Abstract

The subject matter of the invention is a covering which can be unrolled, as is, in particular, frequently expedient for shading purposes for glass roofs. The covering (5), usually consisting of canvas, is subjected to very high tensile forces during operation, with the result that the yield point of the warp threads is easily exceeded, this having the effect that it can no longer extend in a planar surface. The invention eliminates this disadvantage in that the diameter of the fully wound-up covering roll (1) and of the base of the winding-up reel (3) on which the tension means are seated are of essentially the same size. In this arrangement, in the rolled-in state of the covering, the tensile stressing is virtually 0, whereas the highest tensile-stressing value exists into the stretched-out state. <IMAGE>

Description

STAND DER TECHNIK: PRIOR ART :

Die Erfindung erstreckt sich auf eine abrollbare Abdeckung für sich im wesentlichen horizontal erstreckende Flächen von Bauwerken, insbesondere von Glasdächern.The invention extends to a rollable cover for essentially horizontally extending surfaces of buildings, in particular glass roofs.

Zum Aufwickeln und Abwickeln der Abdeckung findet eine Abdeckungsrolle Verwendung, auf der sich die Abdeckungsrolle aufwickeln läßt. Dabei sind für die Abdeckungsrolle ortsfeste Lagerböcke vorgesehen.A cover roll is used to wind up and unwind the cover, on which the cover roll can be wound up. Fixed bearing blocks are provided for the cover roller.

Die ausfahrbaren Enden der Abdeckung sind in einer Saumstange gehalten, deren Enden in Führungsschienen antreibbar sind, so daß mittels der Saumstangen die Abdeckung im vorgesehenen Ausmaß abgerollt sind, während das Zugmittel um eine vordere Umlenkrolle um 180° umgelenkt und auf der Aufwickelrolle aufwickelbar ist.The extendable ends of the cover are held in a hemming rod, the ends of which can be driven in guide rails, so that the cover is rolled off to the intended extent by means of the hemming rods, while the traction device is deflected by a front deflecting roller by 180 ° and can be wound up on the winding roller.

Nach Maßgabe eines Spannungsausgleichs zwischen der Abdeckungsrolle und der seitlich derselben vorgesehenen Aufwickelrolle besteht für das Zugmittel eine elastische Verbindung.In accordance with a tension compensation between the cover roller and the winding roller provided on the side thereof, there is an elastic connection for the traction means.

BESCHREIBUNG: DESCRIPTION :

Eine derartige abrollbare Abdeckung ist beispielsweise nach der DE-PS 36 10 635 bekannt. Dabei steht die Abdeckung in ganz eingefahrenem und ganz ausgefahrenem Zustand unter stärkster Spannung. Für die elastische Verbindung zwischen Abdeckungsrolle und Aufwickelrolle sind Windungen einer Schraubenfeder, zwischen beiden Rollen vorgesehen, die bei zunehmendem Abrollen der Abdeckung ihren Durchmesser verkleinern und deshalb das von ihnen eingeschlossene Rohr einklemmen können.Such a rollable cover is known for example from DE-PS 36 10 635. The cover is under extreme tension when fully retracted and fully extended. For the elastic connection between the cover roll and the take-up roll, coils of a helical spring are provided between the two rolls, which decrease in diameter as the cover unrolls and can therefore pinch the tube enclosed by them.

Wenn die Abdeckung zunehmend bis etwa zur Hälfte der Ausfahrbewegung abgerollt wird, geht die Spannung zurück, und steigt danach wieder an, so daß die Kettfäden der normalerweise als Tuch ausgeführten Abdeckung schließlich überdehnt werden mit der Folge, daß zumindest eine glatt gespannte Abdeckung nicht mehr herstellbar ist.If the cover is increasingly rolled up to about half of the extension movement, the tension drops and then rises again, so that the warp threads of the cover, which is normally designed as a cloth, are finally overstretched, with the result that at least a smoothly stretched cover can no longer be produced is.

Nach dem Stand der Technik können als Zugmittel Seile, Bänder, Riemen, Keil- oder Zahnriemen aus Metall oder organischen Materialien, die sich nicht recken, bestehen. Abwandlungen bestehen darin, den elastischen Ausgleich für die unterschiedlichen Wickeldurchmesser in Form von Torsionsfedern oder Zugfedern vorzunehmen, die auf die vordere Saumstange einwirken. Die Aufwickelrollen sind zumeist als Scheiben auf die Achse der Abdeckungsrolle aufgesetzt.According to the prior art, ropes, tapes, belts, V-belts or toothed belts made of metal or organic materials that do not stretch can exist as traction means. Modifications consist in making the elastic compensation for the different winding diameters in the form of torsion springs or tension springs which act on the front hem bar. The take-up rolls are usually placed as disks on the axis of the cover roll.

Allgemein wird beim Abwickeln der Abdeckung von der Abdeckungsrolle die Aufwickelrolle durch das Aufrollen des Zugmittels belegt, wobei während des Abwickelns die Abdeckung von der Abdeckungsrolle ihre geringer werdenden Durchmesser und die durch das Aufwickeln auf die Aufwickelrollen größer werdenden Durchmesser der Aufwickelrollen dadurch einander entsprechen, daß die elastische Verbindung zweckentsprechend gewählt wird. Dies geschieht dadurch, daß die Federn zum Ausgleich entsprechend vorgespannt werden, so daß die halb ausgefahrene Abdeckung nicht durchhängt. Dies hat dann aber zur Folge, daß die Abdeckung beim Aus- bzw. Einfahren immer mehr unter zunehmender Spannung steht.In general, when the cover is unwound from the cover roll, the take-up roll is occupied by rolling up the traction means, whereby during unwinding, the cover from the cover roll becomes smaller in diameter and the diameter of the wind-up rolls becomes larger due to the winding on the take-up rolls in that the elastic connection is chosen appropriately. This is done by appropriately pretensioning the springs so that the half-extended cover does not sag. However, this has the consequence that the cover is increasingly under increasing tension when extending or retracting.

Dieser starken Spannung, insbesondere bei der Einfahrbewegung über den halb eingefahrenen Zustand nach oben hinausgehend, ist das Abdeckungstuch nicht gewachsen, und es kommt unter Einwirkung der vorstehend beschriebenen Kräfte zu einer Ausreckung auch der Nähte mit wellenartigen Verformungen.This strong tension, in particular when the retracting movement goes upwards over the half-retracted state, is not sufficient for the cover sheet, and the seams with wave-like deformations are also stretched out under the action of the forces described above.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Abdeckung der als gattungsgemäß vorausgesetzten Art die Zugspannung in den Bereichen zu halten, in denen die Streckgrenze nicht überschritten wird. Diese Verbindung soll bei eingefahrener Abdeckung die geringstmögliche und in ganz ausgerolltem Zustand die höchstmögliche Spannung aufweisen, die die Abdeckung zuläßt. Für die Einstellung der elastischen Verbindung müssen die Abdeckungslänge und das Gewicht derselben berücksichtigt werden.The object of the invention is to maintain the tensile stress in the areas in which the yield strength is not exceeded with a cover of the type required as a generic type. When the cover is retracted, this connection should have the lowest possible and, in the fully rolled out state, the highest possible tension that the cover permits. To adjust the elastic connection, the length of the cover and the weight of the same must be taken into account.

Die Erfindung löst diese Aufgabenstellung durch die Vorschläge der Patentansprüche.The invention solves this problem by the proposals of the claims.

Dadurch wird zumindest bei der ersten Abwicklungslänge der Abdeckung gewährleistet, daß das Zugmittel wenigstens am Ende der ersten Umdrehung der Abdeckung in gleicher Länge von der Aufwickelrolle übernommen wurde. Dies bedeutet, daß die Spannungsverhältnisse konstant bleiben. Sofern die Dicke von Zugmittel einerseits und Abdeckung andererseits höchstens gleich sind, besteht für die erste Abwicklungslänge der Aufwickelrolle eine Strecke zur Aufwicklung, bei der noch keine oder nur sehr geringe Spannungen zustande kommen. Die zweite Aufwicklungslänge des Zugmittels ist aber schon länger als die zweite Abdeckungslänge der Abdeckung. Somit wird die entstehende Spannung größer. Im weiteren Verlauf der Auf- bzw. Abwicklungslängen wird die Zugspannung weiterhin größer, wobei sie linear mit der Abwicklung ansteigt. Die maximale Spannung besteht dann bei ganz abgewickelter Abdeckung. Diese Verhältnisse sind umkehrbar, d. h., für die Abwicklung ergeben sich genau die gleichen Verhältnisse, nämlich die Linearität der Spannung in Bezug auf die Abrollänge des Zugmittels.This ensures, at least for the first unwinding length of the cover, that the traction means has been taken over by the winding roller in the same length at least at the end of the first rotation of the cover. This means that the tension remains constant. Provided the thickness of the traction device is and coverage, on the other hand, are at most the same, there is a stretch for winding up for the first unwinding length of the take-up reel, in which no or only very low tensions occur. However, the second winding length of the traction device is already longer than the second cover length of the cover. The resulting voltage increases. In the further course of the winding or unwinding lengths, the tensile stress continues to increase, increasing linearly with the unwinding. The maximum tension is then with the cover completely unwound. These ratios are reversible, ie, exactly the same ratios result for the unwinding, namely the linearity of the tension in relation to the rolling length of the traction means.

Als Absicherung der vorgeschlagenen Maßnahmen dreht sich die Aufwickelrolle bei jeder Drehung der Abdeckungsrolle über die elastische Verbindung mit.To secure the proposed measures, the winding roller rotates with the rotation of the cover roll every time the elastic connection is used.

Die Erfindung sei weiterhin anhand der schematischen Zeichnungen veranschaulicht.The invention is further illustrated by the schematic drawings.

Figur 1 und Figur 2 zeigen in schematischer Weise die Funktion der neuen Abdeckung.Figure 1 and Figure 2 schematically show the function of the new cover.

Demgemäß ist die Abdeckungsrolle bzw. Tuchrolle 1 in Figur 1 von der tuchartigen Abdeckung 5 belegt. Zum Ausfahren ist das Ende derselben in die Saumstange 6 eingelegt. Das Zugmittel (4) ist mit seinem einen Ende an der Aufwickelrolle 3 befestigt, so daß der Grund 2, an welchem das Zugmittel 4 aufliegt, frei erscheint. Das Zugmittel 4 wird über die Umlenkrolle 7 in vorgegebener Spur zur Anlage auf dem Grund 2 der Aufwickelrolle 3 gebracht, wobei erkennbar der gleiche Durchmesser im Grund 2 wie bei der obersten Lage der Abdeckung 5 besteht. Letztere gelangt über hier nicht dargestellte, etwa horizontal verlaufende Führungsschienen zu dem vorderen Umlenkkopf 8, um welchen das Zugmittel 4, insbesondere ein Band, um 180° umgelenkt und über die Umlenkrolle 7 zur Aufwickelrolle 3 geführt ist.Accordingly, the cover roll or cloth roll 1 in Figure 1 is covered by the cloth-like cover 5. To extend the end of the same is inserted into the hem bar 6. The traction device (4) is with one end attached to the take-up reel 3, so that the base 2, on which the traction means 4 rests, appears free. The traction means 4 is brought to rest on the base 2 of the take-up roller 3 in the predetermined track via the deflection roller 7, the diameter of the base 2 evidently being the same as that of the top layer of the cover 5. The latter reaches the front deflection head 8 via guide rails (not shown here) which run approximately horizontally, around which the traction means 4, in particular a belt, is deflected by 180 ° and is guided via the deflection roller 7 to the winding roller 3.

Während Figur 1 die vollständige Aufwicklung der Abdeckung 5 wiedergibt, zeigt Figur 2 dessen vollständige Abwicklung. Die Abdeckungsrolle 1 ist also leer, wohingegen die Aufwickelrolle 3 voll belegt ist. Dies entspricht dem Zustand der vorgegebenen äußersten Spannung, wie sie sich nur in der Endlage des ausgefahrenen Zustandes einstellt.While Figure 1 shows the complete winding of the cover 5, Figure 2 shows the complete winding. The cover roll 1 is therefore empty, whereas the take-up roll 3 is fully occupied. This corresponds to the state of the predetermined extreme tension, which only occurs in the end position of the extended state.

In Figur 3 ist die Saumstange 6 rohrförmig ausgeführt, wobei auf die offenen Rohrenden Endkappen 9 eingesetzt sind. Diese sind von Lagerbolzen 10 durchsetzt, an deren Enden sich die Lager für die Laufrollen und die Zugösen befinden. An letzteren greifen die Endhaken 11 des Zugmittels 4 an. Für die Laufrollen bestehen die Führungsschienen 12. Die Abdeckungsrolle 1 besteht ebenfalls aus einem Rohr, in dessen Inneres von beiden Seiten her Lagerzapfen 14 eingreifen. Diese sind in den die Abdeckungsrolle 1 stirnseitig eingreifenden Federköpfen 13 gelagert, die nach außen zu die Aufwickelrollen 3 lagern, und die nach innen zu Befestigungspunkte für die Enden der Torsionsfedern 15 bilden. Dabei umschließen die Torsionsfedern 15 die Lagerzapfen 14 bis zu ihren inneren Enden, die mit Mitnehmerscheiben 16 für die begrenzte Mitnahme der Lagerzapfen 14 durch die Abdeckungsrolle 1 ausgeführt sind. Die Federköpfe 13 übertragen die Kraft der Torsionsfedern 15 auf die Aufwickelrolle 3, die auf den Lagerzapfen 14 angeordnet sind, und für die die Stirnlager 17 bestehen. Letztere sind in Lagerböcken 25 angeordnet, deren Gehäuse 18 mit seiner Rückwand 21 an der Wand eines Gebäudes anschließt. Zwischen den Federköpfen 13 und der Abdeckungsrolle 1 sind Abstandringe 24 eingesetzt.In Figure 3, the hem bar 6 is tubular, end caps 9 being inserted on the open tube ends. These are penetrated by bearing bolts 10, at the ends of which are the bearings for the rollers and the drawbar eyes. The end hooks 11 of the traction means 4 act on the latter. The guide rails 12 exist for the rollers. The cover roller 1 also consists of a tube, in the interior of which bearing pins 14 engage from both sides. These are mounted in the spring rollers 13 engaging on the end face of the cover roller 1, which support the winding rollers 3 to the outside, and which form inward fastening points for the ends of the torsion springs 15. The torsion springs 15 enclose the bearing pins 14 up to their inner ends, which are designed with drive plates 16 for the limited entrainment of the bearing pins 14 by the cover roller 1. The spring heads 13 transmit the force of the torsion springs 15 to the take-up reel 3, which are arranged on the bearing pin 14, and for which the Front bearing 17 exist. The latter are arranged in bearing blocks 25, the housing 18 of which connects with its rear wall 21 to the wall of a building. Spacer rings 24 are inserted between the spring heads 13 and the cover roller 1.

Figur 4 zeigt die Vorderansicht. Vor der Saumstange 6 liegen die in der Bewegungsrichtung der Abdeckung vorher befindlichen Umlenkköpfe 8, um welche das Zugmittel um 180° umgelenkt ist. Das Gehäuse, dessen Gehäusedeckel 19 und Gehäuseboden 20 erkennbar sind, ist mit seiner in Figur 5 dargestellten Rückwand 21 beispielsweise an einer Hauswand angestoßen. Es trägt den Lagerbock 25, in welchem das Rollensystem in der beschriebenen Weise gelagert ist, und der gleichzeitig als Seitendeckel für das Gehäuse dient. Ferner sind Montageböcke 22 vorgesehen, mit denen das Gesamtsystem z.B. auf den Abdeckungsprofilen eines Glasdaches montiert ist. Das Zwischenrollenlager 23 dient der Lagerung einer die Lage der Abdeckung stabilisierenden Zwischenrolle.Figure 4 shows the front view. In front of the hem bar 6 are the deflecting heads 8 located in the direction of movement of the cover, around which the traction means is deflected by 180 °. The housing, the housing cover 19 and the housing base 20 of which can be seen, is abutted with its rear wall 21 shown in FIG. 5, for example on a house wall. It carries the bearing block 25, in which the roller system is mounted in the manner described, and which also serves as a side cover for the housing. Furthermore, mounting brackets 22 are provided, with which the overall system e.g. is mounted on the cover profiles of a glass roof. The intermediate roller bearing 23 serves to support an intermediate roller which stabilizes the position of the cover.
