Description

Technisches Gebiet der ErfindungTechnical field of the invention

Die Erfindung betrifft eine Türdichtung für eine schwellenlose Tür gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a door seal for a threshold-free door according to the preamble of patent claim 1.

Stand der TechnikState of the art

Absenkbare Türdichtungen werden als Schallschutz und als Schutz gegen Zugluft eingesetzt. Üblicherweise bestehen sie aus einer nach unten offenen Führungsschiene uförmigen Querschnitts, einer in der Führungsschiene gehaltenen und relativ zu dieser verschiebbaren ein- oder mehrstückigen Dichtleiste und einem Antriebsmechanismus zum selbsttätigen Absenken und Anheben der Dichtleiste, wobei der Antriebsmechanismus durch die Schliessung bzw. Öffnung der Türe aktiviert wird.Lowerable door seals are used as sound insulation and as protection against drafts. Typically, they consist of a downwardly open guide rail U-shaped cross-section, held in the guide rail and relative to this sliding single or multi-piece sealing strip and a drive mechanism for automatically lowering and raising the sealing strip, the drive mechanism activated by the closing or opening of the door becomes.

Aus EP-A-0 338 974 , EP 1 489 257 und US 2004/0111972 sind Dichtungen bekannt, welche sowohl seitlich wie auch nach unten dichten. Die Dichtleiste ist hierfür einstückig ausgebildet und weist nach oben ragende Schenkel auf, welche an den inneren Seitenwänden der Führungsschiene mindestens teilweise dichtend anliegen. Unterhalb ihrer Befestigungsstelle an der Trägerschiene geht die Dichtleiste in einen bogenförmigen Steg über, welcher im abgesenkten Zustand auf den Fussboden gepresst wird, sich entsprechend deformiert und die untere Dichtfunktion übernimmt.Out EP-A-0 338 974 . EP 1 489 257 and US 2004/0111972 seals are known which seal both laterally and downwardly. The sealing strip is for this purpose formed in one piece and has upwardly projecting legs, which bear against the inner side walls of the guide rail at least partially sealing. Below its attachment point to the support rail, the sealing strip goes into an arcuate web, which is pressed in the lowered state on the floor, deformed accordingly and assumes the lower sealing function.

EP-A-1 162 341 offenbart ebenfalls eine Dichtung mit seitlichen Schenkeln und einem auf dem Boden aufliegenden bogenförmigen Steg, wobei die Schenkel ausserhalb der Führungsschiene verlaufen. Auf beiden Seiten des Stegs sind nach unten schräg nach aussen ragende Stützschenkel angeordnet, welche die Schenkel im abgesenkten Zustand an die Führungsschiene pressen sollen. EP-A-1 162 341 also discloses a seal with side legs and resting on the floor arcuate web, wherein the legs extend outside the guide rail. On both sides of the web obliquely outwardly projecting support legs are arranged, which the legs in the lowered state to press against the guide rail.

Bei der aus der DE-U-298 16 448 bekannten Türdichtung werden durch zwei am Dichtbogen beidseits symmetrisch zur Mittelachse angeordnete Dichtlippen zusätzliche Auflagekanten auf dem Boden geschaffen. Dafür fehlt jedoch eine ausreichende seitliche Dichtung.At the time of the DE-U-298 16 448 known door seal are created by two sealing lips on both sides symmetrically to the central axis arranged sealing lips additional support edges on the floor. For this, however, a sufficient lateral seal is missing.

EP-A-0 046 441 weist zwei senkrecht nach unten ragende Dichtlippen auf. Auch hier fehlt eine seitliche Dichtung. EP-A-0 046 441 has two vertically downwardly projecting sealing lips. Again, a lateral seal is missing.

Obwohl diese Dichtungen bei Qualitätsbauten eine absolut zufrieden stellende Dichtfunktion ausüben, so sind sie bei schwierigen Bauten doch oft unzulänglich. Bei kostengünstigen Neubauten werden die Böden oft derart gegossen, dass sie bis zu 1 cm Höhendifferenz aufweisen. Insbesondere Altbauten weisen oft wellige, symmetrisch oder asymmetrisch bucklige, hohle, oder schräge Böden auf, so dass die Türdichtung nicht über die gesamte Länge auf dem Boden aufliegen und genügend dichten kann. Auch Fugen von Parkettböden oder Plattenböden können zu einer ungenügenden Dichtleistung führen.Although these gaskets have an absolutely satisfactory sealing function in quality constructions, they are often inadequate in difficult constructions. In low-cost new buildings, the soils are often poured so that they have up to 1 cm height difference. In particular, old buildings often have wavy, symmetrical or asymmetrical humped, hollow or sloping floors, so that the door seal can not rest on the floor over the entire length and can seal sufficiently. Even joints of parquet floors or slabs can lead to insufficient sealing performance.

DE 297 20 8543 U offenbart ferner eine Absenkdichtung, welche schräg zur Horizontalen abgesenkt wird. Diese Dichtung weist drei nach unten ragende Zungen auf, deren längste Zunge zur Anlage an die Türzarge dienen soll. DE 297 20 8543 U further discloses a lowering seal, which is lowered obliquely to the horizontal. This seal has three downwardly projecting tongues whose longest tongue is intended to bear against the door frame.

EP 0 810 345 zeigt ein Torblatt-Dichtungsprofil mit einer schräg nach unten ragenden Dichtlippe. Es soll bei grösseren Bodenunebenheiten einen sicheren bodenseitigen Abschluss ermöglichen. EP 0 810 345 shows a door leaf sealing profile with an obliquely downwardly projecting sealing lip. It is to allow for larger uneven ground a secure bottom-side conclusion.

Darstellung der ErfindungPresentation of the invention

Es ist deshalb eine Aufgabe der Erfindung, eine absenkbare Türdichtung der eingangs genannten Art für stark unebene Böden zu schaffen, die neben einer hohen Flexibilität und guten Dichtung gegen die Bodenunterlage auch eine gute seitliche Dichtung aufweist und konstruktiv einfach aufgebaut ist.It is therefore an object of the invention to provide a lowerable door seal of the type mentioned for heavily uneven floors, in addition to a high degree of flexibility and good seal against the floor pad and a good lateral seal has and is structurally simple.

Diese Aufgabe löst eine Türdichtung mit den Merkmalen das Patentanspruchs 1.This object is achieved by a door seal having the features of patent claim 1.

Die erfindungsgemässe Türdichtung weist eine Führungsschiene und eine in der Führungsschiene absenkbar und anhebbar gehaltene Trägerschiene mit einem darin gehaltenen Dichtelement auf, welches im abgesenkten Zustand dichtend auf einem Boden anliegt und eine untere Dichtung bildet. Das Dichtelement verfügt über einen im wesentlichen u-förmigen Querschnitt mit zwei Schenkeln und einen Steg, welcher untere Enden der zwei Schenkel miteinander verbindet, wobei mindestens einer der zwei Schenkel eine seitliche Dichtung bildet. Erfindungsgemäss ist am Steg mindestens eine nach unten ragende Dichtlippe angeformt, welche im abgesenkten Zustand dichtend auf dem Boden anliegt und in Absenkrichtung so lang bemessen ist, dass sich der Steg in diesem abgesenkten Zustand beabstandet zum Boden befindet.The door seal according to the invention has a guide rail and a support rail which can be lowered and raised in the guide rail and has a sealing element held therein, which in the lowered state seals on one side Ground abuts and forms a lower seal. The sealing element has a substantially U-shaped cross section with two legs and a web which connects lower ends of the two legs with each other, wherein at least one of the two legs forms a lateral seal. According to the invention at least one downwardly projecting sealing lip is formed on the web, which rests sealingly in the lowered state on the ground and is measured in the lowering so long that the web is spaced in this lowered state to the ground.

Vorzugsweise ist der Steg relativ kurz bemessen, so dass er im abgesenkten Zustand kaum verformt wird. Des weiteren ist der Übergang zwischen Steg und seitlichen Schenkeln vorzugsweise geknickt bzw. verdünnt ausgebildet.Preferably, the web is relatively short, so that it is hardly deformed in the lowered state. Furthermore, the transition between web and side legs is preferably formed kinked or thinned.

Vorzugsweise werden die Trägerschiene und das Dichtelement ausschliesslich in vertikaler Richtung abgesenkt und angehoben und haben keinen horizontalen Bewegungsanteil.Preferably, the carrier rail and the sealing element are lowered and raised exclusively in the vertical direction and have no horizontal movement component.

Die erfindungsgemässe Türdichtung eignet sich insbesondere für stark unebene und schiefe Böden, wie sie etwa bei Renovationen oder kostengünstigen Neubauten auftreten.The inventive door seal is particularly suitable for very uneven and inclined floors, as they occur for example in renovations or low-cost new buildings.

Weitere vorteilhafte Ausführungsformen gehen aus den abhängigen Patentansprüchen hervor.Further advantageous embodiments will become apparent from the dependent claims.

Beschreibung von bevorzugten AusführungsbeispielenDescription of preferred embodiments

Die Figuren 1 bis 3 zeigen ein Ausführungsbeispiel einer erfindungsgemässen absenkbaren Türdichtung. Sie weist eine Führungsschiene 1, eine darin anhebbar und absenkbar gehaltene Trägerschiene 2 und ein an der Trägerschiene 2 angeordnetes Dichtelement 4 auf. Ferner ist ein Absenkmechanismus vorhanden, um die Türdichtung durch Öffnen bzw. Schliessen der Türe automatisch anzuheben bzw. abzusenken. Ein Beispiel eines derartigen Absenkmechanismus ist in DE 195 16 530 beschrieben. Andere Arten derartiger Mechanismen sind jedoch auch einsetzbar.The FIGS. 1 to 3 show an embodiment of an inventive lowerable door seal. It has a guide rail 1, a support rail 2 which can be lifted and lowered therein, and a sealing element 4 arranged on the support rail 2. Furthermore, a lowering mechanism is provided to automatically raise or lower the door seal by opening or closing the door. An example of such a lowering mechanism is shown in FIG DE 195 16 530 described. However, other types of such mechanisms can also be used.

Die Führungsschiene 1 ist vorzugsweise eine Profilschiene, welche durch Strangpressen aus Aluminium gefertigt ist. Sie weist einen u-förmigen Querschnitt auf, mit einem oberen Steg 10 und zwei parallelen, vom oberen Steg 10 rechtwinklig abragenden äusseren Seitenwänden 11, 12. Benachbart zum oberen Steg 10 und annähernd parallel zu diesem ragen von den Seitenwänden 11, 12 gegeneinander gerichtete Führungsstege 13, 14 unter Bildung einer hinterschnittenen Längsnut 15 nach innen ab. Die Längsnut 15 dient zur Aufnahme des Führungsstabes des Absenkmechanismus, welcher vorzugsweise mehrere Blattfedern umfasst.The guide rail 1 is preferably a profile rail, which is made by extrusion of aluminum. It has a U-shaped cross-section, with an upper web 10 and two parallel, from the upper web 10 at right angles projecting outer side walls 11, 12. Adjacent to the upper web 10 and approximately parallel to this protrude from the side walls 11, 12 against each other directed guide webs 13, 14 to form an undercut longitudinal groove 15 inwardly. The longitudinal groove 15 serves to receive the guide rod of the lowering mechanism, which preferably comprises a plurality of leaf springs.

Innerhalb der Führungsschiene 1 ist eine Trägerschiene 2 zur Befestigung eines Dichtelements 4 angeordnet. Die Trägerschiene 2, die beispielsweise ebenfalls ein stranggepresstes Aluminiumprofil sein kann, umfasst ein Profilteil mit im wesentlichen U-förmigem Querschnitt, mit einem oberen Bügel 22 und von diesem rechtwinklig abragenden parallelen innere Seitenwände 20, 21, deren freie Enden gegen den oberen Steg 10 der Führungsschiene 1 weisen und einen Aufnahmeraum für ein Dämpfungselement 3 begrenzen. An der dem querschnittlich U-förmigen Profilteil der Trägerschiene 2 abgewandten Seite des oberen Bügels 22 ragt mittig und parallel zu den beiden inneren Seitenwänden 20, 21 ein Kamm 24 ab. Der Kamm 24 ist an seinem dem oberen Bügel 22 entfernt liegenden Ende von einem im wesentlichen parallel zum oberen Bügel 22 angeordneten Endsteg oder unteren Bügel 23 begrenzt.Within the guide rail 1, a support rail 2 for fixing a sealing element 4 is arranged. The support rail 2, which may for example also be an extruded aluminum profile, comprises a profile part with a substantially U-shaped cross-section, with an upper bracket 22 and from this at right angles protruding parallel inner side walls 20, 21, the free ends facing the upper web 10 of the guide rail 1 and define a receiving space for a damping element 3. At the side facing away from the cross-sectionally U-shaped profile part of the support rail 2 side of the upper bracket 22 protrudes centrally and parallel to the two inner side walls 20, 21 from a comb 24. The comb 24 is bounded at its end remote from the upper bracket 22 by an end web or lower bracket 23 arranged substantially parallel to the upper bracket 22.

Die über den oberen Bügel 22 der Trägerschiene 2 hinaus bis zum unteren Bügel 23 hin verlängerten inneren Seitenwände 20, 21 sind zwischen oberem Bügel 22 und unterem Bügel 23 unter Bildung von zwei längslaufenden Öffnungsschlitzen von zwei symmetrisch zu einander angeordneten, von oberen Bügel 22, Kamm 24 und unterem Bügel 23 begrenzten, hinterschnittenen Längsnuten 25, 26 unterbrochen.The over the upper bracket 22 of the support rail 2 also extended to the lower bracket 23 toward inner side walls 20, 21 are arranged between upper bracket 22 and lower bracket 23 to form two longitudinal opening slots of two symmetrically to each other, of upper bracket 22, comb 24 and lower bracket 23 limited, undercut longitudinal grooves 25, 26 interrupted.

Die über den oberen Bügel 22 hinaus verlängerten Seitenwände 20, 21 sind im Bereich des oberen Bügels 22 leicht nach innen abgewinkelt und laufen gegen den unteren Bügel 23 hin auf einander zu. Der untere Bügel 23 ist symmetrisch zum Kamm 24 und vom oberen Bügel 22 weglaufend leicht nach aussen abgewinkelt.The extended beyond the upper bracket 22 side walls 20, 21 are slightly angled in the region of the upper bracket 22 inward and run against the lower bracket 23 toward each other. The lower bracket 23 is symmetrical to the comb 24 and away from the upper bracket 22 running away slightly angled outwards.

Das Dichtelement 4 ist als querschnittlich U-förmiges Profil aus beispielsweise Silikongummi mit von einem Steg 43 abragenden Schenkeln 40, 41 ausgestaltet. Hierbei überspannt der Steg 43 den schwach gewinkelten unteren Bügel 23 unter Bildung eines Längsspaltes 5 mit einem schmalen linsenförmigem Öffnungsquerschnitt. Der Steg 43 kann auch mindestens teilweise am unteren Bügel 23 anliegen. Vorzugsweise ist der Steg 43 annähernd gleich lang ausgebildet wie die Länge des untersten Bereichs der Trägerschiene 2, hier also des unteren Bügels 23.The sealing element 4 is configured as a cross-sectionally U-shaped profile of, for example, silicone rubber with legs 40, 41 projecting from a web 43. Here, the web 43 spans the slightly angled lower bracket 23 to form a longitudinal gap 5 with a narrow linsenförmigem opening cross-section. The web 43 may also rest at least partially on the lower bracket 23. Preferably, the web 43 is formed approximately the same length as the length of the lowermost portion of the support rail 2, here so the lower bracket 23rd

Die beiden Schenkel 40, 41 des Dichtelements 4 weisen mit ihren freien Enden gegen den oberen Steg 43 der Führungsschiene 1 hin und sind zwischen den äusseren Seitenwänden 11, 12 der Führungsschiene 1 und den inneren Seitenwänden 20, 21 der Trägerschiene 2 angeordnet. Die zwei Schenkel 40, 41 können mit ihren oberen Enden auch an der Trägerschiene befestigt sein. Die Schenkel 40, 41 können von der Trägerschiene 2 weg gegen die Seitenwände 11, 12 der Führungsschiene 1 hin abstehen oder sie können an den Seitenwänden 20, 21 der Trägerschiene 2 anliegen. Des weiteren können sie mit Noppen oder anderen Erhebungen versehen bzw. mit glatter Oberfläche ausgebildet sein. Die Schenkel können auch ausserhalb der Führungsschiene hochgezogen sein, wie dies in EP 1 162 341 der Fall ist. Wesentlich ist jedoch, dass mindestens einer, vorzugsweise beide dieser zwei Schenkel im abgesenkten Zustand eine seitliche Dichtung bildet. Diese Dichtung kann zwischen Seitenwand der Trägerschiene 2 und Seitenwand der Führungsschiene 1 erfolgen oder zwischen Führungsschiene und Nut der Türe.The two legs 40, 41 of the sealing element 4 point with their free ends against the upper web 43 of the guide rail 1 and are arranged between the outer side walls 11, 12 of the guide rail 1 and the inner side walls 20, 21 of the support rail 2. The two legs 40, 41 may also be fastened with their upper ends to the carrier rail. The legs 40, 41 can from the Support rail 2 protrude away against the side walls 11, 12 of the guide rail 1 out or they can rest against the side walls 20, 21 of the support rail 2. Furthermore, they can be provided with nubs or other elevations or be formed with a smooth surface. The legs can also be pulled up outside the guide rail, as in EP 1 162 341 the case is. It is essential, however, that at least one, preferably both of these two legs in the lowered state forms a lateral seal. This seal can be made between the side wall of the support rail 2 and the side wall of the guide rail 1 or between the guide rail and the groove of the door.

Im Bereich des oberen Stegs 43 ragen zwei gegeneinander weisende innenseitig Anformungen 42, hier in Form von hinterschnittenen Federelementen von den Schenkeln 40, 41 des Dichtelements 4 nach innen ab und ragen in die hinterschnittenen Längsnuten 25, 26 ein. Das Dichtelement 4 ist so über hinterschnittene Nut-/FederVerbindungen an der Trägerschiene 2 befestigt.In the region of the upper web 43, two mutually facing inner projections 42 protrude inwardly from the legs 40, 41 of the sealing element 4 in the form of undercut spring elements and protrude into the undercut longitudinal grooves 25, 26. The sealing element 4 is secured to the support rail 2 via undercut tongue and groove connections.

Im Bereich des Übergangs der Schenkel 40, 41 des Dichtelements 4 in den Steg 43 sind innenseitig längslaufende Kerbnuten 44 angeordnet.In the region of the transition of the legs 40, 41 of the sealing element 4 in the web 43 longitudinally extending notched grooves 44 are arranged inside.

Einer der Schenkel 40, 41 des Dichtelements 4, im vorliegenden Fall des ersten Schenkels 40, setzt sich im Bereich seines Übergangs zum Steg 43 als längslaufende Schräglippe 45 mit vorzugsweise gerundetem freien Ende fort. Die Dicht- oder Schräglippe 45 ist gegenüber dem ersten Schenkel 40 vorzugsweise um einen Winkel α von etwa 45° Grad nach innen gerichtet. Die Schräglippe weist vorzugsweise eine Länge von 5 bis 15 mm. Der spitze Winkel α zwischen der Absenkrichtung und der Dichtlippe 45 ist vorzugsweise 30° bis 70°, insbesondere 35° bis 60°.One of the legs 40, 41 of the sealing element 4, in the present case of the first leg 40, continues in the region of its transition to the web 43 as a longitudinal tapered lip 45 with a preferably rounded free end. The sealing or oblique rib 45 is preferably directed inwards relative to the first leg 40 by an angle α of approximately 45 °. The oblique lip preferably has a length of 5 to 15 mm. The acute angle α between the lowering direction and the sealing lip 45 is preferably 30 ° to 70 °, in particular 35 ° to 60 °.

Die Figuren 2 und 3 zeigen die Türdichtung in zwei unterschiedlichen Betriebszuständen. Bei geöffneter Tür befindet sich die Trägerschiene 2 innerhalb der Führungsschiene 1 (Fig. 2). Wird die Tür geschlossen, so wird die Trägerschiene 2 über einen eingebauten Absenkmechanismus innerhalb der Führungsschiene 1 selbsttätig abgesenkt. Figur 3 zeigt die in einer Längsnut von der Unterkante einer Tür T eingebaute Türdichtung, deren Schräglippe 45 mit ihrem freien Ende bei geschlossener Tür T einem Fussboden B anliegt. Selbstverständlich kann die Schräglippe 45 auch stärker auf dem Boden B angepresst werden, so dass sie nicht nur punktuell sondern über eine grössere Fläche aufliegt. Wesentlich ist jedoch, dass der Steg 43 in diesem Zustand den Boden nach wie vor nicht berührt und dass somit die Länge der Dichtung ausreicht bzw. der Hub so bemessen ist, dass die Dichtlippe die untere Dichtfunktion vorzugsweise ausschliesslich übernimmt.The FIGS. 2 and 3 show the door seal in two different operating conditions. When the door is open, the support rail 2 is within the guide rail 1 ( Fig. 2 ). If the door is closed, the support rail 2 is lowered automatically by means of a built-in lowering mechanism within the guide rail 1. FIG. 3 shows the in a longitudinal groove of the lower edge of a door T built-in door seal whose oblique lip 45 rests with its free end with the door closed T a floor B. Of course, the oblique lip 45 can also be pressed more strongly on the bottom B, so that it rests not only punctiform but over a larger area. It is essential, however, that the web 43 still does not touch the ground in this state and that thus the length of the seal is sufficient or the stroke is dimensioned such that the sealing lip preferably assumes the lower sealing function exclusively.

In Figur 4 ist eine absenkbare Türdichtung dargestellt. Die Dichtung ist im wesentlichen gleich ausgebildet. Anstelle der Schräglippe sind nun jedoch drei Vertikallippen 46 am Steg 43 angeordnet, welche beabstandet zueinander annähernd senkrecht nach unten ragen. Vorzugsweise sind alle Vertikallippen gleich lang. Auch hier liegen die Vertikallippen bzw. Rippen 46 im abgesenkten Zustand auf dem Boden auf, nicht jedoch der Steg 43. Es können ein, zwei, drei oder mehr Rippen vorhanden sein. Die Länge der Rippen beträgt vorzugsweise 5 bis 15 mm.In FIG. 4 a lowered door seal is shown. The seal is formed substantially the same. Instead of the oblique lip but now three vertical ribs 46 are arranged on the web 43, which spaced from each other approximately vertically projecting downwards. Preferably, all vertical lips are the same length. Again, the vertical ribs or ribs 46 are in the lowered state on the ground, but not the web 43. There may be one, two, three or more ribs. The length of the ribs is preferably 5 to 15 mm.

In Figur 4 ist eine Befestigungsart dargestellt. Es handelt sich um einen Befestigungswinkel 6.In FIG. 4 is a fastening shown. It is a mounting bracket. 6

Die hier beschriebenen Dichtelemente bzw. Dichtleisten sind vorzugsweise einstückig ausgebildet, wobei die Materialdicke der Schenkel, des Stegs und der Schräg- bzw. Vertikallippe vorzugsweise gleich ist.The sealing elements or sealing strips described here are preferably formed in one piece, wherein the material thickness of the legs, the web and the oblique or vertical lip is preferably the same.

Die erfindungsgemässe absenkbare Dichtung ist insbesondere zur Verwendung bei unebenen und schiefen Böden geeignet.The inventive lowerable seal is particularly suitable for use on uneven and sloping soils.
