Abstract

The securing members (26) prevent the drop bar (14) in its lower end position moving in the inward direction. The guide components (18) are formed as wire cables or spokes, which extend as far as beneath the lower end position of the drop bar. Hollow components (22) are fixed at the ends (16) of the drop bar. They encompass the guide components and with their lower ends (24) in the lower end position of the drop bar work in conjunction with the securing members. At the lower ends of the hollow components, plate or disc-shaped widened formations are provided, which work in conjunction with the securing members. The hollow components are hoses, casings or tubes.

Description

Die Erfindung befaßt sich mit einem Sonnenschutzbehang mit einem Fallstab, dessen Enden an seitlichen Führungselementen geführt sind, und Arretiergliedern, die an den unteren Enden der Führungselemente angeordnet sind und den Fallstab in seiner unteren Endposition an einer Bewegung in Einfahrrichtung hindern.The invention relates to a sunshade curtain with a drop rod, the ends of which are guided on lateral guide elements, and locking members, which are arranged at the lower ends of the guide elements and prevent the drop rod in its lower end position from moving in the direction of entry.

Bei außenliegenden Sonnenschutzbehängen stellt deren Windstabilität ein erhebliches Problem dar. Bedingt durch die große Angriffsfläche des Sonnenschutzbehangs kommt es unter dem sich schnell ändernden Winddruck zu dynamischen Bewegungen des durch seine Gewichtskraft den Behang spannenden Endstabs. Neben der starken Geräuschentwicklung kann es dabei auch zu Beschädigungen des Behangs kommen. Die auch heute noch weit verbreitete Lösung, den Behang bereits bei schwachem Wind einzufahren, ist unbefriedigend, weil die Sonneneinstrahlung selbst bei Wind stark sein kann. Auch die Beschwerung des meist hohlen Fallstabes mittels eingeschobener Gewichte vermochte das Problem nicht zufriedenstellend zu lösen. Es wurde deshalb bereits vorgeschlagen, den Fallstab in bestimmten Positionen durch Arretierglieder formschlüssig an einer Aufwärtsbewegung zu hindern. Eine zustätzliche Straffung des Behangs wird durch einen Arretiermechanismus gemäß Patentanmeldung 195 36 959.9 sichergestellt, der den Behang mit Hilfe von Federelementen zusätzlich vorspannt.In the case of external sun protection curtains, their wind stability is a considerable problem. Due to the large contact surface of the sun protection curtain, the rapidly changing wind pressure leads to dynamic movements of the end rod which excites the curtain due to its weight. In addition to the strong noise, the curtain can also be damaged. The solution, which is still widespread today, of retracting the curtain even when the wind is weak is unsatisfactory because the solar radiation can be strong even in wind. Even the weighting of the mostly hollow drop bar by means of inserted weights was unable to solve the problem satisfactorily. It has therefore already been proposed to positively prevent the drop rod from moving upward in certain positions by means of locking members. An additional tightening of the curtain is ensured by a locking mechanism according to patent application 195 36 959.9, which additionally pretensions the curtain with the aid of spring elements.

Wenn die Arretiervorrichtungen in den Nuten seitlicher Führungsschienen festgeklemmt werden können, sind sie in ihrer vertikalen Lage einstellbar. Dagegen ist bei Sonnenschutzanlagen, deren seitliche Führungselemente als Drahtseile oder -speichen ausgebildet sind, aus Stabilitäts-gründen eine Befestigung der Arretierglieder nicht in beliebiger Höhe am Seil bzw. der Speiche, sondern nur an den unteren Haltewinkeln der Seile bzw. Speichen möglich. Ein vertikaler Einstellbereich, der z.B. zum Ausgleich von Fertigungstoleranzen nötig sein kann, steht dann nur in sehr kleinem Rahmen zur Verfügung.If the locking devices can be clamped in the grooves of the side guide rails, they can be adjusted in their vertical position. In contrast, in sun protection systems, the lateral guide elements as wire ropes or spokes are formed, for reasons of stability, the locking members cannot be attached to the rope or the spoke at any height, but only to the lower brackets of the ropes or spokes. A vertical setting range, which may be necessary to compensate for manufacturing tolerances, for example, is then only available on a very small scale.

Zudem liegen bei derartigen Sonnenschutzanlagen die Befestigungsorgane der Seile bzw. Speichen aus optischen oder auch befestigungstechnischen Gründen in der Regel ein ganzes Stück unterhalb der Endposition des Fallstabes. Herkömmliche Lösungen zu dessen Arretierung mit Hilfe an den unteren Befestigungsorganen der Führungselemente angebrachter Arretierglieder scheiden daher aus.In addition, in the case of such sun protection systems, the fastening members of the ropes or spokes are generally quite a bit below the end position of the drop rod for optical or fastening reasons. Conventional solutions for locking it with the aid of locking members attached to the lower fastening members of the guide elements are therefore ruled out.

Die Aufgabe der Erfindung besteht darin, einen Sonnenschutzbehang zu schaffen, bei dem auch mit Seilen oder Speichen als Führungselementen der Fallstab mit in der Höhe korrigierbarer Endposition verrieget werden kann.The object of the invention is to provide a sun protection curtain in which the drop rod can also be locked with a height-correctable end position with ropes or spokes as guide elements.

Erfindungsgemäß wird die Aufgabe durch einen Sonnenschutzbehang der eingangs genannten Art, bei welchem die Führungselemente als Drahtseile oder -speichen ausgebildet sind, die sich bis unterhalb der unteren Endposition des Fallstabes erstrecken, dadurch gelöst, daß an den Fallstabenden Hohlelemente befestigt sind, welche die Führungselemente umfassen und mit ihren unteren Enden in der unteren Endposition des Fallstabes mit den Arretiergliedern zusammenwirken.According to the invention, the object is achieved by a sunshade curtain of the type mentioned, in which the guide elements are designed as wire ropes or spokes that extend below the lower end position of the drop rod, in that hollow elements are fastened to the drop rod, which comprise the guide elements and cooperate with their lower ends in the lower end position of the drop rod with the locking members.

Mit Hilfe der Hohlelemente ist es möglich, den sich ggf. mit verhältnismäßig großem Zwischenabstand oberhalb der Arretierglieder befindenden Fallstab auch unter Anwendung von Zugkräften zu arretieren. Die Arretierstellung des Fallstabes, d.h. seine untere Endposition, wird durch die Länge der Hohlelemente festgelegt, womit auch einseitig ein vertikaler Ausgleich möglich ist.With the help of the hollow elements, it is possible to also use the drop rod, which may be located above the locking members with a relatively large spacing, using To lock tensile forces. The locking position of the drop rod, ie its lower end position, is determined by the length of the hollow elements, so that vertical compensation is also possible on one side.

Vorzugsweise sind an den unteren Enden der Hohlelemente teller- oder scheibenförmige Erweiterungen vorgesehen, die mit den Arretiergliedern zusammenwirken. Mit Hilfe dieser Erweiterungen ist eine besonders sichere Arretierung des Fallstabes möglich. Die Erweiterungen gestatten auch, beispielsweise unter Verwendung der in der Patentanmeldung 195 36 959.9 beschriebenen Arretierglieder, Zugkräfte in den Behang einzuleiten.Preferably, plate-shaped or disk-shaped extensions are provided at the lower ends of the hollow elements, which cooperate with the locking members. With the help of these extensions, a particularly secure locking of the drop rod is possible. The extensions also allow tensile forces to be introduced into the curtain, for example using the locking members described in patent application 195 36 959.9.

In bevorzugter Ausgestaltung der Erfindung sind die Hohlelemente Hülsen oder Rohre, die an den Fallstabenden winkelstarr befestigt sind. Gegenüber der grundsätzlich ebenfalls möglichen Verwendung von Schläuchen als Hohlelemente bieten derartig befestigte Hülsen oder Rohre den Vorteil, daß sie die wirksame Führungslänge des Fallstabes an den Führungselementen erhöhen. Der Fallstab kann nicht mehr verkanten und läßt sich nur noch parallel zu den Führungselementen verschieben. Insbesondere während des Verfahrens, d.h. bei gelösten Arretiergliedern, sorgt diese verbesserte Fallstabführung für eine geringere Windempfindlichkeit.In a preferred embodiment of the invention, the hollow elements are sleeves or tubes which are fixed at a fixed angle to the ends of the drop rods. Compared to the basically also possible use of hoses as hollow elements, sleeves or pipes fastened in this way offer the advantage that they increase the effective guide length of the drop rod on the guide elements. The drop rod can no longer tilt and can only be moved parallel to the guide elements. In particular during the process, i.e. When the locking members are released, this improved drop rod guide ensures less wind sensitivity.

Zur Verhinderung von Laufgeräuschen und Reibungsverlusten ist in weiterer bevorzugter Ausgestaltung der Erfindung vorgesehen, daß in die Rohr- bzw. Hülsenenden Kunststoffbuchsen eingesetzt sind, welche die Reibung an den Führungselementen vermindern.To prevent running noise and friction losses, a further preferred embodiment of the invention provides that plastic bushings are inserted into the tube or sleeve ends, which reduce the friction on the guide elements.

Zweckmäßigerweise sind die Hohlelemente in ihrer wirksamen Länge verstellbar an den Fallstabenden befestigt. Dadurch läßt sich die Arretierstellung des Fallstabes in vertikaler Richtung besonders einfach korrigieren. Statt der variablen Befestigung der Hohlelemente an den Fallstabenden können alternativ auch die teller- bzw. scheibenförmigen Erweiterungen in verschiedenen Abständen zu den Fallstabenden an den Hohlelementen festlegbar sein. Eine längenvariable Befestigung läßt sich z.B. mit Hilfe von Gewinde- oder Rastverbindungen erreichen.The effective length of the hollow elements is expediently fastened to the ends of the drop rods in an adjustable manner. Thereby the locking position of the drop rod in the vertical direction can be particularly easily corrected. Instead of the variable fastening of the hollow elements on the ends of the drop bars, the plate-shaped or disk-shaped extensions can alternatively be fixed on the hollow elements at different distances from the ends of the drop bars. A variable-length attachment can be achieved, for example, with the aid of threaded or snap-in connections.

Nachfolgend wird anhand der beigefügten Zeichnungen näher auf ein Ausführungsbeispiel der Erfindung eingegangen. Es zeigen:

An exemplary embodiment of the invention is described in more detail below with reference to the accompanying drawings. Show it:
Fig. 1
a sketched representation of a sun protection curtain;
Fig. 2
an enlarged detail view of Figure 1 with the locking member not triggered;

Fig. 1 zeigt einen Sonnenschutzbehang 10, der eine Wickeleinrichtung 12, einen Fallstab 14 und einen zwischen Fallstab und Wickeleinrichtung gespannten Behang 15 aufweist. Der Fallstab 14 ist mit seinen Enden 16 an Führungsseilen 18 geführt, die zwischen der Wickeleinrichtung 12 und Haltewinkeln 20 gespannt sind. Die Haltewinkel 20 liegen dabei deutlich unterhalb der ausgefahrenen Endposition des Fallstabes 14.1 shows a sun protection curtain 10 which has a winding device 12, a drop bar 14 and a curtain 15 stretched between the drop bar and the winding device. The ends of the drop bar 14 are guided on guide ropes 18, which are stretched between the winding device 12 and holding brackets 20. The brackets 20 are clearly below the extended end position of the drop bar 14.

An den Fallstabenden 16 sind dünne Rohre 22 befestigt, an deren unteren Enden jeweils eine scheibenförmige Erweiterung 24 befestigt ist. An den Haltewinkeln 20 ist jeweils ein Arretierglied 26 befestigt, welches in seiner Ausführung dem in der Patentanmeldung 195 36 959.9 beschriebenen Arretierglied entspricht. Die Länge der dünnen Rohre 22 ist so bemessen, daß die scheibenförmigen Erweiterungen 24 an ihrem unteren Ende in der ausgefahrenen Endposition des Fallstabes 14 im Eingriffsbereich der Arme der Arretierglieder 26 liegen.At the ends of the drop rod 16, thin tubes 22 are attached, at the lower ends of which a disk-shaped extension 24 is attached. On the brackets 20 a locking member 26 is attached, which corresponds in its design to the locking member described in the patent application 195 36 959.9. The length of the thin tubes 22 is dimensioned such that the disk-shaped extensions 24 lie at their lower end in the extended end position of the drop bar 14 in the engagement area of the arms of the locking members 26.

Die Rohre 22 gestatten es, die Arretierglieder 26 im Bereich der Haltewinkel 20 anzuordnen und dennoch eine stabile Arretierung des Fallstabes 14 im Bereich der Führungsseile 18 sicherzustellen. Die Rohre 22, die am Fallstab winkelstarr befestigt sind, sorgen auch für dessen verbesserte Führung und verhindern ein Verkanten des Fallstabes 14 unter Windeinfluß, selbst wenn die scheibenförmigen Erweiterungen 24, z.B. während des Verfahrens des Fallstabes 14, nicht mit den Arretiergliedern 26 verriegelt sind. Der Einsatz der Rohre 22 ist deswegen auch in Sonnenschutzbehängen 10 ohne Arretierglieder 26 von Vorteil.The tubes 22 allow the locking members 26 to be arranged in the area of the holding brackets 20 and still ensure a stable locking of the drop bar 14 in the area of the guide cables 18. The tubes 22, which are fixed angularly to the drop rod, also ensure its improved guidance and prevent the drop rod 14 from tilting under the influence of wind, even if the disk-shaped extensions 24, e.g. are not locked with the locking members 26 during the movement of the drop rod 14. The use of the tubes 22 is therefore also advantageous in sun protection curtains 10 without locking members 26.

Zur Verbesserung der Laufeigenschaften sind in die Rohre 22 an deren Enden Kunststoffbuchsen eingesetzt (nicht gezeigt), die für einen spiel- und reibungsarmen Lauf des Fallstabes 14 beim Verfahren sorgen.To improve the running properties, plastic bushings (not shown) are inserted into the tubes 22 at their ends, which ensure that the drop rod 14 runs with little play and friction during the process.

Die Rastposition des Fallstabes 14 wird grob durch die Länge der Rohre 22 bestimmt. Zur vertikalen Feinausrichtung sind die Rohre 22 über eine Gewindeverbindung (nicht gezeigt) in die Fallstabenden 16 eingeschraubt. Durch einfaches Verdrehen der Rohre 22 läßt sich somit der Abstand zwischen den scheibenförmigen Erweiterungen 24 und dem Fallstab 14 korrigieren. Damit lassen sich herstellungsbedingte Toleranzen ausgleichen, und die Endposition des Fallstabes 14 kann exakt eingestellt werden. Statt der Gewindeverbindung kann auch eine Rastverbindung zwischen den beiden Elementen vorgesehen sein. Die Einstellbarkeit des Abstandes zwischen den scheibenförmigen Erweiterungen 24 und dem Fallstab 14 läßt sich selbstverständlich auch dadurch erreichen, daß man die scheibenförmigen Erweiterungen 24 selbst z.B. über eine Gewinde- oder Rastverbindung an den Rohren 22 befestigt.The latching position of the drop bar 14 is roughly determined by the length of the tubes 22. For vertical fine alignment, the tubes 22 are screwed into the drop rod ends 16 via a threaded connection (not shown). The distance between the disk-shaped extensions 24 and the drop bar 14 can thus be corrected by simply rotating the tubes 22. This allows manufacturing tolerances to be compensated, and the end position of the Drop bar 14 can be adjusted exactly. Instead of the threaded connection, a snap connection between the two elements can also be provided. The adjustability of the distance between the disk-shaped extensions 24 and the drop rod 14 can of course also be achieved by attaching the disk-shaped extensions 24 themselves to the tubes 22, for example via a threaded or snap-in connection.

Fig. 2 stellt eine Detailansicht eines Arretiergliedes 26 aus Fig. 1 dar. Der Fallstab 14 befindet sich in einer Stellung oberhalb der unteren Endposition, so daß auch die scheibenförmigen Erweiterungen 24 der Rohre 22 oberhalb des Eingriffsbereichs der Arretierglieder 26 liegen. Das Arretierglied 26 besitzt einen um einen Drehpunkt 27 schwenkbaren Hebel 28, der einen Auslösearm 30 und einen Arretierarm 32 aufweist.FIG. 2 shows a detailed view of a locking member 26 from FIG. 1. The drop rod 14 is in a position above the lower end position, so that the disk-shaped extensions 24 of the tubes 22 also lie above the engagement area of the locking members 26. The locking member 26 has a pivotable about a pivot point 27 lever 28 which has a release arm 30 and a locking arm 32.

Verfährt man den Fallstab 14 aus der Stellung nach Fig. 2 in Richtung seiner Endposition, stoßen die scheibenförmigen Erweiterungen 24 zunächst an die Auslösearme 30 der Hebel 28. Durch die Gewichtskraft des Fallstabes 14 wird der Hebel 28 über diesen Auslösearm 30 verdreht, bis er eine Totpunktstellung überwunden hat, die durch ein an einem Anlenkpunkt 33 am Hebel 28 angreifendes Federglied 34 erzeugt ist, welches in der Ausgangsstellung nach Fig. 2 den Hebel 28 in Anlage an einem Anschlag 35 hält. Unter dem Einfluß der Federkraft des Federglieds 34 schnappt der Hebel 28 in die Verriegelsstellung, wobei sich der Arretierarm 32 an die Oberseite der scheibenförmigen Erweiterung 24 anlegt (siehe Fig. 3). Die Arretierarme 32 der beiden Arretierglieder 26 erzeugen eine Vorspannung des gesamten Behangs, die dessen Windstabilität zugute kommt.If the drop rod 14 is moved from the position according to FIG. 2 in the direction of its end position, the disk-shaped extensions 24 first strike the release arms 30 of the lever 28. The weight of the drop rod 14 causes the lever 28 to be rotated via this release arm 30 until it is one Has overcome dead center position, which is generated by a spring element 34 acting on a pivot point 33 on the lever 28, which in the starting position according to FIG. 2 holds the lever 28 in contact with a stop 35. Under the influence of the spring force of the spring member 34, the lever 28 snaps into the locking position, the locking arm 32 resting against the top of the disk-shaped extension 24 (see FIG. 3). The locking arms 32 of the two locking members 26 generate a bias of the entire curtain, which benefits its wind stability.

Die dargestellte Ausführungsform des Arretiergliedes entspricht der in Fig. 3 und Fig. 4 der Patentanmeldung 195 36 959.9 dargestellten Ausführung. Bezüglich möglicher weiterer Ausführungformen der Arretierglieder soll jedoch nicht nur auf Fig. 1 und 2 dieser Patentanmeldung verwiesen werden, sondern es ist grundsätzlich auch der Einbau anderer Arretierglieder ohne Vorspannwirkung möglich, wenngleich damit auf das Optimum an Windstabilität verzichtet wird.The illustrated embodiment of the locking member corresponds to the embodiment shown in FIGS. 3 and 4 of patent application 195 36 959.9. With regard to possible further embodiments of the locking members, reference should not only be made to FIGS. 1 and 2 of this patent application, but it is also fundamentally possible to install other locking members without a pretensioning effect, although this does away with the optimum in wind stability.

Der grundsätzliche Vorteil der vorliegenden Erfindung besteht darin, den Fallstab 14 in Positionen zu arretieren, neben denen die Anordnung von Arretiergliedern 26 technisch unmöglich oder aus opischen Gründen nicht zu vertreten ist.The basic advantage of the present invention is to lock the drop rod 14 in positions next to which the arrangement of locking members 26 is technically impossible or is not justifiable for operational reasons.
