Definitions

  • the document US 5 454 192 A discloses an automatic seal for a door, which has a carrier attachable to the door, a plurality of first connecting elements fastened to the carrier and a sealing strip carried by the first connecting elements, wherein the carrier, the first connecting elements and the retaining strip are formed by one part.
  • a sealing element is fastened to the retaining strip. The retaining strip and the sealing element together form the sealing strip.
  • the plurality of connecting elements couple the retaining strip and the carrier and hold the retaining strip in a release position, wherein the retaining strip in the release position is spaced from a counter surface, for example a floor, a ceiling, a wall, a threshold or a frame part of a door frame or other, so that the door can be moved without the sealing element attached to the retaining strip rubbing against the counter surface.
  • a counter surface for example a floor, a ceiling, a wall, a threshold or a frame part of a door frame or other
  • the connecting elements are flexible and/or the connection between the connecting elements and the carrier and the sealing strip is flexible.
  • the first connecting elements, the carrier and the sealing strip form a parallel link, in which the sealing strip can be moved parallel to the carrier and at the same time in its longitudinal direction. To do this, a force can be exerted on the retaining strip in the longitudinal direction of the retaining strip.
  • a force can be introduced into the retaining strip, which presses the retaining strip into a sealing position in which the retaining strip is pressed against the opposing surface, for example a floor, a ceiling, a wall, a threshold or a frame part of a door frame, in order to seal the door.
  • the first connecting elements form one part with the carrier and with the retaining strip.
  • This part can in particular be a plastic injection-molded part.
  • the one-piece design of the support, the connecting elements and the retaining strip reduces the number of parts required to manufacture the seal. This has advantages for the manufacture of the seal. By using a part that is easy to manufacture and which replaces a large part of the parts required in a conventional automatic seal just to create the mechanism for raising and lowering, it is possible to reduce costs.
  • a known seal comprises, in addition to the part formed by the carrier, the first connecting elements and the retaining strip, further elements, namely at least one sealing profile or element as a further element of the sealing strip and a cover which covers the carrier and the connecting elements and, in the release position, also the sealing strip. At least these two elements must be connected to the part formed by the carrier, the connecting elements and the retaining strip in order to produce a seal.
  • a disclosed seal may be that the force required to actuate the seal is introduced into the seal by the retaining strip striking a door frame.
  • the force introduction or actuation thus initiated moves the retaining strip from its release position into the sealing position, i.e. the retaining strip moves relative to the door frame.
  • the retaining strip or a stop element possibly attached to the retaining strip which strikes the door frame drags over the surface of the door frame due to the relative movement between the door frame and the retaining strip. This dragging can damage the retaining strip or the stop element or the door frame.
  • the pressure of the door frame on the stop element or the retaining strip can be so great that movement of the retaining strip relative to the door frame and also to the support is hindered.
  • a force transmission element is provided which is a component of the second part, but is also arranged to be displaceable in the first part.
  • This force transmission element can now be used to absorb a force in the seal and to transmit it further in the seal so that it can be used in the seal to move the sealing strip from the release position to the sealing position.
  • the force transmission element is not attached to the sealing strip and cannot be moved with the sealing strip from its release position to its sealing position and vice versa.
  • the first connecting element and/or the second connecting element of a seal according to the invention, the connection between the carrier and the first end of the first connecting element, the connection between the second end of the first connecting element and the retaining strip, the connection between the first end of the second connecting element and the carrier and/or the connection between the second end of the second connecting element and the retaining strip can be flexible.
  • the flexibility makes it possible for a force to be stored in the elements or connections mentioned, which force is needed for the return movement of the sealing strip from the sealing position to the release position after the seal has been actuated and the sealing strip has moved from the release position to the sealing position.
  • the first and/or the second part which has the force transmission element, the first connecting element, the second connecting element and the retaining strip as components, can be made of plastic and in particular be a plastic injection-molded part.
  • the force transmission element of a seal according to the invention can have a window through which the first end of the second connecting element extends or in which the first end of the second connecting element is arranged.
  • the end of the second connecting element extending through the window can thus be attached to the first part without affecting the displaceability of the force transmission element.
  • a A hole may be provided in which a button or rivet or the like is arranged, which connects the two elements together.
  • the carrier can have a guide channel extending in its longitudinal direction in which the force transmission element is slidably arranged.
  • the sealing element can be a component of the second part.
  • the second part can consist of several plastic components of different hardness and/or flexibility.
  • a seal according to the invention can have at least two pairs each consisting of a first part and a second part, namely the first pair and a last pair.
  • the first part of the last pair and the second part of the last pair have the same features, in particular as mentioned in claim 1, as the parts of the first pair.
  • the first part and the second part of the last pair can be identical or partially identical to the parts of the first or last pair.
  • a second end of the support of the first pair may be connected to a first end of the support of the last pair, and a second end of the force transmission means of the first pair may be connected to a first end of the force transmission means of the last pair.
  • a second end of the retaining bar of the first pair may be connected to a first end of the retaining bar of the last pair.
  • a seal according to the invention may comprise, in addition to the first and last pairs, further pairs of first and second parts arranged between the first pair and the last pair.
  • the first part of the further pair and the second Parts of the further pair have the same features, in particular as mentioned in claim 1, as the parts of the first pair or the last pair.
  • the first parts and the second parts of the further pairs can be identical or partially identical to the parts of the first or the last pair.
  • a seal according to the invention can have a stop element which is formed by the first end of the force transmission element of the second part of the first pair or is provided as a one- or multi-part component which is connected to the first end of the force transmission element.
  • a seal according to the invention can have fastening elements, for example fastening angles, which are connected to the first end of the support of the first pair on the one hand and either to the second end of the support of the first pair or possibly the last pair on the other hand.
  • the fastening angles can be inserted into the guide channel with one leg and attached to a door leaf with a second leg.

Description

Die vorliegende Erfindung betrifft eine automatische Türdichtung mit einem ersten Paar aus einem ersten einteiligen Teil und einem zweiten einteiligen Teil, nämlich

  1. a. mit einem Träger als Bestandteil des ersten Teils,
  2. b. mit wenigstens einem ersten Verbindungselement und
  3. c. mit einer Dichtungsleiste umfassend eine Halteleiste und ein Dichtungselement,
  4. d. wobei das erste Verbindungselement und die Halteleiste Bestandteile des zweiten Teils sind.
The present invention relates to an automatic door seal comprising a first pair of a first one-piece part and a second one-piece part, namely
  1. a. with a carrier as part of the first part,
  2. b. with at least one first connecting element and
  3. c. with a sealing strip comprising a retaining strip and a sealing element,
  4. d. wherein the first connecting element and the retaining strip are components of the second part.

Das Dokument US 5 454 192 A offenbart eine automatische Dichtung für eine Tür, die einen an der Tür anbringbaren Träger, eine Vielzahl von an dem Träger befestigten ersten Verbindungselementen und eine von den ersten Verbindungselementen getragene Dichtungsleiste aufweist, wobei der Träger, die ersten Verbindungselemente und die Halteleiste durch ein Teil gebildet sind. An der Halteleiste ist ein Dichtungselement befestigt. Die Halteleiste und das Dichtungselement bilden zusammen die Dichtungsleiste.The document US 5 454 192 A discloses an automatic seal for a door, which has a carrier attachable to the door, a plurality of first connecting elements fastened to the carrier and a sealing strip carried by the first connecting elements, wherein the carrier, the first connecting elements and the retaining strip are formed by one part. A sealing element is fastened to the retaining strip. The retaining strip and the sealing element together form the sealing strip.

Die Vielzahl von Verbindungselementen koppeln die Halteleiste und den Träger und halten die Halteleiste in einer Freigabestellung, wobei die Halteleiste in der Freigabestellung einen Abstand zu einer Gegenfläche, zum Beispiel einem Fußboden, einer Decke, einer Wand, einer Schwelle oder einem Rahmenteil eines Türrahmens oder anderem, hat, so dass die Tür bewegt werden kann, ohne dass das an der Halteleiste befestigte Dichtungselement an der Gegenfläche schleift.The plurality of connecting elements couple the retaining strip and the carrier and hold the retaining strip in a release position, wherein the retaining strip in the release position is spaced from a counter surface, for example a floor, a ceiling, a wall, a threshold or a frame part of a door frame or other, so that the door can be moved without the sealing element attached to the retaining strip rubbing against the counter surface.

Die Verbindungselemente sind flexibel und/oder die Verbindung zwischen den Verbindungselementen und dem Träger und der Dichtungsleiste sind flexibel. Die ersten Verbindungselemente, der Träger und die Dichtungsleiste bilden einen Parallellenker, bei dem die Dichtungsleiste parallel zum Träger und gleichzeitig in ihrer Längsrichtung verschoben werden kann. Dazu kann eine Kraft auf die Halteleiste in der Längsrichtung der Halteleiste ausgeübt werden.The connecting elements are flexible and/or the connection between the connecting elements and the carrier and the sealing strip is flexible. The first connecting elements, the carrier and the sealing strip form a parallel link, in which the sealing strip can be moved parallel to the carrier and at the same time in its longitudinal direction. To do this, a force can be exerted on the retaining strip in the longitudinal direction of the retaining strip.

Zur Betätigung der Dichtung kann damit eine Kraft in die Halteleiste eingeleitet werden, die die Halteleiste in eine Dichtstellung drückt, in der die Halteleiste gegen die Gegenfläche, zum Beispiel einen Fußboden, eine Decke, eine Wand, eine Schwelle oder ein Rahmenteil eines Türrahmens, gedrückt wird, um die Tür abzudichten.To actuate the seal, a force can be introduced into the retaining strip, which presses the retaining strip into a sealing position in which the retaining strip is pressed against the opposing surface, for example a floor, a ceiling, a wall, a threshold or a frame part of a door frame, in order to seal the door.

In verschiedenen Ausführungsformen der in dem Dokument US 5 454 192 A offenbarten Dichtung bilden die ersten Verbindungselemente mit dem Träger und mit der Halteleiste ein Teil. Bei diesem Teil kann es sich insbesondere um ein Kunststoffspritzgussteil handeln.In various embodiments of the invention described in the document US 5 454 192 A In the seal disclosed, the first connecting elements form one part with the carrier and with the retaining strip. This part can in particular be a plastic injection-molded part.

Durch die einteilige Ausführung des Trägers, der Verbindungselemente und der Halteleiste wird die Anzahl der für die Herstellung der Dichtung notwendigen Teile reduziert. Das hat Vorteile für die Herstellung der Dichtung. Durch die Verwendung eines einfach herzustellenden Teils, das einen großen Teil der bei einer herkömmlichen automatischen Dichtung allein für die Realisierung des Mechanismus zum Anheben und Absenken notwendigen Teile ersetzt, ist es möglich Kosten zu reduzieren.The one-piece design of the support, the connecting elements and the retaining strip reduces the number of parts required to manufacture the seal. This has advantages for the manufacture of the seal. By using a part that is easy to manufacture and which replaces a large part of the parts required in a conventional automatic seal just to create the mechanism for raising and lowering, it is possible to reduce costs.

Die aus dem Dokument US 5 454 192 A bekannte Dichtung weist neben dem Teil, das von dem Träger, den ersten Verbindungselementen und der Halteleiste gebildet wird, weitere Elemente auf, nämlich zumindest ein Dichtungsprofil oder -element als weiteres Element der Dichtungsleiste und eine Abdeckung, die den Träger und die Verbindungselemente und in der Freigabestellung auch die Dichtungsleiste abdeckt. Zumindest diese beiden Elemente müssen zu Herstellung einer Dichtung mit dem von dem Träger, den Verbindungselemente und der Halteleiste gebildeten Teil verbunden werden.The information contained in the document US 5 454 192 A known seal comprises, in addition to the part formed by the carrier, the first connecting elements and the retaining strip, further elements, namely at least one sealing profile or element as a further element of the sealing strip and a cover which covers the carrier and the connecting elements and, in the release position, also the sealing strip. At least these two elements must be connected to the part formed by the carrier, the connecting elements and the retaining strip in order to produce a seal.

Es könnte ein Nachteil der in dem Dokument US 5 454 192 A offenbarten Dichtung sein, dass die zur Betätigung der Dichtung notwendige Kraft dadurch in die Dichtung eingeleitet wird, dass die Halteleiste an einem Türrahmen anschlägt. Durch die dadurch begonnene Krafteinleitung bzw. Betätigung wird die Halteleiste aus ihrer Freigabestellung in die Dichtstellung bewegt, d.h. die Halteleiste bewegt sich bezüglich dem Türrahmen. Die Halteleiste oder ein womöglich an der Halteleiste befestigtes Anschlagelement, welches an dem Türrahmen anschlägt, schleift aufgrund der Relativbewegung zwischen dem Türrahmen und der Halteleiste über die Oberfläche des Türrahmens. Dieses Schleifen kann die Halteleiste bzw. das Anschlagelement oder den Türrahmen beschädigen. Außerdem kann der Druck des Türrahmens auf das Anschlagelement bzw. die Halteleiste so groß sein, dass eine Bewegung der Halteleiste relativ zum Türrahmen und auch zum Träger behindert ist.It could be a disadvantage of the document US 5 454 192 A disclosed seal may be that the force required to actuate the seal is introduced into the seal by the retaining strip striking a door frame. The force introduction or actuation thus initiated moves the retaining strip from its release position into the sealing position, i.e. the retaining strip moves relative to the door frame. The retaining strip or a stop element possibly attached to the retaining strip which strikes the door frame drags over the surface of the door frame due to the relative movement between the door frame and the retaining strip. This dragging can damage the retaining strip or the stop element or the door frame. In addition, the pressure of the door frame on the stop element or the retaining strip can be so great that movement of the retaining strip relative to the door frame and also to the support is hindered.

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

Der Erfindung liegt die Aufgabe zu Grunde eine einfache, aus wenig Teilen zusammengesetzte Dichtung vorzuschlagen, bei der die Probleme der bekannten Dichtung nicht auftreten können.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass

  • die Dichtung ein zweites Verbindungselement und ein Kraftübertragungselement aufweist, das in einer Längsrichtung des Trägers verschiebbar im Träger oder am Träger gelagert ist,
  • dass ein erstes Ende des ersten Verbindungselements mit dem verschiebbaren Kraftübertragungselement verbunden ist und ein zweites Ende des ersten Verbindungselementes mit der Halteleiste verbunden ist und
  • dass ein erstes Ende des zweiten Verbindungselementes an dem Träger und ein zweites Ende des zweiten Verbindungselementes an der Halteleiste befestigt ist und
  • dass das zweite Verbindungselement und das Kraftübertragungselement ebenfalls Bestandteile des zweiten Teils sind.
The invention is based on the object of proposing a simple seal composed of few parts in which the problems of the known seal cannot occur.
This object is achieved according to the invention in that
  • the seal has a second connecting element and a force transmission element which is arranged in a longitudinal direction of the carrier is mounted in the carrier or on the carrier,
  • that a first end of the first connecting element is connected to the displaceable force transmission element and a second end of the first connecting element is connected to the retaining strip and
  • that a first end of the second connecting element is attached to the carrier and a second end of the second connecting element is attached to the retaining strip and
  • that the second connecting element and the force transmission element are also components of the second part.

Bei einer erfindungsgemäßen Dichtung ist ein Kraftübertragungselement vorgesehen, dass zwar ein Bestandteil des zweiten Teils ist, zugleich aber auch in dem ersten Teil verschiebbar angeordnet ist. Dieses Kraftübertragungselement kann nun dazu genutzt werden, eine Kraft in die Dichtung aufzunehmen und in der Dichtung weiter zu leiten, damit sie in der Dichtung zum Bewegen der der Dichtungsleiste aus der Freigabestellung in die Dichtstellung genutzt werden kann. Das Kraftübertragungselement ist nicht an der Dichtungsleiste angebracht und auch nicht mit der Dichtungsleiste aus deren Freigabestellung in deren Dichtstellung und umgekehrt bewegbar. Die genannten Nachteile der aus dem Dokument US 5 454 192 A bekannten Dichtung können somit nicht auftreten. Gegenüber einer herkömmlichen automatischen Bodendichtung, wie zum Beispiel einer aus dem Dokument DE 20 2011 001 104 U1 bekannten Dichtung, unterscheidet sich die erfindungsgemäße Dichtung übrigens durch die geringe Anzahl von Teilen, die benötigt werden um eine funktionsfähige Dichtung zu erhalten. Im Wesentlichen wird ein erstes und ein zweites Teil benötigt. Durch zusätzliche erste und zusätzliche zweite Teile, kann die Dichtung verlängert werden.In a seal according to the invention, a force transmission element is provided which is a component of the second part, but is also arranged to be displaceable in the first part. This force transmission element can now be used to absorb a force in the seal and to transmit it further in the seal so that it can be used in the seal to move the sealing strip from the release position to the sealing position. The force transmission element is not attached to the sealing strip and cannot be moved with the sealing strip from its release position to its sealing position and vice versa. The disadvantages mentioned in the document US 5 454 192 A known seal cannot occur. Compared to a conventional automatic floor seal, such as one from the document DE 20 2011 001 104 U1 The seal according to the invention differs from the known seal by the small number of parts required to obtain a functional seal. Essentially, a first and a second part is required. The seal can be extended by using additional first and second parts.

Das erste Verbindungselement und/oder das zweite Verbindungselement einer erfindungsgemäßen Dichtung, die Verbindung zwischen dem Träger und dem ersten Ende des ersten Verbindungselementes, die Verbindung zwischen dem zweiten Ende des ersten Verbindungselementes und der Halteleiste, die Verbindung zwischen dem ersten Ende des zweiten Verbindungselementes und dem Träger und/oder die Verbindung zwischen dem zweiten Ende des zweiten Verbindungselementes und der Halteleiste können flexibel sein. Durch die Flexibilität ist es möglich, dass in den genannten Elementen bzw. Verbindungen eine Kraft gespeichert ist, die gebraucht wird, um nach einer Betätigung der Dichtung und einer Bewegung der Dichtungsleiste aus der Freigabestellung in die Dichtstellung, die für die Rückbewegung der Dichtungsleiste aus der Dichtstellung in die Freigabestellung benötigt wird.The first connecting element and/or the second connecting element of a seal according to the invention, the connection between the carrier and the first end of the first connecting element, the connection between the second end of the first connecting element and the retaining strip, the connection between the first end of the second connecting element and the carrier and/or the connection between the second end of the second connecting element and the retaining strip can be flexible. The flexibility makes it possible for a force to be stored in the elements or connections mentioned, which force is needed for the return movement of the sealing strip from the sealing position to the release position after the seal has been actuated and the sealing strip has moved from the release position to the sealing position.

Das erste und/oder das zweite Teil, welches das Kraftübertragungselement, das erste Verbindungselement, das zweite Verbindungselement und die Halteleiste als Bestandteile hat, kann aus Kunststoff hergestellt sein und insbesondere ein Kunststoffspritzgussteil sein.The first and/or the second part, which has the force transmission element, the first connecting element, the second connecting element and the retaining strip as components, can be made of plastic and in particular be a plastic injection-molded part.

Das Kraftübertragungselement einer erfindungsgemäßen Dichtung kann ein Fenster aufweisen, durch das das erste Ende des zweiten Verbindungselementes hindurchgreift oder in dem das erste Ende des zweiten Verbindungselementes angeordnet ist. Das durch das Fenster hindurchgreifende Ende des zweiten Verbindungselementes kann so, ohne dass die Verschiebbarkeit des Kraftübertragungselementes beeinträchtigt wird, an dem ersten Teil befestigt werden. Dazu kann in dem Ende und in dem ersten Teil ein Loch vorgesehen sein, in dem ein Knopf oder Niet oder dergleichen angeordnet ist, der die beiden Elemente miteinander verbindet.The force transmission element of a seal according to the invention can have a window through which the first end of the second connecting element extends or in which the first end of the second connecting element is arranged. The end of the second connecting element extending through the window can thus be attached to the first part without affecting the displaceability of the force transmission element. For this purpose, a A hole may be provided in which a button or rivet or the like is arranged, which connects the two elements together.

Der Träger kann einen in seiner Längsrichtung verlaufenden Führungskanal aufweisen, in dem das Kraftübertragungselement verschiebbar angeordnet ist.The carrier can have a guide channel extending in its longitudinal direction in which the force transmission element is slidably arranged.

Bei einer erfindungsgemäßen Dichtung kann das Dichtungselement ein Bestandteil des zweiten Teils sein. Das zweite Teil kann aus mehreren unterschiedlich harten und/oder flexiblen Kunststoffkomponenten bestehen.In a seal according to the invention, the sealing element can be a component of the second part. The second part can consist of several plastic components of different hardness and/or flexibility.

Eine erfindungsgemäße Dichtung kann wenigstens zwei Paare aus je einem ersten Teil und je einem zweiten Teil aufweisen, nämlich das erste Paar und ein letztes Paar. Das erste Teil des letzten Paares und das zweite Teil des letzten Paares weist die gleichen, insbesondere im Anspruch 1 genannten Merkmale auf, wie die Teile des ersten Paares. Das erste Teil und das zweite Teil des letzten Paares können identisch oder in Teilen identisch zu den Teilen des ersten oder letzten Paares sein.A seal according to the invention can have at least two pairs each consisting of a first part and a second part, namely the first pair and a last pair. The first part of the last pair and the second part of the last pair have the same features, in particular as mentioned in claim 1, as the parts of the first pair. The first part and the second part of the last pair can be identical or partially identical to the parts of the first or last pair.

Es kann ein zweites Ende des Trägers des ersten Paares mit einem ersten Ende des Trägers des letzten Paares verbunden sein und ein zweites Ende des Kraftübertragungsmittels des ersten Paares kann mit einem ersten Ende des Kraftübertragungsmittels des letzten Paares verbunden sein. Außerdem kann ein zweites Ende der Halteleiste des ersten Paares mit einem ersten Ende der Halteleiste des letzten Paares verbunden sein.A second end of the support of the first pair may be connected to a first end of the support of the last pair, and a second end of the force transmission means of the first pair may be connected to a first end of the force transmission means of the last pair. In addition, a second end of the retaining bar of the first pair may be connected to a first end of the retaining bar of the last pair.

Eine erfindungsgemäße Dichtung kann neben dem ersten und dem letzten Paar weitere Paare von ersten und zweiten Teilen aufweisen, die zwischen dem ersten Paar und dem letzten Paar angeordnet sind. Das erste Teil des weiteren Paares und das zweite Teil des weiteren Paares weisen die gleichen, insbesondere im Anspruch 1 genannten Merkmale auf, wie die Teile des ersten Paares oder des letzten Paares. Die ersten Teile und die zweiten Teile der weiteren Paare können identisch oder in Teilen identisch zu den Teilen des ersten oder des letzten Paares sein.A seal according to the invention may comprise, in addition to the first and last pairs, further pairs of first and second parts arranged between the first pair and the last pair. The first part of the further pair and the second Parts of the further pair have the same features, in particular as mentioned in claim 1, as the parts of the first pair or the last pair. The first parts and the second parts of the further pairs can be identical or partially identical to the parts of the first or the last pair.

Dann ist es möglich,

  1. a. dass die ersten und zweiten Teile des ersten Paares und des weiteren Paares oder der weiteren Paare gleich sind,
  2. b. dass die ersten und zweiten Teile des letzten Paares und des weiteren Paares oder der weiteren Paare gleich sind oder
  3. c. dass die ersten Teile des ersten Paares und des weiteren Paares oder der weiteren Paare gleich sind und die zweiten Teile des letzten Paares und des weiteren Paares oder der weiteren Paare gleich sind.
Then it is possible
  1. a. that the first and second parts of the first pair and the further pair or pairs are equal,
  2. b. that the first and second parts of the last pair and the further pair or pairs are equal, or
  3. c. that the first parts of the first pair and the further pair or pairs are equal and the second parts of the last pair and the further pair or pairs are equal.

Eine erfindungsgemäße Dichtung kann ein Anschlagelement aufweisen, das von dem ersten Ende des Kraftübertragungselementes des zweiten Teils des ersten Paares gebildet ist oder als ein- oder mehrteiliges Bauteil vorgesehen ist, das mit dem ersten Ende des Kraftübertragungselementes verbunden ist.A seal according to the invention can have a stop element which is formed by the first end of the force transmission element of the second part of the first pair or is provided as a one- or multi-part component which is connected to the first end of the force transmission element.

Eine erfindungsgemäße Dichtung kann Befestigungselemente, zum Beispiel Befestigungswinkel, aufweisen, die mit dem ersten Ende des Trägers des ersten Paares einerseits und entweder mit dem zweiten Ende des Trägers des ersten Paares oder ggf. des letzten Paares andererseits verbunden sind. Die Befestigungswinkel können mit einem Schenkel in den Führungskanal eingesteckt sein und mit einem zweiten Schenkel an einem Türblatt angebracht werden.A seal according to the invention can have fastening elements, for example fastening angles, which are connected to the first end of the support of the first pair on the one hand and either to the second end of the support of the first pair or possibly the last pair on the other hand. The fastening angles can be inserted into the guide channel with one leg and attached to a door leaf with a second leg.

Es ist nicht notwendig, dass eine erfindungsgemäße Vorrichtung alle nachfolgend beschriebenen Merkmale aufweist. Es ist auch möglich, dass eine erfindungsgemäße Vorrichtung nur einzelne Merkmale des nachfolgend beschriebenen Ausführungsbeispiels aufweist.It is not necessary for a device according to the invention to have all of the features described below. It is also possible for a device according to the invention to have only individual features of the exemplary embodiment described below.

Die in der Fig. 1 dargestellte erfindungsgemäße Dichtung ist aus drei Paaren, nämlich einem ersten Paar 1a, 2a, einem weiteren Paar 1b, 2b und einem letzten Paar 1c, 2c, einem Anschlagselement 3, zwei Befestigungswinkeln 4 und drei Befestigungsknöpfen 5 zusammengesetzt. Jedes der drei Paare 1a, 2a; 1b, 2b; 1c, 2c weist ein erstes Teil 1a, 1b, 1c und ein zweites Teil 2a, 2b, 2c auf. Diese ersten Teile 1a, 1b, 1c sind soweit wie möglich identisch. Zwischen dem ersten Teil 1a des ersten Paares und dem ersten Teil 1b des weiteren Paares gibt es einen geringfügigen Unterschied. Das erste Teil 1c des letzten Paares unterschiedet sich von den ersten Teilen 1a, 1b des ersten Paares und des weiteren Paares ebenfalls geringfügig. Auf die Unterschiede wird noch eingegangen. Auch die zweiten Teile 2a, 2b, 2c sind soweit wie möglich identisch. Zwischen den zweiten Teilen 2a, 2b des ersten Paares und des weiteren Paares gibt es keinen Unterschied. Das zweite Teil 2c des letzten Paares unterschiedet sich von den zweiten Teilen 2a, 2b des ersten Paares und des weiteren Paares geringfügig, worauf ebenfalls noch eingegangen wird.The Fig.1 The seal according to the invention shown is composed of three pairs, namely a first pair 1a, 2a, a further pair 1b, 2b and a last pair 1c, 2c, a stop element 3, two fastening angles 4 and three fastening buttons 5. Each of the three pairs 1a, 2a; 1b, 2b; 1c, 2c has a first part 1a, 1b, 1c and a second part 2a, 2b, 2c. These first parts 1a, 1b, 1c are as identical as possible. There is a slight difference between the first part 1a of the first pair and the first part 1b of the further pair. The first part 1c of the last pair also differs slightly from the first parts 1a, 1b of the first pair and the further pair. The differences will be discussed later. The second parts 2a, 2b, 2c are also as identical as possible. There is no difference between the second parts 2a, 2b of the first pair and the next pair. The second part 2c of the last pair differs slightly from the second parts 2a, 2b of the first pair and the next pair, which will also be discussed later.

Die ersten Teile 1a, 1b, 1c haben in einer Längsrichtung der Dichtung ein nahezu gleichförmiges, im Wesentlichen U-förmiges Profil mit einem Steg 10 und zwei sich daran anschließenden Schenkeln 11. Mit geringem Abstand zum Steg 10 und im Wesentlichen parallel zu diesem Steg 10 ragt von den Schenkeln 11 je ein Führungssteg 12 nach innen. Der Steg 10, die Schenkel 11 und die Führungsstege 12 bilden einen Führungskanal. Der Führungskanal könnte auch durch andere Elemente gebildet sein.The first parts 1a, 1b, 1c have in a longitudinal direction of the seal a nearly uniform, essentially U-shaped profile with a web 10 and two adjoining Legs 11. A guide web 12 projects inwards from each leg 11 at a short distance from the web 10 and essentially parallel to this web 10. The web 10, the legs 11 and the guide webs 12 form a guide channel. The guide channel could also be formed by other elements.

An einem ersten Ende der ersten Teile 1a, 1b, 1c der Paare 1a, 2a; 1b, 2b; 1c, 2c sind auf Außenseiten der Schenkel 11 zwei erste Befestigungsstrukturen 13 vorgesehen. Diese werden durch je eine Vertiefung 130 und je einen Vorsprung 131 gebildet, der in der Vertiefung 130 angeordnet ist. Die Vertiefungen 130 reichen bis an den Rand der Schenkel 11. Statt der Vertiefungen 130 und der Vorsprünge 131 könnten auch andere erste Befestigungsstrukturen vorgesehen sein.At a first end of the first parts 1a, 1b, 1c of the pairs 1a, 2a; 1b, 2b; 1c, 2c, two first fastening structures 13 are provided on the outside of the legs 11. These are formed by a recess 130 and a projection 131 each, which is arranged in the recess 130. The recesses 130 extend to the edge of the legs 11. Instead of the recesses 130 and the projections 131, other first fastening structures could also be provided.

An dem zweiten Ende der ersten Teile 1a, 1b des ersten Paares 1a, 2a und des weiteren Paares 1b, 2b sind an den Schenkeln11 je eine zweite Befestigungsstruktur 14 vorgesehen. Diese zweite Befestigungsstruktur wird durch eine Lasche 14 gebildet, die sich den Schenkeln 11 anschließt. Jede der Laschen 14 weist ein Durchgangsloch 140 auf. Die Lasche 14 hat in etwa die gleichen äußeren Abmessungen wie die Vertiefung 130 und das Loch 140 hat in der Lasche 14 in etwa die gleiche Position wie der Vorsprung 131 in der Vertiefung. Anstelle der Laschen 14 könnten auch andere zweite Befestigungsstrukturen vorgesehen sein, die komplementär zu den ersten Befestigungsstrukturen sind und mit diesen zusammenwirken können.At the second end of the first parts 1a, 1b of the first pair 1a, 2a and the further pair 1b, 2b, a second fastening structure 14 is provided on each of the legs 11. This second fastening structure is formed by a tab 14 that adjoins the legs 11. Each of the tabs 14 has a through hole 140. The tab 14 has approximately the same external dimensions as the recess 130 and the hole 140 has approximately the same position in the tab 14 as the projection 131 in the recess. Instead of the tabs 14, other second fastening structures could also be provided that are complementary to the first fastening structures and can interact with them.

An dem ersten Ende der ersten Teile 1b, 1c des weiteren Paares 1b, 2b und des letzten Paares 1c, 2c schließen sich an den Steg 10 jeweils eine Lasche als dritte Befestigungsstruktur 15 an. Diese Lasche 15 weist ein Durchgangsloch 150 auf. Anstelle der Lasche 15 könnte auch eine andere dritte Befestigungsstruktur vorgesehen sein.At the first end of the first parts 1b, 1c of the further pair 1b, 2b and the last pair 1c, 2c, a tab as a third fastening structure 15 is connected to the web 10. This tab 15 has a through hole 150. Instead of the Tab 15 could also be provided with another third fastening structure.

An einem zweiten Ende der ersten Teile 1a, 1b, 1c weisen die Stege 10 je eine vierte Befestigungsstruktur 16 auf, die durch eine Vertiefung 160 und einen in der Vertiefung vorgesehenen Vorsprung 161 gebildet ist. Die Vertiefung 160 reicht bis zum Rand des Stegs 10. Die Vertiefung 160 hat in etwa die gleichen äußeren Abmessungen wie die Lasche 15 und der Vorsprung 161 ist so in der Vertiefung 160 angeordnet, dass seine Lage der Lage des Loches 150 in der Lasche 15 entspricht. Anstelle der Vertiefung 160 und dem Vorsprung 161 kann auch eine andere vierte Befestigungsstruktur vorgesehen sein, die komplementär zur dritten Befestigungsstruktur ist und mit dieser zusammenwirkt.At a second end of the first parts 1a, 1b, 1c, the webs 10 each have a fourth fastening structure 16, which is formed by a recess 160 and a projection 161 provided in the recess. The recess 160 extends to the edge of the web 10. The recess 160 has approximately the same external dimensions as the tab 15 and the projection 161 is arranged in the recess 160 such that its position corresponds to the position of the hole 150 in the tab 15. Instead of the recess 160 and the projection 161, another fourth fastening structure can also be provided which is complementary to the third fastening structure and interacts with it.

Die zweiten Befestigungsstrukturen 14 an den zweiten Enden des ersten Teils 1a des ersten Paares 1a, 2a, die erste Befestigungsstruktur 13 an dem ersten Ende des ersten Teils 1b des weiteren Paares 1b, 2b und die vierten Befestigungsstrukturen 16 an dem zweiten Ende der ersten Teile 1a des ersten Paares 1a, 2a und die dritten Befestigungsstrukturen 15 an dem ersten Ende des ersten Teils 1b des weiteren Paares 1b, 2b sind komplementär zueinander. Das erste Teil 1a des ersten Paares 1a, 2a und das erste Teil 1b des weiteren Paares 2a, 2b sind über diese Befestigungsstrukturen miteinander verbunden.The second fastening structures 14 at the second ends of the first part 1a of the first pair 1a, 2a, the first fastening structure 13 at the first end of the first part 1b of the further pair 1b, 2b and the fourth fastening structures 16 at the second end of the first parts 1a of the first pair 1a, 2a and the third fastening structures 15 at the first end of the first part 1b of the further pair 1b, 2b are complementary to one another. The first part 1a of the first pair 1a, 2a and the first part 1b of the further pair 2a, 2b are connected to one another via these fastening structures.

Die zweiten Befestigungsstrukturen 14 an dem zweiten Enden des ersten Teils 1b des weiteren Paares 1b, 2b die erste Befestigungsstruktur 13 an dem ersten Ende des ersten Teils 1c des letzten Paares 1c, 2c und die vierten Befestigungsstrukturen 16 an dem zweiten Ende der ersten Teile 1b des weiteren Paares 1a, 2a und die dritten Befestigungsstrukturen 15 an dem ersten Ende der ersten Teils 1c des letzten Paares 1c, 2c sind komplementär zueinander. Der erste Teil 1b des weiteren Paares 1b, 2b und das erste Teil 1c des letzten Paares 2c, 2c sind über diese Befestigungsstrukturen miteinander verbunden.The second fastening structures 14 at the second end of the first part 1b of the further pair 1b, 2b, the first fastening structure 13 at the first end of the first part 1c of the last pair 1c, 2c and the fourth fastening structures 16 at the second end of the first parts 1b of the further pair 1a, 2a and the third fastening structures 15 at the first end of the first part 1c of the last pair 1c, 2c are complementary to each other. The The first part 1b of the further pair 1b, 2b and the first part 1c of the last pair 2c, 2c are connected to each other via these fastening structures.

Vorstehend ist beschrieben, dass nur der erste Teil 1b des weiteren Paares 1b, 2b alle Befestigungsstrukturen 13, 14, 15, 16 aufweist. Den anderen ersten Teilen 1a, 1c fehlen entweder die Lasche am ersten Ende oder die Laschen am zweiten Ende. Damit die ersten Teile trotz dieser Unterschiede kostengünstig hergestellt werden können, zum Beispiel als Kunststoffspritzgussteil, ist es möglich, zunächst nur erste Teile für weitere Paare herzustellen und dann durch entfernen der Laschen am ersten Ende oder durch Entfernen der Laschen am zweiten Ende aus den ersten Teilen für weitere Paare erste Teile für erste oder letzte Paare herzustellen.It is described above that only the first part 1b of the further pair 1b, 2b has all fastening structures 13, 14, 15, 16. The other first parts 1a, 1c are missing either the tab at the first end or the tabs at the second end. So that the first parts can be manufactured cost-effectively despite these differences, for example as a plastic injection-molded part, it is possible to initially only manufacture first parts for further pairs and then to manufacture first parts for first or last pairs from the first parts for further pairs by removing the tabs at the first end or by removing the tabs at the second end.

Die zweiten Teile 2a, 2b, 2c umfassen mehrere Bestandteile nämlich ein Dichtungselement 20 und eine Halteleiste 21, die zusammen eine Dichtungsleiste bilden. Des Weiteren sind als Bestandteile ein erstes Verbindungselement 22, ein zweites Verbindungselement 23 und ein Kraftübertragungselement 24 auf.The second parts 2a, 2b, 2c comprise several components, namely a sealing element 20 and a retaining strip 21, which together form a sealing strip. Furthermore, a first connecting element 22, a second connecting element 23 and a force transmission element 24 are present as components.

Die Halteleiste 21 der zweiten Teile 2a, 2b 2c ist eine im Querschnitt im Wesentlichen rechteckige Stange, an deren Seitenwänden das im Querschnitt U-förmiges Dichtungselement 20 befestigt ist.The retaining strip 21 of the second parts 2a, 2b 2c is a rod with a substantially rectangular cross-section, to the side walls of which the sealing element 20 with a U-shaped cross-section is fastened.

An einem ersten Ende sind an der Halteleiste 21 des zweiten Teils 2a, 2b, 2c des ersten Paares 1a, 2a, des weiteren Paares 1b, 2b und des letzten Paares 1c, 2c fünfte Befestigungsstrukturen 25 vorgesehen und zwar auf einer Oberseite und einer Unterseite der Halteleiste 21. Auf diesen fünften Befestigungsstrukturen 25 sind Vertiefungen 250 und Vorsprünge 251 gebildet, die in den Vertiefungen angeordnet sind. Anstelle der Vertiefungen 250 und Vorsprünge 251 können auch andere fünfte Befestigungsstrukturen vorgesehen sein.At a first end, fifth fastening structures 25 are provided on the retaining strip 21 of the second part 2a, 2b, 2c of the first pair 1a, 2a, the further pair 1b, 2b and the last pair 1c, 2c, namely on an upper side and a lower side of the retaining strip 21. Recesses 250 and projections 251 are formed on these fifth fastening structures 25, which are arranged in the recesses. Instead of the recesses 250 and Projections 251 may also include other fifth fastening structures.

An einem zweiten Ende sind an der Halteleiste 22 des zweiten Teils 2a, 2b des ersten Paares 1a, 2a und des weiteren Paares 1b, 2b sechste Befestigungsstrukturen 26 vorgesehen. Diese sind durch Laschen 26 gebildet, die sich an der Oberseite und Unterseite an die Halteleiste anschließen. Jeder der beiden Laschen 26 hat ein Durchgangsloch 260. Die Laschen 26 mit dem Loch 260 sind komplementär zu den Vertiefungen 250 und den Vorsprüngen 251 gestaltet. Anstelle der Laschen 26 können auch andere sechste Befestigungsstrukturen vorgesehen sein, die komplementär zu den fünften Befestigungsstrukturen sind und mit diesen zusammenwirken.At a second end, sixth fastening structures 26 are provided on the retaining strip 22 of the second part 2a, 2b of the first pair 1a, 2a and the further pair 1b, 2b. These are formed by tabs 26 that are connected to the retaining strip at the top and bottom. Each of the two tabs 26 has a through hole 260. The tabs 26 with the hole 260 are designed to be complementary to the recesses 250 and the projections 251.
