Definitions

  • the invention relates to a sealing device for doors according to the preamble of claim 1.
  • sealing devices are used to seal the gap between the floor and the bottom edge of the door when the door is closed.
  • the sealing body is arranged in a groove on the lower horizontal edge of the door. The sealing body is held in the rest position in the groove under the force of compression springs. A soft iron pole is fastened in the sealing body, via which the sealing body with the electromagnet is tightened when the door is closed. If the sealing body is long enough, larger magnetic forces and thus correspondingly stronger electromagnets must be used. If the compression springs weaken or even fail, the sealing body can no longer return to its rest position. Then he stands down over the lower edge of the door and grinds on the floor. This will not only damage the sealing body, but also the floor covering. In addition, the groove can only be provided in the door in a complex manner.
  • the sealing body is only mechanical adjusted.
  • it has tabs on which angle levers are articulated. They engage in openings in a connecting rod, which protrudes with one end over the vertical door edge on the closing side. If the door is closed, the connecting rod is pushed back against the force of compression springs, whereby the sealing body is moved downwards into the sealing position via the angle lever.
  • the sealing device is housed in a U-shaped holding rail, which must be attached to the lower horizontal door edge. A corresponding processing of this door edge is necessary for this.
  • the invention has for its object to design the generic sealing device so that it is exposed to little wear and can be assembled without machining the door.
  • the lifting device is interposed between the electromagnet and the sealing body, with which the sealing body is adjusted from its rest position to its sealing position.
  • the switch is actuated, which turns on the electromagnet.
  • the armature is thereby attracted and the swivel arm is pivoted via the connecting element.
  • the lifting member provided on the swivel arm is adjusted accordingly and interacts with the gradient member provided on the sealing body.
  • the sealing body is mechanically adjusted from its rest position to its sealing position. If the sealing body is housed in the floor, it is lifted in by the lifting member adjusted its sealing position. If the door is opened and the electromagnet is switched off accordingly, the sealing body can return to its rest position under its own weight.
  • the sealing device can be accommodated in the door opening limitation so that the door to be sealed itself does not have to be machined, in particular does not have to be provided with a groove for receiving the sealing device. Since the sealing body is not adjusted magnetically but mechanically into its sealing position by means of the lifting device, correspondingly low-power electromagnets are sufficient to actuate the armature, which can thereby also be made very compact.
  • the sealing device according to the invention is not only suitable for conventional revolving doors, but also for sliding doors, folding walls and the like, since the sealing device is no longer accommodated in the door itself.
  • the sealing body can therefore be designed so that its floor plan corresponds to the door to be sealed, folding wall and the like.
  • the sealing device according to the invention can be provided not only in the floor, but also, for example, in the ceiling construction or in the vertically running edges of the door or wall opening.
  • the sealing device serves for sealing at the lower edge of revolving doors, sliding doors, folding walls and the like. It has a holder 1 (FIG. 3), which is not shown in FIGS. 1 and 2.

Abstract

The sealing arrangement is used for closed doors to seal the gap between the floor and the lower edge of the door. A switch for an electromagnet (55) is assigned to a sealing body (23) as a triggering element for moving said body into the sealing position. The switch is connected to the sealing body (23) via a lifting device (29, 30) having an armature (44). By means of the switch, the electromagnet (55) is excited upon closure of the door, then draws the armature (44) and moves the sealing body (23) out of a support (1) via the lifting device (29, 30) and into the sealing position. <IMAGE>

Description

Die Erfindung betrifft eine Dichtungseinrichtung für Türen nach dem Oberbegriff des Anspruches 1.The invention relates to a sealing device for doors according to the preamble of claim 1.

Solche Dichtungseinrichtungen werden verwendet, um bei geschlossener Tür den Spalt zwischen Fußboden und Türunterkante abzudichten. Bei der gattungsgemäßen Dichtungseinrichtung (DE-A-2 509 958) ist der Dichtungskörper in einer Nut am unteren horizontalen Rand der Tür angeordnet. Der Dichtungskörper wird unter der Kraft von Druckfedern in seiner Ruhelage in der Nut gehalten. Im Dichtungskörper ist ein Weicheisenpol befestigt, über den der Dichtungskörper mit dem Elektromagneten beim Schließen der Tür angezogen wird. Ist der Dichtungskörper entsprechend lang, müssen größere Magnetkräfte und damit auch entsprechend stärkere Elektromagnete eingesetzt werden. Sollten die Druckfedern erlahmen oder gar ausfallen, kann der Dichtungskörper nicht mehr in seine Ruhelage gelangen. Dann steht er nach unten über den unteren Türrand vor und schleift am Boden. Dadurch wird nicht nur der Dichtungskörper, sondern auch der Fußbodenbelag beschädigt. Außerdem läßt sich die Nut nur in aufwendiger Weise in der Tür vorsehen.Such sealing devices are used to seal the gap between the floor and the bottom edge of the door when the door is closed. In the generic sealing device (DE-A-2 509 958) the sealing body is arranged in a groove on the lower horizontal edge of the door. The sealing body is held in the rest position in the groove under the force of compression springs. A soft iron pole is fastened in the sealing body, via which the sealing body with the electromagnet is tightened when the door is closed. If the sealing body is long enough, larger magnetic forces and thus correspondingly stronger electromagnets must be used. If the compression springs weaken or even fail, the sealing body can no longer return to its rest position. Then he stands down over the lower edge of the door and grinds on the floor. This will not only damage the sealing body, but also the floor covering. In addition, the groove can only be provided in the door in a complex manner.

Bei einer anderen bekannten Dichtungseinrichtung (FR-A-1 434 355) wird der Dichtungskörper lediglich mechanisch verstellt. Er weist hierzu Laschen auf, an denen Winkelhebel angelenkt sind. Sie greifen in Öffnungen einer Verbindungsstange ein, die mit ihrem einen Ende über den schließseitigen vertikalen Türrand ragt. Wird die Tür geschlossen, wird die Verbindungsstange gegen die Kraft von Druckfedern zurückgeschoben, wodurch über die Winkelhebel der Dichtungskörper nach unten in die Dichtlage verstellt wird. Die Dichtungseinrichtung ist in einer U-förmigen Halteschiene untergebracht, die am unteren horizontalen Türrand befestigt werden muß. Hierzu ist eine entsprechende Bearbeitung dieses Türrandes erforderlich.In another known sealing device (FR-A-1 434 355) the sealing body is only mechanical adjusted. For this purpose, it has tabs on which angle levers are articulated. They engage in openings in a connecting rod, which protrudes with one end over the vertical door edge on the closing side. If the door is closed, the connecting rod is pushed back against the force of compression springs, whereby the sealing body is moved downwards into the sealing position via the angle lever. The sealing device is housed in a U-shaped holding rail, which must be attached to the lower horizontal door edge. A corresponding processing of this door edge is necessary for this.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Dichtungseinrichtung so auszubilden, daß sie nur einem geringen Verschleiß ausgesetzt ist und ohne Bearbeitung der Tür montiert werden kann.The invention has for its object to design the generic sealing device so that it is exposed to little wear and can be assembled without machining the door.

Diese Aufgabe wird bei der gattungsgemäßen Dichtungseinrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic sealing device according to the invention with the characterizing features of claim 1.

Bei der erfindungsgemäßen Dichtungseinrichtung ist zwischen dem Elektromagneten und dem Dichtungskörper die Hubeinrichtung zwischengeschaltet, mit welcher der Dichtungskörper aus der Ruhelage in seine Dichtlage verstellt wird. Beim Schließen der Tür wird der Schalter betätigt, wodurch der Elektromagnet eingeschaltet wird. Der Anker wird dadurch angezogen, und über das Verbindungselement wird der Schwenkarm verschwenkt. Das am Schwenkarm vorgesehene Hubglied wird entsprechend verstellt und wirkt mit dem Steigungsglied zusammen, das am Dichtungskörper vorgesehen ist. Dadurch wird der Dichtungskörper mechanisch aus der Ruhelage in seine Dichtlage verstellt. Ist der Dichtungskörper im Fußboden untergebracht, dann wird er durch das Hubglied aufwärts in seine Dichtlage verstellt. Wird die Tür geöffnet und dementsprechend der Elektromagnet abgeschaltet, kann der Dichtungskörper unter seinem Eigengewicht wieder in seine Ruhelage zurückkehren. Dadurch ist auf jeden Fall sichergestellt, daß der Dichtungskörper zuverlässig in seine Ruhelage gelangt. Die Dichtungseinrichtung kann in der Türöffnungsbegrenzung untergebracht werden, so daß die abzudichtende Tür selbst nicht bearbeitet, insbesondere nicht mit einer Nut zur Aufnahme der Dichtungseinrichtung versehen werden muß. Da der Dichtungskörper nicht magnetisch, sondern mittels der Hubeinrichtung rein mechanisch in seine Dichtlage verstellt wird, genügen zum Betätigen des Ankers entsprechend leistungsschwache Elektromagneten, die dadurch auch sehr kompakt ausgebildet sein können. Die erfindungsgemäße Dichtungseinrichtung ist nicht nur für herkömmliche Drehtüren, sondern auch für Schiebetüren, Faltwände und dgl. geeignet, da die Dichtungseinrichtung nicht mehr in der Tür selbst untergebracht ist. Der Dichtungskörper kann darum so gestaltet werden, daß sein Grundriß der jeweils abzudichtenden Tür, Faltwand und dgl. entspricht. Die erfindungsgemäße Dichtungseinrichtung kann nicht nur im Fußboden, sondern beispielsweise auch in der Deckenkonstruktion oder in den vertikal verlaufenden Rändern der Tür- oder Wandöffnung vorgesehen werden.In the sealing device according to the invention, the lifting device is interposed between the electromagnet and the sealing body, with which the sealing body is adjusted from its rest position to its sealing position. When the door is closed, the switch is actuated, which turns on the electromagnet. The armature is thereby attracted and the swivel arm is pivoted via the connecting element. The lifting member provided on the swivel arm is adjusted accordingly and interacts with the gradient member provided on the sealing body. As a result, the sealing body is mechanically adjusted from its rest position to its sealing position. If the sealing body is housed in the floor, it is lifted in by the lifting member adjusted its sealing position. If the door is opened and the electromagnet is switched off accordingly, the sealing body can return to its rest position under its own weight. This ensures in any case that the sealing body reliably comes to its rest position. The sealing device can be accommodated in the door opening limitation so that the door to be sealed itself does not have to be machined, in particular does not have to be provided with a groove for receiving the sealing device. Since the sealing body is not adjusted magnetically but mechanically into its sealing position by means of the lifting device, correspondingly low-power electromagnets are sufficient to actuate the armature, which can thereby also be made very compact. The sealing device according to the invention is not only suitable for conventional revolving doors, but also for sliding doors, folding walls and the like, since the sealing device is no longer accommodated in the door itself. The sealing body can therefore be designed so that its floor plan corresponds to the door to be sealed, folding wall and the like. The sealing device according to the invention can be provided not only in the floor, but also, for example, in the ceiling construction or in the vertically running edges of the door or wall opening.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention result from the further claims, the description and the drawings.

Die Dichtungseinrichtung dient zum Abdichten am unteren Rand von Drehtüren, Schiebetüren, Faltwänden und dgl. Sie hat eine Halterung 1 (Fig.3), die in den Fig.1 und 2 nicht dargestellt ist. Im Ausführungsbeispiel wird die Halterung 1 durch eine U-Schiene gebildet, die sich über die ganze Lange der Dichtungseinrichtung erstreckt. Anstelle der U-Schiene kann die Halterung auch aus einzelnen U-förmigen Schienenabschnitten 1a bestehen (Fig.4), die mit Abstand längs der Dichtungseinrichtung angeordnet sind. Die Halterung 1 liegt mit einem Quersteg 2 auf einem Rohfußboden 3 auf und ist mit Dübeln 4 und dgl. am Fußboden 3 befestigt. Um Neigungen des Fußbodens 3 einfach ausgleichen zu können, sind im Bereich beiderseits der Dübel 4 Stellschrauben 5 in den Quersteg 2 geschraubt. Sie können sich auf dem Fußboden 3 abstützen, so daß durch Heraus- oder Eindrehen dieser Stellschrauben 5 die Halterung 1 bezüglich des Fußbodens 3 einfach justiert werden kann. Im Ausführungsbeispiel ist auf dem Fußboden 3 ein Fußbodenbelag 6 aufgebracht, beispielsweise ein Teppichboden. Seine Oberseite ist mit 7 bezeichnet. Es ist aber auch möglich, die Halterung 1 versenkt direkt im Boden 3 anzuordnen.The sealing device serves for sealing at the lower edge of revolving doors, sliding doors, folding walls and the like. It has a holder 1 (FIG. 3), which is not shown in FIGS. 1 and 2. In the exemplary embodiment, the holder 1 is formed by a U-rail, which extends over the entire length of the sealing device. Instead of the U-rail, the holder can also consist of individual U-shaped rail sections 1a (FIG. 4), which are arranged at a distance along the sealing device. The bracket 1 lies with a crossbar 2 on a raw floor 3 and is fastened to the floor 3 with dowels 4 and the like. In order to be able to easily compensate for inclinations of the floor 3, 4 set screws 5 are screwed into the crossbar 2 in the area on both sides of the dowels. They can be supported on the floor 3, so that the holder 1 can be easily adjusted with respect to the floor 3 by unscrewing or screwing in these adjusting screws 5. In the exemplary embodiment, a floor covering 6 is applied to the floor 3, for example a carpet. Its top is labeled 7. But it is also possible to arrange the holder 1 sunk directly in the floor 3.

Die Schenkel 8,9 der Halterung 1 sind aufwärts gerichtet und enden mit Abstand von der Oberseite 7 des Fußbodenbelages 6. Dadurch ist die Halterung 1 verdeckt im Fußbodenbelag 6 untergebracht, so daß sie bei geöffneter Tür 10 nicht stört.The legs 8.9 of the bracket 1 are directed upward and end at a distance from the top 7 of the floor covering 6. As a result, the bracket 1 is concealed in the floor covering 6 so that it does not interfere with the door 10 open.

Zwischen den Schenkeln 8,9 ist ein Führungskörper 11 befestigt, der ebenfalls als U-Schiene ausgebildet ist, deren aufwärts gerichtete Schenkel 12,13 an den Innenseiten der Schenkel 8,9 der Halterung 1 anliegen. Die Schenkel 12,13 enden in der Oberseite 7 des Fußbodenbelages 6. Ein Quersteg 14 des Führungskörpers 11 liegt mit Abstand oberhalb des Quersteges 2 der Halterung 1. Damit der Führungskörper 11 genau gegenüber der Halterung 1 sowie der Oberseite 7 des Fußbodenbelages 6 ausgerichtet werden kann, sind die Schenkel 8,9 der Halterung 1 mit senkrecht verlaufenden Längsschlitzen 15 (Fig.4) versehen, durch welche in die Schenkel 12,13 des Führungskörpers 11 geschraubte Schrauben 16 ragen. Nach Lockern der Schrauben 16 kann der Führungskörper 11 relativ zur Halterung 1 verschoben werden, so daß er sich einwandfrei an Ort und Stelle genau ausrichten läßt. Dann werden die Schrauben 16 lediglich fest angezogen, um den Führungskörper fest an der Halterung zu befestigen. Die Längsschlitze 15 sind nahe den freien Enden der Schenkel 7,8 der Halterung 1 vorgesehen. Dies hat zur Folge, daß beim Anziehen der Schrauben 16 die Schenkel gegen den Führungskörper 11 gebogen werden, wodurch die Befestigung des Führungskörpers 11 verbessert wird.A guide body 11 is fastened between the legs 8, 9, which is also designed as a U-rail, the upward legs 12, 13 of which are on the inside the legs 8,9 of the holder 1 rest. The legs 12, 13 end in the upper side 7 of the floor covering 6. A transverse web 14 of the guide body 11 lies at a distance above the transverse web 2 of the holder 1. So that the guide body 11 can be aligned exactly with respect to the holder 1 and the upper side 7 of the floor covering 6 , The legs 8, 9 of the holder 1 are provided with vertical longitudinal slots 15 (FIG. 4), through which screws 16 project into the legs 12, 13 of the guide body 11. After loosening the screws 16, the guide body 11 can be moved relative to the holder 1, so that it can be precisely aligned in place. Then the screws 16 are only tightened firmly to fix the guide body to the bracket. The longitudinal slots 15 are provided near the free ends of the legs 7, 8 of the holder 1. This has the consequence that when tightening the screws 16, the legs are bent against the guide body 11, whereby the fastening of the guide body 11 is improved.

Im Führungskörper 11 ist unter Zwischenlage einer Dämpfungsschicht 17, die auf dem Quersteg 14 des Führungskörpers aufliegt und beispielsweise durch einen Kunststoffstreifen gebildet sein kann, ein Haltekörper 18 befestigt, der vorteilhaft ebenfalls als U-Schiene ausgebildet ist. Der Haltekörper 18 liegt mit seinem Quersteg 19 auf der Dämpfungsschicht 17 auf. Die Schenkel 20, 21 des Haltekörpers 18 sind aufwärts gerichtet und liegen mit Abstand von den Schenkeln 12,13 des Führungskörpers 11. Auf den freien Enden der Schenkel 20, 21 liegt ein Quersteg 22 eines Dichtungskörpers 23 auf, dessen abwärts gerichtete Schenkel 24,25 zwischen den Schenkeln 12,13 des Führungskörpers 11 und den Schenkeln 20,21 des Haltekörpers mit geringer Spiel liegen (Fig.3). Die Schenkel 24,25 des Dichtungskörpers 23 enden mit Abstand von der Dämpfungsschicht 17.A holding body 18 is fastened in the guide body 11 with the interposition of a damping layer 17, which rests on the transverse web 14 of the guide body and can be formed, for example, by a plastic strip, which is also advantageously designed as a U-rail. The holding body 18 rests with its transverse web 19 on the damping layer 17. The legs 20, 21 of the holding body 18 are directed upward and are spaced apart from the legs 12, 13 of the guide body 11. On the free ends of the legs 20, 21 there is a transverse web 22 of a sealing body 23, the legs 24, 25 of which are directed downward lie with little play between the legs 12, 13 of the guide body 11 and the legs 20, 21 of the holding body (FIG. 3). The legs 24.25 of the sealing body 23 end at a distance from the damping layer 17.

In der in Fig.3 dargestellten Ruhelage liegt der Quersteg 22 des Dichtungskörpers 23 bündig mit der Oberseite 7 des Fußbodenbelages 6. Dadurch ist die Oberseite des Fußbodenbelages 6 im Bereich der Dichtungseinrichtung nicht unterbrochen bzw. nicht mit Absätzen versehen, so daß die Dichtungseinrichtung in der Ruhelage nicht stört.In the rest position shown in Figure 3, the transverse web 22 of the sealing body 23 is flush with the top 7 of the floor covering 6. As a result, the top of the floor covering 6 is not interrupted in the area of the sealing device or is not provided with shoulders, so that the sealing device in the Rest position does not bother.

An der Unterseite des Quersteges 22 des Dichtungskörpers 23 ist ein im Querschnitt U-förmiges Dichtungselement 26 befestigt, (Fig.3), dessen Schenkel 27,28 in Richtung auf den Quersteg 19 des Haltekörpers 18 divergieren und an den einander zugewandten Innenseiten der Schenkel 20,21 des Haltekörpers 18 unter geringer elastischer Vorspannung anliegen. Das Dichtungselement 26 besteht vorzugsweise aus schalldämpfendem Material, so daß bei geschlossener Tür kein oder nur ein sehr geringer Anteil an Schall über die Dichtungseinrichtung unter der Tür hindurch gelangen kann.A cross-sectionally U-shaped sealing element 26 is attached to the underside of the transverse web 22 of the sealing body 23 (FIG. 3), the legs 27, 28 of which diverge in the direction of the transverse web 19 of the holding body 18 and on the inner sides of the legs 20 facing one another , 21 of the holding body 18 bear under slight elastic prestress. The sealing element 26 is preferably made of sound-absorbing material, so that when the door is closed, no or only a very small proportion of sound can pass through the sealing device under the door.

Nahe den beiden Enden der Dichtungseinrichtung ist auf dem Quersteg 19 des Haltekörpers 18 jeweils eine Betätigungseinrichtung 29,30 angeordnet (Fig.1 und 2), mit denen der Dichtungskörper 23 beim Schließen der Tür 10 in seine Dichtstellung verstellt wird. Die beiden Betätigungseinrichtungen 29,30 sind gleich ausgebildet, jedoch spiegelsymmetrisch zueinander im Haltekörper 18 angeordnet. Im folgenden wird darum nur die Betätigungseinrichtung 29 im einzelnen beschrieben. Sie hat zwei parallel zueinander liegende Hebel 31,32, die mit ihrem vom Ende des Haltekörpers 18 abgewandten Ende an den Enden zweier Schwenkarme 33 und 34 angelenkt sind. Sie liegen an den einander zugewandten Innenseiten der Hebel 31,32 an (Fig.2). Auf der die Hebel 31,32 und die Schwenkarme 33,34 verbindenden Achse 35 sitzt frei drehbar eine Rolle 36.An actuating device 29, 30 is arranged on the crosspiece 19 of the holding body 18 near the two ends of the sealing device (FIGS. 1 and 2), with which the sealing body 23 is adjusted into its sealing position when the door 10 is closed. The two actuating devices 29, 30 are of identical design, but are arranged mirror-symmetrically to one another in the holding body 18. Therefore, only the actuating device 29 is described in detail below. It has two levers 31, 32 lying parallel to one another, which are articulated at the ends of two swivel arms 33 and 34 with their end facing away from the end of the holding body 18. They rest on the mutually facing inner sides of the levers 31, 32 (FIG. 2). A roller 36 sits on the axis 35 connecting the levers 31, 32 and the swivel arms 33, 34 in a freely rotatable manner.

Auf dem Quersteg 19 des Haltekörpers 18 ist eine Platte 37 befestigt, die zwei senkrecht abstehende Laschen 38 und 39 trägt. In ihnen ist eine Achse 40 gelagert, auf der die Schwenkarme 33,34 sitzen.On the crosspiece 19 of the holding body 18, a plate 37 is attached, which carries two vertically projecting tabs 38 and 39. An axis 40 is mounted in them, on which the swivel arms 33, 34 sit.

An einem der Schwenkarme 33,34 greift das eine Ende einer Zugfeder 41 an, die mit ihrem anderen Ende an der Platte 37 oder am Quersteg 19 des Haltekörpers 18 befestigt sein kann. Die Hebel 31,32 sind am anderen Ende an eine Gewindebuchse 42 angelenkt, in die eine Justierschraube 43 eines Ankers 44 eines Elektromagneten 45 geschraubt wird. Der Elektromagnet 45 ist im Haltekörper 18 nahe dessen einem Ende befestigt. Der Anker 44 wird zwischen den Schenkeln 20,21 und den Querstegen 19 und 22 geführt.One of the swivel arms 33, 34 engages one end of a tension spring 41, which can be fastened at its other end to the plate 37 or to the transverse web 19 of the holding body 18. The levers 31, 32 are articulated at the other end to a threaded bush 42 into which an adjusting screw 43 of an armature 44 of an electromagnet 45 is screwed. The electromagnet 45 is fixed in the holding body 18 near one end thereof. The armature 44 is guided between the legs 20, 21 and the crossbars 19 and 22.

Die Rolle 36 liegt an einer an der Unterseite des Quersteges 22 des Dichtungskörpers 23 befestigten Blattfeder 46 an, deren gegen den Elektromagneten 45 gerichtetes Ende schräg nach unten gegen den Quersteg 19 des Haltekörpers 18 gerichtet ist (Fig.1). Diese Abbiegung des freien Federendes 47 wird durch eine in den Quersteg 22 des Dichtungskörpers 23 geschraubte Stellschraube 48 erreicht, die am Blattfederende 47 anliegt und es je nach eingeschraubter Lage mehr oder weniger weit nach unten gegen den Quersteg 19 des Haltekörpers 18 biegt.The roller 36 rests on a leaf spring 46 fastened to the underside of the transverse web 22 of the sealing body 23, the end of which directed towards the electromagnet 45 is directed obliquely downwards against the transverse web 19 of the holding body 18 (FIG. 1). This deflection of the free spring end 47 is achieved by a set screw 48 screwed into the crossbar 22 of the sealing body 23, which abuts the leaf spring end 47 and, depending on the screwed-in position, bends it more or less downward against the crossbar 19 of the holding body 18.

Der Elektromagnet 45 ist über Zuleitungen 49 mit einem (nicht dargestellten) Schalter verbunden, der im Türrahmen vorgesehen ist und der beim Schließen der Tür 10 betätigt wird.The electromagnet 45 is connected via leads 49 to a switch (not shown) which is provided in the door frame and which is actuated when the door 10 is closed.

Die Figuren 1 bis 4 zeigen die Dichtungseinrichtung in ihrer Ruhelage, in der der Dichtungskörpers 23 mit seinem Quersteg 22 bündig mit der Oberseite 7 des Fußbodenbelages 6 ist. Wird die Tür 10 geschlossen, dann wird am Ende der Schließbewegung der im Türrahmen vorgesehene Schalter für die Elektromagneten 45 betätigt. Dadurch werden die Elektromagneten 45 an den beiden Enden des Haltekörpers 18 erregt und ziehen die Anker 44 gegen die Kraft der Zugfedern 41 an. Über die Hebel 31,32 werden die Schwenkarme 33,34 um die Achse 40 geschwenkt. Die Rollen 36 der beiden Betätigungseinrichtungen 29,30 werden hierbei mitgenommen und laufen auf das schräg nach unten gebogene Ende 47 der Blattfedern 46 auf, wodurch der Dichtungskörper 23 entsprechend der Abwinkelung des Blattfederendes 47 nach oben gegen die Tür 10 verstellt wird. Der Quersteg 22 des Dichtungskörpers 23 gelangt dann in Anlage an einen an der Türunterseite befestigten Dichtungsstreifen 50 (Fig.3), der beispielsweise aus Moosgummi bestehen kann. Dadurch ist eine einwandfreie Abdichtung gewährleistet.Figures 1 to 4 show the sealing device in its rest position, in which the sealing body 23 with its transverse web 22 is flush with the top 7 of the floor covering 6. If the door 10 is closed, then the Closing movement of the switch provided in the door frame for the electromagnet 45 is actuated. As a result, the electromagnets 45 are excited at the two ends of the holding body 18 and attract the armatures 44 against the force of the tension springs 41. The pivot arms 33, 34 are pivoted about the axis 40 via the levers 31, 32. The rollers 36 of the two actuating devices 29, 30 are taken along and run onto the end 47 of the leaf springs 46 bent obliquely downwards, as a result of which the sealing body 23 is adjusted upwards against the door 10 in accordance with the bending of the leaf spring end 47. The transverse web 22 of the sealing body 23 then comes into contact with a sealing strip 50 (FIG. 3) fastened to the underside of the door, which can consist, for example, of foam rubber. This guarantees a perfect seal.

Mit den Stellschrauben 48 kann der Hubweg des Dichtungskörpers 13 stufenlos und genau eingestellt werden, da sich der Hubweg bei vorgegebenem Stellweg der Hebel 31,32 nach dem Abwinkelungsgrad des freien Endes 47 der Blattfedern 46 bestimmt. Auf diese Weise ist es ohne Schwierigkeiten möglich, an Ort und Stelle den Hubweg des Dichtungkörpers 23 genau einzustellen. Auch nach einer Bearbeitung der Tür 10 kann der Hubweg des Dichtungskörpers 23 mit den Stellschrauben 48 einfach nachgestellt werden.With the adjusting screws 48, the stroke of the sealing body 13 can be continuously and precisely adjusted, since the stroke for a given stroke of the lever 31, 32 is determined by the degree of bending of the free end 47 of the leaf springs 46. In this way, it is possible without difficulty to precisely adjust the stroke of the sealing body 23 on the spot. Even after machining the door 10, the stroke of the sealing body 23 can be easily adjusted with the set screws 48.

Solange die Tür 10 geschlossen ist, bleiben die Elektromagneten 45 erregt und damit der Dichtungskörper 23 in seiner Dichtstellung. Wird die Tür 10 wieder geöffnet, wird der Schalter im Türrahmen freigegeben, wodurch die Elektromagneten 45 abfallen. Die Zugfedern 41 schwenken dann die Schwenkarme 33,34 zurück, wodurch die Anker 44 über die Hebel 31,32 im Führungskörper 18 in die in Fig.1 dargestellte Ausgangslage zurückgeschoben werden.As long as the door 10 is closed, the electromagnets 45 remain energized and thus the sealing body 23 in its sealing position. When the door 10 is opened again, the switch in the door frame is released, causing the electromagnets 45 to drop out. The tension springs 41 then pivot the swivel arms 33, 34 back, as a result of which the armatures 44 are pushed back into the starting position shown in FIG. 1 via the levers 31, 32 in the guide body 18.

Die Rollen 36 kommen von den abgebogenen Enden 47 der Blattfedern 46 frei, woduch der Dichtungskörper 23 unter seinem Eingengewicht wieder nach unten in seine Ruhelage (Fig.3) zurückfällt. Für die Schwenkarme 33,34 ist an den Laschen 38,39 ein Anschlag vorgesehen, der die Endstellung dieser Schwenkarme bestimmt. Ein solcher Anschlag kann aber auch für den Anker 44 vorgesehen sein, woduch ebenfalls die Ausgangslage der Betätigungseinrichtungen 29,30 bestimmt werden kann.The rollers 36 come free from the bent ends 47 of the leaf springs 46, whereby the sealing body 23 falls back down to its rest position (FIG. 3) under its own weight. For the swivel arms 33, 34, a stop is provided on the tabs 38, 39, which determines the end position of these swivel arms. Such a stop can also be provided for the armature 44, whereby the starting position of the actuating devices 29, 30 can also be determined.

Um beim Anziehen der Elektromagneten 45 das Anschlaggeräusch der Anker 44 zu verringern, kann zwischen dem Elektromagneten und dem Anker eine (nicht dargestellte) Dämpfung vorgesehen sein, beispielsweise Druckfedern oder ein geeignetes Dämpfungsmaterial. Die Betätigungseinrichtungen 29,30 können an Ort und Stelle auch an die Einbauverhältnisse angepaßt werden. So lassen sich die Hebel 31,32 beispielsweise leicht auf das erforderliche Maß kürzen. Ferner können die beiden Blattfedern 46 mit den Stellschrauben 48 unterschiedlich gebogen werden, so daß beispielsweise auch bei schräg eingebauten Dichtungseinrichtungen der Dichtungskörper 23 in seiner Dichtlage einwandfrei am Dichtungsstreifen 50 der Tür 10 anliegt.In order to reduce the impact noise of the armatures 44 when the electromagnets 45 are tightened, a damping (not shown) can be provided between the electromagnet and the armature, for example compression springs or a suitable damping material. The actuating devices 29, 30 can also be adapted on the spot to the installation conditions. For example, the levers 31, 32 can easily be shortened to the required size. Furthermore, the two leaf springs 46 can be bent differently with the set screws 48, so that, for example, even in the case of obliquely installed sealing devices, the sealing body 23 lies perfectly against the sealing strip 50 of the door 10 in its sealing position.
