Description

Technisches GebietTechnical field

Die Erfindung betrifft eine absenkbare Türdichtung gemäss Oberbegriff des Patentanspruches 1.The invention relates to a lowerable door seal according to the preamble of claim 1.

Stand der TechnikState of the art

Eine gattungsgemässe Türdichtung als Schallschutz und als Schutz vor Zugluft ist aus EP-A-0'338'974 bekannt. Sie besteht im wesentlichen aus einer nach unten offenen, u-förmigen Führungsprofilschiene, einer relativ zur Führungsprofilschiene verschiebbaren Dichtleiste und einem Absenkmechanismus zum Absenken beziehungsweise Anhebung der Dichtleiste bei Schliessung beziehungsweise Öffnung der Türe. Der Absenkmechanismus ist in DE-A-195'16'530 beschrieben. Die Dichtleiste weist eine Trägerprofilschiene und ein einstückiges, im wesentlichen u-förmiges elastomeres Dichtungsprofil auf. Das Dichtungsprofil liegt im geschlossenen Zustand der Türe mit einer unteren Dichtlippe auf dem Boden auf. Ferner ist sie beidseitig an der Trägerprofilschiene befestigt, wobei sie Schenkel aufweist, welche über die Befestigungsstelle hinausragen und an Innenwänden der Führungsprofilschiene gleitend anliegen und seitliche Dichtlippen bilden. Da diese Anordnung somit eine dreifache Dichtung bildet, hat sie sich auf dem Markt bewährt. Die Dichtleiste weist jedoch eine aufwendige Form auf, da sie zwei- oder dreiteilig gestaltet ist, und zudem muss das Dichtungsprofil manuell an der Trägerprofilschiene befestigt werden.A generic door seal as sound insulation and as protection against drafts is known from EP-A-0'338'974. It consists essentially of a downwardly open, U-shaped guide profile rail, a sealing strip which can be displaced relative to the guide profile rail and a lowering mechanism for lowering or raising the sealing strip when the door is closed or opened. The lowering mechanism is described in DE-A-195'16'530. The sealing strip has a carrier profile rail and a one-piece, essentially U-shaped elastomeric sealing profile. When the door is closed, the sealing profile lies on the floor with a lower sealing lip. Furthermore, it is attached to the carrier profile rail on both sides, with legs that protrude beyond the attachment point and slide against the inner walls of the guide profile rail and form lateral sealing lips. Since this arrangement thus forms a triple seal, it has proven itself on the market. However, the sealing strip has an elaborate shape because it is designed in two or three parts, and also the sealing profile must be attached manually to the support rail.

JP 10 238251 offenbart ebenfalls eine absenkbare Türdichtung mit einer Führungsprofilschiene und einer darin verschiebbaren Dichtleiste. Die Dichtleiste ist an ihren oberen und unteren Enden mit elastischen Lippen versehen, wobei die oberen Lippen dichtend an der Innenseite der Führungsprofilschiene und die unteren Lippen am Boden anliegen sollen. Die oberen Lippen sind an der oberen Stirnfläche der Dichtleiste angeordnet, wobei sie nach unten gerichtet sind. Dies weist den Nachteil auf, dass sie leicht abbrechen können. Zudem ist ihre Anlagefläche relativ klein.JP 10 238251 also discloses a lowerable door seal with a guide profile rail and a sealing strip which can be moved therein. The sealing strip is provided with elastic lips at its upper and lower ends, the upper lips sealingly resting against the inside of the guide profile rail and the lower lips against the floor. The upper lips are arranged on the upper end face of the sealing strip, whereby they are directed downwards. This has the disadvantage that they can easily break off. In addition, their contact area is relatively small.

Des weiteren ist eine absenkbare Türdichtung mit einer einstückigen Dichtleiste bekannt. Ein oberer Teil bildet wiederum ein Trägerprofil, welches mit dem Absenkmechanismus in Verbindung bringbar ist und deshalb starr ausgebildet ist. Ein unterer Teil ist flexibel ausgestaltet und bildet eine untere Dichtlippe. Diese Türdichtung weist jedoch nur eine einfache Dichtung auf.Furthermore, a lowerable door seal with a one-piece sealing strip is known. An upper part in turn forms a support profile which can be connected to the lowering mechanism and is therefore rigid. A lower part is flexible and forms a lower sealing lip. However, this door seal has only a simple seal.

US-A-3'453'780 offenbart ferner eine Türdichtung, welche einen absenkbaren steifen Kern aufweist. Dieser Kern ist mit seitlichen Noppen versehen, welche jedoch nicht der Dichtung sondern der Führung des Kerns dienen.US-A-3'453'780 further discloses a door seal which has a lowerable rigid core. This core is provided with side knobs, which, however, do not serve to seal but to guide the core.

Darstellung der ErfindungPresentation of the invention

Es ist deshalb Aufgabe der Erfindung, eine absenkbare Türdichtung zu schaffen, welche einfach herstellbar ist, welche stabil ist und trotzdem eine dreifache Dichtung ermöglicht.It is therefore an object of the invention to provide a lowerable door seal which is easy to manufacture and which is stable is and still allows a triple seal.

Diese Aufgabe löst eine absenkbare Türdichtung mit den Merkmalen des Patentanspruches 1.This object is achieved by a lowerable door seal with the features of claim 1.

Die erfindungsgemässe Türdichtung weist eine Dichtleiste mit einer Trägerprofilschiene auf, an welcher seitlich Dichtlippen angeformt sind. Vorzugsweise sind die Dichtlippen dabei nach oben gerichtet oder es sind seitlich vorstehende Rippen.The door seal according to the invention has a sealing strip with a carrier profile rail, on which sealing lips are integrally formed on the side. In this case, the sealing lips are preferably directed upwards or there are ribs projecting to the side.

In einer bevorzugten Ausführungsform ist auch eine untere Dichtlippe angeformt.In a preferred embodiment, a lower sealing lip is also formed.

Vorteilhaft ist, dass die Dichtlippen, oder zumindest die seitlichen Dichtlippen, nicht an der Trägerprofilschiene befestigt werden müssen. Die Trägerprofilschiene kann somit eine einfache Form aufweisen. Sie muss über keine Befestigungselemente verfügen. Vorteilhaft ist ferner, dass sich die Türdichtung schmal gestalten lässt.It is advantageous that the sealing lips, or at least the lateral sealing lips, do not have to be attached to the carrier profile rail. The carrier profile rail can thus have a simple shape. It does not have to have any fasteners. It is also advantageous that the door seal can be made narrow.

In einer bevorzugten Ausführungsform sind am oberen Ende der Dichtleiste Schall-Dämpfungselemente vorhanden, damit die Dichtleiste beim Anheben möglichst leise an die Führungsprofilschiene anschlägt. In einem Ausführungsbeispiel sind an oberen Enden der Trägerprofilschiene Dämpfungselemente angeordnet, in einem anderen Ausführungsbeispiel überragen die seitlichen Dichtlippen die oberen Enden der Trägerprofilschiene und bilden selber die Dämpfungselemente.In a preferred embodiment, sound damping elements are provided at the upper end of the sealing strip so that the sealing strip strikes the guide profile rail as quietly as possible when it is lifted. In one embodiment, damping elements are arranged at the upper ends of the carrier profile rail; in another embodiment, the lateral sealing lips protrude above the upper ends of the carrier profile rail and form the damping elements themselves.

Weitere vorteilhafte Ausführungsformen gehen aus den abhängigen Patentansprüchen hervor.Further advantageous embodiments emerge from the dependent patent claims.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention

In Figur 1 ist eine erste Ausführungsform der erfindungsgemässen absenkbaren Türdichtung dargestellt. Sie besteht im wesentlichen aus einer nach unten offenen, u-förmigen Führungsprofilschiene 2, einer in dieser gelagerten, relativ zur Führungsprofilschiene 2 absenk- und anhebbare Dichtleiste 3 und einem nicht dargestellten, aber hinlänglich bekannten Absenkmechanismus zur Absenkung und Anhebung der Dichtleiste 3, welcher oberhalb der Dichtleiste 3 in der Führungsprofilschiene 2 angeordnet ist.1 shows a first embodiment of the lowerable door seal according to the invention. It essentially consists of a downwardly open, U-shaped guide rail 2, a sealing bar 3 mounted in it, which can be lowered and raised relative to the guide rail 2, and a lowering mechanism, not shown but well known, for lowering and raising the sealing bar 3, which is above the sealing strip 3 is arranged in the guide rail 2.

Die Führungsprofilschiene 2 ist vorzugsweise aus einem Metall, insbesondere Aluminium, gefertigt. Sie kann jedoch auch aus Kunststoff bestehen. Üblicherweise ist sie in einer in einer Unterkante der Türe 1 eingelassenen Nut 10 befestigt und erstreckt sich über die gesamte Länge der Türe. Sie kann aber auch mittels Winkelkonstruktionen an einem Türblatt befestigt sein. Weitere Befestigungsarten sind möglich.The guide rail 2 is preferably made of a metal, in particular aluminum. However, it can also come from Plastic. It is usually fastened in a groove 10 embedded in a lower edge of the door 1 and extends over the entire length of the door. But it can also be attached to a door leaf by means of angle constructions. Other types of fastening are possible.

Die Dichtleiste 3, welche dieselbe Länge aufweist wie die Führungsprofilschiene 2, besteht aus einer Trägerprofilschiene 30, einer unteren Dichtlippe 31 und mindestens zwei seitlichen Dichtlippen 32. Die Trägerprofilschiene 30 weist einen im wesentlichen u-förmigen, nach oben offenen Querschnitt auf, wobei sie zwei parallele, vertikale Schenkel 34 und mindestens einen diese verbindenden horizontalen Steg 35 aufweist. In der durch die Trägerprofilschiene 30 geformte Nut 4 ist der nicht dargestellte Absenkmechanismus angeordnet.The sealing strip 3, which has the same length as the guide profile rail 2, consists of a carrier profile rail 30, a lower sealing lip 31 and at least two lateral sealing lips 32. The carrier profile rail 30 has a substantially U-shaped cross section which is open at the top, whereby it has two has parallel, vertical legs 34 and at least one horizontal web 35 connecting them. The lowering mechanism, not shown, is arranged in the groove 4 formed by the carrier profile rail 30.

Die seitlichen Dichtlippen 32 oder Schenkel sind an Seitenflächen der Trägerprofilschiene 30, genauer an je einem der vertikalen Schenkel 34 angeformt, wobei sie gleitend an den Innenwänden 20 der Führungsprofilschiene 2 anliegen. In diesem Beispiel überragen sie die Schenkel 34 oben nicht, sondern sind vorzugsweise kürzer als diese. Die untere Dichtlippe 31 ist in einer einfachen Ausführungsform in bekannter Weise in an der Trägerprofilschiene 30 angeformten Befestigungselementen eingehängt. In einer bevorzugten, hier dargestellten Ausführungsform ist sie jedoch auch an die Trägerprofilschiene 30, genauer am untersten Steg 35, angeformt. Die Dichtleiste 3 ist somit durch ein einstückiges Element gebildet.The lateral sealing lips 32 or legs are formed on the side surfaces of the support rail 30, more precisely on one of each of the vertical legs 34, and they slide against the inner walls 20 of the guide rail 2. In this example, they do not protrude above the legs 34, but are preferably shorter than them. In a simple embodiment, the lower sealing lip 31 is suspended in a known manner in fastening elements molded onto the carrier profile rail 30. In a preferred embodiment shown here, however, it is also molded onto the carrier profile rail 30, more precisely at the lowest web 35. The sealing strip 3 is thus formed by a one-piece element.

Besteht die Trägerprofilschiene 30 aus Kunststoff, lassen sich die Dichtlippen 31, 32 coextrudieren. Dabei ist das Trägerprofil 30 starr und besteht somit aus einem härteren Kunststoff als die flexiblen, elastomeren Dichtlippen 31,32. Diese bestehen vorzugsweise aus Silikongummi. Besteht die Trägerprofilschiene 30 aus einem Metall, insbesondere Aluminium, so sind die Dichtlippen 31,32, welche vorzugsweise wiederum aus Silikongummi bestehen, angespritzt. Sind die Dichtlippen angespritzt, so weist die Trägerprofilschiene an den Anspritzstellen vorzugsweise hier nicht dargestellte Vertiefungen oder Rillen als Ansatzhilfen für die Dichtlippen auf.If the carrier profile rail 30 is made of plastic, the sealing lips 31, 32 can be coextruded. The carrier profile 30 is rigid and thus consists of a harder plastic than the flexible, elastomeric sealing lips 31, 32. These exist preferably made of silicone rubber. If the carrier profile rail 30 consists of a metal, in particular aluminum, then the sealing lips 31, 32, which in turn are preferably made of silicone rubber, are injection molded. If the sealing lips are injection molded, the carrier profile rail preferably has depressions or grooves (not shown here) at the injection points as attachment aids for the sealing lips.

Die untere Dichtlippe 31 weist einen u-förmigen Querschnitt auf und liegt im geschlossenen Zustand der Türe am Boden B an. Die seitlichen Dichtlippen 32 liegen an Innenwänden 20 der Führungsprofilschiene 2 an. Vorzugsweise weisen sie, wie dargestellt, einen Winkel auf, wobei ein erster Schenkel 32' in einem spitzen Winkel mit der Trägerprofilschiene 30 verbunden ist, so dass er nach oben ragt. Der spitze Winkel beträgt mindestens annähernd 15°. Ein zweiter, freier Schenkel 32" verläuft mindestens annähernd parallel zu einer der Innenwände 20 der Führungsprofilschiene 2.The lower sealing lip 31 has a U-shaped cross section and is in contact with the floor B when the door is closed. The lateral sealing lips 32 rest on inner walls 20 of the guide rail 2. As shown, they preferably have an angle, a first leg 32 ′ being connected at an acute angle to the carrier profile rail 30, so that it projects upwards. The acute angle is at least approximately 15 °. A second, free leg 32 ″ runs at least approximately parallel to one of the inner walls 20 of the guide profile rail 2.

In dem in Figur 1 dargestellten Ausführungsbeispiel weisen die Schenkel 34 der Trägerprofilschiene 30 obere Enden auf, welche mit einem Dämpfungselement 33 versehen sind, um den beim Anschlagen in der oberen Position entstehenden Ton zu dämpfen. Das Dämpfungselement ist eine Kunststoffkuppe, welche ebenfalls koextrudiert oder angespritzt ist. Vorzugsweise besteht sie aus PVC, Silikongummi oder einem anderen geeigneten schalldämmenden Material.In the exemplary embodiment shown in FIG. 1, the legs 34 of the carrier profile rail 30 have upper ends which are provided with a damping element 33 in order to dampen the sound produced when struck in the upper position. The damping element is a plastic cap, which is also co-extruded or molded. It is preferably made of PVC, silicone rubber or another suitable sound-absorbing material.

In der in Figur 2 dargestellten Ausführungsform überragen die seitlichen Dichtlippen 32 die oberen Enden der Schenkel 34 und bilden mit ihren eigenen oberen Enden die Dämpfungselemente 33, welche in ihrer oberen Position ebenfalls an der Unterseite eines oberen Steges 21 der Führungsprofilschiene 2, an oberen, vorstehenden Nasen 22 der Führungsprofilschiene oder an anderen Elementen des Trägerprofils auftreffen.In the embodiment shown in FIG. 2, the lateral sealing lips 32 protrude the upper ends of the legs 34 and, with their own upper ends, form the damping elements 33, which in their upper position are also on the underside of an upper web 21 of the guide profile rail 2, on upper, projecting lugs 22 of the guide rail or other elements of the support profile.

Figur 3 zeigt eine weitere Ausführungsform, in welcher mehrere seitliche Dichtlippen 32 in Form von vorstehenden Rippen oder Noppen vorhanden sind. In einer Variante sind sie elastisch ausgebildet, sie können aber auch relativ starr ausgebildet sein. Im hier dargestellten Fall weisen sie einen halbkreisförmigen Querschnitt auf und erstrecken sich gleichabständig oder mit unregelmässigen Abständen über die gesamte Länge der vertikalen Schenkel 34. Diese Ausführungsform ermöglicht eine sehr schmale Gestaltung der Türdichtung.FIG. 3 shows a further embodiment in which a plurality of lateral sealing lips 32 are provided in the form of protruding ribs or knobs. In one variant, they are designed to be elastic, but they can also be designed to be relatively rigid. In the case shown here, they have a semicircular cross section and extend at the same distance or at irregular intervals over the entire length of the vertical legs 34. This embodiment enables the door seal to be designed very narrowly.

Im Ausführungsbeispiel gemäss Figur 4 sind die seitlichen Dichtlippen 32 als Folien ausgebildet, wobei je ein Folienblatt auf einer Seite der Trägerprofilschiene angeformt ist. Das Folienblatt ragt dabei schräg nach oben. In diesem Fall lassen sich die Dichtlippen aus demselben Material fertigen wie die Trägerprofilschiene, wobei sie durch ihre Dünnwandigkeit flexibel genug sind, um eine Dichtung zu gewährleisten und gleitend an der Innenseite der Führungsprofilschiene anzuliegen. Ferner ist die untere Dichtlippe durch zwei nach unten ragende Lamellen 31' gebildet, welche je an einem Ende am untersten Steg 35 der Führungsprofilschiene 30 angeformt sind und ihr anderes Ende frei ist und im abgesenkten Zustand der Dichtung auf dem Boden B aufliegt. Diese Art der unteren Dichtlippe lässt sich auch mit den in den anderen Figuren dargestellten Ausführungsformen anstelle der u-förmigen Dichtlippe kombinieren.In the exemplary embodiment according to FIG. 4, the lateral sealing lips 32 are designed as foils, one foil sheet each being formed on one side of the carrier profile rail. The foil sheet protrudes diagonally upwards. In this case, the sealing lips can be made from the same material as the carrier profile rail, and their thin walls make them flexible enough to ensure a seal and to slide against the inside of the guide profile rail. Furthermore, the lower sealing lip is formed by two downwardly projecting lamellae 31 ', which are each formed at one end on the lowest web 35 of the guide rail 30 and their other end is free and rests on the bottom B in the lowered state of the seal. This type of lower sealing lip can also be combined with the embodiments shown in the other figures instead of the U-shaped sealing lip.

Figur 5 zeigt ein Ausführungsbeispiel, bei welchem je eine seitliche Dichtlippe und je eine Lamelle der unteren Dichtlippe als einstückige Dichtlippe 36 ausgebildet ist, wobei die einstückigen Dichtlippen 36 auf je einer Seite der Trägerprofilschiene in deren unteren Kantenbereich angeformt sind. Diese Ausführungsform weist den Vorteil auf, dass sie einfach herstellbar ist, da lediglich an zwei Stellen Dichtlippen koextrudiert beziehungsweise angespritzt werden müssen. In einer hier nicht dargestellten Ausführungsform ist die Dichtlippe einstückig hergestellt. Das heisst, die unseren Dichtlippen sind über einen Steg miteinander verbunden.FIG. 5 shows an exemplary embodiment in which a lateral sealing lip and a lamella of the lower sealing lip are each formed as a one-piece sealing lip 36, the one-piece sealing lips 36 are formed on one side of the support rail in the lower edge region. This embodiment has the advantage that it is easy to produce, since sealing lips only have to be coextruded or injection molded at two points. In an embodiment not shown here, the sealing lip is made in one piece. This means that our sealing lips are connected to each other via a web.

Die erfindungsgemässe Absenkdichtung ist einfach herstellbar, kostengünstig und relativ schmal, ermöglicht jedoch trotzdem eine dreifache Dichtung.The lowering seal according to the invention is simple to produce, inexpensive and relatively narrow, but nevertheless enables a triple seal.
