Abstract

The seal contains a flat lower magnetic bar (14) in a threshold (10) and a profiled upper magnetic bar (20) which is received in the manner of a piston vertically movably by a rectangular channel profile (25). The two magnetic bars have one pole on the door-opening side and the other pole on the door-closing side, but in an opposite arrangement, so that, during the closing of the door, the upper magnetic bar is drawn downwards by the attraction and sits down, whereas, during the commencing opening movement, it is repelled upwards. In the upper position, it is held against a sheet-steel strip (28) by means of the rearward magnetic attraction. The forwardly directed magnetic force predominates over that directed rearwards. The seal can be used irrespective of the particular position, that is to say both on the floor and on the side (door frame). <IMAGE>

Description

Die Erfindung bezieht sich auf eine magnetische Türdichtung mit den Merkmalen nach dem Oberbegriff des Hauptanspruchs.The invention relates to a magnetic door seal with the features according to the preamble of the main claim.

Magnetische Türdichtungen dieser Art haben zwei einander zugeordnete Magnetstäbe, einer davon im Türblatt eingebaut, der andere ortsfest eingebaut, derart, daß bei geschlossenem Türblatt einer davon durch die gegenseitige magnetische Anziehung wie ein Schieber herausgezogen wird, auf dem anderen Magnetstab aufsitzt, so daß der Spalt geschlossen wird. Bei Beginn der Öffnungsbewegung wird der verschiebbare Magnetstab durch abstoßende Magnetkräfte in die ihn aufnehmende Führung zurückgestoßen.Magnetic door seals of this type have two mutually assigned magnetic bars, one installed in the door leaf, the other installed in a stationary manner, such that when the door leaf is closed, one of them is pulled out like a slide by the mutual magnetic attraction, sits on the other magnetic bar, so that the gap is closed. At the start of the opening movement, the displaceable magnetic rod is pushed back into the guide receiving it by repulsive magnetic forces.

Bei einer bekannten Magnettürdichtung der vorgenannten Art (DE-PS 37 08 176) ist als lotrecht verschiebbares Dichtungselement ein bodenseitig von einem Halteprofil aufgenommene mehrfach alternierender Magnetstab vorgesehen, der bei Schließen der Tür von einem fest an der Türblattunterseite angebrachten gleichfalls mehrfach alternierenden Magnetstab angezogen wird, so daß dadurch der Türspalt geschlossen wird. Beim Öffnen der Tür ergibt sich durch eine deckungsgleiche Lage gleichmagnetisierter Pole eine Abstoßung und damit eine Öffnung des unteren Türspaltes. Der bewegliche Magnetstab bleibt durch sein Eigengewicht in der Halterung. Eine Rückführung des beweglichen Magnetstabs in die Halterung durch mechanische oder magnetische Kräfte ist dabei nicht vorgesehen. Die bekannte magnetische Türdichtungen ist somit nur zur Abdichtung eines bodenseitigen Türspaltes anwendbar, bei Einbau des beweglichen Magnetstabes im Bodenbereich.In a known magnetic door seal of the aforementioned type (DE-PS 37 08 176), a vertically displaceable sealing element is a multi-alternating magnetic rod provided on the bottom side by a holding profile, which is attracted by a likewise alternating magnetic rod fixedly attached to the underside of the door leaf when the door is closed, so that the door gap is closed. When the door is opened, a congruent position of the same magnetized poles results in repulsion and thus an opening of the lower door gap. The moveable magnetic rod remains in the holder due to its own weight. A return of the movable magnetic rod into the holder by mechanical or magnetic forces is not provided. The known magnetic door seals can therefore only be used for sealing a floor-side door gap when the movable magnetic bar is installed in the floor area.

Der Erfindung liegt die Aufgabe zugrunde, eine magnetische Türdichtung der genannten Art so auszubilden, daß der verschiebbare Magnetstab auch beim Öffnen der Tür unabhängig von seinem Eigengewicht durch Magnetkräfte in seine Führung zurückgebracht wird.The invention has for its object to design a magnetic door seal of the type mentioned so that the displaceable magnetic rod is brought back into its guide regardless of its own weight by magnetic forces even when the door is opened.

Außer dem bereits erwähnten Stand der Technik ist (FR-PS 1.526.154) eine magnetische Türdichtung für einen unteren Türspalt bekannt, bei der in einer Nut des Türblatts mehrere Zylinder aus einem elastischen magnetischen Werkstoff um eine horizontale Achse schwenkbar exzentrisch gelagert sind. Im Bereich des größeren Durchmessers ist jeder Zylinder magnetisiert. Beim Schließen der Tür wird der magnetische Bereich von einen bodenseitigen Magnetstreifen angezogen, so daß er dort aufsitzt, während beim Öffnen der Tür der magnetische Bereich des jeweiligen Zylinders durch einen seitlich an der Nutwand angebrachten Magnetstreifen angezogen wird, so daß der Bereich des größeren Durchmessers abgehoben wird, bei einer Schwenkung des Zylinders um etwa 90°. Das in diesem Stand der Technik offenbarte Prinzip einer magnetischen Rückführung ist jedoch bei einer magnetischen Türdichtung der Eingangs beschriebenen Art nicht anwendbar.In addition to the already mentioned prior art (FR-PS 1.526.154), a magnetic door seal for a lower door gap is known, in which several cylinders made of an elastic magnetic material are pivotally eccentrically mounted in a groove of the door leaf. In the area of the larger diameter, each cylinder is magnetized. When the door is closed, the magnetic area is attracted by a magnetic strip on the bottom, so that it sits there, while when the door is opened, the magnetic area of the respective cylinder is attracted by a magnetic strip attached to the side of the groove wall, so that the larger diameter area is lifted off when the cylinder swivels about 90 °. However, the principle of magnetic feedback disclosed in this prior art cannot be applied to a magnetic door seal of the type described in the introduction.

Die bestehende Aufgabe wird durch eine magnetische Türdichtung mit den Merkmalen nach dem Hauptanspruch gelöst. Die Unteransprüche haben weitere konstruktive Ausgestaltungen und verschiedene Anwendungsmöglichkeiten des Lösungsprinzips zum Inhalt.The existing task is solved by a magnetic door seal with the features according to the main claim. The subclaims have further constructive configurations and various possible uses of the solution principle.

Wenn bei einer solchen Türdichtung der verschiebbare Magnetstab vorderseitig von dem nicht verschiebbaren Stab abgestoßen wird, dann wird rückseitig ein entgegengesetzt gerichtetes Magnetfeld wirksam, das eine Anziehung an einem in der Halterung gelagerten Stahlblechstreifens zur Folge hat, so daß dadurch der verschiebbare Magnetstab ständig und unabhängig von seinem Eigengewicht in seinem Führungsprofil gehalten wird. Wird jedoch der Türflügel wieder geschlossen, und gelangen die beiden einander zugeordneten Magnetstäbe wieder in Deckung, so überwiegt das vordere Magnetfeld das rückseitige und der verschiebbare Stab wird herausgezogen, so daß die beiden aufeinander sitzenden Magnetstäbe die Abdichtung des Türspaltes hervorrufen.With such a door seal, the displaceable magnetic rod is repelled from the front by the non-displaceable rod, then an oppositely directed magnetic field becomes effective on the rear, which results in an attraction on a steel strip which is mounted in the holder, so that the displaceable magnetic rod is thereby constantly and independently of its own weight in its management profile is held. However, if the door leaf is closed again, and the two associated magnetic bars come back into cover, the front magnetic field outweighs the rear and the displaceable bar is pulled out, so that the two magnetic bars sitting one on top of the other cause the door gap to be sealed.

Eine Türdichtung nach der Erfindung kann, da unabhängig von ihrer räumlichen Lage, sowohl zur Abdichtung der bodenseitigen Türspalte, als auch der seitlichen und des oberen Türspaltes, also des Spaltes gegenüber der Türzarge eingesetzt werden. Dabei kann das Rinnenprofil mit dem verschiebbaren Magnetstab sowohl ortsfest also bodenseitig oder in der Türzarge als auch im Türblatt eingesetzt werden, bei einem entsprechenden Einbau des unverschiebbaren Stabes. Das Rinnenprofil zur Aufnahme des verschiebbaren Stabes wird nach einer bevorzugten Ausführungsform der Erfindung derartig profiliert, daß der verschiebbare Stab nach Art eines Kolbens durch seitliche angeformte Leisten geführt wird, wobei zwischen den hinteren Leisten und der Profildecke ein niedriger Raum entsteht, in den der Stahlblechstreifen eingeschoben werden kann. Eine magnetische Türdichtung nach der Erfindung ist für eine Ringsum-Dichtung geeignet.A door seal according to the invention can be used, irrespective of its spatial position, both for sealing the bottom door gap, and for the side and top door gap, that is to say the gap with respect to the door frame. The channel profile with the displaceable magnetic bar can be used both in a fixed position, that is on the floor or in the door frame and in the door leaf, if the immovable bar is installed accordingly. According to a preferred embodiment of the invention, the channel profile for receiving the displaceable rod is profiled in such a way that the displaceable rod is guided in the manner of a piston through molded-on strips on the side, a low space being created between the rear strips and the profile ceiling, into which the sheet steel strip is inserted can be. A magnetic door seal according to the invention is suitable for an all-round seal.

Zunächst wird auf die Ausführungsform nach Fig. 1 und 2 Bezug genommen.First, reference is made to the embodiment according to FIGS. 1 and 2.

Das bewegliche Dichtungselement, welches die Abdichtung bewirkt, ist ein profilierter Magnetstab 20 aus einem nicht harten, also etwas weichen magnetisierten Werkstoff. Der Magnetstab erstreckt sich über die gesamte Länge des Türblattes. Sein Querschnitt ist im Prinzip rechteckig mit einem breiteren Vorderteil 21, einem schmaleren Mittelteil 22 und einem wiederum schmaleren hinteren Teil 23. Zwischen diesem hinteren Teil und dem Mittelteil sind seitliche Leisten 24 angeformt, von gleicher Breite wie das Vorderteil 21. Die linke Hälfte, zur Türöffnungsseite 2 gerichtet, ist der Südpolbereich 20a, die rechte Hälfte der Nordpolbereich 20b. Das magnetische Kraftfeld erstreckt sich sowohl nach vorne, also nach unten, sowie auch nach hinten, in diesem Fall nach oben, wobei das nach vorne gerichtete Magnetfeld größer ist.The movable sealing element, which effects the sealing, is a profiled magnetic rod 20 made of a non-hard, that is to say somewhat soft, magnetized material. The magnetic bar extends over the entire length of the door leaf. Its cross section is in principle rectangular with a wider front part 21, a narrower middle part 22 and a again narrower rear part 23. Between this rear part and the middle part, lateral strips 24 are formed, of the same width as the front part 21. The left half, for Facing door opening side 2, the south pole area 20a, the right half is the north pole area 20b. The magnetic force field extends both forwards, downwards, and also backwards, in this case upwards, the forward magnetic field being larger.

Der Magnetstab 20 wird von einem im Türblatt eingenuteten Rinnenprofil 25 derart aufgenommen, daß er ein Stück nach unten verschiebbar ist. Bei dieser Bewegung ist der Magnetstab durch seine Leisten 24 und durch den Vorderteil 21 an den Seitenwänden des Rinnenprofils nach Art eines Kolbens geführt. In dem Raum zwischen den hinteren Leisten 26 und der Bodenfläche des Rinnenprofils ist ein Stahlblechstreifen 28 eingeschoben. An diesem liegt das hintere Teil 23 des Magnetstabes, wie dargestellt, magnetisch an, so daß er sich nahezu vollständig im Rinnenprofil befindet, wobei die frontale Fläche des Vorderteils 21 im wesentlichen bündig mit der unteren Türblattfläche liegt. Das rechteckige unten offene Rinnenprofil 25 ist in der Nähe des Türanschlags 4 im Türblatt 1 eingenutet.The magnetic rod 20 is received by a groove profile 25 grooved in the door leaf in such a way that it can be displaced a little downwards. During this movement, the magnetic rod is like one through its strips 24 and through the front part 21 on the side walls of the channel profile Pistons led. A sheet steel strip 28 is inserted into the space between the rear strips 26 and the bottom surface of the channel profile. At this, the rear part 23 of the magnetic bar, as shown, is magnetically in contact, so that it is located almost completely in the channel profile, the front surface of the front part 21 being essentially flush with the lower door leaf surface. The rectangular channel profile 25, which is open at the bottom, is grooved near the door stop 4 in the door leaf 1.

Dem Magnetstab 20 ist ein flacher Magnetstab 14, bodenseitig, zugeordnet, der eine umgekehrte Polarisierung hat, d. h., daß der Südpolbereich 14b an der Anschlagseite, der Nordpolbereich 14a an der Öffnungsseite des Türflügels liegt. Der flache Magnetstab 14 wird von einem Schwellenprofil 10 aufgenommen, das bodenseitig aufsitzt, wobei der rechteckige Mittelteil des Schwellenprofils, in dem der Magnetstab 14 eingeklipst ist, sich durch seitliche gewölbte Flansche 12 fortsetzt, die gleichfalls bis zum Fußboden reichen. Das Schwellenprofil ist durch Schrauben am Fußboden befestigt. An einer Seite des Rechteckraumes des Schwellenprofils ist ein Absatz 11 geformt, wo der Magnetstab 14 aufsitzt, wobei dieser auf der gegenüberliegenden Seite zum Höhenausgleich einen vorspringenden Absatz hat. Durch diese asymmetrische Anordnung ist gewährleistet, daß der Magnetstab in der richtigen Polanordnung in das Schwellenprofil eingesetzt werden kann. In der eingesetzten Lage wird er durch die Ränder an der Schwelle etwas vorspringend gehalten.A flat magnetic rod 14, on the bottom side, is assigned to the magnetic rod 20 and has a reverse polarization, i. that is, the south pole area 14b on the stop side, the north pole area 14a on the opening side of the door leaf. The flat magnetic rod 14 is received by a threshold profile 10, which is seated on the floor side, the rectangular central part of the threshold profile, in which the magnetic rod 14 is clipped in, being continued by lateral curved flanges 12, which also extend to the floor. The threshold profile is attached to the floor by screws. A shoulder 11 is formed on one side of the rectangular space of the threshold profile, where the magnetic rod 14 is seated, and on the opposite side has a projecting shoulder for height compensation. This asymmetrical arrangement ensures that the magnetic rod can be inserted into the threshold profile in the correct pole arrangement. In the inserted position, it is held slightly projecting by the edges on the threshold.

Wenn die Tür geschlossen ist und die Stellung nach Fig. 2 erreicht hat, dann stehen sich die entgegengesetzten Pole des bodenseitigen Magnetstabes 14 und des türblattseitigen Magnetstabes 20 einander gegenüber und entwickeln eine derart große Anziehungskraft, so daß die nach hinten gerichtete Anziehungskraft überwunden und der Magnetstab 20 herausgezogen wird, bis zum Aufsitzen auf dem bodenseitigen Magnetstab 14, eine Stellung die Fig. 2 zeigt. Der untere Türspalt ist dabei abgedichtet. Wird aus der Stellung nach Fig. 2 heraus die Tür geöffnet, dann gelangt der Nordpol des oberen Magnetstabes 20 über den Nordpol des unteren Magnetstabes, so daß jener zurückgestoßen wird in das Rinnenprofil, wo er beim weiteren Öffnen durch die nach hinten gerichtete magnetische Anziehungskraft am Stahlblechstreifen gehalten wird.When the door is closed and has reached the position shown in FIG. 2, then the opposite poles of the bottom-side magnetic rod 14 and the door-leaf-side magnetic rod 20 face each other and develop such a great force of attraction that the rearward force of attraction is overcome and the magnet rod 20 is pulled out until it sits on the floor Magnetic rod 14, a position shown in FIG. 2. The lower door gap is sealed. If the door is opened from the position shown in FIG. 2, then the north pole of the upper magnetic rod 20 passes over the north pole of the lower magnetic rod, so that the latter is pushed back into the channel profile, where it opens when opened further by the magnetic attraction force directed backwards Sheet steel strip is held.

Die magnetische Türdichtung nach Fig. 3 ist zur Abdichtung eines Türspaltes zwischen Türblatt und Türzarge eingesetzt. Dabei ist das gleiche Rinnenprofil 25 mit dem gleichen profilierten Magnetstab 20 wie bei der Ausführung nach Fig. 1 und 2 in eine Türzarge 30 eingebaut. Dem verschiebbaren Magnetstab 20 ist ein flacher Magnetstab 33 zugeordnet, der an der Leibungsfläche 32 des Türblattfalzes befestigt ist. Die Bewegungsabläufe sind im wesentlichen die gleichen wie bei einer bodenseitigen Türdichtung gemäß Fig. 1 und 2.The magnetic door seal according to FIG. 3 is used to seal a door gap between the door leaf and door frame. The same channel profile 25 with the same profiled magnetic rod 20 as in the embodiment according to FIGS. 1 and 2 is installed in a door frame 30. A flat magnetic rod 33 is assigned to the displaceable magnetic rod 20 and is attached to the reveal surface 32 of the door leaf fold. The movement sequences are essentially the same as in the case of a door seal on the bottom according to FIGS. 1 and 2.
