- the seal of such a brush strip is naturally limited, the brush itself is expensive to manufacture.
- Such a sealing strip is known in particular from DE-A-3115129 (see FIG. 10), this sealing strip consisting of an essentially cross-sectionally shaped sealing body made of an elastomer, which encloses a cavity and has two strip-shaped extensions which correspond to one another Intervene in the undercuts of a holding profile.
- This sealing body lies sealingly against a roller door curtain, the sealing body being able to adapt to the contour of the rolling gate curtain.
- this previously known device has a further sealing rail with a sealing body which rests on the side of the roll armor opposite the seal body, so that a complete seal of the roll armor is achieved.
- the invention has for its object to provide a sealing strip of the type mentioned, with which a better sealing effect is achieved, which is cheaper to manufacture and which reliably prevents the lower door leaf armor end from overturning when the closing movement is initiated.

- the sealing strip according to the invention can be used in particular where the distance between the lintel and the roller shutter armor section which is guided past is not subject to excessive fluctuations.
- the sealing strip according to the invention is particularly well suited in connection with roller doors, the winding shaft mounting of which, depending on the winding diameter, ie the length of the roller door armor wound, can be displaced axially parallel to the lintel towards or away from the lintel.
- This through appropriate Mechanical gear connection produced displacement movement depending on the length of the roll-up door curtain wound in such a way that the roll-up door curtain rolling or rolling onto the roll is approximately the same distance from the lintel in every operating position.
- a preferred embodiment consists in the fact that the strip profile is intrinsically rigid in relation to the forces arising from the attack on the roller shutter curtain.
- the elastic resilience for the sealing abutment of the last profile on the outer surface of the door leaf armor and the required yield in the course of the undulating course of this door leaf surface in the direction of movement is achieved by a resilient zone of the plastic profile that is discussed in the longitudinal direction of the profile.

- the base region 6 moves away from the side plane of the fastening region 10 by approximately 45 ° in the unloaded state of the sealing strip, as can be seen from the drawing.
- a resilient zone 13 which is realized here by a notch, that is to say in the area of the zone 13 the wall thickness of the base area 6 and the fastening area 10 is reduced, so that there is an in Longitudinal profile extending "hinge" results, however, due to the plastic from which the sealing strip is made, resilient.
- This plastic can also be a synthetic rubber.
- the strip profile 2 pivots about the indentation or resilient zone 13 towards the lintel or springs back from it, so that in every movement position of the roller shutter curtain the contact surface 3 of the strip profile rests on the outer surface of the roller shutter curtain.
- the holding rail consists in the present case of a C-shaped sheet which includes a groove-shaped cavity 24, in such a way that the groove edge regions 27 delimiting the groove opening are directed towards one another.

Description
Die Erfindung bezieht sich auf eine Dichtungsleiste für Rolltore mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a sealing strip for roller doors with the features of the preamble of claim 1.
Der in Richtung der Schließlage hin jeweils von der Wickelwelle abgewickelte Teil des Rolltorpanzers wird beidseitig in Führungen insoweit dichtend aufgenommen; für die Abdichtung des Spaltbereiches zwischen dem Sturz der zu verschließenden Toröffnung und dem von dem Wickel abrollenden Abschnitt des Rolltorpanzers ist eine sich über diesen Spaltbereich hinweg erstreckende Dichtungsleiste vorgesehen, die nach dem Stand der Technik als Bürste ausgebildet ist, die mit ihren von dem Sturz abstehenden Borstenenden an der Torblatt-Außenfläche, deren in Bewegungsrichtung welligem Außenflächenverlauf folgend, angreifen. Die Dichtung einer solchen Bürstenleiste ist naturgemäß beschränkt, die Bürste selbst ist in der Herstellung aufwendig. Mit einer solchen Bürste kann man zwar verhältnismäßig große Differenzen in der Spaltbreite zwischen Sturz und Rolltorpanzer ausgleichen, die Borsten der Bürste müssen sich aber in die jeweilige Bewegungsrichtung des Rolltorpanzers - öffnen/schließen - umorientieren, was die Überwindung eines im Anfangsbereich der Umorientierung erheblich erhöhten Widerstandes der Borsten voraussetzt. Nach einem Überführungsvorgang des Rolltorpanzers in die Öffnungsstellung sind die Borsten der Bürste demnach nach oben gerichtet, wird nun ein Schließvorgang eingeleitet, so muß sich der noch sehr kurze, in Schließstellung nach unten gerichtete Endabschnitt des Rolltorpanzers unter der entsprechenden Drehrichtung des Wickels insoweit unter seinem Eigengewicht nach unten bewegen. Dabei muß jedoch der vorerwähnte Umorientierungswiderstand der Borsten überwunden werden, d.h. es wird eine Rückstaukraft auf diesen unteren Rolltorpanzerabschnitt ausgeübt, während die Wickelwelle den Abwickelvorgang einzuleiten sucht. Dadurch besteht die Gefahr, daß sich auf der Gegenabwickelrichtung der Wickelwelle ein Übergewicht mit der Folge bildet, daß das untere Ende des Rolltorpanzers ins Rauminnere hin über die Wickelwelle hinweggleitet und unter entsprechender schlagartiger Verlängerung nach unten fällt. Abgesehen davon, daß der Rolltorpanzer dabei nicht in den Führungen gehalten ist und eine erhebliche dynamische Beanspruchung in Bewegungsrichtung erhält, stellt ein solcher Vorgang eine Gefährdung für Personen und Güter dar, die sich im Bereich unter dem Wickel befinden.The part of the roller shutter curtain that is unwound in the direction of the closed position from the winding shaft is accommodated on both sides in guides; For the sealing of the gap area between the lintel of the door opening to be closed and the section of the roller shutter curtain that rolls off the wrap, a sealing strip extending over this gap area is provided, which, according to the prior art, is designed as a brush with its protruding from the lintel Grasp the bristle ends on the outer surface of the door leaf, following the outer surface that is wavy in the direction of movement. The seal of such a brush strip is naturally limited, the brush itself is expensive to manufacture. With such a brush, it is possible to compensate for relatively large differences in the gap width between the lintel and the roller shutter curtain, but the bristles of the brush have to reorient - open / close - in the respective direction of movement of the roller shutter curtain, which overcomes a resistance which is considerably increased in the initial area of the reorientation which requires bristles. After a transfer process of the roller shutter curtain into the open position, the bristles of the brush are therefore directed upwards, if a closing process is now initiated, the still very short end section of the roller shutter curtain that is directed downward in the closed position must be under its own weight under the corresponding direction of rotation of the winding move down. However, the aforementioned reorientation resistance of the bristles has to be overcome, ie a back pressure force is exerted on this lower roller door armor section while the winding shaft tries to initiate the unwinding process. As a result, there is a risk that an overweight forms in the counter-unwinding direction of the winding shaft, with the result that the lower end of the roller shutter curtain slides into the interior of the winding shaft and falls down with a corresponding sudden extension. Apart from the fact that the roller door curtain is not held in the guides and receives a considerable dynamic load in the direction of movement, such a process poses a danger to people and goods located in the area under the winding.
Eine derartige Dichtungsleiste ist insbesondere aus der DE-A-3115129 vorbekannt (vgl. Figur 10), wobei diese Dichtungsleiste aus einem im wesentlichen im Querschnitt oval ausgebildeten Dichtkörper aus einem Elastomer besteht, welcher einen Hohlraum umschließt und zwei leistenförmige Fortsätze hat, die in korrespondierende Hinterschneidungen eines Halteprofils eingreifen. Dieser Dichtkörper liegt dichtend an einem Rolltorpanzer an, wobei sich der Dichtkörper an die Kontur des Rolltorpanzers anpassen kann. Darüberhinaus weist diese vorbekannte Vorrichtung eine weitere Dichtungsschiene mit einem Dichtkörper auf, welcher auf der dem Dichtkörper gegenüberliegenden Seite des Rollpanzers anliegt, so daß eine vollständige Abdichtung des Rollpanzers erzielt wird.Such a sealing strip is known in particular from DE-A-3115129 (see FIG. 10), this sealing strip consisting of an essentially cross-sectionally shaped sealing body made of an elastomer, which encloses a cavity and has two strip-shaped extensions which correspond to one another Intervene in the undercuts of a holding profile. This sealing body lies sealingly against a roller door curtain, the sealing body being able to adapt to the contour of the rolling gate curtain. In addition, this previously known device has a further sealing rail with a sealing body which rests on the side of the roll armor opposite the seal body, so that a complete seal of the roll armor is achieved.
Der Erfindung liegt die Aufgabe zugrunde, eine Dichtungsleiste der eingangs genannten Art zur Verfügung zu stellen, mit der eine bessere Dichtwirkung erzielt wird, die billiger herzustellen ist und die ein rückstaubedingtes Überschlagen des unteren Torblattpanzerendes bei Einleitung der Schließbewegung sicher vermeidet.The invention has for its object to provide a sealing strip of the type mentioned, with which a better sealing effect is achieved, which is cheaper to manufacture and which reliably prevents the lower door leaf armor end from overturning when the closing movement is initiated.
Ausgehend von einer Dichtungsleiste mit den Merkmalen des Oberbegriffes des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst.Starting from a sealing strip with the features of the preamble of claim 1, this object is achieved according to the invention by its characterizing features.
Durch die erfindungsgemäße Ausbildung der Dichtungsleiste wird eine gegenüber der herkömmlichen Bürste wesentlich bessere Dichtung bei erheblich billigerem Aufbau der Dichtungsleiste erreicht. Das Leistenprofil bzw. die gesamte Dichtleiste kann ein- oder mehrteilig als Kunststoff-Extruderteil hergestellt sein, der dichtende Angriff der vorgewölbten Fläche des Leistenprofils an dem Rolltorpanzer bei kleinem Gleitwiderstand kann durch eine Beschichtung der vorgewölbten Fläche, besonders bevorzugt in Form einer Beflockung, die insbesondere aus einem Kautschukwerkstoff bestehen kann, ebenfalls in herstellungstechnisch einfacher Weise sichergestellt werden.The inventive design of the sealing strip is a much better seal compared to the conventional brush achieved with significantly cheaper construction of the sealing strip. The strip profile or the entire sealing strip can be made in one or more parts as a plastic extruder part, the sealing attack of the bulging surface of the strip profile on the roller door curtain with low sliding resistance can be achieved by coating the bulging surface, particularly preferably in the form of flocking, which in particular can consist of a rubber material, can also be ensured in a technically simple manner.
Die erfindungsgemäße Dichtungsleiste läßt sich insbesondere da anwenden, wo der Abstand zwischen dem Sturz und dem benachbart vorbeigeführten Rolltorpanzerabschnitt keinen zu großen Schwankungen unterliegt. Besonders gut eignet sich die erfindungsgemäße Dichtungsleiste im Zusammenhang mit Rolltoren, deren Wickelwellenlagerung in Abhängigkeit vom Wickeldurchmesser, d.h. der jeweils aufgewickelten Rolltorpanzerlänge, in achsparalleler Versetzung auf den Sturz zu bzw. von diesem fort zwangsgeführt versetzbar ist. Diese durch entsprechende mechanische Getriebeverbindung hergestellte Versetzbewegung in Abhängigkeit von der jeweils aufgewickelten Rolltorpanzerlänge ist derart getroffen, daß der vom Wickel abrollende oder auf diesen aufrollende Rolltorpanzer in jeder Betriebslage etwa denselben Abstand vom Sturz aufweist.The sealing strip according to the invention can be used in particular where the distance between the lintel and the roller shutter armor section which is guided past is not subject to excessive fluctuations. The sealing strip according to the invention is particularly well suited in connection with roller doors, the winding shaft mounting of which, depending on the winding diameter, ie the length of the roller door armor wound, can be displaced axially parallel to the lintel towards or away from the lintel. This through appropriate Mechanical gear connection produced displacement movement depending on the length of the roll-up door curtain wound in such a way that the roll-up door curtain rolling or rolling onto the roll is approximately the same distance from the lintel in every operating position.
Eine bevorzugte Ausführungsform besteht darin, daß das Leistenprofil hinsichtlich der durch den Angriff an dem Rolltorpanzer auftretenden Kräfte insoweit in sich unnachgiebig ausgebildet ist. Die elastische Nachgiebigkeit für die dichtende Anlage des Leistenprofils an der Torblattpanzeraußenfläche und das erforderliche Nachgeben im Verfolg des in Bewegungsrichtung welligen Verlaufes dieser Torblattfläche wird durch eine sich in Profillängsrichtung erstredende federelastische Zone des Kunststoff profils erreicht. Das Leistenprofil ist gegenüber einem anderen Bereich der Dichtungsleiste entsprechend auf den Sturz versetzbar gehalten, insbesondere dadurch, daß das Leistenprofil über eine sich in Profillängsrichtung erstreckende federelastische Zone mit einem Sturzbefestigungsbereich in Verbindung steht. Dabei kann die gesamte Dichtungsleiste ein einteiliges Kunststoffteil sein, das die Hohlprofilwandung des Leistenprofiles und den Sturzbefestigungsbereich umfaßt, wobei zwischen letzterem und dem Leistenprofil als federelastische Zone eine Einkerbung ausgebildet ist, die als federelastische Sollknickstelle dient. Der Sturzbefestigungsbereich dient dabei der Festlegung der Dichtungsleiste an dem Sturz, insbesondere dadurch, daß an dem Sturz eine Halteschiene mit einem nutförmigen Hohlraum angeordnet wird, in welchen eine an dem Sturz-Befestigungsbereich der Dichtungsleiste ausgeformte Einsteckleiste gegen Herausziehen gesichert einsetzbar ist.A preferred embodiment consists in the fact that the strip profile is intrinsically rigid in relation to the forces arising from the attack on the roller shutter curtain. The elastic resilience for the sealing abutment of the last profile on the outer surface of the door leaf armor and the required yield in the course of the undulating course of this door leaf surface in the direction of movement is achieved by a resilient zone of the plastic profile that is discussed in the longitudinal direction of the profile. The strip profile is held displaceable relative to another area of the sealing strip on the lintel, in particular in that the strip profile is connected to a lintel fastening region via a spring-elastic zone extending in the longitudinal direction of the profile. The entire sealing strip can be a one-piece plastic part, which comprises the hollow profile wall of the strip profile and the lintel fastening area, a notch being formed between the latter and the strip profile as a spring-elastic zone, which serves as a spring-elastic predetermined bending point. The lintel fastening area serves to fix the sealing strip to the lintel, in particular in that a holding rail with a groove-shaped cavity is arranged on the lintel, in which a molded-in plug strip on the lintel fastening region of the sealing strip is secured against being pulled out can be used.
Allternativ hierzu ist das Leistenprofil mit einer Profilwandung versehen, die hinsichtlich ihres Angriffes an dem Rolltorpanzer in Richtung auf den Sturz gesehen in sich elastisch nachgiebig verformbar ausgebildet ist. Die Leistenprofilwandung wird dann an einer an dem Sturz festzulegenden Halteleiste abgestützt. Dabei kann das Leistenprofil grundsätzlich mit einer im Querschnitt in sich geschlossenen Profilwandung versehen sein.As an alternative to this, the strip profile is provided with a profile wall which, as regards its attack on the roller shutter curtain in the direction of the lintel, is designed to be resiliently deformable in itself. The strip profile wall is then supported on a retaining strip to be fixed on the lintel. The strip profile can in principle be provided with a profile wall that is closed in cross-section.

- Figure 1
- a cross section through a sealing strip.
Das Ausführungsbeispiel gemäß Figur 1 zeigt eine insgesamt mit 1 bezeichnete Dichtungsleiste, die ein hinsichtlich der Beanspruchung durch die Anlage an dem nicht dargestellten Rolltorpanzer in sich steifes Leistenprofil 2 aus einer im Querschnitt in sich geschlossenen Hohlprofilwandung 5 aufweist. Die Hohlprofilwandung 5 weist einen von dem angedeuteten Sturz nach rechts abgewandte, dem nicht dargestellten Rolltorpanzer zugewandte, gegen diesen vorgewölbte Rolltorpanzer-Angriffsfläche 3 auf, die mit einer Beflockung 4 aus einem Kunstkautschuk als Gleitbelag versehen ist. An der der vorgewölbten Angriffsfläche 3 unter einem Winkel gegenüberliegenden Querschnittsseite des Profils 2 weist die Profilwandung einen ebenen Basisbereich 6 auf. Der von der Hohlprofilwandung 5 umschlossene Profilhohlraum 7 wird von einem Versteifungssteg 8 durchgriffen, der etwa im Mittelbereich des Basisbereiches 6 von diesem senkrecht abstehend zu der die Angriffsfläche 3 aufweisenden Vorwölbung 9 der Profilwandung 5 verläuft und in dieser mündet.The exemplary embodiment according to FIG. 1 shows a sealing strip, denoted overall by 1, which has a
Der Basisbereich 6 überragt zum Sturz hin gesehen um eine kleine Querschnittsstrecke die den Profilhohlraum 7 umgebende Hohlprofilwandung 5 und geht in einen Befestigungsbereich 10 der Dichtungsleiste 1 über, an deren dem Sturz zugewandten Seite eine Einsteckleiste 11 ausgeformt ist, die in eine Halteschiene 12 eingreift, welch letztere an dem Sturz in nicht näher bezeichneter Weise festgelegt ist. Der Basisbereich 6 entfernt sich aus der Seitenebene des Befestigungsbereiches 10 im unbelasteten Zustand der Dichtungsleiste etwa um 45°, wie dies aus der Zeichnung ersichtlich ist. Im Übergangsbereich zwischen dem Befestigungsbereich 10 und dem Basisbereich 6 befindet sich eine federelastische Zone 13, die hier durch eine Einkerbung verwirklicht ist, d.h. im Bereich der Zone 13 ist die Wandstärke des Basisbereiches 6 und des Befestigungsbereiches 10 herabgesetzt, so daß sich hier ein sich in Profillängsrichtung erstreckendes "Scharnier" ergibt, das jedoch aufgrund des Kunststoffes, aus dem die Dichtungsleiste besteht, federelastisch wirkt. Auch bei diesem Kunststoff kann es sich um einen Kunstkautschuk handeln. Unter Angriff an dem nicht dargestellten Rolltorpanzer verschwenkt das Leistenprofil 2 um die Einkerbung bzw. federelastische Zone 13 auf den Sturz zu bzw. federt von diesem zurück, so daß in jeder Bewegungsstellung des Rolltorpanzers die Anlagefläche 3 des Leistenprofils an der Außenfläche des Rolltorpanzers anliegt.The
Die Halteschiene besteht im vorliegenden Falle aus einem C-förmig gebogenen Blech, das einen nutförmigen Hohlraum 24 einschließt, und zwar derart, daß die die Nutöffnung begrenzenden Nutrandbereiche 27 aufeinander zu gerichtet sind. Die aus elastischem Kunststoff bestehende Einsteckleiste 11 zeigt einen pfeilförmigen Querschnitt und wird mit der Pfeilspitze 25 durch die Nutöffnung senkrecht zum Längsverlauf des nutförmigen Hohlraums 24 in diesen eingesetzt, bis die Pfeilschultern 26 die Ränder der Halteschiene 12 hintergreifen.The holding rail consists in the present case of a C-shaped sheet which includes a groove-
