Description

Die vorliegende Erfindung betrifft eine automatische Türdichtung mit einem Träger, Verbindungselemente und einer Dichtungsleiste umfassend ein Dichtungselement, wobei der Träger und die Verbindungselemente durch ein Teil gebildet sind.The present invention relates to an automatic door seal with a carrier, connecting elements and a sealing strip comprising a sealing element, the carrier and the connecting elements being formed by one part.

Das Dokument US 5 454 192 A offenbart eine automatische Dichtung für eine Tür, die einen an der Tür anbringbaren Träger, an dem Träger befestigte Verbindungselemente und eine von den Verbindungselementen getragene Dichtungsleiste aufweist. An der Halteleiste ist ein Dichtungselement befestigt. Die Halteleiste und das Dichtungselement bilden zusammen eine Dichtungsleiste.The document US 5,454,192 A discloses an automatic seal for a door, comprising a carrier attachable to the door, fasteners attached to the carrier, and a weatherstrip carried by the fasteners. A sealing element is attached to the retaining strip. The retaining strip and the sealing element together form a sealing strip.

Die Vielzahl von Verbindungselementen koppeln die Dichtungsleiste und den Träger und halten die Dichtungsleiste in einer Freigabestellung, wobei die Dichtungsleiste 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 Dichtungselement an der Gegenfläche schleift.The plurality of connecting elements couple the sealing strip and the carrier and hold the sealing strip in a release position, the sealing strip in the release position being at a distance from a mating 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 rubbing on the mating surface.

Die Verbindungselemente sind flexibel und/oder die Verbindung zwischen den Verbindungselementen und dem Träger und der Dichtungsleiste sind flexibel. Die 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 Dichtungsleiste in der Längsrichtung der Dichtungsleiste ausgeübt werden.The connecting elements are flexible and/or the connection between the connecting elements and the carrier and the sealing strip are flexible. The 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. For this purpose, a force can be exerted on the sealing strip in the longitudinal direction of the sealing strip.

Zur Betätigung der Dichtung kann damit eine Kraft in die Dichtungsleiste eingeleitet werden, die die Dichtungsleiste in eine Dichtstellung drückt, in der die Dichtungsleiste 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 sealing strip, which presses the sealing strip into a sealing position in which the sealing strip is pressed against the counter surface, for example a floor, a ceiling, a wall, a threshold or a frame part of a door frame is used to seal the door.

In verschiedenen Ausführungsformen der in dem Dokument US 5 454 192 A offenbarten Dichtung können die Verbindungselemente mit dem Träger und mit einer der Dichtungsleisten, nämlich einer Halteleiste ein Teil bilden. Bei diesem Teil kann es sich insbesondere um ein Kunststoffspritzgussteil handeln.In various embodiments the in the document US 5,454,192 A disclosed seal, the connecting elements can form a part with the carrier and with one of the sealing strips, namely a 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 carrier, the connecting elements and the retaining strip reduces the number of parts required to produce the seal. This has advantages for the production of the seal. By using an easy-to-manufacture part that replaces a large part of the parts necessary in a conventional automatic seal just for realizing the raising and lowering mechanism, it is possible to reduce costs.

Die aus dem Dokument US 5 454 192 A bekannte Dichtung weist neben dem den Träger, die Verbindungselemente und die Halteleiste bildenden Teil weitere Teil auf, nämlich zumindest ein Dichtungsprofil oder -element als weiteren Teil der Dichtungsleiste und eine Abdeckung, die den Träger und die Verbindungselemente und in der Freigabestellung auch die Dichtungsleiste abdeckt. Zumindest diese beiden Teile müssen zu Herstellung einer Dichtung mit dem den Träger, die Verbindungselemente und die Halteleiste bildenden Teil verbunden werden.The one from the document US 5,454,192 A In addition to the part forming the carrier, the connecting elements and the retaining strip, the known seal has further parts, namely at least one sealing profile or element as a further part of the sealing strip and a cover which covers the carrier and the connecting elements and also the sealing strip in the release position. At least these two parts must be connected to the part forming the carrier, the connecting elements and the retaining strip in order to produce a seal.

Hier setzt die Erfindung an.This is where the invention comes into play.

Der Erfindung lag die Aufgabe zu Grunde, eine Dichtung der eingangs genannter Art so zu verbessern, dass der Montageaufwand zur Herstellung der Dichtung reduziert ist.The invention was based on the object of improving a seal of the type mentioned in such a way that the assembly effort required to produce the seal is reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Dichtung eine Abdeckung und eine Dichtungsleiste einschließlich eines Dichtungselementes aufweist, und zumindest entweder die Abdeckung oder das Dichtungselement oder die Abdeckung und das Dichtungselement zusammen mit dem Träger, den Verbindungselementen und der Halteleiste ein Teil bilden. Auch dieses eine Teil kann vorzugsweise ein Kunststoffspritzgussteil sein. Das Teil kann aus einer Komponente, zwei Komponenten oder mehr Komponenten hergestellt sein, wodurch sich in unterschiedlichen Bereichen des Teils unterschiedliche Materialeigenschaften realisieren lassen. So kann das Dichtungselement aus einer Komponente aus einem elastischen Material hergestellt sein, welches als Dichtungsmaterial gut geeignet ist. Ein Bereich der Dichtungsleiste, der die Funktion der Halteleiste hat, und/oder der Träger und/oder die Verbindungselemente und/oder die Abdeckung hingegen können aus einem gegenüber dem elastischen Material härterem Material hergestellt sein, um die Festigkeit zu geben, die für die Zweckbestimmung dieser Elemente sinnvoll oder notwendig ist. Bereiche zwischen den Elementen aus hartem Material, insbesondere zwischen dem Träger und den Verbindungselementen, den Verbindungselementen und der Halteleiste und dem Träger und der Abdeckung können aus einem weichen und/oder elastischen Material hergestellt sein. Es ist auch möglich, dass in einen Bereich der Dichtungsleiste und/oder in die Verbindungselemente und/oder in den Träger und/oder in die Abdeckung Elemente aus einem harten Material, zum Beispiel eine Armierung eingebettet sind. Eine solche Einbettung könnte zum Beispiel durch Umspritzen hergestellt sein.This object is achieved according to the invention in that the seal has a cover and a sealing strip including a sealing element, and at least either the cover or the sealing element or the cover and the sealing element together with the carrier, the connecting elements and the retaining strip form a part. This one part can also preferably be a plastic injection molded part. The part can be made from one component, two components or more components, which allows different material properties to be achieved in different areas of the part. The sealing element can thus be made from a component made of an elastic material, which is well suited as a sealing material. An area of the sealing strip, which has the function of the retaining strip, and / or the carrier and / or the connecting elements and / or the cover, on the other hand, can be made of a material that is harder than the elastic material in order to provide the strength necessary for the intended purpose of these elements makes sense or is necessary. Areas between the elements made of hard material, in particular between the carrier and the connecting elements, the connecting elements and the retaining strip and the carrier and the cover can be made of a soft and / or elastic material. It is also possible for elements made of a hard material, for example reinforcement, to be embedded in an area of the sealing strip and/or in the connecting elements and/or in the carrier and/or in the cover. Such an embedding could be produced, for example, by overmolding.

Es ist nicht notwendig, dass eine erfindungsgemäße Dichtung alle nachfolgend beschriebenen Merkmale aufweist. Es ist auch möglich, dass eine erfindungsgemäße Vorrichtung nur einzelne Merkmale der nachfolgend beschriebenen Ausführungsbeispiele aufweist.It is not necessary for a seal 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 embodiments described below.

Das in den Figuren 1 bis 4 dargestellte Kunststoffspritzgussteil kann zur Herstellung einer erfindungsgemäßen Dichtung verwendet werden. Eine solche erfindungsgemäße Dichtung ist mit der Dichtungsleiste in der Freigabestellung in den Figuren 1a bis 4a und mit der Dichtungsleiste in der Dichtstellung in den Figuren 1b bis 4b dargestellt.That in the Figures 1 to 4 Plastic injection molded part shown can be used to produce a seal according to the invention. Such a seal according to the invention is in the release position with the sealing strip Figures 1a to 4a and with the sealing strip in the sealing position Figures 1b to 4b shown.

Das Kunststoffspritzgussteil weist einen Träger 1, Abdeckungen 2, Verbindungselemente 3 und eine Dichtungsleiste 4 auf. Eine Halteleiste und ein Dichtungselement, wie man sie von andere automatischen Türdichtungen kennt, sind integrale Bestandteile der Dichtungsleiste.The plastic injection molded part has a carrier 1, covers 2, connecting elements 3 and a sealing strip 4. A retaining strip and a sealing element, as known from other automatic door seals, are integral parts of the sealing strip.

Der Träger 1 ist ebenso wie die Abdeckungen und ein mittlerer Bereich 41 und Randbereiche 42 der Dichtungsleiste leistenförmig.The carrier 1, like the covers and a central area 41 and edge areas 42 of the sealing strip, is strip-shaped.

Der Träger 1 hat zwei Längsseiten. Jede der Längsseiten des Trägers 1 ist über ein Filmscharnier mit einer der beiden Abdeckungen 2 und zwar mit einer Längsseite der Abdeckungen 2 verbunden. Der Träger 1 und die Abdeckungen 2 liegen in einer Ebene.The carrier 1 has two long sides. Each of the long sides of the carrier 1 is connected to one of the two covers 2 via a film hinge, specifically to one long side of the covers 2. The carrier 1 and the covers 2 lie in one plane.

An einer Unterseite des Trägers 1 sind die Verbindungselemente 3 angebracht. Die Verbindungselemente 3 sind stabartig und haben ein erstes Ende und ein zweites Ende. Das erste Ende jedes Verbindungselementes 3 ist mit der Unterseite des Trägers 1 verbunden. Die Verbindungselemente 3 sind parallel und mit Abstand zueinander angeordnet und sie schließen mit dem Träger 1 einen Winkel zwischen 20° und 70° ein.The connecting elements 3 are attached to an underside of the carrier 1. The connecting elements 3 are rod-like and have a first end and a second end. The first end of each connecting element 3 is connected to the underside of the carrier 1. The connecting elements 3 are arranged parallel and at a distance from one another and they form an angle of between 20° and 70° with the carrier 1.

Die zweiten Enden der Verbindungselemente 3 sind mit der Dichtungsleiste 4 verbunden und zwar mit einer Oberseite des mittleren Bereichs 41 der Dichtungsleiste 4. Der mittlere Bereich 41 ist parallel zu dem Träger 1 angeordnet. Auch der mittlere Bereich 41 hat zwei Längsseiten. An jeder Längsseite ist über je ein Filmscharnier einer der leistenförmigen Randbereich 42 der Dichtungsleiste 4 angeschlossen. Die Randbereiche 42 kragen von dem mittleren Bereich 41 seitlich und leicht nach oben ausgerichtet aus.The second ends of the connecting elements 3 are connected to the sealing strip 4, specifically to an upper side of the central region 41 of the sealing strip 4. The central region 41 is arranged parallel to the carrier 1. The middle area 41 also has two long sides. One of the strip-shaped edge regions 42 of the sealing strip 4 is connected to each long side via a film hinge. The edge areas 42 protrude from the central area 41 laterally and slightly upwards.

Die Verbindungen zwischen dem Träger 1 und den Verbindungselementen 3 wie auch die Verbindungen zwischen den Verbindungselementen 3 und dem mittleren Bereich 41 sind flexibel und sie ermöglichen dadurch eine Drehung zwischen dem Träger 1 und den Verbindungselementen 3 einerseits und den Verbindungselementen 3 und der Dichtungsleiste 4 andererseits. Der Träger 1, die Verbindungselemente 3 und die Dichtungsleiste 4 bilden dadurch einen Parallellenker, das bedeutet, dass die Dichtungsleiste 4 und der Träger 1 parallel ausgerichtet relativ zueinander bewegt werden können, wobei sich der Abstand zueinander ändert. Gleichzeitig kommt es zu einer Längsverschiebung des Trägers 1 und der Dichtungsleiste 4.The connections between the carrier 1 and the connecting elements 3 as well as the connections between the connecting elements 3 and the central region 41 are flexible and they thereby enable rotation between the carrier 1 and the connecting elements 3 on the one hand and the connecting elements 3 and the sealing strip 4 on the other hand. The carrier 1, the connecting elements 3 and the sealing strip 4 thereby form a parallel link, which means that the sealing strip 4 and the carrier 1 can be moved relative to one another in a parallel alignment, with the distance from one another changing. At the same time, there is a longitudinal displacement of the carrier 1 and the sealing strip 4.

Die Dichtungsleiste 4 kann aus einem Material hergestellt sein, das elastischer und weicher ist als das Material aus dem insbesondere der Träger 1 und die Abdeckungen 2 und evtl. auch die Verbindungselemente hergestellt sind. Durch die Elastizität der Dichtungsleiste 4 kann eine gute Abdichtung erreicht werden. Die größere Steifigkeit oder Härte des Trägers 1 und der Verbindungselemente sind für eine gute Kraftübertragung und damit für das ermöglichen der Relativbewegung von Träger 1 und Dichtungsleiste 4 wichtig. Auch die Dichtungsleiste 4 braucht insbesondere in der Richtung, in der eine Kraft zur Bewegung der Dichtungsleiste 4 in die Dichtungsleiste 4 eingeleitet wird, eine Mindeststeifigkeit zur Kraftübertragung. Um diese gleichzeitig bei für die Dichteigenschaften wichtiger Flexibilität zu erreichen, könnte die Dichtungsleiste 4 aus einer weichen, flexiblen und einer harten, steifen Komponente hergestellt sein. Möglich ist auch die Herstellung aus einer weichen, flexiblen Komponente, die dann durch eine Armierung ausgesteift ist. Dazu kann zum Beispiel bei dem dargestellten Kunststoffspritzgussteil ein Draht oder Stab in die Dichtungsleiste 4 eingebettet sein. Diese Armierung kann einspritzt bzw. umspritzt sein oder nachträglich in die Dichtungsleiste 4 eingezogen sein.The sealing strip 4 can be made of a material that is more elastic and softer than the material from which the carrier 1 and the covers 2 and possibly also the connecting elements are made. Due to the elasticity of the Sealing strip 4 can achieve a good seal. The greater rigidity or hardness of the carrier 1 and the connecting elements are important for good force transmission and thus for enabling the relative movement of the carrier 1 and the sealing strip 4. The sealing strip 4 also needs a minimum rigidity for force transmission, particularly in the direction in which a force for moving the sealing strip 4 is introduced into the sealing strip 4. In order to achieve this at the same time with flexibility, which is important for the sealing properties, the sealing strip 4 could be made of a soft, flexible and a hard, rigid component. It is also possible to manufacture it from a soft, flexible component, which is then reinforced with reinforcement. For this purpose, for example, in the plastic injection molded part shown, a wire or rod can be embedded in the sealing strip 4. This reinforcement can be injected or overmolded or subsequently drawn into the sealing strip 4.

Aus diesem Kunststoffspritzgussteil können in wenigen Schritten die in den Figuren 1a bis 4a und 1b bis 4b dargestellten Dichtungen hergestellt werden. Dazu kann das Kunststoffspritzgussteil zunächst auf eine gewünschte Länge gebracht werden. Anschließend werden dann die Randbereiche 42 nach oben geschwenkt, bis sie in etwa 90° zu dem mittleren Bereich 41 stehen. Dann können die Abdeckungen 2 nach unten geschwenkt werden, bis diese in etwa 90° zu dem Träger 1 stehen. Die freien Seitenränder der Randbereiche 42 liegen dann an den nun innen liegenden Seitenflächen der Abdeckungen 2 an.This plastic injection molded part can be made into the in just a few steps Figures 1a to 4a and 1b to 4b Seals shown can be produced. To do this, the plastic injection molded part can first be brought to a desired length. The edge regions 42 are then pivoted upwards until they are approximately 90° to the central region 41. Then the covers 2 can be pivoted downwards until they are approximately 90° to the carrier 1. The free side edges of the edge regions 42 then rest on the now inner side surfaces of the covers 2.

Bei der in den Figuren 1a bis 4a dargestellten Dichtung schließen die freien Seitenränder der Abdeckungen 2 in etwa bündig mit einer Unterseite des mittleren Bereichs 41 der Dichtungsleiste 4 ab. Die Dichtungsleiste 4 dieser Dichtung ist dann in einem Raum zwischen dem Träger 1 und den Abdeckungen 2 aufgenommen und befindet sich in der Freigabestellung.At the in the Figures 1a to 4a In the seal shown, the free side edges of the covers 2 are approximately flush with an underside of the central region 41 of the sealing strip 4. The sealing strip 4 of this seal is then in a room recorded between the carrier 1 and the covers 2 and is in the release position.

Bei der in den Figuren 1b bis 4b dargestellten Dichtung sind durch eine Kraft, die in Längsrichtung auf die Dichtungsleiste 4 wirkt, der Winkel zwischen den Verbindungselementen 3 und dem Träger 1 und der Winkel zwischen den Verbindungselementen 3 und der Dichtungsleiste 4 vergrößert, wodurch der Abstand zwischen der Dichtungsleiste 4 und dem Träger 1 vergrößert ist. Dadurch wird die Dichtungsleiste 4 aus dem Raum zwischen dem Träger 1 und den Abdeckungen 2 herausbewegt und in die Dichtstellung gebracht, in der sie an einer Gegenfläche anliegen kann.At the in the Figures 1b to 4b Seal shown are increased by a force acting in the longitudinal direction on the sealing strip 4, the angle between the connecting elements 3 and the carrier 1 and the angle between the connecting elements 3 and the sealing strip 4, whereby the distance between the sealing strip 4 and the carrier 1 is enlarged. As a result, the sealing strip 4 is moved out of the space between the carrier 1 and the covers 2 and brought into the sealing position in which it can rest against a counter surface.

Die Kraft kann über einen Auslöser in eine erfindungsgemäße Dichtung eingeleitet werden. Dieser kann integraler Teil der Dichtungsleiste 4 sein. So kann zum Beispiel ein Ende 43 der Dichtungsleiste 4 als Auslöser dienen. Ebenso ist es möglich, dass bei der Dichtung ein besonderes Teil vorgesehen ist, das einen Auslöser bildet und das mit der Dichtungsleiste verbunden ist.The force can be introduced into a seal according to the invention via a trigger. This can be an integral part of the sealing strip 4. For example, one end 43 of the sealing strip 4 can serve as a trigger. It is also possible for the seal to have a special part that forms a trigger and is connected to the sealing strip.
