Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf eine Spannvorrichtung für ein von einer Wickelwelle abziehbares Sonnensegel mit einem durch wenigstens eine Feder beaufschlagten Spannseil, wobei die Feder als Gasfeder zum Spannen des Seilspeichers ausgebildet ist, der zwei mit Hilfe der Gasfeder gegeneinander verstellbare Spannrollensätze für das zwischen den Spannrollensätzen schlingenbildend hin- und hergeführte Spannseil aufweist.The invention relates to a tensioning device for a deductible from a winding shaft awning with an acted upon by at least one spring tensioning cable, wherein the spring is designed as a gas spring for tensioning the cable storage, the two with the help of the gas spring mutually adjustable clamping roller sets for the loop between the sets of tension rollers has reciprocating tensioning cable.

Stand der TechnikState of the art

Um ein Sonnensegel, das entlang einer Teilungslinie mit einer Wickelwelle verbunden ist und an den von der Teilungslinie abgekehrten Enden in entgegengesetzten Richtungen von der Wickelwelle abgezogen werden kann, in einfacher Weise auf die Wickelwelle aufzuwickeln und von ihr abzuziehen. ist es bekannt ( EP 0 865 557 B1 ), die Wickelwelle mit einem Antrieb zu versehen und die zum Abziehen des Sonnensegels benötigten Seilzüge, die an den von der Teilungslinie abgekehrten Enden des Sonnensegels angreifen, über Umlenkrollen zur Wickelwelle zurückzuführen und auf mit der Wickelwelle drehfest verbundenen Wickelrollen zu befestigen, sodass bei einer Drehung der Wickelwelle im Abwickelsinn das Sonnensegel mit Hilfe der sich auf den Wickelrollen als Seilspeicher aufwickelnden Seilzüge von der Wickelwelle abgezogen wird, und zwar im Ausmaß seiner Abwicklung von der Wickelwelle. Zum Ausgleich etwaiger Längenunterschiede und zum Spannen des Sonnensegels sind unter einer federnden Vorspannung stehende Spanneinrichtungen zwischen den Seilzügen vorgesehen. Nachteilig bei solchen auf- und abwickelbaren Sonnensegeln ist allerdings, dass mit der zusätzlichen Rückführung der Seilzüge zur Wickelwelle und den zwischen den rückgeführten Seilzügen vorgesehenen Spanneinrichtungen ein erheblicher Konstruktionsaufwand verbunden ist. Außerdem reicht die durch die Spanneinrichtung gegebene, federnde Abspannung der Seilzüge nicht aus, um die tragende Konstruktion und das Sonnensegel vor einer Überlastung beispielsweise durch Windböen oder Niederschläge zu bewahren. Dazu kommt, dass die Wickelwelle mit dem Antrieb zum Auf- und Abwickeln des Sonnensegels ausreichend biegesteif auszubilden ist, was bei einer entsprechenden Begrenzung des Wickelwellendurchmessers zu einer Beschränkung der Sonnensegelgröße führt.To a sun sail, which is connected along a dividing line with a winding shaft and can be deducted in opposite directions from the winding shaft at the ends facing away from the dividing line, easy to wind on the winding shaft and deducted from it. it is known ( EP 0 865 557 B1 ), to provide the winding shaft with a drive and required for removing the awning cables that engage the remote from the dividing line ends of the awning, via pulleys to the winding shaft and attach to the winding shaft rotatably connected winding rollers, so that upon rotation the winding shaft in Abwickelsinn the awning with the help of winding on the winding rollers as cable storage cables is subtracted from the winding shaft, in the extent of its settlement of the winding shaft. To compensate for any differences in length and for tensioning the solar sail standing tensioning devices are provided between the cables under a resilient bias. A disadvantage of such windable and unwindable sun sails, however, is that associated with the additional return of the cables to the winding shaft and provided for between the returned cables tendons a significant design effort. Furthermore the given by the tensioning device, resilient bracing the cables is not sufficient to protect the supporting structure and the sun sails from overloading, for example, by gusts of wind or precipitation. In addition, the winding shaft with the drive for winding and unwinding of the solar sail is sufficiently rigid form, resulting in a corresponding limitation of the winding shaft diameter to a limitation of the sun sail size.

Um bei Markisen zum Abschatten trapez- oder dreieckförmiger Fensterflächen mit einer längs einer Unterkante angeordneten, mit einem Antrieb versehenen Wickelwelle für das mit vorlaufender Spitze über einen Seilozug nach oben abwickelbare Markisetuch vorteilhafte Konstruktionsverhältnisse zu schaffen, ist es bereits bekannt ( DE 197 06 251 A1 ), längs der zueinander geneigten Seitenkanten in Längsschienen angeordnete Gasfedern vorzusehen, die mittels Seilzügen, die nach Art von Flaschenzügen über Umlenkrollen am oberen festen Ende der Gasfedern geführt sind, mit der Spitze des Markisentuchs zu verbinden. Mithilfe der Gasfedern ist allerdings kein Antrieb der Wickelwelle im Aufwickelsinn möglich.In order to provide awning for trapezoidal or triangular window surfaces with a along a lower edge, provided with a drive winding shaft for the leading edge with a Seilozug developable upwards awning cloth advantageous construction conditions, it is already known ( DE 197 06 251 A1 ), along the mutually inclined side edges arranged in longitudinal rails to provide gas springs to connect by means of cables, which are guided in the manner of pulleys over pulleys at the upper fixed end of the gas springs, with the tip of the awning fabric. By means of the gas springs, however, no drive of the winding shaft in the winding direction is possible.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt somit die Aufgabe zugrunde, eine Spannvorrichtung für ein Sonnensegel der eingangs beschriebenen Art so auszubilden, dass sie eine gute Abspannung des Sonnensegels über die gesamte Ausziehlänge ermöglicht und die Voraussetzung mit sich bringt, im Aufwickelsinn wirksam zu werden.The invention is therefore based on the object, a tensioning device for an awning of the type described above in such a way that it allows a good bracing of the awning over the entire extension length and brings the requirement to be effective in Aufwickelsinn.

Die Erfindung löst die gestellte Aufgabe dadurch, dass die Gasfeder mit dem Seilspeicher in einem rohrförmigen Steher angeordnet ist, dass das Spannseil an einer mit der Wickelwelle antriebsverbundenen, am oberen Ende des rohrförmigen Stehers angeordneten Wickelrolle für das Spannseiltrum angreift, deren zur Steherachse senkrechte Welle den rohrförmigen Steher oder einen Lagerbock für die Wickelrolle durchsetzt und mit der Wickelwelle antriebsverbunden ist.The invention solves this problem by the fact that the gas spring is arranged with the cable storage in a tubular uprights, that the tensioning cable is connected to a drive connected to the winding shaft, arranged at the upper end of the tubular stirrup winding roll for the tensioning cable strand whose vertical axis to the vertical axis of the tubular stand or a bearing block penetrated for the winding roll and is drivingly connected to the winding shaft.

Da ein über einen Seilspeicher geführtes Spannseil zum Einsatz kommt und der Seilspeicher im Sinne einer Seilaufnahme federnd vorgespannt ist, kann über die gesamte Ausziehlänge des Spannseils aus dem Seilspeicher eine von der Federbelastung des Seilspeichers abhängige Rückzugskraft sichergestellt werden, und zwar mit einem Kraftverlauf, der sich wegen der Verwendung einer Gasfeder über die Ausziehlänge nur vergleichsweise geringfügig ändert. Es ergeben sich somit vorteilhafte Abspannbedingungen unabhängig von der Größe des Sonnensegels, weil der Seilspeicher aufgrund der schlingenbildenden Spannseilführung zwischen zwei Spannrollensätze trotz eines beschränkten Federweges durch die Wahl der Anzahl der Seilschlingen zwischen den Spannrollen in einfacher Weise an die jeweilige Größe des zu spannenden Sonnensegels angepasst werden kann.Since a guided via a rope store tensioning cable is used and the cable storage is resiliently biased in the sense of a rope receiving, can be ensured over the entire extension length of the tensioning cable from the cable storage a dependent on the spring load of the rope storage retraction force, with a force curve, the itself because of the use of a gas spring on the Ausziehlänge changes only slightly. This results in advantageous Entspannbedingungen regardless of the size of the awning, because the cable storage are adapted due to the loop-forming tension cable between two sets of tension pulleys despite a limited suspension travel by the choice of the number of loops between the tension rollers in a simple manner to the respective size of exciting awning can.

Dies gilt auch für den Einsatz der Spannvorrichtung zum Aufwickeln des Sonnensegels. Zum Aufwickeln des Sonnensegels wird das Spannseil an einer mit der Wickelwelle antriebsverbundenen Wickelrolle befestigt, die daher mit einem im Aufwickelsinn wirksamen Drehmoment beaufschlagt wird. Ein zum Abziehen des Sonnensegels von der Wickelwelle vorgesehener Antrieb, der an einem am Sonnensegel angreifenden Seilzug zum Abziehen des Sonnensegels anzuschließen ist, muss daher das Sonnensegel entgegen dem durch den Seilspeicher bedingten Rückhaltemoment abziehen, was die erforderliche federnde Abspannung des Sonnensegels über die Wickelwelle erlaubt, und zwar auch dann, wenn von einer starren Wickelwelle Abstand genommen und eine Wickelwelle in Form eines zwischen Wellenstummeln gespannten Seilzuges verwendet wird, sodass Sonnensegel auch mit größeren Segelflächen vorteilhaft abgespannt werden können.This also applies to the use of the tensioning device for winding up the awning. To wind the sun sail, the tensioning cable is fastened to a drive roller connected to the winding shaft winding roller, which is therefore acted upon by a force acting in the Aufwickelsinn torque. A provided for pulling off the awning of the winding shaft drive, which is to be connected to an attacking the sun sail for pulling off the awning, therefore, deduct the sun sail against the restraint caused by the rope storage, which allows the required resilient bracing of the sun sail over the winding shaft, even if taken from a rigid winding shaft distance and a winding shaft is used in the form of a stretched between stub sheave cable, so that sun sails can be advantageously covered with larger sail areas.

Üblicherweise umfasst die Tragkonstruktion für ein Sonnensegel der beschriebenen Art zumindest zwei Steher, an denen das Sonnensegel abgespannt wird. Wird die Gasfeder mit dem Seilspeicher in einem dieser rohrförmigen Steher angeordnet, so ergeben sich besonders einfache Konstruktionsverhältnisse, weil weder die Gasfeder noch der Seilspeicher gesondert untergebracht werden müssen. Da das Spannseil an der Wickelrolle angreift, die mit der Wickelwelle drehfest zu verbinden ist, kann der rohrförmige Steher an seinem oberen Ende die Wickelrolle aufnehmen, deren zur Steherachse senkrechte Welle den rohrförmigen Steher oder einen Lagerbock für die Wickelrolle durchsetzt und mit der Wickelwelle antriebsverbunden ist.Usually, the support structure for an awning of the type described comprises at least two posts on which the awning is guyed. Is the gas spring with the cable storage in one of these tubular Stanchion arranged, so there are particularly simple construction conditions, because neither the gas spring nor the cable storage must be accommodated separately. Since the tensioning cable engages the winding roll, which is rotatably connected to the winding shaft, the tubular post can accommodate the winding roll at its upper end, the vertical axis to the vertical axis passing through the tubular post or a bearing block for the winding roll and is drivingly connected to the winding shaft ,

Weg zur Ausführung der ErfindungWay to carry out the invention

Die Spannvorrichtung gemäß den Fig. 1 und 2 weist einen Seilspeicher 1 auf, der zwei Spannrollensätze 2, 3 umfasst. Während der Spannrollensatz 2 in einem rohrförmigen Steher 4 ortsfest gelagert ist, ist der Spannrollensatz 3 auf einer Kopfplatte 5 axial verschiebbar im rohrförmigen Steher 4 angeordnet, und zwar auf der Kolbenstange 6 einer Gasfeder 7, die im Bereich des Spannrollensatzes 2 ortsfest angelenkt ist. Die Anordnung ist dabei so getroffen, dass sowohl der Spannrollensatz 2 als auch die Anlenkachse 8 der Gasfeder 7 in einem Lagereinsatz 9 des rohrförmigen Stehers 4 gehalten sind. Das an der Kopfplatte 5 befestigte Spannseil 10 ist schlingenbildend zwischen den beiden Spannrollensätzen 2 und 3 hin- und hergeführt, wobei das vom Seilspeicher 1 ablaufende Spannseiltrum 11 über eine Umlenkrolle 12 radial zum Steher 4 nach außen geführt ist.The tensioning device according to Fig. 1 and 2 has a cable storage 1, which comprises two sets of tension rollers 2, 3. While the tensioning roller set 2 is stationarily mounted in a tubular upright 4, the tensioning roller set 3 is arranged axially displaceably on a head plate 5 in the tubular upright 4, specifically on the piston rod 6 of a gas spring 7 which is articulated in the area of the tensioning roller set 2 in a stationary manner. The arrangement is made such that both the tensioning roller set 2 and the pivot axis 8 of the gas spring 7 are held in a bearing insert 9 of the tubular post 4. That at the Head plate 5 fastened tensioning cable 10 is looped back and forth between the two sets of tension rollers 2 and 3, wherein the running of the cable storage 1 Spannseiltrum 11 is guided via a guide roller 12 radially to the upright 4 to the outside.

In der Fig. 4 ist ein nicht erfindungsgemäßes Sonnensegel 13 schematisch dargestellt, das entlang einer Teil- oder Faltlinie 14 auf einer Wickelwelle 15 befestigt ist, die zwischen zwei Stehern 16, 17 gehalten ist und mit Hilfe eines innerhalb der Wickelwelle 15 vorgesehenen Motors in an sich bekannter Weise im Aufwickelsinn des Sonnensegels 13 angetrieben werden kann. Die von der Wickelwelle 15 abgekehrten Enden 18 des Sonnensegels 13 sind mit einem Seilzug 19 verbunden, der einerseits über eine Umlenkführung 20 am Spannseiltrum 11 und anderseits über eine Umlenkführung 21 an einem dem Steher 4 bezüglich der Wickelwelle 15 gegenüberliegenden Steher 22 lastabtragend abgestützt ist. Wird somit die Wickelwelle durch den zugehörigen Antriebsmotor freigegeben, so wird das Sonnensegel 13 durch die Kraft der Gasfeder 7 von der Wickelwelle 15 abgezogen und ausgespannt, weil das Spannseiltrum 11 durch das Auseinanderbewegen der beiden Spannrollensätze 2, 3 mit Hilfe der entsprechend vorgespannten Gasfeder 7 in den Seilspeicher 1 eingezogen wird.In the Fig. 4 is a non-inventive sunshade 13 shown schematically, which is secured along a partial or fold line 14 on a winding shaft 15 which is held between two uprights 16, 17 and with the aid of a provided within the winding shaft 15 motor in a conventional manner in the Aufwickelsinn the sun sail 13 can be driven. The remote from the winding shaft 15 ends 18 of the awning 13 are connected to a cable 19, which is supported on the one hand via a deflection guide 20 on Spannseiltrum 11 and on the other hand via a Umlenkführung 21 on a the stayer 4 with respect to the winding shaft 15 opposite uprights 22 load-bearing. Thus, if the winding shaft released by the associated drive motor, the sun sail 13 is withdrawn by the force of the gas spring 7 of the winding shaft 15 and stretched because the Spannseiltrum 11 by the moving apart of the two sets of tension rollers 2, 3 with the aid of the corresponding biased gas spring 7 in the rope storage 1 is fed.

Das nicht erfindungsgemäße Sonnensegel 13 ist in der Fig. 4 in der aufgespannten Stellung gezeigt. Zum Aufwickeln des Sonnensegels 13 wird der Motor der Wickelwelle 15 betätigt, sodass das Sonnensegel 13 entgegen der Spannkraft des Seilspeichers 1 auf die Wickelwelle 14 aufgerollt wird. Der durch die Gasfeder 7 beaufschlagte Seilspeicher 1 hält somit das Sonnensegel 13 in jeder Wickelstellung gespannt. Wird das aufgespannte Sonnensegel 13 durch äußere Kräfte, beispielsweise durch Windkräfte oder durch niederschlagsbedingte Gewichtskräfte, in einem die Spannkraft des Seilspeichers 1 übersteigenden Ausmaß belastet, so wird das Spannseiltrum 11 aus dem Seilspeicher 1 ausgezogen, bis die äußere Belastung die Spannkraft des Seilspeichers 1 wieder unterschreitet. Dies kann durch ein Nachlassen der Windkräfte oder durch ein Abfließen des sich auf dem Sonnensegel 13 sammelnden Niederschlagswassers bedingt sein. Mit dem Nachlassen der äußeren Belastung kehrt somit das Sonnensegel 13 in seine Ausgangslage zurück, wobei die äußere Belastung des Sonnensegels 13 und der lastabtragenden Konstruktion durch die maximale Spannkraft des Seilspeichers 1 beschränkt wird.The non-inventive sunshade 13 is in the Fig. 4 shown in the unfolded position. For winding up the sun sail 13, the motor of the winding shaft 15 is actuated, so that the sun sail 13 is rolled against the clamping force of the cable storage 1 on the winding shaft 14. The acted upon by the gas spring 7 cable storage 1 thus holds the awning 13 stretched in each winding position. If the tensioned sunshade 13 is loaded by external forces, for example by wind forces or precipitation-related weight forces, in an amount exceeding the clamping force of the cable store 1, the tensioning cable run 11 is pulled out of the cable store 1 until the external load falls below the clamping force of the cable store 1 again , This may be due to a decrease in wind forces or by a flow of precipitation water collecting on the awning 13. With the release of the external load thus the awning 13 returns its initial position, the external load of the awning 13 and the load-bearing construction is limited by the maximum clamping force of the cable storage 1.

Nach der Fig. 5 ist erfindungsgemäß die Wickelwelle 15 zwischen dem den Seilspeicher 1 aufnehmenden Steher 4 und dem gegenüberliegenden Steher 22 gelagert, während die Steher 16 und 17 zum Abstützen des an den Enden 18 des Sonnensegels 13 angreifenden Seilzuges 19 über Umlenkführungen 20, 21 dienen. Zur Beaufschlagung des Seilzuges 19 dient ein Antriebsseil 30, das durch einen Motor oder von Hand aus auf eine Wickelwelle 23 aufgewickelt werden kann und über eine Umlenkrolle 24 zur Umlenkführung 20 verläuft, mit der es zugfest verbunden ist.After Fig. 5 According to the invention, the winding shaft 15 between the rope store 1 receiving post 4 and the opposite uprights 22 is supported, while the uprights 16 and 17 serve to support the acting at the ends 18 of the awning 13 cable 19 via deflecting guides 20, 21. To act on the cable 19 is a drive cable 30, which can be wound by a motor or by hand on a winding shaft 23 and a deflection roller 24 extends to the deflection guide 20, with which it is connected tensile strength.

Die Wickelwelle 15 ist mit einer Wickelrolle 25 antriebsverbunden, die auf dem Steher 4 mit dem Seilspeicher 1 gelagert ist, wie dies der Fig. 3 entnommen werden kann. An dieser Wickelrolle 25 greift das vom Seilspeicher 1 ablaufende Spannseiltrum 11 an, sodass die Wickelrolle 25 über das Spannseiltrum 11 durch den federbelasteten Seilspeicher 1 im Abwickelsinn durch ein Drehmoment belastet wird, das jedoch auf die Wickelwelle 15 im Aufwickelsinn des Sonnensegels 13 wirkt, sodass das Sonnensegel 13 über die mit einem im Aufwickelsinn belastete Wickelwelle 15 in der jeweiligen Abziehstellung gehalten wird, die durch das auf der Wickelwelle 23 aufgerollte Antriebsseil 30 bestimmt wird. In diesem Fall ist die Freigabe des Sonnensegels 13 bei einer äußeren Belastung jedoch durch die Abziehlänge des jeweils noch auf der Wickelwelle 15 verbleibenden Sonnensegelwickels beschränkt.The winding shaft 15 is drivingly connected to a winding roller 25 which is mounted on the uprights 4 to the cable storage 1, as is the Fig. 3 can be removed. At this winding roller 25 which runs from the cable storage 1 Spannseiltrum 11 engages, so that the winding roller 25 is loaded via the tensioning cable 11 through the spring-loaded cable storage 1 in the unwinding by a torque, however, acts on the winding shaft 15 in Aufwickelsinn the sun sail 13, so that Awning 13 is held over the winding shaft 15 loaded in the winding sense in the respective peeling position, which is determined by the wound on the winding shaft 23 drive cable 30. In this case, the release of the awning 13 is limited at an external load, however, by the stripping length of each still remaining on the winding shaft 15 sun sail wrapping.

Um einfache Konstruktionsverhältnisse zu schaffen, ist der Lagerbock 26 für die Wickelrolle 25 auf das obere Ende des Stehers 4 aufgesetzt, wobei die Welle 27 der Wickelrolle 25 den Lagerbock 26 durchsetzt und mit der Wickelwelle 15 drehfest verbunden ist. Zu diesem Zweck bildet die Welle 27 der Wickelrolle 25 eine Aufnahmegabel 28 für einen Anschlusssteg 29 der Wickelwelle 15. Die Wickelwelle 15 muss jedoch nicht als starre Welle ausgebildet sein, sondern kann auch aus zwischen Anschlusswellenstummeln gespannten Zugmitteln bestehen, an denen das Sonnensegel 13 entlang einer Falt- oder Teilungslinie 14 befestigt ist, weil es ja lediglich darum geht, das Sonnensegel 13 um einen Kern aufzuwickeln, sei es um eine starre Welle oder um gespannte Zugmittel.To create simple construction conditions, the bearing block 26 is placed on the winding roller 25 on the upper end of the post 4, wherein the shaft 27 of the winding roller 25 passes through the bearing block 26 and rotatably connected to the winding shaft 15. For this purpose, the shaft 27 of the winding roll 25 forms a receiving fork 28 for a connecting web 29 of the winding shaft 15. However, the winding shaft 15 does not have to be designed as a rigid shaft, but can also be tensioned between connecting shaft stubs pulling means exist where the awning 13 is attached along a folding or dividing line 14, because it is only about the awning 13 to wind around a core, be it a rigid shaft or tensioned traction means.
