lead to problems with a swing door if the sealing strip hits a door frame of the door when it is closed.

Daher sollte der Überstand der Dichtleiste nicht zu groß sein. Vorzugweise springt zumindest die Halteleiste sogar hinter dem Türblatt zurück, so dass jegliche Gefahr eines Anschlagens oder Streifens des Türrahmens mit der Halteleiste vermieden wird. Die Halteleiste wäre dann kürzer als das Segment der Dichtung insgesamt. Da die Segmente der Dichtung vorzugsweise gleich ausgebildet sind, um möglichst viele Gleichteile zu verwenden, führt das dazu, dass ein unmittelbares Aneinanderstoßen der Halteleisten benachbarter Segmente bei einem Rücksprung der Halteleisten nicht möglich ist.The overhang of the sealing strip should therefore not be too large. Preferably, at least the retaining bar even jumps back behind the door leaf, so that any risk of the door frame hitting or grazing with the retaining bar is avoided. The holding strip would then be shorter than the segment of the seal all in all. Since the segments of the seal are preferably of the same design in order to use as many identical parts as possible, this means that it is not possible for the retaining strips of adjacent segments to directly abut one another if the retaining strips are set back.

Das kann letztlich zu Einschränkungen bei der Verbindung der Halteleisten von benachbarten Segmenten und/oder bei der Kraftübertragung zum Beispiel der für die Absenkung notwendigen Kraft zwischen den Halteleisten von benachbarten Segmenten führen.Ultimately, this can lead to limitations in the connection of the retaining strips of adjacent segments and/or in the transmission of force, for example the force required for lowering between the retaining strips of adjacent segments.

Hier setzt die vorliegende Erfindung an.This is where the present invention comes in.

Der vorliegenden Erfindung liegt das Problem zugrunde, dass trotz eines Rückspringens der Halteleiste hinter die Enden der durch die Haltemittel bestimmten Länge der Dichtungssegmente eine feste und belastbare Verbindung zwischen den Halteleisten benachbarter Segmente möglich ist.The present invention is based on the problem that, despite the retaining strip springing back behind the ends of the length of the sealing segments determined by the retaining means, a firm and resilient connection between the retaining strips of adjacent segments is possible.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass jeder Verbinder einen in der Haupterstreckungsrichtung der Dichtleiste zwischen den Einsteckabschnitten angeordneten Kragen aufweist, wobei der Kragen die Einsteckabschnitte in einer Ebene senkrecht zur Haupterstreckungsrichtung der Dichtleiste zumindest teilweise überragt.This problem is solved according to the invention in that each connector has a collar arranged between the plug-in sections in the main direction of extent of the sealing strip, the collar at least partially protruding beyond the plug-in sections in a plane perpendicular to the direction of main extent of the sealing strip.

Der erfindungsgemäß vorgesehen Kragen macht es möglich, dass die Halteleisten benachbarter Segmente so miteinander verbunden werden können, dass Kräfte gut von einer Halteleiste übertragen werden können.The collar provided according to the invention makes it possible for the retaining strips of adjacent segments to be connected to one another in such a way that forces can be easily transferred from one retaining strip.

Vorzugsweise ist der Abstand zwischen den Halteleisten zweier benachbarter Segmente der Dichtung von dem Kragen des in diese Halteleisten eingesteckten Verbinders zumindest teilweise oder vollständig ausgefüllt.The distance between the retaining strips of two adjacent segments of the seal is preferably at least partially or completely filled by the collar of the connector inserted into these retaining strips.

Gemäß der Erfindung kann in der Haupterstreckungsrichtung der Dichtleiste die Halteleiste jedes Segmentes gegenüber dem Dichtungsprofil des Segmentes zurückspringen. Umgekehrt ausgedrückt bedeutet dies, dass das Dichtungsprofil die Halteleiste überragen kann. Das ist insbesondere für eine lückenlose Abdichtung an den in der Haupterstreckungsrichtung der Dichtleisten liegenden Enden der Dichtungen, aber auch der einzelnen Dichtungssegmente sinnvoll.According to the invention, in the main direction of extension of the sealing strip, the retaining strip of each segment can be set back relative to the sealing profile of the segment. Conversely, this means that the sealing profile can protrude beyond the retaining strip. This is particularly useful for a gapless seal at the ends of the seals located in the main direction of extension of the sealing strips, but also at the individual seal segments.

Vorzugsweise ist der Kragen so gestaltet, dass ein Stoß zwischen den zwei an den Halteleisten befestigten Dichtungsprofilen durch den Kragen des in diese Halteleisten eingesteckten Verbinders hinterlegt ist. Die Dichtungsprofile der beiden benachbarten Segmente können sich insbesondere in einem abgesenkten Zustand der Dichtung an den Kragen anlegen. Es kann dadurch eine Abdichtung der Dichtungsprofile zu dem Kragen erfolgen, selbst wenn die Dichtungsprofile nicht lückenlos aneinanderstoßen. Es ist sogar möglich, dass die Dichtungsprofile im Bereich des Stoßes mit dem Kragen verbunden sind. So können die Dichtungsprofile zum Beispiel an dem Kragen angeklebt sein.The collar is preferably designed in such a way that a joint between the two sealing profiles fastened to the retaining strips is backed by the collar of the connector inserted into these retaining strips. The sealing profiles of the two adjacent segments can rest against the collar, in particular when the seal is in a lowered state. As a result, the sealing profiles can be sealed off from the collar, even if the sealing profiles do not abut one another without a gap. It is even possible that the sealing profiles are connected to the collar in the area of the joint. For example, the sealing profiles can be glued to the collar.

Jede Halteleiste eines Segmentes einer erfindungsgemäßen Dichtung weist wenigstens einen Kanal auf, in welchen ein Haltesteg des Dichtungsprofils eingefügt ist. Dabei kann jeder Verbinder wenigstens eine Ausnehmung aufweisen, die die Kanäle der benachbarten Halteleisten fortsetzt und miteinander verbindet. Abschnitte der Haltestege der Dichtungsprofile können in den wenigstens einen Ausnehmungen der Verbinder befestigt sein. Die Einsteckabschnitte wenigstens eines der Verbinder, möglichst jedoch aller Verbinder einer erfindungsgemäßen Dichtung können von dem Kragen ausgehend sich zu ihren freien Enden verjüngen. Durch die verjüngten Enden ist es erleichtert, die Einsteckabschnitte in die Halteleisten einzuführen. Vorzugsweise wird es dadurch auch erleichtert, die Einsteckabschnitt in dem Verbinder formschlüssig und auch kraftschlüssig zu befestigen.Each retaining strip of a segment of a seal according to the invention has at least one channel into which a retaining web of the sealing profile is inserted. In this case, each connector can have at least one recess which continues the channels of the adjacent retaining strips and connects them to one another. sections of the Retaining webs of the sealing profiles can be fastened in the at least one recess of the connector. The plug-in sections of at least one of the connectors, but if possible all of the connectors of a seal according to the invention, can taper from the collar to their free ends. The tapered ends make it easier to insert the plug-in sections into the holding strips. This preferably also makes it easier to fasten the plug-in section in the connector in a positive and also non-positive manner.

Die in der Fig. 1 dargestellte Dichtung 1 ist aus zwei gleiche Dichtungssegmenten 1, 2 zusammengesetzt. Das Dichtungssegment 2 ist in den übrigen Figuren näher dargestellt. Das Dichtungssegment 2 weist ein als Haltemittel 21 vorgesehenes Gehäuse auf, mit dem die Dichtung D in oder an einem Tor befestigt werden kann. In dem Gehäuse ist ein Mechanismus 24 vorgesehen. Dieser Mechanismus 24 verbindet eine Dichtleiste 22, 23 mit dem Gehäuse 21 in der Art, dass die Dichtleiste 22, 23 gegenüber dem Gehäuse 21 quer zur ihrer Haupterstreckungsrichtung verschoben werden kann. Der Mechanismus kann auf eine aus dem Stand der Technik bekannte Art ausgeführt sein.The one in the 1 seal 1 shown is composed of two identical seal segments 1, 2. The sealing segment 2 is shown in more detail in the other figures. The sealing segment 2 has a housing provided as a holding means 21 with which the seal D can be fastened in or on a gate. A mechanism 24 is provided in the housing. This mechanism 24 connects a sealing strip 22, 23 to the housing 21 in such a way that the sealing strip 22, 23 can be displaced relative to the housing 21 transversely to its main direction of extension. The mechanism can be implemented in a manner known in the prior art.

Über eine Kraft auf einen Auslöser des ersten Segmentes 1 kann die Bewegung der Dichtleisten 22, 23 der Segmente 1, 2 aus dem Gehäuse ausgelöst werden. Die Mechanismen 24 der Segmente sind dazu miteinander gekoppelt. Wird der Auslöser entlastet, wird die Dichtleiste 22, 23 durch die Mechanismen 24 in das Gehäuse 21 hineinbewegt. In der europäischen Patentanmeldung 18 186 115.4 ist beispielhaft dargestellt, wie die Mechanismen 24 der Segmente 1, 2 aufgebaut sein können, wie sie funktionieren und wie sie miteinander gekoppelt sind.The movement of the sealing strips 22, 23 of the segments 1, 2 out of the housing can be triggered by a force on a trigger of the first segment 1. For this purpose, the mechanisms 24 of the segments are coupled to one another. If the trigger is released, the sealing strip 22, 23 is moved into the housing 21 by the mechanisms 24. In the European patent application 18 186 115.4 is shown as an example of how the mechanisms 24 of the segments 1, 2 can be constructed, how they work and how they are coupled to one another.

Die Dichtleisten 22, 23 weisen eine Halteleiste 23 und ein Dichtungsprofil 24 auf.The sealing strips 22, 23 have a holding strip 23 and a sealing profile 24.

Die Halteleiste 23 der Dichtleiste 22, 23 jedes Segmentes kann ein Strangpressprofil, insbesondere ein Aluminiumstrangpressprofil sein. Die Halteleiste ist im Wesentlichen U-förmig und hat einen Steg 232 mit sich an den Enden des Steges 232 anschließenden Schenkeln. Die Halteleiste 23 weist im Bereich der Verbindung zwischen den Schenkeln 234 und dem Steg 232 einen Kanal 231 auf, in den Haltestege 221 der Dichtungsprofile 22 eingesteckt sind. Ferner ist durch nach innen ragende Stege 235 ein weiterer Kanal 236 ausgebildet, in dem Teile des Mechanismus 24 des Segmentes 1, 2 angeordnet sind.The retaining strip 23 of the sealing strip 22, 23 of each segment can be an extruded profile, in particular an aluminum extruded profile. The retaining bar is essentially U-shaped and has a web 232 with the ends of the web 232 adjoining legs. In the region of the connection between the legs 234 and the web 232, the holding strip 23 has a channel 231 into which the holding webs 221 of the sealing profiles 22 are inserted. Furthermore, another channel 236 is formed by inwardly projecting webs 235, in which parts of the mechanism 24 of the segment 1, 2 are arranged.

Die Dichtungsprofile 22 der Dichtleiste 22, 23 der Segmente sind aus einem elastischen Material hergestellt, im Wesentlichen U-förmig und weisen einen Steg 222 und sich an den Enden des Steges 222 anschließende Schenkel 221 auf. Die Dichtungsprofile 22 sind in der Haupterstreckungsrichtung etwas länger als die Halteleisten 23. Die Dichtungsprofile 22 und die Halteleisten 23 sind so zueinander angeordnet, dass die Dichtungsprofile 22 die Enden der Halteleisten 23, an denen sie befestigt sind, überlappen.The sealing profiles 22 of the sealing strip 22, 23 of the segments are made of an elastic material, are essentially U-shaped and have a web 222 and legs 221 adjoining the ends of the web 222. The sealing profiles 22 are slightly longer than the retaining strips 23 in the main extension direction. The sealing profiles 22 and the retaining strips 23 are arranged relative to one another such that the sealing profiles 22 overlap the ends of the retaining strips 23 to which they are attached.

Damit die benachbarten Enden der Dichtleisten 22, 23 benachbarter Segmente 1, 2 ohne Versatz zueinander bewegt werden können, ist vorgesehen, dass die Dichtleisten 22, 23 mittels eines Verbinders 3 miteinander verbunden sind. Die Verbinder 3 weisen zwei Einsteckabschnitte 32 auf, die in die Halteleisten 23 eingesteckt sind. Das Außenprofil der Einsteckabschnitte ist komplementär zur dem lichten Innenprofil der Halteleisten 23. Die Einsteckabschnitte 32 sind in die Kanäle 236 und den darüber befindlichen Räumen zwischen den Schenkeln 221 der Halteleisten 22 eingesteckt. Zwischen den Einsteckabschnitten 32 weist der Verbinder 3 einen Kragen auf, der die Einsteckabschnitte 32 quer zur Haupterstreckungsrichtung der Dichtleisten 22, 23 überragt. Vom Kragen 31 ausgehend verjüngen sich die Einsteckabschnitte 32 geringfügig. Das erleichtert zum einen das Einstecken der Einsteckabschnitte 32 in die Halteleisten 22. Zum anderen erleichtert es trotz Toleranzen der Verbinder 3 wie auch der Halteleisten 22 eine form- und kraftschlüssige Verbindung zwischen den Verbindern 3 und den Halteleisten.So that the adjacent ends of the sealing strips 22 , 23 of adjacent segments 1 , 2 can be moved relative to one another without being offset, provision is made for the sealing strips 22 , 23 to be connected to one another by means of a connector 3 . The connectors 3 have two plug-in sections 32 which are plugged into the holding strips 23 . The outer profile of the plug-in sections is complementary to the clear inner profile of the holding strips 23. The plug-in sections 32 are inserted into the channels 236 and the spaces located above them between the legs 221 of the holding strips 22. Between the plug-in sections 32, the connector 3 has a collar which protrudes beyond the plug-in sections 32 transversely to the main direction of extension of the sealing strips 22, 23. Starting from the collar 31, the plug-in sections 32 taper slightly. On the one hand, this makes it easier to insert the plug-in sections 32 into the holding strips 22. On the other hand, it makes it easier, despite the tolerances of the connector 3 and the Retaining strips 22 a positive and non-positive connection between the connectors 3 and the retaining strips.

Der Kragen 31 hat zum Teil, insbesondere an seinen Seitenflächen 312, das gleiche Außenprofil wie die Halteleisten 23. Insbesondere weist der Kragen in den Seitenflächen 312 je eine Ausnehmung 311 auf, die eine Fortsetzung der Kanäle 231 bildet, in die die Haltestege 221 der Bereiche der Dichtungsprofile 22 eingesteckt sind, die die Halteleisten 23 überragen. Die Enden der Dichtungsprofile 22 sind dadurch an den Verbindern 3 befestigt.The collar 31 has in part, in particular on its side surfaces 312, the same external profile as the retaining strips 23. In particular, the collar has a recess 311 in each of the side surfaces 312, which forms a continuation of the channels 231, into which the retaining webs 221 of the areas of the sealing profiles 22 are inserted, which protrude beyond the retaining strips 23. The ends of the sealing profiles 22 are fastened to the connectors 3 as a result.

Auf seiner Unterseite 313 überragt der Kragen 31 dagegen die Halteleisten 23. Diese Unterseite 313 wird bei einer Bewegung der Dichtleisten 22, 23 einschließlich der Dichtungsprofile 22 gegen eine Gegenfläche von innen gegen die Stelle gedrückt, an der die Dichtungsprofile der über den Verbinder 31 verbunden Dichtleisten 22, 23 aneinanderstoßen. Die Unterseite 313 drückt damit zum einen von innen auf die Dichtungsprofile und dichtet gegenüber den Dichtungsprofilen, zum anderen drückt die Unterseite 313 die Dichtungsprofile 22 gegen die Gegenfläche, so dass die Dichtungsprofile 22 auch gegenüber der Gegenfläche abdichten. Obwohl zwischen den Dichtungsprofilen 22 der benachbarten Dichtleisten 22, 23 aufgrund von Toleranzen und aus anderen Gründen an der Stoßstelle eine Lücke entstehen kann, kann diese durch die die Halteleisten 23 überragende Unterseite 313 abgedichtet werden, solange die Lücke sich im Bereich des Kragens befindet.On the other hand, on its underside 313, the collar 31 protrudes beyond the retaining strips 23. When the sealing strips 22, 23 including the sealing profiles 22 move against an opposing surface, this underside 313 is pressed from the inside against the point at which the sealing profiles of the sealing strips connected via the connector 31 22, 23 abut. The underside 313 thus presses on the sealing profiles from the inside and seals against the sealing profiles, and on the other hand the underside 313 presses the sealing profiles 22 against the opposing surface, so that the sealing profiles 22 also seal against the opposing surface. Although there may be a gap between the sealing profiles 22 of the adjacent sealing strips 22, 23 due to tolerances and other reasons at the joint, this can be sealed by the underside 313 protruding beyond the retaining strips 23 as long as the gap is in the area of the collar.
