Description

Die vorliegende Erfindung betrifft eine Dichtungsanordnung für eine Schiebetür umfassend eine über einen Mechanismus absenkbare Bodendichtung,

  • wobei der Mechanismus einen stirnseitig am Türblatt vorstehenden Auslöser umfasst, der beim Schließen der Schiebetür eingedrückt wird gegen eine den Auslöser beaufschlagende Federkraft des Absenkmechanismus,

The present invention relates to a sealing arrangement for a sliding door comprising a bottom seal which can be lowered by a mechanism,
  • wherein the mechanism comprises a shutter projecting on the front side of the door leaf, which is pressed when closing the sliding door against a spring force acting on the Absenkmechanismus the Absenkmechanismus,

Die DE 35 26 720 A1 beschreibt eine Dichtungsanordnung für eine Schiebetür der eingangs genannten Gattung, bei der der Schließmechanismus ein Kupplungselement umfasst, welches etwa eine Zapfenform aufweist, mit einem Widerlager, einer halsförmigen Verjüngung und einem Kopf. Dieses Kupplungselement wird aufgenommen von einer Bohrung im endseitigen Bereich der Schiebetür, wobei über zwei radial verlagerbare Kugeln eine zugfeste Verbindung zwischen dem Kupplungselement und der Schiebetür herstellbar ist. Dabei handelt es sich also um eine mechanische Verbindung ähnlich einer Rastverbindung, die durch eine entsprechende Zugkraft beim Öffnen der Schiebetür wieder gelöst wird.The DE 35 26 720 A1 describes a seal assembly for a sliding door of the type mentioned, in which the closing mechanism comprises a coupling element which has approximately a pin shape, with an abutment, a neck-shaped taper and a head. This coupling element is received by a bore in the end region of the sliding door, wherein a tensile connection between the coupling element and the sliding door can be produced via two radially displaceable balls. It is thus a mechanical connection similar to a locking connection, which is released by a corresponding tensile force when opening the sliding door again.

Bei einer Schiebetür mit einer absenkbaren Bodendichtung ist ein Schließmechanismus erforderlich, da der Auslöser federbelastet ist und dadurch bei zugeschobener Schiebetür der Auslöser versucht sich zu entspannen, das heißt, sich von dem Rahmenbauteil, gegen das die Schiebetür geschoben wird, wegzudrücken, wodurch eine Öffnungstendenz der Schiebetür entsteht. Je breiter die Schiebetür ist, umso größer muss die aufzuwendende Kraft sein, um über die Länge der Schiebetür die Bodendichtung in ihre Schließstellung abzusenken. Dementsprechend nimmt die Öffnungstendenz der Schiebetür durch den federbelasteten Auslöser mit zunehmender Breite der Schiebetür zu. Um ein selbsttätiges sich Öffnen der Schiebetür zu vermeiden, hat man daher bei herkömmlichen Schiebetüren in der Regel einen Verriegelungsmechanismus verwendet, der die Schiebetür in der geschlossenen Stellung festhält, was aber den Nachteil hat, dass dann zum Öffnen der Schiebetür zunächst eine manuelle Entriegelung vorgenommen werden muss. Dies bedeutet eine einfache Seitwärts-Schiebebewegung reicht beim Öffnen der Schiebetür nicht aus. Durch ein solches Erfordernis des Entriegelns wird der Bedienungskomfort bei der Betätigung der Schiebetür verringert.In a sliding door with a lowerable bottom seal, a locking mechanism is required because the trigger is spring loaded and thereby pushed sliding door of the trigger tries to relax, that is, from the frame member, against the sliding door is pushed to push away, creating an opening tendency of the sliding door. The wider the sliding door is, the greater the force that has to be expended in order to lower the floor seal into its closed position over the length of the sliding door. Accordingly, the opening tendency of the sliding door by the spring-loaded trigger increases with increasing width of the sliding door. In order to avoid an automatic opening of the sliding door, it has therefore been used in conventional sliding doors usually a locking mechanism that holds the sliding door in the closed position, but this has the disadvantage that then to open the sliding door first a manual unlocking be made got to. This means a simple sideways sliding movement is not enough when opening the sliding door. Such a requirement of unlocking reduces the ease of operation of operating the sliding door.

Bei der aus der eingangs erwähnten DE 35 26 720 bekannten Dichtungsanordnung für eine Schiebetür ist nachteilig, dass es einer sehr genauen Führung der Schiebetür bedarf, damit der Zapfen exakt in die entsprechende Aufnahme der Schiebetür trifft. Eine derart exakte Führung für eine Schiebtür lässt sich aber in der Praxis nur mit sehr hohem Aufwand realisieren, weshalb sich die aus dem Stand der Technik bekannte Lösung nicht in wirtschaftlich sinnvoller Weise umsetzen lässt.When from the above-mentioned DE 35 26 720 known sealing arrangement for a sliding door is disadvantageous that it requires a very accurate guidance of the sliding door so that the pin meets exactly in the corresponding recording of the sliding door. Such an exact guide for a sliding door can be realized in practice only with great effort, which is why the known from the prior art solution can not be implemented in an economically meaningful way.

Ein Problem lag somit darin eine Dichtungsanordnung für eine Schiebetür der eingangs genannten Gattung zur Verfügung zu stellen, bei der der Schließmechanismus der der Öffnungstendenz durch den federbelasteten Auslöser entgegenwirkt so ausgebildet ist, dass sich die Schiebetür dennoch bequem und einfach öffnen lässt.A problem was thus to provide a sealing arrangement for a sliding door of the type mentioned above, in which the closing mechanism counteracts the opening tendency by the spring-loaded release is designed so that the sliding door can still be opened conveniently and easily.

Aus der Europäischen Patentanmeldung mit der Veröffentlichungsnummer EP 0 354 505 A2 ist eine Schiebewand mit Ganzglas-Schiebeflügel bekannt, die eine über einen Mechanismus absenkbare Bodendichtung aufweisen. Der Mechanismus umfasst einen stirnseitig am Ganzglas-Schiebeflügel vorstehenden Auslöser, der beim Schließen der Schiebetür gegen eine den Auslöser beaufschlagende Federkraft des Absenkmechanismus eingedrückt wird. Die Ganzglas-Schiebeflügel weisen ein Schließmechanismus mit einer Magnetleiste auf, um u. a. der durch den federbelasteten Auslöser gegebenen Öffnungstendenz der Schiebeflügel entgegenzuwirken.From the European patent application with the publication number EP 0 354 505 A2 is a sliding wall with all-glass sliding sash known which have a lowerable via a mechanism bottom seal. The mechanism includes a trigger projecting on the front side of the all-glass sliding sash, which is pressed against a triggering spring force of the lowering mechanism when closing the sliding door. The all-glass sliding sash have a locking mechanism with a magnetic strip to counteract, inter alia, given by the spring-loaded release opening tendency of the sliding sash.

Die Magnetleisten erstrecken sich über die Vertikalabschnitte der Randeinfassung der Ganzglas-Schiebeflügel und sorgen für ein dichtes aneinanderliegen der Schiebeflügel im geschlossenen Zustand der Schiebewand. Das die magnetischen Kräfte der Öffnungstendenz der Schiebeflügel aufgrund der auf den Auslöser der Bodendichtung Federkraft entgegenwirken ist nur ein Nebeneffekt der Magnetleisten. Für den Zweck des Entgegenwirkens gegen die Öffnungstendenz der Schiebeflügel wegen des Auslösers, wären derart große Magnete in Form von Magnetleisten nicht notwendig.. Außerdem stellen die Magnetleisten eine erhebliche Einschränkung der ästhetischen Gestaltungsmöglichkeiten bei einer Schiebetür mit einer Bodendichtung dar und erfordern einen zusätzlichen Montageaufwand.The magnetic strips extend over the vertical sections of the edge surround the all-glass sliding sash and ensure a tight abutment of the sliding sash in the closed state of the sliding wall. The counteracting the magnetic forces of the opening tendency of the sliding leaf due to the spring force on the trigger of the bottom seal is only a side effect of the magnetic strips. For the purpose of counteracting the opening tendency of the sliding sash because of the trigger, such large magnets in the form of magnetic strips would not be necessary .. In addition, the magnetic strips represent a significant limitation of the aesthetic design options in a sliding door with a bottom seal and require additional installation work.

Hier setzt die Erfindung an.This is where the invention starts.

Der Erfindung liegt das Problem zugrunde eine Dichtungsanordnung der eingangs genannten Art so zu gestalten, dass das Magnetelement oder ein Gegenstück des Magnetelement in einfache und ansprechender Art in die Dichtungsanordnung integriert ist.The invention is based on the problem of designing a sealing arrangement of the type mentioned above so that the magnetic element or a counterpart of the magnetic element is integrated into the sealing arrangement in a simple and attractive manner.

Die Lösung dieser Aufgabe liefert eine Dichtungsanordnung für eine Schiebetür der eingangs genannten Gattung mit den kennzeichnenden Merkmalen des Hauptanspruchs. Erfindungsgemäß ist vorgesehen, dass das Magnetelement oder ein Gegenstück für das Magnetelement an einem Befestigungselement, vorzugsweise an einem Befestigungswinkel angebracht ist, welches zur Befestigung der Bodendichtung an dem Türblatt dient.The solution to this problem provides a seal assembly for a sliding door of the type mentioned above with the characterizing features of the main claim. According to the invention it is provided that the magnetic element or a counterpart for the magnetic element is attached to a fastening element, preferably on a mounting bracket, which serves for fastening the bottom seal on the door leaf.

Die Magnetkraft kann erfindungsgemäß an die Auslösekraft der Bodendichtung der Schiebetür angepasst werden. Bei einer in der Auslösekraft optimierten Schiebetürdichtung liegt die Auslösekraft beispielsweise in der Größenordnung von bis zu 20 N/m. Bei herkömmlich automatisch auslösenden Bodendichtungen liegen die Auslösekräfte üblicherweise im Bereich von 20 bis 60 N, je nach Breite der Schiebetür. Dadurch dass bei der erfindungsgemäßen Lösung die Schiebetür mittels des Magnetelements in Schließrichtung gezogen wird, kann auf ein Schloss oder einen ähnlichen Schließmechanismus verzichtet werden. Allerdings sollte die Magnetkraft auch nicht zu stark gewählt werden, da sonst zum Öffnen der Schiebetür wiederum eine zu große Kraft aufzuwenden ist. Idealerweise ist also die Magnetkraft so gewählt, dass die durch den mit einer Federkraft beaufschlagten Auslöser gegebene Tendenz der Schiebetür sich zu öffnen nur etwas überkompensiert wird. Parameter, die die Magnetkraft beeinflussen sind insbesondere die Größe des Magnetelements und/oder der Werkstoff aus dem das Magnetelement besteht. Variieren lässt sich die in Schließrichtung der Schiebetür einwirkende Magnetkraft aber auch über die Größe und/oder Materialstärke des Gegenstücks. Auf diese Weise kann über das Gegenstück auch eine Feinabstimmung vorgenommen werden. Die Magnetkräfte werden durch den Magnetfluss durch den Magneten einerseits und das Gegenstück andererseits mitbestimmt. Wenn mehr Magnetkraftlinien durch beide Teile fließen können, nimmt die Magnetkraft zu. Das ideale Verhältnis liegt etwa vor, wenn Magnetelement und Gegenstück etwa gleiche Materialstärke aufweisen. Wird das Gegenstück dünner gewählt, reduziert sich die Magnetkraft. Somit kann man beispielsweise durch einfaches Austauschen unterschiedlich starker beispielsweise etwa plattenförmiger metallischer Gegenstücke die erforderliche Haltekraft des Magneten anpassen.The magnetic force can be adapted according to the invention to the release force of the bottom seal of the sliding door. For example, with a sliding door seal optimized in the release force, the release force is on the order of up to 20 N / m. In conventional automatically triggering bottom seals, the release forces are usually in the range of 20 to 60 N, depending on the width of the sliding door. The fact that in the solution according to the invention, the sliding door is pulled by means of the magnetic element in the closing direction, can be dispensed with a lock or a similar locking mechanism. However, the magnetic force should not be too strong, otherwise there will be too much force to open the sliding door. Ideally, therefore, the magnetic force is chosen so that the given by the acted upon by a spring trigger trigger tendency of the sliding door to open only slightly overcompensated. Parameters that influence the magnetic force are in particular the size of the magnetic element and / or the material of which the magnetic element is made. Vary the magnetic force acting in the closing direction of the sliding door but also on the size and / or material thickness of the counterpart. In this way, via the counterpart also a fine-tuning can be made. The magnetic forces are determined by the magnetic flux through the magnet on the one hand and the counterpart on the other hand. If more Magnetic force lines can flow through both parts, the magnetic force increases. The ideal ratio is approximately when the magnetic element and counterpart have approximately the same thickness. If the counterpart is chosen thinner, the magnetic force is reduced. Thus, one can adjust the required holding force of the magnet, for example, by simply exchanging differently strong, for example, approximately plate-shaped metallic counterparts.

Gemäß einer bevorzugten Weiterbildung der Erfindung kann man die als Gegenstück verwendete Platte auch gleichzeitig als Widerlager für den Auslöser der absenkbaren Bodendichtung verwenden.According to a preferred embodiment of the invention, you can also use the plate used as a counterpart at the same time as an abutment for the trigger of the lowerable bottom seal.

Die Bodendichtung kann beispielsweise über einen Befestigungswinkel am Türblatt befestigt sein. Das Gegenstück wird vorzugsweise an dem Rahmen oder an der Zarge angebracht, gegen die die Schiebetür schließt. Grundsätzlich ist es aber auch möglich, die Position von Magnetelement und Gegenstück zu vertauschen, so dass sich das Magnetelement an der Zarge befindet. Eine mögliche bevorzugte konstruktive Variante sieht beispielsweise vor, dass das Magnetelement mindestens teilweise in eine Nut des Türblatts oder der Zarge eingelassen ist. Dabei kann das Magnetelement auch beispielsweise über ein Federelement in einer solchen Nut des Türblatts oder der Zarge axial federnd gelagert sein. Dadurch ist es möglich, das Magnetelement etwas gegenüber dem Türblatt oder der Zarge vorstehen zu lassen und beim Schließen der Schiebetür federt das Magnetelement dann etwas in die Nut zurück.The bottom seal may for example be attached via a mounting bracket on the door leaf. The counterpart is preferably attached to the frame or to the frame against which the sliding door closes. In principle, it is also possible to exchange the position of the magnetic element and counterpart, so that the magnetic element is located on the frame. A possible preferred structural variant provides, for example, that the magnetic element is at least partially embedded in a groove of the door leaf or the frame. In this case, the magnetic element may also be mounted axially resilient, for example via a spring element in such a groove of the door leaf or the frame. This makes it possible to slightly protrude the magnetic element relative to the door leaf or the frame and when closing the sliding door, the magnetic element then springs back slightly into the groove.

Das Magnetelement kann am Türblatt in die Befestigungseinrichtung integriert werden. Das Magnetelement kann an dem Türblatt beispielsweise über eine Schraube oder über eine Klebeverbindung angebracht werden. Das Magnetelement kann gemäß einer bevorzugten Weiterbildung der Erfindung etwa scheibenförmig oder etwa ringförmig ausgebildet sein, wobei man das Magnetelement beispielsweise etwa mittig lochen und dann mit einer Befestigungsschraube oder einem ähnlichen Befestigungselement zusammen mit dem Befestigungswinkel stirnseitig am Türblatt anbringen kann.The magnetic element can be integrated on the door leaf in the fastening device. The magnetic element can be attached to the door leaf, for example via a screw or via an adhesive connection. The magnetic element can according to a preferred embodiment of the invention as disc-shaped or approximately annular, wherein the magnetic element, for example, approximately centrally punch and then attach with a mounting screw or a similar fastener together with the mounting bracket frontally on the door leaf.

Eine bevorzugte Weiterbildung der erfindungsgemäßen Aufgabenlösung sieht vor, dass das Magnetelement in einen Befestigungswinkel, der zur Anbringung der absenkbaren Bodendichtung am Türblatt dient, integriert ist. Dieser Befestigungswinkel kann beispielsweise auch ein Langloch aufweisen, so dass es möglich ist, den Befestigungswinkel in winkliger Lage bezogen auf das Türblatt an diesem zu befestigen und dadurch eine schiefe Ebene zu erzeugen oder aber eine etwas schief eingebaute Tür dadurch auszugleichen. Durch ein solches Langloch in einem Befestigungswinkel kann man auch die Bodendichtung für die Schiebetür bewusst etwas schief einbauen.A preferred embodiment of the task solution according to the invention provides that the magnetic element is integrated in a mounting bracket which serves for mounting the lowerable floor seal on the door leaf. This mounting bracket may for example also have a slot, so that it is possible to fix the mounting bracket in an angular position relative to the door leaf on this and thereby produce an inclined plane or compensate for a slightly wrong built door thereby. By such a slot in a mounting bracket you can also deliberately install the bottom seal for the sliding door something wrong.

Da die sogenannte Zargenluft, das heißt der Abstand zwischen dem Türblatt und der Zarge variieren kann oder auch das Türblatt nicht immer so eingebaut ist, dass es parallel zur Ebene der Zarge verläuft, ist es vorteilhaft, wenn das Magnetelement axial federnd gelagert ist.Since the so-called Zargenluft, that is, the distance between the door leaf and the frame may vary or the door leaf is not always installed so that it is parallel to the plane of the frame, it is advantageous if the magnetic element is axially resiliently mounted.

Eine Grobeinstellung der Magnetkraft kann beispielsweise herstellerseitig erfolgen, je nachdem welche Länge die jeweilige Bodendichtung aufweist, indem die jeweilige Größe des Magnetelements und der Werkstoff aus dem dieses besteht entsprechend gewählt wird. Die Feinabstimmung kann dann gegebenenfalls vor Ort durch den Monteur erfolgen, beispielsweise in der bereits erwähnten Weise über die jeweilige Auswahl der Größe und der Materialstärke des Gegenstücks.A coarse adjustment of the magnetic force can for example be made by the manufacturer, depending on the length of the respective bottom seal, by the respective size of the magnetic element and the material from which this is selected accordingly. The fine tuning can then optionally be done on site by the installer, for example in the manner already mentioned on the respective selection of the size and the material thickness of the counterpart.

Zunächst wird auf Fig. 1 Bezug genommen. Die Darstellung zeigt eine vereinfachte perspektivische Ansicht des unteren Bereichs eines Türblatts 11, wobei man etwa auf die Stirnseite des Türblatts schaut. Man erkennt, dass eine absenkbare Bodendichtung vorhanden ist, die insgesamt mit 16 bezeichnet ist und die in eine Nut 16a des Türblatts 11 eingelassen ist. Diese absenkbare Bodendichtung 16 umfasst ein Dichtungsprofil 16b, welches in der abgesenkten Stellung der Dichtung auf dem Untergrund zur Anlage kommt und somit den unteren Türspalt abdichtet. Ausgelöst wird die Absenkbewegung über den stirnseitig am Türblatt 11 vorstehenden Auslöser 20, der beim Schließen der Tür eingedrückt wird und dann einen hier nicht näher beschriebenen federbetätigten Absenkmechanismus dazu veranlasst in an sich bekannter Weise das Dichtungsprofil 16b abzusenken. Da der Auslöser 20 von einer Federkraft des Absenkmechanismus beaufschlagt wird und es sich um eine Schiebetür handelt führt dies dazu, dass die Federn versuchen, den Auslöser 20 in die Ausgangsstellung zurückzudrängen (siehe dazu auch Fig. 2), in der der Auslöser 20 ein Stück stirnseitig am Türblatt 11 vorsteht und in der die Federn des Absenkmechanismus entspannt sind. Dies führt zu einer Öffnungstendenz der Schiebetür, weshalb bei den herkömmlichen Schiebetüren mit Bodendichtung meist eine Verriegelung vorhanden ist, die verhindert, dass sich die Schiebtür selbsttätig öffnet.First, it will open Fig. 1 Referenced. The illustration shows a simplified perspective view of the lower portion of a door leaf 11, looking approximately at the front side of the door leaf. It can be seen that a lowerable bottom seal is present, which is designated overall by 16 and which is embedded in a groove 16a of the door leaf 11. This lowerable bottom seal 16 comprises a sealing profile 16b, which comes into abutment in the lowered position of the seal on the ground and thus seals the lower door gap. The lowering movement is triggered via the end face on the door leaf 11 protruding trigger 20, which is pressed when closing the door and then causes a not described here spring-operated lowering mechanism to lower in a conventional manner, the sealing profile 16b. Since the trigger 20 is acted upon by a spring force of the Absenkmechanismus and it is a sliding door, this causes the springs try to push the trigger 20 back to the starting position (see also Fig. 2 ), in which the trigger 20 protrudes a piece on the front side of the door leaf 11 and in which the springs of the lowering mechanism are relaxed. This leads to an opening tendency of the sliding door, which is why in the conventional sliding doors with bottom seal usually a lock is present, which prevents the sliding door opens automatically.

Das Ausführungsbeispiel nach Fig. 1 und 2 sieht nun vor, dass ein Magnetelement 12 vorhanden ist, welches sich in einer Nut 13 des Türblatts befindet. An der hier nicht dargestellten Türzarge befindet sich ein entsprechendes Gegenstück (siehe Bezugszeichen 21 in Fig. 4), so dass das Türblatt 11 durch die Magnetkraft, die die Federkraft, welche auf den Auslöser 20 einwirkt, überkompensiert, in die Schließstellung gezogen wird und in der Schließstellung verbleibt.The embodiment according to Fig. 1 and 2 now provides that a magnetic element 12 is present, which is located in a groove 13 of the door leaf. At the door frame, not shown here is a corresponding counterpart (see reference numeral 21 in Fig. 4 ), so that the door leaf 11 is overcompensated by the magnetic force which overcompensates the spring force acting on the trigger 20, is moved to the closed position and remains in the closed position.

Wie man aus Fig. 1 erkennt, handelt es sich bei dem Magnetelement 12 um ein im Umriss beispielsweise kreisrundes Magnetstück, welches etwa scheibenförmig ausgebildet ist (siehe auch Fig. 2). Das Magnetelement 12 befindet sich oberhalb eines Befestigungswinkels 15, mittels dessen die absenkbare Bodendichtung 16 am Türblatt 11 befestigt wird.How to get out Fig. 1 detects, it is in the magnetic element 12 is an outline, for example, circular magnetic piece, which is approximately disc-shaped (see also Fig. 2 ). The magnetic element 12 is located above a mounting bracket 15, by means of which the lowerable floor seal 16 is attached to the door leaf 11.

Fig. 2 zeigt, dass das Magnetelement 12 teilweise von der Nut 13 aufgenommen wird, bei geöffneter Tür aber ein Stück gegenüber dem Türblatt 11 stirnseitig vorstehen kann. Das Magnetelement 12 ist beispielsweise mittels einer Schraube 17 am Türblatt befestigt. Diese Schraube 17 kann sich durch das scheibenartige Magnetelement 12 hindurch erstrecken. In dem Ausführungsbeispiel gemäß Fig. 2 ist außerdem eine Feder 14, beispielsweise eine Spiralfeder vorgesehen, die die Schraube 17 umgibt und in der Nut 13 zwischen Magnetelement 12 und Nutgrund angeordnet ist. Dadurch ist das Magnetelement 12 gegen die Kraft der Feder 14 nachgiebig federnd gelagert. Wenn das Magnetelement 12 ein Stück weiter vorsteht als in der Zeichnung Fig. 2 gezeigt, ist dies somit unerheblich. Man kann somit auch Toleranzen im Abstandsmaß zwischen der Stirnseite des Türblatts 11 und dem Türrahmen, gegen den die Schiebetür schließt, ausgleichen. Aufgrund der Magnetkraft wird das Magnetelement 12 gegebenenfalls auch gegen die Federkraft 14 aus der Nut 13 herausgezogen, wenn es in die Nähe des Gegenstücks gelangt, so dass man auch hier Toleranzen überbrücken kann. Der Befestigungswinkel 15 wird bei dieser Variante der Erfindung beispielsweise über eine weitere Schraube 18 am Türblatt 11 festgeschraubt, um die Bodendichtung 16 zu befestigen. Fig. 2 shows that the magnetic element 12 is partially received by the groove 13, with the door open but a piece opposite to the Door leaf 11 can protrude frontally. The magnetic element 12 is fastened to the door leaf, for example, by means of a screw 17. This screw 17 may extend through the disc-like magnetic element 12 therethrough. In the embodiment according to Fig. 2 In addition, a spring 14, for example, a coil spring is provided, which surrounds the screw 17 and is arranged in the groove 13 between the magnetic element 12 and groove bottom. As a result, the magnetic element 12 is resiliently mounted resiliently against the force of the spring 14. When the magnetic element 12 protrudes a little further than in the drawing Fig. 2 this is therefore irrelevant. It is therefore also possible to compensate for tolerances in the distance between the end face of the door leaf 11 and the door frame against which the sliding door closes. Due to the magnetic force, the magnetic element 12 is optionally pulled out against the spring force 14 from the groove 13 when it comes in the vicinity of the counterpart, so that you can bridge tolerances here. The mounting bracket 15 is screwed in this variant of the invention, for example, via a further screw 18 on the door leaf 11 to secure the bottom seal 16.

Eine davon etwas abweichende konstruktive Lösung gemäß der Erfindung zeigt das Ausführungsbeispiel gemäß den Fig. 3 und 4. Bei dieser Variante ist das Magnetelement 12 mit dem Befestigungswinkel 15 zu einem Bauelement kombiniert. Man kann dadurch mit nur einer Befestigungsschraube 17, die durch das Magnetelement 12 und auch den Befestigungswinkel 15 hindurchgeschraubt ist (siehe Fig. 4) gleichzeitig das Magnetelement 12 und die Bodendichtung 16 befestigen. Das scheibenförmige Magnetelement 12 mit mittiger Bohrung für die Befestigungsschraube 17 kann beispielsweise auf den Befestigungswinkel 15 aufgeklebt sein.One of them slightly different constructive solution according to the invention shows the embodiment according to the 3 and 4 , In this variant, the magnetic element 12 is combined with the mounting bracket 15 to form a component. It can be characterized by only one fastening screw 17 which is screwed through the magnetic element 12 and the mounting bracket 15 (see Fig. 4 ) simultaneously fix the magnetic element 12 and the bottom seal 16. The disc-shaped magnetic element 12 with a central bore for the fastening screw 17 may be glued to the mounting bracket 15, for example.

Fig. 4 zeigt auch das Gegenstück 21 in Form einer Metallplatte, die sich an dem Rahmen oder der Zarge 22 für die Schiebetür befindet. In Fig. 4 kann man auch gut erkennen, dass in der Schließstellung zwischen Zarge 22 und Türblatt 11 ein Spalt verbleibt, der durch das Gegenstück 21 und das etwas gegenüber dem Türblatt 11 vorstehende Magnetelement 12 überbrückt wird. Der Auslöser 20 befindet sich in seiner eingedrückten Betätigungsstellung, wie man gut durch Vergleich von Fig. 4 und Fig. 2 erkennen kann und die Bodendichtung 16 ist in die Schließstellung abgesenkt, in der sie zum Untergrund 23 hin abdichtet, Fig. 4 also shows the counterpart 21 in the form of a metal plate, which is located on the frame or the frame 22 for the sliding door. In Fig. 4 can also be seen well that in the closed position between the frame 22 and door leaf 11, a gap remains, which is bridged by the counterpart 21 and the slightly opposite the door leaf 11 projecting magnetic element 12. The trigger 20 is in its depressed operating position, as can be well by comparing Fig. 4 and Fig. 2 can recognize and the bottom seal 16 is lowered into the closed position in which it seals to the ground 23 out,

Nachfolgend wird ein zweites erfindungsgemäßes Ausführungsbeispiel der Erfindung beschrieben. Diese Ausführungsvariante ähnelt der zuvor unter Bezugnahme auf die Fig. 3 und 4 beschriebene Variante. Jedoch weist der Befestigungswinkel 15 ein Langloch auf. Dadurch ist es zum einen möglich, das Magnetelement 12 über die Befestigungsschraube 17 in unterschiedlichen Höhenstellungen festzulegen und somit die Höhe des Magnetelements 12 bezogen auf den Befestigungswinkel 15 zu variieren. Es kann sich am Türblatt 11 eine Vertiefung befinden, so dass der Befestigungswinkel 15 in etwas eingelassener Stellung am Türblatt 11 angebracht werden kann. An dem unteren horizontalen Schenkel des Befestigungswinkels kann die Bodendichtung 16 festgelegt werden.Hereinafter, a second embodiment of the invention according to the invention will be described. This embodiment is similar to that previously described with reference to FIGS 3 and 4 described variant. However, the mounting bracket 15 has a slot. This makes it possible, on the one hand, to fix the magnetic element 12 via the fastening screw 17 in different height positions and thus to vary the height of the magnetic element 12 relative to the fastening angle 15. It can be located on the door panel 11 a recess, so that the mounting bracket 15 can be mounted in slightly recessed position on the door panel 11. At the lower horizontal leg of the mounting bracket, the bottom seal 16 can be set.

Das am Befestigungswinkel 15 vorhandene Langloch bietet außerdem die Möglichkeit, beispielsweise die Bodendichtung 16 in gegenüber der Horizontalen und dem Türblatt 11 etwas geneigter (schiefer) Lage einzubauen, wenn beispielsweise der untere Türspalt über die Länge der Schiebetür unterschiedlich breit ist. Es kann auch sinnvoll sein, über den Befestigungswinkel 15 eine schiefe Ebene zu erzeugen, wenn beispielsweise das Türblatt etwas schief eingebaut ist, das heißt, die Stirnseite des Türblatts 11 nicht exakt parallel zum Rahmen der Schiebetür verläuft. Auch bei dieser Variante ist das Magnetelement 12 scheibenförmig ausgebildet mit einer etwa mittigen Bohrung, so dass die Befestigungsschraube 17 durch diese Bohrung und das Langloch hindurch in den Bereich der Vertiefung des Türblatts 11 eingeschraubt werden kann.The present at the mounting bracket 15 slot also offers the possibility, for example, the bottom seal 16 in relation to the horizontal and the door leaf 11 slightly inclined (slate) to install position, for example, if the lower door gap over the length of the sliding door is different widths. It may also be useful to about the mounting bracket 15 an inclined plane produce, for example, if the door leaf is installed somewhat obliquely, that is, the end face of the door leaf 11 is not exactly parallel to the frame of the sliding door. Also in this variant, the magnetic element 12 is disc-shaped with an approximately central bore, so that the fastening screw 17 can be screwed through this hole and the slot in the region of the recess 11 of the door panel.
