Definitions

  • the invention relates to a roller door with the features of the preamble of claim 1.
  • Roller shutters of this type are known - DE-U-82 06 622 - whereby it is difficult to keep thin and light door leaf curtains in the closed state taut and tight even under the influence of wind.
  • the object of the invention is to provide a roller door of the type in question, the curtain of which is kept as tight as possible in the closed position, and in addition a structure which is as space-saving as possible and simple to assemble should be provided.
  • the roller shutter shown has no weight compensation spring. Such is often provided inside the winding roller 2, which complicates maintenance. There are other solutions with external counterbalance springs.
  • the door according to the invention can also be provided with such a weight compensation spring device.
  • the mass of the curtain is assumed, i.e. the door leaf weight is relatively low, so that a weight balance seems unnecessary.
  • Weight differences between the rolled and the rolled curtain, which act as torque on the axis of the winding roller are - like the acceleration forces - absorbed by the drive, in particular designed as an electric motor, which is common to the winding roller 2 and the conical cable drums 4 Wave 3 attacks.
  • the taper of the cable drum 4 is chosen so that when the curtain 1 rolls into the door leaf closing position and thus in diameter decreasing curtain roll 11, the traction cable 5 is wound, but in the direction of a decreasing diameter in accordance with the decreasing curtain diameter.
  • the tension spring 6 acting on the tension cable 6 is therefore not exposed to any change in length due to the curtain movement itself, so it remains during operation in the same more or less pretensioned working position, in which the curtain is kept so tight that it has no distortions in its lateral guides running.
  • the spring is therefore initially only used to compensate for differences in dimensions, such as can occur in particular due to temperature changes.
  • the two conical cable drums 4 are fixed on the drive shaft 3 with the aid of the ratchet wheel and pawl, the ratchet wheel being rotatably mounted on the shaft 3 and the pawl on an end face of the respective conical cable drum 4.
  • the pawl works in the direction of engagement so that in the course of a rotary movement of the cable drum 4 around the shaft 3 and against the latching direction of the pawl, the pull cable 5 is wound onto the cable drum.
  • the conical rope drum has the following special feature, which is particularly, if not exclusively, important in connection with the thin, low-weight curtains of roller doors in question: Shortly before the door leaf arrives in the closed position, ie approximately a distance which corresponds to the length of a winding, in the present example approximately 70 cm, the traction cable 5 arrives at the point with the smallest drum diameter in the course of the spiral cable receiving groove of the drum. The rope is thus wound in the course of the closing process of the curtain from one end, for example, seen from the outside of the curtain, with a large diameter of the cable drum in a position with a decreasing diameter, following the guidance of the correspondingly shaped groove in the axial direction of the roll.
  • the traction cable 5 is wound onto a partial area of the cable drum 4, which increases again with regard to the drum diameter in the course of the winding process and also continues the guide groove in this area.
  • the cable drum corresponding to the above tension conditions thus has a double-conical shape, the location of the smallest diameter being located off-center between the end faces of the drum, each with an increased diameter.
  • a cable drum shape is not only important for very thin curtains, it can in principle be used for a special tensile load on a roller shutter door in the closed position.
  • a special fixing of the curtain 1 on the winding roller 2 is not necessary because the curtain is only unwound from the winding roller 2 up to about one and a quarter turns. It is therefore sufficient that the end of the curtain 1 close to the roller on the surface of the winding roller to fix in the appropriate place, for example to glue. For normal operation, the remaining wrap angle of the curtain on the roller is large enough to ensure a non-slip attack between the curtain and the roller, even when viewed from the closed position of the curtain.
  • the relatively thin curtain in question is wound around a roller, the drive shaft 3 of which is rigidly mounted with respect to its spatial position or spacing from the lintel of the opening to be closed. There is therefore no positively controlled displacement movement of the drive shaft 3 depending on the winding condition of the winding roller 2, as can be provided for thicker curtains or lamella door leaves in order to be able to introduce the draining curtain from the curtain winding into the lateral guides as smoothly and as freely as possible.
  • the curtain 1 is steered into its closing plane or its lateral guides with the aid of a support roller 14, the special structure of which is described below:
  • the support roller 14 is provided with a tubular structure 15, in particular a textile, such as fabric, felt or the like, which is pushed onto the outer surface of a tubular fixed support 16 and is rotatably held thereon.
  • the hose-like structure 15 can extend over the entire width of the curtain or can be configured and arranged in several parts to partial width regions of the curtain.
  • the curtain engages on the outer surface of this tubular sliding textile or the like. The movement of the curtain entrains the hose or structure and rotates it relative to the carrier. Measures to achieve particularly good sliding properties can be taken between the tubular structure and the carrier; this can be achieved by appropriate pairing of materials or by the arrangement of a corresponding one low-friction intermediate layer can be achieved.
  • Such a support or guide roller 14 can be provided between the lintel and the curtain 1, but it can also act on the surface of the curtain 1 facing the interior of the room or can additionally be arranged in this direction, so that a pair of such guide rollers or hose-like structure lead the curtain 1 between them.
  • the guiding properties of such a support roller 14 are so good that even large deflections of the curtain course seen in the direction of movement can be mastered effortlessly and with little friction and with wear.
  • the carrier 16 for receiving the tubular structure 15 is fixed and accordingly has only a partial area on which the textile structure must be supported.
  • the cross-sectional dimension of the carrier can accordingly be limited to such a curved wing area. So it does not have to be a tube, a support with a C-shaped cross-section or a similar design can also be used.
  • the radius of curvature of the wing area is determined primarily by the deformability of the curtain.
  • the tubular structure is more flexible than the curtain, so it can undergo greater curvatures, so that one can work with correspondingly narrower "support rollers", the supports of which are significantly narrower than twice the diameter of the radius of curvature and the tube guided on the wing in the end. and run-up area of the wing passes through a bend that is narrower than this.
  • a special feature of this support roller 14 with the rotating hose is that the moving mass is very small because the hose only has to have a small wall thickness and is the only part of this support device that rotates. Bearing, balancing and, in so far, also abrasion problems, which would be comparable to those of rolling elements which are rotatable about relatively thin axes, do not occur.
  • Such a radially projecting flange can be formed, for example, by a so-called collar bushing which has a cylindrical part, onto which the hose is pushed and which is provided with a radially projecting part, which forms the actual end face or sliding surface. Furthermore, one can make the carrier spherical in the wing area or also continuously or imitate such crowning by providing some webs on the carrier towards the axial center with increasing diameter and the like and more. The measure to be taken largely depends on the consistency of the hose material; a rigid hose can guide itself, while a hose that tends to bulge or compress in the axial direction may have to be seized separately in the end region (collar bushing).
  • the traction ropes have to be wound onto the conical rope drums 4 following the course of the groove.

  • the fastening of the traction cable or the drum-side traction cable end to the cable drum can be carried out in a simple manner from an assembly point of view, similar to that described in connection with the holding of the curtain on the winding roller 2. If you make sure that one turn of the pull rope remains on the rope drum, the friction is sufficient to hold the rope on the drum without any special definition. For example, you can simply put the end of the rope through a radially directed hole in the beginning of the spiral groove, which makes assembly very easy.

Description

Die Erfindung bezieht sich auf ein Rolltor mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a roller door with the features of the preamble of claim 1.

Rolltore dieser Art sind bekannt - DE-U-82 06 622 -, wobei es schwierig ist, insbesondere dünne und leichte Torblatt-Behänge im Schließzustand auch unter Windeinfluß straff und dicht zu halten.Roller shutters of this type are known - DE-U-82 06 622 - whereby it is difficult to keep thin and light door leaf curtains in the closed state taut and tight even under the influence of wind.

Der Erfindung liegt die Aufgabe zugrunde, ein Rolltor der in Rede stehenden Art zur Verfügung zu stellen, dessen Behang in der Schließlage möglichst gestrafft gehalten ist, wobei zusätzlich ein möglichst raumsparender und in der Montage einfacher Aufbau gegeben sein soll.The object of the invention is to provide a roller door of the type in question, the curtain of which is kept as tight as possible in the closed position, and in addition a structure which is as space-saving as possible and simple to assemble should be provided.

Ausgehend von einem Rolltor mit den Merkmalen des Oberbegriffes des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst.Starting from a roller door with the features of the preamble of claim 1, this object is achieved according to the invention by its characterizing features.

Durch die doppelkonusförmige Ausbildung der Seiltrommel derart, daß die für den Wickelauf- bzw. -abbau erforderliche Konizität gegen Ende des Schließvorganges umgekehrt wird, erreicht man eine erhöhte Zugbelastung auf den Behang, so daß dieser die angestrebte straffe und windstabile dichte Lage einnimmt. Die dafür erforderliche Nachgiebigkeit kann aus dem Behang stammen, in bevorzugter Ausführung wird jedoch eine Feder eingesetzt, die in weiterhin bevorzugter Ausführung mit einem Flaschenzug zusammenarbeitet. Damit erreicht man zusätzlich einen geringeren Trommeldurchmesser, wodurch der Raumbedarf des Tores verringert wird.Due to the double-conical design of the cable drum in such a way that the conicity required for winding up and down is reversed towards the end of the closing process, an increased tensile load is achieved on the curtain, so that it assumes the desired tight and wind-stable tight position. The flexibility required for this can come from the curtain, but in a preferred embodiment a spring is used, which in a further preferred embodiment works with a pulley. This also achieves a smaller drum diameter, which means that space is required of the gate is reduced.

Diese und weitere bevorzugte Ausführungen der Erfindung ergeben sich aus den Unteransprüchen.These and other preferred embodiments of the invention result from the subclaims.

Die Erfindung wird nachstehend anhand des in der Zeichnung wiedergegebenen Ausführungsbeispieles näher erläutert, wobei

zeigen. Das Torblatt besteht aus einem sogenannten Behang 1 , hier in Form einer Folie, die etwa 4 mm dick sein kann und auf eine Wickelwalze 2 auf- und abgewickelt wird, die in diesem Beispiel einen Durchmesser von ca. 220 mm aufweisen soll. Koaxial zu beiden Stirnseiten der Wickelwalze 2 sind auf derselben tragenden Welle 3 konische Seiltrommeln 4 angeordnet, die nach folgender Maßgabe im Durchmesser kleiner ausgebildet sind als die Wickelwalze 2 bzw. der auf dieser angeordnete Wickel 11 des Behanges 1: Der Radius zwischen der Rotationsachse der Welle 3 und dem Auf- bzw. Ablaufbereich eines Zugseiles 5, das auf der Seiltrommel 4 auf- und abwickelbar in einer spiraligen Rille geführt ist, ist halb so groß wie der Radius zwischen der Rotationsachse und dem Auf- bzw. Ablaufbereich des Behanges 1 auf den Behangwickel 11 der Wickelwalze 2. Diese Hälftigkeit erreicht man dadurch, daß das von der jeweiligen Seiltrommel 4 kommende Zugseil 5 an der Lagerkausche 12 einer losen Rolle 7 festgelegt ist, um welche ein Spannseil 6 herumläuft, das einen Endes an dem jeweiligen Seitenbereich der Unterkante bzw. Abschlußprofilschiene 13 des Behanges 1 befestigt ist, dann um eine feste Rolle 8 läuft, die im unteren Bodenbereich der Torzarge 9 ortsfest gehalten ist, darauf um die lose Rolle 7 herumgeführt ist und mit dem anderen Ende an das eine Anschlußende einer Schraubenzugfeder 10 anschließt, deren anderes Anschlußende wiederum im Bodenbereich der Zarge verankert ist. Aufgrund des Flaschenzugs aus loser Rolle 7 und fester Rolle 8 ergibt sich das oben angesprochene Durchmesserverhältnis von 1 : 2. Die Schraubenzugfeder könnte auch zwischen die lose Rolle und das Zugseil 5 eingeschaltet sein, würde dann aber die doppelte Last aufzunehmen haben.The invention is explained below with reference to the embodiment shown in the drawing, wherein

demonstrate. The door leaf consists of a so-called curtain 1, here in the form of a film, which can be approximately 4 mm thick and is wound up and unwound on a winding roller 2, which in this example should have a diameter of approximately 220 mm. Coaxial to both end faces of the winding roller 2, conical cable drums 4 are arranged on the same supporting shaft 3, which are smaller in diameter than the winding roller 2 or the winding 11 of the curtain 1 arranged thereon: the radius between the axis of rotation of the shaft 3 and the up and down area of a traction rope 5, which can be wound up and unwound in a spiral groove on the cable drum 4, is half the size of the radius between the axis of rotation and the up and down area of the curtain 1 on the Curtain roll 11 of the winding roller 2. This Halfness is achieved in that the pull rope 5 coming from the respective rope drum 4 is fixed to the bearing thimble 12 of a loose roller 7, around which a tension rope 6 runs, which one end fastens to the respective side region of the lower edge or end profile rail 13 of the curtain 1 is, then runs around a fixed roller 8, which is held stationary in the lower bottom region of the door frame 9, is guided around it around the loose roller 7 and connects with the other end to the one end of a helical tension spring 10, the other end of which in turn is in the bottom region of the Frame is anchored. Due to the pulley system from loose roller 7 and fixed roller 8, the above-mentioned diameter ratio of 1: 2 results. The coil tension spring could also be switched on between the loose roller and the pull rope 5, but would then have to take up twice the load.

Das wiedergegebene Rolltor weist keine Gewichtsausgleichsfeder auf. Eine solche ist vielfach im Inneren der Wickelwalze 2 vorgesehen, was die Wartung erschwert. Es gibt auch andere Lösungen mit externen Gewichtsausgleichsfedern. Grundsätzlich kann auch das erfindungsgemäße Tor mit einer solchen Gewichtsausgleichs-Federeinrichtung versehen sein. Hier ist jedoch vorausgesetztermaßen die Masse des Behanges, d.h. das Torblattgewicht verhältnismäßig gering, so daß ein Gewichtsausgleich entbehrlich erscheint. Gewichtsunterschiede zwischen dem aufgerollten und dem abgerollten Behang, die als Drehmoment auf die Achse der Wickelwalze wirken, werden - wie auch die Beschleunigungskräfte - durch den Antrieb, insbesondere ausgebildet als Elektromotor, aufgenommen, der an der für die Wickelwalze 2 und die konischen Seiltrommeln 4 gemeinsamen Welle 3 angreift.The roller shutter shown has no weight compensation spring. Such is often provided inside the winding roller 2, which complicates maintenance. There are other solutions with external counterbalance springs. In principle, the door according to the invention can also be provided with such a weight compensation spring device. However, here the mass of the curtain is assumed, i.e. the door leaf weight is relatively low, so that a weight balance seems unnecessary. Weight differences between the rolled and the rolled curtain, which act as torque on the axis of the winding roller, are - like the acceleration forces - absorbed by the drive, in particular designed as an electric motor, which is common to the winding roller 2 and the conical cable drums 4 Wave 3 attacks.

Während der Behang 1 an der dem Sturz der zu verschließenden Gebäudeöffnung zugewandten Seite an dem Behangwickel 11 auf- und abrollt, ist dies hinsichtlich des Zugseiles 5 umgekehrt. Die Konizität der Seiltrommel 4 ist dabei so gewählt, daß bei Abrollen des Behanges 1 in die Torblattschließlage und damit im Durchmesser abnehmendem Behangwickel 11 das Zugseil 5 aufgewickelt wird, jedoch in Richtung eines kleiner werdenden Durchmessers nach Maßgabe des kleiner werdenden Behangwickeldurchmesser. Die an dem Spannseil 6 angreifende Schraubenzugfeder 10 wird somit aufgrund der Behangbewegung selbst keiner Längenänderung ausgesetzt, sie bleibt während des Betriebes also insoweit in derselben mehr oder weniger vorgespannten Arbeitslage, in welcher der Behang so weit straff gehalten ist, daß er in seinen seitlichen Führungen verwerfungsfrei läuft. Die Feder dient von daher zunächst nur dem Ausgleich von Abmessungsunterschieden, wie sie insbesondere durch Temperaturänderungen auftreten können.While the curtain 1 rolls up and down on the curtain winding 11 on the side facing the lintel of the building opening to be closed, this is reversed with regard to the pull cable 5. The taper of the cable drum 4 is chosen so that when the curtain 1 rolls into the door leaf closing position and thus in diameter decreasing curtain roll 11, the traction cable 5 is wound, but in the direction of a decreasing diameter in accordance with the decreasing curtain diameter. The tension spring 6 acting on the tension cable 6 is therefore not exposed to any change in length due to the curtain movement itself, so it remains during operation in the same more or less pretensioned working position, in which the curtain is kept so tight that it has no distortions in its lateral guides running. The spring is therefore initially only used to compensate for differences in dimensions, such as can occur in particular due to temperature changes.

Die beiden konischen Seiltrommeln 4 sind an der Antriebswelle 3 mit Hilfe von Klinkenrad und Klinke festgelegt, wobei sich das Klinkenrad verdrehfest an der Welle 3 und die Klinke an einer Stirnseite der jeweiligen konischen Seiltrommel 4 schwenkbar gelagert befinden. Die Klinke arbeitet in Eingriffsrichtung so, daß im Zuge einer Drehbewegung der Seiltrommel 4 um die Welle 3 herum und gegen die Rastrichtung der Klinke das Zugseil 5 auf die Seiltrommel aufgewickelt wird. Damit kann man das Zugseil 5 gegen die Kraft der im unteren Zargenbereich über den Flaschenzug 7, 8 angeordneten Schraubenzugfeder 10 auf die Seiltrommel 4 aufwickeln. Hat das Zugseil 5 die gewünschte Spannung, so beendet man diese Relativ-Drehbewegung zwischen Welle 3 und Seiltrommel 4, so daß die federbelastete Klinke unter entsprechender Rückdrehung von der Schraubenzugfeder 10 aus und über das Zugseil 5 auf die konische Seiltrommel 4 übertragen in das Klinkenrad eingreift. In dieser Stellung ist die Seiltrommel 4 hinsichtlich der herrschenden Zugrichtungen verdrehfest mit der Rotationsachse 3 verbunden.The two conical cable drums 4 are fixed on the drive shaft 3 with the aid of the ratchet wheel and pawl, the ratchet wheel being rotatably mounted on the shaft 3 and the pawl on an end face of the respective conical cable drum 4. The pawl works in the direction of engagement so that in the course of a rotary movement of the cable drum 4 around the shaft 3 and against the latching direction of the pawl, the pull cable 5 is wound onto the cable drum. Thus, one can wind up the pull rope 5 against the force of the coil tension spring 10 arranged in the lower frame area via the pulley 7, 8 on the rope drum 4. If the pull cable 5 has the desired tension, this relative rotary movement between the shaft 3 and the cable drum 4 is ended, so that the spring-loaded pawl engages in the ratchet wheel 4 with a corresponding backward rotation from the helical tension spring 10 and transmitted via the pull cable 5 to the conical cable drum 4 . In this position, the cable drum 4 is non-rotatably connected to the axis of rotation 3 with respect to the prevailing pull directions.

Im vorliegenden Fall weist die konische Seiltrommel folgende Besonderheit auf, die insbesondere, wenn auch nicht ausschließlich, im Zusammenhang mit den hier in Rede stehenden dünnen, gewichtsarmen Behängen von Rolltoren von Bedeutung ist: Kurz bevor das Torblatt in die Schließstellung gelangt, d.h. etwa einer Strecke, die der Länge eines Wickels entspricht, im vorliegenden Beispiel etwa 70 cm, gelangt das Zugseil 5 im Verfolg der spiraligen Seilaufnahmerille der Trommel an die Stelle mit dem geringsten Trommeldurchmesser. Das Seil wird also im Zuge des Schließvorganges des Behanges von der einen, beispielsweise vom Behang aus gesehen außen liegenden Stirnseite mit großem Durchmesser der Seiltrommel in einer Lage mit kleiner werdendem Durchmesser der Führung der entsprechend ausgeformten Rille in Achsialrichtung der Rolle folgend aufgewickelt. Über die letzte Abwickelstrecke des Behanges 1 in die Schließlage hinein wird das Zugseil 5 auf einen Teilbereich der Seiltrommel 4 aufgewickelt, der im Zuge des Aufwickelvorganges hinsichtlich des Trommeldurchmessers wieder ansteigt und auch in diesem Bereich die Führungsrille fortsetzt. Durch die Vergrößerung des Seiltrommeldurchmessers bei Verfahren des Behanges 1 in die Schließlage hinein wird erreicht, daß sich das Seil zu verkürzen sucht und damit eine steigende Belastung auf die Schraubenzugfeder 10 ausübt. Dadurch wird eine entsprechende Zugkraft auf den Behang 1 aufgebracht, so daß dieser in der Schließstellung straff zwischen den Seilen und der Wickelwalze 2 gespannt ist, derart, daß der Behang trotz dünner Ausführung auch unter stärkeren Windbelastungen nur wenig verwölbt.In the present case, the conical rope drum has the following special feature, which is particularly, if not exclusively, important in connection with the thin, low-weight curtains of roller doors in question: Shortly before the door leaf arrives in the closed position, ie approximately a distance which corresponds to the length of a winding, in the present example approximately 70 cm, the traction cable 5 arrives at the point with the smallest drum diameter in the course of the spiral cable receiving groove of the drum. The rope is thus wound in the course of the closing process of the curtain from one end, for example, seen from the outside of the curtain, with a large diameter of the cable drum in a position with a decreasing diameter, following the guidance of the correspondingly shaped groove in the axial direction of the roll. Over the last unwinding section of the curtain 1 into the closed position, the traction cable 5 is wound onto a partial area of the cable drum 4, which increases again with regard to the drum diameter in the course of the winding process and also continues the guide groove in this area. By increasing the diameter of the cable drum when moving the curtain 1 into the closed position it is achieved that the cable tries to shorten and thus exerts an increasing load on the helical tension spring 10. As a result, a corresponding tensile force is applied to the curtain 1, so that in the closed position it is stretched taut between the cables and the winding roller 2, such that the curtain is only slightly warped even under strong wind loads, despite the thin design.

Die den vorstehenden Spannverhältnissen entsprechende Seiltrommel weist somit einen doppelkonischen Verlauf auf, wobei sich die Stelle des geringsten Durchmessers außermittig zwischen den Trommelstirnseiten mit jeweils erhöhtem Durchmesser befindet. Eine solche Seiltrommelform ist nicht nur bei sehr dünnen Behängen von Bedeutung, sie kann grundsätzlich für eine besondere Zugbelastung eines Rolltorblattes in der Schließstellung Verwendung finden.The cable drum corresponding to the above tension conditions thus has a double-conical shape, the location of the smallest diameter being located off-center between the end faces of the drum, each with an increased diameter. Such a cable drum shape is not only important for very thin curtains, it can in principle be used for a special tensile load on a roller shutter door in the closed position.

Eine besondere Festlegung des Behanges 1 an der Wickelwalze 2 ist nicht erforderlich, weil der Behang nur bis auf etwa eineinviertel Umdrehungen von der Wickelwalze 2 abgewickelt wird. Es genügt somit, das walzennahe Ende des Behanges 1 auf der Wickelwalzenoberfläche an entsprechender Stelle zu fixieren, beispielswese anzukleben. Grundsätzlich ist für den Normalbetrieb der verbleibende Umschlingungswinkel des Behanges auf der Walze groß genug, um einen rutschfreien Angriff zwischen Behang und Walze auch von der Schließstellung des Behanges aus gesehen sicherzustellen.A special fixing of the curtain 1 on the winding roller 2 is not necessary because the curtain is only unwound from the winding roller 2 up to about one and a quarter turns. It is therefore sufficient that the end of the curtain 1 close to the roller on the surface of the winding roller to fix in the appropriate place, for example to glue. For normal operation, the remaining wrap angle of the curtain on the roller is large enough to ensure a non-slip attack between the curtain and the roller, even when viewed from the closed position of the curtain.

Der hier in Rede stehende verhältnismäßig dünne Behang wird um eine Walze aufgewickelt, deren Antriebswelle 3 hinsichtlich ihrer räumlichen Lage bzw. Beabstandung von dem Sturz der zu verschließenden Öffnung starr gelagert ist. Es wird also keine zwangsgesteuerte Versetzbewegung der Antriebswelle 3 in Abhängigkeit vom Bewicklungszustand der Wickelwalze 2 vorgesehen, wie dies bei dickeren Behängen oder Lamellentorblättern vorgesehen sein kann, um den ablaufenden Behang möglichst reibungs- und behinderungsfrei von dem Behangwickel in die seitlichen Führungen einbringen zu können.The relatively thin curtain in question is wound around a roller, the drive shaft 3 of which is rigidly mounted with respect to its spatial position or spacing from the lintel of the opening to be closed. There is therefore no positively controlled displacement movement of the drive shaft 3 depending on the winding condition of the winding roller 2, as can be provided for thicker curtains or lamella door leaves in order to be able to introduce the draining curtain from the curtain winding into the lateral guides as smoothly and as freely as possible.

Im vorliegenden Falle wird der Behang 1 in seine Schließebene bzw. seine seitlichen Führungen mit Hilfe einer Stützrolle 14 gelenkt, deren besonerer Aufbau nachstehend geschildert wird:In the present case, the curtain 1 is steered into its closing plane or its lateral guides with the aid of a support roller 14, the special structure of which is described below:

Die Stützrolle 14 ist mit einem schlauchartigen Gebilde 15 versehen, insbesondere einem Textil, wie Gewebe, Filz oder dergleichen, das auf die Mantelfläche eines rohrförmigen feststehenden Trägers 16 aufgeschoben und um diese herum verdrehbar an diesem gehalten ist. Das schlauchartige Gebilde 15 kann sich dabei über die gesamte Breite des Behanges erstrecken oder aber mehrteilig auf Teilbreitenbereiche des Behanges beschränkt ausgebildet und angeordnet sein. An der Außenmantelfläche dieses schlauchförmigen Gleittextils oder dergleichen greift der Behang an Durch die Bewegung des Behanges wird der Schlauch oder das Gebilde mitgenommen und in Umdrehung gegenüber dem Träger versetzt. Dabei können zwischen dem schlauchförmigen Gebilde und dem Träger Maßnahmen zur Erzielung besonders guter Gleiteigenschaften getroffen sein, dies kann durch entsprechende Werkstoffpaarung oder auch durch die Anordnung einer entsprechend gleitgünstigen Zwischenschicht erreicht werden.The support roller 14 is provided with a tubular structure 15, in particular a textile, such as fabric, felt or the like, which is pushed onto the outer surface of a tubular fixed support 16 and is rotatably held thereon. The hose-like structure 15 can extend over the entire width of the curtain or can be configured and arranged in several parts to partial width regions of the curtain. The curtain engages on the outer surface of this tubular sliding textile or the like. The movement of the curtain entrains the hose or structure and rotates it relative to the carrier. Measures to achieve particularly good sliding properties can be taken between the tubular structure and the carrier; this can be achieved by appropriate pairing of materials or by the arrangement of a corresponding one low-friction intermediate layer can be achieved.

Eine solche Stütz- oder Führungsrolle 14 kann zwischen dem Sturz und dem Behang 1 vorgesehen werden, sie kann aber auch an der zum Rauminneren hin gewandten Fläche des Behanges 1 angreifen bzw. zusätzlich in dieser Richtung angeordnet sein, so daß ein Paar solcher Führungsrollen bzw. schlauchartiger Gebilde den Behang 1 zwischen sich führen. Die Führungseigenschaften einer solchen Stützrolle 14 sind so gut, daß man auch große Ablenkungen des Behangverlaufes in Bewegungsrichtung gesehen mühelos und unter geringer Reibung und da mit Verschleiß bewältigen kann.Such a support or guide roller 14 can be provided between the lintel and the curtain 1, but it can also act on the surface of the curtain 1 facing the interior of the room or can additionally be arranged in this direction, so that a pair of such guide rollers or hose-like structure lead the curtain 1 between them. The guiding properties of such a support roller 14 are so good that even large deflections of the curtain course seen in the direction of movement can be mastered effortlessly and with little friction and with wear.

Der Träger 16 für die Aufnahme des schlauchförmigen Gebildes 15 steht fest und weist demnach nur einen Teilbereich auf, an welchem das textile Gebilde abgestützt werden muß. der Träger kann demnach in seiner Querschnittsabmessung auf einen solchen gewölbten Tragflächenbereich beschränkt sein. Es muß sich also nicht um ein Rohr handeln, es kann auch ein im Querschnitt C-förmiger oder ähnlich gestalteter Träger Verwendung finden Der Krümmungsradius des Tragflächenbereiches wird in erster Linie durch die Verformbarkeit des Behanges bestimmt. Das schlauchförmige Gebilde ist flexibler als der Behang, kann also stärkere - Krümmungen durchlaufen, so daß man mit entsprechend schmaler gehaltenen "Stützrollen" arbeiten kann, deren Träger deutlich schmaler als der doppelte Durchmesser des Krümmungsradius ist und dessen auf der Tragfläche geführter Schlauch im Ab- und Auflaufbereich der Tragfläche eine dieser gegenüber engere Biegung durchläuft.The carrier 16 for receiving the tubular structure 15 is fixed and accordingly has only a partial area on which the textile structure must be supported. the cross-sectional dimension of the carrier can accordingly be limited to such a curved wing area. So it does not have to be a tube, a support with a C-shaped cross-section or a similar design can also be used. The radius of curvature of the wing area is determined primarily by the deformability of the curtain. The tubular structure is more flexible than the curtain, so it can undergo greater curvatures, so that one can work with correspondingly narrower "support rollers", the supports of which are significantly narrower than twice the diameter of the radius of curvature and the tube guided on the wing in the end. and run-up area of the wing passes through a bend that is narrower than this.

Eine Besonderheit dieser Stützrolle 14 mit dem umlaufenden Schlauch ist noch die, daß die bewegte Masse sehr gering ist, weil der Schlauch nur eine geringe Wandstärke aufweisen muß und als einziges Teil dieser Stützeinrichtung umläuft. Lager-, Auswucht- und insoweit auch Abriebprobleme, wie sie mit denjenigen von um verhältnismäßig dünne Achsen drehbar gelagerten Rollkörpern vergleichbar wären, treten nicht auf.A special feature of this support roller 14 with the rotating hose is that the moving mass is very small because the hose only has to have a small wall thickness and is the only part of this support device that rotates. Bearing, balancing and, in so far, also abrasion problems, which would be comparable to those of rolling elements which are rotatable about relatively thin axes, do not occur.

Führungsprobleme des Schlauches gegenüber dem Träger sind verhältnismäßig geringfügig. Soweit die Tendenz eines axialen Auswanderns zwischen Schlauch und Träger besteht, kann man dem durch verschiedene Maßnahmen begegnen, beispielsweise durch radial über die Tragfläche vorstehende Flanschausbildungen des Trägers, gegen die der axial bewegte Schlauch anläuft, und zwar vorzugsweise in diesem Anlaufbereich axial verdickt, beispielsweise durch Umschlagen des Schlauches auf sich selbst gebildete Schlauchkanten, Anordnen einer gute Gleiteigenschaften aufweisende Scheibe axial zwischen dem anlaufenden stirnseitigen Schlauchende und dem benachbarten Trägerflansch und dergleichen mehr. Ein solcher radial abstehender Flansch kann beispielsweise durch eine sogenannte Bundbuchse gebildet sein, die einen zylindrischen Teil aufweist, auf den der Schlauch aufgeschoben wird und die mit einem radial abstehenden Teil versehen ist, der die eigentliche stirnseitige Anlauf- bzw. Gleitfläche bildet. Weiterhin kann man den Träger im Tragflächenbereich oder auch durchgehend ballig ausbilden oder eine solche Balligkeit dadurch immitieren, daß man einige Stege auf dem Träger zur axialen Mitte hin mit steigendem Durchmesser ausgebildet vorsieht und dergleichen mehr. Die zu treffende Maßnahme hängt weitgehend von der Konsistenz des Schlauchmaterials ab; ein steifer Schlauch kann sich selbst führen, während ein in axialer Richtung zum Aufwölben oder Zusammendrücken neigender Schlauch im Endbereich gegebenenfalls gesondert gefaßt werden muß (Bundbuchse).Problems with the guidance of the hose relative to the carrier are relatively minor. Insofar as there is a tendency of the tube and carrier to migrate axially, this can be countered by various measures, for example by flange designs of the carrier projecting radially over the wing, against which the axially moving tube runs, and preferably axially thickened in this starting area, for example by Turning over the hose onto self-formed hose edges, arranging a disc with good sliding properties axially between the approaching end of the hose end and the adjacent carrier flange and the like and more. Such a radially projecting flange can be formed, for example, by a so-called collar bushing which has a cylindrical part, onto which the hose is pushed and which is provided with a radially projecting part, which forms the actual end face or sliding surface. Furthermore, one can make the carrier spherical in the wing area or also continuously or imitate such crowning by providing some webs on the carrier towards the axial center with increasing diameter and the like and more. The measure to be taken largely depends on the consistency of the hose material; a rigid hose can guide itself, while a hose that tends to bulge or compress in the axial direction may have to be seized separately in the end region (collar bushing).

Bei dieser Ausgestaltung der Stützrolle 14 lassen sich Feuchtigkeitsprobleme durch entsprechende Oberflächenvergütung des Trägers, durch Kunststoffbeschichtungen oder dergleichen auffangen.In this configuration of the support roller 14, moisture problems can be compensated for by appropriate surface treatment of the carrier, by plastic coatings or the like.

Wie eingangs ausgeführt, müssen die Zugseile dem Rillenverlauf folgend auf die konischen Seiltrommeln 4 aufgewickelt werden. Vor allem dann, wenn die im Zargenseitenbereich untergebrachte Flasche 7, 8 nebst Zugfeder 10 in eine Abdeckung 17 aufgenommen sind und/oder wenn aufgrund der Anordnung einer Stützrolle 14 unterhalb der Wickelwalze 2 bzw. den Seiltrommeln 4 ein entsprechender Auflaufabstand gegeben ist, kann es ratsam oder erforderlich sein, unterhalb der Stützrolle in jedem Seitenbereich des Zargenrahmens eine Seilrolle anzuordnen, die der Führung des Zugseiles 5 vom Längsverlauf parallel zur Seitenzarge zu der Rillenführung auf der zugehörigen konischen Seiltrommel 4 übernimmt, demnach sowohl hinsichtlich der Seilablenkung um die Welle 3 herum als auch in Achsrichtung der Welle verteilend, um das Seil auf die mit entsprechend schraubenförmiger Rille versehene Seiltrommel unter entsprechender Achsversetzung zu verteilen.As stated at the beginning, the traction ropes have to be wound onto the conical rope drums 4 following the course of the groove. Especially when the bottle housed in the frame side area 7, 8 together with tension spring 10 are accommodated in a cover 17 and / or if there is a corresponding run-up distance due to the arrangement of a support roller 14 below the winding roller 2 or the cable drums 4, it may be advisable or necessary below the support roller in each side area of the frame frame to arrange a rope pulley, which takes over the guidance of the pull rope 5 from the longitudinal course parallel to the side frame to the groove guide on the associated conical rope drum 4, thus distributing the rope around the shaft 3 as well as in the axial direction of the shaft, around the rope to distribute the cable drum, provided with a corresponding helical groove, with the appropriate axis offset.

Die Befestigung des Zugseiles bzw. des trommelseitigen Zugseilendes an der Seiltrommel kann unter ähnlichen Gesichtspunkten montagetechnisch einfach gestaltet erfolgen, wie dies im Zusammenhang mit der Halterung des Behanges auf der Wickelwalze 2 geschildert wurde. Wenn man dafür sorgt, daß etwa eine Windung des Zugseiles auf der Seiltrommel verbleibt, genügt die Reibung, um das Seil auf der Trommel ohne besondere Festlegung zu halten. Beispielsweise kann man das Seilende einfach durch ein radial gerichtetes Loch im Anfangsbereich der spiraligen Rille stecken, wodurch die Montage sehr einfach wird.The fastening of the traction cable or the drum-side traction cable end to the cable drum can be carried out in a simple manner from an assembly point of view, similar to that described in connection with the holding of the curtain on the winding roller 2. If you make sure that one turn of the pull rope remains on the rope drum, the friction is sufficient to hold the rope on the drum without any special definition. For example, you can simply put the end of the rope through a radially directed hole in the beginning of the spiral groove, which makes assembly very easy.

Wenn man die Festlegung des trommelseitigen Zugseilendes nicht im Verlauf der Aufnahmrille für das Seil vorsieht, sondern den für die Halterung letzten Abschnitt in einer entsprechenden Ausnehmung an der diesem Rillenanfangsbereich benachbart zugeordneten Stirnseite der als Gußkörper ausgebildeten Seiltrommel vorsieht, kann man die axiale Abmessung der Seiltrommel 4 entsprechend kleiner halten. Es ergibt sich dann für diesen letzten Rillenabschnitt, der nicht mehr in den Führungsverlauf der Rille eingeht, ein Verlauf nach Art einer archimedischen Spirale.If one does not provide for fixing the end of the pull rope on the drum in the course of the receiving groove for the rope, but instead provides the last section for the holder in a corresponding recess on the end face of the rope drum designed as a casting, which is adjacent to this groove start area, the axial dimension of the rope drum 4 can be seen keep smaller accordingly. The result for this last groove section, which no longer goes into the guide course of the groove, is a course in the manner of an Archimedean spiral.

Es ist ohne weiteres verständlich, daß man eine derartige Halterung zwischen Zugseil und Seiltrommel auch in anderem Zusammenhang als in dem vorgeschilderten Rolltoraufbau mit dünnem Behang verwenden kann, so auch bei Deckengliedertoren, deren Torunterkante mit Seilen gehalten ist, die auf Seiltrommeln auf- und ablaufen.It is easy to understand that such a bracket can also be used between the pulling rope and the rope drum in a different context than in the roller shutter structure described above with thin curtains, so also in the case of sectional gates whose lower edge of the door is held with ropes that run up and down on rope drums.

Vor allem wird betont, daß der vorstehend geschilderte Stützkörper nicht auf die Verwendung bei dünnwandigen Behängen von Rolltoren beschränkt ist, sondern Rolltorblätter allgemein führen kann, vor allem auch solche, die aus einem dickeren und/oder steifern, insbesondere mehrschichtigen Behang bestehen. Dabei können die besonders guten Führungseigenschaften solcher Stützrollen dazu führen, daß man auf eine ansonsten erforderliche Nachführung der Wickelwalzenwelle in Abhängigkeit von der abgerollten Torblattlänge zur Einleitung in die Torblattführungen verzichten kann.Above all, it is emphasized that the above-described support body is not limited to use with thin-walled curtains of roller doors, but can generally lead roller door leaves, especially those that consist of a thicker and / or stiffer, in particular multi-layered curtain. The particularly good guiding properties of such support rollers can lead to the fact that there is no need to adjust the winding roller shaft as a function of the unrolled door leaf length for introduction into the door leaf guides.

Wie insbesondere aus Figur 4 ersichtlich, wird die Unterkante des Torblattes durch eine Behang-Abschlußschiene 13 gebildet, die aus wenigstens zwei Hohlkammerprofilen 18 und 19 besteht, deren eines als Grundkörper 18 ausgebildet ist, in welchen das andere, als Abdeckteil 19 dienende Profil einhängbar ist, wozu eine in Profillängsrichtung entsprechend ausgebildete im Querschnitt hakenförmige Ausformung 20 an dem Abdeckteil 19 einen in die hakenförmige Ausnehmung eingreifenden Steg 21, der an dem Grundkörper 18 vorgesehen ist, übergreift. Dadurch wird zwischen den beiden Profilteilen 18 und 19 eine Art Scharnierbewegung um eine in Breitenrichtung des Behanges verlaufende Achse möglich. Die beiden Teile 18 und 19 bilden zur Unterkante des Behanges hin gewendet ein durch die Scharnierbewegung zu öffnendes und zu schließendes Klauenmaul, in welches im Öffnungszustand der Schließkantenbereich des Behanges 1 eingesetzt wird. Das dann durch Schließen des Klauenmauls stattfindende Ergreifen des Schließkantenbereichs des Behanges 1 efolgt über die Behangbreite hinweg und wird fixiert durch eine Verschraubung, die die beiden Teile 18 und 19 unter Durchgreifen des Behang-Schließkantenbereiches gegeneinander verspannt. Zu diesem Zwecke weist das Abdeckteil 19 einen im Querschnitt rechteckförmigen Hohlraum 22 auf, in welchen nicht dargestellte, in Breitenrichtung des Behanges 1 beabstandete Schrauben aufgenommen sind, die durch den Behang 1 hindurch in einen Profilabschnitt 23 des Grundkörpers 18 eingreifen und in diesem verschraubt sind. Das Abschlußleistenprofil des Behanges ist mit einem nach unten hin abragenden Gummidichtungswulst versehen und trägt in üblicher Weise an der Frontseite des Abdeckteils 19 eine gelb-schwarze Warnmarkierung 24.As can be seen in particular from Figure 4, the lower edge of the door leaf is formed by a curtain end rail 13, which consists of at least two hollow chamber profiles 18 and 19, one of which is designed as a base body 18, in which the other, serving as a cover part 19 profile can be hung , for which purpose a cross-sectionally shaped 20 in the longitudinal section of the profile on the cover part 19 engages over a web 21 which engages in the hook-shaped recess and is provided on the base body 18. As a result, a kind of hinge movement around an axis running in the width direction of the curtain is possible between the two profile parts 18 and 19. The two parts 18 and 19, facing the lower edge of the curtain, form a claw mouth that can be opened and closed by the hinge movement and into which the closing edge region of the curtain 1 is inserted in the open state. The gripping of the closing edge area of the curtain 1, which then takes place by closing the claw mouth, takes place across the width of the curtain and is fixed by a screw connection which braces the two parts 18 and 19 against one another while reaching through the curtain closing edge area. For this purpose, the cover part 19 a cavity 22 with a rectangular cross-section, in which screws, not shown, spaced apart in the width direction of the curtain 1 are received, which engage through the curtain 1 into a profile section 23 of the base body 18 and are screwed therein. The end strip profile of the curtain is provided with a rubber sealing bead protruding downwards and bears a yellow-black warning marking 24 on the front of the cover part 19 in the usual way.

Auch diese Einzelheit der besonderen Ausbildung des Abschlußprofils an der Schließkante des Behanges ist nicht auf die vorstehenden Ausführungsmerkmale der übrigen Torausbildung beschränkt, sondern kann auch bei ähnlichen und dicker ausgeführten Behängen Verwendung finden.This detail of the special design of the end profile at the closing edge of the curtain is not limited to the above design features of the other door design, but can also be used with similar and thicker curtains.
