Description

Die vorliegende Erfindung betrifft eine automatische Türdichtung mit wenigstens einem Haltemittel, wenigstens einem Scherenmechanismus mit zwei Scherenelementen und einer Dichtungsleiste, wobei das eine Scherenelement über ein erstes Lager mittelbar oder unmittelbar schwenkbar mit dem Haltemittel verbunden ist und das andere Scherenelement über ein zweites Lager schwenkbar mit der Dichtleiste verbunden ist, und die Scherenelemente über ein drittes Lager schwenkbar miteinander verbunden sind.The present invention relates to an automatic door seal with at least one holding means, at least one scissor mechanism with two scissor elements and a sealing strip, one scissor element being pivotably connected to the holding means directly or indirectly via a first bearing and the other scissor element being pivotably connected to the holding means via a second bearing Sealing strip is connected, and the scissor elements are pivotally connected to each other via a third bearing.

Aus dem Dokument EP 3 284 896 A1 , dem Dokument DE 60 2004 009 845 T2 und dem Dokument CH 465 830 sind Dichtungen mit Absenkmechanismen bekannt, die ein erstes und ein zweites Scherenelement aufweisen. Ein Vorteil dieser Dichtungen ist, dass mit ihnen eine Absenkung der Dichtleiste parallel gegenüber dem Haltemittel - meist handelt es sich dabei um das sogenannte Außenprofil oder Gehäuse - und ohne seitlichen Versatz der Dichtleiste möglich ist.From the document EP 3 284 896 A1 , the document DE 60 2004 009 845 T2 and the document CH 465 830 seals are known with lowering mechanisms having first and second scissor elements. One advantage of these seals is that they allow the sealing strip to be lowered parallel to the holding means—usually the so-called outer profile or housing—and without lateral displacement of the sealing strip.

Die bisher bekannten Dichtungen haben meist eine minimale Breite des Haltemittels von ca. 12 mm. Es gibt nur wenige Dichtungen, die eine geringere Breite, zum Beispiel von 8 mm haben. In vielen Anwendungsfällen sind aber Dichtungen erforderlich, die eine geringere Breite haben, zum Beispiel nur eine Breite von 8 mm. Es gibt einen Bedarf an verschiedenen Modellen von schmalen Dichtungen.The previously known seals usually have a minimum width of the holding means of about 12 mm. There are only a few seals that have a smaller width, for example 8 mm. In many applications, however, seals are required that have a smaller width, for example only a width of 8 mm. There is a need for different models of narrow seals.

Hier setzt die vorliegende Gruppe von Erfindungen an.This is where the present group of inventions comes in.

Den Erfindungen liegt die Aufgabe zugrunde, automatische Dichtungen, insbesondere solche mit Scherenelementen, vorzuschlagen, die eine geringe Breite haben.The object of the inventions is to propose automatic seals, in particular those with scissor elements, which have a small width.

Bei den Scherenelementen, insbesondere der Verbindung zwischen den beiden Scherenelementen im dritten Lager, besteht die Anforderung, dass ein seitliches Ausweichen oder Einknicken der Scherenelemente vermieden werden muss oder dass sich aufgrund von Momenten oder Kräften, die quer zur Längsrichtung der Dichtung wirken, die Verbindung des ersten und des zweiten Scherenelementes im dritten Lager löst.With the scissor elements, in particular the connection between the two scissor elements in the third bearing, there is a requirement that lateral deflection or buckling of the scissor elements must be avoided or that moments or forces acting transversely to the longitudinal direction of the seal cause the connection of the first and the second scissor element in the third camp solves.

Die der Erfindung zugrunde liegende Aufgabe wird erfindungsgemäß dadurch gelöst,

  • dass ein erstes der beiden Scherenelemente einen von einem Mittelteil des ersten Scherenelementes hervorstehenden Lagerzapfen und ein von dem Lagerzapfen auskragendes Riegelelement aufweist, wobei zwischen dem auskragenden Riegelelement und dem Mittelteil ein Abstand ist,
  • dass ein zweites der beiden Scherenelemente ein Loch mit einem ersten Abschnitt aufweist, der einen lichten Querschnitt hat, der dem Querschnitt des Lagerzapfens und des von dem Lagerzapfen auskragenden Riegelelementes entspricht, und
  • dass das dritte Lager den Lagerzapfen und das Loch umfasst.
The object on which the invention is based is achieved according to the invention in that
  • that a first of the two scissor elements has a bearing pin protruding from a central part of the first scissor element and a locking element projecting from the bearing pin, there being a distance between the projecting locking element and the central part,
  • that a second of the two scissor elements has a hole with a first portion which has a clear cross-section which corresponds to the cross-section of the bearing journal and of the locking element projecting from the bearing journal, and
  • that the third bearing comprises the bearing journal and the hole.

Der Lagerzapfen des ersten Scherenelementes wird zur Montage der Scherenelemente aneinander in das Loch in dem zweiten Scherenelement von einer ersten Seite eingesteckt. Das Ende des Lagerzapfens ragt dabei aus dem ersten Abschnitt des Loches heraus. Der Mittelteil des ersten der beiden Scherenelemente liegt vorzugsweise zwischen zwei Enden des ersten Scherenelementes. An einem dieser beiden Ende ist das erste oder das zweite Lager vorgesehen.The bearing pin of the first scissor element is inserted into the hole in the second scissor element from a first side in order to assemble the scissor elements to one another. The end of the bearing pin protrudes from the first section of the hole. The central part of the first of the two scissor elements is preferably located between two ends of the first scissor element. The first or the second bearing is provided at one of these two ends.

Das von dem Lagerzapfen im Wesentlichen quer zu diesem auskragende Riegelelement ist durch den ersten Abschnitt des Loches hindurchgeschoben und befindet sich nach der Montage nicht mehr in dem ersten Abschnitt. Dazu ist es zweckdienlich, wenn der erste Abschnitt des Loches im zweiten Scherenelement eine Tiefe hat, die dem Abstand zwischen dem auskragenden Riegelelement und dem Mittelteil des ersten Scherenelementes entspricht und dass der Lagerzapfen des ersten Scherenelementes den ersten Abschnitt des Loches durchgreift.The locking element projecting from the bearing journal substantially transversely thereto is pushed through the first section of the hole and is no longer located in the first section after assembly. It is expedient if the first section of the hole in the second scissor element has a depth that corresponds to the distance between the cantilevered locking element and the middle part of the first scissor element and that the bearing pin of the first scissor element reaches through the first section of the hole.

Das erste Scherenelement und das zweite Scherenelement sind so gestaltet, dass sie zueinander geschwenkt werden können. Das auskragende Riegelelement, wird durch ein Schwenken gegenüber dem ersten Abschnitt des Loches so bewegt, dass es nicht mehr durch den ersten Abschnitt zurückgezogen werden kann, so lange das erste und das zweite Scherenelement nicht die Stellung zu einander haben, die sie bei der Montage des Scherenmechanismus hatten. Das Loch in dem zweiten Scherenelement kann dazu einen zweiten Abschnitt haben, in dem ein Teil des Lagerzapfens und das auskragende Riegelelement schwenkbar angeordnet sind.The first scissor element and the second scissor element are designed in such a way that they can be pivoted towards one another. The projecting locking element is moved by pivoting in relation to the first section of the hole in such a way that it can no longer be pulled back through the first section as long as the first and second scissor elements are not in the position in relation to one another that they were in when the had scissor mechanism. For this purpose, the hole in the second scissor element can have a second section in which a part of the bearing pin and the cantilevered locking element are pivotably arranged.

Der zweite Abschnitt kann einen lichten Querschnitt haben, der dem Querschnitt des Lagerzapfens und des von dem Lagerzapfen auskragenden Riegelelementes zuzüglich einer Ausnehmung entspricht. Die Ausnehmung kann das auskragende Riegelelement aufnehmen, wenn der Lagerzapfen in dem Loch gedreht wird, also das erste und das zweite Scherenelement gegeneinander gedreht werden.The second section can have a clear cross section which corresponds to the cross section of the bearing journal and of the locking element projecting from the bearing journal plus a recess. The recess can accommodate the projecting locking element when the bearing pin is rotated in the hole, that is to say the first and the second scissor element are rotated in relation to one another.

Es ist von Vorteil, wenn der Lagerzapfen und das auskragende Riegelelement zwischen einer ersten Endstellung und einer zweiten Endstellung geschwenkt werden können. In der ersten Endstellung kann zum Beispiel das auskragende Riegelelement durch den ersten Abschnitt des Loches hindurch geschoben werden, um die Scherenelemente aneinander zu montieren. Diese Endstellungen können auf verschiedene Weise festgelegt sein. So ist es zum Beispiel möglich, dass der zweite Abschnitt des Loches in dem zweiten Scherenelement zumindest eine erste Begrenzungsfläche und eine zweite Begrenzungsfläche aufweist, wobei die erste Begrenzungsfläche einen Anschlag für das auskragende Riegelelement in der ersten Endstellung bildet und die zweite Begrenzungsfläche einen Anschlag für das auskragende Riegelelement in der zweiten Endstellung bildet. Insbesondere die zweite Begrenzungsfläche kann eine Begrenzungsfläche der Ausnehmung sein.It is advantageous if the bearing pin and the projecting locking element can be pivoted between a first end position and a second end position. In the first end position, for example, the cantilevered locking element through the first Section of the hole are pushed through to assemble the scissor elements together. These end positions can be defined in various ways. For example, it is possible for the second section of the hole in the second scissor element to have at least a first boundary surface and a second boundary surface, with the first boundary surface forming a stop for the projecting locking element in the first end position and the second boundary surface forming a stop for the cantilevered locking element forms in the second end position. In particular, the second boundary surface can be a boundary surface of the recess.

Die in den Figuren dargestellte erfindungsgemäße automatisch absenkbare Türdichtung weist ein Haltemittel 2 auf, das ein Gehäuse 20 aufweist. Dieses kann mittels Befestigungswinkeln 1 zum Beispiel in einer Nut einer Tür befestigt werden. Mit anderen Befestigungsmitteln ist auch eine Befestigung an einer Außenseite einer Tür möglich. Das Gehäuse 20 hat ein sich in einer Längsrichtung erstreckendes gleichförmiges Profil. Vorzugsweise ist das Gehäuse ein Aluminiumstrangpressprofil.The automatically lowerable door seal according to the invention shown in the figures has a holding means 2 which has a housing 20 . This can be fastened in a groove of a door, for example, by means of fastening brackets 1 . Fastening to an outside of a door is also possible with other fastening means. The housing 20 has itself in one Longitudinally uniform profile. The housing is preferably an aluminum extruded profile.

In dem Gehäuse 20 sind Führungsteile 21, 22 und ein Stützelement 23 befestigt. Die Führungsteile führen eine Stange 40, die zusammen mit im Beispiel zwei Scherenmechanismen einen Absenkmechanismus bilden. Die Scherenmechanismen weisen je ein erstes Scherenelement 41 und je ein zweites Scherenelement 42 auf.In the housing 20 guide parts 21, 22 and a support member 23 are fixed. The guide parts guide a rod 40 which, together with two scissor mechanisms in the example, form a lowering mechanism. The scissor mechanisms each have a first scissor element 41 and a second scissor element 42 .

Mit dem Absenkmechanismus kann eine Dichtleiste 5 aus einer angehobenen Position in eine abgesenkte Position bewegt werden. Die Dichtleiste 5 ist zweiteilig und umfasst eine Innenschiene 50 und ein Dichtungsprofil 51, welche sich dicht an einer Oberfläche, zum Beispiel dem Fußboden, anlegen kann.With the lowering mechanism, a sealing strip 5 can be moved from a raised position to a lowered position. The sealing strip 5 is in two parts and includes an inner rail 50 and a sealing profile 51, which can be applied tightly to a surface, for example the floor.

Der Absenkmechanismus ist mit einem Auslöser 3 gekoppelt, über den eine für die Betätigung der Dichtung notwendige Kraft in den Absenkmechanismus eingebracht werden kann.The lowering mechanism is coupled to a trigger 3, via which a force required to actuate the seal can be introduced into the lowering mechanism.

Der Auslöser 3 der erfindungsgemäßen Dichtung ist zweiteilig aufgebaut. Er weist einen Kopf 31 und ein Kopplungselement 32 auf. Die Relativposition von Kopf 31 und Kopplungselement 32 zu einander kann verändert werden. Dadurch ist es möglich, die Länge des Auslösers in Längsrichtung einzustellen. Eine Längeneinstellung eines Auslösers kann genutzt werden, um den Hub einer Dichtung einzustellen.The trigger 3 of the seal according to the invention is constructed in two parts. It has a head 31 and a coupling element 32 . The relative position of head 31 and coupling element 32 to each other can be changed. This makes it possible to adjust the length of the trigger in the longitudinal direction. A length adjustment of an actuator can be used to adjust the stroke of a seal.

Bei der Variante ist der Auslöser 3 ebenfalls zweiteilig gestaltet Er weist einen Kopf 31 und ein Kopplungselement 32 auf. Die Relativposition von Kopf 31 und Kopplungselement 32 zu einander kann verändert werden. Dadurch ist es möglich, die Länge des Auslösers in Längsrichtung einzustellen. Eine Längeneinstellung eines Auslösers kann genutzt werden, um den Hub einer Dichtung einzustellen.In the variant, the trigger 3 is also designed in two parts. It has a head 31 and a coupling element 32 . The relative position of head 31 and coupling element 32 to each other can be changed. This makes it possible to adjust the length of the trigger in the longitudinal direction. A length setting of a trigger can be used to set the stroke of a seal.

Der Kopf 31 des Auslösers 3 weist ebenfalls eine Anschlagsfläche 310 auf, über die eine äußere Kraft in den Auslöser 3 bzw. den Absenkmechanismus 4 eingeleitet werden kann. Der Kopf 31 hat einen Tragkörper 311, an dem die Anschlagsfläche 310 vorgesehen ist. An einer Oberseite des Tragkörpers 311 ist eine Führungsstruktur 312 vorgesehen. Diese wird durch zwei seitlich auskragende Stege gebildet, die in komplementären Führungsstrukturen des Außenprofils verschiebbar angeordnet sind. Der Kopf weist eine Aufnahme 314 auf, die ein Innengewinde hat.The head 31 of the trigger 3 also has a stop surface 310 via which an external force can be introduced into the trigger 3 or the lowering mechanism 4 . The head 31 has a support body 311 on which the stop surface 310 is provided. A guide structure 312 is provided on an upper side of the support body 311 . This is formed by two laterally overhanging webs that are slidably arranged in complementary guide structures of the outer profile. The head has a receptacle 314 which is internally threaded.

Das Kopplungselement 32 des Auslösers 3 weist einen Tragkörper, nämlich den Tragkörper 320 auf. Dieser Tragkörper 320 trägt Führungsstrukturen 321, die genau so gestaltet sind wie die Führungsstruktur 312 des Kopfes 31. Das Kopplungselement 32 weist auf einer dem Kopf 31 zugewandten Seite eine Gewindestange 326 auf. Diese Gewindestange ist seitlich abgeflacht und glatt. Lediglich eine Oberseite und eine Unterseite der Stange sind abgerundet und weisen Abschnitte des Gewindegangs eines herkömmlichen Gewindes auf. Die Gewindestange 326 trägt ein unvollständiges Gewinde, das in die Aufnahme 314 eingeschraubt ist.The coupling element 32 of the trigger 3 has a supporting body, namely the supporting body 320 . This support body 320 carries guide structures 321, which are designed exactly like the guide structure 312 of the head 31. The coupling element 32 has a threaded rod 326 on a side facing the head 31. This threaded rod is flattened and smooth on the side. Only a top and a bottom of the rod are rounded and have portions of the thread pitch of a conventional thread. The threaded rod 326 carries an incomplete thread which is screwed into the socket 314 .

An dem der Gewindestange 326 entgegengesetzten Ende des Tragkörpers 320 ist eine Verbindungsstruktur 325 vorgesehen, die der Verbindung des Auslösers mit dem Absenkmechanismus 4 dient.A connection structure 325 is provided on the end of the support body 320 opposite the threaded rod 326 and serves to connect the trigger to the lowering mechanism 4 .

Bei den Führungsteilen 21, 22 und dem Stützelement 23 handelt es sich um Formteile, die eine an das Gehäuse 20 angepasste Außenkontur haben, so dass die Führungsteile 21, 22 und das Stützelement 23 in das Gehäuse 20 eingeschoben und dort befestigt werden können. Das Gehäuse 20 weist dazu nach innen ragenden Stege 200 auf, die von komplementären Verbindungstrukturen der Führungsteile 21, 22 und des Stützelements 23 ebenso hintergriffen werden wie von den Führungsstrukturen 312, 321 des Kopfes 3.The guide parts 21, 22 and the support element 23 are molded parts which have an outer contour adapted to the housing 20, so that the guide parts 21, 22 and the support element 23 are inserted into the housing 20 and fastened there can become. For this purpose, the housing 20 has inwardly projecting webs 200, which are engaged behind by complementary connecting structures of the guide parts 21, 22 and the support element 23 as well as by the guide structures 312, 321 of the head 3.

Erste Führungsteile 21 und zweite Führungsteile 22 der Führungsteile 21, 22 weisen einen Kanal auf, durch den die Stange 40 hindurchgeführt ist. Diese Stange ist mehrteilig und weist mehrere hintereinander liegende Abschnitte auf, die miteinander verbunden sind. Einer dieser Abschnitte ist ein Verschiebeteil 401, welches eine besondere Funktion für den Absenkmechanismus 4 hat und noch näher beschrieben wird. Ein anderer Abschnitt der Stange 40 ist mit dem Auslöser verbunden. Dieser Abschnitt weist eine Verbindungsstruktur 49 auf, die mit der Verbindungsstruktur 325 des Auslösers 3 gekoppelt ist.First guide parts 21 and second guide parts 22 of the guide parts 21, 22 have a channel through which the rod 40 is passed. This rod is in several parts and has several sections lying one behind the other, which are connected to one another. One of these sections is a sliding part 401, which has a special function for the lowering mechanism 4 and will be described in more detail later. Another portion of the rod 40 is connected to the trigger. This section has a connection structure 49 coupled to the connection structure 325 of the trigger 3 .

Das Stützteil 23 ist am Ende der Stange 40 vorgesehen. Es hat eine Aufnahme, in die das Ende der Stange 40 eingeführt ist. In der Aufnahme ist auf einem Dorn 230 eine Rückstellfeder 44 des Absenkmechanismus angeordnet. Diese Rückstellfeder 44 bewirkt nach einer Entlastung des Auslösers 3 einen Übergang der Dichtung vom betätigten in den nicht betätigten Zustand. Die Rückstellfeder drückt dazu auf das Ende der Stange 40, welches in der Aufnahme des dritten Führungsteils 22 angeordnet ist. Im dargestellten Beispiel ist die Rückstellfeder eine Schraubendruckfeder. Es könnte sich aber auch um eine Feder handeln, die ein Wellen-, Dreiecks-, Sägezahnprofil oder ähnlich gebogenes Profil hat.The support part 23 is provided at the end of the rod 40 . It has a seat into which the end of the rod 40 is inserted. A return spring 44 of the lowering mechanism is arranged on a mandrel 230 in the receptacle. After release of the trigger 3, this return spring 44 causes the seal to transition from the actuated to the non-actuated state. For this purpose, the restoring spring presses on the end of the rod 40 which is arranged in the receptacle of the third guide part 22 . In the example shown, the return spring is a helical compression spring. However, it could also be a spring that has a wave, triangular, sawtooth or similarly curved profile.

Die Stange 40 ist mit den Scherenmechanismen gekoppelt, die identisch ausgebildet sind und die das erste Scherenelement 41 und das zweite Scherenelement 42 umfassen. Das erste Scherenelement 41 ist über ein erstes Lager L1 schwenkbar an dem zweiten Führungsteil 22 gelagert. Das zweite Scherenelement 42 ist in einem zweiten Lager L2 schwenkbar mit einem Innenprofil 50 der Dichtleiste 5 verbunden. Das erste Lager L1 und das zweite Lager L2 haben Schwenkachsen, die in einer Ebene senkrecht zur Längsrichtung der Dichtung liegen. In einem dritten Lager L3 sind das erste Scherenelement 41 und das zweite Scherenelement 42 zueinander schwenkbar aneinandergelagert. Das erste, zweite und dritte Lager L1, L2, L3 sind Drehlager.The rod 40 is coupled to the scissors mechanisms, which are identical and which comprise the first scissors element 41 and the second scissors element 42 . The first scissors element 41 is pivotable on the second via a first bearing L1 Guide part 22 stored. The second scissor element 42 is pivotably connected to an inner profile 50 of the sealing strip 5 in a second bearing L2. The first bearing L1 and the second bearing L2 have pivot axes lying in a plane perpendicular to the longitudinal direction of the seal. In a third bearing L3, the first scissor element 41 and the second scissor element 42 are mounted on one another such that they can be pivoted relative to one another. The first, second and third bearings L1, L2, L3 are pivot bearings.

Das erste Scherenelement 41 ist am im ersten Lager L1 gelagerten Ende gegabelt. Die durch die Gabelung entstandenen Gabelbeine 413 weisen nach außen ragende Lagerzapfen 410 auf, die in Ausnehmungen 220 in dem zweiten Führungsteil 22 gelagert sind. Die Lagerzapfen 410 und die Ausnehmungen 220 bilden das erste Lager L1. Die beiden Gabelbeine 413 haben einen Abstand, der so gewählt ist, dass die Stange 40 zwischen den beiden Gabelbeinen hindurchgeführt werden kann.The first scissors member 41 is bifurcated at the end supported in the first bearing L1. The fork legs 413 created by the fork have outwardly protruding bearing pins 410 which are mounted in recesses 220 in the second guide part 22 . The trunnions 410 and the recesses 220 form the first bearing L1. The two fork legs 413 are spaced apart so that the rod 40 can be passed between the two fork legs.

Das erste Scherenelement 41 hat an einem Mittelteil 415 einen weiteren Lagerzapfen 411, der zusammen mit einem Loch 421, das in dem zweiten Scherenelement 42 vorgesehen ist und in das der Lagerzapfen 411 eingesteckt ist, das dritte Lager L3 bildet. Das Loch 421 des zweiten Scherenelements weist einen ersten Abschnitt mit einem im Querschnitt kreisförmigen Bereich und einen mit diesem verbundenen rechteckigen, an den kreisförmigen Bereich ansetzenden rechteckigen Bereich 4210 auf. Von dem Ende des Lagerzapfens 411 des ersten Scherenelementes 41 kragt ein auskragendes Riegelelement 4110 aus, das den gleichen Querschnitt hat, wie der rechteckige Bereich 4210. Der Lagerzapfen 411 kann nur dann in das Loch 421 eingesteckt oder aus dem Loch herausgezogen werden, wenn das Riegelelement 4110 und der rechteckige Bereich 4210 in Überdeckung sind. Vorzugsweise sind das Riegelelement 4110 und der rechteckige Bereich 4210 in einer Stellung der Scherenelemente 41, 42 in Überdeckung, die nicht der Stellung entspricht, in der die Dichtleiste 5 abgesenkt ist, so dass die Scherenelemente 41, 42 sich im abgesenkten Zustand der Dichtungsleiste nicht voneinander lösen können.The first scissors member 41 has at a central portion 415 another pivot 411 which forms the third bearing L3 together with a hole 421 provided in the second scissors member 42 and into which the pivot 411 is inserted. The hole 421 of the second scissor element has a first section with a circular section and a rectangular section 4210 connected thereto and continuing to the circular section. From the end of the pivot 411 of the first scissor element 41 protrudes a cantilevered locking element 4110, which has the same cross-section as the rectangular area 4210. The pivot 411 can only be inserted into the hole 421 or pulled out of the hole when the locking element 4110 and the rectangular area 4210 are in register. Preferably, the locking element 4110 and the rectangular area 4210 overlaps in a position of the scissor elements 41, 42 which does not correspond to the position in which the sealing strip 5 is lowered, so that the scissor elements 41, 42 cannot separate from one another when the sealing strip is in the lowered state.

Das Loch 421 in dem zweiten Scherenelement hat einen zweiten Abschnitt, in dem das auskragende Riegelelement 4110 anordnet ist. Dieser zweite Abschnitt des Lochs 421 hat den gleichen lichten Querschnitt wie der erste Abschnitt mit dem Unterschied, dass auch noch eine Ausnehmung 4211 zu diesem zweiten Abschnitt gehört. Das Riegelelement 4110 ist in dieser Ausnehmung 4211 angeordnet, wenn die Dichtungsleiste abgesenkt ist. Der zweite Abschnitt des Lochs 421 hat eine erste Begrenzungsfläche 4212 und eine zweite Begrenzungsfläche 4213. Diese legen Endstellungen fest, die das Riegelelement 4110 in dem zweiten Abschnitt des Lochs 421 bei einem Schwenken der Scherenelemente 41, 42 zueinander erreichen können. Durch die zweite Begrenzungsfläche 4213 wird der maximale Hub der Dichtungsleiste begrenzt.The hole 421 in the second scissor member has a second portion in which the cantilever latch member 4110 is located. This second section of the hole 421 has the same clear cross-section as the first section, with the difference that a recess 4211 also belongs to this second section. The locking element 4110 is arranged in this recess 4211 when the sealing strip is lowered. The second section of the hole 421 has a first boundary surface 4212 and a second boundary surface 4213. These define end positions which the locking element 4110 can reach in the second section of the hole 421 when the scissor elements 41, 42 pivot towards one another. The maximum stroke of the sealing strip is limited by the second delimiting surface 4213 .

Das erste Scherenelement hat ein vom ersten Lager L1 betrachtet jenseits des dritten Lagers L3 liegendes Ende 414. Zwischen diesem Ende 413 und dem dritten Lager L3 erstreckt sich ein Abschnitt 412 des ersten Scherenelementes. Das Ende 414 wird in einem Kanal der Innenschiene 50 geführt, die durch Seitenwände 501, 502 und einen von der Seitenwand 502 in Richtung zur ersten Seitenwand 501 ragenden Steg 503 begrenzt wird. Der Kanal bildet ein Linearlager, in dem das Ende 414 geführt ist. Der Abschnitt 412 weist auf seiner der Stange 40 zugewandten Seite einen Schlitz auf, der ungefähr so breit ist wie die Stange 40. Im nicht betätigten Zustand der Dichtung greift die Stange 40 in den Schlitz ein. Die Lage des ersten Scherenelementes wird durch das Eingreifen der Stange 50 in den Schlitz und insbesondere durch die Führung in dem Kanal in der Querrichtung gehalten.The first scissor element has an end 414 lying beyond the third bearing L3, viewed from the first bearing L1. A section 412 of the first scissor element extends between this end 413 and the third bearing L3. The end 414 is guided in a channel of the inner rail 50, which is delimited by side walls 501, 502 and a web 503 projecting from the side wall 502 in the direction of the first side wall 501. The channel forms a linear bearing in which the end 414 is guided. The section 412 has a slot on its side facing the rod 40 which is approximately as wide as the rod 40. In the non-actuated state of the seal, the rod 40 engages in the slot. The position of the first scissor element is determined by the engagement of the rod 50 in the Slot and held in particular by the guide in the channel in the transverse direction.

Das zweite Lager L2, in dem das zweite Scherenelement 42 und die Innenschiene 50 aneinander gelagert sind, wird durch einen Lagerzapfen 420 und einen Kanal gebildet, der durch den Boden 500, die Seitenwände 501, 502 und den von der Seitenwand 502 in Richtung zur ersten Seitenwand 501 ragenden Steg 503 gebildet ist. Der Steg 503 wird von dem Lagerzapfen 420 hintergriffen.The second bearing L2, in which the second scissor element 42 and the inner rail 50 are mounted together, is formed by a bearing journal 420 and a channel which extends through the floor 500, the side walls 501, 502 and from the side wall 502 towards the first Side wall 501 projecting web 503 is formed. The bearing pin 420 engages behind the web 503 .

Das zweite Scherenelement 42 hat ein vom zweiten Lager L2 betrachtet jenseits des dritten Lagers L3 liegendes Ende 423. Dieses Ende 423 ist über ein viertes Lager L4 mit der Stange 40 verbunden. Es handelt sich bei dem vierten Lager L4 um ein Lager mit zwei Freiheitsgraden, die eine Drehung und eine Verschiebung des Endes des zweite Scherenelementes 42 gegenüber der Stange 40 zulassen.The second scissor element 42 has an end 423 lying beyond the third bearing L3 as viewed from the second bearing L2. This end 423 is connected to the rod 40 via a fourth bearing L4. The fourth bearing L4 is a bearing with two degrees of freedom, which allows rotation and translation of the end of the second scissor element 42 with respect to the rod 40 .

In der Querrichtung ist das zweite Scherenelement weder im zweiten Lager L2 noch im vierten Lager L4 verschiebbar. Dadurch kann das zweite Scherenelement 42 nicht oder allenfalls wenig in der Querrichtung verschoben werden.In the transverse direction, the second scissor element is not displaceable in either the second bearing L2 or the fourth bearing L4. As a result, the second scissor element 42 cannot be displaced in the transverse direction, if at all.

Im Normalfall ist das Ende des zweiten Scherenelementes 42 an einer Verschiebung gegenüber der Stange 40 durch eine Überlastfeder 43 gehindert, die das Ende 423 des zweiten Scherenelementes 42 an einen Rand einer Ausnehmung 4011 des Verschiebeteils 401 zieht und zwar an einen Rand der Ausnehmung 4011 auf der dem Auslöser 3 abgewandten Seite. Die Feder 43 ist dazu an dem Ende 423 des zweiten Scherenelementes 42 eingehängt und an einem Haken 4010 der Stange 40 an dem dem Auslöser 3 abgewandten Ende der Ausnehmung 4011 eingehängt. Nur in besonderen Fällen lösen sich das Ende 423 des zweiten Scherenelementes und der Rand der Ausnehmung 4011 gegen den Zug der Feder 43 voneinander.Normally, the end of the second scissor element 42 is prevented from shifting relative to the rod 40 by an overload spring 43, which pulls the end 423 of the second scissor element 42 to an edge of a recess 4011 in the displacement part 401, specifically to an edge of the recess 4011 on the the side facing away from the trigger 3. For this purpose, the spring 43 is suspended at the end 423 of the second scissor element 42 and suspended from a hook 4010 of the rod 40 at the end of the recess 4011 facing away from the trigger 3 . Only in special cases solve the end 423 of the second scissor element and the edge of the recess 4011 against the tension of the spring 43 from each other.

Wird nun durch eine Betätigung des Auslösers 3 die Stange 40 verschoben, verschiebt sich das Ende 423 des zweiten Scherenelementes 42 gegenüber dem über das zweite Führungsteil 22 fest mit dem Gehäuse 20 verbundenen ersten Lager L1. Dabei wird das zweite Lager L2, das das zweite Scherenelement 42 mit dem Innenprofil 50 verbindet, aufgrund der Verbindung des ersten und des zweiten Scherenelementes 41, 42 im dritten Lager L3 linear nach unten abgesenkt. Die Dichtleiste 5 wird dadurch quer zur Längsrichtung der Dichtung abgesenkt und gegen den Boden gedrückt, so dass das Dichtungsprofil 51 an dem Boden anliegt. Dadurch, dass zwei identische Scherenmechanismen vorgesehen sind und diese durch die Stange 40 synchron betätigt werden, wird die Dichtleiste 5 parallel zum Gehäuse 2 abgesenkt.If the rod 40 is now displaced by actuating the trigger 3, the end 423 of the second scissor element 42 is displaced in relation to the first bearing L1, which is firmly connected to the housing 20 via the second guide part 22. The second bearing L2, which connects the second scissor element 42 to the inner profile 50, is lowered linearly downwards in the third bearing L3 due to the connection of the first and the second scissor element 41, 42. The sealing strip 5 is thereby lowered transversely to the longitudinal direction of the seal and pressed against the floor, so that the sealing profile 51 bears against the floor. Due to the fact that two identical scissor mechanisms are provided and these are actuated synchronously by the rod 40, the sealing strip 5 is lowered parallel to the housing 2.

Liegt nun die Dichtleiste 5 auf dem Boden auf, kann sie nicht weiter nach unten bewegt werden. Auch das zweite Lager L2 kann dann nicht weiter nach unten bewegt werden, wodurch das Ende 423 des zweiten Scherenelementes an einer weiteren Bewegung mit der Stange 40 gehindert ist. Wird dann aber weiter über den Auslöser 3 ein Druck auf die Stange 40 ausgeübt und übersteigt dieser Druck die Kraft der Überlastfeder 43, löst sich das Ende 423 des zweiten Scherenelementes 42 von dem Rand der Ausnehmung 4011 und das Ende 423 bewegt sich in der Ausnehmung 4011, da die Stange 40 gegenüber dem Ende 423 verschoben wird. Durch dieses Zusammenwirken der Ausnehmung 4011, des Endes 423 des zweiten Scherenelementes 42 und der Überlastfeder 43 wird eine Überlastung des Absenkmechanismus 4 verhindert, die zu Schäden an der Dichtung führen könnte.If the sealing strip 5 is now on the ground, it cannot be moved further down. The second bearing L2 can then also not be moved any further downwards, as a result of which the end 423 of the second scissor element is prevented from moving further with the rod 40. If, however, further pressure is then exerted on the rod 40 via the trigger 3 and this pressure exceeds the force of the overload spring 43, the end 423 of the second scissor element 42 detaches from the edge of the recess 4011 and the end 423 moves in the recess 4011 , since the rod 40 is displaced with respect to the end 423. This interaction of the recess 4011, the end 423 of the second scissor element 42 and the overload spring 43 prevents the lowering mechanism 4 from being overloaded, which could lead to damage to the seal.

An dem zweiten Ende 423 des zweiten Scherenelementes sind kreissegmentartige Strukturen vorgesehen. Diese liegen an der Innenseite eines Stegs 201 des Gehäuses 20 an oder sind mit nur geringem Abstand zur Innenseite dieses Stegs 201 angeordnet und bewegen sich bei einer Betätigung der Dichtung, ggf. mit Abstand, entlang der Innenseite des Gehäuses 20.Structures in the manner of segments of a circle are provided at the second end 423 of the second scissor element. These rest on the inside of a web 201 of the housing 20 or are arranged at only a small distance from the inside of this web 201 and move when the seal is actuated, possibly at a distance, along the inside of the housing 20.
