Spannvorrichtung für ein von einer Wickelwelle abziehbares SonnenseαelClamping device for a solar shaft peelable from a winding shaft
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.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.
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, so daß 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.

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 with the additional return of the cables to the winding shaft and provided for between the returned cables tension devices a significant design effort is connected. In addition, the elastic chucking provided by the tensioning device is sufficient. _ _
nung 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.The cables are not designed to protect the load-bearing structure and the awning from being overloaded by gusts of wind or rain. In addition, the winding shaft with the drive for winding and unwinding of the solar sail is to form sufficiently rigid, resulting in a corresponding limitation of the winding shaft diameter to a limitation of the sun sail size.
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 je nach Einsatz die Voraussetzung mit sich bringt, im Auszieh- oder Aufwickelsinn wirksam zu werden.The invention is therefore the object of a tensioning device for 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 depending on the application brings with it the prerequisite to be effective in the withdrawal or Aufwickelsinn ,
Die Erfindung löst die gestellte Aufgabe dadurch, daß die Feder als Gasfeder zum Spannen eines 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 solves the problem set by the fact that the spring is designed as a gas spring for tensioning a cable storage, which has two with the help of the gas spring mutually adjustable clamping roller sets for looping between the sets of tension rollers reciprocating tensioning cable.
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 rope 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 rope storage 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 are easily adapted to the respective size of the exciting awning can. _
Dies gilt für einen Einsatz der Spannvorrichtung sowohl zum Abziehen des Sonnensegels von der Wickelwelle als auch zum Aufwickeln. Während zum Abziehen das aus dem Seilspeicher ausgezogene Spannseil an einem Seilzug zum Abziehen des Sonnensegels angreift und unter einer federnden Abspannung des Sonnensegels in den Seilspeicher eingezogen wird, kann das Spannseil zum Aufwickeln des Sonnensegels an einer mit der Wickelwelle antriebsverbundenen Wickelrolle befestigt sein, 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 abgezogen werden, 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, so daß Sonnensegel auch mit größeren Segelflächen vorteilhaft abgespannt werden können.This applies to a use of the tensioning device both for removing the awning from the winding shaft and for winding. While pulling the pulled-out from the rope store tensioning cable to a cable pull for removing the awning and is fed under a resilient bracing of the awning in the cable storage, the tensioning cable for winding the sun sail can be attached to a drive connected to the winding shaft winding roller, which therefore with acting in a Aufwickelsinn torque is applied. A for removing the awning provided by the winding shaft drive, which is to be connected to an attacking the sun sail to pull off the awning, therefore, the awning must be deducted against the restraint caused by the rope storage, which allows the required resilient bracing of the awning on the winding shaft , And even if taken from a rigid winding shaft distance and a winding shaft is used in the form of a tensioned between stub sheave cable, so that sun sails can be tapped advantageous with larger sail areas.
Mit dem Abziehen des Sonnensegels von einer Wickelwelle mit Hilfe des durch eine Gasfeder im Sinne eines Einziehens des Spannseils vorgespannten Seilspeichers ergibt sich darüber hinaus der besondere Vorteil, daß die Tragkonstruktion zur Abstützung des Sonnensegels und das Sonnensegel selbst vor einer Überlastung beispielsweise durch einen Windangriff geschützt ist, weil bei einer die federnden Abspannkräfte durch die Gasfeder übersteigenden Segelbelastung das Spannseil aus dem Seilspeicher ausgezogen wird und folglich das Sonnensegel dem Winddruck ausweichen kann, bis das Sonnensegel beim Nachlassen der Windkräfte wieder in die Ausgangslage ausgespannt wird. Da das Spannseil zumindest um die Abziehlänge des Sonnensegels von der Wickelwelle aus dem Seilspeicher unter der federnden Rückzugskraft der Gasfeder aus dem Seilspeicher ausgezogen werden kann, wird das Sonnensegel auch bei einer Aufnahme von Regenwasser ausweichen, bis das Re- _With the removal of the awning from a winding shaft by means of biased by a gas spring in the sense of retraction of the tension cable rope storage also results in the particular advantage that the support structure for supporting the awning and the awning itself is protected against overload, for example by a wind attack because at a spring tension exceeding the resilient Abspannkräfte by the gas spring, the tension cable is pulled out of the cable storage and consequently the sun can avoid the wind pressure until the awning is relaxed when the wind forces decrease in the starting position. Since the tensioning cable can be pulled out of the cable store at least by the stripping length of the awning from the winding shaft out of the cable storage under the resilient retraction force of the gas spring, the awning will also escape when rainwater is taken up until the _
genwasser vom Sonnensegel abrinnt und wieder in die abgespannte Ausgangslage zurückkehrt.genwasser from the awning runs off and returns to the relaxed starting position.
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. Es ist lediglich für eine entsprechende Führung des Spannseiles zur Verbindung mit dem am Sonnensegel angreifenden Seilzug zu sorgen. Zu diesem Zweck kann mit einem geringen Konstruktionsaufwand am oberen Ende des rohrförmigen Stehers eine Umlenkrolle für das Spannseil mit einer zur Steherachse senkrechten Drehachse vorgesehen sein. Für den Fall, daß das Spannseil an einer 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. If the gas spring is arranged with the cable storage in one of these tubular uprights, so there are particularly simple design conditions, because neither the gas spring nor the cable storage must be accommodated separately. It is only to provide for a corresponding guidance of the tensioning cable for connection to the awning acting on the cable. For this purpose, a deflection roller for the tensioning cable can be provided with a vertical axis of rotation to the vertical axis with a small design effort at the upper end of the tubular stanchion. In the event that the tensioning cable engages a winding roll, which is rotatably connected to the winding shaft, the tubular stand can record at its upper end the winding roll whose perpendicular to the vertical axis shaft passes through the tubular post or a bearing block for the winding roll and the winding shaft is drivingly connected.

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 FIGS. 1 and 2 has a cable storage 1 which comprises two tensioning roller sets 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. The tensioning cable 10 fastened to the top plate 5 is looped back and forth between the two tensioning roller sets 2 and 3, wherein the tensioning cable run 11 running from the cable storage 1 is led radially outward to the upright 4 via a deflection roller 12.
In der Fig. 4 ist ein 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 Auseinander- bewegen der beiden Spannrollensätze 2, 3 mit Hilfe der entsprechend vorgespannten Gasfeder 7 in den Seilspeicher 1 eingezogen wird.In Fig. 4, an awning 13 is shown schematically, which is secured along a partial or fold line 14 on a winding shaft 15 which is held between two stators 16, 17 and with the aid of an envisaged within the winding shaft 15 motor in per se Way in the Aufwickelsinn of the awning 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 is released by the associated drive motor, then the sun sail 13 is pulled off and unclamped by the winding shaft 15 by the force of the gas spring 7, because the tensioning cable run 11 is interrupted by the disengagement. move the two sets of tension rollers 2, 3 with the aid of the correspondingly biased gas spring 7 is fed into the cable storage 1.
Das Sonnensegel 13 ist in der Fig. 4 in der aufgespannten Stellung gezeigt. Zum Aufwickeln des Sonnensegels 13 wird der Motor der Wickelwelle 15 betätigt, so daß 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 awning 13 is shown in Fig. 4 in the clamped position. For winding 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 to its original 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 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 22, 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.According to Fig. 5, the winding shaft 15 is mounted between the cable storage 1 receiving post 4 and the opposite uprights 22, 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 22, 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 ablaufen- de Spannseiltrum 11 an, so daß 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, so daß 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 22 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 upright 4 with the cable storage 1, as shown in FIG. 3 can be removed. At this winding roller 25, the rope storage 1 runs off. de Spannseiltrum 11, so that the winding roller 25 is charged via the Spannseiltrum 11 by 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 the awning 13 via the with an im Winding sense loaded winding shaft 15 is held in the respective Abziehstellung, which is determined by the wound on the winding shaft 23 drive cable 22. 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 FaIt- 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 roller 25 forms a receiving fork 28 for a connecting web 29 of the winding shaft 15. However, the winding shaft 15 need not be designed as a rigid shaft, but may also consist of tensioned between connecting shaft stubs pulling means in which the awning 13 along a FaIt- or dividing line 14 is attached, because it is only about the sun sail 13 to wind around a core, be it a rigid shaft or tensioned traction means.
