Description

Markise mit Druckausgleichlager Awning with pressure compensation bearing
Die Erfindung betrifft eine Markise, mit einem Markisengehäuse, das mittels Konsolen an einer Tragwand befestigbar ist, mit einer im Markisengehäuse drehbar aufgenommenen Tuchwelle, mit zumindest einem Schwenkarm, der einerseits am Markisengehäuse und andererseits gelenkig mit einer Fallstange verbunden ist, an der ein Ausfallende eines auf der Tuchwelle aufgewickelten Tuches befestigt ist.The invention relates to an awning, with an awning housing which can be fastened to a supporting wall by means of brackets, with a fabric shaft rotatably received in the awning housing, with at least one swivel arm which is articulated on the one hand on the awning housing and on the other hand articulated with a drop bar on which a dropout is attached attached to the cloth shaft wound cloth.
Eine derartige Markise ist aus der DE 42 09 972 AI bekannt. Bei bekannten Markisen dieser Art biegt sich die Tuchwelle insbesondere beim Ausfahren des Markisentuches aufgrund der hierbei auftretenden Zugkräfte im wesentlichen nach vorne, also in Ausfahrrichtung aus. Dies wirkt sich negativ auf den Durchhängegrad des Markisentuches sowie auf die Position der Fallstange in bezug auf das Markisengehäuse aus. Auch die Fallstange biegt sich aus, wie das schematisch in der beiliegenden Fig. 1 dargestellt ist. Wird das Tuch wieder eingezogen, kann sich die gekrümmte Fallstange nicht mehr dicht an das Markisengehäuse anlegen, so daß Feuchtigkeit und Verschmutzung eindringen kann. Beim Aufwickeln entstehen im mittigen Bereich der gebogenen Tuchwelle erhebliche Wickelfalten. Dadurch entstehen ungünstige Reibungsverhältnisse im Mittenbereich des aus einer Anzahl sich überlappender Einzelmaterialbahnen gefertigten Markisentuches bei dessen Durchtritt durch den im Markisengehäuse ausgebildeten Führungskanal bzw. Führungsspalt.Such an awning is known from DE 42 09 972 AI. In the case of known awnings of this type, the fabric shaft bends essentially forward, that is to say in the direction of extension, particularly when the awning fabric is extended due to the tensile forces which occur in this case. This has a negative impact on the sagging level of the awning cover and the position of the drop bar in relation to the awning housing. The drop bar also bends, as is shown schematically in the accompanying FIG. 1. If the fabric is pulled back in, the curved drop bar can no longer lie close to the awning housing, so that moisture and dirt can penetrate. When winding, considerable folds appear in the central area of the curved fabric shaft. This creates unfavorable frictional conditions in the center area of the awning fabric made from a number of overlapping individual material webs when it passes through the guide channel or guide gap formed in the awning housing.
Es ist Aufgabe der Erfindung, ein Ausbiegen der Tuchwelle insbesondere beim Aus- und Einfahren des Markisentuches weitgehend zu verhindern.It is an object of the invention to largely prevent the fabric shaft from bending, particularly when the awning fabric is extended and retracted.
Erfindungsgemäß wird dies dadurch gelöst, daß die Tuchwelle federelastisch nachgiebig abgestützt ist. Diese Maßnahme hat nun den Vorteil, daß die Kräfte, die dazu führen, daß sich die Tuchwelle durchbiegen kann, durch die federelastisch nachgiebige Abstützung aufgefangen werden. Diese Kräfte verursachen nun nicht mehr ein Durchbiegen der Tuchwelle sondern resultieren in einer Bewegung der Tuchwelle in der federelastisch nachgiebigen Abstützung. Daraus resultiert eine hervorragende Parallelität zwischen Tuchwelle und Fallstange, so daß keine Wickelfalten mehr beim Aufwickeln auftreten können.According to the invention, this is achieved in that the cloth shaft is resiliently supported. This measure now has the advantage that the forces that cause the fabric shaft to bend are absorbed by the resilient support. These forces no longer cause the fabric shaft to bend, but instead result in a movement of the fabric shaft in the resilient support. This results in excellent parallelism between the fabric shaft and the drop bar, so that no creases can occur when winding up.
Die Federelastische Abstützung sorgt auch dafür, daß ein Durchhängen des Tuches vermindert wird. Dadurch, daß sich die Tuchwelle nun nicht mehr durchbiegen kann, und somit auch nicht mehr die Fallstange durchgebogen werden kann, kann letztere geradlinig dichtend an das Markisengehäuse herangezogen werden. Dadurch, daß keine Wickelfalten mehr auftreten, wird die Reibung an den Nähten des Tuches erheblich vermindert, was der Lebensdauer des Tuches äußerst zuträglich ist.The spring-elastic support also ensures that sagging of the cloth is reduced. Due to the fact that the fabric shaft can no longer bend, and thus the drop bar can no longer be bent, the latter can be used in a straight-line sealing manner on the awning housing. Because there are no more wrinkles, the friction at the seams of the cloth is considerably reduced, which is extremely beneficial to the life of the cloth.
Ein weiterer erheblicher Vorteil in der federelastischen nachgiebigen Abstützung besteht darin, daß Vibrationen, z.B. von Elektroantrieben, durch diese Lagerung erheblich gedämpft werden und nicht auf das Bauwerk übertragen werden.Another significant advantage in the resilient resilient support is that vibrations, e.g. of electric drives, are dampened considerably by this storage and are not transferred to the building.
Weiterbildungen und zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen aufgeführt.Further developments and expedient refinements of the invention are listed in the subclaims.
Die Erfindung wird im Nachstehenden anhand der Zeichnung näher beschrieben und erläutert. Es zeigen:The invention is described and explained in more detail below with reference to the drawing. Show it:
Fig. 1 eine Prinzipskizze einer Markise mit ausgebogener Tuchwelle,1 is a schematic diagram of an awning with a bent fabric shaft,
Fig. 2 einen Längsschnitt durch das Markisengehäuse, Fig. 3 eine Innenansicht einer der beiden das Markisengehäuse an seinen Stirnseiten abschließenden Endkappen, in der ein den einen Lagerzapfen der Tuchwelle aufnehmendes, unter Federwirkung stehendes Schlittenelement gleitend verschiebbar angeordnet ist,2 shows a longitudinal section through the awning housing, 3 is an interior view of one of the two end caps closing the awning housing on its end faces, in which a slide element which receives the bearing journal of the fabric shaft and is under spring action is slidably arranged,
Fig. 4 einen Teillängsschnitt durch eine Endkappe mit auf in der Endkappe angeordneten Rollkörpern verschiebbar geführten Schlittenelementen,4 shows a partial longitudinal section through an end cap with slide elements guided displaceably on rolling elements arranged in the end cap,
Fig. 5 eine Ansicht entsprechend Fig. 3, jedoch mit kugelgelagerten Schlittenelementen,5 is a view corresponding to FIG. 3, but with ball-bearing slide elements,
Fig. 6 einen Querschnitt durch das Markisengehäuse mit einem der Tuchwelle zugeordneten Stützkörper.Fig. 6 shows a cross section through the awning housing with a support body assigned to the fabric shaft.
Fig. 1 zeigt schematisch die ausgebogene Tuchwelle 14 sowie die gekrümmte Fallstange 32 einer Markise, deren Schwenkarme 6, 6' und 7, 7' einerseits an die Fallstange 32 und andererseits schwenkbar an die das Markisengehäuse 10 aufnehmenden Konsolen 8, 9 angelenkt sind.Fig. 1 shows schematically the bent fabric shaft 14 and the curved drop bar 32 of an awning, the pivot arms 6, 6 'and 7, 7' on the one hand to the drop bar 32 and on the other hand pivoted to the brackets 8, 9 receiving the awning housing 10.
Wie aus Fig. 2 ersichtlich ist, ist das Markisengehäuse 10 an beiden Stirnseiten durch jeweils eine Endkappe 11, 12 abgeschlossen. Der eine Lagerzapfen 13 der Tuchwelle 14 ist unmittelbar in einem mit einer passenden Aufnahmebohrung 15' versehenen Schlittenelement 15 und der andere Lagerzapfen 16 der Tuchwelle in einem mit einem gleichartigen Schlittenelement 17 vereinigten, eine Aufnahmebohrung 17' aufweisenden Lagerschild 18 drehbar gelagert, der mit dem Schlittenelement 17 durch Schrauben 19 oder dergleichen Befestigungselemente verbunden ist .As can be seen from FIG. 2, the awning housing 10 is closed at both ends by an end cap 11, 12. One bearing pin 13 of the cloth shaft 14 is rotatably mounted directly in a slide element 15 provided with a suitable receiving bore 15 'and the other bearing pin 16 of the cloth shaft in a bearing plate 18 which is united with a similar slide element 17 and has a receiving hole 17' and which carries the slide element 17 through Screws 19 or the like fasteners is connected.
Die beiden Schlittenelemente 15 und 17 sind jeweils mit zwei Ausnehmungen 20, 21 für die Aufnahme, Führung und Abstützung jeweils eines Endbereichs von federelastischen Bauelementen 22, 23 versehen, die, wie auch Fig. 3 zeigt, mit ihrem anderen Ende auf Flächen 24, 25 der in den beiden Endkappen 11, 12 jeweils angebrachten Begrenzungs- und Führungsrahmen 26, 27 aufliegen.The two slide elements 15 and 17 are each provided with two recesses 20, 21 for receiving, guiding and supporting an end region of resilient components 22, 23 which, as also shown in FIG. 3, have their other end on surfaces 24, 25 of the limiting and guide frames 26, 27, which are respectively attached in the two end caps 11, 12.
Anstelle der hier als Druckfedern ausgebildeten federelastischen Bauelemente können auch Zugfedern verwendet werden, die einerseits am Begrenzungsrahmen 26 verankert werden und andererseits unmittelbar am jeweiligen Schlittenelement angreifen können.Instead of the spring-elastic components designed here as compression springs, tension springs can also be used, which are anchored on the one hand on the delimiting frame 26 and, on the other hand, can act directly on the respective slide element.
Die Anzahl und Ausgestaltung der Federelemente richtet sich nach der jeweils erforderlichen bzw. günstigsten resultierenden Federkonstanten .The number and design of the spring elements depend on the respectively required or cheapest resulting spring constants.
Die unter Federwirkung stehenden Schlittenelemente 15 und 17 sind in dem Führungsrahmen 27 der zugehörigen Endkappe gleitend verschiebbar geführt und in ihrer jeweiligen Auslenkung durch den Begrenzungsrahmen 26 festgelegt. Um den Reibungskoeffizienten möglichst gering zu halten, können die Gleitflächen der Schlittenelemente 15 und 17 und gegebenenfalls auch die diesen zugeordneten Führungsbahnen mit einem reibungsarmen Belag, z.B. mit einer Schicht aus Teflon, versehen sein bzw. aus einem geeigneten Kunststoff bestehen. Zur Erleichterung der Montage der Schlittenelemente in der jeweiligen Endkappe 11 bzw. 12 ist an jedem Ende des Schlittenelements eine Führungsstange 27, 29 angebracht, denen eine Halteschraube 30, 31 zugeordnet ist.The spring-loaded slide elements 15 and 17 are slidably guided in the guide frame 27 of the associated end cap and are fixed in their respective deflection by the limiting frame 26. In order to keep the coefficient of friction as low as possible, the sliding surfaces of the slide elements 15 and 17 and possibly also the guide tracks assigned to them can be provided with a low-friction coating, for example with a layer of Teflon, or consist of a suitable plastic. To facilitate the assembly of the slide elements in the respective end cap 11 or 12, a guide rod 27, 29 is attached to each end of the slide element, to which a retaining screw 30, 31 is assigned.
Die Eingriffsnut 34 der Tuchwelle 14 für die Verankerung des Markisentuchs 35 ist in den Figuren 2 und 3 gestrichelt angedeutet. Im Falle der Fig. 2 kennzeichnet das Bezugszeichen 33 eine Stützschale für das Markisentuch. Der Markisenantrieb mit Getriebe ist der Übersicht halber nicht angedeutet.The engagement groove 34 of the fabric shaft 14 for anchoring the awning fabric 35 is indicated by dashed lines in FIGS. 2 and 3. In the case of Fig. 2, reference numeral 33 denotes a support shell for the awning fabric. The awning drive with gear is not indicated for the sake of clarity.
Beim Ausführungsbeispiel nach Fig. 4 sind die beiden Schlittenelemente 15 und 17 auf in den beiden Endkappen 11 und 12 des Markisengehäuses 10 angebrachten Rollenkörpern 37 verschiebbar angeordnet. In Fig. 4 ist nur die Endkappe 11 dargestellt, die Endkappe 12 ist entsprechend spiegelbildlich ausgestaltet. Ein Doppelpfeil zeigt die Verschiebebewegungen der Tuchwelle 14 aufgrund der nachgiebigen Abstützung der Tuchwelle 14 im Markisengehäuse über die Feder 22. Kräfte, die auf die Tuchwelle 14 einwirken, führen daher nicht zu einem Durchbiegen der Tuchwelle 14 sondern werden über das Druck-Ausgleichlager aufgenommen.In the embodiment according to FIG. 4, the two slide elements 15 and 17 are arranged displaceably on roller bodies 37 attached in the two end caps 11 and 12 of the awning housing 10. In Fig. 4 only the end cap 11 is shown, the end cap 12 is designed in mirror image accordingly. A double arrow shows the sliding movements of the fabric shaft 14 due to the resilient support of the fabric shaft 14 in the awning housing via the spring 22. Forces that act on the fabric shaft 14 therefore do not cause the fabric shaft 14 to bend but are absorbed by the pressure compensation bearing.
Fig. 5 zeigt eine Lösung, bei der die Schlittenelemente 15, 17 jeweils mit Kugellagern 38 versehen sind, die auf den Führungsrahmen 27 rollen.Fig. 5 shows a solution in which the slide elements 15, 17 are each provided with ball bearings 38 which roll on the guide frame 27.
Bei der Ausführungsvariante gemäß Fig. 6 ist der Tuchwelle 14 bzw. dem auf dieser befindlichen Tuchwickel ein unter der Wirkung von Federn 39, 40 stehender, sich in Umfangsrichtung der Tuchwelle erstreckender Stützkörper 41 zugeordnet, der mit auf der Tuchwelle aufliegenden Rollen 42, 42 versehen und zur selbsttätigen Anpassung an die Durchmesseränderungen des Tuchwellenwickels radial zur Tuchwellenachse verschiebbar ist.In the embodiment variant according to FIG. 6, the cloth shaft 14 or the cloth roll located thereon is associated with a support body 41, which is under the action of springs 39, 40 and extends in the circumferential direction of the cloth shaft and which also extends to the rollers 42, 42 resting on the fabric shaft and can be displaced radially to the fabric shaft axis for automatic adaptation to the changes in diameter of the fabric shaft winding.
Die vorzugsweise jeweils in einer Ausfräsung 43' der Armlager 43 untergebrachten Stützkörper 41 sind jeweils als Y-förmig gestaltete zweiarmige Rollenträger ausgebildet, deren Arme 44, 45 sich jeweils in Umfangsrichtung der Tuchwelle 14 erstrecken und an ihrem Endbereich die Rollen 42, 42' tragen. Die beiden Arme 44, 45 des jeweiligen Stützkörpers 41 gehen in ihrem der Tuchwelle abgewandten Bereich unter entsprechender Krümmung in ein radial zur Tuchwellenachse verlaufendes Führungsteil 46 über, das einen Längsschlitz 47 enthält, in den ein am Armlager 43 angebrachter Führungsstift 48 eingreift, so daß der Stützkörper 41 den Änderungen des Wickeldurchmessers der Tuchwelle selbsttätig folgen kann.The support bodies 41, which are preferably each accommodated in a cutout 43 'of the arm bearings 43, are each designed as a Y-shaped two-arm roller carrier, the arms 44, 45 of which each extend in the circumferential direction of the fabric shaft 14 and carry the rollers 42, 42' at their end region. The two arms 44, 45 of the respective support body 41 go in their area facing away from the fabric shaft with a corresponding curvature into a radially extending to the fabric shaft axis guide member 46 which contains a longitudinal slot 47 into which a guide pin 48 attached to the arm bearing 43 engages, so that the Support body 41 can automatically follow the changes in the winding diameter of the cloth shaft.
In den Krümmungen 49, 50 des Stützkörpers 41 sind Anlageflächen für die hier sowohl zur Tuchwellenachse als auch zueinander geneigt angeordneten Federn 39, 40 angearbeitet, deren andere Enden sich an Paßflächen 51, 52 der Armlager 43 abstützen.In the curvatures 49, 50 of the support body 41, contact surfaces for the springs 39, 40 arranged here both inclined to the axis of the fabric shaft and to one another are worked on, the other ends of which are supported on mating surfaces 51, 52 of the arm bearings 43.
Der jeweilige Neigungswinkel der Federn wie auch deren Konstante richten sich nach den jeweils zu erwartenden relevanten Kraft- und Drehmomentkomponenten nach Richtung und Größe.The respective angle of inclination of the springs as well as their constant depend on the relevant force and torque components to be expected according to direction and size.
Anstelle von Druckfedern können auch aus einem anderen Material bestehende bzw. anders gestaltete federelastische Elemente verwendet werden. Die Anzahl der je Tuchwelle vorzusehenden Stützkörper 41 richtet sich grundsätzlich nach den Abmessungen der Markisen (Länge der Tuchwelle, deren Durchmesser, ausfahrbare Länge des Markisentuchs). Gegebenenfalls kann jeder Überlappungszone des aus sich gegenseitig überlappenden Einzelmaterialbahnen zusammengesetzten Markisentuchs ein Stützkörper 41 zugeordnet sein, für den dann, abgesehen von den Ausfräsungen 43' in den Armlagern 43, Abstützflächen für die Federn 39, 40 im Markisengehäuse 10 vorzusehen sind. Wesentlich ist, daß ein Ausbiegen der Tuchwelle 14 mit den damit verbundenen Nachteilen zumindest weitgehend verhindert wird, insbesondere auch eine Übereinstimmung der Lage der Fallstange 32 zum Markisengehäuse 10 gewährleistet ist.Instead of compression springs, spring-elastic elements made of a different material or designed differently can also be used. The number of support bodies 41 to be provided for each fabric shaft is generally based on the dimensions of the awnings (length of the fabric shaft, its diameter, extendable length of the fabric). If necessary, a support body 41 can be assigned to each overlap zone of the awning fabric composed of mutually overlapping individual material webs, for which support surfaces for the springs 39, 40 in the awning housing 10 are then to be provided, aside from the cutouts 43 'in the arm bearings 43. It is essential that bending of the fabric shaft 14 with the associated disadvantages is at least largely prevented, in particular that the position of the drop bar 32 relative to the awning housing 10 is also ensured.
Stützkörper der beschriebenen oder ähnlicher Art können sowohl bei herkömmlicher Lagerung der Tuchwelle 14 als auch in Kombination mit deren federelastischer Lagerung entsprechend einem der in den Figuren 2 bis 5 festgehaltenen und beschriebenen Ausführungsbeispiele verwendet werden.Supporting bodies of the type described or similar can be used both in the conventional mounting of the fabric shaft 14 and in combination with its spring-elastic mounting in accordance with one of the exemplary embodiments which are recorded and described in FIGS. 2 to 5.
Die Amplitude der Ausbiegung der Tuchwelle 14 bzw. deren federelastischer Verschiebungsweg ist in Fig. 6 gestrichelt angedeutet. Bei eingefahrenem Markisentuch weist die Tuchwelle 14 eine von ihrer jeweiligen geometrischen und mechanischen Ausgestaltung abhängige Durchbiegung auf.The amplitude of the deflection of the fabric shaft 14 and its resilient displacement path is indicated by dashed lines in FIG. 6. When the awning fabric is retracted, the fabric shaft 14 has a deflection which is dependent on its respective geometric and mechanical configuration.
Das Markisentuch kann aus textilem Material, einer Mischung aus Textil- und Kunststoffasern oder auch aus einem geeigneten Kunststoff bestehen. The awning cloth can consist of textile material, a mixture of textile and plastic fibers or of a suitable plastic.
