Description

Die Erfindung betrifft eine Roll-Markise mit einer Tuchwelle, einem mit seinem einen Ende mit der Tuchwelle verbundenen, auf der Tuchwelle auf und abwickelbaren Tuch, wenigstens einem mit seinem einen Ende mit dem freien Ende des Tuchs verbundenen Zugseil, wenigstens einem Mast, und einer am Mast angeordneten, eine Seiltrommel aufweisende Seilwinde, die mit dem anderen Ende des Zugseils verbunden und zum Auf und Abwickeln des Zugseils eingerichtet ist.The invention relates to a roll-awning with a fabric shaft, a connected at one end to the fabric shaft, on the fabric shaft and unwound cloth, at least one with its one end connected to the free end of the cloth pull rope, at least one mast, and a arranged on the mast, a cable drum having winch, which is connected to the other end of the hauling rope and adapted for winding and unwinding of the hauling rope.

Eine derartig ausgebildete Roll-Markise ist beispielsweise aus der WO 2015/022 324 A1 bekannt.Such trained awning is for example from the WO 2015/022 324 A1 known.

Die aus der WO 2015/022 324 A1 bekannte Roll-Markise weist insbesondere ein Zugseil auf, das von einer Spanneinrichtung mit einer voreingestellten Sollspannung beaufschlagt wird, wobei die Spanneinrichtung einen Seilvorrat speichert, der bei einer die Sollspannung überschreitenden Zugspannung im Zugseil zur Verlängerung der wirksamen Länge des Zugseiles vermindert und der bei einer die Sollspannung unterschreitenden Zugspannung um Zugseil zur Verkürzung der wirksamen Länge des Zugseiles vergrößert wird. Speziell bedient sich die WO 2015/022 324 A1 hierzu einer auf einen die Seilspannung regulierenden Antriebsmotor wirkenden Spannkraftvergleichseinrichtung.The from the WO 2015/022 324 A1 known roller awning has in particular a pull rope, which is acted upon by a tensioning device with a preset target voltage, wherein the tensioning device stores a cable supply, which reduces at a tension exceeding the target tension in the traction cable to extend the effective length of the traction cable and at a the Target tension is lower tension to pull rope to shorten the effective length of the traction cable is increased. Specially used the WO 2015/022 324 A1 for this purpose, a clamping force comparison device acting on a drive motor regulating the cable tension.

Gegenüber der DE 10 2013 104 777 A1 besteht beim erst genannten Stand der Technik der Vorteil eines kompakteren Aufbaus, bei dem auf großvolumige Gewichte verzichtet und damit die Baugröße der Spanneinrichtung verringert werden kann.Opposite the DE 10 2013 104 777 A1 consists in the first-mentioned prior art, the advantage of a more compact structure, dispensed with bulky weights and thus the size of the clamping device can be reduced.

Nichtsdestotrotz sind die aus dem Stand der Technik bekannten Roll-Markisen hinsichtlich ihres Aufbaus und ihrer Bedienung recht aufwändig und wartungsintensiv. Darüber hinaus erscheint eine permanente Ansteuerung eines Antriebsmotors störend und auch zu träge, um plötzlich auftretenden Windlasten entgegen zu wirken.Nevertheless, the known from the prior art rolling awnings are quite complex and maintenance-intensive in terms of their structure and their operation. In addition, a permanent control of a drive motor appears disturbing and too sluggish to counteract sudden wind loads.

Aufgabe der Erfindung ist es daher, eine Roll-Markise mit einfachem und robusten Aufbau bereitzustellen, die auch plötzlich bei plötzlich auftretenden Windlasten die Seilspannung konstant halten kann.The object of the invention is therefore to provide a roll-awning with a simple and robust design that can hold the rope tension also suddenly in sudden wind loads.

Diese Aufgabe wird erfindungsgemäß durch die Roll-Markise mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.This object is achieved by the roll-awning with the features of claim 1. The subclaims reflect advantageous embodiments of the invention.

Die Erfindung betrifft also eine Roll-Markise mit einer Tuchwelle, einem mit seinem einen Ende mit der Tuchwelle verbundenen, auf der Tuchwelle auf- und abwickelbaren Tuch, wenigstens einem mit seinem einen Ende mit dem freien Ende des Tuchs verbundenen Zugseil, wenigstens einem Mast, und einer am Mast angeordneten, eine Seiltrommel aufweisende Seilwinde, die mit dem anderen Ende des Zugseils verbunden und zum Auf- und Abwickeln des Zugseils eingerichtet ist, wobei die Seilwinde eine ein Drehmoment auf die Seiltrommel ausübende Feder zur Kompensation von auf das Zugseil und/oder das Segeltuch von der Federspannung abweichenden Lasten aufweist.The invention thus relates to a roller awning with a roller tube, one at its one end connected to the roller tube, on the tissue shaft up and unwindable cloth, at least one with its one end connected to the free end of the cloth pull rope, at least one mast, and arranged on the mast, a cable drum having winch, which is connected to the other end of the hauling rope and adapted for winding and unwinding of the hawser, wherein the winch a torque on the rope drum performing spring to compensate for the pull rope and / or the canvas has loads deviating from the spring tension.

Die Feder (auch Tragfeder genannt), die einerseits mit der Welle der Seilwinde (auch als Federraste bezeichnet) und andererseits mit der Seiltrommel verbunden ist, ist derart vorgespannt, dass das Zugseil im Betrieb mit dem Tuch über den ganzen Auszugsbereich eine im Wesentlichen gleichbleibende Spannung aufweist. Die Feder wirkt also auf die Trommel und diese wiederum auf das Seil, welches dadurch unter Zugspannung steht. Somit übt dann das Seil auf das Segeltuch eine Zugspannung aus, die bei Windlast aber - bedingt durch die Feder - nachgeben kann und dadurch das Segeltuch etc. vor Beschädigungen schützt.The spring (also called the suspension spring), which is connected on the one hand with the shaft of the winch (also referred to as spring catch) and on the other hand with the cable drum, is biased such that the pull rope during operation with the cloth over the entire extension region a substantially constant voltage having. The spring thus acts on the drum and this in turn on the rope, which is thereby under tension. Thus, then the rope exerts on the canvas a tensile stress, but in wind load - due to the spring - can yield and thereby protects the canvas etc. from damage.

Die Seilwinde ist erfindungsgemäß als ein eine konische Seiltrommel aufweisender Balancer ausgebildet. Die Ausbildung der Seiltrommel mit einer konischen Form garantiert die über den Auszugsbereich gleichmäßig bleibende Federspannung.The winch is inventively designed as a conical cable drum exhibiting balancer. The formation of the cable drum with a conical shape guarantees the spring tension that remains uniform over the extension area.

Durch die Vorspannung der Feder des Balancers, der üblicherweise als Gewichtsausgleicher verwendet wird, wirkt ein Anfangsdrehmoment und eine Rückzugskraft. Wird das Zugseil ausgezogen erhöht sich die Federspannung und somit das Drehmoment. Dabei werden der Drehmomentanstieg und die daraus resultierende Erhöhung der Rückzugskraft jedoch über den als konische Seiltrommel ausgebildeten variablen Lasthebels ausgeglichen.By biasing the spring of the balancer, which is commonly used as a counterbalance, acts an initial torque and a retraction force. If the pull rope pulled out increases the spring tension and thus the torque. Here are the Torque increase and the resulting increase in the retraction force, however, balanced over the designed as a conical cable drum variable load lever.

Der Vorteil bei der Ausgestaltung des Erfindungsgegenstands mit einem Balancer liegt darin, dass der Balancer eine über den gesamten Seilauszug nahezu gleichbleibende Rückzugskraft bewirkt. Dadurch werden die auf die Tuchwelle und das Mauerwerk, an dem die Tuchwelle üblicherweise befestigt ist, wirkenden Kräfte minimiert, sodass insbesondere großflächig abschattende Markisen geschaffen werden können.The advantage of the embodiment of the subject invention with a balancer is that the balancer causes a nearly constant retraction force over the entire cable pullout. As a result, the forces acting on the fabric shaft and the masonry, to which the fabric shaft is usually attached, acting forces minimized, so that in particular shading awnings can be created over a large area.

Zum Antrieb der Seilwinde ist insbesondere ein auf die Welle der Seilwinde wirkender Elektromotor vorgesehen.To drive the winch in particular an acting on the shaft of the winch electric motor is provided.

Besonders vorteilhaft kann die Roll-Markise ausgestaltet werden, wenn ein am Mast angeordnetes, zwischen der Seilwinde und dem Tuch angeordnetes Umlenkmittel zum Umlenken des Zugseils aus einer vertikalen Ebene in eine horizontale Ebene vorgesehen ist. In diesem Fall kann die Seilwinde in das Innere des bevorzugt als Hohlkörper ausgebildeten Masts verlagert werden, sodass ein kompakter, vor äußeren Witterungseinflüssen geschützter und ästhetisch schlichter Aufbau erreicht werden kann.Particularly advantageously, the roll-awning can be configured when a arranged on the mast, arranged between the winch and the cloth deflecting means for deflecting the pull rope from a vertical plane is provided in a horizontal plane. In this case, the winch can be displaced into the interior of the mast, which is preferably designed as a hollow body, so that a compact, aesthetically simple structure protected from external weather influences can be achieved.

Insbesondere ist das Umlenkmittel in seiner vertikalen Position am Mast verstellbar, besonders bevorzugt verfahrbar eingerichtet, sodass die Neigung des Tuchs, z.B. zum Ablauf von Regenwasser, speziell stufenlos eingestellt werden kann.In particular, the deflection means is adjustable in its vertical position on the mast, particularly preferably arranged movable so that the inclination of the cloth, e.g. for drainage of rainwater, especially steplessly adjustable.

Um eine gleichmäßige Kraftübertragung vom Zugseil auf das Tuch zu gewährleisten, weist das mit dem freien Ende des Tuchs verbundene Ende des Zugseils eine Umlenkrolle auf, sodass an der Verbindung zwischen Zugseil und Tuch auftretende Querkräfte materialschonend umgelenkt werden können.In order to ensure a uniform power transmission from the pull rope to the cloth, the connected to the free end of the cloth end of the pull rope on a pulley so that occurring at the connection between the pull rope and cloth lateral forces can be deflected gently.

Insbesondere weist nach einer weiter bevorzugten Ausgestaltung das freie Ende des Tuchs ein mit seinen beiden Enden mit dem Tuch verbundenes Spannseil auf, das in der Umlenkrolle des Zugseils geführt ist.In particular, according to a further preferred embodiment, the free end of the cloth on one with its two ends connected to the cloth tensioning cable, which is guided in the deflection roller of the pull rope.

Es bietet sich zur Verstärkung des Tuchs zugleich an, das freie Ende des Tuchs durch eine mit dem freien Ende des Tuchs verbundene Abschlussleiste auszubilden.It also lends itself to reinforcing the cloth to form the free end of the cloth by a connected to the free end of the cloth end bar.

Schließlich ist es auch vorteilhaft, das Tuch an seinen Seiten konkav und insbesondere mit Textil- oder Kunststoffstreifen verstärkt auszubilden, sodass das Tuch über seine Breite und Länge eine gewisse Eigenspannung aufweist, die auch das korrekte Auf- und Abrollen des Tuchs auf der Tuchwelle unterstützt.Finally, it is also advantageous to concave the cloth on its sides and in particular reinforced with textile or plastic strip, so that the cloth over its width and length has a certain residual stress, which also supports the correct winding and unwinding of the cloth on the fabric shaft.

Die Erfindung eignet sich insbesondere für textile Sonnenschutzanlagen, die insbesondere plötzlich auftretenden Winden stark ausgesetzt sind. Bei Markisen, Sonnensegeln oder sonstigen Konstruktionen werden die textilen Tücher von dem Wind beansprucht, die Tücher bewegen sich und leiten die auftretenden Kräfte an die Befestigungspunkte weiter. Je nach Windstärke können somit Schäden an den Befestigungspunkten wie z.B. Mauerwerk auftreten.The invention is particularly suitable for textile sun protection systems, which are particularly exposed to sudden winds. In awnings, sun sails or other constructions, the textile cloths are stressed by the wind, the cloths move and forward the forces occurring to the attachment points. Depending on the wind force damage to the attachment points such. Masonry occur.

Dieses wird durch die vorliegende Erfindung vermieden oder zumindest stark vermindert.This is avoided or at least greatly reduced by the present invention.

Liegt das Tuch komplett auf der Wickelwelle, ist die Federspannung maximal gespannt, sodass ein reibungsloses Herauslaufen des Tuches gewährleistet ist.If the cloth lies completely on the winding shaft, the spring tension is maximally tensioned, so that a smooth running out of the cloth is guaranteed.

Ist das Tuch zur Hälfte von der Wickelwelle abgewickelt und zur Hälfte ausgefahren, sodass ein Teilbereich des zu beschattenden Bereiches beschattet ist, hält die Federspannung das Tuch auf Spannung.If the cloth is half unwound from the winding shaft and half extended so that a portion of the area to be shaded is shaded, the spring tension keeps the cloth on tension.

Auch wenn das Tuch die gesamt zu beschattende Fläche beschattet und dazu vollständig von der Tuchwelle abgewickelt ist, wird das Tuch weiterhin mit der gleichen Zugkraft wie in den anderen Zuständen auf Spannung gehalten.Even if the cloth shadows the entire surface to be shaded and is completely unwound from the cloth shaft, the cloth will continue to be tensioned with the same pulling force as in the other states.

Durch die gleiche Zugkraft der Federn in jedem Zustand werden auftretende Winde direkt von den Federn aufgenommen, so dass starke Windkräfte nicht mehr auf das Mauerwerk abgeleitet werden. Vielmehr geben die Federn insoweit nach, dass sich, sobald sich der Wind im Stoff verfängt, die Kräfte aufheben und sich selber eliminieren. Somit ist gewährleistet, dass die Befestigungspunkte am Mauerwerk keine Kräfte mehr aufnehmen müssen und somit keinen Schaden mehr verursachen. Ein Zerstören des Stoffes oder gar der Anlage ist somit auch praktisch ausgeschlossen, da die Federn das gesamte aufgewickelte Seil wieder abgeben könnten.By the same pulling force of the springs in each state occurring winds are absorbed directly by the springs, so that strong wind forces are no longer dissipated to the masonry. Rather, the springs give way to the extent that, as soon as the wind caught in the fabric, the forces cancel and eliminate themselves. This ensures that the attachment points on masonry no longer need to absorb forces and thus cause no more damage. Destroying the substance or even the system is thus practically impossible since the springs could release the entire wound rope again.

Da es jedoch für die permanente Tuchspannung einer über den Auszugsbereich der Markise annähernd konstanten Federspannung bedarf, besteht bei einem Seilbruch aufgrund der Vorspannung des Seils die Gefahr der Verletzung von Personen und/oder von Sachschäden,.However, since it requires for the permanent fabric tension over the extension range of the awning approximately constant spring tension, there is a risk of injury to persons and / or material damage in a cable break due to the bias of the rope.

Erfindungsgemäß wird daher auch eine als Fliehkraftbremse wirkende Sicherheitsbremse vorgeschlagen, die die durch die Vorspannung bewirkte Rotation der Seilwinde bei einem Seilbruch stoppt. Dadurch werden ein abruptes und unkontrolliertes Einziehen des Seils verhindert und Personen und Gegenstände vor einem durch das rückschlagende Seil verursachten Schaden bewahrt.Therefore, according to the invention, a safety brake acting as a centrifugal brake is proposed, which stops the rotation of the cable winch caused by the prestressing in the event of a cable break. This prevents abrupt and uncontrolled pulling in of the rope and protects persons and objects from damage caused by the kickback rope.

Die Roll-Markise 10 weist demnach eine Tuchwelle 20, ein mit seinem einen Ende mit der Tuchwelle 20 verbundenes, auf der Tuchwelle 20 auf- und abwickelbares Tuch 30 und zwei mit ihrem einen Ende mit dem freien Ende des Tuchs 30 verbundene Zugseile 40 auf.Accordingly, the roller awning 10 has a cloth shaft 20, a cloth 30 which can be wound up and unwound on the cloth shaft 20 and has one end connected to the cloth shaft 20, and two tension cables 40 connected at one end to the free end of the cloth 30.

Jedes Zugseil 40 ist mit seinem anderen Ende mit einem Mast 50 verbunden, der jeweils eine am Mast 50 angeordnete, eine Seiltrommel aufweisende Seilwinde aufnimmt, wobei die Seilwinde eine ein Drehmoment auf die Seiltrommel ausübende Feder zur Kompensation von auf das Zugseil und/oder das Segeltuch von der Federspannung abweichenden Lasten aufweist.Each pull cord 40 is connected at its other end to a mast 50, each receiving a mast 50, a cable drum having cable winch, wherein the winch a torque on the cable drum performing spring to compensate for the pull rope and / or the canvas Having loads deviating from the spring tension.

Insbesondere ist die Seilwinde als der in Fig. 2 gezeigte Balancer ausgebildet.In particular, the winch is considered the one in Fig. 2 shown balancer formed.

Die als Balancer ausgebildete Seilwinde 60, die beispielsweise jeweils in einem der in Fig. 1 Masten verdeckt angeordnet ist, weist eine das Zugseil 40 aufnehmende konische Seiltrommel 62 auf. Die Seiltrommel 62 ist um eine motorisch angetriebene Welle 64 drehbar angeordnet, wobei eine Feder 66 vorgesehen ist, deren eines Ende mit der Welle 64 und deren anderes Ende mit der Seiltrommel 62 verbunden ist, sodass ein Drehmoment auf die Seiltrommel 62 gebracht und das Zugseil 40 vorgespannt wird.Trained as a balancer winch 60, for example, each in one of in Fig. 1 Masts is arranged concealed, has a pull rope 40 receiving conical cable drum 62. The cable drum 62 is rotatably mounted about a motor-driven shaft 64, wherein a spring 66 is provided, one end of which is connected to the shaft 64 and the other end of the cable drum 62, so that a torque placed on the cable drum 62 and the traction cable 40th is biased.

Weiter zeigt Fig. 3 ein perspektivisches Detail des in Fig. 1 dargestellten Ausführungsbeispiels im Bereich der Anbindung von Zugseil 40 und Spannseil 44. Um in der horizontalen Ebene eine gleichmäßige Kraftübertragung vom Zugseil 40 auf das Tuch 30 zu gewährleisten, weist das mit dem freien Ende des Tuchs 30 verbundene Ende des Zugseils 40 eine Umlenkrolle 42 auf. Durch diese Maßnahme werden zwischen Zugseil 40 und Tuch 30 auftretende Querkräfte, die z.B. durch unter das Tuch greifende Winde verursacht werden, materialschonend umgelenkt.Next shows Fig. 3 a perspective detail of the in Fig. 1 In order to ensure a uniform force transmission from the pulling cable 40 to the cloth 30 in the horizontal plane, the end of the pulling cable 40 connected to the free end of the cloth 30 has a deflection roller 42. As a result of this measure, transverse forces occurring between the traction cable 40 and the cloth 30, which are caused, for example, by winds passing under the cloth, are deflected in a manner that protects the material.

Schließlich zeigt Fig. 4 eine besonders bevorzugte Ausgestaltung der Seilwinde mit einer Sicherheitsbremse.Finally shows Fig. 4 a particularly preferred embodiment of the winch with a safety brake.

Wie oben dargestellt, bedarf es für die permanente Tuchspannung einer über den Auszugsbereich der Markise annähernd konstanten Federspannung. Dabei ist es egal, ob die Markise ein- oder ausgefahren ist - es besteht immer eine (Vor-)Spannung des Seils.As described above, it requires a constant spring tension for the permanent cloth tension over the extension area of the awning. It does not matter whether the awning is extended or retracted - there is always a (pre-) tension of the rope.

Sollte nun einmal das Seil reißen, besteht aufgrund der Vorspannung des Seils die Gefahr der Verletzung von Personen und/oder von Sachschäden. Ganz extrem ist es, wenn die Federspannung maximal ist und das Seil in Tuchnähe reißt. Das Seil - meistens aus Stahl - kann somit frei um sich schlagen bis die Feder sich entspannt hat.Should the rope break, there is a risk of personal injury and / or property damage due to the tension of the rope. It is extremely extreme when the spring tension is maximum and the rope tears near the fabric. The rope - mostly made of steel - can thus beat around itself until the spring has relaxed.

Bevorzugt wird daher eine als Fliehkraftbremse wirkende Sicherheitsbremse vorgeschlagen.Preferably, therefore, acting as a centrifugal brake safety brake is proposed.

Wie Fig. 4 zeigt, sind an der Federzugtrommel 62 Sicherungselemente 70 vorgesehen, die aufgrund der Schwerkraft und bei erhöhter Umdrehungsgeschwindigkeit derart ausscheren, dass diese sich an einem speziell dafür vorgesehenen ortfesten Widerlager 80 verkanten. Dieses Widerlager kann beispielsweise der die Trommel 62 drehbar lagernde Fuß sein.As Fig. 4 shows, 62 fuse elements 70 are provided on the Federzugtrommel, which ausscheren due to gravity and at increased rotational speed such that they tilt at a specially provided ortfesten abutment 80. This abutment may be, for example, the drum 62 rotatably supporting foot.

Die normale Rotationsgeschwindigkeit gibt üblicherweise der Motor der Anlage vor. Bei normaler Rotationsgeschwindigkeit befinden sich die Sicherungselemente 70 im Ruhezustand und werden bei Rotation nicht mit dem Widerlager 80 in Eingriff gebracht. Erst beim Seilbruch hat die Feder 66 keinen Gegenzug mehr und will sich so schnell wie möglich entspannen. Dabei kommt es zu einer erhöhten Umdrehungsgeschwindigkeit der Federtrommel 62 und die Fliehkraftbremse setzt ein.The normal rotational speed is usually dictated by the engine of the plant. At normal rotational speed, the securing elements 70 are at rest and are not engaged with the abutment 80 during rotation. Only when the cable break the spring 66 has no counter-pull and wants to relax as quickly as possible. This results in an increased rotational speed of the spring drum 62 and the centrifugal brake begins.
